Technical Field
[0001] This utility model relates to the field of solid waste treatment equipment technology, and more specifically, to a dust removal device for solid waste treatment equipment. Background Technology
[0002] Fly ash, desulfurized gypsum, construction waste, and slag are all recyclable solid wastes. Solid waste treatment requires breaking large pieces of material into smaller pieces and then grinding them into powder for easy recycling. Conveyors are typically used to transport solid waste materials to the inlet of crushing and grinding equipment. To prevent dust from being generated when solid waste falls into the equipment, dust removal devices are required.
[0003] In the prior art, such as the document with announcement number CN220257539U, a dust removal device for solid waste treatment equipment is specifically disclosed. In this document, the device uses an induced draft fan installed above the conveyor and the feed inlet to adsorb dust upwards, and spray nozzles installed on both sides of the feed inlet to suppress dust. Although it can achieve a certain degree of dust removal effect, in actual application, when solid waste is poured into the feed inlet of the equipment, the air inside the feed inlet is compressed instantly, causing the air inside the equipment to rise sharply, thereby generating dust agitation. At this time, even with the treatment of the induced draft fan and spray nozzles, it is difficult to effectively prevent the dust from spreading into the outside air and affecting the production environment. Utility Model Content
[0004] Based on the aforementioned technical problem that when solid waste is poured into the feed inlet of the equipment, the air inside the feed inlet is compressed instantly, causing the air inside the equipment to rise sharply, resulting in dust being agitated. Even with the help of a blower and spray nozzles, it is difficult to effectively prevent the dust from spreading into the outside air and affecting the production environment, this utility model proposes a dust removal device for solid waste treatment equipment.
[0005] The present invention provides a dust removal device for solid waste treatment equipment, comprising a sealed box, a conveyor and an exhaust assembly. An installation box is installed on the top of the sealed box, the exhaust assembly is installed on the installation box, and the end of the conveyor extends into the sealed box.
[0006] The exhaust assembly includes a second motor, a second base is fixedly connected to the base of the second motor, the second base is fixedly installed on the top of the mounting box, a drive shaft is fixedly connected to the output end of the second motor, the end of the drive shaft passes through the mounting box and is rotatably connected to it, and fan blades are fixedly connected to the outer wall of the drive shaft.
[0007] Preferably, a hopper is fixedly connected to the bottom of the sealed box, and a cover plate is fixedly connected to the outer wall of the sealed box, with the bottom of the cover plate contacting the top of the conveyor.
[0008] Preferably, the inner wall of the mounting box has a first mounting cavity, a second mounting cavity, and a third mounting cavity, and the fan blade is located in the second mounting cavity.
[0009] Preferably, an unwinding shaft is rotatably connected to the inner wall of the first mounting cavity, and a winding shaft is rotatably connected to the inner wall of the third mounting cavity. A second synchronous pulley is fixedly connected to the outer wall of both the unwinding shaft and the winding shaft. The two second synchronous pulleys are connected by a synchronous belt drive. A filter screen is fixedly connected to the outer wall of the unwinding shaft, and the end of the filter screen is fixedly connected to the winding shaft.
[0010] Preferably, a first base is fixedly connected to the outer wall of the mounting box, a first motor is fixedly connected to the top of the first base, and the output end of the first motor is fixedly connected to the take-up shaft.
[0011] Preferably, limiting grooves are formed on both sides of the inner wall of the second mounting cavity, and the two sides of the filter screen are slidably connected to the inner wall of the limiting grooves respectively.
[0012] Preferably, a box is fixedly connected to the inner wall of the third mounting cavity, a connecting shaft is rotatably connected to the inner wall of the box, a cleaning brush is fixedly connected to the outer wall of the connecting shaft, the cleaning brush is in frictional contact with the filter screen, and a first synchronous pulley is fixedly connected to the outer wall of both the connecting shaft and the winding shaft, and the two first synchronous pulleys are connected by a synchronous belt drive.
[0013] Preferably, a vacuum cleaner is fixedly connected to the top of the mounting box, and a suction tube is fixedly connected to the suction end of the vacuum cleaner, with the end of the suction tube extending into the box.
[0014] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:
[0015] 1. The sealed box design prevents dust from being stirred up by solid waste during its descent from spreading into the outside air, thus protecting the working environment. The second motor drives the fan blades to rotate via the drive shaft, creating internal airflow and further reducing dust diffusion.
[0016] 2. The cover plate can form a channel with the conveyor to prevent dust exposed in the sealed box from being instantly discharged into the outside air through the holes at the conveyor. The exposed dust spreads in the channel, and the airflow generated by the rotation of the fan blades will draw the dust in the channel into the installation box.
[0017] 3. The first motor drives the unwinding shaft and the rewinding shaft to rotate simultaneously, thereby causing the filter screen to slide along the inner wall of the limiting groove, thus keeping the filter holes on the filter screen unobstructed, improving the filtration effect, and ensuring the continuity of airflow.
[0018] 4. When the filter moves, the first motor drives the connecting shaft to rotate through the first synchronous wheel, which in turn drives the cleaning brush to rotate, thereby cleaning the dust clogging the surface of the filter. The vacuum cleaner then absorbs the loosened dust through the suction tube, achieving automatic cleaning. Attached Figure Description

[0028] like Figure 1 As shown, a hopper 2 is fixedly connected to the bottom of the sealing box 1, and a cover plate 4 is fixedly connected to the outer wall of the sealing box 1. The bottom of the cover plate 4 is in contact with the top of the conveyor 3.
[0029] like Figure 2 and 4 As shown, the inner wall of the mounting box 5 has a first mounting cavity 6, a second mounting cavity 7 and a third mounting cavity 9, and the fan blade 17 is located in the second mounting cavity 7.
[0030] like Figure 2 and Figure 3 As shown, an unwinding shaft 10 is rotatably connected to the inner wall of the first mounting cavity 6, and a winding shaft 11 is rotatably connected to the inner wall of the third mounting cavity 9. Second synchronous pulleys 25 are fixedly connected to the outer walls of both the unwinding shaft 10 and the winding shaft 11. The two second synchronous pulleys 25 are connected by a synchronous belt drive. A filter screen 24 is fixedly connected to the outer wall of the unwinding shaft 10, and the end of the filter screen 24 is fixedly connected to the winding shaft 11. The filter screen 24 is used to filter dust in the discharged gas, preventing dust from being directly discharged into the environment. The filter screen is unfolded and rolled up via the unwinding shaft 10 and the winding shaft 11, facilitating replacement and cleaning.
[0031] like Figure 3 and Figure 4 As shown, a first base 12 is fixedly connected to the outer wall of the mounting box 5, a first motor 13 is fixedly connected to the top of the first base 12, and the output end of the first motor 13 is fixedly connected to the take-up shaft 11.

The filtered air is discharged from the air hole at the top of the mounting box 5.
[0035] The cover plate 4 can form a channel with the conveyor 3 to prevent the dust exposed in the sealed box 1 from being instantly discharged into the outside air through the hole at the conveyor 3. The exposed dust spreads in the channel, and at this time, the airflow generated by the rotation of the fan blade 17 will draw the dust in the channel into the mounting box 5.
[0036] The first motor 13 drives the unwinding shaft 10 and the take-up shaft 11 to rotate simultaneously, thereby causing the filter screen 24 to slide along the inner wall of the limiting groove 8, thus keeping the filter holes on the filter screen 24 unobstructed and improving the filtration effect.
[0037] When the filter 24 moves, the first motor 13 drives the connecting shaft 19 to rotate through the first synchronous wheel 21, and drives the cleaning brush 20 to rotate through the connecting shaft 19, thereby cleaning the dust clogging the surface of the filter 24. The vacuum cleaner 22 absorbs the dust that falls off through the suction tube 23.
