Description

Technical Field

[0001] This utility model relates to the field of spray welding heating technology, and in particular to a heating box for a spray welding heating furnace. Background Technology

[0002] Currently, waste incinerator grates are typically made of high-chromium cast iron, and their wear and corrosion resistance is improved through spray welding. Before spray welding, the grates need to be heated. However, in existing spray welding furnaces, when multiple grates are heated simultaneously, uneven heating and significant temperature differences can easily occur, affecting the subsequent spray welding quality. Therefore, a spray welding furnace heating box that can improve the heating uniformity of the grates is needed. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a heating box for a spray welding furnace, which aims to improve the problem in the prior art where the heating box heats multiple grates unevenly, resulting in large temperature differences and affecting the subsequent spray welding effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a heating box for a spray welding furnace, comprising a frame, a bottom plate fixedly connected to the bottom surface of the frame, a load-bearing bar fixedly connected to the top of the bottom plate, a side wall provided on the outer wall of the frame, and multiple grates provided on the top of the load-bearing bar.

[0005] As a further description of the above technical solution:

[0006] The outer walls of the base plate and side panels are both coated with infrared radiation ceramic coating.

[0007] As a further description of the above technical solution:

[0008] Multiple reinforcing ribs are fixedly connected to the top four corners of the frame, and these reinforcing ribs are used to enhance the structural strength.

[0009] As a further description of the above technical solution:

[0010] The top surface of the reinforcing rib has a lifting hole, which facilitates the hoisting and transportation of the frame.

[0011] As a further description of the above technical solution:

[0012] The bottom of the grate is provided with multiple fixing plates.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the fixed plate is provided with a second lifting hole, which is used to lift and transfer the grate.

[0015] As a further description of the above technical solution:

[0016] A structural column is fixedly connected to the middle of the frame, and the structural column is used to increase the structural strength of the frame.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, the outer side of the base plate and side wall has an infrared radiation ceramic coating to block the radiant heat generated by the quartz heating tube from directly baking the grate inside the frame. This allows the grate inside the frame to heat up evenly, avoiding large temperature differences between the grates after heating, which would affect the spray welding effect. This makes it convenient to place the grate inside the heating furnace for heating, and ensures that the grate heats up evenly, thus improving the efficiency of grate spray welding.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model is provided: a heating box for a spray welding heating furnace, including a frame 1, a bottom plate 4 fixedly connected to the bottom surface of the frame 1, a load-bearing rod 2 fixedly connected to the top of the bottom plate 4, a side wall 5 provided on the outer wall of the frame 1, and a plurality of grates 3 provided on the top of the load-bearing rod 2.

[0026] Specifically, a heating box for a heating furnace specifically designed for spray welding mainly includes a frame 1. A flat base plate 4 is fixedly installed on the bottom surface of the frame 1 through a sturdy connection. Multiple load-bearing bars 2 are fixedly installed on the top of the base plate 4. The load-bearing bars 2 are mainly used to support the weight above. The outer wall of the frame 1 is provided with side panels 5 to enhance the stability and sealing of the overall structure. Multiple grates 3 are evenly distributed on the top of the load-bearing bars 2.

[0027] Please see the appendix Figure 1 - Appendix Figure 3 The outer walls of the base plate 4 and the side wall 5 are all provided with infrared radiation ceramic coating. Multiple reinforcing ribs 6 are fixedly connected to the top four corners of the frame 1. The reinforcing ribs 6 are used to strengthen the structural strength. The top surface of the reinforcing ribs 6 is provided with lifting holes 7, which facilitates the hoisting and transportation of the frame 1.

[0028] Specifically, the outer surfaces of the base plate 4 and the side walls 5 are uniformly coated with a ceramic coating with infrared radiation properties to block the radiant heat generated by the quartz heating tube from directly baking the grate 3 inside the frame 1. Multiple reinforcing ribs 6 are firmly fixed to the four corners of the top of the frame 1 to enhance the overall structural strength, thereby improving the load-bearing capacity and stability of the frame 1. The top surface of the reinforcing ribs 6 is provided with specially designed lifting holes 7. The lifting holes 7 facilitate the operation of the frame 1 during hoisting and transportation, ensuring the convenience and safety of the hoisting process.

[0029] Please see the appendix Figure 1 - Appendix Figure 3 The bottom of the grate 3 is provided with multiple fixing plates 8. The outer wall of the fixing plate 8 is provided with lifting holes 9. The lifting holes 9 are used to lift and transfer the grate 3. The middle part of the frame 1 is fixedly connected with a structural column 10. The structural column 10 is used to increase the structural strength of the frame 1.

[0030] Specifically, multiple fixing plates 8 are set at the bottom of the grate 3. The outer wall of the fixing plates 8 has special lifting holes 9. The main function of these lifting holes 9 is to facilitate the lifting and transfer of the grate 3 when needed, ensuring the smooth progress of the whole process. Multiple structural columns 10 are fixedly connected in the middle of the frame 1, which can enhance the overall structural strength of the frame 1, so that it can remain stable when subjected to various external forces, ensuring the safety and durability of the entire device.

[0031] Working principle: The outer sides of the base plate 4 and the side wall 5 are coated with infrared radiation ceramic coating to block the radiant heat generated by the quartz heating tube from directly baking the grate 3 inside the frame 1. This allows the grate 3 inside the frame 1 to heat up evenly, avoiding large temperature differences between the grates 3 after heating, which would affect the spray welding effect. This makes it convenient to place the grate 3 in the heating furnace for heating, and ensures that the grate 3 heats up evenly, thus improving the efficiency of grate spray welding.
