Description

Technical Field

[0001] This utility model relates to the technical field of seed water extract pretreatment equipment, specifically to a crushing and grinding equipment for seed water extract. Background Technology

[0002] In the process of extracting seeds by water, crushing and grinding are key steps affecting the extraction rate of active ingredients. In traditional processes, crushing and grinding equipment for seed materials (such as soybeans, coix seeds, and ginkgo) often suffers from the following technical defects, which restrict the efficiency of the water extraction process and the quality of the product.

[0003] Traditional equipment typically treats crushing and grinding as separate processes. The crushed material needs to be manually transferred to the grinding device, resulting in an unconnected process that can easily lead to material loss or contamination. At the same time, the crushing particle size is not well adapted to the grinding process, causing some large particles that are not fully crushed to directly enter the grinding stage, increasing the grinding load and reducing efficiency. In addition, the crushed material mostly relies on its own weight to fall into the grinding channel along the guide surface. However, when the crushed material is too light or its accumulation is insufficient to support its downward movement, some material remains on the guide surface and is not fully ground.

[0004] Therefore, it is necessary to provide a crushing and grinding device for seed water extract to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing and grinding device for seed water extract extraction, comprising:

[0007] A feed hopper is installed at the top of the convex top cover and communicates with the interior of the convex top cover. A plate valve is provided at the bottom of the feed hopper for controlling the feed rate of the feed hopper.

[0008] A crushing assembly is fixed inside the bottom of the convex top cover, and the crushing execution end of the crushing assembly extends downward into the screen cylinder and is adapted to the internal dimensions of the screen cylinder.

[0009] A grinding assembly is disposed inside the processing cylinder below the sieve cylinder and is used to grind the crushed seed fragments that meet the particle size requirements. The grinding assembly includes a moving grinding element and a fixed grinding element, and a grinding channel is formed between the moving grinding element and the fixed grinding element. A scraper is installed at the top of the moving grinding element. The moving grinding element drives the scraper to actively scrape the seed fragments at the top of the fixed grinding element into the grinding channel for grinding.

[0010] A collection device is installed below the grinding assembly and extends to the outside of the processing cylinder.

[0011] Preferably, the crushing component includes:

[0012] A support plate, wherein several connecting rods are uniformly fixed on the periphery of the support plate, and the connecting rods are fixedly connected to the inner wall of the convex top cover;

[0013] A crushing shaft is vertically rotatably mounted on the support plate and extends downward to the bottom of the screen cylinder. Several crushing blades are evenly distributed around the shaft body of the crushing shaft, and the length and installation position of the crushing blades are adapted to the specifications of the screen cylinder.

[0014] A first motor is mounted on the upper end of the support plate, and the output end of the first motor is coaxially connected to the upper end of the crushing shaft.

[0015] Preferably, a flow divider is installed on the upper end of the support plate. The flow divider covers the outside of the first motor and is fixedly connected to the support plate. The top of the flow divider has a conical structure.

[0016] Preferably, the top of the processing cylinder is coaxially provided with an annular step facing downwards, and the top of the screen cylinder is adapted to the annular step and extends outwards with an annular overlapping part, which overlaps with the annular step.

[0017] Preferably, the grinding assembly further includes:

[0018] A drive shaft is coaxially mounted at the lower end of the moving grinding element and passes through the collecting device and the processing cylinder, and is coaxially connected to the output end of the second motor.

[0019] The moving grinding part is a frustum-shaped structure. A threaded hole is coaxially opened at the top of the moving grinding part. A ring plate is coaxially arranged at the upper end of the threaded hole. Several scrapers are adapted to be arranged on the periphery of the ring plate and the upper end face of the fixed grinding part. The fixed grinding part is a cylindrical rotating body structure. The grinding channel is formed between its inner side and the moving grinding part.

[0020] A screw, the shank of which passes through the ring plate and connects to the threaded hole.

[0021] Preferably, the scraper is an arc-shaped plate with its arc surface facing the direction of rotation.

[0022] Preferably, a mounting groove is horizontally provided on one side of the straight section at the bottom of the feed hopper, and the plate valve is rotatably mounted on one side of the mounting groove via a pin.

[0023] Compared with the prior art, this utility model provides a crushing and grinding device for seed water extract extraction, which has the following beneficial effects:

[0024] In this invention, the crushing, screening, and grinding processes are integrated into the same processing cylinder. After the seeds are crushed by the crushing component, the qualified particle size fragments fall directly through the screen cylinder to the grinding component, eliminating the need for manual material transfer and avoiding material loss and pollution risks. At the same time, the crushing and grinding processes are continuously connected, reducing equipment downtime and improving production efficiency.

[0025] Meanwhile, the length and installation position of the crusher blade are precisely matched with the specifications of the screen cylinder (the distance between the end of the crusher blade and the inner wall of the screen cylinder, and the distance between the bottom of the crusher blade and the bottom wall of the screen cylinder are all less than the diameter of the screen hole). With the rotation of the crushing shaft, the seeds in the screen cylinder can be crushed in a full-area coverage, effectively avoiding the retention of large particles in the dead corners of the screen cylinder. At the same time, the diversion hood disperses the feed to the working area of ​​the crusher blade, further improving the crushing uniformity and efficiency.

[0026] In addition, a scraper is installed at the top of the moving grinding part of the grinding assembly. The rotation of the moving grinding part drives the scraper to actively scrape the seed fragments at the top of the fixed grinding part into the grinding channel, avoiding the problem of edge accumulation or dead corner residue caused by the gravity feeding of materials in traditional grinding devices.

[0032] Please see Figure 1-4This utility model provides a crushing and grinding device for extracting seed water extracts, including: a processing cylinder 1, a convex top cover 2 installed on the top of the processing cylinder 1, a sieve cylinder 4 pressed between the convex top cover 2 and the top of the processing cylinder 1, and the sieve cylinder 4 extending downward into the interior of the processing cylinder 1.

[0033] The feed hopper 3 is installed at the top of the convex top cover 2 and communicates with the interior of the convex top cover 2. The bottom of the feed hopper 3 is provided with a plate valve 8 for controlling the feed amount of the feed hopper 3.

[0034] The crushing component 5 is fixedly disposed at the bottom of the inner part of the convex top cover 2, and the crushing execution end of the crushing component 5 extends downward into the screen cylinder 4 and is adapted to the internal size of the screen cylinder 4.

[0035] The grinding assembly 6 is disposed inside the processing cylinder 1 below the sieve cylinder 4 and is used to grind the crushed seed fragments that meet the particle size requirements. The grinding assembly 6 includes a moving grinding element 61 and a fixed grinding element 62, and a grinding channel is formed between the moving grinding element 61 and the fixed grinding element 62. A scraper 64 is installed at the top of the moving grinding element 61. The moving grinding element 61 drives the scraper 64 to actively scrape the seed fragments at the top of the fixed grinding element 62 into the grinding channel for grinding.

[0036] A collection device 7 is installed below the grinding assembly 6 and extends to the outside of the processing cylinder 1, for collecting the ground seeds or connecting them to the next process.

[0037] It should be explained that during use, the seeds to be processed are placed in the feed hopper 3, and then the crushing component 5 and the grinding component 6 are started to rotate. After that, the control plate valve 8 is opened, allowing the seeds to fall into the crushing component 5 for crushing. When the seeds are crushed to a certain size, the seed fragments fall through the screen holes of the screen cylinder 4 to the top of the grinding component 6. Under their own gravity or the scraping action of the scraper 64, they fall into the grinding channel for grinding, thus avoiding the seed fragments being too large to enter the grinding channel, or the seed fragments accumulating in the dead corner at the top of the grinding component 6, causing incomplete grinding.

[0038] Furthermore, the crushing component 5 includes:

[0039] A support plate 51, on which several connecting rods 52 are uniformly fixed on its periphery, and the connecting rods 52 are fixedly connected to the inner wall of the convex top cover 2.

[0040] The crushing shaft 53 is vertically rotatably mounted on the support plate 51. The crushing shaft 53 extends downward to the bottom of the screen cylinder 4. Several crushing blades 54 are evenly distributed around the shaft body of the crushing shaft 53. The length and installation position of the crushing blades 54 are adapted to the specifications of the screen cylinder 4.

[0041] A first motor 55 is mounted on the upper end of the support plate 51, and the output end of the first motor 55 is coaxially connected to the upper end of the crushing shaft 53.

[0042] The crushing blades 54 are spirally and evenly distributed along the shaft of the crushing shaft 53 or evenly distributed along the axial direction. The length specifications and installation positions of the crushing blades 54 are compatible with the specifications of the screen cylinder 4. This means that the length of the crushing blades 54 and the lower limit installation position meet the following requirements: the distance between the end of the crushing blade 54 and the inner wall of the screen cylinder 4 is less than the diameter of the screen hole, and the distance between the bottom installation position of the crushing blade 54 and the bottom wall of the screen cylinder 4 is less than the diameter of the screen hole, so as to avoid the presence of seed fragments that do not meet the particle size specifications in the dead corner positions inside the screen cylinder 4.

[0043] It needs to be explained that when the seeds fall from the plate valve 8, they are crushed by the crushing component 5. The rotational crushing action of the crushing component 5 increases the irregular movement of the seed fragments, pushing the seed fragments of the correct particle size to fall through the sieve holes. Specifically, the first motor 55 is energized and rotates, driving the crushing shaft 53 and the crushing blade 54 to rotate and crush the seeds in the sieve cylinder 4 until the seed fragments of the correct particle size fall through the sieve holes to the grinding component 6.

[0044] Furthermore, a diverter 56 is installed on the upper end of the support plate 51. The diverter 56 covers the outside of the first motor 55 and is fixedly connected to the support plate 51. The top of the diverter 56 is a conical structure, which is used to divert the falling seeds.

[0045] Specifically, the falling seeds are diverted to the periphery by the diversion hood 56, so that the seeds falling to the crushing execution end are relatively dispersed, thereby improving the crushing efficiency.

[0046] Furthermore, the top of the processing cylinder 1 is coaxially provided with an annular step 11 facing downwards, and the top of the screen cylinder 4 is adapted to the annular step 11 and extends outwards to provide an annular overlapping part 41, which overlaps the annular step 11.

[0047] It should be explained that the convex top cover 2 is installed on the top of the processing cylinder 1 to press and limit the annular overlapping part 41. The operation is simple and the installation is convenient.

[0048] Furthermore, the grinding assembly 6 also includes:

[0049] A drive shaft 66 is coaxially mounted at the lower end of the moving grinding member 61 and passes through the collecting device 7 and the processing cylinder 1 and is coaxially connected to the output end of the second motor 67.

[0050] The moving grinding element 61 has a frustum-shaped structure. A threaded hole is coaxially opened at the top of the moving grinding element 61. An annular plate 63 is coaxially arranged at the upper end of the threaded hole. A plurality of scrapers 64 are adapted to the upper end face of the fixed grinding element 62 around the annular plate 63. The fixed grinding element 62 has a cylindrical rotating body structure. The grinding channel is formed between its inner side and the moving grinding element 61.

[0051] Screw 65, the shank of which passes through the ring plate 63 and connects to the threaded hole.

[0052] Specifically, the scraper 64 has the same angle as the upper end face of the grinding member 62 and extends to the inner wall of the processing cylinder 1.

[0053] It should be explained that during grinding, the second motor 67 is energized to drive the drive shaft 66 and the moving grinding part 61 to rotate, grinding the seed fragments that enter the grinding channel; at the same time, the moving grinding part 61 drives the scraper 64 to scrape the seed fragments that fall to the top of the fixed grinding part 62 into the grinding channel for grinding, so as to avoid the seed fragments remaining on the top of the grinding assembly 6, which would result in incomplete grinding.

[0054] Furthermore, the scraper 64 is an arc-shaped plate, with its arc surface facing the side of the rotation direction.

[0055] In some embodiments, the top end of the fixed grinding member 62 is a downward-sloping conical surface, which facilitates the scraper 64 to scrape and gather the seed fragments and bring them into the grinding channel; the bottom of the scraper 64 is provided with a rubber layer, so that the scraper 64 and the fixed grinding member 62 are in elastic contact, further reducing the seed fragment residue at the top end of the fixed grinding member 62.

[0056] Furthermore, a mounting groove 81 is horizontally opened on one side of the straight section at the bottom of the feed hopper 3. The plate valve 8 is rotatably mounted on one side of the mounting groove 81 via a pin 82. A handle is provided at the end of the plate valve 8 away from the pin 82. The handle is located on the outside of the feed hopper 3. The thickness of the plate valve 8 is less than the height of the mounting groove 81.

[0057] In other words, the feeding speed and feeding amount of the feed hopper 3 can be adjusted by rotating the plate valve 8 by holding the hand part.

[0058] In practice, the seeds to be processed are placed in the feed hopper 3, and then the crushing component 5 and the grinding component 6 are started to rotate. Then the control plate valve 8 is opened, allowing the seeds to fall into the crushing component 5 for crushing. When the seeds are crushed to a certain size, the seed fragments fall through the screen holes of the screen cylinder 4 to the top of the grinding component 6. Under their own gravity or the scraping action of the scraper 64, they fall into the grinding channel for grinding, thus avoiding the seed fragments being too large to enter the grinding channel, or the seed fragments accumulating in the dead corner at the top of the grinding component 6, which would cause incomplete grinding.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
