Abstract
An automatic vacuum maintain device of the utility model belongs to the field of vacuum boiler. The utility model is suitable for vacuum boiler. The main technology of the utility model is as follows: a gas collecting tank is installed on a furnace shell of a heat exchanging chamber of the vacuum boiler; a heat sensor is installed on the gas collecting tank; a heat sensor is installed on a water jacket shell of the vacuum boiler; a heat sensor on the gas collecting tank and the heat sensor on the water jacket shell have a lead connected with a controller; the control has a lead connected with a vacuum pump and a lead connected with an electromagnetic valve; a pipe is installed between the electromagnetic valve and the gas collecting tank; the pipe is provided with a check valve; the vacuum pump has a pipe connected with the electromagnetic valve; the vacuum pump is provided with an exhaust pipe. The favourable effects of the utility model are as follows: the vacuum can be automatically pumped according to the actual operating condition of the vacuum boiler to ensure the stability of the vacuum degree and thereby improving the operating efficiency of the vacuum boiler and saving resource.
Description
One: technical field:
The utility model belongs to the vacuum boiler field.
Two: background technology:
The key technology of vacuum boiler is a vacuum, and vacuum can stable for extended periods of time, Here it is good vacuum boiler.The ruined reason of vacuum boiler vacuum has: boiler produces seepage because of workmanship; The secondth, heat medium water and body of heater steel plate generation chemical reaction discharge a kind of incoagulable gas, i.e. hydrogen, and incoagulable gas will directly influence the vacuum of vacuum boiler.The incoagulable gas mass content reaches at 1% o'clock, and condensation heat of transformation efficient reduces by 60%, and leaving water temperature does not increase, and reduces boiler output.So during the vacuum boiler operation, must extract incoagulable gas out and go.Present vacuum boiler adopts rotary-vane vaccum pump to vacuumize.This vacuumizing can only be moved under cold conditions, can't realize the content of incoagulable gas in the online detection stove, and whether automatic vacuum needs to rely on artificial judgement to need to vacuumize, and the vacuum in can't the real-time ensuring stove is so will improve it.
Three: technology contents:
The purpose of this utility model is exactly to design a kind of automatic holdout device of vacuum of the practical operation situation automatic vacuum according to vacuum boiler.
The technical scheme that the utility model technical solution problem is adopted is: adorn an air collector on the furnace shell of the heat-exchanging chamber of vacuum boiler, heat sensor is housed on the air collector, on the water jacket shell of vacuum boiler, adorn a heat sensor, heat sensor on the air collector all has lead to be connected with controller with heat sensor on the water jacket shell, there is lead to be connected on the controller with vavuum pump 9, there is lead to be connected with magnetic valve, between magnetic valve and the air collector pipe is housed, check-valves is housed on the pipe, there is pipe to be connected on the vavuum pump, blast pipe is housed on the vavuum pump with magnetic valve.
The beneficial effects of the utility model are: can be according to the actual conditions of vacuum boiler operation, and automatic vacuum guarantees the stable of vacuum, thereby has improved the vacuum boiler operational efficiency, has saved the energy.
Four: description of drawings:
Fig. 1 is a system architecture schematic diagram of the present utility model.
Five: the specific embodiment:
Describe the utility model details and working condition in detail in conjunction with Fig. 1.On the furnace shell 1 of the heat-exchanging chamber 3 of vacuum boiler, adorn an air collector 4, heat sensor 5 is housed on the air collector, on the water jacket shell 16 of vacuum boiler, adorn a heat sensor 6, heat sensor 5 on the air collector all has lead 11 to be connected with controller 10 with heat sensor 6 on the water jacket shell, there is lead 15 to be connected on the controller with vavuum pump 9, there is lead 13 to be connected with magnetic valve 8, pipe 12 is housed between magnetic valve 8 and the air collector 4, check-valves 7 is housed on the pipe, there is pipe 12 to be connected on the vavuum pump 9, blast pipe 14 is housed on the vavuum pump 9 with magnetic valve 8.Heat sensor 5 spreads out of the temperature of air collector 4, and heat sensor 6 spreads out of the temperature on the water jacket shell 16, and these two temperature are different high, and this is the reason owing to incoagulable gas.When incoagulable gas gathers 4 li of air collectors gradually, because incoagulable gas does not participate in heat exchange, so the temperature of air collector slowly descends, temperature when air collector temperature and heat medium water, just the temperature of heat sensor 6 differs when falling the certain value, ordinary circumstance is 10 when spending, and controller 10 will be assigned instruction, makes vavuum pump 9 runnings, promptly vacuumize, magnetic valve 8 is opened, and after incoagulable gas was taken away, negative pressure steam arrived air collector, the air collector temperature rises, the temperature difference diminishes, and controller is assigned instruction and stopped to vacuumize, and so just can keep the vacuum of vacuum boiler and move within the specific limits.
