[0002] The concentrated crystallization process of feed additives is to convert liquid feed additive raw materials into solid crystal forms through a series of technological steps for easy storage, transportation and use.

[0003] In the existing concentrated crystallization device for producing feed additives, after the liquid raw material of the feed additive is introduced into the crystallization tank, hot air is then introduced into the crystallization tank to concentrate and crystallize the liquid raw material. However, since the liquid raw material stands still in the tank and has a small contact area with the hot air, the concentrated crystallization efficiency is low. Moreover, after the liquid raw material is concentrated and crystallized, it is easy to adhere to the inner wall of the crystallization tank and is not easy to discharge.

[0004] Therefore, a concentrated crystallization device for producing feed additives has now been developed, which can enable the liquid raw material to fully contact with the hot air, improve the concentrated crystallization efficiency, and at the same time can scrape the crystals off the kettle body. Content of the Utility Model

Detailed implementation manners

[0019] Although the present utility model may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present utility model. Those of ordinary skill in the art will recognize that terms such as "above", "below", "upward", "downward", etc. are used to describe the attached drawings and do not represent a limitation on the scope of the present utility model defined by the appended claims. Any numerical labels such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present utility model in any way.

[0020] A concentrated crystallization device for producing feed additives, as Figure 1 and Figure 2 shown, includes support feet 1, a discharge cover 2, a kettle body 3, a steam outlet pipe 4, a solution inlet pipe 5, a hot air inlet pipe 6, and a rotating mechanism 7. There are three support feet 1, and a kettle body 3 is connected between the upper sides of the support feet 1. The lower part of the kettle body 3 is an arc structure to facilitate discharging. A discharge cover 2 is rotatably connected to the lower side of the kettle body 3. A steam outlet pipe 4 is connected to the upper right side of the kettle body 3. A solution inlet pipe 5 is connected to the upper right side of the upper part of the kettle body 3. A hot air inlet pipe 6 is connected to the upper left side of the kettle body 3. A rotating mechanism 7 is provided on the kettle body 3.

[0021] As Figure 1 and Figure 3As shown in the figure, the rotating mechanism 7 includes a motor 71, a connecting pipe 72, a first connecting sleeve 73, a first spring 74, a sliding rod 75, a wall scraper 76, a solution spray pipe 77, a second spring 78, and a scraping knife 79. A motor 71 is connected to the upper side of the middle part of the kettle body 3. A connecting pipe 72 is connected to the output shaft of the motor 71. The upper part of the connecting pipe 72 is provided with a liquid inlet groove for facilitating liquid inlet. The connecting pipe 72 is rotatably connected to the kettle body 3. A first connecting sleeve 73 is connected to the upper part of the connecting pipe 72. Three sliding rods 75 are slidably connected to the first connecting sleeve 73. First springs 74 are connected between the sliding rods 75 and the first connecting sleeve 73 respectively. Wall scrapers 76 are connected to the outer sides of the sliding rods 75. The wall scrapers 76 are all in contact with the kettle body 3. A plurality of solution spray pipes 77 are connected to the outer side of the connecting pipe 72. A scraping knife 79 is slidably connected to the lower part of the connecting pipe 72. A second spring 78 is connected between the scraping knife 79 and the connecting pipe 72. The scraping knife 79 is in contact with the kettle body 3.

[0022] When using the present utility model, first, the liquid raw material of the feed additive is introduced into the solution inlet pipe 5. The liquid raw material enters the connecting pipe 72 through the liquid inlet groove, and then the motor 71 is started to drive the connecting pipe 72 to rotate, so that the liquid raw material is sprayed from the solution spray pipe 77 into the kettle body 3. The supporting feet 1 support the kettle body 3. While the liquid raw material is being sprayed, hot air is introduced into the kettle body 3 through the hot air inlet pipe 6 to concentrate and crystallize the liquid raw material. The steam evaporated from the liquid raw material is discharged from the steam outlet pipe 4. After the liquid raw material is concentrated and crystallized, the discharge cover 2 is opened to discharge the crystallized feed additive. While the connecting pipe 72 rotates, it drives the first connecting sleeve 73 to rotate, so that the wall scrapers 76 and the scraping knife 79 move on the kettle body 3 to scrape off the attached crystals. Due to the acting force of the first spring 74 and the second spring 78, the wall scrapers 76 and the scraping knife 79 always remain in contact with the kettle body 3, thereby playing a role in enabling the liquid raw material to fully contact with the hot air, improving the concentration and crystallization efficiency, and at the same time being able to scrape the crystals off the kettle body 3.

[0023] As Figure 1 and Figure 4 shown in the figure, it further includes a condensation mechanism 8. The condensation mechanism 8 includes a condensation box 81, a third spring 82, a piston rod 83, a second connecting sleeve 84, a condensation plate 85, and a condensate outlet pipe 86. The condensation box 81 is connected to the lower right side of the kettle body 3. The steam outlet pipe 4 is connected to the condensation box 81. A second connecting sleeve 84 is connected to the upper part inside the condensation box 81. A piston rod 83 is slidably connected to the second connecting sleeve 84. A third spring 82 is connected between the piston rod 83 and the second connecting sleeve 84. The piston rod 83 is in contact with the steam outlet pipe 4. A condensation plate 85 is connected inside the condensation box 81. The condensation plate 85 is located below the second connecting sleeve 84. The condensate outlet pipe 86 is connected to the lower side of the condensation box 81.

[0024] By using the condensation mechanism 8 of the present device, the steam can be condensed. The piston rod 83 blocks the steam outlet pipe 4 under the action of the third spring 82, prolonging the residence time of the hot air and improving the crystallization efficiency of the raw materials. After a certain amount of steam is generated in the kettle body 3, the steam pushes the piston rod 83 to move within the second connecting sleeve 84, causing the piston rod 83 to disengage from the steam outlet pipe 4. The third spring 82 is compressed and contracted. Then, the steam enters the condensation box 81 from the steam outlet pipe 4, and the steam is condensed by the condensation plate 85. The condensed water after condensation is discharged from the condensed water outlet pipe 86, thus playing the role of being able to condense the steam and reducing the environmental pollution to the surrounding area.

[0025] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
