Description

Technical Field

[0001] This application relates to the technical field of glass production equipment, and more specifically, to a sealing structure and a mixer having therein. Background Technology

[0002] In the batching production line of display glass, a mixer is required to mix the batch materials. The uniformity of the mixture directly affects the quality and performance of the glass during subsequent melting and forming processes. All component batch materials are dry powders, placed inside the mixing drum of the mixer. The mixing drum is equipped with stirring blades, which rotate to achieve uniform mixing of the batch materials.

[0003] Some existing devices (e.g., authorized publication number CN204841843U, titled "A Dry Ultrafine Grinding Device") use a hopper connected to the top of the grinding chamber to feed the batch material. An adjustable speed motor is installed below the grinding chamber and is connected to a central shaft. The bottom of the grinding chamber has a through-hole through which the central shaft extends into the chamber. Blades are attached to the central shaft, and as the central shaft rotates, it drives the blades to grind and mix the batch material inside the grinding chamber. While this device can achieve uniform mixing, the powdered state of the powdered material makes it prone to overflowing from the through-hole, leading to material waste and potentially affecting the connection between the adjustable motor and the central shaft. Utility Model Content

[0004] This application provides a sealing structure and a mixer having the same, to solve the problem in the prior art where the batch material easily overflows from the mixing drum during mixing.

[0005] According to the sealing structure provided in this application, the sealing structure is located inside the mixing drum of a mixer, and there is a gap between the rotating housing and the inner wall of the mixing drum. The sealing structure includes an annular sealing block and an annular sealing baffle. The annular sealing block is installed on the inner wall of the mixing drum. The annular sealing baffle is located above the annular sealing block, and the annular sealing baffle is disposed close to the inner wall of the mixing drum, with a gap between the annular sealing baffle and the inner wall of the mixing drum. The first end of the annular sealing baffle is connected to the rotating housing, and the second end of the annular sealing baffle is bent towards the inner wall of the mixing drum, with the surface of the bent portion fitting against the annular sealing block. The annular sealing baffle and the gap are correspondingly arranged.

[0006] In some embodiments, the projection of the annular sealing block in the vertical direction has a first plane, a second plane, a third plane, and a fourth plane. The first plane and the second plane are arranged opposite to each other, and the third plane and the fourth plane are arranged opposite to each other and parallel to each other. The two ends of the first plane are connected to the third plane and the fourth plane respectively, and the two ends of the second plane are connected to the third plane and the fourth plane respectively. The first plane is in contact with the curved portion of the annular sealing baffle.

[0007] In some embodiments, the fourth plane is in contact with the inner wall of the mixing cylinder, the second plane and the third plane are perpendicularly arranged, and the first plane is an inclined plane or a plane. When the first plane is an inclined plane, it gradually tilts towards the second plane from the direction away from the inner wall of the mixing cylinder.

[0008] In some embodiments, a pad is bolted to the second plane, and the pad abuts against the inner wall of the mixing cylinder.

[0009] This application also provides a mixer, which includes a sealing structure.

[0010] In some embodiments, the mixer further includes a mixing cylinder with an indentation at the bottom center to form an installation groove, such that the mixing cylinder has a first annular inner wall and a second annular inner wall. An annular sealing block and an annular sealing baffle are both disposed on the circumferential outer side of the first annular inner wall. The annular sealing block is connected to the first annular inner wall by a fixing screw, and the annular sealing baffle is disposed close to the first annular inner wall and has a spaced distance from the first annular inner wall.

[0011] In some embodiments, the mixer further includes a rotating housing, which is partially located in a mounting groove. An opening is provided circumferentially on the first annular inner wall. Both ends of the rotating housing extend into the mixing cylinder through the opening. There is a gap between the rotating housing and the first annular inner wall.

[0012] In some embodiments, the mixer further includes a geared motor and a drive shaft. The geared motor is disposed in a mounting slot, a first end of the drive shaft is connected to the geared motor, and a second end of the drive shaft is connected to the rotating housing.

[0013] In some embodiments, the mixer further includes mixing blades, with at least two sets of mixing blades provided. The two sets of mixing blades are rotatably and symmetrically mounted at both ends of the rotating housing, and both sets of mixing blades are located between the first annular inner wall and the second annular inner wall.

[0014] In some embodiments, the mixer further includes an annular support plate, the annular support frame being sleeved on the circumferential outer side of the drive shaft, the annular support plate being located in the mounting groove and connected to the inner wall of the mounting groove.

[0015] The technical solution of this application involves a sealing structure located inside the mixing drum of a mixer. A gap exists between the rotating housing and the inner wall of the mixing drum to ensure that the rotating housing does not interfere with the inner wall of the mixing drum during rotation. The sealing structure includes an annular sealing block and an annular sealing baffle. The annular sealing block is installed and fixed on the inner wall of the mixing drum. The annular sealing baffle is located above the annular sealing block, close to the inner wall of the mixing drum, and spaced apart from it. This arrangement ensures that the annular sealing baffle is not interfered with by the inner wall of the mixing drum during rotation. The first end of the annular sealing baffle is connected to the rotating housing, and rotates synchronously under the drive of the rotating housing. The second end of the annular sealing baffle bends towards the inner wall of the mixing drum, and the surface of the bent portion fits against the annular sealing block. The annular sealing baffle and the gap are correspondingly arranged, allowing the annular sealing baffle to form a seal with the annular sealing block, effectively preventing material from overflowing from the gap in the mixing drum. The technical solution of this application effectively solves the problem in the prior art where batch materials easily overflow from the mixing drum during mixing. Attached Figure Description

[0023] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] like Figure 1 and Figure 2 As shown, the embodiment relates to a sealing structure 10, which is located inside the mixing cylinder 20 of a mixer. A gap 80 exists between the rotating housing 30 and the inner wall of the mixing cylinder 20. The sealing structure 10 includes an annular sealing block 11 and an annular sealing baffle 12. The annular sealing block 11 is installed on the inner wall of the mixing cylinder 20. The annular sealing baffle 12 is located above the annular sealing block 11, close to the inner wall of the mixing cylinder 20, and has a gap between it and the inner wall. The first end of the annular sealing baffle 12 is connected to the rotating housing 30, and the second end of the annular sealing baffle 12 bends towards the inner wall of the mixing cylinder 20. The surface of the bent portion fits against the annular sealing block 11. The annular sealing baffle 12 and the gap 80 are correspondingly arranged.

[0026] Applying the technical solution of this embodiment, the sealing structure 10 is located inside the mixing cylinder 20 of the mixer, and the rotating housing 30 and the inner wall of the mixing cylinder 20 have a gap 80 to ensure that the rotating housing 30 does not interfere with the inner wall of the mixing cylinder 20 when rotating. The sealing structure 10 includes: an annular sealing block 11 and an annular sealing baffle 12. The annular sealing block 11 is installed on the inner wall of the mixing cylinder 20 for fixation. The annular sealing baffle 12 is located above the annular sealing block 11, and the annular sealing baffle 12 is arranged close to the inner wall of the mixing cylinder 20, and the annular sealing baffle 12 has a gap distance from the inner wall of the mixing cylinder 20. The purpose of this arrangement is to ensure that the annular sealing baffle 12 is not interfered with by the inner wall of the mixing cylinder 20 during rotation. The first end of the annular sealing baffle 12 is connected to the rotating housing 30. The annular sealing baffle 12 rotates synchronously under the drive of the rotating housing 30. The second end of the annular sealing baffle 12 bends towards the inner wall of the mixing cylinder 20, and the surface of the bent portion fits against the annular sealing block 11. The annular sealing baffle 12 and the gap 80 are correspondingly arranged. This arrangement allows the annular sealing baffle 12 to form a seal with the annular sealing block 11, effectively preventing material in the mixing cylinder 20 from overflowing from the gap 80. The technical solution of this embodiment effectively solves the problem in the prior art where the batch material 100 easily overflows from the mixing cylinder 20 during mixing.

[0027] It should be noted that the first end of the annular sealing baffle 12 is welded to the rotating housing 30. Both the annular sealing block 11 and the annular sealing baffle 12 are located within the accommodating space 24. The space between the annular sealing baffle 12 and the annular sealing block 11 will gradually be filled with the powder of the compound material 100, forming a better sealing effect. Even if some of the powder of the compound material 100 overflows from between the annular sealing baffle 12 and the annular sealing block 11 and enters between the annular sealing baffle 12 and the inner wall of the mixing cylinder 20, the compound material 100 is no longer subjected to the force of the mixing blade 60 rotating. The compound material 100 falls into the curved part of the annular sealing baffle 12 and is not easy to overflow from the gap 80. Furthermore, since the annular sealing block 11 and the annular sealing baffle 12 are fitted together and do not exert any force, the rotation of the annular sealing baffle 12 will not be affected.

[0028] like Figure 2As shown, in some embodiments, the projection of the annular sealing block 11 in the vertical direction has a first plane 111, a second plane 112, a third plane 113, and a fourth plane 114. The first plane 111 and the second plane 112 are arranged opposite to each other, and the third plane 113 and the fourth plane 114 are arranged opposite to each other and parallel to each other. The two ends of the first plane 111 are connected to the third plane 113 and the fourth plane 114 respectively, and the two ends of the second plane 112 are connected to the third plane 113 and the fourth plane 114 respectively. The first plane 111 fits into the curved portion of the annular sealing baffle 12, which can effectively prevent the material 100 from overflowing from the gap 80. At the same time, this arrangement also ensures that the rotation of the annular sealing baffle 12 is not affected. The projection of the annular sealing block 11 in the horizontal direction is a circle, and the annular sealing block 11 is sleeved on the circumferential outer side of the first annular inner wall 22.

[0029] like Figure 2 As shown, in some embodiments, the fourth plane 114 is in contact with the inner wall of the mixing cylinder 20, the second plane 112 and the third plane 113 are perpendicularly arranged, and the first plane 111 is either an inclined plane or a flat plane. When the first plane 111 is an inclined plane, it gradually slopes towards the second plane 112 from the direction away from the inner wall of the mixing cylinder 20. The inclined plane makes it less likely for the batch material 100 to remain on the first plane 111, and therefore less likely to overflow from the point where the annular sealing baffle 12 is in contact with the first plane 111.

[0030] like Figure 2 As shown, in some embodiments, a soft pad 13 is bolted onto the second plane 112, and the soft pad 13 abuts against the inner wall of the mixing cylinder 20. The soft pad is made of rubber or plastic, and the annular sealing block 11 is connected to the inner wall of the mixing cylinder 20 by a fixing screw. At this time, the soft pad elastically deforms, thereby abutting against the inner wall of the mixing cylinder 20, and the batch material 100 is not easy to overflow from the gap between the annular sealing block and the inner wall of the mixing cylinder 20.

[0031] like Figure 1 and Figure 2As shown, this embodiment also provides a mixer, which includes a sealing structure 10. The mixer also includes a mixing cylinder 20, with a recessed mounting groove 21 formed at the bottom center of the mixing cylinder 20. The vertical projection of the mounting groove 21 is circular. The mounting groove 21 gives the mixing cylinder 20 a first annular inner wall 22 and a second annular inner wall 23. An annular sealing block 11 and an annular sealing baffle 12 are both disposed on the circumferential outer side of the first annular inner wall 22. The annular sealing block 11 is connected to the first annular inner wall 22 by a fixing screw. The mounting height of the annular sealing block 11 on the first annular inner wall 22 can be adjusted by the fixing screw. The annular sealing baffle 12 is disposed close to the first annular inner wall 22 and has a gap distance from the first annular inner wall 22. This arrangement is so that the annular sealing baffle 12 can both seal the gap 80 and rotate with the rotating housing 30.

[0032] like Figure 1 As shown, in some embodiments, the mixer further includes a rotating housing 30, which is partially located within the mounting groove 21. A first annular inner wall 22 has circumferential openings. Both ends of the rotating housing 30 extend through these openings into the mixing cylinder 20. The rotating housing 30 rotates along these openings. A gap 80 exists between the rotating housing 30 and the first annular inner wall 22, ensuring that the rotation of the rotating housing 30 is unaffected by the first annular inner wall 22. It should be noted that the bottom 211 of the mounting groove is connected to the interior of the mixing cylinder 20 via a connecting rod. In this case, the bottom 211 of the mounting groove is located above the rotating housing 30. The bottom 211 of the mounting groove has an inclined surface sloping towards the rotating housing 30. This design prevents some of the airborne batching material 100 from overflowing from the openings and instead allows it to fall back down from the bottom 211 of the mounting groove.

[0033] like Figure 1 As shown, in some embodiments, the mixer further includes a geared motor 40 and a drive shaft 50. The geared motor 40 is disposed in the mounting groove 21, and the first end of the drive shaft 50 is connected to the geared motor 40 for transmission. The geared motor 40 provides driving force to the drive shaft 50, and the second end of the drive shaft 50 is connected to the rotating housing 30, driving the rotating housing 30 to rotate synchronously.

[0034] like Figure 1As shown, in some embodiments, the mixer further includes mixing blades 60. At least two sets of mixing blades 60 are provided, and the two sets of mixing blades 60 are rotatably and symmetrically mounted at both ends of the rotating housing 30. Both sets of mixing blades 60 and both ends of the rotating housing 30 are connected by bearings. Both sets of mixing blades 60 are located between the first annular inner wall 22 and the second annular inner wall 23. As the rotating housing 30 rotates, the two sets of mixing blades 60 rotate synchronously around the drive shaft 50. During rotation, the mixing blades 60 are subjected to the force of the batch material 100. Since the mixing blades 60 and the rotating housing 30 are rotatably connected, the mixing blades 60 also rotate around the rotating housing 30 as a pivot, crushing and mixing the batch material 100 between the first annular inner wall 22 and the second annular inner wall 23.

[0035] like Figure 1 As shown, in some embodiments, the mixer further includes an annular support plate 70, which is sleeved on the circumferential outer side of the drive shaft 50. The annular support plate 70 is located within the mounting groove 21 and connected to the inner wall of the mounting groove 21. The geared motor 40 is connected to the annular support plate 70 to achieve a stable installation.
