Description

Technical Field

[0001] This invention relates to the field of respirable dust separation technology, specifically to a respirable dust separation device based on electrocondensation. Background Technology

[0002] Respirable dust refers to dust with an aerodynamic equivalent diameter of less than 7.1 μm that can enter the lungs through respiration. This type of dust is harmful to human health and is one of the sources of pneumoconiosis. Existing mines generate large amounts of respirable dust in the air due to mining operations. Prolonged inhalation of this dust in dusty work environments can lead to pneumoconiosis in workers, posing a threat to their personal safety.

[0003] Currently, there are three main technologies used for respirable dust separation at home and abroad: ceramic separation, impact separation, and cyclone separation. However, all three separation methods require manual cleaning of the separated dust to ensure the long-term use of the separation device. This makes it difficult to maintain continuous detection of respirable dust, requiring frequent cleaning and resulting in poor processing continuity. As the usage time increases, the dust separation effect deteriorates, the separation efficiency is low, and it affects the working environment inside the mine. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a respirable dust separation device based on electrocoagulation, comprising: a horizontal pipe and a detection pipe, wherein the detection pipe is installed at the right end of the horizontal pipe and the right end of the detection pipe gradually slopes upward relative to the left end; an electrocoagulation flow guiding and separation structure is installed inside the horizontal pipe; a detection separation circulation structure is installed on the detection pipe; a dust leakage port is opened on the lower wall at the connection between the horizontal pipe and the detection pipe; and a bag filter structure is installed below the dust leakage port.

[0005] The electrocondensation flow separation structure includes: an air inlet hopper, a partition baffle, a positive electrode post, a negative electrode post, a pair of cleaning brushes, a pair of cleaning drive components, and several flow-around columns;

[0006] An air intake hopper is installed at the left end of the horizontal pipe. A partition baffle is installed horizontally at the middle of the left end of the inner wall of the horizontal pipe. A positive electrode post is installed above the partition baffle, and a negative electrode post is installed below the partition baffle. A pair of drive cleaning components are installed on the upper and lower walls of the inner wall of the horizontal pipe. A pair of cleaning brushes are respectively fitted on the positive and negative electrode posts. Several flow-around columns are installed on the right side of the partition baffle.

[0007] Preferably, each pair of drive cleaning components includes: a drive box, a mounting cavity, a motor box, a drive motor, a lead screw, and a moving block;

[0008] The drive box is installed on the inner wall of the horizontal pipe, and the mounting cavity is opened inside the drive box. The motor box is installed behind the drive box, and the drive motor is installed inside the motor box. The two ends of the spiral screw are embedded in the mounting cavity. One end of the spiral screw is connected to the output end of the drive motor. The moving block is installed on the spiral screw through a threaded fit and is connected to the cleaning brush.

[0009] Preferably, the lead screw is mounted on the inner wall of the mounting cavity via a bearing.

[0010] Preferably, the detection separation circulation structure includes: a detection controller, a dust detection probe, an exhaust switch valve, a mounting base, a circulating air pump, an air intake pipe, and a circulating air delivery pipe;

[0011] The detection controller is installed on the left end of the upper outer wall of the detection pipe. The dust detection probe is embedded in the inner wall of the detection pipe and electrically connected to the detection controller. The exhaust switch valve is embedded at the right end of the detection pipe. The mounting base is installed on the right side of the detection controller. The circulating air pump is installed above the mounting base. One end of the suction pipe is installed on the air inlet of the circulating air pump and the other end extends into the inside of the detection pipe.

[0013] Preferably, a support frame is installed on the circulating gas pipeline.

[0014] Preferably, the bag filter structure includes: a dust collection box, a dust collection chamber, a fixed outer frame, a dust collection bag, and two pairs of fixed pressure plates;

[0015] The dust collection box is installed below the dust leakage port on the lower wall where the horizontal pipe and the detection pipe connect. The dust collection chamber is located inside the dust collection box. The fixed outer frame is installed on the upper part of the inner wall of the dust collection chamber. The dust collection bag is installed on the fixed outer frame by two pairs of fixed pressure plates.

[0016] Preferably, the fixing plate is installed on the fixing outer frame by fixing bolts.

[0017] Preferably, a protective grille is installed on the lower wall of the dust collection box.

[0018] The beneficial effects of this invention are as follows: This solution uses electrocoagulation to separate respirable dust, which is a dust separation technology based on the electric field effect. It combines electric field force and particle coagulation to achieve effective separation of respirable dust. Under the action of electric field force, dust particles with opposite charges will generate differences in velocity or direction, thereby achieving effective coagulation and forming larger particle clusters. These large particle clusters are then effectively collected by electrostatic precipitators or other collection devices, thus avoiding the dust accumulation problem in the prior art. This ensures the long-term continuous use of the respirable dust separation device and solves the problems of existing respirable dust separation equipment that accumulates dust with increasing working time, requires frequent cleaning, has poor continuity, requires maintenance of its separation structure by personnel, has low efficiency, and is relatively cumbersome to operate.

Detailed Implementation

[0025] 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.

[0026] like Figure 1-5As shown, a respirable dust separation device based on electrocoagulation mainly consists of a horizontal pipe 1, a detection pipe 2, an electrocoagulation flow guiding and separation structure, a detection and separation circulation structure, a dust leakage port 3, and a bag filter structure. The horizontal pipe 1 and the detection pipe 2 are connected to form the main body of the device, and the right end of the detection pipe 2 gradually slopes upward relative to the left end.

[0027] The electrocondensation flow separation structure mainly consists of an air inlet hopper 4, a partition baffle 5, a positive electrode column 6, a negative electrode column 7, a pair of cleaning brushes 8, a pair of cleaning drive components, and several flow-around columns 9.

[0028] The air intake hopper 4 is installed at the left end of the horizontal pipe 1. The partition baffle 5 is horizontally installed at the middle of the left end of the inner wall of the horizontal pipe 1. The positive electrode post 6 is installed above the partition baffle 5. The negative electrode post 7 is installed below the partition baffle 5. A pair of drive cleaning components are installed on the upper and lower inner walls of the horizontal pipe 1. A pair of cleaning brushes 8 are respectively fitted on the positive electrode post 6 and the negative electrode post 7. Several flow-around columns 9 are installed on the right side of the partition baffle 5.

[0029] When using the electrocoagulation and separation structure, the dust-laden airflow is drawn into the horizontal pipe 1 through the air inlet hopper 4. The dust-laden airflow is split into two airflows, upper and lower, by the partition baffle 5. The dust in the airflow carries corresponding charges under the electric field of the positive electrode column 6 and the negative electrode column 7. The charged dust causes the airflow to change direction under the action of the flow column 9, resulting in differences in speed and direction of the dust, thereby achieving effective coagulation and forming larger particle clusters. This separates respirable dust from the air and allows it to enter the bag filter structure. During operation, some dust adheres to the outer wall surface of the positive electrode column 6 and the negative electrode column 7, affecting the subsequent electrocoagulation effect. The cleaning drive component drives the cleaning brush 8 to move and clean the surface.

[0030] The drive cleaning assembly mainly consists of a drive box 10, a mounting cavity 11, a motor box 12, a drive motor 13, a lead screw 14, and a moving block 15.

[0031] The drive housing 10 is installed on the inner wall of the horizontal pipe 1. The mounting cavity 11 is located inside the drive housing 10. The motor housing 12 is installed behind the drive housing 10. The drive motor 13 is installed inside the motor housing 12. Both ends of the lead screw 14 are embedded in the mounting cavity 11. One end of the lead screw 14 is connected to the output end of the drive motor 13. A moving block 15 is threaded onto the lead screw 14 and is connected to the cleaning brush 8. Furthermore, the lead screw 14 is embedded in the inner wall of the mounting cavity 11 via a bearing 16.

[0032] When the drive cleaning component is working, the drive motor 13 installed in the motor housing 12 starts to rotate. The drive motor 13 drives the spiral screw 14 connected to its output end and installed in the mounting cavity 11 inside the drive housing 10 through the rotary bearing 16 to rotate. The rotation of the spiral screw 14 drives the moving block 15 installed with its thread to move, thereby driving the cleaning brush 8 to reciprocate on the surface of the positive electrode post 6 and the negative electrode post 7 to clean the surface.

[0033] The detection and separation circulation structure mainly consists of a detection controller 17, a dust detection probe 18, an exhaust switch valve 19, a mounting base 20, a circulating air pump 21, an air intake pipe 22, and a circulating air delivery pipe 23.

[0034] The detection controller 17 is installed on the left end of the upper outer wall of the detection pipe 2. The dust detection probe 18 is embedded in the inner wall of the detection pipe 2 and electrically connected to the detection controller 17. The exhaust switch valve 19 is embedded at the right end of the detection pipe 2. The mounting base 20 is installed to the right of the detection controller 17. The circulating air pump 21 is installed above the mounting base 20. One end of the suction pipe 22 is installed on the air inlet of the circulating air pump 21, and the other end extends into the detection pipe 2. One end of the circulating air supply pipe 23 is installed on the circulating air pump 21, and the other end is connected to the air inlet hopper 4. An air inlet hopper 24 is installed on the suction pipe 22. A support frame 25 is installed on the circulating air supply pipe 23.

[0035] When using the detection separation circulation structure, the separated airflow is transported into the detection pipe 2. As the airflow flows, the dust detection probe 18 detects the dust content in the air. When the dust content is higher than the equipment value, the exhaust switch valve 19 closes, and the circulating air pump 21 installed on the mounting base 20 starts to draw out the air through the suction pipe 22 and circulate it back to the air intake hopper 4 through the circulating air delivery pipe 23 for electro-condensation separation treatment again. When the detected data is lower than the set value, the exhaust switch valve 19 opens and discharges the air into the open space.

[0036] The bag filter structure mainly consists of a dust collection box 26, a dust collection chamber 27, a fixed outer frame 28, a dust collection bag 29, and two pairs of fixed pressure plates 30.

[0037] The dust collection box 26 is installed below the dust leakage port 3 on the lower wall surface at the connection between the horizontal pipe 1 and the detection pipe 2. The dust collection chamber 27 is located inside the dust collection box 26. The fixed outer frame 28 is installed on the upper part of the inner wall of the dust collection chamber 27. The dust collection bag 29 is installed on the fixed outer frame 28 by two pairs of fixed pressure plates 30. Furthermore, the fixed pressure plates 30 are installed on the fixed outer frame 28 by fixing bolts 31. A protective grille 32 is installed on the lower wall surface of the dust collection box 26.

[0038] When using a bag filter structure, respirable dust agglomerates into larger particle clusters under the action of electric charge and the surrounding column 9. Due to gravity, the dust particles enter the dust collection chamber 27 inside the dust collection box 26 when passing through the dust leakage port 3. The dust collection bag 29 installed in the dust collection chamber 27 through the fixed outer frame 28 and the fixed pressure plate 30 filters and collects the dust particles, thereby ensuring the separation effect of respirable dust.
