Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a construction waste proportioning and feeding device for cement production. Background Art

[0002] Most of the construction waste is composed of soil, sand, gravel, bricks and tiles, and concrete fragments. These materials are the main components for recycling, and the aggregate prepared using these recycled materials is recycled aggregate.

[0003] At present, in the production and screening process of recycled aggregates, it is impossible to screen and mix the materials at the same time. Different machines need to be operated, and the steps are cumbersome, resulting in low mixing efficiency.

[0004] Therefore, we propose a construction waste proportioning feeding device for cement production to solve the existing problems. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] 1. During the use of the construction waste proportioning feeding device for cement production of the utility model, the crushed aggregates of the construction waste to be screened enter the top of the screen plate through the material pipe, the screen plate is controlled to vibrate, and the particles that meet the standards pass through the screen plate, and the particles that do not meet the standards slide into the collection bucket under the action of gravity for collection;

[0020] 2. The screened aggregate enters the tank. During this process, the rotating plate is controlled to rotate so that the top of the rotating plate is against one side of the inner wall of the tank, thereby closing one of the two spaces separated by the partition below. The screened aggregate falls into the other chamber. When the aggregate in the chamber accumulates to a specified weight, the weighing sensor detects a signal to control the corresponding cylinder to work, thereby pulling the corresponding slide plate open, and the aggregate in the chamber is delivered to the specified position. After the aggregate in the chamber has finished falling, the corresponding slide plate is controlled to close the chamber.

[0021] 3. When the slide plate is pulled open, the rotating plate is controlled to deflect in the opposite direction to open the chamber where the aggregate has not fallen, and close the other chamber. The screened aggregate slides into the opened chamber. This process is repeated to achieve screening and proportioning at the same time. The screening action and proportioning action are integrated to achieve the purpose of synchronous operation of the whole machine. BRIEF DESCRIPTION OF THE DRAWINGS

The particles that meet the standards pass through the screen plate 11, and the particles that do not meet the standards slide into the collection bucket 14 under the action of gravity for collection;

[0033] The screened aggregate enters the tank 7. During this process, the rotating plate 12 is controlled to rotate so that the top of the rotating plate 12 abuts against one side of the inner wall of the tank 7, thereby closing one of the two spaces separated by the partition 3 below, and the screened aggregate falls into the other chamber. When the aggregate in the chamber accumulates to a specified weight, the weighing sensor 15 detects a signal to control the corresponding cylinder 2 to work, thereby pulling the corresponding slide 4 open, and the aggregate in the chamber is delivered to the specified position. After the aggregate in the chamber has finished falling, the corresponding slide 4 is controlled to close the chamber.

[0034] When the slide plate 4 is pulled open, the rotating plate 12 is controlled to deflect in the opposite direction to open the chamber where the aggregate has not fallen, and close the other chamber, and the screened aggregate slides into the opened chamber. This process is repeated, so that the screening and proportioning of materials can be achieved at the same time, and the screening action and the proportioning action are integrated to achieve the purpose of synchronous operation of the whole machine.
