Description

Technical Field

[0001] This invention belongs to the field of ductile iron production technology, specifically relating to a vibratory boiling cooler for producing ductile iron manhole covers. Background Technology

[0002] Ductile iron manhole covers are a type of ductile iron product. Ductile iron undergoes spheroidization and inoculation treatment to obtain spheroidal graphite, effectively improving the mechanical properties of cast iron, particularly its plasticity and toughness. This results in strength higher than carbon steel, and its overall performance is close to that of steel. Based on these superior properties, it has been successfully used to cast parts subject to complex stresses and requiring high strength, toughness, and wear resistance. Currently, the production and processing of ductile iron manhole covers requires drying. However, conventional drying equipment is too slow, consumes too much energy, and causes some pollution, affecting production efficiency and increasing labor intensity.

[0003] To address this, patent specification CN116174689A discloses a vibratory boiling cooler for producing ductile iron manhole covers. The cooler includes a machine body, with two connecting seats fixedly connected to the inner wall of the top of the machine body. A grid plate is provided on one side of each connecting seat. A vibration motor is fixedly connected to the side wall of the machine body, and a connecting plate is fixedly connected to the output shaft end of the vibration motor. A transmission rod is fixedly connected to the side wall of the connecting plate, extending through the right connecting seat into the interior of the machine body and fixedly connected to the side wall of the grid plate. A buffer ring is fixedly connected to the inner wall of the right connecting seat, and a support plate is fixedly connected to the inner wall of the machine body below the grid plate. This vibratory boiling cooler for producing ductile iron manhole covers can improve the heat dissipation efficiency of the manhole covers, while reducing energy consumption, environmental pollution, and labor intensity, thereby ensuring production efficiency.

[0004] However, this type of vibratory boiling cooler for producing ductile iron manhole covers has shortcomings. First, it cannot achieve automatic feeding and discharging of ductile iron manhole covers; second, it suffers from steam backflow. Therefore, it needs to be optimized and improved. Summary of the Invention

[0009] Furthermore, in the aforementioned vibratory boiling cooler for producing ductile iron manhole covers, the opening of the cover is rectangular, and the upper end of the cover is provided with an arc-shaped sealing wall that facilitates contact with the arc-shaped sealing cover.

[0010] Furthermore, in the aforementioned vibratory boiling cooler for producing ductile iron manhole covers, the ductile iron manhole cover has several arc-shaped grooves near its outer edge to facilitate being hooked by mechanical grippers.

[0011] Furthermore, in the aforementioned vibratory boiling cooler for producing ductile iron manhole covers, the hook portion of the mechanical gripper is a round rod portion that facilitates insertion into the arc-shaped groove. After the ductile iron manhole cover is gripped by the mechanical gripper, it can shake to a certain extent under the blowing of the airflow below.

[0012] Furthermore, in the aforementioned vibratory boiling cooler for producing ductile iron manhole covers, the rotating plate is provided with several weight-reducing perforated holes.

[0013] Furthermore, in the aforementioned vibratory boiling cooler for producing ductile iron manhole covers, a condenser is externally connected to the condenser connecting pipe.

[0014] Furthermore, in the aforementioned vibratory boiling cooler for producing ductile iron manhole covers, both the air outlet pipe and the steam guide pipe are equipped with Tesla cavities to prevent backflow.

[0015] The beneficial effects of this invention are:
