Abstract

A reaction vessel stirrer blade belongs to the technical field of chemical machinery, and is used for stirring of materials in a reaction vessel; the technical scheme is that: the blade comprises two parts of a curved blade and a planar blade; the curved blade is a propeller-type curved blade manufactured by bending a straight steel plate; one end of the curved blade is connected with a stirring shaft; the end edge of the curved blade at the joint has an inclined included angle with the horizontal plane; a central vertical axis of the curved blade is located on the horizontal plane; the center part of the other end of the curved blade is connected with the planar blade; the planar blade is perpendicular to the horizontal plane, and the central vertical axis of the planar blade is located on the horizontal plane. The reaction vessel stirrer blade which adopts the structure and shape has central area stirring capability, a fluid lifting function, and strong outer-ring stirring capability; precipitates in the reaction vessel can be mixed with a mixed solution completely with the flow of the liquid; because of the strong stirring capability and uniform mixing, the reaction inside the mixed solution is complete. The utility model is simple in manufacturing, and is especially applicable to reaction vessels with precipitate generation.

Description

A kind of agitated reactor mixing arm

Technical field

The utility model relates to a kind of agitating device that is used for agitated reactor, belongs to the chemical mechanical equipment technical field.

Background technology

Agitated reactor is the utensil that carries out chemical reaction in the commercial production, is commonly used in fields such as pharmacy, chemical industry.In order to react fully, usually in agitated reactor, add mixing plant.In the agitated reactor that has deposition to generate, both needed evenly to stir, need dull thing granule along with liquid flow again, therefore need to accomplish the agitating device of these two kinds of functions.Normally used agitator all is single vertical bar steel plate or anchor formula in agitated reactor at present, and structure and shape are all fairly simple, and convection cell does not have castering action, deposits easily when having deposition to generate, and be unfavorable for precipitating the reaction that continues with mixed liquor, and power consumption is higher; And with single axial-flow type stirring vane, the stirring capacity of outer ring liquid is not enough, and cost is very high.Therefore, the agitator that in agitated reactor, uses at present all can not reach this requirement, is necessary to develop the agitating device of the agitated reactor use that is applicable to that deposition generates.

The utility model content

The utility model technical problem to be solved provides a kind of strong agitated reactor mixing arm of central area stirring capacity, fluid enhanced feature and outer ring stirring capacity that has.

The technical scheme that solves the problems of the technologies described above is:

A kind of agitated reactor mixing arm, it is made up of curved surface bucket and plane blade two parts, and curved surface bucket is the propeller type curved surface bucket that straight steel plate bending is made; One end of curved surface bucket is connected with shaft; The curved surface bucket end limit and the horizontal plane of junction have slanted angle, and the center longitudinal axis of curved surface bucket is positioned on the horizontal plane, and the center of the other end of curved surface bucket is connected with plane blade; Plane blade is perpendicular to horizontal plane, and its center longitudinal axis is positioned on the horizontal plane.

Aforesaid reaction vessel mixing arm, said curved surface bucket end limit that is connected with shaft and horizontal plane angle β are 40 °-60 °, and curved surface bucket end limit that curved surface bucket is connected with plane blade and horizontal plane angle α are 15 °-25 °.

The aforesaid reaction vessel mixing arm; Said shaft has the base of connection with the junction of curved surface bucket; There is flanging on the curved surface bucket end limit that is connected, and the screw of arrangement is arranged on the flanging, and connecting bolt is fastenedly connected curved surface bucket through screw with the base that is connected on the shaft.

Adopt the agitated reactor mixing arm of this structure and shape; It is strong to have central area stirring capacity, fluid enhanced feature and outer ring stirring capacity; Can make to precipitate in the agitated reactor and fully mix with mixed liquor with liquid flow; Because stirring capacity is strong, mixes, and can make the mixed liquor internal-response abundant.The utility model is made simple, is particularly suitable for the agitated reactor use that deposition generates.

The specific embodiment

The utility model is made up of curved surface bucket 2 and plane blade 1 two parts.

Show among the figure; Curved surface bucket 2 is the propeller type curved surface bucket that straight steel plate bending is made; One end of curved surface bucket 2 is connected with shaft 6; The curved surface bucket end limit 4 and the horizontal plane of junction have slanted angle, and the center longitudinal axis of curved surface bucket 2 is positioned on the horizontal plane, and the center of the other end of curved surface bucket 2 is connected with plane blade 1.Curved surface bucket 2 is responsible for stirring and the liquid enhanced feature at inner ring.

The curved surface bucket end limit 4 and the horizontal plane angle β that are connected with shaft 6 are 40 °-60 °, and curved surface bucket end limit 3 and horizontal plane angle α that curved surface bucket 2 is connected with plane blade 1 are 15 °-25 °.

Show among the figure that plane blade 1 is perpendicular to horizontal plane, its center longitudinal axis is positioned on the horizontal plane.End in that plane blade 1 is connected with curved surface bucket 2 is fluted; Depth of groove 10mm-15mm; The curved surface bucket 2 that processes is inserted in the groove of plane blade 1; The adjustment curved surface bucket is met to fluid end limit 5 and the curved surface bucket end limit 3 that links to each other with plane blade 1, and curved surface bucket is met to fluid end limit 5 maintenance levels, forms integral blade through welding.Plane blade 1 has very strong outer ring stirring capacity.

Show among the figure that shaft 6 has the base of connection with the junction of curved surface bucket 2, there is flanging on the curved surface bucket end limit 4 that is connected, and the screw of arrangement is arranged on the flanging, and connecting bolt is fastenedly connected curved surface bucket 2 through screw with the base that is connected on the shaft 6.

The utility model material decides according to liquid in the agitated reactor, if there is not corrosivity, can make with general steel plate, needs acid-alkali-corrosive-resisting stainless steel or macromolecular material to make if be corrosive.

Through above enforcement, can make deposition abundant and mixed liquor reaction in the agitated reactor, and, mix, so the mixed liquor internal-response is abundant because stirring capacity is strong with liquid flow.
