Technical Field
[0001] The utility model relates to the technical field of blast furnace water slagging, in particular to a self-weight slag-discharging type bottom filter pool mobile steam collecting device and a bottom filter system. Background Art
[0002] High-temperature liquid slag is the main by-product of blast furnace smelting, with extremely high solid waste resource recycling value and economic benefits. At present, the mainstream slag treatment method in domestic and foreign steel enterprises is the water slagging process. High-speed water flow is used to break and quench the molten slag into a loose slag-water mixture (hereinafter referred to as water slag), which flows into the filter pool through the slag flushing channel. The liquid water is filtered through the filter layer in the filter pool, leaving solid and wet slag particles on the top of the filter material, and then the slag particles are grabbed by a bridge grab crane and transported out by a vehicle or a belt.
[0003] The liquid molten slag has a relatively high temperature (1350°C - 1500°C). A large amount of molten slag continuously undergoes intense heat transfer during the water quenching granulation process, generating a large amount of steam. Especially in winter, the environmental temperature is low and the environmental temperature difference is large, resulting in more steam generation. To avoid the escape and direct emission of the generated steam, a steam collecting device is set on the top of the filter pool. However, during the slag-grabbing process, the slag particles in the grab bucket will spill, and the slag accumulation on the top of the steam collecting device is relatively serious, the equipment structure is easily damaged, and the steam cannot be effectively collected.
[0004] Specifically, as Figure 1 shown, the bottom filter pool includes a first pool body 41 and a second pool body 42 arranged left and right. The bottom filter pool further includes a mobile steam collecting cover 4, which can move left and right on the first pool body 41 and the second pool body 42. A slag particle collecting hopper 43 is arranged outside the right side of the second pool body 42. During the process of the overhead crane grab 5 grabbing the slag particles in the first pool body 41 and transporting them into the slag particle collecting hopper 43, the slag particles in the overhead crane grab 5 will spill onto the mobile steam collecting cover 4 on the second pool body 42. After long-term operation, the slag accumulation on the top of the mobile steam collecting cover 4 is relatively serious and it is easily crushed. Content of the Utility Model

[0033] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0034] For the convenience of understanding and description, the following description of the present invention adopts an absolute positional relationship. Without special instructions, the orientation word "up" herein represents Figure 8 the upper side direction in Figure 8 the lower side direction in Figure 8 the left side direction in Figure 8 the right side direction in Figure 8 the front direction represents the direction perpendicular to Figure 8 the paper surface and pointing to the inner side of the paper surface, and the orientation word "rear" represents the direction perpendicular to
[0035] and pointing to the outer side of the paper surface. The present invention is described from the observation perspective of the reader or user, but the above orientation words should not be understood or interpreted as limiting the protection scope of the present invention. Regarding the dimensions and angles of the components therein, those skilled in the art can specifically determine according to actual needs.
[0035] As Figures 2 to 8 shown, a self-weight slag-discharging bottom filtration tank movable steam collection device according to an embodiment of the present invention includes a support frame 1, a top cover 3 and a driving mechanism 2. The top cover 3 contains a plurality of cover areas 31 arranged in the front-rear direction, and each cover area 31 contains a plurality of self-weight discharging flaps 32 arranged in the left-right direction. The self-weight discharging flaps 32 are connected to the support frame 1 through a rotating shaft 33. The rotating shaft 33 is in a horizontal state, and the self-weight discharging flaps 32 can rotate around the rotating shaft 33. The driving mechanism 2 can drive the support frame 1 and the top cover 3 to move in the left-right direction or the front-rear direction.
[0036] As Figure 9 shown, the self-weight unloading type bottom filter pool mobile steam collection device includes a plurality of self-weight unloading type flap plates 32. After the slag particles 6 fall on the self-weight unloading type flap plates 32, the slag particles 6 can cause the self-weight unloading type flap plates 32 to rotate, and the slag particles 6 can fall into the bottom filter pool, which can not only avoid the situation that the self-weight unloading type bottom filter pool mobile steam collection device is easily crushed by accumulated slag, but also improve the operation environment in the blast furnace slag area, providing equipment guarantee for realizing a green factory.
[0037] The support frame 1 can select a steel structure beam that meets the size according to the size of a single filter pool body. The support frame 1 includes a bottom frame 11. The bottom frame 11 has a rectangular structure. The bottom frame 11 includes cross beams 12 and longitudinal beams 13. The cross beams 12 extend in the left-right direction, and the longitudinal beams 13 extend in the front-back direction. The two longitudinal beams 13 are arranged parallel to each other at intervals in the left-right direction. A plurality of cross beams 12 are located between the two longitudinal beams 13. The plurality of cross beams 12 are arranged at intervals in the front-back direction. The left and right ends of each cross beam 12 are fixedly connected to the corresponding two longitudinal beams 13. A cover installation area 14 is formed between two adjacent cross beams 12.
[0038] As Figures 2 to 5 shown, the cover areas 31 and the cover installation areas 14 correspond one by one. For example, both the cover areas 31 and the cover installation areas 14 include 7. An installation cross bar 15 is arranged above the cross beam 12. The installation cross bar 15 extends in the left-right direction. The installation cross bar 15 is arranged parallel to the cross beam 12 up and down. The installation cross bar 15 is fixedly connected to the cross beam 12 through installation columns 16. The plurality of installation columns 16 are arranged at intervals in the left-right direction.
[0039] A plurality of bearing seats 17 are arranged on each installation cross bar 15. The plurality of bearing seats 17 are arranged at intervals in the left-right direction. Each cover area 31 includes a plurality of rotating shafts 33. In each cover area 31, the self-weight unloading type flap plates 32 and the rotating shafts 33 are connected in a one-to-one correspondence. Each self-weight unloading type flap plate 32 can be disassembled separately. The rotating shaft 33 extends in the front-back direction. The end of the rotating shaft 33 is connected to the bearing seat 17 through a bearing 34.
[0040] To ensure that the steam collection device can be used for a long time and has structural stability in the slag environment, the self-weight unloading type flap plate 32 is preferably made of a material that is acid-resistant, alkali-resistant, and high-temperature resistant (such as 100 °C), such as fiberglass. As Figure 6 shown, the self-weight unloading type flap plate 32 is generally in a shape of a pointed roof (or arch bridge). The self-weight unloading type flap plate 32 includes a front side plate 35, a rear side plate 36, a left side plate 37, and a right side plate 38. The front side plate 35 and the rear side plate 36 are arranged at intervals in the front-back direction. The left side plate 37 and the right side plate 38 are located between the front side plate 35 and the rear side plate 36. The left side plate 37 and the right side plate 38 are connected to form an inverted V-shaped structure. The included angle between the left side plate 37 and the right side plate 38 can be 110° - 160°.
[0041] Both the front side plate 35 and the rear side plate 36 are triangular. The front side plate 35 and the rear side plate 36 are symmetric front and back and are mirror images of each other. The front ends of the left side plate 37 and the right side plate 38 are both hermetically connected to match the upper side edge of the front side plate 35. The rear ends of the left side plate 37 and the right side plate 38 are both hermetically connected to match the upper side edge of the rear side plate 36. The upper ends of the left side plate 37 and the right side plate 38 are hermetically connected to match each other.
[0042] The self-gravity discharging type tipping plate 32 is fixedly connected to the rotating shaft 33. The rotating shaft 33 passes through the front side plate 35 and the rear side plate 36 of the self-gravity discharging type tipping plate 32. The tip of the self-gravity discharging type tipping plate 32 faces upward, and the opening of the self-gravity discharging type tipping plate 32 faces downward. The left side plate 37 and the right side plate 38 can be symmetric left and right and are mirror images of each other. Or, in order to make it easier for the self-gravity discharging type tipping plate 32 to rotate after the slag particles 6 fall on the self-gravity discharging type tipping plate 32, the length of the left side plate 37 in the left-right direction can be greater than the length of the right side plate 38.
[0043] In order to make the self-gravity slag discharging type bottom filter pool mobile steam collecting device have better sealing performance, the lower ends of two adjacent self-gravity discharging type tipping plates 32 match each other, and the lower end of the self-gravity discharging type tipping plate 32 matches the cross beam 12 adjacent to it front and back. A sealing strip is arranged at the lower end edge of the self-gravity discharging type tipping plate 32. The sealing strips of two adjacent self-gravity discharging type tipping plates 32 on the left and right can rub against each other, and the sealing strip of one self-gravity discharging type tipping plate 32 can rub against the cross beam 12 of the adjacent bottom frame 11.
[0044] Preferably, the sealing strip can be selected from a sealing brush strip or a sealing felt strip. The sealing brush strip or the sealing felt strip can not only ensure better sealing effect during the rotation of the self-gravity discharging type tipping plate 32, but also avoid excessive frictional resistance caused by using a rubber sealing strip, which is not conducive to the rotation of the self-gravity discharging type tipping plate 32 due to insufficient gravity of the slag particles 6.
[0045] Four wheels and multiple layers of sealing components are connected below the support frame 1. The wheels can be fixedly connected to the support frame 1 through bolts. The driving mechanism 2 can drive the support frame 1 to move in the left-right direction. The multiple layers of sealing components (also called a sealing curtain) are in a rectangular structure. The support frame 1 and the multiple layers of sealing components are connected in an up-and-down matching manner. The multiple layers of sealing components can ensure the hermetic connection between the support frame 1 and the bottom filter pool. Ensure that the steam collecting device can also ensure the sealing effect and service life in the presence of moving errors.
[0046] The driving mechanism 2 can adopt an existing motor. The driving mechanism 2 can drive the wheels to rotate. The driving mechanism 2 is fixedly connected to the support frame 1. To ensure the stability and smoothness of the equipment during translation, the motors are preferably arranged on the opposite sides, and two motors are appropriate. The installation position is above the support frame 1 of the steam collecting device.
[0047] The following introduces a bottom filtration system. As Figures 7 to 8 shown, the bottom filtration system includes a first tank body 41 and a second tank body 42 arranged left and right. The bottom filtration system further includes the above-mentioned self-weight slag-discharging type bottom filtration tank mobile steam collection device and a slag particle collection hopper 43. The slag particle collection hopper 43 is located directly to the right of the second tank body 42. The self-weight slag-discharging type bottom filtration tank mobile steam collection device is located on the first tank body 41 and the second tank body 42. Rails are provided on the first tank body 41 and the second tank body 42, and the rails can be used for the self-weight slag-discharging type bottom filtration tank mobile steam collection device to move left and right on the first tank body 41 and the second tank body 42. The self-weight slag-discharging type bottom filtration tank mobile steam collection device can seal the upper end of the first tank body 41 or the upper end of the second tank body 42.
[0048] The following introduces the working process of the bottom filtration system and the self-weight slag-discharging type bottom filtration system mobile steam collection device.
[0049] Step 1: The blast furnace water slagging system issues an interlock control instruction, and the driving mechanism 2 works. The self-weight slag-discharging type bottom filtration tank mobile steam collection device moves to the second tank body 42 to the right, and the self-weight slag-discharging type bottom filtration tank mobile steam collection device seals the upper end of the second tank body 42, and the driving mechanism 2 stops working. After the self-weight slag-discharging type bottom filtration tank mobile steam collection device stops, a stop-in-place instruction is issued, and at the same time, the control system turns on the slagging signal. The slagging water electric valve and the slagging channel valve are opened, and the slag-water mixture enters the second tank body 42. After the slagging command for the second tank body 42 is issued, the first tank body 41 synchronously starts the slag-grabbing process, that is, the overhead crane grab 5 grabs the slag particles in the first tank body 41 and transports them into the slag particle collection hopper 43, and then transports them away by belt or truck to realize the external transportation of slag particles. After the slag particles 6 scattered by the overhead crane grab 5 fall on any one of the self-weight discharging type flap plates 32, the slag particles 6 can rotate the self-weight discharging type flap plate 32 by relying on their own gravity and impact force. After the self-weight discharging type flap plate 32 rotates, the slag particles 6 on the self-weight discharging type flap plate 32 can fall into the second tank body 42.
[0050] Or, after the slag particles 6 scattered by the overhead crane grab 5 fall on any one of the self-weight discharging type flap plates 32, the slag particles 6 move along the inclined direction of the left side plate 37 or the right side plate 38 and slide to the junction of two adjacent self-weight discharging type flap plates 32. When the amount of scattered slag particles 6 collected is large enough, a large pressure will be generated, and two adjacent self-weight discharging type flap plates 32 will deflect to generate a gap, so that the collected slag particles 6 fall into the second tank body 42, realizing the automatic slag-discharging function of the steam collection device and also avoiding the possibility of damage to the device structure. At the same time, the self-weight discharging type flap plates 32 that are independent of each other in pairs also provide a solid guarantee for the rapid maintenance of the steam collection device.
[0051] In addition, anti-collision steel columns can be added to prevent the grab bucket of the crane from colliding with the steam collection device and causing damage due to manual operation errors or automation failures of the slag-grabbing crane.
[0052] Step 2: The blast furnace water slagging system issues an interlock control instruction to drive the driving mechanism 2 to work. The self-weight slag-discharging bottom filter tank mobile steam collection device moves to the upper part of the first tank body 41 to the left. The self-weight slag-discharging bottom filter tank mobile steam collection device closes the upper end of the first tank body 41, and the driving mechanism 2 stops working. After the self-weight slag-discharging bottom filter tank mobile steam collection device stops, a stop-in-place instruction is issued, and at the same time, the control system turns on the slagging signal. The slag water mixture enters the first tank body 41 by opening the slagging water electric valve and the slag ditch valve. After the slagging command for the first tank body 41 is issued, the second tank body 42 synchronously starts the slag-grabbing process, that is, the overhead crane grab bucket 5 grabs the slag particles in the second tank body 42 and transports them into the slag particle collection hopper 43, and then transports them away by belt or vehicle to realize the external transportation of slag particles.
[0053] Step 3: The above steps 1 and 2 can be repeated successively as needed to achieve continuous operation. Observing the water level height information in the first tank body 41 and the second tank body 42 is the key to switching the working filter tank and the systematic process control. To ensure that the water level height in the filter tank is lower than the filter tank wall during the water slagging process, scanning devices or camera equipment can be added to the self-weight slag-discharging bottom filter tank mobile steam collection device, the first tank body 41, and the second tank body 42 to dynamically measure the water level height in the first tank body 41 and the second tank body 42 in real time during the slagging process.
[0054] The above are only specific embodiments of the present invention and cannot limit the scope of implementation of the invention. Therefore, the replacement of equivalent components or equivalent changes and modifications made according to the protection scope of the present invention should still fall within the scope covered by the present invention. In addition, the technical features in the present invention can be freely combined with each other between technical features, between technical features and technical solutions, and between technical solutions.
