Embodiment 1

[0031] A sludge treatment plant, such as Figure 1-Figure 6 As shown, a centrifugal device 1 is included, and the centrifugal device 1 includes an outer cylinder 101 and an inner cylinder 102 arranged in the outer cylinder 101, and the outer cylinder 101 is provided with a mud inlet pipe for transporting raw sludge into the inner cylinder 102 103 and a transmission mechanism 104 for rotating the inner cylinder body 102, wherein the mud inlet pipe 103 is a mud delivery hose, which extends into the inner cylinder body 102 from the side wall of the outer cylinder body 101, and the mud delivery hose needs to be inserted into the inner cylinder body 102 during use. Insert the mouth of the mud inlet pipe 103 on the outer cylinder 101, and allow the end of the mud delivery hose to penetrate into the inner cylinder 102. At this time, the upper extrusion plate 124 is at the highest point, and the upper part performs extrusion.

[0032] The inner cylinder 102 includes a cylindrical body...

Embodiment 2

[0047] Same as embodiment 1, such as Figure 11 , Figure 12 As shown, the difference is that the mud inlet pipe 103 in this embodiment includes an outer tube 131 fixed on the side wall of the outer cylinder 101 and an inner tube 132 whose end is inserted into the outer tube 131 and can slide axially along the inner wall of the outer tube 131, The inner wall of the outer tube 131 is provided with an annular spring seat 133, the annular spring seat 133 is connected with a spring 134 arranged axially along the outer tube 131, and the end of the spring 134 away from the annular spring seat 133 is connected to the inner tube 132 inserted into the outer tube 131 on the end. The end of the inner tube 132 inserted into the outer tube 131 is fixed with a pressure plate 135. The pressure plate 135 includes an annular plate 136 and a circular plate 138 connected to the middle of the annular plate 136 by two connecting rods 137. The upper surface of the annular plate 136 is provided wit...

Abstract

The invention discloses a sludge treatment device. The sludge treatment device comprises a centrifuging device, wherein the centrifuging device comprises an outer barrel and an inner barrel which is arranged in the outer barrel; the outer barrel is provided with a sludge inlet pipe for conveying raw sludge into the inner barrel and a transmission mechanism for driving the inner barrel to rotate; the inner barrel comprises a barrel-shaped body; a plurality of water holes are uniformly distributed in the side wall of the barrel-shaped body; a barrel-shaped framework is arranged inside the barrel-shaped body; the barrel-shaped framework comprises an upper round ring, a lower round ring and four connecting rods for connecting the upper round ring and the lower round ring; a piece of barrel-shaped gauze is arranged outside the barrel-shaped framework in a sleeving manner; the barrel-shaped gauze is compressed on the inner wall of the barrel-shaped body through the barrel-shaped framework. According to the sludge treatment device, the gauze is arranged in the barrel. Compared with a filter screen, the gauze has the advantage that mud containing more moisture can be blocked on the inner side of the gauze instead of being thrown away, so that the sludge-water separation can be realized to the maximum extent.

Description

technical field [0001] The invention relates to a sludge treatment device. Background technique [0002] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complex and expensive part of the operation of the sewage treatment system. [0003] In the prior art, mud-water separation is generally performed first when sludge is treated, that is, the raw sludge is pumped from the secondary sedimentation tank to another tank through a sludge pump to separate from the supernatant. Before the separation process, the raw sludge is generally concentrated. In the existing technology, mechanical treatment methods such as vacuum filtration and centrifugation are used to treat the sludge into a semi-solid form, and then the treated sludge is tre...
