Description

Technical Field

[0001] This utility model relates to the field of surface coating technology for metallurgical parts, specifically to a heating device for surface coating of metallurgical parts. Background Technology

[0002] To improve the drying efficiency of coatings on metallurgical parts, the coated parts are usually heated.

[0003] Existing surface coating heating devices for metallurgical parts mostly consist of several heating lamps or heating rods installed in a closed heating chamber, which are then used for direct heating. Although a fan can be added to promote airflow circulation within the heating chamber, the moisture generated after the coating is heated accumulates repeatedly during circulation and gradually increases as parts pass through, making it difficult to expel and resulting in poor drying performance. Furthermore, due to the closed design of the heating chamber, heating batches of workpieces require repeated opening and closing of the chamber to meet loading and unloading needs, preventing continuous drying and severely reducing the processing efficiency of the parts. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is the lack of a dehumidification component, which prevents the water vapor generated during the heating process from being discharged, thus reducing the drying effect. The closed design of the heating box also prevents continuous drying, reducing the processing efficiency of the parts.

[0006] II. Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a heating device for surface coating of metallurgical parts, including a heating box, a plurality of heating rods are evenly distributed on both sides of the heating box, the heating box is open at both ends, a transmission component for reciprocating conveying of parts is provided inside the heating box, and dehumidification return air components are respectively connected to both sides of the heating box. The dehumidification return air components include a return air pipe connecting the top and bottom of the heating box, and a dehumidifying fan for guiding the air in the heating box to circulate and dehumidify, and a condensation dehumidification component for condensing and dehumidifying the water vapor in the air.

[0008] Furthermore, the transmission assembly includes a fixed plate connected to the top of the heating box near the open end. A motor is connected to one side of the fixed plate, and the power output end of the motor rotates through the fixed plate and is connected to a drive wheel at the end. A driven wheel is rotatably connected to the other side of the fixed plate. A high-temperature resistant conveyor belt is provided between the driven wheel and the drive wheel. Several clamping elements for clamping parts are evenly connected on the conveyor belt.

[0009] Furthermore, the condensation dehumidification component includes a water storage tank connected to the return air duct. The return air duct is connected to a condensation plate on the side of the water storage tank away from the wind direction, which can condense water vapor in the air. The condensation plate is connected to a condensation component and several through holes for air circulation.

[0010] Furthermore, a sleeve is connected to the return air duct at the water storage tank. The diameter of the sleeve is larger than the diameter of the return air duct. The water storage tank is connected to the bottom end of the sleeve and communicates with the return air duct. A guide ring plate is connected between the sleeve and the return air duct on the side near the condenser plate. A guide block extending to the water storage tank is connected to one end of the guide ring plate, and there is a gap between the guide blocks.

[0011] Furthermore, the condensation assembly includes several connecting rods that extend into return air ducts and are evenly distributed around the condensation plate. Several heat dissipation rings are connected between the ends of the connecting rods extending into the return air ducts. The diameter of the heat dissipation rings gradually increases and they are all concentrically arranged with the condensation plate.

[0012] Furthermore, a controller is connected to the heating box, and a temperature sensor is connected inside the heating box. The controller is electrically connected to the temperature sensor, heating rod, motor, and dehumidifying fan.

[0013] III. Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] The combination of an open-ended heating chamber, heating rods, and transmission components facilitates continuous heating and drying of coated parts, enabling large-scale drying and improving production efficiency. The integrated design of the heating chamber, return air duct, dehumidifier, and condenser dehumidifier facilitates airflow within the heating chamber driven by the dehumidifier. This not only promotes air circulation, allowing airflow to pass through the parts and improve heating and drying efficiency, but also directs the air within the heating chamber to the condenser dehumidifier for dehumidification, preventing excessive moisture buildup within the heating chamber that could negatively impact drying performance. Furthermore, the dehumidified hot air can be recirculated, minimizing heat loss. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combined with appendix Figure 1 and Figure 3 A heating device for surface coating of metallurgical parts includes a heating box 1. Several heating rods 2 are evenly distributed on both sides of the heating box 1. Dehumidification and return air components are connected to both sides of the heating box 1. The dehumidification and return air components include a return air pipe 3 connecting the top and bottom of the heating box 1. The return air pipe 3 is equipped with a dehumidifying fan 4 that can guide the air in the heating box 1 to circulate it, and a condensation and dehumidification component that can condense and dehumidify the water vapor in the air. The parts pass through the heating box 1 at a uniform speed under the drive of the transmission component. After the heating rods 2 are energized, they generate heat to heat and dry the coating on the parts. The drying of the coating produces water vapor. By driving the dehumidifying fan 4, the airflow in the heating box 1 is guided, thereby facilitating the removal of water vapor from the airflow and avoiding affecting the drying effect and efficiency of the parts.

[0024] To facilitate the removal of water vapor from the airflow, combined with... Figure 3 and Figure 4The condensation dehumidification assembly includes a condenser plate 12 connected to the return air duct 3. The condenser plate 12 can condense water vapor in the air. The condenser plate 12 is connected to a condensation component and several through holes 13 for air circulation. The condensation component includes several connecting rods 17 that are evenly distributed around the condenser plate 12 and extend out of the return air duct 3. Several heat dissipation rings 18 are connected between the ends of the connecting rods 17 extending out of the return air duct 3. The diameter of the heat dissipation rings 18 gradually increases and they are all concentrically arranged with the condenser plate 12. The airflow passes through the through holes 13 on the condenser plate 12. Since the condenser plate 12 guides heat to the heat dissipation rings 18 through the connecting rods 17, the heat dissipation rings 18 can increase the contact area with the external cold air, thereby facilitating the heat dissipation of the condenser plate 12 and making the temperature of the condenser plate 12 relatively low. Water vapor in the airflow comes into contact with the condenser plate 12 and condenses into water droplets.

[0025] To facilitate the collection of water vapor into the water storage tank 11, and to reduce evaporation caused by airflow, combined with the attached... Figure 4 The return air duct 3 is connected to the condenser plate 12 near the side facing the airflow direction and a water storage tank 11 is provided. The return air duct 3 is connected to the water storage tank 11 and a sleeve 14 is provided. The diameter of the sleeve 14 is larger than the diameter of the return air duct 3. The water storage tank 11 is connected to the bottom end of the sleeve 14 and communicates with the return air duct 3. A guide ring plate 15 is connected between the sleeve 14 and the return air duct 3 near the condenser plate 12. One end of the guide ring plate 15 is connected to a guide block 16 extending to the water storage tank 11. There is a gap between the guide blocks 16 and the air storage tank 11. The water droplets condensed after the airflow passes through the guide ring plate 15 and the guide blocks 16 are guided through the gap and introduced into the water storage tank 11. At the same time, the evaporation is reduced because the contact area between the airflow and the liquid surface of the water storage tank 11 is reduced.

[0026] Example 2

[0027] Based on Example 1, in order to achieve continuous heating and drying of the coating on the parts, combined with the attached... Figure 1 and Figure 2 The heating box 1 is open at both ends. The heating box 1 is equipped with a transmission assembly that can reciprocate to transport parts. The transmission assembly includes a fixed plate connected to the top of the heating box 1 near the open end. A motor 5 is connected to one side of the fixed plate. The power output end of the motor 5 rotates through the fixed plate and is connected to a drive wheel 6 at the end. A driven wheel 8 is rotatably connected to the other side of the fixed plate. A high-temperature resistant conveyor belt 9 is provided between the driven wheel 8 and the drive wheel 6. A plurality of clamping members 10 that can clamp parts are evenly connected on the conveyor belt 9.

[0028] The combination of the open-ended heating box 1, heating rod 2, and transmission assembly facilitates continuous heating and drying of coated parts, and enables the drying of large batches of parts, thereby improving production efficiency.

[0029] Combined with appendix Figure 1 The heating box 1 is equipped with a controller 7, and a temperature sensor is connected inside the heating box 1. The controller 7 is electrically connected to the temperature sensor, heating rod 2, motor 5, and dehumidifying fan 4.

[0030] The specific usage method is as follows:

[0031] First, the parts are attached to the conveyor belt 9 by the clamping member 10.

[0032] Then, by starting the motor 5, the motor 5 drives the drive wheel 6, and the drive wheel 6, together with the driven wheel 8, drives the conveyor belt 9 to move the parts through the heating box 1 at a uniform speed. Heat is generated by the heating rod 2 to heat and dry the parts.

[0033] Next, the air inside the heating chamber 1 is guided by the dehumidifying fan 4. This not only promotes air circulation and allows the airflow to pass through the parts to improve the heating and drying efficiency, but also guides the air inside the heating chamber 1 to the condensing dehumidification component for dehumidification. This prevents the heating chamber 1 from becoming too humid during the heating process, which would affect the drying effect. It also allows the dehumidified hot air to be returned, reducing heat loss.
