DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-5 The present application provides a technical solution: a double-system water-cooled machine, comprising a water tank 1, a water receiving tray 4, a circulating water system one 5 and a circulating water system two 6. The water tank 1 is arranged inside the water receiving tray 4, a temperature insulation layer 3 is arranged in the middle of the inside of the water tank 1, the temperature insulation layer 3 divides the water tank 1 into two different chambers, the two different chambers of the water tank 1 are connected by a pipe, the circulating water system one 5 and the circulating water system two 6 are respectively located in the two different chambers of the water tank 1, one side of the water tank 1 is provided with a water outlet 40, a valve is arranged on the water outlet 40, and an overflow port 41 is formed on the top side of the water tank 1.

[0033] Vibrators are arranged at the bottom of the two groups of chambers (not shown in the figure).

[0034] The circulating water system 1 comprises a condenser pipe group and a water circulating pipe group. The condenser pipe group comprises a process cooling water system 36, an inlet pipe 1, an inlet pipe 2, an outlet pipe 1 and an outlet pipe 2. The inlet pipe 2 and the outlet pipe 2 are connected with a coil pipe 11 arranged in the water tank 1. The inlet pipe 1 and the outlet pipe 1 are connected with the process cooling water system 36. The inlet pipe 1 and the outlet pipe 1 are connected with a high efficiency tank 7. The other end of the high efficiency tank 7 is connected with the inlet pipe 2 and the outlet pipe 2. The coil pipe 11 and the process cooling water system 36 form a loop through the inlet pipe 1, the inlet pipe 2, the outlet pipe 1, the outlet pipe 2 and the high efficiency tank 7.

[0035] The inlet pipe 1 is connected with a filter 17, a gate valve 1 and a water inlet temperature probe 14 in sequence from the process cooling water system 36 to the high efficiency tank 7. The inlet pipe 2 is connected with a drying filter 8 and a capillary tube 9 in sequence from the high efficiency tank 7 to the coil pipe 11.

[0036] The outlet pipe 1 is connected with a gate valve 2 and a water outlet temperature probe 15 in sequence from the process cooling water system 36 to the high efficiency tank 7. The outlet pipe 1 is connected with a compressor 10 from the high efficiency tank 7 to the coil pipe 11.

[0037] The outlet pipe 2 and the inlet pipe 2 are connected with an electromagnetic valve 13.

[0038] It should be noted that the process cooling water system 36 is a prior art and will not be described in detail.

[0039] The coil pipe 11 is arranged in the water tank 1 to replace the plate type refrigeration machine. The compressor 10 is started to pump the refrigerant in the outlet pipe 2 into the high efficiency tank 7 and then into the inlet pipe 2 to form a loop with the coil pipe 11. Since the cooling liquid in the process cooling water system 36 flows through the inlet pipe 1, the high efficiency tank 7 and then back to the process cooling water system 36 from the outlet pipe 1, the refrigerant in the outlet pipe 2 can be cooled by the low temperature in the high efficiency tank 7. When the refrigerant passes through the drying filter 8 and then enters the capillary tube 9, the refrigerant is further cooled by the capillary tube 9. The refrigerant passing through the coil pipe 11 cools the liquid in the water tank 1 to control the temperature in the water tank 1 to 0.1 Celsius.

[0040] It should be noted that when the temperature of the refrigerant is still low, the electromagnetic valve 13 is opened to make the refrigerant directly pass through the electromagnetic valve 13 and then enter the outlet pipe 2 for circulation.

[0041] The water circulation pipeline set comprises a client device 2, one side of the client device 2 is connected with a main outlet pipe two 38 and a water inlet pipe 39, one end of the main outlet pipe two 38 is connected with a pre-adjustment three-way valve 23, the other two ends of the pre-adjustment three-way valve 23 are respectively connected with a return pipe one 29 and a main outlet pipe one 33, the water inlet pipe 39 is connected with the return pipe one 29, the water inlet pipe 39 is connected with an anti-inverted tank electric ball valve 26, the return pipe one 29 is connected with a total flow sensor 27, the main outlet pipe two 38 is sequentially connected with a gate valve three 25, an electric conductivity sensor 28 and a water outlet flow sensor 24, one end of the return pipe one 29 is arranged in the inside of a water tank 1.

[0042] The main outlet pipe one 33 is sequentially connected with a water pressure sensor 22, a water outlet temperature control probe 21, an electric heating group 19 and a water pump 18, one end of the main outlet pipe one 33 is connected in the water tank 1.

[0043] One end of the main outlet pipe one 33 is connected with a return pipe two 34, the return pipe two 34 is connected with a differential pressure bypass valve 20.

[0044] The inside of the water tank 1 is provided with a water level sensor 12, the water level sensor 12 detects the liquid level in the water tank 1, when the liquid level in the water tank 1 is lower than the set liquid level, the anti-inverted tank electric ball valve is opened, the liquid of the client device 2 is transmitted to the return pipe one 29 through the water inlet pipe 39, the liquid flow into the water tank 1 is detected by the total flow sensor 27, and the liquid flow into the water tank 1 is controlled in a suitable range.

[0045] Embodiment 1

[0046] When the liquid temperature in the water tank 1 is reduced, the water pump 18 is started to pump the liquid in the water tank 1 into the pre-adjustment three-way valve 23 through the main outlet pipe one 33, when the liquid passes through the main outlet pipe one 33, the liquid is heated by the electric heating group, the liquid on the main outlet pipe one 33 is heated, when the liquid is heated to the temperature required by the client, the liquid enters the main outlet pipe two 38 through the pre-adjustment three-way valve 23, and then enters the client device 2 for use by the client. When the temperature does not meet the requirements of the client device, the pre-adjustment three-way valve 23 is opened, the channel of the main outlet pipe two 38 is closed, and the channel of the return pipe two 34 is opened, so that the liquid that does not meet the requirements is returned to the water tank 1. Through the step, the temperature of the outgoing liquid can be adaptively regulated and controlled, so that the temperature required by the user reaches the requirements, and the precision of the liquid temperature required by the user is further improved.

[0047] When the liquid passes through the water outlet flow sensor 24 on the main outlet pipe two 38, the liquid flow is detected in real time, so that the outgoing liquid flow is in a suitable range.

[0048] When the liquid main outlet pipe 1 33 is passed, the water pressure is detected by the water pressure sensor 22, and when the detected water pressure is greater than the preset hydraulic pressure, the differential pressure bypass valve 20 is opened to release the liquid in the main outlet pipe 1 33 to the return pipe 2 34, and then into the water tank 1, ensuring that the output hydraulic pressure is normal.

[0049] Further explanation, the circulating water system 2 6 is consistent with the structure of the circulating water system 1 5, the difference is that the circulating water system 2 6 is provided with two or more groups of electric heating groups, the circulating water system 1 5 is used for 1.5KW circulating water system, the circulating water system 2 6 is used for 6.5KW circulating water system, both are used together, play a role in energy saving, and both are arranged in the same equipment to reduce the floor area.

[0050] Example 2

[0051] When the water level sensor 1 2 identifies that the liquid level in the water tank 1 is lower than the normal value, the anti-inverted tank electric ball valve 2 6 is opened to make the liquid return to the water tank 1, and the total flow sensor 2 7 is used to detect the flow into the water tank 1 in real time during the return process, and the total liquid flow into the water tank 1 is recorded as L, ensuring that the liquid in the water tank 1 is always at a normal liquid level.

[0052] When the water level sensor 1 2 detects that the liquid level is higher than the set liquid level normal value, the valve on the drain 40 is opened, and the excess liquid in the water tank 1 is discharged into the water pan 4.

[0053] In this process, the total liquid flow L is always a constant value, and the water outlet flow sensor 2 4 detects that the water outlet flow is constant, and the water level is always higher than the set liquid level normal value (in normal circumstances, it will ensure that the liquid level in the chamber of the water tank 1 is always at the set normal value), but lower than the overflow port 4 1, indicating that the drain 40 is not easy to drain, proving that there are impurities in the liquid in the water tank 1, and the water in the water tank 1 needs to be replaced.

[0054] Specifically, because the water tank 1 is provided with two groups of different chambers, when one of the chambers needs to be replaced with water due to impurities, the liquid in the other chamber can be transferred to the chamber with more impurities through the pipeline to dilute the liquid in the chamber with more impurities, while the other chamber continues to transfer liquid into it, always ensuring that the liquid level in the other chamber is at the set value.

[0055] And the liquid in the chamber with more impurities continues to input the liquid into the other chamber, continues to make the liquid in the chamber more, so that the liquid level is flush with the overflow port 4 1, and then the liquid flows out of the overflow port 4 1 to the water pan 4, and the vibrator is started synchronously, so that the liquid in the chamber is vibrated and mixed, avoiding the impurities in the liquid, better discharging the liquid with impurities from the drain 40, avoiding the difficulty of discharging impurities when replacing the liquid in the chamber.

[0056] Through the above steps, the circulating water system can still operate normally when the liquid in the impurity multi-chamber is replaced, and the work efficiency is ensured.

[0057] A method for using a dual-system water-cooled machine, comprising the following operation steps:

[0058] Step one: start the condensing pipeline group to reduce the temperature of the liquid in the water tank 1.

[0059] Step two: start the circulating water system to adjust the temperature in the water tank 1 to the required temperature of the user and transmit to the client equipment.

[0060] Step two includes the following specific operation steps:

[0061] Step two-a: when the liquid passes through the main outlet pipe one 33, it passes through the electric heating group to warm the liquid on the main outlet pipe one 33, and when the liquid is warmed to the required temperature of the client, it enters the main outlet pipe two 38 through the pre-adjusting three-way valve 23

[0062] Step two-b: when the temperature does not meet the requirements of the client equipment, open the pre-adjusting three-way valve 23, close the channel of the main outlet pipe two 38, and open the channel of the return pipe two 34 to return the liquid that does not meet the requirements to the water tank 1;

[0063] Step two-c: detect the water pressure through the water pressure sensor 22, and when the detected water pressure is greater than the preset hydraulic pressure, open the differential pressure bypass valve 20 to release the liquid in the main outlet pipe one 33 to the return pipe two 34, and then into the water tank 1, to ensure the normal output of the hydraulic pressure.
