[0030] In addition, the settling tank 106 is connected with an intermediate pipe 104 between the separation cylinder 101, and the intermediate pipe 104 is further connected with a liquid discharge pipe 105 for discharging liquid impurities.
[0031] Preferably, the discharge pipe 107 is further provided with a discharge valve 108, and the liquid discharge pipe 105 is provided with a water stop valve 109.
[0032] The separation cylinder 101 is fixedly connected with a support frame 110, and the separation cylinder 101 and the settling tank 106 are further fixedly connected with a fixing rod 111. The fixing rod 111 can be connected with a wall or other support structure to maintain the stability of the separation cylinder 101 and the settling tank 106.
[0033] By setting a very high separation cylinder 101, the liquid impurities in the oil for water chiller are separated, and the oil for water chiller enters the separation cylinder 101 and is allowed to stand for a period of time, so that the oil and other liquids are stratified, mainly water. Since the oil floats on water, the lower layer of the separation cylinder 101 is water and the upper layer is oil. Liquid separation is thus facilitated.
[0034] The spindle-shaped settling tank 106 is further provided at the bottom of the separation cylinder 101, and the separated solid impurities finally settle in the settling tank 106, and are finally discharged through the discharge pipe 107 at regular intervals.

[0042] In addition, a spindle-shaped settling tank 106 is arranged at the bottom of separation cylinder 101, and the separated solid impurities will finally settle in settling tank 106, and finally the solid impurities are periodically discharged through discharge pipe 107.In addition, vibration motor 115 is arranged on filter plate 114, which can shake off the solid impurities adsorbed on filter plate 114, so that they settle down.In addition, discharge pipe 105 is arranged on intermediate pipe 104 connected between settling tank 106 and separation cylinder 101, which is used to discharge liquid impurities.
