Description

Technical Field

[0001] This utility model relates to the field of vulcanizing fan technology, specifically a vulcanizing fan fault trip alarm device. Background Technology

[0002] A sulfurizing blower is a device used in industrial production processes to remove sulfide-containing waste gas. It is mainly applied in industrial environmental protection fields such as coal-fired power plants and steel mills. By fully contacting the sulfide-containing flue gas with liquid droplets, it achieves desulfurization and dust removal, thereby reducing environmental pollution and protecting the ecological environment. The working principle of a sulfurizing blower mainly includes three steps: gas intake, purification, and exhaust. It uses mechanical principles to draw in sulfide-containing waste gas, treats it, and then discharges the purified waste gas, achieving the purpose of removing sulfides. The sulfurizing blower consists of an impeller section, a casing section, an air inlet, a bearing housing, and a motor. The impeller consists of two impellers with different rotation directions, each with 10 airfoil blades and an arc-shaped front disc. Through dynamic translational correction, it operates smoothly.

[0003] In practical use, the aforementioned existing technologies are prone to failure and shutdown due to external factors and the aging of their own components. If the workshop happens to be unattended, the gas flow in the desulfurization tower will be affected, which may result in the gas not being effectively discharged, thereby reducing the purification effect. In severe cases, the gas may flow through the tower tray, at which point the gas will exert an impact force on the tower tray and packing. Over a long period of time, this may cause the tower tray and packing to loosen or even collapse. Therefore, it does not meet the current requirements. To address this, we propose a desulfurization fan failure and shutdown alarm device. Utility Model Content

[0004] The purpose of this invention is to provide a fault trip alarm device for a vulcanizing fan, so as to solve the problem mentioned in the background art that the vulcanizing fan cannot promptly alarm and notify the staff to maintain it in time when it fails to trip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vulcanizing fan fault trip alarm device, the device comprising:

[0006] A base, on which a vulcanizing fan is fixedly installed, and a column is installed on one side of the base. A power control box is installed at the front end of the column and the power control box is fixed to the column by bolts.

[0007] The fault alarm mechanism includes a pressure sensor, a current sensor, a voltage sensor, a gateway, a microcontroller, and an audible and visual alarm. The signal output terminals of the pressure sensor, current sensor, and voltage sensor are electrically connected to the input terminal of the gateway. The signal output terminal of the gateway is electrically connected to the input terminal of the microcontroller. The output terminal of the microcontroller is electrically connected to the input terminal of the audible and visual alarm.

[0008] An adjustment seat is located above the power control box, and the adjustment seat slides in conjunction with the lifting adjustment groove on the front end face of the column. The audible and visual alarm is located at the front end of the adjustment seat.

[0009] Preferably, the pressure sensor is installed in the pressure system of the vulcanizing blower, and the current sensor and voltage sensor are installed on the power supply of the vulcanizing blower.

[0010] Preferably, the output of the gateway is also connected to the user's mobile terminal via a wireless communication network.

[0011] Preferably, a fixed rod extending into the lifting adjustment groove is fixedly installed at the rear end of the adjusting seat. A movable rod extending to the outside is slidably installed inside the fixed rod. A return spring is fixedly installed between the fixed rod and the movable rod. A limit slider is fixedly provided at one end of the movable rod. The limit slider has a T-shaped structure and is embedded in the inner wall of the lifting adjustment groove.

[0012] Preferably, positioning rods are fixedly provided on both sides of the rear end of the adjustment seat, and positioning holes are provided on both sides of the column located in the lifting adjustment groove, and the positioning rods are inserted into the positioning holes.

[0013] Preferably, a shock-absorbing mechanism is provided between the audible and visual alarm and the adjustment seat. The shock-absorbing mechanism includes a damping buffer and a shock-absorbing spring. The two ends of the damping buffer are fixed to the audible and visual alarm and the adjustment seat, respectively, and the shock-absorbing spring is located outside the damping buffer.

[0014] Preferably, the audible and visual alarm consists of a flashing light and a buzzer.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model installs a pressure sensor in the pressure system of the vulcanizing blower to monitor internal pressure changes. Current and voltage sensors are installed on the power supply of the vulcanizing blower to monitor current and voltage fluctuations. Abnormal increases or decreases in pressure, or abnormal fluctuations in current or voltage, may indicate a blower malfunction or unstable operation, potentially leading to a shutdown. The signal is converted by a gateway and sent to a microcontroller, which activates an audible and visual alarm, emitting flashing lights and a warning sound to notify nearby personnel for immediate action. Simultaneously, a fault alarm signal is transmitted wirelessly to the mobile terminal of safety personnel, enabling timely access to fault information and facilitating prompt troubleshooting and repair of the vulcanizing blower, minimizing equipment downtime. This ensures stable system operation.

[0017] 2. To avoid obstruction of the audible and visual alarm by various pieces of equipment in the workshop, thus affecting information transmission, this utility model adopts a lifting and adjusting mechanism for the audible and visual alarm. When adjusting the height of the audible and visual alarm, pulling the alarm causes the fixed rod and movable rod to extend, thereby moving the positioning rod out of the positioning hole. After losing positioning, the audible and visual alarm is moved up and down to reach the appropriate position. After releasing, the fixed rod and movable rod retract under the reset spring, thereby driving the positioning rod on the inner side of the adjusting seat to move towards the positioning hole until the two are reconnected, ensuring the stability of the audible and visual alarm in that position. This adjustment structure is convenient and easy to operate, which not only avoids workshop equipment from obstructing the alarm mechanism, but also avoids inconvenient and inaccurate positioning when the alarm is triggered due to an excessively high installation position.

[0018] 3. This utility model incorporates a shock-absorbing mechanism for the audible and visual alarm. To prevent damage caused by vibrations from cleanroom equipment being transmitted to the audible and visual alarm, a shock-absorbing mechanism is installed between the adjusting seat and the audible and visual alarm. This mechanism consists of a damping buffer and a shock-absorbing spring. The shock-absorbing spring absorbs vibration through its contraction and deformation. Combined with the damping buffer, this reduces the impact of vibration on the audible and visual alarm, thereby improving its service life. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-4 One embodiment of this utility model provides: a vulcanizing fan fault trip alarm device, the device comprising:

[0026] A base 1 is provided, a vulcanizing fan 2 is fixedly installed on the top of the base 1, a column 3 is installed on one side of the base 1, a power control box 4 is installed at the front end of the column 3, and the power control box 4 is fixed to the column 3 by bolts.

[0027] The fault alarm mechanism includes a pressure sensor, a current sensor, a voltage sensor, a gateway, a microcontroller, and an audible and visual alarm 5. The pressure sensor is installed in the pressure system of the vulcanizing blower, and the current sensor and voltage sensor are installed on the power supply of the vulcanizing blower. The signal output terminals of the pressure sensor, current sensor, and voltage sensor are electrically connected to the input terminal of the gateway. The signal output terminal of the gateway is electrically connected to the input terminal of the microcontroller. The output terminal of the microcontroller is electrically connected to the input terminal of the audible and visual alarm 5. The output terminal of the gateway is also connected to the user's mobile terminal through a wireless communication network.

[0028] Adjustment seat 8 is located above power control box 4, and adjustment seat 8 slides in cooperation with lifting adjustment groove 6 on the front end face of column 3. Audible and visual alarm 5 is located at the front end of adjustment seat 8.

[0029] If there is an abnormal increase or decrease in pressure, or abnormal fluctuations in current or voltage, it may indicate that the fan is faulty or unstable, which may lead to a fault shutdown. The signal is converted by the gateway and sent to the microcontroller, which then activates the audible and visual alarm 5, emitting a flashing light and warning sound to notify the surrounding staff to handle the situation quickly. At the same time, the fault shutdown alarm signal is sent to the mobile terminal of the safety personnel through the wireless communication network, so as to obtain fault information in a timely manner, facilitate the on-site staff to troubleshoot in a timely manner, and quickly repair the vulcanizing fan to reduce equipment downtime.

[0030] Please see Figure 1 , Figure 2 and Figure 3 A fixed rod 9 extending into the lifting adjustment groove 6 is fixedly installed at the rear end of the adjusting seat 8. A movable rod 10 extending to the outside is slidably installed inside the fixed rod 9. A return spring 11 is fixedly installed between the fixed rod 9 and the movable rod 10. A limit slider 12 is fixedly installed at one end of the movable rod 10. The limit slider 12 has a T-shaped structure and is embedded in the inner wall of the lifting adjustment groove 6. Positioning rods 13 are fixedly installed on both sides of the rear end of the adjusting seat 8. Positioning holes 7 are provided on both sides of the column 3 located in the lifting adjustment groove 6. The positioning rods 13 are inserted into the positioning holes 7. This adjustment structure is convenient and easy to operate. It can not only avoid workshop equipment from obstructing the alarm mechanism, but also avoid the installation position being too high, which would make it inconvenient to accurately locate the alarm.

[0031] Please see Figure 3A shock-absorbing mechanism is provided between the audible and visual alarm 5 and the adjusting seat 8. The shock-absorbing mechanism includes a damping buffer 14 and a shock-absorbing spring 15. The two ends of the damping buffer 14 are fixed to the audible and visual alarm 5 and the adjusting seat 8 respectively, and the shock-absorbing spring 15 is located outside the damping buffer 14. The shock-absorbing spring 15 absorbs the vibration force by contraction and deformation. Together with the damping buffer 14, the impact of vibration force on the audible and visual alarm 5 is reduced, thereby improving the service life.

[0032] The audible and visual alarm 5 consists of a flashing light and a buzzer.

[0033] Working principle: In order to avoid the obstruction of the sound and light alarm 5 by various equipment in the workshop and thus affect the transmission of information, the sound and light alarm 5 adopts a lifting adjustment mechanism. When adjusting the height of the sound and light alarm 5, by pulling the sound and light alarm 5, the fixed rod 9 and the movable rod 10 are extended, thereby causing the positioning rod 13 to move out of the positioning hole 7. After losing positioning, the sound and light alarm 5 is moved up and down to reach the appropriate position. After being released, the fixed rod 9 and the movable rod 10 are retracted under the reset of the return spring 11, thereby driving the positioning rod 13 on the inside of the adjusting seat 8 to move towards the positioning hole 7 until the two are reconnected, ensuring the stability of the sound and light alarm 5 in this position.
