A material receiving device for cat litter production

Abstract

This utility model discloses a receiving device for cat litter production, including an inclined outer shell. The top and bottom of the outer shell have inlet and outlet holes, respectively. A powder storage box is detachably connected to the bottom of the rear surface of the outer shell. A disc is rotatably connected inside the outer shell. A limiting cylinder is vertically installed in the center of the front surface of the disc. Multiple vertical plates are evenly installed on the front surface of the disc, and rubber pads are attached to the surfaces of the disc and the vertical plates. Through holes are evenly distributed on the disc and the rubber pads. The inclined outer shell design guides the cat litter to slide along the inner wall, avoiding violent impacts from vertical falls. Simultaneously, the rubber pads attached to the surfaces of the vertical plates and the disc absorb the impact force, reducing direct contact between the cat litter and hard components, significantly reducing particle breakage and the generation of fine debris, ensuring the integrity and quality stability of the finished product particles. This device is particularly suitable for cat litter types with high brittleness, such as bentonite and tofu litter.

Description

Technical Field

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

[0002] In the industrial production process of cat litter, the receiving stage is a crucial node connecting the processing steps with subsequent storage and packaging. The performance of its equipment directly affects the quality of the finished cat litter and the production environment. Currently, the receiving methods commonly used in the industry have significant drawbacks.

[0003] On the one hand, when cat litter falls directly from the discharge end of the processing equipment onto the receiving platform or conveying device, the lack of a buffer structure causes the litter particles to collide violently with the hard platform surface, easily leading to particle breakage and the generation of a large amount of fine debris. This not only reduces the yield of qualified cat litter, but the broken fine particles also further increase the dust content, affecting the stability of product quality.

[0004] On the other hand, the dust generated from cat litter raw materials and processing lacks effective collection and restraint during its fall and transportation. Traditional receiving devices are mostly open or simple enclosed structures, allowing dust to easily drift into the production workshop through gaps. This not only pollutes the working environment and harms the respiratory health of operators, but also may cause equipment malfunctions or safety hazards due to dust accumulation. Furthermore, the drifting dust adheres to the surfaces of production equipment, requiring additional manpower for cleaning and maintenance, increasing production management costs.

[0005] Therefore, a receiving device for cat litter production is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a receiving device for cat litter production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a receiving device for cat litter production, comprising an inclined outer shell, wherein the top and bottom of the outer shell are respectively provided with a feed hole and a discharge hole, and a powder storage box is detachably connected to the bottom of the rear surface of the outer shell;

[0008] The outer shell is rotatably connected to a disc. A limit cylinder is vertically installed in the middle of the front surface of the disc. Multiple vertical plates are evenly installed on the front surface of the disc. Rubber pads are attached to the surface of the disc and the multiple vertical plates. Through holes are evenly opened on the disc and the rubber pads.

[0009] Preferably, a connecting cylinder is coaxially mounted on the middle of the rear surface of the disc, the connecting cylinder is rotatably connected to the middle of the rear surface of the outer shell, and one end of the connecting cylinder penetrates the rear surface of the outer shell and is equipped with a drive wheel.

[0010] Preferably, the drive wheel is a pulley, sprocket, or gear.

[0011] Preferably, there is a gap between the disc and the inner bottom wall of the outer shell to facilitate dust discharge, and a cleaning brush for sweeping dust is installed on the rear surface of the disc.

[0012] Preferably, a limiting ring is installed in the middle of the inner front wall of the outer shell, and the limiting ring is located inside the limiting cylinder.

[0013] Preferably, both the feed port and the discharge port are equipped with hoppers.

[0014] Preferably, a door is installed on one side of the powder storage box.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the inclined shell design guides the cat litter to slide along the inner wall, avoiding violent impacts from vertical falls; at the same time, the rubber pads that fit between the upright plate and the disc surface can absorb the impact force of falling, reduce the direct contact between the cat litter and hard parts, significantly reduce particle breakage and the generation of fine debris, and ensure the integrity and quality stability of the finished particles, especially suitable for cat litter types with high brittleness such as bentonite and tofu litter.

[0016] The through-holes on the disc and rubber pad separate dust and fine particles from the cat litter. Combined with the gap between the disc and the bottom wall of the outer casing, this forms a directional dust channel. A cleaning brush on the rear surface of the disc rotates synchronously with the disc, continuously cleaning residual dust from the bottom wall to prevent accumulation and blockage, ensuring efficient dust collection in the powder storage box. The powder storage box is easily accessible through a door, preventing dust from spreading and contaminating the workshop, protecting operator health, and reducing equipment cleaning and maintenance costs.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-6 This utility model provides a technical solution: it includes an outer shell 1 with an inclination angle of 15-30°, an inlet hole 13 at the top of the outer shell 1 and an outlet hole 14 at the bottom; a powder storage box 2 is detachably connected to the bottom of the rear surface of the outer shell 1, and a disc 6 is rotatably connected inside the outer shell 1. The outer side wall of the disc 6 is in contact with the inner side wall of the outer shell 1. A limiting cylinder 8 is vertically installed in the middle of the front surface of the disc 6. 3-6 upright plates 7 are evenly installed along the circumferential direction on the front surface of the disc 6. The top of the upright plates 7 is in contact with the inner top wall of the outer shell 1. A rubber pad 9 with a thickness of 2-5mm is attached to the surface of the upright plates 7 and the disc 6. The rubber pad 9 is bonded and fixed to the upright plates 7 and the disc 6 by a high-temperature resistant adhesive layer. Multiple through holes 10 are evenly opened on the disc 6 and the rubber pad 9. The upright plates 7 are used to separate and form independent receiving chambers, which, together with the rotation of the disc 6, realize the intermittent receiving and directional conveying of cat litter. The rubber pad 9 can play a buffering role when the cat litter falls, avoiding hard contact. Through hole 10 is used to separate dust and fine powder particles from cat litter.

[0026] like Figure 3 As shown: A connecting cylinder 15 is coaxially mounted in the middle of the rear surface of the disc 6. The connecting cylinder 15 is rotatably connected to the middle of the rear surface of the outer shell 1 through a bearing. The end of the connecting cylinder 15 away from the disc 6 passes through the rear surface of the outer shell 1 and is equipped with a drive wheel 5. The drive wheel 5 drives the connecting cylinder 15 to rotate, providing a stable torque to the disc 6 and ensuring the continuous operation of the receiving chamber.

[0027] like Figure 2 As shown: Drive wheel 5 can be a pulley, sprocket, or gear, which can be flexibly matched with the drive system of different production lines.

[0028] like Figure 6 As shown: There is a gap between the disc 6 and the inner bottom wall of the outer shell 1. The gap is used to guide the dust to flow to the powder storage box 2. A cleaning brush 11 is installed on the rear surface of the disc 6. The cleaning brush 11 is made of nylon and the bristles are longer than the gap. When the cleaning brush 11 rotates with the disc 6, it can clean the residual dust on the bottom wall and prevent dust from accumulating and causing blockage.

[0029] like Figure 5As shown: A limiting ring 12 is welded to the middle of the inner front wall of the outer shell 1. The outer wall of the limiting ring 12 is provided with a polytetrafluoroethylene wear-resistant layer. The limiting ring 12 and the limiting cylinder 8 form a sliding fit. This structure can limit the axial movement of the disk 6 and improve the coaxiality of the disk 6 rotation.

[0030] like Figure 1 and Figure 2 As shown: Both the feed hole 13 and the discharge hole 14 are equipped with hoppers 3. The hoppers 3 are funnel-shaped and the inner walls are polished. The hoppers 3 are connected to the outer shell 1 by flange bolts, and a silicone sealing gasket is provided between the flanges. The hoppers 3 can expand the material receiving range, the polished inner walls reduce cat litter residue, and the sealing gaskets prevent dust from leaking from the connection gaps.

[0031] like Figure 2 As shown: A door 4 is installed on one side of the powder storage box 2. The edge of the door 4 is provided with a rubber sealing strip, and a handle is installed on the surface of the door 4.

[0032] like Figure 1 As shown: The inner wall of the outer casing 1 is coated with a polyurea wear-resistant coating; to ensure corrosion resistance, the polyurea coating can reduce the wear of cat litter on the inner wall and extend the service life of the equipment.

[0033] like Figure 4 As shown: The cleaning brush 11 can be detachably installed on the rear surface of the disc 6 via a snap-fit ​​structure, and the high-density bristles ensure thorough cleaning without any blind spots.

[0034] Working principle: When the cat litter raw material enters the outer shell 1 through the hopper 3 at the feed port 13, the outer shell 1, which is tilted at 15 to 30 degrees, allows the material to slide along the inner wall, preventing the cat litter from falling vertically and colliding violently with the equipment. At the same time, the funnel-shaped hopper 3 at the feed port 13 expands the receiving range, its polished inner wall reduces cat litter retention, and the silicone sealing gasket at the flange connection prevents dust from leaking out from the gaps.

[0035] When cat litter falls into the independent receiving chamber formed by the upright plate 7 on the front surface of the disc 6, the thick rubber pad 9 that is attached to the surface of the disc 6 by the upright plate 7 plays a key cushioning role. The elasticity of the rubber pad 9 can absorb the impact force of the falling cat litter, preventing the cat litter from directly contacting hard parts such as the upright plate 7 and the disc 6, and greatly reducing the breakage rate of cat litter caused by collision.

[0036] Regarding dust removal, dust and fine particles in the cat litter are separated through the through-holes 10 on the disc 6 and rubber pad 9. The gap between the disc 6 and the inner bottom wall of the outer casing 1 provides a channel for the dust, allowing it to converge towards the dust collection box 2 under gravity. The cleaning brush 11, mounted on the rear surface of the disc 6, rotates synchronously with the disc 6, cleaning residual dust on the bottom wall of the outer casing 1 in real time, preventing dust accumulation and blockage of the channel. The cleaning brush 11 features a snap-on, detachable design for easy replacement after wear, ensuring consistent and stable cleaning performance.

[0037] Finally, the separated dust is collected in the dust storage box 2 at the bottom of the rear surface of the outer shell 1. The door 4 on one side of the dust storage box 2 can be easily opened for regular dust cleaning. The cat litter, after being buffered and treated for dust removal, rotates with the receiving chamber to the bottom of the outer shell 1 and is discharged through the hopper 3 of the discharge hole 14, achieving stable delivery and efficient dust removal of the cat litter.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
