Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a hot air heating system for a vibrating conveyor. Background Technology

[0002] A vibrating conveyor is a continuous conveying machine that uses a vibrator to vibrate a trough, causing the material inside to slide or be thrown in a certain direction. During the conveying process, vibrating conveyors may encounter the problem of material sticking to the trough, especially when conveying materials with high moisture content. To prevent this, the trough temperature can be increased by heating it, reducing the adhesion between the material and the trough, thus making it easier to achieve the conveying purpose. Currently, the market mainly uses electric heating tubes to heat the trough. The heating tubes are installed below the vibrating trough and heat the trough through thermal radiation. This heating method has the following drawbacks: The heating tubes operate at high temperatures for extended periods, and due to their poor thermal conductivity, they cannot actively dissipate heat, accelerating surface oxidation and shortening their lifespan. Furthermore, replacing the heating tubes is difficult, requiring machine shutdown and disassembly, affecting production continuity; if the heating tubes are integrated with the trough, they vibrate together with the trough, making them more susceptible to damage under heat. If the heating tubes are non-contact installed, due to heat conduction issues, much heat is wasted, forcing an increase in heating power to achieve the desired heating effect. Regardless of the installation method, the heating area of ​​the heating tube is not proportional to the area of ​​the tank to be heated, which can easily lead to uneven heating. In addition, the design of temperature detection points in the heated tank is also quite difficult. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a hot air heating system for vibrating conveyors. This system offers excellent heating uniformity. The air duct is welded to the vibrating trough, with the inlet and outlet located on one side of the duct. This facilitates a flexible connection between the duct and the inlet / outlet pipes via hose clamps. In this way, only the air duct assembly vibrates with the vibrating trough, while the industrial hot air blower, inlet pipe, and outlet pipe, fixed to the ground, are unaffected by vibration, thus extending the equipment's lifespan, reducing the failure rate, and improving heat transfer efficiency. Furthermore, the industrial hot air blower and inlet / outlet pipes are conveniently located beside the trough for easy disassembly and maintenance. Because the hot air blower body continuously circulates air while heating, the heating components have excellent heat dissipation, preventing high temperatures on the heating element surface and extending the heating element's lifespan. Additionally, the continuous flow of hot air within the duct of the equipment trough ensures uniform heating and high heat transfer efficiency.

[0004] The purpose of this utility model is achieved as follows:

[0005] A hot air heating system for a vibrating conveyor includes a vibrating trough, which is vibratingly supported on a frame. A duct assembly is fixedly installed at the bottom of the vibrating trough. The duct assembly includes a duct, a guide plate, an inlet module, and an outlet module. The hollow duct is welded to the bottom of the vibrating trough. The guide plate encloses the interior of the duct in an S-shaped labyrinthine channel. An inlet module and an outlet module are located on one side of the duct's width direction, respectively at the beginning and end of the S-shaped labyrinthine channel and on the same side of the vibrating trough. The inlet of the inlet module is connected to an inlet pipe via a high-temperature hose, and the outlet of the outlet module is connected to an outlet pipe via a high-temperature hose. The two ends of each high-temperature hose are secured with hose clamps. The inlet and outlet pipes are respectively connected to the hot air outlet and circulating air inlet of an industrial hot air blower.

[0006] Preferably, the air inlet module and the air outlet module have the same structure and are both welded components. The air inlet module includes an air inlet and an air collecting cavity. The vertically arranged air inlet is connected to the entrance of the S-shaped labyrinth channel in the air duct through the air collecting cavity. The air collecting cavity is located on the side of the vibration groove. The air inlet is located below the air collecting cavity and is connected to the inside of the air collecting cavity. The vertically arranged air inlet is connected to the high-temperature hose at the top of the air inlet pipe through a hose clamp.

[0007] Preferably, a stiffening plate is provided above the air collecting cavity, and the stiffening plate is welded to both the air collecting cavity and the vibration groove.

[0008] Preferably, the air inlet pipe and the air outlet pipe are supported and fixed to the ground by a support frame, and the top of the support frame is provided with a split pipe clamp, which is used to clamp and fix the air inlet pipe or the air outlet pipe.

[0009] Preferably, the width of the air duct is adapted to the width of the vibration trough, and the air duct is provided with multiple clearance cavities.

[0010] Preferably, the air duct is formed by bending an air duct plate, and the air duct plate has "7"-shaped folded edges around its perimeter. The "7"-shaped folded edges include vertical support edges and horizontal fitting edges. The vertical support edges around the perimeter form the sidewalls of the air duct, and the horizontal fitting edges are fitted to the bottom surface of the vibration trough.

[0011] Preferably, the side wall of the air duct is provided with an observation door.

[0012] The beneficial effects of this utility model are:

[0013] The air duct is welded to the vibrating tank, and the air inlet and outlet are located on one side of the air duct. This allows the air duct to be connected to the inlet and outlet pipes via hose clamps. In this way, only the air duct assembly vibrates with the vibrating tank, while the industrial hot air blower, inlet pipe, and outlet pipe fixed to the ground are not affected by the vibration, which improves the service life of the equipment, reduces the failure rate, and improves the heat transfer efficiency. At the same time, the industrial hot air blower and inlet and outlet pipes are located on the side of the tank, making disassembly and maintenance convenient.

[0014] The hot air generated by the industrial hot air blower enters the S-shaped labyrinth channel in the air duct through the air inlet pipe, transferring heat to the vibrating tank. The S-shaped labyrinth channel extends the contact between the hot air and the vibrating tank, thereby achieving the purpose of uniform heating of the vibrating tank. After exchanging heat with the vibrating tank and cooling down, the hot air returns to the industrial hot air blower through the air outlet pipe, forming a hot air circulation system. The industrial hot air blower regulates the temperature and flow rate of the hot air entering the air duct, controlling the temperature of the circulating hot air at 150-200℃ to avoid local overheating. The continuous circulation of hot air greatly improves the heat transfer efficiency. Attached Figure Description

The air duct assembly 2 includes an air duct 2.1, a guide plate 2.2, an air inlet module 2.3, and an air outlet module 2.4. The hollow air duct 2.1 is welded to the bottom of the vibrating trough 1. The guide plate 2.2 encloses the interior of the air duct 2.1 into an S-shaped labyrinth channel. The width of the air duct 2.1 is adapted to the width of the vibrating trough 1. An air inlet is provided on one side of the width direction of the air duct 2.1. Air module 2.3 and air outlet module 2.4 are respectively located at the beginning and end of the S-shaped labyrinth channel and on the same side of the vibration tank 1. The air inlet 2.3.1 of the air inlet module 2.3 is connected to the air inlet pipe 3 through a high-temperature hose 5, and the air outlet of the air outlet module 2.4 is connected to the air outlet pipe 4 through a high-temperature hose 5. The two ends of each high-temperature hose are locked with hose clamps 8. In this way, only the air duct assembly 2 vibrates with the vibration tank 1, while the industrial hot air blower 6, the air inlet pipe 3 and the air outlet pipe 4 are not affected by the vibration, resulting in a low failure rate. The air inlet pipe 3 and the air outlet pipe 4 are respectively connected to the hot air outlet and the circulating air inlet of the industrial hot air blower 6.

[0020] The air inlet module 2.3 and air outlet module 2.4 have the same structure and are both welded components. The air inlet and air outlet modules lead the air inlet and air outlet of the air duct to the side of the vibration tank 1, which facilitates the connection between the air inlet and outlet pipes and the air duct assembly, and makes disassembly and maintenance convenient. The air inlet module 2.3 includes an air inlet 2.3.1, an air collecting cavity 2.3.2, and a stiffening plate 2.3.3. The vertically arranged air inlet 2.3.1 is connected to the entrance of the S-shaped labyrinth channel in the air duct 2.1 through the air collecting cavity 2.3.2. The air inlet 2.3.1 is located below the air collecting cavity 2.3.2 and is connected to the interior of the air collecting cavity 2.3.2. The stiffening plate 2.3.3 is located above the air collecting cavity 2.3.2 and is welded to both the air collecting cavity 2.3.2 and the vibration tank 1 to strengthen the connection strength of the air duct assembly 2. Correspondingly, the air outlet module 2.4 includes an air outlet, an air collection cavity and a stiffener plate.

[0021] The air inlet pipe 3 and the air outlet pipe 4 are supported and fixed to the ground by the support frame 9. The top of the support frame 9 is provided with a split pipe clamp 10, which is used to clamp and fix the air inlet pipe 3 or the air outlet pipe 4.

[0022] The hot air generated by the industrial hot air blower 6 enters the S-shaped labyrinth channel within the air duct 2.1 through the air inlet pipe 3, transferring heat to the vibrating tank 1, thereby achieving uniform heating of the vibrating tank 1. After heat exchange and cooling with the vibrating tank 1, the hot air returns to the industrial hot air blower 6 through the air outlet pipe 4, forming a hot air circulation system. This hot air circulation system is equipped with a temperature sensor that monitors the temperature of the system in real time. The controller of the industrial hot air blower adjusts the temperature and flow rate of the hot air entering the air duct, controlling the circulating hot air temperature between 150-200℃. By precisely controlling the hot air temperature and flow rate, the industrial hot air blower avoids overheating and uneven heating common with conventional electric heating elements.

[0023] The air duct 2.1 is provided with multiple upward-facing clearance cavities 2.5, which do not affect the installation of other components on the bottom surface of the vibration tank 1. The clearance cavities 2.5 are surrounded on all four sides and welded to the vibration tank. The barriers ensure the airtightness of the air duct, and the air guide plate can be used as part of the barriers.

[0024] The air duct 2.1 is formed by bending an air duct plate. The air duct plate has "7"-shaped folded edges around its perimeter. The "7"-shaped folded edges include a vertical support edge 2.1.1 and a horizontal fitting edge 2.1.2. The vertical support edge 2.1.1 around the perimeter forms the side wall of the air duct 2.1.

[0025] The side wall of the air duct 2.1 is provided with an observation door 2.6, which facilitates personnel inspection, maintenance, and troubleshooting. The observation door must be well sealed to prevent hot air leakage from affecting heating efficiency.
