Abstract

The utility model discloses an additive metering anti-overflow device of a concrete mixing plant, which comprises an additive metering barrel and a water metering tank, wherein the anti-overflow device is arranged between the additive metering barrel and the water metering tank and is used for distributing and conveying additives to the water metering tank or an external recovery tank according to needs.

Description

Concrete mixing plant admixture measurement anti-overflow flows device

Technical Field

The utility model belongs to the technical field of concrete mixing plants, and particularly relates to an admixture metering anti-overflow device of a concrete mixing plant.

Background

In the concrete mixing plant, the additive needs to be added and mixed after being metered in the concrete production process so as to improve the quality of the concrete or improve the performance of the concrete. In the conventional additive metering method, an additive is metered in an additive metering barrel and then enters a water metering tank to be mixed with water, and the mixture is put into a stirrer to be stirred with reference to fig. 1. The mode can completely meet and meet the production requirement in normal production. However, when special conditions occur, for example, errors result in more additive amount or damage to the valve and leakage of the additive, more additive can flow into water, and operators cannot find the additive in time, so that unqualified concrete is sent to construction sites for construction, and the whole or part of projects are scrapped.

SUMMERY OF THE UTILITY MODEL

The utility model aims to improve the defects of the prior art and provide an admixture metering anti-overflow device for a concrete mixing plant, which can prevent material leakage, avoid the complete or partial rejection of concrete, reduce economic loss and improve the quality of mixing equipment.

The utility model aims to realize the anti-overflow device for the additive metering of the concrete mixing plant, which comprises an additive metering barrel and a water metering tank and is characterized in that the anti-overflow device is arranged between the additive metering barrel and the water metering tank and is used for distributing and conveying additives to the water metering tank or an external recovery tank according to requirements.

In order to further achieve the purpose of the utility model, the anti-overflow device may include a swing box, a bearing seat, a swing arm, an air cylinder, a rotating shaft and a partition plate, two ends of the rotating shaft fixed on the swing box are mounted on an external frame through the bearing seat, one end of the swing arm is fixed on the rotating shaft, the other end is hinged to a piston rod of the air cylinder, the other end of the air cylinder is mounted on the external frame, a space in the swing box is divided into an adding cavity and an overflow cavity by the partition plate, and the bottoms of the adding cavity and the overflow cavity are respectively provided with an outlet.

In order to further achieve the purpose of the utility model, the partition board can be triangular, and the top openings of the adding cavity and the overflow cavity are formed to be larger than the lower outlet state.

Compared with the prior art, the utility model has the following remarkable characteristics and positive effects: according to the utility model, the anti-overflow device is additionally arranged between the additive metering barrel and the water metering box and is used for distributing and conveying additives to the water metering box or the external recovery box according to needs, namely when additives need to be added in normal production, the additives in the additive metering barrel are conveyed to the water metering box, after the additives are added according to needs, the box body of the overflow device swings to cut off the conveying passages of the additive metering barrel and the water metering box while the adding valve is normally closed, so that the problem that the concrete is unqualified due to leakage of the additives into the water metering box caused by some reasons is avoided, and meanwhile, the overflowed additives are recycled and reused, so that the waste is reduced; the overflow device consists of a swing box body, a bearing seat, a swing arm, an air cylinder and a rotating shaft, wherein the swing box body can swing, the swing box body is provided with two outlets, the swing box body is driven to swing through the expansion and contraction of the air cylinder, when the additive needs to be added, an inlet of an adding cavity is aligned to an outlet of an additive metering barrel, an outlet of the adding cavity is aligned to an inlet of a water metering box, so that the additive smoothly enters the water metering box, when the additive does not need to be added, an inlet of an overflow cavity is aligned to an outlet of the additive metering barrel, and an outlet of the overflow cavity is aligned to an external recycling box, so that the leaked additive flows into the external recycling box for recycling; the baffle is triangular, so that the top openings of the adding cavity and the overflow cavity are larger than the lower outlet, and additive leakage caused by the fact that the inlet is not aligned is avoided.
