DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-8 The utility model provides a technical solution: a tail gas safety recovery device in the waste lubricating oil regeneration process, including an evaporator 1, an tail gas pipe 2, a recovery and processing box 3, a sealing ring 4, a mounting mechanism 5, a mounting column 6, a movable bracket 7, a fixing rod 8, a fixing cap 9, an activated carbon filter purification net 10, a protrusion 11, a connecting plate 12, a movable pull rod 13, a spring 14, an auxiliary plate 15 and a fixing block 16.

[0032] When using the tail gas safety recovery device in the waste lubricating oil regeneration process, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the tail gas pipe 2 is fixedly installed at the upper right end of the evaporator 1. First, the recovery and treatment box 3 is plugged into the middle of the tail gas pipe 2, and a sealing ring 4 is provided between the recovery and treatment box 3 and the tail gas pipe 2. The sealing effect of the connection between the recovery and treatment box 3 and the tail gas pipe 2 is improved by the setting of the sealing ring 4 to prevent tail gas leakage. After the plugging is completed, the recovery and treatment box 3 is connected to the tail gas pipe 2. Figure 5 and Figure 6 As shown, a mounting mechanism 5 is provided at an equal angle on the outside of the tail pipe 2, and the mounting mechanism 5 includes a mounting column 6 fixedly connected to the left side of the recovery and treatment box 3, a movable bracket 7 rotatably connected to the edge of the tail pipe 2, a movable bracket 7 for connection, and a fixing rod 8 with a locking function;

[0033] By rotating the movable bracket 7, the movable bracket 7 rotates on the side of the exhaust pipe 2. At this time, the movable bracket 7 is connected with the mounting column 6 by a slot, which is convenient for limiting the mounting column 6 and the exhaust pipe 2. Then, the fixing rod 8 is inserted into the side of the movable bracket 7 away from the exhaust pipe 2. Then, the fixing cap 9 threadedly connected to the outer surface of the fixing rod 8 is rotated so that the fixing cap 9 and the movable bracket 7 are fitted together, which is convenient for limiting the movable bracket 7 and the mounting column 6 to prevent the movable bracket 7 from loosening from the mounting column 6, thereby facilitating the limiting of the recovery and treatment box 3 and the exhaust pipe 2, and fixing the recovery and treatment box 3 at the corresponding position on the evaporator 1.

[0034] After the installation is completed, when the exhaust gas generated during the evaporation of the waste lubricating oil inside the evaporator 1 is discharged from the recovery and treatment box 3 through the exhaust pipe 2, and the activated carbon filter purification net 10 is installed inside the recovery and treatment box 3, the activated carbon filter purification net 10 can filter and purify the generated exhaust gas before discharging it to the outside, preventing direct external discharge from causing serious pollution to the environment, and after the treatment is completed, such as Figure 1 and Figure 8 As shown, by pulling the movable pull rod 13, the movable pull rod 13 slides with the connecting plate 12, and the movable pull rod 13 drives the auxiliary plate 15 to move in the connecting plate 12. At this time, the auxiliary plate 15 squeezes the spring 14, causing the spring 14 to undergo elastic deformation, and the spring 14 drives the auxiliary plate 15 to move, so that the auxiliary plate 15 is disengaged from the protrusion 11, and the auxiliary plate 15 is disengaged from the activated carbon filter purification net 10, thereby releasing the limit between the activated carbon filter purification net 10 and the recycling and processing box 3, and then pulling the activated carbon filter purification net 10 to the front side, and pulling the activated carbon filter purification net 10 out of the recycling and processing box 3, thereby facilitating the disassembly and cleaning of the activated carbon filter purification net 10 to prevent the activated carbon filter purification net 10 from being blocked during long-term use.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
