[0001] The present application relates to the field of energy-saving glazing devices, in particular to an energy-saving rotary automatic glazing device. BACKGROUND

[0002] The glazing device can be used for glazing porcelain insulators. The main functions of glazing porcelain insulators include protection, improvement of insulation performance and weather resistance. Specifically:

[0003] I. Protection: Glazing the surface of insulators can form a protective film to block the erosion of external air, water vapor and other chemical substances, reducing the possibility of external force affecting the insulators and prolonging their service life.

[0047] The present application provides an energy-saving rotary automatic glazing device as shown in Figures 1-9 The present application provides an energy-saving rotary automatic glazing device as shown in

[0048] The present application provides an energy-saving rotary automatic glazing device as shown in Figure 1 The energy-saving rotary automatic glazing device in the present application still includes a base component storage tank 2 and a rotating disc 6.

[0049] The storage tank 2 stores glaze, and a cover 10 is provided on the top of the storage tank 2 and can be opened to add glaze to the storage tank 2.

[0050] A motor 12 is provided below the rotating disc 6, and the motor 12 can drive the rotating disc 6 to rotate when started. The porcelain insulator 27 is installed on the rotating disc 6, and the porcelain insulator 27 can rotate synchronously with the rotating disc 6 when the rotating disc 6 rotates.

[0051] A first material pump 3 is provided on one side of the storage tank 2 and communicates with the inside of the storage tank 2. A hard discharge pipe 4 is provided on the upper end of the first material pump 3, and a soft discharge pipe 5 is provided on the upper end of the hard discharge pipe 4. When the first material pump 3 is started, the glaze stored in the storage tank 2 is discharged in sequence through the hard discharge pipe 4 and the soft discharge pipe 5 to the center or the center edge position of the upper surface of the porcelain insulator 27. With the rotation of the porcelain insulator 27, the glaze is uniformly dispersed on the surface of the porcelain insulator 27.

[0052] The porcelain insulator 27 has various types, which are generally classified into column type porcelain insulator, needle type porcelain insulator, disc type porcelain insulator, and cross arm insulator. In the glazing process, the glaze needs to be uniformly dispersed on the surface of the porcelain insulator 27.

[0053] If the glaze needs to be uniformly dispersed on the surface of the porcelain insulator 27, the glaze needs to flow to the center or the center edge position of the upper surface of the porcelain insulator 27, preferably the center position, so that the glaze can be uniformly dispersed on the surface of the porcelain insulator 27 with the rotation of the porcelain insulator 27.

[0054] However, in the prior art, the glaze flows downward in a parabolic trajectory during glazing. According to the height type of the porcelain insulator 27, the distance between the porcelain insulator 27 and the glaze spraying position needs to be adjusted in time, so that the glaze can flow to the center or the center edge position of the upper surface of the porcelain insulator 27. For example, in the patent with the title of “Rotary Ceramic Automatic Glazing Device” (Patent Application No. 201921603861.3), the height of the storage tank is usually adjusted to adjust the distance between the porcelain insulator 27 and the glaze spraying position.

[0055] In the prior art, the energy consumption during the lifting of the storage barrel is relatively large, and the energy saving performance still needs to be improved. Therefore, the present invention is developed for energy-saving glazing; specifically:

[0056] According to the parabola principle, by changing the initial launch angle of the ejecta (glaze slurry) in the parabola, the landing point of the glaze slurry can be changed without adjusting the distance between the porcelain insulator 27 and the glaze slurry ejection position.

[0057] The initial idea is to adjust the angle of the soft discharge pipe 5 by pneumatic means such as electric push rods, motors or electric cylinders, so as to change the angle at which the glaze slurry is sprayed from the soft discharge pipe 5. However, it has been verified in practice that the power consumption is still large and the energy saving performance still needs to be improved.

[0058] Therefore, the present invention adopts a method similar to inflating and deforming the airbag to drive the direction of the soft discharge tube 5 to change. Since the space inside the airbag is easy to adjust, the present invention adjusts the angle of the soft discharge tube 5 by inflation. Only a small amount of gas is needed to change the angle of the soft discharge tube 5, thereby achieving the purpose of not having to adjust the distance between the porcelain insulator 27 and the glaze slurry spraying position, thereby achieving further energy saving.

[0059] During specific implementation, a discharge channel 22 and an adjustment channel 23 are provided in the soft discharge pipe 5. The discharge channel 22 is connected to the interior of the hard discharge pipe 4 and is used to receive the glaze slurry discharged from the hard discharge pipe 4; the adjustment channel 23 is arranged in the sandwich structure of the soft discharge pipe 5, and a suction pump 7 is also provided on one side of the storage tank 2, and an air pipe 8 is provided on the suction pump 7. A connecting hole 24 is provided on one side of the adjustment channel 23, and the connecting hole 24 is connected to the air pipe 8; when the glaze slurry flows out through the soft discharge pipe 5, a glaze slurry column 28 is formed, and the glaze slurry column 28 flows to the center position of the upper surface of the porcelain insulator 27 or the edge near the center position.

[0060] During operation, if the height of the porcelain insulator 27 is small, the suction pump 7 can be started, and the suction pump 7 sequentially delivers the air source through the air pipe 8 and the connecting hole 24 into the regulating channel 23. The air source expands the regulating channel 23. Since the regulating channel 23 is arranged above the discharge channel 22, the cross-section of the regulating channel 23 is elliptical, and the thickness of the two side walls of the regulating channel 23 is greater than the thickness of the upper and lower walls of the regulating channel 23; therefore, when the regulating channel 23 expands and deforms, it tends to be as follows Figure 8 The upper and lower deformations shown in the figure increase the length of the wall above the soft discharge tube 5, so that the soft discharge tube 5 can bend downward. When the soft discharge tube 5 bends downward, the glaze slurry column 28 can smoothly contact the center position of the upper surface of the porcelain insulator 27 or the edge near the center position, so that the glaze slurry is evenly dispersed on the surface of the porcelain insulator 27.

[0061] Correspondingly, if the height of the porcelain insulator 27 is large, the air source in the adjustment channel 23 can be correspondingly extracted so that the bending angle of the soft discharge pipe 5 is smaller, so that the glaze slurry column 28 can smoothly contact the center position of the upper surface of the porcelain insulator 27 or the edge near the center position.

[0062] It should be noted that the soft discharge pipe 5 is made of elastic rubber material. Since the rubber material also has a certain hardness and the speed at which the glaze slurry is discharged from the soft discharge pipe 5 is limited, the glaze slurry can be stably discharged from the soft discharge pipe 5 at a suitable angle.

[0063] Furthermore, by controlling the amount of gas source entering the regulating channel 23, the expansion degree of the regulating channel 23 can be changed accordingly. When the regulating channel 23 expands too much, it can also squeeze the discharge channel 22 to become flat, thereby accelerating the discharge of the glaze slurry from the end of the soft discharge pipe 5, changing the injection force, and thus adjusting the landing point of the glaze slurry in a larger range.

[0064] Furthermore, by the reciprocating suction and exhaust of air into the regulating channel 23 by the suction pump 7, the glaze slurry in the discharge channel 22 can be squeezed reciprocatingly, thereby avoiding the situation where the glaze slurry blocks the discharge channel 22 and achieving a clearing effect.

[0065] It should be noted that when clearing the glaze slurry, the discharge of the glaze slurry should be controlled to fluctuate within a certain range and should not affect the glazing effect.

[0066] As an extension, when there is too much gas source in the regulating channel 23, the discharge channel 22 can be flattened and the glaze slurry can be cut off, so that the glaze slurry can be cut off from the end of the soft discharge pipe 5 in time, and there will be no problem of excess glaze slurry dripping onto the surface of the porcelain insulator 27 at the end of the soft discharge pipe 5 to form stains.

[0067] In another embodiment, reference Figures 3 to 5 As shown in the figure, an air outlet 25 is provided at one end of the soft discharge pipe 5 away from the hard discharge pipe 4. The air outlet 25 is connected between the outside of the soft discharge pipe 5 and the regulating channel 23. The cross-sectional area of ​​the air outlet 25 is smaller than the cross-sectional area of ​​the regulating channel 23. An electromagnetic valve 26 is provided in the air outlet 25. When the electromagnetic valve 26 is opened, the air source is continuously ejected from the air outlet 25, thereby cooling the glaze slurry just ejected from the end of the soft discharge pipe 5.

[0068] It should be noted that in the prior art, there is a glazing method in which an electric heating plate (not shown in the figure) is provided in the storage tank 2 to heat the glaze slurry, which can avoid the glaze slurry from agglomerating, allow the glaze slurry to be discharged and glazed smoothly, and increase the bonding force between the glaze slurry and the porcelain insulator 27.

[0069] It should be noted that if the gas source is continuously discharged from the air outlet hole 25, since the cross-sectional area of the air outlet hole 25 is smaller than the cross-sectional area of the adjusting channel 23, only a constant amount of gas source needs to be continuously supplied to the adjusting channel 23, which can ensure the expansion degree of the adjusting channel 23 while continuously discharging the gas source.

[0070] If the electromagnetic valve 26 is opened after the glazing is finished, the gas source sprayed from the air outlet hole 25 can be used to dry the surface of the porcelain insulator 27.
