Detailed Implementation
[0022] To facilitate understanding of the technical solution of the present invention, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.
[0023] Example 1 like Figure 1-4 As shown, a mud-dissolving device for producing fluidized solidified soil to replace shield tunneling synchronous mortar includes a main body 1, a support body 2, a circulating flushing structure 3, a mud-dissolving structure 4, a vibration structure 5, and a filtration structure 6. The main body 1 is mounted on the support body 2 and includes a front main body 1-1, a rear main body 1-2 and a lower main body 1-3. The front main body 1-1 is connected to the rear main body 1-2, and the lower main body 1-3 is located between the front main body 1-1 and the rear main body 1-2. The upper end of the front main body 1-1 is a solidified soil inlet 1-1-1 for the entry of solidified soil.
[0024] The circulating flushing structure 3 is mounted on the main body 1. The circulating flushing structure 3 includes a circulating pipe 3-1 located on the side of the main body 1, a pipe nozzle 3-3 located at one end of the circulating pipe 3-1, and a pipe outlet 3-2 located at the lower end of the main body 1. The pipe nozzle 3-3 is located inside the main body 1. In this embodiment, there are multiple pipe nozzles 3-3, respectively located in the front of the main body 1-1 and the rear of the main body 1-2. The number of pipe nozzles 3-3 can be set according to specific needs; only two are shown in the figure for ease of illustration. Water flows from the circulating pipe 3-1 into the pipe nozzle 3-3 and is sprayed into the interior of the main body 1. Finally, the mud mixture flows out from the pipe outlet 3-2.
[0025] The mixing body of the mud-dissolving structure 4 is located inside the main body 1; it is used to mix and stir the solidified soil with the water sprayed from the pipeline nozzle 3-3 to dissolve the solidified soil.
[0026] The vibration structure 5 includes a vibration power source 5-1 disposed on the support body 2 and a vibration actuator 5-2 connected to the vibration power source 5-1; The filter structure 6 includes a first filter screen 6-1 located below the mixing body, a second filter screen 6-2 connected to the vibration actuator 5-2, and a third filter screen 6-3 located below the first and second filter screens 6-1 and 6-2. The vibration of the vibration actuator 5-2 drives the first filter screen 6-1, the second filter screen 6-2, and the third filter screen 6-3 to vibrate, thereby screening the mud mixture after desliming. This allows smaller mud clumps to pass through, while larger mud clumps continue to be deslimed through the desliming structure 4. The shape of the filter holes on the filter screens can be triangular, rectangular, hexagonal, or circular, and can be selected according to requirements.
[0027] In this embodiment, the first filter 6-1 is horizontally or approximately horizontally positioned and is connected between the inner wall of the main body 1 and the vibration actuator 5-2. The second filter 6-2 is vertically or approximately vertically positioned and is connected between the inner wall of the main body 1 and the vibration actuator 5-2. "Approximately horizontal" and "approximately vertical" refer to angles less than or equal to 10 degrees with the horizontal or vertical plane. The first filter screen 6-1, the second filter screen 6-2, and the inner wall of the main body 1 enclose the front main body 1-1. The area between the second filter screen 6-2 and the inner wall of the main body 1 is the rear main body 1-2. The area below the front main body 1-1 and the rear main body 1-2 and above the third filter screen 6-3 is the lower main body 1-3. The area between the lower main body 1-3 and the lower wall of the main body 1 is the guide section 1-4 facing the pipe outlet 3-2. Some small mud clumps will pass through the first filter screen 6-1 and enter the lower main body 1-3. Other small mud clumps will pass through the second filter screen 6-2, enter the rear main body 1-2, and then enter the lower main body 1-3. Finally, they will pass through the third filter screen 6-3 and enter the guide section 1-4.
[0028] like Figure 2As shown, the mud-dissolving structure 4 includes a stirring power source 4-1 mounted on the main body 1. The stirring body includes a stirring shaft 4-2 with one end connected to the stirring power source 4-1 and the other end located inside the main body 1. The stirring shaft 4-2 is equipped with several stirring blades 4-3. The stirring power source 4-1 includes a stirring motor 4-1-1 mounted on the main body 1, drive wheels 4-1-2 connected to one end of the two stirring shafts 4-2, and a transmission belt 4-1-3 sleeved around the output end of the stirring motor 4-1-1 and the two drive wheels 4-1-2. The stirring motor 4-1-1 operates, causing the drive wheels 4-1-2 to rotate via the transmission belt 4-1-3, thereby driving the stirring shaft 4-2 to rotate. The stirring blades 4-3 then stir and dissolve the solidified soil. In practical use, the number of stirring shafts 4-2 can be selected according to the specific quality of the solidified soil. Furthermore, the orientation and rotation direction of the stirring blades 4-3 can also be adjusted as needed; for example, adjacent stirring shafts 4-2 can rotate in the same direction or in opposite directions.
[0029] A buffer mechanism 5-3 is provided between the main body 1 and the support body 2, which can buffer the vibration when the vibration actuator 5-2 is working, preventing the support body 2 and other components on the support body 2 from being damaged by vibration.
[0030] like Figure 3 As shown, the vibration actuator 5-2 includes a drive shaft 5-2-2 located on the drive end of the vibration power source 5-1, an eccentric housing 5-2-1 located on the drive shaft 5-2-2 and connected to the main body 1, and an eccentric block 5-2-3 located on the drive shaft 5-2-2. The uneven texture of the eccentric block 5-2-3 causes its center of gravity to be not on the rotational center of gravity. The rotation of the eccentric block 5-2-3 generates an eccentric force that causes the main body 1 to vibrate through the drive shaft 5-2-2 and the eccentric housing 5-2-1.
[0031] Example 2 The difference between Example 2 and Example 1 is that both the first filter screen 6-1 and the second filter screen 6-2 are connected to the vibration actuator 5-2. That is, one end of the first filter screen 6-1 and the second filter screen 6-2 is only connected to the vibration actuator 5-2 and not to the inner wall of the main body 1. In actual use, although the first filter screen 6-1 and the second filter screen 6-2 are not connected to the inner wall of the main body 1, the distance between the other end of the first filter screen 6-1 and the inner wall of the main body 1 is small, generally between 3-8 mm, to prevent larger mud clumps from entering the lower main body 1-3 through this gap. The vibration actuator 5-2 includes a drive shaft 5-2-2 located on the drive end of the vibration power source 5-1, an eccentric housing 5-2-1 located on the drive shaft 5-2-2, and an eccentric block 5-2-3 located on the drive shaft 5-2-2. The uneven texture of the eccentric block 5-2-3 causes its center of gravity to be not on the rotational center of gravity. The eccentric housing 5-2-1 is provided on the drive shaft 5-2-2. The rotation of the eccentric block 5-2-3 generates an eccentric force that causes the eccentric housing 5-2-1 to vibrate through the drive shaft 5-2-2. The vibration of the eccentric housing 5-2-1 drives the first filter screen 6-1 and the second filter screen 6-2 to vibrate.
[0032] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention shall be determined by the scope defined in the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be considered as within the scope of protection of the present invention.
