Abstract

The utility model discloses a dry mixer. The dry mixer comprises a mixing tank body, wherein feed pipes which are inserted into an inner cavity of the mixing tank body from the lower part of the mixing tank body are connected on the mixing tank body; feeding holes are formed in the bottoms of the feed pipes; a plurality of discharge holes are formed in the feed pipe sections in the mixing tank body from top to bottom; an agitating shaft driven by a power device is connected in the mixing tank body in a rotary manner; agitating vanes are connected on the agitating shaft; a large particle supply pipe is also installed at the upper part of the side wall of the mixing tank body; the lower part of the mixing tank body is in a shape of an inverted cone, and a bottom plate is installed at the lower part; a discharge shaft driven by a discharge motor is connected on the bottom plate in a rotary manner; a plurality of discharge vanes are installed on the discharge shaft; a plurality of discharge holes distributed around the discharge shaft are also formed in the bottom plate; a discharge pipe for bearing materials flowing out of the discharge holes is installed at the bottom of the bottom plate. The dry mixer has the advantages of uniform feed quantity, difficulty in causing feed separation and uniformity in mixing.

Description

A kind of dry type blender

Technical field

The utility model relates to a kind of dry type blender.

Background technology

The dry-mixed mortar tank using at present comprises a tank body, feeder sleeve is positioned at the central interior of tank body, it is outward charging aperture that tank body is stretched out in the lower end of feeder sleeve, material enters to tank body from its upper end, while adopting this structure, entering of small particles material is inhomogeneous, the inhomogeneous charging segregation phenomenon that causes of inlet amount; Moreover discharging opening position, tank body lower end material density strengthens and blanking irregular, cause that dry-mixed mortar mix is not even emanates again.

Utility model content

The technical problems to be solved in the utility model be to provide a kind of inlet amount evenly, be difficult for causing charging segregation phenomenon and the uniform dry type blender of batch mixing.

For solving the problems of the technologies described above, the dry type blender providing comprises batch mixing tank body, its design feature is: on batch mixing tank body, be connected with the feed pipe that inserts its inner chamber from its underpart, the bottom of feed pipe is charging aperture, be positioned on the charging pipeline section of batch mixing tank body and be provided with a plurality of dumping pits from top to bottom, in described batch mixing tank body, be rotatably connected to the shaft being driven by power set, on shaft, be connected with stirring vane, the side wall upper part of described batch mixing tank body is also equipped with bulky grain supply pipe, the bottom of batch mixing tank body is back taper setting and base plate is housed, on base plate, be rotatably connected to by the motor-driven discharging axle of discharging, a plurality of discharge blades are housed on discharging axle, on base plate, be also provided with a plurality of discharge openings that ring discharging axle distributes, the bottom of base plate is equipped with and is accepted the delivery pipe that discharge opening flows out material.

Described feed pipe arranges many and be periphery along batch mixing tank body altogether, and feed pipe is positioned at the inwall setting that the pipeline section of batch mixing tank body is pressed close to batch mixing tank body, and the pipe clamp of clamping feed pipe is also housed on the inwall of batch mixing tank body.

A plurality of discharge blades are arranged and the length of discharge blade diminishes from top to bottom gradually along discharging axle spiral.

Adopt after said structure, the arrogant pellet supply pipe of large granular materials enters batch mixing tank body, by a plurality of dumping pits and deflector, carries out small particles material discharging, and small particles material can draw off from a plurality of dumping pits of arranging up and down simultaneously, thereby discharging is even; Sneak into after small particles material; by startup power set, ordering about shaft rotates; under the stirring of stirring vane; size particles is mixed; during discharging, discharging motor orders about discharging axle and rotates, under discharge blade rotates; effectively prevent from occurring segregation phenomenon in this back taper batch mixing tank body section, make the mixing of materials of outflow even.In sum, the utlity model has inlet amount evenly, be difficult for causing charging segregation and the uniform advantage of batch mixing.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

The specific embodiment

Dry type blender as shown in Figure 1, it comprises batch mixing tank body 1, on batch mixing tank body 1, be connected with the feed pipe 2 that inserts its inner chamber from its underpart, the top of feed pipe 2 is near the inner top of batch mixing tank body 1, the top of feed pipe 2 can adopt worn-out mouthful to arrange, be that small particles material also can be injected in top in batch mixing tank body, the top of feed pipe 2 also can be sealed, whether uncoveredly can control feed pipe 2 tops according to the proportion relation of material and inlet amount, the bottom of feed pipe 2 is charging aperture, be positioned on 2 sections of the feed pipes of batch mixing tank body 1 and be provided with a plurality of dumping pits 6 from top to bottom, on feed pipe 2 below each dumping pit 6, be fixed with the deflector that is tilted to lower setting, in described batch mixing tank body 1, be rotatably connected to the shaft 3 being driven by power set, these power set are the motor 14 that is connected to batch mixing tank body 1 top, the upper end of shaft 3 is connected with the power output shaft power of motor 14 by shaft coupling, the bottom of batch mixing tank body 1 is stretched in the lower end of shaft 3, on shaft 3, be connected with stirring vane 4, stirring vane 4 is preferably arranged along shaft 3 spirals, the side wall upper part of described batch mixing tank body 1 is also equipped with bulky grain supply pipe 5, the bottom of batch mixing tank body 1 is back taper setting and base plate 8 is housed, on base plate 8, be rotatably connected to the discharging axle 10 being driven by discharging motor 9, a plurality of discharge blades 11 are housed on discharging axle 10, a plurality of discharge blades 11 are arranged and the length of discharge blade 11 diminishes from top to bottom gradually along discharging axle 10 spirals, can carry out again even to the material that is about to flow out, prevent segregation phenomenon, on base plate 8, be also provided with a plurality of discharge openings 12 that ring discharging axle distributes, the bottom of base plate 8 is equipped with and is accepted the delivery pipe 7 that discharge opening flows out material.

Described feed pipe 2 arranges many and be periphery along batch mixing tank body 1 altogether, feed pipe 2 is positioned at the inwall setting that the pipeline section of batch mixing tank body is pressed close to batch mixing tank body, the pipe clamp 13 of clamping feed pipe 2 is also housed on the inwall of batch mixing tank body 1, when motor 14 drives shaft 3 to rotate, can effectively prevent that feed pipe 2 is moved under the drive of material, thereby guarantee the stability of feed.

The utility model not only goes for ore dressing industry, also can stir for the batching of various industrial chemicals.
