Technical Field

[0001] The utility model relates to the technical field of part casting, and particularly relates to a casting cooling device for a turbine pump housing. Background Technique

[0002] In the casting process, liquid metal is poured into a mold cavity adapted to the shape and size of the part. After it cools and solidifies, a blank or part is formed, and this process is called casting. As an important mechanical component, the casting quality of the turbine pump housing directly affects the subsequent processing and the performance of the final product. After casting, the turbine pump housing needs to be rapidly cooled by spraying to shorten the production cycle and improve production efficiency. At the same time, rapid cooling also helps to reduce the residual stress and deformation inside the casting and improve the quality of the casting. However, during the spraying cooling process, a large amount of cooling water will be wasted, and the un-recovered cooling water may also cause environmental pollution, with poor environmental protection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 4 , in order to solve the problem that during spray cooling, a large amount of cooling water will be wasted, and the un-recovered cooling water may also cause environmental pollution and poor environmental protection, the following preferred technical solutions are provided:

[0022] A casting cooling device for a turbine pump housing includes a cooling box 2 provided at one end of a mold body 1. A receiving plate 3 is installed at the upper end of the cooling box 2. A spray head body 4 is installed on the upper wall of the receiving plate 3. A circulation pipe 5 is communicated with one side of the spray head body 4. A drawable filter assembly 6 is slidably arranged on the inner wall of the cooling box 2. A diversion inclined plate 7 is installed at the bottom of the cavity of the cooling box 2. The end of the circulation pipe 5 far from the spray head body 4 is fixedly connected to a circulation water pump 8. The circulation water pump 8 is installed at the bottom of the cavity of the cooling box 2. The diversion inclined plate 7 is inclined, and the lowest inclined part of the diversion inclined plate 7 is close to the circulation water pump 8.

[0023] The drawable filter assembly 6 includes a drawable frame 61 slidably matched with the inner wall of the cooling box 2. A first filter screen 62 and a second filter screen 63 are arranged on the inner wall of the drawable frame 61. Side connection plates are arranged at the side ends of the first filter screen 62 and the second filter screen 63. The first filter screen 62 is slidably connected to the inner wall of the drawable frame 61 through the side connection plate. The second filter screen 63 is fixedly connected to the inner wall of the drawable frame 61 through the side connection plate. The lower end of the side connection plate of the first filter screen 62 is slidably connected to a first shaft connecting rod 64. The other end of the first shaft connecting rod 64 is pivotally connected to a second shaft connecting rod 65. The other end of the second shaft connecting rod 65 is slidably connected to the side connection plate of the second filter screen 63. An elastic element 66 is fixedly connected between the included angles of the first shaft connecting rod 64 and the second shaft connecting rod 65. When the first filter screen 62 approaches the second filter screen 63, the elastic element 66 is in a compressed state.

[0024] Specifically, after the turbine pump housing is formed, it is withdrawn from the mold body 1. Subsequently, coolant is stored in the cavity of the cooling tank 2, and the circulating water pump 8 and the nozzle body 4 are driven. The circulating water pump 8 will introduce the coolant stored in the cavity of the cooling tank 2 into the circulating pipeline 5 and then spray it through the nozzle body 4, thereby rapidly cooling the turbine pump housing. The sprayed coolant will fall into the pull-out filter assembly 6, be filtered by the pull-out filter assembly 6, and then fall into the cavity of the cooling tank 2 for collection, achieving the purpose of recycling, with good environmental protection. This solves the problem that during spray cooling, a large amount of cooling water is wasted, and the un-recovered cooling water may also pollute the environment, resulting in poor environmental protection.

[0025] Moreover, through the guide inclined plate 7, the suction efficiency of the circulating water pump 8 can be guaranteed. When the coolant falls into the pull-out filter assembly 6, the downward gravity will drive the first filter screen 62 to move downward through the side connection plate, causing the first filter screen 62 to approach the second filter screen 63, thereby driving the angle between the first shaft connecting rod 64 and the second shaft connecting rod 65 to become smaller, squeezing the elastic element 66. At this time, through the reaction force of the elastic element 66, the first shaft connecting rod 64 and the second shaft connecting rod 65 will be quickly reset, causing the first filter screen 62 to move away from the second filter screen 63. Repeating this process, the first filter screen 62 is driven to vibrate continuously, thereby improving the efficiency of filtering the coolant.

[0026] In summary: Coolant is stored in the cavity of the cooling tank 2, and the circulating water pump 8 and the nozzle body 4 are driven. The circulating water pump 8 will introduce the coolant stored in the cavity of the cooling tank 2 into the circulating pipeline 5 and then spray it through the nozzle body 4, thereby rapidly cooling the turbine pump housing. The sprayed coolant will fall into the pull-out filter assembly 6, be filtered by the pull-out filter assembly 6. When the coolant falls into the pull-out filter assembly 6, the downward gravity will drive the first filter screen 62 to move downward through the side connection plate, causing the first filter screen 62 to approach the second filter screen 63, thereby driving the angle between the first shaft connecting rod 64 and the second shaft connecting rod 65 to become smaller, squeezing the elastic element 66. At this time, through the reaction force of the elastic element 66, the first shaft connecting rod 64 and the second shaft connecting rod 65 will be quickly reset, causing the first filter screen 62 to move away from the second filter screen 63. Repeating this process, the first filter screen 62 is driven to vibrate continuously, thereby improving the efficiency of filtering the coolant. After filtering, it then falls into the cavity of the cooling tank 2 for collection, achieving the purpose of recycling.
