Description

Technical Field

[0001] This utility model relates to the field of rotary kiln temperature measurement technology, specifically, to a rotary kiln temperature measurement device. Background Technology

[0002] Rotary kilns generally refer to rotary bed kilns, which are rotary calcining kilns that resemble a rotary bed in shape. They belong to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns, and lime kilns according to the materials they process. In order to ensure production safety and equipment safety, rotary kilns need to be temperature-controlled when operating in high-temperature environments. If the temperature is not properly controlled, it may lead to equipment damage or even safety accidents. By monitoring the temperature of the rotary kiln in real time, abnormal high temperatures or abnormal temperature change trends can be detected in time, so as to take measures to avoid serious accidents such as red-hot kilns or collapses.

[0003] A search revealed an existing technology (publication number: CN212512413U) for a real-time temperature measurement system for a rotary kiln using thermal imaging. The document states that the system includes a host computer and a temperature measuring device, which comprises a support frame and several temperature sensor groups. Each temperature sensor group includes several individual temperature sensors. The temperature sensors are communicatively connected to the host computer. The support frame covers the rotary kiln and is fixedly connected to the ground. The temperature sensor groups are arranged along the axial direction of the rotary kiln and mounted on the support frame, and are fixedly connected to the support frame. However, this existing technology measures the temperature of the rotary kiln from the outside. This method cannot directly measure the temperature from the inside of the kiln, and the exterior of the rotary kiln is usually covered with an insulation layer, which prevents heat dissipation. This results in a large temperature measurement error, affecting the accuracy of the final temperature reading. Therefore, designing a rotary kiln temperature measuring device is essential. Utility Model Content

[0004] The purpose of this invention is to provide a rotary kiln temperature measuring device that solves the problem that in the relevant technology, the temperature cannot be directly measured from inside the rotary kiln during use, and the temperature measurement error is large due to the influence of the insulation layer, which affects the accuracy of the final temperature measurement value.

[0005] The technical solution of this utility model is as follows:

[0006] A rotary kiln temperature measuring device includes a rotary kiln body. A movable tube is welded to one side of the outer wall of the rotary kiln body, and a heat-conducting block is inserted into one end of the movable tube. A thermocouple is inserted into the other end of the movable tube, and the hot end of the thermocouple is welded and fixed to one end of the heat-conducting block. A temperature display is screwed to the cold end of the thermocouple, and a sealing gasket is glued to the cold end of the thermocouple, and the sealing gasket is attached to the other end of the movable tube. Side plates are screwed to both sides of the outer wall of the sealing gasket. A heat insulation cover is screwed to one side of the outer wall of the rotary kiln body, and the heat insulation cover is located outside the movable tube. A handwheel is provided on one side of the heat insulation cover, and a winding roller is welded to one end of the handwheel. A connecting rope is wound on the winding roller, and the other end of the connecting rope is fixed to a side plate by screwing. A cover plate is installed on the top of the heat insulation cover by a torque hinge.

[0007] Preferably, the heat-conducting block is made of cobalt-chromium-tungsten alloy material, and the outer contour of the heat-conducting block fits the inner contour of the movable tube, and the diameter of the sealing gasket is larger than the diameter of the movable tube.

[0008] Preferably, the cover plate is welded with an internally threaded tube, and a hand-tightening screw is installed inside the internally threaded tube via threads.

[0009] Preferably, a scraper ring is welded to the outer wall of one end of the movable tube, and the scraper ring is inclined. The scraper ring is screwed and fixed to the inner wall of the rotary kiln body.

[0010] Preferably, a limiting ring is welded to the inner wall of the other end of the movable tube, and the thermocouple passes through the limiting ring. The inner diameter of the limiting ring is smaller than that of the heat-conducting block.

[0011] Preferably, the rotary kiln body includes a kiln lining, a kiln shell, and an insulation layer. The kiln lining is located inside the rotary kiln body, and the kiln shell is located outside the kiln lining. The kiln shell is covered with an insulation layer, which is made of ceramic fiber.

[0012] Preferably, the connecting rope is made of nylon material and the sealing gasket is made of nitrile rubber.

[0013] Preferably, the temperature display is an LCD temperature display.

[0014] The beneficial effects of this utility model are:

[0015] The thermocouple is fully heated inside the rotary kiln by the heat-conducting block. When the temperature needs to be checked, the cover plate is lifted and the handwheel is turned to rewind the connecting rope by the winding roller. The traction force of the connecting rope can be used to pull the thermocouple outward, making it convenient for the temperature measurement personnel to check the measured temperature. The heat is transferred to the hot end of the thermocouple through the heat-conducting block, and then the cold end of the thermocouple transmits the converted temperature value to the temperature display for display. This method can directly measure the temperature inside the rotary kiln, with high temperature measurement accuracy, small error, and more accurate and reliable measured values. In addition, the heat insulation cover can protect the thermocouple and other components to prevent collision damage and affect the accuracy of temperature measurement. Attached Figure Description

[0024] like Figure 1-5As shown, this embodiment proposes a rotary kiln temperature measuring device, including a rotary kiln body 1. A movable tube 2 is welded to one side of the outer wall of the rotary kiln body 1, and a heat-conducting block 3 is inserted into one end of the movable tube 2. A thermocouple 4 is inserted into the other end of the movable tube 2, and the hot end of the thermocouple 4 is welded and fixed to one end of the heat-conducting block 3. A temperature display 5 is screwed to the cold end of the thermocouple 4, and a sealing gasket 6 is glued to the cold end of the thermocouple 4. The sealing gasket 6 is attached to the other end of the movable tube 2. Side plates 7 are screwed to both sides of the outer wall of the sealing gasket 6. A heat insulation cover 8 is screwed to one side of the outer wall of the rotary kiln body 1, and the heat insulation cover 8 is located on the movable tube 2. Outside the moving tube 2, a handwheel 9 is provided on one side of the heat insulation cover 8, and a winding roller 10 is welded to one end of the handwheel 9. A connecting rope 11 is wound on the winding roller 10, and the other end of the connecting rope 11 is fixed to a side plate 7 by screws. A cover plate 12 is installed on the top of the heat insulation cover 8 by a torque hinge. The heat conducting block 3 is made of cobalt-chromium-tungsten alloy material, and the outer contour of the heat conducting block 3 fits the inner contour of the moving tube 2. The diameter of the sealing gasket 6 is larger than the diameter of the moving tube 2. An internally threaded tube 13 is welded to the cover plate 12, and a hand-tightening screw 14 is installed inside the internally threaded tube 13 by threads. The cover plate 12 is in contact with the heat insulation cover 8. When the valve is closed, turning the hand screw 14 will press it against the side plate 7 and push the thermocouple 4 into the movable tube 2 until the heat-conducting block 3 is pushed into the rotary kiln body 1, so that the heat-conducting block 3 can be fully heated. A scraper ring 15 is welded to the outer wall of one end of the movable tube 2. The scraper ring 15 is inclined and is screwed to the inner wall of the rotary kiln body 1. The scraper ring 15 can scrape off the material attached to the heat-conducting block 3 when the heat-conducting block 3 retracts into the movable tube 2. A limit ring 16 is welded to the inner wall of the other end of the movable tube 2, and the thermocouple 4 passes through the limit ring 16.
