Description

Technical Field

[0001] This utility model relates to the field of electrode paste production technology, and more specifically, it relates to a feeding and metering device for electrode paste production. Background Technology

[0002] Electrode paste, also known as self-baking electrode, is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. It relies on the heat inside the submerged arc furnace to complete the baking process. Therefore, matching the consumption rate of the electrode with the baking rate is the key to the use of electrode paste. During the baking process, the electrode receives less conductive and radiant heat than in the past open furnace type, and only conductive heat is available. As a result, the heat obtained by the electrode from the furnace is greatly reduced. This requires improving the sintering performance of the electrode paste to compensate for this deficiency. During the feeding process, a metering device is needed to transport the raw materials to achieve the desired feeding effect.

[0003] However, the feeding structure of traditional feeding and metering devices is too simple. Most of them simply feed materials through pipes. This feeding method cannot adjust the feeding speed, which can easily lead to overflow during the subsequent introduction of materials into the metering device.

[0004] Furthermore, during the feeding process, prolonged use can cause electrode paste to clog the outlet of the pipe, affecting the normal operation of the feeding device. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a feeding and metering device for electrode paste production, which has the following advantages:

[0018] 1. By setting up a control box, tilting plate, connecting block and cylinder, the user can control the output end of the cylinder to drive the connecting block and tilting plate to move, so that the lower end is in the open state, which facilitates the subsequent feeding of material into the metering device. The user can also control the opening size of the tilting plate by controlling the cylinder to control the feeding speed of the electrode paste, which is convenient to use.

[0019] 2. By setting up a rotating shaft, motor and spiral conveyor blades, the user can add electrode paste into the feed cylinder through the feed pipe, and then control the motor to drive the rotating shaft and spiral conveyor blades to rotate, so as to guide the electrode paste into the guide cylinder and discharge it from the discharge pipe.

Inclined grooves 3 are provided on both sides of the inner wall of the control box 2. Inclined plates 4 are slidably provided inside the inclined grooves 3. One end of each inclined plate 4 extends into the interior of the control box 2 and is provided with an inclined surface. The two inclined surfaces can be connected to each other. The other end of each inclined plate 4 passes through the control box 2 and is fixedly provided with a connecting block 5. Inclined seats 6 are fixedly provided on both sides of the control box 2. A cylinder 7 is fixedly provided on the upper end of each inclined seat 6. The output end of each cylinder 7 is fixedly installed with the connecting block 5.

A conveying assembly is provided inside the feeding cylinder 1. An observation window 20 is provided on the outer wall of the feeding cylinder 1.

[0031] In this embodiment, the conveying assembly includes a rotating shaft 10, the upper end of which is rotatably mounted to the inner wall of the feeding cylinder 1. A motor 11 is fixedly mounted on the upper end face of the feeding cylinder 1, and the output end of the motor 11 is fixedly connected to the rotating shaft 10. A spiral conveying blade 12 is provided on the outer wall of the rotating shaft 10, and the spiral conveying blade 12 is located inside the feeding cylinder 1. A feeding pipe 13 is fixedly mounted on the outer wall of the feeding cylinder 1 at the upper end.

[0032] More specifically, the user can control the cylinder 7 to move the connecting block 5 and the inclined plate 4 at its output end, so that its lower end is in an open state, which facilitates the subsequent feeding into the metering device. The user can also control the cylinder 7 to adjust the opening size of the inclined plate 4 to control the feeding speed of the electrode paste, which is convenient to use. The user can also add the electrode paste into the feeding cylinder 1 through the feeding pipe 13, and then control the motor 11 to drive the rotating shaft 10 and the spiral conveying blade 12 to rotate, so as to guide the electrode paste into the guide cylinder 8 and discharge it from the discharge pipe 9, which is convenient for subsequent feeding. Moreover, when discharging, the spiral conveying blade 12 will give the electrode paste a certain pressure, which can reduce the blockage and facilitate the feeding process.

[0033] Please see Figure 1 , Figure 2 and Figure 4 As an implementation method for automatically feeding electrode paste: both sides of the control box 2 are provided with support legs 14, the lower end of the support legs 14 is fixedly provided with a conveyor belt 15, the outer wall of the conveyor belt 15 is provided with a support column 16, the upper end of the support column 16 is provided with a weighing platform 17, the upper end of the weighing platform 17 is provided with a holding trough 18, and the lower end of the conveyor belt 15 is fixedly provided with a support seat 19.

[0034] Specifically, the electrode paste leaking from the bottom of the discharge pipe 9 will enter the holding tank 18, which will facilitate subsequent metering operations via the weighing platform 17. Then, the conveyor belt 15 will be controlled to operate, thereby moving the weighing platform 17 and the holding tank 18. As a result, the electrode paste inside the holding tank 18 will fall and enter the equipment for easy use.

[0035] Please refer to Figure 2 As a further embodiment that allows the electrode paste to leak from the bottom of the device, the rotating shaft 10 and the spiral conveying blade 12 are both located at the upper end of the inclined plate 4.

[0036] Specifically, the spiral conveyor blades 12 can apply downward pressure to the electrode paste, causing it to leak out of the feeding device and reducing blockage.

[0037] In summary, when using the overall equipment: the user can add electrode paste into the feed cylinder 1 through the feed pipe 13, and then control the motor 11 to drive the rotating shaft 10 and the spiral conveyor blades 12 to rotate, so as to guide the electrode paste into the guide cylinder 8 and discharge it from the discharge pipe 9, which facilitates subsequent feeding into the holding tank 18. During discharge, the spiral conveyor blades 12 will apply a certain pressure to the electrode paste, thus reducing the blockage. After the electrode paste enters the holding tank 18, the user can perform a weighing operation through the weighing platform 17, and then control the conveyor belt 15 to operate, so as to drive the weighing platform 17 and the holding tank 18 to move, so that the electrode paste inside the holding tank 18 falls into the equipment, completing the feeding operation. The user can also control the cylinder 7 to drive the connecting block 5 and the inclined plate 4 to move, so as to adjust the size of the opening at the lower end of the two inclined plates 4, thereby controlling the feeding speed of the electrode paste, which increases the flexibility of the device during use.
