[0001] This utility model relates to the field of coal washing, and in particular to a coal washing equipment with wastewater separation function. Background Technology
[0002] Coal washing equipment with wastewater separation function is a device for washing and separating coal lumps, aiming to separate clean coal for easier transportation and use. Most coal washing equipment consists of a conveyor belt, a washing machine, and other moving mechanisms to complete the cleaning of coal lumps.
[0003] The existing equipment involves several steps: first, the coal is placed on a conveyor belt, then it is washed. However, the washing process and direction are too uniform, failing to thoroughly clean all sides of the coal. Finally, the coal is collected. This method results in uneven washing of many sides of coal piled together, requiring repeated washing and wasting manpower and resources. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a coal washing device with wastewater separation function, which aims to improve the problem of inconsistent cleaning of coal blocks of different sizes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal washing device with wastewater separation function, comprising a shell, a water tank fixedly connected to the rear top of the shell, a first feed plate fixedly connected to the top of the water tank, a second slide rail fixedly connected to the front of the water tank, an auger blade slidably connected to the inner wall of the second slide rail, a first motor fixedly connected to the front of the water tank, multiple spray pipes fixedly connected to the top of the shell, multiple spray heads fixedly connected to the bottom of the multiple spray pipes, a second water pipe fixedly connected and penetrating the inner wall of the second slide rail, a water receiving plate fixedly connected to the bottom of the shell, a water pump fixedly connected to the inner wall of the water receiving plate, a first water pipe fixedly connected to the output end of the water pump, a second feed plate fixedly connected to the outer wall of the shell, and a screening assembly provided on the inner wall of the shell.
[0006] Furthermore, the screening assembly includes a fixed block, which is fixedly connected to the inner wall of the outer casing. A second motor is fixedly connected to the outer wall of the fixed block, and a pulley is fixedly connected to the output end of the second motor. One of the pulleys is rotatably connected to the top of the fixed block. Belts are fitted onto the outer walls of multiple pulleys. A rotating block is rotatably connected to the outer wall of one of the pulleys. A screen is rotatably connected inside the rotating block. Multiple first slide rails are provided on both sides of the front end of the outer casing, and multiple sliders are fixedly connected to both sides of the front end of the screen.
[0007] Furthermore, the second water pipe passes through the water tank, the second slide rail, and the spray pipe in sequence and is connected to the spray head.
[0008] Furthermore, the multiple spray heads are evenly arranged on the inner wall of the outer shell, and the multiple spray heads are staggered with the two sides of the screen.
[0009] Furthermore, the plurality of sliders are slidably connected to the outer walls of the plurality of first slide rails.
[0010] Furthermore, the front end of the first feed plate is fixedly connected to the top front end of the second slide rail, and the top of the first water pipe is fixedly connected to the bottom of the water tank.
[0011] Furthermore, the second slide rail is fixedly connected to the outer wall of the housing, the auger blade is movably connected to the top of the housing, and the output end of the first motor is fixedly connected to the rear end of the auger blade.
[0012] Furthermore, a drain outlet is provided on the left rear end of the water receiving plate, and the drain outlet passes through the water receiving plate and the outer shell in sequence.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, coal blocks are placed into the first feed plate, where they fall onto the auger blades. The auger blades are rotated by a first motor, propelling the coal blocks forward. Spray nozzles at the bottom of the spray pipes on the top of the casing spray water onto the coal blocks for initial cleaning. The coal blocks, propelled by the rotating auger blades, also rotate, resulting in more thorough washing. As the auger blades rotate, the coal blocks fall into the second feed plate, where their inclination causes them to fall onto a screen for a second cleaning. The wastewater from this cleaning process falls into a receiving plate, where a pump pumps the filtered water upwards through a second water pipe into a water tank for repeated use. A drain outlet allows for the timely discharge of wastewater.
[0015] 2. In this utility model, the second motor drives one of the pulleys to rotate, and the belt drives the other pulley to rotate together. The movement of the pulleys drives the rotating block to move. The screen fixed to the rotating block will reciprocate back and forth due to the fixation of the first slide rail and the slider. The movement of the screen will cause the coal to continue to move forward. The first layer of screen will screen out coal pieces smaller than normal coal pieces, which will fall into the second layer of screen. The second layer will screen out even smaller pieces, which will fall into the third layer. The second cleaning is carried out on the reciprocating motion of the screen, and the coal will fall into the lower layer layer by layer. Therefore, the stubborn impurities adhering to the coal will be shaken off and cleaned more thoroughly. Each layer is equipped with a spray head for more precise cleaning. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1 , Figure 2 , Figure 3An embodiment of this utility model provides a coal washing device with wastewater separation function, including a shell 1, a water tank 2 fixedly connected to the rear top of the shell 1, a first feed plate 3 fixedly connected to the top of the water tank 2, a second slide rail 14 fixedly connected to the front of the water tank 2, an auger blade 10 slidably connected to the inner wall of the second slide rail 14, a first motor 16 fixedly connected to the front of the water tank 2, multiple spray pipes 4 fixedly connected to the top of the shell 1, multiple spray heads 11 fixedly connected to the bottom of the multiple spray pipes 4, a second water pipe 19 fixedly connected and passing through the inner wall of the second slide rail 14, a water receiving plate 5 fixedly connected to the bottom of the shell 1, a water pump 9 fixedly connected to the inner wall of the water receiving plate 5, a first water pipe 8 fixedly connected to the output end of the water pump 9, a second feed plate 20 fixedly connected to the outer wall of the shell 1, and a screening assembly provided on the inner wall of the shell 1.
[0025] Specifically, coal blocks fall from the first feed plate 3 above the water tank 2 fixed at the top rear of the outer shell 1 into the auger blade 10. The first motor 16 drives the auger blade 10 to move, and at the same time, the spray head 11 installed below the spray pipe 4 sprays water into the auger blade 10 to perform the first round of cleaning on the coal blocks. After passing through the area of the movable and fixed auger blade 10 at the top of the outer shell 1, the coal blocks fall into the second feed plate 20 for the second round of cleaning and sorting. The wastewater after cleaning falls into the water receiving plate 5, and the water pump 9 behind the water receiving plate 5 outputs water to the first water pipe 8, so that the water after screening the coal blocks can be reused and waste is avoided.
[0026] Reference Figure 4 The screening assembly includes a fixed block 12, which is fixedly connected to the inner wall of the outer casing 1. A second motor 18 is fixedly connected to the outer wall of the fixed block 12. A pulley 17 is fixedly connected to the output end of the second motor 18. One of the pulleys 17 is rotatably connected to the top of the fixed block 12. A belt 22 is fitted on the outer wall of the multiple pulleys 17. A rotating block 7 is rotatably connected to the outer wall of one of the pulleys 17. A screen 15 is rotatably connected inside the rotating block 7. Multiple first slide rails 21 are opened on both sides of the front end of the outer casing 1. Multiple sliders 6 are fixedly connected to both sides of the front end of the screen 15.
[0027] Specifically, the second motor 18 drives the pulley 17 to rotate. The two pulleys 17 are connected by a belt 20, so that the two pulleys 17 rotate simultaneously. The rotation of the pulleys 17 drives the rotating block 7, which in turn drives the screen 15 to move. The slider 6 moves along the inner wall of the first slide rail 21, and the screen 15 also moves within this range. Due to the movement of the rotating block 7, the screen 15 will reciprocate. The movement of the screen 15 will sort the coal pieces that fall to the top of the screen 15. The first layer of screen 15 will screen out smaller coal pieces that fall to the second layer, and the second layer will screen out even smaller coal pieces that fall to the third layer of screen 15. All the coal pieces will be concentrated and packaged through the opening on the front side of the outer casing 1 due to the movement of the screen 15.
[0028] Reference Figure 5 The second water pipe 19 passes through the water tank 2, the second slide rail 14, and the spray pipe 4 in sequence and is connected to the spray head 11.
[0029] Specifically, the second water pipe 19 supplies water to the spray heads 11 installed at the bottom of multiple spray pipes 4 through the water tank 2 for the first round of cleaning of coal blocks.
[0030] Reference Figure 2 Multiple spray heads 11 are evenly arranged on the inner wall of the outer shell 1, and the multiple spray heads 11 are staggered with the two sides of the screen 15.
[0031] Specifically, the spray head 11 can spray water to clean the coal blocks more comprehensively on the outer wall of the outer shell 1, and the staggered arrangement with the screen 15 is to ensure that the coal blocks on each layer of screen 15 can be thoroughly and comprehensively cleaned.
[0032] Reference Figure 4 Multiple sliders 6 are slidably connected to the outer walls of multiple first slide rails 21.
[0033] Specifically, the multiple sliders 6 that are slidably connected within the multiple first slide rails 21 can prevent the screen 15 from moving left and right, so that the coal blocks fall into the water receiving plate 5.
[0034] Reference Figure 2 The front end of the first feed plate 3 is fixedly connected to the top front end of the second slide rail 14, and the top of the first water pipe 8 is fixedly connected to the bottom of the water tank 2.
[0035] Specifically, the first feed plate 3 allows coal lumps and the water from the first round of washing to fall into the screen 15, and the washed water will re-enter the water tank 2 through the first water pipe 8.
[0036] Reference Figure 5 The second slide rail 14 is fixedly connected to the outer wall of the housing 1, the auger blade 10 is movably connected to the top of the housing 1, and the output end of the first motor 16 is fixedly connected to the rear end of the auger blade 10.
[0037] Specifically, the first motor 16 outputs power to the auger blade 10 on the inner wall of the second slide rail 14, and the auger blade 10 pushes the coal block on the outer shell 1.
[0038] Reference Figure 2 A drain outlet 13 is provided on the left side of the rear end of the water receiving plate 5, and the drain outlet 13 passes through the water receiving plate 5 and the outer shell 1 in sequence.
[0039] Specifically, the water used to wash the coal blocks multiple times needs to be replaced in a timely manner, and drain outlet 13 serves to replace the wastewater.
[0040] Working principle: When coal washing is required, the coal block conveyor belt is first placed on the first feed plate 3. Due to the tilting effect of the first feed plate 3, the coal block will fall to the top of the outer shell 1. At this time, the auger blade 10 starts to move and continues to move forward. Under the movement of the auger blade 10, the coal block on the outer shell 1 will keep turning. The spray pipe 4 at the top of the outer shell 1 continuously sprays water onto the turning coal block with the spray head 11 to clean it.
[0041] Coal chunks fall into the second feed plate 20 at the end of the auger blade 10. Due to the inclination of the second feed plate 20, the coal chunks fall onto the screen 15. The output of the second motor 18 drives the pulley 17. The two pulleys 17, driven by the belt 22, cause the rotating block 7 to move, which in turn drives the screen 15 to move back and forth. The screen 15 is connected to the outer casing 1 by a slider 6. The movement of the screen 15 causes the coal chunks to shake and turn. Multiple spray nozzles 11 fixed on both sides of the outer casing 1 continuously spray cleaning liquid onto the coal chunks. Smaller coal chunks are screened out by the first layer of screen 15 and then screened out by the second layer, and even smaller coal chunks are screened out by the third layer of screen 15. There are openings on the front of the outer casing 1 to facilitate the collection of cleaned coal chunks of different sizes by the staff.
[0042] The wastewater after washing the coal will fall into the water receiving plate 5. The water pump 9 at the rear end of the water receiving plate 5 and the first water pipe 8 will continuously pump water into the water tank 2. The water tank 2 will continue to supply water to the spray head 11 from the second water pipe 19. The water can be discharged and replaced from the drain outlet 13.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
