Description

Technical Field

[0001] The utility model relates to the field of gas extraction, in particular to a novel extraction device. Background Art

[0002] When the amount of gas gushing out of coal mines is large and difficult to dilute and remove by ventilation, extraction equipment can be used to collect and manage the gas to reduce the ventilation burden. Similarly, gas is a toxic gas and is easily ignited, so it needs to be extracted to eliminate dangerous factors. Gas can also be used as fuel after processing.

[0003] During the gas extraction process, water and coal ash in the coal seam will accumulate in the gas extraction pipeline. If not handled in time, the extraction pipeline will be blocked, greatly affecting the extraction efficiency. Existing gas extraction devices with filtering devices usually need to be equipped with multiple electronic components for internal filtering control, which is complex to manufacture and costly. The existing technology usually only discharges sewage and filtered residues, and cannot replace and clean the filter well. After long-term use, the filtering effect will be greatly affected.

[0004] Therefore, those skilled in the art provide a novel extraction device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a new type of extraction device is proposed. The device can perform solid-liquid separation treatment on sewage and impurities such as coal ash in the gas extraction pipe, realize automatic discharge of sewage while ensuring the air tightness of gas extraction, and centrally treat solid impurities such as coal ash. The internal filter plate can be disassembled and cleaned, which improves the cleaning of the pipeline and the filter device during the extraction process, prevents internal blockage and improves the gas extraction efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel extraction device, comprising an extraction device body, wherein convex plates are fixedly arranged at the upper part of the inner part of the extraction device body, and a plurality of the convex plates are penetrated with telescopic bodies at the upper and lower ends, and a plurality of telescopic bodies are penetrated with telescopic rods slidably arranged at the lower ends, and a plurality of the upper ends of the telescopic rods are connected with springs, and a plurality of the upper ends of the springs are connected to the inner side of the upper end of the telescopic body, and a plurality of the lower ends of the telescopic rods are fixedly arranged with load-bearing plates, and a short positioning block is threadedly connected with a bolt on one side of the inner side of the front and rear ends of the load-bearing plate, and a long positioning block is threadedly connected with a bolt on the other side of the inner side of the front and rear ends of the load-bearing plate, and a No. 1 filter plate is fixedly arranged at the lower ends of the two long positioning blocks, and a secondary sewage outlet is opened at one side of the inner part of the load-bearing plate, and a No. 2 filter plate is fixedly arranged at the other side of the secondary sewage outlet;

[0007] A gas extraction pipe is fixedly arranged at one side of the upper end of the extraction device body, a gas extraction pipe is fixedly arranged at the other side of the upper end of the extraction device body, a No. 3 filter plate is fixedly arranged at the bottom end of the gas extraction pipe, a plurality of activated carbon adsorption plates are penetrated inside the No. 3 filter plate, a concentration tester is fixedly arranged at the upper inner side of the rear end of the extraction device body, a sensor is arranged at the upper end of the bottom plate of the extraction device body, a movable plate is clamped at the lower front end of the extraction device body, and a plurality of No. 1 bolts are threadedly penetrated on the movable plate;

[0008] Through the above technical solution, when the accumulated sewage and coal ash on the load-bearing plate reaches a certain weight, the load-bearing plate will drive the telescopic rod to move downward, and the spring will be stretched during the movement process. When the weight reaches a certain level, the secondary sewage outlet and the main sewage outlet opening will be aligned to discharge the sewage. After the sewage is discharged, the weight becomes lighter, and multiple springs rebound to move the load-bearing plate up. When too much coal ash accumulates, it will cause the load-bearing plate to move down to the contact sensor to issue an alarm to remind you to close the extraction channel. Subsequently, multiple No. 1 bolts can be removed to remove the movable plate, and the long positioning block and the short positioning block can be disassembled from the inside to take out the No. 1 filter plate to replace or clean it.

[0009] Furthermore, the multiple springs have a large elastic force and can be stretched to a long distance. After being stretched to a long distance, the multiple springs can still slowly rebound and reset, and the load-bearing plate is light in weight;

[0010] Through the above technical solution, the load-bearing plate can change its height according to the mass of the sewage and coal ash it receives, and can rise again after the sewage is discharged.

[0011] Furthermore, the lower ends of the two short positioning blocks and the long positioning block are fixedly arranged on the upper end of the first filter plate;

[0012] Through the above technical solution, the No. 1 filter plate can be better fixed obliquely on the load-bearing plate, and the filter plate can be disassembled by removing the bolts on the short positioning block and the long positioning block.

[0013] Furthermore, the opening size of the secondary sewage outlet is smaller than the opening size of the primary sewage outlet;

[0014] Through the above technical solution, the secondary sewage outlet can better discharge sewage when it moves down to the position of the main sewage outlet along with the load-bearing plate.

[0015] Furthermore, the first filter plate is placed at an angle, and a space is provided between the first filter plate and the load-bearing plate;

[0016] Through the above technical solution, the liquid-solid separation and removal of sewage coal ash can be better achieved, and subsequent treatment and utilization can be carried out more effectively.

[0017] Furthermore, the area on one side of the load-bearing plate fits with the interior of one side of the extraction device body, and the area on the other side of the load-bearing plate fits with the interior of the other side of the extraction device body;

[0018] Through the above technical solution, while ensuring good airtightness inside the main body of the extraction device, it is difficult for sewage to leak from the load-bearing plate and the inner wall of the main body of the extraction device.

[0019] Furthermore, the sensor will only send out an alarm when it contacts the load-bearing plate;

[0020] Through the above technical solution, the sensor can better receive the information that the load-bearing plate is overloaded, so as to remind the cleaning of the coal ash and the No. 1 filter plate.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a new type of extraction device, which can classify, filter and remove sewage and coal ash flowing into the gas extraction pipe, so as to better realize liquid-solid classification treatment. When sewage reaches a certain level, it can be automatically discharged without destroying the airtightness of the internal extracted gas. When there are a lot of coal ash and other substances accumulated inside, an alarm message can be issued to remind the staff to clean the internal environment, which further improves the cleanliness of the extraction pipeline, prevents it from being blocked by foreign matter, and improves the gas extraction efficiency.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-7 The utility model provides an embodiment: a novel extraction device, including an extraction device body 1. In order to better fix the telescopic body 16, convex plates 11 are fixedly arranged at the upper part of the inner part of the extraction device body 1. The upper and lower ends of the plurality of convex plates 11 are penetrated with the telescopic body 16. The lower ends of the plurality of telescopic bodies 16 are penetrated with telescopic rods 9 that are slidably arranged. The upper ends of the plurality of telescopic rods 9 are connected with springs 19. The upper ends of the plurality of springs 19 are connected to the inner side of the upper end of the telescopic body 16. The lower ends of the plurality of telescopic rods 9 are fixed with a load-bearing plate 2. When there is no debris such as sewage on the load-bearing plate 2, the telescopic rods 9 will not cause a large pulling force on the springs 19. Extend, in order to facilitate the oblique direction to fix and removably place the No. 1 filter plate 4, a short positioning block 3 is connected to the inner side of the front and rear ends of the load-bearing plate 2 by a bolt thread on one side, and a long positioning block 6 is connected to the inner side of the front and rear ends of the load-bearing plate 2 by a bolt thread on the other side, and the lower ends of the two long positioning blocks 6 are fixedly provided with a No. 1 filter plate 4, and the No. 1 filter plate 4 can be disassembled, cleaned or replaced by removing the bolts later, and a secondary sewage outlet 14 is opened at one side of the inside of the load-bearing plate 2, and a No. 2 filter plate 8 is fixedly provided at the other side of the secondary sewage outlet 14, and the No. 2 filter plate 8 can further prevent the coal ash from being discharged together with the sewage, so as to better realize the liquid-solid separation treatment;

[0035] A gas extraction pipe 13 is fixedly arranged at one side of the upper end of the extraction device body 1. One side of the gas extraction pipe 13 is connected to the extraction pipeline and extends to the deep coal seam. A gas extraction pipe 10 is fixedly arranged at the other side of the upper end of the extraction device body 1. The other side of the gas extraction pipe 10 is connected to the gas extraction pump to extract the gas. A No. 3 filter plate 15 is fixedly arranged at the bottom of the gas extraction pipe 10. A plurality of activated carbon adsorption plates 20 are arranged inside the No. 3 filter plate 15 to further filter and purify the extracted gas. A concentration tester 12 is fixedly arranged at the upper inner side of the rear end of the main body 1 to detect the internal gas extraction concentration in real time. A sensor 5 is arranged at the upper end of the bottom plate of the extraction device main body 1. When the load-bearing plate 2 carries too many impurities, the contact sensor 5 sends out an alarm to remind cleaning. A movable plate 18 is clamped at the lower front end of the extraction device main body 1. A plurality of No. 1 bolts 17 are threadedly penetrated on the movable plate 18. After the internal environment of the extraction device main body 1 is safe, the No. 1 bolts 17 can be disassembled and the movable plate 18 can be removed to clean the inside;

[0036] When the accumulated sewage and coal ash on the load-bearing plate 2 reaches a certain weight, the load-bearing plate 2 will drive the telescopic rod 9 to move downward, and the spring 19 will be stretched during the movement. When the weight reaches a certain level, the secondary sewage outlet 14 and the main sewage outlet 7 are aligned to discharge the sewage. After the sewage is discharged, the weight becomes lighter, and multiple springs 19 rebound to move the load-bearing plate 2 upward. When the coal ash accumulates too much, it will cause the load-bearing plate 2 to move down to the contact sensor 5 to issue an alarm to remind the closing of the extraction channel. Subsequently, multiple No. 1 bolts 17 can be removed to remove the movable plate 18, and the long positioning block 6 and the short positioning block 3 can be disassembled from the inside to take out the No. 1 filter plate 4 to replace or clean it;

[0037] The multiple springs 19 have large elastic force and can be stretched to a long distance. After being stretched to a long distance, the multiple springs 19 can still slowly rebound and reset. The load-bearing plate 2 is light in weight. The load-bearing plate 2 can change its height position according to the weight of the sewage and coal ash received. It can rise again after the sewage is discharged. The lower ends of the two short positioning blocks 3 and the long positioning block 6 are fixedly arranged on the upper end of the No. 1 filter plate 4, so that the No. 1 filter plate 4 can be better fixed obliquely on the load-bearing plate 2, and the filter plate can be disassembled by removing the bolts on the short positioning blocks 3 and the long positioning blocks 6. The opening size of the secondary sewage outlet 14 is smaller than the opening size of the main sewage outlet 7, so that the secondary sewage outlet 14 can better discharge sewage when it moves down to the position of the main sewage outlet 7 with the load-bearing plate 2;

[0038] Filter plate No. 1 4 is placed at an angle, and a space is provided between filter plate No. 1 4 and the load-bearing plate 2, which can better realize the liquid-solid separation and removal of sewage and coal ash, and can more effectively carry out subsequent treatment and utilization. One side area of ​​the load-bearing plate 2 fits with the inside of one side of the extraction device body 1, and the other side area of ​​the load-bearing plate 2 fits with the inside of the other side of the extraction device body 1. While ensuring the good airtightness of the interior of the extraction device body 1, it is difficult for sewage to leak from the load-bearing plate 2 and the inner wall of the extraction device body 1. The sensor 5 will only issue an alarm reminder when it contacts the load-bearing plate 2, so that the sensor 5 can better receive the information that the load-bearing plate 2 bears too much weight, which is convenient for reminding to clean the coal ash and filter plate No. 1 4.

[0039] Working principle: The gas extraction pipe 13 is connected to the pipeline extending to the deep coal seam, and the gas extraction pipe 10 is connected to the gas extraction pump. When the gas is extracted from the deep coal seam, the water and coal slag and coal ash of the coal seam will enter the gas extraction pipe 13, and the gas will be extracted from the top by the gas extraction pipe 10. Impurities such as sewage and coal ash will fall onto the bearing plate 2, and impurities such as coal ash will be filtered by the first filter plate 4. The accumulated weight of sewage and coal ash on the bearing plate 2 will drive the telescopic rod 9 fixedly connected to the bearing plate 2 to pull the spring 19 downward, and then move it to the secondary sewage outlet 1. 4 is in contact with the main sewage outlet 7, and the sewage is immediately discharged. After the sewage is discharged, the mass is reduced, causing the load-bearing plate 2 to move up. After the load-bearing plate 2 has been drained for many times and the accumulated coal ash reaches a certain mass, the load-bearing plate 2 will move down to the contact sensor 5. At this time, an alarm is issued to remind cleaning. After closing the gas extraction pipe 13 and extracting the residual gas inside the extraction device body 1, after turning off the gas extraction pump, remove the No. 1 bolt 17 and move the movable plate 18, further remove the bolts on the internal short positioning block 3 and the long positioning block 6, and then take out the No. 1 filter plate 4 for replacement or cleaning.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
