Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an integrated mine wastewater treatment equipment. Background Technology

[0002] Mine wastewater contains large amounts of coal dust, rock dust, and colloidal suspended solids, which are characterized by small particle size, low specific gravity, and slow settling, making them difficult to separate efficiently using traditional sedimentation processes. Long-term accumulation of sludge not only occupies treatment facility space but also releases heavy metals and organic matter, causing secondary pollution of water sources.

[0003] Filter presses are widely used in wastewater treatment, especially for wastewater containing a large amount of sludge. Filter presses can filter out the sludge from the wastewater and compress it into sludge cakes, which not only achieves good solid-liquid separation, but also reduces the burden of sludge transportation and landfill.

[0004] For example, the invention patent with publication number CN118290001A discloses a belt filter press, which is equipped with an upper filter belt and a lower filter belt, and uses multiple steering rollers to drive the upper filter belt and the lower filter belt, thereby realizing the filtration and compression of sludge, allowing the sludge to be separated from the sewage in the form of sludge cake.

[0005] The above-mentioned technical solution lacks a mechanism for uniformly distributing the sewage-sludge mixture. The uneven distribution of the sewage-sludge mixture entering between the upper and lower filter belts not only makes the upper and lower filter belts prone to wrinkling, but also affects the uniformity of sludge compression by the device, thus reducing the sewage treatment efficiency. Summary of the Invention

[0006] In view of this, the present invention proposes an integrated mine wastewater treatment equipment that can uniformly distribute wastewater and sludge, thereby improving the separation efficiency of water in the wastewater and sludge mixture.

[0013] Based on the above technical solutions, preferably, the fabric feeder further includes multiple adjusting shafts and multiple bevel gears. The adjusting shafts are rotatably mounted on the control box and correspond one-to-one with them.

[0036] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] Mine wastewater contains a large amount of coal dust, rock dust, and colloidal suspended solids and other sludge. In order to improve the wastewater treatment efficiency, the wastewater needs to be transported to a sedimentation tank for sedimentation to achieve initial separation of the water. Then, solid-liquid separation equipment is used to separate the wastewater and sludge mixture located at the bottom of the sedimentation tank.

[0038] The integrated mine wastewater treatment equipment of the present invention includes a frame 1, two filter press belts 2, a conveyor belt 3, a distributor 4, a washing tank 5 and a distribution box 6, which is used to perform solid-liquid separation of wastewater and sludge mixture and improve the wastewater treatment efficiency.

[0039] Both the filter press belt 2 and the conveyor belt 3 are mounted on the frame 1, with the two filter press belts 2 positioned opposite each other, one above the other. The conveyor belt 3 is located on one side of the two filter press belts 2. The material distribution box 6 is fixedly mounted on the frame 1, and a material leakage trough 601 is provided on one side of the material distribution box 6. The material leakage trough 601 is located above the conveyor belt 3. Figure 1 and Figure 2 As shown, after the sewage sludge mixture is added to the feeding box 6, it first flows through the discharge chute 601 onto the conveyor belt 3, and then is conveyed by the conveyor belt 3 to the filter press belt 2 located below. Finally, it moves between the two filter press belts 2 and is squeezed by the two filter press belts 2. Since the surfaces of the filter press belt 2 and the conveyor belt 3 are both hollow, the water in the sewage sludge mixture will pass through the filter press belt 2 and the conveyor belt 3 and flow down to the bottom of the equipment, while the sludge in the sewage sludge mixture will be filtered and squeezed by the two filter press belts 2 to form a sludge cake, thus realizing the solid-liquid separation of the sewage sludge mixture.

[0040] like Figure 10 As shown, the conveyor belt 3 includes multiple rotating rollers 31 and a conveyor belt 32. The rotating rollers 31 are rotatably mounted on the frame 1, and the conveyor belt 32 is fitted between the multiple rotating rollers 31. The conveyor belt 32 is an annular belt structure with a hollowed-out surface, and the material discharge trough 601 is located on the top side of the conveyor belt 32. When the rotating rollers 31 are connected to the drive equipment and rotate, they can drive the conveyor belt 32 to rotate, thereby realizing the conveying of the sewage and sludge mixture.

[0041] During the process of conveying the sewage and sludge mixture by the conveyor belt 3, the sewage and sludge mixture is located on the top side of the conveyor belt 32, and the water in the sewage and sludge mixture drips down through the top side of the conveyor belt 32 to the bottom side of the conveyor belt 32, thereby cleaning the conveyor belt 32.

[0042] like Figure 10 As shown, the cleaning box 5 is also used to clean the conveyor belt 32. The cleaning box 5 is fixedly installed on the frame 1. The top side of the cleaning box 5 has an opening. Part of the conveyor belt 32 is located inside the cleaning box 5. During the rotation of the conveyor belt 32, the conveyor belt 32 can be cleaned by the cleaning water in the cleaning box 5, so that the conveyor belt 32 is kept clean.

[0043] like Figure 2 , Figure 11 and Figure 12 As shown, the structure and principle of the filter press belt 2 are the same as those of the conveyor belt 3, thus enabling the rotation of the filter press belt 2. The top side of the lower filter press belt 2 abuts against the bottom side of the upper filter press belt 2. When the sewage and sludge mixture passes through the abutting position of the two filter press belts 2, the water can be squeezed and separated from the sewage and sludge mixture, thereby forming a sludge cake. The abutting position of the two filter press belts 2 is S-shaped, which can improve the squeezing efficiency of the filter press belt 2 on the sewage and sludge mixture.

[0044] like Figure 2 and Figure 10 As shown, the top side of the conveyor belt 32 is inclined at an angle of 5-10 degrees. The end of the top side of the conveyor belt 32 away from the filter press belt 2 is located below the end of the top side of the conveyor belt 32 near the filter press belt 2. When the sewage sludge mixture is conveyed by the conveyor belt 32, the water seeping out inside it will flow away from the filter press belt 2, which helps to improve the solid-liquid separation efficiency of the sewage sludge mixture.

[0045] The filter press belt 2 is usually made of plastic. When the two filter press belts 2 compress the sewage and sludge mixture, the filter press belt 2 is prone to bending and wrinkling. The distributor 4 is located between the filter press belt 2 and the distributor box 6. It is used to evenly distribute the sewage and sludge mixture on the conveyor belt 3, so that the sewage and sludge mixture enters the space between the two filter press belts 2 evenly, thereby improving the sewage treatment efficiency.

[0046] The material feeder 4 includes a mounting frame 41, multiple fixed shafts 42, and multiple first discs 43. The mounting frame 41 is fixedly mounted on the frame 1, the fixed shafts 42 are mounted on the mounting frame 41, and the multiple fixed shafts 42 are arranged parallel and spaced apart. The first discs 43 are fixedly mounted on the fixed shafts 42 and correspond one-to-one with them. The periphery of the first disc 43 is arc-shaped and abuts against the top side of the conveyor belt 3. Figure 3As shown, two adjacent first discs 43 abut against each other, and the two adjacent first discs 43 and the conveyor belt 3 enclose a channel for the passage of sewage and sludge mixture. Multiple channels divide the originally integral sewage and sludge mixture into multiple strip structures. There are grooves between the multiple strip structures so that water can seep out from the strip structures. Since the cross-section of the strip structures is uniform and constant, and the cross-sections of multiple strip structures are the same, when the two filter press belts 2 squeeze the multiple strip structures, the strip structures will deform and fill the filter press belts 2, thereby making the sludge form a uniform cake structure to achieve the uniformity of sewage and sludge mixture treatment.

[0047] like Figure 3 As shown, the cross-section of the channel formed by the first disc 43 and the conveyor belt 3 is similar to a triangle, with a straight base and two inwardly curved arcs on the left and right sides. This shape can reduce the accumulation of sewage and sludge mixture, help improve the seepage efficiency of water in the sewage and sludge mixture, and improve the extrusion deformation effect of the strip structure.

[0048] Preferably, the fixed shaft 42 is rotatably mounted on the mounting bracket 41 to rotate the first disc 43. To make the periphery of the first disc 43 arc-shaped, it can be configured as a circle or an ellipse, etc.

[0049] When the first disc 43 is circular, the first disc 43 can be rotated by rotating the fixed shaft 42, so that different positions of the first disc 43 come into contact with the sewage sludge mixture, thus extending the service life of the first disc 43.

[0050] The smaller the width and the greater the height of the strip structure, the better the infiltration effect of water in the sewage sludge mixture. However, when treating different types of sewage, the humidity and viscosity of the sewage sludge mixture will vary. If the humidity of the sewage sludge mixture is high and the viscosity is low, the strip structure formed by the channel will collapse rapidly, affecting the uniformity of the sewage sludge mixture distribution.

[0051] When the first disk body 43 is elliptical, such as Figure 4 As shown, rotating the fixed shaft 42 can drive the first disc 43 to rotate. At this time, the cross-sectional shape, width and height of the channel formed by the two adjacent first discs 43 and the conveyor belt 3 all change, thereby adapting to sewage and sludge mixtures with different humidity and viscosity, and avoiding problems such as rapid collapse of the formed strip structure.

[0052] like Figure 2 As shown, the first disc 43 is located at the end of the fixed shaft 42 away from the filter belt 2, thereby preventing the sewage and sludge mixture from contacting the fixed shaft 42 and protecting the fixed shaft 42.

[0053] When the first disc 43 is elliptical and rotates, the distance between the periphery of the first disc 43 and the top side of the conveyor belt 3 will change, and the distance between two adjacent first discs 43 will also change. In order to ensure that the first disc 43 can always contact the top side of the conveyor belt 3 when rotating, and to keep two adjacent first discs 43 in contact, the mounting bracket 41 is configured to include two bushings 411, multiple control boxes 412, sleeves 413, slide rods 414, two springs 415 and two fixing bolts 416.

[0054] like Figure 3 and Figure 5 As shown, bushing 411 is fixedly mounted on frame 1, multiple control boxes 412 are spaced apart between two bushings 411, fixed shaft 42 is rotatably mounted on control box 412, sleeve 413 and slide rod 414 are respectively fixedly mounted on both sides of control box 412, and sleeve 413, slide rod 414, fixed shaft 42 correspond one-to-one with control box 412, adjacent slide rod 414 and sleeve 413 are slidably connected, slide rod 414 and sleeve 413 located at the same end of multiple control boxes 412 are respectively rotatably and slidably mounted in two bushings 411; the sliding cooperation between slide rod 414 and sleeve 413 and the sliding cooperation between slide rod 414 and sleeve 413 and bushing 411 makes two adjacent first discs 43 keep in contact, and the rotational cooperation between slide rod 414 and sleeve 413 and bushing 411 makes the first disc 43 keep in contact with the top side of conveyor belt 3.

[0055] Spring 415 is abutting between bushing 411 and control box 412, and multiple control boxes 412 are located between two springs 415, such as Figure 1 As shown, in its natural state, the two springs 415 support the control boxes 412 located at both ends, so that the two adjacent first discs 43 can always remain in contact, ensuring the consistency of the channel formed by the first discs 43 and the conveyor belt 3.

[0056] like Figure 5 As shown, the fixing bolts 416 are connected to the bushings 411 by threaded connection. The fixing bolts 416 and bushings 411 correspond one-to-one, and the two fixing bolts 416 respectively abut against the sliding rod 414 and the sleeve 413 inside the bushings 411. When the fixing bolts 416 are loosened, the sliding rod 414 and the sleeve 413 can be rotated. When the sliding rod 414 and the sleeve 413 are rotated to the appropriate position, the fixing bolts 416 are tightened so that the fixing bolts 416 abut against and fix the sliding rod 414 and the sleeve 413.

[0057] The feeder 4 also includes multiple rotating drums 44 and multiple second discs 45. The rotating drums 44 are sleeved on the outside of the fixed shaft 42 and rotatably connected to it. The second discs 45 are fixedly mounted on the rotating drums 44. The second discs 45 are located on the side of the first disc 43 near the filter belt 2, and the second discs 45 are also sleeved on the periphery of the fixed shaft 42. The second discs 45 are rotatably connected to the fixed shaft 42. The second discs 45, the first discs 43, the rotating drums 44 and the fixed shaft 42 correspond one-to-one. The second discs 45 and the first discs 43 have the same shape. The axis of the rotating drum 44 coincides with the axis of the fixed shaft 42, and the center points of the second discs 45 and the first discs 43 are both located on the axis of the fixed shaft 42. The first discs 43, the second discs 45 and the conveyor belt 3 are used to form a channel for uniformly distributing the sewage and sludge mixture.

[0058] like Figure 8 and Figure 9 As shown, when the first disc 43 rotates at a certain angle, the second disc 45 rotates in the opposite direction at the same angle, so that the channel formed by the first disc 43, the second disc 45 and the conveyor belt 3 together forms a symmetrical structure, which improves the symmetry of the strip structure formed by the sewage sludge mixture and the uniformity of the sludge cake compression.

[0059] The fabric feeder 4 also includes multiple adjusting shafts 46 and multiple bevel gears 47. The adjusting shafts 46 are rotatably mounted on the control box 412 and perpendicular to the fixed shaft 42. Each adjusting shaft 46 corresponds one-to-one with the fixed shaft 42 and the control box 412. The bevel gears 47 are respectively fixedly mounted on the adjusting shafts 46, the fixed shaft 42, and the rotating drum 44, with the bevel gears 47 on the adjusting shafts 46 meshing between the bevel gears 47 on the fixed shaft 42 and the bevel gears 47 on the rotating drum 44. Figure 7 As shown, when the adjusting shaft 46 is rotated, the three bevel gears 47 can be used to make the fixed shaft 42 and the rotating drum 44 rotate in opposite directions, so that the first disc 43 and the second disc 45 rotate in opposite directions by the same angle, making the channel formed by the first disc 43, the second disc 45 and the conveyor belt 3 symmetrical.

[0060] To improve the ease of operation of the device, a synchronous drive device can be used to synchronously drive multiple adjusting shafts 46.

[0061] The working principle of the integrated mine wastewater treatment equipment of the present invention is as follows:

[0062] The sewage-sludge mixture in the distribution box 6 first flows evenly down the discharge chute 601 to the top side of the conveyor belt 32, then is separated into multiple strip structures by the distributor 4, and finally conveyed between two filter press belts 2 for compression. The water in the sewage-sludge mixture drips through the filter press belt 2 and the conveyor belt 32 to the bottom of the device, while the sludge in the sewage-sludge mixture is compressed by the two filter press belts 2 to form a sludge cake, thus achieving solid-liquid separation of sewage. During this process, the cross-section of the strip structure is similar to a triangle, which makes it easier for the water in the sewage-sludge mixture to seep out. At the same time, the uniform cross-section of the strip structure helps to improve the uniformity of the sewage-sludge mixture being compressed by the two filter press belts 2.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
