[0002] Centrifugation is to utilize the powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation speed of particles in the liquid, and separate substances with different sedimentation coefficients and buoyancy densities in the sample. Therefore, it is necessary to utilize the centrifuge to generate a powerful centrifugal force to force these particles to overcome diffusion and produce sedimentation motion;

[0003] The horizontal centrifuge utilizes the centrifugal force generated by the high-speed rotating drum to intercept the solid particles in the suspension in the drum and automatically discharge them outside the machine under the action of force; at the same time, under the action of the centrifugal force, the liquid in the suspension is thrown out through the filter medium and the small holes in the drum, so as to achieve the purpose of liquid-solid separation and filtration;

[0004] However, when the above horizontal centrifuge is installed and maintained, the shell needs to be assembled and disassembled. Generally, the fixing method is to use bolts, and tools are required for convenient installation and disassembly. Without tools, it will be very troublesome. Moreover, when some horizontal centrifuges perform solid-liquid separation, the purity of the liquid phase is not enough and there will be some residues, which affect subsequent operations. Therefore, a horizontal centrifuge which is convenient to disassemble is proposed to solve the above problems. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a horizontal centrifuge facilitating disassembly, including a machine body 1. In the middle of the top end of the machine body 1, there is a drum 17. Inside the drum 17, there is a return pipe 19. On the outer wall of the return pipe 19, there is a spiral conveyor 18 fixedly connected. In the middle of the left end of the return pipe 19, there is a feed inlet 4. On the right side of the feed inlet 4, there is a second runner 25. On the lower sides of the left and right ends of the machine body 1, there are support plates 20 fixedly connected. On the top end of the right support plate 20, there is a first motor 2 fixedly connected. At the output end of the first motor 2, there is a first runner 24. The first runner 24 and the second runner 25 are connected by a belt. On the top end of the left support plate 20, there are a second motor 3 and a differential 5 fixedly connected respectively. The differential 5 is coaxial with the return pipe 19. At the output end of the second motor 3, there is a third runner 26. The third runner 26 and the differential 5 are connected by a belt. On the left side of the bottom end of the machine body 1, there is a solid discharge port 10 fixedly connected. On the right side of the bottom end of the machine body 1, there is a liquid discharge port 11 fixedly connected. At the bottom end of the liquid discharge port 11, there is a threaded cap 12 threadedly connected. At the lower front side of the liquid discharge port 11, there is a pipe 21 fixedly connected. At the rear end of the pipe 21, there is a filter screen 13. When the horizontal centrifuge is working, the liquid phase first flows to the bottom from the liquid discharge port 11, and the impurities therein will precipitate at the bottom. Then the liquid phase flows out of the horizontal centrifuge through the pipe 21 below the liquid discharge port 11. During this process, the liquid phase will first pass through the filter screen 13 on the pipe 21 for re - filtration to improve the purity of the liquid phase.

[0025] Refer to Figures 1 - 4 , on the middle of the top end of the machine body 1, there is a housing 6. Around the bottom end of the housing 6, there are side plates 14 fixedly connected. On the front and rear sides of the top end of the machine body 1, there are several locking mechanisms fixedly connected. Each locking mechanism includes a base 9. In the middle of the base 9, there is a column 15 threadedly connected. On the top ends of the bases 9, there are clamping plates 23 fixedly connected. The clamping plates 23 and the columns 15 are fixedly connected. Rotate the column 15 to make it rise, and the clamping plate no longer presses the side plate 14. At this time, the housing 6 can be directly moved. Similarly, the housing 6 can also be quickly fixed, so as to facilitate disassembly.

[0026] On the left and right sides of the top end of the housing 6, there are lifting rings 8 fixedly connected. On the lower front and rear sides of the housing 6, there are grips 7 fixedly connected. At the top end of the column 15, there is an auxiliary rod 16 fixedly connected. At the rear end of the machine body 1, there is a switch button 22. The switch button 22 is electrically connected to the first motor 2 and the second motor 3. At the four corners of the bottom end of the machine body 1, there are machine legs 27 fixedly connected. The return pipe 19, the drum 17, the spiral conveyor 18 and the differential 5 are coaxial. The first runner 24 and the second runner 25 are in interference fit with the belt. The third runner 26 and the differential are in interference fit with the belt. The lifting rings 8 and the grips 7 can facilitate the movement of the housing 6. The auxiliary rod 16 can facilitate the rotation of the column 15. The switch button 22 controls the switch of the horizontal centrifuge.

[0027] Working principle: When disassembling the machine, generally the outer shell 6 needs to be disassembled first. At this time, all the columns 15 are rotated to make the clamping plates 23 all rise and no longer press on the side plates 14. At this time, the outer shell 6 can be moved to proceed with the next disassembly step. When using the machine, when the switch button 22 is pressed, the machine starts. The suspension enters the return pipe 19 from the feed port 4. The centrifugal force generated by the high-speed rotating drum 17 intercepts the solid particles in the suspension in the drum 17 and automatically discharges them to the solid discharge port 10 under the action of force. At the same time, under the action of the centrifugal force, the liquid phase in the suspension is thrown out of the small holes of the drum 17 and flows to the bottom of the liquid discharge port 11. The impurities will also precipitate to the bottom of the liquid discharge port 11. The liquid phase is then filtered through the filter screen 13 on the pipeline 21 and flows out from the pipeline 21. At the end, the threaded cover 12 can be rotated to clean the impurities in the liquid discharge port 11 and the filter screen 13.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
