Description

Technical Field

[0001] The utility model relates to the technical field of coated sand processing, in particular to cooling equipment for coated sand processing. Background Art

[0002] Coated sand is a molding sand or core sand with a layer of solidified resin film on the surface of the sand grains before molding. The finished coated sand generally has a higher temperature when it is just produced. When the finished coated sand is discharged from the sand mixer, the temperature is usually around 100 degrees. It needs to be quickly cooled and put into a storage bag. In the prior art, the newly produced coated sand is often placed in an air environment for natural cooling. This method is used to cool the finished coated sand, but the cooling time is too long, the cooling efficiency is low, and it is time-consuming and labor-intensive.

[0003] To this end, we propose a cooling device for coated sand processing. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cooling device for coated sand processing, including a cooling box, a feed port and a discharge port. A heat dissipation net is fixedly connected to the top of the inner cavity of the cooling box, and a cooling component is provided on the outer side and the inner cavity of the cooling box. The cooling component includes a water storage tank, and cooling circulation pipes are fixedly connected on both sides of the water storage tank. A water pump and a plurality of micro heat exchangers are fixedly connected to the cooling circulation pipes. A blower is fixedly connected to the left wall of the cooling box, and an air supply pipe is fixedly connected to the air outlet end of the blower, and an air nozzle is fixedly connected to the air supply pipe. A filter is provided on the inner cavity of the cooling box near the air nozzle, and a stirring component is also provided on the cooling box.

[0006] Preferably, the stirring assembly includes a driving motor, the output shaft end of the driving motor is fixedly connected to a stirring shaft, and the side wall surface of the stirring shaft is fixedly connected to a stirring rod.

[0007] Preferably, the feed port is fixedly connected to the heat dissipation net and the feed port is communicated with the inner cavity of the cooling box.

[0009] Preferably, the cooling circulation pipe is fixedly connected to the four side walls of the cooling box.

[0010] Preferably, the air supply pipe is a "T"-shaped structure.

[0011] Beneficial Effects

[0012] The utility model provides a cooling device for coated sand processing, which has the following beneficial effects:

[0013] (1) The cooling equipment for coated sand processing starts the blower, and the gas is ejected through the air nozzle on the air supply pipe to dissipate the heat of the coated sand in the inner cavity of the cooling box. Part of the hot air is dissipated from the heat dissipation net. At the same time, the water pump is started, and the cooling water in the water storage tank circulates along the cooling circulation pipe and then flows back to the inner cavity of the water storage tank. In this process, the cooling water absorbs the heat from the side wall of the cooling box and reduces the cooling water temperature again through heat exchange with multiple micro heat exchangers. The internal and external heat dissipation can achieve better heat dissipation effect, reduce cooling time, and improve cooling efficiency.

[0014] (2) The cooling device for processing coated sand is configured to turn on the driving motor to rotate the stirring rod on the stirring shaft, thereby quickly stirring the coated sand in the inner cavity of the cooling box, thereby breaking up the agglomerated coated sand and ensuring the subsequent cooling effect of the coated sand.
