[0038] See also Figures 1 to 6 The present embodiment provides a dispersion tank, comprising: a tank body 1; a heat exchange layer, arranged on the peripheral side of the tank body 1, a serpentine cooling channel is arranged in the heat exchange layer, and the cooling channel is suitable for passing a coolant; a water inlet 2 and a water outlet 3 are arranged on the heat exchange layer; the water inlet 2 and the water outlet 3 are both connected to the cooling channel.

[0039] In this embodiment, the water inlet 2 on the heat exchange layer can be connected to an external liquid supply device, and the water outlet 3 can be connected to an external drainage device. When heat is needed during the use of the tank body 1, the coolant flows into the cooling channel through the water inlet 2 and then flows out from the water outlet 3. When the coolant flows through the cooling channel, it exchanges heat with the interior of the tank body 1 to take away the heat, thereby reducing the temperature of the slurry during the dispersion process, avoiding the temperature increase from affecting the performance of the slurry, and avoiding the temperature increase from causing scalding to the operator during the operation, thereby improving the safety performance. In addition, the cooling channel is arranged in a serpentine shape, which can reduce the contact space between the coolant after heat exchange and the newly-flowing coolant, avoiding the coolant after heat exchange from contacting and exchanging heat with the newly-flowing coolant to reduce the cooling effect.

[0040] Example 2

[0041] As a further improvement to Example 1, Figures 3 to 5 As shown, the heat exchange layer includes a cylinder 4, which is sleeved on the outer circumference of the dispersion tank, and the top and bottom of the cylinder 4 are detachably connected with end covers 5; a plurality of through holes 6 are penetrated through the cylinder 4 along its axial direction, and the plurality of through holes 6 are evenly arranged around the axial direction of the cylinder 4; a plurality of connecting grooves 7 are provided on one side where the end cover 5 is connected to the cylinder 4, each connecting groove 7 connects two adjacent through holes 6, and the connecting grooves 7 on the end cover 5 at the top of the cylinder 4 are alternately arranged with the connecting grooves 7 on the end cover 5 at the bottom of the cylinder 4, and the plurality of connecting grooves 7 and the plurality of through holes 6 are alternately connected in sequence to form a cooling channel; the water inlet 2 and the water outlet 3 are both arranged on the cylinder 4.

[0042] In this embodiment, the heat exchange layer is split and consists of a cylinder 4 and two end covers 5, which is convenient for installation and disassembly to clean the interior of the cooling channel. The connecting grooves 7 on the two end covers 5 are staggered in the vertical direction to connect all the through holes 6 to form an alternately connected cooling channel, and the coolant flows alternately through each through hole 6 and the connecting groove in turn.

[0044] As a convertible implementation, the heat exchange layer may be a cooling pipe that is alternately connected in a serpentine shape, the cooling pipe surrounds the outer circumference of the tank body 1, and the water inlet 2 and the water outlet 3 are arranged on the cooling pipe. By arranging the cooling pipe and passing the coolant, the tank body 1 can be cooled, which saves materials and reduces costs.

[0045] Based on the above implementation, in a specific implementation, as Figure 3 As shown, the cylinder 4 and the tank body 1 are integrated.

[0046] In this embodiment, the cylinder 4 and the tank body 1 are integrated to improve the structural strength.

[0047] Based on the above implementation, in a specific implementation, as Figure 2 As shown, the top of the tank body 1 is provided with an exhaust hole 8 communicating with the inner cavity of the tank body 1 , and the exhaust hole 8 is suitable for communicating with an external vacuum device.

[0048] In this embodiment, the exhaust hole 8 is provided and a vacuum suction force is generated by cooperating with an external vacuum device to remove the water vapor generated inside the tank body 1 during the dispersion process of the slurry, thereby improving the dispersion quality of the slurry.

[0049] Specifically, the exhaust hole 8 is detachably connected with an air pipe joint.

[0050] In this embodiment, an air pipe joint is provided to facilitate connection to an external vacuum device, thereby facilitating installation and replacement.

[0051] Based on the above implementation, in a specific implementation, as Figure 3 As shown, a partition block 9 is provided in the cooling channel; the water inlet 2 and the water outlet 3 are located at two ends of the partition block 9, and the water inlet 2 and the water outlet 3 are suitable for being separated by the partition block 9.

[0052] In this embodiment, the water inlet 2 and the water outlet 3 are separated by a partition block 9, so that the water inlet 2 and the water outlet 3 are not connected, which can avoid the coolant after heat exchange from contacting with the newly flowing coolant, avoid the coolant after heat exchange from contacting with the newly flowing coolant for heat exchange, and can completely discharge the coolant after heat exchange, further improving the cooling effect.

[0053] Based on the above implementation, in a specific implementation, as Figure 1 As shown, a temperature detecting member 10 is provided on the tank body 1 .

[0054] In this embodiment, the temperature inside the tank body 1 can be detected in real time through the temperature detection element 10 .

[0055] Specifically, the temperature detection element 10 is a temperature sensor.

[0056] Based on the above implementation, in a specific implementation, as Figure 3 As shown, the water inlet 2 is detachably connected to the first water pipe connector 11 .

[0057] In this embodiment, the first water pipe joint 11 is provided to facilitate connection with an external liquid supply device, and is convenient for installation and replacement.

[0058] Specifically, the first water pipe joint 11 is threadedly connected to the water inlet 2, which is convenient for installation and disassembly.

[0059] Based on the above implementation, in a specific implementation, as Figure 3 and Figure 4As shown, the water outlet 3 is detachably connected to a second water pipe connector 12 .

[0060] In this embodiment, the second water pipe joint 12 is provided to facilitate connection to external drainage equipment, and is convenient for installation and replacement.

[0061] Specifically, the second water pipe joint 12 is threadedly connected to the water outlet 3, which is convenient for installation and disassembly.

[0062] The working principle of the dispersion tank provided in this embodiment is: the water inlet 2 on the heat exchange layer can be connected to the external liquid supply device through the first water pipe joint 11, and the water outlet 3 can be connected to the external drainage device through the second water pipe joint 12. When heat dissipation is required during the use of the tank body 1, Figure 6 As shown, by letting the coolant flow into the cooling channel through the water inlet 2 and then flowing out from the water outlet 3, the coolant exchanges heat with the inside of the tank body 1 when flowing through the cooling channel, takes away the heat, reduces the temperature of the slurry during the dispersion process, avoids the temperature rise affecting the performance of the slurry, and avoids the temperature rise causing scalding of the operator during the operation, thereby improving the safety performance. In addition, the cooling channels are alternately connected, that is, arranged in a serpentine shape, which can reduce the contact space between the coolant after heat exchange and the newly-flown coolant, avoid the contact and heat exchange between the coolant after heat exchange and the newly-flown coolant to reduce the cooling effect; in addition, during the slurry dispersion process, the water vapor in the tank body 1 can be removed through the exhaust hole 8 by an external vacuum device, thereby improving the dispersion effect of the slurry. The invention solves the problem that the existing disperser has a rapid temperature rise in the dispersion tank during high-speed dispersion, which may cause the slurry to change and thus affect the performance of the battery, and the technical problem that the operator is easily scalded when changing the slurry.

[0065] In this embodiment, when the slurry needs to be dispersed, the driving device 23 drives the dispersion component to rotate in the dispersion tank to disperse the slurry. During the dispersion process, the purpose of heat dissipation can be achieved by adopting the dispersion tank of Example 1 or Example 2. The specific principle is the same as that of Example 1 or Example 2, which avoids the temperature increase from affecting the performance of the slurry, and at the same time avoids the temperature increase from causing scalding to the operator during the operation, thereby improving safety performance.

[0068] In this embodiment, by providing a liquid supply device, and the water outlet and water inlet of the liquid supply device are respectively connected to the water inlet 2 and the water outlet 3, the cooling liquid can be circulated and the waste of the cooling liquid can be avoided.

[0070] It should be noted that the water tank 14 is provided with cooling liquid.

[0071] In this embodiment, when the dispersion tank needs to be cooled, the submersible pump 15 is started to input the coolant in the water tank 14 into the water inlet 2 of the dispersion tank through the water outlet of the submersible pump 15 and the first pipeline 16, and then flows back to the water tank 14 through the second pipeline 17 after passing through the cooling channel, thereby realizing the recycling of the coolant.

[0072] Specifically, if Figure 2 As shown, the dispersion assembly includes a dispersion rod 18 and a dispersion blade 19. The dispersion rod 18 is rotatably arranged in the tank body 1 along the vertical direction. The dispersion blade 19 is arranged on the dispersion rod 18. The dispersion rod 18 is drivingly connected to the output end of the driving device 23. The driving device 23 drives the dispersion rod 18 to rotate to drive the dispersion blade 19 to disperse the slurry.

[0073] Furthermore, if Figure 2 As shown, the dispersion component also includes a top slurry 20 and a pressing slurry 21, which are arranged on the dispersion rod 18, and the top slurry 20 and the pressing slurry 21 are respectively located above and below the dispersion blade 19, so as to facilitate lifting and pressing the slurry and improve the uniformity of slurry dispersion.

[0074] Specifically, a plurality of supporting feet 22 are provided at the bottom of the supporting base 13 to improve stability.

[0075] Specifically, the driving device 23 includes a driving motor, which is detachably connected to the supporting seat 13 via a fixing seat, so as to facilitate disassembly and installation. The output end of the driving motor is drivingly connected to the dispersion component, and is suitable for driving the dispersion component to rotate.

[0076] The specific working principle of the disperser provided in this embodiment is as follows: when the slurry needs to be dispersed, the dispersion rod 18 is driven by the driving motor, and the spreading rod drives the dispersion blades 19, the pressing slurry 21 and the top slurry 20 to rotate in the dispersion tank to disperse the slurry, and at the same time, the submersible pump 15 is started, and the coolant in the water tank 14 is input to the water inlet 2 of the dispersion tank through the water outlet of the submersible pump 15 and the first pipeline 16, and then flows back to the water tank 14 through the second pipeline 17 after passing through the cooling channel, so as to realize the circulation of the coolant, cool down the dispersion tank during the dispersion process, avoid the temperature rise affecting the performance of the slurry, and avoid the temperature rise causing scalding of the operator during the operation, thereby improving the safety performance. The existing disperser solves the problem that the dispersion tank has a rapid temperature rise during the high-speed dispersion process, which may cause the slurry to change and thus affect the performance of the battery, and the technical problem that the operator is easily scalded when changing the slurry.

[0077] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
