Detailed Description

The present invention is described below in terms of embodiments with reference to the accompanying drawings to assist those skilled in the art in understanding and realizing the invention. Unless otherwise indicated, the following embodiments and technical terms therein should not be understood to depart from the background of the technical knowledge in the technical field.

Example 1: a screw conveyer, see Figs. 1-3, comprises a housing 310 for forming a conveying passage, a screw blade 315 for driving the movement of powder in the conveying passage, and an iron removing device 313.

In the prior art, when the spiral blade 315 is fixed on the rotating shaft 314, the spiral conveying device is a belt-rotating shaft type spiral conveying device. When the central axis of the helical blade 315 is not provided with a rotating shaft, the helical conveying equipment is shaftless helical conveying equipment.

The housing 310 is provided with a first article-taking opening and an article-taking opening closing door 312 for closing the first article-taking opening.

The iron removing device 313 includes an iron sucker installed at a matching position of the housing 310 such that an iron scrap retaining recess is formed at a position corresponding to the iron sucker on an inner wall surface of the housing 310, and the iron scraps adsorbed on the iron sucker can be taken out through the first taking-out opening. It should be noted that the utility model discloses the gap should be dodged with being equipped with between the rotatory virtual entity that forms of helical blade 315 to the deironing device that increases to avoid influencing helical blade 315's rotation.

Preferably, a second pick-up opening capable of forming the iron piece retention concave portion is provided in the middle of the iron sucker, and the second pick-up opening forms a part of the first pick-up opening. Fig. 3 shows a structure of the iron attracting device, the lower bottom surface of the iron attracting device is a cambered surface, and when the iron attracting device is arranged on the shell, the lower bottom surface of the iron attracting device and the inner wall of the shell are externally connected with a virtual cylinder. When the screw blade 315 drives the powder entering the housing 310 through the inlet 317 to move, the powder and the iron pieces therein are pushed to move toward the outlet 318 side of the housing 310. When the iron sucker adsorbs the iron filings, the iron filings in the virtual cylinder form resistance points, but the powder pushes the iron filings to move on the adsorption surface of the iron sucker. When reaching iron fillings and detaining the concave part department, iron fillings move into iron fillings from the virtual cylinder and detain in the concave part, and at this moment, the resistance of iron fillings to the powder reduces. Especially, at the edge of the adsorption surface, if the iron filings are separated from the iron attracting device, the friction force of the powder to the iron filings needs to be greater than the magnetic attraction force of the iron attracting device to the iron filings. The edge of the magnet corresponding to the second pick-up opening can also form the edge of the suction surface, corresponding to the shape of the magnet in fig. 3.

Preferably, the iron scrap retention concave part is a groove or a through hole, and the iron sucker is arranged on the closed door of the fetching opening. The object-taking opening closing door 312 can be installed on the housing 310 in a hinged or other movable connection manner, or can be installed on the housing 310 in a detachable connection manner in a bolt connection manner or a clamping manner.

Preferably, the first object taking opening is arranged on the upper wall surface of the casing 310, the tubular seat 311 is installed at a position of the casing 310 corresponding to the first object taking opening, the iron sucker is installed on the tubular seat 311, the first object taking opening is formed between the iron sucker and the inner wall of the tubular seat 311, and the object taking opening closing door 312 is detachably connected with the tubular seat 311. Referring to fig. 2, the access opening closing door 312 is overlapped on the tube seat 311.

Preferably, the iron removing device can select a permanent magnet or an electromagnet. If the iron removing device selects the electromagnet, the iron attracting device corresponds to the iron core of the electromagnet.
