[0037] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] like Figure 1~Figure 4 As shown, this embodiment proposes a sludge quantitative and shaped feeding system, including a frame 1, a crushing roller 2, the crushing roller 2 includes two and is rotatably set on the frame 1, the crushing roller 2 has a crushing tooth 201, and the crushing teeth 201 of the two crushing rollers 2 are meshed, a filter cloth 3, the filter cloth 3 is movably set on the frame 1 and is located below the crushing roller 2, a material guide trough 4, the material guide trough 4 is set on the frame 1, the material guide trough 4 is in contact with the filter cloth 3, and is located below the crushing roller 2, and a uniform distribution plate 5, the uniform distribution plate 5 is lifted and set on the frame 1, the uniform distribution plate 5 is located in the material guide trough 4 and forms a uniform distribution space 501 between the uniform distribution plate 5 and the filter cloth 3.

[0039] The present embodiment designs a crushing roller 2. When the material enters between the crushing rollers 2, the crushing teeth 201 crush the larger lumps inside the material to facilitate the subsequent processing of the material. Since the speed of the crushing roller 2 is adjustable, the tooth spacing of the two groups of crushing teeth 201 of the two crushing rollers 2 can be adjusted by adjusting the spacing of the crushing rollers 2. Therefore, the feeding amount of the crushing roller 2 to the filter cloth 3 can be adjusted by adjusting the position and speed of the crushing roller 2. When the speed of the crushing roller 2 and the spacing between the two crushing rollers 2 are fixed, quantitative feeding of the material can be achieved. Compared with the prior art, the spiral feeding equipment can only be used for feeding materials with a moisture content of less than 60% when the feeding effect is better. The crushing roller 2 is used to feed the filter cloth 3, which is convenient for maintenance and has a better crushing effect, and meets the quantitative feeding of materials below 75%. After the material falls on the filter cloth 3, the material moves into the guide trough 4 with the movement of the filter cloth 3, and the material is fixed in width through the guide trough 4. After the guide trough 4 fixes the width of the material, the material passes through the uniform distribution space 501 formed by the filter cloth 3 and the uniform distribution plate 5, and the material is initially fixed in height under the action of the uniform distribution plate 5. Through the combination of the crushing roller 2, the filter cloth 3, the guide trough 4 and the uniform distribution plate 5, a large amount of material can be quickly processed, so that the overall shaping effect of the equipment is better. Compared with the prior art, quantitative feeding of materials with a moisture content of less than 75% can be achieved, the feeding range is wider, it is convenient for maintenance, and the shaping effect is better.

[0040] Furthermore, the material guiding trough 4 has a convergent section 401 and a constant-width section 402 , the convergent section 401 is connected to the constant-width section 402 , and the convergent section 401 gradually narrows toward the constant-width section 402 .

[0041] In this embodiment, the material guide trough 4 is designed to be composed of two parts: a convergence section 401 and a constant width section 402, wherein the convergence section 401 gradually narrows toward the constant width section 402 until it is equal to the width of the constant width section 402, and the material is gathered to the constant width section 402 by the convergence section 401. The structure is simple, maintenance is convenient, and the constant width effect is good.

[0042] Furthermore, it also includes a hopper 6, which is arranged on the frame 1 and located above the crushing roller 2. The hopper 6 has a feed port and a discharge port, and the discharge port faces the meshing position of the two crushing rollers 2. A mud pressing roller 7 is arranged on the frame 1 and located in the fixed width section 402. A mud pressing space 701 is formed between the mud pressing roller 7 and the material guide trough 4.

[0043] In this embodiment, a hopper 6 is designed for materials to enter between the two crushing rollers 2. The design of the hopper 6 ensures the safety of operators when loading materials and meets the needs of continuous loading. A mud pressing roller 7 is designed to achieve height and shaping of materials passing through the uniform distribution plate 5. The structure is simple and easy to maintain.

[0044] Furthermore, it also includes a first rotating drive member 8, which is arranged on the frame 1 and drives the crushing roller 2 to rotate, and a second rotating drive member 9, which is arranged on the frame 1 and is used to drive the mud pressing roller 7 to rotate, and the second rotating drive member 9 is located above the uniform distribution plate 5.

[0045] In this embodiment, a first rotating drive member 8 is designed to drive the crushing roller 2 to rotate, and a second rotating drive member 9 is designed to drive the mud pressing roller 7 to rotate. Both the first rotating drive member 8 and the second rotating drive member 9 are universal motors, which are easy to maintain and have higher versatility.

[0046] Further, the uniform distribution plate 5 includes a support portion 502 slidably disposed on the frame 1 , and a V-shaped portion 503 disposed on the support portion 502 , with the small end of the V-shaped portion 503 facing the crushing roller 2 .

[0047] In this embodiment, the uniform distribution plate 5 is designed to be composed of two parts, a support portion 502 and a V-shaped portion 503. The support portion 502 is used to support the V-shaped portion 503, wherein the support portion 502 is slidably set on the frame 1, and the height of the uniform distribution space 501 is adjusted by adjusting the position of the support portion 502, wherein the small end of the V-shaped portion 503 faces the crushing roller 2. When the material moves with the movement of the filter cloth 3, the material with high middle and low sides will divert the high sludge in the middle to both sides under the action of the V-shaped portion 503, thereby completing the preliminary height setting of the material.

[0048] Further, the frame 1 has a guide groove 101, and the support portion 502 has a guide portion, and the guide portion is slidably arranged in the guide groove 101. In this embodiment, the frame 1 is designed with a guide groove 101, and the support portion 502 is designed with a guide portion, and the height of the uniformly distributed space 501 is adjusted by sliding the guide portion in the guide groove 101, and the structure is simple and easy to maintain.

[0049] Furthermore, the V-shaped portion 503 is tilted toward the filter cloth 3. In this embodiment, if the material is large after passing through the V-shaped portion 503, it will accumulate at the large end of the V-shaped portion 503. If the material accumulates too much, it will cause the material to be squeezed out of the material guide trough 4 from the large end of the V-shaped portion 503. In order to avoid this problem, the V-shaped portion 503 is tilted toward the filter cloth 3. If the material accumulates to both sides under the action of the V-shaped portion 503, the accumulated material can move backward in the higher uniform space 501, avoiding the material from being squeezed out of the material guide trough 4. The structure is simple and the labor intensity of the operator is reduced.

[0050] Further, it also includes a transfer roller body 10, which is rotatably arranged on the frame 1 and is used to drive the movement of the filter cloth 3. In this embodiment, a transfer roller body 10 for driving the movement of the filter cloth 3 is also designed, which has a simple structure, low failure rate, and is easy to maintain.

[0051] Furthermore, the mud pressing roller 7 comprises a sliding bracket 702 , which is arranged on the frame 1 , and has a guide slide groove 705 and a roller body 703 , and the roller body 703 is lifted and lowered in the guide slide groove 705 .

[0052] In this embodiment, in order to meet the larger material demand, the mud pressing roller 7 is designed to be composed of two parts: a sliding bracket 702 and a roller body 703. The height and shape of different amounts of materials are determined by lifting and lowering the roller body 703 in the guide chute 705. The structure is simple and easy to maintain.

[0053] Furthermore, the sliding bracket 702 also includes two screws 704 , which are respectively threadedly arranged at both ends of the sliding bracket 702 , and the two screws 704 are rotationally connected to both ends of the roller body 703 , and the screws 704 are used to drive the roller body 703 to move closer to or away from the filter cloth 3 .

[0054] In this embodiment, a screw 704 is designed to drive the roller 703 to move closer to or away from the filter cloth 3. The screw 704 can also be used to adjust the angle between the roller 703 and the filter cloth 3. The structure is simple and easy to maintain.
