Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foam mixers, and more specifically to a portable foam mixer. Background Art
[0002] In the field of fire extinguishing systems, foam fire extinguishing systems are highly favored due to their good fire extinguishing effect and little damage to equipment. As an important part of the foam fire extinguishing system, the development and application of portable foam mixers also reflect the trend of diversification of fire extinguishing systems. Foam mixers can effectively mix water and foam liquid to form foam fire extinguishing agents; foam fire extinguishing agents can quickly cover the fire source, isolate oxygen, and reduce the combustion temperature, thereby quickly controlling and extinguishing the fire. Foam mixers are particularly effective in extinguishing liquid fires, especially flammable liquid fires.
[0003] Foam mixers are usually designed to be portable or vehicle-mounted, which is convenient for rapid deployment and operation at the fire scene. Portable foam mixers are widely used due to their portability and high efficiency. Especially in places such as flammable liquid warehouses, boiler rooms, ships, oil depots, gas stations, chemical plants, etc., due to their special fire risks, the demand for portable foam mixers is more urgent.
[0004] The existing portable foam mixers do not mix the foam evenly, which causes the sprayed foam to fail to achieve the actual fire extinguishing effect, thus affecting the fire extinguishing efficiency.
[0005] Therefore, it is an urgent problem to be solved by those skilled in the art to provide a portable foam mixer that can mix foam evenly and stably generate foam. Utility Model Content
[0006] In order to overcome the deficiencies of the prior art, the utility model aims to provide a portable foam mixer which is easy to carry and has a high foam mixing rate.
[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions, which mainly include:
[0008] A portable foam mixer comprises a body and a filtering device, wherein two ends of the body are respectively a bubble inlet end and a bubble outlet end, a throttling hole is arranged inside the bubble inlet end, an air inlet is arranged at the bubble inlet end, a first interface is installed outside the bubble inlet end, two ends of the filtering device are respectively a bubble inlet pipe and a bubble outlet pipe, a second interface is arranged on the bubble inlet pipe, a filter screen is arranged between the second interface and the bubble inlet pipe, a third interface is arranged on the bubble outlet pipe, a filter screen is arranged between the third interface and the bubble outlet pipe, the bubble outlet pipe is connected to the first interface via the third interface, a foaming net is arranged inside the bubble outlet end, and a spraying device is installed outside the bubble outlet end.
[0009] Preferably, the air inlet is a waist-shaped through hole.
[0010] Preferably, the bubble inlet pipe and the bubble outlet pipe are connected via male and female threads.
[0011] Preferably, the first interface, the second interface and the third interface adopt forest interfaces.
[0012] It can be seen from the above technical solution that, compared with the prior art, the utility model combines a foam mixer and a filtering device together. The forest filtering technology adopted by the foam mixer has an excellent filtering effect. Through the action of the filter, most of the impurities and particulate matter in the water can be removed to make the foam mixture purer; this pure foam mixture can be more effectively mixed with air to produce more and more stable foam, thereby improving the fire extinguishing efficiency, and through the male and female threaded docking method, a close combination with the water flow is achieved.

[0018] Example
[0019] A portable foam mixer, such as Figure 1 to Figure 2As shown, it includes a body 1 and a filtering device 4, wherein two ends of the body 1 are respectively a bubble inlet end 2 and a bubble outlet end 3, a throttling hole 6 is provided inside the bubble inlet end 2, an air inlet port 5 is provided at the bubble inlet end 2, a first interface 9 is installed outside the bubble inlet end 2, two ends of the filtering device 4 are respectively a bubble inlet pipe 13 and a bubble outlet pipe 14, a second interface 10 is installed on the bubble inlet pipe 13, a filter screen 11 is installed between the second interface 10 and the bubble inlet pipe 13, a third interface 12 is installed on the bubble outlet pipe 14, a filter screen 11 is installed between the third interface 12 and the bubble outlet pipe 14, the bubble outlet pipe 14 is connected to the first interface 9 via the third interface 12, a foaming net 7 is provided inside the bubble outlet end 3, and a spraying device 8 is installed outside the bubble outlet end 3.
[0020] In order to further optimize the above solution, the air inlet 5 is a through hole in an oval shape.
[0021] In order to further optimize the above solution, the bubble inlet pipe 13 and the bubble outlet pipe 14 are connected by male and female threads, and the bubble inlet pipe 13 and the bubble outlet pipe 14 are connected by male and female thread docking to ensure a tight connection without leakage.
[0022] In order to further optimize the above solution, the first interface 9, the second interface 10 and the third interface 12 adopt forest interfaces.
[0023] The device is connected to a portable foam water storage barrel through a second interface 10 of a foam inlet pipe 13. A mixture of foam liquid and water passes through a filter device 4 and enters the interior of the main body 1. A Venturi effect occurs inside the main body 1, and external air enters the interior of the main body 1 from an air inlet 5 and mixes with the mixture. The mixture of foam liquid, water and air rapidly flows through a foaming net 7, foams under the action of the foaming net 7 and reaches a certain foaming multiple, thereby improving the mixing quality of foam and water and the foaming multiple, and then is sprayed out from a spraying device 8 through the mesh of the foaming net 7.
[0024] In order to further optimize the above scheme, the foam mixer filter device 4 is mainly composed of two side-by-side DN40 forest connectors, a filter screen 11 and a connecting pipe. The filter screen 11 is located between the two connectors and is tightly combined with the water flow through male and female threaded docking. The internal diameter of the filter is about 60 mm to ensure sufficient flow. At the same time, the length of the pipes at both ends is between 120 and 150 mm to meet the needs of different installation environments.
[0025] In order to further optimize the above solution, a special filter 11 is designed to effectively remove impurities and particulate matter in the water to ensure the purity of the foam mixture. At the same time, the filter can withstand a pressure of up to 0.6 MPa to ensure that there will be no water leakage under high pressure, thereby ensuring the stable operation of the system.
