Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment devices, in particular to a heat treatment device for zinc oxide production raw materials. Background Art

[0002] In the heat treatment process of zinc oxide resistors, a zinc oxide resistor heat treatment furnace is usually used to provide high temperature for the zinc oxide resistors for heat treatment.

An air inlet is respectively provided on the top and side walls of the furnace body, the first blower is provided on the top air inlet, the second blower is provided on the side wall air inlet, the first heating element is located above the furnace body and corresponds to the first blower, the second heating element is located on the side of the furnace body and corresponds to the second blower, the first windshield and the second windshield are fixed inside the furnace body and located on both sides below the first heating element, the second windshield and the third windshield are fixed inside the furnace body and located on both sides of the second heating element, and the material rack is located below the first heating element and corresponds to the second heating element. Although this heat treatment device can heat the zinc oxide resistor uniformly. However, the position of the heating element in this heat treatment device is fixed or the adjustment method is limited, resulting in low heat energy transfer efficiency. In particular, when processing smaller-sized zinc oxide raw materials, heat is easily lost during the transmission process, affecting the heating efficiency. In addition, this heat treatment device is a fixed configuration, and the position of the heating element cannot be flexibly adjusted according to the different sizes and shapes of the processed materials. This limits the ability of the furnace to process different products and reduces the applicability and economic benefits of the equipment. Since the position of the heating element is fixed and difficult to adjust, it is impossible to effectively adjust the position of the heating element according to the specific situation of the raw material during the heat treatment process. As a result, the heating of the zinc oxide raw material may be uneven, affecting product quality and processing effects. Therefore, improvements are needed. Utility Model Content

The support feet can be fixed by welding or bolting to enhance the stability and bearing capacity of the structure. A furnace opening 2 is opened on the surface of the furnace body 1 to facilitate the placement and removal of raw materials. A furnace door 3 is rotatably connected to the surface of the furnace body 1, which is connected by a hinge or a rotating shaft to achieve convenient opening and closing. A sliding rod 4 is provided through the side of the furnace body 1, and the sliding rod 4 is slidably connected to the furnace body 1 through a bearing or a sliding support to ensure smooth sliding without obstruction. A mounting plate 5 is fixedly installed at one end of the sliding rod 4, and this fixing method can be welded or bolted to provide solid support. A heating element 7 is fixedly installed on the side of the mounting plate 5, and the fixing can be achieved by clamping or threaded connection to ensure that the heating element 7 is stable and reliable in a high temperature environment, and the heating element 7 can be heated by an electric heating tube. A connecting block 6 is fixedly mounted on the other end of the slide rod 4, and can also be fixed by welding or bolts.

[0027] See also Figure 1-6 , a spring 8 is sleeved on the surface of the slide rod 4, one end of the spring 8 is fixedly connected to the connecting block 6, and the other end is fixedly connected to the furnace body 1, which can be achieved by welding or clamping. The spring 8 is a compression spring, which provides the necessary restoring force to ensure that the heating element 7 automatically returns to its original position when there is no operation. A side groove 9 is provided on the side of the furnace body 1, and a screw rod 10 is provided through the inner wall of the side groove 9. The inner wall of the side groove 9 is provided with a thread, and the thread is engaged with the screw rod 10. An adjustment cap 12 is fixedly installed at the bottom end of the screw rod 10, and an anti-slip groove 13 is provided on the surface of the adjustment cap 12 to provide a good grip and rotation experience for the operator. The adjustment cap 12 can be made of plastic or metal to adapt to different working environments. The top of the screw rod 10 is rotatably connected with a push block 11, and the push block 11 is slidably connected to the inner wall of the furnace body 1. This connection can be supported by a guide rail or a roller. When the furnace door 3 is closed, the furnace door 3 can squeeze the connecting plate 16, and the connecting plate 16 rotates through the rotating rod 15 to realize the action of the warning sign 17.

[0028] Embodiment 2

[0029] See also Figure 5-6, a warning mechanism is provided on the top surface of the furnace body 1, and the warning mechanism includes a top groove 14, and the top groove 14 is opened on the top surface of the furnace body 1. A rotating rod 15 is rotatably connected to the inner side of the top groove 14, and a connecting plate 16 is fixedly installed on the surface of the rotating rod 15. A warning sign 17 is fixedly installed on the top of the connecting plate 16. A torsion spring 19 is sleeved on the surface of the rotating rod 15. When the furnace door 3 is closed, the furnace door 3 can squeeze the connecting plate 16, and the connecting plate 16 can be rotated by the rotating rod 15 at this time, and the connecting plate 16 can then drive the warning sign 17 to rotate. After the furnace door 3 is completely closed, the warning sign 17 can stand up at this time, thereby alerting the staff to pay attention. When the furnace door 3 is opened, due to the loss of squeezing of the connecting plate 16, due to the torsion of the torsion spring 19, the torsion spring 19 can drive the connecting plate 16 to rotate until the connecting plate 16 and the warning sign 17 are placed flat, and the warning sign 17 can be put away at this time. One end of the torsion spring 19 is fixedly connected to the connecting plate 16, and the other end of the torsion spring 19 is fixedly connected to the inner wall of the top groove 14. The connection method can be specifically screwed, welded or riveted, which can ensure that the torsion spring 19 will not loosen due to material expansion in a high temperature environment, ensuring safe operation. The surface of the connecting plate 16 is provided with a rounded corner 18, which can prevent the operator from being scratched by sharp corners during use, improve the ergonomic safety of the equipment, and the rounded corner 18 can improve the smooth transition, making the furnace door 3 smoother when squeezed.

[0030] Working principle: open the furnace door 3, and then put the zinc oxide raw material that needs to be heat treated into the furnace body 1, and then close the furnace door 3, and then the zinc oxide raw material can be heated by the heating element 7, so as to perform heat treatment on the zinc oxide raw material. When heat treating some smaller zinc oxide raw materials, the staff can screw the screw rod 10 through the adjusting cap 12. At this time, since the inner wall of the side groove 9 is provided with threads, the screw rod 10 moves upward at this time, and the screw rod 10 can then drive the push block 11 to move upward. The push block 11 then slides synchronously on the inner wall of the furnace body 1. During the upward sliding process of the push block 11, the inclined surface of the surface of the push block 11 can squeeze the mounting plate 5 to move, and the mounting plate 5 can then drive the heating element 7 to move, so that the heating element 7 can be brought closer to the zinc oxide raw material. In this way, when facing smaller zinc oxide raw materials, the heating element 7 can be brought closer, thereby improving efficiency. When heating some larger-sized zinc oxide raw materials, the staff only needs to twist the adjusting cap 12 in the opposite direction to move the screw rod 10 downward. When the push block 11 moves downward, a gap can be left between the push block 11 and the mounting plate 5. At this time, due to the elastic force of the spring 8, the spring 8 can drive the connecting block 6 to move, and the connecting block 6 then drives the slide bar 4 to move, and the slide bar 4 then drives the mounting plate 5 to move. At this time, the mounting plate 5 drives the heating element 7 to move toward the inner wall of the furnace body 1, thereby making enough space to put in larger-sized zinc oxide raw materials. The utility model can more effectively adjust the heating element 7 to a position closer to the small-sized zinc oxide raw materials. The heat energy is transferred to the furnace body 1, and the heat loss in the transmission process is reduced, thereby improving the overall heating efficiency. This allows the operator to flexibly adjust the position of the heating element 7 according to the size of the processed material. This flexibility enables the furnace body 1 to process zinc oxide raw materials of different sizes and shapes, enhancing the applicability and economic benefits of the equipment. The position of the heating element 7 can be adjusted according to the specific conditions of the raw materials, which helps to achieve more uniform heating. When the furnace door 3 is closed, the furnace door 3 can squeeze the connecting plate 16, and the connecting plate 16 can be rotated by the rotating rod 15 at this time. The connecting plate 16 can then drive the warning sign 17 to rotate. After the furnace door 3 is completely closed, the warning sign 17 can stand up at this time to alert the staff to pay attention. When the furnace door 3 is opened, due to the connecting plate 16, the connecting plate 16 can rotate by the rotating rod 15. The connecting plate 16 can then drive the warning sign 17 to rotate. After the furnace door 3 is completely closed, the warning sign 17 can stand up at this time to alert the staff to pay attention. The connecting plate 16 loses its extrusion, and due to the torsion force of the torsion spring 19, the torsion spring 19 can drive the connecting plate 16 to rotate until the connecting plate 16 and the warning sign 17 are laid flat, at which time the warning sign 17 can be folded up. The utility model automatically puts up the warning sign 17 when the furnace door 3 is closed, clearly indicating to the operator that the furnace door 3 has been safely closed, thereby avoiding misoperation when the furnace door 3 may not be completely closed, thereby improving operational safety. The automatic pop-up and retraction of the warning sign 17 provides an intuitive visual prompt for the operation process, helping the staff to quickly identify the status of the furnace door 3 and enhancing safety management in the workplace. The automatic warning sign 17 reduces the need to rely on manual setting of warning signs, thereby reducing safety accidents that may occur due to forgetting to set the warning sign 17.
