Description

Technical Field

[0001] This utility model relates to the field of all-hydrogen bell-type furnace technology, and in particular to an all-hydrogen bell-type furnace with a temperature acquisition device. Background Art

[0002] A bell-type annealing furnace is used for the heat treatment of coils. The heating quality of the furnace is a key issue in the production process. The uniformity and compliance of the mechanical properties of the coils depend primarily on the level of temperature control and temperature uniformity. Testing the temperature uniformity of coils in the bell-type annealing furnace is a primary means of understanding the coil temperature during actual production, providing a basis for the control and adjustment of heat treatment. Furthermore, the test results can be used to further optimize the airflow organization within the furnace. Therefore, it is necessary to monitor the temperature of the bell-type annealing furnace.

[0003] To obtain temperature field information of steel coils during annealing, existing technologies typically insert thermocouples at specific locations within the steel coil and then place the coil in an annealing furnace for annealing. This allows for direct measurement of temperature changes at different locations within the steel coil throughout the annealing process, thereby deriving the temperature field characteristics of other locations within the coil. However, the relatively fixed positions of the thermocouples result in limited measurement results that cannot accurately reflect the overall temperature situation inside the furnace, hindering subsequent temperature adjustments. Utility Model Content

[0004] The purpose of this invention is to provide a full-hydrogen bell-type furnace with a temperature acquisition device, which solves the technical problem that the temperature acquisition results of existing full-hydrogen bell-type furnaces are singular and cannot accurately reflect the conditions inside the furnace.

[0005] This application discloses a full-hydrogen bell-type furnace with a temperature acquisition device, comprising:

[0006] The furnace body is used for heat treatment of coiled wire.

[0007] A temperature measuring unit is installed at the drain port of the furnace body, and the temperature measuring unit includes:

[0008] Black box temperature measurement module;

[0009] The outer casing is fitted onto the temperature measurement module of the black box;

[0010] Water-cooled pipes are wound around the temperature measurement module of the black box, and the inlet and outlet of the water-cooled pipes extend out of the outer casing;

[0011] Multiple K-type thermocouples are connected at one end to the temperature measurement module of the black box, and at the other end extend into the furnace body.

[0012] This application enables multi-point temperature measurement using multiple K-type thermocouples, and also incorporates water-cooling pipes to reduce the temperature of the black box temperature measurement module, thus ensuring the lifespan of the device.

[0013] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0014] Furthermore, the K-type thermocouple includes seven furnace-in-the-box detection thermocouples and three coiled detection thermocouples; the ends of the coiled detection thermocouples are in contact with the inner side of the coil; one of the furnace-in-the-box detection thermocouples is in contact with the bottom of the furnace body, and the remaining furnace-in-the-box detection thermocouples are evenly distributed inside the furnace body. The beneficial effect of this step is to achieve multi-point detection by using multiple K-type thermocouples.

[0015] Further, the housing includes:

[0016] steel sleeve;

[0017] An insulation layer is installed inside the steel sleeve. The beneficial effect of this step is that the insulation layer can reduce the impact of external temperature on the black box temperature measurement module.

[0018] Furthermore, a flange plate is provided at the end of the steel sleeve. The beneficial effect of this step is that the flange plate facilitates the installation stability of the entire product.

[0019] Furthermore, the black box temperature measurement module is equipped with a wireless transmission unit. The advantage of this step is that wireless transmission is achieved through the wireless transmission unit, which facilitates subsequent data collection.

[0020] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0021] 1. This application incorporates a temperature measurement unit into the overall furnace design, using a K-type thermocouple in conjunction with a black box temperature measurement module to perform temperature measurement operations on the furnace body, thereby obtaining information about the overall condition inside the furnace body.

[0022] 2. This application also includes an insulation layer and cooling pipes, which can reduce the temperature of the black box temperature measurement module, thereby ensuring the service life of the black box temperature measurement module. Attached Figure Description

DETAILED DESCRIPTION

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0033] Example:

[0034] like Figure 1 , 2 As shown, this application discloses a full hydrogen bell-type furnace with a temperature acquisition device. Compared with the existing full hydrogen bell-type furnace, the temperature acquisition device can fully detect the temperature inside the furnace, thereby ensuring the uniformity of the temperature inside the furnace and thus ensuring the effect of heat treatment.

[0035] This application specifically includes:

[0036] Furnace body 1 is used to perform heat treatment of coils. This furnace body is a full hydrogen hood furnace, which is an existing furnace body. The specific structure will not be described in detail.

[0037] Temperature measuring unit 2 is installed at the drain port of the furnace body 1. This temperature measuring unit 2 is used to detect the temperature inside the furnace body 1, so as to know the temperature inside the furnace body and make subsequent adjustments according to the actual situation.

[0038] The temperature measuring unit 2 includes:

[0039] Black box temperature measurement module 201, which is an existing module used for temperature detection;

[0040] The outer casing 202 is fitted onto the black box temperature measurement module 201. The outer casing 202 is used to protect the black box temperature measurement module 201 and serves to keep it warm.

[0041] A water-cooled pipe 203 is wound around the black box temperature measurement module 201, and the inlet and outlet of the water-cooled pipe 203 extend out of the outer shell 202. In use, cooling water is added to the water-cooled pipe 203 to process the black box temperature measurement module 201, thereby achieving the function of heat preservation. Because the temperature inside the all-hydrogen bell furnace is high, the water-cooled pipe is used to achieve the function of cooling in order to ensure the stability of temperature measurement.

[0042] Multiple K-type thermocouples 204 are connected at one end to the black box temperature measurement module 201 and at the other end to the interior of the furnace body 1. Temperature detection can be achieved through the K-type thermocouples, i.e., multi-point temperature detection.

[0043] To ensure the accuracy of temperature measurement, such as Figure 2 As shown, there are 10 K-type thermocouples 204 in this application. One end of each K-type thermocouple 204 is electrically connected to the temperature measurement module of the black box, and the other end extends into the furnace body 1 for temperature measurement. Specifically, the K-type thermocouple 204 includes seven furnace-in-place detection thermocouples 205 and three coiled detection thermocouples 206. The ends of the coiled detection thermocouples 206 respectively contact the inner side of the coil, that is, three of them are used to detect the temperature of the coil. In addition, to ensure uniformity, they can also be set at the top and middle of the coil. The furnace body consists of three parts: one of the furnace-in-furnace detection thermocouples 205 is in contact with the bottom of the furnace body 1, and the remaining furnace-in-furnace detection thermocouples 205 are evenly distributed inside the furnace body 1. This allows for thorough detection of the internal temperature of the furnace body 1. Additionally, one furnace-in-furnace detection thermocouple 205 is in direct contact with the bottom of the furnace body 1. Since the bottom of the furnace body is equipped with a thermocouple for heating, this is closer to the thermocouple, allowing for more accurate determination of the heating temperature after detection, which facilitates subsequent temperature control.

[0044] To achieve thermal insulation and structural stability, the outer casing 202 described in this application includes:

[0045] Steel sleeve 207, which is a heat-resistant steel outer shell, is used for protection, as this application requires it to be installed inside the furnace body 1;

[0046] The insulation layer 208 is disposed inside the steel sleeve 207. The insulation layer 208 mainly plays a protective role, preventing the high temperature inside the furnace from affecting the black box temperature measurement module itself.

[0047] Specifically, the end of the steel sleeve 207 in this application is provided with a flange plate 209, which can cooperate with the flange end of the sewage outlet to achieve the stability of the structural installation.

[0048] When measuring and obtaining the corresponding data, this application provides a wireless transmission unit 210 on the black box temperature measurement module 201. The wireless transmission unit 210 is an existing unit, which can be an antenna or other existing module, to realize data transmission, and then the data is received through components such as a computer.

[0049] Further explanation is provided regarding this application:

[0050] This application relates to a full-hydrogen bell-type furnace for temperature acquisition. Specifically, it uses a K-type thermocouple for temperature acquisition and a water-cooling pipe to cool the black box temperature measurement module to prevent damage caused by excessively high temperatures inside the furnace. At the same time, insulation material is installed inside the outer shell to further protect the black box temperature measurement module from high temperatures and damage.
