Description

Technical Field

[0001] This utility model relates to the field of cat litter processing technology, specifically a cat litter crushing and screening machine with a dust removal system. Background Technology

[0002] Cat litter is a product designed to address a cat's natural instinct to bury its feces and urine. Bentonite, a type of clay mineral, possesses excellent water absorption, binding, and adsorption properties, making it suitable for use in cat litter. Due to its inherent properties, bentonite cat litter clumps together when wet and has a certain ammonia-absorbing capacity, making it convenient for owners to handle their cats' urine and feces, maintaining a clean and tidy indoor environment. Bentonite cat litter generally comes in two types: spherical litter and crushed litter. The production process for crushed bentonite cat litter is relatively simple, requiring sodium-based bentonite to be crushed to a certain particle size and then sieved.

[0003] For example, Chinese utility model patent CN222034924U discloses a crushing and screening machine for bentonite cat litter, belonging to the field of crushing and screening technology. This utility model solves the problem that existing crushing and screening devices can only complete one crushing and one screening, and cannot automatically achieve secondary crushing and re-screening. This utility model includes a housing, a crushing mechanism, a screening mechanism, and a screw conveyor mechanism. The crushing and screening mechanisms are arranged sequentially from top to bottom within the housing. The screening mechanism includes an upper discharge port and a lower discharge port. The input end of the screw conveyor mechanism is connected to the upper discharge port, and the lower discharge port is connected to the first discharge port. The input end of the screw conveyor mechanism is located between the top of the housing and the crushing mechanism. This utility model realizes an integrated process of crushing-screening-re-crushing-re-screening, improving product quality and output, achieving automation, and reducing the labor intensity of operators.

[0004] However, existing cat litter crushing and screening machines have a powder discharge port. The powder is taken out from the bottom of the box through the powder discharge port. When the powder falls from the powder discharge port, it can easily cause dust to spread and pollute the working environment.

[0005] Therefore, we propose a cat litter crushing and screening machine with a dust removal system to solve the above problems. Utility Model Content

[0025] Please see Figure 1-5In use, the motor 7 is connected to an external power source. Starting the motor 7 drives the rotating rod 8, gear 9, and crushing roller 12 to rotate, simultaneously driving the gear 10, rotating rod 11, and crushing roller 12 on the other side to rotate. The cat litter material to be crushed can be fed into the feed inlet 4. The crushing roller 12 crushes and pulverizes the cat litter material. The crushed cat litter material can be screened through the filter screen plate 13. The screened cat litter material is then guided into the discharge pipe 2 through the guide block 22 and the discharge port 23. 4. Simultaneously, the exhaust fan 29 is connected to an external power supply. By starting the exhaust fan 29, dust in the cat litter can be sucked out through the dust suction hood 34 during the process of the cat litter being discharged from the discharge pipe 24. The filter screen 35 set in the dust suction hood 34 effectively prevents the cat litter from being sucked into the dust suction hood 34 and can also filter particulate impurities in the sucked dust, improve the dust removal effect, and reduce the impact on the working environment. The cat litter can be discharged through the discharge pipe 24, which can reduce the spread and overflow of dust during the discharge process. When the filter screen 35 needs to be cleaned, the cylinder 26 is connected to an external power source. By starting the cylinder 26, the moving block 28, the exhaust fan 29, the air inlet pipe 33, and the air outlet pipe 32 are moved, so that the air inlet pipe 33 is disengaged from the rubber pad 41.
