Abstract
The utility model provides an automatic reflux unit of emulsion explosive semi-manufactured goods, relates to emulsion explosive preparation technical field, and its structure is: hopper below is provided with three discharging pipes, is connected through flange A between discharging pipe and the screw pump, and the reduction gear is connected to screw pump one end, and the reduction gear is connected with the output shaft of motor, and the output of screw pump passes through flange B to be connected with the conveying pipeline, and the back flow is connected to the vertical direction of conveying pipeline, and the back flow lower extreme passes through ring flange A to be connected with pressure switch, the back flow upper end is the U type, and U type opening is in the hopper top, connects pressure sensor on the conveying pipeline of back flow joint front end, and pressure sensor control connection pressure switch. The beneficial effects of the utility model reside in that: by adopting the backflow device and utilizing the combined use of the pressure sensor and the pressure switch, when blockage or machine failure occurs, the pressure switch is automatically opened, so that the material flows back to the hopper, and the damage of the pump and the leakage of the material are prevented.
Description
Technical Field
The utility model relates to a technical field of emulsion explosive preparation especially relates to an automatic reflux unit of emulsion explosive semi-manufactured goods.
Background
At present, the emulsion explosive semi-manufactured goods adopt 3 sets of screw pumps to connect the hopper lower extreme when carrying the charge machine to and carry, nevertheless because the emulsion explosive material is thick, and mobility is poor, the emulsion explosive can take place to block up in production packaging transportation process, or when packaging machine stopped or the trouble, the pump was not in time closed, leads to the pump to damage or the material leaks, so not only reduces work efficiency, still damages the pump, causes the production accident.
Disclosure of Invention
To the above problem, the utility model provides an automatic reflux unit of emulsion explosive semi-manufactured goods, its structure is: 1 below of hopper is provided with three discharging pipes 7, is connected through flange A8 between discharging pipe 7 and the screw pump 9, and reduction gear 10 is connected to screw pump 9 one end, and reduction gear 10 is connected with motor 11's output shaft 12, and the output of screw pump 9 passes through flange B13 to be connected with conveying pipeline 6, and return pipe 2 is connected to the vertical direction of conveying pipeline 6, and 2 lower extremes of return pipe pass through ring flange A3 and be connected with pressure switch 4, 2 upper ends of return pipe are the U type, and U type opening is in hopper 1 top, flows back to in the hopper 1, connects pressure sensor 5 on the conveying pipeline 6 of 2 joint front ends of return pipe, is provided with the manometer on pressure sensor 5.
The utility model discloses a principle and application method: the utility model provides an automatic reflux unit of emulsion explosive semi-manufactured goods, sets for certain value on pressure switch, and pressure sensor and pressure switch's control are connected, make equipment form reflux unit, and when using, set for and be in pressure switch upper limit value, start the screw pump, when the conveying pipeline takes place to block up or next equipment trouble, pressure sensor opens automatically when reaching the upper limit value of setting for, flows to the hopper through the return line.
The beneficial effects of the utility model reside in that: the utility model discloses a reflux unit utilizes pressure sensor and pressure switch's combination to use, and when taking place to block up or machine trouble, pressure switch is automatic to be opened, makes the material flow back to the hopper in, strives for a lot of time for closing pump and preceding production line machine, has prevented the damage of pump and the leakage of material, the utility model discloses simple structure can use widely.
