Description

Technical Field

[0001] The utility model relates to the technical field of expanded perlite production, and more particularly to a dust processing and collecting box for expanded perlite production. Background Art

[0002] Expanded perlite is a natural acidic glassy volcanic lava, a non-metallic mineral. It includes perlite, pitchstone, and obsidian, which differ only in their crystalline water content. Because its volume rapidly expands 4 to 30 times under high temperature conditions of 1000 to 1300°C, it is collectively referred to as expanded perlite.

[0003] It can be used as a filter, catalyst, molecular sieve, and carrier for rubber, fertilizers, and pesticides. It is widely used in construction, metallurgy, petroleum, machinery, light industry, hydropower, casting, medicine, food, agriculture, forestry, and horticulture.

[0004] During the production and processing of expanded perlite, it goes through many processes such as crushing and sintering, which will generate a lot of dust floating in the air. Therefore, the dust needs to be collected and processed. Most of the existing dust removal devices are connected and fixed together with the expanded perlite processing equipment. This results in a small range of dust collection and removal, and it is not possible to flexibly collect and process the dust floating in the air. Utility Model Content

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the utility model provides a dust treatment and collection box for expanded perlite production, which has the following beneficial effects:

[0019] 1. The utility model is provided with an arc-shaped filter structure, which can expand the filtering area of ​​the filter in the box body and improve the dust filtering effect of the expanded perlite in the production process. In this process, the air flow enters the box body from the air inlet pipe, and the dust therein is intercepted by the arc-shaped filter, and the excess air flow is discharged outward through the air outlet pipe, thereby realizing the dust processing and collection of the expanded perlite in the production process. The first motor is started, and the cleaning shaft can be controlled to rotate by the first motor. The scraper can be controlled to rotate by the cleaning shaft to scrape the lower surface of the arc-shaped filter, thereby achieving surface cleaning of the arc-shaped filter, thereby improving the filtering effect of the arc-shaped filter, avoiding the blockage of the arc-shaped filter, and improving the filtering effect of the arc-shaped filter.

[0020] 2. In the utility model, the dust intercepted in the box by the arc filter will fall under its own gravity and be collected at the bottom of the box and inside the dust exhaust pipe. When the collected dust needs to be discharged outward, the sealing cover is opened and the second motor is started. The second motor is used to control the rotation of the spiral conveying shaft, so that the dust impurities that have fallen into the dust exhaust pipe are discharged outward, thereby completing the cleaning of the collected dust. During this process, the water pump can be started to pump water out of the water tank through the water pump, and transported to the spray pipe through the liquid supply pipe, and sprayed out through the atomizing nozzle on the spray pipe, so that the dust can be sprayed and moistened during the process of being discharged from the dust exhaust pipe, thereby avoiding the situation of secondary dusting during discharge.

[0021] 3. The utility model sets a backflush pipe above the curved filter. In this way, when the curved filter needs to be further cleaned, the valve on the air outlet pipe is closed or partially closed, and the valve on the delivery pipe is opened, so that the air flow can be reversely delivered to the backflush pipe through the delivery pipe, so that the air flow is blown out in the opposite direction toward the curved filter, thereby sweeping away the dust impurities adhering to the surface of the curved filter, realizing a one-step cleaning of the curved filter, and ensuring the dust interception and filtration effect of the curved filter during the dust treatment process in the production of expanded perlite.
