Description

Technical Field

[0001] This utility model belongs to the technical field of high temperature cut-off protection devices, specifically a high temperature cut-off protection device for acid regeneration. Background Technology

[0002] Acid regeneration (such as hydrochloric acid and sulfuric acid regeneration) is a key environmental protection process in industries such as metallurgy and chemicals. Its core is the separation of metal ions from waste acid to achieve acid recycling. In acid regeneration processes with inherently high temperatures and risks (such as the roasting furnace stage), reaction temperatures can reach 800-1200℃, and concentrated acids and acidic gases (such as HCl) are involved. If the temperature gets out of control, it may cause violent acid volatilization, equipment corrosion and leakage, and even explosions and burns to personnel. Therefore, it is essential to equip the system with a "high-temperature cut-off protection device" to quickly cut off the heat source or feed when the temperature exceeds the limit, preventing the escalation of the danger.

[0003] However, the following problems were found in the implementation of the relevant technologies: the existing devices use exposed buttons or simple protective covers. The exposed buttons have no physical isolation, and accidental touch by personnel or scratching by tools may trigger the protection, causing the equipment to shut down in an emergency. Although simple protective covers (such as snap-on ones) can prevent accidental touch, in an emergency, the cover must be opened before operation, which increases the response time and may delay the handling of dangerous situations.

[0004] Therefore, we propose a high-temperature cut-off protection device for acid regeneration. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a high-temperature cut-off protection device for acid regeneration, which has the advantages of effectively preventing unauthorized personnel from accidentally touching the button by covering it with a cover plate, and fixing the position of the cover plate by rotating the limit block during long-term operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature cutoff protection device for acid regeneration, comprising a heat-insulating base, a box body fixedly connected to the upper surface of the heat-insulating base, a controller fixedly connected to the inner surface of the box body, a temperature sensor fixedly connected to the inner surface of the box body, a probe fixedly connected to the outer surface of the temperature sensor, the box body further comprising a control panel, the control panel having several control buttons, sliding plates fixedly connected to both sides of the control buttons, springs fixedly connected inside the sliding plates, a slider fixedly connected to the other end of the springs, a cover plate fixedly connected to the outer surface of the slider, a pressure plate fixedly connected to the front surface of the cover plate, an opening provided on the pressure plate, a rotating seat fixedly connected to the heat-insulating base, a rotating rod rotatably connected to the upper surface of the rotating seat, and a limit block fixedly connected to the outer surface of the rotating rod.

[0007] Preferably, the slider is slidably connected to the slide plate.

[0008] Preferably, the cover plate is a glass plate, and the pressure plate is provided with anti-slip texture.

[0009] Preferably, the opening includes a circular hole and a rectangular hole, the cross-sectional dimension of the opening is larger than the cross-sectional dimension of the rotating rod and the limiting block, and the rotating rod, the limiting block and the opening are movably connected.

[0010] Preferably, a baffle is fixedly connected to the upper surface of the slide plate.

[0011] Preferably, an audible and visual alarm light is fixedly connected to the upper surface of the box.

[0012] Preferably, the side surface of the box is provided with a heat dissipation window, and a filter screen is fixedly connected to the outer surface of the heat dissipation window.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the cooperation of a sliding plate, spring, slider, cover plate and pressure plate, can effectively prevent unauthorized personnel from accidentally touching the button when not in use by covering the button with the cover plate, thereby reducing the risk of sudden cut-off, accidental start-up or leakage caused by misoperation. In high temperature, high corrosion environment or vibration location, the cover plate can prevent accidental operation caused by accidental vibration or collision. At the same time, when in use, the operator only needs to press the cover plate to achieve quick and intuitive use.

[0014] 2. This utility model, through the cooperation of pressure plate, opening, rotating seat, rotating rod and limiting block, allows for short-term operation without additional fixing steps. Simply press the cover plate to operate the button. In long-term operation, the operator does not need to press the cover plate continuously. The position of the cover plate can be fixed by rotating the limiting block, freeing up the hands to focus on button operation and avoiding hand pain and decreased operation accuracy caused by prolonged force.

[0018] like Figures 1 to 4 As shown, this utility model provides a high-temperature cut-off protection device for acid regeneration, including a heat-insulating base 1, a box 2 fixedly connected to the upper surface of the heat-insulating base 1, a controller 3 fixedly connected to the inner surface of the box 2, a temperature sensor 4 fixedly connected to the inner surface of the box 2, a probe 5 fixedly connected to the outer surface of the temperature sensor 4, the box 2 also includes a control panel 6, a number of control buttons 7 are provided on the control panel 6, sliding plates 8 are fixedly connected to both sides of the control buttons 7, a spring 9 is fixedly connected inside the sliding plate 8, a slider 10 is fixedly connected to the other end of the spring 9, a cover plate 11 is fixedly connected to the outer surface of the slider 10, a pressure plate 12 is fixedly connected to the front surface of the cover plate 11, an opening 13 is provided on the pressure plate 12, a rotating seat 14 is fixedly connected to the heat-insulating base 1, a rotating rod 15 is rotatably connected to the upper surface of the rotating seat 14, and a limit block 16 is fixedly connected to the outer surface of the rotating rod 15.

[0019] Specifically, slider 10 is slidably connected to slide plate 8.

[0020] Furthermore, the cover plate 11 is specifically a glass plate, and the pressure plate 12 is provided with anti-slip texture.

[0021] Furthermore, the opening 13 includes a round hole and a rectangular hole. The cross-sectional dimension of the opening 13 is larger than the cross-sectional dimension of the rotating rod 15 and the limiting block 16. The rotating rod 15, the limiting block 16 and the opening 13 are movably connected.

[0022] It is worth noting that a baffle 17 is fixedly connected to the upper surface of the slide plate 8 to block the cover plate 11.

[0023] It is worth noting that an audible and visual alarm light 18 is fixedly connected to the upper surface of the box 2 for emitting an audible and visual alarm.

[0024] It is worth mentioning that the side surface of the box 2 is provided with heat dissipation windows, and a filter screen is fixedly connected to the outer surface of the heat dissipation windows for heat dissipation and to reduce the accumulation of internal temperature.

[0025] Among them, controller 3, temperature sensor 4, probe 5, control panel 6, and control buttons 7 and 18 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller 3, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0026] Working principle: During use, the housing 2 is installed on the outside of the equipment, and the probe 5 is installed inside the equipment. The temperature sensor 4 continuously collects the temperature of key points through the probe 5 and transmits it to the control unit in the controller 3. The controller 3 compares the actual temperature with the set safe temperature and limit temperature, calculates the difference and the rate of change. If the temperature exceeds the safe threshold or exceeds the allowable rate of increase, the actuator will act quickly after triggering to close the inlet valve, cut off the pump, cut off the power, or switch to a safe working condition to prevent the acid from continuing to be transmitted or reacted at high temperature. At the same time, the audible and visual alarm light 18 is triggered. After confirming the cause and restoring the conditions, the system can be manually or automatically reset to return to the ready state before normal operation.

[0027] When the operation requires the control button 7 on the control panel 6, the cover plate 11 must first be pressed down by the pressure plate 12. The pressure on the cover plate 11 compresses the spring 9 through the slider 10, and at the same time, the slider 10 drives the cover plate 11 to slide down, thus exposing the control button 7. The operator can then operate the control button 7. When not in use, the spring 9 continues to apply elastic force to the slider 10, pushing the slider 10 to drive the cover plate 11 to slide up, thus blocking the control button 7. If the operator needs to operate for a long time, the pressure plate 12 can be pressed down until it passes through the rotating rod 15 and the limiting block 16. Then, by rotating the rotating rod 15 and the limiting block 16, the limiting block 16 blocks and restricts the pressure plate 12 from springing back up, thus eliminating the need to continuously press the pressure plate 12.
