Description

A high-efficiency municipal sludge treatment system

technical field

The invention relates to the technical field of municipal engineering, in particular to an efficient municipal sludge treatment system.

Background technique

Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity (outside the red line), telecommunications, heat, gas, etc. The municipal pipe network in the prior art is often blocked due to the sludge mixed liquid flow, wherein the sludge mixed liquid flow mainly includes the following parts: waste plastic bags, foam and other plastic garbage with a certain volume; scrap metal or metal residues and other small Granular waste metal waste; and sludge and wastewater, etc.

The municipal pipe network in the prior art is often equipped with a filter for filtering, but the conventional filter has a simple design and structure, and the use effect is not good. Among them, waste plastic bags and foams can easily cause the filter to be blocked, resulting in the breakdown of the municipal pipe network. The circulation is not smooth, and the municipal staff in the prior art cannot clean the filter screen reasonably and efficiently, which is time-consuming and laborious, very troublesome, and seriously affects the smooth operation of the municipal pipe network. Furthermore, the waste metals in the municipal sludge mixed flow in the prior art cannot be separated and screened reasonably and effectively, and are easy to accumulate with the sludge on the pipeline. If it cannot be cleaned in time, as time goes by, the waste metal will corrode with the municipal metal pipes, and it will be very difficult to clean up at this time. This will not only occupy the drainage area of the municipal pipes, but also speed up the construction of the municipal pipe network. The degree of damage is very unfavorable to the maintenance work of the municipal pipe network.

At the same time, the existing municipal engineering sludge treatment structure is relatively simple, not automatic enough, time-consuming and labor-intensive, and the degree of intelligence is low, the period of sludge treatment is long, and the separation effect is not good. That is to say, it is impossible to complete the centralized removal of different types of garbage on the basis of screening the types of garbage, as well as the efficient and intelligent separation of sludge and water. The treated sludge can be recycled and reused in other fields, and the purified water can be used again for spraying municipal roads or watering municipal landscape plants. However, the municipal sludge treatment in the prior art is relatively simple. As far as the sludge is concerned, it is not pure enough, and as far as the water flow is concerned, the cleanliness is not enough, its recycling value is not high, and the treatment cost is greatly increased. However, the flocculants in the prior art have been tested and shown to perform well in the separation of mixed sludge and water. Therefore, we need a high-efficiency municipal sludge treatment system.

The working process of an efficient municipal sludge treatment system:

First, the staff opens the on-off valve on the liquid inlet pipe, and the sludge mixed flow in the municipal pipeline will enter the cavity of the tank. When the sludge mixed flow passes through the filter screen, it mainly filters and isolates garbage such as plastic bags with a certain volume, and small particles such as sludge can pass through naturally. In the initial state, the compression spring is at full length, and the filter screen is at the far left. When the sludge mixed liquid flow enters and the filter screen is not blocked, the filter screen will move to the right by a certain small distance, which can be ignored. Furthermore, by initially adjusting the distance between the trigger switch and the frame, the amount of garbage such as plastics carried by the filter net is correspondingly adjusted. Specifically, the closer the trigger switch is set to the frame, the smaller the amount of plastic waste carried by the filter will be blocked.

When the amount of plastic waste carried by the filter screen increases, more and more mesh holes are blocked, and the grid frame will continue to move to the right until the trigger switch is squeezed, and the trigger switch transmits a start signal to the drive motor. The drive motor rotates forward, which drives the drive screw to rotate clockwise, and then drives the gathering plate to move. During the process of moving the gathering plate, the garbage such as plastics is mainly processed in a centralized manner, and the cleaning and cleaning of the filter net are also completed synchronously. Mesh through. In the next step, the electro-hydraulic push rod is activated and gradually extended. Under the auxiliary pushing action of the push plate, the plastic and other garbage concentrated on the gathering plate will be pushed into the discharge port, and then centralized treatment and discharge through the sewage pipe.

After completing the separation of garbage with a certain volume such as plastics, the sludge mixed liquid flow not only realizes the full contact between the rotating blades and the sludge mixed liquid during the clockwise rotation of the rotating motor, but also completes the adsorption and separation of waste metals. At the same time, it is also beneficial to the transportation of the next step of the sludge mixed liquid flow. In the next step, the sludge mixture after metal separation flows from the connecting pipe into the mud cleaning chamber. During this process, the secondary filtration of impurities such as intermediate particles is completed through the screen.

When the weighing sensor detects that the weight of the mixed mud flow in the mud cleaning chamber reaches a preset value, the electromagnetic switching valve on the connecting pipe is closed. The purpose of such setting is to facilitate the control of the weight of the mixed sludge flow, and then match the added amount of a certain weight of flocculant through a preset ratio. Among them, the amount of flocculant added can be used as a reference according to the start-up time of the micro liquid pump. The micro liquid pump is started, and a certain amount of flocculant is added into the sludge mixed liquid flow. The next step is to start the extension of the hydraulic lifting rod, and then drive the main shaft and the stirring rod to penetrate into the mud-liquid mixed flow as a whole, start the stirring motor, and then drive the main shaft and the stirring rod to rotate synchronously, so as to realize the comprehensive mixing of the sludge mixed liquid flow and flocculant Stirring speeds up the uniform mixing of the flocculant and the sludge mixed liquid, thereby improving the time and efficiency of the mud and liquid stratification. The mixing time is kept for 8-10 minutes, and then the hydraulic lifting rod is raised to drive the main shaft and other structures to rise. The main function is to avoid movement interference in the mud cleaning operation.

In the next step, the mud-liquid mixed flow is left to stand for 20-30 minutes, and then the stratified water is drained from the liquid outlet pipe through the pump, and further filtered and purified through the purification unit to prevent sludge from entering, and then centralized recycling and reuse. In the normal state, the electromagnetic switch valve on the liquid outlet pipe remains closed, and opens in the liquid discharge state. After the drainage operation is completed, start the hydraulic cylinder, and the hydraulic cylinder will drive the extension of the driving arm to drive the mud cleaning plate to carry out the sludge pushing operation, so that the cycle is operated until the sludge is completely discharged from the sludge discharge pipe. In the initial state, the electromagnetic switch valve on the mud discharge pipe remains closed, and opens in the mud discharge state.
