Description

Technical Field

[0001] The invention relates to the technical field of cat litter materials, and in particular to a novel bentonite strip cat litter and a preparation method thereof. Background Art

[0002] Cat litter is an object used by cat owners to bury feces and urine, and has good water absorption. With the rise of pet cats and pet economy in China, the sales of China's cat litter industry have increased year by year, and the demand for cat litter in China has increased sharply. Pet families pay more attention to the health of their pets year by year. The quality of cat litter is related to user experience and pet health. At present, the mainstream bentonite cat litter in the market is mainly crushed sand and spherical sand. Both of these products have a large specific gravity, large dust, poor agglomeration strength, severe powdering, poor deodorization performance, short use cycle, and high frequency of sand replenishment, which affects pet health and user experience. Summary of the invention

[0003] The invention aims to provide a novel bentonite strip cat litter and a preparation method thereof, which can maintain the original mineral properties of bentonite, has strong deodorizing performance, high water absorption expansion multiple, easy agglomeration, high strength, not easy to powder, small dust, relatively small specific gravity, long service life, and overcomes the defects of existing bentonite cat litter, such as large specific gravity, large dust, poor agglomeration strength, serious powdering, poor deodorizing performance, short service life and high sand replenishing frequency.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: A novel bentonite strip cat litter comprises the following raw materials in parts by weight: 80-90 parts by weight of high-purity sodium-based bentonite and 10-20 parts by weight of soda ash solution.

[0005] Preferably, the cat litter is cylindrical particles, and the diameter of the cylindrical particles is 1.5-2.5 mm.

[0006] The present invention also provides a method for preparing the novel bentonite strip cat litter, comprising the following steps: S1. Mixing raw materials: Take 80-90 parts by weight of high-purity sodium bentonite and 10-20 parts by weight of soda ash solution, and stir the above raw materials evenly with a planetary mixer to form a mixture; S2, granulation: the mixed material is extruded and granulated by a ring die granulator and a fixed aperture die to produce cylindrical bentonite granule wet material; S3, drying: drying the cylindrical bentonite particles at a temperature of 300°C through a drum drying device to form bentonite cat litter strips; S4. Dust removal: The dust remaining on the surface of bentonite cat litter strips is removed through screening and induced draft equipment to reduce product dust.

[0007] In summary, the beneficial effects of the present invention are as follows: the present application uses a ring die granulator and a fixed aperture die to extrude and granulate a mixture of high-purity sodium-based bentonite and sodium carbonate solution, uses a drum drying device to dry the granulated wet material to form cat litter, and uses screening and induced draft equipment to remove dust from the dried cat litter. The prepared cat litter has strong deodorizing performance, high water absorption and expansion multiples, is easy to agglomerate, has high strength, has low dust, has a relatively small specific gravity, has a long service life, reduces the frequency of litter replenishment, ensures the health of pets, and improves the user experience.
