Description

Technical Field

[0001] The present invention belongs to the technical field of low-temperature resistance furnaces, and particularly relates to a heat dissipation device for a low-temperature resistance furnace. Background Art

[0002] With the development and progress of technology, people's requirements for things have changed from the old thinking of just being able to use them to being quite delicate and demanding. Only by constantly making progress or having innovative ideas to create new forms to increase the added value of products can one survive the severe test of fierce market competition.

[0003] Compared with heating furnaces with relatively low heating temperatures, it is very difficult to achieve the furnace temperature uniformity required by the process in a short time with traditional heating methods. Especially, the temperature at the top inside the heating furnace is relatively low. Due to the structure of the top, most resistance furnaces cannot arrange heating belts at the top. Only by internal circulation can the heat at the bottom and sides of the heating furnace be brought to the top to increase the top temperature. However, a large amount of data shows that the top temperature is still lower than that of the bottom and sides. The main reason for the low top temperature is that there is no heating belt at the top. Also, the heating belts inside the resistance furnace are directly fixed on the heating furnace shell, and there is heat insulation cotton installed between the furnace shell and the heating belt. When installing, workers must enter the heating furnace to operate. The number of fixing parts between the heating belt and the furnace shell is at least several hundred and at most several thousand. That is to say, a corresponding number of round holes also need to be opened on the heat insulation cotton. These round holes have a great impact on the heat insulation effect of the heating furnace, resulting in serious heat loss of the furnace temperature. The installation and fixation of the heating belt also need to be completed inside the furnace, which is rather difficult for workers to operate. If the fixing rod of the heating belt breaks, workers have to enter the furnace to replace the new fixing rod. If the heating belt fails, it is even more troublesome to replace. The heating belt must be removed from the fixing rod and taken out of the furnace for repair or replacement. Due to the huge number of fixing points, it is time-consuming and laborious. Summary of the Invention

[0004] Aiming at the problems raised in the above background art, the purpose of the present invention is to provide a heat dissipation device for a low-temperature resistance furnace.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0007] Further defined, the clamping seat is matched with a clamping plate. With such a design, the air duct can be protected after being matched with the clamping seat.

[0008] Further defined, there are at least four groups of air ducts, two in each group, evenly distributed on the left and right sides of the furnace body. With such a design, the air supply effect is guaranteed.

[0009] Further defined, the air duct is detachably connected with the clamping seat. With such a design, it is convenient to replace and repair the air duct.

[0010] Further defined, ear plates are provided at the bottom of the furnace body, and an outer cover installed on the ear plates is matched with the furnace body. With such a design, dust prevention and overall protection are achieved.

[0011] Further defined, opening and closing doors are provided in both the first air chamber and the second air chamber. With such a design, it is convenient to clean the inside.

[0014] The beneficial effects of adopting the present invention:

[0015] 1.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 5As shown in the figure, a heat dissipation device for a low-temperature resistance furnace of the present invention includes a base 1 and a furnace body 2 installed on the base 1. Clamps 3 are provided on the left and right outer sides of the furnace body 2. A number of air ducts 4 are installed on the clamps 3. A first air chamber 5 communicating with the air ducts 4 is provided below the clamps 3. The input end of the first air chamber 5 is connected to an air pump, and the air pump is installed at the rear side of the furnace body. A second air chamber 6 is provided at the bottom of the furnace body 2. The input end of the second air chamber 6 is communicated with the inside of the furnace body 2, and the output end of the second air chamber 6 is connected to the air pump. A wind box 7 is slidably matched with the top of the furnace body 2. A filter screen 8 is slidably matched with the wind box 7. Sliding grooves 9 are provided on both sides of the wind box 7. Transfer components 10 are slidably matched with the sliding grooves 9. The input end of the transfer component 10 is connected to the output end of the air duct 4. The transfer component 10 includes a ball head 101 matching the output end of the air duct 4. The ball head 101 is connected to a cylinder 102. The cylinder 102 is slidably matched with the sliding groove 9. A spring group 103 is connected between the cylinder 102 and the sliding groove 9. The cylinder 102 is connected to an air outlet pipe 104. An air duct 105 is provided between the ball head 101 and the air outlet pipe 104. An air chamber 11 connected to the output end of the transfer component 10 is provided inside the wind box 7. The air chamber 11 is located above the filter screen 8. A number of air outlets 12 are provided on the lower side of the wind box 7. The air outlets 12 are located in the heating area of the furnace body 2.

[0028] In this embodiment, when using a heat dissipation device for a low-temperature resistance furnace, the clamps 3 are installed on both sides of the furnace body 2, and then the wind box 7 is installed on the upper side of the furnace body 2, and each air duct is communicated. The air pump is started to inhale the hot air generated in the furnace into the first air chamber 6 through the second air chamber 6, and then into the air duct 4. The air in the air duct 4 is discharged into the air chamber 11 in the wind box 7 through the transfer component 10, and is discharged from the air outlet 12 to the top of the furnace after being filtered by the filter screen 8, directly blowing on the material, so that the temperature of the material at the top of the furnace is uniform, solving the problem of poor furnace temperature uniformity caused by the low temperature at the top before, reducing the maintenance work and improving the production efficiency. Moreover, after using for a period of time, the wind box 7 can be directly pulled out to clean and maintain the wind box 7 and the filter screen 8. The filter screen 8 is installed in a slidable matching manner, and can also be directly pulled out from the wind box 7. After cleaning, it can be directly pushed back to the original position. The transfer component 10 can automatically return to the original position for docking. Specifically, when the wind box 7 moves and the ball head 101 is stressed, the ball head 101 will push the cylinder 102 to move towards the position of the sliding groove 9, that is, to achieve the effect of not interfering with the movement of the wind box 7. When the wind box 7 is pushed back to the furnace body 2 in place, under the action of the spring group 103, the ball head 101 will enter the air duct 4 to achieve docking, ensuring that the air in the air duct 4 enters the air chamber 11 through the air duct 105.

[0029] Preferably, the clamp 3 is matched with a clamping plate 31. Such a design can protect the air duct 4 after being combined with the clamp 3. In fact, a structure that can protect the air duct 4 can also be considered according to specific situations.

[0030] Preferably, there are at least four groups of air ducts 4, with two in each group, evenly distributed on the left and right sides of the furnace body 2. Such a design ensures the air supply effect. In fact, the number of air ducts 4 can also be considered according to specific circumstances.

[0031] Preferably, the air duct 4 is detachably connected to the card seat 3. Such a design facilitates the replacement and maintenance of the air duct 4. In fact, the connection method between the air duct 4 and the card seat 3 can also be considered according to specific circumstances.

[0032] Preferably, the bottom of the furnace body 2 is provided with lugs 201, and the furnace body 2 is matched with an outer cover 202 installed on the lugs 201. Such a design prevents dust and protects the whole. In fact, measures for dust prevention and protection of the furnace body 2 can also be considered according to specific circumstances.

[0033] Preferably, both the first air chamber 5 and the second air chamber 6 are provided with opening and closing doors. Such a design facilitates the cleaning of the interior. In fact, methods for facilitating the cleaning of the interiors of the first air chamber 5 and the second air chamber 6 can also be considered according to specific circumstances.

[0034] Preferably, the ball head 101 and the cylinder 102 are integrally formed. Such a design is not prone to breakage problems. In fact, the connection method between the ball head 101 and the cylinder 102 can also be considered according to specific circumstances.

[0035] Preferably, the air box 7 is provided with two threaded holes 701. Such a design enables the air box 7 to be conveniently withdrawn by screwing in screws. In fact, measures for conveniently withdrawing the air box 7 can also be considered according to specific circumstances.
