Description

Technical Field

[0001] The utility model relates to the technical field of waste solvent treatment, in particular to a centralized treatment device for waste resin and waste coating solvents. Background Art

[0002] At present, a large amount of solid waste will remain in the water-based polyurethane resin wastewater. These solid wastes will absorb a large amount of heat during distillation, which will extend the working time and reduce the working efficiency.

[0003] In order to solve the above problems, there is a solution for a water-based polyurethane resin wastewater distillation recovery device (Announcement No. CN211445389U). A filter box is provided, and a filter screen is provided in the inner cavity of the filter box. The wastewater enters the filter box and is filtered. The solid waste will remain on the surface of the filter screen, and the waste liquid will flow into the distillation box along the connecting conduit. The waste liquid falls along the isolation plate. After being heated by the heater, the water vapor flows out along the outlet pipe, thereby reducing the solid waste in the distillation box.

[0004] However, the stirring rod and heater of the above solution are located inside the distillation box. Internal heating and stirring may cause more waste resin to remain inside the distillation box, especially around the stirring rod and heater. These residues are difficult to completely remove, affecting the distillation effect and subsequent use. The stirring rod and heater are located inside the distillation box, making cleaning more difficult. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example:

[0019] See also Figure 1-3The utility model provides a technical solution: a centralized treatment device for waste resin and waste paint solvent, comprising a heating box 1, a distillation tank 4 rotatably mounted in the heating box 1, and a support shaft 10 provided on the surface of the distillation tank 4, a cover 5 installed on the upper end of the distillation tank 4, the cover 5 having a tapered tube 6, a hose connected to the tapered tube 6, and discharging the distilled gas, the space in the heating box 1 allows the distillation tank 4 to swing, ensuring that the distillation tank 4 does not collide with the heating box 1;

[0020] A fixed plate 13 is fixed to the right side of the heating box 1. A slide rail 14 is installed on the surface of the fixed plate 13. A slider 16 is slidably connected to the slide rail 14. A rack 17 is connected to the slider 16. A gear 12 meshing with the rack 17 is installed on the surface of the support shaft 10. The rack 17 is located below the gear 12 and will not affect the removal of the distillation tank 4. It is more convenient to clean the distillation tank 4 and reduces the number of disassembly and assembly steps.

[0021] The motor 15 is mounted on the surface of the fixed plate 13, and the output end of the motor 15 is provided with an eccentric shaft 18. A transmission rod 19 is rotatably connected between the eccentric shaft 18 and the slider 16. The rotation of the eccentric shaft 18 drives the transmission rod 19 to move back and forth, and the transmission rod 19 drives the slider 16 to slide on the slide rail 14. The slider 16 drives the gear 12, the support shaft 10, and the distillation tank 4 to rotate forward and backward through the rack 17, thereby realizing the swing control of the distillation tank 4.

[0022] In this embodiment, if Figure 1 As shown, a support base 9 is installed on the side of the heating box 1, and the support shaft 10 is placed inside the support base 9 to support the distillation tank 4 without restricting the swing of the distillation tank 4.

[0023] In this embodiment, if Figure 1 As shown, a ball 11 is installed on the surface of the support seat 9, and the ball 11 is rollingly connected to the support seat 9 to prevent the distillation tank 4 from moving. The rotation of the ball 11 can also reduce the impact on the swing of the distillation tank 4.

[0024] In this embodiment, if Figure 1 As shown, a feeding pipe 7 is provided on the surface of the conical tube 6, and waste resin and waste paint solvent are poured into the distillation tank 4 using the feeding pipe 7. A hanging ear 8 is provided on the side of the distillation tank 4, and the hanging ear 8 and the distillation tank 4 can be lifted using a hook.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, a heating pipe 3 and a discharge valve 2 are installed at the lower part of the heating box 1. Water or oil is poured into the heating box 1, and the heating pipe 3 heats the water or oil to achieve heating of the distillation tank 4. If the water or oil needs to be replaced, the discharge valve 2 can be opened.

[0026] In this embodiment, if Figure 2 As shown, an elastic pad 21 is provided on the inner wall of the heating box 1. The elastic pad 21 is sleeved on the surface of the distillation tank 4. The elastic pad 21 can shield the heating box 1, reduce heat loss, and reduce the risk of burns.

[0027] In this embodiment, if Figure 3 As shown, the upper cover of the slider 16 is connected to a U-shaped seat 20 , and the transmission rod 19 is rotatably connected to the U-shaped seat 20 . Pins are inserted into the U-shaped seat 20 and the transmission rod 19 to maintain the rotational connection between the transmission rod 19 and the U-shaped seat 20 .

[0028] Specifically, when in use, the hose for discharging the distillation gas is connected to the conical tube 6, the waste resin or waste paint solvent is added to the distillation tank 4, and the heating box 1 heats the distillation tank 4. During the heating process, the motor 15 drives the eccentric shaft 18 to rotate. The rotation of the eccentric shaft 18 will drive the transmission rod 19 to move back and forth, and the transmission rod 19 drives the slider 16 to slide. The slide rail 14 ensures that the slider 16 can only slide in a straight line, thereby improving the swing stability of the distillation tank 4. The slider 16 drives the gear 12 to rotate through the rack 17, and the gear 12 drives the distillation tank 4 to rotate forward and backward through the support shaft 10. Since the support shaft 10 is located at the upper part of the distillation tank 4, the distillation tank 4 will swing in the heating box 1, ensuring that the waste resin or waste paint solvent is in a flowing state in the distillation tank 4, and the distillation efficiency is high. No components are installed in the distillation tank 4, and the distillation tank 4 can be directly taken out of the heating box 1, which is convenient for cleaning.
