Description

Technical Field

[0001] This utility model belongs to the field of PA material mixing technology, specifically, it relates to a high-flowability PA material mixing equipment. Background Art

[0002] When mixing PA materials, different raw materials are typically poured in one bag at a time. The different particle sizes of these materials can easily cause similar materials to pile up, leading to uneven mixing and significant problems with product quality. Furthermore, larger particle sizes can also reduce reaction efficiency. Ordinary silos are merely for transferring materials, resulting in low mixing efficiency and a lack of mechanisms for rapid abrasive mixing. Therefore, there is currently a lack of equipment capable of simultaneously pouring in multiple raw materials, achieving uniform mixing, rapid abrasive mixing, and preventing excessively large particle sizes from negatively impacting reaction efficiency. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a high-flowability PA material mixing equipment, avoiding the troubles of lack of abrasive, weak flowability and low mixing efficiency in the past.

The inner rotating cylinder is driven to rotate by a motor, and the side wall of the inner rotating cylinder has multiple inner discharge holes. One end of the inner rotating cylinder is connected to the feeding hopper through an upper gate plate.

[0007] An upper support plate is installed on the lower side of the abrasive cylinder. A stirring shaft is installed in the center of the upper support plate through a bearing. A lower support plate is installed at the lower end of the stirring shaft. The discharge port is connected to both sides of the lower support plate through a lower gate plate.

[0008] According to one embodiment of the present invention, the abrasive cylinder contains a plurality of grinding balls, and the diameter of the grinding balls is larger than the inner discharge hole.

[0009] According to one embodiment of the present invention, the edge of the inner discharge hole is raised.

[0010] According to one embodiment of the present invention, the inner wall of the inner rotating cylinder has a liner plate, and the liner plate corresponds to the inner discharge hole.

[0011] According to one embodiment of the present invention, a screw conveyor is provided at the bottom of the above-mentioned feeding hopper to introduce materials.

[0012] According to one embodiment of the present invention, the stirring shaft is provided with multiple sets of stirring blades, and the stirring shaft is driven to rotate by a bottom motor.

[0013] Compared with the prior art, the present invention can achieve the following technical effects:

[0014] The material, such as PA, is received by the abrasive cylinder, ball-milled to a regular particle size, and then fed into the mixing zone. It is further mixed by the stirring shaft and finally discharged, avoiding the problems of uneven mixing and low efficiency in the past.

[0020] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0021] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a high-flowability PA material mixing device according to an embodiment of this utility model.

[0022] As shown in the figure, a high-flowability PA material mixing device includes: a machine body 10, with a feeding funnel 11 on one side of the upper end of the machine body 10 and discharge ports 12 on both sides of the lower end; an abrasive cylinder installed on the machine body 10 and located below the feeding funnel 11, the abrasive cylinder having an inner rotating cylinder 21 and an upper semi-circular cover 22, the inner rotating cylinder 21 being driven to rotate by a motor 30, and having multiple inner discharge holes on the side wall of the inner rotating cylinder 21, one end of the inner rotating cylinder 21 being connected to the feeding funnel 11 through an upper gate plate 41; an upper support plate 51 installed on the lower side of the abrasive cylinder, with a stirring shaft 60 mounted on the center of the upper support plate 51 via a bearing, a lower support plate 52 mounted on the lower end of the stirring shaft 60, and the discharge ports 12 being connected on both sides of the lower support plate 52 through the lower gate plate 42.

[0023] In one embodiment of this utility model, a feeding hopper 11 is installed on one side of the upper end of the machine body 10 for conveying raw materials to the abrasive cylinder. Preferably, a screw conveyor can be installed at the bottom of the feeding hopper 11 to introduce materials. A gate 41 can also be installed on the side of the feeding hopper 11 and the abrasive cylinder to open and close the material inlet.

[0024] The abrasive cylinder has an inner rotating cylinder section 21 and an upper semi-circular cover section 22. The inner rotating cylinder section 21 is stabilized by bearings at both ends and driven to rotate by a motor 30. Multiple grinding balls 70 are installed inside to ball mill the raw materials such as PA, thereby reducing the particle size, adapting to later high-efficiency reactions, and improving the flow mixing effect. Multiple sets of internal discharge holes are opened on the side wall of the inner rotating cylinder section 21 to discharge raw materials smaller than the particle size after continuous ball milling. The diameter of the grinding balls 70 is larger than the internal discharge holes. During rotation, the grinding balls continuously rub against each other, gradually grinding larger particles down to smaller sizes, which are eventually thrown out of the internal discharge holes. The spaced upper semi-circular cover section 22 provides obstruction, allowing the raw materials to fall into the mixing zone under their own gravity.

[0025] The mixing zone uses the upper support plate 51 and the lower support plate 52 to install the mixing shaft 60 with bearings to complete the mixing of raw materials in this zone, improve the uniformity of mixing, and finally open the lower gate 42 to complete the discharge.

[0026] Preferably, the stirring shaft 60 is provided with multiple sets of stirring blades 61, and the stirring shaft 60 is driven to rotate by a bottom motor, resulting in high stirring efficiency and uniform mixing.

[0027] The inner discharge hole of this invention has a raised edge, which prevents raw material particles from depositing and clogging, while increasing the friction between them, resulting in high ball milling efficiency.

[0028] In addition, the inner wall of the inner rotating cylinder 21 has a liner plate, which increases wear resistance and corresponds to the inner discharge hole.

[0029] In summary, this invention receives raw materials such as PA in an abrasive cylinder, ball-mills them to a regular particle size, and then discharges them into a mixing zone where they are further mixed by a stirring shaft before being discharged. This avoids the problems of uneven mixing and low efficiency that have been encountered in the past.

[0030] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
