Description

Modularized air supply device and working method Technical Field The invention belongs to the technical field of air supply devices, and particularly relates to a modularized air supply device and a working method thereof. Background In the field of industrial production and storage, the process of air-drying fermentation, precise assembly, clean production and the like of meat products has strict requirements on uniformity of ambient temperature and humidity and air flow speed, for example, in a meat product air-drying fermentation workshop, ham, sausage and other materials need to be placed on a trolley in multiple layers, the temperature and humidity and the water loss rate of the upper layer and the lower layer of the trolley are required to be kept consistent, otherwise, the quality of the materials is uneven, dust accumulation caused by local air flow dead angles needs to be avoided in the precise assembly workshop, indoor positive pressure needs to be maintained in a clean workshop to prevent external pollutants from entering, and the air supply range of a large storage warehouse needs to be flexibly adjusted according to the change of a cargo stacking area. In order to meet the environmental control requirements of the process, a centralized air conditioner air pipe air supply system is generally adopted in industrial scenes to realize ventilation and temperature and humidity regulation of a space, the core design of the traditional system is centralized air treatment and complex air pipe network distribution, specifically, air is uniformly treated by a large air conditioner unit, the treated air is conveyed to each area of a workshop through a complex air pipe network consisting of a main pipe, a branch pipe, a diffuser, a manual air valve and the like, and the air flow organization mode is usually a ceiling air supply mode, an upper-lower return mode or an upper-lower-side return mode of air return at the lower part of a ground/side wall. The existing centralized air conditioner air pipe air supply system is required to distribute air quantity through a complex main pipe and branch pipe network, and the length, pipe diameter and trend of an air pipe are required to be custom designed and constructed according to workshop layout; the shell, the fan and the air valve of the simple single air supply device are distributed components, an additional customized mounting bracket and a fixed structure are needed on site, a standardized hoisting accessory is not needed, the suspended ceiling can not be quickly mounted, the construction period is long, and the problems of overlarge air quantity in a near host area and insufficient air quantity in a far host area are easily caused by different air pipe paths and local resistance in the traditional system, and the accurate dynamic air quantity distribution can not be realized though the manual air valve is used for adjusting; the air quantity of the whole system is uniformly controlled by a single fan, the different real-time air supply requirements of different trolley areas in a meat product workshop and different production stations in a clean workshop cannot be met, for example, in a ham thawing workshop, the temperature difference between the centers of the uppermost layer and the lowermost layer of materials of a trolley is 2 ℃ due to traditional air supply, thawing quality is directly affected, the air quantity of an air outlet of traditional air supply equipment is distributed into a fixed mode, sufficient air quantity exchange can be obtained at a process point on a main runner, the environment is slowly updated at a process point in an air flow shadow area, and the inherent non-uniformity can directly lead to uneven material quality and affected part assembly precision in the scenes of multi-layer trolley of a meat product air drying fermentation workshop, the periphery of a workbench of a precise assembly workshop and the like.
