Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a dry-wet separation and homogenization device for urban sludge. Background Art

[0002] Sludge is generated during the operation and maintenance of urban facilities related to urban life and urban life activities. According to the source, it can be divided into sewage plant sludge, water supply plant sludge, drainage pipe sludge, dredging sludge and construction mud. The properties of sludge from different sources vary greatly, and the corresponding treatment and disposal technical requirements and resource utilization methods are also different;

[0003] At present, when treating sludge, the moisture inside the sludge is often effectively treated through a dry-wet separation device.

[0004] During use, the existing rotary centrifugal separation device has a fixed total length and needs to change the rotation speed when facing sludge with different water contents. When facing sludge with high water content, the overall workload of the device is extremely high, the sludge separation effect is poor, and the service life of the device is short.

[0005] To this end, we propose a municipal sludge dry-wet separation and homogenization device to solve the existing problems. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and proposes a dry-wet separation and homogenization device for urban sludge.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a municipal sludge dry-wet separation and homogenization device, comprising a series rod, a shell, a net cylinder and a support seat, the lower surface of the shell is equipped with a support foot, the support foot is plugged with the series rod, the net cylinder is rotatably arranged inside the shell, flange heads are symmetrically installed at both ends of the net cylinder, the flange heads are located outside the shell, and a sewage outlet is opened on the lower surface of the shell.

[0008] Preferably, the flange head is rotatably connected to the housing via a bearing;

[0009] The flange head is provided with mounting holes, and the positions of the mounting holes are distributed in a ring array on the flange head.

[0010] Preferably, the upper surface of the shell is mounted with a chassis by bolts, and a gear is rotatably mounted on the chassis;

[0011] A notch matching the gear is provided at a designated position of the housing, and the gear extends into the notch;

[0012] A gear ring is installed on the outer wall of the net cylinder through bolts, and the part of the gear extending into the notch is meshed with the gear ring.

[0013] Preferably, the lower surface of the housing is symmetrically provided with supporting feet;

[0014] A series connection hole adapted to the series connection rod is symmetrically provided at the lower end of the support leg;

[0015] The series connection rod is movably inserted into the series connection hole.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] During use, the utility model of the urban sludge dry-wet separation and homogenization device can be tilted and fixed on a designated foundation surface, and the urban sludge to be treated enters from the higher end of the net cylinder. At this time, the gear is controlled to rotate through the meshing action between the gear and the gear ring, thereby driving the net cylinder to rotate. Under the centrifugal action, the sludge particles are retained in the net cylinder and finally discharged through the lower end of the net cylinder under the action of gravity, and the separated sewage falls into the shell and is finally discharged through the sewage outlet;

[0018] In this process, the sludge collides with each other and breaks up to be homogenized under the action of rotation, thus facilitating the recycling of the dehydrated sludge particles.

[0019] Furthermore, the overall length of the dry-wet separation homogenization device can be changed according to the sludge water content. When the sludge water content is low, usually less than three of the net cylinders are used for mutual serial assembly, each net cylinder is connected to each other through a flange head, and each shell is connected to each other in series through a series rod. When the sludge water content is high, usually more than three of the net cylinders are used for mutual serial assembly, and the number of the series-connected net cylinders can be changed according to actual needs;

[0020] The utility model can change the length of the dry-wet separation homogenization device according to the water content of the sludge, reduce the working load of the device, and improve the dry-wet separation effect of the sludge. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in 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 in 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.

A support leg 1 is installed on the lower surface of the shell 8, and the series rod 2 is inserted on the support leg 1. The shell 8 is rotatably provided with a net cylinder 10, and flange heads 3 are symmetrically installed at both ends of the net cylinder 10. The flange head 3 is located outside the shell 8, and a sewage outlet 14 is opened on the lower surface of the shell 8.

[0030] During use, the utility model of the urban sludge dry-wet separation and homogenization device can be tilted and fixed on a designated foundation surface, and the urban sludge to be treated enters from the higher end of the net cylinder 10. At this time, the control gear 6 rotates through the meshing action between the gear 6 and the gear ring 11, thereby driving the net cylinder 10 to rotate. Under the centrifugal action, the sludge particles are retained in the net cylinder 10 and finally discharged through the lower end of the net cylinder 10 under the action of gravity, and the separated sewage falls into the shell 8 and is finally discharged through the sewage outlet 14;

[0031] In this process, the sludge collides with each other and breaks up to be homogenized under the action of rotation, thus facilitating the recycling of the dehydrated sludge particles.

When the sludge moisture content is low, usually no more than three of the net cylinders 10 are assembled in series, and each net cylinder 10 is connected to each other through a flange head 3, and each shell 8 is connected to each other in series through a series rod 2. When the sludge moisture content is high, usually more than three of the net cylinders 10 are assembled in series, and the number of the series-connected net cylinders 10 can be changed according to actual needs.
