A kind of adobe moisture control device
Technical field
The utility model relates to a kind of parameter control device of adobe, is specifically related to adobe moisture control device.
Background technology
The adobe water content is the parameter of the strict control of need.By technological requirement, adobe moisture should be controlled between 14% to 14.5%.Hypohydration can make adobe blocked up; Moisture is excessive, and then adobe is too soft, produces the adobe slabbing.Outward appearance and quality that these all can influence brick cause waste product.For this reason, should strict control amount of water in base soil whipping process, its purpose also has the purpose of others except above factor, and too much as amount of water, base soil is easy to tie the storehouse, can't discharging, production can not normally be carried out.The moisture of brick production line control at present all is to adopt Artificial Control mostly, does not often reach requirement.Base soil moisture was controlled the adding water yield after patent CN201366751 employing was measured and stirred, but this control method does not detect the quality that enters agitator base soil, therefore can not overcome the influence of base soil property amount fluctuation; Simultaneously, this control scheme belongs to the control that lags behind, and always has certain hysteresis quality.Need to develop for this reason and a kind ofly can overcome base soil property amount fluctuation patent again the device that the adobe water content is controlled in advance.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of adobe moisture control device, can control the moisture of base soil before adobe slitting and moulding, and the moisture that can guarantee adobe within limits.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of adobe moisture control device comprises
Microwave moisture detector 6 is used for monitoring the moisture of waiting to stir base soil, and its signal output part is connected with the signal input part of processor 4;
Load transducer 8 is used for detecting the quality of base soil to be stirred, and its signal output part is connected with the signal input part of processor 4;
Processor 4 according to detected moisture signal and the base soil property amount signal of waiting to stir base soil, determines to add the flow of entry, and then output regulation signal;
Control valve 3 is arranged in filler pipe road 2, regulates the flow that adds entry according to the output regulation signal that receives from processor 4.
Described processor 4 is a personal computer, and microwave moisture detector 6 is installed in the top of the base soil conveyer belt 7 before the mixer 1, and load transducer 8 is installed in the below of base soil conveyer belt 7.
The utility model has compared with prior art been realized the leading control to the adobe water content, has guaranteed the moisture of adobe, has overcome the fluctuation of clothes base soil property amount simultaneously again.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in drawings, the present invention is a kind of adobe moisture control device, comprising:
Microwave moisture detector 6 is used for monitoring the moisture of waiting to stir base soil, and its signal output part is connected with the signal input part of processor 4;
Load transducer 8 is used for detecting the quality of base soil to be stirred, and its signal output part is connected with the signal input part of processor 4;
Processor 4 according to detected moisture signal and the base soil property amount signal of waiting to stir base soil, determines to add the flow of entry, and then output regulation signal;
Control valve 3 is arranged in filler pipe road 2, regulates the flow that adds entry according to the output regulation signal that receives from processor 4.
Described processor 4 is a personal computer, and microwave moisture detector 6 models are UM-100, and load transducer 8 is the ICS-30 electronic belt scale.
During use, microwave moisture detector 6 is installed in the top of the base soil conveyer belt 7 before the mixer 1, be used for detecting the moisture of the base soil of continuous mixer 1 inlet 5, microwave moisture detector 6 sends detected signal to computer 4, load transducer 8 is installed in the conveyer belt below, sends computer 4 to the base soil property amount at detection inlet 5 places and with signal.Computer 4 goes out the aperture of control valve 3 and exports control signal to control valve 3 according to the wait water content and the Mass Calculation that stir base soil that detect; Control valve 3 is installed in the filler pipe road 2, changes the aperture of valve and then the discharge that change joins mixer 1 after control valve 3 receives signal, thereby the moisture of base soil is adjusted within certain scope, and then guaranteed the moisture of adobe.
