Description

Technical Field

[0001] This utility model relates to the technical field of cat litter pelletizing machines, specifically an environmentally friendly cat litter pelletizing machine. Background Technology

[0002] A cat litter pelletizing machine is a piece of equipment used to produce cat litter pellets. It can process different raw materials such as pine sawdust, tofu residue, and bentonite into cat litter pellets. The production process of cat litter includes raw material preparation, grinding, mixing, granulation, drying, screening, and packaging.

[0003] However, in the current technology of cat litter granulation molding machines, when the raw materials are crushed and ground in the early stage of use, hard particles such as stones may be mixed in during the storage or transportation of the raw materials. These particles and impurities will damage the crushing parts during the grinding process due to their hardness, and the impurities will affect the crushing effect of the raw materials, resulting in a reduction in the crushing quality. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly cat litter granulation machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An environmentally friendly cat litter pelletizing machine includes a crushing frame, an installation frame at the bottom of the crushing frame, and an impurity removal component inside the installation frame for removing impurities during the crushing of raw materials. The impurity removal component includes an air pump installed on the outer wall of the installation frame. A cavity is provided inside the installation frame, and an impurity box is provided on the inner wall of the cavity.

[0007] The top of the mounting frame is provided with multiple slots, each slot has a baffle at one end and a control valve at the other end, and each slot has a mesh and a spring inside.

[0008] Each of the multiple holes and slots has a through groove on one side, and a one-way valve is provided at one end of the through groove.

[0009] As a preferred embodiment of this utility model, the mounting frame is located at the bottom of the crushing frame and is embedded inside the crushing frame and communicates with the inside of the crushing frame. The crushing frame is equipped with spiral blades and its bottom is connected to the mixing chamber of the cat litter pellet machine.

[0010] As a preferred embodiment of this utility model, the air pump is connected to the inner wall of the mounting frame by bolts, and gas is injected into the cavity by the air pump. The cavity of the mounting frame is normally in a closed state, and the injected air increases the air pressure in the cavity.

[0011] As a preferred embodiment of this utility model, the plurality of holes and slots are arranged in an array on the top of the mounting frame and communicate with the inside of the crushing frame. The baffle is located at one end of the hole and slot near the crushing frame and rotates with the inner wall of the hole and slot via a spring shaft.

[0012] As a preferred embodiment of this utility model, the mesh is located inside the slot and is slidably connected to the inner wall of the slot. The mesh has a hollow structure and an infrared sensor is installed on the top. The infrared sensor is electrically connected to the control valve. Both ends of the spring are welded to the mesh and the inner wall of the slot respectively. One end of the slot communicates with the cavity and is isolated by the control valve.

[0013] As a preferred embodiment of this utility model, the two ends of the through groove are distributed and communicate with the hole groove and the cavity, and the end near the cavity is separated by a one-way valve. The through groove is located below the mesh in the normal state at the end of the hole groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In response to the problems mentioned in the background art, this application adopts a purification component. By installing a frame at the bottom of the box for crushing raw materials, the raw materials will fall onto the frame by gravity when they are away from the crushing process. Since cat litter raw materials are mostly lightweight materials such as wood chips, tofu residue, and bentonite, they will be blocked by the baffles in the slots to prevent them from falling. However, pebbles and other particles are denser and heavier, so they will pass through the baffles and fall into the slots, pressing down on the mesh in the slots. As the mesh shrinks to the through-slot area, it tilts, causing impurities to fall off and be captured and collected by the impurity box. This achieves the removal of particulate impurities from the raw materials, preventing them from affecting the crushing of the raw materials and ensuring the stability of the crushing process.

[0015] This invention uses the gravity difference between raw materials and particulate impurities for screening, capturing and collecting particulate impurities, reducing their impact with the crushing blades, ensuring the safety and stability of raw material crushing, and improving the quality of raw material crushing.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Example

[0021] Please see Figure 1-3 This utility model provides a technical solution: an environmentally friendly cat litter granulation molding machine, including a crushing frame 1, a mounting frame 2 at the bottom of the crushing frame 1, and a purification component inside the mounting frame 2 for removing impurities during the crushing of raw materials. The purification component includes an air pump 3 installed on the outer wall of the mounting frame 2. A cavity 4 is installed inside the mounting frame 2, and an impurity box 401 is installed on the inner wall of the cavity 4. The air pump 3 can inject gas into the cavity 4, thereby increasing the air pressure inside the cavity 4. When the control valve 702 is opened, the air pressure can be injected into the slot 5, which can blow the raw materials scattered in the slot 5 through the baffle 6 back into the crushing frame 1. Air can be injected into the crushing frame 1 during the crushing process, so that the raw materials are blown up and crushed in conjunction with the spiral blades. The impurity box 401 inside the cavity 4 can capture and collect the particulate impurities when they fall into the cavity 4, which facilitates the centralized processing of the separated particulate impurities.

[0022] The top of the mounting frame 2 is provided with multiple slots 5, the diameter of which corresponds to the size of conventional particulate impurities, and they are exposed inside the crushing frame 1. During the rotation and crushing of the raw material, the heavier particulate impurities will fall to the bottom and into the slots 5 of the mounting frame 2. The weight of the particulate impurities will push the baffle 6 down and open it, allowing the impurities to fall into the slots 5. (At the same time, cat litter particles are separated from lighter materials such as pine sawdust, tofu residue, and bentonite, which are isolated by the baffle 6 due to their lightness, thus achieving screening.) Each of the multiple slots 5 is provided with a baffle 6 at one end and a control valve 702 at the other end. The control valve 702 is used to control the connection between the slots 5 and the cavity 4. Each part is equipped with a strainer 7 and a spring 701. The spring 701 is used to support the strainer 7. When impurities or raw materials fall into the slot 5, they will be caught by the strainer 7. At the same time, the weight of the particles and impurities will cause the strainer 7 to slide downward and contract, thereby exposing the through slot 8 on one side. Furthermore, the strainer 7 will tilt when it contracts to the area of ​​the through slot 8 through the protrusion in the slot 5, causing the impurities in the strainer 7 to slide into the through slot 8 on one side. Conversely, if raw materials fall onto the strainer 7 and remain on the strainer 7 for a long time, they will be detected by the infrared sensor installed on the top and a signal will be sent. The PLC controller will control the control valve 702 to open, so that the air pressure in the cavity 4 is injected into the slot 5, which can blow the raw materials on the strainer 7 through the baffle 6 and back into the crushing frame 1.

[0023] Each of the multiple slots 5 has a through slot 8 on one side. A one-way valve 801 is provided at one end of the through slot 8. The one-way valve 801 at one end of the through slot 8 can only rotate in the direction of the cavity 4. Thus, when particulate impurities enter the through slot 8, they can enter the cavity 4 through the one-way valve 801 and be collected by their own weight.

[0024] In this embodiment, all electrical components are controlled by a conventional controller.

[0025] For an example, please refer to... Figure 1-3 The mounting frame 2 is located at the bottom of the crushing frame 1 and is embedded inside the crushing frame 1, communicating with the interior of the crushing frame 1. The crushing frame 1 is equipped with spiral blades, and its bottom is connected to the mixing chamber of the cat litter pellet machine. The air pump 3 is connected to the inner wall of the mounting frame 2 via bolts, and injects gas into the cavity 4. The cavity 4 of the mounting frame 2 is normally closed; injecting air increases the air pressure inside the cavity 4. Multiple slots 5 are arrayed on the top of the mounting frame 2 and communicate with the interior of the crushing frame 1. The baffle 6 is located at the end of the slot 5 near the crushing frame 1 and is connected to the cavity 4 via a spring shaft. Rotating with the inner wall of the slot 5, the mesh 7 is located inside the slot 5 and is slidably connected to the inner wall of the slot 5. The mesh 7 has a hollow structure and an infrared sensor is installed on the top. The infrared sensor is electrically connected to the control valve 702. Both ends of the spring 701 are welded to the mesh 7 and the inner wall of the slot 5 respectively. One end of the slot 5 communicates with the cavity 4 and is isolated by the control valve 702. The two ends of the through groove 8 are distributed and communicate with the slot 5 and the cavity 4. The end near the cavity 4 is separated by a one-way valve 801. The through groove 8 is located below the mesh 7 in the normal state. In operation, the raw materials, after initial manual screening and impurity removal, are first placed into the crushing frame 1 and crushed by spiral blades. During the crushing process, airflow causes the raw materials to scatter within the crushing frame 1. Heavier particles fall to the bottom due to their own weight and land in the slot 5 area at the top of the mounting frame 2. The particles, due to their own weight, press down on the baffle 6, causing it to rotate and open, and fall onto the strainer 7 in the slot 5. At the same time, the particles, due to their own weight, continue to press down on the strainer 7, causing it to slide downwards and shrink into the through slot 8 area within the slot 5. Furthermore, the protrusions on the inner wall of the slot 5 allow it to tilt to one side when shrinking to the through slot 8 area. The tilt angle causes the impurities to roll into the through slot 8 on one side and pass through the one-way valve 801 to fall into the impurity box 401 in the cavity 4 for collection. The crushed raw materials fall through the opening at the bottom of one end of the crushing frame 1 into the mixing chamber below for mixing, and then undergo granulation, drying, and packaging steps for production.

[0026] The working process of this utility model is as follows: First, the raw materials, after initial manual screening and impurity removal, are placed into the crushing frame 1 and crushed by spiral blades. During the crushing process, airflow causes the raw materials to scatter within the crushing frame 1. Heavier particles fall to the bottom due to their own weight and land in the slot 5 area at the top of the mounting frame 2. The particles, due to their own weight, press down on the baffle 6, causing it to rotate and open, and fall onto the strainer 7 in the slot 5. Simultaneously, the weight of the particles continues to press down on the strainer 7, causing it to slide downwards and shrink into the through-slot 8 area within the slot 5. The protrusions on the inner wall of the slot 5 allow it to tilt to one side when shrinking to the through-slot 8 area. This tilting angle causes the impurities to roll into the through-slot 8 and pass through the one-way valve 801, falling into the impurity box 401 in the cavity 4 for collection. The crushed raw materials fall through the opening at the bottom of one end of the crushing frame 1 into the mixing chamber below for mixing, and then undergo granulation, drying, and packaging steps for production. This invention uses the gravity difference between raw materials and particulate impurities for screening, capturing and collecting particulate impurities, reducing their impact with the crushing blades, ensuring the safety and stability of raw material crushing, and improving the quality of raw material crushing.

[0027] 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.
