[0002] During the exploration, development and utilization of coalbed methane, a large amount of drilling wastewater and sludge are generated. This wastewater is characterized by high mineralization and high salinity. If this wastewater is accidentally seeped into the soil, it will not only seriously affect the soil quality, but also pollute groundwater resources and cause great harm to people and animals that come into contact with it. Therefore, it is necessary to treat coalbed methane drilling sludge and wastewater.

[0003] For example, publication number CN213950820U discloses a coalbed methane drilling sludge wastewater treatment device, which relates to the field of coalbed methane drilling technology. It includes a separation mechanism, a filtration mechanism, and a mixing mechanism. The bottom of the separation mechanism is fixedly connected to the filtration mechanism, and the bottom of the filtration mechanism is fixedly connected to the mixing mechanism. The separation mechanism includes a separation box, and the inner wall of the separation box is movably connected to a side plate. A drive box is fixedly installed on the inner side of the side plate.

[0004] In the above scheme, sludge and sewage are separated by a separation mechanism. However, in actual use, it was found that the amount of sludge gradually increases during the process, which can easily clog the mesh of the separation mechanism and reduce the separation efficiency of sludge and sewage. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the display module is easily damaged in the prior art, and once damaged, the staff needs to spend a lot of time to disassemble the display module, which affects the maintenance progress. Therefore, this invention proposes a coalbed methane drilling sludge and wastewater treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coalbed methane drilling sludge wastewater treatment device includes a treatment tank. A filter cylinder is provided on the top of the treatment tank. A fixing sleeve is fixedly provided on the wall of the filter cylinder. Support rods are provided on both sides of the fixing sleeve, and the lower ends of the support rods are fixedly connected to the inner side wall of the treatment tank. A rotating mechanism is provided between the fixing sleeve and the support rods. A support frame is fixedly provided on the top of the filter cylinder. A motor is fixedly provided on the top of the support frame. A scraper extending into the filter cylinder is fixedly provided at the output end of the motor. A filter screen is fixedly provided inside the treatment tank. An agitator extending into the treatment tank is detachably provided at the bottom of the scraper. A drain pipe is fixedly provided on the side wall of the treatment tank, and a switch valve is provided on the wall of the drain pipe.

[0008] Preferably, the rotating mechanism includes a mounting base, a rotating shaft, a limiting bolt, and a limiting plate. The mounting base is fixedly mounted on the end of the support rod. The mounting base and the fixed sleeve are rotatably connected via the rotating shaft. The limiting plate is fixedly mounted on the shaft wall of the rotating shaft. The limiting bolt is inserted into the side wall of the mounting base and threadedly connected to the limiting plate.

[0009] Preferably, the side wall of the limiting plate is provided with two screw holes symmetrically, and the end of the limiting bolt is threadedly connected to the screw hole.

[0010] Preferably, the scraper includes a U-shaped scraper, and a fixing rod is fixedly provided laterally inside the U-shaped scraper. A connecting rod connected to a motor is fixedly provided on the wall of the fixing rod.

[0011] Preferably, a sliding rod is fixedly provided at the bottom of the scraper, and a sliding sleeve is provided at the lower end of the sliding rod. The lower end of the sliding sleeve is inserted into the upper end of the agitator.

[0012] Preferably, a sludge and wastewater pipe extends from the top opening of the filter cartridge.

[0013] Compared with the prior art, this utility model provides a coalbed methane drilling sludge and wastewater treatment device, which has the following beneficial effects:

[0014] 1. This coalbed methane drilling sludge and wastewater treatment device, through the motor and the scraper, the motor can drive the scraper to rotate, so that the scraper rotates inside the filter cylinder and scrapes the inner wall, so that the sludge on the inner wall of the filter cylinder is scraped off, avoiding the clogging of the filter cylinder and improving the separation efficiency of sludge and wastewater.

[0015] 2. This coalbed methane drilling sludge and wastewater treatment device uses an agitator located at the lower end of the scraper. As the scraper rotates, it synchronously drives the agitator to rotate, ensuring that the wastewater and treatment agents inside the treatment tank are fully mixed, thus improving the wastewater treatment effect.

[0016] 2. This coalbed methane drilling sludge and wastewater treatment device, through the rotating shaft, limiting bolts and limiting discs set on both sides of the filter cylinder, when there is a lot of sludge inside the filter cylinder, the limiting bolts on both sides are loosened by wrench, so that the ends of the limiting bolts are unscrewed from the limiting disc. At this time, the position of the rotating shaft is released, which allows the filter cylinder to rotate through the rotating shafts on both sides and pour out the sludge inside.

[0017] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model has a structure for cleaning the inner wall of the filter cylinder, which avoids the phenomenon of sludge clogging the filter cylinder and improves the efficiency of separating sludge and sewage.

Detailed Implementation

[0023] 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.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Reference Figure 1 and 4A coalbed methane drilling sludge and wastewater treatment device includes a treatment tank 1, a filter cylinder 2 on top of the treatment tank 1, a sludge and wastewater pipe extending from the top opening of the filter cylinder 2, a fixing sleeve 3 fixedly mounted on the wall of the filter cylinder 2, support rods 4 on both sides of the fixing sleeve 3, and the lower end of the support rods 4 fixedly connected to the inner side wall of the treatment tank 1, and a rotating mechanism between the fixing sleeve 3 and the support rods 4; a support frame 5 fixedly mounted on the top of the filter cylinder 2, a motor 6 fixedly mounted on the top of the support frame 5, a scraper 7 extending into the filter cylinder 2 fixedly mounted on the output end of the motor 6, the scraper 7 including a U-shaped scraper 16, a fixing rod 17 fixedly mounted laterally inside the U-shaped scraper 16, and a connecting rod 18 connected to the motor 6 fixedly mounted on the wall of the fixing rod 17; a filter screen 8 fixedly mounted inside the treatment tank 1, a stirrer 9 extending into the treatment tank 1 detachably mounted on the bottom of the scraper 7, and a drain pipe 10 fixedly mounted on the side wall of the treatment tank 1, with a switch valve mounted on the wall of the drain pipe 10.

[0026] During the process, the sludge and wastewater are first discharged into the filter cylinder 2 through the sludge and wastewater pipe. The sludge and wastewater are separated by the filter cylinder 2. The separated sludge falls into the filter cylinder 2, while the wastewater falls into the treatment tank 1. The wastewater is then filtered through the filter screen 8 to remove impurities. During the sludge and wastewater separation process, the motor 6 is turned on. The motor 6 drives the scraper 7 to rotate, causing the scraper 7 to rotate inside the filter cylinder 2 and scrape the inner wall, thus scraping off the sludge on the inner wall of the filter cylinder 2. This prevents the filter cylinder 2 from becoming clogged and improves the efficiency of separating sludge and wastewater.

[0027] Reference Figure 1-3 The rotating mechanism includes a mounting base 11, a rotating shaft 12, a limiting bolt 13, and a limiting plate 14. The mounting base 11 is fixedly mounted on the end of the support rod 4. The mounting base 11 and the fixed sleeve 3 are rotatably connected through the rotating shaft 12. The limiting plate 14 is fixedly mounted on the shaft wall of the rotating shaft 12. The limiting bolt 13 is inserted into the side wall of the mounting base 11 and threadedly connected to the limiting plate 14. The side wall of the limiting plate 14 is symmetrically provided with two screw holes 15. The ends of the limiting bolts 13 are threadedly connected to the screw holes 15. When there is a lot of sludge inside the filter cylinder 2, the limiting bolts 13 on both sides are loosened by wrench, so that the ends of the limiting bolts 13 are unscrewed from the limiting plate 14. At this time, the position of the rotating shaft 12 is released, allowing the filter cylinder 2 to rotate at an angle through the rotating shafts 12 on both sides and pour out the sludge inside.

[0028] Reference Figure 1 The bottom of the scraper 7 is fixedly provided with a sliding rod 19, and the lower end of the sliding rod 19 is provided with a sliding sleeve 20. The lower end of the sliding sleeve 20 is inserted into the upper end of the stirrer 9. Before the filter cylinder 2 is moved, the sliding sleeve 20 needs to be pushed up so that the lower end of the sliding sleeve 20 is pulled out from the upper end of the stirrer 9, thereby ensuring that the filter cylinder 2 can be rotated.

[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.
