Description

Technical Field

[0001] The present invention belongs to the technical field of filtration and purification, and specifically refers to a filtration and purification device with multiple cycles. Background Art

[0002] The purity of a liquid is mainly affected by the content of other substances in the liquid. For some insoluble impurities, physical filtration can be used, but for some dissolved impurities (such as various liquids used in photovoltaic product processing), unconventional methods such as chemical reactions and precipitation are required for filtration and purification.

[0003] The effect of physical filtration mainly depends on the pore size of the filter membrane, while chemical purification is different, and its effect is also closely related to the duration of the reaction.

[0004] Under the condition that other external conditions remain unchanged, to extend the time of the purification reaction, the general method is to increase the inner diameter of the cavity at the purification unit, and by increasing the inner diameter cross-sectional area and reducing the flow rate, extend the time required for the liquid to pass through the purification unit. Since eddy currents will be generated inside the purification unit in this way, the fluid does not pass through the unit completely evenly and linearly; that is to say, because the reduction amplitude of the flow rate is not uniform, the time used for the fluid to pass through the purification unit will not be evenly extended.

[0005] In addition, when replacing the filter element of an ordinary purification and filtration device, the valve generally needs to be closed first; if the maintenance interval is long, it is difficult to ensure the later filtration effect, and if the maintenance interval is short, it will affect the efficiency and continuity of the entire system operation. Summary of the Invention

[0006] In view of the above situation, to overcome the defects of the prior art, the present invention proposes a filtration and purification device that passes through the filter element multiple times in a thin pipe; through the way of alternately working and maintaining two columns of filter elements, combined with the characteristics of the two columns of filter elements being arranged nearby, the technical purpose of continuously and smoothly replacing and maintaining the filter element without shutting down can be achieved by the method of "one cross-sectional area slowly decreasing and the other cross-sectional area slowly increasing" during the process of replacing the filter element.

[0007] To achieve the seamless replacement of two groups of filter elements without shutting down, there must be a stage where two filter elements participate in purification at the same time; however, considering the spatial layout, since the sliding amplitude of the sliding bracket is very small when a single filter element completely leaves the pipe joint and another filter element is completely in place (if the sliding amplitude is large, it will cause a situation where the available cross-sectional area is too small, and the flow rate and pressure increase during the transition of the two filter elements);

[0008] At this time, if a maintenance hole is directly provided 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. However, if the maintenance hole is not provided, it will be very difficult to replace the filter element. To solve this contradiction, the present invention starts from two embodiments, which can not only achieve the rapid replacement of the filter element, but also avoid a large amount of liquid leakage during the replacement process.

[0009] The technical solution adopted by the present invention is as follows: The present invention provides a multi-cycle filtration and purification device, including a fixed support component and a transverse sliding mechanism. The fixed support component includes a spiral circulation pipe and a fixed support frame. A pipe joint part is provided on the spiral circulation pipe, and the spiral circulation pipe is fixedly connected to the fixed support frame through the pipe joint part. Transverse guide grooves are provided at both ends of the fixed support frame. The transverse sliding mechanism includes a maintenance sliding component. The maintenance sliding component includes a sliding bracket and a connecting pipe. Sliding guide rods are symmetrically provided at both ends of the sliding bracket, and the sliding guide rods are engaged and slidably arranged in the transverse guide grooves. The connecting pipe is arranged on the sliding bracket, and a filter element for filtration and purification is located inside the connecting pipe. The sliding bracket is driven by an external push rod.

[0010] In order to effectively extend the purification and filtration time of the liquid, this solution adopts the method of arranging multiple purification units on the spirally arranged pipe, which can make the continuous time and distance of the liquid actually flowing through the purification unit relatively stable, and solves the problems of non-uniform and difficult-to-unify flow velocities in each part in the traditional technical solution of increasing the diameter to extend the purification time.

[0011] Furthermore, the connecting pipe 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 two steps of filtration and purification and filter element replacement.

[0012] Preferably, pre-positioning round holes are arranged in an array on the sliding bracket, and a central clamping platform is arranged at the middle position of the connecting pipe.

[0013] Furthermore, the transverse sliding mechanism further includes a pre-fixing component and a locking component. The pre-fixing component is slidably arranged on the connecting pipe, the pre-fixing component is symmetrically arranged, and the locking component is engaged and slidably arranged in the pre-fixing component.

[0014] Preferably, the pre-fixing component includes an inner beveled ring, a sliding sleeve and a pre-positioning spring. The inner beveled ring is fixedly connected to the pre-positioning round hole, the sliding sleeve is slidably arranged on the connecting pipe, an outer beveled part matching the inner beveled ring is arranged on the sliding sleeve, and the pre-positioning spring is arranged between the sliding sleeve and the central clamping platform.

[0015] Through the bevel angle cooperation between the outer bevel angle part and the inner bevel angle ring, the position of the connecting pipe can be automatically adjusted and pre-fixed, and this pre-positioning can be maintained to a certain extent by the pre-positioning spring; when the thrust on the connecting pipe is not large, the connecting pipe can be maintained at a position coaxial with the pre-positioning round hole, and when the connecting pipe is subjected to a large thrust, the connecting pipe will overcome the elastic force of the pre-positioning spring and shift, thus facilitating replacement.

[0016] As a further preference of the present invention, the locking assembly includes a locking pipe, a locking spring and an adsorption magnetic ring. The locking pipe is clamped and slidably arranged between the connecting pipe and the sliding sleeve. A sliding part is arranged on the locking pipe. The locking spring is arranged between the sliding part and the sliding sleeve. The adsorption magnetic ring is fixedly connected to the outer wall of the fixed support frame, and the adsorption magnetic ring is sleeved on the spiral circulating pipe.

[0017] After the connecting pipe moves to the position connected to the pipe joint, the adsorption magnetic ring can control the extension and retraction of the locking pipe, so as to automatically fix the position of the complete locking and unlocking of the connecting pipe.

[0018] Furthermore, the self-offset replacement assembly includes a replacement support assembly and a self-offset connection assembly. The replacement support assembly is arranged on the fixed support frame, and the self-offset connection assembly is arranged on the replacement support assembly.

[0019] Preferably, the replacement support assembly includes a connecting rod, a conveyor belt support and a conveyor roller. The connecting rod is fixedly connected to the fixed support frame, the conveyor belt support is fixedly connected to the connecting rod, the conveyor roller is rotatably arranged at both ends of the conveyor belt support, and the conveyor roller is driven by an external motor.

[0020] The self-offset connection assembly includes a belt body and an elastic opening clip. The belt body is in rolling contact with the conveyor roller. The elastic opening clips are arranged in an array on the belt body, and an elastic opening part is arranged on the elastic opening clip.

[0021] After the central card table is connected to the elastic opening clip, by the top support of the elastic opening clip on the central card table, a small lateral offset can occur independently for a row of connecting pipes in the maintenance state, which neither affects the use of the connecting pipes in the working state nor avoids the problem that the sliding sleeve frequently combines and separates with the inner bevel angle ring when replacing the connecting pipes.

[0022] Furthermore, the fixed support assembly further includes a split fixed frame and a deployment maintenance assembly. The split fixed frame is fixedly connected to both sides of the fixed support frame. Maintenance holes are arranged on the split fixed frame, and the deployment maintenance assemblies are arranged in an array on the split fixed frame.

[0023] Preferably, the unfolding and maintenance component includes a maintenance plug, a guide sleeve rod, and a double-headed telescopic electric cylinder. The maintenance plug is provided with a plug guide rod. The maintenance plug is slidably engaged with the split-type fixed frame through the plug guide rod. When the maintenance plug retracts, it can completely close the maintenance hole. The guide sleeve rod is fixedly connected to the split-type fixed frame, and the plug guide rod is slidably engaged in the guide sleeve rod. The fixed part of the double-headed telescopic electric cylinder is fixedly connected to the split-type fixed frame, and the telescopic part of the double-headed telescopic electric cylinder is arranged on the maintenance plug.

[0024] Although the structure of the filtering device itself is simplified in the second embodiment, the dependence on external auxiliary equipment is increased. Users can flexibly select according to their own working conditions.

[0025] The beneficial effects achieved by the present invention with the above structure are as follows:

[0026] (1) Through the structural design of the transverse sliding mechanism, the processing of two stages of pre-fixing and rigid locking of the connecting pipe is realized. It can not only automatically realize the combination and separation of the connecting pipe and the elastic opening fastener during the replacement process through the pre-fixing with a certain strength of the sliding bracket, but also ensure that the connecting pipe cannot be separated from the sliding bracket during the filtering process on this premise.

[0027] (2) In order to effectively extend the purification and filtration time of the liquid, this solution adopts the method of arranging multiple purification filter elements on the spirally arranged pipe, which can make the duration and distance of the liquid actually flowing through the purification unit relatively stable, and solves the problems of inconsistent and difficult-to-unify flow rates in each part in the traditional technical solution of increasing the diameter to extend the purification time.

[0028] (3) Through the bevel angle cooperation between the outer bevel angle part and the inner bevel angle ring, the position of the connecting pipe can be automatically adjusted and pre-fixed, and this pre-positioning can be maintained to a certain extent by the pre-positioning spring. When the thrust received by the connecting pipe is not large, the connecting pipe can maintain a position coaxial with the pre-positioning round hole. When the connecting pipe receives a large thrust, the connecting pipe will overcome the elastic force of the pre-positioning spring and shift, thus facilitating replacement.

[0029] (4) After the connecting pipe moves to the position connected to the pipe joint, the adsorption magnetic ring can control the extension and retraction of the locking pipe, so as to automatically fix the position of the complete locking and unlocking of the connecting pipe.

[0030] (5) After the central card table is connected to the elastic opening fastener, through the top support of the elastic opening fastener on the central card table, a small lateral offset can occur independently for a row of connecting pipes in the maintenance state, which neither affects the use of the connecting pipes in the working state nor avoids the problem of frequent combination and separation of the sliding sleeve and the inner bevel angle ring when replacing the connecting pipe.

[0031] (6) Although Embodiment 2 simplifies the structure of the filtration device itself, it increases the dependence on external auxiliary equipment, and users can flexibly select according to their own working conditions. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0051] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0052] Such as Figures 1 to 16As shown in the figure, the present invention provides a filtration and purification device with multiple cycles, including a fixed support assembly 1 and a transverse sliding mechanism 2. The fixed support assembly 1 includes a spiral circulation pipeline 4 and a fixed support frame 5. A pipeline joint 8 is provided on the spiral circulation pipeline 4, and the spiral circulation pipeline 4 is fixedly connected to the fixed support frame 5 through the pipeline joint 8. Transverse guide grooves 9 are provided at both ends of the fixed support frame 5. The transverse sliding mechanism 2 includes a maintenance sliding assembly 15. The maintenance sliding assembly 15 includes a sliding bracket 18 and a connecting pipeline 19. Sliding guide rods 26 are symmetrically provided at both ends of the sliding bracket 18, and the sliding guide rods 26 are engaged and slidably arranged in the transverse guide grooves 9. The connecting pipeline 19 is arranged on the sliding bracket 18, and a filter element for filtration and purification is located inside the connecting pipeline 19. The sliding bracket 18 is driven by an external push rod.

[0053] In order to effectively extend the purification and filtration time of the liquid, this solution adopts the method of arranging multiple purification units on the spirally arranged pipeline, which can make the duration and distance of the liquid actually flowing through the purification unit relatively stable, and solves the problems of non-uniform and difficult-to-unify flow rates in each part in the traditional technical solution of increasing the diameter to extend the purification time.

[0054] The connecting pipeline 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 pipelines 19 alternately perform two steps of filtration and purification and filter element replacement.

[0055] Embodiment 1: Pre-positioning round holes 27 are arranged in an array on the sliding bracket 18, and a central clamping platform 28 is arranged at the middle position of the connecting pipeline 19.

[0056] The transverse sliding mechanism 2 further includes a pre-fixing component 16 and a locking component 17. The pre-fixing component 16 is slidably arranged on the connecting pipeline 19, the pre-fixing component 16 is symmetrically arranged, and the locking component 17 is engaged and slidably arranged in the pre-fixing component 16.

[0057] The pre-fixing component 16 includes an inner beveled ring 20, a sliding sleeve 21 and a pre-positioning spring 22. The inner beveled ring 20 is fixedly connected to the pre-positioning round hole 27. The sliding sleeve 21 is slidably arranged on the connecting pipeline 19. An outer beveled portion 29 matching the inner beveled ring 20 is arranged on the sliding sleeve 21. The pre-positioning spring 22 is arranged between the sliding sleeve 21 and the central clamping platform 28.

[0058] Through the bevel cooperation of the outer beveled portion 29 and the inner beveled ring 20, the position of the connecting pipeline 19 can be automatically adjusted and pre-fixed, and the stability of this pre-positioning can be maintained to a certain extent through the pre-positioning spring 22; when the thrust received by the connecting pipeline 19 is not large, the connecting pipeline 19 can maintain a coaxial position with the pre-positioning round hole 27, and when the connecting pipeline 19 receives a large thrust, the connecting pipeline 19 will overcome the elastic force of the pre-positioning spring 22 and shift, so as to facilitate replacement.

[0059] The locking assembly 17 includes a locking pipe 23, a locking spring 24, and an adsorption magnetic ring 25.

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.

[0060] After the connecting pipe 19 moves to the position connected to the pipe joint 8, the extension and retraction of the locking pipe 23 can be controlled by the adsorption magnetic ring 25, so as to automatically fix the position of the complete locking and unlocking of the connecting pipe 19.

[0062] The replacement support assembly 31 includes a connecting rod 33, a conveyor belt support 34, and a conveyor roller 35. The connecting rod 33 is fixedly connected to the fixed support frame 5. The conveyor belt support 34 is fixedly connected to the connecting rod 33. The conveyor roller 35 is rotatably disposed at both ends of the conveyor belt support 34, and the conveyor roller 35 is driven by an external motor.

[0063] The self-offset connection assembly 32 includes a belt body 36 and an elastic opening clip 37. The belt body 36 is in rolling contact with the conveyor roller 35. The elastic opening clips 37 are arranged in an array on the belt body 36, and an elastic opening portion 38 is provided on the elastic opening clip 37.

[0064] After the central clamping table 28 is connected to the elastic opening clip 37, by the propping of the elastic opening clip 37 on the central clamping table 28, a small lateral offset can occur independently for a row of connecting pipes 19 in the maintenance state, which neither affects the use of the connecting pipes 19 in the working state nor avoids the problem that the sliding sleeve 21 frequently combines and separates with the inner beveled ring 20 when replacing the connecting pipes 19.

[0065] Embodiment 2: The fixed support assembly 1 further includes a split fixed frame 6 and an unfolding maintenance assembly 7. The split fixed frame 6 is fixedly connected to both sides of the fixed support frame 5. A maintenance hole 10 is provided on the split fixed frame 6.

The plug guide rod 14 is slidably engaged with the guide sleeve 12. 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.

[0067] 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.

[0068] 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.

[0069] 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:

[0070] 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.

[0071] 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;

[0072] 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.

[0073] At this time, by rotating the conveying roller 35 with an external motor, the connecting pipe 19 can be taken away from the sliding bracket 18 through the longitudinal movement of the elastic opening clip 37, and a new connecting pipe 19 can be put in.

[0074] In the stage when the next sliding bracket 18 slides in the reverse direction, since the new connecting pipe 19 is bound in the elastic opening clip 37 by the elastic force of the elastic opening part 38, it will first slide relative to the sliding bracket 18 until the inner beveled ring 20 and the outer beveled part 29 are combined again; after the inner beveled ring 20 and the outer beveled part 29 are combined, the sliding bracket 18 will drive the connecting pipe 19 to slide together against the elastic force of the elastic opening part 38; when the connecting pipe 19 approaches the pipe joint 8 again, the locking pipe 23 will extend under the magnetic suction force of the adsorption magnetic ring 25 to complete the rigid locking of the connecting pipe 19.

[0075] Embodiment 2: The sliding bracket 18 slides in the fixed support frame 5 by pushing the sliding guide rod 26 with an external push rod. First, it will go through a transition stage. In this stage, both filters participate in the filtration and purification. As the sliding bracket 18 slides, the interception area of one filter becomes larger and larger, and the interception area of the other filter becomes smaller and smaller.

[0076] After the original connecting pipe 19 is completely separated from the pipe joint 8, the maintenance plug 11 is opened by the extension of 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 replacing the new filter element, the maintenance plug 11 can be closed again by the retraction of the double-headed telescopic electric cylinder 13.

[0077] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to this process, method, article or device.

[0078] The above describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto.
