Abstract

A safe and dedusting grinder relates to a grinder of grinding process equipment, and comprises an engine base, a motor, a motor output shaft, an end cover, a bearing 5 and a bearing 5', wherein two ends of the output shaft are provided with a grinding wheel and a grinding wheel protective cover; the output shaft of the motor is prolonged to be 1100-1300 mm; a bearing 6 is added; a plurality of reverse inclined baffles are disposed in the grinding wheel protective cover; the lower part of the grinding wheel protective cover is provided with an opening; the opening is connected to an inlet of a dust receiving tube and an inlet of an air absorbing tube. The grinder uses three pairs of bearings to support the output shaft of the motor, so that the prolonged output shaft can run stably; the distance between the grinding wheels at two ends is increased, and the synchronous processing operations of two workers are convenient. The plurality of reverse baffles are disposed in the protective cover, so as to effectively prevent big particles and grinding wheel fragments from flying out. The front section of the dust receiving section is inclined along the tangent line direction; the big dust particles are collected into a dust receiving box by the movement inertia of particles. A dust collecting fan can collect tiny dusts, and purified air is discharged after a cloth bag is used for filtering the dusts. The measures realize dust collection and ensure the safe production.

Description

A kind of safety, grinder with dust collector

Technical field

The utility model relates to the abrasive machine of grinding equipment.

Background technology

The existing abrasive machine that is used to roughly grind has 3 weak points, and the one,, the motor output shaft that its two end is equipped with emery wheel is shorter, and the distance between two emery wheels is generally about 800mm, and during two people while process operation, it is bigger to interact.The 2nd,, existing abrasive machine uses dangerous, has emery wheel fragment, big sand dust grain to fly out from guard shield processing opening part and hurt sb.'s feelings often, and big injury accident takes place.The 3rd,, no matter the dust suppression of existing grinder with dust collector is wet method or dry method dust, all exists dust removing effects general, and does not together take into consideration with safety measure, has big potential safety hazard.

Summary of the invention

The goal of the invention of the utility model has two, first lengthening motor output shaft, make between two emery wheels between apart from strengthening, be beneficial to two people process operation simultaneously.It two is to adopt to simplify safety, dust suppression efficiently, makes it to realize in dedusting safety in production.

The foregoing invention purpose is so to realize, a kind of safety, grinder with dust collector, comprise support 1, motor 2, motor output shaft 3, electric motor end cap 4, bearing 5 and bearing 5 ', motor output shaft two ends install emery wheel 7 respectively, emery wheel is established guard shield 8, be characterised in that, motor output shaft 3 adds and grows to 1100-1300mm, sets up bearing 6 in motor end and end cap joint; The wheel-guard inwall is provided with the baffle plate 9 of the reverse inclination of polylith; Opening 19 is established in the wheel-guard bottom, it is connected mutually with dust fall tube inlet 10 and aspiration channel inlet 13 down, and the dust fall tube inlet connects dust fall case 12 through dust fall pipe 11, and the aspiration channel inlet connects induced-draught fan cabinet 15 through aspiration channel 14, the induced-draught fan cabinet has exhaust duct 18, and exhaust duct 18 connects the cloth bag dust filtration device.

This abrasive machine has increased bearing 6, adopts three pairs of bearings motor output shafts altogether, but makes the output shaft smooth operation of lengthening, has strengthened spacing between two emery wheels, for two people while process operation provides convenience.The guard shield inwall is provided with the baffle plate 9 of the reverse inclination of polylith, can stop flying out of big sand dust grain and emery wheel fragment, makes its deceleration and whereabouts, has realized safety in production.Dust fall pipe leading portion tilts along the guard shield tangential direction, utilizes the motional inertia of big sand dust grain to be collected into the dust fall case.Sweep-up pipe and dust absorption fan are set, utilize the negative pressure of aspiration channel porch to collect thin dirt, behind cloth bag filter dirt, discharge Purge gas again.Above-mentioned measure had not only realized dedusting but also had reached the purpose of safety in production.

The specific embodiment

1,2,3 given of the present utility model a kind of specific embodiment in conjunction with the accompanying drawings elaborate to the structure of the utility model.This safety, grinder with dust collector comprise support 1, motor 2, motor output shaft 3, end cap 4, bearing 5 and bearing 5 ', motor output shaft two ends install emery wheel 7 respectively, emery wheel has guard shield 8.Roughing sand expander motor output shaft is generally about 800mm, it is bigger to influence each other during two people while process operation, be unfavorable for work, the utility model adds motor output shaft and grows to 1100-1300mm, set up bearing 6 in motor two ends and end cap joint, make it common employing bearing 5, bearing 5 ' and 6 three pairs of bearings power transmission shafts of bearing, but make the output shaft even running of lengthening, output shaft can not deform when grinding big part, and armature can not swept thorax.

The baffle plate 9 of the reverse inclination of polylith is set along the wheel-guard inwall, so-called reverse inclination is meant and the emery wheel direction of rotation, so, and when emery wheel turns round, grit and broken grinding wheel will be subjected to stopping of reverse baffle plate and tackle, and significantly reduce the generation of the casualty accident that flies out.Opening 19 is established in the wheel-guard bottom, and it is connected mutually with dust fall tube inlet 10 and aspiration channel inlet 13.The dust fall tube inlet connects dust fall case 12 through dust fall pipe 11, and dust fall pipe 11 entrances tilt along the wheel-guard tangential direction, forms inertia district a, make with emery wheel together the grit of rotating operation will enter the dust fall pipe because of effect of inertia, fall into the dust fall case then.The aspiration channel inlet is because the draft of induced-draught fan, form negative pressuren zone b, make the thin dirt that can not enter dust fall pipe and dust fall case because of inertia, to be inhaled into aspiration channel 14, enter induced-draught fan cabinet 15 via aspiration channel 14, induced-draught fan comprises motor 17 and wind wheel blade 16, and the exhaust duct 18 through induced-draught fan cabinet top enters cloth bag dust filtration device (not shown) again, the Purge gas emptying behind the filter dirt.Also can be without the direct emptying of bag dust filter.
