Description

Technical Field

[0001] This utility model relates to the technical field of filter bags, and more specifically to a filter bag cleaning and recycling device. Background Technology

[0002] Currently, the most direct methods for disposing of used filter bags are landfill and incineration. Landfill is the most common method for handling used filter bags, but because the synthetic fibers used in filter bags have poor biodegradability, they are difficult to degrade naturally after being buried underground, forming permanent waste. In addition, long-term use in highly polluted environments such as thermal power plants and chemical plants results in filter bags having a large amount of heavy metals, toxic and harmful substances adhering to their surface, which will pollute the soil and water bodies when buried underground. Incineration is also an effective way to recycle used filter bags, using them as fuel to generate heat energy. However, the incineration process produces harmful substances such as carbon monoxide, aromatic hydrocarbons, and dioxins. Furthermore, used filter bags contain high-performance fibers such as PPS and P84, and direct incineration would be a serious waste of resources. Utility Model Content

[0030] See Figures 1 to 3 The present invention provides a filter bag cleaning and recycling device, which includes a high-pressure cleaning module 10, a reagent wetting module 20, a flexible cleaning module 30, a drying module 40 and a filter media decomposition module 50 in the order in which the filter bags are conveyed through.

[0031] The high-pressure cleaning module 10 is used to rinse the dirt off the filter bags;

[0032] The reagent wetting module 20 is used to wet the filter bag;

[0033] The flexible cleaning module 30 is used to clean the impregnated filter bags;

[0034] Drying module 40 is used to dry filter bags;

[0035] The filter media decomposition module 50 is used to crush and dry the filter bags.

[0036] When processing used filter bags, they sequentially pass through the high-pressure cleaning module 10, reagent wetting module 20, flexible cleaning module 30, drying module 40, and filter media decomposition module 50, ultimately becoming materials that can be used to support new filter bags. The movement path of the filter bags within the filter bag cleaning and recycling device (in each module) can be found in [reference needed]. Figure 4 Filter bags in Figure 4 The cleaning process is completed step by step along the path shown.

[0037] When it's time to start cleaning used filter bags, the filter bags to be processed need to be strung together in a long strip, with a rope tied to one end. The rope is then used to create a complete cleaning path within the module. The filter bag cleaning and recycling device is then started, allowing the filter bags to be conveyed along the predetermined cleaning path within the device. The filter bag cleaning path in this embodiment is as follows: Figure 4As shown, the filter bag moves along the trajectory indicated by the arrow in the filter bag cleaning and recycling device.

[0038] The high-pressure cleaning module 10 is used for the initial cleaning of the filter bags. It includes a high-pressure cleaning chamber 1, high-pressure nozzles 11 disposed within the chamber, and a conveying assembly. The conveying assembly can be a first conveying roller 12, which is used to move the filter bags within the high-pressure cleaning chamber 1. Slide rails 13 are provided on both sides of the conveying assembly along the conveying direction. The high-pressure nozzles 11 are slidably mounted on the slide rails 13, meaning they are distributed along both sides of the conveying assembly. Each high-pressure nozzle includes a high-pressure nozzle for air jets and a high-pressure nozzle for water jets, used to blow air onto the filter bags. Preferably, the sliding speed of the high-pressure nozzles 11 on the slide rails 13 can be controlled.

[0039] Waste filter bags enter the high-pressure cleaning chamber through the inlet of the high-pressure cleaning module 10 and are conveyed by the first conveyor roller 12. High-pressure nozzles distributed on both sides of the first conveyor roller 12 move up and down on the slide rail 13. The high-pressure nozzles 11 first spray air and then water to remove dirt from the filter bags. The movement of the high-pressure nozzles 11 is one up and one down as one cycle. Preferably, the filter bags must go through at least 3 cycles during high-pressure cleaning.

[0040] After high-pressure cleaning, the filter bags will enter the reagent wetting module 20. The reagent wetting module 20 includes a solution storage chamber 2, a second conveyor roller 21, a cleaning assembly (which can be a movable brush, not shown in the figure), and a squeezing assembly (which is located at the channel opening between the solution storage chamber 2 and the flexible cleaning chamber 3 and is used to squeeze the wetting filter bags to remove moisture from them; this is prior art, not shown in the figure). The second conveyor roller 21 is used to move the filter bags within the solution storage chamber 2. The cleaning assembly is used to remove stubborn dirt from the inner and outer surfaces of the filter bags after wetting. The squeezing assembly is used to remove as much solution as possible from the filter bags, reducing the time the filter bags spend in the drying chamber 4. Specifically, the solution storage chamber 2 is filled with reagents, which can be acidic or alkaline solutions, detergents, bleaching agents, or modified solutions. The reagents can be replaced according to actual needs to neutralize and soften harmful and polluting substances on the filter bags, bleach, clean, improve the performance of the filter bags, and remove adhering acidic or alkaline substances. In this embodiment, the second conveyor rollers 21 are arranged in three rows in the solution storage chamber 2. The time for the filter bags to enter the solution storage chamber 2 for immersion is controlled by the second conveyor rollers 21. The time the filter bags spend in the reagents can be controlled by controlling the rotation speed of the second conveyor rollers 21. After the expected immersion is achieved, the filter bags are put into the next module for processing.

[0041] Next, the soaked filter bags enter the flexible cleaning module 30 for secondary cleaning. The flexible cleaning module 30 includes a flexible cleaning chamber 3, and spray nozzles 31, brush plates 32, and a third conveyor roller 33 disposed within the flexible cleaning chamber 3. The brush plates 32 include multiple brushes located on both sides of the third conveyor roller 33. The filter bags enter the flexible cleaning chamber 3 and are conveyed and moved by the third conveyor roller 33. At this time, the multiple brushes on the brush plates 32 perform friction cleaning on the filter bags (guide rails can be provided on the brush plates 32, and the brushes move up and down along the guide rails to brush the filter bags). During this process, the spray nozzles 31 are activated intermittently to spray air, thereby subjecting the filter bags to intermittent vibration and impact to improve the overall cleaning effect.

[0042] The difference between using the flexible cleaning module 30 for secondary cleaning and using the high-pressure cleaning module 10 for primary cleaning is that the purpose of primary cleaning is to remove large stains and easily cleanable stains on the filter bag, while the purpose of secondary cleaning is to clean the stains missed during the primary cleaning and to treat the softened stubborn stains on the filter bag after being soaked by the reagent soaking module 20.

[0043] After the secondary cleaning is completed, the filter bags enter the drying module 40 for drying. The drying module 40 includes a drying chamber 4, a heating component 41 and a fourth conveyor roller 42 located in the drying chamber 4. The heating component 41 is located in the center of the drying chamber 4, and the fourth conveyor roller 42 drives the filter bags to move around inside the drying chamber 4. At the same time, the heating device is activated to heat and dry the filter bags at high temperature to remove excess moisture. By placing the heating component 41 in the center of the drying chamber 4, the filter bags moving around can be heated and dried more evenly.

[0044] Finally, the dried filter bags enter the filter media decomposition module 50. The filter media decomposition module 50 includes a filter media decomposition chamber 5, and a crushing component 51 and a loosening component 52 located within the chamber 5. The crushing component 51 is used to crush the filter bags dried by the drying module 40, and the loosening component 52 is used to loosen the filter bags. Both the crushing component 51 and the loosening component 52 are existing structures and will not be described in detail here. The loosening component 52 can be a loosening machine; loosening means using the loosening machine to decompose the filter bags back into raw materials, allowing the filter bags to be reused for manufacturing. After being processed by the filter media decomposition module 50, the filter bags can be used as raw materials for the production of new filter bags, improving material utilization and avoiding waste.

[0045] By adopting the above solution, the filter bag cleaning and recycling device of this utility model can perform initial cleaning, soaking, secondary cleaning, drying and crushing operations on the filter bags. It can recycle and reuse the processed and crushed filter bags to produce new filter bags. Moreover, the processed filter bags can reduce pollutants. Thus, this utility model solves the problem of reusing conventional filter bags after use, improves material utilization, reduces filter bag manufacturing costs, and is more environmentally friendly.

[0046] It should be noted that channels are provided between the above modules to allow the filter bags to be conveyed through. For some cleaning steps involving liquids, such as the high-pressure cleaning module 10, reagent wetting module 20, and flexible cleaning module 30, these devices are equipped with independent inlets and outlets to ensure that the water level in the module is lower than the height of the channel between it and other modules, so that liquid will not flow uncontrollably into other modules in large quantities along the channel.

[0047] The first conveyor roller 12, the second conveyor roller 21, the third conveyor roller 33, and the fourth conveyor roller 42 mentioned above are the conveying devices in this filter bag cleaning and recycling device. The filter bags are conveyed by these conveyor rollers according to... Figure 4 The conveyor rollers move along the indicated path. Preferably, these conveyor rollers can be replaced by other devices or conveyor components that can be installed within the module and have a conveying function. The conveyor components can also be connected to electronic equipment or knobs for manual and electric control of the conveying speed. Regarding the specific method of controlling the conveying speed, taking the above embodiment as an example, each conveyor roller is controlled by a separate motor. These motors are electrically connected to the same circuit board or controller, thereby allowing individual control of each conveyor roller or simultaneous control of all motors.

[0048] The position of the aforementioned conveyor rollers can be flexibly adjusted and set in different positions within each module according to the specific path requirements for cleaning the filter bags.

[0049] Preferably, the high-pressure cleaning module 10, reagent wetting module 20, flexible cleaning module 30, drying module 40 and filter media decomposition module 50 are integrated on the same device, and the structure within each module is not limited to the above-mentioned structure, as long as it can achieve the purpose of the corresponding module.

[0050] The above is merely one embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
