Description
Technical field:
This utility model relates to the extraction defecator of a kind of biological pesticide, is specifically related to a kind of avilamycin and extracted
On-line filtration device in journey.
Background technology:
Avilamycin is a kind of low toxicity, and efficiently, high selection, green, environment-friendly type, biogenic insecticide, it is fully solved
Traditional pesticide exists environment is produced the problem polluted, and is the emphasis of China " the Seventh Five-Year Plan " " eight or five " " 95 " and Eleventh Five-Year Plan is attacked
Pass project, along with the universal of avilamycin in recent years and downstream product with promote, has not only driven China's agricultural, animal husbandry big
Power develops, and promotes agriculture-stock production and move towards green, and innoxious direction changes.As the most maximally efficient killing at present
The avilamycin of one of worm agent, domestic usage amount is about about 2500 tons, becomes the main product in agricultural chemical insecticide.
In current avermectin extracting technique, extraction post is as the equipment used in avermectin extracting technique, because of it
Use airtight filter operation system and dynamic elution processes, with short production cycle, low cost and by increasing A Wei
Rhzomorph manufacturer substitutes, with it, the equipment that sheet frame extracts as avilamycin mycelia；But the leaching that present each producer is used generally
Carry post all to there is problems in that and a set of (general simple can use filter cloth pressurization by long-term reusable defecator owing to not having
Bar, as clarification filtration device, uses filter ruffle to add the pipe bucket device as dust catching of boring), each batch materials completes one
After individual leaching process, being required for operator and enter tank and go to change filter material, this not only extends the production cycle, increases the work of employee
Intensity, and restricted clearance operation to the safety of employee bring very big hidden danger (employee enters tank operation and easily causes and stir wound, suffocates,
The harm such as poisoning).
Summary of the invention:
For the deficiencies in the prior art, this utility model provides on-line filtration device during a kind of avilamycin extraction,
This defecator, without entering tank operation, can be reused for a long time, and equipment availability safety is low, greatly reduces the production cycle.
The technical solution of the utility model is as follows:

This utility model is preferred, and the filtering accuracy of double-layer stainless steel mesh grid is 300～400 mesh.
The filtering accuracy of double-layer stainless steel mesh grid of the present utility model draws through long-term experiment, filtering accuracy mistake
The big rate of filtration that not only can affect dynamic desorption liquid, it is even more important that mycelia easily remains in mesh grid, affects mesh grid
Life-span；Precision is too small, then leakiness mycelia during filtration, affects filter quality.
Clarification filtration device of the present utility model, when dynamic desorption, is used for separating solid dreg and filtrate, double-deck stainless
Steel mesh grid use stainless steel, and on have thicker punching web plate as protection, so this device extraction equipment " steam
Wine " straight-through high-temperature steam time, filter material will not deform and wrinkle or carbonization；Further, since double braid net is relative to filter cloth, burn
Knotting, the permeability of the filter material such as core is preferable, extract post when carrying out dynamic desorption and filtering in mesh grid residual thin
Dreg can blow out when solvent is reclaimed in steam blowback, it is ensured that the life-time service of drainage screen, it is not necessary to change.
This utility model is preferred, described rustless steel punching net, the shape of double-layer stainless steel mesh grid, size and sieve plate
Unanimously.
This utility model is preferred, and described rustless steel punching net is the circle being spliced into by multiple bar shaped rustless steel punching nets
Shape punching net, each bar shaped rustless steel punching net and double-layer stainless steel mesh grid by press strip, be bolted on sieve plate.
It is further preferred that described rustless steel punching net is to be spliced by 5 bar shaped rustless steel punching nets.
This utility model is preferred, and the filtering accuracy of double braid net filter cylinder is 300～400 mesh.
This utility model is preferred, and alcohol spray equipment includes drip washing house steward, the end of drip washing house steward is provided with drip washing and props up
Pipe, central supported skeleton is fixed on drip washing house steward and goes up and be positioned at drip washing arm periphery, and double braid net filter cylinder is sleeved on center and props up
Fix outside support bone frame and by clip.
This utility model is preferred, a length of the 800～1000mm of double braid net filter cylinder.
This utility model is preferred, and the end of double braid net filter cylinder is blocked by double braid net, the mistake of double braid net
