Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine liquid extraction equipment, and in particular to an extraction equipment for a Chinese herbal medicine extract for promoting blood circulation and unblocking meridians. Background Art

[0002] Chinese herbal medicines for promoting blood circulation and unblocking meridians refer to a class of Chinese herbal medicines that have the effects of promoting blood circulation, promoting qi, relaxing muscles and unblocking meridians. They are often used to improve blood circulation, relieve pain, treat symptoms such as blood stasis. For example, a common decoction for promoting blood circulation and removing stasis is available on the market. The decoction for promoting blood circulation and removing stasis is a commonly used Chinese medicine prescription, which is mainly used to promote blood circulation and remove stasis, improve blood circulation, and is suitable for various diseases caused by qi stagnation and blood stasis, such as pain, blood stasis, irregular menstruation, etc.

[0003] At present, in the process of extracting and preparing Huoxue Huayu Decoction, a filter is needed to remove solid impurities in the Huoxue Huayu Decoction extract liquid to ensure that the obtained extract is clear. However, the existing filters for Chinese herbal medicine extracts have the following disadvantages during use:

[0004] Although the filter cylinder arranged inside the filter can filter out impurities in the extract of the blood-activating and stasis-removing soup, the intercepted impurities generally accumulate on the inner surface of the filter cylinder and, under the action of gravity, may accumulate at the bottom of the filter cylinder, which will cause the filter holes of the filter cylinder to be blocked, causing the filtration permeability to deteriorate and greatly reduce the filtration efficiency. Therefore, the present application provides an extraction device for the blood-activating and stasis-removing Chinese herbal extract to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an extraction device for Chinese herbal medicine extract for promoting blood circulation and unblocking meridians. By setting a hydraulic scraper, the device can use the impact of an external liquid pump device to transport the Chinese herbal medicine extract into the flow cavity through the liquid inlet pipe and the inflow channel to scrape the impurities intercepted on the inner wall of the filter cylinder. Based on the application of the hydraulic scraper, the transmission part can be linked to the setting of the transmission part to realize the synchronous reciprocating up and down vibration of the filter cylinder in the filter tank. At the same time, under the setting of the limit buffer part, the force dropped when the filter cylinder reciprocates up and down can be buffered, so as to solve the problem that the filter cylinder in the existing filter is easily clogged by impurities and affects the filtration permeability and efficiency.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] Optionally, the hydraulic scraper includes a flow chamber opened on the inner side of the top cover, one end of the inflow channel away from the connecting seat is connected to the flow chamber, the bottom of the flow chamber flows into the interior of the filter tank, the flow chamber is fixedly connected to the same bearing seat through a plurality of support rods distributed in a circular array, a transmission shaft is rotatably connected to the bearing seat, a plurality of leaf plates arranged in a circular array are fixedly connected to the outer circumference of the transmission shaft near the top thereof, the bottom end of the transmission shaft extends into the filter screen cylinder, and a plurality of scrapers arranged in a circular array are fixedly connected to the outer wall of the transmission shaft through a connecting bracket.

[0009] Optionally, the vertical cross-sections of the scrapers are all L-shaped structures, and the top cross-sections of the scrapers are all Z-shaped structures.

[0010] Optionally, an inclined scraping portion is provided on the outer edge of the scraper away from the connecting bracket, and a first weakened groove is provided on the inner wall of a corner of the scraper closest to the scraping portion.

[0011] Optionally, the transmission member includes a transmission rod located above the plurality of scrapers and fixedly connected to the outside of the transmission shaft, an annular groove is provided in the filter cylinder near the top thereof, one end of the transmission rod away from the transmission shaft is movably overlapped in the annular groove, an insertion channel is provided at the top edge of the filter cylinder, the top opening of the insertion channel is used to place one end of the transmission rod away from the transmission shaft, and the bottom end of the insertion channel is communicated with the interior of the annular groove.

[0012] Optionally, the annular groove has a circular wavy structure.

[0013] Optionally, a top opening of the insertion channel is provided with symmetrically distributed first inclined surfaces.

[0014] Optionally, a groove corresponding to the position of the insertion channel is formed on the inner side wall of the joint seat, and the groove is connected to the insertion channel. A blocking spring piece with an I-shaped structure in vertical cross section is fixed in the groove, and an inclined portion is provided at one end of the bottom of the blocking spring piece located in the insertion channel, and the inclined portion is used to prevent the end of the transmission rod away from the transmission shaft from escaping from the interior of the annular groove.

[0015] Optionally, the limiting buffer component includes a plurality of limiting plates fixed to the bottom end of the lap joint and arranged in a circular array, the bottom end of the limiting plate is provided with a symmetrically distributed second inclined surface, the top end of the limiting seat is provided with a limiting groove for inserting the limiting seat, the top opening of the limiting groove is provided with a symmetrically distributed third inclined surface, and the third inclined surfaces are matched with the second inclined surface on the corresponding side.

[0016] Optionally, a V-shaped portion arranged on the outer wall of the limiting plate is provided above each of the second inclined surfaces, a second weakening groove is provided at the corner of the V-shaped portion, and a reserved groove opened at the bottom end of the lap seat is provided between each two adjacent limiting plates.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, a hydraulic scraper is provided, and the extract of the blood-activating and stasis-removing soup is transported to the flow chamber through the liquid inlet pipe and the inflow channel by an external liquid pump device. Under the impact force when the extract enters, multiple leaf plates drive the transmission shaft to rotate counterclockwise on the bearing seat. At this time, multiple scrapers fixed to the connecting bracket will be driven to rotate. However, the scraping part provided on the scraper will fit the inner wall of the filter cylinder to scrape off the intercepted medicinal liquid impurities. In addition, under the setting of the first weakening groove, the structural strength of the scraper part at this place is weakened during the rotation of the scraper. Then, when the scraper part contacts the inner wall of the filter cylinder, the scraper part always maintains a fit state with the inner wall of the filter cylinder, thereby ensuring the scraping effect of the entire hydraulic scraper on the inner wall of the filter cylinder, and prompting the filter holes of the filter cylinder to ensure the best filtering and transparency state.

[0019] By setting a transmission part, on the basis of the operation of the above-mentioned hydraulic scraper, the transmission rod is made to rotate counterclockwise with the transmission shaft, and the end of the transmission rod away from the transmission shaft is overlapped in the annular groove. However, the annular groove is designed to be circular and wavy, so that the filter drum is driven to reciprocate up and down, which greatly improves the filtration efficiency of the filter drum. In addition, with the setting of the limit buffer part, the filter drum is not prone to rotation with the transmission shaft during the reciprocating up and down movement. On the other hand, under the action of the second weakening groove and multiple reserved grooves on the V-shaped portion, the force of the filter drum during the descent process can be buffered, effectively avoiding hard collision between the overlap seat and the limit seat.

[0020] Through the blocking piece arranged in the transmission member, especially when the filter cartridge needs to be removed for cleaning or replacement, due to the setting of the blocking piece to block the insertion channel, after manually loosening multiple locking devices and removing the top cover, the hydraulic scraper can be synchronously prompted to cooperate with the setting of the transmission member, and the filter cartridge can also be pulled out of the filter tank together, thereby greatly improving the efficiency of removing and cleaning the filter cartridge without the need for separate removal. On the contrary, when the filter cartridge is installed in the filter tank, it can be pre-fixed on the outside of the hydraulic scraper through the transmission member, thereby making the disassembly and assembly of the filter cartridge very convenient.

[0039] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides an extraction device for a Chinese herbal medicine extract for promoting blood circulation and unblocking meridians, the extraction device comprising a filter body 1, the filter body 1 is composed of a filter tank and a top cover 3, the filter tank and the top cover 3 are locked and fixed by multiple locking devices 4, a pressure gauge 31 is arranged on the top of the top cover 3, a limit seat 11 with a circular ring-shaped cross section is fixedly connected to a position near the top of the filter tank, the limit seat 11 is movably sleeved on the outside of a filter screen cylinder 12, a lap seat 13 with a circular ring-shaped cross section is fixedly connected to the outer periphery of the top of the filter screen cylinder 12, and the bottom end of the lap seat 13 is movably lapped on the limit seat The top of the filter body 11 is provided with an L-shaped liquid discharge pipe 22 at the bottom liquid discharge port of the filter body 1. An L-shaped liquid inlet pipe 21 fixedly connected to the outer wall of the filter tank through a connecting seat 2 is provided just above the flange portion at one end of the liquid discharge pipe 22. The top end of the liquid inlet pipe 21 is connected to an inflow channel 32 opened inside the top cover 3. A hydraulic scraper is installed on the top cover 3. The transmission member 6 and a limit buffer member 7 are also included. The transmission member 6 is installed in the filter screen cylinder 12 at a position close to the top thereof and is connected to the hydraulic scraper. The limit buffer member 7 is installed at the bottom end of the lap seat 13 and is connected to the top of the limit seat 11.

[0040] The locking device 4 is a component of the prior art filter and will not be described in detail. The top end of the filter tank and the bottom end of the top cover 3 are sealed with the prior art.

[0041] like Figures 2 to 9 As shown, in order to scrape the impurities on the inner wall of the inner filter screen cylinder 12 by the impact force of the Chinese medicine liquid transported to the flow chamber 5 through the liquid inlet pipe 21 and the inflow channel 32, the hydraulic scraper is provided to include a flow chamber 5 opened on the inner side of the top cover 3, and the end of the inflow channel 32 away from the connecting seat 2 is connected to the flow chamber 5, and the bottom of the flow chamber 5 flows into the interior of the filter tank. The same bearing seat 511 is fixedly connected in the flow chamber 5 through a plurality of support rods 51 distributed in a circular array, and a transmission shaft 52 is rotatably connected to the bearing seat 511. A plurality of blades 53 arranged in a circular array are fixedly connected on the outer circumference of the transmission shaft 52 near its top end, the bottom end of the transmission shaft 52 extends into the filter cylinder 12, and a plurality of scrapers 55 arranged in a circular array are fixedly connected on the outer wall of the transmission shaft 52 through a connecting bracket 54, the vertical cross-section of the scraper 55 is an L-shaped structure, the top cross-section of the scraper 55 is a Z-shaped structure, an inclined scraping portion is provided on the outer edge of the scraper 55 away from the connecting bracket 54, and a first weakening groove 56 is provided on the inner wall of a corner of the scraper 55 closest to the scraping portion.

[0042] The scraping part provided on the scraper 55 will fit the inner wall of the filter cylinder 12 to scrape the intercepted impurities of the liquid medicine. In addition, under the setting of the first weakening groove 56, the structural strength of the scraping part at this place is weakened during the rotation of the scraper 55, and then when the scraping part contacts the inner wall of the filter cylinder 12, the scraping part always keeps the contact state with the inner wall of the filter cylinder 12, so as to ensure the scraping effect of the entire hydraulic scraper on the inner wall of the filter cylinder 12; the setting of the first weakening groove 56 has another function, when the filter cylinder 12 is acted upon by the following transmission member 6 During the reciprocating up and down vibration process, the arc-shaped portion at the bottom end of the scraper 55 will collide with the inner bottom wall of the filter cylinder 12. The provision of the first weakening groove 56 can make the collision become a flexible collision, avoiding a hard collision that damages the inner surface of the filter cylinder 12 or reversely damages the scraping portion of the scraper 55. In addition, during the reciprocating up and down vibration of the filter cylinder 12, multiple scrapers 55 rotate, and the scrapers 55 all cooperate with the action of the first weakening groove 56, which can evenly apply the scraping force, reduce the dead angle of scraping impurities, and further improve the flow rate and efficiency through the filter.

[0043] like Figures 2 to 9 As shown, in order to realize the reciprocating up and down vibration of the filter drum 12 based on the operation of the above-mentioned hydraulic scraper, the transmission member 6 is provided to include a transmission rod 64 located above the plurality of scrapers 55 and fixedly connected to the outer side of the transmission shaft 52. An annular groove 61 is provided in the filter drum 12 near the top thereof, and one end of the transmission rod 64 away from the transmission shaft 52 is movably overlapped in the annular groove 61. An insertion channel 62 is provided at the top edge of the filter drum 12, and the top opening of the insertion channel 62 is used to place one end of the transmission rod 64 away from the transmission shaft 52 into the insertion channel. The bottom end of 62 is connected with the inside of the annular groove 61. The annular groove 61 has a circular wavy structure. A symmetrically distributed first inclined surface 63 is provided at the top opening of the insertion channel 62. A groove corresponding to the position of the insertion channel 62 is provided on the inner side wall of the lap seat 13. The groove is connected with the insertion channel 62. A blocking spring piece 65 with an I-shaped structure in vertical cross section is fixed in the groove. The bottom of the blocking spring piece 65 is located at one end of the insertion channel 62 and is provided with an inclined portion 66. The inclined portion 66 is used to prevent the end of the transmission rod 64 away from the transmission shaft 52 from escaping from the inside of the annular groove 61.

[0044] Among them, the setting of the inclined portion 66 on the blocking spring piece 65 is to squeeze the blocking spring piece 65 when the end of the transmission rod 64 away from the transmission shaft 52 enters, so that the inclined portion 66 of the blocking spring piece 65 is squeezed and deformed into the groove, and then after the end of the transmission rod 64 away from the transmission shaft 52 completely enters the annular groove 61, it can be actively reset to achieve the blocking limit of the end of the transmission rod 64 away from the transmission shaft 52; in addition, the width of the annular groove 61 matches the diameter of the end of the transmission rod 64 away from the transmission shaft 52, so as to prevent the filter cylinder 12 from moving up and down on the outside of the transmission rod 64 autonomously movement; the filter cartridge 12 mentioned in the beneficial effects can be removed from the top cover 3 at the same time, and combined with the functions of the hydraulic scraper and the transmission member 6, and can be pulled out from the filter tank together, and then the blocking spring piece 65 can be manually pressed to cause the inclined portion 66 of the blocking spring piece 65 to retract into the groove, thereby facilitating the end of the transmission rod 64 away from the transmission shaft 52 to be moved out from the insertion channel 62, and the removal of the filter cartridge 12 is quickly completed; the design of the first inclined surface 63 allows the end of the transmission rod 64 away from the transmission shaft 52 to be quickly and accurately inserted into the insertion channel 62, which plays a good guiding role.

[0045] like Figures 2 to 9 As shown, in order to buffer the force of the filter drum 12 descending during the reciprocating up and down vibration process, and to prevent the transmission shaft 52 from rotating during the reciprocating up and down movement of the filter drum 12, the limit buffer 7 is provided, including a plurality of limit plates 71 fixed to the bottom end of the lap seat 13 and arranged in a ring array, and a symmetrically distributed second inclined surface 73 is provided at the bottom end of the limit plate 71, and a limit groove 72 for inserting the limit seat 11 is provided at the top end of the limit seat 11, and a symmetrically distributed third inclined surface 74 is provided at the top opening of the limit groove 72, and the third inclined surfaces 74 are matched with the second inclined surfaces 73 on the corresponding side, and a V-shaped portion 75 is provided on the outer wall of the limit plate 71 above each second inclined surface 73, and a second weakening groove 76 is provided at the corner of the V-shaped portion 75, and a reserved groove 77 opened at the bottom end of the lap seat 13 is provided between each adjacent two limit plates 71.

[0046] Among them, the interior of the limit plate 71 is a hollow structure, and with the setting of the second weakened groove 76 on the V-shaped portion 75, the filter cylinder 12 can buffer the force of descent during the reciprocating up and down vibration process, avoiding a hard collision between the lap seat 13 and the limit seat 11, and can also effectively prevent the filter cylinder 12 from rotating; the setting of the third inclined surface 74 and the second inclined surface 73 is to ensure that the limit plate 71 can be quickly and accurately inserted into the limit groove 72 when inserted, and play a good guiding role.

[0047] The working principle of the technical solution provided by the present invention is as follows:

[0048] Step 1: The operator can use the liquid pump device to extract the semi-finished liquid medicine in the extracting tank of the blood circulation and blood stasis soup and transport it to the flow chamber 5 through the liquid inlet pipe 21 and the inflow channel 32. Under the impact of the extract entering, the multiple leaf plates 53 drive the transmission shaft 52 to rotate counterclockwise on the bearing seat 511. At this time, the multiple scrapers 55 fixed to the connecting bracket 54 will be driven to rotate. The scraping part set on the scraper 55 will fit the inner wall of the filter cylinder 12 to scrape the intercepted liquid impurities, so that the filter holes of the filter cylinder 12 are kept in the best filtering and transparent state;

[0049] Step 2: On the basis of the operation of the above-mentioned hydraulic scraper, the transmission rod 64 is rotated counterclockwise with the transmission shaft 52, and the end of the transmission rod 64 away from the transmission shaft 52 is overlapped in the annular groove 61. However, the annular groove 61 is designed to be circular and wavy, so that the filter drum 12 is driven to move back and forth up and down, which greatly improves the filtration efficiency of the filter drum 12. In addition, in conjunction with the setting of the limit buffer 7, the filter drum 12 is not prone to rotate with the transmission shaft 52 during the reciprocating up and down movement. On the other hand, under the action of the second weakening groove 76 and the multiple reserved grooves 77 arranged on the V-shaped portion 75, the force of the filter drum 12 during the descent process can be buffered, effectively avoiding a hard collision between the overlap seat 13 and the limit seat 11.

[0050] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
