Description

A kind of pause control device pulling open filter plate device

Technical field

The utility model belongs to filter plant field, more particularly to a kind of pause control device pulling open filter plate device.

Background technology

Filter plant refers to the mechanical equipment or device for being filtered, and is that general filter common in industrial production is set Standby to be totally divided into two classes of vacuum and pressurization, there are commonly rotating cylinder, disk, horizontal belts etc. for vacuum types, and there are commonly pressures for pressurization class Filter, squeezing, dynamic filtration and rotary-type etc., chamber-type press filter are the one kind of class filter plant of pressurizeing, and the filter chamber of plate and frame has one Block tablet filter plate and one piece of hollow filter frame composition, filter cloth are fixed on sheet frame, and operation principle, which is the surface of filter plate, fiber crops Point and boss have through-hole to supporting filter cloth on the center and corner of filter plate, complete channel is constituted after assembling, can be passed through outstanding Supernatant liquid, washings and extraction filtrate；Filter plate both sides respectively have handle rest on crossbeam, and filter plate is compressed by pressing device, filter plate it Between filter cloth seal；Under the pressure effect of dehvery pump, it would be desirable to which the feed liquid of filtering is sent into each filter chamber, passes through Filter medium namely selects suitable filter cloth according to different industries, and solid and liquid are detached, form filter residue on filter cloth, directly Filter cake is formed to full of filter chamber, filtrate passes through filter cloth and flow to lower section fluid hole channel along filter plate groove, concentrates discharge；It has filtered Finish, cleaning can be passed through and wash water washing filter residue；After washing, it is also passed through compressed air sometimes, removes remaining cleaning solution.Filtering terminates Filter press removal filter cake is opened afterwards, and filter cake storage is between two neighboring filter plate, cleans filter cloth, and pressure plate filter again starts next Working cycles；It when cleaning filter plate, needs filter plate pulling open a determining deviation, to clean, existing drawing device mostly uses greatly Machine automatization pulls open, and during pulling open, the problems such as bonding due to filter plate, often will appear and pulls open by force, to cause filter plate On filter cloth damage.

Invention content

The phenomenon that filter cloth is easily damaged when pulling open filter plate for existing filter press, the utility model proposes one kind to pull open The pause control device of filter plate device, it is characterised in that：Including sensor, fixed plate, torsional spring, swing arm, limiting plate, fixed spiral shell Nail；The sensor is mounted on the body of filter press；The fixed plate be mounted on filter press body on it is described Sensor closes on；The torsional spring is mounted between fixed plate and swing arm；The swing arm is mounted on fixed plate by arm shaft On, it can be swung around arm shaft；The limiting plate is mounted in fixed plate, installation site corresponding with the other end of swing arm It should be guaranteed that swing arm should cover sensor when swing arm is contacted with limiting plate；The fixing screws are mounted in fixed plate and pressure Filter body connects.

Advantageous effect

The beneficial effects of the utility model are that it is possible to realize that filter press suspends during pulling open filter plate and pulls open action, It reduces filter press and damages filter cloth when pulling open filter plate.

1. sensor, 2. fixed plates, 3. torsional springs, 4. swing arms, 5. limiting plates, 6. fixing screws.

Fig. 2 is the right side structural representation of the utility model Fig. 1

1. sensor, 2. fixed plates, 3. torsional springs, 4. swing arms, 5. limiting plates, 6. fixing screws.

Specific implementation mode

In order to further illustrate the technical solution of the utility model, in conjunction with the specific embodiment party of the description of the drawings present invention Formula is selected commercially available close switch to be used as sensor 1, is installed on filter press body as shown in Figure 1, Figure 2, in this example, and with Pull open the power control system connection of filter plate mechanism；Fixed plate 2 is installed near the sensor 1 on filter press body；It will pendulum The arm shaft of arm 4 is mounted in fixed plate 2, and torsional spring 3 is mounted on arm shaft, two feet of torsional spring 3 respectively with fixed plate 2 It is connected with swing arm 4, installation site ensures that swing arm 4 can cover sensor 1 when being swung around arm shaft；Limiting plate 5 is consolidated Dingan County ensures that swing arm 4 when swinging to limiting plate 5 and being contacted with limiting plate 5, can cover sensor 1 in fixed plate 2, Fixed plate 2 is mounted on body using fixing screws 6, just completes the implementation of the utility model；In application, in torsional spring 3 Under effect, one end of swing arm 4 is contacted with limiting plate 5, and swing arm 4 covers sensor 1, at this point, filter plate mechanism normal work is pulled open, when When the problems such as encountering adhesion, artificial lift swing arm 4 so that swing arm 4 is swung, and is detached from covering sensor 1, and sensor 1 sends out signal To the control system for pulling open filter plate mechanism, make to pull open filter plate mechanism and be stopped, the problems such as artificial treatment adhesion, works as issue handling After complete, unclamp swing arm 4, under the action of torsional spring 3 swing arm 4 come back to limiting plate 5 contact position, it is normal to pull open filter plate mechanism Work.
