Abstract
The utility model discloses a grinding system with a pneumatic butterfly valve, and provides a grinding production system with a pneumatic flange type butterfly valve. According to the technical scheme, the grinding system with the pneumatic butterfly valve comprises a feeding machine, a grinding machine, a grading machine, a powder collector, a matched pulse ash removing device, the pneumatic flange type butterfly valve, an air valve and a fan, and is characterized in that the pneumatic flange type butterfly valve is arranged in front of an inlet of the air valve and is interlocked with the grading machine. By the grinding system, the production rate of waste and degraded products is reduced to zero, and the production efficiency is improved; and the grinding system is suitable for grinding production of powder processing enterprises.
Description
Technical field
The utility model relates to a kind of scratch system with Pneumatic butterfly valve, especially a kind of abrasive dust production system with pneumatic flange form butterfly valve.
Background technology
Existing abrasive dust production system generally comprises batcher, main frame (being abrasive dust equipment), grader, conveyance conduit, powder collector, blower fan, product packing machine; There is air inlet the lower part of main frame; From the main frame to the blower fan, be the system of sealing, pneumatic flange form butterfly valve is not installed.
At present abrasive dust production system conveyance conduit generally has only a manual air-valve to regulate ventilation at the fans entrance place, perhaps carries out speed governing and regulates ventilation through install frequency converter additional at blower motor.Because the rotating speed of blower fan is higher than grader usually, and the weight of draught fan impeller is also much bigger than the grading wheel weight of grader, so the motional inertia of blower fan is more much bigger than grader.Have a power failure or when causing tripping operation because of the equipment reason, even if blower fan and grader cut off the power supply simultaneously, grader and blower fan still will rotate a period of time owing to motional inertia when running into.Because the motional inertia of grader is much littler than blower fan; So when grader shuts down; Blower fan is still owing to action of inertia is being rotated; So still there is certain negative pressure in system, this negative pressure is enough to particle diameter in the powder is extracted in the powder collector through the grader that has stopped operating at the particle more than 75 microns, and diameter is called as coarse granule at the particle more than 75 microns in the powder industry.Coarse granule is fatal defective to powder product; It will produce very big loss to the application industry of powder; So will but also will shut down coarse granule residual in the system be cleared up there being coarse grained product to scrap processing, scrap otherwise will have influence on more powder product.When the cleaning coarse granule; Often since some corners can't clear up thoroughly, so also must be with the time of at least 16 hours even several days, adopt the normal boot-strap production powder that gives up could the coarse granule of corner be brought out; Thereby cause very big loss, production cost is improved greatly.
Pneumatic butterfly valve is made up of pneumatic actuator and butterfly valve.Pneumatic butterfly valve is to use the circular butterfly plate that rotates with the valve mandarin orange to do keying property, mainly does the block valve use to realize the operated pneumatic valve of launching action, also can be designed with the function that adjusting or section valve are held concurrently and regulated.Butterfly valve commonly used has two kinds of wafer type butterfly valve and flange form butterfly valves.The wafer type butterfly valve is with stud valve to be connected between two pipe flanges, and the flange form butterfly valve is to have flange on the valve, with bolt two end flanges on the valve is connected on the pipe flange.
In recent years relate in the patent documentation in the product of various abrasive dust production systems, also do not use pneumatic flange form butterfly valve.The patent No. of announcing like Chinese patent information centre is 200720014394 utility model---a kind of carbonaceous material pulverizing system, this patent is not used pneumatic flange form butterfly valve.
The utility model content
The purpose of the utility model is that a kind of abrasive dust production system with pneumatic flange form butterfly valve will be provided, and runs into faults such as tripping operation, power failure and is easy to generate coarse grained problem to solve existing flour mill production line.
Its technical scheme is: a kind of scratch system with Pneumatic butterfly valve; Comprise batcher, flour mill, grader, powder collector, supporting pulse ash remover, pneumatic flange form butterfly valve, air-valve, blower fan; It is characterized in that: pneumatic flange form butterfly valve is installed in air-valve inlet front, and interlocks with grader.
When grader ran well, this Pneumatic butterfly valve was often opened; When grader caused that because of power failure, equipment reason tripping operation causes the tripping of grader switch, this Pneumatic butterfly valve was promptly closed rapidly, even if at this moment grader stops, blower fan because Pneumatic butterfly valve is closed, just can not produce coarse granule still in running.
Do not have the abrasive dust production system of pneumatic flange form butterfly valve relatively, the beneficial effect of the utility model is in the past:
1, avoids producing coarse granule, reduced the products material loss, reduced production cost.
2, the waster generation rate is reduced to zero, has improved production efficiency.
Description of drawings
Fig. 1 is the abrasive dust production system structural representation of the utility model band Pneumatic butterfly valve;
Fig. 2 is pneumatic flange form butterfly valve and grader interlocking sketch map;
Among Fig. 1--1. flour mill, 2. batcher, 3. grader, 4. powder collector, 5. supporting pulse ash remover, 6. pneumatic flange form butterfly valve, 7. air-valve, 8. blower fan;
Among Fig. 2--the 1st, the fan operation contactor is often driven auxiliary contact, the 2nd, and auxiliary contact, the 3rd often left by the grader contactor, the electromagnetic valve coil of Pneumatic butterfly valve.
The specific embodiment
Embodiment in the face of the utility model combines accompanying drawing to describe in detail down.
As shown in Figure 1; A kind of abrasive dust production system with Pneumatic butterfly valve is made up of following equipment: comprise flour mill 1, batcher 2, grader 3, powder collector 4, supporting pulse ash remover 5, pneumatic flange form butterfly valve 6, air-valve 7, blower fan 8; It is characterized in that: pneumatic flange form butterfly valve 6 is installed in air-valve 7 inlet fronts, and interlocks with grader 3.
The method of pneumatic flange form butterfly valve and grader interlocking: when grader runs well; Fan operation A.C. contactor 7KM2 adhesive, the normally opened contact 1--7KM2 of Fig. 2 is closed, grader A.C. contactor 6KM adhesive; The normally opened contact 2--6KM of Fig. 2 is closed; The Pneumatic butterfly valve electromagnetic valve coil 3 of Fig. 2 gets electric, and Pneumatic butterfly valve is opened, and does not influence the ordinary production of abrasive dust production system; And when grader tripped because of unexpected power failure, equipment reason cause, 1 among Fig. 2,2 contacts were broken off, electromagnetic valve coil 3 outages; Pneumatic butterfly valve is closed immediately, even if at this moment grader stop and blower fan still in running, because Pneumatic butterfly valve closes; System's negative pressure disappears, and just can not produce coarse granule.
