Embodiment Construction

[0028] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0029] Such as Figure 1~3 As shown, the present invention is a selenium oxidation production device, including a forehearth generator 3, an oxidation furnace 11 and a collection box 4;

[0030] The forehearth generator 3 includes a reaction cavity A, and a feeder is connected to the reaction cavity. The feeder includes a feed cavity 2 and a compression cylinder 1, and the compression cylinder 1 passes The bracket is fixed on the outer wall of the feed cavity 2. A compression plate is slidably connected in the feed cavity 2. The compression plate is fixedly connected to the cylinder rod of the compression cylinder 1, and the raw material in the feed cavity 2 is in the cy...

Abstract

The invention relates to a selenium oxidation production device. The selenium oxidation production device comprises a forehearth generator, an oxidation furnace and a collecting box. The forehearth generator comprises a reaction cavity A, a feeding device is connected to the reaction cavity, and a heating assembly A for heating raw materials is arranged in the forehearth generator; the reaction cavity is communicated with the oxidation furnace through a connecting pipe A, a reaction cavity B is formed in the oxidation furnace, and a heating assembly B is arranged in the reaction cavity B; the collecting box is connected with the oxidation furnace through a connecting pipe B and comprises a collecting cavity, a cooling assembly is arranged on the outer wall of the collecting cavity, the collecting box further comprises a collecting assembly, a discharging device is connected to the bottom of the collecting box and comprises a discharging pipe, and a grinding device is arranged in the middle of the discharging pipe; a settling box used for settling dust is further connected to the collecting box, a settling discharging opening is formed in the bottom of the settling box, and a valve is arranged on the settling discharging opening.

Description

Technical field [0001] The invention relates to a selenium oxidation production device, belonging to a reaction furnace device. Background technique [0002] Domestic manufacturers of selenium dioxide basically use two types of production equipment: [0003] One is to weld the furnace body with stainless steel, the feed inlet and the furnace are fed at the same time, two oxidations, one discharge every two hours, low qualification rate, low output, serious pollution, and the operator is easy to inhale selenium dioxide during discharge Dust, and the crude selenium raw materials will produce chloride ions and selenite to corrode the furnace body when heated at high temperatures. The furnace body must be repaired for up to two months. The high temperature flame sprays out the selenium residue on the inner wall of the furnace during welding, which makes the operator Surface skin damage. [0004] The other is the heat preservation of the welded stainless steel cylinder with refractory b...
