Description

Technical Field

[0001] This utility model relates to the field of coated sand heating, and more specifically, it relates to a coated sand heating device. Background Technology

[0002] Coated sand is molding sand or core sand with a solid resin film coated on the surface of the sand grains before molding. There are two coating processes: cold coating and hot coating. In the hot coating process, the sand is preheated to a certain temperature, resin is added to melt it, and the mixture is stirred to coat the surface of the sand grains with resin. Hexamethylenetetramine aqueous solution and lubricant are added, and the sand is then cooled, crushed, and sieved to obtain coated sand. Therefore, a heating device is required to heat the coated sand. Existing heating devices are generally box-shaped structures, which heat the coated sand through heating structures installed on the box. However, because the heating structure is fixed in position, the heating effect of the coated sand in different positions in the box is different, which will cause uneven heating of the coated sand and affect its use. At the same time, there may be clumps inside the coated sand, and existing heating devices cannot break up and remove the clumps, thus affecting the long-term use of the coated sand.

[0011] The present invention is further configured such that the stirring rod is provided with a cutting blade, the cutting blade is fixedly connected to the stirring rod, and multiple cutting blades are provided, so as to cut the agglomerated coated sand through the cutting blades.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a coated sand heating device, which has the following beneficial effects: 1. This utility model, by setting a heating structure, when heating the coated sand, adds the coated sand into the placement groove, and activates the electric push rod set on the fixing frame. The extension of the electric push rod drives the second heating wire into the placement groove, thereby heating the coated sand at the edge of the placement groove through the first heating wire set in the mounting hole on the main body box, and heating the coated sand in the middle through the second heating wire, thus facilitating the uniform heating of the coated sand and making it easier to use.

[0013] 2. This utility model, by setting a rotating structure, after the coated sand is heated for a certain period of time, the electric push rod retracts and drives the second heating wire to leave the mounting groove. The motor set on the cross frame drives the rotating rod to rotate, thereby stirring the coated sand through the stirring rod set on the rotating rod, thus changing the original position of the coated sand. After the stirring is completed, the second heating wire is re-inserted into the placement groove, which facilitates the full heating of the coated sand and facilitates the subsequent heating and use of the coated sand.

[0014] 3. This utility model, by setting a rotating frame on a rotating rod and a cutting blade on a stirring rod, allows the rotating rod to rotate via a motor during the heating process of the coated sand. This rotation, in turn, moves the stirring rod, stirring the coated sand while simultaneously cutting the clumps of coated sand. This facilitates the breaking up of the clumps. Once the coated sand is heated, it is discharged through a discharge pipe. The rotating frame, driven by the rotating rod, scrapes off the coated sand adhering to the side wall of the placement trough in the main body box, thus reducing waste of the coated sand.

[0023] Please see Figures 1-5As one embodiment of heating and treating coated sand: The main body box 1 has mounting holes 12 on its edge within the placement groove 2.
