Description

Technical Field

[0001] The invention relates to the field of fire extinguishing agent production equipment, in particular to a wetting agent adding device for producing water-based fire extinguishing agent. Background Art

[0002] With the development of technology and the progress of society, fire safety plays an increasingly important role. Fire extinguishing agent is a very important fire-fighting product, which refers to a substance that can effectively destroy the combustion conditions in the burning area, stop the combustion and achieve the purpose of extinguishing the fire. Its fire extinguishing mechanism is that when the fire extinguishing agent is sprayed into the burning area, through a series of physical and chemical reactions, it can cool the burning material; isolate the burning material from oxygen; reduce the oxygen concentration in the combustion area; interrupt the chain reaction of combustion, and ultimately lead to the destruction of the necessary conditions for maintaining combustion, thereby stopping the combustion reaction and playing a role in extinguishing the fire. There are many types of fire extinguishing agents, including foam fire extinguishing agents, liquid fire extinguishing agents, dry powder fire extinguishing agents, etc.

[0003] Water-based fire extinguishers can extinguish initial fires of Class A, B, C, and E (electrical fires). They have long spray distances, high fire extinguishing efficiency, strong resistance to rekindling, certain burn resistance to the human body, and are non-toxic, non-toxic, non-irritating, non-corrosive, and easy to clean. They are ideal firefighting products for homes and crowded public places such as cars, trains, shopping malls, hotels, restaurants, hospitals, cinemas, conference rooms, entertainment venues, airplanes, ships, stations, and docks. Water-based fire extinguishers require the addition of a wetting agent. The main function of the wetting agent in water-based fire extinguishers is to increase the fluidity and coverage of the fire extinguishing agent, making it easier for it to reach the fire source and suppress the flames. At the same time, the wetting agent can also improve the affinity of the fire extinguishing agent with the fire source, enhancing the fire extinguishing effect.

[0004] However, uneven material supply or insufficient mixing in existing wetting agent addition devices may lead to an extension of the production cycle, affecting overall output. Failure to fully disperse and mix the materials may lead to inconsistent product quality, affecting customer satisfaction and market competitiveness. Material leakage or improper flow control may lead to waste of raw materials and increase production costs. Material blockage or uneven flow may cause equipment failure, increasing maintenance costs and downtime. Therefore, those skilled in the art provide a wetting agent addition device for the production of water-based fire extinguishing agents to solve the problems raised in the above background technology.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The material first enters the dispersion cylinder through the feed hopper. The feed hopper is set on both sides of the mounting plate to ensure uniform supply of materials. The stirring mechanism is started by control, and the first servo motor in the stirring mechanism rotates. The first servo motor can drive the driving wheel to rotate. The gears between the driving wheel and the rotating gear plate are engaged with each other. The dispersion cylinder and the dispersion roller surface cooperate with each other. Through high-speed rotation and friction, the material is fully dispersed and mixed. The telescopic cylinder is activated, and the telescopic rod at the output end moves downward, pushing the sealing valve to open. The design of the sealing groove and the sealing gate ensures that the material will not leak during the dispersion process, effectively controlling the flow state of the material. The dispersed solid wetting agent flows into the stirring tank below for subsequent processing, completing the entire addition process;

[0017] 2. The first servo motor is started, the driving wheel begins to rotate, and the rotating gear disk also rotates accordingly. This movement makes the material in the dispersion cylinder fully contact with the dispersion roller and begins to be stirred. A limit gear disk is provided on the side of the dispersion cylinder close to the sealing groove. A plurality of transmission wheels are provided at equal distances between the gear disk and the dispersion cylinder. The transmission wheel is engaged with the gears between the limit gear disk and the dispersion cylinder, so that when the dispersion cylinder rotates, the transmission wheel drives the stirring rod to move accordingly. The stirring rod is fixed under the transmission wheel, and a plurality of stirring blades are evenly provided on the side away from the transmission wheel. When the stirring rod rotates due to the rotation of the transmission wheel, the stirring blades will stir the material in the stirring tank, so that the water-based fire extinguishing agent material fully reacts with the wetting agent, thereby achieving effective mixing and dispersion. Under the action of the stirring blades, the material is continuously stirred and dispersed in the stirring tank in the equipment body until the required uniformity is achieved;

[0018] 3. When the second servo motor starts, its output end begins to rotate, causing the threaded rod to rotate as well. The internal structure of the metering roller is threaded, which cooperates with the threads between the threaded rods. As the threaded rods rotate, the metering roller and the surface of the metering inclined frame cooperate with each other. The movement of the metering roller will apply a certain amount of pressure to the metering inclined frame, thereby regulating the material flow rate. It can accurately control the material conveying volume, ensuring that the material is delivered to the subsequent mixing tank through the through hole at the set speed and quantity, ensuring the material flow and conveying accuracy during the production process, thereby improving overall efficiency and product quality.

[0019] 4. After the third servo motor is started, the output end drives the guide frame through the swing rod, thereby driving the transmission rack on one side to move horizontally on the slide. A meshing relationship is formed between the transmission rack and the drive wheel. The rotation of the drive wheel drives the transmission rack on the other side to slide along the slide. Multiple movable shafts are arranged at equal distances on both sides of the transmission rack. These movable shafts enable the swing plate to swing synchronously through the connected transmission rod. When the transmission rod moves, the connected swing plate will also swing accordingly, thereby realizing the material unloading action. Through the swing of the swing plate, the material is unloaded smoothly, thereby achieving the predetermined conveying or distribution effect. BRIEF DESCRIPTION OF THE DRAWINGS
