Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an environmentally friendly sewage circulation treatment system. Background Art

[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse. Sewage is mixed with impurities such as sludge and gravel. After processing, the sludge can be used as fertilizer in agricultural production. After the sludge is separated from the sewage, the residual sewage contained in it will be squeezed out first.

[0003] For example, in the prior art, there is an environmentally friendly municipal sewage treatment equipment with a publication number of CN113548782A. The treatment equipment uses a centrifugal method to achieve sludge dehydration treatment. However, since the sludge is often mixed with solid debris such as stones, in order to ensure the quality of the finished fertilizer, additional screening treatment is required before and after dehydration, which increases the treatment steps and reduces the treatment efficiency of the sludge in the sewage.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an environmentally friendly sewage circulation treatment system, which drives multiple metal cages to revolve and rotate through a rotating plate, which not only automatically completes the separation and discharge of stones in the sludge, but also drives the water squeezing component to rotate circumferentially and combines with the mud blocking plate to simultaneously dewater the sludge, thereby accelerating the treatment effect of the sludge in the sewage, and at the same time knocking and vibrating the arc-shaped water filter plate to further accelerate the separation of sewage in the sludge and the cleaning of the sludge on the metal cage; and through the reversal of the rotating plate combined with the water squeezing component, efficient and convenient mud removal operation is achieved, and the mud blocking plate is driven to move with the help of a guide wheel, so that the mud blocking plate automatically makes way before contacting the squeezing plate to prevent motion interference, while ensuring the complete removal of the sludge, to solve the above-mentioned technical defects.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) During the use of the present invention, the sludge in the sewage is trapped in the water filter cylinder, and the rotating plate drives a plurality of metal cages to revolve in the water filter cylinder. When a plurality of U-shaped rods on the metal cages come into contact with the stones in the sludge, the U-shaped rods on both sides of the stones are squeezed and deformed, so that a large gap appears between the U-shaped rods on both sides, forcing the stones to squeeze into the metal cages, and automatically completing the separation of the stones from the sludge as the metal cages revolve. In addition, the metal cage drives the extrusion plate in contact with the arc-shaped water filter plate to rotate circumferentially, separating the stones while simultaneously dehydrating the sludge. Treatment is carried out to improve the treatment efficiency of sludge in sewage; and the sludge blocking plate can effectively prevent the sludge from being pushed to move in the water filter cylinder during the squeezing of the sludge by the squeezing plate, thereby reducing the dehydration efficiency and quality; and in the process of the squeezing plate rotating from the arc cover plate to the arc filter plate, the squeezing plate collides with the mud guide plate with the cooperation of spring 1, forming a knocking vibration on the arc filter plate, thereby further accelerating the separation of sewage in the sludge, thereby achieving an efficient sewage treatment effect, and at the same time, the sludge on the U-shaped rod is vibrated and removed;

[0019] (2) The present invention also utilizes the process of the metal cage revolution to complete the stone separation, combined with the meshing of the rotating gear and the inner gear ring to synchronously rotate, and with the help of multiple internal stone-moving plates, the stones collected in the metal cage are lifted and guided into the stone-discharging cone bucket, and the stones are transferred to the hollow tube for temporary storage through the inclined stone-discharging cone bucket. The hollow tube is connected to the stone-discharging pipe, and the stones are automatically discharged from the water filter cylinder, thereby improving the convenience of stone removal and avoiding the problem that the U-shaped rod and the mud-blocking plate are accidentally deformed and cause the stones in the metal cage to fall into the sludge;

[0020] (3) After the sludge is dehydrated, the rotating plate of the present invention rotates in the opposite direction, and the free side of the extrusion plate fits the inner wall of the arc-shaped water filter plate to shovel the sludge after extrusion and dehydration. After the extrusion plate pushes the sludge to move above the mud guide plate, the mud pushing plate moves synchronously on the extrusion plate under the action of a spring, and scrapes the sludge on the extrusion plate so that it falls onto the mud guide plate and is automatically discharged through the mud outlet, thereby achieving an efficient and convenient mud removal effect; before the extrusion plate reverses and contacts the mud blocking plate, the guide protrusion on the guide wheel contacts the linkage rods on both sides of the mud blocking plate, forcing one end of the mud blocking plate to move completely to the inside of the side wall of the arc-shaped water filter plate, so that the extrusion plate can smoothly fit the arc-shaped water filter plate to complete the mud removal process.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1-Figure 9 As shown, in this embodiment, an environmentally friendly sewage circulation treatment system includes a water filter cylinder 1, and the water filter cylinder 1 includes two groups of symmetrically arranged end panels 11. An arc-shaped water filter plate 12 is fixedly connected between the bottoms of the two groups of end panels 11. The cross section of the arc-shaped water filter plate 12 is a semicircular structure, and a plurality of water filter holes 13 are densely arranged on the arc-shaped water filter plate 12. The sludge in the sewage entering the water filter cylinder 1 is filtered through the water filter holes 13 on the arc-shaped water filter plate 12. The two sides of the water filter cylinder 1 are symmetrically fixedly connected with an annular fixing seat 14 for mounting the rotating component 2;

[0042] A rotating assembly 2 is arranged between the annular fixing seats 14, and the rotating assembly 2 includes a rotating plate 21 rotatably connected to the annular fixing seat 14, and the rotating plate 21 is sealed and rotatably connected to the annular fixing seat 14, and a plurality of connecting rods 22 are fixedly connected between the rotating plates 21, which are used for fixed connection between two groups of rotating plates 21 on the one hand, and cooperate with the metal cage 3 to complete the installation of the water squeezing assembly 4 on the other hand, and a rotating shaft 23 rotatably connected to the corresponding end panel 11 is fixedly connected to the rotating plate 21, and a motor 24 for driving the corresponding rotating shaft 23 to rotate is bolted to the end panel 11;

[0043] A plurality of metal cages 3 are arranged between the rotating plates 21. The metal cages 3 include a rotating disk 31. The rotating disk 31 is installed on the opposite side of the rotating plate 21. A plurality of U-shaped rods 32 are welded equidistantly between the annular outer walls of the rotating disk 31. The motor 24 cooperates with the rotating shaft 23 to drive the two groups of rotating plates 21 to rotate. The rotating plates 21 drive the plurality of metal cages 3 to rotate circumferentially in the water filter cylinder 1, and the U-shaped rods 32 contact the inner concave side of the arc-shaped water filter plate 12. When the plurality of U-shaped rods 32 on the annular outer wall of the rotating disk 31 contact the stones in the sludge, the U-shaped rods 32 in the area are squeezed and deformed, so that a large gap appears between the U-shaped rods 32 on both sides of the stones, thereby forcing the stones to squeeze into the metal cage 3. As the metal cage 3 rotates circumferentially, the separation of the stones in the sludge is automatically completed.

[0044] A water squeezing assembly 4 is provided on the connecting rod 22, and the water squeezing assembly 4 includes a rotating ring 41 rotatably connected to the turntable 31. The rotating ring 41 is rotatably connected to the turntable 31 to prevent the self-rotation of the metal cage 3 from interfering with the fit of the extrusion plate 42 and the arc-shaped water filter plate 12. The extrusion plates 42 are fixedly connected between the rotating rings 41. When the metal cage 3 rotates circumferentially, the corresponding extrusion plates 42 are driven to rotate. The free side of the extrusion plate 42 contacts with the arc-shaped water filter plate 12, and while separating the gravel, the sludge is synchronously squeezed and dehydrated with the arc-shaped water filter plate 12, thereby improving the treatment efficiency of the sludge in the sewage. A plurality of mud blocking plates 5 cooperating with the water squeezing assembly 4 are equidistantly installed on the annular inner wall of the arc-shaped water filter plate 12.

[0045] An arc-shaped cover plate 15 is fixedly connected between the tops of the two groups of end panels 11. The cross section of the arc-shaped cover plate 15 is a semicircular structure, and the diameter of the arc-shaped cover plate 15 is larger than the diameter of the arc-shaped water filter plate 12, so that when the extrusion plate 42 enters the arc-shaped water filter plate 12 from the arc-shaped water filter plate 12, under the action of the spring 1 46, the free side of the extrusion plate 42 is pushed to move to the area between the arc-shaped cover plate 15 and the arc-shaped water filter plate 12, and the rotating plate 21 continues to rotate, and the extrusion plate 42 collides with the mud guide plate 17. In this process, the arc-shaped water filter plate 12 is subjected to knocking vibration, which further accelerates the separation of sewage in the sludge, thereby achieving an efficient sewage treatment effect, and at the same time, the sludge on the metal cage 3 is vibrated and removed;

[0046] A transition plate 16 is fixedly connected between the arc-shaped cover plate 15 and one side of the arc-shaped water filter plate 12, so that the extrusion plate 42 enters the arc-shaped water filter plate 12 from the arc-shaped cover plate 15, and the free side of the extrusion plate 42 can be smoothly guided into the arc-shaped water filter plate 12, thereby completing the circumferential rotation of the water squeezing component 4 in the water filter cylinder 1, and a mud guide plate 17 is fixedly connected between the arc-shaped cover plate 15 and the other side of the arc-shaped water filter plate 12, and a mud outlet is provided on the arc-shaped cover plate 15 and above the mud guide plate 17 The mud guide plate 17 is used for connecting the arc cover plate 15 with the other side of the arc filter plate 12, and the mud guide plate 17 is tilted to facilitate the discharge of sludge. The top of the arc cover plate 15 is fixedly connected with a liquid inlet 19. The sewage is injected into the water filter cylinder 1 through the liquid inlet 19, and the sewage is filtered through the water filter holes 13 on the arc filter plate 12. The sludge and gravel in the sewage are retained in the water filter cylinder 1, so that the sludge is screened and dehydrated. A support plate 110 is welded on the end panel 11.

[0047] A hollow tube 33 rotatably connected to the corresponding turntable 31 is rotatably connected on the rotating plate 21 on the side close to the motor 24, and a hollow shaft 34 fixedly connected to the corresponding turntable 31 is rotatably connected on the rotating plate 21 on the side away from the motor 24. The hollow tube 33 and the hollow shaft 34 are used for installing the two sides of the metal cage 3 and the corresponding rotating plate 21, and a rotating gear 35 is fixedly connected to the hollow shaft 34. An internal gear ring 111 meshing with multiple rotating gears 35 is fixedly connected to the annular fixed seat 14. During the circumferential rotation of multiple metal cages 3 in the water filter cylinder 1, the meshing of the rotating gear 35 and the internal gear ring 111 allows the metal cages 3 to rotate synchronously, thereby avoiding the problem of reducing the service life of the metal cage 3 by separating stones only through deformation of the local U-shaped rod 32.

[0048] A mud pushing plate 43 cooperating with the corresponding connecting rod 22 is provided on one side of the extrusion plate 42. A plurality of guide slide bars 44 slidably connected to the mud pushing plate 43 are fixedly connected to the extrusion plate 42 at equal intervals along its length direction. The guide slide bars 44 are used to increase the sliding stability of the mud pushing plate 43 on the extrusion plate 42. After the sludge dehydration is completed, the motor 24 drives the rotating plate 21 to rotate in the opposite direction. Through the fit between the free side of the extrusion plate 42 and the inner wall of the arc-shaped water filter plate 12, the mud after extrusion and dehydration is shoveled. After the extrusion plate 42 pushes the sludge to move above the mud guide plate 17, the mud pushing plate 43 moves synchronously on the extrusion plate 42 to scrape off the sludge on the extrusion plate 42, so that the sludge falls onto the mud guide plate 17 and is discharged through the mud outlet 18, thereby achieving an efficient and convenient mud collection effect.

[0049] A movable rod 45 is hinged on one side of the mud pushing plate 43, and the end of the movable rod 45 is fixedly connected to a movable sleeve 47 slidably connected thereto by a spring 46, and the movable sleeve 47 is rotatably connected to the corresponding connecting rod 22. Under the compression elastic force of the spring 46 between the movable rod 45 and the movable sleeve 47, the extrusion plate 42 is tightly fitted with the recessed side of the arc-shaped water filter plate 12 through the cooperation of the mud pushing plate 43, and in the process of the extrusion plate 42 entering the arc-shaped water filter plate 12 from the arc-shaped water filter plate 12 into the arc-shaped cover plate 15, it not only pushes the free side of the extrusion plate 42 to be located in the area between the arc-shaped water filter plate 12 and the arc-shaped cover plate 15, but also simultaneously pushes the mud pushing plate 43 to slide on the extrusion plate 42 to achieve the mud scraping effect. A plurality of movable rods 45 and movable sleeves 47 are equidistantly arranged along the length direction of the mud pushing plate 43 to increase the contact force between the extrusion plate 42 and the arc-shaped water filter plate 12, thereby improving the extrusion effect of the residual sewage inside the sludge.

[0050] Example 2: Please refer to Figure 2 , Figure 4 and Figure 9-11 As shown, in this embodiment, a hollow tube 33 rotatably connected to a corresponding turntable 31 is rotatably connected to the rotating plate 21 on the side close to the motor 24, and is used for discharging stones. A hollow shaft 34 fixedly connected to the corresponding turntable 31 is rotatably connected to the rotating plate 21 on the side away from the motor 24, and is used for installing a rotating rod 36. A rotating gear 35 is fixedly connected to the hollow shaft 34, and an internal gear ring 111 meshing with a plurality of rotating gears 35 is fixedly connected to the annular fixed seat 14.

[0051] The hollow shaft 34 is rotatably connected to a rotating rod 36, and a stone-discharging cone bucket 37 is fixedly connected between the rotating rod 36 and the corresponding hollow tube 33. The height of the stone-discharging cone bucket 37 located at one end of the hollow tube 33 is lower than the height of the hollow shaft 34, so that when the stone is located in the stone-discharging cone bucket 37, it can slide smoothly into the hollow tube 33. A counterweight block 38 is fixedly connected to the hollow tube 33, and the counterweight block 38 is located between the end panel 11 and the annular fixing seat 14. With the cooperation of the counterweight block 38, the opening of the stone-discharging cone bucket 37 is always located directly above, so that the stone is effectively received, and the stone-discharging cone bucket 37 is densely provided with through holes (not shown in the figure) to prevent the sewage and sludge from being received during the process of the sewage entering the water filter cylinder 1;

[0052] A plurality of stone-moving plates 39 are fixedly connected between the turntables 31, a retaining ring 112 slidably connected to the free end of the hollow tube 33 is fixedly connected to the arc-shaped water filter plate 12, and a stone-discharging pipe 113 penetrating the corresponding end panel 11 is fixedly connected to the top of the retaining ring 112. During the rotation of the metal cage 3, the stones collected in the metal cage 3 are lifted by the internal plurality of stone-moving plates 39 and guided into the stone-discharging cone 37, and the stones are transferred to the hollow tube 33 for temporary storage through the inclined stone-discharging cone 37, until the metal cage 3 rotates to the highest position, the hollow tube 33 is communicated with the stone-discharging pipe 113 on the retaining ring 112, so that during the separation process, the stones can be automatically discharged from the water filter cylinder 1 at the same time, thereby improving the convenience of stone separation and removal.

[0053] Example 3: Please refer to Figure 2-Figure 4 , Figure 6 and Fig.12 As shown, the mud blocking plate 5 is slidably connected to the arc-shaped water filter plate 12, and the free side of the squeezing plate 42 is in sliding contact with the arc-shaped water filter plate 12 under the action of a spring 46, so as to squeeze and dehydrate the sludge. The sludge is blocked by the cooperation of a plurality of mud blocking plates 5 to prevent the squeezing plate 42 from pushing the sludge to move in the arc-shaped water filter plate 12, thereby reducing the dehydration efficiency and quality. One side of the mud blocking plate 5 passes through the arc-shaped water filter plate 12 and is fixedly connected with a linkage plate 51. Both sides of the linkage plate 51 are symmetrically fixedly connected with linkage rods 52 slidably connected to the arc-shaped water filter plate 12. A limiting plate 53 is fixedly connected to the linkage rod 52. A spring 2 54 is fixedly connected between the limiting plate 53 and the arc-shaped water filter plate 12. The sliding installation of the mud blocking plate 5 is realized by the cooperation of the linkage rod 52, the linkage plate 51 and the spring 2 54, so as to realize the squeezing treatment of sludge of different thicknesses in the water filter cylinder 1, thereby ensuring the dehydration effect of the sludge.

[0054] A guide wheel 25 abutting the end of the linkage rod 52 is fixedly connected to the rotating shaft 23, and a guide protrusion 26 is fixedly connected to the annular outer wall of the guide wheel 25 at each squeezing plate 42. In the process of shoveling the sludge after squeezing and dehydration, before the squeezing plate 42 contacts the mud blocking plate 5, the guide protrusion 26 on the guide wheel 25 first contacts the linkage rod 52 on both sides of the mud blocking plate 5, and driven by the linkage plate 51, forces one end of the mud blocking plate 5 to move completely to the inside of the side wall of the arc-shaped water filter plate 12, until the squeezing plate 42 successfully passes through the area of ​​the mud blocking plate 5, the guide protrusion 26 is separated from the linkage rod 52, and the mud blocking plate 5 is reset under the compression of the spring 2 54, so that the squeezing plate 42 can smoothly fit the arc-shaped water filter plate 12 to complete the mud removal process.

[0055] Example 4: Please refer to Figure 1-Figure 12 As shown, the present invention also proposes a working method of an environmentally friendly sewage circulation treatment system, comprising the following steps:

[0056] S1: Inject sewage into the water filter cylinder 1 through the liquid inlet 19, filter the sewage through the water filter holes 13 on the arc-shaped water filter plate 12, and retain the sludge and gravel in the sewage in the water filter cylinder 1;

[0057] S2: The motor 24 cooperates with the rotating shaft 23 to drive the rotating plate 21 to rotate, and the rotating plate 21 drives multiple metal cages 3 to rotate circumferentially in the water filter cylinder 1, and during the circumferential rotation, the rotating gear 35 is meshed with the inner gear ring 111 to synchronously rotate. During the rotation of the metal cage 3, when the plurality of U-shaped rods 32 on the annular outer wall of the rotating disk 31 contact the stones in the sludge, the U-shaped rods 32 in this area are squeezed and deformed, so that a large gap appears between the U-shaped rods 32 on both sides of the stones, thereby forcing the stones to squeeze into the metal cage 3;

[0058] S3: When the metal cage 3 rotates circumferentially, the corresponding extrusion plate 42 is driven to rotate. The free side of the extrusion plate 42 contacts the arc-shaped water filter plate 12 under the action of the spring 46, and the sludge is squeezed and dehydrated. In the process of rotation and extrusion, the multiple mud blocking plates 5 cooperate to prevent the extrusion plate 42 from pushing the sludge to move in the arc-shaped water filter plate 12. In the process of removing stones, the sludge is dehydrated synchronously.

[0059] S4: During the rotation of the metal cage 3, the multiple stone-moving plates 39 inside it rotate synchronously, lift the stones collected in the metal cage 3, and guide them into the stone-discharging cone bucket 37. The stones are transferred to the hollow tube 33 for temporary storage through the inclined stone-discharging cone bucket 37. After the metal cage 3 rotates to the highest position, the hollow tube 33 communicates with the stone-discharging pipe 113 on the retaining ring 112, and the separated stones are automatically discharged from the water filter cylinder 1;

[0060] S5: After the extrusion plate 42 moves from the arc-shaped water filter plate 12 to the arc-shaped cover plate 15, the compression elastic force of the spring 146 is released and cooperates with the mud pusher plate 43 to push the free side of the extrusion plate 42 to move to the area between the arc-shaped cover plate 15 and the arc-shaped water filter plate 12. The rotating plate 21 continues to rotate, and the extrusion plate 42 contacts the mud guide plate 17 and compresses the spring 146 again. In this process, a knocking vibration is formed to accelerate the separation of sewage in the sludge.

[0061] S6: After the sludge dehydration is completed, the motor 24 drives the rotating plate 21 to rotate in the opposite direction, and the rotating plate 21 drives the guide wheel 25 to rotate synchronously, and the free side of the squeezing plate 42 is fitted with the inner wall of the arc-shaped water filter plate 12 to perform a shoveling operation on the squeezing and dehydrated sludge, and before the squeezing plate 42 contacts the mud blocking plate 5, the guide protrusion 26 on the guide wheel 25 first contacts the linkage rod 52 on both sides of the mud blocking plate 5, and driven by the linkage plate 51, one end of the mud blocking plate 5 is forced to move completely to the inside of the side wall of the arc-shaped water filter plate 12, until the squeezing plate 42 successfully passes through the area of ​​the mud blocking plate 5, the guide protrusion 26 is separated from the linkage rod 52, and the mud blocking plate 5 is reset under the compression of the spring 2 54;

[0062] S7: After the squeezing plate 42 pushes the sludge to move above the mud guide plate 17, the mud pushing plate 43 moves on the squeezing plate 42 under the compression force of the spring 1 46, scrapes the sludge on the squeezing plate 42, makes it fall onto the mud guide plate 17, and is discharged through the mud outlet 18.
