Description

Technical Field

[0001] The invention relates to the technical field of steam curing of prefabricated beams, and in particular to a water recycling device for steam curing of prefabricated beams. Background Art

[0002] Steam curing is to place concrete components in a closed steam curing room, pass hot and humid steam to raise the temperature of the concrete, accelerate the hydration and hardening process of cement and auxiliary cementitious materials, quickly reach the lifting strength (when it reaches 70% of the design strength), and speed up formwork turnover and production efficiency.

[0003] During the steam curing process, steam curing or spray curing is required continuously, which will generate a large amount of water. In the prior art, the water is directly discharged into the drain or recycled. First, in terms of water collection and filtration, the prior art has been able to effectively collect the wastewater generated during the steam curing process and remove impurities and particles in the water through various filtering methods. These filtering methods may include physical filtration, chemical treatment, etc., to ensure that the quality of the recycled water meets the standards for reuse.

[0004] Although the current technology has made some progress, there are still some challenges and problems. For example, there are still some problems in the configuration structure of the device for recycling water and the efficiency of water recycling. The specific manifestations are as follows: the current recycling water circulation device has incomplete collection of water. Only through some collection boxes to achieve water collection, some water will still overflow, and additional structures are required to treat this part of the water, and it is impossible to achieve comprehensive collection. This is mainly because the design of the collection device has defects, such as the limited capacity of the collection box, which cannot accommodate a large amount of wastewater; or the unreasonable layout of the collection box, resulting in some wastewater cannot flow in. This not only reduces the recycling rate of wastewater, but also may cause environmental pollution and waste of resources. The existing water treatment structure is generally built on the outside, and it needs to be guided by water pipes or ditches for filtering and treatment, which has the problem of large site occupation. The existing steam curing water recycling device often needs to set up a water treatment structure outside the steam curing shed, which requires a lot of site space. Moreover, since it is necessary to lay water pipes or ditches to guide the wastewater for filtering and treatment, the complexity and management difficulty of the site are further increased. This not only increases the equipment cost and maintenance cost, but also may affect the efficiency of prefabricated beam production. Although some people have tried to place the water collection structure in the steaming shed to achieve centralized equipment layout, the actual effect is not ideal. This is mainly because the existing steaming water recycling device is often composed of multiple independent components and lacks overall design and optimization. This leads to loose connections between the equipment, which is prone to water leakage, blockage and other problems, affecting the normal operation of the equipment.

[0005] Based on this, a large amount of condensed water and spray curing water will be generated during the steam curing process of precast beams. If these wastewaters are not treated and utilized, it will not only waste precious water resources, but also pollute the environment. Existing wastewater treatment devices often have problems such as incomplete collection and low treatment efficiency, which are difficult to meet the actual application needs. Therefore, it is necessary to study a precast beam steam curing water recycling device. Summary of the invention

[0006] In view of this, the object of the present invention is to provide a precast beam steaming water recycling device, which effectively solves the problems of incomplete collection of existing precast beam steaming water, complex equipment layout, difficulty in being built into the steaming shed, and the need to arrange the structure outside the steaming shed, affecting the layout of other equipment.

[0008] Furthermore, grooves are arranged at intervals in the collecting chamber, so that a plurality of low-water-level collecting troughs are formed in the collecting chamber, and a water pumping pipe is arranged in the collecting trough.

[0009] Furthermore, the water pumping pipe is a branch pipe, a filter head is arranged at the lower part, the upper part of each branch pipe is connected to the main pipe, and the main pipe is connected to the external pump, the steaming equipment and the steaming nozzle.

[0010] Furthermore, the filter layer has a structure with a larger lower portion and a smaller upper portion.

[0012] Furthermore, the moving assembly includes an upper moving wheel and a lower moving wheel, and the mounting frame is provided with an upper track and a lower track, and the upper moving wheel and the lower moving wheel are adapted to be nested in the upper track and the lower track.

[0013] Furthermore, the upper track and the lower track have the same structure, both are L-shaped tracks with an opening at the top, and their sides are fixed on the mounting frame. The upper moving wheels and the lower moving wheels both include a wheel frame, a transverse moving wheel and a vertical limiting wheel.

[0014] Furthermore, a connecting seat is provided on the upper portion of the scraper frame, and the connecting seat is fixed to the end of the shipping seat.

[0015] Furthermore, the upper moving wheel is an electric moving wheel.
