Hydraulic oil and iron filings filtering device for a piston pusher centrifuge

Abstract

This utility model discloses a hydraulic oil iron filings filtration device for a piston-feeding centrifuge. Its features include a guide plate and chip baffle mounted on a side rib, an iron filings bubble filter frame mounted on the side rib and above the guide plate and chip baffle, a filter screen on the iron filings bubble filter frame to eliminate air bubbles as the hydraulic oil passes through, and several magnetic strips on the iron filings bubble filter frame for filtering iron filings. Through the guide plate and magnetic strips, when iron filings travel with the hydraulic oil from the return oil zone through the oil cooling zone, the guide plate and chip baffle prevent the hydraulic oil from reaching the suction zone only through the iron filings bubble filter frame. As the hydraulic oil passes through the iron filings bubble filter frame, the iron filings are attracted by the magnetic strips on the frame, thus filtering the iron filings in the hydraulic oil. This prevents iron filings from re-entering the pressure cylinder with the hydraulic oil, which would aggravate wear on moving parts, leading to abnormal noise or complete damage to the piston assembly.

Description

Technical Field

[0001] This utility model relates to hydraulic oil filtration for centrifuges, specifically a hydraulic oil iron filings filtration device for a piston pusher centrifuge. Background Technology

[0002] In a piston pusher centrifuge, hydraulic oil is pumped from the oil tank and fed into a high-speed rotating pressure cylinder. The hydraulic oil acts on the piston assembly with a reversing mechanism, which drives the pusher shaft to reciprocate, thus pushing the material. The hydraulic oil that has completed its function returns to the oil tank from the return oil area.

[0003] During this reciprocating motion, the surfaces that are in contact with each other and moving relative to each other are constantly rubbing against each other. The fine iron filings generated by the friction will return to the oil tank with the hydraulic oil, contaminating the hydraulic oil. If the iron filings re-enter the pressure cylinder with the hydraulic oil, it will aggravate the wear of the moving parts, leading to abnormal noise or complete damage to the piston assembly.

[0004] The hydraulic oil returns to the tank by flowing naturally downwards from a high place. When it returns to the tank and mixes with the hydraulic oil inside, air bubbles are generated. The air bubbles in the hydraulic oil can affect system performance and the life of components. For example, the oil pump may make abnormal noises; oil deterioration may affect the feeding frequency, etc.

[0005] Existing technologies, in order to solve the problem of iron filings, only fix magnets at the corners of the oil tank, without any structure to deal with air bubbles. Furthermore, the magnets are located in a non-flowing area of ​​the hydraulic oil, so the iron filings cannot be effectively attracted, resulting in a poor filtration effect, as shown in the attached diagram in the instruction manual. Figure 7 As shown. Therefore, a hydraulic oil iron filings filtration device for a piston-push centrifuge is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a hydraulic oil iron filings filtration device for a piston-pushing centrifuge to solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic oil iron filings filtration device for a piston pusher centrifuge, comprising an oil tank and side ribs installed inside the oil tank, wherein the oil tank is provided with an oil return zone, an oil cooling zone, and an oil pump suction zone; characterized in that it further includes a flow guide and chip baffle plate installed on the side rib, an iron filings bubble filter frame installed on the side rib and above the flow guide and chip baffle, a filter screen installed on the iron filings bubble filter frame to eliminate bubbles when hydraulic oil passes through, and several magnetic strips installed on the iron filings bubble filter frame for filtering iron filings.

[0008] A further preferred embodiment includes a magnetic strip mounting block disposed on the iron filings bubble filter frame for mounting magnetic strips, the magnetic strip mounting block having a magnetic strip mounting groove that defines the mounting position of the magnetic strips.

[0009] In a further preferred embodiment, the side rib plate is also provided with a hook, and the iron filings bubble filter rack is provided with a hanging rod that cooperates with the hook to install the iron filings bubble filter rack on the side rib plate.

[0010] A further preferred embodiment includes a magnetic stripe inspection window located on the fuel tank for easy observation of the magnetic stripe filtration, and a cover plate installed on the fuel tank to seal the magnetic stripe inspection window.

[0011] The beneficial effects of this utility model are as follows: By setting up the flow guide and chip baffle plate and magnetic strips, when the iron filings pass through the oil cooling zone from the return oil zone with the hydraulic oil, the hydraulic oil can only reach the oil suction zone through the iron filings bubble filter frame due to the blocking effect of the flow guide and chip baffle plate. When the hydraulic oil passes through the iron filings bubble filter frame, the iron filings are attracted by several magnetic strips set on the iron filings bubble filter frame, which plays a filtering role on the iron filings in the hydraulic oil, and prevents the iron filings from re-entering the pressure cylinder with the hydraulic oil, which would aggravate the wear of the moving parts, leading to abnormal noise or complete damage to the piston assembly.

[0012] By installing a filter plate on the iron filings bubble filter frame, when the hydraulic oil passes through the filter plate, the air bubbles in the hydraulic oil are destroyed by the mesh holes, thereby eliminating the air bubbles and preventing them from affecting system performance and component life.

Detailed Implementation

[0021] The hydraulic oil and iron filings filtration device for a piston pusher centrifuge according to this utility model will be further described below with reference to the accompanying drawings.

[0022] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] See Figures 1-6 As shown, a hydraulic oil iron filings filtration device for a piston pusher centrifuge includes an oil tank 1 and a side rib plate 2 installed in the oil tank 1 by welding or integral molding. The oil tank 1 is provided with an oil return zone 11, an oil cooling zone 12 and an oil pump suction zone 13. It is characterized by further including a flow guide and chip baffle plate 3 installed on the side rib plate 2 by bolts, an iron filings bubble filter frame 4 installed on the side rib plate 2 and above the flow guide and chip baffle plate 3, a filter screen 5 installed on the iron filings bubble filter frame 4 by screws, bolts or welding or any other fixing method to eliminate bubbles when hydraulic oil passes through, and a number of magnetic strips 6 provided on the iron filings bubble filter frame 4 for filtering iron filings.

[0025] With the setting of the flow guide and chip baffle 3 and the magnetic strips 6, when the iron filings pass through the oil cooling zone 12 from the return oil zone 11 with the hydraulic oil, the flow guide and chip baffle 3 blocks the hydraulic oil so that it can only pass through the iron filings bubble filter frame 4 to reach the oil suction zone. When the hydraulic oil passes through the iron filings bubble filter frame 4, the iron filings are attracted by several magnetic strips 6 set on the iron filings bubble filter frame 4, which plays a filtering role in the hydraulic oil and prevents the iron filings from re-entering the pressure cylinder with the hydraulic oil, which would aggravate the wear of the moving parts and cause abnormal noise or complete damage to the piston assembly.

[0026] By installing a filter plate 5 on the iron filings bubble filter frame 4, when the hydraulic oil passes through the filter plate 5, the air bubbles in the hydraulic oil are destroyed by the mesh holes, thereby eliminating the air bubbles and preventing them from affecting system performance and component life.

[0027] In one embodiment, a magnetic strip mounting block 61 is also provided on the iron filings bubble filter frame 4 for mounting the magnetic strip 6. The magnetic strip mounting block 61 is provided with a magnetic strip mounting groove 62 that defines the mounting position of the magnetic strip 6. The magnetic strip mounting block 61 can be mounted on the iron filings bubble filter frame 4 by any of the following methods: screw, bolt, or magnetic attraction. The magnetic strip mounting groove 62 defines the mounting position of the magnetic strip 6, and the magnetic strip 6 is mounted in the magnetic strip mounting groove 62 by magnetic attraction.

[0028] In one embodiment, the side rib plate 2 is also provided with a hook 21. The hook 21 can be fixedly installed on the side rib plate 2 by means of screws, bolts, welding, etc. The iron filings bubble filter frame 4 is provided with a hanging rod 41 that cooperates with the hook 21 to install the iron filings bubble filter frame 4 on the side rib plate 2. The iron filings bubble filter frame 4 is installed on the side rib plate 2 by hanging the hanging rod 41 on the hook 21. The setting of the hanging rod 41 and the hook 21 facilitates the installation and removal of the iron filings bubble filter frame 4 on the side rib plate 2.

[0029] In one embodiment, the system also includes a magnetic strip inspection window 14 disposed on the oil tank 1 for easy observation of the magnetic strip 6 filtration status, and a cover plate 15 mounted on the oil tank 1 by bolts or screws to seal the magnetic strip inspection window 14. The magnetic strip inspection window 14 allows operators to easily observe the adsorption of iron filings on the magnetic strip 6 inside the oil tank 1, thereby facilitating timely cleaning of the iron filings.

[0030] In use, when the hydraulic oil returns, the hydraulic oil containing iron filings flows to the return oil zone 11 and then to the oil cooling zone 12 for cooling. When the hydraulic oil flows to the oil pump suction zone 13, it is blocked by the guide and chip baffle plate 3 and can only flow to the oil pump suction zone 13 after passing through the filter plate 5. The iron filings in the hydraulic oil are attracted by the magnetic strip 6, and the air bubbles in the hydraulic oil are destroyed by the mesh when passing through the filter plate 5, thus eliminating the air bubbles in the hydraulic oil.

[0031] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
