Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a drying mechanism with uniform heating. Background Technology

[0002] Under the suction of the fan, fresh cold air from outside is directly introduced into the dryer through the air inlet and heat exchanged with the heater to become dry hot air. Then, it exchanges heat with the feed in the drum and is discharged from the machine. Under the action of the dry hot air, the moisture in the feed gradually evaporates, thereby achieving the effect of drying and preventing feed spoilage.

[0003] A search revealed that application number CN202323101855.7 discloses a feed dryer, including a drying box and a heating box fixedly installed at the bottom of the drying box. A rotary motor is fixedly installed at the bottom of the drying box, and a U-shaped frame is fixedly installed through the output end of the rotary motor at the bottom of the drying box. A feeding tray is provided in the opening of the U-shaped frame, and plug-in mechanisms are provided on both sides of the feeding tray to facilitate the removal of the feeding tray. The feeding tray is connected to the side inside the opening of the U-shaped frame through the plug-in mechanisms. During the drying process, the feeding tray shakes left and right while rotating, causing the feed to tumble and avoiding incomplete drying.

[0004] When existing drying equipment dries feed that clumps together or is prone to clumping, it results in uneven drying of the clumped feed. At the same time, placing the heat source on one side of several layers of feed trays makes it difficult to ensure uniform heating of the entire feed tray. Utility Model Content

[0005] The purpose of this invention is to provide a drying mechanism with uniform heating to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a drying mechanism with uniform heating, comprising a main body with a discharge port on its side wall, a storage box fixedly connected to the top of the main body, a drying assembly installed inside the main body, the top of the drying assembly communicating with the bottom of the storage box, the drying assembly including a motor, a drying body, and a blower, the motor driving the drying body to rotate, the drying body including a mounting cylinder, mounting plates rotatably connected to both ends of the inner wall of the mounting cylinder, several sets of feeding cylinders, screening cylinders, and drying cylinders fixedly connected to adjacent areas of the two sets of mounting plates, and the several sets of feeding cylinders, screening cylinders, and drying cylinders are all coaxially arranged with the mounting cylinder, the feed is screened by the screening cylinder and then dried by the drying cylinder inside the screening cylinder.

[0007] As a further preferred embodiment, the mounting cylinder includes an outer cylinder body, with a feed inlet at the top and a discharge outlet at the bottom. The feed inlet is connected to the bottom of the storage box, and the discharge outlet is connected to the discharge outlet when opened.

[0008] As a further preferred embodiment, the feed cylinder includes an inner cylinder with a notch on one side. Several sets of swing rods are hinged to the inner sidewall of the inner cylinder away from the notch at intervals. The outer diameter of the inner cylinder is equal to the inner diameter of the outer cylinder.

[0009] As a further preferred embodiment, the screening cylinder includes a porous screening cylinder body, and two sets of guide plates are fixedly connected to the side wall of the porous screening cylinder body.

[0011] As a further preferred embodiment, the motor drive shaft passes through the rear end face of the main body of the device and is fixedly connected to the mounting plate, and the blower passes through another set of mounting plates and communicates with the inner cavity of the air outlet cylinder.

[0012] Through the above technical solution, the drying mechanism with uniform heating provided by this utility model has the following advantages:

[0013] This utility model features a drying assembly. A motor drives the mounting plate to rotate, causing the outer wall of the inner cylinder to rotate in contact with the inner wall of the outer cylinder. When the opening moves to connect with the feed inlet, the feed enters the inner cavity of the feed cylinder from inside the storage box. The feed is subjected to centrifugal force and impacts the side wall of the inner cylinder from side to side. At the same time, during the rotation, the sealing plate swings to break up the feed. The broken feed is then screened by a porous screening cylinder and enters the inner cavity of the screening cylinder. Air blown in by the blower is heated by heating wires and then blown into the porous screening cylinder through the air outlet to heat and dry the screened feed, improving the uniformity of heating. Meanwhile, the overflowing hot air preheats the feed inside the inner cylinder, improving the thermal energy utilization rate and accelerating the breaking up of clumps of feed.

[0014] Meanwhile, the storage bin is connected to the outer cylinder through the inlet. As the inner cylinder rotates, the opening is intermittently connected to the inlet. When the dried feed in the multi-hole screening cylinder reaches the set amount, the dried feed is discharged through the guide plate, sealing plate, and discharge port, thereby realizing continuous feeding and discharging.

[0021] 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.

[0022] The present invention will be further described in detail with reference to the accompanying drawings.

[0023] Please see Figure 1 - Figure 5 The present invention provides a uniformly heated drying mechanism, comprising a main body 1, a storage box 2, and a drying component 3.

[0024] Please see Figure 1 and Figure 2 The device body 1 has a discharge port on its front end. The storage box 2 is installed on the top of the device body 1 to store feed to be dried. The drying component 3 is installed in the inner cavity of the device body 1 and its top is connected to the storage box 2. The feed enters the drying component 3 for crushing, screening and drying. The dried feed is discharged through the discharge port.

[0025] Please see Figures 3 to 5 The drying component 3 includes a motor 31, which is installed on the rear end face of the main body 1. The output end of the motor 31 extends into the inner cavity of the main body 1 and is fixedly connected to the drying body 32. A blower 33 is installed at the front end of the drying body 32 and is installed on the front end face of the main body 1 and is connected to the outside.

[0026] Specifically, the drying body 32 includes an installation cylinder 321. The two ends of the installation cylinder 321 are fixedly connected to the inner wall of the device body 1. The two ends of the inner wall of the installation cylinder 321 are rotatably connected to the installation plates 325. Several sets of feed cylinders 322 arranged circumferentially are fixedly connected to the adjacent side of the two sets of installation plates 325. The inner side of the several sets of feed cylinders 322 is fixedly connected to the screening cylinder 323. The inner side of the screening cylinder 323 is provided with the air drying cylinder 324. The two ends of the several sets of feed cylinders 322, screening cylinders 323 and air drying cylinder 324 are fixedly connected to the installation plates 325 and are coaxially arranged with the installation cylinder 321.

[0027] Meanwhile, the installation cylinder 321 includes an outer cylinder 3212, with a feed inlet 3211 at the top of the outer cylinder 3212, which is connected to the lower end of the storage box 2. A discharge port is provided at the lower end of the outer cylinder 3212. The feeding cylinder 322 includes an inner cylinder 3221, with a notch 3222 on one side of the outer wall of the inner cylinder 3221. Several sets of swing rods 3223 are hinged at intervals on the inner side wall of the inner cylinder 3221 away from the notch 3222. The screening cylinder 323 includes a porous screening cylinder 3231, with two sets of guide plates 3232 fixedly connected at intervals on the outer wall of the porous screening cylinder 3231. A sealing plate 3233 is provided on the side of the two sets of guide plates 3232 away from the porous screening cylinder 3231 in the adjacent area. The sealing plate 3233 can slide along the axial direction of the porous screening cylinder 3231, thereby opening the channel of the guide plate 3232.

[0028] Understandably, the inner cylinder 3221 divides the adjacent areas of the outer wall of the porous screening cylinder 3231 and the inner wall of the outer cylinder 3212 into several groups of closed areas. As the inner cylinder 3221 rotates, the opening 3222 intermittently connects with the storage box 2 through the feed inlet 3211 to achieve feeding. During the rotation, the feed is subjected to centrifugal force to impact the side wall of the inner cylinder 3221, and at the same time, the swing rod 3223 subjected to centrifugal force crushes the feed, promoting the crushing of the feed and passing through the porous screening cylinder 3231 into the inner cavity of the screening cylinder 323, thus completing the crushing and screening of the feed.

[0029] It should be added that the outer wall of the inner cylinder 3221 is fitted with the inner wall of the outer cylinder 3212, and the inner side of the inner cylinder 3221 is fixedly connected to the outer wall of the porous screening cylinder 3231.

[0030] It should also be noted that the discharge port is equipped with a baffle that slides along the axis. When discharging, the sealing plate 3233 is aligned with the discharge port, and the baffle is moved to discharge the feed from the porous screening cylinder 3231.

[0031] It should be noted that the outer wall of the outer cylinder 3212 is provided with vent holes, and the diameter of the vent holes is smaller than the diameter of the feed. The porous screening cylinder 3231 is a screen, and the diameter of the screen holes matches the required feed particle size.

[0032] Furthermore, the air drying cylinder 324 includes an air outlet cylinder 3242, with several sets of heating wires 3241 installed at intervals on the inner wall of the air outlet cylinder 3242. One end of the air outlet cylinder 3242 is connected to the blower 33. Air is blown in by the blower 33 and heated into hot air by the heating wires 3241. The hot air then passes through the air outlet cylinder 3242 and enters the porous screening cylinder 3231 to heat and dry the crushed feed. The feed rotates inside the porous screening cylinder 3231 to improve the uniformity of heating. The dried feed is guided by the guide plate 3232 and then discharged to the discharge port through the open sealing plate 3233 and the discharge port, completing the discharge process.

[0033] It should be added that the outer wall of the air outlet duct 3242 is provided with air outlet holes at intervals, and the diameter of the air outlet holes is smaller than the diameter of the feed after screening.

[0034] Principle: The feed to be dried is loaded into the storage bin 2. The motor 31 drives the mounting plate 325 to rotate, thereby causing the inner cylinder 3221 to rotate against the inner wall of the outer cylinder 3212. When the notch 3222 rotates to connect with the feed inlet 3211, the feed in the storage bin 2 enters the inner cylinder 3221. As the feed inlet 3211 rotates, the feed is subjected to centrifugal force and impacts the inner wall of the inner cylinder 3221. At the same time, the swing rod 3223, also subjected to centrifugal force, swings to further agitate the feed, preventing clumping and promoting feed drying. The material passes through the porous screening cylinder 3231 for screening. The blower 33 blows air into the air outlet cylinder 3242. The air is heated by the heating wire 3241 and then blown out through the air outlet of the air outlet cylinder 3242 to heat and dry the feed in the porous screening cylinder 3231. The overflowing hot air passes through the porous screening cylinder 3231 and enters the inner cylinder 3221 to preheat the feed before screening, improve the utilization efficiency of the heat source, and at the same time accelerate the breaking up of clumps of feed in the inner cylinder 3221, further improving the uniformity and efficiency of drying.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
