In daily life, some medicinal materials, acid and alkali component chemicals and other articles needing to be dried need to be used under the condition of being very dry. If the air is allowed to be dried naturally, the time and the labor are wasted; in order to rapidly dry medicines and the like, a machine set capable of achieving rapid drying is required in the market.
Disclosure of Invention
Aiming at the problems, the utility model provides the unit which has a simple structure and can effectively and quickly dry the articles to be dried.
In order to achieve the above purpose, the utility model adopts the following technical scheme that the centrifugal fan comprises a shell, an air inlet is arranged at the upper part of the shell, an air outlet is arranged at the bottom of the shell, a heater is arranged at the middle part in the shell, and a multi-wing centrifugal fan is arranged in the shell corresponding to the air outlet, and the centrifugal fan is characterized in that: be provided with oblique wind-guiding section and the vertical wind-guiding section of connecting heater and air intake in the shell, oblique wind-guiding section upper end is the swash plate, and the vertical board of vertical wind-guiding section links to each other with the swash plate lower extreme, vertical board and swash plate contained angle alpha are 135, the high-wide span ratio of vertical board and swash plate is for
As a preferable scheme of the present invention, the heater is a common fin heater, a stainless steel fin heater or a PTC ceramic heater.
The utility model has the beneficial effects that:
1. the utility model has reasonable structure, adopts upper air inlet and lower air return, effectively and quickly circulates hot air and indoor cold air which are stagnated in the drying chamber, and achieves the purposes of saving energy and improving the heat utilization rate.
2. The utility model has reasonable internal structure, the generated air quantity can be effectively ejected under the action of the inclined air guide section and the vertical air guide section, the range is wide, and the air speed is high.
3. The utility model adopts a reasonable flow guide structure, and because the temperature of the drying chamber is extremely high, the common motor can not adapt to the high-temperature environment and is easy to damage; the multi-wing centrifugal fan is matched with the air guide structure, so that air flow can flow rapidly, the heat of the fan is taken away, and the motor is relatively not in a high-temperature environment; the service life of the motor is prolonged.
4. The utility model is vertically installed and placed on the ground, and has simple structure and good appearance effect.

Detailed Description
The utility model includes the outer casing 1, the upper portion of the outer casing 1 is an air intake 3, the bottom of the outer casing 1 is an air outlet 8, the middle part in the outer casing 1 has heaters 7, there are multiple-wing centrifugal fans 9 corresponding to air outlet 8 in the outer casing 1, characterized by that: be provided with oblique wind-guiding section 4 and vertical wind-guiding section 5 of connecting heater 7 and air intake 3 in the shell 1, 4 upper ends of oblique wind-guiding section are swash plate 2, and vertical board 6 of vertical wind-guiding section 5 links to each other with 2 lower extremes of swash plate, vertical board 6 and 2 contained angles alpha of swash plate are 135, the height-width span ratio of vertical board 6 and swash plate 2 is for
In a preferred embodiment of the present invention, the heater 7 is a common fin heater 7, a stainless steel fin heater 7, or a PTC ceramic heater 7.
An inclined air guide section 4 and a vertical air guide section 5 are arranged in a shell 1 of the utility model, and a special air guide structure is not arranged in a conventional heating unit; the structure design of the utility model is based on the fluid mechanics principle, a three-dimensional model of the guide plate is established in three-dimensional modeling software SolidWorks according to a fan profile, a calculation domain is reasonably set in numerical simulation software Fluent by utilizing the fluid mechanics basic principle and relevant knowledge of computational fluid mechanics, a targeted grid division method is provided according to the characteristics of a research object and on the basis of laboratory hardware, wind load coefficients at different angles are calculated by a computational fluid mechanics numerical simulation method after calculating the boundary conditions selected to be added and a fluid dynamics Johnson-cook equation, and the wind load coefficients are contrasted and analyzed with the wind load coefficients estimated by an Isherwood empirical formula. Compared with the common drying equipment, the range can be effectively improved, the air pressure is improved, the damage to the motor due to overhigh temperature is prevented, and the service life of the motor is prolonged.
N represents the mass of combustion air, eta represents molar mass according to the mass conservation law, and a continuous equation of an Eulerian method can be deduced; according to the momentum theorem, when N is 100 and eta is 0.98, the optimal value can be obtained by deducing an Eulerian momentum equation calculation formula to obtain the included angle alpha of the air duct plate of the air outlet 8 which is 135 DEG and the high-width span ratio
Through above computational formula, adopt this kind of air-out form, device, multi-wing formula centrifugal fan and water conservancy diversion structure cooperation generate heat, have done two sets of contrast tests altogether, and first group is experimental: under the condition that the common drying unit and the drying unit with the optimized structure are both 10kw, after the machine is started for 10min, the temperature difference of the inlet air and the outlet air of the common drying unit is 48 ℃, and the temperature difference of the inlet air and the outlet air of the drying unit is 67 ℃.
The second set of tests: under the condition that the power of the common drying unit and the drying unit of the utility model is variable, when the temperature difference of the inlet air and the outlet air of the common drying unit reaches 50 ℃, the heating power is 11kw, and when the temperature difference of the inlet air and the outlet air of the drying unit with the optimized structure reaches 50 ℃, the heating power is 7.8kw, thereby obtaining the following conclusion: 1. the heating capacity of the drying unit is far greater than that of a common drying unit; 2. the energy-saving effect of the drying unit is 30% compared with that of the common drying unit, and the drying time is greatly shortened.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the utility model.
