Description

Technical Field

[0001] The utility model relates to the technical field of mine sand and gravel aggregate processing, in particular to an intelligent water flushing device for wet production of a circular vibrating screen for mines. Background Art

[0002] In the sand and gravel aggregate processing operation, since some boulders have a large content of soil and mud, the phenomenon of blocking the material outlet of the equipment often occurs, thus affecting the processing efficiency of the equipment. Therefore, in order to improve the processing efficiency of the equipment and the quality of the finished aggregate, it is often necessary to add a water flushing device to the vibrating screen to clean the surface soil covering.

[0003] At present, in the aggregate processing system, a device for directly flushing with a water pipe is mostly used. Generally, the mud content percentage of the same batch of materials remains in a certain range. However, due to the difference in the feeding amount, the thickness of the materials and the overall mud content will be different, and it is necessary to manually adjust the water flushing amount and the density arrangement of the water pipes. This treatment method has the problems of low work efficiency, affecting the production progress, and wasting water resources. For this reason, we propose an intelligent water flushing device for wet production of a circular vibrating screen for mines to solve the above-mentioned problems. Summary of the Utility Model

A circular vibrating screen body 3 is fixedly connected between the telescopic ends of the spring adapter blocks 2, and sand and gravel aggregates enter the circular vibrating screen body 3 for cleaning. Two groups of vertical plates 5 are fixedly connected to one side wall of the inner cavity of the outer box 1. A deflector 6 is fixedly connected to the tops of the two groups of vertical plates 5. A sleeve frame 7 spanning the top is fixedly connected to the side wall of the deflector 6. A thickness sensor 8 is fixedly connected to the inner wall of the sleeve frame 7. A drain pipe 11 is fixedly connected to the bottom of the side wall of the outer box 1 away from the vertical plate 5. Two groups of fixed blocks 12 are fixedly connected to the outside of the side wall of the outer box 1 where the spring adapter blocks 2 are provided. Between the two groups of fixed blocks 12, a rotatably connected screw 13 and two fixed slide bars 16 are provided, and the two groups of slide bars 16 are located above and below the screw 13. A motor 14 with an output end connected to the screw 13 in a transfer manner is fixedly connected to the side wall of the fixed block 12 close to the drain pipe 11. A slide block 15 is threadedly slidably connected to the outer wall of the screw 13, and the two groups of slide bars 16 penetrate through the slide block 15. By driving the screw 13 to rotate through the motor 14, the slide block 15 threadedly connected to the screw 13 translates along the slide bars 16. A water tank 21 is fixedly connected to the top of the slide block 15. A water pump 20 is provided on the top of the water tank 21. A moving arm 17 located above the circular vibrating screen body 3 is fixedly connected to the side wall of the water tank 21. A high-pressure nozzle 18 is provided at the bottom of the moving arm 17. A water supply pipe 19 located above the moving arm 17 is provided at the top output end of the water pump 20, and the water supply pipe 19 is communicated with the high-pressure nozzle 18. A control terminal 22 is provided on the outer side wall of the outer box 1, and the thickness sensor 8, the motor 14, and the water pump 20 are all electrically connected to the control terminal 22.

[0032] A support block 24 is sleeved on the outer wall of the water supply pipe 19, and the bottom of the support block 24 is connected to the moving arm 17. By providing the support block 24 on the top of the moving arm 17, the stability of the water supply pipe 19 during use can be effectively improved.

[0033] On both sides of the top of the deflector 6, there are limit plates 23. During the process of importing sand and gravel aggregates, the limit plates 23 can effectively reduce the splashing of sand and gravel aggregates to both sides of the deflector 6.

[0039] Specific working principle:

[0040] When this solution is in operation, sand and gravel aggregates are imported into the circular vibrating screen body 3 from the deflector 6. After the sand and gravel aggregates are imported into the circular vibrating screen body 3 from the deflector 6, the thickness sensor 8 sends the thickness type signal of the sand and gravel aggregates to the control terminal 22 to obtain the thickness of the sand and gravel aggregates in the circular vibrating screen body 3. Since the bottom area of the circular vibrating screen body 3 is certain, the mud content can be obtained by combining the percentage of mud in the sand and gravel aggregates, so as to control the water spray amount of the water pump 20 through the high-pressure nozzle 18, so as to effectively utilize water resources while fully cleaning. The specific water spray amount can be obtained through experiments with the specific bottom area of the circular vibrating screen body 3 as a constant, the arrangement form of the high-pressure nozzles 18 as a fixed quantity, and the thickness and the percentage of mud content as variables. During the cleaning process, the circular vibrating screen body 3 vibrates by itself. The control terminal 22 turns on the motor 14 to drive the screw 13 to rotate and drive the moving arm 17 to move back and forth. The sand and gravel aggregates are fully washed in the circular vibrating screen body 3. The spring adapter block 2 can absorb the impact of the self-vibration of the circular vibrating screen body 3, and also endows the self-vibration of the circular vibrating screen body 3 with a certain up and down movement ability, accelerating the discharge of muddy water from the seepage holes 301, reducing the labor input of workers at the same time, and improving the cleaning efficiency of sand and gravel aggregates.

[0041] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
