Description

Technical Field

[0001] This invention relates to the field of de-icing agent production and preparation technology, specifically to an environmentally friendly de-icing agent production and preparation equipment and its preparation method. Background Technology

[0002] Snow and ice accumulation on roads in winter has always been a major problem hindering highway traffic. Because roads are covered with ice and snow, the friction between tires and the ground decreases, greatly increasing the risk of traffic accidents. In severe cases, this can paralyze highway traffic and even cause significant loss of life and property. In practice, high-level snow removal in winter mainly relies on mechanical snow removal and de-icing agent technology to ensure rapid reopening of traffic after snowfall. De-icing agents are irreplaceable by other methods due to their high snow-melting efficiency, good effect, ease of use, and excellent anti-icing and anti-skid properties. De-icing agents, also known as de-icing salts or road antifreeze agents, are agents that lower the freezing point of water and promote the melting of ice and snow. They are mainly used in winter at airports, highways, squares, parking lots, railways, and city streets to melt ice and snow and prevent freezing. Their main components are salts such as sodium chloride, calcium chloride, and magnesium chloride.

[0003] Currently used de-icing agents can be broadly categorized into two types: The first type is chloride-based de-icing agents, which primarily consist of one or more of the following: sodium chloride, calcium chloride, magnesium chloride, and potassium chloride (commonly known as de-icing salts). These agents have a significant impact on roads, the environment, and vegetation, especially sodium chloride. The second type is non-chloride organic de-icing agents, primarily composed of calcium acetate, magnesium acetate, potassium acetate, or various special organic compounds such as alcohols and urea. These agents have less impact on roads, the environment, and vegetation and are more environmentally friendly.

[0004] The production of the aforementioned environmentally friendly de-icing agent generally involves steps such as raw material crushing, proportioning, mixing, granulation, crushing and screening, collection, and recycling. During granulation, the raw materials are compressed, and after crushing, the crushing mechanism generates a certain amount of raw material debris and fragments, while also breaking the raw material spheres. Therefore, screening, collection, and recycling are necessary. After recycling, the materials need to be manually transported back for crushing and regranulation, which requires a significant amount of manual labor. Furthermore, during granulation, some raw materials leak directly into the lower part of the granulator through the gaps between the granulation rollers, increasing the generation of debris and the workload of recycling.

[0005] Therefore, an environmentally friendly de-icing agent production and preparation equipment and its preparation method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an environmentally friendly de-icing agent production and preparation equipment and method to solve the problems of complex processes, high manpower requirements and excessive debris generation mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly de-icing agent production and preparation equipment, including a preparation tank, which has multiple vertically connected channels inside;

[0008] The lifting screw belt is rotatably positioned inside the preparation tank at the lower middle part, with its shaft extending out of the preparation tank and driven by an external drive mechanism via a belt. It is used for mixing the input raw materials and conveying them upwards.

[0009] The molding structure has three sets of rollers inside, which are fixed in the upper middle part of the preparation tank, and can be used for granulation, sand control and raw material recycling of input raw materials.

[0010] The preparation tank includes a tank body, and a return material ramp is provided at the top inside the tank body. The port of the return material ramp is connected to a straight return material ramp inside the tank body wall. The straight return material ramp extends downward along the tank body wall to the collection pipe and is connected to an inclined channel inside the collection pipe. A mesh plate is integrally provided inside the straight return material ramp near the inclined channel.

[0011] The molding structure includes an installation component. A material trough that runs vertically through the center of the installation component is provided. A pelletizing roller, a conveying roller, and a pelletizing tube are symmetrically arranged on both sides of the material trough from bottom to top. A sliding channel that communicates with the straight return channel is provided on the lower side of the conveying roller and the pelletizing tube.

[0012] One of the pelletizing tubes is internally connected to a roller, and several cams are fixed radially at equal intervals on a rod inside the pelletizing tube. The side of the cams is always in contact with the ball end of the spring rod. The side of the outer tube of the spring rod is fixed to the pelletizing tube by a support rod, and the output end is fixedly connected to the side of the pelletizing tube by an arc-shaped support. The pelletizing tube is slidably disposed inside a sliding hole opened on the side of the pelletizing tube.

[0013] A drop plate is slidably installed inside the material channel directly below the discharge port of the pelletizing tube. Several lifting springs are integrally connected to both sides of the bottom surface of the drop plate, and the movement is limited by the lifting springs. Several equidistant connecting rods are integrally connected to the middle position of the ground of the drop plate, and one end of the connecting rod extends into the interior of the straight return channel and is fixed to the diamond cone spike frame at the lower end.

[0014] Another pelletizing tube has a cutting tube integrally provided on the side at the same position as the pelletizing tube, and a blow hole is opened inside the cutting tube according to the position of the cutting tube. One end of the central hole of the blow hole extends through along the rotating shaft, and the through end is connected to the output end of the air pump.

[0015] Preferably, the bottom of the tank is open, and a base is bolted to the open port. A lifting screw is rotatably disposed inside the base, and the shaft of the lifting screw extends through the base. A feed nozzle for inputting mixed raw materials is provided on the side of the tank near the lower port. A collecting pipe is bolted to the upper middle part of the tank. The upper surface of the collecting pipe is concave, and the upper end of the lifting screw is rotatably disposed inside the collecting pipe, with the upper end of the lifting screw flush with the bottom of the concave surface.

[0016] Preferably, the side of the tank body is provided with an inwardly extending finished product outlet at the position corresponding to the molding structure, and the finished product outlet is pointed on the upper surface of a portion of the tube inside the straight return channel, and the width of the tube is smaller than the width of the straight return channel.

[0017] Preferably, the center of the mounting component has a vertically penetrating material trough, and three sets of spaces communicating with the material trough are symmetrically arranged on both sides of the material trough from top to bottom. The lowest space has a rotatable granulation roller, the middle space has a rotatable conveying roller, and the uppermost space has a fixed pelletizing tube.

[0018] Preferably, the shafts at both ends of the granulating roller and the conveying roller extend through the mounting component and the tank, and the extending ends are integrally connected to gears or pulleys. The shafts in the same group that fix the pulleys are not connected to gears or pulleys. The gears in the same group mesh with each other for transmission, and the pulleys in the upper and lower groups are driven by toothed belts. The holes on the surface of the conveying roller are opened according to the grooves on the surface of the granulating roller.

[0019] Preferably, the pelletizing tube is divided into a tube body and a roller body. The shaft at one end of the tube body extends through the mounting component and the tank body, and the shaft body has an internal through hole, which is rotatably connected to the internal roller through the shaft hole. The side of the gear at the end of the internal roller is connected to the gear at the end of the conveying roller through a connecting gear, and the radius of the gear at the end of the internal roller is much smaller than the radius of the gear at the end of the conveying roller.

[0020] Preferably, the air pump is mounted on the outside of the tank via a mounting bracket on the side of the tank.

[0021] Preferably, the lifting spring is suspended directly above the mesh plate, and there is sufficient gap between each spike.

[0022] A preferred method for preparing an environmentally friendly de-icing agent includes the following specific steps:

[0023] S1. First, the premixed raw materials are fed into the feed nozzle via a conveyor belt, then slide into the tank from the feed nozzle and fall above the base. Then, the lifting screw belt driven by the external drive device will spiral the raw materials up and down, and transfer the raw materials to the upper part of the collection pipe for accumulation.

[0024] S2. The raw material accumulated above the collecting pipe will be pressed into a pad with spherical protrusions on the surface by the granulating roller driven by the external equipment, and conveyed upward to the conveying rollers. With the assistance of the conveying rollers, it will be conveyed to the pelletizing pipes.

[0025] S3. When the pressed raw material pad is conveyed to the pelletizing tube, the rapidly rotating internal roller will drive the cam to push the output end of the spring rod to slide out of the spring tube, and at the same time push the cutting tube along the pelletizing tube to approach the spherical protrusion on the surface of the raw material pad, until the cutting tube cuts together at the spherical protrusion, completing the separation of the spherical protrusion and the raw material pad. Then the air pump will blow air into the blow hole, and the cut spherical raw material will roll along the cutting tube into the pelletizing tube under the action of the gas, and fall into the slide channel from the material port on the lower side of the pelletizing tube, and be output from the finished product outlet along the slide channel. At this time, the output raw material spheres basically do not contain raw material debris.

[0026] S4. When the raw material ball is fed into the chute, it will first fall on the surface of the drop plate. Under the gravity of the raw material ball, the drop plate will move down along the bottom lifting spring. The moving lifting spring will simultaneously drive the connecting rod and the diamond cone spike frame to move down. The moving diamond cone spike frame will penetrate into the mesh of the screen plate. After the raw material ball rolls over, the drop plate will return to its original position under the action of the lifting spring. This process will be performed after each cutting of the raw material ball.

[0027] S5. The cut raw material pad will continue to be conveyed upwards and enter the interior of the return chute along the chute. It will then fall into the straight return chute along the return chute and then fall onto the screen plate surface along the straight return chute through the diamond cone spikes. If there are large blocks, the up-and-down moving diamond cone spikes will crush the blocks. Then the raw material will pass through the screen plate and be conveyed back to the top of the collection pipe along the opened channel to participate in the granulation operation again.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. This invention, through the arrangement of a tank, base, collection pipe, lifting screw belt, mounting parts, trough, granulation roller, conveying roller mesh, and pelletizing pipe, enables the spiral conveying and mixing of raw materials from bottom to top. Then, it continues to perform granulation, auxiliary conveying, and pelletizing operations on the mixed raw materials from bottom to top. During this process, it can effectively prevent raw materials from passing through the gaps in the roller body, reducing the amount of raw materials that need to be recycled, and correspondingly reducing the workload required for recycling.

[0030] 2. This invention, through the installation of mounting components, a material trough, a granulation roller, a conveying roller screen, a pelletizing tube, an internal roller, a cam, a spring rod, a cutting tube, a blow hole, and an air pump, can quickly perform pelleting of the compressed raw material by reciprocating cutting. After pelleting, the pelleted raw material is separated and transported along a designated path by blowing air through a single hole. Compared with the current dispersing pelleting method, there is no breakage of the pellets, which can ensure the integrity of the pellets to the greatest extent and avoid the generation of a large number of compressed fragments.

[0031] 3. This invention, through the configuration of a tank, a return chute, a straight return chute, a mesh plate, mounting components, a material trough, a sliding chute, a drop plate, a connecting rod, a diamond-shaped cone spike frame, and lifting springs, can recover the pressed raw material after pelletizing. Then, by utilizing the downward force generated during continuous granulation and the elastic effect of the lifting springs, the diamond-shaped cone spike frame is driven up and down reciprocally. During the reciprocating motion, the recovered raw material is crushed and guided downward, preventing large pieces of raw material from affecting the granulation process. Compared with current environmentally friendly de-icing agent production equipment, it does not produce a large amount of raw material debris and fragments, and the corresponding recovery step can be eliminated, significantly improving the efficiency of environmentally friendly de-icing agent production and reducing the workload generated during the granulation process.

[0046] 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.

[0047] Please see Figures 1 to 9 This invention provides a technical solution for an environmentally friendly de-icing agent production and preparation equipment and its preparation method:

[0048] An environmentally friendly de-icing agent production and preparation equipment, comprising:

[0049] Preparation tank 1 has multiple channels that are connected vertically inside;

[0050] The lifting screw belt 2 is rotatably positioned inside the middle and lower part of the preparation tank 1, with its shaft extending out of the preparation tank 1 and driven by an external drive mechanism via a belt, for mixing the input raw materials and conveying them upwards.

[0051] The molding structure 3 has three sets of rollers inside, which are fixed in the upper middle part of the preparation tank 1. It can granulate the input raw materials, control sand, and recycle the raw materials.

[0052] The preparation tank 1 includes a tank body 101, the bottom of which is open, and a base 102 is bolted to the open port. A lifting screw 2 is rotatably disposed inside the base 102, and the shaft of the lifting screw 2 extends out of the base 102. A feed nozzle 1011 for feeding mixed raw materials is provided on the side of the tank body 101 near the lower port. A collecting pipe 103 is bolted to the upper middle part of the tank body 101. The upper surface of the collecting pipe 103 is concave, and the upper end of the lifting screw 2 is rotatably disposed inside the collecting pipe 103, and the upper end of the lifting screw 2 is flush with the bottom of the concave surface.

[0053] The molding structure 3 includes a mounting component 301. A material trough 3011, which runs vertically through the center of the mounting component 301, is provided. Three sets of spaces communicating with the material trough 3011 are symmetrically provided on both sides of the material trough 3011 from top to bottom. A granulating roller 302 is rotatably installed in the bottom space, a conveying roller 303 is rotatably installed in the middle space, and a pelletizing tube 304 is fixedly installed in the top space. A sliding channel 3012 communicating with a straight return channel 1013 is provided on the lower side of the middle and top spaces. The shafts at both ends of the granulating roller 302 and the conveying roller 303 extend through the mounting component 301 and the tank 101, and the ends are integrally connected to gears or pulleys. The shafts of the same group that fixes the pulleys are not connected to gears or pulleys. The gears in the same group mesh with each other for transmission, and the pulleys in the upper and lower groups are driven by a toothed belt. The holes on the surface of the conveying roller 303 are opened according to the grooves on the surface of the granulating roller 302.

[0054] During operation, the premixed raw materials are first fed into the feed nozzle 1011 via a conveyor belt. Then, the raw materials slide into the tank 101 through the feed nozzle 1011 and fall above the base 102. The lifting screw 2, driven by an external drive device, then spirals the raw materials upwards to the upper part of the collecting pipe 103 for accumulation. The raw materials accumulated above the collecting pipe 103 are pressed into a pad-shaped surface with spherical protrusions by the granulating roller 302 driven by the external device and conveyed upwards to the conveying rollers 303. With the assistance of the conveying rollers 303, they are conveyed to the pelletizing pipes 304. After pelletizing in the pelletizing pipes 304, they continue to be conveyed upwards to the return chute 1012.

[0055] In summary, by configuring the tank 101, base 102, collection pipe 103, lifting screw belt 2, mounting component 301, material trough 3011, granulation roller 302, conveying roller mesh 303, and pelletizing pipe 304, the raw materials can be conveyed and mixed in an upward spiral manner. Then, the mixed raw materials are granulated, assisted in conveying, and pelletized in an upward manner. During this process, it is possible to effectively prevent the raw materials from passing through the gaps in the rollers, thereby reducing the amount of raw materials that need to be recycled and correspondingly reducing the workload required for recycling.

[0056] As one embodiment of the present invention, such as Figures 5 to 7 As shown, the pelletizing tube 304 is divided into a tube body and a roller body. A shaft at one end of the tube body extends through the mounting component 301 and the tank body 101. The shaft has an internal through-hole and is rotatably connected to an internal roller 3041 via the through-hole. The side of the gear at the end of the internal roller 3041 is connected to the gear at the end of the conveyor mesh 303 via a connecting gear. The radius of the gear at the end of the internal roller 3041 is much smaller than the radius of the gear at the end of the conveyor mesh 303. 41 extends into and connects to the inside of the pelletizing tube 304, and several cams 3042 are fixed radially at equal intervals on the rod inside the pelletizing tube 304. The side of the cam 3042 is always in contact with the ball end of the spring rod 3043. The side of the outer tube of the spring rod 3043 is fixed to the pelletizing tube 304 through the support rod, and the output end is fixedly connected to the side of the cutting tube 3044 through the arc-shaped support. The cutting tube 3044 is slidably arranged inside the sliding hole opened on the side of the pelletizing tube 304.

[0057] A cutting tube 3044 is integrally provided on the side of the roller body at the same position as the pelletizing tube 304, and a blow hole 3045 is opened inside the cutting tube 3044 according to the position. The blow hole 3045 is in the shape of a grid, and one end of the central hole extends through along the rotating shaft. The through end is connected to the output end of the air pump 3046. The air pump 3046 is installed on the outside of the tank 101 through the mounting bracket on the side of the tank 101.

[0058] During operation, when the pressed raw material pad is conveyed to the pelletizing tubes 304, the rapidly rotating internal roller 3041 drives the cam 3042 to push the output end of the spring rod 3043 out of the spring tube and simultaneously push the cutting tube 3044 along the pelletizing tube 304 toward the spherical protrusion on the surface of the raw material pad until the cutting tube 3044 cuts together at the spherical protrusion, completing the separation of the spherical protrusion from the raw material pad. Then, the air pump 3046 blows air into the blowhole 3045, and the cut spherical raw material rolls into the pelletizing tube 304 along the cutting tube 3044 under the action of the gas, and falls into the sliding channel 3012 from the material outlet on the lower side of the pelletizing tube 304, and is output from the finished product outlet 1014 along the sliding channel 3012.

[0059] In summary, by configuring the mounting component 301, material trough 3011, granulation roller 302, conveyor roller 303, pelletizing tube 304, internal roller 3041, cam 3042, spring rod 3043, cutting tube 3044, blowing hole 3045, and air pump 3046, the compressed raw material can be quickly pelletized by reciprocating cutting. After pelletizing, the pelletized raw material is separated and transported along a designated path by blowing air through a single hole. Compared with the current dispersive pelletizing method, there is no breakage of the pellets, which can ensure the integrity of the pellets to the greatest extent and avoid the generation of a large number of compressed fragments.

[0060] As one embodiment of the present invention, such as Figure 4 , Figure 8 and Figure 9 As shown, a return material ramp 1012 is provided on the upper part of the tank body 101 and on the same side as the material nozzle 1011. The port of the return material ramp 1012 is connected to the straight return material channel 1013 inside the wall of the tank body 101. The straight return material channel 1013 extends downward along the wall of the tank body 101 to the material collection pipe 103 and is connected to the inclined channel inside the material collection pipe 103. A mesh plate 1015 is integrally provided inside the straight return material channel 1013 near the inclined channel. A finished product outlet 1014 extending inward is provided on the side of the tank body 101 at the position corresponding to the forming structure 3. The finished product outlet 1014 has a pointed protrusion on the upper surface of part of the tube inside the straight return material channel 1013, and the width of the tube is smaller than the width of the straight return material channel 1013.

[0061] The bottom of the pelletizing tube 304 of the tube body is provided with a through discharge port, and a lifting groove is provided at the input end of the sliding channel 3012 directly below the discharge port. A drop plate 305 is slidably arranged inside the lifting groove. Several lifting springs 3053 are integrally connected to both sides of the bottom surface of the drop plate 305, and are movably limited inside the lifting groove by the lifting springs 3053. Several equidistant connecting rods 3051 are integrally connected to the middle position of the ground of the drop plate 305, and one end of the connecting rod 3051 extends into the interior of the straight return channel 1013 and is fixed to the diamond cone spike frame 3052 at the lower end. The lifting springs 3053 are suspended directly above the mesh plate 1015, and there is sufficient gap between each cone spike.

[0062] During operation, after the raw material ball is fed into the feed chute 3012, it first lands on the surface of the drop plate 305. Under the gravity of the raw material ball, the drop plate 305 moves downward along the bottom lifting spring 3053. The downward-moving lifting spring 3053 simultaneously drives the connecting rod 3051 and the diamond-shaped cone spike bracket 3052 to move downward. The downward-moving diamond-shaped cone spike bracket 3052 will insert into the mesh of the mesh plate 1015. After the raw material ball rolls over, the drop plate 305 will return to its original position under the action of the lifting spring 3053. This process is performed after each cutting of the raw material ball. The cut raw material pad continues to be conveyed upwards and enters the return chute 1012 along the chute 3011. It then falls into the straight return chute 1013 along the return chute 1012 and then falls onto the surface of the screen plate 1015 along the straight return chute 1013 via the diamond cone spike frame 3052. If there are large blocks, the up-and-down moving diamond cone spike frame 3052 will crush the blocks. Then the raw material will pass through the screen plate 1015 and be conveyed back to the top of the collection pipe 103 along the opened channel to participate in the granulation operation again.

[0063] In summary, by configuring the tank 101, return inclined chute 1012, straight return chute 1013, mesh plate 1015, mounting component 301, material trough 3011, sliding chute 3012, drop plate 305, connecting rod 3051, diamond cone spike frame 3052, and lifting spring 3053, the pressed raw material after pelletizing can be lowered and recycled. Then, by utilizing the downward force generated during continuous granulation and the elastic effect of the lifting spring 3053, the diamond cone spike frame 3052 is driven up and down reciprocally. During the reciprocating motion, the recycled raw material below is crushed and guided downward, preventing large pieces of raw material from affecting the granulation process. Compared with current environmentally friendly de-icing agent production equipment, it does not produce a large amount of raw material debris and fragments, and the corresponding recycling step can be eliminated, greatly improving the efficiency of environmentally friendly de-icing agent production and reducing the workload generated during granulation.

[0064] This application also discloses a method for preparing an environmentally friendly de-icing agent, the specific steps of which are as follows:

[0065] S1. First, the premixed raw materials are fed into the feed nozzle 1011 via the conveyor belt. Then, the raw materials slide into the tank 101 from the feed nozzle 1011 and fall above the base 102. Then, the lifting screw 2 driven by the external drive device will spirally upload the raw materials and transfer them to the upper part of the collection pipe 103 for accumulation.

[0066] S2. The raw material accumulated above the collecting pipe 103 will be pressed into a pad with spherical protrusions on the surface by the granulating roller 302 driven by the external equipment, and conveyed upward to the conveying rollers 303. With the assistance of the conveying rollers 303, it will be conveyed to the pelletizing pipes 304.

[0067] S3. When the pressed raw material pad is conveyed to the pelletizing tubes 304, the rapidly rotating internal roller 3041 drives the cam 3042 to push the output end of the spring rod 3043 to slide out of the spring tube, and at the same time pushes the cutting tube 3044 to move closer to the spherical protrusion on the surface of the raw material pad along the pelletizing tube 304 until the cutting tube 3044 cuts together at the spherical protrusion, completing the separation of the spherical protrusion from the raw material pad. Then the air pump 3046 blows air into the blowhole 3045, and the cut spherical raw material will roll into the pelletizing tube 304 along the cutting tube 3044 under the action of the gas, and fall into the sliding channel 3012 from the material port on the lower side of the pelletizing tube 304, and be output from the finished product outlet 1014 along the sliding channel 3012. At this time, the output raw material spheres basically do not contain raw material debris.

[0068] S4. When the raw material ball is fed into the slide channel 3012, it will first fall on the surface of the drop plate 305. Under the gravity of the raw material ball, the drop plate 305 will move down along the bottom lifting spring 3053. The moving lifting spring 3053 will simultaneously drive the connecting rod 3051 and the diamond cone spike bracket 3052 to move down. The moving diamond cone spike bracket 3052 will insert into the mesh of the mesh plate 1015. After the raw material ball rolls over, the drop plate 305 will reset under the action of the lifting spring 3053. This process will be performed after each cutting of the raw material ball.

[0069] S5. The cut raw material pad will continue to be conveyed upward and enter the interior of the return chute 1012 along the chute 3011. It will then fall into the straight return channel 1013 along the return chute 1012 and then fall onto the surface of the screen plate 1015 along the straight return channel 1013 via the diamond cone spike frame 3052. If there are large blocks, the up-and-down moving diamond cone spike frame 3052 will crush the blocks. Then the raw material will pass through the screen plate 1015 and be conveyed back to the top of the collection pipe 103 along the opened channel to participate in the granulation operation again.

9. A method for preparing an environmentally friendly de-icing agent, using the environmentally friendly de-icing agent production equipment according to any one of claims 1-8, wherein the specific steps are as follows: S1. First, the premixed raw material is fed into the feed nozzle (1011) via the conveyor belt. Then, it slides into the tank (101) from the feed nozzle (1011) and falls above the base (102). Then, the lifting screw (2) driven by the external drive device will spirally upload the raw material and transfer it to the upper part of the collection pipe (103) for accumulation. S2. The raw material accumulated above the collecting pipe (103) will be pressed into a pad with spherical protrusions on the surface by the granulating roller (302) driven by the external equipment, and conveyed upward to the conveying rollers (303), and conveyed to the pelletizing pipes (304) with the assistance of the conveying rollers (303). S3. When the pressed raw material pad is conveyed to the pelletizing tube (304), the rapidly rotating internal roller (3041) will drive the cam (3042) to push the output end of the spring rod (3043) to slide out from the spring tube, and at the same time push the cutting tube (3044) to approach the spherical protrusion on the surface of the raw material pad along the pelletizing tube (304) until the cutting tube (3044) cuts together at the spherical protrusion, completing the separation of the spherical protrusion from the raw material pad. Then the air pump (3046) will blow air into the blow hole (3045), and the cut spherical raw material will roll into the pelletizing tube (304) along the cutting tube (3044) under the action of the gas, and fall into the sliding channel (3012) from the material port on the lower side of the pelletizing tube (304), and be output from the finished product outlet (1014) along the sliding channel (3012). At this time, the output raw material spheres basically do not contain raw material debris. S4. When the raw material ball is fed into the feed chute (3012), it will first fall onto the surface of the drop plate (305). Under the gravity of the raw material ball, the drop plate (305) will move down along the bottom lifting spring (3053), and the moving lifting spring (3053) will simultaneously drive the connecting rod (3051) and the diamond cone spike holder (3052) to move down. The downward-moving diamond-shaped cone spike (3052) will insert into the mesh of the mesh plate (1015). After the raw material ball rolls over, the drop plate (305) will be reset under the action of the lifting spring (3053). This process will be performed after each cutting of the raw material ball. S5. The cut raw material pad will continue to be conveyed upward and enter the interior of the return chute (1012) along the chute (3011). It will fall into the straight return chute (1013) along the return chute (1012) and then fall onto the surface of the screen plate (1015) along the straight return chute (1013) through the diamond cone spike frame (3052). If there are large blocks, the up-and-down moving diamond cone spike frame (3052) will crush the blocks. Then the raw material will pass through the screen plate (1015) and be conveyed back to the top of the collection pipe (103) along the opened channel to participate in the granulation operation again.
