Abstract
The utility model relates to a biochemical pond excess sludge pump exhaust apparatus of CASS, including being located the biochemical pond outer and the stealthily dirty pump that the input is connected with biochemical pond lower part, the output of stealthily dirty pump has connected gradually telescopic joint, check valve and maintenance valve, the output of maintenance valve is connected with the mud pipe, and the other blast pipe that has connect on the pipeline that is located telescopic joint and stealthily between the dirty pump, be provided with the solenoid valve on the blast pipe, the output of blast pipe is linked together with the upper portion in biochemical pond. The device can effectively avoid the submersible sewage pump to suck air to cause the phenomenon of air-bound and unable liquid suction, and improves the sludge discharge efficiency.
Description
Technical Field
The utility model relates to a CASS biochemical pond excess sludge pump exhaust apparatus.
Background
The CASS process excess sludge is discharged by a submersible sewage pump, the production process is basically discharged at the later stage of precipitation, the point position of the submersible sewage pump is arranged, the flowability of the precipitated sludge is poor, the influence of disturbance on the precipitation effect is avoided, the discharge amount per period is small, and the efficiency is low. For improving row's mud efficiency, increase the collection position with the mode of pipeline collection, will effectively improve row's mud efficiency, nevertheless the CASS technology adopts the mode of bottom aeration, and the sedimentation process is again behind the aeration flow, and the air is often inhaled row's mud pipeline, causes the centrifugal pump to have the air that the air can not the imbibition to tie up the phenomenon.
Disclosure of Invention
An object of the utility model is to provide a CASS biochemical pond excess sludge pump exhaust apparatus, the device can effectively avoid stealthily dirty pump suction air to cause the unable imbibition of gas-tie phenomenon, improves row's mud efficiency.
The technical scheme of the utility model lies in: the utility model provides a CASS biochemical pond excess sludge pump exhaust apparatus, is including being located the biochemical pond outside and the input and the stealthily dirty pump that the biochemical pond lower part is connected, the output of stealthily dirty pump has connected gradually telescopic joint, check valve and service valve, the output of service valve is connected with the mud pipe, and the other blast pipe that has connect on the pipeline that is located between telescopic joint and the stealthily dirty pump, be provided with the solenoid valve on the blast pipe, the output of blast pipe is linked together with the upper portion in biochemical pond.
Furthermore, the submersible sewage pump and the check valve are respectively connected with the ground through a fixed seat.
Furthermore, the air inlet end of the exhaust pipe is connected with the lower part of a pipeline between the expansion joint and the submersible sewage pump through a quick-connection joint.
Further, the exhaust pipe is a stainless steel pipe.
Compared with the prior art, the utility model has the advantages of it is following: the device has simple structure, can effectively avoid the air-bound phenomenon that the submersible sewage pump cannot absorb liquid due to air suction, improves the sludge discharge efficiency, and reduces the pressure and time for subsequent sludge concentration and treatment; the mode of discharging gas and liquid and returning the gas and liquid to the biochemical pool is used, so that the environmental pollution is avoided. The CASS production cycle time is shortened, and the total phosphorus removal effect is obviously improved; low transformation cost and simple and convenient maintenance.

Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to FIG. 1
The utility model provides a CASS biochemical pond excess sludge pump exhaust apparatus, is including being located biochemical pond 1 outside and the input is with biochemical pond lower part be connected stealthily dirty pump 2, the output of stealthily dirty pump has connected gradually telescopic joint 3, check valve 4 and maintenance valve 5, the output of maintenance valve is connected with sludge discharge pipe 6, and the other blast pipe 7 that has connect on the pipeline that is located between telescopic joint and the stealthily dirty pump, be provided with solenoid valve 8 on the blast pipe, the output of blast pipe is linked together with biochemical pond's upper portion to return the gas-liquid in the biochemical pond.
In this embodiment, in order to connect the submersible sewage pump and the check valve to the ground stably, the submersible sewage pump and the check valve are connected to the ground through the fixing seat 9.
In this embodiment, in order to facilitate the maintenance, and let the better biochemical pond of letting in of gas-liquid, the inlet end of blast pipe is connected through the pipeline lower part between quick-connect joint and the expansion joint and the stealthily dirty pump.
In this embodiment, in order to prevent the exhaust pipe from being corroded and to improve the service life, the exhaust pipe is made of a stainless steel pipe.
In the present embodiment, an operation electrical box for controlling the solenoid valve is also provided.
The control logic of the electromagnetic valve is as follows: gas and liquid are discharged, the electromagnetic valve is closed after stable sludge discharge, the sludge is prevented from continuously returning to the CASS pool to disturb supernatant, and the sludge is normally opened in other time periods; meanwhile, the automatic program can be linked with a flowmeter arranged on a pipeline to control the opening and closing of the electromagnetic valve, so that the phenomena of pump idling and cavitation are effectively avoided.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
