Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a feces drying device for drying feces of chickens, pigs, cows, etc.
In particular, the present invention relates to a feces drying bag assembly consisting of a combination of a furnace and a double cylinder.

Conventionally, a drying apparatus comprising a furnace and a double cylinder has been proposed, for example, a sludge incineration apparatus described in Japanese Tokkoku Seki No. 50-108768.

However, this device has a structure in which the furnace and the double cylinder are installed in parallel, and the ends of both are passed through a connecting chute, so the material to be dried in the double cylinder is It is only dried by the atmosphere inside the furnace flowing through the furnace.
Therefore, sufficient drying cannot be achieved, and the dried material taken out from the double barrel remains in a semi-dry state. In addition, the exhaust gas (exhaust smoke) from inside the furnace passes through the communication chute, passes through the gap between the inner cylinder and the outer tube, and is then introduced into the exhaust system through the inner cylinder, but the passage is long and curved. Because it is curved, there is a lot of resistance and the exhaust efficiency is extremely poor. Therefore, the inside of the furnace is like a high-pressure cooker, and the furnace deteriorates quickly, and there is a risk of explosion due to abnormal overheating. Moreover, since the furnace has a structure in which the dried material is forcibly incinerated using a burner, it consumes a large amount of fuel such as heavy oil, which is the fuel for the burner, and the economic burden on fuel costs is large. be. In view of such circumstances, the present invention has a vertical furnace, and one end of the inner cylinder is inserted into the upper part of the furnace so as to be rotatable in the horizontal direction. The drying efficiency and exhaust efficiency are improved by forming a duct that connects the hot air outlet formed in the upper part of the furnace and one end of the inner cylinder, and further improving the drying efficiency and the exhaust efficiency. Multiple air ejection pipes are installed at the bottom of the
By increasing the oxygen supply rate, the material to be dried is formed so as to be combustible, thereby reducing the amount of fuel used in the burner. In addition, in the second invention, in order to use the dried dung as fuel, a conveying device is provided between the dung outlet and the fuel intake of the furnace, and not only a part of the dried dung but also a portion of the dried dung is used. By automatically transporting all of the waste into the furnace and eliminating the need for a burner, we aim to contribute to the national energy conservation policy. This will be explained according to the drawings.

First, the first aspect of the invention will be explained based on the illustrated embodiments as follows.

21 is an inner cylinder with both ends closed, and one end of the inner cylinder 2 is inserted into the upper part of the furnace volume so as to be freely rotatable in the lateral direction.

Incidentally, as shown in the figure, the end of the inner cylinder 2 on the side where the tube is inserted, that is, the base end, may be provided with a metal part 2b directed toward the center of the diameter to prevent the hollyhock from rebounding. In addition, the inner cylinder 2 inserted laterally into the upper part of the furnace shell is not limited to the case where it passes through the furnace shell as shown in the figure, but may be configured so that its end faces into the furnace. The outer cylinder 3, which is closed at both ends, is secured by a plurality of supports i5 so as to cover the portion of the inner cylinder 2 protruding from the furnace 1, and rotates in the same manner as the inner cylinder 2. The tip of the outer tube 3 is made to protrude beyond the tip of the inner tube 2, and the inside of the inner tube 2 is formed between the outer periphery of the inner tube 2 and the inner periphery of the outer tube 3 at the tip. The tip of the outer cylinder 3 is provided with a poisonous part 3b directed toward the center of the diameter, and the metal part 3b is
A protruding cylinder 3' with both ends open is provided concentrically with the outer cylinder 3. Although not shown, the inner tube 2 and the outer tube 3 may be rotated separately and independently. A plurality of swash plates 2a are provided on the inner walls of the inner cylinder 2 and the outer cylinder 3 to send the excrement forward.
3a and 3a' are provided.

A swash plate 2a on the inner wall of the inner section 2 and a swash plate 3 on the outer cylinder 3
a and 3a', when the inner cylinder 2 and the outer cylinder 3 rotate in the same direction as in this embodiment, the mounting angle of the swash plate is reversed as shown in the figure, but the inner cylinder 2 and the outer cylinder 3 rotate in opposite directions, the mounting directions of the swash plates are the same. 171 is an iron driving roller that supports the outer cylinder 3 via a plurality of iron rings 16 provided along the outer periphery of the outer cylinder 3.
The double cylinder A consisting of the inner cylinder 2 and the inner cylinder 2 is made rotatable (see Fig. 6).

Incidentally, the rotation mechanism of the double tube A may be constructed using a chain as shown in FIG. 7H. Further, the case where the inner tube 2 and the outer tube 3 are rotated separately and independently is not limited to this embodiment. Reference numeral 4 denotes a hot air conveying duct, which is arranged to flow into the inner cylinder 2 from the base end side of the inner cylinder 2 via a blower 5 from a hot air outlet lb bored in the upper surface of the furnace 1.

Although not shown, a burner may be installed inside the proximal end of the inner cylinder 2, that is, near the outlet of the hot air conveying duct 4. The screw comparer 7 is installed and its outlet is connected to the inner cylinder 2.
It is closed into the inner cylinder 2 from the proximal end side.

28' is a shielding plate.

At the tip of the tip protruding register 3' of the outer cylinder 3, there is ~ the protruding cylinder 3.
A suction tube blade crab through which the duct 2 is rotatably inserted is installed.
Military: Fits into shower 22 and chimney 28.

Note that the order of the individual devices in the series of exhaust devices described above is not limited to this example. A feces removal port 38 is bored along the outer periphery at the base end position of the outer section 3, that is, on the furnace side. The outer cylinder 3
The proximal end of the furnace is provided with a flange 3c that extends toward the center of the diameter to prevent dried feces from entering the Sekiguchi part a of the furnace neck (see Figure 3).
.

However, even in this case, there is a gateway 36 between the metal pipe 3 and the inner cylinder 2, so that at least the hot air inside the furnace is introduced into the transfer path 29. By providing the flange 3c in this way, it is possible to prevent dried feces from entering the furnace 1 to some extent, but the present invention does not completely prevent such dry feces from entering. In fact, it can be said that returning the excrement to the furnace is preferable.
The vine Q' is a dry feces extractor which is provided with a receiver □ at a position corresponding to the feces outlet 3 when the feces outlet 3d comes directly below as the outer cylinder 3 rotates, and 10a is the dry feces extractor. This is a screw comparator installed at the bottom of the extractor 10. Reference numeral 10b denotes a cover provided integrally with the dried feces extractor 10 over the outer periphery of the outer cylinder 3 in order to prevent heat from dissipating from the feces outlet 3d.

The air blowing pipe 8 is equipped with a blower 2 as an air supply source.
7 is provided, or air is supplied from the heat exchanger 21 to the air ejection pipe 8 using a suction machine 25 and a pipe 26. This air ejection pipe 8 also actually has the function of a roistle. An ash removal port 9b is provided at the bottom of the basin-shaped ash removal device 9, and a screw comparer 9a is provided to remove the ash. Note that it is also possible to scrape out with a pocket or the like without providing the screw comparer 9a. The ignition burner has a crater in the combustion chamber B of the Mikawa Furnace 1, and lc is a fuel intake port that can be opened and closed to take in dried feces and the like.

M and M indicate the drive mechanism of the screw comparer 7, M4 and M5 respectively indicate the drive mechanism of the screw comper 10a, the drive mechanism of the drive roller 17, and the drive mechanism of the screw comper 9a at the ash removal port 9b. Incidentally, the overall outline of such an apparatus is as illustrated in the perspective view of FIG. 8.
To carry out the hawking constructed as described above, first, the drive mechanisms M, , M4 are driven to rotate the screw comparer 7 and the double cylinder A.

Next, the burner 30 is ignited and air is ejected from the air ejection pipe 8 in the furnace 1 to burn wood chips, dried dung, etc. that have been previously introduced into the combustion chamber B through the fuel intake port lc. Once these start burning, the burner 30 is turned off. When the inside of the furnace 1 becomes high temperature, heated air is sucked from the upper part of the furnace 1 by a blower 5, and the hot air is radiated into the inner cylinder 2 through the hot air conveying duct 4. And chicken,
When raw excrement from pigs, cows, etc. is put into the hopper 6, the raw excrement is conveyed into the inner cylinder 2 by the screw conveyor 7.

The raw excrement conveyed into the inner cylinder 2 is dried by hot air radiated from the outlet of the duct 4, and is sent forward by a swash plate 2a attached to the inner wall of the inner cylinder 2. The excrement that has reached the tip of the inner tube 2 falls into the transfer path 29 formed in the gap between the inner tube 2 and the outer tube 3, and is moved to the inner tube by the swash plates 3a and 3a' attached to the inner wall of the outer tube 3. It is sent in the opposite direction to the inside of the cylinder 2. The figure that has reached the base end of the outer cylinder 3 falls into the dried feces extractor 10 when the feces outlet 3d comes directly below as the outer cylinder 3 rotates. The dried excrement is discharged through the screw comperor 10a by driving the drive mechanism M3. A necessary amount of the dried excrement thus taken out as fuel is introduced into the combustion chamber B through the fuel intake port lc.

Since the dung thrown into the combustion chamber B is already sufficiently dried, it is easily combusted only by the air supply V from the air jet pipe 8. Then, if the dried dung is thrown in as appropriate, the fuel using the dried dung continues in the furnace 1, and the hot air generated at that time is sent into the inner cylinder 2 through the duct 4, and the inside of the furnace 1 is filled. The inner cylinder 2 is directly heated, and the transfer path 2
The hot air also reached 9. The hot air radiated from the outlet of the duct 4 blows through the inner tube 2, and the heat from the furnace 1 blows through the transfer path 29, passes through the suction tube 18 together with odor, and is sent to the blower 19, the cyclone 20, and the heat by the duct 24. It passes through the exchanger 21 and the shower 22 and is sent to the chimney 2 as exhaust air.
It is dissipated from 3. Further, the ash accumulated in the furnace 1 is periodically taken out from the ash outlet gb. or,
As shown in FIG. 2, the second invention adds the following configuration to the first invention.

That is, 11 is a hopper that receives the dried feces discharged from the screw compare 10a of the dried feces extractor 10, and the hopper 11 has a dried feces outlet 11a at the bottom and a screw comper 12a inside. Conveyance path 1 having
Connect the two inlet parts. 0 The other end, ie, the outlet, of the conveyance path 12 is made to fit more into the furnace 1 than the fuel intake port lc of the furnace 1.

The configuration from the outlet of the conveyance path 12 to the inside of the furnace 1 is as follows. First, the exit part of the conveyance path-12 is connected to the hopper 13.
And make the lotus suitable. Reference numeral 14 designates a screw comperor provided from the bottom of the scallop parr 13 to the fuel intake port lc, and a rotary blade 14a is provided at the exit portion of the screw compressor for introducing the drying blade into the furnace 1 (see Fig. 4). .

In order to prevent the main shaft 14b of the rotary vane 14a from being deformed due to the high heat in the furnace, a mechanism may be used in which cold water is circulated within the main shaft 14b (see FIG. 5). In addition, there is an initial fuel intake port ld that takes in the fuel required when starting the device.
may be provided on the side wall of the furnace 1. Furthermore, although not shown, in order to keep the firepower in the furnace constant by adjusting the input amount of dried feces, devices are installed to adjust the drive of the screw comper 14 and the screw comparator 12a in the conveyance path 12, respectively. establish. M2 indicates a drive mechanism for the screw comparator 14, and M6 indicates a drive mechanism for the screw comparator 12a in the conveyance path 12. Incidentally, an outline of the entire equipment is as illustrated in the perspective view of FIG. 9. According to the device configured as described above, the feces that have reached the base end of the outer cylinder 3 will be transported into the dry form extractor 10 when the feces outlet 3d comes directly below as the outer cylinder 3 rotates. Fall.

The dried excrement is conveyed into the hopper 11 via the screw conveyor 10a by driving the drive mechanism M3. Next, the drive mechanism M6 is driven to transport the dried excrement carried into the hopper 11 into the hopper 13 through the transport path 12.

The dried excrement carried into the hopper 13 is guided into the furnace 1 by the screw comperor 14 by driving of the drive mechanisms M2 and M7, and is thrown into the furnace 1 by the rotation of the rotary blade 14a as shown in FIG. It will be done. As described above, according to the present invention, hot air is sent into the inner cylinder through the hot air conveying duct, and the inner cylinder part that is inserted into the furnace is directly heated, and the entrance part provided at the base end of the outer cylinder is heated directly. Since the hot air also reaches the transfer path, the efficiency of drying the excrement can be increased.

That is, the feces in the inner cylinder are directly heated by the hot air from the duct and by heating the inner cylinder, and the feces in the transfer path are indirectly heated by the hot air. This makes it possible to dry feces efficiently. In addition, since the duct is suitable for the hot air discharge port in the upper part of the furnace, it is possible to improve the exhaust efficiency in the furnace, and not only does the pressure inside the furnace not rise abnormally, but it also promotes combustion. It also helps. Furthermore, several air ejection pipes installed at the bottom of the furnace play the role of a roistle, and the supply of air from the air ejection pipes has the effect of promoting combustion due to the aforementioned improvement in exhaust efficiency. This makes it possible for materials to self-combust, and unlike the conventional drying equipment (1 tatami mat), it is possible to save fuel (heavy oil) used in the burner. Next, according to the second invention, in addition to the effects of the first invention, since the dried dung is automatically put into the furnace, the dung is dried only by the combustion heat of the dried dung. This will greatly contribute to national energy conservation measures.
