[0030] Preferably, it also includes a plurality of heat sinks 23, which are respectively fixedly mounted in the first cavity 7 and the third cavity 9, and one side of the plurality of heat sinks 23 is fixedly mounted on the side wall of the partition 6 at an upper and lower interval, the liquid inlets at the tops of the first cavity 7 and the third cavity 9 are respectively connected to the liquid outlet pipe 25 through the first liquid infusion pipe 24, and the water inlet of the liquid outlet pipe 25 is connected to the water outlet of the treatment box 10, the liquid discharge ports at the tops of the first cavity 7 and the third cavity 9 are respectively connected to the liquid return pipe 27 through the second liquid infusion pipe 26, and the water outlet of the liquid return pipe 27 is connected to the water inlet of the treatment box 10.

[0031] The working principle and beneficial effects of the above technical solution are:

[0032] The present invention provides a corrosion-resistant boiler structure which mainly comprises a boiler body 2, a descaling mechanism 4, a heat exchange mechanism 5 and a water cooling mechanism 3. The descaling mechanism 4 is arranged inside the boiler body 2, which can timely remove impurities such as scale settled at the bottom of the boiler, and effectively ensure the quality of the water body inside the boiler body 2. Secondly, the heat exchange mechanism 5 realizes high efficiency of heat exchange of the boiler water body, and at the same time avoids corrosion caused by scale adhesion on the heat exchange mechanism 5. The water cooling mechanism 3 is arranged to effectively cool the side wall of the boiler body 2, and protect the side of the boiler body 2 from high temperature damage. The above invention can effectively reduce the influence of scale corrosion inside the boiler body 2, and at the same time protect the side wall of the boiler body 2 from damage by high-temperature flue gas.

[0033] By means of the water cooling mechanism 3, the processing box 10 arranged on the top of the fixed frame 1 is filled with coolant. When the side wall of the boiler body 2 needs to be cooled, the driving motor 12 fixedly installed in the shell 11 is started to drive the driving shaft 13 fixedly connected to the output shaft of the driving motor 12 to rotate, so that the several stirring blades 14 fixedly installed on the driving shaft 13 are rotated in the processing box 10, thereby mixing the coolant inside the processing box 10, so that the internally supplemented coolant and the circulating reflux coolant are fully mixed, and the heat dissipation of the coolant is accelerated; at the same time, the two heat dissipation components 16 arranged on the top of the processing box 10 are driven by the first pulley 15 fixedly installed on the driving shaft 13 to rotate the second pulley 21 in the heat dissipation component 16 through the belt 22 transmission pulley, thereby realizing the fixed connection with the second pulley 21 to rotate The shaft 18 rotates, so that the cooling fan 19 fixedly installed at the lower end of the rotating shaft 18 rotates, thereby accelerating the cooling and heat dissipation of the coolant inside the processing box 10. At the same time, the dustproof net 20 arranged on the side wall of the installation box 17 can effectively prevent dust in the air from entering the processing box 10 and contaminating the coolant; then the coolant is transported to the first cavity 7 and the second cavity 8 through the first infusion pipe 24 and the outlet pipe 25, and the cooling fins 23 arranged in the first cavity 7 and the second cavity 8 are cooled. The cooling fins 23 are fixedly installed on the side wall of the partition 6, and can conduct heat to the partition 6, thereby quickly reducing the temperature of the partition 6. The above-mentioned water-cooled wall can protect the boiler furnace wall from being burned by high-temperature flue gas. Since the coolant circulates inside the water-cooled wall, the temperature of the furnace wall can be effectively reduced to prevent the furnace wall from being damaged by high temperature.

[0034] The water cooling mechanism 3 mentioned above effectively protects the side wall of the boiler, so that the boiler furnace wall will not be corroded by high-temperature flue gas, while increasing the service life of the boiler, ensuring the safe and stable operation of the boiler, effectively reducing energy consumption, greatly improving the performance of the safe and stable operation of the corrosion-resistant boiler structure, and avoiding damage to the boiler side wall.

The collected scale and other impurities will fall into the auxiliary box 28, and then the first drive motor 29 embedded in the auxiliary box 28 drives the spiral feeding rod When it is necessary to discharge the scale and other impurities inside the boiler body 2, open the valve 35 on the drain pipe 34 to discharge the scale and other impurities settled in the auxiliary box 28, and close the valve 35 after the discharge is completed.

The above-mentioned heat exchange mechanism 5 can effectively avoid a large amount of impurities attached to the heat exchange mechanism 5 that are difficult to remove, thereby causing corrosion of structures such as heat exchange devices, and can also improve the heat exchange efficiency of the boiler.
