Description

Technical Field

[0002] Vanadium pentoxide is a yellow metallic compound, which is widely used in industries such as metallurgy and chemical engineering. At present, a melting furnace is required to melt raw materials during the production of vanadium pentoxide. Most of the existing melting furnaces of this kind only generate high temperature inside the furnace and use the high temperature to melt the raw materials.

[0003] However, in the specific production process, it is found that the current melting furnace cannot heat the raw materials entering the furnace body evenly and efficiently, resulting in a small amount of uncompletely melted raw materials in the melted product. The reasons are as follows: firstly, the temperature in each area inside the reverberatory furnace is uneven, and the temperature in the area near the burner is higher than that in the area far from the burner; secondly, too much heat dissipates at the furnace top and the furnace bottom inside the reverberatory furnace, so that there is a certain difference between the temperature inside the reverberatory furnace and the expected temperature, resulting in incomplete melting of the raw materials. Summary of the Utility Model

[0004] The utility model provides a vanadium pentoxide raw material melting furnace, which is used to solve the technical problem that the melting furnace in the prior art cannot heat the vanadium pentoxide raw materials entering it evenly and efficiently.

[0029] The present utility model has the following beneficial effects compared with the prior art:

[0030] The vanadium pentoxide raw material melting furnace provided by the utility model comprises a furnace body, a main burner, a sub-burner and a heat reflection part. A feeding port is arranged at the top of the furnace body, and a discharging port is arranged at the bottom of the furnace body. Among them, the feeding port is used to inject vanadium pentoxide into the furnace body, and the discharging port is used to discharge the product after the raw materials are melted out of the furnace body.

The heat reflection part makes the temperature inside the furnace body closer to the expected temperature, so that the vanadium pentoxide in the furnace body is melted more completely. Therefore, the vanadium pentoxide raw material melting furnace can heat the vanadium pentoxide raw materials entering it more evenly and efficiently, making the raw materials completely melted in it.

Specific embodiments

[0038] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0039] Embodiment:

[0040] The vanadium pentoxide raw material melting furnace provided by the present utility model is as Figure 1 and Figure 2 shown, and it includes a furnace body 100, a main burner 200, an auxiliary burner 300, and a heat reflecting part 400, wherein:

[0041] A feeding port 110 is arranged at the top of the furnace body 100, and a discharging port 120 is arranged at the bottom of the furnace body 100. Among them, the feeding port 110 is used to inject vanadium pentoxide into the furnace body 100, and the discharging port 120 is used to discharge the product after the raw materials are melted from the furnace body 100. The main burner 200 and the auxiliary burner 300 are respectively installed on the left side wall and the right side wall of the furnace body 100. Both the main burner 200 and the auxiliary burner 300 are used to generate high temperature inside the furnace body 100. It should be noted that the burner is the same as the prior art, and it is used for the ignition of fuel and the stabilization of the flame.

[0042] The heat reflecting part 400 is installed on the top and / or bottom of the furnace body 100, so as to reflect the heat at the top and / or bottom of the furnace body 100 to the middle part of the furnace body 100. As an alternative implementation of this embodiment, the heat reflecting part 400 in this embodiment is installed on the top of the furnace body 100, so as to reflect part of the heat reaching the top of the furnace body 100. As another alternative implementation of this embodiment, the heat reflecting part 400 in this embodiment is installed on the bottom of the furnace body 100, so as to reflect part of the heat reaching the bottom of the furnace body 100. Of course, the best implementation of this embodiment is: the above heat reflecting parts 400 are installed on both the top and the bottom of the furnace body 100, so as to facilitate reflecting part of the heat reaching the top and the bottom of the furnace body 100 into the furnace body 100, which can reduce the heat loss of the furnace body 100, ensure that the temperature inside the furnace body 100 is closer to the expected temperature, and be more energy-saving.

[0043] During use, the vanadium pentoxide raw material is injected into the furnace body 100 from the feeding port 110, and the main burner 200 and the auxiliary burner 300 are used to generate high temperature inside the furnace body 100. Since the main burner 200 and the auxiliary burner 300 are respectively located on the left side wall and the right side wall of the furnace body 100, this setting can make the temperature of each area inside the furnace body 100 more balanced and is also more convenient to adjust the temperature inside the furnace body 100. The heat inside the furnace body 100 melts the vanadium pentoxide raw material to obtain a product, and the obtained product is discharged from the above discharge port 120. During the melting process, when part of the heat inside the furnace body 100 is transferred to the bottom and / or top of the furnace body 100, it is reflected by the heat reflecting parts 400 at the bottom and / or top to the middle part of the furnace body 100, which can reduce the heat dissipation amount at the top and / or bottom, so that the temperature inside the furnace body 100 is closer to the expected temperature, and thus the vanadium pentoxide can be melted more completely.

[0044] Through the above structure, the main burner 200 on the left side wall and the auxiliary burner 300 on the right side wall ensure that the temperature of each area inside the furnace body 100 is more balanced, making the melting effect of the vanadium pentoxide raw material entering each area of the furnace body 100 more uniform. The heat reflecting part 400 makes the temperature inside the furnace body 100 closer to the expected temperature, so that the vanadium pentoxide in the furnace body 100 is melted more completely. Therefore, the vanadium pentoxide raw material melting furnace can heat the vanadium pentoxide raw material entering it more evenly and efficiently, so that the raw material is completely melted in it.

[0045] An alternative implementation of this embodiment is as follows: the above heat reflecting part 400 includes a first reflecting platform 410, a second reflecting platform 420, and a third reflecting platform 430, where:

[0046] The first reflector 410 is arranged at the upper right corner inside the furnace body 100, and the second reflector 420 is arranged at the upper left corner inside the furnace body 100. In this way, the first reflector 410 and the second reflector 420 reflect the heat reaching the two side corners at the top of the furnace body 100 to the middle of the furnace body 100. The feeding port 110 is located between the first reflector 410 and the second reflector 420, that is, the vanadium pentoxide raw material falls into the interior of the above-mentioned furnace body 100 between the first reflector 410 and the second reflector 420. Optionally, the first reflector 410 and the second reflector 420 together cover most of the top of the furnace body 100, so as to better reflect the heat reaching the top of the furnace to the middle of the furnace body 100. As another alternative implementation of this embodiment, the first reflector 410 covers the upper right corner of the top of the furnace body 100, the second reflector 420 covers the upper left corner of the top of the furnace body 100, a fifth reflector is arranged at the front upper corner of the top of the furnace, and a fourth reflector is arranged at the rear upper corner of the top of the furnace.

[0047] The third reflector 430 is arranged at the lower left corner inside the furnace body 100. The third reflector 430 covers the bottom of the furnace body 100. The discharge port 120 is opened at the bottom of the right side wall of the furnace body 100, and the discharge port 120 is docked with the third reflector 430. In this way, the heat reaching the bottom of the furnace body 100 is reflected back to the middle of the furnace body 100 by the third reflector 430.

[0048] In this way, the first reflector 410, the second reflector 420 and the third reflector 430 are respectively arranged at the top and the bottom of the furnace body 100, which can more effectively reduce heat dissipation. After the raw material driven by the heat in the furnace body 100 floats upward and hits the first reflector 410 or the second reflector 420 on the top of the furnace body 100, it is closer to the middle of the furnace body 100, so that it can be closer to the high temperature and can be smoothly melted and fall to the bottom of the furnace.

[0049] Optionally, the first reflector 410 and / or the second reflector 420 and / or the third reflector 430 in this embodiment is a stepped structure. Specifically, the first reflector 410, the second reflector 420 and the third reflector 430 are all stepped structures. Of course, as Figure 1 shown, it can also be that the first reflector 410 or the second reflector 420 or the third reflector 430 is a stepped structure. As another implementation of this embodiment, as Figure 2 shown, the first reflector 410, the second reflector 420 and the third reflector 430 in this embodiment are all ramp platforms. And the first reflector 410 is inclined from left to right and downward, the second reflector 420 is inclined from right to left and downward, and the third reflector 430 is inclined from left to right and downward.

[0050] When both the first reflector 410 and the second reflector 420 are ramp-shaped platforms, the vanadium pentoxide raw materials slapped on them can not only be closer to the middle of the furnace body 100 and closer to the high temperature, so as to be melted more smoothly, but also the ramp-shaped platforms are more conducive to the products obtained after melting falling or sliding into the furnace body 100.

[0051] Optionally, the main burners 200 and the auxiliary burners 300 in this embodiment are arranged in pairs, that is, the numbers of the main burners 200 and the auxiliary burners 300 are the same. The numbers of the main burners 200 and the auxiliary burners 300 are determined according to the size of the furnace body 100. When the furnace body 100 is larger, more of the above-mentioned main burners 200 and auxiliary burners 300 are provided. Specifically, the numbers of the above-mentioned main burners 200 and auxiliary burners 300 are both 1, or 2, or 3.

[0052] Since a large amount of flue gas will be generated during the process of melting the raw materials and during the combustion of the fuel at the main burners 200 and the auxiliary burners 300, therefore, in this embodiment, a smoke exhaust assembly 500 is further provided outside the above-mentioned furnace body 100. The smoke exhaust assembly 500 has an air inlet. A smoke exhaust passage 411 communicating with the inside of the furnace body 100 is opened in the middle and lower part of the first reflector 410. The smoke exhaust passage 411 penetrates through the right side wall of the furnace body 100. The air inlet of the smoke exhaust assembly 500 is communicated with the smoke exhaust passage 411. With the help of the above-mentioned smoke exhaust passage 411 and the smoke exhaust assembly 500, the flue gas generated in the furnace body 100 can be conveniently discharged.

[0053] Optionally, the above-mentioned smoke exhaust assembly 500 includes an exhaust duct 510 and an induced draft fan 530, wherein:

[0054] One end of the exhaust duct 510 constitutes the above-mentioned air inlet. One end of the exhaust duct 510 is connected to the outer wall of the above-mentioned furnace body 100, and one end of the exhaust duct 510 is butted against the above-mentioned smoke exhaust passage 411. The induced draft fan 530 is installed at the other end of the exhaust duct 510. Of course, a power supply is also included for supplying power to the induced draft fan 530 so that the induced draft fan 530 can operate. When the induced draft fan 530 operates, the flue gas in the furnace body 100 is drawn away through the smoke exhaust passage 411 and the exhaust duct 510. Of course, the section of the exhaust duct 510 close to the furnace body 100 can be placed in the water of the water tank. Since the flue gas discharged from the exhaust duct 510 contains a high amount of heat, this part of the heat will heat the exhaust duct 510. When the exhaust duct 510 is placed in the water of the water tank, the preheat of the flue gas can be used to heat the water in the water tank, thus achieving the effect of waste heat utilization. Moreover, heat dissipation fins can be provided on the outer wall of the exhaust duct 510, and the heat dissipation fins are also placed in the water of the water tank, so as to better transfer the heat to the water in the water tank. The heated water can be diverted to the washbasin or other places in the enterprise where hot water is needed.

[0055] Since the flue gas generated in the furnace body 100 contains a lot of dust, if this dust is discharged, it will pollute the environment. Therefore, a dust removal component 520 is also connected in the exhaust duct 510 of the smoke exhaust component 500 provided in this embodiment. In this way, during the process of the flue gas traveling to the induced draft fan 530, the dust removal component 520 will remove most of the dust in the flue gas, thus preventing this part of the dust from being discharged into the external atmosphere.

[0056] Optionally, the above-mentioned dust removal component 520 includes a cyclone dust collector 521 and a bag dust collector 522, where:

[0057] The cyclone dust collector 521 is located between the air inlet and the induced draft fan 530. In this way, the flue gas coming out of the furnace body 100 will first reach the above-mentioned cyclone dust collector 521. The cyclone dust collector 521 makes the flue gas rotate, and with the help of centrifugal force, separates the dust in the flue gas from the air flow and traps it on the wall of the device. Then, with the help of gravity, the dust falls into the collection area, thus removing part of the dust in the flue gas. The bag dust collector 522 is arranged between the cyclone dust collector 521 and the induced draft fan 530. In this way, the flue gas from which part of the dust has been removed by the cyclone dust collector 521 will flow to the bag dust collector 522. Using the filtering effect of the bags in the bag dust collector 522, most of the remaining dust in the flue gas is filtered out. The dust content in the flue gas after being filtered by the bag dust collector 522 is less. Finally, the flue gas containing less dust is discharged by the induced draft fan 530.

[0058] Of course, the above-mentioned dust removal component 520 can also be in other forms, as long as it can remove most of the soot in the flue gas.

[0059] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
