Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a water distribution tank for a denitrification deep bed filter. Background Technology

[0002] Deep bed denitrification filters are treatment units that combine biological denitrification and filtration functions. They are a unique and advanced treatment process that combines denitrification and filtration, and are a common biological treatment technology that can effectively remove nitrogen pollutants and fixed impurities from water.

[0003] During operation, sludge and impurities may accumulate inside the distribution tank. Cleaning these debris can be difficult due to the inability to quickly open certain components or covers, making it hard to thoroughly clean hard-to-reach and hidden areas. Long-term accumulation can affect the uniformity of water distribution, thus impacting the filter's treatment efficiency and potentially leading to significant wastewater leakage. This can disrupt the entire wastewater treatment system, escalate the malfunction, and increase maintenance costs and accident losses. During operation, some sludge enters the distribution tank with the water flow. Over time, this sludge gradually accumulates at the bottom of the tank. Sludge accumulation not only occupies valuable space in the distribution tank but also affects the uniformity of water distribution, resulting in uneven distribution of wastewater entering the denitrification deep bed filter. This negatively impacts the filter's treatment efficiency, necessitating more frequent backwashing, increasing operating costs and wasting water resources. Utility Model Content

[0004] The main purpose of this utility model is to provide a water distribution tank for a denitrification deep bed filter, which can effectively solve the problem of large-scale sewage leakage, affecting the normal operation of the entire sewage treatment system, further amplifying the fault, and increasing maintenance costs and accident losses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water distribution tank for a denitrification deep bed filter, comprising a tank body, with support plates fixedly connected to both the left and right sides of the tank body, water distribution troughs provided on the upper side walls of both support plates, fixing plates fixedly connected to both the left and right sides of the bottom wall of each water distribution trough, two locking blocks fixedly connected to the bottom wall of each fixing plate, two outer shells fixedly connected to the inside of each support plate, support rods slidably connected to the front and rear sides of the inside of each outer shell, and a first spring fixedly connected to the rear side wall of every two support rods.

[0006] Furthermore, the other end of every four first springs is fixedly connected to the inside of a housing, and each housing has a placement slot inside, with two second springs fixedly connected to the bottom wall of each placement slot.

[0007] Furthermore, a first baffle is fixedly connected to the top of each pair of second springs, each first baffle is disposed inside a placement groove, the top of each first baffle is corresponding to the bottom wall of the locking block, and the hole groove of each locking block is corresponding to the top of the support rod.

[0008] Furthermore, both sides of the two water distribution tanks are connected to water inlet pipes, and the outer sides of the four water inlet pipes are all connected through the inner side walls of the left and right sides of the pool body.

[0009] Furthermore, each of the water distribution tanks has a support rod fixedly connected to its inner top, and each of the water distribution tanks has a water outlet on its front and rear side walls.

[0010] Furthermore, each of the water distribution tanks is connected to a bottom box on its bottom wall, and a guide plate is fixedly connected inside each bottom box. A sludge discharge pipe is fixedly connected to the bottom left side of each bottom box.

[0011] Furthermore, a second baffle is provided inside the front side of each of the sludge discharge pipes, and a handle is fixedly connected to the front side wall of each second baffle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through its designed locking block, support rod, placement groove, second spring, and baffle, can solve the problem of large-scale sewage leakage affecting the normal operation of the entire sewage treatment system, further amplifying the fault, increasing maintenance costs, and accident losses. After the locking block is fully inserted, under the elastic force of the first spring, the support rod pops out and inserts into the slot of the locking block, playing a lateral limiting role, thereby firmly installing the water distribution tank on the support plate. This effectively shortens maintenance time, reduces the impact on the normal operation of the denitrification deep bed filter, improves sewage treatment efficiency, and reduces maintenance costs and accident losses.

[0014] 2. The design, including the bottom tank, guide plates, sludge discharge pipe, and handle, addresses the issues that negatively impact the filter's treatment efficiency, necessitate more frequent backwashing, increase operating costs, and waste water resources. The guide plates, fixedly connected inside the bottom tank, guide the settled sludge, making it easier for it to accumulate towards the sludge discharge pipe. When sludge discharge is needed, pulling the handle moves the second baffle forward, opening the sludge discharge pipe. This effectively reduces equipment malfunctions and maintenance costs caused by pipe blockage, extends the service life of pipes and related equipment, and improves the efficiency and stability of the denitrification reaction.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 5The diagram shows a water distribution trough for a denitrification deep bed filter, comprising a tank body 1. Support plates 2 are fixedly connected to the left and right sides of the tank body 1. Water distribution troughs 3 are provided on the upper side walls of both support plates 2. The support plates 2 on the left and right sides of the tank body 1 support the bottom of the water distribution troughs 3 on both sides. Fixing plates 5 are fixedly connected to the left and right sides of the bottom wall of each water distribution trough 3. Two locking blocks 6 are fixedly connected to the bottom wall of each fixing plate 5. The fixing plates 5 are fixed to the bottom left and right sides of the water distribution trough 3, supporting and fixing the locking blocks 6 at the bottom, and connecting to the internal devices of the support plates 2 via the locking blocks 6.

[0027] Each support plate 2 has two outer shells 7 fixedly connected inside, which protect the internal device. Support rods 8 are slidably connected to the front and rear sides of the interior of each outer shell 7. A first spring 9 is fixedly connected to the rear side wall of every two support rods 8. The other end of every four first springs 9 is fixedly connected to the interior of one outer shell 7. Each outer shell 7 has a placement slot 10 inside. Two second springs 11 are fixedly connected to the bottom wall of the interior of each placement slot 10. A first baffle 12 is fixedly connected to the top of every two second springs 11. Each first baffle 12 is located inside a placement slot 10. The top of each first baffle 12 corresponds to the bottom wall of the locking block 6, and the slot of each locking block 6 corresponds to the top of the support rod 8. When installing the water distribution tank 3, the bottom locking block 6 is inserted into the placement slot inside the outer shell 7. In the slot 10, the bottom wall of the locking block 6 first contacts the top of the support rod 8 under the action of weight, so as to squeeze the support rod 8 to slide inside the housing 7. The support rod 8 squeezes the first spring 9 inside the housing 7. When the bottom wall of the locking block 6 enters half of the slot 10, the bottom wall of the locking block 6 contacts the first baffle 12, so that the first baffle 12 squeezes the second spring 11 to open the inside of the slot 10. When the locking block 6 is fully inserted into the slot 10, the squeezed first spring 9 will drive the support rod 8 to rebound, so that the top of the support rod 8 enters the slot of the locking block 6, so as to fix the locking block 6 in the inside of the slot 10 and fix the water distribution tank 3 to the upper side wall of the support plate 2.

[0028] As shown above, when disassembly is required, the worker first presses the support rods 8 on both the front and rear sides of the outer casing 7, causing the support rods 8 to slide inside the outer casing 7, thereby squeezing the first spring 9 inside the outer casing 7. At this time, the top of the support rod 8 will disengage from the slot of the locking block 6, pushing the locking block 6 upward and releasing the support rod 8 so that the support rod 8 rebounds through the first spring 9. At this time, the bottom of the locking block 6 will be placed on the top of the support rod 8 to support the bottom of the locking block 6. After the support rods 8 on both the left and right sides disengage from the locking block 6, the worker can remove the water distribution tank 3 from the support plate 2. The first baffle 12 inside the placement tank 10 will rebound under the action of the second spring 11 to seal the inside of the placement tank 10, preventing external impurities from entering the interior.

[0029] like Figure 1 - Figure 6 As shown, the two water distribution tanks 3 are connected to the left and right sides by water inlet pipes 4. The outer sides of the four water inlet pipes 4 are all connected to the inside of the left and right side walls of the tank body 1. Through the water inlet pipes 4, the sewage from the outside is transported into the inside of the water distribution tank 3.

[0030] Each distribution tank 3 has a support rod 13 fixedly connected to its internal top. The support rod 13 enhances the structural stability and prevents the distribution tank 3 from deforming due to water pressure or other factors during water intake, ensuring that the distribution tank 3 can receive wastewater normally and stably. Each distribution tank 3 has outlets 14 on both its front and rear side walls. The outlets 14 allow wastewater to flow out relatively evenly in the horizontal direction, ensuring that each area of ​​the denitrification deep bed filter receives a relatively balanced amount of wastewater, which is beneficial to improving the overall treatment effect of the filter.

[0031] like Figure 1 - Figure 7 As shown, each distribution tank 3 is connected to a bottom box 15. After sewage enters the distribution tank 3, impurities in the sewage mix with chemicals and other substances inside the distribution tank 3, causing the impurities to settle. The settled impurities fall into the bottom box 15 for initial collection. Each bottom box 15 is fixedly connected to a guide plate 16, and each bottom left side of each bottom box 15 is fixedly connected to a sludge discharge pipe 17. A second baffle 18 is installed inside the front side of each sludge discharge pipe 17, and a handle 19 is fixedly connected to the front side wall of each second baffle 18. The guide plate 16 inside the bottom box 15 guides the impurities entering the bottom box 15, causing them to move to the left and enter the sludge discharge pipe 17 on the bottom wall of the bottom box 15. When it is necessary to discharge the impurities, the operator pulls the handle 19 to remove the second baffle 18 behind the handle 19 from the inside of the sludge discharge pipe 17, and the impurities inside will be discharged by gravity.

[0032] It should be noted that this utility model is a water distribution tank for a denitrification deep bed filter.

[0033] Firstly, the support plates 2, which are fixedly connected to the left and right sides inside the pool body 1, provide the installation base for the water distribution tank 3. The fixing plates 5 on the left and right sides of the bottom wall of the water distribution tank 3 serve to connect and position the tank. The locking blocks 6 on the bottom wall of the fixing plates 5 cooperate with the outer shell 7 inside the support plates 2 to install the water distribution tank 3.

[0034] When the water distribution tank 3 needs to be installed, insert the locking block 6 into the position of the outer casing 7. During insertion, the locking block 6 presses against the first baffle 12, which in turn compresses the second spring 11 in the placement slot 10 and moves it downwards. At the same time, the slot of the locking block 6 pushes the support rod 8 to slide towards the front and rear sides inside the outer casing 7, compressing the first spring 9. When the locking block 6 is fully inserted, under the elastic force of the first spring 9, the support rod 8 pops out and inserts into the slot of the locking block 6, which acts as a lateral limit, thereby firmly installing the water distribution tank 3 on the support plate 2.

[0035] During the water distribution process, some sludge from the wastewater settles to the bottom of the distribution tank 3 and is collected through the bottom tank 15, which is connected to the bottom wall of the distribution tank 3. A guide plate 16 fixedly connected inside the bottom tank 15 guides the settled sludge, making it easier for the sludge to accumulate towards the sludge discharge pipe 17. When sludge discharge is needed, pulling the handle 19 moves the second baffle 18 forward, opening the passage of the sludge discharge pipe 17. Under gravity, the sludge accumulated in the bottom tank 15 is discharged through the sludge discharge pipe 17. After sludge discharge is complete, pushing the handle 19 resets the second baffle 18, closing the sludge discharge pipe 17 and preventing wastewater from flowing out of the sludge discharge pipe 17 during normal operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
