Aquatic feed drying and dehumidifying device

Abstract

This utility model discloses an aquatic feed drying and dehumidification device, belonging to the field of post-production drying of aquatic feed. The device includes several crushing rods, separating blocks, a filter screen, and a spiral rod. The filter screen divides the processing chamber into two areas. When aquatic feed enters the processing chamber, it first contacts the crushing rods, breaking down lumpy aquatic feed. After crushing, the aquatic feed falls onto the surface of the filter screen, where it is sorted by the sliding filter screen. Incompletely crushed aquatic feed remains above the filter screen and is thrown upwards by the sliding action of the filter screen, colliding again with the crushing rods and the aquatic feed to break it down further. The aquatic feed that has passed through the filter screen is stacked and moved by the spiral rod. During the drying process, all aquatic feed continuously moves, changing its contact area with the heating system, facilitating rapid drying. Furthermore, upon discharge, incompletely crushed aquatic feed separates from qualified aquatic feed, ensuring that the discharged aquatic feed meets size requirements and is in a dry state.

Description

Technical Field

[0001] This utility model relates to the field of feed drying, and in particular to an aquatic feed drying and dehumidification device. Background Technology

[0002] Aquatic feed is a nutritional food specifically designed for aquatic animals, aiming to meet their various nutritional needs for growth, reproduction, and health maintenance. To ensure product quality and extend shelf life, aquatic feed generally needs to be dried using drying equipment after production.

[0003] The reference patent title is: A drying equipment for aquatic feed processing (Patent Publication No.: CN222317529U). A drying cylinder and a warm air fan are fixedly connected to the top of the base. A valve is fixedly connected to the bottom of the drying cylinder. An external blowing mechanism is fitted on the outside of the drying cylinder and fixedly connected to the top of the base. The external blowing mechanism is used to blow hot air onto the drying cylinder from the outside. The top of the base has multiple exhaust holes in a ring shape for the gas blown by the external blowing mechanism to be discharged. At the same time, a rotating connecting pipe is set inside the base. The hot air generated by the warm air fan is introduced into the connecting pipe and the drying cylinder to achieve synchronous heating inside and outside. At the same time, the connecting pipe breaks up the lumps of aquatic feed to ensure the drying effect.

[0004] However, the following problems exist when implementing the above technical solutions: the above devices only complete the crushing by striking the connecting pipe. After the aquatic feed is fed into the hopper, the contact time with the connecting pipe is limited, and the impact received is limited, making it difficult to ensure that the block aquatic feed is crushed into powder and dried. Moreover, the fallen aquatic feed is easy to accumulate. At this time, the block aquatic feed is more difficult to move under the action of the connecting pipe than the powdered aquatic feed, so as to be crushed or dried again.

[0005] Therefore, this utility model proposes an aquatic feed drying and dehumidification device. Utility Model Content

[0006] This invention provides an aquatic feed drying and dehumidification device, which can solve the problem that existing aquatic feed drying equipment cannot guarantee that block aquatic feed is broken into appropriate sizes and completely dried.

[0007] A drying and dehumidifying device for aquatic feed includes a drying tank, the drying tank having a processing chamber inside, and a drying mechanism being installed inside the processing chamber. The drying mechanism includes:

[0008] A stirring assembly, rotatably disposed inside the processing chamber, comprises:

[0009] A partition block is fixedly installed inside the processing cavity. The partition block has a fan-shaped cross-section. Several crushing rods and a spiral rod are rotatably connected inside the partition block. The crushing rods are arranged in a ring around the center of the processing cavity. The center of the spiral rod is on the same vertical line as the center of the partition block. The distance between the crushing rod and the bottom of the processing cavity is greater than the distance between the spiral rod and the bottom of the processing cavity.

Detailed Implementation

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0029] like Figures 1 to 5 As shown in the figure, an embodiment of this utility model provides an aquatic feed drying and dehumidification device, including a drying tank 1. The drying tank 1 has a processing chamber inside, and a drying mechanism is provided inside the processing chamber. The drying mechanism includes:

[0030] A stirring assembly, rotatably disposed inside the processing chamber, comprises:

[0031] A partition block 2 is fixedly installed inside the processing cavity. The partition block 2 has a fan-shaped cross-section. Several crushing rods 3 and a spiral rod 4 are rotatably connected inside the partition block 2. The crushing rods 3 are arranged in a ring around the center of the processing cavity. The center of the spiral rod 4 is located on the same vertical line as the center of the partition block 2. The distance between the crushing rod 3 and the bottom of the processing cavity is greater than the distance between the spiral rod 4 and the bottom of the processing cavity. A transmission assembly is provided between the crushing rods 3 and the spiral rod 4. A filter screen 5 is slidably installed between the partition block 2 and the processing cavity.

[0032] A drying assembly is fixedly disposed between the drying tank 1 and the processing chamber;

[0033] In summary, the aquatic feed drying and dehumidification device provided by this utility model includes several crushing rods 3, separating blocks 2, filter screens 5, and spiral rods 4. The processing chamber is divided into two areas by the filter screens 5. When the aquatic feed enters the processing chamber, it first contacts the crushing rods 3 to crush the blocky aquatic feed. After crushing, the aquatic feed falls onto the surface of the filter screens 5 and is classified by the sliding filter screens 5. The incompletely crushed aquatic feed remains above the filter screens 5 and continues to contact the crushing rods 3 to change size. The aquatic feed is stacked through the filter screens 5, but it will move under the action of the spiral rods 4. Thus, all the aquatic feed will move continuously during the drying process, which is convenient for rapid drying. When discharged, the incompletely crushed aquatic feed is separated from the qualified aquatic feed, and can be collected and crushed in batches to ensure that the size of the discharged aquatic feed meets the requirements and is in a dry state.

[0034] In some specific implementations, the transmission assembly includes transmission gears 6 or drive wheels 8 fixedly disposed on the surfaces of a plurality of crushing rods 3, and drive gears 7 fixedly connected to the surface of the spiral rod 4, wherein the transmission gears 6 and drive gears 7 mesh; only a single transmission gear 6 or a single drive wheel 8 exists on the surface of a single crushing rod 3, and the drive wheel 8 and the transmission gear 6 are not fixed to the surface of a single crushing rod 3 at the same time. Through the meshing of the transmission gear and the drive gear 7, the rotation of the crushing rod 3 can drive the spiral rod 4 to rotate, thereby enabling the simultaneous crushing and tumbling movement of aquatic feed;

[0035] In a further embodiment, a synchronous pulley 9 is fixedly connected to the surface of the spiral rod 4, and a synchronous belt 10 is connected between the synchronous pulley 9 and the drive wheel 8; the synchronous pulley 9, the drive wheel 8 and the synchronous belt 10 can drive the spiral rod 4 to rotate part of the crushing rod 3, at which time the rotation direction of this part of the crushing rod 3 is opposite to that of the remaining crushing rod 3, so as to quickly strike the aquatic feed between the crushing rods 3;

[0036] In a further embodiment, a motor is fixedly connected to the surface of the drying tank 1, and the end of the motor output shaft is fixedly connected to the crushing rod 3. The rotation speed and rotation direction of the crushing rod 3 and the screw rod 4 can be directly controlled by the motor.

[0037] In some specific embodiments, the drying assembly includes a warm air blower 11 fixedly mounted on the surface of the drying tank 1. A drying trough 12 is formed inside the drying tank 1, and the air outlet of the warm air blower 11 is located inside the drying trough 12. The drying tank 1 has several air inlet slots 13 and several air outlet slots 14. The air inlet slots 13 connect the processing chamber and the drying trough 12. The distance between the air inlet slot 13 and the screw rod 4 is less than the distance between the air inlet slot 13 and the crushing rod 3. The distance between the air outlet slot 14 and the screw rod 4 is greater than the distance between the air outlet slot 14 and the crushing rod 3. A guide block is fixedly connected and is located above the air inlet slot 13; a one-way valve (not shown in the figure) is fixedly connected inside both the air inlet slot 13 and the air outlet slot 14; through the cooperation of the drying slot 12 and the warm air blower 11 inside the drying tank 1, the processing chamber can be maintained at a certain temperature to dry the aquatic feed. The air inlet slot 13 is set between the drying slot 12 and the processing chamber, so that the warm air can enter the processing chamber and directly contact the turned aquatic feed. Finally, it is discharged through the upper air outlet slot 14, so that the surface of the incompletely crushed aquatic feed is dried, which is convenient for subsequent rapid crushing.

[0038] In some specific implementations, a protruding rod 15 is fixedly connected to the surface of the filter screen 5, and a sliding groove is provided inside the drying tank 1. The sliding groove is adapted to the protruding rod 15, and a sliding spring 16 is fixedly connected between the protruding rod 15 and the sliding groove. The existence of the sliding groove can limit the sliding distance of the filter screen 5, and the sliding spring 16 can be provided so that the filter screen 5 can be quickly reset.

[0039] In a further embodiment, a sealing rod 17 is fixedly connected to the surface of the protruding rod 15, and a movable groove is provided inside the drying tank 1. The movable groove is adapted to the sealing rod 17, and the length of the sealing rod 17 is greater than the length of the sliding groove. The sealing rod 17 can ensure that when the filter screen 5 slides, the surface of the processing chamber will not have an excessively deep groove, thus preventing aquatic feed from entering and affecting the transmission.

[0040] In some specific implementations, the transmission gear 6 is fixedly connected to a drive rod 18 on the side away from the crushing rod 3, and a drive block 19 is slidably connected inside the partition block 2. The drive block 19 slides with the filter screen 5, and a moving shaft 20 is slidably connected to the surface of the filter screen 5. A vertical groove 21 is formed on the surface of the drive block 19, and an oblique groove 22 is formed on the surface of the partition block 2. The moving shaft 20 is adapted to the vertical groove 21 and the oblique groove 22. The rotation of the transmission gear 6 can cause the drive block 19 to slide back and forth. Under the action of the oblique groove 22, the moving shaft 20 will move back and forth on different horizontal planes, thereby realizing the back and forth sliding of the filter screen 5.

[0041] In a further embodiment, a drive column 23 is fixedly connected to the surface of the drive rod 18, and a horizontal groove 24 is formed on the surface of the drive block 19. The length of the horizontal groove 24 is equal to twice the length of the drive rod 18, and the horizontal groove 24 and the drive column 23 are adapted to each other. The rotation of the drive rod 18 can be converted into the reciprocating movement of the drive block 19 through the horizontal groove 24 and the drive column 23.

[0042] The working principle of this utility model:

[0043] When drying aquatic feed, first start the warm air blower 11 and the motor, then pour the aquatic feed into the processing chamber. The motor starts and drives the crushing rod 3 to rotate. The rotation of the crushing rod 3 causes the spiral rod 4 and part of the crushing rod 3 to rotate through the transmission gear 6 and the drive gear 7. At the same time, the rotation of the transmission gear 6 causes the drive rod 18 to rotate, and the drive block 19 to slide back and forth. Then, through the inclined groove 22, the filter screen 5 is caused to slide back and forth in the vertical direction. The aquatic feed first comes into contact with the crushing rod 3, is crushed and falls onto the surface of the filter screen 5. The vibration of the filter screen 5 causes the aquatic feed that meets the specifications to fall off. The warm air blower 11 causes the drying tank 12 to be filled with warm air. At the same time, the warm air enters the processing chamber through the air inlet groove 13 and is discharged through the air outlet groove 14, drying the aquatic feed inside the processing chamber.

[0044] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
