Description

Technical Field

[0001] This utility model relates to a mixer, and more particularly to a proportioning mixer for mixing media. Background Technology

[0002] Current mixers use a mixed channel, where various liquids and gases that need to be mixed are mixed in the same channel by pressure transmission based on the pressure difference generated by the different flow rates of the liquid and gas. However, this mixing method is prone to pressure fluctuations. When pressure fluctuations occur, backflow, gas blockage, and liquid blockage will occur, affecting the mixing state. Utility Model Content

[0003] This invention provides a proportioning mixer for mixing media, which can ensure a stable state between the media to be mixed.

[0004] This utility model adopts the following technical solution: a proportioning mixer for mixing media, comprising a mixer body connected to a gas-liquid mixing chamber at the rear of the mixer body, a central flow channel at the axial center of the mixer body, the inlet IV of the central flow channel being located on the front end face of the mixer body, the main body of the central flow channel being connected along the axial center of the mixer body to the middle position of the head side of the liquid mixing chamber located at the center of the tail of the mixer body, and several branch channels and several suction channels being distributed laterally around the central flow channel, the branch channels and suction channels being evenly distributed and spaced apart from each other, the inlet of the branch channels... Inlet I and several inlets II of the suction channels are located on the front end face of the mixer body. The main body of each branch channel is located in the mixer body and is connected to the head side of the liquid mixing chamber. The tail side of the liquid mixing chamber has an outlet that is connected to the gas-liquid mixing chamber. The main body of each suction channel passes through the mixer body and is connected to the gas-liquid mixing chamber. Several liquid suction channels are evenly distributed longitudinally in the mixer body. Each liquid suction channel corresponds to each branch channel. The inlet III of each liquid suction channel is located on the side of the mixer body. The main body of each liquid suction channel is located in the mixer body and is perpendicularly connected to the side of the corresponding branch channel to form a Venturi mixing device.

[0005] Furthermore, the central flow channel of this invention is surrounded by six branch channels and six intake channels, which are evenly distributed around each other in a ring shape.

[0006] Furthermore, the central flow channel of this utility model is a funnel-shaped channel.

[0007] Furthermore, the mixer body of this invention has six liquid suction channels evenly distributed longitudinally, with each liquid suction channel corresponding to each branch channel.

[0008] Furthermore, each of the flow channels of this utility model includes a front flow channel and a rear flow channel. The front flow channel and the rear flow channel form an angle. The head of the front flow channel is set as the inlet I of the flow channel. The middle part of the front flow channel is vertically connected to the corresponding liquid suction channel to form a Venturi mixing device. The tail of the front flow channel is connected to the liquid mixing chamber through the inclined rear flow channel.

[0009] Furthermore, the air intake channel of this utility model is configured as a conical channel.

[0010] Furthermore, the mixer body is designed to be conical.

[0011] This invention has the following beneficial effects: By adopting the above technical solution, the air intake channel, central channel, liquid intake channel, and branch channels of this invention are all independent channels, enabling the mixing of different media in specific proportions. This allows for flexible configuration and the processing of various media such as gases, liquids, or ultrafine powders. It effectively avoids backflow, air blockage, and liquid blockage caused by pressure fluctuations during the mixing process. The mixer body of this invention is cone-shaped, with a funnel-shaped central channel. Each branch channel includes a front channel and a rear channel, forming an angle. The head of the front channel is designated as the inlet I of the branch channel. The middle of the front channel is perpendicularly connected to the corresponding liquid intake channel to form a Venturi mixing device. The tail of the front channel is connected to the liquid mixing chamber via an inclined rear channel. This utilizes the Venturi principle and the ejection principle of liquids and gases, ensuring rapid flow and stable mixing of various media, thus greatly improving mixing efficiency. The initial pressure of the medium in each channel of this invention can be arbitrarily set according to actual needs. By preset the medium pressure in each channel, the mixing ratio of different media can be dynamically changed to meet diverse application requirements. This invention has a simple and reliable structure, and the adjustment of various ratios can be easily achieved, thereby significantly reducing manufacturing costs. Attached Figure Description

[0019] The method of using this utility model: Taking its application in a foam fire extinguishing system as an example, water is first introduced from the inlet of the central channel 3 and the inlets of the six branch channels 5. The water flows into the central channel 3 and the six branch channels 5. The water flowing into the central channel 3 is propelled by the negative pressure generated within the central channel 3, creating an ejection effect that propels the water into the liquid mixing chamber 4. Simultaneously, the water flowing into the branch channels 5 experiences negative pressure due to the Venturi effect, drawing the foam liquid flowing into the suction channel 9 into the front section 51 of the branch channel 5, and then through the rear section 52 into the liquid mixing chamber 4. The water and foam liquid flowing into the liquid mixing chamber 4 mix, achieving a foam liquid mixing ratio between 0.5% and 6%. This mixed foam solution then enters the gas-liquid mixing chamber 2, where it mixes with air entering through the air intake channel 6, resulting in foaming and significantly increasing the foaming ratio, expected to reach 4-8 times.
