Description

Technical Field

[0001] The invention belongs to the field of substrate glass kiln equipment, and in particular relates to a large-lead-out kiln electrode cooling device and an installation method thereof. Background Art

[0002] During the normal use of the substrate glass kiln, a water-cooling plate is provided at the rear end of the kiln electrode. The water-cooling plate is fixed to the rear end face of the electrode with bolts with holes, washers, nuts and pins. The water-cooling plate cools the electrode on the one hand, and provides heating current to the electrode through the terminal board behind the water-cooling plate on the other hand. In the existing technology, each group of kiln electrodes is composed of 18 identical electrode bricks, and the 18 electrode bricks are divided into 6 layers, with 3 bricks stacked as a whole in each layer. The rear end of each electrode brick is provided with bolt holes and pin holes for installing the water-cooling plate. The rear end of each group of electrodes is provided with two identical water-cooling plates, one above the other, and each water-cooling plate corresponds to 9 electrode bricks.

[0003] With the existing technology, on the one hand, due to the certain deviation in the processing of each electrode brick, the rear end faces of the electrode bricks are often not on the same plane after the installation of the 9 electrode bricks, and the rear end faces of some electrode bricks are not in contact with the water cooling plate or the contact area is small; on the other hand, since the water cooling plate is a stainless steel welded part, the deformation after welding is large and the surface flatness is poor, which will also lead to a reduction in the contact area between the rear end face of the electrode brick and the end face of the water cooling plate. If the rear end face of the kiln electrode brick is not in contact with the water cooling plate or the contact area is small, this will seriously affect the overall cooling effect of the kiln electrode and the uniformity of the distribution of the kiln electrode heating current, which will affect the service life of the kiln electrode on the one hand, and also affect the normal production process of the kiln on the other hand.

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] This embodiment provides a large-output kiln electrode cooling device such as Figure 2 and Figure 3 As shown, it includes: electrode brick 3, electrode silver plate 1, water cooling plate 2, pin 4 and fixing assembly; The electrode silver plate 1 is installed close to the end of the electrode brick 3, the water-cooling plate 2 is installed close to the electrode silver plate 1, the electrode silver plate 1 is installed between the electrode brick 3 and the water-cooling plate 2, the size of the water-cooling plate 2 is the same as that of the electrode silver plate 1, a first mounting hole is set on the side of the electrode brick 3, and a second mounting hole is set at the end of the electrode brick 3. The electrode silver plate 1 and the water-cooling plate 2 are installed at the end of the electrode brick 3 through a fixing component, and a pin 4 is set inside the electrode brick 3 through the first mounting hole and connected to the fixing component.

[0024] The electrode bricks 3 are provided with 18 pieces, and the structure of the electrode bricks 3 is as follows: Figure 4As shown, the pin 4 passes through the first mounting holes of the plurality of electrode bricks 3. Every three electrode bricks 3 are stacked into a group of electrode bricks 3, and each group of electrode bricks 3 is stacked to form 6 layers of electrode bricks 3. Every three groups of electrode bricks 3 are correspondingly installed with one electrode silver plate 1 and one water cooling plate 2.

[0025] like Figure 1 As shown, the material of the electrode silver plate 1 is pure silver, and the thickness of the electrode silver plate 1 is 1.0 mm to 5.0 mm.

[0026] The fixing assembly includes a bolt with a hole 5, a nut and a gasket. The bolt with a hole 5 is as follows. Figure 5 As shown; The pin 4 is installed in the through hole of the hole bolt 5, and the water cooling plate 2 and the electrode silver plate 1 are fixedly installed on the rear end of the electrode brick 3 through the hole bolt (5), nuts and gaskets.

[0027] Nine third mounting holes are arranged on the electrode silver plate 1, nine fourth mounting holes are arranged on the water cooling plate 2, the second mounting holes, the third mounting holes and the fourth mounting holes are arranged correspondingly, and the hole bolts 5 pass through the second mounting holes, the third mounting holes and the fourth mounting holes.

[0028] This embodiment also provides a method for installing a large-output kiln electrode cooling device, which specifically includes the following steps: The first step is to check and confirm that all 18 electrode bricks 3 of each set of kiln electrodes are installed in place; The second step is to place 18 bolts 5 with holes in the circular holes (i.e., the second mounting holes) at the rear end of each electrode brick 3; The third step is to install the six pins 4 in the circular holes (i.e., the first mounting holes) on the rear side of the electrode brick 3. Use one pin for each layer of three electrode bricks 3. Pay attention to check and confirm that the pins must pass through the holes of the bolts with holes that have been placed in the second mounting holes at the rear end of the electrode brick. Both ends of each pin must not be exposed on both sides of the electrode brick 3. Step 4: Place the electrode silver plate 1 on the installed bolts 5 with holes at the rear end of the electrode brick 3. Note that the round holes (i.e., the third installation holes) on the electrode silver plate 1 correspond to the bolts 5 with holes one by one, and the electrode silver plate 1 is close to the rear end surface of the electrode brick 3.

Then tighten all the nuts with a torque wrench, install the terminal board 6 on the water-cooling plate 2, and complete the installation.

[0029] The present embodiment provides a large-lead kiln electrode cooling device by arranging an electrode silver plate between the rear end of the kiln electrode and the water-cooling plate, and fixing the water-cooling plate and the electrode silver plate to the rear end of the electrode with bolts with holes, pins, nuts and washers, etc., and utilizing the good electrical conductivity and soft texture of silver to greatly increase the contact area between the rear end of the electrode and the water-cooling plate, thereby ensuring the overall cooling effect of the electrode, extending the service life of the electrode, and also ensuring that the kiln electrode heating current is more evenly distributed, thereby ensuring the normal production process.

[0030] In addition, since silver is relatively soft, an electrode silver plate is set between the rear end of the electrode and the water-cooling plate, and the electrode silver plate is installed between the electrode brick and the water-cooling plate using holed bolts, pins, nuts and gaskets. The extrusion deformation of the electrode silver plate effectively increases the contact area between the rear end faces of the 9 electrode bricks at the rear end of the electrode and the electrode silver plate on the one hand, and also effectively increases the contact area between the water-cooling plate and the electrode silver plate on the other hand, thereby effectively solving the problem of no contact or small contact area between the rear end faces of some electrode bricks and the end faces of the water-cooling plate, ensuring the overall cooling effect of the electrode, extending the service life of the electrode, and also ensuring a more uniform distribution of the heating current of the kiln electrode, ensuring the normal production process.

[0031] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects, not exclusive, and all changes within the scope of the present invention or equivalent to the scope of the present invention are included in the present invention.
