[0029] Example 1

[0030] Reference Figure 1 A schematic diagram of the overall structure of a slag-water separation and recovery device for steel production is provided, as shown below. Figure 1-4A slag-water separation and recycling device for steel production includes a slag-water separation box mechanism 100, comprising a slag-water separation box assembly 101 and a dredging support assembly 102 fixedly installed inside the slag-water separation box assembly 101, the dredging support assembly 102 dividing the interior of the slag-water separation box assembly 101 into an upper half-section M and a lower half-section N; a filtration mechanism 200, comprising a filter plate assembly 201 slidably embedded inside the upper half-section M and a spring 202 fixedly connected to the bottom of the filter plate assembly 201; both the upper and lower ends are fixedly installed via bearings. The cleaning mechanism 300 inside the upper half zone M includes a cleaning component 301 and a driven component 302 fixedly installed on the upper side of the cleaning component 301; and a drive mechanism 400, including a support frame assembly 401 fixedly installed inside the upper half zone M and a drive component 402 fixedly installed inside the support frame assembly 401 by bearings; the cleaning component 301 can be limited and embedded in the filter plate assembly 201, the drive component 402 and the driven component 302 mesh with each other, and the drive component 402 can be driven by the water flow entering the upper half zone M;

[0031] In this process, wastewater is introduced into the upper section M of the slag-water separation tank assembly 101. After the wastewater is filtered by the filter plate assembly 201, the solid steel slag is separated. The liquid passes through the filter plate assembly 201 and is discharged from the slag-water separation tank assembly 101. As the accumulated solid steel slag gradually increases, the filter plate assembly 201 descends, compressing the spring 202. During the descent of the filter plate assembly 201, the unblocking support assembly 102 provides support and unblocks the filter plate assembly 201, allowing water to flow through and be discharged. When the accumulated solid steel slag reaches a certain amount, the filter plate assembly 201 descends to a designated position. When the water entering the upper half of zone M is in place, it drives the drive component 402 to work. The support frame component 401 supports the drive component 402. The operation of the drive component 402 causes the driven component 302 to drive the cleaning component 301 to rotate. The rotation of the cleaning component 301 sweeps away the solid steel slag on the surface of the filter plate component 201. After the cleaning component 301 rotates once, the solid steel slag is discharged into the lower half of zone N. At this time, the filter plate component 201 is no longer compressed. The spring 202 resets and pushes the filter plate component 201 to rise, thereby fixing the position of the cleaning component 301 and waiting for the next cycle.

[0032] Furthermore, the slag-water separation box assembly 101 includes a slag-water separation box body 101a, with an inlet pipe 101b fixedly connected to the upper end of the slag-water separation box body 101a, and a drain pipe 101c fixedly connected to one side of the slag-water separation box body 101a; the inlet pipe 101b is connected to the position inside the upper half of the M near the support frame assembly 401, and the drain pipe 101c is connected to the position inside the upper half of the M near the unblocking support assembly 102.

[0033] Furthermore, the unblocking support assembly 102 includes a fan-shaped support base plate 102a, a side baffle plate 102b is fixedly connected to the edge of the fan-shaped support base plate 102a, and a plurality of unblocking rods 102c are fixedly connected to the upper side of the fan-shaped support base plate 102a; the filter plate assembly 201 includes a filter plate 201a, and a plurality of filter holes 201b are provided on the filter plate 201a.

[0034] Furthermore, the spring 202 is fixedly connected to the bottom of the filter plate 201a. The bottom of the spring 202 is supported by the fan-shaped support base plate 102a. The filter plate 201a is slidably embedded in the interior of the upper half region M. The number and position of the filter holes 201b correspond to the unblocking rod 102c. The unblocking rod 102c can penetrate the filter holes 201b. The diameter of the unblocking rod 102c is smaller than the aperture of the filter holes 201b.

[0035] Operating procedure: Wastewater is introduced into the upper half of zone M through inlet pipe 101b. Solid steel slag in the wastewater is blocked by filter plate 201a. Liquid flows through several filter holes 201b into the space between filter plate 201a and fan-shaped support base plate 102a. The side baffle plate 102b prevents the liquid from entering the lower half of zone N. The liquid can then be discharged through drain pipe 101c. When some solid steel slag blocks several filter holes 201b, the filter plate 201a will be affected by the accumulation on the upper side. As the water level rises, the filter plate 201a descends, causing the spring 202 to be compressed onto the fan-shaped support base plate 102a. At this time, the descent of the filter plate 201a causes several unblocking rods 102c to unblock several filter holes 201b. After unblocking, the filter holes 201b can quickly guide the water, thus allowing the water accumulated on the upper side of the filter plate 201a to be directed to the lower side. The surface of the filter plate 201a becomes lighter, causing the spring 202 to return to its original position. The return of the spring 202 causes the filter plate 201a to rise.

[0036] Example 2

[0037] Reference Figure 1-5 This embodiment differs from the first embodiment in that: a V-shaped groove 201c is also provided on the upper side of the edge of the filter plate 201a, and a downwardly inclined V-shaped guide plate 201d is fixedly connected to the edge of the filter plate 201a; the cleaning assembly 301 includes a support column 301a, and a V-shaped cleaning frame 301b is fixedly connected to the upper end of the outer side of the support column 301a.

[0038] Furthermore, the bottom of the support column 301a is fixedly mounted on the fan-shaped support base plate 102a via a bearing, the V-shaped sweeping frame 301b can be limited and embedded in the V-shaped slot 201c, and the upper side of the support column 301a is also fixedly connected to the driven component 302.

[0039] The rest of the structure is the same as in Example 1.

[0040] Operation process: When the filter plate 201a descends to a depth exceeding the V-shaped groove 201c on the filter plate 201a, the upper end of the unblocking rod 102c and the inlet of the filter hole 201b are parallel to each other. The blocked solid steel slag is just pushed out of the filter hole 201b. At the same time, the V-shaped cleaning frame 301b disengages from the V-shaped groove 201c. Through the drive mechanism 400 and the driven component 302, the support column 301a is driven to rotate. The rotation of the support column 301a causes the V-shaped cleaning frame 301b to rotate. The rotation of the V-shaped cleaning frame 301b causes the solid steel slag located on the filter plate 201a and the filter hole 201b to rotate. The unblocking rod 102c lifts up the solid steel slag located above the filter hole 201b, which is then swept away. After the V-shaped cleaning frame 301b rotates once, the solid steel slag falls into the lower half of the N region under the guidance of the V-shaped guide plate 201d. The liquid can then flow back into the lower side of the filter plate 201a through the filter hole 201b. At the same time, the surface of the filter plate 201a becomes lighter, causing the spring 202 to reset. The reset of the spring 202 causes the filter plate 201a to rise. The rise of the filter plate 201a causes the V-shaped cleaning frame 301b to re-enter the V-shaped slot 201c, thus restricting its rotation.

[0041] Example 3

[0042] Reference Figure 1-6 This embodiment differs from the above embodiments in that: the driven component 302 includes a second support column 302a, and a first bevel gear 302b is fixedly connected to the outer side of the second support column 302a; the upper end of the second support column 302a is fixedly installed on the top inner wall of the slag-water separation tank body 101a through a bearing, and the first bevel gear 302b and the drive component 402 mesh with each other.

[0043] Furthermore, the support frame assembly 401 includes a flow guide outer plate 401a, an inlet 401b is provided on the flow guide outer plate 401a, an outlet 401c is provided at the bottom of the flow guide outer plate 401a, and a T-shaped support fixing plate 401d is fixedly connected to the upper side of the flow guide outer plate 401a.

[0044] Furthermore, the outer guide plate 401a is fixedly installed on the top inner wall of the slag-water separation box body 101a by a T-shaped support fixing plate 401d, the lower ends of the water inlet 401b and the water inlet pipe 101b are close to each other, and the drive assembly 402 is fixedly installed inside the outer guide plate 401a by a bearing.

[0045] Furthermore, the drive assembly 402 includes an impeller 402a, a rotating shaft 402b fixedly connected to the middle of the impeller 402a, a bevel gear 402c fixedly connected to one end of the rotating shaft 402b, and the other end of the rotating shaft 402b fixedly mounted to the middle position of the guide plate 401a via a bearing; the bevel gear 402c and the bevel gear 302b mesh with each other.

[0046] The rest of the structure is the same as in Example 2.

[0047] Operation process: When the V-shaped cleaning frame 301b disengages from the V-shaped slot 201c, the water flowing in through the water inlet pipe 101b passes through the water inlet 401b and hits the impeller 402a, causing the impeller 402a to rotate. The rotation of the impeller 402a causes the rotating shaft 402b to drive the second bevel gear 402c to rotate. The rotation of the second bevel gear 402c causes the meshing first bevel gear 302b to rotate. The rotation of the first bevel gear 302b causes the second support column 302a and the first support column 301a to rotate. The rotation of the first support column 301a causes the V-shaped cleaning frame 301b to rotate. The rotation of the V-shaped cleaning frame 301b causes the solid steel slag on the surface of the filter plate 201a to be cleaned.
