Abstract
The utility model discloses a kind of Pulverized Coal Bin material level and temperature-detecting device, and the cross section home position of described Pulverized Coal Bin arranges the thermometric pipeline axially from Pulverized Coal Bin bottom to top; Be full of thermometric liquid in described thermometric pipeline, the top set temperature transmitter of described thermometric pipeline, described temperature transmitter is connected with host computer; The both sides of described Pulverized Coal Bin arrange boss, and described boss corresponding position arranges LOAD CELLS; Described temperature transmitter is 2; Described LOAD CELLS is 2.The utility model has the advantages that: overcome because coal dust in storehouse moves down and cause the disadvantage of the fracture of temperature sensor and level-sensing device.This programme also can gather around in starch factory, cement mill, etc. in powder manufacturing apparatus system.
Description
Technical field
The utility model relates to detection technique field, is a kind of material level and temperature-detecting device specifically.
Background technology
In Pulverized Coal Bin, often need to detect material level and temperature, existing detection method as shown in Figure 2, upper in Pulverized Coal Bin 2, in, bottom is set temperature sensor 11 and level sensor 12 respectively, because the discharging opening 9 of Pulverized Coal Bin is in bottom, in use, coal dust can outwards export from discharging opening 9 by discharging motor 8, coal dust is caused to move down from Pulverized Coal Bin top, this moves and easily causes temperature sensor and level sensor to damage, this have impact on the accurate acquisition of temperature and level signals on the one hand, more seriously temperature sensor and level sensor break, and part is direct to enter to powder equipment with coal dust, cause to the damage of powder equipment.
Summary of the invention
For solving the problems of the technologies described above, the utility model discloses a kind of material level and temperature-detecting device, and effectively can overcome temperature sensor and level sensor damage, concrete technical scheme is as follows:
A kind of Pulverized Coal Bin material level and temperature-detecting device, is characterized in that: the cross section home position of described Pulverized Coal Bin arranges the thermometric pipeline axially from Pulverized Coal Bin bottom to top; Be full of thermometric liquid in described thermometric pipeline, the top set temperature transmitter of described thermometric pipeline, described temperature transmitter is connected with host computer; The both sides of described Pulverized Coal Bin arrange boss, and described boss corresponding position arranges LOAD CELLS;
For ensureing the accuracy of data, described temperature transmitter is 2; Described LOAD CELLS is 2;
The top of Pulverized Coal Bin arranges venting.
The utility model has the advantages that: overcome because coal dust in storehouse moves down and cause the disadvantage of the fracture of temperature sensor and level-sensing device.] this programme also can gather around in starch factory, cement mill, etc. in powder manufacturing apparatus system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is prior art schematic diagram.
Embodiment
The utility model is illustrated below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises a kind of Pulverized Coal Bin 2, and the cross section home position of described Pulverized Coal Bin 2 arranges the thermometric pipeline 1 axially from Pulverized Coal Bin bottom to top, and the material of described thermometric pipeline can be the metal material such as stainless steel, carbon steel; Be full of thermometric liquid in described thermometric pipeline 1, described thermometric liquid can be anti freezing solution, also can be oils; The top set temperature transmitter 7 of described thermometric pipeline 1, described temperature transmitter 7 is connected with host computer; The both sides of described Pulverized Coal Bin 2 arrange boss 4, and described boss 4 corresponding position arranges LOAD CELLS 3, and described LOAD CELLS is connected with host computer; The bottom of LOAD CELLS 3 arranges fulcrum of weighing, and the top of Pulverized Coal Bin arranges venting 6.
For ensureing the accuracy of data, described temperature transmitter is 2; Described LOAD CELLS is 2.Two temperature transmitter device signals and load cell signal are compared process to realize self-checking function in computing machine.
Temperature detection principle: the coal dust central temperature in Pulverized Coal Bin, the thermometric liquid in pipe is passed to by temperature tube arm, move due on the liquid that temperature is higher, therefore, the maximum temperature of what the temperature transmitter on temperature tube top was collected is Pulverized Coal Bin inside, temperature signal is passed to computer disposal by temperature transmitter.
Material-level measure principle is as follows: with two cover LOAD CELLS alter connection structure weigh up coal dust amount number, and by two cover weighing-up waves send computing machine respectively to, two weight signals compare by computing machine, judge the correctness of two signals.Correct weighing-up wave can realize the consecutive variations of breeze material position in storehouse by computer disposal.Such improvement just overcomes afterwards, causes the disadvantage of the fracture of temperature sensor and level-sensing device because coal dust in storehouse moves down.
