Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically, it relates to a liquid feed filter. Background Technology

[0002] Liquid feed is mainly used in aquaculture, pig farming, and other livestock farming. Compared to traditional dry feed, liquid feed has higher palatability and digestibility, better meeting the nutritional needs of pigs, reducing feed waste, and improving the economic efficiency of farms. On the one hand, liquid feed can bring direct benefits to farms; on the other hand, it can reduce labor costs. Traditional farming involves manually transporting feed to the feeding area, and the larger the farm, the higher the labor costs.

[0003] To address the aforementioned issues, modern aquaculture utilizes facilities such as mixing tanks, pump units, and sterile pipelines. Feed, prepared according to a specific ratio, is mixed in the mixing tank and then pumped by the pump unit to the sterile pipeline leading to the feeding area. This allows for automatic, timed dispensing, significantly reducing labor costs compared to traditional manual feeding methods. However, pipeline delivery of liquid feed also has drawbacks: the pipelines only have simple coarse-mesh filters, which cannot filter out small stones, iron filings, and other impurities in the liquid feed, affecting its quality. Therefore, a dedicated filter for liquid feed is currently lacking. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a liquid feed filter, comprising a housing, an inlet pipe and an outlet pipe on the side wall of the housing, with the inlet pipe located on one side of the lower part of the housing and the outlet pipe located on the other side of the upper part of the housing; an upwardly extending strip-shaped permanent magnet is provided on the bottom wall of the housing, adjacent to the inlet pipe; and a magnetic filter plate is included, with multiple filter holes distributed on the magnetic filter plate, which is detachably connected inside the housing and located between the inlet pipe and the outlet pipe.

[0005] The preferred embodiment of the liquid feed filter in this utility model is as follows: The inner surface of the housing is provided with two longitudinally distributed guide rails, each guide rail having a longitudinal groove adapted to the magnetic filter plate, and the two longitudinal grooves are directly opposite each other. The magnetic filter plate is inserted along the two longitudinal grooves, making it easy to install and remove. Both sides of the magnetic filter plate are in direct contact with both sides of the longitudinal grooves, with minimal gaps, preventing liquid feed from entering the gaps and ensuring a tight seal.

[0006] The preferred embodiment of the liquid feed filter in this utility model is as follows: the upper and lower ends of the housing are respectively provided with an upper port and a lower port, the upper port is provided with a suitable end cap, and the upper port and the end cap are detachably connected by a flange. After aligning the bolt holes of the two flanges, the bolts are tightened to clamp the sealing gasket between the two flanges and seal the upper port. Conversely, the end cap can be separated after the bolts are removed, and the magnetic filter plate can be taken out.

[0007] The preferred embodiment of the liquid feed filter in this utility model is as follows: the lower port is provided with a matching base, the base is fitted onto the lower end of the shell and is detachably connected to the shell by threads. The bottom wall of the base is provided with an upwardly extending inner cylinder, and the side wall of the shell is located between the side wall of the bottom wall and the inner cylinder; the upper edge of the inner cylinder is not higher than the inner cavity of the liquid inlet pipe. The lower port of the base is sealed by threads, and the inner cylinder structure inside the base forms a temporary storage area for impurities. This temporary storage area avoids the flow area of ​​liquid feed and is a stagnant area. Gravel, other debris larger than the filter holes, etc. are intercepted by the magnetic filter plate and fall into the inner cylinder. The flowing liquid feed cannot carry out the debris, which is convenient for cleaning and at the same time prevents the debris from clogging the filter holes.

[0008] The preferred embodiment of the liquid feed filter in this invention is as follows: Multiple strip-shaped permanent magnets are provided, all distributed on the bottom wall of the inner cylinder, and none of the strip-shaped permanent magnets are higher than the top of the inner cylinder. Additionally, semi-circular permanent magnets are provided on the bottom wall of the inner cylinder, with the semi-circular permanent magnets and strip-shaped permanent magnets located on opposite sides of the magnetic filter plate. Ferromagnetic impurities such as iron filings, iron slag, and iron particles are attracted by the strip-shaped permanent magnets when passing above the inner cylinder. The space between the strip-shaped permanent magnets can accommodate non-ferromagnetic impurities, ensuring that the storage of ferromagnetic and non-ferromagnetic impurities does not conflict. The semi-circular permanent magnets have a larger adsorption area and stronger magnetic force, providing secondary filtration of the liquid feed after passing through the magnetic filter plate, thus improving the impurity removal effect.

[0009] The beneficial effects of the liquid feed filter in this utility model are as follows:

[0010] 1. Magnetic filter plates have a dual filtration function. First, they use the physical structure of the magnetic filter plate to intercept non-ferromagnetic impurities larger than the filter holes. Second, they use the magnetism of the magnetic filter plate to filter ferromagnetic impurities. The filtration effect produced by these two filtration methods is significantly better than that of filter screens.

[0011] 2. The inlet pipe is located at the bottom of the shell, and the outlet pipe is located at the top of the shell. The structure is bottom-in and top-out. Heavier non-ferromagnetic impurities enter the shell through the inlet pipe and fall naturally to the bottom wall of the shell under the action of gravity, forming a third filtration method and further improving the filtration effect.

[0012] 3. The magnetic filter plate is detachable, making it easy to clean impurities. Attached Figure Description

[0021] In view of the shortcomings of the prior art, the inventor of this utility model has, through long-term research and extensive practice, proposed the technical solution of this utility model. The following will further explain and illustrate the technical solution, its implementation process, and its principles in conjunction with the accompanying drawings and specific implementation examples.

[0022] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment provides a liquid feed filter, including a housing 1. The side wall of the housing 1 is provided with an inlet pipe 2 and an outlet pipe 3, with the inlet pipe 2 located on one side of the lower part of the housing 1 and the outlet pipe 3 located on the other side of the upper part of the housing 1. It adopts a bottom-inlet, top-outlet structure, utilizing gravity to filter impurities in the liquid feed as a filtration method. In this embodiment, the housing 1 is cylindrical in shape, with an upper port and a lower port at the upper and lower ends, respectively. The upper port is provided with a suitable end cap 4, and the upper surface of the end cap 4 is provided with a handle 5. The upper port and the end cap 4 are detachably connected via flanges 6. After aligning the bolt holes of the two flanges 6, bolts are tightened. The lower port is provided with a suitable base 7, which is fitted onto the lower end of the housing 1 and is detachably connected to the housing 1 via threads. The bottom wall of the base 7 has an upwardly extending inner cylinder 14, and the side wall of the housing 1 is located between the side wall of the bottom wall and the inner cylinder 14. There is a distance between the inlet pipe 2 and the lower port, and the upper part of the inner cylinder 14 is not higher than the inner cavity of the inlet pipe 2, thus forming a stagnant zone 8 inside the inner cylinder 14. Impurities falling into the stagnant zone 8 have little impact on the fluid and are not carried away by the liquid feed, thus avoiding impurities from hindering the flow of liquid feed.

[0023] like Figure 5 and Figure 6 As shown, this embodiment also includes a magnetic filter plate 9, which is uniformly covered with strip-shaped filter holes and is located between the inlet pipe 2 and the outlet pipe 3. The magnetic filter plate 9 utilizes its physical structure to intercept non-ferromagnetic impurities larger than the filter holes. The filtration principle is the same as existing filter screens, but some impurities are intercepted at the filter holes. As the flowing liquid feed continuously impacts the magnetic filter plate 9, the impurities at the filter holes loosen and fall to the inside of the inner cylinder 14, preventing impurities from accumulating at the filter holes of the magnetic filter plate 9 and reducing the filter's resistance. Furthermore, the magnetic properties of the magnetic filter plate 9 are used to filter ferromagnetic impurities, resulting in a triple filtration method and better filtration effect.

[0024] The magnetic filter plate 9 is detachably connected to the inside of the housing 1. The specific connection structure between the magnetic filter plate 9 and the housing 1 is as follows:

[0025] The inner surface of the housing 1 is provided with two longitudinally distributed guide rails 10. Each guide rail 10 has a longitudinal groove 11 that is adapted to the magnetic filter plate 9, and the two longitudinal grooves 11 are directly opposite each other. The magnetic filter plate 9 is inserted along the two longitudinal grooves 11, making it easy to install and remove. Both sides of the magnetic filter plate 9 are in direct contact with both sides of the longitudinal grooves 11, with very small gaps, preventing liquid feed from entering the gaps and ensuring a tight seal.

[0026] like Figure 2 , Figure 3 and Figure 5As shown, to further improve the filtration effect, in this embodiment, the inner cylinder 14 is provided with an upwardly extending strip-shaped permanent magnet 12, which is adjacent to the liquid inlet pipe 2. Specifically, multiple strip-shaped permanent magnets 12 are provided, the number of which is determined by the bottom wall area of ​​the inner cylinder 14. The strip-shaped permanent magnets 12 are evenly distributed on the bottom wall of the inner cylinder 14, and none of them are higher than the top of the inner cylinder 14. In addition, a semi-circular permanent magnet 13 is provided on the bottom wall of the inner cylinder 14. The semi-circular permanent magnet 13 is made of a strong magnetic material with strong magnetic force, while the shell 1, base 7, and end cap 4 are all made of stainless steel. The semi-circular permanent magnet 13 and the strip-shaped permanent magnet 12 are located on both sides of the magnetic filter plate 9. The inner cylinder 14, the strip-shaped permanent magnet 12, and the semi-circular permanent magnet 13 are all no higher than the inner cavity of the liquid inlet pipe 2. This is to ensure that the inner cylinder 14, the strip-shaped permanent magnet 12, and the semi-circular permanent magnet 13 do not obstruct the flow of liquid feed. The inner cylinder 14, the strip-shaped permanent magnet 12, and the semi-circular permanent magnet 13 are all located in the stagnant flow zone 8. Ferromagnetic impurities such as iron filings, iron slag, and iron particles are attracted by the strip-shaped permanent magnet 12 when passing above the inner cylinder 14. The space between the strip-shaped permanent magnets 12 can accommodate non-ferromagnetic impurities, and the storage of ferromagnetic and non-ferromagnetic impurities does not conflict. The semi-circular permanent magnet 13 has a larger adsorption area and stronger magnetic force, performing secondary filtration on the liquid feed after passing through the magnetic filter plate 9, thus improving the impurity removal effect.

[0027] This embodiment rationally connects the magnetic filter plate 9, the inlet pipe 2, and the outlet pipe 3 to obtain two filtration methods. Furthermore, it utilizes the magnetism of the magnetic filter plate 9 and the strip permanent magnet 12 to obtain a third filtration method. The design of the retention area achieves an anti-clogging effect, and the semi-circular permanent magnet 13 provides a secondary filtration effect, making the liquid feed filter of this embodiment a dedicated pipeline liquid feed impurity removal device.
