Technical Field
[0001] This utility model belongs to the technical field of heat exchanger maintenance equipment, specifically a rust removal device for plate heat exchangers. Background Technology
[0002] Plate heat exchangers are high-efficiency heat exchangers composed of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the various plates, and heat is exchanged through the plates. During long-term use, rust is easily generated inside due to rust deposits, media corrosion, scaling, etc., which affects the heat exchange efficiency and service life. Therefore, it is necessary to remove rust from the heat exchanger.
[0003] Currently, existing rust removal devices include various methods such as chemical rust removal and physical rust removal. Chemical cleaning and rust removal devices use acidic or neutral rust removers to dissolve rust layers, making them suitable for cleaning internal channels or complex structures.
[0004] However, when existing devices are in use, the residual acidic cleaning agent may corrode the plates, leading to perforation or intergranular corrosion, which affects the service life of the heat exchanger. Therefore, a rust removal device for plate heat exchangers is proposed to address the above problems. Summary of the Invention
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a rust removal device for plate heat exchangers.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figure 1 - Figure 3 This utility model provides a rust removal device for a plate heat exchanger, including a rust removal device body 10, on which a plate heat exchanger body 11 is threadedly connected; a top plate 21 is fixedly connected to the top of the plate heat exchanger body 11; a motor 22 is fixedly connected to the upper surface of the top plate 21; a first through hole 23 is opened in the middle of the top plate 21; the output shaft of the motor 22 passes through the first through hole 23; a turbine fan 25 is fixedly connected to the output shaft of the motor 22. During operation, after chemical rust removal of the plate heat exchanger body 11, the motor 22 is turned on, and the output shaft of the motor 22 rotates, driving the turbine fan 25 to rotate. The turbine fan 25 blows the waste liquid residue between the heat exchanger plates downwards to avoid waste liquid residue.
[0027] Furthermore, such as Figure 2 As shown, an electronic generator 12 is fixedly connected to the main body 10 of the rust removal device; the electronic generator 12 is fixedly connected to the plate heat exchanger 11; a slot 24 is provided on the bottom surface of the top plate 21; the turbine fan 25 rotates in the slot 24. When working, the electronic generator 12 releases electrons into the water to remove rust from the plate heat exchanger 11, and the slot 24 provides rotation space for the turbine fan 25.
[0028] Furthermore, such as Figure 1 and Figure 4 As shown, a collection plate 26 is fixedly connected to the bottom of the plate heat exchanger body 11; a collection tank 27 is provided on the collection plate 26, and the collection tank 27 can collect the waste liquid residue generated during the rust removal process during operation.
[0029] Furthermore, such as Figure 1 and Figure 4 As shown, the plate heat exchanger body 11 has sliding grooves 28 on both sides of the bottom end; a filter plate 29 is slidably placed in the sliding groove 28. During operation, the filter plate 29 can filter the metal residue in the waste liquid. The sliding groove 28 facilitates the pulling of the filter plate 29.
[0030] Furthermore, such as Figure 3 As shown, the filter plate 29 has limit holes 31 at both ends; there are two limit holes 31 located at the front end of the filter plate 29. During operation, the limit holes 31 are used to cooperate with the limit block 35 to fix the filter plate 29.
[0031] Furthermore, such as Figure 4 and Figure 5 As shown, the top surface of the slide 28 is provided with an installation groove 32; a spring 33 is fixedly connected in the installation groove 32; a connecting plate 34 is fixedly connected to the other end of the spring 33; a limiting block 35 is fixedly connected to the bottom surface of the connecting plate 34. When working, the elastic force of the spring 33 can push the connecting plate 34 to drive the limiting block 35 to move downward, so that the limiting block 35 is engaged in the limiting hole 31.
[0032] Furthermore, such as Figure 5 As shown, a connecting rope 36 is fixedly connected to the upper surface of the connecting plate 34; a second through hole 37 is provided on one side of the mounting groove 32; the connecting rope 36 passes through the second through hole 37; a pull plate 38 is fixedly connected to one end of the connecting rope 36. During operation, pulling the pull plate 38 can drive the connecting plate 34 to move upward through the connecting rope 36, so that the limiting block 35 disengages from the limiting hole 31, making it easier to remove the filter plate 29 for cleaning.
[0033] Working principle: After the rust removal device body 10 chemically removes rust from the plate heat exchanger body 11, the motor 22 is turned on. The output shaft of the motor 22 rotates, driving the turbine fan 25 to rotate. The turbine fan 25 blows the waste liquid residue between the plates of the plate heat exchanger downwards. The waste liquid is filtered by the filter plate 29 and falls into the collection tank 27 on the collection plate 26 to avoid waste liquid residue. The electron generator 12 releases electrons into the water to remove rust from the plate heat exchanger 11. The slot 24 provides rotation space for the turbine fan 25. The collection tank 27 can collect the waste liquid residue generated during the rust removal process. The filter plate 29 can filter the metal residue in the waste liquid. The design of the chute 28... The filter plate 29 is designed to be easily pulled out. The limiting hole 31 is used to fix the filter plate 29 in conjunction with the limiting block 35. When the filter plate 29 needs to be disassembled, the pulling plate 38 is pulled away from the plate heat exchanger body 11. The connecting rope 36 moves to the outside of the second through hole 37, which causes the spring 33 to retract. The connecting plate 34 moves upward to the mounting groove 32, which causes the limiting block 35 to exit from the limiting hole 31. This makes it easier to remove the filter plate 29 for cleaning. The limiting hole 31 is used to fix the filter plate 29 in conjunction with the limiting block 35, which improves the efficiency of disassembling and installing the filter plate 29 and makes it easier to clean the residue on the filter plate 29.
