Description

Technical Field

[0001] The invention relates to the technical field of plate heat exchangers, and in particular to a side plate drilling device for a plate heat exchanger. Background Art

[0002] A plate heat exchanger is a device that uses metal plates as heat exchange surfaces. It is used to exchange heat between two fluids. It is composed of multiple thin metal plates stacked together to form fluid channels between the plates. A fluid channel is formed between each pair of adjacent plates. Hot fluid and cold fluid can flow alternately. The hot fluid flows in through one channel, and the cold fluid flows in through another channel. Heat is transferred from the hot fluid to the cold fluid to complete the heat exchange. Since the fluid flow path is long and the surface of the plate increases the heat exchange area, its efficiency is relatively high. It is widely used in chemical, food, pharmaceutical, HVAC and other fields.

[0045] Specifically, the working principle of the side plate drilling device of the plate heat exchanger is as follows: when in use, after the side plate of the heat exchanger to be drilled is placed on the surface of the placement plate 313, the electric telescopic rod 402 drives the clamping plates 401 on both sides to move toward the surface of the side plate of the heat exchanger. When the first clamping block 404 contacts the surface of the side plate of the heat exchanger, the electric telescopic rod 402 continues to move, compressing the first spring 405, and the first tooth plate 403 moves backward, driving the first gear 406 to rotate clockwise, thereby driving the second tooth plates 407 on both sides to move closer, driving the second clamping blocks 408 on both sides to move closer, and drilling the side plate of the heat exchanger. The clamping and fixing are convenient for use. When the first motor 305 drives the lifting plate 301 to descend, the pressing plate 413 is pressed on the surface of the heat exchanger side plate, and as the lifting plate 301 continues to descend, the second spring 414 is continuously compressed, so that the pressing plate 413 is tightly attached to the surface of the heat exchanger side plate, and the heat exchanger side plate is longitudinally fixed to avoid the vibration generated during drilling and cause drilling deviation, thereby ensuring the drilling quality. At the same time, the connecting rod 411 drives the piston 410 to move upward, injects the air in the air cavity 409 into the air pipe 416, and is sprayed to the surface of the drill bit 307 by the air collecting hood 415, so as to assist in heat dissipation of the drill bit 307.

Subsequently, the first motor 305 can drive the first screw rod 304 to rotate, thereby driving the lifting plate 301 to be lifted and lowered through the first threaded block 303, and driving the drill bit 307 to rotate through the drilling rig 306, so as to drill holes in the heat exchanger side plate, which is convenient for use.

[0047] The cutting fluid in the liquid storage tank 501 is pumped into the water pipe 504 through the water pump 502, and is sprayed toward the surface of the drill bit 307 through the nozzle 503, so as to dissipate heat and lubricate the drill bit 307, and flush the drilling debris. The drilling debris is flushed to the surface of the processing table 2 by the cutting fluid, and flows into the chip removal groove 505, and the debris is filtered through the filter hole 506. When the drilling is completed, the lifting plate 301 rises, driving the third tooth plate 514 to move up synchronously, driving the one-way gear 512 and the rotating shaft 508 to rotate counterclockwise, so that the debris in the chip removal groove 505 is scraped into the chip collection box 507 through the scraper 510, which is convenient for cleaning.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0049] It should be noted that the first motor 305, the drilling rig 306, the second motor 312, the third motor 316, the electric telescopic rod 402 and the water pump 502 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
