DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 , Figure 2As shown, a movable integrated suction and discharge scum processing device includes a shell 1, the shell 1 is provided with an air outlet 22, a negative pressure fan 11 is provided at the air outlet 22, the shell 1 is connected to a retractable hose 4, and the end of the hose 4 is connected to a probe 2 through a fixed tube 3; a screw conveying press 13 is provided in the shell 1, the input end of the screw conveying press 13 is located below the connection between the shell 1 and the hose 4, a discharge pipe 14 is provided on the shell 1, and the discharge pipe 14 is connected to the output end of the screw conveying press 13, a liquid collecting tank 15 is provided below the screw conveying press 13, an external discharge pipe 17 is provided at the bottom of the liquid collecting tank 15, the external discharge pipe 17 runs through the bottom of the shell 1, and a valve 16 is provided on the external discharge pipe 17.

[0020] A bracket 6 is provided on the housing 1 , and the hose 4 is mounted on the bracket 6 .

[0021] A hydraulic expansion and contraction device 5 is provided between the fixed pipe 3 and the housing 1 .

[0022] The air outlet 22 is located at the top of the housing 1 , and an air filter device 10 is provided below the air outlet 22 .

[0023] A centrifugal separator 9 is provided below the air filter device 10 , and the centrifugal separator 9 is connected to the top of the housing 1 via a spring oscillator 12 .

[0024] A side baffle 7 and a drop plate 8 are provided below the centrifugal separator 9. The side baffle 7 is tilted at the connection between the hose 4 and the shell 1. The drop plate 8 is located below the side baffle 7 and in the opposite direction of the tilt direction of the side baffle 7. The lower end of the drop plate 8 leads to the input end of the screw conveying press 13.

[0025] The housing 1 is provided with a ladder 20. The housing 1 is provided with an inspection port 21.

[0026] An electric control box 19 is provided on the housing 1 , and the electric control box 19 is connected to the negative pressure fan 11 , the hydraulic expansion and contraction device 5 , the centrifugal separator 9 , the screw conveying press 13 , and the spring oscillator 12 .

[0027] A universal wheel 18 is provided at the bottom of the housing 1 .

[0028] The negative pressure fan 11 is turned on, and the scum is sucked into the fixed pipe 3 through the probe 2 in the form of negative pressure and then enters the hose 4. The position of the probe 2 can be moved and adjusted by the hydraulic telescopic device to serve a larger area.

[0029] After the scum enters the housing 1, the first step of solid-liquid-gas separation is carried out through the side baffle 7. A part of the solid and liquid directly enters the scum pressing device 13 below, and a part of the solid and liquid falls on the slide plate 8 and slides down to enter the scum pressing device 13 below. The solid and liquid are separated by the screw conveyor press 13, and the solid waste is discharged from the discharge pipe 14. The liquid generated during the screw extrusion process is collected in the liquid collection tank 15 and then discharged through the external discharge pipe 17. After the gas separated by the side baffle 7 enters the centrifugal separator 9 upward for the second step of solid-liquid-gas separation, the gas is filtered by the air filter 10 and discharged from the air outlet 22, and the solid and liquid enter the scum pressing device 13.

[0030] A spring oscillator 12 is connected to the upper part of the centrifugal separator 9 to perform oscillation dust removal when the device is not in use.

[0031] The electric control box 19 can operate and control the negative pressure fan 11 , the hydraulic expansion device 5 , the centrifugal separator 9 , the screw conveying press 13 , and the spring oscillator 12 .

[0032] The device of the utility model can be applied to the situation where scum is enriched on the surface of the water pool, which is generally common in biological pools, secondary sedimentation tanks, high-efficiency sedimentation tanks and other pools in urban sewage and industrial wastewater treatment plants. The operation and management are more efficient and the degree of automation is high.

[0033] The utility model optimizes and improves the traditional scum collection function, solves the problem that the scum is discharged from the tank body and then circulated in the system. The utility model can collect and compress the scum in one step. The whole plant only needs to be equipped with one utility model device, and there is no need to set up scum skimming pipes at the end of each sedimentation tank, the anaerobic zone of the biological pool, and the anoxic zone, which not only saves civil engineering and investment, but also avoids the risk that the scum skimming pipe cannot effectively remove scum due to water level fluctuations.
