Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an anaerobic tank for municipal sewage treatment. Background Art

[0002] Anaerobic biological treatment technology is a highly efficient sewage treatment method in which the organic matter in sewage is decomposed, metabolized and digested by anaerobic bacteria under anaerobic conditions, which greatly reduces the organic matter content in sewage and produces biogas at the same time. In the process of municipal sewage treatment, municipal sewage is usually discharged into an anaerobic tank. Under anaerobic conditions, anaerobic bacteria decompose the organic matter in the sewage, thereby achieving municipal sewage treatment.

[0003] However, the existing anaerobic tanks for municipal sewage treatment have the following main drawbacks during use: as the treatment proceeds, more and more sludge accumulates at the bottom of the anaerobic tank, resulting in a poor sewage treatment effect, which requires regular cleaning. However, under the existing technology, it is necessary to manually detect the thickness of the sludge in the anaerobic tank and determine whether the anaerobic tank should be cleaned based on the sludge thickness. In addition, sludge cleaning is troublesome, time-consuming and labor-intensive. Therefore, there is room for improvement. Utility Model Content

When the sludge in the semicircular shell needs to be cleaned, the moving piece is started and the delivery piece is opened. At this time, the moving piece drives the cleaning column to move in the semicircular shell, and the sludge accumulated in the semicircular shell is pushed out through the delivery piece, so as to realize the cleaning of the sludge. The utility model has a simple structure, is easy to use, and has a high sludge cleaning efficiency.

At this time, the laser rangefinder detects the distance between the bottom wall of the cylinder and the top of the detection member. When the distance is greater than the set value, it is judged that the sludge thickness is normal. When the distance is less than the set value, it is judged that the sludge thickness is too thick. At this time, the moving member and the delivery member are started to clean the sludge. Through the above arrangement, the sludge thickness can be automatically detected and cleaned, which further increases the practical performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] Combination Figure 1-4 As shown, this embodiment provides an anaerobic tank for municipal sewage treatment, including: a main module 100 and a measurement module 200.

[0027] Among them, the main module 100 includes a pool body 110, a semicircular shell 120 fixed on one side of the pool body 110 and connected to the inner cavity of the pool body 110, a cleaning column 130 with one end embedded in the circular plate shell and the other end extending out of the semicircular shell 120, a delivery piece 140 installed on one side of the semicircular shell 120, and a moving piece 150 installed on the top of the semicircular shell 120 and fixedly connected to one end of the cleaning column 130.

[0028] The tank body 110 is used to store municipal sewage that needs to be anaerobically treated. The semicircular shell 120 is connected to the inner cavity of the tank body 110 for sludge to enter. The inner bottom wall of the tank body 110 is inclined, and the inclined surface faces the direction of the semicircular shell 120, so that the sludge in the tank body 110 can enter the semicircular shell 120 along the inclined surface.

[0029] One end of the cleaning column 130 extends into the semicircular shell 120 , and the other end is located outside the semicircular shell 120 , and is used to push the sludge in the semicircular shell 120 into the delivery member 140 under the drive of the moving member 150 .

[0030] The delivery member 140 is used to deliver the sludge, and includes a sewage pipe 141 installed at one end of the semicircular shell 120 and connected to the inner cavity of the semicircular shell 120, and an electric valve 142 installed on the sewage pipe 141. The sewage pipe 141 is used to discharge the sludge, and the electric valve 142 is used to control the opening and closing of the sewage pipe 141.

[0031] The moving part 150 is used to drive the cleaning column 130 to move, and includes a first electric telescopic rod 151 fixed to the top of the semicircular shell 120 and a pull plate 152 whose one end is fixed to the end of the first electric telescopic rod 151 and the other end is fixedly connected to the end of the cleaning column 130. When the first electric telescopic rod 151 moves, the cleaning column 130 can be driven to move synchronously through the pull plate 152.

[0032] The measuring module 200 is used to detect the thickness of the sludge, and includes a bottom plate 210 fixed at the top of the tank body 110, a cylinder 220 fixed at the top of the bottom plate 210, a detection component 230 movably arranged in the inner cavity of the cylinder 220 and extending through the bottom plate 210, a laser rangefinder 240 installed at the top of the cylinder 220 and extending into the inner cavity of the cylinder 220, and a lifting component 250 installed on one side of the tank body 110.

[0033] The bottom plate 210 is used to install the cylinder 220, and the cylinder 220 is used to install other components. The detection member 230 includes a support rod 231 movably arranged in the inner cavity of the cylinder 220 and the end of which passes through the bottom plate 210 and extends into the inner cavity of the pool body 110, and a counterweight plate 232 fixed to the bottom end of the support rod 231. When the support rod 231 loses the limit of the lifting member 250, the support rod 231 is driven to fall under the action of the counterweight plate 232, and stops moving when the counterweight plate 232 contacts the top of the sludge. At this time, the distance sensor can detect the distance between the top of the support rod 231 and the inner top wall of the cylinder 220. When the distance is greater than the set value, it is judged that the sludge thickness is normal. When the distance is less than the set value, it is judged that the sludge thickness is too thick. At this time, the moving member 150 and the sending member 140 are started to clean the sludge.

[0034] The lifting member 250 is used to drive the detection member 230 to reset, and includes a second electric telescopic rod 251 fixed to one side of the pool body 110 and a support plate 252 fixed to the top of the second electric telescopic rod 251. A protrusion 2311 extending out of the cylinder 220 is fixed to one side of the top of the support rod 231, and the end of the support plate 252 is located below the protrusion 2311, so that when the second electric telescopic rod 251 moves upward, it can drive the support plate 252 to move upward, and the upward movement of the support plate 252 drives the protrusion 2311 to move upward, that is, drives the support rod 231 and the counterweight plate 232 to move upward and reset.

[0035] A through hole is formed on the outer surface of the cylinder 220, and the protrusion 2311 is inserted into the through hole and moves, thereby ensuring the stability of the support rod 231 when moving.

[0036] The working principle and use process of the utility model are as follows: when in use, the second electric telescopic rod 251 drives the support plate 252 to retract, at which time the protrusion 2311 loses its limit, that is, the support rod 231 loses its limit, and under the action of the counterweight plate 232, the support rod 231 is driven to fall, and when the counterweight plate 232 contacts the top of the sludge, it stops moving. At this time, the laser rangefinder 240 detects the distance between the top wall of the cylinder 220 and the top of the support rod 231. When the distance is greater than the set value, it is judged that the sludge thickness is normal. At this time, the second electric telescopic rod 251 is started, driving the support plate 252 to move up Reset, the support plate 252 moves up and resets, driving the protrusion 2311 to move, that is, driving the support rod 231 and the counterweight plate 232 to reset, which is convenient for downward movement detection. When the distance is less than the set value, it is judged that the sludge thickness is too thick. At this time, the moving part 150 and the sending part 140 are started, and the first electric telescopic rod 151 is retracted. The cleaning column 130 is driven to move in the semicircular shell 120 through the pulling plate 152, and the sludge in the semicircular shell 120 is pushed to the sewage pipe 141. At the same time, the electric valve 142 is opened to send the sludge through the sewage pipe 141 to complete the sludge discharge operation.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
