DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0015] Embodiment, please refer to Figs. 1-2The utility model provides a technical scheme: a kind of feed additive mixing device, including air blower 1 and cyclone 2;The air outlet pipe 11 of air blower 1 is communicated at the bottom of expansion pipe 3;Vertical elbow pipe 4 is connected to the top end of expansion pipe 3, and the end of vertical elbow pipe 4 is connected with the feed inlet of cyclone 2;The upper end of granular bin 5 is butt-jointed to the discharge port of the lower end of cyclone 2;The lower end of granular bin 5 is equipped with discharge pipe 51, and the end of discharge pipe 51 is equipped with hand valve 52;In the middle part of discharge pipe 51, inclined pipe 53 is communicated, and the end of inclined pipe 53 is communicated on the side wall of air outlet pipe 11;First electric control flow valve 54 is equipped on inclined pipe 53;Further including oil storage bottle 6, pressurizing device 61 and oil injection pipe 62 are equipped on the oil storage bottle 6, oil injection pipe 62 is inserted into the inside from the lower end side wall of vertical elbow pipe 4, and the end thereof is equipped with the spray head 63 extending to the inside of expansion pipe 3;Second electric control flow valve 65 is equipped on oil injection pipe 62.

[0016] When using, first open air blower 1.And then control first electric control flow valve 54 to open, and granular material enters expansion pipe 3, because the pipe diameter of expansion pipe 3 suddenly expands, airflow slows down, and granules are dispersed and float;At this time, second electric control flow valve 65 is opened, and oiliness feed additive is sprayed, and oil mist collides and mixes with floating granules, and part of granules is discharged from vertical elbow pipe 4 after mixing, and another part of granules is settled at the bottom of expansion pipe 3 and is blown up again when passing through the pipe opening of air outlet pipe 11, to continue to participate in mixing until being blown into vertical elbow pipe 4.Granules enter vertical elbow pipe 4 and are introduced into cyclone 2 to carry out solid-gas separation, and granules with large specific gravity fall down, and air with light specific gravity is discharged from the upper air outlet.Granules after initial mixing fall into granular bin 5, and the material in granular bin 5 enters air outlet pipe 11 again to circulate and reciprocate to carry out material mixing.Pressurizing device 61 provides pressure for oil injection, and spray head 63 sprays additive into mist, which is beneficial to mixing.After multiple cycles, second electric control flow valve 65 is closed to stop supplying oiliness additive, and then first electric control flow valve 54 is closed to stop outputting granules to expansion pipe 3.Air blower 1 keeps working until all granules flow back to granular bin 5, and then air blower 1 is closed.Finally, hand valve 52 at the end of discharge pipe 51 is opened to discharge mixed granules, and mixing operation is completed.It can be seen that air blower 1, air outlet pipe 11, expansion pipe 3, vertical elbow pipe 4 and cyclone 2 form a pipeline for pneumatic conveying of granules to provide power for movement of granules.First flow electric valve controls the supply amount of granular material, and second electric control flow valve 65 controls the supply amount of additive, so that additive can be fully dispersed in granules, mixing is uniform, and the quality of mixing is improved.Under the action of air blower 1, continuous mixing is carried out by circulation and reciprocation, continuous work is carried out, and the efficiency of mixing is improved.

[0017] In order to make structure compact, the oil storage bottle 6 is fixedly connected with the vertical elbow pipe 4 through support frame 64.

[0018] In order to further improve the uniformity and efficiency of the mixing, the expansion pipe 3 is divided into three sections from bottom to top, namely, the expansion section 31, the parallel section 32 and the contraction section 33; the sieve disc 34 is arranged in the contraction section 33, the center of the sieve disc 34 is provided with a circular hole 35 for the oil injection pipe to pass through, and a plurality of support rods 37 are fixed to the side wall of the sieve disc 34; the ends of the support rods 37 are fixed to the inner wall of the expansion pipe 3, and the sieve disc 34 is suspended in the middle of the contraction section 33; the sieve disc 34 is provided with a plurality of through holes 36. The oil injection pipe 63 is arranged in the contraction section 33, and it is the only way for the particles to enter the vertical elbow pipe 4, thereby reducing the particles that are not combined with the oil mist entering the vertical elbow pipe 4. The sieve disc 34 can block the particles in the middle airflow, reduce the flow rate of the particles, and prevent the particles in the middle from being discharged without being fully mixed due to the too fast airflow from the air outlet pipe 11. The sieve disc 34 is provided with a plurality of through holes 36, which can ensure that a part of the airflow and particles pass through, and the particles that do not pass through the sieve disc 34 are bounced back and fall again, and then are impacted by the airflow to hit the sieve disc 34, thereby making the particles form a dense concentration area below the sieve disc 34, improving the probability of combination with the oil mist, and making the mixing more efficient. The sieve disc 34 also prevents the oil mist from directly entering the vertical elbow pipe 4, thereby avoiding waste. The airflow is made to be tortuous, so that more airflow enters the vertical elbow pipe 4 from the periphery of the sieve disc 34, thereby reducing the flow rate and providing conditions for the oil mist to collide and mix again in the vertical elbow pipe 4.

[0019] In order to further improve the efficiency of the mixing, the particle bin 5 is provided with a stirring device for stirring the particle materials in the bin. The particles after the last mixing collide and mix with the particles in the bin again, thereby improving the efficiency of the mixing.

[0020] In order to improve the stirring effect, the stirring device comprises a stirring shaft 55 arranged in the center of the particle bin 5, the upper end of the stirring shaft 55 is connected with a motor 56 fixed to the top end of the particle bin 5, and a spiral blade 57 is fixed to the stirring shaft 55.

[0021] More preferably, a plurality of stirring rods 58 are fixed to the stirring shaft 55 and are distributed in a spiral shape around the stirring shaft 55; the stirring rods 58 are arranged horizontally, and a stirring spoon 59 is fixed to the end of each stirring rod 58. The stirring is more sufficient, and the efficiency of the mixing is higher.

[0022] The advantages of the embodiment are that the device can mix the oily feed additive with the floating feed particles while the particle materials are being pneumatically conveyed, and the oily additive is gradually dispersed through the circulation of the particle materials, thereby improving the uniformity of the dispersion of the additive and improving the production efficiency of the mixing.

[0023] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
