Description

Atmosphere stove of grease proofing cigarette explodes stove

Technical Field

The utility model relates to a heat treatment equipment field especially relates to an atmosphere stove of fried stove of grease proofing cigarette.

Background

The tunnel boring machine is one of major core equipment which can measure the manufacturing level and the capability of national equipment, has the advantages of high mechanization degree, high construction speed, high safety and the like, and is widely applied to shield construction of important projects such as domestic subways, tunnels, water diversion, urban pipe networks and the like. The shield cutter is directly contacted with a tunneling rock stratum, needs to bear high pressure and impact, is a vulnerable and easily-damaged part in the tunneling process, and in recent years, the shield localization process of China makes a great breakthrough, a plurality of key (parts) are subjected to heat treatment in China, and the raw materials are high-carbon high-alloy steel, and the heat treatment process is generally vacuum furnace oil quenching treatment.

With the increasing requirement of environmental protection, the less or no oxidation heat treatment becomes the first choice for the heat treatment process of tools and dies and various steel parts, the less or no oxidation treatment mode becomes necessary for key parts of the cutter due to the characteristics of raw materials, and the tempering protection also becomes the trend of product production. Quenching oil is generally selected as a quenching medium for heat treatment of the cutter, in order to prevent cracking of the tool and die steel after quenching, the temperature of the quenching medium is generally about 300 ℃, deoiling and cleaning are difficult to realize after discharging, and the quenching medium can directly enter a tempering furnace for tempering. During the tempering process, a large amount of oil smoke is generated along with the rise of the temperature, if the oil smoke is not exhausted out of the resistance furnace in time, the oil smoke is accumulated in a hearth and carbonized at high temperature to form a conductive short circuit, so that equipment failure is caused, and the large amount of oil smoke is easy to rapidly expand at high temperature to generate explosion, so that safety accidents are caused.

The sealing structure adopted under the protective atmosphere condition of the tempering furnace, the internal protective gas environment and the risk of explosion easily result. At present, the problem of frying the furnace is solved by a mode of increasing circulating air on the existing structure of an atmosphere protection tempering furnace, the effect at the initial stage of use can be achieved, but the problem of frying the furnace still sometimes happens and cannot be effectively solved as time is prolonged, and therefore potential safety hazards exist.

As shown in fig. 1, the atmosphere furnace of the oil-smoke preventing fryer of the present embodiment includes: shell 1, intake stack 2, insulating layer 3, fan 4, air ducting 5, air-out pipeline 6 and air exhauster 7, insulating layer 3 is located in the shell 1, air ducting 5 is located in the insulating layer 3, fan 4 locates the upper portion of shell 1 and runs through shell 1, intake stack 2 runs through shell 1, extend to fan 4's below behind insulating layer 3 and the air ducting 5, air ducting 5 below is equipped with air-out pipeline 6, air-out pipeline 6 is connected to the below of air exhauster 7.

In this embodiment, the air inlet pipe 2 is connected to an external blower, and supplies air into the atmosphere furnace through the blower and the air inlet pipe 2, and then blows the air with the soot to the bottom of the atmosphere furnace through the fan 4 and the air guide device 5, and the soot is drawn out through the air outlet pipe 6 by an exhaust fan at the bottom of the atmosphere furnace.

In the atmosphere stove of the fried stove of grease proofing cigarette of this embodiment, intake stack 2, air ducting 5 and air-out pipeline 6 all have two, and the symmetry sets up to the wind-force that makes to get into in the atmosphere stove is bigger, and the oil smoke gets rid of the effect better.

In the atmosphere stove of the fried stove of grease proofing cigarette of this embodiment, be equipped with opening size adjustable rotary valve on the intake stack 2, thereby the adjustment rotary valve controls intake of intake stack 2, guarantees that the oil smoke of oil smoke emission early stage discharges fast, and the slow emission of later stage balances the stove atmosphere and reduces gas loss.

In the atmosphere furnace of the oil smoke explosion-proof furnace of the embodiment, the inner diameter of the air inlet pipeline 2 is more than 100mm, and the air inlet efficiency can be higher by the air inlet pipeline 2 with a large diameter.

In the atmosphere stove of grease proofing cigarette fried stove of this embodiment, insulating layer 3 is piled up through heat-resisting light brick and builds, and heat-resisting light brick will completely cut off the oil smoke and enter into shell 1, stops because the cotton absorption flue gas of heat preservation leads to the problem of burning.

In the atmosphere stove of grease proofing oil smoke fried stove of this embodiment, heat-resisting light brick's total thickness is more than 280mm, gives off through the better isolated heat of thicker heat-resisting light brick, guarantees that the outside temperature rise of atmosphere stove is not higher than 45 ℃, avoids causing great influence to the staff.

The working principle of the embodiment is as follows: open the intake stack 2 and the fan 4 of atmosphere stove top lateral wall during the oil smoke prevention, protective gas enters into fan 4 below from intake stack 2, and fan 4 rotary work blows in gas air ducting 5, then discharges from the air-out pipeline 6 of air ducting 5 bottom, and exhaust fan 7 makes the oil smoke higher from the elimination efficiency of air-out pipeline 6. Because the fan 4 and the air guide device 5 are used for guiding the flow in the left and right directions, the oil fume gas enters the bottom and forms a gas circulation line with the air outlet pipeline 6 at the bottom, the oil fume in the furnace can be rapidly pumped away through the exhaust fan 7, the heat-insulating layer 3 of the heat-resistant light brick body structure can insulate heat, the furnace body structure is protected, the combustion condition of the atmosphere furnace body is prevented, and the oil fume exhaust valve adopts a rotary valve with an adjustable opening, so that the change of the air draft flow speed along with the change of the oil fume amount is ensured.

The atmosphere stove of the fried stove of grease proofing cigarette of this embodiment prevents inside temperature loss through the insulating layer, ensures that furnace body ambient temperature can not too high influence staff, prevents simultaneously that the oil smoke from producing the burning, and protective gas blows the oil smoke to atmosphere bottom of the furnace portion through fan and air ducting in from the intake stack atmosphere stove, and the oil smoke combines the air exhauster to discharge by the exhaust duct of atmosphere bottom of the furnace portion to in time arrange the oil smoke in the atmosphere stove to the greatest extent, prevent that the oil smoke inflation leads to the atmosphere stove to fry the stove.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
