Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering treatment technology, specifically a sludge dewatering treatment device for solid waste sampling. Background Technology

[0002] Sludge is a solid waste produced during wastewater treatment. It is a flocculent material with a high water content. During the sampling process, it usually needs to be collected manually or using sampling tools. Since the collected solid waste contains water and sludge, it is usually necessary to separate the sludge and water in the collected solid waste samples.

[0003] Currently, filter bags are commonly used to separate sludge and water from collected solid waste samples. Due to the high water content of the samples, operators often need a long time to filter out some of the water, which seriously affects the efficiency of sampling and testing. Furthermore, since sludge and water are difficult to separate, it is still difficult to achieve effective separation of sludge and water in the sample by gravity or manual squeezing alone. This results in poor sampling quality, lack of uniformity and representativeness, and thus affects the accuracy of sampling and testing.

[0004] Patent document CN221397636U discloses a sludge dewatering device for solid waste sampling, comprising: an outer cylinder with drainage holes on its bottom wall; an inner cylinder rotatably disposed inside the outer cylinder, with multiple dewatering holes on its side wall; a drive motor disposed at the bottom of the outer cylinder and connected to the inner cylinder; a cover detachably disposed at the top of the outer cylinder, with an abutment portion at its center; and a scraping component comprising a disc-shaped scraper and a support rod, the scraper being adapted to the inner wall of the inner cylinder, and the end of the support rod being rotatably connected to the abutment portion. The sludge dewatering device for solid waste sampling provided by this utility model can quickly and efficiently dewater sampled sludge, thereby shortening sampling time, improving sampling efficiency, and producing uniform samples after dewatering, thus improving sampling quality. It also features a simple structure, is easy to carry and transport, and thus improves the convenience of outdoor sampling.

[0005] In the aforementioned prior art, although centrifugal dewatering can be conveniently performed, the dewatered coal water splashes between the inner and outer cylinders, causing contamination of the cylinder walls. When the equipment is reused multiple times on site, it is difficult to clean it in time, which can easily lead to cross-contamination. Therefore, a new sludge dewatering treatment device for solid waste sampling is proposed to optimize the aforementioned prior art. Utility Model Content

[0006] The purpose of this invention is to provide a sludge dewatering treatment device for solid waste sampling, so as to solve the problems mentioned in the background art.

[0027] The dewatering component 8 is confined within the outer shell 2 by the cooperation of the cap 9 and the rotating base 4. The sludge centrifugal dewatering is carried out in the upper shell 11 and the lower shell 10. The wastewater is discharged directly through the drain pipe 13, which directly avoids the outer shell 2 from being contaminated. At the same time, new samples can be dewatered by replacing the dewatering component 8, which effectively avoids the problem of cross-contamination of samples.

[0028] A plane bearing 16 is fixedly connected to the inner side of the cover 9, which makes the upper shell 11 of the dehydration component 8 fit the cover 9 more smoothly.

[0029] The filter screen cylinder 12 is equipped with a scraper 17 that is adapted to it. The scraper 17 is in contact with the inner wall of the filter screen cylinder 12 and is movable. A pull rod 18 is fixedly connected to the scraper 17.

[0036] The working principle of this utility model is as follows:

[0037] In use, unscrew the lower housing 10 and the upper housing 11. The filter screen 12 is then defined by the positioning groove 14 and positioning fins 15. Place the solid waste sample to be dehydrated into the filter screen 12. Then, assemble the lower housing 10 and the upper housing 11, and further place the dehydration component 8 into the outer housing 2. The drain pipe 13 extends through the rotating base 4. Cover the housing with the cap 9 and secure it with a buckle. Start the motor 7, which drives the rotating base 4 through the engagement of the first gear 5 and the second gear 6, thereby rotating the dehydration component 8. The centrifugal rotation dewatering effect is achieved. The water enters the lower shell 10 and the upper shell 11 through the filter screen 12 and is finally discharged through the drain pipe 13. The sludge is left in the filter screen 12, and the wastewater is finally collected and discharged by the water guide trough 19, completing the centrifugal dewatering. The cover 9 is then opened, and the dewatering component 8 is lowered and popped out from the outer shell 2 under the action of the spring 20 and the abutment ring 21. The lower shell 10 and the upper shell 11 are opened, and the filter screen 12 is then removed. The sludge sample is then hung out by the scraper 17 pulled by the pull rod 18, thus completing the dewatering treatment.
