Description

Technical Field

[0001] The utility model belongs to the technical field of sintering equipment transformation, and more specifically relates to a material temperature raising pool used in vanadium-titanium-iron powder ore blending. Background Art

[0002] To reduce sintering costs during the sintering process, the proportion of vanadium-titanium-iron powder is often increased. This increase in the proportion of vanadium-titanium-iron powder results in a higher proportion of iron powder with a particle size below 1 mm, making pelletization difficult. This results in poor air permeability in the sintering machine, increased negative pressure, and ultimately poor sintering mineralization and low yields.

[0003] To compensate for the losses caused by the above problems, a hot water mixing tank is often installed to raise the material temperature. The hot water mixing tank recycles the water mist dust removal drainage to raise the material temperature. This method fully reuses the water mist dust removal drainage at a certain temperature, improving the pelletizing effect of the material. However, when using the existing hot water mixing tank, the hot water temperature is often unstable, slightly lower than the preset temperature. In addition, the hot water contains a certain amount of impurities, and directly supplying it to the subsequent pipeline can easily cause pipeline blockage, resulting in unstable water supply and large fluctuations in water supply, which ultimately affects the quality of the sintered ore. Utility Model Content

[0004] The purpose of the utility model is to provide a material temperature raising pool for vanadium-titanium-iron powder ore blending, which can effectively increase the material temperature of the vanadium-titanium-iron powder and improve the overall quality of the sintered ore.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a material temperature raising pool for vanadium-titanium iron powder ore blending, including a water reservoir, a water supply pipe, a steam supply pipe and a mixed water outlet pipe. A first partition and a second partition arranged in parallel are provided in the water reservoir. The upper edge of the first partition is higher than the upper edge of the second partition. The first partition and the second partition separate the water reservoir into a water supply sedimentation area, a steam temperature control area and a hot water outlet area. The water supply pipe is used to supply water to the box water supply sedimentation area, the steam supply pipe is used to supply steam directly to the steam temperature control area, and a mixed water outlet pipe is used to transfer water in the hot water outlet area and supply it to a mixed hot water pipe.

[0006] In one possible implementation, the steam supply pipe includes a gas supply main pipe and a gas supply branch pipe. The gas supply main pipe extends downward to the bottom of the steam temperature control zone. The gas supply branch pipe is connected to the lower end of the gas supply main pipe. The gas supply branch pipe is arranged parallel to the first partition and extends in a horizontal direction. Several steam holes are provided on the gas supply branch pipe.

[0007] In some embodiments, the steam holes are symmetrically arranged in two rows on both sides of the gas supply branch pipe, and the two rows of steam holes are respectively arranged on the upper parts of both sides of the gas supply branch pipe.

[0008] In a possible implementation, the inlet end of the water supply pipe is connected to a water pump located in the hot water outlet area, and the water pump is used to pump hot water in the hot water outlet area and supply the hot water to a mixed water outlet pipe.

[0009] In some embodiments, a water outlet end of a mixed water outlet pipe extends upward to be higher than the water reservoir, and the water outlet end of the mixed water outlet pipe is connected to a mixed hot water pipe.

[0010] In a possible implementation, the water outlet end of the water supply pipe extends downward to the middle of the water supply sedimentation area.

[0011] In a possible implementation, the first partition is 15 mm to 25 mm higher than the second partition.

[0012] In one possible implementation, a defoaming net is also provided in the water reservoir. The defoaming net is horizontally arranged in the steam temperature control zone and close to the upper edge of the steam temperature control zone. The defoaming net is used to eliminate steam bubbles in the steam temperature control zone.

[0013] In a possible implementation, a filter screen connected to the upper edge of the first partition is further provided in the water reservoir. The filter screen extends obliquely upward toward the side close to the water supply pipe and is used to filter water in the water supply sedimentation area.

[0014] In one possible implementation, the side of the second partition is also connected to an inclined water guide plate located in the hot water outlet area. The inclined water guide plate is connected to the upper part of the first partition and extends obliquely downward toward the side close to a mixed water outlet pipe, for guiding water to flow downward to the hot water outlet area.

[0015] The scheme shown in the embodiment of the present application is compared with the existing technology. The embodiment of the present application provides a material temperature raising pool for vanadium-titanium iron powder ore blending. By setting a first partition and a second partition, the water storage tank is divided into a water replenishment sedimentation zone, a steam temperature control zone and a hot water outlet zone. The water replenishment sedimentation zone can effectively precipitate impurities in the recycled water supplied by the water replenishment pipe. The water at the top of the water replenishment sedimentation zone overflows to the steam temperature control zone through the first partition.

[0024] Please also refer to Figures 1 to 3The material temperature raising tank for vanadium-titanium iron powder blending provided by the present invention is now described. The material temperature raising tank for vanadium-titanium iron powder blending includes a water reservoir 1, a water supply pipe 2, a steam supply pipe 3, and a mixed water outlet pipe 4. A first partition 5 and a second partition 6 are provided in parallel in the water reservoir 1. The upper edge of the first partition 5 is higher than the upper edge of the second partition 6. The first partition 5 and the second partition 6 separate the water reservoir 1 into a water supply sedimentation area 11, a steam temperature control area 12, and a hot water outlet area 13. The water supply pipe 2 is used to supply water to the water supply sedimentation area 11, the steam supply pipe 3 is used to supply steam directly to the steam temperature control area 12, and the mixed water outlet pipe 4 is used to transfer water in the hot water outlet area 13 and supply it to a mixed hot water pipe.

[0025] The material temperature raising pool for vanadium-titanium iron powder blending provided in the present embodiment, compared with the prior art, is a material temperature raising pool for vanadium-titanium iron powder blending provided in the present embodiment, which divides the water reservoir 1 into a water replenishment sedimentation zone 11, a steam temperature control zone 12 and a hot water outlet zone 13 by setting a first partition 5 and a second partition 6. The water replenishment sedimentation zone 11 can effectively precipitate impurities in the recycled water supplied by the water replenishment pipe 2, and the water at the top of the water replenishment sedimentation zone 11 overflows to the steam temperature control zone 12 through the first partition 5, and hot steam is supplied into the steam temperature control zone 12 by using the steam supply pipe 3 to effectively increase the water temperature. The heated water overflows to the hot water outlet zone 13 through the second partition 6, and the water with a certain temperature is supplied to the subsequent process steps through a mixed water outlet pipe 4, thereby meeting the temperature increase requirements of the material and ensuring the production quality of the vanadium-titanium iron powder.

[0026] In this embodiment, the water reservoir 1 is divided into a water replenishment sedimentation area 11, a steam temperature control area 12 and a hot water outlet area 13 by setting a first partition 5 and a second partition 6. At the same time, the height of the first partition 5 is limited to be higher than the second partition 6, so that water tends to overflow from the water replenishment sedimentation area 11 to the steam temperature control area 12, completing the precipitation and purification of the water. Afterwards, the water temperature is increased in the steam temperature control area 12, and then overflows from the position of the second partition 6 to the hot water outlet area 13, realizing the layer-by-layer supply of water and meeting the requirement for increasing the water supply temperature.

[0027] In one possible implementation, see Figures 1 to 3 The steam supply pipe 3 includes a gas supply main pipe 31 and a gas supply branch pipe 32. The gas supply main pipe 31 extends downward to the bottom of the steam temperature control zone 12. The gas supply branch pipe 32 is connected to the lower end of the gas supply main pipe 31. The gas supply branch pipe 32 is arranged parallel to the first partition plate 5 and extends in the horizontal direction. A plurality of steam holes 33 are provided on the gas supply branch pipe 32.

[0028] In this embodiment, the steam supply pipe 3 is in the form of a combination of an air supply main pipe 31 and an air supply branch pipe 32. The air supply main pipe 31 extends downward to the bottom of the temperature-controlled steam temperature control zone 12, and supplies hot steam to the air supply branch pipe. The multiple steam holes 33 set on the air supply branch pipe 32 discharge hot steam outward synchronously, thereby achieving a uniform increase in the water temperature in the steam temperature control zone 12, ensuring the uniformity of the temperature rise, and allowing the heated water to overflow to the hot water outlet area 13 through the second partition 6 in an orderly manner, providing hot water with a suitable temperature for subsequent steps.

[0029] For some examples, see Figures 1 to 3 The steam holes 33 are symmetrically arranged in two rows on both sides of the gas supply branch pipe 32 , and the two rows of steam holes 33 are respectively arranged on the upper parts of both sides of the gas supply branch pipe 32 .

[0030] In this embodiment, two rows of steam holes 33 are provided to improve the efficiency of hot steam discharge. The two rows of steam holes 33 are located on the upper portions of the air branch pipe on either side, and can simultaneously discharge hot steam outward and upward, increasing the contact area between the hot steam and the water, thereby evenly heating the water in the steam temperature control zone 12.

[0031] In one possible implementation, see Figures 1 to 3 The inlet end of the water supply pipe 2 is connected to a water pump 7 located in the hot water outlet area 13 , and the water pump 7 is used to pump hot water in the hot water outlet area 13 and supply the hot water to a mixed water outlet pipe 4 .

[0032] In this embodiment, the water pump 7 is connected to the water inlet end of a mixed water outlet pipe 4, which can orderly introduce the water in the hot water outlet area 13 into the mixed water outlet pipe 4, providing a stable water source for subsequent steps. The outlet end of the mixed water outlet pipe 4 extends upward. To meet the requirements of supplying water to the mixed water outlet pipe 4, the outlet end of the water supply pipe 2 extends downward to the middle of the water supply sedimentation area 11. The water fed in can be close to the middle and lower parts of the lake water sedimentation area.

[0033] For some examples, see Figures 1 to 3 The outlet end of a mixed water outlet pipe 4 extends upward to be higher than the water reservoir 1, and the outlet end of a mixed water outlet pipe 4 is connected to a mixed hot water pipe.

[0034] In this embodiment, the water inlet end of a mixed water outlet pipe 4 draws water to the water outlet end through a water pump 7 and supplies it to a mixed hot water pipe. The mixed water outlet pipe 4 extends upward to above the water reservoir 1 and is connected to a mixed hot water pipe to achieve orderly supply of water.

[0035] In one possible implementation, see Figures 1 to 3The outlet end of the water supply pipe 2 extends downward to the middle of the water supply sedimentation area 11. In order to facilitate the effective precipitation of impurities in the water into the water supply sedimentation area 11 and prevent impurities from overflowing with the water flow to the steam temperature control area 12, the water supply pipe 2 guides water into the middle and lower part of the water supply sedimentation area 11, preventing impurities from entering the upper part of the water supply sedimentation area 11 and overflowing with the water to the steam temperature control area 12, effectively improving the cleanliness of the water flow and avoiding clogging of subsequent pipelines.

[0036] In one possible implementation, see Figures 1 to 3 The height of the first partition 5 is 15mm to 25mm greater than the height of the second partition 6. The height difference can achieve layer-by-layer overflow of water, preventing water that has not settled well or contains steam bubbles from entering subsequent processes.

[0037] In one possible implementation, see Figures 1 to 3 A defoaming net 14 is also provided in the water reservoir 1. The defoaming net 14 is horizontally arranged in the steam temperature control zone 12 and is arranged close to the upper edge of the steam temperature control zone 12. The defoaming net 14 is used to eliminate steam bubbles in the steam temperature control zone 12.

[0038] In this embodiment, the fire protection net installed in the water reservoir 1 can eliminate bubbles in the water, preventing the bubbles from escaping upward into the hot water outlet area 13, thereby avoiding affecting the water supply of the mixed water supply pipe 2 to the subsequent work steps, ensuring the stability of the water supply flow rate, and achieving a good warming effect.

[0039] In one possible implementation, see Figures 1 to 3 A filter screen 15 connected to the upper edge of the first partition plate 5 is further provided in the water reservoir 1. The filter screen 15 extends obliquely upward toward the side close to the water supply pipe 2 and is used to filter the water in the water supply sedimentation area 11.

[0040] In this embodiment, the filter 15 is provided to block floating debris in the water supply settling area 11, preventing it from overflowing into the steam temperature control area 12 and affecting subsequent pipeline transportation. The filter 15 is tilted upward toward one side of the water supply pipe 2 to ensure comprehensive filtration of the water and prevent the leakage of impurities.

[0041] In one possible implementation, see Figures 1 to 3 The side of the second partition 6 is also connected to an inclined water guide plate 16 located in the hot water outlet area 13. The inclined water guide plate 16 is connected to the upper part of the first partition 5 and extends obliquely downward toward the side close to the mixed water outlet pipe 4, for guiding water to flow downward to the hot water outlet area 13.

[0042] In this embodiment, by setting an inclined water guide plate 16 in the hot water outlet area 13, effective guidance of the water flow can be achieved, avoiding splashing bubbles when the water flows into the hot water outlet area 13, avoiding gas from entering the mixed water outlet pipe 4 to affect the stable supply of water flow, ensuring the water supply stability of the mixed water outlet pipe 4, effectively heating the material, and ensuring the production quality of vanadium titanium iron powder.

[0043] The material temperature raising pool used for vanadium-titanium iron powder ore blending is divided into a water replenishment sedimentation zone 11, a steam temperature control zone 12 and a hot water outlet zone 13 by setting a first partition 5 and a second partition 6. The water replenishment sedimentation zone 11 can effectively precipitate impurities in the recycled water supplied by the water replenishment pipe 2. The water at the top of the water replenishment sedimentation zone 11 overflows to the steam temperature control zone 12 through the first partition 5. Hot steam is supplied to the steam temperature control zone 12 through the steam supply pipe 3 to effectively increase the water temperature. The heated water overflows to the hot water outlet zone 13 through the second partition 6. The water with a certain temperature is supplied to the subsequent process steps through a mixed water outlet pipe 4, which meets the temperature increase requirements of the material and ensures the production quality of the vanadium-titanium iron powder.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
