Description

Technical Field

[0001] This utility model relates to the field of disc filter technology, specifically a disc iron filings filter. Background Technology

[0002] Disc filters are highly efficient filtration devices. They work by removing suspended solids, such as silt, bacteria, and other impurities, from liquids through a series of stacked discs. These discs are composed of fine sand and grit of varying particle sizes; the smaller the particle size of each layer of discs, the better the filtration effect. Disc filters are widely used in industry.

[0003] In the existing production process of polyethylene glycol, it often contains some iron filings. These iron filings are too fine to be cleaned, and the cleaned iron filings are also difficult to remove, which brings great inconvenience to the industrial production of polyethylene glycol. Utility Model Content

[0004] The purpose of this invention is to provide a disc-type iron filings filter. Utilizing a filter disc formed by multiple outer, middle, and inner rings, it can filter passing polyethylene glycol (PEG). An electromagnet is used to adsorb iron filings from the PEG, greatly improving the filtration effect and removal efficiency. After adsorption, the upper electric rod is activated, tilting the filter disc downwards. Simultaneously, the first and second electric rods are activated to open the closed side pipe. Then, the electromagnet power is disconnected, and the adsorbed iron filings are discharged from the drain pipe with the cleaning water flow, improving iron filings cleaning efficiency.

[0005] To achieve the above objectives, a disc-type iron filings filter is provided, comprising: a filter body, an upper electric rod fixedly connected to the inner top surface of the filter body, a fixed disc fixedly connected to the bottom of the upper electric rod, a sliding groove provided at the bottom of the fixed disc, a drainage assembly provided below the fixed disc, a filter assembly provided outside the drainage assembly, an inlet pipe fixedly connected to the top of the filter body, a drain pipe fixedly connected to the circumferential surface of the filter body, a bottom limiting ring fixedly connected to the bottom of the filter body, and a sewage pipe fixedly connected to the bottom of the filter body.

[0006] According to the disc-type iron filings filter, the drainage assembly includes a side pipe, a slider, an upper limit ring, a lower limit ring, a first electric rod, a second electric rod, and an electromagnet. The side pipe is arc-shaped, and a slider is fixedly connected to the top of the side pipe. The slider is located inside the groove. An upper limit ring and a lower limit ring are fixedly connected to the outer arc surface of the side pipe. There are four side pipes and four sliders, forming a complete ring. There are multiple upper limit rings and multiple lower limit rings, which are evenly distributed vertically on the side pipe. Upper limit rings and lower limit rings of the same height form a complete ring. A first electric rod and a second electric rod are fixedly connected to the inner arc surface of the side pipe. There are multiple first electric rods and multiple second electric rods, which are arranged vertically. There are four electromagnets fixedly connected to the inner arc surface of the side pipe, which are symmetrically distributed on the side pipe.

[0007] According to the disc-type iron filings filter, the filter assembly includes ring assemblies and side connecting blocks. Multiple filter assemblies are evenly distributed inside the filter body. Each ring assembly includes an outer ring, an outer connecting ring, a middle ring, an inner connecting ring, and an inner ring. All rings are arc-shaped and fixedly connected. The outer arc surface of the outer ring is fixedly connected to the inner circumferential surface of the filter body. Four ring assemblies are symmetrically arranged. A side connecting block is fixedly arranged between two adjacent ring assemblies. Four side connecting blocks are also provided.

[0008] According to the disc-type iron filings filter, the side pipe is located inside the inner ring and the bottom limiting ring, and the drain pipe is located below the bottom limiting ring. It is used to discharge iron filings during cleaning.

[0009] According to the disc-type iron filings filter, the side tube is made of the same material as the core of the electromagnet, and the electromagnet, the upper electric rod, the first electric rod, and the second electric rod are all electrically connected to an external controller. When the electromagnet is energized, the side tube generates magnetic force, attracting passing iron filings.

[0010] According to the disc-type iron filings filter, the outer connecting ring, inner connecting ring, side connecting block, and bottom limiting ring are all made of elastic rubber, and the outer ring, middle ring, and inner ring are all annular filter discs. This facilitates filtration.

[0011] According to the disc-type iron filings filter, the upper limit ring is located above the filter assembly, and the lower limit ring is located below the filter assembly. When the upper limit ring presses down on the inner ring, the ring assembly can tilt downwards, thereby facilitating the discharge of iron filings. When the lower limit ring moves upwards, the ring assembly can be kept horizontal, facilitating filtration.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a filter body, side pipe, electromagnet, outer ring, outer connecting ring, middle ring, inner connecting ring, inner ring and side connecting block, the filter disc formed by multiple outer rings, middle ring and inner ring can filter the passing polyethylene glycol, and the electromagnet can adsorb the iron filings in the passing polyethylene glycol, which greatly improves the filtration effect and removal efficiency of iron filings.

[0014] 2. By setting up an upper electric rod, a fixed plate, a side tube, a slider, an upper limit ring, a lower limit ring, a first electric rod, a second electric rod, a bottom limit ring, and a drain pipe, after the iron filings are adsorbed, the upper electric rod is activated to tilt the filter plate downwards. At the same time, the first and second electric rods are activated to open the closed side tube. Then, the electromagnet power supply is disconnected, and the adsorbed iron filings can be discharged from the drain pipe with the cleaning water flow, improving the iron filings cleaning efficiency.

The upper limit ring 403 and the lower limit ring 404 are fixedly connected to the outer arc surface of the side pipe 401. There are four side pipes 401 and four sliders 402, forming a complete ring. When closed, the rings block polyethylene glycol, and when open, they discharge iron filings. There are multiple upper limit rings 403 and multiple lower limit rings 404, which are evenly distributed on the side pipe 401. The upper limit rings 403 and the lower limit rings 404 at the same height form a complete ring. The first electric rod 405 is fixedly connected to the inner arc surface of the side pipe 401. 5. Multiple electric rods 405 and 406 are provided, arranged vertically. Opposite side tubes 401 are connected by electric rods 405 or 406. When the electric rods 405 and 406 are activated, the four side tubes 401 are opened to form a channel for discharging iron filings. Electromagnets 407 are fixedly connected to the inner arc surface of the side tubes 401. There are four electromagnets 407, which are symmetrically distributed on the side tubes 401. The iron cores of the side tubes 401 and the electromagnets 407 are made of the same material. When the electromagnets 407 are energized, magnetic force is generated on the side tubes 401, thereby adsorbing the iron filings in the passing polyethylene glycol liquid onto the surface. After filtration is completed, the four side tubes 401 are opened, the power supply to the electromagnets 407 is disconnected, and the iron filings are discharged from the inside of the side tubes 401 under the action of injected clean water.

[0026] The filter assembly 5 includes ring components and side connecting blocks 506. Multiple filter assemblies 5 are evenly distributed inside the filter body 1. Each ring assembly includes an outer ring 501, an outer connecting ring 502, a middle ring 503, an inner connecting ring 504, and an inner ring 505. The outer ring 501, outer connecting ring 502, middle ring 503, inner connecting ring 504, and inner ring 505 are all arc-shaped and fixedly connected. The outer arc surface of the outer ring 501 is fixedly connected to the inner circumferential surface of the filter body 1. Four ring assemblies are provided, symmetrically arranged. A side connecting block 506 is fixedly provided between adjacent ring assemblies. Four side connecting blocks 506 are provided. An upper limit ring 403 is located above the filter assembly 5, and a lower limit ring 404 is located below the filter assembly 5. When the upper limit ring 403 presses down on the inner ring 505, the ring assembly tilts downwards, facilitating the discharge of iron filings. When the lower limit ring 404 moves upwards, the ring assembly remains horizontal, facilitating filtration.

[0027] The outer connecting ring 502, inner connecting ring 504, side connecting block 506 and bottom limiting ring 8 are all made of elastic rubber. The outer ring 501, middle ring 503 and inner ring 505 are all annular filter discs used to filter polyethylene glycol liquid. The side pipe 401 is located inside the inner ring 505 and bottom limiting ring 8. The drain pipe 9 is located below the bottom limiting ring 8.

[0028] Electromagnet 407, upper electric rod 2, first electric rod 405 and second electric rod 406 are all electrically connected to an external controller.

[0029] Working principle: Polyethylene glycol is injected into the filter body 1 through the inlet pipe 6. When the electromagnet 407 is activated, the side pipe 401 generates a magnetic force to attract iron filings in the passing polyethylene glycol liquid. After being filtered by multiple filter components 5, the polyethylene glycol is discharged from the drain pipe 7, and the iron filings are left on the side pipe 401. Then, the upper electric rod 2 is activated, causing the fixed plate 3 and the drainage component 4 to move down. The upper limit ring 403 presses down on the inner ring 505, causing the ring assembly to tilt downward. At the same time, the first electric rod 405 and the second electric rod 406 are activated to open the opposite side pipes 401. Then, the power supply to the electromagnet 407 is disconnected, and clean water is injected from the inlet pipe 6. After being rinsed by clean water, the iron filings flow inward and downward between the adjacent side pipes 401, carrying away the iron filings, and finally discharged from the drain pipe 9.
