Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a municipal sludge treatment device. Background Art

[0002] Sludge is generated during the operation and maintenance of urban facilities related to urban life and urban life activities. According to the source, it can be divided into sewage treatment plant sludge, water supply plant sludge, drainage pipe sludge, dredging sludge and construction mud. The properties of sludge from different sources vary greatly, and the corresponding treatment and disposal technical requirements and resource utilization methods are also different.

[0003] However, the existing municipal sludge treatment device needs to be dehydrated after the crushing and mixing is completed, but the existing treatment device does not carry a dehydration device, which causes inconvenience to the staff.

[0004] In the prior art, a Chinese patent with a publication number of CN213266199U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A municipal sludge treatment device includes a box body, a support column is arranged at the bottom of the box body, a feed port is arranged at the top of the box body, a motor is arranged at one side of the box body, a first rotating shaft is installed at the output end of the motor, a first crushing knife is arranged on the surface of the first rotating shaft, a first gear is arranged at one end of the first rotating shaft, a second rotating shaft is passed through the surface of the box body, and a second crushing knife is arranged on the surface of the second rotating shaft. By arranging a guide pipe at the bottom of the box body, after the sludge is crushed and stirred, it can be directly introduced into the cement separation box, and by arranging a cement separation box at one end of the guide pipe, the sludge is squeezed by a hydraulic cylinder, a hydraulic rod and an extrusion plate, and the water contained in the sludge is discharged from the cement separation box through the water outlet, and the remaining sludge is discharged from the cement separation box through the discharge port, which is convenient for the use of this device.

[0005] Although the prior art can squeeze the sludge through the hydraulic cylinder, the hydraulic rod and the squeezing plate, and discharge the water contained in the sludge from the cement separation box through the water outlet, the squeezing plates are arranged end to end in a V-shape in the cement separation box, so the sludge falling between the squeezing plates is difficult to be quickly discharged from the cement separation box after the water is squeezed out, which affects the progress of the subsequent cement separation work.

[0027] The present invention is further described in detail below in conjunction with the embodiments:

[0028] Example 1

[0029] like Figure 1-5 As shown, the utility model provides a municipal sludge treatment device, including a cement separation box 1, the bottom of the inner wall of the cement separation box 1 is fixedly connected with an arc-shaped filter press plate 2, and an arc-shaped pressure plate 6 is arranged inside the arc-shaped filter press plate 2.

[0030] The two sides of the arc-shaped pressing plate 6 are fixedly connected with the sealing frame edge 14, and the sludge is transported to the cement separation box 1 through the sewage inlet pipe 3. At this time, the sludge is located on the inner wall of the arc-shaped filter press plate 2. Then, the power is turned on to start the hydraulic rod 7, so that the hydraulic rod 7 pushes the arc-shaped pressing plate 6 downward. During the downward movement of the arc-shaped pressing plate 6, the sealing frame edge 14 will be driven downward. The two ends of the arc-shaped pressing plate 6 will fit with the inner walls of the two ends of the cement separation box 1, and the sealing frame edge 14 will close the gap between the two sides of the arc-shaped pressing plate 6 and the cement separation box 1. The inner wall of the arc-shaped filter press plate 2 is movably connected with an arc-shaped scraper plate 9, one end of which is threadedly connected to a threaded rod 11 through a threaded ring, and the other end of the arc-shaped scraper plate 9 is slidably connected to a guide slide rod 10 through a collar.

[0031] A hydraulic rod 7 is fixedly connected to the bottom of the inner wall of the arc-shaped pressing plate 6 , a support frame 8 is fixedly connected to the top of the hydraulic rod 7 , and a drainage pipe 15 is fixedly connected to the bottom of the cement separation box 1 .

[0032] One end of the threaded rod 11 is meshed with a driving motor 12 through a gear. The arc-shaped pressing plate 6 has no contact with the inner wall of the arc-shaped filter press plate 2. A scraper plate adapting groove 13 is provided at one end of the arc-shaped filter press plate 2.

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the outer walls at both ends of the threaded rod 11 are fixedly connected to the outer wall of the cement separation box 1 through an axle seat, and the two ends of the guide slide rod 10 are fixedly connected to the outer wall of the cement separation box 1 through a mounting seat.

[0035] The bottom end of the support frame 8 is fixedly connected to one side of the cement separation box 1 .

[0036] The outer wall of the driving motor 12 is fixedly connected to the outer wall of the cement separation box 1 .

[0037] Both ends of the cement separation box 1 are fixedly connected with a slag discharge pipe 4 , and one end of the cement separation box 1 is fixedly connected with a sewage inlet pipe 3 .

[0038] The bottom surface of the cement separation box 1 is fixedly connected with a supporting leg 5 .

[0039] The following is a detailed description of the working principle of the municipal sludge treatment device.

[0040] like Figure 1-5As shown, when in use, the sludge is transported to the cement separation box 1 through the sewage inlet pipe 3. At this time, the sludge is located on the inner wall of the arc filter press plate 2. Then, the power is turned on to start the hydraulic rod 7, so that the hydraulic rod 7 pushes the arc pressure plate 6 to move downward. During the downward movement of the arc pressure plate 6, the sealing frame edge 14 will be driven downward. The two ends of the arc pressure plate 6 will fit with the inner walls of the two ends of the cement separation box 1, and the sealing frame edge 14 will seal the gap between the two sides of the arc pressure plate 6 and the cement separation box 1.

[0041] As the arc pressure plate 6 continues to move downward, the sludge will be squeezed, and the squeezed water will be discharged from the cement separation box 1 through the drain pipe 15. When the squeezing work is completed, the hydraulic rod 7 drives the arc pressure plate 6 to move upward, and the drive motor 12 is started at this time. The drive motor 12 drives the threaded rod 11 to rotate through the gear, and the threaded rod 11 drives the arc scraper plate 9 to move toward the slag discharge pipe 4 through the outer wall thread, and the remaining soil is pushed into the slag discharge pipe 4 and discharged out of the cement separation box 1. When the arc scraper plate 9 moves to one side of the cement separation box 1, the drive motor 12 is adjusted to drive the threaded rod 11 to rotate in the opposite direction. At this time, the arc scraper plate 9 begins to reset and scrape in the inner wall of the arc filter press plate 2, and the remaining soil is pushed to the slag discharge pipe 4 at the other end of the cement separation box 1 for collection and discharge, thereby completing the mud and water separation work.

[0042] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the utility model. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
