Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of MBR membrane cleaning, and more specifically to an MBR membrane cleaning agent dosing device. Background Art
[0002] MBR membrane bioreactor is a new water treatment technology that combines membrane separation unit with biological treatment unit. It uses membrane components to replace secondary sedimentation tanks to maintain high active sludge concentration in bioreactors to reduce the land occupation of sewage treatment facilities and reduce the amount of sludge by maintaining low sludge load. As an important part of the reactor during wastewater treatment, MBR membrane needs to be cleaned regularly to maintain its optimal performance.
[0003] When colloids or dissolved microbial metabolites in the wastewater are adsorbed on the surface of the MBR membrane, the MBR membrane needs to be chemically cleaned to completely remove the colloids and dissolved microbial metabolites adsorbed on the surface of the MBR membrane. When chemically cleaning the MBR membrane, chemical cleaning agents are required. Common MBR membrane cleaning agents are citric acid and oxalic acid, both of which are highly toxic. Their solutions or dusts can damage the skin, mucous membranes and eyes. Inadvertent ingestion can also cause inflammation of the gastrointestinal tract, and in severe cases, shock and death. Long-term inhalation of dust can also cause chronic poisoning. Therefore, workers need to wear a full set of protective clothing when applying MBR membrane cleaning agents.
[0004] However, when workers wear full sets of protective clothing, it is difficult to open bags and add chemicals. In addition, the process of adding chemicals into the MBR cleaning tank is likely to cause dust to fly, resulting in dust pollution. Workers are prone to inhaling chemical dust during subsequent operations, and long-term inhalation is more likely to cause chronic poisoning. Utility Model Content
[0005] In order to overcome the problem in the prior art that, when cleaning the MBR membrane, workers wearing protective clothing are inconvenient to add cleaning agents and dust pollution is easily caused by flying dust, the utility model provides an MBR membrane cleaning agent adding device. In this scheme, when adding the MBR membrane cleaning agent, workers do not need to wear a full set of protective clothing, the operation is simple and convenient, and dust pollution caused by flying dust can be avoided.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: an MBR membrane cleaning agent dosing device, comprising a shell, an upper cover, a discharge plate, a bag breaking part, a driving part and a material guiding pipe, the upper cover is detachably connected to the top of the shell, one end of the discharge plate for supporting the bagged cleaning agent is fixedly connected to the side wall of the shell inner cavity, and the other end is inclined toward the bottom of the shell inner cavity, the gap between one end of the discharge plate close to the bottom of the shell inner cavity and the shell is a discharge port, the bag breaking part is used to puncture the packaging bag at the discharge port, the driving part is used to drive the bag breaking part to puncture the packaging bag, one end of the material guiding pipe is connected to the bottom of the shell inner cavity, and the other end is connected to the MBR membrane cleaning tank.
[0007] When the device is working, open the upper cover on the shell, place the bagged MBR membrane cleaning agent on the discharge plate, and then cover the upper cover of the shell on the shell to form a closed inner cavity of the shell. Since the discharge plate is inclined, the bagged MBR membrane cleaning agent will move toward the lower feed port on the discharge plate until the bagged MBR membrane cleaning agent rolls to abut against the side wall of the shell. At this time, the bagged MBR membrane cleaning agent remains stationary on the discharge plate, and a part of the packaging bag protrudes downward at the discharge port. Then the staff operates the driving part to drive the bag breaking part to move toward the lower feed port through the driving part until the bag breaking part pierces the packaging bag at the discharge port, and then operates the driving part to drive the bag breaking part to reset. At this time, the MBR cleaning agent spills out of the hole in the packaging bag due to its own gravity, enters the inner cavity of the shell, and is then transported to the MBR membrane cleaning tank through the guide pipe to complete the addition of the MBR membrane cleaning agent.
[0008] After the device of this scheme completes the delivery of the bagged MBR membrane cleaning agent into the shell, it can complete the bag breaking and delivery of the MBR membrane cleaning agent in the shell, without the need for workers to wear a full set of protective clothing. The operation is simple and convenient. The dust generated during the bag breaking and delivery process is accumulated in the inner cavity of the shell and will not dissipate outward, avoiding dust flying everywhere and causing dust pollution. At the same time, the discharge plate in the shell is tilted to one side, so that it still takes some time for the bagged MBR membrane cleaning agent to reach the designated bag breaking position after it is placed. After the bagged MBR membrane cleaning agent is placed, the cover can be closed before it reaches the designated position, further avoiding the dust in the inner cavity of the shell from flying everywhere when the bag is opened.
[0009] Preferably, it also includes a guide plate, the guide pipe passes through the bottom of the shell side wall and is connected to the shell inner cavity, the side wall where the guide pipe is located on the shell and the side wall where the feed opening is located are respectively located on both sides of the shell, one end of the guide plate is fixedly connected to the side wall where the upper and lower feed openings of the shell are located, and the other end is inclined to the feed opening of the guide pipe. After the guide plate is set, the MBR membrane cleaning agent that falls from the hole in the packaging bag into the shell inner cavity will fall onto the guide plate, and under the action of its own gravity, it will move along the guide plate to the guide pipe, so as to achieve the purpose of transferring the MBR membrane cleaning agent in the shell inner cavity to the guide pipe.
[0010] Preferably, the angle a between the discharge plate and the horizontal plane is 30°-70°; the angle b between the guide plate and the horizontal plane is 30°-60°.

The upper cover 2 is detachably connected to the top of the shell 1. One end of the discharge plate 3 for supporting the bagged cleaning agent is fixedly connected to the side wall of the inner cavity of the shell 1, and the other end is inclined toward the bottom of the inner cavity of the shell 1. The gap between one end of the discharge plate 3 close to the bottom of the inner cavity of the shell 1 and the shell 1 is a discharge port 7. The bag breaking part 4 is used to puncture the packaging bag at the discharge port 7. The driving part 5 is used to drive the bag breaking part 4 to puncture the packaging bag. One end of the guide pipe 6 is connected to the bottom of the inner cavity of the shell 1, and the other end is connected to the MBR membrane cleaning tank.
[0032] The working principle or working process of this embodiment: when the device is working, open the upper cover 2 on the shell 1, place the bagged MBR membrane cleaning agent on the discharge plate 3, and then cover the upper cover 2 of the shell 1 on the shell 1, so that the shell 1 forms a closed inner cavity. Since the discharge plate 3 is inclined, the bagged MBR membrane cleaning agent will move toward the lower feed port 7 on the discharge plate 3 until the bagged MBR membrane cleaning agent rolls to abut against the side wall of the shell 1. At this time, the bagged MBR membrane cleaning agent remains stationary on the discharge plate 3, and a part of the packaging bag protrudes downward at the discharge port 7. Then the staff operates the driving part 5, and drives the bag breaking part 4 to move toward the lower feed port 7 through the driving part 5 until the bag breaking part 4 pierces the packaging bag at the discharge port 7, and then operates the driving part 5 to drive the bag breaking part 4 to reset. At this time, the MBR cleaning agent spills out from the hole on the packaging bag due to its own gravity, enters the inner cavity of the shell 1, and is then transported to the MBR membrane cleaning tank through the guide pipe 6, completing the addition of the MBR membrane cleaning agent.
[0033] Beneficial effects of this embodiment: After the device of this scheme completes the delivery of the bagged MBR membrane cleaning agent into the shell 1, it can complete the bag breaking and delivery of the MBR membrane cleaning agent in the shell 1, without the need for workers to wear a full set of protective clothing, and the operation is simple and convenient. The dust generated during the bag breaking and delivery process is accumulated in the inner cavity of the shell 1 and will not escape outward, thereby avoiding dust flying everywhere and causing dust pollution. At the same time, the discharge plate 3 in the shell 1 is tilted to one side, so that it still takes some time for the bagged MBR membrane cleaning agent to reach the designated bag breaking position after it is placed. After the bagged MBR membrane cleaning agent is placed, the upper cover 2 can be closed before it reaches the designated position, further avoiding the dust in the inner cavity of the shell 1 from flying everywhere when the bag is opened.
