Description

Technical Field

[0001] This invention relates to the field of mixing preparation equipment technology, specifically to a rare earth antibacterial animal cat litter preparation process and its mixing preparation equipment. Background Technology

[0002] Cat litter is an item used by owners to bury feces and urine in their cats. It is an essential item for pet cats. Cat litter has good absorbency and is usually used in conjunction with a litter box (or cat toilet). Pour an appropriate amount of cat litter into the litter box, and a trained cat will go into the litter box to relieve itself when it needs to.

[0003] To provide a good excretion environment for cats, the ability of cat litter to resist bacteria, prevent mold, deodorize, and inhibit the growth and reproduction of microorganisms is crucial. Excellent antibacterial, anti-mold, deodorizing, and antibacterial properties create clean and hygienic toilet conditions for cats, reduce the risk of pollution to the home environment, and reduce the growth and spread of bacteria and viruses in cat feces and urine, thereby avoiding harm to the health of both people and cats.

[0004] Since antibacterial, anti-mildew, deodorizing, and microbial growth inhibition are key technical requirements for cat litter, most existing cat litter products rely on adding chemical antibacterial and deodorizing agents to inhibit bacteria. However, these additives may irritate a cat's skin and respiratory tract, posing potential risks. To address this issue, rare earth components, such as rare earth antibacterial powder made from cerium oxide and zinc oxide, can be added to the cat litter. This allows the rare earth components to achieve antibacterial and deodorizing functions. The production process for animal cat litter containing rare earth components typically involves: first, crushing raw materials such as straw and rice bran, then thoroughly mixing them with bentonite, starch, binders, and superabsorbent resin, followed by the addition of rare earth antibacterial materials. After secondary stirring and standing for a period of time, the material is extruded into strip-shaped granules using an extruder. Finally, it is dried to produce cat litter. However, during the processing, because straw / rice bran is an organic fiber, bentonite is an inorganic mineral, and superabsorbent polymer is a polymer material, these components have different densities, properties, and interfacial compatibility with rare earth antibacterial materials. In other words, when the above materials are mixed, stratification may occur, resulting in uneven texture of the mixed material. At the same time, when adding rare earth antibacterial materials, the amount added is relatively small, making it difficult to ensure uniform mixing with other materials, thus leading to defects in the antibacterial performance of the finished cat litter. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a rare earth antibacterial cat litter preparation process and its mixing and preparation apparatus. This addresses the problem mentioned in the background technology that, during the mixing of cat litter components, due to the different interfacial compatibility and other properties between various materials, stratification easily occurs during the mixing and preparation process, making it difficult to ensure uniform mixing of rare earth antibacterial powder with other components, thus leading to defects in the antibacterial properties of the finished cat litter.

[0032] Based on the aforementioned scheme, the feeding section includes two feeding hoppers. The discharge end of one feeding hopper is directly connected to the input end of the primary mixing tank, and the bottom of the other feeding hopper is equipped with a crusher body, the discharge end of which is connected to the input end of the primary mixing tank.

[0033] Based on the aforementioned scheme, the mixing component includes:

[0034] A stirring drum, which is coaxially and rotatably installed inside the secondary mixing tank;

[0035] The third drive motor is fixedly installed on the secondary mixing tank, and the output end of the third drive motor is fixedly connected to the stirring drum;

[0036] The second spiral scraper is fixedly installed on the mixing drum, and the outer side of the second spiral scraper slides against the inner wall of the secondary mixing tank.

[0037] The discharge rack is fixedly installed at the output end of the secondary mixing tank;

[0038] A follow-up stirring unit is installed on the stirring drum and is used to stir the materials entering the secondary mixing tank;

[0039] A closing section is installed inside the discharge rack for accumulating materials inside the secondary mixing tank.

[0040] In order to mix rare earth antibacterial powder and other materials more evenly, the follow-up stirring unit includes:

[0046] In order to extend the mixing time of materials in the secondary mixing tank, based on the aforementioned scheme, the closing part includes a sliding closing frame, which is slidably and sealingly installed inside the discharge rack. The sliding closing frame is adapted to the output end of the secondary mixing tank, and a driving component is fixedly installed inside the discharge rack. The output end of the driving component is fixedly connected to the sliding closing frame.

[0047] A process for preparing rare earth antibacterial cat litter, using the aforementioned rare earth antibacterial cat litter mixing and preparation device, includes the following steps:

[0048] The first step is to prepare the materials. Prepare the materials used to produce cat litter, such as straw, rice bran, bentonite, starch, binder, and superabsorbent resin, as well as rare earth antibacterial powder. Prepare the above materials in a certain proportion and crush the materials that need to be crushed.

[0049] The second step is feeding. The materials that need to be crushed are first fed into the corresponding crusher body through the feed hopper. These materials are crushed. After crushing, the materials that do not need to be crushed are added to the primary mixing tank through another feed hopper. At the same time, the crushed materials are added to the primary mixing tank simultaneously through the crusher body setting, and a certain amount of rare earth antibacterial powder is poured into the storage tank.

[0050] The third step is preliminary mixing. The second drive motor is turned on, which drives the stirring shaft to rotate. The stirring shaft drives the first spiral scraper and stirring rod to rotate, thereby mixing the various materials. The materials are then fed into the mixing area inside the feeding box through the setting of the first spiral scraper.

[0051] The fourth step is to transport the rare earth antibacterial powder. Simultaneously, the conveying component is started, which continuously delivers the rare earth antibacterial powder from the storage tank into the addition area.

[0052] Fifth step, add rare earth antibacterial powder, turn on the blower, the blower blows air into the adding area through the air supply channel, and under the action of the blower, the rare earth antibacterial powder in the adding area can be sent into the mixing area through the airflow.

[0053] Step 6: Mix the rare earth antibacterial powder and turn on the first drive motor. The first drive motor drives two driven gears to rotate simultaneously through the setting of the active gear. The two driven gears drive the corresponding bulk material racks to rotate, thereby mixing the rare earth antibacterial powder and other materials that enter the mixing area of ​​the feeding box.

[0054] Step 7: Feeding. After the materials and rare earth antibacterial powder are mixed, they enter the secondary mixing tank through the feeding box.

[0055] Step 8: Mixing. Start the third drive motor. The third drive motor drives the mixing drum to rotate, which in turn drives the second spiral scraper to rotate. At the same time, the fourth drive motor synchronously drives the transmission shaft to rotate. The transmission shaft rotates in the opposite direction to the mixing drum. At this time, the transmission shaft drives several second helical gears to rotate synchronously. Through the setting of the first helical gears that correspond to and mesh with several second helical gears, the corresponding mixing frame is driven to rotate, thereby cooperating with the second spiral scraper to mix the materials in the secondary mixing tank.

[0056] Step 9: Discharge. Retract the drive unit. The drive unit moves the sliding closing frame until the sliding closing frame moves away from the feed end of the discharge frame. At this time, as the mixing drum and the second spiral scraper continue to rotate, the material can be discharged through the discharge frame and then collected.

[0057] Step 10: Extrusion. After the materials have been left to stand for a period of time, the mixed materials are put into an extruder and extruded into granules.

[0058] Step 11: Drying. These granules are sent to a microwave dryer for drying to produce the finished cat litter.

[0059] (III) Beneficial Effects

[0060] Compared with the prior art, the present invention provides a rare earth antibacterial animal cat litter preparation process and its mixing and preparation device, which has the following beneficial effects:

[0061] 1. In this invention, during the process of adding rare earth antibacterial powder, the rare earth antibacterial powder first enters the addition zone. At this time, the blower sends air to the addition zone through the air supply channel, which can send the rare earth antibacterial powder in the addition zone into the mixing zone through the airflow. With the continuous stirring of the bulk rack, and under the action of the airflow, the uniformity of the rare earth antibacterial powder mixed with other materials is improved, avoiding the uneven distribution of rare earth antibacterial powder and other components in the mixed material, improving the mixing efficiency and uniformity, thereby stabilizing the quality of cat litter.

[0062] 2. In this invention, in the secondary mixing tank, the stirring drum drives the second spiral scraper to rotate, while the fourth drive motor synchronously drives the transmission shaft to rotate in the opposite direction. At this time, the transmission shaft drives several second helical gears to rotate synchronously. Thus, through the setting of the first helical gears that correspond one-to-one with and mesh with several second helical gears, the corresponding stirring frame is driven to rotate. This, together with the second spiral scraper, thoroughly stirs the material in the secondary mixing tank from multiple angles, improves the uniformity of the material, reduces the occurrence of material stratification, and ensures the stable antibacterial properties of the finished cat litter.

[0063] 3. In this invention, the materials are first pre-mixed by the pre-mixing component, and then the rare earth antibacterial powder is mixed with the pre-mixed materials by the rare earth mixing component, thereby improving the uniformity of mixing. The mixing component further makes the rare earth antibacterial powder more evenly distributed in the materials, thereby effectively improving the quality stability of the finished cat litter.

[0075] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] Example 1, please refer to Figures 1 to 10 A rare earth antibacterial cat litter mixing and preparation device includes a frame 1, a supporting frame 2 fixedly mounted on the frame 1, a primary mixing tank 3, a secondary mixing tank 4, a rare earth mixing component, a premixing component, and a homogenizing component. The primary mixing tank 3 is fixedly mounted on the top of the frame 1, and the secondary mixing tank 4 is fixedly mounted inside the frame 1. Both the primary and secondary mixing tanks 3 and 4 are inclined, with the input end of the primary mixing tank 3 being higher than the output end. The rare earth mixing component is mounted on the supporting frame 2 and is used to add rare earth antibacterial powder to the material during the process of the material entering the secondary mixing tank 4 from the primary mixing tank 3. The rare earth mixing component includes a lower... The equipment includes a material box 5, a storage tank 6, a conveying component 7, an air supply unit, and a bulk material distribution unit. The material box 5 is fixedly installed inside the equipment frame 1. The top of the material box 5 is connected to the output end of the primary mixing tank 3, and the bottom of the material box 5 is connected to the input end of the secondary mixing tank 4. The material box 5 includes a mixing area and an addition area. The storage tank 6 is fixedly installed on the support frame 2. The conveying component 7 is installed on the support frame 2. The input end of the conveying component 7 is connected to the output end of the storage tank 6, and the output end of the conveying component 7 is connected to the addition area. The air supply unit is installed inside the equipment frame 1 and is used to deliver rare earth antibacterial powder into the mixing area when it is added. The bulk material distribution unit is installed inside the mixing area for mixing materials and rare earth antibacterial powder.

[0077] Among them, the conveying component 7 is set as a screw conveyor, such as Figure 6As shown, valves are provided at both the input and output ends of the conveying component 7. When it is necessary to send rare earth antibacterial powder into the addition area, the valves at the input and output ends of the conveying component 7 are opened, and then the screw conveyor is opened simultaneously to send the rare earth antibacterial powder in the storage tank 6 into the addition area.

[0078] Specifically, in preparing rare earth antibacterial cat litter, first prepare the materials used for cat litter production, such as straw, rice bran, bentonite, starch, binder, and superabsorbent resin, as well as rare earth antibacterial powder. Prepare these materials in a certain proportion. At this time, the prepared straw, rice bran, and other materials that need to be crushed can be crushed until they reach the required degree. Pour a certain amount of rare earth antibacterial powder into the storage tank 6, and then start mixing these materials together. At this time, pour the crushed materials and other materials into the primary mixing tank 3, and start the premixing component to mix and stir these materials. As the stirring continues, the premixed material enters the mixing zone inside the feeding box 5 under the action of the premixing component. At this time, the conveying component is started simultaneously, and the conveying component transports the rare earth antibacterial powder in the storage tank 6. The bacterial powder is continuously fed into the addition zone. Through the air supply unit, the rare earth antibacterial powder in the addition zone is sent to the mixing zone. At this time, the rare earth antibacterial powder entering the mixing zone meets with other materials that have undergone preliminary mixing. Then, the bulk material section is opened. Through the bulk material section, the rare earth antibacterial powder can be mixed with other materials that have undergone preliminary mixing. Then, it enters the secondary mixing tank 4. At this time, the materials entering the secondary mixing tank 4 have undergone preliminary mixing with the rare earth antibacterial powder. Then, the mixing component is opened to stir and mix the materials entering the secondary mixing tank 4 until they are evenly mixed. Then, the mixed materials are taken out and left to stand for a period of time. Then, the mixed materials are put into the extruder and extruded into granules (usually in the shape of round strips). Then, these granules are sent to the microwave dryer for drying treatment, and then the cat litter product is produced.

[0079] The above, such as Figures 4 to 6 As shown, the air supply unit includes a blower 8 and an air supply channel 9. The blower 8 is fixedly installed inside the equipment frame 1. One end of the air supply channel 9 is connected to the output end of the blower 8, and the other end of the air supply channel 9 is fixedly installed at the lower part of the feeding box 5. The air supply channel 9 is connected to the addition area.

[0080] Specifically, during the addition of rare earth antibacterial powder, the powder first enters the addition zone. At this time, blower 8 is turned on, and blower 8 sends air into the addition zone through air supply channel 9. Under the action of blower 8, the rare earth antibacterial powder in the addition zone is sent into the mixing zone by the airflow. At the same time, the airflow also improves the uniformity of the mixing of rare earth antibacterial powder with other materials, avoiding uneven distribution of rare earth antibacterial powder and other components in the mixed material. This improves the mixing efficiency and uniformity, thereby stabilizing the production quality of the cat litter product.

[0081] The above, such as Figure 5 , Figure 6 As shown, the bulk material section includes a bulk material rack 10 and a first drive motor 11. Two bulk material racks 10 are symmetrically and rotatably installed inside the mixing area. The first drive motor 11 is fixedly installed on the feeding box 5. A drive gear 12 is fixedly installed at the output end of the first drive motor 11. Two driven gears 13 are also rotatably installed on the feeding box 5. The driven gears 13 are coaxial with the bulk material rack 10 and fixedly connected. Both driven gears 13 mesh with the drive gear 12.

[0082] Specifically, when it is necessary to mix the rare earth antibacterial powder and other pre-mixed materials entering the mixing zone of the feeding box 5, the first drive motor 11 is turned on. The first drive motor 11 drives two driven gears 13 to rotate simultaneously through the setting of the drive gear 12. The two driven gears 13 drive the corresponding bulk material racks 10 to rotate, thereby mixing the rare earth antibacterial powder and other materials entering the mixing zone of the feeding box 5.

[0083] It is important to note that, such as Figure 6 As shown, the bulk material rack 10 consists of two coaxially arranged mounting frames and several bulk material rods fixedly installed between the two mounting frames. The bulk material rods are arranged in a circular shape with equal angles around the axis of the mounting frame. The bulk material rods on the two bulk material racks 10 have a cross-section area on one side near the center of the mixing zone. The bulk material rods on the two bulk material racks 10 in this area are staggered to improve the uniformity of mixing of materials and rare earth antibacterial powder.

[0084] like Figure 7As shown, the premixing component is installed inside the primary mixing tank 3 for preliminary mixing of materials. The premixing component includes a stirring shaft 14, a second drive motor 15, a first spiral scraper 16, stirring rods 17, and a feeding section. The stirring shaft 14 is coaxially rotatably installed inside the primary mixing tank 3. The second drive motor 15 is fixedly installed on the primary mixing tank 3, and the output end of the second drive motor 15 is fixedly connected to the stirring shaft 14. The first spiral scraper 16 is fixedly installed on the stirring shaft 14, and the outer side of the first spiral scraper 16 slides against the inner wall of the primary mixing tank 3. Several sets of stirring rods 17 are fixedly installed at equal intervals along the axis on the stirring shaft 14, and each set of stirring rods 17 has several rods. The feeding section is installed on the primary mixing tank 3 for feeding the materials to be used into the primary mixing tank 3.

[0085] Specifically, when initially mixing multiple materials, they are first fed into the primary mixing tank 3 through the feeding section. At this time, the second drive motor 15 is turned on, which drives the stirring shaft 14 to rotate. The stirring shaft 14 drives the first spiral scraper 16 and the stirring rod 17 to rotate, thereby mixing multiple materials and sending them to the feeding box 5 until they are fed into the feeding box 5.

[0086] It should be added that the stirring rod 17 is made of a flexible material, such as rubber. During the mixing process, it can not only reduce the possibility of damage, but also exert a certain impact on some clumps during the mixing process, thereby breaking up these clumps and improving the uniformity of mixing multiple materials.

[0087] The above, such as Figure 7 As shown, the feeding section includes two feeding hoppers 18. The discharge end of one feeding hopper 18 is directly connected to the input end of the primary mixing tank 3. The bottom of the other feeding hopper 18 is equipped with a crusher body 19, and the discharge end of the crusher body 19 is connected to the input end of the primary mixing tank 3.

[0088] Specifically, before adding multiple materials to the primary mixing tank 3, the materials are initially divided into those that need to be crushed and those that do not. The materials that need to be crushed include straw and rice bran, while the materials that do not need to be crushed include bentonite, starch, binders, and superabsorbent resins. At this point, the materials that need to be crushed are crushed first. Then, the crushed straw, rice bran, and other materials that do not need to be crushed are pre-mixed outside the equipment and then fed into the primary mixing tank 3 through the feed hopper 18. Alternatively, the materials that need to be crushed can be fed into the corresponding crusher body 19 through the feed hopper 18 first and crushed. After crushing, the materials that do not need to be crushed are added to the primary mixing tank 3 through another feed hopper 18. At the same time, the crushed materials are added to the primary mixing tank 3 simultaneously through the setting of the crusher body 19.

[0089] It should be noted that when adding materials through the feed hopper 18, in order to improve the uniformity of mixing, the materials can be pre-mixed together after determining the proportion of each material before pouring them into the primary mixing tank 3 (materials that need to be crushed, such as straw and rice bran, need to be crushed before mixing), and then fed into the primary mixing tank 3 through the feed hopper 18.

[0090] When there are no materials that need to be crushed, such as straw and rice bran, these materials can be poured into the crusher body 19 through the feed hopper 18 first. Then, other materials are mixed and poured into the primary mixing tank 3 through another feed hopper 18. At the same time, the crushed materials are poured into the primary mixing tank 3 through the crusher. At this time, attention should be paid to the speed at which other materials are poured into the primary mixing tank 3. That is to say, the two must start pouring at the same time and finish pouring at the same time to end the pouring. During the pouring process, it is necessary to ensure the uniformity of pouring to improve the uniformity of the initial mixing.

[0091] like Figures 8 to 10 As shown, the mixing assembly is installed inside the secondary mixing tank 4 for mixing materials. The mixing assembly includes a stirring drum 20, a third drive motor 21, a second spiral scraper 22, a discharge rack 23, a follow-up stirring part, and a closing part. The stirring drum 20 is coaxially and rotatably installed inside the secondary mixing tank 4. The third drive motor 21 is fixedly installed on the secondary mixing tank 4, and its output end is fixedly connected to the stirring drum 20. The second spiral scraper 22 is fixedly installed on the stirring drum 20, and its outer side slides against the inner wall of the secondary mixing tank 4. The discharge rack 23 is fixedly installed at the output end of the secondary mixing tank 4. The follow-up stirring part is installed on the stirring drum 20 for stirring the materials entering the secondary mixing tank 4. The closing part is installed inside the discharge rack 23 for accumulating the materials inside the secondary mixing tank 4.

[0092] Specifically, after the materials have been initially mixed and rare earth antibacterial powder has been added, the materials need to be further stirred to make them more uniform. At this time, the third drive motor 21 is started, which drives the mixing drum 20 to rotate. The mixing drum 20 drives the second spiral scraper 22 to rotate. At the same time, the follow-up stirring part mixes and stirs the materials in the secondary mixing tank 4 in sync with the rotation of the mixing drum 20. At this time, the closing part is in the working position. After stirring the materials for a period of time (this time needs to be comprehensively considered based on factors such as the total mass of all materials, the state of the materials, and the degree of dryness, and is generally about 20 minutes), the closing part can be opened, and the uniformly stirred materials can be discharged through the discharge rack 23.

[0093] The above, such as Figure 9 , Figure 10As shown, the follow-up stirring unit includes a drive shaft 24, a fourth drive motor 25, a mounting base 26, a first helical gear 30, and a second helical gear 31. The drive shaft 24 is coaxially rotatably mounted inside the stirring drum 20. The fourth drive motor 25 is fixedly mounted on the secondary mixing tank 4, and the output end of the fourth drive motor 25 is fixedly connected to the drive shaft 24. Two sets of mounting bases 26 are symmetrically arranged on the stirring drum 20, and several mounting bases 26 are arranged at equal distances. Each mounting base 26 is sealed and rotatably mounted with a stirring frame 27. The stirring frame 27 does not contact the second spiral scraper 22. A first helical gear 30 is coaxially fixedly mounted at the bottom of each stirring frame 27. Several second helical gears 31 are fixedly mounted at equal distances on the drive shaft 24. Several first helical gears 30 and several second helical gears 31 correspond one-to-one and mesh.

[0094] Specifically, when the third drive motor 21 drives the mixing drum 20 to rotate, the fourth drive motor 25 synchronously drives the transmission shaft 24 to rotate. The transmission shaft 24 rotates in the opposite direction to the mixing drum 20. At this time, the transmission shaft 24 drives several second helical gears 31 to rotate synchronously. Thus, through the setting of the first helical gears 30 that correspond one-to-one with and mesh with several second helical gears 31, the corresponding mixing frame 27 is driven to rotate. This, in conjunction with the second spiral scraper 22, fully mixes the material in the secondary mixing tank 4, improves the uniformity of the material, and reduces the occurrence of material stratification.

[0095] It should be added that, such as Figure 9 , Figure 10 As shown, the stirring frame 27 is configured in two parts: one part is the connecting end that is sealed and rotatably connected to the mounting base 26, and the other part is the working end for stirring the material. The working end is provided with several flexible rods for stirring in a circumferential shape at equal angles. These flexible rods are made of rubber or other flexible materials, and the free ends of the flexible rods abut against the inner wall of the secondary mixing tank 4, which not only improves the mixing efficiency but also reduces the possibility of material adhering to the inner wall of the secondary mixing tank 4.

[0096] The above, such as Figure 8 As shown, the closing part includes a sliding closing frame 28, which is slidably and sealingly installed inside the discharge rack 23. The sliding closing frame 28 is adapted to the output end of the secondary mixing tank 4. A driving component 29 is fixedly installed inside the discharge rack 23. The output end of the driving component 29 is fixedly connected to the sliding closing frame 28. The driving component 29 is preferably in the form of an electric cylinder.

[0097] Specifically, when it is necessary to discharge the material after mixing, the drive component 29 is retracted, and the drive component 29 drives the sliding closing frame 28 to move until the sliding closing frame 28 moves away from the feed end of the discharge frame 23. At this time, as the mixing drum 20 and the second spiral scraper 22 continue to rotate, the material can be discharged through the discharge frame 23, and then the material can be collected.

[0098] The working principle or usage process of this application is as follows:

[0099] When preparing rare earth antibacterial cat litter, first prepare the materials used for cat litter production, such as straw, rice bran, bentonite, starch, binder, and superabsorbent polymer (SAP), as well as rare earth antibacterial powder. Prepare the above materials in a certain proportion. First, divide the various materials into materials that need to be crushed and materials that do not need to be crushed. The materials that need to be crushed include straw and rice bran, while the materials that do not need to be crushed include bentonite, starch, binder, and SAP. At this time, crush the materials that need to be crushed first. Then, after the crushed straw, rice bran, and other materials that do not need to be crushed are pre-mixed outside the equipment, all of them are fed into the primary mixing tank 3 through the feed hopper 18. Alternatively, the materials that need to be crushed can be fed into the corresponding crusher body 19 through the feed hopper 18 first to crush these materials. After crushing, add the materials that do not need to be crushed into the primary mixing tank 3 through another feed hopper 18. At the same time, through the setting of the crusher body 19, the crushed materials are added to the primary mixing tank 3 simultaneously, and a certain amount of rare earth antibacterial powder is poured into the storage tank 6.

[0100] After feeding multiple materials into the primary mixing tank 3, the second drive motor 15 is turned on. The second drive motor 15 drives the stirring shaft 14 to rotate, and the stirring shaft 14 drives the first spiral scraper 16 and the stirring rod 17 to rotate, thereby mixing multiple materials. As the mixing continues, the materials are sent to the position of the feeding box 5 through the setting of the first spiral scraper 16 until they are sent into the mixing area inside the feeding box 5.

[0101] Then, the conveying assembly is started synchronously, continuously feeding the rare earth antibacterial powder from the storage tank 6 into the addition area. At this time, the blower 8 is turned on, and the blower 8 blows air into the addition area through the air supply channel 9. Under the action of the blower 8, the rare earth antibacterial powder in the addition area is sent into the mixing area by the airflow. At this time, the rare earth antibacterial powder entering the mixing area meets other materials that have been initially mixed. At the same time, the first drive motor 11 is turned on. The first drive motor 11 drives two driven gears 13 to rotate through the setting of the drive gear 12. The two driven gears 13 drive the corresponding bulk material racks 10 to rotate, thereby mixing the rare earth antibacterial powder and other materials that have entered the mixing area of ​​the feeding box 5. At the same time, under the action of the airflow, the uniformity of the mixing of rare earth antibacterial powder and materials is improved, avoiding uneven distribution of rare earth antibacterial powder and other components after mixing. This improves the mixing efficiency and uniformity, thereby stabilizing the production quality of the cat litter product. After passing through the feeding box 5, the materials and rare earth antibacterial powder enter the secondary mixing tank 4.

[0102] The material entering the secondary mixing tank 4 has already undergone preliminary mixing with the rare earth antibacterial powder. At this time, the third drive motor 21 is started, which drives the stirring drum 20 to rotate. The stirring drum 20 drives the second spiral scraper 22 to rotate. When the third drive motor 21 drives the stirring drum 20 to rotate, the fourth drive motor 25 synchronously drives the transmission shaft 24 to rotate. The transmission shaft 24 rotates in the opposite direction to the stirring drum 20. At this time, the transmission shaft 24 drives several second helical gears 31 to rotate synchronously. Thus, through the setting of the first helical gears 30 that correspond one-to-one with and mesh with several second helical gears 31, the corresponding stirring frame 27 is driven to rotate, thereby cooperating with the second spiral scraper 22 to fully stir the material in the secondary mixing tank 4, improve the uniformity of the material, and reduce the occurrence of material stratification. At this time, the sliding closing frame 28 is in the working position.

[0103] After the materials are mixed, when it is necessary to discharge the mixed materials, the drive component 29 is retracted. The drive component 29 drives the sliding closing frame 28 to move until the sliding closing frame 28 moves away from the feed end of the discharge frame 23. At this time, as the mixing drum 20 and the second spiral scraper 22 continue to rotate, the materials can be discharged through the discharge frame 23. Then the materials are collected, and after the materials stand for a period of time, the mixed materials are put into an extruder to be extruded into granules (usually in the shape of round strips). Then these granules are sent to a microwave dryer for drying treatment, and then the cat litter product can be made.

[0104] Example 2: Based on a rare earth antibacterial animal cat litter mixing and preparation device, this example 2 also proposes a rare earth antibacterial animal cat litter preparation process, including the following steps:

[0105] The first step is to prepare the materials. Prepare the materials used to produce cat litter, such as straw, rice bran, bentonite, starch, binder, and superabsorbent polymer, as well as rare earth antibacterial powder. Prepare the above materials in a certain proportion and crush the materials that need to be crushed (straw and rice bran).

[0106] The second step is feeding. The materials that need to be crushed are first fed into the corresponding crusher body 19 through the feed hopper 18. After crushing, the materials that do not need to be crushed are added to the primary mixing tank 3 through another feed hopper 18. At the same time, the crushed materials are added to the primary mixing tank 3 synchronously through the setting of the crusher body 19, and a certain amount of rare earth antibacterial powder is poured into the storage tank 6.

[0107] The third step is preliminary mixing. The second drive motor 15 is turned on, which drives the stirring shaft 14 to rotate. The stirring shaft 14 drives the first spiral scraper 16 and the stirring rod 17 to rotate, thereby mixing the various materials. As the mixing continues, the materials are sent to the position of the feeding box 5 through the setting of the first spiral scraper 16 until they are sent into the mixing area inside the feeding box 5.

[0108] The fourth step is to transport the rare earth antibacterial powder. Simultaneously, the conveying component is started, which continuously delivers the rare earth antibacterial powder from the storage tank 6 into the addition area.

[0109] Fifth step, add rare earth antibacterial powder and turn on blower 8. Blower 8 blows air into the adding area through air supply channel 9. Under the action of blower 8, the rare earth antibacterial powder in the adding area can be sent into the mixing area by airflow. At this time, the rare earth antibacterial powder entering the mixing area meets other materials that have been initially mixed.

[0110] Step 6: Mixing rare earth antibacterial powder. Turn on the first drive motor 11. The first drive motor 11 drives two driven gears 13 to rotate simultaneously through the setting of the drive gear 12. The two driven gears 13 drive the corresponding bulk material racks 10 to rotate, thereby mixing the rare earth antibacterial powder and other materials that enter the mixing area of ​​the feeding box 5. At the same time, under the action of airflow, the uniformity of mixing of rare earth antibacterial powder and materials is improved, avoiding uneven distribution of rare earth antibacterial powder and other components after mixing, thus improving the mixing efficiency and uniformity.

[0111] Step 7: Feeding. After the materials and rare earth antibacterial powder are mixed, they enter the secondary mixing tank 4 through the feeding box 5.

[0112] Step 8: Mixing. Start the third drive motor 21. The third drive motor 21 drives the mixing drum 20 to rotate. The mixing drum 20 drives the second spiral scraper 22 to rotate. When the third drive motor 21 drives the mixing drum 20 to rotate, the fourth drive motor 25 synchronously drives the transmission shaft 24 to rotate. The transmission shaft 24 rotates in the opposite direction to the mixing drum 20. At this time, the transmission shaft 24 drives several second helical gears 31 to rotate synchronously. Thus, through the setting of the first helical gears 30 that correspond one-to-one with and mesh with several second helical gears 31, the corresponding stirring frame 27 is driven to rotate. This, together with the second spiral scraper 22, fully mixes the material in the secondary mixing tank 4, improves the uniformity of the material, and reduces the occurrence of material stratification.

[0113] Step 9: Discharge the material and retract the drive unit 29. The drive unit 29 drives the sliding closing frame 28 to move until the sliding closing frame 28 moves away from the feed end of the discharge frame 23. At this time, as the mixing drum 20 and the second spiral scraper 22 continue to rotate, the material can be discharged through the discharge frame 23 and then collected.

[0114] Step 10: Extrusion. After the materials have been left to stand for a period of time, the mixed materials are put into an extruder and extruded into granules.

[0115] Step 11: Drying. These granules are then sent to a microwave dryer for drying to produce the finished cat litter.
