Description

Technical field:

[0001] The present application relates to the technical field of pigment drying, and in particular to a phthalocyanine blue pigment processing and drying device. Background technology:

[0002] Phthalocyanine blue is mainly used for coloring automotive paints and art pigments. With the continuous improvement of people's living standards, the demand for phthalocyanine blue is increasing, and the requirements for its quality are also getting higher and higher.

[0003] Drying is a crucial step in the production of phthalocyanine blue. Currently, the phthalocyanine blue filter cake is typically dried directly in a drying oven. However, due to the large volume of the filter cake, heat and drying media (such as hot air) take a long time to penetrate the interior of the filter cake. Furthermore, the path for internal moisture to diffuse outward is long, resulting in slow, uneven, and incomplete drying, significantly reducing drying efficiency. Utility model content:

[0004] In order to solve the above technical problems, the present invention provides a phthalocyanine blue pigment processing and drying device, which solves the technical problem that the drying efficiency is reduced due to the large volume of the filter cake. In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A phthalocyanine blue pigment processing and drying device, comprising:

[0006] conveyors;

[0007] Gantry: two gantries are respectively arranged on the upper end surface of the conveyor in a fixed structure manner;

[0008] Squeeze roller, the squeeze roller is connected to the gantry at the front end in a rotating structure;

[0009] The cutting roller is connected to the gantry at the rear end in a rotating structure. The outer surface of the cutting roller is provided with a number of fixed-interval fan-shaped cutters along the circumferential direction. The fan-shaped cutters are evenly spaced along the axial direction. The outer surface of the cutting roller is also provided with evenly spaced transverse cutters along the axial direction. The lowest points of the fan-shaped cutters and the transverse cutters are in contact with the upper end surface of the conveyor.

[0010] A power device that drives the squeezing roller and the cutting roller to rotate, and the power device is connected to one side of the gantry in a fixed structure;

[0011] The unloading structure has one end connected to the bottom of the conveyor outlet in a fixed structure.

[0012] The drum dryer is arranged on one side of the conveyor, and the other end of the unloading structure extends obliquely downward into the interior of the drum dryer.

[0013] Furthermore, two pads are provided under the conveyor belt of the conveyor in a fixed structure, and the pads are respectively located under the squeezing roller and the cutting roller.

[0014] Furthermore, the unloading structure includes a Y-shaped bottom plate, the upper end of which is connected to the bottom of the conveyor outlet in a fixed structure manner, and the lower end extends into the drum of the drum dryer. Baffles are arranged on both sides of the Y-shaped bottom plate in a fixed structure manner.

[0015] Furthermore, the power device is a servo motor.

[0016] The beneficial effects of the utility model are:

[0017] 1. The phthalocyanine blue filter cake is processed before the pigment is dried. The squeezing roller is set to reduce the thickness of the filter cake, shortening the path for heat and drying medium to penetrate into the interior and the internal moisture to diffuse outward. The cutting roller is set to cut the filter cake into small pieces, increasing the surface area of ​​the filter cake in contact with hot air and improving the drying rate of the filter cake. The combination of the two facilitates the subsequent improvement of the filter cake drying efficiency.

[0018] 2. Set up a feeding structure and use gravity to introduce the filter cake dropped from the end of the conveyor directly into the drum dryer for drying, thereby speeding up the transmission speed between the conveyor and the drum dryer. Description of the drawings:

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will now be described in further detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0025] A phthalocyanine blue pigment processing and drying device includes a conveyor 1. Two gantries 4 are provided on the upper end face of the conveyor 1 in a fixed structure manner. The gantries 4 are connected in sequence with an extrusion roller 2 and a cutting roller 3 in a rotating structure manner. The outer surface of the cutting roller 3 is provided with a plurality of fixed-interval fan-shaped cutters 8 along the circumferential direction. The fan-shaped cutters 8 are evenly spaced along the axial direction. The outer surface of the cutting roller 3 is provided with transverse cutters 9 evenly spaced along the axial direction. The lowest points of the fan-shaped cutters 8 and the transverse cutters 9 are in contact with the upper end face of the conveyor 1. The fan-shaped cutters 8 and the transverse cutters 9 are staggered and used to cut the filter cake into small pieces; one side of the gantry 4 is connected to a power device in a fixed structure manner, and the power device is used to drive the extrusion roller 2 and the cutting roller 3 to rotate; a drum dryer 5 is provided at one end of the conveyor 1 outlet; a feeding structure is provided between the drum dryer 5 and the conveyor 1, one end of the feeding structure is connected to the lower part of the conveyor 1 outlet in a fixed structure manner, and the other end extends obliquely downward into the drum of the drum dryer 5.

[0026] Furthermore, the phthalocyanine blue filter cake is processed before the pigment is dried. By setting the squeezing roller 2, the thickness of the filter cake is reduced, shortening the path for heat and drying medium to penetrate into the interior and the internal moisture to diffuse outward; by setting the cutting roller 3, the surface area of ​​the filter cake in contact with hot air is increased, thereby improving the drying rate of the filter cake; the combination of the two facilitates the subsequent improvement of the drying efficiency of the filter cake.

[0027] Specifically, two pads 6 are arranged in a fixed structure under the conveyor belt of the conveyor 1, and the pads 6 are respectively located under the squeezing roller 2 and the cutting roller 3; they provide support when the squeezing roller 2 and the cutting roller 3 process the filter cake, thereby preventing the filter cake from moving downward due to the soft belt during the processing, and failing to achieve the expected processing effect.

[0028] It should be noted that the unloading structure includes a Y-shaped bottom plate 7, the upper end of the Y-shaped bottom plate 7 is connected to the bottom of the outlet of the conveyor 1 in a fixed structure manner, and the lower end extends into the drum of the drum dryer 5. Baffles 11 are provided on both sides of the Y-shaped bottom plate 7 in a fixed structure manner to prevent the filter cake from sliding from both sides of the Y-shaped bottom plate 7 and causing waste; by utilizing the action of gravity, the filter cake falling from the end of the conveyor 1 is directly introduced into the drum dryer 5 for drying, thereby ensuring the transmission speed of the material between the conveyor 1 and the drum dryer 5.

[0029] It should be explained that the power device is a servo motor 10 .

[0030] The working principle and working process of this utility model are as follows:

[0031] Start the conveyor 1, servo motor 10 and drum dryer 1, the conveyor 1 starts to convey, and the squeezing roller 2 and cutting roller 3 start to rotate; then the filter cake is placed at the entrance of the conveyor 1, and the filter cake is conveyed along the conveyor 1. After being squeezed by the squeezing roller 2 and cut by the cutting roller 3, the filter cake becomes small blocks of filter cake with uniform thickness, and then is conveyed to the end of the conveyor 1 and falls onto the discharge structure, and slides from the discharge structure into the drum dryer 5 for drying.

[0032] After drying, the dried product is discharged from the outlet of the drum dryer 5 , which belongs to the prior art and will not be described in detail.
