Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a rural wastewater treatment device based on laminar flow. Background Technology

[0002] Wastewater treatment is a significant environmental issue in rural areas. As rural living standards improve, the amount of wastewater generated is also increasing.

[0003] A search revealed that utility model CN221889275U discloses a laminar flow sewage treatment device for rural sewage treatment, belonging to the field of sewage treatment technology. It includes a base plate on which a sewage filter tank and a solar battery are fixedly connected. The base plate of the sewage filter tank has drawer slots on its front side, and multiple drawer frames are slidably and airtightly installed inside each drawer slot. Each drawer frame has multiple perforations at its bottom. This utility model, by setting drawer frames, allows for the replacement of the first, second, and third filter layers by removing them, as the drawer frames are placed inside. When the drive motors are started, the power output of the two drive motors causes the displacement block to move through the rotation of the threaded rod. The displacement block then moves the drawer frame on the back of the second connecting block, automatically removing the drawer frame for timely replacement of the filter layers, thus helping to maintain the filtration effect within the sewage filter tank over a long period.

[0004] However, this type of wastewater treatment often suffers from low treatment efficiency, difficult maintenance, and the generation of odors. In particular, how to effectively prevent the emission of odors during the treatment process, and how to facilitate convenient and quick cleaning and replacement of internal components during maintenance, are urgent problems that need to be solved in current rural wastewater treatment equipment. Utility Model Content

[0005] The purpose of this invention is to address the problems of low treatment efficiency, difficult maintenance, and odor generation in existing sewage treatment methods. In particular, effectively preventing odor emission during treatment and facilitating convenient and quick cleaning and replacement of internal components during maintenance are shortcomings that current rural sewage treatment devices urgently need to solve. Therefore, this invention proposes a laminar flow-based rural sewage treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rural sewage treatment device based on laminar flow includes a treatment tank with an open top. An inlet pipe is fixedly inserted through the top side of the treatment tank, and a drain pipe is fixedly inserted through the bottom side of the treatment tank. A rectangular groove is formed on the inner wall of the treatment tank, and a connected inclined groove is formed on the bottom inner wall of the rectangular groove. The inclined groove is inclined. A placement groove is formed on the top of the treatment tank, and an odor-proof component is installed inside the rectangular groove to prevent odor from being emitted.

[0008] The inner wall of one side of the processing box is provided with a clamping assembly for clamping the water inlet pipe;

[0009] The placement slot is equipped with a sealing component for sealing the processing box.

[0010] The processing box has multiple mounting slots on one side, and a mounting frame slides through the inside of the mounting slot. A filter plate is fixedly installed inside the mounting frame. A rectangular cavity is formed on the bottom inner wall of the placement slot, and a limiting component for limiting the mounting frame is provided inside the rectangular cavity.

[0011] In one possible design, the odor-proof component includes a support plate with a conical block fixedly installed at the top center. Limiting rods are fixedly connected to the four top corners of the support plate. The top of the limiting rods slides through into the interior of the placement groove. A limiting block is fixedly connected to the top of the limiting rods. A compression spring is provided between the bottom of the limiting block and the bottom inner wall of the placement groove. The compression spring is sleeved on the limiting rods. The top and bottom of the compression spring abut against the bottom of the limiting block and the bottom inner wall of the placement groove through spring seats.

[0012] In one possible design, the clamping assembly includes two symmetrically arranged slide grooves formed on one side of the inner wall of the processing tank. A slider is slidably connected inside the slide groove. A tension spring is provided between one side of the slider and one side of the inner wall of the slide groove. Both ends of the tension spring abut against one side of the slider and one side of the inner wall of the slide groove through spring seats. An arc-shaped clamp is fixedly connected to one side of the slider. The two arc-shaped clamps are used to clamp the water inlet pipe.

[0013] In one possible design, the sealing assembly includes a limiting plate that snaps into the placement slot, a cover plate that is fixedly connected to the top of the limiting plate, the cover plate being fixedly connected to the processing box by a plurality of fixing screws, and a plurality of clearance slots that are provided at the bottom of the limiting plate for making way for the limiting block.

[0014] In one possible design, the limiting component includes a horizontal plate slidably connected inside a rectangular cavity, a handle fixedly connected to the top side of the horizontal plate, two symmetrically arranged insert rods fixedly connected to the bottom of the horizontal plate, two symmetrically arranged insertion holes opened inside the mounting frame, the insert rods engaging with the insertion holes, and a pull handle fixedly connected to one side of the mounting frame.

[0015] In one possible design, two symmetrically arranged push blocks are fixedly connected to one side of the bottom of the limiting plate. The push blocks are used in conjunction with the arc-shaped clamps to push the two arc-shaped clamps closer to each other.

[0016] In one possible design, a triangular inclined plate is fixedly installed on the bottom inner wall of the processing box.

[0017] In this application, during use, sewage is sent into the interior of the treatment tank through the inlet pipe. At this time, the sewage pushes the support plate downward, which in turn moves the conical block downward. The support plate then moves the external limiting rod downward, which in turn moves the limiting block downward. The limiting block compresses the spring, and the support plate moves downward from the top inner wall of the rectangular groove. At this time, there is a gap between the support plate and the rectangular groove, allowing the sewage to be discharged downward normally. When the sewage stops being discharged, the support plate moves upward and resets, thus preventing odor from being emitted.

[0018] After being filtered through multiple filter plates, the wastewater enters the lower part of the treatment tank, slides out through the inclined surface of the triangular inclined plate, and is finally discharged through the drain pipe. When maintenance is required, the fixing screws can be unscrewed, and the cover plate and limit plate can be removed to allow maintenance of the internal device. The two push blocks move up with the cover plate and no longer press against the arc-shaped clamping plate. At this time, the arc-shaped clamping plate and the slider move away from each other under the tension of the tension spring, allowing the water inlet pipe to make way and be removed.

[0019] Furthermore, at this point, the rectangular cavity does not need to be blocked. The handle located on the inner wall of one side of the rectangular cavity can be pulled upwards. The handle causes the horizontal plate to move upwards, and the horizontal plate causes the insertion rod to move upwards. The insertion rod moves out of the insertion hole. At this point, the braking state of the mounting frame can be released, and the mounting frame can be moved out by pulling the handle, allowing the filter plate to be cleaned.

[0020] Beneficial effects: By setting up an odor-proof component, when sewage enters the treatment tank through the inlet pipe, the sewage pushes the support plate and conical block downward, creating a gap between the support plate and the rectangular trough, allowing the sewage to drain downward normally; when the sewage stops draining, the support plate moves upward and resets under the action of the compression spring, at which point the support plate and the rectangular trough fit tightly together, effectively preventing the emission of odors and improving the environmental quality of the surrounding rural areas.

[0021] When maintenance is required, simply unscrew the fixing screws to remove the cover and limit plate, allowing for maintenance of the internal components. Simultaneously, the two push blocks move upwards with the cover, no longer pressing against the arc-shaped clamp. The arc-shaped clamp and slider move away from each other under the tension of the spring, creating space for the water inlet pipe and facilitating its removal, greatly improving maintenance convenience.

[0022] The device of this application is equipped with a detachable mounting frame, in which a filter plate is fixedly installed. When it is necessary to clean the filter plate, simply pull the handle upwards, causing the horizontal plate and the insert rod to move upwards, so that the insert rod moves out of the insertion hole, releasing the braking state of the mounting frame. Then, the mounting frame can be removed by pulling the handle, which facilitates the cleaning of the filter plate, extends the service life of the filter plate, and ensures the effect of sewage treatment.

[0023] Triangular inclined plates are fixedly installed on the bottom inner wall of the treatment tank. After being filtered by multiple filter plates, the sewage enters the bottom of the treatment tank and can slide smoothly out through the inclined surface of the triangular inclined plates. Finally, it is discharged through the drain pipe, which improves drainage efficiency and avoids sewage accumulation in the treatment tank. Attached Figure Description

[0031] 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.

[0032] Example 1

[0033] Reference Figure 1-6 A treatment device, the implementation process of which is based on laminar flow rural sewage treatment device, is as follows: The treatment tank 1 adopts a cuboid structure with an open top. An inlet pipe 2 is welded to the top left side of the tank, and a drain pipe 5 is welded to the bottom left side. A rectangular groove 17 with a depth of approximately 5 cm is machined on the inner wall of the treatment tank 1, and its bottom connects to an inclined groove 16 at a 45-degree angle. A placement groove 11 with a depth of 10 cm is opened at the top of the treatment tank 1. Three equally spaced mounting grooves 15 are machined on the right side wall. Mounting frames 9 are slidably inserted into the mounting grooves 15, and stainless steel filter plates 28 with different apertures are embedded in the mounting frames 9. A rectangular cavity 26 penetrating the side wall is opened at the bottom of the placement groove 11.

[0034] The odor-proof component is installed inside the rectangular groove 17: the support plate 8 is sized to match the opening of the rectangular groove 17, and a conical block 7 is welded to the center of its top surface. Four limiting rods 25 are welded vertically at the four corners. The top of the limiting rod 25 passes through the bottom of the placement groove 11, and the end is welded with a limiting block 24 with a diameter larger than the rod diameter. Each limiting rod 25 is fitted with a compression spring 23, and the two ends of the spring are respectively supported by welded spring seats against the bottom of the limiting block 24 and the bottom surface of the placement groove 11.

[0035] The clamping assembly is located on the inner left side of the processing box 1: two symmetrical grooves 27 each contain a slider 19, and a tension spring 22 connects the slider 19 to the inner end face of the groove 27. An arc-shaped clamping plate 21 is welded to the outer end of the slider 19, and its curvature matches the outer diameter of the water inlet pipe 2. Under normal conditions, the tension of the tension spring 22 keeps the two arc-shaped clamping plates 21 in a clamped state.

[0036] The sealing assembly includes a limiting plate 6 and a cover plate 4: the limiting plate 6 is embedded in the placement groove 11, and the cover plate 4 is fixed to its top surface with bolts. The two are locked to the top of the processing box 1 by four evenly distributed fixing screws 3. The bottom surface of the limiting plate 6 has four clearance grooves 18 corresponding to the positions of the limiting blocks 24, and the depth is greater than the height of the limiting blocks 24. Two pushing blocks 20 are also welded to the bottom surface of the limiting plate 6, and their inclined surfaces face the outer edges of the two arc-shaped clamps 21.

[0037] This application can be used in the field of wastewater treatment, or in other fields applicable to this application.

[0038] Example 2

[0039] refer to Figure 1-6 An improvement on Example 1: A laminar flow-based rural sewage treatment device, applied to the sewage treatment field, with a limiting component placed in a rectangular cavity 26; a horizontal plate 13 is slidably embedded in the cavity, with a handle 12 welded to the right side of its top surface and two insertion rods 14 vertically welded to its bottom surface. Insertion holes 29 are opened at corresponding positions on the mounting frame 9; when the horizontal plate 13 is pressed down, the insertion rods 14 are inserted into the insertion holes 29 to lock the mounting frame 9. A pull handle 30 is welded to the outer end of the mounting frame 9.

[0040] A triangular inclined plate 10 is welded to the center of the bottom of the treatment box 1, and the slope of its inclined surface points in the direction of the drain pipe 5.

[0041] During implementation, wastewater flows into the impact cone block 7 through the inlet pipe 2, pushing the support plate 8 downward to compress the spring 23. The wastewater then flows into the tank through the gap between the support plate 8 and the rectangular groove 17. When the water flow stops, the compression spring 23 pushes the support plate 8 back to its original position, sealing the rectangular groove 17 and preventing odor from escaping. After being filtered by the multi-layer filter plate 28, the wastewater is discharged from the drain pipe 5 along the inclined plane of the triangular inclined plate 10.

[0042] During maintenance, loosen the fixing screw 3, lift the cover plate 4 to move the limiting plate 6 upward, push the block 20 away from the arc-shaped clamp 21, and pull the slider 19 with the tension spring 22 to loosen the inlet pipe 2. At the same time, the limiting block 24 enters the relief groove 18, releasing the limitation on the support plate 8. Lift the handle 12 to move the insertion rod 14 away from the insertion hole 29, and pull the handle 30 to remove the mounting frame 9 to replace the filter plate 28.

[0043] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
