The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Referring to fig. 1 and 2, a separator is shown, which comprises a frame 11, a housing 12 is erected on the frame 11, a cavity is formed in the housing 12, an air inlet 121 and an air outlet 122 are formed in the housing 12, a first filter screen, a condenser and a second filter screen are sequentially arranged in the housing 12 and between the air inlet 121 and the air outlet 122, and a waste discharge port 123 is formed in the bottom of the housing 12. In simple terms, the separator 1 may be arranged in an air flow system, with air flow entering from the air inlet 121 of the housing 12 and exiting from the air inlet 121 on the housing 12; the air flow is in the shell 12, the first filter screen and the second filter screen can intercept particle impurities in the air flow, and the structure of a double-layer filter screen can effectively ensure the filtering interception effect; the temperature of the air flow passing through the condenser is reduced, so that water vapor and oily impurities in the air flow can release heat to condensate, and the water and oil after the condensate are collected at the bottom of the shell 12 and can be discharged through a waste discharge port 123 at the bottom of the shell 12, thereby being convenient for maintenance and cleaning.

In the above-mentioned scheme, for convenience of maintenance, the waste outlet 123 is provided with a control valve 124 to control the opening and closing of the waste outlet 123. When the impurities and wastes in the housing 12 accumulate to a certain amount, the control valve 124 may be opened to discharge the impurities and wastes from the waste outlet 123; wherein, the control valve 124 can adopt a ball valve, the ball valve has simple and compact structure and reliable sealing, and the sealing surface and the spherical surface are in a normally closed state and are not easy to be eroded by a medium, thereby avoiding being eroded by oily impurities. Of course, other existing valve bodies can be adopted according to actual needs.

In some specific embodiments, referring to fig. 2, the housing 12 includes a main housing 125 having a square shape, two sides of the main housing 125 are connected to a tapered cylinder 126, one end of the cylinder 126 having a larger diameter is connected to the main housing 125, and the air inlet 121 and the air outlet 122 are respectively disposed on the two cylinders 126; the first filter screen, the condenser and the second filter screen are arranged in the main box 125, the first filter screen is intercepted at the connection part between the main box 125 and one cylinder 126, and the second filter screen is intercepted at the connection part between the main box 125 and the other cylinder 126; the bottom of the main tank 125 is provided with a waste storage tank 127, and the waste discharge port 123 is arranged at the bottom of the waste storage tank 127. Thus, the conical structure of the cylinder 126 can enable the water vapor and oily impurities to flow into the main tank 125 along the inner wall of the cylinder 126 and drop into the waste storage tank 127 when the water vapor and oily impurities are condensed into liquid in the cylinder 126; the waste storage box 127 is used for providing enough storage space for impurities and waste, and avoiding the need of frequent maintenance and cleaning.

Further preferably, referring to fig. 1 or 2, the waste bin 127 is provided with a viewing window 128. Thus, the liquid level in the waste storage tank 127 can be observed through the observation window 128, so that impurities and waste can be discharged in time.

Referring to fig. 3, there is shown a crystallization drying system, including any one of the separators 1, further including a crystallization drying kettle 2 and a hot air device 3, wherein the hot air device 3 inputs hot air into the crystallization drying kettle 2 through an air inlet pipeline 4, and the crystallization drying kettle 2 returns the hot air to the hot air device 3 through an air return pipeline 5; the separator 1 is arranged on a return line 5. The separator 1 is used to separate impurities such as water, oil, dust and the like generated in the crystallization drying kettle 2 in the crystallization drying system, so that the impurities and hot air are prevented from flowing in the system at the same time, the production quality is prevented from being influenced, and the damage of oily impurities and particle impurities to the system modeling is also prevented. The air intake duct 4 and the air return duct 5 are not particularly limited to one duct, and may be a duct formed by one or more ducts or other accessories, so as to enable the hot air to flow along a predetermined path to a predetermined destination.

Preferably, referring to fig. 3, a cyclone dust collector 6 is further arranged on the return air pipeline 5 between the separator 1 and the crystallization reaction kettle; the dust removing mechanism of the cyclone dust remover 6 is that hot air is made to rotate, particles are separated from air flow by centrifugal force and are trapped on the wall of the cyclone dust remover, and then the particles fall down by gravity, and the hot air rises and is discharged; in this way, in the return air pipeline 5, the hot air firstly passes through the cyclone dust collector 6 to remove particles with larger granularity, so that on one hand, the dust removing effect is improved; on the other hand, too many particles are prevented from being accumulated in the separator 1, and the waste outlet 123 is prevented from being easily blocked due to too high coagulation degree of the oily impurities mixed with the particles.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
