Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a catalyst precipitation reactor. Background Art

[0002] The reactor is a comprehensive reaction vessel. The design of the reactor structure, function and accessories is based on the reaction conditions. From the initial feeding-reaction-discharging, the pre-set reaction steps can be completed with a high degree of automation, and the important parameters such as temperature, pressure, mechanical control (stirring, blasting, etc.), reactant / product concentration, etc. during the reaction process are strictly regulated. Its structure is generally composed of a kettle body, a transmission device, a stirring device, a heating device, a cooling device, and a sealing device.

[0003] In the process of preparing catalysts by precipitation method, a reactor is required to mix the raw materials. However, when using the existing catalyst precipitation reactor, personnel cannot understand the processing conditions inside the reactor. If the material is not completely processed and the personnel opens the discharge pipe, a large amount of material will be wasted. If there is a problem during processing, the personnel will not be able to know it to the outside world. Therefore, in order to solve the above problems, the prior art uses a suction pump to extract the material in the reactor for observation.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The present invention provides Figure 1-3 The catalyst precipitation reactor shown comprises an outer tank 1 and an inner tank 2. The inner tank 2 is arranged inside the outer tank 1.

The raw materials are introduced into the inner tank 2 through the feed pipe 32 for easy processing. The processed raw materials can be discharged through the discharge pipe 33 to complete the entire catalyst processing feeding and discharging process.

[0034] Moreover, during the processing, it is necessary to stir the raw materials inside the kettle body tank 2. As shown in FIG5 , the present invention further includes a stirring mechanism installed inside the kettle body tank 2. Specifically, the stirring mechanism includes a stirring shaft 3 installed inside the kettle body tank 2. The top end of the stirring shaft 3 penetrates the kettle body tank 2 and the kettle body tank 1 and extends out of the top of the kettle body tank 1. The top end of the stirring shaft 3 is movably connected to the kettle body tank 2 and the kettle body tank 1 through a sealed bearing. The bottom end of the stirring shaft 3 is movably connected to the inner wall of the kettle body tank 2 through a bearing.

In addition, the mechanical seal 4 set at the top of the stirring shaft 3 can also improve the overall sealing performance.

[0036] In addition, during the stirring process of the raw materials, the raw materials need to be cooled or heated depending on the type of catalyst, such as Figure 4 and 6 As shown, a spiral cold pipe 7 and a heat pipe 8 are provided between the outer tank 1 of the kettle body and the outer tank 2 of the kettle body. The cold pipe 7 flows with materials for cooling the inner tank 2 of the kettle body, and the heat pipe 8 flows with materials for heating the inner tank 2 of the kettle body. By injecting a low-temperature fluid into the cold pipe 7, the heat of the materials in the inner tank 2 of the kettle body can be absorbed during the reaction process to achieve the purpose of cooling. Moreover, by injecting a high-temperature fluid into the heat pipe 8, the inner tank 2 of the kettle body can be heated.

[0037] During the reaction, in order to facilitate the staff to observe the reaction of the raw materials in the tank 2 in the kettle, the staff needs to take out some of the raw materials for observation.

Figure 5 and 8As shown, a raw material reflux mechanism is provided inside the observation box 18, and the raw material reflux mechanism extends out of the top of the observation box 18. Specifically, the raw material reflux mechanism includes a partition 22 installed inside the observation box 18, and a second connecting pipe 23 is fixedly provided inside the partition 22. The bottom end of the second connecting pipe 23 passes through the outer tank 1 of the kettle body and the inner tank 2 of the kettle body and extends into the inner tank 2 of the kettle body. The second connecting pipe 23 is connected to the inner tank 2 of the kettle body. A piston plate 24 is provided on the top of the partition 22, and two threaded rods 25 are fixedly provided on the top of the piston plate 24. The outer end of the threaded rod 25 is threadedly connected with a hollow rod 26. The top end of the hollow rod 26 passes through the observation box 18 and extends out of the top of the observation box 18.

The third solenoid valve can prevent the raw materials drawn into the observation box 18 from flowing downward through the second connecting pipe 23, and can also prevent the raw materials in the inner tank 2 of the kettle from entering the observation box 18 through the second connecting pipe 23;
