Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure dust removal, in particular to a novel negative pressure dust removal device. Background Art

[0002] During the feed processing, dust will be generated in the unloading, crushing, mixing, screening, packaging, and the poor sealing of the preparation and conveying pipelines, which will lead to the leakage of materials. Dust is a very important factor of loss, and dust explosions account for 48% of accidents in compound feed factories. Effective control of dust generation and dust removal are very important for feed production management and control. Currently, there are many kinds of dust removal equipment, but the actual dust removal effect is not ideal, the operation is cumbersome, and the efficiency is low. Therefore, better negative pressure dust removal devices are needed to remove dust from the workshop.

[0003] For example, a new type of workshop dust removal negative pressure device with announcement number CN210497582U includes a wind suction main body. The new type of workshop dust removal negative pressure device is provided with a locking bolt. In daily use, the two locking bolts on the outside of the net ring are separated so that the net ring is taken out from between the two locking bolts, and the filter can be taken out from the inside of the filter slot for cleaning to prevent clogging caused by excessive dust;

[0004] This new type of workshop dust removal negative pressure device is to disassemble and clean the filter by setting a locking bolt at the mesh circle, but this disassembly and cleaning method is not only time-consuming and labor-intensive, but also the equipment needs to be shut down and cannot be used during the stage of disassembling and cleaning the filter, thereby reducing the use effect. At the same time, the above-mentioned method uses a fixed block and a fixed spring to tightly fix the filter element and the core barrel, but because the dust removal negative pressure device will generate a certain vibration when working, the spring is easily shaken by the vibration, thereby reducing the stability of the upper filter element and the core barrel. Therefore, it is urgent to solve the problem of fast and efficient dust removal in production to facilitate air purification, production safety, and improve the hygiene and safety of feed processing to improve feed quality. Utility Model Content

At the same time, since the dust removal negative pressure device will generate certain vibrations when working, the spring is easily shaken by the influence of the vibration, thereby reducing the stability of the upper filter element and the core barrel.

[0010] Preferably, the dust removal mechanism includes a horizontal plate fixedly connected to the middle inner wall of the dust collector housing, a filter element is attached to the upper surface of the horizontal plate, a pair of pressure plates are attached to the upper surface of the filter element, and the outer wall of the pressure plate is gap-matched with the inner wall of the slide groove of the dust collector housing, a second screw is rotatably connected above the pressure plate, and the outer wall of the second screw is connected to the internal thread of the dust collector housing, and a handle is fixed to the upper surface of the second screw.

[0011] Preferably, a fan is fixedly connected to the upper right side of the bottom plate, an air duct is fixedly connected to the air intake of the fan, and the other end of the air duct is connected to the interior of the dust collector housing.

[0012] Beneficial Effects

[0013] The utility model provides a new type of negative pressure dust removal device, which has the following beneficial effects:

[0014] When the filter screen needs to be cleaned, the motor can be started so that the output shaft of the motor drives the first screw to rotate back and forth regularly, and the first screw cooperates with the cross bar to drive the vertical plate to move, so that the vertical plate can drive the cleaning brush to move, so that the filter screen does not need to be disassembled to clean it, which is not only simpler and more convenient, reduces the labor level, but also does not need to stop the machine, so the use effect is better;

[0015] The filter element can be installed between the air collecting hood and the horizontal plate, and then the handle is turned to drive the second screw to rotate, so that the second screw drives the pressure plate to move through the dust collector housing, so that the pressure plate cooperates with the horizontal plate to fix the filter element tightly, and finally the box plate is fixed to the dust collector housing by bolts. Conversely, it is also convenient to disassemble and replace the filter element, so that the filter element is not easy to shake due to the vibration of the device during operation, and the stability is higher;

[0016] After that, the feed pipe is connected to several hoses through a joint, and they are arranged on each floor of the feed factory processing workshop and connected to the clean area on site. In this way, when the fan is started, negative pressure is generated at the air duct of the fan. Under the action of negative pressure, the various hoses on site can suck in the dust and discharge it into the shaker through the feed pipe. The coarse powder in the dust is filtered by the shaker, and the fine powder is discharged into the dust collector shell through the guide pipe and the air collecting hood, and filtered through the filter element and the filter screen in turn. In this way, the dust is sucked in by negative pressure, which improves the previous method of using positive pressure blowing or simple cleaning, which will lift the dust and then let it stand and settle again, or cause dust overflow and environmental pollution. At the same time, the dust can be gathered, recycled and reused to reduce resource waste and reduce losses. BRIEF DESCRIPTION OF THE DRAWINGS
