Description
Technical field
The present invention relates to a kind of reducing mechanism of scraper centrifugal machine remnants filter cakes.
Background technology
Filter residue on bowl wall because centrifugal action usually forms abundant bulk, and scraper edge and filter bag it
Between need to retain certain interval to prevent scratching filter bag, the use of scraper is difficult merely and the efficiency of scraper removing by its scraped clean
Also it is not high.The more existing doctor blade device that broken filter cake is rolled with roller, although certain fragmentation can be played to filter cake,
It is that the filter residue for taking turns bottom point can be more pressed on filter bag securely to form some circle slag marks when roller is blocked up, when roller is excessively thin
Bad filter bag is easily cut, using effect is bad.
The content of the invention
The technical problems to be solved by the invention are：There is provided one kind can make filter cake understand that clean thoroughly scraper centrifugal machine is residual
The reducing mechanism of remaining filter cake.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of scraper centrifugal machine remnants filter cakes
Reducing mechanism, including the cylinder body being arranged on scraper support, cylinder body is interior to be provided with piston, and piston is provided with push rod, and push rod one end is worn
Go out cylinder body, and its end is substantially flush with scraper edge position during push rod ejection, on push rod between inboard wall of cylinder block and piston
Part on be arranged with spring, one end away from spring is provided with medium channel on cylinder body, and medium channel is connected with delivery hose,
Delivery hose is provided with the reversal valve of control delivery hose interval break-make.
As a kind of preferable scheme, the import of the medium channel is located at the position of face scraper support, the scraper
Support is provided with the sprocket hole connected with medium channel, and the delivery hose is connected at sprocket hole.
As a kind of preferable scheme, the piston side is provided with locating slot, and the spring one end is located in locating slot.
As a kind of preferable scheme, the side surface of piston face medium channel one is provided with locating ring.
As a kind of preferable scheme, the end that the push rod stretches out cylinder body is tapered.
The beneficial effects of the invention are as follows：The reducing mechanism of this scraper centrifugal machine remnants filter cakes is simple in construction, easy to use, adopts
Intermittently filter cake is crushed with compressed gas or liquid driven piston driving push rod, filter cake is swelled in block, Bu Huizao
Into adhesion of the filter residue on filter bag, it is easy to scraper filter cake to remove clean thorough.
The import of the medium channel is located at the position of face scraper support, and the scraper support is provided with and medium channel
The sprocket hole of connection, the delivery hose are connected at sprocket hole, and delivery hose is connected on the inside of scraper support, at work not
It is easily impaired.
Because piston side is provided with locating slot, the spring one end is located in locating slot, avoids spring and drives push rod to exist
Double swerve during motion so that the sealing between push rod and cylinder body is hardly damaged, the service life of extension fixture.
Because the side surface of piston face medium channel one is provided with locating ring, piston be fully retracted after again air inlet when, gas
Body active area is increased to locating ring inner circle area by gas channel cross-sectional area, can relatively easily promote piston movement.
Because the end of push rod stretching cylinder body is tapered, filter cake of being more convenient for crushes.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
As shown in figure 1, a kind of reducing mechanism of scraper centrifugal machine remnants filter cakes, including the cylinder being arranged on scraper support 1
Body 2, cylinder body 2 is interior to be provided with piston 3, and piston 3 is provided with push rod 4, and the one end of push rod 4 passes cylinder body 2, and its end during the ejection of push rod 4
It is substantially flush with scraper edge position, the end of push rod 4 is tapered.Part on push rod 4 between the inwall of cylinder body 2 and piston 3
On be arranged with spring 5, the side of piston 3 is provided with locating slot, and described one end of spring 5 is located in locating slot.
One end away from spring 5 is provided with medium channel 21 on cylinder body 2, and medium channel 21 is connected with delivery hose 6, conveying
Flexible pipe 6 is provided with the reversal valve 7 of the control interval break-make of delivery hose 6.The side surface of 3 face medium channel of piston 21 1 is provided with fixed
Position ring.The import of medium channel 21 is located at the position of face scraper support 1, and the scraper support 1 is provided with and medium channel 21
The sprocket hole 11 of connection, the delivery hose 6 are connected at sprocket hole 11.
So that medium is gases at high pressure as an example, the operation principle of the present apparatus is：After scraper tentatively strikes off the filter cake on filter bag,
Gases at high pressure in delivery hose 6 are by the sprocket hole 11 on scraper support 1, into cylinder body 2, promote entering for piston 3 and push rod 4
To motion, while delivery hose 6 controls via reversal valve 7 and interval in cylinder body 2 is supplied gas, and when stopping supplying, piston 3 is due to bullet
The effect of the elastic force of spring 5 drives push rod 4 to bounce back, and is acted on so as to realize that push rod 4 moves back and forth on remaining filter cake so that remaining filter cake
Loosely, and under the follow-up cutting of scraper so that remaining filter cake falls into hopper.
The principle and its effect of the above embodiments only illustrative the invention, and the implementation that part uses
Example, not for the limitation present invention；It should be pointed out that for the person of ordinary skill of the art, wound of the present invention is not being departed from
On the premise of making design, various modifications and improvements can be made, these belong to protection scope of the present invention.
