Description

Technical Field

[0001] The present invention belongs to the technology of cat litter production, and specifically relates to an integrated device for granulating, drying and screening plant fiber source cat litter. Background Art

[0002] Cat litter is a pet product used by pet cats to cover feces and urine. Among them, plant fiber source cat litter, as a kind of organic cat litter, has the advantages of being pollution-free and not afraid of being accidentally eaten. In order to mass-produce plant fiber source cat litter, an integrated preparation device is required.

[0003] The following problems exist in the existing cat litter preparation equipment:

[0004] 1. When granulating cat litter, granulation, drying and screening need to be completed in sections by multiple devices. The multiple transfers of materials result in low efficiency, high energy consumption and high particle breakage rate;

[0005] 2. Most use roll granulation. However, roll granulation generally runs along the feeding direction. But when running along, only relying on extrusion easily leads to uneven distribution in the raw materials, there are pores or density gradients inside the particles. At the same time, the fine particles in the raw materials will accelerate the wear of the roll surface under the action of extrusion force. The raw materials in the middle between the two rolls are under long-term force, which easily causes the weakening of fluidity in the upper and middle parts and caking; High humidity or viscous materials are easy to adhere to the roll surface and need to be cleaned frequently by stopping the machine;

[0006] 3. The existing drying has high energy consumption and is uneven, and at the same time, dust will escape during drying, polluting the environment. Summary of the Invention

[0007] In order to solve the above technical problems, the inventor has obtained the technical solution of the present invention through practice and summary. The present invention adopts the following technical solution:

[0008] An integrated device for granulating, drying and screening plant fiber source cat litter, comprising:

[0009] A granulation component, the granulation component includes a granulation box, two groups of roll components are installed inside the granulation box, and a reduction motor is installed outside and drives the roll components to rotate. Each group of roll components includes a male roll and a female roll. Granulation protrusions are arranged on the surface of the male roll, and granulation grooves are arranged on the female roll. The positions of the granulation grooves and the granulation protrusions correspond to each other. The movement directions of the female rolls of the two groups of roll components are opposite and in contact with each other. A material guiding hopper is arranged at the bottom of the granulation box;

[0010] Drying component: The feeding port of the drying box is connected to the guiding hopper. Inside the drying box, an air inlet coil, an electric heating structure, a grid plate, a guiding air cylinder, and a material receiving cylinder are installed. The air sent by the air inlet coil is heated by the electric heating structure to form hot air flow, which undergoes hot air drying treatment on the particles on the grid plate. A guiding material cylinder is arranged on the outer side of the top of the guiding air cylinder, and the top size of the guiding material cylinder is smaller than the bottom size. The material receiving cylinder is arranged inside the drying box and on the outer side of the guiding air cylinder, and the top size of the material receiving cylinder is larger than the bottom size. A blanking port is arranged at the top of the material receiving cylinder, and a material receiving groove is formed between the outer side of the material receiving cylinder and the drying box. The material receiving groove is connected to the screening box through a pipeline, and a cyclone separator is externally connected to the top of the drying box;

[0011] Screening box: A screening plate is installed on the screening box. A rotating shaft is rotatably installed in the middle of the screening plate, a shoveling plate is installed on the rotating shaft, and a screening motor is installed at the bottom of the screening plate.

[0012] In a further improved solution, two symmetrically distributed scraping plates are installed inside the granulating box. The scraping plates are attached to the outer side of the mother roller. Two connecting rods are installed between the two scraping plates. Two ear plates and a motor are installed below the two connecting rods. A rotating lead screw and guide rods located on both sides of the lead screw are installed on the two ear plates. The output end of the motor is connected to the lead screw, a moving block is installed on the lead screw, the moving block is slidably matched with the guide rods, and a bar is installed at the lower part of the moving block.

[0013] In a further improved solution, an elastic capsule piece is embedded at the notch of the granulating groove, and a certain gap is reserved between the elastic capsule piece and the inside of the granulating groove.

[0014] In a further improved solution, the shoveling plate is arranged obliquely downward. The bottom of the shoveling plate contacts the surface of the screening plate, and a receiving mesh plate is installed at the top of the shoveling plate. The receiving mesh plate is arranged obliquely downward, and the included angle between the receiving mesh plate and the screening plate is larger than the included angle between the shoveling plate and the screening plate. A receiving frame is installed at the top of the receiving mesh plate. The top of the receiving frame is open towards the rotating direction and is also open towards the side of the screening box. A side opening is arranged on the side of the screening box, and a receiving box is installed outside the screening box. The receiving box is connected to the side opening.

[0015] In a further improved solution, a material spreading shaft is installed at the feeding port of the screening box through a bearing. Material spreading pieces are distributed on the material spreading shaft, and a material spreading motor is installed outside the screening box. The material spreading motor is connected to one end of the material spreading shaft.

[0016] In a further improved solution, a pushing plate is arranged between the bottom of the material receiving cylinder and the drying box, and a cylinder is installed on the back of the pushing plate.

[0017] In a further improved solution, a restraint plate is arranged inside the drying box. Side plates are distributed on the lower side of the restraint plate. A bottom plate is installed on the outer side of the bottom of the side plates. A spring member is connected between the bottom plate and the restraint plate. A filter plate is installed on the top of the side plates. Mesh holes are distributed on both the side plates and the filter plate.

[0018] In a further improved solution, the material receiving cylinder includes an upper cylinder and a lower cylinder. The upper cylinder and the lower cylinder are connected by a connecting member. A rotating member is rotatably installed between the upper cylinder and the lower cylinder. A rotating motor is installed on the side of the lower cylinder. The rotating motor drives the rotating member to rotate through a gear. A spreading plate is installed on the rotating member.

[0019] A processing technology for plant fiber source cat litter is as follows:

[0020] Step 1, spreading

[0021] The cat litter raw materials enter the position between two scraping plates in the granulating box. The motor drives the lead screw to rotate, driving the moving block to reciprocate. The bar strips spread the cat litter raw materials along the axial direction of the pair of rollers assembly;

[0022] Step 2, granulating

[0023] The reduction motor drives the male roller and the female roller to rotate. The two female rollers rotate against the feeding direction. The scraping plates level the raw materials in the granulating groove. The granulating protrusions on the male roller shape the raw materials in the granulating groove. After shaping, the elastic capsule pieces automatically drop the particles, obtaining cat litter particles;

[0024] Step 3, drying

[0025] The cat litter particles enter between the air guiding cylinder and the material receiving cylinder in the drying box from the feeding port. The rotating member and the spreading plate spread the cat litter particles evenly. The air cylinder drives the pushing plate to send the cat litter particle material above the air inlet coil. The cat litter particles are continuously sent above the air inlet coil. The air inlet coil sends air into the drying box. The air forms a hot air flow through the electric heating structure. The hot air flow dries the cat litter particles passing through the grid plate. The cat litter particles that meet the humidity requirements will be sent to the top by the hot air, touch the filter plate, and then disperse around. After dispersing, they lose the upward pushing force and then gradually fall, passing through the material dropping port and entering the receiving trough;

[0026] The hot air flow brings the powder during the drying process into the cyclone separator;

[0027] Step 4, screening

[0028] The dried particles in the receiving trough enter the screening box through a pipeline. The spreading motor drives the spreading shaft and the spreading pieces to rotate. The dried particles are scattered and fall on the screening plate. The screening motor drives the shoveling plate to rotate and turn the particles up at the same time. The receiving mesh plate drops the particles that do not meet the screening particle requirements to the bottom of the screening box;

[0029] Particles that meet the screening particle requirements will not pass through the receiving mesh plate, enter the interior through the material receiving frame, and finally enter the material receiving box. After cooling, finished cat litter particles are obtained; particles that do not meet the screening particle requirements pass through the receiving mesh plate and fall back onto the screening plate, and then fall to the bottom of the screening box.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. During granulation of the present invention, two master rollers are symmetrically distributed and both reverse to the feeding direction, which can break the agglomerated structure in the raw materials. The raw materials will automatically enter the granulation tank, and the granulation bumps cooperate with the granulation tank to achieve granulation. However, against the feeding direction, it is easy to cause too much raw material in the granulation tank, resulting in poor consistency of the particle density. The scraper plate can clean the excess raw material, ensuring the consistency of the particle density; the guide hopper guides the raw materials into the guide cylinder and the receiving cylinder in the drying oven. The air inlet coil box sends air into the drying oven, and the air is heated by the electric heating structure to form a hot air flow. The hot air flow dries the particles on the grid plate. When the particles are dried to a certain humidity that meets the requirements, the particles will be blown upward by the hot air flow. After being blown upward, the particles travel upward along the air guide cylinder. When passing through the air guide cylinder, due to the loss of the pushing force of the hot air flow, they will disperse and fall in all directions. After falling, they are received by the guide cylinder and guided outward. The particles will be sent into the blanking port and enter the receiving groove. The particles in the receiving groove enter the screening box, are screened by the screening plate, and then screened by the receiving mesh plate while the screening motor drives the shovel plate to rotate. After screening, the particles can obtain finished cat litter particles after cooling.

[0032] 2. When granulating, the present invention drives the lead screw to rotate through the motor, and the reciprocating movement of the moving block drives the bar to move, spreading the raw materials between the two scraper plates. Since the two master rollers rotate against the feeding direction, the rotation of the master rollers can form a dynamic flow of the raw materials between the two scraper plates, avoiding agglomeration.

[0033] 3. When granulating, the granulation bumps cooperate with the granulation tank. The granulation tank is embedded with elastic capsule pieces. Since the granulation bumps form the raw materials in the granulation tank, the elastic capsule pieces can be squeezed and deformed during forming. After forming, they can automatically fall off by using the recovery of elastic deformation.

[0034] 4. When drying, the present invention drives the pushing plate to move through the cylinder, pushing the particles between the air guide cylinder and the receiving cylinder above the air inlet coil for efficient drying treatment.

[0035] 5. The present invention installs a rotating part on the receiving cylinder. The rotating motor drives the rotating part to rotate, and the spreading plate on the rotating part spreads the particles between the receiving cylinder and the air guide cylinder, facilitating to avoid easy accumulation.

[0050] Embodiment 1

[0051] As Figure 1 and Figure 2 、 Figure 5 shown, a plant fiber source cat litter granulation, drying and screening integrated device includes:

[0052] Granulation assembly. The granulation assembly includes a granulation box 10. Inside the granulation box 10, two sets of counter-roll assemblies are installed, and a reduction motor 11 is installed on the outside to drive the counter-roll assemblies to rotate. Each set of counter-roll assemblies includes a male roll 12 and a female roll 13. Granulation protrusions 121 are provided on the surface of the male roll 12, and granulation grooves 131 are provided on the female roll 13. The positions of the granulation grooves 131 and the granulation protrusions 121 correspond to each other. The female rolls 13 of the two sets of counter-roll assemblies move in opposite directions and are in contact with each other. Two symmetrically distributed scraping plates 14 are installed inside the granulation box 10. The scraping plates 14 are attached to the outside of the female roll 13. A material guiding hopper 15 is provided at the bottom of the granulation box 10;

[0053] Drying assembly. The drying assembly includes a drying box 20. The feed inlet of the drying box 20 is connected to the material guiding hopper 15. Inside the drying box 20, an air inlet coil 21, an electric heating structure 22, a grid plate 23, an air guiding cylinder 24, and a material receiving cylinder 25 are installed. The air sent by the air inlet coil 21 is heated by the electric heating structure 22 to form a hot air stream, and the particles on it are dried by hot air through the grid plate 23. A material guiding cylinder is provided on the outside of the top of the air guiding cylinder 24. The top size of the material guiding cylinder is smaller than the bottom size. The material receiving cylinder 25 is arranged inside the drying box 20 and on the outside of the air guiding cylinder 24. The top size of the material receiving cylinder 25 is larger than the bottom size. A blanking port 251 is provided at the top of the material receiving cylinder 25. A material receiving groove is formed between the outside of the material receiving cylinder 25 and the drying box 20. The material receiving groove is connected to a screening box 30 through a pipeline. A cyclone separator 26 is externally connected to the top of the drying box 20;

[0054] Screening box 30. A screening plate 31 is installed on the screening box 30. A rotating shaft 33 is rotatably installed in the middle of the screening plate 31. A shoveling plate 34 is installed on the rotating shaft 33. A screening motor 32 is installed at the bottom of the screening plate 31.

[0055] The raw materials enter the position between the two scraping plates 14 inside the granulating box 10. The reduction motor 11 drives the male roller 12 to rotate. The male roller 12 and the female roller 13 are connected by gear transmission. The two female rollers 13 are also driven by gear transmission, and the two female rollers 13 move against the raw material feeding direction. The raw materials enter the granulating groove 131. The scraping plates 14 clean the redundant raw materials on the surface of the granulating groove 131. After cleaning, the male roller 12 and the female roller 13 are adapted to complete granulation. The granules enter the drying box 20 through the material guiding hopper 15 and enter between the air guiding cylinder 24 and the material receiving cylinder 25. The air inlet coil pipe 21 sends air into the drying box 20. The air forms hot air flow after being heated by the electric heating structure 22. The hot air flow blows and dries the granules. The granules are blown by the hot air flow. When the granules are blown to meet the humidity requirements, the granules will be blown by the hot air flow above the air guiding cylinder 24. When exceeding the top of the air guiding cylinder 24, due to the rapid reduction of the air flow pushing force, the granules are prone to disperse around. After the granules are dispersed, they will fall, and after falling, they enter the receiving groove through the material falling port 251. The dried granules enter the screening box 30. The dried granules enter the screening plate 31. The screening motor 32 drives the rotating shaft 33 and the shoveling plate 34 to rotate. After being screened by the screening plate 31, the dried granules are naturally cooled to obtain cat litter granules.

[0056] Example 2

[0057] In Example 1, when the raw materials enter the granulating box 10, they are prone to accumulate, which may cause the problem of inconsistent particle density, such as Figure 3 and Figure 4 As shown, two connecting rods 141 are installed between the two scraping plates 14. A protective cover 142 is installed at the top of the two connecting rods 141. Two ear plates 143 and a motor 144 are installed below the protective cover 142. A rotating lead screw 145 and guide rods 146 located on both sides of the lead screw 145 are installed on the two ear plates 143. The output end of the motor 144 is connected to the lead screw 145. A moving block 147 is installed on the lead screw 145. The moving block 147 is slidably matched with the guide rods 146. A bar 148 is installed at the lower part of the moving block 147. By driving the lead screw 145 to rotate reciprocally by the motor 144, the moving block 147 is driven to move reciprocally, and the bar 148 evenly spreads the raw materials, which is beneficial to controlling the consistency of particle density.

[0058] Example 3

[0059] In Example 1, as Figure 3 shown, an elastic capsule piece 132 is embedded at the notch of the granulating groove 131, and a certain gap is reserved between the elastic capsule piece 132 and the inside of the granulating groove 131. When the granulating bump 121 presses into the granulating groove 131, the raw materials are formed in the granulating groove 131. After forming, the elastic capsule piece 132 can automatically remove the granules.

[0060] Example 4

[0061] In Embodiment 1, as Figure 10 , Figure 11 shown, the shovel plate 34 is arranged obliquely downward. The bottom of the shovel plate 34 contacts the surface of the screening plate 31, and a receiving mesh plate 35 is installed at the top. The receiving mesh plate 35 is arranged obliquely downward, and the included angle between the receiving mesh plate 35 and the screening plate 31 is greater than the included angle between the shovel plate 34 and the screening plate 31. A receiving frame 36 is installed at the top of the receiving mesh plate 35. The top of the receiving frame 36 is open facing the rotation direction, and the top of the receiving frame 36 facing the side of the screening box 30 is also open. A side opening is provided on the side of the screening box 30, and a receiving box 37 is installed outside the screening box 30. The receiving box 37 is connected to the side opening. The mesh sizes of the receiving mesh plate 35 and the screening plate 31 are the same.

[0062] The screening motor 32 drives the shovel plate 34 to rotate. While rotating, the particles are flipped, causing the particles to turn up. This facilitates the non-conforming particles to fall back to the screening plate 31 through the receiving mesh plate 35. Then, the screening plate 31 will let the non-conforming particles fall to the bottom, but a part of the particles will remain to buffer the subsequent incoming particles, avoiding direct rigid collision with the screening plate 31 and reducing the crushing rate. The particles that meet the screening requirements will not pass through the receiving mesh plate 35 until they enter the receiving frame 36 and then into the receiving box 37.

[0063] Embodiment 5

[0064] In Embodiment 4, as Figure 2 shown, a material spreading shaft 38 is installed at the feed inlet of the screening box 30 through a bearing. Material spreading sheets 310 (flexible plastic sheets) are distributed on the material spreading shaft 38, and a material spreading motor 39 is installed outside the screening box 30. The material spreading motor 39 is connected to one end of the material spreading shaft 38.

[0065] After the particles enter the interior of the screening box 30, the material spreading motor 39 drives the material spreading shaft 38 and the material spreading sheets 310 to rotate, spreading the particles evenly on the screening plate 31.

[0066] Embodiment 6

[0067] In Embodiment 1, as Figure 2As shown, a push plate 253 is arranged between the bottom of the receiving barrel 25 and the drying box 20, and two connecting plates with upwardly protruding tops and flush bottoms with the receiving barrel 25 and the bottoms of the air guide barrel 24 are arranged between the inner bottom of the receiving barrel 25 and the side wall of the air guide barrel 24. A certain distance is reserved between the two connecting plates to form a material inlet, and a cylinder 252 is installed on the back of the push plate 253. The cylinder 252 drives the push plate 253 to push the particles between the receiving barrel 25 and the air guide barrel 24 to the top of the air inlet coil 21, wherein the push plate 253 is divided into two states, one state is to separate the area (material inlet) between the receiving barrel 25 and the air guide barrel 24, and the other state is to connect the area (material inlet) between the receiving barrel 25 and the air guide barrel 24.

[0068] Example 7

[0069] In Example 1, Figure 2 As shown, a constraint plate 27 is arranged inside the drying box 20, a side panel 28 is arranged below the constraint plate 27, a bottom plate is arranged outside the bottom of the side panel 28, a spring member 29 is connected between the bottom plate and the constraint plate 27, a filter plate 281 is arranged on the top of the side panel 28, and meshes are arranged on the side panel 28 and the filter plate 281. Since the hot air flow drives the particles upward, the upward air flow may cause the particles to move upward excessively, and the particles may accidentally enter the cyclone separator 26, which may cause the loss of particles.

[0070] Example 8

[0071] In Example 1, Figure 2 , Figure 6 As shown, the material receiving barrel 25 includes an upper barrel 254 and a lower barrel 255, which are connected by a connecting piece, a rotating member 256 is rotatably installed between the upper barrel 254 and the lower barrel 255, and a rotary motor 257 is installed on the side of the lower barrel 255. The rotary motor 257 drives the rotating member 256 to rotate through a gear, and a material spreading plate 258 is installed on the rotating member 256. The rotary motor 257 drives the rotating member 256 to rotate, and the rotating member 256 drives the material spreading plate 258 to rotate. The material spreading plate 258 rotates to perform a rotary spreading process on the material entering between the material receiving barrel 25 and the air guide barrel 24 to avoid local accumulation of particles.

[0072] A processing technology for plant fiber source cat litter, the processing steps are as follows:

[0073] Step 1: Apportionment

[0074] The cat litter material enters the position between the two scraper plates 14 in the granulation box 10, the motor 144 drives the lead screw 145 to rotate and drives the moving block 147 to reciprocate, and the pull bar 148 distributes the cat litter material along the axis direction of the roller assembly;

[0075] Step 2: Granulation

[0076] The reduction motor 11 drives the male roller 12 and the female roller 13 to rotate. The two female rollers 13 rotate against the feeding direction. The scraping plate 14 levels the raw materials in the granulation tank 131. The granulation protrusions 121 on the male roller 12 shape the raw materials in the granulation tank 131. After shaping, the elastic capsule pieces 132 automatically drop the granules, and cat litter granules are obtained;

[0077] Step 3: Drying

[0078] The cat litter granules enter between the air guide cylinder 24 and the material receiving cylinder 25 in the drying box 20 from the feed port. The rotary member 256 and the spreading plate 258 evenly distribute the cat litter granules. The air cylinder 252 drives the pushing plate 253 to send the cat litter granule material above the air inlet coil 21, and continuously sends the cat litter granules above the air inlet coil 21. The air inlet coil 21 sends air into the drying box 20, and the air forms a hot air flow through the electric heating structure 22. The hot air flow dries the cat litter granules on the grid plate 23. The cat litter granules with humidity meeting the requirements will be sent to the top by the hot air and touch the filter plate 281, then disperse around. After dispersion, they lose the upward pushing force and then gradually fall, and enter the receiving groove through the blanking port 251;

[0079] The hot air flow brings the powder during the drying process into the cyclone separator 26;

[0080] Step 4: Screening

[0081] The dried granules in the receiving groove enter the screening box 30 through a pipeline. The spreading motor 39 drives the spreading shaft 38 and the spreading pieces 310 to rotate, and the dried granules are scattered and fall on the screening plate 31. The screening motor 32 drives the shovel plate 34 to rotate and turn the granules up at the same time. The receiving mesh plate 35 drops the granules that do not meet the screening requirements to the bottom of the screening box 30;

[0082] The granules that meet the screening requirements will not pass through the receiving mesh plate 35, enter the interior through the receiving frame 36, and finally enter the receiving box 37. After cooling, the finished cat litter granules are obtained; the granules that do not meet the screening requirements pass through the receiving mesh plate 35 and fall back onto the screening plate 31, and then fall to the bottom of the screening box 30.

[0083] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution and inventive concept of the present invention should be covered within the protection scope of the present invention.

9. A processing technology for plant fiber source cat litter, characterized in that, The processing steps are as follows: Step 1, spreading The cat litter raw materials enter the position between the two scraping plates (14) in the granulating box (10). The motor (144) drives the lead screw (145) to rotate to drive the moving block (147) to reciprocate. The bar (148) spreads the cat litter raw materials along the axial direction of the pair of roller assemblies. Step 2, granulating The reduction motor (11) drives the male roller (12) and the female roller (13) to rotate. The two female rollers (13) rotate against the feeding direction. The scraping plate (14) levels the raw materials in the granulating groove (131). The granulating protrusions (121) on the male roller (12) shape the raw materials in the granulating groove (131). After shaping, the elastic capsule pieces (132) automatically drop the particles, and cat litter particles are obtained. Step 3, drying The cat litter particles enter between the air guide cylinder (24) and the material receiving cylinder (25) inside the drying box (20) from the feed inlet. The rotary member (256) and the spreading plate (258) evenly distribute the cat litter particles. The air cylinder (252) drives the pushing plate (253) to send the cat litter particle material above the air inlet coil (21), continuously sending the cat litter particles above the air inlet coil (21). The air inlet coil (21) sends air into the drying box (20), and the air forms a hot air stream through the electric heating structure (22). The hot air stream dries the cat litter particles on the grid plate (23). The cat litter particles with humidity meeting the requirements are sent to the top by the hot air and touch the filter plate (281), then disperse around. After dispersion, they lose the upward pushing force and then gradually fall, entering the receiving groove through the blanking port (251); The hot air stream brings the powder during the drying process into the cyclone separator (26); Step 4, screening The dried particles in the receiving groove enter the screening box (30) through a pipeline. The material spreading motor (39) drives the material spreading shaft (38) and the material spreading pieces (310) to rotate, and the dried particles are scattered and fall on the screening plate (31). The screening motor (32) drives the shoveling plate (34) to rotate and turn the particles up simultaneously. The receiving mesh plate (35) drops the particles that do not meet the screening particle requirements to the bottom of the screening box (30); The particles that meet the screening particle requirements do not pass through the receiving mesh plate (35), enter the interior through the receiving frame (36), and finally enter the receiving box (37). After cooling, the finished cat litter particles are obtained; the particles that do not meet the screening particle requirements pass through the receiving mesh plate (35) and fall back onto the screening plate (31), and then fall to the bottom of the screening box (30).
