Description
Technical Field
The utility model relates to a sewage treatment field especially provides a device is used with backwash to play water of MBR membrane processing system.
Background
At present, China is in an accelerated development period of rural environment comprehensive remediation, wherein the problem of sewage discharge generated in daily life of villagers is particularly prominent, and the sewage discharge standard is increasingly strict, so in recent years, MBR (Membrane bioreactor) membrane processes are widely applied to rural areas and other small and medium-sized sewage treatment fields.
The biggest problem in the application of MBR membranes is the clogging and cleaning of the membrane, and therefore in addition to the suction pump, another pump is generally provided for the backwashing of the membrane. The water pump is the main component of the whole set of equipment cost, adds a water pump and its accessory parts, directly leads to the cost obviously to rise.
Disclosure of Invention
The utility model aims at providing a single pump linkage MBR membrane goes out water and recoil device with lower, convenient to use is reliable.
The technical solution of the utility model is that: the utility model provides a single pump linkage MBR membrane goes out water and recoil device, includes MBR membrane, water pump, water tank the parallelly connected first solenoid valve and the second solenoid valve that is equipped with of water pump entry the parallelly connected third solenoid valve and the fourth solenoid valve that is equipped with of water pump export, wherein first solenoid valve and third solenoid valve respectively with MBR membrane export is parallelly connected, second solenoid valve and fourth solenoid valve respectively with the water tank is parallelly connected.
Parallelly connected first solenoid valve and second solenoid valve at the water pump entry, parallelly connected third solenoid valve and fourth solenoid valve at the export, when the MBR membrane goes out water, first solenoid valve and fourth solenoid valve keep opening, second solenoid valve and third solenoid valve keep closing, it can pass through first solenoid valve to go out water, the water pump entry, the water pump export, the fourth solenoid valve is sent into in the water tank, when needs recoil, first solenoid valve and fourth solenoid valve keep closing, second solenoid valve and third solenoid valve keep opening, backwash water in the water tank passes through the water pump entry in order, the water pump export gets into the MBR membrane and carries out the recoil. Just so realize that the single pump linkage goes out water and recoil operation to the MBR membrane through four solenoid valves of a water pump cooperation, the water pump goes out the water direction and need not change, through the reversal of solenoid valve control rivers direction, whole device is simple as a result, convenient operation is reliable.
And a regulating valve is arranged between the outlet of the water pump and the fourth electromagnetic valve. The water yield and the backwashing water quantity can be controlled, and the backwashing effect is ensured.
The first electromagnetic valve and the fourth electromagnetic valve are normally open electromagnetic valves, and the second electromagnetic valve and the third electromagnetic valve are normally closed electromagnetic valves. The normally open and the normally closed can be respectively controlled by switching on and off the power supply, so that the control means is simplified, and the use convenience is improved.
The utility model has the advantages that: the membrane water outlet and the back flushing can be realized by using one single pump, the operation steps are optimized, the occupied area is reduced, and the investment cost of equipment is reduced.

Detailed Description
Example (b):
referring to fig. 1-2, a single-pump linkage MBR membrane water outlet and backflushing device comprises an MBR membrane 1, a water pump 2 and a water tank 3, wherein a first electromagnetic valve 5 and a second electromagnetic valve 6 are arranged at the inlet of the water pump 2 in parallel, a third electromagnetic valve 7 and a fourth electromagnetic valve 8 are arranged at the outlet of the water pump 2 in parallel, the first electromagnetic valve 5 and the third electromagnetic valve 7 are respectively connected with the outlet of the MBR membrane 1 in parallel, and the second electromagnetic valve 6 and the fourth electromagnetic valve 8 are respectively connected with the water tank 3 in parallel. And a regulating valve 4 is arranged between the outlet of the water pump 2 and the fourth electromagnetic valve 8.
Parallelly connected first solenoid valve 5 and second solenoid valve 6 at 2 entrances of water pump, parallelly connected third solenoid valve 7 and fourth solenoid valve 8 at the export, when the MBR membrane 1 goes out water, first solenoid valve 5 and fourth solenoid valve 8 keep opening, second solenoid valve 6 and third solenoid valve 7 keep closing, it can pass through first solenoid valve 5 to go out water, 2 entrances of water pump, 2 exports of water pump, the water tank 3 is sent into to the fourth solenoid valve 8, when needs recoil, first solenoid valve 5 and fourth solenoid valve 8 keep closing, second solenoid valve 6 and third solenoid valve 7 keep opening, the backwash water in the water tank 3 passes through 2 entrances of water pump, 2 exports of water pump in order and gets into and recoil in the MBR membrane 1. Just so realize that the single pump linkage goes out water and recoil operation to the MBR membrane through four solenoid valves of a water pump cooperation, the water pump goes out the water direction and need not change, through the reversal of solenoid valve control rivers direction, whole device is simple as a result, convenient operation is reliable.
The first solenoid valve 5 and the fourth solenoid valve 8 are normally open solenoid valves, and the second solenoid valve 6 and the third solenoid valve 7 are normally closed solenoid valves. For convenient control, a time relay 9 can be arranged to control the four electromagnetic valves to be switched on and off. The four electromagnetic valves are respectively electrified and powered off by setting time at the time relay 9, so that the normally open electromagnetic valve and the normally closed electromagnetic valve are respectively kept in different valve opening and closing states when the four electromagnetic valves are electrified and powered off, and the automatic control of water outlet and backwashing is realized. A timer may also be used to control the four solenoid valves.
The above detailed description is specific to one possible embodiment of the present invention, and the embodiment is not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the scope of the present invention should be included within the scope of the present invention.
