Description

Technical Field

[0002] High-pressure sintering furnaces are mainly used for the sintering of powder metallurgy products, metal injection molding products, stainless steel bases, cemented carbides, superalloys, high-density alloys, ceramic materials, magnetic materials, NdFeB, etc. In order to connect the high-pressure gas source, the high-pressure sintering furnace has a high-pressure integrated component for connecting the high-pressure gas source and the furnace body. The high-pressure integrated component is a valve component, including a pressure gauge and a manual valve for controlling the connection or cutoff of the high-pressure gas source and the furnace body. Among them, the high-pressure integrated component is used in a high-pressure environment for a long time. Therefore, the sealing ring of the high-pressure integrated component is prone to aging risks, which may cause the high-pressure integrated component to leak and explode.

[0003] However, the high-pressure integrated components of existing high-pressure sintering furnaces are generally exposed outside the furnace body and lack a protective structure. Once the high-pressure integrated components leak and explode, the fragments of the exploded high-pressure integrated components can easily injure surrounding operators, posing a major safety hazard.

[0022] Compared with the prior art, the protective device of a sintering furnace provided by the utility model has the following features:

[0023] Beneficial effects:

[0024] 1. The top of the protection box and one side adjacent to the furnace body are open, which can facilitate the pipeline of the high-pressure integrated component to extend out of the protection box and connect to the high-pressure gas source and the furnace body respectively. Therefore, if the high-pressure integrated component leaks and explodes, the exploded fragments can only splash out from the top of the protection box and the side adjacent to the furnace body. Since the operators around the sintering furnace cannot stand between the furnace body and the side adjacent to the furnace body of the protection box, the top of the protection box is not lower than the top of the furnace body, while the top of the furnace body of the existing sintering furnace is higher than most operators.

[0025] Moreover, the transparent protective plate can close or open the operating window of the protective box. When the transparent protective plate closes the operating window, it can effectively prevent the fragments of the exploded high-pressure integrated component from splashing out from the operating window and injuring the operator. However, since the material of the transparent protective plate is transparent, it does not affect the operator's observation of the value of the pressure gauge through the transparent protective plate. When the transparent protective plate opens the operating window, it can also facilitate the operator to operate the manual valve of the high-pressure integrated component.

[0026] In summary, the protective device for the sintering furnace provided by the utility model does not affect the normal use of the high-voltage integrated components by the operator, but can also protect the operator from being easily injured by the fragments of the exploded high-voltage integrated components, thereby effectively improving the safety of the use of the high-voltage integrated components.

[0027] 2. The base can support the protection box, improve the structural strength of the protection box, thereby improving the protection effect of the protection box, so as to further improve the safety of the use of high-voltage integrated components. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The utility model provides a protective device for a sintering furnace, which is used to solve the problem of how to improve the use safety of a high-voltage integrated component 42 without affecting the use of the high-voltage integrated component 42.

[0040] See also Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional diagram of the protective device of the sintering furnace in the embodiment, Figure 2 for Figure 1 In the enlarged schematic diagram at A, the protective device of the sintering furnace includes a base 1, a protective box 2 and a transparent protective plate 3.

[0041] The sintering furnace 4 includes a furnace body 41 and a high-pressure integrated component 42 . The high-pressure integrated component 42 includes a pressure gauge 421 and a manual valve 422 .

[0042] The base 1 is mounted on the furnace body 41 by welding or screwing.

[0043] The protection box 2 is installed on the base 1 by welding or screwing, and the protection box 2 covers the outside of the high-voltage integrated component 42. One side of the protection box 2 is adjacent to the furnace body 41. The top of the protection box 2 is not lower than the top of the furnace body 41, and the top of the protection box 2 and the side adjacent to the furnace body 41 are both open. The protection box 2 has an operation window 221, and the operation window 221 is opposite to the position of the pressure gauge 421 and the manual valve 422.

[0044] The transparent protection plate 3 is movably mounted at the operation window 221 of the protection box 2 and is used to control the opening and closing of the operation window 221 .

[0045] The top of the protective box 2 and the side adjacent to the furnace body 41 of the protective device of the above technical solution are open, which can facilitate the pipeline of the high-pressure integrated component 42 to extend out of the protective box 2 and be connected to the high-pressure gas source 5 and the furnace body 41 respectively. Therefore, if the high-pressure integrated component 42 leaks and explodes, the exploded fragments can only be splashed out from the top of the protective box 2 and the side adjacent to the furnace body 41; because the operators around the sintering furnace cannot stand between the furnace body 41 and the side of the protective box 2 adjacent to the furnace body 41, the top height of the protective box 2 is not lower than the top of the furnace body 41, and the top of the furnace body 41 of the existing sintering furnace is higher than most operators. Therefore, even if the exploded fragments of the high-pressure integrated component 42 splash out from the top of the protective box 2 and the side adjacent to the furnace body 41, it is not easy to injure the surrounding operators.

[0046] Moreover, the transparent protective plate 3 of the protective device can close or open the operating window 221 of the protective box 2. When the transparent protective plate 3 closes the operating window 221, it can effectively prevent the fragments of the exploded high-pressure integrated component 42 from splashing out from the operating window 221 and injuring the operator. However, since the material of the transparent protective plate 3 is transparent, it does not affect the operator's observation of the value of the pressure gauge 421 through the transparent protective plate 3. When the transparent protective plate 3 opens the operating window 221, it can also facilitate the operator to operate the manual valve 422 of the high-pressure integrated component 42.

[0047] In summary, the protective device of the sintering furnace does not affect the normal use of the high-voltage integrated component 42 by the operator, and can also protect the operator from being easily injured by the fragments of the exploded high-voltage integrated component 42, thereby effectively improving the safety of the use of the high-voltage integrated component 42.

[0048] The base 1 can support the protection box 2, improve the structural strength of the protection box 2, and thus improve the protection effect of the protection box 2, so as to further improve the safety of the high-voltage integrated assembly 42. The base 1 can be installed on the supporting foot of the furnace body 41, rather than on the circumferential surface of the furnace body 41, which is more convenient for installation. If the base 1 is installed on the supporting foot of the furnace body 41, the height of the base 1 needs to be designed to be higher to ensure that the top height of the protection box 2 can not be lower than the top of the furnace body 41.

[0049] The above-mentioned transparent protective plate 3 can be made of transparent materials, such as tempered glass. Tempered glass has high clarity and high structural strength. It will not affect the operator's observation of the value of the pressure gauge 421, and can also resist the fragments of the high-pressure integrated component 42, and is not easily broken and damaged by the fragments of the high-pressure integrated component 42.

[0050] See also Figure 1 and Figure 4As shown, Figure 4 The exploded diagram of the base, protective box and transparent protective plate in the embodiment, the protective device of the sintering furnace also includes at least one upper baffle 6, each upper baffle 6 is connected to the top of the protective box 2 by screwing or welding, and is integrally connected or welded to each other to form a clearance opening 7, the clearance opening 7 is connected to the top of the protective box 2, and the diameter of the clearance opening 7 gradually increases from the top of the protective box 2 upward. In this way, the upper baffle 6 can extend the height of the protective box 2, even if the fragments of the high-voltage integrated component 42 are splashed out from the top of the protective box 2, the upper baffle 6 can also block most of the fragments back into the protective box 2, further protecting the operator from being easily injured by the fragments of the high-voltage integrated component 42, and improving the safety of the use of the high-voltage integrated component 42.

[0051] See also Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment of the protective box 2, the protective box 2 also includes a bottom plate 21, a side plate 22 and a front cover plate 23. The bottom plate 21 is connected to the base 1 by welding or screwing. There are two side plates 22. The bottom of the side plate 22 is connected to the bottom plate 21 by welding or screwing. The operation window 221 is opened on the side plate 22 near the pressure gauge 421 and the manual valve 422. The transparent protective plate 3 is slidably installed on the side plate 22. The left and right sides of the front cover plate 23 are detachably connected to the same side of the two side plates 22. In this way, the protective box 2 is composed of a bottom plate 21, side plates 22 and a front cover plate 23 to form a box structure with an open top and a rear side, wherein the side plates 22 can prevent the fragments of the exploded high-voltage integrated component 42 from injuring the operator standing on the side of the protective box 2, and the front cover plate 23 can correspondingly prevent the fragments of the exploded high-voltage integrated component 42 from injuring the operator standing in front of the protective box 2. It can be seen that the protective box 2 can protect the operators around the high-voltage integrated component 42 from being injured by fragments only through the front cover plate 23 and the two side plates 22, thereby effectively improving the safety of the use of the high-voltage integrated component 42.

[0052] In this embodiment, the above-mentioned upper baffle plate 6, bottom plate 21, side plate 22 and front cover plate 23 can all be made of 5mm iron plate or 5mm aluminum alloy plate in one piece, ensuring that the structural strength of the upper baffle plate 6 and the protective box 2 can withstand the impact of fragments exploded from the high-voltage integrated component 42, and are not easily damaged or deformed by the impact of fragments.

[0053] See also Figure 2 and Figure 4As shown, in one embodiment of the protection box 2, the protection box 2 further includes at least one connecting plate 24, the connecting plate 24 is distributed in parallel with the front cover plate 23, and the connecting plate 24 is connected to the side of the side plate 22 away from the front cover plate 23. In this way, the connecting plate 24 can connect the rear sides of the two side plates 22, and the structural strength of the protection box 2 is improved without affecting the connection between the high-voltage integrated component 42 and the furnace body 41, thereby improving the protection effect of the protection box 2, and further improving the use safety of the high-voltage integrated component 42.

[0054] See also Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of the protective box 2, the front and rear side edges and the bottom edge of the side panel 22 are bent inward to form ear plates 25. The protective box 2 also includes two turning plates 26. The turning plates 26 are located on the outside of the front cover plate 23 and the side panel 22. The turning plates 26 include a first plate portion 261 and a second plate portion 262 vertically connected as one body. The first plate portion 261 is connected to the outside of the side panel 22 by welding or screwing. A plug-in channel 27 is formed between the second plate portion 262 and the ear plate 25 on the front side of the side panel 22. The plug-in channel 27 is used for sliding insertion of one side of the front cover plate 23. The front cover plate 23 is also connected to the upper baffle 6 by welding or screwing. It can be seen that the front cover 23 and the side plate 22 are detachably connected via the turning plate 26. When the protective device is in use, force is applied to make the two sides of the front cover 23 simultaneously insert into or slide out of the two plug-in channels 27, so as to close or open the protective box 2. The operation is simple and convenient, which is conducive to the subsequent maintenance of the high-voltage integrated component 42 located in the protective box 2, and the upper baffle 6 can be slid into or removed from the top of the protective box 2 together with the front cover 23, thereby improving the disassembly and assembly efficiency so that the high-voltage integrated component 42 can be quickly maintained.

[0056] See also Figure 1 As shown, based on the above embodiment, a handle 231 is welded or screwed on the outer surface of the front cover plate 23. In this way, the handle 231 can facilitate the operator to apply force to slide the front cover plate 23 up and down to open or close the protection box 2.

[0057] See also Figure 1 and Figure 4As shown, in this embodiment, there are two front cover plates 23, which are stacked up and down. When in use, the two front cover plates 23 can be inserted into or slid out of the two plug-in channels 27 in sequence to completely close or open the protection box 2, or only one front cover plate 23 can be inserted into or slid out of the two plug-in channels 27, and the other front cover plate 23 is not inserted into or slid out of the two plug-in channels 27, so as to partially close or open the protection box 2, so as to partially maintain the high-voltage integrated component 42. There are two handles 231 on each front cover plate 23, which is convenient for the staff to operate with both hands.

[0058] See also Figure 2 and Figure 4 As shown, in one connection mode between the transparent protective plate 3 and the side plate 22, at least two limit blocks 28 are welded or screwed on the outer surface of the side plate 22, and a sliding channel 29 is formed between the limit blocks 28. The sliding channel 29 is used for sliding connection with the transparent protective plate 3, and the operation window 221 is located in the sliding channel 29. In this way, the transparent protective plate 3 and the side plate 22 are slidably connected through the sliding channel 29. The structure of the sliding connection is simple and the cost is low. The transparent protective plate 3 can slide to control the opening and closing of the operation window 221, and the operation is simple and quick.

[0059] See also Figure 2 and Figure 4 As shown, in one embodiment of the limit block 28, the limit block 28 includes a first limit portion 281 and a second limit portion 282 that are integrally connected, and the first limit portion 281 and the second limit portion 282 are perpendicular to each other so that the limit block 28 is L-shaped, and the two limit blocks 28 are symmetrically located on the upper and lower sides of the transparent protective plate 3, thereby combining to form the above-mentioned sliding channel 29.
