The method disclosed by the invention is designed by integrating the requirements for on-line monitoring on the temperature of the cylindrical wall of the cylinder dryer in the tobacco industry; and by using the method, the on-line monitoring on the temperature of the cylindrical wall of a cylinder dryer can be implemented, and the temperature data can be recorded, sorted and analyzed in real time, thereby intuitively learning the temperature distribution state of the cylindrical wall of the dryer. Thus, the method can play a crucial role in controlling the material processing quality of a tobacco production line in the tobacco industry.
Description
Technical field
The present invention relates to the special-purpose machinery thermometry that grows tobacco, mainly relate to the cylinder cut tobacco dryer barrel thermometry that a kind of tobacco business is used.
Background technology
Also do not have direct measuring method for cylinder cut tobacco dryer barrel temperature at present, existing understanding to cylinder cut tobacco dryer barrel temperature is that the data that draw through vapor pressure reduced temperature formula are as the barrel temperature value; Or measure the steam tube wall temperature be connected with its inwall reference value through infrared temperature measurement apparatus as the inner wall of rotary drum temperature.Because the inner special working environment of cylinder cut tobacco dryer: characteristics such as high temperature (environment temperature≤150 ℃), high humidity (quantity of steam is big), inner punishment in advance, coaxial at the uniform velocity rotation; Therefore, use present existing temperature survey mode all can't directly test the actual temperature under the cylinder cut tobacco dryer inwall duty.
Summary of the invention
In view of existing problem in the above-mentioned prior art; The objective of the invention is a kind of novel cylinder cut tobacco dryer barrel thermometry of design studies; But real time on-line monitoring cut-tobacco drier barrel temperature, thereby intuitively understand the barrel temperature distribution state, effective monitoring material crudy.
The objective of the invention is to realize through following technical scheme: cylinder cut tobacco dryer barrel thermometry of the present invention is at cut-tobacco drier inner installation thermopair and data recorder the cut-tobacco drier inwall to be carried out temperature survey; Through placing the inner remote measurement external member of register that the temperature data of register is arrived computing machine through the transmitter transmitted radio signal, carry out temperature analysis then by data processing software; Its concrete job step is following:
A. thermocouple probe is fixed on the cut-tobacco drier inwall heating thin plate, connecting line is connected on the register along barrel and cut-tobacco drier jet chimney;
B. register connects a plurality of thermopair passages, and the temperature data of record thermopair output is saved in the register, and register places in the hot box and is fixed on the pivoted arm of tobacco-dryer exit position, and whole device and cut-tobacco drier cylinder can be rotated synchronously;
C. through the built-in remote measurement external member (transmitter) of register temperature data is transmitted into computing machine, carries out temperature analysis by computer software.It has 10 frequency ranges to select, and can reach 200 meters in the open field transmission range.
Described hot box is made up of the effectively insulating layer, to adapt to cut-tobacco drier inner high temperature, high humidity environment, guarantee register under ℃ condition of environment temperature≤200, stream time 16 hours.
Register and remote measurement external member are by accumulator (Ni-MH battery) power supply, and power-on time is 130 hours continuously under the temperature measuring equipment normal operating conditions.
Confirm that according to cut-tobacco drier internal heat units quantity the thermocouple assay point is provided with quantity, a register connects, stores 8-10 thermopair passage.Each register can store 130,000 readings through 8 or 10 optional passages, and test point excessive amount (more than 10) can be selected two groups of proving installations for use.
Method of testing of the present invention is comprehensive tobacco business cylinder cut tobacco dryer barrel on-line temperature monitoring requirement and designing, and is made up of a programmable data register, thermopair, hot box and temperature analysis software.Can carry out on-line monitoring to cylinder cut tobacco dryer barrel temperature through the present invention, and can write down, put in order and analyze temperature data in real time, thereby intuitively recognize cut-tobacco drier barrel temperature distribution state.This controls tobacco business throwing line material crudy and plays crucial effects.
