为保证煤球压制的质量,必须在煤球机喂料斗中保持一定的料位。通常各煤球厂把喂料斗敞开,以便观察料位,往往粉尘飞扬,严重影响工人健康。很多单位为把喂料斗密闭,曾设想安装各种指示器来指示料位的高低,但尚未找到妥善的办法。我们想出了一种简单办法.在喂料斗中插入三根铁线,解决了料位指示问题。示意图如下:三根铁线分别插在喂料斗的不同高度处,当粉料低于铁线时,铁线跳动不止,若料 In order to ensure the quality of the briquettes, it is necessary to maintain a certain level in the billet feeding hopper. The billets are usually open to the feed hopper in order to observe the material level, often dust flying, seriously affecting the health of workers. In order to close the feed hopper, many units have envisaged installing various indicators to indicate the level of the material, but no proper solution has yet been found. We came up with a simple way to insert the three wires in the feed hopper to solve the problem of level indication. Schematic diagram is as follows: Three wire were inserted in the feeding hopper at different heights, when the powder is lower than the wire, the wire beating more than if the material
