Description

Technical Field

[0001] This solution belongs to the field of cat litter processing equipment, specifically involving a cat litter raw material pretreatment device. Background Technology

[0002] As an essential pet care product, cat litter continues to see a growing market demand. Common cat litter raw materials, such as bentonite, tofu residue, corn cobs, and pulp, typically require pretreatment before being processed into finished products. Crushing is one of the key processes, aiming to process the raw materials into uniform, fine particles to meet performance requirements such as clumping and absorbency.

[0003] A search revealed that in the invention patent application with publication number CN114051939A, a deodorizing cat litter and a raw material crushing device for processing it are disclosed. The device includes a fixed frame, a crushing mechanism for crushing cat litter raw materials is installed on the fixed frame, a drive mechanism connected to the crushing mechanism is installed on the fixed frame, an anti-clogging mechanism is installed on the crushing mechanism, the anti-clogging mechanism abuts against the drive mechanism, and a material storage mechanism is installed on the fixed frame.

[0004] In existing technologies, the single-stage crushing of raw materials can easily result in uneven particle size, affecting the quality of the final product. At the same time, the components used for particle screening are easily clogged by raw materials, thus affecting the continuity and stability of the processing. Utility Model Content

[0005] The purpose of this solution is to provide a cat litter raw material pretreatment device to solve the problem that uneven particle size is easily caused by single crushing of raw materials in the existing technology, which affects the quality of the final product. At the same time, it solves the problem that the components used for particle screening are easily blocked by raw materials, thus affecting the continuity and stability of processing.

[0006] To achieve the above objectives, this solution provides a cat litter raw material pretreatment device, including a crushing box. A flow guide hood is fixedly connected to the middle of the inner side of the crushing box. The flow guide hood is funnel-shaped. A transition pipe is connected to the side wall of the flow guide hood. The transition pipe is inclined and passes through the crushing box and extends to the outside of the crushing box. A conveying cylinder is connected to the end of the transition pipe. The conveying cylinder is vertically arranged. A motor is fixedly installed on the top of the conveying cylinder. The output shaft of the motor passes through the conveying cylinder and is connected to the conveying cylinder through a bearing. A spiral conveying shaft is fixedly connected to the end of the output shaft of the motor. The end of the spiral conveying shaft is connected to the conveying cylinder through a bearing. A filter disc is slidably connected to the inner side of the flow guide hood. The filter disc is inclined. An inclined seat is fixedly connected to the upper surface of the filter disc. An elastic support mechanism is provided below the filter disc.

[0007] The principle of this solution is as follows: During use, lumpy or granular cat litter material is fed into the top of the grinding chamber. Simultaneously, motor two is started, driving the rotating shaft and moving grinding blades to rotate at high speed. The moving grinding blades shear against the stationary grinding blades fixed inside the grinding chamber, initially crushing the material. The initially crushed material falls onto an inclined filter plate. Fine powder meeting the particle size requirements passes through the sieve holes of the filter plate and is discharged from the bottom of the grinding chamber. As the rotating shaft rotates, its lower end's irregularly shaped rod rotates with the shaft and engages with the inclined seat on the filter plate, providing a periodic downward force to the filter plate. The elastic support mechanism below the filter plate... The material is compressed under the force and reset by the spring rebound force after the shaped rod rotates. This process repeats, causing the filter disc to vibrate continuously, effectively preventing fine powder from clogging the screen holes and ensuring screening efficiency. Larger particles that fail to pass through the screen holes slide down the inclined surface of the filter disc and flow into the conveying cylinder through the transition pipe on the side wall of the guide hood. The motor drives the screw conveyor shaft to rotate and lifts the larger particles upward. After being lifted to the top of the conveying cylinder, the material flows back to the top of the crushing box through the connecting return pipe for secondary crushing until all raw materials are crushed to the qualified fineness.

[0008] The technical advantages of this solution are as follows: By setting a rotating shaft driven by a motor, the moving pulverizing blades on the rotating shaft and the stationary pulverizing blades in the pulverizing chamber cooperate to pulverize the raw materials. At the same time, the filter disc can screen the pulverized raw materials, realizing an integrated structure of pulverization and screening. In addition, an inclined seat is set on the filter disc, and a matching elastic support mechanism is set at the bottom. A corresponding irregular rod is set on the rotating shaft. Through the cooperation of the irregular rod and the inclined seat, the filter disc can vibrate periodically, which can prevent the filter disc from clogging itself, thereby ensuring the stable operation of screening.

[0009] By setting a transition pipe extending to the outside of the crushing box on the side of the guide shroud, the auger assembly consisting of the transition pipe, the conveying cylinder, the motor, the screw conveyor shaft, and the return pipe can automatically transport larger particles that do not meet the standards after the initial crushing back to the crushing box for secondary crushing, thereby improving the finished product yield of the crushing.

[0010] Furthermore, multiple brackets are fixedly connected to the upper outer side of the crushing box, and a support base is fixedly connected to these brackets. A second motor is fixedly installed at the upper center of the support base. The output shaft of the second motor passes through the support base and is connected to it via a bearing. A rotating shaft is fixedly connected to the end of the output shaft of the second motor. Multiple moving crushing blades are fixedly connected to the shaft body of the rotating shaft. Multiple stationary crushing blades are fixedly connected to the inner wall of the crushing box, and the positions of the stationary crushing blades correspond to the positions of the moving crushing blades. A special-shaped rod, L-shaped, is fixedly connected to the lower section of the rotating shaft, and the end of the special-shaped rod abuts against the inclined surface of the inclined seat. By rotating the rotating shaft with the second motor, the rotating shaft drives the moving crushing blades to rotate. The moving and stationary crushing blades cooperate to crush the raw materials. Simultaneously, the rotating shaft drives the special-shaped rod to rotate, and the special-shaped rod, through its cooperation with the inclined seat, generates a periodic downward thrust on the filter disc.

[0011] Furthermore, a return pipe is connected to the upper side wall of the conveying cylinder. The return pipe is inclined and located above the crushing box. Through the return pipe, larger particles of raw material conveyed by the conveying cylinder and the screw conveyor shaft can be re-transported into the crushing box for secondary crushing.

[0012] Furthermore, the elastic support mechanism includes two fixed rods fixedly connected to the inner wall of the pulverizing chamber. A support block is fixedly connected between the two fixed rods. A guide sleeve is fixedly connected to the upper end of the support block. A guide post is slidably connected to the inner side of the guide sleeve. The top of the guide post is fixedly connected to the lower surface of the filter disc. Through the setting of the elastic support mechanism, the filter disc is provided with elastic support.

[0013] Furthermore, a spring is provided inside the guide sleeve. One end of the spring is fixedly connected to the guide post, and the other end of the spring is fixedly connected to the bottom inner side of the guide sleeve. The spring allows the elastic force to act on the filter disc through the guide post, thus assisting in its repositioning.

[0014] Furthermore, a conical ring is fixedly connected to the column of the guide post, and a fixing ring is fixedly connected to the outer side of the guide sleeve. A protective sleeve is fixedly connected between the fixing ring and the conical ring. The protective sleeve provides protection for the spring.

[0015] Furthermore, a support ring is fixedly connected to the lower outer side of the crushing box, and multiple support legs are fixedly connected to the bottom of the support ring. The bottom of the conveying cylinder is fixedly connected to the support ring. The support ring and support legs provide overall support. Attached Figure Description

[0019] like Figure 1 , Figure 2As shown, multiple brackets 10 are fixedly connected to the upper outer side of the crushing box 1. A support base 11 is fixedly connected to the multiple brackets 10. A second motor 12 is fixedly installed in the middle of the upper end of the support base 11. The output shaft of the second motor 12 passes through the support base 11 and is connected to the support base 11 through a bearing. A rotating shaft 13 is fixedly connected to the end of the output shaft of the second motor 12. Multiple moving crushing blades 14 are fixedly connected to the shaft of the rotating shaft 13. Multiple stationary crushing blades 15 are fixedly connected to the inner wall of the crushing box 1. The position of the stationary crushing blades 15 corresponds to the position of the moving crushing blades 14. A special-shaped rod 16 is fixedly connected to the lower section of the shaft of the rotating shaft 13. The special-shaped rod 16 is L-shaped. The end of the special-shaped rod 16 abuts against the inclined surface of the inclined seat 81. The rotating shaft 13 is rotated by the motor 12, which drives the moving crushing blade 14 to rotate. The moving crushing blade 14 cooperates with the stationary crushing blade 15 to crush the raw materials. At the same time, the rotating shaft 13 will drive the shaped rod 16 to rotate. The shaped rod 16, through cooperation with the inclined seat 81, can generate a periodic downward thrust on the filter disc 8.

[0020] like Figure 2 , Figure 5 As shown, a filter disc 8 is slidably connected to the inner side of the flow guide shroud 2, and the filter disc 8 is inclined. An inclined seat 81 is fixedly connected to the upper surface of the filter disc 8, and an elastic support mechanism 9 is provided below the filter disc 8. The elastic support mechanism 9 provides elastic support for the filter disc 8.

A protective sleeve 98 is fixedly connected between the fixing ring 97 and the conical ring 96. The protective sleeve 98 provides protection for the spring 95.

[0021] The specific implementation process of this utility model is as follows: In use, blocky or granular cat litter material is fed into the top of the crushing box 1. Simultaneously, the second motor 12 is started. The second motor 12 drives the rotating shaft 13 and the moving crushing blade 14 to rotate at high speed. The moving crushing blade 14 shears against the stationary crushing blade 15 fixed inside the crushing box 1, performing preliminary crushing of the material. The pre-crushed material falls onto the inclined filter disc 8. Fine powder meeting the particle size requirements passes through the sieve holes of the filter disc 8 and is discharged from the bottom of the crushing box 1. While the rotating shaft 13 rotates, its lower end's shaped rod 16 rotates with the shaft and cooperates with the inclined seat 81 on the filter disc 8, giving the filter disc 8 a periodic downward force. The elastic support mechanism 9 below is compressed under the action of this force and reset under the rebound force of the spring 95 after the shaped rod 16 has rotated. This process repeats, causing the filter disc 8 to vibrate continuously, effectively preventing fine powder from clogging the screen holes and ensuring screening efficiency. Larger particles that fail to pass through the screen holes of the filter disc 8 will slide down the inclined surface of the filter disc 8 and flow into the conveying cylinder 4 through the transition pipe 3 on the side wall of the guide hood 2. The motor 5 drives the screw conveyor shaft 6 to rotate and lifts the larger particles upward. After being lifted to the top of the conveying cylinder 4, the material flows back to the top of the crushing box 1 through the connected return pipe 7 for secondary crushing until all raw materials are crushed to the qualified fineness.

[0022] This solution uses a rotating shaft 13 driven by a motor 12. The moving pulverizing blade 14 on the rotating shaft 13 works in conjunction with the stationary pulverizing blade 15 in the pulverizing box 1 to pulverize the raw materials. Simultaneously, the filter disc 8 can screen the pulverized raw materials, achieving an integrated structure for pulverization and screening. In addition, an inclined seat 81 is provided on the filter disc 8, and a matching elastic support mechanism 9 is provided at the bottom. A corresponding irregular rod 16 is provided on the rotating shaft 13. Through the cooperation of the irregular rod 16 and the inclined seat 81, the filter disc 8 can vibrate periodically, which can prevent the filter disc 8 from clogging itself, thereby ensuring the stable operation of screening.

[0023] By setting a transition pipe 3 extending to the outside of the crushing box 1 on the side of the guide shroud 2, the auger assembly consisting of the transition pipe 3, the conveying cylinder 4, the motor 5, the screw conveying shaft 6, and the return pipe 7 can automatically transport larger particles that do not meet the standards after the initial crushing back to the crushing box 1 for secondary crushing, thereby improving the finished product yield of the crushing.
