Description

Technical Field

[0001] The invention relates to the technical field of chemical production equipment, and in particular to an automated production line for white carbon black. Background Art

[0002] White carbon black is modified silicon dioxide, which is a general term for white powdered X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica and ultrafine silica gel, and also including powdered synthetic aluminum silicate and calcium silicate. White carbon black is a porous substance, and its composition can be expressed by SiO2·nH2O, where nH2O exists in the form of surface hydroxyl groups. It is soluble in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). It is resistant to high temperatures, non-flammable, tasteless, odorless, and has good electrical insulation. White carbon black is generally divided into precipitated white carbon black and fumed white carbon black according to the production method. The precipitation method is also called the wet method, which is to prepare white carbon black by reacting silicate with strong acid. The white carbon black prepared by the precipitation method has low purity, hydrophilic surface and large particles.

A plurality of fans 4 and washing spray devices 5 are provided, and the two are alternately arranged in the horizontal direction. The washing spray device 5 washes materials by spraying detergent, and the fan 4 generates wind to sweep the sprayed detergent so that the detergent is evenly dispersed. A mesh belt 7, a driving part and a rolling part are provided inside the shell 1, and a synchronous toothed belt 8 is provided on the mesh belt 7, and the synchronous toothed belt 8 is matched with the driving part in transmission.

[0033] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the driving part includes a first shell 9, and the first shell 9 is provided with a first driving member 10, a synchronous gear 11, a transmission mechanism and a vibration mechanism.

The first driving member 10 drives the synchronous gear 11 to rotate, and drives the synchronous toothed belt 8 to move. The first limiting roller 12 has a tensioning effect on the vertical part of the synchronous toothed belt 8. The mesh belt 7 and the horizontal part of the synchronous toothed belt 8 remain loose, and are driven by the vibration mechanism to vibrate up and down rapidly. The horizontal part of the mesh belt 7 forms a wave shape, and the material is thrown up with the vibration, so that the material is loose, so that the inside and outside of the accumulated material can be washed evenly. The driving rod 19 is driven to rotate by the transmission mechanism, and further through the transmission rod 20, the guide rod 17 is reciprocated with its own center as the center of the circle, thereby driving the support rod 13 to reciprocate up and down. The second limiting roller 15 has a limiting effect on the support rod 13, so that it can only move up and down. The first transmission gear 22 is large in size, so the rotation speed of the second transmission gear 23 is high, so that the vibration frequency of the vibration mechanism is high.

[0034] Specifically, Figure 2 , Figure 8 and Fig. 9As shown, the rolling part includes a second shell 26 and a driving mechanism. A roller 27 and a stirring shaft 28 are arranged inside the second shell 26. A lifting assembly is arranged at the end of the roller 27. A plurality of stirring rods 29 are arranged on the periphery of the stirring shaft 28. The lifting assembly includes a fixed plate 34 and a lifting plate 35. A threaded rod 36 is arranged through the lifting plate 35. The lifting plate 35 is rotatably connected with the threaded rod 36. The threaded rod 36 passes through the fixed plate 34. The threaded rod 36 is threadedly connected with the fixed plate 34. The fixed plate 34 is fixedly connected to the housing 1. A handle 37 is arranged at the upper end of the threaded rod 36. The driving mechanism includes a fourth transmission assembly 38, a second driving member 39 and an elastic assembly. The elastic assembly includes an elastic member 40, a connecting seat 41 and an extruding roller 42. A fixed seat 30 is arranged inside the second shell 26. A baffle 31 is slidably connected to the fixed seat 30. The baffle 31 is located above the roller 27. The lower end of the baffle 31 is in sliding contact with the periphery of the roller 27. The second driving member 39 can drive the roller 27 and the stirring shaft 28 to rotate through the fourth transmission assembly 38. The material moves into the second housing 26 along with the mesh belt 7. The material will accumulate in front of the roller 27 as it continues to enter. The stirring rod 29 can rotate to stir the accumulated material, so that the material is not easy to agglomerate. The material can pass through the bottom of the roller 27 to form a shallow layer. The threaded rod 36 can be rotated by the handle 37 to drive the roller 27 to move up and down, and the distance between the roller 27 and the mesh belt 7 can be adjusted, thereby changing the thickness of the extruded material.

[0035] Specifically, Figure 6 , Figure 7 , Fig. 9 As shown in FIG. 1 , the first transmission assembly 21 , the second transmission assembly 24 , the third transmission assembly 25 and the fourth transmission assembly 38 all include a transmission belt and two transmission wheels, and the transmission belt and the two transmission wheels are in rolling contact. The multiple transmission assemblies play a role in power transmission to ensure the normal operation of the device.

[0036] Specifically, Fig. 9 As shown, the two ends of the elastic member 40 are fixedly connected to the housing 1 and the connecting seat 41 respectively, the connecting seat 41 is rotatably connected to the squeezing roller 42, and the squeezing roller 42 is in rolling contact with the transmission belt of the fourth transmission assembly 38. After the roller 27 is adjusted up and down, the elastic member 40 makes the squeezing roller 42 always fit the transmission belt of the fourth transmission assembly 38 under the elastic force so that it is always kept taut, reducing slippage and allowing the power to be transmitted stably.

[0037] Specifically, Figure 2 , Figure 3 and Figure 8As shown, a feed slot 32 and a discharge slot 33 are respectively provided on both horizontal sides of the second shell 26. The height of the feed slot 32 is greater than that of the discharge slot 33. The material enters from the feed slot 32, is squeezed into a shallow layer, and then leaves from the discharge slot 33. A discharge hopper 43 is provided at the bottom of the shell 1, and a material trough 44 is provided below the discharge hopper 43. The mesh belt 7 is vibrated by a vibration mechanism, and part of the material stuck on the mesh belt 7 is shaken off and falls from the discharge hopper 43 into the material trough 44, which is convenient for centralized recovery.

[0038] In summary, the present embodiment provides an automated production line for white carbon black. When washing the material, the stirring shaft 28 rotates and the stirring rod 29 stirs the material, so that the material is not easy to clump. The material moves with the mesh belt 7 and passes under the roller 27 to form a shallow layer. Then, driven by the vibration component, the mesh belt 7 vibrates up and down rapidly to form a wave shape. During the vibration, the material is thrown up to keep the material loose, and the detergent is evenly sprayed on the material through the fan 4 and the washing spray device 5.
