Description

Technical Field

[0001] This utility model belongs to the field of pulp and paper machinery technology, specifically relating to a static oil-water separation device for the lubrication system of a double-roll pulp washing machine bearing seat. Background Technology

[0002] The double-roller washer is a high-efficiency pulp washing equipment that integrates filtration and dewatering, displacement washing, and pressing dewatering. Due to prolonged contact with alkaline pulp and high-temperature steam, the existing sealing system of the double-roller washer bearing housing is prone to moisture / steam intrusion into the lubrication system (actual moisture intrusion can reach 8-15%), and fiber impurities adhering to the bearing interior can cause bearing damage. Utility Model Content

[0003] The purpose of this invention is to provide a static oil-water separation system for the bearing housing lubrication system of a double-roll washing machine, thereby solving the problems of water easily seeping into the lubrication system and fiber impurities adhering to the bearing interior, leading to bearing damage.

[0004] The technical solution adopted by this utility model is a static oil-water separation device for the lubrication system of a double-roll washing machine bearing seat, including an oil-water separator. The top of the oil-water separator is connected to the oil-water separator cover by a sealing bolt. An oil-water separator inlet interface is opened in the center of the oil-water separator cover. A filter element liner is detachably installed on the upper part of the oil-water separator. The filter element liner is connected to the oil-water separator inlet interface. A bearing seat is sealed and installed above the oil-water separator inlet interface. A drain and vent valve interface is opened at the bottom of the oil-water separator.

[0005] Preferably, the top of the inner wall of the oil-water separator is provided with an L-shaped filter element inner liner fixing groove, and the top edge of the filter element inner liner is provided with an overlapping plate matching the L-shaped filter element inner liner fixing groove. The filter element inner liner is overlapped on the L-shaped filter element inner liner fixing groove through the overlapping plate.

[0006] Preferably, the inner liner of the filter element is provided with a primary coarse filter screen, which is an 80-100 mesh stainless steel mesh.

[0007] Preferably, a secondary oleophilic-hydrophobic membrane with a pore size of 5-10 μm is provided between the primary coarse filter screen and the filter element inner liner, and is made of PTFE composite material.

[0008] Preferably, an observation port is provided on the side wall of the oil-water separator, and a transparent observation cap is provided on the observation port. The observation cap is connected to the side wall of the oil-water separator by fastening bolts.

[0009] Compared with existing technologies, the advantages of this invention are as follows: by installing an oil-water separator below the bearing housing, water vapor entering the bearing housing naturally settles based on the density difference between water (heavy) and oil (light), and water and air are periodically drained and vented, preventing water / vapor from entering the lubrication system and ensuring the controllability of the lubricating grease in the bearing housing. At the same time, a filter element is installed inside the oil-water separator to filter fibrous impurities, preventing them from adhering to the inside of the bearing and causing damage. This device does not require changes to the original lubrication pipeline layout during modification, saving installation space, ensuring the safe operation of the equipment, and extending the bearing life cycle.

[0011] Figure 2 This is a schematic diagram of the filter cartridge inner liner. Detailed Implementation

[0012] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0013] Example 1

[0014] like Figure 1-2 As shown, a static oil-water separation device for a bearing housing lubrication system of a double-roll washing machine includes an oil-water separator 4. The top of the oil-water separator 4 is connected to an oil-water separator cover 2 via sealing bolts 3. An oil-water separator inlet 1 is located in the center of the oil-water separator cover 2. A filter element liner 8 is detachably installed on the upper part of the oil-water separator 4, communicating with the oil-water separator inlet liner 8. A bearing housing (221MA121 or 221MA125 double-roll washing machine bearing housing) is sealed above the oil-water separator inlet liner 1. A drain and vent valve 9 is located at the bottom of the oil-water separator 4. Due to the density difference between water and oil, water vapor entering the bearing housing naturally settles and seeps into the oil-water separator 4 below, preventing moisture / vapor from entering the lubrication system and ensuring the controllability of the lubricating grease in the bearing housing. Simultaneously, water entering the oil-water separator, after passing through the filter element liner, is filtered to remove fibrous impurities, preventing them from adhering to the bearing interior and causing bearing damage.

[0015] Furthermore, the top of the inner wall of the oil-water separator 4 is provided with an L-shaped filter element inner liner fixing groove 10, and the top edge of the filter element inner liner 8 is provided with an overlapping plate 801 matching the L-shaped filter element inner liner fixing groove 10. The filter element inner liner 8 is overlapped on the L-shaped filter element inner liner fixing groove 10 through the overlapping plate 801, which facilitates disassembly, cleaning and replacement, and ensures the filtration effect.

[0016] The filter cartridge inner liner is equipped with a primary coarse filter 11, which is an 80-100 mesh stainless steel mesh used to intercept fibrous impurities. A secondary oleophilic and hydrophobic membrane 12 with a pore size of 5-10 μm is provided between the primary coarse filter 11 and the filter cartridge inner liner 8. It is made of PTFE composite material and is used to filter fine dust.

[0017] An observation port 6 is provided on the side wall of the oil-water separator 4. A transparent observation cover 5 is provided on the observation port 6. The observation cover 5 is connected to the side wall of the oil-water separator 4 by fastening bolts 7. The internal condition of the oil-water separator can be viewed through the observation port so that the drain and air vent valve can be opened to discharge water.

[0018] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from its design spirit and principles should fall within the protection scope defined by the claims of the present invention.
