Description

Technical Field

[0001] This utility model relates to the field of multi-purpose furnace technology, and in particular to a multi-purpose furnace with good sealing performance. Background Technology

[0002] Carburizing and quenching is a heat treatment process in metal processing. Through carburizing and quenching, the surface of the carburized workpiece can obtain a high hardness, thereby further improving the wear resistance of the workpiece. Therefore, a carburizing and quenching multi-purpose furnace is needed for carburizing and quenching. The carburizing and quenching multi-purpose furnace with controlled atmosphere can perform quenching processing on a variety of metal materials.

[0003] Currently, multi-purpose furnaces on the market need to exhaust flue gas when heating workpieces. Traditional multi-purpose furnaces have relatively short exhaust pipes. When the multi-purpose furnace is installed indoors, the exhaust pipe needs to be connected to an external connecting pipe to exhaust the flue gas outdoors. The traditional connection method between the connecting pipe and the exhaust pipe is installed and connected by multiple fixed components. Not only is the installation and connection process cumbersome, but the sealing at the connection is also poor, which can easily cause flue gas leakage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-purpose furnace with good sealing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-purpose stove with good sealing performance includes a stove body, a flue pipe is provided on one side wall of the top of the stove body, a connecting pipe is vertically connected above the flue pipe, and a sealing component is provided at the connection between the flue pipe and the connecting pipe. The sealing assembly includes a sealing block, which is symmetrically and slidably fitted on the exhaust pipe. A sealing cavity is provided on the sealing block, and sliding plates are symmetrically arranged on both sides of the sealing block, which are slidably fitted on the exhaust pipe.

[0006] Furthermore, in a preferred configuration, the exhaust pipe includes a connector for installing a connecting pipe, and a mounting base for installing a sealing component is provided below the connector. The connector includes a connecting disc body, which is used to mate with the connecting pipe within a sealing cavity. Multiple sealing rubber rings are evenly arranged vertically on the outer wall of the connector.

[0007] In addition, a preferred structure is that the mounting base has symmetrical sliding cavities on both sides, each sliding cavity is provided with a sliding rod, the sliding plate is slidably fitted on the sliding rod, and mounting holes are symmetrically provided on the side walls of both sides of the mounting base.

[0008] Furthermore, in a preferred configuration, the sealing assembly includes a spring and a mounting cover plate, with the mounting cover plate symmetrically mounted on the surfaces of the mounting base where mounting holes are provided.

[0009] In addition, a preferred structure is that the spring is sleeved on the slide rod, with one end of the spring abutting against the mounting cover plate and the other end of the spring abutting against the sliding plate.

[0010] In addition, a preferred structure is that each of the sliding plates has a sliding hole at the bottom and a through hole at the top, and a pull ring is provided on the outer surface of the sealing block.

[0011] The beneficial effects of this utility model are as follows: This utility model achieves rapid connection and high-sealing fixation between the exhaust pipe and the connecting pipe through the set sealing components. The symmetrically slidable sealing blocks and their sealing cavities, together with the multiple sealing rubber rings set on the outer wall of the connector, effectively enhance the sealing performance of the connection and prevent smoke leakage. At the same time, the sliding cooperation between the sliding plate and the sliding rod, as well as the elastic restoring effect of the spring, make the installation and disassembly process simpler and faster, without the need for complicated fixing tools.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-6A multi-purpose furnace with good sealing performance includes a furnace body 1. A flue pipe 2 is provided on one side wall of the top of the furnace body 1. A connecting pipe 3 is vertically connected above the flue pipe 2. A sealing component 4 is provided at the connection between the flue pipe 2 and the connecting pipe 3. The sealing component 4 includes a sealing block 41, which is symmetrically and slidably fitted on the flue pipe 2. A sealing cavity 411 is provided on the sealing block 41. Sliding plates 412 are symmetrically arranged on both sides of the sealing block 41 and are slidably fitted on the flue pipe 2. The sealing component 4 is used to improve the sealing performance and at the same time realize the quick connection and fixation between the flue pipe 2 and the connecting pipe 3.

[0016] The exhaust pipe 2 includes a connector 21 for installing the connecting pipe 3. Below the connector 21 is a mounting base 22 for installing the sealing component 4. The connector 21 includes a connecting disc 211, which is used to cooperate with the connecting pipe 3 in the sealing cavity 411. Multiple sealing rubber rings 212 are evenly arranged on the outer wall of the connector 21 in the vertical direction. The sealing rubber rings 212 help to improve the sealing performance at the connection between the connecting pipe 3 and the exhaust pipe 2.

[0017] Furthermore, the mounting base 22 has symmetrical sliding cavities 221 on both sides, and each sliding cavity 221 is provided with a sliding rod 222. The sliding plate 412 is slidably fitted on the sliding rod 222. The mounting base 22 has symmetrical mounting holes 223 on both side walls, and the sliding rod 222 enables the sealing block 41 to slide.

[0018] Meanwhile, the sealing assembly 4 includes a spring 42 and a mounting cover plate 43. The mounting cover plate 43 is symmetrically installed on the surfaces of the mounting base 22 where mounting holes 223 are opened. The spring 42 is sleeved on the slide rod 222. One end of the spring 42 abuts against the mounting cover plate 43, and the other end of the spring 42 abuts against the sliding plate 412. The spring 42 realizes the reset of the sliding plate 412.

[0019] In addition, the bottom of the sliding plate 412 is provided with a sliding hole 4121, the top of the sliding plate 412 is provided with a through hole 4122, and a pull ring 413 is provided on the outer surface of the sealing block 41. The pull ring 413 makes it easy for the operator to pull open the sealing blocks 41 on both sides.

[0020] In this embodiment, when the furnace body 1 is working, in order to exhaust the flue gas outdoors, an external connecting pipe 3 needs to be connected to the flue pipe 2. By vertically inserting the connecting pipe 3 into the flue pipe 2, the sealing rubber ring 212 contacts the inner wall of the connecting pipe 3, thereby improving its sealing performance. During installation, the sealing component 4 is pulled open, and the sealing block 41 is separated by the pull ring 413. The sliding plate 412 slides on the sliding rod 222, and the sliding plate 412 compresses the spring 42. At this time, the connecting pipe 3 can be quickly installed. The bottom connector of the connecting pipe 3 is attached to the connecting plate 211. Then, the pull ring 413 is released, and the spring 42 releases its elastic potential energy, thereby resetting the sealing blocks 41 on both sides, so that the connection between the connector 21 and the connecting pipe 3 is locked into the sealing cavity 411, thereby fixing the flue pipe 2 and the connecting pipe 3 so that they cannot be separated. Furthermore, if the spring 42 loosens later, a fixing component can be added at the through hole 4122 to improve its firmness.

[0021] In this invention, the sealing component 4 enables a quick connection and high-sealing fixation between the exhaust pipe 2 and the connecting pipe 3. The symmetrically sliding sealing block 41 and its sealing cavity 411, together with the multiple sealing rubber rings 212 on the outer wall of the connector 21, effectively enhance the sealing performance of the connection and prevent smoke leakage. At the same time, the sliding cooperation between the sliding plate 412 and the sliding rod 222, as well as the elastic reset effect of the spring 42, make the installation and disassembly process simpler and faster, without the need for complicated fixing tools.
