Description

Technical Field

[0001] This utility model relates to the field of dust recovery technology, specifically to a dust recovery device for a cat litter production line. Background Technology

[0002] When cats dig in litter and bury their excrement, they inhale dust particles. Long-term inhalation of these particles is harmful to a cat's health. Therefore, modern cat litter production typically involves dust removal processes, and the removed dust can be recycled and reused as raw materials.

[0003] Currently, most mainstream dust collection equipment uses a negative pressure dust collection system, which connects the dust collection device to the filtration system through a dust collection pipe. During operation, the dust-laden airflow passes through the filter screen under negative pressure, and dust particles are intercepted and adsorbed on the surface of the filter screen. Subsequently, the mechanical vibration generated by the rapping mechanism causes the adsorbed dust to fall off, completing the collection.

[0004] However, this technology has significant drawbacks: existing rapping mechanisms mostly act directly on the dust filter screen. Under high-frequency, high-intensity vibration and impact, the filter screen fiber structure gradually becomes fatigued and damaged, resulting in problems such as holes and breaks. As the filter screen damage intensifies, it not only leads to an increase in dust escape rate and a significant decrease in recovery efficiency, but also requires frequent filter screen replacements, increasing equipment maintenance costs and operating energy consumption, severely restricting the long-term stable operation of the dust recovery system. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a dust recovery device for a cat litter production line, which solves the problem in the existing technology where the rapping mechanism directly acts on the dust filter, causing the dust filter to gradually break under long-term high-intensity impact, ultimately leading to a decrease in dust recovery efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a dust recovery device for a cat litter production line, comprising: a dust filter screen disposed inside a housing, the dust filter screen being fixed by a dust filter frame, the dust filter screen dividing the housing into a first chamber and a second chamber; a rapping mechanism disposed inside the second chamber; wherein the rapping mechanism includes a rapping block, the rapping block rotating within the second chamber and rapping the dust filter frame, the rapping block being limited by a tension spring.

[0007] Optionally, the dust filter screen is provided with a cover fixed to the dust filter frame, and the cover and the dust filter screen together form a closed second chamber that can block dust.

[0008] Optionally, a rotating shaft is rotatably provided in the second chamber, and a spiral auger is fixed to the rotating shaft by a frame. The vibrating block is rotatably mounted on the spiral auger, and one end of the tension spring is connected to the vibrating block, while the other end of the tension spring is connected to the spiral auger.

[0009] Optionally, the dust filter frame includes several fixed rings arranged in a uniform array, and the dust filter screen is fixed on the fixed rings.

[0010] Optionally, a plurality of first and second pillars are also fixed on the fixing ring, and the vibrating block rotates when it touches the first pillar and vibrates on the second pillar.

[0011] Optionally, a flexible layer is fitted onto the vibrating block, the first support column, and the second support column.

[0012] Optionally, the housing has a dust inlet pipe, a dust outlet pipe, and an air outlet pipe, wherein the dust inlet pipe and the dust outlet pipe are connected to the first chamber, and the air outlet pipe is connected to the second chamber.

[0013] Optionally, it also includes a cat litter production device having a dust collection hood connected to the dust inlet pipe.

[0014] Optionally, the air outlet pipe is equipped with an exhaust fan for ventilation, and the dust outlet pipe is equipped with a dust collection component for dust collection.

[0015] Optionally, the rotating shaft is driven to rotate by a motor, which is fixed to the housing.

[0016] The beneficial effects of this utility model are as follows: This invention utilizes a vibrating block to strike the dust filter frame, causing the frame to vibrate. This vibration, in turn, causes the dust collected on the filter screen to fall off and be collected. This design avoids damage to the filter mesh caused by the vibration mechanism directly acting on it, thus extending the lifespan of the filter screen.

[0017] Next, this utility model uses a spiral auger to connect the vibrating blocks, so that the vibrating blocks are evenly distributed on the spiral auger. During the rotation of the spiral auger, the vibrating blocks drive the dust filter frame to vibrate the upper and lower parts, thus avoiding the problem in the prior art where the vibrating mechanism only acts on a certain filter part, resulting in poor dust shaking effect in other parts.

[0018] In addition, this utility model utilizes the first and second pillars to connect several fixed rings, so that after the first and second pillars are subjected to the vibration of the vibration block, the vibration force is distributed to various parts of the dust filter frame, avoiding fatigue problems caused by excessive vibration stress concentration during long-term use.

[0019] Finally, the vibrating block of this invention is limited by a tension spring, which allows it to rotate when it contacts the first support column. At this time, the tension spring is stretched. When the vibrating block is separated from the first support column, it resets under the action of the tension spring and then strikes the second support column. This design allows the vibrating mechanism to vibrate the dust filter frame without an additional driving device, thus improving the stability of the vibrating. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As mentioned earlier, the shortcomings of existing dust recovery equipment are that their rapping mechanisms often act directly on the filter screen. Under high-frequency, high-intensity vibration and impact, the filter screen fiber structure gradually becomes fatigued and damaged, resulting in problems such as holes and breaks. As the filter screen damage intensifies, not only does it lead to an increase in dust escape rate and a significant decrease in recovery efficiency, but it also requires frequent filter screen replacements, increasing equipment maintenance costs and operating energy consumption, which seriously restricts the long-term stable operation of the dust recovery system.

[0032] To address this issue, this utility model provides a dust recovery device for use in cat litter production lines, solving the problems in the existing technology. This utility model solves the problem in the following ways.

[0033] Example 1: Please refer to the instruction manual appendix. Figures 1 to 8 As shown in the figure, this embodiment provides a dust recovery device for a cat litter production line. The device includes at least a housing 1, a dust filter 2, a dust filter frame 5, and a vibration mechanism 4. The housing 1 is equipped with support feet for support on a support surface (e.g., the ground). The dust filter 2 is fixed to the dust filter frame 5. The dust filter 2 is hollow and has a through-hole design, with its top and bottom ends fixed by a cap. The cap and the dust filter 2 together form a closed ventilation chamber capable of blocking dust. A support member is provided on the cap, which is fixed to the inner wall of the housing 1, allowing the dust filter 2 to be placed inside the housing 1 and dividing the internal chamber of the housing 1 into a first chamber 11 and a second chamber 12.

[0034] like Figures 1 to 2As shown, in this embodiment, the outer casing 1 is further provided with a dust inlet pipe 13, a dust outlet pipe 14, and an air outlet pipe 15. The dust inlet pipe 13 and the dust outlet pipe 14 are connected to the first chamber 11. The dust inlet pipe 13 is connected to the dust collection hood of the cat litter production device. The dust outlet pipe 14 is located below the outer casing 1, and is equipped with a switch valve and connected to the collection component. The air outlet pipe 15 is connected to the second chamber 12, and its other end is connected to an exhaust fan for exhausting the air in the second chamber 12.

[0035] Therefore, such as Figure 8 As shown in this embodiment, after the cat litter is produced on the cat litter production line, it contains a large amount of dust. This dust is separated from the cat litter through processes (e.g., sieving, vibration) and dispersed into the air. It is then adsorbed by the dust collection hood and its negative pressure device, and thus enters the interior of the first chamber 11 from the dust inlet pipe 13 (e.g., Figure 8 (As indicated by the dashed arrow in direction a). Dust enters the first chamber 11 with the air and is intercepted by the dust filter 2, accumulating on the filter 2. Clean air then passes through the dust filter 2 and enters the second chamber 12, passing through... Figure 8 The dust flows in the direction of the dotted arrow (c) and is eventually discharged from the outlet duct 15. When dust accumulates to a certain level, the rapping mechanism 4, located in the second chamber 12, is activated to vibrate the dust filter frame 5. The vibration of the dust filter frame 5 is transmitted to the dust filter screen 2, causing it to vibrate and shake off the accumulated dust. The dust then flows away due to gravity. Figure 8 The arrow pointing in the direction of b shows the dust falling out and eventually flowing out of the dust outlet pipe 14, where it is collected by the collection component.

[0036] Example 2: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 4 to 7 As shown, in this second embodiment, The second chamber 12 contains a rotating shaft 3 driven by a motor 6 (the motor 6 is fixed to the outer casing 1). The rotating shaft 3 is fixed to a spiral auger 31 via a frame. The rapping mechanism 4 is located in the second chamber 12 and includes several rapping blocks 41 that rotate within the second chamber 12. Each of these rapping blocks 41 is rotatably connected to a fixed block, which is fixed to the spiral auger 31 and evenly distributed from top to bottom. One end of a tension spring 42 is connected to the end of the rapping block 41 away from the fixed block, and the other end is connected to the fixed block.

[0037] Furthermore, the connection point between the tension spring 42 and the fixing block is located on the side of the fixing block closer to the rotation direction of the vibrating block 41 (and on this side, a limiting piece is also provided on the fixing block to prevent the vibrating block 41 from rotating excessively; when the vibrating block 41 abuts against the limiting piece, it stops rotating, at which point the tension spring 42, the vibrating block 41, and the limiting piece are in balance). Simultaneously, the dust filter frame 5 includes several evenly arranged fixing rings 51, and the dust filter 2 is fixed to the outer periphery of the fixing rings 51. Several first support pillars 52 and second support pillars 53 are also fixed on the fixing rings 51. The arrangement direction of the first support pillars 52 and the second support pillars 53 is along the rotation direction of the vibrating block 41; that is, during the rotation process, the vibrating block 41 first contacts the first support pillar 52 and then contacts the second support pillar 53.

[0038] Therefore, in the specific implementation of this second embodiment, when the vibrating block 41 does not contact the first support column 52, under the influence of the tension spring 42, the vibrating block 41 is in the following position. Figure 6 The state shown is as follows. At this time, the motor 6 drives the rotating shaft 3 to rotate, which in turn drives the auger 31 to rotate, and the vibrating block 41 rotates accordingly. When the vibrating block 41 touches the first support column 52, it is abutted by the first support column 52, and the vibrating block 41 rotates around the connection position with the fixed block until it releases the abutment with the first support column 52 during continuous rotation. At this time, the tension spring 42 is stretched and deformed.

[0039] When the rapping block 41 completely releases its contact with the first support column 52 and turns to the second support column 53, the tension spring 42 suddenly loses its contact force, thus quickly resets under the action of its deformation force, and drives the rapping block 41 to rotate rapidly. The rapping block 41 generates potential energy during the rapid rotation process. This potential energy is released when the rapping block 41 contacts the second support column 53, causing the second support column 53 to vibrate. During the vibration process, the second support column 53 gradually transmits the vibration force from the fixed ring 51 to the connected dust filter 2, eventually causing the dust filter 2 to vibrate, thereby shaking off the dust adsorbed on it.

[0040] Example 3: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides a third embodiment. In this third embodiment, a flexible layer is provided on the rapping block 41, the first support column 52, and the second support column 53. This flexible layer can be made of silicone material or foam material, and its function is to buffer the second support column 53 when the rapping block 41 rapps onto the second support column 53, absorbing part of the vibration force, thereby providing a certain degree of protection for the second support column 53 and the rapping block 41, and reducing noise. However, it should be noted that the absorbed vibration force should be less than the vibration force generated by the rapping block 41 on the second support column 53, so that the dust filter 2 can vibrate and shake off the dust.

[0041] Furthermore, in this third embodiment, a preferred embodiment is that a plurality of rollers or balls are rotatably provided on the surfaces of the vibrating block 41 that respectively contact the first pillar 52 and the second pillar 53. These rollers or balls roll when they contact the first pillar 52 and the second pillar 53, thereby reducing the friction generated when the vibrating block 41 contacts the first pillar 52 and the second pillar 53.

[0042] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to: This invention uses a vibrating block 41 to vibrate the dust filter frame 5, causing the dust filter frame 5 to vibrate. The vibration of the dust filter frame 5 drives the dust filter screen 2 to vibrate, causing the dust collected on the dust filter screen 2 to fall off and be collected. This design avoids damage to the mesh caused by the vibrating mechanism 4 directly acting on the dust filter screen 2, thus improving the service life of the dust filter screen 2.

[0043] Next, this utility model uses a spiral auger 31 to connect the vibrating block 41, so that the vibrating block 41 is evenly distributed on the spiral auger 31. During the rotation process, the spiral auger 31 drives the vibrating block 41 to vibrate the upper and lower parts of the dust filter frame 5, which avoids the problem in the prior art where the vibrating mechanism 4 acts only on a certain filter part, resulting in poor dust shaking effect in other parts.

[0044] In addition, this utility model also utilizes the first pillar 52 and the second pillar 53 to connect several fixing rings 51, so that after the first pillar 52 and the second pillar 53 are vibrated by the vibrating block 41, their vibration force is distributed to various parts of the dust filter frame 5, avoiding fatigue problems caused by excessive vibration stress concentration during long-term use.

[0045] Finally, the vibrating block 41 of this utility model is limited by the tension spring 42, so that it rotates when it contacts the first support column 52. At this time, the tension spring 42 is stretched. When the vibrating block 41 is separated from the first support column 52, the vibrating block 41 is reset under the action of the tension spring 42 and then strikes the second support column 53. This design allows the vibrating mechanism 4 to vibrate the dust filter frame 5 without an additional driving device, thus improving the stability of the vibrating.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
