Description

Technical Field

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

[0002] A horizontal centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. A horizontal centrifuge mainly consists of a high-speed rotating drum, a screw conveyor with a hollow shaft rotating in the same direction as the drum but at a slightly lower speed, and a differential gear. Horizontal centrifuges have an unparalleled price advantage compared to similar products. Furthermore, they feature advanced design technology, automatic continuous operation, large processing capacity, and high raw material utilization. Horizontal centrifuges are mainly suitable for industries such as chemical, medical, food, and starch processing.

[0003] However, traditional horizontal centrifuges still have certain shortcomings in use: 1. During centrifugation, solid particles tend to accumulate inside the machine, affecting the centrifugation effect and potentially causing equipment blockage. This increases maintenance costs and production downtime. Furthermore, particulate impurities are difficult to settle, reducing the machine's practicality.

[0004] 2. Traditional centrifuges are not suitable for filtration and separation. During centrifugation, due to the centrifugal force, solid particles are often thrown against the inner wall of the centrifuge. If these particles cannot be discharged in time and effectively, they will accumulate inside the machine, which will not only affect the centrifugation effect, but may also cause equipment blockage. Summary of the Invention

[0005] The purpose of this invention is to provide a horizontal spiral sedimentation centrifuge to solve the problems mentioned in the background art, such as the accumulation of solid particles inside the centrifuge during the centrifugation process, which affects the centrifugation effect and may even cause equipment blockage, increasing maintenance costs and production downtime. Furthermore, the particulate impurities are not easily settled, reducing practicality. Traditional centrifuges are not suitable for filtration and separation. During centrifugation, due to centrifugal force, solid particles are often thrown against the inner wall of the centrifuge. If these particles cannot be discharged in a timely and effective manner, they will accumulate inside the centrifuge, not only affecting the centrifugation effect but also potentially causing equipment blockage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A horizontal spiral sedimentation centrifuge includes a mounting base plate, a centrifuge body mounted on top of the mounting base plate, a support shaft seat fixedly connected to the top of the mounting base plate, an outer side surface of the centrifuge body rotatably connected to the mounting base plate via the support shaft seat, a centrifuge cylinder fixedly connected inside the centrifuge body, a filter screen mounted on the outer surface of the centrifuge cylinder, a sedimentation zone between the centrifuge cylinder and the filter screen, a motor base fixedly connected to the side of the mounting base plate, a drive motor mounted on top of the motor base, and the output end of the drive motor extending into the support shaft seat and fixedly connected to the centrifuge body via a coupling.

[0007] As a preferred embodiment of this utility model, a mounting frame is provided at the bottom of the mounting base plate, and a piston pushing centrifuge and a rotary motor are respectively mounted on the top of the mounting frame. A drive shaft is fixedly connected to the output end of the rotary motor, and a spiral pushing blade is fixedly connected to the end of the drive shaft.

The spiral pusher blade is rotatably connected to the guide cylinder. The end of the guide cylinder is fixedly connected to the piston pusher centrifuge. The guide cylinder and the piston pusher centrifuge are in communication.

[0009] As a preferred embodiment of this utility model, a discharge pipe is fixedly connected to the bottom of the centrifuge body, the discharge pipe is connected to the centrifuge body, and a loading hole is opened at the end of the centrifuge body.

[0012] As a preferred embodiment of this utility model, a discharge pipe is fixedly connected to the side of the piston pusher centrifuge, and the discharge pipe communicates with the piston pusher centrifuge.

[0013] As a preferred embodiment of this utility model, the outer surface of the centrifuge body is coated with an anti-corrosion solution, and the guide cylinder is made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by using a centrifuge body, a drive motor, a coupling, a centrifuge drum, and a settling zone in combination, solid particles can be effectively separated from liquids. The centrifuge body is equipped with a centrifuge drum, and the drive motor drives the centrifuge body and the centrifuge drum to rotate through the coupling. A settling zone is set between the inner wall of the centrifuge drum and the external filter screen for the settling of solid particles. During the centrifugation process, due to the centrifugal force, solid particles are thrown towards the inner wall of the centrifuge drum and enter the settling zone. After settling, the particles gradually accumulate and are discharged through the discharge pipe, avoiding the accumulation of solid particles inside the machine body and improving the centrifugation effect and the practicality of the equipment.

[0015] 2. In this utility model, by setting up a rotary motor, a feeding pipe, a guide cylinder, a spiral pusher blade, a piston pusher centrifuge, and a discharge pipe, the rotary motor drives the spiral pusher blade to rotate inside the guide cylinder, feeding the material to be separated into the guide cylinder through the feeding pipe. Under the action of the spiral pusher blade, the material is evenly guided into the piston pusher centrifuge. After centrifugal separation, the solid particles are pushed to one end of the piston pusher centrifuge and discharged through the discharge pipe, while the liquid flows out from the other end of the piston pusher centrifuge, realizing the effective separation of solids and liquids, and further improving the centrifugation effect and working efficiency.

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 protection scope of the present utility model.

[0019] For examples, please refer to Figure 1 This utility model provides a technical solution: A horizontal spiral sedimentation centrifuge includes a mounting base plate 15, a centrifuge body 1 on top of the mounting base plate 15, a support shaft seat 4 fixedly connected to the top of the mounting base plate 15, the outer side surface of the centrifuge body 1 being rotatably connected to the mounting base plate 15 via the support shaft seat 4, a centrifuge cylinder 18 fixedly connected inside the centrifuge body 1, a filter screen on the outer surface of the centrifuge cylinder 18, a sedimentation zone 17 between the centrifuge cylinder 18 and the filter screen, a motor base 5 fixedly connected to the side of the mounting base plate 15, a drive motor 2 mounted on top of the motor base 5, the output end of the drive motor 2 extending into the support shaft seat 4 and fixedly connected to the centrifuge body 1 via a coupling 6, a discharge pipe 7 fixedly connected to the bottom of the centrifuge body 1, the discharge pipe 7 communicating with the centrifuge body 1, and a feeding hole at the end of the centrifuge body 1.

[0020] The rotary motor 11 drives the centrifuge drum 18 to rotate at a certain speed. Under the action of centrifugal force, the material is divided into a sedimentation zone and a clarification zone in the centrifuge drum 18, and the heavy particles settle into the sedimentation zone 17.

[0021] In this embodiment, as Figure 1 As shown, a mounting bracket 13 is provided at the bottom of the mounting base plate 15. A piston-push centrifuge 9 and a rotary motor 11 are respectively mounted on the top of the mounting bracket 13. A drive shaft 12 is fixedly connected to the output end of the rotary motor 11. A spiral pusher blade 8 is fixedly connected to the end of the drive shaft 12. A guide cylinder 16 is fixedly connected to the top of the mounting bracket 13. The spiral pusher blade 8 passes through the guide cylinder 16 and extends into the guide cylinder 16. The spiral pusher blade 8 is rotatably connected to the guide cylinder 16. The end of the guide cylinder 16 is fixed to the piston-push centrifuge 9. The guide cylinder 16 is connected to the piston pusher centrifuge 9. The top of the guide cylinder 16 is fixedly connected to the feed pipe 10, which is connected to the guide cylinder 16. The feed pipe 10 is located at the bottom of the discharge pipe 7. The bottom of the mounting base plate 15 is provided with a mounting base 3, which is threadedly connected to the mounting base plate 15 by fixing bolts. The side of the piston pusher centrifuge 9 is fixedly connected to the discharge pipe 14, which is connected to the piston pusher centrifuge 9. The outer surface of the centrifuge body 1 is coated with an anti-corrosion solution. The guide cylinder 16 is made of stainless steel.

[0022] In this process, the material is uniformly guided into the piston-pushing centrifuge 9 under the action of the spiral pusher blade 8. At the same time, the spiral pusher blade 8 rotates in the centrifuge cylinder 18, pushing the settled particles to the discharge pipe 7 for discharge, thus achieving continuous separation operation.

[0023] The working process of this utility model is as follows: When the horizontal spiral sedimentation centrifuge designed using this solution is in operation, first check whether the device is working properly and ensure that all parts are intact and undamaged, without any looseness or damage. Subsequently, the material to be processed is fed into the centrifuge body 1, and the drive motor 2 is started. The drive motor 2 drives the centrifuge drum 18 to rotate at a certain speed. Under the action of centrifugal force, the material is divided into a sedimentation zone and a clarification zone in the centrifuge drum 18. The heavy particles settle into the sedimentation zone 17, while the light liquid is discharged through the discharge pipe 14. The rotary motor 11 drives the spiral pusher blade 8 to rotate in the guide cylinder 16, which feeds the material to be separated into the guide cylinder 16 through the feed pipe 10. Under the action of the spiral pusher blade 8, the material is evenly guided into the piston pusher centrifuge 9. At the same time, the spiral pusher blade 8 rotates in the centrifuge drum 18, pushing the settled particles to the discharge pipe 7 for discharge, thus realizing continuous separation operation. Throughout the process, the guide cylinder 16 plays a guiding and supporting role to ensure that the material rotates stably in the centrifuge drum 18. By adjusting the speed of the rotary motor 11 and the pushing speed of the spiral pusher blade 8, the separation effect and separation efficiency of different materials can be optimized.
