Description

Technical Field

[0001] This utility model belongs to the field of fish feed production technology, specifically a dehydrator for fish feed production. Background Technology

[0002] Dehydrating fish feed can prevent mold growth, extend shelf life, reduce weight and lower transportation costs, while also preserving nutrients, reducing pellet breakage, ensuring feed quality, and meeting the needs of aquaculture for feed stability and safety.

[0003] However, existing technologies for fish feed dehydration have the following problems: First, the air distribution plate is easily clogged by feed powder and sticky impurities, requiring frequent manual disassembly and cleaning, which not only consumes manpower but also requires machine downtime, affecting production efficiency; Second, some equipment (such as drum dehydrators) or uneven vibration causes severe friction and compression of feed particles, resulting in a high breakage rate and affecting the shape and quality of the finished product; Third, vibration and impact are transmitted to the workshop floor, which can easily interfere with the operation of surrounding equipment and generate loud noise, failing to meet the requirements of environmentally friendly workshops and affecting the working environment of operators. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a dehydrator for fish feed production, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dehydrator for fish feed production, comprising a base, a plurality of rubber composite damping springs fixedly connected to the upper end of the base, a bracket fixedly connected to the top of the rubber composite damping springs, a bellows fixedly connected to the inner wall of the bracket, an air inlet duct connected to one end of the bellows, an air distribution plate fixedly connected to the top of the bellows, a dehydration chamber fixedly connected to the top of the air distribution plate, a feeding chamber connected to one end of the dehydration chamber, a discharge hopper connected to the end of the dehydration chamber away from the feeding chamber, an air outlet opened at the top of the dehydration chamber, a drive mechanism provided inside the base, and a cleaning mechanism provided inside the bellows.

[0006] As a further embodiment of this utility model: the driving mechanism includes a dual-axis motor fixedly installed in the base, and cranks are coaxially fixedly connected to both output shafts of the dual-axis motor. A pin is fixed to the end of the crank away from the output shaft, and a rocker arm is rotatably sleeved on the pin arm. The free end of the rocker arm is rotatably connected to the bottom of the bracket.

[0007] As a further embodiment of this utility model: two guide rods are fixedly connected inside the base, and the guide rods pass through the bracket and are slidably connected to the bracket.

[0008] As a further embodiment of this utility model: the cleaning mechanism includes a gear and a reciprocating screw rotatably connected inside the air box. The gear and the reciprocating screw are connected by a one-way bearing. A cleaning scraper is threaded onto the reciprocating screw. A rack is fixedly connected inside the base. A slag baffle is fixedly connected above the reciprocating screw inside the air box.

[0009] As a further embodiment of this utility model: the upper end of the rack penetrates the bottom wall of the air box, and the rack meshes with the gear.

[0010] As a further embodiment of this utility model: the brush part of the cleaning scraper is in contact with the bottom of the air cloth plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Automatic cleaning of the air distribution plate without additional power and easy maintenance: The vibration power of the drive mechanism generates reciprocating rotation through the meshing of gears and fixed racks. Then, the reciprocating screw is driven to rotate in one direction through the one-way bearing, which in turn drives the cleaning scraper to scrape along the bottom of the air distribution plate. This can remove residual fish feed powder or sticky impurities in the openings of the air distribution plate in real time, avoiding blockage of the openings and affecting airflow distribution. Moreover, no additional cleaning motor is required, which simplifies the structure and reduces the frequency of manual disassembly and maintenance. 2. The dual-shaft motor, with cranks, pins, and rockers on both output shafts, drives the support frame to vibrate synchronously on both sides. Simultaneously, two vertical guide rods restrict the support frame's movement to only the vertical direction, preventing horizontal deviation or swaying. Compared to drum dewatering machines, this reduces particle breakage. 3. Significant vibration reduction and noise reduction effect, suitable for workshop production environment: The rubber composite vibration damping spring between the base and the support can effectively absorb vibration impact. On the one hand, it can reduce the vibration transmission of the equipment to the workshop floor and avoid affecting the normal operation of surrounding equipment; on the other hand, it can significantly reduce the operating noise of the equipment, meet the environmental noise standards of the workshop, and effectively improve the working environment of the operators.

Detailed Implementation

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figure 1 - Figure 6 As shown, this utility model provides a technical solution: A dehydrator for fish feed production includes a base 1. Several rubber composite damping springs 2 are fixedly connected to the upper end of the base 1. A bracket 3 is fixedly connected to the top of the rubber composite damping springs 2. A bellows 4 is fixedly connected to the inner wall of the bracket 3. An air inlet duct 5 is connected to one end of the bellows 4. An air distribution plate 6 is fixedly connected to the top of the bellows 4. A dehydration chamber 7 is fixedly connected to the top of the air distribution plate 6. A feeding chamber 8 is connected to one end of the dehydration chamber 7. A discharge hopper 9 is connected to the end of the dehydration chamber 7 away from the feeding chamber 8. An air outlet 10 is opened on the top of the dehydration chamber 7. A drive mechanism is installed inside the base 1. A cleaning mechanism is installed inside the bellows 4. Specifically, the material enters the air distribution plate 6 inside the dehydration chamber 7 from the feeding hopper 8. The air inlet duct 5 introduces hot air into the air box 4. The airflow penetrates the material layer evenly through the openings of the air distribution plate 6, carrying away the moisture in the fish feed. The hot and humid air is discharged from the air outlet 10 at the top of the dehydration chamber 7. At the same time, the drive mechanism drives the support 3, the air box 4, and the dehydration chamber 7 to vibrate as a whole, so that the material on the air distribution plate 6 is in a fluidized state. During this process, the rubber composite damping spring 2 between the base 1 and the support 3 expands and contracts with the vibration, absorbing the vibration impact energy and reducing the vibration transmission and operating noise of the equipment to the ground. The cleaning mechanism cleans the bottom of the air distribution plate 6 simultaneously. Finally, the dehydrated material is discharged from the discharge hopper 9. The drive mechanism includes a dual-axis motor 11 fixedly installed in the base 1. Both output shafts of the dual-axis motor 11 are coaxially fixedly connected to cranks 12. A pin 13 is fixed to the end of the crank 12 away from the output shaft. A rocker arm 14 is rotatably sleeved on the outside of the pin 13. The free end of the rocker arm 14 is rotatably connected to the bottom of the bracket 3. Two guide rods 15 are fixedly connected in the base 1. The guide rods 15 pass through the bracket 3 and are slidably connected to the bracket 3. Specifically, after the dual-shaft motor 11 starts, the cranks 12 on both sides rotate synchronously, driving the rocker arm 14 to reciprocate through the pin shaft 13. Since the free end of the rocker arm 14 is rotatably connected to the bottom of the support 3, it drives the support 3 to vibrate up and down along the guide rod 15. The guide rod 15 restricts the vibration direction of the support 3, ensuring that the support 3 and the bellows 4, air distribution plate 6, and dewatering chamber 7 above it vibrate stably, so that the material is uniformly fluidized on the air distribution plate 6, thereby improving the dewatering rate. The cleaning mechanism includes a gear 16 and a reciprocating screw 17 rotatably connected inside the air box 4. The gear 16 and the reciprocating screw 17 are connected by a one-way bearing. A cleaning scraper 18 is threaded onto the reciprocating screw 17. A rack 19 is fixedly connected inside the base 1. A slag baffle 20 is fixedly connected inside the air box 4 above the reciprocating screw 17. The upper end of the rack 19 penetrates the bottom wall of the air box 4 and meshes with the gear 16. The brush part of the cleaning scraper 18 is in contact with the bottom of the air distribution plate 6. Specifically, when the bellows 4 vibrates up and down with the support 3, the gear 16 inside it moves up and down synchronously. The rack 19, which is fixedly connected to the base 1, continuously meshes with the gear 16, thereby driving the gear 16 to rotate back and forth. The reciprocating rotation of the gear 16 is transmitted to the reciprocating screw 17 through a one-way bearing, causing the reciprocating screw 17 to rotate continuously in one direction. The reciprocating screw 17 drives the cleaning scraper 18 to move back and forth along the bottom of the air distribution plate 6 through thread transmission. Its brush part is closely attached to the air distribution plate 6, removing residual materials in the opening in real time to prevent blockage. The slag baffle 20 is located directly above the reciprocating screw 17, which can prevent residual materials generated after the brush cleans the air distribution plate 6 from falling into the spiral groove of the reciprocating screw 17 and causing the balls inside the nut to jam.

[0016] The working principle of this utility model is as follows: First, start the device and introduce hot airflow: send the fish feed to be dehydrated from the feed hopper 8 into the air distribution plate 6 in the dehydration hopper 7, and at the same time introduce hot airflow into the air box 4 through the air inlet duct 5. The hot airflow penetrates the fish feed material layer evenly upward through the opening of the air distribution plate 6. When the dual-shaft motor 11 is started, its two output shafts drive the crank 12 to rotate synchronously. The crank 12 drives the rocker arm 14 to swing back and forth through the pin 13. Since the free end of the rocker arm 14 is rotatably connected to the bottom of the bracket 3, and the bracket 3 slides along the guide rod 15 in the base 1, the bracket 3 and the bellows 4, air distribution plate 6, and dehydration chamber 7 above it will vibrate stably in the vertical direction. During this process, the rubber composite damping spring 2 between the base 1 and the bracket 3 expands and contracts with the vibration, absorbs the vibration impact energy, reduces the vibration transmission of the equipment to the ground and the operating noise. Under the action of vibration, the fish feed on the air distribution plate 6 is in a suspended fluidized state, which greatly increases the contact area with the hot airflow, accelerates the evaporation of water, and improves the dehydration efficiency. When the bellows 4 vibrates up and down with the support 3, the gear 16 inside the bellows 4 moves up and down synchronously, while the rack 19 fixed inside the base 1 always meshes with the gear 16, driving the gear 16 to rotate back and forth; the reciprocating rotation of the gear 16 is transmitted to the reciprocating screw 17 through the one-way bearing, so that the reciprocating screw 17 rotates continuously in only one direction; the reciprocating screw 17 drives the cleaning scraper 18 to move back and forth along the bottom of the air distribution plate 6 through the threaded transmission, and its brush part is closely attached to the air distribution plate 6 to scrape off the fish feed powder or sticky impurities remaining in the opening of the air distribution plate 6 in real time, so as to avoid the opening being blocked and affecting the airflow distribution; the slag baffle 20 is located directly above the reciprocating screw 17, which can prevent the residual material generated after the brush cleans the air distribution plate 6 from falling into the spiral groove of the reciprocating screw 17 and causing the ball inside the nut to jam; Finally, with the continuous action of the hot airflow and the stable fluidization of the material, the moisture content in the fish feed gradually decreases to the target value. Under the action of vibration thrust, the dehydrated fish feed is discharged from the discharge hopper 9 at the end of the dehydration chamber 7 away from the feed chamber 8, thus completing the fish feed dehydration operation. Throughout the process, the cleaning mechanism operates synchronously to ensure that the air distribution plate 6 remains unobstructed and to ensure the stable progress of subsequent dehydration operations.

[0017] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
