Description

Technical Field

[0001] This invention relates to the field of sodium hyaluronate fermentation broth transportation, specifically to an automatic transportation device for sodium hyaluronate fermentation broth. Background Technology

[0002] Sodium hyaluronate fermentation broth typically refers to a sodium hyaluronate solution prepared through fermentation. It is widely used in the beauty industry for skin care products and fillers. The fermentation broth may have better biocompatibility and absorbability, contributing to skin moisturizing, repair, and anti-aging effects.

[0003] Existing technologies generally use fermentation to produce sodium hyaluronate. In the production process, sodium hyaluronate needs to undergo many steps such as fermentation, neutralization, and purification. Each step requires different machines for processing, and the fermentation liquid needs to be transported between every two machines through conveying equipment.

[0004] However, due to the characteristics of sodium hyaluronate fermentation broth, the following problems arise during processing and transportation: 1. Sodium hyaluronate fermentation broth oxidizes upon contact with air, producing deteriorated lumps. Furthermore, unclean conveying pipes or equipment can contaminate the fermentation broth, leading to these deteriorated lumps. The composition of these deteriorated lumps has changed, affecting the quality of the final product. General filtration devices need to ensure airtightness to prevent further oxidation of the sodium hyaluronate fermentation broth during filtration, making it difficult to clean the sieve plates during the filtration process. These sieve plates can become clogged after prolonged use, affecting filtration efficiency. 2. Sodium hyaluronate fermentation broth is also affected by temperature, forming clumps. These clumps have the same composition as the fermentation broth and will be filtered out along with the aforementioned deteriorated lumps, resulting in waste. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A base is included, characterized in that a heating conveying unit is fixedly connected to the left side of the base, and a filtering conveying unit is fixedly connected to the base and located to the right of the heating conveying unit.

One end of the semi-circular horizontal groove is connected to the upper end of the threaded inclined groove, and the other end of the semi-circular horizontal groove is connected to the lower end of the threaded inclined groove through the vertical straight groove.

[0009] As a preferred embodiment of the present invention, the stirring component includes a power tank fixedly connected to the top of the main shaft. A gear plate is provided inside the power tank. The upper side of the gear plate is fixedly connected to the top surface of the first tank body through a connecting rod. A bevel gear is rotatably connected to the inner side wall of the power tank. The bevel gear meshes with the gear plate. A sleeve is hinged to the outside of the power tank on the side of the bevel gear away from the connecting rod. A stirring blade is rotatably connected inside the sleeve.

[0010] As a preferred embodiment of the present invention, the stirring blade is uniformly provided with multiple sets of heating rods for heating the sodium hyaluronate fermentation broth, and a contact ball is fixedly connected to the end of the stirring blade away from the power tank; the side of the bevel gear away from the connecting rod is connected to the stirring blade through a transmission flexible shaft.

[0011] As a preferred embodiment of the present invention, the sieve hole control component includes a slide rail fixedly connected to the lower side of the movable filter plate, a baffle plate slidably connected inside the slide rail, a guide frame fixedly connected below the baffle plate, and an oblong groove on the inner side wall of the first tank at the corresponding height of the guide frame. The oblong groove is inclined, and the guide frame is L-shaped with its horizontal part inserted into the oblong groove. Since the oblong groove is inclined, when the movable filter plate moves downward, the guide frame, guided by the oblong groove, drives the baffle plate to block the sieve holes on the movable filter plate.

[0012] As a preferred embodiment of the present invention, the self-cleaning component includes an installation tank fixedly connected to the interior of a second tank. A fixing groove is fixedly connected to the left side of the inner wall of the second tank, located below the filter disc. The side of the fixing groove closest to the rotation direction of the filter disc is inclined, used to scoop up debris from the filter disc. A sliding groove is slidably connected within the fixing groove, with its left end passing through the second tank. A sealing plate is provided on the outer side of the left end of the second tank. The left ends of all sliding grooves are connected to the sealing plate. An airtight sealing strip is provided on the part of the sealing plate that is in contact with the second tank. A handle is fixedly connected to the left side of the sealing plate. Screen holes are provided at the bottom of both the fixing groove and the sliding groove, and the sliding groove contains adsorbent ceramic particles. Screen holes are also provided at the bottom of the installation tank.

[0013] As a preferred embodiment of the present invention, a gas outlet for introducing inert gas is fixedly installed on the top surface of the No. 1 tank; the No. 1 tank, the No. 2 tank, the valve pipe, and the discharge pipe and inlet pipe are all covered with heat insulation material to prevent the sodium hyaluronate fermentation liquid from clumping again after the temperature drops after heating is completed.

[0014] As a preferred technical solution of the present invention, a swing groove is provided on the inner side of the No. 1 tank at the corresponding height of the stirring component, and the contact ball is slidably connected in the swing groove, and the swing groove is deep enough so that the contact ball always slides in the swing groove.

[0015] The beneficial effects of the present invention are as follows: First, the heating and conveying unit of the present invention can stir and heat the sodium hyaluronate fermentation liquid through the stirring element, so that the clumps melt by heat. The stirring blades on the stirring element can rotate on their own axis while following the main shaft, and the stirring blades can swing under the guidance of the swing groove, so that the heating effect is more uniform. After heating, the clumps melt, effectively avoiding the problem of clumps and deteriorated clumps being filtered out together during filtration, which would cause waste.

[0016] Second, the heating and conveying unit of this invention lifts up any lumps that cannot be heated by a movable filter plate. The size of the sieve holes on the movable filter plate can be controlled by a sieve hole control component during the lifting process. As the movable filter plate moves upward, the sieve holes will enlarge under the action of the sieve hole control component, so that lumps of different sizes can be carried to different heights. The larger the lumps, the higher they will be carried, and the closer they will be to the heating and conveying unit, resulting in a faster melting speed and further increasing the heating effect.

[0017] Third, the filtration and conveying unit of this invention can filter the deteriorated blocks in the sodium hyaluronate fermentation liquid through the rotating filter element, and can clean the filter disc of the rotating filter element through the self-cleaning element, filter the deteriorated blocks on the filter disc, and collect the deteriorated blocks into the sliding groove. After the transportation is completed, the sliding groove can be pulled out by the handle to remove the deteriorated blocks inside, which is convenient and quick and does not affect the filtration.

[0029] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0030] See Figure 1 An automatic conveying device for sodium hyaluronate fermentation broth includes a base 1, a heating conveying unit 2 fixedly connected to the left side of the base 1, a filtering conveying unit 3 fixedly connected to the base 1 and located to the right of the heating conveying unit 2, an inlet pipe 20 fixedly connected to the heating conveying unit 2, and an outlet pipe 30 fixedly connected to the filtering conveying unit 3. The heating conveying unit 2 and the filtering conveying unit 3 are connected by a valve pipe 4.

[0031] This invention can stir and heat the sodium hyaluronate fermentation broth to melt the clumps; this invention can filter the deteriorated clumps in the sodium hyaluronate fermentation broth, and can also self-clean and collect the filtered deteriorated clumps.

[0032] Specifically, the feed pipe 20 and the discharge pipe 30 are first connected to the external output and input machines, respectively. Then, the sodium hyaluronate fermentation liquid is fed into the heating and conveying unit 2 through the feed pipe 20. The heating and conveying unit 2 stirs and heats the sodium hyaluronate fermentation liquid, causing the clumps to melt. After heating, the sodium hyaluronate fermentation liquid enters the filtration and conveying unit 3 through the valve pipe 4. The filtration and conveying unit 3 filters out the deteriorated clumps and collects them. After filtration, the sodium hyaluronate fermentation liquid is conveyed to other subsequent mechanisms through the discharge pipe 30.

[0033] See Figures 1-2 , Figures 4-5The heating and conveying unit 2 includes a first tank 21 fixedly connected to the base 1. A motor 211 is fixedly connected to the lower part of the first tank 21. The output shaft of the motor 211 passes through the lower side of the first tank 21, and a main shaft 22 is fixedly connected to the end of the output shaft. A guide groove 221 is provided on the main shaft 22. The guide groove 221 includes three parts: a first part is a threaded inclined groove, a second part is a semi-circular horizontal groove, and a third part is a vertical straight groove. One end of the semi-circular horizontal groove is connected to the upper end of the threaded inclined groove, and the other end of the semi-circular horizontal groove is connected to the lower end of the threaded inclined groove through the vertical straight groove. Multiple sliding grooves 212 are provided on the inner side wall of the first tank 21. All the chute 212 are slidably connected to a movable filter plate 23. The lower side of the movable filter plate 23 is connected to the No. 1 tank 21 through an energy storage spring 231. The movable filter plate 23 has multiple rows of sieve holes, and the arrangement direction of each row of sieve holes is pointing to the center of the movable filter plate 23. A sieve hole control component 24 is set on the lower side of the movable filter plate 23 and on the left side of the sieve holes. A guide pin 232 is fixedly connected to the side of the movable filter plate 23 near the main shaft 22. The guide pin 232 is inserted into the guide groove 221. A stirring component 25 is fixedly connected to the main shaft 22 and on the upper side of the movable filter plate 23. A gas outlet 11 for introducing inert gas is fixedly installed on the top surface of the No. 1 tank 21.

[0034] The heating conveying section 2 of this invention uses a movable filter plate 23 to lift up any clumps that have not been heated, resulting in a more comprehensive heating effect.

[0035] Specifically, firstly, inert gas is introduced through the gas outlet 11 to expel air from the heating conveying section 2 and the filtering conveying section 3, preventing oxidation of the sodium hyaluronate fermentation liquid during transportation. After the air is completely expelled, valve pipe 4 is closed. Then, the sodium hyaluronate fermentation liquid is introduced into the first tank 21 through the feed pipe 20, gradually filling the first tank 21 with the sodium hyaluronate fermentation liquid. Once the sodium hyaluronate fermentation liquid has submerged the stirring element 25, valve pipe 4 is opened, and motor 211 is started simultaneously. Motor 211 drives... When the main shaft 22 rotates, the movable filter plate 23 moves downward through the engagement of the threaded groove of the guide groove 221 and the guide pin 232. At the same time, the energy storage spring 231 is compressed. When the movable filter plate 23 moves downward to the lower side of the vertical straight groove, the guide pin 232 bounces upward along the vertical straight groove under the action of the energy storage spring 231, lifting the sediment on it. As the main shaft 22 continues to rotate, the guide pin 232 moves along the semi-circular horizontal groove to the upper end of the threaded groove. The above process is repeated as the main shaft 22 rotates.

[0036] See Figures 2-3 , Figure 6The stirring component 25 includes a power tank 251 fixedly connected to the top of the main shaft 22. A geared disc 252 is disposed inside the power tank 251. The upper side of the geared disc 252 is fixedly connected to the top surface of the first tank body 21 via a connecting rod 253. A bevel gear 254 is rotatably connected to the inner wall of the power tank 251, meshing with the geared disc 252. A sleeve 255 is hinged to the outer side of the power tank 251, on the side of the bevel gear 254 away from the connecting rod 253. A stirring blade 256 is rotatably connected inside the sleeve 255. The stirring blade 256 is equipped with... Multiple sets of heating rods for heating the sodium hyaluronate fermentation broth are evenly arranged. A contact ball 257 is fixedly connected to the end of the stirring blade 256 away from the power tank 251. The side of the bevel gear 254 away from the connecting rod 253 is connected to the stirring blade 256 through a transmission flexible shaft 258. A swing groove 214 is opened on the inner side of the first tank 21 at the corresponding height of the stirring component 25. The contact ball 257 is slidably connected in the swing groove 214, and the swing groove 214 is deep enough so that the contact ball 257 always slides in the swing groove 214.

[0037] The heating and conveying unit 2 of this invention can stir and heat the sodium hyaluronate fermentation liquid through the stirring member 25, so that the clumps melt by heating. The stirring blades 256 on the stirring member 25 can rotate on their own axis while following the main shaft 22. The stirring blades 256 can swing under the guidance of the swing groove 214, so that the heating effect is more uniform. After heating, the clumps melt, effectively avoiding the problem of clumps and deteriorated clumps being filtered out together during filtration, which would cause waste.

[0038] Specifically, when the motor 211 drives the main shaft 22 to rotate, the bevel gear 254 meshing with the gear disk 252 begins to rotate. The bevel gear 254 transmits the rotational torque to the stirring blade 256 through the transmission flexible shaft 258, causing the stirring blade 256 to start rotating within the sleeve 255. While the stirring blade 256 revolves around the main shaft 22, the contact ball 257, guided by the swing groove 214, causes the stirring blade 256 to start swinging back and forth around the hinge point between the sleeve 255 and the power tank 251.

[0039] It should be noted that the transmission flexible shaft 258 provided in this invention is existing technology, used to adapt to the angular deviation of the axis between the bevel gear 254 and the up-and-down swinging stirring blade 256 when transmitting torque.

[0040] See Figure 2 , Figure 4The sieve hole control component 24 includes a slide rail 241 fixedly connected to the lower side of the movable filter plate 23. A baffle plate 242 is slidably connected in the slide rail 241. A guide frame 243 is fixedly connected below the baffle plate 242. A waist-shaped groove 213 is opened on the inner side wall of the first tank 21 at the corresponding height of the guide frame 243. The waist-shaped groove 213 is inclined. The guide frame 243 is L-shaped, and its horizontal part is inserted into the waist-shaped groove 213. Since the waist-shaped groove 213 is inclined, when the movable filter plate 23 moves downward, the guide frame 243 drives the baffle plate 242 to block the sieve holes on the movable filter plate 23 under the guidance of the waist-shaped groove 213.

[0041] The present invention can control the size of the screen holes of the movable filter plate 23 by using the screen hole control component 24 to lift and control the size of the screen holes. When the movable filter plate 23 moves upward, the screen holes will become larger under the action of the screen hole control component 24, so that lumps of different sizes can be carried to different heights. The larger the lumps, the higher they will be carried, and the closer they will be to the heating and conveying part 2, the faster they will melt, and the further the heating effect will be increased.

[0042] Specifically, when the movable filter plate 23 moves downward, the guide frame 243, under the action of the waist-shaped groove 213, begins to drive the blocking plate 242 to move towards its corresponding screen hole, gradually blocking the screen hole and causing the flow rate of the screen hole to gradually decrease; when the movable filter plate 23 moves upward, the blocking plate 242 moves away from the screen hole, causing the flow rate of the screen hole to gradually increase. When moving upward, small clumps fall off first, and slightly larger clumps fall off later.

[0043] See Figures 7-9 The filtration and conveying unit 3 includes a second tank 31 fixedly connected to the base 1. An arc-shaped guide plate 311 is fixedly connected inside the second tank 31. A rotating filter element 32 is rotatably connected to the second tank 31 and located below the arc-shaped guide plate 311. A self-cleaning element 33 is provided on the second tank 31 and located to the left of the rotating filter element 32. The rotating filter element 32 includes a drive roller 321 fixedly connected to the bottom of the second tank 31. Multiple filter discs 322 are fixedly connected to the drive roller 321. The sieve holes of the filter discs 322 gradually decrease from top to bottom. An impeller 323 is fixedly connected to the drive roller 321 and located above the filter discs 322. The first tank 21, the second tank 31, the valve pipe 4, the discharge pipe 30, and the inlet pipe 20 are all covered with heat-insulating material to prevent the sodium hyaluronate fermentation liquid from clumping again after the temperature drops after heating.

[0044] The filter conveying unit 3 of the present invention can filter the deteriorated blocks in the sodium hyaluronate fermentation liquid by rotating the filter element 32, and can also prevent the deteriorated blocks from accumulating at the same place on the filter disc 322 and affecting the filtration effect by rotating.

[0045] Specifically, after heating the sodium hyaluronate fermentation liquid to melt the clumps inside, the heated sodium hyaluronate fermentation liquid is introduced into the No. 2 tank 31 through valve pipe 4. After entering the No. 2 tank 31, the sodium hyaluronate fermentation liquid is guided by the arc-shaped guide plate 311 and washes the impeller 323, so that the impeller 323 drives the filter disc 322 to rotate and filter through the drive roller 321.

[0046] See Figures 7-8 The self-cleaning component 33 includes an installation tank 331 fixedly connected inside the second tank 31. A fixing groove 332 is fixedly connected to the left side of the inner wall of the second tank 31 and below the filter disc 322. The side of the fixing groove 332 closest to the rotation direction of the filter disc 322 is inclined, used to scoop up debris on the filter disc 322. A sliding groove 333 is slidably connected inside the fixing groove 332. The left end of the sliding groove 333 passes through the second tank 31. A sealing plate 334 is provided on the outer side of the left end of the second tank 31. The left ends of all sliding grooves 333 are connected to the sealing plate 334. An airtight sealing strip is provided on the part of the sealing plate 334 that is in contact with the second tank 31. A handle 335 is fixedly connected to the left side of the sealing plate 334. Screen holes are opened at the bottom of both the fixing groove 332 and the sliding groove 333, and the sliding groove 333 contains adsorbent ceramic particles. Screen holes are also opened at the bottom of the installation tank 331.

[0047] The present invention can clean the filter disc 322 of the rotating filter element 32 by the self-cleaning component 33, filter the deteriorated blocks on the filter disc 322, and collect the deteriorated blocks into the sliding groove 333. After transportation, the sliding groove 333 can be pulled out by the handle 335 to remove the deteriorated blocks inside, which is convenient and quick and does not affect the filtration.

[0048] While the impeller 323 drives the filter disc 322 to rotate and filter via the drive roller 321, the inclined surface on the fixed groove 332 scoops up the debris on the filter disc 322 and accumulates it in the sliding groove 333. Since the filter disc 322 will also contain sodium hyaluronate fermentation liquid in addition to debris, the present invention provides sieve holes at the bottom of the sliding groove 333 and the fixed groove 332 to filter the scooped-up sodium hyaluronate fermentation liquid. After filtration, the sodium hyaluronate fermentation liquid is installed in the tank 33. The liquid flows through the sieve holes at the bottom of tank 1 to the bottom of tank 2 31, and is also filled with adsorbent ceramic particles in sliding groove 333 to adsorb the deteriorated blocks that enter sliding groove 333. After all the sodium hyaluronate fermentation liquid is filtered, it is discharged from the discharge pipe 30 to other subsequent mechanisms. After transportation is completed, the worker needs to pull out sliding groove 333 through handle 335, clean the adsorbent ceramic particles in it, and refill it with new adsorbent ceramic particles. After filling, sliding groove 333 is inserted back into its original position to wait for the next transportation.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
