Abstract
The utility model relates to an automatically-controlled anti-clogging device of a front mixing type abrasive jet system. The utility model comprises a material pot, an upper cover and a lower cover thereof, a four-way, a three-way and a pipeline, wherein a hydraulic control valve is arranged on an outlet pipeline of the lower cover of the material pot, and a water inlet of a liquid cylinder of the hydraulic control valve is communicated with a high-pressure water inlet pipeline through the three-way. The utility model can automatically close the hydraulic control valve to stop supplying abrasive at the front stage of system boost and the back stage of discharging and planting, the system is rinsed by clear water, and therefore, the pipeline can be prevented from clogging.
Description
Technical field:
The utility model relates to a kind of front mixing abrasive jet stream system, particularly a kind of front mixing abrasive jet stream system automatic control anti-block apparatus.
Background technology:
In the prior art, the front mixing abrasive jet stream system is boosting and is unloading in the whole process, and abrasive feeding changes with slurry velocity in pipes speed, but abrasive material never is interrupted.After system unloading is out of service, residual fraction abrasive material still in the slurry pipe.Restart operation when system like this, when new slurry flow through and, this part residual slurry directly added operation, and pulp density is increased, very easily in pipeline, result in blockage, and especially when system's feeding abrasive material amount is big, easier resulting in blockage.
The utility model content:
The purpose of this utility model is to provide a kind of front mixing abrasive jet stream system automatic control anti-block apparatus, in case the locking system line clogging.
For achieving the above object, the utility model adopts following design: in batch can lower cover exit, settle a hydraulic type control valve, utilize the hydraulic pressure of system itself to control its action: when system water is forced down 1/2-2/3 in specified hydraulic pressure, close, promptly cut off abrasive material and inject to system; When surpassing the 1/2-2/3 of specified hydraulic pressure, open, promptly inject abrasive material to system.Like this, when system's hydraulic pressure did not reach the 1/2-2/3 of specified hydraulic pressure, what flow in the slurry stream pipe was clear water, can wash pipeline earlier, after hydraulic pressure is raised to control valve and opens, had reached certain flow rate in the pipe, and abrasive material adds and is difficult for resulting in blockage.Unloading quits work when system, and hydraulic pressure is less than the control valve opening pressure, and slurry flows out and is closed, abrasive material is cut off, but this moment, system still had certain pressure, still had the clear water of certain flow rate in the pipeline, the abrasive material that remains in the slurry pipe all can be gone out clearly, guarantee that next time, operation did not cause line clogging.
According to above-mentioned design, the utility model adopts following technical proposals: a kind of front mixing abrasive jet stream system automatic control anti-block apparatus, comprise batch can and upper and lower covers thereof, four-way, threeway and pipeline, it is characterized in that on the outlet conduit of batch can lower cover a hydraulic type control valve being housed, the fluid cylinder water inlet of hydraulic type control valve is communicated with the high-pressure intake pipe road by threeway.
The structure of above-mentioned hydraulic type control valve can be designed as: body cavity is settled piston, spring and pressing plate, and pressing plate is supported by an adjustment screw, and adjustment screw is screwed in the valve body upper end wall and is tightened up by nut; The piston rod of piston extends to and constitutes the pipe joint switch in the pipe joint of valve body lower portion, and pipe joint is connected with batch can lower cover outlet conduit.
Above-mentioned pipe connecting structure can be designed as: the loam cake of batch can connects a four-way by pipeline, and the pipeline of leading up to of this four-way connects the import of batch can lower cover, and the pipeline of leading up to connects a threeway, and the pipeline of leading up to connects another threeway; The pipe joint of the hydraulic type control valve bottom on the one connecting pipe road of the former threeway, the pipeline of leading up to connects abrasive jet; The pipeline of leading up to of latter's threeway connects water pump, and the pipeline of leading up to connects the fluid cylinder of hydraulic type control valve.
The utility model compared with prior art, have conspicuous following characteristics and advantage: the utility model is settled a hydraulic type control valve in batch can lower cover exit, the after-stage of the last stage of boosting in system and system's unloading is closed automatically and is stopped feeding abrasive material, system is washed by clear water, then can prevent line clogging.
