Description

Technical Field

[0001] The invention relates to the technical field of talc production equipment, and in particular to a production process and production equipment of fine powder water-based talc. Background Art

[0002] As a plastic filling mineral, talc can effectively improve the elastic modulus of plastic parts. However, with the continuous improvement of plastic modification capacity, the gradual improvement of plastic performance requirements of downstream industries, and the improvement of environmental protection requirements of the whole society, the plastic modification industry has also put forward higher requirements for talc. On the one hand, the fineness of talc is required to be higher and higher to meet the requirements of plastic performance. On the other hand, the generation of dust and harmful gases should be reduced to ensure the health of the production environment. Finally, the unimpeded material discharge in the process should be ensured to meet the improvement of plastic modification capacity. However, the existing talc is not environmentally friendly during production. Talc is prone to generate dust during production, and talc is divided into multiple steps during production. The multiple steps require multiple processing to produce talc, which affects the production efficiency of talc.

The bearing 17 can provide guidance for the stirring shaft 15 when it rotates and ensure the stability of the stirring shaft 15 when it rotates.

[0055] As a technical optimization solution of the present invention, a second motor 22 is installed on the inner bottom wall of the shell 2, the output shaft of the second motor 22 passes through the unloading baffle 21 and is connected to the mounting block 24, a mounting rod 25 is installed on the side of the mounting block 24, and the end of the mounting rod 25 away from the mounting block 24 is rotatably connected to the rolling roller 26.

[0056] As a technical optimization scheme of the present invention, the second motor 22 is located below the unloading baffle 21, and the scraper 28 is fixedly sleeved on the output shaft of the second motor 22. The scraper 28 is located between the mold 20 and the unloading baffle 21. The scraper 28 is used to cut the paste talcum powder extruded into cylindrical strips during its rotation. The paste talcum powder can be cut into cylindrical paste talcum powder particles, which is convenient for the pelletizing process of the paste talcum powder extruded into cylindrical strips.

[0057] When the present invention is used, first, the talc raw material and water are introduced into the barrel 3 through the feed port 4, and the first motor 5 is started. The output shaft of the first motor 5 drives the driving gear 6 to rotate, and the driving gear 6 drives the gear ring 7 to rotate. The rotation of the gear ring 7 drives a plurality of driven gears to rotate, and then drives a plurality of stirring shafts 15 and stirring rods 16 to rotate. The stirring shaft 15 and the stirring rod 16 are used to stir and mix the talc raw material and water in the barrel 3, so that the talc raw material and the water can be fully and evenly mixed. While the talc raw material and the water are stirred by the stirring shaft 15 and the stirring rod 16, the bubbles generated when the talc raw material and the water are mixed can be punctured by the plurality of spikes on the outer wall of the stirring rod 16, so as to avoid the bubbles existing inside the talc raw material and the water when the talc raw material and the water are stirred and mixed, and the bubbles inside the talc raw material and the water can be punctured and removed by the spikes on the outer wall of the stirring rod 16, so as to ensure the uniformity and thoroughness of the stirring and mixing of the talc raw material and the water.

[0058] After the talc raw material and water are stirred and mixed evenly in the cylinder 3, a paste of talc powder is obtained. At this time, the electronic valve in the discharge hole 18 is started, and the paste of talc powder can drip onto the annular baffle 19 through the discharge hole 18. At this time, the second motor 22 is started, and the output shaft of the second motor 22 can drive the mounting block 24 to rotate. The rotation of the mounting block 24 can drive the mounting rod 25 to rotate. The rotation of the mounting rod 25 can make the rolling roller 26 rotatably connected to the mounting rod 25 roll on the annular baffle 19 to press the paste of talc powder. The stone powder can be crushed to crush the large particles of talc powder in the talc powder paste, and the threads on the outer wall of the crushing roller 26 can be used to disperse the weight of the crushing roller 26 on the one hand, and on the other hand, the talc powder paste can be dispersed through the threads, so that the extruded talc powder will not form overly compact particles. In addition, the inner wall and bottom surface of the annular baffle 19 are designed to be arc-shaped chamfers, which are convenient for the talc powder paste to gather to the crushing area of ​​the crushing roller 26, so that the crushing roller 26 can crush the talc powder paste.

[0059] The talc paste on the annular baffle 19 is squeezed when being rolled by the rolling roller 26, so that the talc paste enters the mold hole 23 provided on the mold 20 through the through hole on the annular baffle 19, and the talc paste is squeezed through the mold 20 and the mold hole 23, and the talc paste can be squeezed into a cylindrical strip of talc paste. At this time, the output shaft of the second motor 22 is rotated, and the rotation of the output shaft of the second motor 22 can drive the scraper 28 to rotate, and the talc paste squeezed into a cylindrical strip is cut during the rotation of the scraper 28, and the talc paste can be cut into cylindrical talc paste particles, which is convenient for the granulation process of the talc paste squeezed into a cylindrical strip.

[0060] The pelletized cylindrical talc paste particles fall on the unloading baffle 21. Because the unloading baffle 21 is tilted, the cylindrical talc paste particles falling on the unloading baffle 21 can roll downward along the tilted unloading baffle 21, and then fall on the conveyor belt 12. The conveyor belt 12 can be started to convey the cylindrical talc paste particles, and at the same time, the drying fan 27 is started to blow hot air to dry the cylindrical talc paste particles conveyed on the conveyor belt 12. The cylindrical talc paste particles can be dried to obtain cylindrical talc powder particles. When the cylindrical talc paste particles are dried, the temperature of the drying air blown by the drying fan 27 is controlled to be a hot air temperature of 170-190°C. This design can ensure that the cylindrical talc paste particles have suitable moisture content and maintain a good particle shape after drying.

[0061] The cylindrical talc powder particles after drying can be dropped into the collecting box 14 through the conveyor belt 12, and the dried cylindrical paste-like talc powder particles can be packaged.

[0062] In the process of talc production by using the device, talc powder and water are mixed in the cylinder 3, rolling and extrusion are completed in the shell 2, and granulation of the paste talc powder is completed in the shell 2. The talc processing process is completed in the cylinder 3 and the shell 2, and the talc is not in contact with the outside during the processing, so that the problem of generating a large amount of dust in the talc production process is avoided, the problem of easy generation of dust in the talc production process is eliminated, and the environmental protection of the talc production is improved. In addition, the device integrates the mixing, rolling, extrusion, granulation and drying of talc and water, and integrates multiple steps in the talc production into one step, thereby improving the efficiency of the talc production.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
