Description

TECHNICAL FIELD

[0001] The present application relates to the field of reaction kettles, in particular to a reaction kettle with a lifting device. BACKGROUND

[0002] A reaction kettle is a device for realizing a chemical reaction process, which is widely used in the fields of chemical industry, pharmaceutical industry, etc. It can realize liquid reaction process and multiphase reaction process such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid. The design and manufacture of the reaction kettle need to be based on relevant technical standards to ensure that it can meet the process requirements of heating, evaporation, cooling, and low-speed mixing reaction functions.

[0003] When the reaction kettle involves solid participation, the density of the solid is greater than that of the liquid, which easily causes the solid to always be on the bottom wall of the reaction kettle, resulting in the inability of the fixed side abutting the bottom wall of the reaction kettle to contact the liquid. Moreover, the stirring device in the reaction kettle is difficult to drive the solid to separate from the bottom wall of the reaction kettle, and the working efficiency of the reaction kettle in processing solid-liquid reaction is not high. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the working efficiency of the reaction kettle in processing solid-liquid reaction, the present application provides a reaction kettle with a lifting device.

[0005] The present application provides a reaction kettle with a lifting device, which adopts the following technical solution:

[0006] The reaction kettle with a lifting device comprises a kettle body and a lifting assembly. The lifting assembly comprises a lifting motor, a guide pipe, and an auger. The guide pipe is coaxially arranged with the kettle body. One end of the guide pipe is arranged on the inner bottom wall of the kettle body. The guide pipe is provided with a through hole for the material to enter. The auger is coaxially arranged with the guide pipe. The auger is rotationally connected in the kettle body. The lifting motor is used to drive the rotation of the auger.

[0007] By adopting the above technical solution, when the solid and liquid materials are reacted, the solid materials will accumulate on the inner bottom wall of the kettle body under the action of gravity. The solid materials enter the guide pipe through the through hole. The lifting motor drives the rotation of the auger. The auger drives the solid materials to lift along the length direction of the guide pipe until the solid materials separate from the upper end surface of the guide pipe. At this time, the solid materials re-enter the liquid materials. At this time, the circumferential side of the solid materials is in contact with the liquid materials, which accelerates the reaction speed and improves the working efficiency of the reaction kettle.

[0008] Optionally, the outer side wall of the guide pipe is provided with a guide plate. The guide plate extends circumferentially along the outer side wall of the guide pipe. The height of the guide plate gradually decreases away from the guide pipe.

[0009] By adopting the technical scheme, the solid material falls from the upper end surface of the guide pipe to the outside of the guide pipe, contacts the guide plate, and slides along the inclined direction of the guide plate, so that the solid material falls without adhering to the outer side wall of the guide pipe, thereby better contacting the liquid material and improving the reaction speed of the material.

[0010] Optionally, the kettle body is provided with a stirring assembly, the stirring assembly comprises a mounting disc, a stirring blade and a connecting rod, the stirring blade is sleeved on the outer side wall of the guide pipe, the mounting disc is coaxially arranged on the guide pipe, the mounting disc is arranged on the output shaft of the lifting motor, one end of the connecting rod is arranged on the mounting disc, and the other end of the connecting rod is arranged on the stirring blade.

[0011] By adopting the technical scheme, the stirring assembly is used to stir the liquid in the kettle body, so that the liquid in the kettle body is more uniformly mixed with the solid, and the lifting motor drives the mounting disc to rotate through the lifting assembly, the mounting disc drives the stirring blade to rotate through the connecting rod, without the need for an additional power source, which meets the green environmental protection concept.

[0012] Optionally, the outer side wall of the guide pipe is provided with an annular groove, the annular groove is in a wave shape, the stirring blade is provided with a matching rod, the matching rod is located in the annular groove, and the connecting rod comprises a sliding rod and a sleeve.

[0013] By adopting the technical scheme, the wave-shaped annular groove cooperates with the matching rod on the stirring blade to achieve the effect of up-and-down sliding of the stirring blade during rotation, thereby improving the stirring range of the stirring blade, and the connecting rod comprises a sliding rod and a sleeve, and the sliding rod is slidably connected to the sleeve, which is reasonable in structure.

[0014] Optionally, the matching rod is rotatably connected with a roller, and the roller abuts against the inner side wall of the annular groove.

[0015] By adopting the technical scheme, the roller is located in the annular groove, and the matching rod moves in the annular groove through the roller during rotation of the stirring blade, so that the roller reduces the friction with the annular groove and reduces the output torque required by the lifting motor.

[0016] Optionally, the guide plate is provided with a scraper, and the scraper abuts against the inner side wall of the kettle body.

[0017] By adopting the technical scheme, part of the solid material is in a powder form, the powder-shaped material is easy to adhere to the inner side wall of the kettle body, the scraper is used to scrape off the material adhering to the inner side wall of the kettle body, and the utilization rate of the powder-shaped material is improved.

[0018] Optionally, the stirring blade is provided with a through hole.

[0019] By adopting the technical scheme, the through hole is used for liquid material flow, the flow speed of the liquid material contacted by the stirring blade is changed, the turbulent flow of the liquid material in the kettle body is facilitated, and the reaction speed of the material is improved.

[0020] Optionally, the kettle body is provided with an observation window for facilitating observation of the inside.

[0021] By adopting the technical scheme, the observation window facilitates observation of the reaction requirement in the kettle body by the staff.

[0022] To sum up, the application has at least one of the following beneficial technical effects:

[0023] 1. The lifting assembly is used for lifting the solid material in the kettle body, the solid material falls from the upper end surface of the guide pipe, and the solid material is fully contacted with the liquid material during the falling process, and the reaction is sufficient;
