Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a fish, shrimp and crab feed dryer. Background Technology

[0002] In the processing of fish, shrimp and crab feed, the fish is first sterilized and pre-cooked at high temperature to make fish paste. Then, mineral-based natural binders, flour, corn flour, high-gluten flour and other ingredients are sterilized and pre-cooked at high temperature. The fish paste is then mixed with the cooked binders, flour, corn flour and high-gluten flour, and probiotics and vitamins are added. After cold treatment, the feed is made into pellets. After the feed pellets are made, in order to reduce the moisture content in the feed pellets and improve the stability and shelf life of the feed, they need to be dried.

[0003] A search revealed that the Chinese patent "A Feed Dryer" (authorization announcement number "CN215447326U") involves adding the feed to be dried to one end of a conveyor belt through the feed inlet and feed pipe. The conveyor belt then evenly distributes the feed across the entire belt. After the feed is distributed, the feed on the conveyor belt continues to dry. By spreading the feed evenly on the conveyor belt, the contact area between the feed particles and the hot air blown by the hot air blower is increased, thereby achieving more uniform drying of the feed, improving the drying effect, and ultimately improving the quality of the feed.

[0004] While the aforementioned application can dry the feed by laying it on a conveyor belt, the feed is in a static state during the drying process. When drying the feed from below the conveyor belt, the feed in contact with the conveyor belt receives more heat, while the feed away from the conveyor belt receives less heat, thus affecting the uniformity of feed drying.

[0005] Therefore, a fish, shrimp and crab feed dryer is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a fish, shrimp and crab feed dryer to solve the above-mentioned problems. It improves the problem that when the feed is dried from below the conveyor belt, the feed in contact with the conveyor belt receives more heat, while the feed far from the conveyor belt receives less heat, thus affecting the uniformity of feed drying.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a fish, shrimp, and crab feed dryer, comprising: a drying chamber, wherein two circular rollers are rotatably connected to the inner wall of the drying chamber, and a conveyor belt is drivingly connected between the two circular rollers; a drying mechanism, wherein the drying mechanism includes a drive assembly and a cold air fan installed on one side of the drying chamber, a fixed pipe is fixedly connected to the inner wall of the drying chamber, and a plurality of evenly distributed exhaust pipes are connected to the surface of the fixed pipe, one end of the fixed pipe is connected to the air outlet of the cold air fan, and a sliding frame is slidably connected to the inner wall of the drying chamber, the bottom end of the sliding frame is in contact with the surface of the conveyor belt, the two sides of the sliding frame form an angle with the vertical plane, and an arc-shaped groove is provided at the top end of the sliding frame.

[0008] Preferably, the drying mechanism further includes a mounting plate fixedly connected to one side of the top of the actuating frame. A round rod is rotatably connected to one side of the mounting plate, and an actuating plate is fixedly connected to the surface of the round rod. The center point of the actuating plate and the center point of the arc-shaped groove are located on the same vertical plane. This facilitates the feeding that has entered the arc-shaped groove to be pushed out in the opposite direction of the movement of the actuating frame and fall back onto the conveyor belt. It also helps to disperse the feeding and change its position, thereby ensuring that the feeding on the conveyor belt is dried evenly.

[0009] Preferably, the driving assembly includes a first motor fixedly connected to the other side of the drying chamber. The output shaft of the first motor passes through the drying chamber and is fixedly connected to a reciprocating lead screw. A moving ring is provided on the surface of the reciprocating lead screw. The top end of the mounting plate is fixedly connected to the lower end of the moving ring. One end of the round rod passes through the mounting plate and is fixedly connected to a gear. A rack is fixedly connected to the inner wall of the drying chamber, and the gear meshes with the rack. This facilitates the simultaneous reciprocating movement of the actuating frame and the synchronous rotation of the round rod, thereby ensuring the consistency of the operation of the actuating plate and the actuating frame.

[0010] Preferably, a circular tube is fixedly connected to the inner wall of the agitator frame, and multiple air outlet pipes are connected to the lower end of the circular tube. A connecting pipe connects the circular tube to the fixed tube. Simultaneously drying the conveyor belt surface along the agitator frame's movement path allows the feed to contact the dried conveyor belt surface when it falls back down after being agitated, thereby improving the drying efficiency of the feed.

[0011] Preferably, the bottom of the air outlet duct is at a higher horizontal level than the bottom of the toggle frame, and the opening at the other end of the air outlet duct is funnel-shaped. This increases the diffusion area of ​​the air blown out by the air outlet duct.

[0012] Preferably, the vertical cross-section of the agitator is an isosceles triangle, and the bottom end of the agitator is in contact with the inner wall of the arc-shaped groove. This ensures the agitator effectively moves the feed within the arc-shaped groove.

[0013] Preferably, the inner wall of the drying chamber is rotatably connected to multiple evenly distributed rotating rods, the surfaces of which are in contact with the surface of the conveyor belt. This ensures the stability of the conveyor belt when the actuating frame moves in contact with the conveyor belt surface.

[0014] The beneficial effects of this utility model are:

[0015] The aforementioned drying mechanism uses low-temperature cold air blown from the outlets of multiple exhaust pipes to dry the feed above the conveyor belt. Simultaneously, under the action of the drive component, the mounting plate drives the actuating frame, round rod, and actuating plate to reciprocate continuously. During the movement of the actuating frame, the feed on the conveyor belt enters the arc-shaped groove under the action of its inclined surface. When the feed enters the arc-shaped groove, it facilitates a change in position. During the synchronous rotation of the actuating plate, it helps to push the feed that has entered the arc-shaped groove out in the opposite direction of the movement of the actuating frame and fall back onto the conveyor belt. This helps to continuously disperse the feed and change its position during the drying process, thereby ensuring that the feed on the conveyor belt is dried evenly.

[0016] While drying the feed on the conveyor belt, the connecting pipe allows the air in the fixed pipe to enter the circular pipe synchronously. With the help of multiple air outlet pipes, the moving frame moves while the surface of the conveyor belt along the moving frame's path is dried simultaneously. This ensures that the feed comes into contact with the dry conveyor belt surface when it falls back down after being moved, thereby improving the drying efficiency of the feed.

Detailed Implementation

[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] In practical implementation: such as Figure 1-5 As shown, a fish, shrimp and crab feed dryer includes: a drying chamber 100, with two circular rollers 200 rotatably connected to the inner wall of the drying chamber 100, and a conveyor belt 300 drivingly connected between the two circular rollers 200; a drying mechanism 400, which includes a drive assembly 460 and a cold air fan 410 installed on one side of the drying chamber 100; a fixed pipe 420 fixedly connected to the inner wall of the drying chamber 100, with multiple evenly distributed exhaust pipes 421 communicating with the surface of the fixed pipe 420; one end of the fixed pipe 420 communicating with the air outlet of the cold air fan 410; a sliding actuating frame 430 slidably connected to the inner wall of the drying chamber 100, with the bottom end of the actuating frame 430 abutting the surface of the conveyor belt 300; the two sides of the actuating frame 430 forming an angle with the vertical plane; and an arc-shaped groove 431 opened at the top of the actuating frame 430.

[0025] In this embodiment, a feeding frame is fixedly connected to one side of the top of the drying box 100, and the bottom end of the feeding frame extends into the drying box 100. A first guide plate is fixedly connected to one side of the inner wall of the drying box 100. The first guide plate is inclined. The feeding frame is located between the exhaust pipe 421 and the first guide plate, so the exhaust pipe 421 does not affect the feed addition operation. A second motor is fixedly connected to the front end of the drying box 100. The output shaft of the second motor is fixedly connected to one end of one of the rollers 200. When feed is added through the feeding frame, the controller starts the second motor to drive one of the rollers 200 to rotate, thereby driving the conveyor belt 300 to drive and the other roller 200 to rotate, dispersing the feed on the conveyor belt 300. The surface of the conveyor belt 300 is provided with through holes distributed in a rectangular array to facilitate the flow of air through the conveyor belt 300. An air outlet is provided at the lower end of the surface of the drying box 100 to ensure air flow during the drying operation.

[0026] It should be noted that, in order to avoid damaging the probiotics and vitamins added to the fish, shrimp and crab feed, the air cooler 410 in this solution uses low-temperature cold air at 5-15℃ to achieve gentle dehydration and complete the drying operation.

[0027] like Figure 4 and Figure 5 As shown, the drying mechanism 400 also includes a mounting plate 440 fixedly connected to one side of the top of the actuating frame 430. A round rod 450 is rotatably connected to one side of the mounting plate 440, and an actuating plate 451 is fixedly connected to the surface of the round rod 450. The center point of the actuating plate 451 and the center point of the arc groove 431 are located on the same vertical plane. The vertical cross-section of the actuating plate 451 is an isosceles triangle, and the bottom end of the actuating plate 451 is in contact with the inner wall of the arc groove 431.

[0028] In this embodiment, the center of the arc groove 431 coincides with the center of the round rod 450. When the round rod 450 drives the actuating plate 451 to rotate, the rotation path of the actuating plate 451 coincides with the arc surface of the inner wall of the arc groove 431. Therefore, when the actuating plate 451 rotates into the arc groove 431, the other end of the actuating plate 451 is always in contact with the inner wall of the arc groove 431.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the drive assembly 460 includes a first motor 461 fixedly connected to the other side of the drying chamber 100. The output shaft of the first motor 461 passes through the drying chamber 100 and is fixedly connected to a reciprocating screw 462. A moving ring 463 is provided on the surface of the reciprocating screw 462. The top end of the mounting plate 440 is fixedly connected to the lower end of the surface of the moving ring 463. One end of the round rod 450 passes through the mounting plate 440 and is fixedly connected to a gear 464. A rack 465 is fixedly connected to the inner wall of the drying chamber 100. The gear 464 and the rack 465 are meshed together.

[0030] In this embodiment, a limiting block is fixedly connected to the other side of the mounting plate 440. The surface of the limiting block is slidably connected to the inner wall of the drying oven 100 to limit the movement of the mounting plate 440. When the first motor 461 is started by the controller, the output shaft of the first motor 461 will drive the reciprocating screw 462 to rotate, thereby driving the moving ring 463 to move the mounting plate 440 reciprocally in the horizontal direction. (See reference...) Figure 3 When the drive mounting plate 440 moves the round rod 450 and the actuating frame 430 away from the first motor 461, the feed on the conveyor belt 300 will enter the arc-shaped groove 431 under the action of its inclined surface during the movement of the actuating frame 430. At the same time, under the action of the rack 465 and the gear 464, the round rod 450 will drive the actuating plate 451 to continue to rotate clockwise. During the rotation of the actuating plate 451, the feed that has entered the arc-shaped groove 431 will be pushed out in the opposite direction of the movement of the actuating frame 430. When the pushed-out feed falls onto the conveyor belt 300, its position changes. When the drive mounting plate 440 moves the round rod 450 and the actuating frame 430 closer to the first motor 461, it will drive the actuating plate 451 to rotate counterclockwise. The operating principle is the same as described above.

[0031] like Figure 4 and Figure 5 As shown, a circular tube 470 is fixedly connected to the inner wall of the toggle frame 430. Multiple air outlet tubes 471 are connected to the lower end of the surface of the circular tube 470. A connecting tube 472 connects the circular tube 470 and the fixed tube 420. The horizontal height of the bottom end of the air outlet tube 471 is higher than the horizontal height of the bottom end of the toggle frame 430, and the opening at the other end of the air outlet tube 471 is funnel-shaped.

[0032] In this embodiment, the connecting pipe 472 is a rubber component, and the middle part of the connecting pipe 472 is set as a flexible hose. When the bottom end of the actuating frame 430 contacts the surface of the conveyor belt 300, the bottom end of the air outlet pipe 471 is away from the surface of the conveyor belt 300.

[0033] like Figure 2 As shown, the inner wall of the drying chamber 100 is rotatably connected to a plurality of evenly distributed rotating rods 480, and the surface of the rotating rods 480 is in contact with the surface of the conveyor belt 300.

[0034] In this embodiment, multiple rotating rods 480 are disposed on the inner side of the conveyor belt 300, and the multiple rotating rods 480 support the conveyor belt 300 to ensure the stability of the toggle frame 430 when it moves in contact with the surface of the conveyor belt 300.

[0035] In use, feed pellets are poured onto the conveyor belt 300 through the feed box. Simultaneously, the conveyor belt 300 is driven to disperse the feed evenly across it. Once the feed pellets are evenly distributed on the conveyor belt 300, the conveyor belt stops, and the controller starts the cooling fan 410 to introduce low-temperature air into the fixed pipe 420. This air then enters multiple exhaust pipes 421 and is blown out from multiple outlets on the exhaust pipes 421 to dry the feed pellets on the conveyor belt 300. Simultaneously, the controller starts the first motor 461 in the drive assembly 460, which drives the reciprocating screw 462 to rotate. This causes the moving ring 463 to reciprocate horizontally via the mounting plate 440, moving the actuating frame 430, the round rod 450, and the actuating plate 451. During its movement, the actuating frame 430 pushes the feed particles on the conveyor belt 300. Under the action of its inclined surface, the feed on the conveyor belt 300 enters the arc groove 431. At the same time, under the action of the rack 465 and the gear 464, the round rod 450 is driven to rotate the actuating plate 451. During the rotation of the actuating plate 451, the feed that has entered the arc groove 431 is pushed out in the opposite direction of the movement of the actuating frame 430. When the pushed-out feed falls onto the conveyor belt 300, it will be dispersed and its position will change. At the same time, the air in the fixed pipe 420 will enter the round pipe 470 through the connecting pipe 472 and be blown out from multiple air outlet pipes 471 to dry the surface of the conveyor belt 300. This way, when the feed is pushed and falls again, it will come into contact with the dry surface of the conveyor belt 300, improving the drying effect of the feed.

[0036] The reciprocating screw 462 is represented by two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. The rotation of the reciprocating screw 462 causes the side of the helical groove to push the slider placed in the helical groove to make axial reciprocating motion. Therefore, when the reciprocating screw 462 is driven to rotate, the moving ring 463 will drive the mounting plate 440 to reciprocate in the horizontal direction.

[0037] It should be noted that the air coolers, motors, etc. mentioned above are all components with relatively mature existing technologies. Specific models can be selected according to actual needs. At the same time, the air coolers and motors can be powered by built-in power supplies or mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
