[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figs. 1-3 As shown, this utility model discloses a reactor installation structure to reduce weighing errors, including a reactor 1 and an elastic tube 7. A reactor suspension beam 2 is provided in the middle of the reactor 1, and the reactor suspension beam 2 is supported on a weighing module 3. The weighing module 3 adopts a cantilever beam load cell, and the weighing module 3 monitors the overall weight of the reactor 1. Using the weighing module 3 to monitor the overall weight of the reactor 1 and then calculate the accuracy of weighing and batching is a conventional technology.

[0025] Automatic control valves 8 are installed on the top connecting pipe 4, the bottom connecting pipe 6, and the jacket connecting pipe 5 of the reactor.

[0026] The upper part of reactor 1 is connected to four reactor top connecting pipes 4, the lower part of reactor 1 is connected to reactor bottom connecting pipes 6, and the outer jacket of reactor 1 is connected to reactor jacket connecting pipes 5. The reactor top connecting pipes 4, reactor bottom connecting pipes 6 and reactor jacket connecting pipes 5 are all equipped with horizontally arranged transverse pipes, and elastic pipes 7 are installed on the transverse pipes. The elastic pipes 7 are installed on the horizontal transverse pipe sections of all reactor top connecting pipes 4, reactor bottom connecting pipes 6 and reactor jacket connecting pipes 5.

[0027] The elastic tube 7 includes an internal metal corrugated tube 701 and a metal protective mesh 704 fitted on the outside of the metal corrugated tube. The wall of the metal corrugated tube 701 is provided with multiple corrugated structures that are not on the same axis as the metal corrugated tube. The spacing of the corrugated structures in the middle of the metal corrugated tube is smaller than the spacing at the beginning and end.

[0028] The corrugated structure includes corrugated protrusions 705 and corrugated grooves 706. The corrugated grooves 706 are formed by connecting corrugations inside the metal bellows 701, and the corrugated protrusions 705 are formed on the outside of the metal bellows 701.

[0029] The spacing of the corrugated grooves 706 in the middle section of the metal bellows 701 is smaller than that at the beginning and end of the metal bellows 701. This is to ensure that the bending radius of the metal bellows 701 in the middle section is smaller than that at the beginning and end of the metal bellows 701. The small spacing in the middle and the large spacing on both sides of the bellows ensure the bending effect, while the large spacing ensures the strength of the pipe. This saves the cost of the metal bellows 701 and ensures the strength of the pipe, making the overall bending effect of the elastic pipe 7 better and reducing the impact of the pipe on the weighing of the reactor 1 to a greater extent.

[0030] Both ends of the metal corrugated pipe 701 and the metal protective mesh 704 are welded and fixed to the joint 702. The end diameter of the joint 702 is larger than the pipe body diameter of the joint 702. The pipe body of the joint 702 is fitted with a flange 703, and the pipe is connected by the flange 703 and bolts.

[0031] This invention adds a horizontal pipe section to the pipeline connected to the reactor 1, with a flexible connection in the middle of the horizontal pipe, which greatly improves the accuracy of the reactor's load-bearing capacity. During feeding, the automatic control valves 8 of all pipelines connecting the reactor jacket 5 are closed to maintain the stability of the weighing module 3. The feed valve is then opened, and when the required weight of material is reached, a signal is sent to the feed valve, which then closes.

[0032] This utility model is not limited to the above-described embodiments. Anyone should know that any structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
