Description

Technical Field

[0001] This utility model relates to the field of heat insulation curtain technology, specifically to a flexible heat insulation curtain and a bright solution furnace. Background Technology

[0002] A bright solution furnace is a device used for heat treatment of metallic materials. Both the heating chamber temperature range and the heating chamber inlet are insulated with heat-insulating curtains.

[0003] Traditional heat insulation curtains are suspended, one-piece flexible fabrics. Their top is connected to the inner wall of the heating chamber, while their bottom hangs naturally, adhering to the conveyor belt running through the heating zone. When metal materials enter different temperature zones under the action of the conveyor belt, the heat insulation curtain is lifted; after the metal materials have completely passed, the curtain returns to its natural hanging state. However, this type of heat insulation curtain, once lifted, cannot promptly adhere to the metal materials and conveyor belt, easily leading to rapid heat transfer from both sides of the curtain.

[0004] Therefore, it is necessary to improve the structure of the heat insulation curtain in the existing technology. Utility Model Content

[0005] In view of the above-mentioned prior art, one of the objectives of this utility model is to provide a flexible heat insulation curtain that can maintain a good heat insulation effect when materials pass through it.

[0006] To achieve the above objectives, the technical solution of this utility model is: a flexible heat insulation curtain, comprising:

[0007] The upper curtain body has a hanging top edge;

[0008] The lower curtain body is fixedly connected to the bottom edge of the upper curtain body, and includes a first curtain body and a second curtain body located in the material conveying direction of the first curtain body;

[0009] The length of the first curtain is less than the length of the second curtain;

[0010] The first curtain has a bottom end that fits into the working surface of the material conveyor belt.

[0011] Preferably, in order to ensure that the bottom of the flexible heat insulation curtain fits into the material and the conveyor belt in a timely manner when the material passes through it, the bottom edge of the first curtain and / or the second curtain is a first bottom edge, and a first counterweight is provided at intervals along the extension direction of the first bottom edge.

[0012] Preferably, in order to accommodate materials of different specifications, the upper curtain and / or the first curtain are provided with second counterweights at intervals along the length direction, and the second counterweights are located above the first counterweights.

[0013] Preferably, to avoid friction between the first counterweight and the material, the first counterweight and / or the second counterweight are wrapped inside the upper curtain and / or the lower curtain.

[0014] Preferably, to avoid the first curtain and the second curtain being too close together, the first curtain is composed of a plurality of horizontally adjacent and / or overlapping strips of curtain, which are connected to the upper curtain.

[0015] Preferably, in order to accommodate materials of different specifications, the second curtain includes a length adjustment section.

[0016] Preferably, in order to provide an implementation of the second curtain length adjustment section, the length adjustment section is a pleated structure, and the pleated structure is removably provided with pleated clamping members.

[0017] Preferably, in order to enhance the sealing performance of the flexible heat insulation curtain, the upper curtain body and / or the lower curtain body include a furnace opening blocking part perpendicular to the material advancing direction, and a side wall abutment part located on the side of the furnace opening blocking part in the width direction.

[0018] Preferably, in order to ensure the durability of the flexible heat insulation curtain in high-temperature environments, both the upper and lower curtain bodies are made of high-temperature resistant asbestos cloth.

[0019] The second objective of this utility model is to provide a bright solution furnace, which includes the aforementioned flexible heat insulation curtain.

[0020] The advantages and beneficial effects of this utility model are as follows:

[0021] The flexible heat insulation curtain includes upper and lower curtains that are fixedly connected. The lower curtain includes a first curtain and a second curtain that is longer than the first curtain and located in the material conveying direction of the first curtain. When the material passes through the flexible heat insulation curtain, it first lifts up the first curtain, while the bottom end of the second curtain remains in contact with the conveyor belt. When the material contacts the second curtain and lifts up the second curtain, the bottom end of the first curtain is in contact with the material and / or the conveyor belt, resulting in less heat transfer on both sides of the flexible heat insulation curtain.

[0022] The flexible heat insulation curtain has a reasonable structure, low failure rate, and smooth operation. Attached Figure Description

Detailed Implementation

[0036] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, the flexible heat insulation curtain of Embodiment 1 includes: an upper curtain body 1 with a hanging top edge 101; a lower curtain body 2, which is fixedly connected to the bottom edge of the upper curtain body 1, including a first curtain body 201 and a second curtain body 202 located in the material conveying direction of the first curtain body 201; the length of the first curtain body 201 is less than the length of the second curtain body 202; the first curtain body 201 has a bottom end that fits against the working surface of the material conveyor belt.

[0039] Specifically, the suspended top edge 101 is used to abut and fix to the inner top wall of the heating chamber and / or the top wall of the heating chamber opening, and the curtain surfaces of the upper curtain 1 and the lower curtain 2 are parallel to the material conveying direction. When the heating chamber is working, the conveyor belt located at the bottom of the heating chamber delivers spaced materials from the heating chamber opening to the internal temperature zone of the heating chamber, and then inputs the heated materials into the next working section.

[0040] The working process of this flexible heat insulation curtain is as follows:

[0041] When no material passes through the flexible heat insulation curtain, the bottom end of the first curtain 201 is in contact with the conveyor belt; the length of the second curtain 202 is greater than the length of the first curtain 201, and the bottom end of the second curtain 202 is in contact with the conveyor belt. Under the action of the friction between the conveyor belt and itself, the bottom end of the second curtain 202 is in the material conveying direction of the bottom end of the first curtain 201; a gap is formed between the second curtain 202 and the first curtain 201.

[0042] When material passes through the flexible heat-insulating curtain, it first contacts the first curtain 201. The first curtain 201 is pushed away from the conveyor belt by the material, and part of the bottom edge of the first curtain 201 does not fall down in time and adhere to the conveyor belt and / or the material. At this time, due to the gap between the second curtain 202 and the first curtain 201, that is, the material has not yet come into contact with the second curtain 202, so there is little heat transfer on both sides of the second curtain 202. When the material comes into contact with the second curtain 202, the bottom edge of the first curtain 201 has fallen down and adhered to the conveyor belt and / or the material, while only part of the bottom edge of the second curtain 202 has not fallen down in time and adhered to the conveyor belt and / or the material, so there is still little heat transfer on both sides of the second curtain 202.

[0043] like Figures 3-5 As shown, the bright solution furnace includes a feeding section 6, a heating section 7, a cooling section 8, and a discharging section 9. The flexible heat insulation curtain is located inside the heating section 7 of the bright solution furnace, specifically within the heating chamber and at the inlet of the heating chamber.

[0044] Example 2

[0045] like Figure 6 and Figure 7 As shown, the flexible heat insulation curtain of Embodiment 2 is based on Embodiment 1, except that the bottom edge of the first curtain body 201 and / or the second curtain body 202 is the first bottom edge, and the first bottom edge is provided with first counterweights 3 at intervals along the extension direction.

[0046] Specifically, after the first counterweight 3 is set on the first bottom edge of the first curtain 201 and / or the second curtain 202, the first curtain 201 and / or the second curtain 202 will fall down faster and fit into the conveyor belt and / or the material after being pushed away from the conveyor belt by the material, and less heat will be transferred to both sides of the first curtain 201 and / or the second curtain 202.

[0047] Example 3

[0048] like Figure 8 and Figure 9 As shown, the flexible heat insulation curtain of Embodiment 3 is based on Embodiment 2, except that the curtain body 1 and / or the first curtain body 201 are provided with second counterweights 4 at intervals along the length direction, and the second counterweights 4 are located above the first counterweights 3.

[0049] Specifically, after the upper curtain 1 and / or the first curtain 201 are equipped with the second counterweight 4, when tall or long materials pass through the first curtain 201, the upper curtain 1 and / or the first curtain 201 always remain vertical to the conveyor belt. The curtain surface of the flexible heat insulation curtain is the heat transfer surface on both sides of the flexible heat insulation curtain. At this time, the heat transfer surface is small, and the heat transfer on both sides of the flexible heat insulation curtain is less. In addition, after the first curtain 201 is equipped with the second counterweight 4, when tall or long materials pass through the first curtain 201, the first curtain 201 is not easily driven by the materials to approach the second curtain 202, avoiding a small gap between the second curtain 202 and the first curtain 201. At this time, after the first curtain 201 is lifted by the materials, it has enough time to fall and fit with the conveyor belt and / or the materials.

[0050] Furthermore, the first counterweight 3 and / or the second counterweight 4 are enclosed within the upper curtain 1 and / or the lower curtain 2.

[0051] Specifically, at this time, the first counterweight 3 and / or the second counterweight 4 will not come into direct contact with the material, thus preventing the material from being scratched by the first counterweight 3 and / or the second counterweight 4.

[0052] Furthermore, both the upper curtain 1 and the lower curtain 2 are made of high-temperature resistant asbestos cloth.

[0053] Specifically, both the upper curtain 1 and the lower curtain 2 are made of high-temperature resistant asbestos cloth, which can meet the requirements for long-term operation in high-temperature environments.

[0054] Example 4

[0055] like Figure 10 As shown, the flexible heat insulation curtain of Embodiment 4 is based on Embodiment 1, except that the first curtain body 201 is composed of a plurality of strip curtain panels 2011 that are closely adjacent and / or overlapped in the horizontal direction, and the strip curtain panels 2011 are connected to the upper curtain body 1.

[0056] Specifically, when a higher material passes through the first curtain 201, since the first curtain 201 is composed of multiple horizontally adjacent and / or overlapping strips 2011, the first curtain 201 will not be pulled by the material and will approach the second curtain 202 as a whole. After the first curtain 201 is lifted by the material, it has enough time to fall and fit with the conveyor belt and / or the material.

[0057] Example 5

[0058] like Figure 11 As shown, the flexible heat insulation curtain of Embodiment 5 is based on Embodiment 1, except that the second curtain 202 includes a length adjustment section 2021.

[0059] Specifically, due to factors such as operating temperature, the material of the lower curtain 2, and the shape of the material, the time it takes for the first curtain 201 to fall and adhere to the material and / or conveyor belt when the material passes by is not fixed. The second curtain 202 includes a length adjustment section 2021. Adjusting the length adjustment section 2021 can adjust the gap between the first curtain 201 and the second curtain 202, thereby meeting the time requirement for the first curtain 201 to fall and adhere to the material and / or conveyor belt when the material passes by.

[0060] Furthermore, the length adjustment section 2021 has a pleated structure, and the pleated structure is removable and equipped with a pleated clamping member.

[0061] Specifically, the length adjustment section 2021 has a simple structure, and the pleated clamping component can be a high-temperature resistant clamp.

[0062] Example 6

[0063] like Figure 12 As shown, the flexible heat insulation curtain of Embodiment 6 is based on Embodiment 1, except that the upper curtain 1 and / or the lower curtain 2 include a furnace opening blocking part perpendicular to the material advancing direction, and a side wall abutment part 5 located on the side of the furnace opening blocking part in the width direction.

[0064] Specifically, when higher materials pass through the lower curtain 2, the upper curtain 1 and / or the lower curtain 2 will be pushed away from the conveyor belt and move in the material conveying direction. The upper curtain 1 and / or the lower curtain 2 include a furnace opening blocking part perpendicular to the material moving direction, and a side wall abutment part 5 located on the side of the furnace opening blocking part in the width direction. The side wall abutment part 5 is always in contact with the side wall on the side of the furnace opening blocking part in the width direction, avoiding gaps between the inner side wall of the heating chamber and the upper curtain 1 and / or the lower curtain 2. At this time, the heat transfer on both sides of the flexible heat insulation curtain is less.

[0065] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
