Description

Technical Field

[0001] The utility model belongs to the technical field of resin cleaning, and particularly relates to a resin turning and washing tank and a resin cleaning device for cleaning resin products such as adsorption resin. Background Art

[0002] Adsorption resin is a porous, high-surface-area spherical material that is often used as an adsorbent in hemoperfusion devices. Before being loaded into the hemoperfusion device, the adsorption resin needs to be cleaned to remove foreign matter on the surface of the resin to ensure the safety of hemodialysis treatment. Currently, the resin is mostly cleaned by stirring. The resin is poured into a container, stirred and tumbled manually or mechanically, and water is added during the stirring process for repeated rinsing. This traditional stirring and cleaning method has the following problems: ① When using a stirring rod to stir the resin, the stirring rod will come into contact with the resin, which may damage the resin, causing the resin to break and reduce the adsorption performance of the resin. ② During the cleaning process, the resin is in a tightly packed state in the container, the cleaning water and the resin are not in sufficient contact, and the cleaning efficiency is low. In addition, how to reduce water consumption during the cleaning process is also an issue that needs to be considered. Utility Model Content

[0003] The utility model aims to provide a resin turning tank and a resin cleaning device with good cleaning effect and high cleaning efficiency.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A resin cleaning tank comprises: a tank body, wherein an air / water inlet is provided at the bottom of the tank body; a filter cartridge is arranged in the tank body, an annular cavity is formed between the side wall of the filter cartridge and the inner wall of the tank body, a cavity is formed between the bottom of the filter cartridge and the bottom of the tank body, and the air / water inlet is connected to the cavity and is used to spray clean air and water into the tank body.

[0006] As can be seen from the above technical solution, the utility model sets a filter cartridge in the tank body, dividing the interior of the tank body into an inner cavity for placing resin and an annular outer cavity for filtering foreign matter. An air / water inlet is set at the bottom of the tank body, and the air / water inlet is connected to the cavity between the bottom of the filter cartridge and the bottom of the tank body. The air / water inlet is used to spray high-speed air / water flow upward from the bottom, which has strong cleaning power. The high-speed gas-carrying water flow flushes the resin, ensuring the lifting and tumbling effect of the resin in the filter cartridge. A large gap can be maintained between the resins to avoid dense accumulation of resins, increase the cleaning and filtration area, and have high cleaning efficiency and good cleaning effect. It can effectively remove suspended matter, particulate solids and broken fine resin that enter the resin layer, solving the problems of resin blockage and poor cleaning effect in the existing technology. In addition, water flow is used to stir the resin instead of a stirring rod, reducing the loss of resin caused by stirring.

[0007] As for the resin flushing tank as described above, optionally, an annular overflow groove and a first liquid discharge port connected to the overflow groove are provided on the outer side of the tank body.

[0008] Furthermore, the overflow trough has an inner trough wall, an outer trough wall and a bottom wall; the top edge of the inner trough wall is lower than the top edge of the filter cartridge, and the top edge of the outer trough wall is higher than the top edge of the filter cartridge.

[0009] Furthermore, the bottom wall is inclined relative to a horizontal plane, and the first liquid discharge port is arranged at the lowest point of the bottom wall.

[0010] As described above, in the resin flushing tank, optionally, the outer side wall of the filter cartridge is provided with a plurality of guide plates arranged at intervals along the circumference; the guide plates are arc-shaped plates, and the guide plates are bent toward the center side of the filter cartridge.

[0011] A guide plate of a specific shape is set on the outer wall of the filter cartridge to serve as a confluence, thereby increasing the water flow guidance and guiding the fluid flowing out of the center to flow in a directional manner.

[0012] As described above, the resin flushing tank may optionally be provided with a second drain port in the middle of the tank body; and / or a third drain port may be provided on the tank body, the third drain port being provided at a groove formed by welding between the filter cartridge and the inner wall of the tank body.

[0013] Furthermore, the bottom plate of the filter cartridge is inclined relative to the horizontal plane, and the third liquid drain port is arranged at the lowest point of the groove.

[0014] The resin flushing tank as described above may optionally further include a first nozzle arranged at the bottom of the tank body, the first nozzle spraying water upward, and the direction of the sprayed water is toward the center of the filter cartridge; and / or, further include a second nozzle arranged at the middle and / or upper part of the tank body, the second nozzle spraying water in a horizontal direction, and the sprayed water is injected into the tank body along the tangent direction of the horizontal cross-section of the tank body.

[0015] Nozzles are set on the side walls and / or bottom walls of the tank. The nozzles at the bottom can increase the effect of churning the resin from bottom to top. The water flow impact force generated by the nozzles on the side walls can generate a bend circulation in the annular cavity, forming a spiral upward fluid direction and centrifugal force (external rotation) along the inner wall of the tank. The bend circulation can accelerate the discharge of foreign matter, drive the precipitated foreign matter to move upward, and finally flow out from the foreign matter discharge port at the top.

[0016] The utility model also provides a resin cleaning device, comprising the resin turning and washing tank as described above.

[0017] Furthermore, it also includes a circulating water storage tank, a clean air source, a clean water source, a water pump, a first filter, a second filter and a gas-liquid mixing pump; the outlet of the gas-liquid mixing pump is connected to the gas / water inlet through a first pipeline, and the inlet is connected to the clean air source and the clean water source through a second pipeline and a third pipeline respectively, and the inlet of the gas-liquid mixing pump is also connected to the outlet of the water pump through a fourth pipeline; the outlet of the circulating water storage tank is connected to the inlet of the water pump through a fifth pipeline, the first filter is arranged on the fifth pipeline, and the second filter is arranged on the fourth pipeline; the inlet of the circulating water storage tank is connected to the gas / water inlet and the drain port for discharging waste water after cleaning the resin in the tank body through a pipeline.

[0018] The resin cleaning device of the utility model is easy to operate and can reduce water consumption. The water used for cleaning the resin can be recycled and reused without the need to change the water many times. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is described in detail below in conjunction with the accompanying drawings. When describing the embodiments of the present invention in detail, for the sake of convenience, the drawings showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. It should be noted that the drawings are simplified and all use non-precise scales, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features; the terms "front", "back", "bottom", "upper", "lower", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two components; it can mean a wireless connection or a wired connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, the resin cleaning tank of this embodiment includes a tank body 1, a filter cartridge 2, and a cover plate 3. The upper end of the tank body 1 is open, allowing the resin to be cleaned to be added through the opening in the upper portion of the tank body 1. This embodiment is provided with support legs 4 for supporting the tank body 1. The support legs 4 are connected to the tank body 1, and the bottoms of the support legs 4 are provided with self-locking casters 5 to facilitate the movement of the cleaning tank.

[0028] The tank body 1 is a hollow cylinder with a space inside for placing the resin to be cleaned. The tank body 1 of this embodiment is a hollow cylinder with a conical bottom. The filter cartridge 2 is arranged inside the tank body 1. The outer diameter of the filter cartridge 2 is smaller than the inner diameter of the tank body 1, thereby forming an annular cavity between the filter cartridge 2 and the tank body 1. The resin is placed inside the filter cartridge 2 for cleaning. Filter holes are machined on the side walls and bottom walls of the filter cartridge 2. The pore size of the filter holes is smaller than the particle size of the resin, so that the resin will not leak out through the filter holes and enter the annular cavity between the filter cartridge 2 and the tank body 1.

[0029] In this embodiment, the bottom of the tank body 1 is conical, forming a cavity between the bottom wall of the filter cartridge 2 and the conical bottom of the tank body 1. An air / water inlet 1a is provided at the bottom of the tank body 1. The air / water inlet 1a is connected to the cavity between the bottom wall of the filter cartridge 2 and the bottom of the tank body 1. The air / water inlet 1a is connected to an external clean air source and clean water source via a pipeline. Clean air and water can be sprayed into the tank body 1 through the air / water inlet 1a, thereby generating a bottom-up water flow and air flow within the tank body 1 and the filter cartridge 2, driving the resin to tumble upward. During the tumbling process, the gaps between adjacent resins increase, thereby preventing the resin from accumulating at the bottom of the filter cartridge 2 and not being able to fully contact the clean water, improving cleaning efficiency, and also facilitating the rinsing of foreign matter from the resin surface. The filter holes on the side and bottom walls of filter cartridge 2 do not affect the injection of clean air and water from air / water inlet 1a into tank body 1, while also ensuring that resin does not leak from filter cartridge 2. Furthermore, the side and bottom walls of filter cartridge 2 can also be in the form of a filter screen. A cavity is formed between the bottom wall of filter cartridge 2 and the conical bottom of tank body 1. The resin within filter cartridge 2 does not directly accumulate on air / water inlet 1a, blocking it and affecting the injection of clean air and water from it. Furthermore, air / water inlet 1a is located at the bottom of tank body 1 and communicates with the cavity between the bottom wall of filter cartridge 2 and the bottom of tank body 1. The pipeline connecting to air / water inlet 1a is located outside tank body 1, eliminating the internal space of tank body 1 and facilitating pipeline connection, assembly, and subsequent inspection and maintenance.

[0030] The air / water inlet 1a is provided at the bottom of the tank body 1. The number of the air / water inlet 1a can be one or more. The provision of multiple air / water inlets 1a can expand the spray range of the water flow and the air flow, which is more conducive to improving the cleaning efficiency and cleaning effect. Figure 2 As shown, in this embodiment, three groups of air / water inlets 1a are arranged at regular intervals along the circumferential direction at the bottom of the tank body 1.

[0031] When the water flow and air flow pass through the air / water inlet 1a, the flow cross section suddenly shrinks due to the relatively small aperture of the air / water inlet 1a, which will increase the flow rate of the water flow and air flow, thereby increasing the impact force of the water flow and air flow, enhancing the cleaning power of the air / water flow, ensuring the lifting and tumbling effect of the resin, and further expanding the gap between the resins to improve the cleaning efficiency.

[0032] When the resin rolls and cleans inside the filter cartridge 2, the resin in the filter cartridge 2 is washed by the water flow rising from the bottom, and the foreign matter washed down spreads around with the water flow and passes through the filter holes of the filter cartridge 2 into the annular cavity between the filter cartridge 2 and the cylinder body 1.

[0033] Optionally, an overflow trough 6 is provided on the outside of the top of the tank body 1. The overflow trough 6 is an annular trough located on the outside of the top of the tank body 1. The overflow trough 6 comprises an inner trough wall 6a, an outer trough wall 6b, and a bottom wall 6c. In this embodiment, a cover plate 3 is provided, which covers the overflow trough 6. The cover plate 3 has a dustproof function. When the cover plate 3 is installed, it can prevent dust and foreign matter from falling into the tank body 1, thereby ensuring the cleanliness of the interior of the tank body 1. The inner trough wall 6a of the overflow trough 6 is part of the side wall of the tank body 1. The top edge of the inner trough wall 6a of the overflow trough 6 is lower than the top edge of the filter cartridge 2, and the top edge of the outer trough wall 6b of the overflow trough 6 is higher than the top edge of the filter cartridge 2. The top edge of the filter cartridge 2 is higher than the top edge of the inner trough wall 6a (tank body 1), which can prevent resin from being flushed out of the filter cartridge 2 during resin flushing. The top of the outer trough wall 6a of the overflow trough 6 is higher than the top of the filter cartridge 2, so that when the cover plate 3 is installed, it will not interfere with the filter cartridge 2 or the tank body 1.

[0034] The overflow trough 6 is provided with a first drain port 7 in communication with the overflow trough 6 for draining water, foreign matter, etc. that have flowed into the overflow trough 6. A plurality of first drain ports 7 can be provided, spaced apart along the circumference, so that water, foreign matter, etc. that have entered the overflow trough 6 can be promptly drained. Only one first drain port 7 can also be provided. In this embodiment, only one first drain port 7 is provided. To facilitate drainage, the bottom wall 6c of the overflow trough 6 of this embodiment is inclined. The bottom wall of the overflow trough 6 is inclined relative to the horizontal plane. The first drain port 7 is provided at the lowest point of the bottom wall 6c of the overflow trough 6, so that water can automatically flow along the inclined bottom wall 6c to the first drain port 7 for discharge, and the problem of water accumulation will not occur.

[0035] As a preferred embodiment of the present invention, a plurality of guide plates 8 are provided on the outer side wall of the filter cartridge 2 at intervals along the circumference. The guide plates 8 are arc-shaped plates that curve toward the center of the filter cartridge 2. The direction of the arc surface of the guide plates 8 aligns with the direction of the curved circulation within the annular cavity. This guides liquid and foreign matter flowing out of the filter cartridge 2 along the arc surface of the guide plates 8 and prevents foreign matter from flowing back into the filter cartridge 2.

[0036] Optionally, a second drain port 9 is provided on the tank body 1. The second drain port 9 is provided at a position higher than the bottom of the filter cartridge 2 and can be located in the middle of the tank body 1. One or more second drain ports 9 can be provided. When the resin to be cleaned is relatively small (less than a tank), the amount of water used to flush the resin can be reduced as appropriate. The water level only needs to be above the resin. The water used after cleaning does not need to flow out from the overflow tank 6 at the top of the tank body 1, but can be discharged directly from the second drain port 9. This can save water and reduce unnecessary waste. If the water level in the tank body 1 is lower than the setting height of the second drain port 9, it can be discharged directly from the air / water inlet 1a at the bottom of the tank body 1.

[0037] The filter cartridge 2 of this embodiment is fixed to the inner wall of the bottom of the tank body 1 by welding. A circle of grooves with an inverted triangular cross-section will be formed at the welding point between the bottom of the filter cartridge 2 and the inner wall of the tank body 1. Wastewater will accumulate in the grooves and cannot be discharged from the air / water inlet 1a at the bottom of the tank body 1. Further optionally, a third drain port 10 is also provided on the tank body 1 of this embodiment. The third drain port 10 is provided at the groove formed by welding between the filter cartridge 2 and the inner wall of the tank body 1, and the opening faces downward, so that the wastewater in the groove can be directly discharged. In order to facilitate the discharge of accumulated water from the third drain port 10, the bottom plate of the filter cartridge 2 can be designed to be inclined relative to the horizontal plane, so that the groove formed between the bottom of the filter cartridge 2 and the inner wall of the tank body 1 is also inclined. The third drain port 10 is provided at the lowest point of the groove to facilitate drainage.

[0038] To enhance the effect of churning the resin from bottom to top, in some embodiments, a first nozzle 11 is preferably disposed at the bottom of the (conical) tank body 1. The first nozzle 11 sprays water upward, and the direction of the water spray is toward the center of the filter cartridge 2. The water sprayed by the first nozzle 11 can drive the resin near the bottom and side walls of the filter cartridge 2 to surge from bottom to top and from outside to inside, thereby filling the blind spot of the air / water inlet 1a, increasing the impact force of the water flow, and improving the cleaning effect.

[0039] The first nozzle 11 can be located below the filter cartridge 2 or within the projection of the annular cavity between the filter cartridge 2 and the tank body 1 on the horizontal plane of the bottom of the tank body 1. When the first nozzle 11, which is located within the projection of the annular cavity between the filter cartridge 2 and the tank body 1 on the horizontal plane of the bottom of the tank body 1, sprays water, the effect of the curved circulation in the annular cavity driving the precipitated foreign matter to spiral upward can be enhanced, flushing the foreign matter into the overflow trough 6, thereby preventing the foreign matter from settling at the bottom of the annular cavity.

[0040] The first nozzles 11 can be evenly spaced along the circumference. In some embodiments, the first nozzles 11 are symmetrically positioned about the center of the tank body 1. The first nozzles 11 spray water upward at an angle, lifting foreign matter from the bottom of the annular cavity and preventing it from settling. The water discharge from the first nozzles 11 is directed toward the center of the filter cartridge 2. The sprayed water exerts an impact force on resin adhering to the filter cartridge 2, preventing excessive resin from adhering to the filter cartridge 2 and clogging the filter pores.

[0041] In other embodiments, a second nozzle 12 is provided in the middle and / or upper part of the tank body 1, and the second nozzle 12 is evenly spaced along the circumferential direction on the side wall of the tank body 1. The second nozzle 12 sprays water in a horizontal direction. The water sprayed by the second nozzle 12 is injected into the tank body 1 along the tangent direction of the horizontal cross section of the tank body 1, thereby forming a bend circulation in the annular cavity, generating a water flow that spirals upward along the inner wall of the tank body 1 and an outward rotating centrifugal force. The outward rotating centrifugal force can accelerate the precipitation of foreign matter in the filter cartridge 2 from the inside to the outside, and the bend circulation can drive the precipitated foreign matter to spiral upward and flow into the overflow tank 6 from the top. The second nozzle 12 can be set at different heights in the middle of the tank body 1, and the spraying direction of the two second nozzles 12 adjacent to the left and right and the second nozzles 12 adjacent to the top and bottom are the same.

[0042] The utility model installs a filter cartridge 2 within a tank body 1, dividing the interior of the tank body 1 into an inner cavity for resin placement and an annular outer cavity for filtering foreign matter. An air / water inlet 1a is also provided at the bottom of the tank body 1, spraying air and water upward from the bottom to increase cleaning power, ensure the lifting and tumbling effect of the resin, increase the distribution of gaps between the resins, improve the dense resin packing state, increase the cleaning and filtration area, and improve cleaning efficiency. Water entering from the bottom drives the resin upward within the inner cavity of the filter cartridge 2, while the water flow simultaneously drives foreign matter out from the periphery and top of the filter cartridge 2, reducing foreign matter backflow and ensuring effective cleaning. The cleaning water can be recycled after filtration, reducing water consumption.

[0043] Figure 4 Schematic diagram of the pipe connection of the resin cleaning device of this embodiment. Figure 4 As shown, the resin cleaning device of this embodiment includes a resin washing tank 100, a circulating water storage tank 101, a clean air source (not shown), a clean water source (not shown), a water pump 102, a first filter 103, a second filter 104 and a gas-liquid mixing pump 105.

[0044] The outlet of the gas-liquid mixing pump 105 is connected to the air / water inlet 1a located at the bottom of the tank 1 via a first pipeline a. The inlet is connected to a clean air source and a clean water source via a second pipeline b and a third pipeline c, respectively. The inlet of the gas-liquid mixing pump 105 is also connected to the outlet of the water pump 102 via a fourth pipeline d. Each of the first pipeline a, the second pipeline b, the third pipeline c, and the fourth pipeline d is equipped with an electrically controlled valve k. This valve k serves as a pipeline control valve, controlling the on / off state of the pipeline. In this embodiment, the valve k is a pneumatic valve.

[0045] The second filter 104, acting as a post-pump filter, is installed on the fourth pipe d connected to the outlet of the water pump 102. The first filter 103, acting as a pre-pump filter, is installed on the fifth pipe e connected to the inlet of the water pump 102. The other end of the fifth pipe e is connected to the outlet of the circulating water storage tank 101. An electrically controlled valve k is installed on the fifth pipe e between the first filter 103 and the circulating water storage tank 101.

[0046] The air / water inlet 1a is also connected to the inlet of the circulating water storage tank 101 via a sixth pipeline f. The circulating water storage tank 101 is used to store wastewater from resin cleaning. After filtering, the wastewater can be recycled, reducing the number of water changes and water consumption. The sixth pipeline f is also equipped with an electrically controlled valve k.

[0047] The first drain port 7 is connected to the inlet of the circulating water storage tank 101 via the seventh pipe g. The second drain port 9 is connected to the inlet of the circulating water storage tank 101 via the eighth pipe h. The third drain port 10 is connected to the inlet of the circulating water storage tank 101 via the ninth pipe i. Wastewater discharged from the drain port and the gas / water inlet is collected in the circulating water storage tank 101. The seventh pipe g, the eighth pipe h, and the ninth pipe i are also provided with an electric control valve k for controlling the on / off of the pipes. When a nozzle is provided on the tank body, the nozzle is connected to the outlet of the gas-liquid mixing pump 105 via a pipe, so that water can be sprayed into the tank body 1.

[0048] The following combination Figures 1 to 4 , the working process of the resin cleaning device of this embodiment is described.

[0049] After the resin is added into the filter cartridge 2, during operation, the electric control valve k on the second pipeline b and the third pipeline c is opened, and the gas-liquid mixing pump 105 is started. Under the action of the gas-liquid mixing pump 105, clean water and air enter the tank body 1 through the air / water inlet 1a at the bottom of the tank body 1 and the first and second nozzles to flush the resin.

[0050] When the water level in the tank body 1 rises to cover the inner tank wall 6a of the overflow tank 6 and enters the overflow tank 6, the air control valve k on the seventh pipeline g is opened, and the water after cleaning the resin can enter the circulating water storage tank 101 through the first drain port 7.

[0051] When the water in the circulating water storage tank 101 reaches a certain amount, the air-controlled valve k on the fifth pipeline e is opened. The water in the circulating water storage tank 101 is filtered by the first filter 103 before entering the water pump 102. It is then filtered again by the second filter 104 to become clean water. The water then flows back to the tank body 1 through the gas-liquid mixing pump 105 via the fourth pipeline d to continue cleaning the resin in the tank body 1. During the recycling of the cleaning water, the air-controlled valve k on the third pipeline c can be closed to discontinue the continuous use of clean water, thereby reducing water consumption.

[0052] If the amount of resin to be cleaned is less than one tank, the resin can be cleaned as long as the water level in the tank body 1 is above the resin. At this time, the air-controlled valve k on the eighth pipeline h connected to the second drainage port 9 is opened, and the waste water after cleaning the resin can enter the circulating water storage tank 101 through the second drainage port 9 and the eighth pipeline h. When the water in the circulating water storage tank 101 accumulates to a certain amount, the air-controlled valve k on the fifth pipeline e is opened, and the water in the circulating water storage tank 101 is filtered by the first filter 103, enters the water pump 102, and then undergoes a second filtration through the second filter 104 to become clean water. The water then flows back to the tank body 1 through the fourth pipeline d and the gas-liquid mixing pump 105 to continue cleaning the resin in the tank body 1.

[0053] After the resin cleaning is completed, the waste water in the tank body 1 can be discharged through the first drain port 7 , the second drain port 9 , the third drain port 10 and the air / water inlet 1 a and flow into the circulating water storage tank 101 .

[0054] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
