Abstract

The utility model relates to a bubbling blending device, which relates to the technical field of the blending of a reaction kettle, and particularly relates to the technical field of the bubbling blending. The bubbling blending device comprises a reaction kettle, a bubbling pipe, a gas inlet valve, a gas inlet pipe, a material discharging valve, a material discharging pipe and a bubbling hole; and the bubbling blending device is characterized in that the gas inlet pipe is connected with the bubbling pipe through the gas inlet valve and enters the reaction kettle from the bottom side part of the reaction kettle, the bottom part of the reaction kettle is connected with the material discharging pipe, the material discharging pipe is provided with the material discharging valve, and the bubbling pipe is a reduced pipe of a necked group with N bubbling holes. The bubbling blending device has characteristics of simplicity in structure, convenience in installation, maintenance and washing, long acting time and low power consumption.

Description

The bubbling agitating device

Technical field

The utility model relates to reactor stirring technique field, is bubbling stirring technique field specifically.

Background technology

Liquid-solid in the Chemical Manufacture, gas-solid reaction has many reactions to carry out in reactor, state patent CN201887067U discloses bubbling stirring-type liquid-replenishing device with texturing tank, but its complex structure, adopt the form of square tube bubbling, the initial velocity direction of stirred fluid is vertically upward and horizontal direction, but the reactor bottom just forms easily and stirs the dead angle, vertically upward venthole particularly, the initial velocity direction is vertically upward, and the buoyancy direction of bubble also is vertically upward, so interface on the very fast disengaging reaction system of bubble, mixing time is short, and power consumption is large.Chinese patent CN102078778A is simple in structure, and clean and maintenance is convenient, but exists equally the reactor bottom to be prone to the problem that stirs the dead angle.

Summary of the invention

The deficiency that exists in order to overcome above-mentioned prior art, the purpose of this utility model be to provide a kind of simple in structure, easy for installation, be convenient to safeguard and cleaning, the low bubbling agitating device of long action time power consumption.

For achieving the above object, the utility model by the following technical solutions: this device comprises: reactor, bubbling pipe, intake valve, air inlet pipe, material dump valve, material discharge pipe, bubble holes; The feature of this utility model comprises, air inlet pipe is by intake valve and connect bubbling pipe and enter reactor by the Polycondensation Reactor and Esterification Reactor sidepiece, reactor bottom attachment material discharge pipe, the material dump valve is housed on the material discharge pipe, and described bubbling pipe is the reducer pipe that has N bubble holes on the reducer pipe by thin change group.

Beneficial effect: simple in structure, easy for installation, be convenient to maintenance and cleaning, the stirring action time is long, power consumption is low.

Description of drawings

Fig. 1: bubbling agitating device schematic diagram;

Fig. 2: A-A profile;

Fig. 3: B-B profile.

Among the figure: 1 reactor, 2 bubbling pipes, 3 intake valves, 4 air inlet pipe, 5 material dump valves, 6 material discharge pipes, 21 bubble holes.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

Embodiment

The bubbling agitating device comprises: 1 reactor, 2 bubbling pipes, 3 intake valves, 4 air inlet pipe, 5 material dump valves, 6 material discharge pipes, 21 bubble holes; Air inlet pipe is by intake valve and connect bubbling pipe and enter reactor by the Polycondensation Reactor and Esterification Reactor sidepiece, and reactor bottom attachment material discharge pipe is equipped with the material dump valve on the material discharge pipe, and described bubbling pipe tube wall periphery is a distribution N bubble holes evenly.

First the material that reacts is added in the reactor during use, open air compressor machine, open intake valve, compressed air enters bubbling pipe by air inlet pipe, bubble goes out gas agitating by the equally distributed N of a bubbling pipe tube wall periphery bubble holes to reaction mass, outgassing direction is the direction around the bubbling pipe periphery, eliminate and stir the dead angle, on the lower side the direction bubble holes can make bubbling the initial velocity direction on the lower side, only gradually break away from reaction system by the buoyancy of bubble, therefore, the initial velocity direction is the mixing time of the bubble that makes progress of the mixing time＞speed of bubble on the lower side, thereby reach the raising stirring efficiency, the purpose of Reduction of power consumption.

The above only is preferred embodiment of the present utility model, and all equivalences of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.

Claims

1. the bubbling agitating device comprises: reactor, bubbling pipe, intake valve, air inlet pipe, material dump valve, material discharge pipe, bubble holes; The bubbling agitating device is characterized in that, air inlet pipe is by intake valve and connect bubbling pipe and enter reactor by the Polycondensation Reactor and Esterification Reactor sidepiece, reactor bottom attachment material discharge pipe, the material dump valve is housed on the material discharge pipe, and described bubbling pipe is the reducer pipe that has N bubble holes on the reducer pipe by thin change group.
