Description

Technical Field

[0001] The invention relates to the field of cold storage technology, and in particular to a double-flow double-temperature section cold storage water tank body. Background Art

[0002] The water cold storage system includes a refrigeration main unit, a cold storage water tank, a circulating water pump, valves, a control unit, a production process heat exchange terminal, pipelines, etc., among which the cold storage water tank is the core equipment for cold storage. Water distributors are installed above and below the cold storage water tank. When storing cold, the refrigeration main unit takes low-temperature water and enters the lower water distributor through the pipeline. The lower water distributor evenly distributes the low-temperature water at the bottom of the tank. As the low-temperature water continues to enter the tank, the high-temperature water in the tank is pushed through the upper water distributor through the pipeline to flow out of the cold storage water tank to the refrigeration main unit for refrigeration until the low-temperature water fills the cold storage water tank and the cold storage is completed; when cooling, the high-temperature water generated at the heat exchange terminal of the production process enters the upper water distributor through the pipeline. The upper water distributor evenly distributes the high-temperature water at the top of the tank. As the high-temperature water continues to enter the tank, the low-temperature water in the tank is pushed through the lower water distributor through the pipeline to flow out of the cold storage water tank to the end of the production process to provide cooling until the high-temperature water fills the cold storage water tank and the cooling is completed. In the part of the tank where low-temperature water and high-temperature water come into contact, a water layer with a rapidly changing temperature will be produced. This is called the "thermocline layer", which can block the heat exchange between the low-temperature water and the high-temperature water, so the temperature of the low-temperature water and the high-temperature water above and below the thermocline layer can be kept stable.

[0003] In particular, establishing a water storage cooling system in the pharmaceutical production area can provide stable water temperature, emergency cold source and emergency water source for pharmaceutical process production, thereby improving pharmaceutical production efficiency and avoiding production accidents.

[0004] The publication number is CN113251527B, a water distributor and a water cold storage system, including a cylinder, characterized in that: a stirring blade and a flow blocking grid are installed in the cylinder, the cylinder is connected to the buffer disk, a disc-shaped buffer pad is arranged in the middle of the buffer disk, an annular flow limiting block is arranged inside the buffer disk and outside the buffer pad, a water flow channel is arranged in the flow limiting block, a hollow and annular flow divider is also arranged on the outside of the buffer disk, an annular flow equalizing pad is arranged inside the flow divider, and multiple groups of annular flow dividers are arranged on the outside of the flow divider along the thickness direction of the flow divider, and the flow dividers are arranged at intervals to form water outlets between the flow dividers. The above-mentioned water distributor can break up, stir, buffer, block, equalize and divert the water flow inside, and the water flow will become uniform and flow out slowly over a large area after passing through the water distributor, so that the outflowing water covers a larger area, is more evenly distributed, and has less disturbance to the water in the cold storage pipe, reduces the thickness of the inclined temperature layer, and significantly improves the water distribution effect.

[0005] Although the above technical solution can make the water flow coverage area larger and the distribution more uniform, in actual use, it is often necessary to adjust the flow rate of low-temperature water according to actual needs. When the demand for low-temperature water is large, it is necessary to further increase the water flow through the water distributor. The structure of the above-mentioned water distributor is relatively fixed, and the water flow through it cannot be adjusted to achieve the effect of further increasing the water flow. In addition, when the water distributor in the prior art is overhauled, it is necessary to remove the water distributor one by one for maintenance, and the maintenance steps are relatively cumbersome.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides a dual-flow dual-temperature section cold water storage tank body, which is established in a pharmaceutical production area and plays an important role in the pharmaceutical production process. First, the cold water storage tank can store low-temperature water or cold water at a lower temperature required for production. The circulating water pump is turned on to quickly transport the low-temperature water in the cold water storage tank to the end of the production process to provide cooling capacity, thereby quickly providing the cold temperature required for production, thereby improving pharmaceutical production efficiency and increasing production revenue; secondly, when the refrigeration main unit in the pharmaceutical production area fails or a short-term power outage fails to meet the cooling capacity required for pharmaceutical production, the cooling capacity stored in the cold water storage tank can be quickly provided to production as an emergency cooling source, ensuring the continuity and quality of production and avoiding production accidents; moreover, when there is a shortage of production water in the pharmaceutical production area, such as bursting and leakage of the water supply pipeline, the water stored in the cold water storage tank can be used as an emergency water source to supply production in time to ensure the normal progress of production.

[0037] like Figures 1 to 12 As shown, the dual-flow dual-temperature section cold water storage tank body includes a tank body 1, and also includes:

[0038] The upper water distributor 2 is fixedly arranged at the inner top of the tank body 1. The upper water distributor 2 can evenly distribute the high-temperature water at the top of the tank body 1. The upper water distributor 2 is a prior art and will not be described in detail here.

[0039] The mounting plate 3 is fixedly arranged inside the tank body 1 . A plurality of mounting holes 301 are formed through the mounting plate 3 . The lower water distributor 4 can be detachably mounted in the corresponding mounting holes 301 .

[0040] The lower water distributors 4 have the same number as the mounting holes 301 and are evenly arranged on the mounting plate 3 . The lower water distributors 4 can evenly distribute the low-temperature water at the bottom of the tank body 1 .

[0041] Specifically, the lower water distributor 4 includes a water-permeable seat 401, which is abutted against the top of the mounting plate 3, and the water-permeable seat 401 and the corresponding mounting hole 301 maintain a coaxial state; a water-permeable cover 402, which is fixedly arranged at the top of the water-permeable seat 401, and the water-permeable cover 402 is a truncated cone structure with a narrow top and a wide bottom and is elastic. When the water-permeable cover 402 is subjected to an expansion force from the inside to the outside, the water-permeable cover 402 will expand outward, and when the expansion force disappears, the water-permeable cover 402 will automatically return to its initial state; a water-permeable groove 403, there are multiple water-permeable grooves 403, which evenly penetrate the side of the water-permeable cover 402. The gap size of the water-permeable grooves 403 can change with the deformation of the water-permeable cover 402. When the water-permeable cover 402 is expanded outward by the expansion force, the gap size of the water-permeable grooves 403 will also increase synchronously; the water-permeable holes 404 are coaxially penetrated and opened in the middle of the water-permeable seat 401. The water flow above the lower water distributor 4 enters the interior of the water-permeable cover 402 through the multiple water-permeable grooves 403, and then flows to the bottom of the tank body 1 through the water-permeable holes 404.

[0042] There are multiple flow-increasing components 5 , which are respectively arranged inside the corresponding lower water distributors 4 .

[0043] Specifically, the flow-increasing component 5 includes an expansion support ring 501, which is arranged inside the water-permeable cover 402; a plurality of flow-increasing holes 502, which are uniformly penetrated through the water-permeable seat 401, and the plurality of flow-increasing holes 502 are uniformly located on the periphery of the water-permeable hole 404; a flow-blocking ring 503, which is rotatably arranged inside the water-permeable seat 401 and is located below the plurality of flow-increasing holes 502; and through holes 504, which are the same in number as the flow-increasing holes 502 and are uniformly penetrated through the flow-blocking ring 503. By controlling the rotation of the flow-blocking ring 503, the through holes 504 can correspond to or stagger with the flow-increasing holes 502, thereby achieving the purpose of controlling the on-off of the flow-increasing holes 502. The connecting plate 505 is fixedly arranged at the bottom end of the flow-blocking ring 503; the upper wedge block 506 is fixedly arranged at the bottom end of the connecting plate 505; the lower wedge block 507 is fixedly arranged at the top of the supporting frame 601 and is located below the upper wedge block 506. When the lower wedge block 507 moves upward, it can resist the upper wedge block 506. Under the cooperation of the two inclined surfaces of the upper wedge block 506 and the lower wedge block 507 contacting each other, the upper wedge block 506 drives the connecting plate 505 and the flow-blocking ring 503 to rotate, thereby controlling the on and off of the flow-increasing hole 502; the dial plate 508, one end of which is connected to the The elastic member 509 is fixedly arranged on the inner side of the water permeable hole 404; the top rod 510, one end of which is fixedly arranged on the inner side of the water permeable seat 401 through the elastic member 509, and the other end is against the bottom end of the dial plate 508; the inclined groove 511 is penetrated and opened on the side of the connecting plate 505, and the top rod 510 is slidably arranged inside the inclined groove 511, the elastic member 509 is elastic, and can only bend in the vertical direction, and will not bend in the horizontal direction. The dial plate 508 and the corresponding top rod 510 always move in the same vertical plane. When the lower wedge block 507 moves upward to rotate the connecting plate 505, The push rod 510 is forced to slide along the inclined groove 511, so that one end of the push rod 510 rotates around the corresponding elastic member 509, the corresponding elastic member 509 bends in the vertical direction, and the other end of the push rod 510 pushes the paddle 508 upward, so that one end of the paddle 508 rotates around the corresponding elastic member 509, the corresponding elastic member 509 bends in the vertical direction, and the other end of the paddle 508 moves upward under the push of the push rod 510; the support frame 512 is fixedly arranged in the middle of the water permeable hole 404; the limit sleeve 513 is fixedly arranged in the middle of the support frame 512;The extension rod 514 is slidably arranged inside the limiting sleeve 513, and the expansion support ring 501 is fixedly arranged on the top of the extension rod 514 through the fixing rod 515. The inner wall of the limiting sleeve 513 is fixedly provided with a limiting block, and the outer wall of the extension rod 514 is provided with a limiting groove. The limiting block is slidably arranged in the limiting groove. Through the mutual cooperation between the limiting block and the limiting groove, the extension rod 514 can only slide up and down in the limiting sleeve 513, and no relative rotation occurs between the two. Similarly, the limiting block can also be fixedly arranged on the outer wall of the extension rod 514, and the limiting groove is provided on the inner wall of the limiting sleeve 513. The cooperation between the limiting groove and the limiting block is a prior art. The connection seat 516 is fixedly arranged at the bottom end of the extension rod 514; the clamping groove 517 is provided on the side of the connection seat 516, and the other end of the dial plate 508 is located inside the clamping groove 517. When the dial plate 508 rotates, the end located in the clamping groove 517 drives the connection seat 516 to move upward through the clamping action with the clamping groove 517; the water-permeable seat 401 is provided with a rotating groove 518, and the flow blocking ring 503 is sealed and rotated in the rotating groove 518. When the through hole 504 and the flow-increasing hole 502 are completely staggered, the flow-increasing hole 502 is completely blocked by the flow blocking ring 503. ;

[0044] It should be noted that the size of the slot 517 is sufficient to accommodate the movement of one end of the shift plate 508 therein. When the shift plate 508 drives the connecting seat 516 to move through the slot 517, the edge of the slot 517 always remains in contact with the top of the shift plate 508, and the slot 517 will not interfere with the movement of the shift plate 508.

[0045] The top-stop assembly 6 is arranged inside the tank body 1 and can adjust the state of the flow-increasing assembly 5 .

[0046] Specifically, the push-up assembly 6 includes a push-up frame 601, which is slidably arranged inside the tank body 1 and is located below the mounting plate 3; a telescopic rod 602, whose movable end is fixedly arranged at the bottom end of the push-up frame 601, and the telescopic rod 602 can be pneumatic or hydraulic, and its state can be adjusted by an external control system; a support plate 603, which is fixedly arranged on the inner wall of the tank body 1, and the fixed end of the telescopic rod 602 is fixedly arranged at the top of the support plate 603. By controlling the extension and retraction of the telescopic rod 602, the push-up frame 601 can slide up and down inside the tank body 1, thereby realizing the adjustment of the position of the push-up frame 601.

[0047] The snap-on assembly 7 can facilitate the installation of the lower water distributor 4 on the mounting plate 3 .

[0048] Specifically, the clamping assembly 7 includes an L-shaped claw 701, which is fixedly arranged at the bottom end of the water-permeable seat 401. The L-shaped claw 701 passes through the mounting hole 301 and is clamped at the bottom end of the mounting plate 3. The vertical section of the L-shaped claw 701 is elastic and can be deformed under the action of the extrusion force; a spherical protrusion 702, which is fixedly arranged at the top of one side of the corresponding L-shaped claw 701; a spherical groove 703, which is opened at the bottom end of the mounting plate 3. When the lower water distributor 4 is installed, multiple L-shaped claws 701 are squeezed inwardly so that the vertical sections of multiple L-shaped claws 701 are moved toward the center. 301, and then insert multiple L-shaped claws 701 into the mounting hole 301 until the horizontal section of the L-shaped claw 701 moves downward to the bottom of the mounting plate 3, and the L-shaped claw 701 is no longer subjected to the extrusion force and automatically returns to a vertical state. At this time, the vertical section of the L-shaped claw 701 is clamped on the inner side of the mounting hole 301, and the horizontal section is clamped on the bottom of the mounting plate 3. Moreover, after installation in place, the spherical protrusion 702 is clamped in the spherical groove 703, which can effectively prevent the lower water distributor 4 from rotating on the mounting plate 3. At this point, the installation and fixation of the lower water distributor 4 is completed.

[0049] The water inlet end 8 is fixedly arranged at the top end of the tank body 1, and the bottom end is connected with the upper water distributor 2, and is used for supplying high-temperature water in and out.

[0050] The water outlet 9 is connected to the bottom of the tank 1 and is used for supplying low-temperature water.

[0051] When in use, high-temperature water enters the upper water distributor 2 through the water inlet end 8, and the upper water distributor 2 evenly distributes the high-temperature water in the tank body 1. With the continuous injection of high-temperature water, the low-temperature water inside the tank body 1 will be pushed through the lower water distributor 4 and out through the water outlet end 9 to provide cooling.

[0052] Specifically, in the initial state, the telescopic rod 602 is in a retracted state, the lower wedge block 507 does not push against the upper wedge block 506, the flow-blocking ring 503 does not rotate in the rotating groove 518, the through hole 504 and the flow-increasing hole 502 are completely staggered, the flow-increasing hole 502 is completely blocked by the flow-blocking ring 503, and the lower water distributor 4 distributes the low-temperature water in the tank body 1 in a normal state. The low-temperature water in the tank body 1 flows to the bottom of the tank body 1 through the water-permeable groove 403 and the water-permeable hole 404 in sequence at a normal flow rate; when the demand for low-temperature water is large, it is necessary to further increase the flow rate of low-temperature water passing through the lower water distributor 4, and at this time, the control The telescopic rod 602 is controlled to extend, and the telescopic rod 602 drives the support frame 601 to move upward. In this process, the support frame 601 drives the lower wedge block 507 upward to resist the corresponding upper wedge block 506. Through the cooperation of the two inclined surfaces contacting each other between the upper wedge block 506 and the lower wedge block 507, the upper wedge block 506 drives the connecting plate 505 to rotate, and the connecting plate 505 drives the flow blocking ring 503 to rotate in the rotating groove 518, so that the through hole 504 and the flow increasing hole 502 correspond to each other, thereby increasing the flow rate of the low-temperature water in the water permeable cover 402 to the bottom of the tank body 1. The staff can adjust the telescopic rod 602 to extend, and the telescopic rod 602 drives the support frame 601 to move upward. The elongated length of the retracted rod 602 controls the height of the lower wedge block 507, thereby controlling the rotation angle of the upper wedge block 506, thereby adjusting the flow blocking ring 503 to different rotation angles, and then adjusting the connection area between the through hole 504 and the flow increasing hole 502; at the same time, when the connecting plate 505 rotates, the top rod 510 drives the dial plate 508 to rotate under the action of the inclined groove 511, and the dial plate 508 drives the connecting seat 516 to move upward through the card slot 517, so that the connecting seat 516 drives the expansion ring 501 to move upward through the extension rod 514 and the fixing rod 515. When the expansion ring 501 moves upward, the water-permeable cover 402 will be expanded from the inside to the outside. The water-permeable cover 402 will be deformed outward under the expansion effect of the expansion ring 501, thereby causing the multiple water-permeable grooves 403 to be deformed, and the gap size of the water-permeable grooves 403 will increase. At this time, the water flow rate entering the water-permeable cover 402 through the water-permeable grooves 403 will also increase synchronously; in summary, when the support frame 601 moves upward, the area of ​​the through hole 504 and the flow-increasing hole 502 that is interconnected will increase accordingly, and the water-permeable cover 402 will be expanded from the inside to the outside, so that the gap size of the multiple water-permeable grooves 403 will increase synchronously.

[0053] It should be noted that the staff can adjust the length of the telescopic rod 602 according to actual needs, so as to effectively adjust the connection area between the through hole 504 and the flow-increasing hole 502 and the gap size of the water-permeable groove 403, and the change between the above connection area and the gap size is proportional.

[0054] Through the coordinated use of the water-permeable cover 402, the water-permeable groove 403, the flow-increasing component 5 and the abutting component 6, the abutting component 6 abuts the flow-increasing component 5, so that the connecting area between the through hole 504 and the flow-increasing hole 502 is gradually increased, thereby increasing the water flow from the water-permeable cover 402 through the water-permeable seat 401 into the bottom of the tank body 1. At the same time, the gap sizes of the multiple water-permeable grooves 403 are synchronously increased, thereby increasing the water flow from the tank body 1 through the water-permeable grooves 403 into the water-permeable cover 402. By simultaneously increasing the water flow through the water-permeable grooves 403 and the water flow through the water-permeable seat 401, the purpose of further increasing the water flow through the lower water distributor 4 is achieved, thereby solving the problem that the traditional water distributor cannot further increase the water flow, achieving the effect of being able to quickly provide low-temperature water and saving the time required for refrigeration.

[0055] The water-permeable cover 402 is expanded outward by the expansion ring 501, so that the gap size between the multiple water-permeable grooves 403 is increased. When the staff inspects the lower water distributor 4, there is no need to disassemble the lower water distributor 4 one by one for inspection. The internal situation of the lower water distributor 4 can be observed through the enlarged gap, and it can be intuitively understood whether there are impurities and blockages in the water-permeable cover 402.
