Technical Field

[0001] The utility model relates to the technical field of cement production equipment, in particular to a raw material proportioning device for cement production. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material, which becomes a slurry when mixed with water. It can harden in the air or in water, and can firmly bond sand, stone and other materials together.

[0003] For example, the utility model patent with announcement number CN212602589U discloses a cement batching device for a cement production line, which adds cement raw materials and ingredients into the cement raw material bin and cement batching bin respectively, and the second motor drives the stirring assembly to stir the materials, and then controls the discharge of materials through the raw material bin valve and the batching bin valve, and finally stirs and transports the mixed materials.

[0004] However, when the utility model is in use, it lacks a weighing component for the material, resulting in the inability to better control the amount of material when the material is mixed and proportioned, thereby affecting the proportioning effect. Therefore, a raw material proportioning device for cement production is urgently needed to be developed. Utility Model Content

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a raw material proportioning device for cement production, comprising a shell, a discharge pipe is connected to the bottom of the shell, a first solenoid valve is arranged on the discharge pipe, a raw material bin and at least one batching bin are arranged on the top of the shell, a second solenoid valve is arranged at the bottom of the raw material bin, a third solenoid valve is arranged at the bottom of each batching bin, a pair of guide rails are horizontally arranged in the shell, a first cylinder is slidably arranged on the pair of guide rails, a limit ring is arranged on the inner wall of the first cylinder near the bottom, A weight sensor is arranged on the limit ring, a second cylinder is arranged on the weight sensor, a fourth solenoid valve is arranged on the second cylinder, an electric telescopic rod is arranged on the inner wall of the shell and between a pair of guide rails, the telescopic end of the electric telescopic rod is connected to the outer wall of the first cylinder, a plurality of fixed rods are arranged on the inner wall of the shell and below the first cylinder, a material guide is arranged on the plurality of fixed rods, a motor is arranged inside the material guide, a rotating shaft is connected to the output end of the motor, the rotating shaft passes through the bottom of the material guide, and a plurality of stirring rods are arranged on the rotating shaft.

[0007] Preferably, the material guiding member is a rhombus-shaped body with a hollow structure.

[0008] Preferably, a material guide plate is provided near the bottom of the shell.

[0009] The utility model provides a raw material proportioning device for cement production, which has the following beneficial effects:

[0010] 1. The utility model adjusts the position of the first cylinder through the electric telescopic rod, so that the cement raw materials or ingredients can fall into the second cylinder. The weight sensor arranged on the limit ring weighs the materials in the second cylinder, so that the cement raw materials and ingredients can reach the specified ratio when mixed, thereby improving the accuracy of the ratio and ensuring the quality of cement production;

[0017] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0018] In the utility model, the first solenoid valve 1-2, the second solenoid valve 2-1, the third solenoid valve 3-1, the fourth solenoid valve 7-1, the motor 11, the weight sensor 6 and the electric telescopic rod 8 are all connected to the external electric control system through wires, wherein the weight sensor 6 can transmit a signal to the electric control system according to the weight it senses, thereby controlling the second solenoid valve 2-1 and the third solenoid valve 3-1. The above equipment and connection methods are all existing technologies and will not be described in detail here.

[0019] According to the instruction manual Figure 1-2 It can be known that when the utility model is in use, first the first solenoid valve 1-2 on the discharge pipe 1-1 is closed, and then cement raw materials and ingredients are added to the raw material bin 2 and the batching bin 3 respectively, and then the electric telescopic rod 8 arranged on the inner wall of the shell 1 is started, and the telescopic end of the electric telescopic rod 8 drives the connected first cylinder 5 to slide on a pair of guide rails 4, and a pair of sliders are arranged on the first cylinder 5, and the pair of sliders slide on a pair of guide rails 4, and the first cylinder 5 is moved to the lower part of the discharge port of the raw material bin 2 by the electric telescopic rod 8, and the second solenoid valve 2-1 is opened, and the cement raw materials fall from the raw material bin 2 into the second cylinder 7, and a weight sensor 6 is arranged on the limit ring 5-1 on the inner wall of the first cylinder 5, and the weight of the second cylinder 7 is weighed by the weight sensor 6. When the specified weight is reached, the second solenoid valve 2-1 is closed, and the fourth solenoid valve 7-1 on the second cylinder 7 is opened, and the overweight raw materials fall downward from the second cylinder 7 and fall into the bottom of the shell 1 after being guided by the material guide 10.
