Description

Technical Field

[0001] This utility model relates to the technical field of horizontal spiral sedimentation centrifuges, and more specifically, to an improved horizontal spiral sedimentation centrifuge. Background Technology

[0002] A horizontal spiral sedimentation centrifuge is a horizontal, spiral-discharge, continuously operating sedimentation device. High-speed rotation generates a strong centrifugal force field. After the solid-liquid mixture enters the centrifuge, under the action of centrifugal force, the denser solid phase material rapidly settles to the inner surface of the drum, achieving solid-liquid stratification. Additionally, the spiral pusher rotates relative to the drum at a certain speed, pushing the solid phase material deposited on the inner surface of the drum to the discharge port at the conical end of the drum. As the solid phase material passes through the conical end of the drum, it undergoes further compression, removing a large amount of water, and finally exits the drum from the discharge port. The liquid phase forms fluid channels between the spiral blades on the inner surface of the solid phase material and flows out of the drum from the overflow port at the cylindrical end of the drum, ultimately achieving continuous separation of the solid and liquid phases.

[0003] Patent application number CN202020862700.2 discloses a horizontal spiral sedimentation centrifuge, including a frame and a drive motor. A first bearing seat and a second bearing seat are respectively installed at both ends of the frame. A rotating drum is arranged between the first bearing seat and the second bearing seat. A hollow spiral pusher is arranged in the middle of the rotating drum. The spiral pusher includes blades fixed on its outer wall. A main pipe is arranged at one end of the spiral pusher, and an air outlet is opened on the outer wall of the other end of the spiral pusher. A discharge port is arranged in the middle of the spiral pusher. A water inlet pipe is arranged at the outer end of the main pipe, and a feed pipe is arranged on one side of the main pipe. When rinsing the inside of the rotating drum, the device simultaneously vents air into the inside of the rotating drum through the air inlet pipe. The air bubbles impact the inner wall of the rotating drum and the spiral pusher, thereby improving the rinsing effect.

[0004] This structure improves cleaning efficiency by creating air holes, but in actual use, the discharge speed is slow, and the separated liquid and solid cannot be discharged quickly. At the same time, if there are metal fragments in the material during the feeding process, it will affect the inside of the centrifuge and the solid sedimentation. Therefore, those skilled in the art have provided an improved horizontal spiral sedimentation centrifuge to solve the above-mentioned problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an improved horizontal spiral sedimentation centrifuge. By setting a manifold ring on the outside of the drum to block the slag discharge tank and the liquid discharge tank, the solids and liquids after centrifugation can be quickly discharged after entering the manifold ring, which improves the discharge efficiency and facilitates subsequent cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] An improved horizontal spiral sedimentation centrifuge includes a frame and a drive assembly mounted on top of it. A housing is installed on the inner wall of the frame, and a drum is rotatably connected inside the housing. The output end of the drive assembly is connected to the left side of the drum. A spiral propeller is installed on the inner wall of the drum. A feed pipe communicating with the inside of the drum is fixedly installed on the right side of the drum. Discharge troughs and liquid discharge troughs are evenly distributed on the outer side of the drum, and both the discharge troughs and liquid discharge troughs communicate with the inside of the drum. Two manifolds are installed on the inner wall of the housing, and the discharge troughs and liquid discharge troughs are located inside the two manifolds respectively. The inner walls of the manifolds are in contact with the outer side of the drum. Discharge pipes and liquid discharge pipes are installed on the left and right manifolds respectively. Both the discharge pipes and discharge pipes penetrate and extend to the outside of the housing. A magnet assembly is installed inside the feed pipe.

The drive motor and its output end are connected inside the differential, and the output end of the differential is connected to the drum.

[0009] As a further description of the above technical solution: the top of the frame is connected to evenly distributed lifting lugs, which are distributed around the top of the frame.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] In this invention, a manifold ring is installed on the outside of the drum to shield the slag discharge tank and the liquid discharge tank, allowing the solids and liquids that have undergone centrifugation to be discharged quickly after entering the manifold ring. This improves the discharge efficiency and facilitates subsequent cleaning. At the same time, a magnetic assembly is installed to adsorb metal debris in the material entering the centrifuge, which can reduce wear on the internal components of the centrifuge, extend the service life of the equipment, and prevent metal particles from interfering with the sedimentation process of the material and affecting the separation efficiency.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4 In this utility model, an improved horizontal spiral sedimentation centrifuge includes a frame 1 and a drive assembly 2 installed on its top. A housing 3 is installed on the inner wall of the frame 1. A drum 4 is rotatably connected inside the housing 3. The output end of the drive assembly 2 is connected to the left side of the drum 4. A spiral propeller 5 is installed on the inner wall of the drum 4. A feed pipe 6 communicating with the inside of the drum 4 is fixedly installed on the right side of the drum 4. A uniformly distributed slag discharge trough 7 and a liquid discharge trough 8 are respectively opened on the outer side of the drum 4. Both the slag discharge trough 7 and the liquid discharge trough 8 are connected to the inside of the drum 4. Two confluence rings 9 are installed on the inner wall of the housing 3. The slag discharge trough 7 and the liquid discharge trough 8 are respectively located inside the two confluence rings 9. The inner wall of the confluence rings 9 is in contact with the outer side of the drum 4. A slag discharge pipe 10 and a liquid discharge pipe 11 are respectively installed on the confluence rings 9 on the left and right sides. Both the liquid discharge pipe 11 and the slag discharge pipe 10 penetrate and extend to the outside of the housing 3. A magnet assembly 12 is provided inside the feed pipe 6.

[0023] The drive assembly 2 includes a drive motor 201 and a differential 202. Both the drive motor 201 and the differential 202 are mounted on the top of the frame 1. The drive motor 201 and its output end are connected inside the differential 202. The output end of the differential 202 is connected to the drum 4.

[0024] Two scrapers 15 are fixedly connected to the outer side of the drum 4, and the scrapers 15 are in contact with the inner wall of the manifold ring 9.

[0025] The magnet assembly 12 includes a threaded sleeve 1201, which is threadedly connected to the inner wall of the feed tube 6. The inner wall of the threaded sleeve 1201 is connected to a uniformly distributed strong magnet 1202. The inner side of the feed tube 6 is provided with an internal thread adapted to the threaded sleeve 1201.

[0026] When material separation is required, before connecting the feed pipe 6 to the conveying pump pipe, the operator connects the threaded sleeve 1201 to the inner wall of the feed pipe 6. At this time, multiple sets of powerful magnets 1202 are distributed in positions close to the pipe wall, so that the magnetic field covers the feed pipe 6. Then, the conveying pump pipe is connected to the feed pipe 6, and then the drive assembly 2 operates, which, in conjunction with the differential 202, causes the drum 4 and the screw propeller 5 to move. At this time, the material enters the screw propeller 5 through the feed pipe 6, and the material is accelerated and rotated into the drum 4. When the material passes through the feed pipe 6, it passes through the threaded sleeve 1201, and the multiple sets of powerful magnets 1202 affect the material. Metal debris is adsorbed. Due to the difference in specific gravity between solids and liquids, solids preferentially and quickly settle on the inner wall of the drum 4 and are then conveyed to the left by the screw propeller 5 until they are discharged from the drum 4 through the slag discharge trough 7. Liquids are discharged through multiple sets of drainage troughs 8 on the other side of the drum 4. Solids and liquids enter the inner confluence rings 9 on both sides and are discharged through the slag discharge pipe 10 and the drainage pipe 11 respectively. As the drum 4 rotates, the scraper 15 realizes the rapid discharge of solids and liquids. During subsequent cleaning, the cleaning fluid is introduced. Due to the close distance of the confluence rings 9, the water flow impact is strong, which improves the cleaning efficiency. The rotation of the scraper 15 also improves the cleaning quality and efficiency.

[0027] In this invention, a manifold ring 9 is installed on the outside of the drum 4 to shield the slag discharge tank 7 and the liquid discharge tank 8, so that the solids and liquids after centrifugation can be quickly discharged after entering the manifold ring 9, which improves the discharge efficiency and facilitates subsequent cleaning. At the same time, the magnetic assembly 12 is installed to adsorb metal debris in the material entering the centrifuge, which can reduce the wear on the internal parts of the centrifuge, extend the service life of the equipment, and prevent metal particles from disturbing the sedimentation process of the material and affecting the separation efficiency.

[0028] Please see Figure 1 The top of the frame 1 is connected to evenly distributed lifting lugs 13, which are distributed around the top of the frame 1.

[0029] In this invention, the evenly distributed lifting lugs 13 facilitate lifting and thus transportation when transporting and hoisting the horizontal spiral sedimentation centrifuge.

[0030] Please see Figure 2 and 3Among them, two sealing rings 14 are rotatably connected to the inner wall of the manifold 9, and the inner side of the sealing ring 14 is connected to the outer side of the drum 4.

[0031] In this invention, the sealing ring 14 can improve the sealing between the manifold ring 9 and the drum 4, and prevent the material from overflowing into the housing 3 when it is inside the manifold ring 9.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
