Description

Technical Field

[0001] This invention relates to the field of material mixing technology, and more specifically, to a material mixer device. Background Technology

[0002] The lithium-ion battery separator is one of the key internal components of a lithium-ion battery. Commercially available separator materials are mainly polyolefin separators, primarily made of polyethylene and polypropylene. The separator is a crucial internal component. Located between the positive and negative electrodes, its main function is to separate the active materials of the two electrodes, preventing short circuits due to contact, while allowing the rapid transport of charged ions. To improve the separator's heat resistance, a slurry is coated onto it. This slurry enhances the separator's heat resistance, thus protecting the positive and negative electrodes of the lithium-ion battery. A key component of the slurry is "para-aramid." During the synthesis of the slurry, para-aramid requires two fluids to be thoroughly mixed in a specific ratio before a chemical reaction to produce the slurry.

[0003] When mixing two materials, existing mixing equipment typically uses nozzles and annular channels to separately feed the two materials into the mixing channel. This simple addition mixing method, which mixes the two materials from the surface, results in poor mixing effect. Over time, the two materials are prone to solidify and agglomerate. Furthermore, the two materials are prone to uneven mixing within a short contact time. Summary of the Invention

[0004] This invention proposes a material mixer device that solves the problem of uneven material mixing in related technologies.

[0005] The technical solution of the present invention is as follows:

[0006] A material mixer device, comprising

[0007] The feeding chamber has an inlet and a outlet, both of which are connected to the feeding chamber.

[0008] A mixing channel is located in the middle of the feed chamber.

[0009] A cover plate is disposed above the feeding chamber, and a gap is formed between the feeding chamber and the cover plate, which serves as a feeding channel. The feeding channel is located outside the mixing channel and is in communication with the mixing channel.

[0010] An annular sealing body is disposed between the cover plate and the feed chamber, thereby sealing the periphery of the feeding channel. The feed port communicates with the mixing channel through the feeding channel.

[0011] The first feed pipe is disposed on the cover plate.

[0012] A first annular nozzle is disposed at the lower end of the first feed pipe and faces the mixing channel. The first material enters the mixing channel through the first annular nozzle.

[0013] The second feed pipe is disposed inside the first feed pipe.

[0014] The second annular nozzle is located at the lower end of the second feed pipe and is inside the first annular nozzle. The discharge direction of the second annular nozzle is towards the inner wall of the mixing channel. The second material enters the mixing channel in two paths through the feed channel and the second annular nozzle respectively.

[0015] As a further technical solution, the nozzle of the first annular nozzle includes

[0016] A first oblique nozzle and a second oblique nozzle are respectively disposed on the outer ring and inner ring of the first annular nozzle. The discharge direction of the first oblique nozzle is towards the feeding channel, and the discharge direction of the second oblique nozzle is towards the discharge position of the second annular nozzle.

[0017] As a further technical solution, it also includes

[0018] The drive motor is mounted on the cover plate.

[0019] The drive gear is located at the output end of the drive motor.

[0020] A driven gear is disposed on the second feed pipe and is located outside the first feed pipe. The driven gear is meshed with the driving gear, and the second feed pipe is rotatably connected to the first feed pipe.

[0021] As a further technical solution, it also includes

[0022] A flexible lever is disposed at the lower end of the driven gear.

[0023] A first feed connector is connected to the first feed pipe, which is located below the driven gear. The first feed pipe is rotatably connected to the cover plate. When the elastic lever rotates, it contacts the upper part of the outer wall of the first feed connector to rotate the first feed pipe.

[0024] An elastic reset rod is disposed on the cover plate. The elastic reset rod contacts the outer wall of the first feed pipe and is used to reset the first feed pipe after it is moved by the elastic lever.

[0025] As a further technical solution, it also includes

[0026] A limiting rotating tube is disposed at the lower end of the second annular nozzle, and the limiting rotating tube is located in the upper part of the mixing channel.

[0027] As a further technical solution, it also includes

[0028] The second feed pipe is rotatably and sealed to the feed end of the second feed pipe, and is used to communicate with the second material from the outside.

[0029] As a further technical solution, the cover plate is connected to the feed chamber by bolts.

[0030] As a further technical solution, it also includes

[0031] A flange is provided at the lower end of the feed chamber, the flange is located at the lower part of the mixing channel, and the flange is used to connect to the extruder.

[0032] The working principle and beneficial effects of this invention are as follows:

[0033] 1. In this invention, the first material enters the mixing channel through the first feed pipe and the first annular nozzle, and the second material enters the mixing channel through two paths. The two paths of the second material enter the mixing channel through the feed chamber and the second feed pipe, respectively, and the first material is located in the middle of the two paths of the second material. The first material enters from the middle, which reduces the mixing stroke of the material, improves the ability of the first material to penetrate and mix into the interior of the second material when the nozzle is sprayed, which is beneficial to improve the mixing uniformity of the first material and the second material, and reduces the mixing time, reduces the occurrence of solidification before uniform mixing, and improves the mixing quality.

[0034] 2. The first annular nozzle sprays out in two directions, which can better impact and mix with the second material coming in from the feeding channel and the second material coming in from the second feed pipe, thereby improving the mixing efficiency and mixing effect.

[0035] 3. The drive motor can drive the second feed pipe to rotate, so that the second annular nozzle can rotate circumferentially while maintaining real-time material output from the second annular nozzle. This avoids uneven material output from a single position of the nozzle and improves the overall mixing uniformity.

[0036] 4. The elastic lever can be used in conjunction with the elastic reset lever to enable the first feed tube to reciprocate within a small angle, avoiding uneven discharge at a certain position for a long time due to the fixed discharge position, and improving the mixing uniformity.

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] like Figures 1-10 As shown, this embodiment proposes a material mixer device, including...

[0051] The feeding chamber 1 has a feeding port 2 and a feeding port 3, both of which are connected to the feeding chamber 1.

[0052] Mixing channel 4, which is located in the middle of the feed chamber 1.

[0053] A cover plate 5 is disposed above the feeding chamber 1, and there is a gap between the feeding chamber 1 and the cover plate 5. This gap forms a feeding channel 6, which is located outside the mixing channel 4 and is connected to the mixing channel 4.

[0054] An annular sealing body 7 is disposed between the cover plate 5 and the feed chamber 1, thereby sealing the periphery of the feed channel 6. The feed port 3 is connected to the mixing channel 4 through the feed channel 6.

[0055] The first feed pipe 8 is disposed on the cover plate 5.

[0056] A first annular nozzle 9 is disposed at the lower end of the first feed pipe 8 and faces the mixing channel 4. The first material enters the mixing channel 4 through the first annular nozzle 9.

[0057] The second feed pipe 10 is disposed inside the first feed pipe 8.

[0058] The second annular nozzle 11 is disposed at the lower end of the second feed pipe 10 and is located inside the first annular nozzle 9. The discharge direction of the second annular nozzle 11 is towards the inner wall of the mixing channel 4. The second material enters the mixing channel 4 through the feeding channel 6 and the second annular nozzle 11 respectively.

[0059] In this embodiment, during use, the feed end of the feed inlet 2 is connected to the first material outside, and the feed chamber 1 is connected to the feed channel 6 through the feed port 3. The second material enters the mixing channel 4 in two directions and forms a clamp around the first material. A portion of the second material enters the mixing channel 4 through the feed inlet 2, the inside of the feed chamber 1, the feed port 3, and the feed channel 6. The feed channel 6 is annular, and the second material enters the mixing channel 4 from all sides. Another portion of the second material is sprayed into the mixing channel 4 through the second feed pipe 10 and the second annular nozzle 11. The first material enters the mixing channel 4 through the first feed pipe 8 and the second annular nozzle 11, and the first material is located in the middle of the two second materials for material mixing. The mixed material gradually slides down the inner wall of the mixing channel 4 and finally forms a solid to complete the shaping and production.

[0060] The first material is located between the two second materials. Since the second material has a relatively large volume, the first material enters from the middle, reducing the mixing distance between the materials. With the same supply, the second material is supplied in two separate streams. The thickness of each stream of the second material is significantly reduced compared to the single-stream supply. This is beneficial for improving the ability of the first material to penetrate and mix into the interior of the second material when sprayed from the nozzle. It also helps to improve the uniformity of mixing between the first and second materials, reduce the mixing time, reduce the occurrence of solidification before uniform mixing, and improve the mixing quality.

[0061] This invention can be used for mixing terephthaloyl chloride and methylpyrrolidone, with terephthaloyl chloride as the first material and methylpyrrolidone as the second material. The feed chamber 1 can be composed of two sealed upper and lower parts, which facilitates production assembly and is a conventional technology.

[0062] Furthermore, the nozzle of the first annular nozzle 9 includes

[0063] The first oblique nozzle 12 and the second oblique nozzle 13 are respectively disposed on the outer ring and the inner ring of the first annular nozzle 9. The discharge direction of the first oblique nozzle 12 is towards the feeding channel 6, and the discharge direction of the second oblique nozzle 13 is towards the discharge position of the second annular nozzle 11.

[0064] In this embodiment, the first annular nozzle 9 is located between the feeding channel 6 and the second annular nozzle 11, meaning the first material is located between the two paths of the second material, and the final mixed material slides down the side wall of the mixing channel 4. The nozzle of the first annular nozzle 9 sprays out in two paths on the outer and inner rings with different directions. Both discharge materials are uniformly sprayed in annular shapes. The first oblique nozzle 12 obliquely sprays part of the first material onto the path of the second material coming in from the material channel, and the second oblique nozzle 13 obliquely sprays part of the first material onto the path of the second material sprayed out by the second annular nozzle 11. The impact force of the first material sprayed out by the first annular nozzle 9 improves the mixing effect of the first material and the two paths of the second material. The material sprayed out by the second annular nozzle 11 points towards the inner wall of the mixing channel 4.

[0065] Furthermore, it also includes

[0066] Drive motor 14, the drive motor 14 is mounted on the cover plate 5.

[0067] The drive gear 15 is located at the output end of the drive motor 14.

[0068] Driven gear 16 is disposed on the second feed pipe 10 and is located outside the first feed pipe 8. Driven gear 16 is meshed with the driving gear 15. The second feed pipe 10 is rotatably connected to the first feed pipe 8.

[0069] In this embodiment, as Figure 7 As shown, when the drive motor 14 starts, it can drive the second feed pipe 10 to rotate. The second annular nozzle 11 sprays material during rotation, avoiding the situation of uneven material mixing that may exist in a fixed position. Due to the viscosity of the material, the material discharge at a certain position is relatively uneven compared to other positions. If it remains stationary in one position for a long time, that position will always be in a state of uneven material, resulting in uneven material mixing. The rotation setting of the second annular nozzle 11 can effectively reduce the situation of unevenness at a certain position for a long time. During the rapid rotation, it reduces the accumulation of uneven material in a fixed position and reduces the degree of uneven mixing.

[0070] Furthermore, it also includes

[0071] A flexible lever 17 is disposed at the lower end of the driven gear 16.

[0072] The first feed pipe 18 is connected to the first feed pipe 8, which is located below the driven gear 16. The first feed pipe 8 is rotatably connected to the cover plate 5. The elastic lever 17 contacts the upper part of the outer wall of the first feed pipe 18 when rotating, and is used to rotate the first feed pipe 8.

[0073] An elastic reset rod 19 is disposed on the cover plate 5. The elastic reset rod 19 contacts the outer wall of the first feed pipe 18 and is used to reset the first feed pipe 8 after it is moved by the elastic lever 17.

[0074] In this embodiment, as Figure 10 As shown, when the driven gear 16 rotates, it drives the elastic lever 17 to rotate, for example, by rotating counterclockwise. The elastic reset lever 19 is located on the right side of the first feed pipe 18. During the process of the elastic lever 17 turning from the left side to the right side of the first feed pipe 18, it drives the first feed pipe 18 to rotate a small angle. The elastic reset lever 19 undergoes adaptive deformation and accumulates elastic restoring force. Finally, the elastic restoring force is greater than the pushing force of the elastic lever 17 on the first feed pipe 18, and the elastic lever 17 undergoes bending deformation and slides out from above the first feed pipe 8. The elastic reset lever 19 drives the first feed pipe 18 to reset. When the elastic lever 17 rotates to the left side of the first feed pipe 18 again, the above action is repeated, and the first feed pipe 8 forms a periodic reciprocating oscillation, reducing the uneven accumulation of material in a fixed position and improving the mixing effect.

[0075] The end of the elastic lever 17 can be relative to the middle of the outer side of the first feed tube 8, and the end of the elastic reset lever 19 can be higher than the first feed tube 8, so that the elastic reset lever 19 can better intercept the first feed tube 8 and prevent the first feed tube 8 from detaching from the elastic reset lever 19. At the same time, when the first feed tube 8 is connected to the outside, it needs to be used with a soft structure or a swingable structure to cooperate with the swinging action of the first feed tube 8. Meanwhile, the external connection structure will also limit the rotation angle of the first feed tube 8.

[0076] Furthermore, it also includes

[0077] The limiting rotating tube 20 is disposed at the lower end of the second annular nozzle 11 and is located in the upper part of the mixing channel 4.

[0078] In this embodiment, the limiting rotating tube 20 is located at the lower end of the second annular nozzle 11 and rotates synchronously. It can limit the sprayed first and second materials, preventing some materials from being sprayed into the middle of the mixing channel 4 and failing to gather and mix well. At the same time, the rotation of the limiting rotating tube 20 can drive the rotation of some of the sprayed first and second materials, which is beneficial to improving the flow mixing effect.

[0079] Furthermore, it also includes

[0080] The second feed pipe 21 is rotatably and sealedly connected to the feed end of the second feed pipe 10, and is used to communicate with the external second material.

[0081] In this embodiment, the second feed pipe 21 is rotatably connected to the second feed pipe 10, which facilitates the supply of the second material to the outside when the second feed pipe 10 is rotatably set.

[0082] Furthermore, the cover plate 5 is connected to the feed chamber 1 by bolts.

[0083] In this embodiment, the cover plate 5 is bolted to the feed chamber 1, which facilitates changing the thickness of the gap between the cover plate 5 and the feed chamber 1, thereby adjusting the inflow rate of the first material from the feed channel 6. Changing the thickness of the annular seal 7 changes the height of the feed channel 6, thus regulating the flow rate. The annular seal 7 can be a rubber ring or the like, located around the feed port 3.

[0084] Furthermore, it also includes

[0085] Flange 22 is disposed at the lower end of the feed chamber 1. Flange 22 is located at the lower part of the mixing channel 4 and is used to connect the extruder.

[0086] In this embodiment, flange 22 can be easily connected to install an extruder. After the material is mixed in the mixing channel 4, the mixed material can be extruded through the extruder, and it can be extruded in a conical structure, which is a conventional technical means.

[0087] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
