DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 and Figure 2 As shown, a feed additive drying device includes a shell 1, support legs 2 are fixedly connected to the four corners of the lower end of the shell 1, a control box 3 is fixedly installed on the front end of the shell 1, a hopper 4 is fixedly connected to the upper end of the shell 1, a pretreatment component 5 is arranged in the inner cavity of the hopper 4, and a drying component 6 is arranged in the inner cavity of the shell 1.

[0033] During the implementation of this embodiment, a viscous liquid feed additive is placed in a hopper 4, and by operating the control box 3, the pretreatment component 5 filters the viscous liquid feed additive to remove large particles of debris inside, and removes bubbles in the viscous liquid feed additive during mixing and vibration. After pretreatment, the viscous liquid feed additive is extracted and sprayed during the rotation of the drying component 6, and the drying operation is performed by steam.

[0034] The control box 3 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its controllable functions are utilized, and its internal structure, connection method and principle are not further explained.

[0035] Specifically, in order to achieve pretreatment of viscous liquid feed additives, refer to Figure 3 , Figure 5 and Figure 6 In this embodiment, the pretreatment component 5 includes a fixing frame 51 fixedly connected to the inner surface of the hopper 4, a mixing mechanism 52 is arranged at the lower end of the fixing frame 51, a filtering mechanism 53 is arranged on the inner surface of the hopper 4, and a vibration mechanism 54 is arranged on the inner surface of the hopper 4 above the filtering mechanism 53.

[0036] For further information, see Figure 3 and Figure 6 In this embodiment, the filtering mechanism 53 includes a filtering plate 531 fixedly connected to the inner surface of the hopper 4, and a scraper 532 tightly attached to the upper end of the filtering plate 531 is fixedly connected to the outer surface of the stirring rod 527.

[0037] For further information, see Figure 3 and Figure 5 In this embodiment, the mixing mechanism 52 includes a double-axis motor 521 fixedly connected to the left end of the outer shell 1, the left end output end of the double-axis motor 521 is fixedly connected to a rotating rod 522 through a coupling, the lower end of the fixed frame 51 is fixedly connected to a hollow block 523, the outer surface of the hopper 4 passes through and extends to the inner surface of the hollow block 523 and is rotatably connected to a transmission rod 524, the upper end of the fixed frame 51 passes through and extends to the lower end of the hollow block 523 and is rotatably connected to a stirring rod 527, the outer surfaces of the transmission rod 524 and the rotating rod 522 are jointly fixedly connected to a pulley group 525, the outer surfaces of the transmission rod 524 and the stirring rod 527 are jointly fixedly connected to a gear group 526, the inner surface of the rotating rod 522 is slidably connected to a buoyancy ball 528, and the outer surface of the buoyancy ball 528 is fixedly connected to a burr rod 529.

[0038] During the implementation process, the viscous liquid feed additive is put into the hopper 4, and firstly, it is filtered through the filter plate 531 under the action of gravity, so that the large particles of debris in the viscous liquid feed additive are retained on the filter plate 531, and then the left end output end of the dual-axis motor 521 is started to drive the rotating rod 1 522 to rotate through the coupling, and the stirring rod 527 is driven to rotate under the transmission action of the pulley group 525, the transmission rod 524 and the gear group 526, thereby driving the stirring plate on the stirring rod 527 to mix the viscous liquid feed additive. The bubbles in the viscous liquid feed additive continuously float on the surface of the viscous liquid feed additive during the stirring process, and at the same time, the buoyancy ball 528 floats on the surface of the viscous liquid feed additive. As the stirring rod 527 rotates, the bubbles floating on the surface of the liquid feed additive can be punctured by the burr rod 529, which helps to improve the uniformity of the viscous liquid feed additive, reduce the formation of bubbles and gaps, avoid uneven drying effects or the generation of pores during the drying process, thereby improving the drying efficiency and the quality of the finished product, and improving the density and stability.

[0039] The pulley assembly 525 is composed of two pulleys and a belt.

[0040] The gear set 526 mentioned above is composed of two bevel gears.

[0042] As can be seen from the above, the stirring rod 527 will drive the fixed block 542 to rotate during the rotation. Since the knocking rod 543 and the fixed block 542 are slidably connected, the knocking rod 543 can intermittently impact the circular groove on the circular groove ring 541 under the tensile deformation force of the spring 544, so that the hopper 4 vibrates, which helps to promote the uniform distribution of the viscous liquid feed additive and reduce the aggregation of bubbles and large particles in the liquid, thereby improving the heat exchange efficiency during the drying process and the drying uniformity of the viscous liquid feed additive. At the same time, vibration can help improve the fluidity of the viscous liquid feed additive, avoid agglomeration caused by high viscosity, and ensure that the dried product has better quality and stability.

[0043] Embodiment 2: Based on Embodiment 1, this embodiment adds a drying component 6 for drying the viscous liquid feed additive, so as to achieve the purpose of drying the viscous liquid feed additive.

[0044] Specifically, in order to dry viscous liquid feed additives, refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 In this embodiment, the drying component 6 includes a collecting frame 61 movably mounted on the shell 1, a hydraulic mechanism 62 is provided at the lower part of the inner surface of the shell 1, a spraying mechanism 63 is provided on the inner surface of the shell 1, and a drying mechanism 64 is provided on the inner surface of the shell 1.

[0045] For further information, see Figure 3 and Figure 7 In this embodiment, the hydraulic mechanism 62 includes a placement box 621 fixedly connected to the lower part of the inner surface of the shell 1, a cylinder 622 is fixedly connected to the right part of the inner surface of the shell 1, a piston rod 623 is slidably connected to the inner surface of the cylinder 622, a spring 624 is sleeved on the outer surface of the piston rod 623, and the two ends of the spring 624 are respectively fixedly connected to the inner surface of the cylinder 622 and the piston on the piston rod 623, a connecting pipe 626 is fixedly connected to the upper part of the inner surface of the placement box 621 and extends to the inner surface of the cylinder 622, an oil pump 627 is fixedly connected to the lower end of the connecting pipe 626, and an extrusion ring 625 is fixedly connected to the left end of the piston rod 623.

[0046] For further information, see Figure 3 , Figure 8 and Fig. 9 In this embodiment, the spraying mechanism 63 includes an annular plate 631 fixedly connected to the inner surface of the housing 1 and the outer surface of the second cylinder 629. The right end output end of the dual-axis motor 521 is fixedly connected to the second rotating rod 632 rotatably connected to the housing 1 through a coupling. The inner surface of the second rotating rod 632 is slidably connected to the third piston rod 633. The right end of the third piston rod 633 is fixedly connected to the extrusion wheel 634. The outer surface of the third piston rod 633 is sleeved with a fourth spring 635. The two ends of the fourth spring 635 are respectively connected to the inner surface of the second rotating rod 632. The outer surface of the rotating rod 2 632 is rotatably connected to the piston on the piston rod 3 633, and the inner cavities of the two ring groove blocks 636 are communicated with the inner surface of the rotating rod 2 632, and the inner surfaces of the two ring groove blocks 636 are fixedly installed with one-way valves 639, and the upper end of the right one-way valve 639 is fixedly connected to a connecting pipe 1 637 fixedly connected to the lower part of the inner surface of the hopper 4, and the upper end of the left one-way valve 639 is fixedly connected to a connecting pipe 2 638 fixedly connected to the annular plate 631.

[0047] For further information, see Figure 3 , Figure 8 and Fig. 9 In this embodiment, the inner surface of the connecting tube 1 626 is fixedly connected to the connecting tube 2 628, the outer surface of the connecting tube 2 628 is fixedly connected to the cylinder 2 629, the inner surface of the cylinder 2 629 is slidably connected to the piston rod 2 6210, one end of the piston rod 2 6210 is fixedly connected to the scraper 2 6212, the outer surface of the piston rod 2 6210 is sleeved with a spring 3 6211, the two ends of the spring 3 6211 are respectively fixedly connected to the inner surface of the cylinder 2 629 and the piston on the piston rod 2 6210, and a solenoid valve 6213 is fixedly installed at the intersection of the outer surfaces of the connecting tube 1 626 and the connecting tube 2 628.

[0048] During the implementation process, by starting the oil pump 627, the oil pump 627 draws the hydraulic oil in the placement box 621 into the cylinder 1 622 through the connecting pipe 1 626, and then under the action of the hydraulic pressure, the extrusion ring 625 on the piston rod 1 623 is pushed to the left, so that the spring 2 624 is in a compressed state. When the extrusion ring 625 moves to the set position, the right end output end of the dual-axis motor 521 is started to drive the rotating rod 2 632 to rotate through the coupling, thereby driving the extrusion wheel 634 on the piston rod 3 633 to reciprocate on the outer surface under the cooperation of the extrusion ring 625 and the spring 4 635, so that the piston on the piston rod 3 633 can form a negative pressure state on the inner surface of the rotating rod 2 632, and under the action of the one-way valve 639 on the right, the hopper 4 is filled with a negative pressure. The viscous liquid feed additive enters the inner cavity of the rotating rod 2 632 through the connecting tube 1 637, and then under the extrusion action of the extrusion ring 625, the piston on the piston rod 3 633 moves to the left, extruding the viscous liquid feed additive in the rotating rod 2 632, and is sprayed out through the action of the one-way valve 639 on the left and the connecting tube 2 638, so that the rotating rod 2 632 rotates one circle to spray the viscous liquid feed additive four times, thereby achieving quantitative spraying, which helps to improve the uniformity and coverage of the coating. Through multiple spraying, it can be ensured that the viscous liquid can be evenly distributed to avoid local excess or deficiency, thereby improving the quality and stability of the coating, and can also improve the coating efficiency, reduce the sagging phenomenon caused by excessive single spraying amount, and improve the consistency and performance of the final product.

[0049] The two one-way valves 639 mentioned above are mature control technology means and equipment in the prior art. In this solution, they are used to control the flow direction of the liquid under the change of the difference between the positive and negative air pressures, and to satisfy that the flow directions of the two one-way valves 639 are distributed in opposite directions. Their internal structure, principle and connection method will not be elaborated again.

[0050] The dual-axis motor 521 mentioned above is a mature driving technology means and equipment in the prior art. In this solution, the couplings on both sides thereof can rotate independently and can stop after rotating to a set number of circles. Its internal structure, connection method and principle will not be elaborated any more.

[0051] The connecting pipe 1 637 and the connecting pipe 2 638 mentioned above are both hard pipes.

[0052] For further information, see Figure 3 and Fig.10 In this embodiment, the drying mechanism 64 includes a threaded ring 641 fixedly connected to the outer surface of the second rotating rod 632, a roller 642 is fixedly connected to the outer surface of the threaded ring 641, a fixing ring 643 is symmetrically connected to the inner surface of the roller 642 and the outer surface of the second rotating rod 632, a steam generator 644 is fixedly installed on the lower part of the inner surface of the outer shell 1, an inlet pipe 646 fixedly connected to the inner surface of the fixing ring 643 located on the right is fixedly connected to the upper end of the steam generator 644, and a discharge pipe 645 is fixedly connected to the right end of the left fixing ring 643, which penetrates and extends to the lower end of the outer shell 1.

[0053] During the implementation process, the rotating rod 632 will drive the roller 642 on the threaded ring 641 to rotate during the rotation process, and the viscous liquid feed additive sprayed from the connecting pipe 638 will be distributed on the outer surface of the roller 642, and then the hydraulic oil will enter the cylinder 629 through the connecting pipe 628 under the action of the electromagnetic valve 6213 and the oil pump 627, so that the scraper 6212 on the piston rod 6210 can be pushed close to the roller 642, so that the scraper 6212 can evenly apply the viscous liquid feed additive on the outer surface of the roller 642. After the application is completed, the hydraulic oil in the cylinder 622 is refluxed under the action of the spring 624 under the action of the electromagnetic valve 6213, so that the extrusion ring 625 is away from the extrusion wheel 634, and then the steam is generated by starting the steam generator 644 and injected into the space formed by the two fixed rings 643 and the roller 642 through the inlet pipe 646. At the same time, under the action of the threaded ring 641, the steam can go in a spiral ring shape. The retention time of steam is increased, and heat is transferred to the drum 642 to dry the viscous liquid feed additive, so that the steam flows along a spiral path after entering, which can effectively improve the heat transfer efficiency of the steam, prompting the steam to form a spiral flow in the drum 642, increasing the contact area between the steam and the drum 642, and enhancing the heat transfer speed, thereby promoting the uniform heating and drying of the viscous liquid feed additive. The spiral flow can also avoid the dead corner area of ​​steam in the drum 642, improve the overall thermal efficiency, and ensure the stability and consistency of the drying process. The steam can evenly heat the viscous liquid feed additive on the outer surface of the drum 642, and quickly increase the temperature of the viscous liquid feed additive through direct heat exchange, and promote the separation of moisture. The temperature and humidity control of the steam can avoid thermal damage to the viscous liquid feed additive caused by excessive temperature, ensuring the stability of the nutritional content and function of the feed additive. The steam drying method helps to improve the drying efficiency, maintain the quality of the viscous liquid feed additive, and reduce energy consumption.

[0054] Secondly, the dried viscous liquid feed additive will still adhere to the outer surface of the drum 642, and then, through the action of the solenoid valve 6213 and the oil pump 627, the scraper 2 6212 on the piston rod 2 6210 will be pushed again close to the outer surface of the drum 642 to scrape the dried viscous liquid feed additive and enter the collection frame 61 under the action of gravity and the annular plate 631.

In this solution, it is used to generate steam and control the temperature of the steam, and its internal structure, principle and connection method are not further explained.
