Description

Technical Field

[0001] This utility model belongs to the technical field of infrared drying equipment, and in particular relates to a feeding device for an infrared static dryer. Background Technology

[0002] An infrared static dryer is a continuous drying equipment that uses infrared radiation heat energy as its core drying method. During operation, the material passes statically through the closed drying chamber via a conveyor belt and absorbs heat energy under the direct irradiation of the infrared radiation source, achieving efficient and rapid dehydration. This type of equipment is widely used in the drying of heat-sensitive materials in the food, chemical, and pharmaceutical industries. It has advantages such as fast heating speed, high thermal efficiency, and good preservation of material color. As a key front-end component of the infrared static dryer, the feeding device undertakes the core functions of material conveying, distribution, and pretreatment. Its performance directly affects the drying uniformity and energy efficiency.

[0003] Existing feeding devices still have some problems during use. For example, the high-temperature exhaust gas generated during the drying process is usually directly discharged without effective recycling, resulting in energy waste. Traditional equipment lacks a waste heat circulation system and cannot convert waste heat into pre-treatment energy. The material to be dried on the conveyor belt is prone to local accumulation due to uneven distribution. The lower layer of the accumulated material is shielded by infrared radiation, resulting in insufficient heating and residual moisture, while the upper layer may be over-dried, causing quality deterioration and increased energy consumption.

[0004] To address these issues, we provide a feeding device for an infrared static dryer. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for an infrared static dryer. By combining a preheating mechanism and a leveling mechanism, it solves the problem in existing feeding devices where the material to be dried on the conveyor belt is prone to local accumulation due to uneven distribution, resulting in insufficient heating.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a feeding device for an infrared static dryer, comprising a conveyor belt, a drying device fixedly connected to the top of the conveyor belt, a preheating mechanism provided on one side of the top of the conveyor belt, the preheating mechanism comprising a preheating box fixedly connected to the top of the conveyor belt, an air jet assembly disposed at the top of the preheating box, and a fan fixedly connected to one side of the drying device, and a leveling mechanism provided on one side of the preheating box, the leveling mechanism comprising an extension plate fixedly connected to one side of the preheating box, a hydraulic cylinder fixedly connected to the top of the extension plate, a toothed plate fixedly connected to the output end of the hydraulic cylinder, and a leveling plate fixedly connected to one side of the toothed plate.

[0008] The present invention is further configured such that the jet assembly includes a jet plate fixedly connected to the top of the preheating chamber and a nozzle communicating with the bottom of the jet plate.

[0009] The present invention is further configured such that a wind-blocking filter is fixedly connected inside the preheating box, and the wind-blocking filter is located at the bottom of the jet assembly.

[0010] The present invention is further configured such that the air inlet of the fan is connected to the drying equipment, and the air outlet of the fan is connected to a conveying pipe.

[0011] The present invention is further configured such that a dehumidification box is fixedly connected to one side of the drying equipment, an agitation component is provided inside the dehumidification box, a blocking filter screen is fixedly connected to both sides of the dehumidification box, and a desiccant is placed inside the dehumidification box.

[0012] The present invention is further configured such that a connecting pipe is connected to one side of the dehumidification box, and the agitation assembly includes a motor fixedly connected to the top of the dehumidification box and an agitation rod fixedly connected to the output end of the motor.

[0013] The present invention is further configured such that there are two toothed plates, and the two toothed plates are staggered, and the flat plate is located at the feed inlet of the preheating box.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a fan to extract high-temperature waste gas from the drying equipment and transports it to the dehumidification box through a conveying pipe. The desiccant is dynamically agitated by a stirring rod to enhance dehumidification. The drying hot air is introduced into the preheating box through a connecting pipe and sprayed downwards through nozzles. It is diffused into a uniform hot air curtain covering the material through an air-blocking filter. This process converts waste heat into preheating energy, evaporating surface moisture before the material enters the main drying zone, effectively reducing the energy consumption of the main drying process, and avoiding the problem of secondary humidification caused by moisture backflow.

[0016] 2. This utility model uses a hydraulic cylinder to drive two staggered toothed plates to press vertically down onto the surface of the conveyor belt. The sharp teeth of the toothed plates insert into the material pile to achieve forced diversion, eliminating local accumulation. The subsequent flat plate horizontally compacts the diverted material, forming a uniform thin layer of constant thickness. This action allows the material to enter the drying zone in an unobstructed state, effectively solving the "shadow effect" caused by accumulation, maximizing the penetration depth of infrared radiation, preventing local under-drying or over-drying, and improving the product qualification rate.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model is a feeding device for an infrared static dryer, including a conveyor belt 1, a drying device 2 fixedly connected to the top of the conveyor belt 1, a preheating mechanism 3 provided on one side of the top of the conveyor belt 1, the preheating mechanism 3 including a preheating box 31 fixedly connected to the top of the conveyor belt 1, an air jet assembly 32 provided at the top of the preheating box 31, and a fan 33 fixedly connected to one side of the drying device 2, and a leveling mechanism 4 provided on one side of the preheating box 31, the leveling mechanism 4 including an extension plate 41 fixedly connected to one side of the preheating box 31, a hydraulic cylinder 42 fixedly connected to the top of the extension plate 41, a toothed plate 43 fixedly connected to the output end of the hydraulic cylinder 42, and a leveling plate 44 fixedly connected to one side of the toothed plate 43.

[0028] Specifically: By setting up the preheating mechanism 3, the high-temperature exhaust heat of the drying equipment 2 is recovered and converted into preheated airflow after dehumidification treatment. The material to be dried is preheated. The fan 33 draws out the high-temperature exhaust gas in the drying equipment 2 and delivers it to the dehumidification box 7 through the conveying pipe 6. The desiccant absorbs the moisture. The dry hot air is delivered to the jet assembly 32 of the preheating box 31 through the connecting pipe 10. The nozzle 322 at the bottom of the jet plate 321 sprays dry hot air downwards. The airflow is diverted and diffused by the wind-blocking filter 5 to form a uniform hot air curtain. By setting up the leveling mechanism 4, the problem of material accumulation on the conveyor belt 1 is eliminated, ensuring that the material enters the drying zone in a thin and uniform state, and improving the penetration efficiency of infrared radiation. The hydraulic cylinder 42 drives the two staggered toothed plates 43 to move vertically. After the sharp teeth of the toothed plates 43 come into contact with the material pile, forced diversion is achieved. The leveling plate 44 on the rear side flattens the diverted and undulating material.

[0029] Example 2

[0030] Please see Figures 1-5 Based on Embodiment 1, the jet assembly 32 includes a jet plate 321 fixedly connected to the top of the preheating box 31, and a nozzle 322 connected to the bottom of the jet plate 321. An air-blocking filter 5 is fixedly connected inside the preheating box 31, located at the bottom of the jet assembly 32. The air inlet of the fan 33 is connected to the drying equipment 2, and the air outlet of the fan 33 is connected to a conveying pipe 6. A dehumidification box 7 is fixedly connected to one side of the drying equipment 2, and an agitation assembly 8 is installed inside the dehumidification box 7. Both sides of the dehumidification box 7... A filter screen 9 is fixedly connected. A desiccant is placed inside the dehumidification box 7. A connecting pipe 10 is connected to one side of the dehumidification box 7. The other end of the connecting pipe 10 is connected to the jet assembly 32. The end of the conveying pipe 6 away from the fan 33 is connected to the other side of the dehumidification box 7. The stirring assembly 8 includes a motor 81 fixedly connected to the top of the dehumidification box 7 and a stirring rod 82 fixedly connected to the output end of the motor 81. There are two toothed plates 43, and the two toothed plates 43 are staggered. The flat plate 44 is located at the feed inlet of the preheating box 31.

[0031] Specifically: the jet assembly 32 recovers the waste heat from the drying equipment 2 to the preheating box 31 for preheating the material passing through the preheating box 31. The air baffle 5 blocks and diverts the hot air ejected from the nozzle 322, preventing the hot air from directly hitting the material. The fan 33 conveys the waste heat to the dehumidification box 7 through the conveying pipe 6. The dehumidification box 7 dehumidifies the hot air recovered by the fan 33. The connecting pipe 10 conveys the dehumidified hot air to the jet assembly 32. The agitator 8 agitates the dehumidifier to improve its dehumidification effect. The staggered toothed plate 43 diverts the material on the conveyor belt 1 to prevent high material accumulation. The diverted material is leveled by the leveling plate 44. The toothed plate 43 and the leveling plate 44 prevent high material accumulation, which would affect the drying effect.

[0032] The working principle of this utility model is as follows: the hydraulic cylinder 42 drives two staggered toothed plates 43 to move vertically downward to the surface of the conveyor belt 1. The sharp teeth of the toothed plates 43 insert into the accumulated material and divide it into multiple fine streams to avoid local accumulation. The leveling plate 44 following the toothed plates 43 levels the divided material. After leveling, the material enters the preheating box 31 at a uniform speed to receive uniform preheating.

[0033] The blower 33 starts to draw high-temperature exhaust gas from inside the drying equipment 2. The exhaust gas enters the dehumidification box 7 through the conveying pipe 6. The motor 81 drives the stirring rod 82 to rotate, stirring the desiccant to enhance the moisture adsorption efficiency. The dehumidified hot air is conveyed to the jet plate 321 in the preheating box 31 through the connecting pipe 10. The nozzle 322 at the bottom of the jet plate 321 sprays dry hot air downwards. The wind-blocking filter 5 disperses the concentrated airflow into a uniform hot air curtain, covering the material on the conveyor belt 1. The material absorbs the hot air energy before entering the drying equipment 2, and part of the surface moisture evaporates.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
