Description
Technical field
The utility model relates to a kind of kiln temperature continuous measuring device.
Background technology
At present, in the production line of pellet, generally adopt chain grate-rotary kiln-central cooler to pellet be dried, preheating, burn till, cooling process route.For the requirement of production process control and product quality, need to rotary kiln middle part temperature be detected and be controlled.Because the rotary kiln adopting now has maximization, be again the equipment of rotatablely moving, to the detection of its middle part temperature, be a large difficult point.Traditional method is to punch on the barrel of rotary kiln middle part, temperature element (thermocouple) is inserted to rotary kiln inner, at the circular conducting bracket of the peripheral installation of rotary kiln barrel, be connected with temperature element, then contact with circular support with slide unit, by temperature signal cut-in temperature transmitter.
The shortcoming of this temperature survey mode is: 1,, along with the carrying out of production process, rotary kiln inwall is ring formation always, and temperature element is buried, and it can not be contacted with rotary kiln internal high temperature flue gas, causes measure error; 2, due to what adopt between the peripheral conducting bracket of installing of rotary kiln barrel and temperature transmitter, be to be slidably connected, slide unit and conducting bracket loose contact, contact resistance is large, and measure error is further expanded.
Utility model content
The technical problem that the utility model solves is to provide a kind of kiln temperature continuous measuring device that can measure accurately for a long time rotary kiln temperature.
The utility model solves the technical scheme that its technical problem adopts: kiln temperature continuous measuring device, comprise rotary kiln, rotary kiln comprises charging aperture and discharging opening, on the barrel of rotary kiln, have peep hole, the arranged outside of peep hole has infrared radiation thermometer, infrared radiation thermometer is connected with signal adapter, and signal adapter is connected with PLC, and PLC is connected with display.
Further: peep hole and charging aperture are separately positioned on the two ends of rotary kiln.
Further: infrared radiation thermometer and signal adapter are all arranged on movable stand, movable stand bottom is provided with walking mechanism, and PLC and display are all arranged in control room.
The beneficial effects of the utility model are: can measure accurately for a long time rotary kiln temperature.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of kiln temperature continuous measuring device of the present utility model;
In figure, be labeled as: charging aperture--1, discharging opening--2, barrel--3, infrared radiation thermometer--4, signal adapter--5, PLC--6, display--7, rotary kiln--8, peep hole--9, point for measuring temperature--10.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, kiln temperature continuous measuring device, comprise rotary kiln 8, rotary kiln 8 comprises charging aperture 1 and discharging opening 2, on the barrel 3 of rotary kiln 8, have peep hole 9, the arranged outside of peep hole 9 has infrared radiation thermometer 4, and infrared radiation thermometer 4 is connected with signal adapter 5, signal adapter 5 and PLC(programmable logic controller (PLC)) be connected, PLC is connected with display 7.Infrared radiation thermometer 4 can obtain the temperature in rotary kiln 8 by peep hole 9, and infrared radiation thermometer 4 can show by signal adapter 5 and PLC the temperature signal of acquisition on display.
On the basis of the above, in order to reduce the impact of the interior material of rotary kiln 8 on peep hole 9, further improve the accuracy of thermometric, as shown in Figure 1, peep hole 9 and charging aperture 1 are separately positioned on the two ends of rotary kiln 8, namely the axial two ends of rotary kiln 8.Rotary kiln 8 is when work, and the interior material of rotary kiln 8 can not have a negative impact to above-mentioned peep hole 9 substantially.
Above-mentioned infrared radiation thermometer 4, signal adapter 5, PLC6 and display 7 can be arranged on fixed mount.For the ease of arranging, move, control and maintenance, infrared radiation thermometer 4 and signal adapter 5 are all arranged on movable stand, and movable stand bottom is provided with walking mechanism, and PLC and display 7 are all arranged in control room.Walking mechanism can be the mechanisms such as dolly.
