Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a pretreatment device for removing impurities from building solid waste. Background Technology

[0002] Construction solid waste refers to solid waste generated during the construction, maintenance, and demolition of buildings, such as waste concrete blocks, brick and stone fragments, and slag. With the rapid development of urban construction, the amount of construction solid waste generated is increasing day by day. In order to achieve resource recycling and environmental protection, construction solid waste needs to be pre-treated. Screening is a key step in the pre-treatment of construction solid waste, which can separate solid waste of different particle sizes. However, the screening process generates a lot of smoke and dust, which not only pollutes the environment but also endangers the health of operators.

[0003] Currently, dust collection equipment is commonly used to collect smoke and dust and prevent its spread. At the same time, filter plates are used to filter large particles such as dust from the smoke and dust. However, after prolonged use, a large amount of dust and other large particles accumulate on the filter plates. Existing pretreatment equipment is unable to effectively clean the filter plates, which will lead to filter plate blockage, reduce dust collection efficiency, and worsen the smoke and dust purification effect. A large amount of unpurified smoke and dust will be emitted into the air, further aggravating environmental pollution. It may also affect the normal operation and service life of the equipment and increase equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a pretreatment device for removing impurities from construction solid waste. It includes a cleaning component. Specifically, when excessive dust accumulates on the filter plate and cleaning is required, a motor is activated to drive a reciprocating screw to rotate, which in turn moves an internal threaded block. This internal threaded block then drives a brush to clean the surface of the filter plate. Simultaneously, a limiting block slides on a limiting rod to ensure stable brush movement. This effectively prevents dust from clogging the filter plate pores, maintains the suction power and filtration efficiency of the dust collection equipment, avoids decreased dust collection efficiency and increased energy consumption due to filter plate clogging, reduces secondary dust emissions, prevents filter plate wear and corrosion due to dust accumulation, extends the filter plate's service life, and reduces maintenance costs. This invention solves the problem of existing pretreatment equipment's difficulty in effectively cleaning filter plates.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0015] A drive assembly is installed outside the dust collection section and is used to enhance the screening effect of the screening assembly.

[0016] Among them, the screening component is changed from static screening to dynamic screening by the driving component, thereby improving the screening effect of the screening component.

[0017] Furthermore, the dust collection assembly includes a screening box, a top cover is installed on the top of the screening box, a connecting pipe passes through the top of the top cover, the connecting pipe is fixedly connected to the top cover, a dust suction hood is fixedly connected to the bottom end of the connecting pipe, and a filter plate is installed on the inner wall of the dust suction hood.

[0021] Furthermore, the limiting component includes a limiting rod fixedly connected to the inner wall of the top cover, a limiting block slidably connected to the outer wall of the limiting rod, and the limiting block fixedly connected to the brush.

[0022] The limiting rod is fixedly connected to the inner wall of the top cover by welding.

[0023] Furthermore, the screening assembly includes a screening drum rotatably connected to the inner wall of the screening box, the right end of the screening drum extending to the outside of the screening box, a feed hopper penetrating the left side of the top cover, the feed hopper being fixedly connected to the screening box, the right side of the feed hopper extending to the inside of the screening drum, a discharge port being provided at the bottom of the screening box, a discharge pipe being fixedly connected to the outer wall of the screening drum, and a valve being fixedly connected to the outer wall of the discharge pipe;

[0029] 2. By setting up a screening section, specifically during the pretreatment of solid waste, the second drive shaft of the motor drives the gear to rotate, and the ring rack causes the screening drum to rotate, realizing dynamic screening. This allows the material to tumble fully inside the drum, enabling more efficient and precise separation of impurities of different particle sizes. Impurities that meet the particle size requirements are discharged through the screen holes and the discharge port, while materials that do not pass through are temporarily stored and discharged through the discharge pipe for further processing. This greatly improves screening efficiency and quality, ensures the pretreatment effect of construction solid waste, and provides high-quality raw materials for subsequent resource utilization.

The gear 223 meshes with the ring rack 224.

[0060] The annular rack 224 is fixedly connected to the screening drum 211 by welding.

[0061] A specific application of this embodiment is as follows: When using this device, firstly, solid waste impurities enter the screening drum 211 through the feed hopper 212. Then, the second motor 221 is started, and the second motor 221 drives the rotating shaft 222 to drive the gear 223 to rotate. Through the meshing ring rack 224, the screening drum 211 is rotated to achieve dynamic screening. When the material tumbles in the drum, impurities that meet the particle size requirements fall into the bottom of the screening box 111 through the screen holes and are discharged through the discharge port 213. The material that does not pass through is temporarily stored in the drum. After screening is completed, the valve 215 outside the discharge pipe 214 is opened so that the material that does not pass through the screening is discharged through the discharge pipe 214 and falls into the interior of the screening box 111. Finally, it is discharged through the discharge port 213 at the bottom of the screening box 111.

[0062] Simultaneously, the connecting pipe 113 is connected to an external dust collection device, so that the dust generated during the screening process is sucked into the dust collection device by the dust hood 114 through the connecting pipe 113 for collection. The dust is filtered through the filter plate 115, and large particles such as dust in the dust are trapped. The purified air is discharged. To maintain the filtration effect of the filter plate 115, the motor 121 is started. The motor 121 drives the reciprocating screw 122 to rotate. When the reciprocating screw 122 rotates, it drives the internal thread block 123 to move. When the internal thread block 123 moves, it drives the brush 124 to move, thereby cleaning the surface of the filter plate 115 through the brush 124. At the same time, when the brush 124 moves, it drives the limiting block 132 to slide on the limiting rod 131. The limiting rod 131 and the limiting block 132 make the movement of the brush 124 more stable, and at the same time prevent the brush 124 and the internal thread block 123 from rotating with the rotation of the reciprocating screw 122.
