Description

[Detailed Description of the Invention] The present invention is a separator for ready-mixed concrete, sandstone, etc., and more specifically, a separator for ready-mixed concrete, sandstone, etc. Ready-mixed concrete, etc., can be separated into stones, sand, and cement-dissolved water in a short period of time, and collected separately. This relates to a separator for sandstone, etc.

The first object of the present invention is to charge fresh concrete, sandstone, etc. into the sieve tube from the rear of the sieve tube, and collect the separated sand and stones from the front of the sieve tube. , Improved ready-mixed concrete that allows the opening of the rear cylinder lid or auxiliary cylinder to be enlarged, thereby lowering the charging position and allowing it to be directly poured from a mixer truck or the like without using a machine such as a sand pump. Our objective is to provide separators for sand, stone, etc.

The second object of the present invention is that since the separated sand and stones are collected from the front of the sieve tube as described above, the separation and collection section for sand and stones is used in conjunction with the entire length of the separator. An object of the present invention is to provide an improved separator for ready-mixed concrete, sand and stone, etc., which can shorten the time required to separate the raw concrete and sandstone.

A third object of the present invention is to improve the efficiency of the sieve and prevent clogging by forming the rear tube of the sieve tube by arranging round rods in a cylindrical shape with appropriate gaps. To provide an improved separator for fresh concrete, sand and stone, etc., which can easily remove clogging even if it is difficult to do so.

A fourth object of the present invention is to provide improved ready-mixed concrete, sand stone, etc. that can more effectively drain the sand when discharging the sand in the water tank using an outer spiral blade provided on the outer periphery of the sieve tube. Our goal is to provide separators for

The objects and features of the invention will be better understood from the following detailed description and accompanying drawings.

An embodiment of the separator for fresh concrete, sand and stone, etc. of the present invention is shown in FIGS. 1 and 2.

In FIG. 1, a sieve tube 1 is constructed by connecting a front tube 3 whose diameter gradually decreases to the front end of a rear tube 2, and an auxiliary tube 4 whose diameter gradually decreases toward the rear to its rear end.

The center of the rear end of the auxiliary tube 4 has an opening 5, but in the case of a sieve tube where the auxiliary tube 4 is not connected, a lid having an opening in the center is attached to the rear end of the rear tube 2. be done.

The sieve tube 1 has a rear tube 2 which is formed by arranging round bars 2a in a cylindrical shape with appropriate gaps between them, and the front tube 3 has numerous small holes 6 on its outer circumferential surface, and inside thereof. An inner spiral blade 7 is attached to the periphery, an outer spiral blade 8 is attached to the outer periphery of the cylinder 2 and the front cylinder 3, and a shaft 9 is attached to the center of the blade and is arranged horizontally and rotatably.

A portion of the sieve tube 1 slightly behind the front end of the outer spiral blade 8 is bent forward to form a bent portion 10.

Next, the water tank 11 has a bridge shape in which approximately the lower half of the sieve tube 1 enters and the approximately half facing the outer peripheral surface of the lower half of the outer spiral blade 8 has a similar shape to the outer peripheral surface of the outer spiral blade 8. Yes A partition 13 having a drain port 12 is provided at the rear end.

The opening at the front end of the water tank 11 is closed to an appropriate height by a partition 14, and the bent portion 1 of the outer spiral blade 8
0 allows the sand 15 in the water tank 11 to be drained when the sand 15 is discharged.

In the drawing, 16 is an inlet for fresh concrete, sandstone, etc. and water, 17 is a stone, 18 is a water surface, and 19 is a support rod.

In the above configuration, the outer spiral blades 8 attached to the outer periphery of the sieve tube 1 are preferably attached a little apart from the outer periphery, for example by the support rods 19, so that the outer periphery of the sieve tube 1 and the outer spiral blades 8 are Since water freely flows out from the gap with the inside, it is possible to drain the water and collect only the sand 15.

Next, to explain the operation of the separator for fresh concrete, sand and stone, etc. of the present invention, first, from the input port 16 to the sieve tube 1.
and water is put in the water tank 11, and the water surface 18 is the drain port 1.
When the height reaches 2, the sieve tube 1 is rotated in the direction of the arrow and fresh concrete, sandstone, etc. are poured in together with water from the inlet 16.

To explain the case of separation of fresh concrete, the poured fresh concrete is separated from the auxiliary tube 4 of the sieve tube 1.
It slides down the inner periphery of the concrete and enters below the water surface 18 of the rear cylinder 2, where the cement is dissolved in water, so the ready-mixed concrete is separated into stones, sand, and water in which the cement has been dissolved.

The cement-dissolved water is then discharged from the drain port 12 at the rear end of the water tank 11, and the sand 15 is deposited in the gap between the round bars 2a forming the rear tube 2 of the sieve tube 1 and on the outer circumferential surface of the front tube 3. The stones 17 are sieved through the small holes 6 provided and fall to the bottom of the water tank 11, leaving the stones 17 in the sieve tube 1.

Next, the sand 15 that has fallen to the bottom of the water tank 11 is removed by the outer spiral blade 8.
The water is sent in the direction of the opening at the front end of the water tank 11, and when it comes to the front of the partition 14 where the water is drained above the water surface 18, it is lifted upward by the bent part 10 of the outer spiral blade 8 and further The water is drained and collected over the partition 14.

On the other hand, the stones 17 left in the sieve tube 1 are sent toward the opening at the front end of the sieve tube 1, drained of water above the water surface 18, and then collected from the opening.

In this way, the ready-mixed concrete is continuously separated into six parts, sand and cement-dissolved water, and each is recovered.

In the case of sand and stone, it is separated into stone, sand, and water containing dissolved impurities.

As explained above, according to the separator for ready-mixed concrete, sandstone, etc. of the present invention, it is possible to easily and efficiently collect ready-mixed concrete that is left behind or is no longer needed, thereby wasting expensive aggregate. It can be reused without being destroyed, and stones and sand can be easily and efficiently separated from sand and stones collected from riverbeds, etc.

In particular, fresh concrete, sand and stones, etc. are charged into the sieve tube from the rear of the sieve tube, and the separated sand and stones are collected from the front of the sieve tube. The opening of the cylinder can be made larger, which allows the loading position to be lowered and the operation of loading ready-mixed concrete, sandstone, etc. to be made easier.

Since the separated sand and stones are collected from the front of the sieve tube as described above, the separation and collection section for sand and stones is also used, and the overall length of the separator can be shortened.

Next, by forming the rear cylinder of the sieve tube by arranging round rods in a cylindrical shape with appropriate gaps, it is possible to improve the efficiency of the sieve, and it is difficult to clog. However, it can be easily removed.

Finally, with the configuration of the invention described in claim 2, sand can be drained effectively over a short distance and in a short time.
