Abstract

The invention discloses an automatic flushing method and device for a fiber washing sieve. Cases of the washing sieve are connected in series with each other through bushings at middle parts; shaft sleeves are arranged in the bushings, plain shaft are arranged in the shaft sleeves, and chains are fixed on the plain shafts; chains and chain wheels on main shafts of motors form kinematic pairs; the motors drive the chain wheels to lead the chains to do axial reciprocating linear movement; each case of the washing sieve is also internally provided with a cambered spray pipe; the cambered spray pipes are located at the rear parts of washing sieve pieces and fixed on the plain shafts through fixing bolts; high pressure hoses are connected with the cambered spray pipes; a plurality of solid cone spray nozzles are uniformly mounted on the cambered spray pipes to form spray mechanisms; the spray mechanisms which are capable of axially moving are mounted at the rear part of the washing sieve; and high-pressure water columns sprayed by the nozzles flush materials in the seams of the fiber washing sieve out. The device provided by the invention is mounted in post-sieving washing sieve cases, repair operations, such as sieve piece replacement, are not influenced, flushing is carried out on the device after sieving, flushing effect is good, operation is simple, closed flushing ensures clean field environment, non-stop flushing is realized, and running hours of the washing sieve are increased.

Description

A kind of fiber wash sieve auto-flushing method and device

Technical field

The present invention has supplied a kind of fiber wash sieve auto-flushing method and device, is to the improvement of the feed liquid separation equipment in the industry production such as starch, papermaking, food, chemical industry, belongs to the food processing machinery technical field.

Background technology

In the food processing machinery technical field, used fiber wash sieve in use for some time sieve seam will be affected separating effect by feed blocking, needs often flushing.Conventional method is regularly to shut down in the front to open the door with the giant flushing, and this method need be by the platform cleaning, and inefficiency, cleaning performance is poor, labour intensity is high, and materials from spattering affects environmental sanitation during flushing.

Summary of the invention

The present invention discloses a kind of fiber wash sieve auto-flushing method and device, has solved the blockage problem of fiber wash sieve in the production process.

Fiber wash sieve auto-flushing method provided by the invention and device, its technical solution is as follows:

Sleeve pipe by the middle part between the washing screen box body is connected in series, be axle sleeve in the sleeve pipe, optical axis is sleeved in the axle sleeve, is fixed with chain on the optical axis, sprocket wheel on chain and the electric machine main shaft consists of kinematic pair, drives chain by the motor-driven sprocket wheel and does the axial reciprocating rectilinear motion; Also be provided with the arc jet pipe in each washing screen box body, the rear portion that the arc jet pipe is positioned at the washing sieve is fixed on the optical axis by set bolt, and high-pressure hose links to each other with the arc jet pipe, several solid-cone (type) nozzles evenly is installed on the arc jet pipe is consisted of spraying mechanism.

Good effect of the present invention is:Washing sieve rear portion be provided with can be axial mobile spraying mechanism, the water jets under high pressure of nozzle ejection is rinsed the material in the fiber wash sieve seam well; The present invention washs in the screen box body after being installed in sieve, does not affect maintenance activities such as changing sieve, can realize multiple linkage according to field layout.Apparatus of the present invention are good, simple to operate in sieve afterflush, developing result, and airtight flushing has guaranteed the site environment cleaning, and has realized not shutting down flushing, Effective Raise the operation man-hour of washing sieve.

The specific embodiment

According to shown in Figure 1, (the present embodiment is 3) is connected in series by the sleeve pipe 1 of middle part between the washing screen box body 9 of apparatus of the present invention, be axle sleeve 2 in the sleeve pipe 1, optical axis 4 is sleeved in the axle sleeve 2, chain 3 is fixed on the optical axis 4 and consists of kinematic pairs (with reference to Fig. 3) with sprocket wheel 10 on motor 11 main shafts, drives chains 3 by motor 11 drive sprockets 10 and does the axial reciprocating rectilinear motion; Such as Fig. 2, Fig. 3, shown in Figure 4, the rear that also is provided with arc jet pipe 6 and is positioned at washing sieve 12 in each washing screen box body 9, arc jet pipe 6 is fixed on the optical axis 4 by set bolt 8, high-pressure hose 7 links to each other with arc jet pipe 6, several solid-cone (type) nozzles 5 evenly are installed corresponding to the surface of washing sieve 12 on the arc jet pipe 6, can be carried out spary to washing sieve 12.Motor 11 drives through sprocket wheel 10 that chains 3 and jet pipe 6 are parallel does linear reciprocating motion with washing sieve 12, and the water jets under high pressure by nozzle 5 ejections in motion process will clean up the compass screen surface of washing sieve 12.

Claims

1. a fiber wash is sieved automatic flushing device, it is characterized in that: the sleeve pipe by the middle part between the adjacent two washing screen box bodies is connected in series, be axle sleeve in the sleeve pipe, optical axis is sleeved in the axle sleeve, be fixed with chain on the optical axis, sprocket wheel on chain and the electric machine main shaft consists of kinematic pair, drives chain by the motor-driven sprocket wheel and does the axial reciprocating rectilinear motion; Also be provided with the arc jet pipe in each washing screen box body, the rear portion that the arc jet pipe is positioned at the washing sieve is fixed on the optical axis by set bolt, and high-pressure hose links to each other with the arc jet pipe, several solid-cone (type) nozzles evenly is installed on the arc jet pipe is consisted of spraying mechanism.
