Abstract
The utility model discloses a kind of feeding device, including head tank, head tank one end is connect with feed pipe, and the other end is connect with feeder sleeve, is connected by control valve between head tank and the air accumulator of an air compressor.The invention also discloses a kind of filter press with the feeding device, including at least two filter plate, the head tank is connected by the appearance material cavity of feed pipe and filter plate.The utility model is compared to the prior art advantageously：Feed fast and stable.
Description
Technical field
The utility model is related to a kind of feeding device, it can be widely applied to chemical industry, food, Treatment of Sludge industry are set
It is standby to wait fields.
Background technology
The relevant industries such as traditional papermaking, brewing, Treatment of Sludge, the side that the higher material of water content is separated by solid-liquid separation
Method mainly uses the filter plants such as centrifugal dehydrator, belt filter press, plate and frame filter press, vacuum press filter to utilize filter medium
Apply certain pressure to material, filter out solid from liquid, to achieve the purpose that separation of solid and liquid.
Existing filter press generally uses the piston rod of master cylinder to be connect with pressure plate, is pushed away by the piston rod stretching of master cylinder
Dynamic pressure plate makes to be arranged several filter plates between pressure plate and thrust plate and closes up, and then carries out press filtration, main after the completion of press filtration
Large number of bulky filter plate is pulled open using electric tool, filter cake is allowed to fall by the piston rod backhaul of oil cylinder successively；Then again
Filter plate is closed up.Existing filter press conveys sludge during press filtration, by the appearance material cavity of feed pump toward each filter plate,
Charging rate is slow, is reaching setting feed pressure, the driving variable-frequency motor of screw pump accurately can not slow down or stop, and wink occur
Between feed pressure fluctuation, thus it is unstable, filter plate is impacted big, is easy the filter plate distending for making to close up, sludge is caused to reveal, shadow
Ring press filtration effect.
It is therefore desirable to be improved.
Utility model content
In view of the deficienciess of the prior art, one of the purpose of this utility model is to provide a kind of charging fast and stable
Feeding device, the two of the purpose of this utility model is to provide a kind of filter press being made of the feeding device.
To achieve the goals above, following technical solution is provided：
A kind of feeding device, it is characterised in that：Including head tank, head tank one end is connect with feed pipe, the other end and confession
Expects pipe connects, and is connected by control valve between head tank and the air accumulator of an air compressor.
Preferably, it is provided with check valve on the pipeline of the feed pipe.
Preferably, the head tank is equipped with upper limit position switch and lower position switch.
Preferably, the upper limit position switch and lower position switch are floating-ball level switch.
Preferably, the gravitation tank is equipped with pneumatic ball valve.
Preferably, the feeder sleeve is equipped with check valve.
Preferably, the check valve is prefill valve.
The filter press constituted using above-mentioned feeding device, it is characterised in that：The filter press includes at least two filter plate,
The head tank is connected by the appearance material cavity of feed pipe and filter plate.
With the above structure, the utility model is compared to the prior art advantageously：The utility model structure
Simply, fast and stable is fed.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model feeding device and filter press.
Specific implementation mode
The embodiment of the utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one, referring to Fig.1, filter press provided by the utility model include pairs of mating pressure plate 1 and thrust plate
3, it is provided with 2~120 filter plates 2 between pressure plate 1 and thrust plate 3, is additionally provided with for the appearance material cavity feed to filter plate 2
Feeding device.The feeding device includes head tank 5, and 5 one end of head tank is connect with feed pipe 6, and the other end passes through feeder sleeve 7
It connect with the appearance material cavity of filter plate 2, is connected by control valve 8 between the air accumulator 4 of head tank 5 and an air compressor.Air
Compressor is widely used at present, and structure and principle are same as the prior art, and which is not described herein again.
Feed pump 61 and check valve 62 are disposed on the pipeline of the feed pipe 6.Check valve 62 can prevent sludge from returning
Stream.
The head tank 5 is equipped with upper limit position switch 01 and lower position switch 02.When upper limit position switch 01 detects sludge
When liquid level signal, the sludge in head tank has reached predetermined volumes, and feed pump 61 stops charging；When lower position switch 02 detects
When sludge liquid level signal, closing control valve 8 stops being sent into compressed air into head tank 5, and feeder sleeve also stops the appearance to filter plate
Expect that cavity conveys sludge.
The upper limit position switch 01 and lower position switch 02 can be displacement sensor, laser transmitter or liquid-level switch
Deng.The upper limit position switch 01 and lower position switch 02 that the present embodiment uses are floating-ball level switch.
The utility model has the beneficial effects that：
1) (this capacity is more than needed for filter press single press filtration suction certain capacity head tank from feed pipe in advance
Amount) sludge, this process can filter press carry out press filtration work while carry out, when completing in a upper press filtration period, into
Batch can, which has been laid in, enough waits for press filtration sludge.
2) when being fed, it is sent into compressed air from the air accumulator of air compressor to head tank, sludge is forced to flow to filter plate
Hold material cavity, fill process fast and stable impacts filter plate small.
3) by the way that upper limit position switch and lower position switch is arranged, the capacity in head tank reaches the position of upper limit position switch
When, control feed pump stops charging；When the capacity in head tank is reduced to the position of lower position switch, stop into head tank
It is sent into compressed air, and then stops feed.
Pneumatic ball valve 9 is additionally provided on the head tank 5, when the liquid level in gravitation tank reaches the position of lower position switch 02,
Air compressor stops being sent into compressed air into gravitation tank 5, and control valve 8 is closed, and still there are compressed airs in tank.Work as feed
When tank restarts charging, opens pneumatic ball valve 9 and bleed off the compressed air in tank.
The pipeline of the feeder sleeve 7 is equipped with check valve 71.Prefill valve check valve 71 can prevent sludge reflux.The present embodiment
The middle check valve used is prefill valve.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
