Description

Technical Field

[0001] This utility model relates to the field of drum end cap forging technology, and in particular to a drum end cap forging for centrifuges. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions (e.g., separating cream from milk). They can also be used to remove liquid from wet solids, such as in a washing machine to spin-dry wet clothes. Special high-speed tubular centrifuges can also separate gas mixtures of different densities. Utilizing the different settling velocities of solid particles of different densities or sizes in liquids, some sedimentation centrifuges can also classify solid particles according to density or size. They are widely used in chemical, food, pharmaceutical, light industry, mineral processing, and wastewater treatment industries. The forged end cap of the centrifuge drum is an important component of the centrifuge. Installed on the centrifuge drum, it prevents the material to be separated or filtered from being thrown out of the centrifuge due to excessive centrifugal force during high-speed rotation. The term "forging" refers to a workpiece or blank obtained by forging and deforming a metal billet.

[0003] However, in actual use, the assembly holes of the centrifuge drum end cover forgings will wear out significantly after a long period of use, requiring the replacement of the entire drum end cover. This makes it difficult to reduce maintenance costs. In addition, the drum end cover will generate a lot of heat during high-speed rotation, which is not conducive to improving the stability of equipment operation. Utility Model Content

[0004] The purpose of this invention is to provide a forged drum end cap for centrifuge, which solves the problems mentioned in the background art of not being convenient for reducing maintenance costs and not being convenient for improving the stability of equipment operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge drum end cap forging, comprising a drum end cap forging body, an assembly hole being formed in the middle of one side of the drum end cap forging body, a replacement component being inserted into the assembly hole, and heat dissipation components being provided around one side surface of the drum end cap forging body.

[0006] The replacement component includes a connecting inner cylinder inserted into the assembly hole, one end of which is fixedly connected to an assembly seal, and a snap-fit ​​fastener is fixedly sleeved on the surface of the connecting inner cylinder.

[0007] The heat dissipation assembly includes thermally conductive silicone rubber sheets that are disposed around one side of the main body of the drum end cap forging, and heat dissipation fins are provided on one side of the thermally conductive silicone rubber sheets.

[0008] As a further embodiment of this utility model, an assembly is welded to the surface of one end of the main body of the drum end cover forging. The surface of the assembly has four threaded holes, and the internal threads of the threaded holes are connected to assembly bolts, which facilitate the fixing of the fastener.

[0009] As a further embodiment of this utility model, the surface of the snap-fit ​​fastener is provided with four connecting holes, which are adapted to the assembly bolts and facilitate connection with the assembly components.

[0010] As a further embodiment of this utility model, the surface of the heat dissipation fins is provided with four fixing holes, and a fixing post passes through the inside of the fixing holes. One end of the fixing post is threaded to one side of the main body of the drum end cover forging. The fixing post facilitates the replacement and maintenance of the heat dissipation fins.

[0011] As a further embodiment of this utility model, a slot is provided on the other side of the main body of the drum end cover forging. The slot is adapted to the snap-fit ​​fastener, and the slot facilitates the installation of the snap-fit ​​fastener inside.

[0012] As a further embodiment of this utility model, a sealing groove is provided on the surface of the other side of the main body of the drum end cover forging, and a sealing gasket is provided inside the sealing groove. The sealing gasket facilitates the sealing between the main body of the drum end cover forging and the drum cylinder.

[0013] As a further embodiment of this utility model, the outer periphery of the drum end cover forging body is provided with limiting holes, and the number of limiting holes is several. The limiting holes facilitate the installation of the drum end cover forging body 1 on the drum cylinder with external bolts.

[0014] This utility model provides a forged end cap for a centrifuge drum, which has the following advantages:

[0015] 1. The centrifuge uses a forged drum end cover. By replacing the components and assemblies, during use, the connecting inner cylinder is inserted into the assembly hole, the snap-fit ​​fastener is snapped into the slot, and the assembly and snap-fit ​​fastener are fixed with an assembly bolt. Then, it is connected to the centrifuge drum. The centrifuge impeller shaft passes through the connecting inner cylinder, thereby preventing the shaft from directly wearing the assembly hole of the drum end cover forging. This avoids the situation where the assembly hole of the centrifuge drum end cover will be severely worn after long-term use, requiring replacement of the entire drum end cover, thus helping to reduce maintenance costs.

[0016] 2. The centrifuge uses a forged drum end cover. Through the setting of the heat dissipation component, the drum end cover generates a lot of heat during high-speed rotation. The thermally conductive silicone can quickly transfer the heat generated by the drum end cover to the heat dissipation fins. The heat dissipation fins increase the contact area with the air, thereby achieving the purpose of rapid heat dissipation. This avoids slow heat dissipation, which would affect the service life of the drum end cover and help improve the stability of equipment operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a centrifuge drum end cap forging, including a drum end cap forging body 1, an assembly hole 2 is provided in the middle of one side of the drum end cap forging body 1, a replacement component 3 is inserted into the assembly hole 2, and heat dissipation components 4 are provided around one side surface of the drum end cap forging body 1.

[0024] The replacement component 3 includes a connecting inner cylinder 301 inserted into the assembly hole 2. One end of the connecting inner cylinder 301 is fixedly connected to an assembly seal 302, and a snap-fit ​​fastener 303 is fixedly sleeved on the surface of the connecting inner cylinder 301. With the replacement component 3 and the assembly 5, in use, the connecting inner cylinder 301 is inserted into the assembly hole 2, the snap-fit ​​fastener 303 is snapped into the slot 8, and the assembly 5 and the snap-fit ​​fastener 303 are fixed with the assembly bolt 6. Then it is connected to the centrifuge drum. The centrifuge blade shaft passes through the connecting inner cylinder 301, thereby preventing the shaft from directly wearing the assembly hole 2 of the drum end cover forging. This avoids the situation where the assembly hole 2 of the centrifuge drum end cover will be worn out after long-term use, requiring the replacement of the entire drum end cover, which helps to reduce maintenance costs.

[0025] The heat dissipation component 4 includes thermally conductive silicone 401, which is disposed around one side of the surface of the drum end cover forging body 1. Heat dissipation fins 402 are provided on one side of the thermally conductive silicone 401. With the heat dissipation component 4, a large amount of heat is generated during the high-speed rotation of the drum end cover in use. The thermally conductive silicone 401 has thermal conductivity and can quickly transfer the heat generated by the drum end cover to the heat dissipation fins 402. The heat dissipation fins 402 increase the contact area with the air, thereby achieving the purpose of rapid heat dissipation. This avoids slow heat dissipation, which would affect the service life of the drum end cover and help improve the stability of equipment operation.

[0026] An assembly 5 is welded to the surface of one end of the drum end cover forging body 1. The surface of the assembly 5 has four threaded holes, and the internal threads of the threaded holes are connected to assembly bolts 6. The assembly bolts 6 serve to fix the parts in place.

[0027] The surface of the snap-fit ​​fastener 303 has four connection holes, which are adapted to the assembly bolt 6. The connection holes facilitate connection with the assembly 5.

[0028] The surface of the heat dissipation fin 402 has four fixing holes, and a fixing post 7 passes through the inside of the fixing holes. One end of the fixing post 7 is threaded to one side of the drum end cover forging body 1. The fixing post 7 facilitates the replacement and maintenance of the heat dissipation fin 402.

[0029] A slot 8 is provided on the other side of the drum end cover forging body 1. The slot 8 is adapted to the snap-fit ​​fastener 303. The slot 8 facilitates the installation of the snap-fit ​​fastener 303 inside.

[0030] A sealing groove is provided on the other side of the main body 1 of the drum end cover forging. A sealing gasket 9 is provided inside the sealing groove. The sealing gasket 9 enhances the sealing between the main body 1 of the drum end cover forging and the drum cylinder.

[0031] The outer periphery of the drum end cover forging body 1 is provided with limiting holes. There are several limiting holes. The limiting holes are used to install the drum end cover forging body 1 on the drum cylinder with external bolts.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When using, insert the connecting inner cylinder 301 into the assembly hole 2, and snap-fit ​​fastener 303 into the slot 8. Use the assembly bolt 6 to fix the assembly 5 and the snap-fit ​​fastener 303, and then connect it to the centrifuge drum. The centrifuge blade shaft passes through the connecting inner cylinder 301.

[0034] The second step: During use, the drum end cover will generate a lot of heat during high-speed rotation. The thermally conductive silicone 401 has thermal conductivity and can quickly transfer the heat generated by the drum end cover to the heat dissipation fins 402. The heat dissipation fins 402 increase the contact area with the air.
