Description

Technical Field

[0001] This utility model belongs to the field of resin sand cooling technology, and in particular relates to a resin sand cooling device. Background Technology

[0002] In the casting industry, resin sand is a commonly used molding material. After mixing and heating, the temperature of resin sand is usually high. If subsequent molding operations are carried out directly, the excessively high temperature will affect the molding performance of the resin sand, such as causing the binder to fail prematurely, thereby reducing the precision and quality of the casting. Therefore, cooling treatment is required.

[0003] Currently, resin sand can be cooled by natural air drying or simple cylindrical or box-type cooling equipment. Natural air drying is heavily dependent on environmental conditions and has extremely low cooling efficiency. Cylindrical or box-type cooling equipment requires placing the material in a container, cooling it, and then transporting it out. Neither of these cooling methods can meet the needs of large-scale industrial production. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a resin sand cooling device. By setting up a conveying mechanism, resin sand can be conveyed. During the conveying process, an air supply mechanism delivers air to the air collection box and discharges it through the exhaust port. The air acts on the resin sand on the conveyor belt to cool it. Several exhaust ports are evenly arranged to meet the uniform cooling requirements, avoid the trouble of frequent material transfer, and meet the needs of large-scale industrial production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A resin sand cooling device includes a frame, a conveying mechanism, and an air supply mechanism. Support legs are fixed to the bottom of the frame. The conveying mechanism, comprising a drive roller, a geared motor, a driven roller, and a conveyor belt, is mounted on the frame. A drive roller is fixed to the inner left side of the frame via a rotating shaft, and a driven roller is fixed to the inner right side of the frame via a rotating shaft. The drive roller and the driven roller are connected by a conveyor belt. A geared motor connected to the left rotating shaft is mounted on the front of the frame. At least two first mounting frames are mounted on the frame. Each first mounting frame has a U-shaped structure. An air collection box is fixed to the bottom of the horizontal end of each first mounting frame, located above the conveyor belt. Several exhaust holes are equidistantly spaced on the bottom of the air collection box. An air supply mechanism, comprising a blower, an inlet pipe, a main air pipe, and branch air pipes, is located on the upper horizontal end of each first mounting frame. A blower is installed on the upper side of the frame. An air inlet pipe is installed at the air inlet of the blower, and a main air pipe is fixed at the air outlet of the blower. Several branch air pipes are fixed at equal intervals on the bottom side of the main air pipe, and all branch air pipes extend into the inner cavity of the air collection box. A second mounting frame is installed on the upper left side of the frame. The second mounting frame has a "U" shaped structure. A leveling mechanism is provided on the bottom side of the horizontal end of the second mounting frame. A controller is installed on the front side of the frame. The output end of the controller is electrically connected to the input end of the geared motor and the blower, respectively. The resin sand can be conveyed by the conveying mechanism. During the conveying process, air is delivered to the air collection box by the air supply mechanism and discharged through the exhaust port. The air acts on the resin sand on the conveyor belt to cool it. Several exhaust ports are set at equal intervals to meet the requirements of uniform cooling and avoid the trouble of frequent material transfer. It can meet the needs of large-scale industrial production.

[0006] Furthermore, the leveling mechanism includes a threaded sleeve, a screw rod, a bearing, a scraper, and scraper teeth. A threaded sleeve is fixed to the bottom side of the horizontal end of the second mounting bracket. A screw rod is screwed to the bottom end of each threaded sleeve. A limiting bolt that mates with the threaded sleeve is screwed onto the screw rod. A scraper is rotatably connected to the bottom end of each screw rod via a bearing. Several scraper teeth are fixed at equal intervals on the bottom side of the scraper. During the conveying of resin sand, the scraper teeth are used to level the resin sand on the conveyor belt, making the resin sand evenly and flatly distributed on the conveyor belt, creating conditions for subsequent uniform cooling. The height of the scraper and scraper teeth can be adjusted by rotating the screw rod.

[0007] Furthermore, a wind speed sensor is fixed inside the air collection box, and electric valves are installed on the branch ducts respectively. The output of the wind speed sensor is electrically connected to the input of the controller, and the output of the controller is electrically connected to the input of the electric valves. The wind speed sensor monitors the wind speed inside the air collection box in real time and transmits the signal to the controller. The controller controls the opening degree of the electric valves on the branch ducts according to the received signal, thereby adjusting the air volume entering the air collection box and ensuring stable cooling wind speed.

[0008] Furthermore, each of the exhaust holes is fixed with a fan shroud. The fan shroud on the bottom side of the exhaust hole can make the exhaust airflow more evenly dispersed on the surface of the resin sand, further improving the uniformity of cooling.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. The resin sand can be conveyed by setting up a conveying mechanism. During the conveying process, an air supply mechanism delivers air to the air collection box and discharges it through the exhaust port. The air acts on the resin sand on the conveyor belt to cool it. Several exhaust ports are set at equal intervals to meet the requirements of uniform cooling, avoid the trouble of frequent material transfer, and meet the needs of large-scale industrial production.

[0010] 2. During the resin sand conveying process, scraper teeth are used to level the resin sand on the conveyor belt, ensuring that the resin sand is evenly and flatly distributed on the conveyor belt, creating conditions for subsequent uniform cooling. The height of the scraper and scraper teeth can be adjusted by rotating the screw. The wind speed sensor monitors the wind speed in the air collection box in real time and transmits the signal to the controller. The controller controls the opening of the electric valve on the branch air duct according to the received signal, thereby adjusting the air volume entering the air collection box and ensuring stable cooling wind speed. The wind hood on the bottom side of the exhaust port can more evenly disperse the exhaust airflow onto the surface of the resin sand, further improving the uniformity of cooling.
