Abstract
The invention discloses an apparatus for continuously crushing dried starch in a starch production line. The apparatus comprises a feeding airlock and a discharging airlock, a starch crusher and a solid-gas separation bucket are arranged between the feeding airlock and the discharging airlock, a starch conveying pipeline between the starch crusher and the feeing airlock is provided with an air supplying device, a gas outlet of the solid-gas separation bucket is connected with a deduster through an exhaust pipeline, a tail gas outlet of the deduster is connected with a draft fan through a draft pipeline, a solid outlet of the deduster is connected with a dedusting airlock, a discharging port of the dedusting airlock is connected with a starch recovery port of the solid-gas separation bucket through a starch recovery pipeline, and an explosion venting device is arranged on the deduster. The apparatus can crush airflow-dried starch, allows finally obtained starch to have a required fineness without sieving, and has a large processing capability and a high safety performance.
Description
Technical field
The present invention relates to starch-making equipment technical field, in the continuous production line of especially a kind of large flow starch, for dry starch, carry out the device of pulverizing continuously.
Background technology
Cornstarch is important industry, food and medicine raw material, different purposes have different requirements to the fineness of starch, the percent of pass of the cornstarch 100 mesh sieve faces that conventional corn starch flow waterline is produced is 98 ~ 99%, but when starch user has higher requirement to starch fineness, while being not less than 99.5% as the percent of pass of 100 mesh sieve faces, need to carry out screen to the starch after pneumatic conveying drying, screen process adopts vibratory sieve to process conventionally, but because reciprocating sieve disposal ability is lower, be generally 8-10 ton/hour, for output, reach the large-scale Starch Production streamline of 60 tons/hour, need a lot of vibratory sieves, not only take up an area space large, and because compass screen surface is often blocked, steady and continuous operation is also difficult to guarantee, environment dust is very large simultaneously, can bring very large potential safety hazard to workshop.
Summary of the invention
The technical problem that invention will solve is: provide in a kind of Starch Production line dry starch is carried out to the device of pulverizing continuously, this device can be pulverized the starch after pneumatic conveying drying, make finished product starch just can reach desired fineness without screen, this device disposal ability is large, and security performance is high.
The technical scheme that technical solution problem is taked: in a kind of Starch Production line, dry starch is carried out to the device of pulverizing continuously, comprise feeding airlock and discharge airlock, between feeding airlock and discharge airlock, be provided with starch pulverizer and solid and gas separating bucket, starch feeding hole of pulverizer is connected with feeding airlock discharging opening by starch transfer pipeline, starch pulverizer discharging opening is connected with the charging aperture of solid and gas separating bucket by starch transfer pipeline, the solid and gas separating bucket discharge gate material airlock that runs in, on the starch transfer pipeline between starch pulverizer and feeding airlock, be provided with air-compensator, the gas discharge outlet of solid and gas separating bucket connects deduster by gas exhaust piping, the exhaust port of deduster connects air-introduced machine by induced pipe, the solid discharge mouth of deduster connects dedusting airlock, the discharge gate of dedusting airlock connects the recovery of starch mouth of solid and gas separating bucket by recovery of starch pipeline, on deduster, be provided with explosion venting device.
Described starch pulverizer is starch impact grinding.
Described deduster is sack cleaner.
Described explosion venting device is explosion relief door or venting of dust explosion film.
Beneficial effect: in Starch Production line of the present invention, dry starch is carried out to the device of pulverizing continuously, owing to having collected seed, comprise feeding airlock and discharge airlock, between feeding airlock and discharge airlock, be provided with starch pulverizer and solid and gas separating bucket, starch feeding hole of pulverizer is connected with feeding airlock discharging opening by starch transfer pipeline, starch pulverizer discharging opening is connected with the charging aperture of solid and gas separating bucket by starch transfer pipeline, the solid and gas separating bucket discharge gate material airlock that runs in, on the starch transfer pipeline between starch pulverizer and feeding airlock, be provided with air-compensator, the gas discharge outlet of solid and gas separating bucket connects deduster by gas exhaust piping, the exhaust port of deduster connects air-introduced machine by induced pipe, the solid discharge mouth of deduster connects dedusting airlock, the discharge gate of dedusting airlock connects the recovery of starch mouth of solid and gas separating bucket by recovery of starch pipeline, on deduster, be provided with the technical scheme of explosion venting device, by the starch after pneumatic conveying drying is pulverized with pulverizer again, make finished product starch without sieving, can reach the requirement of client to fineness, 100 mesh sieve face percent of pass are stable to be reached more than 99.5%, and unit interval treating capacity is large, owing to pulverizer being arranged between feeding airlock and discharge airlock, the wind producing when starch pulverizer is rotated by servicing unit is drained, prevent that starch from meeting naked light and blasting in crushing process, and on deduster, be provided with explosion venting device, even if starch is blasted in crushing process, under feeding airlock and the blocking-up of discharge airlock and the protection of explosion venting device, can not damage the starch packing department in the starch drying section of upstream and downstream, security performance is high, owing to having adopted described deduster, be the technical characterictic of sack cleaner, improved the capture effect of starch, both reduced the powder loss in shallow lake, prevented that again starch suspension from bringing hidden danger to safety in production in air, owing to having adopted described explosion venting device, be the technical characterictic of explosion relief door or venting of dust explosion film, venting of dust explosion better effects if, safe coefficient is higher.
