Technical Field

[0001] This invention relates to a low-resistance, energy-saving, and environmentally friendly wastewater treatment filter press, and particularly to a low-resistance, energy-saving, and environmentally friendly wastewater treatment filter press, belonging to the field of wastewater treatment technology. Background Technology

[0002] Wastewater treatment filter press equipment is used in the wastewater treatment process. Its main purpose is to achieve solid-liquid separation through filter press. It features low resistance and energy saving, and can effectively remove solid particles from wastewater, reduce the suspended solids content, improve water quality, and provide good conditions for subsequent treatment and reuse. Low-resistance and energy-saving wastewater treatment filter press devices are widely used in municipal wastewater treatment, industrial wastewater treatment, sludge treatment and other fields. It is an important technical equipment for achieving the energy saving and emission reduction goals of the wastewater treatment industry. After the low-resistance energy-saving wastewater treatment filter press is completed, the plate frame needs to be reset by the moving control component installed on the device. The existing control component has a relatively complex structure, and during the reset process, corresponding electrical equipment is required to control the plate frame to shake off the mud cake on the plate frame. At the same time, due to the different thickness, hardness and humidity of the mud cake, the mud cake may be broken unevenly. Uneven mud cake breakage may cause equipment blockage or damage.

[0003] Therefore, there is an urgent need for a low-resistance, energy-saving, and environmentally friendly wastewater treatment filter press and its filtration method to solve the aforementioned problems. Summary of the Invention

[0007] Preferably, the limiting component includes a thrust plate disposed at one end of the support frame and a movable push plate disposed at the other end of the support frame and slidably connected to the support frame. The thrust plate is used to block a plurality of the filter press components, and the movable push plate is used to push a plurality of the filter press components to slide on the support frame.

[0008] Preferably, the extrusion assembly includes an electro-hydraulic push rod disposed on the outside of the movable push plate and connected by a connecting flange. The square frame is fixedly connected to the electro-hydraulic push rod through a limiting hole. The movable push plate and the thrust plate are parallel to each other. The thrust plate is welded and fixedly connected inside the support frame. The movable push plate is parallel to the filter press assembly. The extrusion assembly is limited to sliding by a limiting mechanism. The limiting mechanism includes a vertical plate disposed on the upper surface of the support frame and a telescopic slide rod disposed within the vertical plate. The inner end of the telescopic slide rod is fixedly connected to the outer side of the movable push plate, and the bottom end of the vertical plate is fixedly connected to the support frame by bolts.

[0009] Preferably, the filter press assembly includes a plate frame, with fixed blocks fixedly connected to both sides of the plate frame, a first semi-cylinder fixedly connected to the bottom end of the fixed blocks, and an empty chamber opened inside the plate frame, with a vibration mechanism fixedly connected inside the empty chamber. The vibration mechanism includes a central shaft, a rotating ring on the outside of the central shaft, a vibration handle fixedly connected to the outside of the rotating ring, and a protective pad fixedly connected to one end of the vibration handle.

[0010] Preferably, the travel bump assembly includes a sealing shell disposed in the mounting groove, a movable plate disposed on the inner side of the upper end of the sealing shell and slidably connected by a sealing ring, a second semi-cylinder disposed on the upper end of the movable plate, and a telescopic spring disposed on the bottom end of the movable plate, wherein an air inlet is provided on the lower side of one end of the sealing shell. The travel bump assembly also includes an air pipe that communicates with the internal sliding cavity of the telescopic slide rod, and the other end of the air pipe is connected to the air inlet.

[0011] Preferably, the plate frame is disposed inside the support frame, the fixing block is disposed on the upper side of the upper edge of the plate frame, and the arc-shaped surface of the first semi-cylinder is on the side away from the fixing block; Connectors are provided on the same side of several of the plate frames, and every two connectors are connected by a pull rope. Connectors are also provided on one side of the movable push plate and the thrust plate, wherein the outermost pull rope at one end is connected to the connector on the movable push plate, and the outermost pull rope at the other end is connected to the connector on the thrust plate.

[0012] Preferably, the sealing shell is welded and fixed to the air pipe, a plurality of second semi-cylinders are provided, the arc-shaped surface of the second semi-cylinders is provided on the side away from the moving plate, and the telescopic spring is fixedly connected to the bottom end of the inner wall of the sealing shell.

[0013] Preferably, there are several empty chambers and vibration mechanisms, which are evenly and equidistantly distributed on the inner side of the plate frame. The empty chambers and vibration mechanisms correspond one-to-one and are parallel to each other.

[0014] Preferably, a filtration method for a low-resistance, energy-saving, and environmentally friendly wastewater treatment filter press includes the following steps: S1: Sewage is injected into the filter press assembly, and then several filter press assemblies are pushed together by an electric hydraulic push rod to complete the filter press operation; S2: After the filter press is completed, the moving push plate is driven back to the initial position by the electric hydraulic push rod. When the electric hydraulic push rod is retracted, several filter press components are pulled back to the initial position by the connecting parts and the pull rope. S3: During the retraction of the moving push plate, the contraction of the telescopic slide rod compresses the internal sliding cavity, generating air pressure. The air pressure is injected into the sealed shell through the air pipe, causing the moving plate to be pushed out from the mounting slot. After the moving plate is pushed out, the first and second semi-cylinders on both sides of the plate frame come into contact during the movement of the plate frame, which causes the plate frame to bump, allowing the mud cake on the plate frame to fall off better. This bump will be transmitted to the vibration mechanism in the empty chamber inside the plate frame. The bump force acts on the rotating ring, causing the rotating ring to rotate around the central axis. The rotation of the rotating ring drives the vibration handle to shake. The protective pad at one end of the vibration handle continuously hits the inner wall of the plate frame during the shaking, generating a vibration effect. This vibration further assists in shaking off the mud cake on the plate frame. S4: Finally, several filter press components are cleaned with a high-pressure water gun to facilitate the next filter press operation.

[0015] The present invention has at least the following beneficial effects: 1. In this invention, by setting up the stroke bumping component, the squeezing component and the limiting component, after the filter press component has performed filter pressing, the plate frame can be driven to reset during the resetting process of the moving push plate using the connecting parts and the pull rope. No external control mechanism is required, the structure is simple, and the stroke bumping component controls the moving plate frame to bump, shaking off the mud cake on the plate frame and preventing equipment blockage.

[0016] 2. During the plate and frame resetting process, for mud cakes of different thicknesses, hardness and moisture, the bumps generated by the combination with the travel bumping component, plus its own vibration, can more effectively shake off the mud cakes on the plate and frame. Compared with simply relying on bumps, the addition of the vibration mechanism makes the mud cakes fall off more thoroughly and reduces the possibility of mud cake residue.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-8 As shown in the figure, this embodiment of a low-resistance, energy-saving and environmentally friendly wastewater treatment filter press includes a fixed frame 1, which is used to support the entire equipment; a support frame 2, which is supported by the fixed frame 1. The support frame 2 includes a square frame 21, with mounting grooves 22 on both sides of the square frame 21 and a limiting hole 23 in the middle of one end of the square frame 21. The support frame 2 is fixedly installed above the fixed frame 1. A travel bumping component is installed on the upper surface of one side of the support frame 2. Several filter press components 5 are slidably connected to the support frame 2. The support frame 2 is used to install the travel bump assembly and several filter press assemblies 5. The travel bump assembly is used to reset and bump the filter press assemblies 5. The filter press assemblies 5 are used to filter and shape wastewater. The filter press assemblies 5 include a plate frame 51. Fixing blocks 52 are fixedly connected to both sides of the plate frame 51. A first semi-cylinder 53 is fixedly connected to the bottom end of the fixing blocks 52. A cavity 54 is opened inside the plate frame 51. A vibration mechanism 55 is fixedly connected inside the cavity 54. The travel bump assembly includes a sealing shell 91 disposed within the mounting groove 22, a movable plate 92 slidably connected to the inner upper side of the sealing shell 91 via a sealing ring, a second semi-cylinder 93 disposed on the upper end of the movable plate 92, and a telescopic spring 94 disposed at the bottom end of the movable plate 92. An air inlet 95 is provided on the lower side of one end of the sealing shell 91. The travel bump assembly also includes an air pipe 66 communicating with the internal sliding cavity of the telescopic slide rod 62. The other end of the air pipe 66 is connected to the air inlet 95. The sealing shell 91 and the air pipe 66 are welded and fixed together. Several second semi-cylinders 93 are provided. The arc-shaped surface of the second semi-cylinder 93 is located on the side away from the moving plate 92, and the telescopic spring 94 is fixedly connected to the bottom end of the inner wall of the sealing shell 91. The contraction of the telescopic slide rod 62 compresses the internal sliding cavity, generating air pressure. The air pressure is injected into the interior of the sealing shell 91 through the air pipe 66, causing the moving plate 92 to be pushed out from the mounting groove 22. After the moving plate 92 is pushed out, the first semi-cylinder 53 and the second semi-cylinder 93 on both sides of the plate frame 51 come into contact during the movement of the plate frame 51, thereby causing the plate frame 51 to bounce, so that the mud cake on the plate frame 51 can be better removed. Furthermore, the vibration mechanism 55 includes a central shaft 551, a rotating ring 552 on the outer side of the central shaft 551, a vibration handle 553 fixedly connected to the outer side of the rotating ring 552, and a protective pad 554 fixedly connected to one end of the vibration handle 553; several empty chambers 54 and vibration mechanisms 55 are provided, and the empty chambers 54 and vibration mechanisms 55 are evenly and equidistantly distributed on the inner side of the plate frame 51. The empty chambers 54 and vibration mechanisms 55 correspond one-to-one and are parallel to each other. When bumping, the bumping force is transmitted to the vibration mechanism 55 in the empty chamber 54 on the inner side of the plate frame 51. The bumping force acts on the rotating ring 552, causing the rotating ring 552 to rotate around the central shaft 551. The rotation of the rotating ring 552 causes the vibration handle 553 to shake. During the shaking, the protective pad 554 at one end of the vibration handle 553 continuously hits the inner wall of the plate frame 51, producing a vibration effect. This vibration further assists in shaking off the mud cake on the plate frame 51.

[0021] The plate frame 51 is set inside the support frame 2, and the fixing block 52 is set on the upper edge of the plate frame 51. The arc surface of the first semi-cylinder 53 is on the side away from the fixing block 52. Connectors 10 are provided on the same side of several plate frames 51. Every two connectors 10 are connected by pull ropes 11. Connectors 10 are also provided on one side of the moving push plate 3 and the thrust plate 4. The outermost pull rope 11 at one end is connected to the connector 10 on the moving push plate 3, and the outermost pull rope 11 at the other end is connected to the connector 10 on the thrust plate 4. After the filter press is completed, the moving push plate 3 is driven back to the initial position by the electric hydraulic push rod 8. When the electric hydraulic push rod 8 is retracted, several filter press components 5 can be pulled back to the initial position for reset by using multiple connectors 10 and multiple pull ropes 11, so as not to affect the subsequent use. The extrusion assembly is used to push the limiting assembly to extrude several filter press assemblies 5; the extrusion assembly includes an electro-hydraulic push rod 8 disposed on the outside of the movable push plate 3 and connected by a connecting flange 7, a square frame 21 is fixedly connected to the electro-hydraulic push rod 8 through a limiting hole 23, the movable push plate 3 and the thrust plate 4 are parallel to each other, the thrust plate 4 is welded and fixedly connected to the inside of the support frame 2, the movable push plate 3 is parallel to the filter press assemblies 5, and the extrusion assembly is limited and slid by a limiting mechanism; The limiting component is used to limit the sliding of the pressing component; the limiting component includes a thrust plate 4 disposed at one end of the support frame 2 and a movable push plate 3 disposed at the other end of the support frame 2 and slidably connected to the support frame 2. The thrust plate 4 is used to block several filter pressing components 5, and the movable push plate 3 is used to push several filter pressing components 5 to slide on the support frame 2; when the filter pressing components 5 are pushed and pressed, the movable push plate 3 is pushed by the electro-hydraulic push rod 8, and the movable push plate 3 pushes several filter pressing components 5 together to complete the filter pressing work; Furthermore, the limiting mechanism includes a vertical plate 61 disposed on the upper surface of the support frame 2 and a telescopic slide rod 62 disposed within the vertical plate 61. The inner end of the telescopic slide rod 62 is fixedly connected to the outer side of the movable push plate 3, and the bottom end of the vertical plate 61 is fixedly connected to the support frame 2 by bolts. When the movable push plate 3 slides, the telescopic slide rod 62 also slides accordingly, thereby greatly improving the stability of the movable push plate 3 when sliding.

[0022] A filtration method for a low-resistance, energy-saving, and environmentally friendly wastewater treatment filter press includes the following steps: S1: Sewage is injected into the filter press assembly 5, and then the electric hydraulic push rod 8 pushes several filter press assemblies 5 together to complete the filter press operation; S2: After the filter press is completed, the moving push plate 3 is driven back to the initial position by the electric hydraulic push rod 8. When the electric hydraulic push rod 8 is retracted, several filter press components 5 are pulled back to the initial position by the connecting piece 10 and the pull rope 11. S3: During the recovery process of the moving push plate 3, the contraction of the telescopic slide rod 62 compresses the internal sliding cavity, generating air pressure. The air pressure is injected into the sealed shell 91 through the air pipe 66, causing the moving plate 92 to be pushed out from the mounting groove 22. After the moving plate 92 is pushed out, the first semi-cylinder 53 and the second semi-cylinder 93 on both sides of the plate frame 51 come into contact during the movement of the plate frame 51, which causes the plate frame 51 to bump, making the mud cake on the plate frame 51 fall off better. This bump will be transmitted to the vibration mechanism 55 in the empty chamber 54 inside the plate frame 51. The bump force acts on the rotating ring 552, causing the rotating ring 552 to rotate around the central axis 551. The rotation of the rotating ring 552 drives the vibration handle 553 to shake. The protective pad 554 at one end of the vibration handle 553 continuously hits the inner wall of the plate frame 51 during the shaking process, generating a vibration effect. This vibration further assists in shaking off the mud cake on the plate frame 51. S4: Finally, several filter press components 5 are cleaned with a high-pressure water gun to facilitate the next filter press operation.
