Embodiment Construction

[0012] Please refer to Figure 1 to Figure 4 Shown is the preferred embodiment of the lead melting device of the present invention. The lead-melting device 100 comprises a material storage area 1, a first lead-melting area 2, a first lead-out valve 3, a second lead-melting area 4, a second lead-out valve 5, a vacuum system, a control cabinet 7, and a frame 8, The vacuum system includes a vacuum pump 6, a cooling pipe connected to the inlet of the vacuum pump, a filter and a negative pressure regulating valve.

[0013] The material storage area 1 provides the molten raw material for the first lead melting area 2, and the molten raw material in this embodiment is lead ingot. The melted lead ingots are placed in the storage area 1 in advance, and the production amount for one day or other certain period of time is stored at one time according to the production requirements, so as to ensure that the storage area 1 will not be opened for feeding during the production process.

Abstract

The invention discloses a lead melting device which comprises a storing area, a first lead melting area and a first lead discharging valve, wherein the first lead melting area comprises a first melted lead container and a first heating device capable of heating the first melted lead container; the first lead discharging valve is connected with the first melted lead container; the storing area comprises a feeding device and a shielding hood; the shielding hood is used for sealing the feeding device and the first melted lead container; the feeding device can be used for supplying lead to the first melted lead container in a batch-wise manner in a pre-arranged period, so as to carry out a plurality of lead melting period; and the lead melting device further comprises a vacuum pump capable of vacuuming the storing area and the first melted lead container. As the internal spaces of the storing area and the first melted lead container are sealed, and the storing area and the first melted lead container are connected with the vacuum pump to improve the degrees of vacuum of the storing area and the first melted lead container, the generation rate of lead skim generated when melted lead is oxidized is reduced.

Description

【Technical field】 [0001] The invention relates to a melting device for easily oxidized metals with a low melting point, in particular to a lead melting device. 【Background technique】 [0002] Lead is a metal extracted by humans earlier. It is the softest heavy metal and one of the densest metals. Lead has good ductility and is easily alloyed with other metals. Lead alloys are widely used in the manufacture of lead-acid battery plates, and lead pipes and lead plates are used as protective materials. [0003] An existing lead melting device comprises a furnace body, a bracket supporting the furnace body and a heating device for heating the furnace body. Lead, lead alloy or crude lead is directly put into the furnace body for melting. The furnace body is an open type, and the molten lead is directly exposed to the air and is quickly oxidized to form lead slag. At the same time, it produces toxic gas that pollutes the environment and endangers human health. [0004] In view ...
