Description
Technical field
The utility model relates to a kind of vacuum system self-draining arrangement.
Background technology
The need of production of expanded explosive carries out under vacuum environment, utilize vavuum pump to contain a large amount of water vapours in Bulking tank and vacuum device for discharging, lower boiling oil phase material (the complex wax of part, machine oil) and the material such as a little explosive micro mist dirt extract out, these materials are at the surge tank bottom precipitation or under condensing, in these coagulations, be mainly water, when coagulation runs up to a certain degree, the manually-operated gate that must open the buffer bottom carries out draining, must first stop vavuum pump during draining, making to produce in pipeline becomes normal pressure, open again the manual drainage valve, valve-off after drained coagulation, open vavuum pump and carry out operation, to produce the production status that pipeline recovers vacuum.When draining and coagulation, owing to unloading vacuum, production line need stop producing, and has affected continuity and the production efficiency of producing; In addition, the manually opened water discharging valve of special messenger need to be arranged, increase operative employee's additional workload.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of vacuum system self-draining arrangement.
The utility model adopts following technical scheme:
The utility model comprises surge tank, the vavuum pump be connected with surge tank, is arranged on the drainpipe of surge tank bottom and is arranged on the pipeline be connected with production line on surge tank, the drainpipe other end is connected with water tank, described water tank is provided with tapping pipe, described drainpipe is provided with drain solenoid valve, described tapping pipe is provided with the sluicing magnetic valve, and described drain solenoid valve is connected with Programmable Logic Controller by auxiliary reclay with the sluicing magnetic valve.
Described water tank is provided with backing vacuum pump.
The utility model good effect is as follows:
The utility model increases water tank at the original production System drainage mouth of pipe, can produce under the vacuum environment of pipeline not affecting vacuum, timing automaticly completes water and coagulative excretion, not breaks in production operation, reduce operation manually, improve the stability of system vacuum, enhance productivity.
Install independent vavuum pump additional on water tank, can avoid the gas in water tank being communicated to when vacuum is produced pipeline the vacuum environment that affects the production pipeline, the air pressure of vacuum environment is constant can guarantee throughput rate and product quality.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model control flow chart;
In the accompanying drawings: 1 surge tank, 2 vavuum pumps, 3 drainpipes, 4 pipelines, 5 water tanks, 6 tapping pipes, 7 drain solenoid valves, 8 sluicing magnetic valves, 11 backing vacuum pumps.
The specific embodiment
As shown in Figure 1, the utility model comprises surge tank 1, the vavuum pump 2 be connected with surge tank 1, is arranged on the drainpipe 3 of surge tank 1 bottom and is arranged on the pipeline 4 be connected with production line on surge tank 1, drainpipe 3 other ends are connected with water tank 5, described water tank 5 is provided with tapping pipe 6, described drainpipe 3 is provided with drain solenoid valve 7, described tapping pipe 6 is provided with sluicing magnetic valve 8, described drain solenoid valve 7 is connected with Programmable Logic Controller by auxiliary reclay with sluicing magnetic valve 8, and described water tank 5 is provided with backing vacuum pump 11.
In the utility model:
The model of Programmable Logic Controller (PLC) can be: the FX of Mitsubishi
3u-48MR;
The model of drain solenoid valve 7 and sluicing magnetic valve 8 can be: the huge good JLQ941F-16P in Shanghai;
The model of auxiliary reclay can be: Omron MY2NJ.
The utility model drainage frequency can be arranged according to production capacity, as shown in Figure 2, treat in used time water tank 5 vacant for normal pressure, drain solenoid valve 7 and sluicing magnetic valve 8 are all in closed condition, when needing draining, Programmable Logic Controller sends the first auxiliary reclay work that signal controlling drain solenoid valve 7 is opened, drain solenoid valve 7 is opened, the vavuum pump 2 that air in water tank 5 can be produced in pipeline is discharged to outside system, water in surge tank 1 and coagulation can flow in water tank 5 by drainpipe 3, the time that drain solenoid valve 7 is opened can be set as 1 minute, until during setting-up time, Programmable Logic Controller sends the second auxiliary reclay work that signal controlling drain solenoid valve 7 is closed, drain solenoid valve 7 is closed, then Programmable Logic Controller sends the 3rd auxiliary reclay work that signal controlling sluicing magnetic valve 8 is opened, water and coagulation that sluicing magnetic valve 8 is opened in water tank 5 pass through tapping pipe 6 discharge systems, now because drain solenoid valve 7 is closed, can't affect the vacuum state of producing in pipeline, after sluicing magnetic valve 8 arrives setting-up time, Programmable Logic Controller sends the 4th auxiliary reclay work that signal controlling sluicing magnetic valve 8 cuts out, sluicing magnetic valve 8 cuts out, get back to dormant state, Programmable Logic Controller sends the interval time of signal and can set according to actual conditions.
Further improve this technical scheme, can on water tank 5, fill a backing vacuum pump 11, backing vacuum pump 11 carries out work when water tank 5 is got back to dormant state, make water tank 5 reach vacuum, the vacuum of producing in pipeline when drain solenoid valve 7 is opened like this will be stablized, avoid instantaneous boosting, backing vacuum pump 11 also can pass through Controlled by Programmable Controller.
Further improve this technical scheme, can be at the interior installation water level inductor of surge tank 1, when water level arrives desired location, Programmable Logic Controller starts the draining action.
Aborning, limitation due to site space, the position of water tank 5 can't be arranged on below the bottom surface of surge tank 1, water in system and coagulation can't flow into water tank 5 voluntarily, can on drainpipe 3, add holding water pump for this reason, come water and coagulation in completion system to transfer in water tank 5 from surge tank 1, water pump also can pass through Controlled by Programmable Controller, pump working after drain solenoid valve 7 is opened, drain solenoid valve 7 switches off the pump and quits work.
The utility model, under the vacuum environment that does not affect vacuum production pipeline, can timing automaticly complete water and coagulative excretion, and not breaks in production operation reduces operation manually, improves the stability of system vacuum, enhances productivity.
