Description

Technical Field

[0001] The utility model relates to the technical field of exhaust devices, in particular to an exhaust device for a fully electric melting furnace in the production of solar vacuum tubes. Background Art

[0002] In the production process of solar vacuum tubes, as a key device, the fully electric melting furnace not only undertakes the task of material melting, but also involves the requirements of environmental protection and work safety. The exhaust device is an indispensable part of the fully electric melting furnace. Its main function is to effectively treat the waste gas generated during the melting process, ensure the smooth progress of the production process and the health and safety of operators. By reasonably configuring the exhaust pipe and the fan, ensuring the smooth discharge of gas, it can avoid excessive air pressure inside the melting furnace, thereby ensuring the stability of the melting process and the quality of products. In addition, a good exhaust system can also improve the energy utilization efficiency, reduce energy consumption, and further reduce production costs.

[0003] When the exhaust device of the fully electric melting furnace for the production of solar vacuum tubes is in use, most of them use HEPA filters and activated carbon filters, which can effectively capture fine particles and volatile organic compounds. However, when these filters are installed, they are usually installed inside the exhaust device, resulting in a large amount of time-consuming disassembly and installation when maintaining and repairing the filters, thus affecting the working efficiency of the melting furnace. Therefore, this problem needs to be solved. Summary of the Utility Model

Through the arrangement of the piston plate, the first rubber pad can be moved.

[0008] As a further solution of the present utility model, the pressing mechanism includes two connecting rods. The two connecting rods are both fixedly connected to the top of the piston plate, and the two connecting rods are both slidably connected to the top of the piston chamber. The tops of the two connecting rods are fixedly connected with the same pressing plate. An extrusion plate is sleeved on the surface of one side of the rotating shaft close to the pressing plate.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Since the present utility model adopts the technical solution of segmentally connecting the exhaust pipe and the docking pipe, the filter can be quickly inspected and maintained, thus effectively solving the problem that it is usually installed inside the exhaust device, resulting in a large amount of time being consumed for disassembly and installation when overhauling and maintaining the filter, thereby affecting the working efficiency of the melting furnace.

The plurality of ventilation holes 104 are all provided on one side inside the storage groove 103. The plurality of ventilation holes 104 are evenly arranged in a ring shape. The same ventilation groove 105 is provided on the surface of the plurality of ventilation holes 104 away from the docking groove 102. A piston chamber 106 is fixedly connected to the surface of the exhaust pipe 1 close to the ventilation groove 105. The piston chamber 106 and the ventilation groove 105 are arranged in a mutually communicating manner. A piston plate 107 is slidably connected inside the piston chamber 106. A pressing mechanism for pressing the piston plate 107 is provided on the top of the piston plate 107. Through the setting of the piston plate 107, the first rubber pad 2 can be moved.

[0023] Refer to Figure 4 and Figure 6 , In a preferred embodiment, the pressing mechanism includes two connecting rods 108. The two connecting rods 108 are both fixedly connected to the top of the piston plate 107, and the two connecting rods 108 are both slidably connected to the top of the piston chamber 106. The same pressing plate 109 is fixedly connected to the top of the two connecting rods 108. An extrusion plate 403 is sleeved on the surface of the rotating shaft 402 close to the pressing plate 109. The extrusion plate 403 and the pressing plate 109 are arranged in a cooperative manner. Two springs 110 are symmetrically and fixedly connected to the bottom of the piston plate 107. The bottom ends of the two springs 110 are both fixedly connected to one side inside the ventilation groove 105. A reset mechanism for resetting the first rubber pad 2 is provided inside each of the plurality of ventilation holes 104. Through the setting of the extrusion plate 403, the piston plate 107 can be pressed.

[0024] Refer to Figure 4 and Figure 5, in a preferred embodiment, the reset mechanism includes a telescopic cylinder 201. The telescopic cylinder 201 is fixedly connected to one side of the first rubber pad 2, and the other end of the telescopic cylinder 201 is fixedly connected to one side inside the ventilation groove 105. A tension spring 202 is sleeved on the surface of the telescopic cylinder 201. One end of the tension spring 202 is fixedly connected to one side inside the ventilation groove 105, and the other end of the tension spring 202 is fixedly connected to one side of the first rubber pad 2. Fixed blocks 404 are fixedly connected to the bottom sides of both the exhaust pipe 1 and the docking pipe 4, and the two fixed blocks 404 are arranged in a mutually cooperating manner. Through the arrangement of the tension spring 202, the first rubber pad 2 can be reset.

[0025] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: When it is necessary to install the filter 3, the filter 3 can be placed between the exhaust pipe 1 and the docking pipe 4. A docking groove 102 is provided on one side of the exhaust pipe 1, and the filter 3 can be docked through the docking groove 102 so that it can be accurately connected to the exhaust pipe 1 and the docking pipe 4. After the filter 3 is placed, the docking pipe 4 can be reset. A second rubber pad 401 is installed on one side of the docking pipe 4. Initially, the second rubber pad 401 protrudes from the docking pipe 4, but the two sides of the second rubber pad 401 are arranged in an arc shape. Therefore, when the second rubber pad 401 contacts the filter 3, the filter 3 will squeeze the second rubber pad 401, so that the docking pipe 4 can be docked with the filter 3. After the docking is completed, since the second rubber pad 401 is in a compressed state, it is possible to avoid leakage at the connection. An extrusion plate 403 is also installed on one side of the docking pipe 4, and a pressing plate 109 is provided at the bottom of the extrusion plate 403. Thus, when the extrusion plate 403 rotates with the docking pipe 4, the extrusion plate 403 will squeeze the pressing plate 109, causing it to move downward. A piston plate 107 is also installed at the bottom of the pressing plate 109. Therefore, the piston plate 107 will also move downward with the pressing plate 109. The piston plate 107 slides inside the piston chamber 106. An air vent groove 105 is provided at the bottom of the piston chamber 106, and the air vent groove 105 communicates with the air vent hole 104 on one side of the first rubber pad 2. Thus, when the piston plate 107 moves downward inside the piston chamber 106, air can be inflated into the air vent groove 105. Since the first rubber pad 2 is connected to the air vent groove 105 through the air vent hole 104, when the piston plate 107 inflates the air vent groove 105, the gas inside the air vent groove 105 will also simultaneously squeeze the first rubber pad 2, causing it to move synchronously. After the first rubber pad 2 moves, it will closely contact the other side of the filter 3, thus avoiding leakage on the other side of the filter 3. Fixed blocks 404 are installed at the bottoms of both the exhaust pipe 1 and the docking pipe 4. After the docking is completed, the two can be connected by bolts. When it is necessary to inspect and maintain the filter 3, only the docking pipe 4 needs to be rotated, which can greatly reduce the time required for inspection and maintenance.
