Description

Technical Field

[0001] This utility model relates to the field of filtration equipment cleaning technology, and in particular to a cleaning component for plate and frame filters. Background Technology

[0002] Plate and frame filters, widely used in various industries for solid-liquid separation, play a crucial role in fields such as chemical, pharmaceutical, and food processing. Their core function is to effectively trap solid particles in liquids through the filter frame assembly, thereby purifying or concentrating the liquid. However, with prolonged use, the filter frame surface is prone to clogging due to the continuous accumulation of solid particles. This directly affects the filter's efficiency and, in severe cases, may even cause the equipment to malfunction. Therefore, to ensure stable equipment performance and extend its service life, regular and thorough cleaning of the filter frames is an indispensable maintenance step.

[0003] In current practice, the cleaning of plate and frame filters mainly relies on manual disassembly and cleaning or simple automatic flushing systems. While manual cleaning allows direct contact with the filter frames, the process is not only time-consuming and labor-intensive but also carries the risk of damaging the filter frames due to improper operation, which undoubtedly negatively impacts the overall performance of the equipment. Existing automatic flushing systems, while reducing manual labor intensity to some extent, primarily use continuous water flow or low-pressure cleaning methods, often resulting in unsatisfactory cleaning effects, especially for highly adhesive or small-sized impurities, which these systems often struggle to remove completely. Furthermore, traditional cleaning methods typically lack specificity, failing to adjust the cleaning intensity and frequency according to the actual clogging condition of the filter frames. This not only wastes water and energy resources but may also fail to achieve the desired cleaning results. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning component for plate and frame filters.

[0005] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0006] A cleaning assembly for a plate and frame filter press includes a high-frequency pulse water supply assembly and a washing filter frame assembly. The drain end of the high-frequency pulse water supply assembly is connected to the inlet end of the washing filter frame assembly, and the washing filter frame assembly is located at the outlet end of the filter assembly of the plate and frame filter press.

[0007] Furthermore, the high-frequency pulse water supply assembly includes an over-aeration generator, a washing liquid, and a high-frequency pulse generator. The inlet of the over-aeration generator is connected to a container holding the washing liquid, and the outlet of the washing liquid and the outlet of the high-frequency pulse generator are simultaneously connected to the inlet of the washable filter frame assembly.

[0008] Furthermore, a washing liquid heat exchanger is provided between the outlet of the washing liquid and the inlet of the washing filter frame assembly.

[0009] Specifically, the washing filter assembly includes a filter frame, a sieve plate, a washing pipe, a sieve plate support column, and washing nozzles. The sieve plate consists of two pieces, with multiple sieve plate support columns positioned between the two sieve plates. The washing pipe is located in the gap between the two sieve plates, and multiple washing nozzles are evenly distributed on the washing pipe. The inlet of the washing pipe is connected to the washing water outlet of the washing liquid heat exchanger. The sieve plate, washing pipe, sieve plate support column, and washing nozzles are fixedly installed inside the filter frame, and the filter assembly is installed on the outside of the sieve plate.

[0010] The working principle of this utility model is as follows:

[0011] High-pressure air is injected into the washing liquid container through an ultra-aeration generator to generate a mixture of high-pressure air and washing liquid. A high-frequency pulse generator receives the mixture of high-pressure air and washing liquid from the ultra-aeration generator and converts it into a high-frequency pulse cleaning liquid. The high-frequency pulse cleaning liquid is transported to the washing pipe through a pipeline, and then multiple nozzles on the washing pipe rinse the back of the sieve plate. The high-frequency pulse cleaning liquid passes through the sieve plate to rinse the filter cloth, washing the filter cake off the filter cloth, which facilitates the removal of the filter cake. The temperature of the washing liquid is adjusted by the washing liquid heat exchanger as needed to achieve high-frequency pulse temperature-variable washing, further improving the cleaning efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention achieves highly efficient cleaning of the filter frame surface of a frame filter press by combining a high-frequency pulse water supply component and a washing-type filter frame component. The high-frequency pulse water supply component utilizes a pressure fluctuation device to generate a cleaning fluid with high-frequency pulses, which significantly enhances the impact force of the cleaning fluid and thus greatly improves cleaning efficiency. Furthermore, by introducing a cleaning fluid heat exchanger, the temperature of the cleaning fluid can be dynamically adjusted according to the characteristics of the dirt, thereby further optimizing the cleaning effect and reducing energy consumption.

[0014] In summary, this invention solves the problems of low cleaning efficiency, poor cleaning effect, and resource waste in the existing technology, and provides a more intelligent and efficient solution for cleaning filters. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] like Figures 1-4 As shown, this utility model provides a cleaning assembly for plate and frame filters. Its core lies in the coordinated operation of a high-frequency pulse water supply assembly and a washing-type filter frame assembly to achieve efficient and intelligent cleaning of the filter. The high-frequency pulse water supply assembly consists of an over-aeration generator 1, a washing liquid container 2, and a high-frequency pulse generator 11. The over-aeration generator 1 is connected to the washing liquid container 2 via a pipe and injects high-pressure gas into the washing liquid in the washing liquid container 2 through a micro-orifice nozzle to form a gas-liquid mixture. The washing liquid stored in the washing liquid container 2 contains a specific proportion of surfactants, which can effectively dissolve dirt and enhance the cleaning effect. The high-frequency pulse generator 11 receives the gas-liquid mixture from the over-aeration generator 1 through a delivery pipe and, under the action of a pressure fluctuation device installed inside, converts the gas-liquid mixture into a high-frequency pulse cleaning liquid. The high-frequency pulse cleaning liquid is then transported to the washing-type filter frame assembly through a pipe to complete the cleaning operation.

[0022] The washable filter assembly includes a filter frame 6, a sieve plate 7, a wash pipe 9, sieve plate support columns 10, and wash nozzles 12. Two sieve plates 7 are fixedly connected by multiple sieve plate support columns 10 to form a stable structural gap. The wash pipe 9 is located in the gap between the two sieve plates 7. Multiple wash nozzles 12 are evenly distributed on the wash pipe 9, with their outlets facing inwards towards the sieve plates 7 for direct rinsing of the back of the sieve plates 7. The inlet of the wash pipe 9 is connected to a high-frequency pulse water supply assembly via a washing liquid heat exchanger 3, ensuring that the cleaning liquid is evenly distributed to each wash nozzle 12.

[0023] A washing liquid heat exchanger 3 is installed on the pipeline between the washing liquid container 2 and the washing pipe 9. The inlet of the heat exchange chamber is connected to the outlet of the washing liquid container 2, and the outlet is connected to the inlet of the washing pipe 9. Through the above structural design, the washing liquid heat exchanger 3 can adjust the temperature of the washing liquid according to the characteristics of the dirt to optimize the cleaning effect. For example, when the dirt contains grease, appropriately increasing the temperature of the washing liquid can accelerate the dissolution of grease, thereby significantly improving the cleaning efficiency.

[0024] The working process of the high-frequency pulse water supply component is as follows:

[0025] The over-exposure generator 1 introduces high-pressure gas from an external air source and injects the gas into the washing liquid container 2 through a micro-orifice nozzle to form a gas-liquid mixture.

[0026] The gas-liquid mixture enters the high-frequency pulse generator 11 through the delivery pipeline. The high-frequency pulse generator 11 generates high-frequency pulse cleaning fluid by periodically changing the pressure inside the cavity to cause the pressure of the gas-liquid mixture to oscillate rapidly.

[0027] The high-frequency pulse cleaning fluid is delivered to the washing pipe 9 through a pipeline and sprayed onto the surface of the screen plate 7 via the washing nozzle 12 to complete the cleaning operation of the filter frame 6. During this process, the high-frequency pressure fluctuation of the high-frequency pulse cleaning fluid enhances the water flow impact force, thereby significantly improving the cleaning efficiency.

[0028] The outer side of the filter frame 6 in the washable filter assembly is equipped with a filter element, which includes a filter cloth 5 and a filter cake 8. The filter cloth 5 is tightly attached to the outer surface of the sieve plate 7 to trap solid particles in the liquid. The filter cake 8 adheres to the surface of the filter cloth 5 and gradually thickens over time. When the filter cake 8 reaches a preset thickness, the high-frequency pulse water supply component is activated to backwash the filter cloth 5 and the filter cake layer with high-frequency pulse cleaning fluid. After passing through the sieve plate 7, the high-frequency pulse cleaning fluid acts on the surface of the filter cloth 5 in the form of a high-speed jet, causing the filter cake layer to detach from the surface of the filter cloth 5 for easy removal. This process achieves efficient cleaning of the surface of the filter cloth 5 while avoiding the time-consuming and labor-intensive problems associated with manual disassembly and cleaning.

[0029] In practical applications, this cleaning component significantly improves the cleaning efficiency of frame filters and reduces resource waste. Furthermore, the high-frequency pulse cleaning fluid, with its powerful impact and wide coverage, exhibits significantly better cleaning results than traditional continuous water flow or low-pressure cleaning methods, especially for highly adhesive or small-particle impurities. By introducing a cleaning fluid heat exchanger, the temperature of the cleaning fluid can be dynamically adjusted according to the characteristics of the dirt, further optimizing the cleaning effect and reducing energy consumption.

[0030] This utility model features a compact and highly stable overall structural design. The frame structure 4 houses multiple vertically arranged filter frames 6 for multi-layer filtration. Each filter frame 6 contains multiple horizontal baffles, forming evenly distributed filtration channels to ensure uniform water flow between layers and complete coverage of the filter frame 6 surface. The surface of the filter frame 6 has evenly distributed perforations; these perforations allow water to fully contact the surface and remove dirt. A supporting frame surrounding the filter frame 6 surface enhances its overall strength. The supporting structure 8, located outside the frame, provides additional mechanical strength and stability to the entire washing filter assembly, ensuring stable operation under high-pressure water flow.

[0031] In summary, this invention achieves highly efficient cleaning of the filter frame surface of a frame filter press through the coordinated operation of a high-frequency pulse water supply component and a washing-type filter frame component. The high-frequency pulse water supply component generates high-frequency pulse cleaning fluid through a pressure fluctuation device, enhancing the impact force of the cleaning fluid and thus significantly improving cleaning efficiency. Furthermore, by introducing a washing fluid heat exchanger, the temperature of the washing fluid can be dynamically adjusted according to the characteristics of the dirt, further optimizing the cleaning effect and significantly reducing energy consumption. This cleaning component effectively solves the problems of low cleaning efficiency, poor results, and resource waste in existing technologies, providing a more intelligent and efficient solution for cleaning frame filters.

Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
