Description

Technical Field

[0001] This utility model belongs to the field of wastewater neutralization treatment technology, specifically relating to a filter residue device after wastewater neutralization treatment. Background Technology

[0002] In the treatment process of industrial or domestic wastewater, neutralization is a commonly used pretreatment or advanced treatment step. This involves adding acidic or alkaline agents to adjust the pH value of the wastewater, causing heavy metal ions, colloidal particles, and other substances in the wastewater to form insoluble precipitates, i.e., filter residue. To achieve solid-liquid separation, traditional treatment methods often use devices such as fixed filter plates or simple filter screens. However, these methods have the following drawbacks:

[0003] Traditional equipment has a fixed inlet position for the neutralized wastewater, which can cause residue to accumulate at the inlet, thus affecting the filtration efficiency.

[0004] Filter residue adheres to the filter screen surface for a long time, and without an effective cleaning and anti-clogging structure, it easily causes blockage of the filter screen pores, requiring frequent shutdowns for manual cleaning and increasing maintenance costs.

[0005] Therefore, we propose a filter residue device for neutralized wastewater. Utility Model Content

[0006] The purpose of this invention is to provide a filter cake device for wastewater neutralization treatment, so as to solve the problems mentioned in the background art, such as the fixed inlet position causing blockage and the easy clogging of the filter cake mesh.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter residue device for wastewater neutralization treatment, comprising a filter residue box;

[0008] The mounting frame is detachably installed on the top of the filter cake box. The mounting frame is equipped with a moving unit and a liquid conveying pipe is installed through the moving unit. Several liquid conveying nozzles are installed on the liquid conveying pipe, and the conveying direction of the liquid conveying nozzles is towards the inside of the filter cake box.

[0009] The motion unit includes a power component one fixedly installed on the side of the mounting frame, a threaded rod rotatably installed inside the mounting frame, a mounting plate threaded to the outer surface of the threaded rod, and a fixing block fixedly installed on the lower surface of the mounting plate. The output end of the power component one is fixedly connected to the threaded rod, and the liquid delivery pipe is installed through the fixing block.

[0010] Two lifting frames are provided, each of which can be detachably installed on the filter cake box. A filter cake screen is fixedly installed between the two lifting frames.

[0011] The drain pipe is installed through the lower surface of the filter cake box.

[0012] The striking unit is installed on the filter cake box and is used to strike the filter cake screen.

[0013] By adopting the above scheme, a motion unit is set up to drive the liquid delivery pipe to move horizontally, thereby switching the horizontal position of the liquid delivery nozzle. This allows for continuous adjustment of the wastewater inlet discharge position, preventing the accumulation of residue and blockage caused by a fixed discharge position, thus improving the filtration effect. By setting up a striking unit in conjunction with the filter screen, the power component drives the rotating shaft to rotate. The rotating shaft drives the mounting sleeve and elastic rod to rotate synchronously, causing the striking ball to periodically strike the lower surface of the filter screen, shaking off the filter residue attached to the filter screen pores, preventing blockage, and further improving the filtration effect.

[0014] In a preferred embodiment, several fixing plates are fixedly installed on the side of the mounting frame, and a fixing bolt is threaded onto the fixing plate. A fixing thread groove is provided on the side of the filter cake box for the fixing bolt to be screwed into.

[0015] By adopting the above solution, a fixing plate is set on the side of the mounting frame, and the fixing bolts are used to cooperate with the fixing threaded groove of the filter cake box to achieve a stable connection between the two. Compared with welding, snap-fit ​​and other connection methods, threaded connection has the advantages of convenient disassembly, high connection strength and good reusability. When it is necessary to repair the moving unit, such as the power component, or replace the liquid delivery nozzle, the mounting frame can be removed simply by unscrewing the fixing bolts, without damaging the equipment structure, thus reducing the difficulty of maintenance.

[0016] In a preferred embodiment, a plurality of guide rods are fixed on the surface of the filter cake box, and the mounting frame has guide holes for the guide rods to pass through. A support ring is fixedly installed on the outer surface of the guide rod, and the support ring is fitted and arranged on the lower surface of the mounting frame.

[0017] Using the above solution, the guide rod and the guide hole of the mounting bracket form a guiding fit, which can prevent the mounting bracket from shifting during installation and ensure the accurate relative position of the mounting bracket and the filter cake box. The support ring provides bottom support for the mounting bracket, which can distribute the weight of the mounting bracket and the moving unit, and prevent the mounting bracket from deforming or the fixing bolts from loosening due to the force exerted solely on the fixing plate. At the same time, it reduces the direct friction between the mounting bracket and the filter cake box, and extends the service life of the equipment.

[0018] In a preferred embodiment, the lifting frame is threaded with several fixing bolts, and the surface of the filter cake box is provided with a fixing thread groove for the fixing bolts to be screwed in.

[0019] Using the above solution, the lifting frame can be quickly disassembled and installed by the cooperation of fixing bolt two and fixing threaded groove two. After long-term use, the filter screen may have stubborn filter residue that is difficult to remove. At this time, fixing bolt two can be unscrewed and the filter screen can be directly taken out of the filter screen box through the lifting frame for deep cleaning such as high-pressure washing, acid washing or replacement. The operation is convenient and does not affect other parts of the filter screen box.

[0020] In a preferred embodiment, the surface of the filter screen is provided with a sealing groove, and a sealing ring is embedded in the sealing groove. The sealing ring is attached to the inner wall of the filter box.

[0021] Using the above solution, in traditional filter cake devices, gaps easily exist between the filter cake screen and the inner wall of the box, causing unfiltered wastewater and filter cake mixture to leak directly from the gaps into the drain pipe, reducing the solid-liquid separation effect. The sealing ring is preferably made of acid and alkali resistant rubber, which is suitable for the corrosive environment after the wastewater is neutralized and treated. It is embedded in the sealing groove of the filter cake screen and fits tightly with the inner wall of the filter cake box after installation, which can effectively seal the gaps and ensure that all wastewater must be filtered through the filter cake screen before being discharged, thus improving the filtration accuracy.

[0022] In a preferred embodiment, the striking unit includes a second power component fixedly installed on the side of the filter cake box, a rotating shaft rotatably installed on the filter cake box, several mounting sleeves fixedly installed on the outer surface of the rotating shaft, several elastic rods installed on the mounting sleeves, and striking balls installed at the ends of the elastic rods. The output shaft of the second power component is fixedly connected to the rotating shaft.

[0023] Using the above scheme, the second power component drives the rotating shaft to rotate, which in turn drives the mounting sleeve and the elastic rod to rotate synchronously. This causes the striking ball to periodically strike the lower surface of the filter screen, shaking off the filter residue attached to the screen pores and preventing blockage. The elastic rod has a certain degree of elasticity, which can buffer the impact force during striking and prevent rigid striking from causing deformation or damage to the filter screen.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The filter cake device after wastewater neutralization and treatment uses a motion unit to drive the liquid delivery pipe to move horizontally, thereby switching the horizontal position of the liquid delivery nozzle. This allows for continuous adjustment of the wastewater inlet discharge position, preventing the accumulation of residue and blockage caused by a fixed discharge position, and improving the filtration effect.

[0026] The wastewater neutralization and treatment filter cake device uses a striking unit in conjunction with the filter cake screen. The power component drives the rotating shaft to rotate, which in turn drives the mounting sleeve and elastic rod to rotate synchronously. This causes the striking ball to periodically strike the lower surface of the filter cake screen, shaking off the filter cake adhering to the screen pores, preventing clogging, and further improving the filter cake effect.

[0033] Please see Figure 1-5 This utility model provides a filter residue device for wastewater neutralization treatment, including a filter residue box 1. The filter residue box 1 is the main supporting structure of the device, used to hold the wastewater filter residue mixture to be filtered, and to provide a closed space for subsequent solid-liquid separation.

[0034] Mounting bracket 2 is detachably mounted on top of filter cake box 1. Its detachable design provides a mounting carrier for the motion unit and liquid delivery pipe 7, and facilitates subsequent maintenance and replacement of components.

[0035] The mounting frame 2 is equipped with a motion unit and a liquid conveying pipe 7 is installed through the motion unit. Several liquid conveying nozzles 8 are installed on the liquid conveying pipe 7, and the conveying direction of the liquid conveying nozzles 8 is towards the inside of the filter cake box 1.

[0036] The motion unit includes a power component 3 fixedly installed on the side of the mounting frame 2, a threaded rod 4 rotatably installed inside the mounting frame 2, a mounting plate 5 threadedly connected to the outer surface of the threaded rod 4, and a fixing block 6 fixedly installed on the lower surface of the mounting plate 5. The output end of the power component 3 is fixedly connected to the threaded rod 4, and the liquid delivery pipe 7 is installed through the fixing block 6. In this embodiment, the power component 3 is specifically selected as a stepper motor.

[0037] There are two lifting brackets 9, both of which can be detachably installed on the filter cake box 1. A filter cake screen 10 is fixedly installed between the two lifting brackets 9. The two lifting brackets 9 provide fixed support for the filter cake screen 10, and the detachable design makes it easy to directly remove the filter cake screen 10 for deep cleaning or replacement. The filter cake screen 10 is the core filtration component, and its pore size can be adapted according to the size of the filter cake particles to achieve filter cake interception and liquid permeation.

[0038] The drain pipe 11 is installed through the lower surface of the filter cake box 1 to drain the clear liquid filtered by the filter cake screen 10. It can be connected to the subsequent wastewater treatment pipeline or discharge system.

[0039] The tapping unit is installed on the filter cake box 1 and is used to tap the filter cake screen 10. The tapping unit is used to tap the filter cake screen 10 periodically or continuously to prevent the filter cake from clogging the filter screen pores, ensure the efficiency of liquid flow, and eliminate the need for frequent manual cleaning.

[0040] Several fixing plates 12 are fixedly installed on the side of the mounting frame 2. Fixing bolts 13 are threaded on the fixing plates 12. The side of the filter cake box 1 has a fixing thread groove for the fixing bolts 13 to be screwed in. By setting the fixing plates 12 on the side of the mounting frame 2, and using the fixing bolts 13 to cooperate with the fixing thread groove of the filter cake box 1, a stable connection between the two is achieved. Compared with welding, snap-fit ​​and other connection methods, threaded connection has the advantages of convenient disassembly, high connection strength and good reusability. When it is necessary to repair the moving unit, such as the power component 3, or replace the liquid delivery nozzle 8, the mounting frame 2 can be removed simply by unscrewing the fixing bolts 13, without damaging the equipment structure, thus reducing the difficulty of maintenance.

[0041] Several guide rods 15 are fixed on the surface of the filter cake box 1. The mounting frame 2 has guide holes for the guide rods 15 to pass through. A support ring 16 is fixedly installed on the outer surface of the guide rod 15. The support ring 16 is fitted to the lower surface of the mounting frame 2. The guide rod 15 and the guide hole of the mounting frame 2 form a guiding fit. During installation, the mounting frame 2 can be prevented from shifting, ensuring the accurate relative position of the mounting frame 2 and the filter cake box 1. The support ring 16 provides bottom support for the mounting frame 2, which can distribute the weight of the mounting frame 2 and the moving unit, preventing the mounting frame 2 from deforming or the fixing bolts 13 from loosening due to the force exerted solely on the fixing plate 12. At the same time, it reduces the direct friction between the mounting frame 2 and the filter cake box 1, extending the service life of the equipment.

[0042] The lifting frame 9 is threaded with several fixing bolts 17. The surface of the filter cake box 1 is provided with a fixing thread groove for the fixing bolts 17 to be screwed in. Through the cooperation of the fixing bolts 17 and the fixing thread groove, the lifting frame 9 can be quickly disassembled and installed. After long-term use, the filter cake screen 10 may have stubborn filter cake residue that is difficult to remove. At this time, the fixing bolts 17 can be unscrewed and the filter cake screen 10 can be directly removed from the filter cake box 1 through the lifting frame 9 for deep cleaning such as high-pressure washing, acid washing or replacement. The operation is convenient and does not affect other parts of the filter cake box 1.

[0043] The surface of the filter screen 10 is provided with a sealing groove, and a sealing ring 18 is embedded in the sealing groove. The sealing ring 18 is attached to the inner wall of the filter screen box 1. In traditional filter screen devices, there are often gaps between the filter screen 10 and the inner wall of the box, which causes unfiltered wastewater and filter screen mixture to leak directly from the gaps into the drain pipe 11, reducing the solid-liquid separation effect. The sealing ring 18 is preferably made of acid and alkali resistant rubber, which is suitable for the corrosive environment after the wastewater is neutralized and treated. It is embedded in the sealing groove of the filter screen 10 and fits tightly with the inner wall of the filter screen box 1 after installation. It can effectively seal the gaps and ensure that all wastewater must be filtered through the filter screen 10 before being discharged, thereby improving the filtration accuracy.

[0044] The striking unit includes a second power component 19 fixedly installed on the side of the filter cake box 1, a rotating shaft 20 rotatably installed on the filter cake box 1, several mounting sleeves 21 fixedly installed on the outer surface of the rotating shaft 20, several elastic rods 22 installed on the mounting sleeves 21, and striking balls 23 installed at the ends of the elastic rods 22. The output shaft of the second power component 19 is fixedly connected to the rotating shaft 20. The second power component 19 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the mounting sleeves 21 and elastic rods 22 to rotate synchronously, so that the striking balls 23 periodically strike the lower surface of the filter cake screen 10, shaking off the filter cake attached to the filter screen pores to avoid clogging. The elastic rods 22 have a certain elasticity and can buffer the impact force during striking to avoid rigid striking that causes deformation or damage to the filter cake screen 10. In this embodiment, the second power component 19 is specifically selected as a stepper motor.

[0045] When using

[0046] Feeding: The wastewater filter residue mixture generated after wastewater neutralization treatment is fed into the input via liquid conveying, and then sprayed out through the liquid conveying nozzle 8. The wastewater filter residue mixture falls into the filter residue box 1. At the same time, the power component 3 is started, and the power component drives the threaded rod 4 to rotate, which drives the mounting plate 5, the fixing block 6 and the liquid conveying pipe 7 to move at a constant speed along the axial direction of the threaded rod 4. This allows the wastewater filter residue mixture to fall into the box all over instead of falling into a fixed point. The residue is filtered and collected by the filter residue screen 10, and the liquid passes through the filter residue screen 10.

[0047] Anti-clogging tapping: During filtration and rinsing, the power component 29 is activated, driving the rotating shaft 20 to rotate. The elastic rod 22 drives the tapping ball 23 to periodically tap the lower surface of the filter screen 10, shaking off the filter residue clogging the filter screen pores and ensuring normal liquid penetration.

[0048] Drainage and Sludge Removal: Open the valve on the drain pipe 11 to drain the clear liquid at the bottom of the filter cake box 1. When the filter cake accumulates to a certain amount, close the feed and flushing. Unscrew the fixing bolt 13 to unlock and disassemble the mounting bracket 2. Unscrew the fixing bolt 2 17 and take out the filter cake screen 10 through the lifting bracket 9. Clean the trapped filter cake and reinstall it to complete one filter cake treatment cycle.
