Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a finned / plate heating and transfer box. Background Technology

[0002] Currently, during the forming and processing of heat exchanger fins or plates (hereinafter referred to as workpieces), their surfaces often retain grease contaminants such as cutting oil, rust-preventive oil, and lubricant. The presence of these oil films can severely degrade the performance indicators of the workpieces. Therefore, effective cleaning treatment is necessary before proceeding to the next assembly or welding process.

[0003] Currently, common degreasing methods in the industry mainly include chemical cleaning and traditional thermal cleaning. Chemical cleaning typically uses organic solvents or alkaline cleaning agents to remove grease through soaking, spraying, etc. While effective, this method has drawbacks such as secondary pollution, high costs for subsequent wastewater treatment, significant environmental pressure, and the potential risk of corrosion to the workpiece substrate. Traditional thermal cleaning, on the other hand, often uses simple ovens or heated tunnels to evaporate grease using heat. However, these devices generally suffer from uneven heat distribution, poor temperature control accuracy, and high energy consumption. Specifically, the oven's insulation performance is poor, leading to significant heat loss; uneven heating of the workpiece may result in incomplete removal of localized oil films, while excessively high local temperatures can cause oxidation or deformation of the workpiece; furthermore, if the evaporated oil vapors are not effectively collected and treated, they pose safety hazards and pollute the workshop environment.

[0004] In addition, the existing cleaning equipment has a limited degree of automation, and the loading and unloading of workpieces mostly rely on manual labor, making it difficult to achieve efficient integration with automated production lines, which has become a bottleneck restricting the improvement of production efficiency.

[0005] Therefore, there is an urgent need in this field for a high-efficiency, environmentally friendly, energy-saving fin / plate degreasing and purification device that can be integrated into automated production lines to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a finned / plate heating and transmission box. This invention solves the technical problems of uneven heat field and low degreasing efficiency by setting up a heating system in which heating coils and forced convection devices work together, and achieves the technical effect of efficient and uniform heating and thorough removal of grease.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a finned / plate heating and transfer box for heat exchanger assembly equipment, comprising:

[0008] Frame;

[0009] Multiple heating transfer chambers are fixedly installed on the frame. Inside each heating transfer chamber is a working cavity for processing workpieces. The heating transfer chamber is a double-layer structure consisting of an inner layer and an outer layer, and heat insulation material is filled between the inner and outer layers.

[0010] A heating coil is disposed inside the working chamber for heating the working chamber;

[0011] A transmission device is provided through the working cavity of the heating and transmission box, used to carry and transport the fins or plates to be processed through the working cavity;

[0012] A forced convection device is installed inside the working chamber and works in conjunction with the heating coil to force the hot air inside the working chamber to form a forced convection, thereby achieving uniform heating.

[0013] Furthermore, the heating transmission box includes a box shell and a box cover. A locking device is installed on the box shell, and the box cover is connected to the box shell through the locking device. An inlet end and an outlet end for workpieces to enter and exit are respectively provided on the left and right sides of the box shell.

[0014] Furthermore, the transmission device includes multiple rotating shafts driven by a motor. The rotating shafts are rotatably mounted and arranged laterally between the inlet end and the outlet end. The workpiece is placed on the rotating shaft and moves from the inlet end to the outlet end as it rotates.

[0015] Furthermore, the forced convection device includes fan blades and a fan motor. The fan blades are disposed inside the heating coil, and the fan motor is fixedly connected to the bottom of the heating transmission box. The output end of the fan motor and the fan blades are mutually driven and connected.

[0016] Furthermore, a smoke exhaust pipe is connected to the top of the frame.

[0017] The advantages of this utility model are:

[0018] 1. This utility model solves the technical problems of uneven heat field and low degreasing efficiency by setting up a heating system in which heating coils and forced convection devices work together, achieving the technical effect of efficient and uniform heating and thorough removal of grease. Specifically, the heating coil set inside the heating and transmission chamber serves as the core heat source to provide stable heat energy, while the fan blades driven by the fan motor blow hot air evenly to every corner of the working chamber through forced convection, ensuring a high degree of temperature uniformity within the heating and transmission chamber. This allows the oil film on the workpiece surface to be rapidly and thoroughly evaporated at a consistent optimized temperature (200-300℃), achieving a degreasing rate of over 90%, and avoiding problems such as incomplete degreasing due to localized low temperatures or workpiece damage due to localized high temperatures.

[0019] 2. This utility model solves the technical problems of low automation and inability to operate continuously in traditional equipment by setting multiple rotating shafts that run through the housing, thus improving production efficiency and realizing automated assembly line operation. This design allows workpieces to automatically enter from the inlet end, pass through the high-temperature working chamber at a uniform speed driven by the rotating shafts, and automatically exit from the outlet end after completing the degreasing process. It eliminates manual intervention, achieves seamless connection with upstream and downstream equipment, and transforms intermittent operation into continuous production, greatly improving the production cycle and efficiency of the entire production line.

[0026] Example 1:

[0027] Figure 1 This is a schematic diagram of the overall assembly structure of this utility model. Figure 2 This is an enlarged structural schematic diagram of the present invention, as shown below. Figure 1 and Figure 2 As shown, this embodiment provides a finned / plate heating and transfer box, including a frame 1, multiple heating and transfer boxes 2, heating coils 203, a transmission device, a forced convection device, and a smoke exhaust pipe 4. The frame 1, serving as the basic support structure of the entire equipment, is welded from structural steel or steel plates, possessing sufficient rigidity and stability. Its main function is to support the heating and transfer boxes 2 above it, ensuring stable and reliable operation of the equipment. A support base is provided at the bottom of the frame 1. The heating and transfer boxes 2 in this invention are fixedly installed on the frame 1. It forms a sealed working chamber for heating and degreasing finned or plate workpieces. The heating and transfer box 2 adopts an innovative double-layer structure, including an inner outer shell 201 and an outer shell (not shown separately in the figure, but part of the double-layer structure), with high-performance thermal insulation material (such as ceramic fiber cotton) filling the space between the two layers. This design greatly reduces heat loss from the working chamber to the outside, achieving a significant heat preservation and energy-saving effect, and lowering the temperature of the outer surface of the box, ensuring operational safety.

[0028] This invention features an openable and closable cover 205 on the heating and transfer chamber 2, with a handle 2051 installed on the cover 205 for easy operation. The cover 205 and the outer shell 201 are sealed together by a locking member 2011, and a high-temperature resistant silicone sealing strip (not shown in the figure) can be provided on the contact surface between the two to ensure the sealing of the working chamber during high-temperature operation and prevent heat loss and oil and gas leakage.

[0029] This invention features an inlet end 2013 on the left side and an outlet end 2014 on the right side of the outer casing 201. Workpieces enter and exit the working chamber inside the heating and transfer chamber 2 through the inlet end 2013 and the outlet end 2014. Guide plates 2012 are installed at the inlet end 2013 and the outlet end 2014 to ensure a smooth transition for the workpieces. The heating coil 203, serving as the core heat source, is located at the bottom of the working chamber. The heating coil 203 is wound from high-performance electrothermal materials such as nickel-chromium alloy, providing a uniform and stable basic heat source for the entire working chamber. The heating coil 203 is connected to an external power supply and an intelligent temperature control system, allowing for precise adjustment and maintenance of the set temperature within a range from room temperature to 300°C.

[0030] The transmission device in this invention is used to achieve automated continuous transport of workpieces within a sealed working chamber. The core of this device consists of multiple rotating shafts 202, made of heat-resistant stainless steel (such as 304 stainless steel), which are rotatably mounted laterally between the inlet end 2013 and the outlet end 2014 of the housing via bearings. The rotating shafts 202 are driven to rotate synchronously by one or more motors (not shown in the figure) through transmission mechanisms such as sprockets, gears, or synchronous belts. The motor speed is infinitely adjustable, thereby precisely controlling the workpiece's residence time (i.e., heating time) within the chamber. The workpiece is placed directly on the parallel rotating shafts 202, and moves uniformly from the inlet end 2013 to the outlet end 2014 via the rotating shafts 202.

[0031] To ensure a highly uniform temperature field within the heating transfer chamber 2, this invention incorporates a forced convection device. This device primarily comprises fan blades 204 and a fan motor 3 driving their rotation. The fan blades 204 are located inside the heating coil 203 and are directly driven by the fan motor 3, which is installed at the bottom of the heating transfer chamber 2. When the fan blades 204 rotate, they forcibly agitate the hot air within the heating transfer chamber 2, creating a strong circulating airflow. This breaks down the temperature stratification phenomenon caused by natural convection of hot air, rapidly and evenly dispersing the heat generated by the heating coil 203 throughout the entire working chamber, ensuring consistent heating of all parts of the workpiece.

[0032] This invention features a smoke exhaust pipe 4 connected to the top of the frame 1. By installing the smoke exhaust pipe 4, the technical problems of unorganized emission of volatile oil and gas, environmental pollution, and safety hazards are solved, achieving the technical effect of environmentally friendly emissions and ensuring the safety of the workshop environment. The oil and gas generated during operation are collected centrally and guided through the smoke exhaust pipe 4 to subsequent treatment equipment (such as an externally installed activated carbon adsorption device, not shown in the figure), preventing oil and gas from spreading within the workshop, thus protecting the environment and eliminating potential fire hazards.

[0033] The working process of this utility model is as follows:

[0034] 1. The finned or plate workpiece to be processed, with grease on its surface, is conveyed to the rotating shaft 202 at the inlet end 2013 of the heating and transfer box 2 via an electric roller conveyor belt.

[0035] 2. Upon starting the equipment, the intelligent temperature control system first controls the heating coil 203 to begin heating, and simultaneously starts the fan motor 3 to drive the fan blades 204 to rotate. The forced convection device causes the temperature inside the working chamber to rise rapidly and be evenly distributed at the set process temperature (200-300℃).

[0036] 3. The motor of the transmission device starts, driving all rotating shafts 202 to rotate synchronously and slowly. Driven by the rotating shafts 202, the workpiece moves at a constant speed from the inlet end 2013 to the outlet end 2014. During this process of passing through the high-temperature working chamber at a constant speed, the grease on the surface of the workpiece is rapidly heated and volatilized in a uniform and continuous high-temperature environment, turning into oil vapor.

[0037] 4. The evaporated oil and gas are promptly drawn out by the exhaust pipe 4 above and sent to the subsequent processing system to avoid accumulation in the cavity or contamination of the workpiece.

[0038] 5. The cleaned workpieces that have undergone degreasing are sent out from the outlet end 2014. Depending on actual needs, a cooling channel (such as forced cooling using room temperature airflow) can be set up outside the outlet end 2014 to reduce the workpiece temperature to a safe range (such as below 60°C) before collection or direct entry into the next process.

[0039] Throughout the process, heating, convection, transmission, and smoke extraction work together to achieve continuous, efficient, and uniform heating and grease removal of the workpiece in a closed environment, greatly improving production efficiency and product quality.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
