Description

Spray Axial Fan

technical field

The invention belongs to the technical field of textile air-conditioning facilities, and in particular relates to a spray axial flow fan, which is used to deliver fresh air to a textile workshop and simultaneously adjust the humidity of the air in the textile workshop.

Background technique

Chinese utility model patent authorization announcement numbers CN2085044Y and CN2622435Y both disclose spray axial flow fans with humidification function, the latter focuses on the improvement of the structure of the blades, and the technical point of the former is to add a mechanical atomizer in the hub of the impeller In addition, a water supply and drainage mechanism is added in the shell, and an atomizing diffuser is added to the main cylinder, so that the air supply and humidification can be carried out simultaneously. The spray axial flow fan of this structure is shown in Fig. 4: comprises main cylinder body 1, is positioned at the air inlet side of main cylinder body 1 and is connected with main cylinder body 1 (butted) air collecting cylinder body 2, The motor 3, the impeller 4, the water supply pipe 5 and the atomizer 6 are arranged in the air collecting cylinder 2, the air collecting cylinder 2 and the main cylinder 1 are installed on the bottom frame 21, and the motor 3 is installed on the collector through the motor bracket 31. In the air cylinder body 2, the impeller 4 is fixed to the motor shaft of the motor 3 extending into the main cylinder body 1 through its hub 41, the atomizer 6 is arranged in the hub 41, and one end of the water supply pipe 5 is connected with the water source pipeline, and the other One end extends between the inner and outer tapered sleeves 61 and 62 of the atomizer 6 . The specific working principle can be found in the specification of CN2085044Y.

The air supply and humidification process of the spray axial flow fan with the above structure is embodied in this way, the water supply pipe 5 directly supplies the water introduced by the water source pipeline such as the tap water pipeline to the atomizer 6, that is, enters the inner cone of the atomizer 6 cover 61, and then reach the impeller web of impeller 4, and then reach the rear side of the impeller web through the water inlet hole 42 on the impeller web, because there is a gap between the impeller web and the water retaining plate 43, the water in A flow channel is formed in the gap. At this time, a centrifugal force is generated under the high-speed rotation of the impeller 4. Under the action of the centrifugal force, the water blocked by the water retaining plate 43 is thrown toward the circumferential direction of the impeller 4, so that the atomizer 6 The water is atomized, and the atomized water mist is cut and hit by the impeller 4 to form a water mist curtain. During this process, some water droplets collide with each other to form larger water droplets, and these larger water droplets are driven by the impeller 4. The tip of the blade is thrown to the drain tank 7 of the main cylinder 1, collected in the drain tank 71 of the drain tank 7 and discharged from the drainage interface 711 connected to the drain tank 71; formed by the action of the impeller 4 The water mist curtain is mixed with the air introduced by the air collecting cylinder 2 to generate supersaturated air, and the supersaturated air is ejected from the air outlet of the main cylinder 1, thus completing the whole process of air supply and humidification.

The spray axial flow fan with the above-mentioned structure has been proved by practice to have the following two deficiencies: one is that the structure is relatively complicated, not only the atomizer 6 must be installed in the hub 41, but also the impeller 4 corresponding to the impeller 4 of the main cylinder 1 must be installed. A (circle) drainage groove 7 is processed at the sharp part, and a drainage cylinder 71 is arranged on the drainage groove 7, so that the difficulty of processing the main cylinder 1 increases, and in addition, the workload of processing and installing the atomizer 6 Equally bigger; the 2nd, atomization effect is poor, and water source waste is big, is not enough to embody energy saving, and this is because atomizer 6 is difficult to digest the water supplied by water supply pipe 5, promptly is difficult to fully atomize the water supplied by water supply pipe 5. Therefore, it is necessary to improve the spray axial flow fan of this structure, and the technical solution to be introduced below is based on this premise.
