[0002] White carbon black is a general term for white powdered X-ray amorphous silicic acid and silicate products, mainly precipitated silica, fumed silica and ultrafine silica gel, and also includes powdered synthetic aluminum silicate and calcium silicate. White carbon black has the characteristics of being non-toxic, tasteless and odorless, small particle size, porous, good dispersion performance, large specific surface area, light texture, low density, high temperature resistance, non-flammable, tasteless, odorless, and good electrical insulation. In the production process of white carbon black, the precipitation device is mainly used to mix sodium silicate with reactants such as sulfuric acid, and generate white carbon black through a series of chemical reactions.

[0003] During the precipitation reaction stage, the raw materials and reaction reagents in the precipitation device undergo a chemical reaction inside the device, which will release some waste gas. In order to avoid environmental pollution caused by the waste gas, the waste gas is filtered through a filter element in the exhaust pipe of the precipitation device. However, the filter elements in the exhaust pipe of the current precipitation device are fixedly installed with fasteners, which makes it inconvenient to disassemble and assemble the filter element, making it inconvenient to repair and replace the filter element. Therefore, improvements are now made to the precipitation device used for silica production. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-Figure 3 In the present embodiment, a precipitation device for producing white carbon black is provided, including a precipitation kettle 1, a sealing cover 2 is provided on the top of the precipitation kettle 1, a stirring assembly is provided in the middle of the interior of the precipitation kettle 1, a feed pipe 6 connected to the precipitation kettle 1 is provided on the sealing cover 2, a discharge pipe 7 connected to the precipitation kettle 1 is provided at the bottom of the precipitation kettle 1, an exhaust pipe 8 connected to the precipitation kettle 1 is provided at a position on one side of the feed pipe 6 on the sealing cover 2, and a filter element 9 is detachably installed in the interior of the exhaust pipe 8 through an ejection assembly 10, and a positioning assembly 11 for fixing the filter element 9 in the exhaust pipe 8 is provided on the exhaust pipe 10.

[0023] In the utility model, raw materials and reaction reagents for white carbon black production are fed into the precipitation kettle 1 through the feed pipe 6 on the sealing cover 2, and the raw materials and reaction reagents are fully mixed and reacted after being stirred by the stirring component, and then precipitated in the precipitation kettle 1. During the reaction, the waste gas generated by the reaction is discharged through the exhaust pipe 8, and the waste gas is filtered by the filter element 9 in the exhaust pipe 8. When the filter element 9 needs to be replaced, it is only necessary to open the positioning component 11, and then the filter element 9 is ejected from the exhaust pipe 8 under the ejection action of the ejection component 10, so that the filter element 9 is convenient for maintenance and replacement.

[0024] Specifically, refer to Figure 2 The ejection assembly 10 includes a positioning plate 101 fixed on the inner wall of the exhaust pipe 8, and an ejection spring 103 is arranged on the positioning plate 101 through a connecting terminal 102. The ejection spring 103 is arranged in the exhaust pipe 8 along the axial direction of the exhaust pipe 8 through the positioning plate 101, and the filter element 9 is arranged at the upper end of the ejection spring 103. When the positioning assembly 11 on the exhaust pipe 8 is opened, the ejection spring 103 pushes the filter element 9 upward, so that the filter element 9 pops out of the exhaust pipe 8, which is convenient for the removal of the filter element 9.

[0025] Specifically, refer to Figure 2 and Figure 3 The positioning assembly 11 includes a mounting frame 111 fixed to the outer side of the exhaust pipe 8, a limiting rod 112 is arranged on the mounting frame 111, a baffle 113 is arranged at the middle position of the limiting rod 112, a pull ring 114 is arranged at the end of the limiting rod 112 away from the exhaust pipe 8, and a return spring 115 is sleeved on the limiting rod 112 at a position between the baffle 113 and the mounting frame 111. When the filter element 9 is disassembled, the limiting rod 112 on the mounting frame 111 is pulled outward by the pull ring 114 to shrink the limiting rod 112 to the outside of the exhaust pipe 8. When the limiting rod 112 is no longer pressed on the upper end of the filter element 9, the filter element 9 is ejected by the ejection assembly 10 to achieve disassembly.

[0026] The limiting rod 112 penetrates the mounting frame 111 and is slidably connected to the mounting frame 111. The end of the limiting rod 112 close to the exhaust pipe 8 penetrates the exhaust pipe 8 and abuts against the top of the filter element 9. When the filter element 9 is fixed, the limiting rod 112 penetrates the exhaust pipe 8 under the action of the return spring 115 and presses on the top of the filter element 9, thereby pressing the filter element 9 inside the exhaust pipe 8 to ensure that the filter element will not pop out of the exhaust pipe 8.

[0027] Specifically, refer to Figure 1 The stirring assembly includes a motor 3 fixed on the sealing cover 2, and the output end of the motor 3 is located inside the precipitation tank 1 and is fixedly connected to a connecting shaft 4, and a stirring blade 5 is arranged on the connecting shaft 4. After the raw materials and the reaction reagents are added to the precipitation tank 1, the motor 3 drives the stirring blade 5 on the connecting shaft 4 to rotate, thereby accelerating the reaction speed of the raw materials and the reaction reagents in the precipitation tank 1.

[0028] Among them, the outer side of the precipitation tank 1 is provided with a support leg 13 through a fixing seat 12, and a foot pad is provided at the bottom of the support leg 13. The support and fixation of the precipitation device are realized by the support leg 13, so that it can be stably placed in a suitable place, and the foot pad plays an anti-slip role, thereby improving the stability of the precipitation device.

[0029] The outer diameter of the filter element 9 is the same as the inner diameter of the exhaust pipe 8, and the filter element 9 is slidably sleeved inside the exhaust pipe 8. The same inner diameter of the filter element 9 and the exhaust pipe 8 can ensure that the filter element 9 will not tilt when the filter element 9 is slidably installed inside the exhaust pipe 8, thereby ensuring the stable installation of the filter element 9.

[0030] Working principle: the raw materials and reaction reagents for white carbon black production are fed into the precipitation kettle 1 through the feed pipe 6 on the sealing cover 2, and the motor 3 drives the stirring blade 5 on the connecting shaft 4 to rotate, thereby accelerating the reaction speed of the raw materials and the reaction reagents in the precipitation kettle 1, so that the raw materials and the reaction reagents are fully mixed and reacted, and then precipitated in the precipitation kettle 1. During the reaction process, the exhaust gas generated by the reaction is discharged through the exhaust pipe 8, and the exhaust gas is filtered by the filter element 9 in the exhaust pipe 8. When the filter element 9 needs to be replaced, it is only necessary to open the positioning component 11, and then the filter element 9 pops out of the exhaust pipe 8 under the ejection action of the ejection component 10, so that the filter element 9 is convenient for maintenance and replacement.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
