Description

Technical Field

[0001] This utility model belongs to the technical field of flow control devices, and in particular relates to a wastewater flow control device for sewage treatment. Background Technology

[0002] A flow control device is a device used to manage and regulate the flow rate of fluids (such as liquids or gases). In wastewater treatment, by monitoring the wastewater flow rate and dynamically adjusting it according to actual needs, it is possible to ensure that the operating load of the wastewater treatment equipment is within a reasonable range, avoiding a decrease in treatment efficiency due to excessive or insufficient flow, and ensuring that the wastewater treatment process proceeds efficiently and stably.

[0003] Currently, in wastewater treatment processes, flow control devices are often installed at appropriate locations according to their usage requirements, such as at the inlet. These devices monitor the influent flow rate to stabilize the subsequent process load. However, the wastewater flowing at the inlet often contains impurities such as gravel, dead branches, and dead leaves. Therefore, corresponding filter components are installed to intercept these impurities and prevent them from affecting the flow control device. However, while the filter components intercept impurities, they can also cause impurities to remain on their surface. If not cleaned in time, these impurities can easily become clogged, thus affecting the use of the flow control device. Therefore, this utility model proposes a wastewater flow control device for wastewater treatment. Utility Model Content

[0004] This utility model provides a wastewater flow control device for sewage treatment. A scraping cleaning mechanism drives a scraper to scrape off attached impurities along the top inclined end of an inclined filter plate, preventing clogging and ensuring effective wastewater flow. This avoids interference with the operation of subsequent wastewater flow control devices. An adjustment mechanism allows for adjustment of the distance between the scraper and the inclined filter plate according to usage requirements. During cleaning, the scraper contacts the inclined filter plate for easy scraping, while during reset, the scraper moves away from the inclined filter plate to prevent impurities from accumulating on top and affecting subsequent cleaning. The flow control mechanism regulates and controls the wastewater flow, ensuring stable load on subsequent sewage treatment processes and preventing reduced treatment efficiency due to excessive or insufficient flow. This ensures efficient and stable sewage treatment, thus solving the problems in the prior art.

[0013] Furthermore, the adjustment mechanism includes a pair of inclined straight frames, with a connecting inclined plate fixedly connected between the opposite sides of the pair of inclined straight frames. One side of the connecting inclined plate is fixedly connected to one end of the movable inclined rod. An electric telescopic rod is fixedly connected to the inner wall of each pair of inclined straight frames, and a through hole is drilled at the top inclined end of the inclined straight frame. The output end of the electric telescopic rod passes through the through hole and extends to its outer side, and the outer wall of the output end of the electric telescopic rod is in close contact with the inner wall of the through hole. An L-shaped plate is fixedly connected between the output ends of the pair of electric telescopic rods, and the bottom end of the L-shaped plate is fixedly connected to the top inclined end of the scraper.

[0014] Furthermore, a water guide pipe is fixedly connected between the bottom end of the side frame and the other side of the L-shaped tube, and a filter screen is fixedly connected to the inner wall of the water guide pipe.

[0015] Furthermore, the flow control mechanism includes a sleeve frame fixedly connected to the top of the L-shaped tube, and a second slide cylinder is fixedly connected between the top end of the sleeve frame and the top of the L-shaped tube. An L-shaped block is fixedly connected to the output end of the second slide cylinder, and a sealing baffle is fixedly connected to the bottom end of the L-shaped block.

[0018] The present invention has the following advantages over the prior art:

[0019] 1. This technical solution uses a scraping cleaning mechanism to drive a pair of first sliding cylinders to scrape off the attached impurities along the top inclined end of the inclined filter plate. This prevents clogging of the inclined filter plate, ensures the flow effect of wastewater, and avoids interference with the operation of the subsequent wastewater flow control device. At the same time, it drives a pair of impact hammers to contact and collide with the L-shaped tube, shaking off the residual impurities attached to the surface of the scraper during the cleaning process, so as to facilitate subsequent cleaning.

[0020] 2. This technical solution uses an adjustment mechanism to drive the electric telescopic rod to bring the scraper into contact with the inclined filter plate during cleaning, so as to facilitate scraping and cleaning. After cleaning, when resetting, the scraper moves away from the inclined filter plate to avoid impurities accumulating on the top during the upward resetting process, which would affect subsequent cleaning.

[0021] 3. This technical solution, through the flow control mechanism, can drive the sealing baffle and buffer plate to move up and down along the loop block via the second slide cylinder, thereby adjusting and controlling the wastewater flow rate, ensuring the stability of the load of the subsequent wastewater treatment process, and avoiding the decline in treatment effect due to excessive or insufficient flow, thus ensuring that the wastewater treatment process is efficient and stable.

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0035] Please see Figures 1-6 As shown, the wastewater flow control device for sewage treatment according to this utility model includes:

[0036] L-shaped tube 1, with connecting buckets 2 fixedly connected to both ends of L-shaped tube 1, inclined filter plate 3 fixedly connected to the inner wall of L-shaped tube 1, side frame 5 fixedly connected to one side of L-shaped tube 1, and a guide hole 4 is cut between side frame 5 and L-shaped tube 1, and a detachable cover plate 6 is connected to the top of side frame 5 by cross screws.

[0037] The scraping cleaning mechanism 7 is located on the top of the inclined filter plate 3 and is used to scrape off the impurities attached to the surface of the inclined filter plate 3.

[0038] Adjustment mechanism 8 is located on the top of the inclined filter plate 3 and is used for scraping adjustment;

[0039] A flow control mechanism 11 is installed on the L-shaped pipe 1 and is used for regulating and controlling the flow rate of wastewater.

[0040] The scraping cleaning mechanism 7 includes a pair of inclined connecting plates 701. Each of the two inclined connecting plates 701 is fixedly connected to a first sliding cylinder 702 on its opposite side. A connecting block 703 is fixedly connected between the output ends of the pair of first sliding cylinders 702. A movable inclined rod 704 is fixedly connected to the side of the connecting block 703 near the L-shaped tube 1. A round hole is drilled on one side of the L-shaped tube 1. One end of the movable inclined rod 704 passes through the round hole and extends into the interior of the L-shaped tube 1. The outer wall of the movable inclined rod 704 is in close contact with the inner wall of the round hole. A scraper 705 is provided on one side of the movable inclined rod 704. The bottom end of the scraper 705 is in close contact with the top inclined end of the inclined filter plate 3.

[0041] In the specific implementation process, the connecting bucket 2 at the top of the L-shaped pipe 1 is connected to the pipe at the inlet, so that the wastewater flows downward through the connecting bucket 2 into the L-shaped pipe 1, and then passes through the inclined filter plate 3 to filter and intercept the impurities, allowing the wastewater to continue to flow downward. At the same time, during the filtration and interception process, a pair of first sliding rod cylinders 702 drive the connecting block 703 to move towards the L-shaped pipe 1, which drives the movable inclined rod 704 to move synchronously. This causes the movable inclined rod 704 to drive the scraper 705 to move downward along the top inclined end of the inclined filter plate 3, scraping off the attached impurities, which fall into the side frame 5 through the guide port 4. This prevents the inclined filter plate 3 from being blocked, ensuring the flow effect of the wastewater and avoiding interference with the operation of the subsequent wastewater flow control device. In addition, screw holes are drilled on the side frame 5 and the detachable cover plate 6, and they are connected and fixed with cross screws. They can be disassembled later to facilitate the cleaning of impurities inside the side frame 5.

[0042] Among them, a pair of impact hammer rods 706 are fixedly connected to the side of the connecting block 703 near the L-shaped tube 1, and the movable inclined rod 704 is located between the pair of impact hammer rods 706.

[0043] When the connecting block 703 moves downward, it drives a pair of impact hammer rods 706 to move downward synchronously until the scraper 705 moves into the guide port 4. At this time, the pair of impact hammer rods 706 move to contact and collide with one side of the L-shaped tube 1, generating vibration. The vibration shakes off the residual impurities attached to the surface of the scraper 705 during the cleaning process, so as to facilitate subsequent cleaning.

[0044] The adjustment mechanism 8 includes a pair of inclined straight frames 801. A connecting inclined plate 804 is fixedly connected between the opposite sides of the pair of inclined straight frames 801. One side of the connecting inclined plate 804 is fixedly connected to one end of the movable inclined rod 704. An electric telescopic rod 802 is fixedly connected to the inner wall of each pair of inclined straight frames 801. A through hole is drilled at the top inclined end of the inclined straight frame 801. The output end of the electric telescopic rod 802 passes through the through hole and extends to its outer side. The outer wall of the output end of the electric telescopic rod 802 is in close contact with the inner wall of the through hole. An L-shaped plate 803 is fixedly connected between the output ends of the pair of electric telescopic rods 802. The bottom end of the L-shaped plate 803 is fixedly connected to the top inclined end of the scraper 705.

[0045] The electric telescopic rod 802 drives the L-shaped plate 803 downward, which in turn drives the scraper 705 downward until it comes into contact with the inclined filter plate 3. This facilitates the scraper 705 to contact the inclined filter plate 3 during cleaning, making it easier to scrape and clean. After cleaning, when resetting upward, the electric telescopic rod 802 drives the L-shaped plate 803 upward, which moves the scraper 705 away from the inclined filter plate 3, preventing impurities from accumulating on top during the upward resetting process and affecting subsequent cleaning.

[0046] Among them, a water guide pipe 9 is fixedly connected between the bottom end of the side frame 5 and the other side of the L-shaped pipe 1, and a filter screen plate 10 is fixedly connected to the inner wall of the water guide pipe 9.

[0047] By setting up the filter screen 10 and the wide water guide pipe 9, some of the wastewater flowing into the side frame 5 can be easily returned to the L-shaped pipe 1 through the filter screen 10 and the wide water guide pipe 9. Specific Implementation Example 2:

[0049] Please see Figure 1 and Figure 6 As shown, in a preferred embodiment, the flow control mechanism 11 includes a sleeve frame 1101 fixedly connected to the top of the L-shaped tube 1, and a second slide cylinder 1102 fixedly connected between the top end of the sleeve frame 1101 and the top of the L-shaped tube 1. An L-shaped block 1103 is fixedly connected to the output end of the second slide cylinder 1102, and a sealing baffle 1105 is fixedly connected to the bottom end of the L-shaped block 1103. A U-shaped block 1104 is fixedly connected inside the L-shaped tube 1, and a rectangular opening is drilled between the U-shaped block 1104 and the top of the L-shaped tube 1. The bottom end of the sealing baffle 1105 passes through the rectangular opening and extends into the U-shaped block 1104. The outer wall of the sealing baffle 1105 is in close contact with the rectangular opening and the inner wall of the U-shaped block 1104, respectively.

[0050] In the specific implementation process, the second sliding cylinder 1102 drives the L-shaped block 1103 to move up and down, which in turn drives the sealing baffle 1105 to move up and down along the loop block 1104. The wastewater flow rate is adjusted and controlled according to the gap between the sealing baffle 1105 and the loop block 1104, so as to ensure the stability of the load of the subsequent sewage treatment process and avoid the decrease in treatment effect due to excessive or insufficient flow, so as to ensure that the sewage treatment process is efficient and stable.

[0051] Among them, a buffer plate 1106 is fixedly connected to the side of the sealing baffle 1105 away from the second slide cylinder 1102, and the outer wall of the buffer plate 1106 is in close contact with the rectangular opening and the inner wall of the U-shaped block 1104 respectively.

[0052] By using a buffer sheet 1106 made of foam plastic material and setting a wear-resistant layer on its surface, it can move synchronously with the sealing baffle 1105 to regulate and control the wastewater flow rate. At the same time, it buffers the impact of the wastewater flow and reduces its impact, thereby avoiding damage to the sealing baffle 1105.

[0053] Among them, the outer wall of the frame 1101 is rotatably connected to a pair of sealing frame doors 12 by hinges, and the pair of sealing frame doors 12 are in close contact.

[0054] The sealing frame door 12 can be used to seal and protect the inside of the sleeve frame 1101. At the same time, when it is necessary to maintain the internal components of the sleeve frame 1101, the sealing frame door 12 can be opened to facilitate maintenance by the staff.

[0055] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0056] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0057] The working principle of this utility model is as follows:

[0058] In use, the connecting bucket 2 at the top of the L-shaped tube 1 is connected to the pipe at the inlet, allowing wastewater to flow downwards through the connecting bucket 2 into the L-shaped tube 1. The wastewater then passes through the inclined filter plate 3 to filter and intercept impurities, allowing it to continue flowing downwards. Simultaneously, during the filtration process, the electric telescopic rod 802 drives the L-shaped plate 803 downwards, causing the scraper 705 to move downwards until it contacts the inclined filter plate 3. Then, a pair of first sliding cylinders 702 drive the connecting block 703 towards the L-shaped tube 1, causing the movable inclined rod 704 to move synchronously. This causes the movable inclined rod 704, through the connecting inclined plate 804 and the L-shaped plate 803, to drive the scraper 705 downwards along the top inclined end of the inclined filter plate 3, scraping off the attached impurities, which then fall through the guide port 4. The wastewater is inserted into the side frame 5, which prevents clogging of the inclined filter plate 3 and ensures the flow effect of the wastewater. After cleaning, the electric telescopic rod 802 drives the L-shaped plate 803 to move upward, causing the scraper 705 to move away from the inclined filter plate 3. Then, the first sliding cylinder 702 drives the connecting block 703 to reset upward. Next, the second sliding cylinder 1102 drives the L-shaped block 1103 to move up and down, causing the sealing baffle 1105 and the buffer plate 1106 to move up and down along the U-shaped block 1104. The wastewater flow rate is adjusted and controlled according to the gap between the sealing baffle 1105 and the U-shaped block 1104 to ensure the stability of the load of the subsequent sewage treatment process and avoid the decrease in treatment effect due to excessive or insufficient flow, so as to ensure that the sewage treatment process is efficient and stable.
