DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] As Figures 1-2 The lower end surface of the portable cloth bag filter 1 is provided with a drain pipe 102, and the upper end surface of the portable cloth bag filter 1 is provided with an inlet pipe 101. The portable cloth bag filter 1 is arranged, so that the water pump 301 can be used to draw the boiler water collected in the water guide bucket 304 into the portable cloth bag filter 1, and the boiler water is filtered by the filter cloth bag 203 and then discharged through the drain pipe 102, so that the boiler water can be reused, and the impurities in the boiler water can be filtered, avoiding the damage of the boiler caused by too many impurities in the boiler water.

[0022] Further, the inner surface of the portable cloth bag filter 1 is provided with a connecting ring 2, and the upper end surface of the connecting ring 2 is provided with a positioning hole 201. The positioning hole 201 is arranged, so that the filter cloth bag 203 can be positioned and disassembled conveniently.

[0023] Further, the inner surface of the positioning hole 201 is slidably provided with a plug rod 204, the upper end surface of the plug rod 204 is provided with a pull ring 202, and the inner surface of the pull ring 202 is provided with a filter cloth bag 203. The pull ring 202 is arranged, so that the filter cloth bag 203 can be cleaned and replaced regularly through the pull ring 202.

[0024] As Figures 3-4 The end surface of the water inlet pipe 101 is provided with a connecting pipe 3, and the lower end surface of the connecting pipe 3 is provided with a water pump 301, the input end of the water pump 301 is installed with a water suction pipe 302, and the lower end of the water suction pipe 302 is provided with a water guide bucket 304. The advantage of this setting is that the boiler water in the water guide bucket 304 can be introduced into the inside of the portable cloth bag filter 1 for filtration through the setting of the water pump 301.

[0025] Further, the upper left side of the water guide bucket 304 is provided with a water guide pipe 303, and the lower end outer surface of the water guide bucket 304 is provided with a sewage pipe 305. The advantage of this setting is that the impurities accumulated at the bottom of the water guide bucket 304 can be discharged through the setting of the sewage pipe 305.

[0026] Further, the lower end surface of the water guide bucket 304 is installed with a driving motor 308, and the output end of the driving motor 308 is provided with a support frame 307, the upper end surface of the support frame 307 is provided with a scraper 306 on both sides, and the scraper 306 and the inner surface of the water guide bucket 304 are in frictional contact.
