Description

[Detailed Description of the Invention] Purpose of the Invention The present invention relates to a discharging device for powder, granules, chips, etc., and an object of the present invention is to promote the unscrupulous discharge of powder, granules, chips, etc. that are easily crosslinked in a storage tank. The purpose is to reduce power consumption by increasing discharge efficiency and reducing the driving torque required to discharge powder, granules, chips, etc.

Prior art A conventional powder discharge device is a device in which a rotating blade is installed in a can body connected to the bottom of a storage tank, and the powder is discharged by rotating this rotating blade with an electric motor. Therefore, the load resistance due to the weight of the powder and granules in the storage tank and the load resistance of rotating the rotary blades in the powder and granules are very large, and therefore an electric motor with a large driving torque must be used, which causes problems in the equipment. As prices rose, power consumption increased.

In addition, the powder and granules tend to be compacted by their own weight in the storage tank, making it impossible to discharge them smoothly and resulting in low discharge efficiency.

Structure of the Invention The present invention is designed to discharge the powder, granules, chips, etc. that are filled in a storage tank by cutting the lowest part of the powder, granules, chips, etc., using a chainsaw-like rotating blade and transporting them to the discharge port. , Examples will be described below.

In Figures 1 and 2, a can body 2 with a larger diameter than the storage tank 1 is located at the bottom of a storage tank 1 that stores a large amount of powder, granules, chips, etc.
are installed in succession.

This can body 2 is provided with a gap A between the lower end 1a of the storage tank 1 and the bottom plate 3, which is necessary for the outflow of powder, granules, chips, etc.
There are discharge ports 4 at several locations on the outer periphery of the bottom plate j, and a discharge port 5 in the center.
is opened.

A motor 6 is provided at the discharge port 5 in the center, and a sprocket T is attached to the shaft end of the motor 6.

8 is a motor cover, which collects powder and granules discharged from the discharge port 5;
The motor 6 is protected from being touched by chips and the like.

The rotating wheels 9, which are rotatably installed inside the can body 2, have a larger diameter than the storage tank 1, and are arranged radially on the inner circumferential surface thereof at approximately equal intervals in the circumferential direction, with their tips close to the lower end of the storage tank 1. Many scraping boards 1
Further, a scraping blade 11 whose tip reaches inward into the storage tank 1 is fixed to the lower end of the rotary ring 9.

Three ring plates 12 are fitted and fixed to the outer peripheral surface of the rotating ring 9 at required intervals vertically, and a large number of pins 13 are fitted and fixed to the ring plates 12 at equal intervals in the circumferential direction over the entire circumference. It is formed into a pin gear shape and can be engaged with a gear 14, which will be described later.

A pair of brackets 15 are fixed on the upper and lower sides inside the rotating ring 9, a vertical shaft 16 is rotatably supported in the vertical direction by the brackets 15, and a sprocket 17 is attached to the lower end of the vertical shaft 16.

A large number of guide rollers 19 are rotatably supported at approximately equal intervals on the outside of the rotating ring 9 in the can body 2, the axes of which are oriented vertically, and each of which has a flange 18 at its lower end. 12 are in contact with each other, the flange 18 receives the lowest ring plate 12, and the rotary ring 9 is provided so as to be able to rotate without contacting the bottom plate 3.

A gear 14 that engages with the pin 13 is attached to a drive shaft 20 that is rotatably supported outside the rotating ring 9 inside the can body 2 with its axis facing vertically. The electric motor 21 installed in the

An endless chainsaw-like rotating blade 22 is hung between the sprocket 7 and the sprocket 17.

The chainsaw-like rotary blade 22 may be a chain saw or a roller chain with a blade body having a cutting edge fixed thereto.

Function of the Invention To explain the function of the discharge device of the present invention, the motor 2
When the gear 14 is started, the gear 14 rotates, and the rotary wheel 9, which is engaged with the gear 14 and formed in the shape of a pin gear, continuously rotates in the direction of arrow R.

On the other hand, by starting the motor 6, the chainsaw-like rotary blade 22
runs continuously in the direction of arrow Q.

The powder, granules, chips, etc. stored in the storage tank 1 are compacted and solidified by their own weight, and will not easily flow out naturally from the gap A between the storage tank 1 and the bottom plate 3, but due to the rotation of the rotating wheel 9. At the same time, the chainsaw-like rotary blade 22 cuts down the compacted powder, chips, etc., and on the front side in the direction of rotation moves the broken powder, chips, etc. to the central discharge port 5, and on the rear side. Then, move it to the discharge chamber 23.

Powder loosened by a chainsaw-like rotating blade 22,
Chips and the like naturally flow out from the gap A into the discharge chamber 23, are further carried to the discharge port 14 by the scraper plate 10, and are discharged from the discharge port 4.

The raking blades 11 are used to promote the outflow from the gap A to the discharge chamber 23, and do not need to be provided.

Effects of the Invention The present invention provides a rotary ring rotatably in the can body connected to the lower part of the storage tank, and a large number of scraping plates are fixed to the inner peripheral surface of the rotary ring. The structure is such that a sprocket is attached to a rotatably supported vertical shaft, the sprocket is attached to the shaft end of a motor installed at the outlet in the center of the bottom plate, and a chainsaw-like rotating blade is hung between both sprockets. Powder, granules, chips, etc. that have been filled and compacted are broken down by a chainsaw-like rotating blade, making it easier for them to flow naturally into the discharge chamber. The emission efficiency increases as the waste is transported up to

Furthermore, since the chainsaw-like rotary blade may be thin, there is less resistance due to the weight of powder, chips, etc., and the drive torque is reduced, so it is highly effective in reducing power consumption.
