Embodiment 1

[0036] see Figure 1-5 , in an embodiment of the present invention, a smelting furnace with tail gas treatment for rare earth metal production, including a furnace body 1, an exhaust hose 101, a water tank 2 and an exhaust pipe 201, and the middle upper end of the water tank 2 is fixed in a horizontal direction A filter plate 3 is installed, and the internal positions of the filter plate 3 are arranged in equal rows and fixedly installed with several filter tubes 4 up and down. Exhaust filter assembly 5;

[0037] Each set of filter assemblies 5 includes a guide channel 501 , a casing 502 , a guide channel 503 , a flow control assembly 504 capable of controlling the flow of exhaust gas, and a net flow assembly 505 capable of purifying exhaust gas.

[0038] In the embodiment of the present invention, activated carbon powder 6 is filled between every two adjacent groups of filter assemblies 5 and the inner wall of each filter tube 4;

[0039] The active carbon powder 6 here and i...

Embodiment 2

[0044] see Figure 5 Compared with Embodiment 1, this embodiment of the present invention differs in that each group of flow control components 504 includes a rotating shaft 5041 , a balance plate 5042 and a contact block 5043 .

[0045] In the embodiment of the present invention, each rotating shaft 5041 is rotatably mounted on the inner wall of each housing 502 in a front-rear horizontal direction, and a balance plate 5042 is fixedly installed around the outer surface of each rotating shaft 5041. Each balance plate 5042 are in a horizontal static equilibrium state under normal circumstances, the outer surface of the left end of each balance plate 5042 is surrounded by a filter screen, and the top position of the tail of the right end of each balance plate 5042 is fixedly equipped with a contact block 5043. The appearance of the block 5043 is in the shape of a letter T in a longitudinal section;

[0046] The balance plate 5042 here is to absorb and filter the exhaust gas int...

Embodiment 3

[0049] see Figure 5-7 Compared with Embodiment 1, the embodiment of the present invention differs in that each set of net flow components 505 includes a fixing plate 5051 , an air bag 5052 and a cleaning agent 5053 .

[0050] In the embodiment of the present invention, each fixing plate 5051 is fixedly installed in the middle of the upper end of the inner wall of each housing 502 in the front and rear horizontal direction. Airbags 5052 are fixedly installed on the inner surface of the top side of the plate 5051, and the outer surface of the top side of each airbag 5052 is normally attached to the inner wall of each housing 502, and the inner position of each airbag 5052 is pre-installed Purifier 5053;

Abstract

The invention provides a rare earth metal production smelting furnace with a tail gas treatment function, the smelting furnace comprises a furnace body, an exhaust hose, a water tank and an exhaust pipe, a filter plate is horizontally and fixedly mounted at the middle upper end of the water tank, and a plurality of filter pipes are fixedly mounted in the filter plate in an equally adjacent manner and vertically penetrate through the filter plate. A plurality of filter assemblies capable of filtering tail gas are fixedly mounted on the inner wall of each filter pipe in the vertical direction in a mutually adjacent penetrating and communicating manner. Each filter assembly comprises a flow guide channel, a shell, a drainage channel, a flow control assembly capable of controlling flowing of the tail gas and a flow purification assembly capable of purifying the tail gas. According to the rare earth metal production smelting furnace with the tail gas treatment function, harmful substances in the tail gas can be thoroughly treated, and the potential safety hazard that the exhaust pipe exhausts harmful gas can be eliminated.

Description

technical field [0001] The invention relates to the technical field of rare earth metal processing, and more specifically relates to a smelting furnace with tail gas treatment for rare earth metal production. Background technique [0002] Existing smelting furnaces are basically made for iron ore, so there is no exhaust gas treatment device. Some rare earth metals will produce a large amount of harmful gas during the smelting process, which will harm the human body when the cover is opened. cause great harm to the environment. [0003] In view of the above problems, regarding the technical problem that the smelting furnace cannot perform tail gas treatment, after a large number of searches, we found a smelting furnace with tail gas treatment for rare earth metal production with the patent number CN201811578759.2, including a base, and the upper end of the base is fixed The support rod is connected, the furnace body is fixedly connected to the outside of the rotating shaft, ...
