Description

Environment-friendly dry powder mortar stirring building based on storage bin top full-spread structure

Technical Field

The invention relates to a dry powder mortar mixing plant, in particular to an environment-friendly dry powder mortar mixing plant based on a storage bin top full-paved structure.

Background

A dry powder mortar mixing plant is a combined device for intensively mixing concrete, and is also called a concrete prefabricating field. Because the dry powder mortar mixing plant has higher mechanization and automation degree, the dry powder mortar mixing plant can ensure the quality of concrete and save cement, and is commonly used for large and medium-sized water conservancy, electric power, bridges and other projects with large concrete engineering quantity, long construction period and centralized construction sites. In order to improve stirring efficiency, the top-placed concrete mixing plant is designed in the prior art, the powder tank is arranged at the top of the support frame, so that the occupied area and the basic cost of the mixing plant are reduced, the weighing of sand and stone needs to be completed on the ground, the sand and stone are conveyed to the pre-feeding hopper through the adhesive tape machine, and are mixed and stirred with powder through the stirring machine, but the sand and stone cannot be supplied simultaneously due to the arrangement of the traditional mixing plant, the volume of the pre-feeding hopper is limited, and the high-speed mass production of concrete cannot be met.

In order to meet the requirement of high-speed mass production of concrete, a novel dry powder mortar mixing plant is disclosed by the application of a patent No. CN201721864817.9, a novel overhead concrete mixing plant is invented, a powder bin, an aggregate bin and a sand bin are all arranged on the upper part of the mixing plant, the storage amount of sand in the mixing plant is improved, the mass production of concrete can be met at one time, simultaneously, the foundation cost is reduced and the production efficiency is further improved as the stone bin and the sand bin are directly arranged on the top of a support frame, the concrete structure is as shown in the attached drawings 1 and 2, wherein the concrete mixing plant comprises a powder bin 103, an aggregate bin 104 and a sand bin 105, but the aggregate bin is arranged in the middle and the powder bin is arranged on the periphery, the aggregate bin and the powder bin are respectively and independently arranged, the support frames are provided, the aggregate bins are arranged on different platforms, and simultaneously, small powder bins and water tanks need to be independently arranged, the structure of the mixing plant is not compact, the space utilization rate is low, and the maintenance platform is relatively independent, so that the daily maintenance is not facilitated; in addition, the powder bin is a round storage bin, the aggregate bin and the sand bin are square storage bins, the number of structural types of the powder bin is large, the structure is not beneficial to generalization and standardization, and the manufacturing cost is high. In prior art and engineering application at present, the aggregate bin is usually set to be square, because in the production process, in the same packaging range, the volume of storage of square bin can be greater than circular bin, because the volume has greatly reduced the number of times of carrying and adding, for example CN201910079758.1 and the square bin that sets up with CN201721864817.9, and the square bin is all the independent support setting, that is, square aggregate bin and circular powder bin set up separately, thereby make the square bin volume not restricted by space, make the storage maximize, but the square bin also has following problem: in the construction engineering of the actual mixing plant, the square bin is of a split structure and needs to be spliced by bolts on site, so that the problems of high processing difficulty and long working time exist.

Simultaneously, because the environmental protection requirement is stricter day by day, in present concrete production, like CN201721864817.9 powder storehouse and aggregate storehouse setting of straying in vertical direction, this kind of setting can lead to the dust in the feed bin can fall to batching layer or stirring layer, leads to production operating mode dust to scatter everywhere, and production operating mode environment is relatively poor, collects the dust moreover and also can be difficult. In addition, correspond every feed bin of top in batching layer and be and set up a conveying structure, carry the material corresponding weighing structure in, because every stirring upstairs all contains a large amount of feed bins, consequently, too much too complicated at batching layer transport mechanism, be unfavorable for the arrangement and the installation of batching layer.

Disclosure of Invention

The invention aims to solve the problems of complex structure, low space utilization rate and the like of a mixing plant in the prior art, and provides an environment-friendly dry-mixed mortar mixing plant based on a storage bin top full-paved structure.

As a further improved technical scheme of the invention, the plurality of bins are uniformly arranged on the bin layer at the top of the integral combined frame, the circular bins with the same diameter are uniformly and fully arranged on the bin layer at the top of the integral combined frame, and only a minimum gap required for installation is left between all the bins. Since all the bins are disposed on the bin level on top of the integrated frame, there is a limit in storage space, and therefore, the use of the bin level can be maximized by fully laying the bins and leaving only a minimum gap between the bins required for installation.

As a further improved technical scheme of the invention, the heights of a plurality of bins are the same or similar; the aggregate bin top and the powder bin top are leveled into an integrated platform, so that a smooth space is formed, the maintenance and repair of equipment on the bin top are facilitated, and the control of dust is facilitated.

Furthermore, a plurality of small storage bins are arranged among the plurality of bins and are used for storing water, liquid additives or powdery additives.

Further, the bin legs are mounted on the top end of the integral frame.
