Abstract
The utility model discloses a POY network yarn air pressure device, which comprises an air duct, a blower is arranged on the rear side of the air duct and electrically connected with a frequency converter and a pressure sensor is arranged inside the air duct. The blower can replace the compressor in the prior art to be used as air pressure power, and the rotation rate of the blower can be regulated through the frequency converter, so as to obtain stable air pressure. The device can generate air pressure by using the blower instead of the compressor in the prior art, so as to save equipment cost; and the omission of the compressor saves manpower cost and dispenses with the routine operation and maintenance of the compressor by an assigned staff, and the stable air pressure can be obtained through the variable frequency control of the blower. The device adopts the DCS system control, so that the air pressure control is more stable and the quality of POY network is ensured. Meanwhile, the DCS system can monitor the air pressure in the whole process and has a history inquiry function which is helpful for diagnosis of some product problems.
Description
Technical field
The utility model relates to the blast device in a kind of chemical fibre field, especially a kind of POY network yarn blast device.
Background technology
At present, in the device of China's melt Direct Spinning, POY network yarn blast control system all is to adopt compressor to produce compressed air, and further controls the requirement that compressed-air actuated pressure is realized POY network yarn blast.But, often because the complex structure of compressor, machinery and electrical system are had relatively high expectations, the incidence of various faults is also higher relatively, make to use and maintenance cost high always, in case and compressor break down, understand the production that directly influence the POY network yarn, the lighter influences quality, weight person's stopping production of being forced.And the parking of fused mass directly spinning device tends to influence the shakiness of its preceding road production of polyester line, therefore, causes very big loss sometimes.
Summary of the invention
The purpose of this utility model is that provide for the deficiency that solves above-mentioned technology a kind of provides blast, blast to stablize the POY network yarn blast device of being convenient to safeguard with blower fan.
In order to achieve the above object, the POY network yarn blast device that the utility model is designed, it comprises the air channel, described air channel rear side is provided with blower fan, blower fan is electrically connected with frequency converter, is provided with pressure sensor in the air channel, like this can be by blower fan replacement compressor in the past as blast power, and can realize the rotational speed regulation of blower fan by frequency converter, thereby obtain stable blast.For the control that makes blast more steady, described pressure sensor and frequency converter can be electrically connected with the DCS system, pressure sensor provides air channel internal pressure signal for the DCS system, the control of conversion device work of DCS system, the DCS system can change according to the detected air channel of pressure sensor internal pressure, the control of conversion device is regulated rotation speed of fan, thereby obtains a stable blast.Described blower fan is preferably roots blower, roots blower than common blower fan have energy-efficient, precision is high, noise is low, characteristics such as flexible for installation, and fan performance is sustained, can turn round continuously for a long time.
The resulting POY network yarn of the utility model blast device, blast can be produced by blower fan, replace the compressor of use in the past, save equipment cost, abandoning of compressor also saved human cost simultaneously, do not need to establish specially the people compressor is carried out regular job and maintaining, can obtain stable blast by variable frequency control to blower fan.Because used the control of DCS system, the control of blast is more steady, the quality of the POY network of assurance.Simultaneously, the DCS system can carry out complete monitoring to blast, and the historical query function is arranged, and the diagnosis of some problems of product is had positive meaning.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Among the figure: air channel 1, blower fan 2, frequency converter 3, pressure sensor 4, DCS system 5, digital display meter 6.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the described POY network yarn of present embodiment blast device, it comprises air channel 1, air channel 1 rear side is provided with blower fan 2, and blower fan 2 is electrically connected with frequency converter 3, is provided with pressure sensor 4 in the air channel 1, wherein blower fan 2 is a roots blower, pressure sensor 4 and frequency converter 3 are electrically connected with DCS system 5, and pressure sensor 4 provides the air channel 1 internal pressure signal for DCS system 5,5 control of conversion devices, 3 work of DCS system.Pressure sensor 4 is measured air channel 1 internal pressure, and the current signal of output 4-20 milliampere is given DCS system 5 controllers, the output signal of the analog quantity output 4-20 milliampere of DCS system 5 controllers is as the input signal of frequency converter 3, thus a blast control loop that constitutes.
When using at ordinary times, as long as the blast requirement when producing, change the setting value at DCS system 5 control points according to the POY network yarn, just can carry out the control that roots blower 2 is exported blast quickly and easily.And DCS system 5 can carry out complete monitoring and historical query to blast, helps the investigation of some quality problems of product.
As shown in Figure 2, the described POY network yarn of present embodiment blast device is the DCS system that utilizes among the digital display meter 6 replacement embodiment 1 that are with the PID function, and simple in structure, cost is lower, can be used for control is required lower occasion.
