Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, and in particular to an air filtering and purification system for a refractory material processing workshop. Background Art

[0002] A large amount of dust and harmful gases will be generated during the processing of refractory materials. These pollutants will not only pollute the environment, but also harm the health of workers. In order to ensure the cleanliness of the production environment and the health of workers, it is necessary to filter and separate the pollutants in the gas from the gas. In order to achieve this purpose, an air filtration and purification system is usually used. Its working principle is to extract gas through a fan and filter and separate the pollutants in the gas through a variety of filter media; the filtration part of the existing air filtration and purification system generally includes a primary filter, a medium filter, a HEPA filter and an activated carbon filter, among which the primary filter is used to filter large particle pollutants in the gas; the medium filter is used to filter medium-sized particles in the gas; the HEPA filter can filter particles larger than 0.3 microns in the gas, and the filtration efficiency is as high as 99.97% or more. Due to its developed pore structure and surface area, the activated carbon filter can adsorb a large amount of harmful gases and odor molecules, thereby achieving gas purification.

[0003] For example, a multi-layer purification filter device for a fresh air system disclosed in a Chinese patent with the authorization announcement number CN216653837U uses a filter layer and an activated carbon filter layer to separate pollutants from the gas. However, in this patent and the prior art, the oxygen-containing functional groups rich in the surface of the activated carbon filter element are easy to fall off and generate acetic acid in a wet oxygen environment, and various volatile organic compounds (VOCs) adsorbed on the surface of the activated carbon may also undergo complex chemical reactions under wet oxygen conditions to generate acetic acid. These factors together lead to the activated carbon filter element having a sour taste after being used for a period of time, and the purification system that produces the sour taste cannot guarantee the health of the workers in the processing workshop. The current equipment does not have an effective related setting to separate and process such sour taste, and cannot guarantee the air quality in the processing workshop, which affects the quality of the product and also affects the service life of the air purification system.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 12 As shown, an air filtration and purification system for a refractory material processing workshop provided by an embodiment of the present invention includes a housing 100 , a filter assembly 200 , an activated carbon filter 300 , a bracket 400 and an air extraction mechanism 600 .

[0040] The housing 100 is cylindrical, and an air intake grid 110 is provided on the peripheral wall thereof; a workbench 120 is fixedly connected to the lower portion thereof, and an inspection door 121 is installed on the workbench 120 .

[0041] The filter assembly 200 is fixedly connected to the shell 100 and is located inside the shell 100; the filter assembly 200 is used to filter solid particles in the gas; the filter assembly 200 includes a primary filter 210, a HEPA filter 220 and a support filter 230 arranged in sequence from the outside to the inside; the HEPA filter 220 is a prior art and will not be described in detail here.

[0042] The activated carbon filter 300 is coaxially fixedly connected to the housing 100 and is located inside the filter assembly 200 ; an annular processing chamber 310 is formed between the activated carbon filter 300 and the filter assembly 200 , and an exhaust chamber 320 is inside the activated carbon filter 300 .

[0043] The bracket 400 is installed in the shell 100; a cooling component is installed on the bracket 400, the cooling component is located in the processing chamber 310, and the cooling component is used to cool the gas in the processing chamber 310; a water storage bucket 410 is provided below the processing chamber 310, and the water storage bucket 410 is installed on the bracket 400.

[0044] The exhaust mechanism 600 is installed on the housing 100 , and is used to allow air to pass through the air inlet grid 110 , the filter assembly 200 , the processing chamber 310 , the activated carbon filter 300 and the exhaust chamber 320 in sequence before being discharged from the housing 100 .

[0045] When in use, the air extraction mechanism 600 is started, and the air extraction mechanism 600 pumps the external air from the air inlet grid 110 into the housing 100. The air entering the housing 100 passes through the filter assembly 200, and the particles in the air are filtered, separated, and adsorbed by the primary filter 210, the HEPA filter 220, and the support filter 230; the air then enters the processing chamber 310, is cooled by the cooling assembly, and the water vapor in the air condenses into liquid and falls into the water storage bucket 410. The air then passes through the activated carbon filter 300, and the organic impurities in the air are adsorbed by the activated carbon filter 300. The gas then enters the exhaust chamber 320 and is finally discharged from the housing 100, completing the filtering and purification of the air in the processing workshop, thereby improving the processing efficiency of the refractory material. When the liquid storage volume in the water storage bucket 410 reaches the preset value, the water storage bucket 410 is removed from the bracket 400, and after the liquid in the water storage bucket 410 is poured out, the water storage bucket 410 is restored to its original state. The present invention installs a cooling component in the processing chamber 310 between the filter component 200 and the activated carbon filter 300, so that the air is condensed into liquid before passing through the activated carbon filter 300 and stored in the water storage bucket 410, thereby reducing the humidity of the air passing through the activated carbon filter 300, thereby solving the problem of acetic acid generated by the shedding of oxygen-containing functional groups on the surface of the activated carbon filter 300 in a wet oxygen environment and affecting the health of workers, ensuring the purity of the air in the refractory material processing workshop and providing conditions for the production and processing of refractory materials.

[0046] In a further embodiment, Figure 6 As shown, the upper end of the bracket 400 is rotatably mounted on the housing 100; Figure 4 , Figure 5 , Fig. 9A plurality of mounting grooves 402 are provided on the bracket 400, and the mounting grooves 402 extend radially along the bracket 400; the cooling assembly includes a plurality of semiconductor radiators 500; the semiconductor radiators 500 are fixedly connected to the mounting grooves 402, and the semiconductor radiators 500 extend radially along the shell 100; the plurality of semiconductor radiators 500 are evenly distributed along the circumference of the processing chamber 310, and the processing chamber 310 is divided into a plurality of first chambers 311 and second chambers 312, and the first chambers 311 and the second chambers 312 are alternately distributed along the circumference of the shell 100; the cold surface of the semiconductor radiator 500 faces the first chamber 311, and the hot surface faces the second chamber 312; a water storage bucket 410 is installed at the lower part of each first chamber 311; the first chamber 311 is connected to the first exhaust pipe 323, and the second chamber 312 is connected to the second exhaust pipe 324.

[0047] The air extraction mechanism 600 includes a first air extraction pump 610 and a second air extraction pump 620. The first air extraction pump 610 is connected to the first exhaust pipe 323; the second air extraction pump 620 is connected to the second exhaust pipe 324. Figure 2 .

[0048] When in use, the first vacuum pump 610 and the second vacuum pump 620 are started, and the first vacuum pump 610 pumps the gas outside the shell 100 into the shell 100 through the air intake grid 110. The gas enters the first cavity 311 after being filtered by the filter assembly 200. The gas in the first cavity 311 contacts the cold surface of the semiconductor radiator 500, and the water vapor in the gas is condensed to form liquid, and then enters the water storage bucket 410 at the bottom of the first cavity 311; the air with low humidity contacts the activated carbon filter 300, and the activated carbon filter 300 adsorbs the organic matter therein, and the air passes through the activated carbon filter 300 and is discharged into the room through the first exhaust pipe 323.

[0049] The second vacuum pump 620 pumps the gas outside the shell 100 into the shell 100 through the air intake grid 110. The gas enters the second chamber 312 after being filtered by the filter assembly 200, and then contacts the activated carbon filter 300. The activated carbon filter 300 adsorbs the organic impurities therein and discharges them to the outside through the second exhaust pipe 324.

[0050] After a period of use, the bracket 400 is rotated to a preset angle, so that the activated carbon filter 300 originally in contact with the first cavity 311 is in contact with the second cavity 312, and the activated carbon filter 300 originally in contact with the second cavity 312 is in contact with the first cavity 311; at this time, the first cavity 311 continues to cool the air therein, completes the condensation of water vapor in the air, and reduces the humidity of the air in the first cavity 311, while the air in the second cavity 312 is in contact with the hot surface of the semiconductor radiator 500, and the gas in contact with the activated carbon filter 300 is at a higher temperature, which can make At this time, the volatile organic matter on the activated carbon filter 300 in contact with the second chamber 312 is detached, and then the detached impurities are discharged to the outside with the air through the second exhaust pipe 324; thereby avoiding the volatile organic matter adsorbed on the surface of the activated carbon filter 300 to react chemically in a wet oxygen environment to produce acetic acid, further solving the problem of affecting the health of workers and the quality of product production due to the acidification of the activated carbon filter 300. At the same time, the volatile organic matter adsorbed on the activated carbon is reduced, and the service life of the activated carbon filter 300 is extended to a certain extent.

[0051] In a further embodiment, Figure 4 , Figure 5 , Figure 6 , Fig. 9 As shown, a plurality of partitions 330 are fixedly connected to the bracket 400, and the plurality of partitions 330 are evenly distributed along the circumference of the bracket 400, and the partitions 330 extend along the radial direction of the bracket 400, and the partitions 330 are arranged one-to-one with the semiconductor heat sink 500, and the partitions 330 and the corresponding semiconductor heat sink 500 are located in the same radial direction in the vertical projection; the plurality of partitions 330 divide the exhaust cavity 320 into a plurality of first exhaust channels 321 and second exhaust channels 322, and the first exhaust channels 321 and the second exhaust channels 322 are alternately distributed, and the first exhaust channels 321 are set to be located inside the first cavity 311, and the second exhaust channels 322 are set to be located inside the second cavity 312; the first exhaust channel 321 connects the first cavity 311 and the first exhaust pipe 323, and the second exhaust channel 322 connects the second cavity 312 and the second exhaust pipe 324. The gas in the first chamber 311 passes through the activated carbon filter 300 and enters the first exhaust channel 321 , and then is discharged to the room through the first exhaust pipe 323 ; the gas in the second chamber 312 passes through the activated carbon filter 300 and enters the second exhaust channel 322 , and then is discharged to the outside through the second exhaust pipe 324 .

[0052] In a further embodiment, Figure 7 , Fig. 9 and Fig.11As shown, the water bucket 410 can be installed on the bracket 400 so as to move up and down within a preset range; the lower ends of the water bucket 410 on both sides of the circumference are provided with through water outlet holes 411; the water bucket 410 on both sides of the circumference are provided with mounting grooves 402; a ball 412 is slidably installed in the mounting groove 402; a limiting spring is connected between the water bucket 410 and the ball 412, and the limiting spring has a tendency to make the ball 412 extend out of the mounting groove 402; a limiting hole 401 is provided on the bracket 400, and in the initial state, the ball 412 extends out of the mounting groove 402 and is inserted into the limiting hole 401, and the water outlet hole 411 is blocked by the bracket 400, and after the water bucket 410 moves downward by a preset distance, the water outlet hole 411 extends out of the bracket 400; a reset spring 420 is connected between the water bucket 410 and the bracket 400.

[0053] The gravity of the water storage bucket 410 and the liquid inside makes the water storage bucket 410 tend to move downward. When the amount of liquid in the water storage bucket 410 is greater than a preset value, the gravity of the water storage bucket 410 and the liquid inside overcomes the elastic force of the return spring 420, and the water storage bucket 410 moves downward under the action of gravity. During the downward movement of the water storage bucket 410, the ball 412 moves along its own axis and gradually retracts into the installation groove 402, and the limit spring is compressed and stored; after the water storage bucket 410 moves a preset distance, the water outlet 411 extends out of the bracket 400, and the bracket 400 no longer blocks the water outlet 411, and the liquid in the water storage bucket 410 The liquid flows out through the water outlet 411. When the amount of liquid in the water storage bucket 410 is less than a preset value, the elastic force of the reset spring 420 is greater than the gravity of the water storage bucket 410 and the liquid therein, and the reset spring 420 causes the water storage bucket 410 to move upward. When the height of the ball 412 is consistent with the height of the limiting hole 401, the limiting spring releases the elastic force, so that the ball 412 is reinserted into the limiting hole 401, and the water storage bucket 410 returns to its initial height. During the drainage process of the water storage bucket 410, the condensed liquid in the first chamber 311 can still fall into the water storage bucket 410 under the action of gravity, and will not affect the normal operation of the filtration and purification.

[0054] In a further embodiment, Figure 7 , Fig. 9 , Fig.11 and Fig.12 As shown, the bracket 400 is connected with a driving assembly, and the driving assembly is used to drive the bracket 400 to rotate around its own axis at a preset angle after the water storage bucket 410 drains water. The driving assembly includes a guide rail 710 and a slide bar 700; the guide rail 710 is opened at the lower part of the housing 100, and the guide rail 710 includes a plurality of vertical guide grooves 711 and a plurality of oblique guide grooves 712 arranged alternately; the plurality of vertical guide grooves 711 and the plurality of oblique guide grooves 712 are connected end to end; the number of the vertical guide grooves 711 and the oblique guide grooves 712 is consistent with the number of the first chamber 311; the slide bar 700 is fixedly connected to the water storage bucket 410, and the slide bar 700 is slidably mounted on the guide rail 710; the plurality of water storage buckets 410 move up and down synchronously.

[0055] During use, the slide bar 700 is slidably installed in the guide rail 710. When the amount of liquid in a water storage bucket 410 is greater than a preset value, the gravity of the water storage bucket 410 and the liquid therein overcomes the elastic force of the return spring 420, and the water storage bucket 410 moves downward. At the same time, all the water storage buckets 410 move downward synchronously, and all the slide bars 700 slide in their corresponding vertical guide grooves 711 to discharge the liquid therein; when the gravity of the water storage bucket 410 and the liquid therein is equal to the elastic force of the return spring 420, the slide bar 700 is exactly located at the lowermost end of the vertical guide groove 711; thereafter, when the liquid in the water storage bucket 410 continues to flow out, the gravity of the two is less than the return spring 420. Due to the elastic force, the return spring 420 drives the water bucket 410 to move upward, and the slide bar 700 enters the oblique guide groove 712. As the water bucket 410 moves upward, the slide bar 700 slides from bottom to top in the oblique guide groove 712, thereby driving the bracket 400 to rotate around its own axis. When the slide bar 700 reaches the connection between the oblique guide groove 712 and the vertical guide groove 711, the rotation angle of the bracket 400 is equal to the center angle corresponding to the first cavity 311, so that the activated carbon filter 300 originally in contact with the first cavity 311 contacts with the second cavity 312, and the activated carbon filter 300 originally in contact with the second cavity 312 contacts with the first cavity 311, and then the filtering and drying work continues.

[0056] In a further embodiment, Fig.11 and Fig.12 As shown, the slide bar 700 is a telescopic rod, and a driving spring is arranged inside the slide bar 700, which makes the slide bar 700 tend to extend; the depth of the lower end of the vertical guide groove 711 is less than the depth of the lower end of the oblique guide groove 712; the depth of the upper end of the oblique guide groove 712 is less than the depth of the upper end of the vertical guide groove 711, and the depth of the vertical guide groove 711 gradually increases from top to bottom; the depth of the oblique guide groove 712 first increases, then decreases, and then increases again from bottom to top.

[0057] When the slide bar 700 moves downward in the vertical guide groove 711, the slide bar 700 gradually stretches and the driving spring gradually releases the elastic force; when the slide bar 700 moves to the connection between the vertical guide groove 711 and the oblique guide groove 712, since the driving spring has a tendency to continue to release the elastic force, the slide bar 700 automatically enters the deeper oblique guide groove 712; when the slide bar 700 slides in the oblique guide groove 712, the driving spring first stretches to its longest length, then compresses to its shortest length and then gradually stretches again. When the slide bar 700 moves to the connection between the oblique guide groove 712 and the vertical guide groove 711, the slide bar 700 automatically enters the deeper vertical guide groove 711. The present invention sets the depths of the vertical guide groove 711 and the oblique guide groove 712 to different depths, so that the slide rod 700 can move more smoothly in the vertical guide groove 711, the oblique guide groove 712 and the connection between the two, ensuring that the water storage bucket 410 can drive the bracket 400 to rotate around its own axis during the process of restoring the initial height after draining water, thereby changing the contact position between the activated carbon filter 300 and the first cavity 311 and the second cavity 312, thereby solving the problem that the activated carbon filter 300 produces acetic acid that affects the health of workers and the quality of product processing.

[0058] In a further embodiment, Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, at least one first fin plate 313 and at least one second fin plate 314 are fixedly connected to both sides of the first cavity 311 in the circumferential direction, respectively. The first fin plates 313 and the second fin plates 314 are alternately distributed from the inside to the outside, and an "S"-shaped airway is formed in the first cavity 311. As shown in the figure, the first fin plates 313 and the second fin plates 314 separate the first cavity 311, so that the flow path of the gas in the first cavity 311 is longer, and the contact area with the first fin plates 313 and the second fin plates 314 is larger, so that more heat exchange can be generated, and the water vapor in the gas is condensed into liquid more, and the humidity of the working environment of the activated carbon filter 300 is further reduced, so as to solve the problem that the activated carbon filter 300 becomes acidic and affects the health of workers and the processing quality of products.

[0059] In a further embodiment, Figure 5 , Fig. 9As shown, a plurality of heat conducting sheets 315 are arranged vertically at intervals in each second cavity 312, and both ends of the heat conducting sheets 315 are fixedly connected to the hot surface of the semiconductor heat sink 500, and the inner surface of the heat conducting sheets 315 is in contact with the outer surface of the activated carbon filter 300. Thus, the activated carbon filter 300 in contact with the second cavity 312 is heat-exchanged with the heat conducting sheets 315, so that the temperature of the activated carbon filter 300 in this part is increased, and the volatile substances on the activated carbon filter 300 are further separated, further avoiding the chemical reaction of the volatile substances in the wet oxygen environment to produce acetic acid, and through this method, the volatile organic substances adsorbed on the activated carbon are reduced, and the service life of the activated carbon filter 300 is further extended.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
