Description

Technical Field

[0001] The utility model belongs to the field of filtering equipment, in particular to a pulse-type high-efficiency hydraulic oil cleaning filter. Background Art

[0002] Hydraulic oil cleaning filters are devices used to remove impurities and contaminants from hydraulic fluid. Current hydraulic oil cleaning filters have several drawbacks. First, most hydraulic oil cleaning filters lack a pulse mechanism, resulting in relatively low filtration efficiency. This lack of pulse action allows impurities to accumulate on the filter element, accelerating clogging and reducing filtration effectiveness. This is primarily due to the fact that traditional filters rely solely on the natural flow of hydraulic fluid for filtration, failing to effectively remove impurities that stubbornly adhere to the filter element. Conventional solutions involve regularly replacing or cleaning the filter element. However, this approach has drawbacks. Frequent filter element replacement increases costs and can cause temporary downtime in the hydraulic system during replacement, impacting production efficiency. While cleaning the filter element can extend its lifespan to a certain extent, the cleaning process is cumbersome, requires specialized personnel, and is difficult to guarantee. Therefore, a new structure is needed to address these technical issues. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 2 The utility model provides a technical solution: a pulse type high efficiency hydraulic oil cleaning filter, comprising: a filter assembly and a pulse assembly, the pulse assembly is installed on the upper surface of the filter assembly, the filter assembly comprises: a mounting frame 100, a mounting frame 2 120, an oil inlet pipe 110 and an oil outlet pipe 130, a filter element group 150 is installed between the mounting frame 100 and the mounting frame 2 120, a support leg 140 is installed on the lower surface of the mounting frame 2 120, the oil inlet pipe 110 passes through the mounting frame 100, and the oil outlet pipe 130 passes through the mounting frame 2 1 20. The outer surfaces of the mounting frame 1 100, the mounting frame 2 120 and the filter element group 150 are sealed with a shell 200 on the upper side, and the outer surfaces of the mounting frame 100, the mounting frame 2 120 and the filter element group 150 are sealed with a bottom shell 230 on the lower side. The pulse assembly includes: a pulse generator 210 and a pressure flow sensor 220. The pulse generator 210 is installed on the upper surface of the shell 200, the pressure flow sensor 220 is installed on the outer surface of the shell 200, and the discharge valve 240 is installed on the lower surface of the bottom shell 230.

[0019] See also Figure 1 、 Figure 2 As a first embodiment of the present invention, the height of the first mounting frame 100 matches the height of the second mounting frame 120 and the support leg 140. A filter element group 150 is installed between the front surface of the first mounting frame 100 and the rear surface of the second mounting frame 120. The oil outlet end of the oil inlet pipe 110 is disposed inside the filter element group 150, and the oil inlet end of the oil outlet pipe 130 is disposed inside the filter element group 150.

[0020] The inner diameters of the oil inlet pipe 110 and the oil outlet pipe 130 match, and the central axes of the oil inlet pipe 110 and the oil outlet pipe 130 are collinear. The housing 200 is integrally and sealedly mounted on the top, left, and right surfaces of the mounting frame 100, the mounting frame 2 120, and the filter element assembly 150. The interior of the housing 200 abuts against the top, left, and right surfaces of the filter element assembly 150.

[0021] When in use, the user first fills the hydraulic oil that needs to be cleaned into the oil inlet pipe 110 under high pressure, so that the hydraulic oil enters the filter element group 150 through the oil inlet pipe 110 for filtration. When the hydraulic oil gradually passes through the filter element group 150, it will be filtered by the filter element group 150 (the filter element group 150 is a prior art, and its specific structure only needs to meet the requirements of filtering the hydraulic oil, which will not be described in detail here). The hydraulic oil after filtering will be discharged through the oil outlet pipe 130 and then continue to be used. Since the installation frame 100 and the installation frame 2 120 provide a stable support structure for the filter medium, ensuring that the filter medium can fully play its role, at the same time, the colinear design of the oil inlet pipe 110 and the oil outlet pipe 130 can ensure the smooth flow of the hydraulic oil in the filter, the oil inlet pipe 110 introduces the hydraulic oil to be filtered into the filter, and the oil outlet pipe 130 outputs the filtered clean oil. This directional flow can make the oil fully contact with the filter medium, thereby improving the filtration efficiency.

[0022] See also Figure 1 、 Figure 2 As a second embodiment of the present invention, a bottom shell 230 is integrally and sealedly mounted on the lower, left, and right surfaces of the mounting frame 100, the mounting frame 2 120, and the filter element assembly 150. The bottom shell 230 has an accommodating cavity disposed therein. A discharge valve 240 is mounted at the lower center of the outer surface of the bottom shell 230. The interior of the bottom shell 230 communicates with the interior of the outer shell 200.

[0023] The bottom of the bottom shell 230 is designed to be conical. A pressure flow sensor 220 is installed at the center of the outer surface of the shell 200. The detection end of the pressure flow sensor 220 is set inside the shell 200.

[0024] The space between the housing 200, the bottom housing 230, the first mounting frame 100, and the second mounting frame 120 is combined to form a storage cavity. The filter element group 150 is disposed inside the storage cavity through the first mounting frame 100 and the second mounting frame 120. The generating end of the pulse generator 210 is disposed inside the housing 200.

[0025] During use, since a receiving cavity is provided inside the bottom shell 230, when the hydraulic oil is filtered through the operating steps of the first embodiment, a portion of the hydraulic oil will remain inside the receiving cavity of the bottom shell 230. If the filter element group 150 needs to be cleaned, the user can start the pulse generator 210 on the upper surface of the shell 200. At this time, the pulse generator 210 is started (the pulse generator 210 is a prior art, and its model can be selected from the existing market model. It only needs to meet the use of the device. Its specific working principle and structure are not described here), generating pulses to impact the filter element group 150, thereby separating the objects on the outer surface of the filter element group 150 from the filter element group 150. When the separation is completed, the objects will enter the receiving cavity of the bottom shell 230, thereby completing the collection. At this time, the user opens the discharge valve on the outer surface of the bottom shell 230. 240 can discharge the objects inside the bottom shell 230. When in use, the pulses generated by the pulse generator can impact and vibrate the filter element in the filter assembly, loosening and detaching the impurities attached to the filter element (the filter element group is the existing technology, and its specific structure will not be repeated here). When the impurities detach from the filter element group 150, they will float downward and fall into the interior of the accommodating cavity of the bottom shell 230 due to gravity, thereby completing the collection of impurities. In addition, because the left and right inner walls of the accommodating cavity inside the bottom shell 230 will block the impurities inside when the hydraulic oil moves, during the flow and filtration of the hydraulic oil, the impurities will be in the accommodating cavity inside the bottom shell 230 and will not return to the interior of the filter element group 150 due to the flowing hydraulic oil, preventing the filter element from being blocked, thereby significantly improving the filtration efficiency. Especially for some tiny particles and sticky impurities, the effect of the pulse is more obvious.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
