Description

Technical Field

[0001] The utility model relates to the technical field of siphon type mud-water separation and sludge concentration systems, in particular to a siphon type mud-water separation and sludge concentration system. Background Art

[0002] With my country's increasing emphasis on environmental pollution, the construction of local sewage treatment facilities is increasing, inevitably leading to a corresponding increase in sludge generation within water treatment systems. This has led to an increasingly prominent disposal problem, demanding urgent solutions. Municipal sewage treatment plants, small sewage treatment plants, and industrial enterprises are experiencing high sludge discharge, untimely sludge discharge, poor sludge concentration, and high moisture content in dewatered sludge. These issues are causing pipe blockages in some treatment units, the appearance of large amounts of floating sludge on the water surface, poor effluent quality, high equipment loads, and high chemical consumption.

[0003] Existing sludge thickening systems include gravity, centrifugal, flotation, and belt thickening. Each sludge thickening unit has its own advantages and disadvantages, but the sludge thickening effect is poor, the chemical consumption is high, and the equipment operating load is high, resulting in high sludge treatment operating costs. Currently, the most commonly used thickening system is the gravity sludge thickening tank. However, in actual operation, the sludge has a high moisture content and the supernatant is not completely discharged. This results in increased chemical dosage in the desludging system and a high moisture content in the sludge cake. Therefore, it is urgent to design a siphon-type mud-water separation sludge thickening system to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a siphon-type mud-water separation sludge thickening system to solve the problem mentioned in the background art that the existing sludge thickening systems are composed of gravity, centrifugal, flotation and belt thickening units. Each sludge thickening unit has its own advantages and disadvantages, but the sludge thickening effect is poor, the chemical consumption is high, the equipment operating load is high, resulting in high sludge treatment operating costs. The commonly used thickening system is the gravity sludge thickening tank, but in actual operation, there are problems such as high water content of the mud output and incomplete discharge of the supernatant, which leads to increased dosage of chemicals in the desludging system and high water content of the mud cake.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a siphon-type mud-water separation sludge thickening system, comprising: a thickening tank, a siphon mechanism is provided inside the thickening tank, a cleaning mechanism is provided inside the thickening tank, the siphon mechanism includes a mixed liquid feed port, the mixed liquid feed port is fixedly provided at the front end of the thickening tank, a sludge discharge port is provided on the outer wall of the thickening tank, a porous collection flower tube is provided inside the thickening tank, a siphon branch pipe is inserted into the porous collection flower tube, the upper end of the siphon branch pipe is connected to a siphon tube, the end of the siphon tube away from the siphon branch pipe is provided with a supernatant siphon discharge port, and the siphon tube is provided with a water injection port and an overflow port.

[0006] Preferably, one end of the sludge discharge port provided inside the concentration tank is connected to an inclined pipe, and the inclined pipe is provided in an inclined shape.

[0007] Preferably, a support column is fixedly connected to the bottom end of the concentration tank, and an anti-slip seat is provided at the bottom end of the support column.

[0008] Preferably, the cleaning mechanism includes a porous flower tube brush, which is sleeved on the outside of the porous collecting flower tube. The porous flower tube brush is arranged in a circular ring shape, and a cleaning brush is arranged on the inner wall of the porous flower tube brush.

[0009] Preferably, a lifting handle is fixedly connected to the upper end of the porous flower tube brush, and the lifting handle can be raised and lowered inside the concentration tank.

[0010] Preferably, the outer wall of the porous flower tube brush is fixedly connected to a limiting block, and the limiting block is clamped at the upper end of the concentration tank.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The siphon type mud-water separation sludge thickening system is provided with a siphon mechanism. When the siphon type mud-water separation sludge thickening system is used, after the mixed liquid enters the thickening tank from the mixed liquid feed port, under the action of its own weight, the water in the gaps between the lower particles is squeezed out of the interface by the settled upper particles, and the particles become denser. Through the action of squeezing, the sludge is continuously settled and concentrated, thereby increasing the sludge concentration, eliminating the overflow of the supernatant and entering the porous collection tube to achieve sludge concentration. At the same time, clean water is injected into the water inlet at the initial stage of system operation or when the pipeline is replaced until clean water flows out of the overflow port, close the overflow port valve, and open the bottom supernatant siphon. The discharge outlet realizes siphoning, and the supernatant siphon outlet is opened to achieve the siphoning purpose of the siphon pipe and the siphon branch pipe, and the supernatant is continuously discharged from the supernatant siphon outlet, and the concentrated sludge at the bottom is transported to the sludge dewatering machine through the sludge discharge port for dehydration, so that the whole system can achieve the purpose of high efficiency, energy saving and continuous operation. Through this design, the siphon type mud-water separation sludge thickening system can realize rapid, efficient and continuous enrichment of sludge in a short time. On the one hand, the sludge concentration in the thickening tank can be high and the water content can be low. On the other hand, the dosage of the dehydrator can be reduced, the water content of the dehydrated sludge can be reduced, and at the same time, the transportation cost and disposal cost can be reduced, thereby improving the practicality and efficiency of the device.

[0013] 2. The siphon-type mud-water separation and sludge thickening system is provided with a cleaning mechanism. When the siphon-type mud-water separation and sludge thickening system is used, the sludge sinks and concentrates under the action of its own weight, and the supernatant enters the porous collection tube. After the system has been running for a period of time, the porous collection tube is blocked. The lifting handle can be used to drive the porous tube brush to move up and down to remove the sludge adhered to the outer wall of the pipe, thereby improving the fluidity of the porous collection tube. Through this design, the siphon-type mud-water separation and sludge thickening system can clean the sludge adhered to the outer wall of the porous collection tube, thereby improving the fluidity of the porous tube and improving the practicality and cleanliness of the device.

Through the action of squeezing, the sludge is continuously settled and concentrated, thereby increasing the sludge concentration, eliminating the overflow of the supernatant and entering the porous collection flower tube 213 to achieve sludge concentration. At the same time, clean water is injected into the water inlet 217 at the initial stage of system operation or when the pipeline is replaced until clean water flows out of the overflow port 218, the overflow port 218 valve is closed, and the bottom supernatant siphon outlet 216 is opened to achieve siphoning. The supernatant siphon outlet 216 is opened to achieve the siphoning purpose of the siphon pipe 215 and the siphon branch pipe 214, and the supernatant is continuously discharged from the supernatant siphon outlet 216. The lower concentrated sludge is transported to the sludge dewatering machine through the sludge discharge port 212 for dehydration, so that the entire system can achieve the purpose of high efficiency, energy saving and continuous operation.

[0022] Furthermore, one end of the sludge discharge port 212 disposed inside the concentration tank 111 is connected to an inclined pipe 219 , and the inclined pipe 219 is disposed in an inclined shape.

[0023] Furthermore, a support column 220 is fixedly connected to the bottom end of the concentration tank 111 , and an anti-slip seat 221 is provided at the bottom end of the support column 220 .

The porous flower tube brush 311 is arranged in a circular shape, and a cleaning brush is provided on the inner wall of the porous flower tube brush 311. Through this design, when the siphon-type mud-water separation sludge concentration system is used, the sludge sinks and concentrates under the action of its own weight, and the supernatant enters the porous collecting flower tube 213. After the system has been running for a period of time, the porous collecting flower tube 213 is blocked.

[0027] Working principle:

[0028] When using the siphon type mud-water separation sludge thickening system, after the mixed liquid enters the thickening tank 111 from the mixed liquid feed port 211, the water in the gaps between the lower particles is squeezed out of the interface by the settled upper particles under the action of its own weight, and the particles become denser. Through the action of squeezing, the sludge is continuously settled and concentrated, thereby increasing the sludge concentration, eliminating the overflow of the supernatant and entering the porous collection flower tube 213 to achieve sludge concentration, and at the same time, clean water is injected into the water injection port 217 to run the system. In the initial stage or when replacing the pipeline, it is necessary to inject until clean water flows out of the overflow port 218, close the overflow port 218 valve, open the bottom supernatant siphon outlet 216 to realize siphoning, open the supernatant siphon outlet 216 to achieve the siphoning purpose of the siphon pipe 215 and the siphon branch pipe 214, and continuously discharge the supernatant from the supernatant siphon outlet 216. The concentrated sludge at the bottom is transported to the sludge dewatering machine through the sludge discharge port 212 for dehydration, so that the entire system can achieve the purpose of high efficiency, energy saving and continuous operation.

[0029] When using the siphon-type mud-water separation sludge concentration system, the sludge sinks and concentrates under the action of its own weight, and the supernatant enters the porous collection tube 213. After the system has been running for a period of time, the porous collection tube 213 is blocked. The lifting handle 312 can be used to drive the porous tube brush 311 to move up and down to remove the sludge adhered to the outer wall of the pipe, thereby improving the fluidity of the porous collection tube 213.
