Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a reaction device for preparing silicon-carbon composite materials. Background Art

[0002] Silicon-carbon composite is a high-performance material that combines the high theoretical specific capacity of silicon with the good electrical conductivity of carbon and is suitable for negative electrode materials in lithium-ion batteries.

[0003] For example, Chinese patent CN206746536U discloses a reaction device for preparing silicon-carbon composite materials. First, the feed port at the top of the mixing system is opened, and silicon powder, carbon powder, and asphalt powder are added in sequence; then the motor is turned on, and the motor drives the stirring blade to rotate through the connecting rod to mix the materials evenly; then the heating resistance wire is energized to heat the heat transfer oil in the storage tank; after the temperature sensor B in the storage tank reaches the set temperature, the delivery pump is turned on and the valve opening is adjusted, and the heat transfer oil enters the interlayer from the storage tank through the pipeline; the heated asphalt begins to react with the carbon powder and silicon powder; and the reaction product is discharged from the discharge port.

[0004] Although this structure can stir and mix the materials, the materials will accumulate on the inner wall of the barrel. This structure makes it inconvenient to clean the attached materials, resulting in uneven material mixing. Therefore, we propose a reaction device for preparing silicon-carbon composite materials that can clean the materials attached to the inner wall of the barrel to make the materials more evenly mixed, thereby improving the preparation effect of silicon-carbon composite materials. Utility Model Content

[0005] The purpose of the present invention is to provide a reaction device for preparing a silicon-carbon composite material, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a reaction device for preparing silicon-carbon composite materials, comprising a barrel, a bracket fixedly installed on the bottom of the barrel, a thermometer fixedly installed on the top surface of the barrel, and a processing assembly arranged above the bracket, the processing assembly including a cleaning assembly arranged above the bracket, and a mixing assembly arranged inside the cleaning assembly.

[0007] Preferably, the cleaning assembly includes a mounting plate fixedly mounted on the top surface of the barrel, a motor fixedly mounted on the top surface of the mounting plate, a main rod fixedly mounted on the output end of the motor, a connecting rod fixedly mounted on the outer wall of the main rod, a retaining ring fixedly mounted on the outer wall of the connecting rod, a sleeve slidingly provided on the outer wall of the connecting rod, a scraper fixedly mounted on the outer wall of the sleeve, and a spring sleeved on the outer wall of the connecting rod.

[0008] Preferably, the mixing assembly includes a rotating rod rotatably connected to the inside of the connecting rod, a stirring rod is fixedly mounted on the outer wall of the rotating rod, a limiting ring is provided above the stirring rod, a gear is fixedly mounted on the end of the rotating rod, and the gear is meshed with a gear ring.

[0009] Preferably, there are four scrapers distributed around the center of the main rod. When the centrifugal force of the scrapers is the largest, the scrapers come into contact with the inner wall of the barrel to clean the inner wall of the barrel.

[0010] Preferably, one end of the spring is fixedly installed on the side of the retaining ring away from the main rod, and the end of the spring away from the retaining ring is fixedly installed on the end of the connecting rod away from the main rod. Under the elastic action of the spring, the scraper that is not affected by centrifugal force can be reset.

[0011] Preferably, there are eight limiting rings, which are divided into four groups and distributed crosswise with the center of the main rod. Under the restriction of the limiting rings, the rotating rod can be guaranteed to rotate stably inside the connecting rod.

[0012] Preferably, the gear ring is fixedly mounted on the inner top surface of the barrel, and the gear is meshed with the inner wall of the gear ring. When the gear rotates with the center of the main rod as the center of rotation, under the restriction of the meshing of the gear and the gear ring, the gear can drive the rotating rod to rotate accordingly, so as to improve the mixing effect of the raw materials.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The reaction device for preparing silicon-carbon composite materials is composed of a cleaning component as one of its components. When the silicon-carbon composite material needs to be prepared, the raw materials need to be mixed. The raw materials are added into the barrel, and the motor is started. The main rod fixedly installed at the output end begins to rotate, and the main rod drives the connecting rod fixedly installed on the outer wall to rotate accordingly. The connecting rod drives the collar mounted on the outer wall to rotate accordingly, and the scraper fixedly installed on the outer wall of the collar rotates accordingly. The raw materials inside the barrel can be mixed by the scraper. When the raw materials adhere to the inner wall of the barrel, the motor speed is adjusted to the maximum. Under the action of centrifugal force, the scraper is swung toward the inner wall of the barrel, so that the collar fixed on the outer wall of the scraper slides on the outer wall of the connecting rod. When the motor rotates at a low speed, the spring pushes the sleeve so that the scraper no longer contacts the inner wall of the barrel, and the raw materials can be stirred. When the mixing is completed, the motor stops working and the scraper no longer rotates. Under the action of the spring, the sleeve is pushed toward the retaining ring, causing the sleeve to collide with the retaining ring to generate vibration, thereby shaking off the raw materials attached to the outer wall of the scraper (the barrel, bracket, thermometer, and preparation structure are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0015] 2. The reaction device for preparing silicon-carbon composite materials is composed of a mixing component as one component. When preparing silicon-carbon composite materials, it is necessary to stir and mix the raw materials. The motor is started to rotate the main rod, and the main rod drives the connecting rod to rotate. The rotating rod connected to the connecting rod rotates, and the stirring rod fixedly installed on the outer wall of the rotating rod rotates with the center of the main rod as the center of rotation to stir and mix the raw materials. When the rotating rod rotates, the gear fixedly installed on its end rotates accordingly. Since the gear is engaged with the gear ring on the top surface of the barrel, the gear rotates under its restriction, and the gear drives the rotating rod to rotate by itself. The rotating rod drives the stirring rod fixed on its outer wall to rotate accordingly to evenly mix the raw materials. This structure enables the rotating rod and the stirring rod to rotate and stir with the center of the main rod as the center of rotation. At the same time, the rotating rod and the stirring rod can rotate by themselves, thereby improving the stirring effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings. Example 1

[0024] A preferred embodiment of a reaction device for preparing a silicon-carbon composite material provided by the utility model is as follows Figures 1 to 6 Shown: A reaction device for preparing a silicon-carbon composite material, comprising a barrel 1;

[0025] A bracket 2 is fixedly installed at the bottom of the barrel 1;

[0026] A temperature detector 3 is fixedly installed on the top surface of the barrel 1;

[0027] And a processing component 4 is arranged above the bracket 2, the processing component 4 includes a cleaning component 41 arranged above the bracket 2, the cleaning component 41 includes a mounting plate 411 fixedly mounted on the top surface of the barrel 1, a motor 412 is fixedly mounted on the top surface of the mounting plate 411, a main rod 413 is fixedly mounted on the output end of the motor 412, a connecting rod 414 is fixedly mounted on the outer wall of the main rod 413, a retaining ring 415 is fixedly mounted on the outer wall of the connecting rod 414, a ring 416 is slidingly arranged on the outer wall of the connecting rod 414, a scraper 417 is fixedly mounted on the outer wall of the ring 416, and a spring 418 is sleeved on the outer wall of the connecting rod 414.

[0028] In this embodiment, when it is necessary to prepare the silicon-carbon composite material, the raw materials need to be mixed, the raw materials are added to the inside of the barrel 1, the motor 412 is started, and the main rod 413 fixedly installed at its output end begins to rotate, and the main rod 413 drives the connecting rod 414 fixedly installed on its outer wall to rotate accordingly, and the connecting rod 414 drives the ring 416 sleeved on its outer wall to rotate accordingly, and the scraper 417 fixedly installed on the outer wall of the ring 416 rotates accordingly, and the raw materials inside the barrel 1 can be mixed by the scraper 417. When the raw materials adhere to the inner wall of the barrel 1, the speed of the motor 412 is adjusted to the maximum at this time, and under the action of centrifugal force, the scraper 417 is swung toward the inner wall of the barrel 1, so that the ring 416 fixedly installed on the outer wall of the scraper 417 slides on the outer wall of the connecting rod 414, and the spring 416 sleeved on the outer wall of the connecting rod 414 is pressed. 18 compression, when the rotating scraper 417 contacts the inner wall of the barrel 1, the scraper 417 can clean the inner wall of the barrel 1 to prevent the raw materials from adhering to the inside of the barrel 1. When the speed of the motor 412 is relatively low, the spring 418 elastically pushes the sleeve 416 so that the scraper 417 no longer contacts the inner wall of the barrel 1, and the raw materials can be stirred. When the mixing is completed, the motor 412 no longer works, and the scraper 417 no longer rotates. The spring 418 elastically pushes the sleeve 416 toward the retaining ring 415, so that the sleeve 416 collides with the retaining ring 415 to generate vibration, thereby shaking off the raw materials attached to the outer wall of the scraper 417 (the barrel 1, the bracket 2, the thermometer 3, and the preparation structure are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0029] Furthermore, there are four scrapers 417 distributed around the center of the main rod 413. When the centrifugal force of the scrapers 417 is the largest, the scrapers 417 contact the inner wall of the barrel 1 and clean the inner wall of the barrel 1.

[0030] Furthermore, one end of the spring 418 is fixedly installed on the side of the retaining ring 415 away from the main rod 413, and the other end of the spring 418 away from the retaining ring 415 is fixedly installed on the end of the connecting rod 414 away from the main rod 413. Under the elastic action of the spring 418, the scraper 417 that is not affected by centrifugal force can be reset. Example 2

[0031] On the basis of Example 1, a preferred embodiment of a reaction device for preparing a silicon-carbon composite material provided by the present invention is as follows: Figures 1 to 6 As shown: the mixing assembly 42 includes a rotating rod 421 rotatably connected to the inside of the connecting rod 414, a stirring rod 422 is fixedly installed on the outer wall of the rotating rod 421, a limiting ring 423 is provided above the stirring rod 422, and a gear 424 is fixedly installed on the end of the rotating rod 421, and the gear 424 is engaged with a gear ring 425.

[0032] When the gear 424 is engaged with the gear ring 425 on the top surface of the barrel 1, the gear 424 rotates under the restriction of the gear 424, and the gear 424 drives the rotating rod 421 to rotate by itself, and the rotating rod 421 drives the stirring rod 422 fixed on its outer wall to rotate to mix the raw materials evenly.

[0033] Furthermore, there are eight limiting rings 423 , which are divided into four groups and are cross-distributed with the main rod 413 as the center. Under the restriction of the limiting rings 423 , the rotating rod 421 can be ensured to rotate stably inside the connecting rod 414 .

[0034] In addition, the ring gear 425 is fixedly installed on the top surface of the inner part of the barrel 1, and the gear 424 is engaged with the inner wall of the ring gear 425. When the gear 424 rotates with the center of the main rod 413 as the rotation center, under the engagement limit of the gear 424 and the ring gear 425, the gear 424 can drive the rotating rod 421 to rotate accordingly, so as to improve the mixing effect of the raw materials.

[0035] The above is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention. It should also be noted that the various components of the present invention are not limited to the above-mentioned overall application.
