Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to an industrial sewage purification device for environmental protection engineering. BACKGROUND

[0002] Environmental protection engineering refers to engineering made for environmental protection. Due to industrial development leading to environmental pollution, a certain group of people make engineering based on certain assumed goals, apply relevant scientific knowledge and technical means, and solve environmental pollution problems through organized activities. The content of environmental protection engineering mainly includes air pollution prevention and control engineering, water pollution prevention and control engineering, solid waste treatment and utilization engineering, and noise control engineering. Among them, water pollution prevention and control engineering is closely related to local natural conditions (terrain, weather, rivers, soil properties, etc.), social conditions (city, regional development, industrial and agricultural production, population density, traffic conditions, economic life, technical level, etc.).

[0003] Industrial sewage purification is an important part of water pollution prevention and control engineering. Industrial sewage includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated during industrial production, containing industrial production materials, intermediate products, by-products and pollutants generated during production. Because industrial wastewater often contains various toxic substances, it pollutes the environment and is harmful to human health. Therefore, before discharging industrial wastewater, it needs to be purified by a special treatment agent to make suspended solids and colloidal particles coagulate into large particles, and then removed by filtration.

[0004] Because the filter screen in the sewage purification equipment will be blocked by impurities after a long time of use, the treatment effect of industrial sewage is seriously reduced. Therefore, sewage purification equipment with self-cleaning function appears in the prior art. The principle is to clean the filter surface of the filter screen by the cleaning component, and then discharge the cleaned sewage from the equipment. However, since the filter screen relies on the gap on the filter screen to achieve the filtering effect, this will cause the impurities to accumulate in the gap of the filter screen and cause blockage after the sewage purification equipment is used for a period of time. The cleaning component is difficult to extend into the gap of the filter screen to clean the impurities inside the gap, resulting in poor cleaning effect of the filter screen and affecting the purification effect of industrial sewage.

[0043] a telescopic device 5, the telescopic device 5 is rotationally connected with the lower end of the hollow rotating shaft 7, and the telescopic device 5 is used for driving the hollow rotating shaft 7 to ascend or descend.

[0044] In specific use, the industrial wastewater and the treatment agent are introduced into the filter cartridge 3, the driving assembly drives the hollow rotating shaft 7 to rotate, the telescopic device 5 drives the hollow rotating shaft 7 to make lifting movement, the hollow rotating shaft 7 drives the stirring part and the liquid suction head 8 to make the combined movement of rotation and lifting, the industrial wastewater is stirred, the industrial wastewater and the treatment agent are fully mixed, the particulate impurities of the suspended solids and the colloidal particles are blocked in the filter cartridge 3, the liquid suction head 8 timely scrapes off the impurities on the inner wall of the filter cartridge 3, the permeability of the filter cartridge 3 is improved, and after the treatment is completed, the valve on the clean water outlet pipe 23 is opened, and the clean water is discharged from the clean water outlet pipe 23.

[0045] When the impurities are accumulated and blocked in the gap of the filter cartridge 3, the hollow rotating shaft 7 continues to rotate, the telescopic device 5 drives the hollow rotating shaft 7 to make intermittent lifting movement, and the sewage pump 6 is started, a negative pressure is formed in the hollow rotating shaft 7, the liquid suction head 8 absorbs the impurities accumulated in the gap of the filter cartridge 3 through the liquid inlet hole 9, and the clean water outside the filter cartridge 3 enters the liquid inlet hole 9 by penetrating the filter cartridge 3 under the action of the negative pressure, thereby backwashing the filter cartridge 3, improving the cleaning effect of the filter cartridge 3, and keeping the filter cartridge 3 in good filtering performance, thereby improving the purification effect of the industrial wastewater.

[0046] As shown in Figures 4-5 , in order to achieve the purpose of improving the cleaning effect of the filter cartridge 3, preferably, the liquid suction head 8 is a wedge-shaped structure.

[0047] Specifically, Figure 4 the arrow direction in the figure indicates the rotation direction of the stirring part, by setting the liquid suction head 8 as a wedge-shaped structure, after the impurities on the inner wall of the filter cartridge 3 are scraped off by the liquid suction head 8 in the backwashing process, the liquid inlet hole 9 can timely absorb and discharge the scraped-off impurities from the device, thereby avoiding that the scraped-off impurities are mixed in the wastewater again and cause burden to the wastewater purification.

[0048] As shown in Figure 2 and Figures 4-5 , in order to achieve the purpose of improving the cleaning effect of the filter cartridge 3, preferably, a wedge-shaped block 10 is arranged on the inner wall of the filter cartridge 3.

[0049] The stirring part comprises:

[0050] A rod sleeve 11 is arranged on the hollow rotating shaft 7, the inside of the rod sleeve 11 is in communication with the inside of the hollow rotating shaft 7, and a limiting ring is arranged in the inside of the rod sleeve 11.

[0051] A hollow inner rod 12 is slidably connected to one end of the rod sleeve 11 away from the hollow rotating shaft 7, a spring 24 is arranged between the hollow inner rod 12 and the limiting ring, the inside of the hollow inner rod 12 is in communication with the inside of the rod sleeve 11, the liquid suction head 8 is fixedly connected to the hollow inner rod 12, and the liquid inlet hole 9 is in communication with the inside of the hollow inner rod 12.

[0052] Specifically, in the process of purifying industrial wastewater, the hollow rotating shaft 7 drives the stirring part and the liquid suction head 8 to rotate. When the liquid suction head 8 contacts the wedge-shaped block 10, the spring 24 is compressed and stored. When the liquid suction head 8 is separated from the wedge-shaped block 10, the spring 24 drives the liquid suction head 8 to pop out under the action of elastic potential energy. The liquid suction head 8 knocks the filter cartridge 3, causing the filter cartridge 3 to vibrate and shake off the impurities attached to the inner wall, improving the cleaning effect of the filter cartridge 3, maintaining good filtering performance of the filter cartridge 3, and improving the purification effect of industrial wastewater.

[0053] As shown in Figures 1-2 , in order to achieve the purpose of improving the purification effect of industrial wastewater, preferably, the filter cartridge 3 is rotatably connected inside the purification tank 2, the hollow rotating shaft 7 is provided with a driving gear 13, the inner wall of the filter cartridge 3 is provided with an inner gear ring 14, and the inside of the purification tank 2 is rotatably connected with a driven gear 15. The driven gear 15 is simultaneously engaged with the driving gear 13 and the inner gear ring 14.

[0054] Specifically, in the process of purifying industrial wastewater, the hollow rotating shaft 7 drives the driven gear 15 to rotate through the driving gear 13 (during the lifting process of the hollow rotating shaft 7 driving the driving gear 13, the driving gear 13 will not be disengaged from the driven gear 15). The driven gear 15 drives the filter cartridge 3 to rotate through the inner gear ring 14. The rotating direction of the filter cartridge 3 is opposite to that of the stirring part, so that more turbulence and vortexes are generated, further enhancing the stirring effect. This complex water flow state helps to break the stratification and local flow dead zones that may form in the wastewater, making the mixing of wastewater and treatment agent more sufficient and uniform, increasing the contact area and reaction opportunity between the two, thereby improving the use efficiency of the treatment agent and the purification effect of the wastewater.

[0060] the driven bevel gear 21 is engaged with the driving bevel gear 20, and the inner side wall of the driven bevel gear 21 is provided with a spline groove 22 matched with the spline 18.

[0061] Specifically, the drive unit 19 drives the active bevel gear 20 to rotate, and the active bevel gear 20 drives the hollow shaft 7 to rotate through the driven bevel gear 21.

[0062] like Figure 1 As shown, in order to achieve continuous or intermittent lifting of the hollow rotating shaft 7, preferably, the telescopic device 5 is an electric push rod, a hydraulic rod, or a cylinder.

[0063] Specifically, the telescopic device 5 drives the hollow rotating shaft 7 to rise and fall, and the liquid outlet 17 is always inside the collection box 16 to facilitate the discharge of sewage.

[0064] The working process of this invention is as follows: Industrial wastewater and treatment agent are introduced into the filter cartridge 3. The drive unit 19 drives the active bevel gear 20 to rotate. The active bevel gear 20 drives the hollow rotating shaft 7 to rotate through the driven bevel gear 21. The telescopic device 5 drives the hollow rotating shaft 7 to move up and down, so that the hollow rotating shaft 7 drives the stirring component and the liquid suction head 8 to perform a combined rotation and lifting motion, thus stirring the industrial wastewater. The hollow rotating shaft 7 drives the driven gear 15 to rotate through the active gear 13. The driven gear 15 drives the filter cartridge 3 to rotate through the internal gear ring 14. The rotation direction of the filter cartridge 3 is opposite to the rotation direction of the stirring component, which generates more turbulence and vortex. The vortex further enhances the stirring effect, trapping suspended solids and colloidal particles inside the filter cartridge 3. The suction head 8 promptly scrapes off impurities from the inner wall of the filter cartridge 3, improving its permeability. When impurities accumulate and clog the gaps in the filter cartridge 3, the hollow shaft 7 continues to rotate, and the telescopic device 5 drives the hollow shaft 7 to perform intermittent lifting and lowering movements. Simultaneously, the sewage pump 6 is activated, creating negative pressure inside the hollow shaft 7. The suction head 8 adsorbs the impurities accumulated in the gaps of the filter cartridge 3 through the inlet hole 9. Under the action of negative pressure, the clean water outside the filter cartridge 3 passes through the filter cartridge 3 and enters the inlet hole 9, backwashing the filter cartridge 3.

[0065] Compared with the prior art, the industrial wastewater and the treating agent are introduced into the filter cylinder 3, the driving assembly drives the hollow rotating shaft 7 to rotate, the telescopic device 5 drives the hollow rotating shaft 7 to make lifting movement, the hollow rotating shaft 7 drives the stirring part and the liquid suction head 8 to make the combined movement of rotation and lifting, the industrial wastewater is stirred, the industrial wastewater and the treating agent are fully mixed, the particulate impurities of the suspended matter and the colloidal particles are blocked in the filter cylinder 3, the impurities on the inner wall of the filter cylinder 3 are scraped off in time by the liquid suction head 8, the permeability of the filter cylinder 3 is improved, when the impurities are accumulated and blocked in the gap of the filter cylinder 3, the hollow rotating shaft 7 continues to rotate, the telescopic device 5 drives the hollow rotating shaft 7 to make intermittent lifting movement, meanwhile, the sewage pump 6 is started, the negative pressure is formed in the hollow rotating shaft 7, the impurities accumulated in the gap of the filter cylinder 3 are adsorbed by the liquid suction head 8 through the liquid inlet hole 9, the clean water outside the filter cylinder 3 passes through the filter cylinder 3 and enters the liquid inlet hole 9 under the action of the negative pressure, the filter cylinder 3 is back-flushed, the cleaning effect of the filter cylinder 3 is improved, the filter cylinder 3 keeps good filtering performance, and the purification effect of the industrial wastewater is improved.
