Description

Technical Field

[0001] This utility model belongs to the technical field of spherical product processing equipment, specifically relating to an integrated cooling and drying device for spherical products. Background Technology

[0002] In the production and processing of spherical products (such as grinding balls, freeze-dried microspheres, and plastic balls), cooling and drying are two key post-processing steps that directly affect the dimensional accuracy, surface quality, and performance of the spherical products. Currently, existing technologies mostly employ separate equipment for cooling and drying spherical products. That is, the high-temperature sphericals that have just been processed are first cooled by a cooling device, and then transferred to a drying device for drying.

[0003] This split-processing method has many drawbacks: First, the equipment occupies a large area and requires separate cooling and drying equipment, which increases the company's infrastructure and equipment investment costs; second, after the spherical products are cooled by cold air, they also need to be dried by hot air blowers and other equipment, which results in excessive energy consumption; third, some existing equipment has a long material cooling time, which can easily lead to clumping, incomplete drying, or insufficient cooling, making it difficult to meet the needs of large-scale production. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cooling and drying integrated device for spherical products includes a first feed pipe, a second feed pipe, a first fan, and a second fan. The first feed pipe is connected to a cooler. The cooler contains a conical cooling tower and multiple fixed columns. The conical cooling tower consists of multiple baffles, a cone, and a base. The cone has multiple ventilation openings, and the base has a central hole and multiple edge holes. The central hole is connected to the first fan pipe, and the multiple edge holes are connected to the multiple fixed columns one by one. The upper end of the cooler is connected to the second fan pipe, and the second fan pipe is connected to the second fan. The other end of the second fan is provided with a diversion pipe. The upper end of the diversion pipe is connected to an upper drying chamber, and the lower end of the diversion pipe is connected to a lower drying chamber. The upper drying chamber is connected to the second feed pipe, and the lower drying chamber is connected to a second discharge chamber.

[0006] Furthermore: the first fan pipe passes through the first discharge hopper and the central hole, and is connected to the interior of the conical cooling tower.

[0007] Furthermore: the upper end of the conical cooling tower is provided with a through hole, and the multiple baffles divide the conical cooling tower into multiple layers, with multiple ventilation openings distributed in each layer.

[0008] Furthermore: a first bracket is provided at the lower end of the cooler, a first fan is provided on one side of the first bracket, and a second bracket is provided on the other side.

[0009] Furthermore: the mounting base of the second fan is mounted on the second bracket.

[0010] Furthermore: a lower drying chamber and a second discharge chamber are installed on the third support. The lower drying chamber is internally connected to the upper drying chamber, and the upper drying chamber is internally connected to the second feed pipe.

[0011] Furthermore, both the first and second fans are centrifugal fans.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model realizes the integrated processing of cooling and drying of spherical products, which greatly improves production efficiency, while reducing the equipment footprint and lowering the company's infrastructure and equipment investment costs.

[0014] 2. The conical cooling tower used is made of 12mm thick Q235 steel plate and is welded together from multiple baffles, cones and base. Each baffle has evenly distributed and staggered air outlets at the bottom. The air inlet of the base is connected to the air outlet of a centrifugal fan. This makes the sphere dissipate heat faster and improves the cooling efficiency by 30%. The cooled hot air is used for drying, saving energy. The filter device on the second fan pipe can filter dust and impurities in the hot air to avoid contaminating the sphere and ensure product quality. Attached Figure Description

[0030] During production, the plate-shaped corundum spheres, after high-temperature sintering in a vertical kiln, reach a temperature of 300°C. This temperature affects the normal operation of the equipment in the process. Therefore, an integrated cooling and drying device was designed. During operation, the 300°C plate-shaped corundum spheres enter the cooler 2 through the first feed pipe 1, and are evenly covered on the conical cooling tower 9. They continuously enter and exit from top to bottom. At the same time, the first fan 11 sends air at ambient temperature into the interior of the conical cooling tower and blows it out through the air outlet on the cooling tower to cool the product. The temperature of the cooled product is 60°C, which meets the production conditions of subsequent processes. The hot air coming out of the cooler outlet reaches a temperature of 150°C. This hot air is sent to the drying chamber of the semi-finished product through the second fan 3, achieving a good drying effect and saving energy.
