Sewage collecting treating apparatus
Technical field
The utility model relates to a kind of sewage collecting treating apparatus.
Background technology
Sewage collecting treating apparatus is the visual plant of chemical plant in order to collection and treatment sewage, and current used sewage collecting treating apparatus mainly comprises sewage collecting pool, fluid pump and Sewage Disposal. The course of work of above-mentioned sewage collecting treating apparatus is: the sewage that chemical plant produces while carrying out workshop cleaning or workshop appliance cleaning, can enter sewage collecting pool through the open drain in workshop, chemical plant, then the sewage in manual observation sewage collecting pool holds to certain liquid level, restart fluid pump, now fluid pump is pumped to Sewage Disposal by the sewage in sewage collecting pool and carries out sewage disposal. The shortcoming of above-mentioned sewage collecting treating apparatus is: (1) is because sewage collecting pool is generally built in outside workshop, chemical plant, and the upper transverse plane of sewage collecting pool is lower than workshop terrace, in the time that workman does not have to observe the liquid level of sewage collecting pool in time because of work mistake, very easily there is sewage collecting pool liquid spill-over phenomenon, thereby make sewage flow to plant area ground or other region outward, plant environment is caused to secondary pollution; (2) after fluid pump is by the sewage suction in sewage collecting pool, workman Yi Yin work is neglected and is forgotten and close fluid pump, thereby causes fluid pump to be damaged in idling conditions.
Utility model content
The purpose of this utility model is to provide a kind of sewage collecting treating apparatus that can effectively prevent sewage collecting pool spill-over and submerged pump idle running.
For achieving the above object, the utility model has adopted following technical scheme: described sewage collecting treating apparatus, it is characterized in that: comprise sewage collecting pool, submerged pump, in order to control the control system of submerged pump start and stop, and Sewage Disposal, the inlet of described submerged pump is immersed in the liquid of sewage collecting pool, the liquid outlet of submerged pump is connected with Sewage Disposal by outlet pipeline, in sewage collecting pool, be provided with vertical rod, magnetic switch and magnetic switch on being from up to down arranged at intervals with successively in vertical rod, the height of upper magnetic switch is lower than the upper surface of sewage collecting pool, the height of magnetic switch is higher than the inlet of submerged pump, upper magnetic switch is electrically connected with control system with magnetic switch simultaneously, in vertical rod, going back movable sleeve is provided with and can moves up and down and respond to mutually with magnetic switch the magnetic ball float coordinating along vertical rod, when under the buoyancy of magnetic ball float liquid in sewage collecting pool when moving to magnetic switch position in vertical rod, upper magnetic switch can send the signal that starts submerged pump to control system, control system receive magnetic switch send enabling signal after can start submerged pump, in the time being displaced downwardly to magnetic switch position along vertical rod under the buoyancy of magnetic ball float liquid in sewage collecting pool, magnetic switch can send and stop the signal of submerged pump to control system, and control system can stop submerged pump after receiving the stop signal that magnetic switch sends.
By the enforcement of technique scheme, the beneficial effects of the utility model are: can be by the liquid automatic control in sewage collecting pool between the inlet height of the upper surface of sewage collecting pool height and submerged pump by cooperatively interacting of magnetic switch, magnetic ball float, control system and submerged pump, not only effectively prevent sewage collecting pool generation spill-over, make the liquid in sewage collecting pool can not cause secondary pollution to plant area, and effectively avoid submerged pump because idle running damages the generation of phenomenon, greatly extend the service life of equipment.
Brief description of the drawings
Fig. 1 is the structural representation of sewage collecting treating apparatus described in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, described sewage collecting treating apparatus, comprise sewage collecting pool 1, submerged pump 2, in order to control the control system 3 of submerged pump 2 start and stop, and Sewage Disposal 4, the inlet of described submerged pump 2 is immersed in the liquid of sewage collecting pool 1, the liquid outlet of submerged pump 2 is connected with Sewage Disposal 4 by outlet pipeline 5, in sewage collecting pool 1, be provided with vertical rod 6, magnetic switch 7 and magnetic switch 8 on being from up to down arranged at intervals with successively in vertical rod 6, the height of upper magnetic switch 7 is lower than the upper surface of sewage collecting pool 1, the height of magnetic switch 8 is higher than the inlet of submerged pump 2, upper magnetic switch 7 is electrically connected with control system 3 by the first connecting circuit 9, magnetic switch 8 is electrically connected with control system 3 by the second connecting circuit 10, in vertical rod 6, going back movable sleeve is provided with and can moves up and down and respond to mutually with magnetic switch the magnetic ball float 11 coordinating along vertical rod 6, when under the buoyancy of magnetic ball float 11 liquid in sewage collecting pool 1 when moving to magnetic switch 7 position in vertical rod 6, upper magnetic switch 7 can send the signal that starts submerged pump 2 to control system 3, control system 3 can start submerged pump 2 after receiving the enabling signal that magnetic switch 7 sends, in the time being displaced downwardly to magnetic switch 8 position along vertical rod 6 under the buoyancy of magnetic ball float 11 liquid in sewage collecting pool 1, magnetic switch 8 can send the signal that stops submerged pump 2 to control system 3, control system 3 can stop submerged pump 2 after receiving the stop signal that magnetic switch 8 sends, by upper magnetic switch 7, magnetic switch 8, magnetic ball float 11, cooperatively interacting of control system 3 and submerged pump 2 can be by the liquid automatic control in sewage collecting pool 1 between the height of sewage collecting pool 1 upper surface and the height of submerged pump 2 inlets, not only effectively prevent sewage collecting pool generation spill-over, make the liquid in sewage collecting pool can not cause secondary pollution to plant area, and effectively avoid submerged pump to damage the generation of phenomenon because of idle running, greatly extend the service life of equipment.
