Description

Technical Field

[0001] This utility model relates to a modification device for producing inorganic non-metallic modified powders with good dispersibility, belonging to the field of inorganic powder modification technology. Background Technology

[0002] Inorganic non-metallic resources are abundant, inexpensive, and have excellent performance. Commonly used inorganic non-metallic powders in industry include calcium carbonate, sulfuric acid, talc, wollastonite, and kaolin. They have been widely used in plastic products and have become important fillers, modifiers, and reinforcing materials, achieving significant economic, social, and ecological benefits.

[0003] However, inorganic non-metallic powders have inherently poor compatibility with organic polymers such as plastics, necessitating surface modification. However, during the modification process, high-speed stirring generates static electricity, causing powder particles to adsorb and agglomerate, resulting in coarse particles that affect the powder's performance. Furthermore, the waste heat generated during the modification process, after dust removal, is directly released into the air, leading to energy waste. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of static electricity and agglomeration in the traditional modification of inorganic non-metallic ultrafine powders, and to propose a modification device for producing inorganic non-metallic modified powders with good dispersibility.

[0005] The technical solution of this utility model is as follows: a modification device for producing inorganic non-metallic modified powder with good dispersibility, including a semi-finished product silo, a spiral cutter, an ion fan, a reagent tank, a cyclone separator, a pulse bag collector, an induced draft fan, a material drying room, a packaging machine, and a recycling powder silo, and also includes a three-roller modification main unit.

[0006] The three-roller modification machine consists of three triangular modification cylinders, each equipped with a rotor and a stator. When the dried powder and the precisely metered reagent enter the modification cylinder simultaneously, they move in a fluidized vortex motion as the rotor rotates at high speed. The surface modification is rapidly completed by the collision, friction, and shearing of the powder at high speed and the heat generated by the high-speed rotating rotor.

[0007] The bottom outlet of the semi-finished product silo is connected to the inlet of the three-roller modifier via a first spiral cutter; the outlet of the three-roller modifier is connected to a cyclone separator via a pipe; the top of the cyclone separator is connected to a pulse bag collector via a pipe, and the bottom outlet is connected to a recovery powder silo; the top outlet of the pulse bag collector is connected to the material drying chamber via an air duct and an induced draft fan, and the bottom outlet of the pulse bag collector is connected to a packaging machine via a second spiral cutter.

[0008] The modified host is equipped with a spray nozzle at its feed inlet; the spray nozzle is connected to both the ion fan and the reagent tank.

[0009] The logistics drying room can be used to dry crushed and cleaned inorganic non-metallic ores.

[0010] The beneficial effects of this invention are as follows: the three-roller modification host used in this invention rapidly completes surface modification through the high-speed operation of the rotor, powder collision, friction, shearing, and the heat generated by the high-speed rotation of the rotor, resulting in good modification effect; after modification by the three-roller modification host, the powder has less agglomeration and better dispersion performance after separation by the air separator; the ion fan ionizes the air to generate a large number of positive and negative charges, which can neutralize the charges carried on the surface of the powder during high-speed friction, collision, and shearing, thus achieving destatic treatment of the powder; this invention can be continuously produced with high output and low energy consumption; it can be fully utilized and conforms to green development, energy conservation and environmental protection.

[0015] In this embodiment, the semi-finished product hopper 1 feeds inorganic non-metallic powder into the three-roller modification host 6 through the first spiral cutter 2.

[0016] The modification host 6 in this embodiment consists of three triangular modification cylinders. Each modification cylinder contains a rotor and a stator, dried powder and precisely metered reagent. When they enter the modification cylinder simultaneously, they move in a fluidized vortex with the high-speed rotation of the rotor.

The modification host 6 is provided with a spray nozzle 5 at the feed inlet. The spray nozzle 5 is connected to the ion fan 3 and the reagent tank 4.

[0017] In this embodiment, the ion fan 3 ionizes the air to generate a large number of positive and negative charges and blows the positive and negative charges out with the fan, forming an airflow of positive and negative charges. This airflow can neutralize the charges on the surface of the powder during high-speed friction, collision and shearing, and at the same time carry the modifier into the modifier host 6.

[0020] The logistics drying room 13 in this embodiment can be used to dry inorganic non-metallic ores after crushing and cleaning. Inorganic non-metallic ores need to be crushed, cleaned, selected, and naturally dried after being mined from the mining area.

[0021] The process flow of this embodiment is as follows: Inorganic non-metallic powder in the semi-finished product silo 1 is conveyed to the modification host 6 through the first spiral cutter 2; at the same time, the ion fan 3 blows the positive and negative charged airflow and the modifier into the modification host 6 together; with the high-speed rotation of the rotor, it runs in a fluidized vortex, and the surface modification is quickly completed by the collision, friction, shearing of the powder at high speed and the heat generated by the high-speed rotating rotor. Under the action of the induced draft fan 9, the inorganic non-metallic fine powder enters the pulse bag collector 8 through the cyclone separator 7 for collection and packaging, and is sent to the packaging machine 12; the coarse particles are separated by the cyclone separator 7 and enter the recycling powder silo 10 for recycling from the discharge port at the bottom of the cyclone separator 7; the heat generated by the powder during the modification process is conveyed to the material drying room 13 by the induced draft fan 9 to dry the minerals.
