Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to an auxiliary monitoring device for cement kiln burning parameters. Background Art

[0002] Raw materials such as limestone, clay, iron ore, etc. are crushed into appropriate particle sizes, and different types of raw materials are mixed together. The mixed raw materials are sent to the cement kiln for high-temperature calcination. In the cement kiln, the raw materials undergo chemical reactions at high temperatures to form a molten material called clinker.

[0003] Thermocouples play an important role in the process of cement kiln burning. Thermocouples are used to measure the temperature of various parts inside the cement kiln. By monitoring the temperature of different areas, production personnel can understand the temperature distribution of cement clinker in real time during the calcination process.

[0004] There are a lot of chemical substances inside the cement kiln, such as dust, soot, and powder. Various solid particles adhere to the surface of the thermocouple protective cover and gradually deposit to form scaling. Scaling will increase the thermal resistance of the thermocouple outside, reduce the heat conducted from the working medium to the thermocouple, and reduce the actual temperature surface area that the thermocouple contacts, thus affecting the accuracy of temperature measurement. For this reason, we propose a cement kiln firing parameter auxiliary monitoring device to solve the existing problems. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and proposes a cement kiln firing parameter auxiliary monitoring device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary monitoring device for cement kiln firing parameters, comprising a motor, a terminal block, a mounting ring, a screw, a thermode and a sleeve ring, a protective sleeve being inserted into the terminal block, a thermode being arranged inside the protective sleeve, a terminal connected to the opening end of the protective sleeve being arranged at one end of the thermode, a motor being arranged at one end of the terminal block, a screw being arranged at the output end of the motor, a mounting ring being sleeved on the outer side of the protective sleeve, brush strips distributed in a ring array being arranged on the inner wall of the mounting ring, a threaded block being embedded and installed inside the mounting ring, and one end of the screw being rotatably inserted into the threaded block.

[0007] Preferably, the outer side of the thermode is sheathed with an insulating sleeve located inside the protective sleeve. The insulating sleeve effectively isolates the measured medium from the external environment, prevents leakage or short circuit when the thermode contacts the medium, and ensures accurate temperature measurement without being affected by external interference or pollutants.

[0008] Preferably, a fixing ring is sleeved on the outer side of the wiring seat, and the inner wall of the fixing ring is provided with mounting holes distributed in a circular array. The fixing ring is fixed to the mounting base of the cement kiln, and the fixing parts are plugged in through the mounting holes.

[0009] Preferably, the screw rod is rotatably mounted with the wiring seat via a bearing. The screw rod is rotatably mounted inside the wiring seat via a bearing.

[0010] Preferably, a slider is provided at the lower end of the mounting ring, a sliding seat is provided at one end of the wiring seat, the slider is slidably mounted on the outer wall of the sliding seat, and a limiting ring with a radius greater than the inner diameter of the threaded block is provided at one end of the screw. The mounting ring is slidably mounted on the upper end of the sliding seat through the slider, the mounting ring is slidably guided, and the limiting ring prevents the threaded block from completely separating from the screw, and limits the limiting ring.

[0011] Preferably, a connection block is provided at the upper end of the mounting ring, and symmetrically distributed collars are provided at the lower end of the connection block. The collars are all sleeved on the outside of the screw and are located on both sides of the threaded block. The inner wall of the collar is provided with two brush strips distributed in a ring array. The two brush strips on the inner wall of the collar brush away the scale adhered to the outer wall of the screw, and when the threaded block moves, the scale adhered to the outer wall of the screw on the moving path is brushed away.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model sleeves a mounting ring on the outer wall of the thermocouple, and a brush strip is arranged on the inner wall of the mounting ring. By driving the scaling to move laterally on the outer wall of the thermocouple protective sleeve, the brush strip scrapes off the scaling on the outer wall of the thermocouple protective sleeve. There is no need to stop the machine for cleaning. The protective sleeve of the thermocouple can be cleaned in real time and continuously during the continuous operation of the cement kiln, so as to maintain the continuous operation of the production equipment and ensure that the production process is not affected by the cleaning operation. Through regular cleaning, the thermocouple will maintain more accurate and stable temperature measurement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0021] Implementation steps based on Example 1: When the thermocouple's hot electrode 14 contacts the high-temperature area in the cement kiln, a thermoelectric effect will be generated between the two different metals. This thermoelectric effect will cause a small electromotive force to be generated at the joint. By connecting the thermocouple to the terminal 2 of a measuring instrument, the generated small electromotive force can be measured. By converting the measured electromotive force value into a temperature value, the temperature at the location of the thermocouple can be determined. A specially designed rotary joint assembly is used so that the signal can be transmitted to the fixedly installed measuring device while the rotary kiln rotates;

[0022] When scale forms on the outer wall of the protective sleeve 8, the motor 1 drives the screw 9 to rotate, pushing the threaded block 11, so that the mounting ring 7 drives a pair of brushes to brush off the scale on the outer wall of the protective sleeve 8. When the cement kiln is in operation, the equipment can still operate, avoiding the inconvenience of stopping for cleaning and the danger of high temperature. The heat energy is effectively transferred, and the thermal parameters of the cement kiln are effectively and accurately monitored.

[0024] In this embodiment, when the mounting ring 7 moves, the sleeve ring 16 is driven to move synchronously, and the brush strip 17 on the inner wall of the sleeve ring 16 brushes away the scale on the outer wall of the screw 9, avoiding severe wear on the threads of the outer wall of the screw 9 and the inner wall of the threaded block 11, thereby playing an effective role in protecting the threads of the screw 9 and the threaded block 11 and reducing the loss of cleaning equipment.
