Description

Atmosphere gas preheating device is squeezed into a kind of furnace

Technical field

The utility model is that atmosphere gas preheating device is squeezed into a furnace, it is accurate for be pre- hot charging for roller way kiln It sets, is mainly used in the fields such as the manufacturing of lithium ion ternary material positive electrode.

Background technique

Currently, the pre- hot charging of atmosphere gas that the production of common lithium ion ternary material positive electrode mainly passes through in the market It sets, during producing lithium ion ternary material positive electrode, wherein there is necessary process together, being exactly must be in roller way kiln Atmosphere gas is inside squeezed into, lithium ion ternary material positive electrode manufacturer currently on the market, is mostly directly to squeeze into atmosphere gas, It is directly squeezed into furnace that is atmosphere gas does not heat, then according to the production technology of roller way kiln, the temperature of atmosphere gas will be squeezed into Degree is improved by room temperature to 300 DEG C of ability meet demands, and since the temperature in kiln was high temperature originally, the atmosphere gas being driven into originally is The cold wind gas of low temperature, according to the Heat transfer law of temperature, the atmosphere gas being driven into is after the dilution of roller way kiln high temperature, kiln Interior temperature dramatic decrease, the lithium ion ternary material positive electrode that will lead to normally produce in this way are unable to satisfy high temperature firing It is required that, it is easy to there is the defects of burning substandard products, unfilled corner, color error ratio is big, so, it is unrestrained to will lead to a large amount of raw material Take, once it can only fall as garbage disposal because product quality is unqualified, moreover, also resulting in the repetition of process and labour makes With, especially for the raw material and labor cost to climb up and up both at home and abroad at present, most lithium ion ternary material anode Material manufacturing enterprise all feels more arduous.

For many disadvantages existing for above-mentioned traditional roller way kiln, lead to defect rate height, the product unfilled corner produced, color Coloured silk just, does not waste raw material, repeats recruitment, the production pressure of direct lithium ion ternary material positive electrode manufacturing enterprise is increasingly Greatly, some even all goes bankrupt or changes one's profession.

Therefore, lithium ion ternary material positive electrode manufacturer and user it is all eager look forward to have in a kind of novel furnace Squeeze into the appearance of atmosphere gas preheating device, come the qualification rate height for guaranteeing lithium ion ternary material positive electrode, the cost that saves material, The problem of greatly improving production efficiency.

Utility model content

For the defect for squeezing into atmosphere gas preheating device in above-mentioned traditional burner, this field work is engaged in the utility model accumulation for many years Experience, by studying demonstration repeatedly, eventually the generation of atmosphere gas preheating device is squeezed into a kind of furnace of the utility model.

For the above-mentioned prior art, the utility model technical problems to be solved are to say that the atmosphere gas in roller way kiln is squeezed into preparation It preheats in advance, it is larger thus to reduce burner hearth internal temperature difference caused by squeezing into because of cold wind, guarantees lithium ion ternary material anode The quality of production and qualification rate of material.

In order to solve the above technical problems, atmosphere gas preheating device is squeezed into a kind of furnace: its main feature: mainly including The horizontal right side of storage heater, the storage heater is equipped with atmosphere gas entrance, and the atmosphere gas entrance is built-in with list To valve, there is atmosphere gas outlet at the top of the storage heater by Pipe installing, and the storage heater is the accommodating of sealing Space, the main organic frame of the storage heater form, and are equipped with U-shaped heating tube, the U-shaped heating at the top of the rack Tube outside is enclosed with insulating layer, and the right side of the U-shaped heating tube connects and be equipped with air inlet, the top of the U-shaped heating tube Air outlet is connected and is equipped with, the bottom of the U-shaped heating tube is equipped with hot zone, and the U-shaped heating tube is connected with air outlet Pipeline on temperature measuring equipment is installed, the atmosphere gas outlet is two, is separately mounted to and storage heater connecting pipe Both ends, the left side hot zone You Fei of the hot zone, one end of the U-shaped heating tube are equipped with shield, the U-shaped heating tube It is five, the material of the insulating layer is alumina silicate heat-preservation cotton.

To solve the above-mentioned problems, working principle used by atmosphere gas preheating device is squeezed into a kind of furnace of the utility model It is: mainly includes storage heater, the horizontal right side of the storage heater is equipped with atmosphere gas entrance, and the atmosphere gas enters Mouth is built-in with check valve, that is to say, that and atmosphere gas can only unidirectionally be flowed into from atmosphere gas entrance, and cannot be flowed out from atmosphere gas entrance, By Pipe installing there is atmosphere gas outlet at the top of the storage heater, and (atmosphere gas outlet is two, is separately mounted to With the both ends of storage heater connecting pipe), the storage heater is the accommodating space of sealing, that is to say, that is entered from atmosphere gas The atmosphere gas that mouth is squeezed into, after Hot-blast Heating gas heats in advance, using the atmosphere gas outlet stream at the top of fan heater heater Out, the main organic frame of the storage heater forms, and is equipped with U-shaped heating tube (the U-shaped heating tube at the top of the rack It is five), the U-shaped heating tube outside is enclosed with insulating layer (material of the insulating layer is alumina silicate heat-preservation cotton), the U The right side of type heating tube connects and is equipped with air inlet, and the top of the U-shaped heating tube connects and be equipped with air outlet, the U The bottom of type heating tube is equipped with hot zone, is equipped with temperature measuring equipment on the pipeline that the U-shaped heating tube is connected with air outlet, surveys Warm device can according to demand, the temperature of appropriate adjustment atmosphere gas, the left side hot zone You Fei of the hot zone.

The major advantage that atmosphere gas preheating device is squeezed into a kind of furnace is:

1, the qualification rate of lithium ion ternary material positive electrode is high, greatly improves the competitive advantage of producer.

2, save material cost, improves the profit margin of producer, but also free from environmental pollution.
