Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present application.
The core of the application is to provide a cooling device based on vacuum sublimation purification equipment.
In order to better understand the aspects of the present application, the present application will be described in further detail with reference to the accompanying drawings and detailed description.
In the practical application of the vacuum sublimation purification equipment, the required cooling conditions of different equipment to be cooled are different, even the same equipment to be cooled is different in different working states or different environments, so that if the refrigerator is used for refrigerating water in a water tank only by means of preset temperature, the cooling requirements of the equipment to be cooled under different conditions cannot be well met, and the temperature of the water pipe surface is too low only by simply selecting low temperature refrigeration, so that water vapor in air is condensed on the water pipe surface, the humidity around the equipment to be cooled is improved, the purity of a target substance to be purified is seriously influenced, and electric energy is wasted. Accordingly, the present application provides a cooling device based on vacuum sublimation purification equipment, as shown in fig. 1, comprising: the refrigerating machine 1, the water pump 2, the control unit 3, the temperature sensor 4, the cooling pipeline 5 and the valve 6;
the refrigerator 1 is connected with the cooling pipeline 5 and the control unit 3 and is used for cooling water in the cooling pipeline 5 to a specified temperature according to a temperature control signal sent by the control unit 3; the water pump 2 is connected with a cooling pipeline 5; the cooling pipelines 5 are arranged at the positions of the equipment to be cooled in a surrounding manner, the cooling pipelines 5 are internally provided with valves 6, and the valves 6 are used for separating the cooling pipelines 5 for cooling different equipment to be cooled; each cooling pipeline 5 for cooling different equipment to be cooled is internally provided with a temperature sensor 4, and the temperature sensor 4 is connected with the control unit 3.
Regarding the temperature sensor 4, one preferred way is: the temperature sensor 4 selects a water temperature sensor with the precision of 0.1 ℃ to acquire more accurate water temperature information, so that the control unit 3 can conveniently control the water temperature.
In fig. 1, a cooling pipeline 5 with a hollow tubular structure is shown by a double solid line, a dotted line is shown in communication connection, the cooling pipeline 5 is divided into different branches through a valve 6, each branch is used for cooling a device to be cooled, and a temperature sensor 4 on each branch is in communication connection with a control unit 3. In addition, although the cooling pipes 5 at the location of the device to be cooled are disposed around the device to be cooled, in view of the manner of disposing the cooling pipes 5 that is well known in the art, the connection of the cooling pipes 5 to the device to be cooled in fig. 1 is only a simplified schematic diagram, and in practical application, a suitable method for disposing the cooling pipes 5 at the location of the device to be cooled should be selected according to needs. Meanwhile, fig. 1 only shows the case of dividing the cooling pipeline 5 into two branches through the valve 6, but it is easy to know that the arrangement mode of more branches is the same, and no description is repeated here.
In this embodiment, the type of the cooling liquid in the cooling line 5 is not limited, and may be freely selected according to actual needs, but in view of cost and the like, the cooling liquid is generally water, and in the following description, water is also taken as an example. Furthermore, the water inlet shown in fig. 1 may be connected to a water source or supply, the water outlet may be connected to the outside or reservoir, and a preferred embodiment is: the water outlet and the water inlet are connected with the same water tank. Therefore, the water circulation in the cooling pipeline 5 is realized, and the water resource is further saved.
Meanwhile, a cooling device based on vacuum sublimation purification equipment shown in fig. 1 is only one simplest implementation form, cooling and circulation of water are realized through one refrigerator 1 and one water pump 2, but in practice, one refrigerator 1 and a plurality of water pumps 2 can be configured, and each water pump 2 controls the flow rate of water in different branches; a water pump 2 and a plurality of refrigerators 1 can also be configured, and each refrigerator 1 controls the temperature of water in different branches; a plurality of water pumps 2 and a plurality of refrigerators 1 can also be configured, and the flow rate and the temperature of each branch water are respectively controlled by the control unit 3 so as to obtain better cooling effect.
In addition, the present embodiment is not limited to the type and operation control manner of the valve 6, and may be a butterfly valve, a gate valve, a ball valve, a check valve, manual operation, electric operation, hydraulic operation, or the like, and may be freely selected according to actual needs, so as to satisfy the cooling lines 5 capable of separating different branches.
According to the cooling device based on the vacuum sublimation purification equipment, the temperature sensors 4 which are in communication connection with the control unit 3 are respectively arranged in the branches separated by the valve 6, so that the control unit 3 can obtain the water temperatures in the cooling pipelines 5 for cooling different equipment to be cooled, the power of the refrigerator 1 and the water pump 2 is changed according to actual needs, the temperature and the flow rate of water in the cooling pipelines 5 are further changed, better cooling effect is achieved, meanwhile, electric energy waste caused by setting lower temperature for the refrigerator 1 is avoided, and the problem that the ambient environment humidity of the vacuum sublimation purification equipment is increased and the purity of products is affected because the temperature of the cooling pipelines 5 is too low and water vapor is condensed at the outer wall is solved. In addition, the application separates the cooling pipelines 5 for cooling different devices to be cooled through the valve 6, and realizes more targeted cooling through controlling the opening and closing degree of the valve 6 so as to achieve better cooling effect.
Since the cooling requirements of different devices to be cooled are not necessarily the same in the vacuum sublimation purification device, as shown in fig. 2, this embodiment provides a preferred embodiment, and the connection between the water pump 2 and the cooling pipeline 5 is specifically:
each cooling pipeline 5 for cooling different equipment to be cooled is connected with a different water pump 2.
The power of the water pump 2 is determined by the requirement of the equipment to be cooled on the branch where the water pump 2 is located, and the power of the water pump 2 can be set in advance and can also be controlled by the control unit 3, which is not limited in this embodiment, but in general, in order to adapt to the more complex cooling requirement, a preferred scheme is as follows:
the water pump 2 is a variable-frequency water pump and is connected with the control unit 3 and is used for controlling the flow rate of water in the cooling pipeline 5 according to the flow rate control signal sent by the control unit 3.
Under the certain condition of the water temperature in the cooling pipeline 5, if the cooling requirement is that the equipment to be cooled needs faster cooling at present, then the control unit 3 sends control signal to the variable frequency water pump, improves the power of variable frequency water pump to improve the water flow rate in the current cooling pipeline 5, likewise, the control unit 3 also can control the variable frequency water pump power to reduce in order to practice thrift the electric energy consumption according to the cooling requirement.
In this embodiment, through the cooling pipeline 5 where the cooling equipment is located to different waiting, set up different water pumps 2 respectively to realize the differentiation control of the water velocity in the cooling pipeline 5 of different branches, and then satisfy the different cooling demands of the cooling equipment that wait in the difference. The variable-frequency water pump can be more suitable for different cooling requirements relative to the fixed-power water pump 2, and in addition, the output power of the variable-frequency water pump can be reduced when the cooling requirements are not high, so that the purpose of saving electric energy is achieved.
As can be seen from the foregoing, in the above embodiment, the differential control of the flow rate is realized by setting different water pumps 2 at different branches of the cooling pipeline 5, and the flow rate of the water in the cooling pipeline 5 is also an important index affecting the cooling capability, so as shown in fig. 2, the embodiment further provides a preferred embodiment, and the cooling device of the vacuum sublimation purifying apparatus further includes: a flow meter 7;
each cooling pipeline 5 for cooling different cooling equipment is internally provided with a flowmeter 7, and the flowmeter 7 is connected with the control unit 3 and is used for returning the flow velocity information of the current cooling pipeline 5.
The present embodiment is not limited to the type, model, specification, etc. of the flowmeter, but provides a preferred solution for the flowmeter: the flowmeter 7 with the maximum measuring range not lower than 10 meters per second is selected.
In this embodiment, the flow meters 7 are disposed in the cooling pipes 5 of different branches, but the further disposition is not limited, and generally, the flow meters 7 are disposed at the inner wall of the cooling pipes 5. However, because the cooling pipeline 5 of the same branch may not have the same flow velocity of water in the pipeline due to the factors such as bending the pipeline, the embodiment also provides a preferable scheme for more accurate measurement of the flow velocity of water cooled by the cooling device: the flowmeter 7 is arranged at the inner wall of the cooling pipeline 5 surrounding the equipment to be cooled.
The control unit 3 is in communication connection with each flowmeter 7, and is configured to obtain flow velocity information of each branch returned by each flowmeter 7, and further adjust a cooling temperature of the refrigerator 1 according to a cooling requirement determined by information returned by the temperature sensor 4. Or the output power of the variable-frequency water pump in the embodiment is adjusted to achieve the purpose of adjusting the water flow rate in the cooling pipeline 5.
In addition, it should be noted that fig. 2 shows a schematic structural diagram of a cooling device based on a vacuum sublimation purifying apparatus, but the relative relationship between the positions of the refrigerator 1, the water pump 2, the temperature sensor 4 and the flow meter 7 shown in fig. 2 is not limited, and fig. 2 is only a reference case. However, in general, the refrigerator 1, the water pump 2, the temperature sensor 4, and the flow meter 7 should be disposed upstream of the equipment to be cooled from the viewpoint of the flow direction of the water in the piping.
In this embodiment, the flow meters 7 connected with the control unit 3 are respectively disposed in the cooling pipelines 5 of different branches, so that the control unit 3 can know the flow rate of water in the cooling pipeline 5 for cooling each device to be cooled, and adjust the refrigeration temperature of the refrigerator 1 or the output power of the water pump 2 according to the flow rate information and the temperature information returned by the temperature sensor 4, so as to realize more refined cooling control.
From the above, the sensor is disposed in the cooling pipeline 5 closer to the cooling device, and the obtained information can be reflected to the flow rate and temperature of the water cooled by the cooling device. Also based on the above consideration, the above embodiment sets the flowmeter 7 on the inner wall of the cooling pipeline 5 at the position of the equipment to be cooled, so for the further setting position of the temperature sensor 4, this embodiment also provides a preferred embodiment, and each cooling pipeline 5 for cooling different equipment to be cooled is provided with the temperature sensor 4 specifically as follows: the temperature sensor 4 is arranged on the inner wall of the cooling pipeline 5 at the position of the equipment to be cooled.
According to the embodiment, the temperature sensor 4 is arranged at the equipment to be cooled in the cooling pipeline 5, so that the water temperature in the current branch is detected more accurately, and the control unit 3 can control the cooling process more accurately according to the temperature information returned by the temperature sensor 4.
In addition to the above-mentioned embodiments in which different water pumps 2 are disposed on the branches where different devices to be cooled are located, as shown in fig. 2, this embodiment further provides a preferred embodiment, where the connection between the refrigerator 1 and the cooling pipeline 5 is specifically: each cooling pipeline 5 for cooling different equipment to be cooled is connected with a different refrigerator 1.
In order to further reduce energy consumption, the refrigerator 1 in this embodiment is preferably a variable frequency refrigerator, and is connected to the control unit 3, and after the control unit 3 obtains the water temperature corresponding to the current to-be-cooled device according to the received temperature information or flow information of each to-be-cooled device, the control unit further sends a control signal to the variable frequency refrigerator to enable the variable frequency refrigerator to reduce the water in the cooling pipeline 5 to a specified temperature.
Because the cooling pipelines 5 between different branches are separated by the valve 6, the water in the cooling pipelines 5 is not communicated until the equipment to be cooled is cooled, so that the water in the cooling pipelines 5 of different branches can have different water temperatures and flow rates, in the embodiment, a preferable scheme that each branch is respectively provided with different water pumps 2 is provided to realize the purpose of controlling the flow rate of the water in each branch, and the embodiment can realize the purpose of controlling the temperature of the water in each branch by arranging different refrigerators 1 on each branch, thereby realizing targeted cooling for each equipment to be cooled with different cooling demands and achieving better cooling effect.
To further illustrate the apparatus provided by the present application, on the basis of the above examples, the present examples also provide a preferred embodiment as follows: the valve 6 is a check valve.
The check valve is a one-way valve that allows liquid medium to flow through the check valve only from the same direction, but prevents liquid medium from flowing in the opposite direction. The check valve belongs to an automatic valve, no external control is needed, the opening and closing of the opening and closing piece in the valve are realized only by the flowing pressure of the liquid medium in the pipeline, and when the liquid medium flows in the flowing direction, the valve clack is opened under the pressure action of the liquid medium; when the liquid medium flows in the opposite direction, the valve clack acts on the valve seat due to the pressure of the liquid medium and the self-gravity of the valve clack, so that the flow of the liquid medium is cut off.
The present embodiment is not limited to the specific type of check valve selected, and may be a straight-through type check valve, a lift type check valve, a swing type check valve, a butterfly type check valve, a diaphragm type check valve, a ball type check valve, or the like.
The check valve can achieve the effect of preventing the backflow of the liquid due to its unique structure. Besides the influence on normal operation of the refrigerator 1 and the water pump 2 caused by water reflux in the cooling pipeline 5 is avoided, water flows can not flow into other branches in a countercurrent mode after flowing into each branch for cooling different equipment to be cooled, water flows of corresponding branches can not influence other branches after acquiring water temperatures and flow rates corresponding to the current branches from the refrigerator 1 and the water pump 2, and then each branch can acquire the water temperatures and flow rates required by the current branch through the corresponding water pump 2 and the refrigerator 1 without considering the influence of other branches, differentiation of cooling control among different equipment to be cooled is further guaranteed, and better cooling effect is achieved.
Besides water cooling through the cooling pipeline 5, natural heat dissipation of the equipment to be cooled is also an important channel for heat discharge, and the cooling requirements of the equipment to be cooled are different at different environmental temperatures. Therefore, in order to better control the cooling process, on the basis of the above embodiment, the embodiment also provides a preferred implementation manner, as shown in fig. 3, the cooling device based on the vacuum sublimation purifying apparatus provided by the application further includes:
and an ambient temperature sensor 8 arranged at the control unit 3, wherein the ambient temperature sensor 8 is connected with the control unit 3 and is used for collecting temperature information of the surrounding environment and returning to the control unit 3.
Because the vacuum sublimation purification equipment works indoors more stably, the ambient temperature around the equipment is stable, and the temperature difference of different positions is not large, the specific setting position of the ambient temperature sensor 8 is not strictly limited, but the ambient temperature is influenced to a certain extent in consideration that the equipment to be cooled is equivalent to a heat source and cooling water flows in the cooling pipeline 5, so that the ambient temperature sensor 8 is arranged at a place far away from the equipment to be cooled and the cooling pipeline 5 for further accurately measuring the ambient temperature. Generally, the control unit 3 is not arranged too close to the equipment to be cooled and the cooling pipeline 5; meanwhile, in order to ensure the control effect, the control unit 3 is arranged on the same factory with the equipment to be cooled; in addition, the ambient temperature sensor 8 needs to be connected to the control unit 3, and is more conveniently arranged closer to the control unit 3. In summary, the environmental temperature sensor 8 is preferably disposed at the control unit 3 in the present embodiment, but it should be noted that the purpose of collecting the environmental temperature by the environmental temperature sensor 8 may be achieved by disposing the environmental temperature sensor at other positions.
The present embodiment collects the ambient temperature by setting the ambient temperature sensor 8, so that the control unit 3 can properly adjust the flow rate and the temperature of the water in the cooling pipeline 5 according to the current ambient temperature, for example, when the ambient temperature is higher, the temperature of the water is reduced or the flow rate of the water is increased, so as to meet the cooling requirement of each device to be cooled. When the ambient temperature is low, the output power of the refrigerator 1 and the water pump 2 can be properly reduced without excessively low water temperature or excessively high flow rate, so that the purposes of energy conservation and emission reduction are achieved, and more refined control on the cooling process is realized.
Similarly, considering that the cooling device provided by the present application is mainly applied to cooling of vacuum sublimation purification equipment, the above also illustrates that too low temperature of the cooling pipeline 5 may cause condensation steam on the outer wall of the pipeline, so that the ambient humidity is further increased, and too high ambient humidity may seriously affect the purity of the product purified by vacuum sublimation, so as shown in fig. 3, the present embodiment also provides a preferred embodiment, and the cooling device based on vacuum sublimation purification equipment provided by the present application further includes:
the humidity sensor 9 is arranged on the outer wall of the cooling pipeline 5, and the humidity sensor 9 is connected with the control unit 3 and is used for collecting humidity information of the surrounding environment and returning to the control unit 3.
When humidity is higher, in order to avoid condensing on the pipeline outer wall because of the low water temperature in cooling pipeline 5 leads to vapor in the air for ambient's vapor can't get rid of, further increases ambient humidity, and then influences product purity, and the control unit 3 can make the temperature suitably improve through the power of adjustment refrigerator 1 to the mode that makes the velocity of flow of cooling pipeline 5 water faster through the mode of control water pump 2, guarantees the cooling effect.
As in the above embodiment, the same way as the setting position of the ambient temperature sensor 8 is that the setting position of the humidity sensor 9 is the same preferred way in this embodiment, and considering that the outer wall of the cooling pipeline 5 is lower than the surrounding environment, and that the water vapor is easier to condense on the outer wall of the cooling pipeline 5, the humidity around the cooling pipeline 5 is also relatively higher, and that the setting of the humidity sensor 9 can detect the rising of the ambient humidity more easily and timely. However, similarly, the humidity sensor 9 is arranged at any position of the environment where the vacuum sublimation purifying device is located, so that the purpose of acquiring the current environmental humidity information can be met, and the position at the outer wall of the cooling pipeline 5 is only one preferred embodiment.
The advantage of this embodiment over the above-described embodiments is that: the humidity information of the surrounding environment of the vacuum sublimation purification equipment is acquired by the humidity sensor 9, when the humidity is too high, the control unit 3 properly reduces the temperature of water in the cooling pipeline 5 and improves the flow rate, so that the problem that the product purity is affected because water vapor in the air cannot be discharged due to the fact that the water temperature is too low and the water vapor in the air is all condensed on the outer wall of the cooling pipeline 5 is avoided while the cooling effect is ensured, and the smooth proceeding of the vacuum sublimation purification process is further ensured.
As can be seen from the above, the control unit 3 can adjust the power of the refrigerator 1 and the water pump 2 according to the water temperature information of each branch of the cooling pipeline 5 acquired by the temperature sensor 4, the environmental temperature information acquired by the environmental temperature sensor 8, and the environmental humidity information acquired by the humidity sensor 9, and the like, so as to achieve the effect of adjusting the water temperature and the flow rate in the cooling pipeline 5, but the control mode is not transparent enough, the operator does not know the condition in the current cooling pipeline 5, and does not know whether the control unit 3 has a fault or error, and has a bad influence on the stability and the reliability of the cooling device, so as shown in fig. 3, on the basis of the above embodiment, the embodiment further provides a preferred embodiment, and the cooling device further includes: a display screen 10;
the display screen 10 is connected to the control unit 3, and is used for displaying temperature information and humidity information of the surrounding environment, refrigeration state of the refrigerator 1 and power information of the water pump 2, which are sent by the control unit 3.
As can be seen from the above, the control unit 3 is communicatively connected to the temperature sensor 4 provided in each place in the cooling pipeline 5, the ambient temperature sensor 8 provided in the control unit 3, the humidity sensor 9 provided on the outer wall of the cooling pipeline 5, the flowmeter 7, the refrigerator 1, the water pump 2, and the like, so as to obtain the water temperature and flow rate, the ambient temperature and the ambient humidity of each branch of the cooling pipeline 5, the refrigeration state of the refrigerator 1, the power information of the water pump 2, and the like. The information is helpful for operators to judge the overall condition of the current cooling device, and accordingly, whether the cooling device fails or not or whether the cooling requirement can be met is judged.
It should be noted that, the information displayed on the display screen 10 in this embodiment is only a preferred embodiment, and the embodiment is not limited thereto if the control unit 3 is connected to other devices or needs to display other data and parameters.
The advantage of this embodiment over the above-described embodiments is that: through setting up information such as temperature, velocity of flow, ambient temperature, ambient humidity, the state of refrigerator 1 and the power of water pump 2 in the display screen 10 demonstration each branch road, the operating personnel of being convenient for grasp the current state of heat sink, and then can carry out the trouble judgement, perhaps rely on the above-mentioned information that obtains to carry out manual control to the cooling process, further improved the reliability and the stability of cooling process.
