[0002] The chemical industry includes two major categories: organic chemicals and inorganic chemicals. Chemical products are diverse and complex in composition, and the wastewater discharged is also diverse. Most of them are highly toxic and difficult to purify. They have a certain accumulation effect in organisms and have obvious oxygen-consuming properties in water bodies, which can easily deteriorate water quality.

[0003] When conducting environmental protection treatment on chemical wastewater, it is necessary to add coagulants, flocculants and other agents into the wastewater. The agents react with the wastewater to produce precipitation and then separate.

[0004] At present, when adding reagents to wastewater, there are generally two methods: one-time addition and multiple addition. When adding once, the batch of reagents is directly added to the wastewater. At this time, the reagents cannot fully contact the wastewater, and some reagents are prone to directly precipitate at the bottom of the wastewater, resulting in poor effect of reagent addition. When adding multiple times, the reagents need to be quantitatively divided into multiple batches. After the previous batch of reagents reacts completely, the next batch of reagents is added for reaction, resulting in a longer overall wastewater treatment time and lower wastewater treatment efficiency.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig.10 , Fig.11 As shown, it is a structural diagram of a chemical wastewater environmental protection treatment device provided by an embodiment of the present invention, comprising a box body 1, the top wall of the box body 1 is provided with a water injection port 11, the side wall of the box body 1 is provided with a drain pipe 12, the bottom wall of the box body 1 is provided with multiple groups of sewage pipes 13, the inner cavity of the box body 1 is rotatably installed with a vertical cylinder 2, the top end of the vertical cylinder 2 extends to the outside of the box body 1 and is fixedly installed with a feed funnel 22, the bottom wall of the box body 1 is fixedly installed with a motor 21, the output shaft of the motor 21 is connected to the bottom end of the vertical cylinder 2, and the surface of the vertical cylinder 2 is fixedly installed with a fixed plate 2 3, the vertical cylinder 2 is rotatably connected to the top wall of the box body 1 through a fixed plate 23, and multiple groups of stirring tubes 3 are fixedly installed at different heights on the surface of the vertical cylinder 2. The multiple groups of stirring tubes 3 are distributed in a ring around the vertical cylinder 2. One end of the stirring tube 3 is provided with an opening connected to the inner cavity of the vertical cylinder 2. The inner cavity of the vertical cylinder 2 is provided with a layered material discharge mechanism 4 that cooperates with the stirring tube 3. The layered material discharge mechanism 4 includes a material distribution component 41, an opening and closing component 42 and a material discharge component 43. The material distribution component 41 is located in the inner cavity of the vertical cylinder 2. The material distribution component 41 is used to store materials at different heights in the inner cavity of the vertical cylinder 2. The opening and closing assembly 42 includes a plurality of baffles 421 and a positioning portion 422. The baffles 421 are slidably connected to the inner wall of the vertical cylinder 2 in the vertical direction. The baffles 421 are relatively distributed with the stirring tube 3. The surface of the baffles 421 is provided with a guide hole 4211 that cooperates with the opening at the end of the stirring tube 3. The positioning portion 422 is located in the feed funnel 22 and is connected to the baffle 421. The positioning portion 422 adjusts the relative position of the guide hole 4211 and the opening at the end of the stirring tube 3 by cooperating with the baffle 421. The discharge assembly 43 includes a sealing tube 431 and a rotating part 432. The sealing tube 431 is rotatably installed on the outside of the stirring tube 3. The bottom wall of the stirring tube 3 is provided with multiple groups of first discharge holes 4311 distributed in parallel. The surface of the sealing tube 431 is provided with multiple groups of second discharge holes 4312 that cooperate with the first discharge holes 4311. The rotating part 432 is located on the outside of the vertical cylinder 2 and is connected to the sealing tube 431. The rotating part 432 is used to control the sealing tube 431 to rotate on the outside of the stirring tube 3 and thereby adjust the relative positions of the first discharge holes 4311 and the second discharge holes 4312.

[0031] Initially, the positioning portion 422 supports and positions the baffle 421 in the inner cavity of the vertical cylinder 2. At this time, the baffle 421 seals the opening at the end of the stirring tube 3. The rotating portion 432 positions the sealing tube 431 outside the stirring tube 3. At this time, the first discharge hole 4311 on the bottom wall of the stirring tube 3 and the second discharge hole 4312 on the surface of the sealing tube 431 are staggered. When in use, the wastewater to be treated is added into the inner cavity of the box body 1 through the water injection port 11, and the medicine to be added is added into the feeding funnel 22 at one time. The medicine moves downward in the inner cavity of the vertical cylinder 2, and the material distribution component 41 can store a certain amount of medicine at different heights in the inner cavity of the vertical cylinder 2. After the medicine is added, the positioning part 422 adjusts the position of the baffle 421 so that the guide hole 4211 on the surface of the baffle 421 is aligned with the opening at the end of the stirring tube 3. At this time, the opening at the end of the stirring tube 3 is in a through state, and the motor 21 drives the vertical cylinder 2 to rotate. When the vertical cylinder 2 rotates, the centrifugal force can be used to transport the medicine stored at the corresponding height in the vertical cylinder 2 to the inner cavity of the stirring tube 3. After the agent is transported to the inner cavity of the stirring tube 3, the rotating part 432 controls the sealing tube 431 to rotate outside the stirring tube 3 and then adjusts the position of the second discharge hole 4312. After the second discharge hole 4312 coincides with the first discharge hole 4311, the agent in the stirring tube 3 passes through the first discharge hole 4311 and the second discharge hole 4312 and can automatically fall into the inner cavity of the box 1 and mix with the wastewater.

[0032] While batches of reagents are discharged from the stirring tubes 3 at different heights, the motor 21 drives the vertical cylinder 2 and the stirring tube 3 to rotate in the inner cavity of the box 1. The stirring tube 3 can fully mix the wastewater and the reagent in the inner cavity of the box 1, and the reagent can fully react with the wastewater to remove impurities, effectively improving the use effect of the reagent and effectively accelerating the treatment efficiency of the wastewater. After the reaction between the reagent and the wastewater is completed, the sewage pipe 13 is opened to discharge the impurities precipitated at the bottom of the box 1, and the drain pipe 12 is opened to discharge the treated water.

[0033] like Figure 2 , Figure 3 , Figure 6 , Figure 7 , Fig. 9 As shown, as a preferred embodiment of the present invention, the material dividing assembly 41 includes a plurality of groups of material dividing plates 411 fixedly installed in the inner cavity of the vertical cylinder 2 and distributed in parallel in the vertical direction, the material dividing plate 411 is a conical structure, the material dividing plate 411 is located below the end opening of the stirring tube 3, a material storage cavity 412 is formed between the material dividing plate 411 and the side wall of the vertical cylinder 2, and a plurality of groups of through holes 413 distributed in an annular shape are opened on the surface of the material dividing plate 411.

[0034] The medicine to be added is put into the feeding funnel 22 at one time, and the medicine moves downward in the inner cavity of the vertical cylinder 2 and falls on the surface of the uppermost dividing plate 411. The storage cavity 412 can store a certain amount of medicine, and the remaining excess medicine can continue to fall in the inner cavity of the vertical cylinder 2 through the through hole 413 and then fall on the surface of the dividing plate 411 below. This is repeated many times, and batches of medicine can be stored on the surface of the dividing plate 411 at different heights in the inner cavity of the vertical cylinder 2. During the feeding process, the motor 21 can drive the vertical cylinder 2 to rotate and accelerate the discharge of the medicine from the through hole 413.

[0035] After the medicine is added, the positioning part 422 controls the baffle plate 421 to move upward a certain distance in the inner cavity of the vertical cylinder 2 so that the guide hole 4211 is aligned with the opening at the end of the stirring tube 3. At this time, the motor 21 drives the vertical cylinder 2 to rotate, and the centrifugal force during rotation can transport the medicine on the surface of the dividing plate 411 to the inner cavity of the stirring tube 3.

[0036] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Fig.10 As shown, as a preferred embodiment of the present invention, the positioning portion 422 includes a top plate 4221 with multiple groups of baffles 421 extending from the top end to the top of the feed funnel 22 and fixedly installed, and the bottom wall of the top plate 4221 is rotatably installed with multiple groups of support rods 4222 inserted into the feed funnel 22, and the inner wall of the feed funnel 22 is provided with a support groove 4223 that cooperates with the support rods 4222.

[0037] Initially, multiple groups of support rods 4222 support and position the top plate 4221 in the feed hopper 22, and the top plate 4221 cooperates with the inner wall of the vertical tube 2 to support and position the baffle 421. At this time, the baffle 421 seals the opening at the end of the stirring tube 3. After the medicine is put into the feed hopper 22, the top plate 4221 is pulled upward in the feed hopper 22, and the support rods 4222 are inserted into the support grooves 4223. The support rods 4222 and the support grooves 4223 cooperate with each other to support and position the top plate 4221. At this time, the top plate 4221 pulls the baffle 421 to move upward a certain distance in the inner cavity of the vertical tube 2. At this time, the guide hole 4211 on the surface of the baffle 421 is aligned with the opening at the end of the stirring tube 3. At this time, the motor 21 drives the vertical tube 2 to rotate, and the centrifugal force during rotation can transport the medicine on the surface of the dividing plate 411 to the inner cavity of the stirring tube 3.

[0038] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.10As shown, as a preferred embodiment of the present invention, the rotating part 432 includes a gear ring 4321 fixedly installed on the surface of the sealing tube 431, and the side wall of the vertical cylinder 2 is slidably installed with a vertical rod 4322 located on the outside of the gear ring 4321 in the vertical direction, and the side wall of the vertical rod 4322 is fixedly installed with a rack 4323 meshing with the gear ring 4321, and the top ends of multiple groups of vertical rods 4322 extend to the outside of the box body 1 through the fixed plate 23 and are commonly fixedly installed with a control ring 4324, which is sleeved on the outside of the vertical cylinder 2, and a clamping piece 5 is provided on the surface of the control ring 4324.

[0039] The clamping member 5 fixes the position of the control ring 4324 on the outside of the vertical cylinder 2, and the control ring 4324 cooperates with the vertical rod 4322 to fix the position of the rack 4323 on the outside of the vertical cylinder 2. The rack 4323 meshes with the gear ring 4321 to drive the outside of the stirring tube 3 to fix the position of the sealing tube 431. Initially, the first discharge hole 4311 on the bottom wall of the stirring tube 3 and the second discharge hole 4312 on the surface of the sealing tube 431 are staggered. When the agent is transported to the inner cavity of the stirring tube 3, the agent can be stably placed in the inner cavity of the stirring tube 3. When wastewater needs to be treated, the clamping member 5 is fixed on the vertical cylinder 2 The position of the control ring 4324 is adjusted on the outside so that the control ring 4324 moves upward a certain distance on the outside of the vertical tube 2. The control ring 4324 pulls the vertical rod 4322 and the rack 4323 to move synchronously. When moving, the rack 4323 meshes with the gear ring 4321 to drive the sealing tube 431 to rotate on the outside of the stirring tube 3. The sealing tube 431 rotates to adjust the position of the second discharge hole 4312. After the second discharge hole 4312 coincides with the first discharge hole 4311, the medicine in the stirring tube 3 passes through the first discharge hole 4311 and the second discharge hole 4312 and can automatically fall into the inner cavity of the box body 1 to mix with the wastewater.

[0040] In the process of discharging the medicine in the stirring tube 3, the rotation amplitude of the sealing tube 431 can be adjusted through the meshing transmission of the rack 4323 and the ring gear 4321, and then the overlapping size of the first discharge hole 4311 and the second discharge hole 4312 can be adjusted, and then the discharge rate of the medicine can be adjusted, so that the discharge speed of the medicine and the rotation speed of the stirring tube 3 are adapted to each other, effectively improving the full reaction between the medicine and the wastewater.

[0041] like Figure 2 , Figure 4 , Fig.10 As shown, as a preferred embodiment of the present invention, the clamping member 5 includes a plurality of positioning screw holes 51 arranged in parallel along the vertical direction and opened on the side wall of the vertical tube 2, and the surface of the control ring 4324 is provided with positioning bolts 52 that cooperate with the positioning screw holes 51.

[0042] Initially, the positioning bolt 52 is installed on the surface of the control ring 4324 and inserted into the lowest positioning screw hole 51. At this time, the first discharge hole 4311 on the bottom wall of the stirring tube 3 and the second discharge hole 4312 on the surface of the sealing tube 431 are staggered. When the reagent in the stirring tube 3 needs to be discharged, the positioning bolt 52 is removed and the control ring 4324 is pulled upward on the surface of the vertical cylinder 2. After the control ring 4324 moves upward a certain distance, the positioning bolt 52 is installed on the surface of the control ring 4324 and inserted into the positioning screw hole 51 at the corresponding position. The position of the control ring 4324 can be fixed again. At this time, the second discharge hole 4312 coincides with the first discharge hole 4311.

[0043] like Fig. 9 , Fig.11 As shown, as a preferred embodiment of the present invention, the surface of the stirring tube 3 is provided with multiple groups of first adjustment holes 6 respectively located on both sides of the first discharge hole 4311, and the surface of the sealing tube 431 is provided with multiple groups of second adjustment holes 7 that cooperate with the first adjustment holes 6.

[0044] When the sealing tube 431 rotates so that the second discharge hole 4312 is aligned with the first discharge hole 4311, the agent can be discharged from the inner cavity of the stirring tube 3, and the wastewater in the inner cavity of the box body 1 can also flow into the inner cavity of the stirring tube 3. The first adjustment hole 6 and the second adjustment hole 7 on both sides cooperate with each other, which can effectively reduce the impact of the wastewater on the agent in the inner cavity of the stirring tube 3. During the rotation and stirring process of the stirring tube 3, the agent can be stably discharged from the stirring tube 3.

[0045] like Fig. 9 , Fig.11 As shown, as a preferred embodiment of the present invention, a sealing gasket 8 that cooperates with the second discharge hole 4312 is fixedly installed on the outer wall of the stirring tube 3.

[0046] The sealing gasket 8 can further improve the sealing effect between the sealing tube 431 and the stirring tube 3. When the agent is not discharged, the sealing gasket 8 seals the second discharge hole 4312, effectively preventing the waste water in the inner cavity of the box body 1 from flowing through the second discharge hole 4312 to the gap between the sealing tube 431 and the stirring tube 3.

[0047] The working principle of the present invention is as follows: initially, the baffle 421 seals the opening at the end of the stirring tube 3, and the first discharge hole 4311 on the bottom wall of the stirring tube 3 is staggered with the second discharge hole 4312 on the surface of the sealing tube 431. When in use, the wastewater to be treated is put into the inner cavity of the box body 1 through the water injection port 11, and the medicine to be added is put into the feeding funnel 22 at one time. The medicine moves downward in the inner cavity of the vertical cylinder 2 and falls on the surface of the uppermost dividing plate 411. The storage cavity 412 can store a certain amount of medicine, and the remaining excess medicine can continue to fall in the inner cavity of the vertical cylinder 2 through the through hole 413 and then fall to the surface of the dividing plate 411 below. This is repeated many times, and batches of medicine can be stored on the surface of the dividing plate 411 at different heights in the inner cavity of the vertical cylinder 2. During the unloading process, the motor 21 can drive the vertical cylinder 2 to rotate and accelerate the discharge of the medicine from the through hole 413.

[0048] After the medicine is put into the feed hopper 22, the top plate 4221 is pulled upward to insert the support rod 4222 into the support groove 4223. The support rod 4222 and the support groove 4223 cooperate with each other to support and position the top plate 4221. At this time, the top plate 4221 pulls the baffle plate 421 to move upward for a certain distance in the inner cavity of the vertical cylinder 2. At this time, the guide hole 4211 on the surface of the baffle plate 421 is aligned with the opening at the end of the stirring tube 3. At this time, the motor 21 drives the vertical cylinder 2 to rotate, and the medicine on the surface of the dividing plate 411 can be transported to the inner cavity of the stirring tube 3 through the centrifugal force during rotation.

[0049] When it is necessary to treat the wastewater, the position of the control ring 4324 is adjusted on the outside of the vertical cylinder 2, so that the control ring 4324 moves upward a certain distance on the outside of the vertical cylinder 2, and the control ring 4324 pulls the vertical rod 4322 and the rack 4323 to move synchronously. When moving, the rack 4323 meshes with the gear ring 4321 to drive the sealing tube 431 to rotate on the outside of the stirring tube 3. The sealing tube 431 rotates to adjust the position of the second discharge hole 4312. After the second discharge hole 4312 coincides with the first discharge hole 4311, the medicine in the stirring tube 3 passes through the first discharge hole 4311 and the second discharge hole 4312 and can automatically fall into the inner cavity of the box 1 to mix with the wastewater. In the process of discharging the medicine in the stirring tube 3, the rotation amplitude of the sealing tube 431 can be adjusted through the meshing transmission of the rack 4323 and the ring gear 4321, and then the overlapping size of the first discharge hole 4311 and the second discharge hole 4312 can be adjusted, and then the discharge rate of the medicine can be adjusted, so that the discharge speed of the medicine and the rotation speed of the stirring tube 3 are adapted to each other, effectively improving the full reaction between the medicine and the wastewater.

[0050] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
