Description

Technical Field

[0001] The utility model belongs to the technical field of chemical machinery and equipment, and in particular relates to a reaction kettle for preventing gas leakage. Background Art

[0002] In chemical production and related industrial fields, reactors are important chemical reaction equipment, and their sealing performance plays a vital role in ensuring the safety, stability and environmental protection of the reaction process. During the chemical reaction process, reactants or products may produce toxic, corrosive or flammable gases. If these gases leak, they will not only cause serious pollution to the environment, but also may cause safety accidents such as explosions or fires.

[0003] Traditional reactors usually use an external motor to drive the stirring shaft through a mechanical transmission device. Although this method can achieve the stirring function to a certain extent, its sealing performance is often subject to many challenges. The external motor drive method requires the stirring shaft to penetrate the reactor body. This design is difficult to seal completely and is prone to leakage points at the interface. In addition, during long-term operation, due to factors such as wear and vibration of the stirring shaft, the sealing performance will gradually decrease, thereby increasing the risk of leakage.

[0004] In order to solve the above problems, in recent years, some new reactor designs have adopted a built-in drive method, that is, the drive mechanism is designed inside the reactor, and the leakage points are reduced by a more tightly sealed structure. This design usually involves complex internal mechanisms to ensure good sealing performance and efficient transmission efficiency. However, even so, the existing technology still has certain limitations, such as insufficient design of the cooling system, low drive efficiency, and difficulties in maintenance and overhaul. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a reactor that prevents gas leakage. It can achieve, through the design of a built-in circulation pump and cooling system, not only ensuring the effective cooling of mechanical parts, but also reducing potential leakage points through improved sealing, thereby providing a safer and more environmentally friendly chemical reaction equipment solution.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A reaction kettle for preventing gas leakage, comprising a bottom bin, a discharge nozzle is arranged at the bottom of the bottom bin, a top bin is connected to the top bin, a sealing member is arranged at the top of the top bin, and a driving assembly is connected to the top of the sealing member;

[0008] The driving assembly comprises a driving chamber, the interior of the driving chamber is rotatably connected to a driving shaft, and the outer side of the driving shaft is provided with a spiral blade;

[0009] The bottom of the driving shaft is connected to a stirring shaft, and the bottom end of the stirring shaft extends into the bottom bin;

[0010] An output pipe and an input pipe are fixedly connected to the outer side of the driving chamber, and the input pipe is located above the output pipe.

[0011] Furthermore, a baffle is fixedly connected to the outer side of the driving shaft, and the baffles are distributed at equal intervals along the length direction of the driving shaft.

[0012] Furthermore, a bearing seat is fixedly connected to the inner top of the driving compartment;

[0013] A bearing is arranged inside the sealing member.

[0014] Furthermore, a sealing seat is provided inside the sealing member, the sealing seat is located below the bearing, and a sealing ring is clamped inside the sealing seat.

[0015] Furthermore, a flange ring is fixedly connected to the outer surface of the bottom opening end of the driving assembly.

[0016] Furthermore, a stirring blade is arranged on the outer side of the stirring shaft.

[0017] Furthermore, a connecting seat is provided at the top of the top bin, and the sealing member is fixed on the connecting seat by screws.

[0018] Furthermore, a first heat-insulating cover is provided on the outer side of the bottom bin, and a second heat-insulating cover is provided on the outer side of the top bin.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The built-in drive and circulating cooling system significantly improves the sealing performance during the chemical reaction process. The built-in drive chamber structure effectively reduces the poor sealing problem caused by external drive, which is common in traditional reactors. This design allows all mechanical rotating parts such as the drive shaft and the stirring shaft to be tightly sealed inside the reactor, greatly reducing environmental pollution and safety risks caused by leakage at the mechanical interface.

[0021] In addition, the reactor is equipped with a circulating pump and corresponding input and output pipes to form a closed coolant circulation system, which effectively manages the heat generated during the reaction process. This not only ensures the stability of the internal temperature of the reactor, but also optimizes the efficiency and safety of the chemical reaction. The addition of the cooling system further ensures the stability and durability of the equipment under high-temperature operating conditions.

[0022] The improvement of the sealing system, especially the use of sealing seats and sealing rings, provides double protection and further strengthens the overall sealing performance of the reactor. This is especially important for handling volatile or harmful chemicals, effectively preventing the escape of toxic gases, thereby protecting the operating environment and the safety of operators.
