Specific embodiment
Below in conjunction with shown in accompanying drawing 1 to accompanying drawing 4, the utility model is further described by specific embodiment.
A kind of drum up-draft gasifier big device when avoiding that drum boiler is with pressure to discharge water, including drum body 1, drum body
1 top is provided with and is attached thereto logical steam guiding tube 2, the side wall of steam guiding tube 2 pass through two connecting pipes 3 arranging up and down with it is flat
Weighing apparatus container cartridge 14 is connected, and realizes the conducting and cut-off of pipeline on each connecting pipe 3 further through one valve 4 of connection；It is flat
One piece of magnetic slider 5 that can be fluctuated according to the change of water level, equalizing reservoir are placed with the cavity volume of weighing apparatus container cartridge 14
One piece of magnetic flap 6 is installed on the side wall of cylinder 14；Magnetic flap 6 is sequentially arranged by multiple cylinder magnetic sheets and constituted, each
Cylindrical magnetic sheet is made up of the semicolumn magnetic sheet of two different magnetic, is realized by magnetic slider 5 and semicolumn magnetic sheet magnetic coupling
The upset of cylindrical magnetic sheet.Two semicolumn magnetic sheets in cylindrical magnetic sheet are two semicolumn magnetic sheets of different colours, half
It is white, second half is red.
Before to water on drum, upper and lower two valves 4 are slowly opened, when steam water-level is higher, the water in drum will enter
Steam guiding tube 2, when the water level in steam guiding tube 2 is higher than the valve of bottom, water enters equalizing reservoir cylinder by valve and connecting pipe 3
14, the magnetic slider 5 in equalizing reservoir cylinder 14 starts to float, and the circle in magnetic flap 6 will be driven in the floating-upward process of magnetic slider 5
Cylindricality magnetic sheet overturns, so that it becomes red.Conversely, during water level reduction, the water level of the display of magnetic flap 6 will decline, and make cylinder
Magnetic sheet is changed into white.Red and white turnover panel intersection is the water level in equalizing reservoir cylinder 14.As long as keeping the water of drum
When position is between upper valve and bottom valve location, you can confirm that drum fills with water, because water is the good conductor of heat, then
Drum up-draft gasifier will disappear, and boiler is with pressure when discharging water, and drum up-draft gasifier will very little.
The inwall of equalizing reservoir cylinder 14 is uniformly provided with multiple tongue tubes 7 from bottom to up, and each tongue tube is concatenated respectively
One resistance 8, multigroup tongue tube and resistance are connected together, and the resistance value that will be detected by resistance value detector 9 is turned by AD
By signal transmission to controller 11, controller 11 shows level value further through D/A converter 12 parallel operation 10 in display screen 13.
When magnetic slider 5 is located at some tongue tube 7, now, this tongue tube 7 is internal two in the presence of magnetic force
Reed end points attracts each other and closes, so that turning circuit, electricity is measured by the voltmeter and ammeter in resistance value detector 9
After pressure value and current value are computed, the resistance value of gained is passed into controller 11, because the resistance of each tongue tube 7 concatenation
Value it is all different, therefore, total resistance value each time is also differed, therefore, controller 11 by different resistance values by it is right
The liquid level answered is shown by display screen 13.
Using AT89S51 type single-chip microcomputers, this series monolithic is low-power consumption, is programmed with the online classes of 4KB controller 11
The single-chip microcomputer of flash storage, its instruction system and pin compatibility with general 80C51 series monolithics.Flash in piece can
Permission is reprogramed online, it is possible to use programming non-volatile memory, it is integrated by universal cpu and online programmable Flash
On a single die, form it is powerful, use flexibly and microcontroller with superior performance cost performance.Converter 10
Using ADC0809 type converters.D/A converter 12 uses DAC0832 type converters.Display screen 13 uses 12864 liquid crystal displays, should
The screen display advantage of lower cost of dot matrix, it is adaptable to each quasi-instrument, the display field of mini-plant.
Although the utility model, those skilled in the art have shown and described referring particularly to its preferred embodiment
It is appreciated that the various changes that can be made in form and details are new without deviating from this practicality described in appended claims
The scope of type.It is described in detail above in association with specific embodiment of the utility model, but is not to limit of the present utility model
System.It is every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, still fall within this practicality
The scope of new technique scheme.
