Abstract
The utility model relates to waste water lifting equipment which comprises a water diversion tank. One end of the water diversion tank is connected with a water inlet pipe, and the other end of the water diversion tank is connected with a water outlet pipe. The water inlet pipe is connected with a waste water pool. The waste water lifting equipment is characterized in that the top of the water diversion tank is connected with an exhaust pipe connected with an electromagnetic valve, the electromagnetic valve is connected with a contactor connected with a self-sucking pump, and the self-sucking pump is arranged on the water outlet pipe. When the waste water lifting equipment is used, pump idle is not caused, automatic control degree is good, and service life is long.
Description
Technical field
The utility model relates to a kind of waste water lifting system.
Background technology
Common waste water lifting system all is to adopt centrifugal pump, self-priming water pump or submersible pump at present.General wastewater equalization pond is all underground, and the pond is darker, and centrifugal pump commonly used is difficult to waste water is aspirated up.Use stainless submersible pump, because submersible pump is expensive, and in wastewater disposal basin, waste water has corrosion and toxicity, is difficult for the maintenance of pump, generally can use self priming pump to cooperate water diversion tank to use together.But common water diversion tank is because easy entrained air causes pump idle running, when pump dallies not in time discovery, will cause the damage of machine envelope or the motor of pump to burn out.In order to address the above problem, need to send the special messenger to check, in time find pump idle running, also need close down equipment, add the tank diversion, just waste water is raised up again, make troubles to production.
The utility model content
When providing a kind of use, the technical problems to be solved in the utility model can not cause pump idle running, the waste water lifting system of automatically controlling degree better and growing application life.
For solving this technical problem, the technical solution of the utility model is as follows:
A kind of waste water lifting system, comprise water diversion tank, one end of water diversion tank connects water inlet pipe, the other end connects outlet pipe, and water inlet pipe is connected in the wastewater disposal basin, it is characterized in that: the top at water diversion tank is connected to stack, be connected to electromagnetic valve on the stack, electromagnetic valve is connected with contactor, and contactor connects self priming pump again, and self priming pump is installed on the outlet pipe.
Adopt the waste water lifting system of technique scheme, open self priming pump, shut electromagnetic valve, the water in the wastewater disposal basin enters water diversion tank by water inlet pipe, enters next process by outlet pipe again.When self priming pump is closed down, electromagnetic valve is opened, gas in the water diversion tank is by outside the stack drain tank, the return of waste water of high-order inlet channel is in water diversion tank, so that self priming pump is when closing down at every turn, it is abundant that the water yield in the water diversion tank keeps, when avoiding next self priming pump to restart, because the water yield is inadequate, air amount causes self priming pump idle running.
Description of drawings
Fig. 1 is the structural representation of the utility model waste water lifting system.
The specific embodiment
As shown in Figure 1, a kind of waste water lifting system comprises water diversion tank 4, and an end of water diversion tank 4 connects water inlet pipe 5, and the other end connects outlet pipe 6.Be connected to stack 3 at the top of water diversion tank 4, be connected to electromagnetic valve 7 on the stack 3, electromagnetic valve 7 is connected by electric wire 8 with contactor 2, and has received on the self priming pump 1 by electric wire 8 another contact of contactor 2, self priming pump 1 is installed on the outlet pipe 6, and water inlet pipe 5 is connected in the wastewater disposal basin 9.
This waste water lifting system is opened self priming pump 1, shut electromagnetic valve 7, and the water in the wastewater disposal basin 9 enters in the water diversion tank 4 by water inlet pipe 5, enters the next process water inlet by outlet pipe 6 again and processes.When equipment is out of service, close self priming pump 1, open electromagnetic valve 7, return of waste water is to water diversion tank 4 in the outlet pipe 6, in order to prevent water diversion tank 4 Air resistances, air in the water diversion tank 4 is discharged by stack 3, and after water diversion tank 4 was filled water, unnecessary waste water was back in the wastewater disposal basin 9 by water inlet pipe 5.When self priming pump 1 restarted, electromagnetic valve 7 cut out, and waste water is thus lifted to high-order reaction tank gradually.
Claims (1)
1. waste water lifting system, comprise water diversion tank, one end of water diversion tank connects water inlet pipe, the other end connects outlet pipe, and water inlet pipe is connected in the wastewater disposal basin, it is characterized in that: the top at water diversion tank is connected to stack, be connected to electromagnetic valve on the stack, electromagnetic valve is connected with contactor, and contactor connects self priming pump again, and self priming pump is installed on the outlet pipe.
