Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Please refer to fig. 1, which is a schematic structural diagram of the slurry balance shield muck feeding preprocessor provided by the present invention.
For ease of illustration, the outer cover of the apparatus is omitted from the drawings. Therefore, the phenomenon that part of the components are suspended and unsupported exists. But does not affect the understanding of the technical solution.
The slurry balance shield muck feeding pretreatment machine 1 comprises a hopper 2, a screening net 21, a screw conveyer 3, a double-shaft paddle stirrer 4, a water retaining wall 41 and a discharge hopper 5.
The cross section of the hopper 2 is V-shaped, the bottom end of the hopper is simultaneously communicated with the tops of the two spiral conveyors 3, and the top end of the hopper is provided with the screening net 21. One side of the screening net 21 is movably connected with the side edge of the hopper 2 through a pivot. Further, the hopper 2 can be fed with water while injecting water, so that the flowability of the viscous shield muck is increased.
The screw portion of the screw conveyor 3 has a housing, the top of which is open and communicates with the bottom of the hopper 2. The two screw conveyors 3 are parallel to each other and are arranged obliquely. The power part is arranged close to the upper end and drives the screw to convey materials towards the lower end. The tail end of the shell in the conveying direction and one side close to the bottom are provided with a discharge hole.
Two blade shafts of the double-shaft blade mixer 4 are arranged in a shell with an open top surface, and the water retaining wall 41 is arranged outside the shell. The inclination angle of the double-shaft paddle stirrer 4 is consistent with that of the screw conveyer 3. Furthermore, the front end paddle has large installation angle, strong conveying capacity and inferior stirring performance; the rear end paddle has small installation angle, strong stirring capability and inferior conveying capability. The top of the paddle is in a zigzag shape, so that the stirring and scattering of the shield muck are facilitated.
The power part is arranged close to the upper end, drives the spiral to stir and convey materials towards the direction of the upper end, and carries out water sealing on the end of the rotating shaft. The discharge port of the screw conveyor 3 is located above the starting point end in the conveying direction of the twin-screw paddle mixer 4.
The water barrier 41 is raised one-half higher than the housing of the twin-shaft paddle mixer 4 and is further raised to a level near the end of the screw conveyor 3. The horizontal position extends to the other end, and does not exceed the height of the power part. I.e. the highest water level is lower than the power section.
The shell of the double-shaft paddle mixer 4 is provided with a discharge outlet at the tail end of the conveying direction and close to one side of the bottom, and a discharge hopper 5 is arranged below the shell and discharges materials to the vibrating screen.
In specific implementation, shield muck is transported to the hopper 2 through the excavator, and the screening net 21 filters large stones, woven bags, wood blocks and other raw material impurities. When stones or other impurities on the screening net 21 are too much to influence the feeding of the raw materials, the screening net can be overturned for cleaning.
The rotational speed of the screw conveyor 3 is controlled to continuously, orderly and uniformly convey the muck to the double-shaft paddle stirrer 4. And controlling the rotating speed of the screw conveyor 3 according to the viscosity of the shield muck and the stacking height.
The double-shaft paddle stirrer 4 is filled with water in advance, and the muck is fully stirred in the water-filled environment after entering the double-shaft paddle stirrer so as to be dissolved in the water. The double-shaft paddle stirrer 4 guides the stirred slurry into a vibrating screen through the discharge hopper 5 for subsequent processing.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
