Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a coal bed gas return liquid sewage treatment device. Background Art

[0002] Coalbed methane refers to the gas that is generated and stored in coal seams. Its main component is methane, so it is also called coalbed methane gas. During the exploration, development and utilization of coalbed methane, a large amount of drilling wastewater and sludge will be produced. These wastewaters have the characteristics of high mineralization and high salt content. If such wastewater is accidentally infiltrated into the soil, it will not only have a serious impact on the soil quality, but also pollute groundwater resources and cause great harm to people and animals in contact with it.

[0003] Regarding the sewage treatment of coalbed methane, a patent search revealed that a coalbed methane drilling sludge sewage treatment device with a publication number of CN218686860U can facilitate the cleaning of the filter by setting a replacement mechanism, thereby preventing impurities in the sewage from adhering to the surface of the filter, thereby avoiding affecting the filtering effect of the filter on the sewage. By setting a stirring mechanism, the purifier and the sewage can be fully stirred to avoid secondary pollution caused by the sewage, which greatly improves the practicality of the equipment. When the filter needs to be cleaned, the above-mentioned comparative document needs to take out the filter and the structural parts connected to the filter, and the filter needs to be installed later, which is inconvenient.

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-4 , including: a treatment box 1 and a filter inclined plate 2 arranged on one side of the treatment box 1. The use of the treatment box 1 and the mixing box 2 is the same as that of the comparative document. The flange channel on the top of the treatment box 1 is connected to the sewage pipe, and the sewage enters the cavity of the treatment box 1 along the flange channel. The flange channel is located on one side of the top of the treatment box 1, so that the sewage enters the position near one side of the top of the treatment box 1. Two groups of longitudinally spaced filter inclined plates 3 are arranged in the cavity of the treatment box 1. One end of the two groups of filter inclined plates 3 is connected to the inner wall of the treatment box 1, and the other end extends outward through the opening on the side of the treatment box 1, so that the filter inclined plates 3 are inclined, and the flange channel is located above the highest altitude of the filter inclined plates 3. Therefore, the sewage entering from the flange channel falls onto the filter inclined plates 3 and moves along the slope of the filter inclined plates 3. The outer wall of the treatment box 1 is fixed with a garbage collection bin 4 located below the filter inclined plates 3. The above structure is also used in the same way as that of the comparative document.

[0027] Also includes:

[0028] The filter rotating shaft 9 is arranged in the cavity of the treatment box 1, and a filter connecting plate 10 is fixedly arranged on the outer wall of the filter rotating shaft 9. The filter rotating shaft 9 is a columnar structure, and the filter connecting plate 10 is a plate-shaped structure fixedly arranged outside the filter rotating shaft 9. One end of the filter rotating shaft 9 is rotatably connected to the inner wall horizontal column of the treatment box 1, and the other end of the filter rotating shaft 9 extends outward through the treatment box 1. The outward extension of the filter rotating shaft 9 is connected to a group of worm gears 8, so that the worm gear 8 and the filter rotating shaft 9 can move synchronously, and a group of worms 6 are arranged on the worm gear 8, and the filter screen structure composed of the filter rotating shaft 9 and the filter connecting plate 10 is distributed along the transverse interval in the cavity of the treatment box 1, so that the filter connecting plate 10 is unfolded to form a filter screen. A filter screen structure is formed into a rectangular shape, and each group of filter screen structures composed of a filter rotating shaft 9 and a filter connecting plate 10 is connected to a group of worm gears 8. Therefore, as the worm 6 rotates, the worm 6 drives the worm gear 8 to rotate, which can rotate the filter rotating shaft 9. A first-level adjustment bin 5 is arranged outside the worm gear 8 and the filter rotating shaft 9. The first-level adjustment bin 5 is fixed to the surface of the processing box 1. One end of the worm 6 passes through the side wall of the first-level adjustment bin 5 and extends outward to be connected to a first-level operating handle 7. The worm 6 can be operated at the external first-level operating handle 7 to rotate, so that the filter screen can be manually adjusted. By rotating, the top surface of the filter screen can be rotated to a downward direction, so that the impurities remaining above the filter screen can fall off;

[0029] The garbage carrying plate 13 is arranged below the filtering rotating shaft 9 . A plurality of filter rotating shafts 9 and filter connecting plates 10 are arranged in a transversely spaced distribution along the groove of the processing box 1. A rectangular hole is provided at the front end of the processing box 1. The secondary regulating bin 12 is fitted with the rectangular hole, and the side wall of the secondary regulating bin 12 is slidably connected to the processing box 1. The garbage carrying plate 13 is arranged in a transversely spaced distribution along the surface of the secondary regulating bin 12, and a secondary operating handle 14 for driving the garbage carrying plate 13 to rotate is provided at one end of the secondary regulating bin 12. The internal structure of the secondary regulating bin 12 is the same as the internal structure of the primary regulating bin 5, and the rotation of the garbage carrying plate 13 can be completed by driving the secondary operating handle 14. After rotating to a horizontal state, the garbage carrying plate 13 is used to carry impurities falling from above, and when rotating to a vertical state, it is used for liquid discharge. Slide blocks are provided at both ends of the secondary regulating bin 12, and slide grooves are provided on both sides of the rectangular hole of the processing box 1, so that the secondary regulating bin 12 can slide back and forth in the rectangular hole. The secondary regulating bin 12 can be slid outward to complete the discharge of impurities, so that there is no need to take out the filter for cleaning, thereby reducing the difficulty of cleaning.

[0030] A cleaning socket 15 is provided on the surface of the secondary regulating chamber 12, and a cleaning rod 16 is inserted into the hole of the cleaning socket 15. A cleaning blade 17 located in the cavity of the processing box 1 is provided at the front end of the cleaning rod 16. In order to improve the cleaning efficiency of the filter, a group of cleaning blades 17 are provided above the secondary regulating chamber 12. The top of the cleaning blade 17 is in contact with the bottom of the filter. Therefore, by moving the cleaning rod 16 back and forth in the hole of the cleaning socket 15, the top of the cleaning blade 17 can scrape the filter, thereby causing impurities adhering to the surface of the filter to fall off.
