Description

Technical Field

[0001] The present invention relates to the technical field of separation of solid-liquid mixtures or solutions in chemical industry, environmental protection, pharmacy, food, etc., and in particular to a device and method for separating substances trapped by a moving barrel-shaped medium. Background Art

[0002] Filtration is an operation in which the liquid (or gas) in a fluid (a suspension or a heat-generating or non-heat-generating gas containing solid particles) passes through a medium under the action of a driving force or other external force, and the solid particles and other substances are retained by the filter medium, thereby separating the solids and other substances from the liquid (or gas). It is a common method of separating substances.

[0003] Distillation is a method of separating two liquid substances by utilizing the difference in boiling points. If there are heat-sensitive components in the liquid components, they will be easily destroyed. Therefore, this separation method also has certain limitations and high energy consumption.

[0004] Existing separation technologies that use media to retain substances often suffer from the problem of retained material (commonly known as filter cake) clogging or hindering the continued passage of the separated material through the media. This consumes a lot of energy and reduces separation efficiency. Cleaning the filter cake also requires interrupting equipment operation, preventing continuous operation and severely impacting work efficiency. Distillation processes are even more energy-intensive and unsuitable for heat-sensitive substances, limiting the scope and continuity of separation projects.

[0005] At present, the tubular ceramic membrane separation media available on the market are integrated. Due to the limitations of the production process of ceramic tube separation media, ceramic tube separation media are easy to break. The larger the ceramic tube, the easier it is to break. In order to reduce the possibility of its breakage, its thickness must be increased. When the thickness of the tube wall increases, the separation resistance will increase, affecting the overall separation effect of the device. Summary of the Invention

[0006] Therefore, the technical problem solved by the present invention is to overcome the defects of the existing technology of separating substances by retaining substances through media, such as the presence of retaining substances blocking or hindering the continuous passage of the separated substances through the media, and to solve the defects of high distillation energy consumption and unsuitability for heat-sensitive substances, as well as the defects of the existing tubular ceramic membrane separation medium being relatively thick and affecting the overall separation effect of the device, thereby providing a moving barrel-shaped medium retaining substance separation device and method.

When the barrel-shaped medium assembly moves, the substances intercepted by the barrel-shaped medium assembly are continuously displaced, making way for small substances to be separated, so that small substances or separation liquid can smoothly pass through the barrel-shaped medium assembly and enter the separation liquid storage chamber. The barrel-shaped medium assembly is assembled and sealed from a plurality of small pieces of medium; the small pieces of medium are small flat plates or small curved surfaces.

[0012] a mother liquid inlet pipe, connected to the mother liquid holding chamber, and adapted to input the mother liquid to be separated into the mother liquid holding chamber;

[0014] a mother liquid outlet pipe, connected to the mother liquid holding chamber, adapted to discharge the remaining mother liquid in the mother liquid holding chamber; and connected to the mother liquid inlet pipe, so that the mother liquid is continuously circulated and separated;

[0015] The stirring device is arranged inside the barrel-shaped medium component; the driving mechanism drives the barrel-shaped medium component and the stirring device to move simultaneously, thereby driving the mother liquid to separate.

[0016] To further optimize the technical solution, the barrel-shaped medium component is concentrically arranged with at least one layer, and each layer of the barrel-shaped structure is arranged with at least one section in the vertical direction.

[0017] Further optimizing the technical solution, the barrel-shaped structure is a vertical sheet barrel-shaped structure or a folding barrel-shaped structure;

[0018] And / or the barrel-shaped structure includes multiple layers of medium barrels, the height of each layer of medium barrels increases from the inside to the outside, or a liquid inlet is provided at the barrel mouth of each layer of medium barrels.

[0019] To further optimize the technical solution, the barrel-shaped structure is composed of a flat plate or small curved surface medium coated with a separation medium on at least one side; the small flat plate or small curved surface medium includes a porous ceramic support and a separation medium coated on the outer surface of the porous ceramic support; the flat plate or small curved surface medium is a single-layer flat plate or small curved surface medium or a tunnel-type flat plate or small curved surface medium with a separation channel in the middle.

[0020] Further optimizing the technical solution, a lip-shaped valve seal is provided between the stirring device and the mother liquid outlet pipe and / or between the barrel-shaped medium component and the mother liquid outlet pipe;

[0021] The lip-shaped valve seal includes a lip-shaped connecting component and a lip-shaped valve sealing portion; the upper part of the lip-shaped connecting component is provided with a narrow airflow slit, the lower part is provided with an airflow overflow hole, and the middle part is provided with a mother liquid channel; the lower end of the lip-shaped valve sealing portion is provided with an arc-shaped sealing valve; the side bottom end of the lip-shaped valve sealing portion forms a pressure difference on the airflow overflow hole to form a seal between the moving part and the fixed part; the top of the lip-shaped valve sealing portion is connected to the mother liquid outlet of the barrel-shaped medium component or the moving section component of the stirring device, and the lip-shaped valve seal is suitable for generating an airflow gap at the fitting position with the lip-shaped connecting component during rotation, and the airflow gap is connected to the airflow overflow hole.

[0022] The technical solution is further optimized, and the device is applied to sewage treatment or boiler circulating water treatment in PCB printed circuit board production or lithium extraction from salt lakes.

[0023] A method for separating substances retained by a moving barrel-shaped medium, wherein a plurality of small pieces or blocks of medium are assembled and sealed into a barrel-shaped medium assembly to reduce the thickness of the barrel-shaped medium assembly;

[0024] The method comprises the following steps: the mother liquid is introduced into the interior of the barrel-shaped medium component, and the movement of the barrel-shaped medium component is used to continuously displace the substances intercepted by the barrel-shaped medium component, thereby making way for the small substances to be separated, thereby achieving self-cleaning of the barrel-shaped medium component and separation of the mother liquid.

[0025] To further optimize the technical solution, the movement of the barrel-shaped medium component causes the mother liquor to continuously flush the surface of the barrel-shaped medium component, the separated material continuously flows out, the mother liquor continuously circulates in and out, and the retained material on the surface of the barrel-shaped medium component continuously moves and displaces without being deposited on the barrel-shaped medium component.

[0026] Further optimizing the technical solution, the movement of the barrel-shaped medium assembly is controlled by a driving mechanism controlled by a controller, so that the speed of the barrel-shaped medium assembly is fast or slow, or forward or reverse or intermittent forward and reverse, thereby adjusting the self-cleaning flushing force to increase or decrease; thereby forming a uniform or tidal cleaning method;

[0027] And / or when the barrel-shaped medium assembly moves, the stirring device moves simultaneously to enhance the effect of cleaning the barrel-shaped medium assembly.

[0028] To further optimize the technical solution, the mother liquor is separated by at least one layer of barrel-shaped medium components.

[0029] To further optimize the technical solution, when the mother liquid enters the lip-shaped connecting component from the moving section of the mother liquid outlet pipe and the barrel-shaped medium component does not move, the mother liquid at the mother liquid outlet presses the lip-shaped valve sealing component outward, causing the lip-shaped opening to expand outward, so that the airflow overflows the small hole and the bottom valve of the lip-shaped valve sealing component forms a pressure difference, resulting in a sealed state;

[0030] When the barrel-shaped medium component and the moving section of the mother liquid outlet pipe move, a gap is generated between the lip-shaped valve sealing component and the spherical surface of the head of the fixed tube of the mother liquid outlet pipe, and air enters and is discharged through the air flow overflow hole at the bottom of the head of the fixed tube of the mother liquid outlet pipe. At the same time, the thin lip-shaped opening at the bottom of the sealing ring is squeezed and closed by the internal liquid, thereby achieving an air sealing effect.

[0031] The technical solution of the present invention has the following advantages:

[0032] 1. The present invention provides a method for separating substances retained by a moving barrel-shaped medium. The method utilizes the movement of the barrel-shaped medium assembly to continuously displace the substances retained by the barrel-shaped medium assembly, thereby clearing a path for small substances to be separated, thereby achieving self-cleaning of the barrel-shaped medium assembly. The separated substances can be discharged through the separation liquid outlet pipe, and the unseparated mother liquid and substances flushed from the inside of the barrel-shaped medium assembly by the mother liquid are discharged through the mother liquid outlet pipe. The separation liquid is continuously removed and the mother liquid is continuously circulated in and out, so that the separated substances are continuously in motion and do not deposit on the barrel-shaped medium assembly. Furthermore, the substances retained by the barrel-shaped medium assembly of the present invention are displaced due to the continuous movement, so there will be no blockage or obstruction of the separation substances from passing through the medium, thereby ensuring the separation efficiency of the barrel-shaped medium assembly, and there is no shutdown for cleaning the retained substances. This overcomes the defects of the existing sheet-shaped ceramic media that cannot operate continuously and the defects of distillation separation.

[0033] The original fixed tubular medium self-cleaning method is improved to a moving medium composed of several small pieces of medium. This overcomes the problem of the original tubular medium's thickness being unable to be reduced. Each small piece of medium can be produced independently, allowing each piece to be made very thin. The overall thickness of the assembled small pieces is significantly lower than that of the tubular medium. During mother liquor separation, the resistance of the mother liquor passing through the small pieces is greatly reduced compared to the tubular medium, while the separation area is increased, thereby enhancing the overall separation efficiency of the device and significantly increasing the output of separated liquid or separated material per unit time.

[0034] 2. Compared with static separation media, the present invention has the advantages of large separation medium area, low energy consumption and large flux. It can be widely used in chemical industry, pharmaceutical industry, environmental protection, papermaking, printing and dyeing, metallurgy, food, sewage sludge treatment, polymer material synthesis and other fields. It has the characteristics of wide application range, low cost and significant economic benefits.

[0035] 3. The present invention provides a method for separating substances retained by a moving barrel-shaped medium. The cleaning efficiency of the barrel-shaped medium component can be achieved by controlling the movement state of the barrel-shaped medium component. The movement state of the barrel-shaped medium component can then be selectively controlled according to cleaning needs to increase or decrease the flushing force of the self-cleaning.

[0036] 4. The present invention provides a moving barrel-shaped medium intercepting material separation device, in which the barrel-shaped medium components are arranged in at least one layer in the concentric direction, and each layer of the barrel-shaped medium components is provided with at least one section in the vertical direction. The axial inner layer of the barrel-shaped medium component temporarily stores the unseparated mother liquid, and the outer shell component temporarily stores the separated liquid. As the number of layers and sections of the barrel-shaped medium component increases, the contact area between the mother liquid and the barrel-shaped medium component increases, thereby enhancing the separation effect of the mother liquid. The present invention "fragments" the medium, i.e., divides it into multiple layers, thereby increasing the separation area and further reducing the thickness of the sheet medium, thereby reducing the separation resistance.

[0037] 5. The present invention provides a moving barrel-shaped medium intercepting material separation device, in which a lip-shaped valve-type seal is provided between the stirring device and the mother liquid outlet pipe and / or between the barrel-shaped medium assembly and the mother liquid outlet pipe. When the mother liquid enters the interior of the lip-shaped connecting component from the moving section of the mother liquid outlet pipe, and the barrel-shaped structure does not move, the mother liquid at the mother liquid outlet squeezes the lip-shaped valve seal component outward, causing its lip-shaped opening to expand outward, so that the airflow overflow hole and the bottom valve of the lip-shaped valve seal component form a pressure difference, and the state is sealed. When the barrel-shaped structure and the moving section of the mother liquid outlet pipe move, a certain gap is generated between the lip-shaped valve seal component and the spherical surface of the head of the fixed tube of the mother liquid outlet pipe, and air enters and is discharged through the airflow overflow hole at the bottom of the fixed tube head of the mother liquid outlet pipe. At the same time, the thin lip-shaped opening at the bottom of the sealing ring is squeezed and closed by the internal liquid, achieving the effect of air sealing. Such sealing greatly reduces the wear of the sealing ring and improves the life and reliability of the sealing ring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the meanings of the above terms in the present invention based on specific circumstances.

[0055] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] Example 1

[0057] This embodiment discloses a moving barrel-shaped medium retained material separation device, comprising: a housing 2 , a barrel-shaped medium assembly, a driving mechanism, a separation liquid outlet pipe 3 , and a mother liquid outlet pipe 4 .

[0058] A plurality of legs 6 are provided at the bottom of the housing 2 to support the entire device.

[0059] The barrel-shaped media assembly forms a mother liquid holding chamber within the barrel-shaped media assembly, which is located within the outer shell 2. A storage chamber for temporarily storing the separation liquid is formed between the barrel-shaped media assembly and the outer shell 2. As the barrel-shaped media assembly moves, the material trapped by the barrel-shaped media assembly is continuously displaced, clearing a path for small particles to be separated. These small particles or the separation liquid can then pass smoothly through the barrel-shaped media assembly into the separation liquid storage chamber.

[0060] The driving mechanism is suitable for driving the barrel-shaped medium component to move so as to separate the mother liquid in the mother liquid holding chamber.

[0061] The mother liquid inlet pipe 1 is communicated with the mother liquid holding chamber, and the mother liquid inlet pipe 1 is suitable for inputting the mother liquid to be separated into the mother liquid holding chamber.

[0062] The separation liquid outlet pipe 3 is connected to the separation liquid storage chamber, and the separation liquid outlet pipe 3 is suitable for discharging the separation liquid or separation substance or small substance in the separation liquid storage chamber.

[0063] The mother liquid outlet pipe 4 is connected to the mother liquid holding chamber and is suitable for discharging the remaining mother liquid in the mother liquid holding chamber. The mother liquid outlet pipe 4 is connected to the mother liquid inlet pipe 1 to enable the mother liquid to be continuously circulated and separated.

[0064] like Figure 1 As shown, the above-mentioned moving barrel-shaped medium-retained material separation device performs mother liquor separation. During mother liquor separation, the mother liquor to be separated enters the mother liquor holding chamber through the mother liquor inlet pipe 1. The drive mechanism drives the barrel-shaped medium assembly to move, causing the mother liquor in the mother liquor holding chamber to continuously contact the barrel-shaped medium assembly, thereby separating the mother liquor. As the barrel-shaped medium assembly moves, the material retained by the barrel-shaped medium assembly is continuously displaced, clearing a path for small molecules in the mother liquor to be separated, thereby achieving self-cleaning of the barrel-shaped medium assembly. The separated liquid is discharged through the separated liquid outlet pipe 3, while the unseparated mother liquid and the material flushed from the barrel-shaped medium assembly by the mother liquid are discharged through the mother liquid outlet pipe 4. The separated liquid continuously flows out, and the mother liquid continuously circulates in and out. The material retained by the barrel-shaped medium assembly is continuously displaced and does not deposit on the barrel-shaped medium assembly. Consequently, the barrel-shaped medium assembly does not clog or hinder the passage of the separated solvent or separated material through the medium, greatly improving separation efficiency. There is no need to shut down the device to clean the separated material, allowing for continuous operation of the device.

[0065] The aforementioned moving barrel-shaped medium retained material separation device further includes a stirring device disposed within the barrel-shaped medium assembly. The stirring device includes a stirring shaft and a stirring paddle 16 disposed on the stirring shaft. The stirring paddle 16 drives the mother liquid to be separated within the barrel-shaped medium assembly to move, thereby enhancing the washing force, making the mother liquid to be separated have a stronger cleaning effect on the barrel-shaped medium assembly, and further improving the cleaning effect on the retained material.

[0066] The drive mechanism includes a motor 5 and a linkage assembly, which is connected to the motor 5. The linkage assembly can be directly connected to the barrel-shaped medium assembly or connected to the barrel-shaped medium assembly through a stirring device. When the linkage assembly is connected to the barrel-shaped medium assembly through the stirring device, one embodiment of the linkage assembly is as follows: the linkage assembly includes a driving gear, a driven gear, and a chain. The driven gear is disposed on the stirring shaft. When the motor drives the driving gear to rotate, the stirring shaft is driven to rotate.

[0067] The present invention can use the following methods to separate the mother liquor: 1. The driving mechanism drives the barrel-shaped medium component to move, thereby driving the mother liquor to separate. 2. Or the barrel-shaped medium component is stationary, and the driving mechanism drives the stirring device to stir the mother liquor, thereby driving the mother liquor to separate. 3. Or the driving mechanism drives the barrel-shaped medium component and the stirring device to move at the same time, thereby driving the mother liquor to move for separation. When the above methods are used, when the barrel-shaped medium component and / or the stirring device moves, the retained substances can leave the surface of the barrel-shaped medium component, making it easy for substances that cannot pass through the barrel-shaped medium component to be passively displaced, thereby making way for the small molecule solvent substances to be separated.

[0068] To address the aforementioned technical issues, the barrel-shaped media assembly in this embodiment can be assembled and sealed from several small pieces or blocks of media. This improves the original fixed tubular media fluid self-cleaning form to a moving media form assembled from several small pieces of media. This overcomes the problem of the original tubular media thickness being unable to be thinned. Each small piece of media can be produced independently, allowing each piece of media to be made very thin. The overall thickness of the assembled small pieces of media is significantly lower than that of the tubular media. During mother liquor separation, the resistance of the mother liquor passing through the small pieces of media is significantly reduced compared to the tubular media, while the separation area is increased, thereby enhancing the overall separation efficiency of the device and significantly increasing the output per unit time.

[0069] In a specific embodiment, the small-piece media is a small flat plate or small curved surface media. The small flat plate or small curved surface media comprises a porous ceramic support and a separation medium coated on the surface of the porous ceramic support. The separation medium can be coated on the inner and / or outer surface of the porous ceramic support. In other words, the barrel-shaped media assembly of the present invention is composed of a plurality of sheet-shaped ceramic membranes. The small flat plate or small curved surface media comprises a 1-5 mm porous ceramic support and is coated with a layer of separation medium with a uniform pore size to control the size of the molecules, molecular clusters, or particles that pass through the separation.

[0070] As a specific embodiment, the barrel-shaped medium assembly in this embodiment is configured as a barrel-shaped structure, and the outer shell 2 is also a barrel-shaped structure. The small pieces of media in this embodiment are divided into vertical sheet separation media 7 and bottom sheet separation media 8. The small pieces of media are assembled in sequence and surrounded by a barrel-shaped structure, and then connected with a frame sealing ring. The ends of the vertical sheet separation media 7 in this embodiment are connected to each other to form a polygonal barrel form, and the bottom sheet separation media 8 is fan-shaped. The bottom sheet separation media 8 are spliced ​​into a circle and are located below the vertical sheet separation media 7. The vertical sheet separation media 7 and the bottom sheet separation media 8 are both ceramic separation media.

[0071] As a specific embodiment, the barrel-shaped structure is composed of a separation medium flat plate or small curved surface medium with a coating on at least one side, and the flat plate or small curved surface separation medium 9 is a single-coated flat plate or small curved surface medium or a tunnel-type double-coated flat plate or small curved surface medium with a separation channel in the middle. Figure 7 As shown, the flat plate or small curved surface separation medium is a single layer flat plate or small curved surface medium 91; Figure 8 As shown, the flat plate or small curved surface separation medium is a tunnel-type flat plate or small curved surface medium with a separation channel in the middle. The flat plate or small curved surface medium is a tunnel-type double-coated flat plate or small curved surface medium. A plurality of tunnel openings 921 are opened in the middle of the tunnel-type double-sided flat plate or small curved surface medium 92, and the separation liquid can be discharged through the tunnel openings 921.

[0072] The barrel-shaped media components are arranged in at least one layer (or two, or more), each layer comprising at least one section. The inner barrel-shaped media components temporarily store unseparated mother liquor, while the outer barrel-shaped media components temporarily store separated liquid. As the number of layers and sections of the barrel-shaped media components increases, the contact area between the mother liquor and the barrel-shaped media components increases, thereby enhancing the separation effect.

[0073] like Figure 2 As shown, the barrel-shaped medium assembly in this embodiment uses rectangular sheet separation medium as the facade, connected by a frame sealing ring to form a barrel shape, and uses fan-shaped sheet medium as the barrel bottom, and the outer barrel is divided into three sections and one layer. The bracket that carries the sheet separation medium is made of 316L stainless steel or corrosion-resistant non-metal. The inner layer of rectangular sheet separation medium temporarily stores the unseparated mother liquid, and the cavity between the rectangular sheet separation medium and the outer shell temporarily stores the separation liquid that has passed through the medium. The rectangular sheet separation medium is driven by a motor to rotate forward or reverse, slow for 3 minutes and fast for 1 minute to continuously clean the medium. In this embodiment, flat or small curved ceramic separation media are used, and the thickness is 3mm. The total area of ​​the medium used is 0.68m 2 The medium pore diameter is 200nm, and the total flux is 15Kg per hour. The liquid medicine used is the primary extract of Xiaoer Qingfei Oral Liquid.

[0074] As a further improved embodiment, special lip-shaped valve seals are used at the connection points between the moving and fixed components. A central axis lip-shaped valve seal A14 is installed between the barrel-shaped medium assembly and the mother liquid outlet pipe 4, and a central axis lip-shaped valve seal B15 is installed between the stirring device and the mother liquid outlet pipe 4.

[0075] like Figure 9The figure shows the structure of a central axis lip-shaped valve seal B. The lip-shaped valve seal in this figure includes a lip-shaped connecting member and a lip-shaped valve sealing member. The lip-shaped connecting member is thick and resistant to deformation; the lip-shaped valve sealing member is thin and deforms with the pressure difference between the inside and outside of the barrel tube. When compressed, the valve expands.

[0076] like Figure 10 As shown in the figure, this figure is a cross-sectional view of the central axis lip-shaped valve-type seal B. It can be seen from the figure that the mother liquid outlet pipe 4 has a mother liquid outlet pipe moving section 42 and a mother liquid outlet pipe fixed section 41. The mother liquid outlet pipe moving section 42 is connected to the stirring device or the barrel-shaped medium component, that is, the mother liquid outlet pipe moving section 42 can move. The mother liquid outlet pipe fixed section 41 has an airflow overflow hole 43, and the central part of the lip-shaped connecting component is penetrated by a mother liquid channel. The lower part of the valve sealing component is set to an arc shape that is compatible with the mother liquid outlet section fixed section. It relies on the negative pressure of the airflow overflow hole 43 to make the valve seal more tightly and seal. An annular groove is provided on the side of the lip-shaped valve sealing component, and an annular protrusion fixed to the annular groove is provided on the mother liquid outlet pipe moving section 42, thereby making the lip-shaped valve sealing component tightly connected to the mother liquid outlet pipe moving section 42.

[0077] The working principle of the lip-shaped valve seal is as follows: when the medium barrel is not moving, when the mother liquid flows from the mother liquid outlet pipe moving section 42 to the mother liquid outlet pipe fixed section, the central axis lip-shaped connecting component is tightly connected to the mother liquid outlet pipe moving section 42, and the mother liquid flowing through the mother liquid outlet pipe fixed section 41 will squeeze the lip-shaped valve sealing component outward, and the bottom of the lip-shaped valve sealing component will cause the airflow to overflow the small hole 43 to form a pressure difference and tightly fit the inner wall of the fixed section, forming a sealed state; when the medium barrel moves, a certain gap is generated between the lip-shaped valve sealing component and the spherical surface of the outlet pipe fixed pipe head, so that air enters and is discharged through the airflow overflow small hole 43 at the lower part of the outlet pipe fixed pipe head. At the same time, the lower part of the valve sealing ring is squeezed by the internal liquid, and the airflow overflows from the airflow overflow small hole 43. The external pressure of the valve sealing ring is less than the internal pressure, and the valve sealing ring is tightly attached to the inner side of the fixed section to achieve sealing. At the same time, the airflow enters from the narrow slit at the upper end to form an air film, which greatly reduces the wear of the sealing ring and improves the service life and reliability of the sealing ring.

[0078] Example 2

[0079] Based on Example 1, this example discloses a moving barrel-shaped medium intercepting substance separation device. The difference between this example and Example 1 is that the specific shape of the barrel structure is different. Figure 5As shown, this embodiment is a folded medium barrel structure, which is an example for expanding the surface area of ​​the medium. The vertical sheet separation media 7 in this embodiment are sequentially spliced ​​into a folded shape, and an acute angle is formed between each vertical sheet separation medium 7. The two adjacent vertical sheet separation media 7 are of the same length and are symmetrically arranged with the connecting line of their intersection. The bottom sheet separation medium 8 is a fan-shaped flat plate or a small curved surface, and each bottom sheet separation medium 8 is sequentially spliced ​​into a circle. A connecting separation medium 17 is also provided between the vertical sheet separation medium 7 and the bottom sheet separation medium 8. The connecting separation medium 17 is set in a triangle or polygon. The connecting separation medium 17 in this embodiment is arranged in the same plane as the bottom sheet separation medium 8. The cross-section of the barrel structure is tooth-shaped, and the barrel structure is divided into two sections at the top and bottom. The surface area of ​​the medium in the barrel structure is larger than that in Example 1. The barrel structure can increase the contact area with the mother liquor. Under the same volume of the equipment, its effective separation area is 2.14m 2 .

[0080] like Figure 3 and Figure 4 As shown, this embodiment incorporates a bearing on the barrel lid to prevent the lid from moving. The mother liquid inlet pipe 1, mounted on the barrel lid, rotates via the bearing. The mother liquid inlet pipe 1 is coaxially arranged with the mother liquid outlet pipe 4. A mother liquid inlet hole 44 is defined in the mother liquid inlet pipe 1, through which the mother liquid is discharged into the barrel. A mother liquid inlet pipe partition 45 is provided between the mother liquid inlet pipe 1 and the mother liquid outlet pipe moving section 42. The mother liquid outlet pipe moving section 42 also has an outlet hole, through which the mother liquid in the barrel is delivered to the mother liquid outlet pipe moving section 42 for discharge. Furthermore, the mother liquid inlet pipe 1 and the separated liquid outlet pipe 3 are not coaxially arranged.

[0081] In this example, the above-mentioned liquid was used as a control experiment, and the effective separation medium area was increased threefold, and the separation flux reached 30 kg per hour.

[0082] Example 3

[0083] like Figure 6 As shown, this embodiment discloses a moving barrel-shaped medium intercepting material separation device, and this embodiment improves the folded medium moving separation device in Example 2.

[0084] The vertical sheet separation media 7 in this embodiment are spliced ​​in sequence into a foldable shape. The barrel structure in this embodiment is an improved folded medium barrel structure. When the barrel structure rotates, the force it drives to move the retained substances and mother liquid is stronger, further improving the cleaning effect of the barrel structure.

[0085] The vertical sheet separation medium 7 is divided into a first vertical sheet separation medium (the resistance surface in the forward direction of the barrel-shaped structure) and a second vertical sheet separation medium (the non-resistance surface in the forward direction of the barrel-shaped structure). The first vertical sheet separation medium and the second vertical sheet separation medium have the same height and different widths (the second vertical surface is smaller than the first vertical surface), and are spliced ​​in sequence. Compared with Example 2, the resistance of the improved folded medium barrel structure is reduced when it moves. The bottom sheet separation medium 8 is a fan-shaped flat plate or a small curved surface, and each bottom sheet separation medium 8 is spliced ​​into a circle in sequence. A connecting separation medium 17 is also provided between the vertical sheet separation medium 7 and the bottom sheet separation medium 8. The connecting separation medium 17 is divided into a first connecting separation medium and a second connecting separation medium, which are matched and connected with the first vertical sheet separation medium and the second vertical sheet separation medium respectively. There is a certain angle between the first connecting separation medium and the second connecting separation medium and they are recessed downward, thereby increasing the effective separation medium area of ​​the barrel as a whole. Under the same outer barrel size, the maximum effective separation medium area of ​​the inner barrel is 3.11m 2 , the rotation speed is accelerated, the flux and efficiency are greatly improved. Using the above-mentioned liquid medicine for comparative test, the flux per hour can be increased to 45Kg.

[0086] Example 4

[0087] Based on Example 1, this example discloses a moving barrel-shaped medium intercepting substance separation device. This example is a three-layer three-segment separation medium barrel, and an example of mixed use of single-coated and double-coated flat or small curved surface media. The combination of multiple layers and multiple segments of the thinnest media can be made according to the volume of the medium barrel. This is very beneficial for easy preparation of flat or small curved surface media, minimizing the skeleton, and minimizing separation resistance. Figure 11 As shown, in this embodiment, a first layer of separation medium barrels 10, a second layer of separation medium barrels 11, and a third layer of separation medium barrels 12 are sequentially arranged within the housing 2 from the inside out. The first layer of separation medium barrels 10 is composed of three sections of double-coated flat or slightly curved medium, the second layer of separation medium barrels 11 is composed of double-coated separation medium, and the third layer of separation medium barrels 12 is composed of one, two, or three sections of single-coated sheet-like separation medium. Separation liquid outlet channels 13 are respectively defined at the bottom of the second and third layers of separation medium barrels 11, 12.

[0088] As a further improved embodiment, the barrel-like structure comprises multiple layers of nested separation barrels, with the height of each layer increasing from the inside out. This means the barrel-like structure is provided with an inner ring and an outer ring, with the outer ring being taller than the inner ring. Alternatively, multiple liquid inlets are provided at the same height. In this embodiment, the barrel-like structure is multi-layered, with the inner ring being the lowest and the outer ring being the highest. This facilitates the introduction of mother liquid into each layer, ensuring maximum separation efficiency.

[0089] As an alternative embodiment, the mother liquid inlet pipe 1 can transport the mother liquid to each layer of separation barrels through branch inlet pipes, thereby achieving separate liquid inflow to each layer of separation barrels.

[0090] This embodiment can also perform multi-aperture separation by having different layers (rings) of media with different pore sizes. The outlets at the lower end of the barrel composed of different media pores are connected to different circular grooves, and can flow out separately for separate treatment. This is particularly suitable for gold panning processes in metallurgy or similar distillation processes, and can also be used for the fractionation of different components in petrochemicals.

[0091] Example 5

[0092] Based on any one of Examples 1 to 4, this embodiment discloses a method for separating substances retained by a moving barrel-shaped medium. The method is to pass the mother liquor into the interior of the barrel-shaped medium component, and utilize the movement of the barrel-shaped medium component to make the substances retained by the barrel-shaped medium component continuously move and displace, thereby making way for the solvent or small molecule substances or separation substances to be separated, so as to achieve self-cleaning of the barrel-shaped medium component and separation of the mother liquor.

[0093] In the above-mentioned method for separating substances retained by a moving barrel-shaped medium, when separating the mother liquid, the mother liquid to be separated enters the mother liquid holding chamber through the mother liquid inlet pipe 1, and the driving mechanism drives the barrel-shaped medium component to move, so that the mother liquid in the mother liquid holding chamber continuously contacts the barrel-shaped medium component, thereby separating the mother liquid. When the barrel-shaped medium component moves, the substances retained by the barrel-shaped medium component are continuously moved and displaced, making way for small molecules in the mother liquid to be separated, thereby achieving self-cleaning of the barrel-shaped medium component. The separation liquid can be discharged through the separation liquid outlet pipe 3, and the unseparated mother liquid and the retained substances flushed from the inside of the barrel-shaped medium component by the mother liquid are discharged through the mother liquid outlet pipe 4. The separation liquid continuously flows out, and the mother liquid continuously circulates in and out, so that the substances retained by the barrel-shaped medium component are also continuously moved and displaced, and are not deposited on the barrel-shaped medium component. Furthermore, the substances retained by the barrel-shaped medium component will not clog or hinder the passage of the solvent or separated matter through the medium after separation, which greatly improves the separation efficiency. In addition, there is no need to shut down the machine to clean up the retained substances, so that the device can operate continuously.

[0094] In order to solve the sealing problem between the barrel-shaped medium assembly and the mother liquid outlet pipe 4 and to avoid wear of the sealing ring between the barrel-shaped medium assembly and the mother liquid outlet pipe 4, in this embodiment, when the mother liquid is discharged from the mother liquid outlet pipe 4 and the barrel-shaped medium assembly is not moving, a seal is formed between the barrel-shaped medium assembly and the mother liquid outlet pipe 4; when the mother liquid is discharged from the mother liquid outlet pipe 4 and the barrel-shaped medium assembly is moving, an air seal is formed between the barrel-shaped medium assembly and the mother liquid outlet pipe 4.

[0095] More specifically, when the mother liquid enters the lip-shaped connecting component from the moving section of the mother liquid outlet pipe and the barrel-shaped medium component does not move, the mother liquid at the mother liquid outlet presses the lip-shaped valve sealing component outward, causing the lip-shaped opening to expand outward, resulting in a pressure difference between the airflow overflowing the small hole and the bottom valve of the lip-shaped valve sealing component, thus forming a sealed state;

[0096] When the barrel-shaped medium component and the moving section of the mother liquid outlet pipe move, a gap is generated between the lip-shaped valve sealing component and the spherical surface of the head of the fixed tube of the mother liquid outlet pipe, and air enters and is discharged through the air flow overflow hole at the bottom of the head of the fixed tube of the mother liquid outlet pipe. At the same time, the thin lip-shaped opening at the bottom of the sealing ring is squeezed and closed by the internal liquid, thereby achieving an air sealing effect.

[0097] As a further improved embodiment, the movement of the barrel-shaped media assembly is driven by a controller-controlled drive mechanism, with various rotational speeds, including forward, reverse, and intermittent forward and reverse rotations, to increase or decrease the self-cleaning flushing force. Increasing or decreasing the rotational speed allows the barrel-shaped media assembly to be continuously cleaned by the mother liquid, thereby achieving a variety of uniform or turbulent cleaning modes. The cleaning efficiency of the barrel-shaped media assembly in this embodiment can be achieved by controlling the movement of the barrel-shaped media assembly, thereby enabling selective control of the movement of the barrel-shaped media assembly based on cleaning needs.

[0098] As a further improved embodiment, when the barrel-shaped medium assembly moves, the stirring device moves simultaneously to enhance the effect of cleaning the barrel-shaped medium assembly.

[0099] In the above-mentioned method for separating substances retained by a moving barrel-shaped medium, after the mother liquid to be separated is introduced into the interior of the barrel-shaped medium component, the mother liquid passes through at least one layer of the barrel-shaped medium component for separation. After separation, the separated substance (liquid) continuously flows out, and the mother liquid continuously circulates in and out, so that the substances remaining on the inner surface of the barrel-shaped medium component are continuously moved and displaced and are not deposited on the barrel-shaped medium component.

[0100] Example 6

[0101] This embodiment is the application of any one of Examples 1 to 4 in wastewater treatment during the production of printed circuit boards (PCBs). For wastewater treatment involving multiple processes and multiple pollutants, wastewater classification and timely treatment should be adopted to simplify wastewater treatment and reduce enterprise costs. The wastewater from each step of the pre-treatment process, including oil removal, four-stage water washing, micro-etching, and four-stage water washing, is treated separately, and what can be recycled is recycled. The wastewater from the oil removal, four-stage water washing, micro-etching, and four-stage water washing processes in the development and etching process is treated separately; and the wastewater from the acid washing, four-stage washing, alkaline washing, four-stage washing, and deionized water washing steps in the acidification process is treated separately. This changes the existing unified discharge and unified treatment model, which will greatly alleviate the high cost and low efficiency of water treatment in PCB production. It is particularly suitable for copper plating, pattern plating, outer layer etching, and gold and tin plating processes in surface treatment. Each step only requires a small medium-moving self-cleaning material separation device to solve the problem. The medium motion type self-cleaning material separation device in Examples 1 to 5 is used for sewage treatment to meet the standards of industrial water. By adding different precipitants in different separation barrels, multiple precious metals can be recovered by one machine.

[0103] This embodiment is the application of any one of Embodiments 1 to 4 in boiler circulating water treatment.

[0104] To descale boiler cooling water and effectively reduce TDS, a special soda ash calcium and magnesium removal device is first used, and then combined with the moving barrel medium interception material separation device disclosed in the present invention to remove newly generated calcium carbonate and magnesium salts. The circulating water with increased TDS is then subjected to salting out treatment and recirculated to the special separator of this device for salt separation, which can effectively reduce the boiler circulating water by 10-500 PPM.

[0105] Example 8

[0106] This embodiment is the application of any one of Examples 1 to 4 in extracting lithium from salt lakes.

[0107] The present invention utilizes a moving barrel-shaped medium interception and separation device to produce concentrated brine. After simple acid removal of calcium and magnesium, lithium extraction using a manganese dioxide-lithium molecular sieve yields 99.5% lithium (calculated as lithium carbonate). This device can be used in a multi-stage combination to produce concentrated brine, followed by extraction with tributyl phosphate, yielding 99.2% (calculated as lithium carbonate) of concentrated brine.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
