Description

Technical Field

[0001] This utility model relates to the technical field of water seal devices, specifically to a water seal device with a float. Background Technology

[0002] High-energy gas treatment of fabrics, as a cutting-edge dyeing and finishing technology, demonstrates significant innovative advantages. It can rapidly decompose organic impurities on the fabric surface, achieving highly efficient bleaching and opening up new avenues for fabric processing. Compared to traditional methods that rely on large amounts of chemical reagents, this technology eliminates the need for chemicals, fundamentally preventing chemical residue pollution and making it a truly green and environmentally friendly dyeing and finishing process. Furthermore, it boasts the dual advantages of low cost and significant treatment effects, bringing new development opportunities to the fabric dyeing and finishing industry.

[0003] However, the safe use of high-energy gases (such as ozone) cannot be ignored. Once released into the air, it can adversely affect the health of operators and the environment. Therefore, in practical applications, high-energy gas handling chambers must be strictly sealed to ensure they operate in a safe and controlled environment. In continuous production processes, liquid seal devices are often used to seal gases, but when fabrics pass through these devices, their internal moisture content drops rapidly. If moisture is not replenished in time, the liquid seal device will fail, leading to the risk of high-energy gas leakage. Utility Model Content

[0004] To address the technical shortcomings of existing water seal structures that suffer from loss of sealing performance due to the inability to replenish water in a timely manner during use, this invention proposes a water seal device with a float. This device cleverly employs a dual design of an auxiliary water tank and float detection, enabling precise monitoring of liquid level changes within the water seal device. When fabric passes through the sealing liquid, even if the liquid is carried away, the float water seal can promptly replenish the lost moisture through the automatic water replenishment mechanism of the auxiliary water tank. This effectively solves the problem of the inability to replenish water in a timely manner when the liquid level drops in existing technologies, ensuring that the water seal device always maintains reliable sealing performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a water-sealing device with a float ball, applied to a fabric processing equipment with a gas finishing unit. The fabric processing equipment with a gas finishing unit includes a gas finishing chamber. The water-sealing device includes a liquid-sealed water tank installed on the gas finishing chamber of the fabric processing equipment with a gas finishing unit, and a secondary water tank installed on one side of the liquid-sealed water tank. A mounting frame is fixed between the two, and a float ball assembly is fixed inside the mounting frame. The liquid-sealed water tank and the secondary water tank are connected by a connecting pipe.

[0006] Furthermore, the bottom end of the float assembly is connected to a three-way pipe, one end of which is connected to a connecting pipe, and the other end is connected to an external waterway. Furthermore, a one-way valve is fixed in the middle of the external water passage; A hydraulic roller assembly is fixed on the water-sealing device; The liquid-pressing roller assembly includes a housing, a face frame fixed to the outside of the housing, and a water-squeezing roller disposed in the face frame; A fixing rod is provided in the middle of the water-squeezing roller. The fixing rod is located in the face frame, and grooves are provided in the middle of the face frame. The portion of the fixing rod protruding from the groove is fitted with a connecting frame, and a spring is fixed between the connecting frames on both sides.

[0007] Furthermore, the trough is a long, narrow trough structure, and the spacing of the squeezing rollers is adapted to the thickness of the fabric.

[0008] Furthermore, the float assembly includes two sets of floats, and the two sets of floats are respectively disposed in the liquid-sealed water tank and the auxiliary water tank; Furthermore, there is a mounting bracket between the liquid-sealed water tank and the auxiliary water tank, and a sliding tube is fixed on the mounting bracket; Furthermore, the two sets of floats are connected by a connecting rod, which is connected to the sliding tube.

[0009] Furthermore, the middle of the two sets of float connecting rods is connected to the sliding mechanism in the sliding tube.

[0010] Furthermore, the valve on the connecting pipe is connected to a sliding mechanism, and the valve can be opened and closed by the displacement of the sliding mechanism.

[0011] Furthermore, the water-sealing device is equipped with multiple sets of rollers for conveying and guiding the fabric.

[0012] Furthermore, one end of the external water channel is connected to an external water source.

[0013] Compared with the prior art, this utility model has the following advantages: By installing floats in both the liquid-sealed water tank and the auxiliary water tank, and connecting the two sets of floats via a connecting rod, with the middle of the connecting rod connected to a sliding mechanism in the sliding tube, the liquid level can be automatically adjusted according to changes in the liquid levels of the liquid-sealed water tank and the auxiliary water tank. When the liquid level in the liquid-sealed water tank drops, liquid in the auxiliary water tank can automatically flow into the liquid-sealed water tank to maintain the liquid level in the liquid-sealed water tank, ensuring that the liquid level always submerges the lowest point of the V-shaped path of the fabric. This continuously maintains the sealing function of the water-sealing device, effectively solving the problem of seal failure caused by liquid level drop in existing technologies, improving the reliability and stability of the water-sealing device, and ensuring the sealing effect between the gas conditioning chamber and the atmospheric environment.

[0014] The installed pressure roller assembly can squeeze out excess liquid from the fabric, reducing the impact of water on subsequent processes and improving fabric processing quality and production efficiency. At the same time, it improves water utilization and reduces water waste, resulting in significant economic and environmental benefits.

[0015] The automatic control of the float assembly and sliding mechanism enables automated operation of the water seal device, eliminating the need for manual intervention and significantly reducing the labor intensity of operators while improving equipment efficiency and reliability. Furthermore, the device's rational structural design and simple, reliable connections and coordination between components facilitate maintenance and repair, further reducing maintenance costs and management complexity, and extending the equipment's lifespan and economic benefits.

[0016] The water-sealing device has been optimized by introducing innovative structures such as an auxiliary water tank, a float assembly, and a pressure roller assembly. The organic integration of these structures enhances the overall performance of the water-sealing device, making it more structurally sound and functionally complete. This allows it to better adapt to various complex operating conditions in industrial production, meeting the demands of continuous, efficient, and energy-saving production, and possessing broad application prospects and significant market competitiveness.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] A water-sealing device with a float, see attached. Figure 1 -Appendix Figure 5 A water-sealing device with a float is provided, see [link to relevant documentation]. Figure 1 The water sealing device includes a liquid-sealed water tank 4 installed on the gas finishing chamber of the fabric processing equipment 1. A secondary water tank 5 is provided on one side of the liquid-sealed water tank 4. A mounting frame 7 is provided between the liquid-sealed water tank 4 and the secondary water tank 5. A sliding tube 8 is fixed inside the mounting frame 7. See Figure 2 At the bottom end of the sliding tube 8 of the water-sealing device is a three-way pipe 81. One end of the three-way pipe 81 is connected to the connecting pipe 6, and the other end is connected to the external water passage 83. A one-way valve 82 is installed on the external water passage 83, and a hydraulic roller assembly 9 is fixed on the water-sealing device. The external water passage can input water into the auxiliary water tank 5 through the one-way valve 82 and the connecting pipe 6.

[0027] See Figure 3-5 The liquid-pressing roller assembly 9 includes a housing 91, a face frame 95 fixed to the outside of the housing 91, and a squeezing roller 92 disposed within the face frame 95. A fixing rod 93 is located in the middle of the squeezing roller 92, and the fixing rod 93 is mounted on the face frame 95. The face frame 95 has a groove 951. A connecting frame 94 is fitted onto the portion of the fixing rod 93 protruding from the groove 951. A spring 96 is fixed between the two connecting frames 94 on either side. The other end of the fixing rod 93 is disposed on a limiting frame 97. Pressure is applied to the squeezing roller 92 by the spring 96, thereby squeezing out the liquid from the fabric.

[0028] See Figure 1-2The float assembly includes two sets of floats, which are respectively installed in the liquid-sealed water tank 4 and the auxiliary water tank 5. The two sets of floats are connected by a connecting rod. The middle of the connecting rod of the two sets of floats is connected to the sliding mechanism in the sliding tube 8. The floats will tilt according to the changes in the liquid level of the liquid-sealed water tank 4 and the auxiliary water tank 5, thereby causing the sliding mechanism in the sliding tube 8 to change position.

[0029] The liquid-sealed water tank 4 and the auxiliary water tank 5 are connected by a connecting pipe 6. The connecting pipe 6 has a valve connected to a sliding mechanism, which controls the opening and closing of the valve through displacement of the sliding mechanism. When the liquid levels in the liquid-sealed water tank 4 and the auxiliary water tank 5 are inconsistent, the heights of the two sets of floats will also be inconsistent, causing the connecting rod to tilt. This tilting of the connecting rod drives the sliding mechanism to slide, thereby controlling the valve on the connecting pipe 6 and allowing liquid from the auxiliary water tank 5 to flow into the liquid-sealed water tank 4. When the liquid levels in the auxiliary water tank 5 and the liquid-sealed water tank 4 are equal, the tilt angle of the connecting rod returns to zero, and the sliding mechanism closes the valve on the connecting pipe 6.

[0030] Furthermore, the water-sealing device is equipped with multiple sets of rollers 3, which convey and guide the fabric 2, and the fabric 2 passes through the liquid-sealed water tank 4.

[0031] During operation, when the fabric 2 enters the gas cleaning chamber of the gas cleaning unit or enters the next processing flow from the gas cleaning chamber of the gas cleaning unit, it is conveyed and guided by multiple sets of rollers 3. Through a water sealing device, one side of the water sealing device is connected to the gas cleaning chamber. The fabric passes through the water sealing device in a V-shaped path, and the liquid surface is immersed at the lowest end of the V-shaped path of the fabric. One side of the V-shaped path of the fabric is the environment of the gas cleaning chamber, and the other side is the atmospheric environment. The water seal isolates the two sides, thereby achieving a seal between the gas cleaning chamber and the atmospheric environment.

[0032] During continuous operation, the fabric carries away a large amount of water as it passes through the liquid-sealed water tank 4, causing the liquid level in the tank to drop rapidly. When the liquid level drops to the lowest point of the fabric's V-shaped path, the water seal device loses its sealing function. To solve this problem, this invention introduces a secondary water tank 5, with two sets of floats positioned between the secondary water tank 5 and the liquid-sealed water tank 4. These two sets of floats are connected by a connecting rod; simultaneously, the middle of the connecting rod is connected to a sliding mechanism in the sliding tube 8. When the liquid levels in the liquid-sealed water tank 4 and the secondary water tank 5 change, the floats tilt accordingly, causing the sliding mechanism in the sliding tube 8 to change position. If the liquid levels in the liquid-sealed water tank 4 and the secondary water tank 5 are inconsistent, the heights of the two sets of floats will also differ, causing the connecting rod to tilt. The tilting of the connecting rod drives the sliding mechanism to slide, thereby controlling the valve on the connecting pipe 6 to open, allowing liquid from the secondary water tank 5 to flow into the liquid-sealed water tank 4. When the liquid levels in the auxiliary water tank 5 and the liquid-sealed water tank 4 return to the same height, the tilt angle of the connecting rod returns to zero, and the sliding mechanism slides and closes the valve on the connecting pipe 6.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
