Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing, in particular to a multifunctional O-shaped spray pipe for a dye vat. Background Art

[0002] The O-type dye vat is a new type of fabric printing and dyeing equipment with water-saving advantages. It consists of a vat body, a tower head, and a fabric trough. The vat body is a closed cylindrical structure with a horizontal axis and a fabric inlet on its side. The tower head is located above the vat body and houses the fabric circulation conveying mechanism and nozzles. The fabric trough is a C-shaped structure located inside the vat body. The fabric trough has an upper fabric inlet and a lower fabric outlet. The fabric inlet is connected to the outlet of the spray pipe, and the fabric outlet is connected to the inlet of the fabric circulation conveying mechanism.

[0003] The dyeing mainly occurs at the nozzle position. The nozzle is a pipe structure with a twisted fabric passing through the middle. The nozzle has a conical gap that allows the dye liquid to be sprayed from an annular area to the outer surface of the fabric in a radial and oblique backward direction, thereby achieving dyeing. Different types of fabric fibers require different spraying methods. If the fabric is relatively loose, the spraying speed should be lower and a liquid spray method should be used; if the fabric is relatively tight, an air flow should be used to spray the atomized dye liquid onto the fabric. The spraying speed is higher so that the dye liquid can better penetrate the fabric. In the existing technology, the nozzle often has only a single function and cannot meet the dyeing needs of different fabrics.

[0004] Therefore be necessary to improve the O-type dye vat structure to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a multifunctional O-type dye vat spray pipe, which can switch different operating modes, so that the O-type dye vat can be flexibly adapted to the printing and dyeing needs of various fabrics.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a multifunctional O-type dye vat spray pipe, comprising a shell and a front atomization assembly, the shell comprising a fabric channel running through the middle, a liquid flow cavity located outside the inlet side of the fabric channel, and an air flow cavity located outside the outlet side of the fabric channel, a full-ring liquid flow nozzle obliquely arranged rearwardly is provided between the liquid flow cavity and the fabric channel, a full-ring air flow nozzle obliquely arranged rearwardly is provided between the air flow cavity and the fabric channel, the liquid flow cavity is isolated from the air flow cavity, a liquid inlet pipe connected to the liquid flow cavity and an air inlet pipe connected to the air flow cavity are provided on the shell, and the front atomization assembly comprises a plurality of front atomization dye liquid nozzles arranged in the air flow cavity.

[0007] Specifically, the front atomization assembly also includes a front flow-uniform cavity in a C-shape arranged at the lower part of the inner wall of the airflow cavity and a front liquid inlet connecting the front flow-uniform cavity with the outside of the shell. The front atomization dye liquid nozzles are evenly distributed on the front flow-uniform cavity and their spraying direction is toward the front of the central axis of the air intake pipe.

[0008] Specifically, the fabric channel is located in a venturi tube, and the full-annular airflow nozzle is located in the front part of the venturi tube.

[0009] Furthermore, a semi-annular airflow nozzle is provided between the liquid flow cavity and the fabric channel. The semi-annular airflow nozzle is located at the rear of the Venturi tube and the upper semi-annular area is separated by an arc-shaped block.

[0010] Furthermore, the shell is also provided with a rear atomization component, which includes a plurality of rear atomization dye liquid nozzles, a rear uniform flow cavity arranged in a C shape at the lower part of the inner wall of the air flow cavity, and a rear liquid inlet connecting the rear uniform flow cavity and the outside of the shell. The rear atomization dye liquid nozzles are evenly distributed on the rear uniform flow cavity and their spraying direction is toward the rear of the central axis of the air inlet pipe.

[0011] Furthermore, a guide fin is provided at the lower portion of the venturi tube, and the guide fin is located outside the fabric channel and separates the lower portion of the airflow cavity.

[0012] The beneficial effects of the technical solution of this utility model are:

[0013] The utility model can switch between multiple spray modes. When the fabric density is relatively low, the dye liquid is directly sprayed on the fabric using the full-circle liquid flow nozzle. When the fabric density is relatively high, the atomized dye liquid is mixed in the air using the full-circle air flow nozzle and sprayed on the fabric at high speed. This allows the O-type dyeing cylinder to be flexibly applied to fabrics of different materials, reduces the equipment cost of the factory, and achieves the purpose of saving water in multiple working conditions.

[0022] The present invention will be further described in detail below with reference to specific embodiments.

[0023] Example:

[0024] like Figure 1 and Figure 4 As shown, the utility model is a multifunctional O-type spray pipe for dye vats, comprising a shell 1 and a front atomizing assembly 2 and a rear atomizing assembly 3 arranged on the shell 1.

[0025] like Figures 1 to 3 As shown, the shell 1 includes a fabric channel 1a that runs through the middle, a liquid flow chamber 1b located outside the inlet side of the fabric channel 1a, and an air flow chamber 1c located outside the outlet side of the fabric channel 1a. The fabric channel 1a is located in a venturi tube 11. A full-annular liquid flow nozzle 12 is provided between the liquid flow chamber 1b and the fabric channel 1a. A full-annular air flow nozzle 13 is provided between the air flow chamber 1c and the fabric channel 1a. The liquid flow chamber 1b is isolated from the air flow chamber 1c. A liquid inlet pipe 15 connected to the liquid flow chamber 1b and an air inlet pipe 16 connected to the air flow chamber 1c are provided on the shell 1. The full-annular air flow nozzle 12 is located at the front of the venturi tube 11.

[0026] The fabric passes through the spray pipe from fabric channel 1a. The full-circle liquid flow nozzle 12 and the full-circle air flow nozzle 13 are both annular structures, respectively allowing liquid and gas to be sprayed into fabric channel 1a from all sides of the fabric. The dye liquid can enter from the liquid flow chamber 1b and then be sprayed onto the fabric through the full-circle liquid flow nozzle 12. The dye liquid can also be first atomized by the atomizing dye liquid nozzle 21 and then sprayed into the air flow chamber 1c. A high-pressure blower is used to inject high-pressure gas into the air flow chamber 1c from the air inlet pipe 16. The high-pressure gas entrains the dye liquid droplets and sprays them onto the fabric through the full-circle air flow nozzle 13. The Venturi tube 11 is a tube body that is narrow in the middle and widens at the rear. The full-circle liquid flow nozzle 12 is located in the narrow part, so that when air is sprayed into the fabric channel 1a, it exerts a backward pulling force on the fabric. The fabric moves under the pull of the air flow. When passing through the Venturi tube 11, the fabric expands under the action of the air flow. For high-density fabrics, the dye liquid can enter the interior of the fabric, achieving a better dyeing effect. The utility model can switch between multiple spray modes. When the fabric density is relatively low, the full-circle liquid flow nozzle 12 is used to directly spray the dye liquid on the fabric. When the fabric density is relatively high, the full-circle air flow nozzle 13 is used to mix the atomized dye liquid in the air and spray the fabric at high speed. This allows the O-type dyeing cylinder to be flexibly applied to fabrics of different materials, reducing the equipment cost of the factory and achieving the purpose of saving water in multiple working conditions.

[0027] like Figures 1 to 4 As shown, the front atomizing assembly 2 includes a plurality of front atomizing dye liquid nozzles 21, a front uniform flow cavity 22 arranged in a C shape at the lower part of the inner wall of the air flow cavity 1b, and a front liquid inlet 23 connecting the front uniform flow cavity 22 with the outside of the shell 1. The front atomizing dye liquid nozzles are arranged in the air flow cavity 1c, and the front atomizing dye liquid nozzles 21 are evenly distributed on the front uniform flow cavity 22 and their spraying direction is toward the front of the central axis of the air intake pipe 16.

[0028] Part of the air flow entering from the air inlet pipe 16 will go through the full-ring liquid flow nozzle 12 to enter the fabric channel 1a. The spraying direction of the front atomizing dye nozzle 21 will follow the flow direction of this part of the air flow, so the atomized dye can be mixed in the air flow and then sprayed on the fabric.

[0029] like Figure 2 and Figure 3 As shown, a semi-annular airflow nozzle 13 is provided obliquely backward between the liquid flow chamber 1b and the fabric channel 1a. The semi-annular airflow nozzle 13 is located at the rear of the venturi tube 11 and the upper semi-annular area is separated by an arc-shaped block 17.

[0030] The outlet of fabric duct 1a is above the entrance of the fabric trough. Ideally, the fabric should fall directly downward into the trough. However, if the fabric's cross-section is approximately circular, it will move downward in a parabolic trajectory, which may not allow it to be properly directed into the trough. Another portion of the airflow entering through inlet pipe 16 passes through semi-circular airflow nozzles 13 and enters fabric duct 1a. Because its upper portion is unventilated, the airflow is directed more diagonally downward toward the fabric, flattening the stretched fabric. This airflow compresses and slaps the fabric, eliminating problems such as wrinkles and irregular fiber shrinkage, allowing the fabric to enter the trough in optimal condition.

[0031] like Figures 1 to 4 As shown, the rear atomization assembly 3 includes a plurality of rear atomization dye liquid nozzles 31, a rear uniform flow chamber 32 arranged in a C shape at the lower part of the inner wall of the air flow chamber 1b, and a rear liquid inlet 33 connecting the rear uniform flow chamber 32 with the outside of the shell 1. The rear atomization dye liquid nozzles 31 are evenly distributed on the rear uniform flow chamber 32 and their spraying direction is toward the rear of the central axis of the air inlet pipe 16.

[0032] The post-atomizing dye liquid nozzle 31 allows the air flow entering the fabric channel 1a from the semi-annular air flow nozzle 13 to also contain atomized dye liquid, thereby enhancing the printing and dyeing effect.

[0033] like Figure 2 and Figure 3 As shown, a guide fin 18 is provided at the lower portion of the venturi tube 11 . The guide fin 18 is located outside the fabric channel 1 a and separates the lower portion of the airflow cavity 1 c .

[0034] The high-pressure gas entering the air intake pipe 16 will not only be diverted forward and backward, but also diverted left and right around the Venturi tube 11. The guide fins 18 prevent the airflow on both sides from converging below the Venturi tube 11, preventing the formation of air vortexes that affect the stability of printing and dyeing.

[0035] This sprinkler pipe can have at least four working modes:

[0036] 1. Front airflow atomization mode: the liquid inlet pipe 15 does not feed liquid, the air inlet pipe 16 feeds air, and only the front atomization dye liquid nozzle 21 works. For high-count and high-density fiber fabrics, high airflow opens the fabric and atomizes the dye liquid at the same time for dyeing.

[0037] 2. Post-airflow atomization mode: the liquid inlet pipe 15 does not feed liquid, the air inlet pipe 16 feeds air, and only the post-atomization dye liquid nozzle 31 works. For low-strength and low-fiber fabrics, the low airflow drives the fabric to run and open the fabric, and the post-atomization dye liquid is dyed.

[0038] 3. Full liquid flow dyeing mode: liquid is fed into the liquid inlet pipe 15, air is not fed into the air inlet pipe 16, and the front atomizing dye liquid nozzle 21 and the rear atomizing dye liquid nozzle 31 are not working. The fabric is driven by pure liquid flow and printed and dyed at the same time.

[0039] 4. Airflow-Assisted Liquid Dyeing Mode: Liquid is fed through liquid inlet pipe 15, air is fed through air inlet pipe 16, and both the front atomizing dye nozzle 21 and the rear atomizing dye nozzle 31 are inoperative. Liquid flow cooperates with the airflow to open the fabric, allowing dyeing to proceed. This mode is suitable for dyeing and printing fabrics requiring high liquid flow rates, such as for post-processing.

[0040] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
