Problems solved by technology

[0003] In the current common tobacco leaf drying technology, the temperature and humidity in the curing room are displayed separately on the side of the curing room, and the tobacco-curing workers need to continuously inspect the temperature and humidity of each curing room, which increases the labor intensity of the workers and the temperature control process. Instability, and the circulating air volume in each time period in the barn is fixed, which not only wastes power energy, but also cannot adjust the air volume more gently according to the drying degree of the tobacco leaves, which may have a certain impact on the quality of the tobacco leaves

Embodiment 1

[0025] Example 1, please refer to figure 1 —4:

[0026] The baking workshop includes a cluster baking room 1, a support frame 101, a high-precision temperature probe 102, a frequency conversion fan 103, a high-precision temperature instrument 104, a control cabinet 2, a fan 201, a partition 202, an activated carbon fiber layer 203, an air outlet 204, and a machine room 3 and a display screen 301.

[0027] The inner bottom of the cluster barn 1 includes a support frame 101, and the support frame 101 and the cluster barn 1 are welded and fixed, and the two sides of the upper end of the support frame 101 are provided with high-precision temperature probes 102, and the inside of the cluster barn 1 A frequency conversion fan 103 is installed, and a high-precision temperature instrument 104 is inlaid on the outside of the cluster barn 1 .

[0028] The lower end of one side of the cluster barn 1 is connected to the control cabinet 2, and the inner bottom of the control cabinet 2 is...

Embodiment 2

[0031] Example 2, please refer to Figure 5 :

[0032] The system modules include frequency conversion control system, circulation fan frequency conversion system, circulation fan controller switching system, signal integration system, alarm system and RS485 communication technology.

[0033] Frequency conversion control system: using touch screen mode, its function is;

[0034] (1) Set the speed of the variable frequency fan at a certain temperature range;

[0035] (2) Select the control system where the circulating fan is located.

[0036] Circulation fan frequency conversion system: the temperature probe is placed near the probe of the automatic control instrument in the barn, and the probe transmits the temperature signal to the integrated control system in real time. After receiving the probe signal, the integrated control system transmits the control signal to the frequency converter according to the set speed In order to precisely control the speed of the circulating...

Embodiment 3

[0041] The specific analysis of project data is as follows:

[0042] Statistical table of power consumption for single oven baking with different treatments

[0043] deal with Power consumption (degrees) Unit price (yuan) Amount (yuan) deal with 294 0.8 235.2 Control (CK) 316 0.8 252.8

[0044] It can be seen from the "Statistical Table of Electricity Consumption for Single Oven Baking with Different Treatments" that the baking room using the frequency conversion control system saves 7% of electric energy compared with the conventional baking room, which can show that the use of the frequency conversion control system has energy-saving effects.

Abstract

The invention discloses a clustered curing barn circulating fan variable-frequency control system. The clustered curing barn circulating fan variable-frequency control system comprises a curing plantand a system module. In the clustered curing barn circulating fan variable-frequency control system, fans are located below a separating plate, the separating plate is in a mesh shape, and therefore when electric appliances such as a main control computer are placed on the separating plate, the fans can well play a role in dissipating the heat of the electric appliances in a control cabinet, the wind flows from bottom to top, and the heat can be more quickly discharged out of an air outlet which is formed in the upper portion. In addition, the interior moisture can be removed in a drying modeby the wind, an active carbon fiber layer can absorb the interior moisture, and therefore the interior of the control cabinet can achieve the effects of moisture resistance and heat dissipation.

Description

technical field [0001] The invention relates to the technical field of barns for aviation research and development, in particular to a frequency conversion control system for circulating fans in a cluster barn. Background technique [0002] The frequency conversion control system of the circulating fan in the curing barn realizes the automatic regulation of the rotating speed of the circulating fan in the barn according to the setting program, without manual control of the circulating fan, that is, the fan speed can be adjusted according to the state of the tobacco leaves in the barn. [0003] In the current common tobacco leaf drying technology, the temperature and humidity in the curing room are displayed separately on the side of the curing room, and the tobacco-curing workers need to continuously inspect the temperature and humidity of each curing room, which increases the labor intensity of the workers and the temperature control process. Instability, and the circulatin...
