Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a balanced proportion mixing device. Background Art

[0002] The balanced proportion mixing device is a type of fire-fighting equipment used to provide foam mixture to the fire-fighting system. It uses a normal pressure non-bladder foam storage tank, which avoids the risk of rupture and reduces the cost of the pressure vessel. It can continuously prepare foam mixtures with more precise mixing ratios and carry out fire-fighting operations. Therefore, it is an ideal equipment for large and medium-sized foam fire-fighting projects.

[0003] Existing balanced proportional mixing devices are usually integrated, with various pipes and valves arranged together on a mounting plate, which reduces the time for assembling pipes and valves on the construction site. However, it also results in the surprising weight of the balanced proportional mixing device, making it difficult to make minor adjustments to its position on site, affecting installation efficiency.

[0009] A further improvement is that the rotation drive device includes: a limit platform arranged on the rotating screw, a limit ring platform arranged on the guide sleeve, a pressure bearing arranged between the limit platform and the limit ring platform, and a drive device is also arranged between the rotating screw and the frame.

[0010] A further improvement is that the driving device includes a worm wheel arranged on the rotating screw and located on one end of the outer side of the guide sleeve, a worm rotatably arranged on the frame, and a rotating handle arranged on the worm.

[0011] A further improvement is that the guide device comprises a guide block arranged on the support sleeve and a guide groove opened on the guide sleeve for preventing the support sleeve from rotating.

[0012] A further improvement is that the mixing device includes: a liquid inlet pipe arranged on the frame, a pump group arranged on the frame and connected to the liquid inlet pipe, a water inlet pipe arranged on the frame, a mixer arranged on the water inlet pipe, and a discharge pipe arranged on the mixer, one end of the liquid inlet pipe is connected to the mixer and the other end is connected to the foam storage tank.
