Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral classifier technology, and in particular to a spiral classifier that is easy to feed. Background Technology
[0002] Spiral classifiers are widely used in the mineral processing industry, mainly for particle size classification of mineral particles and desliming and dewatering of slurry. A typical application scenario is in wet mineral processing, where slurry that has been crushed by ball mill is classified. It utilizes the principle that solid particles have different settling velocities in a liquid. The rotating spiral blades push the coarse particles that have settled at the bottom of the tank upwards and back to the mill for re-grinding, while the fine particles that meet the particle size requirements are discharged from the overflow weir with the slurry flow into the next process. Currently, spiral classifiers cannot control the flow rate of slurry at the slurry outlet during operation. A smaller outlet may result in a slower discharge speed, leading to blockages, while a larger outlet may cause incomplete separation, resulting in poor separation efficiency. Furthermore, during the discharge process, silt and sand in the slurry may accumulate at the outlet, which may affect the slurry discharge over time and requires manual shutdown and cleaning, which is very troublesome.

Detailed Implementation
[0012] Reference Figures 1-5 A spiral classifier for easy material feeding includes: An inclined support 1 is provided, on which a spiral classifier body 2 is fixedly installed. The spiral classifier body 2 consists of a frame, spiral blades, and a discharge port. The slurry is screened by the rotation of the spiral blades. This is existing technology and will not be described in detail. A servo motor 3 is fixedly installed on the side wall of the spiral classifier body 2. The servo motor 3 is fixedly connected to the spiral blades and controls the rotation of the spiral blades. A dark plate 20 is slidably connected to the side wall of the spiral classifier body 2. A protrusion 21 is fixedly connected to the side wall of the dark plate 20. Four fixing blocks are fixedly connected to the side wall of the spiral classifier body 2. The four fixing blocks are in pairs. Each pair of fixing blocks is rotatably connected to a locking rod 22. A handle 24 is fixedly connected to the side wall of the dark plate 20. By pulling open the dark plate 20 with the handle 24, the slurry can flow directly out from the dark plate 20, which is convenient for cleaning the slurry inside the spiral classifier body 2. The locking rod 22 can block the protrusion 21, thereby fixing the dark plate 20 and preventing the slurry from being exposed due to vibration. An adjustment structure is installed on the spiral classifier body 2. This structure includes a control motor 4 fixedly mounted on the upper side of the spiral classifier body 2. A protective shell 23 is fixedly mounted on the upper side of the spiral classifier body 2. The outer wall of the protective shell 23 has ventilation holes, and the upper side has a shielding curtain to reduce the entry of mud or water into the protective shell 23. The protective shell 23 protects the control motor 4. A bidirectional screw 5 is rotatably connected to the side wall of the spiral classifier body 2. The output end of the control motor 4 is connected to the bidirectional screw 5 via a pulley assembly 6. The pulley assembly 6 consists of two pulleys and a belt, transmitting power from the output end of the control motor 4 to the bidirectional screw 5. A rubber collar is provided at the rotatable connection between the bidirectional screw 5 and the spiral classifier body 2, thereby allowing the bidirectional screw 5 to rotate smoothly. Under normal conditions, it has a certain frictional force to prevent rotation. The outer thread of the bidirectional screw 5 is connected to two baffles 7. When the bidirectional screw 5 rotates, the two baffles 7 can move towards each other, or move inward or outward at the same time. Both baffles 7 are slidably connected to the spiral classifier body 2. Both baffles 7 have locking blocks 8 fixedly connected to their side walls. Both baffles 7 have notches on their side walls. Both notches have buffer plates 9 slidably connected to them. Multiple springs 10 are fixedly connected between the buffer plates 9 and the baffles 7. When fully closed, the locking block 8 of one baffle 7 can be locked into the notch of the other baffle 7, and the other baffle 7 can also be locked in the same way. When locked in, the buffer plates 9 can be squeezed, thereby improving the sealing effect and reducing the entry of mud.
[0013] The spiral classifier body 2 is equipped with a reciprocating structure, which includes a support plate 11 fixedly connected to the side wall of the spiral classifier body 2. A reciprocating screw 12 is rotatably connected to the side wall of the support plate 11. The reciprocating screw 12 is connected to the bidirectional screw 5 through a pulley assembly 2 13. The pulley assembly 2 13 also consists of two pulleys and a belt, which can transmit the power of the bidirectional screw 5 to the reciprocating screw 12. A sliding rod 14 is slidably connected to the side wall of the support plate 11. A reciprocating block 15 is rotatably connected to the upper side of the sliding rod 14. The reciprocating block 15 matches the reciprocating screw 12 and can slide along the reciprocating groove on the outer side of the reciprocating screw 12, thereby driving the sliding rod 14 to reciprocate. A cleaning plate 16 is fixedly connected to the lower side of the sliding rod 14. The side wall of the cleaning plate 16 is a sloping surface, which can effectively clean mud and sand.
[0014] A water pump 17 is fixedly installed on the upper side of the spiral classifier body 2. The water pump 17 is a mechanical device for pumping, lifting, or pressurizing liquids. It consists of an impeller, a pump body, and a drive device. It can pump water from one place to another and can also draw in external water. This is existing technology and will not be described in detail. A water spray plate 18 is fixedly connected to the side wall of the spiral classifier body 2. The water spray plate 18 can flush and clean the reciprocating screw 12 to remove mud from the outside of the reciprocating screw 12. Two water spray plates 19 are fixedly connected to the side wall of the spiral classifier body 2. The two water spray plates 19 can clean the bidirectional screw 5, reduce the impact of mud, and also lubricate the channel, flush the adhesive on the side wall of the spiral classifier body 2, and dilute the excessively dense back sand. The water spray plate 18 and the two water spray plates 19 are all fixedly connected to the water pump 17 through connecting pipes. The bidirectional screw 5, the reciprocating lead screw 12, the pulley assembly 16 and the pulley assembly 23 mentioned above are all made of waterproof and corrosion-resistant materials.
[0015] In this invention, firstly, the operator turns on the control motor 4, causing the output of the control motor 4 to drive the bidirectional screw 5 to rotate via the pulley assembly 6. The rotation of the bidirectional screw 5 causes the two baffles 7 to move outward, thereby enlarging the discharge port and making it easier for the spiral classifier body 2 to discharge materials. This avoids the traditional inability to adjust, making the spiral classifier body 2 more convenient to use. During the adjustment process, the pulley assembly 13 can also drive the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 can drive the sliding rod 14 to slide back and forth via the reciprocating block 15. The sliding rod 14 can drive the cleaning plate 16 to slide back and forth. The movement of the cleaning plate 16 can clean the mud and sand deposited at the discharge port, avoiding excessive mud and sand accumulation, eliminating the need for machine shutdown for cleaning, and eliminating the need for manual cleaning. This increases the processing efficiency of the spiral classifier body 2.
