Description

Technical Field

[0001] This utility model relates to the technical field of grain pellet drying equipment, specifically a precision temperature-controlled dryer with a timing function. Background Technology

[0002] Grain dryers are essential equipment in the post-harvest processing of agriculture, used to reduce the moisture content of grains and improve their storage and processing quality. Grain dryers play a key role in modern agricultural production, not only effectively reducing grain loss but also significantly improving the grain's storability and processing quality. A grain dryer is a device that uses heating and ventilation technology to evaporate the moisture in grains, thereby reducing their moisture content. It not only solves the problem of grains being difficult to dry due to rain during the harvest season but also processes large quantities of grain in a short time, improving drying efficiency.

[0003] Currently, when using grain dryers, the corresponding amount of grain particles are directly put into the dryer for drying. After each batch is processed, the next batch of grain particles is replaced to form a continuous working mode. Although this method can meet the drying needs, it also has the disadvantage of low drying efficiency and reduced actual processing efficiency because the grain is dried directly and needs to go through a heating process to dehydrate.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a precision temperature-controlled dryer with a timing function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a precision temperature-controlled dryer with a timing function, comprising: a cabinet;

[0007] The top surface of the chamber has inlets on both sides, and a sealing door is installed on the top surface of each inlet. An electrical control box is installed on the inner wall of each inlet, and the electrical control box is electrically connected to an operation panel located on the front surface of the chamber. The operation panel is used to time and control the temperature of the preheating unit. A placement mechanism is installed below the inlet, and a preheating mechanism is installed inside the placement mechanism. The opposite surfaces of the preheating mechanism are connected to a support mechanism. The preheating mechanism is electrically connected to the electrical control box. A drive mechanism is installed above the support mechanism and connected to it. The electrical control box, placement mechanism, drive mechanism, support mechanism, and preheating mechanism together form a preheating unit. The bottom surface of the chamber is connected to a drying chamber, and a hot air blower is installed on the left side of the drying chamber.

[0008] In one embodiment, the placement mechanism comprises a placement box, an air inlet, a mounting rod, a slot, a baffle, and an electric push rod. The top surface of the placement box is open, and there is a gap between the top surface of the placement box and the inlet. The outer side of the placement box is connected to the inner wall of the box body through the mounting rod. Air inlets are provided on all four sides of the placement box. A slot is provided at the bottom of the placement box, and a baffle is slidably connected to the slot. An electric push rod is installed at the rear end of the baffle, and the electric push rod is installed and connected to the inner wall of the box body.

[0009] In one embodiment, the support mechanism consists of a support plate, fixed seats, push rods, and toothed grooves. The support plate is installed and connected to the inner wall of the box. Fixed seats are installed at intervals on the top surface of the support plate. Through holes are opened inside the fixed seats, and push rods are installed in the through holes. Toothed grooves are opened on the top surface of the push rods located between the fixed seats. The two sides of the push rods are respectively bolted to the preheating mechanism.

[0010] In one embodiment, the drive mechanism comprises a mounting frame, a motor, a rotating disk, a moving rod, a moving plate, a connecting groove, drive teeth, a base plate, and a positioning shaft. The mounting frame sits on the top surface of the support plate and is an overall cantilever structure. A motor is installed at its right extended end, and the output end of the motor is connected to the rotating disk. A moving rod is eccentrically installed on the other side of the rotating disk, and the outer circumferential surface of the moving rod is located inside the connecting groove of the moving plate. The lower part of the moving plate is an arc-shaped structure, and drive teeth that mesh with the tooth groove are installed on the bottom surface of the arc. The middle part of the moving plate is rotatably connected to the positioning shaft, and the positioning shaft is installed through the base plate.

[0011] In one embodiment, the preheating mechanism comprises a fixed plate, a positioning rod, a connecting wire, a protective tube, and a heating plate. The fixed plate is installed and connected to a push rod. The other side of the fixed plate is installed and connected to the protective tube via the positioning rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The electric control box is started through the manual operation panel, and the heating plate is adjusted at a time. When the push rod moves, the heating plate moves synchronously in the grain. The offset and tilted heating plate helps to change the orientation of the grain. The heating plate and the hot air below work together to help the grain effectively heat up before drying, accelerate the subsequent drying process, and improve the overall drying efficiency. At the same time, the used hot air is used for auxiliary preheating, which helps to save energy consumption.

[0014] 2. The motor drives the rotating disk to rotate, causing the moving rod to rotate synchronously under the limit of the connecting groove. Since the outer circumference of the moving rod abuts against the inner wall of the connecting groove, the rotation of the moving rod drives the moving plate to move back and forth. The driving teeth on the bottom surface of the moving plate, in the meshing state of the tooth groove, drive the push rod to move back and forth synchronously, so that the preheating mechanism moves back and forth in the placement box to preheat the grain particles in the placement box. The reciprocating movement helps to improve the uniformity of the heating plate movement and preheating. Attached Figure Description

[0023] like Figures 1-2 As shown, the top surface of the box 1 has inlets 11 on both sides, and a sealing door is installed on the top surface of each inlet 11. An electrical control box 3 is installed on the inner wall of each inlet 11. The electrical control box 3 is electrically connected to the operation screen 31 located on the front surface of the box 1. The operation screen 31 is used to time and adjust the temperature of the preheating unit. A placement mechanism 4 is installed below the inlet 11.

The opposite surfaces of the preheating mechanism 7 are connected to the support mechanism 6. The preheating mechanism 7 is electrically connected to the electrical control box 3. A drive mechanism 5 is installed above the support mechanism 6 and connected to it. The electrical control box 3, placement mechanism 4, drive mechanism 5, support mechanism 6, and preheating mechanism 7 together form a preheating unit. The bottom surface of the box 1 is connected to the drying box 2. A hot air blower 21 is installed on the left side of the drying box 2.

[0024] Preferably, in one embodiment, such as Figures 2-3 As shown, the placement mechanism 4 consists of a placement box 41, an air inlet 42, a mounting rod 43, a slot 44, a baffle 45, and an electric push rod 46. The top surface of the placement box 41 is open, and there is a gap between the top surface of the placement box 41 and the feed inlet 11. The outer side of the placement box 41 is connected to the inner wall of the box body 1 through the mounting rod 43. Air inlets 42 are provided on all four sides of the placement box 41. A slot 44 is provided on the bottom of the placement box 41, and a slidingly connected device is installed inside the slot 44. A baffle 45 is provided, and an electric push rod 46 is installed at the rear end of the baffle 45. The electric push rod 46 is installed and connected to the inner wall of the box 1. During operation, the hot air is supplied to the inside of the drying box 2 by starting the hot air fan 21. After drying, the hot air enters the inside of the placement box 41 through the air inlet 42 to provide auxiliary hot air for preheating. After the grain particles inside the placement box 41 are preheated, the electric push rod 46 drives the baffle 45 to move linearly under the limit of the slot 44. After the grain particles lose support, they fall into the drying box 2 for drying.

[0025] Preferably, in one embodiment, such as Figures 2-4As shown, the support mechanism 6 is composed of a support plate 61, a fixed seat 62, a push rod 63, and a toothed groove 64. The support plate 61 is installed and connected to the inner wall of the housing 1. Fixed seats 62 are installed at intervals on the top surface of the support plate 61. The fixed seat 62 has a through hole, and the push rod 63 is installed in the through hole. The top surface of the push rod 63 between the fixed seats 62 has a toothed groove 64. The two sides of the push rod 63 are respectively bolted to the preheating mechanism 7.

[0026] Preferably, in one embodiment, such as Figures 3-4 As shown, the drive mechanism 5 consists of a mounting frame 51, a motor 52, a rotating disk 53, a moving rod 54, a moving plate 55, a connecting groove 56, a drive gear 57, a base plate 58, and a positioning shaft 59. The mounting frame 51 sits on the top surface of the support plate 61. The mounting frame 51 is a cantilever structure. The motor 52 is installed at its right extended end. The output end of the motor 52 is connected to the rotating disk 53. The moving rod 54 is eccentrically installed on the other side of the rotating disk 53. The outer circumference of the moving rod 54 is located inside the connecting groove 56 of the moving plate 55. The lower part of the moving plate 55 is an arc-shaped structure, and the bottom surface of the arc is equipped with a tooth groove 64. The driving teeth 57 engage, and the middle part of the moving plate 55 is rotatably connected to the positioning shaft 59. The positioning shaft 59 is installed through the base plate 58. During operation, the rotating disk 53 is driven to rotate by the rotation of the motor 52, so that the moving rod 54 rotates synchronously under the limit of the connecting groove 56. Since the outer peripheral surface of the moving rod 54 abuts against the inner wall of the connecting groove 56, the rotation of the moving rod 54 drives the moving plate 55 to move back and forth left and right. The driving teeth 57 on the bottom surface of the moving plate 55 drive the push rod 63 to move back and forth left and right synchronously in the meshing state of the tooth groove 64, so that the preheating mechanism 7 moves back and forth in the placement box 41 to preheat the grain particles in the placement box 41.

[0027] Preferably, in one embodiment, such as Figure 2 , Figure 5As shown, the preheating mechanism 7 consists of a fixed plate 71, a positioning rod 72, a connecting wire 73, a protective tube 74, and a heating plate 75. The fixed plate 71 is installed and connected to the push rod 63. The other side of the fixed plate 71 is installed and connected to the protective tube 74 via the positioning rod 72. The connecting wire 73 is installed inside the protective tube 74. The top of the connecting wire 73 is electrically connected to the electrical control box 3, and the bottom is electrically connected to the heating plate 75. The heating plate 75 is generally vertically arranged, and the heating plate 75 is in an offset tilted shape in the vertical state. The positioning rod 72 and the connecting wire 73 are... 3. Multiple protective tubes 74 and heating plates 75 are arranged at intervals. During operation, the electric control box 3 is started by manually controlling the operation panel 31, and the heating plate 75 is timed and temperature adjusted. When the push rod 63 moves, it simultaneously moves the heating plate 75 in the grain. The offset and tilted heating plate 75 helps to change the orientation of the grain. The heating plate 75 and the hot air below work together to help the grain effectively heat up before drying, accelerate the subsequent drying process, and improve the overall drying efficiency. At the same time, the used hot air is used for auxiliary preheating, which helps to save energy consumption.

[0028] Working principle:

[0029] During operation, the hot air blower 21 supplies hot air to the inside of the drying chamber 2. After drying, the hot air enters the placement chamber 41 through the air inlet 42 to provide auxiliary hot air for preheating. After the grain particles inside the placement chamber 41 are preheated, the electric push rod 46 drives the baffle 45 to move linearly under the limit of the slot 44. After the grain particles lose their support, they fall into the drying chamber 2 for drying. The rotation of the motor 52 drives the rotating disk 53 to rotate, causing the moving rod 54 to rotate synchronously under the limit of the connecting slot 56. Since the outer circumference of the moving rod 54 abuts against the inner wall of the connecting slot 56, the rotation of the moving rod 54 drives the moving plate The moving plate 55 moves back and forth, causing the drive teeth 57 on the bottom surface of the moving plate 55 to engage with the tooth groove 64, which in turn drives the push rod 63 to move back and forth synchronously. This causes the preheating mechanism 7 to move back and forth within the placement box 41, preheating the grain particles in the placement box 41. The electric control box 3 is activated through the manual control panel 31, and the heating plate 75 is timed and temperature-adjusted. When the push rod 63 moves, it simultaneously drives the heating plate 75 to move within the grain particles. The offset and tilted heating plate 75 helps to change the orientation of the grain particles. The heating plate 75 works in conjunction with the hot air below to help the grain particles effectively heat up before drying.
