Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to a spinning cooling air conveying device. Background Technology

[0002] In polyester fiber spinning production, the cooling air system needs to provide stable process air with stable temperature, pressure, and humidity for the fiber bundle, and its performance directly affects the fiber quality.

[0003] Traditional spinning cooling air conveying devices generally adopt a transmission structure of "motor + V-belt + fan". The motor drives the fan to rotate via a 3-4 meter long V-belt to generate airflow, and cooling is achieved by the motor's built-in fan. For example, patent CN214742169U discloses a belt-driven industrial fan, including a mounting base, a fan body mounted on the mounting base, an upward-opening air outlet on the fan body, a drive shaft bracket on the fan body, a transmission mechanism above the drive shaft bracket, a belt mounted on the transmission mechanism, and a motor for driving the fan mounted on the mounting base. The transmission mechanism is connected to the motor via a belt, and the fan body and the motor are fixed to the mounting base with fixing bolts. This modular design allows the product to be disassembled for transport through narrow entrances and facilitates maintenance. The use of pulleys and a transmission disc allows for motor speed control and fan speed adjustment.

[0004] However, the above design has significant drawbacks. First, belt drives are prone to slippage due to their long length, easily weakened tension, and oxidation over time. This leads to reduced motor efficiency, fluctuations in air pressure, uneven cooling of the fiber bundle, and quality issues such as loose loops, broken ends, or fiber fineness deviations. Second, traditional belt drive structures for motors occupy a large space, requiring significant additional factory space for large-scale production, increasing infrastructure and energy costs (the motor needs to rotate 1.4 revolutions to drive the fan once). Furthermore, belts, being wear parts, require inspection every 3-6 months and replacement approximately every 2 years. Slippage exacerbates shaft wear, leading to increased equipment vibration, shortened lifespan of bearings and other components, increased downtime for maintenance, and severely impacting production continuity.

[0005] The aforementioned problems have hampered the stability of the spinning process and the efficiency of the equipment, necessitating technological breakthroughs through structural innovation. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art and to provide a spinning cooling air conveying device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A spinning cooling air conveying device includes a combined cooling system and multiple pairs of motors and fans located within the combined cooling system. In the same pair of motors and fans, the output shaft of the motor is connected to the input shaft of the fan via a coupling. The motor and fan are directly connected via the coupling, so as to realize coaxial transmission between the output shaft of the motor and the input shaft of the fan.

[0009] As a preferred technical solution:

[0010] As described above, a spinning cooling air conveying device includes a combined cooling system with a first rectifier baffle, a second rectifier baffle, a primary filter, and a surface cooler arranged vertically, parallel to the front and rear direction, with their edges attached to the inner wall of the combined cooling system and spaced from left to right.

[0011] The first rectifier baffle is provided with a first return air passage, the second rectifier baffle is provided with a second return air passage, and a mixing valve is installed on the second return air passage.

[0012] The part located to the left of the first rectifier baffle in the combined cooling system is the return air chamber. The return air chamber is equipped with a return air valve and a pair of motors and fans are installed inside the return air chamber. The air outlet of the fan is connected to the first return air vent.

[0013] The section between the first and second rectifier baffles in the combined cooling system is the flow stabilization chamber, and an exhaust valve is installed on the flow stabilization chamber;

[0014] The section between the second rectifier baffle and the primary filter in the combined cooling system is the fresh air chamber. The fresh air chamber is equipped with a fresh air valve, a pair of motors and a fan, and the air outlet of the fan faces the primary filter. The mixing valve is used to control the amount of return air entering the fresh air chamber, and the exhaust valve is used to exhaust excess return air. The motor in the fresh air chamber drives the fan to introduce fresh air, which mixes with the return air regulated by the mixing valve in the fresh air chamber.

[0015] The surface cooler has internal heat sinks that exchange heat with the airflow (cooling or heating) to bring the airflow to the required process temperature.

[0016] As described above, a spinning cooling air conveying device includes a spray device located between the primary filter and the surface cooler in the combined cooling system. The spray device comprises multiple vertically arranged spray pipes, which allow for uniform distribution of water pressure to the spray area. A ventilation baffle plate is also located between the spray pipes and the surface cooler in the combined cooling system. This baffle plate is vertically arranged, parallel to the front-to-back direction, and its edges are attached to the inner wall of the combined cooling system. The ventilation baffle plate consists of multiple vertically arranged plates, with adjacent plates staggered vertically to form an S-shaped airflow channel. Airflow can pass through the channel to the right, while water droplets generated by the spray adhere to the plate surface due to inertia and flow down the plate back to the water tank, thus achieving air-water separation.

[0017] As described above, in the combined cooling system, a vertically arranged air distribution plate is provided in the part between the primary filter and the spray pipe, which is parallel to the front and back direction and whose edge is attached to the inner wall of the combined cooling system. The air distribution plate is used to evenly distribute the airflow. The air distribution plate and the ventilation baffle plate are maintained at a distance of 20-30mm by spacers to form a uniform airflow channel.

[0018] As described above, the spinning cooling air conveying device further includes a water tank, a first water pipe, a water pump, and a second water pipe; the lower end of the spray pipe is located inside or directly above the water tank, the water tank is connected to the inlet of the water pump through the first water pipe, the outlet of the water pump is connected to the second water pipe, and the second water pipe is connected to the upper end of the spray pipe.

[0019] As described above, in a spinning cooling air conveying device, the part located on the right side of the surface cooler in the combined cooling system is divided into a first process air chamber, an environmental air chamber, and a second process air chamber arranged sequentially from top to bottom by two horizontally arranged partitions.

[0020] The first process air chamber, the environmental air chamber, and the second process air chamber are respectively provided with a first process air outlet, an environmental air outlet, and a second process air outlet on their right walls.

[0021] Each of the first process air chamber, the environmental air chamber, and the second process air chamber is equipped with a pair of motors and fans. Each chamber also features vertically arranged, parallel to the front-to-back direction, with edges flush against the inner walls and partitions of the combined cooling system, and spaced from left to right with medium-efficiency and high-efficiency filters. The fan outlets face the medium-efficiency filters. The motors and fans in the first and second process air chambers are designed for different production lines and can independently adjust their airflow frequency to match production needs. The motor and fan in the environmental air chamber are located in the middle and can be temporarily switched to a backup airflow mode in case of a production line fan failure, ensuring production continuity. The treated airflow is then fed through the fan section into the medium-efficiency and high-efficiency filters, ultimately achieving clean air supply standards.

[0022] As described above, the fans in the first process air chamber, the environmental air chamber, and the second process air chamber do not contain fans. The surface cooler in the combined cooling system controls the hot / cold water flow through the regulating valve to keep the temperature of the fan chamber within a low range. The low-temperature airflow passes through the motor casing to achieve passive cooling, eliminating the need for traditional motor fans, simplifying the equipment structure while improving heat dissipation efficiency.

[0023] As described above, the spinning cooling air conveying device uses glass fiber for the primary filter, the medium-efficiency filter needle, and the high-efficiency filter. The primary filter has a filtration accuracy of ≥80% for particles with a diameter ≥5μm; the medium-efficiency filter has a filtration accuracy of ≥90% for particles with a diameter ≥3μm; and the high-efficiency filter has a filtration accuracy of ≥99% for particles with a diameter ≥1μm.

[0024] Beneficial effects:

[0025] (1) This utility model directly connects the motor and the fan through a coupling, realizing coaxial transmission between the motor output shaft and the fan input shaft. The transmission ratio is 1:1 (when the motor rotates 1 revolution, the fan also rotates 1 revolution), eliminating the speed loss of traditional belt drive, avoiding wind pressure fluctuations caused by belt slippage, eliminating the need to reserve belt running space, making equipment installation and maintenance more convenient, and greatly reducing downtime losses and parts replacement costs.

[0026] (2) The fans in the first process air chamber, the environmental air chamber and the second process air chamber do not need to contain fans. The surface cooler in the combined cooling system controls the hot water / cold water flow through the regulating valve to keep the temperature of the fan chamber in a low range. The low temperature airflow flows through the motor casing to achieve passive cooling, eliminating the need for traditional motor fans, simplifying the equipment structure while improving heat dissipation efficiency.
