Description

Technical Field

[0001] The utility model relates to a dyeing machine, in particular to a dyeing machine with a low bath ratio, belonging to the technical field of dyeing and finishing equipment. Background Art

[0002] Under the environment of green environmental protection, low-carbon economy and continuous development of dyeing and finishing technology, the solubility and stability of dyes used for dyeing are getting better and better, which creates favorable conditions for small bath ratio dyeing. Small bath ratio dyeing can not only speed up the dyeing rate, but also improve the fixation rate to a certain extent, while reducing the amount of dye solution, water, steam, auxiliaries, etc., improve the utilization rate of dye solution and auxiliaries, and improve the reproducibility of dyes; small bath ratio dyeing machines have obvious energy-saving, consumption-reducing and emission-reducing effects; therefore, it is urgently needed to improve the previous large bath ratio (1:9-10) dyeing machines. Utility Model Content

[0003] In order to solve the problems of large bath ratio dyeing machines in the past due to large dyeing liquid volume, high energy loss, high emissions, etc., the utility model provides a low bath ratio dyeing machine, which can save energy, reduce energy consumption and reduce emissions by reducing the bath ratio.

[0004] The low bath ratio dyeing machine described in the utility model comprises a dyeing vat, a cloth lifting device and a cloth dyeing device, wherein the cloth lifting device is arranged at the front part of the dyeing vat and comprises a cloth lifting roller and a nozzle, and the cloth dyeing device is arranged at the middle part of the dyeing vat and comprises a double cloth groove cylinder screen, a water drum device and a tail screen, wherein the water drum device is connected to the inner wall of the dyeing vat, a cloth guide pipe extending to the nozzle is arranged at the tail part of the dyeing vat, and a reflux pipe connected to the cloth guide pipe is arranged in the middle part of the dyeing vat.

[0005] Furthermore, the front part of the dye vat is tilted upward at 30°-50° horizontally, and the middle part and the tail part of the dye vat are tilted upward at 1.5°-5° horizontally.

[0006] Furthermore, the water drum device is installed at the bottom of the screen in the vat and is rigidly connected to the inner wall of the dye vat.

[0007] Furthermore, the water drum device is a closed cavity structure, covering the entire middle part of the dye vat.

[0008] Furthermore, the cross section of the closed cavity structure remains consistent, and the inclination angle is consistent with the horizontal inclination angle of the middle of the dye vat.

[0009] The dyeing machine with a low bath ratio structure described in the utility model has a reasonable structural design. By improving the punching layout of the cylinder screen and adding a water drum device at the bottom of the double-cloth groove cylinder screen to form a closed bottom cavity, the storage space for dye solution and the complicated process of excessive punching holes at the bottom of the cylinder screen are reduced. In the whole cycle dyeing process, the low bath ratio machine (1:4-7) is realized, and the manufacturing difficulty is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] As shown in the above figure, the dyeing machine with a low bath ratio structure described in the utility model includes a dyeing vat 10, which is divided into three parts: a dyeing vat front part 3, a dyeing vat middle part 4 and a dyeing vat tail part 5; it also includes a cloth lifting device and a cloth dyeing device, the cloth lifting device is arranged at the front part of the dyeing vat, the cloth lifting device includes a cloth lifting roller 2 and a nozzle 1, the cloth dyeing device is arranged in the middle part of the dyeing vat, and includes a double cloth groove cylinder screen 7, a water drum device 8 and a tail screen 9, wherein the water drum device 8 is connected to the inner wall of the dyeing vat, the tail part of the dyeing vat is provided with a cloth guide pipe 6 extending to the nozzle 1, and the middle part 4 of the dyeing vat is provided with a reflux pipe 11 connected to the cloth guide pipe 6. The front part 3 of the dye vat is horizontally inclined upward by 30°-50°, and the middle part 4 and the tail part 5 of the dye vat are horizontally inclined upward by 1.5°-5°; the water drum device 8 is installed at the bottom of the sieve 7 in the double cloth groove cylinder and is rigidly connected to the inner wall of the dye vat. The water drum device 8 is a closed cavity structure, covering the entire middle part 4 of the dye vat. The cross-section of the closed cavity structure remains consistent, and the inclination angle is consistent with the horizontal inclination angle of the middle part of the dye vat.

[0015] The working principle of the utility model is as follows: the fabric to be dyed passes through the lifting roller 2 of the front part 3 of the dyeing vat, and the fabric is sent to the cloth guide pipe 6 and the double cloth groove cylinder screen 7 in the middle part 4 of the dyeing vat through the nozzle 1 for dyeing. In this process, the excess dye in the fabric is squeezed and released through the smaller space of the tail screen 9. The dye passes through the return water structure and quickly returns to the reflux pipe 11. The closed cavity formed by the water drum device 8 at the bottom of the dyeing vat 10 effectively reduces the excessive useless dye at the bottom of the vat. In the process of immersion dyeing, the fabric is connected head to tail to form a closed loop. Under the action of the lifting roller 2 structure in the front part 3 of the dyeing vat, the fabric continuously passes through the cloth guide pipe 6 from the nozzle 1, enters the tail part 5 of the dyeing vat, the middle part 4 of the dyeing vat and the front part 3 of the dyeing vat, and is lifted by the lifting roller 2 and sent to the cylinder screen 7 for cyclic dyeing.

[0016] It should be noted that the dyeing machine with a low bath ratio structure described in the utility model is not limited to the above-mentioned specific implementation mode. Without departing from the principle and spirit of the utility model, various changes and modifications can be made to the utility model, or some of the features therein can be replaced, all of which are within the technical solution protected by this patent.
