[0002] Humic acid is a macromolecular organic substance widely found in nature, and is widely used in agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine and health, environmental protection and other fields. Some low calorific value coals, such as peat, lignite and weathered coal, contain 10-80% humic acid. my country's coal is rich in humic acid, so the production and application of humic acid in my country can also be said to be an aspect of coal chemical industry.

[0003] Prior art, such as a device for extracting humic acid from weathered coal disclosed in CN106432751B, requires a crushing structure to crush the weathered coal, then the weathered coal is processed by an acid-base reactor to separate the humic acid, and then the raw materials are concentrated by a concentration device, and then washed after concentration. The existing processing process requires the use of multiple groups of reaction structures for processing, resulting in an overall large structure of the equipment and high cost.

[0004] Moreover, the crushers in the prior art are usually large in size, and there will be many large fragments during the crushing process. During the humic acid extraction process, the solvent needs to be fully in contact with the weathered coal. The large fragments have a small contact area, which will affect the extraction effect. During the extraction process, the large fragments are also easy to damage the mixing mechanism, and are easy to get stuck between the mixing mechanism and the inside of the reactor, causing damage to the inner wall of the reactor.

[0046] When the present invention is used, the reactor 1 is first connected to an external power source so that the reactor can operate normally. Then, the liquid (extraction solvent) is injected into the reactor 1 through the liquid feed pipe 104. Then, the weathered coal to be extracted is put into the block feed port 103. The block is controlled by the valve below so that the block can fall into the sleeve 3 until the block falls on the first filter screen 702. The larger block is intercepted by the first filter screen 702. At this time, the drive motor 2 is started, and the drive motor 2 drives the transmission rod 202 to rotate. The transmission rod 202 drives the multiple sets of transmission gears 107 to rotate through the outer gear ring 203 on the outside. The transmission gear 107 The sleeve 3 is driven to rotate in the opposite direction to the driving rod 202, and the rotating block 701 is fixed on the outside of the driving rod 202, and the first crushing ring 703 is fixed on the inner wall of the sleeve 3, so that the rotating block 701 and the first crushing ring 703 rotate in the opposite direction, and there is a certain distance between the rotating block 701 and the first crushing ring 703, so that the block material can be crushed, and the grinding groove 7011 can further crush the larger coal blocks to improve the crushing efficiency. The crushed powder will fall through the distance and further pass through the sleeve 3 to fall onto the second crushing mechanism 8. The mesh size of the second filter 801 is further reduced, so that the powder can be further crushed. The powder that cannot be filtered will adhere to the second filter screen 801. At this time, the rotating gathering cylinder 4 will drive the gathering fan blades 401 to rotate, sucking the liquid from the top of the gathering cylinder 4, so that the liquid flows downward in the gathering cylinder 4. The flowing liquid will flush the second filter screen 801, so that the large pieces of powder attached to the top will slide downward with the liquid until they enter the clamping ring 204 and the second crushing ring 802. The clamping ring 204 is provided with a groove inside, and the inner wall of the second crushing ring 802 is provided with a protruding ring matching the groove. When rotating, more large pieces of powder that fall in can be ground and crushed, thereby improving the fineness of the powder and improving the The powder material passing through the second filter screen 801 will fall downwards and be in the middle of the plurality of diffusion blades 6. At this time, the diffusion blades 6 will rotate under the drive of the blade fixing frame 5, and throw the liquid material outwards, so that the powder material will flow upwards along the inner wall of the reactor until it moves to the vicinity of the bottom end of the gathering cylinder 4, and then is sucked into the gathering cylinder 4 by the rotating gathering blades 401, thus realizing the circulation stirring of the material and fully improving the mixing effect. In the circulation process, the powder material is driven to continuously pass through the second crushing mechanism 8, thereby continuously filtering and crushing the powder material, reducing the probability of powder material agglomeration and improving the reaction rate.
