[0001] The utility model belongs to the technical field of extraction devices, and particularly relates to an angelica dahurica coumarin extraction device. Background Technique

[0002] The angelica dahurica coumarin extraction device usually includes a high-pressure extraction tank and a related control system. The crushed angelica dahurica is put into the high-pressure extraction tank, and an appropriate amount of extraction solvent is added. Through the control system, the temperature, pressure, and extraction time are adjusted to make the solvent in the tank fully contact with the active ingredients such as coumarin in the angelica dahurica, so as to achieve effective extraction.

[0003] The patent with the patent announcement number CN110746436A discloses an extraction method of coumarin compounds in angelica dahurica and an angelica dahurica extract. The extraction method includes the following steps: carrying out hydrothermal extraction of angelica dahurica powder and water in a closed extraction container at a temperature above 100°C. The extraction method of coumarin compounds in angelica dahurica of the present invention utilizes the high-temperature and high-pressure environment in a closed hydrothermal kettle, and can extract the coumarin compounds in angelica dahurica to the greatest extent, with high efficiency, simplicity, economy, environmental protection, and high yield of active ingredients.

[0004] However, the current extraction device has the following problems: before extracting angelica dahurica coumarin, the angelica dahurica is not crushed, which may cause the extraction solvent to not fully penetrate into the plant tissue, and it takes longer time or more solvent to achieve the same extraction amount, thus wasting time and increasing costs. Therefore, we propose an angelica dahurica coumarin extraction device. Content of the Utility Model

[0005] The purpose of the utility model is to provide an angelica dahurica coumarin extraction device, which can solve the problem in the related technology that before extracting angelica dahurica coumarin, the angelica dahurica is not crushed, which may cause the extraction solvent to not fully penetrate into the plant tissue, and it takes longer time or more solvent to achieve the same extraction amount, thus wasting time and increasing costs.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] An angelica dahurica coumarin extraction device includes a base. A extraction box is fixedly connected to the top of the base. A discharge port is opened on the side of the extraction box. A guide plate is fixedly connected to the inner wall top of the extraction box. A crushing device is arranged on the side of the extraction box. The crushing device includes a double-shaft drive box. The side of the double-shaft drive box is fixedly connected to the side of the extraction box. Both output shafts of the double-shaft drive box are fixedly connected with rotating shafts. Crushing rollers are fixedly connected to the circumferential surface of the rotating shafts. A plurality of crushing blocks are fixedly connected to the circumferential surface of the crushing rollers.

[0008] On the inner wall of one side of the extraction box adjacent to the double-shaft drive box, there is a ring block fixedly connected. On the side surface of the ring block, there are several convex balls fixedly connected. On one side of the double-shaft drive box, one of the crushing rollers is fixedly connected with a contact block. Between one side of the crushing roller away from the double-shaft drive box and the inner wall of the extraction box, there is a spring.

[0009] Several of the convex balls are located on the displacement trajectory of the contact block. The rotating shaft is located at the central position of the ring block. The two ring blocks are arranged in a staggered manner.

[0010] On one side of the spring of the crushing roller, there is a blanking auxiliary device. The blanking auxiliary device includes a round block. The side surface of the round block is located on one side of the spring of the crushing roller. The inner wall of the extraction box is fixedly connected with an elastic telescopic rod. The end of the elastic telescopic rod away from the inner wall of the extraction box is rotatably connected with a struck block. On the side surface of the struck block, there is an arc-shaped knocking block fixedly connected. Between the struck block and the extraction box, there is a torsion spring. On the top of the diversion plate, there are several spacer plates fixedly connected.

[0011] The side surface of the struck block is in contact with the side surface of the crushing roller. The struck block is located on the displacement trajectory of the round block.

[0012] The top of the arc-shaped knocking block is in contact with the bottom of the diversion plate. The two elastic telescopic rods are arranged in a staggered manner.

[0013] The technical effects achieved by the present utility model are as follows:

[0014] Through the setting of the crushing device in the present utility model, the cooperation of the double-shaft drive box, the rotating shaft, the crushing roller, and the crushing blocks enables the rotation of the crushing roller to drive the crushing blocks to rotate. During the rotation of several crushing blocks, the angelica dahurica will be broken, and the broken angelica dahurica can release active ingredients into the solvent faster, accelerating the speed of the extraction process, thereby saving time and cost. At the same time, through the cooperation of the ring block, the convex balls, the contact block, the spring, and the diversion plate, the spring will drive the entire crushing roller to reset, and so on, so that the crushing roller moves reciprocally during the crushing process. Since the ring blocks and springs of the two crushing rollers are arranged in a staggered manner, the two crushing rollers move in opposite directions, which can increase the contact frequency and area between the angelica dahurica sample and the two crushing rollers, thereby improving the overall crushing efficiency.

[0015] Through the setting of the blanking auxiliary device in the present utility model, the cooperation of the elastic telescopic rod, the struck block, the arc-shaped knocking block, the round block, and the torsion spring enables the reset of the struck block to drive the arc-shaped knocking block to knock on the diversion plate, so that the angelica dahurica blocked by the spacer plates on the surface of the diversion plate slides from the surface of the diversion plate into the crushing device, thus avoiding the problem that countless angelica dahurica slide into the crushing device from the surface of the diversion plate at once, resulting in the jamming of the crushing roller.

[0024] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0025] As Figures 1-6 shown, a device for extracting angelicin is provided, which includes a base 1. A extraction box 2 is fixedly connected to the top of the base 1. A discharge port 3 is opened on the side of the extraction box 2. A deflector 4 is fixedly connected to the inner - wall top of the extraction box 2. A crushing device 5 is arranged on the side of the extraction box 2. The crushing device 5 includes a double - shaft drive box 51. The side of the double - shaft drive box 51 is fixedly connected to the side of the extraction box 2. Both output shafts of the double - shaft drive box 51 are fixedly connected with a rotating shaft 52. The circumferential surface of the rotating shaft 52 is fixedly connected with a crushing roller 53. A plurality of crushing blocks 54 are fixedly connected to the circumferential surface of the crushing roller 53.

[0026] On the inner wall on one side of the extraction box 2, there is a ring block 55 fixedly connected. On the side of the ring block 55, there are several convex balls 56 fixedly connected. One of the crushing rollers 53 is fixedly connected with a contact block 57 on one side of the double-shaft drive box 51. Between one side of the crushing roller 53 away from the double-shaft drive box 51 and the inner wall of the extraction box 2, there is a spring 58.

[0027] Several convex balls 56 are on the displacement track of the contact block 57. The rotating shaft 52 is at the central position of the ring block 55. The two ring blocks 55 are arranged in a staggered manner.

[0028] According to the above structure, when starting to extract angelicin, send the angelica dahurica to the surface of the diversion plate 4, and enter the interior of the extraction box 2 from the surface of the diversion plate 4. Start the double-shaft drive box 51. The two output shafts of the double-shaft drive box 51 drive their respective rotating shafts 52 to rotate towards each other. The rotation of the rotating shaft 52 will drive the crushing roller 53 to rotate. The rotation of the crushing roller 53 will drive the crushing blocks 54 to rotate. During the rotation of several crushing blocks 54, the angelica dahurica will be broken up. The broken angelica dahurica can release active ingredients into the solvent faster, accelerating the speed of the extraction process, thus saving time and cost. Among them, when the crushing roller 53 rotates, it also drives the contact block 57 to move. The contact block 57 will contact the convex balls 56 on the surface of the ring block 55, so that the contact block 57 pushes the crushing roller 53 to squeeze the spring 58. When the contact block 57 does not contact the convex balls 56 on the surface of the ring block 55, the spring 58 will drive the whole crushing roller 53 to reset. In this way, the crushing roller 53 moves reciprocally during the crushing process. Because the ring blocks 55 and springs 58 of the two crushing rollers 53 are arranged in a staggered manner, the two crushing rollers 53 move in opposite directions, so that the contact frequency and area between the angelica dahurica sample and the two crushing rollers 53 can be increased, thus improving the overall crushing efficiency.

[0029] As Figures 1-6 shown, on one side of the spring 58 of the crushing roller 53, there is a blanking auxiliary device 6. The blanking auxiliary device 6 includes a round block 64. The side of the round block 64 is on one side of the crushing roller 53 where the spring 58 is located. The inner wall of the extraction box 2 is fixedly connected with an elastic telescopic rod 61. The end of the elastic telescopic rod 61 away from the inner wall of the extraction box 2 is rotatably connected with a struck block 62. On the side of the struck block 62, there is an arc-shaped knocking block 63 fixedly connected. Between the struck block 62 and the extraction box 2, there is a torsion spring 65. On the top of the diversion plate 4, there are several spacer plates 66 fixedly connected.

[0030] The side of the struck block 62 is in contact with the side of the crushing roller 53. The struck block 62 is on the displacement track of the round block 64.

[0031] The top of the arc-shaped knocking block 63 is in contact with the bottom of the diversion plate 4. The two elastic telescopic rods 61 are arranged in a staggered manner.

[0032] According to the above structure, during the rotation of the crushing roller 53, the round block 64 will be driven to rotate. The rotation of the round block 64 will touch the struck block 62, so that the struck block 62 rotates at one end of the elastic telescopic rod 61. The rotation of the struck block 62 will drive the arc-shaped knocking block 63 away from the discharge port 3. When the round block 64 rotates away from the struck block 62, the struck block 62 will be reset by the elastic force of the torsion spring 65. The reset of the struck block 62 will drive the arc-shaped knocking block 63 to knock on the guide plate 4, so that the angelica dahurica blocked by the spacer plate 66 on the surface of the guide plate 4 slides from the surface of the guide plate 4 into the crushing device 5, thus avoiding the problem that countless angelica dahurica slide from the surface of the guide plate 4 into the crushing device 5 at once, resulting in the jamming of the crushing roller 53.

[0033] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
