Description

Technical Field

[0001] This utility model relates to the technical field of mechanical activation devices for calcium carbonate, and more specifically, to mechanical activation equipment for processing heavy calcium carbonate with nano-modification. Background Technology

[0002] Calcium carbonate is an inorganic compound that is neutral, practically insoluble in water but soluble in hydrochloric acid. It is one of the most common substances on Earth, and activated calcium carbonate, as a high-grade filler with high filler content, is widely used in many industries.

[0003] Currently, mechanical activation equipment for calcium carbonate processing has poor mixing efficiency when activating calcium carbonate powder, and it is easy to cause accumulation when adding it, which reduces the working efficiency. For example, CN 221045903U discloses an activation machine for processing activated calcium carbonate, which includes a machine body, a support pile at the lower end of the machine body, an arc-shaped bottom of the machine body, a feed trough on the right inner wall near the top of the machine body, an exhaust pipe and a discharge pipe on the left inner wall and bottom of the machine body, respectively, and a cover fixedly connected to the upper end of the machine body. A drive mechanism is penetrated through the top surface of the center of the cover.

[0004] As can be seen from the above-disclosed scheme, when calcium carbonate powder and modifier are added through the feed tank, the activation machine is prone to causing the calcium carbonate powder and modifier to accumulate in the machine body, thereby increasing the mixing time. In addition, the contact area between the arc-shaped stirring plate and the calcium carbonate powder and modifier is small, which reduces the segmentation area, reduces the radial stirring effect of the calcium carbonate powder and modifier, and thus reduces the mixing efficiency. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a mechanical activation device for processing mechanically activated nano-modified heavy calcium carbonate. This mechanical activation device, through the setting of a filter box and filter screen, can filter out large particulate impurities inside the calcium carbonate powder and modifier during addition, and can prevent the accumulation of calcium carbonate powder and modifier during addition. Furthermore, through the setting of scraper and multiple inclined stirring blades, not only is radial stirring of calcium carbonate powder and modifier facilitated, but the inclined stirring blades and surface pores can also increase the separation area of ​​calcium carbonate powder and modifier, thereby improving mixing efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A mechanical activation device for processing nano-modified heavy calcium carbonate includes a main body. The bottom of the main body has a discharge port and support legs. An end cap is fastened to the top of the main body, and a feeding hopper is fixedly connected to the surface of the end cap. A filter mechanism is movably connected to the bottom of the end cap, and a stirring mechanism is fixedly connected to the bottom of the filter mechanism. The stirring mechanism includes a motor, one end of which is fixed to the middle of the bottom of the main body. A rotating shaft is fixedly connected to the output end of the motor, and a stirring assembly is fixedly connected to the surface of the rotating shaft. This mechanical activation device for processing nano-modified heavy calcium carbonate can filter large particulate impurities during the addition of calcium carbonate powder and modifiers through the filter box and filter screen, preventing accumulation of calcium carbonate powder and modifiers. Furthermore, the scraper and multiple inclined stirring blades not only facilitate radial stirring of the calcium carbonate powder and modifiers, but the inclined stirring blades and surface pores also increase the separation area of ​​the calcium carbonate powder and modifiers, thereby improving mixing efficiency.

[0008] Furthermore, the stirring assembly includes a scraper and a spiral blade. The surfaces of the scraper and the spiral blade are fixedly connected to the surface of the rotating shaft. Multiple stirring blades are fixedly connected to the surface of the scraper. The stirring blades are inclined. The spiral blades can tumble the calcium carbonate powder and the modifier up and down. The inclined stirring blades can increase the radial stirring effect of the calcium carbonate powder and the modifier.

[0009] Furthermore, the filtration mechanism includes a filter box, the inner wall of which is fixedly connected to a reinforcing plate. The reinforcing plate and the inner wall of the filter box together form an installation hole, and the inner wall of the installation hole is fixedly connected to a filter screen. The filter screen can intercept large particulate impurities in the calcium carbonate powder and modifier, and at the same time, it can be thrown downwards through the mesh and centrifugal force, thereby improving the uniformity of feeding.

[0010] Furthermore, a connecting cover is fixedly connected to one end of the reinforcing plate. The outer side of the connecting cover is fixedly connected to the end face of the filter screen. A connecting hole is opened at the bottom of the connecting cover. The connecting hole is polygonal, and the inner wall of the connecting hole is fixedly connected to the surface of the rotating shaft, so that the rotating shaft can drive the filter box to rotate.

[0011] Furthermore, the surface of the scraper is provided with a positioning groove, which is inclined and fixedly connected to one end of the stirring blade. The positioning groove facilitates the pre-positioning of the stirring blade and increases the connection strength.

[0012] Furthermore, an anti-wear pad is fixedly connected to the open end of the filter box. The surface of the anti-wear pad is slidably connected to the inner wall of the end cap. The anti-wear pad can prevent wear between the filter box and the end cap, and at the same time, it can seal the opening of the filter box.

[0013] Furthermore, the surface of the stirring blade has equally spaced dividing holes. When the stirring blade rotates, the dividing holes divide the stirred calcium carbonate powder and modifier, accelerating their mixing.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can filter out large particulate impurities inside calcium carbonate powder and modifier when they are added by setting filter boxes and filter screens, and at the same time avoids accumulation of calcium carbonate powder and modifier when they are added.

[0016] (2) The present solution uses scrapers and multiple inclined stirring blades to facilitate radial stirring of calcium carbonate powder and modifier. The inclined stirring blades and surface holes can increase the separation area of ​​calcium carbonate powder and modifier, thereby improving the mixing efficiency. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5 Mechanical activation equipment for processing heavy calcium carbonate with nano-modification includes a mechanical activation equipment body 1. The mechanical activation equipment body 1 modifies the surface of the calcium carbonate powder by mixing it with a modifier, thereby performing surface activation coupling treatment to reduce the surface tension of the inorganic particles. The bottom of the mechanical activation equipment body 1 is provided with a discharge port and support legs 13. A sealing door is slidably connected to the bottom of the discharge port for easy opening and closing. After the discharge port is opened, a scraper 34 rotates to accelerate the discharge. An end cap 11 is fastened to the top of the mechanical activation equipment body 1. A feeding hopper 12 is fixedly connected to the surface of the end cap 11. A filter mechanism 2 is movably connected to the bottom of the end cap 11, and a stirring mechanism 3 is fixedly connected to the bottom of the filter mechanism 2. The stirring mechanism 3 includes a motor 31. One end of the motor 31 is fixed to the middle of the bottom of the mechanical activation device body 1. The output end of the motor 31 is fixedly connected to a rotating shaft 32. A stirring assembly is fixedly connected to the surface of the rotating shaft 32. The stirring assembly includes a scraper 34 and a spiral blade 33. The surfaces of the scraper 34 and the spiral blade 33 are fixedly connected to the surface of the rotating shaft 32. Multiple stirring blades 36 are fixedly connected to the surface of the scraper 34. The stirring blades 36 are inclined. The spiral blades 33 can flip the calcium carbonate powder and the modifier up and down. The top of the inclined stirring blades 36 is fixedly connected to the bottom of the filter box 21 and the reinforcing plate 25, ensuring its connection is firm and increasing the radial stirring effect of the calcium carbonate powder and the modifier.

[0027] The filtration mechanism 2 includes a filter box 21. A reinforcing plate 25 is fixedly connected to the inner wall of the filter box 21. The reinforcing plate 25 and the inner wall of the filter box 21 enclose an installation hole 26. A filter screen 22 is fixedly connected to the inner wall of the installation hole 26. The filter screen 22 can intercept large particulate impurities in the calcium carbonate powder and modifier. At the same time, it can be thrown downward by the mesh and centrifugal force, which improves the uniformity of feeding. A connecting cover 23 is fixedly connected to one end of the reinforcing plate 25. The outer side of the connecting cover 23 is fixedly connected to the end face of the filter screen 22. A connecting hole 24 is opened at the bottom of the connecting cover 23. The connecting hole 24 is polygonal. The inner wall of the connecting hole 24 is fixedly connected to the surface of the rotating shaft 32, so that the rotating shaft 32 can drive the filter box 21 to rotate. The surface of the stirring blade 36 has equally spaced dividing holes. When the stirring blade 36 rotates, the dividing holes divide the stirred calcium carbonate powder and modifier, accelerating the mixing of the two.

[0028] The surface of the scraper 34 has a positioning groove 35, which is inclined. The positioning groove 35 is fixedly connected to one end of the stirring blade 36. The positioning groove 35 facilitates the pre-positioning of the stirring blade 36 and increases the connection strength. The open end of the filter box 21 is fixedly connected to an anti-wear pad 27. The surface of the anti-wear pad 27 is slidably connected to the inner wall of the end cover 11. The anti-wear pad 27 can prevent wear between the filter box 21 and the end cover 11 and can also seal the opening of the filter box 21.

[0029] When using the mechanical activation equipment for processing nano-modified heavy calcium carbonate, the motor 31 is started first. The operation of the motor 31 causes the rotating shaft 32 to drive the spiral blades 33, stirring blades 36, and filter box 21 to rotate. Then, calcium carbonate powder and modifier are added to the feeding hopper 12. The calcium carbonate powder and modifier in the feeding hopper 12 fall downward onto the surface of the connecting cover 23. At the same time, the rotating filter box 21 causes the added calcium carbonate powder and modifier to spread radially, while intercepting large particles of impurities inside. Then, the calcium carbonate powder and modifier are thrown downward through the filter holes into the interior of the mechanical activation equipment body 1 to avoid the material from piling up. At this time, the rotating spiral blades 33 and stirring blades 36 tumble the calcium carbonate powder and modifier up and down and radially, while accelerating the mixing of calcium carbonate powder and modifier through the separation holes.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
