Problems solved by technology

Rotary spraying is more important for water mist nozzles, especially for medium and low pressure fine water mist nozzles, because the spray droplets of fixed medium and low pressure fine water mist nozzles are small, the momentum is small, and the spray is not far away. This small momentum spray is difficult to enter The depth of the flame affects the fire extinguishing effect, which seriously hinders the promotion of medium and low pressure water mist fire extinguishing

Embodiment 1

[0039] Embodiment 1: the spraying device driven jointly by the counter-rotating rotating mechanism and the jet-propelling rotating mechanism of the present invention, such as figure 1 , Picture 1-1 and Figure 1-2 shown.

[0040] The rotary spraying device mainly includes a seat body 1 and a spray head body 2 . Wherein: a seat cavity is formed in the seat body 1, one end of the seat cavity is connected to an inlet 11 and an external flow pipe (not shown in the figure), and the other end is an outlet cavity 12, and a filter 13 can be arranged on the inlet 11.

[0041]The nozzle body 2 is a rotor body, in which a fluid channel 21 is provided. The input end of the fluid channel 21 is connected to the seat body 1 through a connection assembly and communicated with the seat cavity, and its output end is connected to several nozzles 22. The spray head body and the nozzles it is provided with are as large as a rotating balance body.

[0042] The connecting assembly can be a rota...

Embodiment 2

[0046] Embodiment 2: It is the combined drive of counterattack type and jet propulsion type of the present invention, and the spraying device with sliding and rotating bearing structure, such as figure 2 and diagram 2-1 shown.

[0047] The self-driven rotary spraying device described in this embodiment also includes a seat body 1, a spray head body 2, a connecting assembly and a driving mechanism. in:

[0048] The seat body 1 is provided with a seat cavity, which includes an inlet 11 and an outlet 12 .

[0049] The structure of the nozzle body 2 is the same as that of the above-mentioned embodiment 1, that is, the nozzle body 2 provided with a cross-shaped body 24, and an ordinary torque-free nozzle 22 and an eccentric nozzle 23 are arranged on it, and the eccentric nozzle 23 forms a jet propulsion type rotation Drive mechanism.

[0050] The drive mechanism also includes a paddle-shaped impeller with inclined blades.

[0051] The difference between this embodiment and E...

Embodiment 3

[0052] Embodiment 3: It is the structure of another spraying device with a counter-rotating drive mechanism of the present invention, see image 3 .

[0053] The spraying device mainly includes a seat body 1 and a spray head body 2a. in:

[0054] The seat body 1 is also provided with a seat cavity, and is provided with an inlet 11 and an outlet 12, and the inlet 11 is provided with a filter 13 .

[0055] The spray head body 2a can be a rotating body, and a fluid channel 21a is arranged therein. The input end of the fluid channel 21a is rotatably connected with the seat body 1 and communicated with it through a connecting assembly. Several nozzles 22a are arranged on the outer periphery of the spray head body 2a.

[0056] The self-driven rotary spraying device also includes a driving mechanism, which can be a paddle-shaped impeller 4 disposed in the pressure chamber between the seat body 1 and the spray head body 2a, thereby forming a counter-rotating driving mechanism.

Abstract

The invention discloses a self-driving rotational flusher, comprising a base and a nozzle body; the inlet of the base is connected with an outside fluid delivery pipe; a fluid flow passage is arranged in the nozzle body; at least one nozzle and / or muzzle are / is arranged on the outlet end of the fluid flow passage; the inlet end thereof is rotatably connected with the base through connecting pieces and is communicated with a base cavity; the device is also provided with a driving mechanism; the driving mechanism at least comprises a driven impeller; the driven impeller is arranged in a fluid cavity with pressure between the base and the nozzle body; the driving mechanism and the nozzle body rotate as a whole. The invention can also arrange an eccentric muzzle that can produce eccentric torque on the nozzle body; the jetting pushing function and the superposition driven by the driven impeller can speed up the rotating of the nozzle body; the nozzle body drives the nozzle, the muzzle or a spray rod which is arranged on the nozzle body to rotate, thus achieving good spraying and jetting effects. The self-driving rotational flusher can use water, oil or other liquid as well as gas / liquid fluids or multi-phase fluids.

Description

technical field [0001] The invention relates to a spraying device, especially a self-driven rotary spraying device, which is mainly used in the field of fire protection, especially relates to a rotary spraying head or a rotary spraying device used in an automatic fire extinguishing system, and can also be used for spray dust removal, spray drying, spraying Sprinkler irrigation and other rotary spraying. Background technique [0002] The nozzle is used to spray fire extinguishing agent at the end of the automatic fire extinguishing system pipeline, and can also be used for spray dust removal, spray drying, spray irrigation and so on. Traditional water mist nozzles or foam nozzles or fine water mist nozzles are fixed nozzles, which are unevenly sprayed due to structural limitations, and there is a spray dead angle in the protected area. The solution is rotary spraying, which requires the use of rotary sprinklers. The rotational power of traditional rotary sprinklers is driven...
