Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, specifically to a sewage treatment agent dispensing device for sewage treatment. Background Technology

[0002] In wastewater treatment processes, the precise addition of powdered wastewater treatment agents to the treatment tank is a crucial step in improving water purification efficiency. The uniformity and accuracy of the dosage directly affect the mixing and reaction efficiency between the agent and the wastewater. Uneven dosing can lead to excessively high agent concentrations in some areas, causing clumping, or excessively low concentrations that fail to achieve the desired treatment effect. This not only wastes the agent but also reduces the overall operating efficiency of the wastewater treatment system and increases subsequent treatment costs. Currently, powder feeding devices for wastewater treatment tanks in the industry are mainly divided into two categories: one is a manual pouring method, where operators directly sprinkle powder into the wastewater treatment tank. This method relies entirely on manual experience to control the dosage, which is not only labor-intensive and inefficient, but also makes it difficult to achieve uniform spreading along the width of the wastewater treatment tank, especially for tanks larger than 3 meters. In wastewater treatment tanks with a width of several meters, the amount of powder accumulated on the side closer to the operator is much higher than on the other side, creating a significant concentration difference that severely affects the reaction effect of the reagents. Another type uses mechanical feeding devices, such as screw conveyors or vibrating feeding structures. Although these devices can replace manual feeding for automatic feeding, they still have significant drawbacks: Firstly, the discharge ports of screw conveyors or vibrating feeding structures are usually fixed single points or a few points, which cannot be adapted to the width of the wastewater treatment tank for large-area uniform distribution. Additional feeding mechanisms are required to achieve wide coverage, resulting in complex device structures, large footprints, and the operation of additional mechanisms is easily restricted by the space above the wastewater tank, leading to high maintenance costs. Secondly, the quantitative control accuracy of existing mechanical devices is low. Most of them indirectly control the amount of feed by adjusting the feeding speed or the opening time, which cannot form a stable quantitative cavity for accurate measurement. When the moisture content of the powder changes or the particle size is uneven, blockage or leakage is prone to occur, further affecting the stability of the feeding. Therefore, in view of the problems of poor uniformity and low quantitative accuracy of existing sewage treatment agent powder dispensing devices, there is an urgent need to develop a spreading device that can adapt to the width of the sewage treatment tank, achieve accurate quantitative metering, and has a simple structure, so as to improve the agent dispensing effect and the operational stability of the sewage treatment system. Utility Model Content

[0003] In order to solve the technical problems existing in the prior art, this application provides a wastewater treatment agent dispensing device for wastewater treatment.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a wastewater treatment agent dispensing device for wastewater treatment, comprising: a powder silo for accommodating the powder to be dispensed, the powder silo being installed in the upper part of the wastewater treatment tank, the length direction of the powder silo being adapted to the width direction of the wastewater treatment tank; a dispensing mechanism being provided at the bottom of the powder silo, the dispensing mechanism including a feeding plate hinged to the bottom of the powder silo and a driving rod for driving the feeding plate to rotate, one end of the driving rod being rotatably disposed in the powder silo, and the other end of the driving rod being rotatably disposed on the feeding plate; a baffle plate being provided on the powder silo, the baffle plate being slidably disposed in the powder silo, and a cavity for quantitatively measuring the powder to be dispensed being formed between the baffle plate and the feeding plate.

[0005] In some embodiments of this utility model, the powder silo is provided with a drive mechanism for driving the reciprocating motion of the baffle plate. The drive mechanism includes a drive rod, a sector gear, a driven wheel, and an eccentric block. The drive rod is disposed on the powder silo, and the direction of the drive rod is consistent with the sliding direction of the baffle plate. The sector gear is rotatably disposed on the powder silo. The drive rod is provided with a rack that meshes with the sector gear. The driven wheel is disposed on the powder silo. The eccentric block is disposed on the outer edge of the driven wheel. The sector gear has a strip groove, and the eccentric block is slidably disposed in the strip groove. The powder silo is provided with a power component for driving the driven wheel to rotate, and the power component is connected to the driven wheel.

[0006] In some embodiments of this utility model, the aforementioned power component includes a motor, a drive pulley, and a belt. The motor is mounted on the powder silo, the drive pulley is mounted on the output end of the motor, and the belt connects the drive pulley and the driven pulley.

[0007] In some embodiments of this utility model, the end of the material blocking plate located inside the powder hopper is provided with a chamfered structure.

[0008] In some embodiments of this utility model, the side of the powder hopper that abuts against the material blocking plate is provided with a groove with a chamfered structure, and the chamfered structure can extend into the groove.

[0009] In some embodiments of this utility model, the powder silo includes a storage section, a collection section, and a metering section connected sequentially from top to bottom, and the storage section, collection section, and metering section are integrally formed.

[0010] In some embodiments of this utility model, the inner surface of the powder hopper is covered with a guide layer for reducing the coefficient of friction between the powder to be dispensed and the hopper wall. Beneficial effects

[0011] 1. The powder hopper length is adapted to the width of the wastewater treatment tank. Combined with the overall feeding design of the bottom dispensing mechanism, the powder can be evenly spread along the width of the wastewater treatment tank, avoiding the problems of localized agent accumulation and insufficient agent in some areas caused by traditional single-point or small-point dispensing. For large wastewater treatment tanks with a width of 3-8 meters, there is no need to add additional moving guide rails or rotating material distribution components, which can achieve uniform contact between wastewater and agents throughout the tank, reducing problems such as flocculation and dead zones caused by uneven agent distribution, and improving the overall wastewater treatment efficiency.

[0012] 2. The dispensing mechanism drives the feeding plate to flip and discharge the powder through a drive rod. The powder slides smoothly down the surface of the feeding plate. Compared with the pulse discharge of vibrating feeding, it can avoid local concentration fluctuations caused by the powder splashing or concentrated falling due to vibration, and further ensure the uniformity of the longitudinal distribution of the agent in the wastewater, providing a stable agent environment for subsequent reactions.

[0022] Please refer to Figures 1-4 This embodiment provides a wastewater treatment agent dispensing device for wastewater treatment, which includes: a powder silo 1 for containing powder to be dispensed, the powder silo 1 being installed in the upper part of the wastewater treatment tank, the length of the powder silo 1 being adapted to the width of the wastewater treatment tank; a dispensing mechanism is provided at the bottom of the powder silo 1, the dispensing mechanism including a feeding plate 2 hinged to the bottom of the powder silo 1 and a driving rod 3 for driving the feeding plate 2 to rotate, one end of the driving rod 3 being rotatably disposed on the powder silo 1, and the other end of the driving rod 3 being rotatably disposed on the feeding plate 2; a blocking plate 4 is provided on the powder silo 1, the blocking plate 4 being slidably disposed in the powder silo 1, and a cavity 5 for quantitatively measuring the powder to be dispensed is formed between the blocking plate 4 and the feeding plate 2.

[0023] First, the powdered wastewater treatment agent to be added is loaded into the powder silo 1. The powder silo 1, based on a structure installed in the upper part of the wastewater treatment tank, provides a stable high-level storage space for subsequent additions. By sliding the baffle plate 4 inside the powder silo 1, the volume of the cavity 5 between the baffle plate 4 and the feeding plate 2 is adjusted. After setting the single-use dosage according to the wastewater treatment requirements, the baffle plate 4 is fixed in position, and the powder in the powder silo 1 naturally falls into the quantitative cavity 5, completing the accurate measurement of the single-use dosage. The drive rod 3 then begins to move. One end rotates around a fixed point on the powder silo 1, while the other end drives the feeding plate 2, which is hinged to the bottom of the powder silo 1, to flip downwards. As the feeding plate 2 flips, the powder in the metering cavity 5 slides down the surface of the feeding plate 2. Because the length of the powder silo 1 is adapted to the width of the sewage treatment tank, the powder can be evenly spread into the sewage along the width of the tank, completing one feeding cycle. After feeding, the drive rod 3 moves in the opposite direction, driving the feeding plate 2 to reset. The blocking plate 4 can slide again to adjust the volume of the cavity 5, and enter the next feeding process.

[0024] Specifically, the aforementioned powder silo 1 serves as a storage carrier for powder. A high-mounted feeding mechanism allows the powder to fall naturally to the bottom using gravity, eliminating the need for additional feeding power. The matching length and trough width ensure consistent coverage during powder feeding, preventing missed areas. The feeding plate 2 is connected to the bottom of the powder silo 1 via a hinge shaft and can freely rotate around the hinge shaft. The drive rod 3 has a double-rotating connection structure, with one end connected to the powder silo 1 and the other end connected to the feeding plate 2. The extension and retraction of the drive rod 3 converts power into the rotation of the feeding plate 2. When the drive rod 3 extends, it causes the feeding plate 2 to flip downwards, opening the feeding channel; when the drive rod 3 retracts, it causes the feeding plate 2 to flip upwards, closing the feeding channel and resetting.

[0025] In this embodiment, the aforementioned blocking plate 4 slides laterally through the inner wall groove of the powder hopper 1 (not shown in the figure). When sliding, it can change the relative distance between the plate and the powder hopper 1, thereby changing the volume of the enclosed space of the cavity 5. When the blocking plate 4 slides to the target position, it can be fixed by bolts, clips, or other structures. At this time, the powder in the powder hopper 1 can only fill the quantitative cavity 5, and the excess powder is blocked by the blocking plate 4, thus achieving accurate measurement of the single dispensing amount.

[0026] Please refer to Figure 1 and Figure 2 In some embodiments of this example, the powder silo 1 is provided with a drive mechanism for driving the reciprocating motion of the baffle plate 4. The drive mechanism includes a drive rod 3, a sector gear 7, a driven wheel 8, and an eccentric block 9. The drive rod 3 is disposed on the powder silo 1, and the direction of the drive rod 3 is consistent with the sliding direction of the baffle plate 4. The sector gear 7 is rotatably disposed on the powder silo 1. The drive rod 3 is provided with a rack 10 that meshes with the sector gear 7. The driven wheel 8 is disposed on the powder silo 1. The eccentric block 9 is disposed on the outer edge of the driven wheel 8. The sector gear 7 has a strip groove 11. The eccentric block 9 is slidably disposed in the strip groove 11. The powder silo 1 is provided with a power component for driving the driven wheel 8 to rotate. The power component is connected to the driven wheel 8.

[0027] It should be noted that the aforementioned material blocking plate 4 drive mechanism converts the rotational motion of the power component into the reciprocating linear motion of the material blocking plate 4 through mechanical transmission, thereby achieving precise sliding adjustment of the material blocking plate 4 within the powder hopper 1.

[0028] Specifically, the aforementioned power component is directly connected to the driven wheel 8. When the device needs to adjust the position of the baffle plate 4, the power component starts and outputs rotational power, driving the driven wheel 8 to rotate at a constant speed around its fixed axis. The eccentric block 9, fixed to the outer edge of the driven wheel 8, rotates synchronously with the driven wheel 8, providing the basic power for subsequent motion conversion. The eccentric block 9 is fixed to the outer edge of the driven wheel 8, and its installation position does not coincide with the rotation axis of the driven wheel 8. When the driven wheel 8 rotates, the eccentric block 9 will perform circular motion with the axis of the driven wheel 8 as the center and the radius and eccentricity of the driven wheel 8 as the trajectory, forming an eccentric rotation trajectory.

[0029] The slot 11 on the aforementioned sector gear 7 is a long, through slot, with its length aligned with the radial direction of the sector gear 7. The eccentric block 9 is embedded within the slot 11 and can slide freely along the slot wall. When the eccentric block 9 makes a circular motion, its position within the slot 11 will change relative to the trajectory. When the driven wheel 8 rotates half a revolution, the eccentric block 9 pushes one side of the slot wall of the slot 11, causing the sector gear 7 to swing in one direction around its fixed axis. When the driven wheel 8 rotates the other half revolution, the eccentric block 9 pulls the other side of the slot wall of the slot 11, causing the sector gear 7 to swing in the opposite direction. The continuous rotational motion of the driven wheel 8 is converted into the reciprocating oscillating motion of the sector gear 7.

[0030] The aforementioned drive rod 3 is mounted on the powder hopper 1, and its orientation is completely consistent with the sliding direction of the baffle plate 4, ensuring that the movement of the drive rod 3 can be directly transmitted to the baffle plate 4. The drive rod 3 is machined with a rack 10 that fully meshes with the sector gear 7, and the length of the rack 10 is adapted to the swing stroke of the sector gear 7. When the sector gear 7 swings back and forth, the meshing relationship between its teeth and the rack 10 generates a driving force along the length of the rack 10. When the sector gear 7 swings clockwise, the gear teeth push the rack 10 to drive the drive rod 3 to move in a straight line along the sliding direction of the baffle plate 4. When the sector gear 7 swings counterclockwise, the gear teeth pull the rack 10, causing the drive rod 3 to move in a straight line in the backward direction along the sliding direction of the material blocking plate 4.

[0031] Please refer to Figures 1-4 In some embodiments of this example, the power component includes a motor, a drive pulley 13 and a belt 14. The motor is mounted on the powder silo 1, the drive pulley 13 is mounted on the output end of the motor, and the belt 14 connects the drive pulley 13 and the driven pulley 8.

[0032] In this embodiment, the motor is fixedly installed on the outer wall of the powder silo 1 or on a preset bracket. Its output shaft is fixedly connected to the drive wheel 13 by a key, and the motor output shaft and the drive wheel 13 rotate synchronously. When it is necessary to adjust the position of the material blocking plate 4, the motor starts after receiving a control signal, and the output shaft drives the drive wheel 13 to rotate at a set speed.

[0033] The aforementioned belt 14 is fitted within the grooves of the driving wheel 13 and the driven wheel 8, and power transmission is achieved through the friction between the belt 14 and the grooves. When the driving wheel 13 rotates, the belt 14 moves with the driving wheel 13, thereby driving the driven wheel 8 to rotate around its own fixed axis in the same direction and with the same transmission ratio. If the driving wheel 13 rotates clockwise, the belt 14 drives the driven wheel 8 to rotate clockwise synchronously, and the rotational speed of the driven wheel 8 can be precisely controlled by the diameter ratio of the driving wheel 13 and the driven wheel 8 to meet the speed adjustment requirements of different resistance plates 4. The eccentric block 9 on the outer edge of the driven wheel 8 is connected to the driven wheel 8 by welding, and it moves in a circular motion with the rotation of the driven wheel 8. Its motion trajectory is still a circle with the axis of the driven wheel 8 as the center and the radius of the driven wheel 8 and the eccentricity as the radius, providing a stable power foundation for subsequent motion conversion links.

[0034] Preferably, the motor is a servo motor 12 or a stepper motor, which has controllable speed and sensitive start and stop.

[0035] Please refer to Figure 4 In some embodiments of this example, the material blocking plate 4 is provided with a chamfered structure 15 at one end located inside the powder hopper 1.

[0036] In this embodiment, the chamfered structure 15 is used to form a cutting edge on the edge of the material blocking plate 4, which reduces the cutting friction between the material blocking plate 4 and the powder when the material blocking plate 4 is closed.

[0037] In some embodiments of this example, the side of the powder hopper 1 that abuts against the material blocking plate 4 is provided with a groove 16 that is connected to the chamfered structure 15, and the chamfered structure 15 can extend into the groove 16.

[0038] In this embodiment, when the aforementioned baffle plate 4 slides on the inner wall of the powder hopper 1, a small gap needs to be reserved to avoid jamming. If the baffle plate 4 relies solely on its right-angled end to adhere to the inner wall, the gap can easily become a channel for powder leakage. Especially when there is a certain pressure in the powder hopper 1, fine particles of powder can easily seep out from the gap, causing powder to leak out of the cavity 5. This not only wastes the reagent but may also cause the leaked powder to accumulate in the chute, affecting the sliding accuracy of the baffle plate 4. The fitting and matching of the groove 16 and the chamfered structure 15 allows the chamfered structure 15 to fully extend into the groove. The chamfered structure is embedded in the groove 16, transforming the original planar gap into a mating surface within the groove, significantly reducing the gap space for powder leakage.

[0039] Please refer to Figures 1-4 In some embodiments of this example, the powder hopper 1 includes a storage section 101, a collection section 102, and a metering section 103 connected sequentially from top to bottom, and the storage section 101, the collection section 102, and the metering section 103 are integrally formed.

[0040] In this embodiment, the above-mentioned storage section 101 has a high-level, large-capacity storage capacity to ensure continuous material supply. It is located at the top of the powder silo 1 and is usually a cuboid structure with a spacious interior. The volume is based on the daily chemical consumption of the sewage treatment system. The top is equipped with an openable feed inlet for replenishing powder, and the inner wall is smooth.

[0041] The aforementioned collecting section 102 is conical, used to collect powder and eliminate dead angles in flow. It is connected to the lower part of the storage section 101 and has a conical structure that is wider at the top and narrower at the bottom. The inner wall is a smooth slope, and the bottom is seamlessly connected to the inlet of the metering section 103. The metering unit 103 is located at the bottom of the powder silo 1 and is directly connected to the installation structure in the upper part of the sewage treatment tank. It is equipped with a material blocking plate 4 and a feeding plate 2 inside. The space between the material blocking plate 4 and the feeding plate 2 is the metering cavity 5. The inner wall of the metering unit 103 has a high fitting accuracy with the material blocking plate 4 and the feeding plate 2, ensuring the sealing of the cavity 5.

[0042] The one-piece molding design makes the three parts a complete sealed structure without any splicing gaps. The powder can only flow along the preset channels of the storage section 101, the collection section 102 and the metering section 103, which completely solves the leakage problem. At the same time, the sealed structure can prevent external dust and sewage from entering the powder silo 1, avoid the powder from getting damp and contaminated, and ensure the performance of the agent.

[0043] Please refer to Figures 1-4 In some embodiments of this example, the inner surface of the powder hopper 1 is covered with a guide layer for reducing the coefficient of friction between the powder to be dispensed and the hopper wall.

[0044] In this embodiment, the inner surface of the powder silo 1 includes the inner wall of the storage section 101, the inclined surface of the collection section 102, and the inner wall of the metering section 103. A guide layer is provided covering the entire flow path of the powder. The guide layer is typically made of a low-friction coefficient material, and its surface is polished to ensure a smooth and flat surface. Its core function is to reduce the frictional resistance between the powder and the silo wall, thereby solving the problems of powder adhesion, accumulation, and bridging, ensuring smooth powder flow throughout the process, and further optimizing the quantitative metering and operational stability of the device. Preferably, the aforementioned flow guiding layer is selected from any one of the following: polytetrafluoroethylene coating, ultra-high molecular weight polyethylene sheet, ceramic coating, etc., and the coefficient of friction can be as low as 0.05-0.1, which is much lower than the coefficient of friction of the powder silo 1 substrate such as stainless steel (0.3-0.5).

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
