Description

Technical Field

[0001] The utility model shows a Joule heat heating device, belonging to the technical field of nano material heating devices. Background Art

[0002] The rapid and efficient high-temperature thermal shock technology is a unique and novel method for preparing various nanomaterials for energy storage and conversion. The entire preparation process lasts only a few seconds or milliseconds, and the heating / cooling rate can be as high as 10 5 K / s, the reaction temperature can reach above 3000K. The high-temperature thermal shock device mainly consists of four parts, namely DC power supply, heating reaction chamber, spectrometer and vacuum pump. Specifically, the sample material is connected to the copper sheet through conductive silver glue and fixed on the glass bracket, and the copper sheets at both ends of the sample are connected to the DC power supply. When the power is turned on, a high-temperature thermal shock will be triggered; the spectrometer is used to record the emission spectrum and estimate the sample temperature; the blackbody radiation equation is used to fit the emission spectrum of the sample, and the instantaneous temperature of the conductive sample during the high-temperature thermal shock process can be analyzed.

[0003] However, current heating equipment, when in use, usually uses methods such as fuel combustion or medium heat exchange to heat the reaction tube. The heat is then transferred to the inner wall of the reaction tube, and then further transferred to the catalyst and active center through heat convection, heat conduction, etc. In this process, the heat needs to undergo multiple transfers, which will cause a series of problems, such as increased thermal resistance and reduced heat transfer rate. These problems further lead to adverse consequences such as difficulty in matching heat transfer and reaction heat, increased temperature gradients, and decreased catalytic reaction performance. In addition, the above process is also prone to produce a large temperature difference between the inner and outer walls of the reaction tube, and this temperature difference will affect the structure of the tube and related performance such as service life. In addition, the time required for a single heating in the traditional heating method is long, and the cooling rate is slow, which is easy to affect the production efficiency of the sample.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] As shown in Figures 1 to 4 The utility model discloses a joule heating equipment, including the box 1 and the power supply component for the box 1 power supply, the front side of the box 1 is rotatably connected with the box door 11 sealed with the box 1, the opposite two inner side walls of the box 1 are equipped with multiple slide rails 12, and the same layer two slide rails 12 are respectively connected with the positive and negative poles of the power supply component, the drawer 2 is slidably installed on each slide rail 12, and the drawer 2 includes the side plate 22 slidably connected with the slide rail 12 and the conductive bottom plate 21 for placing the sample, the side plate 22 is equipped with the first conductive block 221 electrically connected with the conductive bottom plate 21, and when the drawer 2 is slid into the box 1, the first conductive block 221 is electrically connected with the power supply component through the slide rail 12.

[0030] The utility model discloses the box 1 is equipped with multiple drawers 2, and the sample is placed on the conductive bottom plate 21 of the drawer 2, when the drawer 2 is slid into the box 1, the power supply component is communicated with the conductive bottom plate 21 through the slide rail 12 and the first conductive block 221, and the current can directly heat the conductive bottom plate 21, so that the production efficiency of the sample can be effectively improved.

[0031] The drawer 2 described in this embodiment includes a conductive bottom plate 21, and the four sides of the conductive bottom plate 21 are respectively connected to a front plate, a rear plate and two side plates 22, wherein the two side plates 22 are slidably matched with the slide rail 12, and a grip portion is provided on the outer side surface of the front plate, and the user can put his hand into the grip portion to facilitate pushing the drawer 2 and making the drawer 2 slide along the slide rail 12; in addition, the conductive bottom plate 21 is mesh-shaped, and the conductive bottom plate 21 is made of stainless steel wire or aluminum wire or tungsten wire or copper wire or titanium wire or alloy wire, and a catalyst is coated on the conductive bottom plate 21. After the conductive bottom plate 21 is energized, the current can directly heat the catalyst, which can reduce the heat transfer resistance and increase the heat transfer rate on the one hand, and can also achieve simple and flexible regulation of the heating rate by adjusting the physical properties of the heating element material such as the heat capacity, showing the advantages of fast thermal response speed, high heating rate, and fast start and stop reaction.

[0032] Of course, it is understandable that in other embodiments, the catalyst may also be placed directly on the conductive bottom plate 21, making the placement of the catalyst simpler and more convenient.

[0033] The drawer 2 is fixed to the inner wall of the box body 1, and the bottom end of the fixing plate is provided with a support plate 121 extending back to the inner wall of the box body 1, and the top end of the fixing plate is provided with a top plate 122 extending back to the inner wall of the box body 1, and a slide groove 123 for the side plate 22 to be embedded is formed between the top plate 122 and the support plate 121. The support plate 121 provides a stable support for the drawer 2, ensuring that the sliding of the drawer 2 in the box body 1 is more stable and reliable, ensuring the stability and safety of the drawer 2 during the sliding process; in addition, the slide groove 123 structure formed between the top plate 122 and the support plate 121 can enhance the rigidity of the slide rail 12 and reduce the possibility of deformation or damage caused by external force. Secondly, the top plate 122 and the support plate 121 can also form a limit in the vertical direction for the drawer 2, making the assembly of the drawer 2 and the slide rail 12 more accurate and reliable, reducing the possibility of position deviation of the drawer 2, and ensuring that the drawer 2 can be stably installed in the slide rail 12.

[0034] like Figure 3 and Figure 4As shown, the fixed plate in the embodiment is provided with a second conductive block 124, which is electrically connected with the power supply assembly. When the drawer 2 is entirely slid into the cabinet 1, the first conductive block 221 keeps in contact with the second conductive block 124. In addition, the second conductive block 124 is installed at one end of the fixed plate close to the cabinet door 11, and the first conductive block 221 is installed at one end of the side plate 22 close to the cabinet door 11. When the drawer 2 is partially separated from the slide rail 12, the first conductive block 221 and the second conductive block 124 can be separated from each other, so that the conductive bottom plate 21 is disconnected with the power supply assembly, thereby avoiding the conductive bottom plate 21 still in the power-on state when the drawer 2 is pulled out, and effectively improving the application safety of the heating equipment and reducing the possibility of electric shock of the user.

[0035] Of course, it can be understood that in other embodiments, the second conductive block 124 can also be installed at one end of the slide rail 12 away from the cabinet door 11, and the first conductive block 221 is installed at one end of the side plate 22 away from the cabinet door 11.

[0036] In addition, the support plate 121 in the embodiment is also electrically connected with the power supply assembly, and the first conductive block 221 is at least partially on the bottom surface of the side plate 22. When the drawer 2 is entirely slid into the cabinet 1, the first conductive block 221 is in contact with the support plate 121, and the support plate 121 is on the lower side of the side plate 22, thereby keeping the support plate 121 in stable contact with the side plate 22. That is, when the drawer is entirely slid into the cabinet 1, the first conductive block 221 can be ensured to form stable contact with the support plate 121, so that the first conductive block 221 and the support plate 121 form reliable electrical connection, avoiding the short circuit problem caused by poor contact, and making the operation of the heating equipment more safe and reliable. In addition, the contact between the first conductive block 221 and the support plate 121 is relative to the traditional wiring mode, without the need for additional wiring posts, connectors or welding processes, thereby simplifying the electrical connection process, reducing the manufacturing cost and maintenance difficulty, and avoiding electrical failure caused by poor wiring or loose connector.

[0037] Of course, it can be understood that in other embodiments, the support plate 121 can also be the second conductive block 124.

[0038] As Figure 1 and Figure 2The box 1 is provided with an air outlet 16 and an air inlet 17 in the embodiment, the air outlet 16 is connected with a true gas generator, the air inlet 17 is connected with an air inlet device for conveying inert gas into the box 1, the true gas generator evacuates the air in the box 1 through the air outlet 16 before use, so that the box 1 is kept in vacuum, then the air inlet device fills the inert gas into the box 1 through the air inlet 17, so that the sample can be heated in the environment filled with inert gas; in addition, the outer side wall of the box 1 is provided with an air switch 13 and a plurality of wiring strips 15, a power supply assembly is electrically connected with the air switch 13, the air switch 13 is electrically connected with the wiring strips 15 through wires 14, and each wiring strip 15 is electrically connected with the second conductive block 124 of a layer of slide rails 12.
