Description

Technical Field

[0002] The plate centrifuge is a commonly used centrifugal separation equipment. Its working principle is to use the centrifugal force of high-speed rotation to separate materials into different components. Different types of separation can be achieved by using different centrifuge tubes or rotors. The plate centrifuge needs to be fed with materials through a feeder.

[0003] The cost of configuring a material distributor for the existing flat plate centrifuge is relatively high. However, the centrifuge without a material distributor has different material properties and fluidity, especially for materials with poor fluidity. The incoming material is sometimes fast, sometimes slow, sometimes more, sometimes less, causing the centrifuge drum to distribute the material unevenly, causing abnormal vibrations during the distribution, drying, and unloading process. This not only shortens the equipment maintenance cycle, consumes a lot of manpower and spare parts, and increases production and operation costs, but also causes severe vibrations to the equipment foundation and the personal safety of operators, and the equipment cannot operate stably for a long period of time, and cannot ensure continuous and stable production of the enterprise, thus causing greater economic losses to the enterprise.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a material distribution device, including a direct pipe 1, one end of the direct pipe 1 is fixedly connected to a first rubber spring tube 2, and the other end is fixedly connected to a reducer 5, the reducer 5 is made of 316L, the outer wall of the direct pipe 1 is sleeved with a bend pipe 4, the end of the bend pipe 4 away from the direct pipe 1 is sleeved with a second rubber spring tube 3, the end of the reducer 5 away from the direct pipe 1 is fixedly connected to a reduced diameter straight pipe 6, and the inner wall of the reduced diameter straight pipe 6 away from the reducer 5 is fixedly connected to a material distribution device; when working, the material enters the direct pipe 1 through the first rubber spring tube 2, and enters the reducer 5 through the direct pipe 1. The diameter inside the tube 5 gradually decreases, so the flow rate of the material entering the reducer 5 increases with the change of the tube diameter. Even if the material is uneven, the material will fill the entire reducer 5 after the diameter change of the reducer 5, solving the problem of uneven distribution of the centrifuge drum caused by the material being more or less at times. The material flowing out of the reducer 5 enters the shrinking straight tube 6. When passing through the material dividing device, the material is evenly distributed and flows out because of the separation of the material dividing device, making the centrifuge drum distribution very uniform, avoiding the violent vibration caused by uneven distribution, ensuring the long-term stable operation of key equipment and the continuous production, and eliminating the safety hazards caused by vibration to the equipment foundation and operators.

[0036] like Figure 1 and Figure 2As shown, the material dividing device includes four material dividing blades 8 fixed to the inner surface wall of the shrink straight tube 6 and distributed at 90 degrees to each other. The material dividing blades are in the shape of a right-angled trapezoid, with dimensions of 50mm in height, 22mm in upper width, 17mm in lower width and 5mm in thickness. The material is 316L. One end of the four material dividing blades 8 away from the inner surface wall of the shrink straight tube 6 is fixedly connected with a diverter shaft 7. The material of the diverter shaft 7 is 316L, the top is processed into a spherical shape, and the surface is smooth to reduce the resistance of the material passing through. A second blade mounting groove 61 is provided at the connection position between the inner surface wall of the shrink straight tube 6 and the material dividing blade 8, and a first blade mounting groove 71 is provided at the outer surface wall of the diverter shaft 7 and the corresponding connection position of the material dividing blade 8. It is a conical structure with a hollow interior and a smooth top. The hollow interior can effectively reduce production costs. The inner surface wall of the diverter shaft 7 is fixedly connected with reinforcing ribs 72 in sequence along the vertical direction. The reinforcing ribs 72 can effectively increase the strength of the diverter shaft 7; the two ends of the dividing blade 8 are respectively nested in the first blade mounting groove 71 and the second blade mounting groove 61. The diverter shaft 7 is a conical structure with a small top and a large bottom. When the material passes through the shrinking straight pipe 6 and enters the dividing device, the material will be diverted by the top of the diverter shaft 7, so that the material diverges to the periphery. At the same time, the dividing blade 8 divides the interior of the shrinking straight pipe 6 into four separation areas of the same size, and the material will form a circumferentially uniform distribution state in the separation area.

[0037] like Figures 4 to 8As shown, the dividing blade 8 is mainly composed of a first blade 81 and a second blade 82. A plug plate 811 is fixedly connected to the surface of one side of the first blade 81 close to the second blade 82. A slot 821 corresponding to the shape of the plug plate 811 is provided on the side of the second blade 82 close to the first blade 81. The first blade 81 and the second blade 82 are connected through the plug plate 811 and the slot 821. A first notch is provided on both sides of the top of the plug plate 811, and a second notch is provided on the inner wall of the slot 821 at a position corresponding to the first notch. The first notch and the second notch are fitted together to form a rectangular groove, and a limiting rod 83 is nested inside the rectangular groove. When installing the dividing blade 88, the four first blades 81 are correspondingly inserted into the first blade mounting groove 71 on the diverter shaft 7, and the four second blades 82 are inserted into the second blade mounting groove 61. The diverter shaft 7 with the installed first blade 81 is slidably connected to the slot 821 on the second blade 82 until the four plug plates 811 are correspondingly inserted into the slot 821, so that the plug plate 811 on the first blade 81 is tightly fitted with the slot 821 on the second blade 82, and then the limit rod 83 is inserted into the rectangular groove to fix the first blade 81 and the second blade 82. Since the four dividing blades 8 are distributed at 90°, after the dividing blades 8 are installed, the corresponding two dividing blades 8 are pressed against each other to fix the diverter shaft 7. The first blade 81 is connected to the second blade 82 through cooperation. During the entire installation process, the dividing blade 8 ensures the fixing strength without the need for fixing by welding, bolts, bonding, etc. At the same time, the dividing blade 8 is easy to disassemble for cleaning and maintenance.

[0038] like Figure 8 As shown, the surfaces of both sides of the first blade 81 and the second blade 82 are provided with corresponding mounting grooves 84, and the two ends of the dividing head 9 are fixedly connected with clamping blocks 91. The dividing blade 8 and the dividing head 9 are fixedly connected through the mounting grooves 84 and the clamping blocks 91. The dividing head 9 is a semicircular arc structure and is detachable. The semicircular arc dividing head 9 can reduce the impact force of the dividing device when diverting the material.

[0039] like Figure 7 and Figure 8 As shown, the first blade 81 and the plug plate 811 are an integrally formed structure, and the second blade 82 and the slot 821 are an integrally formed structure. The first blade 81 and the second blade 82 can be formed in one step by die casting during the manufacturing process, and the manufacturing process is simple.

[0040] The technical solution provided by the utility model is that the diameter of the inside of the reducer is gradually reduced by arranging a reducer and a material distribution device, and the flow rate of the material entering the reducer increases with the change of the pipe diameter. Even if the material is uneven, the material will fill the entire reducer after the diameter of the reducer is changed, thereby solving the problem of uneven distribution of the centrifuge drum caused by the amount of material varying from time to time. The material flowing out of the reducer enters the shrinking straight pipe, and when passing through the material distribution device, the material is evenly distributed and flows out because of the separation of the flow distribution shaft and the material distribution blades, so that the distribution of the centrifuge drum is very uniform, avoiding the violent vibration caused by uneven distribution, ensuring the long-term stable operation of key equipment and the continuous production, and eliminating the safety hazards caused by vibration to the equipment foundation and operators.

[0041] By setting the first blade and the second blade and connecting them through the cooperation, the dividing blade ensures the fixing strength during the whole installation process, and there is no need to fix it by welding, bolts and bonding. At the same time, the dividing blade is easy to disassemble for cleaning and maintenance. The first blade and the second blade can be formed by die casting at one time during the manufacturing process, and the manufacturing process is simple.

[0042] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
