A feeding device for mortar preparation

Abstract

The invention discloses a feeding device for mortar preparation, which belongs to the technical field of mortar production equipment. The main point of the technical scheme is a feeding device for mortar preparation, which includes a feeding bin, which is provided with a feeding port, and the feeding device also includes The receiving bin, the quantitative container and the upper separation container. The upper separation container is located above the quantitative container. The quantitative container is connected with a moving mechanism. The moving mechanism can drive the quantitative container and the upper separation container to move synchronously. The upper separation container is connected with a separation mechanism. The mechanism can drive the upper separation container to move relative to the quantitative container. There is a feeding port at the bottom of the receiving bin, and a vertical partition plate is fixedly connected in the receiving bin. The feeding port and the discharging port are respectively located on both sides of the partition board. , the quantitative container is connected with a discharge mechanism, through which the material in the quantitative container can be taken out. It achieves the effect of precise control of the input amount of additives and automatic input of additives.

Description

technical field [0001] The invention relates to the technical field of mortar production equipment, in particular to a feeding device for mortar preparation. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and bonding materials (cement, lime paste, clay, etc.) and water. [0003] For the mortar production line in the prior art, please refer to the Chinese patent whose authorized announcement number is CN104999565B, which discloses a high-precision dry-mixed mortar production line intelligent electrical control system, including powder distribution system, sand batching system, material weighing system, Mixing bin, dust collection system and finished product assembly system, powder distribution system includes powder bin and powder auger, sand distribution system includes dry sand warehouse and dry sand elevator, material weighing system includes powder scale, dry Sand feeding scale and sand ...

AI Technical Summary

Problems solved by technology

[0004] When batching mortar, most of the automatic feeding devices in the prior art are aimed at feeding tons of powder, but mortar needs to be added with different additives to improve its performance, but the mass ratio of additives is usually 0.1~1‰, domestic Trace additives in most dry-mixed mortar production lines (mainly referring to special additives such as cellulose ether, rubber powder, etc., with an amount between 300 and 5000 g) are mainly fed manually or automatically added on site. The manual feeding process In the process, manual pre-weighing is required. When feeding manually, it is necessary to manually open the cover of the collecting hopper in each mixing cycle, put the pre-weighed small package of additives into the mixer, and then close the cover of the collecting hopper. , but the above operations are time-consuming and labor-intensive; in addition, the additive automatic metering and feeding system configured in the off-site dry-mixed mortar production line is equipped with a weighing sensor and adopts a superposition metering method. The sensitivity of the sensor is as high as 1 / 12000, and its price It is more than ten times that of ordinary sensors. At the same time, the metering system has extremely high requirements on control components such as sensors and butterfly valves. This equipment is suitable for the additive metering range below 70kg, and its metering minimum resolution can reach 5g

[0005] However, the structure of the above-mentioned automatic metering and feeding system for additives is relatively complicated, the overall process requirements of the equipment are extremely high, and the cost is extremely expensive. For the trace additives used in the range of 300-5000g, the metering accuracy does not have a good advantage. Dry-mixed mortar The steel structure of the production line has vibrating screens, mixers and other equipment with great vibration interference, which will cause great interference to the sensor signals of the high-precision metering system, which may lead to inaccurate weighing and metering of additives
