Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a liquid feed additive feeding device. Background Technology

[0002] A liquid feed additive feeding device is a device used in the production process of liquid feed to add additives to the liquid feed, thereby mixing the additives with the liquid feed and improving the nutritional value and quality of the liquid feed.

[0003] Existing additive feeding devices for liquid feed production typically consist of a control system, a mixing tank, a drive motor, a mixing mechanism, a feeding pipe, and a discharge pipe. During the feeding operation, the additive is first injected into the feeding pipe through the inlet, and then introduced into the mixing tank. When the additive and the liquid feed in the tank are mixed, the drive motor is started, and the motor controls the mixing mechanism to stir the liquid feed and additive, ensuring the additive is fully mixed in the liquid feed. After stirring is complete, the liquid feed is discharged from the discharge pipe, thus completing the liquid feed production process.

[0004] However, in the above process, various types of additives are added to the liquid feed, some in liquid form and others in powder form. When powdered additives are added, because all the additives fall from the opening of the feeding pipe, the powdered additives tend to land in a concentrated area on the liquid feed. This large amount of powdered additive coming into contact with the liquid feed can cause it to stick together, resulting in clumping. This can make it difficult for the mixing mechanism to thoroughly mix the additives and liquid feed, severely affecting the mixing efficiency. Therefore, we propose a liquid feed additive feeding device to effectively solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a liquid feed additive feeding device to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a liquid feed additive feeding device, including a feeding pipe set at the top of a mixing tank, the feeding pipe having a through structure, a dispersion cover being rotatably sleeved at the bottom end of the feeding pipe, the dispersion cover having a cylindrical structure without a top cover, and a plurality of circumferentially arranged dispersing ports being opened on the side wall of the dispersion cover.

[0007] It also includes a drive mechanism, which is located at the top inside the mixing tank and is used to control the rotation of the dispersion hood.

[0008] Optionally, the bottom sidewall of the feeding tube is provided with a number of notches, and the number of notches corresponds one-to-one with the number of material dispensing ports; when the dispersing cover rotates outside the feeding tube, the material dispensing ports and the notches are aligned or staggered.

[0009] Optionally, the inner wall of the dispersion hood is rotatably connected to the outer wall of the feeding pipe via a sealed bearing, and the bottom of the feeding pipe is in contact with the inner bottom wall of the dispersion hood.

[0010] Optionally, a toothed ring is fixedly sleeved on the outer side of the dispersion cover, and the driving mechanism is used to drive the toothed ring to rotate so as to drive the dispersion cover to rotate.

[0011] Optionally, the drive mechanism includes a servo motor disposed inside the mixing tank, and a drive gear is fixedly mounted on the output end of the servo motor, the drive gear meshing with the gear ring.

[0012] Optionally, a guide portion is fixedly provided on the inner bottom wall of the dispersion hood, the upper surface of the guide portion is a spherical shape with an upward convexity, and the guide portion is located inside the feeding pipe.

[0013] Compared with the prior art, the present invention provides a liquid feed additive feeding device, which has the following beneficial effects:

[0014] 1. This utility model sets a rotatable dispersion hood at the outlet of the feeding pipe, and uses circumferentially arranged dispersion ports to discharge the additives. By controlling the rotation of the dispersion hood, the additives in the feeding pipe can be thrown out from several dispersion ports, so that the falling position of the additives is dispersed, avoiding the powder additives from falling in one place and causing agglomeration, thus improving the mixing efficiency.

[0015] 2. This utility model has several notches at the opening of the feeding pipe that correspond one-to-one with the dispersing port. When feeding is not required, the dispersing cover can be rotated by a servo motor at a certain angle to make the notches and dispersing ports misaligned, so that the additive cannot be thrown out of the feeding pipe, avoiding excessive additive addition that would affect the quality of the feed. At the same time, it can also realize the operation of intermittent feeding, which makes it easy to control the amount of additive added. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 6 A liquid feed additive feeding device includes a feeding pipe 101 disposed at the top of a mixing tank 1. The feeding pipe 101 has a through-type structure, and a dispersion cover 2 is rotatably fitted at the bottom end of the feeding pipe 101. The dispersion cover 2 has a cylindrical structure without a top cover, so that the additive in the feeding pipe 101 will first fall into the inner side of the dispersion cover 2 for storage. Several circumferentially arranged dispensing ports 201 are opened on the side wall of the dispersion cover 2, so that the additive falling into the inner side of the dispersion cover 2 can be dispersed from the surrounding dispensing ports 201, thereby dispersing the drop position of the additive, avoiding the accumulation of powdered additives and causing agglomeration, and improving the mixing efficiency.

[0025] This embodiment also includes a drive mechanism 4, which is located at the top of the mixing tank 1. The drive mechanism 4 is used to control the rotation of the dispersion hood 2 so that the additives inside the dispersion hood 2 can be thrown out as the dispersion hood 2 rotates at high speed.

[0026] Furthermore, the bottom sidewall of the feeding pipe 101 is provided with several notches 1011, and the notches 1011 correspond one-to-one with the dispensing ports 201. When the dispersion hood 2 rotates outside the feeding pipe 101, the dispensing ports 201 and the notches 1011 are aligned or staggered, so that when the dispensing ports 201 and the notches 1011 are aligned, the additive in the feeding pipe 101 can come out from the dispensing ports 201; when the dispensing ports 201 and the notches 1011 are staggered, the additive in the feeding pipe 101 cannot come out from the dispensing ports 201. Thus, the dispersion hood 2 can achieve intermittent feeding when rotating, and when no more additives are needed, the dispensing ports 201 can be closed, which makes it convenient for the staff to control the amount of additives added.

[0027] In this embodiment, the inner wall of the dispersion hood 2 is rotatably connected to the outer wall of the feeding pipe 101 via a sealing bearing 3, so that the dispersion hood 2 and the feeding pipe 101 can still maintain a sealed state when the dispersion hood 2 rotates outside the feeding pipe 101. This not only improves the stability of the dispersion hood 2 during rotation, but also prevents the additive from leaking from the connection between the dispersion hood 2 and the feeding pipe 101. The bottom of the feeding pipe 101 is fitted to the inner bottom wall of the dispersion hood 2, so that when the notch 1011 and the dispensing port 201 are misaligned and the dispensing port 201 is closed, the additive in the feeding pipe 101 will not leak to the dispensing port 201.

[0028] Specifically, a toothed ring 202 is fixedly sleeved on the outer side of the dispersion cover 2, and the driving mechanism 4 is used to drive the toothed ring 202 to rotate so as to drive the dispersion cover 2 to rotate.

[0029] The drive mechanism 4 includes a servo motor 401 installed in the mixing tank 1. The output end of the servo motor 401 is fixedly fitted with a drive gear 402. The drive gear 402 meshes with the gear ring 202 so that when the servo motor 401 controls the drive gear 402 to rotate, the drive gear 402 will drive the gear ring 202 to rotate, and the gear ring 202 will drive the dispersion cover 2 to rotate, thereby causing the additive in the feeding pipe 101 to be thrown out and dispersed to different areas.

[0030] Furthermore, a guide portion 203 is fixedly provided on the inner bottom wall of the dispersion hood 2. The upper surface of the guide portion 203 is a spherical shape with an upward bulge, and the guide portion 203 is located inside the feeding pipe 101, so that the additive in the feeding pipe 101 will fall along the upper surface of the guide portion 203 to the surrounding area, and finally fall into the mixing tank 1 from the openings 1011 and the dispersing port 201 around the perimeter to mix with the liquid feed.

[0031] It should be noted that a mounting bracket 102 is fixedly installed inside the mixing tank 1, and the servo motor 401 is mounted on the mounting bracket 102. This allows the mounting bracket 102 to not only provide support for the servo motor 401 but also to protect it, preventing additives and other substances from affecting the operation of the servo motor 401. Meanwhile, a controller 5 is located on the outside of the mixing tank 1, and the servo motor 401 is electrically connected to the controller 5. This allows operators to control the output rate and frequency of the servo motor 401, facilitating the adjustment and control of the method and amount of additives added.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
