[0022] Referring to Figures 1-7 The utility model provides a kind of technical scheme for solvent recovery equipment of microsphere production:

[0023] Referring to Figure 1 A kind of solvent recovery equipment for microsphere production, including evaporating bucket 1, referring to Figure 5 As shown in figure 1, evaporating bucket 1 is set as a cylindrical bucket with open top, referring to Figure 1 And Figure 7 As shown in figure 1, the bottom of evaporating bucket 1 is provided with annular recess 104 towards its side wall, and heating coil 103 is arranged in the inside of annular recess 104, which generates heat after being electrified and is transferred to the side wall of evaporating bucket 1, thereby heating the waste solvent loaded in evaporating bucket 1 to evaporate the waste solvent, referring to Figure 3 As shown in figure 1, the outer side wall of evaporating bucket 1 is provided with heat insulation sleeve plate 101, wherein heat insulation sleeve plate 101 is provided in tubular shape and is attached to the outer side wall of evaporating bucket 1 to prevent the heat of the outer side wall of evaporating bucket 1 from spreading outward, and a plurality of struts 4 are fixedly connected to the top of evaporating bucket 1 at equal distances around the central axis of evaporating bucket 1, in an alternative embodiment, six struts 4 are provided, and the top of struts 4 is detachably connected to top cover 201, the bottom edge of top cover 201 is fixedly connected to side ring body 2, top cover 201 is fixedly connected to spiral glass tube 5, the top of spiral glass tube 5 extends out of the top of top cover 201, and heat insulation sleeve plate 101 is sleeved with receiving bucket 3 below the side ring body 2, and the inner diameter of receiving bucket 3 is greater than the outer diameter of side ring body 2.

[0024] Referring to Figures 4-6 As shown in figure 1, in an alternative embodiment, through holes 202 are formed in top cover 201 at the positions of struts 4, top screw rod 401 is fixedly connected to the top of struts 4, nut 402 is threadedly connected to top screw rod 401, the portion of top screw rod 401 passing through through holes 202 is threadedly connected with nut 402, the diameter of top screw rod 401 is smaller than the diameter of struts 4, and the inner diameter of through holes 202 is smaller than the diameter of struts 4, so that the staff can conveniently install or dismount top cover 201 by screwing nut 402, thereby improving the solvent recovery efficiency.

[0025] Need to be supplemented is that, referring to Figure 3As shown, the top surface of the top cover 201 is fixedly connected with a protective cavity 203 at the part of the spiral glass tube 5 extending out of the top surface of the top cover 201. Since the material of the spiral glass tube 5 is glass, it is easy to be broken or damaged. The protective cavity 203 can effectively protect the spiral glass tube 5 from being squeezed or impacted during use of the device, thereby improving the durability of the device. The bottom surface of the evaporation barrel 1 is provided with a pad 102. As shown in the figure, the pad 102 is provided with four pads around the central axis of the evaporation barrel 1 at equal distances. The pad 102 not only supports the device, but also leaves space for connecting the heating coil 103 to the external power supply, thereby facilitating the connection of the device to the external power supply. Figure 7 As shown in the figure, the pad 102 is provided with four pads around the central axis of the evaporation barrel 1 at equal distances. The pad 102 not only supports the device, but also leaves space for connecting the heating coil 103 to the external power supply, thereby facilitating the connection of the device to the external power supply. Figure 3 As shown in the figure, the bottom end of the spiral glass tube 5 extends out of the bottom of the side ring 2, thereby facilitating the connection of the spiral glass tube 5 to the external water supply pipe, so as to introduce cooling water into the spiral glass tube 5. The spiral glass tube 5 is located between the side ring 2 and the heat insulation sleeve plate 101, and is used to condense the solvent vapor between the side ring 2 and the heat insulation sleeve plate 101.

[0026] The working principle of the device will be described below. When the device is used, the waste solvent is poured into the evaporation barrel 1, and then the top cover 201 is placed on the top surface of the support rod 4. At this time, the top screw rod 401 passes through the through hole 202, and the top cover 201 is fixedly connected to the top surface of the support rod 4 by screwing the nut 402 into the top screw rod 401. The top end and the bottom end of the spiral glass tube 5 are connected to the external water pipe. Cooling water is introduced into the bottom end of the spiral glass tube 5. The external power supply of the heating coil 103 is connected. The heating coil 103 generates heat, which is transmitted to the waste solvent in the evaporation barrel 1 through the evaporation barrel 1, so that the waste solvent is boiled and evaporated into solvent vapor. The solvent vapor moves upward and downward through the gap between the side ring 2 and the heat insulation sleeve plate 101. Due to the cooling of the cooling water flowing upward in the spiral glass tube 5, the high-temperature solvent vapor condenses on the spiral glass tube 5 and drops downward, and finally falls into the receiving barrel 3. The user can use the solvent solution in the receiving barrel 3 for repeated application in the washing of microparticles.

[0027] The device is provided with the evaporation barrel 1, the heating coil 103 and the spiral glass tube 5, which work together to condense the waste solvent evaporated by the heating coil 103 by the spiral glass tube 5, thereby conveniently and quickly recycling the waste solvent. The structure is simple and can be placed near the microsphere washing operation. The device has a small footprint and can recycle the waste solvent in time and put it into repeated use, thereby reducing the amount of solvent used in the washing of microparticles, reducing the amount of waste solvent to be recycled, and further reducing the recycling cost. The recycling difficulty of the waste solvent is greatly reduced, the recycling efficiency of the solvent is improved, and the device is suitable for popularization and use in the field.

[0028] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
