Description

Technical Field

[0001] This application relates to the field of glass liquid stirring technology, and in particular to a stirring assembly and a glass liquid stirring device. Background Technology

[0002] Glass molten material stirring is a crucial step in the glass manufacturing process. During glass production, the batch materials are melted at high temperatures to form molten glass, but its composition and temperature are often uneven in the initial stages, which affects the quality and performance of the glass. Glass molten material stirring involves mechanically agitating the molten glass within the glass melting furnace using specific stirring equipment, such as stirring paddles and other stirring components.

[0003] However, in civilian glass kilns, the agitator is usually placed in a horizontal feed channel, with the flow direction of the molten glass parallel to the stirring direction of the agitator blades. This limits the force exerted by the agitator on the molten glass, resulting in poor stirring effect. Furthermore, when the molten glass stirring assembly is in operation, the molten glass at the edge of the assembly cannot be sufficiently stirred, leading to uneven mixing of the molten glass at the edge of the assembly. This results in localized uneven composition in the produced glass products, which in turn affects the quality of the glass products. Utility Model Content

[0004] The main purpose of this application is to provide a stirring assembly and a glass liquid stirring device, which aims to solve the problem of poor stirring effect of existing glass liquid stirrers in horizontal feeding channels.

[0005] To achieve the above objectives, this application provides a stirring assembly, which includes a stirring shaft and a stirring section; wherein the stirring section includes at least two stirring blades, the stirring blades are arranged parallel to the stirring shaft, and the stirring section is connected to the stirring shaft; wherein the cut of at least one stirring blade near the stirring shaft is oriented away from the stirring shaft, and the cut of at least one stirring blade away from the stirring shaft is oriented towards the stirring shaft.

[0006] Optionally, the stirring part further includes at least two connecting components, each including a first connecting rod and a second connecting rod; wherein the first connecting rod is disposed on the side wall of the stirring shaft; the second connecting rod is disposed on the side wall of the stirring shaft and spaced apart from the first connecting rod along the length direction of the stirring shaft; wherein the stirring blade is connected to the stirring shaft through the first connecting rod and the second connecting rod.

[0007] Optionally, the first connecting rod, the second connecting rod, and the stirring shaft are located on the same plane, and the included angles between two adjacent connecting components are equal.

[0008] Optionally, the cross-sectional shape of the stirring blade along the horizontal direction is a right trapezoid, and the hypotenuse of the right trapezoid is the cut of the stirring blade.

[0009] Optionally, the angle between the long side and the hypotenuse of the right trapezoid is α, where 30°≤α≤60°.

[0010] Optionally, the input end of the stirring shaft is connected to the output end of the motor, and the motor provides rotational driving force for the stirring shaft.

[0011] Secondly, in order to achieve the above objectives, this application also provides a glass liquid stirring device, the device including a horizontal feeding channel and two stirring components; wherein, the two stirring components are arranged side by side and spaced apart in the horizontal feeding channel along the length direction of the horizontal feeding channel, or arranged side by side and spaced apart in the horizontal feeding channel along the width direction of the horizontal feeding channel, and the rotation direction of the stirring components is horizontal.

[0012] The stirring assembly is any of the stirring assemblies described above.

[0013] Optionally, the two stirring components are equidistant from the bottom wall of the horizontal feed channel.

[0014] Optionally, the stirring assembly includes two connecting components, the included angle between the two connecting components is 180°, and the connecting components of the two stirring assemblies are perpendicular to each other.

[0015] Optionally, the horizontal feeding channel is provided with an observation port.

[0016] This application provides a stirring assembly and a glass molten agitator. By arranging at least two stirring blades parallel to the stirring shaft, the horizontally flowing glass molten material can cross the stirring blades, increasing the cutting and homogenizing force on the glass molten material and thus improving the stirring effect. By setting the cut of at least one stirring blade away from the stirring shaft towards the direction closer to the stirring shaft, the flow direction of the glass molten material can be changed, causing the glass molten material at the edge of the stirring assembly to flow towards the stirring shaft. Conversely, setting the cut of at least one stirring blade close to the stirring shaft towards the direction away from the stirring shaft can hinder the flow of glass molten material from the edge of the stirring assembly towards the stirring shaft, thereby ensuring that the glass molten material is fully stirred near the stirring shaft. Through the above arrangement, the stirring uniformity and stirring effect of the glass molten material are improved, thereby improving the quality of the glass product. Attached Figure Description

[0030] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

Figure 2 This is a top view of the stirring assembly in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of the stirring blade in an embodiment of this application.

[0032] Please combine Figure 1 and Figure 2 Referring to the present application, an embodiment of the present application provides a stirring assembly, which may include: a stirring shaft 1 and a stirring part 2; wherein, the input end of the stirring shaft 1 is connected to the output end of a motor, and the motor provides a rotational driving force for the stirring shaft 1, thereby driving the entire stirring assembly to rotate, so as to achieve stirring of the material to be stirred; wherein, the material to be stirred in the present application embodiment may be molten glass; the stirring part 2 may include at least two stirring blades 21, the stirring blades 21 are arranged parallel to the stirring shaft 1, and the stirring part 2 is connected to the stirring shaft 1; wherein, the cut of at least one stirring blade 21 near the stirring shaft 1 is arranged in a direction away from the stirring shaft 1, and the cut of at least one stirring blade 21 away from the stirring shaft 1 is arranged in a direction close to the stirring shaft 1.

[0033] The stirring assembly provided in this application embodiment, by arranging at least two stirring blades 21 parallel to the stirring shaft 1, enables the horizontally flowing molten glass to intersect with the stirring blades 21, increasing the cutting and homogenizing force on the molten glass and thus improving the stirring effect on the horizontally flowing molten glass. By setting the cut of at least one stirring blade 21 away from the stirring shaft 1 towards the direction close to the stirring shaft 1, the flow direction of the molten glass at the edge of the stirring assembly can be changed, causing the molten glass at the edge of the stirring assembly to flow towards the stirring shaft 1. Conversely, by setting the cut of at least one stirring blade 21 close to the stirring shaft 1 towards the direction away from the stirring shaft 1, the flow of molten glass from the edge of the stirring assembly to the stirring shaft 1 can be hindered, thereby ensuring that the molten glass is sufficiently stirred near the stirring shaft 1. Through the above arrangement, the stirring uniformity and stirring effect of the molten glass are improved, thereby improving the quality of the glass product.

[0034] like Figure 1 and Figure 2 As shown, in an exemplary embodiment, the stirring unit 2 may further include at least two connecting components 22, which may include: a first connecting rod 221 and a second connecting rod 222; wherein, the first connecting rod 221 is disposed on the side wall of the stirring shaft 1; the second connecting rod 222 is disposed on the side wall of the stirring shaft 1 and is spaced apart from the first connecting rod 221 along the length direction of the stirring shaft 1; wherein, the stirring blade 21 is connected to the stirring shaft 1 through the first connecting rod 221 and the second connecting rod 222.

[0035] In some embodiments, the first connecting rod 221, the second connecting rod 222 and the stirring shaft 1 are located on the same plane, and the included angle between two adjacent connecting components 22 is equal.

[0036] Specifically, the stirring assembly provided in this embodiment has two connecting components 22, and the included angle between the two connecting components 22 is 180°. It should be noted that this application does not impose a particular limitation on the number of connecting components 22. The number of connecting components 22 of the stirring assembly can be adaptively adjusted according to the actual stirring scenario. For example, the number of connecting components 22 can also be three, and the three stirring assemblies can be replaced by A, B, and C respectively, wherein the included angle between two adjacent connecting components 22 is equal; that is, the included angle between A and B is equal, the included angle between B and C is equal, and the included angle between C and A is equal (i.e., the included angle between A and B, B and C, and C and A are all equal to 120°). The equal included angle between two adjacent connecting components 22 can make the glass liquid contact the stirring blade evenly when stirring the glass liquid, and at the same time increase the stability of the entire stirring assembly.

[0037] More specifically, the stirring blade 21 can be connected to the stirring shaft 1 by means of the first connecting rod 221 and the second connecting rod 222. The spacing between the first connecting rod 221 and the second connecting rod 222 increases the stability of the stirring blade 21. When stirring the molten glass, the motor drives the stirring shaft 1 to rotate, and then the stirring shaft 1 drives the stirring blade 21 to rotate steadily through the connecting assembly 22 (the first connecting rod 221 and the second connecting rod 222), thereby completing the stirring of the molten glass.

[0038] Please see Figure 3 In an exemplary embodiment, the cross-sectional shape of the stirring blade 21 along the horizontal direction is a right trapezoid, and the hypotenuse of the right trapezoid is the cut of the stirring blade 21.

[0039] Optionally, the angle between the longer side and the hypotenuse of the right trapezoid is α, where 30°≤α≤60°.

[0040] This application adjusts the cutting angle of the stirring blade 21 (the angle α between the long side and the hypotenuse of the right trapezoid) according to the flow rate and viscosity of the molten glass. 30°≤α≤60° can increase the resistance effect of the stirring blade 21 of the stirring assembly on the molten glass, which is more conducive to the flow of the molten glass at the edge of the stirring assembly toward the stirring shaft 1. At the same time, it can prevent the flow of molten glass from the edge of the stirring assembly to the stirring shaft 1, so that the molten glass has enough time to be stirred near the stirring shaft 1.

[0041] Optionally, the input end of the stirring shaft 1 is connected to the output end of the motor, and the motor provides rotational driving force for the stirring shaft 1. It should be noted that the embodiments of this application do not specifically limit the specifications and model of the motor, and the motor can be selected according to the actual situation.

[0042] This application also provides a glass liquid stirring device, such as... Figures 4-7 As shown; the glass melt stirring device may include a horizontal feed channel 3 and two stirring components; wherein,

[0043] The horizontal feeding channel 3 is connected to the glass product forming equipment, and can horizontally transport molten glass to the glass product forming equipment; wherein, the horizontal feeding channel 3 is a channel arranged in a horizontal direction. Two stirring components are arranged side by side and spaced apart along the length direction of the horizontal feeding channel 3, or side by side and spaced apart along the width direction of the horizontal feeding channel 3, and the two stirring components rotate in opposite directions; wherein, the stirring components are the stirring components as described in any of the above embodiments.

[0044] Optionally, the two mixing components are aligned in a straight line, and the straight line is parallel to the length direction of the horizontal feeding channel 3, or the straight line is parallel to the width direction of the horizontal feeding channel 3.

[0045] Specifically, such as Figure 4 and Figure 5 As shown, molten glass enters the horizontal feeding channel 3 along the X direction (horizontal direction). Two stirring components, one rotating clockwise and the other counterclockwise, stir the molten glass flowing horizontally. Since the two stirring components are arranged side by side and spaced apart along the length of the horizontal feeding channel 3, the stirring component that first contacts the molten glass performs initial stirring, and the stirring component that contacts the molten glass later performs further stirring. By using two stirring components with opposite rotation directions to perform two-stage stirring of the molten glass, the uniformity of stirring of the molten glass is further improved.

[0046] More specifically, such as Figure 6 and Figure 7 As shown, molten glass enters the horizontal feeding channel 3 along the X direction (horizontal direction). Two stirring components rotate, one clockwise and the other counterclockwise, to stir the molten glass flowing horizontally. Since the two stirring components are arranged side by side and spaced apart along the width of the horizontal feeding channel 3, the molten glass flowing through the horizontal feeding channel 3 can be stirred in all directions. The molten glass is subjected to strong stirring force in different directions, making the stirring more uniform and the effect more significant.

[0047] In some embodiments, the stirring assembly may include two connecting components 22; the included angle between the two connecting components 22 is 180°, and the connecting components 22 of the two stirring assemblies are perpendicular to each other.

[0048] Optionally, the distance between the two mixing components and the bottom wall of the horizontal feed channel 3 is equal.

[0049] Specifically, the two mixing components are installed at the same height within the horizontal feeding channel 3, and the connecting components 22 are perpendicular to each other. In such a case... Figure 4 and Figure 5 In the described embodiment, since the connecting components 22 of the two stirring components are perpendicular to each other, the molten glass flows through the stirring component that first contacts the molten glass to perform initial stirring. When the stirring component rotates to the point where its connecting component 22 is parallel to the length direction of the horizontal feed channel 3, the molten glass flows through its two sides to the stirring component that contacts the molten glass later. The stirring component that contacts the molten glass later then just begins to obstruct the flow of the molten glass. Through the two stages of stirring devices arranged perpendicularly to each other, the uniformity of stirring is further improved.

[0050] Optionally, the horizontal feeding channel 3 is equipped with an observation port (not shown in the figure). During the stirring of the molten glass, the staff can observe the stirring components and stirring conditions inside the horizontal feeding channel 3 through the observation port. If the stirring components malfunction, they can be detected in time and quickly disassembled for repair, thus avoiding blockage of the horizontal feeding channel 3, reducing production interruption time, lowering maintenance costs, and greatly improving production efficiency.

[0051] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
