Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a spiral corrugated plate heat exchanger. Background Art

[0002] A spiral corrugated plate heat exchanger, also known as a spiral heat exchanger, utilizes heat exchange plates formed into a specific corrugated shape from static metal plates. These plates are stacked and secured with clamps and bolts. Its operating principle is based on the spiral flow of the medium between the corrugated plates. This allows the hot and cold fluids to flow through the narrow, tortuous channels formed between the two plates, exchanging heat through the intermediate interlayer plates, thereby achieving heat transfer.

[0003] In existing spiral corrugated plate heat exchangers, there is a lack of load-bearing or supporting parts between two adjacent metal heat exchange plates, resulting in low overall structural strength. In addition, existing spiral corrugated plate heat exchangers lack cleaning devices for the internal fluid channels, which are easily clogged due to impurity deposition, thereby affecting the heat exchange effect.

[0006] Furthermore, the supporting longitudinal rods and the supporting transverse rods are each provided with a plurality of through holes for fluid to pass through.

[0007] Furthermore, the opening and closing assembly includes a connecting rod, the interiors of the two fixed rods are slidably connected to sliding rods, the upper parts of the two sliding rods are connected to the connecting rod, an electric push rod is installed on the top of the cylinder, and the telescopic rod of the electric push rod is fixedly connected to the connecting rod.

[0008] Furthermore, the sliding rod is provided with water openings corresponding one to one to the multiple water spraying openings on the fixed rod.

[0009] Furthermore, the two baffles are respectively provided with an inlet 1 and an outlet 1, and the cylinder is provided with an inlet 2 and an outlet 2.

[0010] Furthermore, a waste pipe is also included, wherein a plurality of waste pipes are connected to one baffle, and a valve is provided on the waste pipe.

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] See also Figure 1-Figure 4 A spiral corrugated plate heat exchanger includes a cylinder 1, with baffles 2 fixed on the front and rear sides of the cylinder 1, and supporting longitudinal rods 8 and supporting cross rods 81 arranged in a cross shape inside the cylinder 1. The supporting longitudinal rods 8 and the supporting cross rods 81 both pass through the spiral heat exchange plate 7. The supporting longitudinal rods 8 and the supporting cross rods 81 are both provided with multiple through holes for fluid to pass through. Two fixing rods 9 are provided on the top of the cylinder 1, and a water pipe joint is provided on the top of the fixing rod 9. The water pipe joint is used to connect to an external water source. A plurality of water spray outlets are provided on the fixing rod 9, and an opening and closing component for controlling the opening and closing of the water spray outlet of the fixing rod 9 is provided on the cylinder 1.

[0019] The opening and closing assembly includes a connecting rod 11, and the interior of the two fixed rods 9 is slidably connected to a sliding rod 10. The sliding rod 10 is provided with water outlets corresponding to the multiple water outlets on the fixed rod 9. The upper parts of the two sliding rods 10 are connected to the connecting rod 11, and an electric push rod 12 is installed on the top of the cylinder 1. The telescopic rod of the electric push rod 12 is fixedly connected to the connecting rod 11. When the electric push rod 12 pushes the connecting rod 11 to rise and drives the sliding rod 10 to slide to the position where the water outlet is aligned with the water outlet, a water passage can be formed.

[0020] It also includes a waste pipe 13. A plurality of waste pipes 13 are connected to the front baffle 2. The waste pipe 13 is provided with a valve 14. The valve 14 is used to control the discharge of waste.

[0021] Working principle: When in use, the cold and hot fluids enter their corresponding fluid channels through inlet 1 3 and inlet 2 4 respectively, exchange heat between the spiral heat exchange plates 7, and then flow out through outlet 1 6 and outlet 2 5 respectively. The supporting longitudinal rods 8 and supporting cross rods 81 provide stable structural support for the spiral heat exchange plates 7.

[0022] When the fluid channel needs to be cleaned, the telescopic rod of the electric push rod 12 is extended to push the connecting rod 11 up, thereby driving the sliding rod 10 to slide in the fixed rod 9. Since the water outlet on the sliding rod 10 corresponds to the water outlet on the fixed rod 9, when the sliding rod 10 slides upward to a certain position, the water outlet is aligned with the water outlet to form a passage. At this time, the external water source is connected through the water pipe joint on the fixed rod 9, and the water flows into the fixed rod 9 and is sprayed out through the water outlet, forcefully flushing impurities in the fluid channel. After cleaning is completed, the water source is turned off, and the opening of the waste pipe 13 is opened through the valve 14, so that the cleaned waste water and impurities are discharged through the waste pipe 13, restoring the heat exchanger to the best working state.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
