Description

Abrasive material sundry removing structure of Raymond mill
Technical Field
The utility model relates to a raymond machine inner structure specifically is a abrasive material debris structure is got rid of to raymond machine.
Background
The Raymond mill comprises a milling main machine, an analyzer, a blower, a finished product cyclone separator, a pipeline device, a motor and the like, wherein the milling main machine comprises a rack, an air inlet volute, a scraper knife, a grinding roller, a grinding ring, a housing and a motor.
The working principle of the Raymond mill is as follows: the material is crushed to the required granularity and then is conveyed to a storage hopper by a lifter, the material is uniformly and continuously conveyed into a grinding chamber of a grinding main machine by a vibrating feeder, a grinding roller swings outwards and is tightly pressed on a grinding ring under the action of centrifugal force during rotation, a scraper knife shovels the material and conveys the material to a grinding area formed between the grinding roller and the grinding ring, the purpose of crushing the material is achieved by rolling the grinding roller on the grinding ring, fine powder after the material is ground is brought into an analyzer along with circulating air of an air blower for separation, the material with the fineness being too coarse falls back to the bottom of a base cavity for regrinding, and qualified fine powder enters a finished product cyclone powder collector along with air flow and is discharged through a powder outlet pipe to obtain a finished product.
The more the sundries which are difficult to grind in the materials are gathered at the bottom of the seat cavity of the base, and the sundries are mixed in the materials and are repeatedly sent to the grinding area for grinding, which is an important reason causing the grinding efficiency of the main grinding machine to be low; sundries sent to the grinding area along with the materials can also partially enter the air return box to influence the air inlet effect; sundries are accumulated too much and need to be stopped for cleaning, and the working efficiency of the main grinding machine is also influenced.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a ray machine of in time cleaing away debris in the abrasive material gets rid of abrasive material debris structure to the not enough of prior art.
The Raymond mill that can solve above-mentioned technical problem gets rid of abrasive material debris structure, its technical scheme includes the base of crocus host computer, the lateral part circumference equipartition of base has seted up the seat chamber of air intake and base and has communicated with each other, is equipped with the spiller mechanism with host computer main shaft synchronous revolution in the seat chamber of base, is equipped with the return air case wherein with the air intake cladding on the base, the difference is the bin outlet has still been seted up on the lateral part of base and has communicated with each other with seat chamber lower part, offers out to dodge the mouth corresponding to the bin outlet on the box of return air case, and the feeding section of a conveyer gets into the return air case and is connected with the bin outlet from dodging the mouth, is equipped with in the seat chamber of base corresponding to the bin outlet and scrapes the material mechanism with spiller mechanism or host computer main shaft synchronous pivoted.
The utility model has the advantages that:
1. the utility model discloses the abrasive material debris structure is got rid of to the raymond machine adopts the conveyer in time to discharge the sedimentary abrasive material debris of base seat chamber bottom outside the mill room of crocus host computer, has avoided the repetition to mill to abrasive material debris, has effectively improved crocus host computer efficiency of milling, has reduced the noise, has prolonged the working life of crocus host computer.
2. The utility model discloses because of in time having clear away abrasive material debris, avoided abrasive material debris to get into the return-air tank, improved the air inlet effect.
3. The utility model discloses effectively reduced and shut down the maintenance number of times to the raymond mill, improved work efficiency.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
And (3) identifying the figure number: 1. a base; 1-1, an air inlet; 2. an air return box; 3. a blade mechanism; 4. a main machine main shaft; 5. a conveyor; 6. grinding a ring; 7. and (4) grinding the roller.
Detailed Description
The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.
The utility model discloses abrasive material debris structure is got rid of to raymond mill, base 1, return-air case 2 and conveyer 5 including the crocus host computer.
The grinding ring 6 is coaxially installed at the upper part of the seat cavity of the base 1, air inlets 1-1 are uniformly distributed on the circumference of the side part of the base 1 below the grinding ring 6, each air inlet 1-1 is communicated with the seat cavity of the base 1, and a discharge port is formed between every two adjacent air inlets 1-1; a relief knife mechanism 3 which rotates synchronously with a main machine main shaft 4 is arranged in a seat cavity of the base 1, a grinding roller mechanism is arranged on the main machine main shaft 4 through a fixed roller frame, and grinding rollers 7 which are aligned with a grinding ring 6 to form a grinding area are uniformly distributed on the circumference of the grinding roller mechanism, as shown in figure 1.
The air return box 2 is arranged at the top of the base 1, each air inlet 1-1 and the discharge port on the side part of the base 1 are coated by the box body of the air return box 2, an avoiding port with the same height as the discharge port is formed in the box body of the air return box 2 corresponding to the discharge port, and the horizontal feeding section of the conveyor 5 extends into the box body of the air return box 2 from the avoiding port and is connected with the discharge port; a scraping mechanism is arranged in a seat cavity of the base 1 corresponding to the discharge port, and the scraping mechanism and the main machine spindle 4 rotate synchronously, or the scraping mechanism and the scraper knife mechanism 3 rotate synchronously, as shown in fig. 1.
