[0029] Example

[0030] like Figure 1-4 As shown, the utility model proposes a device for preventing blocking of dilute acid pipelines for acid production from smelting flue gas, comprising an anti-blocking pipe 1 installed at one end of the dilute acid pipeline. A filter assembly 2 for filtering is movably arranged in the anti-blocking pipe 1, and the filter assembly 2 comprises a filter plate 21 arranged in the anti-blocking pipe 1, and a plurality of filter holes 211 are provided on the filter plate 21, which are used to filter tiny particles in the dilute acid to prevent them from entering the pipeline, thereby preventing the pipeline from being blocked. The filter assembly 2 also comprises a mounting plate 22, a handle 23, and a sealing gasket 24. The mounting plate 22 is arranged in a semicircular ring shape, and the cross section of the mounting plate 22 is a T-shaped structure and the filter plate 21 is installed on the side of the mounting plate 22 close to the anti-blocking pipe 1. The handle 23 is fixedly connected to the side of the mounting plate 22 away from the filter plate 21, and the handle 23 drives the mounting plate 22 to move synchronously when moving. The anti-blocking pipe 1 is provided with a mounting groove 11 that matches the mounting plate 22, so as to facilitate the mounting plate 22 to be installed on the outside of the anti-blocking pipe 1. The sealing gasket 24 is installed on the side of the mounting plate 22 close to the mounting groove 11, and is used for the mounting plate 22 to squeeze the sealing gasket 24 after the mounting plate 22 is installed, so as to enhance the sealing and prevent leakage of dilute acid. The filter assembly 2 also includes a limiting ring 25 and a mounting ring 26. Two groups of limiting rings 25 are fixedly connected to one end of the mounting plate 22 close to the filter plate 21, and the limiting rings 25 move synchronously with the mounting plate 22. The two groups of limiting rings 25 are respectively arranged on both sides of the filter plate 21, and the cross-sections of the limiting rings 25 are both L-shaped structures. The two groups of mounting rings 26 are respectively fixedly connected to both sides of the filter plate 21, and the mounting rings 26 move synchronously with the filter plate 21. The mounting ring 26 is slidably connected to the limiting ring 25, and is used for the filter plate 21 to be slidably connected between the two groups of limiting rings 25 through the two groups of mounting rings 26, so that the filter plate 21 can be installed on the side of the mounting plate 22. The limiting ring 25 and the mounting ring 26 are both arranged in a semicircular shape, so that the filter plate 21 can be removed after rotating half a circle, so as to facilitate replacement.

[0031] For details, please refer to Figure 1The anti-blocking device also includes a plurality of fixing mechanisms 3 installed on the top of the anti-blocking pipe 1 for fixing the position of the filter assembly 2. The fixing mechanism 3 includes a fixing column 31 and a rotating plate 32. The two fixing columns 31 are symmetrically arranged on both sides of the mounting plate 22 and fixedly connected to the top of the anti-blocking pipe 1. The position of the fixing column 31 is fixed. The rotating plate 32 is rotatably connected to a group of fixing columns 31. One end of the rotating plate 32 away from a group of fixing columns 31 is clamped on another group of fixing columns 31, so that the rotating plate 32 can be perpendicular to the mounting plate 22 after rotation, which is convenient for fixing the mounting plate 22. At the same time, the rotating plate 32 can also be rotated away from the top of the mounting plate 22, so as to facilitate the replacement of the filter plate 21 by lifting the mounting plate 22 upward. The fixing mechanism 3 also includes a threaded sleeve 33 and a threaded rod 34. The threaded sleeve 33 is arranged in the middle position of the rotating plate 32, and the threaded rod 34 is threadedly connected to the threaded sleeve 33, so that the threaded rod 34 can move along its own length direction when rotating. The fixing mechanism 3 also includes a pressure column 35 and a positioning groove 36. The pressure column 35 is installed on the top of the mounting plate 22 and corresponds to the threaded sleeve 33. The positioning groove 36 is opened at the top of the pressure column 35. One end of the threaded rod 34 slides into the positioning groove 36, so that the threaded rod 34 can enter the positioning groove 36 after moving downward, thereby pressing the pressure column 35 downward, and then pressing the mounting plate 22 on the surface of the anti-blocking pipe 1 to achieve fixation.

[0032] In this embodiment, when the dilute acid passes through the filter plate 21, the tiny particles therein are filtered, thereby preventing blockage in the pipeline and ensuring the safe and stable operation of the production system. When the filter plate 21 needs to be cleaned, the threaded rod 34 is rotated with a wrench. Since the threaded rod 34 is threadedly connected to the threaded sleeve 33, the threaded rod 34 can move upward, so that the threaded rod 34 no longer presses the mounting plate 22 downward. When the bottom end of the threaded rod 34 is completely located above the positioning groove 36, the rotating plate 32 is rotated so that the rotating plate 32 leaves the mounting plate 22. At this time, the mounting plate 22 is held by hand and lifted upward, and the filter plate 21 is driven to leave the anti-blocking pipe 1. At this time, the filter plate 21 can be cleaned. When the filter plate 21 needs to be replaced, the filter plate 21 can be rotated so that the filter plate 21 rotates under the limiting action of the limiting ring 25 and the mounting ring 26, and the mounting ring 26 is driven to rotate. After rotating half a circle, the mounting ring 26 is completely separated from the limiting ring 25. At this time, a new set of filter components 2 can be replaced and installed on one side of the mounting plate 22. At this time, the filter plate 21 is inserted into the anti-blocking pipe 1 through the installation groove 11, and the installation plate 22 enters the installation groove 11. The rotating plate 32 is rotated to be located above the installation plate 22 again, and one end of the rotating plate 32 is clamped in one of the fixed columns 31. Finally, the threaded rod 34 is rotated with a wrench to move the threaded rod 34 downward, and the bottom end of the threaded rod 34 enters the positioning groove 36 and presses down the pressing column 35, so that the installation plate 22 is pressed on the anti-blocking pipe 1, and the sealing gasket 24 is pressed tightly, which has a good sealing effect, completes the cleaning and maintenance of the filter plate 21, and is simple to operate.

[0033] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
