This invention proposes a dust discharge pipeline device for mineral processing that is easy to operate, saves time and labor, has a scientific and reasonable design, and a simple structure, possessing very broad application prospects. However, this patent has the following problems: Mineral processing workshops have large interior spaces, and simply using dust hoods has a limited suction range, making it difficult to completely cover the interior of the workshop, thus resulting in limited dust extraction and removal efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a dust discharge pipeline device for mineral processing, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust discharge pipeline device for mineral processing, comprising a main dust discharge pipeline, several conveying branch pipes fixedly connected to the lower part of the main dust discharge pipeline, a suction pipe connected to the lower end of each conveying branch pipe, a dust suction hood fixedly connected to the lower end of each suction pipe, a motor bracket fixedly connected inside the suction pipe, a dust suction motor fixedly connected to the motor bracket, blades fixedly connected to the output end of the dust suction motor, a bracket slidably installed inside the dust suction hood, a collection cup fixedly connected to the bracket, a filter frame provided inside the suction pipe, and a dust filter fixedly connected inside the filter frame.

[0006] Preferably, a first flange is fixedly connected to the lower end of the conveying pipe, and a second flange is fixedly connected to the upper end of the suction pipe, and the second flange and the first flange are fixedly connected by bolts.

[0007] Preferably, the outer wall of the main dust exhaust pipe is fixed with several retaining rings, and two fixing collars are symmetrically engaged in the retaining rings. The fixing collars have through holes near the two side edges, and fixing bolts are installed in the through holes.

[0008] Preferably, a lifting rod is fixedly connected to the upper fixing collar, and a fixing foot is fixedly connected to the lifting rod.

[0009] Preferably, the outer wall of the lower edge of the dust collection hood is provided with a threaded groove, and a threaded collar is threadedly installed on the threaded groove.

[0010] Preferably, a raised edge is fixedly connected to the underside of the threaded collar, and the raised edge cooperates with the bracket.

[0011] Preferably, the dust cover has a slot on its lower inner wall, and the bracket is slidably installed inside the slot.

[0012] Preferably, a support screw is fixed to the bottom of the collecting cup.

[0013] Preferably, a connector is fixedly connected to the bottom of the filter frame, and a threaded hole is provided at the lower end of the connector, which is threadedly engaged with the support screw.

[0014] Preferably, the bracket has through slots arranged in rows near the outer edge, the outer wall of the filter frame is fixed with a sealing ring, and the diameter of the filter frame is the same as the inner diameter of the suction tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By suspending the main dust exhaust pipe on the top of the mining processing plant, and connecting multiple suction pipes with internal dust extraction mechanisms below the main dust exhaust pipe, the dust inside the plant can be extracted using multiple suction pipes and then discharged through the main dust exhaust pipe, resulting in better dust extraction and discharge.

[0016] 2. By using fixed feet and pins, the hanger can be fixed to the top of the factory building, and then the main dust exhaust pipe can be suspended from the top of the factory building.

[0017] 3. The filter frame is set inside the suction pipe. The dust filter can perform preliminary filtration of dust, preventing large dust particles from being sucked into the device and accumulating inside the pipe, which is difficult to clean. At the same time, it reduces the pressure of subsequent dust treatment.

[0018] 4. By using a dust filter, larger dust particles can be intercepted. The dust will adhere to the surface of the dust filter due to suction. When the machine stops, the large dust particles lose suction and will fall directly into the collection cup due to gravity, thus preventing the particles adhering to the surface of the dust filter from floating back into the factory due to machine shutdown.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-6 As shown, the present invention has the following specific embodiments.

[0023] Example 1 A dust discharge pipeline device for mineral processing includes a main dust discharge pipeline 1, with several conveying branch pipes 101 fixedly connected to the bottom of the main dust discharge pipeline 1. The lower end of each conveying branch pipe 101 is connected to a suction pipe 3, and the lower end of the suction pipe 3 is fixedly connected to a dust suction hood 302. A motor bracket 304 is fixedly connected inside the suction pipe 3, and a dust suction motor 305 is fixedly connected to the motor bracket 304. A blade 306 is fixedly connected to the output end of the dust suction motor 305. A bracket 4 is slidably installed inside the dust suction hood 302, and a collection cup 401 is fixedly connected to the bracket 4. A filter frame 5 is provided inside the suction pipe 3, and a dust filter 501 is fixedly connected inside the filter frame 5.

[0024] In this implementation scheme, the main dust exhaust pipe 1 is suspended from the top of the mineral processing plant, with one end of the main dust exhaust pipe 1 located outside the plant or connected to an air handling unit. Suction pipes 3 are installed below the conveying branch pipe 101, allowing multiple suction pipes 3 to be suspended near the mineral processing workstations. Alternatively, by adding bends or flexible connections, they are aligned with the processing area. Starting the dust extraction motor 305 drives the blades 306 to rotate. The rotation of the blades 306 draws air from the dust extraction hood 302 into the suction pipes 3, which then discharge the air to the outside of the plant or the air handling unit, thus achieving the purpose of dust removal from the plant. Multiple suction pipes 3 are initially evenly distributed. Figure 1 The middle section is only one section of this device. Multiple suction pipes 3 can be used to suck up dust inside the factory, resulting in better dust suction and discharge. At the same time, the filter frame 5 is set inside the suction pipe 3. The dust filter 501 can perform preliminary filtration of dust, preventing large dust particles from being sucked into the device and accumulating inside the pipes, which is difficult to clean. This also reduces the pressure of subsequent dust treatment.

[0025] Example 2 The lower end of the conveying pipe 101 is fixedly connected to a first flange 102, and the upper end of the suction pipe 3 is fixedly connected to a second flange 301. The second flange 301 and the first flange 102 are fixedly connected by bolts. Several retaining rings 103 are fixedly connected to the outer wall of the main dust discharge pipe 1. Two fixing collars 2 are symmetrically engaged in the retaining rings 103. Through holes are opened on the upper fixing collars 2 near the two side edges. Fixing bolts 201 are installed in the through holes. A hanger rod 202 is fixedly connected to the upper fixing collar 2. A fixing foot 203 is fixedly connected to the hanger rod 202.

[0026] In this embodiment, the second flange 301 and the first flange 102 cooperate with each other, and the suction pipe 3 can be fixed to the bottom of the conveying branch pipe 101 with bolts. The modular design facilitates the initial installation and transportation. The two fixing collars 2 can form a clamp. The two fixing collars 2 can be fixed together by using the fixing bolts 201 through the through hole and tied to the outer wall of the main dust discharge pipe 1. The fixing feet 203 and the pins can be used to fix the hanger 202 to the top of the factory building, thereby suspending the main dust discharge pipe 1 on the top of the factory building. First, the area occupied by the device is minimized. Second, the suspended design can better suck up the suspended dust.

[0027] Example 3 The lower edge of the dust hood 302 has a threaded groove 303 on its outer wall. A threaded collar 307 is threaded onto the threaded groove 303. A raised edge is fixed to the lower part of the threaded collar 307. The raised edge cooperates with the bracket 4. The lower edge of the dust hood 302 has a slot. The bracket 4 is slidably installed in the slot. A support screw 402 is fixed to the bottom of the collection cup 401. A connector 502 is fixed to the lower part of the filter frame 5. A connecting threaded hole 503 is opened at the lower end of the connector 502. The connecting threaded hole 503 is threadedly engaged with the support screw 402. A row of through grooves is opened in the bracket 4 near the outer edge. A sealing ring is fixed to the outer wall of the filter frame 5. The diameter of the filter frame 5 is the same as the inner diameter of the suction pipe 3.

[0028] In this embodiment, the bracket 4 is slidably installed inside the slot on the inner wall of the dust collection hood 302. Then, the threaded collar 307 is rotated and installed from the lower end of the dust collection hood 302. The protruding edge under the threaded collar 307 will support the lower part of the bracket 4, thereby squeezing and fixing the bracket 4 inside the slot. The bracket 4 is fixed inside the dust collection hood 302. The filter frame 5 is supported and installed inside the suction pipe 3 by the support screw 402. The dust filter 501 can intercept larger dust particles. The dust will adhere to the surface of the dust filter 501 due to suction. When the machine stops, the large dust particles lose suction and will fall directly into the collection cup 401 due to gravity and be collected. This prevents the particles adhering to the surface of the dust filter 501 from floating and falling back into the factory due to the machine stopping. The support screw 402 is threadedly engaged with the connecting threaded hole 503. The filter frame 5 can be directly unscrewed later, which is convenient for the periodic replacement or cleaning of the filter frame 5 and the dust filter 501.

[0029] The working principle and usage process of this invention: The fixing foot 203, together with the pin, can fix the hanging rod 202 to the top of the factory building, thereby suspending the main dust exhaust pipe 1 from the top of the factory building, so that one end of the main dust exhaust pipe 1 is located outside the factory building or connected to the air handling unit. Starting the dust extraction motor 305 can drive the blades 306 to rotate. The rotation of the blades 306 can draw air from the dust extraction hood 302 into the suction pipe 3. During the process of the air entering the suction pipe 3, it will first pass through the dust filter 501 to filter large dust particles, so as to prevent large dust particles from being drawn into the device and depositing inside the pipe, which is difficult to clean. The remaining dust will be discharged from the outside of the factory building or the air handling unit through the suction pipe 3, so as to achieve the purpose of dust discharge from the inside of the factory building.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
