Description

Technical Field

[0001] This utility model relates to the field of graphite motor impregnation technology, and in particular to an impregnation device for graphite electrode production. Background Technology

[0002] Graphite electrode impregnation solution is a liquid material used to impregnate graphite electrodes, and its main component is bitumen. The function of the impregnation solution is to penetrate the impregnating agent into the pores of the graphite electrode through physical or chemical means, thereby enhancing the mechanical strength, corrosion resistance, and thermal conductivity of the graphite electrode.

[0003] When graphite electrodes are impregnated in an impregnation device, the electrodes are submerged inside the device and the bottom of the electrodes is attached to the bottom of the device. This prevents the asphalt from penetrating the bottom of the graphite electrodes well, resulting in uneven impregnation and thus reducing the mechanical strength, corrosion resistance, and thermal conductivity of the graphite electrodes.

[0008] An impregnation apparatus for producing graphite electrodes includes a heating tank and a support point switching mechanism, wherein the support point switching mechanism is provided at the bottom of the heating tank.

Several first cams are arranged from left to right on the rotating shaft, and a second cam is provided between each of the first cams. The second cams are all located outside the rotating shaft. One rotating shaft is connected to another rotating shaft via a transmission belt. The rotation drive is connected to one of the rotating shafts.

[0011] Furthermore, the first cam is provided with a first support portion, and the second cam is provided with a second support portion, with the first support portion on the first cam and the second support portion on the second cam being alternately arranged on the rotating shaft.

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this invention are as follows: In actual production and use, when it is necessary to impregnate the graphite electrode, the cylindrical graphite electrode can be placed inside the heating tank, allowing the graphite electrode to be submerged in the impregnation liquid within the heating tank. Several first cams are placed to support the bottom of the graphite electrode, enabling the impregnation liquid to better penetrate the bottom of the graphite electrode. During impregnation, the heating tank can be operated to heat the impregnation liquid, thereby increasing its fluidity. When better impregnation is needed at the position supported by the first cam, a rotating drive can be operated to drive a rotating shaft to rotate. This rotating shaft, through a transmission belt, drives another rotating shaft to rotate synchronously. Subsequently, the rotating shaft drives the first and second cams to rotate, allowing the second cam to support the remaining positions at the bottom of the graphite electrode and releasing the original support of the first cam at the bottom of the graphite electrode. This allows the impregnation liquid to better penetrate the original support positions of the first cam, thereby reducing impregnation dead zones and achieving better overall impregnation of the graphite electrode. This results in more uniform impregnation of the graphite electrode, thereby improving its mechanical strength, corrosion resistance, and thermal conductivity. Attached Figure Description

Detailed Implementation

[0025] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please refer to Figures 1 to 4 As shown, an impregnation device for producing graphite electrodes according to this utility model includes a heating tank 5 and a support point switching mechanism 4, wherein the support point switching mechanism 4 is provided at the bottom of the heating tank 5.

[0027] The support point switching mechanism 4 includes a rotation drive 403, a transmission belt 407 and two sets of support switching components. The bottom of the heating pool 5 is rotatably connected to two sets of the support switching components. One support switching component is connected to the other support switching component via the transmission belt 407. The rotation drive 403 is driven to one of the support switching components.

[0028] The support switching assembly includes a rotating shaft 404, a first cam 401, and a second cam 402. The rotating shaft 404 is rotatably connected to the bottom of the heating pool 5. Several first cams 401 are arranged from left to right on the rotating shaft 404. A second cam 402 is provided between each of the first cams 401. The second cams 402 are all provided outside the rotating shaft 404. One rotating shaft 404 is connected to another rotating shaft 404 through the transmission belt 407. The rotation drive 403 is driven to one of the rotating shafts 404.

[0029] The working principle of this utility model is as follows: In actual production and use, when it is necessary to impregnate the graphite electrode 1, the cylindrical graphite electrode 1 can be placed inside the heating tank 5, so that the graphite electrode 1 is submerged in the impregnation liquid in the heating tank 5, and several first cams 401 are placed to support the bottom of the graphite electrode 1, so that the impregnation liquid can better penetrate the bottom of the graphite electrode 1. At the same time as impregnation, the heating tank 5 can be operated to heat the impregnation liquid, thereby increasing the fluidity of the impregnation liquid. When it is necessary to adjust the position of the first cams 401... To achieve better impregnation, the rotating drive 403 can be operated to drive a rotating shaft 404 to rotate. This causes the rotating shaft 404 to drive another rotating shaft 404 to rotate synchronously via the transmission belt 407. Subsequently, the rotating shaft 404 drives the first cam 401 and the second cam 402 to rotate, so that the second cam 402 supports the remaining positions at the bottom of the graphite electrode 1 and releases the original support of the first cam 401 on the bottom of the graphite electrode 1, allowing the impregnation liquid to better penetrate the original support position of the first cam 401.

[0030] Furthermore, the first cam 401 is provided with a first support portion 406, and the second cam 402 is provided with a second support portion 405. The first support portion 406 on the first cam 401 and the second support portion 405 on the second cam 402 are alternately arranged on the rotating shaft 404.

[0031] As can be seen from the above description, the first support portion 406 on the first cam 401 and the second support portion 405 on the second cam 402 can be rotated and flipped by the rotation of the rotating shaft 404, thereby realizing the replacement of the bottom support point of the graphite electrode 1.

[0032] Furthermore, it also includes a shielding cover 3, which is disposed opposite to the upper part of the heating pool 5, and the shielding cover 3 is slidably connected to the upper part of the heating pool 5.

[0033] As can be seen from the above description, when it is necessary to impregnate the graphite electrode 1, the shielding cover 3 can be used to shield the upper part of the heating pool 5, reduce the heat loss inside the heating pool 5, and reduce the probability of the impregnation liquid solidifying.

[0034] Furthermore, it also includes a handle 2, and the upper part of the cover 3 is fixedly connected with the handle 2.

[0035] As can be seen from the above description, it is advantageous to slide the cover 3 using the handle 2.

[0036] Furthermore, it also includes support feet 6, and several support feet 6 are fixedly connected to the bottom of the heating pool 5.

[0037] As can be seen from the above description, it is beneficial to make the device operate more stably.

[0038] Furthermore, it also includes a valve body 8, and the lower part of the heating pool 5 is provided with an outlet 7, and the valve body 8 is provided inside the outlet 7.

[0039] As can be seen from the above description, when it is necessary to discharge the impregnation liquid in the heating tank 5, the valve body 8 can be operated to open the outlet 7, thereby allowing the impregnation liquid to be discharged from the outlet 7.

[0040] Furthermore, it also includes a PLC controller, which is electrically connected to the heating pool 5 and the support point switching mechanism 4 respectively.

[0041] As can be seen from the above description, it is beneficial to adjust the parameters of the impregnation device for producing graphite electrode 1 through the PLC controller, and to make it more convenient for operators to operate the impregnation device for producing graphite electrode 1.
