Description

Technical Field

[0001] This invention belongs to the field of household ceramics production technology, and in particular relates to a coaxial forward and reverse push clay refining machine. Background Technology

[0002] Clay is a crucial raw material for ceramic production, and its quality directly impacts the quality of the finished product. Numerous indicators measure clay quality, and the industry employs various processes to ensure these indicators meet standards. One particularly important indicator is porosity and density, typically achieved through clay refining. This process involves feeding clay into a clay refining machine for thorough mixing, sometimes accompanied by vacuuming to remove air bubbles. Existing clay refining machines, whether using augers or blades as agitators, mostly exhibit unidirectional clay flow. While this achieves the desired clay refining effect, its efficiency remains limited. Summary of the Invention

[0003] This invention provides a coaxial forward and reverse push clay refining machine to solve the problems mentioned in the background art.

[0004] The technical problem solved by this invention is achieved by the following technical solution:

[0005] A coaxial forward and reverse push clay refining machine includes a cylinder, a drive unit, a propulsion refining unit, an inner propulsion unit, a reverse push unit, and an extrusion unit.

[0006] The cylinder includes an outer cylinder, a discharge port, a feed port, and a through hole. The discharge port is located at the front end of the outer cylinder, through which the mud flows out of the plow mill. The feed port is located at the upper rear end of the outer cylinder, through which the mud flows into the outer cylinder for refining operations. The through hole is located at the rear end of the outer cylinder, and internal refining components are installed within the through hole. The drive unit is installed on the side at the rear of the cylinder and includes an outer ring gear, an inner ring gear, and a rotating shaft. The rotating shaft is connected to a power source externally and is also connected to both the outer ring gear and the inner ring gear. The front and rear sides of the outer ring gear mesh with the first and fourth follower gears, respectively, for transmission. The front and rear sides of the inner ring gear mesh with the second and third follower gears, respectively, for transmission.

[0007] The propulsion refining section includes a first shaft cylinder, a first turntable, joints, a first follower gear, and propulsion blades. The first shaft cylinder is hinged and installed in the through hole of the cylinder body. The first turntable is installed at the front end of the first shaft cylinder, and three joints are evenly distributed on the first turntable. Propulsion blades are installed on the joints. The first follower gear is installed at the rear end of the first shaft cylinder and is driven by the outer ring gear. The inner propulsion section includes an inner shaft cylinder, a connecting disc, small blades, and a second follower gear. The inner shaft cylinder is fitted inside the first shaft cylinder. The front end of the inner shaft cylinder has a connecting disc, and small blades are installed on the connecting disc. The rotation of the small blades pushes the mud forward. The rear end of the inner shaft cylinder has a second follower gear, which meshes with the inner ring gear for transmission. The reverse thrust section includes a reverse thrust cylinder, a reverse thrust disc, reverse thrust blades, and a third follower gear. The reverse thrust cylinder is fitted inside the inner cylinder. The front end of the reverse thrust cylinder has a reverse thrust disc, on which reverse thrust blades are mounted. The reverse thrust blades push the slurry backward. The rear end of the reverse thrust cylinder has a third follower gear, which meshes with the inner ring gear for transmission. The extrusion section includes a mandrel, a fourth turntable, extrusion blades, a fourth follower gear, and a front end support. The mandrel is fitted inside the reverse thrust cylinder. The front end of the mandrel has a fourth turntable, on which extrusion blades are mounted. The rear end of the mandrel has a fourth follower gear, which meshes with the outer ring gear for transmission.

[0008] Furthermore, the front end of the outer cylinder has a constriction zone. When the mud flows from the outer cylinder to the constriction zone, the mud undergoes a final compression as the diameter decreases.

[0009] Furthermore, the first turntable at the front end of the first shaft cylinder has two sets, each of which is equipped with a set of propulsion blades. The two sets of propulsion blades are distributed alternately on the turntables, forming a complementary propulsion effect in the entire internal cross section of the outer cylinder.

[0010] Furthermore, the inner shaft has a first retaining ring groove, on which a retaining ring is installed to limit the relative position between the inner propulsion section and the propulsion refining section.

[0011] Furthermore, the envelope diameter of the thrust blades is between that of the propulsion blades and the bladelets.

[0012] Furthermore, the thrust shaft has a second snap ring groove, on which a snap ring is installed to serve as a limit.

[0013] Furthermore, the number of extrusion blades is twice that of the propulsion blades, improving the efficiency of mud extrusion.

[0014] Furthermore, the front end of the core rod is hinged to the front end bracket, which is fitted onto the inner wall of the outer cylinder to provide mounting support for the front end of the core rod. The end of the core rod extends beyond the rear end face of the fourth follower gear and is used for hinged support at the end.

[0015] The beneficial effects of this invention are:

[0016] This invention is used in the clay refining process of ceramic production. It has four sets of stirring blades, which are driven by the same drive device. Each of the four sets of stirring blades performs its own function, forming a multi-layer circulation of clay inside the cylinder, which fully stirs and refines the clay, thereby improving the refining efficiency.

[0021] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0022] See Figures 1-3 The coaxial forward and reverse push clay refining machine shown includes a cylinder 10, a drive unit 20, a propulsion refining unit 30, an inner propulsion unit 40, a reverse push unit 50, and an extrusion unit 60.

[0023] The cylinder 10 includes an outer cylinder 11, a constriction zone 12, a discharge port 13, a feed port 14, and a through hole 15. The front end of the outer cylinder 11 has a constriction zone 12. When the mud flows from the outer cylinder 11 to the constriction zone 12, the mud undergoes a final compression as the diameter decreases. The front end of the outer cylinder 11 has a discharge port 13, from which the mud flows out of the plow mill. The upper rear end of the outer cylinder 11 has a feed port 14, from which the mud flows into the outer cylinder 11 for refining operations. The rear end of the outer cylinder 11 has a through hole 15, in which internal refining components are installed.

[0024] The drive unit 20 is installed on the side behind the cylinder 10. The drive unit 20 includes an outer ring gear 21, an inner ring gear 22 and a rotating shaft 23. The rotating shaft 23 is connected to a power source. The power source drives the various components inside the entire device to rotate, realizing the refining operation. The rotating shaft 23 is connected to both the outer ring gear 21 and the inner ring gear 22. The front and rear sides of the outer ring gear 21 are respectively engaged with the first follower gear 34 and the fourth follower gear 64 for transmission. The front and rear sides of the inner ring gear 22 are respectively engaged with the second follower gear 44 and the third follower gear 54 for transmission.

[0025] The refining section 30 includes a first shaft cylinder 31, a first turntable 32, joints 33, a first follower gear 34, and propulsion blades 35. The first shaft cylinder 31 is hinged and installed in the through hole 15 of the cylinder body 10. The first turntable 32 is installed at the front end of the first shaft cylinder 31. Three joints 33 are evenly distributed on the first turntable 32, and propulsion blades 35 are installed on the joints 33. The first follower gear 34 is installed at the rear end of the first shaft cylinder 31 and is driven by the outer ring gear 21. There are two first turntables 32 at the front end of the first shaft cylinder 31. Each of the two turntables 32 is equipped with a set of propulsion blades 35. The two sets of propulsion blades 35 are staggered on the turntables, forming a complementary propulsion effect in the internal cross section of the entire outer cylinder 11.

[0026] The inner propulsion section 40 includes an inner shaft cylinder 41, a connecting disc 42, small blades 43, and a second follower gear 44. The inner shaft cylinder 41 is fitted inside the first shaft cylinder 31. The front end of the inner shaft cylinder 41 has a connecting disc 42, on which small blades 43 are mounted. The rotation of the small blades 43 pushes the mud forward, primarily to push the mud near the axis of the cylinder 10 forward. The rear end of the inner shaft cylinder 41 has a second follower gear 44, which meshes with the inner ring gear 22 for transmission. The inner shaft cylinder 41 has a first snap ring groove 411, on which a snap ring is mounted to limit the relative position between the inner propulsion section 40 and the propulsion refining section 30. It should be noted that in this embodiment, multiple components should be provided with a combination of snap ring grooves and snap rings for limiting the position. This embodiment only shows a small part of this. Those skilled in the art can easily implement the combination of snap ring grooves and snap rings at necessary locations based on the description in the specification and the requirements of the technical solution. Further details are omitted here.

[0027] The reverse thrust unit 50 includes a reverse thrust cylinder 51, a reverse thrust disk 52, reverse thrust blades 53, and a third follower gear 54. The reverse thrust cylinder 51 is fitted inside the inner cylinder 41. The front end of the reverse thrust cylinder 51 has a reverse thrust disk 52, on which the reverse thrust blades 53 are mounted. The reverse thrust blades 53 push the mud backward. The envelope diameter of the reverse thrust blades 53 is between that of the propulsion blades 35 and the small blades 43. The third follower gear 54 is mounted at the end of the reverse thrust cylinder 51 and meshes with the inner ring gear 22 for transmission. The reverse thrust cylinder 51 has a second snap ring groove 511, on which a snap ring is mounted for limiting the movement.

[0028] The extrusion section 60 includes a core rod 61, a fourth turntable 62, extrusion blades 63, a fourth follower gear 64, and a front end support 65. The core rod 61 is fitted inside the thrust cylinder 51. The front end of the core rod 61 has a fourth turntable 62, on which extrusion blades 63 are installed. The number of extrusion blades 63 is twice that of the propulsion blades 35, thereby improving the efficiency of slurry extrusion. The end of the core rod 61 has a fourth follower gear 64, which meshes with the outer ring gear 21 for transmission. The front end of the core rod 61 is hinged to the front end support 65, which is fitted inside the inner wall of the outer cylinder 11 to provide mounting support for the front end of the core rod 61. The end of the core rod 61 extends beyond the rear end face of the fourth follower gear 64 and is used for hinged support at the end.

[0029] Finally, the installation tilt direction of each stage of the blades should be designed in conjunction with the rotation direction of the shaft and the direction of the mud push. For example, if the first shaft cylinder 31 and the inner shaft cylinder 41 rotate in the same direction, and the propulsion blade 35 and the small blade 43 push the mud in the same direction, then the installation tilt direction of the propulsion blade 35 and the small blade 43 should be the same. Similarly, the installation tilt direction of the reverse thrust blade 53 and the extrusion blade 63 should be the same, while the installation tilt direction of the extrusion blade 63 should be opposite to that of the propulsion blade 35. Furthermore, to further optimize the working efficiency of the blades, the installation tilt angle of each group of blades can also be further optimized.

[0030] Finally, it should be noted that, for ease of demonstration and explanation of the main components of this embodiment, some supporting components have been omitted from this embodiment and the accompanying drawings. These supporting components are easily implemented by those skilled in the art. Furthermore, to enable the implementation of this embodiment, the components described herein typically need to be disassembled into multiple parts, manufactured separately, and then assembled, which is readily understood by those skilled in the art.

[0031] The working principle of this invention is as follows: Slurry is fed into the cylinder 10 through the inlet 14. The drive unit 20 drives the entire device to rotate. The outer ring gear 21 drives the first follower gear 34 and the fourth follower gear 64. According to the basic principle of gear meshing transmission, the first follower gear 34 and the fourth follower gear 64 rotate in opposite directions. The inner ring gear 22 drives the second follower gear 44 and the third follower gear 54 to rotate. The second follower gear 44 and the third follower gear 54 rotate in opposite directions. Therefore, it is easy to see that the first follower gear 34 and the second follower gear 44 rotate in the same direction. Similarly, the rotation directions of all gears in this embodiment and their respective relationships can be understood. Each follower gear drives the blades it is connected to to rotate. Technically, the propulsion blade 35 pushes the slurry forward, the small blade 43 also pushes the slurry forward, the reverse thrust blade 53 pushes the slurry backward (i.e., reverse thrust), and the extrusion blade 63 pushes the slurry forward. Thus, the slurry forms a multi-layered circulating flow within the outer cylinder 11. To achieve the aforementioned direction of clay propulsion, the installation tilt direction of each blade should be matched with the rotation direction of each gear. Based on the above analysis, this is not particularly difficult. After being propelled and refined by each set of blades, the clay flows through the closing area 12 and then exits from the discharge port 13, completing the clay refining operation.

[0032] The above embodiments primarily illustrate the coaxial forward and reverse pushing clay refining machine of the present invention. Although only a limited number of embodiments and technical features have been described, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are considered illustrative rather than limiting, and the present invention may cover various modifications and substitutions without departing from the spirit and scope of the invention as defined by the appended claims.
