Description

Technical Field

[0001] This invention relates to the field of bag pulse dust collector technology, specifically to a bag pulse dust collector for cat litter production. Background Technology

[0002] Dust sources in the cat litter production process mainly originate from multiple stages, including raw material transportation, screening, mixing, and packaging. Particularly during the processing of natural bentonite cat litter, silica cat litter, and plant-based cat litter, fine particles are easily stirred up, forming dust suspended in the air. This dust not only affects the cleanliness of the production environment but also poses a threat to human health. Long-term exposure to dust can lead to respiratory diseases such as pneumoconiosis and asthma. Furthermore, dust accumulation can damage equipment, especially in high-temperature areas of machinery, where dust may cause electrical component malfunctions and even increase the risk of fire. Therefore, efficient collection and treatment of this dust has become an urgent need for modern cat litter manufacturers.

[0003] A utility model patent (publication number: CN221713820U) discloses a bag pulse dust collector for cat litter production, comprising a dust collection box, a pulse assembly, an exhaust fan, and multiple dust collection bags. The outlet of the pulse assembly is positioned above the multiple dust collection bags for dust removal from the surface of the dust collection bags. The dust collection box is equipped with a replacement mechanism, which includes two front and rear first slide rails. The two first slide rails are fixedly connected to the left and right sides of the inner wall of the dust collection box, respectively. A bag mounting plate is slidably connected between the two first slide rails. A baffle is fixedly connected to the back of the bag mounting plate. Multiple dust collection bags are installed inside the baffle. A locking assembly is provided behind the baffle to press and lock it. A through groove matching the size of the baffle is opened on the back of the dust collection box. A rotating rod is rotatably connected between the front and back of the inner wall of the dust collection box, and the rotating rod extends to the back of the dust collection box. Two gears are fixedly connected to the surface of the rotating rod.

[0004] The above-mentioned application and existing technology have the following technical problems in actual use:

[0005] 1. The aforementioned application and existing baghouse dust collectors all use regular cylindrical bag shapes. However, in actual production workshops, various types of cat litter are typically processed. Different types of cat litter have different particle sizes. For larger cat litter particles, the filtration efficiency of the bag will be affected because larger particles are more likely to accumulate on the bag surface, leading to a decrease in filtration effectiveness. Therefore, the current single bag shape cannot fully meet actual production needs.

[0006] 2. Cat litter granules have a certain degree of hardness, which causes significant wear and tear on the filter bag material, especially for regular cylindrical filter bags. As the usage time increases, the filter bags are easily worn or damaged, thereby reducing the filtration effect and system efficiency. Summary of the Invention

[0007] The purpose of this invention is to solve the above problems by providing a bag pulse dust collector for cat litter production.

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0009] A bag pulse dust collector for cat litter production includes a dust collector housing, an air inlet pipe is provided on the lower left side of the dust collector housing, a pulse blowing system is provided on the top of the dust collector housing, an exhaust pipe is provided on the upper right side of the dust collector housing, and a fan is provided at the outlet of the exhaust pipe.

[0010] The dust collector housing contains several frame assemblies. A filter bag is fitted onto the outside of each frame assembly. Each frame assembly includes a fixed inner rod fixedly installed inside the dust collector housing. Multiple sets of guide frames are arranged on the outside of the fixed inner rod. Each set of guide frames consists of two annular frames. Several swing frames are annularly hinged to corresponding surfaces of adjacent guide frames. The swing frames can swing up and down. A telescopic frame is slidably connected to the end of the swing frame away from the guide frame. Corresponding telescopic frames on adjacent guide frames are hinged together. Connectors are provided on both sides of the swing frames and telescopic frames. Support springs are provided between the connectors on adjacent annular swing frames. The inclination direction of both ends of the support springs is adjustable. The filter bag consists of alternating thick and thin sections. The thick sections are fixedly connected to the swing frames and support springs, while the thin sections are fixedly connected to the guide frames.

[0011] Furthermore, a fixed cross brace is fixedly installed inside the dust collector shell. Several mounting holes are opened through the inside of the fixed cross brace, and the fixed inner rod passes through the mounting holes and is welded to the mounting holes.

[0012] Furthermore, the fixed inner rod has a hollow interior design, and a lifting rod is slidably connected inside the fixed inner rod. Several lifting windows are opened on the outer side of the fixed inner rod, and the lifting windows are located between adjacent guide frames. A lifting collar is sleeved on the outer side of the lifting rod, and the lifting collar passes through the lifting window and is fixedly connected to the lifting rod. Several transmission rods are hinged on the outer side of the lifting collar, and the other end of the transmission rod is hinged to the inner side of the swing frame.

[0013] Furthermore, a lifting cylinder is fixedly installed on the inner wall of the dust collector shell, a lifting frame is fixedly installed on the top of the telescopic end of the lifting cylinder, and the lifting rod is fixedly installed at the bottom of the lifting frame.

[0014] Furthermore, the connector has a Y-shaped guide groove inside, and a switching swing plate is rotatably installed at the intersection of the Y-shaped guide groove. The switching swing plate can swing, and both ends of the support spring are provided with sliding plates, which are slidably connected in the Y-shaped guide groove.

[0015] Furthermore, the Y-shaped guide groove consists of two bifurcated portions and a straight portion. The straight portion is away from the swing frame, and its length is greater than the length of the slide plate and its height is greater than the thickness of the portion of the slide plate located in the Y-shaped guide groove.

[0016] Furthermore, a top plate is slidably connected inside the straight section, and a top spring is provided between the top plate and the inner wall of the straight section. A transmission cavity is opened inside the connecting member. A worm gear is fixedly installed at the rotation center of the switching swing plate. The worm gear is located in the transmission cavity. A transmission shaft is rotatably installed inside the transmission cavity. The transmission shaft consists of a worm part and a transmission part. The worm part meshes with the worm wheel. Two sets of spiral guide grooves and two sets of straight grooves are opened on the outer side of the transmission part. The two sets of spiral guide grooves rotate in opposite directions. The straight grooves connect the beginning and end of the two sets of spiral guide grooves. The end of the straight groove is higher than the beginning of the corresponding spiral guide groove, and the beginning of the straight groove is lower than the end of the corresponding spiral guide groove. A transmission collar is provided on the outer side of the top plate. A sliding hole is opened on the inner wall of the transmission collar. A transmission pin is slidably connected inside the sliding hole. A retaining spring is provided between the transmission pin and the inner wall of the sliding hole. An anti-deviation head is provided on the outer side of the transmission pin. The transmission collar is sleeved on the transmission part. The anti-deviation head can slide along the spiral guide groove and the straight groove.

[0017] Furthermore, an external fixing plate is provided on the outer side of the bag, and the external fixing plate is correspondingly provided with the swing frame.

[0018] Furthermore, the external fixing plate is fixedly installed on the swing frame by bolts.

[0019] Furthermore, the external fixing plate is magnetically attached to the swing frame.

[0020] The beneficial effects of this invention are as follows:

[0021] When filtering normal granular cat litter, the swing frame of this invention swings outward and unfolds, and the cloth bag forms a double-cone disc shape. Due to its more symmetrical and streamlined shape, the airflow on the surface of the cloth bag is more uniform, and the filter surface is inclined, which can prevent the accumulation of cat litter particles, reduce the wear of cat litter on the cloth bag, and improve its service life.

[0022] When filtering large-particle cat litter, this invention features an outward-protruding support spring and an inward-swinging frame, causing the cloth bag to form an outward-protruding drumstick shape. The filter surface is an outward-protruding arc surface, which can more effectively reduce the impact of large particles on the cloth bag, reduce wear, and improve service life.

[0023] When filtering fine cat litter, this invention features a concave support spring and an inward swinging frame, causing the cloth bag to form a concave drumstick shape. The filter surface is a concave arc surface, which reduces impact while concentrating and collecting the filtered fine cat litter, allowing it to fall in a concentrated manner, reducing splashing, and facilitating subsequent cleaning.

[0024] In summary, this invention, through the design of the skeleton component, can switch the bag state according to the type of cat litter to adapt to the filtration of cat litter with different particle sizes. When filtering cat litter with different particle sizes, the curved or inclined surface is used to reduce impact and wear, while also achieving efficient filtration for different types of cat litter.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] Example 1, as Figures 1-12 As shown, a bag pulse dust collector for cat litter production includes a dust collector housing 1, an air inlet pipe 2 is provided on the lower left side of the dust collector housing 1, a pulse blowing system 3 is provided on the top of the dust collector housing 1, an exhaust pipe 4 is provided on the upper right side of the dust collector housing 1, and a fan 5 is provided at the outlet of the exhaust pipe 4.

[0040] The dust collector housing 1 has several frame components inside, and a filter bag 8 is sleeved on the outside of the frame components. The frame components include a fixed inner rod 6 fixedly installed inside the dust collector housing 1. Multiple sets of flow guide frames 61 are arranged on the outside of the fixed inner rod 6. Each set of flow guide frames 61 consists of two annular frames. Several swing frames 63 are annularly hinged on the corresponding surfaces of adjacent flow guide frames 61. The swing frames 63 can swing up and down. A telescopic frame 64 is slidably connected to the end of the swing frame 63 away from the flow guide frame 61. The corresponding telescopic frames 64 on adjacent flow guide frames 61 are hinged together. Connectors 9 are provided on both sides of the swing frames 63 and the telescopic frames 64. A support spring 10 is provided between the connectors 9 on the adjacent annular swing frames 63. The tilt direction of the two ends of the support spring 10 is adjustable. The filter bag 8 is composed of alternating thick and thin parts. The thick parts are fixedly connected to the swing frames 63 and the support spring 10, and the thin parts are fixedly connected to the flow guide frames 61.

[0041] Production waste gas enters the dust collector through the air inlet pipe 2, where cat litter particles are filtered down by the filter bag 8. The clean gas enters the inside of the filter bag 8, then flows upward through the guide frame 61, and finally is discharged through the exhaust pipe 4 and the fan 5. After running for a period of time, the pulse blowing system 3 blows air from the top of the filter bag 8 into the filter bag 8, blowing off the filter particles on its surface.

[0042] When filtering normal granular cat litter, the upper swing frame 63 is controlled to swing upwards. The upper swing frame 63 drives the telescopic frame 64 to swing outwards. At the same time, the telescopic frame 64 extends, and the upper telescopic frame 64 drives the lower swing frame 63 to swing outwards synchronously through the lower telescopic frame 64. The swing frame 63 expands the thicker part of the bag 8 outwards. As the swing frame 63 swings outwards, the distance between adjacent upper swing frames 63 increases, and the support spring 10 gradually straightens under its own elastic force. Finally, the thicker part of the bag 8 forms a double-cone disc shape, as shown in the attached figure. Figure 4 As shown, due to its more symmetrical and streamlined shape, the airflow on the surface of the bag 8 is more uniform, and the filter surface is inclined, so the impact direction of the cat litter forms a certain angle with the outer surface of the bag 8, which can reduce the impact force, prevent the accumulation of cat litter particles, reduce the wear of cat litter on the bag 8, and improve its service life.

[0043] When filtering large-particle cat litter, the litter tends to clump and has a greater impact force. Therefore, the impact reduction effect of a simple inclined plane is limited. Furthermore, the clumped litter easily accumulates on the upper surface of the double-cone disc-shaped bag 8. Therefore, the ends of the support spring strip 10 are bent inwards, and the swing frame 63 is controlled to swing back. The distance between adjacent swing frames 63 decreases, causing the swing frame 63 to compress the support spring strip 10, making it bulge outwards. At this point, the coarse part of the bag 8 forms an outwardly convex drumstick shape, and the filter surface is an outwardly convex arc surface, as shown in the attached diagram. Figure 11 As shown, it can more effectively reduce the impact of large particles on the filter bag 8, reduce wear, and prevent the accumulation of clumped particles on the surface of the filter bag 8, resulting in good filtration effect.

[0044] When filtering small cat litter particles, these particles tend to stick to the outer surface of the cloth bag 8. Both of these conditions make it difficult to clean the litter from the cloth bag 8. Therefore, the two ends of the support spring strip 10 are bent outwards, and the swing frame 63 is controlled to swing back. The distance between adjacent swing frames 63 decreases, causing the swing frame 63 to press the support spring strip 10, making it concave inwards. At this time, the coarse part of the cloth bag 8 forms a concave drumstick shape, and the filter surface is a concave arc surface, as shown in the attached diagram. Figure 12 As shown, it can reduce impact and wear, while also concentrating the fine cat litter filtered from the bag 8 inwards. The concentrated falling of the fine cat litter reduces splashing and improves subsequent cleaning efficiency.

[0045] It should be noted that when the deformation occurs in the thicker part and the bag 8 is in a double-cone disc shape, the thicker part is in an open state. Therefore, when the swing frame 63 moves inward, wrinkles will generally appear in the middle of the bag 8. However, this invention, through the setting of the convex and concave elastic bars, ensures that the bag 8 will not produce wrinkles in any of the three forms, thus ensuring the stability of the filter surface and preventing significant changes in the filter surface, thereby ensuring the filtration efficiency in different forms.

[0046] Therefore, the design of this invention can fully meet the needs of cat litter production.

[0047] Example 2, based on the above examples, further includes a fixed cross brace 11 fixedly installed inside the dust collector housing 1. The fixed cross brace 11 has several mounting holes through it. The fixed inner rod 6 passes through the mounting holes and is welded to the mounting holes for secure fixing.

[0048] Example 3, based on the above examples, further includes a hollow design inside the fixed inner rod 6, with a lifting rod 7 slidably connected inside the fixed inner rod 6, and several lifting windows 62 opened on the outer side of the fixed inner rod 6. The lifting windows 62 are located between adjacent guide frames 61, and a lifting collar 71 is sleeved on the outer side of the lifting rod 7. The lifting collar 71 passes through the lifting window 62 and is fixedly connected to the lifting rod 7. Several transmission rods 72 are hinged on the outer side of the lifting collar 71, and the other end of the transmission rods 72 is hinged to the inner side of the swing frame 63.

[0049] A lifting cylinder 12 is fixedly installed on the inner wall of the dust collector housing 1. A lifting frame 13 is fixedly installed on the top of the telescopic end of the lifting cylinder 12, and a lifting rod 7 is fixedly installed at the bottom of the lifting frame 13.

[0050] By controlling the operation of the lifting cylinder 12, the lifting cylinder 12 drives the lifting frame 13 to rise and fall, the lifting frame 13 drives the lifting rod 7 to rise and fall, the lifting rod 7 drives the lifting collar 71 to rise and fall along the lifting window 62, and the lifting collar 71 drives the upper swing frame 63 to swing through the transmission rod 72. The control is simple and can control all the cloth bags 8 to deform at the same time.

[0051] Furthermore, both the lifting cylinder 12 and the lifting frame 13 are located in the exhaust cavity of the upper half of the dust collector housing 1, and are not affected by filtration.

[0052] Example 4, based on the above examples, further includes a Y-shaped guide groove 91 inside the connector 9, a switching swing plate 94 rotatably installed at the intersection of the Y-shaped guide groove 91, the switching swing plate 94 can swing, and slide plates 101 are provided at both ends of the support spring bar 10, the slide plates 101 are slidably connected in the Y-shaped guide groove 91.

[0053] The Y-shaped guide groove 91 consists of two bifurcated parts and a straight part. The straight part is away from the swing frame 63. The length of the straight part is greater than the length of the slide plate 101, and the height is greater than the thickness of the part of the slide plate 101 located in the Y-shaped guide groove 91. Through this design, the slide plate 101 with a certain length can smoothly slide from the bifurcated part to the straight part.

[0054] A top plate 92 is slidably connected inside the straight section. A top spring 93 is provided between the top plate 92 and the inner wall of the straight section. A transmission cavity is opened inside the connecting piece 9. A worm gear 95 is fixedly installed at the rotation center of the switching swing plate 94. The worm gear 95 is located in the transmission cavity. A transmission shaft 96 is rotatably installed inside the transmission cavity. The transmission shaft 96 consists of a worm part 961 and a transmission part 962. The worm part 961 meshes with the worm gear 95. Two sets of spiral guide grooves 963 and two sets of straight grooves 964 are opened on the outer side of the transmission part 962. The two sets of spiral guide grooves 963 rotate in opposite directions, and the straight grooves 964 cause the two sets of spiral guide grooves 963 to rotate in opposite directions. The ends of the three sections are connected. The end of the straight groove 964 is higher than the beginning of the corresponding spiral guide groove 963, and the beginning of the straight groove 964 is lower than the end of the corresponding spiral guide groove 963. A transmission collar 921 is provided on the outer side of the top plate 92. A sliding hole is opened on the inner wall of the transmission collar 921. A transmission locking pin 922 is slidably connected inside the sliding hole. A retaining spring 923 is provided between the transmission locking pin 922 and the inner wall of the sliding hole. An anti-deviation head 924 is provided on the outer side of the transmission locking pin 922. The transmission collar 921 is sleeved on the transmission part 962. The anti-deviation head 924 can slide along the spiral guide groove 963 and the straight groove 964.

[0055] When the thicker part of the bag 8 is in a double-conical disc shape, the swing frame 63 swings to its outermost position, the thicker part of the bag 8 is fully expanded, the support spring 10 is taut, the slide plate 101 slides to the middle of the straight section, and the slide plate 101 pushes the top plate 92 to slide. The top plate 92 compresses the top spring 93, and the top plate 92 slides relative to the transmission part 962. Under the action of the transmission pin 922 and the positive spiral guide groove 963, the transmission part 962 drives the transmission shaft 96 to rotate. The transmission shaft 96 drives the worm wheel 95 to rotate through the worm part 961. The worm wheel 95 drives the switching swing plate 94 to swing downward. At this time, the lower forked part is blocked. At this time, the transmission pin 922 slides to the tail end of the positive spiral guide groove 963, and the retaining spring 923 pushes the transmission pin 922 into the head end of the corresponding straight groove 964. When the swing frame 63 swings back, the swing frame 63 drives the connecting piece 9 to move towards the support spring bar 10. The slide plate 101 moves away from the top plate 92. Under the guidance of the switching swing plate 94, the slide plate 101 enters the upper bifurcation. Since the slide plate 101 has a certain length, the two slide plates 101 at both ends make the two ends of the support spring bar 10 tilt upward along the upper bifurcation. At this time, when the swing frame 63 closes, the support spring bar 10 is concave inward. Simultaneously, the top spring 93 pushes the top plate 92 to reset, and the top plate 92 drives the transmission pin 922 to slide along the straight groove 964 to the first end of the counter-rotating spiral guide groove 963. Therefore, when the swing frame 63 is controlled to swing outward again, the transmission pin 922 drives the transmission shaft 96 to reverse through the counter-rotating spiral guide groove 963. The transmission shaft 96 drives the worm wheel 95 to reverse through the worm part 961. The switching swing plate 94 swings upward, blocking the upper fork. The slide plate 101 enters the lower fork under the guidance of the switching swing plate 94. Since the slide plate 101 has a certain length, the two slide plates 101 cause the two ends of the support spring bar 10 to tilt downward along the lower fork. At this time, when the swing frame 63 is closed, the support spring bar 10 protrudes outward. At this time, the transmission pin 922 enters another set of straight grooves 964. When the top spring 93 pushes the top plate 92 to reset, it enters the first end of the forward spiral guide groove 963 through the straight groove 964.

[0056] Therefore, by controlling the number of swings of the swing frame 63 inward and outward, the outward or inward control of the support spring bar 10 can be achieved without a complex control structure. A simple guide structure can be used to switch between them, making the control simple.

[0057] It should be noted that when the top plate 92 slides linearly to reset, the transmission pin 922 also slides linearly along the linear groove 964. The pressing surfaces of the linear groove 964 and the transmission pin 922 are inclined, which ensures that the two sets of spiral guide grooves 963 are connected end to end. Simultaneously, the anti-deviation sway head 924, whose length is greater than the width of the spiral guide groove 963, prevents it from sliding into the opposite spiral guide groove 963 when it reaches the intersection, thus ensuring stable transmission.

[0058] Example 5, based on the above examples, further includes an outer fixing piece 81 provided on the outside of the cloth bag 8, and the outer fixing piece 81 is correspondingly provided with the swing frame 63.

[0059] The external fixing plate 81 is fixedly installed on the swing frame 63 by bolts.

[0060] By setting the external fixing piece 81, the connection between the cloth bag 8 and the swing frame 63 can be covered to prevent excessive wear of the connection part from causing the cloth bag 8 to rupture and leak air. It can also fix the cloth bag 8 to the swing frame 63 more stably, making the cloth bag 8 more stable when deformed.

[0061] Example 6, based on the above examples, further includes an external fixing piece 81 that is magnetically attached to the swing frame 63. While the fixing effect is not as good as in Example 5, this example is more convenient to install and easier to disassemble and replace later.

[0062] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
