Description

Technical Field

[0001] This utility model relates to the field of sludge processing technology, and in particular to a sludge volume compression robot suitable for slag projects. Background Technology

[0002] Furnace slag often contains soluble salts, heavy metals, and fine particles, which can be removed by washing with water. However, after washing, the water mixes with the solid particles to form a suspension, which produces sludge after sedimentation or filtration.

[0003] In slag treatment projects, volume compression of dewatered sludge is a crucial step. Traditional sludge dewatering equipment often suffers from low compression efficiency, slow processing speed, and complex operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low compression efficiency, slow processing speed, and complex operation, and to propose a sludge volume compression robot suitable for slag projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sludge volume compression robot suitable for slag projects includes a body, the top of which is provided with multiple pressing grooves for containing sludge, and connecting plates on both sides of the body. Between two connecting plates, a pressure roller is provided for compressing the sludge in the pressing grooves. A set of reciprocating components is provided inside the body, which is used to drive the pressure rollers to compress the sludge in the pressing grooves.

[0007] In order to improve the squeezing effect on the sludge in the pressing tank, a set of bonding components is provided between the pressure roller and the two connecting plates. The bonding components are used to drive the pressure roller to actively squeeze downward.

[0008] The lifting assembly has multiple lifting plates slidably installed in the pressing tanks. The multiple lifting plates are used to send the sludge squeezed in the pressing tanks upward. The lifting assembly is located in the machine body and is used to drive the multiple lifting plates to move upward after squeezing.

[0009] In one possible design, the reciprocating assembly includes a first groove formed in the body, two limiting rods fixed in the first groove, a common sliding plate sliding on the surface of the two limiting rods, a reciprocating screw rotating in the first groove, a slider fitted on the outer wall of the reciprocating screw and used to cooperate with the helical groove of the reciprocating screw, the slider being fixed in the sliding plate, a drive motor fixed at the side end of the body, the output shaft of the drive motor being fixedly connected to the reciprocating screw through a coupling, and two connecting plates respectively fixed at both ends of the sliding plate;

[0010] The system involves starting a drive motor to rotate a reciprocating screw, which in turn drives a slider to move a sliding plate back and forth linearly within the first groove. The sliding plate, through two connecting plates, drives a pressure roller to move back and forth at the top of the machine body, thus squeezing and compressing the sludge inside the lifting plate.

[0011] In one possible design, the bonding assembly includes a rotating shaft fixed inside the pressure roller, two connecting plates each having a second groove, two arc-shaped pressure plates sliding in each of the two second grooves, two ends of the rotating shaft respectively located in the two second grooves, the arc surfaces of the two arc-shaped pressure plates being in contact with the surface of the rotating shaft, and compression springs fixed at the top ends of the two arc-shaped pressure plates respectively fixed in the two second grooves;

[0012] During the reciprocating movement of the pressure roller, the elasticity of the compression spring pushes the arc-shaped pressure plate, which can fit more tightly against the top of the machine body, ensuring the pressing effect. At the same time, the compression spring has a buffering effect, so it will not cause jamming when the sludge in the pressing groove protrudes too much.

[0013] In one possible design, the pressure roller is made of bearing steel.

[0014] In one possible design, the lifting assembly includes multiple connecting rods, each fixed to the bottom end of multiple lifting plates. A connecting groove is provided inside the machine body, and the connecting rods all extend downwards into the connecting groove. A single trapezoidal extrusion block is fixed to the bottom end of each connecting rod. A receiving groove communicating with the connecting groove is provided inside the machine body, and an extrusion plate that slides within the receiving groove and presses against the trapezoidal extrusion block is located therein. A hydraulic push rod is fixed to the side end of the machine body, and the output end of the hydraulic push rod extends movably into the receiving groove. The extrusion plate is fixed to the output end of the hydraulic push rod.

[0015] The hydraulic push rod is activated to move the extrusion plate. The extrusion plate presses the inclined surface of the trapezoidal extrusion block, causing the trapezoidal extrusion block to move upward. The trapezoidal extrusion block drives the lifting plate to move upward through multiple connecting rods, pushing out the compressed sludge.

[0016] In one possible design, the lifting assembly further includes a plurality of positioning springs fixed to the top of the trapezoidal extrusion block, the side ends of the plurality of positioning springs being fixed in the communicating groove, and the plurality of positioning springs being respectively sleeved on the surface of a plurality of connecting rods;

[0017] The trapezoidal pressing block is pushed downward by the elasticity of the positioning spring to ensure the stability of the lifting plate in the pressing groove.

[0018] In one possible design, a semi-circular head is fixed to the side end of the extrusion plate, and the semi-circular head and the inclined surface of the trapezoidal extrusion block are in extrusive contact.

[0019] In one possible design, casters are fixed at the four corners of the bottom of the body.

[0020] In this application, the reciprocating screw is driven to rotate by starting the drive motor. The rotation of the reciprocating screw drives the slide plate to move linearly back and forth in the first groove through the slider. The slide plate drives the pressure roller to move back and forth at the top of the machine body through two connecting plates, thereby squeezing and compressing the sludge in the lifting plate.

[0021] During the reciprocating movement of the pressure roller, the elasticity of the compression spring pushes the arc-shaped pressure plate, which can fit more tightly against the top of the machine body, ensuring the pressing effect. At the same time, the compression spring has a buffering effect, so it will not cause jamming when the sludge in the pressing groove protrudes too much.

[0022] By activating the hydraulic push rod, the extrusion plate is moved. The extrusion plate presses the inclined surface of the trapezoidal extrusion block, causing the trapezoidal extrusion block to move upward. The trapezoidal extrusion block drives the lifting plate to move upward through multiple connecting rods, pushing out the compressed sludge.

[0023] Beneficial effects: The sludge volume compression robot for slag projects described in this utility model achieves efficient compression of sludge through the synergistic effect of reciprocating components and bonding components, thereby increasing the sludge compression ratio, reducing sludge volume, and facilitating transportation and subsequent processing.

[0024] In this invention, a sludge volume compression robot suitable for slag projects significantly reduces the volume of the compressed sludge, thereby reducing the space and weight requirements during transportation and thus lowering transportation costs. Attached Figure Description

A reciprocating lead screw 21 rotates within the first groove 8, and a slider is fitted onto the outer wall of the reciprocating lead screw 21, which is fixed within the sliding plate 9. A drive motor 3 is fixed to the side end of the body 1, and the output shaft of the drive motor 3 is fixedly connected to the reciprocating lead screw 21 via a coupling.

[0033] Start the drive motor 3, which drives the reciprocating screw 21 to rotate. Under the action of the helical groove of the reciprocating screw 21, the slider drives the slide plate 9 to perform linear reciprocating motion in the first groove 8. The slide plate 9 drives the pressure roller 11 to move back and forth at the top of the machine body 1 through the connecting plate 10, squeezing and compressing the sludge in the pressing groove 5.

[0034] The lifting assembly includes multiple connecting rods 16, each fixed to the bottom end of the lifting plate 6.

A hydraulic push rod 4 is fixed to the side end of the machine body 1, with its output end moving outwards and penetrating into the receiving groove 18; the extrusion plate 19 is fixed to the output end of the hydraulic push rod 4.

[0035] The hydraulic push rod 4 is activated, causing the extrusion plate 19 to move outward.

The trapezoidal extrusion block 7 drives the lifting plate 6 to move upward via the connecting rod 16, pushing the compressed sludge out of the pressing trough 5.

[0036] The lifting assembly also includes a positioning spring 17 fixed to the top of the trapezoidal extrusion block 7. The side end of the positioning spring 17 is fixed in the connecting groove and sleeved on the surface of the connecting rod 16. The elasticity of the positioning spring 17 pushes the trapezoidal extrusion block 7 downward, ensuring the stability of the lifting plate 6 in the pressing groove 5. A semi-circular head 20 is fixed to the side end of the extrusion plate 19. The semi-circular head 20 makes pressing contact with the inclined surface of the trapezoidal extrusion block 7, improving the extrusion effect.

[0037] The bonding assembly includes a rotating shaft 15 fixed within a pressure roller 11, a second groove 12 formed within a connecting plate 10, and an arc-shaped pressure plate 14 sliding within the second groove 12.

A compression spring 13 is fixed to the top of the arc-shaped pressure plate 14, and the compression spring 13 is fixed within the second groove 12.

[0038] This application can be used for sludge volume compression in slag projects, and can also be used in other fields applicable to this application.

[0039] Example 2: Refer to Figures 1-4 An improvement upon Example 1: A sludge volume compression robot suitable for slag projects, applied in the field of sludge processing technology. During the reciprocating movement of the pressure roller 11, the elasticity of the compression spring 13 pushes the arc-shaped pressure plate 14, allowing the arc-shaped pressure plate 14 to tightly fit the top of the machine body 1, ensuring a pressing effect. Simultaneously, the compression spring 13 has a buffering function, preventing jamming when the sludge in the pressing groove 5 protrudes excessively.
