Description

Technical Field

[0001] The utility model relates to the technical field of aquatic feed production equipment, in particular to an aquatic feed particle screening device. Background Art

[0002] Aquatic feed is generally made from fish bones, shrimp heads, shells, etc. In the production of aquatic feed, whether it is extrusion or pelleting, the feed is required to form particles of a certain size. However, if there are too many fine powders in the aquatic feed, it will affect the water quality when it is added to the water body. If there are too many large particles in the aquatic feed, it will affect the feeding effect. Therefore, corresponding screening equipment is needed to screen the aquatic feed particles.

[0003] After searching, the existing Chinese patent with publication number CN202022684654.4 discloses a submerged aquatic feed granulation and screening device, which realizes the transportation of granular feed by rotating a spiral feed rod. During the transportation process, the first curved screen, the second curved screen or the third curved screen realizes the screening of the granular feed. Since the mesh size of the first curved screen is smaller than the mesh size of the second curved screen, and the mesh size of the second curved screen is smaller than the mesh size of the third curved screen, it is possible to collect feeds of different particle sizes without replacing the screen plate every time.

[0004] The above technical solution has the following drawbacks: although such an aquatic feed pellet screening device can drive the aquatic feed pellets through the curved screen during the conveying process by means of a spiral feed rod, in actual use, the hardness of the aquatic feed pellets just produced is relatively low, and the large aquatic feed pellets are easily broken by using bolt blades to convey the aquatic feed pellets on the screen, resulting in an increase in the powder of the aquatic feed pellets and a decrease in the number of qualified finished pellets. Therefore, an aquatic feed pellet screening device is proposed, which can not only classify and screen the aquatic feed pellets according to needs and discharge them separately, but also effectively reduce the breakage of the aquatic feed pellets and improve the yield rate. In addition, the screen is easy to replace according to actual needs, so that when producing aquatic feed pellets of different particle sizes, the screen of the required particle size can be replaced as needed, thereby having better applicability.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

Moreover, the screen can be easily replaced according to actual needs, so that when producing aquatic feed particles of different particle sizes, the screen of the required particle size can be replaced as needed, thereby having better applicability.

[0008] The utility model solves the above technical problems as follows: an aquatic feed particle screening device comprises a screening box, a screening frame, and a supporting base, the screening box is fixedly connected to an aquatic feed particle inlet hopper, the inner wall of the screening box is evenly fixedly installed with a screen placement frame and a material guide base, the screening frame is fixedly installed with a screening mesh and a connecting strip, the screening frame can be stuck in the screen placement frame and positioned by a pin, and the apertures of multiple screening meshes decrease from top to bottom, the top of the material guide base is evenly fixedly installed with a buffer spring, the top of the buffer spring is fixedly connected with a material guide plate, the screening box is fixedly connected with a material guide pipe, the material guide pipe is fixedly connected with a material guide hose, the top of the support base is evenly fixedly installed with a spring base, the top of the spring base is fixedly connected to the screening box, the bottom of the screening box is fixedly connected with a vibration motor, the bottom of the support base is provided with a through hole corresponding to the vibration motor, and the screening box is provided with an inspection door.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a No. 1 dust cover is fixedly installed at the gap between the material guide base and the material guide plate. The No. 1 dust cover wraps the buffer spring, and the buffer spring can be protected by the No. 1 dust cover to increase its service life.

[0011] Furthermore, a No. 2 dust cover is installed at the gap between the support base and the screening box. The No. 2 dust cover wraps the spring base, and the spring base can be protected by the No. 2 dust cover to increase its service life.

[0012] Furthermore, the top of the material guide base is an inclined surface, and the material guide plate is arranged obliquely, so that the aquatic feed particles under the screen can be transported to the end of the next screening net under the guiding action of the material guide plate.

[0013] Furthermore, the screen placement frame and the screening frame are both arranged at an inclination, so that the aquatic feed particles can fall on the top of the screening net and be screened during the movement.

[0014] Furthermore, the guide plate is made of rubber material so that the aquatic feed particles that fall through the sieve can be cushioned.

[0015] Furthermore, the outer wall of the screening box is fixedly connected to a limit strip, and the bottom of the support base is provided with a limit groove corresponding to the limit strip, so that the support base can be used for the screening box.

[0018] 1. Open the inspection door and select a screening frame with a screening mesh of appropriate aperture according to the diameter requirements of the aquatic feed particles. Insert the connecting strip of the screening frame into the screen placement frame and position it with the pins. The screening mesh can then be stably placed in the screening box to screen the aquatic feed particles. This installation structure is convenient for disassembly and replacement as needed.

[0019] 2. Aquatic feed particles are introduced into the screening box from the aquatic feed particle inlet hopper. Starting the vibration motor can drive the screening box to vibrate on the top of the spring base. The inclined screening net can quickly screen the aquatic feed particles under the vibration condition. The screened aquatic feed particles can pass through the screening net and be transferred to the top of the guide plate. When the aquatic feed particles are screened, the buffer spring at the gap between the guide base and the guide plate can buffer the aquatic feed particles, allowing the aquatic feed particles to move smoothly to the end of the next screening net for further screening until the aquatic feed powder passes through the bottom screening net and is transferred to the screening box. The screened aquatic feed particles and aquatic feed powder can be discharged from multiple groups of guide pipes after screening.

[0020] 3.
