Problems solved by technology

[0003] Since the calcium carbonate powder is easy to absorb moisture and agglomerate after being placed for a long time, the calcium carbonate powder cannot be used directly and must be dried. , the drying time is long, and the agglomerated calcium carbonate powder is not easy to disperse, which not only leads to a longer drying time, but also requires more heat energy to be used during drying, which is not conducive to environmental protection
[0004] In actual production, it is generally stirred and turned manually to disperse the agglomerated calcium carbonate, and then dry it. Manual treatment not only slows down the efficiency, but also increases the production cost, which is of great importance to the development of the enterprise. Unfavorable, how to disperse the calcium carbonate powder that is agglomerated by moisture is the problem we solve

Embodiment 1

[0036] see figure 1 In the present invention, the dispersing device includes a feed plate 1, a casing 2 and a centrifugal device. The feed plate 1 is in the shape of a funnel with a large upper part and a smaller bottom. It is connected with the lower end of the material guide plate 1, the upper end of the material guide plate 1 is the material inlet 101, and the lower end of the shell 2 is the material outlet 201, and the centrifugal device is installed in the shell 2, and the centrifugal device includes a centrifugal disc I3, a centrifugal disc II4, a rotating shaft 5 and a shaft sleeve 6. The centrifugal disc I3 is located above the centrifugal disc II4. The centrifugal disc I3 is connected to the rotating shaft 5, and the centrifugal disc II4 is connected to the shaft sleeve 6. The rotating shaft 5 passes through the shaft sleeve 6 and enables the rotating shaft 5 and the shaft sleeve 6 to rotate independently of each other. The shaft sleeve 6 is fixed on the inner wall of...

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, except that the transmission device is a belt transmission device, and the principle of the belt transmission device is basically the same as that of the gear transmission device. Drive pulley, then connect drive pulley on motor 8, be connected by belt between drive pulley and driven pulley.

Embodiment 3

[0046] This embodiment is basically the same as Embodiment 2, except that the transmission device is a chain transmission device, that is, the driving sprocket is connected to the rotating shaft 5 and the shaft sleeve 6, and then the driven sprocket is set on the motor 8 , the driving sprocket and the driven sprocket are connected by a chain.

[0047] Wherein, the direction of the arrow in the accompanying drawing is the path direction of calcium carbonate powder and agglomeration in the dispersion process.

Abstract

The invention discloses a calcium carbonate powder dispersing method. The calcium carbonate powder dispersing method is characterized by particularly comprising the following steps: 1, throwing calcium carbonate powder with blocks into a dispersing device, wherein the dispersing device comprises a shell and a centrifugal device, and the centrifugal device comprises a centrifugal disk I, a centrifugal disk II, a rotating shaft and a shaft sleeve; 2, colliding the blocks with the centrifugal disk I to realize collision and dispersion for the first time; 3, dispersing to the periphery through thecentrifugal effect of the centrifugal disk I and colliding with the inner wall of the shell to realize collision and dispersion for the second time; 4, colliding the blocks with the centrifugal diskII to realize collision and dispersion for the third time; and 5, dispersing to the periphery through the centrifugal effect of the centrifugal disk II and colliding with the inner wall of the shell to realize collision and dispersion for the fourth time, and discharging after collision and dispersion for many times. By the calcium carbonate powder dispersing method, the agglomerated calcium carbonate powder can be dispersed rapidly; and the calcium carbonate powder dispersing method has the advantages of high efficiency and good dispersing effect.

Description

technical field [0001] The invention relates to a method for dispersing powder agglomerates, in particular to a method for dispersing calcium carbonate powder. Background technique [0002] Calcium carbonate is an inorganic compound, commonly known as limestone, limestone, stone powder, marble, calcite, is a compound, the chemical formula is CaCO 3 , Neutral, basically insoluble in water, soluble in acid. It is a common substance on earth and exists in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of animal bones or shells. Calcium carbonate is an important building material, widely used in industry, and also a common reagent in middle and high school chemistry (commonly used to react with hydrochloric acid to generate CO 2 Wait). [0003] Since the calcium carbonate powder is easy to absorb moisture and agglomerate after being placed for a long time, the calcium carbonate powder cannot be used directly and must...
