Description

Technical Field

[0001] This utility model relates to the field of licorice stem and leaf feed processing technology, specifically a licorice stem and leaf feed pulverizing and mixing device. Background Technology

[0002] In the livestock feed processing sector, the rational utilization of licorice stems and leaves, as a feed resource with potential nutritional value, has attracted much attention. In traditional licorice stem and leaf feed processing, the crushing and mixing stages are often independent, requiring separate equipment. This not only increases equipment investment costs and floor space but also easily leads to material loss and contamination during transfer between different devices. Existing integrated crushing and mixing equipment suffers from poor crushing effect and uneven mixing, making it difficult to fully utilize the nutritional value of licorice stems and leaves. For example, the crushing components of some equipment have simple structures, failing to effectively break licorice stems and leaves into suitable particle sizes; the mixing components use a single stirring method, resulting in localized concentration differences in the feed during mixing, affecting feed quality. Furthermore, existing mixing devices do not provide sufficient contact between the material and the stirring components during mixing, easily creating mixing dead zones, further reducing mixing efficiency and quality. Therefore, developing a crushing and mixing device that can efficiently crush and uniformly mix licorice stem and leaf feed, with a compact structure and high practicality, is of significant practical importance.

A universal ball 167 is installed inside the universal seat 164. A spring 163 is fitted on the outside of the telescopic rod 162 between the fixed plate 161 and the universal seat 164.

[0043] The fixed plate 161 is made of stainless steel and is bolted to the mixing shaft 17. The telescopic rod 162 consists of an inner rod and an outer cylinder. The inner rod can freely extend and retract within the outer cylinder. It is made of high-strength alloy steel, possessing good strength and toughness. The spring 163 is a compression spring made of stainless steel wire, possessing high elasticity and corrosion resistance. It enables the telescopic rod 162 to automatically extend and retract when subjected to material resistance, ensuring full contact between the mixing blades and the material. The universal seat 164 and the universal ball 167 are both made of wear-resistant alloy material. The two work together to allow the mixing blades to flexibly change angle during rotation, improving the mixing effect.

[0047] The rotating cavity 165 provides installation space for the ball bearing 166, ensuring that the ball bearing 166 can roll freely. The ball bearing 166 is made of high-hardness alloy steel with a polished surface, resulting in low friction with the universal ball 167. This allows the universal ball 167 to rotate flexibly, thereby causing the mixing blades to change angle and achieve a more uniform mixing effect.

[0048] There are a total of 8 rotating cavities 165, which are evenly distributed on the inner wall of the universal joint 164; the diameter of the ball bearing 166 is 10mm;

[0049] A retaining ring is installed inside the rotating cavity 165 to prevent the ball 166 from falling off; a wear-resistant coating is applied to the surfaces of the universal seat 164 and the universal ball 167 to further improve their wear resistance.

[0050] In some technical solutions, a discharge pipe 12 is installed at the bottom of the mixer body 1, and the discharge pipe 12 is connected to the discharge port 14 of the mixing tank 11.

[0051] The discharge pipe 12 is made of seamless stainless steel, which has good sealing performance and corrosion resistance. Its diameter matches the discharge port 14 to ensure that the material can be discharged smoothly. The length of the discharge pipe 12 is set according to actual production needs, generally 1000-1500mm.

[0052] The diameter of the discharge pipe 12 is 200mm;

[0053] A valve and flow meter are installed on the discharge pipe 12 to control the discharge speed and measure the discharge volume; an insulation layer is installed on the outside of the discharge pipe 12 to prevent the feed temperature from dropping during the conveying process.

[0054] In some technical solutions, the top of the mixer body 1 is equipped with a licorice stem and leaf feed hopper 2.

[0055] The licorice stem and leaf feed hopper 2 is made of stainless steel and has a funnel-shaped structure. Its large opening diameter is 600mm, its small opening diameter is 300mm, and its height is 500mm, allowing for easy feeding of licorice stems and leaves into the grinding chamber 6. The feed hopper 2 is connected to the mixer body 1 via a flange, ensuring a tight and stable connection.

[0056] The inner wall of the feed hopper 2 is smooth and inclined at an angle of 60°, which facilitates the smooth sliding of materials.

[0057] A feed gate is installed above the feed hopper 2 to control the feeding speed and feed amount; an anti-stick coating is installed on the inner wall of the feed hopper 2 to prevent materials from adhering to the hopper wall.

[0058] In some technical solutions, the bottom of the mixer body 1 is equipped with a support base 3.

[0059] The support base 3 is welded from structural steel, making it robust and capable of withstanding the weight of the entire equipment and the vibrations generated during operation.

The dimensions of the support base 3 are designed based on the size of the mixer body 1, typically 1500mm in length, 1200mm in width, and 200mm in height.

[0060] The steel profile of the support base 3 is 100mm×100mm×5mm;

[0061] A horizontal adjustment bolt is installed on the support base 3 to adjust the level of the equipment and ensure the stability of the equipment operation; a guardrail is installed around the support base 3 to prevent operators from accidentally colliding with it.

[0062] Working Process and Principle: Feeding Stage: Licorice stems and leaves enter the equipment through the licorice stem and leaf feed hopper 2 at the top of the main body 1 of the mixer. The feed hopper 2 is funnel-shaped, with a diameter of 600mm at the wide end, 300mm at the narrow end, and a height of 500mm. The inner wall is inclined at a 60° angle and is smooth, facilitating the smooth sliding of materials. The feed gate above the feed hopper 2 controls the feeding speed and amount, preventing blockage caused by excessive or too rapid feeding. After entering, the material flows along the feed hopper 2 into the crushing chamber 6.

[0063] Crushing Stage: Inside the crushing chamber 6, two crushing shafts 7, driven by crushing motors 4, begin operation. Each crushing motor 4 has a power of 15kW and a rated speed of 1440r / min, and the two motors rotate in opposite directions. The crushing shaft 7 has a diameter of 50mm and a length of 800mm. Externally mounted crushing wheels 8 have a diameter of 300mm and a thickness of 50mm. Each crushing wheel 8 has eight evenly distributed crushing teeth, each 80mm long and 20mm apart. The relative rotation of the two crushing wheels 8 generates shearing force, crushing the licorice stems and leaves. The inclined guide plate at the bottom of the crushing chamber 6 smoothly guides the crushed material to the feed inlet 18 of the mixing tank 11.

[0064] Guiding and Conveying Stage: After the crushed material exits the crushing chamber 6, the short guide plate 9 on the left inner wall and the long guide plate 10 on the right inner wall of the mixer body 1 come into play. The short guide plate 9 is 400mm long and 150mm high, forming a 30° angle with the left inner wall; the long guide plate 10 is 800mm long and 150mm high, forming a 15° angle with the right inner wall. Working together, the two guide plates, through their smooth surfaces and specific angles, accurately guide the material to the feed inlet 18 at the top of the mixing tank 11. The flow regulating plate at the feed inlet 18 can flexibly control the speed of the material entering the mixing tank 11 according to actual production needs.

[0065] Mixing Stage: After the material enters the mixing tank 11, the mixing motor 5 drives the mixing shaft 17 to rotate. The mixing motor 5 has a power of 11kW and its speed can be adjusted within the range of 0-100r / min. The mixing shaft 17 has a diameter of 40mm and a length of 700mm, and six sets of mixing components 16 are evenly and equidistantly installed on its exterior, rotating accordingly. The telescopic rod 162 in the mixing component 16 can automatically extend and retract according to the material resistance under the action of the spring 163, ensuring full contact with the material. The universal seat 164 and the universal ball 167 cooperate to allow the mixing blades to flexibly change angle. The ball bearings 166 in the eight rotating cavities on the inner wall of the universal seat 164 reduce the rotational friction of the universal ball 167. At the same time, the protrusions 15 evenly distributed on the inner wall of the mixing tank 11 are 50mm high and have an arc of 120°, with eight protrusions per revolution, interacting with the mixing components 16 to enhance the stirring and agitation of the material, achieving uniform mixing.

[0066] Screening and Discharging Stage: The uniformly mixed material reaches the bottom of the mixing tank 11 and is discharged through the discharge port 14. The discharge port 14 has a diameter of 200mm, and the internal screen plate 13 has 2mm×2mm mesh openings, which can screen out materials that meet the particle size requirements. A vibration device below the screen plate 13 prevents material from clogging the screen openings, and a pneumatic valve at the discharge port 14 can precisely control the discharge speed and quantity. Qualified material enters the discharge pipe 12 through the discharge port 14. The discharge pipe 12 has a diameter of 200mm, and its outlet can be connected to conveying equipment to transport the feed to the next process. Valves and flow meters on the discharge pipe 12 can further control the discharge, and the external insulation layer can prevent the feed temperature from dropping.
