[0001] The utility model relates to the technical field of industrial furnaces, in particular to industrial heat treatment equipment. Background Art
[0002] Industrial furnaces are equipment used in industrial manufacturing. Their structure, heating process, temperature control, and furnace atmosphere all directly affect product quality. Currently, the inner walls of industrial furnaces are filled with insulation foam to reduce and prevent heat loss and maintain a stable temperature field. However, the fastening nails currently used to secure the insulation foam are mostly heat-resistant metal nails. Heat within the furnace is easily conducted and dissipated through the metal nails, resulting in the insulation effect of some industrial furnaces with special requirements not meeting the requirements.
[0003] In addition, the existing heat treatment furnace also has insufficient insulation material filling inside the furnace body, which makes it easy for the heat in the furnace body to be conducted outward through the stainless shell of the furnace body wall through the gaps, making the temperature inside the furnace unstable and resulting in uncontrollable product quality. Utility Model Content

[0008] Preferably, the transverse cross-section of the heat-resistant support is U-shaped, and its size is adapted to the top of the furnace body.
[0009] Preferably, the heat-resistant support member is made of heat-resistant stainless steel.
[0010] Preferably, the inner wall of the furnace top is further covered with a partition piece, the partition piece is made of ceramic material, and the ceramic fasteners sequentially penetrate the partition piece and the thermal insulation material and fix them to the inner wall of the furnace top.
[0011] Preferably, a slag discharge port is provided on one side of the furnace body, and a protective net is provided on the outside of the slag discharge port.
[0012] Preferably, the induced draft system includes an induced draft fan and a plurality of induced draft ducts evenly distributed on the top of the furnace body and connected to the air inlet of the induced draft fan.
[0013] Preferably, the air inlet of the induced draft fan is connected to a main duct, one end of the induced draft duct is connected to the interior of the furnace body, and the other end is connected to the main duct.
[0014] The beneficial effects of the present invention are:

[0028] Example 1
[0029] like Figure 1-5 As shown, this embodiment provides an industrial heat treatment equipment, including: a furnace body 1 and an air induced draft system 2 arranged on the top of the furnace body 1, the inner wall of the furnace body 1 is covered with a thermal insulation material 13, and the thermal insulation material 13 is installed on the furnace body 1 through a plurality of ceramic fasteners 16. On the one hand, the compactness of the thermal insulation material 13 is increased to avoid the existence of gaps that cause heat loss to the outside; on the other hand, the heat loss caused by heat conduction of the ceramic fasteners 16 is further reduced, thereby improving the temperature stability in the furnace body 1 and ensuring reliable product quality.
[0030] A heat-resistant support 12 for positioning and pressing the heat-insulating material 13 is further provided on the inner side of the top of the furnace body 1 , and the ceramic fastener 16 fixes the heat-insulating material 13 and the heat-resistant support 12 to the inner side of the top of the furnace body 1 .
[0031] At the same time, the transverse cross-section of the heat-resistant support member 12 is U-shaped, and its size is adapted to the top of the furnace body 1 to facilitate the laying and positioning of the heat insulation material 13, improve the installation tightness and reliability, and further avoid heat loss. The heat-resistant support member 12 has good support properties, which can better compress the ceramic fiber cotton, making it tighter, thereby improving the heat insulation and heat preservation properties, and preventing the temperature in the furnace body 1 from being transmitted to the furnace top plate through its gaps, thereby better maintaining the temperature field stability in the furnace.
[0032] In this embodiment, the heat-resistant support member 12 is made of heat-resistant stainless steel to ensure the service life of the heat-resistant support member 12 .
[0033] In this embodiment, the inner wall of the top of the furnace body 1 is also covered with a partition piece 11, and the partition piece 11 is made of ceramic material. The ceramic fastener 16 sequentially passes through the partition piece 11 and the thermal insulation material 13 and fixes them on the inner wall of the top of the furnace body 1, so that the outer wall of the top of the furnace body 1 is in indirect contact with the heat-resistant support piece 12, further ensuring the thermal insulation effect of the furnace body 1.
[0034] In this embodiment, a slag discharge port 14 is provided on one side of the furnace body 1 , and a protective net 15 is provided on the outer side of the slag discharge port 14 to improve the aesthetics and safety.
[0035] Of course, the induced draft system 2 includes an induced draft fan 21 and a number of induced draft ducts 22 evenly distributed on the top of the furnace body 1 and connected to the air inlet of the induced draft fan 21. The smoke, hot air or other waste gas in the furnace body 1 is extracted through the induced draft fan 21 to maintain a negative pressure or a constant gas flow state in the furnace body 1, thereby ensuring the combustion efficiency and heat exchange efficiency of the furnace body 1.
[0036] In addition, the air inlet of the induced draft fan 21 is connected to a main duct 23. One end of the induced draft duct 22 is connected to the inside of the furnace body 1, and the other end is connected to the main duct 23, which can protect the working environment in the furnace body 1 from pollution.
[0037] Example 2
[0038] like Figure 6 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:
[0039] The protective net 15 is fixed to the furnace body 1 by a number of bolts 17, and the bolts 17 are respectively installed at the four corners of the protective net 15, thereby ensuring the stability of the protective net 15. When the staff passes by, the protective net 15 will not be affected and fall off. When slag discharge is required, it is only necessary to directly remove the bolts 17 and then take out the protective net 15. It is simple to operate and easy to use.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
