In the related technology, the tunnel kiln is used for carbonization in the current production process of the graphite anode material, and the method has the advantages of low consumption, high productivity, low cost and the like. However, the tunnel kiln needs to be matched with a crucible, the crucible comprises a crucible body 100 and a crucible cover, the crucible body and the crucible cover are movably matched, and a gap is needed to exist so as to balance the internal and external air pressure; however, in the high-temperature carbonization process, natural gas and air are mixed and combusted for heating, so that the oxygen content in the kiln is high. Particularly, in the cooling process, the furnace body shows negative pressure, the tightness between the crucible and the crucible cover is poor, oxygen in the furnace body is sucked into the crucible, and the situation that materials in the crucible are oxidized exists.

Referring to fig. 1 and 6, a crucible of the present disclosure includes: a crucible body 100 having an open end 300, and an air passage formed in the crucible body 100; the oxygen removing part is detachably installed at the open end 300, and has a microporous structure, the microporous structure forms the air passage for gas to enter and exit, and the oxygen removing part is used for blocking oxygen from entering the crucible body 100 and/or reducing and absorbing and/or adsorbing oxygen in the gas.

Since the deoxidizing part is provided with a plurality of micropores which are communicated and not communicated with each other, namely, the micropores form a micropore structure of the deoxidizing part; in actual work, the micropores can supply gas to enter and exit, so that the contact area between the deoxidizing part and the gas can be effectively increased; specifically, the microporous structure may be formed by natural stacking, or the oxygen removing portion itself may be formed by puncturing with a needle-like tool or the like at a later stage by man, and the like, and the specific limitation is not required.

Wherein, a containing cavity for containing materials is formed between the deoxidizing part and the crucible body 100, the deoxidizing part is detachably arranged at the open end 300, so as to be convenient for taking and placing materials, for example, when the deoxidizing part is separated from the open end 300, the crucible body 100 can be filled with materials or the carbonized materials can be taken out; after the material is filled, the deoxidizing part can be arranged at the opening end 300 to close the opening end 300, so that the material is prevented from directly contacting with the outside air; the oxygen-removing part itself may be made of its physical properties to adsorb oxygen near the oxygen-removing part or entering the microporous structure, or its chemical properties to reduce and absorb oxygen near the oxygen-removing part or entering the microporous structure, or the oxygen-removing part may be made of a material having both chemical properties capable of reacting with oxygen and physical properties capable of adsorbing oxygen, that is, the choice of the material for the oxygen-removing part is not particularly limited as long as it can perform the oxygen-removing function, but the choice of the material for the oxygen-removing part is not difficult for those skilled in the art and is common knowledge of those skilled in the art.

It should be noted that, the micropore structure on the deoxidizing part is used to construct the air passage for gas to enter and exit, so that the gas can be dispersed and enter and exit effectively; that is, no dead angle exists; in addition, because the pore diameter of the micropore structure is very small and is similar to a capillary, and the micropores do not extend along a straight line, the shape of the micropore is in a curved shape, so that the flow resistance of gas along the micropore structure is very large, and at high temperature, the material is sintered, meanwhile, micro positive pressure is formed in the crucible body 100, volatile matters in the crucible body 100 can volatilize out through the micropore structure, and the safety problem caused by too large air pressure in the crucible body 100 is reduced.

When the crucible provided by the utility model is applied, the deoxidizing part is detachably arranged at the opening end 300 of the crucible body 100 by improving the crucible, and the micropore structure on the deoxidizing part can ensure that the interior of the crucible body 100 can be communicated with the outside so as to balance the internal and external air pressure of the crucible body 100 when materials are sintered; the microporous structure can be used for forming an air passage so as to increase the contact area between the gas entering and exiting the crucible body 100 and the deoxidizing part, and the deoxidizing efficiency and the deoxidizing amount can be improved; and, because the pore diameter of the micropore structure is very small, the flow resistance of the micropores can be increased to prevent oxygen from entering the crucible body 100, that is, the flow resistance of the micropores is poor, when the flow resistance is greater than the air pressure difference between the outside and the inside of the crucible body 100, the oxygen can be blocked outside the crucible body 100, and the condition that the oxygen contacts the material to cause the oxidation of the material can be reduced.

As shown in fig. 6, on the basis of the above embodiment, the oxygen removing portion includes: an oxygen scavenger layer 600; the open end 300 has a filter cavity for accommodating the oxygen scavenger layer 600, and gaps are formed in the oxygen scavenger layer 600, and the gaps form a microporous structure.

The deoxidizer layer 600 is formed by the existing granular deoxidizer, specifically, the granular deoxidizer can be filled in the filter cavity of the opening end 300, so that the granular deoxidizer has gaps, and the gaps are in three-dimensional net-shaped staggered communication, namely, a microporous structure; wherein, the size of the gap determines the aperture of the micropore structure, and the gap size can be changed by controlling the filling density in the concrete implementation; the gap size can also be varied by varying the degree of compaction.

In addition, it should be noted that the thickness of the oxygen scavenger layer 600 needs to be controlled, so that the oxygen scavenger layer 600 is prevented from being too small in thickness, which results in smaller oxygen flow resistance and poor oxygen removal effect, and the thickness of the oxygen scavenger layer 600 cannot be too large, which results in serious invasion of the oxygen scavenger layer 600 into the storage space in the crucible body 100, resulting in less single treatment capacity of the crucible body 100 and affecting the production efficiency. In specific implementation, the thickness of the deoxidizer layer can be set to be between 1/20 and 1/8 of the height of the interior of the crucible body 100, so that the reduction of oxygen flow resistance and poor oxygen removal effect caused by the too small thickness of the deoxidizer layer can be reduced, and the serious invasion of the deoxidizer layer 600 into the storage space in the crucible body 100 caused by the too large thickness of the deoxidizer layer can be reduced, so that the single treatment capacity of the crucible body 100 is reduced, and the production efficiency is influenced. The filter chamber is disposed at the open end 300, so that the gas flowing into and out of the crucible body 100 must flow through the filter chamber, thereby ensuring that the gas must flow through the oxygen scavenger layer 600 in the filter chamber.

On the basis of the above embodiment, as shown in fig. 2 to 4, the oxygen removing portion further includes: a first crucible cover 400 covering the open end 300; a second crucible cover 500 disposed in the crucible body 100; wherein the regions between the first crucible cover 400, the second crucible cover 500 and the crucible body 100 constitute a filter chamber.

The open end 300 is covered with the first crucible cover 400 to form a first sealing structure, that is, gas can only enter and exit the crucible body 100 through the gap between the first crucible cover 400 and the open end 300; in addition, the second crucible cover 500 is arranged in the crucible body 100 so as to keep the second crucible cover 500 and the first crucible cover 400 parallel, the second crucible cover 500 is in clearance fit with the inner wall of the crucible body 100, and the clearance size between the second crucible cover 500 and the inner wall of the crucible body 100 is smaller than the particle size of the granular deoxidizer, so that the situation that the deoxidizer falls into materials is reduced; at this time, the region between the first crucible cover 400, the second crucible cover 500 and the crucible body 100 may be formed as a filter cavity, and the oxygen scavenger layer 600 may be formed by filling the filter cavity with the oxygen scavenger; wherein the oxygen scavenger layer 600 forms a second sealing structure, and the second crucible cover 500 and the inner wall of the crucible body 100 form a third sealing structure in a clearance fit.

Obviously, in general, the crucible body is vertically placed, and then the deoxidizer filled between the first crucible cover 400 and the second crucible cover 500 is pressed down by the first crucible cover 400, so that the density of the deoxidizer layer is kept stable, and when the crucible body 100 is positive pressure, the deoxidizer layer 600 is caused to be loose by the upward impact of air pressure on the deoxidizer layer 600, the pore diameter of the micropore structure is enlarged, and the deoxidizing effect of the deoxidizer layer and the flow resistance of the micropore structure are reduced.

Specifically, the second crucible cover 500 may be placed on the material to be supported by the material; or by other structural supports, such as providing protrusions on the inner wall of the crucible body 100 to support the second crucible cover 500; when positive pressure is applied in the crucible body 100, the air pressure will push the second crucible cover 500 upwards, and the weight of the second crucible cover 500 will counteract the total positive pressure impulse force due to the smaller positive pressure under normal conditions, so as to avoid extrusion of the oxygen scavenger layer.

As shown in fig. 1, on the basis of the above embodiment, the apparatus further includes a first limiting mechanism disposed in the crucible body 100, where the first limiting mechanism is connected with the second crucible cover 500 and is used to limit the depth direction of the second crucible cover 500 in the crucible body 100, so as to adjust the volume of the filter cavity, and corresponds to adjusting the thickness of the oxygen scavenger layer 600.

The first limiting mechanism can be arranged in the crucible body 100 and is beneficial to limiting the depth of the second crucible cover 500 in the crucible body 100 by the first limiting mechanism so as to control the thickness of the deoxidizer layer; specifically, the upper end of the first limiting mechanism and the lower end of the second crucible cover 500 can be contacted to limit; or the second crucible cover 500 is detachably connected to the crucible body 100 through a first limiting mechanism, for example, the second crucible cover 500 is detachably connected to the crucible body 100 through a screw structure.

As shown in fig. 1, on the basis of the above embodiment, the first limiting mechanism includes: a retainer ring 200 provided in the crucible body 100, one end of the retainer ring 200 facing the first crucible cover 400 being in surface contact with the second crucible cover 500; wherein, the outer wall of the retainer ring 200 is in sealing connection with the inner wall of the crucible body 100, and the second crucible cover 500 is used for closing the inner hole of the retainer ring 200.

The cross section of the inner cavity of the crucible body 100 and the second crucible cover 500 can be both circular, and likewise, the retainer ring 200 can be provided with a circular ring structure, and when in installation, the retainer ring 200 and the crucible body 100 can be coaxially arranged; and the diameter of the inner hole of the retainer ring 200 can be set smaller than the diameter of the second crucible cover 500, the second crucible cover 500 arranged on the retainer ring can be limited; and because the second crucible cover 500 is in clearance fit with the inner wall of the crucible body 100, the downward end of the second crucible cover 500 contacts the upward end surface of the retainer ring 200, so that the opening range of the inner hole of the retainer ring 200 can be covered to close the inner hole of the retainer ring 200, and therefore, the gas can only flow through the contact clearance between the second crucible cover 500 and the retainer ring 200.

On the other hand, since the oxygen scavenger layer 600 vertically acts on the upper end of the second crucible cover 500, it is pressed by the oxygen scavenger layer 600, so that the sealability between the second crucible cover 500 and the retainer ring 200 can be improved, and the oxygen scavenger can be reduced from falling into the crucible body 100.

Specifically, the cross section of the retainer ring 200 may be square, or may be in the shape of an inverted right trapezoid, or may be in the shape of an inverted right triangle, which is not particularly limited herein; it should be noted that, the crucible is configured as an inverted right trapezoid or an inverted right triangle, which is beneficial to pouring the materials in the crucible body 100.

As shown in fig. 2, 3 and 4, on the basis of the above embodiments, the first crucible cover 400 and the second crucible cover 500 are respectively provided with a second limit mechanism and a third limit mechanism for limiting the radial displacement of the crucible body.

The first limiting mechanism can be arranged on the first crucible cover 400 to limit the radial movement of the first crucible cover, so that the situation that collision displacement is received in the sintering process is reduced, or the operator is not covered accurately, and the tightness of the first crucible cover is finally affected.

Likewise, by providing the second limiting mechanism on the second crucible cover 500 to limit the radial movement of the second crucible cover 500 in the crucible body 100, the problem that the second crucible cover 500 is displaced to cause sealing failure when the outer diameter of the second crucible cover 500 and the inner diameter of the inner hole of the retainer ring 200 are not greatly different is solved; it should be noted that, in order to facilitate the taking and placing of the second crucible cover 500 in the crucible body 100, the outer diameter of the crucible body 100 may be reduced, which may also result in a small difference between the outer diameter of the second crucible cover 500 and the inner diameter of the retainer ring 200.

It should be noted that, since the retainer ring 200 is coaxially disposed in the crucible body 100, a reinforcing rib may be formed to improve the structural strength of the crucible body 100; if the structural strength requirement on the crucible body 100 is exceeded after the retainer ring 200 is arranged, the side wall of the crucible body 100 can be thinned after the retainer ring 200 is arranged, so that the weight of the crucible body 100 can be reduced, and the crucible body is convenient to take and place; and the volume of the single crucible body 100 can be effectively increased, the heat conduction speed is improved, and the production efficiency is effectively improved; in a specific production, the retainer ring 200 and the crucible body 100 may be integrally provided.

For example, the outer side wall of the crucible body 100 may be coated with a heat-resistant and heat-conductive coating to match with the inner wall of the light and thin crucible body 100, and the heat-resistant and heat-conductive coating may be silicate, so that the service life of the heat-resistant and heat-conductive coating can be effectively prolonged.

On the basis of the above embodiment, the second limiting mechanism includes a first protrusion 410 for inserting into the open end 300 and provided to the first crucible cover 400; and the third stopper mechanism includes a second protrusion 510 for inserting into the inner hole of the retainer ring 200 and provided to the second crucible cover 500.

The first protrusion 410 and the second protrusion 510 may be respectively configured as a cylinder, specifically, the first protrusion 410 is coaxially fixed at one end of the first crucible cover 400 facing downward, and when the first protrusion 410 is installed, the first protrusion 410 is inserted into the open end 300, and the first protrusion 410 and the open end 300 are in clearance fit, so that the first crucible cover 400 can be limited to move radially by the first protrusion 410; and, the first protrusion 410 and the first crucible cover 400 may be integrally disposed, and the gas circulation gap may be reduced by using the first protrusion 410 in cooperation with the open end 300, thereby further enhancing the sealing property.

Similarly, the second protrusion 510 is coaxially fixed to the downward end of the second crucible cover 500, and the second protrusion 510 is inserted into the inner hole of the retainer ring 200, and the second protrusion 510 and the inner hole of the retainer ring 200 are in clearance fit, so that the radial movement of the second crucible cover 500 can be limited, and the second protrusion 510 and the second crucible cover 500 are integrally arranged, so that the gas flow gap is reduced, and the tightness can be enhanced.

As shown in fig. 5, a handle is disposed at one end of the second crucible cover 500 facing the open end 300, so as to be held by an operator, thereby facilitating the taking and placing of the second crucible cover 500; preferably, the handle may be a third protrusion 520 disposed at the upper end of the second crucible cover 500, or may be other structures, which are not specifically limited herein and are all within the scope of the present application.

Based on the above embodiments, oxygen scavenger layer 600 includes at least one of Jiao Dingceng, calcined coke layer, semi-coke layer, coal layer, and graphite layer.

That is, the deoxidizer layer 600 is formed by filling deoxidizer, if the deoxidizer is a diced coke, the deoxidizer layer is a diced coke layer; if the deoxidizer is calcined coke, the deoxidizer layer is a calcined coke layer; if the deoxidizer is semi-coke, the deoxidizer layer 600 is semi-coke layer; if the deoxidizer is coal, the deoxidizer layer 600 is a coal seam, and so on; it should be noted that the oxygen scavenger is not limited to the above, and other oxygen scavengers can be used to achieve the same effects.

In particular, the above-mentioned multiple deoxidizers may be mixed and used, and are not limited to a single deoxidizer.

On the basis of the above embodiment, the crucible body 100, the first crucible cover 400 and the second crucible cover 500 are all made of silicon carbide, wherein the retainer ring 200 and the crucible body 100 are integrally fired.
