Abstract

The invention discloses a crushing system, particularly a cyclic crushing system. The cyclic crushing system comprises an electric control cabinet, a raw material bin, a de-ironing separator, a vibrating feeder, a crushing machine, a collecting bin, a star-shaped discharging valve, an airflow sieve, a drought fan and a finished-product bin. Crushed materials are separated by using the airflow sieve, a qualified material is fed into the finished-product bin, and unqualified material is fed into a crushing chamber of the crushing machine and is crushed again until a finished product with a uniform particle size is obtained. A magnetic protection device preventing magnetic metal impurities from entering the crushing chamber is also arranged in the system, thus effectively removing fine metals may existing in the raw materials and ensuring quality of the finished product.

Description

A kind of circulation crushing system
Technical field
The present invention relates to a kind of crushing system, especially a kind of circulation crushing system.
Background technology
In the industries such as food, pharmacy, health products, chemical industry, agricultural chemicals, chitin, feed and powdery paints, often need the granularity large-sized solid material being ground into requirement, current crushing system is normally once pulverized raw material, raw material time of staying in pulverizing chamber is long, easily cause temperature too high, grinding particle size is uneven, wayward.Magnetic protection device is not set in system, affects finished product quality.
Summary of the invention
The object of the present invention is to provide a kind of circulation crushing system, airflow screen is utilized to be separated by the material after pulverizing, qualified material enters finished product bin, the pulverizing chamber that defective material returns pulverizer is pulverized again, repeat said process until raw material is all ground into qualified material, and obtain varigrained finished product by the screen cloth changing airflow screen.Set up magnetic protection device, can prevent magnetic metal foreign material from entering pulverizing chamber, the fine metal thing that effectively may contain in removing raw material, ensures finished product quality.
The technical solution adopted for the present invention to solve the technical problems is: the present invention includes electrical control cubicles, raw material cabin, tramp iron separator, oscillating feeder, pulverizer, collecting bin, star-shaped discharge valve, airflow screen, blower fan, finished product bin, airflow screen is connected with star-shaped discharge valve, finished product bin, pulverizer respectively, material after pulverizing enters airflow screen via star-shaped discharge valve and sieves, qualified material enters finished product bin, the pulverizing chamber that defective material enters pulverizer is pulverized again, ensure the finished product epigranular obtained, qualification rate is high.
Raw material cabin, tramp iron separator, oscillating feeder, pulverizer, collecting bin, blower fan are connected in turn; tramp iron separator adopts pipeline type permanent magnetism tramp iron separator as the magnetic protection device of crushing system; prevent magnetic metal foreign material from entering pulverizing chamber; when material passes through; effectively can remove the fine metal thing that may contain in raw material, ensure finished product quality.The negative-pressure air-flow that blower fan is formed in collecting bin collects the material after pulverizing, and collecting bin can carry out material collection, dedusting simultaneously, simplifies system composition, reduces floor space little, enhance productivity.
In order to make the temperature stabilization of pulverizing chamber, crushing system mounting temperature sensor, oscillating feeder can regulate rate of feeding automatically according to pulverizing chamber temperature and pulverizer electric current.Pulverizer band water-cooling apparatus, cooling water flows into the water jacket of pulverizing chamber through water inlet, is finally flowed out by delivery port, cools pulverizing chamber, and protection quality of material does not change, and increases the stability that pulverizer normally works, enhances productivity.
Star-shaped discharge valve, by variable-frequency motor regulating spool rotary speed, reaches the object of domination set feed bin discharge rate.
The invention has the beneficial effects as follows: compared with common large scale solid material crushing system, airflow screen is adopted to be separated by the material after pulverizing, qualified material enters finished product bin, and the pulverizing chamber that defective material returns pulverizer is pulverized again, finally can obtain even-grained finished product.Be provided with the magnetic protection device preventing magnetic metal foreign material from entering pulverizing chamber in system, the fine metal thing that effectively may contain in removing raw material, ensures finished product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1. electrical control cubicles, 2. raw material cabin, 3. tramp iron separator, 4. oscillating feeder, 5. pulverizer, 6. collecting bin, 7. star-shaped discharge valve, 8. airflow screen, 9. blower fan, 10. finished product bin in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Raw material cabin 2, tramp iron separator 3, oscillating feeder 4, pulverizer 5, collecting bin 6, blower fan 9 are connected in turn, form pulverizing and to gather materials system; Collecting bin 6, star-shaped discharge valve 7, airflow screen 8, pulverizer 5 connect successively, form comminuting matter screening system; Airflow screen 8, finished product bin 10 are connected, and form finished product gathering system.
Raw material in raw material cabin 2 flows through tramp iron separator 3, the fine metal thing that may contain in removing raw material, enter pulverizer 5 via oscillating feeder 4 to pulverize, blower fan 9 is bled in a large number, make to form negative-pressure air-flow in collecting bin 6, crushing rear material is sucked in collecting bin 6, material and air separate by the built-in cloth envelop collector of collecting bin 6, pure air after filtration is discharged in air by cloth envelop collector gas outlet, the plugging device of collecting bin 6 is by cloth envelop collector gas outlet seal, compressed air is blown into, cleaning and filtering from cloth envelop collector back blow port.
Star-shaped discharge valve 7 is connected with variable-frequency motor, by regulating spool rotary speed, regulates collecting bin 6 to the discharge rate of airflow screen 8.Material after pulverizing is separated by airflow screen 8, and qualified material enters finished product bin 10, and the pulverizing chamber that defective material returns pulverizer 5 is pulverized again.
Crushing system mounting temperature sensor, oscillating feeder 4 is connected with variable-frequency motor.The water jacket of pulverizing chamber is flow through in the chilled(cooling) water return (CWR) of pulverizer 5.
