Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a screw extrusion type water treatment integrated machine. Background Art

[0002] Sludge concentration is often involved in the sewage treatment process. Sludge concentration is an effective method to reduce the moisture content and volume of sludge. Sludge concentration mainly reduces the interstitial water of sludge. The concentrated sludge is similar to a paste and still maintains fluidity. Flocculation sewage treatment is a common water treatment technology. By adding flocculants, suspended matter and colloidal substances in sewage are condensed into larger flocs, and then separated from the water by sedimentation or filtration.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example, see Figures 1 to 8 , a screw extrusion type water treatment integrated machine, comprising a sewage flocculation treatment tank body 1, the top of the sewage flocculation treatment tank body 1 is connected to a sludge recovery tank 2 through a mounting bracket (not shown in the figure), a sludge squeezing tray 3 is arranged above the sludge recovery tank 2, and a covering cover is arranged on the top of the sludge squeezing tray 3;

[0036] Among them, the mounting bracket is a bracket for supporting the structural member, which is an existing supporting technology, and the mounting bracket is not shown in the figure.

[0037] Further, the covering cover includes an inner support plate 17 connected to the mounting bracket, an inclined guide plate 18 arranged corresponding to the inner connection ring 16, and a pressure plate 19 corresponding to the rotating filter plate 10;

[0038] The inclined guide plate 18 gradually tilts downward from the inside to the outside, which ensures that when the sludge is transported from the extrusion cone ring 11 to the inclined guide plate 18 under the action of the conveying extrusion screw 14, it can be gradually squeezed and filtered in the process of moving outward, and finally transported to the position of the pressure plate 19. The rotating filter plate 10 arranged below the pressure plate 19 will rotate at a high speed, and the sludge will be thrown out into the extrusion drying tank 5 under the action of centrifugal force.

[0039] A conveying motor 20 is disposed on the inner support plate 17 . The conveying motor 20 is a prior art and will not be described in detail herein. The output end of the conveying motor 20 is fixedly connected to the conveying extrusion screw member 14 .

[0040] A mounting groove 4 is provided in the sludge squeezing tray 3, and an extrusion drying groove 5 is provided around the mounting groove 4, and an eccentric extrusion component is provided in the extrusion drying groove 5;

[0041] Among them, the extrusion drying groove 5 is set in a "V" shape in cross section and has a fan-shaped opening. The extrusion drying groove 5 can concentrate the sludge after being thrown out on the bottom, so that it enters the eccentric extrusion component from the arc-shaped extrusion opening 27 set at the bottom, realizing eccentric extrusion filtration of the sludge.

[0042] The eccentric extrusion assembly includes an eccentric inner toothed disc 6 and an extrusion tooth set 7 meshingly connected to the eccentric inner toothed disc 6. The extrusion tooth set 7 is composed of a plurality of teeth distributed in an annular shape, and a connecting end ring 8 is fixedly provided at both ends thereof. The gap between the extrusion tooth set 7 is used for sludge feeding.

[0043] Furthermore, an arc-shaped extrusion port 27 is opened in the extrusion drying tank 5, and the connecting end ring 8 is rotatably connected to the inner wall of the arc-shaped extrusion port 27. A sludge extrusion port 29 is opened at the bottom of the arc-shaped extrusion port 27, and a sewage extrusion filter port 28 is opened on the side wall, wherein a filter net is arranged in the sewage extrusion filter port 28 to ensure the filtering effect.

[0044] A further advantage of adopting the above is that when the eccentric inner toothed disc 6 rotates, it will drive the extrusion tooth group 7 meshing with it to rotate. During this process, the sludge entering from the upper arc-shaped extrusion port 27 will be driven and transported during the rotation, and due to the eccentric setting, the sludge will experience a process of first meshing and then falling off, and will be gradually squeezed between the eccentric inner toothed disc 6 and the extrusion tooth group 7 (from a position with a large space to a position with a small space, for details, please refer to the principle of the internal gear pump), so that the water squeezed out during the extrusion process is discharged from the sewage extrusion port 28, and in the process of the eccentric inner toothed disc 6 and the extrusion tooth group 7 falling off, the sludge will fall from between the teeth (the effect of the high-frequency vibration device 32) into the sludge recovery tank 2, thereby ensuring that the sludge can be fully dehydrated and achieving the effect of integrated dehydration.

[0045] A driving motor 9 is arranged on the sludge squeezing plate 3, and an output end of the driving motor 9 is connected to a rotating filter plate 10 through a transmission assembly. The rotating filter plate 10 is rotatably arranged in the mounting groove 4, and a water filter port 21 is arranged at the bottom of the mounting groove 4. The water filter port 21 is used to discharge the filtered water and is used to allow the sewage to flow into the sewage flocculation treatment tank 1.

[0046] Furthermore, the transmission assembly includes a transmission cavity provided in the sludge squeezing plate 3, a transmission sleeve shaft 22 is provided in the transmission cavity, the top of the transmission sleeve shaft 22 penetrates into the mounting groove 4, and is fixedly connected to the rotating filter plate 10;

[0047] The transmission cavity is an annular cavity, which is arranged outside the vertical extrusion conveying pipe 12. The vertical extrusion conveying pipe 12 passes through the cavity without affecting the effect of conveying sludge.

[0048] The outer wall of the transmission sleeve shaft 22 is fixedly connected with a driving gear ring 23, and the output end of the driving motor 9 passes through the transmission cavity and is fixedly connected with a driving gear 24 meshing with the driving gear ring 23;

[0049] A transmission helical gear plate 25 is fixedly connected to the outer wall of the transmission sleeve shaft 22 , and an eccentric shaft 26 is fixedly connected to the eccentric inner gear plate 6 . The eccentric shaft 26 penetrates into the transmission cavity and is fixedly connected to a helical gear meshing with the transmission helical gear plate 25 .

[0050] The inner wall of the rotating filter disc 10 is connected to a vertical extrusion conveying pipe 12 through an extrusion conical ring 11. The vertical extrusion conveying pipe 12 extends downward to the interior of the sewage flocculation treatment tank 1 and is fixedly connected to a gathering collection cylinder 13. A conveying extrusion screw member 14 for conveying sludge is arranged in the vertical extrusion conveying pipe 12. The conveying extrusion screw member 14 is a Jiaolong conveying blade, which is a prior art and will not be described in detail here.

[0051] The extrusion cone ring 11 is arranged above the vertical extrusion conveying pipe 12 , and an inner connecting ring 16 is arranged on the outer side wall thereof. The outer side wall of the inner connecting ring 16 is fixedly connected to the inner side wall of the rotating filter disc 10 .

[0052] The two ends of the gathering and collecting cylinder 13 are connected with arc-shaped stirring blades 15 for collecting sludge through detachable mounting parts, and the outer side wall of the arc-shaped stirring blade 15 is in sliding contact with the inner side wall of the sewage flocculation treatment tank body 1.

[0053] Furthermore, the detachable mounting parts include mounting rings 30 fixedly arranged on both sides of the gathering and collecting cylinder 13, and the two ends of the arc-shaped stirring blades 15 are detachably connected to the mounting rings 30 through plug-in connectors. A collecting opening 31 is provided on the side wall of the gathering and collecting cylinder 13 at the arc-shaped stirring blades 15, and filtering ports are densely distributed on the arc-shaped stirring blades 15, which can realize the filtering of sewage and sludge.

[0054] It should be noted that the provision of the detachable mounting part can make it more convenient when the arc-shaped stirring blade 15 needs to be replaced. The detachable mounting part is a prior art and will not be described in detail here.

[0055] The arc-shaped stirring blade 15 can be set to rotate in a clockwise direction by reversing the conveying motor 20 during the flocculation treatment of sewage (refer to Figure 1 ), the rotating arc-shaped stirring blade 15 can quickly stir the sewage in the sewage flocculation treatment tank 1, so that it can quickly flocculate into agglomerates, thereby improving the flocculation efficiency. When transportation is needed, the conveying motor 20 can be rotated forward to rotate the conveying extrusion screw 14 connected thereto, so as to convey the flocculated sludge upward. The arc-shaped stirring blade 15 can be rotated counterclockwise due to its arc-shaped design. When it rotates counterclockwise, the flocculated sludge can be concentrated at the collection opening 31 and enter the gathering collection cylinder 13, so as to realize the rapid separation of sludge and sewage.

[0056] Furthermore, a high-frequency vibration device 32 is provided on the mounting bracket. The high-frequency vibration device 32 is a prior art and will not be described in detail herein. The output end of the high-frequency vibration device 32 is connected to the sludge squeezing plate 3. The bottom of the sewage flocculation treatment tank body 1 located at the bottom of the gathering and collecting cylinder 13 is provided with an aeration port for conveying high-pressure gas. The setting of the aeration port can convey the flocculated sewage upward through the gas and concentrate it above the gathering and collecting cylinder 13, so as to facilitate and quickly convey it through the conveying and extrusion screw member 14.

[0057] When the present invention treats sewage, during the sewage flocculation process, the conveying motor 20 can be reversed to make the arc-shaped stirring blade 15 rotate in a clockwise direction. The rotating arc-shaped stirring blade 15 can quickly stir the sewage in the sewage flocculation treatment tank 1, so that the sewage is quickly flocculated into agglomerates, thereby improving the flocculation efficiency.

[0058] After the flocculation treatment, the conveying motor 20 can be controlled to rotate forward so that the arc-shaped stirring blade 15 rotates counterclockwise, so that the flocculated sludge is concentratedly conveyed to the collection opening 31 and enters the gathering collection cylinder 13. Under the action of the continuously rotating conveying extrusion screw 14, the sludge is conveyed upward through the vertical extrusion conveying pipe 12. In the process of upward conveying, the effect of primary water filtration is achieved. The sludge extruded and conveyed by the conveying extrusion screw 14 enters the extrusion cone ring 11 at the installation groove 4, and is conveyed to the rotating filter disc 10 under the action of the extrusion force. In this process, the sludge is squeezed for water filtration again.

[0059] When the driving motor 9 is turned on, it drives the driving gear 24 connected thereto to rotate, thereby driving the transmission sleeve shaft 22 connected thereto through the driving gear ring 23 to rotate, so that the rotating filter disc 10 is rotated at a high speed, and the sludge transported to the rotating filter disc 10 is thrown outward into the extrusion drying tank 5 under the centrifugal force of the rotating filter disc 10, and finally enters the arc-shaped extrusion port 27 arranged at the bottom of the extrusion drying tank 5;

[0060] The transmission bevel gear plate 25 connected to the transmission sleeve shaft 22 will drive the eccentric shaft 26 connected thereto to rotate through the bevel gear. When the eccentric inner gear plate 6 rotates, it will drive the extrusion tooth group 7 meshing with it to rotate. In this process, the sludge entering from the upper arc-shaped extrusion port 27 will be driven and transported during the rotation process, and due to the eccentric setting, the sludge will experience a process of first meshing and then falling off, and will be gradually squeezed and filtered three times between the eccentric inner gear plate 6 and the extrusion tooth group 7, so that the water squeezed out during the extrusion process is discharged from the sewage extrusion port 28. In the process of the eccentric inner gear plate 6 and the extrusion tooth group 7 falling off, the sludge will fall from between the teeth (the effect of the high-frequency vibration device 32) into the sludge recovery tank 2, thereby realizing the effective dehydration of the sludge in the sewage flocculation treatment process.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
