Description

Technical Field

[0001] The invention relates to the technical field of nylon filament production, and in particular to a chip conveying pipeline for producing nylon filament based on chemical recycling. Background Art

[0002] Chips are the main raw material for the production of functional nylon filaments. During the production process, the chips are transported in pipelines by compressed air. Depending on the flow of the chips in the pipeline, they are divided into continuous conveying and pulse conveying. Traditional conveying components are prone to certain problems during the conveying process of the chips.

[0003] Patent announcement number CN214826347U discloses a chip conveying pipeline for nylon filament production, comprising a plurality of pipe monomers connected together by flanges, a metal clamp provided on the pipe monomer, the metal clamp having two clamping feet, a screw rod 1 passing through the two clamping feet, a nut 1 provided at the end of the screw rod 1; the screw rod 1 is hollow, a screw rod 2 is passed through the screw rod 1, a ring piece and a nut 2 are provided at the end of the screw rod 2, and an electrostatic conductor is connected to the ring piece; a protective cover is provided at the screw head end of the screw rod 1. This patent avoids the exposure of the connection point between the electrostatic conductor and the ring piece by providing a screw rod 2 passing through the screw rod 1 and a matching nut 2, placing the ring piece at the screw head end of the screw rod 1, and providing a protective cover, thereby effectively reducing corrosion, making it less prone to damage, ensuring the electrostatic conductor's static electricity conduction effect, and effectively conducting away the static electricity generated by the chips during the conveying process, preventing a large amount of dust from accumulating on the pipe wall, and ensuring spinning performance.

[0004] However, this device still has some shortcomings: the device can conduct away the static electricity generated by the slices when they are transported in the pipeline, but the nylon slice raw materials are prone to mutual adhesion and aggregation when stored under the influence of the high temperature in summer and the humid environment in the rainy season. Therefore, it is difficult for the device to break up the slices during the pipeline transportation of the slices, resulting in some slices that have aggregated into blocks being directly transported to the next nylon filament production process, which has a certain adverse effect on the production of nylon filament. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a chip conveying pipeline for producing nylon filaments based on chemical recycling, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a chip conveying pipeline for the production of nylon filaments based on chemical recycling, comprising a conveying pipe, a conveying component is built into the conveying pipe, a supporting component is provided at the bottom of the outer wall of the conveying pipe, and the supporting component is fixedly connected to the conveying pipe through a metal clamp, a conductive wire is provided inside the supporting component, and the conductive wire is connected to the conveying pipe, a feed box is provided on the left side of the conveying pipe, a motor is provided at the bottom of the feed box, a cooling component is provided on the left side of the feed box, the cooling component is connected to the feed box, and the feed A baffle is provided on the right side of the inner wall of the material box, and a plurality of filter holes are provided on the surface of the baffle, and the baffle is located between the right side of the feed box and the left side of the delivery pipe. A rotating rod is rotatably installed at the center of the bottom of the inner wall of the feed box, and a reciprocating spiral groove is provided above the outer wall of the rotating rod, and the bottom of the rotating rod passes through and is fixedly installed on the top of the output end of the motor, and a collar is passed through and slidably installed on the outer wall of the rotating rod, and the inner wall of the collar contacts the reciprocating spiral groove of the outer wall of the rotating rod, and a sieve plate is fixedly installed on the outer wall of the collar, and a plurality of U-shaped plates are equidistantly and fixedly installed above the outer wall of the rotating rod, and the vertical surfaces of the inner walls of the plurality of U-shaped plates are A round rod is rotatably installed, and a spiral sheet is fixedly installed on the outer wall of the round rod. A friction plate is fixedly installed at the bottom of the inner wall of the sieve plate near the outer wall of the sleeve. The feed pipe is connected to the round hole on the top of the feed box, and the inside of the feed box is transported at a low temperature through the cooling component to keep the temperature inside the feed box low, and the internal conveying component of the conveying pipe is started at the same time; when the feed box starts to fall, the filter holes of the baffle are blocked to block the raw materials that adhere to each other and aggregate into blocks under the influence of the high temperature in summer and the humid environment in the rainy season. At the same time, the motor is started, and the output end of the motor drives the rotation The rod rotates, and when the rotating rod rotates, the collar is restricted by its own non-self-locking reciprocating spiral groove, and the built-in block of the collar contacts the inner wall of the reciprocating spiral groove on the outer wall of the rotating rod, so that the collar can slide up and down along the reciprocating spiral groove on the outer wall of the rotating rod, and the collar drives the screen plate to slide synchronously along the inner wall of the feed box; when the rotating rod rotates, it drives the U-shaped plate to rotate, and the rotation of the U-shaped plate drives the round rod to rotate. When the round rod makes a circular motion and the screen plate rises and drives the friction plate to rise synchronously, the outer wall of the round rod will resist the vertical surface of the friction plate to generate friction. At this time, the round rod starts to rotate due to friction, and the round rod drives the spiral piece to move synchronously.

[0007] According to the above technical solution, a number of sieve holes are provided on the surface of the sieve plate, and the vertical surface of the outer wall of the sieve plate is slidably installed on the vertical surface of the inner wall of the feed box. The right side of the sieve plate is in contact with the left side of the baffle, and the top arc surface of the friction plate is located on the motion trajectory of the bottom arc surface of the outer wall of the round rod. An anti-adhesion device is provided under the sieve plate for centrally collecting the dust falling from the nylon slice raw material to prevent the dust from splashing and adhering to the surface of the raw material for the second time.

[0008] According to the above technical solution, the anti-adhesion device includes a screw rod, a connecting rod and a collection box. The bottom of the screw rod is rotatably installed at the bottom of the inner wall of the feed box. The screw rod is located on the left side of the rotating rod, and an arc groove is opened on the outer wall of the screw rod. The top of the screw rod passes through the inside of the sieve plate, and the left side of the connecting rod is slidably installed inside the arc groove of the outer wall of the screw rod. The inner wall of the collection box is fixedly installed on the right side of the connecting rod, and the outer wall of the collection box is slidingly connected to the inner wall of the feed box. The collection box is located below the sieve plate. When the sieve plate moves upward and resets, the built-in block of the sieve plate reciprocates and contacts the non-self-locking spiral groove on the outer wall of the screw rod. The sliding contact of the sieve plate causes the screw rod to generate a rotational force and start to rotate. When the screw rod rotates, the restriction of the arc groove on the connecting rod causes the connecting rod to slide up and down inside the arc groove of the screw rod. The connecting rod drives the collection box to slide synchronously along the inner wall of the feed box, and so on.

[0009] According to the above technical solution, the anti-adhesion device also includes two U-shaped frames, several rotating wheels, a transmission rod, several curved plates and a swinging plate. The bottoms of the two U-shaped frames are hinged at the bottom edge of the inner wall of the collection box. The two U-shaped frames are symmetrically distributed around the axis of the collection box. Several of the rotating wheels are mounted on the outer wall of the U-shaped frame on the vertical side close to the center of the collection box. The curved surface of the outer wall of the wheel contacts the bottom surface of the sieve plate. The left and right ends of the transmission rod pass through and are fixedly mounted on the inner wall of the wheel. Several of the curved plates pass through and are slidably mounted on the outer wall surface of the transmission rod. The center of the outer wall of the swinging plate is hinged to the inside of the U-shaped frame through a torsion spring. When the collection box moves up and down The U-shaped frame is driven to move synchronously, and the U-shaped frame drives the runner to move synchronously, and the outer wall of the runner contacts the bottom of the sieve plate to generate friction, which causes the hinge shaft of the U-shaped frame to rotate. The U-shaped frame pushes the runner to move along the bottom of the sieve plate toward the center of the sieve plate. The outer wall of the runner contacts the bottom of the sieve plate to generate friction and start to rotate. When the runner rotates, it drives the transmission rod to rotate, and the transmission rod drives the arc plate to rotate and brush the bottom of the sieve plate. The spring setting causes the arc plate to always be close to the bottom of the sieve plate. At the same time, when the arc plate rotates, it will continuously conflict with the arc surface of the swing plate, causing the hinge shaft of the swing plate to rotate. At this time, the swing plate swings back and forth about its own center axis and swings to guide and dump the falling powder.

[0010] According to the above technical solution, a spring is arranged between the arc plate and the transmission rod, and the arc surface of the arc plate contacts the bottom of the screen plate. The top arc surface of the swing plate is located on the movement trajectory of the arc plate. An anti-mold device is provided under the collection box to disturb the internal gas circulation of the feed box to prevent mold growth due to a humid environment.

[0011] According to the above technical solution, the anti-mildew device includes several square frames, several disinfection plates and activated carbon plates. Several of the square frames are fixedly installed on the outer wall surface of the screw rod, and several of the disinfection plates are hinged inside the square frame at the centers of the upper and lower sides through torsion springs, and several of the disinfection plates are equidistantly distributed. Several ultraviolet lamps are provided on the outer wall of the disinfection plate. The bottom of the activated carbon plate is fixedly installed on the top of the square frame. When the screw rod rotates, it drives the square frame to rotate. The square frame drives the disinfection plate to rotate and quickly disturbs the accumulated gas inside the feed box. When the square frame rotates, it drives the activated carbon plate to rotate.

[0012] According to the above technical solution, the anti-mildew device also includes a sliding plate, a spring and a knocking column. The sliding plate is slidably installed on the inner wall of the activated carbon board away from the outer wall of the screw rod through a spring. The top of the sliding plate is located on the movement track of the bottom of the collecting box. The vertical surface of the spring is fixedly installed between the inner wall of the activated carbon board and the side of the sliding plate away from the inner wall of the activated carbon board. The knocking column is fixedly installed on the concave surface of the spring away from the sliding plate, and the knocking column is in contact with the inner wall of the activated carbon board at one end close to the sliding plate. When the collecting box moves downward, it resists the sliding plate and slides synchronously along the inner wall of the activated carbon board. The activated carbon board resists the spring sheet and is deformed. When the collecting box no longer resists the sliding plate, the sliding plate is reset by the elastic force of the spring sheet. Therefore, when the spring sheet is deformed, it drives the knocking column away from the activated carbon board. Then, when resetting, the spring sheet drives the knocking column to suddenly knock on the inner wall of the activated carbon board to cause vibration.

[0013] According to the above technical solution, the anti-mildew device also includes a U-shaped rod and a push plate. The top of the U-shaped rod is fixedly installed on the arc surface of the spring plate near the sliding plate, and the push plate is fixedly installed on the vertical surface of the bottom of the U-shaped rod near the square frame away from the square frame. The vertical surface of the push plate near the square frame is hinged to the arc surface of the disinfection plate. When the spring plate is deformed and reset, it drives the U-shaped rod to move to the left and reset, and the U-shaped rod drives the push plate to move synchronously. The push plate pulls the disinfection plate to swing along the inner wall of the square frame with its own hinge axis as the center of the circle.

[0014] The present invention provides a chip conveying pipeline for producing nylon filaments based on chemical recycling. It has the following beneficial effects:

[0015] (1) The present invention cooperates with the baffle, the rotating rod, the sleeve and the screen plate to prompt the baffle to block the agglomerated materials, and the falling raw materials fall onto the screen plate, and then the force of the up and down movement of the screen plate prompts the raw materials to be evenly distributed inside itself to avoid mutual accumulation, which causes the raw materials to be squeezed and increase the agglomeration area, and at the same time ensures that the conveying component can effectively pump and convey the raw materials for a long time; through the cooperation of the U-shaped plate, the round rod, the spiral sheet and the friction plate, the agglomerated raw materials are rotated and beaten, so that the agglomerated raw materials are dispersed by reducing the mutual adhesion strength through the beating force, prompting their own particle size to adhere to the processing process and be transported through the conveying component, avoiding the increase in raw material cost due to the accumulation of raw materials, and increasing economic benefits to a certain extent.

[0016] (2) The present invention sets an anti-adhesion device, and cooperates with the sieve plate, the screw rod, the connecting rod and the collecting box to prompt the collecting box to collect the raw material powder that falls from the bottom of the sieve plate due to the sieving of the raw materials, and the up and down movement of the collecting box prompts the powder to be evenly shaken and distributed inside the collecting box, thereby preventing the maintenance cycle of the collecting box by the staff from being too long, resulting in secondary overflow of the powder and flying and adhering to the surface of the raw materials, affecting the later processing, and avoiding the long-term adhesion and erosion of the raw materials transported inside the pipeline by the foam, thereby reducing the service life of the pipeline; through the cooperation of the U-shaped frame, the rotating wheel, the transmission rod, the arc plate and the swing plate, the small amount of powder attached to the bottom of the sieve plate is swept and dropped into the collecting box to ensure the cleanliness of the sieve plate and avoid erosion caused by the corrosiveness of the raw materials; at the same time, when the arc plate is brushed, the raw materials stuck in the sieve hole of the sieve plate are rotated and picked upwards, thereby preventing the sieve hole of the sieve plate from being blocked and causing the powder to be difficult to fall, and the up and down swing of the swing plate seals the air-raising powder to prevent the powder from floating around.

[0017] (3) The present invention uses the setting of the anti-mildew device, and cooperates with the screw rod, square frame, disinfection plate and activated carbon plate to evenly evacuate and distribute the cold air transported by the cooling component to the internal space of the collection box, shortening the cooling speed inside the collection box, avoiding the softening of the raw materials caused by the excessive temperature generated by the operation of the equipment, and the deformation of the raw materials after being squeezed to reduce their individual integrity. At the same time, the activated carbon plate absorbs and rotates the harmful gases emitted by the material due to high temperature; through the cooperation of the sliding plate, spring, knocking column, U-shaped rod and push plate, the swing plate is caused to vibrate synchronously through the transmission of force, and the swing plate relies on the vibration force to reduce the adhesion area of ​​the powder on its own inclined surface; and the disinfection plates are superimposed on each other to form a seal with the square frame, thereby accelerating the fanning effect of the cold air, and at the same time expanding the irradiation range of the ultraviolet lamp, improving the sterilization effect inside the feed box, and avoiding moisture causing mold growth, thereby affecting the later transportation of raw materials.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figures 1-9One embodiment of the present invention is: a chip conveying pipeline for the production of nylon filaments based on chemical recycling, comprising a conveying pipe 1, a conveying component built into the conveying pipe 1, a support component 2 provided at the bottom of the outer wall of the conveying pipe 1, and the support component 2 is fixedly connected to the conveying pipe 1 through a metal clamp, a conductive wire 21 is provided inside the support component 2, and the conductive wire 21 is connected to the conveying pipe 1, a feed box 3 is provided on the left side of the conveying pipe 1, a motor is provided at the bottom of the feed box 3, a cooling component 31 is provided on the left side of the feed box 3, and the cooling component 31 is connected to the feed box 3, the feed box 3 is provided with a baffle 6 on the right side of the inner wall, and a plurality of filter holes are opened on the surface of the baffle 6, and the baffle 6 is located between the right side of the feed box 3 and the left side of the delivery pipe 1. A rotating rod 7 is rotatably installed at the center of the bottom of the inner wall of the feed box 3. A reciprocating spiral groove is opened on the upper part of the outer wall of the rotating rod 7, and the bottom of the rotating rod 7 passes through and is fixedly installed on the top of the motor output end. A collar 8 is passed through and slidably installed on the outer wall of the rotating rod 7. The inner wall of the collar 8 contacts the reciprocating spiral groove on the outer wall of the rotating rod 7. A sieve plate 9 is fixedly installed on the outer wall of the collar 8. A plurality of U-shaped plates 10 are equidistantly and fixedly installed on the upper part of the outer wall of the rotating rod 7. The vertical surface of the inner wall of the shaped plate 10 is rotatably installed with a round rod 11, and the outer wall of the round rod 11 is fixedly installed with a spiral sheet 12. The bottom of the inner wall of the sieve plate 9 is fixedly installed near the outer wall of the ring 8. The raw materials falling into the feed box 3 are pulled by the suction of the conveying component and conveyed to the next processing step. Since the nylon slices inevitably rub against the inner wall of the conveying pipe 1 during the conveying process to generate static electricity, the static electricity is conducted to the support component 2 through the conductive wire 21, and then conducted to the ground by the support component 2; through the above cooperation, the baffle 6 is prompted to block the agglomerated materials, and the falling The raw materials below fall onto the sieve plate 9, and the force of the up and down movement of the sieve plate 9 causes the raw materials to be evenly distributed inside itself to avoid mutual accumulation, which causes the raw materials to be squeezed each other and increases the agglomeration area, while ensuring that the conveying component can effectively pump and convey the raw materials for a long time; through the above cooperation, the agglomerated raw materials are rotated and slapped, so that the agglomerated raw materials reduce the mutual adhesion strength through the slapping force and thus disperse, causing their own particle size to adhere to the processing process and be conveyed through the conveying component, avoiding the increase in raw material cost due to the accumulation of raw materials, and increasing economic benefits to a certain extent.

[0030] A number of sieve holes are provided on the surface of the sieve plate 9, and the vertical surface of the outer wall of the sieve plate 9 is slidably installed on the vertical surface of the inner wall of the feed box 3. The right side of the sieve plate 9 contacts the left side of the baffle 6, and the top arc surface of the friction plate 13 is located on the motion trajectory of the bottom arc surface of the outer wall of the round rod 11. An anti-adhesion device 4 is provided below the sieve plate 9 for collecting the dust falling from the nylon slice raw material to prevent the dust from splashing and adhering to the surface of the raw material for the second time.

[0031] When in use, the feeding pipe is connected to the circular hole on the top of the feed box 3, and the inside of the feed box 3 is transported at a low temperature by the cooling component 31 to keep the internal temperature of the feed box 3 low. At the same time, the conveying component inside the conveying pipe 1 is started, and the raw materials falling into the feed box 3 are pulled by the suction of the conveying component and conveyed to the next processing step. Since the nylon slices inevitably rub against the inner wall of the conveying pipe 1 during the transportation process to generate static electricity, the static electricity is conducted to the support component 2 through the conductive wire 21, and then conducted to the ground by the support component 2; when the feed box 3 starts to fall, the filter holes of the baffle 6 are blocked to block the raw materials that adhere to each other and aggregate into blocks under the influence of the high temperature in summer and the humid environment in the rainy season. At the same time, the motor is started, and the output end of the motor drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, the non-self-locking reciprocating spiral groove of the rotating rod 7 restricts the ring 8, and the built-in block of the ring 8 contacts the inner wall of the reciprocating spiral groove on the outer wall of the rotating rod 7, so that the ring 8 can slide up and down along the reciprocating spiral groove on the outer wall of the rotating rod 7, and the ring 8 drives the screen The plate 9 slides synchronously along the inner wall of the feed box 3, and the above cooperation prompts the baffle 6 to block the agglomerated materials, and the fallen materials fall to the screen plate 9, and then the force of the up and down movement of the screen plate 9 prompts the materials to be evenly distributed inside itself to avoid mutual accumulation, which causes the materials to be squeezed each other and increases the agglomeration area, while ensuring that the conveying assembly can effectively pull and convey the materials for a long time; when the rotating rod 7 rotates, it drives the U-shaped plate 10 to rotate, and the rotation of the U-shaped plate 10 drives the round rod 11 to rotate. When the round rod 11 performs a circular motion and the screen plate 9 rises and drives the friction plate 13 to rise synchronously, the outer wall of the round rod 11 will resist the vertical surface of the friction plate 13 to generate friction. At this time, the round rod 11 starts to rotate by friction, and the round rod 11 drives the spiral sheet 12 to move synchronously. Through the above cooperation, the rotation and slapping of the agglomerated materials are achieved, so that the agglomerated materials are reduced in mutual adhesion strength by the slapping force, thereby dispersing, prompting their own particle size to adhere to the processing process and be transported by the conveying assembly, avoiding the increase in raw material cost due to the accumulation of raw materials, and increasing the economic benefit to a certain extent.

[0032] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-adhesion device 4;

[0033] The anti-adhesion device 4 includes a screw rod 41, a connecting rod 42 and a collection box 43. The bottom of the screw rod 41 is rotatably installed on the bottom of the inner wall of the feed box 3. The screw rod 41 is located on the left side of the rotating rod 7, and an arc groove is opened on the outer wall of the screw rod 41. The top of the screw rod 41 passes through the inside of the sieve plate 9, and the left side of the connecting rod 42 is slidably installed in the arc groove on the outer wall of the screw rod 41. The inner wall of the collection box 43 is fixedly installed on the right side of the connecting rod 42, and the outer wall of the collection box 43 is slidably connected to the inner wall of the feed box 3. The collection box 43 is located below the sieve plate 9. Through the above cooperation, the collection box 43 is prompted to collect the raw material powder that falls from the bottom of the sieve plate 9 due to screening of the raw materials, and the up and down movement of the collection box 43 prompts the powder to shake evenly and be distributed inside the collection box 43, preventing the staff from maintaining the collection box 43 for too long, resulting in secondary overflow and flying of the powder and adhering to the surface of the raw material, affecting the later processing, and avoiding the long-term adhesion and erosion of the raw materials transported in the pipeline 1 by the floating foam, thereby reducing the service life of the pipeline 1.

[0034] The anti-adhesion device 4 also includes two U-shaped frames 44, a number of runners 45, a transmission rod 46, a number of curved plates 47 and a swing plate 48. The bottoms of the two U-shaped frames 44 are hinged at the bottom edge of the inner wall of the collection box 43. The two U-shaped frames 44 are symmetrically distributed around the axis of the collection box 43. A number of runners 45 are mounted on the outer wall of the U-shaped frame 44 near the center of the collection box 43. The arc surface of the outer wall of the runner 45 contacts the bottom surface of the sieve plate 9. The left and right ends of the transmission rod 46 pass through and are fixedly mounted on the inner wall of the runner 45. A number of curved plates 47 are mounted on the outer wall of the U-shaped frame 44. It penetrates and slides on the outer wall surface of the transmission rod 46, and the center of the outer wall of the swing plate 48 is hinged to the inside of the U-shaped frame 44 through a torsion spring. In this way, a small amount of powder attached to the bottom of the sieve plate 9 is swept and dropped into the collection box 43 to ensure the cleanliness of the sieve plate 9 and avoid erosion caused by corrosive raw materials; at the same time, when the arc plate 47 is brushed, the raw materials stuck in the sieve holes of the sieve plate 9 are rotated and picked upward to prevent the sieve holes of the sieve plate 9 from being blocked, which makes it difficult for the powder to fall, and the up and down swinging of the swing plate 48 seals the air-raising powder to prevent the powder from floating around.

[0035] A spring is provided between the arc plate 47 and the transmission rod 46, and the arc surface of the arc plate 47 contacts the bottom of the screen plate 9. The top arc surface of the swing plate 48 is located on the movement trajectory of the arc plate 47. An anti-mold device 5 is provided under the collection box 43 for disturbing the internal gas circulation of the feed box 3 to prevent mold growth due to a humid environment.

[0036] When in use, when the sieve plate 9 moves upward and resets, the built-in block of the sieve plate 9 reciprocates and contacts the non-self-locking spiral groove on the outer wall of the screw rod 41, and the sliding contact of the sieve plate 9 causes the screw rod 41 to generate a rotating force and start to rotate. When the screw rod 41 rotates, the arc groove restricts the connecting rod 42, causing the connecting rod 42 to slide up and down inside the arc groove of the screw rod 41, and the connecting rod 42 drives the collecting box 43 to slide synchronously along the inner wall of the feed box 3, and so on. Through the above cooperation, the collecting box 43 is prompted to collect the raw material powder that falls from the bottom of the sieve plate 9 due to the sieving of the raw materials. The collection box 43 is collected and the up and down movement of the collecting box 43 causes the powder to be evenly shaken and distributed inside the collecting box 43, preventing the maintenance cycle of the collecting box 43 by the staff from being too long, causing the powder to overflow and fly again and adhere to the surface of the raw materials to affect the later processing, and avoiding the raw materials transported inside the conveying pipe 1 from being adhered to and eroded by foam for a long time, thereby reducing the service life of the conveying pipe 1; when the collecting box 43 moves up and down, it drives the U-shaped frame 44 to move synchronously, and the U-shaped frame 44 drives the runner 45 to move synchronously, and the outer wall of the runner 45 contacts the bottom of the sieve plate 9 to generate resistance The contact causes the hinge shaft of the U-shaped frame 44 to rotate, and the U-shaped frame 44 pushes the runner 45 to move along the bottom of the sieve plate 9 toward the center of the sieve plate 9. The outer wall of the runner 45 contacts the bottom of the sieve plate 9 to generate friction and start to rotate. When the runner 45 rotates, it drives the transmission rod 46 to rotate, and the transmission rod 46 drives the arc plate 47 to rotate and brush the bottom of the sieve plate 9. The setting of the spring causes the arc plate 47 to always be close to the bottom of the sieve plate 9. At the same time, when the arc plate 47 rotates, it will continuously resist the arc surface of the swing plate 48 to cause the hinge shaft of the swing plate 48 to rotate. At this time, the swing plate 48 swings back and forth about its own central axis and swings to guide and dump the falling powder, so that a small amount of powder attached to the bottom of the sieve plate 9 is swept and falls into the collection box 43 to ensure the cleanliness of the sieve plate 9 and avoid erosion caused by corrosive raw materials; at the same time, when the arc plate 47 brushes, the raw materials stuck in the sieve holes of the sieve plate 9 are rotated and picked upwards to prevent the sieve holes of the sieve plate 9 from being blocked, which makes it difficult for the powder to fall, and the up and down swinging of the swing plate 48 seals the air-raising powder to prevent the powder from floating around.

[0037] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-mildew device 5;

[0038] The anti-mildew device 5 includes several square frames 51, several disinfection plates 52 and activated carbon plates 53. The several square frames 51 are fixedly installed on the outer wall surface of the screw rod 41, and the centers of the upper and lower sides of the several disinfection plates 52 are hinged to the inside of the square frame 51 through torsion springs, and the several disinfection plates 52 are equidistantly distributed. The outer wall of the disinfection plate 52 is provided with several ultraviolet lamps, and the bottom of the activated carbon plate 53 is fixedly installed on the top of the square frame 51. Through the above cooperation, the cold air delivered by the cooling component 31 is evenly evacuated and distributed to the internal space of the collection box 43, shortening the cooling speed inside the collection box 43, avoiding the high temperature generated by the operation of the equipment, causing the raw materials to soften, and the raw materials to be deformed after being squeezed and reduce their individual integrity. At the same time, the activated carbon plate 53 absorbs and rotates the harmful gases emitted by the material due to high temperature, avoiding the long-term accumulation and fermentation of harmful gases, which increases the risk to the health of the maintenance personnel in the later stage.

[0039] The anti-mold device 5 also includes a sliding plate 54, a spring 55 and a knocking column 56. The sliding plate 54 is slidably installed on the inner wall of the activated carbon plate 53 on the side away from the outer wall of the screw rod 41 through a spring. The top of the sliding plate 54 is located on the movement trajectory of the bottom of the collection box 43. The vertical surface of the spring 55 is fixedly installed between the inner wall of the activated carbon plate 53 and the side of the sliding plate 54 away from the inner wall of the activated carbon plate 53. The knocking column 56 is fixedly installed on the concave surface of the spring 55 at one end away from the sliding plate 54, and the knocking column 56 is in contact with the inner wall of the activated carbon plate 53 at one end close to the sliding plate 54. Through the above cooperation, the friction force of the sliding plate 54 is relied on to accelerate the volatilization speed of the purification factor in the activated carbon plate 53, thereby improving the purification speed of harmful gases. At the same time, the swing plate 48 is caused to vibrate synchronously through the transmission of force, and the swing plate 48 relies on the vibration force to reduce the adhesion area of ​​the powder on its own inclined surface.

[0040] The anti-mildew device 5 also includes a U-shaped rod 57 and a push plate 58. The top of the U-shaped rod 57 is fixedly installed on the arc surface of the spring piece 55 near the sliding plate 54. The push plate 58 is fixedly installed on the vertical surface of the bottom of the U-shaped rod 57 near the square frame 51 away from the square frame 51. The vertical surface of the push plate 58 near the square frame 51 is hinged to the arc surface of the disinfection plate 52. Through the above cooperation, the disinfection plates 52 are superimposed on each other when they swing to form a seal with the square frame 51, thereby accelerating the fanning effect of the cold air, and the reciprocating swing of the disinfection plate 52 drives the synchronous movement of the ultraviolet lamp to expand the irradiation range of the ultraviolet lamp, thereby improving the sterilization effect on the inside of the feed box 3 and avoiding moisture causing mold growth, thereby affecting the later transportation of raw materials.

[0041] When in use, the screw rod 41 rotates and drives the square frame 51 to rotate, and the square frame 51 drives the disinfection plate 52 to rotate and quickly disturbs the gas accumulated inside the feed box 3. The square frame 51 rotates and drives the activated carbon plate 53 to rotate. Through the above cooperation, the cold air delivered by the cooling component 31 is evenly evacuated and distributed to the internal space of the collection box 43, shortening the cooling speed inside the collection box 43, avoiding the excessive temperature generated by the operation of the equipment, which causes the raw materials to soften, and the raw materials to be deformed after being squeezed and reduce their individual integrity. At the same time, the activated carbon plate 53 absorbs and rotates the harmful gases emitted by the material due to high temperature, avoiding the long-term accumulation and fermentation of harmful gases, which increases the risk to the health of later maintenance personnel; when the collection box 43 moves downward, it resists the sliding plate 54 and slides synchronously along the inner wall of the activated carbon plate 53, and the activated carbon plate 53 resists the shrapnel 55 and is deformed. When the collection box 43 no longer resists the sliding plate 54, the sliding plate 54 is reset by the elastic force of the shrapnel 55, and the shrapnel 55 drives the knocking column when it is deformed. 56 is away from the activated carbon plate 53, and then when it is reset, the spring piece 55 drives the knocking column 56 to suddenly knock the inner wall of the activated carbon plate 53 to cause vibration. Through the above cooperation, the friction force of the sliding plate 54 is used to accelerate the volatilization speed of the purification factor in the activated carbon plate 53, thereby improving the purification speed of harmful gases. At the same time, the swing plate 48 is prompted to vibrate synchronously through the transmission of force, and the swing plate 48 relies on the vibration force to reduce the adhesion area of ​​the powder on its own inclined surface; when the spring piece 55 is deformed and reset, it drives the U-shaped rod 57 to move left and reset, and the U-shaped rod 57 drives the push plate 58 to move synchronously, and the push plate 58 pulls the disinfection plate 52 to swing along the inner wall of the square frame 51 with its own hinge axis as the center of the circle. Through the above cooperation, the disinfection plates 52 are superimposed on each other when they swing to form a seal with the square frame 51, thereby accelerating the fanning effect of the cold air, and the reciprocating swing of the disinfection plate 52 drives the synchronous movement of the ultraviolet lamp, thereby expanding the irradiation range of the ultraviolet lamp, thereby improving the sterilization effect inside the feed box 3 and avoiding moisture causing mold growth, thereby affecting the later transportation of raw materials.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
