Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and in particular relates to a filter bag type magnetic suction filter. Background Technology

[0002] Bag filters are widely used liquid filtration equipment. With their simple structure, convenient operation, large processing capacity, high cost-effectiveness and wide applicability, they have become an indispensable solid-liquid separation device in industrial, commercial and even some civilian fields. They use porous filter media (filter bags) to intercept suspended solid particles in liquids to achieve solid-liquid separation. However, existing filters typically require complete disassembly of the cylinder and end caps during disassembly, maintenance, or cleaning. This method cannot guarantee quick reassembly. Furthermore, under prolonged filtration, magnetic metallic impurities in the liquid can easily puncture the filter bags in existing bag filters. Therefore, we provide a magnetic bag filter to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a filter bag type magnetic suction filter. Through the cooperation of the rotating arm, handwheel and end cap, the end cap and cylinder can be quickly misaligned, which facilitates the cleaning of the inside of the cylinder. At the same time, the cooperation of the magnetic rod and the filter bag can increase the dirt holding capacity of the filter bag, extend the service life and reduce the possibility of metal impurities puncturing the filter bag.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a filter bag type magnetic filter, including a cylinder; a cap is provided on the upper end face of the cylinder, a perforated plate is bolted to the upper end of the cylinder, a filter bag is provided inside the cylinder below the perforated plate, the upper end of the filter bag passes through the perforated plate and communicates with the inside of the cap, a magnetic rod is fixed inside the filter bag, a rotating arm is rotatably connected to the frame on the outer wall of the cylinder, and a handwheel connected to the outer wall of the cap is spirally attached to the other end of the rotating arm.

[0005] The present invention is further configured such that the flange seat at the lower end of the end cap is connected to the flange seat at the upper end of the cylinder by bolts, and a vent pipe and a pressure gauge connected to the interior of the end cap are fixed on the outer wall of the end cap.

[0006] The present invention is further provided with a pad at the position between the end cap and the cylinder, and the end cap and the cylinder press the pad down.

[0007] The present invention is further configured such that the filter bag body is fixed to the lower end face of the tube sheet by the frame on the surface, and a sewage discharge pipe is provided at the lower position outside the cylinder body. The sewage discharge pipe passes through the side wall of the cylinder body and connects to the inside of the filter basket.

[0008] The present invention is further configured such that a liquid inlet pipe is fixed on the outer wall of the cylinder located below the tube sheet, and the liquid inlet pipe is connected to the interior of the end cap.

[0009] The present invention is further configured such that a nameplate is bolted to the outer side of the cylinder, and a drain pipe connected to the interior is fixed to the lower end face of the cylinder.

[0010] The present invention is further configured such that a leg-type support is fixed to the outer wall of the cylinder, and an electrostatic grounding plate is fixed to the side wall of the leg-type support.

[0011] This utility model has the following beneficial effects: Unscrew the flange seats on the end cap and the cylinder, and control the handwheel to move it spirally upward on the rotating arm. This handwheel will cause the end cap to move up and down, thereby opening the cylinder. Then control the rotating arm to rotate, which will cause the end cap and the cylinder to be misaligned, making it easier to open the inside of the cylinder and clean the magnetic rod. At the same time, the use of the rotating arm can make the end cap and the cylinder misaligned without completely disassembling the end cap, thus achieving quick assembly and disassembly of the end cap and the cylinder.

[0012] The magnetic rods inside the filter bag adsorb solid impurities containing magnetic metal particles from the liquid onto their surface, while the filter bag itself traps the remaining non-magnetic non-metallic particles inside. This method increases the filter bag's dirt-holding capacity, extends its service life, and reduces the likelihood of metal impurities puncturing the filter bag. Attached Figure Description

Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] Please see Figures 1 to 3 This utility model is a filter bag type magnetic suction filter. By using the rotating arm 4, handwheel 401 and end cap 3 together, the end cap 3 and cylinder 1 can be quickly misaligned, which facilitates cleaning of the inside of cylinder 1. At the same time, the magnetic rod 201 and the filter bag together can increase the dirt holding capacity of the filter bag, extend the service life, and reduce the possibility of metal impurities puncturing the filter bag.

[0020] Specifically, there is a cylindrical body 1; a head 3 is provided on the upper end face of the cylindrical body 1, and a tube sheet 6 is bolted to the upper end of the interior of the cylindrical body 1. A filter bag body 2 is provided inside the cylindrical body 1 below the tube sheet 6. The upper end of the filter bag body 2 passes through the tube sheet 6 and is connected to the interior of the head 3. A magnetic rod 201 is fixed inside the filter bag body 2. A rotating arm 4 is rotatably connected to the frame on the outer wall of the cylindrical body 1. The other end of the rotating arm 4 is screwed with a handwheel 401 connected to the outer wall of the head 3. The filter bag body 2 is fixed to the lower end face of the tube sheet 6 by the frame on the surface. A drain pipe 104 is provided at the lower part of the exterior of the cylindrical body 1. The drain pipe 104 passes through the side wall of the cylindrical body 1 and is connected to the interior of the filter basket 202. An inlet pipe 102 is fixed to the surface wall of the cylindrical body 1 below the tube sheet 6 and is connected to the interior of the head 3.

[0021] The operation process of this embodiment is as follows: With the above-mentioned structure, after the liquid flows from the inside of the end cap 3 into the filter bag body 2, the magnetic rod 201 in the filter bag body 2 adsorbs the solid impurities containing magnetic metal particles in the liquid onto the surface of the magnetic rod 201. The filter bag body 2 blocks the remaining non-magnetic non-metallic substances in the liquid inside. When it is necessary to discharge the solid impurities inside the filter bag body 2, the valve on the drain pipe 104 can be opened, so that the solid impurities inside the filter bag body 2 will be discharged directly from the drain pipe 104. At the same time, when disassembling and transferring the end cap 3, the flange seat on the end cap 3 and the cylinder 1 is unscrewed, and the handwheel 401 is controlled to move spirally upward on the rotating arm 4. The handwheel 401 drives the end cap 3 to move up and down, thereby opening the cylinder 1. Then, the rotating arm 4 is controlled to rotate, so that the rotating arm 4 will drive the end cap 3 to be misaligned with the cylinder 1. At this time, the magnetic rod 201 inside the filter bag body 2 can be cleaned. Example 2

[0022] Please see Figure 1 and Figure 3 Based on Example 1, the gap between the end cap 3 and the cylinder 1 is sealed by the gasket 101 to prevent liquid leakage.

[0023] Specifically, the flange seat at the lower end of the end cap 3 is connected to the flange seat at the upper end of the cylinder 1 by bolts. The outer wall of the end cap 3 is fixed with a vent pipe 301 and a pressure gauge 302 that are connected to the inside of the end cap 3. A gasket 101 is provided between the end cap 3 and the cylinder 1, and the end cap 3 and the cylinder 1 press the gasket 101 together.

[0024] The operation process of this embodiment is as follows: the gasket 101 is placed between the end cap 3 and the cylinder 1. After the end cap 3 and the cylinder 1 are connected, the end cap 3 and the cylinder 1 press the gasket 101 tightly, thereby improving the sealing between the end cap 3 and the cylinder 1 and preventing liquid leakage. At the same time, the valve on the vent pipe 301 is opened to depressurize the inside of the cylinder 1 and the end cap 3. The pressure gauge 302 can monitor the air pressure inside the end cap 3 at all times. Example 3

[0025] Please see Figure 2 Based on Example 1, the use of leg-type support 5 ensures the stable operation of cylinder 1.

[0026] Specifically, a nameplate 105 is bolted to the outer side of the cylinder 1, a drain pipe 103 connected to the interior is fixed to the lower end face of the cylinder 1, a leg support 5 is fixed to the outer wall of the cylinder 1, and an electrostatic grounding plate 501 is fixed to the side wall of the leg support 5.

[0027] The operation process of this embodiment is as follows: the model information of the device can be marked by the nameplate 105. At the same time, after the liquid inside the cylinder 1 is filtered, the valve on the drain pipe 103 can be opened, and the liquid inside the cylinder 1 will be discharged directly from the inside of the drain pipe 103. The cylinder 1 is supported by the leg support 5 to ensure the stability of the cylinder 1. The electrostatic grounding plate 501 on the side wall of the leg support 5 is connected to the ground to reduce the influence of static electricity on the device.
