Description

Technical Field

[0001] The utility model relates to the technical field of dye production equipment, and more specifically, to a device for preparing dye stock solution. Background Art

[0002] Disperse dyes are dyes with relatively small molecules and no water-soluble groups in their structures. Disperse dyes need to be uniformly dispersed in the dye solution with the help of a dispersant to form dyeing. Disperse dyes can dye polyester fibers, acetate fibers and polyamide fibers, and are special dyes for polyester products.

[0003] The preparation of stock solution is the first process in the production of disperse dyes. Pulp making is the process of adding water to dye raw materials and then fully stirring to make dye slurry. At present, enterprises use general stirring tank equipment purchased on the market to carry out the work of preparing stock solution. The general stirring tank equipment only has a conventional stirring function. In actual production, it is found that using the general stirring tank equipment to make pulp has problems such as low pulp-making efficiency and unstable pulp-making quality (there are many lumps in the dye raw materials, and the raw materials cannot be completely dispersed only by the stirring mechanism. For the prepared stock solution, the uniformity of the slurry particles is relatively poor), and cleaning the inside of the tank after pulp making is also a very time-consuming and laborious task. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a device for preparing dye stock solution. This device is specially designed for the production of dye stock solution. First, the crushing roller on the feeding funnel is used to crush the lumped raw materials, so that there is no phenomenon of large pieces falling into the input raw materials. Secondly, during the stirring operation, the inner grinding sleeve and the grinding rod are used to form an abrasive effect on the flowing slurry. The abrasive effect can improve the preparation efficiency of the stock solution, and the uniformity of the particles of the prepared slurry is also significantly improved.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Specific implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] A device for preparing dye stock solution, comprising a pulp barrel 1, a barrel cover 2, a stirring mechanism 3 and an inner grinding sleeve 5. The pulp barrel 1 is used for preparing the dye stock solution. The barrel cover 2 is hermetically installed on the top of the pulp barrel 1 to form a closed pulping environment. The stirring mechanism 3 is installed on the barrel cover 2 and extends into the pulp barrel 1. The stirring mechanism 3 stirs the materials in the pulp barrel 1. The materials refer to the raw materials for producing dyes. After the dye raw materials are put into the pulp barrel 1 and mixed with water, the dye stock solution is made through the stirring action of the stirring mechanism 3. The inner grinding sleeve 5 is installed in the pulp barrel 1 and is closely attached to the inner wall of the pulp barrel 1. A number of abrasive bumps 52 are provided on the inner wall surface of the inner grinding sleeve 5. After the inner grinding sleeve 5 is installed, the materials in the stirring flow can continuously contact the abrasive bumps 52 on the inner grinding sleeve 5. The materials passing through the abrasive bumps 52 can form an abrasive effect, so that the large particle substances in the dye stock solution can be accelerated and dispersed, thereby improving the preparation efficiency of the dye stock solution, and the particle size of the prepared dye stock solution can also be well controlled. In the utility model, a feed funnel 4 is installed on the top of the barrel cover 2. The feed funnel 4 is used for feeding the dye raw materials. A pair of crushing rollers 41 are installed in the feed funnel 4. The crushing rollers 41 are driven by a motor. When feeding, the dye raw materials pass through the crushing rollers 41 before entering the pulp barrel 1. The crushing rollers 41 can crush the large dye raw materials to ensure that there are no large pieces in the input dye raw materials (the dye raw materials have a high viscosity and are easy to agglomerate. If the large dye raw materials are directly put into the pulp barrel 1, they are not easy to be stirred and dispersed, which is easy to affect the preparation efficiency of the stock solution). This design can also further improve the preparation efficiency of the dye stock solution, significantly shortening the preparation time of the stock solution.

[0021] As Figure 1 shown, the stirring mechanism 3 includes a motor 31 and a stirring main shaft 32. The motor 31 is fixedly installed on the top of the barrel cover 2. The stirring main shaft 32 is flange-connected to the output end of the motor 31. A number of groups of stirring blades 33 are connected to the outer wall of the stirring main shaft 32. The number of groups of stirring blades 33 are evenly distributed with the stirring main shaft 32 as the central axis. One group of stirring blades 33 includes a number of stirring blades 33 arranged at equal intervals along the length direction of the stirring main shaft 32. When the motor 31 is started, it can drive the stirring main shaft 32 to rotate to form the rotary motion effect of a number of groups of stirring blades 33. The rotary motion of the stirring blades 33 can stir the materials, making the materials and water fully mixed to form the dye stock solution. Since the stirring main shaft 32 and the output end of the motor 31 are flange-connected, the disassembly and assembly of the two are very convenient. The stirring blades 33 and the stirring main shaft 32 can be flange-connected for easy disassembly and assembly operations.

[0022] As Figure 1As shown in the figure, a number of positioning strips 11 are connected to the inner wall of the pulp bucket 1. The positioning strips 11 are installed vertically, and a number of positioning strips 11 are evenly distributed along the circumferential direction of the inner wall of the pulp bucket 1. A number of card slots 51 are formed on the outer wall surface of the inner grinding sleeve 5. The size and the number of the card slots 51 are matched with the positioning strips 11. When the inner grinding sleeve 5 is installed, the positioning strips 11 are inserted into the card slots 51 one by one. The positioning strips 11 play a role in installing and positioning the inner grinding sleeve 5. After the inner grinding sleeve 5 is installed, it is locked in position by the positioning strips 11, and the inner grinding sleeve 5 cannot rotate in a plane. Therefore, an abrasive effect can be formed on the flowing slurry. A number of bottom supports 12 are fixedly connected to the inner wall of the pulp bucket 1. The number of bottom supports 12 is evenly distributed along the circumferential direction of the inner wall of the pulp bucket 1. The bottom supports 12 are used to support the bottom of the inner grinding sleeve 5. The bottom supports 12 are used as the lower installation limit of the inner grinding sleeve 5. As Figure 1 shown, in the present utility model, the inner grinding sleeve 5 is installed closely against the inner wall of the pulp bucket 1. The inner grinding sleeve 5 occupies most of the area of the inner wall of the pulp bucket 1. After the pulp making is completed, the most slurry remains on the inner grinding sleeve 5. Since the inner grinding sleeve 5 is detachably installed, the inner grinding sleeve 5 can be removed and cleaned at this time. Only a part of the bottom area of the pulp bucket 1 has residual slurry, and only the bottom of the pulp bucket 1 needs to be cleaned. The installation and use of the inner grinding sleeve 5 can greatly facilitate the cleaning operation after each working shift. As Figure 2 shown, a number of evenly distributed threaded holes 55 are formed at the top of the inner grinding sleeve 5. As Figure 1 shown, a lifting ring 56 is threadedly installed in each threaded hole 55. The installation of the lifting ring 56 does not affect the closing of the bucket cover 2. The lifting ring 56 can be threaded with a steel wire rope, and then it can be hung on a lifting device. The inner grinding sleeve 5 can be directly lifted by the evenly distributed steel wire ropes.

[0023] In order to further enhance the abrasive effect on the slurry, as Figure 1 and Figure 2 shown, the present utility model is designed to install a number of grinding rod groups 53 on the inner wall surface of the inner grinding sleeve 5. A number of grinding rod groups 53 are evenly distributed along the circumferential direction of the inner wall of the inner grinding sleeve 5. Each grinding rod group 53 includes a number of grinding rods 531. A number of grinding rods 531 in a grinding rod group 53 are arranged at equal intervals along the height direction of the inner grinding sleeve 5. Relying solely on the inner grinding sleeve 5, only the outer circumference of the slurry contacts the inner grinding sleeve 5. Although there is an abrasive effect, the abrasive efficiency is still relatively low. Therefore, the present utility model installs the grinding rods 531 on the inner wall of the inner grinding sleeve 5. The grinding rods 531 are parallel to the stirring blades 33. The grinding rods 531 extend towards the stirring main shaft 32 but do not contact the stirring main shaft 32. In the height direction of the inner grinding sleeve 5, the grinding rods 531 and the stirring blades 33 are arranged alternately. In this way, the grinding rods 531 block the flow path of the slurry and can fully form an abrasive effect on the slurry. Since the number of the grinding rods 531 is large, the abrasive effect is obvious, the particle size of the particles in the slurry is significantly reduced, and the preparation time of the slurry can also be significantly shortened.

[0024] As Figure 3As shown in the figure, a grinding rod mounting seat 54 is welded and installed on the inner wall surface of the inner grinding sleeve 5. One end of the grinding rod 531 is threadedly connected to the grinding rod mounting seat 54. A number of abrasive bumps 52 are provided on the outer wall surface of the grinding rod 531. The abrasive bumps 52 form an abrasive effect on the passing slurry. The threaded connection of the grinding rod 531 is for convenient disassembly and assembly. When the inner grinding sleeve 5 is removed for cleaning, the grinding rod 531 can be quickly removed from the inner grinding sleeve 5, and the cleaned grinding rod 531 can also be quickly installed and connected.

[0025] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
