Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a liquid filtration device and a feeder. Background Technology

[0002] In the tobacco processing industry, to improve the quality of tobacco shreds, it is usually necessary to use feeding equipment to process the tobacco leaves. By spraying carefully formulated liquids (including sugars, flavorings, humectants, etc.) onto the surface of the tobacco shreds, the inherent deficiencies of the tobacco raw materials are compensated for, product quality is stabilized, and the product's unique style is highlighted.

[0003] However, during the preparation, storage, and transportation of the spray solution, tiny crystals, precipitates, or flocculent matter may form due to microbial activity. Furthermore, trace amounts of impurities or scale may detach from pipes and equipment. Once these tiny particles enter the spraying system, they can easily clog the nozzles with their extremely small openings. Therefore, a spray solution filtration device is necessary to intercept these impurities.

[0004] However, the screens in the currently used liquid filtration devices are usually fixed on both sides of the filter body with two layers of screens, which makes it easy for impurities to get stuck in the gap between the two layers of screens, causing screen blockage, which in turn increases the feeding resistance, affects the smooth passage of liquid, and consequently affects the feeding accuracy of the feeding equipment.

[0005] Therefore, there is an urgent need for a liquid filtration device and a feeder to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a liquid filtration device and a feeder to solve the problems of inconvenient cleaning, easy clogging of impurities, easy blockage of filter screens, and inconvenient maintenance that easily occur when the liquid filtration device is used for a long time in the prior art.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] One aspect provides a liquid filtration device, installed at the liquid outlet of a feeder, comprising:

[0009] The screen body is hollow and includes a filtering part and a connecting part. The filtering part is provided with a first filter screen, and the connecting part is provided with an outwardly protruding limiting member.

[0010] The second filter screen is arranged inside the first filter screen;

[0011] A filter cover is detachably connected to the limiting member; the filter cover can fix the second filter screen inside the filter cover and the screen body;

[0012] The mesh size of the first filter screen is smaller than that of the second filter screen. The liquid is discharged after passing through the first filter screen and the second filter screen in sequence.

[0013] Optionally, the second filter screen is tightly fitted to the first filter screen.

[0014] Optionally, one of the limiting member and the filter cover is provided with an external thread, and the other is provided with an internal thread, and the limiting member is threadedly connected to the filter cover.

[0015] Optionally, an anti-loosening structure is provided between the limiting member and the filter cover.

[0016] Optionally, the filter cover has a positioning hole, and a positioning bolt is provided in the positioning hole, which can abut against the limiting member.

[0017] Optionally, a handle is provided on the side of the filter cover away from the screen body.

[0018] Optionally, the handle includes a first connecting rod, a gripping rod, and a second connecting rod connected in sequence, with the ends of the first connecting rod and the second connecting rod away from the gripping rod both fixedly connected to the filter cover.

[0019] Optionally, the second filter screen has a mesh size of 70.

[0020] Optionally, the first filter screen, the second filter screen, and the filter cover are all made of stainless steel.

[0038] like Figures 1 to 4 As shown, this embodiment provides a liquid filtration device, installed at the outlet of a feeder. The liquid filtration device includes a screen body 1, a second filter screen 2, and a filter cover 3. The screen body 1 is hollow and includes a filtering section and a connecting section. The filtering section has a first filter screen 11, and the connecting section has an outwardly protruding limiting member 12. The second filter screen 2 is disposed within the first filter screen 11. The filter cover 3 is detachably connected to the limiting member 12. The filter cover 3 can fix the second filter screen 2 within the filter cover 3 and the screen body 1. The mesh size of the first filter screen 11 is smaller than that of the second filter screen 2, and the liquid is discharged after passing through the first filter screen 11 and the second filter screen 2 sequentially.

[0039] It is understood that the liquid filtration device provided in this embodiment, by enclosing a second filter screen 2 within the first filter screen 11 of the screen body 1, can perform two-stage filtration of the liquid, effectively intercepting impurities and debris in the liquid, preventing filter screen blockage or affecting subsequent processes. Simultaneously, the filter cover 3 is detachably connected to the filter cover 3 on the screen body 1, allowing the second filter screen 2, located inside the first filter screen 11, to be detachable. When the liquid filtration device needs cleaning or maintenance, simply remove the filter cover 3 to remove the second filter screen 2, facilitating thorough cleaning of the liquid filtration device. This effectively solves the problem of impurities easily accumulating between the first filter screen 11 and the second filter screen 2 in existing liquid filtration devices, causing inconvenience in cleaning and affecting the filtration effect, effectively ensuring the cleanliness and filtration effect of the liquid filtration device. The opening size on the first filter screen 11 is larger than the opening size on the second filter screen 2. This arrangement creates a finer filtration structure, improving the liquid filtration device's ability to intercept small impurities in the liquid, further preventing impurities from entering subsequent processes and affecting the quality of the tobacco or causing nozzle blockage.

[0040] For example, the first filter screen 11, the second filter screen 2, and the filter cover 3 are all made of stainless steel. It is understood that the use of stainless steel provides excellent corrosion resistance, preventing the leaching of metal ions from the feed liquid and thus contaminating it, effectively ensuring the quality of subsequent tobacco production. Furthermore, the smooth surface of stainless steel makes it less prone to material adhesion, facilitating efficient cleaning of the feed liquid filtration device. It also allows for good performance recovery after cleaning, enabling multiple reuses and reducing consumable costs.

[0041] Specifically, in this embodiment, the second filter screen 2 has a mesh size of 70, which can block and filter impurities in the liquid while having low flow resistance, thus enabling the liquid to have a large flow rate.

[0042] More specifically, in this embodiment, both the filter cover 3 and the first filter screen 11 are made of food-grade stainless steel, further ensuring the filtration quality of the liquid.

[0043] Furthermore, in some embodiments, the second filter screen 2 is tightly fitted to the first filter screen 11. It is understood that by tightly fitting the second filter screen 2 and the first filter screen 11 together, the space between the second filter screen 2 and the first filter screen 11 can be reduced, reducing the possibility of impurities accumulating between the second filter screen 2 and the first filter screen 11, thereby ensuring the cleanliness and filtration efficiency of the liquid filtration device.

[0044] Specifically, in this embodiment, the second filter screen 2 is interference-fitted with the first filter screen 11.

[0045] The opening size on the first filter screen 11 is larger than the opening size on the second filter screen 2. This configuration creates a finer filtration structure, improving the ability of the liquid filtration device to intercept small impurities in the liquid, and further preventing impurities from entering subsequent processes and affecting the quality of the tobacco or causing nozzle blockage.

[0046] Furthermore, in some embodiments, one of the limiting member 12 and the filter cover 3 is provided with an external thread, and the other is provided with an internal thread, and the limiting member 12 and the filter cover 3 are threadedly connected. It is understood that the limiting member 12 and the filter cover 3 can be locked together by rotation to fix the second filter screen 2 in the screen body 1, or can be rotated apart to facilitate the removal of the second filter screen 2.

[0047] Specifically, in this embodiment, such as Figure 2 and Figure 4 As shown, the filter cover 3 is annular. A limiting member 12 is positioned above the first filter screen 11, and external threads are provided on the outer periphery of the limiting member 12. A connecting groove is provided on the filter cover 3; the inner wall of the connecting groove on the outer side in the radial direction has internal threads, and the inner wall of the connecting groove on the inner side in the radial direction is in close contact with the second filter screen 2. After the filter cover 3 is threadedly connected to the first filter screen 11, the second filter screen 2 can be fixed between the filter cover 3 and the first filter screen 11. It can be understood that in some embodiments, the bottom of the first filter screen 11 is bent inwards, and one end of the second filter screen 2 abuts against the first filter screen 11 while the other end abuts against the filter cover 3.

[0048] More specifically, to prevent the second filter screen 2 from being damaged by the filter cover 3, a gasket 21 is provided on the second filter screen 2. The gasket 21 is located on the inner ring of the second filter screen 2.

[0049] Furthermore, in some embodiments, an anti-loosening structure is provided between the limiting member 12 and the filter cover 3. It is understood that by providing an anti-loosening structure, the stability of the liquid filtration device during use can be ensured.

[0050] For example, in this embodiment, the filter cover 3 has a positioning hole, and a positioning bolt is provided in the positioning hole. The positioning bolt can abut against the limiting member 12. It can be understood that by setting the positioning bolt to abut against the limiting member 12 through the positioning hole on the filter cover 3, it is possible to avoid gaps between the filter cover 3 and the limiting member 12, which would cause the threaded connection between the filter cover 3 and the limiting member 12 to loosen. This ensures a stable connection between the filter cover 3 and the screen body 1, thereby ensuring that the first filter screen 11 and the second filter screen 2 can work normally, thus ensuring the filtration effect of the liquid.

[0051] Furthermore, in some embodiments, to facilitate the removal of the filter cover 3 from the screen body 1, a handle 4 is provided on the side of the filter cover 3 away from the screen body 1. It is understood that the handle 4 makes it easier for the operator to grip the filter cover 3 and apply force, and after the filter cover 3 is installed on the screen body 1, the handle 4 can also be used to move the liquid filtration device, making it convenient to move the liquid filtration device to the installation position of the feeder.

[0052] Specifically, such as Figure 4 As shown, in this embodiment, the handle 4 includes a first connecting rod 41, a gripping rod 42, and a second connecting rod 43 connected in sequence. The ends of both the first connecting rod 41 and the second connecting rod 43 away from the gripping rod 42 are fixedly connected to the filter cover 3. More specifically, the gripping rod 42 is arranged parallel to the surface of the filter cover 3. It is understood that this arrangement allows the gripping rod 42 to be perpendicular to the axis of the filter cover 3, making it easier for the operator to rotate the filter cover 3 to connect or separate it from the screen body 1. Simultaneously, it facilitates the operator in lifting the liquid filtration device by gripping the rod 42 to place the liquid filtration device in the working position.

[0053] This embodiment also discloses a feeding machine, including a conveying pipeline, a nozzle, and the aforementioned liquid filtration device. One end of the conveying pipeline has an inlet for adding liquid, and the other end has an outlet connected to the nozzle. The nozzle has a liquid outlet, and the liquid filtration device is located at the liquid outlet. Since the feeding machine disclosed in this utility model has the aforementioned liquid filtration device, it at least possesses the beneficial effects of the aforementioned liquid filtration device, which will not be repeated here.

[0054] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
