[0042] Read in detail Figure 4 and Figure 5As shown, a slide groove 202a is vertically provided on the upper edge of the vertical arm of the L-shaped frame 202, a longitudinal rod 204 is welded to the top of the vertical arm of the L-shaped frame 202, and a mounting rod 205 is welded to the front and rear ends of the top of the longitudinal rod 204, the top of the mounting rod 205 movably passes through the top of the flash tank 100 and is welded to the lower surface of the U-shaped plate 206, and a movable plate 207 is slidably sleeved on the outer wall of the mounting rod 205.

[0044] Read in detail Figure 4 and Figure 5 As shown, a connecting rod 203a is welded on one side of the front and rear end surfaces of the adjustment plate 203, and the free end of the connecting rod 203a is rotatably connected to the inside of the lifting block 207b. A through groove 202b is opened in the horizontal direction on the horizontal support arm of the L-shaped frame 202, and a connecting rod 203b is welded on the other side of the front and rear end surfaces of the adjustment plate 203, and the free end of the connecting rod 203b is movably connected to the inside of the through groove 202b.

[0045] Read in detail Figure 7 and Fig. 9 As shown, the water inlet end of the water pump 301 is fixedly connected to the water suction pipe 302, the end of the water suction pipe 302 away from the water pump 301 is fixedly connected to the bottom of the water suction cover 303, the water outlet end of the water pump 301 is fixedly connected to the connecting pipe 304, the end of the connecting pipe 304 away from the water pump 301 is fixedly connected to the telescopic hose 306, the end of the telescopic hose 306 away from the connecting pipe 304 passes through the longitudinal rod 204 and is fixedly connected to one end of the spray pipe 307, and the end of the spray pipe 307 away from the longitudinal rod 204 is fixedly connected to multiple high-pressure nozzles 307b at equal intervals along the longitudinal direction.

[0046] When the above arrangement is in use, the sleeve rod 206a is rotated, and the sleeve rod 206a drives the mounting rod 207c to rise and fall while rotating, and applies external force to the movable plate 207 through the mounting rod 207c, so that the movable plate 207 applies external force to the lifting block 207b through the mounting rod 1 205, and the lifting block 207b drives the adjustment plate 203 to move through the connecting rod 1 203a, thereby adjusting the inclination angle of the adjustment plate 203, and then starts the water pump 1 301, so that the slag water in the flash tank 100 enters the spray pipe 307 through the water pumping hood 303, the water pumping pipe 302, the connecting pipe 1 304 and the telescopic hose 306 in turn, and sprays the slag water on the adjustment plate 203 through the high-pressure nozzle 307b, thereby increasing the evaporation area of ​​the slag water and further improving the flash evaporation efficiency of the slag water.

[0047] Furthermore, a mounting ring 307a is welded to the front and rear ends of one side of the longitudinal rod 204, and the front and rear ends of the spray pipe 307 are sleeved on the inner side of the mounting ring 307a. Example 2

[0048] Reference Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, except that, in order to facilitate the adjustment of the distance between the liquid level in the flash tank 100 and the adjustment plate 203, it is avoided that the water on the adjustment plate 203 will stir up large splashes when flowing back.

[0049] Specifically, a U-shaped frame 208 is welded on the rear end face of the flash tank 100, and the bottom of the horizontal arm of the U-shaped frame 208 is fixedly connected to the drive motor 208b through the motor frame 208a. The output shaft of the drive motor 208b is fixedly connected to the threaded rod 208c, and the outer wall of the threaded rod 208c is threadedly sleeved with an L-shaped rod 209. The top of the longitudinal arm of the L-shaped rod 209 is welded to the lower surface of the horizontal arm of the U-shaped plate 206.

[0050] When the above arrangement is in use, the drive motor 208b is started, and the output shaft of the drive motor 208b drives the threaded rod 208c to rotate synchronously. Under the action of the threaded screw connection between the threaded rod 208c and the L-shaped rod 209, the L-shaped rod 209 applies an external force to the U-shaped plate 206, so that the U-shaped plate 206 is lifted and lowered vertically. The U-shaped plate 206 drives the longitudinal rod 204 and the L-shaped frame 202 to be lifted and lowered through the mounting rod 1 205, thereby adjusting the distance between the adjustment plate 203 and the liquid level inside the flash tank 100.

[0051] Furthermore, the vertical arms on both sides of the U-shaped frame 208 are vertically provided with a second slide groove 208d, and the vertical arms of the L-shaped rod 209 are symmetrically fixed with a slider 1 209a on both sides, and the free end of the slider 1 209a is movably connected to the inside of the second slide groove 208d.

[0054] When the above arrangement is in use, the filter screen 303a is used to prevent solid particles such as carbon slag in the slag water from entering the structures such as the water extraction hood 303. At the same time, after the equipment has been running for a period of time, the solenoid valve 304a is closed and the solenoid valve 303c is started, so that the water in the connecting pipe 304 enters the backwash pipe 303b through the three-way joint 305, and flows back to the water extraction hood 303 through the backwash pipe 303b, thereby realizing the backwashing of the filter screen 303a in the water extraction hood 303, thereby preventing the filter screen 303a from being blocked.

Example 5

[0061] Reference Figure 1 , Figure 2 , Figure 3 and Fig.14 , which is the fifth embodiment of the present invention, is based on any of the above embodiments, except that this embodiment is proposed to facilitate sampling and testing of the slag water after flash evaporation in the flash tank 100.

[0062] Specifically, it includes a sampling assembly 600 disposed below the rear end surface of the flash tank 100 , and the sampling assembly 600 includes a mounting frame 601 , a floating block 602 , a sampling tube 603 and a sampling box 604 .

[0063] Read in detail Fig.14 , Fig.15 and Fig.17 The mounting frame 601 is provided with two groups and is respectively fixedly connected to the two sides of the rear end surface of the flash tank 100 in the vertical direction. The floating block 602 is movably connected between the mounting frames 601 in the vertical direction. The bottom front end of the floating block 602 is fixedly connected with a collar 602a. The sampling tube 603 is sleeved inside the collar 602a. One end of the sampling tube 603 is fixedly connected with a sampling cover 603c. A sampling cavity 604a is provided at the lower part of the sampling box 604. The sampling cavity 604a is further provided with detection components such as a water temperature sensor and a liquid concentration sensor. The sampling box 604 is provided with a regulating chamber 604b on the upper part thereof, and a grey water pump 603a is fixedly connected to the lower part of the rear end surface of the sampling box 604. The water inlet end of the grey water pump 603a is fixedly connected to the other end of the sampling tube 603, and the water outlet end of the grey water pump 603a is fixedly connected to a connecting pipe 603b. The end of the connecting pipe 603b away from the grey water pump 603a passes through the bottom of the sampling box 604 and extends to the interior of the sampling chamber 604a.

[0064] When the above arrangement is in use, the gray water pump 603a is started. Under the action of the gray water pump 603a, the slag water in the flash tank 100 enters the sampling chamber 604a through the sampling cover 603c and the sampling tube 603 in turn. The slag water is detected by the water temperature sensor, liquid concentration sensor and other detection components in the sampling chamber 604a. When the slag water meets the standards, the slag water that meets the standards is directly discharged into the flocculation sedimentation tank for sedimentation and slag removal, and the slag water that does not meet the standards is discharged into the next-level flash tank 100 for flash evaporation again until the slag water meets the flocculation sedimentation standards.

[0065] Furthermore, fixing rods 604 c are welded around the front end surface of the sampling box 604 , and one end of the fixing rod 604 c away from the sampling box 604 is welded below the rear end surface of the flash tank 100 .

[0067] Reference Fig.15 , which is the sixth embodiment of the present invention, is based on the previous embodiment, except that, in order to facilitate sampling of slag water at different depths in the flash tank 100, the structure of the floating block 602 is refined.

[0068] Specifically, the outer walls of the mounting frame 601 that are close to each other are vertically provided with slide grooves 601a, and the interior of the slide grooves 601a is movably connected with sliders 602b. The ends of the sliders 602b located on the outside of the slide grooves 601a are respectively fixedly connected to the outer walls on both sides of the floating block 602. The floating block 602 is a hollow structure filled with gas. The interior of the regulating chamber 604b is fixedly connected to a vacuum pump 602c, and the output end of the vacuum pump 602c is fixedly connected to a gas pipe 602d, and the end of the gas pipe 602d away from the vacuum pump 602c is fixedly connected to the bottom of the floating block 602.

[0069] When the above arrangement is in use, the vacuum pump 602c is started, and under the action of the vacuum pump 602c, the gas in the adjustment chamber 604b enters the interior of the float 602. By adding or reducing gas into the float 602, the buoyancy of the float 602 is changed, thereby adjusting the depth of the float 602 in the flash tank 100, thereby facilitating the sampling of slag water at different depths in the flash tank 100.
