Description

Technical Field

[0001] This utility model relates to the field of epoxy zinc-rich primer production technology, specifically to an epoxy zinc-rich primer production equipment. Background Technology

[0002] Epoxy zinc-rich primer is a special coating made of epoxy resin and zinc powder as the main raw materials, thickeners, fillers, additives, solvents, etc. Zinc powder is the core functional material, and its high zinc content is the key to providing electrochemical protection. Epoxy resin acts as a binder to bind the zinc powder particles together and adhere them to the steel surface to form a paint film.

[0003] During the production of epoxy zinc-rich primer, it is necessary to use a mixing device to fully mix the raw materials. Due to the high density of zinc powder, it will quickly settle to the bottom of the tank if the mixing speed is insufficient. The zinc powder sedimentation will form zinc lumps that are difficult to disperse, thus affecting the efficiency of mixing and production.

[0004] There is an urgent need for a production equipment for epoxy zinc-rich primer to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an epoxy zinc-rich primer production equipment to solve the problem of zinc powder easily settling and clumping as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an epoxy zinc-rich primer production equipment, comprising a mixing tank, baffles fixedly connected to the bottom ends of both sides inside the mixing tank, a bracket fixedly connected to the top end of the left side of the mixing tank, a spiral feeding pipe fixedly installed at the top end of the bracket, a spiral feeding shaft movably installed inside the spiral feeding pipe, a feeding motor fixedly installed on the left side of the spiral feeding pipe, a feed hopper fixedly installed on the left side of the top end of the spiral feeding pipe, a feed pipe fixedly connected to the right side of the bottom end of the spiral feeding pipe, a first motor fixedly installed at the top end of the mixing tank, a first stirring shaft fixedly connected to the output end of the first motor, a second motor provided to the right side of the first motor, a drive gear fixedly connected to the output end of the second motor, a second stirring shaft movably installed at the top end inside the mixing tank, high-speed dispersing discs fixedly connected to both sides of the second stirring shaft, a driven gear fixedly connected to the outside of the second stirring shaft, mounting seats fixedly connected to the bottom ends of both sides of the first stirring shaft, a stirring rod installed inside the mounting seat, and a scraper fixedly connected to the bottom end of the stirring rod.

[0007] As a further technical solution of this utility model, the bottom end of the scraper is attached to the bottom end of the mixing tank, and the second stirring shaft is hollow and sleeved on the outside of the first stirring shaft.

[0008] As a further technical solution of this utility model, the driven gear is disposed on the left side of the driving gear, and the driving gear and the driven gear are meshed together.

[0009] As a further technical solution of this utility model, an inlet is provided on the right side of the top of the mixing tank, and a discharge pipe is fixedly installed at the bottom of the mixing tank.

[0010] As a further technical solution of this utility model, the bottom end of the feed pipe is fixedly connected to the top end of the mixing tank, and a solenoid valve is fixedly installed on the feed pipe.

[0011] As a further technical solution of this utility model, the output end of the feeding motor is fixedly connected to the screw feeding shaft, and the bottom end of the feeding hopper is fixedly connected to the top end of the screw feeding tube.

[0012] As a further technical solution of this utility model, the stirring rod is provided in two sets, and the front end of the mounting base is provided with mounting bolts.

[0013] As a further technical solution of this utility model, the mounting bolt is threaded through the mounting base and embedded inside the stirring rod to form a threaded connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the epoxy zinc-rich primer production equipment not only achieves the function of avoiding zinc powder settling to the bottom and the function of facilitating uniform feeding, but also achieves the function of facilitating disassembly and replacement. By incorporating a stirring rod, a high-speed dispersing disc, a first stirring shaft, a second stirring shaft, a first motor, a second motor, a drive gear, and a driven gear, the mixing mechanism utilizes a dual-shaft stirring structure. During mixing, the first motor drives the first stirring shaft to rotate slowly, which in turn drives a scraper to thoroughly stir the zinc powder at the bottom, preventing agglomeration. The second motor drives the drive gear to rotate, and the drive gear meshes with the driven gear to drive the second stirring shaft to rotate. The second stirring shaft then drives the high-speed dispersing disc to rotate at high speed, providing high shear force to break up agglomerates. This dual-shaft stirring structure enhances the efficiency of mixing and achieves the function of preventing zinc powder from settling. The zinc powder is fed into the spiral feeding pipe from the feed hopper through a spiral feeding pipe, a feeding motor, a feeding hopper, a spiral feeding shaft, a feed pipe, and a solenoid valve. The feeding motor drives the spiral feeding shaft to rotate at a constant speed. The spiral feeding shaft can evenly transport the zinc powder to the feed pipe and discharge it into the mixing tank. The zinc powder is added slowly and evenly. This allows the zinc powder to be wetted by a liquid medium, preventing it from clumping and settling to the bottom. This structure facilitates uniform feeding. The equipment is equipped with a stirring rod, a first stirring shaft, a mounting base, mounting bolts, and a scraper. The high zinc powder content acts as an abrasive, which quickly wears down the scraper and stirring rod, affecting the stirring efficiency. The stirring rod inside the equipment can be removed and replaced from the first stirring shaft. To remove it, simply unscrew the mounting bolts on the mounting base and move the stirring rod out of the mounting base. This structure facilitates disassembly and replacement, improving the durability of the equipment. Attached Figure Description
