TECHNICAL FIELD

Dry electrode raw materials have unique physical properties, that is, they cannot withstand extrusion pressure and are prone to caking under pressure, thereby affecting the performance and quality of the electrode.

However, this traditional method has significant defects when applied to dry electrode raw materials: the extrusion pressure generated during screw rotation inevitably acts on the raw materials, causing the raw materials to caking, which seriously affects the uniformity of subsequent electrode preparation and the quality of finished products.

[0041] Since the existing electrode raw material is usually moved along a preset path through a screw feeding system, but this method will cause the raw material to be caked when applied to dry-process electrode raw material, thereby affecting the uniformity of subsequent electrode preparation and affecting the quality of the electrode. Therefore, the embodiment of the present application installs a scattering assembly 400 on the material shell 100 to scatter the raw material in the material shell 100, thereby preventing the raw material from caking during the discharging process.

[0042] The embodiment of the present application provides a material device, in particular, the discharging device includes a material shell 100, a discharge port 200, a quantitative discharging assembly 300 and a scattering assembly 400.

[0043] The discharge position of the material shell 100 is provided with a discharge port 200, the quantitative discharging assembly 300 is installed at the position of the discharge port 200, the quantitative discharging assembly 300 is used for quantitative discharging of the material in the material shell 100, and the scattering assembly 400 is installed on the material shell 100. The scattering assembly 400 is used for scattering the material in the material shell 100.

[0044] Please refer to Figure 1 and Figure 2 It is shown that in the initial state, the material shell 100 receives the raw material conveyed from the outside, and as the raw material accumulates inside the material shell 100, the raw material at the bottom will be caked, which may cause the caked raw material to be discharged when the quantitative discharging assembly 300 discharges, and the caked raw material may also affect the amount of discharging. Therefore, when the raw material in the material shell 100 reaches a certain height, the inside of the material shell 100 can be stirred by the scattering assembly 400 to achieve scattering or the raw material at the bottom can be gradually lifted upwards, and then dropped when reaching a certain height to achieve the function of scattering, thereby preventing the caking phenomenon.

[0045] The material shell 100 includes a scattering cavity shell 110, a blocking cavity shell 120, a discharging cavity shell 130 and a cover plate 140.

[0046] In one embodiment, the blocking cavity shell 120 is fixedly connected to the discharge end of the scattering cavity shell 110, and an opening and closing valve 700 is installed on the blocking cavity shell 120. The discharging cavity shell 130 is fixedly installed on the discharge end of the blocking cavity shell 120. The opening and closing valve 700 is used to control the blocking or communication between the scattering cavity shell 110 and the blocking cavity shell 120. The discharge port 200 is arranged on the discharge end of the discharging cavity shell 130. The cover plate 140 is fixedly installed on the opening of the scattering cavity shell 110, and is used to at least partially close the opening of the scattering cavity shell 110. The cross-sectional area of the discharging cavity shell 130 gradually decreases along the discharging direction.

[0047] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 In this embodiment, the scattering cavity shell 110, the blocking cavity shell 120 and the discharging cavity shell 130 are sequentially connected and installed along the height direction. The scattering cavity shell 110 forms a material scattering cavity inside. The blocking cavity shell 120 forms a blocking cavity inside. The discharging cavity shell 130 forms a discharging cavity inside. The opening and closing valve 700 is arranged in the blocking cavity shell 120 to block or communicate the scattering cavity shell 110 and the discharging cavity shell 130. The cover plate 140 is used to close the opening of the scattering cavity shell 110. The scattering assembly 400 is installed on the cover plate 140, and the scattering structure of the cover plate 140 is located in the scattering cavity shell 110.

[0048] In one embodiment, in order to facilitate the external raw material to be conveyed into the scattering cavity shell 110, the cover plate 140 does not completely close the opening of the scattering cavity shell 110, or a feeding port (not labeled in the figure) is arranged on the cover plate 140, so as to facilitate the external material to enter the scattering cavity shell 110 and provide raw materials for the scattering cavity shell 110.

[0049] Please refer to Figure 1 、 Figure 2 and Figure 3 By opening the blocking cavity shell 120 through the opening and closing valve 700, the scattering cavity shell 110 and the discharging cavity shell 130 are communicated, so that the amount of raw material from the scattering cavity shell 110 entering the discharging cavity shell 130 can be controlled, thereby preventing the raw material in the discharging cavity shell 130 from caking to a certain extent.

[0050] For example, the opening and closing valve 700 is a plug valve.

[0051] In one embodiment, when the raw material in the scattering cavity shell 110 exceeds the preset height, the raw material in the scattering cavity shell 110 can be scattered by the scattering assembly 400, so as to prevent the raw material at the bottom of the scattering cavity shell 110 from caking due to the excessive height of the raw material.

[0052] A first level sensor (not shown in the figure) is installed inside the dispersing chamber shell 110, and a second level sensor (not shown in the figure) is installed inside the discharging chamber shell 130.

[0053] In one embodiment, a first material level sensor is installed in the dispersing chamber shell 110 to determine whether the raw material in the dispersing chamber shell 110 has reached a preset height. When the first material level sensor detects that the height of the raw material in the dispersing chamber shell 110 has reached the preset height, the dispersing component 400 can be activated to disperse the raw material in the dispersing chamber shell 110, thereby preventing the raw material in the dispersing chamber shell 110 from clumping.

[0054] In one embodiment, a second material level sensor located in the feeding chamber 130 is used to determine whether the height of the raw material in the feeding chamber 130 has reached a preset height. When the preset height is reached, the opening size of the discharge port 200 can be controlled by the opening and closing valve 700, thereby controlling the amount of raw material entering the feeding chamber 130 and preventing agglomeration due to excessive raw material.

[0055] In one embodiment, the specific type and model of the first and second level sensors are not limited here; that is, any sensor that can detect the presence of material is acceptable.

[0056] The quantitative discharging assembly 300 includes a first rotary drive 310, the output end of which is equipped with a first rotary shaft 320. The first rotary shaft 320 is at least partially located inside the discharge chamber shell 130, and a spiral quantitative roller 330 is mounted on the first rotary drive 310.

[0057] See Figure 3 and Figure 4 As shown, the first rotating shaft 320 is located at the discharge port 200. The first rotating shaft 320 is rotatably installed between the two inner walls of the discharge chamber shell 130. A spiral metering roller 330 is installed on the first rotating shaft 320. When the first rotating shaft 320 rotates, it will drive the spiral metering roller 330 to rotate, thereby causing the spiral metering roller 330 to transport a certain amount of raw material from the discharge chamber shell 130 to the discharge port 200, thus realizing the discharge.

[0058] In one embodiment, in order to enable the first rotating shaft 320 to rotate, a first rotating drive 310 is provided on the outer side of the feeding chamber shell 130. The output shaft of the first rotating drive 310 can be connected to the first rotating shaft 320 through a coupling, thereby enabling the first rotating drive 310 to drive the first rotating shaft 320 and the spiral metering roller 330 to rotate.

[0059] For example, the first rotary drive 310 is a motor. In order to meet the requirements of driving the first rotary shaft 320 and the spiral metering roller 330 to rotate, a reducer can be installed at the output shaft of the first rotary drive 310. By reducing the speed of the first rotary drive 310 through the reducer, the speed of the first rotary drive 310 can be reduced and the torque can be increased, thereby meeting the needs of the first rotary shaft 320 and the spiral metering roller 330 to rotate. For example, the reducer can be a planetary reducer, a spur gear reducer or a helical gear reducer, etc. The specific type and model are not limited here, and can be selected and designed according to the actual working conditions.

[0060] The cross-section of the feeding chamber shell 130 gradually decreases from top to bottom to accommodate the size of the spiral metering roller 330. Compared with conventional metering rollers, the spiral metering roller 330 disperses the force in the axial direction when it rotates and impacts the raw material, reducing the occurrence of extrusion.

[0061] The dispersing assembly 400 includes a second rotary drive 410 fixedly mounted on the cover plate 140. The second rotary drive 410 has a second rotary shaft 420 mounted on its shaft. The second rotary shaft 420 is at least partially located inside the dispersing chamber shell 110. The second rotary drive 410 has blades 430 mounted on it.

[0062] See Figure 2 , Figure 3 as well as Figure 6 As shown, a second rotary drive 410 is installed on the upper surface of the cover plate 140, and a second rotary shaft 420 is installed at the center of the cover plate 140. The second rotary shaft 420 extends into the dispersing chamber 110. The second rotary drive 410 and the second rotary shaft 420 are connected for transmission, that is, the second rotary drive 410 can drive the second rotary shaft 420 to rotate. In order to disperse the raw materials in the dispersing chamber 110 by the rotation of the second rotary shaft 420, blades 430 for dispersing the raw materials can be installed on the outer surface of the second rotary shaft 420. Therefore, the second rotary drive 410 can drive the second rotary shaft 420 and the blades 430 to rotate to disperse the raw materials in the dispersing chamber 110.

[0063] For example, the blade 430 can be a common spiral blade, auger blade, etc. In this embodiment, the blade 430 is an auger blade, and the end of the auger blade is located at the end of the dispersing cavity shell 110 near the blocking cavity shell 120. When the second rotating shaft 420 and the blade 430 rotate, they can drive the material at the bottom of the dispersing cavity shell 110 to be lifted and thrown to the top. Then the material falls under the action of gravity, thereby realizing the dispersal of the material and ensuring that the material at the bottom will not be squeezed and clump together.

[0064] The lower cavity shell 130 is provided with at least one blowing assembly 500 for blowing the material from the scattering cavity shell 110, the blowing assembly 500 comprises a gas inlet shell 510 fixedly installed at the material inlet position of the lower cavity shell 130, the inner wall of the gas inlet shell 510 towards the lower cavity shell 130 is provided with an exhaust port 520, the gas inlet shell 510 and the lower cavity shell 130 are in internal communication through the exhaust port 520, and at least one gas inlet port 530 is formed in the gas inlet shell 510.

[0065] Referring to Figure 7 , Figure 8 , the blowing assembly 500 is arranged on the lower cavity shell 130, so that the raw material is blown during the falling process of the raw material from the scattering cavity shell 110 to the lower cavity shell 130, thereby preventing the raw material from gathering and forming lumps, increasing the air content in the lower cavity shell 130, and keeping the raw material powder in a loose state.

[0066] Please refer to Figure 7 , Figure 8 , when it is necessary to blow air into the lower cavity shell 130, the gas inlet port 530 can be connected to an external gas device, the gas from the gas device enters the gas inlet shell 510 through the gas inlet port 530, and then the gas is discharged into the lower cavity shell 130 through the exhaust port 520, thereby increasing the air content in the lower cavity shell 130, and the air can be blown to the falling raw material powder, thereby keeping the raw material powder in a loose state, thereby preventing lumps from forming.

[0067] The material outlet 200 is provided with a material guiding assembly 600, the material guiding assembly 600 comprises a bottom plate 610 fixedly installed on the lower cavity shell 130 at the position of the material outlet 200, side plates 620 are arranged at both side edges of the bottom plate 610, the bottom plate 610 and the side plates 620 define a material guiding channel, at least one adjusting plate 630 is rotatably installed on at least one side plate 620, and the adjusting plate 630 adjusts the included angle between the adjusting plate 630 and the side plate 620 through a screwing member.

[0068] Referring to Figure 1 , Figure 2 , Figure 3 , and Figure 9 , the bottom plate 610 is at the position of the material outlet 200, and the material guiding channel formed by the bottom plate 610 and the side plates 620 guides the raw material from the material outlet 200, in order to enable the raw material to be concentrated and conveyed to the position, the adjusting plate 630 can be rotatably installed on the side plate 620, and the opening size of the material guiding channel is adjusted by adjusting the included angle between the adjusting plate 630 and the side plate 620.

[0069] In one embodiment, at least one adjusting plate 630 is mounted on each side plate 620, and the opening of the material guiding channel is adjusted by adjusting the angle between each side adjusting plate 630 and the side plate 620.

[0070] In the embodiment, the end of the adjusting plate 630 on each side plate 620 is also rotatably mounted with an adjusting plate 630, and the angle between the adjusting plates 630 on each side can also be adjusted. Specifically, the adjacent adjusting plates 630 on each side can be fastened by bolts, and the adjusting plates 630 on each side and the side plate 620 can also be fastened by bolts. When the opening of the material guiding channel needs to be adjusted, the angle can be adjusted by reducing the fastening force of the bolts, and the adjusted angle can be maintained by increasing the fastening force of the bolts after the adjustment is completed.

[0071] The cover plate 140 is fixedly mounted with a plurality of uniformly distributed quick chucks 800, and the quick chucks 800 are used for detachably connecting the cover plate 140 and the scattering cavity shell 110.
