Description

Technical Field

[0001] The present invention relates to the technical field of sizing processes in textile production, and specifically to an automatic control system for the cooling water of the stirring shaft of a sizing barrel. Background Art

[0002] During the weaving production process in the textile industry, when sizing the sizing agent in the sizing process, it is necessary to stir and evenly mix the sizing agent in the sizing barrel to make a sizing liquid suitable for sizing the warp yarns. Inside the sizing barrel, it is necessary to continuously stir the sizing liquid with a stirring shaft. Since heat is generated by the movement of the stirring shaft, too high a temperature will affect the quality of the sizing liquid and the service life of the stirring shaft. The continuously moving stirring shaft needs to be cooled in time. Currently, the traditional method is to continuously inject water from tap water to cool the stirring shaft, resulting in a large amount of tap water consumption and serious waste of water resources. Summary of the Invention

[0003] To overcome the deficiencies of the prior art, the object of the present invention is to provide an automatic control system for the cooling water of the stirring shaft of a sizing barrel, which can cool the stirring shaft by the control system when the stirring shaft is moving, not only improving the service life of the stirring shaft of the sizing barrel, ensuring that the sizing product meets the quality requirements, but also achieving the effect of saving water.

[0004] To achieve the above object of the invention, the present invention includes a sizing barrel, a stirring shaft, a stirring motor, a cooling water tank, a controller, and an electromagnetic water valve; one end of the stirring shaft is connected to the stirring motor, and the other end extends into the sizing barrel to stir the sizing liquid. A cooling water tank for reducing the temperature of the stirring shaft is provided at the contact between the stirring shaft and the outer body of the sizing barrel. The cooling water tank is connected to a tap water pipe, and an electromagnetic water valve connected to the controller is provided on the tap water pipe. The controller is connected to the stirring motor.

[0005] Further, a sealing device for preventing cooling water from entering the inside of the sizing barrel is provided at the contact between the stirring shaft and the outer body of the sizing barrel.

[0006] Further, the cooling water tank is also provided with a drain pipe, and the drain pipe is connected to the sewage pipe network.

[0007] Further, the controller is a PLC controller. The controller receives the signal of the start of the stirring motor and transmits this signal to the electromagnetic water valve to control the electromagnetic water valve to start the tap water pipe switch.

[0008] Further, the tap water pipe is connected to deep well water underground.

[0009] Compared with the prior art, when the stirring motor of the sizing barrel starts in the present invention, the motor start signal is fed back to the controller, and the controller controls the electromagnetic water valve to start, thereby driving the tap water pipe to open. Cooling water is injected from the tap water pipe into the cooling water tank of the stirring shaft to achieve the purpose of reducing the temperature of the stirring shaft and reducing the waste of water resources.

[0013] For a clearer understanding of the present invention, the following is a detailed description in conjunction with embodiments.

[0014] As Figure 1 , Figure 2 shown, the present invention mainly includes a sizing vat 1, a stirring shaft 2, a stirring motor 3, a cooling water tank 4, a controller 5, and an electromagnetic water valve 6. One end of the stirring shaft 2 is connected to the stirring motor 3, and the other end extends into the sizing vat 1 to stir the slurry by an impeller. A cooling water tank 4 for reducing the temperature of the stirring shaft 2 is provided at the contact position between the stirring shaft 2 and the outer body of the sizing vat 1. The cooling water tank 4 is connected to the water pipe 7, and the water pipe 7 is provided with an electromagnetic water valve 6 connected to the controller 5. The controller 5 is connected to the stirring motor 3.

[0015] Preferably, a sealing device 8 is provided at the contact position between the stirring shaft 2 and the outer body of the sizing vat 1. The sealing device 8 is a mechanical seal, which can prevent fluid leakage. Under the action of fluid pressure and the elastic force of the sealing device 8 itself, the sealing device 8 is kept in contact with the sizing vat 1 and the stirring shaft 2. The sealing device 8 is configured with the KS104-5 model.

[0016] Preferably, the cooling water tank 4 is further provided with a drain pipe 9, and the drain pipe 9 is connected to the sewage pipe network of the production site.

[0017] Preferably, the controller 5 is a PLC controller. The controller 5 receives the signal for starting the stirring motor 3 and transmits this signal to the electromagnetic water valve 6 to control the electromagnetic water valve 6 to open the water pipe 7.

[0018] Preferably, the controller 5 mainly uses Siemens S7-200 PLC as the core for control. The electromagnetic water valve 6 is a pilot-operated solenoid valve, and its structure is mainly composed of a pilot valve and a main valve. The main valve adopts a rubber seal structure, and the electromagnetic water valve 6 is configured with the Delixi model of 2W160-15-AC220V (4-point thread). In the normal position, the movable iron core seals the pilot valve port, the pressure in the valve cavity is balanced, and the main valve port is closed. When the coil is energized, an electromagnetic force is generated to suck up the movable iron core, and the medium in the main valve cavity leaks out from the pilot valve port, resulting in a pressure difference. The diaphragm or valve cup is quickly lifted, the main valve port is opened, and the electromagnetic water valve 6 is opened. When the coil is de-energized and the magnetic field disappears, the movable iron core resets and closes the pilot valve port. After the pressure in the pilot valve and the main valve cavity is balanced, the electromagnetic water valve 6 is disconnected. The electromagnetic water valve 6 can accurately complete the on-off command under the control of the controller 5.

[0019] Preferably, the water supply pipe 7 is connected to the deep well water underground in the production site.

[0020] During use, the stirring motor 3 of the present invention is connected to the controller 5, and the controller 5 is connected to the electromagnetic water valve 6 that controls the start of the water supply pipe 7. When the stirring motor 3 starts and drives the stirring shaft 2 to stir the slurry in the slurry mixing tank 1, the controller 5 controls the electromagnetic water valve 6 to be attracted, thereby driving the water supply pipe 7 to open. The deep well water connected to the water supply pipe 7 is pumped into the cooling water tank 4 to cool the continuously rotating stirring shaft 2. The remaining water after cooling flows through the drain pipe 9 to the sewage pipe network in the production site.

[0021] The present invention reduces the amount of cooling water used, avoids the occurrence of the phenomenon that the cooling water still flows into the cooling water tank 4 when the stirring shaft 2 stops rotating, and saves water resources.
