Description

Technical Field

[0001] The utility model relates to the technical field of pouring cup production equipment, and more specifically to a sintering furnace dust removal mechanism for pouring cup processing. Background Art

[0002] During the manufacturing process of the pouring cup, the pouring cup can be solidified or welded by a sintering furnace. In the casting preparation stage, the pouring cup usually needs to be placed in a sintering furnace for final processing. This step ensures that the internal structure of the pouring cup is solidified and intact, and at the same time, it can remove possible impurities inside, which ensures that the pouring cup can stably withstand high temperatures and metal flow pressure in the subsequent casting process. During the solidification and welding process of the pouring cup in the sintering furnace, dust removal equipment or appropriate emission control mechanisms are usually required. This is mainly because the sintering furnace will produce smoke and gas during the heating process, including some solid particles and dust. If these emissions are not properly controlled and handled, they are likely to cause pollution to the surrounding environment and affect the health of the workers.

[0003] The Chinese authorized utility model patent with announcement number CN214261212U discloses a sintering furnace that is convenient for environmentally friendly treatment of flue gas. The sintering furnace provides a guide pipe on the top of the sintering furnace body to guide the high-temperature flue gas generated when the sintering furnace body is in operation to a three-way valve, and the flue gas and air are transported to the dust removal device together through the operation of the fan. The filter intercepts large pieces of dust and debris in the flue gas, and the high-efficiency filter intercepts most of the dust impurities. The odor in the flue gas is removed through the activated carbon layer, and finally the last dust that has not been removed is adsorbed by the electrostatic dust removal device.

[0004] When the dust removal mechanism in the above patent is applied to the sintering furnace for pouring cup processing in this patent, since multiple filters and activated carbon layers are welded in the dust removal device, they cannot be replaced regularly. In actual implementation, the multi-layer filter located at the front end of the electrostatic dust removal device is prone to blockage of the surface of the filter due to solid particles and dust in the flue gas during long-term use, which will greatly limit the ability of airflow to pass through, causing the subsequent high-efficiency filter and activated carbon layer to bear higher particulate matter and pollutant loads, which will shorten the service life of subsequent filter media because they need to deal with more pollutants, and the value of subsequent filter media is often higher than that of the front-end filter. Long-term blockage will also cause the internal pressure of the dust removal device to increase, thereby increasing the risk of wear and damage to the filter and activated carbon layer. This additional pressure and pollutant load may accelerate its failure, and the partitions and dust drawers set therein are also prone to the collected dust being raised again and mixed with the flue gas when the equipment is performing dust removal operations.

[0030] See also Figure 3-4 The dust removal box body 1 is provided with a slide groove 103, and the air guide plate 2 is provided with a slide groove 201. The movable filter frame 3 is slidably connected to the slide groove 103 and the slide groove 201.

The left and right ends of the movable filter frame 3 are provided with a plurality of spherical grooves distributed at equal intervals, and balls 303 are installed in the spherical grooves. The balls 303 are slidably connected to the slide groove 201 and the slide groove 103.

When the magnetic poles of the end of the movable strong magnetic block 13 and the fixed strong magnetic block 301 close to each other are in opposite states, the movable filter frame 3 will be tightly fitted on the inner wall of the dust removal box 1 through the magnetic attraction force. When the magnetic poles of the end of the movable strong magnetic block 13 and the fixed strong magnetic block 301 close to each other are in the same state, the movable filter frame 3 will be easily slid out from the slide groove 201 and the fixed strong magnetic block 301 through the magnetic repulsion force.

[0033] Working principle: When the dust removal mechanism is performing dust removal operations, the solid particles and dust produced during the operation of the sintering furnace are intercepted and adsorbed in multiple layers through the air guide channel composed of multiple air guide plates 2 and the primary filter 4, fine filter 5, activated carbon layer 6 and electrostatic adsorption component 7 located on the air guide channel; when the primary filter 4, fine filter 5, activated carbon layer 6 and electrostatic adsorption component 7 are regularly cleaned and replaced, it is only necessary to control the motor to start, so that its output shaft rotates to drive the rotating shaft 10 and the driven rotating drum 12 to rotate 180°, and the magnetic pole direction of the active strong magnetic block 13 is reversed, so that the magnetic poles of the active strong magnetic block 13 and the fixed strong magnetic block 301 that are close to each other are in the same state, and each active filter frame 3 can be easily taken out of the dust removal box 1, and the primary filter 4, fine filter 5, activated carbon layer 6 and electrostatic adsorption component 7 can be easily cleaned and replaced. 5. When the activated carbon layer 6 or the electrostatic adsorption component 7 is cleaned and needs to be reassembled, it is only necessary to slide the movable filter frame 3 along the slide groove 201 or the slide groove 1 103 and make it fit tightly with the inner wall of the dust removal box 1. In this state, the sealing layer blocks the openings of the slide groove 103 and the slide groove 201, and then the motor is controlled to start again so that the magnetic poles of the end of the movable strong magnetic block 13 and the fixed strong magnetic block 301 that are close to each other are in opposite states, and the assembly can be completed. Compared with the prior art, the utility model can facilitate the regular removal of the primary filter, fine filter, activated carbon layer and electrostatic adsorption component through the movable filter frame for cleaning or replacement, which can prevent the filter surface from being blocked by solid particles and dust, reduce the risk of wear and damage to the filter and the activated carbon layer, and effectively ensure the dust removal effect of the equipment.
