DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figure 1-Figure 5 The present invention provides a technical solution: a combined connected box-type resistance furnace, comprising a furnace body 1, a furnace door 2 is hingedly connected to the outer wall of the furnace body 1, a rectangular groove 5 is opened on the outer wall of the furnace body 1, and a docking block 6 is fixedly connected to the inner wall of the furnace body 1, and also includes:

[0031] The heat conducting component 4 is arranged on the inner wall of the furnace body 1, and the heat conducting component 4 includes a heat insulating block 401, the outer wall of the heat insulating block 401 is fixedly connected to the inner wall of the furnace body 1, the outer wall of the heat insulating block 401 is provided with a constant temperature component 41, and the attached constant temperature component 41 is provided with a connecting component 3 outside, the inner wall of the heat insulating block 401 is fixedly connected with a reflecting block 402, the inner wall of the heat insulating block 401 is provided with a heat conducting hole 403, and the heat insulating block 401 is provided with a connecting hole 1 404 and a connecting hole 2 405 inside. 05, the inner wall of the heat insulation block 401 is fixedly connected with a guide sleeve 406, the outer wall of the guide sleeve 406 is provided with a guide hole 407, the inner wall of the guide sleeve 406 is fixedly connected with the outer wall of the heating block 408, the heating block 408 is a resistance heating block 408, which is used to heat the furnace, the guide hole 407 is used to guide the heat generated by the heating block 408, and the reflective block 402 is used to scatter the heat. When the combined connected box-type resistance furnace is put into use, The connecting assembly 3 assembles the furnace body 1 and insulates the inside of the furnace body 1 to prevent the temperature loss in the furnace body 1. The heating block 408 sends the heating heat to the furnace body 1 through the guide hole 1 407 opened on the outer wall of the guide sleeve 406 to heat the inside of the furnace body 1. The heat insulation block 401 protects the heat in the furnace to prevent the heat loss. The reflection block 402 on the inner wall of the heat insulation block 401 reflects the heat and disperses the heat to all parts of the furnace body 1. At the same time, the heat conduction hole 403 opened on the inner wall of the heat insulation block 401 guides the heat inside the furnace body 1 to prevent the heat from being concentrated on the top of the furnace body 1. After the hot air enters the heat conduction hole 403, it passes through the connecting hole 2 405 and conducts the heat to the lower temperature at the bottom of the inner wall of the heat insulation block 401, so that the heat in the furnace body 1 is kept balanced. The connecting hole 1 404 guides the heat introduced into the heat conduction hole 403 to the connection of the furnace body 1 and enters the constant temperature assembly 41 to dissipate the heat to prevent the heat at the connection of the furnace body 1 from being too low.

[0032] There are two groups of heat-conducting components 4, which are symmetrically arranged inside the two groups of furnace bodies 1 with the center line of the connecting sleeve 301 as the symmetry axis. There are four groups of guide sleeves 406 and heating blocks 408, which are equidistantly arrayed inside the insulation block 401 with the center line of the insulation block 401 as the rotation axis. The four groups of heating blocks 408 are used to heat the furnace. The heating blocks 408 arranged around the inner wall of the insulation block 401 guide the heat through the guide hole 407 opened on the outer wall of the guide sleeve 406, and release the heat in the furnace body 1 to heat the furnace rapidly. While the two groups of heat-conducting components 4 are respectively arranged inside the furnace body 1 for heat preservation, the heat inside the two groups of furnace bodies 1 is guided to keep the temperature at the connection between the two furnace bodies 1 stable.

[0033] The bottom of the heat conducting hole 403 is fixedly connected with the inside of the connection hole 1 404 and the connection hole 2 405. The heat conducting hole 403 is used to introduce heat into the connection hole 1 404 and the connection hole 2 405. The connection hole 1 404 and the connection hole 2 405 are used to circulate and guide the heat in the furnace. The heat inside the furnace body 1 is usually concentrated on the top of the furnace body 1, so that a certain temperature difference is generated in the furnace body 1. The heat from the top of the furnace body 1 is introduced into the connection hole 2 405 through the heat conducting hole 403. The temperature difference between the connection hole 2 405 and different parts of the inner wall of the insulation block 401 is different, so that air circulation is generated inside the connection hole 2 405, thereby reducing the temperature difference inside the furnace body 1.

[0035] The groove wall of the rectangular groove 5 is crimped with the outer wall of the top block 302. There are two groups of furnace bodies 1. The two groups of furnace bodies 1 are symmetrically arranged on the inner wall of the connecting sleeve 301 with the center line of the connecting sleeve 301 as the symmetry axis. The docking blocks 6 of the outer walls of the two groups of furnace bodies 1 match each other. The outer walls of the two groups of furnace bodies 1 are docked with each other through bolts passing through the through holes 304. The top block 302 is used to press the thermal insulation pad 303 when the furnace bodies 1 are connected. The top block 302 is placed in the rectangular groove 5, and the bolts are tightened during the assembly of the two furnace bodies 1, so that the rectangular groove 5 squeezes the top block 302 to slide in the assembly groove 305 opened on the inner wall of the connecting sleeve 301, so that the top block 302 squeezes the thermal insulation pad 303, and the thermal insulation pad 303 is deformed under the support of the docking block 6, so that the deformed thermal insulation pad 303 fills the gap generated when the two furnace bodies 1 are docked.

[0036] Example 3, based on Example 1, please refer to Figure 8The present invention provides a technical solution: the constant temperature component 41 includes a constant temperature block 411, the outer wall of the constant temperature block 411 is fixedly connected to the outer wall of the insulation block 401, the inner wall of the constant temperature block 411 is provided with a heat conduction groove 412, the bottom of the groove wall of the heat conduction groove 412 is fixedly connected with a heat dissipation block 413, the outer wall of the constant temperature block 411 is provided with a second guide hole 414, the second guide hole 414 is connected with the inside of the heat conduction groove 412, the second guide hole 414 is used to guide the internal heat of the guide hole 1 407 to the heat conduction groove 412, and guide the heat in the furnace body 1 to the constant temperature block 411 at the connection hole 1 404, the second guide hole 414 is connected with the connection hole 1 404, and the heat in the connection hole 1 404 is introduced into the heat conduction groove 412, and the heat inside the two furnace bodies 1 is conducted to the connection through the heat dissipation block 413, so as to supplement the temperature of the connection;

[0037] There are two groups of thermostatic blocks 411, which are symmetrically arranged inside the furnace body 1 with the center line of the connecting sleeve 301 as the symmetry axis. The outer wall of one group of thermostatic blocks 411 located inside the left furnace body 1 is fixedly connected with a docking block 415, and the outer wall of one group of thermostatic blocks 411 located inside the right furnace body 1 is provided with a positioning hole 416. The outer wall of the docking block 415 is slidably connected with the hole wall of the positioning hole 416. The docking block 415 and the positioning hole 416 are used to compensate for the displacement caused by the temperature difference expansion at the connection of the furnace body 1. After the two furnace bodies 1 are heated, the low temperature at the connection will cause bending deformation. The two groups of thermostatic blocks 411 cooperate with the docking block 415 and the docking hole to compensate for the displacement, so as to prevent the high-temperature heating from causing deformation at the connection of the furnace body 1, and the displacement is guided to squeeze the thermostatic block 411, causing the thermostatic block 411 to break.

[0038] The second guide hole 414 passes through the constant temperature block 411 and is fixedly connected with the first connection hole 404. The second guide hole 414 passes through the heat sink 413 so that the gap of the heat sink 413 is connected with the inside of the second guide hole 414. The outer wall of the constant temperature block 411 is fixedly connected with the inner wall of the furnace body 1. The heat sink 413 is used to release the heat guided to the connection of the furnace body 1. The heat sink 413 transfers the heat inside the connection hole 404 to the heat sink 413 through the second guide hole 414, and evenly flows out from the gap of the heat sink 413, so that the heat sink 413 quickly conducts the heat, so that the temperature inside the connection of the furnace body 1 is quickly replenished and kept consistent with the heat in the furnace body 1.
