[0019] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to Figure 1-3 The embodiment of the utility model discloses: a corrosion-resistant surface cooler, including a unit 1, a stainless steel circulation pipe 2 is provided on the unit 1, a stainless steel fixed pipe 3 is provided on the unit 1, the circulation pipe 2 is connected to the fixed pipe 3, and a water inlet pipe 4 and a water outlet pipe 5 are respectively provided at both ends of the fixed pipe 3, and the water inlet pipe 4 is provided with a filtering device to prevent impurities from entering the fixed pipe 3.

[0021] Specifically, the filtering device includes a filter screen 6, a fixed groove is provided on the water inlet pipe 4, one end of the filter screen 6 is arranged in the fixed groove, the other end of the fixed groove is provided with a maintenance channel connected to the outside, a maintenance cover 7 is provided in the maintenance channel through a bolt cover, the other end of the filter screen 6 resists the maintenance cover 7, a sealing gasket 10 is provided between the maintenance cover 7 and the water inlet pipe 4, a sealing groove 11 is provided around the water inlet pipe 4, one end of the sealing gasket 10 is located in the sealing groove 11, and the other end is located outside the sealing groove 11, the sealing gasket 10 resists the maintenance cover 7, a plurality of springs 12 are provided in the sealing groove 11, and the springs 12 are provided between the sealing gasket 10 and the inner wall of the sealing groove 11.

[0022] In order to improve the endurance of the filter 6, a brush 8 and a screw 9 are included. The brush 8 matches the width of the filter 6, and the brush 8 resists the filter 6. The screw 9 is rotatably penetrated on the maintenance cover 7. The screw 9 passes through the brush 8 and is threadedly transmitted with the brush 8. A limit rod (not shown in the figure) is provided on the brush 8. A limit channel (not shown in the figure) is opened on the water inlet pipe 4. The limit rod is arranged in the limit channel. A driving motor for driving the screw 9 to rotate is provided on the maintenance cover 7.

[0023] In order to facilitate the cleaning of impurities, a sewage outlet (not shown in the figure) is provided in front of the filter screen 6 , and a plug is connected to the inner thread of the sewage outlet, and the plug is located at the other end of the maintenance cover 7 .

[0024] Working principle:

[0025] The circulation pipe 2 and the fixed pipe 3 are replaced with stainless steel so that they will not be easily corroded in the peracetic acid environment, which is conducive to improving their service life, reducing the maintenance of the unit 1, and reducing the cost of use. When the unit 1 is in use, when cold water is passed from the water inlet pipe 4 to the inside of the unit 1, the filter 6 filters the impurities in the cold water, thereby preventing the impurities from entering the inside of the unit 1 and blocking the circulation pipe 2, which is conducive to the stable operation of the unit 1. At the same time, the drive motor works to drive the screw 9 to rotate, and the screw 9 and the brush 8 are threadedly driven, so that the brush 8 cleans the filter 6 up and down, so that impurities will not be attached to the filter 6, and the endurance of the filter 6 is improved. When the filter 6 and the brush 8 are to be repaired and replaced, the maintenance cover 7 is directly opened and taken out for replacement and maintenance. When the maintenance cover 7 is covered on the water inlet pipe 4, the spring 12 is compressed, and the spring 12 releases the elastic force, pushing the sealing gasket 10 to tightly resist the maintenance cover 7, so as to better ensure the seal.
