The utility model content
For above-mentioned situation, the utility model provides a kind of crushing blower, and integrated blower fan and pulverizer function are simple in structure, easy for installation, and the former operation of must gradation carrying out can once be finished, and has significantly improved operating efficiency.
The basic structure of crushing blower of the present utility model, comprise with the gas-material inlet that is positioned at axial centre and the spiral case that is positioned at circumferential gas-material outlet, and arranging along the spiral case axial centre, and can be provided with by the main shaft of driving mechanism driven rotary the centrifugal air-supply structure of fan blade, between the radially far-end rotational trajectory and spiral case internal perisporium of fan blade, be provided with the comminuting space that volute space can be separated into centripetal part and the circle-shaped sieve that goes out material space of centrifugal part, also be provided with the pulverizing hammer leaf that in said comminuting space, rotates with main shaft through positioning connection structure on the main shaft.By in centrifugal air-supply structure, being provided with the sieve that the inside of centrifugal fan can be divided into material space and comminuting space, and the pulverizing hammer leaf that arranges in comminuting space with the main shaft rotation is used for beating pulverizing to what enter such as materials such as chaff shells, make material to be pulverized and gas be inhaled in the lump the interior comminuting space of spiral case, behind the pulverizing hammering crushing that is rotated with main shaft, reach and pulverize the sieve aperture that the fine crushing material that requires sees through sieve, through going out material space, blow out and collect by spiral case gas-material outlet with air-flow.
A kind of specific constructive form that can adopt, be to make the positioning connection structure of pulverizing hammer leaf of being located by connecting on the described main shaft for being fixed on hand hammer sheet folder and large hammer leaf folder on the main shaft through the spacer axially spaced-apart respectively, and fan blade is arranged along even circumferential and is fixedly connected on the large hammer leaf folder.In addition, also can be set directly on the main shaft independently respectively pulverizing hammer leaf and fan blade, can be all applicable with other structure that main shaft together rotates or can make fan blade and pulverize hammer leaf.
More direct convenience enter comminuting space after making material enter gas-material inlet, a kind of preferred mode is large hammer leaf sandwiched can be set to evenly to distribute in its outer peripheral edges to be provided with the disk-like structure of gas-material channel (such as the breach of appropriate format etc.).
On the basis of said structure, a kind of selectable mode is that described gas-material inlet is located on the cover of spiral case lateral wall.
For the ease of the fixing in spiral case of the sieve described in the said structure, the periphery of described sieve can be fixed in the draw-in groove of corresponding setting on the spiral case madial wall.
Except above-mentioned sieve fixed form, the mode that can also adopt, that lateral wall at spiral case is provided with cover, one side periphery of described sieve is fixed in the draw-in groove of corresponding setting on the spiral case madial wall, the opposite side periphery of sieve is the corresponding sieve collar location chucking that arranges on cover then, can more convenient installation or the operation of location chucking sieve during maintenance.
Crushing blower of the present utility model is integrated blower fan function and crushing function, install and use all very easily equipment, utilize the principle of centrifugal blower structure, will be by in comminuting matter and the gas in the lump inspiration spiral case, by the comminuting space that the spatial separation in the spiral case is become by sieve with go out material space, to blow out behind the crushing material that suck, saved the essential secondary operation operation of secondary legacy equipment, and the volume of this crushing blower is little, simple in structure, particularly with hulling machine, can increase work efficiency significantly when rice mill etc. are used, have very high market value and social benefit.
Below by the specific embodiment by the accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away from the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
Description of drawings
Fig. 1 is the side partial sectional view of the utility model crushing blower.
Fig. 2 is that the A of Fig. 1 is to partial sectional view.
The specific embodiment
The utility model crushing blower illustrated in figures 1 and 2, with the gas-material inlet 12 that is positioned at axial centre be positioned at the spiral case 1 of circumferential gas-material outlet 11, and along spiral case 1 axial centre setting, and can be provided with by the main shaft 8 of driving mechanism driven rotary the centrifugal air-supply structure of fan blade 2, lateral wall place at spiral case 1 is provided with cover 13, and described gas-material inlet 12 is located on the cover 13.Be connected with hand hammer sheet folder 6 and large hammer leaf folder 14 at main shaft 8.Large hammer leaf folder 14 is evenly distributed with the disk-like structure of the appropriate format gas-material channel such as breach for peripheral region outside.Fan blade 2 is arranged along even circumferential and is fixedly connected on and can presss from both sides on 14 with the large hammer leaf of main shaft 8 rotations, and each is pulverized hammer leaf 4 and also is fixedly connected on large hammer leaf folder 14 and the hand hammer sheet folder 6 through the spacer 5 on bearing pin 7 and the bearing pin respectively.Between the internal perisporium of the radially far-end rotational trajectory of fan blade 2 and spiral case 1, be provided with a circle-shaped sieve 3, go out material space 16 with what the interior spatial separation of spiral case became the comminuting space 15 of centripetal part and centrifugal part.One side periphery of this sieve 3 is fixed in the draw-in groove 19 of corresponding setting on spiral case 1 madial wall, and the opposite side periphery of sieve 3 is the corresponding sieve collar that arranges 17 location chuckings on cover 13.The large hammer leaf of disk-like structure presss from both sides the gas of 14 peripheral regions-material channel breach, can make and namely enter fast comminuting space after together being inhaled into by gas-material inlet 12 with air-flow by comminuting matter, after pulverizing hammer leaf 4 pulverizing with the main shaft rotation in this comminuting space, can can enter out material space 16 with air-flow by the fine powder of sieve 3, and after gas-material outlet 11 blows out, collect.Be provided with suitable installation screw 9 at spiral case 1.During use, with belt with transmission of power to primary shaft belt pulley 10, gas-material inlet 12 usefulness pipelines are connected on the corresponding discharging opening of required machinery (such as hulling machine, rice mill etc.); Material after gas-material outlet 11 connects cloth bag or other material-gathering device can collect pulverizing.
