Description

Technical Field

[0001] This utility model belongs to the field of tubular furnace technology, specifically relating to a multi-point temperature measurement tubular gradient furnace. Background Technology

[0002] Tube furnaces are commonly used equipment in laboratories for controlled temperature and atmosphere heating of samples, and can be divided into two main categories: vertical tube furnaces and horizontal tube furnaces. As a commonly used vertical pyrolysis, gasification, and combustion device in simulation engineering, vertical tube furnaces have gradually become a common piece of equipment for studying the pyrolysis and combustion of biomass and other samples.

[0003] Some tube furnaces on the market are divided into multiple zones, each with a different temperature, for facilitating material processing at different stages. During material feeding, the material needs to flow between these zones, and the openings between zones must remain open to allow material to enter and exit. However, keeping the openings open leads to heat exchange between zones, which is detrimental to temperature control within each zone. Therefore, this application proposes a multi-point temperature measurement tube gradient furnace. Utility Model Content

[0004] The purpose of this invention is to provide a multi-point temperature measuring tube gradient furnace to solve the problem mentioned in the background art that the material needs to flow between different areas. During the flow, it is necessary to keep the openings between the areas open so that the material can enter and exit. However, if the openings between the areas are kept open, heat will interact between the areas, which is not conducive to the control of the temperature inside the area.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-point temperature measuring tubular gradient furnace, including a tubular furnace body, a temperature control mechanism, and a temperature sensor. The tubular furnace body is provided with two furnace body dividing mechanisms, which divide the tubular furnace body into a lower furnace, a middle furnace, and an upper furnace. The tubular furnace body is equipped with three temperature control mechanisms and three temperature sensors. The furnace body dividing mechanism includes a cover plate, a tilting plate, a tilting shaft, a tilting motor, and a tilting adsorption mechanism. The cover plate is installed on the inner wall of the tubular furnace body and is movably connected to the tilting plate. The tilting shaft is inserted into the tilting plate and is drively connected to the tilting plate. The output end of the tilting motor is connected to the tilting shaft. A storage rack is provided at the body of the tubular furnace, and the flipping adsorption mechanism is installed on the flipping plate. The furnace is equipped with a lifting mechanism, a telescopic unit, and an L-plate. The lifting mechanism is connected to the telescopic unit, and the lifting mechanism can drive the telescopic unit to move up and down. The telescopic unit is connected to the L-plate.

[0006] Preferably, a furnace body support is provided on the outside of the tubular furnace body, and multiple furnace body supports are arranged in a circumferential array around the center line of the tubular furnace body.

[0007] Preferably, the three temperature control mechanisms are used to supply heat to the lower furnace, the middle furnace, and the upper furnace, respectively, and the three temperature sensors are used to measure the temperature inside the lower furnace, the middle furnace, and the upper furnace, respectively.

[0008] Preferably, the tubular furnace body is provided with two connecting sleeves, which are fixedly connected to the outer wall of the tubular furnace body, and the rotating shaft is inserted into the connecting sleeves.

[0009] Preferably, the storage rack includes a lower storage box, an upper cover, a first suction plate, and a second suction plate, with the lower storage box and the upper cover being detachably connected.

[0010] Preferably, the lower storage box has several through holes.

[0011] Preferably, a first adsorption plate is installed at the bottom of the lower storage box, and a second adsorption plate is provided on the upper side of the upper cover.

[0012] Preferably, a top cover is provided on the top of the tubular furnace body.

[0013] Preferably, a telescopic rod is provided at the top cover, and a loading and unloading adsorption mechanism is provided at the output end of the telescopic rod.

[0014] Preferably, there are two telescopic units and two lifting mechanisms, with the two telescopic units located on both sides of the storage rack.

[0015] Beneficial effects: This utility model provides a multi-point temperature measuring tubular gradient furnace. The flipping motor in the furnace body segmentation mechanism can drive the flipping shaft to rotate. When the flipping shaft rotates, it can drive the flipping plate to rotate. The flipping adsorption mechanism on the flipping plate can adsorb the storage rack and rotate the storage rack synchronously, thereby sending the storage rack from the upper furnace into the middle furnace. The lifting mechanism inside the middle furnace can drive the storage rack to move in the middle furnace, and then move the storage rack to the lower furnace body segmentation mechanism. The lower furnace body segmentation mechanism is activated, thereby sending the storage rack from the middle furnace into the lower furnace. The above operation is reversed to send the storage rack back into the upper furnace. In this way, the material can be transferred between the lower furnace, middle furnace and upper furnace. During the transfer, the heat exchange time between different areas in the tubular furnace body is reduced, which facilitates temperature control in different areas of the tubular furnace body.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1-5 As shown in the figure, the multi-point temperature measurement tubular gradient furnace provided by this utility model includes a tubular furnace body 1, a temperature control mechanism, and a temperature sensor. Two furnace body dividing mechanisms 3 are provided inside the tubular furnace body 1, which divide the tubular furnace body 1 into a lower furnace 101, a middle furnace 102, and an upper furnace 103. A furnace body support 2 is provided on the outside of the tubular furnace body 1, and multiple furnace body supports 2 are arranged in a circumferential array around the center line of the tubular furnace body 1.

[0020] In order to measure and control the temperature in the lower furnace 101, the middle furnace 102, and the upper furnace 103, three temperature control mechanisms and three temperature sensors are installed in the tubular furnace body 1. The three temperature control mechanisms are used to supply heat to the lower furnace 101, the middle furnace 102, and the upper furnace 103, respectively, and the three temperature sensors are used to measure the temperature in the lower furnace 101, the middle furnace 102, and the upper furnace 103, respectively. It should be noted that there are two furnace body dividing mechanisms 3. Two temperature sensors are located on the upper and lower sides of the second furnace body dividing mechanism 3, and the other temperature sensor is located on the upper side of the first furnace body dividing mechanism 3.

[0021] Specifically, the furnace body dividing mechanism 3 includes a cover plate 301, a tilting plate 302, a tilting shaft 303, a tilting motor 304, and a tilting adsorption mechanism 306. The cover plate 301 is installed on the inner wall of the tubular furnace body 1. The cover plate 301 is movably connected to the tilting plate 302. The tilting shaft 303 is inserted into the tilting plate 302 and is connected to the tilting plate 302 in a transmission manner. The tilting shaft 303 and the tilting plate 302 can be connected by a flat key or a keyway. When the tilting shaft 303 rotates, it can drive the tilting plate 302 to rotate. The material can rotate together with the tilting plate 302, thereby sending the material from the upper furnace 103 into the middle furnace 102, or sending the material from the middle furnace 102 into the lower furnace 101.

[0022] More specifically, the output end of the rotating motor 304 is connected to the rotating shaft 303. The output shaft of the rotating motor 304 and the rotating shaft 303 are connected by a coupling. In order to stabilize the rotating shaft 303, two connecting sleeves 305 are provided at the tubular furnace body 1. The connecting sleeves 305 are fixedly connected to the outer wall of the tubular furnace body 1. The rotating shaft 303 is inserted into the connecting sleeves 305. Specifically, the rotating shaft 303 and the connecting sleeves 305 are connected by bearings.

[0023] It should be noted that a storage rack 4 is provided at the tube furnace body 1. The storage rack 4 is for storing materials for processing. In order to adsorb and release the storage rack 4, a flip adsorption mechanism 306 is installed on the flip plate 302. The flip adsorption mechanism 306 can be a common electromagnet.

[0024] For reference Figure 3 The storage rack 4 includes a lower storage box 401, an upper cover 402, a first adsorption plate 403, and a second adsorption plate 404. The lower storage box 401 has several through holes, which allow the heat inside the tubular furnace body 1 to contact the material in the lower storage box 401. The lower storage box 401 and the upper cover 402 are detachably connected. Specifically, the lower storage box 401 and the upper cover 402 are connected by bolts. The first adsorption plate 403 is installed at the bottom of the lower storage box 401, and the second adsorption plate 404 is provided on the upper side of the upper cover 402.

[0025] Both the first adsorption plate 403 and the second adsorption plate 404 are made of magnetic materials and can be attracted and released by electromagnets.

[0026] In order to enable the storage rack 4 to move within the upper furnace 103, a top cover 7 is provided on the top of the tubular furnace body 1. A telescopic rod 5 is provided on the top cover 7. The telescopic rod 5 can be a common hydraulic cylinder. A loading and unloading adsorption mechanism 6 is provided at the output end of the telescopic rod 5. The loading and unloading adsorption mechanism 6 also uses an electromagnet.

[0027] In order to enable the storage rack 4 to move between the two furnace body dividing mechanisms 3, a lifting mechanism 8, a telescopic unit 9, and an L-plate 10 are provided in the middle furnace 102. The lifting mechanism 8 is connected to the telescopic unit 9, and the lifting mechanism 8 can drive the telescopic unit 9 to move up and down. The telescopic unit 9 is connected to the L-plate 10. The telescopic unit 9 can be a high-temperature resistant electric telescopic rod. There are two telescopic units 9 and two lifting mechanisms 8. The two telescopic units 9 are located on both sides of the storage rack 4. The telescopic unit 9 can drive the L-plate 10 to move, thereby realizing the clamping and releasing function of the storage rack 4.

[0028] In summary, this utility model embodiment provides a multi-point temperature measurement tubular gradient furnace. The tubular furnace body 1 is provided with two furnace body dividing mechanisms 3, which divide the tubular furnace body 1 into a lower furnace 101, a middle furnace 102, and an upper furnace 103. The tubular furnace body 1 is provided with three temperature control mechanisms and three temperature sensors. The three temperature control mechanisms are used to heat the lower furnace 101, the middle furnace 102, and the upper furnace 103, respectively, and the three temperature sensors are used to measure the temperature in the lower furnace 101, the middle furnace 102, and the upper furnace 103, respectively. In this way, the tubular furnace body 1 is divided into three areas with different temperatures for segmented processing of the materials to be processed.

[0029] The flipping motor 304 in the furnace body dividing mechanism 3 can drive the flipping shaft 303 to rotate. When the flipping shaft 303 rotates, it can drive the flipping plate 302 to rotate. The flipping adsorption mechanism 306 on the flipping plate 302 can adsorb the storage rack 4 and rotate it synchronously, thereby sending the storage rack 4 from the upper furnace 103 into the middle furnace 102. The lifting mechanism 8 inside the middle furnace 102 can drive the storage rack 4 to move within the middle furnace 102, thereby moving the storage rack 4 to the lower furnace body dividing mechanism 3. The lower furnace body dividing mechanism 3 is activated, thereby sending the storage rack 4 from the middle furnace 102 into the lower furnace 101. By reversing the above operation, the storage rack 4 can be sent back to the upper furnace 103. In this way, the material can be transferred between the lower furnace 101, the middle furnace 102, and the upper furnace 103. During the transfer process, the heat exchange time between different areas in the tubular furnace body 1 is less, which facilitates temperature control in different areas of the tubular furnace body 1.

[0030] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
