DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1-3 As shown, a simple sedimentation device for boiler ash water comprises a tank body 1, with a water inlet 101 and a drain outlet 102 respectively provided on the left and right sides of the tank body 1, and a connecting frame 3 and a limit frame 2 respectively installed on the left and right ends of the front and rear sides of the tank body 1 by bolts, and a plurality of mounting holes 301 are linearly opened on the left side of the connecting frame 3 from top to bottom, and two limit blocks 6 are symmetrically arranged in the mounting hole 301, and the two limit blocks 6 are connected to the mounting hole 301 by sliding grooves and sliders to slide back and forth, and a right-angled triangle protrusion is integrally formed on the end of the limit block 6 away from the mounting hole 301, and a rotating shaft 4 is rotatably connected to the mounting hole 301 through a bearing, and the rotating shaft 4 is threadedly connected to the two limit blocks 6, and the displacement directions of the two limit blocks 6 are always opposite. When the rotating shaft 4 rotates clockwise, the two limit blocks 6 are rotated in opposite directions. The limit blocks 6 are close to each other, and when the rotating shaft 4 rotates counterclockwise, the two limit blocks 6 move away from each other. The displacement directions of the two limit blocks 6 are always opposite through the threaded arrangement on the rotating shaft 4, which belongs to the prior art and will not be described in detail here. The end of the rotating shaft 4 away from the pool body 1 extends out of the connecting frame 3 and is equipped with a turntable 5. A plurality of through holes 202 for plugging in the limit blocks 6 are linearly opened on the left side of the limit frame 2 from top to bottom. A plugging groove 201 connected to the through hole 202 is opened on the side of the limit frame 2. The rotating shaft 4 can be plugged into the plugging groove 201. The side of the connecting frame 3 away from the pool body 1 is equipped with a mounting bracket 5 by bolts. A worm 14 is rotatably connected to the mounting bracket 5 through a bearing. The worm 14 and the worm wheel 13 are meshed with each other. The upper end of the worm 14 passes through the upper side of the mounting bracket 5 and is connected to a handwheel 15.

[0020] A mud discharge assembly for cleaning sediment is provided on the front side of the tank body 1.

[0021] During use, the staff connects multiple tank bodies 1 together according to actual needs, and then the boiler ash flushing water enters the tank body 1 through the water inlet 101 for sedimentation. After the sedimentation is completed, the ash flushing water entering the tank body 1 enters the next tank body 1 through the drain port for the next level of sedimentation. In this technical solution, the flow of the ash flushing water in the tank body 1 only relies on the power when the boiler ash flushing water is discharged, and no other auxiliary power mechanism is required. After the sedimentation is completed, the staff waits for the water flow in the tank body 1 to evaporate, and then the staff cleans the sediment in the tank body 1 through the mud discharge component, thereby ensuring the subsequent use of the sedimentation device;

[0022] When connecting two adjacent pool bodies 1, the staff pushes the pool body 1 so that the left end of the connecting frame 3 is inserted into the limit frame 2. At this time, the left ends of the two limit blocks 6 pass through the through hole 202 and are located on the left side of the limit frame 2, and the rotating shaft is located in the insertion groove 201. Then the staff drives the worm 14 to rotate by turning the handwheel 15. Under the action of the worm wheel 13 and the worm 14 threads, multiple rotating shafts 4 all rotate synchronously with the worm 14, and under the action of the threads, the two limit blocks 6 on the rotating shaft 4 move toward each other so that the side surfaces of the limit blocks 6 fit the inner wall of the through hole 202. At this time, the right side surface of the right-angled triangle protrusion contacts the left side surface of the limit frame 2, limiting the connecting frame 3, so that the connecting frame 3 cannot be separated from the through hole, thereby ensuring the reliability of the two adjacent pool bodies 1 when connected. At the same time, by turning the handwheel 15 and under the action of the worm wheel 13 and the worm 14, the two pool bodies 1 are quickly connected and disassembled, which improves the convenience of the staff when connecting the pool bodies 1.

[0023] When the sediment in the pool body 1 is cleaned, the staff controls the electric telescopic rod 7 to push the baffle 8 to move downward along the slide rail 9 to close the mud discharge port, thereby preventing the subsequent liquid in the pool body 1 from overflowing.

[0024] In this embodiment, a second sealing gasket 11 is glued to the side of the baffle 8 close to the pool body 1 and fits the front side of the pool body 1. When in use, the second sealing gasket 11 further improves the sealing between the baffle 8 and the pool body 1, ensuring that the liquid in the pool body 1 cannot flow out along the gap between the baffle 8 and the pool body 1.

[0025] In this embodiment, the water inlet 101 and the drain outlet 102 are located on the same horizontal line, and the water inlet 101 and the drain outlet 102 are staggered front to back, and the drain outlet 102 can be inserted into the water inlet 101 of the adjacent tank body 1. When in use, the staggered water inlet 101 and the drain outlet 102 extend the flow path of the boiler ash flushing water in the tank body 1. At the same time, it can ensure the flow of the boiler ash flushing water in the tank body 1 and improve the sedimentation effect.

[0026] In this embodiment, a first sealing gasket 10 in contact with the drain outlet 102 is glued to the inner side of the water inlet 101. When in use, the first sealing gasket 10 improves the sealing between the water inlet 101 and the drain outlet 102, preventing water from flowing out along the gap between the water inlet 101 and the drain outlet 102.

[0027] In this embodiment, an observation port 103 is opened through the front side of the pool body 1, and a transparent protective plate 12 is sealed inside the observation port 103 by sealant. When in use, the staff can observe the water level and sedimentation effect in the pool body 1 through the transparent protective plate 12, which is convenient for the staff to understand the sedimentation degree of the boiler ash flushing water.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
