Embodiment
Referring to figs. 1 through Fig. 7, the Anti-blocked bottom valve embodiment that the utility model is used for treatment tank is described further.
For an Anti-blocked bottom valve for treatment tank, comprise upper valve body 5 and lower valve body 1, be provided with the one-way valve for preventing waste liquid from flowing backwards in upper valve body 5, when centrifugal pump quits work, one-way valve can be closed in time.Upper valve body 5 top is provided with water output connector, and water output connector is connected with the suction piping of centrifugal pump, and the waste liquid sucking centrifugal pump first enters centrifugal pump again after the filtration of bottom valve.In lower valve body 1, split is provided with filtering screen 3, and filtering screen 3 is the drum-shaped of hollow, and guard upper end is provided with opening, and guard lower end is provided with dome, the dome of filtering screen 3 sidewall and lower end is equipped with filter opening 33.Filter opening 33 is uniformly distributed along the circumference on filtering screen 3.Filtering screen 3 inside is fixed with the impeller 4 for driving filtering screen 3 to rotate, impeller 4 and filtering screen 3 axes normal, when the centrifugal pump is operated, waste liquid outside filtering screen 3 enters filtering screen 3 from the filter opening 33 filtering screen 3, and upwards flow into upper valve body 5, impact force can be produced to the impeller 4 be fixed on filtering screen 3 when waste liquid upwards flows, make impeller 4 drive filtering screen 3 to rotate together in lower valve body 1.Lower valve body 1 lower end is provided with the scraper plate 2 for striking off filtering screen 3 outer wall undissolved substance, when the centrifugal pump is operated, filtering screen 3 rotates, and produces relative movement with the scraper plate 2 be arranged on lower valve body 1, scraper plate 2 can strike off the undissolved substance accumulated in outside filter opening 33, prevents filter opening 33 from blocking.Due to centrifugal pump work time, filtering screen 3 is rotating always, and scraper plate 2 can strike off the undissolved substance outside filter opening 33 in time timely, even if the less filter opening 33 that also can effectively prevent of filter opening 33 blocks.
Upper valve body 5 and lower valve body 1 are all formed by plastics integrated injection molding, plastics manufacture is adopted to be because plastic corrosion-resisting is strong, the waste water that pharmaceutical industry produces has corrosivity mostly, use plastics manufacture can extend the working life of bottom valve, integrated injection molding forms and can greatly cut down finished cost, and has higher precision.Lower valve body 1 is fixed on upper valve body 5 lower end outer wall by screw thread, and installing/dismounting is easy, fast.
Filtering screen 3 top is provided with flange 32, and flange 32 upper-end surface and upper valve body 5 lower surface are conflicted.The liquid produced when the centrifugal pump is operated fails to be convened for lack of a quorum and produces an impact force upwards to filtering screen 3, flange 32 and upper valve body 5 lower surface are conflicted and can be limited the position of filtering screen 3, guarantee that filtering screen 3 outer wall contacts with scraper plate 2, the undissolved substance being attached to filtering screen 3 outer wall is struck off by scraper plate 2.
Filtering screen 3 inner bottom surface is integrally formed with fixed base, fixed base center is provided with tapped hole, impeller 4 water entering surface is integrally formed with the stud 41 coordinated with tapped hole, impeller 4 and stud 41 are all made of plastics, low price, easy to process, injection machine integrated injection molding can be had, bolt is set directly on impeller 4, decreases the quantity of accessory.Sense of rotation when impeller 4 works with fitting seat 31 tightening direction and impeller 4 is identical, can play the effect of a self-tightening when impeller 4 rotates, and prevents from causing impeller 4 to come off between impeller 4 and fitting seat 31 due to thread looseness, easy to maintenance.
Impeller 4 water entering surface is provided with chamfering 42, can reduce the resistance of current, waste liquid be flowed more smooth and easy, can not cause energy loss unnecessary too much on impeller 4 water entering surface, increase flow resistance when waste liquid enters bottom valve and upwards flows.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
