Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, and in particular to a sealing device for the opening of a drying furnace in chemical formation production. Background Technology

[0002] Drying ovens are widely used in industrial production. During operation, they remove moisture from materials to prevent it from affecting chemical reactions or causing product quality degradation, such as clumping and unstable performance. In chemical formation processes, drying ovens are used to dry the surface moisture of foils. However, in existing drying ovens, the oven openings are often left open for extended periods, leading to significant heat loss and the entry of dust and impurities. This results in unstable operation of the drying oven, which in turn affects the quality and efficiency of chemical formation production. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a sealing device for the drying furnace mouth in chemical formation production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sealing device for a drying furnace opening in a chemical production process includes a drying furnace body. A left limiting post and a right limiting post are vertically fixed to the left and right ends of the upper surface of the drying furnace body, respectively. Nuts are nested on the upper outer sides of both the left and right limiting posts. A secondary connecting plate is nested on the outer side of the left limiting post, and a main connecting plate is nested on the outer side of the right limiting post. A pull rod is fixed to the rear end of the upper surface of the main connecting plate. Embedded posts are vertically fixed to the front and rear ends inside the secondary connecting plate and the main connecting plate. Sealing plates are tightly attached to the front and rear ends of the upper surface of the drying furnace body.

[0006] Preferably, the left and right limiting posts are symmetrically arranged at the left and right ends of the opening in the middle of the drying furnace body, and the two sealing plates are symmetrically arranged at the front and rear ends of the opening in the middle of the sealing plates.

[0007] Preferably, the embedded posts at the front and rear ends of the bottom of the secondary connecting plate are embedded inside the left side of the sealing plate, and the embedded posts at the front and rear ends of the bottom of the main connecting plate are embedded inside the right side of the sealing plate.

[0008] Preferably, both sealing plates are tightly attached to the upper surface of the drying furnace body, and the sealing plates are made of mica plates.

[0009] Preferably, the nut is connected to the outer walls of the left and right limiting posts by threads, and the bottom of the nut is in close contact with the upper surfaces of the auxiliary connecting plate and the main connecting plate.

[0010] During use, this utility model can effectively seal the furnace opening of the drying furnace, preventing heat loss and the entry of external dust and impurities, maintaining a dry and stable process environment inside the furnace, improving the quality and efficiency of chemical formation production, and also achieving the goal of energy conservation and environmental protection.

[0015] Drying furnace body 1, left limiting post 2, right limiting post 3, nut 4, secondary connecting plate 5, main connecting plate 6, tie rod 601, embedded post 7, sealing plate 8. Detailed Implementation

[0016] Example 1, referring to Figure 1-3 A sealing device for a drying furnace opening in a chemical production process includes a drying furnace body 1. The device is characterized in that a left limiting post 2 and a right limiting post 3 are vertically fixed to the left and right ends of the upper surface of the drying furnace body 1, respectively. Nuts 4 are nested above the outer sides of both the left and right limiting posts 2 and 3. A secondary connecting plate 5 is nested outside the left limiting post 2, and a main connecting plate 6 is nested outside the right limiting post 3. A pull rod 601 is fixed to the rear end of the upper surface of the main connecting plate 6. Embedded posts 7 are vertically fixed to the front and rear ends of both the secondary connecting plate 5 and the main connecting plate 6. Sealing plates 8 are tightly attached to the front and rear ends of the upper surface of the drying furnace body 1.

[0017] The left limiting post 2 and the right limiting post 3 are symmetrically arranged at the left and right ends of the opening in the middle of the drying furnace body 1, and the two sealing plates 8 are symmetrically arranged at the front and rear ends of the opening in the middle of the sealing plate 8.

[0018] The embedded posts 7 at the bottom front and rear ends of the secondary connecting plate 5 are embedded inside the left side of the sealing plate 8, and the embedded posts 7 at the bottom front and rear ends of the main connecting plate 6 are embedded inside the right side of the sealing plate 8.

[0019] The main function of the embedded column 7 is to allow the auxiliary connecting plate 5 and the main connecting plate 6 to pull the sealing plate 8 to rotate normally during rotation;

[0020] When the foil enters the drying oven opening, manually pull the lever 601 on the main connecting plate 6 so that the main connecting plate 6 rotates around the right limit post 3. At this time, the two sealing plates 8 will simultaneously move towards the center of the drying oven opening, and the sealing plates 8 will also pull the auxiliary connecting plate 5 to rotate around the left limit post 2.

[0021] Both sealing plates 8 are tightly attached to the upper surface of the drying furnace body 1, and the sealing plates 8 are made of mica plates;

[0022] When the sealing plate 8 is tightly attached to the upper surface of the drying furnace body 1, it can prevent heat from escaping from the gap between the upper surface of the drying furnace body 1 and the bottom of the sealing plate 8, and can also prevent external dust or impurities from entering the drying furnace along the gap between the upper surface of the drying furnace body 1 and the bottom of the sealing plate 8.

[0023] Example 2 differs from Example 1 in that, in this example, the nut 4 is connected to the outer walls of the left limiting post 2 and the right limiting post 3 by threads, and the bottom of the nut 4 is in close contact with the upper surfaces of the auxiliary connecting plate 5 and the main connecting plate 6.

[0024] By unscrewing nut 4 from above the left limiting post 2 and right limiting post 3, the auxiliary connecting plate 5 and main connecting plate 6 can be pulled out from above the left limiting post 2 and right limiting post 3. Subsequently, the sealing plate 8 below the auxiliary connecting plate 5 and main connecting plate 6 can be cleaned and replaced.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
