Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a vibrating cleaning device for coal mine processing screens. Background Technology

[0002] Currently, in coal processing, it is necessary to separate impurities such as coal gangue in the coal mine. Wet coal washing is often used, which separates coal by creating stratification in water due to different densities. Screens are used in this process, but they are prone to caking on the surface during use, which makes the separation incomplete and reduces the efficiency of coal washing. Therefore, the screens need to be replaced and cleaned regularly.

[0003] The current cleaning method usually involves staff manually rinsing the surfaces with a hose and a handgun. This manual rinsing method increases the workload for the staff, and the splashing water can easily soak their clothes.

[0004] Therefore, it is necessary to provide a new type of vibration cleaning equipment for coal mine processing screens to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a vibration cleaning device for coal mine processing screens.

[0006] The coal mine processing screen vibration cleaning equipment provided by this utility model includes: a cleaning box, the inside of which is provided with a cleaning component that is movably connected, and both sides inside the cleaning box are provided with a support frame for fixing the screen.

[0007] The cleaning assembly includes a cleaning frame, with adapter brackets on both sides of the cleaning frame. A guide rod is inserted into the interior of one adapter bracket, and a reciprocating screw is threaded into the interior of the other adapter bracket. Both the guide rod and the reciprocating screw are mounted on the outer wall of the cleaning box.

[0008] The cleaning frame has an upper cleaning strip at its inner top and a lower cleaning strip at its inner bottom. A connecting pipe is installed inside the cleaning frame. The connecting pipe has an arched structure, and several connecting nozzles are installed on its inner top and inner sidewalls.

[0009] Preferably, the cleaning frame has a plurality of slidingly connected pins inside, the pins are T-shaped, the bottom end of the pins is arc-shaped, and a spring is provided between the pins and the cleaning frame.

[0010] Preferably, the bottom end of the spring is fixedly connected to the top of the cleaning frame, the top end of the spring is fixedly connected to the top end of the ejector pin, and the bottom end of the ejector pin extends into the interior of the cleaning frame.

[0011] Preferably, the cleaning frame has several evenly distributed through holes inside, and the inner wall of the through holes abuts against and is slidably connected to the outer wall of the ejector pin.

[0012] Preferably, a mounting bracket is provided on one side wall of the cleaning frame, a pump body is provided inside the mounting bracket, the output end of the pump body is provided with a connecting pipe, and both sides of the connecting pipe are provided with connecting hoses.

[0013] Preferably, the end of the connecting hose away from the adapter pipe is provided with a communicating water guide pipe, and the end of the water guide pipe away from the connecting hose is in communication with the interior of the communicating pipe.

[0014] Preferably, cylinders and telescopic rods are provided on both sides inside the cleaning frame, and the ends of the cylinders and telescopic rods on the same side are fixedly connected to the outer wall of the corresponding support frame.

[0016] Compared with related technologies, the coal mine processing screen vibration cleaning equipment provided by this utility model has the following beneficial effects:

[0017] 1. This utility model, through the setting of the cleaning component, can drive the cleaning frame to move back and forth by rotating the reciprocating screw in the cleaning component during use. At this time, the cleaning components in the cleaning frame can automatically clean the screen without the need for manual operation by the staff. This not only reduces the fatigue of the staff, but also reduces the phenomenon of water splashing randomly and causing the staff's clothes to get wet by the cover of the cleaning box.

[0018] 2. By setting up a movable ejector pin, when the cleaning frame slides back and forth, the force applied by the spring to the ejector pin can move the ejector pin into the screen holes, thereby squeezing and cleaning the coal particles stuck in the screen holes, thus improving the cleaning effect of the device in the later stage.

[0019] 3. This utility model, through the bidirectional distribution of the upper and lower cleaning strips, allows the upper and lower cleaning strips to rub and vibrate against the screen when the cleaning frame moves, thus completing the double-sided cleaning of the screen in one go.

[0027] To make the objectives, technical solutions, and advantages of this 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 6 The present invention provides a vibrating cleaning device for coal mine processing screens. The vibrating cleaning device for coal mine processing screens includes a cleaning box 1, a cleaning component 2 that is movably connected inside the cleaning box 1, and a support frame 3 for fixing the screen on both sides inside the cleaning box 1.

[0030] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The cleaning assembly 2 includes a cleaning frame 21, with adapter brackets 214 on both sides of the cleaning frame 21. A guide rod 25 is inserted into the interior of one adapter bracket 214, and a reciprocating screw 23 is threaded into the interior of the other adapter bracket 214. Both the guide rod 25 and the reciprocating screw 23 are mounted on the outer wall of the cleaning box 1. An upper cleaning strip 211 is provided at the top inner side of the cleaning frame 21, and a lower cleaning strip 212 is provided at the bottom inner side of the cleaning frame 21. A connecting pipe 24 is installed inside the cleaning frame 21. The connecting pipe 24 has an arched structure, and its top inner side and inner wall are... Each component is equipped with several interconnected nozzles 241. Inside the cleaning frame 21, there are several slidingly connected ejector pins 22. The ejector pins 22 have a T-shaped structure and an arc-shaped bottom end. A spring 221 is installed between the ejector pins 22 and the cleaning frame 21. The bottom end of the spring 221 is fixedly connected to the top of the cleaning frame 21, and the top end of the spring 221 is fixedly connected to the top end of the ejector pin 22. The bottom end of the ejector pin 22 extends into the interior of the cleaning frame 21. Inside the cleaning frame 21, there are several evenly distributed through holes 213. The inner wall of the through holes 213 abuts against and is slidably connected to the outer wall of the ejector pin 22.

[0031] It should be noted that during use, when the water pump is working and delivers external water into the connecting pipe 24 until the water is sprayed outward from the nozzle 241 on the connecting pipe 24, the rotating reciprocating screw 23 can drive the adapter bracket 214 to move through the threaded structure. The moving adapter bracket 214 can drive the cleaning frame 21 to move back and forth on the outer wall of the guide rod 25. At this time, the upper cleaning strip 211 and the lower cleaning strip 212 located inside the cleaning frame 21 can simultaneously brush and clean both sides of the screen through the friction and vibration force when the screen comes into contact with each other.

[0032] Since the cleaning component 2 is located inside the cleaning tank 1, and the nozzles 241 are distributed horizontally and vertically downward, the cleaning tank 1 can block the water splashing during the water spraying process, reducing the random splashing of water and preventing the staff's clothes from getting wet. Therefore, the user experience of this device can be improved.

[0033] When the cleaning frame 21 slides back and forth, the force applied to the ejector pin 22 by the spring 221 can move the ejector pin 22 into the screen hole in the screen, thereby squeezing and cleaning the coal particles stuck in the screen hole, thus improving the cleaning effect of the device in the later stage.

[0034] Furthermore, during the movement of the cleaning frame 21, since the end of the ejector pin 22 is an arc-shaped structure, when the end of the ejector pin 22 abuts against the outer wall of the screen or the side wall of the screen hole, the arc-shaped structure can transform the horizontal movement force of the ejector pin 22 into a vertical driving force, thereby causing the ejector pin 22 to move upward and separate from the outer wall of the screen or the inner wall of the screen hole, thus enabling the cleaning frame 21 to move stably.

[0035] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 A mounting bracket 4 is provided on one side wall of the cleaning frame 21. A pump body 41 is provided inside the mounting bracket 4. The output end of the pump body 41 is provided with a connecting pipe 42. Both sides of the connecting pipe 42 are provided with connecting hoses 43. The end of the connecting hose 43 away from the connecting pipe 42 is provided with a connecting water pipe 242. The end of the water pipe 242 away from the connecting hose 43 is connected to the inside of the connecting pipe 24.

[0036] It should be noted that: with the pump body 41 in operation, external water can be delivered to the cleaning assembly 2 and sprayed outward through the nozzle 241 to clean the screen. With the connection hose 43 in operation, when the reciprocating screw 23 moves the cleaning frame 21, the connection hose 43 can move synchronously with the cleaning frame 21, thus avoiding obstruction to the movement of the cleaning frame 21 and making the subsequent movement of the cleaning frame 21 smoother.

[0037] In the embodiments of this utility model, please refer to Figure 1 and Figure 6 The cleaning frame 21 has cylinders 31 and telescopic rods 32 on both sides inside. The ends of cylinders 31 and telescopic rods 32 on the same side are fixedly connected to the outer wall of the corresponding support frame 3.

[0038] It should be noted that: by setting up the cylinder 31, the working cylinder 31 can drive the support frame 3 to move, thereby making the inner wall of the support frame 3 abut against the outer wall of the screen, fixing the screen in the washing box 1. When the cylinder 31 moves in extension and retraction, the telescopic rod 32 can move in extension and retraction synchronously with the support frame 3, thereby improving the vertical support strength of the cylinder 31 in the later stage, thus improving the stability of the support frame 3 in supporting the screen.

[0039] In the embodiments of this utility model, please refer to Figure 1 and Figure 6 The top of the cleaning tank 1 is equipped with a controller 12, and the inside of the cleaning tank 1 is equipped with a drain pipe 11, and the drain pipe 11 is equipped with a valve.

[0040] It should be noted that: by setting the controller 12, when the controller 12 is connected to the electrical components in this device, it is convenient for staff to operate and use this device;

[0041] Meanwhile, the cleaning tank 1 can also collect the water after cleaning, making it convenient for staff to centrally treat the wastewater after cleaning.

[0042] The working principle of the coal mine processing screen vibration cleaning equipment provided by this utility model is as follows:

[0043] When using this cleaning equipment, the operator can first place the screen to be cleaned in the support frame 3 and control the cylinder 31 to extend until the inner walls of the two support frames 3 on both sides abut against the two sides of the screen, thus fixing the screen. Then the pump body 41 can be controlled to deliver water.

[0044] At this time, the water source can flow into the water guide pipe 242 and the connecting pipe 24 in the cleaning assembly 2 through the connecting hose 43 until the water source is sprayed outward from the nozzle 241 on the connecting pipe 24. At this time, the operation of the motor at the end of the reciprocating screw 23 can drive the reciprocating screw 23 to rotate. The rotating reciprocating screw 23 can drive the adapter bracket 214 to move through the thread structure. At this time, the adapter bracket 214 can drive the cleaning frame 21 to reciprocate on the outer wall of the guide rod 25.

[0045] During the movement of the cleaning frame 21, the upper cleaning strip 211 and the lower cleaning strip 212 located inside the cleaning frame 21 can simultaneously brush and clean the top and bottom of the screen by friction and vibration when they come into contact with the top and bottom of the screen.

[0046] Furthermore, during the movement of the cleaning frame 21, since the end of the ejector pin 22 is an arc-shaped structure, when the end of the ejector pin 22 abuts against the outer wall of the screen or the side wall of the screen hole, the arc-shaped structure can transform the horizontal movement force of the ejector pin 22 into a vertical driving force, thereby enabling the ejector pin 22 to move upward and separate from the outer wall of the screen or the inner wall of the screen hole, thus allowing the cleaning frame 21 to move stably.

[0047] When the ejector pin 22 moves to the position opposite to the screen hole, the ejector pin 22 can move under the force of the spring 221. At this time, the downward moving ejector pin 22 can be inserted into the screen hole, thereby ejecting and cleaning the coal particles embedded in the screen hole, thus improving the cleaning effect of the device on the screen.

[0048] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0049] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
