Embodiment 1

[0013] Embodiment 1: see figure 1 , figure 2 , a screw feeder with an overflow seal, including a conveying channel 2 and a screw propulsion shaft 5 matched and sleeved in the conveying channel 2, and a driving motor, and a feeding port 14 is arranged on one end of the conveying channel 2, A discharge port 15 is provided on the lower side of the other end of the conveying channel 2, and a congestion detection mechanism is arranged at the discharge port 15, and the congestion detection mechanism includes an overflow port arranged at a symmetrical position between the side wall of the conveying channel 2 and the discharge port 13. The overflow port and the discharge port are symmetrically arranged, which can monitor the blockage of the material in the machine at the first time, and send an alarm and signal in time. An elastic pressing device and a switch element 9 cooperating with the elastic pressing device are arranged inside the overflow port 13, and the switching element 9 ...

Abstract

The invention relates to the field of material conveying in powder production industry, in particular to a screw feeder with an overflow hole seal. The screw feeder comprises a conveying passage, a screw propeller shaft fitly nested in the conveying passage, and a drive motor. The top of one end of the conveying passage is provided with a feed hole. The bottom of the other end of the conveying passage is provided with a discharge hole. A jam detection mechanism is disposed at the discharge hole and comprises an overflow hole in the side wall of the conveying passage. An elastic ejector device and a switch element operating with the same are disposed inside the overflow hole, and a circular rubber seal is fixed at the edge of the overflow hole, between a moving plate and a fixed plate. The screw feeder is capable of detecting the jam status inside and sending out an alarm signal, so that a discharger operating with the feeder stops feeding and failure of the screw feeder and scattering of material are avoided.

Description

technical field [0001] The invention relates to the field of material conveying in the milling industry, in particular to a screw feeder, in particular to a screw feeder with an overflow seal. Background technique [0002] In the milling process, the screw feeder is matched with the bin discharger to convey the material. The inside of the screw feeder is a closed space, and the overflow port has no safe sealing device, and is only sealed with an ordinary cover. During the milling process, the air pressure inside the feeder is greater than the outside. When there is too much material in the machine, causing blockage, the feeder has no automatic control mechanism and continues to convey materials from the outlet of the bin, which is very easy to make flour Opening the cover and ejecting the equipment will cause pollution to the working environment and waste of raw materials. In addition, if there is material blockage in the machine for a long time, it will reduce the materia...
