DETAILED DESCRIPTION

[0022] 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 described embodiments 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 creative work are within the scope of protection of the present invention. Example

[0023] See also Figure 1-Figure 6 The present invention provides a technical solution: a method for treating solid waste in a water treatment project, which uses a solid waste treatment device in a water treatment project, including a collection box 1, and a storage box 2 located above the collection box 1 for storing fixed waste, and a working mechanism 3 for transporting solid waste and performing solid-liquid separation is arranged between the collection box 1 and the storage box 2. The specific method of using the above-mentioned solid waste treatment device in a water treatment project includes the following steps: S1. Loading: The bending plate 23 is driven to reciprocate in the horizontal direction by the linkage assembly 4, and the solid waste in the storage box 2 is pushed to between the two squeezing plates 37 through the trapezoidal channel 21, thereby completing the loading work of the device; S2, conveying: when the squeezing plates 37 are moved in the direction of arrow C, the fixed waste between the two squeezing plates 37 will be blocked by the push plate 311 and the extension plate 312, so that the fixed waste falls from the other end of the two squeezing plates 37 and slides onto the two crushing rollers 71 through the mesh inclined guide plate 6, completing the conveying of the fixed waste; S3, separation: The two squeezing plates 37 move toward the arrow B side and also move in the opposite direction, squeezing the fixed waste between the two squeezing plates 37, thereby squeezing out the water in the fixed waste, achieving the effect of separating the fixed liquid; S4, crushing: by setting a crushing mechanism 7, the solid waste falling on the two crushing rollers 71 is crushed; The working mechanism 3 includes a mesh cover 31 with an integrated solid on the upper surface of the collecting box 1, and two symmetrically distributed quadrilateral slide grooves 32 are provided on the upper surface of the mesh cover 31, and the quadrilateral slide grooves 32 include a bevel groove 1 321, a transverse groove 1 322, a bevel groove 2 323 and a transverse groove 2 324. The upper surface of the mesh cover 31 is provided with a mounting opening 33 which is respectively interconnected with the transverse groove 1 322 and the transverse groove 2 324, and a bevel stopper 34 extending into the quadrilateral slide groove 32 is provided in the mounting opening 33, and a spring 1 35 is fixedly connected between the bevel stopper 34 and the inner wall of the mounting opening 33.

[0024] The working mechanism 3 also includes a support plate 36 located above the mesh cover plate 31 and driven by an external driving device. Two symmetrically distributed extrusion plates 37 are arranged on the support plate 36. Vertical rods 38 are vertically fixed to the lower surface of the extrusion plate 37, and the lower ends of the two vertical rods 38 are respectively slidably connected in two quadrilateral sliding grooves 32. The surface of the support plate 36 is provided with strip grooves 39 for the vertical rods 38 to slide.

[0025] The external driving device is a cylinder.

[0026] In use, the cylinder is started to drive the support plate 36 to reciprocate in the horizontal direction, and the support plate 36 can drive the extrusion plate 37 to reciprocate in the horizontal direction through the vertical rod 38; In the initial state, the vertical rod 38 is located at the intersection of the inclined groove 1 321 and the transverse groove 1 322. When the support plate 36 and the extrusion plate 37 move in the direction indicated by the arrow B, the vertical rod 38 will slide along the inclined groove 1 321 to the transverse groove 2 324. At this time, the two vertical rods 38 will move in opposite directions along the inclined groove 1 321. The vertical rod 38 can drive the extrusion plate 37 to move accordingly, so that the two extrusion plates 37 move in opposite directions while moving to the side of the arrow B, and squeeze the fixed waste between the two extrusion plates 37, so as to squeeze out the water in the fixed waste, and achieve the effect of separating the fixed liquid; When the vertical rod 38 continuously moves toward the arrow B side along the second transverse groove 324, it will gradually encounter one of the inclined surface blocks 34, and push the inclined surface of the inclined surface block 34 to move the inclined surface block 34 into the installation opening 33, so that the vertical rod 38 smoothly moves into the second inclined surface groove 323, and then, the first spring 35 drives the inclined surface block 34 to enter the second transverse groove 324 again through the rebound force, preventing the vertical rod 38 from retreating into the second transverse groove 324; Then, the support plate 36, the extrusion plate 37 and the vertical rod 38 move in the direction of arrow C, so that the two vertical rods 38 slide along the second inclined groove 323 into the first transverse groove 322. While sliding along the second inclined groove 323, the two vertical rods 38 can drive the two extrusion plates 37 to move in opposite directions, so that the distance between the two extrusion plates 37 increases. When the vertical rod 38 moves along the transverse groove 1 322 in the direction of arrow C, it will gradually hit another inclined surface block 34 and push the inclined surface block 34 to move into the installation opening 33, so that the vertical rod 38 can move smoothly into the inclined surface groove 1 321, and then, the spring 1 35 will drive the inclined surface block 34 to enter the transverse groove 2 324 again through the rebound force, preventing the vertical rod 38 from retreating into the transverse groove 1 322.

[0027] A U-shaped plate 310 is fixedly connected to the side wall of the collection box 1, and one end extends between the two extrusion plates 37. The free end of the U-shaped plate 310 is fixedly connected to a push plate 311 located between the two extrusion plates 37. Extension plates 312 are telescopically inserted on opposite sides of the push plate 311, and a spring 2 313 is fixedly connected between the two extension plates 312. The two extension plates 312 are respectively against the surfaces of the two extrusion plates 37.

[0028] During use, when the squeezing plates 37 move in the direction of arrow C, i.e., toward the side close to the pushing plate 311, the fixed waste between the two squeezing plates 37 will be blocked by the pushing plate 311 and the extending plate 312, so that the fixed waste falls from the other end of the two squeezing plates 37, completing the transportation of the fixed waste.

[0031] During use, when the support plate 36 drives the two racks 43 fixed on one side thereof to move in the direction indicated by the arrow C, the rack 43 can drive the gear 42 meshing with it to rotate accordingly, and the gear 42 can drive the bending plate 23 to move in the direction indicated by the arrow B through the rack 2 44 meshing with it, thereby pushing the solid waste in the storage box 2 through the trapezoidal channel 21 to between the two extrusion plates 37, completing the loading work of the device.

[0032] When the support plate 36 drives the squeezing plate 37 to move toward the side of arrow C, the two squeezing plates 37 will also move in opposite directions to increase the distance between them, thereby facilitating the solid waste to fall between the two squeezing plates 37 .

[0033] A bent U-shaped rod is fixedly connected between the collection box 1 and the storage box 2 . Example

[0034] See also Figure 8-Figure 9 This embodiment further explains Example 2, a partition 5 is fixedly connected inside the collection box 1, and two sides of the partition 5 are respectively a water storage space 51 and a solid storage space 52, and a mesh inclined guide plate 6 is fixedly connected to one side of the mesh cover plate 31.

[0035] The water squeezed out by the two squeezing plates 37 will flow into the water storage space 51 through the support plate 36, the mesh cover plate 31 and the mesh inclined guide plate 6, so that the solid waste falling from one side of the support plate 36 will slide through the mesh inclined guide plate 6 to the two crushing rollers 71, and after being crushed by the crushing rollers 71, it will be collected in the partition 5.

[0036] A crushing mechanism 7 is provided in the solid storage space 52, and the crushing mechanism 7 includes two crushing rollers 71 rotatably connected to the inner wall of the solid storage space 52, and gear two 72 coaxially fixed with the two crushing rollers 71 and meshing with each other; an annular shaft 73 is rotatably connected to the inner wall of the solid storage space 52, a gear three 74 is sleeved on the outer surface of one end of the annular shaft 73, and a ratchet 75 is fixed on the inner wall; an L rod 76 is fixedly connected to the surface of the support plate 36, and one end of the L rod 76 is fixedly connected to a rack three 77 meshing with the gear three 74; an annular sleeve 78 coaxially fixed with one of the crushing rollers 71 is provided in the solid storage space 52, a telescopic rod 79 is vertically fixed on the surface of the annular sleeve 78, a ratchet 710 meshing with the ratchet 75 is fixedly connected to the upper end of the telescopic rod 79, and a spring three 711 sleeved on the telescopic rod 79 is fixedly connected between the ratchet 710 and the annular sleeve 78.

[0037] In use, the support plate 36 can drive the rack 3 77 to reciprocate along the horizontal direction through the L rod 76, and the rack 3 77 can drive the gear 3 74 meshing with it to reciprocate, and the gear 3 74 can drive the ratchet 75 coaxially fixed thereto to reciprocate, and the ratchet 75 can drive the annular sleeve 78 and the crushing roller 71 coaxially fixed thereto to rotate in one direction through the ratchet teeth 710 and the telescopic rod 79; The outer sides of the two crushing rollers 71 are each provided with a coaxially fixed gear 72 therewith, and the two gears 72 are meshed with each other, so that the two crushing rollers 71 can rotate in opposite directions to crush the solid waste.
