Description

Technical Field

[0001] The invention relates to the technical field of rotary heating furnaces, and in particular to an operating method of a rotary heating furnace unloading device. Background Art

[0002] A rotary heating furnace is used to process refractory balls. When the existing rotary heating furnace is in use, the transportation of the processed refractory balls may increase the kinetic energy of the refractory balls during transportation due to the large height difference between the equipment and the ground. The refractory balls may be deformed when contacting the bottom of the equipment, affecting the production quality of the refractory balls. For this reason, we propose an operating method for a rotary heating furnace unloading device. Summary of the invention

[0003] In view of the above problems, the present invention provides an operating method for a rotary heating furnace unloading device, which has the function of preventing the production quality of refractory balls from being affected during the transportation of finished products.

[0004] The technical solution of the present invention is:

[0005] A method for operating a rotary heating furnace unloading device, comprising a device body, a ball outlet tube being fixedly connected to the lower surface of the device body, a spiral slide being arranged inside the device body, a support rod being fixedly connected to the inner surface of the spiral slide, a support shaft being fixedly connected to one end of the support rod, a fixed shaft being fixedly connected to the inner surface of the spiral slide, a shaft sleeve being movably connected to the outer surface of the fixed shaft, a buffer plate being fixedly connected to the lower surface of the shaft sleeve, the buffer plate comprising an upper dividing plate and a lower dividing plate, a connecting shaft being arranged inside the buffer plate.

[0006] The working principle of the above technical solution is as follows:

[0007] During the use of the device, the processed refractory balls are placed on the upper end of the spiral slide, so that they slide downward along the spiral slide. The refractory balls will contact the buffer plate while sliding inside the spiral slide. Depending on the size of the refractory balls, the lower dividing plate will be driven to deflect below the upper dividing plate, or the buffer plate will be driven to deflect on the lower surface of the sleeve, thereby consuming the kinetic energy generated during the transportation of the refractory balls, and preventing the refractory balls from being deformed due to contact and collision with the funnel at one end of the spiral slide due to the large kinetic energy after being transported to the bottom of the spiral slide, thereby facilitating the transportation of the refractory balls.

[0008] In a further technical solution, a torsion spring is arranged between the fixed shaft and the sleeve, and one end of the torsion spring is fixedly connected to the outer surface of the fixed shaft, and the other end of the torsion spring is fixedly connected to the inner surface of the sleeve.

[0009] The torsion spring is used to keep the buffer plate with the force to return to its original position after being deflected by an impact.

[0010] In a further technical solution, the upper dividing plate and the lower dividing plate are movably connected via a connecting shaft, and the buffer plates are distributed in the middle section of the spiral slide and near the end of the spiral slide.

[0011] The buffer plate is divided into an upper sub-plate and a lower sub-plate which are movably connected, so that it can adapt to the size of the refractory ball. At the same time, it is distributed in the lower middle section of the spiral slide to prevent the refractory ball from being stuck due to low initial kinetic energy.

[0012] In a further technical solution, a funnel is provided at the lower end of the spiral slide, and the spiral slide is connected to the upper end of the ball outlet tube through the funnel.

[0013] The funnel at the lower end of the spiral slide is used to receive the refractory balls and transport them to the inside of the ball outlet pipe, so as to facilitate the collection of the refractory balls.

[0014] In a further technical solution, the inner surface of the ball outlet tube is movably connected to an extension tube, one end of the extension tube is fixedly connected to a connecting tube, the outer surface of one end of the extension tube is fixedly connected to a slider, a sliding groove is provided on the inner wall of the lower end of the ball outlet tube, a return spring is fixedly connected to the inner wall of the sliding groove, one end of the return spring is fixedly connected to a pressure plate, and a slot is provided on one side of the pressure plate.

[0015] The connecting tube is rotated to drive the extension tube and the slider to rotate, so that the slider slides in the quarter-circle groove, and then the connecting tube is pushed through the extension tube to drive the slider to move to the quarter-circle groove at the other end of the slider, and then the slider is rotated to correspond to the slot. During this process, the slider will compress the return spring through the pressure plate and make it subject to force, and then the slider will be pushed into the inside of the slot through the pressure plate under the action of the return spring force, and the slider is restricted from detaching from the inside of the slot under the action of the pressure plate, so as to facilitate the adjustment of the extension length of the ball outlet tube.

[0016] In a further technical solution, both ends of the slider are provided with a quarter-circle groove, and the return spring and the pressure plate are both located inside the groove.

[0017] The quarter-circular grooves at both ends of the slider are used to connect the tube to drive the slider to rotate through the extension tube, and then further limit the separation of the slider and the slot through the return spring and the pressure plate, so as to facilitate the adjustment of the length of the extension tube inside the ball outlet tube.

[0018] In a further technical solution, the clamping groove is provided on the inner wall of the ball outlet tube and is connected to each other through a quarter-circular groove and a slide groove, and the clamping groove and the slide groove are matched with the slider.

[0019] The extension tube controls the slider to slide from one end of the slide slot to the other end. After two rotations, the slider is clamped into the slot through the pressure plate and the separation of the slider and the slot is limited, which is convenient for adjusting the length of the connecting tube.

[0020] The beneficial effects of the present invention are:

[0021] 1. Through the spiral slideway and the buffer plate inside it, the kinetic energy generated during the transportation of the refractory balls is reduced to avoid deformation after impact, which affects the production quality of the refractory balls;

[0022] 2. The connecting tube is rotated to drive the extension tube and the slider to rotate, so that the slider slides in the quarter-circle groove, and then the connecting tube is pushed through the extension tube to drive the slider to move to the quarter-circle groove at the other end of the slider, and then the slider is rotated to correspond to the slot, and the slider is pushed into the inside of the slot through the pressure plate, and the slider is restricted from detaching from the inside of the slot under the action of the pressure plate, so as to facilitate the adjustment of the extension length of the ball outlet tube.

Depending on the size of the refractory balls, the lower dividing plate 9 will be driven to deflect below the upper dividing plate 8, or the buffer plate 10 will be driven to deflect on the lower surface of the sleeve 6, thereby consuming the kinetic energy generated during the transportation of the refractory balls, and preventing the refractory balls from being deformed due to contact and collision with the funnel at one end of the spiral slide 2 due to the large kinetic energy after being transported to the bottom of the spiral slide 2, thereby facilitating the transportation of the refractory balls.
