Description

Technical Field

[0001] This utility model belongs to the technical field of filtration and concentrator technology, specifically, it relates to a fully automatic rotary disc type concentration and filtration device. Background Technology

[0002] Currently, there are many types of filters used in production, including filter presses, separators, thickeners, and settling tanks. Filter thickeners are widely used in metallurgy, mining, coal, chemical, building materials, and environmental protection sectors to treat sludge, wastewater, and waste residue. They are of great significance for improving the utilization rate of recycled water, the concentration of underflow, and environmental protection. However, during filtration, a large amount of raw material adheres to the inside of the filter thickener, which is difficult to clean. Therefore, it is necessary to improve the internal structure of the filter thickener. In the market, thickeners have a large amount of concentrated raw material attached to the filter disc, making it difficult for workers to clean the inside. Some devices even require disassembly for cleaning. During cleaning, the residual odor of the concentrated raw material is quite strong, affecting the efficiency of the cleaning work. Sometimes, the cleaning is not thorough, which affects the normal production of the thickener. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] like Figure 1 As shown, this utility model provides a fully automatic rotary disc-type concentration and filtration device, including a filtration section and a support section. The filtration section includes: a filter cylinder 15, which is provided with a feed inlet 2, a discharge outlet 3, and a cleaning liquid inlet 1; a disc-type filter assembly is disposed inside the filter cylinder 15, including a plurality of vertically aligned and spaced filter discs 11; a cleaning pipe 4 is disposed inside the filter cylinder 15 for cleaning the disc-type filter assembly, the cleaning pipe 4 is connected to a spray rinsing pipe 12, the inlet of the cleaning pipe 4 is connected to the cleaning liquid inlet 1, and the cleaning liquid flows from the cleaning pipe 4 to the spray rinsing pipe 12, which is disposed on the filter discs 11; a feed pipe system is disposed inside the filter cylinder 15, including a feed pipe 5, which includes one inlet and multiple outlets, the inlet of the feed pipe 5 is connected to the feed inlet 2, and each of the filter discs 11 has an outlet of the feed pipe 5 above it, and the filtrate flows from the outlet of the feed pipe 5 to the filter disc 11.

[0034] Furthermore, the support unit includes a base frame 8, on which a support leg 9 is provided. One end of the support leg 9 is connected to the base frame 8, and the other end of the support leg 9 is connected to the filter unit. The base frame 8 is provided with a drive assembly, which includes a main rotating shaft 6, a motor, and a reducer. The motor can be an explosion-proof motor. The motor is connected to the reducer, and the main rotating shaft 6 is connected to the reducer. The main rotating shaft 6 is located inside the filter cartridge 15, and a disc filter assembly is sleeved on the main rotating shaft 6. A connector is provided on the disc filter assembly, and the main rotating shaft 6 and the disc filter assembly are fixedly connected by the connector. The direct-drive transmission method of the motor has advantages over the hydraulic drive method, such as high transmission efficiency, low noise, high reliability, long fault-free operation time, and long service life. It is also easier to realize remote speed adjustment function.

[0035] Furthermore, a mechanical seal is provided on the main rotating shaft 6, and a sealing fluid is provided between the two end faces of the mechanical seal. The pressure of the sealing fluid is higher than the working pressure inside the filter cartridge 15.

[0036] Furthermore, a stirrer 7 is provided on the main rotating shaft 6. The stirrer 7 is positioned above the disc filter assembly, which is beneficial for filtrate filtration.

[0037] Furthermore, the base frame 8 is equipped with an isolation pump station 10. There are at least two isolation pump stations 10. When one pump station fails and needs to be repaired, the other pump can work normally without affecting the normal operation of the entire set of equipment.

[0038] Furthermore, the isolation pump station 10 is connected to the mechanical seal device. The isolation pump station 10 is equipped with an alarm device. The isolation pump station 10 provides good lubrication and cooling for the mechanical seal device, enabling it to operate under ideal working conditions and effectively extending the fault-free operation cycle of the mechanical seal device. The pump station performs real-time monitoring of the flow rate, pressure, and temperature of the flushing isolation fluid system for each mechanical seal device. When the mechanical seal device malfunctions, the friction on its end face causes an abnormal temperature rise. The temperature detection device can detect the abnormality and issue an alarm in the first instance. It can detect potential problems of the mechanical seal device in the first instance and issue early warnings, enabling operators to promptly detect and eliminate faults, prevent the problem from escalating, and reduce operational risks and costs.

[0039] Furthermore, the feed pipe system includes a scraper 13, which is connected to the feed pipe 5. The scraper 13 is positioned above the disc filter assembly and close to the spray flushing pipe 12. This effectively and quickly flushes the filtrate residue on the filter disc 11, achieving the purpose of cleaning the filter disc without disassembling the equipment. This extends the service life of the filter disc without disassembling the equipment and reduces the workload of personnel.

[0040] Furthermore, the scraper 13 is arranged along the axial direction of the filter disc 11, and the blade of the scraper 13 is set close to the filter disc 11. When the filter disc 11 rotates, the scraper 13 rotates with the filter disc 11, which is beneficial for cleaning the filter disc 11.

[0041] Furthermore, a water distributor 14 is installed at the outlet of the feed pipe 5 to precisely direct the filtrate onto the filter plate 11, thereby accelerating the filtration process and saving time.

[0042] Furthermore, the feed pipe 5 and the cleaning pipe 4 are positioned close together, which effectively saves space inside the filter cartridge 15 and facilitates sealing inside the filter cartridge 15.

[0043] Example 2

[0044] In this embodiment, the motor and reducer are positioned at the top to save space at the bottom, depending on the customer's specific needs.

[0045] Example 3

[0046] Depending on the customer's needs, this embodiment does not include a cleaning component; the cleaning component is an optional accessory and can be configured according to requirements.
