Description
Technical field
The present invention relates to the testing equipment fields of fired brick, detect particularly for the calcium oxide in sintered brick of building construction
Device.
Background technique
For generally can all contain calcium carbonate in the raw material of the fired brick of building construction, when fired brick fire when,
Calcium carbonate can be generated calcium oxide by thermal response.When in use, internal calcium oxide can steam fired brick with the water in air
Solid/liquid/gas reactions generate calcium hydroxide, and volume expands, and explosion destruction occurs so as to cause the overall structure of fired brick, into
And security risk is caused to building.Then, the detection of the calcium oxide of fired brick is mainly reacted by Decrepitation Phenomena.It is examining
When survey, fired brick is subjected to boiling, the inside for making vapor enter fired brick is reacted with calcium oxide, to make fired brick
Decrepitation Phenomena occurs, then the explosion region on fired brick is counted, and then reflect the feelings of the calcium oxide in fired brick
Condition.When being detected, it will use to a boiling case, same group of fired brick for being used to detect be spaced apart in the case, case
The lower part of body is equipped with sink and heating mechanism, after the lid for covering cabinet, is heated by heating mechanism to water and generates vapor, made
Fired brick is in water vapor atmosphere, after the boiling of certain time, is taken out fired brick and is carried out the statistics in bursting area domain, into
And obtain testing result.Since when detecting to fired brick, the quantity of sampling quantity of fired brick is generally all bigger, and burns
The weight for tying brick itself is also bigger, and then, testing staff can generate in the detection for being sintered brick and largely move sintering
The movement of brick causes a large amount of work load to testing staff.
Summary of the invention
The invention is intended to provide a kind of detection device for calcium oxide in sintered brick for building construction, to solve the prior art
For middle fired brick when detecting calcium oxide, the workload that testing staff moves fired brick is bigger, causes work load larger

Fired brick weight, then feed support plate and discharging support plate realized under the action of the gravitational difference of fired brick charging branch
The automatic of support plate that move up and discharge automatically of fagging moves down, no setting is required additional power mechanism, has saved the energy, has simplified
The structure of device.
Further, the charging support plate includes the movable plate of at least two pieces of separate types setting, is set between adjacent movable plate
There is telescopic gas storage mechanism, telescopic gas storage mechanism is connected to the inside of boiling case.By the way that movable plate is arranged, make one block of fired brick
Corresponding one piece of movable plate is placed, and by being located remotely from each other for movable plate, may be implemented the distance between fired brick adjusting increase, from
And meet the requirement of detection；By the way that the telescopic gas storage mechanism being connected to boiling case, the vapor generated when using boiling is arranged
Push telescopic gas storage mechanism to extend, so that adjacent movable plate be pushed to be located remotely from each other, and then reach between adjustment fired brick away from
From purpose, no setting is required additional power mechanism realizes the operation, saved the energy.
Further, the telescopic gas storage mechanism is elastic bellows.The material of elastic bellows is easier to obtain, from
And facilitate and carry out the operation such as replacing in maintenance, can manufacture reduces cost.
Further, the loading mechanism is that the conveyer mechanism of material is transmitted from feed inlet toward discharge port.It is passed by setting
Dynamic band mechanism, facilitates fired brick transverse shifting in boiling case；By the transmission effect of conveyer belt, make the fired brick of feed inlet can
Automatically to enter in boiling case, the fired brick in boiling case can also be removed automatically from discharge port, alleviate detection
The work load of personnel.
Further, the linkage mechanism is pulley block mechanism, and pulley block mechanism includes hawser, charging support plate and discharging branch
Fagging is fixedly connected with the both ends of hawser respectively.By setting pulley block mechanism as linkage mechanism, linkage mechanism can be made
It is relatively simple for structure, facilitate manufacture.
Further, the upper surface of the movable plate is embedded with several rotatable carrying rollers.By the way that support is arranged on movable plate
Roller facilitates fired brick to move on movable plate, so that fired brick be facilitated to enter in boiling case from movable plate.
