Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment dosing technology, specifically a dosing device based on pretreatment to avoid drug flocculation and agglomeration. Background Technology

[0002] The "chemical dosing" step in wastewater treatment is crucial. It involves adding chemical agents to enhance the effectiveness of physical and biological treatment processes, address specific pollutant issues, and ensure that the effluent meets discharge standards or is reused.

[0003] In the prior art, Chinese patent application number CN201210287981.3 discloses a dosing device, including a storage tank and several mixers. A vibrating motor is installed inside the storage tank. One end of each mixer is connected to a pneumatic diaphragm pump. The storage tank is connected to the mixers via a control valve. The control valve includes a star-shaped ash discharge valve, a manual flap valve, and a dispensing valve. The manual flap valve is connected to the storage tank, and the dispensing valve is connected to the mixers. A star-shaped ash discharge valve is installed between the manual flap valve and the dispensing valve. The device allows for automatic or manual control of material addition, is easy to operate, has a high degree of automation, and greatly improves the efficiency of wastewater treatment. Furthermore, because a control valve is installed between the storage tank and the control valve, material discharge is smooth, effectively controlling the material addition speed and preventing clogging of pipes and valves, making it convenient to use.

[0004] Based on the above information, it can be seen that in existing technologies, the purpose of adding medicine is generally achieved by quantitative release through a storage tank. However, in actual use, the medicine may flocculate during long-term storage due to factors such as temperature, and the flocculated medicine will affect normal use. Utility Model Content

[0005] The purpose of this invention is to provide a dosing device based on pretreatment to avoid drug flocculation and agglomeration, so as to solve the problem of drug flocculation affecting use mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dosing device based on pretreatment to avoid drug flocculation and agglomeration, comprising a support frame placed horizontally on the ground, two drug storage tanks fixedly installed on the inner side of the support frame by bolts, and a sealing cap fixedly installed on the top of the drug storage tanks, an inlet pipe with a pump body fixedly installed on the upper surface of the sealing caps, and an outlet pipe with a valve fixedly installed on the lower surface of the drug storage tanks; a filter plate is provided at the upper end inside the drug storage tanks, and an mounting platform is fixedly installed on the upper surface of the filter plate, the mounting platform being slidably installed inside a limiting block inside the drug storage tanks, and the filter plate being configured as a conical structure, with a cleaning mechanism for cleaning its surface provided on the inner side of the filter plate; a negative pressure pump is fixedly installed on the lower surface of the sealing caps.

[0007] Preferably, the cleaning mechanism includes a cleaning scraper fixedly installed on the inner wall of the medicine storage tank, and the lower surface of the cleaning scraper is in contact with the upper surface of the filter plate.

[0008] Preferably, a horizontally arranged rotating shaft is rotatably installed at the upper end of the inside of the medicine storage tank, and the rotating shaft is driven to rotate by a drive motor fixedly installed above the support frame.

[0009] Preferably, a friction roller with a rough surface is coaxially fixed to the outside of the rotating shaft, and the outer surface of the friction roller is in contact with and rubs against the upper surface of the mounting platform.

[0010] Preferably, a collection cylinder that communicates with the filter plate is fixedly installed below it, and a stirring rod is fixedly installed on the lower surface of the collection cylinder.

[0011] Preferably, a first air inlet pipe and a second air inlet pipe are connected below the negative pressure pump, and the opening and closing of the first air inlet pipe and the second air inlet pipe are controlled separately.

[0012] Preferably, the negative pressure pump is connected to a discharge pipe on its side, and the lower end of the second air inlet pipe corresponds to the inside of the collection cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the dosing device based on pretreatment to avoid drug flocculation and agglomeration adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The agent is injected into the storage tank through the feed pipe. When needed, the agent is discharged from the discharge pipe into the sewage treatment tank through the valve connected to the discharge pipe to achieve the purpose of adding the agent. During this process, the filter plate in the storage tank is used to filter the agent to remove impurities and some flocs.

[0015] Furthermore, the drive motor drives the rotating shaft to rotate, and during the rotation of the rotating shaft, the friction rollers on its outside rotate synchronously. The friction force on the surface of the friction rollers drives the mounting platform to rotate, thereby causing the mounting platform to drive the filter plate to rotate. At this time, the cleaning scraper fixedly installed on the inner wall of the medicine storage tank is used to clean the inner wall of the filter plate.

[0016] Furthermore, the impurities removed fall into the collection cylinder below under their own gravity and are collected. When the filter plate rotates, it drives the stirring rod below to rotate through the collection cylinder, which stirs the agent and reduces subsequent flocculation.

[0017] 2. Turn on the negative pressure pump to extract air through the first connecting pipe, thereby creating a negative pressure state inside the medicine storage tank to eliminate air bubbles. The impurities collected in the collection cylinder can be discharged through the second connecting pipe to achieve the purpose of cleaning. During this process, the first and second connecting pipes are controlled and operate independently. Attached Figure Description

Detailed Implementation

[0026] 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 protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-5To achieve the purpose of filtering the medicine, this embodiment provides the following technical solution, specifically: a support frame 1 placed horizontally on the ground; two medicine storage tanks 2 are fixedly installed inside the support frame 1 using bolts; a sealing cap 3 is fixedly installed at the top of each medicine storage tank 2; an inlet pipe 4 with a pump body is fixedly installed on the upper surface of the sealing cap 3; and an outlet pipe 5 with a valve is fixedly installed on the lower surface of each medicine storage tank 2; a filter plate 6 is provided at the upper end inside the medicine storage tank 2; and an installation platform 7 is fixedly installed on the upper surface of the filter plate 6. The installation platform 7 is slidably installed within a limiting block 8 inside the medicine storage tank 2. The filter plate 6 is set as a cone structure. A cleaning mechanism for cleaning its surface is set on the inner side of the filter plate 6. The cleaning mechanism includes a cleaning scraper 14 fixedly installed on the inner wall of the medicine storage tank 2. The lower surface of the cleaning scraper 14 is in contact with the upper surface of the filter plate 6. A horizontally arranged rotating shaft 9 is rotatably installed at the upper end of the inside of the medicine storage tank 2. The rotating shaft 9 is driven to rotate by a drive motor 11 fixedly installed on the upper part of the support frame 1. A rough friction roller 10 is coaxially fixedly installed on the outside of the rotating shaft 9. The outer surface of the friction roller 10 is in contact with the upper surface of the mounting platform 7 for friction.

[0028] When using the device, the required medicine is first injected into the storage tank 2 through the feed pipe 4. During injection, the medicine is filtered by the filter plate 6 inside the storage tank 2 to remove impurities. At the same time, the drive motor 11 above the support frame 1 is turned on, and the drive motor 11 drives the rotating shaft 9 to rotate. During the rotation of the rotating shaft 9, the friction roller 10 outside it rotates synchronously. At this time, under the friction force between the friction roller 10 and the mounting platform 7, the mounting platform 7 drives the filter plate 6 to rotate (the mounting platform 7 is slidably installed with the limit block 8, so the mounting platform 7 can rotate under the guidance of the limit block 8). When the filter plate 6 rotates, the cleaning scraper 14 fixedly installed on the inner wall of the storage tank 2 scrapes and cleans the upper surface of the filter plate 6.

[0029] Example 2: Please refer to Figure 3 In order to achieve the purpose of preventing subsequent flocculation by stirring, this embodiment provides the following technical solution, specifically: a collection cylinder 12 connected to the filter plate 6 is fixedly installed below the filter plate 6, and a stirring rod 13 is fixedly installed on the lower surface of the collection cylinder 12.

[0030] Impurities removed from the upper surface of the filter plate 6 fall into the collection cylinder 12 below under its own gravity and are collected. When the filter plate 6 rotates, it drives the stirring rod 13 to rotate through the collection cylinder 12, which stirs the medicine inside the storage tank 2 to prevent flocculation from occurring later.

[0031] Example 3: Please refer to Figures 6-7In order to achieve the purpose of defoaming, this embodiment provides the following technical solution, which specifically discloses: a negative pressure pump 15 is fixedly installed on the lower surface of the sealing cover 3, and a first air inlet pipe 16 and a second air inlet pipe 17 are connected below the negative pressure pump 15. The opening and closing of the first air inlet pipe 16 and the second air inlet pipe 17 are controlled separately. The side of the negative pressure pump 15 is connected to the discharge pipe 18, and the lower end of the second air inlet pipe 17 corresponds to the inside of the collection cylinder 12.

[0032] After the medicine is added into the storage tank 2, the negative pressure pump 15 is turned on. At this time, the negative pressure pump 15 draws air through the first air inlet pipe 16 and extracts some of the air in the storage tank 2, so that a negative pressure is formed inside the storage tank 2. Under the action of negative pressure, the purpose of eliminating bubbles is achieved. When the liquid level is lower than the filter plate 6 after the medicine has been used for a period of time, the negative pressure pump 15 draws air through the second air inlet pipe 17. At this time, the impurities collected in the collection cylinder 12 are drawn in and discharged from the discharge pipe 18.
