Description

Technical Field

[0001] The utility model belongs to the technical field of feeding materials for calcium oxide production, in particular to a feeding device for calcium oxide production. Background Art

[0002] Calcium oxide is an inorganic compound with the chemical formula CaO, commonly known as quicklime. Its physical properties are white powder on the surface, grayish white if it is impure, light yellow or gray if it contains impurities, and hygroscopic. During the digestion process of calcium oxide, calcium oxide and water need to be put into the digestion machine for reaction to achieve the effect of digestion processing of calcium oxide.

[0003] The utility model with announcement number CN219150065U discloses a feeding device for calcium oxide production, including a feeding barrel, a feeding port is arranged on the top of the feeding barrel, a discharge port is arranged on the bottom of the feeding barrel, and a solenoid valve is installed at the discharge port; a quantitative weighing mechanism is installed at the bottom of the feeding barrel, and the quantitative weighing mechanism includes an outer box body, the top of the outer box body is connected with the discharge port, and the bottom of the outer box body is provided with a lower discharge port, support blocks are fixedly installed on the inner wall at the four corners of the middle end of the outer box body, a weighing sensor is installed on the top of the support block, and a weighing box is installed on the top of the four weighing sensors. The weighing box is a T-shaped structure and is provided with openings at the top and bottom. The bottom of the weighing box is connected to a sealing cover plate through a hinge shaft, and a servo motor is installed on one side of the weighing box. Transmission wheels are installed on the output shaft of the servo motor and the hinge shaft connected to the sealing cover plate, and transmission belts are sleeved on the two transmission wheels; a conveying mechanism is installed at the bottom of the lower discharge port.

[0004] In the process of implementing this application, it was found that the technology has the following problems: in the above patent documents, calcium oxide can be dropped from the discharge port into the weighing box, at which time the weighing sensor weighs the weight of the calcium oxide. When the set amount is reached, the controller controls the sealing cover to open, so that the calcium oxide falls to the bottom of the outer box for processing; however, in the actual operation process, the weight of the calcium oxide raw material added to the weighing box may exceed the set value, and the sealing plate will not open. At this time, if you want to open the sealing plate, the weight of the material in the weighing box must reach the preset value of the controller. Therefore, it is necessary to reduce the raw material in the weighing box, and this requires the staff to slowly take out a part of the material from the weighing box from the discharge port, which is inconvenient to operate and affects the quantitative feeding efficiency.

[0005] For this reason, a feeding device for calcium oxide production is proposed. Utility Model Content
