Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger with a dirt washing function. Background Art

[0002] A heat exchanger (also called a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction and is widely used in the field of heating. Shell and tube heat exchangers are mainly composed of a shell, a tube bundle, a tube sheet and a head. The shell is mostly circular and contains parallel tube bundles or spiral tubes. Both ends of the tube bundle are fixed to the tube sheet. Existing shell and tube heat exchangers lack the function of automatic cleaning. Dust easily accumulates on the surface after long-term use, and manual cleaning is time-consuming and labor-intensive.

[0003] After searching, the Chinese patent publication number is CN212431909U, which discloses a shell and tube heat exchanger with automatic cleaning function. When cleaning the surface of the heat exchanger, the moving block is driven to move by the telescopic mechanism so that the bristles on the cleaning frame abut against the surface of the heat exchanger body. At this time, the motor is controlled to drive the slider to move left and right, and the cleaning frame is used to clean the surface of the heat exchanger body. A spray mechanism is provided to spray and rinse the surface of the heat exchanger to further improve the cleaning efficiency.

[0004] However, during use of the above patent, although a cleaning rack is provided to clean the surface of the heat exchanger, after the cleaning rack is used to clean the surface of the heat exchanger, stains will remain on the surface of the heat exchanger, reducing the cleaning effect.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-Figure 4 As shown, a heat exchanger with a dirt flushing function includes a base 1, two support plates 101 are welded on the top of the base 1, a heat exchanger 102 is installed in the support plate 101, a water storage tank 103 is opened on the top of the base 1, a moving mechanism is installed on the top of the support plate 101, a spraying mechanism and a sweeping mechanism are arranged below the moving mechanism, and a cleaning mechanism is arranged below the sweeping mechanism.

[0025] The spray mechanism includes a water tank 301, which is connected to the outer wall of the support plate 101 by bolts. The bottom of the water tank 301 is connected to a water pump 302 by bolts. The bottom of the storage plate 401 is connected to a spray head 304 by bolts. A telescopic tube 303 is threadedly connected between the water pump 302 and the spray head 304. Through the movement of the water pump 302, water is pumped out of the water tank 301, transported to the spray head 304 through the telescopic tube 303, and sprayed to the surface of the heat exchanger 102 through the spray head 304 to rinse the dirt on the surface of the heat exchanger 102.

[0026] The cleaning mechanism includes a storage plate 401, which is connected to the bottom of the moving block 204 by bolts. The storage plate 401 is a T-shaped plate made of aluminum alloy. A bidirectional lead screw 402 is installed at the bottom of the storage plate 401 through a bearing seat. A second motor 403 is connected to the bottom of the storage plate 401 by bolts. The output shaft of the second motor 403 is connected to the bidirectional lead screw 402 by a coupling. Two sliding blocks 404 are threadedly connected to the bidirectional lead screw 402. The sliding block 404 is slidably connected to the bottom of the storage plate 401. A bottom plate 405 is connected to the bottom of the sliding block 404 by bolts. A cleaning brush 406 and a sponge block 407 are connected to the bottom of the bottom plate 405 by screws. The sponge block 407 is behind the cleaning brush 406 and moves through the second motor 403 to drive the bidirectional lead screw 402 to rotate, thereby driving the two sliding blocks 404 to approach each other, thereby driving the cleaning brush 406. The sponge block 407 moves toward the heat exchanger 102 until it abuts against the outer wall of the heat exchanger 102. The moving mechanism includes a mounting plate 201, which is welded to the top of the support plate 101. The outer wall of the support plate 101 is connected with a first motor 202 by bolts. A first lead screw 203 is rotatably connected between the two support plates 101 through a bearing. The output shaft of the first motor 202 is connected to the first lead screw 203 through a coupling. A moving block 204 is threadedly connected to the first lead screw 203. The moving block 204 is slidably connected to the bottom of the mounting plate 201. The movement of the first motor 202 drives the first lead screw 203 to rotate, thereby driving the moving block 204 to move, and then driving the cleaning mechanism to move, so as to clean the surface of the heat exchanger 102. After the cleaning brush 406 cleans, the sponge block 407 will wipe the stains on the surface of the heat exchanger 102, thereby further improving the cleaning effect.

[0027] The cleaning mechanism includes an electric push rod 501, which is installed on the inner wall of the support plate 101 through a bracket. The output shaft of the electric push rod 501 is connected to the intermediate plate 502 through a thread. The intermediate plate 502 is slidably connected to the inner wall of the support plate 101. The top of the intermediate plate 502 is connected to a connecting plate 503 through bolts. The connecting plate 503 is a U-shaped plate made of stainless steel. Two extrusion plates 504 are welded on the top of the connecting plate 503. A plurality of water filtering holes 505 are opened on the extrusion plate 504. The movement of the electric push rod 501 drives the intermediate plate 502 to move up along the inner wall of the support plate 101, thereby driving the connecting plate 503 to move up, and then driving the two extrusion plates 504 to move up, so as to squeeze the sponge block 407 and squeeze the sewage from the water filtering holes 505 into the water storage tank 103.

[0028] Working principle: When the surface of the heat exchanger 102 needs to be cleaned, the second motor 403 moves, driving the bidirectional lead screw 402 to rotate, thereby driving the two sliding blocks 404 to approach each other, and then driving the cleaning brush 406 and the sponge block 407 to move toward the heat exchanger 102 until they abut against the outer wall of the heat exchanger 102. Then the water pump 302 moves to pump water out of the water tank 301, and transports it to the spray head 304 through the telescopic tube 303. The water is sprayed onto the surface of the heat exchanger 102 through the spray head 304. Then the first motor 202 moves, driving the first lead screw 203 to rotate, thereby driving the moving block 204 moves, thereby driving the cleaning mechanism to move, so as to clean the surface of the heat exchanger 102. After the cleaning brush 406 cleans, the sponge block 407 will wipe the stains on the surface of the heat exchanger 102, further improving the cleaning effect. During the cleaning process, the spilled sewage will flow into the water storage tank 103. After the cleaning is completed, the electric push rod 501 moves, driving the middle plate 502 to move up along the inner wall of the support plate 101, thereby driving the connecting plate 503 to move up, and then driving the two squeezing plates 504 to move up, so as to squeeze the sponge block 407 and squeeze the sewage from the water filter hole 505 into the water storage tank 103.
