Description

Technical Field

[0001] The utility model relates to the technical field of cooling boiling furnaces, in particular to a gypsum powder cooling boiling furnace. Background Art

[0002] Fluidized bed furnace is a coal-fired boiler, one of the new combustion technologies developed in recent years. Modern fluidized bed furnace is a thermal equipment using "aggregate fluidized bed" technology. When the fluid flows from bottom to top through the static granular material layer, if the flow rate exceeds a certain limit, the bulk material layer begins to expand, creep and become fluid, turning into a pseudo-fluid state. This process is called fluidization of the bulk material layer. The granular material after fluidization flips up and down, which is similar to the boiling of the fluid, so it is also called a boiling layer. The thermal equipment that uses this method to process materials is called a fluidized bed furnace.

[0003] In actual use, the existing fluidized bed furnace uses a rotating mechanism to boil materials. Once damaged, it needs to be disassembled and repaired, which is very troublesome. Therefore, a gypsum powder cooling fluidized bed furnace is proposed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a gypsum powder cooling boiling furnace to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] As an optional solution of the gypsum powder cooling boiling furnace of the utility model, the gypsum powder cooling boiling furnace comprises a furnace body and a bracket.

[0007] The top of the bracket is fixedly connected to the furnace body, and the outer side of the furnace body is fixedly connected to the air connection pipe.

[0008] A fan is installed on the outside of the air connection pipe;

[0009] The interior of the furnace body is also fixedly connected with evenly distributed hollow steel pipes.

[0010] As an optional solution of the gypsum powder cooling boiling furnace of the utility model, a connecting pipe is fixedly connected to the lower side of the furnace body, a fan is externally connected to the outer side of the connecting pipe, and an evenly distributed air distribution plate is installed inside the bottom of the furnace body.

[0011] In the actual use of the existing boiling furnace, when the boiling furnace is boiling, it adopts a rotating mechanism set in the furnace for material boiling work. Once it is damaged, it needs to be disassembled and repaired, which is very troublesome. When the device is used, an external power supply is connected, and evenly distributed air distribution plates are set inside the furnace body. Cold air is blown into the furnace body through a fan (not shown in the figure), and the powder in the furnace body is blown to a boiling state. At a certain temperature, the powder is cooled by the forcing and becomes lighter, and then automatically flows to the discharge port. The quality of the gypsum powder produced in this way is stable, and the crystal water content and the initial and final setting time are relatively easy to control. In addition, the structure of the device is simple and not easy to be damaged. Since the material is fluidized, the furnace does not need to have rotating parts, and the structure of the furnace is much simpler. It is not only easy to manufacture, but also requires almost no maintenance after production. Since cold air is used, the furnace is not in danger of being burned under any circumstances, and the service life of the equipment is particularly long. The cold air is driven by the fan (not shown in the figure) to pass through the hollow steel pipe to exchange heat with the material and release heat to the cold air, so as to achieve the purpose of rapid cooling.

[0012] As an optional solution of the gypsum powder cooling boiling furnace of the utility model, a hollow frame is installed on a side of the furnace body opposite to the air pipe, and the hollow frame covers one end of the hollow steel pipe.

[0013] When the fan blows external air into the hollow steel pipe, it flows to the inside of the hollow frame on the other side. Since the hollow frame is hollow, the air can be discharged through the hollow steel pipe on the other side to achieve circulation.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model is provided with evenly distributed air distribution plates inside the furnace body, and cold air is blown into the furnace body through the fan to blow the powder inside the furnace body to a boiling state. At a certain temperature, the powder is cooled by the fortunator, and after the weight becomes lighter, it automatically flows to the discharge port. The quality of the gypsum powder produced in this way is stable, and the crystal water content and the initial and final setting time are relatively easy to control. In addition, the device has a simple structure and is not easy to damage. Since the material has been fluidized, the furnace does not need to have rotating parts, and the structure of the furnace is much simpler. It is not only easy to manufacture, but also requires almost no maintenance after it is put into production. Since cold air is used, the furnace is not in danger of being burned under any circumstances, and the service life of the equipment is also particularly long.

[0016] And the fan will drive the cold air to pass through the pipe, exchange heat with the material, and release the heat to the cold air, so as to achieve the purpose of rapid cooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example 1

[0023] See also Figure 1 , Figure 2 and Figure 3 , the utility model provides a technical solution:

[0024] The gypsum powder cooling boiling furnace comprises a furnace body 1 and a support 5.

[0025] The top of the bracket 5 is fixedly connected to the furnace body 1, and the outer side of the furnace body 1 is fixedly connected to the air connection pipe 2.

[0026] A fan is installed on the outside of the air connection pipe 2;

[0027] The interior of the furnace body 1 is also fixedly connected with uniformly distributed hollow steel pipes 3 .

[0028] A connecting pipe 4 is fixedly connected to the lower side of the furnace body 1 , and a fan is externally connected to the outer side of the connecting pipe 4 . An evenly distributed air distribution plate 6 is installed inside the bottom of the furnace body 1 .

[0029] In the actual use of the existing boiling furnace, when the boiling furnace is boiling, it adopts a rotating mechanism set in the furnace for boiling the material. Once it is damaged, it needs to be disassembled for maintenance, which is very troublesome. When the device is used, an external power supply is connected, and evenly distributed air distribution plates 6 are set inside the furnace body 1. Cold air is blown into the furnace body 1 through a fan (not shown in the figure), and the powder in the furnace body 1 is blown to a boiling state. At a certain temperature, the powder is cooled by the forcing and becomes lighter, and then automatically flows to the discharge port. In this way, the quality of the gypsum powder produced is stable and the structure is good. The crystal water content and the initial and final setting time are relatively easy to control, and the device has a simple structure and is not easy to damage. Since the material is fluidized, the furnace does not need to have rotating parts, and the structure of the furnace is much simpler. It is not only easy to manufacture, but also requires almost no maintenance after production. Since cold air is used, the furnace is not in danger of being burned under any circumstances, and the service life of the equipment is particularly long. The cold air is driven by the fan (not shown in the figure) to pass through the hollow steel pipe 3, exchange heat with the material, and release heat to the cold air, so as to achieve the purpose of rapid cooling.

[0032] When the fan blows external air into the hollow steel pipe 3, it flows to the inside of the hollow frame 7 on the other side. Since the hollow frame 7 is hollow, the air can be discharged through the hollow steel pipe 3 on the other side to achieve a circulating flow.
