The invention discloses a blowing machine, comprising a box body, a sand blast pipe and a nozzle, wherein an air intake control valve and an exhaust control valve are arranged on the box body, a butterfly-shaped sand adjusting valve is installed at a sand outlet in the bottom of the box body, one end of the sand blast pipe is connected with the box body through the air intake control valve, and the other end of the sand blast pipe is connected with the butterfly-shaped sand adjusting valve and the nozzle through a thickened sand discharge tee. Under the propulsion of air pressure, a grinding material in the box body arrives at height of the thickened sand discharge tee through an inclined internal structure of the butterfly-shaped sand adjusting valve, the thickened sand discharge tee and the butterfly-shaped sand adjusting valve are singly arranged, and the thickened sand discharge tee is improved on increasing the wall thickness of the bottom of the thickened sand discharge tee, so that the attrition time is prolonged, meanwhile a sand dropping opening in the tee is changed from the original 90 degrees into an inclination angle of 45 degrees to form an airflow path with latter airflow in the same direction, so that the effective power of particles in a sand valve is increased, the bounce and convolution of the sand particles at the bottom of the sand valve are reduced, the attrition of the sand discharge tee and the sand blast pipe are reduced and the utilization rate of the blowing machine is increased.
Description
Technical field
The present invention relates to machinery production field, specifically refer to blowing machine.
Background technology
The structural principle of sand-blasting machine make use of the surface that compressed air is transported to sand powder particles the object treating ash propel polish from the sand tank of equipment, and this processing procedure is just referred to as sandblasting, and Main Function is the roughened state improving body surface.Determine that the crucial emphasis of sand spray machine sand spray effect is: suitable sand flow amount and suitable compressed air require.Compressed-air actuated size determines the sinking speed that velocity in pipes size should be greater than the maximum sandy mobile process of sand-blasting machine, and air force is enough to frictional dissipation and the resistance summation of sand grains in control piper, just can ensure sand material smooth outflow in sand-blasting machine pipe; If pipeline is long, sand flow amount is excessive, and compressing pressure of taking a chance will decline, air velocity slows down, and sand grains just there will be the uneven state of suspension, even there will be the situation of part sand material deposition BOP, once sand grains blocks pipeline, sand-blasting machine is directly caused to work on.
Summary of the invention
The present invention, by arranging blowing machine, solves the problem that traditional sand grains easily blocks blast tube, reaches the object improving ash propel polish efficiency.
Object of the present invention reaches by the following technical programs:
The present invention includes casing, blast tube and nozzle, described casing is provided with air intake control valve and gas exhausting valve, the sand export place of bottom half is provided with butterfly and adjusts sand valve, one end of blast tube is connected with casing by air intake control valve, and the other end is shaked out by thickening, and threeway adjusts sand valve with butterfly respectively, nozzle is connected.Outside source of the gas is connected on air intake control valve, start to ventilate in casing, when case internal gas pressure acquires a certain degree, the butterfly simultaneously opening bottom half adjusts sand valve, the abrasive material in case is made to shake out three-way flow to blast tube by thickening under the effect that pressure is large, from shower nozzle ejection under the drive of gas, act on workpiece; Traditional bottom half is not provided with to be adjusted sand valve or adjusts sand valve and shake out overall between threeway being connected, because sand grains is meticulous or equipment does not use the phenomenon that in the tune sand valve that causes, glue core hardens for a long time, is easy to cause blast tube to block;
Adjust sand valve by arranging butterfly at the sand export place of bottom half, butterfly valve adopts inclination to shake out, and overcomes the resistance that the vertical knockout of normal sands valve brings, and sandpipe easily blocks up the feature of sand, is applicable to the use of fine sand; Abrasive material in case is under the promotion of air pressure, adjust the internal structure of sand valve to arrive thickening by the butterfly tilted to shake out threeway, shake out threeway and butterfly of thickening adjusts sand valve to arrange separately, and it is improved and increases bottom wall thickness, increase wearing-in period, the husky mouth that falls in threeway is vertically changed into 45 degree of oblique angles by original 90 degree simultaneously, object forms an air flow path in the same way with tail air-flow, increase the effective power of particle in sand valve, reduce the bounce-back of sand grains bottom sand valve and convolution, reduce the wearing and tearing to shake out threeway and blast tube, strengthen the utilization rate of equipment.
Further, also nozzle connection is provided with between described nozzle and blast tube.According to the difference in size of the polishing area of workpiece, the nozzle of different sandblasting power can be adopted to process, but in general equipment, nozzle and blast tube whole installation, can only carry out workpiece polishing with fixing sandblasting efficiency, cannot satisfy the demands; By arranging nozzle connection, nozzle connection is fixedly connected on blast tube, and nozzle connection is threaded with blast tube, can change nozzle at any time, improve practicality according to actual conditions.
Further, the junction of described air intake control valve and external air source is also provided with filter.When outside air enters in casing, in air, be mingled with the impurity such as a large amount of steam or particle, by easily causing valve body rust corrosion or blast tube inwall damaged when each valve body and blast tube; The filter arranged can be isolated before impurity enters into air intake control valve to be cleaned out, and ensures the drying of source of the gas and effectively carrying out of sandblasting procedures.
Further, also comprise the observation panel be arranged in the middle part of casing, described observation panel is provided with safety glass.Abrasive material in casing can sharply reduce in using for a long time, operating personnel are not when stopping polishing to check that whether amount of abrasive is sufficient, in polishing process, easily occur the situation without sand or few sand, the generation of this kind of situation often causes the idle running of equipment, reduces operating efficiency; One observation panel is set in the middle and lower part of casing, the surplus of abrasive material can be checked for operating personnel at any time, conveniently add abrasive material in time, ensure sandblasting efficiency.
Further, as preferably, described butterfly adjusts sand valve to be that type hand adjusts sand valve.According to the sandblasting situation of reality, manual adjustments can adjust sand valve, control the eliminating of abrasive material flexibly.
The present invention compared with prior art, there is following advantage and beneficial effect:
1, the present invention includes casing, blast tube and nozzle, described casing is provided with air intake control valve and gas exhausting valve, the sand export place of bottom half is provided with butterfly and adjusts sand valve, one end of blast tube is connected with casing by air intake control valve, and the other end is shaked out by thickening, and threeway adjusts sand valve with butterfly respectively, nozzle is connected.Adjust sand valve by arranging butterfly at the sand export place of bottom half, butterfly valve adopts inclination to shake out, and overcomes the resistance that the vertical knockout of normal sands valve brings, and sandpipe easily blocks up the feature of sand, is applicable to the use of fine sand;
2, the junction of air intake control valve of the present invention and external air source is also provided with filter, can be isolated and clean out before impurity enters into air intake control valve, ensures the drying of source of the gas and effectively carrying out of sandblasting procedures.
