Novel powder adding device

Technical Field

The utility model relates to a powder adding device technical field specifically is a novel powder adding device.

Background

On the production line of the casting shell type back shot, when the combined precoated sand shell core is placed in a sand box for pouring, resin on the surface of the precoated sand can be combusted after contacting molten iron, and tar substances can be generated by the resin which is not completely combusted. The tar substances can be sucked into the bag-type dust remover by the dust removing system. Tar can stick to the surface of the cloth bag when passing through the cloth bag of the dust collector, so that the air permeability of the cloth bag is deteriorated and the filtering function is lost.

In the prior art, in order to solve the problem that tar is stuck on a cloth bag, a certain amount of calcium hydroxide powder is sprayed into a dust remover, and the calcium hydroxide powder is preferentially coated on the surface of the cloth bag. When the tar contacts the cloth bag, the tar is firstly adsorbed by calcium hydroxide powder and then is subjected to ash removal by a dust remover. The calcium hydroxide powder attached with tar is blown off from the cloth bag. The cloth bag is prevented from being blocked by tar.

However, the feeding screw of the conventional powder feeding device is blocked due to moisture absorption and agglomeration of the calcium hydroxide powder.
