[0035] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1-10As shown, the present invention is a container-type sewage treatment equipment, including a container 1 and a treatment unit 2 on the top thereof, a fence 3 is installed in the container 1, the fence 3 divides the inner cavity of the container 1 into a sedimentation chamber 101 and a filter chamber 102, and a conduit 4 connected to the treatment unit 2 is installed near the bottom of the fence 3, an overflow mechanism 5 is installed between the sedimentation chamber 101 and the filter chamber 102, a cross plate 6 is installed between the cavity walls of the filter chamber 102 near the bottom, a plurality of filter elements 7 are rotatably installed on the cross plate 6, an anti-blocking mechanism 8 for dredging the filter elements 7 is provided in the filter elements 7, a toggle mechanism 9 for driving the filter elements 7 to rotate equidistantly is installed on the top of the filter elements 7, a pull rod 10 is movably provided through the top of the filter element 7, the anti-blocking mechanism 8 and the toggle mechanism 9 are connected by the pull rod 10, and a lifting component 11 for driving the pull rod 10 is installed on the top of the container 1.

[0037] It should be noted that when in use, sewage is injected into the sedimentation chamber 101 for flocculation and sedimentation, and the overflow mechanism 5 is used to make the precipitated sewage flow into the filter chamber 102 and be filtered through multiple filter elements 7. The filtered water is finally transported by the conduit 4 to the treatment unit 2 for further purification. During the filtration process, starting the lifting component 11 can drive the pull rod 10 to slide up and down reciprocatingly. When the pull rod 10 moves upward, the anti-blocking mechanism 8 is linked to facilitate the unblocking of hard particle impurities stuck on the filter element 7. When the pull rod 10 drops and resets, it is controlled to continue sliding downward. At this time, the toggle mechanism 9 can be linked to drive the filter element 7 to rotate equidistantly, and then rise and reset to the initial state. Such a cycle can enable the anti-blocking mechanism 8 to comprehensively clean the blockages on the filter element 7.

[0038] like Figure 3 and Figure 5 As shown, the filter element 7 includes a cylinder cover 71, a filter cylinder 72, a support rod 73 and several groups of filter units 74. Multiple support rods 73 are installed on the top of the cylinder cover 71, and the cylinder cover 71 is connected to the top lower surface of the container 1 through the support rods 73. The filter cylinder 72 and the cylinder cover 71 are rotatably connected. Several groups of filter units 74 are evenly distributed along the circumference of the filter cylinder 72, and each group of filter units 74 includes a number of filter holes evenly distributed in the longitudinal direction.

[0039] It should be noted that the filter cartridge 72 is set with an opening at the bottom. The water filtered by the filter cartridge 72 can fall below the horizontal plate 6. The filter cartridge 72 is rotatably connected to the cartridge cover 71 through a bearing, and the precipitated sewage is filtered and processed using several filter holes on the filter unit 74.

[0040] like Figure 3 and Figure 6As shown, the anti-blocking mechanism 8 includes a fixed cylinder 81, a hydraulic cylinder 82, an extrusion cylinder 83, a first piston 84, a second piston 85, a sliding rod 86, a first spring 87 and a clearing piece 88. The fixed cylinder 81 is coaxially installed on the lower surface of the cylinder cover 71, the hydraulic cylinder 82 is arranged in the fixed cylinder 81, and the hydraulic cylinder 82 is connected to the fixed cylinder 81 through the extrusion cylinder 83. The first piston 84 and the second piston 85 are respectively located in the hydraulic cylinder 82 and the extrusion cylinder 83. The pull rod 10 passes through the cylinder cover 71 and extends into the hydraulic cylinder 82 to be connected with the first piston 84. The clearing piece 88 is arranged between the fixed cylinder 81 and the filter cylinder 72. The two ends of the sliding rod 86 are respectively connected to the clearing piece 88 and the second piston 85. The first spring 87 is installed in the extrusion cylinder 83.

[0041] It should be noted that hydraulic oil is provided in the hydraulic cylinder 82 located above the first piston 84. When the pull rod 10 drives the first piston 84 to slide upward, the hydraulic oil will be squeezed to enter the fixed cylinder 81, so that the hydraulic oil presses the second piston 85 to slide along the fixed cylinder 81, so that the sliding rod 86 pushes the clearing piece 88 to move away from the fixed cylinder 81. In this embodiment, in the initial state, the clearing piece 88 corresponds to one group of corresponding filter units 74. During the movement of the clearing piece 88, it is used to clear the filter holes of the filter unit 74. In order to ensure the sealing of the connection between the pull rod 10 and the top of the hydraulic cylinder 82, a sealing ring can be installed here to avoid leakage when the first piston 84 squeezes the hydraulic oil.

[0042] like Figure 3 and Figures 8-9 As shown, the toggle mechanism 9 includes a rotating ring 92 with a groove 91, an open ring 94 with a notch 93, a toggle member 95, a movable block 96 and a second spring 97. The bottom of the rotating ring 92 is connected to the top of the filter cartridge 72. Several grooves 91 are equidistantly distributed along the circumference of the inner ring of the rotating ring 92. The movable block 96 is movably plugged into the groove 91, and the movable block 96 is connected to the bottom of the groove 91 through the second spring 97. The open ring 94 is fixedly mounted on the top of the cartridge cover 71. The notch 93 is opened at one end of the open ring 94. One of the movable blocks 96 extends into the open ring 94 and contacts one end of the open ring 94 close to the notch 93.

[0043] It should be noted that the number of circumferentially distributed grooves 91 is equal to the number of circumferentially distributed filter units 74, and the angle between two adjacent grooves 91 is equal to the angle between two adjacent groups of filter units 74. Here, the angle is set as a. The toggle 95 can rotate reciprocally, and the angle of each rotation is also a. In this embodiment, the end of the movable block 96 located outside the groove 91 is arranged in an arc structure. When the toggle 95 rotates counterclockwise, it is blocked by the movable block 96, so that the toggle 95 can drive the rotary ring 92 to drive the filter cartridge 72 to rotate by an angle a. Then, the toggle 95 rotates clockwise by an angle a to reset. During the reset process, the arc surface structure at the end of the movable block 96 can contract adaptively under the extrusion of the toggle 95. At the same time, the opening ring 94 can be used to limit the clockwise rotation of the rotary ring 92. After the toggle 95 is completely reset, the second spring 97 can pop out the movable block 96 again. Repeating this way can make the filter cartridge 72 rotate counterclockwise by an angle a each time, so that several groups of filter units 74 can be dredged in sequence.

[0044] As Figure 5 and Figure 10 shown, the toggle 95 includes a sleeve 951, a lever 952, a spiral groove 953 and a longitudinal movable groove 954. The sleeve 951 is sleeved on the pull rod 10, and the sleeve 951 is rotatably connected to the cylinder cover 71. One end of the lever 952 is connected to the outer pipe wall of the sleeve 951 near the top, and the other end of the lever 952 extends into the notch 93. The spiral groove 953 and the longitudinal movable groove 954 are both arranged on the inner pipe wall of the sleeve 951. The bottom end of the longitudinal movable groove 954 communicates with the top end of the spiral groove 953. A spiral block 15 adapted to the spiral groove 953 is installed on the pull rod 10. When the spiral block 15 slides down along the spiral groove 953, the sleeve 951 rotates. When the spiral block 15 rises along the longitudinal movable groove 954, the sleeve 951 does not rotate.

[0045] It should be noted that the spiral block 15 is in a critical state in the initial state. That is to say, the spiral block 15 is located in the longitudinal movable groove 954 at this time, but its bottom end just corresponds to the top end of the spiral groove 953. In this state, when the pull rod 10 rises, it drives the spiral block 15 to rise along the longitudinal movable groove 954. During this process, the sleeve 951 will not rotate. When the spiral block 15 descends and resets to the initial state, if the pull rod 10 continues to drive the spiral block 15 to descend, at this time, the spiral block 15 will move downward as a whole along the track of the spiral groove 953 and drive the sleeve 951 to rotate counterclockwise during the downward movement.

[0046] As Figures 6-7 shown, the dredging member 88 includes an arc plate 881 and a convex pin 882. One side of the arc plate 881 is attached to the outer cylinder wall of the fixed cylinder 81 and is connected to the end of the slide rod 86. A plurality of convex pins 882 are evenly distributed longitudinally along the arc plate 881, and the plurality of convex pins 882 correspond to a plurality of filter holes of one group of filter units 74.

[0047] It should be noted that the cross-section of the convex pin 882 is slightly smaller than that of the filter hole, which facilitates the smooth insertion of the convex pin 882 into the corresponding filter hole for dredging. The number of convex pins 882 is equal to the number of filter holes on each group of filter units 74 and the positions correspond to each other. That is to say, when the arc-shaped plate 881 moves away from the fixed cylinder 81, it can drive the convex pin 882 to insert into the filter hole on the corresponding filter unit 74.

[0048] As Figures 1-3 shown, the lifting assembly 11 includes an inverted U-shaped plate 111, a motor 112, a reciprocating lead screw 113 and a cross beam 114. The top end of the pull rod 10 penetrates through the top of the container 1 and is connected to the cross beam 114. The reciprocating lead screw 113 is rotatably installed on the top of the container 1. The cross beam 114 is threadedly sleeved on the reciprocating lead screw 113. The top end of the reciprocating lead screw 113 is connected to the output end of the motor 112. The inverted U-shaped plate 111 is installed on the top of the container 1 and is used to support the motor 112.

[0049] It should be noted that starting the motor 112 facilitates driving the reciprocating lead screw 113 to rotate, thereby driving the cross beam 114 sleeved with the thread to move up and down reciprocally, and then driving the pull rod 10 to slide up and down reciprocally by means of the cross beam 114.

[0050] As Figure 3 and Figure 5 shown, a longitudinally arranged cleaning brush 12 is installed on the inner side wall of the enclosure 3. The bristles on the cleaning brush 12 are in contact with the outer cylindrical wall of the corresponding filter cylinder 72. A water inlet 13 is provided at the side wall of the container 1 near the top, and a sewage outlet 14 with a sewage valve is provided at the side wall of the container 1 near the bottom.

[0051] It should be noted that since the filter cylinder 72 can rotate counterclockwise at equal angles each time, it is convenient to clean the outer surface of the filter cylinder 72 by using the cleaning brush 12, thereby further improving the cleaning effect. It is convenient to introduce the sewage to be treated into the sedimentation chamber 101 by using the water inlet 13, and it is convenient to discharge the sediment in the sedimentation chamber 101 by opening the sewage valve on the sewage outlet 14.

[0052] As Figure 2 and Figure 4 shown, the overflow mechanism 5 includes a movable frame 51, a movable column 52, a cylinder 53, an inclined through groove 54 and a transverse through groove 55. The inclined through groove 54 is opened on the side wall of the enclosure 3. The movable frame 51 is slidably installed between the outer side wall of the enclosure 3 and the inner side wall of the container 1, and the movable frame 51 covers the inclined through groove 54. The transverse through groove 55 is opened on the top of the container 1. The movable column 52 is installed on the top of the movable frame 51, and the movable column 52 passes through the transverse through groove 55. The cylinder 53 is installed on the top of the container 1, and its piston rod is connected to the movable column 52.

[0053] It should be noted that when the movable frame 51 covers the oblique through groove 54, it can prevent sewage from entering the oblique through groove 54, thereby facilitating sufficient time for sewage to settle and flocculate. When the cylinder 53 is started to push the movable column 52 to gradually move along the transverse through groove 55, the movable column 52 will drive the movable frame 51 to move synchronously, thereby making the top position of the oblique through groove 54 connect with the sedimentation chamber 101, facilitating the sewage to enter the filter chamber 102 from the top position of the oblique through groove 54. As the water level in the sedimentation chamber 101 gradually decreases, the movable frame 51 also gradually moves horizontally, causing more and more parts of the oblique through groove 54 to connect with the sedimentation chamber 101, and the height required for the connection also gradually decreases, thereby adapting to the gradually decreasing water level, facilitating the sewage after sedimentation to fully overflow into the filter chamber 102 for filtration treatment.

[0054] An embodiment of the present invention provides a containerized sewage treatment process, comprising the following steps:

[0055] Step 1: Sewage is injected into the sedimentation chamber 101 of the container 1 for flocculation and sedimentation. After the sedimentation is completed, the overflow mechanism 5 is used to allow the precipitated sewage to gradually flow into the filter chamber 102;

[0056] Step 2: Filter the overflowing sewage using the filter element 7 in the filter chamber 102, and transport the filtered water to the treatment unit 2 via the conduit 4 for further purification.

[0057] Step 3: During the filtration process, the lifting assembly 11 is started to drive the pull rod 10 to slide back and forth. During the rising process of the pull rod 10, the anti-blocking mechanism 8 can be linked to clear the blockage on the filter element 7. After the pull rod 10 is lowered and reset, it is controlled to continue to fall, which can make it linked to the toggle mechanism 9, thereby driving the filter element 7 to rotate equidistantly. This cycle can make the anti-blocking mechanism 8 clear the filter element 7 in turn.

[0058] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
