Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a microfiltration sedimentation component for an integrated tank for rural domestic wastewater treatment. Background Technology

[0002] Rural residents live in scattered locations, making it costly and difficult to cover the centralized construction of large-scale sewage treatment plant pipelines. Using integrated rural domestic sewage treatment tanks allows for local installation and on-site treatment, eliminating the need for complex pipeline transportation and enabling sewage to be treated in an orderly manner. At the same time, it reduces the land area required, adapts to the situation of scarce rural land resources, and reduces damage to the surrounding ecological environment.

[0003] Microfiltration sedimentation components are typically installed in integrated water treatment tanks. These components are the core pretreatment parts of the integrated tank, and their function is to remove suspended pollutants from wastewater, paving the way for subsequent biological treatment. Currently, in the use of existing microfiltration sedimentation components in integrated wastewater treatment tanks, the water flow usually directly impacts the bottom of the tank, which disrupts the stable hydraulic environment required for sedimentation. This stirs up the sludge that has already settled at the bottom of the tank, causing impurities that should have settled to resuspend and become ineffective for separation. This also reduces the efficiency of biological treatment and the sedimentation effect, affecting the continuous operation of the equipment. In view of this, this utility model is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a microfiltration sedimentation component for an integrated tank for rural domestic sewage treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A microfiltration sedimentation assembly for integrated tanks used for rural domestic sewage treatment includes a tank body and further includes:

[0007] The inlet and outlet are located on the side wall of the tank.

[0008] A first baffle and a second baffle are inclinedly arranged inside the tank. The first baffle and the second baffle are inclined in opposite directions. A first gap is provided between the first baffle and the inner wall of the tank. A second gap is provided between the second baffle and the inner wall of the other side of the tank.

[0009] A filter plate is inclinedly installed inside the tank, the inclination direction of the filter plate is consistent with the inclination direction of the first baffle plate, and a third gap is provided between the filter plate and the inner wall of the tank.

[0010] The flow guiding component is located in the third gap.

[0011] Preferably, the inner wall of the tank is fixedly connected to a fixed platform, and the flow guiding assembly includes a rotating shaft and a deflector plate rotatably connected to the fixed platform. The deflector plate is connected to the rotating shaft and has multiple circumferentially distributed components.

[0012] Furthermore, the bottom inner wall of the tank is provided with a vertically placed mesh plate, and the water inlet is located above the first baffle plate.

[0013] Furthermore, both the first baffle and the second baffle are provided with serrated grooves.

[0014] Preferably, the top of the tank is provided with an exhaust hole, the outer wall of the top of the tank is provided with an exhaust pipe corresponding to the exhaust hole, an annular plate is fixedly provided inside the exhaust hole, and a sealing plate that abuts against the annular plate is slidably connected inside the exhaust pipe.

[0015] Furthermore, a baffle is fixedly connected to the top of the exhaust pipe, a thin rod is fixedly connected to the baffle, a hollow tube is slidably connected to the outer wall of the thin rod, the hollow tube is fixedly connected to the sealing plate, and a spring is provided between the baffle and the sealing plate, the spring being sleeved between the thin rod and the hollow tube.

[0016] Preferably, the top of the tank has two openings, and end caps are threaded onto the openings.

[0017] Compared with the prior art, this utility model provides a microfiltration sedimentation component for an integrated tank for rural domestic sewage treatment, which has the following beneficial effects:

[0018] 1. The integrated microfiltration sedimentation component of this rural domestic sewage treatment tank, by setting a first baffle plate, a second baffle plate and a filter plate, forms a zigzag flow channel, which allows sewage to flow more evenly when it enters, reduces the overall flow speed, and avoids the water flow directly impacting the bottom of the tank, causing the sediment at the bottom to float up again, thus ensuring the sedimentation effect and efficiency and improving the overall working efficiency.

[0019] 2. The microfiltration sedimentation component of this integrated tank for rural domestic sewage treatment can separate small and large particles, suspended pollutants and other impurities through the filter plates. This reduces the agitation effect of large suspended solids on the sediment at the bottom when they fall, making the bottom of the tank more stable and improving sedimentation efficiency.

[0020] 3. The microfiltration sedimentation component of this integrated tank for rural domestic sewage treatment can discharge residual gas inside the tank by setting vent holes and vent pipes, thus avoiding excessive gas from causing tank deformation, leakage or rupture.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figures 1-5A microfiltration sedimentation assembly for an integrated tank for rural domestic sewage treatment includes a tank body 1, and an inlet 103 and an outlet 104 disposed on the side wall of the tank body 1. A first baffle plate 2 and a second baffle plate 202 are also inclinedly disposed inside the tank body 1, with opposite inclination directions. A first gap 201 is provided between the first baffle plate 2 and the inner wall of the tank body 1, and a second gap 203 is provided between the second baffle plate 202 and the inner wall of the tank body 1 on the other side. A filter plate 204 is inclinedly disposed inside the tank body 1, with the inclination direction of the filter plate 204 consistent with that of the first baffle plate 2. A third gap is provided between the filter plate 204 and the inner wall of the tank body 1. A flow guiding assembly is disposed at the third gap.

[0030] In this invention, before use, an inlet pipe is connected to the inlet 103 for water intake and an outlet pipe is connected to the outlet 104 for drainage. During use, water is injected through the inlet 103. After the water flows into the tank 1, it first falls onto the first baffle plate 2. Since the first baffle plate 2 is inclined, with its top positioned near the inlet 103, wastewater first flows onto the first baffle plate 2 and begins to flow through it. Then, it enters the second baffle plate 202 through the first gap 201, and similarly, falls onto the filter plate 204 through the second gap 203. Water first passes through filter plate 204 for filtration. Small impurities or particles pass directly through filter plate 204 and flow downwards. Under the action of filter plate 204, the water flow is dispersed and falls slowly. Larger particles and impurities move with filter plate 204 and then fall after passing through the flow guide component. The flow guide component allows larger particles and impurities to fall slowly, thus effectively preventing the water flow from directly impacting the bottom of tank 1 when it falls. This provides some protection for the sedimentation layer at the bottom of tank 1, thereby improving the efficiency of wastewater sedimentation. After sedimentation, the filtered water can be discharged through outlet 104.

[0031] It should be noted that the pores on the filter plate 204 are set to be relatively small, which will guide some water to flow slowly from the filter plate 204 and flow down through the filter plate 204. The height of the outlet 104 is also a certain distance from the bottom of the tank 1, so that the sediment at the bottom of the tank 1 will not be directly discharged from the outlet 104 along with the water flow.

[0032] Reference Figure 2 and Figure 3 The inner wall of the tank 1 is fixedly connected to a fixed platform 3. The flow guiding assembly includes a rotating shaft 301 rotatably connected to the fixed platform 3 and a deflecting plate 302. The deflecting plate 302 is connected to the rotating shaft 301 and has multiple circumferentially distributed components.

[0033] Reference Figure 2 and Figure 3 The bottom inner wall of the tank 1 is provided with a vertically placed mesh plate 303, and the water inlet 103 is located above the first baffle plate 2. When water is injected, the water flow will flow directly onto the first baffle plate 2.

[0034] In this invention, larger particles and impurities flow through the filter plate 204 to the agitator plate 302. When the agitator plate 302 rotates, it causes the particles and impurities to fall slowly, avoiding agitation of the sediment at the bottom. The vertically arranged mesh plate 303 at the bottom can block impurities, so that larger impurities are located on one side and smaller impurities are located on the other side. This effectively prevents the large impurities from agitating the sedimentation area of ​​the smaller impurities when they fall, resulting in higher sedimentation efficiency and improved work efficiency.

[0035] Reference Figure 3 and Figure 4 Both the first baffle plate 2 and the second baffle plate 202 are provided with serrated grooves 205. The serrated grooves 205 enable sewage to flow more easily on the first baffle plate 2 and the second baffle plate 202, thereby preventing small particles of impurities and dust from adhering to the first baffle plate 2 and the second baffle plate 202.

[0036] Reference Figures 1-5 The top of the tank body 1 is provided with an exhaust hole 402, and the outer wall of the top of the tank body 1 is provided with an exhaust pipe 4 corresponding to the exhaust hole 402. An annular plate 403 is fixedly provided inside the exhaust hole 402, and a sealing plate 404 that abuts against the annular plate 403 is slidably connected inside the exhaust pipe 4.

[0037] Reference Figure 5 A baffle 401 is fixedly connected to the top of the exhaust pipe 4. A thin rod 406 is fixedly connected to the baffle 401. A hollow tube 405 is slidably connected to the outer wall of the thin rod 406. The hollow tube 405 is fixedly connected to the sealing plate 404. A spring 407 is provided between the baffle 401 and the sealing plate 404. The spring 407 is sleeved between the thin rod 406 and the hollow tube 405.

[0038] Rural domestic sewage contains a large amount of organic pollutants. When these organic substances decompose, gases such as methane, carbon dioxide, and ammonia are produced. When sewage is injected into tank 1, it also carries oxygen and nitrogen from the air. The continuous accumulation of these gases will cause the pressure inside tank 1 to rise. If the pressure exceeds the pressure limit of tank 1, it may cause leakage, deformation, or even rupture. Therefore, this application provides an exhaust pipe 4 and an exhaust hole 402 at the top of tank 1. When the gas pressure inside tank 1 increases, it will push the sealing plate 404 to rise, so that it is no longer in contact with the annular plate 403. At this time, the gas can be discharged through the gap between the sealing plate 404 and the annular plate 403, and then through the exhaust hole 402 and the exhaust pipe 4. After the gas is discharged, the automatic reset of the spring 407 will cause the sealing plate 404 to abut against the annular plate 403 again, forming a seal again to ensure the sealing of the inside of tank 1. The hollow tube 405 and the thin rod 406 make it easy to move the sealing plate 404.

[0039] Reference Figures 1-3 The top of the tank body 1 is provided with two openings 101, and end caps 102 are threaded onto the openings 101. The openings 101 allow for convenient inspection and maintenance of the tank body 1, or auxiliary water intake operations. During normal use, the end caps 102 can seal the openings 101 for convenient normal use.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
