Description

Technical Field

[0001] The invention relates to the technical field of dust collectors, in particular to an air box pulse bag type dust collector with low emission concentration. Background Art

[0002] Dust collector is a widely used dust removal equipment. Dust collectors usually include bag dust collectors, pulse bag dust collectors, electric dust collectors and other types. Dust collectors are widely used in chemical, petroleum, metallurgy, construction, mining, machinery, textile and other industrial sectors, as well as various dust control occasions to reduce dust pollution and protect the environment.

[0003] Patent announcement number CN211635629U discloses a new type of air box pulse bag dust collector with low emission concentration, comprising two support frames, a hopper box fixedly installed between the tops of the two support frames, a rigid liquid impeller feeder fixedly installed at the bottom of the hopper box, a chain conveyor fixedly installed at the bottom of the rigid liquid impeller feeder, a dust removal box fixedly installed on the top of the hopper box, a connecting box fixedly installed between the two dust removal boxes, a top cover fixedly installed on the top of the dust removal box, guardrails fixedly installed on the opposite sides of the two dust removal boxes, and a pulse valve fixedly installed on the top of the guardrail. This new type of air box pulse bag dust collector with low emission concentration effectively improves the adsorption effect of the dust collector by setting a rigid liquid impeller feeder, allowing dust to be directly absorbed and no longer attached to the inside of the pulse valve, and improves the dust removal efficiency of the dust collector.

[0004] However, this device still has some shortcomings: this device effectively improves the dust adsorption effect and dust removal efficiency, but when the dust is input into the dust collector through the pipe without drying, the dust's own adhesion to the filter bag is enhanced due to the humidity, resulting in the compressed air ejected by the pulse valve. The removal effect of the dust trapped on the surface of the filter bag is reduced, and it is easy to aggravate the erosion of the dust on the filter bag. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides an air box pulse bag dust collector with low emission concentration, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an air box pulse bag dust collector with low emission concentration, comprising a support assembly, a device body is provided on the top of the support assembly, an inlet pipe is provided on the left side of the device body, a discharge assembly is provided at the bottom of the device body, a fan exhaust assembly is provided on the right side of the device body, a pulse valve assembly is provided on the left side of the top of the device body, and the pulse valve assembly passes through the interior of the device body, a filter plate frame is fixedly installed inside the device body, a filter bag assembly is fixedly installed inside the filter plate frame, and a V-shaped plate is provided on the left side of the bottom of the filter plate frame;

[0007] An anti-adhesion device is provided on the left side of the interior of the device body, an anti-missing device is provided on the periphery of the anti-adhesion device, and an anti-pollution device is provided inside the anti-missing device;

[0008] The anti-adhesion device includes an electric rotating rod, the bottom of which is rotatably mounted on the left side of the bottom inner wall of the device body, and a reciprocating spiral groove is opened on the upper part of the outside of the electric rotating rod, and a sliding plate is movably mounted on the outer wall of the reciprocating spiral groove of the electric rotating rod, and the left side of the sliding plate is slidably mounted on the left side of the inner wall of the device body. Two heating components are symmetrically and fixedly mounted on the bottom of the sliding plate, and an arc guide plate is hinged on the right side of the sliding plate by a torsion spring. Two fixed plates are symmetrical and fixedly mounted on the top of the sliding plate. A friction wheel is rotatably mounted on the side of the fixed plate away from the axis of the sliding plate, and a cross bar is fixedly mounted on the side of the friction wheel away from the fixed plate. A number of elastic retractable plates are equidistantly and fixedly mounted on the outer wall of the cross bar, and an arc plate is hinged at the edge of the outer wall of the fixed end of the elastic retractable plate, and a rejection plate is slidably mounted on the fixed end of the elastic retractable plate.

[0009] The outer wall of the ejector plate is hinged on the end of the arc plate near the cross bar, and the dust-laden gas is transported to the inside of the device body through the inlet pipe, and the wind turbine is arranged at the bottom of the device body to cause the dust-laden gas to surge upward inside the device body, and large particles of dust fall into the discharge assembly under the action of gravity, and fine dust is intercepted by the filter bag assembly and the filter plate frame during the upward surge, and the dust-free gas is discharged from the device body through the fan exhaust assembly. When the pressure difference inside the device body reaches a critical value, the pulse valve assembly is started and blows the filter bag assembly to make it expand, and the dust attached to the surface or inside of the filter bag assembly is blown off and falls into the discharge assembly. When the equipment is running, the electric rotating rod is turned on in advance, and when the electric rotating rod rotates along the bottom of the inner wall of the device body, the reciprocating spiral groove on its own outer wall restricts the built-in block of the sliding plate. When the movable rod rotates, the sliding plate can slide upward along the left inner wall of the device body and reset, and the sliding plate drives the heating component to move synchronously. At the same time, the sliding plate drives the curved guide plate to move synchronously. During the upward movement of the curved guide plate, its top curved surface contacts the inclined surface of the V-shaped plate and generates a resistance force, and the hinge shaft of the curved guide plate starts to rotate due to the resistance force and drives the curved guide plate to flip toward the left inner wall of the device body; when the sliding plate moves upward and resets, it drives the fixed plate to move synchronously, and the fixed plate drives the friction wheel to synchronously rub along the left inner wall of the device body through the friction force and drives the cross bar to rotate. When the cross bar drives the elastic telescopic plate to revolve, the curved surface of the elastic telescopic plate telescopic end is separated from the contact limit on the left inner wall of the device body, and the elastic end of the elastic telescopic plate is pulled by the spring to move away from the cross bar, and the curved plate drives the rejecting plate to slide synchronously along the fixed end of the elastic telescopic plate. When the curved surface of the elastic telescopic plate telescopic end contacts the inner wall of the device body again, it is reset by the resistance force, and so on.

[0010] The cam is hinged on the bottom of the L-shaped plate to prevent the cam from sliding back and forth, so that the cam can slide back and forth to the left of the L-shaped plate when the cam is in a stable position.

[0011] According to the above technical solution, the anti-missing device also includes a semicircular baffle, a hollow arc block, an L-shaped straight plate and an arc panel. The bottom of the semicircular baffle is slidably installed on the bottom of the inner wall of the device body, the back of the hollow arc block is fixedly installed on the front of the outer wall of the semicircular baffle, the back of the left end of the L-shaped straight plate is fixedly installed on the front of the L-shaped plate, and the front of the arc panel is fixedly installed on the front of the inner wall of the L-shaped straight plate.

[0012] According to the above technical solution, a spring is arranged between the bottom of the semicircular baffle and the device body, and the arc surface of the hollow arc block is located on the movement trajectory of the arc panel. When the L-shaped plate moves upward, it drives the L-shaped straight plate to move synchronously, and the L-shaped straight plate drives the arc panel to move synchronously. When the arc panel moves upward, its own arc surface will contact and resist the arc surface of the hollow arc block to generate a resistance thrust. At this time, the hollow arc block drives the semicircular baffle to slide along the bottom of the inner wall of the device body toward its back. When the arc panel passes over the hollow arc block, the semicircular baffle is reset by the spring, and this is repeated.

[0013] According to the above technical solution, the anti-pollution device includes a cam, a screw, a sliding ring, an L-shaped rod, a square frame and several diverter plates, the bottom of the cam is rotatably mounted on the bottom of the inner wall of the device body, the bottom of the screw is fixedly mounted on the top of the cam, the sliding ring passes through and is threadedly connected to the outer wall of the screw, the bottom of the right end of the L-shaped rod is fixedly mounted on the top of the arc panel, the left side of the top of the L-shaped rod is fixedly mounted on the right side of the outer wall of the sliding ring, the bottom of the square frame is slidably mounted on the outer wall of the guide plate through a spring, the front of the square frame is in contact with the outer wall of the cam, and a groove is provided at the bottom of the square frame, the bottoms of several diverter plates are hinged to the outer wall of the guide plate through a torsion spring, the top of the diverter plate is in contact with the inner wall of the square frame groove, and the arc panel When the cam rotates, it breaks away from the limit resistance of the square frame, and the square frame slides along the guide plate toward the front of the device body through the spring force. After the cam revolves one circle, it again resists the square frame and resets, and the spring forces the square frame to always stick to the outer wall of the cam. During the movement of the square frame, it resists the diverter plate through its own bottom groove, and the diverter plate causes its own hinge shaft to start rotating due to the resistance force. At this time, the diverter plate moves in an arc trajectory with the hinge shaft as the axis, and then the diverter plate is reset by the torsion spring.

[0014] According to the above technical solution, the anti-pollution device also includes a fixed rod, a hollow cleaning roller, a convex plate, a convex ball rod and an open-hole ring. Both ends of the fixed rod are fixedly installed inside the square frame, the inner wall of the hollow cleaning roller passes through and is rotatably installed on the outer wall of the fixed rod, the inside of the convex plate passes through and is fixedly installed at one end of the bottom of the fixed rod, the convex ball rod is arranged inside the hollow cleaning roller, and the inside of the open-hole ring is slidably installed inside the hollow cleaning roller through a spring.

[0015] According to the above technical solution, the outer wall of the hollow cleaning roller contacts the outer wall of the guide plate, and activated carbon particles are arranged inside the hollow cleaning roller, the arc surface of the raised part of the convex block plate is located on the movement trajectory of the convex ball rod, and the open hole ring passes through and is fixedly installed on the outer wall of the convex ball rod. During the sliding process of the square frame, the fixed rod is driven to move synchronously, and the fixed rod drives the hollow cleaning roller to slide and rub synchronously along the outer wall of the guide plate. The hollow cleaning roller starts to rotate along the outer wall of the fixed rod due to friction, and the hollow cleaning roller drives the open hole ring to rotate. During the process of the open hole ring driving the convex ball rod to rotate, the arc surface of the convex ball rod and the convex part of the convex block plate conflict with each other. The fixed rod limits the convex plate to prompt the convex ball rod to drive the open hole ring to move toward the inside of the hollow cleaning roller, and then the open hole ring is reset by the spring force and drives the convex ball rod to reset, and so on.

[0016] The present invention provides an air box pulse bag dust collector with low emission concentration. It has the following beneficial effects:

[0017] (1) The present invention effectively expands the range of movement and heat radiation of the heating component through the arrangement of an anti-adhesion device, through the coordination of an electric rotating rod, a sliding plate, a heating component, an arc-shaped guide plate, a fixed plate, a friction wheel, a cross bar, an elastic telescopic plate, an arc-shaped plate and a rejection plate, and forms a relatively sealed space when the arc-shaped guide plate contacts the V-shaped plate, and covers and guides the dust-laden gas, thereby prompting the dust-laden gas to move toward the direction of movement of the heating component, thereby accelerating the drying rate of the gas, and preventing the dust from adhering to the filter bag component due to humidity and becoming difficult to remove, thereby aggravating the erosion of the filter bag component by the dust; and by means of the elastic telescopic plate that continuously changes its movement direction, the heat flow and the dust-laden gas are subjected to rotational disturbance, and the arc surface of the arc-shaped plate effectively improves the smoothness of gas flow, and the rejection plate reduces the amount of dust adhering to the surface of the elastic telescopic plate, further improving the dryness of the dust, thereby facilitating the separation of gas and solid.

[0018] (2) The present invention sets up an anti-missing device, and cooperates with a sliding plate, an L-shaped plate, a support rod, a guide plate, a semicircular baffle, a hollow arc block, an L-shaped straight plate and an arc plate. With the help of the reciprocating swing of the guide plate, the dust-laden gas entering from the left side of the device body is guided, so as to prevent the larger particles of dust in the dust-laden gas from falling directly, thereby making it difficult to collect and discharge them in a centralized manner inside the discharge assembly, and to avoid the reduction of the centralized dust treatment effect of the device body; at the same time, the interception range of the guide plate is effectively expanded by relying on the L-shaped straight plate and the semicircular baffle, which further facilitates the particle dust to fall into the discharge assembly on the original basis, and prevents a small amount of dust from being left on the front side of the device body, which may easily lead to the leakage of missed dust and be inhaled by the staff during equipment maintenance.

[0019] (3) The present invention adopts the setting of the anti-pollution device, and cooperates with the arc panel, cam, screw rod, sliding ring, L-shaped rod, square frame, diverter plate, fixed rod, hollow purification roller, convex plate, convex ball rod and perforated ring. The square frame and diverter plate are used to conduct secondary drainage of the dust-containing gas contacted by the guide plate, thereby preventing dust from adhering to the surface of the guide plate and continuously eroding its outer wall. At the same time, the diverter plate is used to effectively scatter the dust accumulated on the surface of the guide plate due to moisture during the continuous swinging process, so as to facilitate the drying process by wind and heat flow, thereby preventing the agglomerated dust from being difficult to dry and remaining on the surface of the internal parts of the device body; and the perforated ring is used to continuously disturb the activated carbon particles inside the hollow purification roller, so that the activated carbon can continue to remain loose and active inside the hollow purification roller, thereby ensuring that the purified gas discharged through the pores on its own outer wall during the rotation of the hollow purification roller is sufficient. At the same time, with the help of the reciprocating swing of the guide plate and the guidance of the arc-shaped guide plate, the purified gas is used to absorb harmful substances in the dust-containing gas, thereby preventing the gas from being directly discharged to pollute the environment.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figures 1-9 One embodiment of the present invention is: an air box pulse bag dust collector with low emission concentration, including a support assembly 1, a device body 2 is provided on the top of the support assembly 1, an input pipe is provided on the left side of the device body 2, a discharge assembly 21 is provided at the bottom of the device body 2, a fan exhaust assembly 22 is provided on the right side of the device body 2, a pulse valve assembly 23 is provided on the left side of the top of the device body 2, and the pulse valve assembly 23 passes through the interior of the device body 2, a filter plate frame 3 is fixedly installed inside the device body 2, a filter bag assembly 31 is fixedly installed inside the filter plate frame 3, and a V-shaped plate 32 is provided on the left side of the bottom of the filter plate frame 3;

[0032] An anti-adhesion device 4 is provided on the left side of the device body 2, an anti-missing device 5 is provided on the periphery of the anti-adhesion device 4, and an anti-pollution device 6 is provided inside the anti-missing device 5;

[0033] The anti-adhesion device 4 includes an electric rotating rod 41, the bottom of the electric rotating rod 41 is rotatably installed on the left side of the bottom inner wall of the device body 2, a reciprocating spiral groove is opened on the upper part of the outside of the electric rotating rod 41, and a sliding plate 42 is movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod 41, and the left side of the sliding plate 42 is slidably installed on the left side of the inner wall of the device body 2, the bottom of the sliding plate 42 is symmetrically and fixedly installed with two heating components 43, the right side of the sliding plate 42 is hinged with an arc guide plate 44 through a torsion spring, and the top of the sliding plate 42 is symmetrically and fixedly installed with two fixed plates 45, a friction wheel 46 is rotatably installed on the side of the fixed plate 45 away from the axis of the sliding plate 42, and a cross bar 47 is fixedly installed on the side of the friction wheel 46 away from the fixed plate 45, and a number of elastic retractable plates 48 are equidistantly and fixedly installed on the outer wall of the cross bar 47, an arc plate 49 is hinged at the edge of the outer wall of the fixed end of the elastic retractable plate 48, and a rejection plate 410 is slidably installed on the fixed end of the elastic retractable plate 48.

[0034] The inclined surface of the V-shaped plate 32 is located on the motion track of the arc guide plate 44, the outer wall of the friction wheel 46 contacts the left side of the inner wall of the device body 2, the arc surface of the telescopic end of the elastic telescopic plate 48 contacts the left side of the inner wall of the device body 2, and the outer wall of the rejection plate 410 is hinged to the end of the arc plate 49 close to the cross bar 47. Through the above cooperation, the activity range and heat radiation range of the heating component 43 are effectively expanded, and the arc guide plate 44 forms a relatively sealed space when in contact with the V-shaped plate 32, and the dust-laden gas is enveloped and guided, thereby prompting the dust-laden gas to move in the direction of the heating component 43. The elastic plate 48 is moved closer to the filter bag assembly 31, thereby accelerating the drying rate of the gas and preventing the dust from adhering to the filter bag assembly 31 due to humidity and becoming difficult to remove, thereby aggravating the erosion of the filter bag assembly 31 by the dust. Through the above cooperation, the heat flow and the dust-laden gas are subjected to rotational disturbance by means of the elastic expansion plate 48 that continuously changes the direction of movement, and the arc surface of the arc plate 49 effectively improves the smoothness of gas circulation, and the rejection plate 410 reduces the amount of dust adhering to the surface of the elastic expansion plate 48, further improving the drying of the dust and facilitating the separation of gas and solid.

[0035] During use, dust-laden gas is transported to the interior of the device body 2 through the input pipe, and a wind turbine is provided at the bottom of the device body 2 to cause the dust-laden gas to surge upward inside the device body 2. Large particles of dust fall into the discharge assembly 21 under the action of gravity, and fine dust is intercepted by the filter bag assembly 31 and the filter plate frame 3 during the upward surge. Dust-free gas is discharged from the interior of the device body 2 through the fan exhaust assembly 22. When the pressure difference inside the device body 2 reaches a critical value, the pulse valve assembly 23 is started and air is blown to the filter bag assembly 31 to cause it to expand, and the dust attached to the surface or inside of the filter bag assembly 31 is blown off and falls into the discharge assembly 21. When the equipment is running, the electric rotating rod 41 is turned on in advance, and the electric rotating rod 41 moves along When the bottom of the inner wall of the device body 2 rotates, the reciprocating spiral groove on the outer wall of the sliding plate 42 limits the built-in block of the sliding plate, and when the electric rotating rod 41 rotates, the sliding plate 42 is enabled to slide upward along the left side of the inner wall of the device body 2 and reset, and the sliding plate 42 drives the heating component 43 to move synchronously. At the same time, the sliding plate 42 drives the arc guide plate 44 to move synchronously. During the upward movement of the arc guide plate 44, its top arc surface contacts the inclined surface of the V-shaped plate 32 and generates a resistance force. The hinge shaft of the arc guide plate 44 starts to rotate due to the resistance force and drives the arc guide plate 44 to flip toward the left side of the inner wall of the device body 2. Through the above cooperation, the activity range and heat radiation range of the heating component 43 are effectively expanded, and the arc guide plate 44 and When the V-shaped plates 32 are in contact, a relatively sealed space is formed, and the dust-laden gas is enveloped and guided, thereby forcing the dust-laden gas to move toward the direction of the heating component 43, thereby accelerating the drying rate of the gas, and preventing the dust from adhering to the filter bag component 31 due to humidity and becoming difficult to remove, thereby exacerbating the erosion of the filter bag component 31 by the dust; when the sliding plate 42 moves upward and resets, it drives the fixed plate 45 to move synchronously, and the fixed plate 45 drives the friction wheel 46 to rub synchronously along the left side of the inner wall of the device body 2, and the friction wheel 46 begins to rotate along the outer wall of the fixed plate 45 by friction and drives the cross bar 47 to rotate, and when the cross bar 47 drives the elastic telescopic plate 48 to revolve, the arc surface of the telescopic end of the elastic telescopic plate 48 disengages The contact limit with the left side of the inner wall of the device body 2, the telescopic end of the elastic telescopic plate 48 pulls the arc plate 49 to move away from the cross bar 47 under the elastic force of the spring, and the arc plate 49 drives the rejection plate 410 to slide synchronously along the fixed end of the elastic telescopic plate 48. When the arc surface of the telescopic end of the elastic telescopic plate 48 contacts the inner wall of the device body 2 again, it is reset by the resistance force, and this process is repeated. Through the above cooperation, the heat flow and dust-containing gas are rotationally disturbed by the elastic telescopic plate 48 that continuously changes its movement direction, and the arc surface of the arc plate 49 effectively improves the smoothness of gas circulation, and the rejection plate 410 reduces the amount of dust attached to the surface of the elastic telescopic plate 48, further improving the dryness of the dust and facilitating the separation of gas and solid.

[0036] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-missing device 5;

[0037] The anti-missing device 5 includes an L-shaped plate 51, a support rod 52 and a guide plate 53. The top of the L-shaped plate 51 is fixedly installed at the bottom edge of the sliding plate 42, and both ends of the support rod 52 are fixedly installed inside the L-shaped plate 51. The bottom of the guide plate 53 is hinged to the bottom of the inner wall of the device body 2 through a torsion spring. The inside of the guide plate 53 passes through and is hinged to the outer wall of the support rod 52. Through the above coordination, the reciprocating swing of the guide plate 53 is used to guide the dust-laden gas entering from the left side of the inside of the device body 2, thereby preventing larger particles of dust in the dust-laden gas from falling directly, making it difficult to collect and discharge them in a centralized manner inside the discharge component 21, thereby avoiding a reduction in the centralized dust treatment effect of the device body 2.

[0038] The anti-missing device 5 also includes a semicircular baffle 54, a hollow arc block 55, an L-shaped straight plate 56 and an arc panel 57. The bottom of the semicircular baffle 54 is slidably installed on the bottom of the inner wall of the device body 2, the back of the hollow arc block 55 is fixedly installed on the front of the outer wall of the semicircular baffle 54, the back of the left end of the L-shaped straight plate 56 is fixedly installed on the front of the L-shaped plate 51, and the front of the arc panel 57 is fixedly installed on the front of the inner wall of the L-shaped straight plate 56.

[0039] A spring is provided between the bottom of the semicircular baffle 54 and the device body 2, and the arc surface of the hollow arc block 55 is located on the movement trajectory of the arc panel 57. Through the above cooperation, the L-shaped straight plate 56 and the semicircular baffle 54 effectively expand the interception range of the guide plate 53, and on the original basis, it further facilitates the particle dust to fall into the discharge component 21, and at the same time prevents a small amount of dust from remaining on the front side of the device body 2, which may easily lead to missed dust overflow and inhalation by staff during equipment maintenance.

[0040] When in use, the sliding plate 42 moves upward reciprocatingly and drives the L-shaped plate 51 to move synchronously when it is reset. The L-shaped plate 51 drives the support rod 52 to move synchronously. When the support rod 52 moves upward, it is limited by the hinge shaft inside the guide plate 53, which causes the hinge end between the bottom of the guide plate 53 and the device body 2 to generate a rotational force. At this time, the guide plate 53 flips toward the center of the device body 2 with the hinge shaft as the axis. When the support rod 52 is reset by the L-shaped plate 51, it causes the guide plate 53 to reset synchronously. Through the above cooperation, the reciprocating swing of the guide plate 53 is used to guide the dust-laden gas entering from the left side of the device body 2, so as to prevent larger particles of dust in the dust-laden gas from falling directly, making it difficult to collect and discharge them in the discharge assembly 21, thereby avoiding the device body 2 from having a centralized treatment effect on the dust. Lower; when the L-shaped plate 51 moves upward, it drives the L-shaped straight plate 56 to move synchronously, and the L-shaped straight plate 56 drives the arc panel 57 to move synchronously. When the arc panel 57 moves upward, its own arc surface will contact and resist the arc surface of the hollow arc block 55 to generate a resistance thrust. At this time, the hollow arc block 55 drives the semicircular baffle 54 to slide along the bottom of the inner wall of the device body 2 toward its back. When the arc panel 57 passes over the hollow arc block 55, the semicircular baffle 54 is reset by the spring, and so on. Through the above cooperation, the L-shaped straight plate 56 and the semicircular baffle 54 effectively expand the interception range of the guide plate 53, which further facilitates the particle dust to fall into the discharge component 21 on the original basis, and at the same time prevents a small amount of dust from remaining on the front side of the device body 2, which may easily lead to missed dust overflow and inhalation by the staff during equipment maintenance.

[0041] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-pollution device 6;

[0042] The anti-pollution device 6 includes a cam 61, a screw rod 62, a sliding ring 63, an L-shaped rod 64, a square frame 65 and a plurality of diverter plates 66. The bottom of the cam 61 is rotatably mounted on the bottom of the inner wall of the device body 2, the bottom of the screw rod 62 is fixedly mounted on the top of the cam 61, the sliding ring 63 passes through and is threadedly connected to the outer wall of the screw rod 62, the bottom of the right end of the L-shaped rod 64 is fixedly mounted on the top of the arc panel 57, the left side of the top of the L-shaped rod 64 is fixedly mounted on the right side of the outer wall of the sliding ring 63, the bottom of the square frame 65 is slidably mounted on the outer wall of the guide plate 53 by a spring, the front of the square frame 65 is in contact with the outer wall of the cam 61, and the square frame A groove is provided at the bottom of 65, and the bottoms of several diverter plates 66 are hinged to the outer wall of the guide plate 53 through torsion springs. The tops of the diverter plates 66 are in contact with the inner walls of the grooves of the square frame 65. Through the above cooperation, the square frame 65 and the diverter plates 66 are used to conduct secondary drainage of the dust-laden gas in contact with the guide plate 53, preventing dust from adhering to the surface of the guide plate 53 and continuously eroding its outer wall. At the same time, the diverter plates 66 are continuously swinging to effectively scatter the dust accumulated on the surface of the guide plate 53 due to moisture, facilitating drying by wind and heat flow, and preventing agglomerated dust from being difficult to dry and remaining on the surface of the internal components of the device body 2.

[0043] The anti-pollution device 6 also includes a fixed rod 67, a hollow cleaning roller 68, a bump plate 69, a convex ball rod 610 and an open hole ring 611. Both ends of the fixed rod 67 are fixedly installed inside the square frame 65. The inner wall of the hollow cleaning roller 68 passes through and is rotatably installed on the outer wall of the fixed rod 67. The inside of the bump plate 69 passes through and is fixedly installed at one end of the bottom of the fixed rod 67. The convex ball rod 610 is arranged inside the hollow cleaning roller 68, and the inside of the open hole ring 611 is slidably installed inside the hollow cleaning roller 68 through a spring.

[0044] The outer wall of the hollow purification roller 68 contacts the outer wall of the guide plate 53, and activated carbon particles are arranged inside the hollow purification roller 68. The arc surface of the raised part of the convex block plate 69 is located on the movement trajectory of the convex ball rod 610. The open hole ring 611 passes through and is fixedly installed on the outer wall of the convex ball rod 610. Through the above cooperation, the open hole ring 611 continuously disturbs the activated carbon particles inside the hollow purification roller 68, so that the activated carbon can continue to remain loose and active inside the hollow purification roller 68, ensuring that the hollow purification roller 68 discharges sufficient purified gas through the pores on its own outer wall during the rotational movement. At the same time, with the help of the reciprocating swing of the guide plate 53 and the guidance of the arc-shaped guide plate 44, the purified gas is convenient for absorbing harmful substances in the dust-laden gas, preventing the gas from being directly discharged to pollute the environment.

[0045] When in use, the arc panel 57 moves upward, driving the L-shaped rod 64 to move synchronously. The L-shaped rod 64 pulls the sliding ring 63 to slide upward along the outer wall of the screw rod 62. When the sliding ring 63 slides, it drives the screw rod 62 connected by the thread to generate a rotating force. At this time, the screw rod 62 drives the cam 61 to start rotating along the bottom of the inner wall of the device body 2. When the cam 61 rotates, it breaks away from the limiting resistance of the square frame 65. The square frame 65 slides along the guide plate 53 toward the front of the device body 2 by the elastic force of the spring. When the cam 61 rotates one circle, it again resists the square frame 65 to reset, and the spring forces the square frame 65 to always be close to the outer wall of the cam 61. The square frame 65 contacts the diverter plate 66 through its bottom groove during the movement, and the diverter plate 66 causes its own hinge shaft to start rotating through the resistance force. At this time, the diverter plate 66 moves in an arc trajectory with the hinge shaft as the axis, and then the diverter plate 66 is reset by the torsion spring. Through the above cooperation, the square frame 65 and the diverter plate 66 are used to conduct secondary dredging of the dust-containing gas contacted by the guide plate 53, preventing dust from adhering to the surface of the guide plate 53 and continuously eroding its outer wall. At the same time, the diverter plate 66 is effectively scattered during the continuous swinging process to scatter the dust accumulated on the surface of the guide plate 53 due to moisture, which is convenient for wind and heat flow to perform drying treatment, avoiding The agglomerated dust is difficult to dry and thus remains on the surface of the internal parts of the device body 2; during the sliding process of the square frame 65, the fixed rod 67 is driven to move synchronously, and the fixed rod 67 drives the hollow cleaning roller 68 to slide and rub synchronously along the outer wall of the guide plate 53. The hollow cleaning roller 68 begins to rotate along the outer wall of the fixed rod 67 by friction, and the hollow cleaning roller 68 drives the perforated ring 611 to rotate. During the process of the perforated ring 611 driving the convex ball rod 610 to rotate, the arc surface of the convex ball rod 610 and the convex part of the convex plate 69 conflict with each other, and the fixed rod 67 limits the convex plate 69 to prompt the convex ball rod 610 to drive the perforated ring 611 to the hollow cleaning roller. The roller 68 moves in the internal direction, and then the perforated ring 611 is reset by the spring force and drives the convex ball rod 610 to reset, and this is repeated repeatedly. Through the above cooperation, the perforated ring 611 continuously disturbs the activated carbon particles inside the hollow purification roller 68, so that the activated carbon inside the hollow purification roller 68 can continue to remain loose and active, ensuring that the hollow purification roller 68 discharges sufficient purified gas through the pores on its own outer wall during the rotational movement. At the same time, with the help of the reciprocating swing of the guide plate 53 and the guidance of the arc-shaped guide plate 44, the purified gas can absorb harmful substances in the dust-laden gas to prevent the gas from being directly discharged to pollute the environment.
