The charge proportioner of the calcium carbide furnace is a device for remote proportioning according to production needs. In the production of calcium carbide, the accuracy of the charge proportion directly affects the quality of calcium carbide products and the stability of production. The charge proportion of the calcium carbide furnace is crucial to the production of calcium carbide.

[0023] See also Figure 1-Figure 5 In order to solve the problem that when the existing blue coke and lime are added into the furnace in a certain proportion, the lime may agglomerate and remain, which may cause blockage, not only affecting the continuity and stability of calcium carbide production, but also causing damage to the equipment, greatly affecting the production efficiency, the following preferred technical solutions are provided:

[0024] A high-yield and low-consumption charge ratio unloading structure for a calcium carbide furnace comprises a unloading assembly 2 installed on one side of the calcium carbide furnace 1, the unloading assembly 2 comprises an upper loading block 21, and a lower loading block 22 installed at the lower end of the upper loading block 21, an expansion joint 23 is fixedly connected to the lower end of the lower loading block 22, an end of the expansion joint 23 away from the lower loading block 22 is connected to the inner cavity of the calcium carbide furnace 1, a feed port 24 is provided at the upper end of the upper loading block 21, a motor 25 is installed on one side of the upper loading block 21, an output end of the motor 25 passes through the inner wall of the loading block 21, and a breaking rod 26 is fixedly connected to the end through which the breaking rod 26 passes, a breaking paddle 27 is fixedly connected to the outer wall of the breaking rod 26, and a filter screen 28 is arranged at the lower end of the breaking rod 26.

[0025] The upper mounting block 21 , the lower mounting block 22 and the expansion joint 23 are interconnected. The filter screen 28 is a component made of beryllium bronze and has elasticity. The shortest distance between the filter screen 28 and the breaking rod 26 is less than the length of the breaking paddle 27 .

[0026] Side connecting blocks 29 are provided on both sides of the filter screen 28, the inner wall of the side connecting block 29 is fixedly connected to the inner wall of the lower mounting block 22, the outer wall of the side connecting block 29 is provided with a slide groove 210, the inner wall of the slide groove 210 is slidably connected with a slider 211, the slider 211 is fixedly connected to the filter screen 28, the lower end of the slider 211 is fixedly connected with a vibration spring 212, the lower end of the vibration spring 212 is fixedly connected to the bottom plate of the cavity of the slide groove 210, when the vibration spring 212 is in a compressed state, the breaking rod 26 contacts the filter screen 28.

[0027] Specifically, during the production of calcium carbide, blue coal and lime mixed in a certain ratio can be poured into the cavity of the upper loading block 21 through the feed port 24, and the motor 25 is driven. The output end of the motor 25 drives the breaking rod 26 to rotate, and drives the breaking paddle 27 to break up the poured raw materials to reduce agglomeration. The broken raw materials will be filtered through the filter 28 to prevent the agglomerated raw materials from continuing to be fed. Since the filter 28 is a component made of beryllium bronze, it has elasticity, and the closest distance between the filter 28 and the breaking rod 26 is less than the length of the breaking paddle 27, whenever the breaking When the paddle 27 contacts the filter screen 28, the filter screen 28 will be squeezed, causing the filter screen 28 to bounce up the agglomerated raw materials and continue to break them up, effectively avoiding blockage, and the filtered raw materials will be introduced into the cavity of the calcium carbide furnace 1 through the expansion joint 23 for reaction, further avoiding blockage, ensuring production efficiency, and solving the problem that when the existing lignite and lime are added to the furnace in a certain proportion, blockage may occur due to lime agglomeration and retention, which will not only affect the continuity and stability of calcium carbide production, but may also cause damage to the equipment, greatly affecting the production efficiency.

By utilizing the reaction force of the vibration spring 212, the slider 211 will drive the filter screen 28 to more efficiently bounce up the agglomerated raw materials, with significant effect.

[0029] To sum up: the driving motor 25, the output end of the motor 25 drives the breaking rod 26 to rotate, and drives the breaking paddle 27 to break up the poured raw materials to reduce agglomeration. The broken raw materials will be filtered through the filter screen 28 to prevent the agglomerated raw materials from continuing to be discharged. Since the filter screen 28 is a component made of beryllium bronze, it has elasticity, and the closest distance between the filter screen 28 and the breaking rod 26 is less than the length of the breaking paddle 27, therefore, whenever the breaking paddle 27 contacts the filter screen 28, the filter screen 28 will be squeezed, so that the filter screen 28 will bounce up the agglomerated raw materials. When the breaking paddle 27 contacts the filter screen 28, the filter screen 28 will drive the slider 211 to move down in the slide groove 210, so that the slider 211 presses the vibration spring 212, and the reaction force of the vibration spring 212 will be used to drive the filter screen 28 to bounce up the agglomerated raw materials more efficiently through the slider 211, continue to break them up, and effectively avoid blockage.
