Example Embodiment

[0055] Example 1

[0056] This Example 1 discloses a preparation apparatus for hydraulic cracking low shrinkage and high performance concrete, reference attached figure 1 Attach figure 2 The body member includes a bottom frame 1, a top end frame 2, a stirring mixing device 3, a bone material screening quantitative sheet device 4, a cement quantitative feed apparatus 5, auxiliary material 4, and a control cabinet 7. At one end of the top frame 2 on the upper surface of the bottom rack 1, the agitation mixing device 3 is fixed to the bottom frame 1.

[0057] Reference image 3 Attachment Figure 4 Attach Figure 5 The mixing mixing apparatus 3 includes a stirring mixing tank 301, a stirring motor 302 disposed at a center of the stirring mixing tank 301 and a discharge tube 303 attached to the lower end of the stirring mixing tank 301, disposed on the discharge tube 303. There is a slurrier valve 305. The inside of the stirring mixing tank 301 is provided with a stirring assembly 304, a...

Example Embodiment

[0062] Example 2

[0063] Example 2 discloses a preparation apparatus for improved hydraulic cracking low-shrinking high-performance concrete based on the first embodiment, which is not described again, and the difference is:

[0064] Please refer to image 3 Attachment Figure 5 The present embodiment 2 is also connected to the outer end of each end of the fork type plate 3043 and is vertically disposed and a wiper plate 3048 that is fitted to the inner wall of the stirring mixing tank 301. After completion of a batch of concrete, the continuous driving action of the stirring motor 302 causes the splitter plate 3048 to clean the mixing mixing tank 301, which can effectively prevent the inner wall of the stirring mixing tank 301, resulting in the preparation of subsequent concrete. Influence.

[0065] Reference Figure 8 The second embodiment is also provided with a vibrating motor 400 in the lower surface of the screening casing 408, and the vibration of the vibration motor 400 can ...

Abstract

The invention relates to the technical field of concrete, and particularly discloses a preparation process of hydraulic anti-crack low-shrinkage high-performance concrete and a preparation device. The preparation device comprises a bottom machine frame, a top end machine frame, a stirring and mixing device, an aggregate screening and quantitative discharging device, a cement quantitative feeding device, an auxiliary material quantitative feeding device and a control machine cabinet, the top end machine frame is arranged at one end of the upper surface of the bottom machine frame, and the stirring and mixing device is fixedly mounted on the bottom machine frame. The prepared concrete has the excellent characteristics of low shrinkage rate and high crack resistance, meanwhile, the concrete preparation device has the functions of screening fine aggregate and accurately weighing the fine aggregate, a redesigned stirring assembly can fully stir all components of the concrete, and the property of the prepared concrete is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of concrete, and specifically discloses a preparation process and a preparation device for hydraulic crack-resistant low-shrinkage high-performance concrete. Background technique [0002] In recent years, with the increasing investment in infrastructure construction of water conservancy projects, the commercial concrete currently on the market has high shrinkage and poor crack resistance. There is a difference between the actual ratio of the components and the theory; at the same time, the concrete is uneven during the mixing process, which makes the concrete vulnerable to the influence of the external environment during use, which leads to the expansion of concrete micro-cracks, and the intrusion of harmful substances causes concrete deterioration , reduce the durability of concrete and affect the service life of concrete structures. [0003] The invention patent with the application number of 202011067218...
