Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a sedimentation-type treatment device for sewage containing multiple impurities. Background Art

[0002] One process in wastewater treatment involves adding chemicals to precipitate impurities. After adding chemicals, the solution is typically left to stand for a period of time, allowing the impurities to slowly settle to the bottom of the wastewater tank. The decontaminated wastewater and the precipitated impurities are then discharged into separate containers for further processing.

[0003] There are two problems with this process. First, if too little chemical is added, too little impurity may be precipitated, resulting in substandard wastewater treatment. However, adding too much chemical is wasteful. Second, the settling time is difficult to control: too short a settling time results in incomplete precipitation, while too long a settling time affects work efficiency.

[0004] In addition, when removing impurities from sewage and impurity sediment, how to avoid carrying away the sediment when discharging sewage? When discharging sediment, the sediment easily adheres to the bottom of the pool, resulting in unclean discharge. Summary of the Invention

[0005] The purpose of the present invention is to provide a sedimentation treatment equipment for sewage with multiple impurities. By arranging floating tubes at the four corners of the bottom of the sewage pool, the buoyancy change caused by the density change during the sewage decontamination process is utilized. The buoyancy of the sewage that meets the standard is detected through advance tests to set the gravity of the floating tube and the volume of the floating block, so that the floating tube automatically falls after the sewage decontamination meets the standard, starting sewage discharge and sedimentation extraction.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figures 1 to 9 As shown, the present invention includes a sewage pool 10, wherein a bottom plate 101 is slidably connected to the bottom of the sewage pool 10, and a support member 102, a sewage discharge member 103 and a floating pipe member 104 are provided at the bottom of the bottom plate 101;

[0030] The interior of the support member 102 is connected to the air pump 109 via an air pipe 108, the upper end of the sewage discharge member 103 is connected to the sewage outlet 11 on the base plate 101, and the lower end is connected to the sewage pump 111 via a sewage pipe 110. A drainage socket 112 is provided at the bottom of the floating tube member 104, and the bottom of the drainage socket 112 is connected to a drainage pipe 107.

[0031] The support member 102 includes a support cylinder 121 and a telescopic support column 122. The bottom of the telescopic support column 122 is movably connected to the support cylinder 121, and the top of the telescopic support column 122 is fixedly connected to a support plate 123, which is fixedly connected to the bottom of the base plate 101. A tracheal valve 105 is provided at the bottom of the support cylinder 121, and the support cylinder 121 is connected to the air supply pipe 108 through the tracheal valve 105.

[0032] The sewage discharge member 103 includes a connector 131, a telescopic tube 132, and a fixed tube 133. The connector 131 is fixedly connected to the bottom of the base plate 101 and communicates with the sewage outlet 11. The top of the telescopic tube 132 is fixedly connected to the connector 131, and the bottom of the telescopic tube 132 is slidably connected to the fixed tube 133. The sewage pipe 110 is also connected to the fixed tube 133. A sewage valve 106 is also provided on the sewage pipe 110.

[0033] Specifically, the floating tube assembly 104 includes a floating block 141, an active connecting tube 142, and an active drain pipe 144. The floating block 141 is located above the base plate 101 and is fixedly connected to the active connecting tube 142. The lower end of the active connecting tube 142 passes through the base plate 101 and is slidably connected thereto. The active drain pipe 144 is slidably connected within the active connecting tube 142. The drain socket 112 is located directly below the active connecting tube 142. The active drain pipe 144 has the same diameter as the drain socket 112, and a filter port 145 is provided on the upper side of the active drain pipe 144.

[0034] By utilizing the change in buoyancy caused by the precipitation of impurities, after the sewage treatment meets the standards, the buoyancy of the floating block 141 is less than the gravity of the floating tube 104, so the floating tube 104 moves downward as a whole, so that the movable connecting pipe 142 is inserted into the drainage socket 112, and the drainage socket 112 pushes out the movable drainage pipe 144, so that the filter port 145 on the upper side of the movable drainage pipe 144 is exposed, and the supernatant 13 begins to be discharged.

[0035] In addition, a limit block 143 is fixedly connected to the side wall of the movable connecting pipe 142, and the limit block 143 is located below the bottom plate 101. The buoyancy of the floating block 141 in the sewage 12 is greater than the weight of the floating tube 104, and the buoyancy of the floating block 141 in the supernatant 13 is less than the weight of the floating tube 104.

[0036] Specific implementation and principle:

[0037] After the sewage 12 is pre-treated, it is injected into the sewage pool 10 for chemical addition and precipitation. When the sewage 12 is injected into the sewage pool 10, the bottom plate 101 descends under the gravity of the sewage 12, and then the floating tube 104 descends. When the sewage 12 submerges the floating tube 104, the buoyancy of the float 141 is greater than the gravity of the float 104. Therefore, the float 141 will rise with the floating tube 104 as the sewage 12 is injected until the limit block 143 abuts against the bottom plate 101. Figure 4 shown.

[0038] Then, as the sewage 12 continues to be injected, the bottom plate 101 gradually drops until the tracheal valve 105 reaches the upper pressure limit (the tracheal valve 105 is a pressure valve that automatically opens when the pressure reaches a certain level). The tracheal valve 105 opens, causing the bottom plate 101 to drop directly to the bottom.

[0039] After the sewage 12 fills the sewage tank 10, an appropriate amount of medication is first added, followed by small amounts of medication at regular intervals. Impurities in the sewage 12 gradually precipitate, separating into a supernatant 13 at the top and a precipitate 14 at the bottom. Once the supernatant 13 reaches the required level, the buoyancy of the float block 141 is less than the weight of the float tube 104. Therefore, the float tube 104 moves downward as a whole, allowing the movable connecting pipe 142 to be inserted into the drain socket 112. The drain socket 112 pushes the movable drain pipe 144 out, exposing the filter port 145 on the upper side of the movable drain pipe 144 and allowing the supernatant 13 to be discharged. At the same time, the addition of medication is stopped. When discharging the supernatant, only the clear water above the float tube 104 is drained, minimizing the amount of sediment carried over the supernatant.

[0040] After the supernatant 13 above the floating tube 104 is drained, the drain valve 106 is opened, and the drain pump 111 begins to suck the sediment 14 and the remaining supernatant 13 from the drain port 11 through the drain pipe 110. Simultaneously, the air pump 109 intermittently inflates the support cylinder 121, and after inflation, the air pipe valve 105 is opened to deflate. This periodic inflation and deflation causes the telescopic support column 122 to move up and down rapidly, thereby vibrating the bottom plate 101 up and down, preventing sediment from adhering to the bottom plate 101 and allowing the sediment to be drained as cleanly as possible.

[0041] After the sediment is discharged, the air pump 109 is used to inflate the supporting air cylinder 121 so that the bottom plate 101 returns to its original position and waits for the next sewage treatment.

[0042] Based on the above, the present invention utilizes the change in buoyancy caused by impurity precipitation to stop dosing and automatically discharge wastewater once wastewater treatment meets standards, ensuring both effective and efficient wastewater treatment. During supernatant discharge, only the clear water above the float is removed, while the remaining clear water below the float is removed along with the sediment, minimizing sediment carryover during supernatant discharge. After the supernatant is completely discharged, the support member is rapidly moved up and down by inflation and deflation, which in turn causes the bottom plate to vibrate up and down, preventing sediment from adhering to the bottom plate and maximizing its removal.

[0043] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
