DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a hot bath oil filtering device proposed by the utility model comprises a base 7, a filtering station is arranged above the base 7, and the characteristic is that the filtering station comprises a support frame 2 fixedly mounted on the base 7, a filtering assembly 3 is arranged directly below the support frame 2, an oil inlet pipe 1 for supplying oil to the filtering assembly 3 is arranged on the support frame 2, a pressurizing device 8 is arranged between the filtering assembly 3 and the support frame 2, the oil is pressurized to increase the penetration speed of the oil in the filtering assembly 3, an oil outlet valve 32 is arranged at the bottom of the filtering assembly 3, an oil collecting tank 701 is arranged at the lower end of the base 7 located at the oil outlet valve 32, an oil outlet pipe 6 is arranged at the side end of the base 7, and the oil outlet pipe 6 is connected with the oil collecting tank 701 for discharging the filtered oil;

[0024] Three filtering stations are equidistantly arranged on the base 7 to filter the hot bath oil at the same time.

[0025] Furthermore, the side end of the support frame 2 is provided with an oil outlet 21 connected to the oil inlet pipe 1, and the side end of the filter assembly 3 is provided with an oil inlet valve 31. The oil outlet 21 is connected to the oil inlet valve 31 through a circulation pipe 4 to introduce the oil to be filtered into the filter assembly 3.

[0026] Furthermore, the filter assembly 3 includes multiple layers of filter plates, and the multiple layers of filter plates are sealed and stacked in connection.

[0027] Furthermore, the filter plate is filled with a filter element for filtering impurities in the oil, and the filter element may be activated carbon with strong adsorption.

[0028] Furthermore, a filter screen 5 is provided between two adjacent filter plates to further capture and filter fine impurities to ensure the cleanliness of the oil.

[0029] Furthermore, the pressurizing device 8 includes a pressurizing pump and a seal 81. The top end of the pressurizing pump is fixed on the support frame 2, and the bottom end is sealed and fixed to the top of the filter assembly 3 through the seal 81, and is connected to the inside of the filter assembly 3 for pressurizing the oil.

[0030] Furthermore, the pressurizing device 8 is an adjustable air pressure pump, which is used to pump gas into the filter component 3 for pressurization, thereby adjusting the penetration speed of the oil in the filter component 3.

[0031] The working principle of the hot bath oil filtering device based on the first embodiment is as follows: when in use, the hot bath oil is introduced into the oil outlet 21 above the support frame 2 through the oil inlet pipe 1, and is connected to the oil inlet valve 31 at the side end of the filter component 3 through the circulation pipe 4 through the oil outlet 21, so that the oil to be filtered is introduced into the filter component 3, and the oil enters the interior of the filter plate, so that the filter element of the filter plate is immersed in the oil, and the pressurizing device 8 at the top of the filter component 3 pumps gas into the interior of the filter component 3 for pressurization, so that the oil passes through the filter element and the filter screen 5 under the action of pressure and flows toward the bottom of the filter component 3. During the flow of the oil, impurities are adsorbed and attached to the filter element and the filter screen 5. The greater the pressure applied by the pressure pump, the faster the oil flow rate, thereby accelerating the filtering process. The filtered oil flows into the oil collecting tank 701 below the base 7 through the oil outlet valve 32 at the bottom of the filter component 3, and the oil in the oil collecting tank 701 is extracted and discharged through the oil outlet pipe 6 at the side end of the base 7 for recycling.
