[0018] 2. The rotating part can rotate in the process of conveying the liquid medicine. The centrifugal force generated by the rotation of the rotating part can further accelerate the speed of the liquid medicine spraying out of the rotating part, and impact the flocculants that may exist on the upper baffle due to backflow. The rotation of the rotating part can form the liquid medicine into a uniform spray shape, so that the amount of liquid medicine entering the multiple axially arranged diversion pipes can be as balanced as possible;

[0019] 3. The rotation of the stirring end in the treatment tank can synchronously drive the conversion cylinder to rotate, so the lower baffle, upper baffle and the outer diverter tube will rotate synchronously. The centrifugal force brought by the rotation further helps the liquid medicine to be thrown out of the diverter tube, and at the same time further reduces the possible blockage on the upper baffle and the diverter tube;

[0020] 4. The rotation of the conversion cylinder drives the diversion pipe on it to rotate accordingly, which can be synchronized with the stirring end in the treatment tank to stir the wastewater. At the same time, the centrifugal force generated by the rotation of the conversion cylinder will further ensure the balance of the amount of liquid medicine in each diversion pipe, and further improve the mixing degree between the liquid medicine and the wastewater.

[0021] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0042] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] like Figure 1-Figure 4 As shown, according to a microbial wastewater treatment dosing device of an embodiment of the present application, it is located in a microbial wastewater treatment system. The microbial wastewater treatment system controls the operation of electrical components in the entire system through an industrial control cabinet 14, and uses a desalted water pipe and a drug delivery water pipe to respectively transport desalted water and drug solution to the interior of a treatment tank 1, and further treats the wastewater in the treatment tank 1. Impurities such as flocculants generated during the treatment process are discharged to the floor drain, and the treated wastewater is transported to the subsequent process through a drainage component 15 for continued operation. Specifically, the entire microbial wastewater treatment system is a prior art, and the specific treatment principles and detailed processes are not further described here.

[0044] In a specific embodiment of the present application, a liquid supply end 11 is disposed at the top of the treatment tank 1 , a water outlet end 12 is disposed at the bottom, and a stirring assembly 13 is disposed inside. The liquid supply end 11 specifically includes a water inlet pipe 111 and a medicine inlet pipe 112 .

[0045] Specifically, the water inlet pipe 111 is connected to the desalted water pipe, the drug inlet pipe 112 is connected to the drug delivery water pipe, and the water outlet end 12 is connected to the floor drain and the drainage component 15 respectively.

[0046] The stirring assembly 13 includes a stirring motor 131 fixedly connected to the top of the processing tank 1. The output end of the stirring motor 131 is keyed to a stirring shaft 132, and a stirring blade 133 is fixedly connected to the stirring shaft 132. It can be understood that the liquid in the processing tank 1 can be stirred by rotating the stirring blade 133.

[0047] Embodiment 1, as Figure 5 As shown, a microbial wastewater treatment dosing device according to an embodiment of the present application further includes a drug discharging mechanism 2, which is disposed at the inner bottom of the treatment tank 1 and communicated with a pipeline for conveying drug solution so as to convey the drug solution to the inner bottom of the treatment tank 1.

[0048] like Figure 5-Figure 10As shown, the medicine discharging mechanism 2 includes a medicine inlet barrel 21 coaxially fixed to the bottom of the processing tank 1, and the interior of the medicine inlet barrel 21 is divided into two upper and lower layers that are not connected. The upper layer is connected to the pipeline for conveying the medicine liquid, and the lower layer is connected to the outlet of the processing tank 1. Specifically, a partition 211 is fixed to the interior of the medicine inlet barrel 21, and the partition 211 divides the interior of the medicine inlet barrel 21 into two upper and lower layers that are not connected. A medicine inlet 212 that is compatible with the pipeline for conveying the medicine liquid is provided on the side wall of the upper layer, and a plurality of discharge ports 213 are evenly arranged on the bottom circumference of the side wall of the lower layer. It can be understood that the medicine liquid can and can only enter the upper layer of the medicine barrel 21, and the waste water in the processing tank 1 can enter the water outlet 12 through the discharge port 213.

[0049] Among them, the upper end of the medicine inlet barrel 21 is coaxially rotatably connected with a conversion barrel 22, the conversion barrel 22 is coaxially fixed to the stirring end in the processing tank 1, specifically, coaxially fixed to the stirring shaft 132, and a lower baffle 23 and an upper baffle 24 are coaxially arranged in the conversion barrel 22, the lower baffle 23 and the upper baffle 24 change the direction of the medicine liquid flow channel, specifically, the upper end of the medicine inlet barrel 21 is coaxially sealed and connected with a swivel 214, and the swivel 214 is coaxially sealed and rotatably connected to the conversion barrel 22, therefore, it can be seen that the conversion barrel 22 can rotate on the medicine inlet barrel 21.

[0050] Furthermore, a plurality of arc-shaped baffles 231 are fixedly connected to the bottom side of the lower baffle 23, and the plurality of arc-shaped baffles 231 are evenly arranged circumferentially, and the plurality of arc-shaped baffles 231 form an annular structure, the inner diameter of the annular structure is not less than the diameter of the connecting point between the conversion cylinder 22 and the medicine inlet cylinder 21, and the outer diameter of the annular structure is not greater than the outer diameter of the lower baffle 23, and the outer diameter of the lower baffle 23 is smaller than the inner diameter of the conversion cylinder 22. It can be seen that after the medicine enters the medicine inlet cylinder 21, it will pass through the rotating ring 214 and then enter the bottom of the lower baffle 23, and then flow to the top of the lower baffle 23 through the arc-shaped channel formed between the plurality of arc-shaped baffles 231.

[0051] It should be noted that the plurality of arc-shaped baffles 231 are fixedly connected to the inner bottom of the conversion cylinder 22 to form an arc-shaped channel evenly arranged circumferentially between the conversion cylinder 22 and the lower baffle 23, which guides the liquid medicine and evenly distributes the liquid medicine.

[0052] The upper end surface of the lower baffle 23 is coaxially fixed with a lower partition 232, and a plurality of lower channels 233 are evenly arranged circumferentially on the bottom of the lower partition 232. A lower baffle ring 234 is coaxially fixed on the inner wall of the lower partition 232. It can be seen that the medicine can enter the interior of the lower partition 232 through the lower channel 233, and flow upward axially along the lower partition 232 under the action of pressure.

[0053] Furthermore, the upper baffle 24 is fixedly connected to the conversion cylinder 22, and the upper baffle 24 is fixedly connected to the lower partition 232. The upper end face of the upper baffle 24 is coaxially fixed with the upper partition 241. The upper partition 241 and the lower partition 232 are connected and have the same inner and outer diameters. A plurality of upper channels 242 are evenly arranged axially on the side wall of the upper partition 241. An upper retaining ring 243 is arranged on the upper side of the upper channel 242. The upper retaining ring 243 is coaxially fixed to the upper partition 241. The radial cross-section of the upper retaining ring 243 is stepped, and a gap is formed between the upper retaining ring 243 and the inner wall of the upper partition 241. It can be seen that the medicine can enter the upper partition 241 from the lower partition 232, and finally flow out from the upper channel 242 and surge to the top of the upper baffle 24.

[0054] like Figure 6-Figure 10 As shown, a rotating member 25 is coaxially arranged inside the lower baffle 23 and the upper baffle 24. The rotating member 25 is axially displaced inside the lower baffle 23 and the upper baffle 24. The rotating member 25 rotates under the action of the flow of the liquid medicine. The side walls of the rotating member 25 are sealed with the inner walls of the lower baffle 23 and the upper baffle 24 respectively. The axial displacement of the rotating member 25 causes the liquid flow channel between the lower baffle 23 and the upper baffle 24 to form an on-off phenomenon.

[0055] It should be noted that, in the specific embodiment of the present application, the rotating member 25 is located between the lower retaining ring 234 and the upper retaining ring 243 , that is, the axial displacement stroke of the rotating member 25 is limited by the lower retaining ring 234 and the upper retaining ring 243 .

[0056] Specifically, the rotating member 25 includes a coaxially arranged base 251 and a top pressure block 252, and a special-shaped cavity 253 is arranged between the base 251 and the top pressure block 252. The special-shaped cavity 253 is arranged in a ring shape, and the special-shaped cavity 253 is arranged in an arc shape in the radial direction. The bottom opening of the special-shaped cavity 253 is larger than its top opening, and a plurality of arc-shaped partitions 254 are evenly arranged in the circumferential direction of the special-shaped cavity 253. The plurality of arc-shaped partitions 254 divide the special-shaped cavity 253 into a plurality of special-shaped channels of the same size, and an upper slide groove 255 is coaxially arranged on the upper end face of the top pressure block 252, and an upwardly protruding outer eaves is arranged on the circumferential side of the upper end face of the top pressure block 252. It can be seen that when the medicine enters the upper partition 241 from the lower partition 232, it will flow from the bottom end of the special-shaped cavity 253 to the upper end through the special-shaped channel.

[0057] It should be noted that when the rotating member 25 undergoes an upward axial displacement and abuts against the upper retaining ring 243 , a connection is formed between the upper end of the special-shaped cavity 253 and the upper channel 242 , and at this time the medicine can flow out of the special-shaped cavity 253 and flow to the outside of the upper partition 241 .

[0058] It can be further understood that the irregular channel formed in the irregular cavity 253 with a large bottom and a small top will also have a large bottom and a small top shape, and under the action of the arc-shaped partition 254, the multiple irregular channels will be angularly deflected in the axial direction. Therefore, when the medicine liquid flows out of the rotating part 25, it will be impacted by the fluid and cause the rotating part 25 to rotate.

[0059] It should be noted that the outer edge of the upper end of the top pressure block 252 is plugged into the gap formed between the upper baffle ring 243 and the upper partition 241. The height of the outer edge of the upper end of the top pressure block 252 is set so that when the bottom end of the rotating member 25 abuts against the lower baffle ring 234, the outer edge will seal the upper channel 242 to prevent wastewater carrying flocculants and other debris from flowing back into the upper partition 241 when no medicine is supplied.

[0060] The upper end of the rotating member 25 is coaxially provided with an elastic plate 26, and the elastic plate 26 is axially elastically displaced in the upper baffle plate 24. Specifically, the elastic plate 26 and the upper end surface of the top pressure block 252 are rotatably matched, and the elastic plate 26 and the inner wall of the upper outer edge of the top pressure block 252 are rotatably matched. The upper end surface of the elastic plate 26 is evenly fixed with a plurality of guide rods 261 in the circumferential direction, and the plurality of guide rods 261 are slidably inserted into the upper baffle ring 243. It should be noted here that the guide rods 261 never separate from the upper baffle ring 243 to ensure that the elastic plate 26 can and can only undergo axial displacement in the upper spacer 241; the lower end surface of the elastic plate 26 is coaxially provided with a sliding groove 262, and a ball 263 is rollingly arranged between the sliding groove 262 and the upper groove 255. It can be understood here that the design of the ball 263 reduces the friction between the rotating member 25 and the elastic plate 26, making it easier for the rotating member 25 to rotate; the elastic plate A positioning rod 264 is slidably inserted at the axis of 26, one end of the positioning rod 264 is fixedly connected to the inner top of the conversion cylinder 22, and the other end of the positioning rod 264 is fixedly connected to the lower baffle plate 23. A first spring 265 is sleeved on the positioning rod 264, one end of the first spring 265 abuts against the inner top of the conversion cylinder 22, and the other end of the first spring 265 abuts against the upper end surface of the elastic plate 26. It can be seen that when the medicine is transported into the processing tank 1, the pressure will force the rotating member 25 to rise until the special-shaped cavity 253 thereon and the upper channel 242 are connected. At this time, the medicine is ejected from the rotating member 25 and drives the rotating member 25 to rotate. At the same time, the first spring 265 is squeezed due to the rising of the rotating member 25. Therefore, when the medicine stops being transported, the elastic force of the first spring 265 will force the rotating member 25 to fall until it abuts against the lower baffle ring 234.

[0061] Furthermore, a plurality of shunt pipes 27 are evenly connected circumferentially on the side wall of the conversion cylinder 22, and a plurality of liquid outlet holes are evenly distributed on the side wall of the shunt pipe 27. Specifically, the shunt pipe 27 is arranged in a cylindrical shape with a closed outer end, and the plurality of liquid outlet holes evenly arranged on the outer wall of the shunt pipe 27 are medicine discharge holes 273. It can be understood that the medicine enters into the plurality of shunt pipes 27 respectively from the upper end of the upper baffle 24, and finally enters into the interior of the treatment tank 1 from the medicine discharge holes 273 to mix with the wastewater.

[0062] The following describes the use process of a microbial wastewater treatment dosing device according to an embodiment of the present application with reference to the accompanying drawings:

[0063] When delivering the medicine liquid, the medicine liquid enters the upper layer of the medicine inlet barrel 21, and flows axially to the bottom side of the lower baffle plate 23, and radially diffuses by the arc channel formed by multiple circumferentially evenly distributed arc baffles 231, and returns from the circumferential side of the lower baffle plate 23 to the top of the lower baffle plate 23, and enters the interior of the lower partition 232 from the lower channel 233. The medicine liquid enters from the bottom end of the special-shaped cavity 253 under the action of pressure. At this time, the rotating member 25 abuts against the lower baffle ring 234 under the elastic force of the first spring 265, so the special-shaped cavity 253 and the upper channel 242 are not connected, so the medicine liquid will not flow out from the circumferential side of the rotating member 25. Under the action of the medicine liquid pressure, the rotating member 25 will move upward and squeeze the first spring 265 until the special-shaped cavity 253 is filled. The upper channel 242 is connected to the special-shaped cavity 253. At this time, the medicine liquid can be sprayed out from the upper end of the special-shaped cavity 253 (i.e., the circumferential side of the rotating member 25), and enter the upper baffle 24 (the outer side of the upper partition 241) through the upper channel 242. When the medicine liquid is sprayed out from the special-shaped cavity 253, firstly, due to the design of the shape of the special-shaped channel in the special-shaped cavity 253, the rotating member 25 will be exerted with a rotational force, forcing the rotating member 25 to rotate, and the special-shaped channel with a large bottom and a small top will further accelerate the injection speed of the medicine liquid, and the convex eaves on the top pressure block 252 will keep the upper channel 242 blocked when the special-shaped cavity 253 and the upper channel 242 are not connected. Therefore, when the medicine is not supplied, the waste water in the treatment tank 1 and the flocculants and other debris therein can only be reflected. It is poured to the outside of the upper partition 241, so when the medicine liquid is sprayed out from the special-shaped cavity 253, the accelerated medicine liquid can also impact the debris on the outside of the upper partition 241 to break through the possible blockage. When supplying medicine, it is conceivable that the stirring motor 131 will drive the stirring shaft 132 to drive the stirring blade 133 to rotate, and stir the wastewater in the treatment tank 1 to improve the effect of wastewater treatment. When the stirring shaft 132 rotates, it will drive the coaxially fixed conversion cylinder 22 to rotate synchronously and in the same direction. Therefore, the debris on the outside of the upper partition 241 will be affected by the centrifugal force brought by the rotation. Under the impact of the medicine liquid and the action of the centrifugal force, it will rush into the diversion pipe 27 together with the medicine liquid, because a plurality of medicine discharge holes are evenly arranged on the side wall of the diversion pipe 27. 273, the solid medicine liquid will carry the possible impurities and be sprayed into the wastewater in the treatment tank 1 from the medicine discharge hole 273. At the same time, because the size of the medicine discharge hole 273 is significantly smaller than the volume of the shunt pipe 27, and the volume of the shunt pipe 27 is significantly smaller than the space outside the upper partition cylinder 241 above the upper baffle plate 24, the impact force of the medicine liquid on the medicine discharge hole 273 will be significantly enhanced. This design will make the medicine discharge hole 273, which may be blocked by flocculants and other impurities, be impacted by the medicine liquid, further reducing the possible blockage of the medicine discharge mechanism 2. At the same time, the shunt pipe 27 rotates synchronously with the conversion cylinder 22, and the medicine liquid is sprayed from the peripheral side of the shunt pipe 27, which will further enhance the mixing degree between the medicine liquid and the wastewater.On the contrary, when the liquid medicine is not needed, the elastic force of the first spring 265 will force the rotating member 25 to move downward until it abuts against the lower retaining ring 234. At this time, the convex edge of the top pressure block 252 will block the upper channel 242, preventing the waste water and debris in the treatment tank 1 from flowing back into the upper partition 241 under the action of pressure, reducing the blockage of the entire medicine dispensing mechanism 2 to a certain extent, and ensuring the normal delivery of the liquid medicine in the later stage.

[0064] In the related art, in this type of microbial wastewater treatment dosing equipment, when the drug supply is stopped, only the upper channel 242 is blocked in the conversion cylinder 22, and the wastewater and debris in the treatment tank 1 can enter the outside of the upper partition cylinder 241 from the drug discharge hole 273, causing blockage at the drug discharge hole 273 and the outside of the upper partition cylinder 241. Once too much debris enters, the diverter pipe 27 may also be blocked, affecting the efficiency of subsequent drug delivery to the wastewater.

[0065] Embodiment 2, according to some embodiments of the present application, such as Figure 11-Figure 15 As shown, the shunt tube 27 includes a coaxially arranged fixed end 271 and a rotating end 272 , the fixed end 271 is fixedly connected to the conversion cylinder 22 , and the rotating end 272 is coaxially rotatably connected to the fixed end 271 , thereby it can be known that the rotating end 272 can rotate on the fixed end 271 .

[0066] It should be noted that the medicine discharge through hole 273 is located at the rotating end 272 .

[0067] Furthermore, a blocking mechanism 3 is coaxially arranged in the shunt pipe 27, and the blocking mechanism 3 includes: a positioning ring 31, a positioning shaft 32, a positioning cylinder 33, a plurality of intermediate cylinders 34, a plurality of blocking cylinders 35 and a limiting shaft 36, wherein the positioning ring 31 is coaxially fixed to the inside of the fixed end 271; the positioning shaft 32 is coaxially slidably inserted in the positioning ring 31; the positioning cylinder 33 is coaxially fixed to the positioning shaft 32, and the positioning cylinder 33 is located on the side of the positioning ring 31 facing the rotating end 272; a plurality of intermediate cylinders 34 are sleeved on the positioning shaft 32, and among the plurality of intermediate cylinders 34, except for the intermediate cylinder 34 on the side of the blocking end close to the rotating end 272, which is fixed to the positioning shaft 32, the other intermediate cylinders 34 The rotating cylinders 34 are not in contact with the positioning shaft 32, and multiple rotating cylinders 34 are evenly distributed axially in the rotating end 272. The multiple rotating cylinders 34 and the rotating end 272 can and can only be axially sealed and slidably connected. It can be understood here that the rotating cylinder 34 cannot rotate in the rotating end 272; multiple blocking cylinders 35 are sleeved on the positioning shaft 32 and do not contact the positioning shaft 32, multiple blocking cylinders 35 and multiple rotating cylinders 34 are arranged at intervals, and the blocking cylinders 35 are coaxially fixed to the rotating cylinder 34, and the multiple blocking cylinders 35 and the rotating end 272 can and can only be axially sealed and slidably connected; the limiting shaft 36 is coaxially fixed to the blocking end of the rotating end 272.

[0068] It should be noted that if Fig.13 As shown, a plurality of through holes 311 are evenly arranged circumferentially on the positioning ring 31 , and the inner diameter of the annular structure formed by the plurality of through holes 311 is not less than the outer diameter of the positioning shaft 32 .

[0069] Specifically, one end of the positioning shaft 32 located in the conversion cylinder 22 is coaxially fixed with a positioning plate 321, and a second spring 322 is sleeved on the positioning shaft 32. One end of the second spring 322 abuts against the positioning ring 31, and the other end of the second spring 322 abuts against the positioning plate 321. It can be seen that the second spring 322 will enable the positioning shaft 32 to undergo axial elastic displacement in the diverter tube 27.

[0070] Furthermore, the structure of one end of the positioning cylinder 33 facing the positioning ring 31 is similar to that of the positioning ring 31 (not shown in the figure), and a plurality of through holes are also arranged on the end face. The positioning cylinder 33 and the adjacent rotating cylinder 34 are coaxially fixedly connected. It can be seen that an integral structure will be formed between the positioning shaft 32, the positioning cylinder 33, the plurality of rotating cylinders 34 and the plurality of blocking cylinders 35, that is, their displacement movements are consistent; axial cavities of the same diameter are arranged at the axis center of the positioning cylinder 33 and the axis center of the rotating cylinder 34, and the two axial cavities are connected. It can be understood that the medicine will enter the interior of the rotating end 272 through the positioning ring 31, and then can and can only pass through the end of the positioning cylinder 33, enter the axial cavity inside the positioning cylinder 33, and enter the axial cavity inside the rotating cylinder 34.

[0071] Further, such as Fig.15 As shown, the rotating cylinder 34 farthest from the positioning ring 31 among the multiple rotating cylinders 34 has a closed end facing the limiting shaft 36. It can be understood that when all the rotating cylinders 34 follow the axial displacement of the positioning shaft 32, the blocked end of the rotating cylinder 34 will touch the limiting shaft 36 to limit the displacement stroke of the positioning shaft 32.

[0072] Furthermore, the axial cavity at the axis center of the rotating cylinder 34 is a central cavity 341, the diameter of the central cavity 341 is larger than the outer diameter of the positioning shaft 32, and the axis center of the blocking cylinder 35 is provided with an axial cavity 351 with the same diameter as the central cavity 341. It can be seen that the medicine will flow from the positioning ring 31 along the axial direction of the positioning shaft 32 to the rotating cylinder 34 close to the limiting shaft 36.

[0073] Furthermore, a plurality of side water outlet channels 342 are evenly arranged circumferentially on the rotating cylinder 34 , the plurality of side water outlet channels 342 are connected to the central cavity 341 , and the plurality of side water outlet channels 342 penetrate the side wall of the rotating cylinder 34 and correspond one-to-one to the plurality of medicine discharge holes 273 .

[0074] It should be noted that, in the specific embodiment of the present application, when the positioning shaft 32 is displaced to the limit direction of the limit shaft 36, the side water outlet channel 342 is connected to the drug discharge through hole 273, and when the positioning shaft 32 is displaced away from the limit shaft 36, the side water outlet channel 342 and the drug discharge through hole 273 are misaligned, and the sealing tube 35 blocks the drug discharge through hole 273 at this time.

[0075] Therefore, during specific use, when the medicine is transported to the inside of the treatment tank 1, the medicine flows out from the upper partition tube 241 and enters each shunt tube 27. In the initial state, the positioning shaft 32 is forced to move toward the axis of the conversion tube 22 by the elastic force of the second spring 322. At this time, the positioning shaft 32 drives the positioning tube 33, the transfer tube 34, and the blocking tube 35 to move synchronously, so that the side water outlet channel 342 on each transfer tube 34 is misaligned with the corresponding medicine discharge through hole 273, and the blocking tube 35 forms a blocking state. After passing through the through hole 311 on the positioning ring 31, the medicine enters from the end of the positioning shaft 32, and along the axial direction of the positioning shaft 32, through the central cavity 341 and the axial cavity 351, it is filled in all the transfer tubes 34. Under the pressure of the medicine, the positioning shaft 32 is forced to form an overall 32, the positioning cylinder 33, the plurality of transfer cylinders 34 and the plurality of blocking cylinders 35 are synchronously axially displaced, so that the blocking cylinder 35 close to one end of the limiting shaft 36 is sleeved on the limiting shaft 36, and the blocking end of the transfer cylinder 34 adjacent to the blocking cylinder 35 is abutted against the limiting shaft 36. At this time, the positioning shaft 32, the positioning cylinder 33, the plurality of transfer cylinders 34 and the plurality of blocking cylinders 35 as a whole stop displacement. At this time, the side water outlet channels 342 on each transfer cylinder 34 are connected to the corresponding drug discharge holes 273, and the drug liquid is discharged from the drug discharge holes 273 into the wastewater in the treatment tank 1 through the side water outlet channels 342. This design will ensure that, when no drug is supplied, the wastewater in the treatment tank 1 and the debris therein will not be able to pass through the drug discharge holes 273 to enter the interior of the diverter pipe 27 at all, thereby fundamentally eliminating the phenomenon of blockage in the drug discharge mechanism 2.

[0076] In the related art, in this microbial wastewater treatment dosing equipment, when the drug supply is stopped, the drug discharge hole 273 is only blocked by the existence of the sealing tube 35 inside, so that wastewater and debris will not pass through the drug discharge hole 273 and enter the inside of the diversion pipe 27. However, the drug discharge hole 273 itself will inevitably be disturbed by debris. Once it is out of use for a long time and not cleaned thoroughly, it will inevitably cause the debris in the drug discharge hole 273 to dry up and cause blockage. In the subsequent drug supply process, it is difficult for the drug liquid to clear the blockage formed in this situation. Once there are many blockages caused by this situation, it will affect the normal transportation of the drug liquid.

[0077] Embodiment 3, according to some embodiments of the present application, such as Fig.16 and Fig.17 As shown, a plurality of spiral sheets 4 are coaxially fixedly sleeved on the positioning shaft 32 , and the plurality of spiral sheets 4 are evenly arranged in the circumferential direction of the positioning shaft 32 ; the side water outlet channel 342 is arranged in an arc shape in the radial direction of the rotating cylinder 34 .

[0078] One end of the spiral piece 4 abuts against the positioning cylinder 33 , and the other end of the spiral piece 4 abuts against the rotating cylinder 34 close to the limiting shaft 36 .

[0079] Specifically, the outer diameter of the spiral sheet 4 is not greater than the diameter of the central cavity 341 .

[0080] It can be understood that the existence of the spiral sheet 4 will form a spiral channel between the connected central cavity 341 and the axial cavity 351 .

[0081] It should be noted here that the positioning shaft 32 is movably connected to the positioning ring 31 .

[0082] Therefore, it can be understood that when the medicine is being transported, when the medicine flows in the connected central cavity 341 and the axial cavity 351, it will be guided by the spiral channel formed by the spiral blade 4, so that the medicine forms a spiral flow channel. In this process, the positioning shaft 32, the positioning cylinder 33, the multiple rotating cylinders 34 and the multiple blocking cylinders 35 that form the whole will have a tendency to rotate, and the side water outlet channel 342 is arranged in an arc shape in the radial direction of the rotating cylinder 34, which will further intensify the rotational potential energy of the positioning shaft 32, the positioning cylinder 33, the multiple rotating cylinders 34 and the multiple blocking cylinders 35 that form the whole when the medicine passes through the side water outlet channel 342, and the rotating end 272 is coaxially rotated and connected to the fixed end 271, so it will The positioning shaft 32, the positioning cylinder 33, the multiple transfer cylinders 34, the multiple blocking cylinders 35 and the rotating end 272 are caused to rotate. In this way, when in use, the rotating end 272 will rotate while following the rotation of the conversion cylinder 22. During this process, the medicine is discharged from the medicine discharge hole 273 into the wastewater, which will enhance the mixing ability. At the same time, the rotating end 272 rotates, and the medicine discharge hole 273 thereon will be impacted by the wastewater from multiple angles from the outside. The pressure of the medicine inside and the impact from the outside will enhance the internal and external impact of the medicine on the blockage caused by the drying of debris in the medicine discharge hole 273 due to long-term disuse and incomplete cleaning, which will help to clear the blockage in the medicine discharge hole 273 and ensure the supply of medicine in the entire treatment tank 1.

[0083] It should be noted that the specific models and specifications of the stirring motor 131, stirring shaft 132, stirring blades 133, industrial control cabinet 14, drainage assembly 15, first spring 265 and second spring 322 need to be selected and determined according to the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0084] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
