Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment facilities, and in particular relates to a sewage treatment agent spraying device. Background Art

[0002] In the field of sewage treatment, it is often necessary to add chemicals according to the different pollutant components in the sewage. For example, coagulants, flocculants, acid-base regulators, oxidants, reducing agents, and phosphorus removal agents are added to achieve the effects of removing suspended solids and organic matter, adjusting the pH value, and removing nitrogen and phosphorus. Before adding chemicals, it is necessary to fully understand the nature of the sewage and the treatment objectives in order to select the appropriate chemicals and design an appropriate dosing plan. In existing dosing treatment methods, a dosing pump is usually used to pump the proportioned chemical solution directly into the sewage pipe or pump it into the sewage tank. The flow of sewage in the pipe or the stirring device installed in the sewage tank promotes mixing between the dosing solution and the sewage.

[0003] The aforementioned dosing and mixing methods cannot ensure rapid mixing of the chemical solution / treatment agent added to the sewage, especially for relatively static sewage (non-flowing or slow-flowing). Therefore, it is necessary to develop new technologies for applying treatment solutions / treatment agents to sewage to address the aforementioned technical issues. Utility Model Content

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0024] See Figure 1 and Figure 2 The sewage treatment agent spraying device of the present invention comprises a movable support platform 21, a treatment agent tank 15 mounted at the rear of the support platform 21, and a spray assembly mounted at the front of the support platform 21. Its operating principle is as follows: the support platform 21 moves horizontally above the sewage pool. During this movement, the spray assembly sprays the treatment agent in the treatment agent tank 15 onto the sewage in the pool below. This solves the uneven and slow mixing problems of centralized application and significantly improves the efficiency of treatment agent application to the sewage.

[0025] In this embodiment, a track 13 is installed above the sewage tank, and track wheels 12 are installed on both sides of the support platform 21. The track wheels 12 roll along the track 13 on their respective sides, and a travel motor is also included to drive the track wheels 12. By controlling the forward and reverse operation of the travel motor, the support platform 21 moves forward or backward along the direction defined by the track 13.

[0026] The treatment agent tank 15 is a cylindrical tank stably mounted on a support platform 21. A filling port is located at the top of the tank 15, and a tank cap 18 is mounted on the filling port. When the treatment agent inside is depleted, the tank 15 returns to its original position for refilling. A tank drain valve 20 is located at the bottom of the tank 15. This valve is opened to drain any remaining treatment agent or cleaning wastewater.

[0027] In this embodiment, a hot air passage extending axially through the treatment agent tank 15 is provided, and a hot air blower 17 is mounted at the end of the hot air passage. The hot air passage and hot air blower 17 are provided for the following reasons: hot air blower 17 generates hot air, which passes through the hot air passage and heats the treatment agent within the tank. This heating of the treatment agent prevents freezing at low temperatures, and the increased temperature ensures the activity of the treatment agent.

[0028] In this embodiment, the treatment agent tank 15 is equipped with a liquid level indicator assembly 16. This assembly comprises a buoyancy mechanism disposed within the tank and an indicator mechanism mounted on the outer wall of the treatment agent tank 15. The indicator pointer is coaxial with the buoyancy arm of the buoyancy mechanism. The buoyancy mechanism comprises the aforementioned buoyancy arm and a pontoon. The pontoon floats on the surface of the treatment agent and rises and falls with changes in the treatment agent level. The coaxial pointer swings accordingly, and in conjunction with the arc-shaped scale of the indicator mechanism, the amount of treatment agent in the treatment agent tank 15 can be determined. When the treatment agent is depleted, refilling is necessary.

[0029] The spray assembly includes a support frame 3, the bottom of which is fixedly connected to the front of the support platform 21. Two left and right electric lift rods 4 are mounted on the support frame 3. The spray mechanism 2 is mounted at the lower end of the telescopic rods of the lift rods 4, enabling the spray mechanism 2 to be raised and lowered. In this embodiment, a protective cover 5 is provided on the outside of the support frame 3 to enclose the support frame 3 and the lift rods 4, preventing people and foreign objects from entering the area where the support frame 3 is located.

[0030] See Figure 3 and Figure 4 , we can see that:

[0031] The spraying mechanism 2 includes a main beam 2-1 fixedly connected to the lower end of the telescopic rod of the lifting electric push rod 4. A plurality of main nozzles 2-2 are mounted at the bottom of the main beam 2-1. A telescopic beam 2-4, which is driven and moved by a telescopic electric push rod 2-3, is also mounted on the side of the main beam 2-1. A plurality of movable nozzles 2-5 are mounted at the bottom of the telescopic beam 2-4. By controlling the telescopic rods 2-3 to extend and retract, the telescopic beams 2-4 can be moved outward or inward, correspondingly widening or narrowing the spraying range of the spraying mechanism 2. The spraying range can be set to coincide with the width of the sewage pool below. That is, by controlling the telescopic rods 2-3 to extend and retract, the outer end of the telescopic beam 2-4 is moved close to the pool wall.

[0032] In this embodiment, a guide sleeve is installed on the side of the main beam 2-1, and the telescopic beam 2-4 is located in the guide sleeve. In this way, when the telescopic beam 2-4 moves horizontally, stability can be guaranteed. The combination of the guide sleeve and the telescopic beam 2-4 can also ensure the overall structural strength of the spraying mechanism 2.

[0033] In this embodiment, guide assemblies 22 are installed on both sides of the support frame 3. The guide assemblies 22 include a guide sleeve and a guide rod located in the guide sleeve. The guide sleeve is fixed on the support frame 3, and the lower end of the guide rod is fixedly connected to the main beam 2-1. By setting the guide assembly 22, the stability of the spraying mechanism 2 during lifting and moving can be improved.

[0034] In this embodiment, a shielding cover 1 is installed on the main beam 2-1 of the spraying mechanism 2, and each main nozzle 2-1 is located inside the shielding cover 1. The shielding cover 1 can alleviate the problem of the treatment agent splashing to both sides during spraying to a certain extent.

[0035] It also includes a delivery component for delivering the treatment agent in the treatment agent tank 15 to each main nozzle 2-2 and the mobile nozzle 2-5. Figure 1 and Figure 2 , it can be seen that the delivery assembly includes a liquid separation valve 8 and a delivery pump 9 installed and fixed on the support platform 21. The liquid separation valve 8 has an input interface and multiple output interfaces. The input interface is connected to the outlet of the delivery pump 9 through a pipeline, and each output interface is connected to each main nozzle 2-2 and the mobile nozzle 2-5 through a pipeline. The treatment agent delivered by the delivery pump 9 is divided into multiple paths at the liquid separation valve 8 and delivered to each main nozzle 2-2 and the mobile nozzle 2-5 at the same time. The delivery pump 9 can be selected as a metering pump with a flow metering function. During the spraying process of the treatment agent, it is determined whether the spraying of the treatment agent on the sewage in the current sewage pool has been completed by measuring the spraying amount.

[0036] In this embodiment, a coarse filter box 14 and a fine filter 11 are further mounted on the support platform 21. The outlet of the treatment agent tank 15 is docked with the inlet of the coarse filter box 14. The outlet of the coarse filter box 14 is connected to the inlet of the fine filter 11 via a pipeline, and the outlet of the fine filter 11 is connected to the inlet of the delivery pump 9 via a pipeline. The coarse filter box 14 and the fine filter 11 are provided to filter the treatment agent, thereby improving the cleanliness of the treatment agent by filtering out the particulate matter contained therein, and effectively avoiding the problem of clogging of subsequent pipelines and nozzles.

[0037] The coarse filter box 14 is mainly used to filter and retain large particles of impurities. It is equipped with a multi-stage filter screen. A filter drain valve 19 is provided at the bottom of the coarse filter box 14. The filter drain valve 19 is opened regularly to discharge the impurities inside. The fine filter 11 is used to filter and retain small particles of impurities and can be selected as a pipeline filter.

[0038] A control box 7 and a cable reel 10 are mounted on the support platform 21, located on either side of the center-front portion of the support platform 21. The cables on the cable reel 10 are connected to a fixed power supply near the sewage tank to ensure power supply to the sewage treatment agent spraying device. The control box 7 controls the movement of the spraying device, the height adjustment and width change of the spray mechanism 2, and the start and stop of the treatment agent spraying.

[0039] In this embodiment, a carrying platform 6 is also mounted on the support platform 21. The carrying platform 6 is located between the treatment agent tank 15 and the support frame 3. The carrying platform 6 is used to carry people or objects. For example, when personnel need to reach the upper part of the sewage tank to observe the working conditions, they can stand on the carrying platform 6. Furthermore, as shown in the figure, the conveying components and hot air blower 17 on the support platform 21 are located below the carrying platform 6, providing a certain degree of protection.

[0040] How to run:

[0041] Add treatment agent into the treatment agent tank 15; control the spraying mechanism 2 to change its shape through the control box 7, specifically first adjust the overall width of the spraying mechanism 2 so that the spraying range of each nozzle covers the pool surface of the sewage pool below, and then lower the height of the spraying mechanism 2 so that each nozzle is sufficiently close to the surface of the sewage in the pool (the nozzle and the shielding cover 1 should avoid contact with the sewage), so as to avoid splashing to both sides as much as possible during the spraying of the treatment agent; start the delivery pump 9 through the control box 7; control the spraying device through the control box 7 to move along the direction specified by the track 13, spraying the treatment agent while moving, and after completing the spraying of a specific amount of treatment agent, stop the delivery pump 9 and return to the initial position.
