Description

Technical Field

[0001] The utility model relates to the technical field of supporting equipment for air jet looms, and more specifically to an independent air supply device applied to air jet looms. Background Art

[0002] Air jet looms need to be equipped with an air supply system to operate. Most of the current air jet looms use centralized air supply, that is, multiple air jet looms share a main pump station, which provides high-pressure air to each loom to achieve the weft insertion task of the air flow weft insertion mechanism of each loom. This requires the main pump station to be equipped with a high-power motor, and even when some looms are shut down and some looms are running, the main pump station is running at full speed, resulting in energy waste. Building a main pump station requires a large amount of capital investment, which increases production costs. Although some independent air supply systems for air jet looms are currently on the market, there are still defects such as unstable air supply and excessively high air supply temperature, which leads to high temperature in the loom workshop.

[0003] For example, patent application number CN202221522618.0 discloses an independent air supply device for an air jet loom, comprising a water-cooled air compressor driven by a main shaft of the air jet loom and an independent air bag, wherein the independent air bag is provided with a jacket on the upper surface, wherein a cylinder is provided in the jacket to separate it into an inner cooling cavity and an outer heat preservation cavity, and an air guide tube is spirally provided on the inner wall of the cylinder, wherein the inlet end of the air guide tube is connected to the air compressor, and the outlet end of the air guide tube extends into the independent air bag; an arc plate is provided at the bottom of the independent air bag, wherein a lower cooling cavity is formed between the arc plate and the bottom wall of the independent air bag, and the lower cooling cavity is connected to the outer heat preservation cavity through a connecting pipe I; an annular seat is provided at the top of the independent air bag, wherein an upper cooling cavity is provided in the side wall of the annular seat, and the inner cooling cavity is connected to the upper cooling cavity through a connecting pipe II, and the upper cooling cavity is connected to the outer heat preservation cavity through a connecting pipe III. The present invention has a simple structure and is easy to use.

[0004] The device guides the airflow by setting up an air duct inside the cylinder, and achieves heat exchange with the air duct through multiple sets of cooling chambers to reduce the airflow temperature. However, the temperature of the coolant inside the cooling chamber rises after the heat exchange, and the thermal conductivity effect decreases after long-term use. If there is a circulation function on the market, it needs to be turned on continuously, which consumes a lot of energy. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] See also Figures 1 to 4In the utility model, an independent air supply device for an air jet loom includes an independent air bag 1 and an air compressor 2. The air compressor 2 is located on the left side of the independent air bag 1. The top of the independent air bag 1 is fixedly connected with an air outlet pipe 3. The outer ring of the independent air bag 1 is integrally formed with an outward expansion interlayer 4. A cooling cavity 5 is opened inside the outward expansion interlayer 4. A temperature sensor 6 is fixedly installed on the inner wall of the cooling cavity 5. A heat-conducting coil 7 is fixedly connected to the inner wall of the cooling cavity 5. The top of the heat-conducting coil 7 passes through and extends to the inside of the independent air bag 1. The air pipe on the air compressor 2 is connected to the bottom end of the heat-conducting coil 7. The outer ring of the outward expansion interlayer 4 is fixedly connected with a circulation Box 8, the inner wall of the cooling chamber 5 is fixedly connected with a uniformly distributed return pipe 9, a solenoid valve 10 is installed on the return pipe 9, the other end of the return pipe 9 passes through the outer expansion interlayer 4 and extends to the inside of the circulation box 8, two refrigerators 11 are fixedly installed on the inner wall of the circulation box 8, two liquid pumps 12 are fixedly installed at the bottom of the circulation box 8, the top of the liquid pump 12 passes through and extends to the inside of the circulation box 8, the bottom of the liquid pump 12 passes through and extends to the inside of the cooling chamber 5 through a pipeline, a processor 13 is installed on the independent air bag 1, and the liquid pump 12, the solenoid valve 10, the temperature sensor 6 and the refrigerator 11 are all connected to the processor 13 signal;

[0023] A safety valve 14 and a pressure gauge 15 are fixedly installed on the top of the independent air bag 1, and the bottom ends of the pressure gauge 15 and the safety valve 14 both penetrate and extend into the interior of the independent air bag 1;

[0024] A timing module 18 is installed in the independent air bag 1 , and the timing module 18 is connected to the processor 13 by signal.

[0025] The air compressor 2 is driven by the main shaft of the air jet loom itself, saving electric energy, and sending the compressed air into the heat conducting coil 7 through the air pipe. At this time, the cooling chamber 5 is filled with coolant at a relatively low temperature. As the airflow is continuously filled into the heat conducting coil 7, the airflow begins to move upward, and the coolant can exchange heat with the airflow through the inner wall of the heat conducting coil 7, thereby reducing the temperature of the airflow. At this time, the heat of the coolant increases and the temperature begins to rise. When the airflow passes through the heat conducting coil 7 and enters the independent air bag 1, it will be discharged through the top air outlet pipe 3 to supply air to the air jet loom. The independent air bag 1 is also equivalent to a buffer air storage tank. Its existence ensures the stability of the air supply. At this time, the coolant in the cooling chamber 5 is heated and convection will occur. In this state, the coolant containing heat has a smaller density and thus rises and floats on the cold water, so that the temperature of the temperature sensor 6 arranged above begins to rise and transmits the value to the processor 13. When the value exceeds the set value, the processor 13 controls the solenoid valve 10 to be energized. After the solenoid valve 10 is energized, the coolant above the return pipe 9 begins to enter the circulation box 8 through the return pipe 9. The processor 13 cools the coolant entering the circulation box 8 through the refrigerator 11. After the time set by the timing module 18 is reached, the solenoid valve 10 is closed. At this time, the liquid level of the coolant is at the position of the return pipe 9. Subsequently, the liquid pump 12 is energized to generate pressure to send the refrigerated coolant into the cooling chamber 5, thereby forming a circulation use.

[0026] In the utility model, a cooling chamber 5 is provided in the independent air bag 1 and filled with coolant, so that the airflow generated by the air compressor 2 is transported through the heat-conducting coil 7. The coolant conducts heat and cools the heat-conducting coil 7, thereby reducing the temperature of the airflow entering the jet loom, thereby avoiding excessive supply temperature and causing excessive workshop temperature. A temperature sensor 6 is provided at the upper part of the cooling chamber 5 according to the convection principle to monitor the top water temperature. When the top water temperature is too high to dissipate heat, the coolant is introduced into the circulation box 8 for refrigeration and then sent into the cooling chamber 5 to achieve circulation, thereby ensuring the cooling effect of the coolant and reducing the energy consumption required for the circulation.

[0027] See also Figure 1 , wherein: evenly distributed heat sinks 16 are fixedly connected to the refrigerator 11 , and the heat sinks 16 penetrate and extend to the outside of the circulation box 8 .

[0028] In the present invention, the arrangement of the heat sink 16 can further improve the heat dissipation effect of the refrigerator 11 and increase the service life of the refrigerator 11 .

[0029] See also Figure 4 , wherein: a warning light 17 is installed on the independent air bag 1, and the warning light 17 is connected to the processor 13 by signal.

[0030] In the present invention, when the temperature value of the temperature sensor 6 exceeds the set value, the processor 13 will simultaneously control the prompt light 17 to be powered on, and the prompt light 17 starts to flash, so that the user can know the status of the device in time.
