Description

Technical Field

[0001] The present invention relates to the field of heat exchange equipment, and in particular to a high-pressure combined heat exchange plate and a processing technology thereof. Background Art

[0002] Urban wastewater, such as sewers, currently contains a significant amount of heat. To effectively utilize this heat, a partitioning heat exchanger is essential. However, this wastewater is primarily dirty, containing numerous impurities that can easily clog the heat exchanger. However, the internal channel spacing of currently used partitioning heat exchangers is small, making them susceptible to clogging by impurities in the wastewater, thus affecting their proper function. Summary of the Invention

[0003] The present invention addresses the problems of the prior art by developing a wide-channel, unobstructed flow heat exchange plate. Dirty water flows through the wide channel side, while clean media flows through the narrow channel side. Heat exchange between the media on both sides occurs through the heat exchange plate without clogging or mixing, thus resolving the aforementioned issues.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A high-pressure combined heat exchange plate and a processing technology thereof include a main frame, an observation window and an indicator light are provided at the outer side of the main frame, the indicator light is provided at the upper end of the main frame, an upper feeding conveyor belt and a material preparation conveyor belt are provided inside the main frame, the upper feeding conveyor belt is provided above the material preparation conveyor belt, a material lifting component is provided above the upper feeding conveyor belt, and a laser cutting component is provided directly above the material lifting component.

[0005] Preferably, the upper feeding conveyor belt includes a feeding shaft, a transverse limiting plate and a driving motor. The feeding shaft is arranged on the right side of the upper feeding conveyor belt, and the upper feeding conveyor belt is provided with a driving motor. The inner side of the upper feeding conveyor belt is provided with a transverse limiting plate.

[0006] Preferably, the material lifting component includes a hydraulic cylinder, a matching base plate, a direction correction shaft, a loading plate and a cutting groove. The hydraulic cylinder is arranged at the bottom position of the material lifting component, and a matching base plate is matched with the upper position of the hydraulic cylinder, and four horizontally arranged direction correction shafts are arranged on the matching base plate. The direction correction shaft is arranged parallel to the output end of the hydraulic cylinder, and a loading plate is matched with the output end of the hydraulic cylinder. The loading plate is arranged parallel to the matching base plate, and two symmetrically distributed cutting grooves are arranged at the center position of the loading plate.

[0007] Preferably, the laser cutting component includes a mounting and fixing bracket, a controller, a transverse control track, a vertical control track and a laser cutting probe. The mounting and fixing bracket is arranged directly above the upper feeding conveyor belt. The mounting and fixing bracket is provided with a transverse control track and a vertical control track, and the vertical control track is provided on the transverse control track. The vertical control track is provided with a laser cutting probe, and the controller is provided on the outer side of the laser cutting probe.

[0008] Preferably, the material preparation conveyor belt is arranged parallel to and below the upper feeding conveyor belt, and the conveying spacing of the material preparation conveyor belt is adjustable.

[0009] Preferably, the method comprises the following specific steps: Step 1: A heat exchange plate is transported to the material lifting component position by the upper feeding conveyor belt, and laser cutting is performed by the laser cutting component set at the upper position to cut four symmetrical reinforcement notches in the center of the heat exchange plate.

[0010] Step 2: Use the upper feeding conveyor to transport a heat exchange plate to the position of the material lifting component. Laser cutting is performed by the laser cutting component set at the upper position to cut four rectangular notches of the same area at the four corners of the heat exchange plate for use as bending preparation.

[0011] Step 3: Bend the heat exchange plates with four corner cuts to make them into a box bottom plate style. Then stack the two cut heat exchange plates together, insert tie bars at the cut positions of the heat exchange plates, and weld the tie bars to the box bottom plate and the non-bent heat exchange plates respectively. The box bottom plate and the non-bent heat exchange plates are welded along all sides to form a heat exchange narrow channel box. The holes on the side of the box serve as the inlet and outlet of the clean medium.

[0012] Step 4: Insert the distance plate into the completed heat exchange narrow channel box, so that the heat exchange narrow channel box and the distance plate form a mutually spaced sewage flow channel.

[0013] Compared to existing technologies, the present invention provides a high-pressure combined heat exchange plate and its processing technology, offering the following advantages: This device solves the problem of easy clogging within partition-type heat exchangers. The unobstructed flow path is free of support, allowing even the most contaminated media to flow unimpeded. The width of the unobstructed flow path can be arbitrarily increased or decreased based on the contamination level of the media. Tie rods are incorporated into the narrow channel box to withstand high pressures. The gaps and number of tie rods within the narrow channel box can be adjusted to suit the media and process requirements. This enables heat exchange with media of varying complex compositions, effectively improving the device's adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
