Description

Technical Field

[0001] The utility model relates to a dust recovery device, in particular to a dust recovery device for producing heavy calcium carbonate, belonging to the technical field of dust recovery devices. Background Art

[0002] Heavy calcium carbonate, abbreviated as heavy calcium carbonate, is made by grinding natural carbonate minerals such as calcite, marble, and limestone. A large amount of dust will be generated during the production process of heavy calcium carbonate. These dusts will drift into the air and will not only cause air pollution, but also cause waste of materials. Therefore, it is necessary to use a dust recovery device to recover the heavy calcium carbonate dust. Generally, the dust will be recovered and processed through a bag dust collector. The bag dust collector will collect dust through the dust hopper at its bottom. As the use time of the dust hopper increases, a certain amount of dust blocks will be compacted on its inner wall. The dust blocks that are compacted inside the dust hopper for a long time are easy to cause corrosion to the dust hopper. Therefore, in order to ensure the service life of the dust hopper, the compacted dust blocks inside the dust hopper need to be cleaned regularly.

[0003] However, most traditional dust hoppers are installed at the bottom of the bag filter by multiple bolts. Therefore, every time the inside of the dust hopper needs to be cleaned, it is necessary to use a wrench of a specific specification to twist multiple bolts to disassemble the dust hopper, which wastes a lot of time. At the same time, the operation is not convenient, making it inconvenient to clean and repair the dust hopper. Utility Model Content

[0004] The purpose of the utility model is to provide a dust recovery device for heavy calcium carbonate production in order to solve the above problems, which can facilitate the disassembly of the dust hopper, thereby facilitating the cleaning and maintenance of the dust hopper.

[0012] Preferably, the support frame is in a U-shaped structure, and the axis of the connecting shaft and the axis of the screw rod are on the same straight line.

[0013] The beneficial effect of the present invention is that when the interior of the ash hopper needs to be cleaned, the fixed structure can quickly release the fixation of the ash hopper, and then the two first motors can be started at the same time, and the output shafts of the two first motors rotate to drive the rotating shaft to rotate, the rotation of the rotating shaft drives the connecting seat to rotate, the rotation of the connecting seat drives the slide to rotate, and the rotation of the slide drives the ash hopper to rotate away from the bag dust collector body. After the ash hopper rotates ninety degrees, the output shafts of the two first motors stop rotating at the same time. At this time, the interior of the ash hopper will be exposed to the external environment, so the interior of the ash hopper can be cleaned next. Since there is no need to use a wrench of a specific specification to twist multiple bolts one by one to achieve the disassembly of the ash hopper in this process, it not only shortens the operation time, but also improves the convenience of operation, thereby facilitating the cleaning and maintenance of the ash hopper.

Therefore, by removing the cover plate 8 from the top of the bag dust collector body 1, it is convenient to inspect and maintain the interior.

[0025] As a technical optimization solution of the utility model, Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the fixed structure 5 includes a second motor 501 and a screw rod 502. Four second motors 501 are installed on the bag dust collector body 1. Four screw rods 502 are rotatably connected to the bag dust collector body 1. One end of the screw rod 502 is fixedly connected to the output shaft of the second motor 501. Four support frames 503 are fixedly connected to the bag dust collector body 1.
