Detailed Description

The invention is further described with reference to the following figures and embodiments.

Referring to fig. 1, a device for preventing aluminum liquid pollution includes: connect the setting board 1 and locate the sediment hook unit 2 that blocks of connecting the setting board 1 below, block sediment hook unit 2 and include a plurality of first sediment hooks 21 that block that set up side by side, first sediment hook 21 that blocks includes montant 211, the one end of montant 211 is fixed in connect on the setting board 1, the other end of montant 211 is buckled and is extended formation horizontal pole 212. The first slag trap hook 21 is made of round steel. The number of the first slag blocking hooks 21 is 3-5. The connection and positioning plate 1 is plate-shaped. The thickness of the connecting and positioning plate 1 is 8-12 mm. The first slag blocking hook 21 is formed by bending round steel with the diameter of 8-12 mm. The device for preventing aluminum liquid pollution further comprises a handle 3, and the handle 3 is arranged at one end, far away from the slag blocking hook unit 2, of the connecting and positioning plate 1; the handle 3 comprises a first rod 31, one end of the first rod 31 is fixed on the connecting and positioning plate 1, and the other end of the first rod 31 is bent and extended to form a second rod 32. Specifically, in the embodiment, the invention is composed of a connecting and positioning plate 1, a slag blocking hook unit 2 and a handle 3. The number of the first slag blocking hooks 21 is determined according to the size of the cross section of the launder, and the larger the cross section of the launder is, the more the number of the first slag blocking hooks 21 is. The length of the first rod 31 is related to the depth of the launder, the bottom of the first rod 31 is 3-6cm away from the bottom of the launder, and the preferable scheme is as follows: the bottom of the first rod 31 is 5cm from the bottom of the launder.
