Abstract
Description
Technical Field
[0001] This utility model relates to the field of inclined plate sedimentation technology, and in particular to a uniformly distributed water inlet structure for an inclined plate sedimentation system. Background Technology
[0002] Inclined plate sedimentation is a commonly used solid-liquid separation technology. By setting up inclined plates, the sedimentation area and particle settling path are increased, effectively improving sedimentation efficiency. Wastewater flows slowly between the inclined plates, and suspended particles settle to the plate surface under gravity and gradually slide down to the bottom of the tank, achieving the separation of solids and liquids. In order to ensure the stability and efficiency of the sedimentation process, the uniformly distributed influent structure is an important part of the inclined plate sedimentation system. It can achieve uniform distribution of influent flow, promote smooth water flow, and thus ensure the uniformity of hydraulic conditions in the sedimentation zone and optimize the sedimentation effect.
[0003] Existing uniformly distributed influent structures generally suffer from insufficient buffering of sewage impact in practical use. They typically lack effective buffering mechanisms specifically designed to weaken the instantaneous kinetic energy of the influent, causing severe disturbance to the sewage before it enters the sedimentation zone, thus affecting the subsequent sedimentation effect. At the same time, existing influent structures mostly adopt a unidirectional guiding method, which cannot achieve flow regulation and multi-level diffusion according to changes in water flow. Especially under high flow or intermittent influent conditions, the lack of multi-stage buffering and uniformly distributed guiding structures will exacerbate short-circuiting and flow deviation problems, reducing the overall efficiency of the sedimentation system.
[0004] Therefore, addressing the problems of existing uniformly distributed influent structures, this invention constructs a multi-stage buffering and flow guiding structure by incorporating a second buffer block comprising a buffer slide plate, piston rod, buffer spring, buffer tube, and damping fluid, and a first buffer block with staggered upper and lower buffer plates. This solves the problems of insufficient effective buffering in existing uniformly distributed influent structures, leading to severe sewage impact, uneven water flow distribution, and low sedimentation efficiency. This structure effectively absorbs the kinetic energy of the influent, slows the flow velocity, achieves gradual pressure reduction and lateral equalization of the water flow, and improves the operational stability and treatment efficiency of the inclined plate sedimentation system. Utility Model Content
[0005] In order to overcome the problem that existing uniformly distributed influent structures generally lack effective buffer devices, making it difficult to weaken the impact force of sewage inflow, easily causing disturbance in the sedimentation zone and affecting the sedimentation effect, and that they mostly adopt a single guidance method without multi-stage buffering and uniform diversion design, they are prone to short-flow and flow deviation under high flow or intermittent influent conditions, reducing the system's operating efficiency.
[0006] The technical solution of this utility model is as follows: a uniformly distributed water inlet structure for an inclined plate sedimentation system, including an installation block, a connecting block, and a guide plate; a first buffer block is fixedly connected to the back of the installation block, the connecting block is fixedly connected to the side of the first buffer block away from the installation block, a second buffer block is fixedly connected to the side of the connecting block away from the first buffer block, the guide plate is fixedly connected to the inner wall of the connecting block, the guide plate is fixedly connected to the side of the first buffer block away from the installation block, and the guide plate is fixedly connected to the side of the second buffer block close to the connecting block.
[0007] Preferably, the mounting block, the first buffer block, and the connecting block are an integrated structure, the second buffer block is a square frame structure, and the guide plate is composed of multiple sets of strip plates.
[0008] Preferably, the mounting block has mounting holes inside, which are symmetrically distributed at the four corners of the front of the mounting block. A water outlet is fixedly connected inside the mounting block and is installed at equal intervals on the front of the mounting block.
[0009] Preferably, an upper buffer plate and a lower buffer plate are fixedly connected to the inner sidewall of the first buffer block. The upper buffer plate is located near the mounting block and is fixedly connected to the top of the first buffer block. The lower buffer plate is located near the connecting block and is fixedly connected to the bottom of the first buffer block.
[0010] Preferably, a side buffer plate is fixedly connected to the inner wall of the second buffer block, and the side buffer plates are symmetrically and alternately distributed near the connecting block. A buffer slide plate is slidably connected inside the second buffer block, and the buffer slide plates are symmetrically and alternately distributed away from the connecting block. A baffle is fixedly connected to the side of the buffer slide plate near the side buffer plate.
[0011] Preferably, the baffle is slidably connected inside the second buffer block, and a piston rod is fixedly connected to the side of the buffer slide plate near the baffle. The piston rod is symmetrically installed near both ends of the buffer slide plate, and a buffer spring is sleeved on the outside of the piston rod.
[0012] Preferably, one end of the buffer spring is fixedly connected to the side of the buffer slide near the baffle, and the other end of the buffer spring is fixedly connected to the inside of the second buffer block. The second buffer block has a buffer tube fixedly connected inside, and the buffer tubes are symmetrically installed near the buffer slide. The piston rod is slidably connected to the inner wall of the buffer tube, and the inside of the buffer tube is filled with damping fluid.
[0013] The beneficial effects of this utility model are:
[0014] When the device is put into use, the sewage first enters the second buffer block and, under the impact of the sewage, pushes the buffer slide plate to slide closer to the connecting block. The buffer slide plate continuously compresses the piston rod and the buffer spring, causing the piston rod to move towards the buffer tube. The damping fluid flows through the micro-holes on the piston rod, forming a damping effect and achieving initial buffering. At the same time, the buffer spring further absorbs the remaining kinetic energy, slows down the movement of the buffer slide plate, and effectively buffers the impact of sewage.
[0015] After the sewage flows through the buffer slide, it continues to flow in the second buffer block and then through the side buffer plates. Because the side buffer plates are arranged in an alternating manner, the water flow is further disturbed and reduced, and the water flow is guided into the connecting block. In the connecting block, the guide plates set on the inner wall guide the sewage in a direction, so that it is evenly distributed to all parts of the connecting block, thereby reducing the impact and optimizing the flow pattern.
[0016] After the sewage flows out of the connecting block, it enters the first buffer block. The first buffer block is equipped with staggered upper and lower buffer plates, forming a labyrinthine water inlet channel, which performs deep buffering and diversion treatment on the water flow. The sewage first impacts the lower buffer plate, forming a lower buffer and achieving preliminary lateral distribution. Subsequently, it impacts the upper buffer plate, completing the upper buffer and further lateral distribution. Finally, the sewage, after multi-stage buffering treatment, flows into the installation block and is evenly injected into the external inclined plate sedimentation tank through the outlet, effectively reducing water inlet disturbance and improving sedimentation efficiency.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-7 This utility model provides a technical solution: a uniformly distributed water inlet structure for an inclined plate sedimentation system, including an installation block 1, a connecting block 3, and a guide plate 5; a first buffer block 2 is fixedly connected to the back of the installation block 1, the connecting block 3 is fixedly connected to the side of the first buffer block 2 away from the installation block 1, a second buffer block 4 is fixedly connected to the side of the connecting block 3 away from the first buffer block 2, the guide plate 5 is fixedly connected to the inner wall of the connecting block 3, the guide plate 5 is fixedly connected to the side of the first buffer block 2 away from the installation block 1, and the guide plate 5 is fixedly connected to the side of the second buffer block 4 close to the connecting block 3.
[0027] The mounting block 1, the first buffer block 2, and the connecting block 3 are integrated structures, the second buffer block 4 is a square frame structure, and the guide plate 5 is composed of multiple strip plates. The integrated structure effectively reduces the connection gaps between components and improves the structural stability and overall sealing.
[0028] The mounting block 1 has mounting holes 101 inside, which are symmetrically distributed at the four corners of the front of the mounting block 1. The mounting block 1 has outlets 102 fixedly connected inside, and the outlets 102 are equidistantly installed on the front of the mounting block 1. The equidistantly distributed outlets 102 help to evenly discharge the buffered and evenly distributed sewage into the inclined plate sedimentation tank, avoiding the impact or flow deviation problems caused by local concentrated drainage.
[0029] An upper buffer plate 201 and a lower buffer plate 202 are fixedly connected to the inner wall of the first buffer block 2. The upper buffer plate 201 is located near the mounting block 1 and is fixedly connected to the top of the first buffer block 2. The lower buffer plate 202 is located near the connecting block 3 and is fixedly connected to the bottom of the first buffer block 2, forming a staggered buffer structure that effectively constructs a labyrinthine water flow channel, allowing the water flow to be fully buffered and evenly distributed before entering the inclined plate sedimentation tank, thereby effectively reducing water flow disturbance.
[0030] A side buffer plate 401 is fixedly connected to the inner wall of the second buffer block 4. The side buffer plates 401 are symmetrically and alternately distributed near the connecting block 3. A buffer slide plate 402 is slidably connected inside the second buffer block 4. The buffer slide plates 402 are symmetrically and alternately distributed away from the connecting block 3. A baffle 403 is fixedly connected to the side of the buffer slide plate 402 near the side buffer plate 401. The side buffer plate 401 can disturb and decelerate the water flow at multiple angles in the early stage of sewage entry, so as to achieve initial buffering.
[0031] The baffle 403 is slidably connected inside the second buffer block 4. A piston rod 404 is fixedly connected to the side of the buffer slide plate 402 near the baffle 403. The piston rod 404 is symmetrically installed near both ends of the buffer slide plate 402. A buffer spring 405 is sleeved on the outside of the piston rod 404. The buffer spring 405 can be compressed and stored when the water flow impacts the buffer slide plate 402, and releases its elastic force after the impact weakens, so that the buffer slide plate 402 and the baffle 403 return to their original positions, thereby forming a recoverable dynamic buffering process.
[0032] One end of the buffer spring 405 is fixedly connected to the side of the buffer slide plate 402 near the baffle 403, and the other end of the buffer spring 405 is fixedly connected to the inside of the second buffer block 4. A buffer tube 406 is fixedly connected inside the second buffer block 4. The buffer tube 406 is symmetrically installed near the buffer slide plate 402. The piston rod 404 is slidably connected to the inner wall of the buffer tube 406. The inside of the buffer tube 406 is filled with damping fluid 407. When the sewage impact pushes the buffer slide plate 402 and drives the piston rod 404 to slide, the damping fluid 407 forms resistance through the holes on the piston rod 404, thereby realizing liquid damping buffering and further reducing the transmission speed of the impact force.
[0033] Working principle: According to Figures 1 to 2 As shown, when the device is ready for use, first, the whole device is placed in the working area and installed in the inlet area of the external inclined plate sedimentation tank through the mounting hole 101. Then, the wastewater to be settled is introduced into the device to achieve preliminary inlet buffering and uniform distribution preparation.
[0034] according to Figures 3 to 7As shown, when the device is put into use, the sewage first enters the second buffer block 4 and, under the impact of the sewage, pushes the buffer slide plate 402 to slide closer to the connecting block 3. During the sliding process of the buffer slide plate 402, the buffer slide plate 402 continuously compresses the piston rod 404 and the buffer spring 405, causing the piston rod 404 to move towards the buffer tube 406. The damping fluid 407 flows through the micropores on the piston rod 404, using the incompressibility of the liquid to form a damping effect and achieve initial buffering. At the same time, under the elastic force of the buffer spring 405, the remaining kinetic energy is further absorbed, slowing down the movement of the buffer slide plate 402 and effectively buffering the impact of the sewage. During the buffering process, the baffle 403 slides synchronously with the buffer slide plate 402, effectively preventing the sewage from directly washing the piston rod 404 and the buffer spring 405, thus playing a protective role.
[0035] according to Figures 3 to 6 As shown, after the sewage flows through the buffer slide plate 402, the sewage continues to flow in the second buffer block 4 and passes through the side buffer plate 401. Since the side buffer plate 401 is arranged in an alternating manner, it further disturbs and reduces the water flow and guides the water flow into the connecting block 3. In the connecting block 3, the guide plate 5 set on the inner wall guides the sewage in a direction, so that it is evenly distributed to all parts of the connecting block 3, thereby reducing the impact and optimizing the flow pattern.
[0036] according to Figures 1 to 4 As shown, after the sewage flows out of the connecting block 3, it enters the first buffer block 2. The first buffer block 2 is equipped with staggered upper buffer plates 201 and lower buffer plates 202, forming a labyrinthine water inlet channel, which performs deep buffering and diversion treatment on the water flow. The sewage first impacts the lower buffer plate 202, forming a lower buffer and achieving preliminary lateral distribution. Subsequently, it impacts the upper buffer plate 201, completing the upper buffer and further lateral distribution. Finally, the sewage after multi-stage buffering treatment flows into the installation block 1 and is evenly injected into the external inclined plate sedimentation tank through the outlet 102, effectively reducing water inlet disturbance and improving sedimentation efficiency.
[0037] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
