Description

Technical Field

[0001] This utility model relates to the field of high-temperature and high-pressure heating and recovery technology for sewage, specifically a sewage treatment, recovery, depressurization, buffering, and stabilization device. Background Technology

[0002] Wastewater treatment and recycling pressure reduction and buffer stabilization device is a special equipment used in wastewater treatment systems. It is mainly used for pressure regulation, buffering of impact force and stabilization of fluid output in the process of high-pressure or high-flow wastewater recycling, so as to ensure the safe and efficient operation of the system. Its core function is to reduce water flow pressure fluctuations, prevent pipelines or subsequent treatment equipment from being damaged due to sudden pressure changes, and optimize wastewater recycling efficiency.

[0003] Currently, there are many types of pressure-reducing buffer devices. For example, Chinese Patent No. CN202023063799.9 describes a buffer device for reducing pressure on the inlet pipe of a water tank. This patent includes a pressure-reducing device, a water tank, a first inlet pipe, and a second inlet pipe. Flanges are provided at both ends of the pressure-reducing device. The water tank is located beside the pressure-reducing device. One end of the first inlet pipe is mounted on the water tank, and the other end is connected to one of the flanges. The first inlet pipe is connected to both the pressure-reducing device and the water tank. One end of the second inlet pipe is connected to the other flange. Furthermore, the second water inlet pipe is connected to the pressure reducing device. In this invention, the pressure reducing device can reduce the pressure of the tap water transported by the second water inlet pipe. The tap water is depressurized and buffered in the pressure reducing device, which reduces the water pressure of the tap water, thereby reducing the water pressure in the first water inlet pipe and reducing the pressure of the tap water flowing into the water tank. However, in actual use, due to the limited pressure reducing capacity of the device, it cannot perform multi-stage pressure reduction. As a result, when encountering a large volume of water or a water flow mixed with high temperature and pressure, it cannot stably reduce the pressure and the pressure drops suddenly. In severe cases, it may even cause personal injury or death due to pipe wall rupture. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a wastewater treatment and recycling decompression buffer stabilization device, which has the advantage of multi-stage decompression and solves the problems of unstable decompression and sudden pressure drop in the existing device.

[0005] To achieve the above-mentioned multi-stage pressure reduction objective, this utility model provides the following technical solution: a wastewater treatment and recycling pressure reduction buffer stabilization device, including an airbag-type buffer pressure stabilizing water tank, a graded pressure reducer, an inlet pipe and an outlet pipe. The right side of the airbag-type buffer pressure stabilizing water tank is fixedly connected to the left side of the graded pressure reducer through the inlet pipe. The right side of the graded pressure reducer is connected to the outlet pipe. Pressure reduction buffer mechanisms are provided on both the inner top wall and the inner bottom wall of the graded pressure reducer.

[0006] Each pressure-reducing buffer mechanism includes two first fixed blocks and two connecting seats. Two first fixed blocks are fixedly installed on the inner top wall of the graded pressure reducer. A telescopic sleeve rod assembly is provided at the bottom of each of the two first fixed blocks. A first return spring is fixedly installed at the bottom of each of the two first fixed blocks and outside the telescopic sleeve rod assembly. A second fixed block is fixedly connected to the bottom end of each of the first and second fixed blocks on the same side. A connecting seat is fixedly installed on each of the connecting seats. A transmission rod is hinged to each of the connecting seats. The connecting ends of the two transmission rods on the same side are respectively connected to the connecting ends on the upper and lower sides of the connecting seat, and the connection relationship is hinged. A limiting slide plate connected to the inner top wall of the graded pressure reducer is fixedly installed at the opposite end of each of the two connecting seats. A trapezoidal block is fixedly installed at the near end of each of the two connecting seats. Two second return springs are provided between the two trapezoidal blocks. A movable plate that fits against the inner wall of the graded pressure reducer is fixedly connected to the bottom of each of the two second fixed blocks. A pressure plate is provided at the bottom of the movable plate. A flow-limiting block is provided on the pressure plate.

[0007] Furthermore, an airbag-type buffer pressure stabilizing tank is installed at the front end of the inlet pipe, with a built-in automatically retractable rubber airbag.

[0008] Furthermore, the telescopic sleeve assembly includes an outer rod fixed to the first fixing block, an inner rod nested inside the outer rod, and an anti-detachment ring to prevent the inner rod from detaching. The bottom end of the inner rod is fixedly connected to the second fixing block.

[0009] Furthermore, the inner top wall of the graded pressure reducer has two inclined sliding grooves adapted to the limiting slide plate, and the inner wall of the inclined sliding groove is slidably connected to the outer wall of the limiting slide plate.

[0010] Furthermore, the two second return springs are located on the front and rear sides of the two first return springs respectively, and the two do not contact each other.

[0011] Furthermore, limiting strips connected to the inner wall of the graded pressure reducer are provided on both the left and right sides of the movable plate.

[0012] Furthermore, the inner walls of both sides of the graded pressure reducer are provided with guide grooves that are adapted to the limiting strip, and the inner wall of the guide groove and the outer wall of the limiting strip are in a sliding connection relationship.

[0013] Furthermore, the connection ends of the graded pressure reducer to the inlet pipe and the outlet pipe are all fixed by bolts and nuts, and the connection surfaces are provided with sealing rings.

[0014] Furthermore, the internal components of the airbag-type buffer pressure-stabilizing water tank, the graded pressure reducer, the inlet pipe, and the outlet pipe are all interconnected.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This wastewater treatment and recycling pressure reduction and buffer stabilization device, through the setting of a pressure reduction and buffer mechanism, firstly, when the water flow pressure pushes the flow limiting block, the movable plate will drive the second fixed block to compress the first reset spring and the telescopic sleeve assembly. Then, the transmission rod pushes the limiting slide plate on the connecting seat to slide along the inclined slide groove, so that the two trapezoidal blocks separate and stretch the second reset spring, forming a multi-stage buffer. Finally, the extension force of the second reset spring can assist the trapezoidal blocks to reset, shortening the system recovery time. Thus, this mechanism can effectively resolve the situation where the pipe is easily burst when the water flow pressure is too high. At the same time, an airbag-type buffer pressure stabilizing water tank and a staged pressure reducer are installed in parallel on the inlet pipe. When the pressure changes suddenly, the expansion or contraction volume can be automatically adjusted to buffer and stabilize the pressure. It has strong practicality and safety.

[0021] 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.

[0022] Please see Figure 1-3 The wastewater treatment and recycling pressure reduction buffer stabilization device in this embodiment includes an airbag-type buffer pressure stabilizing water tank 1, a graded pressure reducer 2, an inlet pipe 5, and an outlet pipe 3. The right side of the airbag-type buffer pressure stabilizing water tank 1 is fixedly connected to the left side of the graded pressure reducer 2 through the inlet pipe 5. The right side of the graded pressure reducer 2 is connected to the outlet pipe 3. Pressure reduction buffer mechanisms 4 are provided on the inner top wall and inner bottom wall of the graded pressure reducer 2.

[0023] Each pressure-reducing buffer mechanism 4 includes two first fixing blocks 401 and two connecting seats 407. Two first fixing blocks 401 are fixedly installed on the inner top wall of the staged pressure reducer 2. A telescopic sleeve assembly 402 is provided at the bottom of each of the two first fixing blocks 401. A first return spring 403 is fixedly installed at the bottom of each of the two first fixing blocks 401 and outside the telescopic sleeve assembly 402. A second fixing block 404 is fixedly connected to the bottom end of each first return spring 403 and the telescopic sleeve assembly 402. A connecting seat 405 is fixedly installed on both the first fixing block 401 and the second fixing block 404 on the same side. A transmission rod 406 is hinged to each connecting seat 405. The connecting ends of the two transmission rods 406 on the same side are respectively connected to the connecting ends on the upper and lower sides of the connecting seat 407, and the connection relationship is hinged. A limiting slide plate 408 connected to the inner top wall of the staged pressure reducer 2 is fixedly installed at the opposite end of each of the two connecting seats 407. Trapezoidal blocks 409 are fixedly installed at one end of each of the two adjacent trapezoidal blocks 409. Two second return springs 410 are arranged between the two trapezoidal blocks 409. The bottom of the two second fixed blocks 404 is fixedly connected to a movable plate 411 that fits against the inner wall of the stage pressure reducer 2. A pressure plate 412 is arranged at the bottom of the movable plate 411. A flow limiting block 413 is arranged on the pressure plate 412. When water pressure pushes the flow limiting block 413, the movable plate 411 will drive the second fixed blocks 404 to compress the first return spring 403 and the telescopic sleeve assembly 402. Then, the transmission rod 406 pushes the limiting slide plate 408 on the connecting seat 407 to slide along the inclined slide groove, so that the two trapezoidal blocks 40 separate and stretch the second return springs 410, forming a multi-stage buffer. Finally, the extension force of the second return springs 410 can assist the trapezoidal blocks 409 to reset, shortening the system recovery time. Thus, this mechanism can effectively resolve the situation where the pipe is easily burst when the water pressure is too high. It has strong practicality and safety.

[0024] In the implementation of the case, the telescopic sleeve assembly 402 includes an outer rod fixed to the first fixing block 401, an inner rod nested inside the outer rod, and an anti-detachment ring to prevent the inner rod from falling out. The bottom end of the inner rod is fixedly connected to the second fixing block 404. This design can stably connect the first fixing block 401 and the second fixing block 404 to prevent them from shifting or tilting.

[0025] In the implementation of the case, each of the two connecting seats 407 has a fixed limiting slide plate 408 that is connected to the inner top wall of the graded pressure reducer 2. The inner top wall of the graded pressure reducer 2 has two inclined slide grooves that are adapted to the limiting slide plate 408. The inner wall of the inclined slide groove is slidably connected to the outer wall of the limiting slide plate 408. The left and right sides of the movable plate 411 are provided with limiting strips that are connected to the inner wall of the graded pressure reducer 2. The inner walls of the left and right sides of the graded pressure reducer 2 are provided with guide grooves that are adapted to the limiting strips. The inner wall of the guide groove is slidably connected to the outer wall of the limiting strip. Thus, the cooperation between the inclined slide groove and the limiting slide plate 408 ensures the linear movement of the pressure reducing buffer mechanism 4 and avoids deviation. At the same time, the limiting strip and the guide groove further restrict the displacement direction of the movable plate 411 and improve stability.

[0026] In the case implementation, the airbag-type buffer pressure stabilizing water tank 1 and the graded pressure reducer 2 are connected in parallel through pipes. The connection ends of the graded pressure reducer 2 with the inlet pipe 5 and the outlet pipe 3 are fixed with bolts and nuts, and the connection surface is equipped with a sealing ring. This design can ensure the tightness and sealing of the connection between the graded pressure reducer 2 and the inlet pipe 5 and the outlet pipe 3.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, water flows into the airbag-type buffer and pressure-stabilizing water tank 1. At the same time, when the water pressure pushes the flow limiting block 413, the movable plate 411 will drive the second fixed block 404 to compress the first reset spring 403 and the telescopic sleeve assembly 402.

[0029] 2) Then the transmission rod 406 pushes the limiting slide plate 408 on the connecting seat 407 to slide along the inclined slide groove, so that the two trapezoidal blocks 40 separate and stretch the second return spring 410 to form a multi-stage buffer;

[0030] 3) Finally, the extension force of the second reset spring 410 can assist the trapezoidal block 409 in resetting, shortening the system recovery time.

[0031] In summary, this wastewater treatment and recycling pressure reduction buffer stabilization device, by setting up a pressure reduction buffer mechanism 4, when water pressure pushes the flow limiting block 413, firstly, the movable plate 411 will drive the second fixed block 404 to compress the first reset spring 403 and the telescopic sleeve assembly 402. Then, the transmission rod 406 pushes the limiting slide plate 408 on the connecting seat 407 to slide along the inclined slide groove, so that the two trapezoidal blocks 40 separate and stretch the second reset spring 410, forming a multi-stage buffer. Finally, the extension force of the second reset spring 410 can assist the trapezoidal block 409 to reset, shortening the system recovery time. Thus, this mechanism can effectively resolve the situation where the pipe is easily burst when the water pressure is too high. It has strong practicality and safety, and solves the problem that the device has limited pressure reduction capacity and cannot perform multi-stage pressure reduction, which leads to the inability to stabilize pressure reduction and sudden pressure drop when encountering large water volume or water flow mixed with high temperature and pressure. In severe cases, it may even cause personal injury due to pipe wall rupture.
