Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and more specifically to a feed pellet drying equipment. Background Technology

[0002] Drying feed and feed pellets is an important processing step. Its main purpose is to remove excess moisture from the pellets to extend the shelf life of the product. It also helps to maintain or improve the nutritional value of the product. For feed (such as fish bait) and animal feed pellets, good drying can ensure product quality and avoid problems such as mold caused by moisture.

[0003] Existing pellet drying equipment, as shown in application number CN202321490652.9, "A drying and dehumidifying device for bait processing", adopts a stirring drying method, but this method easily breaks up the bait pellets.

[0004] To reduce the breakage of pellets, the existing "Application No.: CN202222151948.X, A Simple Drying Device for Rapidly and Fully Maturing Pelleted Feed" uses a conveyor belt to transport the pellets and then uses a drying device to remove water.

[0005] Although this drying method offers high protection, the particles themselves contain moisture, which may cause some adhesion when they come into contact with the conveyor belt. This adhesion can even stick directly to the surface, leading to the drawback of excessive repeated drying. Furthermore, if the residual adhesion is not cleaned in time, it will solidify and become difficult to remove, potentially affecting the quality of the subsequently dried products. Utility Model Content

[0006] The purpose of this utility model is to provide a feed pellet drying device in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This utility model proposes a feed pellet drying device, including a support frame, a conveying device and a drying device fixed on the support frame, and a guide plate fixed on the support frame. The conveying device is equipped with a conveyor belt that conveys feeds from left to right, and the guide plate is located at the lower right of the conveyor belt.

[0009] One end of the guide plate is close to the conveyor belt;

[0010] It also includes a collection trough fixed to the bracket, a discharge pipe connected to the bottom of the collection trough, a cleaning device and a rinsing device fixed to the collection trough;

[0011] The collection trough is located below the conveyor belt.

The output ends of the cleaning device and the rinsing device are provided in multiple sets, and there is a set of rinsing device output ends between each two adjacent sets of cleaning device output ends.

[0012] As a preferred technical solution of this utility model, the brushing device includes multiple sets of brush rollers that are rotatably installed in the collection trough from left to right and a drive mechanism fixed on the outside of the collection trough. The output end of the drive mechanism is connected to multiple sets of brush rollers to drive them to rotate synchronously, and the brushing end of the brush roller contacts the outer periphery of the conveyor belt.

[0013] As a preferred embodiment of the present invention, the brush roller includes a roller rod and a brush layer fixed on its outer side. The roller rod is rotatably connected in the collection groove, and the front end of the roller rod extends out of the collection groove.

[0014] As a preferred technical solution of this utility model, the driving mechanism includes a gear fixed to the front end of the roller, a toothed belt meshing with the gear, and a motor fixed to the front end of the gear. The motor is fixed to the collection groove by a support plate on the outside, and the toothed belt is arranged around the external transmission of multiple sets of gears.

The multiple sets of vertical pipes are evenly distributed from left to right.

[0016] As a preferred technical solution of this utility model, it also includes an air-flushing device fixed on the collection trough. The air-flushing device is located to the left of the brushing device and the rinsing device. The output end of the air-flushing device is obliquely upward from left to right toward the bottom end of the conveyor belt, so as to blow air onto the surface of the conveyor belt to block and disperse the water and reduce the amount of water passing above the air-flushing device.

[0017] As a preferred technical solution of this utility model, the air-impact device includes an air inlet pipe that is fixedly inserted through the inner and outer sides of the collection groove and an air-gathering plate fixedly installed on the air inlet pipe. An air-flowing plate cavity is provided in the air-gathering plate, which is obliquely upward from left to right toward the bottom end of the conveyor belt and the internal space gradually decreases.

[0018] As a preferred technical solution of this utility model, the gas gathering plate is provided with multiple sets and the discharge ends of its gas outlet plate cavity are distributed sequentially from left to right.

[0019] The beneficial effects of this utility model are as follows:

[0020] When the guide plate approaches the conveyor belt from the left end, it can scrape off the particles adhering to the surface to prevent the dried particles from drying again and becoming over-dry. The outer surface of the conveyor belt is washed by the rinsing device and brushed by the brushing device. This process cleans the outer surface of the conveyor belt. Multiple rinsing and brushing processes are used to improve the cleanliness. The entire cleaning process can be completed simply by the continuous rotation of the conveyor belt. In addition, it can be dried quickly when used with the existing drying device. The overall functionality is strong. Attached Figure Description

Detailed Implementation

[0024] like Figures 1-2 As shown, this utility model proposes: a feed pellet drying device, including a support 1, a conveying device 2 and a drying device 3 fixed on the support 1, and a guide plate 4 fixed on the support 1. The conveying device 2 is provided with a conveyor belt that conveys from left to right, and the guide plate 4 is located at the lower right of the conveyor belt.

[0025] The bait pellets are placed at the top left end of the conveyor belt and conveyed to the right. After passing through the drying device 3 for dehydration, they fall to the right end and are guided out by the guide plate 4.

[0026] One end of the guide plate 4 is close to the conveyor belt; the guide plate 4 is inclined downward from left to right. When the left end of the guide plate 4 is close to the conveyor belt, it can contact and scrape off the particles adhering to the surface to prevent the dried particles from being dried again and becoming over-dried.

[0027] It also includes a collection trough 5 fixed on the bracket 1, a discharge pipe 6 connected to the bottom of the collection trough 5, a cleaning device 7 fixed on the collection trough 5, and a rinsing device 8.

[0028] The collection trough 5 is located below the conveyor belt. The output end of the cleaning device 7 contacts the bottom end of the conveyor belt to clean its surface. The output end of the rinsing device 8 faces the bottom end of the conveyor belt to rinse it with water. The output ends of the cleaning device 7 and the rinsing device 8 are provided in multiple sets, and there is a set of rinsing device 8 output ends between each two adjacent sets of cleaning device 7 output ends.

[0029] The outer surface of the conveyor belt is rinsed by the rinsing device 8 and brushed by the brushing device 7. This process cleans the outer surface of the conveyor belt. The rinsing and brushing are repeated multiple times to improve the cleanliness. During the cleaning process, the conveyor belt only needs to rotate continuously to complete the overall cleaning. At the same time, it can be dried quickly with the existing drying device 3. The overall functionality is strong.

[0030] The specific structure of the cleaning device 7 is shown below:

[0031] The cleaning device 7 includes multiple sets of brush rollers 71 that are rotatably installed in the collection trough 5 from left to right, and a drive mechanism 72 fixed on the outside of the collection trough 5. The output end of the drive mechanism 72 is connected to the multiple sets of brush rollers 71 to drive them to rotate synchronously. The brushing end of the brush rollers 71 contacts the outer periphery of the conveyor belt. The operation of the drive mechanism 72 can drive the multiple sets of brush rollers 71 to rotate, thereby cleaning the outer surface of the conveyor belt.

[0032] Specifically: the brush roller 71 includes a roller rod 711 and a brush layer 712 fixed on its outer side. The roller rod 711 is rotatably connected in the collection groove 5, and the front end of the roller rod 711 extends out of the collection groove 5. The brush layer 712 is a nylon brush layer or a polyester (PET) brush layer. The brush layer 712 can be fixed on the surface of the roller rod 711 by means of bonding or other methods. The roller rod 711 and the collection groove 5 are rotatably connected by bearings.

[0033] Specifically: the drive mechanism 72 includes a gear 721 fixed to the front end of the roller 711, a toothed belt 722 meshing with the gear 721, and a motor 723 fixed to the front end of the gear 721. The motor 723 is fixed to the collection groove 5 by a support plate on the outside. The toothed belt 722 is arranged around the gear 721 for external transmission. The motor 723 can be a servo motor.

[0034] The multiple sets of brush rollers 71 are provided with multiple sets of roller rods 711. Each set of roller rods 711 has a gear 721 fixed at its front end. At this time, there are also multiple sets of gears 721. The toothed belt 722 meshes around the multiple sets of gears 721 and is close to them. Then, the output end of the motor 723 fixes the front end of any one of the gears 721 and drives it to rotate. At this time, the multiple sets of roller rods 711 also rotate synchronously. The brush layer 712 rotates to contact the outer surface of the conveyor belt for brushing.

[0035] The specific structure of the cleaning device 7 is shown below:

[0036] The flushing device 8 includes a water inlet pipe 81 that is fixedly inserted through the inner and outer sides of the collection tank 5, a horizontal pipe 82 that is connected and fixed to the water inlet pipe 81, multiple sets of vertical pipes 83 that are connected and fixed at the top of the horizontal pipe 82, and a nozzle 84 that is fixed at the top of the vertical pipe 83. The multiple sets of vertical pipes 83 are evenly distributed from left to right.

[0037] The inlet pipe 81 is connected to an external water supply device (not shown in the figure; the water supply device can be a pumping pipe that connects the inlet pipe 81 and the water tank, and a water pump is installed between the pumping pipes). The water flows into the horizontal pipe 82, the vertical pipe 83 and the nozzle 84 in sequence, and the nozzle 84 sprays water to the outer surface of the conveyor belt for rinsing.

[0038] Each pair of adjacent brush rollers 71 is equipped with a nozzle 84, which can be rinsed after each brushing, resulting in a good cleaning effect.

[0039] Further:

[0040] It also includes an air jetting device 9 fixed on the collection trough 5. The air jetting device 9 is located to the left of the cleaning device 7 and the rinsing device 8. The output end of the air jetting device 9 is obliquely upward from left to right toward the bottom end of the conveyor belt, so as to blow air onto the surface of the conveyor belt to block and disperse the water and reduce the water passing above the air jetting device 9.

[0041] After cleaning, the conveyor belt surface is wet. The air jet device 9 blows the water to the right, which reduces the water transfer to the drying device 3 and speeds up the drying process.

[0042] The specific structure of the air-impact device 9 is shown below:

[0043] The air-impact device 9 includes an air inlet pipe 91 that is fixedly inserted through the inner and outer sides of the collection groove 5 and an air-gathering plate 92 fixedly mounted on the air inlet pipe 91. An air-flowing plate cavity is provided in the air-gathering plate 92, which is inclined upward from left to right toward the bottom end of the conveyor belt and the internal space gradually decreases.

[0044] The air inlet pipe 91 is connected to an external air supply device (not shown in the figure, which may be a fan or a vacuum pump). The air supply enters the air inlet pipe 91 and is blown to the bottom of the conveyor belt through the air outlet cavity of the air gathering plate 92.

[0045] Among them, the air-gathering plate 92 is provided with multiple sets, and the discharge ends of its air-flowing plate cavity are distributed sequentially from left to right; such as Figure 2 As shown, the multiple sets of air-gathering plates 92 are all inclined upwards from left to right, which can provide multiple sets of air-flowing plate cavities to blow air to the bottom of the conveyor belt at multiple positions, effectively dispersing and blocking moisture from passing through.

[0046] It also includes a PLC controller that connects to an external power source, and the PLC controller is electrically connected to the aforementioned electrical components to control their on / off states.

[0047] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
