Description

Technical Field

[0001] The invention belongs to the technical field of silica gel cat litter production, in particular to drying equipment used for silica gel cat litter production. Background Art

[0002] Silica gel cat litter is a highly active adsorption material, usually made by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid soaking.

[0003] During the production process of silica cat litter, the silica cat litter needs to be washed with water, and then the washed silica cat litter can be directly dried. However, since the silica cat litter is relatively hard in actual use, and the newly produced silica cat litter has many sharp corners, and the existing technology cannot polish each silica cat litter well, the silica cat litter will pierce the soles of cats in actual use. At the same time, when the sharp corners on the silica cat litter are processed, the silica dust generated will adhere to the surface of the silica cat litter, so that when the silica cat litter is used, the pet cat will inhale the dust remaining in the silica cat litter, causing the cat to develop silicosis;

[0004] In addition, since the coarse-pore silica gel particles used in the manufacture of silica cat litter have a large diameter, when the silica cat litter is dried, the water on the outside of the silica cat litter is dried, while the inside is still in an undried state. When the silica cat litter is completely dried, it is necessary to increase the drying time, thereby reducing the production efficiency of the silica cat litter. Summary of the invention

[0018] Beneficial Effects

[0019] A. The present invention controls the operation of an external vacuum pump, so that the air in the cooling box will be extracted through the connecting pipe, so that the air pressure in the cooling box is reduced. Because under low air pressure, the air pressure on the molecules is small and the activity is relatively high, so the water remaining in the silica gel cat litter will sublime, so that part of the water in the silica gel cat litter is removed, thereby facilitating the subsequent rapid drying of the silica gel cat litter. At the same time, some dust floating in the cylinder can also be sucked out through the connecting pipe.

[0020] B. The present invention also has a rotating plate that is arranged in an arc shape, so that the rotating plate can better flip the silica cat litter, so that the silica cat litter is flipped and more dispersed, thereby facilitating the cooling box to quickly cool the silica cat litter, so that the sharp corners on the silica cat litter are quickly embrittled, thereby accelerating the removal of the sharp corners on the silica cat litter.

[0021] C. The present invention also inserts the pressing plate into the round hole on the cylinder, so that the silica cat litter blocked in the round hole is poked out by the pressing plate. At the same time, since the round holes in the first three rows on the cylinder are vertically downward, and the round holes in the last two rows are inclined downward, when the rotating plate rotates clockwise, the round holes in the first three rows are prevented from limiting the silica cat litter when the pressing plate presses the silica cat litter, making it difficult for the silica cat litter to fall out of the round holes.

[0022] D. In the process of moving the silica cat litter, the front lower part of the upper conveyor belt is set as an inclined surface, so that the silica cat litter enters between the two conveyor belts in a single manner, thereby avoiding the stacking of the silica cat litter and affecting the squeezing of the silica cat litter by the conveyor belts. In addition, since the spacing between the two conveyor belts is smaller than the diameter of the silica cat litter, the silica cat litter entering between the two conveyor belts will be compressed, so that the water inside the silica cat litter is squeezed out, which is convenient for the silica cat litter to be quickly dried;

[0023] At the same time, the present invention also avoids the problem that, when the silica gel cat litter is dried, the water on the outside of the silica gel cat litter is dried, while the inside of the silica gel cat litter is still in an undried state. When the silica gel cat litter needs to be completely dried, the drying time needs to be increased, which reduces the production efficiency of the silica gel cat litter.

[0024] E. The present invention also provides an adsorption layer on the outer surface of the conveyor belt, so that when the silica gel cat litter is dried, the dust remaining on the silica gel cat litter will be adsorbed by the adsorption layer, thereby preventing the pet cat from inhaling the dust remaining in the silica gel cat litter when the silica gel cat litter is used later, thereby preventing the cat from developing silicosis.

[0040] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0041] Example 1

[0042] refer to Figure 1-6 The drying equipment shown in the figure for producing silica gel cat litter comprises a base frame 1 and a cooling box 2; the cooling box 2 is fixedly connected to the front upper part of the base frame 1;

[0043] It also includes a cylinder 3, a power assembly, a connecting pipe 4, a filter plate 5, a rotating plate 7, a pressing plate 8, a material discharge system, a pushing assembly and a drying assembly; the cylinder 3 is fixedly connected to the upper inner part of the cooling box 2; the bottom frame 1 is connected to the power assembly, the power assembly and the cylinder 3 are connected to each other, and a feed port is provided on the upper outer ring surface of the cylinder 3; the upper outer ring surface of the cylinder 3 is connected to a connecting pipe 4 by bolts, and one end of the connecting pipe 4 passes through the cooling box 2; the filter plate 5 is connected to the lower inner part of the cooling box 2 by plugging or clamping, so that the filter plate 5 can be easily replaced and maintained; the power assembly is connected to three rotating plates 7 that are equidistantly distributed in a ring shape; The rotating plate 7 is driven to rotate by the power component, so that the rotating plate 7 will flip the silicone cat litter in the cylinder 3 to avoid accumulation of the silicone cat litter and reduce the cooling speed of the silicone cat litter; each rotating plate 7 is fixedly connected to ten pressing plates 8 equidistantly distributed on the left and right through torsion spring rods; the cooling box 2 is connected to a feeding system; the front upper part of the base frame 1 is connected to a pushing component, and the pushing component is located in front of the cooling box 2; the rear upper part of the base frame 1 is connected to two drying components, the two drying components are symmetrically distributed on the left and right, and the two drying components have the same structure, and the feeding system is connected to the two drying components.

[0044] The cooling box 2 also includes a collecting box 6 ; the lower inner side of the cooling box 2 is connected to the collecting box 6 by plugging, so that the staff can clean the impurities such as sharp corners in the collecting box 6 easily.

[0045] A strip through groove 31 is provided at the rear of the outer ring surface of the cylinder 3, so that the larger silicone cat litter will flow out through the strip through groove 31 after the sharp corners are removed, and five rows of arc-shaped and equidistantly distributed circular holes are provided at the lower part of the outer ring surface of the cylinder 3, and the number of circular holes in each row is consistent with the number of pressing plates 8, so that the smaller silicone cat litter will flow out through the circular holes, and the circular holes in the first three rows are vertically downward, while the circular holes in the last two rows are inclined downward. Looking from left to right as a reference, the power component will drive the rotating plate 7 to rotate clockwise, and the pressing plate 8 will rotate synchronously with the rotating plate 7, so that a small amount of silicone cat litter stuck in the circular holes will be pressed down by the pressing plate 8, and at the same time, it also avoids the circular holes in the first three rows from limiting the silicone cat litter when the pressing plate 8 presses the silicone cat litter.

[0046] The rotating plate 7 is set to an arc shape, so that the rotating plate 7 can better flip the silica gel cat litter, making the silica gel cat litter more dispersed after being flipped, which is convenient for the cooling box 2 to quickly cool the silica gel cat litter, so that the sharp corners on the silica gel cat litter quickly become brittle, thereby accelerating the removal of the sharp corners on the silica gel cat litter.

[0047] The power assembly includes a motor 201 and a transmission shaft 202; the motor 201 is bolted to the upper left side of the cooling box 2, and the output shaft of the motor 201 passes through the cooling box 2; the transmission shaft 202 is rotatably connected to the middle of the cylinder 3, and one end of the transmission shaft 202 is fixedly connected to the output shaft of the motor 201; the transmission shaft 202 is fixedly connected to the rotating plate 7.

[0048] The unloading system includes a first push rod 301, a first connecting plate 302, a second push rod 303, a second connecting plate 304, a hopper 305 and a discharging assembly; two first push rods 301 are bolted to the upper side of the cooling box 2, and the two first push rods 301 are symmetrically distributed on the left and right; the telescopic parts of the two first push rods 301 are commonly fixedly connected to the first connecting plate 302; two second push rods 303 are bolted to the lower side of the first connecting plate 302; the telescopic parts of the two second push rods 303 are commonly fixedly connected to the second connecting plate 304; the upper side of the cooling box 2 is fixedly connected and connected to the hopper 305, and the lower side of the hopper 305 is connected to the feed port on the cylinder 3; the rear side of the cooling box 2 is connected to the discharging assembly, and the discharging assembly is connected to the cylinder 3.

[0049] When using the drying equipment for producing silica gel cat litter, first, the initial position of the second connecting plate 304 is located above the hopper 305, and the connecting pipe 4 is connected to the external vacuum pump. Then the staff transfers the washed silica gel cat litter to the hopper 305, and then the silica gel cat litter enters the cylinder 3 through the feed port on the cylinder 3. When the washed silica gel cat litter is completely transferred to the cylinder 3, the first push rod 301 can be controlled to move the first connecting plate 302 downward, and the second push rod 303 and the second connecting plate 304 move synchronously with the first connecting plate 302, and then the second connecting plate 304 will contact the bottom of the hopper 305, so that the hopper 305 is blocked. Under the cooperation of the feeding system and the pushing component, the cooling box 2 will be in a closed state at this time. The cylinder 3 is in a closed state, so that the cooling box 2 can process the silica gel cat litter, and then the external vacuum pump is controlled to work, so that the air in the cooling box 2 will be extracted through the connecting pipe 4, so that the air pressure in the cooling box 2 is reduced. Because under the condition of low air pressure, the molecules are subjected to less air pressure and are relatively active, so the water remaining in the silica gel cat litter will sublime, so that most of the water in the silica gel cat litter is removed, and then it is convenient for the subsequent rapid drying of the silica gel cat litter. At the same time, some dust floating in the cylinder 3 can also be sucked out through the connecting pipe 4. In this process, the cooling box 2 is controlled to work at the same time, and the cooling box 2 will cool the silica gel cat litter, so that the sharp corners on the silica gel cat litter will quickly become brittle, and in this state, the high-speed ejected frozen particles will hit the silica gel cat litter. The sharp corners on the cat litter are effectively removed. During the operation of the cooling box 2, the reference is viewed from left to right. At the same time, the motor 201 is controlled to drive the transmission shaft 202 to rotate clockwise, and the rotating plate 7 and the pressing plate 8 rotate synchronously with the transmission shaft 202. Since the rotating plate 7 is arranged in an arc shape, the rotating plate 7 can better flip the silica gel cat litter, so that the silica gel cat litter is flipped and more dispersed, thereby facilitating the rapid cooling of the silica gel cat litter by the cooling box 2, so that the sharp corners on the silica gel cat litter are quickly embrittled, thereby accelerating the removal of the sharp corners on the silica gel cat litter. As the rotating plate 7 continuously flips the silica gel cat litter, the smaller silica gel cat litter with the sharp corners removed will flow out through the circular hole on the cylinder 3. When the silica gel cat litter flows out through the circular hole, there is a small amount of silica The silica cat litter is stuck in the round hole, so when the pressing plate 8 rotates to the side of the round hole, the pressing plate 8 will be separated from the inner wall of the cylinder 3, so that the torsion spring rod connected to the pressing plate 8 changes from a compressed state to a normal state. During the transformation process of the torsion spring rod, the pressing plate 8 will be driven to rotate downward and reset, so that the pressing plate 8 is inserted into the round hole on the cylinder 3, so that the silica cat litter blocked in the round hole is poked out by the pressing plate 8. At the same time, since the round holes in the first three rows of the cylinder 3 are vertically downward, and the round holes in the last two rows are inclined downward, when the rotating plate 7 rotates clockwise, the round holes in the first three rows are avoided from limiting the silica cat litter when the pressing plate 8 presses the silica cat litter, making it difficult for the silica cat litter to fall from the round holes, and the silica cat litter passing through the round holes will fall on the filter plate 5.At the same time, the removed sharp corners will also fall onto the filter plate 5 through the round holes, and then the sharp corners will fall into the collection box 6 through the filter holes on the filter plate 5 to be collected, while the larger silica cat litter will be discharged through the strip-shaped through groove 31, so that the silica cat litters of different sizes can be separated, thereby improving the quality of the silica cat litter.

[0050] Example 2

[0051] On the basis of Example 1, Figure 6-8 As shown, the discharging assembly includes a first connection box 306, a first blanking plate 307, an electric door 308, a second connection box 309, a second blanking plate 310, a connection frame 311, a third push rod 312, an L-shaped plate 313 and a blocking plate 314; the middle part of the front side of the cooling box 2 is connected to the first connection box 306 through a flange bolt; the first blanking plate 307 is fixedly connected to the right front side of the first connection box 306; the electric door 308 is slidably connected to the lower part of the cooling box 2; the lower part of the front side of the cooling box 2 is connected to the second connection box 309; the second blanking plate is fixedly connected to the left front side of the second connection box 309 310, the first unloading plate 307 and the second unloading plate 310 are respectively connected to a drying component; the strip-shaped through groove 31 is fixedly connected to a connecting frame 311, and one end of the connecting frame 311 passes through the cooling box 2; two third push rods 312 are bolted to the middle of the rear side of the cooling box 2, and the two third push rods 312 are symmetrically distributed on the left and right, and the third push rods 312 are located in front of the first connecting box 306; the telescopic parts of the two third push rods 312 are each fixedly connected to an L-shaped plate 313; the front sides of the two L-shaped plates 313 are commonly fixedly connected to a sealing plate 314, and the sealing plate 314 is slidably connected to the connecting frame 311.

[0052] The lower inner sides of the first connection box 306 and the second connection box 309 are both arranged as inclined surfaces, so as to facilitate the feeding of the silica cat litter and prevent the silica cat litter from gathering or staying in the first connection box 306 and the second connection box 309 .

[0053] The pushing assembly includes a connecting seat 401, a multi-stage telescopic rod 402 and a push plate 403; two connecting seats 401 are fixedly connected to the front upper side of the base frame 1; a multi-stage telescopic rod 402 is bolted to each of the two connecting seats 401; the telescopic parts of the two multi-stage telescopic rods 402 are commonly fixedly connected to the push plate 403, and a plurality of bristles equidistantly distributed on the left and right are arranged on the lower side of the push plate 403, so that when the push plate 403 pushes the silica cat litter on the filter plate 5, the bristles on the push plate 403 will clean the sharp corners remaining on the filter plate 5.

[0054] After the processing of the sharp corners on the silica gel cat litter is completed, the third push rod 312 is controlled to push the L-shaped plate 313 backwards, and the blocking plate 314 moves synchronously with the L-shaped plate 313, so that the strip groove 31 will be opened, and then through the cooperation of the rotating plate 7, the larger silica gel cat litter in the cylinder 3 will flow out through the strip groove 31, and after flowing out, the larger silica gel cat litter will flow into the first connecting box 306 along the connecting frame 311. Since the lower side of the first connecting box 306 is set as an inclined surface, the larger silica gel cat litter flows into the first unloading plate 307 along the inclined surface, avoiding the larger silica gel cat litter from gathering or staying in the first connecting box 306 and then flowing into the corresponding drying component. At the same time, the electric door 308 is controlled to move The push plate 403 moves downward to open the discharge port on the cooling box 2, and then the multi-stage telescopic rod 402 is controlled to move the push plate 403 backward, and then the push plate 403 will push the smaller silica gel cat litter on the filter plate 5. In this process, since the lower side of the push plate 403 is provided with a plurality of bristles evenly distributed on the left and right, the bristles will clean the sharp corners remaining on the filter plate 5, and then the smaller silica gel cat litter will enter the second connecting box 309 through the discharge port in the cooling box 2. Since the upper side of the second connecting box 309 is set as an inclined surface, the smaller silica gel cat litter flows into the second unloading plate 310 along the inclined surface, and then flows into the corresponding drying component, and the two types of silica gel cat litters are dried respectively through the two drying components.

[0055] Example 3

[0056] On the basis of Example 2, Figure 9-10 As shown, the drying assembly on the left includes a support plate 502, a conveyor belt 503 and a dryer 504; two support plates 502 are fixedly connected to the upper rear part of the bottom frame 1; a conveyor belt 503 is rotatably connected to the upper and lower parts of the opposite sides of the two support plates 502, and the conveyor belt 503 is a heat-conductive material, and an adsorption layer is provided on the outer surface of the upper conveyor belt 503, so that when the silica gel cat litter is dried, the dust remaining on the surface of the silica gel cat litter will be adsorbed by the adsorption layer; a dryer 504 is bolted to the upper and lower parts of the opposite sides of the two support plates 502, and the dryer 504 is located in the conveyor belt 503, and twenty ventilation slots are opened on the upper and lower sides of the dryer 504, which are equidistantly distributed front and back, and the number of ventilation slots can be set according to actual conditions, so that the hot air in the dryer 504 will be blown out through the ventilation slots, and then the silica gel cat litter is dried.

[0057] The lower front portion of the upper conveyor belt 503 is set as an inclined surface, so that the silica cat litter enters between the two conveyor belts 503 in a single layer, avoiding the stacking of the silica cat litter and affecting the squeezing of the silica cat litter by the conveyor belt 503.

[0058] It also includes a scraper 501 ; the scraper 501 is fixedly connected to the upper rear portion of the base frame 1 .

[0059] It is explained here that since the two drying components have the same structure and operate in the same way, in order to better describe them, the drying component on the left will be described as an example. Since the silica gel cat litter particles flowing out of the first unloading plate 307 are smaller than the silica gel cat litter particles flowing out of the second unloading plate 310, and the gap between the two conveyor belts 503 on the left is smaller than the gap between the two conveyor belts 503 on the right, the silica gel cat litter flowing out of the first unloading plate 307 and the second unloading plate 310 will enter the corresponding conveyor belt 503. At this time, the control The upper and lower conveyor belts 503 work simultaneously, so that the lower conveyor belt 503 will drive the silicone cat litter to move backwards. During the movement of the silicone cat litter, since the lower front part of the upper conveyor belt 503 is set as an inclined surface, the silicone cat litter enters between the two conveyor belts 503 in a single manner, thereby avoiding the stacking of the silicone cat litter and affecting the squeezing of the silicone cat litter by the conveyor belts 503. In addition, since the spacing between the two conveyor belts 503 is smaller than the diameter of the silicone cat litter, the silicone cat litter entering between the two conveyor belts 503 will The silica cat litter is compressed so that the water inside the silica cat litter is squeezed out, which is convenient for the silica cat litter to be dried quickly. At the same time, it also avoids the problem in the prior art that when the silica cat litter is dried, the water outside the silica cat litter is dried, but the inside is still in an undried state. When the silica cat litter needs to be completely dried, the drying time will be increased, but the production efficiency of the silica cat litter will be reduced. At the same time, when the conveyor belt 503 squeezes and transports the silica cat litter, the dryer 504 is controlled to work at the same time, and the hot air generated by the dryer 504 will pass through the dryer 504. The silica gel cat litter is blown out through the ventilation slots on the conveyor belt 503, and then the silica gel cat litter is dried. At the same time, since an adsorption layer is arranged on the outer surface of the conveyor belt 503, the dust remaining on the surface of the silica gel cat litter will be adsorbed by the adsorption layer when the silica gel cat litter is dried, so as to avoid the pet cat inhaling the dust remaining in the silica gel cat litter when using the silica gel cat litter in the future, which may cause silicosis in the cat. Under the action of the scraper 501, the dust on the adsorption layer will be scraped off and collected from the adsorption layer on the outer surface of the conveyor belt 503 by the scraper 501, and then the dried silica gel cat litter will be collected by the external collection frame.

[0060] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
