However, in the ball blowing process of capacitive zirconia, the high-temperature raw material solution will produce heat radiation, causing the iron plate to deform, and the tuyere to deform or even be damaged, thereby affecting the product quality and reducing the production efficiency. UTILITY MODEL CONTENTS

[0003] The technical problem to be solved by the utility model is that in the ball blowing process of capacitive zirconia, the high-temperature raw material solution will produce heat radiation, causing the iron plate to deform, and the tuyere to deform or even be damaged, thereby affecting the product quality and reducing the production efficiency. Therefore, the utility model provides a forming device and an electric arc furnace.

[0004] The first aspect of the utility model provides a forming device.

[0005] The second aspect of the utility model provides an electric arc furnace.

[0006] Therefore, the first aspect of the utility model provides a forming device, which comprises a seat body, a first shell and a second shell. A cavity is formed in the first shell, and a first inlet and a first outlet are formed in the side wall of the first shell and communicate with the cavity. The second shell is sealingly connected to the side wall of the first shell, and a flow channel is formed between the second shell and the first shell. At least part of the side wall of the first shell near the first outlet can exchange heat with the heat exchange medium in the flow channel.

[0007] In the technical solution, the forming device comprises a seat body, a first shell and a second shell, the first shell is mounted on the seat body, the seat body can reduce the shaking of the first shell during operation, so that the forming device can output more stably. A cavity is formed in the first shell, and a first inlet and a first outlet are respectively formed in the side wall of the first shell and communicate with the cavity. The gas flows into the first shell from the first inlet, enters the cavity first, and then flows from the cavity to the first outlet and flows out from the first outlet. The first outlet can pressurize the gas in the cavity, so that the gas forms a gas flow with a certain pressure and is blown towards the raw material solution to be processed, so that the high-temperature raw material solution is shaped into a zirconia ball by blowing high-pressure gas. The second shell is sealingly connected to the side wall of the first shell, and the second shell also has a cavity. Therefore, when the second shell is sealingly connected to the first shell, a sealed flow channel is formed between the inner wall of the second shell and the side wall of the first shell, and all the side walls of the first shell near the first outlet can exchange heat with the heat exchange medium in the flow channel through heat conduction or heat coupling, so as to take away the heat of the side wall of the first outlet and cool it down.

[0008] Further, the first inlet and the first outlet can be arranged on the same side wall of the first shell, or can be arranged on different side walls of the first shell.

[0009] Further, the second shell can be a semi-open structure, and an opening is formed in the side of the second shell close to the first shell. The second shell is sealingly connected to the side wall of the first shell through the opening end face.

[0010] By sealingly connecting the first shell and the second shell, a flow channel for circulating the heat exchange medium is formed, and the heat exchange medium directly or indirectly contacts the side wall of the first outlet, so that heat exchange is formed between the side wall of the first outlet and the heat exchange medium in the flow channel, so as to cool down the side wall of the first outlet. The risk of deformation of the side wall of the first outlet due to heat radiation is reduced, and the production efficiency is improved.

The first sealing end is located on the side wall of the second shell facing the raw material solution to be processed, and an opening is formed at the first sealing end, which is in communication with the first outlet. The inner periphery of the opening is matched with the outer periphery of the end of the first outlet. When the second shell is connected to the first shell in a sealed manner, the end of the first outlet is located in the opening, and the inner periphery of the opening is connected to the outer periphery of the end of the first outlet in a sealed manner. The heat exchange medium in the flow channel flows between the first sealing end and the second sealing end, and exchanges heat with all the side walls close to the first outlet.

[0013] Further, the first shell and the second shell can be connected in a sealed manner by a sealing rubber member, or can be connected in a sealed manner by welding or other processes.

[0014] Further, the heat source of all the side walls close to the first outlet includes, but is not limited to, the heat generated by the side wall where the first outlet is located due to heat radiation, and the heat transferred from other side walls of the first shell to the side wall where the first outlet is located.

[0015] By connecting the first sealing end and the second sealing end of the second shell to the side wall where the first outlet of the first shell is located and the side wall of the first shell away from the first outlet respectively in a sealed manner, the end of the first outlet can be located in the opening to blow high-pressure gas to the raw material solution normally, and the flow channel can surround the outer periphery of all the side walls close to the first outlet, so that the heat exchange medium can exchange heat with all the side walls close to the first outlet sufficiently, thereby realizing the cyclic cooling of all the side walls of the first shell close to the first outlet.

[0016] In an implementation form of the technical solution, optionally, the first shell includes a first side wall, a second side wall, and a third side wall connected between the first side wall and the second side wall. The first outlet is located on the third side wall. The first side wall and the other side wall of the second shell form a first part of the flow channel, and the second side wall and the other side wall of the second shell form a second part of the flow channel. The second shell is provided with a second inlet in communication with the first part and a second outlet in communication with the second part. A first partition is arranged between the second shell and the first shell, and the first partition is used to separate the first part and the second part, so that the heat exchange medium can enter the first part through the second inlet, flow through the second part, and be discharged through the second outlet.

[0017] The first shell comprises a first side wall, a second side wall and a third side wall, the third side wall is located between the first side wall and the second side wall and is connected to the first side wall and the second side wall respectively. The third side wall faces the raw material solution in pouring, and the first outlet is arranged on the third side wall and can blow high-pressure gas to the raw material solution. The first side wall of the first shell and one or more side walls of the second shell form a first part of the flow channel, the second side wall of the first shell and one or more side walls of the second shell form a second part of the flow channel, and the first part and the second part of the flow channel are in communication with each other. The second shell is provided with a second inlet in communication with the first part and a second outlet in communication with the second part, and a first partition is arranged between the second shell and the first shell, so that the flow channel is divided into the first part and the second part. When the forming device is running, the heat exchange medium flows into the flow channel from the second inlet, flows through the first part first, then flows to the second part, and finally flows out of the flow channel from the second outlet, so as to complete a heat exchange cycle.

[0018] Further, the first partition is one, which can be fixedly connected to the inner wall of the first shell or the second shell, or can be detachably connected to the inner wall of the first shell or the second shell, and the first partition is located between the second inlet and the second outlet. When the forming device is running, the first partition can abut against the side wall of the first outlet close to the second inlet, or there can be a gap between the first partition and the first outlet.

[0019] By arranging the first partition, the flow channel is divided into two parts, the second inlet and the second outlet are respectively connected to the first part and the second part of the flow channel, the length of the flow channel is increased, and the heat exchange medium must flow through the first part and the second part before leaving the flow channel, so that the heat exchange medium has sufficient residence time to fully exchange heat with the side walls close to the first outlet, thereby taking away the heat of the side walls close to the first outlet.

Since the second partition is arranged, a plurality of sub-cavities are formed, and a plurality of first outlets are arranged. The number of the first outlets is equal to the number of the sub-cavities, and each first outlet corresponds to and communicates with a sub-cavity. Since the second partition is arranged in the cavity, the airflow in each sub-cavity is compressed due to the smaller space, and thus the airflow flowing out of each first outlet corresponding to the sub-cavity has greater jet pressure compared with the case where the second partition is not arranged.

[0022] Further, the plurality of first outlets are parallel to each other.

[0023] Further, the flow cross sections of the plurality of first outlets are the same.

The number of the first outlets is increased, and the gas outlet pressure of each first outlet is also increased. The high-pressure gas after pressure boosting can not only increase the distance between the raw material solution and the first outlet and reduce the heat radiation effect of the high-temperature raw material solution on the sidewall where the first outlet is located, but also can make the raw material solution in pouring quickly form zirconia balls, thereby reducing the risk of deformation and damage of the sidewall where the first outlet is located and improving the production efficiency of the zirconia balls.

[0060] Based on this technical problem, the following embodiments are proposed.

[0061] Embodiment one

[0062] A forming device, such as Figures 1 to 6As shown, it includes: a base 1; a first housing 2, in which a cavity 201 is formed, and a first inlet 202 and a first outlet 203 communicating with the cavity 201 are provided on the side wall of the first housing 2; a second housing 3, which is sealed to the side wall of the first housing 2, and a flow channel is formed between the second housing 3 and the first housing 2; at least a portion of the side wall of the first housing 2 near the first outlet 203 is capable of heat exchange with the heat exchange medium in the flow channel.

The first housing 2 is mounted on the base 1, and the base 1 can reduce the vibration of the first housing 2 during operation, allowing the molding device to output more smoothly. A cavity 201 is formed inside the first housing 2, and a first inlet 202 and a first outlet 203 communicating with the cavity 201 are respectively opened on the side wall of the first housing 2. Gas flows into the first housing 2 from the first inlet 202, first enters the cavity 201, and then flows from the cavity 201 to the first outlet 203 and flows out from the first outlet 203. The first outlet 203 can pressurize the gas in the cavity 201, making it form an airflow with a certain pressure and blowing it toward the raw material solution to be processed, thereby molding it into zirconia spheres by blowing high-pressure gas into the high-temperature raw material solution. The second housing 3 is sealed to the side wall of the first housing 2. The interior of the second housing 3 also has a cavity. Therefore, when the second housing 3 is sealed to the first housing 2, a sealed flow channel is formed between the inner wall of the second housing 3 and the side wall of the first housing 2. All the side walls of the first housing 2 near the first outlet 203 can exchange heat with the heat exchange medium in the flow channel through heat conduction or heat coupling, thereby carrying away the heat from the side wall at the first outlet 203 and cooling it down.

When the second shell 3 is sealingly connected with the first shell 2, the end of the first outlet 203 is located in the opening, and the inner periphery of the opening is sealingly connected with the outer periphery of the end of the first outlet 203. The heat exchange medium in the flow channel flows between the first sealing end 301 and the second sealing end 302, and exchanges heat with all the side walls close to the first outlet 203.

[0075] By setting the first partition 5, the flow channel is divided into two parts, and the second inlet 304 and the second outlet 305 are respectively connected with the first part 401 and the second part 402 of the flow channel, thereby increasing the length of the flow channel, so that the heat exchange medium must flow through the first part 401 and the second part 402 before leaving the flow channel, thereby making the heat exchange medium have sufficient residence time to fully exchange heat with the side walls near the first outlet 203, thereby taking away the heat of the side walls of the first outlet 203.

The number of the first outlets 203 is equal to the number of the sub-cavities 201, and each first outlet 203 corresponds to and is in communication with a sub-cavity 201. Since the second partition 6 is arranged in the cavity 201, the airflow in each sub-cavity 201 is compressed due to the smaller space, so the airflow flowing out of each first outlet 203 corresponding to the sub-cavity 201 has greater jet pressure compared with when the second partition 6 is not added.
