Description

Technical Field

[0001] This utility model relates to the field of inclined tube sedimentation tank technology, and in particular to a high-efficiency inclined tube sedimentation tank for water treatment. Background Technology

[0002] In wastewater treatment, inclined tube sedimentation tanks are a commonly used type of wastewater treatment equipment. An inclined tube sedimentation tank refers to a sedimentation tank with inclined tubes in the sedimentation zone. There are two assembly forms: inclined tube and branch pipe. In the sedimentation zone of a horizontal or vertical flow sedimentation tank, a series of shallow sedimentation layers are divided by inclined parallel tubes or parallel pipes. The treated and settled sludge move and separate in each shallow sedimentation layer.

[0003] Patent publication number CN220360850U discloses an inclined tube sedimentation tank, including a sedimentation tank with multiple sedimentation units arranged inside. Each pair of adjacent sedimentation units is separated by a partition wall, which is fixedly connected to the sedimentation tank. An overflow trough is provided on the partition wall, with one end fixed to the right side of the top of the partition wall and a grid installed on the other end. Each sedimentation unit has a stainless steel mesh fixed inside, with an inclined tube on top of the stainless steel mesh. A sludge tank is provided at the bottom of the sedimentation tank, and an inlet is fixed at one end of the top of the sedimentation tank, while an outlet is fixed at the other end. By using multiple sedimentation units to perform multi-stage sedimentation of sewage, the sedimentation effect can be improved. Through multi-stage sedimentation and the grid, large particles of sediment and small particles of suspended solids can be effectively removed.

[0004] The above devices, in the process of sedimentation treatment of sewage, filter out suspended solids or colloidal impurities that may not settle quickly by setting up a bar screen. However, if the impurities connected to the bar screen are not cleaned for a long time, the pores of the bar screen will become clogged, and the interception and filtration tasks can no longer be performed. The solution provided by the above devices is to manually use tools to unclog and remove the impurities, which is labor-intensive and time-consuming, thus directly affecting the sewage treatment efficiency. Therefore, a high-efficiency inclined tube sedimentation tank for water treatment is proposed to solve the above problems. Utility Model Content

During this period, floating objects that cannot settle quickly are blocked by the filter screen when passing through it. When too much of the blocked impurities accumulate, the barrier frame is raised, and the impurities fall to the bottom of the barrier frame for collection. Finally, the first baffle is moved to one side until there is an opening at the bottom of the barrier frame, and the collected impurities fall downwards. This quickly achieves the purpose of cleaning and collecting floating objects, which is more labor-saving and convenient than manual fishing.

[0012] Preferably, the bottom wall of the receiving frame is integrally formed with a sloping bottom surface, and a door panel is provided on one side wall of the receiving frame. The door panel is connected to the receiving frame by a hinge. A second electric push rod is fixedly connected to the first bracket, and one end of the second electric push rod is fixedly connected to the receiving frame.

[0013] By adopting the above technical solution, the second electric push rod pushes and pulls the receiving frame after it is working.

[0014] Preferably, a limiting plate is fixedly connected to one side wall of the barrier frame, and the limiting plate penetrates one side wall of the first baffle.

[0015] By adopting the above technical solution, the limiting plate limits the first baffle.

[0016] Preferably, a baffle plate is fixedly connected to one side wall of the inner cavity of the shell. The baffle plate is located at the bottom of the water inlet pipe and has diversion grooves that are evenly distributed on the baffle plate.

[0018] Preferably, a drain frame is integrally formed at the bottom of the housing, a trapezoidal frame is integrally formed inside the drain frame, a second baffle is slidably connected inside the trapezoidal frame, and the second baffle extends into the drain frame and fits against the inner wall of the drain frame.

[0019] By adopting the above technical solution, the second baffle seals the bottom of the housing.

[0020] Preferably, a threaded adjusting rod is rotatably connected inside the sewage discharge frame, the threaded adjusting rod extends out of the sewage discharge frame, a rotating plate is fixedly connected to one end of the threaded adjusting rod, and the threaded adjusting rod passes through one side wall of the second baffle and is threadedly connected to the second baffle.

[0023] 1. A high-efficiency inclined tube sedimentation tank for water treatment, wherein, through the design of the impurity removal mechanism, sewage enters the shell through the inlet pipe, and the sediment accumulates at the bottom of the shell after passing through the honeycomb inclined tubes. During this period, floating objects that cannot settle quickly are blocked by the filter screen when passing through the filter screen. When too much impurity is accumulated, the filter frame is raised and the impurities fall to the bottom of the filter frame for collection. Finally, the first baffle is moved to one side until an opening is formed at the bottom of the filter frame, and the collected impurities fall downwards. This quickly achieves the purpose of cleaning and collecting floating objects, which is more labor-saving and convenient than manual collection.

[0024] 2. A high-efficiency inclined tube sedimentation tank for water treatment, in which sewage is discharged into the shell through the inlet pipe. After being discharged, the sewage first falls onto the baffle plate to be dispersed, and then flows through the diversion channel to promote the even downward flow of water after dispersion. This avoids the situation where water is concentrated and agitates the sediment, which would directly have an adverse effect on the sedimentation process, and effectively improves the stability of the sedimentation process.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The present invention will be described in further detail below.

[0034] This utility model discloses a high-efficiency inclined tube sedimentation tank for water treatment. (Refer to...) Figures 1-7 It includes a shell 1, a fixing frame 2 is fixedly connected inside the shell 1, a honeycomb inclined tube 3 is fixedly connected inside the fixing frame 2, a water inlet pipe 4 is fixedly connected to one side wall of the shell 1, a drain pipe 5 is fixedly connected to the other side wall of the shell 1, and a dirt removal mechanism 6 is provided on the shell 1.

[0035] The impurity removal mechanism 6 includes a horizontal plate 61, which is fixedly connected to the inside of the housing 1. A U-shaped plate 62 is fixedly connected to the top of the housing 1. A threaded control rod 63 is rotatably connected inside the U-shaped plate 62. A motor 64 is fixedly connected to the top of the U-shaped plate 62. The motor 64 is fixedly connected to one end of the threaded control rod 63 through its output shaft. A lifting plate 65 is slidably connected to the inside of the U-shaped plate 62. The threaded control rod 63 passes through the lifting plate 65 and is threadedly connected to the lifting plate 65. A barrier frame 66 is provided on one side of the horizontal plate 61. A connecting plate 67 is fixedly connected to one side of the lifting plate 65.

[0036] A connecting plate 67 is fixedly connected to one side of the barrier frame 66. A filter screen 68 is fixedly connected to one side wall of the barrier frame 66. A first baffle 69 is provided on one side of the filter screen 68. The first baffle 69 extends into the interior of the barrier frame 66 and fits against the inner wall of the barrier frame 66. A first electric push rod 691 is fixedly connected to one side wall of the barrier frame 66. One end of the first electric push rod 691 is fixedly connected to the inner side of the first baffle 69. A drain outlet 692 is provided on the bottom wall of the first baffle 69. Sewage enters the interior of the shell 1 through the inlet pipe 4, and its sediment flows through... After passing through the honeycomb inclined tube 3, the floating debris accumulates at the bottom of the shell 1. During this period, floating debris that cannot settle quickly is blocked by the filter screen 68 when passing through the filter screen 68. When too much debris is blocked, the barrier frame 66 is raised and the debris falls to the bottom of the barrier frame 66 for collection. Finally, the first baffle 69 is moved to one side until there is an opening at the bottom of the barrier frame 66, and the collected debris falls downwards. This quickly achieves the purpose of cleaning and collecting floating debris, which is more labor-saving and convenient than manual fishing.

[0037] A first bracket 693 is fixedly connected to the front side of the housing 1, and a second bracket 694 is fixedly connected to the rear side of the housing 1. A receiving frame 695 is provided on the top of the housing 1. An extension plate 696 is fixedly connected to one side of the receiving frame 695. A guide rod 697 is fixedly connected between the first bracket 693 and the second bracket 694. The guide rod 697 passes through the extension plate 696 and guides and limits the extension plate 696. An inclined bottom surface 698 is integrally formed on the bottom wall of the receiving frame 695. A door panel 699 is provided on one side wall of the receiving frame 695. The door panel 699 is connected to the receiving frame 695 by a hinge. A second electric push rod 681 is fixedly connected to the first bracket 693. One end of the second electric push rod 681 is fixedly connected to the receiving frame 695. After the second electric push rod 681 is working, it pushes and pulls the receiving frame 695.

[0038] A limiting plate is fixedly connected to one side wall of the barrier frame 66. The limiting plate penetrates one side wall of the first baffle 69 and limits the first baffle 69. A baffle plate 682 is fixedly connected to one side wall of the inner cavity of the shell 1. The baffle plate 682 is located at the bottom of the water inlet pipe 4. A diversion channel 683 is opened on the baffle plate 682. The diversion channels 683 are arranged at equal intervals on the baffle plate 682. After the sewage is discharged onto the baffle plate 682, it is dispersed and then diverted through each diversion channel 683.

[0039] The bottom of the housing 1 is integrally formed with a drain frame 684. Inside the drain frame 684, a trapezoidal frame 685 is integrally formed. A second baffle 686 is slidably connected inside the trapezoidal frame 685. The second baffle 686 extends into the drain frame 684 and fits against the inner wall of the drain frame 684. The second baffle 686 seals the bottom of the housing 1. A threaded adjusting rod 687 is rotatably connected inside the drain frame 684. The threaded adjusting rod 687 extends out of the drain frame 684. A rotating plate 688 is fixedly connected to one end of the threaded adjusting rod 687. The threaded adjusting rod 687 passes through one side wall of the second baffle 686 and is threadedly connected to the second baffle 686. After the threaded adjusting rod 687 rotates, it drives the second baffle 686 to move horizontally.

[0040] In actual operation, the device is first connected to the power supply. Wastewater is discharged into the shell 1 through the inlet pipe 4. After the wastewater is discharged, it first falls onto the baffle plate 682 and is dispersed. Then it is diverted through the diversion channel 683. This promotes the water to be dispersed and flows downward evenly, avoiding the situation where water is concentrated and disturbs the sediment, which directly has an adverse effect on the sedimentation work. After the wastewater enters the shell 1, the sediment settles to the bottom of the shell 1 after passing through the honeycomb inclined tube 3. During this period, the floating objects that cannot settle or cannot settle in time are blocked by the filter screen 68 after passing through the filter screen 68, thereby improving the wastewater treatment quality.

[0041] After the motor 64 starts working, it drives the threaded control rod 63 to rotate. The threaded control rod 63 drives the lifting plate 65 to rise and fall. The lifting plate 65 drives the connecting plate 67 to move. The connecting plate 67 drives the barrier frame 66 to rise and fall. By adjusting the height of the barrier frame 66 in this way, it can adapt to different water level filtration requirements. When there are a lot of impurities on the filter screen 68, repeat the above operation steps to control the barrier frame 66 to rise higher than the receiving frame 695. During the rising process, impurities enter the interior of the barrier frame 66 and accumulate, while water is discharged through the drain port 692.

[0042] After the barrier frame 66 is raised, the second electric push rod 681 pushes and pulls the receiving frame 695. When the receiving frame 695 moves directly below the barrier frame 66, the second electric push rod 681 pushes the first baffle 69, and then the impurities fall from the barrier frame 66 into the receiving frame 695. Finally, after the receiving frame 695 is moved to one side of the housing 1, the door panel 699 is opened, and the impurities inside the receiving frame 695 can be cleaned uniformly. The sloping bottom surface 698 of the receiving frame 695 is more conducive to the sliding of impurities, which facilitates the cleaning work. Based on the above operations, the floating objects are collected and cleaned, which saves more manpower than manual fishing. After the sediment enters the sewage discharge frame 684, the rotating plate 688 is rotated. The rotating plate 688 drives the threaded adjusting rod 687 to rotate. The threaded adjusting rod 687 drives the second baffle 686 to move, and the sediment is discharged downward.

[0043] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
