[0002] Cat litter, as a daily pet product, typically involves multiple steps in its production process, including granulation, drying, sieving, and packaging. Among these, the drying process directly affects the quality and performance of the finished cat litter.

[0003] Currently, most common cat litter drying devices use static hot air furnaces or single heat source drying methods. These devices often suffer from uneven drying, low heat energy utilization efficiency, and localized cat litter sticking to the conveyor belt, which in turn leads to high moisture content, poor cohesion, or increased pulverization of the cat litter, affecting its subsequent packaging and final use. Therefore, a drying device for the cat litter production process is proposed. Summary of the Invention

A spiral tube is fixedly connected to the outer wall of each horizontal heat pipe. The horizontal heat pipe and the spiral tube are interconnected at the contact point of the outer wall.

[0007] Each of the horizontal heating tubes is equipped with a sealing rotary joint at both ends. The horizontal heating tube and the spiral tube are integrally set above the conveyor belt of the cat litter conveyor. The sealing rotary joint is used to allow the horizontal heating tube to rotate during the conveying process, causing the spiral tube to roll and contact the surface of the conveyor belt of the cat litter conveyor.

[0008] One end of each of the multiple equally spaced horizontal heat pipes is fixedly connected to a sealing cover.

[0009] The material trough receiving plate is screwed to the bottom of the cat litter conveyor at both sides of the top.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Please see Figures 1-4 This utility model provides a technical solution: a drying device for the cat litter production process, comprising...

[0027] The drying mechanism includes a cat litter conveyor 11, which continuously conveys cat litter during the drying process. The cat litter moves inside the device via a conveyor belt. The top side of the cat litter conveyor 11 is screwed to a dryer cover 16 to form a closed drying space to prevent heat loss and improve drying efficiency.

[0028] The inner walls of the dryer cover 16 are screwed with fixing plates 162 on both sides. Between the two fixing plates 162, there are multiple horizontal heating pipes 164 arranged at equal intervals along the conveying direction. These horizontal heating pipes 164 are used to heat the cat litter, forming a heating grid structure that can cover the entire conveyor belt area and ensure that the cat litter is heated evenly.

[0029] A spiral tube 165 is fixedly connected to the outer wall of the horizontal heat pipe 164. The contact point between the outer walls of the horizontal heat pipe 164 and the spiral tube 165 is connected. The spiral tube 165 is tightly wound around the outer side of the horizontal heat pipe 164. The two achieve a heat flow connection structure at the contact point of the outer walls. That is, the spiral tube 165 and the interior of the horizontal heat pipe 164 form a heat medium flow loop, which enhances the heat transfer efficiency, extends the heat exchange path, and thus improves the drying performance.

[0030] In this embodiment, specifically: both ends of the horizontal heat pipe 164 are equipped with sealed rotary joints 163. The horizontal heat pipe 164 and the spiral pipe 165 are integrally arranged above the conveyor belt of the cat litter conveyor 11. The sealed rotary joints 163 not only ensure the closed-loop circulation of the heat medium inside the horizontal heat pipe, but also have the structural function of enabling the horizontal heat pipe 164 to achieve controllable rotation during the drying process. The spiral pipe 165 makes rolling contact with the surface of the cat litter conveyor 11, and its horizontal heat pipe 164 also rotates accordingly through the sealed rotary joints 163, achieving the following two effects:

[0031] On the one hand, during the operation of the conveyor belt of the cat litter conveyor 11, the rotation of the spiral tube 165 can slightly turn and comb the cat litter, which helps the cat litter to be heated more evenly and improves the drying effect.

[0032] On the other hand, rolling contact can also effectively prevent cat litter from sticking to the conveyor belt surface during the drying process, avoiding adhesion residue caused by high humidity or material accumulation, and improving the stability and continuity of the conveying operation.

[0033] In this embodiment, specifically: one end of a plurality of equally spaced horizontal heat pipes 164 is fixedly connected to a sealing cover 161, which is used to achieve overall heat medium supply of the horizontal heat pipes 164 through the sealing cover 161.

[0034] Example 2

[0035] A drying device for cat litter production includes a hot air hood 21 with a hot air blower 12 fixedly connected to the side away from the material trough receiving tray 22 via a pipe. The hot air blower 12 provides a continuous flow of hot air into the drying device, increasing the evaporation rate of the cat litter surface and interior. A hot air pipe 13 is fixedly connected to the outer wall of the pipe connecting the hot air blower 12 and the hot air hood 21. The hot air pipe 13 extends to the cat litter conveyor 11 and is fixedly connected to the outer wall of the sealing cover 161 to achieve synchronous heating of the heat medium by the hot air. A hot air conveying pipe 14 is fixedly connected upward to the outer wall of the hot air pipe 13 near the cat litter conveyor 11. Two hot air conveying pipes 15 are fixedly connected downward to the outer wall of the hot air conveying pipe 14. The two hot air conveying pipes 15 are respectively fixedly connected to the top of the dryer cover 16 to blow hot air evenly into the drying chamber, further improving the air convection efficiency inside the chamber and accelerating the drying process.

[0036] In this embodiment, specifically: three fans 17 are installed above the dryer cover 16 by screws. These fans 17 are used to force the internal airflow, accelerate the evaporation of moisture and achieve uniform distribution of hot air, thereby preventing uneven drying caused by local accumulation of cat litter.

[0037] In this embodiment, specifically: a material trough receiving plate 22, the top two sides of which are screwed to the bottom of the cat litter conveyor 11, is used to receive the dried cat litter conveyed at the end of the conveyor belt. A hot air hood 21 is fixedly connected to one side of the material trough receiving plate 22 so that the falling cat litter continues to be baked by hot air to prevent local moisture. The material trough receiving plate 22 is inclined relative to the hot air hood 21 so that the cat litter can slide down smoothly. Two inclined holes 24 are provided at its bottom to guide the cat litter to flow out.

[0038] In this embodiment, specifically: an arc-shaped feeding trough 23 is installed below the inclined opening 24 of the feeding trough receiving plate 22 to smoothly receive cat litter falling from the inclined opening.

[0039] In this embodiment, specifically: a bracket 10 is installed at the bottom of the cat litter conveyor 11, and the two sides of the arc-shaped discharge chute 23 are fixedly connected to the inner wall of the bracket 10 by screws. The bracket 10 fixes and maintains the structural stability of the cat litter conveyor 11 and the arc-shaped discharge chute 23.

[0040] Working principle: Cat litter raw materials are input by cat litter conveyor 11 and move forward with the conveyor belt into the drying area inside the dryer cover 16. Heat medium is introduced into the horizontal heating pipes 164 and supplied centrally through the sealing cover 161. Multiple horizontal heating pipes 164 form a heating grid structure covering the conveyor belt. The horizontal heating pipes 164 can rotate slowly with the cooperation of the sealing rotary joint 163, which drives the spiral pipe 165 fixedly connected to its outer side to rotate, forming rolling contact with the surface of the conveyor belt of the cat litter conveyor 11, thereby combing and turning the cat litter particles, making the cat litter heat more evenly, and effectively preventing the cat litter from sticking to the surface of the conveyor belt during the drying process, ensuring the continuity of material conveying.

[0041] After the hot air blower 12 starts, hot air is delivered to the hot air hood 21 through the pipeline, and then sent into the sealing cover 161 and the horizontal heat pipe 164 area through the hot air pipe 13. At the same time, the hot air pipe 13 branches off into the first hot air delivery pipe 14, and then connects to two second hot air delivery pipes 15 to introduce hot air into the upper part of the dryer cover 16, forming a multi-point hot air convection field. The fan 17 operates synchronously, forcibly driving the hot air to circulate in the drying chamber, enhancing the heat exchange efficiency and accelerating the evaporation of cat litter moisture. After being fully heated and dried by hot air, the cat litter is discharged from the tail end of the cat litter conveyor 11 and falls into the material trough receiving plate 22 located below it. It continues to receive secondary drying treatment from the hot air hood 21 to prevent the cat litter from becoming damp again. The cat litter slides on the inclined surface of the material trough receiving plate 22 to the inclined opening 24, and finally falls into the arc-shaped material discharge trough 23 installed below it, realizing the smooth discharge and subsequent collection of cat litter, thus completing the entire drying process.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
