Description

Technical Field

[0001] The utility model relates to the technical field of mine water treatment, in particular to a filtering device for mine water treatment. Background Art

[0002] Mine water is generally produced in coal mines. Mine water contains organic pollutants such as waste oil and emulsified oil. The total ion content in mine water is much higher than that in general surface water, and a large part of it is sulfate ions. Mine water often has a very low pH value and is often accompanied by a large amount of ferrous ions, which increases the difficulty of treatment. At present, the mine water treatment devices on the market generally need to add sedimentation agents when filtering mine water to completely precipitate and filter the heavy metal substances in the mine water before filtering.

[0003] A patent document with publication number CN219489641U discloses a high-efficiency filtration mine water treatment device, which provides a forward stirring plate and a reverse stirring plate, so that the mine water entering the treatment cylinder can be stirred forwardly and reversely at the same time to be fully mixed with the sedimentation agent, thereby improving the filtration treatment efficiency. In the process of implementing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above device is actually used, the two sets of stirring plates are used to rotate forward and reverse, which improves the mixing efficiency of the mine water and the sedimentation agent. However, after the mine water and the sedimentation agent are fully mixed, the stirring needs to be stopped to allow the mine water to stand for a period of time. The mixing of the mine water and the sedimentation agent and the standing of the mixed mine water cannot be carried out simultaneously, and the problem of low treatment efficiency still exists. Moreover, before the mine water is mixed, it does not have the effect of screening out large impurities, which is inconvenient to use.

[0005] Therefore, it is necessary to provide a filtering device for mine water treatment to solve the above technical problems. Utility Model Content

[0020] The mine water and the sedimentation agent enter the processing box 1, the sieve plate 2 filters the larger impurities in the mine water, and the impurities are left on the top of the sieve plate 2. The impurities on the sieve plate 2 can be automatically pushed away by the pushing component 3 to avoid clogging of the sieve plate 2. The first motor 4 drives the stirring rod 6 to rotate through the rotating rod 5 to quickly stir the mine water and the sedimentation agent to ensure that the mine water and the sedimentation agent are fully mixed. After fully mixed, the electric control valve 8 is opened through the external controller, and the mine water enters the sedimentation box 9 through the drainage pipe 7 for static, and the electric control valve is closed. Mine water and sedimentation agent can continue to be added and mixed behind door 8. After the mine water in the sedimentation box 9 has been standing for a period of time, the clean water in the middle and upper part of the sedimentation box 9 is discharged through the discharge pipe 10, and then the sedimentation box 9 is pulled out to clean the sediment at the bottom. After the cleaning is completed, the sedimentation box 9 is pushed into the treatment box 1. At this time, the mine water and sedimentation agent in the treatment box 1 have been fully mixed, and the mine water can continue to be standing, so that the mine water can be continuously treated, which greatly improves the treatment effect.

[0027] When in use, the mine water and the sedimentation agent enter the processing box 1, the sieve plate 2 filters the larger impurities in the mine water, and the impurities are left on the top of the sieve plate 2. The second motor 31 drives the screw rod 32 to rotate, and the screw rod 32 rotates in the sieve plate 2 to make the push plate 33 move in the moving groove 34, so that the push plate 33 pushes the impurities on the sieve plate 2 to the side opening of the processing box 1, and the impurities on the sieve plate 2 are automatically cleaned to avoid clogging of the sieve plate 2. The first motor 4 drives the stirring rod 6 to rotate through the rotating rod 5 to quickly stir the mine water and the sedimentation agent to ensure that the mine water and the sedimentation agent are fully mixed. After being fully mixed, the external control The device opens the electric control valve 8, and the mine water enters the settling box 9 through the drainage pipe 7 for standing. After closing the electric control valve 8, mine water and settling agent can continue to be added and mixed. After the mine water in the settling box 9 stands for a period of time, the clean water in the middle and upper part of the settling box 9 is discharged through the discharge pipe 10, and then the settling box 9 is pulled out to clean the sediment at the bottom. After the cleaning is completed, the settling box 9 is pushed into the treatment box 1.
