Description

Technical Field

[0001] This invention relates to the technical field of steelmaking converter slag treatment equipment, specifically to a hot septic tank water filter barrel structure and its installation method. Background Technology

[0002] The hot quenching tank is one of the main pieces of equipment in the pressurized hot quenching process for steel slag. Its main function is to generate and maintain a certain pressure, allowing the steel slag to cool in stages and rapidly decompose the free calcium oxide in the slag. This process increases the working pressure by approximately 100 to 200 times compared to the atmospheric pressure tank hot quenching process. Under higher pressure conditions, the osmotic pressure of water vapor increases, accelerating the reaction rate between water vapor and free calcium oxide in the steel slag, reducing the quenching time from 10 hours to 2.5 to 3 hours. Furthermore, since the entire process of steel slag treatment is carried out in a largely closed system, it achieves a higher level of cleanliness and is more environmentally friendly compared to existing steel slag treatment technologies.

[0003] To conserve resources, the entire process employs two water circulation systems. The pressurized hot quenching water belongs to the turbid water circulation system. To facilitate the use of this system later, preliminary filtration is required during drainage. Furthermore, one of the conditions for slag discharge in pressurized hot quenching is that the liquid level in the tank reaches zero, necessitating the rapid discharge of cooling water from the hot quenching tank. However, the existing pressurized hot quenching technology uses approximately 130 cubic meters of water throughout the entire process, a significant amount. As the quenching progresses, the steel slag gradually pulverizes, resulting in a large amount of slag being carried into the water. This slag easily clogs drainage pipes, valves, and pumps, increasing filtration pressure and significantly extending the overall drainage time, which is detrimental to system operation. Simultaneously, cleaning the outlet pipes, valves, and pumps is labor-intensive and resource-intensive, increasing workload and potentially damaging equipment such as pipes and valves, thus affecting the overall lifespan of the equipment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a structure and installation method for a hot water filter barrel for hot water sealing tanks, which can effectively and quickly filter the water outlet of the hot water sealing tank and improve the drainage efficiency of the hot water sealing tank, in order to address the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] I. A structure of a heated water filter canister

[0007] The present invention provides a filter barrel structure for a hot-sealing tank, which is installed on the top of the outlet pipe 4 of the hot-sealing tank. It includes a filter barrel 101, a flange pressure ring 2 and a flange base 3. The filter barrel 101 includes a filter barrel body 103, a filter barrel top cover 102 and a filter barrel mounting base 104.

[0008] The flange pressure ring 2 is sleeved on the outer wall of the filter barrel body 103, the flange base 3 is fixedly connected to the top of the outlet pipe 4, and the filter barrel top cover 102 and the filter barrel mounting base 104 are respectively fixedly connected to the top and bottom of the filter barrel body 103.

[0009] The filter barrel mounting base 104 is pressed against the top of the outlet pipe 4 by the cooperation of the flange pressure ring 2 and the flange base 3.

[0010] Furthermore, the hot-sealing container is provided with a hot-sealing container inlet at the top and a hot-sealing container outlet at the bottom; one end of the outlet pipe 4 is connected to the hot-sealing container outlet, and the other end of the outlet pipe 4 is vertically upward and the flange base 3 is fixedly connected to the top of the outer ring.

[0011] Furthermore, the inner diameter of the filter barrel body 103 is adapted to the inner diameter of the outlet pipe 4; the filter barrel top cover 102 is welded and fixed to the top of the filter barrel body 103, and the filter barrel mounting base 104 is annularly welded and fixed to the outer ring of the bottom of the filter barrel body 103.

[0012] Furthermore, the wall thickness L of the filter barrel body 103 satisfies:

[0013] L>C×K×F 冲

[0014] In the formula, C is the impact resistance coefficient of the filter barrel material, and F... 冲 K represents the impact force of the water mixed with slag discharged from the outlet pipe of the hot sealing tank, and K is a correction factor.

[0015] Furthermore, the height H of the filter barrel body 103 satisfies:

[0016] H = V × T + h

[0017] In the formula, V is the slag accumulation rate in the vertical direction of the hot-sealing tank, T is the preset filter barrel cleaning cycle, and h is the reserved cleaning height.

[0018] Furthermore, the filter barrel body 103 is provided with a plurality of transverse filter holes evenly distributed on it. The diameter D of the transverse filter holes is determined as follows:

[0019] Statistically determine the percentage of slag particles of each size range in the hot simmering tank. If the percentage of slag particles larger than D0 is not less than 70%, then set the diameter of the transverse filter holes D = D0.

[0020] Furthermore, the top cover 102 of the filter barrel is evenly provided with a plurality of vertical filter holes, the diameter d and the number n of the vertical filter holes satisfying:

[0021] n×π×d 2 / 4>S0

[0022] In the formula, S0 is the cross-sectional area of ​​the inlet of the hot water tank.

[0023] Furthermore, both the flange pressure ring 2 and the flange base 3 are provided with corresponding bolt holes. The flange pressure ring 2 and the flange base 3 are specifically fixedly connected by bolts and press the filter barrel mounting seat 104.

[0024] Furthermore, both the filter barrel body 103 and the filter barrel top cover 102 are made of 304 stainless steel, and the flange base 3 is specifically welded and fixedly connected to the top of the outlet pipe 4.

[0025] II. A method for installing a hot-sealing water filter cartridge

[0026] Based on the same inventive concept, the present invention also provides an installation method for the hot-sealing tank water filter barrel structure as described above, specifically including the following steps:

[0027] S1, Filter barrel manufacturing and filter hole processing: The filter barrel top cover 102 and the filter barrel mounting base 104 are respectively welded to the top and bottom of the filter barrel body 103, and horizontal filter holes and vertical filter holes are respectively processed on the filter barrel body 103 and the filter barrel top cover 102 according to the preset quantity and size.

[0028] S2, Installation of flange base for water outlet pipe: Connect one end of water outlet pipe 4 to the water outlet of the hot condenser, and weld the other end vertically upward and weld flange base 3 to the top of its outer ring.

[0031] Compared with the prior art, the present invention has the following main advantages:

[0032] 1. This invention installs a vertically upward-facing outlet pipe at the outlet of the hot slugging tank. During operation, the hot slugging tank performs primary grading filtration of large-diameter steel slag particles (particle size greater than 10mm) in the turbid water. By evenly opening a preset number and size of filter holes on the filter barrel body and filter barrel top cover, the medium-diameter steel slag particles are further efficiently graded (more than 70%, particle size greater than 5mm). This effectively prevents steel slag particles larger than medium diameter from damaging water valves, drainage pumps, and other equipment.

[0033] 2. By rationally designing the size and material of the filter bucket, this invention can effectively improve the drainage speed of the hot septic tank, reduce the frequency of manual slag cleaning, significantly reduce labor intensity, and extend the overall service life of the hot septic tank drainage system, ensuring the equipment stability and production continuity of the entire process system.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0039] It should be noted that, depending on the implementation needs, the various steps / components described in this application can be broken down into more steps / components, or two or more steps / components or parts of the operation of steps / components can be combined into new steps / components to achieve the purpose of this invention.

[0040] Example 1: This example provides a hot-sealing water filter tank structure, such as... Figures 1-2 As shown, it mainly includes: filter barrel 101, flange pressure ring 2 and flange base 3. The filter barrel 101 includes filter barrel body 103, filter barrel top cover 102 and filter barrel mounting base 104.

[0041] The flange pressure ring 2 is sleeved on the outer wall of the filter barrel body 103, the flange base 3 is fixedly connected to the top of the outlet pipe 4, and the filter barrel top cover 102 and the filter barrel mounting base 104 are respectively fixedly connected to the top and bottom of the filter barrel body 103.

[0042] The filter barrel mounting base 104 is pressed against the top of the outlet pipe 4 by the cooperation of the flange pressure ring 2 and the flange base 3.

[0043] Furthermore, the hot-sealing container is provided with a hot-sealing container inlet at the top and a hot-sealing container outlet at the bottom; one end of the outlet pipe 4 is connected to the hot-sealing container outlet, and the other end of the outlet pipe 4 is vertically upward and the flange base 3 is fixedly connected to the top of the outer ring.

[0044] Furthermore, the inner diameter of the filter barrel body 103 is adapted to the inner diameter of the outlet pipe 4; the filter barrel top cover 102 is welded and fixed to the top of the filter barrel body 103, and the filter barrel mounting base 104 is annularly welded and fixed to the outer ring of the bottom of the filter barrel body 103.

[0045] Furthermore, the wall thickness L of the filter barrel body 103 satisfies:

[0046] L>C×K×F 冲

[0047] In the formula, C is the impact resistance coefficient of the filter barrel material, and F... 冲 K represents the impact force of the water mixed with slag discharged from the outlet pipe of the hot sealing tank, and K is a correction factor.

[0048] Furthermore, the height H of the filter barrel body 103 satisfies:

[0049] H = V × T + h

[0050] In the formula, V is the slag accumulation rate in the vertical direction of the hot-sealing tank, T is the preset filter barrel cleaning cycle, and h is the reserved cleaning height.

[0051] Furthermore, the filter barrel body 103 is provided with a plurality of transverse filter holes evenly distributed on it. The diameter D of the transverse filter holes is determined as follows:

[0052] Statistically determine the percentage of slag particles of each size range in the hot simmering tank. If the percentage of slag particles larger than D0 is not less than 70%, then set the diameter of the transverse filter holes D = D0.

[0053] Furthermore, the top cover 102 of the filter barrel is evenly provided with a plurality of vertical filter holes, the diameter d and the number n of the vertical filter holes satisfying:

[0054] n×π×d 2 / 4>S0

[0055] In the formula, S0 is the cross-sectional area of ​​the inlet of the hot water tank.

[0056] Furthermore, both the flange pressure ring 2 and the flange base 3 are provided with corresponding bolt holes. The flange pressure ring 2 and the flange base 3 are specifically fixedly connected by bolts and press the filter barrel mounting seat 104.

[0057] Furthermore, both the filter barrel body 103 and the filter barrel top cover 102 are made of 304 stainless steel, and the flange base 3 is specifically welded and fixedly connected to the top of the outlet pipe 4.

[0058] Example 2: This example provides a hot-pressed water filtration filter barrel structure. The filter barrel body 103 has a diameter of 370mm (consistent with the diameter of the outlet pipe) and a wall thickness of 3mm, which can withstand the impact of water mixed with sludge, ensuring that the barrel body does not deform.

[0059] Furthermore, according to statistics, after the hot-quenching process is completed, the percentage of slag particles of various sizes in the tank relative to the total slag particles is shown in the table below:

[0060] Particle size range Quantity (ten thousand tons) percentage 0-5mm 108620.80 29.40％ 5-10mm 111207.01 30.10％ 10-20mm 105295.68 28.50％ 20-40mm 42118.27 11.40％ 40mm or more 2216.75 0.60％ total 369458.52 100.00％

[0061] 70% of the steel slag has a diameter of ≥5mm, and 30% has a diameter of <5mm. Therefore, the diameter of the transverse filter holes in the barrel is 5mm and they are evenly distributed, which can effectively filter 70% of the particles in the turbid circulating water and prevent pipe and valve blockage.

[0062] Furthermore, the height of the filter barrel 103 is 100mm, and the sludge accumulation cycle of more than 5mm in the vertical direction of the hot sealing tank is 6mm / d. This ensures that the sludge accumulation height in the tank does not exceed the top cover of the filter barrel within 15 days, ensuring that the top cover has normal drainage function and meeting the height limit of the reserved cleaning space.

[0063] Furthermore, the filter tank top cover 102 is provided with 980 vertical filter holes with a diameter of 8mm, so that the total area of ​​the drain holes is larger than the cross-sectional area of ​​the inlet, which can effectively prevent water accumulation in the tank.

[0064] Furthermore, both the filter barrel body 103 and the filter barrel top cover 102 are made of 304 stainless steel, which mainly serves to prevent water vapor corrosion during turbid water circulation and avoid damage to the filter barrel due to water mixing and sludge erosion and corrosion.

[0065] Furthermore, the flange pressure ring 2 has an outer diameter of 412mm and an inner diameter of 372mm, and adopts a 6-hole flange with a hole diameter of Φ10mm; the flange base 3 has an outer diameter of 412mm and an inner diameter of 372mm, and also adopts a 6-hole flange with a hole diameter of Φ10mm.

[0066] Example 3: Based on the same inventive concept, this example also provides an installation method for the hot-sealing tank water filter barrel structure as described above, such as... Figure 3 As shown, the specific steps include the following:

[0067] S1, Filter barrel manufacturing and filter hole processing: The filter barrel top cover 102 and the filter barrel mounting base 104 are respectively welded to the top and bottom of the filter barrel body 103, and horizontal filter holes and vertical filter holes are respectively processed on the filter barrel body 103 and the filter barrel top cover 102 according to the preset quantity and size.

[0068] S2, Installation of flange base for water outlet pipe: Connect one end of water outlet pipe 4 to the water outlet of the hot condenser, and weld the other end vertically upward and weld flange base 3 to the top of its outer ring.

[0069] S3, flange pressure ring installation: The flange pressure ring 2 is fitted onto the outer ring of the filter barrel body 103 and the flange pressure ring 2 is pressed onto the filter barrel mounting base 104;

[0070] S4, Filter barrel fixing: The flange pressure ring 2 and the flange base 3 are fixedly connected by bolts, and the filter barrel mounting seat 104 is pressed to fix the filter barrel on the top of the outlet pipe of the hot condenser.

[0071] Furthermore, all parts of this application that are not described in detail are the same as or implemented using existing technology.

[0072] In summary:

[0073] 1. This invention installs a vertically upward-facing outlet pipe at the outlet of the hot slugging tank. During operation, the hot slugging tank performs primary grading filtration of large-diameter steel slag particles (particle size greater than 10mm) in the turbid water. By evenly opening a preset number and size of filter holes on the filter barrel body and filter barrel top cover, the medium-diameter steel slag particles are further efficiently graded (more than 70%, particle size greater than 5mm). This effectively prevents steel slag particles larger than medium diameter from damaging water valves, drainage pumps, and other equipment.
