[0031] See also Figure 1-4 A coolant supply device for a machining workshop comprises an outer frame 1, the inner wall of the outer frame 1 is fixedly connected to a coolant tank 2, the upper surface of the outer wall of the coolant tank 2 is fixedly connected to a high-pressure pump 4 and an electric control box 16, the input end of the high-pressure pump 4 is fixedly connected to and communicated with a pump suction pipe 12, the other end of the pump suction pipe 12 is fixedly connected to the outer wall of the coolant tank 2 and communicated with the interior of the coolant tank 2, the output end of the high-pressure pump 4 is fixedly connected to and communicated with a liquid outlet pipe 6, the other end of the liquid outlet pipe 6 is connected to a filter assembly, the other end of the filter assembly is connected to a connecting pipe 8, the other end of the connecting pipe 8 is fixedly connected to and communicated with a diverter valve 9, and the other end of the diverter valve 9 is fixedly connected to and communicated with a plurality of liquid diverter pipes 11.

[0032] like Figures 1 to 4 As shown, when the coolant supply device for a machining workshop in the utility model is in use, it is only necessary to connect the ends of several liquid diversion pipes 11 away from the diversion valve 9 to several external devices that need to add coolant, and then turn on the high-pressure pump 4 through the internal controller of the electric control box 16 (this is the prior art, the most common one is the PLC controller, of course, other controllers can also be used, and the specific details are not limited). After the high-pressure pump 4 is started, according to its own working characteristics, the coolant can be drawn from the inside of the coolant tank 2 through the pump suction pipe 12, and then enter the diversion valve 9 through the liquid outlet pipe 6, the filter assembly and the connecting pipe 8, and then be diverted by the diversion valve 9 and transported to different devices for adding coolant. It is simple and easy to operate.

[0033] It should be particularly noted here that the plurality of liquid diversion pipes 11 can be directly connected to the diversion valve 9, or can be diverted through a three-way pipe, a four-way pipe, etc., without any specific limitation.

[0034] like Figure 1-Figure 4 As shown, the filter assembly includes a bracket 5 and an air filter 7, one end of the bracket 5 is fixedly connected to the upper surface of the outer wall of the coolant tank 2, the other end of the bracket 5 is fixedly connected to the outer wall of the air filter 7, the two ends of the air filter 7 are respectively fixedly connected to the liquid outlet pipe 6 and the connecting pipe 8, and the air filter 7 is connected to the inside of the liquid outlet pipe 6 and the connecting pipe 8.

[0035] More specifically, by providing a filter assembly, impurities in the coolant can be filtered out when the coolant passes through, thereby increasing the filtering effect.

[0036] The specific method is: the coolant enters the air filter 7 through the liquid outlet pipe 6, and then is filtered through the air filter 7, so as to absorb and filter out the impurities contained in the coolant. After that, the coolant transmitted from the connecting pipe 8 will be cleaner and purer, so that the subsequent coolant can be more efficient when cooling external equipment.

[0037] It should be noted that the filter element inside the air filter 7 is replaceable, so that the air filter 7 can be taken out and cleaned or replaced after being used for a period of time.

[0038] like Figure 1-Figure 3 As shown, a coolant adding pipe 3 is fixedly connected to the upper surface of the outer wall of the coolant tank body 2 , and the coolant adding pipe 3 is communicated with the interior of the coolant tank body 2 .

[0043] More specifically, by providing the tank pressure gauge 18, the internal pressure of the coolant tank 2 can be monitored and known in real time.

[0044] like Figure 1-Figure 3 As shown, a diverter valve pressure gauge 10 is fixedly connected to the upper surface of the outer wall of the diverter valve 9 , and the diverter valve pressure gauge 10 is communicated with the inside of the diverter valve 9 .

[0045] More specifically, by providing the diverter valve pressure gauge 10 , the internal pressure of the diverter valve 9 can be monitored and known in real time.

[0047] More specifically, by providing the pump overflow pipe 13 , the excess coolant pumped out can be recovered into the coolant tank 2 again to protect the high-pressure pump 4 and reduce the probability of damage to the high-pressure pump 4 .

[0048] like Figure 3 and Figure 4 As shown, a liquid filter 19 is fixedly connected to the upper surface of the outer wall of the coolant tank 2 , and the liquid filter 19 is communicated with the interior of the coolant tank 2 .

[0049] More specifically, by providing the liquid filter 19, the coolant inside the coolant box 2 can be filtered in advance. It should be noted that the liquid filter 19 is the same as the air filter 7 and is of detachable design.
