[0026] Reference Figures 1 to 7, the sewage impurity attachment and scale prevention interception treatment equipment according to the preferred embodiment of the utility model will be described in detail below, the sewage impurity attachment and scale prevention interception treatment equipment includes a removing device 10 and a filter component 20, wherein the removing device 10 is used to draw sewage in the sewage pool and remove impurities in the drawn sewage. The filter component 20 is used to filter the sewage removed by the removing device 10.

[0027] Specifically, the removing device 10 includes a liquid drawing unit 11, at least one removing body 12 and the same number of agent passing members 13 as the removing body 12, wherein the liquid drawing unit 11 has a liquid drawing pipe part 111 for drawing sewage, and the liquid drawing unit 11 also has a liquid passing pipe part 112 for connecting the removing body 12. The removing body 12 has an inlet 1201, an outlet 1202 and a removing cavity 1203 arranged between and connected with the inlet 1201 and the outlet 1202, and the inlet 1201 is arranged to be connected with a port of the liquid passing pipe part 112, so that when the liquid drawing unit 11 is placed in the sewage pool and the sewage submerges the port of the liquid drawing pipe part 111, the liquid drawing unit 11 is arranged to be able to guide the sewage to be sucked from the liquid drawing pipe part 111 into the liquid passing pipe part 112 to pass the sewage into the inlet 1201 of the removing body 12.

[0028] The agent passing member 13 is arranged to pass the agent into the removing cavity 1203, so that the sewage passing into the removing cavity 1203 can be removed.

[0029] It can be understood that when the sewage is passed into the removing cavity 1203 of the removing body 12 by the liquid drawing unit 11, the agent passing member 13 simultaneously passes the agent into the removing cavity 1203, so that the agent can timely contact the sewage and react with the nitrogen and phosphorus substances in the sewage, thereby completing the removing operation.

[0030] Preferably, the liquid drawing unit 11 is implemented as a lifting pump.

[0031] In one embodiment, as shown in Figures 1 to 3 The number of the removing body 12 is arranged to be two, and the two removing bodies 12 are arranged in a front-rear arrangement along the sewage passing direction, and the inlet 1201 of the removing body 12 at the rear is arranged to be connected with the outlet 1202 of the removing body 12 at the front. Correspondingly, the number of the agent passing member 13 is arranged to be two, and each agent passing member 13 is arranged to pass the agent into the removing cavity 1203 of one removing body 12.

[0032] It should be noted that when the sewage is introduced into the impurity removal cavities 1203 of the impurity removal bodies 12 from the liquid passage portions 112 of the liquid suction units 11, the sewage can pass through the two impurity removal bodies 12 in sequence to perform two impurity removal operations, so that the impurities in the sewage can fully react with the reagents, thereby enabling the nitrogen and phosphorus in the sewage to be more fully removed.

[0033] In another embodiment, the number of the impurity removal bodies 12 is set to two, and the two impurity removal bodies 12 are arranged side by side, and the inlets 1201 of the two impurity removal bodies 12 are simultaneously communicated with the same port of the liquid passage portion 112. Correspondingly, the number of the reagent passage members 13 is set to two, and each reagent passage member 13 is arranged to introduce the reagent into the impurity removal cavity 1203 of one impurity removal body 12.

[0034] It should be noted that the side-by-side arrangement of the two impurity removal bodies 12 can increase the amount of sewage that can be removed in a single time, thereby improving the overall sewage removal efficiency.

[0035] In order for those skilled in the art to understand the present application, the present application is described below by taking at least one embodiment as an example, in which the number of the impurity removal bodies 12 is set to two, and the two impurity removal bodies 12 are arranged in a front-rear arrangement along the sewage introduction direction, and the inlet 1201 of the rear impurity removal body 12 is arranged to be communicated with the outlet 1202 of the front impurity removal body 12, that is, the sewage flows through the two impurity removal bodies 12 in sequence and is then filtered by the impurity filtering assembly 20.

[0036] Preferably, as shown in Figure 1 and Figure 2 The reagent passage member 13 includes a reagent storage member 131 and a reagent guide member 132, wherein the reagent storage member 131 is arranged to store the reagent. The reagent guide member 132 is communicated with the reagent storage member 131 and the impurity removal body 12, and the reagent guide member 132 is arranged to guide the reagent in the reagent storage member 131 to the impurity removal cavity 1203 of the impurity removal body 12, so that when the sewage is introduced into the impurity removal cavity 1203 of the impurity removal body 12 from the liquid passage portion 112 of the liquid suction unit 11, the reagent stored in the reagent storage member 131 can be introduced into the impurity removal cavity 1203 in time to react with the impurities in the sewage.

[0037] Preferably, the communication position of the reagent guide member 132 and the impurity removal body 12 is arranged close to the position where the inlet 1201 of the impurity removal body 12 is located, so that the sewage can react with the reagent in time as soon as it enters the interior of the impurity removal body 12.

[0038] As preferred, the guide member 132 is implemented as a one-way valve.

[0039] Further, the impurity removing device 10 also comprises the same number of stirring assemblies 14 as the impurity removing body 12, each of which is used to fully mix the medicament and sewage in the impurity removing cavity 1203 to remove the impurities in the sewage.

[0040] Preferably, the stirring assembly 14 comprises a driving unit 141 and a stirring shaft 142, wherein the stirring shaft 142 is rotatably connected to the driving end of the driving unit 141 in one of the impurity removing cavities 1203, and the stirring shaft 142 extends to the bottom wall forming the impurity removing cavity 1203 by a predetermined length, and the circumferential direction of the stirring shaft 142 has a blade portion extending in the axial direction and in a spiral shape, and when the sewage is introduced into the impurity removing cavity 1203, the driving unit 141 is started to drive the stirring shaft 142 to rotate in the impurity removing cavity 1203, at this time, the medicament and sewage are stirred and fully mixed together by the rotating stirring shaft 142.

[0041] It is worth mentioning that the mixed medicament and sewage can also be transported by the stirring shaft 142 to the outlet 1202 of the impurity removing body 12.

[0042] Specifically, the impurity filtering assembly 20 comprises at least one liquid passing container 21, the same number of screening units 22 and rebounding members 23 as the liquid passing container 21, wherein the liquid passing container 21 has a liquid passing cavity 2101 and a liquid outlet pipeline 211 communicating with the liquid passing cavity 2101. The screening unit 22 is arranged in the liquid passing cavity 2101 and spaced apart from the inner wall forming the liquid passing cavity 2101 by a predetermined distance, and the screening unit 22 forms a screening passage 2201 communicating with the outlet 1202 of the impurity removing body 12 along the sewage flow direction, and the screening unit 22 is uniformly provided with a plurality of screen holes of a predetermined size and communicating with the screening passage 2201 and the liquid passing cavity 2101 at the circumferential position along the forming direction of the screening passage 2201. The rebounding member 23 is sleeved on the outer wall of the screening unit 22, and the rebounding member 23 is connected to the end of the liquid passing container 21, so that when the sewage is introduced into the screening passage 2201, the rebounding member 23 is arranged to be able to deform along the radial direction of the screening unit 22 to swing the screening unit 22.

[0043] As can be understood by those skilled in the art, when the sewage flows from the outlet 1202 of the impurity-removing body 12 to the screening channel 2201 of the screening unit 22, the screening unit 22 is driven to swing in the liquid passing cavity 2101 due to the deformation of the rebounding member 23 along the radial direction of the screening unit 22 and the impact force generated by the sewage flowing through the screening channel 2201.

[0044] Thus, after the screening unit 22 filters a predetermined amount of sewage, the impurities such as sludge attached to the surface of the screening unit 22 at the screen hole position are thrown away from the screen hole position by the swinging screening unit 22, so that the screen hole is difficult to be clogged by the impurities such as sludge, thereby enabling the sewage to smoothly pass through the screen hole of the screening unit 22 and flow through the gap between the inner wall of the liquid passing cavity 2101 and the outer wall of the screening unit 22, and then flow out from the liquid outlet pipeline 211 of the liquid passing container 21.

[0045] In this way, the screening unit 22 not only can filter and collect impurities in the sewage through the screening channel 2201, but also can prolong the single use time of the screening unit 22 for filtering sewage, thereby not needing to be frequently replaced.

[0046] Preferably, the liquid passing container 21 is vertically erected to hang the screening unit 22 in the liquid passing cavity 2101. It should be noted that when the sewage inside the impurity-removing body 12 stops flowing to the screening unit 22, the part of the sewage remaining in the screening channel 2201 can still gradually flow to the bottom of the liquid passing container 21 under the action of gravity.

[0047] More preferably, the inlet of the liquid outlet pipeline 211 is arranged at the bottom of the liquid passing container 21, and the outlet of the liquid outlet pipeline 211 extends to the inside of the sewage collecting platform 90, so that at least part of the sewage remaining in the screening channel 2201 can directly flow into the inlet of the liquid outlet pipeline 211 when flowing to the bottom of the liquid passing container 21.

[0048] In one embodiment, as shown in Figure 4 and 5 The number of the liquid passing containers 21 is two, and the two liquid passing containers 21 are arranged side by side. The number of the screening units 22 and the rebounding members 23 is also two, and each of the screening units 22 is arranged in the liquid passing cavity 2101 of one of the liquid passing containers 21, and in addition, the screening channels 2201 of the two screening units 22 are arranged to simultaneously communicate with the outlet 1202 of the same impurity-removing body 12.

[0049] It can be understood that the two liquid passing containers 21 are arranged in parallel, so that the capacity of sewage filtered in a single time is increased, which is beneficial to improve the overall filtration efficiency of the sewage.

[0050] In another embodiment, the number of the liquid passing containers 21 is still two, and the two liquid passing containers 21 are arranged in a front-rear arrangement along the flow direction of the sewage. The screening units 22 and the rebounding members 23 are both two, and each of the screening units 22 is arranged in the liquid passing cavity 2101 of one of the liquid passing containers 21. In addition, the screening channel 2201 of the rear screening unit 22 is arranged in communication with the liquid outlet pipeline 211 of the front liquid passing container 21.

[0051] It can be understood that the sewage is filtered by the front screening unit 22 first, and then filtered by the rear screening unit 22. That is, the sewage is filtered twice in succession, so that the impurity content in the finally flowing sewage is less, and thus it is easy to meet the discharge standard.

[0052] In order for those skilled in the art to understand the present application, the number of the liquid passing containers 21 is two, and the two liquid passing containers 21 are arranged in parallel in the following at least one embodiment of the present application. The screening units 22 and the rebounding members 23 are both two, and each of the screening units 22 is arranged in the liquid passing cavity 2101 of one of the liquid passing containers 21. In addition, the screening channels 2201 of the two screening units 22 are arranged to be simultaneously communicated to the outlet 1202 of the same impurity removing body 12, which is taken as an example to illustrate, that is, to improve the capacity of sewage filtered in a single time.

[0053] Preferably, a plurality of support structures 221 are uniformly arranged at circumferential positions along the forming direction of the screening channel 2201, and each of the support structures 221 forms a ring around the outer wall of the screening unit 22, so that when the screening unit 22 is swung, the support structure 221 is arranged to be able to touch the inner wall forming the liquid passing cavity 2101.

[0054] In this way, the screening channel 2201 can not only be supported by the support structure 221 to maintain the same inner diameter, but also the whole screening unit 22 will vibrate when the support structure 221 touches the inner wall forming the liquid passing cavity 2101, so that the impurities in the sewage are difficult to adhere and scale at the position where the screen holes are formed, thereby making it difficult to bring difficulties to the filtration operation of the screening unit 22.

[0055] Preferably, the screening unit 22 is arranged as a cloth bag with screen holes.

[0056] Preferably, the resilient member 23 is supported by a flexible material, such as a rubber ring.

[0057] Further, the impurity filtering assembly 20 further comprises a positioning member 24, which is used to maintain the placement posture of the liquid passing container 21, and prevent the liquid passing container 21 from being deviated or tilted by external force when the inner wall of the liquid passing cavity 2101 is touched by the swinging screening unit 22.

[0058] In one embodiment, as shown in Figure 4 and 5 the positioning member 24 comprises a fixed body 241 and a same number of limit members 242 as the liquid passing containers 21, wherein the fixed body 241 forms an accommodating cavity 24101 for accommodating the liquid passing containers 21 and a same number of connecting channels 24102 as the limit members 242 and arranged at the bottom wall of the accommodating cavity 24101, and each of the connecting channels 24102 is arranged to simultaneously communicate with the accommodating cavity 24101 and the outside, in addition, the fixed body 241 is uniformly and spacedly provided with a plurality of support legs 2411 of a predetermined length at the bottom to support the sewage collecting table 90.

[0059] It is worth mentioning that one end of the liquid passing container 21 is connected to the top wall forming the accommodating cavity 24101, and the other end of the liquid passing container 21 is spaced a predetermined distance from the bottom wall forming the accommodating cavity 24101.

[0060] The limit member 242 is movably connected to the connecting channel 24102 of the fixed body 241, and the front end of the limit member 242 is at least partially located in the accommodating cavity 24101, and the limit member 242 forms a groove 24201 at the front end position towards one end of the liquid passing container 21, the size of the groove 24201 is adapted to the outer diameter of the liquid passing container 21, so that when the limit member 242 moves towards the liquid passing container 21, the end of the liquid passing container 21 close to the limit member 242 is at least partially accommodated in the groove 24201.

[0061] It can be understood that when the swinging screening unit 22 touches the inner wall of the liquid passing container 21, due to the limiting effect of the groove 24201, the end of the liquid passing container 21 located in the groove 24201 abuts against the inner wall forming the groove 24201 and is difficult to shake, and at the same time, since the other end of the liquid passing container 21 is connected to the top wall of the accommodating cavity 24101, the whole liquid passing container 21 is limited and difficult to be affected by the swinging screening unit 22.

[0062] It can be further supplemented that, as in a variant embodiment, the positioning member 24 comprises a fixed body 241 and the same number of limiters 242 as the liquid passing container 21, wherein the fixed body 241 forms an accommodating cavity 24101 for accommodating the liquid passing container 21 and the same number of connecting channels 24102 as the limiters 242 and arranged at the bottom wall of the accommodating cavity 24101, and each of the connecting channels 24102 is arranged to simultaneously communicate with the accommodating cavity 24101 and the outside, in addition, the fixed body 241 is uniformly and spacedly provided with a plurality of predetermined length supporting legs 2411 at the bottom to support on the sewage collecting platform 90.

[0063] One end of the liquid passing container 21 is connected to the top wall forming the accommodating cavity 24101, and the other end of the liquid passing container 21 is spaced a predetermined distance from the bottom wall forming the accommodating cavity 24101, and the end of the liquid passing container 21 close to the bottom wall of the accommodating cavity 24101 forms a limiting channel communicating with the accommodating cavity 24101 and having a notch facing one of the connecting channels 24102.

[0064] The limiter 242 is movably connected to the connecting channel 24102 of the fixed body 241, and the front end of the limiter 242 is at least partially located in the accommodating cavity 24101, and the outer diameter of the front end of the limiter 242 is adapted to the size of the limiting channel, so that when the limiter 242 moves towards the liquid passing container 21, the front end of the limiter 242 is at least partially accommodated in the limiting channel. In this way, the inner wall of the limiting channel is abutted by the front end of the limiter 242, so that the end of the liquid passing container 21 forming the limiting channel is limited, and in addition, the other end of the liquid passing container 21 is connected to the top wall of the accommodating cavity 24101, so that the whole liquid passing container 21 is limited in the accommodating cavity 24101.

[0065] Preferably, the connecting channel 24102 is provided as a threaded hole, and the limiter 242 is connected to the fixed body 241 in a threaded connection manner.

[0066] Preferably, the limiter 242 further comprises a guide portion 2421 in the form of a ring at the notch of the groove 24201, and the guide portion 2421 has an arc-shaped guide surface convexly facing the groove bottom of the groove 24201, so that when the limiter 242 moves towards the liquid passing container 21, the end of the liquid passing container 21 close to the bottom wall of the accommodating cavity 24101 can be gradually accommodated in the groove 24201 along the arc-shaped guide surface of the guide portion 2421.

[0067] Further preferably, the limiting member 242 forms a driving portion 2422 of a predetermined length at an end portion outside the fixing body 241, the driving portion 2422 being used for manual force application to drive the limiting member 242 to move, or being used for jointing with other driving devices to drive the limiting member 242 to move, so that the liquid container 21 can be limited.

[0068] In addition, the sewage impurity attachment and fouling prevention interception treatment device further comprises a flow control unit 30, as shown in Figure 1 、 Figure 2 and Figure 4 The flow control unit 30 comprises a first flow control member 31 and a second flow control member 32.
