Description

Technical Field

[0001] The invention relates to the technical field of fire dampers, in particular to an air-conditioning smoke exhaust fire damper with a smoke filtering function. Background Art

[0002] Air conditioning smoke exhaust fire damper refers to a device installed in the air conditioning system of a building. Its main function is to automatically close the vents when the temperature of the smoke exhaust fire damper reaches the preset temperature (usually 280 degrees Celsius) in the event of a fire, so as to reduce the speed and scope of the fire spread. At the same time, the device also has the function of preventing smoke from entering other areas, effectively protecting the lives and property of personnel.

[0003] In industrial production, building ventilation and air purification systems, filters and activated carbon plates are key components for removing dust, particulate matter and harmful gases from the air. Usually, these filter components will gradually become clogged as they are used, resulting in reduced airflow and reduced filtering effects, and even affecting the efficiency and life of the entire system. Existing filtration systems mostly use mechanical vibration or fan backwashing to clean the filter. Although this can remove impurities attached to the surface to a certain extent, it still has many shortcomings in practical applications.

[0004] Traditional filter cleaning systems mainly rely on single vibration or airflow impact. This method is often difficult to effectively cover every area of ​​the filter. Especially in the application of large-area filters, it is easy to have local cleaning failures, resulting in the accumulation of particles in certain areas, affecting the overall filtering effect.

[0008] Preferably, the discharge assembly comprises a discharge pipe, a fixing plate is fixed to the outer wall of the discharge pipe, and a filter element is arranged inside the discharge pipe.

[0009] Preferably, a handle is rotated inside the fixed plate, a gear 1 is fixed to the outer wall of the handle, a gear ring is rotated at the bottom end of the discharge pipe, the outer wall of the gear ring is meshed with gear 1, a plurality of gears 2 are rotated inside the discharge pipe, the outer wall of gear 2 is connected to a baffle by bolts, and gear 2 is meshed with the inside of the gear ring.

[0010] Preferably, the control component includes a temperature sensor, the outer wall of the temperature sensor is penetrated into the interior of the valve body, the interior of the valve body is penetrated and connected with a harmful gas detection sensor, a controller is fixed on the upper surface of the valve body, the controller and the harmful gas detection sensor are electrically connected, and the controller and the temperature sensor are electrically connected.

[0011] Preferably, a rotating rod is rotated inside the valve body, a valve plate is fixed on the outer wall of the rotating rod, and the valve plate is arranged inside the valve body. A gear three is fixed on the upper end of the outer wall of the rotating rod, an electric push rod is fixed on the upper surface of the valve body, a rack is fixed on the driving end of the electric push rod, the rack and gear are meshed with three phases, and the electric push rod is electrically connected to the controller.

[0012] Preferably, the linkage component comprises a support block, an outer wall of the support block is fixed to the driving end of the electric push rod, a connecting rod is fixed inside the support block, and a push plate is fixed to the end of the connecting rod.

[0013] Preferably, the jet assembly includes a connecting plate 1, an outer wall of the connecting plate 1 is fixed to an outer wall of the discharge pipe, and the outer wall of the connecting plate 1 is connected to a connecting plate 2 by bolts.

[0014] Preferably, an airbag is fixed to the upper end of the outer wall of the connecting plate 2, the outer wall of the airbag is arranged on one side of the outer wall of the push plate, a plurality of air guide tubes are fixed inside the airbag, a diversion tube is fixed on the outer wall of the air guide tube, a plurality of nozzles are fixed inside the diversion tube, and the outer wall of the nozzle is arranged on one side of the outer wall of the filter.

[0015] Working principle: First, after the motor is started, it drives the rotating rod to rotate, and the protrusions 1 and 2 on the rotating rod hit the connecting block alternately. The vibration force is transmitted to the filter and the activated carbon plate through the telescopic action of the telescopic rod 1 and the telescopic rod 2. The spring helps to reset the connecting block after each impact, thereby ensuring that the filter and the activated carbon plate are continuously vibrated, thereby effectively cleaning the accumulated particles and impurities. At the same time, the filter element inside the discharge pipe further filters the fine impurities generated during the cleaning process. The handle is manually operated, and the opening of the discharge pipe is controlled through the cooperation of gear 1 and the gear ring to discharge the impurities through the discharge pipe. The baffle works in coordination with gear 2 to prevent blockage.

[0016] When the temperature sensor and harmful gas detection sensor detect that the flue gas temperature or harmful gas concentration exceeds the standard, the controller immediately starts the smoke exhaust system. At the same time, the electric push rod moves, driving the rack to move, and through the engagement with gear three, drives the rotating rod to rotate. The valve plate on the rotating rod rotates accordingly, opening the smoke exhaust channel inside the valve body.

[0017] When the electric push rod pushes the supporting block and connecting rod in the linkage component, the airbag is compressed through the push plate. After the airbag is squeezed, high-pressure gas is delivered to the air guide pipe. The gas is evenly distributed through the diverter pipe and finally ejected from the nozzle to further clean the outer wall of the filter, ensuring that stubborn particles are completely removed and improving the filtration efficiency.

[0018] The present invention provides an air-conditioning smoke exhaust fire damper with smoke filtering function. It has the following beneficial effects: 1. The present invention achieves the goal of quickly and effectively cleaning the filter and activated carbon plate through the coordination of the internal structures of the filter cleaning components. At the same time, a multi-stage cam and telescopic rod component is designed to provide different amplitudes or striking forces to ensure that the vibration effect can evenly cover all areas of the filter, reduce the local cleaning blind area of ​​the filter, and solve the problem of reduced air flow and reduced filtration efficiency caused by incomplete filter cleaning and blockage in traditional systems. Vibrations of different frequencies can effectively deal with the accumulation of particles of different particle sizes on the filter, improve the long-term stability and operating efficiency of the system, and especially avoid premature failure of the filter under conditions with high dust concentrations.

[0019] 2. The present invention achieves the goal of quickly discharging impurities cleaned by the cleaning component out of the interior of the valve body through the cooperation between the discharge component and the control component. At the same time, the control component can detect the air quality in real time. Once the safety threshold is exceeded, the smoke exhaust system is immediately started, thereby solving the problems in the prior art of filter overload caused by impurity accumulation, exhaust system hysteresis, and difficulty in real-time monitoring of air quality.

[0020] 3. The linkage component and the jet assembly of the present invention cooperate with each other. When the electric push rod moves, it pushes the pressure plate to squeeze the airbag through the linkage component, so that the jet assembly further cleans the outer wall of the filter, further improving the cleaning effect and the filtration efficiency, and solving the problem that particulate matter still partially remains on the surface of the filter when the filter is cleaned simply by vibration and mechanical impact.
