[0002] Coal washing water, as wastewater generated during the coal washing process, is mainly composed of a mixture of primary coal slime, secondary coal slime and water. Its composition is complex, including coal slime particles, minerals, clay particles, etc. The presence of these substances makes coal washing water not only have the properties of a suspension, but also have the properties of a colloid.

[0003] Most of the existing coal washing water treatment devices pour the coal washing water into a sedimentation tank and let it stand until the water and sediment are separated. The basic principle of this method is to use the gravity of the suspended matter in the coal washing water to make it settle naturally, thereby achieving the separation of water and sediment. After the water and sediment are separated, the upper layer of clear water is treated by other means to achieve the purpose of purification.

[0004] However, the static sedimentation method relies on natural gravity sedimentation, which results in a slow processing speed and cannot meet the needs of continuous water purification. Utility Model Content

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The coal washing water filtering device according to the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, the coal washing water filtering device of the embodiment of the utility model may include a shell 1, an inlet 2, a rotating drum 3, a driving mechanism 4, a collecting bucket 5, a plurality of filter plates 6, an inclined support plate 7, an agitating mechanism 8 and a valve 10.

[0024] The input port 2 is installed on the outer shell 1 , the rotating drum 3 is installed inside the outer shell 1 , and a plurality of rectangular grooves 31 are formed on the rotating drum 3 .

[0025] It can be understood that the input port 2 is used to input the washed coal into the filtering device for processing.

[0026] The driving mechanism 4 is installed on the housing 1 , and the driving mechanism 4 is connected to the rotating drum 3 .

[0027] It should be noted that, in this embodiment, the rotating drum 3 is used to screen out the coal blocks that cannot be purified in advance, leaving only the liquid for filtration.

[0028] The collecting barrel 5 is arranged at the bottom of the rotating drum 3 , the filter plate 6 is arranged at the bottom of the collecting barrel 5 , and a rotating bearing is arranged between the filter plate 6 and the collecting barrel 5 .

[0029] It should be noted that the solids are retained by the coal blocks, while the excess sewage flows from the filter plate 6 into the cavity formed by the two inclined support plates 7 .

[0030] Two inclined support plates 7 are installed at the bottom of the filter plate 6 , the stirring mechanism 8 is installed between the inclined support plates 7 , a drain port 9 is provided on one side of the inclined support plate 7 , and a valve 10 is provided between the drain port 9 and the inclined support plate 7 .

[0031] It can be understood that the stirring mechanism 8 is capable of disturbing the water to be purified and accelerating the adsorption of suspended matter in the water.

[0032] Specifically, when the coal washing water needs to be filtered, the coal washing water to be treated is put in from the input port 2, and then the coal washing water mixture passes through the rotating drum 3. The rectangular grooves 31 provided on the rotating drum 3 retain the solids that cannot pass through inside the rotating drum 3, and the liquid flows out from the rectangular grooves 31. At the same time, the driving mechanism 4 is turned on, the rotating shaft 42 drives the gear 41 to rotate, the gear 41 and the rectangular grooves 31 are engaged with each other, and the rotating drum 3 is driven to move to accelerate the solid-liquid separation.

[0033] When water flows from the filter plate 6 to the inside of the inclined support plate 7, the inclined support plate 7 will drive the water to flow downward, and the flocculant is put into the flocculation tube 84 in advance, and the flocculant contacts the liquid to react and precipitate. When the rotating disk 81 rotates, the clamping column 82 provided on the rotating disk 81 will drive the clamping ring 85 to move left and right, and the clamping ring 85 will drive the flocculation tube 84 to move left and right, disturbing the water and accelerating the sedimentation. When the sedimentation is completed, open the valve 10 to discharge the water directly from the discharge port.

[0034] In this way, the limitations of natural gravity sedimentation are overcome, and the processing speed of coal washing water can be increased, so that it can meet the requirements of clean water filtration more quickly, thereby meeting the needs of continuous clean water filtration.

[0035] In one embodiment of the present invention, Figure 1 As shown, the driving mechanism 4 may include a gear 41 and a rotating shaft 42 .

[0036] The rotating shaft 42 is installed in the middle of the gear 41, the rotating shaft 42 is connected to the output shaft of the rotating motor, and the tooth blocks on the gear 41 are engaged with the rectangular slots 31. At the same time, the arc length between the tooth blocks and the arc length between the plurality of rectangular slots 31 match each other.

[0037] It should be noted that, in this embodiment, the length of the rectangular groove 31 is greater than the length of the tooth block on the gear 41 , so that when the rotating motor drives the rotating shaft 42 to rotate, the screened water can flow out of the rectangular groove 31 .

[0038] In one embodiment of the present invention, Figure 3 As shown, the stirring mechanism 8 may include a rotating disk 81 , a clamping column 82 , a support rod 83 , a flocculation tube 84 , a clamping ring 85 and a limiting block 86 .

[0039] The clamping column 82 is mounted on the rotating disk 81, and the inner wall of the clamping ring 85 matches the clamping column 82. The support rod 83 is mounted on both sides of the clamping column 82, the support rod 83 is movably connected to the oblique support plates 7 on both sides, the limit block 86 is mounted on the end of the support rod 83, and the flocculation tube 84 is mounted on the clamping ring 85.

[0040] It should be noted that a motor capable of driving the rotating disk 81 to rotate is installed at the bottom of the rotating disk 81, such as a rotating motor. When the rotating disk 81 rotates, the clamping column 82 provided on the rotating disk 81 will combine with the clamping ring 85, thereby causing the clamping column 82 to drive the clamping ring 85 to move.

[0041] At the same time, the support rod 83 is extended and retracted inside the inclined support plates 7 on both sides, and the provided limit blocks 86 can move through the inclined support plates 7 to enable the clamping ring 85 to be located on the rotating disk 81 .

[0042] In one embodiment of the present invention, Figure 3 As shown, the flocculation tube 84 is detachably mounted on the clamping ring 85 .

[0043] It is understandable that the flocculation tube 84 can be rotatably connected to the clamp ring 85 to facilitate the replacement of the internal flocculant. At the same time, the flocculation tube 84 is provided with an opening for it to contact with the liquid.

[0044] As a possible situation, a feeding plate is provided on the flocculation tube 84, and the flocculant is directly fed from the feeding plate into the flocculation tube 84, and then the feeding plate and the flocculation tube 84 are closed by snapping.

[0045] In summary, the coal washing water filtration device of the embodiment of the utility model overcomes the limitations of natural gravity sedimentation, can improve the processing speed of coal washing water, and enable it to meet the requirements of clean water filtration more quickly, thereby meeting the needs of continuous clean water filtration.
