Description

Technical Field

[0001] This invention relates to the field of concentrated wastewater recovery technology, and more particularly to a recovery tank suitable for concentrated wastewater recovery. Background Technology

[0002] Reverse osmosis technology is a general technology for solving "water problems" and has the advantages of clean production, such as saving land and not producing other pollution. The application of reverse osmosis membrane technology in water treatment of power plants in my country has received widespread attention due to its wide range of applicable water quality, high efficiency and environmental protection.

[0003] As reverse osmosis systems have become more sophisticated, the quality of the secondary reverse osmosis concentrate has begun to meet environmental standards for process water. This has led to a situation where high water usage is underutilized, resulting in a serious waste of water resources. Traditionally, the concentrate is discharged directly into the ocean, which greatly wastes usable water resources and increases water costs. Therefore, a recycling pond can be used to recycle the concentrate. However, traditional recycling ponds have few connection points. When adding reverse osmosis filtration points, it is often necessary to open new connection points. Re-installing traditional ponds requires completely draining the concentrate from the recycling pond, which affects the concentrate recycling process. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the aforementioned problem that adding pipeline connections during concentrated water recovery is quite troublesome, this invention is proposed.

[0006] Therefore, the object of this invention is to provide a recovery tank suitable for concentrated wastewater recovery.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a recovery tank suitable for concentrated water recovery, comprising: a recovery unit, including a recovery tank, an interface component disposed on the recovery tank, a transport pipe disposed on the interface component, and an inflow hole disposed on the recovery tank; and an automatic opening and closing unit, including a covering component disposed on the recovery tank, a triggering component disposed on the recovery tank, and a sealing component disposed on the recovery tank.

[0008] As a preferred embodiment of the recovery tank suitable for concentrate recovery according to the present invention, the interface includes a connecting pipe disposed on the recovery tank and a flange disposed on the connecting pipe.

[0009] As a preferred embodiment of the recovery tank suitable for concentrate recovery according to the present invention, the covering assembly includes a support rod disposed on the recovery tank, a cover plate disposed on the support rod, and a rubber ring disposed on the cover plate, wherein the rubber ring is located on the side of the inlet hole.

[0010] As a preferred embodiment of the recovery tank applicable to concentrate recovery according to the present invention, the triggering component includes a transmission component disposed on the recovery tank, a triggering component disposed on the transmission component, a snap-fit ​​component disposed on the triggering component, and a pulling component disposed on the triggering component.

[0011] As a preferred embodiment of the recovery tank suitable for concentrated water recovery according to the present invention, the transmission component includes an arc-shaped groove disposed on the recovery tank, a slider disposed on the arc-shaped groove, and a connecting rod disposed on the slider.

[0012] As a preferred embodiment of the recovery tank suitable for concentrated water recovery according to the present invention, the triggering element includes an arc-shaped block disposed on a connecting rod, a fixed spring disposed on the arc-shaped block, a connecting plate disposed on the fixed spring, and a contact rod disposed on the connecting plate.

[0013] As a preferred embodiment of the recycling tank applicable to concentrate recycling according to the present invention, the fastener includes a fixing block disposed on the arc-shaped block, a retaining spring disposed on the fixing block, a bonding plate disposed on the arc-shaped block and connected to the retaining spring, a fastener block disposed on the bonding plate, and a slot disposed on the arc-shaped groove.

[0014] As a preferred embodiment of the recycling tank suitable for concentrated water recycling according to the present invention, the pulling member includes an extension plate disposed on the connecting plate, a pulling belt disposed on the extension plate and connected to the bonding plate, and a support rod disposed on the extension plate.

[0016] As a preferred embodiment of the recovery tank for concentrated water recovery according to the present invention, the bulging component includes a receiving groove disposed on the inlet, an air bladder disposed on the receiving groove, and an air pipe disposed on the air bladder and communicating with the cavity.

[0017] The beneficial effects of this invention are as follows: By setting up multiple sets of automatic opening and closing units, this invention does not affect the normal operation of the recovery tank when these automatic opening and closing units are not in use. When adding recovery pipes to the recovery tank, the automatic opening and closing units ensure that the process of adding pipes and connecting them to the recovery tank does not affect the operation of other channels, thus improving the recovery efficiency of concentrated water. Furthermore, when connecting the transport pipe to the recovery tank, the transport pipe can be directly connected to the connecting pipe of the recovery tank. When the connection is completed, the inlet automatically opens, and when the transport pipe is disconnected from the recovery tank, the inlet automatically closes. This eliminates the need to rotate valves to open and close the connecting pipes as in traditional pipes, greatly improving the convenience of pipe connection and disassembly.

[0031] Example 1

[0032] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a recycling tank 101 suitable for the recycling of concentrated water, including a recycling unit 100 and an automatic opening and closing unit 200. The recycling unit 100 is used to connect to the discharge end of the concentrated water so that the concentrated water can be recycled after treatment. The recycling unit 100 is provided with multiple sets of automatic opening and closing units 200. When not in use, its automatic opening and closing units 200 are in a locked state, while when in use, the pipe can be automatically opened.

[0033] Specifically, the recycling unit 100 includes a recycling tank 101 for storing the treated concentrate, an interface 102 installed on the recycling tank 101 for fixed connection with a transport pipe 103, a transport pipe 103 installed on the interface 102 for transporting the treated concentrate to the recycling tank 101, and an inflow hole 104 opened on the recycling tank 101, extending from the interface side into the interior of the recycling tank 101.

[0034] Furthermore, the interface component 102 includes a connecting pipe 102a disposed on the recycling pool 101 and a flange 102b installed on the connecting pipe 102a. The flange 102b is used to fix and lock the connecting pipe 102a and the transport pipe 103, so that the connection between the connecting pipe 102a and the transport pipe 103 is stable.

[0035] Operation process: During the recovery of concentrated water, the concentrated water flows from the discharge end into the transport pipe 103, and then from the transport pipe 103 to the connecting pipe 102a, so that the treated concentrated water flows from the inlet hole 104 into the recovery tank 101, thereby enabling the recovery tank 101 to recover the concentrated water.

[0036] Example 2

[0037] Reference Figures 2-8 This is the second embodiment of the present invention, which differs from the first embodiment in that: the automatic opening and closing unit 200 includes a cover component 201 disposed on the recycling pool 101, the cover component 201 being located on one side of the inflow hole 104 on the inner wall of the recycling pool 101, a trigger component 202 installed on the recycling pool 101, and the trigger component 202 extending from inside the recycling pool 101 to one end of the connecting pipe 102a, and a sealing component 203 installed on the recycling pool 101, the sealing component 203 being used to seal between the cover component 201 and the inflow hole 104. When the transport pipe 103 is connected to the connecting pipe 102a, the port of the transport pipe 103 preferentially contacts the trigger component 202, the trigger component 202 is pressed, thereby canceling the locking of the cover component 201. At this time, the cover component 201 is no longer closed on the inflow hole 104, and the transport pipe 103 is in a connected state with the recycling pool 101.

[0038] Specifically, the covering assembly 201 includes a support rod 201a disposed on the recycling pool 101. The support rod 201a is telescopic. A cover plate 201b is installed at one end of the support rod 201a. A rubber ring 201c is installed on the outer wall of the cover plate 201b, and the rubber ring 201c is located on one side of the inflow hole 104. The diameter of the rubber ring 201c is the same as the diameter of the inflow hole 104. When the support rod 201a is fully retracted, the cover plate 201b is attached to the inner wall of the recycling pool 101. At this time, the rubber ring 201c is completely embedded in the inflow hole 104.

[0039] Furthermore, the triggering component 202 includes a transmission component 202a disposed on the recycling pool 101 and a triggering component 202b mounted on the transmission component 202a. When the transport pipe 103 is connected to the connecting pipe 102a, the transport pipe 103 presses against the triggering component 202b. The triggering component 202b drives the pulling component 202d mounted on the triggering component 202b. The pulling component 202d drives the locking component 202c mounted on the triggering component 202b to move, so that the locking component 202c is no longer locked on the arc groove 202a-1. At this time, the triggering component 202b can drive the transmission component 202a to move. The movement of the transmission component 202a drives the cover plate 201b to move, thereby opening the inflow hole 104.

[0040] Furthermore, the transmission component 202a includes two sets of arc-shaped grooves 202a-1 formed on the recycling pool 101. A slider 202a-2 is installed on the inner wall of the arc-shaped groove 202a-1, and a connecting rod 202a-3 is installed on the outer wall of the slider 202a-2. The slider 202a-2 supports the connecting rod 202a-3, and the connecting rod 202a-3 is connected to the cover plate 201b, so that the movement of the cover plate 201b is synchronized with the movement of the connecting rod 202a-3.

[0041] Furthermore, the trigger 202b includes an arc-shaped block 202b-1 disposed on the connecting rod 202a-3. The arc-shaped block 202b-1 fits into the arc-shaped groove 202a-1. A set of fixing springs 202b-2 is installed on the inner wall of the arc-shaped block 202b-1. A connecting plate 202b-3 is installed on one end of the fixing spring 202b-2. A contact rod 202b-4 is installed on the connecting plate 202b-3, and the contact plate extends out of one end of the connecting pipe 102a. When the transport pipe 103 is connected to the connecting pipe 102a, the transport pipe 103 presses the contact rod 202b-4 to connect, and the contact rod 202b-4 drives the connecting plate 202b-3 to move.

[0042] Furthermore, the fastener 202c includes a fixing block 202c-1 installed on the inner wall of the arc-shaped block 202b-1, two sets of retaining springs 202c-2 installed on the fixing block 202c-1, and an adhesive plate 202c-3 installed on the arc-shaped block 202b-1 and connected to the retaining springs 202c-2. The retaining springs 202c-2 apply a downward elastic force, causing the fastener block 202c-4 installed on the bottom side of the adhesive plate 202c-3 to embed into the slot 202c-5 opened in the arc-shaped groove 202a-1. This causes the arc-shaped block 202b-1 to be locked on one side of the slot 202c-5, making the connecting rod 202a-3 connected to the arc-shaped block 202b-1 immovable, thus locking the cover plate 201b. This locks the cover plate 201b tightly against one end of the inlet hole 104. When the transport pipe 103 separates from the connecting pipe 102a, its cover plate 201b is quickly pulled towards the inlet 104, thus sealing the inlet hole 104 and ensuring timely locking of the inlet hole 104.

[0043] Furthermore, the pulling component 202d includes an extension plate 202d-1 mounted on the connecting plate 202b-3, a pulling belt 202d-2 mounted on the extension plate 202d-1 and connected to the bonding plate 202c-3, a support rod 202d-3 mounted on the outer wall of the extension plate 202d-1, and the other end of the support rod 202d-3 mounted on the inner wall of the arc-shaped block 202b-1. When the contact rod 202b-4 moves, the contact rod 202b-4 drives the extension plate 202d-1 to move, the movement of the extension plate 202d-1 drives the pulling belt 202d-2 to move, the movement of the pulling belt 202d-2 pulls the bonding plate 202c-3 to move, and the movement of the bonding plate 202c-3 drives the buckle block 202c-4 to move. When the contact rod 202b-4 is completely pressed into the connecting tube 10... Within 2a, the transport pipe 103 is connected to the connecting pipe 102a, and the buckle block 202c-4 is completely disengaged from the slot 202c-5. At this time, the spring presses the arc-shaped block 202b-1, causing the arc-shaped block 202b-1 to drive the connecting rod 202a-3 to connect with the slider 202a-2, thereby opening the inflow hole 104 of the cover plate 201b. At this time, the transport pipe 103 is connected to the inside of the recycling pool 101, and the transport pipe 103 is installed. At the same time as the transport pipe 103 is installed, its inflow hole 104 is also opened. When connecting the transport pipe 103, only the splicing of the pipe needs to be considered, and the opening of the channel between the recycling pool 101 and the transport pipe 103 does not need to be considered, making the connection between the transport pipe 103 and the recycling pool 101 quick and convenient.

[0044] The rest of the structure is the same as in Example 1.

[0045] Operation process: The spring 202c-2 maintains a downward elastic force, causing the latching block 202c-4 mounted on the bottom side of the bonding plate 202c-3 to engage with the slot 202c-5 formed in the arc-shaped groove 202a-1. This locks the arc-shaped block 202b-1 into one side of the slot 202c-5, making the connecting rod 202a-3 connected to the arc-shaped block 202b-1 immovable. Consequently, the cover plate 201b is locked and thus locked against one end of the inflow hole 104. When the transport pipe 103 is connected to the connecting pipe 102a, the transport pipe 103 presses against the contact rod 202b-4. The contact rod 202b-4 drives the connecting plate 202b-3 to move. The movement of the connecting plate 202b-3 drives the extension plate 202d-1 to move. The movement of the extension plate 202d-1 drives the pulling belt 202d-2 to move. The movement of the pulling belt 202d-2 pulls the bonding plate 202c-3 to move. The movement of the bonding plate 202c-3 drives the buckle block 202c-4 to move. When the contact rod 202b-4 is completely pressed against the connecting pipe 102a, the connecting pipe 103 presses against the connecting rod 202b-4 to move. When the conveying pipe 103 is pressed into the connecting pipe 102a, the connection between the conveying pipe 103 and the connecting pipe 102a is completed. At this time, the latching block 202c-4 is completely disengaged from the slot 202c-5. Then, the spring-loaded arc-shaped block 202b-1 is installed, causing the arc-shaped block 202b-1 to drive the connecting rod 202a-3 to connect with the slider 202a-2, thereby causing the cover plate 201b to open the inflow hole 104. This structure ensures that when adding a recycling pipeline, the connection between one conveying pipe 103 and the recycling pool 101 does not affect the other recycling channels. This significantly improves the efficiency of concentrated water recovery. When connecting the transport pipe 103, only the pipe splicing needs to be considered, without needing to consider opening the channel between the recovery tank 101 and the transport pipe 103. This is because the pipe is automatically connected to the recovery tank 101 when the pipe splicing is completed, and the flow hole 104 is automatically locked when the transport pipe 103 is disconnected from the recovery tank 101. Unlike the traditional method, it is no longer necessary to rotate the valve to open or close the channel, which effectively improves the convenience of connecting and disassembling the recovery tank 101 and the connecting pipe 102a.

[0046] Example 3

[0047] Reference Figure 2 and Figure 6 This is the third embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the sealing assembly 203 includes two sets of cavities 203a installed on the recycling pool 101. A circular piston 203b is installed on the inner wall of each set of cavities 203a. A connecting shaft 203c connected to the cover plate 201b is installed on the outer wall of the circular piston 203b. A bulge 203d is installed on the inner wall of the inflow hole 104. When the cover plate 201b is in contact with the inner wall of the recycling pool 101, the connecting shaft 203c drives the circular piston 203b to move. The movement of the circular piston 203b causes the gas in the cavity 203a to be injected into the bulge 203d, so that the bulge 203d is pressed and adhered to the rubber ring 201c.

[0048] Specifically, the bulging component 203d includes a receiving groove 203d-1 formed on the inlet hole 104. An airbag 203d-2 is installed on the inner wall of the receiving groove 203d-1, and an air pipe 203d-3 communicating with the cavity 203a is installed on the outer wall of the airbag 203d-2. The gas in the cavity 203a enters the airbag 203d-2 through the air pipe 203d-3. The airbag 203d-2 bulges and contacts the embedded rubber ring 201c, thereby sealing and locking the inlet hole 104. When the cover plate 201b moves back, the gas in the airbag 203d-2 is drawn back into the cavity 203a, so that the airbag 203d-2 is completely contracted into the receiving groove 203d-1, thus not affecting the flow of concentrated water.

[0049] The rest of the structure is the same as in Example 2.

[0050] Operation process: When the cover plate 201b is in contact with the inner wall of the recovery tank 101, the connecting shaft 203c drives the circular piston 203b to move. The movement of the circular piston 203b causes the gas in the cavity 203a to enter the airbag 203d-2 through the air pipe 203d-3. The airbag 203d-2 inflates and contacts the embedded rubber ring 201c, thereby sealing and locking the inlet hole 104. When the cover plate 201b moves back, the gas in its airbag 203d-2 is drawn back into the cavity 203a, so that the airbag 203d-2 is completely contracted into the interior of the receiving tank 203d-1, thus not affecting the flow of concentrated water.
