Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor for chemical raw materials. Background Art

[0002] A reactor is broadly understood as a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are achieved.

[0003] At present, in the production process, sampling is required during the operation of the reactor to monitor the components in real time for real-time adjustment and monitoring. However, the sampling device is mostly set on the top of the reactor and samples are taken through the sampling tube, which affects the stirring inside the reactor and limits the style of the stirring structure. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a chemical raw material reactor with a simple structure, multi-point sampling, and convenient operation.

[0020] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0021] like Figure 1-3 As shown, a reactor for chemical raw materials includes a reactor body 1 and a reactor cover 2. The reactor body is connected to the reactor cover to form a reactor device. A stirring shaft is provided in the reactor body, and a plurality of stirring rods (not shown) are connected to the stirring shaft. A reduction motor is fixedly installed on the top of the reactor cover through a motor bracket. The output shaft of the reduction motor passes through the reactor cover and is fixedly connected to the stirring shaft through a coupling.

[0022] A sampling tube 11 is provided on the outside of the reactor body. Both ends of the sampling tube are closed and a sampling cavity is provided inside the sampling tube. At least two connecting tubes 12 are installed on the sampling tube. The connecting tubes have channels that communicate with the sampling cavities of the sampling tubes. One end of the connecting tube is fixedly connected to the reactor body. A sampling port is opened on the reactor body facing the channel of the connecting tube. A sampling port sealing structure is installed on the connecting tube.

[0023] A manifold 13 is provided at the lower end of the sampling tube. Both ends of the manifold are closed. The manifold has a reflux cavity. The manifold is connected to the sampling tube through a branch pipe 14. Both ends of the branch pipe are connected to the sampling cavity and the manifold cavity respectively. The manifold is connected to the outside with an outlet flow channel 15, and an outlet solenoid valve 16 is installed on the outlet flow channel.

[0024] In this way, the reactor body is connected to the reactor cover to form a reactor device. A heater and a temperature controller are provided in the reactor device. The reduction motor drives the stirring shaft and stirring blades to rotate to stir and mix the materials in the reactor.

[0025] When sampling is required, the outlet solenoid valve is opened, the sampling port sealing structure is opened, and the material in the reactor body enters the sampling cavity of the sampling tube through the sampling port, and then is collected into the confluence cavity of the confluence pipe through the branch pipe, and finally flows out through the outlet flow channel to complete the sampling.

[0026] The sampling tube is arranged on one side of the reactor body to avoid interference between the sampling process and the stirring shaft and stirring rod. At the same time, at least two connecting tubes are provided to improve the sampling efficiency and sampling uniformity, which can better meet the use requirements.

[0027] During implementation, the sampling port sealing structure includes a hydraulic cylinder 15 fixedly mounted at one end of a connecting pipe. The cylinder rod of the hydraulic cylinder passes through the passage and is fixed with a plug 16. The reactor body has a countersunk hole in communication with the sampling port, facing the plug. The diameter of the countersunk hole is larger than that of the sampling port. The hydraulic cylinder drives the plug to move. When the sampling port needs to be sealed, the cylinder rod of the hydraulic cylinder retracts, driving the plug into the countersunk hole. Since the diameter of the countersunk hole is larger than that of the sampling port, the plug seals the sampling port.

[0028] During implementation, a sealing gasket is fixed on the countersunk hole facing the plug, thereby improving the sealing effect of the plug on the sampling port.

[0029] During implementation, backwash pipes 17 are connected to both ends of the manifold. These backwash pipes have backwash channels, and backwash ports are located at both ends of the manifold, facing the channels. A backwash solenoid valve 18 is installed on the channels. When flushing the sampling tubes, a hydraulic cylinder extends the plug, opening the sampling ports. The backwash solenoid valve opens, allowing backwash water to enter the backwash pipe. The backwash water then flows through the backwash channels, branch pipes, and sampling chamber, into the reactor body, and is finally discharged through the discharge port at the bottom of the reactor body. This allows for the use of different materials while maintaining their purity.

[0030] During implementation, three connecting pipes are provided and are respectively arranged at both ends and the middle of the sampling pipe, so as to improve the accuracy of sampling.

[0031] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
