Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor with a novel manhole structure. Background Art

[0002] According to the characteristics of the processed materials, some reactors need to use titanium or titanium composite plates, which have good corrosion resistance and high heat resistance. At this time, the manholes for maintenance also need to be made of titanium. The full titanium manhole has high cost and low strength.

[0003] Because titanium and stainless steel or carbon steel cannot be directly welded, conventional titanium composite plate reactors, the manhole flanges and blind plates for maintenance manholes are made of composite plates, which are relatively expensive. Such manholes are expensive and the order cycle of composite plates is long. Therefore, improvements are needed.

[0004] Conventional reactor equipment with bottom support is generally difficult to stir at the bottom of the bottom support, and there is a dead point. When the material does not move, the bottom discharge port is easily blocked when there are solid materials in the material. For this type of bottom discharge structure, if there are solids in the material, the solids will be deposited due to the immobility of the material under the bottom support, blocking the discharge port and affecting the discharge effect. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, the utility model provides a reaction kettle with a novel manhole structure which is simple in structure and convenient to use.

[0006] The utility model is realized through the following technical solutions:

[0008] A sealing installation plate is welded at the center of the top cover, a supporting protective tube is fixed on the sealing installation plate, and the coupling of the reduction motor is located inside the supporting protective tube; a maintenance manhole is installed on the top cover, and a sealing cover is installed in the maintenance manhole;

[0009] The manhole includes a cylindrical connecting pipe, a flange and a blind plate. The connecting pipe is fixed on the top cover, the flange is fixed on the upper end of the connecting pipe, the blind plate is fixed to the flange by bolts, and a sealing gasket is sandwiched between the blind plate and the flange.

[0010] The blind plate, connecting pipe and flange are all made of carbon steel; a titanium plate is inlaid on the inner side of the blind plate through a number of rivets, and a titanium liner ring is sleeved on the inner side of the connecting pipe. The upper end of the liner ring has an outward horizontal flange, which rests on the flange. The sealing gasket is located between the flange and the titanium plate. The lower end of the liner ring extends into the hole of the top cover and is welded to the titanium material of the inner wall of the top cover.

[0011] The manhole for maintenance is also used as the material inlet.

[0012] A stirring shaft bottom support frame is fixedly installed at the lower end of the kettle body, and the lower end of the stirring shaft is installed on the stirring shaft bottom support frame through a bearing; a propulsion stirring blade is installed at the lower end of the stirring shaft, and the propulsion stirring blade is located inside the stirring shaft bottom support frame, close to the discharge port of the kettle body.

[0013] A number of triangular ear seats are also fixed on the outside of the kettle body, and a horizontal fixing plate is welded at the bottom of the ear seat. The horizontal fixing plate is used to connect the frame through bolts, so as to fix the kettle body on the frame.

In the inherent mode, the stirring paddle of the reactor lengthens the shaft head at the bottom of the stirring shaft, and adds a small push-type stirring paddle (downward pressure mode) at the bottom of the stirring shaft bottom support frame, which not only makes the stirring dead point at the bottom of the bottom support during the stirring process to prevent the accumulation of materials at the bottom, but also the stirring downward pressure can promote the discharge of materials, significantly speeding up the discharge speed.
