Abstract
The utility model discloses a base of a reduction furnace, which comprises a base body, a plurality of second electroheating tubes arranged in parallel and uniformly distributed on the inner bottom surface of the base body, a metal base plate arranged below the second electroheating tubes, and a plurality of fire-resistant layers arranged between the two side walls of the base body and adjacent second electroheating tubes and between two adjacent second electroheating tubes respectively. The utility model is characterized in that each second electroheating tube is a closed-type heating tube. The structural form of the second electroheating tubes in the base of the reduction furnace is changed to prevent short-circuit failure and burning of the second electroheating tubes due to powdery materials which directly fall on the second electroheating tubes during the heating process, so as to effectively control the service life of the second electroheating tubes, improve the quality of product and reduce the production cost. Besides, the fire-resistant layers are arranged on the base to achieve a good protective effect under high-temperature and high-pressure conditions.
Description
Technical field
The utility model relates to metallurgy, chemical field, is specifically related to a kind of base that is used to produce the reduction furnace of Vanadium Pentoxide in FLAKES.
Background technology
At present, producing Vanadium Pentoxide in FLAKES is that the employing ammonium meta-vanadate is that raw material is in reduction furnace (having another name called car type furnace) and through producing after the reaction under the hot conditions.Reduction furnace comprises body of heater and base (seeing Fig. 1 and Fig. 2), is uniformly distributed with in the body of heater many first group of electrothermal tubes are installed, and base 1 plays the effect of upholder bin, and second group of electrothermal tube 2 also is installed on this base.The material frame is used for laying the raw material ammonium meta-vanadate.Usually, second group of electrothermal tube is by steel pipe and is wrapped in the outer wire spiral of steel pipe and constitutes.Because the ammonium meta-vanadate material of powder drops in the process of heating easily; And powder material is originally as electrical conductor, and dropping forms short circuit easily on second group of electrothermal tube on the base, wire spiral is often damaged; Influence products production and quality, improved production cost simultaneously.
The utility model content
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of base of reduction furnace to be provided, and it can prolong the work-ing life of second group of electrothermal tube in the life-time service process, improves the quality of products and can reduce production costs.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of base of reduction furnace; Comprise that base body, many are parallel and be located at second group of electrothermal tube on the inner bottom surface of base body in uniform way, reach the fireproofing between two adjacent second group of electrothermal tube between two side that the metal base plate and some that is located at second group of electrothermal tube below is located at the base body respectively and the adjacent second group of electrothermal tube; Wherein, every said second group of electrothermal tube is closed heat-generating pipe.
The base of above-mentioned reduction furnace, wherein, every said second group of electrothermal tube comprises high-temperature resistant tube and a wire spiral that is located in the high-temperature resistant tube.
The base of above-mentioned reduction furnace, wherein, said wire spiral is after bending to the successive wave-like, to be placed in the inner chamber of said high-temperature resistant tube.
The technical scheme of the base of the reduction furnace of the utility model; Through changing the structure formation of second group of electrothermal tube; Avoid powder material in heat-processed, directly to drop on second group of electrothermal tube and form short circuit with second group of electrothermal tube and burn; Thereby can control the work-ing life of second group of electrothermal tube effectively, improve the quality of products and reduce production costs.On base, also be provided with fireproofing in addition, under high-temperature and high-pressure conditions, have good provide protection.

Embodiment
Below through concrete embodiment and combine accompanying drawing that the technical scheme of the utility model is elaborated:
See also Fig. 3 to Fig. 5, the base of a kind of reduction furnace of the utility model comprises base body 1, many second group of electric wire tubes 2, metal base plate 4, some fireproofings 3, and wherein, base body 1 comprises the bottom surface and is connected the sidewall around the bottom surface; Many second group of electrothermal tubes 2 are parallel and be located in uniform way on the inner bottom surface of base body 1; Metal base plate 4 is located at second group of electrothermal tube 2 below, plays a protective role; Some fireproofings 3 be located at respectively between two side and the adjacent second group of electrothermal tube 2 of base body 1 and two adjacent second group of electrothermal tube 2 between, fireproofing 3 is to be processed by a kind of fire-retardant material, under high-temperature and high-pressure conditions, has the fp effect.
Every second group of electric wire tube 2 is closed heat-generating pipe, the phenomenon that forms short circuit and burn with second group of electrothermal tube to avoid powder material in heat-processed, directly to drop on second group of electrothermal tube.
In one embodiment, every second group of electric wire tube 2 is made up of high-temperature resistant tube 21 and a wire spiral 22 that is located in the high-temperature resistant tube.
In another embodiment, in order to reach best heat-transfer effect, wire spiral 22 is after bending to the successive wave-like, to be placed in the inner chamber of high temperature resistant 21 pipes, and reaching increases these wire spiral 22 length and increase and high-temperature resistant tube 21 point of contact.
The technical scheme of the base of the reduction furnace of the utility model; Through changing the structure formation of second group of electrothermal tube; Avoid powder material in heat-processed, directly to drop on second group of electrothermal tube and form short circuit with second group of electrothermal tube and burn; Thereby can control the work-ing life of second group of electrothermal tube effectively, improve the quality of products and reduce production costs.On base, also be provided with fireproofing in addition, under high-temperature and high-pressure conditions, have good provide protection.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
