Description

Technical Field

[0001] The present invention belongs to the field of feed additive production equipment, and relates to a concentrated feed equipment, specifically a concentrated feed equipment with a vibration screening device. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing, and use of feed. They have a significant effect although used in small amounts in feed. Feed additives are essential raw materials in modern feed industry, which have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving the quality of livestock products. In the production of feed additives, a concentration equipment is generally used to evaporate the water in the additive raw materials by heating evaporation to concentrate the raw materials.

[0003] The Chinese patent for a concentrated equipment for feed additives with the application number 202321869897.2 discloses a concentrated equipment for feed additives, including a processing cylinder. The top of the processing cylinder is movably connected with a cover plate. The top of the cover plate is fixedly connected with a first motor. The output shaft of the first motor is fixedly connected with a mounting plate through a coupling. The bottom of the mounting plate is movably connected with a connecting plate. The bottom of the connecting plate is fixedly connected with a rotating shaft. A connecting frame is fixedly connected to the outer wall of the rotating shaft. A scraping plate is fixedly connected to one side of the connecting frame. A fixing block is fixedly connected to the outer wall of the rotating shaft. This concentrated equipment for feed additives can push and discharge materials after concentrating the feed additives, and can scrape the raw materials attached to the inner wall of the processing cylinder while discharging. Although it effectively improves the discharging speed of the raw materials, and at the same time avoids blockage during discharging, and can reduce the waste caused by raw material residue, it further improves the practicability of the concentrated equipment.

[0004] However, during feeding, uneven particle size of the feed will have significant impacts in many aspects during the concentration process. On the one hand, it will lead to uneven flow and heat transfer of the material in the concentration equipment. Large particles precipitate, affecting circulation and reducing heat transfer effect. Small particles are easily carried out by the flow, which not only prolongs the concentration time and reduces efficiency, but also causes material loss. On the other hand, it will make the quality of the concentrated product non-uniform. Different-sized particles have different heat and mass transfer, resulting in differences in the physical properties and purity of the product, affecting the consistency and stability of the product. Especially in pharmaceutical production, it will also affect the efficacy and safety of the drug. In addition, uneven particles will increase the risk of equipment wear and blockage. Large particles wear equipment components, and the combined action of large and small particles easily blocks the pipeline, reducing the service life of the equipment, increasing the maintenance cost, and even requiring production suspension for cleaning, causing losses to production.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and understanding the present invention, and are not used to limit the present invention.

One end of the power rod 12 away from the extension piece 11 is fixedly connected to a first vibration block 32 and fixed on the side of the first vibration block 32; a fixed ring 31 is also sleeved on the end of the first vibration block 32 where the power rod 12 is fixed. A connecting rod 30 is fixedly arranged on the fixed ring 31. One end of the connecting rod 30 away from the fixed ring 31 is fixed with a second vibration block 35. Main vibration springs 33 are arranged at the top and bottom of the first vibration block 32 and the second vibration block 35; bearing plates 29 are respectively fixedly arranged on the sides of the first vibration block 32 and the second vibration block 35 away from the connecting rod 30. Auxiliary vibration springs 18 are arranged on the upper and lower sides of one end of each bearing plate 29 away from the first vibration block 32 and the second vibration block 35.

[0032] On each receiving plate 29, a large-hole screen 13 and a fine screen 17 are fixedly arranged from top to bottom respectively.

[0033] At the connection between the screening assembly and the concentration kettle 3, a one-way blocking assembly with a downward opening is arranged. The one-way blocking assembly includes a second rotating rod 16 fixed at the connection between the screening assembly and the concentration kettle 3. Two rotating sleeves are sleeved on the second rotating rod 16. On one side of each rotating sleeve facing the screening assembly, a limiting plate 14 is fixedly arranged; on both horizontal sides of the rotating sleeve, blocking plates 15 covering the opening of the concentration kettle 3 are rotatably arranged respectively.

[0034] At the top inside the concentration kettle 3, a spraying assembly 1 is arranged. The spraying assembly 1 includes a liquid spraying pipe 24 arranged around the top inside the concentration kettle. The liquid spraying pipe 24 is communicated with a liquid inlet pipe 25; one end of the liquid inlet pipe 25 is communicated with the liquid spraying pipe 24, and the other end of the liquid inlet pipe 25 far from the connection with the liquid spraying pipe 24 passes through the wall of the concentration kettle 3, and the connection with the wall of the concentration kettle 3 is sealed; a stirring rod 26 is movably arranged through the bottom of the concentration kettle 3. A stirring blade 27 is fixedly arranged on the part of the stirring rod 26 placed inside the concentration kettle 3. A stirring motor 34 is fixedly arranged at the end of the stirring rod 26 placed outside the concentration kettle 3. The power output end of the stirring motor 34 is fixedly connected with the end of the stirring rod 26 placed outside the concentration kettle 3.

[0035] A spiral heating pipe 28 is spirally arranged at the bottom of the concentration kettle 3.

[0036] An observation hole is opened on the side wall of the concentration kettle 3, and an observation window 2 is hermetically arranged outside the observation hole.

[0037] A cooling circulation assembly 7 is arranged on the side wall of the concentration kettle 3. The cooling circulation assembly 7 is communicated with the concentration kettle 3 through a gas guide pipe 9 and a return pipe respectively; a valve 5 is arranged on the return pipe.

[0038] The cooling circulation assembly 7 is also provided with a condensate inlet pipe 6 and a condensate outlet pipe 8.

[0039] A discharge pipe 23 is communicated with the bottom of the concentration kettle 3.

[0040] When using this embodiment, the material to be processed enters from the semi-open top cover at the top of the screening barrel 20. The vibration motor 10 is started, and the power output end of the motor drives the extension piece 11 to vibrate, and then the power rod 12, the first vibration block 32 and the second vibration block 35 vibrate at high frequency under the action of the main vibration spring 33. This vibration is transmitted to the receiving plate 29, so that the large-hole screen 13 and the fine screen 17 on the receiving plate 29 screen the material. Large-particle impurities are intercepted by the large-hole screen 13, and the material meeting the particle size requirements falls downward through the screen.

[0041] The screened material enters the concentration kettle 3 through the one-way blocking component at the connection between the screening component and the concentration kettle 3. Under the action of the second rotating rod 16 and the rotating sleeve, the limiting plate 14 and the blocking plate 15 of the one-way blocking component ensure that the material can only enter the concentration kettle 3 unidirectionally, preventing the material in the concentration kettle 3 from flowing back.

[0042] After the material enters the concentration kettle 3, the liquid spraying pipe 24 introduces relevant liquid through the liquid inlet pipe and sprays it evenly on the material. At the same time, the stirring motor 34 drives the stirring rod 26 and the stirring blades 27 to rotate, so that the material is fully mixed with the liquid. The spiral heating pipe 28 at the bottom of the concentration kettle 3 starts to work to heat the material and promote the concentration of the material.

[0043] The steam generated during the concentration process enters the cooling circulation component 7 through the air duct. The cooling circulation component 7 uses the condensate inlet pipe 6 and the condensate outlet pipe 8 for heat exchange, cools the steam into a liquid, and returns it to the concentration kettle 3 through the return pipe or for recycling. The valve 5 on the return pipe can control the return speed.

[0044] The operator can observe the concentration situation of the material in real time through the observation window on the side wall of the concentration kettle 3 and adjust parameters such as the stirring speed, heating temperature, and liquid spraying amount according to the actual situation.

[0045] The concentrated material is discharged through the discharge pipe 23 connected to the bottom of the concentration kettle 3 and enters the subsequent processing link.

[0046] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
