Description

Technical Field

[0001] This utility model relates to the technical field of feed-grade zinc oxide production equipment, specifically to a feed-grade zinc oxide grinding device. Background Technology

[0002] Zinc oxide is widely used in feed production, typically as a traditional additive to combat diarrhea and improve growth performance. To enhance zinc absorption by living organisms, ordinary feed-grade zinc oxide needs to be ground and then mixed with eutectic formations to form eutectic zinc oxide. The eutectic zinc oxide structure is more easily absorbed by animals, thereby effectively improving their health and production performance.

[0003] CN 211706940 U discloses a grinding and screening device for zinc oxide production. The main body of the grinding device has a sealing cover fixed to its top, a feeding port on one side of the sealing cover, and a grinding motor installed in the middle of the sealing cover. A grinding disc is fixed below the grinding motor, and a grinding plate is located below the grinding disc, with a sieving port on the grinding plate. The bottom end of a rotating column is connected to a blocking motor, and an opening is provided on the blocking plate. An air inlet is located at the bottom of one side of the main body of the grinding device, and a discharge port is located at the bottom of the other side of the main body. This device can sieve the ground zinc oxide powder after grinding the raw material and prevent clogging of the sieving holes at the grinding disc. However, the ground zinc oxide powder needs to be blown out of the main body using gas, and the heat generated during grinding is dissipated. When used to form a eutectic zinc oxide structure, it needs to be reheated. Utility Model Content

[0004] The purpose of this invention is to provide a feed-grade zinc oxide grinding device with a reasonable structure and reliable operation, which solves the problem of waste heat in the ground zinc oxide powder and makes full use of the grinding waste heat to form zinc oxide with a eutectic structure.

[0005] The technical solution of this utility model is:

[0006] A feed-grade zinc oxide grinding device includes a grinding box, a grinding chamber located at the top of the grinding box, and a grinding mechanism located in the grinding chamber. The key technical features are: the bottom of the grinding chamber is a sieve plate; a horizontal screw conveyor located below the sieve plate is built into the lower part of the grinding box; the tail section of the horizontal screw conveyor leads out of the grinding box and has a discharge port; a eutectic formation hopper is fixed above the tail section of the horizontal screw conveyor; the upper surface of the shell of the horizontal screw conveyor inside the grinding box is an open structure; inclined guide plates extending from the sieve plate to the open structure are symmetrically arranged in the grinding box; and a vibrating motor is fixed to the bottom surface of the horizontal screw conveyor.

[0007] The aforementioned feed-grade zinc oxide grinding device has a mixing chamber outside the grinding box, and the top surface of the mixing chamber has a feed inlet that connects to the discharge port of the horizontal screw conveyor.

[0008] The above-mentioned feed-grade zinc oxide grinding device has a servo motor fixed at the center of the top surface of the grinding box. The grinding mechanism includes a vertical shaft connected to the output end of the servo motor, positioning seats on both sides of the vertical shaft, a grinding roller frame symmetrically hinged to both sides of the positioning seats, and a grinding roller hinged to the grinding roller frame. The grinding roller is in contact with the upper surface of the sieve plate.

[0009] In the aforementioned feed-grade zinc oxide grinding device, a flow control valve is provided at the lower end of the eutectic formation hopper.

[0010] In the above-mentioned feed-grade zinc oxide grinding device, the sieve plate is conical, and a truncated cone is provided at the lower center of the sieve plate to prevent material accumulation. The top surface of the grinding box is provided with a feed pipe corresponding to the higher position of the sieve plate.

[0011] The beneficial effects of this utility model are:

[0012] Feed-grade zinc oxide, ground into fine powder in the grinding chamber, retains its own heat and is conveyed to its tail end via a horizontal screw conveyor. Simultaneously, the eutectic formant hopper discharges material into the tail end of the horizontal screw conveyor through a flow control valve. After mixing, both enter the mixing chamber. The inherent heat of the feed-grade zinc oxide accelerates the mixing reaction with the eutectic formant, forming zinc oxide with a eutectic structure. This invention solves the problem of wasted residual heat from grinding zinc oxide powder, fully utilizing the residual heat to form zinc oxide with a eutectic structure. Attached Figure Description

[0017] like Figure 1 , Figure 2 As shown, the feed-grade zinc oxide grinding device includes a grinding box 1, a grinding chamber located on the upper part of the grinding box 1, and a grinding mechanism located in the grinding chamber.

[0018] The grinding chamber has a sieve plate 14 at its bottom and a servo motor 3 fixed at the center of its top surface. The grinding mechanism includes a vertical shaft 4 connected to the output end of the servo motor 3, positioning seats 5 on both sides of the vertical shaft 4, a grinding roller frame 6 symmetrically hinged to both sides of the positioning seats 5, and a grinding roller 7 hinged to the grinding roller frame 6. The grinding roller 7 is in contact with the upper surface of the sieve plate 14. The sieve plate 14 is conical, with a truncated cone at its lower center to prevent material accumulation. The top surface of the grinding chamber 1 has a feed pipe 2 corresponding to the higher position of the sieve plate 14.

[0019] The grinding chamber 1 has a horizontal screw conveyor 9 located below the sieve plate 14. The tail section of the horizontal screw conveyor 9 extends out of the grinding chamber 1 and has a discharge port. A eutectic formation hopper 8 is fixed above the tail section of the horizontal screw conveyor 9. A flow control valve is provided at the lower end of the eutectic formation hopper 8. A stirring chamber 10 is provided outside the grinding chamber 1, and the top surface of the stirring chamber 10 has a feed port that connects to the discharge port of the horizontal screw conveyor 9.

[0020] The horizontal screw conveyor 9 has an open structure 12 on the upper surface of the shell inside the grinding box 1. The grinding box 1 is symmetrically provided with inclined guide plates 13 extending from the sieve plate 14 to the open structure 12. A vibration motor 11 is fixed on the bottom surface of the horizontal screw conveyor 9.

[0021] Working principle:

[0022] 1. Feed-grade zinc oxide is fed into the grinding chamber through the feed pipe 2. The servo motor 3 is started. The servo motor 3 drives the vertical shaft 4, positioning seat 5, grinding roller frame 6 and grinding roller 7 to rotate, and grind the material falling on the screen plate 14.

[0023] 2. With the assistance of the vibrating motor 11, the fine powder on the sieve plate 14 falls through the sieve holes and falls along the inclined guide plate 13 to the open structure 12 of the horizontal screw conveyor 9. It enters the horizontal screw conveyor 9 through the open structure 12 and is then conveyed to the tail section of the horizontal screw conveyor 9 by the screw blades.

[0024] 3. The eutectic formant discharge hopper 8 discharges material to the tail section of the horizontal screw conveyor 9 through the flow control valve. After mixing with the finely ground feed-grade zinc oxide, the mixture enters the mixing chamber 10. The ground feed-grade zinc oxide has its own heat, which accelerates the mixing reaction with the eutectic formant to form zinc oxide with a eutectic structure.
