Description

Technical Field

[0001] The invention relates to the technical field of talc processing equipment, in particular to a talc cake making process and a production device thereof. Background Art

[0002] Talc is a hydrothermal alteration mineral. Magnesium-rich minerals often become talc after hydrothermal alteration, so talc often appears as minerals such as olivine, enstatite, hornblende, tremolite, etc. Talc is a common silicate mineral. It is very soft and has a slippery feel. People have selected 10 minerals to represent 10 hardness levels, called Mohs hardness. Among these 10 levels, the first one is talc. Soft talc can replace chalk to draw white marks. Talc is generally in block, leaf, fibrous or radial shape, white, grayish white, and may have various colors due to other impurities. Talc has many uses, such as refractory materials, papermaking, rubber fillers, insulating materials, lubricants, pesticide absorbents, leather coatings, cosmetic materials and carving materials, etc.

By introducing high-pressure hot air into the air inlet port, the high-pressure hot air enters the filter body through the air inlet port and the bellows, and the high-pressure hot air entering the filter body can pass through the sieve holes on the outer surface of the filter body to dry the talc powder between the rubber inflatable airbag and the filter body.

Through the coordinated use of the fixing frame 2 and the fixing plate 3, it is convenient to provide support for the box body 4 and the sedimentation box 5, and to facilitate the connection between the box body 4 and the sedimentation box 5 and the chassis 1.

[0053] As a technical optimization solution of the present invention, the top of the sedimentation box 5 is respectively connected with a feed port 6 and a drug addition port 7.

[0054] As a technical optimization solution of the present invention, a plurality of mounting holes are provided in a ring shape on the top of the chassis 1. The plurality of mounting holes on the top of the chassis 1 can facilitate the installation of the chassis 1, and further facilitate the installation of the device.

[0055] When the present invention is used, when it is necessary to make cakes of talc slurry, first, the talc slurry raw material is introduced into the sedimentation box 5 through the feed port 6, and the flocculant is introduced into the sedimentation box 5 through the dosing port 7. At this time, the talc slurry raw material will react with the flocculant in the sedimentation box 5. Adding polyacrylamide flocculant to the talc slurry raw material can effectively increase the sedimentation rate of talc particles in the talc slurry raw material, and at the same time, the fine particles in the talc slurry raw material are deposited together to reduce waste.

[0056] The talc slurry raw material is reacted with the flocculant in the sedimentation box 5 to sediment the talc slurry raw material. The talc slurry raw material will settle to the bottom wall of the sedimentation box 5 to form a layer of talc powder and water. At this time, the clear liquid in the upper layer is discharged through the drainage port 8 to separate the water in the talc slurry raw material from the talc slurry raw material. Most of the water in the talc slurry raw material after sedimentation can be removed to obtain talc powder.

[0057] After the talc slurry raw material has settled in the sedimentation box 5, the electronic valve in the discharge port 24 is opened, and the talc powder obtained after settling in the sedimentation box 5 can fall into the box body 4 through the discharge port 24, and the talc powder is located between the rubber inflatable airbag 23 and the filter body 22.

[0058] At this time, the first water pump 18 is started, and the first water pump 18 can pump the water in the water tank 16 into the first delivery pipe 17. The water entering the first delivery pipe 17 can enter the rubber inflatable airbag 23. After the water enters the rubber inflatable airbag 23, a collision occurs, and the box body 4 restricts the rubber inflatable airbag 23. Then, the rubber inflatable airbag 23 collides with the filter body 22, and the talcum powder is between the rubber inflatable airbag 23 and the filter body 22. When the rubber inflatable airbag 23 collides, the talcum powder can be squeezed by the colliding rubber inflatable airbag 23, and the talcum powder is squeezed. After the talc powder is squeezed by the rubber inflatable airbag 23 and the filter body 22, the moisture in the talc powder can be squeezed into the filter body 22 through the sieve holes on the outer surface of the filter body 22, and then the moisture in the talc powder is squeezed out again, and the water entering the filter body 22 through the sieve holes on the outer surface of the filter body 22 can flow downward under the action of gravity, and drip into the collection box 14 through the collection hole 25, and the water entering the collection box 14 can be discharged through the water outlet pipe 15. At this time, high-pressure hot air is introduced into the air inlet port 9, and the high-pressure hot air is passed through the air inlet port 9. The high-pressure hot air enters the filter body 22 through the air inlet port 9 and the bellows 21, and the high-pressure hot air entering the filter body 22 can dry the talc powder between the rubber inflatable airbag 23 and the filter body 22 through the sieve holes on the outer surface of the filter body 22. The talc powder between the rubber inflatable airbag 23 and the filter body 22 can be dried at high temperature to further remove the moisture in the talc powder, so as to complete the talc cake making process and obtain a talc cake. The annular filter body 22 is squeezed by the annular rubber inflatable airbag 23 to dry the talc powder between the rubber inflatable airbag 23 and the filter body 22. The talc powder between the rubber inflatable airbag 23 and the filter body 22 is squeezed, and the pressure zone area is greatly increased through the annular design of the rubber inflatable airbag 23 and the filter body 22, thereby improving the production efficiency. At the same time, the rubber inflatable airbag 23 is used to pass water to extrude and compress the filter body 22, thereby increasing the pressure of the rubber inflatable airbag 23, and the talc powder is squeezed more thoroughly. The overall cake making efficiency will be greatly improved. At the same time, the sieve holes of the filter body 22 are used to filter the water in the talc powder, eliminating the use of traditional filter cloth, and also meeting the filtering of fine powder slurry.

[0059] The rubber inflatable airbag 23 is expanded by water pressure, and the extrusion pressure can reach a higher level, the water extrusion effect is better, and the residual moisture can be discharged from the capillary moisture of the cake body by inputting high-pressure hot air into the filter body 22, so that a lower filter cake moisture can be achieved. In addition, through this device, the process of sedimentation, extrusion and drying is carried out in the same equipment, thereby saving costs and improving efficiency.

[0060] After the talcum powder is dried, the electric telescopic rod 11 is started, and the piston rod of the electric telescopic rod 11 is retracted to drive the collecting box 14 and the filter body 22 to move downward, and the filter body 22 can move downward through the circular opening 26 at the bottom of the box body 4 until the filter body 22 moves down to the bottom of the box body 4 and stops. At this time, the talcum powder between the rubber inflatable airbag 23 and the filter body 22 can fall downward through the circular opening 26 due to the downward movement of the filter body 22, and the dried talcum powder can be discharged into the receiving tray 10, which is convenient for unloading the dried talcum powder. In addition, by injecting water into the rubber inflatable airbag 23 again to reduce the inner diameter of the rubber inflatable airbag 23, the talcum powder is pushed, which can also assist the unloading of the talcum powder in the box body 4.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
