Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a horizontal spiral sedimentation centrifuge. Background Technology

[0002] A centrifuge is a laboratory or industrial device that uses centrifugal force to separate substances. By rotating at high speed, substances of different densities and sizes will have different sedimentation velocities in the rotating system, thereby achieving separation, purification or concentration. It is widely used in fields such as biology, chemical engineering, and medicine. The core principle is to convert the centrifugal force generated by the rotational motion into the sedimentation force of the substances, replacing gravity to achieve faster and more efficient separation. The separation effect can be controlled by adjusting the rotation speed.

[0003] When the centrifuge is working, the solid-liquid mixture to be separated is conveyed to the hollow shaft inside the equipment through the feed pipe, and then evenly enters the high-speed rotating drum through the feed hole on the hollow shaft. The material is synchronously subjected to centrifugal force with the drum. The drum rotates at high speed, causing the solid particles in the mixture to settle to the inner wall of the drum, forming a solid sludge layer that adheres tightly to the inner wall, while the less dense liquid remains inside the sludge layer, forming a clear liquid layer, thus achieving solid-liquid separation.

[0004] When using a horizontal spiral sedimentation centrifuge, if the material to be processed contains large impurities, direct entry into the equipment will cause blockage, forcing a shutdown for cleaning.

[0005] Therefore, a horizontal spiral sedimentation centrifuge is proposed to address the above problems. Utility Model Content

The buffer tube is connected to the feed inlet; a second motor is installed on the top of the buffer tube; a blade is fixedly connected to the output end of the second motor; a heating element is fixedly connected to the surface of the buffer tube; a connecting pipe is fixedly connected to one side of the buffer tube; and a cover is hinged to the top of the frame. By driving the blade to rotate with the second motor, the material entering the buffer tube through the connecting pipe is cut into small particles, which can reduce material blockage at the feed inlet or getting stuck in the drum, and increase the smoothness of separation. At the same time, the heating element on the surface of the buffer tube can preheat the material, reduce viscosity, reduce material agglomeration and sticking to the wall, and increase material uniformity.

[0008] Preferably, an electro-permanent magnet is embedded in the top of the frame; a controller is installed on one side of the frame; the controller is electrically connected to the drive assembly; by rotating the controller, the electro-permanent magnet is attracted to the cover, eliminating the traditional bolt fixing step, increasing operational convenience, and improving separation efficiency. At the same time, the drive assembly is electrically connected to the controller, so the drive assembly cannot be opened when the cover is not closed, forming a safety lock, reducing the risk of accidents caused by accidental activation of the drive assembly, and increasing the safety of the equipment.

[0009] Preferably, the bottom of the support leg is fixedly connected to an adjusting pad; the bottom of the frame is fixedly connected to a level; by observing the level, the height of the adjusting pad is adjusted to ensure that the frame remains level, reduce the deviation of the rotating axis of the drum from the central axis perpendicular to the ground, reduce the violent shaking of the entire equipment, reduce the equipment offset or tipping, and at the same time reduce the wear of internal components of the drive assembly and increase service life.

[0010] Preferably, multiple rollers are rotatably connected to the surface of the frame; the rollers are arranged in contact with the drum; by setting rollers on the inner wall of the frame and having them in contact with the drum, and rotating synchronously with the drum, additional support points can be provided, dispersing the overall load-bearing pressure of the drum from both ends, reducing deformation or breakage caused by stress concentration at both ends of the drum, reducing wear on the drum surface, extending service life, and reducing replacement costs.

[0011] Preferably, a plurality of rubber pads are fixedly attached to the surface of the frame; the rubber pads are correspondingly arranged with the frame; by setting rubber pads on the top of the frame, the cover can be buffered when it is closed with the frame, reducing the impact force and noise generated by the closing, improving the operating environment, and at the same time weakening the vibration transmission during equipment operation.

[0012] Preferably, the inner wall of the machine hood is provided with an anti-sticking layer; the anti-sticking layer is provided corresponding to the slag outlet; by providing an anti-sticking layer on the inner wall of the machine hood, the adhesion of waste residue to the inner wall of the machine hood can be reduced, gradually forming a slag layer of uneven thickness, reducing the waste residue discharge speed, while reducing the number of shutdowns for cleaning, and increasing continuous production efficiency.

[0013] The advantages of this utility model are:

[0014] 1. The horizontal spiral sedimentation centrifuge of this utility model cuts the material entering the buffer tube from the connecting pipe into small particles by rotating the blade driven by the second motor.

At the same time, the heating plates on the surface of the buffer tube can preheat the material, reduce viscosity, reduce material agglomeration and sticking to the wall, and increase material uniformity.

[0015] 2.

At the same time, the drive component is electrically connected to the controller, so the drive component cannot be opened when the hood is not closed, forming a safety lock, reducing the risk of accidents caused by accidental start of the drive component, and increasing the safety of the equipment.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a horizontal spiral sedimentation centrifuge includes a frame 1; multiple support legs 11 are fixedly connected to the bottom of the frame 1; a drive assembly 12 is installed on the top of the support legs 11; a rotating drum 13 is fixedly connected to the output end of the drive assembly 12; multiple slag outlets 14 are fixedly connected to one side of the rotating drum 13; multiple liquid outlets 15 are fixedly connected to the other side of the rotating drum 13; a feed inlet 16 is rotatably connected to one side of the rotating drum 13; the feed inlet 16 is located on the side near the liquid outlets 15; and a [missing information - likely a device or component] is installed at the end of the feed inlet 16. Pump body 17; a buffer tube 18 is fixedly connected to the top of the pump body 17; the buffer tube 18 is connected to the feed inlet 16 through the pump body 17; a second motor 19 is installed on the top of the buffer tube 18; a blade 110 is fixedly connected to the output end of the second motor 19; a heating element 111 is fixedly connected to the surface of the buffer tube 18; a connecting pipe 112 is fixedly connected to one side of the buffer tube 18; a cover 113 is hinged to the top of the frame 1; during operation, the cover 113 is rotated to fit against the top of the frame 1, and fixed with bolts or other means, connecting... Pipe 112 is connected to the feeding device, allowing material to be conveyed into the buffer tube 18. The second motor 19 is turned on to drive the blade 110 to rotate, cutting large pieces of material. At the same time, the heating element 111 is turned on to heat the buffer tube 18. The material conveying rate is controlled by the pump body 17. After the material enters the drum 13 through the feed inlet 16, the drive assembly 12 is turned on to make the drum 13 rotate, separating the material inside using centrifugal force. The spiral pusher inside the drum 13 pushes the solid particles towards the slag outlet 14, while the liquid flows towards the liquid outlet. At port 15, separation is completed. The drive assembly 12 includes a rotary motor and a differential. The rotary motor is connected to the drum 13, and the differential is connected to the screw feeder. By driving the blade 110 to rotate through the second motor 19, the material entering the buffer tube 18 through the connecting tube 112 is cut into small particles. This can reduce the material from clogging the feed port 16 or getting stuck in the drum 13, and increase the smoothness of separation. At the same time, the heating plate 111 on the surface of the buffer tube 18 can preheat the material, reduce viscosity, reduce material agglomeration and sticking to the wall, and increase material uniformity.

[0026] like Figures 1 to 3As shown, an electro-permanent magnet 2 is embedded in the top of the frame 1; a controller 21 is installed on one side of the frame 1; the controller 21 is electrically connected to the drive assembly 12; during operation, the cover 113 is rotated so that it contacts the top of the frame 1, the controller 21 is connected to the power supply, the power is turned on, and then the controller 21 is rotated so that the current passes through the electro-permanent magnet 2 and the drive assembly 12. After the electro-permanent magnet 2 is energized, it generates magnetism and attracts the cover 113. By rotating the controller 21, the electro-permanent magnet 2 attracts the cover 113, eliminating the traditional bolt fixing step, increasing the convenience of operation, and improving the separation efficiency. At the same time, the drive assembly 12 is electrically connected to the controller 21. When the cover 113 is not closed, the drive assembly 12 cannot be opened, forming a safety lock, reducing the risk of accidents caused by the accidental opening of the drive assembly 12, and increasing the safety of the equipment.

[0027] like Figures 1 to 3 As shown, the bottom of the support leg 11 is fixedly connected to an adjusting foot 3; the bottom of the frame 1 is fixedly connected to a level 31; during operation, observe the position of the bubble inside the level 31 and adjust the height of the adjusting foot 3 individually to keep the frame 1 horizontal. By observing the level 31 and adjusting the height of the adjusting foot 3, the frame 1 is kept horizontal, reducing the deviation of the rotation axis of the drum 13 from the central axis perpendicular to the ground, reducing the violent shaking of the entire equipment, reducing equipment offset or tipping, and at the same time reducing the wear of the internal parts of the drive assembly 12 and increasing its service life.

[0028] like Figure 3 As shown, multiple rollers 4 are rotatably connected to the surface of the frame 1; the rollers 4 are arranged in contact with the drum 13; during operation, the rollers 4 contact the surface of the drum 13, providing additional support points and dispersing the pressure at both ends of the drum 13. When the drum 13 rotates, the rollers 4 rotate using friction, reducing wear on the surface of the drum 13. By setting rollers 4 on the inner wall of the frame 1 and contacting the drum 13, and rotating synchronously with the drum 13, additional support points can be provided, dispersing the overall load-bearing pressure of the drum 13 from both ends, reducing deformation or breakage caused by stress concentration at both ends of the drum 13, reducing wear on the surface of the drum 13, extending service life, and reducing replacement costs.

[0029] like Figures 1 to 3 As shown, multiple rubber pads 5 are fixed to the surface of the frame 1; the rubber pads 5 are correspondingly arranged with the frame 1; during operation, when the cover 113 contacts the top of the frame 1, the rubber pads 5 use their own elasticity to reduce the impact force on the contact surface, and at the same time generate elastic deformation to fill the gap between the two, reducing material leakage. By setting the rubber pads 5 on the top of the frame 1, the cover 113 can be buffered when it is closed with the frame 1, reducing the impact force and noise generated by the closing, improving the operating environment, and at the same time weakening the vibration transmission during equipment operation.

[0030] like Figures 1 to 4As shown, the inner wall of the machine cover 113 is provided with an anti-sticking layer 6; the anti-sticking layer 6 is correspondingly provided with the slag outlet 14; during operation, when slag is discharged from the slag outlet 14, the waste slag will be thrown outward by the centrifugal force generated by the rotation of the drum 13. The anti-sticking layer 6 of the machine cover 113 reduces the adhesion of waste slag to the inner wall of the machine cover 113, reducing the difficulty of cleaning. By setting the anti-sticking layer 6 on the inner wall of the machine cover 113, the adhesion of waste slag to the inner wall of the machine cover 113 can be reduced, gradually forming a slag layer of uneven thickness, reducing the waste slag discharge speed, reducing the number of shutdowns for cleaning, and increasing continuous production efficiency.

[0031] Working principle: By rotating the machine cover 113 to fit against the top of the frame 1 and fixing it with bolts or other means, the connecting pipe 112 is connected to the feeding device, allowing the material to be conveyed into the buffer tube 18. The second motor 19 is turned on to drive the blade 110 to rotate, cutting large pieces of material. At the same time, the heating element 111 is turned on to heat the buffer tube 18. The material conveying rate is controlled by the pump body 17. After the material enters the drum 13 through the feed port 16, the drive assembly 12 is turned on to make the drum 13 rotate, separating the material inside using centrifugal force. The spiral pusher inside the drum 13 pushes the solid particles towards the slag outlet 14, while the liquid flows towards the liquid outlet 15, completing the separation. The drive assembly 12 includes a rotary motor and a differential. The rotary motor is connected to the drum 13, and the differential is connected to the spiral pusher. Rotating the machine cover 113 to contact the top of the frame 1, the controller 21 and... Connect the power supply and turn it on. Then rotate the controller 21 to allow current to flow through the electro-permanent magnet 2 and the drive assembly 12. After the electro-permanent magnet 2 is energized, it generates magnetism and attracts the machine cover 113. Observe the position of the bubble inside the level 31 and adjust the height of the adjusting pads 3 individually to keep the frame 1 horizontal. The roller 4 contacts the surface of the drum 13, providing additional support points and dispersing the pressure at both ends of the drum 13. When the drum 13 rotates, the roller 4 rotates using friction to reduce wear on the surface of the drum 13. When the machine cover 113 contacts the top of the frame 1, the rubber pad 5 uses its own elasticity to reduce the impact force on the contact surface and at the same time generates elastic deformation to fill the gap between the two, reducing material leakage. When slag is discharged at the slag outlet 14, the waste slag will be thrown out in all directions by the centrifugal force generated by the rotation of the drum 13. The machine cover 113 uses the anti-stick layer 6 to reduce the adhesion of waste slag to the inner wall of the machine cover 113, reducing the difficulty of cleaning.
