In the utility model, when the filter screen filters and separates the sludge contained in the sewage, the driving cylinder is used to drive the pressing plate to move, so that the pressing plate can squeeze the sludge on the filter screen, so that the sewage contained in the sludge can squeeze out excess water again, so that the sludge is separated from the water body more thoroughly. At the same time, the first scraper and the second scraper on both sides of the pressing plate can clean the sludge sticking to the side wall, thereby improving the use effect of the device and making it more practical.

[0004] In the prior art, the utility model with authorization announcement number CN219792531U is named: a desludging machine for sewage treatment, which is provided with a fixed block, a slide groove, a slider, a rotating shaft, a baffle and a scraper frame, so as to facilitate filtering the sludge in the sewage by the filter plate, and scrape the sludge on the inner wall of the discharge material through the scraper frame on the baffle, so as to avoid the sludge accumulation in the discharge hole for a long time causing the discharge hole to be blocked, affecting the discharge of the sludge in the sewage.

[0005] However, both of the above two devices remove mud from sewage by squeezing, which makes the sludge discharge process complicated and inconvenient to process the removed sludge more quickly. In order to optimize the efficiency of sludge treatment, a desludging machine for sewage treatment is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with 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 of 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.

[0024] Example 1

[0025] like Figure 1 to Figure 4As shown, this embodiment proposes a desludging machine for sewage treatment, including a desludging box 1, a box cover 2 and a desludging mechanism 3. Four limit pins 8 are threadedly connected to the upper surface of the box cover 2. The box cover 2 is detachably connected to the top of the desludging box 1 through the four limit pins 8. By setting the limit pins 8, the box cover 2 can be disassembled from the top of the desludging box 1, which is convenient for regular maintenance of the components inside the desludging box 1.

[0026] The desludging mechanism 3 comprises a desludging cylinder 301 rotatably sleeved on the inner bottom wall of the desludging box 1 , a water outlet 302 opened on the outer surface of the desludging cylinder 301 , and a second sprocket 305 fixedly connected to the bottom of the desludging cylinder 301 .

[0027] When the second sprocket 305 rotates, it will drive the outer surface of the desludging cylinder 301 to rotate in the inner bottom wall of the desludging box 1. The sewage enters the rotating desludging cylinder 301 and is desludged through the water outlet 302. Clean water will be screened out into the desludging box 1 through the water outlet 302, while the sludge will remain in the desludging cylinder 301 waiting for treatment.

[0028] The bottom surface of the desludging box 1 is fixedly connected with a first servo motor 303 , the output end of the first servo motor 303 is fixedly connected with a first sprocket 304 , a chain 306 is arranged outside the first sprocket 304 , and the first sprocket 304 is transmission-connected with the second sprocket 305 via the chain 306 .

[0029] When the first servo motor 303 is started, the first sprocket 304 is rotated, and the second sprocket 305 is driven to rotate through the chain 306, so that the desludging cylinder 301 can be driven to rotate, so that the desludging cylinder 301 can desludify the sewage inside.

[0030] A second servo motor 308 is installed on the upper surface of the box cover 2, and a spiral blade 307 is fixedly connected to the output shaft end of the second servo motor 308. When the second servo motor 308 is started, the spiral blade 307 will be driven to rotate, and the spiral blade 307 will rotate in the demudification cylinder 301, and the rotation directions of the demudification cylinder 301 and the spiral blade 307 are the same, and the rotation speed of the demudification cylinder 301 is greater than the rotation speed of the spiral blade 307, so that the water in the demudification cylinder 301 can be discharged into the demudification box 1 through the water outlet 302, and at the same time, the rotation of the spiral blade 307 can transport the sludge in the demudification cylinder 301 downward, and discharge it to the outside through the bottom end of the demudification cylinder 301, so as to achieve faster demudification and mud discharge work, which is more practical.

[0031] A sealing bearing 310 is fixedly connected to the inner bottom wall of the demud box 1, and the inner wall of the sealing bearing 310 is fixedly connected to the outer surface of the demud cylinder 301. A sealing plug 311 is installed at the bottom end of the demud cylinder 301. By setting the sealing bearing 310, the rotation quality of the demud cylinder 301 can be improved, and large-area liquid leakage can be effectively prevented from occurring at the connection between the demud cylinder 301 and the demud box 1.

[0032] Example 2

[0033] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the outer surface of the desludging cylinder 301 is fixedly connected with uniformly distributed magnetic strips 309, and the magnetic strips 309 are located below the water outlet 302. By setting the magnetic strips 309, metal impurities in the sewage can be adsorbed to improve the quality of sewage treatment.

[0034] The inner wall of the desludging box 1 is fixedly connected with a filter screen 9, the outer surface of the desludging cylinder 301 is rotatably sleeved in the inner wall of the filter screen 9, and the filter screen 9 is located below the magnetic bar 309. By setting the filter screen 9, the desludged sewage can be further filtered to improve the quality of sewage treatment.

[0035] Two water inlets 4 are installed at the top of the box cover 2. The positions of the output ends of the two water inlets 4 correspond to the entrance of the top of the desludging cylinder 301. By setting the water inlets 4, it is convenient to add sewage to be treated into the desludging box 1.

[0036] Two symmetrical water outlets 5 are installed on the bottom surface of the desludging box 1 . The input ends of the two water outlets 5 are both connected to the interior of the desludging box 1 . The treated sewage can be discharged by providing the water outlets 5 .

[0037] Four brackets 6 are fixedly connected to the outer surface of the desludging box 1, and an anti-skid pad 7 is fixedly connected to the bottom surface of each bracket 6. The stability of the device can be improved by providing the brackets 6 and the anti-skid pad 7.

[0038] Working principle: When in use, the first servo motor 303 and the second servo motor 308 will be started. When the first servo motor 303 is started, the first sprocket 304 will be driven to rotate. The second sprocket 305 can be mobilized to rotate through the set chain 306. When the second sprocket 305 rotates, the desludging cylinder 301 will be rotated. At the same time, the start of the second servo motor 308 will rotate the spiral blade 307, so that the spiral blade 307 can rotate in the rotating desludging cylinder 301, and the movement states of the desludging cylinder 301 and the spiral blade 307 will not interfere with each other. Then the sewage is injected into the desludging cylinder through the two water inlets 4. In 301, the rotation of the desludging cylinder 301 will throw the water into the desludging box 1 through the water outlet 302. At the same time, the rotation of the desludging cylinder 301 will also drive the magnetic bar 309 to rotate. The magnetic bar 309 can adsorb metal impurities in the water when rotating, and then filter the water again through the filter net 9. Finally, the treated water will be discharged through the water outlet 5. At this time, sludge will remain in the desludging cylinder 301, and the rotation of the spiral blade 307 can transport the sludge in the desludging cylinder 301 downward and discharge it through the bottom end of the desludging cylinder 301, thereby optimizing the sewage treatment process, improving the desludging effect and the sludge discharge efficiency, and being more practical.
