[0002] Sludge is a solid sediment produced by the water and sewage treatment process. Sludge treatment: the harmless processing process of sludge such as concentration, conditioning, dehydration, stabilization, drying or incineration.

[0003] The patent with publication number CN 214244166 U discloses a sludge squeezing device for a belt type sludge filter press, which comprises a base, supporting legs, a box body and a sludge bag. The four corners of the bottom end of the box body are fixed with supporting legs, the bottom ends of the supporting legs are fixed with a base, and the recovery box is fixed to one side of the top end of the base. The device uses a conveyor belt to drive the sludge bag to be transmitted to the bottom end of the squeezing plate, and the sludge bag can be moved on the surface of the pressing plate without manual transmission. The squeezing plate can squeeze different positions of the sludge bag, thereby improving the overall work efficiency. However, the device has the problem of loading the sludge into the belt, and then limiting it to cooperate with the squeezing plate to squeeze out the moisture in the sludge bag. However, the sludge loaded in the bag is not very fine. If there are some large sludge lumps, it is difficult to squeeze out all the moisture in the sludge bag, and it may even cause trouble for the subsequent sludge treatment. Therefore, an squeezing structure of a sludge treatment line is proposed to solve the problem that the existing sludge squeezing structure is difficult to squeeze the sludge while crushing and stirring.

The sludge is introduced to start the lifting device and the motor, which drives the lifting plate together with the crushing tool to move down into the extrusion barrel to crush the sludge agglomerates. The lifting plate continues to move downward, so that the extrusion column moves into the extrusion barrel, and cooperates with the limit plate and spring in the movable groove in the fixed frame. The crushing tool moves up to squeeze the sludge, and the sludge moisture is discharged into the bottom of the extrusion box and discharged from the drain pipe.

[0031] Example

[0032] The technical solution in the embodiment of the present application effectively solves the technical problem that the existing sludge squeezing structure is difficult to crush and stir the sludge while squeezing and draining the sludge. The overall idea is as follows:

[0033] In view of the problems existing in the prior art, the utility model provides an extrusion structure of a sludge treatment line, including a base 1, an extrusion box 2 is fixedly connected to the top of the base 1, a feed pipe 4 is provided on the right side of the extrusion box 2, a feed pipe 4 and a drain pipe 5 are provided on the front of the extrusion box 2, a notch 3 is provided on the right side of the extrusion box 2, a fixed seat 6 is fixedly connected to the inner cavity of the notch 3, an extrusion cylinder 7 is provided on the top of the fixed seat 6, a lifting device 8, a lifting plate 9, a fixed frame 10, an extrusion column 11, a motor 12 and a crushing tool 13 are provided in the inner cavity of the extrusion box 2, two sets of movable grooves 14 are provided on the inner cavity wall of the movable groove 14, a limit plate 15 and a spring 16 are provided in the inner cavity of the fixed seat 6, two sets of movable grooves 14 are provided in the inner cavity of the movable groove 14, and two sets of movable grooves 14 are provided in the inner cavity of the fixed seat 6. A second notch 17 is formed, a filter plate 18 is arranged in the second notch 17 in the fixed seat 6 in the extrusion box 2, and a collecting mechanism 19 is arranged on the side of the extrusion box 2. Sludge is introduced, and the lifting device 8 and the motor 12 are turned on to drive the lifting plate 9 together with the crushing tool 13 to move down to the extrusion cylinder 7 to crush the sludge agglomerates, and then continue to move down, so that the extrusion column 11 moves into the extrusion cylinder 7, cooperates with the limit plate 15 and the spring 16 in the movable groove 14 in the fixed frame 10, and the crushing tool 13 moves up to cooperate with the extrusion 11 to squeeze the sludge. The filter plate 18 in the second notch 17 is used to discharge the sludge moisture into the bottom of the extrusion box 1 and is discharged by the drain pipe 5, which solves the problem that the existing sludge extrusion structure is difficult to crush and stir the sludge while squeezing and draining.

[0034] Among them, the upper end of the lifting device 8 is fixedly connected to the extrusion box 2, the upper and lower ends of the lifting plate 9 are fixedly connected to the lifting device 8 and the fixed frame 10 respectively, the top of the extrusion column 11 is fixedly connected to the fixed frame 10, the crushing tool 13 is located at the outer ring of the part of the output shaft of the motor 12 that passes through the extrusion column 11, and an opening is set at the bottom of the extrusion cylinder 7.

[0035] The feed pipe 4 and the drain pipe 5 are both interconnected with the extrusion box 2. The feed pipe 4 is inclined at a certain angle and the end of the pipe mouth is flush with the extrusion cylinder 7. The outer diameter of the extrusion column 11 is slightly smaller than the inner diameter of the extrusion cylinder 7. The inclined feed pipe 4 is used to ensure that the sludge can enter the extrusion cylinder 7 accurately and quickly, and at the same time ensure that the extrusion column 11 will not interfere with the feed pipe 4 when it moves downward.

[0036] The collecting mechanism 19 is composed of a mounting frame 191, an electric telescopic rod 192, a collecting box 193, a limiting groove 194, and a roller 195; wherein the mounting frame 191 is fixedly connected to the left side of the extrusion box 2 and is used to fix the electric telescopic rod 192, and the electric telescopic rod 192 passes through the extrusion box 2 and is connected to the extrusion cylinder 7. The collection box 193 is located between the fixed seat 6 and the base 1; wherein, the second slot 17 in the fixed seat 6 outside the extrusion box 2 is located directly above the collection box 193; four groups of rollers 195 are arranged at the bottom of the collection box 193, and there are two limiting slots 194 opened at the top of the base 1; wherein, the four groups of rollers 195 are all located in the limiting slots 194 and the bottoms are in contact with the bottoms of the limiting slots 194. After the sludge is squeezed, the collection mechanism 19 is opened, and the electric telescopic rod 192 on the mounting frame 191 is cooperated to move the extrusion cylinder 7 out of the extrusion box 2 from the slot 3. During the movement, the sludge in the extrusion cylinder 7 falls from the bottom of the extrusion cylinder 7 into the collection box 193. Finally, the collection box 193 can be taken out from the base 1 in cooperation with the rollers 195 in the limiting slots 194, thereby realizing the convenience of processing and collecting the extruded sludge.

[0037] The top of the limit plate 15 is fixedly connected with a stabilizing slide rod 20, and the spring 16 is located on the outer ring of the stabilizing slide rod 20; wherein, the stabilizing slide rod 20 is located in the inner cavity of the movable groove 14, and the top passes through the fixed frame 10 and the lifting plate 9. When the extrusion column 11 continuously moves down to the extrusion cylinder 7 to extrude the sludge, under the action of the stabilizing slide rod 20, the stability of the limit plate 15 when moving upward is improved, thereby avoiding the limit plate 15 from deviating and causing damage to the shaft of the motor 12.

[0038] The inner wall of the extrusion box 2 is provided with four groups of stabilizing grooves 21, and the inner cavity of the stabilizing grooves 21 is provided with stabilizing blocks 22; wherein the stabilizing blocks 22 are fixedly connected to the lifting plate 9. The stabilizing blocks 22 in the stabilizing grooves 21 in the inner cavity wall of the extrusion box 2 are used to improve the stability of the lifting plate 9 when it moves up and down, and ensure the stability of the extrusion column 11 in the process of extruding sludge.

[0039] Working principle: When the extrusion structure of the sludge treatment line is used, the sludge is directly introduced into the extrusion barrel 7 from the feed pipe 4, the lifting device 8 and the motor 12 are turned on, and the lifting plate 9 together with the crushing tool 13 are driven to move down into the extrusion barrel 7 to crush the sludge lumps, and then continue to move down, so that the extrusion column 11 moves into the extrusion barrel 7, cooperates with the limit plate 15 and the spring 16 in the movable groove 14 in the fixed frame 10, and the crushing tool 13 moves up to cooperate with the extrusion 11 to squeeze the sludge, and uses the filter plate 18 in the second notch 17. The sludge moisture is discharged into the bottom of the extrusion box 1 and discharged from the drain pipe 5, which solves the problem that the existing sludge extrusion structure is difficult to crush and stir the sludge while squeezing and draining.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
