Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical pretreatment technology, specifically to a pharmaceutical pretreatment device for wastewater treatment. Background Technology

[0002] In the wastewater treatment process, the pretreatment of chemicals is a key step to ensure the efficient and stable operation of the entire treatment process. Traditional wastewater treatment chemical pretreatment devices have revealed some shortcomings in practical applications and urgently need to be improved.

[0003] In terms of mixing chemicals and wastewater, the mixing effect of traditional devices is not satisfactory. Chemicals often fall directly into the wastewater without an effective premixing mechanism. The contact area and time between chemicals and wastewater are limited, making it difficult to achieve sufficient mixing. This results in uneven distribution of chemicals in the wastewater and also makes it easy for them to clump or agglomerate. Traditional devices lack effective dispersion methods, and clumped chemicals cannot fully dissolve and react, further reducing the pretreatment effect and affecting the progress of chemical reactions. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a pretreatment device for wastewater treatment, which solves the problem of easy clumping or agglomeration when mixing chemicals and wastewater.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pretreatment device for wastewater treatment includes: a mixing tank, with a feed pipe fixedly connected to the inner wall of the top of the mixing tank and a motor fixedly connected to the outer wall of the top of the mixing tank; and a feeding structure, with its outer wall fixedly connected to the inner wall of the mixing tank. The feeding structure includes a feeding hopper, with symmetrically symmetrically opened grooves on the inner wall of the feeding hopper, symmetrically slidably connected opening and closing plates on the inner walls of the grooves, a connecting plate fixedly connected to the outer wall of the opening and closing plates, symmetrically fixedly connected connecting blocks on the outer wall of the feeding hopper, a bidirectional threaded rod rotatably connected to the inner wall of the connecting blocks, and a guide plate fixedly connected to the outer wall of the bottom of the feeding hopper.

[0009] Preferably, the outer wall of the bidirectional threaded rod is threadedly connected to the inner wall of the connecting plate, and a throttle handle is symmetrically fixedly connected to the outer wall of the bidirectional threaded rod. By rotating the throttle handle on the bidirectional threaded rod, since the outer wall of the bidirectional threaded rod is threadedly connected to the inner wall of the connecting plate, and the connecting plate is fixedly connected to the opening and closing plate, the rotation of the bidirectional threaded rod along the connecting block will cause the two opening and closing plates to slide relative to or opposite to each other along the groove on the inner wall of the feed hopper.

[0010] Preferably, a level gauge is fixedly connected to the outer wall of the mixing tank, a discharge pipe is fixedly connected to the inner wall of the bottom of the mixing tank, a water pump is fixedly connected to the outer wall of the mixing tank, a suction pipe is fixedly connected to the outer wall of the water pump, a spraying bend is fixedly connected to the outer wall of the water pump on the side away from the suction pipe, and a feed inlet is opened on the outer wall of the top of the level gauge.

[0011] Preferably, the inner wall of the feed inlet is fixedly connected to the outer wall of the feed hopper, the outer wall of the spray pipe is fixedly connected to the inner wall of the top of the mixing tank, and the outer wall of the extraction pipe is fixedly connected to the inner wall of the bottom of the mixing tank. The spray pipe is located below the guide plate. After the water pump is started, sewage is drawn from the bottom of the mixing tank through the extraction pipe and then sprayed back into the mixing tank through the spray pipe. The spray pipe is located below the guide plate, so that the agent can first come into contact with and mix with the sewage. The agent will be flushed into the sewage in the mixing tank by the sewage sprayed out by the spray pipe, thereby improving the mixing uniformity of the agent.

[0012] Preferably, a rotating shaft is rotatably connected to the inner wall of the bottom of the motor, a beater plate is fixedly connected to the outer wall of the rotating shaft, and stirring blades are symmetrically fixedly connected to the outer wall of the rotating shaft.

[0013] Preferably, the tapping plate is positioned above the stirring blades, and the outer wall of the rotating shaft is rotatably connected to the inner wall of the top of the mixing tank. The tapping plate, positioned above the stirring blades, can tap the pre-mixed agents above during rotation, which helps to break up any clumps or agglomerates that may form in the agents, allowing the agents to fall more dispersedly into the wastewater in the mixing tank. The stirring blades then stir the agents in the mixing tank, ensuring that the agents are fully mixed.

[0014] (III) Beneficial Effects

[0015] This invention provides a chemical pretreatment device for wastewater treatment. It has the following beneficial effects:

[0016] (i) The mixing tank, through the spray nozzle and the beater plate, the spray nozzle is set below the guide plate, so that the agent entering from the feed hopper can first come into contact with and mix with the sewage sprayed from the spray nozzle during the falling process, which increases the contact area and time between the agent and the sewage, and promotes the initial mixing. The motor drives the rotating shaft to rotate, and the beater plate located above can beat the pre-contacted and mixed agent when rotating, effectively breaking up any clumps or agglomerates that may be formed by the agent, so that the agent is more evenly dispersed into the sewage in the mixing tank, accelerating the chemical reaction between the agents and significantly improving the pretreatment effect.

[0017] (ii) The feeding structure uses a bidirectional threaded rod. By rotating the handle on the bidirectional threaded rod, the connecting plate connected to it is driven by the opening and closing plate to slide along the slide groove, thereby realizing the control of the opening degree of the feeding hopper. This adjustable feeding method can flexibly control the feeding speed and flow rate of the agent according to the actual processing needs, ensuring the accuracy and stability of the agent addition.

[0025] 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.

[0026] Please see Figure 1-6This utility model provides a technical solution: a pretreatment device for wastewater treatment, comprising: a mixing tank 1, a feed pipe 2 fixedly connected to the inner wall of the top of the mixing tank 1, a motor 3 fixedly connected to the outer wall of the top of the mixing tank 1, and a feeding structure 4, the outer wall of the feeding structure 4 being fixedly connected to the inner wall of the mixing tank 1; the feeding structure 4 includes a feeding hopper 41, the inner wall of the feeding hopper 41 being symmetrically provided with a sliding groove 42, the inner wall of the sliding groove 42 being symmetrically slidably connected with an opening and closing plate 43, the outer wall of the opening and closing plate 43 being fixedly connected with a connecting plate 44, the outer wall of the feeding hopper 41 being symmetrically fixedly connected with a connecting block 45, the inner wall of the connecting block 45 being rotatably connected with a bidirectional threaded rod 46, and the outer wall of the bottom of the feeding hopper 41 being fixedly connected with a guide plate 47.

[0027] The outer wall of the bidirectional threaded rod 46 is threadedly connected to the inner wall of the connecting plate 44. A throttle is symmetrically fixedly connected to the outer wall of the bidirectional threaded rod 46. By rotating the throttle on the bidirectional threaded rod 46, since the outer wall of the bidirectional threaded rod 46 is threadedly connected to the inner wall of the connecting plate 44, and the connecting plate 44 is fixedly connected to the opening and closing plate 43, the rotation of the bidirectional threaded rod 46 along the connecting block 45 will cause the two opening and closing plates 43 to slide relative to each other or in opposite directions along the sliding groove 42 on the inner wall of the feed hopper 41.

[0028] A level gauge 11 is fixedly connected to the outer wall of the mixing tank 1. A discharge pipe 12 is fixedly connected to the inner wall of the bottom of the mixing tank 1. A water pump 13 is fixedly connected to the outer wall of the mixing tank 1. A suction pipe 14 is fixedly connected to the outer wall of the water pump 13. A spraying bend pipe 15 is fixedly connected to the outer wall of the water pump 13 on the side away from the suction pipe 14. An inlet 16 is opened on the outer wall of the top of the level gauge 11.

[0029] The inner wall of the feed inlet 16 is fixedly connected to the outer wall of the feed hopper 41, the outer wall of the spray pipe 15 is fixedly connected to the inner wall of the top of the mixing tank 1, and the outer wall of the extraction pipe 14 is fixedly connected to the inner wall of the bottom of the mixing tank 1. The spray pipe 15 is located below the guide plate 47. After the water pump 13 starts, sewage is drawn from the bottom of the mixing tank 1 through the extraction pipe 14, and then the sewage is sprayed back into the mixing tank 1 through the spray pipe 15. The spray pipe 15 is located below the guide plate 47, so that the agent can first come into contact with the sewage and mix. The agent will be flushed into the sewage in the mixing tank 1 by the sewage sprayed out by the spray pipe 15, thereby improving the mixing uniformity of the agent.

[0030] A rotating shaft 31 is rotatably connected to the inner wall of the bottom of the motor 3, a beater 32 is fixedly connected to the outer wall of the rotating shaft 31, and stirring blades 33 are symmetrically fixedly connected to the outer wall of the rotating shaft 31.

[0031] The beater plate 32 is positioned above the stirring blade 33. The outer wall of the rotating shaft 31 is rotatably connected to the inner wall of the top of the mixing tank 1. The beater plate 32, positioned above the stirring blade 33, can beat the pre-mixed agent above during rotation, which helps to break up any clumps or agglomerates that may form in the agent, allowing the agent to fall more dispersedly into the wastewater in the mixing tank 1. The stirring blade 33 then stirs the agent in the mixing tank 1, ensuring that the agent is fully mixed.

[0032] In use, wastewater is fed into the mixing tank 1 through the feed pipe 2. Then, the water pump 13 is started to circulate the wastewater in the mixing tank 1 and spray it back into the mixing tank 1 through the spray pipe 15. The spray pipe 15 is located below the guide plate 47. When the feed structure 4 is opened, the agent can enter the mixing tank 1 from the feed hopper 41. During the process of the agent falling, it first comes into contact with the wastewater flowing out of the spray pipe 15 and then flows into the wastewater in the mixing tank 1. The motor 3 is started to stir the agent in the mixing tank 1 so that the agent is fully mixed.

[0033] First, wastewater is fed into the mixing tank 1 through the feed pipe 2. Then, the powdered medicine is poured into the feed hopper 41. The operator rotates the handle on the bidirectional threaded rod 46. Since the outer wall of the bidirectional threaded rod 46 is threadedly connected to the inner wall of the connecting plate 44, and the connecting plate 44 is fixedly connected to the opening and closing plate 43, the rotation of the bidirectional threaded rod 46 along the connecting block 45 will cause the two opening and closing plates 43 to slide relative to each other or in opposite directions along the sliding groove 42 on the inner wall of the feed hopper 41. When the two opening and closing plates 43 slide in opposite directions, the feed hopper 41 opens, and the medicine can enter the mixing tank 1 from the guide plate 47 at the bottom of the feed hopper 41 through the feed port 16.

[0034] After the water pump 13 on the outer wall of the mixing tank 1 is started, sewage is drawn from the bottom of the mixing tank 1 through the extraction pipe 14, and then the sewage is sprayed back into the mixing tank 1 through the spray pipe 15. The spray pipe 15 is set below the guide plate 47, so that the agent can come into contact with the sewage and mix first. The agent will be flushed into the sewage in the mixing tank 1 by the sewage sprayed out by the spray pipe 15, thereby improving the mixing uniformity of the agent.

[0035] Simultaneously, the motor 3 is started, which drives the rotating shaft 31 to rotate. The rotating shaft 31 is fixedly connected to the tapping plate 32 and the stirring blade 33. As the rotating shaft 31 rotates, the tapping plate 32 and the stirring blade 33 also rotate. The tapping plate 32 is set above the stirring blade 33. During the rotation, it can tap the pre-contacted and mixed agent above, which helps to break up any clumps or agglomerates that may be formed by the agent, so that the agent can fall more dispersed into the sewage in the mixing tank 1. The stirring blade 33 stirs the agent in the mixing tank 1, so that the agent is fully mixed, accelerates the chemical reaction between the agents, and improves the pretreatment effect.

[0036] The level gauge 11 on the outer wall of the mixing tank 1 can monitor the liquid level of the agent in the mixing tank 1 in real time. After the agent pretreatment is completed, the discharge pipe 12 on the inner wall of the bottom of the mixing tank 1 can discharge the treated agent for subsequent sewage treatment processes.
