DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0034] Referring to Figures 1 to 11 : The combined wastewater treatment mechanism comprises a filter and sedimentation structure 1, a water inlet pipe 2, a water outlet pipe 3 and a pushing mechanism 4; the filter and sedimentation structure 1 comprises a sedimentation tank 11, two partition plates 12 for separating the inside of the sedimentation tank 11 into three cavities and a switching plate 13 for separating one side cavity from the other two cavities, the upper end of the sedimentation tank 11 is further provided with a filter structure 14, and the bottom of the sedimentation tank 11 is provided with two first cleaning ports 111; the water inlet pipe 2 is arranged inside the water outlet pipe 3, the channel between the water inlet pipe 2 and the water outlet pipe 3 is a water outlet channel, a water outlet 31 is formed on the water outlet pipe 3, and the water outlet 31 is higher than the filter structure 14; the pushing mechanism 4 is arranged inside the sedimentation tank 11, and the pushing mechanism 4 comprises two guide structures 41 and a pushing driving structure 42, the two guide structures 41 are respectively arranged obliquely on the two sides of the switching plate 13, and the pushing driving structure 42 is arranged between the two guide structures 41, and the pushing driving structure 42 is used for adjusting the inclination angle of the guide structure 41.

[0035] Before the combined wastewater treatment mechanism is put into operation, the switching plate 13 is first moved to abut against one of the two partition plates 12, at this time, a large cavity in communication with the water inlet pipe 2 is formed in the sedimentation tank 11, and the first cleaning port 111 in the large cavity is in a closed state to prevent wastewater leakage, thus preparing for wastewater treatment, when the equipment is started to introduce wastewater, the wastewater flows into the sedimentation tank 11 through the water inlet pipe 2, as the wastewater continuously flows in, the water level in the sedimentation tank 11 gradually rises, and the wastewater first passes through the filter structure 14 arranged at the upper end of the sedimentation tank 11, and the filter structure 14 intercepts the larger impurities in the wastewater, thus preliminarily purifying the wastewater.

[0036] The filtered wastewater continues to flow into the water outlet channel between the water inlet pipe 2 and the water outlet pipe 3, and since the water outlet 31 on the water outlet pipe 3 is higher than the filter structure 14, the wastewater is finally discharged from the water outlet 31 of the water outlet pipe 3 out of the combined wastewater treatment mechanism, thus completing a wastewater treatment process, and in the wastewater treatment process, the solid impurities in the wastewater gradually precipitate in the sedimentation tank 11, at this time, the pushing mechanism 4 arranged inside the sedimentation tank 11 works, the two guide structures 41 in the pushing mechanism 4 are respectively arranged obliquely on the two sides of the switching plate 13, the guide structures 41 guide the solid impurities in the sedimentation process to move in the direction of the first cleaning port 111, thus facilitating the subsequent concentrated discharge of the solid impurities.

[0037] The pushing driving structure 42 is started in time to push the guide structure 41 to move, so that the inclination angle of the guide structure 41 is reduced, in the process, the end of the guide structure 41 away from the switching plate 13 is further away from the switching plate 13, and the solid waste in front of the guide structure 41 is pushed to move to the first cleaning port 111, when the guide structure 41 is reset, the solid waste near the upper end of the guide structure 41 falls down due to the loss of support of the solid waste below, effectively avoiding the accumulation of solid waste between the switching plate 13 and the non-adjacent partition plate 12, when a large amount of solid waste is stored in the large cavity, and the cleaning is needed, the switching plate 13 is moved to abut against another partition plate 12.

[0038] The precipitation tank 11 is further divided into a new large cavity in communication with the water inlet pipe 2, and the subsequent wastewater flowing through the precipitation tank 11 is continuously filtered and precipitated, and the cavity for storing the solid waste is emptied by opening the corresponding first cleaning port 111, so that the solid waste is smoothly discharged from the first cleaning port 111, so that the cavity is emptied and the space for storing the solid waste is re-gained, and the wastewater treatment and solid waste cleaning are alternately performed, the guide structure 41 is driven by the pushing driving structure 42 to move the solid waste in time, so that the switching plate 13 can completely abut against the partition plate 12 after switching, and the wastewater is prevented from flowing into the cavity for desilting.

[0039] Referring to Figure 3 , Figure 4 and Figure 5 , the guide structure 41 comprises a guide plate 411, a movable plate 412 and a cover plate 413; one side of the guide plate 411 is rotatably connected with the switching plate 13, and the guide plate 411 is connected with the pushing driving structure 42; the movable plate 412 is arranged on the other side of the guide plate 411, and the movable plate 412 is movably connected with the guide plate 411; and the cover plate 413 is used for covering the movement range between the guide plate 411 and the movable plate 412.

[0040] When the pushing driving structure 42 is started to push the guide structure 41 to move, the guide plate 411 starts to rotate, and the included angle between the guide plate 411 and the switching plate 13 gradually increases, in the process, to ensure that the end of the guide structure 41 away from the switching plate 13 always abuts against the bottom of the precipitation tank 11, the movable plate 412 will rotate synchronously with the guide plate 411, and as the rotation amplitude of the guide plate 411 increases, the movable plate 412 gradually moves away from the guide plate 411, at the same time, the cover plate 413 moves with the movable plate 412, and always covers the space region newly formed between the movable plate 412 and the guide plate 411, effectively preventing the solid waste from moving to the other side of the guide plate 411, avoiding the accumulation of the solid waste at the unintended position, and ensuring that the solid waste can move to the direction of the first cleaning port 111 under the action of the guide plate 411.

[0041] When the pushing material driving structure 42 pushes the guide plate 411 to a predetermined angle, it starts to reverse to reset the guide plate 411, and the included angle between the guide plate 411 and the switching plate 13 decreases. At this time, the movable plate 412 will also move close to the guide plate 411 with the rotation of the guide plate 411. In the whole process of reciprocating movement of the guide plate 411, the movable plate 412 can always be in abutting state with the bottom of the sediment tank 11 through the movable connection relationship with the guide plate 411, so that the solid impurities cannot move from the lower end of the guide structure 41 to the space between the guide structure 41 and the switching plate 13, thereby ensuring the accuracy and stability of the guide direction of the guide structure 41 to the solid impurities, and continuously assisting the solid impurities to smoothly concentrate to the first cleaning port 111.

[0042] Referring to Figure 3 , Figure 4 and Figure 6 , the pushing mechanism 4 further comprises a pushing structure 43, the pushing structure 43 comprises a guide rod 431 and two pushing plates 432; the guide rod 431 is perpendicular to the switching plate 13, and the middle part of the guide rod 431 is fixedly connected with the switching plate 13; the two pushing plates 432 are respectively slidably connected with the two ends of the guide rod 431, and the two pushing plates 432 are respectively rotatably connected with the two movable plates 412.

[0043] When the pushing material driving structure 42 starts to drive the guide plate 411 to rotate, the pushing effect of the guide plate 411 on the solid impurities will gradually decrease as the included angle between the guide plate 411 and the switching plate 13 gradually increases. Therefore, the pushing structure 43 is arranged to play a role in the movement process of the guide plate 411. When the guide plate 411 rotates around the rotating connection part thereof and the switching plate 13, an action force away from the switching plate 13 is applied to the pushing plate 432 through the movable plate 412. Under the action of the action force, the pushing plate 432 starts to move along the guide rod 431. Since the guide rod 431 is vertically fixed on the switching plate 13, the guide rod 431 provides a clear path limitation for the movement of the pushing plate 432, so as to ensure that the pushing plate 432 can only move in the direction of the guide rod 431, and the lower part of the pushing plate 432 abuts against the inner bottom surface of the sediment tank 11 during the movement. Therefore, the effect of the pushing plate 432 on the solid impurities in front of the pushing plate 432 remains unchanged during the movement of the pushing plate 432. Regardless of the change of the angle of the guide plate 411, the pushing plate 432 can stably apply a pushing force to the solid impurities to push the solid impurities toward the first cleaning port 111, thereby effectively making up for the problem of weakening of the pushing effect of the guide plate 411, realizing efficient pushing of the solid impurities to move in the sediment tank 11, and guaranteeing that the solid impurities can be smoothly discharged.

[0044] Referring to Figure 6 , a strip-shaped groove 4321 is formed in the pushing plate 432, and the strip-shaped groove 4321 is located above the rotating connection part of the pushing plate 432 and the movable plate 412.

[0045] When the pushing driving structure 42 drives the guide plate 411 to rotate, the included angle between the guide plate 411 and the partition plate 12 increases, and the included angle between the movable plate 412 and the pushing plate 432 also increases, and the space between them becomes larger. In this process, the solid impurities attached to the movable plate 412 will slide into the space between the movable plate 412 and the pushing plate 432. When the guide plate 411 reversely rotates and the included angle between the guide plate 411 and the partition plate 12 decreases, the included angle between the movable plate 412 and the pushing plate 432 will also decrease accordingly. However, at this time, the solid impurities in the included angle between the movable plate 412 and the pushing plate 432 will hinder the decrease of the included angle between the movable plate 412 and the pushing plate 432, affecting the normal reset. Therefore, a strip-shaped slot 4321 is formed on the pushing plate 432. During the process that the pushing plate 432 pushes the solid impurities to move towards the first cleaning port 111, part of the solid impurities will pass through the strip-shaped slot 4321 and move to the rear of the moving direction of the pushing plate 432. This process will not affect the pushing effect of the pushing plate 432 on most of the solid impurities, and the solid impurities can still be effectively pushed.

[0046] When the pushing plate 432 moves towards the switching plate 13 during the reset process, the rear of the moving direction of the pushing plate 432 will be in a state of no solid impurities for a short time. At this time, the solid impurities accumulated between the pushing plate 432 and the movable plate 412 will fall along the strip-shaped slot 4321 to the rear of the moving direction of the pushing plate 432, thereby reducing the accumulation of solid impurities between the pushing plate 432 and the movable plate 412, and enabling the included angle between the pushing plate 432 and the movable plate 412 to change more flexibly, thereby ensuring the smooth operation of the pushing mechanism 4.

[0047] Referring to Figure 7 As shown, a water permeable hole 4111 is formed on the guide plate 411. When the movable plate 412 is in a state close to the guide plate 411, the water permeable hole 4111 is in a closed state. When the movable plate 412 is in a state away from the guide plate 411, the water permeable hole 4111 is in an open state.

[0048] When the wastewater just enters the sediment tank 11, the pushing driving structure 42 has not been started, the guide plate 411 is in the initial position, and the movable plate 412 is close to the guide plate 411. At this time, the water permeable hole 4111 on the guide plate 411 is in a closed state to prevent too much wastewater from flowing into the space between the two guide plates 411, and to ensure that the wastewater is mainly subjected to preliminary purification treatment by the filtering structure 14, thereby preparing for subsequent solid impurity sedimentation and treatment. When the pushing driving structure 42 is started and drives the guide plate 411 to rotate, the angle between the guide plate 411 and the movable plate 412 gradually increases, and the movable plate 412 moves away from the guide plate 411. With the movement of the movable plate 412, the water permeable hole 4111 on the guide plate 411 gradually opens. At this time, part of the wastewater in the sediment tank 11 will pass through the opened water permeable hole 4111 and enter the space between the two guide plates 411, so that this part of the wastewater is temporarily stored in the space.

[0049] When the pushing driving structure 42 drives the guide plates 411 to reset, the space between the two guide plates 411 gradually becomes smaller, and the wastewater stored therein is squeezed, and the squeezed wastewater is sprayed from the water-permeable holes 4111 to form a water flow impacting the solid impurities covering the guide plates 411. The water flow impact force can loosen the solid impurities, separate the solid impurities from the surface of the guide plates 411, and drive the solid impurities to slide downward along the inclined guide plates 411 and move toward the first cleaning port 111, effectively promoting the discharge of the solid impurities, thereby ensuring that the solid impurities cannot accumulate on the guide plates 411, maintaining the cleanliness and good guiding performance of the guide plates 411.

[0050] Referring to Figure 5 and Figure 8 , the pushing driving structure 42 includes a crankshaft 421, a plurality of connecting rods 422, and a rotary driving assembly 423. The crankshaft 421 is arranged in the middle of the two guide plates 411. The plurality of connecting rods 422 are divided into two groups, and the two groups of connecting rods 422 are respectively connected to the crankshaft 421 and the two guide plates 411. The rotary driving assembly 423 is arranged on one side of the crankshaft 421, and the rotary driving assembly 423 is used to drive the crankshaft 421 to rotate.

[0051] When the solid impurities in the sediment tank 11 accumulate to the extent that pushing treatment is required, the rotary driving assembly 423 in the pushing driving structure 42 is started, the rotary driving assembly 423 drives the crankshaft 421 to start rotating, and with the rotation of the crankshaft 421, the two groups of connecting rods 422 connected thereto are driven to move. Since the two ends of the connecting rod 422 are respectively hinged to the crankshaft 421 and the guide plate 411, during the rotation of the crankshaft 421, the connecting rod 422 will convert the circular motion of the crankshaft 421 into the rotation of the guide plate 411, and the two groups of connecting rods 422 will drive the guide plates 411 in the two guide structures 41 to rotate synchronously, so that the two guide plates 411 change the inclination angles at the same time. In the sediment tank 11 that is being desilted, the guide plates 411 after rotation generate a pushing force on the solid impurities, pushing the solid impurities to move toward the first cleaning port 111. The crankshaft 421 continuously rotates, driving the connecting rod 422 to continuously move, and the guide plate 411 also continuously rotates under the driving of the connecting rod 422, continuously applying a pushing force to the solid impurities, efficiently pushing the solid impurities to the first cleaning port 111 for discharge, completing the solid impurities cleaning work, thereby avoiding the problem of solid impurities accumulation and unable to discharge.

[0052] Referring to Figure 3 , Figure 9 and Figure 10The lower end of the sedimentation tank 11 is provided with a dredging mechanism 5, which includes a bottom plate 51 and two screw conveying structures 52. The bottom plate 51 is arranged at the inner bottom of the sedimentation tank 11, and two second cleaning openings 511 are formed in the bottom plate 51. The bottom plate 51 is connected with the switching plate 13. The two screw conveying structures 52 are respectively arranged at the lower ends of the two first cleaning openings 111. The screw conveying structure 52 includes a conveying channel 521 and a screw blade 522. The conveying channel 521 is in communication with the first cleaning opening 111, and the screw blade 522 is arranged in the conveying channel 521.

[0053] When the switching plate 13 moves to abut against one of the partitions 12, a large cavity in the sedimentation tank 11 is formed in communication with the water inlet pipe 2 to carry out wastewater sedimentation. The switching plate 13 drives the bottom plate 51 to move synchronously. On the side where the wastewater is being sedimented, the second cleaning openings 511 on the bottom plate 51 are distributed in a staggered manner with the first cleaning openings 111, so that the first cleaning openings 111 are shielded by the bottom plate 51 and are in a closed state. This effectively prevents the wastewater being treated from flowing into the screw conveying structure 52 from the first cleaning openings 111, and ensures that the wastewater treatment process proceeds normally.

[0054] When the solid impurities in one side of the sedimentation tank 11 accumulate to a certain extent and need to be discharged, the switching plate 13 moves to abut against the other partition 12 and drives the bottom plate 51 to move again. At this time, on the side where the solid impurities are about to be discharged, the second cleaning openings 511 on the bottom plate 51 are completely coincided with the first cleaning openings 111, forming a smooth solid impurity discharge channel. After the solid impurities are pushed by the pushing mechanism 4 towards the first cleaning openings 111, the solid impurities can smoothly pass through the second cleaning openings 511 and the first cleaning openings 111 into the conveying channel 521 of the screw conveying structure 52. The screw blade 522 in the screw conveying structure 52 starts to rotate, and the conveying force generated by the rotation continuously conveys the solid impurities entering the conveying channel 521 to a designated position, completes the cleaning work of the solid impurities, and makes the cavity of the sedimentation tank 11 available for wastewater sedimentation again. Through the switching of the staggered state and the coincided state of the second cleaning openings 511 and the first cleaning openings 111, the automatic switching of the wastewater sedimentation work and the solid impurity discharge work is realized.

[0055] Referring to Figure 9 and Figure 10As shown: the dredging mechanism 5 also includes two auxiliary dredging structures 53, which are arranged between the first cleaning port 111 and the spiral conveying structure 52. The auxiliary dredging structure 53 is used to assist the settled solid debris to enter the spiral conveying structure 52. The auxiliary dredging structure 53 includes a right-angle elbow 531, a dredging rod 532 and a dredging claw 533. The vertical section of the right-angle elbow 531 is connected to the first cleaning port 111, and the horizontal section of the right-angle elbow 531 is connected to the conveying channel 521. One end of the dredging rod 532 extends into the vertical section of the right-angle elbow 531, and the dredging rod 532 is movably connected to the right-angle elbow 531. The dredging claw 533 is installed on one end of the dredging rod 532 extending into the right-angle elbow 531.

[0056] When the solid debris in the sedimentation box 11 accumulates and needs to be discharged, the switching plate 13 moves to make the first cleaning port 111 and the second cleaning port 511 completely overlap, and the solid debris begins to fall under the action of gravity. However, since the solid debris has a certain viscosity, it may stick to each other during the falling process, blocking the falling channel formed by the first cleaning port 111 and the right-angle bend 531, making it difficult for the solid debris to smoothly enter the spiral conveying structure 52. At this time, the auxiliary silt removal structure 53 plays a role, and the silt removal rod 532 is forced toward the inside of the sedimentation box 11 through the automatic control system. The silt removal rod 532 drives the silt removal claw 533 along the vertical section of the right-angle bend 531 to The silt cleaning claw 533 moves in the sedimentation box 11, and can penetrate into the solid debris clumps that stick to each other, push and disperse the solid debris, break the adhesion of the solid debris, and clear the falling channel. Subsequently, a force is applied to the silt cleaning rod 532 away from the sedimentation box 11, and the silt cleaning rod 532 drives the silt cleaning claw 533 to move in the opposite direction and retreat into the right-angle bend pipe 531. During the retreat process, the silt cleaning claw 533 brings the solid debris into the right-angle bend pipe 531. After the solid debris enters the right-angle bend pipe 531, the solid debris is pushed into the conveying channel 521 by subsequent solid debris, thereby avoiding the silt cleaning interruption caused by the blockage of solid debris and significantly improving the silt cleaning efficiency.

[0057] Reference Figure 9 、 Figure 10 and Figure 11 As shown: the dredging mechanism 5 also includes a dredging drive structure 54, which includes a synchronization plate 541 and two elastic connection components 542; the two ends of the synchronization plate 541 are respectively connected to the two auxiliary dredging structures 53; the two elastic connection components 542 are respectively arranged at the two ends of the synchronization plate 541, and the elastic connection component 542 is used to absorb the force of the synchronization plate 541 on the auxiliary dredging structure 53, and the elastic connection component 542 includes a fixed limiting ring 5421 and a spring 5422, the fixed limiting ring 5421 is fixedly installed on the dredging rod 532, the spring 5422 is sleeved on the dredging rod 532, and the two ends of the spring 5422 are respectively in contact with the fixed limiting ring 5421 and the synchronization plate 541.

[0058] When the solid impurities accumulate in the sedimentation tank 11, the synchronization plate 541 starts to move along the axis direction of the dredging rod 532, when the synchronization plate 541 moves towards the sedimentation tank 11, the spring 5422 connected with the synchronization plate 541 transmits the pushing force to the dredging rod 532 through the fixed limiting ring 5421, and drives the dredging claw 533 into the sedimentation tank 11, so as to realize the synchronous driving of the two auxiliary dredging structures 53, since the positions and working states of the two auxiliary dredging structures 53 are different, when the synchronization plate 541 drives one of the auxiliary dredging structures 53 to work, the dredging rod 532 in the other auxiliary dredging structure 53 may be hindered by the bottom plate 51 and cannot be immersed into the sedimentation tank 11, at this time, the dredging rod 532 and the synchronization plate 541 slide relatively, and the spring 5422 in the elastic connecting assembly 542 can absorb the excess pushing force caused by the difference in the working state of the auxiliary dredging structure 53, so as to avoid the deformation of the dredging rod 532 which cannot move under the action of the pushing force of the synchronization plate 541.
