Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal slurry water treatment technology, specifically to a coal slurry water impurity removal tank. Background Technology
[0002] Coal slurry is a high-concentration suspension of coal powder, slurry, and minerals generated during coal washing, mining, or processing. Existing methods for treating coal slurry present the following problems:
[0003] Coal slurry contains excessive flocculations such as cotton wool and fluff, as well as impurities such as clay. Its composition is complex, including coal particles of varying sizes, clay, sulfides, and other solid flocculations such as cotton wool and fluff, as well as impurities such as clay and residual flotation reagents.
[0004] This results in difficulties in cleaning existing coal slurry containing clumps of cotton wool, fluff, and other impurities, as well as clay and other impurities, leading to low filtration efficiency and easy accumulation and blockage of coal slurry in the tank. Utility Model Content
[0005] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a coal slurry water impurity removal tank to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a coal slurry water impurity removal tank, including two impurity removal tanks arranged in parallel. The top opening of the impurity removal tank and the side wall opening of the impurity removal tank are provided with filter ports. A detachable filter screen is installed in the impurity removal tank. A storage tank for storing filtered coal slurry water is provided at the bottom of the impurity removal tank.
[0007] The front end of the impurity removal tank is raised by 8 degrees to allow coal slurry water to pass through the filter screen.
[0008] Preferably, the filter screen is provided with handles on both sides.
[0009] The beneficial effects of this utility model are as follows: This utility model filters coal slurry water containing lint, fluff and other flocculations as well as clay and other impurities by setting two parallel impurity removal tanks. Even if one impurity removal tank is blocked, the other impurity removal tank can be used, which improves work efficiency. In addition, the impurity removal tanks are set at an 8-degree inclination so that the coal slurry water can pass through the filter screen.
[0010] This invention solves the problems of existing coal slurry water, such as the difficulty in cleaning clumps of cotton wool and lint, as well as impurities such as clay, low filtration efficiency, and easy accumulation and blockage of coal slurry water in the tank. Attached Figure Description

[0014] Explanation of the attached diagram labels: 1. Impurity removal tank; 2. Impurity filter port; 3. Filter screen; 4. Storage tank; 5. Handle. Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example:
[0017] like Figures 1-2 As shown, this utility model provides a coal slurry water impurity removal tank, including two impurity removal tanks 1 arranged side by side. The top opening of the impurity removal tank 1 and the side wall opening of the impurity removal tank 1 are provided with filter ports 2. A detachable filter screen 3 is installed in the impurity removal tank 1. A storage tank 4 for storing filtered coal slurry water is provided at the bottom of the impurity removal tank 1. Specifically, the storage tank 4 is located below the filter ports 2. The filter screen 3 can be detachably connected to the impurity removal tank 1 by bolts.
[0018] The front end of the impurity removal tank is raised by 8 degrees to allow coal slurry water to pass through the filter screen 3.
[0019] The filter screen 3 is provided with handles 5 on both sides to facilitate the removal of the filter screen 3. The handles 5 can be installed on the filter screen 3 by bolts.
[0020] Working principle:
[0021] In use, coal slurry containing lint, fluff, and other flocculated materials, as well as clay and other impurities, enters the impurity removal tank 1. The two impurity removal tanks 1 can be used separately or simultaneously. When used separately, if one impurity removal tank 1 becomes clogged, the other impurity removal tank 1 is activated. At this time, the filter screen 5 in the clogged impurity removal tank 1 is disassembled, removed, and cleaned. After cleaning, it is placed back into the impurity removal tank 1 for later use. The coal slurry water filtered by the filter screen 5 enters the storage tank 4 for later use.
[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
