Technical Field
The utility model relates to the technical field of sewage treatment equipment, in particular to a system for automatically cleaning a filter pressing pipeline.
Background
The existing sludge press filtration system of the sewage treatment system is that sludge in a sludge concentration tank is conveyed to a press filter through two pneumatic pumps (one is used for one) and then water in the sludge is press-filtered out by the press filter. Generally, the sludge in the system is deposited in the pipeline after the previous use and is weakly alkaline after the 3 days of use, and the sludge is hardened and scaled in the pipeline to block the pipeline for a long time, so that the sludge cannot be used normally, and the pipeline and equipment are removed for cleaning every three months basically, so that a large amount of manpower and material resources are consumed, and the normal production is influenced.

In the above figures: 1. a sludge concentration tank; 2. a first pneumatic valve; 3. a pneumatic pump; 4. a plate and frame filter press; 5. a cleaning liquid stock solution tank; 6. a second pneumatic valve; 7. a check valve.
Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1, in order to solve the problems of sludge precipitation and scale formation on the inner wall of a sludge conveying pipeline after intermittent use. The utility model provides a system for automatically cleaning filter pressing pipelines, which comprises a sludge concentration tank 1, a first pneumatic valve 2, a pneumatic pump 3 and a plate-and-frame filter press 4 which are sequentially connected through a sludge conveying pipeline, wherein the input end of the pneumatic pump 3 is connected with a cleaning pipeline in parallel, the cleaning pipeline is sequentially connected with a cleaning liquid raw liquid pool 5 and a second pneumatic valve 6, the first pneumatic valve 2, the second pneumatic valve 6 and the pneumatic pump 3 are controlled in a linkage manner, and after the first pneumatic valve 2 is closed, the second pneumatic valve 6 is automatically opened.
A cleaning solution raw liquid pool 5 with two cubic meters of volume is arranged, weak acid cleaning solution prepared by clean water is contained in the cleaning solution raw liquid pool 5, the weak acid cleaning solution is connected to an inlet pipe of a pneumatic pump 3 through a DN65 pipeline, and a second pneumatic valve 6 and a check valve 7 are arranged on the pipeline; after the first pneumatic valve 2 and the pneumatic pump 3 are opened, the sludge in the sludge concentration tank 1 is conveyed to the plate-and-frame filter press 4 through a sludge conveying pipeline, and after the sludge in the sludge concentration tank 1 is conveyed, the first pneumatic valve 2 is closed, and the plate-and-frame filter press 4 starts to work; when the first pneumatic valve 2 is closed, the second pneumatic valve 6 is opened, the cleaning agent is conveyed into the sludge conveying pipeline, the pneumatic pump 3 and the plate-and-frame filter press 4 are cleaned, most of sludge in the sludge conveying pipeline is washed into the plate-and-frame filter press 4, after the second pneumatic valve 6 is opened for five minutes, the pneumatic pump 3 is closed, and as the pneumatic pump 3 is closed, the second pneumatic valve 6 is closed, and the cleaning process is finished.
Because the cleaning liquid is weakly acidic, even if a small amount of sludge remains in the sludge conveying pipeline, the condition that the sludge conveying pipeline is blocked by hardening and scaling after being diluted and soaked by the cleaning liquid is avoided, so that the condition that the filter pressing pipeline system is blocked every three months when the filter pressing pipeline system is used is solved, and the pipeline cleaning is required to be disassembled.
As shown in fig. 1. Two sludge conveying pipelines are connected in parallel between the first pneumatic valve 2 and the plate-and-frame filter press 4, and each sludge conveying pipeline is provided with a pneumatic pump 3. When the filter pressing pipeline system is not used for a long time and the cleaning liquid with enough volume is not prepared in the cleaning liquid raw liquid pool 5, the stop valves between the sludge conveying pipeline and the sludge concentration tank 1, the cleaning liquid raw liquid pool 5 and the plate-and-frame filter press 4 are closed, and a pneumatic pump 3 is started, so that liquid in the sludge conveying pipeline flows between two parallel sludge conveying pipelines, and the occurrence of precipitation is further reduced. In addition, all install pneumatic pump 3 on two mud transfer pipelines, two pneumatic pumps 3 have guaranteed that inside the mud transfer pipeline has sufficient power, guarantee the stable transportation of mud, avoid taking place the condition of jam because of lacking power.
As shown in fig. 1, in order to prevent the backflow of the sludge, the sludge is poured into the cleaning liquid stock tank 5. A check valve 7 is arranged between the cleaning solution raw liquid pool 5 and the second pneumatic valve 6.
As a preferred embodiment of the present utility model. The cleaning solution raw liquid tank 5 contains an acidic cleaning solution.
