Description

Technical Field

[0001] The invention belongs to the technical field of filtration and purification, and specifically refers to a multi-cycle filtration and purification device. Background Art

[0002] The purity of a liquid is mainly affected by the content of other substances in the liquid. For some insoluble impurities, they can be filtered out by physical means, but for some dissolved impurities (such as various liquids used in photovoltaic product processing), they need to be filtered and purified by unconventional methods such as chemical reactions and precipitation. The effect of physical filtration mainly depends on the pore size of the filter membrane, but chemical purification is different. Its effect is also closely related to the duration of the reaction.

[0003] If you want to extend the time of the purification reaction while other external conditions remain unchanged, the general approach is to increase the inner diameter of the cavity at the purification unit. By increasing the inner diameter cross-sectional area and reducing the flow rate, the time required for the liquid to pass through the purification unit can be extended. This method will generate vortices inside the purification unit, so the fluid does not pass through the unit completely evenly and linearly; that is to say, because the flow rate reduction is not uniform, the time taken for the fluid to pass through the purification unit will not be evenly extended.

[0004] In addition, when replacing the filter element of an ordinary purification and filtration device, it is generally necessary to close the valve first; if the maintenance interval is long, the subsequent filtration effect will be difficult to guarantee, and if the maintenance interval is short, it will affect the efficiency and continuity of the entire system. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a filtering and purification device by passing the filter element through a thin pipe multiple times; the present application adopts the method of alternating the operation and maintenance of two rows of filter elements, combined with the characteristics of the two rows of filter elements being arranged nearby, and can achieve the technical purpose of continuous and smooth filter element replacement and maintenance without stopping the machine during the process of replacing the filter element by "slowly reducing one cross-sectional area and slowly increasing the other cross-sectional area".

[0006] In order to realize the non-inductive replacement of two sets of filter elements without stopping the machine, there must be a stage where both filter elements participate in purification at the same time; however, from the perspective of spatial layout, since a single filter element completely leaves the pipe joint and the other filter element is completely in place, the sliding amplitude of the sliding bracket is very small (if the sliding amplitude is large, the available cross-sectional area will be too small when the two filter elements are in transition, and the flow rate and pressure will increase); At this time, if a maintenance hole is directly set on the side of the pipe joint part on the fixed support frame, a large amount of liquid leakage will inevitably occur during the transition process, but if no maintenance hole is set, it will be difficult to replace the filter element. In order to resolve this contradiction, the present invention starts from two embodiments, which can not only realize the rapid replacement of the filter element, but also avoid a large amount of liquid leakage during the replacement process.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a multi-cycle filtering and purification device, including a fixed support assembly and a transverse sliding mechanism, the fixed support assembly includes a spiral circulation pipe and a fixed support frame, the spiral circulation pipe is provided with a pipe joint part, the spiral circulation pipe is fixedly connected to the fixed support frame through the pipe joint part, both ends of the fixed support frame are provided with transverse guide grooves, the transverse sliding mechanism includes a maintenance sliding assembly, the maintenance sliding assembly includes a sliding bracket and a connecting pipe, both ends of the sliding bracket are symmetrically provided with sliding guide rods, the sliding guide rods are snap-fitted and slidably arranged in the transverse guide grooves, the connecting pipe is arranged on the sliding bracket, the filter element used for filtering and purification is located inside the connecting pipe, and the sliding bracket is driven by an external push rod.

[0008] In order to effectively prolong the purification and filtration time of the liquid, this scheme adopts the method of setting up multiple purification units on the spirally arranged pipe, which can make the actual duration and distance of the liquid flowing through the purification unit more stable, and solves the problem of inconsistent and difficult to unify flow rates in various parts in the traditional technical scheme of increasing the diameter to prolong the purification time.

[0009] Furthermore, the connecting pipes can slide along with the sliding of the sliding bracket. Through the reciprocating sliding of the sliding bracket, the two rows of connecting pipes alternately perform the two steps of filtering and purifying and replacing the filter element.

[0013] Through the bevel cooperation of the outer bevel portion and the inner bevel ring, the position of the connecting pipe can be automatically adjusted and pre-fixed, and the pre-positioning stability can be maintained to a certain extent by the pre-positioning spring; when the connecting pipe is not subjected to a large thrust, the connecting pipe can be maintained in a position coaxial with the pre-positioning circular hole, and when the connecting pipe is subjected to a large thrust, the connecting pipe will overcome the elastic force deviation of the pre-positioning spring, thereby facilitating replacement.

[0014] As a further preferred embodiment of the present invention, the locking assembly includes a locking pipe, a locking spring and an adsorption magnetic ring. The locking pipe is slidably arranged between the connecting pipe and the sliding sleeve. A sliding portion is provided on the locking pipe. The locking spring is arranged between the sliding portion and the sliding sleeve. The adsorption magnetic ring is fixed to the outer wall of the fixed support frame. The adsorption magnetic ring is sleeved on the spiral circulation pipe.

[0015] When the connecting pipe moves to the position where it is connected to the pipe joint, the extension and retraction of the locking pipe can be controlled by the adsorption magnetic ring, thereby automatically fixing the position of the connecting pipe for complete locking and unlocking.

[0016] Furthermore, the self-offsetting replacement assembly includes a replacement support assembly and a self-offsetting connection assembly, the replacement support assembly is arranged on a fixed support frame, and the self-offsetting connection assembly is arranged on the replacement support assembly.

[0017] Preferably, the replacement support assembly includes a connecting rod, a conveyor belt bracket and a conveyor roller, the connecting rod is fixedly connected to the fixed support frame, the conveyor belt bracket is fixedly connected to the connecting rod, the conveyor roller is rotatably arranged at both ends of the conveyor belt bracket, and the conveyor roller is driven by an external motor.

[0019] After the center fixture is connected to the elastic opening fixture, the elastic opening fixture supports the center fixture, so that a row of connecting pipes in maintenance status can be slightly laterally offset individually, which will not affect the use of the connecting pipes in working status and can avoid the problem of frequent engagement and separation of the sliding sleeve with the inner bevel ring when replacing the connecting pipes.

[0020] Furthermore, the fixed support assembly also includes a split fixing frame and an unfolding maintenance assembly, the split fixing frame is fixedly connected to both sides of the fixed support frame, the split fixing frame is provided with a maintenance hole, and the unfolding maintenance assembly array is arranged on the split fixing frame.

[0022] Although the second embodiment simplifies the structure of the filter device itself, it increases the dependence on external auxiliary equipment. Users can flexibly choose according to their own working conditions.

[0023] The beneficial effects achieved by the present invention using the above structure are as follows: (1) Through the structural design of the transverse sliding mechanism, the two-stage processing of pre-fixation and rigid locking of the connecting pipe is realized. The pre-fixation of the sliding bracket with a certain strength can automatically realize the connection and separation of the connecting pipe and the elastic opening clamp during the replacement process; on this premise, it can also ensure that the connecting pipe cannot be detached from the sliding bracket during the filtration process.

[0024] (2) In order to effectively extend the purification and filtration time of the liquid, this solution adopts the method of setting multiple purification filter elements on the spirally arranged pipeline, which can make the actual duration and distance of the liquid flowing through the purification unit more stable, thus solving the problem of inconsistent and difficult to unify flow rates in various parts in the traditional technical solution of increasing the diameter to extend the purification time.

[0025] (3) The position of the connecting pipe can be automatically adjusted and pre-fixed by the beveled cooperation between the outer beveled portion and the inner beveled circular ring, and a certain degree of stability of the pre-positioning can be maintained by the pre-positioning spring; when the connecting pipe is not subjected to a large thrust, the connecting pipe can be maintained in a position coaxial with the pre-positioning circular hole; when the connecting pipe is subjected to a large thrust, the connecting pipe will overcome the elastic force of the pre-positioning spring, thereby facilitating replacement.

[0026] (4) After the connecting pipe moves to the position where it is connected to the pipe joint, the extension and retraction of the locking pipe can be controlled by the adsorption magnetic ring, thereby automatically fixing the position of the connecting pipe for complete locking and unlocking.

[0027] (5) After the center clamp is connected to the elastic opening clamp, the elastic opening clamp can support the center clamp, so that a row of connecting pipes in the maintenance state can be slightly offset laterally. This will not affect the use of the connecting pipes in the working state, but also avoid the problem of frequent engagement and separation of the sliding sleeve with the inner bevel ring when replacing the connecting pipes.

[0028] (6) Although the second embodiment simplifies the structure of the filter device itself, it increases the dependence on external auxiliary equipment. Users can flexibly choose according to their own working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1 to Figure 16As shown, the present invention proposes a multi-cycle filtering and purification device, including a fixed support assembly 1 and a transverse sliding mechanism 2, the fixed support assembly 1 includes a spiral circulation pipe 4 and a fixed support frame 5, the spiral circulation pipe 4 is provided with a pipe joint part 8, the spiral circulation pipe 4 is fixedly connected to the fixed support frame 5 through the pipe joint part 8, and transverse guide grooves 9 are provided at both ends of the fixed support frame 5.

Sliding guide rods 26 are symmetrically provided at both ends of the sliding bracket 18, and the sliding guide rods 26 are snap-fitted and slidably arranged in the transverse guide grooves 9. The connecting pipe 19 is arranged on the sliding bracket 18, and the filter element used for filtering and purification is located inside the connecting pipe 19, and the sliding bracket 18 is driven by an external push rod.

[0035] In order to effectively prolong the purification and filtration time of the liquid, this scheme adopts the method of setting up multiple purification units on the spirally arranged pipe, which can make the actual duration and distance of the liquid flowing through the purification unit more stable, and solves the problem of inconsistent and difficult to unify flow rates in various parts in the traditional technical scheme of increasing the diameter to prolong the purification time.

[0036] The connecting pipes 19 can slide along with the sliding of the sliding bracket 18 . Through the reciprocating sliding of the sliding bracket 18 , the two rows of connecting pipes 19 alternately perform the two steps of filtering and purifying and replacing the filter element.

[0037] Embodiment 1: An array of pre-positioning circular holes 27 is provided on the sliding bracket 18 , and a central clamping platform 28 is provided in the middle of the connecting pipe 19 .

[0038] The transverse sliding mechanism 2 also includes a pre-fixing component 16 and a locking component 17 . The pre-fixing component 16 is slidably arranged on the connecting pipe 19 . The pre-fixing component 16 is symmetrically arranged. The locking component 17 is snap-fitted and slidably arranged in the pre-fixing component 16 .

[0039] The pre-fixing assembly 16 includes an inner bevel ring 20, a sliding sleeve 21 and a pre-positioning spring 22. The inner bevel ring 20 is fixed in the pre-positioning circular hole 27. The sliding sleeve 21 is slidably arranged on the connecting pipe 19. The sliding sleeve 21 is provided with an outer bevel portion 29 matching the inner bevel ring 20. The pre-positioning spring 22 is arranged between the sliding sleeve 21 and the center clamp 28.

[0040] Through the bevel cooperation between the outer bevel portion 29 and the inner bevel ring 20, the position of the connecting pipe 19 can be automatically adjusted and pre-fixed, and the pre-positioning stability can be maintained to a certain extent by the pre-positioning spring 22; when the connecting pipe 19 is not subjected to a large thrust, the connecting pipe 19 can be maintained in a coaxial position with the pre-positioning circular hole 27, and when the connecting pipe 19 is subjected to a larger thrust, the connecting pipe 19 will overcome the elastic force offset of the pre-positioning spring 22, thereby facilitating replacement.

The adsorption magnetic ring 25 is fixedly connected to the outer wall of the fixed support frame 5, and the adsorption magnetic ring 25 is sleeved on the spiral circulation pipe 4.

[0042] When the connecting pipe 19 moves to the position connected with the pipe joint 8, the extension and retraction of the locking pipe 23 can be controlled by the adsorption magnetic ring 25, so that the connecting pipe 19 is automatically completely locked and unlocked to fix the position.

The replacement support assembly 31 is arranged on the fixed support frame 5 , and the self-deflecting connection assembly 32 is arranged on the replacement support assembly 31 .

[0044] The replacement support assembly 31 includes a connecting rod 33, a conveyor belt bracket 34 and a conveyor roller 35. The connecting rod 33 is fixedly connected to the fixed support frame 5, the conveyor belt bracket 34 is fixedly connected to the connecting rod 33, and the conveyor roller 35 is rotatably arranged at both ends of the conveyor belt bracket 34. The conveyor roller 35 is driven by an external motor.

[0045] The self-deflecting connection assembly 32 includes a belt body 36 and an elastic opening clamp 37 . The belt body 36 and the conveying roller 35 are in rolling contact. The elastic opening clamp 37 is arranged in an array on the belt body 36 . The elastic opening clamp 37 is provided with an elastic opening portion 38 .

[0046] After the center clamp 28 is connected to the elastic opening clamp 37, the elastic opening clamp 37 supports the center clamp 28, so that a row of connecting pipes 19 in the maintenance state can be slightly laterally offset individually, which does not affect the use of the connecting pipes 19 in the working state and avoids the problem of frequent engagement and separation of the sliding sleeve 21 with the inner bevel ring 20 when replacing the connecting pipes 19.

[0047] Embodiment 2: The fixed support assembly 1 further comprises a split fixing frame 6 and an unfolding maintenance assembly 7. The split fixing frame 6 is fixedly connected to both sides of the fixed support frame 5. The split fixing frame 6 is provided with a maintenance hole 10.

The fixed part of the double-headed telescopic electric cylinder 13 is fixedly connected to the split fixed frame 6, and the telescopic part of the double-headed telescopic electric cylinder 13 is arranged on the maintenance plug 11.

[0049] Although the second embodiment simplifies the structure of the filter device itself, it increases the dependence on external auxiliary equipment. Users can flexibly choose according to their own working conditions.

[0050] During specific use, the liquid continues to flow along the spiral circulation pipe 4, and when passing through the connecting pipe 19, the liquid can be filtered and purified by the filter element inside the connecting pipe 19; however, since the filter element has a service life and its effect is also related to the length of use, in order to achieve a good filtering effect, it is necessary to replace the filter element in time, but this will lead to frequent shutdowns, affecting the efficiency and continuity of the entire system during operation.

[0051] Therefore, this solution focuses on how to achieve the technical purpose of replacing the filter element without stopping the machine; the specific process of replacing the filter element is as follows: Embodiment 1: The sliding bracket 18 slides in the fixed support frame 5 by pushing the sliding guide rod 26 through the external push rod. First, it will go through a transition stage. In this stage, both filter elements participate in filtration and purification. As the sliding bracket 18 slides, the interception area of ​​one filter element becomes larger and larger, and the interception area of ​​the other filter element becomes smaller and smaller. When the original connecting pipe 19 is completely separated from the pipe joint 8, the locking pipe 23 and the adsorption magnetic ring 25 move away from each other, and the locking pipe 23 is retracted into the sliding sleeve 21 under the elastic force of the locking spring 24, thereby releasing the rigid position fixation between the connecting pipe 19 and the sliding bracket 18; When the sliding bracket 18 is about to slide to the end, the central clamping platform 28 will first overcome the elastic force of the elastic opening portion 38 and enter the elastic opening clamping member 37. Then, when the sliding bracket 18 slides for the last short distance, since the central clamping platform 28 has been supported by the elastic opening portion 38 and cannot slide along with the sliding bracket 18, the outer bevel portion 29 of the sliding sleeve 21 will gradually separate from the inner bevel ring 20. Since the locking pipe 23 is located in the sliding sleeve 21, when the sliding sleeve 21 retracts, the locking pipe 23 and the sliding sleeve 21 will retract together, thereby completing the separation of the connecting pipe 19 and the sliding bracket 18. At this time, the external motor drives the conveying roller 35 to rotate, and the elastic opening clamp 37 can move longitudinally to drive the connecting pipe 19 away from the sliding bracket 18, and a new connecting pipe 19 is put in; In the next stage of reverse sliding of the sliding bracket 18, the new connecting pipe 19 is restrained in the elastic opening clamp 37 by the elastic force of the elastic opening portion 38, so it will first slide relative to the sliding bracket 18 until the inner bevel ring 20 and the outer bevel portion 29 are combined again; after the inner bevel ring 20 and the outer bevel portion 29 are combined, the sliding bracket 18 will slide with the connecting pipe 19 to overcome the elastic force of the elastic opening portion 38; when the connecting pipe 19 approaches the pipe joint portion 8 again, the locking pipe 23 will extend under the magnetic attraction of the adsorption magnetic ring 25 to complete the rigid locking of the connecting pipe 19.

[0052] Embodiment 2: The sliding bracket 18 slides in the fixed support frame 5 by pushing the sliding guide rod 26 through the external push rod. First, it will go through a transition stage. In this stage, both filter elements participate in filtration and purification. As the sliding bracket 18 slides, the interception area of ​​one filter element becomes larger and larger, and the interception area of ​​the other filter element becomes smaller and smaller. After the original connecting pipe 19 is completely separated from the pipe joint 8, the maintenance plug 11 is opened by extending the double-headed telescopic electric cylinder 13, and then the filter element in the connecting pipe 19 is pushed out by an external manipulator. After the new filter element is replaced, the maintenance plug 11 can be closed again by retracting the double-headed telescopic electric cylinder 13.

[0054] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
