Description

Technical Field

[0001] The utility model relates to the technical field of a material return structure for a feed pelletizer, in particular to a material return structure for a feed pelletizer. Background Art

[0002] The pelletizer is a machine that continuously squeezes and shears a certain proportion of materials to form and gradually increase them into granular products. During the feed pelletizing process, the friction and extrusion between the pelletizing chamber mold and the pressing roller generate high temperatures, evaporating some water. This causes a lot of steam to come out of the pelletizer. Another reason is that the feeding auger feeds slowly, causing the material to be pressed in the pelletizing chamber for a longer time, which causes most of the water in the material to evaporate, resulting in excessive steam.

[0003] If the steam in the feed pelletizer is not extracted in time, the finished product will have poor molding degree, and some materials will adhere to the inner wall of the pelletizer, affecting the discharge. In order to ensure the molding effect of the pellets and the quality of the product, it is necessary to eliminate gas and moisture to improve the quality of the finished product. Usually, a fan is added to the feed pelletizer to extract the steam from the pelletizing chamber during the pelletizing process.

[0004] However, during the conventional steam extraction process, a large amount of powdered raw materials are brought out, resulting in a waste of raw materials and an increase in production costs. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the utility model proposes a return material structure for a feed pelletizer, including an air intake pipe connected to the pelletizer, the air intake pipe is connected to a buffer box at one end away from the pelletizer, the buffer box is also connected to an exhaust pipe, the exhaust pipe is connected to the air inlet of an air pump, the bottom end of the buffer box is connected to a discharge pipe, the end of the discharge pipe away from the buffer box is connected to the feed hopper of a bucket elevator, and a buffer component is provided in the buffer box, through which powder in the air is extracted and retained in the buffer box and enters the discharge pipe.

[0006] To achieve the above purpose, a vacuum pump is used to provide power to extract the gas in the granulator, and the gas enters the buffer box and the exhaust pipe in sequence along the flow direction through the air inlet pipe. Part of the powdered material enters the buffer box along with the gas, and the powdered material is retained in the buffer box through the buffer component and enters the feed hopper of the bucket elevator through the discharge pipe. The powdered material entering the bucket elevator from the feed hopper moves to the processing equipment along with the material in the bucket elevator, thereby realizing the recycling of materials, reducing raw material waste, and lowering production costs.

[0007] Furthermore, the buffer assembly includes a first ventilation plate and a first material baffle plate which are arranged in the buffer box and are integrated with the inner groove wall of the buffer box. A number of first ventilation holes are evenly opened on the first ventilation plate, the first material baffle plate covers the exhaust pipe, a square hole is opened on the first material baffle plate, and a ventilation material baffle net covering the square hole is fixed on the first material baffle plate.

[0008] Through the above technical solution, the air and dust materials in the granulator pass through the first ventilation plate through the first ventilation hole. The dust materials passing through the first ventilation plate are blocked by the ventilation blocking net and cannot enter the exhaust pipe through the first blocking plate, while the gas can enter the exhaust pipe normally through the ventilation blocking net.

[0009] Furthermore, a second ventilation plate and a second material baffle plate are fixed to the inner groove wall of the buffer box, and are located between the first ventilation plate and the first material baffle plate. Second ventilation holes are evenly arranged on the second ventilation plate and staggered with the first ventilation holes.

[0010] Through the above technical solution, through the cooperation of the second ventilation plate and the second material baffle plate, the possibility of the material being retained in the buffer box is further increased, and the possibility of the powdered material entering the exhaust pipe is reduced.

[0011] Furthermore, a groove is provided on the hopper, and a baffle for adjusting the size of the feed hopper entrance is slidably connected in the groove. The top of the baffle extends out of the groove, and the part of the baffle extending out of the groove is connected to the feed hopper through an adjusting component.

[0012] Through the above technical solution, the baffle is supported by the groove, the baffle and the groove are adapted to each other, and the height of the baffle extending out of the feed hopper is controlled by the adjustment component, thereby adjusting the size of the feed hopper entrance and reducing the possibility of material blockage in the feed hopper.

[0013] Furthermore, the adjustment assembly includes a clip fixed at the top position of the baffle, the clip has an L-shaped cross-section, an axial mounting plate is fixed to the outer wall of the bucket elevator, and a plurality of vertically evenly arranged support clips are fixed on the side of the mounting plate facing away from the bucket elevator. The gap size between each two adjacent support clips is adapted to the size of the clip, and the clip is inserted into the gap between the two support clips at the appropriate position and is connected to the support clips.

[0014] Through the above technical solution, two supporting pallets of appropriate height are selected as needed, and the staff inserts the card strip into the gap between the two adjacent supporting pallets. The card strip is supported by the supporting pallet located on the lower side of the card strip, and the possibility of the card strip falling out of the supporting pallet without external force is reduced by the supporting pallet located on the upper side of the card strip.

[0015] Furthermore, a rubber sealing ring is fixed to the inner wall of the groove to seal the gap between the groove and the baffle.

[0016] Through the above technical solution, a rubber sealing ring is provided to close the gap between the baffle and the groove, thereby reducing the possibility of material in the bucket elevator overflowing from the gap between the groove and the baffle.

[0017] In summary, the feed pelletizing machine's material return structure has the following beneficial effects:

[0018] (1) The feed pelletizer adopts a return material structure, which is powered by an air pump to extract the gas in the pelletizer. The gas enters the buffer box and the exhaust pipe in the direction of flow through the air inlet pipe. Part of the powdered material enters the buffer box along with the gas. The powdered material is retained in the buffer box through the buffer component and enters the hopper of the bucket elevator through the discharge pipe. The powdered material entering the bucket elevator from the hopper moves to the processing equipment along with the material in the bucket elevator, thereby realizing the recycling of materials, reducing the waste of raw materials, and reducing production costs.

[0019] (2) The feed pelletizing machine uses a material return structure, which further increases the possibility of material being retained in the buffer box through the cooperation of the second ventilation plate and the second material baffle plate, and reduces the possibility of powdered material entering the exhaust pipe.

[0020] (3) The feed pelletizer uses a return material structure, which supports the baffle through a groove. The baffle and the groove are adapted to each other. The height of the baffle extending out of the feed hopper is controlled by an adjustment component, thereby adjusting the size of the feed hopper entrance and reducing the possibility of material clogging in the feed hopper.

[0026] The technical solution of the present invention will be more clearly and completely explained below by describing the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0027] like Figure 1-3 As shown, a return material structure for a feed pelletizer in the preferred embodiment of the present invention includes an air intake pipe 1 connected to the pelletizer, the air intake pipe 1 is connected to a buffer box 2 at one end away from the pelletizer, the buffer box 2 is also connected to an exhaust pipe 3, the exhaust pipe 3 is connected to the air inlet of the vacuum pump, the bottom end of the buffer box 2 is connected to a discharge pipe 4, the end of the discharge pipe 4 away from the buffer box 2 is connected to the feed hopper 6 of the bucket elevator 5, the air intake pipe 1, the buffer box 2, the exhaust pipe 3, the discharge pipe 4 and the feed hopper 6 of the bucket elevator 5 are connected to each other, and a buffer component 7 is provided in the buffer box 2, in which powder extracted from the air is retained in the buffer box 2 and enters the discharge pipe 4.

[0028] like Figure 1 The power is provided by the vacuum pump to extract the gas in the granulator. The gas enters the buffer box 2 and the exhaust pipe 3 in sequence along the flow direction through the air inlet pipe 1. Part of the powdered material enters the buffer box 2 along with the gas. The powdered material is retained in the buffer box 2 through the buffer component 7 and enters the feed hopper 6 of the bucket elevator 5 through the discharge pipe 4. The powdered material entering the bucket elevator 5 from the feed hopper 6 is moved to the processing equipment along with the material in the bucket elevator 5, thereby realizing the recycling of materials, reducing the waste of raw materials, and reducing production costs.

[0029] like Figure 3 The buffer assembly 7 includes a first ventilation plate 701 and a first baffle plate 702 which are arranged in the buffer box 2 and are integrated with the inner groove wall of the buffer box 2. A number of first ventilation holes 703 are evenly opened on the first ventilation plate 701, and the first baffle plate 702 covers the exhaust pipe 3. A square hole 704 is opened on the first baffle plate 702, and a ventilation baffle net 705 covering the square hole 704 is fixed on the first baffle plate 702. The gas and powdered material entering the buffer box 2 must pass through the first ventilation plate 701, and the gas entering the exhaust pipe 3 must pass through the ventilation baffle net 705.

[0030] like Figure 3The air and dust materials in the granulator pass through the first ventilation plate 701 through the first ventilation hole 703. The dust materials passing through the first ventilation plate 701 are blocked by the ventilation blocking net 705 and cannot enter the exhaust pipe 3 through the first blocking plate 702, while the gas can enter the exhaust pipe 3 normally through the ventilation blocking net 705.

[0031] like Figure 3 The inner groove wall of the buffer box 2 is also fixed with a second ventilation plate 706 and a second baffle plate 707 located between the first ventilation plate 701 and the first baffle plate 702. The second ventilation plate 706 is evenly provided with second ventilation holes 708 that are staggered with the first ventilation holes 703. The top and bottom of the second ventilation plate 706 and the second baffle plate 707 are not in contact with the groove top and groove bottom of the buffer box 2. Through the cooperation of the second ventilation plate 706 and the second baffle plate 707, the possibility of material retention in the buffer box 2 is further increased, and the possibility of powdered material entering the exhaust pipe 3 is reduced.

[0032] like Figure 1 and Figure 2 In order to adjust the size of the feed hopper 6 entrance, a groove 8 is provided on the hopper. A baffle 9 for adjusting the size of the feed hopper 6 entrance is slidably connected in the groove 8. The top of the baffle 9 extends out of the groove 8. The part of the baffle 9 extending out of the groove 8 is connected to the feed hopper 6 through an adjusting component 10. The groove 8 is used to support the baffle 9. The baffle 9 and the groove 8 are adapted to each other. The height of the baffle 9 extending out of the feed hopper 6 is controlled by the adjusting component 10, thereby adjusting the size of the feed hopper 6 entrance and reducing the possibility of material blockage in the feed hopper 6.

[0033] like Figure 1 and Figure 2 The adjustment component 10 includes a clip 1101 fixed at the top position of the baffle 9. The cross-section of the clip 1101 is L-shaped. An axial mounting plate 1102 is fixed to the outer wall of the bucket elevator 5. A plurality of vertically evenly arranged support clips 1103 are fixed on the side of the mounting plate 1102 facing away from the bucket elevator 5. The gap size between each two adjacent support clips 1103 is adapted to the size of the clip 1101. The clip 1101 is inserted into the gap between the two support clips 1103 at the appropriate position and is connected to the support clip 1103 by snapping.

[0034] like Figure 1 and Figure 2 , select two supporting card plates 1103 of appropriate height as needed, and the staff inserts the card strip 1101 into the gap between the two adjacent supporting card plates 1103, and supports the card strip 1101 through the supporting card plate 1103 located on the lower side of the card strip 1101, and reduces the possibility of the card strip 1101 falling off the supporting card plate 1103 without external force through the supporting card plate 1103 located on the upper side of the card strip 1101.

[0035] like Figure 1 and Figure 2 A rubber sealing ring is fixed on the inner wall of the groove 8 to seal the gap between the groove 8 and the baffle 9. By setting the rubber sealing ring, the gap between the baffle 9 and the groove 8 is closed, reducing the possibility of material in the bucket elevator 5 overflowing from the gap between the groove 8 and the baffle 9.

[0036] When in use, the power is turned on and the switch is turned on. The staff selects two supporting cards 1103 at appropriate positions so that the card strip 1101 is inserted into the gap between the two supporting cards 1103. The position of the baffle 9 is positioned by the cooperation between the supporting cards 1103 and the card strip 1101 to control the size of the feeding port of the feed hopper 6.

[0037] Then turn on the vacuum pump, which provides power so that the gas in the granulator enters the buffer box 2 through the air inlet pipe 1. At the same time, part of the powdered material in the granulator enters the buffer box 2 together with the gas. The apertures of the first ventilation hole 703 and the second ventilation hole 708 are both larger than the apertures of the powdered material. The powdered material and air entering the buffer box 2 pass through the first ventilation hole 703 and the second ventilation hole 708 and pass through the first ventilation plate 701 and the second ventilation plate 706. The first ventilation hole 703 and the second ventilation hole 708 are arranged in an alternating manner. The powdered material passing through the first ventilation plate 701 will hit the knife of the second ventilation plate 706, and then enters the discharge pipe 4 through the gap between the second ventilation plate 706 and the bottom of the buffer box 2 under the action of gravity. The powdered material passing through the second ventilation plate 706 hits the second baffle plate 707 and falls into the discharge pipe 4 under the action of gravity. The material entering the gap between the first baffle plate 702 and the second baffle plate 707 hits the ventilation baffle net 705 and falls into the discharge pipe 4 through the gap between the first baffle plate 702, the second baffle plate 707 and the bottom of the buffer box 2, thereby reducing the possibility of powdered material entering the exhaust pipe 3. The powdered material enters the discharge pipe 4 and the gas enters the exhaust pipe 3.

[0038] The powdered material entering the discharge pipe 4 enters the feed hopper 6 of the bucket elevator 5. After the device has been working for a period of time, the staff grabs the card strip 1101 and manually pulls the card strip 1101 outward. The card strip 1101 is moved out from the gap between the two supporting card plates 1103. Then the card strip 1101 is inserted into the gap between the two appropriate supporting card plates 1103 to increase the feed port of the feed hopper 6. The powdered material in the feed hopper 6 passes through the baffle 9 and enters the bucket elevator 5. The bucket elevator 5 provides power, so that the powdered material in the feed hopper 6 enters the granulator along with the material in the bucket elevator 5, reducing waste.
