Anti-clogging screw conveyor

Abstract

This utility model relates to the field of screw conveyor technology, and more particularly to an anti-clogging screw conveyor. It includes a screw conveyor with a primary feed inlet inserted through its outer surface. An anti-clogging connecting cylinder is installed at the upper end of the primary feed inlet. Inside the anti-clogging connecting cylinder are a buffer plate, a guide plate, and a dispersing plate. The upper surface of the buffer plate has a buffer arc-shaped protrusion, the upper surface of the guide plate has a guide groove, and the upper surface of the dispersing plate has dispersing columns. Through the cooperation of the buffer plate, guide plate, dispersing plate, and flow regulating plate, this utility model firstly buffers and disperses the speed and state of materials entering the anti-clogging connecting cylinder in a pile, ensuring that the material ultimately enters the screw conveyor evenly. This prevents piles of material from falling too quickly into the initial end of the screw conveyor, forming accumulations and agglomerations, which could lead to blockages during the screw conveyor's operation, thus ensuring the stability of the screw conveyor's operation.

Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, and in particular to an anti-clogging screw conveyor. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can carry out horizontal, inclined or vertical conveying. It has the advantages of simple structure, convenient operation and convenient closed transport, and is widely used in various industries.

[0003] Traditional screw conveyors often have a fixed feed inlet. In order to increase speed, workers may pile up the material and place it inside the feed inlet.

[0004] Material piled up inside the feed inlet will rapidly accumulate at the initial end of the screw conveyor due to excessive feed volume and speed. This accumulation can cause agglomeration, leading to blockages during material transport. Furthermore, the fixed feed inlet size cannot be adjusted to accommodate materials with different characteristics. If easily agglomerated materials enter the screw conveyor with the same feed volume, agglomeration can easily occur at the initial end of the screw conveyor, further exacerbating the blockage problem.

[0005] Therefore, we provide a clog-resistant screw conveyor. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing an anti-clogging screw conveyor, thereby preventing clogging during the use of the screw conveyor.

[0007] In view of this, the present invention provides an anti-clogging screw conveyor, including a screw conveyor with an original feed inlet inserted through its outer surface. An anti-clogging connecting cylinder is installed at the upper end of the original feed inlet. The anti-clogging connecting cylinder is equipped with a buffer plate, a guide plate, and a dispersing plate. A buffer arc-shaped protrusion is installed on the upper surface of the buffer plate, a guide groove is opened on the upper surface of the guide plate, and a dispersing column is installed on the upper surface of the dispersing plate. A flow regulating plate is provided outside the dispersing plate. A screw is movably connected to one end of the flow regulating plate, and a screw cylinder is inserted into one end of the screw. A limit feed cylinder is inserted into the upper end of the anti-clogging connecting cylinder.

[0008] Preferably, the upper end of the original feed inlet is inserted through into the anti-clogging connecting cylinder. The size and specifications of the buffer plate, guide plate and dispersing plate are the same. The buffer plate, guide plate and dispersing plate are all inclined downward. The buffer plate and dispersing plate are located on the same vertical plane. The guide plate is located between the buffer plate and the dispersing plate. The guide plate and the buffer plate are symmetrically staggered. There are gaps between the upper end of the original feed inlet and the bottom end of the dispersing plate and the flow regulating plate.

[0009] Preferably, there are several buffer arc-shaped protrusions, and these several buffer arc-shaped protrusions are linearly and equidistantly distributed on the inclined surface of the buffer plate.

[0010] Preferably, there are several guide channels, which are linearly and equidistantly distributed at the inclined surface of the guide plate. The guide channels extend from the high end to the low end of the inclined surface of the guide plate, and the diameter of the guide channels gradually decreases from high to low.

[0011] Preferably, there are several dispersion columns, and the dispersion columns in adjacent rows are staggered.

[0012] Preferably, the upper end of the flow regulating plate is rotatably connected to the inner end surface of the guide plate, the screw barrel is inserted into the inner wall of the anti-clogging connecting cylinder, and the screw and the screw barrel are connected by a threaded engagement.

[0013] Preferably, the upper end of the anti-clogging connecting cylinder is provided with a feeding groove, the feeding groove and the buffer plate are located on the same vertical plane, and the lower end of the limiting feeding cylinder is inserted into the feeding groove.

[0014] Compared with the prior art, this utility model provides an anti-clogging screw conveyor with the following advantages:

[0015] 1. With the cooperation of the buffer plate, guide plate, dispersion plate and flow regulating plate, this utility model can first buffer and disperse the speed and state of the material entering the anti-clogging connecting cylinder in a pile, so that the material eventually enters the screw conveyor evenly, avoiding the pile of material falling too quickly into the initial end of the screw conveyor, forming accumulation and agglomeration, which would cause blockage during the screw conveyor conveying process, and ensuring the stability of the screw conveyor operation.

[0016] 2. This utility model, under the action of the flow regulating plate, screw and screw barrel, can control the size of the feed inlet according to the characteristics of the material, avoid the problem of material clumping at the initial end of the screw conveyor due to excessive quantity, further reduce the blockage problem of the screw conveyor, and ensure the stability of the screw conveyor during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: An anti-clogging screw conveyor, such as Figures 1-4 As shown, the device includes a screw conveyor 1, with a feed inlet 2 inserted through its outer surface. An anti-clogging connecting cylinder 3 is installed at the upper end of the feed inlet 2. Inside the anti-clogging connecting cylinder 3, there are a buffer plate 4, a guide plate 5, and a dispersing plate 6. A buffer arc-shaped protrusion 401 is installed on the upper surface of the buffer plate 4. A guide groove 501 is opened on the upper surface of the guide plate 5. A dispersing column 601 is installed on the upper surface of the dispersing plate 6. A flow regulating plate 7 is installed outside the dispersing plate 6. A screw 9 is movably connected to one end of the flow regulating plate 7. A screw cylinder 10 is inserted into one end of the screw 9. A limit feed cylinder 8 is inserted into the upper end of the anti-clogging connecting cylinder 3.

[0026] The upper end of the original feed inlet 2 is inserted into the anti-clogging connecting cylinder 3. The buffer plate 4, the guide plate 5, and the dispersing plate 6 are of the same size and specifications. The buffer plate 4, the guide plate 5, and the dispersing plate 6 are all inclined downwards. The buffer plate 4 and the dispersing plate 6 are located on the same vertical plane. The guide plate 5 is located between the buffer plate 4 and the dispersing plate 6. The guide plate 5 and the buffer plate 4 are symmetrically staggered. There are gaps between the upper end of the original feed inlet 2 and the dispersing plate 6 and the bottom end of the flow regulating plate 7.

[0027] There are several buffer arc-shaped protrusions 401, and these buffer arc-shaped protrusions 401 are linearly and equidistantly distributed on the inclined surface of the buffer plate 4.

[0028] There are several guide channels 501, which are linearly and equidistantly distributed at the inclined end of the guide plate 5. The guide channels 501 extend from the high end to the low end of the inclined surface of the guide plate 5, and the channel diameter of the guide channels 501 gradually shrinks from high to low.

[0029] There are several dispersed columns 601, and the dispersed columns 601 in adjacent rows are staggered.

[0030] The upper end of the flow regulating plate 7 is rotatably connected to the inner end surface of the guide plate 5, the screw barrel 10 is inserted into the inner wall of the anti-clogging connecting cylinder 3, and the screw 9 and the screw barrel 10 are threadedly engaged.

[0031] The screw conveyor 1 is suitable for horizontal operation. When conveying materials, the position of the flow regulating plate 7 is adjusted according to the characteristics of the materials. If conveying materials with good flowability, the feed opening between the flow regulating plate 7 and the dispersing plate 6 needs to be enlarged. Rotating the handle drives the screw 9 to rotate. Since the position of the screw barrel 10 is fixed, the screw 9 will move horizontally along the inside of the screw barrel 10. During the movement of the screw 9, the part connecting the screw 9 and the flow regulating plate 7 will rotate. Since the flow regulating plate 7 can only rotate in an arc, the screw 9 and the flow regulating plate 7 will rotate. Simultaneously, the connecting part of plate 7 slides upward, and screw 9 pushes the bottom end of flow regulating plate 7 to rotate away from the dispersing plate 6, increasing the input. When the material enters the anti-clogging connecting cylinder 3 through the limiting feed cylinder 8, the material will first fall onto the inclined surface of buffer plate 4. The material will not fall directly into the screw conveyor 1. At this time, the material will be further reduced in falling speed by the buffer arc protrusion 401 on buffer plate 4. When the material leaves the surface of buffer plate 4, it will fall onto the surface of guide plate 5. The material on the surface randomly enters the guide trough 501, dividing the pile of material into several portions for conveying. As the material conveyed by the guide trough 501 moves downward, it falls onto the surface of the dispersing plate 6. The dispersing columns 601 on the surface of the dispersing plate 6 further disperse and guide the material, so that the material finally enters the screw conveyor 1 in a uniformly dispersed state for conveying. With the cooperation of the buffer plate 4, guide plate 5, dispersing plate 6, and flow regulating plate 7, the speed and state of the material entering the anti-clogging connecting cylinder 3 in a pile can be buffered and dispersed. This ensures that the material enters the screw conveyor 1 evenly, preventing clumps of material from falling too quickly into the initial end of the screw conveyor 1, which could lead to blockages during the conveying process. This ensures the stability of the screw conveyor 1 during operation. Secondly, under the action of the flow regulating plate 7, screw 9, and screw barrel 10, the size of the feed inlet can be controlled according to the characteristics of the material, preventing the material from clumping at the initial end of the screw conveyor 1 due to excessive quantity. This further reduces the blockage problem of the screw conveyor 1 and ensures the stability of the screw conveyor 1 during operation.

[0032] like Figures 1-4 As shown, the upper end of the anti-clogging connecting cylinder 3 is provided with a feeding groove, the feeding groove and the buffer plate 4 are located on the same vertical plane, and the lower end of the limiting feeding cylinder 8 is inserted into the feeding groove.

[0033] When conveying materials, the materials are placed inside the limiting feed cylinder 8. The materials fall into the buffer plate 4 through the feed chute on the anti-clogging connecting cylinder 3. Under the action of the limiting feed cylinder 8 and the feed chute, the falling position of the materials can be accurately positioned to ensure that the materials can fall accurately into the buffer plate 4, thereby ensuring the perfect operation of subsequent work and further ensuring the anti-clogging effect of the screw conveyor 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
