Description

The wet method synthesis reactor

Technical field:

The utility model relates to a kind of superfine powdery material and nano-powder material synthetic reaction equipment, particularly a kind of wet method synthesis reactor.

Background technology:

The wet method synthesis reactor that wet method prepares fine powder body material and nano material is used for the synthetic reaction that multiple metal such as aluminium oxide, zinc oxide, zinc powder, nickel powder, cobalt powder, nickel hydroxide and compound powder material thereof generate.Existing wet method synthesis reactor is mainly by in the drum shaped reaction groove guide shell, agitator and transmission device thereof being housed, around reactive tank heater being housed outward forms, existing wet method synthesis reactor guide shell upper end closed is fixed on groove and covers, only fluid is entered in the guide shell at a direction opening, the conductor weak effect, the setting height(from bottom) of existing agitator in reactive tank fixed, and be unadjustable, and the transmission device rotating speed of agitator adjustable speed scarcely; The heater of existing wet method synthesis reactor is to adopt steam heater, is difficult to accurately control temperature and quick adjustment temperature, and the interlayer cover of steam heater belongs to pressure vessel, manufacturing, maintenance difficult.Existing wet method synthesis reactor can not satisfy various powder body materials and generate the granularity of product and the demand of shape because reaction conditions such as reaction temperature, mixing speed are difficult to control.

Summary of the invention:

The purpose of this utility model is to overcome the above-mentioned defective of existing wet method synthesis reactor, designs a kind of reaction temperature, and reaction conditions such as solution mixing speed are easy to regulate, and are suitable for the wet method synthesis reactor of the powder body material of preparation different grain size and shape.

Technical solution of the present utility model is the wet method synthesis reactor, mainly by in the drum shaped reaction groove guide shell, agitator and transmission device thereof being housed, around reactive tank heater being housed outward and forming:

(1) the guide shell upper/lower terminal is uncovered, is loaded in the reactive tank via coupling mechanism that can upper and lower adjusting position;

(2) agitator is loaded on reactive tank drum top via lowering or hoisting gear; Agitator connects with buncher is coaxial;

(3) on the reactive tank drum inwall, the shelves stream plate of some settings of circumference uniform distribution;

(4) heater is that electric heating coil and heat-insulation layer are formed.

The agitator lowering or hoisting gear is made up of worm gear snail pavilion mechanism and pinion and rack, worm-and-wheel gear is installed on the gear-box of reactive tank top cover, the worm screw that ribbon gymnastics is made handle is agitator lift adjustment action bars, worm gear and gears engaged, the wheel and rack engagement, tooth bar is connected on the coupling sleeve of agitator.The coupling mechanism of guide shell and reactive tank is to connect firmly long bolt on the guide shell outer wall, the upper end is loaded on the reactive tank top cover through nut, the guide shell outer wall with connect firmly on the reactive tank cylindrical wall several uniform cantilevers through Bolt Connection, the Bolt Connection hole is for vertically to strip hole.

Description of drawings:

Fig. 1 is a wet method synthesis reactor structure positive view;

Fig. 2 is an agitator lifting device structure schematic diagram;

The specific embodiment:

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing.

The wet method synthesis reactor, referring to accompanying drawing 1, it is that guide shell 2 is installed in drum shaped reaction groove 1, connect firmly long bolt 5 on guide shell 2 outer walls, long bolt 5 upper ends are loaded on reactive tank 1 top cover 6 through nut, can regulate on the guide shell, upper/lower positions, guide shell 2 outer walls with connect firmly on reactive tank 1 cylindrical wall several uniform suspended wall 3 through Bolt Connection, Bolt Connection connects hole 4 for vertically to strip hole, be convenient to, downward modulation is stream tube position successively, agitator 7 passes guide shell 2, and the impeller shaft of agitator 7 upper end connects with lowering or hoisting gear 8 on reactive tank 1 top cover 6, can regulate agitator 7 on, upper/lower positions.Agitator 7 connects through coupling sleeve 10 and bearing 11 with frequency control motor 9, can regulate agitator 7 mixing speeds.Speed adjustable range is 100rpm-300rpm.

Lowering or hoisting gear 8, referring to accompanying drawing 2, it is made up of worm-and-wheel gear and pinion and rack, and worm-and-wheel gear is installed on the gear-box of installing on reactive tank 1 top cover 6 20, and the worm gear pole 17 that ribbon gymnastics is made handle is the action bars of regulating agitator 7 liftings.Worm gear 18 and gear 16 engagements, gear 16 and tooth bar 19 engagements, tooth bar 19 connects firmly on coupling sleeve 10, is integrated, and coupling sleeve 10 connects with agitator 7 impeller shafts through bearing 11.

The shelves stream plate 12 of some settings of circumference uniform distribution on the reactive tank 1 drum inwall is referring to accompanying drawing 1.

Around reactive tank 1 cylinder heater 13 is installed outward, heater 13 is that electric heating coil and heat-insulation layer are formed, and is close to the cell wall shell, and compact dimensions does not account for volume, and is convenient to regulate temperature, insulation and heat exchange.
