Abstract

The utility model relates to a zinc gasifying furnace, which is mainly used for manufacturing zinc powder. The furnace is composed of a furnace chamber, a furnace body, a big crucible, a small crucible, an air door, a smoke channel, etc. The big crucible and the small crucible are arranged on the furnace body side by side, the big crucible is adjacent to the side of the furnace chamber, and the big crucible is connected with the small crucible via a connecting pipe. The small crucible is used to melt zinc, and the big crucible can further heat the molten zinc to gasify. The utility model has the advantages of less investment and obvious effect. After is furnace is stopped, the device has no damage, the dust can be removed easily and the raw materials being used are not limited.

Description

Zinc gasifying furnace

The utility model relates to a kind of device that produces zinc fume in the zinc powder process of making.

Zinc powder is the main raw material of Chemicals such as vat powder, zinc sulfide white, zinc-chrome yellow, in addition, also is widely used in aspects such as organic synthesis, metallurgical industry, battery industry, printing and dyeing industry, coatings industry and agricultural chemicals.The manufacture method of zinc powder is with 1#, 2# zinc ingot metal baking earlier, fusion again, distillation, then through condensation, capture, sieve and get.Production unit has two kinds, and the one, electric furnace, i.e. the fusion of zinc ingot metal, distillation are all carried out in electric furnace; Another kind is a tower tray, and the zinc ingot metal that is about to after the baking drops into fusion in the zinc-melting pool earlier, enters the gasification of silicon carbide tower tray again, and the zinc fume after the gasification enters condenser and cools off under airfree environment, enters after the capture in the vibratory screening apparatus of sealing to sieve again.

Above-mentioned two kinds of devices that produce zinc fume must use 1#, 2# zinc ingot metal, are difficult for using for outer zinc ingot metals such as 4#, 5#, more can not use cadmia, so production cost is higher.In addition, these two kinds of equipment are all invested bigger, and the production cycle is long; Especially tower tray in case cut off the water in the production process, should cause expensive tower tray to be scrapped, and causes unnecessary loss.

The purpose of this utility model is exactly to design a kind of new Zinc gasifying furnace at above-mentioned weak point, and this furnace structure is simple, and cost is lower, and does not add restriction to producing material.

The purpose of this utility model is achieved through the following technical solutions:

Form the utility model by body of heater, Lu Tang, big crucible, little crucible, air door, flue etc., be provided with the stove plate in the stove hall, the stove plate is the decline ladder from outside to inside, and large and small crucible is arranged side by side, and big crucible is arranged near stove hall one side, and be fixed on the body of heater, the stove hall communicates with flue, and air door is located between the big or small crucible respectively, the opposite side of little crucible, and the oral area of big crucible is established crucible cover, establish the zinc fume outlet on the crucible cover, establish one between big crucible and the little crucible and connect pan pipe.Fire door is established in the stove hall outside.Connect the end that pan pipe is positioned at big crucible and be higher than an end that is positioned at little crucible.Also establish a main air door on the flue.

Use principle of the present utility model is such:

To expect that earlier (zinc ingot metal or cadmia) drops in the little crucible, behind the heating and melting, zinc water flows into further heating in the big crucible through connecing pan pipe, because of the close stove hall of cauldron, temperature is than temperature height in the little crucible, and zinc water is gasified, for preventing that zinc fume from spraying from little crucible by connecing pan pipe, injure operator, want a head height so connect pan pipe, one low.

Technical characterstic of the present utility model and positively effect:

1, simple in structure, be easy to make, and less investment;

2, not only can use 1#, 2# zinc ingot metal, also can use outer zinc ingot metals such as 4#, 5# and cadmia to make raw material, greatly reduce production cost;

3, after the blowing out, equipment is harmless, is easy to removal of impurities.

Accompanying drawing and description of drawings:

Accompanying drawing is a structural representation of the present utility model;

1 is fire door, the 2nd among the figure, stove hall, the 3rd, and stove plate, the 4th, big crucible, the 5th, crucible cover, the 6th connects pan pipe, the 7th, little crucible, the 8th, air door, the 9th, body of heater, the 10th, flue, the 11st, main air door, the 12nd, zinc fume outlet.

In conjunction with the accompanying drawings the utility model is further described:

As shown in the figure, the utility model is by body of heater 9, stove hall 2, big crucible 4, little crucible 7, air door 8, flue 10 compositions such as grade, stove plate 3 is located in the stove hall 2, and stove plate 3 is the decline ladder from outside to inside, stove hall peripheral hardware fire door 1, fuel joins on the stove plate 3 through fire door 1, stove hall 2 the most inboard established big crucible 4, is arranged side by side little crucible 7 with big crucible 4, links to each other by connecing pan pipe 6 between big crucible 4 and the little crucible 7, big crucible 4 oral areas are established crucible cover 5, establish zinc fume outlet 12 on the crucible cover 5, big crucible 4, little crucible 7 is fixed on the body of heater 9, and flue 10 communicates with stove hall 2, air door 8 is located at respectively greatly, reach the opposite side of little crucible between the little crucible, also establish main air door 11 on the flue 10.

Claims

1, a kind of Zinc gasifying furnace, it is characterized in that it mainly is made up of body of heater, Lu Tang, big crucible, little crucible, air door, flue, establish stove slab furnace plate in the stove hall and be the decline ladder from outside to inside, large and small crucible is arranged side by side, and big crucible is arranged near stove hall one side, and be fixed on the body of heater, the stove hall communicates with flue, and air door is located between the big or small crucible respectively, the opposite side of little crucible, and the oral area of big crucible is established crucible cover, establish the zinc fume outlet on the crucible cover, establish one between big crucible and the little crucible and connect pan pipe.
