Description

Technical Field

[0001] The invention belongs to the field of gas filtration, in particular to a glue processing gas filtration device. Background Art

[0002] As an adhesive, glue is often used in manufacturing processes such as automobile parts processing. Organic solvents such as toluene, xylene and ethyl acetate in the glue processing process will evaporate during heating and other steps to produce organic waste gas. If these organic waste gases are directly discharged without treatment, they will cause serious harm to the environment and human health. In the glue processing process, activated carbon is often used to filter the gas, which can filter out volatile organic compounds and odorous substances in the gas.

[0003] A patent document with publication number CN214261261U discloses an environmentally friendly waste gas treatment device for glue processing, including a box body, a base and a filter box. A heating wire and an ultraviolet lamp are provided in the treatment box, and an activated carbon filter is provided in the filter box. The organic gas molecules in the waste gas are adsorbed by the activated carbon filter, diatomaceous earth filter and anthracite filter to avoid polluting the environment.

[0004] There are still some problems in the practical application of the above scheme. In the process of using activated carbon to filter gas, due to factors such as gas scouring, the activated carbon particles will fall off. If these activated carbon particles are not collected, the activated carbon particles will be discharged with the gas, which not only directly affects the filtering quality of the gas, but also there is a problem of wasted activated carbon particles.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1

[0037] like Figure 1-5 As shown, a glue processing gas filtering device according to an embodiment of the present invention comprises a processing chamber 1, wherein an air inlet 11 and an air outlet 12 are respectively provided at two ends of the processing chamber 1, and a cavity for the glue processing gas to pass through is provided inside the processing chamber 1, and an activated carbon filter assembly 2 is provided inside the processing chamber 1, and further comprises a collecting mechanism 3 and a control mechanism 4: the collecting mechanism 3 is used to collect activated carbon particles in the gas;

[0038] The collecting mechanism 3 comprises: a rotating rod 31 rotatably arranged in the processing chamber 1; an intercepting filter 32 fixedly connected to the rotating rod 31, the intercepting filter 32 being located inside the processing chamber 1; a collecting bin 33 arranged at the bottom of the processing chamber 1, the top of the collecting bin 33 being connected to the processing chamber 1; a collecting filter 34 rotatably arranged at the top of the collecting bin 33, the collecting filter 34 respectively sealing the top of the collecting bin 33 and the processing chamber 1 after rotating back and forth;

[0039] The activated carbon filter assembly 2 , the intercepting filter 32 and the collecting filter 34 are sequentially distributed along the gas flow direction, and the control mechanism 4 is used to control the rotation of the rotating rod 31 .

[0040] Specifically, the air inlet 11 and the air outlet 12 are respectively arranged at the left and right ends of the treatment chamber 1. The activated carbon filter assembly 2 can adopt an activated carbon filter structure. The activated carbon filter includes a shell and an activated carbon filler. The shell is fixed in the cavity of the treatment chamber 1. The interception filter 32 includes a filter frame. The filter frame is provided with a filter. The shape of the filter frame is consistent with the cavity inside the treatment chamber 1. The collection bin 33 is used to collect the activated carbon particles that fall off. If needed, a discharge port can be provided at the bottom end of the collection bin 33 to take out the activated carbon particles in the collection bin 33. The shape of the interception filter 32 and the opening shape at the top of the collection bin 33 are consistent with the cavity inside the treatment chamber 1. The initial state is as follows Figure 2 As shown, the intercepting filter 32 is perpendicular to the length direction of the cavity of the processing chamber 1, and the intercepting filter 32 seals the inside of the processing chamber 1, so that the gas inside the processing chamber 1 is in contact with the intercepting filter 32; and the collecting filter 34 is in a horizontal state, and the collecting filter 34 is flush with the inner bottom wall of the processing chamber 1, and the top of the collecting bin 33 is sealed to prevent the activated carbon particles inside the collecting bin 33 from being blown out.

[0041] When filtering the glue processing gas, the gas is introduced into the processing chamber 1 from the air inlet 11, and the gas flows from left to right inside the processing chamber 1, and passes through the activated carbon filter component 2 and the interception filter 32 in sequence, and the gas is filtered by the activated carbon filter component 2 to filter out volatile organic compounds such as benzene and ethyl acetate in the gas, and adsorb odorous substances in the gas; during the filtering process, due to factors such as the scouring of the flowing gas, the activated carbon particles will fall off, and the fallen activated carbon particles will flow to the interception filter 32 with the gas, and these activated carbon particles will be intercepted by the interception filter 32, so that the gas is filtered for the second time, and the gas after the second filtration is discharged through the air outlet 12, so that the work of filtering the glue processing gas is completed, and the quality of the gas discharged after filtration is improved by collecting the fallen activated carbon particles;

[0042] After working for a period of time, more activated carbon particles are attached to the side of the interception filter 32 close to the air inlet 11, which will affect the normal operation of the interception filter 32 and the normal flow of gas. The interception filter 32 needs to be cleaned. When cleaning, the collection filter 34 is rotated upward. Figure 2 In the figure, the collecting filter 34 rotates clockwise, so that the collecting filter 34 becomes vertical, and the intercepting filter 32 is started to rotate. During the rotation of the intercepting filter 32, the flowing gas can back-blow and clean the intercepting filter 32. At the same time, the activated carbon particles on the intercepting filter 32 are also thrown outward under the action of centrifugal force, thereby playing the function of cleaning the intercepting filter 32.

[0043] The activated carbon particles blown off and thrown out flow to the collection filter 34 with the gas, and the activated carbon particles are intercepted on the left side of the collection filter 34, and fall into the collection bin 33 under the action of gravity. After the interception filter 32 is cleaned, the interception filter 32 is restored to the initial state and fixed, and the interception filter 32 continues to intercept the activated carbon particles in the gas. Then, the collection filter 34 is rotated counterclockwise, and the collection filter 34 rotates to the lower left to send the activated carbon particles attached to the left side of the collection filter 34 to the collection bin 33, and the top of the collection bin 33 is sealed to prevent the activated carbon particles inside the collection bin 33 from flowing back into the processing chamber 1. In this way, the function of collecting activated carbon particles is completed, so that the activated carbon particles can be recycled and reused, and the problem of activated carbon particles being wasted after being discharged with the gas is improved. Repeat the above work, which can be recycled, and the function of online interception and collection of activated carbon particles in the gas filtration process is realized, without stopping the machine for processing, which improves work efficiency.

[0044] like Figure 1-3 As shown, the rotating rod 31 is located at the center of the intercepting filter 32, and a sealing device is provided at the connection between the rotating rod 31 and the processing chamber 1.

[0045] like Figure 2-7 As shown, the rotating rod 31 extends to the outside of the processing chamber 1, and the control mechanism 4 includes: a driving rod 41 slidably arranged on the outside of the processing chamber 1, and the driving rod 41 is coaxial with the rotating rod 31; a matching groove 411 corresponding to the rotating rod 31 is arranged at the end of the driving rod 41, and after the driving rod 41 moves and the end of the rotating rod 31 is inserted into the matching groove 411, the rotating rod 31 is fixed in the processing chamber 1.

[0046] Specifically, the top end of the rotating rod 31 extends above the processing chamber 1, and a matching groove 411 is provided at the bottom of the driving rod 41, and the driving rod 41 can move up and down. A power system for driving the driving rod 41 to move up and down is provided on the outside of the processing chamber 1. The power system can be hydraulically driven or cylinder driven.

[0047] After the driving rod 41 moves downward, the matching groove 411 is sleeved on the top of the rotating rod 31, and the friction between the ring side wall of the matching groove 411 and the ring side of the rotating rod 31 can decelerate the rotating rod 31 until the rotating rod 31 is stationary. It should be noted that after the driving rod 41 moves downward, the inner top wall of the matching groove 411 presses the top of the rotating rod 31, which can further press the rotating rod 31, so that the rotating rod 31 remains fixed, and the interception filter 32 maintains a stable position inside the processing chamber 1. After the driving rod 41 moves upward, it is separated from the rotating rod 31, and the gas in the processing chamber 1 can blow the interception filter 32 to rotate without the restraint of the driving rod 41.

[0048] like Figure 2-6 As shown, the control mechanism 4 also includes: a positioning groove 42 provided on the side wall of the processing chamber 1; a groove 43 provided on the outer side wall of the intercepting filter 32; a positioning rod 44 movably inserted in the groove 43, and the positioning rod 44 is inserted into the positioning groove 42 after moving outward.

[0049] Specifically, the groove 43 is arranged on the top side wall of the filter frame in the intercepting filter 32, and the two ends of the tension spring 441 are respectively connected to the groove 43 and the positioning rod 44. The tension spring 441 is used to pull the positioning rod 44 to shrink in the groove 43. The movement of the positioning rod 44 toward the outside of the filter frame is outward movement, and vice versa is inward movement. The positioning groove 42 is arranged on the top wall of the processing chamber 1. In the initial state, the positioning rod 44 is aligned with the positioning groove 42 up and down. During the downward movement of the driving rod 41, the friction between the matching groove 411 and the rotating rod 31 gradually slows down the rotating rod 31. When the rotating rod 31 and the intercepting filter 32 rotate slowly, the positioning rod 44 can be moved up and inserted into the positioning groove 42, so that the intercepting filter 32 is fixed and the intercepting filter 32 returns to its initial state. By setting the positioning rod 44, the position stability of the rotating rod 31 and the intercepting filter 32 can be further improved. At the same time, the intercepting filter 32 is in a state of sealing the inside of the processing chamber 1 when it is stationary, so as to ensure that the intercepting filter 32 can normally intercept the activated carbon particles in the gas.

[0050] like Figure 2-6 As shown, the processing chamber 1 is made of non-magnetic material, and the control mechanism 4 also includes: a tension spring 441 arranged on the intercepting filter 32 for driving the positioning rod 44 away from the positioning groove 42; a first magnetic block 442 fixedly connected to the end of the positioning rod 44; and a second magnetic block 412 fixedly connected to the driving rod 41. After the driving rod 41 approaches the processing chamber 1, the second magnetic block 412 and the first magnetic block 442 are attracted to each other and drive the positioning rod 44 to be inserted into the positioning groove 42.

[0051] Specifically, in the initial state, the driving rod 41 is located at the bottom of its moving range. At this time, the second magnetic block 412 is close to the first magnetic block 442 and is attracted to the first magnetic block 442, and the magnetic attraction force is greater than the force of the tension spring 441, and drives the positioning rod 44 to move upward and insert into the positioning groove 42, thereby fixing the intercepting filter 32; when cleaning the intercepting filter 32, the driving rod 41 moves upward, the second magnetic block 412 moves away from the first magnetic block 442, the magnetic attraction force becomes smaller, and the tension spring 441 pulls the positioning rod 44 downward, so that the positioning rod 44 is separated from the positioning groove 42 and shrinks in the groove 43, and then, the gas flowing in the processing chamber 1 can blow the intercepting filter 32 to rotate.

[0052] It should be noted that the first magnetic block 442 and the second magnetic block 412 are respectively located on the inner and outer sides of the processing chamber 1. The magnetic field between the two passes through the side wall of the processing chamber 1, and there is a situation where the magnetic attraction force is weakened. In order to improve the adsorption effect between the first magnetic block 442 and the second magnetic block 412 and ensure that the positioning rod 44 is smoothly inserted into the positioning groove 42, the positioning groove 42 can be set to pass through the top wall of the processing chamber 1. A magnetic transfer component is fixed in the positioning groove 42, and the top of the magnetic transfer component extends to the top of the processing chamber 1. The magnetic transfer component can be made of a magnet or a magnetic conductive material. After the driving rod 41 moves downward, the second magnetic block 412 contacts the magnetic transfer component to magnetize the magnetic transfer component or enhance the magnetic force of the magnetic transfer component, so that the magnetic transfer component is attracted to the first magnetic block 442. In this setting, the magnetic transfer component is closer to the first magnetic block 442, and the magnetic attraction force is better, which improves the above-mentioned problem.

[0053] like Figure 1-8 As shown, it also includes a guide mechanism 5, which includes: a support 51 fixedly connected to the outside of the treatment chamber 1; a guide plate 52 slidably arranged inside the support 51, and the guide plate 52 is located between the activated carbon filter assembly 2 and the interception filter 32. After the guide plate 52 moves to the inside of the treatment chamber 1, the gas flowing inside the treatment chamber 1 contacts the eccentric part of the interception filter 32 and drives the interception filter 32 to rotate.

[0054] Specifically, in order to improve the filtering effect of the activated carbon component on the gas, the gas generally flows to the activated carbon component in a comprehensive and uniform manner so that the gas can be in uniform contact with the activated carbon particles. However, when cleaning the interception filter 32, this comprehensive and uniform airflow will also be in comprehensive and uniform contact with the interception filter 32. The parts of the interception filter 32 located on the front and rear sides of the rotating rod 31 are in uniform contact with the airflow at the same time. This contact will affect the rotation of the interception filter 32, and then affect the backwash cleaning and centrifugal cleaning of the interception filter 32; in order to improve this problem, a guide plate 52 is provided, and the support 51 is provided on the rear side of the processing chamber 1. Initially, the guide plate 52 is retracted in the support 51, and the guide plate 52 is not inserted into the cavity of the processing chamber 1 to avoid interference with the airflow. The airflow can flow in a comprehensive and uniform manner inside the cavity, and the problem of aggravating the force loss of the guide plate 52 due to the airflow being in constant contact with the guide plate 52 can be avoided; before cleaning the interception filter 32, move the guide plate 52 so that the guide plate 52 is inserted into the cavity. Figure 2 It is shown that the guide plate 52 moves from the back to the front, and the front end of the guide plate 52 moves to the front side of the rotating rod 31, so that the airflow mainly contacts the part of the intercepting filter 32 located in the front side of the rotating rod 31, which can better blow the intercepting filter 32 to rotate, thereby ensuring that the cleaning work of the intercepting filter 32 is carried out smoothly.

[0055] like Figure 2 As shown, the guide plate 52 is arranged in an inclined shape with respect to the processing chamber 1 , and a notch is provided on the side wall of the processing chamber 1 for the guide plate 52 to pass through, and the guide plate 52 is sealed and matched with the notch.

[0056] Specifically, the notch is arranged on the rear wall of the processing chamber 1. Compared with the vertical design between the guide plate 52 and the processing chamber 1, the inclined guide plate 52 can play the role of drainage and force unloading. The guide plate 52 always seals the notch during the movement to prevent the gas in the processing chamber 1 from flowing out through the notch.

[0057] like Figure 2-10 As shown, the guide mechanism 5 also includes: a receiving groove 521 arranged in the guide plate 52 and close to the side of the intercepting filter 32; the support plate 53 arranged in the receiving groove 521 is rotated, and the guide plate 52 moves to the inside of the processing chamber 1, and the support plate 53 rotates and opens to abut against the inner wall of the processing chamber 1.

[0058] Specifically, after the guide plate 52 is inserted into the cavity of the processing chamber 1, the gas is blown onto the guide plate 52. The scouring force generated by the gas is mainly concentrated in the contact part between the guide plate 52 and the notch. There is a place where the force on the guide plate 52 is concentrated, which can easily cause the guide plate 52 to deform or even break. In order to improve this problem, a support plate 53 is provided on the guide plate 52. The support plate 53 is located on the side of the guide plate 52 away from the air inlet 11. The front end of the support plate 53 is rotatably connected to the guide plate 52. Initially, the support plate 53 is retracted inside the storage groove 521 so that the guide plate 52 can be smoothly inserted into the cavity. Then, the support plate 53 is rotated so that the rear end of the support plate 53 is against the rear wall of the processing chamber 1. In this way, the support plate 53, the guide plate 52 and the rear wall of the processing chamber 1 form a triangular structure, which plays a role in sharing the force on the guide plate 52 and extending the service life of the guide plate 52.

[0059] like Figure 3-10 As shown, the support 51 is made of non-magnetic material, and the flow guide mechanism 5 also includes: a third magnetic block 54 fixedly connected to the support plate 53; a magnetic conductive plate 55 embedded in the flow guide plate 52; a main magnet 56 slidably arranged in the support 51, and the main magnet 56 contacts the magnetic conductive plate 55 after movement to magnetize the magnetic conductive plate 55. After magnetization, the magnetic conductive plate 55 repels the third magnetic block 54 and pushes the support plate 53 to rotate and open.

[0060] Specifically, the main magnet 56 is located on the left side of the guide plate 52, and the magnetic force of the main magnet 56 is greater than the magnetic force of the third magnetic block 54. Initially, the main magnet 56 is away from the guide plate 52, and the support plate 53 is contracted in the storage groove 521 under the suction of the magnetic plate 55 and the third magnetic block 54. At this time, the magnetic plate 55 is partially located in the cavity and partially located in the support 51. When cleaning the interception filter 32, the guide plate 52 is inserted into the cavity, and the main magnet 56 is moved to the right. After the magnet 56 contacts the magnetic plate 55, the magnetic plate 55 is magnetized. After being magnetized, the magnetic plate 55 repels the third magnetic block 54, thereby pushing the support plate 53 to rotate and open, so that the rear side end of the support plate 53 is against the rear wall of the processing chamber 1; after the interception filter 32 is cleaned, the main magnet 56 is moved to the left, and the support plate 53 rotates under the suction force of the magnetic plate 55 and the third magnetic block 54 and retracts into the storage groove 521, so that the guide plate 52 can move backward and reset.

[0061] Embodiment 2

[0062] like Figure 3-9As shown, compared with Example 1, another implementation of the present invention is: the control mechanism 4 also includes: a first spring 45 and a second spring 46 arranged in the support 51, the first spring 45 is used to drive the guide plate 52 away from the cavity of the processing chamber 1, and the second spring 46 is used to drive the main magnet 56 away from the guide plate 52; a push rod 47 slidingly arranged in the support 51, the push rod 47 is fixedly connected to the driving rod 41; a first push plate 48 and a second push plate 49 fixedly connected to the push rod 47, the first push plate 48 and the second push plate 49 are staggered, after the push rod 47 moves, the guide plate 52 is pushed to be inserted into the interior of the processing chamber 1 by the first push plate 48, and the main magnet 56 is pushed close to the guide plate 52 by the second push plate 49.

[0063] Specifically, the two ends of the first spring 45 are connected to the support 51 and the guide plate 52 respectively, the two ends of the second spring 46 are connected to the support 51 and the main magnet 56 respectively, the push rod 47 can move up and down, and the driving rod 41 moves synchronously with the push rod 47. The first push plate 48 and the second push plate 49 are staggered up and down, and the first push plate 48 and the second push plate 49 are both inclined. The guide plate 52 and the main magnet 56 are respectively provided with convex rods. The first push plate 48 and the second push plate 49 respectively contact the convex rods to drive the guide plate 52 and the main magnet 56 to move. Initially, when the driving rod 41 is at the bottom of its moving range, the first spring 45 pulls the guide plate 52 to move backward, and the guide plate 52 shrinks in the support 51, and the second spring 46 pulls the main magnet 56 to move left, and the main magnet 56 is away from the guide plate 52.

[0064] After the driving rod 41 moves upward, it drives the push rod 47 to move upward. After the push rod 47 moves upward, the first push plate 48 first contacts the guide plate 52 and pushes the guide plate 52 forward. Then, the second push plate 49 contacts the main magnet 56 and pushes the main magnet 56 close to the guide plate 52. After the guide plate 52 moves forward and inserts into the cavity, the main magnet 56 contacts the magnetic plate 55. The magnetic plate 55 repels the third magnetic block 54, pushing the support plate 53 to rotate and open. The support plate 53 abuts against the rear wall of the processing chamber 1 to avoid the guide plate 52 from being subjected to concentrated force.

[0065] After the driving rod 41 moves downward, the second push plate 49 separates from the main magnet 56, the second spring 46 drives the main magnet 56 away from the guide plate 52, the third magnetic block 54 attracts the magnetic conductive plate 55, and the support plate 53 shrinks in the guide plate 52. Then, the first push plate 48 separates from the guide plate 52, and the first spring 45 drives the guide plate 52 to move backward and reset. The guide plate 52 moves out of the cavity, and the interception filter 32 can continue to intercept the activated carbon particles normally.

[0066] Working principle: Initially, the driving rod 41 moves downward, and the positioning rod 44 is inserted into the positioning groove 42, so that the interception filter 32 is fixed in the cavity of the processing chamber 1. When filtering the glue processing gas, the gas is introduced into the processing chamber 1 from the air inlet 11. The gas flows from left to right inside the processing chamber 1, and passes through the activated carbon filter component 2 and the interception filter 32 in sequence. The gas is filtered by the activated carbon filter component 2 to filter out volatile organic compounds such as benzene and ethyl acetate in the gas, and adsorb odorous substances in the gas; the activated carbon particles that fall off during the filtering process are intercepted by the interception filter 32, so that the gas is filtered for the second time, and the gas after the second filtering is discharged through the outlet 12. In this way, the work of filtering the glue processing gas is completed;

[0067] After working for a period of time, a large amount of activated carbon particles are attached to the side of the interception filter 32 close to the air inlet 11. When cleaning the interception filter 32, the collection filter 34 is rotated upward to make the collection filter 34 vertical, and the driving rod 41 is moved upward. The driving rod 41 drives the push rod 47 to move upward. After the push rod 47 moves upward, the first push plate 48 first contacts the guide plate 52 and pushes the guide plate 52 forward. Then, the second push plate 49 contacts the main magnet 56 and pushes the main magnet 56 close to the guide plate 52. After the guide plate 52 moves forward and inserts into the cavity, the main magnet 56 contacts the magnetic plate 55, and the magnetic plate 55 repels the third magnetic block 54, pushing the support plate 53 to rotate and open, and the support plate 53 is against the rear wall of the processing chamber 1 to avoid the guide plate 52 from being subjected to concentrated force; the front end of the guide plate 52 moves to the front side of the rotating rod 31, so that the airflow mainly contacts the part of the interception filter 32 located in the front side of the rotating rod 31;

[0068] After the driving rod 41 continues to move upward, it separates from the rotating rod 31, and the second magnetic block 412 moves away from the first magnetic block 442, the magnetic attraction between the two becomes smaller, and the tension spring 441 pulls the positioning rod 44 downward, so that the positioning rod 44 is separated from the positioning groove 42 and shrinks in the groove 43, and then, the gas flowing in the processing chamber 1 can blow the interception filter 32 to rotate. During the rotation of the interception filter 32, the flowing gas can both back-blow and clean the interception filter 32. At the same time, the activated carbon particles on the interception filter 32 will also be thrown outward under the action of centrifugal force, thereby playing the function of cleaning the activated carbon particles on the interception filter 32 and improving the cleanliness of the interception filter 32; the activated carbon particles blown off and thrown out flow to the collecting filter 34 with the gas, and the activated carbon particles are intercepted on the left side of the collecting filter 34 and fall into the collecting bin 33 under the action of gravity.

[0069] After the interception filter 32 is cleaned, the driving rod 41 is moved downward. After the driving rod 41 is moved downward, the friction between the matching groove 411 and the rotating rod 31 causes the rotating rod 31 to gradually slow down. When the rotating rod 31 and the interception filter 32 rotate slowly, the positioning rod 44 can be moved upward and inserted into the positioning groove 42, so that the interception filter 32 is fixed, and the interception filter 32 returns to its initial state and continues to intercept the activated carbon particles in the gas; then, the rotating collection filter 34 is rotated. After the collecting filter 34 rotates to the lower left, the activated carbon particles attached to the left side of the collecting filter 34 are sent to the collecting bin 33, and the top of the collecting bin 33 is sealed to prevent the activated carbon particles inside the collecting bin 33 from flowing back into the processing chamber 1. In this way, the function of collecting the activated carbon particles is completed. This cycle can be reused, and the function of online interception and collection of activated carbon particles in the gas filtration process is realized without stopping for processing, thereby improving work efficiency.
