Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a slurry cooling device. Background Technology

[0002] In industrial production, some slurries require cooling, such as those used in battery manufacturing processes involving graphite, ternary lithium, and lithium iron phosphate. Cooling is typically achieved through condensation, for example, by exchanging heat between the condensate and the slurry.

[0003] However, current technologies that use top feeding and bottom discharging or horizontal feeding and discharging methods result in a short residence time of the slurry in the pipe, which cannot fully exchange heat. Therefore, it is necessary to increase the length of the pipe, which also increases the size of the equipment and occupies a large space. Furthermore, the heat exchange is carried out by straight pipe flow, which has low heat exchange efficiency and poor cooling effect. Utility Model Content

[0004] The main purpose of this invention is to provide a slurry cooling device, which aims to solve the technical problems of poor heat exchange efficiency of pipelines, low cooling effect, and inability of slurry to fully exchange heat in the prior art.

[0015] Optionally, the support portion is located at the middle position of the turbulence plate; or, there are multiple support portions, which are arranged at intervals along the axial direction of the turbulence plate.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] This utility model provides a slurry cooling device, which includes a cooling cylinder 10, a feed pipe 20, a discharge pipe 30, and turbulence plates 40. One end of the cooling cylinder 10 has a connecting cavity 11, and the other end of the cooling cylinder 10 has a feed cavity 12 and a discharge cavity 13 spaced apart from each other. The feed pipe 20 is disposed between the connecting cavity 11 and the feed cavity 12, with one end connected to the connecting cavity 11 and the other end connected to the feed cavity 12. The discharge pipe 30 is disposed between the connecting cavity 11 and the discharge cavity 13, with one end connected to the connecting cavity 11 and the other end connected to the discharge cavity 13. The turbulence plates 40 are provided inside both the feed pipe 20 and the discharge pipe 30.

[0038] Please refer to Figure 1 The cooling cylinder 10 has a receiving cavity, and a partition is provided at one end of the cooling cylinder 10 to separate the communicating cavity 11. At the other end of the cooling cylinder 10 opposite to the communicating cavity 11, another cavity is also separated by a partition, and a partition is provided between the cavities to separate the feed cavity 12 and the discharge cavity 13.

[0039] The cooling cylinder 10 is used to fill condensate or other refrigerant materials. The feed pipe 20 and the discharge pipe 30 are both located within the accommodating cavity of the cooling cylinder 10 and are surrounded by condensate. When the slurry flows in the feed pipe 20 and the discharge pipe 30, it can exchange heat with the condensate to achieve a cooling effect.

[0040] The cooling cylinder 10 has an outlet hole 16 and an inlet hole 15 on its side wall for replacing the condensate or other refrigerant inside the cooling cylinder 10.

[0041] A pipe 70 is provided at the bottom of the cooling cylinder 10. One pipe is used to connect the feeding chamber 12 to an external feeding device to input the slurry into the cooling cylinder 10 for cooling. The other pipe is used to connect the discharging chamber 13 to an external receiving device to recycle the cooled slurry.

[0042] The turbulence plate 40 has multiple blade-like structures that extend in a spiral shape. The turbulence plate 40 is a relatively mature technical solution in the prior art, and will not be described in detail here.

[0043] When the slurry flows from the discharge pipe 30 and the feed pipe 20, the turbulence plate 40 causes the fluid flow lines to become disordered, so that the fluid can exchange heat with the external condensate more fully, and there will be no situation where only the temperature of the fluid edge drops while the temperature of the center remains high.

[0044] To improve the convenience of the slurry cooling device, please refer to... Figure 5 A support 61 is also provided at the bottom of the cooling cylinder 10. The bottom of the support 61 has multiple sliding wheels and multiple foot cups 63, which can be raised and lowered relative to the support 61. The support 61 and the sliding wheels 62 enable rapid transfer. When the cooling cylinder 10 is in position, the foot cups 63 can be raised to lift the wheels 62 and fix the support 61. When further movement is needed, the foot cups 63 are lowered, and the support 61 is moved via the wheels 62.

[0045] In this invention, the feed chamber 12 and the discharge chamber 13 are located on the same side of the cooling cylinder 10, allowing the slurry to circulate within the cooling cylinder 10, increasing the flow length of the slurry, and ensuring sufficient contact and heat exchange with the condensate. Furthermore, the turbulence vanes 40 are provided in both the feed pipe 20 and the discharge pipe 30, thereby improving the heat transfer performance of the slurry, increasing its heat exchange efficiency, and enhancing the cooling effect.

[0046] Furthermore, there are multiple feed pipes 20, and the number of discharge pipes 30 is the same as the number of feed pipes 20, and the multiple feed pipes 20 and the multiple discharge pipes 30 are distributed in a polygonal array.

[0047] To further improve cooling efficiency, the flow rate of the slurry is indirectly increased by increasing the number of the feed pipe 20 and the discharge pipe 30, which enables heat exchange for more slurry at the same time.

[0048] It should be noted that the number of discharge pipes 30 and the number of feed pipes 20 should be the same to ensure that the feed amount and the discharge amount are consistent, and to prevent the feed pipes 20 and discharge pipes 30 from becoming clogged due to a large feed amount.

[0049] To improve cooling efficiency, the multiple inlet pipes and multiple outlet pipes 30 can be arranged in an array of a certain shape to reduce the overall space required. Please refer to... Figure 2 When only two discharge pipes 30 and two inlet pipes are provided, they can be arranged in a quadrilateral pattern, with each pipe located at one of the four vertices. However, when the number of discharge pipes 30 and inlet pipes is large, please refer to [the relevant regulations / references]. Figure 3 The multiple discharge pipes 30 and the multiple inlet pipes are arranged in an array to form a hexagon.

[0050] In addition, when there are a large number of inlet pipes and outlet pipes 30, the spacing between adjacent pipes should be ensured to avoid heat transfer interference and reduced cooling efficiency. For example, the spacing between two adjacent pipes 70 can be set to 45mm to 50mm.

[0051] The feed pipe 20 and the discharge pipe 30 are arranged parallel to each other. In one embodiment, please refer to... Figures 1-3 The feed chamber 12 and the discharge chamber 13 are both located at the bottom of the cooling cylinder 10, and the connecting chamber 11 is located at the top of the cooling cylinder 10. The feed pipe 20 and the discharge pipe 30 are vertically arranged. When the slurry enters the feed pipe 20 through the feed chamber 12, the slurry needs to overcome gravity and move from bottom to top, thereby further increasing its residence time in the feed pipe 20 and improving heat exchange efficiency. When the slurry enters the connecting chamber 11, the slurry is squeezed from the side near the feed pipe 20 to the side near the discharge pipe 30 and falls into the discharge pipe 30. Under the action of gravity, the slurry flows downward along the discharge pipe 30 to the discharge chamber 13, and is finally recovered through the pipe 70.

[0052] In another embodiment, please refer to Figure 4 The feeding chamber 12 and the discharging chamber 13 are both located on the left side of the cooling cylinder 10, the connecting chamber 11 is located on the right side of the cooling cylinder 10, and the feeding pipe 20 and the discharging pipe 30 are horizontally arranged.

[0053] Furthermore, when the feeding chamber 12 and the discharging chamber 13 are located on the side wall of the cooling cylinder 10, the feeding chamber 12 can be positioned above or below the discharging chamber 13, depending on the actual application scenario. By changing the positions of the feeding chamber 12 and the discharging chamber 13, the overall flexibility and adaptability of use are improved.

[0054] Further, please refer to Figure 6When the turbulence plate 40 is too long, in order to prevent the turbulence plate 40 from being deformed or broken due to long-term impact from the slurry flow, a support portion 41 is provided on the turbulence plate 40.

[0055] The support part 41 is a small protruding block, and the protrusion direction is consistent with the radial direction of the feed pipe 20. The feed pipe 20 is parallel to the discharge pipe 30, that is, consistent with the radial direction of the discharge pipe 30.

[0056] The support part 41 abuts against the inner wall of the feed pipe 20 or the discharge pipe 30, providing a support point for the turbulence plate 40 and maintaining the stability of the turbulence plate 40 during use.

[0057] The number of support portions 41 can be adjusted for turbulence vanes 40 of different lengths. When the turbulence vane 40 is short, the support portion 41 can be provided only in the middle position for auxiliary support. When the turbulence vane 40 is long, multiple support portions 41 can be arranged sequentially along the axial direction of the turbulence vane 40. The specific number and the spacing between two adjacent support portions 41 can be adjusted according to specific circumstances.

[0058] To prevent the support part 41 from rubbing against the inner wall of the feed pipe 20 or the discharge pipe 30, thus avoiding scraping and debris generation, the side of the support part 41 that contacts the inner wall is made into a spherical or curved surface. This reduces the contact area with the inner wall, thereby minimizing the possibility of debris generation while ensuring proper support and preventing contamination of the slurry.

[0059] Furthermore, when installing the turbulence plate 40, a fixing plate 50 is provided at one end of the turbulence plate 40. The fixing plate 50 has a certain length. The turbulence plate 40 is inserted along the axial direction of the feed pipe 20 or the discharge pipe 30. Finally, the fixing plate 50 is laid across the top of the discharge pipe 30 or the feed pipe 20 to achieve a fixing effect.

[0060] To prevent the slurry from lifting the turbulence plate 40 upwards during the flow process, a limiting device can be provided at the top of the fixed plate 50, and the limiting device can be snapped between the fixed plate 50 and the top wall of the cooling cylinder 10.

[0061] Furthermore, by changing the structure of the fixing plate 50, for example, the fixing plate 50 can be a perforated plate, and the turbulence plate 40 can be snapped into the hole 51 of the perforated plate by a component such as a bearing, thereby realizing the rotation of the turbulence plate 40.

[0062] The turbulence plate 40 can adaptively rotate based on the flowability of the slurry. For example, when the slurry density or viscosity is uneven, the slurry flowing over the turbulence plate 40 will compress it and cause it to rotate. By using rotation, blockages caused by the slurry's inability to flow smoothly under the above conditions can be avoided.

[0063] In addition, the rotation speed of the turbulence plate 40 can be controlled by setting a power device such as a motor to drive the turbulence plate 40 to adapt to various types of slurry and ensure the stability of the slurry flow process.

[0064] Furthermore, to prevent slurry blockage, a certain gap is reserved between the turbulence plate 40 and the inner wall of the feed pipe 20 or the discharge pipe 30. Please refer to [reference needed]. Figure 7 The spacing is the difference between the inner diameter c of the feed pipe 20 and the diameter d of the turbulence plate 40, and specifically, the spacing can be set between 3mm and 5mm. Furthermore, the thickness e of the turbulence plate 40 is 2mm to 5mm; the pitch b of the turbulence plate 40 is 180mm to 220mm. The support spacing a between two adjacent support parts 41 can be set to 300mm to 500mm.

[0065] Furthermore, the slurry cooling device also includes a heat insulation layer 14, which is disposed on the inner wall of the cooling cylinder 10. This reduces the absorption of heat energy from the air by the condensate or other refrigerant inside the cooling cylinder 10, thus preventing the temperature of the condensate or refrigerant from rising, ensuring heat exchange efficiency, and further improving the cooling effect.

[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
