Description

Technical Field

[0001] The invention relates to the technical field of electrostatic dust removal equipment, in particular to an adsorption-type high-efficiency dust removal device. Background Art

[0002] Electrostatic precipitators are highly efficient air and gas purification devices widely used in industrial and commercial applications. They use high-voltage electric fields to charge dust in the airflow, and then use the electric field force to capture the charged dust on the collecting electrode to achieve gas-solid separation. Although electrostatic precipitators perform well in handling dust-laden gases with large air volumes, high temperatures, and high humidity, they have some limitations, especially in terms of maintenance and cleaning after long-term operation. As the operating time increases, a large amount of dust will gradually accumulate on the collecting electrode, affecting the efficiency of corona discharge, reducing the dust removal effect, and may cause electrical failures of the equipment.

[0003] Traditional cleaning methods, such as mechanical vibration and gas backflushing, can solve the cleaning problem of dust collecting plates to a certain extent, but they each have their own shortcomings. Although mechanical vibration can effectively remove dry powder dust, it is not effective in removing dust with strong adhesion. In addition, since the dust adsorption amount of each adsorption plate is different, the required vibration frequency is also different. Most of the existing equipment vibrates all adsorption plates synchronously. Frequent vibration will cause accelerated equipment wear and increase maintenance costs. Gas backflushing can remove tiny particles and sticky dust, but when used alone, it may not be able to fully loosen tightly attached dust clumps due to lack of physical impact, affecting the dust removal efficiency. Therefore, an adsorption-type high-efficiency dust removal device is needed to solve the above problems. Summary of the invention

[0007] As a preferred adsorption-type high-efficiency dust removal device of the present invention, the number of installed levers on the upper tension roller decreases from the air inlet end to the air outlet end, and the levers are arranged in an equidistant circular array on the upper tension roller.

[0009] As a preferred embodiment of the adsorption-type high-efficiency dust removal device of the present invention, a crescent-shaped protrusion is arranged at the bottom of the knocking cam, and the lever is connected to the crescent-shaped protrusion in sliding contact.

[0010] As a preferred adsorption-type high-efficiency dust removal device of the present invention, the upper roller is provided with a plurality of mounting holes in a circumferential array, the lever is slidably installed in the mounting holes, and both ends of the lever are provided with threaded fixing nuts.

[0011] As a preferred adsorption-type high-efficiency dust removal device of the present invention, the front end surface of the electrostatic precipitator body is provided with a sliding hole, the connecting rod and the compression spring are installed in the sliding hole, and the connecting rod is elastically slidably connected to the electrostatic precipitator body through the compression spring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention improves the dust removal efficiency and the adaptability of the equipment by changing the number of levers and adjusting the vibration frequency according to the dust load of the dust collecting plates in different areas. The area near the air inlet has more dust, so a higher vibration frequency is used; while the area near the air outlet has less dust, so the vibration frequency is reduced to avoid excessive wear and secondary dust. Each knocking cam works independently and can automatically adjust the vibration frequency according to the dust collection conditions in each area, ensuring that the dust removal process is continuous and effective, and avoiding the concentrated dust phenomenon caused by simultaneous knocking.

[0016] 2. The present invention can effectively remove most of the dry powder dust on the dust collecting plate by vibration dust removal, while the purge dust removal can further remove the residual tiny particles and dust with strong adhesion. The combination of the two greatly improves the thoroughness and efficiency of dust removal. The physical impact during the vibration process loosens the dust, and the subsequent purge uses the powerful power of compressed air to blow the dust into the dust outlet. This dynamic synergy ensures the cleanliness of the dust collecting plate surface and maintains the high efficiency of the electrostatic precipitator.

[0017] 3. The present invention realizes the vibration of the dust collecting plate through the design of cam and lever structure. It has a simple structure and low production cost. The overall structure is located outside the equipment and is easy to maintain. The detachable installation method of the lever allows the user to adjust the number and position according to actual needs, thereby enhancing the flexibility and maintenance convenience of the equipment.

DETAILED DESCRIPTION

[0020] See also Figure 1-Figure 7 , an adsorption-type high-efficiency dust removal device, comprising an electrostatic precipitator body 1, a partition-type knocking mechanism 2 is arranged on the side of the electrostatic precipitator body 1, and a purge mechanism 3 is arranged on the top of the electrostatic precipitator body 1; The electrostatic precipitator body 1 is provided with a corona electrode 104 and a dust collecting electrode plate 105, the left and right ends of the electrostatic precipitator body 1 are respectively provided with an air inlet 101 and an air outlet 102, and the bottom of the electrostatic precipitator body 1 is provided with a dust discharge port 103; The partitioned knocking mechanism 2 includes a motor 201, a reducer 202, an upper roller 203, a knocking cam 204, a connecting rod 205 and a compression spring 209. The dust collecting plate 105 is fixedly mounted on the connecting rod 205. The partitioned knocking mechanism 2 is mounted on the front end surface of the electrostatic precipitator body 1. The purge mechanism 3 includes an air pressure tank 301 , a conduit 302 and a nozzle 303 . A sealing plug 304 cooperating with the nozzle 303 is provided on the connecting rod 205 . The purge mechanism 3 is fixedly mounted on the top of the electrostatic precipitator body 1 .

[0021] Furthermore, the front end face of the electrostatic precipitator body 1 is provided with a first rotating shaft 207 and a second rotating shaft 208, the motor 201 is rotationally connected to the first rotating shaft 207 through a reducer 202, the upper tensioning roller 203 is fixedly mounted on the first rotating shaft 207, and the upper tensioning roller 203 is provided with a lever 206 that cooperates with the rotating knocking cam 204.

[0022] The motor 201 drives the first rotating shaft 207 to rotate continuously and slowly through the reducer 202, so that the lever 206 moves the crescent protrusion 2041 at the bottom of the knocking cam 204, driving the knocking cam 204 to rotate. When the knocking cam 204 rotates to a certain angle, the lever 206 slips off the surface of the crescent protrusion 2041, causing the knocking cam 204 to rebound under the resetting action of the torsion spring 2042, thereby quickly hitting the connecting rod 205, causing the connecting rod 205 to drive the dust collecting plate 105 to shake, shaking off the dust on its surface.

[0023] Furthermore, the number of the levers 206 installed on the upper tension roller 203 decreases from the air inlet 101 end to the air outlet 102 end, and the levers 206 are arranged in an equidistant circular array on the upper tension roller 203 .

[0024] The frequency of beating the dust collecting plate 105 is changed by changing the number of levers 206. Since the dust collecting plate 105 near the air inlet 101 has the most dust, the beating frequency needs to be increased to maintain a high adsorption rate. There is less dust on the surface of the dust collecting plate 105 near the air outlet 102. Frequent beating will reduce the service life of the equipment and generate dust in the electrostatic precipitator, affecting the dust removal effect.

[0025] Furthermore, the knocking cam 204 is installed on the second rotating shaft 208 through a bearing, and a torsion spring 2042 is provided between the knocking cam 204 and the second rotating shaft 208 , and the knocking cam 204 and the second rotating shaft 208 are rotationally connected through the torsion spring 2042 .

[0026] Each knocking cam 204 rotates independently, so that the knocking cam 204 can vibrate the connecting rod 205 according to its own frequency. The connecting rods 205 can adjust themselves according to the dust collection rate of the dust collecting plate 105, so that part of the dust collecting plates 105 can be knocked while the other part remains in operation, avoiding the dust collecting plates 105 shaking off dust at the same time due to simultaneous knocking, causing a large amount of dust to be generated in the equipment, and the equipment temporarily losing its purification ability.

[0027] Furthermore, a crescent-shaped protrusion 2041 is provided at the bottom of the striking cam 204 , and the lever 206 is connected to the crescent-shaped protrusion 2041 in sliding contact.

[0028] The lever 206 moves the crescent-shaped protrusion 2041 at the bottom of the knock cam 204, driving the knock cam 204 to rotate, causing the torsion spring 2042 to elastically deform. When the knock cam 204 rotates to a certain angle, the lever 206 slips off the surface of the crescent-shaped protrusion 2041, causing the knock cam 204 to rebound under the resetting action of the torsion spring 2042.

[0029] Furthermore, a plurality of mounting holes 2031 in a circumferential array are provided on the upper tensioning roller 203 , and the lever 206 is slidably installed in the mounting holes 2031 . Both ends of the lever 206 are provided with threaded fixing nuts.

[0030] The detachable installation method allows the user to freely install the number and position of the levers 206 according to their own needs, and freely assemble according to the dust removal rate and dust removal period, thereby improving the applicability of the equipment.

[0031] Furthermore, a sliding hole 106 is provided on the front end surface of the electrostatic precipitator body 1 , and a connecting rod 205 and a compression spring 209 are installed in the sliding hole 106 . The connecting rod 205 is elastically slidably connected to the electrostatic precipitator body 1 via the compression spring 209 .

[0032] When the connecting rod 205 is struck, the compression spring 209 can be squeezed to swing back and forth, thereby driving the dust collecting plate 105 to shake quickly to shake off the dust on its surface, and at the same time driving the sealing plug 304 to shake, so that it intermittently cooperates with the nozzle 303, so that the nozzle 303 can intermittently spray air to purge the dust collecting plate 105.

[0033] Furthermore, the nozzle 303 is connected with the conduit 302, and the sealing plug 304 is fixedly installed on the connecting rod 205. The sealing plug 304 is located at the lower end of the nozzle 303 and fits with the nozzle 303, and the sealing plug 304 is connected with the inner end surface of the electrostatic precipitator body in sliding contact.

[0034] The sealing plug 304 shields the nozzle 303 to prevent the nozzle 303 from spraying high-pressure air during use. When the connecting rod 205 vibrates, the sealing plug 304 and the nozzle 303 are intermittently misaligned, so that the nozzle 303 intermittently sprays high-pressure air to purge the surface of the dust collecting plate 105.

[0035] Furthermore, the nozzle 303 is a Y-shaped three-way pipe, and the angle between the bottom air outlet of the nozzle 303 and the horizontal plane is forty-five degrees.

[0036] The gas ejected from the nozzle 303 is blown obliquely toward the dust collecting plate 105 , which is more conducive to blowing off the dust attached to its surface and improving the adsorption effect of the dust collecting plate 105 .

[0037] Furthermore, a wear-resistant block 2051 cooperating with the knock cam 204 is provided at the front end of the connecting rod 205 .

[0038] The wear-resistant block 2051 increases the impact resistance of the front end of the connecting rod 205, thereby preventing the connecting rod 205 from being deformed or damaged by frequent knocks, thereby improving the overall service life of the equipment.

[0039] When the device is in use, before starting, ensure that all components are installed correctly and without damage, check whether all connection parts are tightened, check whether the air supply pressure of the air compressor tank 301 meets the requirements, ensure that the power supply is stable, and all electrical connections are safe and reliable. According to the dust distribution of the dust collecting plate 105, by adjusting the number and position of the lever 206 on the upper tension roller 203, the vibration frequency of different areas is preset to adapt to the change of dust load from the air inlet 101 to the air outlet 102. In this embodiment, three groups of upper tension rollers 203 are taken as an example. Three, two and one levers 206 are respectively provided on the three groups of upper tension rollers 203. During the operation of the equipment, the motor 201 drives the first rotating shaft 207 through the reducer 202, so that the upper tension roller 203 starts to rotate slowly, and the lever 206 on the upper tension roller 203 rotates with it, and sequentially moves the corresponding crescent protrusion 2 at the bottom of the knock cam 204. 041, triggering the knocking cam 204 to rotate and rebound under the action of the torsion spring 2042, quickly hitting the connecting rod 205, so that the connecting rod 205 drives the dust collecting plate 105 to vibrate, thereby shaking off the dust on the surface, and the upper roller 203 near the air inlet 101 end knocks three times per rotation, the upper roller 203 in the middle part knocks on both sides per rotation, and the upper roller 203 near the air outlet 102 end knocks once per group of rotation. During the vibration process, the vibration of the connecting rod 205 drives the sealing plug 304 installed thereon to intermittently cooperate with the nozzle 303. When the sealing plug 304 and the nozzle 303 are misaligned, the nozzle 303 intermittently sprays the high-pressure air stored in the air compression tank 301 to sweep the surface of the dust collecting plate 105, further remove the residual tiny particles and dust with strong adhesion, and blow the dust to the dust outlet 103. After the equipment is running, turn off the power of the equipment in time.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
