The rotating disc has less damage to the cloth than the split type multi-fan blade. The plurality of fan plates in the rotating disc have a high periphery, and the fan plates with a high periphery have a large driving force of the water flow due to a large peripheral linear velocity, so that a water flow with a large speed can be driven. When water is drained, the water on the rotating disc can flow from the center to the periphery of the disc body, and the fan plates are basically not accumulated with water, so that the rotating disc is basically not accumulated with water.

Detailed Implementation

[0034] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] like Figure 1 An environmentally friendly pretreatment device for printing and dyeing includes a water supply pipe 1, an outer casing 2, and multiple pretreatment liquid tanks 3, such as... Figure 2 The environmentally friendly pretreatment device for printing and dyeing also includes an inner cylinder 4, a turntable 5, a rotary drive 6, a drain pipe 7, an overflow pipe 8, a heating coil 9, and an insulation jacket 10.

[0036] The inner cylinder 4 is mounted on the inner bottom surface of the outer casing 2 via a bracket 11. Both the inner cylinder 4 and the upper end of the outer casing 2 are open.

[0037] The upper edge of the outer shell 2 also wraps horizontally inward to the upper edge of the inner cylinder 4 to protect the mounting parts on the outer wall of the inner cylinder 4.

[0038] The heating coil 9 is wound around the outer peripheral wall of the inner cylinder 4. The insulation sleeve 10 can be insulation cotton, which wraps the heating coil 9. The heating coil 9 can heat the liquid in the inner cylinder 4, and the insulation cotton keeps it warm, saving energy and improving pretreatment efficiency.

[0039] Multiple pretreatment liquid tanks 3 are connected to the inner cylinder 4 via pipes passing through the outer shell 2. Each pipe is equipped with a pump 12 and a solenoid valve 13 to draw pretreatment liquid into the inner cylinder 4. The solenoid valve 13 controls the opening and closing of the pipe. A water supply pipe 1 also passes through the outer shell 2 and connects to the inner cylinder 4. A solenoid valve 13 can also be installed on the water supply pipe 1 to control the water flow. An overflow pipe 8 is located between the inner cylinder 4 and the outer shell 2, with its upper end connected to the inner cylinder 4. The interface between the overflow pipe 8 and the inner cylinder 4 is lower than the interface between each pretreatment liquid tank 3 and the inner cylinder 4, and also lower than the interface between the water supply pipe 1 and the inner cylinder 4. This prevents floating debris in the overflow liquid from clogging the interface between the water supply pipe 1 and the pretreatment liquid tank 3 on the inner cylinder 4.

[0040] The aforementioned pretreatment liquid tanks 3 can be alkaline liquid tanks, acid liquid tanks, degreasing agent tanks, etc., to remove fabric adhesive, metal ions, neutralize alkaline liquid, remove oil stains, etc.

[0041] The rotary actuator 6 can be an electric motor, which is mounted below the inner cylinder 4. Its stator can be fixed to the inner bottom surface of the outer casing 2, and its rotor can enter the inner cylinder 4 through a rotating seal passing through the bottom surface of the inner cylinder 4. After the upper end of the rotor enters the inner cylinder 4, it is fixedly connected to the turntable 5. The turntable 5 is parallel to the bottom surface of the inner cylinder 4. The lower end of the inner sidewall of the inner cylinder 4 has an inwardly protruding inner ring 401, which is spaced around the circumference of the turntable 5, and the gap width between the inner ring 401 and the turntable 5 is equal everywhere.

[0042] like Figure 3 To facilitate drainage, the upper surface of the inner convex ring 401 gradually slopes downwards from the outer circumference to the inner circumference. For example... Figure 4The rotating disc 5 comprises a disc body 501 and a plurality of fan plates 502, for example six fan plates 502. The upper surface of the disc body 501 is substantially conical, but the top end is not sharp, but is approximately spherical. For example, the upper surface of the disc body 501 is divided into a spherical top end region 5011 and a circular side surface region 5012. The circular side surface region 5012 is shaped like the side surface of a circular truncated cone. The peripheral edge of the top end region 5011 is connected to the upper peripheral edge of the circular side surface region 5012, which facilitates the discharge of liquid, which can flow from the center to the periphery and into the gap between the inner convex ring 401 and the rotating disc 5. The six fan plates 502 are fixed vertically along the radial direction of the disc body 501 on the circular side surface region 5012, and the included angle between each adjacent two fan plates 502 is 60°, which facilitates the stirring of a large speed water flow. The upper surface of the fan plate 502 is arc-shaped, which reduces the damage to the cloth. The end of the fan plate 502 close to the peripheral edge of the disc body 501 is higher than the end close to the center of the disc body 501, and the end of the fan plate 502 close to the peripheral edge of the disc body 501 is also higher than the center of the disc body 501. Since the peripheral speed is large, the higher fan plate 502 at the peripheral edge can stir a large speed water flow, which improves the pretreatment efficiency. The lower fan plate 502 close to the center of the disc body 501 is because the liquid level is low at the center of the centrifugal water flow, and this setting is beneficial to the soaking of the cloth into the liquid, which improves the uniformity of the treated cloth.

[0043] The drain pipe 7 is connected to the bottom of the inner cylinder 4 and communicates with the gap between the inner convex ring 401 and the rotating disc 5, so that the liquid entering the gap can be collected to the drain pipe 7 and discharged from the device. The liquid can be a pretreatment liquid or washing water. The drain pipe 7 can be connected to a liquid environmental protection treatment device for environmental protection treatment, and finally discharge relatively clean water.

[0044] The electromagnetic valve 13 is arranged on the drain pipe 7, and the lower end of the overflow pipe 8 is connected to the pipe section of the drain pipe 7 behind the electromagnetic valve 13, so as to freely overflow.

[0045] The environmental protection printing and dyeing pretreatment device of the above various embodiments can stir a large speed water flow, is beneficial to drainage, has small damage to the cloth, can solve the problem that the fan blade as a stirring element has large damage to the cloth and some rotating discs 5 have small force or are prone to water accumulation, and has a broad application prospect.

[0046] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
