Description

Technical Field

[0001] This utility model relates to the technical field of filtration equipment, specifically a high-efficiency and precision oil-absorbing filter bag installation mechanism. Background Technology

[0002] Bag filters are a type of high-efficiency filtration equipment commonly used for filtering gases and liquids. Their working principle is based on the fact that liquid enters through the inlet, is filtered by the filter bag, and flows out through the outlet, while impurities are intercepted by the filter bag. They can effectively filter suspended solids, dirt, and sediments in water, including oil, ensuring water cleanliness. In addition, the filter bags of bag filters can be replaced, allowing the equipment to continue to be used.

[0003] Currently, existing bag filters typically use several sets of bolts to lock the filter bags in place. This means that replacing the filter bags requires tightening and loosening these bolts, and since bag filters typically have multiple filter bags, this method results in lengthy replacement times and reduced operational efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency and precision oil suction filter bag installation mechanism to solve the problem mentioned in the background art that the installation of filter bags in existing bag filters usually involves locking the filter bags with several sets of bolts, which leads to a long time required to replace the filter bags.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency precision oil suction filter bag installation mechanism, including an installation plate.

[0006] The bottom of the mounting plate is fixed with a feed pipe, and the outside of the feed pipe is fitted with an internal thread sleeve. The bottom of the feed pipe is fixed with an installation pipe, and the outside of the installation pipe is fitted with a filter bag. The top of the filter bag is fixed with a filter bag mounting ring.

[0007] A notch is provided on the lower outer side of the feed pipe, and an L-shaped limiting block is provided in the notch. A wedge block is fixed on the top of the L-shaped limiting block, and the bottom of the L-shaped limiting block is located below the filter bag mounting ring.

[0008] A reset component is also provided in the notch.

[0009] Preferably, the feed pipe has a threaded line on its outer side, and the internal threaded sleeve is threadedly connected to the feed pipe through the threaded line.

[0010] Preferably, a magnetic ring is fixed at the bottom of the feed pipe.

[0011] In the above technical solution, the magnetic ring can adsorb the filter bag mounting ring, which facilitates installation.

[0012] Preferably, a rubber pad is fixed to the side of the L-shaped limiting block, and the rubber pad is in contact with the filter bag.

[0013] In the above technical solution, when several sets of L-shaped limiting blocks move to the bottom of the filter bag mounting ring and lock them, the rubber pads on the side of the L-shaped limiting blocks will squeeze the side of the filter bag, so that the side of the filter bag can fit tightly against the mounting tube, which helps to improve the firmness of the filter bag after installation.

[0014] Preferably, the reset assembly includes a T-shaped rod, which is fixed in the notch and slides through the L-shaped limiting block. A spring is sleeved on the T-shaped rod and connected to the L-shaped limiting block.

[0015] In the above technical solution, when the L-shaped limiting block moves laterally, it slides on the T-shaped rod. The T-shaped rod can guide the lateral movement of the L-shaped limiting block. When the internal threaded sleeve separates from the wedge block, the spring will drive the L-shaped limiting block to move away from the central axis of the mounting tube, so as to drive the L-shaped limiting block and the wedge block to reset.

[0016] Preferably, a U-shaped support frame is fixed to the bottom outer side of the internal threaded sleeve.

[0017] In the above technical solution, the U-shaped support frame can support the bottom of the filter bag, preventing the filter bag from deforming or tearing due to excessive pressure.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this high-efficiency and precision oil-absorbing filter bag installation mechanism,

[0019] (1) When in use, the filter bag can be placed on the outside of the installation tube, so that the top filter bag installation ring is attached to the bottom of the feed tube. Then, rotate the inner thread sleeve to make it descend outside the feed tube. The inner thread sleeve will slowly squeeze several sets of wedge blocks and drive several sets of wedge blocks and L-shaped limit blocks to approach each other. In this way, the L-shaped limit block can be moved to the bottom of the filter bag installation ring to lock it. Compared with the prior art, this technical solution only needs to rotate the inner thread sleeve to lock multiple positions of the filter bag installation ring. It is convenient to disassemble and assemble, effectively shortens the disassembly and replacement time, and improves the convenience during use.

[0020] (2) After the filter bag is installed, the U-shaped support frame can support the bottom of the filter bag. Since the filter bag will be subjected to a certain pressure of water flow when filtering liquid, this method can reduce the pressure at the bottom of the filter bag and prevent the filter bag from deforming or tearing due to excessive pressure, which helps to improve the service life of the filter bag.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a high-efficiency and precision oil-absorbing filter bag installation mechanism, such as... Figure 1 , Figure 2 and Figure 3 As shown, a feed pipe 2 is fixed to the bottom of the mounting plate 1, and an internal threaded sleeve 4 is fitted on the outside of the feed pipe 2. An mounting pipe 5 is fixed to the bottom of the feed pipe 2, and a filter bag 6 is fitted on the outside of the mounting pipe 5. A filter bag mounting ring 7 is fixed to the top of the filter bag 6.

[0027] A notch 9 is provided on the lower outer side of the feed pipe 2, and an L-shaped limiting block 10 is provided in the notch 9. A wedge block 12 is fixed on the top of the L-shaped limiting block 10, and the bottom of the L-shaped limiting block 10 is located below the filter bag mounting ring 7.

[0028] A reset component 13 is also provided in the notch 9.

[0029] like Figure 1 As shown, a threaded wire 3 is provided on the outside of the feed pipe 2, and the internal threaded sleeve 4 is threadedly connected to the feed pipe 2 through the threaded wire 3.

[0030] like Figure 2 and Figure 3 As shown, a magnetic ring 8 is fixed at the bottom of the feed pipe 2.

[0031] A rubber pad 11 is fixed to the side of the L-shaped limiting block 10, and the rubber pad 11 is in contact with the filter bag 6.

[0032] like Figure 2 and Figure 3 As shown, the reset assembly 13 includes a T-shaped rod 1301, which is fixed in the notch 9 and slides through the L-shaped limiting block 10. A spring 1302 is sleeved on the T-shaped rod 1301 and is connected to the L-shaped limiting block 10.

[0033] like Figure 1 As shown, a U-shaped support frame 14 is fixed to the bottom outer side of the internal threaded sleeve 4.

[0034] Working principle: When installing the filter bag 6, first, the filter bag 6 is placed on the outside of the installation tube 5, and the filter bag installation ring 7 is lifted upward. Then, the magnetic ring 8 will attract the filter bag installation ring 7. Then, the internal threaded sleeve 4 is rotated to move downward outside the feed tube 2. As the internal threaded sleeve 4 descends, the bottom of its inner wall will push the wedge block 12 located in the notch 9, and will drive several sets of wedge blocks 12 and L-shaped limiting blocks 10 to move closer to each other, so that the L-shaped limiting blocks 10 move below the filter bag installation ring 7 and lock it. At the same time, the rubber pad 11 on the side of the L-shaped limiting block 10 will squeeze the side of the filter bag 6. This allows the side of the filter bag 6 to fit tightly against the mounting tube 5, thus completing the installation of the filter bag 6. When it is necessary to disassemble the filter bag 6, rotate the inner threaded sleeve 4 to move it downward and upward outside the feed tube 2. As the inner threaded sleeve 4 moves upward, it will separate from the wedge block 12. At this time, the spring 1302 on the T-shaped rod 1301 will drive the L-shaped limiting block 10 to move away from the central axis of the mounting tube 5, so that the L-shaped limiting block 10 moves out from under the filter bag mounting ring 7, and at the same time drives the L-shaped limiting block 10 and the wedge block 12 to reset, thus completing the disassembly of the filter bag 6.

[0035] This completes the entire operation, and anything not described in detail in this specification is prior art known to those skilled in the art.
