Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to sludge treatment equipment suitable for various water contents. Background Art

[0002] Sludge treatment is a harmless processing process of concentrating, conditioning, dehydrating, stabilizing, drying or incinerating sludge. At present, there are two forms of dehydration and drying of sludge in municipal sewage treatment plants. One is sludge with a humidity of 60% (60% humidity is in the form of mud cakes), and the other is sludge with a humidity of 80% (80% humidity is in the form of mud, not formed). The working conditions and equipment of the sewage treatment plant determine the humidity of the actual output sludge. The two sludges with different humidity have great differences in the properties of the physical state. They need to be treated separately during the sludge treatment process. Different sludge treatment equipment needs to be configured. The equipment of the treatment equipment is more troublesome, resulting in more equipment investment and poor equipment compatibility. Therefore, in view of the above situation, it is urgent to develop a sludge treatment equipment that can adapt to different humidity, save the division of labor and process, make it more compatible, and have a wider range of sludge treatment fields. It is suitable for sludge treatment equipment with a variety of moisture content to overcome the shortcomings in current practical applications and meet the current treatment and disposal needs of sludge with different moisture contents.

Rotary conveyor, the sludge block upper silo is located on the upper side of the supporting steel structure, a conveyor belt is arranged at the bottom of the outlet of the sludge block upper silo, the conveyor belt is arranged to be inclined upward, and the outlet at the other end of the conveyor belt is located above the sludge metering system, the second lifting mechanism is located on the lower side of the supporting steel structure, and a second transfer hopper is arranged on the second lifting mechanism, a dry matter conveying mechanism is arranged on the left side of the supporting steel structure, a dry matter upper silo is arranged at the lower left end of the dry matter conveying mechanism, a discharge pipe is arranged at the upper right end, a dry matter metering system is arranged below the discharge pipe, a stirring bin is arranged below the dry matter metering system and the sludge metering system, and the stirring bin is located above the second transfer hopper.

[0006] Preferably: the discharge pipe is inclined downward.

[0007] Preferably, the outlet of the screw conveyor is above the sludge metering system.

[0008] Preferably, a motor-driven agitator is provided in the stirring chamber.

[0009] The beneficial effects of the utility model are as follows: the sludge treatment equipment suitable for various moisture contents, when used, when treating sludge with a moisture content of about 60%, a forklift is used to add the sludge with a moisture content of 60% into the sludge block upper bin, the sludge falls from the bottom of the sludge block upper bin onto the conveyor belt, and the sludge with a moisture content of 60% is transported to the sludge metering system through the conveyor belt, and at the same time, the dry matter conveying mechanism sends the auxiliary materials required for production through the dry matter upper bin, the elevator discharge pipe, the dry matter metering system, and finally into the dry matter metering system, and after the dry matter and the sludge block are metered, they are sent to the mixing bin together for mixing and stirring; when using sludge with a moisture content of 80%, the sludge with a moisture content of 80% is converted from wet sludge to dry matter. The truck directly dumps the sludge into the sludge hopper, and then the first lifting mechanism lifts the first transfer hopper into the sludge storage bin, and then pours the sludge in the first transfer hopper into the sludge storage bin, and then the sludge is transported to the sludge metering system by the screw conveyor. Just like the dry matter transportation in the production of sludge blocks with a moisture content of 60%, the dry matter is also sent to the dry matter metering system at the same time. After the sludge and dry matter are proportionally measured, they are put into the mixing bin together; the mixed material falls into the second transfer hopper, and then the second lifting mechanism lifts the second transfer hopper into the sludge drying plant, and then the sludge in the second transfer hopper is spread in the sludge drying plant for drying. In summary, the utility model can adapt to sludge treatment equipment with different humidity, save division of labor and process, make it more compatible, and cover a wider range of sludge treatment fields.

A first lifting mechanism 2 is arranged on the upper side of the sludge drying plant 10 and the right side of the supporting steel structure 12, a first transfer hopper 201 is arranged on the first lifting mechanism 2, a sludge slurry feeding hopper 1 is arranged on one side of the first lifting mechanism 2, the bottom of the sludge slurry feeding hopper 1 is located above the first transfer hopper 201, two sludge slurry storage bins 3 are arranged on one side of the first lifting mechanism 2, a screw conveyor 301 is installed at the bottom of each sludge slurry storage bin 3, and the outlet of the screw conveyor 301 is above the sludge metering system 11. The silo 4 is located on the upper side of the supporting steel structure 12, and a conveyor belt 5 is arranged at the bottom of the outlet of the sludge block upper silo 4. The conveyor belt 5 is arranged to be inclined upward, and the outlet of the other end of the conveyor belt 5 is located above the sludge metering system 11. The second lifting mechanism 8 is located on the lower side of the supporting steel structure 12, and a second transfer hopper 801 is arranged on the second lifting mechanism 8. A dry matter conveying mechanism 6 is arranged on the left side of the supporting steel structure 12. The dry matter conveying mechanism 6 consists of a dry matter upper silo 601, a conveying mechanism, and a discharge pipe 602. A dry matter upper silo 601 is arranged at the lower left end of the dry matter conveying mechanism 6, and a discharge pipe 602 is arranged at the upper right.

[0022] Working principle: This sludge treatment equipment is suitable for a variety of moisture content. When used to treat sludge with a moisture content of about 60%, a forklift is used to add the sludge with a moisture content of 60% into the sludge block upper silo 4. The sludge falls from the bottom of the sludge block upper silo 4 onto the conveyor belt 5. The sludge with a moisture content of 60% is transported to the sludge metering system 11 through the conveyor belt 5. At the same time, the dry matter conveying mechanism 6 passes the auxiliary materials required for production through the dry matter upper silo 601, the elevator discharge pipe 602, and the dry matter metering system 7, and finally into the dry matter metering system 7. After the dry matter and the sludge block are metered, they are sent to the mixing bin 9 for mixing and stirring. When using sludge with a moisture content of 80%, the sludge with a moisture content of 80% is directly dumped from the wet sludge transfer vehicle into the sludge slurry inlet. The hopper 1 is then lifted by the first lifting mechanism 2 to the first transfer hopper 201 into the sludge storage bin 3, and the sludge in the first transfer hopper 201 is poured into the sludge storage bin 3, and then the sludge is transported to the sludge metering system 11 by the screw conveyor 301. Like the dry matter transportation in the production of sludge blocks with a moisture content of 60%, the dry matter is also sent to the dry matter metering system 7 at the same time. After the sludge and the dry matter are proportionally measured, they are put into the mixing bin 9 together; the mixed materials fall into the second transfer hopper 801, and then the second lifting mechanism 8 lifts the second transfer hopper 801 into the sludge drying plant 10, and then the sludge in the second transfer hopper 801 is spread in the sludge drying plant 10 for drying. In summary, the utility model can produce and process sludge with different humidity in the same set of equipment. According to the material properties of sludge with different moisture contents, different production and processing equipment can be selected to finally achieve production preparation. It not only realizes the multi-purpose use of one machine and expands the adaptability of equipment, but also reduces the investment in production equipment, and can also save land area, greatly reducing repetitive investment and construction.
