Embodiment 1

[0036] Such as figure 1 The fan shown includes a bell-shaped air inlet 1, a ring cutting disc knife 2, a cutting blade 5, a cutting blade seat 4, and an impeller 3, and the ring cutting disc knife 2 is connected to the horn through a fixing bolt 7. The small mouth end of the air inlet 1 of mouth shape, the two planes of the circular cutting disc knife 2 and the cutting blade 5 are basically close to each other, and the cutting blade 5 is fastened on the cutting blade seat 4 through the connecting screw 6, On the impeller 3, a plurality of blades 8 (such as image 3 As shown), the cutting blade seat 4 is welded on the corresponding blade 8.

[0037] The above-mentioned air inlet is in the shape of a bell mouth, and the air inlet is in the shape of a conical arc, which has the smallest air inlet resistance and the highest efficiency.

[0038] The impeller of the above-mentioned fan has been trial-manufactured many times, and the influence of the air volume and air pressure of ...

Embodiment 2

[0051] The blower fan adopting the structure shown in embodiment 1 will have an area no greater than 0.01m 2 , or the area of ​​the material is not greater than 0.01m 2 And the length is not more than 50cm, or different kinds of materials whose length is not more than 50cm and diameter is not more than 8mm are cut and chopped respectively, and the corresponding chopped materials are transported out from the fan; the cutting blade of the fan and the ring cutter The two planes of the disc knife are basically close to each other. When the cutting blade rotates with the impeller and blades, the material is chopped. At the same time, due to the action of centrifugal force, the material is thrown at the small end of the air inlet that is fixed in the shape of the bell mouth when it is thrown out. On the inner ring mouth of the circular cutting disc knife, a secondary cutting is formed between the rotating cutting blade and the circular cutting disc knife to ensure that all the mater...

Abstract

The invention provides a material cutting and conveying method and a fan used by the method. According to the method, the fan is adopted to cut material, and the cut material is conveyed outside from the fan; when the material is cut and conveyed, the air quantity of the fan is controlled to be within the range of 1800-2000m<3> / h, and the air pressure is controlled to be within the range of 1200-1500Pa; a cutting blade of the fan basically clings to the two planes of a ring cutting disc cutter; when rotating along with an impeller and a blade, the cutting blade cuts the material, and the material is thrown onto an inner ring hole of the ring cutting disc cutter fixed at a small hole end of a horn mouth-shaped air inlet when being thrown out under the action of centrifugal force, so that secondary cutting is formed between the rotary cutting blade and the ring cutting disc cutter, the material is guaranteed to be completely cut, and the cut material is sent to the outside of the air inlet of the fan by the impeller. The fan is low in manufacturing cost, good in cutting effect, stable in conveying performance and long in service life.

Description

technical field [0001] The invention relates to a material cutting and conveying method, in particular to a material cutting and conveying method suitable for a fan and the fan used. Background technique [0002] At present, in the food, chemical, pharmaceutical, greening, sanitation and other industries, special fans are widely used to transport materials. Due to the large differences in the shape, size and characteristics of the materials to be transported, some special materials need to be chopped before being processed. delivery. However, it is difficult for ordinary fans to apply cutting and conveying on the same fan. Contents of the invention [0003] The object of the present invention is to provide a material cutting and conveying method which can not only chop the material but also transport the material on the fan, and the fan used in the method. This material cutting and conveying method is mainly aimed at the area of ​​the material not greater than 0.01m 2 ,...
