[0002] In order to remove harmful substances, suspended matter, pathogens and other substances contained in domestic sewage, industrial sewage or other wastewater, it is usually necessary to precipitate the sewage through a sedimentation tank system. At present, the reactor of the sedimentation tank system mainly adopts a continuous feeding method. After the materials and reagents enter the reactor, they immediately flow out of the reactor. It is difficult to ensure that the materials and reagents fully react before the materials flow out of the reactor, resulting in a low utilization rate of the reagents in the reactor in the prior art. Utility Model Content

[0008] In the first state, the feed portion is open and the discharge portion is closed; in the second state, the feed portion and the discharge portion are closed.

[0009] By adopting the above technical solution, multiple feeding reactors are arranged, each of which is provided with a feeding part and a discharging part. In the first state, the feeding part is opened and the discharging part is closed, and the feeding reactor can be fed.

[0013] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a feeding reaction device, wherein the feeding part comprises a feeding pipe, and the feeding pipe intersects with the projection of the first part in the first direction.

[0016] By adopting the above technical solution, when the material enters the interior of the feeding reactor tangentially along the feed pipe, the stirring part will cause the existing material in the feeding reactor to rotate along the second direction, and the new material entering the feeding reactor will collide with the existing material in the feeding reactor, thereby achieving a better mixing effect.

[0017] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a feeding reaction device, wherein the second part is conical.

[0018] By adopting the above technical solution, the conical design can facilitate the sedimentation of impurities such as sludge in the material in the second part, thereby improving the filtering effect.

[0034] After the set time, the last feeding reactor switches to the second state.

[0035] By adopting the above technical scheme, each feeding reactor can switch between the first state and the second state. When one of the N feeding reactors is in the first state, the material can be added to the feeding reactor. After the feeding is completed after the set time, one of the remaining N-1 unfed feeding reactors switches to the first state for feeding. The feeding reactor after feeding and the remaining N-2 unfed feeding reactors are switched to the second state. At this time, the feeding reactor after feeding can ensure that the material and the agent fully react to improve the utilization rate of the agent. In this way, by performing the aforementioned steps until the last feeding reactor in the unfed feeding reactor is in the first state, in this scheme, by controlling multiple feeding reactors to switch between the first state and the second state, it can ensure that the material and the agent fully react to improve the utilization rate of the agent, and can also ensure a high working efficiency.

[0040] After the set time, the Nth feed reactor is switched to the first state.

[0041] By adopting the above technical scheme, when the last feeding reactor is switched to the second state, the discharge part of the first feeding reactor is opened, and the remaining N-1 feeding reactors after feeding are in the second state. That is to say, this scheme makes full use of the feeding time of other feeding reactors to react the materials fed in advance. When the last feeding reactor is switched to the second state, the first feeding reactor has completed the reaction and can choose to start discharging. After the set time, the first feeding reactor has completed the discharging, and the first feeding reactor can be selected to switch to the first state to facilitate the addition of new materials. In this way, uninterrupted continuous feeding can be achieved, further improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

It can be understood that the present application does not limit the number of the first through holes 211 and the second through holes 311, for example, it can also be 1, 2, 4, 5, 6, etc.

[0056] In some embodiments, see Figure 1 , Figure 3 The feeding reaction equipment 10 includes a plurality of feeding reactors 11, a plurality of feeding parts 12 and a plurality of discharging parts 13. The plurality of feeding reactors 11 are arranged in series, and each feeding reactor 11 can be switched between a first state and a second state. Each feeding part 12 is arranged corresponding to each feeding reactor 11, and each discharging part 13 is arranged corresponding to each feeding reactor 11. Each discharging part 13 is arranged at intervals from each feeding part 12 in each feeding reactor 11 for connecting with the coagulation reactor 20. In the first state, the feeding part 12 is open and the discharging part 13 is closed; in the second state, the feeding part 12 and the discharging part 13 are closed.

[0057] By adopting the above technical solution, a plurality of feeding reactors 11 are provided, and a feeding part 12 and a discharging part 13 are provided on each feeding reactor 11. In the first state, the feeding part 12 is opened, the discharging part 13 is closed, and the feeding reactor 11 can be fed.

[0058] In some embodiments, see Figure 1 , Figure 3 The feeding reaction device 10 includes a plurality of first dosing parts 14, each of which is arranged corresponding to each feeding reactor 11. In the first state, the first dosing part 14 is opened; in the second state, the first dosing part 14 is closed.

Exemplarily, the feeding reaction device 10 includes N feeding reactors 11, and correspondingly, the feeding reaction device 10 includes N feeding parts 12, N discharging parts 13 and N first dosing parts 14. Among them, N can be 2, 3, 4, 5, 6, 7, 8, 9, 10 and the like, and this application does not limit this. In the first state, the first dosing part 14 and the feeding part 12 are opened, and the discharging part 13 is closed, so as to add medicine and feed into the feeding reactor 11 at the same time, thereby improving work efficiency.

[0059] In some embodiments, see Figure 1 , Figure 2 The coagulation reactor 20 includes a second dosing unit 22 for introducing a coagulant into the coagulation reactor 20. Figure 1 The flocculation reactor 30 includes a third dosing section 32 for introducing a flocculant into the flocculation reactor 30. The flocculant is then introduced into the flocculation reactor 30. Figure 1 The direction indicated by the arrow d flows into the flocculation reactor 30, and can further react with the mixed slurry with chemical sludge, so that the destabilized chemical sludge is condensed into larger flocs, which is conducive to precipitation. Exemplarily, the coagulant includes PAC (Polyaluminum chloride, polyaluminum chloride), and the flocculant includes PAM (Polyacrylamide, Polyacrylic amide, polyacrylamide). The present application does not limit the types of coagulants and flocculants, for example, the coagulant can also be PFS (Polyferric sulfate, polyferric sulfate) and the like.

[0060] In some embodiments, see Figure 1 , Figure 3 , Figure 4, the feeding reactor 11 includes a first part 111 and a second part 112, the feeding part 12 is arranged on the side of the first part 111, the first dosing part 14 is arranged on the top surface of the first part 111, and the discharging part 13 is arranged in the second part 112. In some embodiments, the feeding part 12 includes a feeding pipe 121, and the feeding pipe 121 intersects with the projection of the first part 111 in the first direction X. Exemplarily, the first part 111 is cylindrical, and the feeding pipe 121 is tangent to the first part 111. It can be understood that the present application does not limit the shape of the first part 111, for example, it can also be a cubic shape. In some embodiments, the first dosing part 14 includes a first dosing pipe 141, the second dosing part 22 includes a second dosing pipe 221, the third dosing part 32 includes a third dosing pipe 321, and the discharging part 13 includes a discharging pipe 131, and the discharging pipe 131 is used to connect with the coagulation reactor 20.

[0061] In some embodiments, the feeding reaction device 10 further includes a plurality of first control valves (not shown in the figure), each of which is arranged corresponding to each feeding reactor 11. Exemplarily, each first control valve is arranged at the feeding pipe 121 of each feeding reactor 11, and is used to control the opening and closing of the feeding part 12. In some embodiments, the feeding reaction device 10 further includes a plurality of second control valves (not shown in the figure), each of which is arranged corresponding to each feeding reactor 11. Exemplarily, each second control valve is arranged at the first dosing pipe 141 of each feeding reactor 11, and is used to control the opening and closing of the first dosing part 14.

[0062] In some embodiments, the feeding reaction device 10 further includes a plurality of water pumps (not shown in the figure), each of which is arranged corresponding to each feeding reactor 11. Exemplarily, the water pump is arranged in the second part 112, and is used to assist in discharging the material in the feeding reactor 11 into the coagulation reactor 20, so as to facilitate accurate control of the discharging time and improve the working efficiency.

[0063] In some embodiments, the feeding reaction device 10 further includes a plurality of third control valves 15, each of which is arranged corresponding to each feeding reactor 11. Exemplarily, each third control valve 15 is arranged at the discharge pipe of each feeding reactor 11, and is used to control the opening and closing of the discharge part 13. It can be understood that in some embodiments, the feeding reactor 11 can also be discharged by gravity unloading. In this case, there is no need to set up a water pump to save costs. The third control valve 15 is opened, and the weight of the material itself flows out of the feeding reactor 11.

[0064] In some embodiments, see Figure 1 , Figure 3 , Figure 4The second part 112 is conical, which can facilitate the sedimentation of impurities such as sludge in the material in the second part 112. It can be understood that the present application does not limit the shape of the second part 112, for example, it can also be a cylindrical shape.

[0065] In some embodiments, see Figure 1 , Figure 3 , Figure 4 The feeding reaction equipment 10 includes a plurality of stirring parts 16, each stirring part 16 is arranged corresponding to each feeding reactor 11, each stirring part 16 is arranged inside each feeding reactor 11, the stirring part 16 is used to rotate the material along the second direction Q, and the feeding pipe 121 is used to allow the material to enter the feeding reactor 11 along the third direction E, and the second direction Q is opposite to the third direction E. In this way, when the material enters the inside of the feeding reactor 11 tangentially along the feeding pipe 121, because the stirring part 16 causes the existing material in the feeding reactor 11 to rotate along the second direction Q, the material newly entering the feeding reactor 11 and the existing material in the feeding reactor 11 collide with each other, which can achieve a better mixing effect.

[0066] In some embodiments, the stirring part 16 includes one of a propeller stirrer, a paddle stirrer and a turbine stirrer. The present application does not limit the specific type of the stirrer.

[0067] In some embodiments, see Figure 1 , Figure 3 , Figure 4 , the feed reactor 11 includes a plurality of spoilers 113, and the plurality of spoilers 113 are arranged at intervals on the inner wall 114 of the first part 111, and each spoiler 113 is extended along the first direction X. Exemplarily, the spoiler 113 is convexly arranged on the inner wall 114 of the feed reactor 11, and the width of the spoiler 113 is one tenth of the diameter or side length of the feed reactor 11. Under the action of the stirring part 16, the material inside the feed reactor 11 rotates in a fixed direction (such as the second direction Q). Under the action of the spoiler 113 of the inner wall, the laminar state of the material close to the inner wall is destroyed, thereby forming a turbulent state that is conducive to the mixed reaction, so that the material and the agent can be fully mixed and reacted, and the utilization rate of the agent is further improved. It can be understood that the width of the spoiler 113 is not limited in the present application, for example, it can also be one eleventh, one eighth, one ninth, etc. of the diameter or side length of the feed reactor 11.

[0068] Exemplarily, the feeding reactor 11 includes four spoilers 113, and the four spoilers 113 are spaced apart on the inner wall 114 of the first part 111. It can be understood that the present application does not limit the number of spoilers 113, for example, it can also be 2, 3, 5, 6, 7 or the like.

[0069] In some embodiments, see Figure 5 The present application also provides a feed reaction method, which uses the above-mentioned feed reaction precipitation system, and the steps are as follows:

[0070] S1: When one of the N feeding reactors is switched to the first state, the remaining N-1 unfed feeding reactors are in the second state.

[0071] For example, combined with Figure 1 It can be seen that when the aforementioned N feeding reactors are 3, the 3 feeding reactors 11 are numbered A, B, and C, respectively. When one of the 3 feeding reactors (which can be the A feeding reactor, the B feeding reactor, or the C feeding reactor) is switched to the first state, the remaining 2 unfed feeding reactors are in the second state. For ease of explanation, illustratively, when the A feeding reactor is switched to the first state, the unfed B feeding reactor and the C feeding reactor are both in the second state, and the A feeding reactor can be used for feeding and adding medicine.

[0072] S2: After a set time, one of the remaining N-1 unfed feeding reactors is switched to the first state, and the fed feeding reactor and the remaining N-2 unfed feeding reactors are switched to the second state.

[0073] Exemplarily, after the set time, one of the remaining two unfed feeding reactors is switched to the first state, that is, one of the B feeding reactor and the C feeding reactor is switched to the first state. For ease of explanation, exemplarily, the B feeding reactor is switched to the first state, at which time the A feeding reactor after feeding and the remaining C feeding reactor without feeding are switched to the second state, that is, at this time, the A feeding reactor has completed the feeding, and the material and the reagent have begun to mix and react.

[0074] S3: Execute the above steps in sequence until the last feeding reactor among the unfed feeding reactors is in the first state.

[0075] Exemplarily, the aforementioned steps are performed in sequence until the last feeding reactor among the unfed feeding reactors is in the first state, i.e., the unfed feeding reactor C is switched to the first state, at which time the feeding reactors A and B after feeding have completed feeding and are in the second state.

[0076] S4: After a set time, the last feeding reactor switches to the second state.

[0077] Exemplarily, after a set time, the last feeding reactor (i.e., the C feeding reactor) is switched to the second state. At this point, the three feeding reactors A, B, and C have all completed feeding and are in the second state for fully reacting the material and the reagent.

[0078] By adopting the above technical scheme, the continuous water intake and continuous dosing of reagents can be adjusted to a sequential batch water intake and dosing method. Sequential batch water intake and dosing means that after the feeding and dosing of the feeding reactor are completed, the feeding and dosing are stopped, and a stirring reaction is started for a period of time until the reaction is sufficient before discharging the material. The feeding reaction method provided in the present application can ensure the full reaction of the material and the reagent, thereby greatly improving the utilization rate of the reagent and saving the reagent consumption.

[0079] In some embodiments, see Figure 6 The feeding reaction method further includes a discharging step S5. For convenience of explaining the discharging step S5, the three feeding reactors 11 of A, B and C are still taken as an example. Figure 1 Provide explanation.

[0080] S51: When the last feeding reactor is switched to the second state, the discharge portion 13 of the first feeding reactor is opened, and the remaining N-1 feeding reactors after feeding are in the second state.

[0081] Exemplarily, when the last feeding reactor is switched to the second state, that is, the C feeding reactor is switched to the second state, it means that the feeding and dosing processes of all feeding reactors have been completed. At this time, since the first feeding A feeding reactor enters the mixed reaction state first, it is possible to choose to open the discharge part 13 of the A feeding reactor to allow the material in the A feeding reactor to flow into the coagulation reactor 20, and the remaining two feeding reactors (B feeding reactor and C feeding reactor) after feeding are still in the second state.

[0082] S52: After a set time, the discharge portion 13 of the second feeding reactor is opened, the first feeding reactor is switched to the first state, and the remaining N-2 feeding reactors after feeding are in the second state.

[0083] Exemplarily, after a set time, the discharge portion 13 of the second feeding reactor (i.e., the B feeding reactor) opens. At this time, the first feeding reactor (A feeding reactor) has completed the discharge. Therefore, it is possible to choose to switch the A feeding reactor to the first state for a new round of feeding operation, and the remaining C feeding reactor after feeding is in the second state.

[0084] S53: Execute the above steps in sequence until the discharge portion 13 of the last feeding reactor of the Nth feed is opened, and the feeding reactor of the N-1th feed is switched to the first state.

[0085] Exemplarily, the aforementioned steps are performed in sequence until the discharge portion 13 of the last feeding C feeding reactor is opened, at which time the second feeding feeding reactor (B feeding reactor) has completed the discharge, so the B feeding reactor can be selected to switch to the first state.

[0086] S54: After a set time, the last feeding reactor of the Nth feed is switched to the first state.

[0087] Exemplarily, after a set time, the last feeding reactor (i.e., C feeding reactor) switches to the first state. So far, the three feeding reactors A, B, and C have all completed discharging and can be used for a new round of feeding.

[0088] In some embodiments, each feeding reactor is controlled to switch between the first state and the second state according to the mixing reaction time of the agent and the material and the set time, so that uninterrupted continuous feeding can be achieved, as described in detail as follows:

[0089] When the mixing reaction time of the agent and the material is at least N times the set time, for example, when the N feeding reactors of the feeding reaction equipment 10 are specifically 3 feeding reactors, and the set time is 20 minutes, the mixing reaction time of the agent and the material is 3×20=60 minutes. Then, when the A feeding reactor starts feeding, after 20 minutes, the B feeding reactor starts feeding; after another 20 minutes, the C feeding reactor starts feeding, and the B feeding reactor completes the feeding, at this time, the A feeding reactor has reacted for 40 minutes; after another 20 minutes, the C feeding reactor completes the feeding, at this time, the A feeding reactor has reacted for 60 minutes, and the B feeding reactor has reacted for 40 minutes. It can be understood that the present application does not limit the set time and the mixing reaction time, and can be set according to actual needs. For example, the set time can also be set to 10 minutes, 30 minutes, etc.

[0090] That is to say, at this time, the A feeding reactor is ready to discharge materials. The discharge part 13 of the A feeding reactor can be opened and the discharge time of the A feeding reactor can be controlled to be the set time. In this way, the mixing reaction time of the reagent and material in the A feeding reactor can be further extended.

[0091] When the discharge part 13 of the A feeding reactor is opened, after another 20 minutes, the B feeding reactor has reacted for 60 minutes, the C feeding reactor has reacted for 40 minutes, and the A feeding reactor has completed the discharge, and the A feeding reactor is switched to the first state for a new round of feeding to achieve continuous feeding, which can further improve the work efficiency. At this time, the discharge part 13 of the B feeding reactor is opened, and the discharge time of the B feeding reactor is controlled to be the set time.

[0092] When the discharge part 13 of the B feed reactor is opened, after another 20 minutes, the C feed reactor has reacted for 60 minutes, the B feed reactor has completed the discharge, the B feed reactor is switched to the first state, and the A feed reactor has completed a new round of feeding, and the A feed reactor is switched to the second state. At this time, the discharge part 13 of the C feed reactor is opened, and the discharge time of the C feed reactor is controlled to be the set time. After 20 minutes, the C feed reactor has completed the discharge, the C feed reactor is switched to the first state, and the B feed reactor has completed a new round of feeding, and the B feed reactor is switched to the second state. It can be understood that after the three feed reactors A, B, and C have completed the discharge, steps S1-S4 can be repeated to achieve continuous feeding.

[0093] Through the above technical scheme, steps S1-S5 can be executed in a continuous cycle to achieve uninterrupted continuous feeding, which can not only enable the reagents and materials to fully react in the feeding reactor and improve the utilization rate of the reagents in the reactor, but also ensure that the feeding reaction equipment has a high working efficiency.
