Description

Technical Field

[0001] This utility model relates to the field of coal chemical technology, and more specifically, to a particle classification and separation device for coal chemical wastewater. Background Technology

[0002] Coal chemical industry refers to the process of using coal as raw material and chemically processing it into gaseous, liquid, and solid fuels and chemicals. In order to make more thorough use of coal resources, it is necessary to recover the coal powder and coal lumps from the wastewater that contains them.

[0003] A search revealed a utility model patent with publication number CN220802247U, which discloses a particle grading and separation device for coal chemical wastewater. The device includes a main assembly comprising a separation box, a transmission motor, a drive motor, a conveying hose, an mounting ring, a connecting rod, a mounting base, a lifting base, two guide rods, a lead screw, a rotating shaft, an eccentric wheel, and three filter plates. The mounting ring is fixedly connected to the bottom of the outer wall of the conveying hose. The patent uses a drive motor to drive the lead screw, which in turn drives the lifting base, which in turn drives the connecting rod, which in turn drives the conveying hose. When the lifting base moves up and down, the connecting rod causes the conveying hose to swing back and forth, preventing the wastewater from having a fixed contact position with the top filter plate. The transmission motor drives the rotating shaft, which in turn drives the eccentric wheel, causing the eccentric wheel to vibrate the filter plates. This vibration separates coal lumps and coal powder from the filter plates, preventing coal lumps and powder from clogging the filter holes and improving separation efficiency.

[0004] However, the aforementioned patents have the following shortcomings: the filtered coal powder particles contain moisture, and there is a certain degree of adhesion between the coal powder particles and the filter plate. Vibration of the filter plate alone is insufficient for discharging the particles, and it is also inconvenient to adjust the filter plate used for particle grading, as well as to adjust the outer diameter of the particles used for grading. Therefore, we propose a particle grading and separation device for coal chemical wastewater. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a particle classification and separation device for coal chemical wastewater.

[0026] Based on Embodiment 1, as shown in Figures 1 to 6, a second screw hole 18 is provided on the front of the separation box 1 and below the second slot 4. A second fixing seat 19 is fixedly connected to the end of the collection box 5. A second fixing hole 20 is provided on the second fixing seat 19.

[0027] Based on Embodiments 1 and 2, as shown in Figures 1 to 4, the water injection mechanism 2 includes a Z-shaped tube 23 rotatably connected to the top of the separation tank 1 via bearings and a first reduction motor 22 fixedly installed on the top surface of the separation tank 1. The bottom end of the Z-shaped tube 23 extends into the inner cavity of the separation tank 1, and a rotary joint 25 is fixedly installed at the top end of the Z-shaped tube 23. A water guide pipe 26 is fixedly connected to the top end of the rotary joint 25. A first gear 24 is fixedly sleeved on the output shaft of the first reduction motor 22, and a second gear 29 is fixedly sleeved on the side of the top end of the Z-shaped tube 23. The second gear 29 and the first gear 24 mesh with each other. A drain hopper 27 is provided at the bottom of the separation tank 1 to discharge the filtered wastewater. A control panel 28 is fixedly installed on the side of the separation tank 1. The control panel 28 is electrically connected to the second reduction motor 12 and the first reduction motor 22, respectively. The control panel 28 is used to control the second reduction motor 12 and the first reduction motor 22. Control is performed by using the power supply of an external device to control the control panel 28, the second geared motor 12, and the first geared motor 22; this is existing technology.

[0028] It should be noted that this utility model is a particle grading and separation device for coal chemical wastewater. In use, firstly, the first reduction motor 22 is started to drive the first gear 24 to rotate. The meshing transmission between the first gear 24 and the second gear 29 drives the Z-shaped tube 23 to rotate. Simultaneously, the wastewater is guided into the inner cavity of the separation tank 1 via the water guide pipe 26, rotary joint 25, and Z-shaped tube 23, causing the wastewater to fall onto the filter screen 7 at the top of the inner cavity of the separation tank 1. Then, the wastewater is filtered step-by-step through multiple filter screens 7, thereby separating the coal chemical particles. The filtered wastewater is discharged from the drain hopper 27. Next, multiple second reduction motors 12 are started to drive multiple reciprocating screws 10 to rotate. The screw transmission between the reciprocating screws 10 and the transmission plate 11 drives the transmission plate 11 and scraper 13 to move laterally back and forth. The scraper 13 uses the multiple filter screens 7... The particles filtered down are scraped into the inner cavity of the collection box 5 and collected, ensuring the filtration effect of the filter screen 7. Finally, rotating the second butterfly screw 21 can release the fixing of the collection box 5, thereby removing the collection box 5 to process the collected particles. In addition, removing the first butterfly screw 17 releases the fixing of the filter screen 7, thereby cleaning the particles trapped in the filter holes of the filter screen 7. At the same time, the filter screen 7 can be replaced, so that filter screens with different pore sizes can be selected to classify and separate wastewater particles.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
