Dust purification device for ore crushing processing

Abstract

The application discloses an ore crushing processing dust purification device, and belongs to the field of ore crushing processing. The ore crushing processing dust purification device comprises a crusher shell, and a plurality of first filter holes and second filter holes in the shape of a rectangular array are arranged on the feeding port side and the discharging port side of the crusher shell respectively. The ore crushing processing dust purification device forms a negative pressure area through a suction mechanism, so that the dust escaping from the crushing cavity and the belt machine discharging port is sucked into a purification mechanism. After the dust-containing air enters a conveying pipe, a spray head sprays water mist at the same time. Dust particles collide with water droplets to form slurry. The slurry moves to the end of the conveying pipe under the pushing of spiral blades. During the movement, residual slurry is pushed to the end of the conveying pipe by a spiral conveying rod. Purified air is discharged from the end of the conveying pipe. After treatment, waste water is recycled. The slurry is cleaned regularly.

Description

Technical Field

[0001] This application relates to the field of ore crushing and processing technology, specifically a dust purification device for ore crushing and processing. Background Technology

[0002] Ore crushing and processing is a core part of the mining and raw materials industry. It refers to crushing large pieces of ore or rock to a specific particle size using mechanical force, and may be accompanied by subsequent processing such as screening and grinding to meet industrial production needs.

[0003] Dry, brittle ores are more prone to generating dust during crushing. When the ore is squeezed and impacted in the crushing chamber, the internal air is forced out at high speed, carrying dust out from the feed and discharge ports. At the same time, the discharge port of the conveyor belt is also disturbed by the airflow caused by the falling material, which exacerbates the dust diffusion. However, most existing mine treatment methods rely on sprayers to suppress dust on the site. This can easily lead to ore dust covering the site, creating slippery surfaces and safety hazards. Furthermore, the ore dust is difficult to clean and collect, resulting in inconvenience and waste.

[0004] Therefore, this application provides a dust purification device for ore crushing and processing to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a dust purification device for ore crushing and processing, which aims to solve the problems mentioned in the background art of existing methods for cleaning dust during ore crushing and processing, which are prone to safety hazards and are inconvenient for cleaning and collection.

[0006] To achieve the above objectives, this application provides the following technical solution: a dust purification device for ore crushing and processing, comprising a crusher shell, wherein a plurality of first filter holes and second filter holes are respectively provided on the feed inlet side and the discharge outlet side of the crusher shell in a rectangular array, and an air extraction mechanism is provided on the side of the crusher shell to connect with the first filter holes and the second filter holes, and a purification mechanism is connected to the outlet end of the air extraction mechanism.

[0007] The purification mechanism includes a conveying pipe connected to the outlet end of the exhaust mechanism, a spiral conveying rod rotatably installed inside the conveying pipe, a motor fixedly installed at one end of the conveying pipe with its output shaft connected to the spiral conveying rod, several nozzles fixedly installed on the top of the conveying pipe in a linear array, a water pipe connected in series with the nozzles for connection to an external water supply system, a drain trough fixedly installed at the bottom of the conveying pipe and connected to the inside of the conveying pipe, and a wastewater connector fixedly connected to the drain trough for connection to an external wastewater treatment pipeline. Thus, during crushing operations, the exhaust mechanism creates a negative pressure zone between the first and second filter holes, drawing dust from the crushing chamber and the conveyor belt discharge port into the purification mechanism. After the dust-laden air enters the conveying pipe, water mist is sprayed from the nozzles. Dust particles collide with water droplets and condense into slurry. The slurry moves towards the end of the conveying pipe under the propulsion of the spiral blades. During this process, residual slurry is pushed to the end collection container by the spiral conveying rod. The purified air is discharged from the end of the conveying pipe, the wastewater is treated and recycled, and the slurry is cleaned periodically.

[0008] Preferably, the air extraction mechanism includes a three-way pipe fixedly connected to the side of the crusher housing and having two air inlets respectively connected to the first filter hole and the second filter hole, a rubber pipe connected to the air outlet of the three-way pipe, and a negative pressure fan fixedly installed in the air outlet of the three-way pipe.

[0009] Preferably, the rubber tube is a corrugated tube.

[0010] Preferably, several nozzles are also fixedly installed inside the rubber tube and connected in series through the water pipe.

[0011] Preferably, the edge of the spiral conveyor rod contacts the inner wall of the conveying pipe.

[0012] Preferably, a pair of supports are fixedly connected to both sides of the conveying pipe.

[0013] Preferably, the bottom of the conveying pipe is provided with a plurality of third filter holes arranged in a rectangular array for communicating with the interior of the draining tank.

[0014] This dust purification device for ore crushing and processing creates a negative pressure zone between the first and second filter holes through an air extraction mechanism. This draws in dust escaping from the crushing chamber and the conveyor belt discharge port. As the dust-laden air enters the conveying pipe, water mist is sprayed from the nozzles. Dust particles collide with water droplets and condense into slurry. The slurry moves towards the end of the conveying pipe under the propulsion of the spiral blades. During this process, residual slurry is pushed to the end collection container by the spiral conveyor rod. The purified air is discharged from the end of the conveying pipe, and the wastewater is treated and recycled. The slurry is cleaned periodically. Attached Figure Description

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This embodiment provides a dust purification device for ore crushing and processing, such as... Figs. 1-3 As shown, the dust purification device for ore crushing and processing includes a crusher housing 1. The feed inlet side and discharge outlet side of the crusher housing 1 are respectively provided with a plurality of first filter holes 11 and second filter holes 12 distributed in a rectangular array. An air extraction mechanism 2 is provided on the side of the crusher housing 1 to connect with the first filter holes 11 and second filter holes 12. The outlet end of the air extraction mechanism 2 is connected to a purification mechanism 3.

[0019] The purification mechanism 3 includes a conveying pipe 31 connected to the outlet end of the exhaust mechanism 2, a spiral conveying rod 32 rotatably installed inside the conveying pipe 31, a motor 33 fixedly installed at one end of the conveying pipe 31 with its output shaft connected to the spiral conveying rod 32, a number of nozzles 4 fixedly installed on the top of the conveying pipe 31 in a linear array, a water pipe 41 connected in series with the nozzles 4 for connecting to an external water supply system, a drain trough 34 fixedly installed at the bottom of the conveying pipe 31 and connected to the inside of the conveying pipe 31, and a wastewater connector 341 fixedly connected to the drain trough 34 for connecting to an external wastewater treatment pipeline. The bottom of the conveying pipe 31 is provided with a number of third filter holes 311 arranged in a rectangular array for communicating with the inside of the drain trough 34.

[0020] During operation, the extraction mechanism 2 is activated during crushing. A negative pressure zone is formed through the first filter hole 11 and the second filter hole 12, drawing dust from the crushing chamber and the conveyor belt discharge port into the purification mechanism 3. After the dust-laden air enters the conveying pipe 31, the screw conveyor 32 rotates and pushes it, while the nozzle 4 sprays water mist. Dust particles collide with water droplets and condense into slurry. The slurry moves towards the end of the conveying pipe 31 under the push of the screw blades. Water seeps out through the filter screen or gaps of the drain trough 34 and is discharged into the wastewater treatment pipeline through the wastewater connector 341. The residual slurry is pushed to the end collection container by the screw conveyor 32. The purified air is discharged from the end of the conveying pipe 31. The wastewater is recycled after treatment, and the slurry is cleaned periodically.

[0021] Specifically, the extraction mechanism 2 includes a three-way pipe 21 fixedly connected to the side of the crusher housing 1 and with its two air inlets connected to the first filter hole 11 and the second filter hole 12 respectively, a rubber pipe 22 connected to the air outlet of the three-way pipe 21, and a negative pressure fan 23 fixedly installed in the air outlet of the three-way pipe 21. The three-way pipe 21 is connected to the feed inlet filter hole 11, the discharge outlet filter hole 12 and the rubber pipe 22 of the crusher housing 1 through its three interfaces to form a negative pressure suction channel. At the same time, it covers the dust escape points of the feed inlet and discharge outlet, expands the collection range, and collects the dispersed dust into a single pipe for centralized treatment and avoids site pollution.

[0022] Specifically, rubber hose 22 is a corrugated hose; the corrugated hose has the characteristics to adapt to vibration, and at the same time, the corrugated hose achieves high flexibility through its pleated structure, allowing it to be bent and twisted to adapt to complex installation environments.

[0023] Furthermore, several nozzles 4 are also fixedly installed inside the rubber tube 22 and connected in series through the water pipe 41; the nozzles 4 are connected in series through the water pipe 41, and are pressurized by the external water supply system to form a fine water mist net inside the rubber tube 22, which is fully mixed with the dust-laden airflow.

[0024] Understandably, the edge of the spiral conveyor rod 32 contacts the inner wall of the conveying pipe 31; the edge of the spiral conveyor rod 32 is in close contact with the inner wall of the conveying pipe 31 through a micro-gap fit, and the rotation drives the airflow and slurry to move in a directional manner, while scraping the pipe wall to prevent dust deposition.

[0025] It should be noted that a pair of brackets 313 are fixedly connected to both sides of the conveying pipe 31; the brackets 313 are fixed to both sides of the conveying pipe 31 by welding, bear the weight of the pipe and maintain stability.

[0026] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
