Description

Technical Field

[0001] This utility model relates to the field of kiln temperature measurement technology, and in particular to a temperature measuring device for kilns. Background Technology

[0002] Kilns are essential heating equipment in industrial production, widely used in metallurgy, ore sintering, coking, ceramics, and other fields. Temperature control is crucial during the kiln heating process, as it directly impacts product quality and production efficiency. Therefore, accurate and real-time monitoring of the kiln's temperature is key to ensuring smooth production.

[0003] Currently, most temperature measuring devices in kilns are integrated with the kiln itself, making maintenance and replacement inconvenient and increasing kiln costs. Furthermore, because the outer wall temperature of the kiln is high during operation, the temperature measuring device, when in close contact with the outer wall, will cause its interior to be at a high temperature, thus reducing its lifespan. In addition, existing temperature measuring devices mostly consist of a thermocouple and a temperature measuring cone. The temperature measuring cone is installed inside the kiln for temperature measurement, and positioning the cone during installation is inconvenient, thus affecting the accuracy of temperature detection. Utility Model Content

[0004] The purpose of this invention is to solve the problem that most temperature measuring devices in kilns are integrated with the kiln, making maintenance and replacement inconvenient, and that it is difficult to position the temperature measuring cone during installation, thus affecting the accuracy of temperature detection. Therefore, this invention proposes a temperature measuring device for kilns.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature measuring device for a kiln, comprising a kiln body and a temperature measuring instrument, wherein a heat-conducting wire is provided on the top of the temperature measuring instrument, a positioning block is fixedly installed at one end of the surface of the heat-conducting wire, mounting blocks are fixedly connected to both sides of the outer wall of the temperature measuring instrument, a fixing seat is fixedly installed on one side of the outer wall of the kiln body, a positioning groove is provided on the side of the fixing seat, an opening is provided on the top of the fixing seat, an mounting rod is fixedly connected to one side of the outer wall of the kiln body, the mounting block is slidably installed on the surface of the mounting rod, a limit block is fixedly connected to the surface of the mounting rod, a drive motor is fixedly installed inside the fixing seat, and a push rod is movably installed inside the mounting rod.

[0006] Preferably, a locking block is movably installed inside the mounting rod, the side of the locking block is disposed outside the mounting rod, and a connecting rod is movably installed on the other side of the locking block.

[0007] Preferably, a spring is fixedly connected to one side of the push rod, the spring is fixedly installed inside the mounting rod, and one end of the surface of the push rod is movably connected to the other side of the connecting rod.

[0008] Preferably, the shape of the positioning block matches the shape of the positioning groove, a push plate is movably installed inside the opening, and a connecting shaft is fixedly connected to the side of the push plate.

[0009] Preferably, the connecting shaft is movably mounted inside the fixed base, and a driven gear is fixedly mounted on one side of the connecting shaft.

[0010] Preferably, the output end of the drive motor is fixedly connected to a transmission gear, and the top of the transmission gear meshes with the bottom of the driven gear.

[0011] Preferably, a through hole is provided on the side of the kiln body, and the through hole is connected to the positioning groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the mounting block on the side of the thermometer is sleeved on the surface of the mounting rod. The locking block limits the mounting block, and pressing the push rod can cause the locking block to retract into the mounting rod, releasing the limitation on the mounting block, thereby facilitating the installation and disassembly of the thermometer.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1 like Figures 1-5 As shown, this utility model provides a technical solution: a temperature measuring device for a kiln, including a kiln body 1 and a thermometer 2. The top of the thermometer 2 is provided with a heat-conducting wire 21, and a positioning block 22 is fixedly installed at one end of the surface of the heat-conducting wire 21. Mounting blocks 23 are fixedly connected to both sides of the outer wall of the thermometer 2. A fixing seat 3 is fixedly installed on one side of the outer wall of the kiln body 1. A positioning groove 301 is opened on the side of the fixing seat 3, and an opening 302 is opened on the top of the fixing seat 3. An mounting rod 4 is fixedly connected to one side of the outer wall of the kiln body 1. The mounting blocks 23... A sliding mount is installed on the surface of the mounting rod 4. A limit block 41 is fixedly connected to the surface of the mounting rod 4. A drive motor 5 is fixedly installed inside the fixing seat 3. A push rod 6 is movably installed inside the mounting rod 4. A locking block 42 is movably installed inside the mounting rod 4. The side of the locking block 42 is located outside the mounting rod 4. A connecting rod 43 is movably installed on the other side of the locking block 42. A spring 61 is fixedly connected to one side of the push rod 6. The spring 61 is fixedly installed inside the mounting rod 4. One end of the surface of the push rod 6 is movably connected to the other side of the connecting rod 43.

[0019] In this embodiment, the mounting block 23 on the side of the thermometer 2 is slidably sleeved onto the surface of the mounting rod 4. It is blocked by the limiting block 41 on the surface of the mounting rod 4, causing it to stop moving. As the mounting block 23 moves on the surface of the mounting rod 4, it gradually presses against the locking block 42, causing the locking block 42 to retract inwards into the mounting rod 4. The movement of the locking block 42 adjusts the position and angle of the connecting rod 43, causing it to drive the push rod 6 inwards. Simultaneously, the push rod 6 compresses the spring 61 as it moves. When the mounting block 23 moves to the locking block... When the pressure on the locking block 42 is released, the spring 61 rebounds, causing the push rod 6 and the locking block 42 to return to their original positions. The shape of the locking block 42 can limit the installation block 23 on one side, making it convenient to install and fix the thermometer 2. Conversely, pushing the push rod 6 inward causes the locking block 42 to retract into the installation rod 4, releasing the limitation on the installation block 23, and the thermometer 2 can be disassembled. Since the installation position of the thermometer 2 is not close to the kiln body 1, it can prevent the outer wall temperature of the kiln body 1 from being too high and affecting the use of the thermometer 2.

[0020] Example 2 like Figures 1-5 As shown, the shape of the positioning block 22 matches the shape of the positioning groove 301. A push plate 31 is movably installed inside the opening 302. A connecting shaft 32 is fixedly connected to the side of the push plate 31. The connecting shaft 32 is movably installed inside the fixed seat 3. A driven gear 33 is fixedly installed on one side of the connecting shaft 32. A transmission gear 51 is fixedly connected to the output end of the drive motor 5. The top of the transmission gear 51 meshes with the bottom of the driven gear 33. A through hole 101 is opened on the side of the kiln body 1. The through hole 101 communicates with the positioning groove 301.

[0021] In this embodiment, after the thermometer 2 is installed, the heat-conducting wire 21 on its top is inserted into the positioning groove 301 and the through hole 101, so that one end of the heat-conducting wire 21 is installed inside the kiln body 1 to measure its temperature. When the positioning block 22 on the surface of the heat-conducting wire 21 is inserted into the positioning groove 301, the drive motor 5 is started to drive the transmission gear 51 to rotate. The transmission gear 51 meshes with the driven gear 33, causing it to drive the connecting shaft 32 to rotate together. At this time, the push plate 31 rotates downward around the connecting shaft 32 as the center. The push plate 31 gradually pushes the positioning groove 301 inside the positioning block 22, thereby installing and fixing the heat-conducting wire 21. At the same time, the positioning block 22 facilitates the positioning of the heat-conducting wire 21, thereby ensuring the accuracy of temperature measurement.

[0022] The working principle of this embodiment is as follows: The mounting block 23 is slidably sleeved on the surface of the mounting rod 4, so that it gradually presses against the locking block 42. The locking block 42 retracts into the mounting rod 4 and drives the push rod 6 to move inward together. At the same time, the push rod 6 will compress the spring 61 when it moves. When the mounting block 23 moves to one side of the locking block 42, the locking block 42 limits the mounting block, which facilitates the installation and fixation of the thermometer 2. Since the installation position of the thermometer 2 is not close to the kiln body 1, it can prevent the outer wall temperature of the kiln body 1 from being too high and affecting the use of the thermometer 2. Then, the heat conduction wire 21 on the top of the thermometer 2 is inserted into the positioning groove 301 and the through hole 101. The drive motor 5 is started to drive the transmission gear 51 and the driven gear 33 to rotate together. At this time, the push plate 31 rotates downward around the connecting shaft 32 as the center and pushes the positioning block 22 inward to install and fix the heat conduction wire 21.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
