Technical Field

The utility model relates to the technical field of concrete testing equipment, in particular to a feeding device for adjusting and reducing the water storage amount of cement fluidity.

Background Art

At present, the standard cement curing box used in the laboratories of the cement concrete industry consists of three parts: a box base, a box body and a box top. A humidifier is installed at the lower rear part of the box base to improve the fluidity of cement. If too much water is added, the fluidity of cement will increase and exceed the expected value, making it inconvenient to discharge the moisture in the cement. For this reason, we propose a feeding device that reduces the water storage capacity of cement fluidity.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to FIG1 , a feeding device for reducing the water storage amount of cement fluidity comprises a box body 1, a sampling port 13 is arranged on the side wall of the box body 1, a plug is spirally arranged on the sampling port 13, the material in the box body 1 can be sampled through the sampling port 13, a feeding pipe 2 is arranged on the side wall of the box body 1, cement and the like are put into the box body 1 for mixing, a moving plate 3 is slidably arranged in the box body 1, a filter hole 4 is opened on the moving plate 3, a water-permeable gauze 5 is fixed on the lower wall of the moving plate 3, and a connecting block 6 is connected to the upper wall of the moving plate 3. A hose 7 is installed, and the opening of the hose 7 is downward. The upper wall of the movable plate 3 is an inclined structure and is inclined toward the hose 7. The upper end of the hose 7 passes through the upper wall of the box body 1. The end of the hose 7 passing through the box body 1 is connected to the water pump. The upper wall of the movable plate 3 is connected with a connecting rod 8, and the connecting rod 8 slides through the upper wall of the box body 1, and an electric push rod 9 is installed on the top of the connecting rod 8. The electric push rod 9 is installed on the upper wall of the box body 1, and the movable plate 3 is driven down by the electric push rod 9, so that the movable plate 3 is pressed on the cement surface to squeeze out the moisture in the cement.

A mixing structure is provided in the box body 1, and the mixing structure includes a motor 10 installed on the lower wall of the box body 1. A rotating shaft 11 is connected to the motor 10. The rotating shaft 11 rotates and penetrates the lower wall of the box body 1. A spiral blade 12 is provided on the rotating shaft 11. The rotating shaft 11 is driven by the motor 10 to rotate, thereby driving the spiral blade 12 to rotate, so as to mix and stir the cement.

Embodiment: When in use, cement is sampled through the sampling port 13 to detect its fluidity. When there is too much water in the cement, the water in the cement needs to be discharged. The electric push rod 9 is started to drive the movable plate 3 to descend, press on the cement surface, and gradually press down to squeeze the cement. The water in the cement is separated through the breathable gauze 5, and the water passes through the filter hole 4 to the upper surface of the movable plate 3. Since the upper surface of the movable plate 3 is an inclined structure, the water on the upper surface of the movable plate 3 flows to the hose 7. By starting the water pump, the water on the movable plate 3 is sucked away by the water pump, thereby realizing the water in the cement. After the water is discharged, the cement is re-mixed through the mixing structure, and then sampled for detection.
