Description

Technical Field

[0001] The present application relates to the technical field of safety protection of heating equipment, and in particular to a protective door for heating equipment. Background Art

[0002] In the fields of metallurgy, ceramics, chemical industry, etc., products usually need to be heated using heating equipment to achieve sintering and densification of the products. During the heating process, the heating equipment is closed and isolated from the outside world to ensure the heating effect and safety. However, after the heating is completed, the equipment needs to be cooled to a safe temperature before the staff can open the protective door to take out the products. In long-term work, it is inevitable that the staff will make misoperations, such as opening the protective door when the equipment has not completely cooled down, which may lead to safety accidents such as burns. Therefore, how to prevent the staff from mistakenly opening the protective door when the equipment has not completely cooled down and improve operational safety has become a technical problem that needs to be solved urgently in this field.

[0003] At present, although some heating equipment has taken corresponding safety protection measures, such as setting warning signs and using safety locks, these measures still cannot completely prevent workers from operating them incorrectly. Therefore, it is necessary to develop a safer and more practical heating equipment protective door to solve the above problems. Utility Model Content

[0004] In order to improve the safety of the equipment, the present application provides a heating equipment protective door.

[0005] This application provides a heating equipment protective door, which adopts the following technical solutions:

[0006] A protective door for heating equipment includes a protective door body and a thermal expansion material, and is characterized in that the thermal expansion material is arranged on the protective door, and is used to expand when the temperature is high to jam the protective door through an anti-misopening structure, and contract after cooling to release the lock of the protective door.

[0007] By adopting the above technical solution, when the temperature of the heating equipment is high, the thermal expansion material will expand and the protective door will be stuck through the anti-misopening structure to prevent misopening or accidental opening, which is conducive to preventing heat leakage and protecting the safety of operators and equipment.

[0008] Optionally, the anti-misopening structure includes a card slot provided on the protective door body and a card block cooperating with the card slot, wherein the card block is connected to the thermal expansion material. When the thermal expansion material expands, the card block is inserted into the card slot to lock the protective door.

[0009] By adopting the above technical solution, when the thermal expansion material expands, the card block will be stuck in the card slot, locking the protective door firmly. The protective door can be locked automatically without manual intervention, which is conducive to improving the convenience and efficiency of operation.

[0010] Optionally, the card slot is arranged on the edge of the protective door body, and the card block is arranged on a side of the thermal expansion material close to the card slot.

[0011] By adopting the above technical solution, the card slot is set at the edge of the protective door body, so that the card block and the card slot can fit more closely together, which can increase the stability and sealing of the protective door and prevent heat leakage and debris from entering the equipment.

[0012] Optionally, a temperature sensor is further included, which is arranged on the protective door body and is used to detect the temperature near the protective door and trigger an alarm device when the temperature reaches a set value.

[0013] By adopting the above technical solution, the temperature sensor can detect temperature changes near the protective door in real time. When the temperature exceeds the set value, it may mean that the heating equipment has an abnormal condition, such as overheating or failure. Through timely detection and alarm, problems can be discovered in advance to avoid equipment damage or accidents.

[0014] Optionally, the alarm device includes an audible and visual alarm for emitting an audible and visual alarm signal when the temperature reaches a set value.

[0015] By adopting the above technical solution, the sound and light alarm can quickly attract people's attention by emitting a high-brightness light signal and a loud sound. When the temperature reaches the set value, the sound and light alarm triggers, which can promptly alert the operator or nearby people that there may be an abnormality in the heating equipment and appropriate measures need to be taken.

[0016] Optionally, the thermal expansion material is a shape memory alloy, which can change shape when the temperature changes to drive the anti-misopening structure.

[0017] By employing this technical solution, the thermal expansion material changes shape in response to temperature changes, thereby actuating the opening and closing of the anti-accidental opening mechanism. When the temperature reaches a set value, the thermal expansion material expands, causing the anti-accidental opening mechanism to open, thereby allowing the protective door of the heating device to be opened. This prevents equipment damage or accidents caused by excessive temperatures.

[0018] Optionally, the protective door body is made of heat-insulating material to reduce the transfer of heat to the external environment.

[0019] By adopting the above technical solution, the thermal insulation material can effectively reduce the transfer of heat and prevent the heat inside the heating device from being lost to the external environment. This can improve the energy utilization efficiency of the heating device, reduce energy waste, and achieve the purpose of energy saving.

[0020] Optionally, an observation window is provided on the protective door body for observing the internal conditions of the heating equipment without opening the protective door.

[0021] By adopting the above technical solution, the observation window provides a safe observation channel, avoiding the safety risks that may be caused by opening the protective door. Through the observation window, the operator can directly observe the internal conditions of the heating equipment and understand the equipment's operating status without having to open the protective door and access the high-temperature equipment.

[0022] In summary, the present application includes at least one of the following beneficial technical effects of the heating equipment protective door:

[0023] 1. Because the present invention uses thermal expansion material, it expands at high temperatures to lock the protective door through the anti-accidental opening structure, and contracts after cooling to release the lock of the protective door. This effectively prevents workers from accidentally opening the protective door when the equipment is not fully cooled, thereby improving operational safety.

[0024] 2. In the present invention, shape memory alloy is preferably used as the thermal expansion material. Since the shape memory alloy can change shape when the temperature changes, it can reliably drive the anti-misopening structure, further improving the safety performance of the protective door.

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0030] An embodiment of the present application discloses a protective door for heating equipment.

[0031] Reference Figure 2 and Figure 3A protective door for a heating device includes a protective door body 1, a protective door 2, and a protective member 3. The protective door body 1 is connected to the protective door 2, and the protective member 3 is connected to the protective door 2. The protective door body 1 provides support for the protective door 2, and the protective member 3 prevents the protective door 2 from being opened accidentally.

[0032] Reference Figure 1 and Figure 2 A temperature sensor 11 and an alarm device 12 are provided on the main body 1 of the protective door 2. The temperature sensor 11 is provided on the main body 1 of the protective door 2 for detecting the temperature near the protective door 2 and triggering the alarm device 12 when the temperature reaches a set value. The alarm device 12 includes an audible and visual alarm for emitting an audible and visual alarm signal when the temperature reaches a set value. The main body 1 of the protective door 2 is made of thermal insulation material to reduce the transfer of heat to the external environment. An observation window 13 is provided on the main body 1 of the protective door 2 for observing the situation inside the heating equipment without opening the protective door 2.

[0033] Reference Figure 1 and Figure 2 , the thermal insulation material can effectively reduce the transfer of heat and prevent the heat inside the heating equipment from being lost to the external environment; the temperature sensor 11 can detect the temperature changes near the protective door 2 in real time. When the temperature exceeds the set value, it may mean that the heating equipment has an abnormality, such as overheating or failure. Through timely detection and alarm, problems can be discovered in advance to avoid equipment damage or accidents; the sound and light alarm can quickly attract people's attention by emitting high-brightness light signals and loud sounds. When the temperature reaches the set value, the triggering of the sound and light alarm can promptly remind the operator or surrounding personnel, which means that the heating equipment may have an abnormality and corresponding measures need to be taken; the observation window 13 can provide a safe observation channel, avoiding the safety risks that may be caused by opening the protective door 2. Through the observation window 13, the operator can directly observe the situation inside the heating equipment and understand the operating status of the equipment without having to open the protective door 2 to contact the high-temperature equipment.

[0034] Reference Figure 1 and Figure 2 The protective door 2 is provided with a connecting groove, and the protective member 3 is located in the connecting groove. When the temperature is high, the protective member 3 locks the protective door 2. After cooling, it shrinks to release the lock of the protective door 2. When the temperature of the heating equipment is high, the protective member 3 locks the protective door 2 to prevent it from being opened accidentally or by mistake, which helps prevent heat leakage and protect the safety of operators and equipment.

[0035] Reference Figure 2 and Figure 3The protective member 3 includes an anti-incorrect opening structure 31 and a thermal expansion material 32. The anti-incorrect opening structure 31 includes a slot 311 provided on the main body 1 of the protective door 2 and a block 312 that cooperates with the slot 311. The block 312 is connected to the thermal expansion material 32. When the thermal expansion material 32 expands, the block 312 engages with the slot 311 to lock the protective door 2. The slot 311 is provided on the edge of the main body 1 of the protective door 2, and the block 312 is provided on the side of the thermal expansion material 32 near the slot 311. The thermal expansion material 32 is a shape memory alloy that changes shape when the temperature changes to activate the anti-incorrect opening structure 31.

[0036] Reference Figure 2 and Figure 3 When the thermal expansion material 32 expands, the latch 312 snaps into the slot 311, securely locking the protective door 2. This automatically locks the protective door 2 without manual intervention, improving operational convenience and efficiency. The thermal expansion material 32 changes shape in response to temperature changes, thereby opening or closing the anti-incorrect opening mechanism 31. When the temperature reaches a set value, the thermal expansion material 32 expands, causing the anti-incorrect opening mechanism 31 to open, thereby opening the protective door 2 of the heating device. This prevents equipment damage or accidents caused by excessive temperatures.

[0037] The working principle of the protective door for heating equipment in this embodiment is as follows: During operation of the heating equipment, when the temperature is high, the thermal expansion material 32 expands, driving the locking block 312 to engage with the locking slot 311, thereby locking the protective door 2 and preventing personnel from accidentally opening it. When the equipment cools, the thermal expansion material 32 contracts, and the locking block 312 disengages from the locking slot 311, releasing the lock on the protective door 2 and allowing personnel to open the protective door 2 normally.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
