Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric production technology, and in particular to a dry powder feeding bucket for a dyeing machine with a crushing function. Background Technology
[0002] Currently, various dyeing machines on the market are striving to reduce the dyeing liquor ratio. When dyeing various cellulosic fabrics with reactive dyes, a large amount of salt (including sodium chloride, sodium sulfate, etc.) is required as a dyeing accelerator, at a dosage of 30-100 g / L. A large amount of alkali (sodium bicarbonate, alternative alkalis, etc.) is used for color fixing, at a dosage of 10-30 g / L. The traditional method is to dissolve the salt or alkali into a solution and inject it into the dyeing machine through pipes. The dyeing liquor then comes into contact with the fibers to promote dyeing and fix the color. Due to the limited solubility of salts and alkalis, a large amount of water is required for complete dissolution, thus increasing the amount of dye liquor used in the dyeing machine and significantly increasing the dyeing liquor ratio (increasing water consumption by 5-20%). This significantly increases water costs, steam costs for heating, and wastewater treatment costs. The discharge of treated wastewater not only increases costs but also increases environmental pollution.
[0003] In summary, when adding salt and alkali to the dyeing machine using existing technology, the dyeing bath is relatively high, which increases costs and causes serious environmental pollution. Utility Model Content
[0004] The purpose of this utility model is to provide a dry powder feeding tank for a dyeing machine with a crushing function, which aims to solve the technical problem that when salt and alkali are added to the dyeing machine in the prior art, the dyeing bath ratio is relatively high, which increases the cost and causes serious environmental pollution.
[0005] To achieve the above objectives, this utility model employs a dry powder feeding hopper for a dyeing machine with a pulverizing function, comprising a feeding hopper body, a support assembly, a pulverizer, a drive component, and a stirring assembly. The support assembly is fixedly connected to the feeding hopper body, the pulverizer is disposed inside the feeding hopper body, and the outer casing of the pulverizer is fixedly connected to the feeding hopper body. The top of the feeding hopper is open, and the lower end of the feeding hopper body has a discharge port.
[0006] The drive unit is mounted on the main body of the feeding tank, and the output end of the drive unit is connected to the stirring assembly, which is placed inside the main body of the feeding tank.
[0007] The stirring assembly includes a drive shaft and a stirring impeller. The drive shaft is connected to the output end of the drive component, the stirring impeller is fixedly connected to the outer wall of the drive shaft, and the end of the drive shaft away from the drive component is connected to the inner sleeve of the pulverizer.
[0008] The impeller has at least two blades.
[0009] The support assembly includes multiple feeding barrel legs, all of which are fixedly connected to the main body of the feeding barrel.
[0010] The driving component includes a bracket and a reducer, with the reducer mounted on the main body of the feeding hopper via the bracket.
[0011] This utility model discloses a dry powder feeding hopper for a dyeing machine with a pulverizing function. In specific use, powder (powdered salt and alkali) is added through the opening at the top of the feeding hopper body. The driving component, as the power source, drives the blades through the transmission shaft to stir the powder evenly. Then, under the action of gravity, the powder enters the pulverizer. The inner sleeve of the pulverizer rotates, and at this time, the inner and outer sleeves of the pulverizer compress and grind the powder. The pulverized and ground powder is sent out through the discharge port at the bottom of the feeding hopper body and transported through a pipeline to the dyeing liquid inside the dyeing machine for dissolution. This method solves the technical problems of existing technologies that require a large amount of water to dissolve salt and alkali when adding them to the dyeing machine, resulting in a high dyeing bath, which increases costs and causes serious environmental pollution.
[0012] This significantly reduces the dyeing bath ratio (reducing water consumption by 5-20%), substantially decreasing water costs, steam costs for heating, and wastewater treatment costs. Simultaneously, the reduced wastewater discharge lowers environmental pollution while lowering costs. Furthermore, it improves dyeing quality and efficiency. Additionally, it can finely grind and refine clumps of salt and alkali during storage and transportation due to moisture absorption, increasing solvent uniformity and enhancing dyeing quality.

[0021] The stirring assembly includes a drive shaft 103 and a stirring impeller 104. The drive shaft 103 is connected to the output end of the drive member, the stirring impeller 104 is fixedly connected to the outer wall of the drive shaft 103, and the end of the drive shaft 103 away from the drive member is connected to the inner sleeve of the pulverizer 102.
[0022] The impeller 104 has at least two blades 109.
[0023] In this specific embodiment, during actual use, powder 100 (powdered salt and alkali) is added through the opening at the top of the feeding tank body 101. The driving component, as the power source, drives the blades 109 through the transmission shaft 103 to stir the powder 100 evenly. Then, under the action of gravity, the powder 100 enters the pulverizer 102. The inner sleeve of the pulverizer 102 rotates, and at this time, the inner and outer sleeves of the pulverizer 102 compress and grind the powder 100. The pulverized and ground powder 100 is sent out through the discharge port 108 at the bottom of the feeding tank body 101 and transported through a pipeline to the dyeing liquid inside the dyeing machine for dissolution. This method solves the technical problems in the prior art where adding salt and alkali into the dyeing machine requires a large amount of water for dissolution, resulting in a high dyeing bath, which increases costs and causes serious environmental pollution.
[0024] This significantly reduces the dyeing bath ratio (reducing water consumption by 5-20%), substantially decreasing water costs, steam costs for heating, and wastewater treatment costs. Simultaneously, the reduced wastewater discharge lowers environmental pollution while lowering costs. Furthermore, it improves dyeing quality and efficiency. Additionally, it can finely grind and refine clumps of salt and alkali during storage and transportation due to moisture absorption, increasing solvent uniformity and enhancing dyeing quality.

[0026] In this specific embodiment, placing multiple feeding bucket support legs 105 on the ground can improve the stability of the feeding bucket body 101.
[0027] Secondly, the driving component includes a bracket 106 and a reducer 107, and the reducer 107 is mounted on the feeding barrel body 101 via the bracket 106.
[0028] In this specific embodiment, the reducer 107 is fixed to the feeding barrel body 101 by the bracket 106.
[0029] Using the dry powder feeding hopper of the dyeing machine with pulverizing function of this utility model, in specific use, powder 100 (powdered salt and alkali) is added through the opening at the top of the feeding hopper body 101. The driving component, as the power source, drives the blades 109 through the transmission shaft 103 to stir the powder 100 evenly. Then, under the action of gravity, the powder 100 enters the pulverizer 102. The inner sleeve of the pulverizer 102 rotates. At this time, the inner and outer sleeves of the pulverizer 102 squeeze and pulverize the powder 100. The pulverized and ground powder 100 is sent out through the discharge port 108 at the bottom of the feeding hopper body 101 and transported through the pipeline to the dyeing liquid inside the dyeing machine for dissolution. This method solves the technical problems of the prior art, which requires a large amount of water to dissolve salt and alkali when adding them to the dyeing machine, resulting in a high dyeing bath, which increases costs and causes serious environmental pollution.
[0030] This significantly reduces the dyeing bath ratio (reducing water consumption by 5-20%), substantially decreasing water costs, steam costs for heating, and wastewater treatment costs.
