Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, specifically a fire safety alarm device for dust removal units. Background Technology

[0002] A dust collector unit is usually a system composed of a variety of dust collection devices. Its working principle combines the working principles of each component device. The working principle of dust collectors and dust collector units mainly relies on physical principles such as gravity, inertia, centrifugal force, filtration and electrostatic force. Through a multi-stage dust collection and cleaning system, gas purification and dust removal are achieved.

[0003] Occasionally, sparks may occur during the operation of the dust collector unit, causing the dust filter chamber to catch fire. Therefore, an alarm device is required. Existing alarm devices usually sound an alarm when a fire occurs. However, the fire extinguishing water source is far from the dust collector, which limits the fire extinguishing efficiency. In emergencies, it is impossible to quickly provide sufficient water pressure and volume to the dust collector, and it cannot respond quickly when a fire occurs. It is necessary to automatically activate the fire extinguishing program, which increases the risk of fire spreading.

[0004] Therefore, it is necessary to provide a new fire safety alarm device for dust removal units to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a fire safety alarm device for dust removal units to solve the problems mentioned in the background art.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Please see Figure 1-5 As shown, a fire safety alarm device for a dust collector unit includes a dust collector body 1 and a cover 2. The cover 2 is located on the top of the dust collector body 1. A spark detector 3 is installed on the inner wall of the dust collector body 1 to detect sparks during dust collection. The spark detector 3 typically uses optical, electromagnetic, or other advanced sensing technologies. Its core function is to capture the light emitted by the spark. It uses a high-speed photosensitive element to detect the characteristic spectrum of the spark. When a spark is generated, it emits light of a specific wavelength. The detector can quickly capture this light signal change and convert it into an electrical signal for processing and analysis. This is existing technology and will not be elaborated here. A temperature sensor 4 is installed on one side of the dust collector body 1 to monitor the temperature during dust collection. When the ambient temperature changes, the sensitive element inside the temperature sensor 4 will generate a corresponding electrical signal change. After amplification and processing, this signal can be converted into a temperature reading or signal. The temperature sensor 4 is used to monitor the temperature of the dust collector unit and its surrounding environment in real time. This is existing technology.

[0027] The control panel 5 is installed on one side of the dust collector body 1. The control panel 5 is a fire alarm controller in the prior art. It is responsible for receiving, displaying and transmitting fire alarm signals. When the spark detector 3 and the temperature sensor 4 detect abnormal signals, these signals will be transmitted to the fire alarm controller. The control panel 5 can extinguish the fire 60 seconds after one of the spark detector 3 or the temperature sensor 4 sends a signal, so as to avoid the problem of one of them being damaged and affecting fire safety. The power supply of the control panel 5 is taken from the corresponding dust collector body 1. A mounting plate 6 is fixed on one side of the dust collector body 1. An alarm 7 for fire alarm is installed on the top of the mounting plate 6. The alarm 7 is electrically connected to the control panel 5. Once the control panel 5 confirms that it has received a fire alarm signal, such as a spark signal or an abnormal temperature signal exceeding the preset threshold, it will immediately activate the alarm 7 to sound an alarm and emit a strong audible and visual signal to alert the operator and take emergency measures.

[0028] The water inlet pipe 8 is located on one side of the dust collector body 1. The water inlet pipe 8 is connected to the nearest fire hydrant as a fire extinguishing water source, which shortens the distance between the fire extinguishing water source and the dust collector and improves the fire extinguishing efficiency. In an emergency, it can quickly provide the dust collector with sufficient water pressure and volume to ensure the fire extinguishing effect. One end of the water inlet pipe 8 is connected to a solenoid valve 9, which is electrically connected to the control panel 5. One end of the solenoid valve 9 is connected to a first water outlet pipe 10, and the outside of the first water outlet pipe 10 is connected to a first atomizing nozzle 11 for fire extinguishing. The solenoid valve 9 is opened by controlling the control panel 5, and the fire extinguishing is carried out through the first water outlet pipe 10 and the first atomizing nozzle 11.

[0029] The first valve 12 is installed on the outside of the water inlet pipe 8. One end of the first valve 12 is fixed with a first flange 13. A filter screen 14 is installed on one side of the first flange 13. The filter screen 14 prevents the atomizing nozzle from becoming clogged, thus avoiding the problem of fire extinguishing failure.

[0030] A second flange 15 for installing the first valve 12 is fixed to the outside of the water inlet pipe 8. The first flange 13 and the second flange 15 are fixed with bolts to install the first valve 12. A clamp 16 for installing the filter screen 14 is fixed to the inner wall of the first flange 13. The filter screen 14 is clamped on the outside of the clamp 16. An adapter 17 is installed on the outside of the water inlet pipe 8. One end of the adapter 17 is connected to a connecting pipe 18. One end of the connecting pipe 18 is connected to a second valve 19. One end of the second valve 19 is connected to a second water outlet pipe 20. A second atomizing nozzle 21 is provided at one end of the second water outlet pipe 20. The second valve 19 can be used for manual fire extinguishing when the solenoid valve 9 is damaged. Emergency fire extinguishing can be carried out through the second water outlet pipe 20 and the second atomizing nozzle 21.

[0031] A first mounting bracket 22 is fixed to the outside of the water inlet pipe 8. The water inlet pipe 8 is installed on one side of the dust collector body 1 through the first mounting bracket 22. A second mounting bracket 23 is fixed to the outside of the first water outlet pipe 10 and the second water outlet pipe 20. The first water outlet pipe 10 and the second water outlet pipe 20 are installed on one side of the dust collector body 1 through the second mounting bracket 23. A dust discharge port 24 is provided at the bottom of the dust collector body 1. A support frame 25 is fixed to the outside of the dust collector body 1.

[0032] Working Principle: During operation, this device uses a spark detector 3 to detect sparks during dust removal and a temperature sensor 4 to monitor the temperature. Once the control panel 5 confirms that a fire alarm signal has been received, such as a spark signal or an abnormal temperature signal exceeding a preset threshold, it will immediately activate the alarm 7, emitting a strong audible and visual signal to alert the operator and prompt emergency measures. Simultaneously, it will stop the dust collector 1 from operating. Then, the control panel 5 will control the solenoid valve 9 to open, allowing fire extinguishing through the first water outlet pipe 10 and the first atomizing nozzle 11. The control panel 5 can also be activated by the spark detector 3 or... One of the temperature sensors 4 sends a signal and controls the solenoid valve 9 to open for fire extinguishing after sixty seconds, avoiding the problem of one sensor malfunctioning and affecting fire safety. The filter screen 14 prevents the atomizing nozzle from clogging and failing to extinguish the fire. The second valve 19 can be used for manual fire extinguishing if the solenoid valve 9 is damaged. Emergency fire extinguishing is carried out through the second water outlet pipe 20 and the second atomizing nozzle 21. The water inlet pipe 8 connects to the nearest fire hydrant as a fire extinguishing water source, shortening the distance between the fire extinguishing water source and the dust collector, improving fire extinguishing efficiency. In emergency situations, it can quickly provide sufficient water pressure and volume to the dust collector to ensure the fire extinguishing effect.
