Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment control, and in particular to a pre-mixing treatment device for precise filtration of sewage. Background Art

[0002] Filtration and treatment of industrial or domestic sewage is an important task for municipal engineering or enterprises and institutions. The main purposes of sewage filtration include: Removal of suspended matter: interception of larger suspended particles, fibers, pulp, algae, etc. in sewage to make the water clear. Protection of subsequent treatment equipment: prevent suspended particles from causing wear or blockage of subsequent treatment equipment (such as water pumps, pipes, sedimentation tanks, etc.), and extend the service life of the equipment. Improve treatment effect: provide better conditions for subsequent sewage treatment processes (such as biological treatment, chemical treatment, etc.), which helps to improve the efficiency and effect of the entire sewage treatment system.

[0003] However, existing sewage treatment technologies have the following shortcomings: (1) Filter media clogging: As filtration proceeds, the surface of the filter media may gradually become clogged with pollutants, resulting in increased filtration resistance and decreased filtration efficiency. This requires regular cleaning or replacement of the filter media, which increases maintenance costs and workload. (2) Limited removal of tiny particles and soluble substances: Although filtration can effectively remove larger suspended particles, the removal effect on very small particles and soluble substances may not be ideal. Therefore, if sewage is only transported to a purification tank or filter tank through a pipeline for passive or static filtration treatment, its filtration performance is poor and the sewage treatment performance and efficiency are greatly reduced.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiment of the present application.

[0025] refer to Figure 1-4 As shown, the present application provides a pre-mixing treatment device for precise filtration of sewage, including: a frame 11, a delivery pump 12, a first pipeline 21, a second pipeline 22, a third pipeline 23, a filter chamber 13, a roller 14, a guide rod 15, a cylinder 16, a delivery chamber 17, an infrared distance sensor 31, a solenoid valve 32 and a controller 33.

[0026] The delivery pump 12 is fixedly arranged on the frame 11, the input end of the delivery pump 12 is connected to the first pipeline 21, the output end of the delivery pump 12 is connected to the second pipeline 22, the third pipeline 23 is fixedly arranged on the frame 11 in the horizontal direction, the end of the second pipeline 22 is connected to one end of the third pipeline 23, the other end of the third pipeline 23 is accommodated in the filter chamber 13, and a purification filter element is arranged in the filter chamber 13. The sewage is transported to the inside of the filter chamber 13 through the second pipeline 22 and the third pipeline 23 under the drive of the delivery pump 12, and the sewage is purified or filtered by the purification filter element arranged in the filter chamber 13.

[0027] The third pipeline 23 is arranged inside the filter cavity 13, one end of the third pipeline 23 is accommodated in the filter cavity 13 and the other end of the third pipeline 23 is located outside the filter cavity 13. The third pipeline 23 is located between the guide rods 15 on both sides of the filter cavity 13. The third pipeline 23 is arranged inside the filter cavity 13, and the stability and guidance of the filter cavity 13 during the movement along the guide rods 15 can also be improved.

[0028] The second pipeline 22 is connected to the purification pipeline 24, and the solenoid valve 32 is arranged on the purification pipeline 24. The solenoid valve 32 is used to control the opening or closing of the purification pipeline 24. Specifically, the purification pipeline 24 is used to transport polyacrylamide liquid, wherein the polyacrylamide liquid is usually used as a coagulant, and is combined with other coagulants to enhance the flocculation effect and accelerate the sedimentation speed. For example, when treating urban domestic sewage, the efficiency of solid-liquid separation can be improved. The solenoid valve 32 arranged on the purification pipeline can adjust the on-off control of the transportation of the polyacrylamide liquid and the control of the transportation flow rate.

[0029] A discharge pipe is arranged on the side wall of the filter chamber 13 , and the conveying chamber 17 is fixedly arranged on the frame 11 and is located below the discharge pipe. After being filtered in the filter chamber 13 , the sewage is discharged from the discharge pipe and flows into the conveying chamber 17 , and is discharged outward from the conveying chamber 17 after being filtered in the filter chamber 13 .

[0030] The guide rod 15 is horizontally arranged on the frame 11 and is respectively located on both sides of the filter chamber 13. The filter chamber 13 is provided with a roller 14, which is slidably connected to the guide rod 15. The cylinder 16 is fixedly arranged on the frame 11. The output end of the cylinder 16 is connected to the side wall of the filter chamber 13. The output end of the cylinder 16 is telescopically moved to drive the filter chamber 13 to move along the length direction of the guide rod 15. When the filter chamber 13 moves along the guide rod 15, the end of the third pipeline 23 close to the filter chamber 13 is always located inside the filter chamber 13.

[0031] like Figure 2 As shown, the filter chamber 13 moves a certain distance under the drive of the cylinder 16, and the filter chamber 13 is driven by the cylinder 16 to move along the guide rod 15, so that the end of the third pipeline 23 for conveying sewage and the side wall of the filter chamber 13 can move relative to each other, thereby causing the sewage outputted from the end of the third pipeline 23 to produce different flow changes when impacting the side wall of the filter chamber 13, thereby improving the flow performance of the sewage in the filter chamber 13, so as to improve the contact performance and filtering performance between the sewage and the filter element in the filter chamber 13.

[0032] During the movement of the filter chamber 13 driven by the cylinder 16, the distance between the end of the third pipe 23 located inside the filter chamber 13 and the side wall of the filter chamber 13 close to the third pipe 23 changes relatively dynamically, so that when the sewage is discharged from the end of the third pipe 23, it will impact the side wall of the filter chamber 13 at different distances from the end of the third pipe 23, thereby generating reverse reflux sewage with different flow states.

[0033] The infrared distance sensor 31 is arranged on the side wall of the filter chamber 13, and is used to obtain a distance detection value. The distance detection value is the horizontal distance between the side wall of the filter chamber 13 facing the second pipeline 22 and the side of the frame 11. The distance detection value is used to determine the distance between the end of the third pipeline 23 and the side wall of the filter chamber 13 close to the end of the third pipeline 23, wherein the end of the third pipeline 23 refers to the end of the side where the third pipeline 23 outputs the sewage liquid flow.

[0034] The controller 33 is configured to adjust the opening or closing state of the solenoid valve 32 or the opening size of the solenoid valve 32 according to the size relationship between the distance detection value and the preset distance value.

[0035] Specifically, the controller 33 is configured to: if the distance detection value is greater than or equal to the preset distance value, the solenoid valve 32 is controlled to be in a closed state. Wherein, if the distance detection value is greater than or equal to the preset distance value, it means that the distance between the end of the third pipeline 23 and the side wall of the filter chamber 13 close to the end of the third pipeline 23 is large, therefore, when the end of the third pipeline 23 outputs the sewage liquid flow, less liquid flow will impact the side wall of the filter chamber 13, thereby generating a smaller reverse impact liquid flow, which has little effect on the flow performance of the liquid flow in the filter chamber 13. Under this working condition, the solenoid valve 32 is driven to be in a closed state, thereby preventing the liquid flow of the purification pipeline from being transported, and filtering is only performed through the filter element in the filter chamber 13.

[0036] Further, the controller 33 is configured to: if the distance detection value is less than the preset distance value and greater than the minimum distance threshold, the solenoid valve 32 is controlled to be in an open state and the solenoid valve 32 is kept in an open state with a maximum opening. Wherein, if the minimum distance threshold is less than the preset distance value, and the distance detection value is less than the preset distance value and greater than the minimum distance threshold, it means that the distance between the end of the third pipeline 23 and the side wall of the filter chamber 13 close to the end of the third pipeline 23 is small, therefore, when the end of the third pipeline 23 outputs the sewage liquid flow, part of the liquid flow will impact the side wall of the filter chamber 13, thereby generating a large reverse impact liquid flow, which has a great influence on the flow performance of the liquid flow in the filter chamber 13. Under this working condition, the solenoid valve 32 is driven to be in an open state, thereby starting the liquid flow delivery of the purification pipeline, and the opening of the solenoid valve 32 is the maximum, so that the maximum amount of purified liquid can be delivered from the purification pipeline, thereby improving the mixing performance of the liquid flow in the filter chamber 13, and making the purified liquid and sewage in the filter chamber 13 achieve efficient mixing with the power brought by the reverse impact liquid flow.

[0037] Further, the controller 33 is configured to: if the distance detection value is less than the minimum distance threshold, the solenoid valve 32 is controlled to be in an open state and the solenoid valve 32 is opened at 50% of the maximum opening value to maintain the open state. Wherein, if the distance detection value is less than the minimum distance threshold, it means that the distance between the end of the third pipeline 23 and the side wall of the filter chamber 13 close to the end of the third pipeline 23 is at the minimum distance. Therefore, when the end of the third pipeline 23 outputs the sewage liquid flow, part of the liquid flow will impact the side wall of the filter chamber 13, but the end of the third pipeline 23 is close to the side wall of the filter chamber 13, and the reverse impact liquid flow generated is extremely large. At this time, the opening of the solenoid valve 32 is reduced to reduce the flow rate of the purified liquid flow transported on the purification pipeline, and avoid the large flow of purified liquid brought by the solenoid valve 32 when it is opened with a larger opening, thereby causing a large impact on both sides of the filter chamber 13, thereby ensuring the working stability of the whole machine, preventing the impact of the reverse liquid flow and the purified liquid delivery impact on both sides of the filter chamber 13, ensuring the stability of sewage treatment and reducing the vibration of the whole machine.

[0038] During the movement of the filter chamber 13, in order to make full use of the different reverse impact liquid flows generated by the output sewage at the end of the third pipeline 23 and the side wall of the filter chamber 13, the controller 33 adjusts the working state of the solenoid valve 32 through the distance detection value obtained by the infrared distance sensor 31 to achieve control of the purified liquid transported on the second pipeline 22, thereby improving the mixing effect of the purified liquid and sewage in the filter chamber 13, thereby achieving efficient adjustment treatment when filtering sewage and improving sewage treatment performance.
