Description

Technical Field

[0001] The utility model belongs to the technical field of waste lubricating oil regeneration, and in particular relates to a pretreatment storage tank for waste lubricating oil regeneration. Background Art

[0002] Before the waste lubricating oil is regenerated, a pretreatment tank is required to filter the waste lubricating oil.

[0003] The existing pretreatment storage tank includes a tank body and a filter placed on the top of the tank. The waste lubricating oil is poured from the top of the tank body onto the filter, and the filtered lubricating oil is stored through the tank body. However, impurities in the waste lubricating oil will cover the filter, causing the filter to be blocked. The filter needs to be cleaned or repaired regularly. At the same time, the filter is impacted by the waste lubricating oil for a long time, causing the filter holes on the filter to increase, thereby reducing the filtering effect of the equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a pretreatment storage tank for waste lubricating oil regeneration, so as to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0019] 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.

[0020] refer to Figure 1-2As shown, the utility model provides a pretreatment storage tank for waste lubricating oil regeneration, comprising: a tank body 3, a feeding mechanism for feeding waste lubricating oil is provided at the bottom of the tank body 3, a drainage mechanism and a filtering mechanism are provided in sequence from top to bottom inside the tank body 3, the filtering mechanism comprises a filter screen 12 and a floating object 11, the floating object 11 is arranged at the edge position of the filter screen 12, and the edge position of the floating object 11 is attached to the inner wall of the tank body 3, the floating object 11 is used to float the filter screen 12 on the liquid surface of the waste lubricating oil, the filter screen 12 is a funnel-shaped structure, and the bottom end of the funnel-shaped structure extends below the liquid surface of the waste lubricating oil, and one end of the drainage mechanism extends into the funnel structure of the filter screen 12.

[0021] As described above, when using the tank body 3, the feeding mechanism, the filtering mechanism and the drainage mechanism provided by the utility model, the waste lubricating oil can be easily introduced from the bottom of the tank body 3 through the feeding mechanism. When the waste lubricating oil rises in the tank body 3, the filter screen 12 rises with the liquid level through the floating object 11. Since the bottom of the filter screen 12 is funnel-shaped, the end of the drainage mechanism is above the filter screen 12 and below the liquid level of the filtered lubricating oil, thereby discharging the filtered lubricating oil outward through the drainage mechanism.

[0022] Further, in order to facilitate the placement of waste lubricating oil into the tank 3, refer to Figure 1-2 As shown, the feeding mechanism includes a liquid inlet hopper 5 and a liquid inlet pipe 4 which are connected and installed in sequence. The liquid inlet hopper 5 is arranged at the top of one side of the tank body 3, and the end of the liquid inlet pipe 4 which is away from the liquid inlet hopper 5 is connected and arranged at one side of the bottom of the tank body 3. The liquid inlet hopper 5 is convenient for adding waste lubricating oil into the liquid inlet pipe 4, and the waste lubricating oil is convenient for being introduced into the tank body 3 from the bottom of the tank body 3 and below the filter screen 12 through the liquid inlet pipe 4.

[0023] Further, in order to prevent the waste lubricating oil from being directly above the filter screen 12, refer to Figure 2-3 As shown, two stop blocks 15 for supporting the floating object 11 are symmetrically arranged on the inner wall of the tank body 3, and the liquid inlet pipe 4 is arranged below one of the stop blocks 15. When the waste lubricating oil in the tank body 3 is insufficient to provide buoyancy to the floating object 11, the stop blocks 15 are used to limit the height of the floating object 11, so as to prevent the connection between the liquid inlet pipe 4 and the tank body 3 from being above the floating object 11, thereby preventing the waste lubricating oil from being directly above the filter screen 12 without being filtered.

[0024] In the present utility model, combined with Figure 1-2As shown, the drainage mechanism of this embodiment includes a liquid outlet joint 8 and a liquid inlet joint 14. A crossbeam 10 connected to the floating object 11 is provided above the filter screen 12. The liquid inlet joint 14 is arranged on the crossbeam 10, and one end of the liquid inlet joint 14 extends to the bottom of the funnel-shaped structure of the filter screen 12. A connected mounting frame 7 is also installed above the tank body 3. The liquid outlet joint 8 is arranged on the mounting frame 7, and a hose 9 is connected between the liquid inlet joint 14 and the liquid outlet joint 8.

[0025] As mentioned above, when using the liquid discharge mechanism provided by the utility model, the hose 9 in the liquid discharge mechanism provides a soft connection for the liquid inlet connector 14 and the liquid outlet connector 8, and the hose 9 avoids interference with the lifting and lowering of the filter screen 12.

[0026] Further, in order to prevent the loose hose 9 from falling onto the filter screen 12, refer to Figure 1-2 As shown, an elastic rope 6 elastically connected to the crossbeam 10 is also installed on the mounting frame 7, and the hose 9 is at least partially connected to the elastic rope 6. The elastic force of the elastic rope 6 is less than the gravity of the filter screen 12. When the filter screen 12 is lifted by the floating object 11, the elastic rope 6 contracts, thereby driving the connected hose 9 to lift up, preventing the hose 9 from loosening and falling onto the filter screen 12.

[0027] In the present utility model, combined with Figure 1-2 As shown, a movable trolley 1 is also installed at the bottom of the tank body 3 of this embodiment, a mounting seat 2 for positioning the tank body 3 is provided on the top of the trolley 1, and a limiting groove 13 for accommodating the bottom end of the tank body 3 is opened on the top of the mounting seat 2.

[0028] As described above, when the trolley 1 provided by the utility model is used, the tank body 3 can be easily transported by the trolley 1 , and the limiting groove 13 on the mounting seat 2 can prevent the tank body 3 from being displaced on the trolley 1 .

[0029] 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.
