Description

Technical Field

[0001] The utility model relates to the field of stirring equipment, in particular to stirring equipment for producing fluorescent whitening agents. Background Art

[0002] Fluorescent whitening agent is a fluorescent dye, or white dye, and is also a complex organic compound. Its characteristic is that it can excite the incident light to produce fluorescence, so that the dyed substance obtains a glittering effect similar to fluorite, making the substance seen by the naked eye very white. Fluorescent whitening agent is a color conditioner with the effect of brightening and enhancing color. It is widely used in papermaking, textiles, detergents and other fields. It increases the white light emitted by the fabric, and the naked eye can feel that the white fabric becomes significantly brighter. This is the brightening effect, so it can compensate for the unwanted yellowish color in the matrix, and at the same time reflect more visible light than the original incident wavelength, making the product appear whiter, brighter and more colorful.

[0003] During the production process of fluorescent whitening agents, mixing and stirring equipment is required to mix and stir the various raw materials of fluorescent whitening agents.

[0004] The structure of mixing and stirring equipment generally includes a mixing barrel, a mixing shaft, a mixing blade, a rotating power device, etc. Among them, the mixing barrel, a mixing shaft, and a mixing blade can be made of wear-resistant and high-temperature resistant materials, which can adapt to high temperature, high speed, and high-efficiency working environment. The rotating power device is generally various types of motors that can provide effective power.

[0005] Most of the existing mixing and stirring equipment have a simple structure and can only achieve the effect of stirring and mixing, but cannot effectively control the feed amount, which will result in too much or too little feed. When too much feed is fed, it will cause uneven mixing, and too much and too heavy material will easily damage the mixing equipment. Feeding too little feed will make it impossible to ensure that a single mixing can meet production requirements, thus causing problems of low production efficiency and excessive energy consumption.

[0034] Reference Figure 1-Figure 3, the stirring mechanism includes a motor 3, which plays a role in providing power. The motor 3 is fixedly connected to the top of the barrel cover 2, and the output end of the motor 3 is fixedly connected to a stirring shaft 4. The outer periphery of the stirring shaft 4 is fixedly connected to a plurality of stirring rods 5, and the bottom end of the stirring shaft 4 is fixedly connected to a stirring blade 6, which plays a role in mixing and stirring the raw materials. The side of the stirring shaft 4 away from the motor 3 is fixedly connected to a scraper 23, which plays a role in avoiding material waste. The locking mechanism 21 includes a mounting shell 2101, which plays a role in fixing the structure inside the shell. An extrusion spring 2104 is fixedly connected to the inside of the mounting shell 2101, which plays a role in providing elastic force. An insertion rod 2102 is fixedly connected to the inside of the extrusion spring 2104, which plays a role in locking the socket 1 2105. The end of the extrusion spring 2104 close to the mounting box 9 is fixedly connected to a limiting block 2103, which plays a role in preventing the extrusion spring 2104 from falling off. A second plug hole 2106 is provided on the opposite side of the outside of the installation box 9, and a first plug hole 2105 is provided on the opposite side of the outside of the limit plate 10.

Four support columns 22 are fixedly connected to the bottom end of the installation box 9 to support the upper structure. The bottom ends of the four support columns 22 are all provided with anti-slip pads.

[0035] Working principle: before the mixing operation begins, first pull out the engaging mechanism 21 on both sides of the bottom of the installation box 9, push the plug rod 2102, and release the engagement between the plug rod 2102 and the socket 1 2105 by the resilience of the extrusion spring 2104, loosen the limit plate 10, and wait for the limit plate 10 to push the mixing barrel 1 back to the initial position by the resilience of the reset spring 11. When the operation begins, the corresponding raw materials are respectively put into the dry hopper 19 and the wet hopper 20, and the raw materials fall into the bottom of the mixing barrel 1 through the feed pipe 18. When the materials fall, the overall weight of the mixing barrel 1 will be increased. Under the elastic force of the reset spring 11, the limit plate 10 will slowly fall together with the mixing barrel 1.

Align the locking mechanism 21 with the second socket 2106, push the plug 2102, and make the plug 2102 pass through the second socket 2106 and lock with the first socket 2105 through the thrust of the extrusion spring 2104, fix the position of the limit plate 10, so that the overall structure of the mixing barrel 1 is stable during the operation, start the motor 3, and stir the material through the stirring shaft 4, the stirring rod 5, and the stirring blade 6. After the stirring is completed, turn off the motor 3, open the discharge valve 8, and connect the prepared storage device to the discharge pipe 7 for discharge. After the discharge is completed, unfasten the locking state of the plug 2102 and the first socket 2105, and start the motor 3 at the same time. When the mixing barrel 1 slowly rises, the motor 3 drives the stirring shaft 4 to rotate the stirring mechanism. At this time, the overall stirring mechanism will shake up and down in the mixing barrel 1. During the shaking process, the residual material on the inner wall of the mixing barrel 1 will fall off, and the material can be discharged through the discharge pipe 7 under the aggregation and contraction of the scraper 23, and then the motor 3 can be turned off to complete the operation.
