Description

Technical Field

[0001] This utility model relates to the field of high-temperature box-type resistance furnaces, specifically to a high-temperature box-type resistance furnace that is easy to clean. Background Technology

[0002] Box-type resistance furnaces are heat treatment equipment widely used in industrial production and laboratory research. Their core function is to heat materials inside the furnace by passing electricity through resistance wires. They employ a rectangular or square box structure, welded from steel plates, providing excellent sealing and mechanical strength. The internal furnace chamber is typically constructed of refractory materials to withstand high temperatures and minimize heat loss.

[0003] A search revealed a utility model patent with publication number CN219607695U, which discloses an improved box-type resistance furnace. The furnace includes a box-type resistance furnace and a base. Straight plates are fixedly attached to the lower left and right sides of the inner wall of the box-type resistance furnace. A placement plate is slidably engaged with the inner side of each straight plate. Gear plates are fixedly attached to the left and right sides of each placement plate. Control structures are connected to the left and right sides of the top of the box-type resistance furnace. A bracket is fixedly attached to the top front of the top straight plate. Through the control structure, a handle on one side drives a grooved wheel to rotate. The rotating grooved wheel, in conjunction with a belt, drives the other grooved wheel to rotate, causing both vertical rods to rotate simultaneously. The rotating vertical rods, in conjunction with gears, drive the gear plates forward, thereby moving the placement plate forward inside the straight plates and gradually removing it from the interior of the box-type resistance furnace. This simultaneous control from both sides avoids jamming, eliminates the limitations of using box-type resistance furnaces, and ensures their service life.

[0004] During the use of existing box-type resistance furnaces, some residue is easily left on the furnace wall after heat treatment. If it is not cleaned in time, it can easily lead to a decline in its working quality. However, due to the presence of heating rods and other components on its inner wall, cleaning the inside is quite difficult, thus affecting its normal use.

[0005] Therefore, it is necessary to invent a high-temperature box-type resistance furnace that is easy to clean in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a high-temperature box-type resistance furnace that is easy to clean. By quickly disassembling the placement box, residues can be avoided from remaining inside the resistance furnace. Furthermore, the disassembly process of the placement box also produces a cleaning effect, thus solving the problem of difficult internal cleaning of resistance furnaces in the prior art, which affects their normal use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature box-type resistance furnace that is easy to clean, including a resistance furnace body, a door panel installed on one side of the resistance furnace body, a controller installed on the top of the resistance furnace body, and multiple sets of resistance heating rods installed sequentially on the inner wall of the resistance furnace body;

[0008] The cleaning assembly installed inside the resistance furnace includes a placement box, which is installed inside the resistance furnace, and multiple sets of through slots are sequentially opened inside the placement box.

[0009] The fixing component located on the outside of the placement box includes a connecting groove, which is formed on the outer surface of the placement box, and a limiting groove is formed on the inner wall of the connecting groove.

[0010] Preferably, the cleaning assembly further includes guide plates, which are symmetrically distributed in a figure-eight pattern on the inner wall of each set of through slots, with the openings of the guide plates facing outwards from the placement box. Multiple placement racks are installed on one side of the lower inner wall of the placement box.

[0011] Preferably, the fixing component further includes a push frame, which is disposed in the connecting groove, and a limiting frame is sleeved and fixed on the push frame, and the limiting frame is slidably connected to the limiting groove.

[0012] Preferably, multiple sets of limiting cylinders are symmetrically installed in sequence below the inner wall of the connecting groove. A limiting rod is slidably connected inside the limiting cylinder. A spring is attached between the limiting rod and the inner wall of the limiting cylinder, and the limiting rod is fixedly connected to the inner wall of the push frame.

[0013] Preferably, multiple sets of arc-shaped frames are installed on one side above the push frame, and the arc-shaped frames are in contact with the corresponding resistance heating rods.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The detachable placement box allows the arc-shaped frame to contact the resistance heating rod, and during disassembly, it makes rigid contact with the heating rod, thus scraping and cleaning its surface. Simultaneously, the complete disassembly of the placement box facilitates cleaning and the placement and removal of internal heat-treated objects. This structure allows the placement box to be stably placed inside the resistance furnace while also enabling rapid disassembly. The surface of the resistance heating rod can be cleaned during disassembly, and the disassembled placement box is also easy to clean. Furthermore, the guide plate maximizes heat retention within the placement box, thereby improving the heat treatment effect and preventing residues from entering the resistance furnace through the through-slot, significantly enhancing the ease of equipment cleaning.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-7 The high-temperature box-type resistance furnace shown includes a resistance furnace body 001, a door panel 101 installed on one side of the resistance furnace body 001, a controller 102 installed on the top of the resistance furnace body 001, and multiple sets of resistance heating rods 103 installed sequentially on the inner wall of the resistance furnace body 001.

[0028] The door panel 101 allows the resistance furnace body 001 to be opened and closed, and the resistance heating rod 103 allows the resistance furnace body 001 to be heated.

[0029] The cleaning component 002 installed inside the resistance furnace body 001 includes a placement box 201. The placement box 201 is installed inside the resistance furnace body 001, and multiple sets of through slots 202 are sequentially opened inside the placement box 201.

[0030] The through-slot 202 allows heat to enter the placement box 201, thereby achieving the effect of heat treatment on the objects inside the placement box 201.

[0031] The fixing component 003 located on the outside of the placement box 201 includes a connecting groove 301, which is formed on the outer surface of the placement box 201, and a limiting groove 302 is formed on the inner wall of the connecting groove 301.

[0032] Furthermore, in the above structure, the cleaning component 002 also includes a guide plate 203. The guide plates 203 are symmetrically distributed in a figure-eight pattern and installed on the inner wall of each set of through slots 202. The openings of the guide plates 203 are facing outwards from the placement box 201. Multiple sets of placement racks 204 are installed on one side of the lower inner wall of the placement box 201.

[0033] The guide plate 203 allows heat to enter the placement box 201 more effectively, and the guide plate 203 can also effectively prevent heat from being lost from the placement box 201. The placement rack 204 can fix the object in place.

[0034] Furthermore, in the above structure, the fixing component 003 also includes a push frame 303, which is disposed in the connecting groove 301. A limiting frame 304 is sleeved and fixed on the push frame 303, and the limiting frame 304 is slidably connected to the limiting groove 302.

[0035] The limiting frame 304 and the limiting groove 302 work together to allow the push frame 303 to slide within the connecting groove 301.

[0036] Furthermore, in the above structure, multiple sets of limiting cylinders 305 are symmetrically installed in sequence below the inner wall of the connecting groove 301. A limiting rod 306 is slidably connected inside the limiting cylinder 305. A spring 307 is attached between the limiting rod 306 and the inner wall of the limiting cylinder 305, and the limiting rod 306 is fixedly connected to the inner wall of the push frame 303.

[0037] The spring 307 can keep the position of the limiting rod 306 in the limiting cylinder 305, so that the push frame 303 is always in an upward moving state in the connecting groove 301.

[0038] Furthermore, in the above structure, multiple sets of arc-shaped frames 308 are installed on one side above the push frame 303, and the arc-shaped frames 308 are in contact with the corresponding resistance heating rods 103.

[0039] The movement of the push frame 303 allows the arc frame 308 to fit against the resistance heating rod 103, thereby achieving stability and easy disassembly of the placement box 201 within the resistance furnace body 001. Furthermore, during the pulling process of the placement box 201, the arc frame 308 can move along the surface of the resistance heating rod 103, thus achieving the effect of cleaning the surface of the resistance heating rod 103. Moreover, the disassembly of the placement box 201 not only facilitates the placement and removal of objects but also facilitates the cleaning of the placement box 201, thereby reducing the amount of residual impurities on the inner wall of the resistance furnace body 001.

[0040] The working principle of this practical application is as follows:

[0041] Refer to the instruction manual appendix Figure 1-7 The object requiring heat treatment is placed on the rack 204 inside the placement box 201. The placement box 201 is then pushed into the resistance furnace body 001, causing the arc-shaped frame 308 to contact and be compressed against the resistance heating rod 103, thus pushing the placement box 201 into the resistance furnace body 001. The door panel 101 is then closed for heat treatment. The heat generated by the resistance heating rod 103 flows through the through groove 202 into the placement box 201. The guide plate 203 facilitates heat entry while preventing heat loss. After treatment, the guide plate 203 prevents a large amount of debris generated during heat treatment from remaining in the resistance furnace body 001. Within 1, the removal of the placement box 201 also causes the arc frame 308 to move along the resistance heating rod 103, thereby cleaning its surface. This structure allows the placement box 201 to be stably placed inside the resistance furnace body 001 while also being quickly disassembled. During disassembly, the surface of the resistance heating rod 103 can be cleaned, and the disassembled placement box 201 is also easy to clean. At the same time, the guide plate 203 can maximize the heat retention inside the placement box 201, thereby improving the heat treatment effect and preventing residues from entering the resistance furnace body 001 through the through groove 202, thus greatly improving the convenience of equipment cleaning.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
