Description

Technical Field

[0001] The utility model belongs to the technical field of filtering devices, and in particular relates to a sludge dehydration filtering device. Background Art

[0002] Dewatered sludge refers to the solid residue left after the wet sludge is dehydrated by drainage or filtration. After various dehydration treatments, the moisture content is reduced to 65% to 85% and has become wet soil-like sludge. Non-toxic dewatered sludge can be directly used as fertilizer in farmland. The precipitate in the wastewater treatment process has a moisture content of 99%. Before the sludge is treated, in order to reduce its volume for easy transportation and further treatment, part of the water must be removed.

[0003] When dewatering and filtering sludge, sedimentation is required first to separate most of the water from the sludge. Since the sludge also contains other impurities, especially some metal impurities that need to be filtered out, if metal impurities are mixed in the sludge, subsequent equipment will be damaged. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a sludge dewatering and filtering device.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A sludge dewatering and filtering device comprises carrying rods arranged on both sides of a sedimentation tank, wherein the carrying rods are slidably connected to a sliding block;

[0007] The slider is provided with a through hole matched with the carrier rod, and the slider is provided with a mounting hole vertically distributed with the through hole. The sliders on the carrier rods on both sides are plugged into the magnetic adsorption member through the mounting hole. The plug-in end of the magnetic adsorption member passes through the mounting hole, and the plug-in end of the magnetic adsorption member is plugged into the torsion rod along the radial direction.

[0008] The magnetic adsorption component is provided with an adsorption body and Z-shaped corner frames located at two ends of the adsorption body, the Z-shaped corner frames are plugged into the mounting holes, and the adsorption surface of the adsorption body is inserted into the sedimentation tank.

[0009] It is further defined that the slider is provided with a first threaded hole connected with the through hole, a bull's eye ball bearing is installed in the first threaded hole, an outer ring of the bull's eye ball bearing is provided with an external thread matched with the first threaded hole, and the ball of the bull's eye ball bearing is in contact with the carrier rod. With such a structural design, the bull's eye ball bearing is in direct contact with the carrier rod, thereby supporting the carrier rod, and reducing the difficulty of the slider moving relative to the carrier rod through the rotation of its own ball.

[0010] It is further defined that the slider is provided with a second threaded hole connected to the mounting hole, and the second threaded hole is connected to a push rod. With such a structural design, pressure is applied to the Z-shaped corner frame inserted in the mounting hole through the push rod, so as to prevent the Z-shaped corner frame from rotating when the posture needs to be maintained. The pressure applied to the Z-shaped corner frame can be canceled by loosening the push rod, so that when the magnetic adsorption component needs to be rotated out of the sedimentation tank, the corresponding degree of freedom is obtained.

[0011] It is further defined that the two ends of the torsion bar are provided with limit joints. With such a structural design, the limit joints prevent the torsion bar from being separated from the Z-shaped corner frame.

[0012] It is further defined that the adsorption body is an octahedron, the adsorption body is hollow, and the eight sides of the adsorption body are embedded with a magnetic adsorption plate. With such a structural design, the octahedron has multiple adsorption surfaces and a flat surface to install the magnetic adsorption plate, and the magnetic adsorption plate is used to provide a magnetic adsorption function.

[0013] The beneficial effects of the utility model include: being able to filter metal impurities in sludge and preventing the doping of metal impurities from causing physical damage to subsequent sludge treatment equipment. Specifically, the adsorption body of the magnetic adsorption component extends into the sedimentation tank, and while the magnetic adsorption component follows the movement of the slider, the adsorption body passes through the bottom sludge layer to adsorb the metal in the sludge layer. When the magnetic adsorption component follows the slider to pass through the entire sedimentation tank, the metal filtration of the sludge therein is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown, a sludge dewatering and filtering device of the utility model comprises a carrying rod 2 arranged on both sides of a sedimentation tank 1, and the carrying rod 2 is slidably connected to a sliding block 4;

[0030] The slider 4 is provided with a through hole 42 that matches the carrier rod 2, and the slider 4 is provided with a mounting hole 41 that is vertically distributed with the through hole 42. The sliders 4 on the carrier rods 2 on both sides are plugged with the magnetic adsorption member 8 through the mounting hole 41. The plug-in end of the magnetic adsorption member 8 passes through the mounting hole 41, and the plug-in end of the magnetic adsorption member 8 is plugged with the torsion rod 5 along the radial direction.

[0031] The magnetic adsorption member 8 includes an adsorption body 81 and Z-shaped corner frames 82 located at both ends of the adsorption body 81 . The Z-shaped corner frames 82 are plugged into the mounting holes 41 , and the adsorption surface of the adsorption body 81 extends into the sedimentation tank 1 .

[0032] In this embodiment:

[0033] The carrier rod 2 guides and carries the slider 4. The slider 4 moves along the carrier rod 2, thereby driving the magnetic adsorption member 8 to move together. The adsorption body 81 of the magnetic adsorption member 8 penetrates into the sedimentation tank 1. While the magnetic adsorption member 8 follows the slider 4, the adsorption body 81 passes through the bottom silt layer to adsorb the metal in the silt layer. When the magnetic adsorption member 8 follows the slider 4 to complete the entire sedimentation tank 1, the metal filtration of the silt therein is completed.

[0034] Subsequently, the staff twists the magnetic adsorption component 8 through the torsion bar 5 to flip the magnetic adsorption component 8 about the mounting hole 41. The magnetic adsorption component 8 detaches from the sedimentation tank 1 and flips onto the shore, exposing the adsorbed metals. The staff cleans these metals collectively. The torsion bar 5 is connected to the plug-in end of the magnetic adsorption component 8 by plugging. The torsion bar 5 can slide along the axial direction. The staff can freely adjust the length of the torsion arm to form a lever structure to save physical effort.

[0035] Preferably, the slider 4 is provided with a first threaded hole 43 connected with the through hole 42, a bull's eye ball bearing 7 is installed in the first threaded hole 43, the outer ring of the bull's eye ball bearing 7 is provided with an external thread adapted to the first threaded hole 43, and the ball of the bull's eye ball bearing 7 is in contact with the carrier rod 2. With such a structural design, the bull's eye ball bearing 7 is in direct contact with the carrier rod 2, thereby supporting the carrier rod 2, and reducing the difficulty of the slider 4 moving relative to the carrier rod 2 through the rotation of its own ball. In fact, other structural shapes can also be considered according to specific circumstances.

[0036] Preferably, the slider 4 is provided with a second threaded hole 44 connected to the mounting hole 41, and the second threaded hole 44 is connected to the push rod 6. With such a structural design, pressure is applied to the Z-shaped corner frame 82 inserted into the mounting hole 41 through the push rod 6 to prevent the Z-shaped corner frame 82 from rotating when the posture needs to be maintained. By loosening the push rod 6, the pressure applied to the Z-shaped corner frame 82 is canceled, and then when it is necessary to rotate the magnetic adsorption component 8 out of the sedimentation tank 1, the corresponding degree of freedom is obtained.

[0037] Preferably, both ends of the torsion bar 5 are provided with limit joints. With such a structural design, the limit joints prevent the torsion bar 5 from being separated from the Z-shaped corner frame 82 .

[0038] Preferably, the adsorption body 81 is an octahedron, the adsorption body 81 is hollow, and the eight sides of the adsorption body 81 are embedded with the magnetic adsorption plate 83. With such a structural design, the octahedron has multiple adsorption surfaces and a plane to install the magnetic adsorption plate 83. The magnetic adsorption plate 83 is used to provide a magnetic adsorption function.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
