The mud cake feeder that is used for centrifugal dehydrator
Technical field
The present invention relates to yi, gif kind feeder relates in particular to yi, and the gif kind is used for the mud cake feeder of centrifugal dehydrator.
Background technology
At present, in the desulfurization wastewater treatment technology, often to use the horizontal spiral centrifugal dehydrator.In the process of cleaning centrifugal dehydrator, the rinse water that flows down from centrifugal dehydrator enters bucket or conveying worm from the mud cake outlet easily, and moisture content of the cake raises, solid content reduces thereby cause, and influences mud cake quality.
Simultaneously, bucket is when fortune mud truck unloads mud cake, and the mud cake higher with moisture content that mix owing to rinse water can cause mud to splash, and influences environment.
Therefore, be necessary to propose yi in fact, the mud cake feeder that is used for centrifugal dehydrator that the gif kind is novel is to overcome above-mentioned defective.
Summary of the invention
The object of the present invention is to provide yi, the gif kind is used for the mud cake feeder of centrifugal dehydrator, can avoid that rinse water enters bucket when centrifugal dehydrator cleans.
The mud cake feeder that is used for centrifugal dehydrator of the present invention is design like this:
Yi, the gif kind is used for the mud cake feeder of centrifugal dehydrator, comprise: with centrifugal dehydrator flange connecting, mud cake feeder body, be positioned at the mud cake outlet of mud cake feeder body below, also comprise: push-pull valve and drainage arrangement, described push-pull valve is located between mud cake feeder body and the mud cake outlet, and described drainage arrangement is connected to the sidewall of described mud cake feeder body.
Preferably, described drainage arrangement comprises: the sidewall that rinse water delivery pipe, described rinse water delivery pipe pass mud cake feeder body is communicated with described mud cake feeder body.And more preferably, described rinse water delivery pipe is provided with manual ball valve.
Preferably, described push-pull valve is the electrodynamic type push-pull valve.
Preferably, described push-pull valve is the pneumatic type push-pull valve.
Preferably, described push-pull valve is butterfly valve or disconnecting link valve.
With respect to prior art, mud cake feeder provided by the invention has guaranteed the quality that mud cake is produced, and can realize having protected environment to cleaning the collection of waste water.
Description of drawings
Fig. 1 is a feeder structural representation of the present invention;
Fig. 2 is the vertical view of feeder shown in Figure 1;
Fig. 3 is the side view of feeder shown in Figure 1.
The specific embodiment
Fig. 1 is a feeder structural representation of the present invention, and Fig. 2 is the vertical view of feeder shown in Figure 1, and Fig. 3 is the side view of feeder shown in Figure 1.Mud cake feeder 1 comprises flange 10, mud cake feeder body 12, is positioned at mud cake outlet 14, push-pull valve 16 and the drainage arrangement 18 of mud cake feeder body 12 belows.
As shown in the figure, the edge of described flange 10 has a plurality of screws.By described screw, flange 10 is connected with the centrifugal dehydrator (not shown), flange 10 can with mud cake feeder body 12yi, the gif body forms (for example by casting), or is connected yi by modes such as welding, bolt connections, gif rises.
The inwall of mud cake feeder body 12 is the slope shape of predetermined angular, so that mud cake landing successfully, and skids off from mud cake outlet 14.Mud cake outlet 14 can with external component, for example conveying worm connects by bolt.
Push-pull valve 16 is located between mud cake feeder body 12 and the mud cake outlet 14, by the bolt hole at two ends, exports 14 bolts with mud cake feeder body 12 and mud cake respectively and is connected.Wherein, described push-pull valve 16 can be electrodynamic type push-pull valve or pneumatic type push-pull valve.
Described drainage arrangement 18 is connected the below yi of described mud cake feeder body 12, gif side.Preferably, drainage arrangement 18 comprises rinse water delivery pipe 180 and manual ball valve 182.Described rinse water delivery pipe 180 is connected the below yi of described mud cake feeder body 12, gif side.And, on rinse water delivery pipe 180, can be provided with manual ball valve 182, by opening manual ball valve 182, rinse water can be discharged from rinse water delivery pipe 180.
When centrifugal dehydrator is normally carrying out sludge dewatering when operation, push-pull valve 16 is opened, mud cake after the centrifugal dehydration enters mud cake feeder 1 from centrifugal dehydrator, skids off from mud cake outlet 14 by mud cake feeder body 12, stores the back and outwards carries by conveying worm.
When centrifugal dehydrator stops sludge dewatering and enters cleaning process, push-pull valve 16 cuts out, and the rinse water that centrifugal dehydrator flows down is dammed by push-pull valve 16, open manual ball valve 182 after, rinse water enters sewage collection system from rinse water delivery pipe 180, has avoided the pollution to environment.
Push-pull valve 16 among the present invention can be butterfly valve or disconnecting link valve.
By adopting centrifugal dehydrator mud cake feeder of the present invention, can avoid rinse water to enter bucket, influence mud cake quality, and can realize preventing the pollution of the environment cleaning the collection of waste water.
It will be understood by those skilled in the art that the present invention is not limited to the description of present embodiment, any in the claim scope of being added change or revise all in the scope of protection of present invention.
