A blasting component 3 for blowing air is installed on the base, and the blasting component 3 is composed of a machine chamber 31, a motor 32, a fan blade 33 and a splicing pipe 34. A circular hole is opened on the front shell wall of the machine chamber 31 to serve as an air inlet. The motor 32 is fixedly connected to the back outer wall of the machine chamber 31 by bolts, and the fan blade 33 is located inside the machine chamber 31 and connected to the output end of the motor 32. Then, when the motor 32 is running, it drives the fan blade 33 to rotate, thereby realizing the blasting effect of the equipment. The outer ring bottom of the machine chamber 31 is set on the carrier 2, and the splicing pipe 34 is fixedly connected to the air inlet of the machine chamber 31 by bolts.

[0046] See also Figure 1 , Figure 3 , Figure 4 and Figure 5In the embodiment of the present invention, an exhaust gas treatment component 4 for treating exhaust gas is installed at the air inlet of the blast component 3. The exhaust gas treatment component 4 includes an air inlet switching mechanism 41, and a filter assembly 42 for filtering gas is symmetrically arranged inside the air inlet switching mechanism 41. The two filter assemblies 42 are arranged to correspond to different air inlet channels, so as to facilitate the switching and adjustment of the air inlet. A windshield mechanism 43 for blocking the port of the air inlet switching mechanism 41 is installed on the outside of the filter assembly 42. The opening and closing adjustment of the port of the air inlet switching mechanism 41 is achieved by switching and adjusting the windshield mechanism 43. A cleaning mechanism located on the air inlet switching mechanism 41 is provided on the side of each filter assembly 42, and the cleaning mechanism is used to wipe and clean the filter assembly 42. Wiping and cleaning the filter assembly 42 by the cleaning mechanism not only delays the time of its blockage, but also accelerates its cleaning efficiency. A rotating connector 46 is installed on the air inlet switching mechanism 41, and the rotating connector 46 is connected to the blast component 3 through an air guide pipe 47. Through the cooperation of the air guide tube 47 and the rotating connector 46 , the diverted portion of the gas to be discharged can be refluxed for reuse, thereby achieving reverse blowing of the filter component 42 and reducing the burden of manual cleaning of the filter component 42 .

[0047] See also Figure 1-Figure 3 and Figure 6 In the embodiment of the present invention, the air inlet switching mechanism 41 is composed of a housing 411, a gasket 412, a switching member 413, an arc-shaped base plate 414, a bidirectional arc-shaped slide 415, a cover assembly 416 and a collection cage 417. The housing 411 includes a sleeve fixedly connected to the splicing tube 34 by bolts, and an air duct for air intake is symmetrically arranged on the peripheral wall of the sleeve, and the inner cavity of the air duct is connected to the inner cavity of the sleeve. The two air ducts are two air inlets of the housing 411 in the air inlet switching mechanism 41, and the ends of the two air ducts can be connected by pipes through bolts.

[0048] The cleaning mechanism is composed of a wiping assembly 44 and a driving assembly 45. The wiping assembly 44 is located on the outside of the filter assembly 42, and the driving assembly 45 is located on the inside of the wiping assembly 44. The wiping assembly 44 and the driving assembly 45 are movably connected. The arrangement of the driving assembly 45 on the inside of the wiping assembly 44 ensures that, on the one hand, the external gas will first contact the filter assembly 42 after entering the air duct, thereby preventing the foreign matter mixed in the gas from directly contacting the filter assembly 42 and ensuring its service life. On the other hand, when the gas of the switching member 413 performs reverse cleaning on the filter assembly 42, it is ensured that the gas first contacts the driving assembly 45, so that it has a sufficiently strong power.

[0049] See also Figure 6-Figure 9In the embodiment of the present invention, the switching member 413 is rotatably connected to the inner cavity of the sleeve, and the gasket 412 is integrally arranged on the inner wall of the sleeve, and the gasket 412 is located at the front side of the switching member 413. The gasket 412 mainly plays a sealing role. The gasket 412 is arranged to ensure that the gas entering the sleeve will not be discharged from the front side of the sleeve, thereby ensuring the direction of gas flow. The switching member 413 is composed of an arc plate and a disc, wherein the disc is integrally arranged at the front end of the arc plate.

[0050] The front side of the gasket 412 is provided with an arc-shaped slideway located on the peripheral wall of the sleeve. The arc-shaped base plate 414 slideway is connected to the arc-shaped slideway, the bottom end of the arc-shaped base plate 414 is fixedly connected to the front outer wall of the switching member 413, and the bidirectional arc-shaped slide 415 is fixedly connected to the top outer wall of the arc-shaped base plate 414. When the switching member 413 is rotated and adjusted, the bidirectional arc-shaped slide 415 is synchronously driven to rotate through the arc-shaped base plate 414.

[0051] A plurality of air guide channels are provided on the switching member 413 along the circumferential direction, and the plurality of air guide channels are gathered into a dispersion chamber on the front shell wall of the switching member 413. A hole is provided on the front shell wall of the dispersion chamber, and an air intake pipe is installed in the hole, and one front end of the air intake pipe extends to the front outside of the sleeve. Each air guide channel is provided with a plurality of air holes located on the peripheral wall of the switching member 413. Through the cooperation of the air guide pipe 47 and the rotary connector 46, part of the refluxed gas enters the dispersion chamber with the help of the air intake pipe, and then enters each air guide channel, and finally is released through the air holes provided on each air guide channel.

[0052] When the switching member 413 is rotating and switching, during the rotation from 0 to 90 degrees, the air holes on the switching member 413 are transposed as it rotates, so that the air holes are misplaced in the air duct and correspond to the bottom inner wall of the sleeve. At this time, the backflow gas is blocked. After the switching member 413 is rotated and adjusted by 90 degrees, the original air duct is still in a blocked state, but the other air duct is not blocked. When the switching member 413 is rotating and adjusted from 90 to 180 degrees, the original air duct is opened, while the other air duct is blocked, and the backflow gas enters the other air duct.

[0053] A rectangular notch and a notch are provided on the bottom shell wall of each air duct, and a through slot is provided between the rectangular notch and the notch on the top shell wall of the air duct, and the through slot is used to load the filter assembly 42. The filter assembly 42 is loaded in the through slot by plug-in assembly and then fixed by screws. The notch is located on the inner side of the through slot and is used to assemble the drive assembly 45.

[0054] See also Figure 6-Figure 7 and Fig. 9In the embodiment of the present invention, the cover assembly 416 includes grooves opened on both sides of the top of the rectangular notch, and the outer groove is movably connected to the cover plate 4161 through a pin shaft. The groove arranged on the inner side is used to accommodate the cover plate 4161 when the cover plate 4161 is closed. The two ends of the pin shaft respectively penetrate the corresponding shell wall of the air duct, and the rear end of the pin shaft is installed with a transmission gear 4162. Above the transmission gear 4162, there is a special-shaped rack 4163 that meshes with the transmission gear 4162. The special-shaped rack 4163 is connected to the corresponding shell wall of the air duct by a slideway, thereby ensuring the stability of the assembly of the special-shaped rack 4163 and guiding and supporting its displacement adjustment. The front and rear sides of the cover plate 4161 are both sleeved with torsion springs located on the pin shaft. The setting of the torsion spring enables the cover plate 4161 to reset itself without the action of external force, thereby achieving the covering of the rectangular notch.

[0055] The collection cage 417 is installed on the bottom outer wall of the air duct by screws, and the collection cage 417 is located directly below the rectangular notch. The setting of the collection cage 417 collects the debris cleaned from the filter assembly 42 and the air duct. The collection cage 417 adopts a mesh cage design, and the gap of the mesh cage is smaller than the diameter of the debris to prevent the debris from passing through the gap and scattering to the outside, so that the debris can be collected and the reverse flow of gas can be discharged from the air duct.

[0056] An arc-shaped through slot is provided on the front shell wall of the sleeve, and a column is slidably connected in the arc-shaped through slot. The rear end of the column is fixedly connected to the front shell wall of the switching member 413, and an adjustment disk is installed at the front end of the column, and an adjustment handle is plugged into the adjustment disk. By setting the arc-shaped through slot, the rotation adjustment direction of the switching member 413 can be determined to avoid errors during adjustment.

[0057] The two ends of the arc channel are provided with limit holes on the front shell wall of the sleeve, and the limit holes are inserted and limited with the adjustment handle. The adjustment handle and the limit holes cooperate to ensure the limit locking of the switch member 413 after rotation adjustment.

[0058] See also Figure 3-Figure 6 In the embodiment of the present invention, the windshield mechanism 43 includes a windshield plate 431 movably connected to the corresponding air duct through a mounting shaft. Both ends of the mounting shaft respectively penetrate the corresponding shell wall of the air duct, and a driven gear 432 is installed on the top of the mounting shaft. A transmission rack 433 meshing with the driven gear 432 is provided on the front side of the driven gear 432, and the bottom of the transmission rack 433 is slidably connected to the top outer wall of the air duct, and an L-shaped plate 434 is installed on the front shell wall of the transmission rack 433 by screws.

[0059] A contact rod 435 is provided at the bottom of the L-shaped plate 434, and a support for auxiliary support is sleeved on the contact rod 435. The support is installed on the front outer wall of the air duct by screws, and a return spring located on the contact rod 435 is sleeved between the L-shaped plate 434 and the support.

[0060] The end of the contact rod 435 away from the L-shaped plate 434 is connected with a ball rolling, and the ball rolling contacts with the bidirectional arc slide 415. When the bidirectional arc slide 415 contacts the ball on the contact rod 435, it pushes the contact rod 435, so that the contact rod 435 moves on the support, and synchronously drives the transmission rack 433 to move through the L-shaped plate 434, compressing the reset spring. The transmission rack 433 and the driven gear 432 are meshed and transmitted, so that the rotation adjustment of the wind deflector 431 is realized through the installation shaft. Since a sealing gasket is provided on the side of the wind deflector 431, the effect of blocking the air duct is guaranteed when it blocks the air duct.

[0061] See also Figure 3 , Fig.10 , Fig.11 and Fig.12 In the embodiment of the present invention, the wiping assembly 44 includes a cleaning plate 441 located in the air duct, and the cleaning plate 441 is located between the filter assembly 42 and the windshield mechanism 43. The cleaning plate 441 adopts a grid structure, so that when it cleans the filter assembly 42, it can still ensure the ventilation and filtering effect of the filter assembly 42 on the gas.

[0062] The bottom of the cleaning plate 441 is symmetrically provided with guide rods 442, and the bottom ends of the two guide rods 442 pass through the bottom shell wall of the air duct and are connected to the integration plate 443. The two guide rods 442 are provided to ensure the stability of the cleaning plate 441 during movement, and the guide rods 442 and the integration plate 443 are fixed by bolts to facilitate the disassembly and assembly operation.

The housing 451 is mounted on the bottom outer wall of the air duct by screws, and the housing 451 is located directly below the notch.

[0064] The impeller 452 is movably connected to the inside of the housing 451 through the connecting shaft, and some blades of the impeller 452 pass through the notch to reach the inside of the air duct, so as to facilitate contact with the gas in the air duct. The two ends of the connecting shaft respectively penetrate the corresponding side walls of the housing 451. The friction wheel 453 is arranged at the rear end of the connecting shaft, and the peripheral wall of the friction wheel 453 is in friction contact with the special-shaped rack 4163.

[0065] The coupling body 454 is mounted on the front end of the connecting shaft, and the reciprocating screw 455 is arranged on the front end of the coupling body 454, and the reciprocating screw 455 is threadedly connected with an inner groove ring. The reciprocating screw 455 drives the movement of the inner groove ring when the coupling body 454 moves. One end of the push-pull rod 456 is fixedly connected to the outer peripheral wall of the inner groove ring by a screw, and the other end of the push-pull rod 456 is fixedly connected to the convex rod. Under the action of the push-pull rod 456, the inner groove ring moves linearly when the reciprocating screw 455 moves, thereby driving the push-pull rod 456 to move synchronously.

[0066] A sliding sleeve is slidably connected to the push-pull rod 456 , and the sliding sleeve is fixed to the supporting plate by bolts, so that the push-pull rod 456 is easy to assemble.

[0067] The rotating connector 46 is arranged on the air inlet pipe, and a diversion port is provided on the side wall of the cabin 31. The air guide pipe 47 is fixedly connected to the side outer wall of the cabin 31 by screws, and the air guide pipe 47 is located at the diversion port. The other end of the air guide pipe 47 is installed on the rotating connector 46. Part of the gas diverted from the diversion port of the cabin 31 enters the rotating connector 46 through the transportation of the air guide pipe 47, and then enters the air inlet pipe. The setting of the rotating connector 46 ensures the rotation action of the switching member 413.

[0068] The working principle of the present invention is: when the equipment is running, the motor 32 in the air blowing component 3 is started, so that the fan blades 33 rotate, thereby absorbing the air in the workshop, and then the absorbed air is discharged from the air outlet of the machine room 31. When the air blowing component 3 is running, the air in the workshop enters from any open port of the air inlet switching mechanism 41 in the exhaust gas treatment component 4, and then enters the air blowing component 3 after being processed by the filter component 42. At this time, the ports on both sides of the air inlet switching mechanism 41 are in a state of one closed and one open.

[0069] When the air in the workshop enters the interior of the housing 411 in the air inlet switching mechanism 41, it is first processed by the filter assembly 42, and then the flowing air passes through the corresponding air duct and enters the air blowing component 3 through the sleeve to blow the impeller 452 in the driving assembly 45 provided in the corresponding air duct, so that the connecting shaft loaded with the impeller 452 rotates. During the rotation process, the connecting shaft synchronously drives the friction wheel 453 and the coupling body 454 loaded thereon to move synchronously. The friction wheel 453 is in friction contact with the special-shaped rack 4163 in the corresponding cover assembly 416, and the coupling body 454 drives the reciprocating screw 455 connected thereto to rotate.

[0070] Since the special-shaped rack 4163 in the cover assembly 416 has reached the maximum mileage in the current movement direction, the cover plate 4161 in the cover assembly 416 is in a state of covering the rectangular gap. Therefore, the friction wheel 453 cannot drive the special-shaped rack 4163 to move during the rotation process. At this time, the friction wheel 453 is in an idling activity with the movement of the connecting shaft.

[0071] The reciprocating screw 455 causes the inner ring threaded thereon to move during the rotation process. Due to the sliding guide of the push-pull rod 456 on the corresponding wiping assembly 44, the inner ring performs reciprocating linear movement when the reciprocating screw 455 rotates, thereby driving the corresponding push-pull rod 456 to move. When the push-pull rod 456 moves linearly with the inner ring, it drives the corresponding protruding rod to reciprocate in the inclined groove of the vertical plate 444 in the corresponding wiping assembly 44. The movement of the protruding rod in the inclined groove of the vertical plate 444 causes the integration plate 443 to perform reciprocating lifting and lowering adjustment. The movement of the integration plate 443 drives the corresponding cleaning plate 441 to move through the guide rod 442, thereby cleaning the filter assembly 42 in the current air duct and delaying the time of its blockage.

[0072] When the processed gas is discharged from the air outlet of the cabin 31, part of the gas enters the air guide pipe 47 from the diversion port, and is transported to the air intake pipe by the air guide pipe 47 in combination with the rotating connector 46. The gas entering the air intake pipe enters the dispersion chamber on the switching member 413, and then is dispersed and output through each air guide channel. The gas entering each air guide channel is discharged from the air vents on the air guide channel, and the gas discharged from the air vents directly enters the closed air duct on the housing 411 in the air inlet switching mechanism 41.

[0073] At this time, the flow of gas reverses the impeller 452 in the driving assembly 45 provided in the air duct. The impeller 452 reverses and drives the connecting shaft to reversely move, and the connecting shaft makes the friction wheel 453 and the coupling body 454 mounted thereon move synchronously.

[0074] The friction wheel 453 here frictionally contacts with the special-shaped rack 4163 in the corresponding cover assembly 416 during the rotation process. Since the movement direction of the special-shaped rack 4163 here is in the opposite direction at this time, when the friction wheel 453 contacts the special-shaped rack 4163 here, it moves. The movement of the special-shaped rack 4163 here causes the transmission gear 4162 meshing with it to move, thereby driving the pin shaft to move, so that the corresponding cover plate 4161 opens to reveal the obstructed rectangular gap. When the special-shaped rack 4163 moves to the maximum mileage, it is difficult to move. At this time, the subsequent movement of the friction wheel 453 can only ensure that the special-shaped rack 4163 is always at the maximum mileage in this direction, and the torsion spring sleeved on the pin shaft does not drive the cover plate 4161 to reset, so that the rectangular gap here is in an open state in the current state.

[0075] The coupling body 454 here drives the reciprocating screw rod 455 to move, and then drives the corresponding push-pull rod 456 to perform synchronous reciprocating motion under the reciprocating linear motion of the inner ring, so that the cleaning plate 441 in the wiping component 44 can clean the filter component 42 here.

[0076] At this time, the gas exhausted from the vent hole directly blows the filter component 42 in the opposite direction, and combined with the cleaning action of the cleaning plate 441 in the wiping component 44, the debris blocked on the filter component 42 is self-cleaned. The cleaned debris enters the corresponding collection cage 417 through the rectangular gap under the action of gas and gravity for collection and treatment.

[0077] When it is necessary to switch and adjust the air inlet of the air inlet switching mechanism 41 in the exhaust gas treatment component 4, first pull out the adjustment handle to disengage it from the current limit hole, and then use the adjustment handle to rotate and adjust the switching member 413. At this time, the rotation direction of the switching member 413 must be consistent with the direction of the arc-shaped through groove on the front shell wall of the sleeve. When the switching member 413 is rotated and adjusted to the maximum mileage, the adjustment handle is inserted into the required limit hole to achieve the limit locking of the adjusted switching member 413.

[0078] During the process of rotation and switching, the switching member 413 drives the bidirectional arc slide 415 to move synchronously through the arc base plate 414. When the bidirectional arc slide 415 is adjusted, after the bidirectional arc slide 415 rotates away, the contact rod 435 in the current windshield mechanism 43 in contact with it is disengaged. Then the reset spring on the contact rod 435 performs a reset movement, and the corresponding transmission rack 433 is displaced through the corresponding L-shaped plate 434. The transmission rack 433 and the driven gear 432 are meshed and transmitted, so that the installation shaft drives the corresponding windshield plate 431 to rotate and adjust by 90 degrees, so as to achieve the current windshield plate 431 blocking the air duct at that location.

[0079] After the switching member 413 rotates 90 degrees, the air vent is misplaced, thereby reducing the gas in the air duct that was originally cleaned by the filter assembly 42, and the torsion spring in the cover assembly 416 performs a reset movement, thereby realizing the cover reset of the current cover plate 4161. At this time, the contact rod 435 in the windshield mechanism 43 provided on the air duct contacts the adjusted bidirectional arc slide 415. The corresponding reset spring is squeezed, and the corresponding transmission rack 433 is displaced through the L-shaped plate 434. The transmission rack 433 and the driven gear 432 are meshed and transmitted, so that the installation shaft drives the corresponding windshield plate 431 to rotate 90 degrees, thereby opening the current windshield plate 431 and realizing the opening of the blockage of the air duct.

[0080] When the switching member 413 completes the rotation adjustment of 180 degrees, the switching member 413 completes the rotation switching.

[0081] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
