Description

Technical Field

[0001] The invention relates to the technical field of plant dye extraction devices, in particular to a plant dye raw material extraction device and process for textiles. Background Art

[0002] my country is a country with a large textile industry. The synthetic chemical dyes and auxiliaries used in textile dyeing and processing contain various harmful substances to varying degrees, which endanger people's health. In particular, the large amount of wastewater generated during the synthesis and processing of chemical dyes is difficult and expensive to treat, which puts great pressure on the ecological environment. Natural plant dyes have won the favor of the world with their natural environmental protection, green health, antibacterial and antibacterial, and easy degradation. As a result, natural plant dyes are increasingly used. Plant dyes are obtained from the roots, leaves, trunks or fruits of plants.

[0003] There are many methods for extracting plant dye raw materials, including immersion method, ultrasonic extraction method and microwave extraction method. Among them, immersion method is a more commonly used extraction method. The immersion method is to immerse the plant raw materials in a container filled with solvent to dissolve the dye components into the solvent, thereby achieving extraction. The immersion method is simple to operate, low-cost, and suitable for large-scale production.

[0004] In the current impregnation method, before impregnating the plant raw materials, the plant raw materials are first processed into smaller sections and placed in an impregnation container. In order to make the plant raw materials fully contact with the solvent, a stirring structure is usually provided to stir the mixture in the container to improve the extraction efficiency. However, the spacing of the current stirring blades is fixed. As the plant raw materials are stirred, the plant raw materials will become more fragmented. At this time, the stirring blades with the original dilution will be difficult to further fragment, resulting in poor effect in the later stage of impregnation. If a relatively dense stirring blade is set in the initial stage, this will increase the cutting resistance during the initial stirring, resulting in an increase in motor load and power consumption. In addition, the initial plant raw materials are squeezed between the relatively dense blades, which easily increases the interaction between the blades, resulting in increased blade wear and shortening the service life of the blades. Secondly, after the plant raw materials have absorbed enough, it is difficult to absorb them again, and the impregnation effect will deteriorate. For this reason, we propose a device and process for extracting plant dye raw materials for textiles. Summary of the invention

[0005] A technical problem to be solved by the present application is that the spacing between existing stirring blades is fixed. As the plant raw materials are stirred, the plant raw materials will become more fragmented. At this time, the stirring blades with the original diluteness will find it difficult to further perform the fragmentation operation.

[0013] In some embodiments, the fixing block is provided with a groove along the length direction, a spring is connected in the groove, and a second connecting rod is connected between the spring and the squeezing ball.

A rotatable connecting shaft 22 is provided in the tank body 1, and a plurality of stirring blades 8 are provided on the outside of the connecting shaft 22. One end of the stirring blade 8 is a cutting edge and the other end is a blunt portion. When the direction of rotation is such that the cutting edge contacts the plant material, the plant material can be further chopped during the stirring process to improve the impregnation effect. When the direction of rotation is such that the blunt portion contacts the plant material, it acts more as a stirring action without further chopping. The stirring blade 8 includes a movable blade 81 and a fixed blade 82. A plurality of circumferential surfaces for mounting the stirring blade 8 are provided along the length direction of the connecting shaft 22, and preferably a total of six movable blades 81 and fixed blades 82 on the same circumference are provided. The six stirring blades 8 are distributed in a circular array, and there are three movable blades 81 and three fixed blades 82, and the movable blades 81 and the fixed blades 82 are alternately distributed. The driving assembly 4 is used to drive the movable blade 81 to move laterally so that the movable blade 81 faces the area between the two lateral fixed blades 82. At this time, the space between the lateral stirring blades 8 becomes smaller, which can improve the stirring effect.

The diameters of the first connecting shaft 221 and the second connecting shaft 222 are both smaller than the diameter of the hollow cylinder 223. The hollow cylinder 223 is connected to the first connecting shaft 221. A connecting cylinder 7 is connected between the hollow cylinder 223 and the second connecting shaft 222. The end of the second connecting shaft 222 away from the connecting cylinder 7 can be detachably connected to the bearing seat on the inner wall of the tank door. After the tank door is installed, the end of the second connecting shaft 222 can be embedded in the bearing seat. The outer end of the first connecting shaft 221 is installed with the first motor 21, and the fixed blade 82 is fixed to the outer wall of the hollow cylinder 223.

[0021] See also Figure 7 As shown, the outer wall of the hollow cylinder 223 is provided with a through slot 12 along the length direction, and the through slot 12 is located between two adjacent rows of fixed blades 82. The mounting end of the movable blade 81 passes through the through slot 12. There are three movable blades 81 on the same circumferential surface, so that there are also three through slots 12 correspondingly.

[0023] See also Figure 6 As shown, the drive assembly 4 includes a screw 10, which is rotatably installed inside the hollow cylinder 223, and a plurality of screw nut seats 11 are provided outside the screw 10. The plurality of screw nut seats 11 can realize synchronous movement according to the screw 10, and the outer wall of the screw nut seat 11 is fixed with a plurality of connecting protrusions 111 in a circular array for connecting the mounting end of the movable blade 81.

[0024] In the specific implementation of the present invention, refer to Figure 5 and Figure 6 As shown, the drive assembly 4 also includes a second motor 41 and a second bevel gear 46. The second bevel gear 46 is installed at the end of the screw 10. The second motor 41 is installed at the top end of the outside of the horizontal tank body 1, and the output end of the second motor 41 is connected to a first connecting rod 44 extending to the through opening 73. The bottom end of the first connecting rod 44 is installed with a first bevel gear 45 in the mounting groove 72. The first bevel gear 45 can be meshed with the second bevel gear 46. After the second motor 41 is started, it can drive the first connecting rod 44 to rotate, which can drive the meshing first bevel gear 45 and second bevel gear 46 to rotate, so that the screw nut seat 11 outside the screw 10 moves to adjust the position of the movable blade 81.

[0025] In addition, a telescopic member 42 is installed on the outer wall of the horizontal tank body 1 through a mounting plate, a support plate 43 is provided at the bottom end of the second motor 41, and the top end of the telescopic member 42 is connected to the lower end surface of the support plate 43.

Specifically, the plant dye raw material extraction device for textiles also includes a pressing component 9, which is arranged at the end of the blunt part of the mixing and cutting blade 8. The pressing component 9 is used to press the plant material that absorbs the solvent along the rotating path when the rotating component 2 drives the mixing and cutting blade 8 to mix the plant material, so that the plant material can continue to absorb the solvent, which is more convenient for fully extracting the plant dye.

[0028] In the specific implementation mode, see Fig. 9 and Fig.10 As shown, the pressing assembly 9 includes a fixing block 91 fixed to the blunt portion of the mixing and cutting blade 8, and a lifting and lowering squeezing ball 93 is provided on the fixing block 91, and the squeezing ball 93 is hollow.

[0030] Through the above, during the chopping process of the chopping blade 8, the squeezing ball 93 can be pressed against the plant raw material, and can squeeze the plant raw material that absorbs too much solvent, so that the plant dye and the solvent are squeezed out together. Then the plant raw material can absorb the solvent again, and the solvent can be further used to absorb the plant dye in the plant raw material, which can effectively improve the extraction effect of the plant dye.

[0031] The expansion and contraction of the squeezing ball 93 connected by the second connecting rod 92 can be adjusted by utilizing the elastic effect of the spring 94 in the groove 95, so as to facilitate adjustment according to the stacking thickness of the plant raw materials.

[0032] A process for extracting plant dye raw materials for textiles, using the above-mentioned plant dye raw material extraction device for textiles, comprises the following steps: S1, adding the pretreated plant raw material from the feeding hopper 5 into the horizontal tank body 1, and adding the extraction solvent into the horizontal tank body 1, and then closing the hopper cover to immerse the plant raw material in the solvent; S2, initially making the movable blade 81 and the fixed blade 82 on the same circumferential surface on the same surface, starting the first motor 21, and using the first motor 21 to drive the first connecting shaft 221 to rotate, thereby driving the hollow cylinder 223 to rotate, thereby driving the multiple stirring and chopping blades 8 to stir and further chop the raw materials; S3, after the chopping blade 8 has been chopping for a period of time, the telescopic member 42 can be started, and the second motor 41 can be lowered by using the telescopic member 42, so that the first bevel gear 45 is meshed and connected to the second bevel gear 46, and then the second motor 41 is started, and the output end of the second motor 41 is used to drive the first connecting rod 44 equipped with the first bevel gear 45 to rotate, thereby driving the meshed second bevel gear 46 to rotate, so that the lead screw 10 in the hollow cylinder 223 is rotated, and the movable blade 81 can be moved out along the length direction to reduce the space in the length direction for accommodating the passage of plant materials; S4, during the chopping process of the chopping blade 8, the squeezing ball 93 is used to synchronously squeeze the plant material that has absorbed the solvent, and when the local plant material is too thick, the elastic effect of the spring 94 is used to adjust the expansion and contraction of the squeezing ball 93; S5. When there is no need to further chop the plant material in the late stage of soaking, the first motor 21 can be operated in reverse so that the blunt part of the stirring blade 8 contacts the plant material for stirring; S6. After the immersion is completed, the valve on the drain pipe 6 is opened to discharge and collect the extract in the horizontal tank body 1 from the drain pipe 6.
