Description
Technical field
The utility model relates to petroleum pipeline manufacture field, specifically refers to portable sand blasting unit.
Background technology
The structural principle of sand-blasting machine is to have utilized compressed air sand powder particles to be transported to from the sand tank of equipment to the surface of the object for the treatment of ash propel polish, and this processing procedure is just referred to as sandblast, and Main Function is the coarse state that improves body surface.The crucial emphasis that determines sand spray machine sand spray effect is: suitable sand flow amount and suitable compressed air require.Compressed-air actuated size has determined that velocity in pipes size should be greater than the sinking speed of the maximum sand grains flow 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 that in sand-blasting machine pipe, sand material is smooth and easy mobile; If pipeline is long, sand flow amount is excessive, and compressing the pressure of taking a chance will decline, air velocity slows down, and sand grains just there will be the inhomogeneous state of suspension, even there will be the situation of part sand material deposition BOP, once sand grains is blocked pipeline, directly cause sand-blasting machine to work on; And in the time that body carries out gas discharge, on air bleeding valve, can send the comparatively noise of shrillness, affect operating personnel's job schedule.
Utility model content
The utility model is by arranging portable sand blasting unit, solves traditional sand grains and easily block out the problem of sandpipe, reaches the object that improves ash propel polish efficiency.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises body, goes out sandpipe and nozzle, on described body, be provided with intake valve and air bleeding valve, the sand export place of organism bottom is provided with butterfly and adjusts sand valve, the one end that goes out sandpipe is connected with body by intake valve, the other end adjusts sand valve, nozzle to be connected with butterfly respectively by the thickening threeway of shaking out, also comprise the muffler being arranged on air bleeding valve, described organism bottom is also provided with travel mechanism.By travel mechanism, equipment can be pushed into and process arbitrarily place, reduce the labour intensity of Traditional Man carrying; Outside source of the gas is connected on intake valve, start to ventilate in body, in the time that case internal gas pressure acquires a certain degree, open the butterfly of organism bottom simultaneously and adjust sand valve, make the abrasive material in case shake out three-way flow to going out sandpipe by thickening under the large effect of pressure, under the drive of gas, from shower nozzle ejection, act on petroleum pipeline; Traditional organism bottom is not provided with to be adjusted sand valve or adjusts sand valve to be connected with the entirety between threeway of shaking out, and because sand grains is meticulous or equipment does not use the phenomenon that in the tune sand valve causing, glue core hardens for a long time, is easy to cause the blockage that shakes out;
By the sand export place at organism bottom, butterfly is set and adjusts sand valve, butterfly valve adopts and tilts to shake out, and overcomes the resistance that the vertical knockout of normal sands valve brings, and sandpipe is the feature of stifled sand easily, 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 by the butterfly tilting and thicken the threeway of shaking out, thickening threeway and the butterfly tune sand valve that shakes out arranges separately, and it is improved and increases bottom wall thickness, increase wearing-in period, sand-falling port in threeway is vertically changed into 45 degree oblique angles by 90 original degree simultaneously, object is to form an air flow path in the same way with tail air-flow, increase the effective power of particle in sand valve, reduce bounce-back and the convolution of sand grains in sand valve bottom, reduce the wearing and tearing of shaking out threeway and going out sandpipe, strengthen the utilization rate of equipment; In the time carrying out exhaust, the muffler on air bleeding valve can effectively reduce the noise of generation, safeguards good working environment.
Further, described nozzle and go out to be also provided with nozzle connection between sandpipe.According to the difference in size of the polishing area of petroleum pipeline, can adopt the nozzle of different sandblast power to process, but in general equipment, nozzle with go out sandpipe whole installation, can only carry out petroleum pipeline polishing with the sandblast efficiency of fixing, cannot satisfy the demands; By nozzle connection is set, nozzle connection is fixedly connected on out on sandpipe, and nozzle connection is connected with the gas thread that shakes out, and can change at any time nozzle according to actual conditions, has improved practicality.
Further, the junction of described intake valve and external air source is also provided with filter.In outside air enters into body time, in air, be mingled with a large amount of impurity such as steam or particle, easily causing valve body rust corrosion or shake out inside pipe wall breakage by each valve body with while going out sandpipe; The filter arranging can be cleaned out its isolation before impurity enters into intake valve, ensured being dried of source of the gas and effectively carrying out of sandblast process.
Further, described travel mechanism comprises two castors and leg, and described castor and leg are angular distribution.According to leg-of-mutton stability, in the time that polishing process carries out, the combination of castor and leg can provide stable support and fixed function; When mobile, only body one end need be tilted, promote body, can be under the rolling of castor fast moving sand-blasting machine, reduced workman's working strength.
Further, also comprise the observation panel that is arranged on body middle part, on described observation panel, safety glass is installed.Abrasive material in body can sharply reduce in using for a long time, operating personnel are not in the time stopping polishing and check that amount of abrasive is whether sufficient, easily in polishing process, occur that the idle running that tends to cause equipment of this kind of situation, reduces operating efficiency without sand or the situation of few sand; In the middle and lower part of body, one observation panel is set, the surplus that can check at any time abrasive material for operating personnel, the convenient abrasive material that adds in time, ensures sandblast efficiency.
Further, as preferably, it is that type hand is adjusted sand valve that described butterfly is adjusted sand valve.According to actual sandblast situation, can manual adjustments adjust sand valve, control flexibly the eliminating of abrasive material.
The utility model compared with prior art, there is following advantage and beneficial effect:
1, the utility model comprises body, goes out sandpipe and nozzle, on described body, be provided with intake valve and air bleeding valve, the sand export place of organism bottom is provided with butterfly and adjusts sand valve, the one end that goes out sandpipe is connected with body by intake valve, the other end adjusts sand valve, nozzle to be connected with butterfly respectively by the thickening threeway of shaking out, and also comprises the muffler being arranged on air bleeding valve.By travel mechanism, equipment can be pushed into and process arbitrarily place, reduce the labour intensity of Traditional Man carrying;
2, the junction of intake valve of the present utility model and external air source is also provided with filter, can before impurity enters into intake valve, its isolation be cleaned out, and ensures being dried of source of the gas and effectively carrying out of sandblast process.
