Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment agent dosing device. Background Technology
[0002] In the early stages of the wastewater treatment industry, the dosing method mostly relied on manual application of wastewater treatment agents, such as flocculants and disinfectants, into the wastewater tank. This often resulted in waste or insufficient dosing of agents, affecting the treatment effect. Moreover, the mixing of agents and wastewater depended entirely on the natural flow of wastewater, which was inefficient. Only the local wastewater near the dosing point could come into contact with the agents, making it difficult to achieve uniform mixing. This resulted in large fluctuations in the quality of the treated water, making it impossible to consistently meet the standards.
[0003] As the requirements for wastewater treatment quality gradually increase, some simple mechanical devices have begun to be used. However, these devices accumulate in pipes or at the bottom of tanks, causing frequent blockages and uneven chemical dosing. At the same time, there is still no precise control over metering.
[0004] Existing wastewater treatment dosing devices are difficult to spray evenly during dosing, causing the treatment agent to accumulate in one place after spraying and failing to diffuse and react. Therefore, a wastewater treatment agent dosing device is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A wastewater treatment agent dosing device of this utility model includes a container; a first support is fixedly connected to the side wall of the container; a material box is fixedly connected to the side wall of the first support; a pump casing is fixedly connected to the side wall of the first support; a high-pressure pump is fixedly connected to the side wall of the pump casing; a material pipe is fixedly connected to the bottom end of the pump casing; a spray nozzle is fixedly connected to the output end of the material pipe; the material pipe connects to the bottom of an electric push rod; the material box is correspondingly arranged with the material pipe; an electric push rod is fixedly connected to the side wall of the first support; a second support is fixedly connected to the side wall of the first support; a flexible spring is fixedly connected to the side wall of the second support; a baffle is fixedly connected to the top end of the flexible spring; a rotating seat is fixedly connected to the side wall of the first support; a rotating shaft is rotatably connected to the middle of the rotating seat; a material pipe is fixedly connected to the middle of the rotating shaft; a baffle is fixedly connected to the top end of the rotating shaft; the electric push rod is correspondingly arranged with the baffle. Through the above structure, the spray direction and range can be flexibly adjusted, allowing the treatment agent to enter the wastewater at different angles and directions, adding a larger amount of treatment agent at once, and allowing for multiple uses from a single addition.
[0007] Preferably, a third support is fixedly connected to the side wall of the rotating shaft; a flow divider is fixedly connected to the side wall of the third support; the flow divider is located directly below the spray nozzle; the flow divider disperses one stream of treatment agent into two streams, so that when the treatment agent passes through the dispersion baffle, any clumps or other substances that may exist in the treatment agent are dispersed, allowing the treatment agent to cover a wider area in the container, reducing the poor reaction effect caused by the coagulation of the treatment agent. Compared with a single liquid stream, it can be more finely distributed in the wastewater, and the contact area with the wastewater is greatly increased, ensuring that all parts of the wastewater can come into contact with the treatment agent.
[0008] Preferably, the container has a pair of sliding grooves inside; a sliding rod is slidably connected to the side wall of the container through the sliding grooves; a scraper is fixed to the bottom end of the sliding rod; by the friction between the scraper and the bottom of the container, a large amount of sediment that appears at the bottom of the container after the reaction is completed is scraped and concentrated more thoroughly, reducing the difficulty in cleaning sediment residue and thus reducing the adverse effects on subsequent reaction processing.
[0009] Preferably, a pair of dustproof elastic cloths are fixedly connected to the top of the rotating seat; a dustproof elastic cloth is fixedly connected to the side wall of the baffle; the dustproof elastic cloths are correspondingly arranged with the baffle; the dustproof elastic cloths can prevent particulate impurities from entering the interior of the rotating seat, reduce friction and wear between the rotating seat and the rotating shaft, which would lead to an increase in the surface roughness of the rotating shaft and a decrease in dimensional accuracy, and reduce the problem of the rotating seat and the rotating shaft swaying and jamming due to particulate impurities entering the rotating seat.
[0010] Preferably, a second scale line is fixed to the inner side wall of the container; a first scale line is fixed to the inner side wall of the feed box; by observing the first and second scale lines together, a precise quantitative standard can be provided when adding sewage and treatment agents, which helps to maintain a stable treatment effect. This is crucial for removing pollutants and adjusting water quality. A stable addition amount can make the treated water quality and other indicators more consistently reach the expected standards. There is no need to perform complex measurements or estimations. It is only necessary to observe the corresponding position of the liquid level in the container and feed box with the scale line to quickly determine whether the addition amount meets the requirements.
[0011] Preferably, a protective cover is fixed to the top of the container; the protective cover has a slot at one end near the first support; the protective cover is correspondingly set to the container; the protective cover can block the splashed treatment agent, reducing the treatment agent from splashing out of the container and causing pollution to the working environment; the protective cover can also be removed after the dosing treatment is completed, which facilitates the subsequent treatment of wastewater impurities.
[0012] The advantages of this utility model are:
[0013] 1. The wastewater treatment agent dosing device of this utility model allows for flexible adjustment of the spray direction and range through the cooperation of an electric actuator and a flexible spring. This enables the treatment agent to enter the wastewater at different angles and directions, reducing the problem of uneven mixing of the treatment agent in the container caused by the traditional single spray direction. The treatment agent can be more evenly dispersed in the wastewater, fully contacting and reacting with the pollutants in the wastewater. A larger amount of treatment agent can be added at one time through the material box, allowing for multiple uses from a single addition.
[0014] 2. The wastewater treatment agent dosing device of this utility model disperses a single flow of treatment agent into two streams through a diversion plate. When the treatment agent passes through the dispersion baffle, any clumps or other substances that may be present in the treatment agent are dispersed, allowing the treatment agent to cover a wider area in the container. This reduces the poor reaction effect caused by the coagulation of the treatment agent. Compared with a single liquid stream, it can be more finely distributed in the wastewater, and the contact area with the wastewater is greatly increased, ensuring that all parts of the wastewater can come into contact with the treatment agent.

[0022] 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 scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, a wastewater treatment agent dosing device includes a container 1; a first support 11 is fixedly connected to the side wall of the container 1; a material box 12 is fixedly connected to the side wall of the first support 11; a pump housing 13 is fixedly connected to the side wall of the first support 11; a high-pressure pump 14 is fixedly connected to the side wall of the pump housing 13; a material pipe 15 is fixedly connected to the bottom end of the pump housing 13; a spray nozzle 110 is fixedly connected to the output end of the material pipe 15; the material pipe 15 is connected to the lower part of the electric push rod 16; the material box 12 and the material pipe 15 are correspondingly arranged; the first An electric actuator 16 is fixedly connected to the side wall of the first bracket 11; a second bracket 17 is fixedly connected to the side wall of the first bracket 11; a flexible spring 18 is fixedly connected to the side wall of the second bracket 17; a baffle 111 is fixedly connected to the top of the flexible spring 18; a rotating seat 112 is fixedly connected to the side wall of the first bracket 11; a rotating shaft 19 is rotatably connected to the middle of the rotating seat 112; a material pipe 15 is fixedly connected to the middle of the rotating shaft 19; a baffle 111 is fixedly connected to the top of the rotating shaft 19; the electric actuator 16 is correspondingly arranged with the baffle 111; during operation, the treatment agent is added... The agent is drawn into the material box 12, and the high-pressure pump 14 is started, driving the material pipe 15 to draw the treatment agent from the material box 12 into the nozzle 110 for spraying. As the treatment agent is sprayed from the nozzle 110, it pushes the electric push rod 16. The end of the electric push rod 16 presses against the side wall of the baffle 111, causing the baffle 111 to move and rotate the shaft 19. The rotation of the shaft 19 causes the nozzle 110 to swing, oscillating and ejecting the treatment agent from the nozzle 110 into different areas. The electric push rod 16 retracts, and the flexible spring 18 presses against one side of the baffle 111 using its own elasticity. The movable baffle 111 swings towards the electric push rod 16, and the spray nozzle 110 can swing again to spray the treatment agent to different positions. The spray direction and range can be flexibly adjusted by the electric push rod 16 and the flexible spring 18, so that the treatment agent can enter the sewage at different angles and directions. This reduces the problem of uneven mixing of the treatment agent in the container 1 caused by the traditional single spray direction. The treatment agent can be more evenly dispersed in the sewage and fully contact and react with the pollutants in the sewage. A large amount of treatment agent can be added at one time through the material box 12, and it can be used multiple times after one addition.
[0025] like Figures 1 to 2As shown, a third support 2 is fixedly connected to the side wall of the rotating shaft 19; a flow divider 21 is fixedly connected to the side wall of the third support 2; the flow divider 21 is located directly below the spray nozzle 110; during operation, the treatment agent sprayed from the spray nozzle 110 can be dispersed into two streams by passing above the flow divider 21. The flow divider 21 disperses the treatment agent stream into two streams, so that when the treatment agent passes through the dispersion baffle 111, any clumps or other substances that may exist in the treatment agent are dispersed, allowing the treatment agent to cover a wider area in the container 1, reducing the poor reaction effect caused by the coagulation of the treatment agent. Compared with a single liquid stream, it can be more finely distributed in the sewage, and the contact area with the sewage is greatly increased, ensuring that all parts of the sewage can come into contact with the treatment agent.
[0026] like Figure 3 As shown, a pair of sliding grooves 32 are provided inside the container 1; a sliding rod 3 is slidably connected to the side wall of the container 1 through the sliding grooves 32; a scraper 31 is fixedly connected to the bottom end of the sliding rod 3; during operation, a pulling force is applied to the sliding rod 3, which drives the scraper 31 to slide through the sliding grooves 32. The scraper 31 rubs against the bottom of the container 1. Through the friction between the scraper 31 and the bottom of the container 1, a large amount of sediment that appears at the bottom of the container 1 after the reaction is completed is scraped and concentrated more thoroughly, reducing the sediment residue that is not easy to clean and thus has an adverse effect on subsequent reaction processing.
[0027] like Figures 1 to 5 As shown, a pair of dustproof elastic cloths 4 are fixedly connected to the top of the rotating seat 112; a dustproof elastic cloth 4 is fixedly connected to the side wall of the baffle 111; the dustproof elastic cloth 4 is correspondingly arranged with the baffle 111; during operation, when the electric push rod 16 pushes the baffle 111 in the swing arm process, impurities and particles will enter the interior of the rotating seat 112. The dustproof elastic cloth 4 can block the particles and impurities from entering the interior of the rotating seat 112, reduce the friction and wear between the rotating seat 112 and the rotating shaft 19, which leads to an increase in the surface roughness of the rotating shaft 19 and a decrease in dimensional accuracy, and reduces the problem of the rotating seat 112 and the rotating shaft 19 swinging and jamming due to the entry of particles and impurities into the rotating seat 112.
[0028] like Figures 4 to 5As shown, a second scale line 51 is fixed to the inner side wall of the container 1; a first scale line 5 is fixed to the inner side wall of the material box 12. During operation, when the treatment agent is added to the material box 12, the amount of treatment agent can be directly observed through the second scale line 51. When sewage is added to the container 1, the amount of sewage can also be observed through the first scale line 5. By observing the first scale line 5 and the second scale line 51 together, a precise quantitative standard can be provided when adding sewage and treatment agent, which helps to maintain a stable treatment effect. This is crucial for removing pollutants and adjusting water quality. A stable addition amount can make the water quality and other indicators after treatment more stably reach the expected standard. There is no need to perform complex measurements or estimations. It is only necessary to observe the corresponding position of the liquid level in the container 1 and the material box 12 with the scale line to quickly determine whether the addition amount meets the requirements.
[0029] like Figures 4 to 5 As shown, a protective cover 6 is fixed to the top of the container 1; a slot 61 is opened at one end of the protective cover 6 near the first support 11; the protective cover 6 is set correspondingly to the container 1; during operation, the spray nozzle 110 and the diversion plate 21 work together to spray the powerful treatment agent into the sewage, which will cause splashing. The protective cover 6 can block the splashed treatment agent, reducing the treatment agent from splashing out of the container 1 and causing pollution to the working environment. The protective cover 6 can also be removed after the dosing treatment is completed, which is convenient for subsequent treatment of sewage impurities.
[0030] Working principle: By adding the treatment agent into the material box 12, the high-pressure pump 14 is started, driving the material pipe 15 to draw the treatment agent from the material box 12 and spray it out from the nozzle 110. During the spraying process, the treatment agent pushes the electric push rod 16. The end of the electric push rod 16 presses against the side wall of the baffle 111. The movement of the baffle 111 drives the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 causes the nozzle 110 to swing, spraying the treatment agent from the nozzle 110 into different areas. The electric push rod 16 retracts, and the flexible spring 18, through its own elasticity, presses against one side of the baffle 111, causing the baffle 111 to swing towards the electric push rod 16. The nozzle 110 can then swing again, spraying the treatment agent to different positions. The treatment agent sprayed from the nozzle 110 is then... Above the diverter plate 21, the sprayed treatment agent can be dispersed into two streams. A pulling force is applied to the sliding rod 3, which drives the scraper 31 to slide through the sliding groove 32. The scraper 31 rubs against the bottom of the container 1. During the swinging process, the electric push rod 16 pushes the baffle 111. Impurities and particles will enter the rotating seat 112. The dustproof elastic cloth 4 can prevent particles and impurities from entering the rotating seat 112. When the treatment agent is added to the material box 12, the amount of treatment agent can be directly observed through the second scale line 51. When the sewage is added to the container 1, the amount of sewage can also be observed through the first scale line 5. The spray nozzle 110 and the diverter plate 21 work together to spray the powerful treatment agent into the sewage, which will cause splashing. The protective cover 6 can block the splashed treatment agent.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
