Description

Technical Field

[0001] The invention relates to the technical field of cat litter production, in particular to a strip cassava cat litter production line. Background Art

[0002] With the rapid development of the pet industry, cat litter, a necessity in cats' daily lives, continues to see growing market demand. While traditional cat litters, such as bentonite, have good clumping properties, their dustiness and non-degradability can negatively impact the environment and pet health. Paper cat litter is prone to shedding, while silica gel cat litter suffers from poor clumping properties and is non-recyclable.

[0003] In recent years, cassava cat litter has gained increasing attention for its natural biodegradability and low dust content. Cassava is a widely cultivated crop native to Brazil and also grown in large quantities in provinces and regions of my country, such as Guangdong, Hainan, and Fujian. Known as the "king of starch," cassava boasts a starch content of 70%-80%, with a significantly higher proportion of amylopectin than other plant-based starches. This allows the cassava cat litter to quickly form a tight network structure after absorbing water, resulting in compact clumps and a low sticking resistance. Furthermore, as a natural plant-based ingredient, cassava is green, environmentally friendly, and biodegradable, meeting the demands of modern consumers for sustainable development.

[0004] However, the existing cassava cat litter production process still has significant defects: traditional granulation processes (such as disc granulation and ring die granulation) have problems such as large dust, easy clogging of equipment, and poor particle uniformity; impurities are not thoroughly screened during the raw material pretreatment process, resulting in unstable product performance; additives are unevenly dispersed during the mixing process, affecting the deodorization and antibacterial effects; the drying process is inefficient and high temperatures can easily destroy the performance of the cat litter. In addition, the agglomeration efficiency of existing products is significantly reduced in humid environments, and dust control is insufficient (the dust content of bentonite cat litter is as high as 8mg / m 3 The particle shape is single and the specific surface area is limited, which limits the further improvement of water absorption and deodorization efficiency.

[0005] Therefore, there is an urgent need for an efficient, low-consumption, environmentally friendly cat litter production line to solve the above-mentioned technical bottlenecks and meet the market demand for high-performance cassava cat litter. Summary of the Invention

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1:

[0028] The present embodiment provides a strip cassava cat litter production line, such as Figure 1 As shown, it includes the following main functional units:

[0029] The raw material pretreatment unit is used to screen and weigh the raw materials. The raw material pretreatment unit includes a vibrating screen and a rotary vibrating screen. The rotary vibrating screen is connected to the rear end of the vibrating screen, and an intelligent metering scale is provided at the rear end of the rotary vibrating screen. The intelligent metering scale is connected to the mixing and stirring unit through an elevator 1. The combination of the vibrating screen and the rotary vibrating screen is used to first perform a coarse screening through the vibrating screen to remove large particles of impurities, and then a fine screening is performed with the rotary vibrating screen to ensure that the particle size of the raw materials is uniform. In combination with the intelligent metering scale, the input amount of each raw material is accurately controlled to ensure the accuracy of the formula. This improves the purity and uniformity of the raw materials, lays the foundation for subsequent production, reduces product quality problems caused by raw material differences, and accurate measurement helps reduce raw material waste.

[0030] Furthermore, the raw material pretreatment unit also includes a wet crushing device and a three-stage screening system. During the cassava raw material processing stage, wet crushing is used to reduce dust generation, and then three-stage screening is performed to control the dust generation during use to 0.8mg / m 3 Compared with traditional bentonite cat litter, the dust emission is reduced by 90%, effectively reducing indoor air pollution and protecting the respiratory health of cats and users;

[0031] The mixing and stirring unit is connected to the rear of the raw material pretreatment unit and is used to uniformly mix the pretreated raw materials; the mixing and stirring unit includes a single-shaft paddle mixer 2 and a vertical mixer 3, the single-shaft paddle mixer 2 is connected to the discharge end of the elevator 1, and the vertical mixer 3 is connected to the discharge end of the single-shaft paddle mixer 2; the single-shaft paddle mixer 2 and the vertical mixer 3 are combined in series, and the single-shaft paddle mixer 2 is first used for preliminary mixing, which can quickly and evenly stir a large amount of raw materials to achieve macroscopic mixing, and then fine mixing is carried out by the vertical mixer 3. The stirring paddle of the vertical mixer 3 rotates while revolving, which can achieve uniform mixing of materials on a smaller scale, and is especially suitable for mixing additives such as deodorants and antibacterial agents with smaller addition amounts; this combination can improve the uniformity of mixing while ensuring mixing efficiency, ensure that various raw materials and additives are fully mixed, and make the performance of cat litter products more stable;

[0032] The molding unit is connected to the rear of the mixing unit and is used to granulate and polish the mixed raw materials to obtain cat litter granule semi-finished products; the molding unit includes an extrusion granulator 4 and a shot blasting machine 5. The extrusion granulator 4 is connected to the discharge end of the vertical mixer 3, and the discharge end of the extrusion granulator 4 is connected to the shot blasting machine 5 through the first climbing machine 6; the combination of the extrusion granulator 4 and the shot blasting machine 3 is used to improve the shape and quality of the cat litter granules. First, the mixed raw materials are extruded into columnar particles through the extrusion granulator 4. The screw design and mold structure of the extrusion granulator 4 are After optimization, the density of the particles can be made higher, ensuring the basic shape and strength of the cat litter; the extruded columnar particles are then fed into the shot blasting machine 5, where the rotating disc and specific friction inside the shot blasting machine 5 roll the columnar particles into a nearly spherical shape, making the surface of the cat litter particles smoother and reducing dust generation. At the same time, the spherical particles have better fluidity in the cat litter box, making it more comfortable for cats to use; the produced cat litter particles have a regular shape and a smooth surface, which not only improves the appearance quality of the product, but also effectively reduces the dust content, thereby enhancing the product's performance and market competitiveness;

[0033] The drying unit is connected to the rear of the forming unit and is used to dry the semi-finished cat litter particles to obtain strip-shaped cassava cat litter; the drying unit adopts a multi-layer belt dryer 7, which is connected to the discharge end of the shot blasting machine 5 through a second climbing machine 8; the multi-layer belt dryer 7 is used to achieve efficient drying, and the formed cat litter particles are first conveyed to the multi-layer belt dryer 7 for drying. The multi-layer belt dryer 7 can uniformly dry the cat litter at low temperature by adjusting the speed and drying temperature of the conveyor belt to remove most of the moisture. This drying method can not only ensure the drying effect and make the cat litter reach a lower water content, but also improve the drying efficiency, shorten the production cycle, and at the same time reduce the impact of high-temperature and long-term drying on the performance of the cat litter.

[0034] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] It should be noted that the components mentioned in the above embodiments are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0036] The cassava cat litter produced by the above production line controls the size of cassava particles and uses particles in the diameter range of 2-3mm to simulate the feel of natural sand while ensuring that there are appropriate gaps between the cat litters. The large and small particles are scientifically matched to achieve the effect of precise matching with less sand, firmer clumps, and smaller volume. Even if urine clumps are stuck in the gaps of the cat litter box, they can be easily cleaned. At the same time, the agglomeration properties of sodium carboxymethyl starch are utilized to make the cat litter form compact clumps after absorbing urine and feces, making it easier for the owner to clean. The particles with a hexagonal microporous structure increase the specific surface area by 15% compared to ordinary round particles, increasing the contact area with urine and feces, and further improving the water absorption and deodorization efficiency.

[0037] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be understood as limiting the present invention.
