Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, in particular to filtering and extracting equipment and a production method for natural quality bezoar. Background Art

[0002] The purification of bezoar is an important process in the production of bezoar. The common bezoar purification process mainly includes raw material preparation, cleaning, preliminary crushing, dissolution filtration, secondary filtration and drying and solidification. Dissolution filtration is to dissolve bezoar in a solvent (such as warm water or ethanol), and then filter the solvent through an ultrafiltration device. The ultrafiltration device mainly uses ultrafiltration membrane filaments as filter media to intercept macromolecular substances in the bezoar solvent. However, there are certain deficiencies in practical applications: since bezoar needs to be crushed, in addition to common macromolecular substances, there are inevitably a small amount of bezoar particles that have not been completely crushed before in the bezoar solvent. On the one hand, the volume of bezoar particles is larger than that of ordinary impurities, and the inner diameter of the ultrafiltration membrane filaments in the ultrafiltration equipment is small, which makes the ultrafiltration membrane filaments easily blocked, thereby affecting the filtration efficiency. Secondly, bezoar is of high value, and these small amounts of bezoar particles still contain undissolved effective ingredients. If they are removed together with other filtered impurities, it will cause certain losses. Summary of the invention

[0018] Compared with the prior art, the present invention provides a filtering and extraction device and a production method for natural quality bezoar, which has the following beneficial effects:

[0019] 1. The filtering and extracting equipment and the production method for natural quality bezoar are characterized in that a collecting cylinder, a metal sieve plate, a vertical drive assembly, a grinding assembly and an infusion assembly are arranged at the water inlet end of an ultrafilter, so that larger bezoar particles in a bezoar solvent are intercepted and collected in advance, and then ground and crushed and mixed with a dissolving liquid, and finally discharged into a filter of the ultrafilter.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a filtering and extraction device and a production method for natural quality bezoar.

[0035] Example 1: Please refer to Figure 1-Figure 4 , a filtering and extracting device, comprising an ultrafilter 1, the ultrafilter 1 is provided with a filter 2 and a water inlet pipe 3, the end of the water inlet pipe 3 is fixedly connected with a collecting cylinder 4, the bottom of the collecting cylinder 4 is fixedly connected to the end of the water inlet pipe 3, the top of the collecting cylinder 4 is fixedly connected with an input pipe 5, a metal sieve plate 6 is provided inside the collecting cylinder 4, the metal sieve plate 6 is used to filter the bezoar particles in the bezoar solvent, the collecting cylinder 4 is also equipped with a vertical drive assembly 7 and a grinding assembly 8, and the ultrafilter 1 is also equipped with an infusion assembly 9;

[0036] The vertical drive assembly 7 comprises a cylinder 71 fixed on the top wall of the collecting cylinder 4, and the vertical drive assembly 7 is used to drive the metal sieve plate 6 to move vertically;

[0037] The grinding assembly 8 includes a rotatable pressure rod 81 installed in the collecting tube 4, and the pressure rod 81 is located above the metal sieve plate 6. The grinding assembly 8 is used to grind the bezoar particles and stir the liquid in the collecting tube 4;

[0038] The infusion assembly 9 includes a water tank 91 fixed on the ultrafiltration machine 1, and a delivery tube 92 is connected between the water tank 91 and the collection tube 4;

[0039] When the ultrafilter 1 is initially filtered, the metal sieve plate 6 intercepts the bezoar particles in the bezoar solvent entering the filter 2 in advance. After the ultrafilter 1 is initially filtered, the vertical drive assembly 7 is operated to force the metal sieve plate 6 to move up to the fitting pressure rod 81, and the grinding assembly 8 is operated to force the pressure rod 81 to rotate, and the bezoar particles on the metal sieve plate 6 are ground. After grinding, the infusion assembly 9 is operated to transport the dissolved liquid into the collecting tube 4, and the ground bezoar components are mixed with the dissolved liquid and then injected into the filter 2;

[0040] Wherein, the collecting tube 4 is set as a hollow cylindrical shell, the end of the water inlet pipe 3 is fixed to the bottom center of the collecting tube 4, an electromagnetic valve is arranged on the input pipe 5, and in actual application, the input pipe 5 is connected to the delivery system of the bezoar solvent, the metal sieve plate 6 is set as a circular stainless steel plate, and the surface is provided with evenly distributed sieve holes, the diameter of the metal sieve plate 6 is the same as the inner diameter of the collecting tube 4, and a rubber ring is fixed on the outer edge of the metal sieve plate 6 to achieve a close fit with the inner wall of the collecting tube 4, and the inside of the water tank 91 is pre-filled with a dissolving liquid, such as warm water or ethanol;

[0041] When in use, the bezoar solvent first passes through the input pipe 5, the collecting barrel 4 and the water inlet pipe 3 in sequence before entering the filter 2, and a small amount of solid bezoar particles in the bezoar solvent are retained by the metal sieve plate 6, thereby preventing the bezoar particles from blocking the filter thread in the filter 2, after the bezoar solvent is initially filtered, only the moist bezoar particles attached to the metal sieve plate 6 are left in the collecting barrel 4, and then the vertical drive assembly 7 is started, and the vertical drive assembly 7 drives the metal sieve plate 6 to move vertically upward by the cylinder 71 after the operation, so that the top of the metal sieve plate 6 fits the pressure bar 81 above, and then the grinding assembly 8 is operated, forcing the pressure bar 81 to rotate slowly, squeezing the bezoar particles on the metal sieve plate 6, and breaking them, and then starting the infusion assembly 9, when the infusion assembly 9 is in operation, the dissolved liquid in the water tank 91 is transported to the collecting barrel 4, and the effective ingredient in the bezoar after the previous crushing is dissolved in the dissolved liquid to form a solvent, and then discharged into the filter 2 together with the bezoar solvent that needs secondary filtration for further filtration;

[0042] By arranging a collecting cylinder 4, a metal sieve plate 6, a vertical drive component 7, a grinding component 8 and an infusion component 9 at the water inlet end of the ultrafilter 1, larger bezoar particles in the bezoar solvent are intercepted and collected in advance, and then ground and crushed and mixed with the dissolving liquid, and finally discharged into the filter 2 of the ultrafilter 1. In this way, larger bezoar particles can be prevented from entering the filter 2 and directly clogging the filter wire, thereby ensuring the filtering effect of the filter 2. At the same time, this part of the bezoar particles can be treated separately and then filtered, so that the effective ingredients in the bezoar particles can be fully utilized, compared with the prior art, the loss is reduced, the utilization rate of the raw materials is improved, and the bezoar extraction rate is thereby improved.

[0043] Example 2: See Figure 4-Figure 7, which is different from the above embodiment, the output end of the cylinder 71 is vertically downward and extends into the collecting tube 4, a vertical shaft 72 is fixed to the output end of the cylinder 71, the metal screen plate 6 is installed on the vertical shaft 72, the grinding assembly 8 also includes a fixing ring 82 fixed to the inner top wall of the collecting tube 4 and a first motor 83 fixed to the top of the collecting tube 4, an outer sleeve 84 is rotatably connected in the fixing ring 82, a driven gear 85 is fixedly sleeved on the outer wall of the outer sleeve 84, the output shaft of the first motor 83 extends to the inside of the collecting tube 4 and a driving gear 86 is fixed, the driving gear 86 is meshed with the driven gear 85, an inner sleeve 87 is also installed in the outer sleeve 84, the bottom end of the inner sleeve 87 extends to the outside of the outer sleeve 84, one end of the pressure rod 81 is fixedly connected to the outer wall of the inner sleeve 87, and the bottom edge of the pressure rod 81 is provided with a chamfer;

[0044] Among them, the number of the pressure rods 81 is set to at least two, and the two pressure rods 81 are distributed in a ring array. The first motor 83 is set to a servo motor. When in use, the cylinder 71 is started, and the cylinder 71 contracts to drive the vertical shaft 72 to move upward. When the vertical shaft 72 moves upward, it drives the metal screen plate 6 to move upward until the metal screen plate 6 contacts the bottom of the pressure rod 81, and then the first motor 83 is started. When the first motor 83 is running, it drives the driving gear 86 to rotate, and when the driving gear 86 rotates, it drives the driven gear 85 to rotate, and when the driven gear 85 rotates, it drives the outer sleeve 84 to rotate, and when the outer sleeve 84 rotates, it drives the inner sleeve 87 and the pressure rod 81 to rotate. When the pressure rod 81 rotates, the bezoar particles enter the area between the chamfer on the pressure rod 81 and the metal screen plate 6, and are then squeezed and crushed by the pressure rod 81;

[0045] The metal sieve plate 6 is driven to move vertically by the cylinder 71, and the pressure rod 81 is driven to rotate by the first motor 83, which is conducive to automatically grinding the bezoar particles on the top of the metal sieve plate 6 and facilitates the subsequent reuse of the bezoar particles.

[0046] Example 3, see Figure 4 and Figure 5 , which is different from the above embodiment, the inner sleeve 87 is slidably connected to the outer sleeve 84, a vertical spring 88 is fixedly connected between the top of the inner sleeve 87 and the inner wall of the outer sleeve 84, and the outer sleeve 84, the inner sleeve 87 and the vertical spring 88 are all sleeved outside the output shaft of the cylinder 71;

[0047] The inner wall of the outer sleeve 84 is provided with a vertical slide groove, and the outer wall of the inner sleeve 87 is provided with a vertical slider. The vertical slider and the vertical slide groove are used to realize sliding connection, and when the outer sleeve 84 rotates, the inner sleeve 87 can also be driven to rotate. By setting a vertical spring 88, the actual application is that the cylinder 71 drives the metal screen plate 6 to move upward, and when the metal screen plate 6 contacts the pressure rod 81, it continues to move upward for a certain height, thereby driving the pressure rod 81 and the inner sleeve 87 to move upward, so that the vertical spring 88 is compressed. At this time, the elastic force of the vertical spring 88 makes the pressure rod 81 fit tightly on the metal screen plate 6;

[0048] By providing the vertical spring 88, the pressure rod 81 can be closely fitted to the metal sieve plate 6, thereby improving the grinding effect.

[0049] Example 4, see Figure 6 , which is different from the above embodiment, a rubber plug 73 is fixedly connected to the bottom end of the vertical shaft 72, and the rubber plug 73 is located just above the end of the water inlet pipe 3. The rubber plug 73 is set in a truncated cone shape. One end of the delivery pipe 92 penetrates into the water tank 91 and is fixedly connected to the water tank 91. The other end of the delivery pipe 92 penetrates the top wall of the collection cylinder 4 and extends into the collection cylinder 4. The delivery pipe 92 is located inside the collection cylinder 4 and is fixedly connected to a nozzle 93 at one end. A water pump 94 is fixedly connected to the inside of the water tank 91. The output end of the water pump 94 is fixed to the end of the delivery pipe 92. A valve 95 is also provided at one end of the delivery pipe 92 close to the collection cylinder 4.

[0050] Among them, the height of the nozzle 93 is higher than the height of the pressure rod 81. When in use, after the bezoar particles are ground, the cylinder 71 is first controlled to extend. The extension of the cylinder 71 drives the vertical shaft 72, the metal sieve plate 6, and the rubber plug 73 to move downward. The side of the rubber plug 73 tightly abuts against the end of the water inlet pipe 3 to block the water inlet pipe 3, and then the water pump 94 is started. After the water pump 94 is running, the dissolved liquid in the water tank 91 is transported to the delivery pipe 92, and then sprayed into the collecting tube 4 through the nozzle 93. The dissolved liquid entering the collecting tube 4 contacts with the effective ingredients in the bezoar and then fuses. At this time, the grinding assembly 8 can also be started. When the grinding assembly 8 is running, it drives the pressure rod 81 in the collecting tube 4 to rotate, which can play a stirring role and accelerate the fusion process.

[0051] By providing the rubber plug 73, the water inlet pipe 3 can be blocked before injecting the dissolved liquid into the collecting tube 4, so that the dissolved liquid can be retained first after entering the collecting tube 4. At the same time, the dissolved liquid in the collecting tube 4 is stirred in cooperation with the grinding component 8, so that the dissolved liquid can be fully integrated with the effective ingredients in the bezoar, thereby improving the utilization rate of the bezoar and further improving the extraction rate of the effective ingredients in the bezoar.

[0052] Example 5, see Figure 7-Figure 9, which is different from the above embodiment, a vertical tube 61 is fixed at the center of the metal sieve plate 6, and the vertical tube 61 is rotatably connected to the vertical shaft 72. A second bevel gear 62 is fixedly sleeved at the bottom end of the vertical tube 61, and a through slot 63 is also provided on the outer wall of the vertical tube 61. A ratchet gear 721 is fixed on the vertical shaft 72, and the ratchet gear 721 corresponds to the position of the through slot 63. A base block 64 is fixed on the top of the second bevel gear 62, and a transverse spring 65 is fixedly connected to one side of the base block 64. A clamping rod 66 is fixed at one end of the transverse spring 65 away from the base block 64, and one end of the clamping rod 66 is inserted into the through slot 63. A ratchet block 661 is provided at one end of the clamping rod 66 located inside the through slot 63, and the clamping rod 66 is meshed with the ratchet gear 721 through the ratchet block 661;

[0053] Among them, the metal sieve plate 6 is installed by the engagement of the clamping rod 66 and the ratchet block 661. In actual application, the friction force of the pressure rod 81 on the metal sieve plate 6 during the rotation process makes the metal sieve plate 6 have a rotation tendency in the same direction as the pressure rod 81, but due to the engagement of the clamping rod 66 and the ratchet gear 721, the metal sieve plate 6 cannot rotate at this time and always remains stationary during the grinding process.

[0054] Example 6, see Figure 7 and Figure 8 , which is different from the above embodiment, the side wall of the collecting cylinder 4 is fixedly connected with a second motor 10, the output shaft of the second motor 10 is fixed with a horizontal shaft 11, the horizontal shaft 11 penetrates into the inside of the collecting cylinder 4, the horizontal shaft 11 is installed on the inner bottom wall of the collecting cylinder 4 through a bearing seat 12, the end of the horizontal shaft 11 is fixed with a first bevel gear 13, and the second bevel gear 62 corresponds to the first bevel gear 13 in position;

[0055] Among them, the second bevel gear 62 is located just below the edge of the first bevel gear 13. When the cylinder 71 drives the rubber plug 73 to move downward and block the water inlet pipe 3, the second bevel gear 62, which also moves downward, just moves downward to mesh with the first bevel gear 13. At this time, the second motor 10 is started. When the second motor 10 is running, it drives the first bevel gear 13 to rotate, and the first bevel gear 13 drives the second bevel gear 62 to rotate. When the second bevel gear 62 rotates, it drives the clamping rod 66 to move. At this time, the ratchet block 661 at the end of the clamping rod 66 is squeezed with the ratchet gear 721, so that the clamping rod 66 moves out of the through groove 63 and compresses the transverse spring 65, and then meshes with the ratchet gear 721 again under the elastic force of the transverse spring 65. That is, when the second motor 10 is running, it can drive the metal sieve plate 6 at this time to rotate. At the same time, the infusion component 9 is running to spray the dissolved liquid to various parts of the metal sieve plate 6;

[0056] The metal sieve plate 6 is installed by the ratchet gear 721 and the clamping rod 66, so that the metal sieve plate 6 can only rotate in one direction, thereby avoiding the rotation of the metal sieve plate 6 during grinding. When the dissolving liquid is injected, the metal sieve plate 6 can be driven to rotate by the second motor 10. The rotation of the metal sieve plate 6 enables the dissolving liquid to be sprayed on various positions on the metal sieve plate 6 through the nozzle 93, which is beneficial to flushing away the wet bezoar powder adhering to the surface of the metal sieve plate 6 after grinding, so that the ground bezoar can be more fully contacted and fused with the dissolving liquid, avoiding the loss caused by sticking, and further improving the utilization rate.

The method for producing natural quality bezoar mainly includes raw material preparation, cleaning treatment, preliminary crushing, dissolution and filtration, secondary filtration and drying and solidification, wherein a filtration and extraction equipment in the above embodiment is used in the dissolution and filtration step.
