[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a cement dust collection device for pipe pile production, including an exhaust fan 1. The exhaust fan 1's outlet is connected to an external dust removal pipe for conveying dust-laden air to a collection box 2. The collection box 2 is installed at the bottom of the exhaust fan 1. The air inlet of the exhaust fan 1 and the collection outlet of the collection box 2 are connected by a flange to ensure the sealing of the connection and prevent dust leakage. An opening is provided at the bottom of the exhaust fan 1, and a collection port is provided through the cover plate 3. The exhaust fan 1 is connected to the collection port through the opening. The collection box 2 is a rectangular box with openings at both the top and bottom. The bottom opening of the collection box 2 is connected to... The hopper has a discharge hopper with a slot on one side. A baffle is inserted into the slot. The discharge hopper has an inverted conical structure with the cone angle designed to facilitate dust sliding. The slot is used to insert the baffle to control the discharge process. The baffle can completely seal the discharge hopper outlet. The filter screen 4 is bolted to the inner wall of the collection box 2. The top of the collection box 2 is threaded with a cover plate 3. The filter screen 4 is installed inside the collection box 2. A water supply pipe 6 is installed at the top opening of the collection box 2. The water supply pipe 6 is connected to an external water source through a flange. A ring of nozzles 7 is connected to the water supply pipe 6. The water supply pipe 6 is a rectangular, looping tube with a ring of water supply holes. The nozzle 7 is connected to the water inlet at its top and is located above the filter screen 4. The nozzle 7 is a conical nozzle, and its spray angle covers the entire upper surface of the filter screen 4 for cleaning dust. A slot is provided on one side of the outer wall of the collection box 2, and a cleaning component 5 is inserted into the inner wall of the slot. The cleaning component 5 includes a bracket 501, one end of which is rotatably connected to a rotating shaft 502. A cleaning brush 503 is installed on one side of the rotating shaft 502. The bracket 501 is U-shaped. Sliding grooves are provided on opposite sides of the inner wall of the collection box 2. The two extended ends of the U-shaped rod of the bracket 501 slide within the sliding grooves for cleaning. The extension end of the bracket 501 of component 5 is fitted with the groove on the inner wall of the collection box 2, allowing it to slide along the groove. Both ends of the cleaning brush 503 are rotatably connected to the rotating shaft 502. The two rotating shafts 502 are respectively rotatably connected to the opposite sides of the extension end. The cleaning brush 503 can rotate freely around the rotating shaft 502 to adapt to the surface shape of the filter screen 4. The bottom surface of the cleaning brush 503 is set against the top surface of the filter screen 4. After the cleaning component 5 is inserted into the slot, pulling the bracket 501 will move the cleaning brush 503 on the filter screen 4 to the designated position, thereby cleaning the filter screen 4. The exhaust fan 1 mentioned above is existing technology and will not be described in detail.

[0021] First, connect the power supply to the electrical equipment in this device, place the device in the designated working position, and after the exhaust fan 1 is started, the dust-laden air generated during the pipe pile production is transported to the collection box 2 through the air outlet. The falling dust is filtered by the filter screen 4, and larger dust particles are intercepted on the filter screen 4. The purified air is discharged through the air inlet of the exhaust fan 1. After the dust collection is completed, the dust on the surface of the filter screen 4 increases. At this time, pull the bracket 501 of the cleaning component 5 to move the cleaning brush 503 on the filter screen 4 to collect the dust together, so as to facilitate the separate collection of larger dust particles. When it is necessary to clean the filter screen 4, the external water source sprays the filter screen 4 through the water supply pipe 6 and the nozzle 7. The dust scraped off and washed off accumulates in the unloading hopper, and the unloading can be controlled by pulling out the baffle.
