Description

Technical Field

[0001] This utility model belongs to the technical field of material screening, and in particular relates to a uniform material distribution device for a square oscillating screen. Background Technology

[0002] The square gyratory screen is a high-efficiency screening device designed to simulate the principle of manual screening. It is named for its square shape and the three-dimensional composite motion of the material during screening, which resembles a gyratory motion. It is widely used in the grading of particulate materials in industries such as chemical, food, pharmaceutical, mining, and metallurgy. Its working principle is to use a motor to drive a vibrator to generate a complex motion that combines horizontal rotation, vertical vibration, and tilting oscillation, causing the material on the screen surface to be propelled forward in a spiral shape. At the same time, it uses screens with different aperture sizes to achieve precise stratification.

[0003] However, it still has the following drawbacks in actual use: most existing square gyratory screens do not have a material distribution device that can distribute materials evenly. This causes the materials to pile up in a relatively concentrated manner when placed, which affects the screening quality. At the same time, there are material distribution devices in related technical solutions, but these devices can only be adapted to square gyratory screens of a fixed model and size and do not have universality. Utility Model Content

[0004] The purpose of this invention is to provide a uniform material distribution device for a square gyratory screen. This invention solves the problem that most existing uniform material distribution devices have fixed models and cannot be adapted to different models and widths of square gyratory screens by setting up a material distribution component.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a square oscillating screen uniform material distribution device, including a material distribution component and a fixing component. The material distribution component includes a central shaft, and several connecting blocks are arranged on the outer periphery of the central shaft. A spring is fixed on the adjacent surface of each connecting block. The fabric assembly also includes a feeding hopper. The sidewalls of the feeding hopper are fixed with partition plates equal in number to the connecting blocks, and the spacing between the partition plates is equal. Each partition plate has a partition plate 1 hinged to its lower end. A partition plate 2 is inserted into the inner cavity of partition plate 1. The end of partition plate 2 protruding from partition plate 1 is hinged to the corresponding connecting block. The side wall of the feed hopper is also fixed with a side plate, and a movable plate is inserted into the inner cavity of the side plate. A connecting block located at the end of the central shaft is fixed with a connecting piece, and the end of the connecting piece away from the corresponding connecting block is fixedly connected to the movable plate.

[0006] Furthermore, the central shaft includes a shaft body one and a shaft body two that are inserted into each other, with the opposite ends of shaft body one and shaft body two respectively fixedly connected to their corresponding connecting blocks.

[0007] Furthermore, a side plate is provided on both sides of the feed hopper, and two movable plates are provided in the same side plate. Two connecting blocks located at both ends of the central shaft are fixed with a connecting piece, and two movable plates located on the same side of the device are fixed to the corresponding connecting piece.

[0008] Furthermore, a bellows is provided on the outer periphery of each spring, and both ends of each bellows are fixed to the opposite surfaces of two corresponding connecting blocks.

[0009] Furthermore, the fixing component includes a U-shaped clamp fixed to the connector, with a threaded rod horizontally threaded to the side of the U-shaped clamp away from the connector, and a handle fixed to the end of the threaded rod away from the U-shaped clamp.

[0010] Furthermore, there are two fixing components, which are respectively located on opposite sides of the two connectors. Each fixing component is also provided with two threaded rods and a corresponding handle.

[0011] This utility model has the following beneficial effects: 1. This utility model, through the setting of the material feeding assembly, when in use, the device is stretched, the first shaft and the second shaft separate, driving the connecting blocks at both ends to move, while the remaining connecting blocks are all set on the outer periphery of the central shaft. Since the springs used in this device are all the same size, model and specifications, the size and spacing of each partition cavity are equal, which ultimately allows the device to adapt to square gyratory screens of different sizes and widths. This solves the problem in the existing solution that when using square gyratory screens, there is no material feeding device that can evenly distribute the material, which easily affects the final screening quality due to uneven material distribution.

[0012] 2. The present invention, through the provision of a fabric assembly, can be fixedly installed according to the above structure for square gyratory screens of different widths without affecting its normal and uniform fabric distribution. This solves the problem that most of the existing uniform fabric distribution devices are fixed in model and cannot be adapted to square gyratory screens of different widths.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-5 As shown, this utility model is a square gyratory screen uniform material distribution device, including a material distribution component 1 and a fixing component 2. The material distribution component 1 includes a central shaft 11, and several connecting blocks 12 are arranged on the outer periphery of the central shaft 11. A spring 13 is fixed on the adjacent surface of each connecting block 12. The material distribution component 1 is mainly used to uniformly distribute the material onto the square gyratory screen, while the fixing component 2 is mainly used to fix the device to the feed end of the square gyratory screen. The connecting blocks 12 of the device mainly cooperate with the partition plate 16 and partition plate 2161 mentioned below to make the material uniformly distributed. The springs 13 used in this device are all the same size and model, which makes the stretching length of each spring 13 the same when one end is stretched. This makes the spacing between each partition plate 16 and partition plate 2161 the same, and ultimately the device can uniformly distribute the material onto the square gyratory screen.

[0017] The fabric assembly 1 also includes a feeding hopper 15. The sidewalls of the feeding hopper 15 are fixed with partition plates 151 in number equal to the number of connecting blocks 12, and the spacing between the partition plates 151 is equal. Each partition plate 151 has a partition plate 16 hinged to its lower end. A partition plate 2 161 is inserted into the inner cavity of the partition plate 16. The end of the partition plate 2 161 protruding from the partition plate 16 is hinged to the corresponding connecting block 12. The feeding hopper 15 is mainly for facilitating the loading of materials. After the materials enter the feeding hopper 15, they will flow into the device under the action of the equally distributed partition plates 151, partition plate 16 and partition plate 2 161, and finally spread laterally and evenly to the entire square gyratory screen for screening.

[0018] A side plate 17 is also fixed to the side wall of the feed hopper 15. A movable plate 171 is inserted into the inner cavity of the side plate 17. A connecting block 12 located at the end of the central shaft 11 is fixed with a connecting piece 18. The end of the connecting piece 18 away from the corresponding connecting block 12 is fixedly connected to the movable plate 171. The side plate 17 is mainly used to block the material from flowing out from both sides of the device. The movable plate 171 is a movable side baffle. When the device extends itself to adapt to square gyratory screens of different widths, it moves accordingly, which also serves to prevent the material from flowing out from the side.

[0019] Furthermore, the central shaft 11 includes a first shaft 111 and a second shaft 112 that are interlocked. The ends of the first shaft 111 and the second shaft 112 that are separated from each other are fixedly connected to their corresponding connecting blocks 12. The first shaft 111 and the second shaft 112 need to be adjusted according to the different sizes and models of square gyratory screens that the device is adapted to. The first shaft 111 and the second shaft 112 are interlocked to form the central shaft 11, but only one end of the two is in contact with each other. The ends that are not in contact are the two ends of the central shaft 11. At the same time, the two ends of the central shaft 11 are fixedly connected to the two connecting blocks 12 at both ends of the connecting block 12 group. When the device is stretched and extended, the first shaft 111 and the second shaft 112 separate and drive the connecting blocks 12 at both ends to move. The remaining connecting blocks 12 are all located on the outer periphery of the central shaft 11 and will not have any impact.

[0020] Furthermore, a side plate 17 is provided on both sides of the feed hopper 15, and two movable plates 171 are provided in the same side plate 17. Two connecting blocks 12 located at both ends of the central shaft 11 are fixed with a connecting piece 18. Two movable plates 171 located on the same side of the device are fixed to the corresponding connecting piece 18. There are four movable plates 171. Each connecting piece 18 has two movable plates 171 located on different sides. This makes the movable plates 171 protrude with the device when it is stretched, preventing the material from flowing out from the side.

[0021] Furthermore, a bellows 14 is provided on the outer periphery of each spring 13. Both ends of each bellows 14 are fixed to the opposite surfaces of two corresponding connecting blocks 12. The bellows 14 are to prevent the material falling during the feeding process from hitting the spring 13 and the central shaft 11.

[0022] Furthermore, the fixing component 2 includes a U-shaped clamping member 21 fixed to the connecting member 18. The side of the U-shaped clamping member 21 away from the connecting member 18 is horizontally threaded with a threaded rod 22, and the end of the threaded rod 22 away from the U-shaped clamping member 21 is fixed with a handle 23. The fixing component 2 is mainly used to stably fix the entire device to the square gyratory screen. The U-shaped clamping member 21 is mainly used to clamp onto the side wall of the screen box at the feed end of the square gyratory screen, and then a certain force is applied to it through the threaded rod 22 to make it press against the screen, so that the device is stably fixed.

[0023] Furthermore, there are two fixing components 2, which are respectively located on opposite sides of the two connectors 18. Each fixing component 2 is also provided with two threaded rods 22 and corresponding handles 23. The two fixing components 2 are used to stably fix the device on the two side walls of the box at the feed end of the square gyratory screen. The two threaded rods 22 are provided to further improve the stability of its fixation.

[0024] The specific working principle of this utility model is as follows: When using this device, it is fixed to the feed end of the square gyratory screen by the fixing component 2, and then the material to be screened is placed into the feed hopper 15. The device is equipped with equally divided partition plates 151, partition plate one 16, and partition plate two 161. After the material enters the feed hopper 15, it will enter from the equidistant inlet end under the action of the evenly distributed partition plates 151, and then flow out from the equidistant outlet end, so that the material is evenly distributed laterally on the square gyratory screen for screening. This device can be installed and used according to different models and sizes of square gyratory screens and ensures uniform material distribution. When the device is stretched, the shaft one 111 and the shaft The two shafts 111 and 112 are separated. The two shafts 111 and 112 are interlocked to form a central shaft 11, but only one end of each shaft is in contact with the other end. The two ends of the shaft 11 are respectively the two ends of the central shaft 11. At the same time, the two ends of the central shaft 11 are fixedly connected to the two connecting blocks 12 at both ends of the connecting block 12 group. When the device is stretched, the two shafts 111 and 112 separate, which drives the connecting blocks 12 at both ends to move. The remaining connecting blocks 12 are all set on the outer periphery of the central shaft 11. Since the springs 13 used in the device are all the same size and model, the size and spacing of each partition cavity are equal. Ultimately, the device can adapt to square gyratory screens of different widths, which greatly improves its practicality.

[0025] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
