[0025] The present invention will be specifically described and illustrated below in conjunction with the embodiments.

[0026] Example 1

[0027] like Figure 1-6 As shown, the floating sealing system of the horizontal flow sedimentation tank with a traveling scraper described in the utility model comprises a sedimentation tank body 1, on which a traveling scraper is arranged, the traveling scraper comprises a scraper plate 2, the scraper plate 2 is located inside the sedimentation tank body 1, a floating sealing cover 3 is slidably arranged inside the sedimentation tank body 1, the scraper plate 2 is located below the floating sealing cover 3, a slideway 4 is penetrated through the floating sealing cover 3, a barrier layer 5 is cooperated with the slideway 4, a vertical pole 6 is arranged in the center of the scraper plate 2, the vertical pole 6 penetrates through the slideway 4 and a bearing platform 7 is arranged on the top of the vertical pole 6, an electric control box 8 is arranged on the bearing platform 7, a collar 9 is slidably arranged on the vertical pole 6, drive frames 10 are cooperated with at both ends of the collar 9, a drive wheel 11 is arranged on the drive frame 10, and the drive wheel 11 is electrically connected to the electric control box 8. The driving wheel 11, the driving frame 10, the bearing platform 7 and the electric control box 8 are isolated outside the sedimentation tank body 1 to avoid contact with the corrosive gas in the sedimentation tank body 1, prevent corrosion of metal parts, reduce the risk of leakage and short circuit of electrical components, and extend the service life of the equipment; the driving wheel 11 is controlled by the electric control box 8, and the driving wheel 11 drives the driving frame 10, and then drives the scraper 2 to move, thereby realizing the scraping function and improving the scraping efficiency; the slide 4 and the barrier layer 5 on the floating sealing cover 3 cooperate to enable the vertical rod 6 to move in the slide 4, and at the same time the barrier layer 5 blocks the leakage of corrosive gases to ensure safe and reliable operation of the equipment.

[0028] The sedimentation tank body 1 includes a sedimentation tank 101, which is arranged in a rectangular parallelepiped shape as a whole, and track beams 102 are arranged at both ends of the sedimentation tank 101 to cooperate with the driving wheels 11. The sedimentation tank 101 is arranged in a rectangular parallelepiped shape, and has a stable structure, which is conducive to the horizontal slow flow of sewage in the sedimentation tank 101 and improves the sedimentation effect.

[0029] The floating seal cover 3 is slidably arranged in the sedimentation tank 101 in cooperation with the scraper blade 2, and a plurality of floats 13 are arranged at the bottom of the floating seal cover 3. The floats 13 enable the floating seal cover 3 to automatically rise and fall according to the liquid level fluctuation inside the sedimentation tank body 1, so as to avoid sealing failure caused by liquid level changes.

[0030] Several sliders 14 are respectively arranged on both sides of the floating seal cover 3, and several guide rails 103 are arranged on the inner wall of the sedimentation tank 101 to cooperate with the sliders 14. The sliders 14 cooperate with the guide rails 103 to make the floating seal cover 3 slide more smoothly in the sedimentation tank 101.

[0031] The height of the collar 9 is higher than the height of the floating sealing cover 3, and the height of the collar 9 is lower than the height of the bearing platform 7. The collar 9 ensures that the driving wheel 11 and the driving frame 10 can smoothly drive the upright pole 6 and the scraper blade 2 to move.

[0032] The blocking layer 5 includes a plurality of groups of blocking units 501 that are arranged opposite to each other, and the plurality of groups of blocking units 501 are evenly arranged in the slideway 4 .

[0033] The blocking unit 501 comprises a telescopic rod 5011 , one end of which passes through the side wall of the slideway 4 and is slidably disposed in the floating sealing cover 3 , and the other end of the telescopic rod 5011 is hinged with a flexible sealing ball 5012 .

[0034] A spring is arranged at one end of the telescopic rod 5011 away from the flexible sealing ball 5012, and the end of the spring away from the telescopic rod 5011 is fixedly arranged in the floating sealing cover 3. When the vertical rod 6 starts to move, the flexible sealing ball 5012 contacts the vertical rod 6, and the telescopic rod 5011 will shrink accordingly, thereby ensuring that the vertical rod 6 can move freely in the slideway 4. When the vertical rod 6 passes the position of the flexible sealing ball 5012, the telescopic rod 5011 will automatically extend, prompting the two relatively arranged flexible sealing balls 5012 to re-dock, thereby maintaining the sealing effect of the barrier layer 5.

[0035] The top of the track beam 102 is provided with a track 12 in cooperation with the driving wheel 11. The track 12 provides a running track for the driving wheel 11, ensuring that the driving wheel 11 drives the scraper blade 2 to move smoothly along a straight line, thereby improving the accuracy and efficiency of scraping mud.

[0036] A mud collecting bucket 15 is provided at the bottom of the sedimentation tank 101, and a mud discharge pipe 16 is provided on the mud collecting bucket 15. The mud collecting bucket 15 can collect the settled mud, and the mud discharge pipe 16 is convenient for discharging the mud from the mud collecting bucket 15.

[0037] Working process and principle:

[0038] 1. Initial state:

[0039] The floating seal cover 3 floats on the liquid surface in the sedimentation tank 101 through the float 13 , and the sliders 14 on both sides of the floating seal cover 3 cooperate with the guide rails 103 on the inner wall of the sedimentation tank 101 to ensure the stability of the floating seal cover 3 .

[0040] The driving wheel 11 is located on the track 12 of the track beam 102 , the collar 9 is slidably arranged on the upright 6 , and the driving frame 10 is fixed to the collar 9 .

[0041] The plurality of groups of blocking units 501 of the blocking layer 5 are arranged opposite to each other, and under the action of the spring, the surfaces of two oppositely arranged flexible sealing balls 5012 are closely fitted to form a seal.

[0042] 2. Working of scraper 2:

[0043] The electric control box 8 controls the driving wheel 11 to move along the track 12, and the driving wheel 11 drives the vertical rod 6 to move in the slideway 4 through the driving frame 10 and the collar 9. When the vertical rod 6 passes through the blocking unit 501 in the slideway 4, the flexible sealing ball 5012 is squeezed by the vertical rod 6, so that the telescopic rod 5011 contracts and allows the vertical rod 6 to pass; after the vertical rod 6 passes, the spring pushes the telescopic rod 5011 to extend, so that the flexible sealing balls 5012 on both sides are tightly fitted again to form a seal.

[0044] The evenly distributed blocking units 501 ensure that a continuous seal is formed throughout the slideway 4, effectively preventing gas leakage.

[0045] When the upright pole 6 moves, it drives the scraper blade 2 below to move synchronously. The scraper blade 2 scrapes the sludge at the bottom of the sedimentation tank 101 to the sludge collecting bucket 15 and discharges it through the sludge discharge pipe 16.

[0046] 3. Floating seal cover 3 adaptive liquid level fluctuation:

[0047] When the liquid level in the sedimentation tank 101 changes, the float 13 pushes the floating seal cover 3 to rise and fall along the guide rail 103, ensuring that the floating seal cover 3 always covers the liquid surface to prevent the corrosive gas from spreading.
