Description

Technical Field

[0001] The invention belongs to the technical field of belt conveyors, and in particular relates to a debris recovery belt conveyor. Background Art

[0002] A belt conveyor is a device that transports materials, primarily solid materials. The main structure of a belt conveyor consists of a frame, a belt drum mounted on the frame, a transmission belt that drives the drum, and a drive mechanism.

[0003] When conveying materials, especially materials containing dust and debris, belt conveyors easily generate a large amount of dust when the materials are unloaded onto the conveyor belt due to their light texture. After the dust is generated, it will escape into the workshop, which not only seriously affects the health of the operators, but also seriously affects the normal operation of the workshop equipment.

[0004] Therefore, in order to solve the problem of dust escape, dust is prevented by installing a dust cover on the belt conveyor in the prior art. For example, the Chinese patent application number is: CN202420654606.6, which discloses a sealed belt conveyor. Specifically, its structure includes a support frame, and a dust frame is fixedly installed on the upper surface of the support frame. A closed space is formed by the arrangement of the outer shell, the frame and the scraper frame, so that the material will not be scattered during the conveying process, thereby preventing the generation of dust. At the same time, the arrangement of the outer shell collects the dust generated by the material in the dust cover to prevent it from spreading everywhere. The two ends of the outer shell are closed by the arrangement of the dust curtain to prevent dust from being discharged from the two ends of the outer shell. The worm and the worm gear are rotated by turning the rotating handle, and the dust curtain is wound or released by the winding drum driven by the worm gear. The height of the closed ends of the outer shell is adjusted according to the amount of conveyed material, so that dust can be prevented without affecting the conveying of the material.

[0005] The technical solution disclosed in the above patent solves the problem of dust pollution in the working environment in the prior art.

[0006] However, in the actual working process, it was found that although the belt conveyor was equipped with a dust cover, it could not be absolutely sealed, and dust could easily escape from the sides and inlets and outlets of the conveyor. Especially when the amount of dust was large, a large amount of dust was suspended in the air. Even if it was treated by exhaust dust removal, a large amount of dust still escaped.

[0007] The primary cause of these technical deficiencies is that for highly pulverized materials, especially lightweight ones, dust is dispersed significantly during the feeding process. Consequently, this dispersed dust, due to its light weight, has difficulty settling on the conveyor belt and onto the conveyed material. Consequently, dust covers and their associated exhaust and dust removal mechanisms have failed to fundamentally address this issue.

[0008] Furthermore, for large quantities of dust, even though the dust can be filtered out by the filtration devices on the dust extraction and removal structure for a short period of time, the filter element of the physical filtration structure will soon reach saturation after filtering dust under high load, making it unable to filter dust and significantly reducing the dust extraction and removal effect. Frequent replacement of filter elements is obviously not enough to meet production needs.

[0009] The reason is that during the production process in the workshop, belt conveyors often transport materials for a long time throughout the day. Therefore, if the dust problem cannot be solved fundamentally, the disadvantages of using belt conveyors will be significant. Summary of the Invention

[0010] Based on the above background, an object of the present invention is to provide a debris recovery belt conveyor.

[0011] To achieve the above objectives, the present invention adopts the following technical solutions:

[0012] A debris recovery belt conveyor comprises a belt conveyor body, the belt conveyor body comprising a frame, a transmission belt for transmitting materials being mounted on the frame, and a dust cover mounted on the top of the frame; a feeding structure is mounted on one side of the top of the dust cover, and a dust extraction structure is mounted on the other side of the top of the dust cover; the dust cover is characterized in that a dust suppression mechanism is assembled and connected to the inside of the dust cover, and during the transmission process of the belt conveyor, the dust is pressed down and settled on the transmission belt by the dust suppression mechanism;

[0014] The dust suppression mechanism also includes a push-adjustment mechanism for pushing the folding dust suppression unit to guide the dust; after the push-adjustment mechanism pushes the elastic dust suppression plate from both sides of the hanging rail for elastic compression, the angle of the folding dust suppression unit to guide the dust increases, and the dust sedimentation amplitude increases.

[0015] Preferably, both ends of the frame are rotatably connected to a driving belt drum and a driven belt drum respectively;

[0016] The transmission belt is driven between the driving belt drum and the driven belt drum;

[0017] It also includes a driving structure for driving the active belt drum, the driving structure includes a driving pulley installed on the active belt drum, and a transmission motor, and a driven pulley connected to the active pulley is installed on the output shaft of the transmission motor.

[0018] Preferably, a plurality of mounting brackets are fixedly mounted on both sides of the top of the frame, and the bottom of the dust cover is fixedly mounted on the mounting brackets.

[0019] Preferably, the longitudinal cross-section of the folded dust suppressing unit is V-shaped;

[0020] The V-shaped opening of the folded dust suppressing unit is arranged upward;

[0021] Length adjustment openings are respectively provided on both sides of the foldable dust pressing unit, and a pair of spaced hanging rails are slidably installed between the elastic dust pressing plates, and the hanging rails pass through the length adjustment openings;

[0022] The two ends of the hanging rail are respectively suspended and installed at the top position in the dust cover through suspension screws.

[0023] Preferably, the pushing and adjusting mechanism comprises a pair of pushing and adjusting trolley structures respectively installed at both ends of the hanging rail;

[0024] The pushing and adjusting trolley structure comprises an upper assembly connected with a plurality of pushing wheels that push against the folding dust pressing unit.

[0025] Preferably, the push-and-adjust trolley structure includes a shell provided on both sides;

[0026] A pair of driven push wheels and a driving push wheel are rotatably connected in the housing;

[0027] The hanging rail passes through the housing, and the driven push wheel and the active push wheel are clamped on the side walls on both sides of the hanging rail;

[0028] The driven push wheel and the active push wheel are provided with a slot, and the hanging rail is limited in the slot;

[0029] A motor for driving the active push wheel to rotate is installed on the top of the shell.

[0030] Preferably, a connecting bracket is integrally formed between the shells, and a plurality of pushing wheel arms are installed on the side of the connecting bracket facing the elastic dust suppressing plate, and the pushing wheel is rotatably connected to the pushing wheel arm.

[0031] Preferably, the dust extraction structure includes a filter housing connected to and mounted on the dust cover, and the bottom of the filter housing is connected to the dust cover via a lower spring tube;

[0032] A filter element for filtering dust is installed in the filter housing;

[0033] The top of the filter housing is connected to a dust extraction pipe, which is connected to an external exhaust pipe through an upper spring tube;

[0034] The dust extraction structure further includes a dust shaking structure; the dust attached to the filter element is shaken off by the shaking operation of the dust shaking structure;

[0035] The dust shaking structure includes a plurality of spring members elastically mounted on the filter housing;

[0036] The spring member includes a slide rail rod, and the filter housing is fixedly connected to a boss which is slidably connected to the slide rail rod;

[0037] The bottom of the slide rail rod is fixedly connected to the spring base fixedly mounted on the dust cover, and the top of the slide rail rod is fixedly connected to the spring top seat; the slide rail rod is sleeved with a lower spring, and the two ends of the lower spring are respectively fixedly connected between the spring base and the bottom of the convex seat; the slide rail rod is sleeved with an upper spring, and the two ends of the upper spring are respectively fixedly connected between the spring top seat and the top of the convex seat;

[0038] The dust shaking structure also includes several locking pressure cylinders. The downward pressure of the locking pressure cylinder keeps the lower filter housing in a depressed position. When the piston rod of the locking pressure cylinder is disengaged, the filter housing shakes up and down with the assistance of the upper spring and the lower spring, shaking off a large amount of dust attached to the filter element.

[0039] Preferably, a shaking pressure bracket is installed on the filter housing, a cylinder pressure seat is installed on the shaking pressure bracket, and the piston rod of the locking pressure cylinder contacts and presses on the shaking pressure bracket;

[0040] The cylinder barrel of the locking cylinder is fixedly mounted with a cylinder barrel bracket.

[0041] Preferably, side dust covers are respectively installed on both sides of the frame;

[0042] The feeding structure includes a feeding hopper connected to the top of the dust cover.

[0043] The present invention has the following beneficial effects:

[0044] 1. The present invention cleverly uses a dust suppression structure to fundamentally solve the technical problem of dust escape.

[0045] Specifically, the present invention arranges a dust suppression mechanism in the dust cover to suppress the dust, thereby causing the dust to recombine with the material on the conveyor belt to form a non-dispersible state, thereby essentially solving the problem of dust leakage.

[0046] 2. In the improved dust suppression mechanism, by adjusting the shape and posture of the dust suppression mechanism and changing the dust suppression effect range, the efficiency of exhaust dust removal and the efficiency of dust pressure sedimentation are coordinated. That is, when the amount of dust is very large, the dust pressure sedimentation is increased mainly, and exhaust dust removal is secondary (at this time, the large amount of dust requires reducing the material feeding speed). On the contrary, when the dust amount is moderate, in order to quickly exhaust dust to increase the material transmission speed (speed up the material feeding speed), the shape and posture of the dust suppression mechanism is adjusted again to reduce the wind resistance to increase the airflow and dust passing speed.

[0047] 3. The dust suppressing mechanism includes an elastic dust suppressing plate suspended above the transmission belt. The elastic dust suppressing plate is made of elastic plastic material and includes a number of integrally formed folding dust suppressing units (V-shaped with the opening facing upward). The V-shaped folding dust suppressing units are integrally formed, and the connecting parts of the adjacent V-shaped folding dust suppressing units are integrally formed with elastic plastic of V-shaped structure. In this way, the elastic dust suppressing plate is in a "VVVVVVV" posture in a normal posture (non-pressurized state). Once the two ends of the elastic dust suppressing plate are pressed toward the center, each folding dust suppressing unit is pressed (the connecting part of the V-shaped structure is made of elastic plastic and is therefore squeezed and deformed). At this time, the V-shaped angle of the V-shaped structure will decrease, and along with the deformation, the sides of the two sides of the folding dust suppressing unit of the V-shaped structure gradually move closer.

[0048] When the dust is guided from both sides of the folded dust suppressing unit, the guiding direction of the airflow (mixed dust) is gradually switched from an inclined posture to a vertical posture.

[0049] However, due to the change in the diversion direction of the airflow (mixed dust), the amplitude of the downward pressure and sedimentation of the dust changes, which is reflected in the fact that the sides of the two sides of the V-shaped folded dust suppression unit gradually move closer together, and the verticality of the diversion gradually increases. At this time, the verticality of the dust toward the transmission belt increases, and then the amplitude of the downward pressure and sedimentation increases (the opening of the V-shaped structure gradually decreases).

[0050] However, since the sides of the V-shaped folded dust suppressing unit gradually approach each other, the distance between the folded dust suppressing unit and the transmission belt decreases, and the wind resistance increases. When the wind resistance increases, the downward pressure and sedimentation amplitude of the dust is further increased.

[0051] As the pressure at both ends of the elastic dust suppressing plate disappears or decreases, the elastic dust suppressing plate gradually restores its shape with the cooperation of the elastic restoring force of the folded dust suppressing unit, which is reflected in the gradual increase of the V-shaped opening of the V-shaped structure; at this time, the downward pressure and sedimentation effect of the airflow (dust) is reduced, but the wind resistance is reduced, and dust can be extracted and removed faster.

[0052] When the elastic dust suppressing plate 52 is in the "VVVVVVV" posture, the dust and airflow are reduced in speed under the diversion effect, further providing conditions for the dust to land on the transmission belt.

[0053] 4. A push-and-adjust trolley structure is designed and improved to achieve the above process by autonomously pushing the elastic dust-pressing plate in a relatively sealed cover.

[0054] 5. By improving a device that can shake the dust during the dust extraction process, the dust coated on the filter element can be shaken off, which solves the defect of frequent manual removal of the filter. At the same time, it can also achieve the effect of shaking off the dust even if it is shaken off. For example, if the dust is extracted and removed once every 10 hours, the dust can be shaken off before it is coated and compacted. What is even better is that the dust can be shaken off during the dust extraction process.

[0055] 6. Under normal circumstances, the piston rod of the locking cylinder extends and presses down on the cylinder seat. This downward pressure forces the filter housing down, causing the upper spring to be stretched and the lower spring to be compressed. When the filter housing needs to be shaken to remove dust trapped on and entrained in the filter element, the locking cylinder resets and the piston rod disengages from the cylinder seat. Once the downward pressure is removed, the elastic restoring forces of the upper and lower springs cause the filter housing (and the filter element within) to vibrate up and down. The continuous deformation of the lower and upper springs causes the filter housing to move up and down on the slide rail in a variable speed, vibrating until the lower and upper springs reset. The locking cylinder piston rod then presses down again and releases. After repeated cycles, a significant amount of dust is shaken off the filter element in the filter housing. Some of the removed dust is carried away by the suctioned airflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] Example 1

[0075] like Figure 1-13 As shown, a debris recovery belt conveyor includes a belt conveyor body 1. The structure of the belt conveyor body 1 is similar to that of conventional belt conveyors disclosed in the prior art. The main structure includes a frame 11, with a driving belt drum 13 and a driven belt drum rotatably connected at each end of the frame 11. A transmission belt is transmitted between the driving belt drum 13 and the driven belt drum. The frame 11 also includes a drive structure 12 for driving the driving belt drum. The drive structure includes a driving pulley mounted on the driving belt drum and a transmission motor. A driven pulley connected to the driving pulley is mounted on the output shaft of the transmission motor. Furthermore, the frame 11 is equipped with rollers 14 for supporting the transmission belt.

[0076] During operation, materials such as highly crushed debris are fed from the rear end of the belt conveyor body 1 and discharged from the front end.

[0077] In order to reduce dust emission during material transfer during operation, a dust cover 2 is installed on the top of the frame 11 in the existing manner. Specifically, similar to the installation method of the existing dust cover 2, a plurality of mounting brackets are fixedly installed on both sides of the top of the frame 11, and the bottom of the dust cover 2 is fixedly mounted on the mounting brackets.

[0078] The dust cover 2's barrier function reduces dust emission. However, in actual operation, when the amount of dust is large, such as due to factors such as excessive feeding speed, excessive dust dryness, excessive pulverization, or light material, dust emission during material transportation can be severe. Therefore, the dust cover 2 with a traditional structure cannot fully suppress dust emission.

[0079] Therefore, the present invention arranges a dust suppression mechanism 5 in the dust cover 2 to suppress the dust, prompting the dust to recombine with the material on the conveyor belt to form a non-dissipated state, thereby essentially solving the problem of dust leakage.

[0080] In the improved dust suppressing mechanism 5, by adjusting the shape and posture of the dust suppressing mechanism 5 and changing the dust suppressing effect amplitude thereof, the efficiency of exhaust dust removal and the efficiency of dust pressure sedimentation are coordinated. That is, when the amount of dust is very large, the dust pressure sedimentation is mainly increased, and exhaust dust removal is secondary (at this time, the large amount of dust requires reducing the material feeding speed). On the contrary, when the amount of dust is moderate, in order to quickly exhaust dust to increase the material transmission speed (speed up the material feeding speed), the shape and posture of the dust suppressing mechanism 5 is adjusted again to reduce the wind resistance to increase the airflow and dust passing speed.

[0081] Specifically, the dust suppressing mechanism 5 includes an elastic dust suppressing plate 52 suspended above the transmission belt by a hanging rail 51. The material of the elastic dust suppressing plate 52 is an elastic plastic material, which includes a number of folding dust suppressing units (V-shaped, with the opening facing upward) that are integrally formed. The folding dust suppressing units of the V-shaped structure are integrally formed, and the elastic plastic of the V-shaped structure is integrally formed between the connecting parts of the folding dust suppressing units of adjacent V-shaped structures. In this way, the elastic dust suppressing plate 52 is in a "VVVVVVV" posture in a normal posture (non-pressurized state), and once the two ends of the elastic dust suppressing plate 52 are pressed toward the center, at this time, each folding dust suppressing unit is pressed (the connecting part of the V-shaped structure is elastic plastic, so it is squeezed and deformed). At this time, the V-shaped angle of the V-shaped structure will be reduced, and along with the deformation, the sides of the two sides of the folding dust suppressing unit of the V-shaped structure gradually move closer.

[0082] This is reflected in the fact that when the dust is guided down from both sides of the folded dust suppressing unit, the direction of the airflow (mixed dust) gradually switches from an inclined posture to a vertical posture.

[0083] However, due to the change in the diversion direction of the airflow (mixed dust), the amplitude of the downward pressure and sedimentation of the dust changes, which is reflected in the fact that the sides of the two sides of the V-shaped folded dust suppression unit gradually move closer (that is, the opening amplitude of the V-shaped structure gradually decreases), and the verticality of the diversion gradually increases. At this time, the verticality of the dust toward the transmission belt increases, and the amplitude of the downward pressure and sedimentation increases.

[0084] However, since the sides of the V-shaped folded dust suppressing unit gradually move closer (the opening amplitude of the V-shaped structure gradually decreases), the distance between the folded dust suppressing unit and the transmission belt decreases, and the wind resistance increases. When the wind resistance increases, the downward pressure and sedimentation amplitude of the dust is further increased.

[0085] As the pressure at both ends of the elastic dust suppressing plate 52 disappears or decreases, the elastic dust suppressing plate 52 gradually returns to its original shape with the cooperation of the elastic restoring force of the folded dust suppressing unit, which is reflected in the gradual enlargement of the V-shaped opening of the V-shaped structure; at this time, the downward pressure and sedimentation effect of the airflow (dust) is reduced, but the wind resistance is reduced, and dust can be extracted and removed faster.

[0086] Moreover, when the elastic dust suppressing plate 52 is in the "VVVVVVV" posture, the dust and airflow are reduced in speed under the diversion effect, further providing conditions for the dust to deposit on the transmission belt.

[0087] Example 2

[0088] like Figure 1-13 As shown, in this embodiment, based on the structure of embodiment 1, the dust suppressing mechanism 5 further includes a pushing and adjusting mechanism for pushing the angle of the folding dust suppressing unit to guide the dust; after the pushing and adjusting mechanism pushes the elastic dust suppressing plate 52 from both sides of the hanging rail 51 for elastic compression, the angle of the folding dust suppressing unit to guide the dust increases, and the dust settling amplitude increases.

[0089] Specifically, length adjustment openings 521 are respectively provided on both sides of the foldable dust suppressing unit, and a pair of spaced hanging rails 51 are slidably installed between the elastic dust suppressing plates 52. Specifically, according to the installation method of the hanging rails 51 disclosed in the prior art, the two ends of the above-mentioned hanging rails 51 are respectively suspended and installed at the top position inside the dust cover 2 through the suspension screws 53.

[0090] Each hanging rail 51 passes through the length adjustment opening 521 (i.e., passes through between the folding dust suppressing units). The length adjustment opening 521 provides a deformation gap for the deformation of the folding dust suppressing unit, that is, when the elastic dust suppressing plate 52 is deformed, the hanging rail 51 is relatively adjusted in the length adjustment opening 521.

[0091] The pushing and adjusting mechanism includes a pair of pushing and adjusting trolley structures 54 respectively installed at the two ends of the hanging rail 51.

[0092] That is, the front and rear pusher structures 54 push the elastic dust suppressor plates 52 toward each other from the front end, causing the aforementioned process of increasing dust downward pressure and sedimentation. Conversely, when the pusher structures 54 move away from each other, the elastic restoring force of the elastic dust suppressor plates 52 cooperates, producing the aforementioned effect of increasing dust extraction (increasing material feed rate).

[0093] Specifically, the push-and-turn trolley structure 54 includes a housing 541 (the transverse cross-section of the housing 541 is circular) disposed on either side. A pair of driven push wheels 546 and a driving push wheel 547 are rotatably connected within the housing 541. The hanging rail 51 extends through the housing 541 (slidingly connected to the housing 541), and the driven push wheels 546 and the driving push wheels 547 are clamped to the side walls of the hanging rail 51.

[0094] At the same time, in order to improve the clamping stability of the driven push wheel 546 and the active push wheel 547, a slot A is opened on the contour of the driven push wheel 546 and the active push wheel 547, and the hanging rail 51 is limited in the slot A; a motor 542 is installed on the top of the shell 541 to drive the active push wheel 547 to rotate.

[0095] During operation, when driven by the motor 542, the shells 541 at the left and right ends move autonomously on the hanging rail 51. In this process, autonomous movement is achieved by the friction power of the driven push wheel 546 and the active push wheel 547. And because the hanging rail 51 is slidably connected to the shell 541, derailment can be effectively avoided. When the push-and-turn trolley structure 54 moves autonomously, the elastic dust suppressing plates 52 at both ends are pushed toward the center, causing the elastic dust suppressing plates 52 to deform, thereby exerting the above-described effect of increasing downward pressure and reducing dust.

[0096] Example 3

[0097] like Figure 1-13 As shown, based on the structure of Example 2, in order to push the elastic dust suppressing plate 52 to move closer and deform, the above-mentioned pushing and adjusting trolley structure 54 includes a plurality of pushing wheels 545 connected to the upper assembly and pushed against the folding dust suppressing unit.

[0098] Specifically, a connecting bracket 543 is integrally formed between the shells 541 , and a plurality of pushing wheel arms 544 are installed on the side of the connecting bracket 543 facing the elastic dust suppressing plate 52 , and the pushing wheel 545 is rotatably connected to the pushing wheel arm 544 .

[0099] During the pushing process, the pushing wheel 545 first contacts the end of the elastic dust suppressing plate 52. During the contact process, as the pushing and adjusting trolley structure 54 continues to move, the elastic dust suppressing plate 52 is continuously compressed and deformed, and the pushing wheel 545 always maintains a tight contact position. The rolling friction of the pushing wheel 545 reduces the deformation resistance of the elastic dust suppressing plate 52 under the pushing action.

[0100] Furthermore, in this way, the two ends are pushed against the elastic dust suppressing plate 52, which can ensure that the elastic dust suppressing plate 52 can flexibly complete the posture deformation process.

[0101] Example 4

[0102] like Figure 1-13 As shown, based on the structure of Example 3, in order to further prevent dust from escaping from the front and rear sides of the frame 11, side dust covers 6 are respectively installed on the front and rear sides of the frame 11 according to the existing method.

[0103] The side dust cover 6 further prevents dust from escaping from the side during operation.

[0104] Example 5

[0105] like Figure 1-13As shown, this embodiment is based on the structure of Example 3 and is the same as the existing feeding method. A feeding structure is installed on the top rear side of the above-mentioned dust cover 2. The feeding structure is specifically a feed hopper 4 connected to the dust cover 2. The discharge end of the feed hopper 4 passes through the dust cover 2 and is close to the transmission belt.

[0106] At the same time, a dust extraction structure is installed on the top right side of the dust cover 2; similar to the existing exhaust dust removal method, the above-mentioned dust extraction structure includes a filter housing 3 connected to and installed on the dust cover 2, and the bottom of the filter housing 3 is connected to the dust cover 2 through a lower spring tube 32; a filter element 31 for filtering dust is installed in the filter housing 3.

[0107] The filter element 31 installed in the filter housing 3 is a conventional dust filtering structure disclosed in the prior art. During operation, the air outlet of the filter housing 3 is connected to an external exhaust duct. In the prior art, the external exhaust duct is installed with a fan to achieve exhaust and dust removal.

[0108] Example 6

[0109] like Figure 1-13 As shown, this embodiment is based on the structure of embodiment 5. In the existing dust filter structure, the filter element 31 is fixedly installed in the filter housing 3 in a detachable manner.

[0110] However, in actual operation, as the time of exhaust dust removal increases, especially when the amount of dust is large, the filter element 31 is quickly wrapped by the attached dust, thereby reducing the filtering effect. In the prior art, the filter housing 3 is disassembled and the filter element 31 is removed. The dust is shaken off by shaking and the filter element 31 is then reinstalled for use.

[0111] However, the disadvantages of this method are that frequent operation is too cumbersome, and if the dust is not shaken in time, once the dust is tightly wrapped and the thickness of the wrap is large, it is difficult to remove the dust. A more serious drawback is that once the filter element 31 is removed during the workshop production process, dust extraction cannot be continued and the dust quickly escapes.

[0112] Therefore, by improving a method that can shake the dust during the dust extraction process, the dust coated on the filter element 31 can be shaken off, which solves the defect of frequent manual disassembly. At the same time, it can also achieve even shaking off of the dust. For example, if the dust extraction is performed once every 10 hours, the dust can be shaken off before it is coated and compacted. What is even better is that the dust can be shaken off during the dust extraction process.

[0113] Specifically, the improvement is as follows: a dust extraction pipe 33 is connected to the top of the filter housing 3, and the dust extraction pipe 33 is connected to the external exhaust pipe through the upper spring tube 34. The flexible structure of the connection method is the basic condition for achieving the shaking formation.

[0114] At the same time, the dust extraction structure also includes a dust shaking structure; the dust attached to the filter element 31 is shaken off by the shaking work of the dust shaking structure.

[0115] Example 7

[0116] like Figure 1-13 As shown, this embodiment discloses the specific structure of the dust shaking structure based on the structure of Example 6.

[0117] Specifically, the dust shaking structure includes a pair of spring members elastically mounted on the filter housing 3 (symmetrically mounted).

[0118] The spring member includes a slide rail rod, and a corresponding protrusion slidably connected to the slide rail rod is fixedly connected to the filter housing 3. The bottom of the slide rail rod is fixedly connected to a spring base fixedly mounted on the dust cover 2, and the top of the slide rail rod is fixedly connected to a spring top seat. A lower spring 36 is sleeved on the slide rail rod, and the two ends of the lower spring 36 are respectively fixedly connected between the spring base and the bottom of the protrusion. An upper spring 37 is sleeved on the slide rail rod, and the two ends of the upper spring 37 are respectively fixedly connected between the spring top seat and the top of the protrusion.

[0119] At the same time, the dust shaking structure also includes two locking cylinders 35. The downward pressure of the locking cylinder 35 keeps the lower filter housing 3 in a depressed position. When the piston rod of the locking cylinder 35 is disengaged, the filter housing 3 shakes up and down with the assistance of the upper spring 37 and the lower spring 36, shaking off a large amount of dust attached to the filter element 31.

[0120] Specifically, a pressure-shaking bracket 38 is installed on the filter housing 3 . Specifically, a mounting seat is installed on the upper end of the left and right side walls of the filter housing 3 , and the pressure-shaking bracket 38 is fastened to the mounting seat by means of bolts 382 .

[0121] At the same time, a cylinder pressure seat 381 is installed on the shaking pressure bracket 38, and the piston rod of the locking pressure cylinder 35 touches and presses on the shaking pressure bracket 38. The cylinder is fixed in the following way: the cylinder barrel of the locking pressure cylinder 35 is fixedly installed with a cylinder barrel bracket 351. The cylinder barrel bracket 351 is fixedly installed on the top of the dust cover 2.

[0122] Under normal circumstances, the piston rod of the locking cylinder 35 is extended and pressed down on the cylinder pressure seat 381. Under the downward pressure, the filter housing 3 is in a depressed position. At this time, the upper spring 37 is in a stretched state, and the lower spring 36 is in a compressed state.

[0123] When the filter housing 3 needs to be shaken to remove dust adsorbed on or trapped by the filter element 31 inside the filter housing 3, the locking cylinder 35 is reset, and the piston rod is released from the cylinder pressure seat 381. After the downward pressure is lost, the filter housing 3 (and the internal filter element 31) are elastically shaken up and down under the elastic restoring force of the upper spring 37 and the lower spring 36.

[0124] As a result, the filter housing 3 moves up and down the slide rails, shifting at varying speeds due to the continuous deformation of the lower and upper springs 36 and 37. This motion appears to be oscillating until the lower and upper springs 36 and 37 return to their original positions. The piston rod of the locking cylinder 35 then presses down and releases again. After several cycles of this, a significant amount of dust is shaken off the filter element 31 within the filter housing 3. This dust is partially carried away by the suction airflow.

[0125] During this process, the spring hose is deformed in coordination with the dust shaking process due to its flexible connecting structure.

[0126] In this way, the filter element 31 in the filter housing 3 is processed in an efficient and automatic manner, and the filter element 31 in the filter housing 3 is always kept in a relatively clean position. In this way, the technical defect of frequently disassembling the filter to remove the filter element 31 and process the dust in the prior art is very cleverly solved.

[0127] Furthermore, the above method realizes exhausting dust and shaking off dust at the same time, thus avoiding interference with the normal operation of the equipment.

[0128] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
