Description

Technical Field

[0001] The invention relates to the technical field of cat litter, and in particular to a cat litter using phosphogypsum as a raw material and a preparation method and a processing method thereof. Background Art

[0002] Cat litter is an object used by pet owners to bury feces and urine for their cats. It has good water absorption, low dust and deodorization properties. Cat litter will condense into clumps when it comes into contact with water, making it easier for pet owners to scoop out and clean feces. Cat litter is a must-have for cats. It is a fast-moving consumer product with rigid demand, repeat purchases, and high frequency among pet cleaning products. With the increase in the number of pet cats, the demand for cat litter is also increasing, and there are more and more varieties. At present, common cat litter varieties include bentonite cat litter, tofu cat litter, silica gel cat litter, mixed cat litter, and cat litter made of other raw materials.

[0003] Bentonite cat litter has the advantage of good water absorption and agglomeration. However, it produces a lot of dust during use, and its deodorizing ability is poor, so it needs to be covered with spices. It is not easily soluble in water and has precipitation. It cannot be directly poured into the toilet and flushed away, so it can only be discarded as domestic garbage when cleaning. It also has a strong odor and is not very convenient to clean. It has a large daily consumption, but it is cheap.

[0004] Tofu cat litter originated in Japan. Its name comes from the bean dregs contained in the basic raw materials of soy products. Features: good water absorption, can be quickly dissolved in water, can be directly poured into the toilet and flushed away, very convenient to clean. Good clumping. It is easy to powder when exposed to moisture during use, and it is easy to ferment and produce odor when exposed to heat and moisture. It is easy to clumping and stick to the bottom. It is not deodorized and needs to add spices to cover it. It is consumed in large quantities for daily use and has a high price.

[0005] The main component of silica cat litter is silicon dioxide. Features: Super fast moisture absorption, high appearance. It changes color after absorbing water and is easy to distinguish. It has low dust and strong antibacterial and deodorizing ability, but it does not clump. After use, it is necessary to discard the whole basin and replace it with a new cat litter according to the color change. It is insoluble in water and is inconvenient to clean. The cat litter particles are hard and prickly. The daily consumption is small, but the price is high.

[0006] Mixed cat litter is a mixture of bentonite, tofu cat litter and deodorizing ingredients in a certain proportion to achieve the function of complementary performance advantages, while having a beautiful profit margin. Features: good water absorption, a small amount can be flushed down the toilet, good clumping, small dust, good deodorizing ability. Moderate consumption, moderate price, is currently the mainstream product in the domestic and Southeast Asian cat litter market.

[0007] We found in the experimental research on the reuse of phosphogypsum that phosphogypsum cat litter has the advantage of replacing similar cat litter products on the market in terms of performance. Phosphogypsum cat litter particles can quickly agglomerate when in contact with water, achieving the effect of absorbing cat urine. The improved phosphogypsum cat litter has unique chemical properties, can be naturally antibacterial and deodorizing, and has the unique characteristics of a soil conditioner. The agglomerated phosphogypsum cat litter can be converted into nutritious soil and discarded as domestic garbage, which is green, environmentally friendly and pollution-free. Therefore, it is basically feasible to convert phosphogypsum into cat litter. Based on this, the present invention provides a cat litter using phosphogypsum as a raw material, a preparation method thereof, and a processing method thereof. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a cat litter using phosphogypsum as a raw material and a preparation method and a processing method thereof. The cat litter prepared by the present invention is naturally antibacterial and deodorizing, and has the unique characteristics of a soil conditioner. The agglomerated phosphogypsum cat litter can be converted into nutritious soil and discarded as domestic waste, which is green, environmentally friendly and pollution-free.

[0009] In order to solve the above technical problems, the technical solution of the present invention is: a cat litter with phosphogypsum as raw material, characterized in that the cat litter is prepared with phosphogypsum as the main raw material by adding an organic binder and an inorganic binder.

[0010] Preferably, the composition comprises, by weight: 80-90 parts of phosphogypsum, 5-15 parts of organic binder, and 2-5 parts of inorganic binder.

[0011] Preferably, the composition includes, by weight percentage: 95 parts of phosphogypsum, 3 parts of organic binder, and 2 parts of inorganic binder.

[0012] Preferably, the organic binder is one or more of sodium carboxymethyl cellulose (CMC), guar gum or plant gum powder.

[0013] Preferably, the inorganic binder is one or more of water glass, limestone or cement.

[0014] The present invention also discloses a method for preparing cat litter using phosphogypsum as raw material, the method comprising the following steps:

[0015] (1) Preliminary mixing: weigh phosphogypsum and organic binder according to weight parts, and mix the two uniformly to obtain premix A;

[0016] (2) Aqueous solution preparation: adding an inorganic binder to water according to a certain proportion to form a premixed slurry B;

[0017] (3) Mixing: adding the premixed slurry B obtained in step (2) into step (1), and then mixing the two to obtain a primary mixture C;

[0018] (4) Granulation and screening: Use a disc or drum granulator to granulate the primary mixture C, with a granulation diameter of 2-5 mm;

[0019] (5) Drying: The temperature is controlled to be below 50°C for drying to obtain phosphogypsum cat litter.

[0020] Preferably, the drying temperature in step (5) is 30-50°C.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Performance advantages: Phosphogypsum cat litter has excellent water absorption due to its main component of gypsum. Its advantage is that it can absorb pet urine and wrap feces in a short period of time, and decompose the odor emitted by cat urine. The pH value of phosphogypsum cat litter is weakly acidic, which can naturally strangle bacteria, keep the surface of the cat litter dry and clean, and keep the pet's defecation environment hygienic and safe.

[0023] 2. Environmental advantages: The improved phosphogypsum cat litter has unique chemical properties, can naturally inhibit bacteria and deodorize, and has the unique characteristics of a soil conditioner. After mixing with cat feces, it undergoes a chemical reaction and can be converted into organic nutrient soil. It can be discarded as domestic waste, which is green, environmentally friendly and pollution-free.

[0024] 3. Safety advantage: Safety is a red line in product development. Phosphogypsum cat litter must not have safety hazards, because safety hazards are a high-voltage line in the pet industry and are not allowed to be touched. The cat litter of the present invention will be strictly implemented in accordance with the new national standard in production, and will cooperate with third-party testing agencies to conduct regular sampling and testing to ensure the safety of product use. At present, the test safety data of phosphogypsum cat litter laboratory products are all up to standard. The Pb content of phosphogypsum cat litter is 12.70 mg / kg, and the As content is 4.83 mg / kg, which is far lower than the standard limit of the "Technical Requirements for Safety of Companion Animal (Pet) Products" approved and issued by the State Administration for Market Regulation.

[0025] 4. Advantage of stable production capacity: The stable production capacity and output of products are the basic principles of market supply, so they have stability and continuous supply. The existing reserves of phosphogypsum in Guizhou will not be restricted by various other market factors, and are strongly supported by policies. In terms of technology, Guizhou's phosphorus chemical technology is at the forefront of the industry in the country, ensuring the stability of the raw material composition of phosphogypsum. In terms of the production capacity of phosphogypsum cat litter, the cat litter production process and market expansion and running-in are mature, and we can unite multiple key phosphogypsum production areas in Guizhou to jointly create a "Guizhou phosphogypsum cat litter supply system". The reserves of hundreds of millions of tons of phosphogypsum raw materials are sufficient to cope with changing market demands.

[0026] 5. Complementary performance advantages: By comparison, it is found that the performance of phosphogypsum cat litter is superior and more stable than that of cat litter on the current market. It can be mixed with cat litter products made of other raw materials to complement and enhance the comprehensive performance advantages, making the use of cat litter more effective and the profit margin of sales channels more stable.
