Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat treatment kilns, and in particular relates to a replacement chamber. Background Art
[0002] Lithium battery positive electrode materials must be roasted in a high-temperature kiln, and the positive electrode materials of lithium batteries must be loaded in a sagger during the sintering process. The large-scale production of reaction product water-containing materials such as high-nickel materials and lithium iron phosphate materials is produced through high-temperature solid-phase synthesis. During the high-temperature sintering process, these materials will produce a large amount of water vapor, which usually contains electrolytes such as Cl and OH, which will cause serious corrosion to the steel structure of the furnace body. Therefore, these water vapors need to be discharged from the furnace through the exhaust system of the roller kiln in time.
[0003] The sintering process of the above materials requires a special atmosphere concentration. Therefore, a displacement chamber is provided at the end of the roller kiln. The displacement chamber is connected and disconnected with the outside and the internal space of the roller kiln by opening and closing the gate. When the gate of the displacement chamber is opened, the internal space of the kiln will be connected with the displacement chamber. Since the temperature in the furnace is high and the temperature in the displacement chamber is low, the higher temperature gas will quickly diffuse into the displacement chamber. At this time, due to the low temperature in the displacement chamber, the water vapor (water vapor with electrolyte) in the gas in the furnace will condense into water droplets on the top cover of the displacement chamber. The top cover of the existing displacement chamber adopts a flat top structure. The water droplets gathered on the top cover will randomly drip downwards and may fall into the sagger, which is easy to affect the quality of the material.

[0027] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings.
[0028] Embodiment 1:
[0029] Reference Figure 1 to Figure 3As shown, the displacement chamber in this embodiment includes a body 1 and a top cover 2 arranged on the body 1, and the top cover 2 includes a first cover plate 21 and a second cover plate 22, at least one of the first cover plate 21 and the second cover plate 22 is inclined, and the spacing between the first cover plate 21 and the second cover plate 22 gradually increases along the whole or part from top to bottom, and the orthographic projections of the first cover plate 21 and the second cover plate 22 in the vertical direction are both located within the orthographic projection of the body 1 in the vertical direction. According to this design, during the sintering process, water vapor gathers on the inner wall of the top cover 2 and condenses into water droplets on the inner wall of the top cover 2. Under the influence of its own weight, the water droplets can slide down to the connection between the top cover 2 and the body 1 and then slide down along the side wall of the body 1, reducing the possibility of falling into the sagger, avoiding the contact between the water droplets and the material, and preventing the water droplets from having an adverse effect on the material in the sagger.
[0030] In order to facilitate the movement of the sagger in the displacement chamber and keep the atmosphere during the sintering process unchanged, the main body 1 in this embodiment includes a bottom plate 11 and two side plates 12 relatively arranged on the bottom plate 11, and the two sides of the top cover 2 are respectively connected to the two side plates 12, and the displacement chamber is formed with a first opening and a second opening relatively arranged, and a first valve and a second valve are movably arranged in the displacement chamber, and the first valve and the second valve are used to control the opening and closing of the first opening and the second opening respectively. Among them, the main body 1, the top cover 2, the first valve and the second valve are enclosed to form a receiving chamber, and the opening and closing of the receiving chamber are controlled by the first valve and the second valve. When the receiving chamber needs to be connected to the outside world, the first valve or the second valve is raised; when the receiving chamber needs to be disconnected, the first valve and the second valve are lowered.
[0031] In order to facilitate the water droplets condensed on the entire first cover plate 21 and the second cover plate 22 to slide down along the inclined direction of the top cover 2 instead of falling directly from the top cover 2, the top cover 2 in this embodiment includes a symmetrically distributed first cover plate 21 and a second cover plate 22, and the first cover plate 21 and the second cover plate 22 are both inclined.
[0032] Specifically, in this embodiment, the first side of the first cover plate 21 adjacent to the body 1 and the first side of the second cover plate 22 adjacent to the body 1 are directly connected to the body 1 respectively, and the second side of the first cover plate 21 away from the body 1 and the second side of the second cover plate 22 away from the body 1 are directly connected. According to this design, the gathered water vapor can form water droplets on the first cover plate 21 or the second cover plate 22 and flow to the side plate 12 along the inclination direction thereof, and then flow to the bottom plate 11 along the side plate 12.
[0033] In the use state, it is necessary to fill other gases into the displacement chamber so as to exhaust all the air. The flat roof structure of the existing displacement chamber is not conducive to gas discharge, and it is necessary to set an additional suction structure on the top cover 2 to improve the efficiency of air discharge. Since the top cover 2 of the displacement chamber in the present embodiment has an inclined first cover plate 21 and a second cover plate 22, the air can be gathered toward the top of the top cover 2 under the push of other gases. Therefore, the displacement chamber in the present embodiment also includes an exhaust pipe 3, part of the exhaust pipe 3 is arranged on the first cover plate 21, and the other part of the exhaust pipe 3 is arranged on the second cover plate 22, and the exhaust pipe 3 is connected to the receiving chamber. According to this design, there is no need to set an additional suction device to completely discharge the air collected at the top. Of course, when the gas in the receiving chamber is other gases, other gases can also be discharged from the receiving chamber by discharging air.
[0034] In this embodiment, the first cover plate 21 and the second cover plate 22 are both planes. Of course, the present application is not limited thereto, and one of the first cover plate 21 and the second cover plate 22 is a plane and the other is a curved surface; or one of the first cover plate 21 and the second cover plate 22 is a plane and the other is a combination of a plane and a curved surface; or one of the first cover plate 21 and the second cover plate 22 is a curved surface and the other is a combination of a plane and a curved surface; all of which can make the water droplets gathered on them slide down along the inclined direction instead of falling directly.
[0035] In this embodiment, both the first cover plate 21 and the second cover plate 22 are provided with inspection ports, and the inspection ports are covered with inspection covers 4. In this embodiment, the inspection covers 4 are provided with handles 5. When a problem occurs during the sintering process, the inspection ports can be opened to inspect the equipment to facilitate troubleshooting.
[0036] Embodiment 2:
[0037] The body 1 of the displacement chamber in this embodiment is completely the same as the body 1 of the displacement chamber in the first embodiment, except that the structure of the top cover 2 is different.
[0038] Specifically, refer to Figure 4 As shown, the top cover 2 in this embodiment includes a first cover plate 21 , a second cover plate 22 , and a connecting plate 23 . The first cover plate 21 adjacent to the second side of the body 1 and the second cover plate 22 adjacent to the second side of the body 1 are connected via the connecting plate 23 .
[0039] In order to facilitate the exhaust of air or other gases from the receiving cavity, the displacement chamber in this embodiment further includes an exhaust pipe 3, which is arranged on the connecting plate 23 and communicates with the receiving cavity. Since the connecting plate 23 is arranged horizontally, the exhaust pipe 3 can be easily installed.
[0040] It can be seen from the above technical solutions that the utility model has the following beneficial effects:
[0041] The utility model provides a displacement chamber, which can make the water drops gathered on the cover plate slide down to the inner wall of the main body along the inclined direction of the cover plate by arranging an inclined cover plate, thereby reducing the possibility of the gathered water drops directly falling from the cover plate into the sagger, avoiding the contact between the water drops and the material, and preventing the water drops from having a bad influence on the material in the sagger.
[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
