[0019] The following is combined with Figure 1-6 The specific implementation methods of the utility model are further described in detail.

[0020] Embodiment 1, the technical solution is that when the utility model is in use, the two-stage filter provided can fully filter the hydraulic oil to remove the impurities therein, and the disassembly and installation of the two-stage filter device 2 are relatively convenient, which is convenient for maintenance, and the cold shortage device provided can efficiently cool the filtered hydraulic oil to facilitate the processing of the subsequent steps and improve the work efficiency. When the utility model is in use, the hydraulic oil to be recycled is first processed by the two-stage filter device 2, and then temporarily stored in the conical recovery cylinder 1, so that the cooling device 3 therein can quickly cool the filtered hydraulic oil, and the hydraulic oil after the cold shortage can be discharged through the discharge pipe 5 for the next step of processing. The water supply device 4 provided can provide cold water for the cooling device 3, so as to heat exchange and cool the hydraulic oil, and the cold water after heat exchange can enter the collection bucket 17 through the conduit 16 of the collection device, so as to reuse the cooling water. The support leg 7 provided is convenient for supporting the device. When the utility model is in use, the filter hole diameter of the secondary filter 26 in the two-stage filter device 2 is smaller than the diameter of the primary filter hole 21, so as to ensure the filtering quality.

[0021] Embodiment 2, on the basis of embodiment 1, when the present invention is used, the hydraulic oil with recycling treatment is passed from the upper end of the conical recycling cylinder 1 into the concave plate 20 of two-stage filtration, and the concave plate 20 is provided with a primary filter hole 21, which can filter the larger impurities in the hydraulic oil. The concave plate 20 is in a smooth concave shape, so that the hydraulic oil can pass through the concave plate 20 relatively concentratedly and fall to the secondary filter screen 26, and the secondary filter screen 26 can filter the smaller impurities in the hydraulic oil. The primary filter hole 21 of the concave plate 20 cooperates with the secondary filter screen 26 to filter the hydraulic oil relatively well, ensuring the filtering quality. The concave plate 20 is movably mounted on the support ring 18 through the large connecting ring 19, and the concave plate 20 can be conveniently disassembled, cleaned and maintained through the handle 22. The small connecting ring 25 of the secondary filter screen 26 is movably plugged into the positioning column 27 of the support ring 24 through the positioning hole 28 for limiting, which is also convenient for disassembly and cleaning. The support ring 24 is installed below the support ring 18 through the support rod 23.

[0022] Embodiment 3, on the basis of embodiment 2, the utility model has cold water accumulated in the water supply tank 11 when in use. When the cooling device 3 is in use, the water supply pump 13 of the water supply device 4 is started and the water supply valve 15 is opened. Under the action of the water supply pump 13, the cold water in the water supply tank 11 enters the upper multi-way joint 8 through the front water supply pipe 12 and the rear water supply pipe 14 at a relatively stable pressure and flow rate, and then enters each copper tube 9. The copper tube 9 has good thermal conductivity and is provided with multiple groups, so that the hydraulic oil in the conical recovery cylinder 1 can be efficiently heat exchanged. After heat exchange, the cold water enters the lower multi-way joint 10 through the copper tube 9, and enters the conduit 16 of the collection device from the lower multi-way joint 10, and enters the collection bucket 17 from the conduit 16 for collection, thereby avoiding the waste of water resources. The cooled hydraulic oil can be discharged through the discharge pipe 5 by opening the discharge valve 6.
