Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery and related equipment, in particular to a device for efficiently detecting blockage of the water pipe of the evaporator of a water cooler. Background Art

[0002] In the tobacco industry, foreign object detection and rejection devices often use water-cooled units for cooling and heat dissipation. The water source used by the water cooler is urban domestic water, which contains more impurities and particulate matters. The impurities in the water will gradually precipitate on the inner wall of the pipeline during the flow through the pipeline, forming scale. In severe cases, it will cause the water pipe to be blocked, the cooling water cannot flow smoothly, the cooling effect of the water cooler will be greatly reduced, and even the equipment may overheat and be damaged.

[0003] Patent Application No. CN202321676804.4, a water-cooled machine evaporator drainage device, includes an evaporator, a water tank, an evaporator water inlet, an evaporator water outlet, a water tank water inlet and a water tank water outlet. The water tank water outlet is connected to the evaporator water inlet through a water inlet pipe, and a water pump and a waterway solenoid valve are arranged on the water inlet pipe; the evaporator water outlet is connected to the water tank water inlet through a return water pipe. The return water pipe and the water inlet pipe cannot detect the internal scale condition. When there is a lot of scale on the inner wall of the pipeline, routine descaling is not carried out, which will greatly reduce the cooling effect of the water cooler. Summary of the Utility Model

[0004] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a device for efficiently detecting blockage of the water pipe of the evaporator of a water cooler, so as to solve the problems that the prior art cannot provide scale detection and cannot reflect the blockage condition of the water pipe system of the water cooler in real time.

[0005] The technical solution adopted by the utility model to solve its problems is as follows:

[0006] A device for efficiently detecting blockage of the water pipe of the evaporator of a water cooler includes a water-cooled machine evaporator and a water tank. The water-cooled machine evaporator is communicated with the water tank through a water outlet pipe and a water inlet pipe. An outlet fluid pressure sensor and an inlet fluid pressure sensor are respectively arranged on the water outlet pipe and the water inlet pipe. A water pump is arranged on the water inlet pipe between the water tank and the inlet fluid pressure sensor.

[0007] Through the above solution, when there is a blockage in the water pipe, the resistance of the water flow will increase, which will lead to an increase in the pressure difference before and after the evaporator. Therefore, by setting the outlet fluid pressure sensor on the water outlet pipe and the inlet fluid pressure sensor on the water inlet pipe, the pressure value can be monitored in real time. When the detected pressure difference exceeds a preset threshold, it can be judged that there may be a blockage in the water pipe, and then the blockage in the water pipe can be found in time, avoiding equipment damage or efficiency reduction caused by long-term blockage.

[0008] Further, the water cooler evaporator is provided with a water inlet and a water outlet, the water tank is provided with an inlet and an outlet, one end of the water outlet pipe is communicated with the water outlet, the other end is communicated with the inlet, one end of the water inlet pipe is communicated with the water inlet, and the other end is communicated with the outlet.

[0009] Further, the outlet fluid pressure sensor is connected to the water outlet pipe through an outlet hand valve, and the inlet fluid pressure sensor is connected to the water inlet pipe through an inlet hand valve.

[0010] Through the above further solution, by connecting with hand valves, the relevant fluid channels can be conveniently closed without stopping the operation of the whole system, so as to replace or maintain the outlet fluid pressure sensor and the inlet fluid pressure sensor. This reduces the number of times when the system needs to be completely stopped during maintenance and improves the availability of the system.

[0011] Further, the outlet fluid pressure sensor is perpendicular to the water outlet pipe, and the inlet fluid pressure sensor is perpendicular to the water inlet pipe.

[0012] Through the above further solution, the vertically installed outlet fluid pressure sensor and inlet fluid pressure sensor can reduce the interference to the water flow. Compared with parallel installation, the vertically installed outlet fluid pressure sensor and inlet fluid pressure sensor have less resistance to the water flow, are not easy to form turbulence or eddy current, thus ensuring the smoothness of the water flow and reducing the impact on the system efficiency. The vertically installed outlet fluid pressure sensor and inlet fluid pressure sensor are easier to avoid possible bubbles or impurities, because these bubbles or impurities usually move along the main flow direction, and the vertically installed position can better capture the real fluid pressure rather than being interfered by bubbles or particulate matters, thereby improving the measurement accuracy and reliability, and making the installation and disassembly of the outlet fluid pressure sensor and the inlet fluid pressure sensor more convenient.

[0013] Further, a main solenoid valve is provided on the water inlet pipe between the water pump and the inlet fluid pressure sensor.

[0014] Through the above further solution, by controlling the on-off state of the main solenoid valve, the water flow can be accurately controlled as needed. When cooling is not required or the cooling demand is low, the solenoid valve can be closed to save energy and reduce the unnecessary operation of the water pump at the same time.

[0015] Further, a branch pipe is provided on the water inlet pipe between the inlet fluid pressure sensor and the main solenoid valve. The branch pipe is connected end-to-end with an air compressor at the connection end with the water inlet pipe, and a compressed air solenoid valve is provided on the branch pipe.

[0016] Through the above further solution, the compressed air provided by the air compressor can blow out the water in the water inlet pipe, the water outlet pipe and the evaporator of the water cooler. Then, through the compressed air provided by the air compressor, the water inlet pipe, the water outlet pipe and the evaporator of the water cooler can be purged regularly or as needed to remove the dirt or deposits in the pipeline and keep the water flow smooth.

[0017] Further, a first solenoid valve is provided at one end of the water outlet pipe close to the water tank. A descaling pipe is provided between the first solenoid valve and the outlet fluid pressure sensor on the water outlet pipe. The descaling pipe is close to the first solenoid valve, and a second solenoid valve is provided on the descaling pipe.

[0018] Through the above further solution, when descaling the water inlet pipe, the water outlet pipe and the evaporator of the water cooler, the first solenoid valve can be closed to cut off the water flow from the evaporator to the water tank, and then the second solenoid valve can be opened to discharge the removed dirt from the descaling pipe.

[0019] In summary, an efficient device for detecting blockage of the water pipe of the evaporator of a water cooler provided by the present utility model has the following technical effects:

[0020] 1. By providing an outlet fluid pressure sensor on the water outlet pipe and an inlet fluid pressure sensor on the water inlet pipe, the pressure value can be monitored in real time. When the detected pressure difference exceeds a preset threshold, it can be determined that there may be a blockage in the water pipeline, and thus the blockage in the water pipeline can be detected in time to avoid equipment damage or efficiency reduction caused by long-term blockage.

[0021] 2. Through the compressed air provided by the air compressor, the water in the water inlet pipe, the water outlet pipe and the evaporator of the water cooler can be blown out. Then, through the compressed air provided by the air compressor, the water inlet pipe, the water outlet pipe and the evaporator of the water cooler can be purged regularly or as needed to remove the dirt or deposits in the pipeline and keep the water flow smooth.

In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Embodiment 1:

[0030] Refer to Figure 1As shown in the figure, an efficient device for detecting blockage in the water pipe of a water chiller evaporator includes a water chiller evaporator 1 and a water tank 2. The water chiller evaporator 1 is provided with a water inlet 11 and a water outlet 12, and the water tank 2 is provided with an inlet 21 and an outlet 22. One end of the outlet pipe 4 is connected to the water outlet 12, and the other end is connected to the inlet 21. One end of the inlet pipe 3 is connected to the water inlet 11, and the other end is connected to the outlet 22. An outlet fluid pressure sensor 41 and an inlet fluid pressure sensor 31 are respectively provided on the outlet pipe 4 and the inlet pipe 3. A water pump 32 is provided on the inlet pipe 3 between the water tank 2 and the inlet fluid pressure sensor 31. When there is a blockage in the water pipe, the resistance of the water flow will increase, which will lead to an increase in the pressure difference before and after the evaporator. Therefore, by setting the outlet fluid pressure sensor 41 on the outlet pipe 4 and the inlet fluid pressure sensor 31 on the inlet pipe 3, the pressure value can be monitored in real time. When the detected pressure difference exceeds a pre-set threshold, it can be judged that there may be a blockage in the water pipe, and then the blockage in the water pipe can be discovered in time, avoiding equipment damage or efficiency reduction caused by long-term blockage.

[0031] Among them, the outlet fluid pressure sensor 41 is connected to the outlet pipe 4 through an outlet manual valve 411, and the inlet fluid pressure sensor 31 is connected to the inlet pipe 3 through an inlet manual valve 311. By connecting with manual valves, the relevant fluid channels can be conveniently closed without stopping the operation of the whole system, so as to replace or maintain the outlet fluid pressure sensor 41 and the inlet fluid pressure sensor 31. This reduces the number of times when the system needs to be completely stopped during maintenance and improves the usability of the system.

[0032] It should be noted that the outlet fluid pressure sensor 41 is perpendicular to the outlet pipe 4, and the inlet fluid pressure sensor 31 is perpendicular to the inlet pipe 3, that is, the pipe where the outlet fluid pressure sensor 41 is located is perpendicular to the outlet pipe 4, and the pipe where the inlet fluid pressure sensor 31 is located is perpendicular to the inlet pipe 3. The vertically installed outlet fluid pressure sensor 41 and inlet fluid pressure sensor 31 can reduce the interference to the water flow. Compared with parallel installation, the vertically installed outlet fluid pressure sensor 41 and inlet fluid pressure sensor 31 have less resistance to the water flow, are not easy to form turbulence or eddy currents, thus ensuring the smoothness of the water flow and reducing the impact on the system efficiency. The vertically installed outlet fluid pressure sensor 41 and inlet fluid pressure sensor 31 are easier to avoid possible bubbles or impurities, because these bubbles or impurities usually move along the main flow direction. The vertically installed position can better capture the real fluid pressure instead of being interfered by bubbles or particles, thereby improving the accuracy and reliability of the measurement, and making the installation and disassembly of the outlet fluid pressure sensor 41 and the inlet fluid pressure sensor 31 more convenient.

[0033] Among them, a main solenoid valve 33 is provided on the water inlet pipe 3 between the water pump 32 and the inlet fluid pressure sensor 31. By controlling the on / off state of the main solenoid valve 33, the water flow rate can be precisely controlled as needed. When cooling is not required or the cooling demand is low, the solenoid valve can be closed to save energy and reduce the unnecessary operation of the water pump 32 at the same time.

[0034] The working principle of the first embodiment is as follows:

[0035] When the water-cooled chiller evaporator 1 is in the water inlet stage, the water-cooled chiller works normally, the water pump 32 is in the running state, and the main solenoid valve 33 is in the open state. The water in the water tank 2 is pumped into the water-cooled chiller evaporator 1 through the water inlet pipe 3 by the power of the water pump 32, and then can pass through the inlet fluid pressure sensor 31, and then enter the water tank 2 through the water outlet pipe 4, and then can pass through the outlet fluid pressure sensor 41. When there is a blockage in the water pipeline, the resistance of the water flow will increase, which will cause the pressure difference before and after the evaporator to increase. Therefore, by setting the outlet fluid pressure sensor 41 on the water outlet pipe 4 and the inlet fluid pressure sensor 31 on the water inlet pipe 3, the pressure value can be monitored in real time. When the detected pressure difference exceeds the preset threshold, it can be judged that there may be a blockage in the water pipeline, and then the blockage in the water pipeline can be discovered in time.

[0036] Embodiment Two:

[0037] Referring to Figure 2 As shown, on the basis of the first embodiment, a branch pipe 5 is provided on the water inlet pipe 3 between the inlet fluid pressure sensor 31 and the main solenoid valve 33. The connection end of the branch pipe 5 to the water inlet pipe 3 is connected end-to-end with an air compressor 51. A compressed air solenoid valve 52 is provided on the branch pipe 5. Through the compressed air provided by the air compressor 51, the water in the water inlet pipe 3, the water outlet pipe 4 and the water-cooled chiller evaporator 1 can be blown out. Then, through the compressed air provided by the air compressor 51, the water inlet pipe 3, the water outlet pipe 4 and the water-cooled chiller evaporator 1 can be purged regularly or as needed to remove dirt or deposits in the pipeline and keep the water flow smooth.

[0038] A first solenoid valve 42 is provided at one end of the water outlet pipe 4 close to the water tank 2. A descaling pipe 6 is provided in the middle of the water outlet pipe 4 between the first solenoid valve 42 and the outlet fluid pressure sensor 41. The descaling pipe 6 is close to the first solenoid valve 42. A second solenoid valve 61 is provided on the descaling pipe 6. When descaling the water inlet pipe 3, the water outlet pipe 4 and the water-cooled chiller evaporator 1, the first solenoid valve 42 can be closed to cut off the water flow from the evaporator to the water tank 2, and then the second solenoid valve 61 can be opened to discharge the removed dirt from the descaling pipe 6.

[0039] It should be noted that the water-cooled chiller evaporator 1 specifically refers to the pipeline in the water-cooled chiller evaporator 1 that is connected to the water outlet pipe 4 and the water inlet pipe 3.

[0040] The working principle of the second embodiment is as follows:

[0041] When scale removal is required for the water inlet pipe 3, the water outlet pipe 4, and the water chiller evaporator 1, the water pump 32 and the main solenoid valve 33 are closed, the air compressor 51 and the compressed air solenoid valve 52 are opened, the first solenoid valve 42 is in the open state, and the second solenoid valve 61 is in the closed state. The water in the water inlet pipe 3, the water outlet pipe 4, and the water chiller evaporator 1 is blown into the water tank 2 by the compressed air provided by the air compressor 51. After a certain period of time, the first solenoid valve 42 is closed, the second solenoid valve 61 is opened, the pressure of the air blown out by the air compressor 51 is increased, and the scale on the inner parts of the water inlet pipe 3, the water outlet pipe 4, and the water chiller evaporator 1 is cleaned. The scale will be discharged from the scale discharge pipe 6. After the cleaning is completed, the second solenoid valve 61, the air compressor 51, and the compressed air solenoid valve 52 are closed.

[0042] When the water chiller is working, the first solenoid valve 42, the water pump 32, and the main solenoid valve 33 are in the open state; the second solenoid valve 61, the air compressor 51, and the compressed air solenoid valve 52 are in the closed state.

[0043] As mentioned above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
