Description

Technical Field

[0001] This application relates to the technical field of drying objects, and in particular to a drying oven. Background Technology

[0002] An oven is a piece of equipment used in industry to dry products.

[0003] Currently, reference Figure 1 An oven includes a body 1, within which a heating chamber 11 is formed. An inlet 13 and an outlet communicating with the heating chamber 11 are respectively opened at both ends of the body 1. Two hinged doors 14 are connected to both ends of the body 1, covering the inlet 13 and the outlet respectively. A movement hole 12 communicating with the heating chamber 11 is opened at the top of the body 1. A chain is provided at the top of the body 1, and a movement rod 5 is fixed to the chain. A hook is fixedly connected to the movement rod 5. The object to be dried is hung on the hook of the movement rod 5, and then the chain drives the movement rod 5 to move. The movement rod 5 moves the object to be dried, allowing it to enter the heating chamber 11. The movement rod 5 moves within the movement hole 12, and the object moves within the heating chamber 11, thereby achieving the drying of the object.

[0004] When the moving rod 5 moves the object within the moving hole 12, causing the object to move within the heating chamber 11, the heat within the heating chamber 11 will dissipate through the moving hole 12. Utility Model Content

[0005] In order to reduce the heat loss from the heating chamber, this application provides an oven.

[0006] This application provides an oven that adopts the following technical solution:

[0007] An oven includes a housing with a heating chamber formed therein. A movement hole, connected to the heating chamber, is provided at the upper end of the housing for a moving rod to pass through. The oven also includes multiple sealing mechanisms, each comprising two arc-shaped sealing blocks. These two arc-shaped sealing blocks are respectively disposed on the housing on both sides of the movement hole and abut against each other. Two adjacent sealing mechanisms located on the same side of the movement hole have their arc-shaped sealing blocks abutting against each other. The moving rod passes sequentially through the multiple sealing mechanisms on the movement hole. When the moving rod is inside the movement hole, two arc-shaped sealing blocks in one of the sealing mechanisms abut against the moving rod, while two arc-shaped sealing blocks in the other sealing mechanisms remain in abutting state.

[0008] By adopting the above technical solution, when the moving rod is not moving within the moving hole, the two arc-shaped sealing blocks in all sealing mechanisms abut against each other, and the two arc-shaped sealing blocks in two adjacent sealing mechanisms located on the same side of the moving hole also abut against each other, thus reducing the phenomenon of heat dissipation from the heating cavity; moreover, when the moving rod is moving within the moving hole, the two arc-shaped sealing blocks in one sealing mechanism abut against the moving rod, while the two arc-shaped sealing blocks in the other sealing mechanisms remain in abutting state, which also reduces the phenomenon of heat dissipation from the heating cavity; therefore, the sealing mechanism provided in this application can reduce the dissipation of heat from the heating cavity.

[0009] Optionally, the arc-shaped sealing block includes an arc-shaped adjusting plate and a sealing plate. The arc-shaped adjusting plate is connected to the housing, and the sealing plate is disposed on the arc-shaped adjusting plate. In the same sealing mechanism, the ends of two sealing plates away from the arc-shaped adjusting plate abut against each other. Furthermore, two arc-shaped adjusting plates of two adjacent sealing mechanisms located on the same side of the moving hole abut against each other, and two sealing plates of two adjacent sealing mechanisms located on the same side of the moving hole abut against each other.

[0010] By adopting the above technical solution, when the moving rod moves in the moving hole, the moving rod will cause the arc-shaped adjusting plate to move and undergo a certain deformation. The deformed arc-shaped adjusting plate can drive the sealing plate to move, so that the two sealing plates in the same sealing mechanism abut against the moving rod.

[0011] Optionally, the arc-shaped adjustment plate is inclinedly disposed on the housing, and the arc-shaped adjustment plate is inclinedly disposed along the movement direction of the moving rod; when the moving rod moves to the point where one of the sealing mechanisms is close to the other sealing mechanism, a part of the moving rod is located between the two sealing plates in the first sealing mechanism, and the other part is located between the two arc-shaped adjustment plates in the next sealing mechanism in the movement direction.

[0012] By adopting the above technical solution, when the moving rod moves in the moving hole, part of the moving rod will be located between the two sealing plates of a sealing mechanism, and part of the moving rod will be located between the two arc-shaped adjustment plates of the next sealing mechanism in the direction of movement. In this way, when the moving rod moves, it will adjust the position between the two arc-shaped adjustment plates, so that the arc-shaped adjustment plates in the next sealing mechanism in the direction of movement will drive the two sealing plates to move, so that the moving rod can enter between the two sealing plates of the next sealing mechanism in the direction of movement.

[0013] Optionally, at least one of the arc-shaped adjusting plates in the same sealing mechanism is provided with a guide groove; the moving rod abuts against the guide groove and enters between the two arc-shaped adjusting plates through the guide groove.

[0014] By adopting the above technical solution, the guide groove can facilitate the movement rod to enter between the two arc-shaped adjustment plates in the next direction of movement, so that the movement rod can enter the end of the two arc-shaped adjustment plates near the sealing plate, and thus enter between the two sealing plates.

[0015] Optionally, the moving rod is provided with an adjustment support block, and the two arc-shaped adjustment plates in the same sealing mechanism can abut against the adjustment support block on their adjacent sides.

[0016] By adopting the above technical solution, when the moving rod moves, the adjusting support block on the moving rod will first abut against the two arc-shaped adjusting plates and push the arc-shaped adjusting plates open, so that the arc-shaped adjusting plates can enter between the two sealing plates.

[0017] Optionally, the adjusting support block includes a connecting block and a guide block. The connecting block is disposed on the moving rod, and the guide block is disposed on the connecting block. The cross-sectional area of ​​the guide block at the end away from the connecting block is smaller than the cross-sectional area at the end closer to the connecting block.

[0018] By adopting the above technical solution, the end of the guide block away from the connecting block will first enter between the two arc-shaped adjustment plates of the sealing mechanism in the next direction of movement. Then, under the guidance of the guide block, the connecting block will enter between the two arc-shaped adjustment plates, and the two arc-shaped adjustment plates will drive the sealing plate to move, so that the moving rod enters between the two sealing plates.

[0019] Optionally, the arc-shaped sealing block is made of a resilient steel plate.

[0020] By adopting the above technical solution, the arc-shaped sealing block made of elastic steel plate can easily deform when the moving rod moves, which facilitates the movement of the moving rod in the moving hole, and has a relatively long service life.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The sealing mechanism provided in this application can reduce the loss of heat from the heating chamber;

[0023] 2. The arc-shaped sealing block made of elastic steel plate can easily deform when the moving rod moves, which facilitates the movement of the moving rod in the moving hole and has a relatively long service life. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0030] This application discloses an oven. Example

[0031] refer to Figure 2 An oven includes a body 1, within which a heating chamber 11 is formed. An inlet 13 and an outlet communicating with the heating chamber 11 are respectively opened at both ends of the body 1. Two hinged doors 14 are connected to both ends of the body 1, covering the inlet 13 and the outlet respectively. A movement hole 12 communicating with the heating chamber 1 is opened at the top of the body 1. A chain is provided at the top of the body 1, and a movement rod 5 is fixed to the chain. A hook is fixedly connected to the movement rod 5. Multiple sealing mechanisms 2 for sealing the movement hole 12 are provided on the body 1.

[0032] refer to Figure 2 and Figure 3 Each sealing mechanism 2 includes two arc-shaped sealing blocks 21 fixed on the housing 1. The two arc-shaped sealing blocks 21 are located on both sides of the motion hole 12, and each arc-shaped sealing block 21 is made of elastic steel plate.

[0033] refer to Figure 2 and Figure 3 Each arc-shaped sealing block 21 includes an arc-shaped adjusting plate 211 fixedly connected to the housing 1. The arc-shaped adjusting plates 211 are inclined along the direction of movement of the moving rod 5. A sealing plate 212 is integrally provided on the end of the arc-shaped adjusting plate 211 away from the end connected to the housing 1. The ends of the two sealing plates 212 in the same sealing mechanism 2 away from the arc-shaped adjusting plate 211 abut against each other. The two arc-shaped adjusting plates 211 of the two adjacent sealing mechanisms 2 located on the same side of the moving hole 12 abut against each other.

[0034] Each arc-shaped adjustment plate 211 is provided with a guide groove 3, and the guide groove 3 is located on the entry side of the arc-shaped adjustment plate 211. That is, the moving rod 5 first touches the guide groove 3, and then enters between the two arc-shaped adjustment plates 211 in the same sealing mechanism 2.

[0035] The implementation principle of Embodiment 1 of this application is as follows: When the moving rod 5 moves into the moving hole 12 of the housing 1, the moving rod 5 is first located between the two arc-shaped adjusting plates 211 in the same sealing mechanism 2. Then, the moving rod 5 abuts against the guide grooves 3 on the two arc-shaped adjusting plates 211 in the same sealing mechanism 2. At this time, the moving rod 5 will cause the two arc-shaped adjusting plates 211 to move in opposite directions. The two arc-shaped adjusting plates 211 will then drive the two sealing plates 212 to move in opposite directions, and the two sealing plates 212 will abut against the moving rod 5. When the moving rod 5 moves to a sealing mechanism 2 and approaches the next sealing mechanism 2 in the direction of movement, part of the moving rod 5 is still located between the two sealing plates 212 of this sealing mechanism 2, and part of the moving rod 5 is located between the two arc-shaped adjusting plates 211 of the next sealing mechanism 2 in the direction of movement. Example

[0036] refer to Figure 4 The difference from Embodiment 1 is that the motion rod 5 is provided with an adjustment support block 4. The adjustment support block 4 includes a connecting block 41 fixedly connected to the motion rod 5. A guide block 42 is fixedly connected to the connecting block 41. The cross-sectional area of ​​the guide block 42 at the end away from the connecting block 41 is smaller than the cross-sectional area at the end close to the connecting block 41.

[0037] The principle of Embodiment 2 of this application is as follows: when a part of the moving rod 5 is still located between the two sealing plates 212 of a sealing mechanism 2, and a part of the moving rod 5 is located between the two arc-shaped adjustment plates 211 of an adjacent sealing mechanism 2, the guide block 42 will first abut against the guide groove 3 on the arc-shaped adjustment plate 211. When the moving rod 5 continues to move, the guide block 42 will open the two arc-shaped adjustment plates 211, so that the moving rod 5 can move between the two sealing plates 212.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
