[0030] Example 1

[0031] like Figure 1-4 As shown, the present invention proposes a vertical single-cylinder filter, which includes a cylinder, an outlet 2, an inlet 3, a filter basket 7, and a filter assembly.

[0032] The liquid outlet 2 and the liquid inlet 3 are symmetrically installed on both sides of the cylinder, and both the liquid outlet 2 and the liquid inlet 3 are connected to the cylinder. When in use, the liquid delivered by the liquid inlet 3 flows through the cylinder to the liquid outlet 2, so that the liquid is filtered in the cylinder.

[0033] The filter basket 7 is installed inside the cylinder and its opening is tilted towards the liquid inlet 3. The top edge of the filter basket 7 is provided with a pressing component that connects to the top of the cylinder and limits the position of the filter basket 7 in use.

[0034] The filter assembly is installed in the middle of the filter basket 7 and is arranged at an angle toward the liquid inlet 3. It is used to pre-filter the liquid inlet 3 during use to prevent the liquid delivered by the liquid inlet 3 from directly rushing toward the liquid outlet 2, causing impurities to accumulate on the filter basket 7 at the liquid outlet 2 and affecting the subsequent filtration effect.

[0035] In this embodiment, liquid is supplied to the cylinder through the inlet 3 and flows through the cylinder to the outlet 2. During the flow, impurities are effectively separated by the interception effect of the filter assembly, preventing them from accumulating at the outlet 2. At the same time, the inclined setting of the filter assembly allows the subsequently supplied liquid to push the impurities on the filter assembly towards the inside of the filter basket 7. Meanwhile, the filter basket 7 filters both the liquid filtered by the filter assembly and the liquid inside the filter basket 7, ensuring that impurities are effectively intercepted and preventing the liquid from directly flushing impurities to the outlet 2, thus significantly improving the filtration effect.

[0036] Example 2

[0037] like Figure 1-2 As shown, the present invention proposes a vertical single-cylinder filter. Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that the cylinder body includes a cylinder body 1, a cover plate 4, and a support ring 10.

[0038] The cover plate 4 is bolted to the top of the cylinder body 1 and connected to the pressing assembly. It is used to open the top of the cylinder body 1 during use, making it easy to disassemble and assemble the internal structure of the cylinder body 1 and making it easier to clean the filter basket 7.

[0039] The support ring 10 is installed obliquely on the inner side of the cylinder body 1 to support the filter basket 7 during use, so that the oblique opening of the filter basket 7 faces the cover plate 4 and the liquid inlet 3, so that the filter basket 7 filters the liquid delivered by the liquid inlet 3.

[0040] Example 3

[0041] like Figure 3 As shown, the vertical single-cylinder filter proposed in this utility model differs from Embodiment 1 in that the pressing assembly includes a pressing rod 5 and a connecting ring 14.

[0042] There are multiple pressure rods 5, and the multiple pressure rods 5 are arranged at the top edge of the filter basket 7 at equal angles according to the center of the cylinder body 1.

[0043] The connecting ring 14 is located at the top of the pressure rod 5 and is connected to the cover plate 4.

[0044] In an optional embodiment, the top edge of the filter basket 7 is provided with a connecting groove 16. When the pressure rod 5 and the filter basket 7 are installed together, the bottom end of the pressure rod 5 is accommodated in the connecting groove 16. This is used to limit the position of the pressure rod 5 during use and prevent the bottom end of the pressure rod 5 from moving.

[0045] In an optional embodiment, a gasket 8 is provided above the support ring 10 and connected to the filter basket 7, which is used to seal between the filter basket 7 and the support ring 10 during use, to ensure that the liquid does not leak during the filtration process and improve the overall sealing performance.

[0046] In an optional embodiment, the bottom edge of the filter basket 7 is provided with a rod 9, and the top end of the support ring 10 is provided with a slot 12. The bottom end of the rod 9 passes through the gasket 8 and is inserted into the slot 12 to limit the position of the filter basket 7 during use and prevent the filter basket 7 from shifting during use.

[0047] In this embodiment, multiple pressure rods 5 are connected as one unit by a connecting ring 14, and the bottom end of the pressure rod 5 is inserted into the connecting groove 16. At the same time, when the cover plate 4 is bolted to the cylinder body 1, the cover plate 4 exerts pressure on the connecting ring 14, causing the connecting ring 14 to exert pressure on the filter basket 7 through the pressure rod 5, thereby causing the filter basket 7 to drive the gasket 8 to compress, fixing the filter basket 7 to the inside of the cylinder body 1, and improving the sealing performance of the connection between the filter basket 7 and the gasket 8.

[0048] Example 4

[0049] like Figure 4 As shown, the present invention proposes a vertical single-cylinder filter. Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that the filter assembly includes a filter plate 6 and a connecting shell 11.

[0050] There are two connecting shells 11, which are symmetrically installed at the middle edge of the filter basket 7 and extend to the inside of the filter basket 7.

[0051] The filter plate 6 is fitted and installed inside the connecting shell 11.

[0052] In an optional embodiment, a pin 13 is provided on the side of the connecting shell 11. The end of the pin 13 extends through the connecting shell 11 and the filter plate 6 to the other side of the connecting shell 11. A retaining spring 15 is provided at the end of the pin 13. The retaining spring 15 is connected to the other side of the connecting shell 11 for detachable connection between the connecting shell 11 and the filter plate 6 during use, making it easier to clean the filter plate 6 and the filter basket 7.

[0053] In this embodiment, by symmetrically and obliquely installing two connecting shells 11 in the middle of the filter basket 7, and fitting the filter plate 6 into the inner side of the two connecting shells 11, and connecting the pin 13 through the connecting shell 11 and the filter plate 6 to the snap ring 15, the filter plate 6 is ensured to be stable and easy to disassemble. When the filter plate 6 filters the liquid delivered by the inlet 3, the liquid delivered by the inlet 3 moves the impurities on the surface of the filter plate 6 along the oblique surface of the filter plate 6 to the inner side of the filter basket 7, so that the filter plate 6 performs cleaning work while filtering.

[0054] In this invention, when the cover plate 4 is bolted to the cylinder body 1, the cover plate 4 exerts pressure on the connecting ring 14, causing the connecting ring 14 to exert pressure on the filter basket 7 through the pressure rod 5. This causes the filter basket 7 to compress the gasket 8, sealing and fixing the filter basket 7 to the inside of the cylinder body 1. Simultaneously, liquid is supplied to the outlet 2 through the inlet 3. As the liquid passes through the cylinder body 1, impurities are effectively separated by the interception effect of the filter plate 6, preventing impurities from accumulating on the filter basket 7 at the outlet 2. Furthermore, the inclined setting of the filter plate 6 causes the impurities on the surface of the filter plate 6 to move along the inclined surface of the filter plate 6 to the inside of the filter basket 7. This allows the filter plate 6 to perform cleaning while filtering, and the filter basket 7 filters both the liquid filtered by the filter plate 6 and the liquid inside the filter basket 7, ensuring that impurities are effectively intercepted and preventing the liquid from directly flushing impurities to the outlet 2, thus significantly improving the filtration effect.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
