DETAILED DESCRIPTION
[0023] 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.
[0024] like Figure 1 As shown, a sewage purification treatment device for a municipal sewage pipe network includes: an inlet pipe 1, the inlet pipe 1 is connected to the source of sewage, at the source of sewage, there is a water source containing solid garbage entering a first treatment box 2 through the inlet pipe 1, a solid sedimentation tank 3 is provided at the rear end of the first treatment box 2, a water retaining assembly 4 is detachably connected to the front end of the solid sedimentation tank 3, a diversion tank 5 is provided at the front end of the water retaining assembly 4, a plurality of diversion pipes 6 are provided at the bottom of the diversion tank 5, the diversion pipes 6 are connected to a second treatment box 7, an oil removal component is detachably connected to the second treatment box 7, an outlet pipe 8 is provided at the bottom of the second treatment box 7, the other end of the outlet pipe 8 is connected to a collection pipe 9, and the sewage that has been preliminarily treated continues to be diverted to the next treatment link or discharged to the outside.
[0025] like Figure 2 , 3 The solid sedimentation tank 3 is recessed at the bottom of the first treatment box 2, and the water inlet pipe 1 is bent toward the solid sedimentation tank 3. The solid sedimentation tank 3 is a quadrangular cone, and the top area of the solid sedimentation tank 3 is larger than the bottom area. When the sewage leaves the water inlet pipe 1, it directly impacts into the solid sedimentation tank 3. The solid garbage in the sewage with a density greater than that of water is precipitated at the bottom of the solid sedimentation tank 3. Because the bottom surface of the solid sedimentation tank 3 is lower than the bottom surface of the first treatment box 2, the garbage settled at the bottom of the solid sedimentation tank 3 will no longer be impacted upwards, and the solid garbage in the sewage will settle and accumulate in the solid sediment.
[0026] An opening 31 is provided on the side wall of the solid sedimentation tank 3, and a sealing plate 32 is detachably connected to the opening 31. A sealing strip is installed on the side of the sealing plate 32, and the sealing strip can seal the periphery of the opening 31 and the sealing plate 32 to prevent sewage from leaking from between the sealing plate 32 and the opening 31. Screws are also screwed between the sealing plate 32 and the side wall of the solid sedimentation tank 3 to further fix the position. When the amount of garbage in the solid sedimentation tank 3 is too much, the solid sedimentation tank 3 needs to be cleaned. At this time, the screws on the sealing plate 32 are unscrewed, the sealing plate 32 is pulled outward, and the garbage in the solid sedimentation tank 3 is unloaded. When clearing the garbage in the solid sedimentation tank 3, the inflow of sewage from the water inlet pipe 1 should be suspended.
[0027] like Figure 2As shown, the water retaining assembly 4 includes a grille plate 41 and a closing plate 42. The closing plate 42 is arranged behind the grille plate 41. The grille plate 41 is used to block floating garbage. The closing plate 42 can be installed when the second treatment box 7 is overhauled. The closing plate 42 divides the first treatment box 2 into two sections. A part of the sewage can be stored and precipitated on one side of the solid sedimentation tank 3. No water flows into the second treatment box 7 to affect the maintenance.
[0028] Two sets of slideways 21 are provided on the side wall of the first treatment box 2, and the grid plate 41 and the closing plate 42 are respectively slidably connected to the slideways 21. When installing the grid plate 41 or the closing plate 42, they can be directly inserted into the slideways 21. Through a simple insertion method, it is convenient to replace the grid plate 41 and remove the closing plate 42. The bottom of the grid plate 41 fits with the solid sedimentation tank 3. When the floating garbage is blocked by the grid plate 41, the garbage directly slides into the solid sedimentation tank 3 when the water level drops.
[0029] The sewage passes through the grid plate 41 and enters the diverter pool 5, which is recessed at the bottom of the first treatment box 2. Two connecting holes are provided at the bottom of the diverter pool 5, and the diverter pipe 6 is inserted into the connecting holes. The water entering the diverter pool 5 flows into the diverter pipe 6, and the sewage in the diverter pipe 6 enters the corresponding second treatment box 7.
[0030] The first solenoid valve 61 is provided in the shunt pipe 6, and the first solenoid valve 61 controls whether the water in the shunt pipe 6 can flow to the second treatment box 7. During the actual purification operation, the first solenoid valves 61 in the two shunt pipes 6 are opened individually, and only one shunt pipe 6 is kept unobstructed. The shunt pipe 6 is connected to the upper part of the side wall of the second treatment box 7, and the sewage flowing out of the shunt pipe 6 enters the upper part of the second treatment box 7.
[0031] like Figure 4 As shown, a support frame 71 is fixedly connected to the inner wall of the second treatment box 7, and oil-absorbing cotton 72 is mounted on the support frame 71. The oil-absorbing cotton 72 allows water to pass through but absorbs oil in the sewage. The side wall of the oil-absorbing cotton 72 is provided with a stainless steel frame 73. The stainless steel frame 73 allows the oil-absorbing cotton 72 to be stably mounted on the support frame 71. When the sewage submerges the oil-absorbing cotton 72, the oil-absorbing cotton 72 will not be forced to float. When the oil-absorbing cotton 72 needs to be replaced, the oil-absorbing cotton 72 and the stainless steel frame 73 can be directly picked up and replaced.
[0032] The oil-absorbing cotton 72 is arranged below the entrance of the diversion pipe 6. When the sewage flows into the second treatment box 7, it first flows into the bottom of the second treatment box 7 through the oil-absorbing cotton 72. When the sewage submerges the oil-absorbing cotton 72, the sewage is stopped from flowing in and is left to stand still for a period of time, so that the oil mixed in the water and not initially absorbed by the oil-absorbing cotton 72 floats up and is then absorbed by the oil-absorbing cotton 72, thereby effectively reducing the oil content in the sewage.
[0033] The water outlet pipe 8 is located at the bottom of the second treatment box 7 . A second solenoid valve 81 is provided on the water outlet pipe 8 . The second solenoid valve 81 controls whether the sewage in the second treatment box 7 can flow into the collecting pipe 9 through the water outlet pipe 8 .
[0034] Since it takes time for sewage to stand and absorb oil, in order to ensure the efficiency of sewage treatment, two diversion pipes 6, a second treatment box 7 and a water outlet pipe 8 are set. When the second treatment box 7 on one side is taking in water and absorbing oil, the second solenoid valve 81 under the second treatment box 7 on the other side is opened to allow the adsorbed sewage to flow out. After the sewage flows out, the second solenoid valve 81 is closed and the first solenoid valve 61 is opened to store water and stand. At this time, the side that has just started to stand and absorb oil begins to drain water, and the two second treatment boxes 7 perform oil absorption and standing operations alternately, which ensures the oil treatment without affecting the treatment efficiency.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
