Referring to fig. 1, in a first aspect, the present embodiment provides a particulate material mixing device 1, including a mixing bin 11, a main discharging pipe 12 and a discharging pipe 13, where the mixing bin 11 is filled with particulate material; the main discharging pipe 12 is arranged at the lower part of the mixing bin 11, and the main discharging pipe 12 is used for enabling the granular materials in the middle part of the mixing bin 11 to flow out; the blanking pipe 13 is arranged in the circumferential direction of the mixing bin 11, an outlet of the blanking pipe 13 is communicated with an outlet of the main blanking pipe 12, the radial size of the blanking pipe 13 is smaller than that of the main blanking pipe 12, and the blanking pipe 13 is used for enabling particles at the edge of the mixing bin 11 to be gathered into the main blanking pipe 12 and flow out.

In this embodiment, the mixing bin 11 is a vertically placed tank, a feed inlet is arranged at the top of the tank, and different types of granular materials enter the mixing bin 11 through the feed inlet to be mixed. The main discharging pipe 12 is provided at a lower portion of the mixing bin 11, and as a preferred embodiment, the main discharging pipe 12 is provided at a central axis of the mixing bin 11. When the granule is output from the mixing bin 11, the mixing bin 11 will form a vortex at the main discharge pipe 12, optionally the main discharge pipe 12 is arranged at the central axis of the mixing bin 11 such that the main discharge pipe 12 is equidistant from the inner side walls of the mixing bin 11 for uniform blending.

The number of the blanking pipes 13 is plural, and the blanking pipes are circumferentially arranged on the mixing bin 11, specifically at the edge of the mixing bin 11. As a preferred embodiment, the number of the blanking pipes 13 may be 6, 8 or 10.

By additionally arranging a plurality of blanking pipes 13 at the edge of the mixing bin 11, the particles attached to the edge of the mixing bin 11 can be converged to the outlet of the main blanking pipe 12 through the blanking pipes 13, the radial size of the blanking pipes 13 is smaller than that of the main blanking pipe 12, and on the premise of not influencing the blanking rate of the particles in the main blanking pipe 12, the particles at the edge of the mixing bin 11 and the particles flowing through the middle part of the mixing bin 11 of the main blanking pipe 12 flow out from the outlet of the main blanking pipe 12 simultaneously after being mixed, so that the problem of uneven mixing of the mixed particles in the mixing bin 11 is solved, and meanwhile, the output efficiency of the mixed particles in the mixing bin 11 is ensured.

Referring to fig. 1, in some embodiments, a guiding structure 14 is further disposed between the main discharging pipe 12 and the mixing bin 11, and the guiding structure 14 is used for guiding the particulate material in the mixing bin 11 to the inlet of the main discharging pipe 12. The guiding structure 14, the mixing bin 11 and the main discharging pipe 12 can be made in an integrated mode or can be arranged in a split mode. In this embodiment, the radial dimension of the main discharging pipe 12 is smaller than the radial dimension of the mixing bin 11, and the guiding structure 14 forms an included angle with the central axis of the mixing bin 11 in the vertical direction. By arranging the guide structure 14, the transition effect is achieved in the process that the particles enter the main blanking pipe 12 from the mixing bin 11, and the influence on the blanking rate of the main blanking pipe 12 due to the fact that the particles are clamped with each other or clamped on the inner wall of the mixing bin 11 in the process is avoided.

Referring to fig. 1, in some embodiments, the guiding structure 14 is an inclined plane 141, and two ends of the inclined plane 141 are respectively connected with the mixing bin 11 and the main discharging pipe 12; alternatively, the guide structure 14 is a plurality of drainage partitions arranged along the circumferential direction of the mixing bin 11.

When the guiding structure 14 is the inclined plane 141, since one end of the guiding structure 14 is connected with the mixing bin 11 and the other end of the guiding structure 14 is connected with the main discharging tube 12, the shape of the guiding structure 14 is limited by the shapes of the main discharging tube 12 and the mixing bin 11, and taking the main discharging tube 12 and the mixing bin 11 as the cylinders, one end of the guiding structure 14 is connected with the bottom edge of the mixing bin 11 and the other end of the guiding structure 14 is connected with the inlet of the main discharging tube 12, and the guiding structure 14 is in a shape of a truncated cone at this time.

Because the friction force between the particles is large, the particles are not easy to roll, the middle part of the particles in the main blanking pipe 12 is less to participate in mixing in the transportation process, and still insufficient mixing exists, so that the blowing device 15 is arranged below the junction of the main blanking pipe 12 and the blanking pipe 13, and compared with the mixing in the mixing bin 11, the diameter of the main blanking pipe 12 is small, and the blowing device 15 can completely mix the particles at the position of the blanking pipe 13 with the particles at the position of the main blanking pipe 12.

The granule flowing out of the blanking pipe 13 is blown to the inside of the main blanking pipe 12 by the blowing mode, so that the granule of the main blanking pipe 12 is further mixed with the granule of the blanking pipe 13.

Referring to fig. 2, in some embodiments, the number of blowing devices 15 is plural, and the blowing devices are disposed along the circumferential direction of the main blanking pipe. By providing a plurality of blowing devices 15, the particles of the blanking pipe 13 and the particles of the main blanking pipe 12 can be mixed from different directions, which is more helpful for uniformly mixing the particles of the blanking pipe 13 and the particles of the main blanking pipe 12.

As a preferred embodiment, the plurality of blowing devices 15 and the blanking pipes 13 are staggered in the circumferential direction of the main blanking pipe 12, so that the particles in the plurality of blanking pipes 13 and the particles in the main blanking pipe 12 can be uniformly mixed in time, and the mixing efficiency is improved.

Referring to fig. 3 to 5, in a second aspect, the present embodiment further provides a particulate material mixing system, including a feed hopper 3, a mixing device set 2, and a particulate material conveying pipeline 4, where the feed hopper 3 is filled with particulate materials to be mixed; the mixing device group 2 comprises a mixing device 1, wherein the mixing device 1 is the mixing device 1 in the first aspect, a feed hopper 3 is connected with a feed inlet of the mixing device 1, and a discharge outlet of the mixing device 1 is communicated with a granule conveying pipeline 4.

Optionally, a plurality of mixing devices 1 are connected in series relative to the granule conveying pipeline 4, namely, the discharge port of one mixing device 1 is communicated with the feed port of the next mixing device 1, and the discharge port of the last mixing device 1 is communicated with the granule conveying pipeline 4; or, a plurality of mixing devices 1 are connected in parallel relative to the granule conveying pipeline 4, that is, the discharge port of each mixing device 1 is respectively communicated with the granule conveying pipeline 4, and the granule conveying pipeline 4 can convey the mixed granule to the next process.

Referring to fig. 3, in some embodiments, the mixing device set 2 includes a first mixing device 21 and a second mixing device 22, the first mixing device 21 includes a first discharge port 211 and a second discharge port 212, the first discharge port 211 is connected with a feed port of the second mixing device 22, the second discharge port 212 is communicated with the particulate material conveying pipeline 4, and a discharge port of the second mixing device 22 is connected with a feed port of the first mixing device 21.

In this embodiment, in order to distinguish a plurality of mixing devices 1 in the same mixing device group 2, one mixing device 1 is denoted as a first mixing device 21, the other mixing device 1 is denoted as a second mixing device 22, and the first mixing device 21 and the second mixing device 22 have the same structure; and the third mixing device 1, the fourth mixing device 1 and the like can be added on the basis, different particles to be mixed can be added in different mixing devices, or different mixing modes can be set in different mixing devices, so that the mixing requirements of different stages of the particles can be realized.

For example, when the first outlet 211 is closed and the second outlet 212 is opened, the blended particles may flow directly into the particle delivery conduit 4 through the first mixing device 21 to further proceed to the next operation. When the second discharging hole 212 is closed and the first discharging hole 211 is opened, the blended particulate material needs to gradually pass through the first mixing device 21, the second mixing device 22 and the first mixing device 21 before being output into the particulate material conveying pipeline 4.

When the particle material B is required to be added into the second mixing device 22, and the particle material B is mixed with the mixed particle material A, the particle material B is filled in the feed hopper 3, and the opening and closing valve 5 between the feed hopper 3 and the feed inlet of the second mixing device 22 is only opened, so that the particle material B enters the second mixing device 22; simultaneously, the opening and closing valve 5 at the first discharging hole 211 of the first mixing device 21 is opened, so that the uniformly mixed granular material A in the first mixing device 21 enters the second mixing device 22, and the granular material B and the granular material A are mixed in the second mixing device 22.

When the same type of granular materials are mixed, the quantity distribution of the same type of granular materials in different mixing devices 1 can be realized by switching the on-off valve 5 between the different mixing devices 1 and the feeding hopper 3.

As an alternative embodiment, the mixing system further comprises a control unit electrically connected to the on-off valves 5 of the various delivery nodes, which refer to the connecting lines between the different devices, for example: the connecting pipeline between the feed hopper 3 and the feed inlet of the first mixing device 21 is a conveying node. When a plurality of mixing device groups 2 are arranged, the control unit is also electrically connected with an opening and closing valve 5 at a conveying node in the plurality of mixing device groups 2.
