Abstract

The utility model relates to a dry-typed dust-removing grinder composed of a grinding wheel, a grinding wheel dust sucking protective hood, an electric motor, a draught fan and a dust collector. The utility model is characterized in that a two-grade dust-removing mechanism of inertia dust collection and cloth bag dust filtration is used; the grinding wheel dust sucking protective hood is provided with an inertia inlet used for dust fall by the inertia and a plurality of dust sucking openings of low-pressure areas; the dust collector is provided with an inertia chamber and a dust remover chamber in which the method of a plurality of cloth bag dust filtration is used and the gravitation of the draught fan is used for the purified air discharge into space. Compared with the existing grinder, the utility model has the advantages of good dust sucking effect, high dust removing effect, convenient operation and maintenance for cleaning dust, reliable operation, etc.

Description

Dry-type two-grade dust-removing grinder

The utility model relates to a kind of cleaning type abrasive machine, is specially adapted to the cleaning of reconditioning cutter, workpiece in the industrial and mining enterprises and deburring etc.

In technique known, what the dust shield of abrasive machine adopted is the mono-hull cover, the cloth bag of a Chalk-dust filtering is housed in the disposal box, when grinding, because the thickness grit that dust shield produces in the time of can't be with grinding separately, red-hot oarse-grained grit directly falls on the cloth bag, easily causes cloth bag by the situation of scaling loss.The tiny micronic dust of other flies upward the space with the rotation wind of emery wheel by the case cover outlet, and human body and environment are all worked the mischief.China's patent 86204786 discloses a kind of desk-top cleaning type abrasive machine, this machine adopts inertia control of dust and negative pressure wet dust removal mechanism, the exit of dust shield and emery wheel increases to be had the air channel and plate washer is housed, liquid is adopted in the filtration of dust, tiny micronic dust can be caught the purpose that dirt reaches purified treatment by air channel and liquid, improved dust removing effects greatly, but this machine exists after emery wheel is worn, the gap of emery wheel and plate washer increases, and makes to take out the decline of dirt effect, and the liquid that contains dust simultaneously is difficult for discharging, cleaning is got up, very trouble causes labour intensity big, defectives such as maintaining inconvenience.

At the problem that above-mentioned prior art exists, the purpose of this utility model provides a kind of good dedusting effect, and the cleaning dust is convenient, and the dedusting air quantity is little, and noise is little, the dry type two-stage grinder with dust collector of convenient operating maintenance.

Realize that the scheme that the utility model is taked is: in the disposal box of abrasive machine, be provided with the inertia chamber, dust catcher chamber, separate by dividing plate between two Room, not connected, the middle part is provided with a plurality of low-pressure area suction ports two suction ports preferably is set in the rear wall of emery wheel dust shield, the coarse granule that produces during sharpening can directly enter the inertia chamber by the inertia inlet, attracted the micronic dust that by emery wheel, when running to the negative pressuren zone suction port with emery wheel, under the graviational interaction of air-introduced machine, enter dust catcher chamber, a plurality of cloth bags are housed in the dust catcher chamber, be used for Chalk-dust filtering, purify air, and be discharged into the space through the outlet of air-introduced machine.In order to prevent that the cloth bag surface from being blocked by dust stratification, the vibration cleaning device also is housed in disposal box, the pedal in the dust remover that tramps with one's feet when needing just can make the dust stratification on cloth bag surface fall to, and the dust stratification in the disposal box can be regularly with manually draining.

Utilize accompanying drawing to further specify embodiment of the present utility model below.

Fig. 1 is the front appearance figure of abrasive machine;

Fig. 2 is the cut-away view of abrasive machine;

Fig. 3 is the cutaway view of I-I among Fig. 1.

Referring to Fig. 1, label 1 is an emery wheel, is installed in the emery wheel dust suction protective cover 4, is located on the disposal box 2 with driving emery wheel motor rotating 3, and label 8 is dust catcher chamber's shelves lids, label the 9, the 10th, inertia chamber deashing shelves lid.

Referring to Fig. 2, Fig. 3 is provided with inertia chamber A and the B of dust catcher chamber in the disposal box 2 of abrasive machine, and separate with dividing plate A1.A2.12, not connected between each chamber, enter the porch of dust suction protective cover 4 by the emery wheel direction of rotation when dust, by inertia inlet E, directly fall into the inertia chamber.Middle part in the rear wall of emery wheel dust suction protective cover 4 is equipped with plate washer 13,14 and is formed two low-pressure area suction port C, D, suction port C, D and the B of dust catcher chamber and directly be used to lead to, and the gravitation by air-introduced machine 6 can pump the dusts in the dust suction protective cover 4.All the time be in low-pressure state in the dust suction protective cover in order to make, in the exit of emery wheel 1 with dust suction protective cover 4, be equipped with one and regulate plate washer 11, which is provided with elongated slot, after emery wheel is worn, can regulate the gap of plate washer 11 and emery wheel 1 by the slip of adjustment screw in elongated slot, thereby obtain better pick-up performance.In the B of dust catcher chamber, a plurality of filtration cloth bags 15 are housed, more than at least two, and upward install on the ventilating duct 16 that is sealed in the B of dust catcher chamber by ring flange, the inlet of the outlet of ventilating duct 16 and air-introduced machine 6 is directly connected.In order to remove the dust stratification on cloth bag surface, in case cloth bag blocks, avoid flowing resistance to increase, also be provided with a vibration cleaning device 7 in the bottom of disposal box 2, dust remover by turning cylinder, pedal, beat grey handle, spring is formed, one end of rotating shaft is equipped with a pedal, and the other end is being fixed one and beaten grey handle, beats on the grey handle spring is housed, when foot pedal, spring is elongated, and when pin unclamps, beats grey handle under the pulling force effect of spring, return suddenly, strike falls the ash of cloth bag on cloth bag, prevents that dust from stopping up the effect that the cloth bag influence purifies air.

In sum, grinder with dust collector of the present utility model is compared with present existing cleaning type abrasive machine, and it is good to have pick-up performance, the efficiency of dust collection height, and the characteristics such as cleaning dust and convenient operating maintenance, after measured, the absolute value of breathing zone dust concentration is not more than 1.5mg/m³, noise is not more than 75 decibels.
