Technical Field
[0001] This utility model relates to the technical field of alcohol precipitation equipment, and specifically to a particulate alcohol precipitation equipment. Background Technology
[0002] Granular alcohol precipitation equipment is a commonly used device in the refining process of traditional Chinese medicine extracts. It is mainly used to remove impurities by ethanol precipitation. Its core principle is based on the difference in solubility of different components in the ethanol-water system. Its workflow is generally divided into mixing stage, precipitation stage, solid-liquid separation and ethanol recovery.
[0003] Existing alcohol precipitation equipment typically extracts the supernatant to remove the effective precipitate. However, the extraction of the supernatant may also extract a small amount of effective precipitate along with the precipitate. Furthermore, the effective precipitate removed from the equipment often contains a certain amount of ethanol, increasing the loss of raw materials during the use of the alcohol precipitation equipment. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to provide a particle alcohol precipitation device that can eliminate the need for supernatant extraction and avoid the removal of effective precipitates containing a large amount of ethanol, thereby greatly reducing the loss of raw materials during the use of the alcohol precipitation device.
[0005] To solve the above problems, this utility model provides a particle alcohol precipitation device, including: a storage cylinder, which is provided with a filter plate and a filter ring, and the filter ring is fixedly sleeved on the outer periphery of the filter plate. The adjacent filter holes of the filter plate are symmetrically inclined, and the holes of the filter ring are vertical circular holes. A driving mechanism is provided on the filter ring for driving the filter plate to slide inside the storage cylinder.
[0006] A soft ring is located on the bottom side of the filter ring and is fixedly connected to the filter plate. Its outer peripheral wall is in contact with the inner wall of the storage cylinder.
[0007] Preferably, the storage cylinder includes a cylinder body and a cylinder cap, wherein the bottom end of the cylinder cap is slidably inserted into the top opening of the cylinder body.
[0008] Preferably, a feed valve is fixedly installed through the outer peripheral wall at the top of the storage cylinder, and several electrically controlled valves are symmetrically fixedly installed on the outer peripheral wall at the bottom of the storage cylinder.
[0009] Preferably, the bottom of the inner cavity of the storage cylinder is frustum-shaped, and the bottom end of the feed inlet of the electrically controlled valve is coplanar with the inner bottom wall of the storage hole.
[0010] Preferably, the cross-section of the soft ring is L-shaped, and several elastic plates are fixedly mounted in a circular array on the bottom side of the soft ring, with each elastic plate being fixedly connected to the filter plate.
[0011] Preferably, the driving mechanism includes a threaded rod, which is vertically disposed at the axial position inside the storage cylinder, and the bottom of the threaded rod is threaded through the filter plate and rotatably connected to the storage cylinder. The top of the threaded rod is clearance-fitted with the inner wall of the storage cylinder. A driver is fixedly installed on the bottom side of the storage cylinder, and the driving end of the driver is fixedly connected to the bottom end of the threaded rod.
[0012] Preferably, the outer periphery of the threaded rod is provided with a plurality of guide rods in a circular array, and the bottom end of the guide rod slides through the filter plate and is fixedly connected to the inner wall of the storage cylinder.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, according to an embodiment of the present invention, a particle alcohol precipitation device is provided, including: a storage cylinder 1, which is provided with a filter plate 2 and a filter ring 3, and the filter ring 3 is fixedly sleeved on the outer periphery of the filter plate 2. The adjacent filter holes of the filter plate 2 are symmetrically inclined, and the holes of the filter ring 3 are vertical circular holes. A driving mechanism 4 is provided on it for driving the filter plate 2 to slide inside the storage cylinder 1.
[0029] The soft ring 5 is located on the bottom side of the filter ring 3 and is fixedly connected to the filter plate 2. Its outer peripheral wall is in contact with the inner wall of the storage cylinder 1.
[0030] In this embodiment, when using the improved particulate alcohol precipitation equipment, please refer to... Figure 1 , Figure 2 and Figure 3 The drive mechanism 4 drives the filter plate 2 to slide up and down rapidly inside the storage cylinder 1. When the filter plate 2 moves up, part of the raw material on the top side of the filter plate 2 passes through the filter holes of the filter plate 2 and passes over the filter plate 2. Meanwhile, the particulate impurities mixed in the raw material cannot pass through the filter holes and are intercepted on the top side of the filter plate 2. At the same time, another part of the raw material on the top side of the filter plate 2 passes through the holes of the filter ring 3 and pushes the soft ring 5 downward, thereby releasing the blockage of the holes and thus carrying the particulate impurities from the holes to the bottom of the filter plate 2.
[0031] Please refer to Figure 2 , Figure 3 and Figure 4 When the filter plate 2 moves down, the soft ring 5 is pushed by the raw material and adheres to the filter ring 3, automatically sealing the holes on the filter ring 3. At this time, the raw material passes through the filter holes and flows to the top of the filter plate 2, while the impurities in the raw material are intercepted below the filter plate 2.
[0032] When the extract precipitates from the raw material to form an effective precipitate, the effective precipitate is constrained and limited to the top of the filter plate 2 due to the interception of the filter plate 2, filter ring 3 and soft plate, and is isolated from particulate impurities. When the effective precipitate is removed from the raw material, the drive mechanism 4 drives the filter plate 2 to move slowly upward, thereby picking up the effective precipitate from the raw material. During this process, the filter plate 2 is intermittently driven to move rapidly downward a certain distance. The effective precipitate is pushed upward by the raw material flowing from bottom to top, so that the effective precipitate floats up, thus avoiding the effective precipitate clogging the holes of the filter plate 2 during the upward movement of the filter plate 2, which would affect the use of the device.
[0033] In summary, as the raw material passes through the filter holes of filter plate 2 and the holes of filter ring 3, the raw material is repeatedly agitated to accelerate the mixing of ethanol and water, and impurities are separated from the raw material simultaneously. Subsequently, when the effective precipitate is removed from the device, it can be scooped out from the ethanol and water mixture without extracting the supernatant and avoiding the removal of a large amount of ethanol from the effective precipitate, thereby greatly reducing the loss of raw materials during the use of the alcohol precipitation equipment.
[0034] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the storage cylinder 1 includes a cylinder body 11 and a cylinder cover 12, with the bottom end of the cylinder cover 12 slidably inserted into the top opening of the cylinder body 11;
[0035] In this embodiment, please refer to Figure 1 and Figure 2 As shown, after the effective precipitate is removed from the mixture of ethanol and water, the filter plate 2 and the effective precipitate can be exposed to the outside air by separating the cylinder 11 and the cylinder cover 12, so that the effective precipitate can be taken out from the filter plate 2 through the top opening of the cylinder 11.
[0036] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a feed valve 6 is fixedly installed through the outer peripheral wall at the top of the storage cylinder 1, and several electrically controlled valves 7 are symmetrically fixedly installed on the outer peripheral wall at the bottom of the storage cylinder 1.
[0037] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the feed valve 6 is connected to the external injection equipment through a pipeline. When using the device, the feed valve 6 is opened, and the external injection equipment can inject the raw material into the storage cylinder 1 through the feed valve 6.
[0038] Some of the electrically controlled valves 7 are connected to external ethanol injection equipment, external water injection equipment, and high-temperature steam injection equipment through the feed pipe, thereby meeting the particulate ethanol precipitation operation of the raw material in the storage tank 1. One of the electrically controlled valves 7 is connected to the discharge pipe. After the effective precipitate is removed from the raw material, the electrically controlled valve 7 is opened, and the waste raw material in the storage tank 1 can be discharged through the discharge pipe. The waste raw material is then introduced into the distillation system to recover ethanol through the discharge pipe.
[0039] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the bottom of the inner cavity of the storage cylinder 1 is frustum-shaped, and the bottom end of the feed inlet of the electrically controlled valve 7 is coplanar with the inner bottom wall of the storage hole;
[0040] In this embodiment, please refer to Figure 1 and Figure 2 As shown, when the waste material in the storage cylinder 1 is discharged from the storage cylinder 1, the waste material can slide directly into the electrically controlled valve 7 along the inclined inner wall at the bottom of the storage cylinder 1, so as to minimize the residue of waste material on the inner wall of the storage cylinder 1.
[0041] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4As shown, the cross-section of the soft ring 5 is L-shaped, and several elastic plates 8 are fixedly mounted in a circular array on the bottom side of the soft ring 5, and each elastic plate 8 is fixedly connected to the filter plate 2.
[0042] In this embodiment, please refer to Figure 2 and Figure 4 As shown, the elastic plate 8 enhances the elasticity of the soft ring 5. When effectively removing sediment through the filter plate 2 and filter ring 3, the elastic plate 8 supports the soft ring 5, ensuring that the soft ring 5 remains in close contact with the filter ring 3. This maintains the sealing strength of the filter ring 3's pores, allowing the raw material to slowly pass through the filter plate 2 through the filter holes. Furthermore, the deformation and bending of the elastic plate 8 will not affect the downward bending deformation of the soft ring 5 when the filter plate 2 moves upward rapidly.
[0043] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the drive mechanism 4 includes a threaded rod 41, which is vertically arranged at the axial position inside the storage cylinder 1. The bottom of the threaded rod 41 is threaded through the filter plate 2 and rotatably connected to the storage cylinder 1. The top of the threaded rod 41 is clearance-fitted with the inner wall of the storage cylinder 1. The driver 42 is fixedly installed on the bottom side of the storage cylinder 1, and the driving end of the driver 42 is fixedly connected to the bottom end of the threaded rod 41.
[0044] In this embodiment, please refer to Figure 2 and Figure 3 As shown, when the device is in use, the driver 42 starts and drives the threaded rod 41 to rotate in the forward or reverse direction (the driver 42 is mainly composed of the existing housing, servo motor and gear transmission mechanism), thereby pushing the filter plate 2 upward or downward through the rotating threaded rod 41. The device has a high degree of automation (a sealing ring is installed inside the cylinder wall of the storage cylinder 1 to seal the gap between the threaded rod 41 and the storage cylinder 1).
[0045] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the outer periphery of the threaded rod 41 is provided with a number of guide rods 43 in a circular array, and the bottom end of the guide rod 43 slides through the filter plate 2 and is fixedly connected to the inner wall of the storage cylinder 1.
[0046] In this embodiment, please refer to Figure 2 and Figure 3 As shown, during the rotation of the threaded rod 41, the filter plate 2 will not rotate with the threaded rod 41 due to the constraint and limitation of the guide rod 43 on the filter plate 2, and the movement trajectory of the filter plate 2 is constrained, so that the filter plate 2 slides in a linear up-down trajectory (a sealing ring is installed inside the plate wall of the filter plate 2 to seal the gap between the guide rod 43 and the filter plate 2).
[0047] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 , Figure 5 As shown, a push rod 44 is slidably mounted on the top of the guide rod 43, and the top of the push rod 44 is fixedly connected to the cylinder cover 12. A support plate 45 is fixedly sleeved on the outer periphery of the push rod 44, and the diameter of the support plate 45 is larger than the diameter of the guide rod 43.
[0048] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5 As shown, after the filter plate 2 removes the effective sediment from the raw material, during the upward movement, the filter plate 2 will come into contact with the support plate 45. Then, the push rod 44 replaces the guide rod 43 to continue to constrain and limit the filter plate 2. As the filter plate 2 continues to move upward, the push rod 44 can be pushed upward through the support plate, thereby pushing the cylinder cover 12 out of the top opening of the cylinder 11 until the top of the threaded rod 41 retracts into the filter plate 2. Thus, after the effective sediment is removed from the raw material, the cylinder cover 12 is automatically separated from the cylinder 11, which facilitates the removal of the effective sediment from the storage cylinder 1.
[0049] Working principle: When this improved granular alcohol precipitation equipment is in use, the filter plate 2 and filter ring 3 are driven by the driver 42 to slide up and down in the storage cylinder 1, thereby agitating the raw materials in the storage cylinder 1, accelerating the mixing rate of water and ethanol, and simultaneously intercepting impurities in the raw materials below the filter plate 2. After the effective substances in the raw materials precipitate, almost all of the effective precipitate falls on the filter plate 2, and only a very small amount of effective precipitate is located below the filter plate 2. Then, by moving the filter plate 2 and filter ring 3 upward, almost all of the effective precipitate can be scooped out from the material, and the cylinder cover 12 and cylinder body 11 are separated at the same time. At this time, the effective precipitate is located in the top opening of the cylinder body 11, so the effective precipitate can be directly taken out from the filter plate 2 through the top opening of the cylinder body 11.
[0050] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.
[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
