Under the condition that the water storage capacity is kept the same, the single capacity and size of the first water storage tank and the second water storage tank can be made smaller, so that even if the space height design of water making rooms of some pharmaceutical enterprises is small due to the early-stage planning problem, the first water storage tank and the second water storage tank can be normally matched and installed.

Description

Technical Field

[0001] This application relates to the technical field of liquid transportation, and particularly to a multi-tank single-way distribution system. Background Art

[0002] In the daily production activities of pharmaceutical enterprises, the work of supplying purified water or injection water to production workshops or laboratories is involved. Currently, the water supply systems for purified water or injection water usually consist of vertical or horizontal water storage tanks connected to a set of circulation pipelines. And to meet the large water demand, the capacity and size of the water storage tanks are generally designed to be relatively large.

[0003] However, for some pharmaceutical factories, due to problems such as pre-design planning, the space height design of some water treatment rooms is very limited, resulting in the inability to install water storage tanks with large capacity and size in these water treatment rooms. And once the components on the water storage tank are damaged, the water storage tank will be completely unusable, causing the water supply to be interrupted and unable to meet the water demand. Summary of the Invention

[0004] Based on this, in view of the problems in the prior art that the installation applicable scenarios are limited and cannot meet the water demand, it is necessary to provide a multi-tank single-way distribution system.

[0005] This application provides a multi-tank single-way distribution system, which includes:

[0006] A water storage container, the water storage container includes a first water storage tank and a second water storage tank connected in parallel;

[0007] A water delivery pipeline, the water inlet end of the water delivery pipeline is communicated with the water storage container;

[0008] A water usage site, the water usage site is communicated with the water outlet end of the water delivery pipeline;

[0009] A driving water pump, the driving water pump is arranged in the water delivery pipeline; and,

[0010] A return water pipeline, the water inlet end of the return water pipeline is communicated with the water usage site, and the water outlet end of the return water pipeline is communicated with the water storage container.

[0011] In the multi-tank single-path distribution system of this solution, compared with the prior art which usually uses a single large-capacity and large-size water storage tank, the water storage container in this application is specifically composed of a first water storage tank and a second water storage tank connected in parallel. It is easy to understand that when the water storage capacity remains the same, the single capacity and size of the first water storage tank and the second water storage tank can be made smaller. In this way, even if the space height of the water production room in some pharmaceutical enterprises is designed to be relatively small due to pre-planning problems, the first water storage tank and the second water storage tank can still be properly installed and adapted. During operation, one or both of the first water storage tank and the second water storage tank output purified water or injection water to the water supply pipeline. Under the driving force provided by the driving water pump, the purified water or injection water flows along the water supply pipeline into the water-using place to meet the water demand, and the excess water can return to the first water storage tank and / or the second water storage tank through the water return pipeline; in addition, when the components in the first water storage tank are damaged and cannot be used normally, the second water storage tank plays a backup role at this time, and the second water storage tank can still ensure the continuous normal operation of the multi-tank single-path distribution system when supplying water alone (of course, when the second water storage tank is damaged, the first water storage tank can also ensure the normal operation of the system), thereby avoiding water supply interruption and resulting in the inability to meet the water demand.

[0012] The technical solution of this application will be further described below:

A lot of specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0029] In addition, if terms such as "first" and "second" appear, these terms are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0030] In the present application, unless otherwise clearly specified and limited, if terms such as "install", "connect", "couple", "fix", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] In this application, unless otherwise clearly specified and defined, when a first feature is described as "on" or "under" a second feature or similar descriptions, it may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0032] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0033] Refer to Figure 1 , a multi-tank single-way distribution system 100 shown in an embodiment of this application, which includes a water storage container 10, a water supply pipeline 20, a water usage site 30, a driving water pump 40 and a return water pipeline 50.

[0034] The water storage container 10 includes a first water storage tank 11 and a second water storage tank 12 connected in parallel. It can be understood that the water inlet ends of the first water storage tank 11 and the second water storage tank 12 are both connected with a water inlet pipe, and the water outlet ends are both connected with a water outlet pipe; one end of the two water inlet pipes far away from the first water storage tank 11 and the second water storage tank 12 is connected to the return water pipeline 50, and one end of the two water outlet pipes far away from the first water storage tank 11 and the second water storage tank 12 is connected to the water supply pipeline 20, thereby realizing that the first water storage tank 11 and the second water storage tank 12 form a parallel structure.

[0035] To reduce the design and manufacturing costs, the first water storage tank 11 and the second water storage tank 12 preferably adopt the same structural design, for example, both are cylindrical structures. To improve the service life, the first water storage tank 11 and the second water storage tank 12 are integrally formed by welding stainless steel plates.

[0036] The water inlet end of the water supply pipeline 20 is communicated with the water storage container 10; the water usage site 30 is communicated with the water outlet end of the water supply pipeline 20; the driving water pump 40 is disposed in the water supply pipeline 20; the water inlet end of the return water pipeline 50 is communicated with the water usage site 30, and the water outlet end of the return water pipeline 50 is communicated with the water storage container 10.

[0037] Optionally, the driving water pump 40 can be any one of a multi-stage pump, a centrifugal pump, etc., and can be specifically selected according to actual needs.

[0038] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: In the multi-tank single-path distribution system 100 of this solution, compared with the prior art that usually uses a single large-capacity and large-size water storage tank, the water storage container 10 in this application is specifically composed of a first water storage tank 11 and a second water storage tank 12 connected in parallel. It is easy to understand that when the water storage capacity remains the same, the single capacity and size of the first water storage tank 11 and the second water storage tank 12 can be made smaller. In this way, even if the height of the water production room of some pharmaceutical enterprises is designed to be small due to pre-planning problems, the first water storage tank 11 and the second water storage tank 12 can still be properly adapted and installed. During operation, one or both of the first water storage tank 11 and the second water storage tank 12 output purified water or injection water to the water delivery pipeline 20. Under the action of the power provided by the driving water pump 40, the purified water or injection water flows along the water delivery pipeline 20 into the water usage site 30 to meet the water usage requirements, and the excess water can return to the first water storage tank 11 and / or the second water storage tank 12 through the water return pipeline 50; in addition, when the components in the first water storage tank 11 are damaged and cannot be used normally, the second water storage tank 12 plays a backup role at this time, and the second water storage tank 12 can still ensure the continuous normal operation of the multi-tank single-path distribution system 100 when supplying water alone (of course, when the second water storage tank 12 is damaged, the first water storage tank 11 can also ensure the normal operation of the system), thereby avoiding water supply interruption and resulting in the inability to meet the water usage requirements.

[0039] In addition, on the basis of the above embodiment, the multi-tank single-path distribution system 100 further includes a first control valve group and a second control valve group. The first control valve group is connected to the first water storage tank 11 through a pipeline, and the first control valve group is connected to the water delivery pipeline 20 and the water return pipeline 50; the second control valve group is connected to the second water storage tank 12 through a pipeline, and the second control valve group is connected to the water delivery pipeline 20 and the water return pipeline 50.

[0040] In actual use, if the components in the first water storage tank 11 are damaged and cannot be used normally, the water path of the first water storage tank 11 can be cut off by operating the first control valve group, and only the second water storage tank 12 can have a normal water path connection. The system can still ensure normal water supply through the second water storage tank 12. The function of the second control valve group is the same as that of the first control valve group and will not be elaborated here.

[0041] Please continue to refer to Figure 1, specifically, in the above embodiments, the first control valve group includes a first water inlet control valve 60 and a first drain control valve 60a. The first water inlet control valve 60 is connected between the water inlet end of the first water storage tank 11 and the return water pipeline 50, and the first drain control valve 60a is connected between the water outlet end of the first water storage tank 11 and the water delivery pipeline 20. When the first water storage tank 11 is damaged, the first water inlet control valve 60 and the first drain control valve 60a are simultaneously closed, and the water inlet and drain paths of the first water storage tank 11 can be shut off, thereby facilitating the maintenance and repair of the first water storage tank 11.

[0042] Similarly, the second control valve group includes a second water inlet control valve 60b and a second drain control valve 60c. The second water inlet control valve 60b is connected between the water inlet end of the second water storage tank 12 and the return water pipeline 50, and the second drain control valve 60c is connected between the water outlet end of the second water storage tank 12 and the water delivery pipeline 20. When the second water storage tank 12 is damaged, the second water inlet control valve 60b and the second drain control valve 60c are simultaneously closed, and the water inlet and drain paths of the second water storage tank 12 can be shut off, thereby facilitating the maintenance and repair of the second water storage tank 12.

[0043] In addition, on the basis of any of the above embodiments, the multi-tank single-path distribution system 100 further includes a first temperature transmitter 70, and the first temperature transmitter 70 is disposed on the first water storage tank 11. Further, the multi-tank single-path distribution system 100 further includes a second temperature transmitter 70a, and the second temperature transmitter 70a is disposed on the second water storage tank 12. The first temperature transmitter 70 and the second temperature transmitter 70a are used to respectively and real-time detect the temperature of the purified water or the water for injection in the first water storage tank 11 and the second water storage tank 12, ensure that the water temperature delivered to the water using place 30 is appropriate, and at the same time, through the monitoring of the water temperature, it can monitor whether the system operation has abnormal conditions, so that the staff can intervene in time to eliminate potential safety hazards.

[0044] Please continue to refer to Figure 1 , in another embodiment, cleaning devices 80 are installed on the tops of the water storage cavities of the first water storage tank 11 and the second water storage tank 12, and the cleaning devices 80 are used to clean the side walls of the water storage cavities. By installing the cleaning devices 80, the water storage cavities of the first water storage tank 11 and the second water storage tank 12 can be cleaned regularly, thereby ensuring clean water use.

[0045] Specifically, the cleaning device 80 includes a spray head 82, a connecting joint, and a driver 81 for outputting rotational power. The spray head 82 is connected to the rotational drive shaft of the driver 81 through the connecting joint. During operation, the driver 81 drives the spray head 82 to rotate circumferentially 360° in the horizontal plane through the connecting joint, so that the cleaning water sprayed from the spray head 82 can clean all parts of the side wall of the water storage cavity, thereby ensuring the cleaning effect and avoiding residual dead corners.

[0046] Further, to improve the cleaning efficiency, the spraying head 82 is provided with a plurality of water spraying holes, and the plurality of water spraying holes are respectively arranged towards different orientations of the water storage cavity. In this way, the side wall area of the water storage cavity that can be sprayed and washed per unit time can be greatly increased, saving the cleaning time and cycle.

[0047] In the present application, the water usage place 30 can be a production workshop, a laboratory, etc. The water usage place 30 includes a plurality of water supply points 31, and a water intake valve 32 is provided at each water supply point 31. For example, different water supply points 31 can be respectively installed in different rooms, and by switching the water intake valve 32, it is convenient to meet the water usage requirements of different people in different positions.

[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0049] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
