Description

Technical Field

[0001] This utility model belongs to the technical field of coal washing and beneficiation equipment, and specifically relates to a coal washing and beneficiation equipment with adjustable washing direction. Background Technology

[0002] Coal washing and beneficiation equipment is used to process raw coal. Its main function is to separate impurities (such as gangue, sulfides, etc.) from the coal through physical or chemical methods, thereby improving the quality and cleanliness of the coal. Existing coal washing and beneficiation equipment often uses nozzles with a fixed direction for the initial washing and screening of coal. However, before washing, the surface of the coal contains highly adhesive impurities. Fixed nozzles can only wash the coal surface from a single direction, which is not conducive to the targeted removal of highly adhesive impurities. This reduces the coal washing and impurity removal efficiency of the equipment and affects the production quality of the coal. Therefore, a new structure is proposed to solve the above problems.

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.

[0028] Please see Figures 1-3 As the first embodiment of this utility model: a coal washing and beneficiation device with adjustable flushing direction, including: a direction adjustment component 210 and a transmission component 300. The direction adjustment component 210 is installed inside the washing and beneficiation tank 200, and a fixing frame 100 is provided on the outside of the washing and beneficiation tank 200. The transmission component 300 is installed on the front of the fixing frame 100.

[0029] The transmission assembly 300 includes a drive pulley 310 that drives three sets of driven pulleys 320 to rotate. The curved surface of the drive pulley 310 has a belt groove 311, and the curved surface of the driven pulleys 320 has a belt groove 321. A transmission belt 330 is sleeved between the belt groove 311 and the belt groove 321.

[0030] A discharge port 201 is provided on the left side of the washing tank 200. A sliding door is installed on the left side of the discharge port 201. Three sets of directional adjustment components 210 are installed from left to right on the upper inner side of the washing tank 200.

[0031] The direction adjustment component 210 has a cylindrical structure, and several sets of nozzles 211 are installed sequentially from front to back at the bottom of the direction adjustment component 210.

[0032] The top of several sets of nozzles 211 are connected to the water inlet pipe inside the direction adjustment component 210, and the rear side of the water inlet pipe is connected to the external pressurized water tank.

[0033] The transmission assembly 300 also includes a transmission box, which has an L-shaped structure. A drive pulley 310 is installed on the lower right side inside the transmission box, and a driven pulley 320 is installed directly above the drive pulley 310.

[0034] Both belt groove 311 and belt groove 321 have several sets of teeth on their inner sides, and the transmission belt 330 has several sets of teeth of the same specifications as teeth 1 that mesh with each other on its inner side.

[0035] Two sets of identical driven pulleys 320 are installed at equal intervals on the left side of the driven pulley 320. The rear side of each set of driven pulleys 320 is connected to the connecting shaft on the front side of its respective rear direction adjusting component 210.

[0036] A stepper motor is installed on the lower right side of the transmission box. The output end of the stepper motor is connected to the docking shaft on the front side of the drive pulley 310 via a coupling.

[0037] A belt groove 322 is provided on the rear side of the driven pulley 320, and a transmission belt 340 is sleeved on the outer side of the belt groove 322 of the left driven pulley 320 and the right driven pulley 320.

[0038] The inner side of the belt groove 321 is provided with several sets of teeth 3, and the inner side of the transmission belt 340 is provided with several sets of teeth 4 that are the same as the teeth 3 and mesh with each other.

[0039] Coal is conveyed from the upper conveyor belt to the washing tank 200. At this time, the sliding door on the left side of the washing tank 200 is closed, the three sets of directional adjustment components 210 are stationary, and water is supplied through the water inlet pipe. Several sets of nozzles 211 spray pressurized water onto the surface of the coal for washing. Then, the stepper motor (stepper motors are existing technology, and their models can be selected according to available models on the market, which will not be described here) can be started. The stepper motor drives the drive pulley 310 to rotate like a pendulum, which drives the driven pulley 320 directly above the drive pulley 310 through the transmission belt 330. The driven pulley 320 at the top moves through the drive pulley 330. The pulley 320 drives the two sets of driven pulleys 320 on its left side to move simultaneously. It should be noted that among the three sets of driven pulleys 320, the belt groove 322 on the rear side of the middle driven pulley 320 is slightly larger than the belt groove 322 on the rear side of the two left and right driven pulleys 320. The purpose of this design is to allow the transmission belt 240 to better transmit power to the middle driven pulley 320. Therefore, the three sets of direction adjusting components 210 move in a pendulum motion synchronously under the drive of the three sets of driven pulleys 320, thereby driving several sets of nozzles 211 to move in a pendulum motion, spraying coal at multiple angles, which significantly improves the efficiency of coal washing.

[0041] The lower inner surface of the washing tank 200 is a sloping structure with a gradually increasing slope from left to right, and the inclination angle of the lower inner surface of the washing tank 200 is 10 degrees.

[0042] A collection trough is provided below the washing tank 200. Several sets of drainage holes are opened between the top of the collection trough and the bottom of the washing tank 200. A drain pipe is connected to the bottom left side of the inner side of the collection trough. Example 2: Please refer to Figure 1 Based on the above embodiments, a control box 110 is provided on the right side inside the fixed frame 100, and a vibration motor is provided above the control box 110. The bottom of the vibration motor is fixed to the bottom of the washing tank 200.

[0043] After the coal washing is completed, the wastewater inside the washing tank 200 will flow down through several sets of drainage holes into the collection tank, and then flow to the left through the inclined lower surface of the inner side of the collection tank into the drain pipe for discharge. At the same time, the vibration motor can be started to vibrate the bottom right side of the washing tank 200, so that the washed coal can move to the left along the inner lower surface of the washing tank 200 and finally enter the next process through the discharge port 201. Therefore, the final effect is to achieve automatic coal discharge through vibration, which greatly improves the discharge efficiency.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
