Description

Technical Field

[0001] This utility model belongs to the field of yam powder puffing processing technology, specifically relating to a puffing system for preventing clogging of powder materials. Background Technology

[0002] When yam powder is puffed in an extruder, it is first fed into the high-level feed port of the extruder through a powder material feeding device. After puffing inside the extruder, the yam powder is discharged from the die head outlet. A significant amount of moisture is generated on the outside of the die head. The extruder is equipped with a rotary cutting device at the die head outlet. To ensure safety, a stainless steel protective cover is installed outside the rotary cutting device, completely enclosing it. The cover also serves to prevent the puffed balls (small pieces of yam powder extruded and then rotary-cut into puffed balls) from splashing around and falling into the receiving hopper directly below. A blower is located on the side of the receiving hopper. The puffed balls are blown by the blower and flow along the air feed pipe into the unloader, and then fall into the cooling air bed. Existing powder material feeding devices and extruders have the following shortcomings or deficiencies in actual production:

[0003] (1) The existing anti-bridging feeding device for powder materials includes a support frame, on which a storage silo and a screw feeder are mounted. The screw feeder is tilted with the left side lower than the right side. A diagonal brace is provided between the bottom right side of the support frame and the right side of the screw feeder. The lower end of the storage silo is connected to the upper left feed port of the screw feeder. For powder materials with good flowability, a circular silo is used. For yam powder with a certain viscosity and slightly poor flowability, a storage silo with a rectangular cross-section and an overall four-sided pyramid shape is preferred. The lower end of the storage silo is a square discharge port with the same diameter as the screw shaft of the screw feeder. Since yam powder has a certain viscosity, the slope of the four side panels of the storage silo is the same. The large slope length of the side panels has a large flow resistance to the yam powder. Furthermore, inside the storage silo, the accumulation and weight of the powder cause the yam powder inside the silo to be compacted, resulting in poorer flowability. If a vibration device is used to vibrate the silo wall, the flowability will be even worse, often resulting in arching or rat holes. The powder, especially the powder at the silo wall, cannot flow out smoothly and accumulates thicker and thicker, affecting the smooth discharge. Often, the material at the silo wall is pushed to the center of the silo manually, which is not only a waste of manpower but also unsanitary.

[0004] (2) A dehumidification pipe is installed on the upper part of the outer cover of the extrusion die head. The moisture generated outside the extrusion port condenses when it encounters the metal cover. Water droplets fall into the receiving hopper, causing the extruded balls to clump together. The moisture in the clumps cannot be released under the cooling air bed. It will clog the screen in the crusher after entering the extruder. In severe cases, the sticky and wet extruded ball clumps will adhere to the inner wall of the receiving hopper or the air conveying pipe, and even block the air conveying channel. Therefore, the moisture in the cover must be discharged in time and smoothly. Common dehumidification devices have a round hole on the top of the cover. A dehumidification filter plate and an exhaust pipe are installed on the round hole. The exhaust pipe is connected to the exhaust fan with a hose. This dehumidification device has a simple structure, but because the moisture contains a lot of sticky particles, it will adhere to the plate between the vent holes of the filter plate. After accumulation, it will block the vent holes, reduce the dehumidification effect, and make it difficult to discharge the moisture, which cannot guarantee continuous extrusion production. If the filter plate is cleaned, the machine needs to be stopped, which will affect the production efficiency. Utility Model Content

[0005] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a powder material anti-clogging puffing system that prevents the storage bin from arching, ensures continuous and uniform material supply, promptly extracts moisture generated by the puffing balls, and allows for the replacement of clogged filter plates without stopping the machine.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a powder material anti-clogging puffing system, including a powder material feeding device and an puffing machine. The powder material feeding device is located on the left side of the puffing machine. The top of the puffing machine is provided with a feed inlet. The feed port of the powder material feeding device is connected to the feed inlet of the puffing machine. The discharge port of the mold head on the right side of the puffing machine is provided with a top-and-bottom transparent protective cover. The upper end of the protective cover is connected to a top-and-bottom transparent square tube. The upper end of the square tube is connected to a dehumidifying pipe. The outlet of the dehumidifying pipe is connected to a dehumidifying fan. The square tube is provided with an upper drawer-type filter assembly and a lower drawer-type filter assembly that are horizontally pushed and pulled in the front-and-back direction.

[0007] The front side wall of the square tube has an upper rectangular opening for the upper drawer-type filter assembly to pass through and a lower rectangular opening for the lower drawer-type filter assembly to pass through. The upper and lower drawer-type filter assemblies have the same structure and are arranged at intervals.

[0008] Both the upper and lower drawer-type filter components include a rectangular frame that is open at the top and bottom. The left and right sides of the inner wall of the square tube are provided with support guide strips for supporting the back-and-forth sliding of the rectangular frame. A handle is provided on the front side of the rectangular frame. Support strips are provided on the rear, left and right sides of the inner wall of the rectangular frame. The upper side of the three support strips is lower than the upper side of the lower rectangular frame. A wave filter plate is placed on the three support strips inside the rectangular frame.

[0009] The vertical cross-section of the corrugated filter plate is wavy in the left-right direction. Several air vents are provided on the corrugated filter plate, which are located in the lower middle part of the corrugated filter plate.

[0010] The front panel of the rectangular frame has a larger area than the rectangular opening, and the rear side of the front panel of the rectangular frame is provided with a sealing strip that fits and contacts the front side of the square tube.

[0011] The powder material feeding device includes a support frame, on which a storage silo and a screw conveyor are mounted. The screw conveyor is inclined from left to right, with a lower left side and a higher right side. A diagonal brace is located between the bottom right side of the screw conveyor and the right side of the support frame. The storage silo includes a left triangular plate, a right triangular plate, a front upper triangular plate, a front lower triangular plate, a rear upper triangular plate, and a rear lower triangular plate. The left triangular plate is inclined from left to right, and the right triangular plate is inclined from left to right. The front side of the left triangular plate is connected to the left side of the front lower triangular plate, and the rear side of the left triangular plate is connected to the left side of the rear lower triangular plate. The front side of the right triangular plate is connected to the front upper triangular plate. The right side is connected, the rear side of the right triangle is connected to the right side of the rear upper triangle, the lower side of the front upper triangle is connected to the upper side of the front lower triangle, and the lower side of the rear upper triangle is connected to the lower side of the rear lower triangle. The upper sides of the left triangle, right triangle, front upper triangle, and front lower triangle are located on the same horizontal plane and form a rectangular opening. A rectangular discharge port is opened on the upper left side of the feeding pipe of the screw feeder. The lower vertex of the left triangle, the lower fixed point of the right triangle, the lower side of the front lower triangle, and the lower side of the rear lower triangle are all connected to the outer side of the rectangular discharge port of the feeding pipe of the screw feeder.

[0012] The angle between the upper front triangle and the lower front triangle is an obtuse angle, and the obtuse angle is located outside the storage bin. The upper rear triangle is symmetrically arranged with the upper front triangle, and the lower rear triangle is symmetrically arranged with the lower front triangle.

[0013] The left triangle is perpendicular to the center line of the screw conveyor, and the angle between the right triangle and the vertical plane is smaller than the angle between the left triangle and the vertical plane.

[0014] The width of the rectangular discharge port is equal to the inner diameter of the feed pipe of the screw conveyor, and the length of the rectangular discharge port is at least twice the inner diameter of the feed pipe.

[0015] The lower vertex of the left triangle and the lower fixed point of the right triangle are both arc-shaped groove structures that connect with the outer circle of the feeding pipe of the screw feeder.

[0016] By adopting the above technical solution, compared with the prior art, this utility model has the following beneficial effects:

[0017] 1) The discharge port at the bottom of the storage silo is changed from the existing square shape to a rectangular discharge port. The length of the rectangular discharge port is increased along the axis of the screw feeder, to three to four times the diameter of the screw shaft, to improve the feeding efficiency.

[0018] 2) The left triangular plate on the left side wall and the right triangular plate on the right side wall of the storage bin are still flat, but their shape and setting angle have changed (the surface area is reduced and the angle is increased). Because the rectangular discharge port is lengthened along the axial direction of the screw feeder, the angle between the left and right triangular plates and the vertical plane is closer to 90°, and the plane area is reduced, which greatly reduces the resistance of the left and right triangular plates to the powder.

[0019] 3) The front and rear side walls of the storage silo are changed from the existing flat surfaces to convex folded surfaces protruding into the silo. That is, the front side wall becomes a front upper triangular plate and a front lower triangular plate with an obtuse angle, and the rear side wall becomes a rear upper triangular plate and a rear lower triangular plate with an obtuse angle. Due to the change in shape and angle of the front and rear side walls of the storage silo, the flowability of the powder changes at the fold lines (the line connecting the lower side of the front upper triangular plate and the upper side of the front lower triangular plate, and the line connecting the lower side of the rear upper triangular plate and the lower side of the rear lower triangular plate). The plane above the fold line reduces the resistance of the powder, and the powder material is effectively guided and controlled in the silo. It also has the effect of dispersing the powder pressure, preventing the powder in the silo from being unable to flow smoothly from the bottom of the silo due to arching. This ensures the stability and uniformity of the screw conveyor's feeding.

[0020] 4) The upper and lower drawer-type filter components are inserted into the square tube between the air outlet at the top of the cover and the dehumidification pipe. The upper and lower drawer-type filter components are used interchangeably, with one in use and one on standby. The rectangular frame of the drawer-type filter component is equipped with a corrugated filter plate. The bottom and front and back sides of the corrugated filter plate have ventilation holes, but no ventilation holes are opened at the top. In this way, the filtration area is greatly increased and the number of ventilation holes is increased without changing the horizontal plane size, which greatly extends the service life of the filter component. Every so often, when the air permeability of the corrugated filter plate in the lower drawer-type filter assembly becomes poor, without stopping the machine, simply pull out the drawer of the lower drawer-type filter assembly by holding the handle. At this point, the upper drawer-type filter assembly will begin filtering. Remove the corrugated filter plate from the lower drawer-type filter assembly and replace it with a new one. Then, push the lower drawer-type filter assembly back into the square tube for continued use. After replacing the lower drawer-type filter assembly more than three times, the air permeability of the upper drawer-type filter assembly will also become poor. Again, pull out the upper drawer-type filter assembly and replace the corrugated filter plate. At this point, the lower drawer-type filter assembly will begin filtering. This ensures continuous production.

[0021] 5) The corrugated filter plate can be placed on the three support strips and removed by hand. Then, the new corrugated filter plate can be placed on the three support strips inside the rectangular frame. The whole replacement process takes no more than 1 minute and is convenient and quick.

[0022] 6) The corrugated filter plate does not have vents at the top to prevent the accumulation of difficult-to-clean agglomerates on the underside from clogging the vents. After replacing the corrugated filter plate, soak it in water for about twenty minutes, then rinse off the adhering yam powder with clean water. Cleaning is convenient. To prevent condensation from forming on the newly replaced corrugated filter plate after it is inserted into the square tube due to low temperature, it is generally preheated by placing the new corrugated filter plate above the heating chamber of the extruder before replacement.

[0023] 7) The front panel of the rectangular frame has a larger area than the rectangular opening on the front side of the square tube, and a sealing strip is installed to fit the front side of the square tube. This can seal the rectangular opening and improve the negative pressure dehumidification effect.

[0024] In summary, this utility model effectively solves the problem of poorly flowing powders (such as yam powder) easily bridging and clogging in the silo, which cannot ensure feeding and conveying efficiency. It has the advantages of smooth feeding, strong stability of conveying powder materials, stable feeding volume, uniform feeding, and no power consumption. The dehumidification pipeline adopts upper and lower drawer-type filter components arranged at intervals, which facilitates the replacement of corrugated filter plates with adhesive particles without stopping the machine during replacement, ensuring production efficiency, while ensuring dehumidification effect and food puffing quality.

The front side of the rectangular frame 6 is provided with a handle 8. The rear, left and right sides of the inner wall of the rectangular frame 6 are provided with support strips 9. The upper side of the three support strips 9 is lower than the upper side of the lower rectangular frame 6. The rectangular frame 6 is provided with a wave filter plate 10 placed on the three support strips 9.

[0037] The vertical cross section of the corrugated filter plate 10 is wavy in the left-right direction. Several air vents 11 are provided on the corrugated filter plate 10, and the air vents 11 are located in the lower middle part of the corrugated filter plate 10.

[0038] The front panel of the rectangular frame 6 has a larger area than the rectangular opening, and the rear side of the front panel of the rectangular frame 6 is provided with a sealing strip 12 that fits and contacts the front side of the square tube 2.

[0039] The powder material feeding device 13 includes a support frame 17, on which a storage bin 18 and a screw feeder 19 are mounted. The screw feeder 19 is inclined with the left side lower than the right side. A diagonal brace 20 is provided between the bottom right side of the support frame 17 and the right side of the screw feeder 19. The storage bin 18 includes a left triangular plate 21, a right triangular plate 22, a front upper triangular plate 23, a front lower triangular plate 24, a rear upper triangular plate 25, and a rear lower triangular plate 26. The left triangular plate 21 is inclined with the left side higher than the right side, and the right triangular plate 22 is inclined with the left side lower than the right side. The front side of the left triangular plate 21 is connected to the left side of the front lower triangular plate 24, and the rear side of the left triangular plate 21 is connected to the left side of the rear lower triangular plate 26. The front side of the right triangular plate 22 is connected to the front upper triangular plate 25. The right side of the upper triangular plate 23 is connected, the rear side of the right triangular plate 22 is connected to the right side of the rear upper triangular plate 25, the lower side of the front upper triangular plate 23 is connected to the upper side of the front lower triangular plate 24, and the lower side of the rear upper triangular plate 25 is connected to the lower side of the rear lower triangular plate 26. The upper sides of the left triangular plate 21, right triangular plate 22, front upper triangular plate 23, and front lower triangular plate 24 are located on the same horizontal plane and form a rectangular opening. A rectangular discharge port 27 is opened on the upper left side of the feeding pipe of the screw feeder 19. The lower vertex of the left triangular plate 21, the lower fixed point of the right triangular plate 22, the lower side of the front lower triangular plate 24, and the lower side of the rear lower triangular plate 26 are all connected to the outer side of the rectangular discharge port 27 of the feeding pipe of the screw feeder 19.

[0040] The included angle between the front upper triangular plate 23 and the front lower triangular plate 24 is an obtuse angle, and the obtuse angle is located outside the storage bin 18. The rear upper triangular plate 25 is symmetrically arranged with the front upper triangular plate 23, and the rear lower triangular plate 26 is symmetrically arranged with the front lower triangular plate 24.

[0041] The left triangle 21 is perpendicular to the center line of the screw feeder 19, and the angle between the right triangle 22 and the vertical plane is smaller than the angle between the left triangle 21 and the vertical plane.

[0042] The width of the rectangular discharge port 27 is equal to the inner diameter of the feed pipe of the screw feeder 19, and the length of the rectangular discharge port 27 is at least twice the inner diameter of the feed pipe.

[0043] The lower vertex of the left triangle 21 and the lower fixed point of the right triangle 22 are both arc groove structures 28 that connect with the outer circle of the feeding pipe of the screw feeder 19.

[0044] The working principle and beneficial effects of this utility model are as follows:

[0045] 1) The discharge port at the bottom of the storage bin 18 is changed from the existing square shape to a rectangular discharge port 27. The length of the rectangular discharge port 27 is extended along the axis of the screw feeder 19 to three to four times the diameter of the screw shaft, thereby improving the feeding efficiency.

[0046] 2) The left triangular plate 21 on the left side wall and the right triangular plate 22 on the right side wall of the storage bin 18 are still flat, but their shape and setting angle have changed (the surface area is reduced and the angle is increased). Because the rectangular discharge port 27 is lengthened along the axial direction of the screw feeder 19, the angle between the left triangular plate 21 and the right triangular plate 22 and the vertical plane is closer to 90°, and the plane area is reduced, which greatly reduces the resistance of the left triangular plate 21 and the right triangular plate 22 to the powder.

[0047] 3) The front and rear side walls of the storage bin 18 are changed from the existing flat surfaces to convex folded surfaces protruding into the bin. That is, the front side wall becomes a front upper triangular plate 23 and a front lower triangular plate 24 with an obtuse angle, and the rear side wall becomes a rear upper triangular plate 25 and a rear lower triangular plate 26 with an obtuse angle. Due to the change in shape and angle of the front and rear side walls of the storage bin 18, the flowability of the powder changes at the fold line (the line connecting the lower side of the front upper triangular plate 23 and the upper side of the front lower triangular plate 24, and the line connecting the lower side of the rear upper triangular plate 25 and the lower side of the rear lower triangular plate 26). The plane above the fold line reduces the resistance of the powder, and the powder material is effectively guided and controlled in the bin. It also has the effect of dispersing the powder pressure, preventing the powder in the bin from being unable to flow smoothly from the bottom of the bin due to arching. This ensures the feeding stability and uniformity of the screw conveyor 19.

[0048] 4) The upper drawer-type filter assembly 4 and the lower drawer-type filter assembly 5 are inserted into the square tube 2 between the air outlet at the top of the cover 1 and the dehumidification pipe 3. The upper drawer-type filter assembly 4 and the lower drawer-type filter assembly 5 are used interchangeably, with one in use and one on standby. A corrugated filter plate 10 is set in the rectangular frame 6 of the drawer-type filter assembly. The bottom and front and rear sides of the corrugated filter plate 10 have ventilation holes 11, but no ventilation holes 11 are opened at the top. In this way, the filtration area is greatly increased and the number of ventilation holes 11 is increased without changing the horizontal plane size, which greatly extends the service life of the filter assembly. Every so often, when the air permeability of the corrugated filter plate 10 of the lower drawer-type filter assembly 5 becomes poor, without stopping the machine, simply pull out the drawer of the lower drawer-type filter assembly 5 by holding handle 8. At this time, the upper drawer-type filter assembly 4 will begin its filtering function. Remove the corrugated filter plate 10 of the lower drawer-type filter assembly 5 and replace it with a new one. Then, push the lower drawer-type filter assembly 5 back into the square tube 2 for continued use. After the lower drawer-type filter assembly 5 has been replaced more than three times, the air permeability of the upper drawer-type filter assembly 4 will also become poor. Then, pull out the upper drawer-type filter assembly 4 again and replace the corrugated filter plate 10. At this time, the lower drawer-type filter assembly 5 will begin its filtering function. This ensures continuous production.

[0049] 5) The wave filter plate 10 can be placed on the three support plates 9 and removed by hand. Then, the new wave filter plate 10 is placed on the three support plates 9 inside the rectangular frame 6. The whole replacement process takes no more than 1 minute and is convenient and quick.

[0050] 6) The top of the corrugated filter plate 10 does not have vent holes 11 to prevent the vent holes 11 from being easily blocked by agglomerates that are difficult to clean and adhere to the bottom. The corrugated filter plate 10 can be soaked in water for about 20 minutes and then rinsed with clean water to remove the yam powder adhering to it. It is easy to clean. In order to prevent condensation from occurring when the newly replaced corrugated filter plate 10 is inserted into the square tube 2 due to the low temperature, the new corrugated filter plate 10 is generally placed above the heating chamber of the extruder 14 for preheating before replacement.

[0051] 7) The front panel of the rectangular frame 6 has a larger area than the rectangular opening on the front side of the square tube, and a sealing strip 12 is installed to fit against the front side of the square tube 2. This can seal the rectangular opening and improve the negative pressure dehumidification effect.

[0052] The extruder 14, screw feeder 19, and other auxiliary facilities in this utility model are all existing equipment, so their specific structures will not be described in detail.

[0053] The above embodiments illustrate the basic principles and features of this utility model. However, the above descriptions are merely preferred embodiments and are not limited to these embodiments. Those skilled in the art, inspired by this patent, can make many modifications and improvements without departing from the spirit and scope of the claims, all of which fall within the protection scope of this utility model. Therefore, the patent and its scope of protection should be determined by the appended claims.
