[0002] Plastic barrels are mostly used for the storage and transportation of various liquids, and have good characteristics for the packaging of special dangerous goods. They are not easy to break, do not rust, are light in weight, etc., and have excellent oil resistance and strong corrosion resistance. They are mostly used for the packaging of dangerous goods that require heat preservation, moisture protection, pressure resistance, and corrosion resistance. The materials of plastic barrels are mostly made of polyethylene, polypropylene, polyester, etc. by blow molding, injection molding, thermoforming, and rotational molding, and are mostly used for containing liquid and solid items in industries such as chemical industry, pesticides, medicine, food, hardware electronics, and mechanical and electrical.

[0003] In the utility model patent named a raw material screening device for the production of food plastic barrels (application number 202220825616.2), it is proposed that "the utility model relates to the technical field of the production of food plastic barrels, and particularly is a raw material screening device for the production of food plastic barrels, including a device housing, a feeding port is opened at the top end of the device housing, a coarse separation component and a fine separation component are arranged inside the device housing, the coarse separation component includes a sieve plate arranged inside the device housing, and a triangular plate is fixedly installed at the central axis of the inner bottom of the sieve plate, a uniformly distributed sieve hole is opened on one side of the inner bottom of the sieve plate, the fine separation component includes a vibrating sieve plate hinged to the inner wall of one side of the device housing; in the actual screening process of the utility model by using the arranged driving component, the rotation motor can be controlled to start, the rotation motor drives the turntable to rotate through the driving column, so that the extension column makes a circular motion, and with the arranged through hole, the swing arm drives the sieve plate to swing reciprocally with the rotating shaft as the center, so that the materials can be turned over inside the sieve plate, which is beneficial to improving the screening effect of the materials." However, the utility model patent has the following problems:

[0004] 1. In this application, it is not considered that the cleaning of the set filter box is relatively inconvenient, and such a treatment method is not good. It can only rely on manual cleaning, which is too labor-consuming.

[0005] 2. In this application, the dust extraction fan is installed at the lower part of the filter box and is directly connected by a pipeline, without considering the situation that dust flows back into the dust extraction fan when the dust extraction fan stops running.

[0026] Working principle description:

[0027] The basic function of this device is the same as that of the utility model patent named "A raw material screening device for the production of food plastic barrels" (application number 202220825616.2). The device screens the raw materials for plastic barrel production through the screening device main body 1, discharges the qualified raw materials through the discharge port 2, and extracts the dust from the dust extraction main pipe 3 by the dust extraction fan 4. It should be noted that when the dust extraction fan 4 is working, first, the dust is drawn into the filter box 5 through the dust extraction main pipe 3. After being filtered by the filter screen 12, the clean gas is discharged through the dust extraction fan 4 by the exhaust pipe 7. Part of the dust filtered out by the filter screen 12 adheres to the filter screen 12, and part of it falls on the rotating plate 16. First, start the first motor 8 with the dust extraction fan 4 stopped. The power output end of the first motor 8 drives the reciprocating lead screw 9 to rotate. Therefore, the slider 11 moves back and forth in the chute 10. The movement of the slider 11 drives the brush body 13 to move, so that the brush body 13 cleans the filter screen 12. The dust cleaned out falls on the rotating plate 16. Then start the second motor 14. The power output end of the second motor 14 drives the rotating shaft 15 to rotate. Therefore, the rotating plate 16 rotates to discharge the dust into the waste box 6. When it is necessary to discharge the dust in the waste box 6, open the mechanical latch 18 and open the box door 17 to discharge the dust.

[0028] Preferably, a rubber cushion layer is installed in the chute 10. With such a structural design, the frictional damage to the chute 10 is reduced, and the service life of the device is prolonged.

[0029] Preferably, a sealing rubber strip is installed on the rotating plate 16. With such a structural design, the sealing effect of the rotating plate 16 is better, preventing dust from flowing back.

[0030] Preferably, a sealing rubber strip is installed on the box door 17. With such a structural design, the sealing effect of the box door 17 is better, preventing dust from leaking out.

[0031] Preferably, a rubber cushion layer is installed on the slider 11. With such a structural design, the frictional damage to the slider 11 is reduced, and the service life of the device is prolonged.

[0032] The above embodiments only exemplarily illustrate the principle and its effects of the present utility model, rather than being used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
