Description

Technical Field

[0001] This utility model relates to the field of kiln technology, and in particular to a kiln system for treating and reusing exhaust gas. Background Technology

[0002] A kiln is a device used for high-temperature material processing, commonly found in industries such as ceramics, metallurgy, and glass. It utilizes heat generated from fuel combustion or electrical energy conversion to heat materials to the required high temperature through conduction, radiation, and convection, achieving processes such as drying, calcination, and melting.

[0003] Kiln systems typically install filters on exhaust gas reuse pipes. These filters effectively remove particulate matter and other impurities from the exhaust gas, preventing blockages or damage to the kiln system. However, in traditional kiln systems, the filters are often fixed inside the pipe with numerous bolts. These filters require cleaning after a period of use, making disassembly and cleaning inconvenient and detrimental to user experience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a kiln system for treating and reusing exhaust gas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A kiln system for treating and reusing exhaust gas includes a kiln body and an electric furnace for treating exhaust gas. The kiln body is provided with a kiln exhaust gas pipe, the other end of which is connected to the electric furnace. The electric furnace is provided with an exhaust pipe and an exhaust gas reuse pipe, the other end of which is connected to the kiln body. A mounting base is fixedly installed on the exhaust gas reuse pipe. The top of the mounting base has a downward-facing installation cavity. Both sides of the installation cavity are connected to the exhaust gas reuse pipe. A detachable mounting component is provided inside the installation cavity, and a filter assembly is fixedly installed on the mounting component.

[0007] In addition, in a preferred structure, the top of the fixing base is fixedly provided with guide posts on both sides of the mounting cavity, and side members are fixedly provided on both sides of the mounting component, with guide cavities adapted to the guide posts on the side members.

[0008] Furthermore, in a preferred configuration, a spring cavity is provided on one side of the mounting component located in the guide cavity, and springs are installed on the inner walls of the spring cavities.

[0009] In addition, a preferred structure is that the other end of each spring is connected to a limiting post, and a limiting cavity is adapted to be formed on the guide post corresponding to the limiting post.

[0010] In addition, a preferred structure is that a connecting rod is fixedly provided on the limiting post, the other end of the connecting rod extends out from the side member, and a handle is fixedly provided on the part of the connecting rod that extends out from the side member.

[0011] Furthermore, in a preferred configuration, all connecting rods pass through the spring, and the diameter of the limiting post is the same as the diameter of the spring cavity.

[0012] The beneficial effects of this utility model are as follows: the waste gas generated in the kiln body can be treated and reused by the waste gas treatment electric furnace; the filter assembly can prevent the kiln body from being blocked by impurities in the waste gas; the filter assembly can be fixed by the matching and locking between the limiting column and the limiting cavity. This method of assembling the filter assembly is relatively simple and convenient for users to disassemble and clean the filter assembly later. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Reference Figure 1-6 A kiln system for treating and reusing exhaust gas includes a kiln body 1 and an electric furnace 12 for exhaust gas treatment. The kiln body 1 is equipped with an exhaust gas pipe 11, the other end of which is connected to the electric furnace 12. The electric furnace 12 is equipped with an exhaust pipe 13 and an exhaust gas reuse pipe 14, the other end of which is connected to the kiln body 1. A mounting base 2 is fixedly installed on the exhaust gas reuse pipe 14. The top of the mounting base 2 has a downward-facing mounting cavity 21, both sides of which communicate with the exhaust gas reuse pipe 14. A detachable mounting component 3 is installed inside the mounting cavity 21, and a filter assembly 31 is fixedly installed on the mounting component 3.

[0022] In this design, guide posts 22 are fixedly mounted upwards on both sides of the top of the mounting base 2, located in the mounting cavity 21. Side members 32 are fixedly mounted on both sides of the mounting component 3, and guide cavities 321 are adapted to fit the guide posts 22 on the side members 32. Through the adaptation between the guide posts 22 and the guide cavities 321, the mounting component 3 can be guided during assembly.

[0023] The mounting component 3 has a spring cavity 322 connected to one side of the guide cavity 321, and springs 33 are installed on the inner walls of the spring cavities 322. A limiting post 34 is connected to the other end of each spring 33, and a limiting cavity 23 is correspondingly provided on the guide post 22 to the limiting post 34. The springs 33 allow the limiting post 34 to be pushed outward from the spring cavity 322.

[0024] The limiting post 34 is fixedly provided with a connecting rod 341, the other end of which extends from the side member 32, and a handle 342 is fixedly provided on the part of the connecting rod 341 that extends from the side member 32. The limiting post 34 can be controlled to move by the connecting rod 341 and the handle 342.

[0025] In this configuration, the connecting rods 341 all pass through the spring 33, and the diameter of the limiting post 34 is the same as the diameter of the spring cavity 322.

[0026] In this embodiment, the waste gas generated inside the kiln body 1 enters the waste gas treatment electric furnace 12 through the kiln waste gas pipe 11. The waste gas treatment electric furnace 12 filters the waste gas, and a portion of the filtered waste gas is discharged through the exhaust pipe 13. The waste gas treatment electric furnace 12 is equipped with a heat exchange component, which facilitates heat exchange with the waste gas. The higher-temperature waste gas after heat exchange is filtered by the waste gas treatment electric furnace 12 and enters the tail gas reuse pipe 14, and then re-enters the kiln body 1 through the tail gas reuse pipe 14, thus utilizing the heat from the waste gas. It is worth noting that this structure and principle are existing technologies, disclosed in existing Chinese patents, and therefore will not be elaborated further.

[0027] Furthermore, by installing a filter assembly 31 inside the exhaust gas reuse pipe 14, the recovered gas can be filtered to prevent the kiln body 1 from being blocked by impurities in the recovered exhaust gas.

[0028] When the user needs to install the filter assembly 31, simply insert the mounting piece 3 into the mounting cavity 21 on the fixing base 2. At this time, the side piece 32 on the mounting piece 3 is adapted to fit on the guide post 22. Then, the user simply pulls the handles 342 on both sides of the side piece 32 outward, thereby pulling the limiting post 34 into the spring cavity 322 through the handles 341 and the connecting rod 341, at which time the spring 33 is compressed. Subsequently, the mounting piece 3 can automatically move downward by gravity. When the mounting piece 3 is fully inserted into the mounting cavity 21, the spring cavity 322 and the limiting cavity 23 are aligned. At this time, the user simply releases the handles 342 on both sides, and the limiting post 34 in the spring cavity 322 will automatically return to its original position by the elastic force of the spring 33. At this time, the limiting post 34 can fit into the limiting cavity 23, thereby realizing the fixed installation of the filter assembly 31 of the mounting piece 3.

[0029] When the user needs to disassemble the filter assembly 31 for cleaning, simply pull the handles 342 on both sides outwards, at which point the limiting post 34 will disengage from the limiting cavity 23. The user can then remove the filter assembly 31 by moving the mounting piece 3 upwards.

[0030] It is worth noting that the mounting part 3 is equipped with a seal, which can improve the sealing performance of the filter assembly 31 after installation.

[0031] In this utility model, the waste gas generated in the kiln body 1 can be treated and reused by the waste gas treatment electric furnace 12. The filter assembly 31 can prevent the kiln body 1 from being blocked by impurities in the recovered waste gas. The filter assembly 31 can be fixed by the adapter locking between the limiting post 34 and the limiting cavity 23. This assembly method of the filter assembly 31 is relatively simple and convenient for users to disassemble and clean the filter assembly 31 later.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
