Description

Technical Field

[0001] This utility model relates to the field of barite powder production technology, specifically to a barite powder dust suppression and conveying device. Background Technology

[0002] Barite powder is a powdered product obtained from natural mineral barite through processes such as crushing, grinding, washing, drying, and sieving. Its main chemical component is barium sulfate. When drilling oil or gas wells, barite powder is added to the drilling mud as a weighting agent to increase the density of the drilling mud.

[0003] In the production process of barite powder, the produced powder needs to be conveyed by a conveyor belt to facilitate material transfer. Since barite powder is a small-particle-size and dry solid powder, dust is usually generated during material transportation. Currently, the common dust suppression measure is water spraying. However, water spraying of barite powder has the problems mentioned in the authorization announcement number CN222573740U "A Barite Dust Suppression and Conveying Device". Water spraying not only increases the conveying burden, but the water-containing barite powder will also affect its subsequent use. Utility Model Content

[0004] This invention addresses the problem of dust generation during the transport of barite powder and the poor dust control effect of existing technologies by providing a barite powder dust suppression and transport device. This device can conveniently suppress dust generated during the transport of barite powder and can also collect the dust.

[0005] To solve the above problems, the technical solution of this utility model is: A barite powder dust suppression and conveying device includes a housing with a conveyor belt rotatably mounted inside it. It also includes a first annular belt and a second annular belt. The first annular belt is rotatably mounted inside the housing above the conveyor belt. Receiving holes are provided at the top and bottom of the first annular belt, and medium-efficiency filters are installed within these holes. An n-shaped plate is installed inside the first annular belt, detachably connected to the housing. An input end of the housing is connected to an exhaust fan inside the n-shaped plate. The second annular belt is rotatably mounted inside the housing above the first annular belt, rotating in the opposite direction to the first annular belt. Brush bristles are attached to the outer surface of the second annular belt, with the lower part of the brush bristles contacting the upper part of the outer surface of the first annular belt. The upper part of the left end opening of the housing is blocked by a baffle, and a dust collection component is provided at the right end of the housing. Dust cleaned by the brush bristles on the second annular belt from the medium-efficiency filter on the upper part of the first annular belt is collected by the dust collection component.

[0006] Furthermore, a rotating shaft 1 is rotatably provided between the left and right sides of the front and rear side plates of the housing, and a conveyor belt is fitted around both rotating shafts 1. Either rotating shaft 1 is driven to rotate by a motor 1. A rotating shaft 2 is rotatably connected to the front and rear side plates of the housing on the upper side of each rotating shaft 1. An annular belt 1 is fitted around both rotating shafts 2. Either rotating shaft 2 is driven to rotate by a motor 2. A rotating shaft 3 is rotatably connected to the front and rear side plates of the housing on the upper side of each rotating shaft 2. An annular belt 2 is fitted around both rotating shafts 3. Either rotating shaft 3 is driven to rotate by a motor 3.

[0007] Furthermore, the baffle is located on the left side of the first and second annular belts; the n-shaped plate is located between the two rotating shafts; a through hole is provided on the rear side plate of the housing behind the first annular belt, and a connecting plate is connected to the rear end of the n-shaped plate through the through hole. The connecting plate is detachably connected to the rear side plate of the housing and blocks the through hole. A horizontal plate is fixed to the front side plate of the housing inside the front end of the first annular belt, and the front end of the inner top of the n-shaped plate is supported by the horizontal plate.

[0008] Furthermore, HEPA filters are provided at intervals from front to back inside the n-shaped plate; the front end of the n-shaped plate is blocked by the front side plate of the housing, and the lower part of the inner ring surface of the annular belt slides in contact with the lower end of the n-shaped plate.

[0009] Furthermore, the dust collection component includes a box body and a cover plate. The box body has an opening at its right end. The upper part of the right end of the housing is connected to the box body. A ventilation hole is provided on the left side plate of the box body. The upper end of the ventilation hole is higher than the upper end of the second annular belt, and the lower end is lower than the upper end of the first annular belt. The cover plate is detachably connected to the box body and blocks the opening at the right end of the box body. Connecting plates extending into the box body are connected to the upper and lower parts of the left side of the cover plate. A mesh is connected between the left ends of the opposite sides of the two connecting plates. An exhaust fan is provided on the cover plate.

[0010] The beneficial effects of this utility model through the above technical solution are as follows: When the conveyor belt transports barite powder, the medium-efficiency filter at the lower part of the annular belt can block the dust that is driven upward by the exhaust fan, and the HEPA filter in the n-shaped plate can block the dust. As the annular belt moves to the medium-efficiency filter at the upper part of the annular belt, it is cleaned by the brush on the rotating annular belt. The cleaned dust can be collected by the dust collection parts on the left and right sides of the housing. Therefore, this invention can suppress dust from flying during the transport of barite powder and can collect the flying dust. At the same time, it avoids the medium-efficiency filter from becoming clogged due to dust blockage, thus improving the dust suppression effect. Attached Figure Description
