Description

Technical Field

[0001] The present application relates to the technical field of feeding devices for producing acrylic emulsions, and in particular to a feeding device for producing acrylic emulsions. Background Art

[0002] Acrylic emulsion is an aqueous dispersion of cement-based high molecular polymers with anti-corrosion, anti-chloride ion penetration, aging resistance and corrosion resistance. It is suitable for steel structures such as oceans, sluices, waterfalls, port projects, roads, bridges, metallurgy, chemicals, industrial floors and civil buildings. Acrylic emulsion is also resistant to corrosion by chemical media such as dilute acid, urea and benzene. In the production process of acrylic emulsion, it is usually necessary to add additives to the raw materials to accelerate the molding of acrylic emulsion.

[0003] For example, a Chinese patent (publication number: CN214636002U) discloses a raw material adding device for the production of acrylic emulsion, including a mixing kettle, the upper end face of the mixing kettle is fixedly connected to a feed pipe, the lower end face of the mixing kettle is fixedly connected to a delivery pipe, the lower end face of the delivery pipe is fixedly connected to a reactor, the lower end face of the reactor is fixedly connected to a support column, the upper end face of the mixing kettle is fixedly connected to a motor, the output shaft of the motor extends to the interior of the mixing kettle and is fixedly connected to a first spiral conveying blade, the inner wall of the delivery pipe is provided with a fixed plate, a rotating plate is provided above the fixed plate, and a second spiral conveying blade is fixedly connected below the rotating plate, the upper end of the second spiral conveying blade is rotatably connected to the interior of the fixed plate, so that the raw materials can be evenly stirred and the material can be supplemented without affecting the temperature inside the reactor.

[0004] However, the above search patent still has some shortcomings. When mixing raw materials and additives, it is not convenient to add raw materials intermittently to coordinate stirring. Adding too much raw materials and additives at one time will greatly reduce the stirring and mixing effect and efficiency, which is inconvenient to use. Therefore, a feeding device for acrylic emulsion production is proposed to solve the above problems. Utility Model Content

At the same time, the control component and the stirring structure share a starting motor, thereby being able to automatically control the addition when the mixing kettle stirs the raw materials and additives, thereby improving the utilization rate of power and further increasing the practicality of the device.

[0011] Furthermore, the control component also includes a guide block fixed on the bottom surface of the extrusion plate, a slider fixed on the bottom surface of the extrusion rod and a spring fixed on the back of the slider.

[0015] Furthermore, a support seat is fixed on the bottom surface of the mixing kettle, a material delivery pipe is fixedly connected to the bottom surface of the mixing kettle, and a glass observation window is fixed on the front surface of the mixing kettle.

The two feeding bins are respectively located on the left and right sides of the rectangular bin. The top surface of the feeding bin is threadedly connected with a dust cover, and the feed pipe is a rubber tube with a certain elasticity.

[0018] The above technical solution makes it easy to add raw materials and additives into the feeding bin, and the dust cover can be used to prevent dust from falling and affecting the quality of the raw materials and additives.

[0019] Furthermore, the extrusion rod is arranged between the two extrusion plates, and the left and right ends of the extrusion rod are rotatably connected with rollers. The left and right sides of the rectangular bin are provided with sliding holes for sliding connection of the extrusion plates, and the two feeding pipes are respectively located between the two groups of extrusion plates and the fixed plate.

[0020] By adopting the above technical solution, the roller is arranged to facilitate the squeezing rod to squeeze the two squeezing plates to move away from each other.

[0021] Furthermore, the guide groove is used for allowing the guide block to slide left and right inside the guide groove, the slide block is used for allowing the slide block to slide back and forth inside the slide groove, and the spring is arranged inside the slide groove.

The device has better practicality and is more convenient for popularization and use.

[0025] 2. When the feeding device for the production of acrylic emulsion is in use, the control component can intermittently control the two feeding pipes to feed and stop at the same time. At the same time, the control component and the stirring structure share a starting motor, so that the feeding can be automatically controlled when the mixing kettle stirs the raw materials and additives, thereby improving the utilization rate of power and further increasing the practicality of the device.
