[0057] In this embodiment, Figure 1 , Figure 3 or Figure 4 As shown, the vibrating member includes a rotating wheel 1601, which is fixedly sleeved on the coaxial outside of the first stirring rod 11. A support rod 1602 is fixed to the surface of the rotating wheel 1601. A pawl 1603 is rotatably sleeved on the outside of the support rod 1602. A leaf spring 1604 is installed at the bottom of the pawl 1603. The leaf spring 1604 is an elastic element that provides elasticity through its deformation, so that the pawl 1603 is always attached to the pawl groove 1606.

[0058] It also includes a first pulley 1605 and a second pulley 1608. A support shaft 16051 is fixed to the side wall of the cobalt chloride solution filter bin 1. The first pulley 1605 is rotatably sleeved on the outer shaft of the first pulley 1605. A ratchet groove 1606 is provided inside the first pulley 1605. The ratchet 1603 is meshed and connected with the ratchet groove 1606. The side wall of the cobalt chloride solution filter bin 1 is rotatably connected with a transmission shaft 1609. The second pulley 1608 is fixedly sleeved on the outer shaft of the transmission shaft 1609. A belt 1607 is wound around the outside of the first pulley 1605 and the second pulley 1608. The first pulley 1605 and the second pulley 1608 are transmitted through the belt 1607, so that the transmission shaft 1609 and the first stirring shaft rotate synchronously.

[0059] Cam 1610, cam 1610 is fixedly sleeved on the outer shaft of transmission shaft 1609, cam 1610 rotates in close contact with activated carbon filter 16, it should be noted that activated carbon filter 16 is a kind of high-efficiency filter element specially used for treating oil odor, and activated carbon is used as filter material, and its developed pore structure and strong adsorption force can effectively remove residual oil, harmful gases and impurity particles in cobalt chloride solution, and activated carbon filter 16 can be disassembled and cleaned. Since its disassembly is mostly done by bolts, it belongs to the prior art in this field and is not a major innovation, so it is briefly summarized here.

[0060] It should be noted that the specific models and specifications of the first motor 51 and the second motor 1102 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0061] The use method and advantages of the present invention: When the cobalt chloride solution circulating oil removal filter tank is working, the working process is as follows:

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, first, pour the cobalt chloride solution into the cobalt chloride solution filter bin 1 and add the oil-liquid separator, start the second motor 1102 to drive the first stirring rod 11 to rotate clockwise, and when the first stirring rod 11 rotates, the driving gear 1201 outside it rotates immediately and meshes with the driven gear 1202, and the driven gear 1202 is driven by the force to drive the second stirring rod 12 to rotate, so that the first stirring rod 11 and the second stirring rod 12 rotate to mix the oil-liquid separator and the cobalt chloride solution evenly, and at the same time, when the first stirring rod 11 rotates clockwise, its external rotating wheel 1601 also rotates synchronously, and when rotating, the ratchet 1603 uses the elastic properties of the leaf spring 1604 to make the ratchet 1603 elastically slide into the ratchet groove 1606 one by one without being hindered.

[0063] After the mixing is completed, the oil floats on the surface, and the manual rotating screw 64 disengages from the slide seat 6. The manual rotating rocker 63 drives the support shaft 61 to rotate. When the support shaft 61 rotates, the gear on the outside thereof rotates immediately and meshes with the toothed plate 8. The toothed plate 8 is forced to rise and fall. At the same time, the recess 81 inside thereof slides along the limiting column 82 and squeezes the spring 15. When the toothed plate 8 drives the oil removal filter element 9 to descend and be placed inside the cobalt chloride solution filter bin 1, the rotating screw 64 is embedded in the slide seat 6 to limit the rocker 63, so that the toothed plate 8 cannot slide. Then, the first motor 51 is started to drive the screw rod 52 to be placed in the mounting plate 4 for rotation. When the first screw rod 52 rotates, the slider 5 outside thereof is immediately placed in the groove of the mounting plate 4 and slides horizontally. The slide seat 6 on the end side of the slider 5 immediately drives the oil removal filter element 9 at the bottom to slide horizontally and then adsorbs the oil suspended on the surface, so as to realize automatic cleaning, avoid time-consuming and labor-intensive manual operation, and improve work efficiency.

[0064] After the processing is completed, the second motor 1102 is driven to drive in the reverse direction. When the second motor 1102 drives the first stirring rod 11 to rotate in the reverse direction, the rotating wheel 1601 outside it immediately drives the pawl 1603 to rotate counterclockwise. At this time, the pawl 1603 is stuck in the ratchet groove 1606. Through the cooperation between the pawl 1603 and the ratchet groove 1606, when the rotating wheel 1601 rotates counterclockwise, the pawl 1603 will drive the first pulley 1605 to rotate counterclockwise intermittently. When the first pulley 1605 rotates, it is driven by the belt 1607 to drive The second pulley 1608 rotates, and the transmission shaft 1609 in the middle of the second pulley 1608 is then placed on the side wall of the cobalt chloride solution filtering bin 1 and rotates. The cam 1610 on its outside hits the activated carbon filter 16 when rotating, and at the same time pulls the baffle 10 upward, and the cobalt chloride solution after the preliminary separation of the oil is discharged. When discharged, it flows through the activated carbon filter 16 for re-filtration treatment, so that the cobalt chloride solution is filtered twice, and then it can be filtered comprehensively, thereby improving the filtration quality of the cobalt chloride solution, and the filtered cobalt chloride solution is discharged through the drain pipe 2 for use.

Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
