Technical Field

The invention relates to a frequency-conversion material shifting and discharging device for a material bin.

Background

The storage bin is a common device for storing and discharging materials in the industrial production process, the materials are compacted and agglomerated in long-term storage, and solid low-fluidity and high-pressure barrier property can be formed after gas in powder naturally escapes upwards under pressure in the case of long-term static deposition, so that the phenomenon of incontrollable blockage and material breakage is easily caused; when the water content in the storage bin is too high or the materials are materials which are not easy to flow, the phenomena of arching or compaction, unsmooth discharging and the like are easy to occur near the discharge hole of the hopper, so that the flowing of the materials is seriously influenced, and the storage bin materials cannot be normally supplied; these phenomena bring great difficulty to the technical treatment of unloading for the quantification of the powder bin bottom, and directly affect the guarantee and promotion of the subsequent process production quality, thereby affecting the normal operation of production.

Detailed Description

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings.

Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

With the help of attached drawings, the bin frequency conversion material stirring and discharging device comprises a bin shell body 3 and a frequency conversion variable pitch screw machine 4, wherein the frequency conversion variable pitch screw machine 4 penetrates through the bin shell body 3, a supporting leg 6 is arranged in the bin shell body 3, a material stirring device mounting frame 7 is arranged on the supporting leg 6, a frequency conversion material stirring device 2 is arranged in the center of the material stirring device mounting frame 7, the frequency conversion variable pitch screw machine 4 is arranged above the frequency conversion material stirring device 2, and a bin pressure reducing device 1 is arranged at the top of the frequency conversion material stirring device 2;

the variable-frequency material stirring device 2 comprises a variable-frequency motor 8, a gear 9 is arranged on the variable-frequency motor 8, and a flexible material stirring arm 5 is arranged on the gear 9.

When the variable-frequency variable-pitch screw machine is implemented specifically, the variable-frequency motor drives the large gear to drive the flexible stirring arm to rotate, stirring is carried out at the bottom of the storage bin, the flexible stirring arm carries materials into a shell of the variable-frequency variable-pitch screw machine, and the materials are carried out along with the variable-frequency variable-pitch screw machine. Because the material produces higher holding down force in the storage process in the feed bin, the material is stirred to the flexible arm of dialling and to adopt slow speed, big moment mode, need adopt the frequency conversion, and this problem is solved to large-scale gear. Because the pressure of the center part of the storage bin is larger, the pitch of the middle part of the discharging screw machine is the smallest, the pitch of the discharging end is the largest, and the pitches are uniformly changed.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
