Description

TECHNICAL FIELD

[0001] The utility model relates to photoresist reaction kettle cleaning technical field, specifically, relate to a kind of cleaning device with extensive applicability. BACKGROUND

[0002] Currently, photoresist is prepared by reaction kettle, and the materials adhered and solidified on the kettle slurry and kettle wall need to be cleaned to ensure the subsequent use effect after the reaction kettle is used for a period of time. At this time, the inside of the reaction kettle needs to be sprayed and washed with solvent using the spray pipeline equipped on the kettle cover. However, some stubborn photoresist still adheres to the kettle slurry and kettle wall during the cleaning process, and the cleaning effect is generally poor. Therefore, the kettle slurry and kettle wall of the reaction kettle need to be manually cleaned using a cleaning brush before rinsing. After manual cleaning, the reaction kettle can be completely cleaned by rinsing with the spray head.

[0003] However, the height of the existing 100L or larger capacity reaction kettle is generally more than 1 meter, and the length of the cleaning brush is generally fixed. Therefore, it is not convenient for the staff to clean the adhered materials in the deeper part of the reaction kettle. In addition, the brush head and handle of the existing cleaning brush are straight line structures. Therefore, the cleaning brush cannot well fit the inner wall and kettle paddle of the reaction kettle during the cleaning process. As a result, other substances may be left in the reaction kettle, which may affect the quality of the subsequent photoresist product. In summary, the manual brushing process before the spray cleaning of the adhered materials in the reaction kettle needs to be improved. SUMMARY

[0007] The handle is fixedly connected to one end of the connecting roller, and the other end of the connecting roller is provided with an external thread.

[0008] The fixing assembly is in contact with the surface of the connecting roller, and the fixing assembly is manually locked with the kettle cover of the reaction kettle to limit the horizontal position of the connecting roller.

[0009] The two ends of the bent brush roller, the two ends of the straight roller, and the upper end of the brush head are provided with external threads.

[0010] The connecting roller, the brush roller, the straight roller, and the brush head are sequentially connected by a plurality of double internal thread sleeves. The brush head is adjusted and rotated under the action of the handle to be in contact with the kettle wall and the kettle slurry in sequence.

[0011] Further, the fixing assembly comprises a semicircular plate, a semicircle hole and a clamp,

[0012] The semicircle hole is arranged on the semicircular plate.

[0013] After the two semicircular plates are butted, the kettle cover of the reaction kettle is locked through the clamp, and the diameter of the circle hole formed by the butt joint of the two semicircle holes is equal to the diameter of the connecting roller.

[0014] Further, the main body of the brush head is in one of an oval shape, a spherical shape, a rounded rectangular shape and an inverted trapezoidal shape.

[0015] Further, the brush roller comprises a plurality of straight ends and a plurality of different bending degrees.

[0016] Further, the length of the straight roller is 30-35 cm.

[0017] Further, the handle is provided with an anti-skid pad.

[0018] Further, a spring washer is additionally arranged at the connection between the double internal thread sleeve and the external thread.
