Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a reverse osmosis concentrated water treatment device for coal chemical industry. Background Technique

[0002] The treatment process of reverse osmosis concentrated water in coal chemical industry is a complex and delicate process, aiming to remove high salinity, organic matters and other pollutants in the concentrated water. The treatment steps are: adjusting water quality, removing suspended solids, advanced oxidation treatment, membrane treatment, evaporation crystallization, biochemical treatment, water quality monitoring, and discharging or reusing.

[0003] The inventor found that the following problems in the prior art have not been well solved in the process of realizing the above process of removing suspended solids: in actual operation, if the pretreatment process of the coal chemical wastewater treatment system is imperfect or the operation management is improper, some large particle impurities (such as leaves, paper scraps, etc.) may enter the reverse osmosis treatment system. In addition, if there is a large amount of garbage such as plastics in the surrounding environment of the wastewater treatment system and these garbage are not effectively treated or isolated, they may also enter the wastewater treatment system through a certain way. When these garbage enter the sedimentation treatment tank through adjusting water quality, pump groups and pipelines for suspended solid treatment, the treatment process cannot precipitate them, and it is very easy to be blocked when discharging into the next treatment tank. There are two traditional methods. One is manual fishing, but the intensity is large and the steps are cumbersome; the other is to set up a grid grille. However, since some drain pipes of the regulating tank drain into the water inlet pipe of the sedimentation tank, and the water inlet pipe of this sedimentation tank is in the middle or lower part of this treatment tank, it is difficult to remove the sundries filtered and collected in the grille. After the sewage in this tank is treated and discharged, workers need to go down into the tank for disassembly and cleaning, resulting in a more onerous overall work. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a reverse osmosis concentrated water treatment device for coal chemical industry, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A coal chemical reverse osmosis concentrated water treatment device includes a sedimentation tank and a handle. A plurality of sewage pipes are arranged on the sedimentation tank. A sleeve cover is provided at one end of the bottom of each sewage pipe located inside the sedimentation tank. A net cylinder is fixed to the bottom of each sleeve cover. Connecting ears are fixed to both ends of the outside of the net cylinder. Jacks are drilled at the bottoms of the connecting ears, and screw grooves are drilled at the tops of the connecting ears. Supports are arranged below the connecting ears. Mounting plates are fixed to the tops of the supports. Guide rails are fixed to the tops of the mounting plates. Sliders are slidably connected to the tops of the guide rails. Elastic members are fixed to the tops of the sliders. Plug rods are fixed to the telescopic ends of the elastic members. The number of handles is two, and screw teeth are provided on the outer walls of the bottoms of the handles.

[0007] Preferably, the sleeve covers are respectively connected to the outer walls of the bottoms of the sewage pipes.

[0008] Preferably, the inner diameter of the sleeve cover is larger than the outer diameter of the bottom of the sewage pipe, and the difference between the two diameters is between 0.5 cm and 1 cm.

[0009] Preferably, the handles are respectively threadedly connected to the screw grooves at the matching positions through the screw teeth at the bottoms.

[0010] Preferably, the ends of the plug rods away from the elastic members are respectively inserted into the interiors of the jacks.

[0011] Preferably, the supports are respectively installed inside the sedimentation tank through bolts.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] The sewage with adjusted water quality enters the interior of the sedimentation tank through the sewage pipes. After being treated by the sewage pipes, the sewage enters the net cylinder. The sleeve cover and the net cylinder form a container that is nearly closed in the upper half and can leak water in the lower half. Some large-particle sundries can be filtered by it, and the sewage is directly discharged into the sedimentation tank. After the sedimentation treatment is completed and discharged, the staff can insert the handle into the screw groove and threadedly connect it by rotation. Then, by pressing the handle, the elastic member is compressed and lowered, so that the sleeve cover is withdrawn from the bottom of the sewage pipe. Subsequently, by pushing the handle, the slider slides on the guide rail and drives the sleeve cover and the net cylinder away from the vertical position of the sewage pipe. Finally, by lifting the handle, the sleeve cover and the net cylinder are pulled out of the sewage pipe, and the disassembly work can be completed. Therefore, the present application not only has a good filtering effect, but also avoids the cumbersome problems of manual fishing and manual entry into the pool to disassemble the filter element.

Specific implementation mode

[0020] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model is further elaborated below in conjunction with specific implementation modes.

[0021] As Figures 1-5 shown, a reverse osmosis concentrated water treatment device for coal chemical industry includes a sedimentation tank 1 and a handle 12. A plurality of sewage discharge pipes 2 are arranged on the sedimentation tank 1. Sleeve caps 3 are arranged at the bottom ends of the sewage discharge pipes 2 located inside the sedimentation tank 1. Mesh cylinders 4 are fixedly arranged at the bottoms of the sleeve caps 3. Connecting ears 5 are fixedly arranged at both outer ends of the mesh cylinders 4. Jacks 51 are drilled at the bottoms of the connecting ears 5. Screw grooves 52 are drilled at the tops of the connecting ears 5. Brackets 6 are arranged below the connecting ears 5. Mounting plates 7 are fixedly arranged at the tops of the brackets 6. Guide rails 8 are fixedly arranged at the tops of the mounting plates 7. Sliders 9 are slidably connected to the tops of the guide rails 8. Elastic members 10 are fixedly arranged at the tops of the sliders 9. Inserting rods 11 are fixedly arranged at the telescopic ends of the elastic members 10. The number of the handles 12 is two, and screw teeth 13 are arranged on the outer walls of the bottoms of the handles 12.

[0022] Specifically, the sleeve caps 3 are respectively connected to the outer walls of the bottoms of the sewage discharge pipes 2.

[0023] Specifically, the inner diameter size of the sleeve cap 3 is larger than the outer diameter size of the bottom of the sewage discharge pipe 2, and the difference between the two sizes is between 0.5 cm and 1 cm, so that the sleeve cap 3 can be easily sleeved on the outer wall of the sewage discharge pipe 2, and at the same time, large debris can be filtered.

[0024] Specifically, the handles 12 are respectively threadedly connected to the screw grooves 52 at the matching positions through the screw teeth 13 at the bottoms, and the operation during disassembly can be carried out.

[0025] Specifically, one end of the insertion rod 11 away from the elastic member 10 is respectively inserted into the inside of the insertion hole 51. The insertion of the two can enable the elastic member 10 to jack up the net cylinder 4, so that the sleeve cover 3 can be stably sleeved on the outer wall of the sewage pipe 2.

[0026] Specifically, the brackets 6 are respectively installed inside the sedimentation tank 1 through bolts, and can support the sleeve cover 3 and the net cylinder 4 during filtration.

[0027] Specifically, an annular flange with a trapezoidal cross-section is provided on the upper part of the inner side of the sleeve cover 3, which forms an interference fit with the annular groove on the outer wall of the bottom of the sewage pipe 2, and the fit tolerance is H8 / f7.

[0028] Working principle:

[0029] The sewage with adjusted water quality enters the inside of the sedimentation tank 1 through the sewage pipe 2. The sewage enters the net cylinder 4 after being treated by the sewage pipe 2. The sleeve cover 3 and the net cylinder 4 form a container with an upper half part close to being closed and a lower half part that can leak water. Some large-particle sundries can be filtered by it, and the sewage is directly discharged into the sedimentation tank 1. After the sedimentation treatment is completed and discharged, as Figure 2 shown, the staff can insert the handle 12 into the screw groove 52 and rotate it to be threadedly connected therewith, and then compress and lower the elastic member 10 by pressing the handle 12, so that the sleeve cover 3 is withdrawn from the bottom of the sewage pipe 2, as Figure 3 shown, push the handle 12, so that the slider 9 slides on the guide rail 8 and drives the sleeve cover 3 and the net cylinder 4 away from the vertical position of the sewage pipe 2, as Figure 4 shown, lift the handle 12 to drive the sleeve cover 3 and the net cylinder 4 out of the sewage pipe 2, and the disassembly work can be completed. Therefore, the present application not only has a good filtering effect, but also does not require the cumbersome problems of manual fishing and manual entry into the pool to disassemble the filter element.
