[0002] To centrally treat and remove suspended solids and dissolved organic matter in water, a common treatment method is to add PAM to the water body to increase the coagulability and dehydration rate of the sewage, so that the solid pollutants in the sewage precipitate. A typical device is a PAM dosing device.
[0003] On the market, PAM dosing devices usually centrally put PAM powder into the feed bin. After the powder is conveyed to the discharge bin by a conveyor, the powder directly falls into the dissolving mechanism from the discharge port of the discharge bin for dissolution. Since PAM powder is prone to absorb water vapor in the air and cause caking, there is a situation of blocking the discharge port of the discharge bin, and when the powder enters the dosing device body for dissolution, it is easy to appear in small lumps, resulting in a long dissolution time and low efficiency. Summary of the Utility Model

The buffer mechanism has a buffer chamber for dispersing materials and a discharge port communicating with the buffer chamber. The buffer chamber is arranged below the discharge port and communicates with the discharge port.
[0006] According to some embodiments of the utility model, the orientation of the discharge port is parallel to the horizontal direction.
[0007] According to some embodiments of the utility model, the buffer mechanism includes a bottom plate and side plates surrounding the bottom plate. The area surrounded by the bottom plate and the side plates forms the buffer chamber, and a notch is formed on the side plates to form the discharge port.

[0028] The present utility model provides a PAM dosing auxiliary drug dissolving device, Figures 1 - 5 which is a specific embodiment of the PAM dosing auxiliary drug dissolving device provided by the present utility model.
[0029] As Figure 1 , an embodiment of the present utility model provides a PAM dosing auxiliary drug dissolving device 100, including a feeding bin 1, a discharging bin 2, and a material conveying mechanism 3 for conveying materials from the feeding bin 1 to the discharging bin 2. A discharging opening 21 is provided at the bottom of the discharging bin 2. The device further includes a flushing mechanism 4 and a buffering mechanism 5. The flushing mechanism 4 includes a water supply unit and a flushing pipeline 41. One end of the flushing pipeline 41 is connected to the water supply unit, and the other end communicates with the inside of the discharging bin 2 and is tangentially arranged with the inner side wall of the discharging bin 2. The buffering mechanism 5 has a buffering chamber 51 for dispersing materials and a discharging opening 52 communicating with the buffering chamber 51. The buffering chamber 51 is arranged below the discharging opening 21 and communicates with the discharging opening 21.
[0030] In the present utility model, since one end of the flushing pipeline 41 communicates with the inside of the discharging bin 2 and is tangentially arranged with the inner side wall of the discharging bin 2, when materials enter the discharging bin 2, the flushing mechanism 4 will flush the materials from the side, and the flushing direction is the tangential direction, so that a spiral water flow can be formed in the discharging bin 2. The spiral water flow can disperse the materials to avoid blocking the discharging opening 21, and can also accelerate the dissolution rate of the PAM powder. When the spiral water flow continues to flow downward into the buffering chamber 51, it will continue to disperse and dissolve the materials, playing a role of pre-dissolution, and can avoid the appearance of small lumps when dissolving in the subsequent dosing device body 110, thereby improving the subsequent dissolution rate.
[0031] It can be understood that the material conveying mechanism 3 is not specifically limited and can be a belt feeder, a tube chain conveyor, etc. Preferably, in this embodiment, the material conveying mechanism 3 adopts a screw feeder, which can play a certain stirring role during the conveying process. The water supply unit is not specifically limited, as long as it can supply water flow, and it can be a combination of one or more water supply devices such as water pumps, valves, and pipes.
[0032] It should be noted that the arrows in the drawings indicate the flow direction of the material movement.
[0033] Specifically, in some embodiments, the buffer mechanism 5 includes a bottom plate 53 and side plates 54 surrounding the bottom plate 53. The enclosed area formed by the bottom plate 53 and the side plates 54 forms the buffer chamber 51, and a notch is provided on the side plate 54 to form the discharge port 52. When the spiral water flow falls into the buffer chamber 51 through the feeding port 21, it will directly impact the bottom plate 53, and the impact force is used to wash and disperse the material. The side plate 54 can prevent the water flow from splashing out. After the water flow impacts the bottom plate 53, it will continue to flow out through the discharge port 52 on the side plate 54 and enter the interior of the device body 110 through the dosing port of the PAM dosing device 200 for further dissolution. Moreover, the discharge port is provided on the side plate, which changes the outflow direction of the vertically flowing water into the buffer mechanism 5, delays the time of the material and the water flow in the buffer chamber 51, and improves the efficiency of the pre-dissolution of the PAM powder.
[0034] Specifically, in some embodiments, the bottom plate 53 is inclined relative to the horizontal plane, and the inclined direction is away from the feeding port 21. Through the inclined bottom plate 53, the opening area of the discharge port 52 is increased, and further the outflow area of the water flow is increased, so that the water flows into the dosing device body 110 with a larger area, improving the dissolution efficiency of the PAM powder in the dosing device body 110. In addition, it can also facilitate the water flow to flow towards the discharge port 52 under the action of its own gravity and reduce the blockage situation.
[0035] Specifically, in some embodiments, a plurality of flushing pipes 41 are provided and arranged at intervals in the vertical direction on the discharge bin 2. By arranging a plurality of flushing pipes 41 at intervals in the vertical direction, a multi-layer water flow can be formed during the flushing process, thereby increasing the contact area between the water and the material, helping to more comprehensively cover the material, improving the uniformity and efficiency of flushing, and the water flows of multiple pipes can impact the material at different heights simultaneously, forming a stronger impact force. This impact force helps to break the agglomerated state of the material and makes it easier to be flushed.
[0036] Specifically, in some embodiments, the flushing mechanism 4 further includes a flushing pipeline disposed on the buffer mechanism 5. One end of the flushing pipeline is connected to the water supply unit, and the other end communicates with the inside of the discharge bin 2. In this way, the water flow in the flushing pipeline impacts the water flow falling into the buffer chamber 51, which can further disperse the materials and improve the dissolution efficiency of the PAM powder.
[0037] Specifically, in some embodiments, an overflow pipeline 22 is connected to the discharge bin 2. The connection between the overflow pipeline 22 and the discharge bin 2 is located above the connection between the flushing pipeline 41 and the discharge bin 2. Since the PAM powder has a certain viscosity when dissolved in water, there is a situation where the lower material outlet 21 is blocked. When the lower material outlet 21 is blocked, the flowing water can flow out through the overflow pipeline 22 to play an overflow role. Moreover, the connection between the overflow pipeline 22 and the discharge bin 2 is located above the connection between the flushing pipeline 41 and the discharge bin 2. When there is no blockage, it will not affect the process of flushing and dispersing the powder. The other end of the overflow pipeline 22 communicates with the medicine inlet on the PAM dosing device 200, and no material loss will occur.
[0038] Specifically, in some embodiments, a vibration device 6 is provided on the outer wall surface of the feed bin 1 to vibrate the powder in the feed bin 1 and prevent the powder from caking after absorbing water.
[0039] Specifically, in some embodiments, a stirring device is provided in the buffer chamber 51, which can stir the materials to improve the dissolution efficiency. In addition, it can also disperse the caked materials.
[0040] Specifically, in some embodiments, a level gauge 7 is provided in the feed bin 1 to detect the inventory of the materials in the feed bin 1, and then the materials can be increased or decreased according to actual needs.
[0041] Specifically, in some embodiments, an observation window 8 is also embedded on the side wall of the feed bin 1 to observe the material condition in the bin.
[0042] The present utility model also provides a PAM dosing device 200, which includes a device body 110 and the above-mentioned PAM dosing auxiliary dissolution device 100. A medicine inlet is provided on the device body 110, and the medicine inlet communicates with the discharge port 52. Through the flushing mechanism 4, the situation that the lower material outlet 21 of the discharge bin 2 is easily blocked by the PAM powder can be solved. Moreover, before the PAM powder enters the device body 110 for dissolution, it will be pre-dissolved in the buffer chamber 51, greatly improving the dissolution efficiency of the powder and solving the problem that the powder directly falls into the device body 110 for dissolution and forms small lumps, which affects the dissolution.
[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
