[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0025] See also Figures 1 to 4In the utility model, a sediment discharge device for a sewage treatment tank comprises a sewage tank 1, parallel linear guide rails 2 are installed on both sides of the sewage tank 1, a moving frame 3 is installed on the top between the two linear guide rails 2, two vertical rods 4 are fixedly connected to the moving frame 3, a sewage collecting device 5 is installed at the bottom between the two vertical rods 4, a driving member 6 is installed on the left side of the top of the moving frame 3, the driving member 6 passes downward through the left vertical rod 4 and is connected and matched with the sewage collecting device 5 at the bottom, a sewage suction mechanism 7 is installed on the left side of the top of the moving frame 3, the sewage suction mechanism 7 is connected and matched with the sewage collecting device 5, a water collecting box 8 is installed on the right side of the sewage tank 1, and a filtering sewage discharge mechanism 9 matched with the sewage suction mechanism 7 is installed between the top of the water collecting box 8 and the sewage tank 1;

[0026] The sewage collecting device 5 includes an arc-shaped cover 51 and a first hinge 52. A rectangular collecting slot 53 is provided on the front of the arc-shaped cover 51. The first hinge 52 is rotatably installed inside the arc-shaped cover 51. The bottom side of the arc-shaped cover 51 is slidably connected to the bottom of the sewage pool 1. Both ends of the arc-shaped cover 51 are in sliding contact with the side wall of the sewage pool 1.

[0027] In the utility model, the sewage pool 1 is used as the main body of the device. First, sewage is injected into the sewage pool 1 and allowed to settle. At the same time, two linear guide rails 2 are started to drive the moving frame 3 to move to the back end of the sewage pool 1. After the sediment is settled to the bottom of the pool, the linear guide rails 2 are started synchronously to drive the moving frame 3 to move slowly, so as to drive the sewage collecting device 5 to run synchronously along the bottom of the pool, and at the same time, the sewage collecting device 5 is started to collect and turn over the sludge at the bottom, and at the same time, the sewage suction mechanism 7 is started to suck the collected sludge from the sewage collecting device 5 and transport it to the filtering and draining mechanism 9 as the sewage collecting device 5 moves. After the water-containing sludge is discharged into the filtering and draining mechanism 9, the filtering and draining mechanism 9 is started to transport the sludge backward in a straight line and discharge it, and the sucked water directly falls into the inside of the water collecting box 8 to achieve separation, and the shell achieves synchronous drainage while adsorbing the sediment, saving cleaning time and improving efficiency.

[0028] By starting the driving member 6 to drive the first hinge dragon 52 to rotate, as the arc cover 51 moves forward, the sludge is squeezed into the interior through the rectangular collecting groove 53, and the rotation of the first hinge dragon 52 realizes the turning of the sludge, which is convenient for adsorption, so that the sludge is always stirred in the arc cover 51 while the arc cover 51 moves, reducing the difficulty of adsorption, thereby realizing the device having the ability to directly discharge sediment underwater, without waiting for complete sewage discharge, reducing cleaning time, and improving sewage treatment efficiency. The semi-automatic operation saves labor costs and is more efficient. It solves the problem in the prior art that cleaning is generally performed manually, and it takes a long time to clean after the water is discharged. At the same time, the volume of the sewage sedimentation tank is large, the drainage takes a long time, and the entire operation process is very long, which reduces the sewage treatment efficiency.

[0030] In the utility model, the driving motor 62 on the positioning frame 61 is started to drive the transmission rod 63 to rotate, thereby driving the first bevel gear 64 to rotate and driving the second bevel gear 65 to rotate, thereby driving the first auger 52 to rotate, and collecting the sludge while turning it for easy adsorption.

[0031] See also Figure 1 and Figure 3 , wherein: the sewage suction mechanism 7 includes a sewage suction pump 71, an adsorption tube 72, a horizontal tube 73 and a discharge tube 74, the sewage suction pump 71 is fixedly installed on the mobile frame 3, the input end of the sewage suction pump 71 is fixedly connected to the adsorption tube 72, the output end of the sewage suction pump 71 is fixedly connected to the discharge tube 74, the bottom end of the discharge tube 74 is vertically toward the filtering and sewage discharge mechanism 9, the bottom of the horizontal tube 73 is fixedly connected to the top of the arc cover 51, and the top of the arc cover 51 is provided with through holes 511 arranged at equal distances, and the through holes 511 are upwardly connected to the inside of the horizontal tube 73.

[0032] In the utility model, by starting the sewage suction pump 71, the sludge inside the arc cover 51 is negatively adsorbed by the adsorption tube 72 and the horizontal tube 73, and the sludge is adsorbed upward through the through hole 511, and then the sludge mixed with a small amount of water is extracted and the sediment mixed with a small amount of water is discharged into the interior of the filtering and sewage discharge mechanism 9 through the discharge pipe 74. While the solid-liquid separation is being carried out, the filtering and sewage discharge mechanism 9 is started to transport and discharge the sludge, thereby realizing an automated sewage discharge effect, and the operation can be performed without waiting for the sewage to be discharged.

[0033] See also Figure 4 , wherein: the aperture of the through hole 511 at the right end is twice the apertures of the other apertures.

[0034] In the utility model, the through hole 511 with a double aperture at the right end is used to increase the amount of sludge passing through, thereby preventing the sludge pressure at the right end of the first auger 52 from being too large when the first auger 52 is running, thereby preventing the device from being damaged.

[0035] See also Figure 1 and Figure 3, wherein: the filtering and draining mechanism 9 includes a rectangular groove 91, a water filter mesh plate 92, a second hinge dragon 93 and a reduction motor 94, the bottom of the rectangular groove 91 is fixedly installed to the top of the water collecting box 8, the left side of the rectangular groove 91 is fixedly connected to the outer wall of the sewage pool 1, the water filter mesh plate 92 is fixedly installed to the bottom of the rectangular groove 91, the reduction motor 94 is fixedly installed to one end of the back side of the rectangular groove 91, the output end of the reduction motor 94 is fixedly connected to the second hinge dragon 93 through a coupling, the other end of the second hinge dragon 93 is rotatably connected to the inside of the rectangular groove 91, and a leakage port 95 is opened at the bottom of one end of the back side of the rectangular groove 91.

At the same time, while the sludge is being transported, a small amount of sewage therein directly falls into the interior of the water collecting tank 8 through the water filter mesh plate 92, thereby realizing solid-liquid separation.

[0037] See also Figure 1 , wherein: the front view cross-section of the water filter mesh plate 92 is arc-shaped, and the water filter mesh plate 92 is located directly above the water collecting tank 8.

[0038] In the present invention, the front view cross section of the water filter mesh plate 92 is arc-shaped, and the water filter mesh plate 92 is located directly above the water collecting box 8. The arc-shaped water filter mesh plate 92 makes the sludge more concentrated, convenient for transportation, and at the same time makes the solid-liquid separation effect better.

[0039] See also Figure 3 , wherein: the water collecting box 8, the sewage pool 1 and the water filter screen 92 are of equal length, the rectangular groove 91 is longer than the sewage pool 1, and the leakage port 95 is not connected to the water collecting box 8 downward.

[0040] In the utility model, by coordinating the lengths of the water collecting tank 8, the sewage pool 1 and the water filter screen 92, the device can simultaneously discharge sewage and perform solid-liquid separation operations while sucking out the sediment, and the integrated continuous operation is more efficient. The leakage port 95 is staggered with the water collecting tank 8 to prevent sludge from falling into the interior of the water collecting tank 8, and the structure is more reasonable.
