Description

Technical Field

[0001] The utility model relates to the technical field of ductile iron castings, in particular to a dust collecting device used in the production of ductile iron castings. Background Art

[0002] Ductile iron castings are a type of high-strength cast iron material. Ductile iron castings are often used to cast some parts with higher stresses because their strength is close to that of steel. Ductile iron castings will generate a lot of dust during the production process, so a dust collection device is required to collect the dust.

[0003] When using a dust collecting device, most of the existing dust collecting devices absorb dust through a fan, and this dust collecting method cannot absorb and concentrate dust well when the dust contains particulate matter, and a small amount of dust will escape through the feed port, reducing the dust collecting efficiency of the dust collecting device. When the dust collecting device is used for a long time, most of the existing dust collecting devices do not have a collection device, resulting in dust that cannot be adsorbed by the filter being stored in the ventilation duct, reducing the dust collecting efficiency of the dust collecting device. Therefore, a dust collecting device for ductile iron casting production is proposed to solve the above-mentioned problems. Utility Model Content

[0028] Both atomizing nozzles 12 are connected to the water pipe;

[0029] The bottom of the auxiliary pipe 10 is arranged in a trapezoidal shape, and the number of the atomizing nozzles 12 is two and they are arranged symmetrically in front and back;

[0030] By setting the auxiliary pipe 10 in a trapezoidal shape, the absorption range is increased;

[0031] The left wall and the right wall of the inner cavity of the housing 1 are fixedly connected to a base 13, and a flow hole is opened inside the base 13;

[0032] Through the flow holes, water on the top of the base 13 can fall to the bottom by gravity;

[0033] The bottom wall of the inner cavity of the shell 1 is arranged in an inclined surface, and a first collecting block 14 is fixedly connected to the inside of the shell 1;

[0034] The inclined surface allows water on the bottom wall of the inner cavity of the housing 1 to flow into the first collecting block 14;

[0035] The housing 1 has a flow channel adapted to the first collecting block 14, and two auxiliary pipes 10 are arranged symmetrically.

[0036] Through the two auxiliary pipes 10, most of the dust inside the housing 1 can be absorbed;

[0037] The processing device 11 includes a main pipe 1101, two filter screens 1102 are slidably connected inside the main pipe 1101, a fan 1103 located on the top of the filter screen 1102 is fixedly connected inside the main pipe 1101, and a second collection block 1104 is slidably connected inside the main pipe 1101;

[0038] Dust can be filtered through the filter 1102.

[0039] Working principle:

[0040] Step 1: Start the dual-axis motor 2, so that the output ends on both sides of the dual-axis motor 2 drive the horizontal axis 3 to rotate, and the two horizontal axes 3 rotate to drive the two first gears 4 to rotate, and then the two first gears 4 drive the two second gears 6 to rotate, so that the two second gears 6 drive the two threaded rods 7 to rotate through the two vertical axes 5, and then the two threaded rods 7 drive the two lifting blocks 8 to drive the cover block 9 to move up, and then place the material inside the shell 1, and rotate the dual-axis motor 2 in the opposite direction, so that the cover block 9 covers the top of the shell 1;

[0041] Step 2: When processing the material, start the fan 1103, so that the fan 1103 exhausts air into the housing 1 through the main pipe 1101 and the auxiliary pipe 10, so that the dust inside the housing 1 reaches the filter 1102 through the auxiliary pipe 10 and the main pipe 1101, and the lighter dust is filtered by the filter 1102, while the heavier dust falls into the second collection block 1104 due to gravity;

[0042] Step 3: Start the atomizing nozzle 12 to spray toward the interior of the shell 1, so that part of the dust that is not collected by the auxiliary pipe 10 is weighted by water molecules and falls to the outside of the base 13 by gravity. Then, the liquid containing dust flows into the interior of the first collecting block 14 through the flow groove through the flow hole of the base 13 and the inclined surface of the bottom wall of the inner cavity of the shell 1, thereby increasing the dust collection efficiency inside the shell 1.
