Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a precise batching device. Background Art

[0002] At present, the construction industry generally uses cement, sand, gravel, admixtures and water to mix into concrete for construction. The building is a reinforced concrete frame structure, and the wall materials are mainly hollow bricks, clay bricks and concrete blocks. Most of the existing concrete materials are based on cement. Cement is directly used as a bonding material. Cement accounts for a large proportion and has a high cost. Fly ash, aeolian sand and sand are used as admixtures, and then foaming agents are added to mix and maintain to form concrete. Cement production consumes a large amount of coal resources and releases a large amount of carbon dioxide greenhouse gas. Over time, it causes resource shortages and aggravates the greenhouse effect, causing environmental pollution. In addition, the compression resistance of the formed concrete needs to be strengthened.

[0003] As an advanced building material, high-strength concrete has been used more and more widely in recent years. The manufacturing process of high-strength concrete is also more advanced than that of traditional concrete, which enables better control of the quality and performance of concrete. At the same time, high-strength concrete is also excellent in energy saving and emission reduction, which can reduce the impact of buildings on the environment and achieve the goal of green buildings.

[0004] In order to solve the problems of high cement admixture cost and low batching efficiency, we designed a precise batching system, studied the mix ratio and composition of low-cement high-strength concrete, improved the batching efficiency and concrete strength, and reduced the input cost.

[0005] In the process of high-strength concrete batching, the system automatically discharges the materials according to the determined proportion. However, when the automatic discharge structure is damaged or blocked, the personnel often fail to find out in time, resulting in the failure of timely warning when there are errors in batching, and the product quality cannot be guaranteed.

[0006] To this end, we propose a precise batching device to solve the existing problems. Utility Model Content

[0007] The purpose of the utility model is to propose a precise batching device in view of the problems existing in the background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precise batching device, comprising a chamber, a wheel chamber, a hopper, a base and a working panel, the wheel chamber is installed at the bottom opening of the hopper, an impeller is rotatably installed inside the wheel chamber, a bent pipe is installed at the bottom opening of the wheel chamber, the other end of the bent pipe is embedded in the interior of the chamber, and a working panel is obliquely provided in the chamber.

[0009] Preferably, a cover is installed at the top opening of the hopper, and a feed pipe is installed at the center of the cover;

[0010] The outer surfaces of the hopper and the chamber are both equipped with fixing rods, and the other ends of the fixing rods are fixed on the base.

[0011] Preferably, a cushion is fixed to the outer surface of the chamber by bolts;

[0012] An audible and visual alarm is installed on the upper surface of the cushion seat by means of bolts, and the audible and visual alarm is electrically connected to the pressure sensor.

[0013] Preferably, the outer surface of the wheel cavity is mounted with a chassis by bolts;

[0014] A motor is fixed inside the chassis by bolts, and the output end of the motor is connected to the shaft end of the impeller.

[0015] Preferably, the bottom end of the inner wall of the chamber is designed to be an inclined surface, a pressure sensor is embedded and fixed on the inclined surface, and the working end of the pressure sensor is fixed on the working panel;

[0016] The position of the working panel corresponds to the position of the bent pipe;

[0017] A discharge port is provided at the bottom end of the chamber.

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

[0019] During use, the precise batching device of the utility model is connected to the external pumping pipeline through the feed pipe, and when the proportioned material enters the hopper and falls into the wheel cavity, the impeller in the wheel cavity is controlled to rotate at a uniform speed, so that the material in the wheel cavity can be evenly and equally delivered to the curved pipe. By controlling the rotation speed of the impeller, the batching amount can be controlled;

[0020] When the material falls into the chamber, it falls onto the working panel in a parabola under the action of the bend pipe, and the force is detected by the pressure sensor through the working panel. When the material is normally batched and falls, the force exerted on the pressure sensor is in a stable range. When an excessive or small amount of material enters the chamber, the force exerted on the pressure sensor is not in the stable range, and the sound and light alarm is controlled to sound an alarm.

[0021] The utility model can monitor the material flow in the batching process in real time, and give early warning for the situation of large batching error, so as to adjust the batching in time and improve the system efficiency and product quality. BRIEF DESCRIPTION OF THE DRAWINGS
