Description

Technical Field

[0001] The utility model relates to the technical field of crude copper production and preparation, in particular to a waste heat recovery device for crude copper production. Background Art

[0002] Blister copper production refers to extracting lower-purity copper from copper ore or copper-containing waste through a series of processing and smelting processes. During the production of blister copper, a large amount of heat is generated as the smelting and other processing steps proceed. If this heat is not recycled, it will radiate outward and be wasted. Therefore, a waste heat recovery device for blister copper production is needed.

[0003] After searching, the Chinese patent announcement number is: CN209623388U, which discloses a waste heat recovery device for crude copper production, including a shell, a water outlet pipe is fixedly connected to the top of the shell, a water pump is installed on the side of the water outlet pipe, and the water outlet end of the water pump is connected to a water inlet pipe. When the utility model is in use, the partition blocks the exhaust gas, and the high-temperature exhaust gas heats the water in the heating tube, and the heated water is discharged through the outlet pipe. At the same time, the particulate matter in the exhaust gas settles to the bottom of the outer shell for a long time inside the outer shell, and the brush pushes the exhaust gas particles at the bottom to the right. At this time, the exhaust gas particles fall from the discharge hole into the collection bin. The new waste heat recovery device for crude copper production can recycle the waste heat and heat the water. At the same time, the particles in the exhaust gas are automatically recovered and collected to avoid direct discharge, which protects the environment while improving the utilization efficiency of thermal energy. It is energy-saving and environmentally friendly to use. However, in actual use, the device cannot filter the exhaust gas generated during the crude copper processing well while recovering the heat, and the generated exhaust gas will still pollute the environment, thereby reducing the reliability of the device.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a waste heat recovery device for crude copper production, comprising a distillation box 1, a waste gas pipe 3 is connected to the left side of the top of the distillation box 1, a gas explosion pipe 4 is connected to the bottom of the waste gas pipe 3, a plurality of gas explosion ports 5 are connected to the top of the gas explosion pipe 4, a distillation pipe 6 is connected to the middle of the top of the distillation box 1, a condensation box 7 is fixedly connected to the right side of the top of the distillation box 1, the right side of the distillation pipe 6 is connected to the middle of the left side of the condensation box 7, a DC motor 8 is fixedly connected to the top of the condensation box 7, the output end of the DC motor 8 passes through the condensation box 7 and is fixedly connected to a rotating rod 9, a fan blade 10 is fixedly connected to the outer side of the rotating rod 9, and a filtering mechanism 2 is arranged on the right side of the condensation box 7; a plurality of drainage holes 21 are opened around the bottom of the distillation box 1, a servo motor 22 is fixedly connected to the middle of the bottom end of the distillation box 1, and the output end of the servo motor 22 passes through the distillation box 1 and is fixedly connected to a baffle 23; a water inlet 13 is connected to the rear side of the top of the distillation box 1, and a dust cover 14 is arranged on the top of the water inlet 13;

[0030] Specifically, high-temperature exhaust gas can be transmitted to the explosion pipe 4 through the exhaust pipe 3. On the explosion pipe 4, multiple explosion ports 5 can discharge the high-temperature exhaust gas into the water in the distillation box 1. At this moment, the water in the distillation box 1 removes impurities in the exhaust gas through filtering. In this process, the high-temperature exhaust gas heats the water to boiling to generate steam. Subsequently, the steam is introduced into the condensation box 7 through the distillation pipe 6. At the same time, the DC motor 8 is started, which drives the rotating rod 9 and the fan blades 10 to increase the cooling rate of the steam in the condensation box 7. After cooling, the steam condenses into water again and drips to the bottom of the condensation box 7. Due to the temperature of the distillation box 1, the water is boiled into steam again. This process realizes the distillation cycle. Water can be added to the distillation box 1 through the water inlet 13, and the dust cover 14 prevents impurities from entering the distillation box 1. By starting the servo motor 22, the baffle 23 can be rotated along the drain hole 21, and the sewage after filtering the exhaust gas is discharged from the drain hole 21 in an interlaced or intersecting manner.

[0031] Reference Figure 1 and Figure 2 The filter mechanism 2 includes an air outlet pipe 201, which is connected to the right side of the condensation box 7. A first hollow block 203 is fixedly connected to the middle of the inner wall of the air outlet pipe 201. The right side of the first hollow block 203 is connected to the exhaust pipe 202. A rotating cover 204 is rotatably connected to the right side of the air outlet pipe 201. A plurality of holes 207 are provided on the outer wall of the rotating cover 204. An electric telescopic rod 205 is fixedly connected to the top of the air outlet pipe 201. A second hollow block 206 is fixedly connected to the telescopic end of the electric telescopic rod 205.

[0032] Specifically, starting the electric telescopic rod 205 can drive the second hollow block 206 to move up and down along the first hollow block 203, so as to realize precise control of the steam in the condensation box 7. First, the distance between the second hollow block 206 and the first hollow block 203 is adjusted by moving the electric telescopic rod 205 up and down. The change of this distance will affect the steam pressure in the condensation box 7, thereby realizing the control of the steam. Subsequently, by rotating the rotating cover 204, the holes 207 thereon are aligned with the exhaust pipe 202, and the steam discharge speed is further adjusted. At this time, there are two methods to realize the exhaust speed adjustment of the exhaust pipe 202. The first method is to align the holes 207 on the dense side thereof with the exhaust pipe 202, so that the density of the holes 207 will increase, thereby improving the exhaust speed of the exhaust pipe 202. The second method is to align the holes 207 on the sparse side with the exhaust pipe 202, so that the distribution of the holes 207 will be more sparse, thereby reducing the exhaust speed of the exhaust pipe 202.

[0033] Reference Figure 1 and Figure 3 A handle 11 is fixedly connected to the middle of the front end of the distillation tube 6, the rear side of the handle 11 penetrates the distillation tube 6 and is fixedly connected to a hollow ball shaft 12, and an indicator 24 is fixedly connected to the top of the front side of the distillation tube 6; fixed blocks 18 are fixedly connected to the outer wall of the distillation box 1 all around, a lifting rod 19 is fixedly connected to the bottom of the fixed block 18, and a spring 20 is fixedly connected to the outer side of the lifting rod 19;

[0034] Specifically, the handle 11 can drive the hollow ball shaft 12 to rotate, and the hollow ball shaft 12 can be used to open and close and adjust the gas output of the distillation tube 6. The lifting rod 19 can be fixed by the fixing block 18. The lifting rod 19 can improve the vibration resistance of the device during operation through the spring 20, thereby reducing the noise generated by the device during operation.

[0035] Reference Figure 3 The back of the distillation box 1 is fixedly connected with a controller 15, and the controller 15 is electrically connected to the DC motor 8, the servo motor 22 and the electric telescopic rod 205 respectively; the outer side of the controller 15 is fixedly connected with a housing 16, and the outer side of the housing 16 is rotatably connected with a shield 17;

[0036] Specifically, the controller 15 can control the starting and operating power of the DC motor 8, the servo motor 22 and the electric telescopic rod 205 respectively, the housing 16 can enhance the protection capability of the controller 15, and the protective cover 17 can prevent the controller 15 from being accidentally touched when it is not in use.

[0037] Working principle: Before using the device, the high-temperature exhaust gas can be first introduced into the explosion pipe 4 through the exhaust pipe 3. The explosion pipe 4 can discharge the high-temperature exhaust gas into the water in the distillation box 1 through multiple explosion ports 5 thereon. At this time, the water in the distillation box 1 can filter the impurities in the exhaust gas, and the exhaust gas can heat the water to boiling through high temperature. At this time, the steam generated in the water can be introduced into the condensation box 7 through the distillation pipe 6. At the same time, the DC motor 8 is started to drive the rotating rod 9 and the fan blades 10 to rotate, thereby increasing the cooling speed of the steam in the condensation box 7. The cooled distillation will become water again and drip at the bottom of the condensation box 7. Due to the temperature of the distillation box 1, it is boiled again into steam. At this time, In order to realize the distillation cycle, the waste gas can be filtered while collecting the waste heat, and by starting the electric telescopic rod 205, the second hollow block 206 can be driven to move up and down along the first hollow block 203, so that the steam in the condensation box 7 can be controlled through the holes 207 thereon, and then the rotating cover 204 can be rotated to align the holes 207 thereon with the exhaust pipe 202. At this time, the exhaust speed of the exhaust pipe 202 can be increased by aligning the holes 207 on the dense side thereof, and the exhaust speed of the exhaust pipe 202 can be reduced by aligning the holes 207 on the sparse side thereof with the exhaust pipe 202. The exhaust speed of the exhaust pipe 202 can be adjusted and controlled, thereby improving the practicality of the device.
