Description
Technical field
The utility model relates to a kind of storage silk room inside and outside differential pressure automatic balancing arrangement.
Background technology
At present, in the storage silk chamber of tobacco business, air-conditioning system does not have the technique exhaust system, and it is mainly a plurality of Temperature Humidity Sensors according to indoor location that storage silk room air-conditioning is controlled indoor temperature and humidity regulation, and indoor and outdoor pressure reduction is not as controlled condition.Usually during the Air-conditioner design design, the air supply motor power ratio return air power of motor of selecting is large, in running, often there will be the smooth phenomenon of return air simultaneously, causes in storage silk room air positive pressure excessive, can not meet the technological requirement of a storage room pressure-fired.Can cause like this greenhouse degree to control the adverse consequences such as difficulty strengthens, moisture in cut tobacco is difficult for guaranteeing, the energy consumption increase increases.
The utility model content
The utility model provides a kind of storage silk room inside and outside differential pressure automatic balancing arrangement, can realize pressure-fired in storage silk room, guarantees process requirements, reduces the energy consumption waste.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of storage silk room inside and outside differential pressure automatic balancing arrangement comprises signal gathering unit, CPU and performance element; Signal gathering unit comprises differential pressure pickup and the Temperature Humidity Sensor be arranged in storage silk room, and the signal output part of signal gathering unit is connected with the signal input part of CPU, and the CPU output connects performance element; Performance element comprises the frequency converter be connected with air supply motor and the new fan valve executor be connected with new air-valve.
The signal output part of CPU is connected with display unit.
Differential pressure pickup adopts the QBM66.201 differential pressure pickup.
The utility model storage silk room inside and outside differential pressure automatic balancing arrangement is by detecting signal unit, to detect in real time storage silk room inside and outside differential pressure signal to be sent to CPU, CPU is carried out comprehensive analysis processing according to storage silk room humiture model and differential pressure pickup signal, output adjusting air valve aperture and adjusting frequency converter speed-frequency voltage signal, regulate air-supply and return air amount size, make to keep pressure-fired in storage silk room, meet process requirements, reduce energy consumption.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of storage silk room inside and outside differential pressure automatic balancing arrangement, comprise signal gathering unit, CPU 3 and performance element; Signal gathering unit comprises differential pressure pickup 2 and the Temperature Humidity Sensor 9 be arranged in storage silk room 1, and the signal output part of signal gathering unit is connected with the signal input part of CPU 3, and CPU 3 outputs connect performance element; Performance element comprises the frequency converter 7 be connected with air supply motor 8 and the new fan valve executor 5 be connected with new air-valve 6.The signal output part of CPU 3 is connected with display unit 4.Differential pressure pickup 2 adopts the QBM66.201 differential pressure pickup.
The signal that differential pressure pickup 2 will collect sends to CPU 3, and CPU 3 is carried out analyzing and processing, and when differential pressure pickup 2 pressure reduction were greater than setting value, CPU 3 was sent instruction, regulates new fan valve executor 5 and turns down new air-valve 6 apertures; Regulate frequency converter 7 frequencies, reduce air supply motor 8 rotating speeds, reduce the air quantity of pressure fan, make differential pressure pickup 2 pressure reduction reach setting value, keep the indoor pressure-fired in storage silk room 1.CPU 2 also is presented at display unit 4 by pressure difference data.
