Description

Technical Field

[0001] This utility model relates to the technical field of ore cleaning, and in particular to a circular vibrating screen. Background Technology

[0002] After the ore is mined, it needs to be processed. The main processing steps are crushing and further processing. After crushing, the surface of the ore will be mixed with a lot of dust, so the crushed ore needs to be washed.

[0003] For example, patent application number CN202321621607.2 discloses an ore raw material washing device. In this patent, the water pump 4 operates while the motor 32 in the washing mechanism 3 is turned. Then, the ore raw material is put into the feeding port. The ore raw material rotates with the rotating spiral blades 34. The high-pressure nozzles 36 in the spraying component 35 achieve all-round washing of the ore raw material. The washed ore raw material is discharged centrally through the discharge port. The wastewater from washing the ore raw material flows out of the working cylinder 31 through the sewage outlet. After passing through the fine screen 23, the mesh plate 22 and the dust collection filter cloth, the waste and mud in the wastewater are filtered. The filtered wastewater enters the water tank 1 and is then transported to the washing mechanism 3 by the water pump 4 and the water guide pipe 5 to wash the ore raw material. This realizes the recycling of water resources and increases the energy-saving effect of the washing equipment.

[0004] In the existing technology, during the use of this equipment, because the shape of the crushed ore is not fixed, the ore moves under the push of the spiral blades, and the ore often gets stuck between the spiral blades and the working cylinder, causing equipment damage. At the same time, the conveying method of the spiral blades is not very effective in cleaning the ore, and the ore and dust will flow together, resulting in poor cleaning effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a circular vibrating screen to solve the problem of poor cleaning effect of the ore washing equipment in the prior art described in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circular vibrating screen, comprising...

[0007] A vibration frame containing a vibrator;

[0008] Several columns are connected to the bottom of the vibration frame via damping springs, and the vibration frame is set at an angle;

[0009] The filter screen is installed inside the vibrating frame;

[0010] Several vibrating screens are respectively set inside the vibrating frame and distributed in a stepped manner, with adjacent screens being fixedly connected by a butt mesh;

[0011] Several first water pipes are rotatably installed inside the vibrating frame, and each first water pipe has several first nozzles.

[0012] Preferably, the docking mesh has a number of longitudinally arranged baffles.

[0013] Preferably, a gearbox is fixedly connected to the side wall of the vibration frame, the gearbox has a reducer for driving the gearbox, the reducer has a servo motor for driving the reducer, and the output end of the gearbox is connected to the rotating shaft of the first water pipe.

[0014] Preferably, the vibrating frame has a second water pipe with a plurality of second nozzles that extend into the gap between the filter screen and the bottom of the vibrating frame.

[0015] Preferably, a first discharge plate is fixedly connected to the end of the vibrating mesh.

[0016] Preferably, a second discharge plate is fixedly connected to the end of the filter screen.

[0017] The beneficial effects of adopting the above technical solutions are:

[0018] This application uses a vibrator to drive a vibrating frame to vibrate, which in turn drives a vibrating screen and a filter screen to vibrate. This causes the ore to vibrate on the vibrating screen and the connecting screen. At the same time, the first water pipe rotates back and forth, which allows the first nozzle to spray water onto the surface of the ore to wash it. Ore that does not meet the particle size requirements will fall onto the filter screen, allowing some mud and sand to pass through the filter screen and be washed away by the second nozzle.

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 In this first embodiment, a circular vibrating screen includes...

[0025] The vibration frame 30 has a vibrator 31 inside;

[0026] Several columns 10 are connected to the bottom of the vibration frame 30 via damping springs 20, and the vibration frame 30 is set at an angle.

[0027] Filter screen 50 is installed inside the vibrating frame 30;

[0028] Several vibrating screens 40 are respectively set in the vibrating frame 30 and distributed in a stepped manner. Two adjacent screens 50 are fixedly connected by a connecting screen 41.

[0029] Several first water pipes 61 are rotatably mounted inside the vibrating frame 30, and each first water pipe 61 has several first nozzles 60.

[0030] This embodiment is implemented as follows:

[0031] When in use, the vibrator 31 drives the vibrating frame 30 to vibrate, so that the ore poured into the feed end 32 can flow along the vibrating net 40, which can filter the ore, so that the ore with small particle size falls onto the filter screen 50. The filter screen 50 can filter the ore with small particle size. At the same time, the first water pipe 61 rotates back and forth, so that the first nozzle 60 on the first water pipe 61 can spray on the ore to achieve the washing of the ore.

[0032] The advantage of this application over the prior art is that it can screen the ore and filter out the mud and sand.

[0033] Please see Figure 2 , 3 The connecting net 41 has several longitudinally arranged baffles 42.

[0034] The baffle 42 can guide the ore, allowing it to be separated and more dispersed.

[0035] Please see Figure 1 , 3 A gearbox 62 is fixedly connected to the side wall of the vibration frame 30. The gearbox 62 has a reducer 63 that drives the gearbox 62. The reducer 63 has a servo motor 64 that drives the reducer 63. The output end of the gearbox 62 is connected to the shaft of the first water pipe 61.

[0036] The servo motor 64 drives the reducer 63, the reducer 63 drives the gearbox 62, and the gearbox 62 drives the shaft of the first water pipe 61 to rotate.

[0037] Please see Figure 1 , 2 The vibrating frame 30 has a second water pipe 70, and the second water pipe 70 has a plurality of second nozzles 71, which extend into the gap between the filter screen 50 and the bottom of the vibrating frame 30.

[0038] The second nozzle 71 on the second water pipe 70 can be used to wash away the mud and sand filtered by the filter screen 50.

[0039] Please see Figure 2 The first discharge plate 43 is fixedly connected to the vibrating net 40 at the end.

[0040] The ore on the vibrating net 40 is guided out by the first discharge plate 43.

[0041] Please see Figure 2 The end of the filter screen 50 is fixedly connected to a second discharge plate 51.

[0042] The ore on the filter screen 50 is guided out through the second discharge plate 51.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
