Embodiment 1

[0088] Such as Figure 1 to Figure 18 As shown, a kind of aggregate precooling system of the present embodiment comprises:

[0089] Cold material building 1;

[0090] The pre-cooling part 2 is fixed on the cold material building 1 and includes several aggregate pre-cooling warehouses 9;

[0091] The material conveying part 3 includes a sliding part slidably arranged on the cold material building 1. After the sliding part slides and communicates with one of the aggregate pre-cooling bins 9, the aggregate is transported into the aggregate pre-cooling bin 9;

[0092] There are several discharging parts 4, and the discharging parts 4 and the aggregate pre-cooling bins 9 are provided in one-to-one correspondence.

[0093] Aggregate needs to be pre-cooled before use to reduce the calorific value of the concrete mixture. Most of the existing aggregate precooling uses a belt conveyor as the carrier, and the aggregate is precooled during the aggregate transmission process; the preco...

Embodiment 2

[0101] In this embodiment, on the basis of Embodiment 1, the structure and function of the precooling unit 2 will be described.

[0102] Such as Figure 1 to Figure 16 As shown, in the specific embodiment provided by the present disclosure, the aggregate pre-cooling bin 9 can be configured as any suitable structure. As an option, the aggregate pre-cooling bin 9 includes a bin body 91 and a pre-cooling assembly 92 located in the bin body 91;

[0103] The bin body 91 includes a pre-cooling bin 911;

[0104] Pre-cooling assembly 92 includes:

[0105] The partition 921 is located in the pre-cooling bin 911 and divides the pre-cooling bin 911 into a plurality of interconnected pre-cooling spaces. The partition 921 is opened and closed to allow the aggregate to pass from one pre-cooling space to another pre-cooling space;

[0106] The pre-cooling part 922 includes a spraying part located at one end of the pre-cooling bin 911 and a water collecting part at the other end of the pre...

Embodiment 3

[0189] as attached Figure 1-4 as well as Figure 17-18 As shown, this embodiment is based on Embodiments 1 and 2, and describes other parts that make up the aggregate precooling system of this invention.

[0190] In the specific implementation manner provided in the present disclosure, the delivery part 3 can be configured as any suitable structure. As an option, the delivery section 3 includes:

[0191] The material distribution component 31 is slidably arranged on the cold material building 1 and transports the aggregate to the aggregate pre-cooling warehouse 9;

[0192] The sand sending component 32 separates the aggregate and the sand, and transports the sand to the sand storage bin 5 .

[0193] Now supplement the structure of the material conveying part 3, wherein, the material distribution component 31 undertakes the aggregate and distributes the aggregate. Since there are multiple aggregate pre-cooling warehouses 9, in order to achieve a simplified structure, reduce...

Abstract

The invention provides an aggregate precooling system. The aggregate precooling system comprises a cooling building, a precooling part, a conveying part, a plurality of discharging parts. The precooling part is fixed on the cooling building and comprises a plurality of aggregate precooling bins. The conveying part comprises a sliding part slidably arranged on the cooling building, and after the sliding part slides and communicates with one aggregate precooling bin, aggregate is conveyed into the aggregate precooling bin. The discharging parts correspond to the aggregate precooling bins one toone. The problem that an existing aggregate precooling effect is poor is solved. According to the aggregate precooling system, through mutual cooperation of the conveying part, the precooling part andthe discharging parts, automatic aggregate precooling is achieved, the labor cost is reduced, the aggregate precooling efficiency is improved, the construction period is shortened, and the productioncost is reduced. The aggregate precooling bins increase the contact time and the contact area of aggregate and precooling liquid, the precooling effect is improved, part of the aggregate is graduallyimmersed by the precooling liquid along with continuous adding of the pre-cooling liquid, and the precooling effect is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of aggregate precooling, and in particular relates to an aggregate precooling system. Background technique [0002] Aggregate, also known as "aggregate", is a granular material that acts as a skeleton and filling in concrete and mortar. There are two types of fine aggregate and coarse aggregate. The diameter of fine aggregate particles is between 0.16 and 5mm. Generally, natural sand is used, such as river sand, sea sand and valley sand. When there is a lack of natural sand, hard rock grinding can also be used. Crushed artificial sand; the diameter of coarse aggregate particles is greater than 5mm. Commonly used are crushed stones and pebbles. Under the same conditions, the strength of crushed stone concrete is higher than that of pebble concrete, but crushed stones are made by crushing rocks, and the cost is relatively low. Pebbles are high. Coarse aggregates commonly used in lightweight aggregate concret...
