Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the following detailed description of the embodiments of the present application will be made with reference to the accompanying drawings.

Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Fig. 1 is a schematic diagram of a structure of a pipeline inside a heat exchanger, wherein the heat exchanger internally comprises a large number of long and narrow heat exchange pipes, dirt is easily deposited on the inner wall of the pipeline, bacteria are bred, and a large amount of cost and time are input due to disassembly and cleaning. The heat exchanger belt cleaning device that this scheme provided can let artifical manual washing dirt under the condition of not dismantling the pipeline, the life of extension heat exchange tube. As shown in fig. 2, the structural schematic diagram of the heat exchanger cleaning device provided in the embodiment of the present application is shown, and includes a descaling gun head (10), a water inlet hose (20), a high-pressure water pump (30), and a water tank (40). The length of the descaling gun head (10) is set according to the length of the heat exchange tube, and the diameter of the descaling gun head (10) is slightly smaller than the diameter of the pipeline, so that the descaling gun head can conveniently enter and exit to shovel off dirt.

The descaling gun head (10) comprises a conical cutter head (11) and a metal connecting pipe (12), wherein the conical cutter head (11) is of a titanium alloy structure and high in hardness, and the top part of the conical cutter head is a conical head (111) which is enough for breaking dirt in a pipeline. The bottom is a cylindrical body (112) part which is convenient to be welded with a metal connecting pipe (12). The metal connecting pipe (12) is a hollow pipe, and the bottom end of the conical cutter head (11) is embedded into the water outlet end and welded. However, because high-pressure water flow is needed to be sprayed for cleaning, a water outlet is needed to be arranged, so that right-angle notches (113) are symmetrically formed in the conical cutter head (11), two water spraying ports (13) are formed between the direct notches and the water outlet end of the metal connecting pipe (12), and the high-pressure water flow sprayed out through the water spraying ports (13) can flush away the shoveled dirt.

The tail end of the metal connecting pipe (12) is provided with a mounting thread, the tail part is sleeved with a water inlet hose (20), the water inlet hose (20) is connected into a water tank (40), and a high-pressure water pump (30) is additionally arranged between pipelines. The high-pressure water pump (30) can pressurize the water in the water tank (40) to improve the impact force for removing dirt. In addition, because the high-pressure squirt needs to stretch into the pipeline inner wall, need set up the on-off control return circuit, consequently this scheme adds to high-pressure water pump (30) and establishes foot switch (50). When the operator puts the gun head deep into the pipe wall, the high-pressure water gun is started by stepping on the foot switch (50). Not only can deposit the dirt in the pipeline of heat exchange tube, still can only remain the bacterium, therefore this scheme still adds the washing liquid in water tank (40), mixes the hydrochloric acid that has certain proportion and concentration in the washing liquid, and salicylic acid and hypochlorous acid can dissolve the dirt on the one hand, can also disinfect to the pipeline inner wall, avoids breeding the bacterium.

In conclusion, the titanium alloy descaling gun head is welded on the metal connecting pipe, dirt deposited on the inner wall of the pipeline can be removed, and a water outlet formed by the bottom of the descaling gun head and the water outlet of the metal pipe after a right-angle notch is formed in the bottom of the descaling gun head can be cleaned by water jet while descaling; the high-pressure water pump can pressurize water in the water tank, the cleaning effect is enhanced, the pedal switch is arranged to control the water flow to be sprayed, cleaning liquid added into the water body can be used for descaling and sterilizing the inner wall of the pipeline, and the service life of the pipeline of the heat exchanger is prolonged.
