Description

Technical Field

[0001] This utility model relates to the technical field of spiral slag discharge devices, and in particular to a spiral slag discharge device for a horizontal spiral unloading sedimentation centrifuge. Background Technology

[0002] Horizontal screw discharge sedimentation centrifuges are widely used in the field of industrial solid-liquid separation. Their screw discharge device plays a key role in efficiently discharging solid materials, silt, etc. from the drum after centrifugation and sedimentation.

[0003] The device mainly consists of a screw conveyor and a rotating drum. The screw conveyor is located inside the rotating drum, and its screw blades are closely attached to the inner wall of the drum. There is a certain speed difference between the two. When working, the material enters the high-speed rotating drum. Under the action of strong centrifugal force, the liquid and solid are separated. The solid particles settle to the drum wall. The screw conveyor rotates at a relatively slow speed, pushing the solid towards the slag discharge port to achieve slag discharge.

[0004] However, existing spiral slag discharge devices lack effective anti-sludge and sand adhesion designs. During operation, sludge and sand adhere to the inside of the machine body and accumulate on the inner wall of the drum, altering its surface properties and affecting the material separation effect under centrifugal force, thus reducing separation accuracy. In the gap between the spiral conveyor and the drum, sludge and sand adhesion increases frictional resistance, exacerbates component wear, increases energy consumption, and reduces equipment lifespan. In other parts of the machine body, such as near the feed and discharge channels, sludge and sand adhesion hinders material flow, causing uneven feeding, poor discharge, or even blockage. Cleaning is extremely inconvenient, increasing maintenance costs and downtime, and reducing production efficiency. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a spiral slag discharge device for a horizontal spiral discharge sedimentation centrifuge, aiming to improve the lack of effective anti-sludge and sand adhesion design in the existing technology, which causes uneven feeding, poor drainage, or even blockage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1 to 4 One embodiment of this utility model includes a machine body 1 and a receiving plate 16. A base plate 3 is provided on the lower side of the outer wall of the machine body 1. A motor 4 is fixedly connected to the top wall of the base plate 3. A rotating wheel 5 is fixedly connected to the output end of the motor 4. Fixing plates 8 are fixedly connected to both sides of the top wall of the base plate 3. The machine body 1 is the core component, which houses the material handling components. The receiving plate 16 supports the machine body 1 and prevents mud and sand from adhering through related components. The base plate 3 provides a stable mounting foundation for components such as the motor 4. The motor 4 provides power to drive the rotating wheel 5 to rotate. The fixing plates 8 are used to install and fix related components such as vibration components to ensure stable operation and functional realization of the device.

[0024] A vibration assembly is provided on the front side of the fixed plate 8. A linear array of cylinders 12 are fixedly connected to the top wall of the base plate 3. Fixed rings 13 are fixedly connected to the top and bottom sides of the cylinders 12. Rebound assemblies are provided on both sides of the top wall of the base plate 3. Springs 17 are fixedly connected to both sides of the top wall of the receiving plate 16. The vibration assembly generates vibration with the power of the motor 4, causing the receiving plate 16 to vibrate, which in turn drives the body 1 to vibrate to prevent mud and sand from adhering. The cylinders 12 and fixed rings 13 provide stable support and sliding guidance for the receiving plate 16. The rebound assembly and springs 17 work together to enhance the vibration effect of the receiving plate 16 and buffer its vibration, ensuring the smooth operation of the device and reducing mud and sand residue.

[0025] A quick-release mechanism 2 is installed on the rear side of the machine body 1. The quick-release mechanism 2 is used to quickly open the spiral slag discharge device. The vibration component includes a rotating column 7, which is fixedly connected to the output end of the motor 4. A disc 9 is fixedly connected to the outer wall of the rotating column 7. The rotating column 7 is fixedly connected to the lower middle side of the outer wall of the disc 9. The quick-release mechanism 2 facilitates the quick opening of the machine body 1, which is conducive to the internal maintenance, repair and cleaning of the equipment. The rotating column 7 transmits the power of the motor 4 to the disc 9, causing the disc 9 to rotate. The disc 9 and other components work together to produce a vibration effect, which drives the machine body 1 to vibrate, preventing mud and sand from adhering inside the machine body 1 and ensuring the efficient and stable operation of the spiral slag discharge device.

[0026] A sliding block 10 is fixedly connected to the bottom wall of the receiving plate 16. The sliding block 10 is slidably connected to the disc 9. The receiving plate 16 is fixedly and slidably connected to the top of the cylinder 12. The rebound assembly includes multiple hooks 14. Two hooks 14 are fixedly connected to the opposite surfaces of the receiving plate 16 and the base plate 3. A spring 15 is fixedly connected to the opposite surfaces of the hooks 14. A rotating wheel 11 is rotatably connected to the outer wall of the fixed plate 8. The rotating wheel 11 and the rotating wheel 15 are rotatably connected through the transmission belt 6. A vibration assembly is installed on the front side of the rotating wheel 11. The sliding block 10 is slidably connected to the disc 9, so that the disc 9 can drive the receiving plate 16 to vibrate when it rotates. The cylinder 12 provides guiding support for the sliding of the receiving plate 16. The spring 15 is connected to the receiving plate 16 and the base plate 3 through the hooks 14, which assists the receiving plate 16 in rebounding and enhances the vibration effect. The rotating wheel 11 and the rotating wheel 15 are driven by the transmission belt 6 to drive the vibration assembly on their front side, so that the vibration assemblies on both sides work together to make the vibration of the receiving plate 16 more uniform and stable.

[0027] The quick-release mechanism 2 includes a fixing block 201, which is fixedly connected to both sides of the outer wall of the body 1. Square plates 202 are fixedly connected to both sides of the outer wall of the fixing block 201. Connecting columns 203 are fixedly connected to the opposite surfaces of the two square plates 202. Locking blocks 204 are slidably connected to both sides of the outer wall of the connecting columns 203. The fixing block 201 provides a fixed base for the square plate 202, the square plate 202 supports the connecting columns 203, and the connecting columns 203 provide a sliding track for the locking blocks 204. These structures together constitute the basic frame of the quick-release mechanism 2, realizing the quick locking and unlocking of the body 1 and the fixing plate 18.

[0028] Two springs 205 are fixedly connected to the opposite surfaces of the two locking blocks 204. A pressing plate 206 is fixedly connected to the outer wall of the locking blocks 204. A fixed plate 18 is provided at one end of the machine body 1. Two locking holes 207 are opened on both sides of the fixed plate 18. The locking holes 207 engage with the locking blocks 204. The springs 205 provide elastic force for the locking blocks 204 so that they are locked into the locking holes 207 in the normal state, locking the machine body 1 and the fixed plate 18. The pressing plate 206 facilitates the operation of the locking blocks 204 to slide out of the locking holes 207 to unlock, realizing convenient switching of the connection state between the machine body 1 and the fixed plate 18, which is convenient for equipment maintenance.

[0029] Working principle: Motor 4 starts, driving rotating wheel 5 to rotate. This, in turn, causes rotating wheel 11 to rotate synchronously via conveyor belt 6. The output of motor 4 is also connected to rotating column 7, which drives rotating disc 9. Since the sliding block 10 at the bottom of receiving disc 16 is slidably connected to disc 9, and receiving disc 16 is slidably connected to the top of column 12, the rotation of disc 9 causes vibration in receiving disc 16. During this process, when receiving disc 16 is lifted by the rotation of disc 9, spring 15 is stretched, storing elastic potential energy. When the disc 9 rotates to a certain position and its effect on the top of the receiving disc 16 weakens, the spring 15 releases its elastic potential energy, pulling the receiving disc 16 downwards. This process is repeated, causing the receiving disc 16 to vibrate continuously. The machine body 1 is placed above the receiving disc 16. Under the vibration of the receiving disc 16, solid materials such as mud and sand inside the machine body 1 are not easily attached to the inside of the machine body. The spring 317 plays an auxiliary role in buffering and stabilizing the relative position of the receiving disc 16 and the machine body 1. In addition, when it is necessary to maintain or clean the inside of the spiral slag discharge device;

[0030] Furthermore, a quick-release device is installed between the body 1 and the fixed plate 18. When the quick-release mechanism 2 is working, under normal conditions, the locking block 204 is engaged in the locking hole 207 of the fixed plate 18 under the action of the second spring 205, firmly connecting the body 1 and the fixed plate 18. When it is necessary to open the device, press the pressing plate 206, which drives the locking block 204 to slide outward along the connecting column 203. The second spring 205 is compressed, and the locking block 204 disengages from the locking hole 207, releasing the lock between the body 1 and the fixed plate 18. The body 1 can then be opened. After maintenance and other operations are completed, the body 1 is reset, the pressing plate 206 is released, and the second spring 205 rebounds, causing the locking block 204 to engage in the locking hole 207 again, relocking the body 1 and the fixed plate 18. This ensures the stability of the device structure and facilitates the quick disassembly and installation of the body 1, which is beneficial for equipment maintenance and repair.
