Description

Technical Field

[0001] This utility model relates to the field of coal gangue processing technology, and in particular to a washing device for coal gangue processing. Background Technology

[0002] Coal gangue washing is used to remove impurities and useless components from coal gangue. Washing is usually carried out in a washing tank.

[0003] Typically, a drainage component and a circulation component connected to the drainage component are installed in the immersion tank. The circulation component allows a specific liquid to be discharged along the drainage component and circulate within the immersion tank, thereby completing the washing and rinsing of the coal gangue. However, in actual use, the coal gangue is usually placed directly into the immersion tank. Before processing, operators need to use large equipment to feed the material before immersion. After immersion, the liquid needs to be drained and then all the coal gangue is removed from the immersion tank. Only after the immersion tank is completely emptied can the next immersion operation be carried out.

[0004] This method significantly extends the total processing time, meaning that after the previous batch of coal gangue has been cleaned, the next batch of coal gangue can only be processed after the washing tank has been emptied. Furthermore, the process requires on-site material feeding, which further increases the processing time. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a washing device for coal gangue processing, which solves the problem that the preparation process of the washing tank before and after processing coal gangue increases the overall processing time.

[0006] The technical solution of this utility model is as follows: a washing device for coal gangue processing, including a washing tank with an open top, the open end of the washing tank being covered with a sealing cover, a plurality of drain pipes being provided at the bottom of the inner side of the washing tank, a pressurizing chamber being provided at the top of the sealing cover, the pressurizing chamber being connected to a liquid delivery pipe through a flange, a plurality of diversion pipes being provided on the surface of the pressurizing chamber, a pressure opening valve being provided inside the diversion pipe, a connecting component being provided at the end of the diversion pipe, the bottom of the connecting component being snapped into the drain pipe to connect the drain pipe and the diversion pipe, and a circulation component being provided on one side of the inner wall of the washing tank.

[0007] Furthermore, the pressurizing chamber is butterfly-shaped with an internal cavity. The diversion pipes connected to the pressurizing chamber are evenly arranged on both sides of the pressurizing chamber. The pressure opening valve in each diversion pipe is located on the side close to the pressurizing chamber, ensuring that the liquid in the pressurizing chamber can be blocked by the pressure opening valve to generate pressure.

[0008] Furthermore, the connecting component includes a flange bolted to the surface of the closed cover and connected to the diversion pipe. The surface of the closed cover has a through hole adapted to the flange. A double-layer rubber sleeve is provided at the bottom of the closed cover and concentric with the through hole. A thickened layer is provided at the bottom end of the double-layer sleeve. The drain pipe is interference-fitted with the double-layer sleeve and snapped into the interior of the connecting component.

[0009] Furthermore, the drain pipe is a hollow columnar structure with several through grooves evenly spaced on both sides of its surface. The number of through grooves on the side of the drain pipe facing the circulation component is greater than that on the opposite side, so that the liquid discharged from the drain pipe has a greater flow rate in a specific direction.

[0010] Furthermore, the circulation assembly includes a guardrail mesh installed on the side wall of the immersion tank. A connecting pipe is installed at the bottom of the side wall of the immersion tank covered by the guardrail mesh. The connecting pipe is connected to an external separator and a circulation pump through a flange and finally communicates with the pressurization chamber. The circulation assembly is connected to external separators and other components through a flange for easy assembly and disassembly. The guardrail mesh can also block coal gangue to a certain extent to prevent it from clogging the connecting pipe.

[0011] Furthermore, the edge of the sealing cover is provided with a downward bending portion, which is sleeved on the outside of the immersion tank. The length of the bending portion is greater than the length of the double-layer sleeve of the connecting component, so that the sealing cover can be positioned by the bending portion when it is close to the immersion tank.

[0012] Furthermore, the sidewall of the opening end of the immersion tank is evenly provided with several lugs, and the bent part of the closing cover contacts the lugs.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the operator can simultaneously put coal gangue into multiple immersion tanks in advance, and then cover the corresponding immersion tank with a sealing cover as needed. Several components set on the top of the sealing cover transport the liquid to the drain pipe, and the liquid enters the immersion tank through the through groove on the surface of the drain pipe to immerse the coal gangue. After the immersion operation in one immersion tank is completed, the sealing cover only needs to be removed and placed on top of another sealing cover to continue the immersion. At this time, the operator can drain and remove the coal gangue in the immersion tank that has been immersed, so that the whole operation can be carried out in a state of uninterrupted immersion process.

[0015] 2. In this invention, when liquid is continuously injected into the pressurizing chamber, the liquid cannot directly enter the diversion pipe through the pressure opening valve. Therefore, it will continue to accumulate in the pressurizing chamber until the pressure is sufficient to pass through the pressure opening valve. After the liquid passes through the pressure opening valve, the pressure in the pressurizing chamber decreases and cannot continuously support the liquid to pass through the pressure opening valve. Therefore, the process of the liquid entering the drain pipe through the diversion pipe along the pressurizing chamber is intermittent, ensuring that the liquid discharged from the drain pipe has a certain pressure each time. At the same time, the intermittent flushing of the coal gangue can also ensure that the impurities on the surface of the coal gangue have enough time to sink or float, avoiding the problem that the impurities cannot leave the area under impact due to continuous flushing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, as Figure 1-4 As shown, a washing device for processing coal gangue includes a washing tank 1 with an open top, a sealing cover 3 covering the open end of the washing tank 1, and several lugs 2 evenly arranged on the side wall of the open end of the washing tank 1. The bent part of the sealing cover 3 contacts the lugs 2.

[0023] Several drain pipes 4 are provided at the bottom of the inner side of the immersion tank 1, and a pressurizing chamber 5 is provided at the top of the sealing cover 3. The pressurizing chamber 5 is connected to the infusion pipe through a flange. Several diversion pipes 6 are provided on the surface of the pressurizing chamber 5. The pressurizing chamber 5 is butterfly-shaped with an internal cavity. The diversion pipes 6 connected to the pressurizing chamber 5 are evenly arranged on both sides of the pressurizing chamber 5. The pressure opening valve in each diversion pipe 6 is located on the side close to the pressurizing chamber 5 to ensure that the liquid in the pressurizing chamber 5 can be blocked by the pressure opening valve to generate pressure. A pressure opening valve is provided in the diversion pipe 6.

[0024] The end of the diversion pipe 6 is provided with a connecting component 7. The connecting component 7 includes a flange bolted to the surface of the sealing cover 3 and connected to the diversion pipe 6. The surface of the sealing cover 3 is provided with a through hole adapted to the flange. The bottom of the sealing cover 3 is provided with a rubber double-layer sleeve concentric with the through hole. The bottom end of the double-layer sleeve is provided with a thickened layer. The drain pipe 4 is interlocked with the double-layer sleeve and inserted into the interior of the connecting component 7. The edge of the sealing cover 3 is provided with a downward bending part. The bending part is sleeved on the outside of the immersion tank 1. The length of the bending part is greater than the length of the double-layer sleeve of the connecting component 7, so that when the sealing cover 3 is close to the immersion tank 1, the placement of the sealing cover 3 can be positioned by the bending part. The bottom of the connecting component 7 is connected to the drain pipe 4 and the diversion pipe 6.

[0025] A circulation component 8 is installed on one side of the inner wall of the immersion tank 1. The drain pipe 4 is a hollow columnar structure with several through grooves evenly spaced on both sides of its surface. The number of through grooves on the side of the drain pipe 4 facing the circulation component 8 is greater than that on the opposite side, so that the liquid discharged from the drain pipe 4 has a larger flow rate in a specific direction. The circulation component 8 includes a guardrail net installed on the side wall of the immersion tank 1. A connecting pipe is installed at the bottom of the side wall of the immersion tank 1 covered by the guardrail net. The connecting pipe is connected to an external separator and a circulation pump through a flange and finally connected to the pressurization chamber 5. The circulation component 8 is connected to external separators and other components through a flange for easy assembly and disassembly. The guardrail net can also block coal gangue to a certain extent to prevent coal gangue from clogging the connecting pipe.

[0026] The working principle of this utility model is as follows: First, when using it, the operator can fill several immersion tanks 1 with coal gangue. Then, according to the needs, the corresponding immersion tank 1 is covered with a sealing cover 3. During the covering process, the folded edge at the bottom of the sealing cover 3 first contacts the top of the immersion tank 1. The operator only needs to ensure that the folded edge wraps around the immersion tank 1 to complete the positioning of the sealing cover 3 and the immersion tank 1.

[0027] At the same time, the connecting component 7 inside the sealed cover 3 is aligned with the drain pipe 4 to complete the snap-fit. At this time, the drain pipe 4 is connected to the pressurizing chamber 5 through the connecting component 7 and the diversion pipe 6. The operator can inject liquid into the pressurizing chamber 5. The liquid in the pressurizing chamber 5 cannot enter the diversion pipe 6 through the pressure start valve, causing the internal pressure to gradually increase until the pressure exceeds the set value of the pressure start valve. At this time, the liquid in the pressurizing chamber 5 passes through the diversion pipe 6 and the connecting component 7 into the drain pipe 4. The liquid in the washing tank 1 is flushed through the through groove of the drain pipe 4. During the continuous process, the liquid in the washing tank 1 gradually fills up. The operator can open the circulation component 8 to draw out the liquid in the washing tank 1 to prevent the liquid from overflowing.

[0028] After completing the immersion operation in the current immersion tank 1, the operator can disconnect the circulation component 8 from the external equipment and remove the sealing cover 3 and place it on top of another immersion tank 1 to continue the immersion operation. At this time, the operator can take out the coal gangue in the immersion tank 1 that has been immersed.

[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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
