[0001] The utility model relates to the technical field of resistance furnaces, in particular to a box-type resistance furnace with a hot air circulation function. Background Technique

[0002] A resistance furnace is a device that uses an electric current passing through a resistance element to generate heat to heat an object, and is widely used in multiple fields. At present, the heat of the resistance furnace is easily dissipated outward, increasing energy waste.

[0003] In the patent application with the publication number of CN202692683U in the prior art, a resistance furnace is disclosed, including a furnace body. The sealing effect of the furnace body is good, which can prevent a large amount of heat loss and reduce energy waste.

[0004] However, in the prior art, the hot air in the furnace body does not circulate, which easily leads to uneven temperature in the furnace body and reduces the practicability of the device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a box-type resistance furnace with a hot air circulation function, aiming to solve the problem that in the prior art, the hot air in the furnace body does not circulate, which easily leads to uneven temperature in the furnace body and reduces the practicability of the device.

[0006] To achieve the above purpose, the utility model provides a box-type resistance furnace with a hot air circulation function, including a furnace body and a ventilation mechanism. The ventilation mechanism includes an expansion air pipe, an installation cylinder, a driving component, an installation disc, six connecting components, six fan blades and two air guide pipes. The expansion air pipe is fixedly connected to the lower side wall of the furnace body and is communicated therewith. The installation cylinder is fixedly connected to the expansion air pipe and is communicated therewith. The driving component is arranged on the installation cylinder. The installation disc is arranged on the driving component and is located inside the installation cylinder. The six fan blades are respectively detachably connected to the installation disc through the six connecting components. One ends of the two air guide pipes are respectively fixedly connected to both ends of the furnace body, and the other ends of the two air guide pipes are respectively fixedly connected to both ends of the installation cylinder and are communicated therewith.

[0007] Among them, the driving component includes a driving motor and a driving shaft. The driving motor is fixedly connected to the installation cylinder and is located below the installation cylinder. The driving shaft is fixedly connected to the output end of the driving motor and extends into the installation cylinder. The installation disc is fixedly connected to the driving shaft.

[0008] Among them, the driving component further includes a fixing frame. The fixing frame is fixedly connected to the installation cylinder and is located inside the installation cylinder. The driving shaft is rotatably connected to the fixing frame and penetrates through the fixing frame.

[0009] Wherein, the connection component includes a mounting block and a bolt. The mounting disc has six mounting grooves. The mounting block is fixedly connected to the fan blade and is located within the mounting groove. The bolt is threadedly connected to the mounting block and the mounting disc.

[0010] Wherein, the ventilation mechanism further includes a baffle. The baffle has a plurality of air guide holes. The baffle is fixedly connected to the furnace body and is located within the furnace body.

[0011] Wherein, the box-type resistance furnace with a hot air circulation function further includes a thermometer. The thermometer is fixedly connected to the furnace body.

[0012] In a box-type resistance furnace with a hot air circulation function of the present utility model, when the resistance furnace is operating, the temperature inside the furnace body rises. At this time, the drive component is started. The drive component drives the mounting disc and the six fan blades to rotate at high speed. The six fan blades rotating at high speed generate an air flow. The air flow enters the furnace body through the expansion air duct. The expansion air duct makes the air flow evenly blow into the furnace body. The air flow blows into the furnace body, causing the high-temperature air inside the furnace body to flow inside the furnace body. The high-temperature air follows the air flow and flows upward, and the air flow drives the high-temperature air into the two air guide pipes. The two air guide pipes then introduce the high-temperature air into the mounting cylinder. The high-temperature air is again introduced into the furnace body by the high-speed rotation of the six fan blades. The high-temperature air circulates inside the furnace body, the mounting cylinder, and the two air guide pipes, thereby making the temperature inside the furnace body more balanced and increasing the practicality of the device.

[0021] Please refer to Figures 1 to 6 , wherein, Figure 1 It is a schematic structural diagram of the box-type resistance furnace with a hot air circulation function of the present utility model, Figure 2 It is a side view of the box-type resistance furnace with a hot air circulation function of the present utility model, Figure 3 It is of the present utility model Figure 2 Cross-sectional view taken along line A-A of Figure 4 It is a schematic structural diagram inside the furnace body of the box-type resistance furnace with a hot air circulation function of the present utility model, Figure 5 It is a schematic structural diagram inside the mounting cylinder of the box-type resistance furnace with a hot air circulation function of the present utility model, Figure 6 It is a schematic structural diagram of the mounting plate of the box-type resistance furnace with a hot air circulation function of the present utility model.

[0022] The present utility model provides a box-type resistance furnace with a hot air circulation function, including a thermometer 113, a furnace body 101 and a ventilation mechanism. The ventilation mechanism includes an air expansion pipe 102, a mounting cylinder 103, a baffle plate 114, a driving assembly, a mounting plate 106, six connecting components, six fan blades 108 and two air guide pipes 112. The driving assembly includes a fixing frame 109, a driving motor 104 and a driving shaft 105. The connecting component includes a mounting block 107 and a bolt 110. The mounting plate 106 has six mounting grooves 111. The baffle plate 114 has a plurality of air guide holes 115. Through the foregoing solution, the problem in the prior art that the hot air in the furnace body 101 does not circulate, easily leads to uneven temperature in the furnace body 101, and reduces the practicability of the device is solved. It can be understood that the six fan blades 108 can be installed and disassembled through the six connecting components for easy repair and maintenance.

[0023] In this embodiment, the air expansion duct 102 is fixedly connected to the lower side wall of the furnace body 101 and is in communication therewith. The installation cylinder 103 is fixedly connected to the air expansion duct 102 and is in communication therewith. The driving assembly is arranged on the installation cylinder 103. The installation disc 106 is arranged on the driving assembly and is located inside the installation cylinder 103. The six fan blades 108 are respectively detachably connected to the installation disc 106 through six connection components. One ends of the two air guide pipes 112 are respectively fixedly connected to both ends of the furnace body 101, and the other ends of the two air guide pipes 112 are respectively fixedly connected to both ends of the installation cylinder 103 and are in communication therewith. When the resistance furnace works, the temperature inside the furnace body 101 rises. At this time, the driving assembly is started, and the driving assembly drives the installation disc 106 and the six fan blades 108 to rotate at high speed. The six fan blades 108 rotate at high speed to generate air flow, and the air flow enters the furnace body 101 through the air expansion duct 102. The air expansion duct 102 makes the air flow evenly blow into the furnace body 101. The air flow blows into the furnace body 101, causing the high-temperature air inside the furnace body 101 to flow inside the furnace body 101. The high-temperature air follows the air flow and flows upward, and the air flow drives the high-temperature air into the two air guide pipes 112. The two air guide pipes 112 then introduce the high-temperature air into the installation cylinder 103. The high-temperature air is again added to the furnace body 101 through the high-speed rotation of the six fan blades 108. The high-temperature air circulates inside the furnace body 101, the installation cylinder 103 and the two air guide pipes 112, thereby making the temperature inside the furnace body 101 more balanced and increasing the practicability of the device.

[0024] Further, the driving motor 104 is fixedly connected to the installation cylinder 103 and is located below the installation cylinder 103. The driving shaft 105 is fixedly connected to the output end of the driving motor 104 and extends into the installation cylinder 103. The installation disc 106 is fixedly connected to the driving shaft 105.

[0025] Further, the fixing frame 109 is fixedly connected to the installation cylinder 103 and is located inside the installation cylinder 103. The driving shaft 105 is rotatably connected to the fixing frame 109 and penetrates through the fixing frame 109.

[0026] In this embodiment, when the resistance furnace works, the temperature inside the furnace body 101 rises. At this time, the driving motor 104 is started. The driving motor 104 drives the driving shaft 105 and the installation disc 106 to rotate. The six fan blades 108 rotate at high speed following the installation disc 106. The air flow enters the furnace body 101 through the air expansion duct 102. The fixing frame 109 plays a role in limiting the driving shaft 105, ensuring that the driving shaft 105 does not tilt and remains vertical, and increasing the stability of the driving shaft 105 during rotation.

[0027] Further, the mounting disc 106 has six mounting grooves 111. The mounting block 107 is fixedly connected to the fan blade 108 and is located within the mounting grooves 111. The bolt 110 is threadedly connected to the mounting block 107 and the mounting disc 106.

[0028] In this embodiment, when installing the fan blade 108, the mounting block 107 is inserted into the mounting grooves 111, and then the mounting block 107 and the mounting disc 106 are fixed together by the bolt 110. The fan blade 108 can be easily installed and disassembled, facilitating the repair and maintenance of the device in the later stage.

[0029] Further, the baffle 114 is fixedly connected to the furnace body 101 and is located within the furnace body 101. A plurality of air guide holes 115 are uniformly arranged on the baffle 114.

[0030] In this embodiment, the air flow is introduced into the furnace body 101 through the expanding air duct 102. The expanding air duct 102 enables the air flow to be evenly blown into the furnace body 101. When the air flow is blown into the furnace body 101, since the air guide holes 115 are evenly distributed on the baffle 114, when the air flow passes through the plurality of air guide holes 115 on the baffle 114, the air flow is blown into the furnace body 101 more evenly.

[0031] Further, the thermometer 113 is fixedly connected to the furnace body 101.

[0032] In this embodiment, the operator can visually observe the temperature change within the furnace body 101 through the thermometer 113, facilitating the operator to judge the situation within the furnace body 101.

[0033] When heating using the present utility model, the temperature inside the furnace body 101 rises. At this time, the drive motor 104 is started, and the drive motor 104 drives the drive shaft 105 and the mounting plate 106 to rotate. The six fan blades 108 rotate at high speed following the mounting plate 106. Airflow is added into the furnace body 101 through the air expansion pipe 102. The fixing frame 109 plays a role in limiting the drive shaft 105 to ensure that the drive shaft 105 does not tilt and remains vertical. The air expansion pipe 102 enables the airflow to be evenly blown into the furnace body 101. When the airflow blows into the furnace body 101, since the air guide holes 115 are evenly distributed on the baffle plate 114, when the airflow passes through the multiple air guide holes 115 on the baffle plate 114, the airflow is blown into the furnace body 101 more evenly, causing the high-temperature air inside the furnace body 101 to flow inside the furnace body 101. The high-temperature air follows the airflow and flows upward, and the airflow drives the high-temperature air into the two air guide pipes 112. The two air guide pipes 112 then introduce the high-temperature air into the mounting cylinder 103. The high-temperature air is again added into the furnace body 101 through the high-speed rotation of the six fan blades 108. The high-temperature air circulates inside the furnace body 101, the mounting cylinder 103, and the two air guide pipes 112, thereby making the temperature inside the furnace body 101 more balanced and increasing the practicality of the device.

[0034] The above disclosure is only a preferred embodiment of the present application and cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand the entire or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
