Abstract

The utility model relates to a novel fan, which comprises a casing and an impeller. The impeller is fixed inside the casing. A nozzle is installed on the casing. The head of the nozzle extends into the casing, and the end of the nozzle is connected with a water supply pipe. The device is simple in structure and easy to operate, and can effectively clean the surface of the impeller of the fan, prevent fouling of the inner wall of the fan and the impeller, prolong the operation period of the fan, and improve the benefit of the enterprise.

Description

A new type of fan

technical field

The utility model relates to an air supply device, in particular to a novel fan.

Background technique

The impeller of the original converter dust removal fan is easy to collect dust and scale during operation, resulting in fan vibration and short operation cycle. Shutdown for manual cleaning of fan impellers, and more than 2 hours per month to find fan balance, resulting in increased maintenance costs, affecting converter production, and causing economic losses to the enterprise.

Contents of the invention

The utility model overcomes the deficiencies in the prior art, and provides a novel fan with simple structure and not easy to scale.

In order to solve the above problems, the utility model adopts the following technical solutions:

The utility model relates to a novel fan, which includes a casing and an impeller. The impeller is fixed inside the casing. A nozzle is installed on the casing. The head of the nozzle extends into the casing, and the end of the nozzle is connected with a water supply pipe.

The difference between the height of the nozzle installation position and the height of the impeller axis is 1/4 of the impeller diameter.

Compared with the prior art, the beneficial effects of the utility model are:

When the fan is running, the nozzle can spray water on the impeller, so that the inner metal surface of the fan is wrapped in a water film during operation, which hinders the contact and deposition of dust particles with the surface of the impeller, inhibits the scaling speed of the impeller and the inner wall of the fan, and prolongs the life of the fan. The operation cycle of the fan is shortened, thereby reducing the maintenance cost and improving the enterprise benefit.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Figure 2 is the left side view of Figure 1.

Detailed ways

A new type of fan, as shown in Figure 1 and Figure 2, includes a casing 1 and an impeller 2, the impeller 2 is fixed inside the casing 1, and four DN15 spiral fan nozzles 3 are horizontally arranged on the fan casing 1, and the nozzles 3 The head protrudes into the casing 1 and keeps a certain distance from the impeller 2, and the end of the nozzle 3 is connected with the water supply pipe. The difference between the height of the installation position of the nozzle 3 and the height of the shaft center of the impeller 2 is 1/4 of the diameter of the impeller 2 .

When the fan is running, the nozzle 3 can produce a water column with a water volume of about 2m ³ /h and a water pressure of 0.3Mpa to 0.5Mpa in a 90° fan-shaped water column, so that the impeller 2 generates atomized water in the radial direction and covers the entire impeller and the fan casing. The side inner wall and the inner metal surface of the fan are completely wrapped in water film during operation, which hinders the contact deposition of dust particles and the surface of the impeller, thereby inhibiting the scaling speed of the impeller and the inner wall of the fan, and prolonging the operation period of the fan.

Claims (2)

1. a novel fan comprises casing and impeller, and impeller is fixed in casing inside, it is characterized in that, nozzle is installed on the casing, and nozzle head stretches in the casing, and nozzle end is connected with water pipe.

2. a kind of novel fan according to claim 1 is characterized in that, the gap of the height in the height of nozzle mounting point and impeller axle center is the 1/3-1/4 of impeller diameter.
