Description

Technical Field

[0001] The utility model relates to the technical field of steel shot processing, and particularly relates to a steel shot cooling device for a casting and molding device. Background Technique

[0002] Steel shot is a commonly used metal workpiece processing material. The steel shot has a dense structure and uniform particle size. After being shaped by a casting machine, the steel shot needs to be cooled for subsequent screening and packaging work. Most of the existing steel shot cooling methods adopt air cooling or water cooling methods.

[0003] In the prior art, a Chinese patent with the publication number CN214470126U discloses a steel shot cooling device, which adopts the scheme of "a feeding box is fixed at the upper part of one end of the first cooling tank, and a discharge port is arranged at the other end. A second cooling tank is arranged below the discharge port of the first cooling tank. A discharge port is arranged at the end of the second cooling tank. A storage tank is arranged below the discharge port of the second cooling tank. The cooling tank is a double-layer rectangular tank structure. The bottom surface of the upper tank body is the steel shot cooling vibration surface. Baffles are installed on both sides of the upper tank body. The lower tank body is an air-cooled box body. Two blowers are installed at intervals on the side surface of the air-cooled box body. An air discharge port is arranged at the bottom of the air-cooled box body. A motor for controlling the vibration of the vibration surface is installed at the bottom of the cooling tank. The cooling tank is supported by a bracket, and an elastic member is installed at the connection part between the bracket and the cooling tank". The advantage of this scheme is that the two groups of cooling tanks are cooled simultaneously by four blowers, which improves the production efficiency and greatly reduces the cooling time.

[0004] However, the above scheme still has some deficiencies. For example, the above scheme realizes the cooling of steel shot by setting multiple cooling tanks and blowers. The setting of multiple blowers greatly increases the R & D cost and subsequent power consumption of the device. At the same time, the design of the cooling tank will cause several steel shots to pile up together, resulting in the situation of heat superposition, which is not conducive to the subsequent cooling of the cooling device, and thus reduces the cooling effect and efficiency of the cooling device. In view of this, the utility model provides a steel shot cooling device for a casting and molding device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a steel shot cooling device for a casting and molding device to solve the problems put forward in the above background technique.

A sealing cover 5 is fixedly installed on the surface of the cooling cylinder 1. A blower 6 is fixedly installed on the right surface of the sealing cover 5. The air outlet end of the blower 6 extends into the interior of the sealing cover 5.

[0025] The number of the ventilation holes 7 is several. Every twelve of the several ventilation holes 7 are divided into several groups. The several groups of ventilation holes 7 are equidistantly arranged on the inner wall of the cooling cylinder 1. Semiconductor refrigerators 8 are embedded on both side surfaces of the cooling cylinder 1. The side of the semiconductor refrigerator 8 located inside the sealing cover 5 is the refrigerating end, and the side of the semiconductor refrigerator 8 away from the sealing cover 5 is the heat dissipation end. Through the setting of the semiconductor refrigerators 8, the air flow blown out by the blower 6 can be refrigerated, improving the cooling effect of the device.

[0026] An inlet 9 and an outlet 10 are respectively arranged at the upper and lower ends of the cooling cylinder 1. A cleaning mechanism is arranged at the lower end of the cooling cylinder 1. The cleaning mechanism includes an installation cylinder 11 fixedly installed at the lower end of the cooling cylinder 1. A cleaning rotating cylinder 12 is arranged inside the installation cylinder 11. First bristles 13 are arranged on the inner wall of the cleaning rotating cylinder 12. A transmission opening is provided at the lower end of the cooling cylinder 1. The lower end of the transmission rod 3 extends into the interior of the installation cylinder 11 through the transmission opening and is provided with second bristles 14.

[0027] The number of both the first bristles 13 and the second bristles 14 is several. The several first bristles 13 and second bristles 14 are respectively arranged in a circumferential array on the inner wall of the cleaning rotating cylinder 12 and the surface of the lower end of the transmission rod 3. Through the setting of the first bristles 13 and the second bristles 14, the steel shot discharged from the outlet 10 after cooling can be swept and brushed.

[0028] The surface of the cleaning rotating cylinder 12 is provided with an annular slider 15, and the inner wall of the mounting cylinder 11 is provided with an annular chute adapted to the annular slider 15. The cleaning rotating cylinder 12 is rotationally connected to the inside of the mounting cylinder 11 through the annular slider 15 and the annular chute.

At this time, under the operation of the driving motor 2, the transmission rod 3 rotates, and the rotation of the transmission rod 3 drives the auger conveying blades 4 to rotate. The rotation of the auger conveying blades 4 pushes the steel shots thereon downward until they are discharged from the discharge port 10. During this period, under the operation of the blower 6, air flow is blown into the sealing cover 5 and then into the cooling cylinder 1 through the ventilation holes 7 to cool the steel shots inside. Under the action of the semiconductor cooler 8, the temperature of the air flow can be reduced to form cold air, further improving the cooling effect of the cooling device. While driving the auger conveying blades 4 to rotate, the transmission rod 3 also drives the driving gear 17 thereon and the second brush bristles 14 to rotate together. The rotation of the driving gear 17 drives the transmission gear 16 to rotate synchronously, and the rotation of the transmission gear 16 drives the cleaning rotating cylinder 12 to rotate together through the gear groove 18.
