Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mud cleaning device for sewage treatment. Background Art

[0002] With the rapid development of industry and the acceleration of urbanization, the amount of sewage discharge has increased dramatically. Sewage contains a large amount of suspended solids, organic matter and other pollutants, which will gradually settle to form sludge during the treatment process. If these sludges are not cleaned up in time, they will occupy the effective volume of the sewage treatment facilities and reduce the efficiency of sewage treatment. For example, in urban domestic sewage treatment plants, a large amount of sludge accumulation will lead to a decrease in the treatment capacity of treatment units such as sedimentation tanks and aeration tanks, affecting the stable operation of the entire sewage treatment plant. Moreover, long-term accumulation of sludge may also cause secondary pollution, releasing unpleasant odors and harmful gases, affecting the quality of the surrounding environment and the lives of residents.

[0003] At present, the commonly used sludge removal methods in sewage treatment plants include manual sludge removal and some traditional mechanical sludge removal equipment. Manual sludge removal is labor-intensive, inefficient and poses safety hazards. Operators need to work in a harsh sewage environment, and long-term exposure to sewage and sludge may cause damage to their health. Traditional mechanical sludge removal devices, such as scrapers, although they have improved the sludge removal efficiency to a certain extent, have the problem of incomplete sludge removal.

[0004] Therefore, the utility model provides a mud cleaning device for sewage treatment to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a mud cleaning device for sewage treatment, such as Figures 1 to 5As shown, it includes a back plate 1, a transition slope 101 is provided on one side of the upper surface of the back plate 1, side plates 2 are fixedly installed on both sides of the front of the back plate 1 by bolts, a cross bar 3 is fixedly installed on the middle of the inner wall of the side plate 2 by bolts, a bearing seat 4 is fixedly installed on the middle of one side surface of the cross bar 3, a shaft rod 5 is movably connected to one side of the bearing seat 4, one end of the shaft rod 5 is movably connected to the first mud pressing roller 6, the outer arc surface of the first mud pressing roller 6 is provided with a forming groove A7, a driving gear 8 is fixedly installed on the end of the shaft rod 5 close to the first mud pressing roller 6, and the outer arc surface serration of the driving gear 8 is meshed with a driven gear 9, and the driven gear A second mud pressing roller 10 is fixedly installed on one side of the wheel 9 through the shaft 5. The outer arc surface of the second mud pressing roller 10 is provided with a forming groove B11, and the forming groove B11 is meshed with the forming groove A7. There are three cross bars 3, which are installed on the side plates 2 in sequence. Both ends of the bearing seat 4 are fixedly installed on two of the cross bars 3. The transition slope 101 and the first mud pressing roller 6 and the second mud pressing roller 10 are located in the same plane. A filter bottom plate 12 is fixedly installed on the bottom of the back plate 1. The filter bottom plate 12 is placed below the first mud pressing roller 6. Both sides of the filter bottom plate 12 are fixed to the bottom of the two side plates 2 by screws.

[0027] During the process of filtering sewage, it flows onto the back plate 1. Due to the special structure of the transition slope 101 at the front end of the back plate 1, the washed sludge will fall into the machine in the direction of the water flow. At the same time, before the sludge enters, the driving gear 8 will be driven by the motor. The rotation of the driving gear 8 will cause the meshed driven gear 9 to rotate relative to each other, so the connected first mud pressing roller 6 and the second mud pressing roller 10 will also rotate relative to each other. A forming groove A7 and a forming groove B11 are provided between the two mud pressing rollers, and the forming grooves A7 and the forming grooves B11 are evenly distributed between each mud pressing roller. The sizes of the forming grooves are all standard structures. The grooves of the two rollers are staggered and embedded with each other. The sludge entering between the two rollers during operation can form mud blocks through the forming groove A7. After the sludge is compacted into blocks, the volume will be significantly reduced. Generally speaking, untreated sludge has a high water content and is loose, taking up a lot of space. Compared with treating loose sludge, cleaning is simpler and faster.

[0028] One side of one cross bar 3 is rotatably connected to a transmission screw 13 through a bearing seat 4, and the outer arc surface of the transmission screw 13 is threadedly connected to a mounting seat 14, and a connecting bracket 15 is fixedly installed on the front of the mounting seat 14 by bolts. A load-bearing end is provided at the bottom of one side surface of the connecting bracket 15, and a connecting vertical plate 16 is fixedly installed on the upper surface of the connecting bracket 15 through the load-bearing end. A latch 17 is installed through the surface of one side of the connecting vertical plate 16, and a torsion spring 18 is fixedly sleeved on the outer arc surface of the latch 17. Both ends of the torsion spring 18 are abutted and connected with a trapezoidal bracket 19, and a brush head assembly 20 is fixedly installed on the lower surface of the trapezoidal bracket 19. The brush head assembly 20 includes a mud cleaning brush 201 fixedly installed directly below the trapezoidal bracket 19, a spray head 202 on the side of the trapezoidal bracket 19 close to the mud cleaning brush 201, and a water absorbing part 203 on the side of the trapezoidal bracket 19 close to the spray head 202. The brush head assembly 20 fits snugly with the filter bottom plate 12.

[0029] When the mud cleaning operation is started, the transmission screw 13 drives the entire brush head assembly 20 to move, and the torsion spring 18 and the trapezoidal bracket 19 press the brush head assembly 20 against the filter bottom plate 12. The brush head assembly 20 first wets the sludge on the filter through the spray head 202, and then cleans it through the mud cleaning brush 201, and finally wipes it dry through the water absorbing part 203. In addition, the spray head 202 can be used to spray detergent. The mud cleaning brush 201 can easily remove the sludge on the filter bottom plate 12 by spraying detergent, and finally wipe the residual detergent or muddy water with the water absorbing part 203. At the same time, the trapezoidal bracket 19 installed on the connecting vertical plate 16 can be around the position of the pin 17. The brush head assembly 20 is rotated, so the brush head assembly 20 can be directed toward the top mud pressing roller to clean the internal forming groove A7, and can also be directed downward to clean the gaps between the filter bottom plates 12. As the mud cleaning brush 201 has a certain length and flexibility, when the brush head assembly 20 contacts the sludge, it will be inserted into the sludge layer. For thicker sludge accumulation areas, such as the thick sludge layer accumulated for a long time at the bottom of the sewage sedimentation tank, the rotation or vibration action of the brush head assembly 20 will produce a stirring effect in the sludge, which not only helps to loosen the sludge, but also fully exposes the internal sludge components, avoiding the situation where only the surface sludge is cleaned while a large amount of sludge still remains inside.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
