Description

Technical Field

[0001] The present application relates to the field of centrifuge separation equipment, and in particular to a vacuum-operated high-efficiency disc separator. Background Art

[0002] Disc separator is a common solid-liquid separation equipment, widely used in chemical, pharmaceutical, food and other industries. It uses a rotating disc structure to achieve solid-liquid or liquid-liquid separation, and separates different components in the mixture through the action of centrifugal force and gravity.

[0003] When working, the mixture enters the separator through the feed pipe and then inside the high-speed rotating disc assembly. Due to the centrifugal force generated by the rotation, components of different densities or particle sizes are subjected to different forces and thus separated. During the separation process, solid particles or heavier liquids will settle on the outside of the disc, forming a sediment layer of the solid phase or the heavier liquid phase; while the lighter liquid will move inward to form a clearer liquid phase. As the rotation proceeds, the separated different phases are discharged through the discharge pipes respectively, achieving effective separation of solid-liquid or liquid-liquid.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the friction between the high-speed rotating drum and the surrounding air will generate greater resistance and heat, which will increase the temperature of the drum and cause the temperature of the processed raw materials to increase, thereby posing a safety risk; since the air is driven by the drum, the flow velocity increases, and friction occurs between the air and the stationary casing, which will generate greater resistance and heat, causing the temperature of the casing to rise significantly; the friction of the first two will generate heat, which will become a loss of the disc separator during operation, resulting in a decrease in the overall efficiency of the disc separator.

[0005] If the temperature of an existing disc separator rises during operation, the technology usually used is to add a cooling method such as air cooling or water cooling to the casing or drum part. However, this method only introduces low-temperature fluid from the outside for cooling or heat dissipation, which does not reduce the heat generation from the root source, but will cause greater losses. Summary of the invention

[0006] In order to reduce the friction between the high-speed rotating drum and the surrounding air, and to reduce the safety risk of increased temperature of the processed raw materials due to increased temperature of the drum, the present application provides a vacuum-operated high-efficiency disc separator.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] Disc separator is a common solid-liquid separation equipment, widely used in chemical, pharmaceutical, food and other industries. It uses a rotating disc structure to achieve solid-liquid or liquid-liquid separation, and separates different components in the mixture through the action of centrifugal force and gravity.

[0025] When working, the mixture enters the separator through the feed pipe and then inside the high-speed rotating disc assembly. Due to the centrifugal force generated by the rotation, components of different densities or particle sizes are subjected to different forces and thus separated. During the separation process, solid particles or heavier liquids will settle on the outside of the disc, forming a sediment layer of the solid phase or the heavier liquid phase; while the lighter liquid will move inward to form a clearer liquid phase. As the rotation proceeds, the separated different phases are discharged through the discharge pipes respectively, achieving effective separation of solid-liquid or liquid-liquid.

[0026] With regard to the above-mentioned related technologies, the inventors believe that the friction between the high-speed rotating drum and the surrounding air will generate greater resistance and heat, which will increase the temperature of the drum and cause the temperature of the processed raw materials to increase, thereby posing a safety risk; since the air is driven by the drum, the flow velocity increases, and friction occurs between the air and the stationary casing, which will generate greater resistance and heat, causing the temperature of the casing to rise significantly; the friction of the first two will generate heat, which will become a loss of the disc separator during operation, resulting in a decrease in the overall efficiency of the disc separator.

[0027] If the temperature of an existing disc separator rises during operation, the technology usually used is to add a cooling method such as air cooling or water cooling to the casing or drum part. However, this method only introduces low-temperature fluid from the outside for cooling or heat dissipation, which does not reduce the heat generation from the root source, but will cause greater losses.

[0028] In order to reduce the friction between the high-speed rotating drum and the surrounding air, and to reduce the safety risk of increased temperature of the processed raw materials due to increased temperature of the drum, the present application provides a vacuum-operated high-efficiency disc separator.

[0029] The following is combined with Figure 1 This application is described in further detail.

[0030] The present application embodiment discloses a vacuum-operated high-efficiency disc separator. Figure 1 A vacuum-operated high-efficiency disc separator includes a body 1, a shell 2 fixedly connected to the body 1, and a drum 3 coaxially arranged inside the shell 2. The outer diameter of the drum 3 is smaller than the inner diameter of the shell 2, so that the outer side of the drum 3 and the inside of the shell 2 form a device cavity 4.

[0031] A rotating shaft 11 is disposed on the body 1 relative to the rotating drum 3. The rotating shaft 11 is coaxially disposed with the rotating drum 3 and is fixedly connected to the rotating drum 3. A motor 12 is disposed on one side of the body 1. The motor 12 drives the rotating shaft 11 to rotate, and then the rotating shaft 11 drives the rotating drum 3 to rotate inside the housing 2.

[0032] A vacuum component 5 is provided on one side of the body 1, and the interior of the vacuum component 5 is relatively connected to the interior of the equipment cavity 4. The interior of the equipment cavity 4 is evacuated by the vacuum component 5, thereby reducing the air friction between the drum 3 and the equipment cavity 4 when the drum 3 rotates inside the casing 2.

[0033] The vacuum assembly 5 includes a vacuum pump 51, the air inlet end of the vacuum pump 51 is fixedly connected to a vacuum tube 52, and the end of the vacuum tube 52 facing away from the vacuum pump 51 is fixedly connected to the housing 2, and the vacuum tube 52 is relatively connected to the interior of the equipment cavity 4. The equipment cavity 4 is relatively connected to the air inlet end of the vacuum pump 51 through the vacuum tube 52, and the equipment cavity 4 can be evacuated by the vacuum pump 51.

[0034] A control valve is fixedly connected to the vacuum tube 52, and the control valve is used to control the communication inside the vacuum tube 52. An air pressure detector is also arranged on the vacuum tube 52, and the air pressure detector is fixedly connected to the vacuum tube 52, and the detection end of the air pressure detector is located inside the vacuum tube 52. The air pressure inside the detection tube is detected by the air pressure detector, and since the inside of the vacuum tube 52 is connected with the inside of the device cavity 4, the air pressure inside the vacuum tube 52 is the same as the air pressure inside the device cavity 4.

[0035] Before starting the drum 3 , first open the control valve and start the vacuum pump 51 . The gas inside the equipment cavity 4 is extracted by the vacuum pump 51 , so that the gas pressure inside the equipment cavity 4 is -0.1 MPa, and then start the drum 3 .

[0036] An air intake duct is also provided on the fuselage 1, one end of which is fixedly connected to the fuselage 1, and the interior of the air intake duct is relatively connected to the interior of the equipment cavity 4. A one-way air intake valve is fixedly connected to the side of the air intake duct away from the fuselage 1, the interior of the one-way air intake valve is relatively connected to the interior of the air intake duct, and the air outlet end of the one-way air intake valve is opposite to the air intake duct.

[0037] An air intake valve is fixedly connected to the side of the one-way air intake valve facing away from the fuselage 1, and the air intake valve controls the external gas to enter the inside of the one-way air intake valve.

[0038] The present application can firstly reduce the friction between the high-speed rotating drum 3 and the surrounding air, and can reduce the safety risk of the temperature increase of the processed raw materials caused by the increase in the temperature of the drum 3. Secondly, it can reduce the friction between the air-static casing 2 and reduce the temperature increase of the casing 2. Thirdly, it can reduce the loss of the disc separator during operation and improve the overall efficiency of the disc separator. Fourthly, it can reduce the noise generated by the disc separator during operation, which is beneficial to the environment.
