Description

Technical Field

[0001] This utility model relates to the field of crude silicone rubber production, and more specifically, it relates to a multi-stage sedimentation device for crude silicone rubber. Background Technology

[0002] Silicone rubber is very common in industrial production. As a type of synthetic rubber, it is widely used in various products. In the production of crude silicone rubber, a large amount of silica is often required. Crude silicone rubber is formed by mixing silica with rubber. In the silica production process, a precipitation device is generally required to collect the precipitate produced by the reaction of raw materials. Existing precipitation devices generally separate the precipitate from the reactants by allowing it to settle, which facilitates the collection of the precipitate. However, since the settling time is long, the efficiency of precipitate collection is low. In addition, after the precipitation is completed, the precipitate remains at the bottom of the device and needs to be removed from the device using other collection tools or equipment. Therefore, the process of collecting the precipitate is relatively complicated and time-consuming. Utility Model Content

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a multi-stage sedimentation device for crude silicone rubber, which has the following beneficial effects: 1. This utility model, by setting up a first sedimentation tank and a second sedimentation tank, allows raw materials to be added and mixed in the first sedimentation tank or other external mixing device during the production of precipitates, thereby reacting and producing precipitates. The precipitates settle in the first sedimentation tank. The first and second sedimentation tanks are connected by a gap, and the raw materials enter the second sedimentation tank through the filter holes opened in the baffle plate. The precipitates produced by the reaction cannot pass through the baffle plate. After the raw materials enter the second sedimentation tank, the liquid level gradually rises in the second sedimentation tank and passes through the filter screen. The precipitates produced in the second sedimentation tank cannot pass through the filter screen and pass through the drain outlet opened on the second sedimentation tank, thus discharging the entire device. In this way, the precipitates can be collected during the liquid flow process, thereby increasing the production efficiency of silicon.

[0013] 2. By setting a first lifting structure, when the precipitate in the first sedimentation tank is removed, the electric push rod set on the support frame drives the lifting frame to rise, thereby lifting the precipitate out of the first sedimentation tank through the cooperation of the fixed frame and the first collecting plate. The first collecting plate is removed from the mounting frame through the cooperation of the matching groove and the matching block, which facilitates the extraction of the precipitate and makes it easier to extract the precipitate after the reaction is completed.

[0014] 3. By setting a second lifting structure, when the precipitate in the second sedimentation tank is removed, the electric push rod retracts to drive the lifting frame to rise and the connecting frame to move. This drives the first lifting structure to rise and the second lifting structure to rise, thereby driving the second collecting plate on the connecting frame to rise and extract the precipitate in the second sedimentation tank. This facilitates the extraction of precipitate by the entire sedimentation device and facilitates the production of silica. Attached Figure Description

Block 18, scraper 18 is provided in multiple ways, scraper 18 cooperates with fixed frame 5, second collection plate 8 cooperates with second sedimentation tank 2, mounting column 19 is fixedly provided on lifting frame 3, mounting column 19 is provided in multiple ways, mounting hole 20 is provided on connecting frame 7, mounting column 19 cooperates with mounting hole 20, the top of mounting column 19 is provided with thread, limit piece 21 is detachably provided on mounting column 19, limit piece 21 is provided in multiple ways, limit piece 21 is provided with thread, limit piece 21 is threadedly connected to mounting column 19, support block 22 is fixedly provided on lifting frame 3, filter screen 23 is provided on support block 22, both ends of filter screen 23 are fixedly provided with protruding block 24, notch 25 is provided on support block 22, protruding block 24 and notch 25 cooperate with each other, locking block 26 is rotatably provided on support block 22, and damping is provided between locking block 26 and support block 22; Specifically, during the production of precipitates, raw materials are added and mixed in the first sedimentation tank 1 or other external mixing device, resulting in a reaction that produces precipitate. The precipitate settles in the first sedimentation tank and is connected to the second sedimentation tank 2 through a gap 9. The raw materials enter the second sedimentation tank 2 through the filter holes 13 on the baffle plate 12. The precipitate produced by the reaction cannot pass through the baffle plate 12. After the raw materials enter the second sedimentation tank 2, the liquid level gradually rises in the second sedimentation tank 2 and passes through the filter screen 23. The precipitate produced in the second sedimentation tank 2 cannot pass through the filter screen 23 and passes through the drain outlet 15 on the second sedimentation tank 2, thus discharging the entire device. This allows for the collection of precipitates even during the liquid flow process. This increases the production efficiency of silicon. When removing the precipitate from the first precipitation tank 1, the electric push rod 14 on the support frame 4 drives the lifting frame 3 to rise, thereby lifting the precipitate out of the first precipitation tank 1 through the cooperation of the fixed frame 5 and the first collecting plate 6. The first collecting plate 6 is removed from the mounting frame through the cooperation of the mating groove 16 and the mating block, thus facilitating the extraction of the precipitate. When removing the precipitate from the second precipitation tank 2, the retraction of the electric push rod 14 drives the lifting frame 3 to rise and simultaneously drives the connecting frame 7 to move, thereby driving the first lifting structure to rise and simultaneously driving the second lifting structure, thereby driving the second collecting plate 8 on the connecting frame 7 to rise, thus extracting the precipitate in the second precipitation tank 2.

[0024] In summary, when using it as a whole: When producing precipitates, raw materials are added and mixed in the first sedimentation tank 1 or other external mixing device, thereby reacting to produce precipitates. The precipitates settle in the first sedimentation tank and are connected to the second sedimentation tank 2 through the gap 9. The raw materials enter the second sedimentation tank 2 through the filter holes 13 on the baffle plate 12. The precipitates produced by the reaction cannot pass through the baffle plate 12. After the raw materials enter the second sedimentation tank 2, the liquid level gradually rises in the second sedimentation tank 2 and passes through the filter screen 23. The precipitates produced in the second sedimentation tank 2 cannot pass through the filter screen 23 and pass through the drain outlet 15 on the second sedimentation tank 2 and are discharged from the entire device. Thus, the precipitates can be collected during the liquid flow, thereby increasing the production efficiency of silicon.

[0025] When the sediment in the first sedimentation tank 1 is removed, the electric push rod 14 on the support frame 4 drives the lifting frame 3 to rise, thereby removing the sediment from the first sedimentation tank 1 through the cooperation of the fixed frame 5 and the first collection plate 6. The first collection plate 6 is removed from the mounting frame through the cooperation of the mating groove 16 and the mating block, thus facilitating the extraction of the sediment.

[0026] When the sediment in the second sedimentation tank 2 is removed, the retraction of the electric push rod 14 drives the lifting frame 3 to rise and the connecting frame 7 to move. This drives the first lifting structure to rise and the second lifting structure to rise, thereby driving the second collecting plate 8 set on the connecting frame 7 to rise and extract the sediment in the second sedimentation tank 2.
