Description

Technical Field

[0001] The utility model relates to the technical field of boiling cooling beds, and particularly relates to a boiling cooling bed. Background Art

[0002] A boiling cooling bed is an efficient heat exchange device, which is widely used in the cooling of molding sand and the separation of fine powder in the casting industry. Its working principle is to utilize a large amount of heat released during the liquid boiling process and transfer the heat to the fluid rapidly through the natural circulation method to achieve the purpose of rapid cooling.

[0003] When the existing boiling cooling bed cools powder materials, due to the lack of full-process sealing treatment in the heat exchange process, there is a problem of dust spillage. This not only increases the risk of workers suffering from occupational diseases but also is not conducive to environmental protection. In addition, such equipment is not suitable for the treatment of flammable and explosive powder materials. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a boiling cooling bed for solving the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A feed inlet is provided on the left side of the lower box body, and a discharge outlet is provided on the right side of the lower box body. A plurality of parallel air-cooling pipes are provided at the bottom of the inner cavity of the lower box body, and the air-cooling pipes are connected to a fan through an air supply pipeline. A first air guide plate and a second air guide plate are alternately arranged between the air-cooling pipes. Both the first air guide plate and the second air guide plate are vertically arranged and the first air guide plate is higher than the second air guide plate. A bent section is provided at the upper end of the first air guide plate, and the bent section is bent towards the discharge outlet side. A serpentine water-cooling heat exchange pipe is provided at the right side of the bottom of the lower box body, and the water-cooling heat exchange pipe is arranged between the adjacent first air guide plate and the second air guide plate, and flowing cooling water is introduced into the water-cooling heat exchange pipe.

[0007] Further, the air supply pipeline includes a main air supply pipe, a first connecting pipe, a branch air supply pipe and a second connecting pipe which are connected in sequence. The main air supply pipe is connected with a plurality of first connecting pipes, the lower end of each first connecting pipe is connected with a branch air supply pipe, a plurality of second connecting pipes are connected to the lower side of the branch air supply pipe, and each second connecting pipe is connected with an air-cooling pipe.

[0008] Further, a valve is provided on the first connecting pipe.

[0009] Further, a smoke exhaust pipe and a return material pipe are provided on the upper cover.

[0010] Further, lifting lugs are provided on the upper side of the lower box body.

[0011] Further, a plurality of upward jet ports are opened on the air-cooling pipes.

[0012] The utility model further includes other components that can enable the boiling cooling bed to be used normally, and these devices or components all adopt conventional technical means in the art. In addition, the devices and components not defined in the utility model all adopt conventional technical means in the art, such as valves in this application. In the specific implementation process, appropriate models of devices or components can be selected according to the specific working scenario.

[0013] The working principle of the utility model is as follows: The lower box body and the upper cover are sealed and buckled, so that a sealed space is formed inside the boiling cooling bed, ensuring that the whole heat exchange process is in a sealed state and avoiding dust overflow. The water-cooled heat exchange pipe is arranged on the right side of the lower box body. At the same time, the bent section at the upper end of the first air guide plate is bent towards the discharge port side, playing a role in guiding the wind direction, reducing the phenomenon of turbulent flow and eddy current, thereby improving the utilization efficiency of the wind force and also helping the powder materials to move to the discharge port. When it is necessary to cool flammable and explosive powder materials, inert gas is introduced from the air supply pipeline for targeted cooling to ensure operation safety.

[0014] Compared with the prior art, the utility model has the following beneficial effects: 1. The whole heat exchange process is treated in a sealed manner, avoiding dust overflow, protecting the health of personnel and the environment. 2. It has a wide range of applicability and can cool flammable and explosive powder materials. Brief Description of the Drawings
