Description

Technical Field

[0001] This utility model relates to the field of liquid filter technology, and in particular to a sloping trough type continuous unloading strong magnetic automatic liquid filter. Background Technology

[0002] In today's industrial production, various industrial production lines often discharge large amounts of industrial wastewater containing tiny ferromagnetic suspended solids (such as iron filings). These tiny ferromagnetic suspended solids must be filtered out using high-efficiency liquid filters in order to reuse and recycle this industrial wastewater or to discharge it in compliance with national environmental protection standards.

[0003] Currently, filters used to perform the above-mentioned ferromagnetic solid-liquid separation are mainly divided into two categories: the first category is bag-type liquid filters that require frequent manual replacement of filter bags; the second category is permanent magnet tube-type automatic liquid filters with self-cleaning and automatic sewage discharge capabilities.

[0004] While the aforementioned bag-type liquid filters are simple in structure and inexpensive, the frequent shutdowns, disassembly, and manual replacement of filter bags inevitably incur significant labor and material costs for maintenance. Furthermore, they severely disrupt production line operations, causing substantial downtime and significantly reducing overall plant efficiency. The removed filter bags also carry large amounts of sludge and other solid contaminants, leading to serious secondary pollution and environmental treatment costs, making it difficult for the workshop to meet and maintain "5S" production standards. While self-cleaning and automatic sludge discharge capabilities of permanent magnet rod sleeve-type automatic liquid filters significantly avoid the main drawbacks of bag-type liquid filters, after a prolonged period of automatic operation, scale will form on the outer wall of the permanent magnet sleeve, creating a firmly hardened, high-magnetic-resistance scale layer. Because the filter element does not receive timely self-cleaning, it frequently operates in a state of low efficiency and high magnetic resistance. Furthermore, the sludge discharge volume corresponding to the unit solids filtration volume is large, with low sludge concentration. The filtered viscous, slurry-like solids are unsuitable for direct discharge and require complex dewatering treatment, thus significantly impacting subsequent wastewater treatment processes and greatly increasing the overall production cost. In addition, the permanent magnet rod sleeve-type automatic liquid filters used in modern industrial production require complex hydraulic drive and automatic control systems. The equipment is complex, expensive, and has low reliability. The need for intermittent sludge discharge also results in low overall filtration efficiency. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of existing technologies, which mainly use bag-type liquid filters and permanent magnet rod sleeve-type automatic liquid filters to filter industrial wastewater containing tiny ferromagnetic suspended solids. However, bag-type liquid filters require frequent shutdowns for manual disassembly and replacement of filter elements, and cannot maintain long-term maintenance-free online automatic operation. On the other hand, permanent magnet rod sleeve-type automatic liquid filters have low filtration efficiency, complex and delicate internal structure, high cost, and poor online stability and reliability. They require frequent periodic shutdowns for manual disassembly and cleaning, and the complex permanent magnet sleeve is difficult to clean due to scale buildup. The viscous solid slurry discharged also requires complex dehydration and drying treatment, resulting in complex production processes, high costs, and the ability to only achieve intermittent feeding and unloading. The control system is also complex, and the overall working efficiency is low.

[0006] To solve the above-mentioned technical problems, this utility model provides a chute-type continuous discharge strong magnetic automatic liquid filter, comprising,

[0007] frame;

The strong magnet is disposed inside the conveyor belt, and multiple baffles are spaced apart on the outside of the conveyor belt. The drive source is used to drive the active roller to rotate.

[0013] In one embodiment of the present invention, the belt separator further includes two guide rollers symmetrically arranged on the support and located on the side away from the self-flowing trough, the two guide rollers tightly supporting the conveyor belt.

[0014] In one embodiment of this utility model, the belt separator further includes a vibrating mechanism, which includes a static support, a moving support, a spring, a vibrator, and vibrating rollers. The static support is disposed inside the conveyor belt and located on the side close to the solid material hopper. The moving support is movably connected to the static support. The spring is connected between the moving support and the static support. The vibrator is mounted on the moving support, and two vibrating rollers are disposed on the moving support between it and the conveyor belt on the side close to the solid material hopper. The vibrating rollers press tightly against the conveyor belt.

[0015] In one embodiment of this utility model, the vibrator is a vibration motor, an electromagnetic vibrator, or a pneumatic vibrator.

[0016] In one embodiment of this utility model, a tangential guide plate is arranged parallel to the medium inlet in the self-flowing tank.

[0018] In one embodiment of this utility model, one side of the self-flowing channel is bent in an L-shape to form the overflow channel.

[0019] In one embodiment of the present invention, an overflow buffer tank is further included. The overflow buffer tank is disposed at the end of the overflow tank with a lower height, and a return port is provided on the overflow buffer tank.

[0020] In one embodiment of this utility model, valves are provided on the medium inlet, the filtrate outlet, the discharge port, and the return port.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0031] Reference Figures 1-5 As shown, this utility model discloses a chute-type continuous discharge strong magnetic automatic liquid filter, comprising:

[0032] Rack 1;

[0033] Belt separator 2, which is inclinedly mounted on frame 1;

[0034] The self-flowing trough 3 is installed on the frame 1 parallel to the belt separator 2 and located between the belt separator 2 and the frame 1. The higher end of the self-flowing trough 3 is provided with a medium inlet 31, and the bottom of the self-flowing trough 3 is provided with multiple normal guide plates 32 arranged at intervals along its length. The end of each normal guide plate 32 away from the medium inlet 31 is bent toward the belt separator 2.

[0035] The filtrate buffer tank 4 is located near the lower end of the gravity flow tank 3, and the filtrate buffer tank 4 is provided with a filtrate outlet 41.

[0036] Solid material discharge hopper 5 is located near the higher end of belt separator 2, and a discharge port 51 is provided on the solid material discharge hopper 5.

[0037] Specifically, during the equipment start-up preparation state, the valve on the medium inlet 31 is closed, while the valves on the filter liquid outlet 41, discharge port 51, and return port 81 are opened; then the belt separator 2 is started; next, the valve on the medium inlet 31 is opened, allowing the solid-liquid two-phase medium containing iron-containing magnetic suspended solid particles with an appropriate static pressure head to be input into the gravity flow tank 3 at an appropriate flow rate. The solid-liquid two-phase medium flows from top to bottom along the gravity flow tank 3. When the flowing two-phase medium passes through the normal guide plate 32, due to the guiding effect of the curved part at the front end of the normal guide plate 32, the two-phase medium will move towards the belt separator located obliquely above it. As the bottom surface of the conveyor belt 24 of the device 2 moves, the upward-rising fluid surges carrying a large amount of ferromagnetic solid suspended matter continuously wash over the bottom surface of the running conveyor belt 24. The ferromagnetic solid suspended matter in the fluid is captured by the magnetic field generated by the strong magnet 25 of the belt separator 2, and the ferromagnetic solid suspended matter is firmly adsorbed onto the running conveyor belt 24. In this way, the fluid medium input into the gravity flow tank 3 is completely free of ferromagnetic solid particles, becoming a clean ferromagnetic filtrate, and continuously enters the filtrate buffer tank 4 set at the bottom of the gravity flow tank 3, and is finally discharged from the equipment through the filtrate discharge port 41. Simultaneously, as the ferromagnetic solid material adsorbed on the conveyor belt 24 moves upward with the conveyor belt 24 and is about to exceed the top of the strong magnet 25, the strong magnet 25 at this point has a large upward-sloping chamfer, which forms a gradually increasing air gap. This causes the magnetic resistance to continuously increase, thereby gradually weakening the effective magnetic field strength of the ferromagnetic solid material adsorbed on the conveyor belt 24 and gradually reducing the adsorption force. This is conducive to the gradual demagnetization and self-unloading of the ferromagnetic solid material adsorbed on the conveyor belt 24, reducing its slippage and accumulation on the conveyor belt 24. Finally, when the conveyor belt 24 completely detaches from the top of the strong magnet 25 carrying the ferromagnetic solid material originally magnetically adsorbed on it, the ferromagnetic solid material on the conveyor belt 24 is completely demagnetized, becomes loose, and falls in large quantities into the solid material hopper 5 below. Finally, it is discharged from the equipment through the discharge port 51. Thus, the continuous and stable feeding and continuous self-unloading process of this filter is completed.

[0038] Specifically, multiple baffles 27 spaced apart on the bottom surface of the conveyor belt 24 are used to propel the ferromagnetic solid material trapped on the bottom surface of the conveyor belt forward. When the ferromagnetic solid material is about to leave the magnetic field control range of the strong magnet 25 as the conveyor belt moves forward, without the baffles 27, the ferromagnetic solid material would slide continuously along the bottom surface of the conveyor belt 24 in the opposite direction of the conveyor belt's movement towards the strong magnet 25. If this happens, the ferromagnetic solid material on the bottom surface of the conveyor belt will not be able to be discharged normally, but will instead continue to gather and accumulate at the top of the strong magnet 25. The multiple baffles 27 spaced apart along the bottom surface of the conveyor belt 24 prevent this long-distance sliding of the ferromagnetic solid material on the bottom surface of the conveyor belt 24, allowing it to slide only a very small distance (the maximum sliding distance is the distance between two adjacent baffles on the bottom surface of the conveyor belt), and always manage to leave the magnetic field control range of the strong magnet 25 in time and fall smoothly into the discharge hopper 5 below for timely discharge.

[0039] It is conceivable that, in the above process, as long as we appropriately design and adjust the linear speed of the conveyor belt 24, the self-flowing static pressure head of the medium entering the medium inlet 31, the length and tilt angle of the self-flowing trough 3, the number, shape, length and tilt angle of the normal guide plates 32, and the length and magnetic field strength of the strong magnet 25 according to the particle size and concentration of the ferromagnetic solids contained in the fluid medium, we can always ensure that all the ferromagnetic solids contained in the fluid medium are adsorbed on the bottom surface of the continuously and stably moving conveyor belt 24, thereby completely filtering and removing the ferromagnetic solids from the liquid medium.

[0040] This utility model discloses a chute-type continuous discharge strong magnetic automatic liquid filter, which features advanced working principles and technical characteristics. It boasts a simple, stable, and reliable structure, enabling continuous feeding and unloading operations. It achieves extremely high filtration efficiency and minimal wastewater flow, realizing near-dry solid-liquid separation of ferromagnetic solids. This significantly improves filtration efficiency, substantially reduces production costs, and ensures long-term stable, maintenance-free, reliable, and efficient operation. It greatly reduces manual maintenance costs, minimizes downtime for disassembly and maintenance, and significantly improves production line efficiency. This chute-type continuous discharge strong magnetic automatic liquid filter is suitable for ferromagnetic solid-liquid separation processes involving ferromagnetic solid-liquid two-phase process media in various industrial production lines. It is also suitable for filtering industrial wastewater containing minute ferromagnetic suspended solids discharged from various industrial production lines, allowing for direct recycling or environmentally compliant discharge, thus promoting green and environmentally friendly production methods.

[0041] Reference Figure 1 and Figure 3As shown, the belt separator 2 further includes a support 21, an active roller 22, a passive roller 23, a conveyor belt 24, a strong magnet 25, and a drive source 26. The support 21 is connected to the frame 1. The active roller 22 and the passive roller 23 are rotatably connected to the support 21 and connected through the conveyor belt 24. The strong magnet 25 is disposed inside the conveyor belt 24, and multiple baffles 27 are spaced apart on the outside of the conveyor belt 24. The drive source 26 is used to drive the active roller 22 to rotate.

[0042] Furthermore, the belt separator 2 also includes two guide rollers 28 symmetrically arranged on the support 21 and located on the side away from the gravity flow channel 3, with the two guide rollers 28 tightly supporting the conveyor belt 24.

[0043] Reference Figure 5 As shown, the belt separator 2 further includes a vibrating mechanism 29, which includes a static support 291, a moving support 292, a vibrator 293, a vibrating drum 294, and a spring 295. The static support 291 is located inside the conveyor belt 24 and on the side close to the solid material hopper 5. The moving support 292 is movably connected to the static support 291. A spring connects the moving support and the static support. The vibrator 293 is mounted on the moving support 292. Two vibrating drums 294 are provided on the moving support 292 between it and the conveyor belt 24 on the side close to the solid material hopper 5. The vibrating drums 294 press tightly against the conveyor belt 24. Specifically, fine, wet ferromagnetic solids may physically interlock and agglomerate with each other. Even if they are completely demagnetized, they may not be able to completely detach from the bottom surface of the stably operating conveyor belt 24 in time, thus failing to fall cleanly into the solid material hopper 5. Some ferromagnetic solids are carried away by the conveyor belt 24 and scattered to other parts of the equipment. To prevent this from happening, the belt separator 2 is also designed with a vibrating mechanism 29. The vibrating mechanism 29 is located inside the conveyor belt 24 directly above the solid material hopper 5. When the vibrating mechanism 29 is running, the vibrating drum 294 will vibrate up and down at high frequency under the high-frequency vibration of the vibrator 293, thereby causing the section of the conveyor belt 24 that it contacts to vibrate up and down at high frequency. This ensures that all the ferromagnetic solids remaining on the conveyor belt 24 can fall into the solid material hopper 5 in time and be completely discharged out of the equipment.

[0044] Furthermore, the vibrator 293 adopts a vibrating motor, an electromagnetic vibrator, or a pneumatic vibrator.

[0045] Reference Figure 1 , Figure 2 and Figure 4As shown, furthermore, a tangential guide plate 6 is arranged parallel to the medium inlet 31 in the gravity flow channel 3. It can be imagined that when the solid-liquid two-phase medium is input from the medium inlet 31, the fluid medium will initially flow upward from the top and bottom of the gravity flow channel 3. The tangential guide plate 6 can play a guiding role, so that the solid-liquid two-phase medium moves from top to bottom along the gravity flow channel 3.

[0046] Furthermore, it also includes an overflow trough 7, which is connected to the frame 1 parallel to the gravity flow trough 3. The overflow trough 7 is arranged side by side on one side of the gravity flow trough 3 and communicates with it. The bottom of the overflow trough 7 is higher than the bottom of the gravity flow trough 3 but lower than the bottom of the strong magnet 25. Specifically, in order to prevent the conveyor belt 24 and the strong magnet 25 above the gravity flow trough 3 from being submerged due to the excessive liquid level of the solid-liquid dual-phase medium in the gravity flow trough 3, an overflow trough 7 is arranged parallel to it on one side of the gravity flow trough 3. The bottom of the overflow trough 7 is higher than the bottom of the gravity flow trough 3 but lower than the bottom of the conveyor belt 24 and the strong magnet 25. In this way, all solid-liquid dual-phase medium flowing into the overflow trough 7 will flow into the overflow buffer tank 8 arranged below it, and then return to the original storage tank of the solid-liquid dual-phase medium by gravity through the return port 81 on the overflow buffer tank 8.

[0047] Furthermore, one side of the self-flow channel 3 is bent into an L-shape to form an overflow channel 7.

[0048] Furthermore, it also includes an overflow buffer 8, which is located at the lower end of the overflow 7, and has a return port 81.

[0049] Furthermore, valves are installed on the medium inlet 31, the filtrate outlet 41, the discharge port 51, and the return port 81.

[0050] As another, more specific embodiment, the following supplementary explanation is provided:

[0051] Considering that the flow velocity of the solid-liquid dual-phase fluid in the gravity flow tank 3 continuously increases as it flows from top to bottom, while the flow rate of the solid-liquid dual-phase fluid flowing through each cross-section from top to bottom remains constant, and furthermore, the ferromagnetic solid components contained in the solid-liquid dual-phase fluid are continuously removed as it flows from top to bottom along the bottom of the gravity flow tank 3, the actual liquid level height of the solid-liquid dual-phase fluid continuously decreases as it flows from top to bottom along the bottom of the gravity flow tank 3. Therefore, it is necessary to set up a manual fine-tuning mechanism for the belt separator 2 for its actual installation height and installation angle, so as to be suitable for different flow rates and velocities, and to always ensure that the bottom surface of the iron removal adsorption conveyor belt of the belt separator 2 is always along the actual liquid level of the solid-liquid dual-phase fluid in the gravity flow tank 3, and is set parallel and operates stably at an appropriate height above the actual liquid level.

[0052] Furthermore, it is necessary to manufacture the cross-sectional area (height) of the gravity flow channel 3 into a variable cross-section structure that gradually decreases from top to bottom. The specific structural parameters of the variable cross-section need to be rationally designed and determined based on fluid data and actual process test data.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
