[0024] The effect achieved by the entire Example 1 is that when the sludge dewatering device for industrial wastewater treatment is in use, the top cover 201 is opened, and the inner barrel body 601 is placed on the top of the bearing plate 603, so that the center of the bottom of the inner barrel body 601 movably penetrates through the outer surface of the second threaded rod 605. A plurality of rectangular blocks 608 fixedly arranged at equal intervals at the bottom thereof are correspondingly inserted into a plurality of rectangular grooves 607, playing a limiting role. The wing nut 606 is placed on the top of the second threaded rod 605, and the wing nut 606 is screwed, so that it threadedly moves on the outer surface of the second threaded rod 605 until it tightly abuts against the inner bottom of the inner barrel body 601, playing a fixing role. The sludge containing industrial wastewater is poured into the inner barrel body 601, or the sludge is loaded into a woven bag, and the woven bag containing the sludge is placed in the inner barrel body 601 for use. When the top cover 201 is closed, the first threaded rod 204 of the supporting setting is inserted into the first connecting block 202 and the second connecting block 5 at its position, and the hand wheel 203 is rotated, so that the first threaded rod 204 threadedly moves in the first connecting block 202 and the second connecting block 5 in sequence, and the top cover 201 will tightly cover the top of the outer barrel body 1.

During cleaning, after the dehydrated dry sludge is taken out, the wing nut 606 is screwed, so that it is screwed out from the outer surface of the second threaded rod 605 under the action of rotation. The two convex blocks 602 are respectively pulled upward by pressing, so that the inner barrel body 601 is taken out from the outer barrel body 1, and the inner wall of the outer barrel body 1 and the inner barrel body 601 are respectively cleaned, avoiding the need for personnel to clean inside the narrow equipment and improving the cleaning effect of the sludge dewatering device for industrial wastewater treatment.

[0025] Example 2, as Figures 1 - 5 shown, an outer ring block 205 is fixedly connected to the bottom of the top cover 201 near the edge. The outer ring block 205 and the inner barrel body 601 are in a supporting setting. An inner ring block 206 is fixedly connected to the bottom of the top cover 201 near the center. The inner ring block 206 and the inner barrel body 601 are in a supporting setting.

[0026] The effect achieved by the entire Embodiment 2 is that when in use, when the top cover 201 is tightly fixed to the top of the outer barrel body 1, the top of the inner barrel body 601 is located between the outer ring block 205 and the inner ring block 206 respectively provided at its bottom, playing a limiting role. When the inner barrel body 601 rotates at a high speed, the outer surface on one side of its top will rotate in a limited manner between the outer ring block 205 and the inner ring block 206, avoiding the uneven placement of sludge in the inner barrel body 601 during high-speed rotation, resulting in the center of gravity of the inner barrel body 601 shifting and being prone to severe jitter in the initial stage, thus improving the stability of the sludge dewatering device for industrial wastewater treatment.

[0027] Working principle: When the sludge dewatering device for industrial wastewater treatment is in use, open the top cover 201, place the inner barrel body 601 on the top of the bearing plate 603, so that the center of the bottom of the inner barrel body 601 movably penetrates through the outer surface of the second threaded rod 605. A plurality of rectangular blocks 608 fixedly arranged at equal intervals at the bottom thereof are correspondingly inserted into a plurality of rectangular grooves 607, which plays a limiting role. Place the wing nut 606 on the top of the second threaded rod 605 and turn the wing nut 606 so that it moves threadedly on the outer surface of the second threaded rod 605 until it tightly abuts against the inner bottom of the inner barrel body 601, which plays a fixing role. Pour the sludge containing industrial wastewater into the inner barrel body 601, or put the sludge into a woven bag and place the woven bag containing the sludge into the inner barrel body 601 for use. When closing the top cover 201, use the first threaded rod 204 provided in a matching manner to insert the first connecting block 202 and the second connecting block 5 at its position, and turn the handwheel 203, so that the first threaded rod 204 moves threadedly in the first connecting block 202 and the second connecting block 5 in sequence, and the top cover 201 will tightly cover the top of the outer barrel body 1. Start the motor 3. When the output end of the motor 3 rotates in the inner wall of the mounting frame 4, it will drive the bearing rod 604 to rotate synchronously in the inner wall of the outer barrel body 1. The bearing plate 603 fixedly connected to the top of the bearing rod 604 and the tops of a plurality of reinforcing blocks 609 will drive the inner barrel body 601 to rotate at a high speed inside the outer barrel body 1. When the inner barrel body 601 rotates at a high speed, a centrifugal force will be generated, so that the sludge loaded inside it will, under the action of the centrifugal force, have the moisture be thrown out from the small holes evenly opened on the surface of the inner barrel body 601, which plays a role in dewatering. During cleaning, after taking out the dewatered dry sludge, turn the wing nut 606 so that it rotates out from the outer surface of the second threaded rod 605 under the action of rotation. Pull up the two convex blocks 602 respectively to take out the inner barrel body 601 from the outer barrel body 1, and clean the inner wall of the outer barrel body 1 and the inner barrel body 601 respectively, avoiding the need for personnel to clean inside the narrow equipment and improving the cleaning effect of the sludge dewatering device for industrial wastewater treatment. When the top cover 201 is tightly fixed on the top of the outer barrel body 1, the top of the inner barrel body 601 is located between the outer ring block 205 and the inner ring block 206 respectively provided at the bottom thereof, which plays a limiting role, so that when the inner barrel body 601 rotates at a high speed, the outer surface of one side of its top will rotate with limited movement between the outer ring block 205 and the inner ring block 206, avoiding the uneven placement of the sludge in the inner barrel body 601 during high-speed rotation, resulting in the center of gravity of the inner barrel body 601 shifting and being prone to severe shaking in the initial stage, and improving the stability of the sludge dewatering device for industrial wastewater treatment.

[0028] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
