Technical Field

[0001] The present invention relates to the technical field of filtration equipment, and specifically, to an impurity filtration equipment and method for essence water production. Background Art

[0002] In essence water production, impurity filtration is a key link to ensure product quality. Through filtration technology, mechanical impurities, colloidal particles and tiny suspended matters in water can be effectively removed, improving the clarity and transparency of essence water.

[0003] The patent with the application number CN202322976806.1 discloses an impurity filtration device for essence water production, including a box body, support feet and a filter box. The support feet are fixedly arranged on the bottom wall of the box body, and the support feet are arranged symmetrically in pairs. The filter box is arranged inside the box body, and also includes a filtration component and a feeding component. The filtration component is arranged inside the box body, and the feeding component is arranged on the top of the box body. Specifically, it is an impurity filtration device for essence water production that improves the filtration effect of essence water, ensures the stability of the filter box, reduces the occurrence of blockage, facilitates the cleaning of impurities, and improves the practicability of essence water filtration.

[0004] However, the existing essence water filtration equipment has many limitations: First, the equipment must be shut down when replacing the filter screen or cleaning the filter residue, and continuous production cannot be achieved, seriously restricting the production efficiency; Second, to meet the needs of different consumers and production, essence water usually needs to be divided into high-purity products suitable for high-end skin care products and low-purity products that meet specific efficacy requirements. However, the existing equipment usually only supports a single filtration accuracy and cannot achieve multi-stage configuration from coarse filtration to fine filtration in the same system. It is necessary to rely on subsequent packaging or connect multiple devices in series, significantly increasing the process complexity and cost; In addition, different purity liquids after filtration need to be collected through external pipelines or dispensing equipment, resulting in a bloated equipment structure, difficult maintenance and further increased costs.

[0005] In view of this, we propose an impurity filtration equipment and method for essence water production. Summary of the Invention

[0006] The purpose of the present invention is to provide an impurity filtration equipment and method for essence water production to solve the problems raised in the above background art.

When the centrifugal part rotates, the essence liquid flows into the filtering device from the bottom notch of the rotating pipe. The essence liquid filtered by centrifugation will flow into the discharge cavity from the inner wall ring groove and then flow into the inside of the discharge pipe through the discharge ring.

[0008] In the technical solution of the present invention, two symmetrically arranged slots and a plurality of regularly distributed limiting holes are opened on the inner wall of the tank body. The guide ring and the discharge ring are both welded and fixed on the inner side wall of the discharge cavity.

[0010] In the technical solution of the present invention, the transmission part includes a transmission shaft coaxially connected to the output shaft of the motor, a worm sleeved on the end of the transmission shaft, a sleeve rotatably connected to the top surface of the fixed cross plate, a worm gear welded on the top surface of the sleeve, and a plurality of convex strips integrally formed on the inner side wall of the sleeve. When the worm rotates, it drives the worm gear and the sleeve to rotate together, and then drives the rotating pipe to rotate accordingly.

[0011] In the technical solution of the present invention, a conical block is welded to the bottom wall of the rotating pipe.

A spring is welded and fixed to the inner side wall of the limiting block, and the other end of the spring is welded and fixed to the hole wall of the opening at the bottom end of the rotating pipe. The elastic force provided by the spring pushes the limiting block to move outwards.

[0012] In the technical solution of the present invention, the fixing part includes a fixing disk, two convex blocks integrally formed on the outer side wall of the fixing disk, a dial ring rotatably connected to the bottom surface of the fixing disk, and a plurality of inserting strips regularly distributed inside the fixing disk. A rotating ring groove is opened on the top surface of the fixing disk, a placing groove for the inserting strips to move is opened inside the fixing disk, a communication hole communicating with the bottom surface of the fixing disk is opened on the bottom surface of the placing groove, an outer convex ring sleeved with a collar in the lower filtering device is integrally formed on the bottom surface of the fixing disk, a plurality of arc grooves regularly distributed and penetrating up and down are opened on the top surface of the dial ring, and a convex rod passing through the communication hole and extending to the lower part of the arc groove at the end is integrally formed at the bottom end of the inserting strip.

[0013] In the technical solution of the present invention, the centrifugal part includes a centrifugal disk rotatably connected to the top surface of the fixing disk, a plurality of centrifugal arc plates welded and fixed to the top surface of the centrifugal disk, and a filter screen welded to the outside of the centrifugal disk. The cover plate is clamped and fixed to the top surface of the filter screen. The collar is welded and fixed to the cover plate. A plurality of jacks with the same number and corresponding positions as the limiting blocks are opened on the outer circumferential wall of the cover plate. The filter screens in different filtering devices can be adjusted according to the filtering requirements of the essence liquid.

[0014] In the technical solution of the present invention, the grading discharging device further includes a telescopic cylinder, a telescopic plate arranged at the end of the telescopic rod of the telescopic cylinder, and a connecting rod clamped and fixed between the bottom surface of the telescopic plate and the top of the discharging pipe. The telescopic cylinder is fixedly connected to the inside of the fixed cross plate by bolts. The telescopic plate is clamped and fixed to the telescopic rod of the telescopic cylinder, and the other end of the telescopic plate is sleeved on the outside of the rotating pipe.

[0015] In the technical solution of the present invention, a plurality of regularly distributed and internally and externally penetrating liquid inlet holes are opened on the right side wall of the discharging pipe, and an internally and externally penetrating discharging hole is opened on the left side wall of the discharging pipe. An inlet convex pipe clamped with the opening on the outer wall of the tank is integrally formed above the right side wall of the outer wrapping pipe, and a plurality of regularly distributed discharging convex pipes are integrally formed on the left side wall of the outer wrapping pipe. The filtered essence liquid will first flow into the inside of the discharging pipe from the inlet convex pipe and the liquid inlet holes of the discharging pipe, then flow into the corresponding discharging convex pipe from the discharging hole, and finally be discharged from the discharging convex pipe.

[0016] On the other hand, the present invention also provides an impurity filtering method for essence water production, using the above-mentioned impurity filtering equipment for essence water production, including the following steps: S1. First, control the telescopic cylinder to drive the telescopic plate to move, thereby driving the position of the rotating tube in the driving device, and move the bottom end of the rotating tube into the internal part of the filtering device located below; S2. At this time, under the elastic force of the spring, the end of the limiting block in the driving device extends into the jack of the outer collar, and the opening at the bottom end of the rotating tube is located below the cover plate; S3. Subsequently, start the motor in the driving device to drive the transmission shaft in the transmission part to rotate, and drive the worm at the end of the transmission shaft to rotate. After the worm contacts the worm gear, drive the worm gear and the sleeve to rotate together, and drive the rotating tube to rotate; S4. After the rotating tube rotates, drive the collar and the centrifugal part below it to rotate together. At this time, feed the produced essence liquid into the interior of the rotating tube through the feed pipe, and flow through the opening at the bottom end of the rotating tube into the interior of the centrifugal part; S5. The high-speed rotating centrifugal part throws out the essence liquid, and the filter screen filters the impurities in the essence liquid. The filtered essence liquid then flows into the interior of the discharge cavity through the inner wall annular groove on the outside of the filtering device, and drips downward through the guide ring onto the top surface of the discharge ring, and flows to the opening on the left side of the tank body on the inclined top surface of the discharge ring; S6. Then, the essence liquid flows into the interior of the discharge pipe through the feed convex pipe and the uppermost liquid inlet hole in the discharge pipe, and flows into the interior of the lowermost discharge convex pipe of the outer sleeve through the discharge hole of the discharge pipe. The operator then collects the flowing essence liquid; S7. After that, control the telescopic cylinder to drive the telescopic plate to move upward, and drive the discharge pipe to move upward inside the outer sleeve through the connecting rod, so that the middle liquid inlet hole is docked with the feed convex pipe; S8. During this process, the rotating tube in the driving device also moves upward with the telescopic plate, and dock the several limiting blocks on the outer side wall of the bottom end of the rotating tube with the collar in the filtering device above the lowermost filtering device. At this time, the continuously input essence liquid will be filtered through another filtering device; S9. Then, the operator can twist the dial ring in the lowermost filtering device, so that the position where the convex rod at the bottom end of the insert bar contacts the arc-shaped groove changes continuously, and then the end of the insert bar shrinks into the placement groove, thereby disassembling the lowermost filtering device and cleaning the filter residue on the filter screen; S10. After repeating the above operations, when the uppermost filtering device completes filtering and is removed, control the telescopic cylinder to move the opening at the bottom end of the rotating tube to the area of the liquid blocking pipe. After placing several new filtering devices in the tank body in sequence, control the telescopic cylinder to move downward intermittently, and then continue to filter the essence liquid.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The impurity filtration equipment and method for essence water production can drive the rotating pipe to move longitudinally through the telescopic cylinder, dynamically switch different levels of filtration devices, and during operation, the operator can detach the used filtration device below and replace it with a new component. This enables the overall device to continuously perform centrifugal filtration on the essence liquid and flexibly adjust the filter screen according to the characteristics of the essence liquid, supporting multi-level configurations from coarse filtration to fine filtration to meet diverse production requirements.

[0018] 2. The impurity filtration equipment and method for essence water production have a grading discharging device that adjusts the position of the discharge pipe in the outer casing pipe, allowing the essence liquid at different filtration levels to directly discharge from the corresponding discharge protruding pipe. This integrated design eliminates the need for additional material distribution equipment, reduces the complexity and cost of the equipment, and simultaneously meets the synchronous collection requirements for products with different purities.

Specific embodiments

[0020] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 14 As shown, this embodiment provides a technical solution: An impurity filtering device for essence water production, comprising a fixed tank 100, a driving device 200 arranged on the top surface of the fixed tank 100, a plurality of regularly distributed filtering devices 300, and a graded discharge device 400 arranged outside the fixed tank 100; In this embodiment, as Figures 2 - 4 shown, the fixed tank 100 is a cylindrical tank body 110. Inside the tank body 110, there is a cylindrical discharge cavity 111. Along the axial direction of the inner wall of the tank body 110, a plurality of inner wall annular grooves 112 communicating with the discharge cavity 111 are equally spaced. At the top of the inner wall annular groove 112, a material guiding ring 120 extends into the discharge cavity 111. Above the bottom of the discharge cavity 111, there is an inclined discharge ring 140.

[0022] Specifically, two symmetrically arranged slots 113 and a number of regularly distributed limiting holes 114 are formed in the inner wall of the tank body 110. The material guiding ring 120 and the discharging ring 140 are both welded and fixed to the inner groove wall of the discharging cavity 111. The top surface of the discharging ring 140 is inclined with the left side lower and the right side higher, so that the filtered essence can flow out from the opening at the left bottom end of the tank body 110. A number of regularly distributed reinforcing rods 130 are welded and fixed between the material guiding ring 120 and the outer groove wall of the discharging cavity 111. The outer side of the tank body 110 is fixedly connected with an outer jacket 150 through bolts. The top surface of the tank body 110 is fixedly connected with a fixed cross plate 160 through bolts. A liquid blocking pipe 170 is clamped on the bottom surface of the fixed cross plate 160.

[0023] Further, the tank body 110 is used to ensure the strength of the fixed tank 100. The essence filtered by the filtering device 300 will flow from the inner wall ring groove 112 to the discharging cavity 111, and then drip downward through the material guiding ring 120 onto the top surface of the discharging ring 140, and flow to the opening on the left side of the tank body 110 along the inclined top surface of the discharging ring 140. The slots 113 are used to limit the moving range of a number of filtering devices 300. The material guiding ring 120 is used to prevent the filtered essence from flowing into the inner wall ring groove 112 below it. The reinforcing rods 130 are used to ensure that the material guiding ring 120 can be fixed on the inner wall of the tank body 110. The outer jacket 150 is used to fix the whole device on an external support. The fixed cross plate 160 is used to provide a fixed platform for the driving device 200. The liquid blocking pipe 170 is used to prevent the essence from flowing out.

[0024] In this embodiment, as Figures 5 - 7 shown, the driving device 200 includes a motor 210, a rotating pipe 220 driven by the motor 210 to rotate, a transmission part 230 sleeved on the outer side of the rotating pipe 220, and a feeding pipe 270 arranged inside the rotating pipe 220.

[0025] Specifically, the motor 210 is fixedly connected to the top surface of the fixed cross plate 160 through bolts. A limiting ring groove 221 is formed at the top end of the rotating pipe 220. A number of regularly distributed inner grooves 222 are formed on the outer side wall of the rotating pipe 220. A number of regularly distributed openings for the essence to flow out are formed at the bottom end of the rotating pipe 220 and are through inside and outside.

[0026] Further, the transmission part 230 includes a transmission shaft 231 coaxially connected to the output shaft of the motor 210, a worm 232 sleeved on the end of the transmission shaft 231, a sleeve 233 rotatably connected to the top surface of the fixed cross plate 160, a worm gear 234 welded to the top surface of the sleeve 233, and a number of ridges 235 integrally formed on the inner side wall of the sleeve 233. When the worm 232 rotates, it drives the worm gear 234 and the sleeve 233 to rotate together, and then drives the rotating pipe 220 to rotate accordingly.

[0027] Further, a conical block 240 is welded to the bottom pipe wall of the rotating pipe 220. An opening at the bottom end of the outer side wall of the rotating pipe 220 is slidably connected with a limiting block 250. A spring 260 is welded and fixed to the inner side wall of the limiting block 250, and the other end of the spring 260 is welded and fixed to the hole wall of the opening at the bottom end of the rotating pipe 220. The elastic force provided by the spring 260 pushes the limiting block 250 to move outward.

[0028] Further, after the motor 210 is started, it drives the transmission shaft 231 in the transmission part 230 to rotate, and then drives the worm 232 at the end of the transmission shaft 231 to rotate. After the worm 232 abuts against the worm gear 234, it drives the worm gear 234 and the sleeve 233 to rotate together, and the sleeve 233 drives the rotating pipe 220 to rotate through the inner rib 235. The conical block 240 is used to evenly distribute the falling essence.

[0029] In this embodiment, as Figures 9 - 12 shown, the filtering device 300 includes a fixing part 310, a centrifugal part 320, a cover plate 330 and a collar 340 arranged from bottom to top. The positions of several filtering devices 300 fixed inside the tank body 110 correspond one by one to the positions of several inner wall grooves 112.

[0030] Specifically, the fixing part 310 includes a fixing disk 311, two convex blocks 312 integrally formed on the outer side wall of the fixing disk 311, a dial ring 313 rotatably connected to the bottom surface of the fixing disk 311, and several inserting strips 314 regularly distributed inside the fixing disk 311. A rotating ring groove 3110 is formed on the top surface of the fixing disk 311, a placing groove 3111 for the inserting strip 314 to move is formed inside the fixing disk 311, a communication hole 3112 communicating with the bottom surface of the fixing disk 311 is formed on the bottom surface of the placing groove 3111, an outer convex ring sleeved with the collar 340 in the lower filtering device 300 is integrally formed on the bottom surface of the fixing disk 311, several arc-shaped grooves 3130 regularly distributed and vertically penetrating are formed on the top surface of the dial ring 313, and a convex rod passing through the communication hole 3112 and extending to the lower part of the arc-shaped groove 3130 is integrally formed at the bottom end of the inserting strip 314.

[0031] Further, the centrifugal part 320 includes a centrifugal disk 321 rotatably connected to the top surface of the fixing disk 311, several centrifugal arc plates 322 welded and fixed to the top surface of the centrifugal disk 321, and a filter screen 323 welded to the outside of the centrifugal disk 321. The cover plate 330 is snap-fitted and fixed to the top surface of the filter screen 323. The collar 340 is welded and fixed to the cover plate 330. Several jacks 341 with the same number and corresponding positions as the limiting blocks 250 are formed on the outer circumferential wall of the cover plate 330. The filter screens 323 in different filtering devices 300 can be adjusted according to the filtering requirements of the essence.

[0032] Further, under the elastic force of the spring 260, the end of the limit block 250 extends into the jack 341 of the outer collar 340. When the rotating tube 220 rotates, it drives the collar 340 to rotate. After the collar 340 rotates, it drives the cover plate 330 and the centrifugal part 320 clamped under the cover plate 330 to rotate together. At this time, the essence liquid will be thrown out towards the filter screen 323 under the action of centrifugal force, and the essence liquid is filtered through the filter screen 323. The centrifugal arc plate 322 is used to allow the essence liquid to be thrown out from its outer end.

[0033] Further, the convex block 312 on the fixed disk 311 cooperates with the slot 113 to limit the moving range of the filtering device 300. The operator can twist the dial ring 313 in the filtering device 300, so that the position where the convex rod at the bottom end of the insert bar 314 contacts the arc-shaped groove 3130 changes continuously. Then, the insert bar 314 moves inside the placement groove 3111, and the end of the insert bar 314 can stretch inside the limit hole 114, so as to quickly install and disassemble the filtering device 300.

[0034] In this embodiment, as Figures 13 - 14 shown, the grading discharging device 400 includes a discharge pipe 440 for draining the filtrate of a plurality of filtering devices 300 and an outer pipe 450 sleeved outside the discharge pipe 440 for draining the filtrate. Specifically, the grading discharging device 400 further includes a telescopic cylinder 410, a telescopic plate 420 arranged at the end of the telescopic rod of the telescopic cylinder 410, and a connecting rod 430 clamped and fixed between the bottom surface of the telescopic plate 420 and the top of the discharge pipe 440. The telescopic cylinder 410 is fixedly connected to the inside of the fixed horizontal plate 160 by bolts. The telescopic plate 420 is clamped and fixed to the telescopic rod of the telescopic cylinder 410, and the other end of the telescopic plate 420 is sleeved outside the rotating tube 220.

[0035] Further, a plurality of regularly distributed liquid inlet holes 441 that penetrate inside and outside are formed on the right side wall of the discharge pipe 440, and a discharge hole 442 that penetrates inside and outside is formed on the left side wall of the discharge pipe 440. An inlet convex pipe 451 that is integrally formed and is clamped with the opening on the outer wall of the tank body 110 is formed above the right side wall of the outer pipe 450, and a plurality of regularly distributed discharge convex pipes 452 are integrally formed on the left side wall of the outer pipe 450. The filtered essence liquid will first flow into the inside of the discharge pipe 440 through the inlet convex pipe 451 and the liquid inlet holes 441 of the discharge pipe 440, then flow into the corresponding discharge convex pipe 452 from the discharge hole 442, and finally be discharged from the discharge convex pipe 452.

[0036] Further, while the discharge pipe 440 moves inside the outer pipe 450, the position of the rotating pipe 220 also changes. The rotating pipe 220 transmits rotational motion. After the centrifugal part 320 rotates, the essence liquid flows into the filtering device 300 from the bottom notch of the rotating pipe 220. The essence liquid that has undergone centrifugal filtration will flow into the discharge cavity 111 from the inner wall annular groove 112 and then flow into the inside of the discharge pipe 440 through the discharge ring 140.

[0037] Further, after the telescopic cylinder 410 is activated, it can change the position of the telescopic plate 420. Through the connecting rod 430, when the telescopic plate 420 moves, it can change the positions of the rotating pipe 220 and the discharge pipe 440. The movement of the discharge pipe 440 inside the outer pipe 450 allows the feeding convex pipe 451 to be docked with different liquid inlet holes 441 and the discharge hole 442 to be docked with different discharge convex pipes 452.

[0038] The present invention also provides an impurity filtration method for essence water production, using the above-mentioned impurity filtration equipment for essence water production. When in use, it includes the following steps: S1. First, control the telescopic cylinder 410 to drive the telescopic plate 420 to move, thereby driving the position of the rotating pipe 220 in the driving device 200, and move the bottom end of the rotating pipe 220 into the filtering device 300 located below. S2. At this time, under the elastic force of the spring 260, the end of the limit block 250 in the driving device 200 extends into the jack 341 of the outer collar 340, and the opening at the bottom end of the rotating pipe 220 is located below the cover plate 330. S3. Subsequently, start the motor 210 in the driving device 200 to drive the transmission shaft 231 in the transmission part 230 to rotate, and drive the worm 232 at the end of the transmission shaft 231 to rotate. After the worm 232 contacts the worm gear 234, drive the worm gear 234 and the sleeve 233 to rotate together, and drive the rotating pipe 220 to rotate. S4. After the rotating pipe 220 rotates, drive the outer collar 340 and the centrifugal part 320 below it to rotate as a whole. At this time, the produced essence liquid is fed into the inside of the rotating pipe 220 through the feed pipe 270 and flows to the inside of the centrifugal part 320 through the opening at the bottom end of the rotating pipe 220. S5. The high-speed rotating centrifugal part 320 throws out the essence liquid, and the filter screen 323 filters the impurities in the essence liquid. The filtered essence liquid then flows into the inside of the discharge cavity 111 from the inner wall annular groove 112 on the outside of the filtering device 300, and drips downward through the guide ring 120 onto the top surface of the discharge ring 140, and flows to the opening on the left side of the tank body 110 on the inclined top surface of the discharge ring 140. S6. Next, the essence flows into the interior of the discharge pipe 440 through the liquid inlet hole 441 at the uppermost position in the feed convex pipe 451 and the discharge pipe 440, and then flows into the interior of the discharge convex pipe 452 at the lowermost position of the outer wrapper pipe 450 through the discharge hole 442 of the discharge pipe 440. Then, the operator immediately collects the flowing essence. S7. After that, control the telescopic cylinder 410 to drive the telescopic plate 420 to move upward, and drive the discharge pipe 440 to move upward inside the outer wrapper pipe 450 through the connecting rod 430, so that the liquid inlet hole 441 in the middle is docked with the feed convex pipe 451. S8.
