Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, in particular to a mixing device which is convenient for spraying an anti-corrosion coating inside. Background Art
[0002] After a long period of use, the internal surface of an uncoated kettle will corrode due to factors such as chemical erosion and material friction. This not only significantly shortens the service life of the equipment, but also contaminates the mixed material with impurities produced by corrosion, reduces product purity, and may even cause safety accidents, such as environmental pollution and personal injury caused by material leakage.
[0003] At present, most stirring and mixing equipment uses electrostatic powder spray guns to complete coating spraying. There are some limitations in the spraying process production, which affects the process continuity of the spray coating and may lead to subsequent quality problems. At the same time, since continuous high-temperature heating is required during the spraying process, the spraying temperature is high, and the insulation material is easily oxidized and blackened at this temperature. The air in the insulation layer of the kettle body expands after heating, causing the insulation layer cylinder to crack and damage the equipment.
[0004] Therefore, it is urgent to develop a mixing equipment that is convenient for internal spraying of anti-corrosion coatings. Utility Model Content
[0005] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a mixing equipment that is convenient for spraying anti-corrosion coating internally, thereby designing a full coating spray design for the interior of the kettle body, which can provide all-round performance protection for the interior of the equipment, and the spraying process will not cause damage to the insulation layer of the kettle body due to high temperature.
[0006] The technical solution adopted by the present invention is as follows: a mixing device that is convenient for spraying an anti-corrosion coating on the inside, comprising a kettle body, a kettle cover arranged on the top of the kettle body, a first anti-corrosion coating arranged on the inner surface of the kettle body, and heat dissipation openings arranged on the outside of the insulation layer of the kettle body; a second anti-corrosion coating is arranged on the inner surface of the kettle cover; a kettle cover top mounting seat is arranged on the top of the kettle cover, and the top surface of the kettle cover top mounting seat is connected to the sealing member mounting seat via connecting bolts; a sealing member is arranged in the sealing member mounting seat, and the sealing member is arranged around the contact end between the main shaft of the bearing cavity and the kettle cover top mounting seat to maintain sealing.
[0007] As a further improvement of the above technical solution:
[0008] Preferably, the structure of the sealing member mounting seat is an oil seal seat that fits tightly with the top surface of the kettle cover top mounting seat.
[0009] Preferably, an oil seal is installed in the oil seal seat.
[0010] Preferably, an O-ring is additionally provided on the plane of the oil seal seat.
[0011] Preferably, the connecting bolts pass through the upper surface of the oil seal seat and the inner holes of the kettle cover top mounting seat in sequence, so that the oil seal seat and the kettle cover top mounting seat are tightly fitted.
[0012] Preferably, the first anti-corrosion coating and the second anti-corrosion coating are the same coating structure; the coating structure comprises: a primer layer in contact with the metal surface of the kettle body, the primer layer is used to enhance the bonding force; a coating layer is laid on the primer layer;
[0013] More preferably, the coating layer is a PFA coating layer.
[0014] Preferably, the kettle cover is a cover body with an arc-shaped top surface, and a kettle cover top mounting seat is provided at the middle position of the arc top surface of the kettle cover.
[0015] The beneficial effects of the utility model are as follows:
[0016] The utility model has a compact structure. By adding anti-corrosion coatings to the interior of the kettle body and the cover, all-round spraying is carried out without coating quality problems and precision matching problems, and all-round performance protection can be provided for the interior of the equipment.
[0017] The utility model also has the following advantages:
[0018] (1) The utility model opens heat dissipation holes on the outside of the insulation layer of the kettle body. The air in the insulation layer expands after being heated and is discharged from the holes, which will not cause the insulation layer cylinder to crack. After the coating is sprayed and the equipment is cooled, the insulation material is filled and the holes are patched, which makes assembly simple.
[0019] (2) The utility model connects the top mounting seat of the kettle cover with the sealing member mounting seat through connecting bolts, ensuring that the O-ring is pressed tightly against the top surface of the top mounting seat of the kettle cover to ensure sealing.
