Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

First embodiment:

As shown in Figures 1-4, a mining solid waste screening device includes a screening box 1, and a crushing wheel 2 is arranged at the upper end of the screening box 1. The crushing wheel 2 is driven to rotate by a first motor 21, and the screening A screen frame 3 is arranged at the lower end of the box 1, a screen 31 is arranged on the screen frame 3, a feeding port 11 is arranged on the top of the screening box 1, and one side of the screening box 1 is connected with the screen frame 3. The discharge port 12, the bottom of the screening box 1 is provided with a sewage outlet 13, the outer side of the screening box 1 is provided with a water tank 4, a filter screen 41 is fixed longitudinally in the water tank 4, and the top of the water tank 4 is fixed on both sides of the filter screen 41 A conduit 42 is provided, the free end of the conduit 42 on one side extends into the upper end of the screen frame 3 in the screening box 1, the free end of the conduit 42 on the other side is connected and fixed with the sewage outlet 13, and the conduit 42 extends into the screening box 1 A water mist nozzle 43 is fixed at one end, and a water pump 44 is provided at the connection between the water tank 4 and the conduit 42 corresponding to the water mist nozzle 43 .

Preferably, the screening box 1 is supported and fixed by a support rod 14 .

Preferably, a baffle 15 is set in the feeding port 11, and the middle part of the baffle 15 is connected with the rotating shaft of the feeding port 11. When crushing, the self-balancing property of the baffle 15 is used to avoid waste fragments at the feeding port 11. splashes and dust flying.

Preferably, the screen frame 3 is inclined and arranged to facilitate discharging.

Second embodiment:

Further, one end of the screen frame 3 is hinged with the screening box 1, and the other end extends out of the screening box 1. A spring 32 is fixed at the connection between the extension end of the screen frame 3 and the screening box 1, and the hinge of the screen frame 3 is The end is lower than the protruding end of the screen frame 3, and the discharge port 12 is arranged on the side of the hinged end of the screen frame 3. The elastic force of the spring 32 causes the crushed waste blocks to fall on the screen frame 3. When the screen mesh frame 3 is vibrated elastically due to its gravity, the screening efficiency of the screen mesh on it is improved.

Further, a second motor 33 is fixedly arranged on the screen box 1 corresponding to the projecting end of the screen frame 3, and the output end of the second motor 33 is connected to a cam 34.

The waste is poured from the feeding port 11, and the baffle 15 in the feeding port 11 can use its self-balancing performance to cover the feeding port 11 under normal conditions, so as to avoid small fragments after crushing when the crushing wheel 2 is crushed. The splash of the block will cause accidental injury of personnel, and at the same time, the flying of dust on the upper end of the feeding port 11 is also avoided.

After being crushed by the crushing wheel 2, the waste falls onto the screen 31 on the screen frame 3, and is screened and filtered. At the same time, the second motor 33 can be driven to control the rotation of the cam 34, so that it reciprocates and pushes the screen frame 3 to generate reciprocating vibration under the action of the spring 31, thereby improving the screening efficiency of the screen 31. , can also facilitate the discharge. While the material is being screened, the water in the water tank 4 can be pumped by the water pump 44 and transported through the conduit 42, and sprayed onto the screen 31 through the water mist nozzle 43, so that the slag, dust, etc. generated by the waste in the screening box 1 can be screened Adhering to the water mist, after screening, it is discharged through the sewage outlet 13 and introduced into the water tank 4, and the filter screen 41 arranged in the water tank 4 can realize the partition of waste in the water tank. Therefore, the recycling of water is convenient, and the cleaning of waste residue after screening is also convenient.

The above-mentioned embodiments merely describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Under the premise of not departing from the design concept of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope of the present invention, and the technology claimed by the present invention shall be protected. The content has been fully described in the claims.
