Description

Technical Field

[0001] This utility model relates to the field of lithium carbonate production technology, and in particular to a lithium mica briquette structure. Background Technology

[0002] With the adjustment of China's energy structure and the vigorous development of new energy technologies, the new energy vehicle industry has developed rapidly, leading to a surge in demand for lithium batteries. As one of the key raw materials for lithium battery manufacturing, the demand for lithium carbonate has increased significantly. In the field of lithium carbonate production, tunnel kilns, as key thermal equipment, are facing increasingly prominent issues regarding energy consumption and emissions. Traditional lithium mica pressed block brick structures, using a regular layered arrangement, can meet basic firing requirements, but have significant thermal defects.

[0003] Specifically, in existing technologies, excessively high brick density leads to narrow airflow channels within the kiln, increasing resistance to flue gas exhaust and forcing the exhaust fan to operate at higher frequencies to maintain stable kiln pressure. This process not only increases power consumption but also results in heat loss due to excessively high flue gas velocity, reducing the effective heat exchange rate within the kiln. Simultaneously, uneven stacking creates localized temperature gradients, leading to uneven heating of the lepidolite ore and insufficient reaction completion, directly reducing the lithium extraction conversion rate. Furthermore, unstable negative pressure within the kiln caused by resistance fluctuations further exacerbates heat loss, creating a vicious cycle. Existing brick stacking structures, in pursuing filling efficiency, neglect thermodynamic optimization requirements, becoming a key bottleneck restricting the improvement of tunnel kiln energy efficiency.

[0018] Preferably, the first brick structure has no more than nine layers, and the second brick structure has no more than nine layers.

[0019] Preferably, the ratio of the size of the inter-row fire channel, the size of the inter-row fire channel, and the length of the first brick is 2:1:2.

[0021] Preferably, the number of brick stack structures is six, and the six brick stack structures are arranged in a matrix distribution of two vertical columns multiplied by three horizontal rows.

Thus, a feature defined as "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0031] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is in conjunction with the appendix Figures 1 to 3 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0033] A lithium mica briquette brick structure includes several brick stack structures 100, which are arranged in a matrix of M columns and N rows. There is a column fire channel 21 between two adjacent columns of brick stack structures 100 and a row fire channel 22 between two adjacent rows of brick stack structures 100.

[0034] The brick stack structure 100 includes several rows of brick row structures 110, and a brick row gap 23 is provided between two adjacent rows of brick row structures 110.

[0035] The brick row structure 110 includes several layers of brick structure 111, which are stacked from bottom to top. Each brick structure 111 includes several bricks 00, which are arranged at intervals along the longitudinal direction. There is a brick gap 24 between adjacent bricks 00 along the longitudinal direction. The brick gaps 24 between adjacent brick structures are staggered in the vertical direction.

[0036] Matrix distribution refers to the spatial arrangement of several brick stack structures 100 on the kiln car 9. Specifically, it can be achieved using an orthogonal arrangement with equal spacing, balancing the airflow distribution through the geometric symmetry of M columns and N rows. Inter-row fire channels 21 refer to longitudinal ventilation channels penetrating the kiln body, specifically formed by controlling the spacing between adjacent (left and right) brick stack structures 100, used to establish the axial flow path of flue gas. Inter-row fire channels 22 refer to transverse ventilation channels penetrating the kiln body, specifically formed by adjusting the spacing between front and rear brick stack structures 100, used to promote the radial diffusion of flue gas. Inter-row fire channels 21 and inter-row fire channels 22 constitute the main airflow channel. Brick row gaps 23 refer to the guiding space between adjacent brick row structures 110 within the same brick stack structure 100, used to construct an auxiliary airflow channel network. The staggered setting of the brick gap 24 refers to the axial offset layout of the gap 24 between adjacent bricks. Specifically, it can be achieved by staggered arrangement of half brick lengths to form a multi-level turbulent mixing area. At the same time, it allows more area of ​​the brick 00 (lithium mica sheet) to be "exposed" on the upper and lower surfaces of the stacked contact, thereby increasing the heat-receiving area.

[0037] A multi-dimensional, three-dimensional ventilation network is formed by a matrix distribution of several brick stack structures 100. The inter-row fire channels 21 and inter-row fire channels 22 constitute the main airflow channels, effectively reducing flue gas flow resistance. Inside the brick stack structure 100, multiple rows of brick structures 110, combined with brick row gaps 23, form secondary airflow channels. Through a composite gap layout of longitudinal rows and transverse layers, gas flow optimization in three-dimensional space is achieved. The brick layer structure 111 uses longitudinally spaced bricks 00 to form staggered brick gaps 24. While ensuring structural stability, the staggered gaps 24 between upper and lower layers create a turbulent effect, promoting uniform heat distribution. The overall structure forms a gradient ventilation system through a hierarchical gap design, reducing smoke exhaust energy consumption and improving heat exchange efficiency. Simultaneously, the three-dimensional, staggered gap layout avoids the localized high-temperature accumulation phenomenon of traditional layered structures, ensuring uniform heating of the lithium mica ore.

[0038] Through the above technical solutions, this utility model effectively reduces the flow resistance of flue gas in the kiln and reduces the energy consumption of the exhaust fan; it enhances the contact area between the high-temperature airflow and the brick 00 (lithium mica sheet), thereby improving the heat transfer efficiency; it balances the temperature distribution in the kiln through a three-dimensional ventilation network, thereby improving the uniformity of the ore being heated; the turbulence effect formed by the staggered gap layout promotes heat diffusion and avoids local high temperature accumulation; and the multi-level guide channel design optimizes the airflow path and stabilizes the negative pressure environment in the kiln.

[0039] Furthermore, the brick layer structure 111 includes several layers of first brick layer structure 1111 and several layers of second brick layer structure 1112, which are staggered and stacked from bottom to top.

[0040] The brick 00 includes a first brick 01, a second brick 02, and a third brick 03;

[0041] The first brick layer structure 1111 includes a first brick 01, a third brick 03 and several second bricks 02. The first brick 01 is located on the front side of the first brick layer structure 1111, the third brick 03 is located on the rear side of the first brick layer structure 1111, and several second bricks 02 are spaced apart between the first brick 01 and the third brick 03.

[0042] The second brick layer structure includes a first brick 01, a third brick 03, and several second bricks 02. The third brick 03 is located on the front side of the second brick layer structure 1112, the first brick 01 is located on the rear side of the second brick layer structure 1112, and several second bricks 02 are spaced apart between the first brick 01 and the third brick 03.

[0043] The front wall surfaces of the first brick 01 of the first brick layer structure 1111 and the third brick 03 of the adjacent second brick layer structure 1112 are vertically aligned, and the rear wall surfaces of the third brick 03 of the first brick layer structure 1111 and the first brick 01 of the adjacent second brick layer structure 1112 are vertically aligned.

[0044] The design of alternating brick layer structures 111 breaks away from the rigid layout of traditional regular stacked arrangements. The first brick layer structure 1111 and the second brick layer structure 1112 adopt an alternating form where the front and rear bricks 00 are interchanged, creating a spatially complementary relationship between the front and rear bricks 00 of adjacent brick layer structures 111. This ensures the proper setting of the brick gaps 24, resulting in a staggered distribution of the brick gaps 24 between adjacent layers. When the front walls of the first brick 01 of the first brick layer structure 1111 and the third brick 03 of the second brick layer structure 1112 are vertically aligned, the front side of the brick row structure 110 forms a continuous support surface, while the second bricks 02 in the middle area are spaced apart to create transverse channels (brick gaps). This alternating layout forces the flue gas to bypass the gaps between different layers during longitudinal flow, extending the heat exchange time. Simultaneously, the staggered setting of the brick gaps 24 between upper and lower layers prevents direct airflow penetration, forcing the flue gas to form vortices inside the brick stack structure 100, increasing the contact area with the brick 00 surface. The alignment of the third brick 03 with the first brick 01 on the rear side maintains the rear support strength of the brick stack structure 100 and prevents structural deformation caused by thermal expansion.

[0045] By arranging bricks of different sizes in zones, the tortuousness of the flue gas diffusion path is increased and the heat exchange time is extended while ensuring structural strength; the heating area of ​​bricks is increased, avoiding the blockage of the heating area of ​​bricks caused by the tight stacking of bricks in traditional brick stacking structures; and local airflow dead zones are avoided.

[0046] Furthermore, the first brick layer structure 1111 and the second brick layer structure 1112 each include seven second bricks 02.

[0047] The first brick layer structure 1111 refers to a layered arrangement consisting of a first brick 01, a third brick 03, and a second brick 02 in the middle. Specifically, it is implemented by placing the first brick 01 at the front and the third brick 03 at the back, with the second brick 02 in the middle to form a gap. The second brick layer structure 1112 refers to a layered arrangement consisting of a third brick 03, a first brick 01, and a second brick 02 in the middle. Specifically, it is implemented by placing the third brick 03 at the front and the first brick 01 at the back, with the second brick 02 in the middle to form a gap. The 7 second bricks 02 refer to the number of bricks arranged longitudinally between the front and rear bricks. The distribution density of the brick gaps 24 is controlled by a fixed number to ensure that the width of the brick gaps 24 is uniform.

[0048] Specifically, the first brick layer structure 1111 and the second brick layer structure 1112 limit the number of intermediate second bricks 02 to seven, ensuring that the gaps 24 between the bricks arranged longitudinally are evenly distributed. A fixed number of second bricks 02 create uniform gaps between the front and rear bricks of each layer, preventing localized high-temperature areas from forming due to insufficient gaps. Adjacent brick layers are arranged in an alternating pattern, maintaining a constant distance between the brick gaps 24, enhancing the continuity of the longitudinal airflow channel and reducing flue gas flow resistance. While maintaining the supporting strength of the brick row structure 110, the evenly distributed brick gaps 24 provide a stable channel for heat exchange, reducing temperature gradient differences.

[0049] Furthermore, the brick gap 24 includes a first brick gap 241 and a second brick gap 242. The first brick gap 241 is provided between the first brick 01 and the second brick 02, and the second brick gap 242 is provided between adjacent second bricks 02 and between the second brick 02 and the third brick 03. The longitudinal length of the first brick gap 241 is less than the longitudinal length of the second brick gap 242.

[0050] Since each brick row structure 110 is composed of a first brick layer structure 1111 and a second brick layer structure 1112 stacked vertically in an alternating manner, and the positions of the first brick 01 and the third brick 03 of the first brick layer structure 1111 are interchanged with the positions of the first brick 01 and the third brick 03 of the second brick layer structure 1112 respectively, the overall stability of the brick row structure 110 is enhanced by setting the brick gap 241 between the staggered front and rear edges to be smaller than the gap between other bricks.

[0051] The distinction between brick gap 1 241 and brick gap 2 242 ensures that the front and rear sides of the brick row structure 110 have relatively small brick gaps (along the longitudinal length). This means that when the bricks 00 on the front and rear sides of the brick row structure 110 are stacked vertically, the upper and lower surfaces have sufficient contact area to ensure structural stability.

[0052] Furthermore, the lengths of the first brick 01, the second brick 02, and the third brick 03 are equal, the thicknesses of the first brick 01, the second brick 02, and the third brick 03 are equal, and the width of the first brick 01 is less than the width of the second brick 02, and the width of the second brick 02 is less than the width of the third brick 03.

[0053] The ratio of the size of the first brick gap 241, the second brick gap 242, and the thickness of the first brick 01 is 1:2:2.

[0054] Wherein, the length of brick 00 refers to the length dimension of the brick extending horizontally, the width of brick 00 refers to the length dimension of the brick extending vertically, and the thickness of brick 00 refers to the length dimension of the brick extending vertically.

[0055] The first brick 01, located at the front of the first brick layer structure 1111 and at the rear of the second brick layer structure 1112, is the brick with the smallest width, and its smaller width provides structural stability to the front and rear ends of the brick row structure 110. The second brick 02, located in the middle of the brick layer structure 111, is a brick with a medium width (relative to the width of the first brick and the width of the third brick). The third brick 03, located at the rear of the first brick layer structure 1111 and at the front of the second brick layer structure 1112, is a brick with the largest width, and its maximum width forms a stepped layout to expand the airflow channels.

[0056] By defining the ratios of brick gap 1 (241) and brick gap 2 (242) to the brick dimensions, a differentiated airflow channel structure is constructed. Setting brick gap 1 (241) to a smaller gap creates a primary guiding channel between the first brick 01 and the second brick 02, ensuring structural load-bearing stability while guiding initial airflow diffusion. Enlarging brick gap 2 (242) to twice the size of brick gap 1 (241) creates the main airflow channel between the second bricks 02 and between the second brick 02 and the third brick 03, reducing flue gas flow resistance by increasing the gap cross-sectional area. The combination of these two gap sizes achieves a balance between structural strength and thermal performance, satisfying load-bearing requirements while improving heat exchange efficiency through optimized channel geometry.

[0057] In a preferred embodiment, the dimensions of the first brick 01 are 320mm×70mm×60mm, the dimensions of the second brick 02 are 320mm×110mm×60mm, and the dimensions of the third brick 03 are 320mm×125mm×60mm; the dimension of the first brick gap 241 is 30mm, and the dimension of the second brick gap 242 is 60mm.

[0058] Furthermore, the first brick layer structure 1111 has no more than nine layers, and the second brick layer structure 1112 has no more than nine layers.

[0059] By limiting the number of layers in both the first brick layer structure 1111 and the second brick layer structure 1112 to no more than nine, the thermodynamic performance deterioration caused by the stacking of layers is avoided from the perspective of overall structural height. When the first brick layer structure 1111 and the second brick layer structure 1112 are stacked alternately, the layer limit can prevent the effect of misalignment between bricks from weakening due to too many layers, ensuring that the staggered arrangement of the gaps 24 between the upper and lower bricks can continuously guide the airflow to form a stable vortex, thereby reducing local turbulent resistance.

[0060] In addition, the brick structure with no more than eighteen layers is specifically limited by the space at the top of the kiln.

[0061] By controlling the maximum number of layers in a single type of brick structure, the mechanical stability of the overall brick stack structure can be maintained, and the density of the gaps between adjacent brick layers can meet the requirements of uniform thermal field distribution, thereby mitigating the heat accumulation effect caused by excessive number of layers.

[0062] Furthermore, the ratio of the dimensions of the inter-row fire channel 21, the dimensions of the inter-row fire channel 22, and the length of the first brick 01 is 2:1:2.

[0063] By setting the width (length along the lateral direction) of the inter-row fire channel 21 to 320mm, a lateral expansion space is provided for the flow of flue gas in the kiln while ensuring the overall stability of the brick stack structure. This reduces the flow resistance of the flue gas in the fire channel and decreases the load on the exhaust system. Simultaneously, the width (length along the longitudinal direction) of the inter-row fire channel 22 is set to 105mm, forming ventilation channels with specific spacing in the longitudinal dimension. This avoids excessive heat loss in the kiln due to excessively wide fire channels and ensures uniform distribution of hot airflow between adjacent brick stacks, suppressing the formation of local temperature gradients. The combination of dimensions of the inter-row fire channel 21 and inter-row fire channel 22 synergistically optimizes the airflow organization in the kiln from both lateral and longitudinal dimensions, reducing exhaust energy consumption and improving the heating uniformity of lepidolite by improving heat exchange efficiency.

[0064] In a preferred embodiment, the size of the inter-row fire channel 21 is 320 mm, and the size of the inter-row fire channel 22 is 105 mm.

[0065] Furthermore, the size of the brick row gap 23 is in a 1:1 ratio to the thickness of the first brick 01.

[0066] Preferably, by limiting the dimension (length along the transverse direction) of the brick row gap 23 to 60mm, this technique provides a standardized transverse flow channel for the airflow inside the kiln while ensuring the stability of the brick row structure 110. This dimensional design is based on thermodynamic and fluid mechanics principles, avoiding both the structural strength reduction and insufficient packing density caused by excessively large gaps, and the surge in flue gas flow resistance caused by excessively small gaps. By precisely controlling the width of the brick row gap 23, the airflow distribution between the flue gas exhaust channels 22 and the brick row gap 23 can be effectively balanced, reducing the overall flue gas resistance and the energy consumption of the exhaust fan. This dimensional parameter, together with the inter-row flue channels 21 and 22, forms a multi-dimensional three-dimensional ventilation network, achieving stable control of negative pressure and efficient utilization of heat inside the kiln.

[0067] Furthermore, the number of the brick stack structures 100 is six, and the six brick stack structures 100 are arranged in a matrix distribution of two vertical columns multiplied by three horizontal rows.

[0068] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
