Description

Oscillatory type coal dust cleaning sieve

Technical field

The utility model relates to sieve, is specially oscillatory type coal dust cleaning sieve.

Background technology

In the pulverized coal injection powder craft, can spray into blast furnace smoothly in order to guarantee coal dust, do not cause plugging to block up the rifle phenomenon, must adopt pulverized coal sieve that the foreign material in the coal dust are screened out.At present, the pulverized coal sieve of employing mainly contains rotary screen, vibratory sieve, reciprocating screen, gravity flow screen etc., and wherein general vibratory sieve moves back and forth and screening continuously by driving compass screen surface by vibrating motor, but or design for integral planar because of compass screen surface, cover surface is little, and screening effect is poor, changes the compass screen surface inconvenience; The compass screen surface edge does not have rib, foreign material are easily got rid of to the edge blocks compass screen surface, make it can't rotate even burn out motor, tiny foreign material fall down from the edge influences screening quality, and compass screen surface very easily stops up compass screen surface not from cleaning function, increase labor cleaning's number of times, influence ordinary production, must stir motor with hand during the labor cleaning, cleaning speed is slow, effort, dangerous.Or, make foreign material stop up sieve aperture because of Oscillation Amplitude can not be regulated, the sieve cover cleaning inconvenience, influence screening quality of pc.

The utility model content

The technical problem that the utility model solved is to provide oscillatory type coal dust cleaning sieve, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved realizes by the following technical solutions:

Oscillatory type coal dust cleaning sieve, comprise the coal dust hopper, screen cloth, the retaining ash wheel that removes slag, vibrating motor, slag-drip opening, screen box, frame, discharging opening, described coal dust hopper bottom is provided with screen cloth, described screen cloth right side is provided with the retaining ash wheel that removes slag, described vibrating motor top and screen cloth keep excellent contact, the right end of described screen cloth is provided with slag-drip opening, it under the described screen cloth screen box, the bottom of described screen box is communicated with discharging opening, described vibrating motor is fixed on the frame, described retaining ash removes slag to take turns and comprises wheel shaft, bearing block, fixing impeller, keep off grey scarfing cinder plate and regulate bracket, described bearing block is fixed on the wheel shaft, described fixedly impeller is fixed on the bearing block, the grey scarfing cinder plate of described retaining and regulate bracket and be fixed on successively fixedly on the impeller.

Beneficial effect

The utility model is because architecture advances, and under same appearance and size, its screening efficiency improves 2～4 times, and can prevent effectively that foreign material from being got rid of and block compass screen surface to the edge or fall down from the edge, and screening effect is good, quality is high; Labor cleaning's compass screen surface number of times can significantly reduce, and reduces fault rate and downtime, enhances productivity.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, Fig. 2, the front view of oscillatory type coal dust cleaning sieve, the left view of oscillatory type coal dust cleaning sieve, oscillatory type coal dust cleaning sieve, comprise coal dust hopper 1, screen cloth 2, the retaining ash removes slag and takes turns 3, vibrating motor 4, slag-drip opening 5, screen box 6, frame 7, discharging opening 8, described coal dust hopper 1 bottom is provided with screen cloth 2, described screen cloth 2 right sides be provided with the retaining ash remove slag the wheel 3, described vibrating motor 4 tops and screen cloth 2 keep excellent contact, the right end of described screen cloth 2 is provided with slag-drip opening 5, it under the described screen cloth 2 screen box 6, the bottom of described screen box 6 is communicated with discharging opening 8, and described vibrating motor 4 is fixed on the frame 7.

Referring to Fig. 3, Fig. 4, the left view of the grey wheel that removes slag of retaining in the front view of the grey wheel that removes slag of retaining, the oscillatory type coal dust cleaning sieve in the oscillatory type coal dust cleaning sieve, the described retaining ash wheel 3 that removes slag comprises wheel shaft 9, bearing block 10, fixedly impeller 11, the grey scarfing cinder plate 12 of retaining and adjusting bracket 13, described bearing block 10 is fixed on the wheel shaft 9, described fixedly impeller 11 is fixed on the bearing block 10, the grey scarfing cinder plate of described retaining 12 and regulate bracket 13 and be fixed on successively fixedly on the impeller 11.

During operation; open vibrating motor 4; vibrating motor 4 work drive screen cloth 2 and do the vibration that moves in circles, and add coal dust toward coal dust hopper 1; coal dust enters into screen cloth 2 by coal dust hopper 1; material on the sieve enters into retaining ash that screen cloth 2 right sides the are provided with wheel 3 that removes slag, and sieve material down enters into screen box 6, and discharge from discharging opening 8; the grey wheel 3 that removes slag of described retaining can block dust and the cinder that screen cloth 2 produces in screening process, play a protective role.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
