Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, specifically to a spiral classifier with a slewing bearing mechanism. Background Technology

[0002] Spiral classifiers can mechanically classify minerals by utilizing the principle that solid particles have different specific gravities and therefore settle at different rates in a liquid. During operation, smaller and lighter particles in the minerals float to the surface and flow out through the overflow port with the water flow, while larger and heavier particles settle at the bottom of the tank and are transported by the rotating spiral blades to the return sand port at the top of the tank for discharge, thus achieving the classification effect. However, existing spiral classifiers still have certain defects in their operation.

[0003] A spiral classifier, as proposed in application number CN202221833148.X, relates to the field of mineral processing equipment technology. It includes a tank, an overflow trough, spiral blades, an overflow baffle, and a mixing box. The tank is installed at an incline on a mounting frame. The overflow trough is located at one of the lower ends of the tank. The overflow baffle is slidably connected within the overflow trough. The mixing box is located above the overflow trough. A collection box is connected to the bottom of the overflow trough, and a drain pipe is connected to the bottom of the collection box. A feed inlet is located on one side of the upper wall of the mixing box. A water inlet pipe is connected to the side wall of the mixing box near the feed inlet. A slurry outlet is located on the lower side of the mixing box away from the water inlet pipe. A sand discharge port is located on the lower side of one of the higher ends of the tank. In actual use, this spiral classifier is fixed by the mounting frame, making it inconvenient to adjust the sand discharge angle of the spiral separator according to the sand discharge requirements. Furthermore, a large amount of water is wasted during the spiral classification process, and the water used for classification cannot be recycled, reducing environmental protection benefits.

[0004] Therefore, we propose a spiral classifier with a slewing bearing mechanism to solve the problems mentioned above. Utility Model Content

[0013] The above-mentioned structural design facilitates the control of the engagement of the locking rod with locking grooves at different angles by utilizing the elastic structure of the spring. This facilitates the rotational connection between the support shaft and the connecting plate, and allows for the adjustment and positioning of the angles of the support frame and the chassis.

[0029] Please see Figure 1-5This utility model provides a technical solution: a spiral classifier with a slewing bearing mechanism, including a trough 1, with slewing bearing bodies 2 embedded at both ends of the trough 1, a rotating shaft 3 passing through the middle of the slewing bearing body 2, spiral blades 4 fixedly connected to the outer ring of the rotating shaft 3, a servo motor 5 connected to the rear end of the rotating shaft 3, the servo motor 5 being fixedly connected to the trough 1 via a connecting frame, a sand discharge port 6 installed at the bottom of the rear end of the trough 1, a support frame 7 fixedly installed at the bottom of the trough 1, an angle adjustment structure 8 connected to the middle of the bottom end of the support frame 7, mounting plates 9 installed on both sides of the bottom end of the angle adjustment structure 8, the angle adjustment structure 8 including a connecting plate 801 fixedly installed at the middle of the bottom end of the support frame 7, a support shaft 802 rotatably connected inside the support frame 7, a base plate 803 fixedly connected to the bottom end of the support shaft 802, the two sides of the base plate 803 being fixedly connected to the mounting plates 9, a locking rod 804 slidingly passing through the inside of the connecting plate 801, and upper stops respectively installed on the locking rod 804. The upper retaining ring 805 and the lower retaining ring 806, and the engaging rod 804 between the lower retaining ring 806 and the bottom surface of the chassis 803 are fitted with a spring 807. The engaging rod 804, through the upper retaining ring 805, the lower retaining ring 806, and the spring 807, forms a limiting telescopic structure with the connecting plate 801. The chassis 803 has an engaging groove 808, which is opened at equal angles inside the chassis 803. The engaging groove 808 engages with the bottom end of the engaging rod 804. The design of the above structure allows for the engaging rod to engage with the lower retaining ring 804.

After angle adjustment, the engaging rod 804 can be used to engage with the engaging grooves 808 at different angles for positioning after angle adjustment.

[0030] A collection box 10 is fixedly connected to the front end of the tank 1. A filter mechanism 11 is provided inside the collection box 10. The filter mechanism 11 includes slots 1101 symmetrically opened on both sides of the top of the collection box 10. A seat 1102 is engaged inside the slot 1101. A fixed frame 1103 is fixedly connected to the bottom end of the seat 1102. A filter screen 1104 is fixedly installed at the bottom of the fixed frame 1103. The design of the above structure allows the fixed frame 1103 and the filter screen 1104 to be movably installed inside the collection box 10 through the engagement of the seat 1102 and the slot 1101. This facilitates the filtering of overflowing mineral material and water by the fixed frame 1103 and the filter screen 1104. At the same time, it is convenient to disassemble the fixed frame 1103 and the filter screen 1104 after filtration to realize the discharge of filtered mineral material.

[0032] Working principle: When using a spiral classifier with a slewing bearing mechanism, firstly as follows... Figure 1-5 As shown, according to the requirements of the sand discharge position, the locking rod 804 is pulled to separate it from the current locking groove 808. Then, the tank body 1 and the support frame 7 can rotate at the top of the support shaft 802 via the connecting plate 801 to adjust the angle of the sand discharge port 6. When the adjustment is completed, the lower retaining ring 806 and the locking rod 804 are reset by the spring 807, so that the locking rod 804 can engage with the corresponding locking groove 808 to achieve angle positioning. Then, an appropriate amount of water is continuously injected into the front end of the tank body 1. Then, the ore is put into the front end of the tank body 1. Then, the servo motor 5 is started to drive the rotating shaft 3 and the spiral blade 4 to rotate, so that... When the spiral blade 4 rotates, it can both stir the ore and water to accelerate the stratification and lift the ore deposited at the bottom of the front end of the tank 1 and discharge it through the sand discharge port 6. The upper layer of ore will overflow from the front end of the tank 1 into the collection box 10 with the water flow. At this time, the filter screen 1104 can filter the overflowing ore and water. The filtered water will be stored at the bottom of the collection box 10. Then, the water pump 1201 is started to draw out the water at the bottom of the collection box 10 through the first connecting pipe 1202 and spray it out through the second connecting pipe 1203 and the nozzle seat 1204, so that the water is reinjected into the tank 1 to realize the water recycling.
