Description

Technical Field

[0001] This utility model relates to the field of textile dyeing and finishing technology, and in particular to an automatic steam control device. Background Technology

[0002] In industrial production processes such as textile dyeing and finishing, automatic steam control devices are often used to heat heating drums to dry fabrics. Temperature detectors, as key components of these devices, are used to monitor the temperature of the heating drums in real time to precisely adjust steam flow and ensure drying effectiveness. However, in practical applications, the ambient temperature of the temperature detectors is often high, which significantly impacts their detection accuracy. High temperatures can easily degrade the performance of the internal electronic components of the temperature detector, leading to data deviations, affecting the precise control of steam flow, and reducing the quality of fabric drying. Furthermore, prolonged exposure to high temperatures accelerates the aging of electronic components, greatly shortening the lifespan of the temperature detector, increasing equipment maintenance costs and downtime for repairs, and negatively impacting production continuity and efficiency. Therefore, effectively addressing the problems of low detection accuracy and short lifespan of temperature detectors in high-temperature environments has become a pressing technical challenge in this field. Utility Model Content

[0003] The purpose of this invention is to provide an automatic steam control device. The cooling fan can effectively cool the body of the temperature detector, thereby increasing its service life. The isolation plate can effectively reduce the impact of the cooling air on the detection end of the temperature detector, improving detection accuracy and thus enabling more precise steam control.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An automatic steam control device includes multiple sets of heating drums, a steam inlet pipe for supplying steam to the heating drums, a flow regulating valve and a temperature detector installed on the steam inlet pipe, the temperature detector being electrically connected to a controller, and the controller controlling the opening degree of the flow regulating valve; the temperature detector is positioned directly opposite one of the heating drums.

[0006] The temperature detector is equipped with a cooling fan at its rear.

[0007] The fabric to be dried passes sequentially through multiple sets of heating rollers. Steam inlet pipes heat the rollers, which in turn heat the fabric, thus completing the drying process. A temperature sensor monitors the temperature of the heating rollers and feeds the signal back to the controller in real time. If the temperature is too low, the steam flow rate is increased via a flow control valve, and vice versa. A cooling fan cools the temperature sensor's body, improving the working environment of its internal electronic components, increasing measurement accuracy, and extending the sensor's lifespan.

[0008] Furthermore, the detection end of the temperature detector is inserted into the middle of the isolation plate. By setting the isolation plate, the air blown out by the cooling fan can be prevented from entering the detection end of the temperature detector, thereby affecting the detection accuracy.

[0009] Furthermore, the outer end of the isolation plate is fixed with an outer cylinder extending towards the cooling fan, and the outer cylinder is fixed with an inner cylinder by a retainer. The cooling fan is fixed inside the inner cylinder; the outer cylinder is fixed on the frame of the dyeing and finishing equipment.

[0010] One end of the inner cylinder is positioned close to the isolation plate with a gap. A cooling fan draws outside air into the inner cylinder, which then blows it onto the temperature detector's body and the isolation plate, thus cooling the temperature detector. The air then flows out through the gap between the inner cylinder and the isolation plate into the outer cylinder, and is subsequently exhausted away from the heating drum through the outer cylinder. This reduces the impact of the temperature detector on the temperature readings of the heating drum.

[0011] Furthermore, the isolation plate is formed with a V-shaped air guide groove, which allows air entering from the inner cylinder to be easily guided into the outer cylinder and then discharged from the outer cylinder.

[0012] Furthermore, a rubber sleeve is provided between the temperature detector and the isolation plate, and the rubber sleeve is fixedly connected to the isolation plate. The rubber sleeve allows for more effective and convenient fixation of the temperature detector, and also facilitates the adjustment of the temperature detector's position.

[0013] Furthermore, the length of the inner cylinder is more than twice the length of the outer cylinder.

[0014] Furthermore, the outer cylinder is fixed to a support by multiple sector-shaped strips, and the inner cylinder is inserted into and fixed to the support;

[0015] The support has several small holes that communicate with the inner cylinder. These holes allow the airflow entering the inner cylinder to be filtered, thus ensuring the cleanliness of the inner cylinder and the external environment of the temperature detector.

[0016] The outstanding effect of this utility model is:

[0017] Compared with existing technologies, by installing a cooling fan at the tail of the temperature detector to cool it down, the working environment of its internal electronic components is improved, effectively reducing the impact of high temperature on detection accuracy. This allows the temperature detector to more accurately detect the temperature of the heating drum, thereby achieving precise control of steam flow and improving the quality of fabric drying.

[0018] The isolation plate prevents the air blown out by the cooling fan from affecting the detection end of the temperature detector, ensuring detection accuracy; the V-shaped air guide groove optimizes the airflow direction, allowing the cooling airflow to be discharged more smoothly; the rubber sleeve facilitates the fixing and position adjustment of the temperature detector; the design of small holes on the inner cylinder, outer cylinder and support ensures the cleanliness of the external environment of the temperature detector while achieving effective cooling, further improving the stability and reliability of equipment operation.

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] The following is for reference Figures 1 to 2 The present invention will be described as follows:

[0024] In practical applications, the automatic steam control device is first installed on the dyeing and finishing equipment, and the outer cylinder 7 is fixed on the frame of the dyeing and finishing equipment. The fabric to be dried passes through multiple sets of heating rollers 1 in sequence, and the steam inlet pipe 2 supplies steam to the heating rollers 1, which then heat and dry the fabric.

[0025] Temperature detector 4 is positioned directly opposite one of the heating drums 1, monitoring its temperature in real time and feeding the temperature signal back to the controller. Based on the received temperature signal, the controller adjusts the opening of the flow regulating valve 3. When the temperature is below the set value, the controller increases the steam flow through the flow regulating valve 3 on the steam inlet pipe 2; conversely, it decreases the flow, thus achieving automatic regulation of the steam flow.

[0026] The cooling fan 5 is fixed inside the inner cylinder 9. When the equipment is running, the cooling fan 5 starts, drawing outside air into the inner cylinder 9. The airflow blows towards the body of the temperature detector 4 and the isolation plate 6, cooling the temperature detector 4. Since the detection end of the temperature detector 4 is inserted into the middle of the isolation plate 6, the isolation plate 6 prevents the air blown out by the cooling fan 5 from entering the detection end of the temperature detector 4, thus avoiding affecting the detection accuracy.

[0027] One end of the inner cylinder 9 is close to the isolation plate 6 with a gap. The cooled airflow flows out to the outer cylinder 7 through the gap between the inner cylinder 9 and the isolation plate 6. The V-shaped air guide groove 10 on the isolation plate 6 conveniently guides the airflow into the outer cylinder 7, and then the air is discharged away from the heating drum 1 through the outer cylinder 7.

[0028] The rubber sleeve 11 between the temperature detector 4 and the isolation plate 6 ensures stable installation and convenient positioning of the temperature detector 4, while also facilitating adjustment of the installation position of the temperature detector 4 according to actual needs. The support 13, which is fixed to the outer cylinder 7 by the fan-shaped strip 12, has several small holes 14 that communicate with the inner cylinder 9. These holes filter the airflow entering the inner cylinder 9, ensuring the cleanliness of the inner cylinder 9 and the external environment of the temperature detector 4. This ensures that the temperature detector 4 operates in a good environment, improving detection accuracy and service life.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
