Problems solved by technology

The edge of the blade on the impeller of the conventional star unloader is parallel to the axis of the impeller. The falling process of the material is carried out simultaneously with the rotation of the impeller. The impeller and the casing will have a shearing effect on the material, especially when the material is mixed with floc or This phenomenon is especially obvious for velvet materials. The cutting method is linear shearing, and the shearing force is relatively large, so there will be a muffled sound of "bang bang" when the machine is running. In severe cases, the unloader will be blocked. These situations occur Usually, the power of the motor is increased to complete the forced shearing, which will increase the wear of the blades of the impeller, and if the shell is opened for cleaning, it will seriously affect the working efficiency

Embodiment

[0025] Such as figure 1 As shown, a star unloader includes: a housing 1, an impeller shaft 6, an impeller 2, a scraper 4 and a driving device (not shown in the figure), wherein: the upper end of the housing 1 is provided with a feeding port 3 and The lower end is provided with a discharge port 5, and the impeller shaft 6 is rotatably set in the housing 1, and one end of it protrudes outside the housing 1 to connect with the driving device. The driving device is composed of a motor and a reducer. The output end of the device is connected with the end of the impeller shaft 6 protruding from the casing to drive the rotation of the impeller shaft 6 . Such as figure 2 As shown, the impeller 2 includes blades 22 and a hub 21, and the blades 22 are six and evenly distributed on the outer wall circumference of the hub 21, and each blade 22 is offset by an angle relative to the axis of the hub 21, and the angle between the two is 6 °, the impeller 2 is fixedly sleeved on the impelle...

Abstract

The invention discloses a star-like unloader comprising a housing, an impeller shaft and an impeller. The upper and lower ends of the housing are provided with a feed hole and a discharge hole respectively. The impeller shaft driven to rotate by a drive device is disposed within the housing. The impeller fixedly sleeves the impeller shaft; blades of the impeller skew off the axis of a hub at a certain angle. Two scrapers are arranged on the inner wall of the housing on two radial sides of the axis of the hub of the impeller. When the blades of the impeller rotate to the corresponding parts of the scrapers, gaps are reserved between the front edges of the scrapers and the front edges of the blades of the impeller. Linear shearing of materials is converted into point shearing, so that shearing force is decreased and the impeller is effectively prevented from jamming.

Description

technical field [0001] The invention relates to a star unloader. Background technique [0002] The star unloader device is the main equipment for dust removal, air supply and other equipment feeding. The star unloader is suitable for powdery materials and granular materials. It has a compact structure, beautiful appearance, and is easy to use. It runs smoothly and is widely used in environmental protection, metallurgy, chemical industry, grain, food and other industrial sectors. The edge of the blade on the impeller of the conventional star unloader is parallel to the axis of the impeller. The falling process of the material is carried out simultaneously with the rotation of the impeller. The impeller and the casing will have a shearing effect on the material, especially when the material is mixed with floc or This phenomenon is especially obvious for velvet materials. The cutting method is linear shearing, and the shearing force is relatively large, so there will be a muff...
