Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to a high-efficiency double-disc stirring cooler. Background Technology

[0002] Double-disc agitator coolers are foundry equipment used in foundry workshops to cool spent sand. High-pressure air blowers bring the spent sand to a boiling state, and thorough agitation ensures uniform temperature, humidity, and composition, completing premixing while cooling. Because a large amount of dust is generated during agitation and air blowing, existing double-disc agitator coolers typically include a dust collection box, using a cyclone dust collector to collect the dust. To prevent molding sand from being sucked into the cyclone dust collector, a dust filter is installed at the inlet of the dust collection box. However, in actual operation, although molding sand does not enter the cyclone dust collector, it is easily adsorbed onto the dust filter, causing blockage and affecting dust removal and molding sand mixing. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency dual-disc stirring cooler to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency double-disc stirring cooler, comprising a cooler tank, a connecting pipe at the top of the cooler tank, the cooler tank being connected to a dust collection box via the connecting pipe, a filter assembly at the inlet end of the connecting pipe, the filter assembly comprising a filter plate, a connecting rod rotatably disposed in the middle of the filter plate, a servo motor being connected to one end of the connecting rod away from the cooler tank, and an mounting plate being sleeved on the other end, two scrapers being slidably disposed on the side of the mounting plate near the filter plate, the two scrapers being arranged on both sides of the connecting rod and slidably connected to the surface of the filter plate, and a brush being embedded on the side of the scraper near the filter plate.

[0005] The following improvements are made in this application: the mounting plate has a cavity, and a cylinder is provided in the cavity. One end of the cylinder is connected to the inner wall of the cavity by a spring, and the other end extends through the mounting plate to the outside. A channel is provided on the side of the mounting plate near the filter plate, and the channel communicates with the cavity. A sliding rod is provided on the side of the scraper away from the brush, and the other end of the sliding rod passes through the channel and is connected to the cylinder.

[0006] The following improvements are made in this application: the end of the cylinder located outside the mounting plate is provided with a hemispherical protrusion, and the inner wall of the pipe is provided with a plurality of abutment blocks that cooperate with the hemispherical protrusion.

[0007] The following improvements are made in this application: the slide rod is slidably connected to the inner wall of the channel, and the length of the channel is consistent with the radius of the hemispherical protrusion.

[0008] The present application makes the following improvement: the filter plate has a sandwich layer, and a perforated plate is rotatably disposed within the sandwich layer. The perforated plate has a through hole in its center that mates with a connecting rod. By providing a sandwich perforated plate within the filter plate, the size of the filter pores can be adjusted by rotating the perforated plate.

[0009] The following improvement is made in this application: the perforated plate has a circular structure, and an adjusting rod is installed on its outer ring. The adjusting rod passes through the filter plate, and the filter plate has an arc-shaped groove for the adjusting rod to move. Rotating the adjusting rod along the arc-shaped groove causes the perforated plate to rotate, making the filter holes on the perforated plate and the filter plate interlaced, forming new filter holes of different sizes to ensure the filtration effect.

[0010] Compared with the prior art, this utility model provides a high-efficiency dual-disc stirring cooler, which has the following beneficial effects:

[0011] This invention adds a scraper to the filter plate to clean the molding sand adsorbed on it, ensuring normal filtration and preventing dust removal inside the cooler from being affected by filter plate blockage. The cleaned molding sand falls back into the cooler and is premixed by thorough stirring. A servo motor drives the connecting rod to rotate, which in turn drives the mounting plate to rotate, causing the brush to rotate and clean the surface of the filter plate, scraping off the molding sand adsorbed on the filter plate. As the mounting plate rotates, the cylinder rotates with it, and the hemispherical protrusion squeezes against the abutment block on the inner wall of the pipe. With the help of a spring, the cylinder moves in a telescopic motion, causing the scraper and brush to reciprocate left and right while rotating and cleaning, generating friction with the surface of the filter plate, further improving the cleaning effect of the filter plate.
