Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment agent spreading device. Background Art

[0002] The discharge of industrial sewage, rainwater sewage, domestic sewage, etc. into rivers has caused serious river pollution and damaged the ecological environment of rivers. In order to solve this problem, the existing technology mainly starts from closing the pollution source and sewage treatment. Among them, sewage treatment is mainly achieved in two ways: one is physical method, such as pollutant salvage; the other is chemical method, that is, spreading sewage treatment agents into sewage.

[0003] However, the existing methods of spreading sewage treatment agents have many shortcomings. The traditional manual spreading method usually requires workers to hold a sprayer or spreader along the river and throw the agent directly into the river. This method is not only inefficient and labor-intensive, but also has extremely uneven distribution of the agent, which seriously affects the treatment effect. In addition, manual operation also has certain safety risks, especially in severe weather conditions.

[0004] In order to overcome the limitations of traditional methods, some areas have tried to use drones for spraying. Although drone spraying can improve efficiency and coverage to a certain extent, this method also has obvious disadvantages. First, the cost of drone spraying is high and requires professional operators to control it, which increases operating costs. Secondly, in a windy environment, the pesticides sprayed by drones are easy to deviate from the target area, which not only fails to achieve the expected treatment effect, but may also cause harm to coastal organisms and plants, causing ecological problems. Summary of the invention

[0005] The purpose of the present invention is to provide a sewage treatment agent spreading device to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the present invention provides a sewage treatment agent spreading device, comprising a water-driven spreading mechanism arranged at one end of the downstream of the river channel to be treated close to the upstream, the water-driven spreading mechanism being connected to a storage bin fixed on the shore via a gravity feeding pipe; The water-driven spreading mechanism includes a sealed feed pipe fixed on the river channel to be managed, a spiral feed shaft horizontally rotatably arranged inside the sealed feed pipe, and a water wheel. The bottom end of the spiral feed shaft is fixedly connected to the water wheel sealed and rotatably arranged at the bottom end of the sealed feed pipe, and a discharge port is opened at the top of the sealed feed pipe and aligned with the output end of the top of the spiral feed shaft.

[0007] Preferably, the top end of the sealed feed pipe is also horizontally rotatably connected to a spreading plate that is connected to the discharge port at the top end of the sealed feed pipe. The spreading plate is a hollow structure, and includes a bottom limit plate and a top limit plate. The bottom limit plate and the top limit plate are fixedly connected via connecting columns distributed circumferentially around the discharge port.

[0008] Preferably, the bottom end of the bottom limiting plate is fixedly connected to the top end of the flexible stirring bar, and the bottom end of the flexible stirring bar extends below the water surface of the river channel to be managed.

[0009] Preferably, a plurality of water-driven spreading mechanisms arranged linearly are fixed at one end of the downstream of the river channel to be regulated close to the upstream, and the spreading discs of the plurality of water-driven spreading mechanisms are arranged in a staggered manner in height; The straight line formed by the multiple water-driven spreading mechanisms is perpendicular to the river channel to be managed.

[0010] Preferably, the plurality of water-driven spreading mechanisms are connected to the storage bin via gravity feeding pipes, and the gravity feeding pipes are inclined downward from both sides of the river channel to be managed.

[0011] Preferably, an infrared transmitter and an infrared receiver are fixed at symmetrical positions on the inner wall of the bottom end of the storage bin, and the infrared receiver is connected to the sound and light alarm via a controller.

[0012] Preferably, a strip-shaped transparent observation window is provided on the side of the storage bin.

[0013] Therefore, the present invention adopts the above-mentioned sewage treatment agent spreading device, which has the following beneficial effects: 1. High efficiency and energy saving: (1) Water-driven design: The kinetic energy of the water flow is used to drive the water wheel, which in turn drives the spiral feed shaft and the spreading disc to rotate. No additional power source is required, which is energy-saving and environmentally friendly. (2) Self-weight feeding: The sewage treatment agent is transported from the storage bin to the bottom of the sealed feed pipe through the self-weight feeding pipe, reducing the energy consumption of mechanical transportation. 2. Uniform spreading: (1) Multi-point deployment: Multiple water-driven spreading mechanisms are fixed near the upstream end of the downstream of the river to be treated, and the spreading discs of these mechanisms are arranged in a staggered height, which reduces the blind spots of spreading and ensures the uniform distribution of the sewage treatment agent; (2) Centrifugal spreading: Through the rotation of the spiral feed shaft and the spreading disc, the sewage treatment agent is evenly spread into the river under the action of centrifugal force; 3. Improve dissolution speed: The flexible stirring bar at the bottom of the spreading plate extends below the water surface of the river channel, and plays a stirring role as the spreading plate rotates, accelerating the dissolution of the sewage treatment agent and improving the treatment effect. In addition, since the flexible stirring bar is made of polyurethane material, it can not only stir effectively, but also avoid damage due to rigid collision, thus extending the service life; 4. Automatic monitoring: The storage bin is equipped with an infrared transmitter and an infrared receiver. When the material in the storage bin is lower than the set height, the infrared receiver receives the signal and triggers the sound and light alarm through the controller to remind the staff to replenish the material in time to ensure the continuous operation of the device; 5. Compact structure and easy installation: The whole device consists of multiple modules, such as storage bin, gravity feeding pipe, sealed feeding pipe, spiral feeding shaft, water wheel, spreading plate, etc. Each part has a compact structure and is easy to install and maintain; 6. Strong adaptability: The number and position of the water-driven spreading mechanism can be adjusted according to the specific conditions of the river (such as width, flow rate, etc.), so it is suitable for rivers of different sizes. It can not only be used for spreading sewage treatment agents, but also can be applied to other types of water treatment by replacing the spreading materials; 7. High safety: (1) No power source: Since the entire device is driven by water power, there is no motor or other power source, which reduces safety hazards; (2) Anti-blocking design: The height of the material passage is not lower than the particle size of the sewage treatment agent, which reduces the possibility of blockage and ensures the normal operation of the device; In summary, the present invention realizes efficient, uniform and energy-saving sewage treatment agent spreading through hydraulic drive, multi-point layout, flexible stirring bars, automatic monitoring and other designs, improves the sewage treatment effect, and has the advantages of compact structure, easy installation and easy maintenance.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, a sewage treatment agent spreading device includes a water-driven spreading mechanism arranged at one end of the downstream of a river channel 3 to be treated close to the upstream, the water-driven spreading mechanism is connected to a storage bin 1 fixed on the shore via a gravity feeding pipe 2; the water-driven spreading mechanism includes a sealed feeding pipe 7 fixed on the river channel 3 to be treated, a spiral feeding shaft horizontally rotatably arranged inside the sealed feeding pipe 7, and a water wheel 8, the bottom end of the spiral feeding shaft is fixedly connected to the water wheel 8 sealed and rotatably arranged at the bottom end of the sealed feeding pipe 7, and a discharge port is opened at the top of the sealed feeding pipe 7 and aligned with the output end of the top of the spiral feeding shaft.

[0020] The top of the sealed feed pipe 7 is also horizontally rotatably connected to a spreading plate connected to the discharge port at the top of the sealed feed pipe 7. The spreading plate is a hollow structure, and includes a bottom limit plate 5 and a top limit plate 4. The bottom limit plate 5 and the top limit plate 4 are fixedly connected via connecting columns distributed around the discharge port. A material passing channel is left between the bottom limit plate 5 and the top limit plate 4, and the height of the material passing channel is not less than the particle size of the sewage treatment agent.

[0021] The bottom end of the bottom limit plate 5 is fixedly connected to the top end of the flexible stirring bar 6, and the bottom end of the flexible stirring bar 6 extends below the water surface of the river 3 to be treated. The flexible stirring bar 6 in this embodiment is polyurethane, which is convenient for stirring the sewage treatment agent to quickly dissolve in water and avoid precipitation of the sewage treatment agent. Moreover, due to its flexible characteristics, it can avoid impact damage to it by pollutants in the river.

[0022] A plurality of water-driven spreading mechanisms arranged linearly are fixed at one end of the downstream of the river channel to be managed close to the upstream, and the spreading discs of the plurality of water-driven spreading mechanisms are arranged at staggered heights; a straight line formed by the plurality of water-driven spreading mechanisms is perpendicular to the river channel to be managed, and the plurality of water-driven spreading mechanisms arranged in staggered heights are used to reduce dead angles.

[0023] Multiple water-driven spreading mechanisms are connected to the storage bin 1 via the gravity feeding pipe 2. The gravity feeding pipe 2 is inclined downward from both sides of the river channel to be managed, thereby realizing the gravity feeding of the water-driven spreading mechanism located in the middle.

[0024] An infrared transmitter and an infrared receiver are fixed at symmetrical positions on the inner wall at the bottom of the storage bin 1. The infrared receiver is connected to the sound and light alarm via a controller, so that when the material in the storage bin 1 is lower than the infrared transmitter, the material loses its shielding effect on the infrared transmitter, and the infrared receiver receives the signal emitted by the infrared transmitter and transmits the signal to the controller. The controller controls the sound and light alarm to sound and light alarm to remind the staff to replenish the material.

[0025] It should be noted that the above-mentioned electronic components are mature products on the market. This embodiment only needs to purchase them and connect them according to the instructions. No improvement is made to them, so their circuit connection structure and principle will not be described in detail here.

[0026] A strip-shaped transparent observation window is provided on the side of the storage bin 1, so that the material height can be observed through the transparent observation window and the material can be replenished when the material height is low.

[0027] The storage bin 1 in this embodiment is fixed to the ground via a bracket, and a discharge funnel is fixed to the bottom end of the storage bin 1, the bottom end of the discharge funnel is connected to one end of a self-gravity feeding pipe 2, and the other end of the self-gravity feeding pipe 2 is connected to the bottom end of a sealed feed pipe 7.

[0028] Working principle: The sewage treatment agent in the storage bin 1 enters the bottom end of the sealed delivery pipe 7 through the discharge funnel and the gravity feeding pipe 2, and at the same time, the water flow impacts the water wheel 8 (since the direction of the water flow is fixed, that is, the direction of the water flow is from upstream to downstream, the rotation direction of the water wheel 8 is fixed), driving the water wheel 8 to rotate, and then driving the spiral delivery shaft and the spreading plate to rotate, thereby driving the sewage treatment agent to move upward until it reaches the discharge port of the sealed delivery pipe 7, and then under the action of centrifugal force, it is spread to the inside of the river channel through the discharge port and the material transfer channel of the sealed delivery pipe 7, and because the spreading plate drives the flexible stirring bar 6 to rotate around the sealed delivery pipe 7 during rotation, the sewage treatment agent is stirred to accelerate dissolution, thereby improving the sewage treatment effect.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
