Description

A dust suppression device for synthetic mica processing Technical Field

[0001] This invention relates to the field of synthetic mica processing technology, and in particular to a dust suppression device for synthetic mica processing. Background Technology

[0002] Synthetic mica is a mica material manufactured artificially. It has a layered structure similar to natural mica, as well as properties such as high temperature resistance, insulation, and corrosion resistance. It is widely used in electronics, chemical industry, aerospace and other fields. During the processing of synthetic mica, dust is easily generated in the crushing, grading and peeling processes. This not only pollutes the environment and endangers the health of workers, but may also cause explosion risks (especially for ultrafine mica powder). Therefore, it is necessary to equip it with a high-efficiency dust removal device.

[0003] During the processing, dust is usually treated by spraying. The outlet of the crusher is connected to the dust removal device through a duct. The dust-laden gas is introduced into the dust removal device for spraying treatment. The atomized spray liquid flows downward and the dust-laden gas flows upward. The two come into contact in opposite directions to remove dust. However, due to the uneven contact between the atomized spray liquid and the dust-laden gas, the dust removal effect is poor. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven contact between atomized spray liquid and dust-laden gas, which leads to poor dust removal efficiency. Therefore, this invention proposes a dust removal device for synthetic mica processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, a base is fixedly connected to the bottom end of the housing.

[0008] Preferably, the spraying mechanism includes a first support frame, which is fixedly connected to the housing. A liquid pump is fixedly connected to the upper end of the first support frame. The outlet end of the liquid pump is connected to a first connecting pipe. One end of the first connecting pipe is connected to a filter element. The upper end of the filter element is connected to a second connecting pipe. One end of the second connecting pipe extends into the housing and is connected to a circular annular pipe. The bottom end of the circular annular pipe is connected to a plurality of atomizing nozzles at equal intervals along the axial direction. The atomizing nozzles are located above the dispersing plate.

[0009] Preferably, the filter element includes an open bucket, the bottom of which is connected to a first connecting pipe, a filter screen is fixedly connected inside the open bucket, a sealing cap is sealed to the opening of the open bucket, and the upper end of the sealing cap is connected to a second connecting pipe.

[0010] Preferably, the bottom end of the perforated plate is connected to a gap discharge mechanism, the gap discharge mechanism including a first spring, one end of the first spring being connected to the bottom end of the perforated plate, the other end of the first spring being fixedly connected to a first movable plate, the first movable plate cooperating with the housing, the first movable plate having a plurality of through holes evenly spaced along the axis, and the bottom end of the perforated plate having a plurality of sealing rods evenly spaced along the axis, one end of each sealing rod being sealed and inserted into a corresponding through hole.

[0011] Preferably, the first spring is provided in a plurality of springs and is distributed at equal intervals along the axis of the perforated plate.

[0012] Preferably, a dehumidification mechanism is connected to the upper end of the housing. The dehumidification mechanism includes a geared motor, which is fixedly connected to the upper end of the housing. The output end of the geared motor extends into the housing and is fixedly connected to a filter screen. A scraper is connected inside the housing, and the upper end of the scraper contacts the bottom end of the filter screen.

[0013] Preferably, the scraper includes a groove seat, which is fixedly connected to the housing. A second movable plate is slidably connected to the groove seat. A plurality of second springs are connected at equal intervals along the length direction at the bottom end of the second movable plate. One end of each second spring is fixedly connected to the groove seat. An elastic scraping tooth is connected to the upper end of the second movable plate, and the elastic scraping tooth contacts the bottom end of the filter screen.

[0014] Preferably, the housing is connected to an air dispersing mechanism, which includes a second support frame fixedly connected to the housing. An air pump is fixedly connected to the upper end of the second support frame. The outlet end of the air pump is connected to a third connecting pipe. One end of the third connecting pipe extends into the housing and is connected to a hollow column. The hollow column is located in the middle of a plurality of atomizing nozzles. Air jets are evenly spaced along the axis of the hollow column.

[0015] Preferably, each of the jet nozzles is inclined downward toward the inner wall of the housing.

[0016] The dust suppression device for synthetic mica processing proposed in this invention has the following advantages:

[0017] 1. The dust gas is dispersed by a perforated plate and then introduced into different flushing chambers. The dust gas in each flushing chamber is in contact with the atomized spray liquid. The dust gas is dispersed in several flushing chambers and then atomized and sprayed. The dust gas and the atomized spray liquid are in uniform contact, which improves the dust removal effect.

[0018] 2. As the first movable plate moves downward, the through hole on the movable plate slides along the sealing rod until the two are completely separated. The accumulated spray liquid is discharged through the through hole, and the movable plate begins to rebound and rise. When the sealing rod is reinserted into the through hole, the drainage channel is sealed, and the dust-laden gas inside the housing will not escape through the drainage pipe, thereby effectively maintaining the dust removal efficiency of the system and improving the treatment effect of dust gas.

[0019] 3. After the geared motor is powered on and started, it drives the filter screen to rotate. When the misty gas comes into contact with the rotating filter screen, the water mist in it is effectively filtered, the water mist content in the gas is significantly reduced, and the water content of the gas discharged from the exhaust pipe is reduced, thereby improving the quality of the working environment.

[0020] 4. After the air pump is powered on and started, it draws in external air. The drawn air is introduced into the hollow column through the third connecting pipe. The gas in the hollow column is released from different jet nozzles. The released gas blows the atomized spray liquid released by the atomizing nozzle, so that the atomized spray liquid is dispersed and released, reducing the formation of liquid and improving the atomization effect.

[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] Example 1: Referring to Figures 1-6, a dust suppression device for synthetic mica processing includes a housing 1, a base 2 fixedly connected to the bottom of the housing 1, an air pump 3 for guiding air connected to the housing 1, a discharge pipe 4 connected to one side of the top of the housing 1, a drain pipe 6 connected to the bottom of one side of the housing 1, a perforated plate 5 connected inside the housing 1, a fixed column 7 fixedly connected to the bottom of the inside of the housing 1, one end of the fixed column 7 passing through the perforated plate 5, a plurality of dispersion plates 8 connected at equal intervals along the axial direction on the fixed column 7, the plurality of dispersion plates 8 being located at the upper end of the perforated plate 5, a plurality of flushing chambers 9 being provided between the plurality of dispersion plates 8 and the housing 1, a plurality of buffer teeth 10 being connected at equal intervals along the length direction on both sides of each dispersion plate 8, and a spraying mechanism 11 for spraying dust gas connected to the housing 1.

[0032] Referring to Figure 6, the spraying mechanism 11 includes a first support frame 111, which is fixedly connected to the housing 1. A liquid pump 112 is fixedly connected to the upper end of the first support frame 111. The outlet end of the liquid pump 112 is connected to a first connecting pipe 113. One end of the first connecting pipe 113 is connected to a filter element 114. The upper end of the filter element 114 is connected to a second connecting pipe 115. One end of the second connecting pipe 115 extends into the housing 1 and is connected to a circular annular pipe 116. The bottom end of the circular annular pipe 116 is connected to a plurality of atomizing nozzles 117 at equal intervals along the axial direction. The atomizing nozzles 117 are located above the dispersing plate 8.

[0033] Referring to Figure 6, the filter element 114 includes an open bucket 1141, the bottom end of which is connected to a first connecting pipe 113, a filter screen 1143 is fixedly connected inside the open bucket 1141, and a sealing cap 1142 is sealed to the opening of the open bucket 1141, with the upper end of the sealing cap 1142 connected to a second connecting pipe 115.

[0034] Working principle:

[0035] The air pump 3 is connected to the outlet of the crusher through a dust removal pipe. After starting, it can extract the dust generated during the crushing process, effectively preventing the dust from spreading to the external environment and ensuring the cleanliness and safety of the workplace. The extracted dust enters the housing 1 with the airflow. As the dust-laden gas is continuously introduced, the gas in the housing 1 comes into contact with the perforated plate 5. The perforated plate 5 evenly disperses the dust-laden gas to improve the efficiency of subsequent spray dust removal and avoid local dust accumulation that affects the treatment effect. The dispersed dust-laden gas enters different rinsing chambers 9. The dispersion plate 8 buffers and slows down the gas entering the rinsing chamber 9, prolonging the contact time between the dust and the atomized water, thereby enhancing the dust removal effect.

[0036] Simultaneously, after the liquid pump 112 is powered on and started, it draws external spray water and introduces it into the open tank 1141 through the first connecting pipe 113. As the spray water is continuously injected, the open tank 1141 is gradually filled. The filter screen 1143 filters the spray water in the tank to prevent impurities from clogging the atomizing nozzles 117 and ensure their stable operation. The filtered spray water enters the annular pipe 116 through the second connecting pipe 115 and is atomized and sprayed out from multiple atomizing nozzles 117. The atomized spray water flows downward and comes into counter-current contact with the dust-laden gas flowing upward in the flushing chamber 9 to achieve spray dust removal. The fine water mist mixes fully with the dust, improving the dust capture efficiency and effectively reducing the particulate matter content in the gas. The treated gas rises to the upper part of the shell 1 and is finally discharged through the discharge pipe 4.

[0037] The dust gas is dispersed by the perforated plate 5 and then introduced into different flushing chambers 9. The dust gas in each flushing chamber 9 is in contact with the atomized spray liquid. The dust gas is dispersed in several flushing chambers 9 and then atomized and sprayed. The dust gas and the atomized spray liquid are in uniform contact, which improves the dust removal effect.

[0038] The atomized spray in the rinsing chamber 9 passes through the perforated plate 5 and gathers at the bottom inside the housing 1. The liquid at the bottom inside the housing 1 is released from the drain pipe 6.

[0039] Example 2: The atomized spray liquid accumulates at the bottom of the interior of the housing 1 and is released from the drain pipe 6. The bottom of the interior of the housing 1 is in an open state, which causes some of the dust gas inside the housing 1 to be released from the drain pipe 6, reducing the dust gas treatment effect. Referring to Figures 3-5, as another preferred embodiment of the present invention, the difference from Example 1 is that the bottom of the perforated plate 5 is connected to a gap discharge mechanism 12. The gap discharge mechanism 12 includes a first spring 121. One end of the first spring 121 is connected to the bottom of the perforated plate 5, and the other end of the first spring 121 is fixedly connected to a first movable plate 122. The first movable plate 122 cooperates with the housing 1. A plurality of through holes 123 are equally spaced along the axis direction on the first movable plate 122. A plurality of sealing rods 124 are equally spaced along the axis direction at the bottom of the perforated plate 5. One end of each sealing rod 124 is sealed and inserted into the corresponding through hole 123. A plurality of first springs 121 are provided and are equally spaced along the axis direction of the perforated plate 5.

[0040] The atomized spray liquid released from the bottom of the flushing chamber 9 passes through the perforated plate 5 and accumulates on the upper end of the first movable plate 122. As the spray liquid continues to accumulate, its weight gradually increases. When the weight of the spray liquid exceeds the critical value, the first movable plate 122 is squeezed downward and the first spring 121 is stretched to generate elastic force. During the downward movement, the through hole 123 on the movable plate slides along the sealing rod 124 until the two are completely separated. At this time, the accumulated spray liquid is discharged through the through hole 123 and falls into the bottom of the housing 1.

[0041] As the spray liquid continues to be discharged, the amount of liquid at the upper end of the first movable plate 122 gradually decreases, and the pressure it receives decreases accordingly. When the elastic force of the first spring 121 exceeds the liquid pressure, the movable plate begins to rebound and rise. When the sealing rod 124 is reinserted into the through hole 123, the drainage channel is sealed, and the spray liquid stops being discharged. This ensures that during the spray liquid discharge process, the dust-laden gas inside the housing 1 will not escape through the drainage pipe 6, thereby effectively maintaining the dust removal efficiency of the system and improving the treatment effect of dust gas.

[0042] Example 3: When the dust gas inside the housing 1 is sprayed with a spraying liquid for dust removal, the treated gas contains water mist. The water mist is released from the discharge pipe 4 along with the gas. The water mist will reduce the quality of the working environment. Referring to Figures 7-8, as another preferred embodiment of the present invention, the difference from Example 1 is that a dehumidification mechanism 13 is connected to the upper end of the housing 1. The dehumidification mechanism 13 includes a geared motor 131, which is fixedly connected to the upper end of the housing 1. The output end of the geared motor 131 extends into the housing 1 and is fixedly connected to a filter screen 132. A scraper 133 is connected inside the housing 1, and the upper end of the scraper 133 contacts the bottom end of the filter screen 132.

[0043] The scraper 133 includes a groove seat 1331, which is fixedly connected to the housing 1. A second movable plate 1332 is slidably connected to the groove seat 1331. A plurality of second springs 1334 are connected at equal intervals along the length direction at the bottom end of the second movable plate 1332. One end of each second spring 1334 is fixedly connected to the groove seat 1331. An elastic scraper tooth 1333 is connected to the upper end of the second movable plate 1332. The elastic scraper tooth 1333 contacts the bottom end of the filter screen 132.

[0044] After the geared motor 131 is powered on and started, it drives the filter screen 132 to rotate. When the mist-containing gas comes into contact with the rotating filter screen 132, the water mist in it is effectively filtered.

[0045] At the same time, the rebound force generated by the second spring 1334 pushes the second movable plate 1332 to move upward. Under the guiding and limiting action of the groove seat 1331, the second movable plate 1332 maintains stable movement and drives the elastic scraper teeth 1333 to stick to the bottom of the filter screen 132 to scrape off the accumulated water droplets, effectively maintaining the air permeability of the filter screen 132.

[0046] After being filtered by the filter disc 132, the water mist content in the gas is significantly reduced, and the water content of the gas discharged from the exhaust pipe 4 is reduced, thereby improving the quality of the working environment.

[0047] Example 4: When the atomized spray liquid is released through the atomizing nozzle 117 to remove dust from the dust gas, the water mist is easy to accumulate and form water droplets, which reduces the atomization effect of the spray liquid. Referring to Figure 2, as another preferred embodiment of the present invention, the difference from Example 1 is that the housing 1 is connected to an air dispersing mechanism 14. The air dispersing mechanism 14 includes a second support frame 141, which is fixedly connected to the housing 1. An air pump 142 is fixedly connected to the upper end of the second support frame 141. The outlet end of the air pump 142 is connected to a third connecting pipe 143. One end of the third connecting pipe 143 extends into the housing 1 and is connected to a hollow column 144. The hollow column 144 is located in the middle of a plurality of atomizing nozzles 117. Air jets 145 are evenly spaced along the axis of the hollow column 144. Each air jet 145 is inclined downward toward the inner wall of the housing 1.

[0048] After the air pump 142 is powered on and started, it draws in external air. The drawn air is introduced into the hollow column 144 through the third connecting pipe 143. The gas in the hollow column 144 is released from different jet nozzles 145. The released gas blows the atomized spray liquid released by the atomizing nozzle 117, so that the atomized spray liquid is dispersed and released, reducing the formation of liquid and improving the atomization effect.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
