Description

Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a cooling structure of a separator drum. Background Art

[0002] Separator is a mechanical equipment that uses centrifugal force to separate light phase and heavy phase materials. It is widely used in food, pharmaceutical, chemical, textile, machinery and other industrial sectors, such as oil-water residue separation of mineral oil, fuel oil, vegetable oil, animal fat, etc., antibiotic separation, clarification of beer, juice, varnish, bacterial culture fluid, dairy products, oils, etc., as well as concentration of latex and yeast, separation of difficult-to-separate emulsions, etc.

[0003] The separator includes a base, drive components, transmission components, a drum, and a feeding and discharging system. In the separation process of some materials, the temperature of the material is not allowed to rise during the separation process. For example, during the separation process of blood, the material should be kept in a temperature range of -7°C to 2°C for the separation process. However, during the high-speed rotation of the drum of the separator, it constantly rubs against the air and generates a lot of heat, which increases the temperature of the material and affects the characteristics of the separated material.

[0004] Chinese patent CN211099618U discloses a spiral cooling jacket device for a butterfly separator, wherein the cooling jacket device is arranged around the machine body, and circulating coolant is introduced into the cooling jacket device to cool the drum inside the machine body. This cooling device is arranged on the machine body, and has no direct contact with the drum and the material inside the drum. Therefore, it needs to exchange and transfer heat through the air between the machine body and the drum to cool the drum and the material in the air, and the cooling efficiency is low, and the cooling effect is not ideal.

DETAILED DESCRIPTION

[0024] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, the drum 2 of the utility model is fixed on the main shaft 1, and the main shaft 1 is connected to the driving mechanism through a transmission mechanism (not shown in the figure), and the driving mechanism drives the drum 2 to rotate at high speed through the main shaft 1. A pump wheel 3 is sleeved on the main shaft 1 and located below the drum 2. The pump wheel 3 and the main shaft 1 are clearance-matched and do not rotate with the main shaft 1. There is a certain distance between the pump wheel 3 and the drum 2 to prevent the pump wheel 3 from interfering with the rotation of the drum 2. A cooling sleeve 4 is provided on the inner side of the drum 2, and the cooling sleeve 4 is attached to the inner side of the drum 2. A refrigerant channel 5 is opened between the drum 2 and the cooling sleeve 4.

[0026] like Figure 1 As shown, the drum 2 is provided with a plurality of refrigerant delivery channels 21 and a plurality of refrigerant outlets 22 connected with the refrigerant channel 5, and the pump wheel 3 is provided with a plurality of refrigerant inlet channels 31. The inlet of the refrigerant inlet channel 31 is connected with a refrigerant supply device (not shown in the figure), and the outlet of the refrigerant inlet channel 31 is connected with the inlet of the refrigerant delivery channel 21. There is a distance between the outlet of the refrigerant inlet channel 31 and the inlet of the refrigerant delivery channel 21.

[0027] like Figures 1 to 3 As shown, the refrigerant delivery channel 21 of the drum 2 is opened at the bottom of the drum 2, including an inclined hole section 211 and a vertical hole section 212. The inclined hole section 211 is inclined downward from the inside to the outside to facilitate the suction and backward delivery of the refrigerant. The vertical hole section 212 connects the end of the inclined hole section 211 with the bottom of the refrigerant channel 5. Figure 2 As shown, a groove 23 is provided on the drum 2 corresponding to the entrance of the refrigerant delivery channel 21. The entrance of the refrigerant delivery channel 21 is provided at the bottom of the groove 23. The groove 23 constitutes a refrigerant collection groove. The refrigerant flows into the refrigerant delivery channel 21 from the collection groove, which is conducive to all the refrigerant sucked from the refrigerant entry channel 31 flowing into the refrigerant delivery channel 21, thereby avoiding the waste of refrigerant. The upper side of the groove 23 is an inclined surface 24, and the lower side is a horizontal surface 25. The outlet of the refrigerant entry channel 31 faces the upper part of the bottom of the groove 23 and the lower part of the inclined surface 24. The inclined surface 24 can guide the refrigerant into the refrigerant delivery channel 21, which is more conducive to the inhalation of the refrigerant.

[0028] like Figure 1As shown, the refrigerant inlet channel 31 of the pump wheel 3 includes a vertical section 311 and a horizontal section 312 . The vertical section 311 is connected to the refrigerant supply device, and the horizontal section 312 is connected to the refrigerant delivery channel 21 .

[0029] like Figures 1 to 3 As shown, the refrigerant channel 5 includes a bottom section 51 located at the bottom of the cooling spacer 4, a spiral section 52 and a top section 53 located at the periphery of the cooling spacer 4, the bottom section 51, the spiral section 52, and the top section 53 are connected in sequence, the bottom section 51 is connected to the refrigerant delivery channel 21 of the drum 2, the top section 53 is connected to the refrigerant outlet 22 of the drum 2, and the spiral section 52 is spirally wound on the outer peripheral surface of the cooling spacer 4. In this embodiment, a continuous groove body 41 is provided on the cooling spacer 4, and the channel formed by the continuous groove body 41 constitutes the refrigerant channel 5; in other embodiments, a continuous groove body 41 can also be provided on the drum 2 to form the refrigerant channel 5.

[0030] In this embodiment, the cooling jacket 4 is disposed on the inner side of the drum 2 . In other embodiments, the cooling jacket 4 may also be disposed on the outer side of the drum 2 .

[0031] When the utility model is actually used, the driving mechanism drives the drum 2 to rotate at high speed through the main shaft 1, and negative pressure is formed at the outlet of the refrigerant delivery channel 21 and the refrigerant inlet channel 31. The refrigerant of the refrigerant supply device is sucked into the refrigerant delivery channel 21 through the refrigerant inlet channel 31. Under the action of strong centrifugal force, the refrigerant enters the refrigerant channel 5, flows from bottom to top, and is then discharged from the refrigerant outlet 22. In the process of the refrigerant constantly entering and exiting the cycle, the heat generated by the high-speed rotation of the drum 2 is taken away, so that the temperature of the drum 2 is maintained within the range required by the process, so that the materials can be separated under the temperature environment required by the process, thereby ensuring the quality and performance of the materials.

[0032] The utility model arranges the cooling sleeve 4 on the drum 2, and the refrigerant in the refrigerant channel 5 between the cooling sleeve 4 and the drum 2 directly contacts the drum 2 for heat exchange, and performs contact cooling on the drum 2, which has higher cooling efficiency and better cooling effect.

[0033] The above description is an explanation of the utility model, not a limitation of the utility model. The utility model can be modified in any form without violating the spirit of the utility model.
