Description

Technical Field

[0001] This application relates to the field of water discharge device technology, and in particular to a negative pressure buffer integrated slag discharge device for a vertical shaft slag chute. Background Technology

[0002] Gas drainage is a task that almost all coal mines must carry out. During the gas drainage process, it is necessary to drill holes, and the water, slag, and gas in the holes will flow into the drainage pipeline together. Therefore, it is necessary to install an integrated slag discharge device in the gas drainage pipeline to discharge the slag-water mixture in the pipeline, thereby ensuring the normal operation of the gas drainage work.

[0003] During the use of existing integrated slag discharge devices, the gas-water-slag mixture entering the water discharger body will impact the surface of the float, damaging the surface of the float. At the same time, the gas entering the water discharger body will carry dust particles upward, reducing the gas separation effect. Summary of the Invention

[0004] To address the issues that the gas-water-slag mixture entering the chute body impacts the surface of the float, and that the gas entering the chute body carries dust particles upwards, this application provides a negative pressure buffer integrated slag discharge device for vertical shaft slag outlets.

[0005] This application provides a negative pressure buffer integrated slag discharge device for a vertical shaft slag chute, which adopts the following technical solution: A negative pressure buffer integrated slag discharge device for a vertical shaft slag chute includes a water discharger body. A reversing valve is fixedly installed inside the water discharger body. An air input pipe, a gas outlet pipe, and a gas filter element are provided on the reversing valve. A connecting rod is provided at the bottom of the reversing valve, and a float is provided at the bottom of the connecting rod. An air-water-slag inlet is provided on the side wall of the water discharger body. A water-slag discharge outlet is provided at the bottom of the water discharger body. A cover plate is snapped onto the top of the water discharger body.

[0006] The water dispenser body has a filter cartridge inside, and a rotating ring is rotatably fitted on the outer wall of the filter cartridge. Two scrapers are fixedly connected to the rotating ring. Both scrapers are in contact with the outer wall of the water dispenser body. Several stirring rods are provided on both scrapers. A conical tooth is fixedly connected between the two scrapers.

[0007] A motor is fixedly installed on the outer wall of the water dispenser body. A central shaft is fixedly connected to the output end of the motor. The central shaft passes through the inner wall of the water dispenser body. A main bevel tooth is fixedly connected to the end of the central shaft. The main bevel tooth is located inside the water dispenser body. The main bevel tooth and the secondary bevel tooth mesh with each other. The main bevel tooth is located above the secondary bevel tooth.

[0008] By adopting the above technical solution, the driven conical teeth that mesh with the main conical teeth are driven to rotate along the outer wall of the filter cylinder by a scraper and several stirring rods fixedly connected to the bottom of the conical teeth. The rotating scraper can scrape off the slag mixture accumulated on the outer wall of the filter cylinder, and the several rotating stirring rods can evenly stir the incoming slag mixture, which can quickly break the gas in the slag mixture and improve the gas separation efficiency.

[0009] Optionally, the bottom and top of the filter cartridge are open, and several inclined rods are fixedly connected to the bottom of the filter cartridge, with the bottom ends of the inclined rods fixedly connected to the bottom of the water dispenser body.

[0010] By adopting the above technical solution, several diagonal supports are connected to the bottom of the water dispenser body and the bottom of the filter cartridge, which supports the filter cartridge. The opening design at the top and bottom of the filter cartridge facilitates the sinking of liquid passing through the filter cartridge and the upward escape of gas passing through the filter cartridge.

[0011] Optionally, a limit ring is fixedly connected to the inner wall of the rotating ring.

[0012] The outer wall of the filter cartridge is provided with an annular limiting groove, and the limiting ring and the annular limiting groove are rotatably engaged.

[0013] By adopting the above technical solution, the rotational fit between the annular limiting groove on the outer wall of the filter cartridge and the limiting ring fixedly connected to the inner wall of the rotating ring prevents the structure on the rotating ring from deflecting.

[0014] Optionally, an annular baffle is fixedly connected to the inner wall of the water dispenser body, and the end of the annular baffle is inclined downward.

[0015] By adopting the above technical solution, the annular baffle fixedly connected to the inner wall of the water dispenser body reduces the amount of dust particles flying into the water dispenser body and reduces the problem of dust particles mixing with gas and being discharged outward.

[0016] Optionally, the gas-water-slag inlet end is located outside the water discharger body, and the gas-water-slag inlet is connected to the output end of the external gas extraction pipeline.

[0017] The end of the air input pipe is located outside the body of the water dispenser, and the air input pipe is connected to the outside air.

[0018] The gas outlet pipe is located inside the water discharge device body, and a gas pump is connected to one end of the gas outlet pipe.

[0019] The gas filter element is located inside the water dispenser body.

[0020] By adopting the above technical solution, the air input pipe and the gas outlet pipe allow the gas entering the body of the water discharger from the gas-water-slag inlet to pass through the gas filter element and then be discharged from the gas outlet pipe.

[0021] Optionally, a water sludge discharge port is provided at the bottom of the water discharge device body, and a discharge filter box is connected to the bottom of the water sludge discharge port.

[0022] By adopting the above technical solution, the discharge filter box can filter the slag material discharged from the slag discharge port.

[0023] Optionally, the side wall of the discharge filter box is provided with a slag discharge port.

[0024] By adopting the above technical solution, solid slag is selected and separated using the slag discharge port.

[0025] Optionally, a filter plate is hinged to the bottom of the slag discharge port, and the filter plate is inclined.

[0026] By adopting the above technical solution and using an inclined filter plate, it is convenient for solid slag to roll out of the slag discharge port along the filter plate.

[0027] Optionally, a plurality of ear plates are fixedly connected to the inner wall of the discharge filter box, and the plurality of ear plates are all located below the filter plate, and an elastic spring is fixedly connected between the plurality of ear plates and the bottom of the filter plate.

[0028] By adopting the above technical solution, elastic springs fixedly connected between several ear plates and the bottom of the filter plate generate an impact force on the filter plate when slag mixture is discharged from the filter plate. This causes the filter plate to be subjected to a downward force, which drives the filter plate to rotate along the hinge end. The elastic springs fixedly connected between several ear plates and the bottom of the filter plate are all compressed. Under the compressed state of the elastic springs, an upward force is provided to the filter plate, causing the filter plate to shake continuously. This improves the separation efficiency of solid and liquid slag and reduces the accumulation of slag on the filter plate.

[0029] Optionally, the bottom of the discharge filter box is provided with a liquid discharge port.

[0030] After being filtered and separated by the discharge filter box, the liquid residue is discharged along the liquid discharge port.

[0031] In summary, this application includes at least one of the following beneficial technical effects of a negative pressure buffer integrated slag discharge device for a vertical shaft slag chute: In this application, the filter cartridge fixedly installed inside the water discharger body causes the slag mixture entering the water discharger body through the gas-water-slag inlet to be impacted and blocked, avoiding the slag mixture from impacting the float inside the water discharger body and reducing damage to the surface material of the float. The hole design on the filter cartridge ensures that the liquid and gas in the slag mixture entering the water discharger body can directly pass through the filter cartridge, improving the separation effect of gas.

[0032] In this application, the scraper is designed to rotate to remove the slag mixture accumulated on the outer wall of the filter cartridge. The rotating design of several stirring rods can evenly stir the incoming slag mixture and quickly break up the gas in the slag mixture, thereby improving the gas separation efficiency.

[0033] In this application, the setting of the annular baffle reduces the amount of dust particles flying into the body of the water discharger, and reduces the problem of dust particles mixing with gas and being discharged outward. Attached Figure Description

[0037] This application discloses a negative pressure buffer integrated slag discharge device for a vertical shaft slag chute.

[0044] Reference Figure 6 The filter cartridge 12 has an annular limiting groove 122 on its outer wall, and the limiting ring 134 and the annular limiting groove 122 are rotatably engaged.

[0045] Reference Figure 5 An annular baffle 18 is fixedly connected to the inner wall of the water dispenser body 1, and the end of the annular baffle 18 is inclined downward.

[0046] Reference Figure 4 The gas-water-slag inlet 11 is located outside the water discharger body 1, and the gas-water-slag inlet 11 is connected to the output end of the external gas extraction pipeline.

[0047] Reference Figure 4 The end of the air inlet pipe 21 is located outside the water outlet body 1, and the air inlet pipe 21 is connected to the outside air.

[0048] Reference Figure 4 The gas outlet pipe 22 is located inside the water discharger body 1, and a gas pump is connected to one end of the gas outlet pipe 22.

[0049] Reference Figure 4 The gas filter element 23 is located inside the water dispenser body 1.

[0050] The implementation principle of Example 1 is as follows: The operating principle of the water discharger body 1 in this application is as follows: The cover plate 16 is locked and snapped onto the top of the water discharger body 1. The reversing valve 2, which is set inside the water discharger body 1, drives the connecting rod 24 to move up or down according to the position of the float 25. The gas-water-slag inlet 11 is connected to the output end of the external gas extraction pipeline, the air input pipeline 21 is connected to the external air, and a gas pump is connected to one end of the gas outlet pipeline 22. The gas filter element 23 is set inside the water discharger body 1. When the gas pump is started, the gas inside the water discharger body 1 is extracted from the water discharger body 1 by passing through the gas filter element 23, the reversing valve 2, and the gas outlet pipeline 22 in sequence. When the gas inside the water dispenser body 1 is evacuated, the inside of the water dispenser body 1 is under negative pressure. At this time, the gas-water-slag inlet 11 can be opened, and a mixture of coal slag, water, gas, and other waste materials can be added into the water dispenser body 1 through the gas-water-slag inlet 11. The mixture of coal slag and other waste materials entering the water dispenser body 1 begins to separate into layers due to gravity. The liquid, coal slag, and other waste materials sink, while the gas rises. Finally, the upper part of the water dispenser body 1 is filled with gas, and the lower part is filled with waste materials. At this time, the connecting rod 24 fixedly connected to the float 25 is located in the lower part of the water dispenser body 1 under its own weight, so that the air input pipe 21 in the reversing valve 2... When the gas outlet pipe 22 is closed and the reversing valve 2 is open, there is a cavity inside the cavity. One side of the cavity is the gas filter element 23, and the other side is the air inlet pipe 21 and the gas outlet pipe 22. The air inlet pipe 21 is located below the gas outlet pipe 22. At this time, external air cannot enter the interior of the drain body 1 along the air inlet pipe 21. The gas inside the drain body 1 is continuously drawn out by the gas pump. In this way, a certain force is always applied upward through the water slag discharge port 17 outside the drain body 1. Due to the negative pressure balance inside the drain body 1, the slag mixture at the bottom of the drain body 1 will not flow out from the water slag discharge port 17 and will always be located at the bottom of the drain body 1.

[0051] The gas in the upper part of the water discharger body 1 passes through the gas filter element 23 located inside the water discharger body 1, enters the reversing valve 2, and is finally drawn out of the water discharger body 1 by the gas pump along the gas outlet pipe 22, and then transported to the gas treatment equipment. With the buoyancy generated by the slag mixture in the lower part of the water discharger body 1, the float 25 and the connecting rod 24 fixedly connected to the float 25 rise, so that the air input pipe 21 in the reversing valve 2 opens and the gas outlet pipe 22 closes. At this time, the outside air enters the water discharger body 1 along the air input pipe 21. The outside gas entering the water discharger body 1 restores the air pressure inside the water discharger body 1 to normal, and the mixture in the lower part of the water discharger body 1 is discharged along the water slag discharge port 17.

[0052] The filter cylinder 12, which is fixedly installed inside the water discharger body 1, causes the slag mixture entering the water discharger body 1 through the gas-water-slag inlet 11 to be impacted and blocked, thus avoiding the slag mixture from impacting the float 25 inside the water discharger body 1 and reducing damage to the surface material of the float 25. The hole design on the filter cylinder 12 can ensure that the liquid and gas in the slag mixture entering the water discharger body 1 can directly pass through the filter cylinder 12, thereby improving the separation effect of gas.

[0053] By starting the motor 14 fixedly installed on the outer wall of the water discharger body 1, the motor 14 is a geared asynchronous motor, which causes the central shaft 141 fixedly connected to the output end of the motor 14 to rotate, driving the main bevel gear 142 fixedly connected to the end of the central shaft 141 to rotate. When the main bevel gear 142 rotates, it drives the secondary bevel gear 133 that meshes with the main bevel gear 142, and then drives the scraper 131 and several stirring rods 132 fixedly connected to the bottom of the secondary bevel gear 133 to rotate along the outer wall of the filter cylinder 12. The rotating scraper 131 can scrape off the slag mixture accumulated on the outer wall of the filter cylinder 12, and the several rotating stirring rods 132 can evenly stir the incoming slag mixture, quickly breaking the gas in the slag mixture, and improving the gas separation efficiency.

[0054] Several diagonal rods 121 are connected to the bottom of the water dispenser body 1 and the bottom of the filter cartridge 12, which support the filter cartridge 12. The opening design at the top and bottom of the filter cartridge 12 facilitates the sinking of liquid passing through the filter cartridge 12 and the upward escape of gas passing through the filter cartridge 12.

[0055] The rotational engagement between the annular limiting groove 122 on the outer wall of the filter cartridge 12 and the limiting ring 134 fixedly connected to the inner wall of the rotating ring 13 prevents the structure on the rotating ring 13 from deflecting.

[0056] The annular baffle 18, which is fixedly connected to the inner wall of the water dispenser body 1, reduces the amount of dust particles flying into the interior of the water dispenser body 1 and reduces the problem of dust particles being mixed with gas and discharged outward.

[0057] Example 2:

[0058] Reference Figure 1 and Figure 3 A discharge filter box 15 is connected to the bottom of the water slag discharge outlet 17.

[0059] Reference Figure 3 The side wall of the discharge filter box 15 is provided with a slag discharge port 151.

[0060] Reference Figure 3 The bottom of the slag discharge port 151 is hinged to a filter plate 152, which is inclined.

[0061] Reference Figure 8The inner wall of the discharge filter box 15 is fixedly connected with several ear plates 153, which are all located below the filter plate 152. Elastic springs 154 are fixedly connected between the ear plates 153 and the bottom of the filter plate 152.

[0062] Reference Figure 7 The bottom of the discharge filter box 15 is provided with a liquid discharge port 155.

[0063] The implementation principle of Example 2 is as follows: by adopting the above technical solution, the air input pipe 21 and the gas outlet pipe 22 allow the gas entering the interior of the water discharger body 1 from the gas-water-slag inlet 11 to pass through the gas filter element 23 and then be discharged from the gas outlet pipe 22.

[0064] The discharge filter box 15 is designed to filter the slag discharged from the slag discharge port 17; the slag discharge port 151 is designed to select and separate solid slag; in addition, the inclined filter plate 152 facilitates the solid slag to roll out of the slag discharge port 151 along the filter plate 152.

[0065] The elastic springs 154, which are fixedly connected between several ear plates 153 and the bottom of the filter plate 152, generate an impact force on the filter plate 152 when the slag mixture is discharged from it. This causes the filter plate 152 to be subjected to a downward force, which drives the filter plate 152 to rotate along the hinge end. The elastic springs 154, which are fixedly connected between several ear plates 153 and the bottom of the filter plate 152, are all compressed. Under the compressed state, the elastic springs 154 provide an upward force to the filter plate 152, causing the filter plate 152 to shake continuously. This improves the separation efficiency of solid and liquid slag and reduces the accumulation of slag on the filter plate 152.

[0066] After being filtered and separated by the discharge filter box 15, the liquid residue is discharged along the liquid discharge port 155.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
