Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to an external cooling circulating heat exchange device for an electrolytic manganese cell. Background Technology

[0002] Traditional cooling devices for electrolytic manganese cells, such as serpentine coil cooling systems made of stainless steel tubes and plastic corrugated tube heat exchangers, have certain limitations. While stainless steel tube cooling systems offer good heat exchange at the inlet, the heat exchange effect gradually deteriorates as the temperature inside the tube increases and the temperature difference between the inside and outside decreases. Furthermore, they consume a large amount of water and have high energy consumption. In addition, because stainless steel is conductive, it easily carries away a significant amount of electrical energy, increasing the electricity consumption per ton of manganese produced.

[0003] Currently, existing heat recovery devices have low heat exchange efficiency and cannot effectively recover the heat generated by large-scale production equipment. To address this, we provide a material regenerator consisting of two heat exchangers connected in parallel. This improves the heat exchange rate, meets production needs, saves space, and significantly enhances heat exchange efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an external cooling circulating heat exchange device for electrolytic manganese tanks, solving the technical problem that existing heat recovery devices have low heat exchange efficiency and cannot effectively recover the heat generated by large-scale production equipment.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An external cooling circulating heat exchange device for an electrolytic manganese cell includes a heat exchanger 1. Two bottom support legs are fixedly connected to the bottom of the heat exchanger 1 for supporting the device. A heat exchanger 2 is arranged directly above the heat exchanger 1. A connecting column is fixedly connected between the heat exchanger 1 and the heat exchanger 2. A water outlet is provided on one side of the bottom of the heat exchanger 1, and a water inlet is provided on one side of the top of the heat exchanger 2. A sealing layer is provided inside the heat exchanger 1 and the heat exchanger 2 near the water outlet and the water inlet, and multiple heat exchange pipes are embedded inside the sealing layer.

[0009] Preferably, the heat exchanger one and the heat exchanger two are fitted with a feeding connecting hopper on one side of the sealing layer. One end of the feeding connecting hopper is provided with a connecting flange and a positioning hole. The surfaces of the heat exchanger one and the heat exchanger two are provided with fixing parts for fixing the feeding connecting hopper.

[0010] Preferably, the fixing component includes a mounting block, a positioning rod, a connecting rod, and a restoring spring.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting up a feeding hopper, connecting flange, fixing parts, positioning holes and sealing gaskets, connects the feeding hopper to the outlet of the electrolytic manganese cell through the connecting flange. The other end of the feeding hopper is sleeved on the outside of one end of heat exchanger one and heat exchanger two. During the sleeved process, the positioning rod is pulled upward. The positioning rod compresses the return spring through the connecting rod, so that the feeding hopper can be completely sleeved on the outside of heat exchanger one and heat exchanger two. When the positioning rod is released, the positioning rod enters the positioning hole under the force of the return spring, thus fixing the feeding hopper. The sealing gasket on the inside of the feeding hopper can prevent material from overflowing from between the feeding hopper and heat exchanger one and heat exchanger two.

[0018] 2. This utility model, by setting up an inlet, an outlet, a sealing layer, a heat exchange pipe, a deflector baffle, and a connecting pipe, allows the material inside the electrolytic manganese cell to be fed into the feed hopper. The material enters the heat exchange pipe, and then cooling water is introduced into the first heat exchanger through the inlet. The cooling water passes through multiple deflector baffles and finally enters the second heat exchanger through the connecting pipe. After passing through multiple deflector baffles, it is discharged from the outlet. Under the action of the deflector baffles, the time inside the first and second heat exchangers can be extended, which greatly improves the heat exchange efficiency. Attached Figure Description

[0024] Example 1

[0025] The technical solution in this application embodiment effectively solves the problem that existing heat recovery devices have low heat exchange efficiency and cannot effectively recover heat generated by large-scale production equipment. The overall idea is as follows:

[0026] like Figures 1 to 3 To address the problems existing in the prior art, this utility model provides an external cooling circulating heat exchange device for an electrolytic manganese cell, including a heat exchanger 1. Two bottom support legs 11 are fixedly connected to the bottom of the heat exchanger 1 for supporting the device. A heat exchanger 2 is positioned directly above the heat exchanger 1. A connecting column 12 is fixedly connected between the heat exchanger 1 and the heat exchanger 2. A water outlet 202 is provided on one side of the bottom of the heat exchanger 1, and a water inlet 201 is provided on one side of the top of the heat exchanger 2. Both heat exchanger 1 and heat exchanger 2 have a sealing layer 301 inside near the outlet 202 and inlet 201. Multiple heat exchange pipes 302 are embedded inside the sealing layer 301. Multiple deflection baffles 303 are fixedly fitted on the outside of the heat exchange pipes 302. The multiple deflection baffles 303 are arranged regularly inside the heat exchanger 1 and heat exchanger 2. A connecting pipe 304 is connected to the end of heat exchanger 1 and heat exchanger 2 away from the inlet 201 and outlet 202.

[0027] Specifically, the material inside the electrolytic manganese cell is fed into the feed hopper 4 and enters the heat exchange pipe 302. Cooling water is then fed into the heat exchanger 1 through the inlet 201. The cooling water passes through multiple baffles 303 and finally enters the heat exchanger 2 through the connecting pipe 304. After passing through multiple baffles 303, it is discharged from the outlet 202. Under the action of the baffles 303, the time inside the heat exchanger 1 and the heat exchanger 2 can be extended, which greatly improves the heat exchange efficiency.

[0028] Example 2

[0029] like Figures 1 to 3 A feeding connecting hopper 4 is sleeved on one side of the sealing layer 301 for heat exchanger 1 and heat exchanger 2. A connecting flange 41 is provided at one end of the feeding connecting hopper 4, and a positioning hole 43 is opened at one end of the feeding connecting hopper 4. Fixing members 42 for fixing the feeding connecting hopper 4 are provided on the surface of heat exchanger 1 and heat exchanger 2. The fixing members 42 include a mounting block 421, a positioning rod 422, a connecting rod 423 and a restoring spring 424. The mounting block 421 is fixedly connected to the top side of heat exchanger 1 and heat exchanger 2. A positioning rod 422 is inserted into the top of the mounting block 421. A connecting rod 423 is fixedly connected to one side of the positioning rod 422. A restoring spring 424 is fixedly connected between one side of the connecting rod 423 and the mounting block 421. A sealing gasket 44 is fixedly connected to the inner side of the feeding connecting hopper 4.

[0030] By adopting the above technical solution, the feeding hopper 4 is connected to the outlet of the electrolytic manganese cell via the connecting flange 41. The other end of the feeding hopper 4 is sleeved outside one end of heat exchanger 1 and heat exchanger 2. During the sleeved process, the positioning rod 422 is pulled upward. The positioning rod 422 compresses the restoring spring 424 through the connecting rod 423, so that the feeding hopper 4 can be completely sleeved outside the heat exchanger 1 and heat exchanger 2. The positioning rod 422 is released, and under the force of the restoring spring 424, the positioning rod 422 enters the positioning hole 43, which can fix the feeding hopper 4. The sealing gasket 44 on the inner side of the feeding hopper 4 can prevent the material from overflowing from between the feeding hopper 4 and heat exchanger 1 and heat exchanger 2.

[0031] Working principle: In use, the feeding hopper 4 is connected to the outlet of the electrolytic manganese cell via the connecting flange 41. The other end of the feeding hopper 4 is then fitted over one end of heat exchanger 1 and heat exchanger 2. During this fitting process, the positioning rod 422 is pulled upwards. The positioning rod 422 compresses the return spring 424 via the connecting rod 423, thus completely fitting the feeding hopper 4 over heat exchanger 1 and heat exchanger 2. Releasing the positioning rod 422 allows it to enter the positioning hole 43 under the force of the return spring 424, thus fixing the feeding hopper 4. The sealing gasket 44 inside the feeding hopper 4 can prevent material from overflowing between the feeding hopper 4 and heat exchangers 1 and 2. The material inside the electrolytic manganese cell is fed into the feeding hopper 4 and enters the heat exchange pipe 302. Cooling water is then fed into heat exchanger 1 from the inlet 201. The cooling water passes through multiple baffles 303 and finally enters heat exchanger 2 from the connecting pipe 304. After passing through multiple baffles 303, it is discharged from the outlet 202. Under the action of the baffles 303, the time inside heat exchangers 1 and 2 is extended, which greatly improves the heat exchange efficiency.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
