Description

Technical Field

[0001] The utility model belongs to the technical field of steel slag recycling, and in particular relates to a steel slag reverse immersion tank type heat-stuffing water supply and drainage assembly and a steel slag heat-stuffing device. Background Art

[0002] Converter slag is a waste slag produced by converter steelmaking. It is a liquid with a temperature of more than 1400℃ when it is out of the furnace. Tank hot stuffing is a process for treating slag. Usually, the crushed slag is connected to a solid tank and placed in a hot stuffing tank. The slag is cooled by spraying water on the top of the hot stuffing tank. At the same time, the slag reacts with water inside the slag to hydrolyze, and finally the slag-iron separation is achieved and the free CaO and MgO in the slag are digested.

[0003] At present, conventional hot stuffy tanks all adopt the form of top water spraying and bottom water drainage. A spray pipe is set on the top of the hot stuffy tank. After the converter slag is placed in the hot stuffy tank, water is added to the tank through the spray pipe. However, this water adding method is to add water from the top to the bottom. It is not easy for water to contact with the slag at the bottom, resulting in that the heat of the slag cannot be fully utilized, resulting in uneven digestion reaction of the slag and water. In order to fully react, the stuffy cycle can only be extended, affecting the slag treatment efficiency. Utility Model Content

[0049] Please also read Figures 1 to 6 , the utility model provides a description of the steel slag reverse immersion tank type heat-stuffing water supply and drainage assembly. The steel slag reverse immersion tank type heat-stuffing water supply and drainage assembly includes an inlet and outlet water pipe 1, a water supply component 2 and a drainage component 3. The inlet and outlet water pipe 1 is arranged below the heat-stuffing tank 6, and the two ends of the inlet and outlet water pipe 1 form a first end and a second end respectively, and the first end is connected to the bottom of the heat-stuffing tank 6; the water supply component 2 has a water supply pipe 21, and the water outlet end of the water supply pipe 21 is connected to the second end to form a water supply path; the drainage component 3 has a drainage pipe 31, and the water inlet end of the drainage pipe 31 is connected to the second end to form a drainage path; wherein, the water supply pipe 21 and the drainage pipe 31 are selectively connected to the inlet and outlet water pipe 1.

[0050] During specific implementation, the inlet and outlet water pipes 1, the water supply pipe 21 and the drainage pipe 31 form a three-way pipe structure, the water supply pipe 21 and the inlet and outlet water pipes 1 form a water supply path for unidirectional flow from the water supply pipe 1 to the inlet and outlet water pipes 1, and the inlet and outlet water pipes 1 and the drainage pipe 31 form a drainage path for unidirectional flow from the inlet and outlet water pipes 1 and the drainage pipe 31, and either the water supply path or the drainage path is opened.

[0051] Compared with the prior art, the steel slag reverse immersion tank type hot stuffy water supply and drainage assembly provided in this embodiment can pass water from the bottom of the hot stuffy tank 6 from bottom to top.

Either the water supply pipe 21 or the drainage pipe 31 is opened, and the water supply operation and the drainage operation are separated, which can ensure timely water supply and timely drainage.

[0052] In some embodiments, see Figure 1 The water supply pipe 21 is provided with a water inlet check valve 23, and the drainage pipe 31 is provided with a drainage check valve 33. The presence of the water inlet check valve 23 and the drainage check valve 33 can make the water in the water supply pipe 21 and the drainage pipe 31 flow in one direction, avoid the phenomenon of water backflow in the water supply pipe 21, and ensure the normal operation of water supply and drainage.

[0056] Optionally, the drainage pump 32 may be a centrifugal pump or a submersible pump, and of course, a water pump of the same type as the water supply pump 22 may also be selected.

[0057] Based on the unified inventive concept, see Figures 2 to 4The present application also provides a steel slag hot stuffing device, comprising a pressure tank 5, a hot stuffing tank 6, a steel slag reverse immersion tank type hot stuffing water supply and drainage assembly as in any one of the above embodiments, and an elastic seal 7.

[0058] It should be noted that the pressure tank 5 and the heat-stifling tank 6 are arranged at intervals to improve the heat preservation effect of the heat-stifling tank 6 and prevent heat diffusion from affecting the temperature of the working environment.

[0059] It should be noted that the hot stuffing tank 6 is filled with steel slag and then put into the pressure tank 5. After the hot stuffing is completed, the entire hot stuffing tank 6 is taken out and put into a hot stuffing tank 6 that has not been hot stuffed, so as to speed up the overall hot stuffing efficiency of the steel slag.

[0060] During specific implementation, a suspension arm is provided on the outer periphery of the top of the hot stuffy tank 6, which can be connected to the suspension arm through a rope to lift and transport the hot stuffy tank 6.

[0061] It should be noted that the water inlet and outlet pipes 1 and the pressure tank 5 are relatively fixed.

[0062] Compared with the prior art, the slag hot stuffing device provided in this embodiment can be fed with water from the bottom of the hot stuffing tank 6 from bottom to top. When water is fed from the bottom, the water can flood all the slag and contact all the slag from the bottom, ensuring the utilization of heat; the flooding area is large, so that the contact area between the slag and the water is increased, ensuring the digestion effect of the slag and the water, improving the reaction efficiency, shortening the overall working cycle, and reducing the cost.

The water inlet and outlet water pipes 1 are used for both water inlet and drainage, saving the use cost. Compared with the existing spray pipe, the maintenance of the spray pipe is saved, and the maintenance cost of the overall equipment is reduced. The provision of the elastic sealing member 7 can seal the gap between the water inlet and outlet holes 61 and the water inlet and outlet pipes 1 to prevent water from overflowing, thereby ensuring the normal operation of water supply and drainage.

[0063] In some embodiments, an interception net is provided at the water inlet and outlet holes 61. The interception net can intercept the steel slag above the interception net to prevent the steel slag from falling into the water inlet and outlet pipes 1 and affecting the normal operation of the water inlet and outlet pipes 1; water can enter or pass through the hot stuffy tank 6 through the mesh of the interception net without affecting the normal water supply and drainage work.

[0064] In specific implementation, the interception net can be replaced with a filter basin, which is buckled at the bottom of the inner cavity of the hot and stuffy tank 6, as long as the steel slag can be prevented from entering the inlet and outlet water pipes 1.

[0065] In some embodiments, see Figures 2 to 4 The pressure tank 5 includes a cylindrical shell 51 with openings at the top and bottom, and a sealing cover 52 covering the opening at the top of the shell 51. The heat-suffocating tank 6 is arranged inside the shell 51 and is spaced from the shell 51 to form a heat-insulating space. A support seat 53 is provided in the heat-insulating space. The support seat 53 is supported and connected between the shell 51 and the bottom of the heat-suffocating tank 6, and divides the heat-insulating space into a accommodating space and an installation space. The main body of the inlet and outlet water pipe 1 is located in the installation space, and the first end passes through the support seat 53 and connects with the inlet and outlet water hole 61.

[0066] The pressure tank 5 provided in this embodiment has a simple structure. A support seat 53 is provided in the shell 51. The support seat 53 can support the heat-stifling tank 6 and make the heat-stifling tank 6 suspended in the air to facilitate the installation of the inlet and outlet water pipes 1. The sealing cover 52 can cover the shell 51 to seal the accommodating space, thereby making the heat-stifling tank 6 in a closed space to achieve the heat-stifling work of the steel slag. The overall structure is simple and the manufacturing difficulty is low.

[0067] In some embodiments, a swing arm is further provided on the periphery of the housing 51, and the swing end of the swing arm is connected to the sealing cover 52, and the sealing cover 52 is covered or away from the top opening of the housing 51 by the swing arm rotating along its own axis. In specific implementation, a telescopic oil cylinder can be provided, and the two ends of the telescopic oil cylinder are respectively hinged to the swing arm and the periphery of the housing 51. By changing the length of the telescopic oil cylinder, the swing arm is driven to swing, and the sealing cover 52 and the housing 51 are automatically closed and opened, thereby improving the degree of automation of the device.

[0068] In some embodiments, see Figure 2 and Figure 4 The inner wall of the shell 51 is provided with an annular clamping protrusion 54, and the outer wall of the heat-stifling pot 6 is provided with a clamping ring groove 62 corresponding to the clamping protrusion 54, and the clamping ring groove 62 is clamped and matched with the clamping protrusion 54. The clamping protrusion 54 and the clamping ring groove 62 cooperate, so that the shell 51 can fix the heat-stifling pot 6, ensuring the stability of the heat-stifling pot 6 during the heat-stifling process. The setting of the clamping protrusion 54 makes a gap between the heat-stifling pot 6 and the shell 51, further improving the heat preservation effect of the heat-stifling pot 6.

[0069] In some embodiments, see Figure 4The bottom of the hot stuffy pot 6 is provided with a support protrusion 63, and the bottom end of the support protrusion 63 abuts against the support seat 53. The support protrusion 63 provides an installation space for the inlet and outlet water pipes 1, and at the same time, there is a gap between the bottom of the hot stuffy pot 6 and the support seat 53, thereby improving the heat preservation effect of the hot stuffy pot 6.

[0070] In some embodiments, see Figure 4 The support seat 53 is provided with a clamping hole, and a clamping block 4 is provided on the outer periphery of the inlet and outlet pipe 1 corresponding to the clamping hole, and the clamping block 4 is clamped and matched with the clamping hole; an elastic sealing member 7 is provided between the inlet and outlet pipe 1 and the hot stuffy tank 6. The clamping hole 53 can cooperate with the clamping block 4, so that the inlet and outlet pipe 1 and the support seat 53 are relatively fixed. After the hot stuffy tank 6 is installed in the housing 52, the elastic sealing member 7 can be squeezed to achieve the purpose of sealing the top opening of the inlet and outlet pipe 1 and the inlet and outlet hole 61, so as to prevent water from overflowing from the gap between the inlet and outlet pipe 1 and the hot stuffy tank 6 during the supply and drainage process.

[0071] In some embodiments, see Figure 5 The elastic sealing member 7 includes an elastic shell 71, an upper mounting plate 72, a lower mounting plate 73 and an elastic member 74.

The upper mounting plate 72 and the lower mounting plate 73 are connected to the elastic member 74 respectively. Under the push of the elastic member 74 itself, the upper mounting plate 72 and the lower mounting plate 73 are moved away from each other. The upper mounting plate 72 and the lower mounting plate 73 have large plate surface areas, large contact areas with the bottom of the hot stuffy tank 6, and large contact areas with the inlet and outlet water pipes 1, which increases the deformation stability of the elastic member 74 and the elastic housing 71. The elastic housing 71 has a deformation amount and can be deformed multiple times without damage, thereby improving the use effect.

[0072] Optionally, the elastic member 74 is a spring, which has good deformation continuity and elasticity and can meet the requirements of the elastic member 74. Of course, a tower spring can also be used as long as it can drive the upper mounting plate 72 and the lower mounting plate 73 to move away from each other. They are not listed here one by one.

[0073] In specific implementation, the upper and lower ends of the elastic shell 71 are respectively provided with snap rings 75, and the upper and lower snap rings are respectively abutted against the corresponding upper mounting plate 72 and lower mounting plate 73 to prevent the upper mounting plate 72 and / or the lower mounting plate 73 from separating from the elastic shell 71.

[0074] In a specific implementation, the clamping ring 75 and the elastic shell 71 are integrally formed.

[0075] In specific implementation, the elastic sealing member 7 is an elastic rubber ball, which has a water passage penetrating in the up-down direction, and the two ends of the water passage are respectively connected with the water inlet and outlet and the water inlet and outlet pipe 1. When the hot stuffy pot 6 is placed in the shell 51, the elastic rubber ball will be pressed downward, and the elastic rubber ball will be deformed to provide a reverse pre-tightening force, thereby sealing the gap between the water inlet and outlet pipe 1 and the water inlet and outlet hole 61.
