Description

Technical Field

[0001] This utility model relates to the technical field of powder material mixing equipment, specifically a high-speed mixer for metering and preparing stone paper raw materials. Background Technology

[0002] Stone paper is a new type of environmentally friendly paper. Its raw materials are mainly inorganic minerals, with a small amount of polymer materials and other auxiliary materials. The inorganic mineral powder (core raw material) is mainly calcium carbonate (CaCO3), and may also contain mineral powders such as talc and kaolin. The proportion of mineral powders such as calcium carbonate is usually as high as 70%-80%, which is the "skeleton" of stone paper and gives the paper its basic physical form (such as hardness and stiffness). Utilizing its natural whiteness and opacity, it can replace plant fibers in traditional paper and reduce wood consumption.

[0003] Heating is required during the raw material mixing process of stone paper, which is usually carried out using a high-speed mixer. Although high-speed mixers are widely used in the pretreatment stage of stone paper raw materials, their structure and working principle also bring certain limitations. The agitator of the high-speed mixer is difficult to overcome the resistance of high-concentration powders, and "dead corners" such as the bottom or edge of the container are prone to material accumulation, resulting in uneven mixing of calcium carbonate and polymer, and even powder agglomeration. The heating method of the high-speed mixer is mainly frictional heat and external electric heating. The high-speed mixer mixes dust inside, so a sealing design is required. When the stirring speed or material quantity changes, if the temperature of the material inside the high-speed mixer becomes too high, the excess heat cannot be quickly discharged, causing polymer degradation or additive failure. In order to solve the above-mentioned problems, this application is submitted. Utility Model Content

[0014] Please see Figures 1-4 In this embodiment of the invention, a high-speed mixer for metering and preparing stone paper raw materials includes a raw material line 1, a weighing bin 2, a feeding line 3, and a high-speed mixer 4. The input end of the weighing bin 2 is connected to the raw material line 1, and the output end of the weighing bin 2 is connected to the high-speed mixer 4 via the feeding line 3. A filter 7 is connected to the top of the high-speed mixer 4, and the filter 7 is connected to a jacketed tank 10 via an air compressor 9. The jacketed tank 10 is connected to the bottom of the high-speed mixer 4 via a low-pressure pipeline 5. The air compressor 9 compresses air and sends it into the high-speed mixer 4 to blow up the accumulated material at the bottom of the high-speed mixer 4. The powder or granular raw material enters the weighing bin through the raw material line 1. 2. After weighing in weighing bin 2, the raw material is discharged through the discharge valve at the bottom of weighing bin 2 and enters the high-speed mixer 4 from the feeding line 3. During the weighing process, the air compressor 9 can pre-circulate and heat the gas inside the high-speed mixer 4 to preheat the internal temperature of the high-speed mixer 4 to a certain temperature to meet the temperature requirements during the mixing process. The gas inside the high-speed mixer 4 is heated by the air heater 8, and the air compressor 9 circulates the gas from the low-pressure pipeline 5 into the high-speed mixer 4. By replacing the gas inside the high-speed mixer 4, the room temperature gas is replaced with the gas at a suitable temperature. After weighing is completed in weighing bin 2, the raw material is sent into the high-speed mixer 4.

[0015] As a further embodiment of this utility model: the high-speed mixer 4 includes a housing 401, a bearing seat 402, an air pipe 406, a stirrer 407, a mounting base 408, and a nozzle 409. The bearing seat 402 is installed at the bottom of the housing 401. The bearing seat 402 is mounted on a rotatable drive shaft 410 via a bearing. The drive shaft 410 is equipped with a stirrer 407 located inside the housing 401. The mounting base 408 is installed inside the housing 401 below the stirrer 407. The mounting base 408 is equipped with a nozzle 409 that sprays air outward in the direction of airflow. The nozzle 409 is connected to a low-pressure pipeline 5 via an air pipe 406. During the process of feeding materials from the weighing bin 2 into the high-speed mixer 4, the stirrer 407 of the high-speed mixer 4 rotates and stirs, and the temperature inside the high-speed mixer 4 will rise relatively as it stirs.

[0016] In a preferred embodiment, the bottom of the agitator 407 is provided with an arc-shaped guide rib 411, which cuts the airflow and propels it outward for circulation. A valve 6 is installed on the low-pressure pipeline 5 to control the injection of gas into the high-speed mixer 4. The low-pressure pipeline 5 is connected to the air pipe 406, and a one-way valve is installed inside the air pipe 406. An air heater 8 is provided between the filter 7 and the air compressor 9. A drain valve 11 is installed at the bottom of the jacketed tank 10. The high-speed mixer 4 is existing technology and is equipped with a sensor to detect the internal temperature. The air heater 8 stops heating the air after preheating. The jacketed tank 10 is existing technology and has the advantage of temperature controllability. The air compressor... Air compressor 9 pre-compresses a portion of the gas into the jacketed tank 10 and raises or lowers the temperature to a suitable mixing temperature. During the stirring process, when the sensor detects that the internal temperature is too high, the air compressor 9 works to extract the gas inside the high-speed mixer 4. The gas inside the jacketed tank 10 is blown out through the air pipe 406 and nozzle 409 by opening valve 6. This method can replace the gas inside the high-speed mixer 4 to achieve the purpose of temperature control. When the gas is blown out from nozzle 409, it blows up the accumulated material around the dead corner at the bottom of the agitator 407 and adds it to the stirring. During the preheating and blowing process, valve 6 is in the open state, and in the closed state at other times.

[0017] In a preferred embodiment, the high-speed mixer 4 is further provided with a discharge end 403, a telescopic drive rod 404 and a discharge pipe 405. The discharge end 403 is installed on the bottom side of the housing 401, and the bottom of the discharge end 403 is connected to the discharge pipe 405. The telescopic drive rod 404 is installed at the end of the discharge end 403, and the telescopic end of the telescopic drive rod 404 is equipped with a blocking end head 412 that can slide inside the discharge end 403.
