Description
Technical Field
[0001] This utility model belongs to the field of feed extrusion technology, and more specifically, it relates to an extrusion production device for ultrafine aquatic feed. Background Technology
[0002] Aquatic feed is a specialized feed that provides the nutrients needed for the growth and development of aquatic animals. Its quality directly affects the survival rate, growth rate, and aquaculture efficiency of aquatic animals. To meet the feeding needs of aquatic animals at different growth stages, especially the requirements of juvenile or small aquatic animals for small-particle, highly digestible feed, the feed needs to be processed through extrusion. The extrusion process utilizes a high-temperature, high-pressure environment to fully gelatinize the starch and denature the protein in the feed ingredients. This not only improves the nutrient digestibility of the feed but also enhances the stability of the particles in water, reducing nutrient loss and water pollution.
[0003] As a core component determining the particle size and shape of feed pellets, the die head needs to be frequently replaced according to the specifications of the feed being produced (such as different particle sizes of ultrafine pellets). However, in current extrusion equipment, the connection between the die head and the extruder body (usually the barrel or extrusion chamber) is mostly secured with multiple bolts. When replacing the die head, operators must disassemble the connecting bolts one by one, remove the old die head, and then transport the new die head to the extrusion equipment, align it in the installation position, and tighten the bolts one by one to complete the fixation. This process is not only cumbersome and time-consuming, but also seriously affects production efficiency. Utility Model Content
[0004] The current technology addresses the problem that when changing the die head, operators must disassemble the connecting bolts one by one, remove the old die head, and then transport the new die head to the extrusion device, align it with the installation position, and tighten the bolts one by one to complete the fixation. This process is not only cumbersome and time-consuming, but also seriously affects production efficiency. This invention proposes an ultrafine particle aquatic feed extrusion production device to overcome the above-mentioned technical problems existing in related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to an ultrafine particle aquatic feed extrusion production device, comprising a base, an extrusion component disposed on the top of the base, an anti-clogging component disposed inside the extrusion component, a discharge component disposed at the end of the extrusion component, and a rotating component disposed on the outer surface of the discharge component. The extrusion component is used to extrude the aquatic feed and extrude it from the discharge component. The anti-clogging component is used to prevent the raw material inside the extrusion component from clogging. The discharge component and the rotating component are used to control the particle size after extrusion.
[0007] Furthermore, the puffing assembly includes a first motor, a reducer is drivenly connected to the output shaft of the first motor, a hopper is fixedly installed on the outer surface of the reducer, a hopper is fixedly connected to the outer surface of the hopper, an extrusion screw is drivenly connected to the outer surface of the reducer, the extrusion screw is rotatably connected to the inside of the hopper, a heat-conducting pipe is fixedly connected to the outer surface of the hopper, and both the reducer and the hopper are fixedly installed on the top of the base.
[0008] Furthermore, the anti-clogging component includes a support, which is fixedly installed on the top of the base. A second motor is fixedly installed on the top of the support. A first pulley is fixedly installed on the output shaft of the second motor. A belt is installed on the outer surface of the first pulley.

A round rod is fixedly connected to the outer surface of the rotating shaft. Both the rotating shaft and the round rod are rotatably connected inside the hopper.
[0009] Furthermore, the discharge assembly includes a connecting seat, which is fixedly installed on the outer surface of the hopper. A spring is fixedly connected inside the connecting seat, and a sliding seat is fixedly connected to the end of the spring. The sliding seat is slidably connected inside the connecting seat.
[0010] Furthermore, the rotating assembly includes a bracket, which is fixedly mounted on the top of the base. A rotating frame is rotatably connected to the outer surface of the bracket, and a die head is slidably connected inside the rotating frame.

[0011] Furthermore, a slide rail is fixedly connected to the top of the base, a sliding frame is slidably connected to the outer surface of the slide rail, and a discharge plate is fixedly connected to the top of the sliding frame.
[0012] Furthermore, a lifting lug is fixedly connected to the top of the base.
[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model connects the discharge component and the rotating component. The extrusion component pushes the aquatic feed to move and squeeze it out from the discharge component and the rotating component. After the rotating component is separated from the discharge component, the rotating component is pushed to rotate. By selecting a part with a suitable aperture on the outer surface of the rotating component to connect with the discharge component, the size of the aquatic feed particles can be changed. Moreover, the rotating component is installed near the discharge component, making it easy to install, disassemble and replace.
[0015] 2. This utility model uses the connection between the spring and the sliding seat. When the die head is connected to the connecting seat, it pushes the sliding seat to move and compresses the spring. When the die head is separated from the connecting seat, the die head no longer compresses the spring, and the spring pushes the sliding seat to reset, so that the sliding seat fills the gap of the connecting seat and prevents foreign objects from entering the gap of the connecting seat and affecting its normal connection with the die head.

Therefore, they should not be construed as limitations on the utility model.
[0031] Please see Figures 1-9 As shown, this utility model is an ultrafine particle aquatic feed extrusion production device, including a base 1, an extrusion component 2 is provided on the top of the base 1, an anti-clogging component 3 is provided inside the extrusion component 2, a discharge component 4 is provided at the end of the extrusion component 2, and a rotating component 5 is provided on the outer surface of the discharge component 4.

[0032] After pouring the raw materials for aquatic feed into the extrusion component 2 at the top of the base 1, activate the anti-blocking component 3.

[0033] This invention connects the discharge assembly 4 and the rotating assembly 5. The extrusion assembly 2 pushes the aquatic feed to move and squeeze it out from the discharge assembly 4 and the rotating assembly 5. After separating the rotating assembly 5 from the discharge assembly 4, the rotating assembly 5 is pushed to rotate.

The rotating extrusion screw 205 crushes the raw materials of aquatic feed and moves the crushed raw materials. The heating equipment is connected through the heat conduction pipe 206 on the outer surface of the hopper 203 to heat and expand the crushed raw materials in the hopper 203. The expanded aquatic feed is carried out by the extrusion screw 205.
[0036] In one embodiment, the anti-blocking component 3 includes a support 301, which is fixedly installed on the top of the base 1. A second motor 302 is fixedly installed on the top of the support 301. A first pulley 303 is fixedly installed on the output shaft of the second motor 302. A belt 304 is installed on the outer surface of the first pulley 303. A second pulley 305 is driven to the first pulley 303 through the belt 304.

[0038] In one embodiment, the discharge component 4 includes a connecting seat 401, which is fixedly installed on the outer surface of the hopper 203. A spring 402 is fixedly connected inside the connecting seat 401, and a sliding seat 403 is fixedly connected to the end of the spring 402. The sliding seat 403 is slidably connected inside the connecting seat 401.
[0039] In one embodiment, the rotating component 5 includes a bracket 501, which is fixedly mounted on the top of the base 1. A rotating frame 502 is rotatably connected to the outer surface of the bracket 501. A die head 503 is slidably connected inside the rotating frame 502. The die head 503 is threadedly connected to the connecting seat 401. A discharge hole 504 is provided on the outer surface of the die head 503.

[0042] By pushing the discharge plate 8 through the sliding between the sliding frame 7 and the slide rail 6, the position of the discharge plate 8 can be changed, so that the discharge plate 8 avoids the rotating frame 502 and prevents the discharge plate 8 from obstructing the rotation of the rotating frame 502.
[0043] In one embodiment, the base 1 is fixedly connected to a lug 9 at its top.
[0044] By passing the lifting equipment through the lifting lug 9, the base 1 can be lifted, facilitating the transfer of the device.
[0045] Through the above technical solutions, 1. By connecting the discharge component 4 and the rotating component 5, the extrusion component 2 pushes the aquatic feed to move so that it is extruded from the discharge component 4 and the rotating component 5. After separating the rotating component 5 from the discharge component 4, the rotating component 5 is pushed to rotate. By selecting a part with a suitable aperture on the outer surface of the rotating component 5 to connect with the discharge component 4, the size of the aquatic feed particles can be changed. Moreover, the rotating component 5 is installed near the discharge component 4, making it easy to install, disassemble, and replace. 2. By connecting the spring 402 and the sliding seat 403, when the die head 503 is connected to the connecting seat 401, it pushes the sliding seat 403 to move. The sliding seat 403 compresses the spring 402. When the die head 503 is separated from the connecting seat 401, the die head 503 no longer compresses the spring 402. The spring 402 pushes the sliding seat 403 to reset, so that the sliding seat 403 fills the gap of the connecting seat 401, preventing debris from entering the gap of the connecting seat 401 and affecting its normal connection with the die head 503.
