Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a metal processing dust monitoring and automatic dust removal device. Background Technology

[0002] Metal processing refers to the industrial manufacturing process of changing the shape, improving the properties, or treating the surface of metal materials through physical or chemical methods. It encompasses a variety of processes such as casting, forging, stamping, cutting, welding, heat treatment, powder metallurgy, and additive manufacturing. It is widely used in fields such as machinery manufacturing, automobiles, aerospace, electronics, and building hardware. The pollutants such as dust, smoke, and oil mist generated during the process need to be treated through specialized monitoring and dust removal equipment to meet environmental protection requirements.

[0003] Metal processing dust monitoring and automatic dust removal equipment is a comprehensive industrial environmental protection device that integrates real-time monitoring and intelligent purification. Its core function is to continuously monitor metal dust generated during metal cutting, grinding, welding and other processing processes through dust concentration sensors, visual recognition systems or laser scattering detection technologies. When the dust concentration exceeds the preset safety threshold, the dust removal mechanism is automatically triggered, realizing full-process automated control from the dust generation source to the emission end, thereby effectively reducing the dust concentration in the workplace, preventing the risk of dust explosion, ensuring occupational health and safety and meeting environmental emission standards.

[0004] However, when using baghouse dust collectors, the high-temperature dust generated during metal processing may become brittle or even melt when it comes into prolonged contact with the dust bags inside the dust collector, thus affecting its service life. Furthermore, existing baghouse dust collectors use nozzles to spray gas into the filter bags, using high-pressure pulsed airflow to cause the filter bags to expand instantaneously and peel off surface dust. This cleaning structure results in excessively high blowing pressure near the nozzle at the bag opening, while the pressure is higher at the bottom of the bag further away from the nozzle. This may lead to insufficient blowing intensity to completely remove the dust layer, resulting in over-cleaning at the top and under-cleaning at the bottom. Therefore, this design does not meet current requirements. To address this, we propose a metal processing dust monitoring and automatic dust removal device. Summary of the Invention

[0005] The purpose of this invention is to provide a metal processing dust monitoring and automatic dust removal device to solve the problems mentioned in the background art. In the case of baghouse dust collectors, the high-temperature dust generated during metal processing may become brittle or even melt when in prolonged contact with the dust collection bags inside the baghouse, thus affecting their service life. Furthermore, existing baghouse dust collectors use nozzles to spray gas into the filter bags, utilizing high-pressure pulsed airflow to instantly expand the filter bags and peel off surface dust. However, this cleaning structure results in excessively high blowing pressure near the nozzle at the bag opening, while the pressure is higher at the bottom of the bag further from the nozzle. This may lead to insufficient blowing intensity to completely remove the dust layer, resulting in problems such as over-cleaning at the top and insufficient cleaning at the bottom.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal processing dust monitoring and automatic dust removal device, comprising a bag filter body, wherein a high-temperature dust cooling mechanism is fixed to the front end face of the bag filter body, the high-temperature dust cooling mechanism comprising a spring-shaped dust gas flow channel, a spring-shaped outer cooling pipe fixed to the inner wall of the spring-shaped dust gas flow channel, and a spring-shaped inner cooling pipe provided on the inner side of the spring-shaped outer cooling pipe, wherein the spring-shaped inner cooling pipe, the spring-shaped dust gas flow channel and the spring-shaped outer cooling pipe are all spring-shaped, and both the spring-shaped inner cooling pipe and the spring-shaped outer cooling pipe contain circulating coolant inside;

A spring is provided inside the annular sleeve in a number corresponding to the number of anti-detachment sleeves, and the lower end face of the plurality of springs is respectively in contact with the upper end face of the plurality of anti-detachment sleeves.

[0011] Preferably, the uppermost annular sleeve is fixedly connected to a top fixing ring that is sleeved on the outer surface of the inner support bracket of the dust collector bag, and the top fixing ring is fixed to the inner support bracket of the dust collector bag by multiple bolts.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The high-temperature dust cooling mechanism of this invention has a spring-shaped dust gas flow channel inside. The inner side of the spring-shaped dust gas flow channel is provided with a spring-shaped inner cooling pipe, and the inner wall is fixed with a spring-shaped outer cooling pipe. Both the spring-shaped dust gas flow channel and the spring-shaped outer cooling pipe contain circulating coolant. The spring-shaped dust gas flow channel in the above technical solution adopts a spiral structure to extend the flow path and residence time of the high-temperature dust gas flow, so that the gas flow forms a sufficient indirect heat exchange with the spring-shaped inner cooling pipe and the spring-shaped outer cooling pipe. The coolant circulating inside the spring-shaped inner cooling pipe and the spring-shaped outer cooling pipe continuously absorbs the heat of the high-temperature dust gas flow, and gradually reduces the gas flow temperature to a safe range, thereby avoiding damage to the subsequent dust collector bags due to high temperature and improving the service life of the dust collector bags.

[0022] 2. This invention enables rapid expansion and contraction of dust collector bags during dust removal operations through a pulsed, high-efficiency cleaning process. Multiple high-pressure gas nozzles on the gas distribution pipes deliver high-pressure gas to the inside of the dust collector bag, causing it to expand radially while simultaneously undergoing axial pulsed contraction-opening motions, creating a composite deformation pattern. This enhances the inertial peeling, shearing damage, and fatigue shedding of the dust layer. Furthermore, the multiple high-pressure gas nozzles are evenly arranged along the bag's length, working in conjunction with the pulsed expansion and contraction to solve the problems of pressure attenuation and uneven cleaning inherent in traditional single-nozzle cleaning. This achieves uniform cleaning intensity from the bag opening to the bottom. Through this comprehensive, multi-frequency, and deformable cleaning method, the dust removal rate on the surface of the dust collector bag is improved. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figures 1 to 6An embodiment of the present invention provides a metal processing dust monitoring and automatic dust removal device, comprising a bag filter body 1, a high-temperature dust cooling mechanism 2 fixed to the front end face of the bag filter body 1, the high-temperature dust cooling mechanism 2 including a spring-shaped dust gas flow channel 205, a spring-shaped outer cooling pipe 206 fixed to the inner wall of the spring-shaped dust gas flow channel 205, and a spring-shaped inner cooling pipe 204 provided on the inner side of the spring-shaped outer cooling pipe 206. The spring-shaped inner cooling pipe 204, the spring-shaped dust gas flow channel 205, and the spring-shaped outer cooling pipe 206 are all spring-shaped, and the inner cooling pipe 204 and the spring-shaped outer cooling pipe 206 both contain circulating coolant 207; a cooling tank 2. An air inlet 209 is located in the middle of the upper end face of the 01. Above the air inlet 209, a dust conveying pipe 22 is installed on the upper end face of the cooling tank 201 via a flange. Multiple dust extraction pipes 23 are fixedly installed on the lower end face of the dust conveying pipe 22, and a dust detection device 24 is installed on the lower end face of the dust extraction pipe 23. Before installing the device, the metal processing equipment is placed below the dust extraction pipe 23 for use. When the dust detection device 24 installed on the lower end face of the dust extraction pipe 23 detects that the dust concentration exceeds the preset safety threshold, the dust extraction pump in the dust extraction pipe 23 will automatically start, extract the gas containing dust in the air, and transport it to the interior of the air inlet 209 through the dust conveying pipe 22.

[0032] The high-temperature dust cooling mechanism 2 also includes a cooling water circulation pump 202. A connecting pipe 203 is fixedly installed on both sides of the outer surface of the cooling water circulation pump 202, and a spring-shaped inner cooling pipe 204 is fixedly installed between the two connecting pipes 203.

[0033] A ring of diversion pipes 208 is installed on the outer surface of the connecting pipe 203 at a position corresponding to the spring-shaped outer cooling pipe 206, and the interior of the diversion pipe 208 is connected to the interior of the spring-shaped outer cooling pipe 206; when the dust extraction pump is started, the cooling water circulation pump 202 will start automatically, and the cooling water circulation pump 202 can drive the coolant 207 inside the spring-shaped inner cooling pipe 204, which is connected to it through the two connecting pipes 203, to flow along the spring-shaped outer cooling pipe 206;

[0034] When the coolant 207 inside the spring-shaped inner cooling pipe 204 is driven to flow through the connecting pipe 203, a portion of the coolant 207 will enter the interior of the spring-shaped outer cooling pipe 206 through the diversion pipe 208 and flow along the spring-shaped outer cooling pipe 206.

[0035] When the high-temperature dust gas enters the interior of the inlet 209, it will enter the interior of the spring-shaped dust gas flow channel 205 located on the lower end face of the inlet 209 and flow along the spring-shaped dust gas flow channel 205.

[0036] The spring-shaped dust gas flow channel 205 in the above technical solution adopts a spiral structure to extend the flow path and residence time of the high-temperature dust gas, thereby ensuring that the high-temperature dust gas can form sufficient indirect heat exchange with the spring-shaped inner cooling pipe 204 and the spring-shaped outer cooling pipe 206. The coolant 207 circulating inside the spring-shaped inner cooling pipe 204 and the spring-shaped outer cooling pipe 206 can continuously absorb the heat of the high-temperature dust gas, gradually reducing the gas temperature to a safe range, thereby avoiding damage to the internal structure of the bag filter body 1 by high temperature.

[0037] A dust collector bag fixing plate 3 is fixed to the upper side inside the main body 1 of the bag filter. A high-pressure gas conveying pipe 5 for dust removal is provided above the dust collector bag fixing plate 3. The lower end of the high-pressure gas conveying pipe 5 for dust removal is connected to multiple pulsed high-efficiency dust removal bags, which are installed on the outer surface of the dust collector bag fixing plate 3. The pulsed high-efficiency dust removal bag includes a dust collector bag 4 and a pulsed shrinking mechanism. A dust collector bag bottom fixing frame 11 is fixed at the middle position of the lower end of the dust collector bag 4. A dust collector bag folding upper pushing plate 10 is fixed inside the dust collector bag bottom fixing frame 11. Multiple annular moving plates 12 are provided above the dust collector bag folding upper pushing plate 10. A ring of dust collector bag fixing brackets 18 is fixed to the outer surface of the dust collector bag folding upper pushing plate 10 and the annular moving plates 12. The top end of the dust collector bag fixing bracket 18 passes through the dust collector bag 4. Furthermore, a pressing and fixing sleeve 21 that fits between the dust collector bag 4 is fixed on both sides of the outer surface of the top end of the dust collector bag fixing bracket 18; an air outlet 210 is provided at the middle position of the lower end face of the cooling tank 201, and a connecting pipe 25 is provided below the air outlet 210 and installed on the lower end face of the cooling tank 201 through a flange, and the connecting pipe 25 communicates with the interior of the bag dust collector body 1; when the dust gas is stably reduced to a safe range, it will pass through the spring-shaped dust gas flow channel 205 and enter the interior of the bag dust collector body 1 through the air outlet 210 and the connecting pipe 25. When dust enters the interior of the bag dust collector body 1, the dust gas can be driven by the bag dust collector body 1 to flow in a spiral, so that it contacts the dust collector bag 4 and passes through the dust collector bag 4 for filtration, becoming dust-free gas.

[0038] An exhaust pipe is fixedly installed on the upper side of the rear end face of the bag filter body 1, and the height of the top end of the exhaust pipe is higher than that of the dust collector bag 4; finally, the dust-free gas will be discharged to the outside through the exhaust pipe.

[0039] The pulsating contraction mechanism can push the dust bag folding upper push plate 10 and the annular moving plate 12 upward to drive the dust bag 4, which is fixed to it by the dust bag fixing bracket 18, to contract or move downward. The dust bag folding upper push plate 10 and the annular moving plate 12 can then open the dust bag 4 again. The inner side of the dust bag 4 is provided with a gas diversion pipe 19 connected to the high-pressure gas conveying pipe 5 for dust removal. The high-pressure gas nozzle 20 is fixedly installed on the side of the gas diversion pipe 19 facing the inner wall of the dust bag 4. When it is necessary to clean the dust adhering to the outer surface of the dust bag 4, high-pressure gas is first conveyed into the gas diversion pipe 19 through the high-pressure gas conveying pipe 5 for dust removal. The high-pressure gas nozzles 20 installed on the outer surface of the gas diversion pipe 19 act on the dust bag 4, causing it to expand instantly, thereby removing the dust that is easier to remove in advance.

[0040] The outer surface of the dust collector bag fixing bracket 18 is provided with a strip-shaped through hole at a position corresponding to the gas diversion pipe 19. The gas diversion pipe 19 vertically passes through the strip-shaped through hole, and the distance between the gas diversion pipe 19 and the strip-shaped through hole is one centimeter. The strip-shaped through hole on the outer surface of the dust collector bag fixing bracket 18 can prevent the dust collector bag fixing bracket 18 from contacting the high-pressure gas nozzle 20 fixedly installed on the outer surface of the gas diversion pipe 19 when the dust collector bag fixing bracket 18 moves upward in the future, which would eventually cause the entire structure to jam.

[0041] The bottom end of the gas diversion pipe 19 extends vertically through the bottom fixing frame 11 of the dust collector bag, and the gas diversion pipe 19 is movably connected to the bottom fixing frame 11 of the dust collector bag; this structure ensures the stability of the gas diversion pipe 19 and prevents it from tilting.

[0042] The pulsating shrinkage mechanism includes an inner support bracket 6 for the dust collector bag. Slide rails 7 are fixedly installed on both sides inside the inner support bracket 6. An electric slider 8 is installed on both sides of the outer surface of each slide rail 7. An L-shaped connecting rod 9 is fixed to one side of the outer surface of each electric slider 8, and the surface of the L-shaped connecting rod 9 facing the upper push plate 10 for folding the dust collector bag is fixed to the upper push plate 10 for folding the dust collector bag. A connecting rod 17 is fixed to the upper end face of both the upper push plate 10 for folding the dust collector bag and the annular moving plate 12. An anti-detachment sleeve 16 is fixedly fitted onto the outer surface of the top end. A ring sleeve 14 is provided on the outer side of each of the multiple anti-detachment sleeves 16. Inside the ring sleeve 14 is a spring 15, the number of which corresponds to the number of anti-detachment sleeves 16. The lower end faces of the multiple springs 15 are respectively in contact with the upper end faces of the multiple anti-detachment sleeves 16. A top fixing ring 13, fitted onto the outer surface of the inner support bracket 6 of the dust collector bag, is fixedly connected to the upper end face of the uppermost ring sleeve 14. The top fixing ring 13 is also fixed to the inner support bracket 6 of the dust collector bag. The components are fixed together by multiple bolts. When the high-pressure gas nozzle 20 starts working, the electric slider 8 drives the dust bag folding upper push plate 10, which is connected to it by the L-shaped connecting rod 9, to move upward. As the dust bag folding upper push plate 10 rises, the dust bag bottom fixing frame 11, which is fixed to the outer surface of the dust bag folding upper push plate 10 and at the same time fixed to the lower end of the dust bag 4, will also move upward. As the dust bag bottom fixing frame 11 rises, the bottom end of the dust bag 4 will gradually fold. At this time, the bag body of the dust bag 4 will undergo axial compression deformation, and the filter bag wall will form regular wavy folds. At the same time, the multiple annular moving plates 12 above the dust bag folding upper push plate 10, under the elastic constraint of the connecting rod 17 and the spring 15, will move upward in sequence following the dust bag folding upper push plate 10. The distance between each annular moving plate 12 gradually decreases, thereby driving the bag body of the dust bag 4 fixed to it to shrink in a segmented and orderly manner.

[0043] The outer side of the top end of the L-shaped connecting rod 9 is provided with a sealing through hole located on the lower side of the inner support bracket 6 of the dust collector bag. The outer surface of the L-shaped connecting rod 9 is in contact with the inner wall of the sealing through hole, and the L-shaped connecting rod 9 and the sealing through hole are slidably connected. This structure can prevent dust that has passed through the dust collector bag 4 and been treated by dust removal from contacting the slide rail 7 and the electric slider 8 installed in the inner support bracket 6 of the dust collector bag during normal use of the equipment, thereby preventing it from affecting the equipment.

[0044] When the electric slider 8 can no longer move upward, the electric slider 8 drives the dust bag to fold and the upper push plate 10 to move downward to reset. The spring 15 releases its stored energy and pushes each annular moving plate 12 to unfold in the opposite direction. The folds of the dust bag 4 are quickly smoothed out and accompanied by radial elastic rebound, forming a complete contraction-opening pulsating cycle. During this process, the high-pressure gas nozzle 20 continuously blows airflow into the dust bag 4, so that the filter bag receives all-round dust cleaning in a dynamic deformation state. The dust layer falls off under the combined action of inertial peeling, shearing destruction and elastic vibration, thus achieving a deep cleaning effect that traditional static blowing cannot achieve.

[0045] The above technical solution can solve the problems of pressure attenuation and uneven dust removal along the process of traditional single-nozzle blowing, and achieve equal intensity dust removal from bag mouth to bag bottom. Through the all-round, multi-frequency and deformable dust removal method in the above technical solution, the dust removal rate on the surface of the dust collector bag 4 is improved.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
