Description

Technical Field

[0001] The utility model relates to the technical field of wet garbage treatment, in particular to a separation device for wet garbage leachate. Background Art

[0002] Wet garbage leachate refers to the liquid containing water produced in domestic garbage. When wet garbage is compacted or piled, the water in it will seep out and form a liquid, which usually contains organic matter, microorganisms, nutrients and other dissolved substances. The treatment of wet garbage leachate is an important environmental management issue because untreated leachate may cause pollution to soil and water sources. In order to reduce the impact on the environment, wet garbage leachate is usually subjected to biochemical treatment.

[0003] During the transfer of wet garbage, wet garbage leachate will be produced. When the leachate is in the front-end collection section, a water pump is generally used to extract the leachate. Since the leachate contains solids such as mud, short fibers, etc., these solids can easily cause water pump blockage and impeller wear. Utility Model Content

[0020] 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.

[0021] like Figure 1-Figure 2 As shown, the utility model provides a separation device for wet garbage leachate, comprising: a box body 1, a water inlet 2 is opened on one side of the box body 1, and a water outlet 9 is opened on the other side, a lower baffle 4 and an upper baffle 5 are arranged inside the box body 1, the height of the lower baffle 4 is lower than the height of the box body 1, and is used to block the settled mud and sand, and a channel for leachate to pass through is reserved between the bottom of the upper baffle 5 and the box body 1.

[0022] Among them, an oil separation area 10 is formed between the lower baffle 4 and the upper baffle 5, one side of the oil separation area 10 is a sedimentation area, and the other side is a slag separation area, the water inlet 2 is connected to the sedimentation area, and a coarse slag discharge port 3 is opened at the bottom of the sedimentation area, and a fine slag discharge port 7 is opened at the bottom of the slag separation area.

[0023] Specifically, a slag separation barrel 6 is set in the slag separation area. The slag separation barrel 6 is made of a filter screen with an aperture of 2mm to 4mm. The slag separation barrel 6 is used to filter short fibers larger than 4mm in the leachate so that the short fibers are isolated outside the slag separation barrel 6. A rubber pad 8 is set on one side of the slag separation barrel 6. The rubber pad 8 can be removed from the slag separation barrel 6 to facilitate regular replacement of the rubber pad 8. The water outlet 9 passes through the rubber pad 8 and extends into the slag separation barrel 6. The rubber pad 8 plays a sealing role to isolate the leachate before filtration from the leachate after filtration to prevent short-circuiting.

[0024] Furthermore, the box body 1 is fixedly installed with a motor 13, and a transmission sprocket 11 is fixedly installed on the output end of the motor 13 and the slag separator 6. A chain 12 is arranged between the two transmission sprockets 11, and the two transmission sprockets 11 are connected through the chain 12. The motor 13 drives the transmission sprocket 11 fixed at the output end to rotate, and drives the transmission sprocket 11 fixed on the slag separator 6 to rotate through the chain 12, thereby driving the slag separator 6 to rotate.

[0025] In this embodiment, wet garbage leachate is introduced into the sedimentation area through the water inlet 2 and gathered in the sedimentation area. The silt with a density greater than that of the liquid naturally settles in front of the lower baffle 4. The coarse slag discharge port 3 is opened for regular slag discharge. After the liquid and silt in the leachate are separated in the sedimentation area, the leachate passes over the lower baffle 4 from above and enters the oil separation area 10. The operator regularly removes the floating oil in the oil separation area 10 to separate the grease in the leachate. The leachate below the floating oil passes over the upper baffle 5 from below and enters the slag separation area. The motor 13 is turned on and the slag separation barrel 6 rotates. During the rotation, the slag separation barrel 6 isolates the short fibers on the outside, and the leachate after filtering the short fibers enters the inside of the slag separation barrel 6 and is discharged outwardly from the water outlet 9. The fine slag discharge port 7 is opened to regularly discharge the short fibers gathered in the slag separation area.

[0026] It can be understood that the solid content in the leachate is greatly reduced by filtering the silt and short fibers in the leachate through the separation device of the wet garbage leachate, making the subsequent treatment of the leachate easier, reducing the equipment failure rate, making the water pump less likely to be blocked by dirt, and reducing the wear of the impeller.

[0027] In the present application, the box body 1 is also provided with a high-pressure nozzle 14, which is located obliquely above the slag separator 6. The high-pressure nozzle 14 is connected to an external water supply system to regularly spray 60°C hot alkaline water onto the rotating slag separator 6, thereby cleaning the slag separator 6 and keeping the entire device in good operating condition.

[0028] Working principle: wet garbage leachate is passed into the sedimentation area through the water inlet 2 and gathered in the sedimentation area. The silt with a density greater than that of the liquid naturally settles in front of the lower baffle 4. The coarse slag discharge port 3 is opened for regular slag discharge. After the liquid and silt in the leachate are separated in the sedimentation area, the leachate passes over the lower baffle 4 from above and enters the oil separation area 10. The operator regularly removes the floating oil in the oil separation area 10 to separate the grease in the leachate. The leachate below the floating oil passes over the upper baffle 5 from below and enters the slag separation area. The motor 13 is turned on and the slag separation barrel 6 rotates. During the rotation, the slag separation barrel 6 isolates the short fibers on the outside. The leachate after filtering the short fibers enters the inside of the slag separation barrel 6 and is discharged outward from the water outlet 9. The fine slag discharge port 7 is opened to regularly discharge the short fibers gathered in the slag separation area.

[0029] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
