Description

Technical Field

[0001] The utility model relates to the technical field of slurry valves, in particular to a slurry valve protection device. Background Art

[0002] In the aluminum production process, many materials need to be decomposed. A decomposition tank is used in this process. The decomposition tank is often set at a higher position. A slurry valve is set at the bottom of the decomposition tank to control the inflow and outflow of slurry. A handle is set on the side of the slurry valve to drive the threaded rod to move, thereby controlling the opening and closing of the slurry valve.

[0003] In the existing production process, extra slurry will leak out of the decomposition tank, and the leaked slurry falls from a high altitude and lands on the slurry valve. After a period of time, the slurry adheres to the handle and the threaded rod. When the slurry valve needs to be adjusted, the handle is not easy to turn due to the attached slurry, which increases the difficulty of the adjustment process. When the slurry adheres to the slurry valve for a long time, the wear of the slurry valve will be accelerated. When the threaded rod is extended, the slurry adheres to the threaded section, affecting the reciprocating motion of the threaded rod. After long-term use, the sealing quality of the sealing plate is reduced, and some slurry will be sprayed out from the sealing plate position. The high-speed sprayed slurry will cause harm to the workers. Utility Model Content

[0029] like Figure 1 , 2As shown in , 3, and 6, the cleaning assembly includes a limit block 22 and a cleaning rod 23 that can slide inside the limit block 22. The limit block 22 is arranged around the through hole 21, and a slide groove is arranged through the limit block 22. The cleaning rod 23 is arranged in the slide groove. The cleaning rod 23 slides in the slide groove. One end of the cleaning rod 23 is closely set to the partition. When the cleaning rod 23 slides, the surface of the partition is cleaned to scrape away the slurry. The scraping and brushing cleaning is performed regularly to ensure that the internal situation of the slurry valve 1 can be understood in time. A baffle is arranged on one side of the upper cover plate 2. 24 and a support groove 25, the baffle 24 is arranged near the through hole 21, the support groove 25 is arranged below the baffle 24, the support groove 25 extends into the upper cover 2, one end of the cleaning rod 23 is in close contact with the baffle 24 and extends into the support groove 25, and is slidably arranged in the support groove 25, the baffle 24 is arranged above the support groove 25, the falling slurry is blocked by the baffle 24, so that the slurry does not fall into the support groove 25, and the cleaning rod 23 extends to the side of the upper cover 2, and the falling slurry will not affect the sliding of the cleaning rod.

[0030] like Figure 1 , 2 As shown in Figures 4 and 6, a block I26 is provided in the upper cover plate 2, and a block II31 is provided in the lower cover plate 3. Block I26 and block II31 are provided at the position of the sealing plate 102. Block I26 and block II31 are hollow inside. When block I26 and block II31 are connected, the sealing plate 102 is received therein. When there is a problem with the sealing of the slurry valve 1 and the slurry sprays out, block I26 and block II31 can block the slurry to prevent it from affecting the slurry valve 1 and also avoiding harm to the workers. An opening 32 is also provided at the bottom of the lower cover plate 3. The opening 32 is provided at the position of block II31. The slurry blocked inside flows out from the opening 32, which avoids the accumulation of slurry inside and causing a greater impact. At the same time, the sealing condition can be understood by observing the slurry falling in the opening 32.

[0031] like Figure 1 , 2 As shown in Figures 3, 5 and 6, a side cover 4 is provided at one end of the upper cover plate 2, and a connecting groove Ⅰ41 and a connecting groove Ⅱ42 are provided on the side cover 4.

Insert the bolts into the connecting buckles 27 to fix the upper cover plate 2 and the lower cover plate 3. At this time, the upper cover plate 2 is facing the decomposition tank. When the decomposition tank is working, part of the slurry falls onto the protective device. When the slurry accumulates on the surface of the partition and affects the observation, the cleaning rod 23 is pushed back and forth to brush the surface of the partition clean, so as to facilitate the observation of the movement of the threaded rod 101. When the threaded rod 101 moves into the slurry valve 1, the scraper 43 scrapes the slurry in the thread gap. When the internal sealing plate 102 sprays out the slurry, it is blocked by the block I 26 and the block II 31 and flows out from the opening 32, thereby protecting the slurry valve 1 to the maximum extent and preventing the slurry from adhering to the surface of the slurry valve 1 and reducing its working efficiency.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
