Description

Technical Field

[0001] This application relates to the field of heat treatment technology, and more specifically, to a heat treatment apparatus for silicon steel sheets. Background Technology

[0002] In the prior art, for example, a novel silicon steel sheet heat treatment equipment disclosed in CN205687974U includes a flange housing, a controller, an exhaust device, a bracket, a coupling, a temperature and humidity sensor, a material box, a roller, a transmission device, a radiant tube, and a steam pipe. The controller is mounted on the top of the flange housing via the bracket; the exhaust device is located on the upper side of the flange housing; the bracket is connected to both sides of the flange housing via the coupling; the temperature and humidity sensor is located inside the flange housing; the material box is placed on the upper part of the roller; and the transmission device is connected to the outside of the roller.

[0003] This solution utilizes exhaust devices, temperature and humidity sensors, and controllers to facilitate observation of the production process, control water vapor emissions conveniently and easily, ensure stable product quality, achieve a high degree of automation, and reduce labor costs.

[0004] However, in this design, both the exhaust device and the observation window are located on the top of the flange housing. Even if the observation window does not produce condensation due to the high temperature, the water vapor permeating the flange housing will affect the worker's vision when looking at the workpiece through the observation window, making it difficult for the worker to observe the workpiece. At the same time, since the exhaust device and the observation window are located on the same side, the airflow from the exhaust device can easily cause injury to the worker who is observing.

To this end, this application proposes a silicon steel sheet heat treatment apparatus, which aims to improve upon the problems in an existing silicon steel sheet heat treatment apparatus where the diffused water vapor obstructs the worker's vision, and the exhaust airflow easily causes harm to the worker.

[0006] This application discloses a heat treatment apparatus for silicon steel sheets, including a heat treatment chamber. The heat treatment chamber is equipped with a control device for controlling the operation of various components inside the chamber.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figures 1-4 As shown, a silicon steel sheet heat treatment apparatus according to an embodiment of this application includes a heat treatment chamber 1. The heat treatment chamber 1 is equipped with a control device for controlling the operation of various components inside the heat treatment chamber 1. Specifically, the structure and working principle of the control device and the control system therein are well known in the art and will not be described in detail here.

[0024] The heat treatment chamber 1 has an exhaust port 12 on its top and a window 13 on its front. Understandably, with this design, when the hot airflow inside the heat treatment chamber 1 is discharged from the exhaust port 12, it will not interfere with the front of the heat treatment chamber 1. That is, when the staff stands on the front of the heat treatment chamber 1 and observes through the window 13, they will not be harmed by the hot airflow discharged from the exhaust port 12.

[0025] like Figure 2 As shown, the heat treatment chamber 1 is equipped with a heat treatment assembly 2 and a material conveying assembly 3. The heat treatment assembly 2 includes multiple radiant tubes 21 and multiple steam tubes 22. It should be noted that the radiant tubes 21 are used to provide heat, and the steam tubes 22 are used to provide steam.

[0026] An air supply assembly 4 is provided at the bottom of the heat treatment chamber 1. The air supply assembly 4 includes a fan 42 and a flow equalizer 43. The fan 42 is evenly distributed at the bottom of the heat treatment chamber 1. The flow equalizer 43 corresponds to the fan 42 one by one. The flow equalizer 43 is rotatably connected to the heat treatment chamber 1.

[0027] It should be noted that the specific connection method of fan 42 to the power supply is well known in the art and will not be described in detail here.

[0028] Furthermore, the heat treatment box 1 is symmetrically provided with loading and unloading ports 11 on both sides, and the conveying assembly 3 is adapted to the loading and unloading ports 11 so that the conveying assembly 3 can complete the conveying action of the silicon steel sheet to be treated in the heat treatment box 1.

[0029] Multiple radiant tubes 21 are evenly arranged inside the heat treatment chamber 1 and located on the bottom side of the conveying assembly 3, with the multiple radiant tubes 21 and the conveying assembly 3 arranged in parallel. Multiple steam pipes 22 are evenly arranged inside the heat treatment chamber 1 and located on the top side of the conveying assembly 3, with the multiple steam pipes 22 and the conveying assembly 3 arranged in parallel and connected to an external steam supply device. It can be understood that the radiant tubes 21 can deliver heat to the workpiece to be processed on the conveying assembly 3 as evenly as possible, and the steam pipes 22 can deliver steam to the workpiece as much as possible. It should be further noted that the steam pipes 22 have evenly distributed vent holes on the side facing the workpiece to facilitate the discharge of steam.

[0030] Furthermore, the material conveying assembly 3 includes a conveying component 31 and a material box 32. The two ends of the conveying component 31 correspond to the symmetrically arranged upper and lower material ports 11, and the material box 32 is placed on the conveying component 31 and carries the silicon steel sheet workpiece.

[0031] It should be noted that, in the specific embodiments of this application, the conveyor 31 is preferably a roller conveyor, and the material box 32 is preferably a hollow frame structure, so that the radiation tube 21 below it can transfer heat to the workpiece inside the material box 32, and at the same time, it is convenient for the staff to observe the workpiece inside the material box 32 from the window 13.

[0032] Furthermore, the air supply assembly 4 also includes a filter box 41 located at the bottom of the heat treatment chamber 1. The air inlet of the filter box 41 is connected to the outside of the heat treatment chamber 1, and the air outlet of the filter box 41 faces the fan 42. The filter box 41 contains activated carbon and other related filter materials to purify the airflow entering from the outside.

[0033] It should be noted that, in the specific embodiments of this application, multiple sensors are installed inside the heat treatment chamber 1 to monitor the temperature and humidity changes inside the heat treatment chamber 1 in real time. In conjunction with the rotation speed of the fan 42, the amount of airflow discharged through the exhaust port 12 is used to control the temperature and humidity inside the heat treatment chamber 1.

[0034] Furthermore, the fan 42 is evenly embedded in the mounting plate 421, which is fixed to the inside of the heat treatment chamber 1.

[0035] Furthermore, one end of each of the multiple flow equalizers 43 is rotatably connected to the baffle 431, and the other end of each of the multiple flow equalizers 43 is rotatably connected to the inner wall of the heat treatment chamber 1. The other ends of the multiple flow equalizers 43 are also connected to the first transmission member 44 and the second transmission member 45.

[0036] Furthermore, the two ends of the first transmission member 44 are keyed to two adjacent flow equalizers 43, and the two ends of the second transmission member 45 are keyed to two adjacent flow equalizers 43, wherein one end of the first transmission member 44 and one end of the second transmission member 45 are at the same position, and one end of the first transmission member 44 is keyed to the output shaft of the motor 441.

[0037] It should be noted that, in the specific embodiments of this application, the first transmission component 44 and the second transmission component 45 are preferably sprockets and chains to improve heat resistance.

[0038] like Figure 3 and Figure 4 As shown, it can be understood that the motor 441 can synchronously drive the first transmission component 44 and the second transmission component 45 to rotate synchronously in the same direction. It should be noted that the motor 441 has forward and reverse rotation functions. In this way, it can drive multiple flow equalizers 43 to rotate around their own rotation connection positions as axes to a certain extent. It can be further understood that the rotation of the flow equalizer 43 will cause the airflow blown by the fan 42 below to be continuously disturbed by the flow equalizer 43. This will make the airflow carrying the heat generated by the radiant tube 21 be transferred to the workpiece as evenly as possible, avoiding uneven heat on the workpiece. It can also be understood that the steam delivered to the workpiece by the steam pipe 22 can control the temperature of the workpiece to a certain extent, preventing the heat on the workpiece from exceeding the predetermined range.

[0039] It should be noted that the specific models and specifications of the heat treatment box 1, radiant tube 21, steam pipe 22, conveyor 31, fan 42, first transmission component 44, second transmission component 45 and motor 441 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
