Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge technology, and in particular to a disc centrifuge with automatic feed flow control. Background Technology
[0002] Disc centrifuges are a type of vertical centrifuge that can quickly and continuously separate solids from liquids and liquids from liquids. The drum is mounted on the top of a vertical shaft and is driven by an electric motor to rotate at high speed through a transmission device. Inside the drum are a set of disc-shaped parts—discs—that are nested together with very small gaps between them. The suspension is added to the drum through a feed pipe located in the center of the drum. As the suspension flows through the gaps between the discs, the solid particles settle onto the discs under the action of the centrifuge, forming sediment. The sediment slides along the surface of the discs, detaches from the discs, and accumulates in the largest diameter part of the drum. The separated liquid is discharged from the drum through the outlet. In a disc centrifuge, the drum is the main working component, but the rotation of the drum requires an electric motor as a power source. The power of the electric motor is transmitted to the drum through the vertical shaft to drive its normal operation.
[0003] Existing technologies, such as patent CN210496839U, disclose a disc centrifuge. This patent uses an upper casing and a lower base. The upper casing is fixedly mounted on the lower base. The top of the upper casing has an inlet / outlet device, and inside it is a rotating device and a vertical shaft connecting the rotating device. The bottom of the vertical shaft is rotatably mounted on the lower base. A motor is located outside the lower base, and a horizontal shaft is rotatably mounted inside it. This invention solves the problem that in existing equipment, the working parts and the rotating drum device have a large starting mass, resulting in a large moment of inertia. Therefore, at the moment of startup, the motor experiences a very large resistance torque, which can easily cause motor overload and overheating.
[0004] In daily operation, during the use of the equipment, it is difficult to control the amount of material entering the equipment body. When the equipment body is centrifugally separated, the excessive amount of material inside makes it difficult for the equipment to separate quickly, resulting in a slow separation speed. When there is a lot of material, it is easy for the material to accumulate excessively inside the equipment body, causing the equipment to malfunction. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult to accurately control the flow rate of materials entering the equipment, resulting in the equipment being difficult to use normally. Therefore, this invention proposes a disc centrifuge with automatic feed flow control.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a disc centrifuge with automatic feed flow control, comprising a support, a main body, a body, a discharge pipe, and a first motor. The main body is fixedly connected to the upper end of the support, the body is fixedly connected to the upper end of the main body, the first motor is fixedly connected to the side of the main body, the discharge pipe is fixedly connected to the side of the body, a feeding device is fixedly connected to the upper end of the body, the feeding device includes a first connecting pipe and a second connecting pipe, the second connecting pipe is fixedly connected to the upper end of the body, the first connecting pipe is fixedly connected to the side of the second connecting pipe away from the body, an electronic control valve is fixedly connected to the surface of the first connecting pipe near the second connecting pipe, a pump body is fixedly connected to the surface of the first connecting pipe, and a second motor is fixedly connected to the upper end of the pump body.
[0007] Furthermore, a rotating block is fixedly connected to the output end of the second motor, and a rotating rod is fixedly connected to the lower end of the rotating block. By setting the rotating rod, the rotating block can be limited to rotate, reducing the possibility that the rotating block may vibrate inside the pump body during use, causing the rotating block to impact and damage the pump body.
[0008] Furthermore, a limiting block is rotatably connected to the surface of the rotating rod, and the limiting block is fixedly connected to the bottom of the pump body. The limiting block is provided to facilitate limiting the rotation of the rotating rod.
[0009] Furthermore, blades are fixedly connected to the surface of the rotating block, and the blades are rotatably connected inside the pump body.
[0010] Furthermore, an auxiliary component is fixedly connected to the upper end of the second connecting pipe. The auxiliary component includes a pressure-reducing chamber and a connecting column. The pressure-reducing chamber is fixedly connected to the upper end of the second connecting pipe, and the connecting column is fixedly connected to the upper end of the pressure-reducing chamber. A moving block is slidably connected inside the pressure-reducing chamber, and a rubber ring is fixedly connected to the surface of the moving block. A moving rod is fixedly connected to the upper end of the moving block and slidably connected inside the connecting column. A fixing block is fixedly connected to the upper end of the moving rod and slidably connected inside the connecting column. By setting the rubber ring, the gap between the moving block and the pressure-reducing chamber can be sealed, reducing the possibility of material overflowing from the gap between the moving block and the pressure-reducing chamber during equipment use.
[0011] Furthermore, a first spring is sleeved and connected to the surface of the movable rod.
[0012] Furthermore, one end of the first spring is fixedly connected to the surface of the moving block, and the end of the first spring away from the moving block is fixedly connected to the interior of the pressure relief chamber. The first spring is provided to facilitate the application of a reset force to the moving block for reset.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] In this invention, by setting up a feeding device, when feeding material into the main body, the electronic control valve and the second motor are activated. The second motor then drives the rotating block and the rotating rod to rotate inside the limit block. When the rotating block rotates, it drives the blades to rotate inside the pump body, allowing the material inside the first connecting pipe to enter the main body through the second connecting pipe for centrifugal separation. This feeding device, through the coordinated work of components such as the first connecting pipe, the second connecting pipe, the electronic control valve, the pump body, the second motor, the rotating block, the rotating rod, the limit block, and the blades, achieves precise automatic feeding flow control, improving the separation effect and production efficiency.
[0015] In this invention, by setting an auxiliary component, when the equipment feeds material into the main body, the material enters the main body through the second connecting pipe. Due to the excessive speed of the material entering, some material inside the second connecting pipe enters the pressure reducing chamber and moves the moving block upward. When the moving block moves, it drives the moving rod and the first spring to move. The first spring deforms and generates elastic force. This auxiliary component, through components such as the pressure reducing chamber, connecting column, moving block, rubber ring, moving rod, fixed block, and first spring, effectively reduces the pressure of the feed and protects the equipment, extends the service life of the equipment, and improves the stability and reliability of the equipment.

[0023] The specific setup and function of its feeding device 6 and auxiliary components 7 will be explained below.
[0024] In this embodiment: a feeding device 6 is fixedly connected to the upper end of the main body 3. The feeding device 6 includes a first connecting pipe 61 and a second connecting pipe 62. The second connecting pipe 62 is fixedly connected to the upper end of the main body 3. The first connecting pipe 61 is fixedly connected to the side of the second connecting pipe 62 away from the main body 3. An electronic control valve 64 is fixedly connected to the surface of the first connecting pipe 61 near the second connecting pipe 62. The electronic control valve 64 can accurately control the flow rate of material entering the second connecting pipe 62 according to the set parameters. A pump body 63 is fixedly connected to the surface of the first connecting pipe 61. A second motor 65 is fixedly connected to the upper end of the pump body 63. By adjusting the speed of the second motor 65, the conveying speed of the material can be flexibly controlled, thereby achieving precise adjustment of the feeding flow rate.
[0025] Specifically, a rotating block 66 is fixedly connected to the output end of the second motor 65, and a rotating rod 68 is fixedly connected to the lower end of the rotating block 66.
[0026] In this embodiment: by setting the rotating rod 68, the rotating block 66 can be limited to rotate, which reduces the possibility that the rotating block 66 may vibrate inside the pump body 63 during use, causing the rotating block 66 to impact and damage the pump body 63.
[0027] Specifically, a limit block 69 is rotatably connected to the surface of the rotating rod 68. The limit block 69 is fixedly connected to the bottom inside the pump body 63. The limit block 69 is provided to facilitate the limiting of the rotating rod 68.
[0028] Specifically, blades 67 are fixedly connected to the surface of the rotating block 66. The blades 67 are rotatably connected inside the pump body 63. The rotatable connection between the rotating rod 68 and the limiting block 69 enables the rotating rod 68 to remain stable during rotation, reducing the impact of shaking on the normal operation of the blades 67.
[0029] The second motor 65 drives the rotating block 66 and the rotating rod 68 to rotate, which in turn drives the blade 67 to rotate inside the pump body 63, conveying the material from the first connecting pipe 61 to the second connecting pipe 62 and into the main body 3.
[0030] In this embodiment: An auxiliary component 7 is fixedly connected to the upper end of the second connecting pipe 62. The auxiliary component 7 includes a pressure reducing chamber 71 and a connecting column 72. The pressure reducing chamber 71 is fixedly connected to the upper end of the second connecting pipe 62, and the connecting column 72 is fixedly connected to the upper end of the pressure reducing chamber 71. A moving block 73 is slidably connected inside the pressure reducing chamber 71. A rubber ring 74 is fixedly connected to the surface of the moving block 73. The rubber ring 74 is tightly fitted to the inner wall of the pressure reducing chamber 71 to prevent material leakage. A moving rod 75 is fixedly connected to the upper end of the moving block 73. The moving rod 75 is slidably connected inside the connecting column 72. A fixing block 76 is fixedly connected to the upper end of the moving rod 75. The fixing block 76 is slidably connected inside the connecting column 72.
[0031] In this embodiment, by setting a rubber ring 74, the gap between the moving block 73 and the pressure reducing chamber 71 can be sealed, reducing the possibility of material overflowing from the gap between the moving block 73 and the pressure reducing chamber 71 during use.
[0032] Specifically, a first spring 77 is sleeved and connected to the surface of the moving rod 75.
[0033] Specifically, one end of the first spring 77 is fixedly connected to the surface of the moving block 73, and the end of the first spring 77 away from the moving block 73 is fixedly connected to the interior of the pressure relief chamber 71. The first spring 77 is provided to facilitate the application of a reset force to the moving block 73 for reset.
[0034] Working principle: When feeding material into the body 3, the electronic control valve 64 and the second motor 65 are activated. The second motor 65 then drives the rotating block 66 to rotate the rotating rod 68 inside the limiting block 69. When the rotating block 66 rotates, it drives the blades 67 to rotate inside the pump body 63, allowing the material inside the first connecting pipe 61 to enter the body 3 through the second connecting pipe 62 for centrifugal separation. This feeding device 6 achieves precise automatic feeding flow control through the coordinated work of components such as the first connecting pipe 61, the second connecting pipe 62, the electronic control valve 64, the pump body 63, the second motor 65, the rotating block 66, the rotating rod 68, the limiting block 69, and the blades 67, thereby improving the separation effect and production efficiency.
[0035] When the equipment feeds material into the body 3, the material enters the body 3 through the second connecting pipe 62. Due to the excessive speed of the material entering, some material inside the second connecting pipe 62 enters the pressure reducing chamber 71 and moves the moving block 73 upward. When the moving block 73 moves, it drives the moving rod 75 and the first spring 77 to move. The first spring 77 moves and deforms to generate elastic force. This auxiliary component 7, through components such as the pressure reducing chamber 71, connecting column 72, moving block 73, rubber ring 74, moving rod 75, fixed block 76, and first spring 77, effectively reduces the pressure of the feed and protects the equipment, extends the service life of the equipment, and improves the stability and reliability of the equipment.
