Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment equipment, and in particular relates to a sewage treatment device. Background Art

[0002] Sewage usually refers to the polluted water discharged from life and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse.

[0003] In sewage treatment, it is a common treatment process to pass the sewage through a reaction tank for chemical reaction and then pass it through a sedimentation tank for sedimentation and filtration. However, there are many problems with existing sewage treatment devices:

[0004] 1. Before the sewage enters the reaction tank for dosing, it is necessary to filter out the larger impurities in it. Usually, a filter is used for filtering. The filter is set at the top of the reaction tank and is not easy to clean;

[0005] 2. In order to speed up the reaction between the reagent and the sewage, a mixer is often used to stir the sewage and the reagent in the reaction tank, which increases the equipment processing and operation costs;

[0006] 3. After the sewage reacts with the reagent, it produces sediment, which needs to enter the sedimentation tank for sedimentation. However, when the sewage enters the sedimentation tank, the impact force on the inside of the sedimentation tank is relatively large, which will cause a large disturbance effect on the water body in the sedimentation tank, thereby affecting the sedimentation efficiency of the sewage in the sedimentation tank.

[0007] Therefore, a sewage treatment device is proposed. Utility Model Content

[0008] In order to solve the above technical problems, the utility model proposes a sewage treatment device.

[0009] In order to achieve the above-mentioned purpose, the utility model provides a sewage treatment device, comprising:

[0010] A reaction barrel, the top surface of which is open and a water inlet pipe is correspondingly provided;

[0011] A settling tank, wherein the settling tank is connected to the reaction tank through a water diversion pipe, a water pump is fixedly connected to the water diversion pipe, the bottom of the settling tank is conical and has a sewage pipe, an overflow trough is fixedly connected to the outside of the top of the settling tank, and the bottom of the overflow trough is connected to a drainage pipe;

[0012] One end of the water diversion pipe is connected to the bottom of the reaction barrel, and the other end penetrates into the bottom of the sedimentation barrel and is fixedly connected to a U-shaped pipe. The middle part of the U-shaped pipe is connected to the bottom of the water diversion pipe, and a plurality of water outlet holes are opened on both sides of the U-shaped pipe.

[0013] Preferably, the bottom of the precipitation barrel and the bottom of the reaction barrel are both circumferentially fixed with a plurality of support columns.

[0014] Preferably, a filter is fixedly connected to the top of the sedimentation barrel, and the water diversion pipe passes through the filter and is connected to the U-shaped tube.

[0015] Preferably, two slide rails are fixedly connected in parallel to the top of the reaction barrel, and filter screens are slidably connected to the two slide rails. Handles are fixedly connected to both sides of the top of the filter screen, and the filter screen is arranged corresponding to the water outlet of the water inlet pipe.

[0016] Preferably, the filter screen is fixedly connected with sliding wings on both sides corresponding to the sliding rail, and the sliding wings are slidably connected to the sliding rail.

[0017] Preferably, the inner bottom surface of the reaction barrel is inclined, and the lowest point of the bottom surface of the reaction barrel is connected to the water diversion pipe.

[0018] Preferably, a stirring shaft is rotatably connected to the center of the bottom surface of the reaction barrel, and a plurality of stirring blades are circumferentially fixedly connected to the outer side of the stirring shaft, and the stirring blades are arranged corresponding to the water outlet of the water inlet pipe.

[0019] Preferably, the stirring blade is an inclined blade.

[0020] Compared with the prior art, the utility model has the following advantages and technical effects:

[0021] Sewage enters the reaction barrel through the water inlet pipe, and an appropriate amount of reagent is added to the top of the reaction barrel. The reagent reacts with the sewage to produce flocs. The flocs are pumped into the water diversion pipe by the water pump, and then enter the U-shaped pipe through the water diversion pipe. The water flow directly impacts the horizontal pipe of the U-shaped pipe, slowing the water flow, and then it is divided from both sides of the U-shaped pipe and overflows upward, slowing down the water flow again, and finally flows out evenly from the water outlet holes on both sides of the U-shaped pipe. The impact force of the water flow slowed down by the U-shaped pipe is greatly reduced, and it flows out from the water outlet holes separately, which can avoid the rapid flow of water causing a large disturbance effect on the water body in the sedimentation barrel, thereby avoiding the impact of the sediment at the bottom of the sedimentation barrel, and improving the sedimentation efficiency of the sewage in the sedimentation barrel. After sedimentation in the sedimentation barrel, the flocculent sediment is discharged from the bottom sewage pipe, and the clean water overflows from the top of the sedimentation barrel into the overflow tank, and finally discharged through the drain pipe to complete the sewage treatment.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 4 As shown, this embodiment provides a sewage treatment device, comprising:

[0031] A reaction barrel 1, the top surface of which is open and a water inlet pipe 2 is correspondingly provided;

[0032] The sedimentation barrel 3 is connected with the reaction barrel 1 through a water diversion pipe 4, a water pump 5 is fixedly connected to the water diversion pipe 4, the bottom of the sedimentation barrel 3 is conical and has a sewage pipe 6, an overflow trough 7 is fixedly connected to the outside of the top of the sedimentation barrel 3, and a drainage pipe 8 is connected to the bottom of the overflow trough 7;

[0033] One end of the water pipe 4 is connected to the bottom of the reaction barrel 1, and the other end is fixedly connected to a U-shaped pipe 9 deep into the bottom of the sedimentation barrel 3. The middle part of the U-shaped pipe 9 is connected to the bottom of the water pipe 4, and a plurality of water outlet holes 10 are opened on both sides of the U-shaped pipe 9.

[0034] Sewage enters the reaction barrel 1 through the water inlet pipe 2, and a proper amount of reagent is added to the top of the reaction barrel 1. The reagent reacts with the sewage to produce flocs. The flocs are pumped into the water diversion pipe 4 by the water pump 5, and then enter the U-shaped pipe 9 through the water diversion pipe 4. The water flow directly impacts the horizontal pipe of the U-shaped pipe 9, slowing down the water flow, and then it is divided from both sides of the U-shaped pipe 9 and overflows upward, slowing down the water flow speed again, and finally flows out evenly from the water outlet holes 10 on both sides of the U-shaped pipe 9. The water flow slowed down by the U-shaped pipe 9 has a greatly reduced impact force, and flows out from the water outlet holes 10 respectively, which can avoid the rapid flow of water bringing a large disturbance effect to the water body in the sedimentation barrel 3, thereby avoiding the impact of the sediment at the bottom of the sedimentation barrel 3, and improving the sedimentation efficiency of the sewage in the sedimentation barrel 3. After sedimentation in the sedimentation barrel 3, the flocculent sediment is discharged from the bottom sewage pipe 6, and the clean water overflows from the top of the sedimentation barrel 3 into the overflow tank 7, and finally discharged through the drain pipe 8 to complete the sewage treatment.

[0035] Furthermore, a valve is provided in the sewage pipe 6 to control the on / off of sewage discharge.

[0036] According to a further optimized solution, a plurality of support columns 11 are circumferentially fixed to the bottom of the sedimentation barrel 3 and the bottom of the reaction barrel 1 .

[0037] The support column 11 supports the sedimentation barrel 3 to facilitate the discharge of sludge through the sewage pipe 6 at the bottom of the sedimentation barrel 3 .

[0038] According to a further optimized solution, a filter 12 is fixedly connected to the top of the sedimentation barrel 3 , and the water pipe 4 passes through the filter 12 and is connected to the U-shaped pipe 9 .

[0039] The filter 12 is preferably a honeycomb inclined tube filter 12, which has a good filtering effect. The clear water after precipitation is filtered again by the filter 12 during the gradual rise of the water level, which can filter out suspended matter or other fine impurities in the water, prevent flocs from overflowing with the water flow, and further increase the sewage treatment effect.

[0040] To further optimize the solution, two slide rails 13 are fixedly connected in parallel to the top of the reaction barrel 1 , a filter screen 14 is slidably connected to the two slide rails 13 , handles 15 are fixedly connected to both sides of the top of the filter screen 14 , and the filter screen 14 is arranged corresponding to the water outlet of the water inlet pipe 2 .

[0041] The filter screen 14 can perform preliminary filtration on the sewage before it enters the reaction barrel 1 to filter out larger impurities. After a period of time, the water inlet pipe 2 can be lifted, and then the handle 15 can be pulled to slide the filter screen 14 to the other side of the reaction barrel 1, and then the filter screen 14 can be lifted up to dump the impurities filtered on the filter screen 14, so that the filter screen 14 can be easily cleaned.

[0042] According to a further optimized solution, sliding wings 16 are fixedly connected to both sides of the filter screen 14 corresponding to the slide rail 13 , and the sliding wings 16 are slidably connected to the slide rail 13 .

[0043] Furthermore, the sliding wing 16 used in this embodiment is a right-angled sliding wing 16, which is clamped downward on the slide rail 13, which can limit the sliding of the filter screen 14 without affecting the removal of the filter screen 14, thereby facilitating the cleaning of the filter screen 14.

[0044] According to a further optimized solution, the bottom surface of the reaction barrel 1 is tilted, and the lowest part of the bottom surface of the reaction barrel 1 is connected to the water pipe 4 .

[0045] The bottom surface of the reaction barrel 1 is inclined, so that when the sewage flows into the sedimentation barrel 3, flocs are prevented from accumulating at the bottom of the reaction barrel 1 to form a dead corner.

[0046] According to a further optimized solution, a stirring shaft 17 is rotatably connected to the center of the bottom surface of the reaction barrel 1 , and a plurality of stirring blades 18 are fixedly connected to the outer circumference of the stirring shaft 17 . The stirring blades 18 are arranged corresponding to the water outlet of the water inlet pipe 2 .

[0047] The water flowing out of the water inlet passes through the filter screen 14 and falls on the stirring blade 18, which can push the stirring blade 18 to drive the stirring shaft 17 to rotate, thereby stirring the sewage and the reagent in the reaction barrel 1, so that the sewage and the reagent are mixed evenly and the reaction efficiency is accelerated.

[0048] In a further optimized solution, the stirring blade 18 is an inclined blade.

[0049] The stirring blade 18 is tilted to decompose the vertical force of falling water into a horizontal force that drives the stirring blade 18 to rotate. The stirring blade 18 is driven to rotate by the water flow, which saves electric energy and reduces the equipment processing and operation costs.
