DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] As shown in Figure 1 and Figure 2 The utility model provides a kind of technical scheme of pipe reactor of facilitating feeding, including feeding pipeline 2, butt flange 1 is fixedly installed at one end of feeding pipeline 2, butt joint 3 is opened in feeding pipeline 2, filter plate 4 is equipped in feeding pipeline 2, feeding mechanism 5 is connected at butt joint 3, stirring mechanism 6 is equipped in feeding pipeline 2 and located at one side of filter plate 4, by the cooperation of feeding mechanism 5 and stirring mechanism 6, uniform feeding can be realized, and raw materials are prevented from being blocked in pipeline.

[0022] As shown in Figure 2 and Figure 3 Feeding mechanism 5 includes vertical conveying pipe 507 fixedly installed in butt joint 3, horizontal conveying pipe 506 is fixedly installed on the upper end of vertical conveying pipe 507, driving motor 503 is fixedly installed at one end of horizontal conveying pipe 506, driving shaft 502 is rotatably installed in horizontal conveying pipe 506, feeding screw 505 is fixedly installed on driving shaft 502, butt joint gap 504 is opened in horizontal conveying pipe 506, feeding hopper 501 is fixedly installed at butt joint gap 504, coupling is equipped at the output end of driving motor 503, and driving shaft 502 is fixedly installed on the output end of driving motor 503 through coupling.

[0023] Specifically, in the process of conveying the liquid raw material, the driving motor 503 can be started first. Once the driving motor 503 is activated, it will start to drive the driving shaft 502 connected thereto to rotate. With the rotation of the driving shaft 502, it will further drive the feeding screw 505 matched therewith to start rotating. When the feeding screw 505 rotates, it will effectively convey the solid raw material in the feeding hopper 501 into the feeding pipe 2. Once the solid raw material enters the feeding pipe 2, it will be in full contact with the liquid raw material and start to dissolve. With the dissolution of the solid raw material in the liquid raw material, the two will gradually mix evenly, and finally the mixture is smoothly conveyed into the tubular reactor, where they will participate in the subsequent chemical reaction process.

[0024] As shown in Figure 2 and Figure 4 , the stirring mechanism 6 comprises a mechanism housing 601 fixedly installed on the feeding pipe 2, a transmission shaft 602 rotatably installed in the mechanism housing 601, and a movable hole 606 formed at the upper and lower edges of the mechanism housing 601.

A retainer is provided in the mechanism housing 601, and the transmission shaft 602 is movably installed in the mechanism housing 601 through the retainer.

[0025] Specifically, when the solid raw material is accumulated on one side of the filter plate 4, the driving shaft 502 can drive the transmission shaft 602 to rotate. During the rotation of the transmission shaft 602, the movable shaft 604 is further driven to rotate. Under the driving force of the rotation of the movable shaft 604, the stirring paddle 605 starts to rotate on one side of the filter plate 4. This rotating motion can effectively stir the solid raw material accumulated on one side of the filter plate 4, promote the mixing between the solid raw material and the liquid raw material, and thus accelerate the dissolution process of the solid raw material in the liquid. Through such stirring action, the possibility of clogging of the raw material in the pipe can be significantly reduced, ensuring smooth progress of the entire production process.
