Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage regulating tank stirring device. Background Art

[0002] In today's industrial production, urban life, agricultural activities and other fields, a large amount of sewage is generated. The sewage regulating tank collects sewage from different periods, sources, water quality and water quantity, and performs preliminary homogenization and quantity adjustment to make its water quality and quantity relatively stable.

[0003] However, in sewage regulating tanks, due to the natural sedimentation of sewage and the interaction between various pollutants, sewage is prone to problems such as water stratification and solid precipitation accumulation, which not only occupies the effective volume of the regulating tank, but also may cause problems such as pipe blockage. At the same time, organic matter, oil and other substances in sewage may float on the water surface to form foam, affecting the water's reoxygenation capacity and the growth environment of microorganisms, leading to local water quality deterioration, and thus reducing the efficiency and effectiveness of subsequent sewage treatment.

[0004] Traditional solutions include regular manual cleaning of the sludge at the bottom of the pool and the foam on the surface, but this method is not only labor-intensive and costly, but also fails to evenly mix the sewage in the equalization tank, making it difficult to meet the requirements of modern sewage treatment. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a sewage regulating tank stirring device, including a sewage regulating tank, wherein a primary stirring device, a secondary stirring device and a receiving device are arranged in the sewage regulating tank;

[0006] The primary stirring device comprises an extension rod, a cross rod, a limiting rod, a cross plate and a bottom plate, and the lower surface of the cross rod is fixedly connected to the limiting rod;

[0007] The secondary stirring device comprises a reciprocating screw, a main sprocket threadedly connected to the reciprocating screw, a chain meshed with the main sprocket, a first sprocket of the chain, and a connecting shaft fixedly connected to the first sprocket and a stirring rod fixedly connected to the connecting shaft;

[0008] The receiving device comprises a frame, a receiving box fixedly connected to the frame, and an inclined plate fixedly connected to the side surface of the receiving box.

[0009] The technical solution adopted to solve the above technical problems is: the extension rod, the cross rod, the limit rod, the cross rod and the bottom plate can stir the sewage in the sewage regulating tank during the rotation, and the bottom plate can produce up and down displacement under the rotation of the reciprocating screw during the rotation, and the sewage is dynamically stirred during the displacement. The reciprocating screw can drive the main sprocket to rotate when rotating, and then the connecting shaft and the stirring rod rotate, so that the stirring rod stirs the sewage, making the sewage mixed more fully to avoid stratification and bottom sedimentation, reducing the workload of manual cleaning, and the receiving device can collect the floating foam on the surface of the sewage in a centralized manner.

[0010] Furthermore, a base frame is provided on the upper surface of the sewage regulating tank, a first motor is fixedly connected to the upper surface of the base frame, a rotating shaft is fixedly connected to the output end of the first motor, a frustum is fixedly connected to the side surface of the rotating shaft, and a guide cylinder is fixedly connected to the side surface of the rotating shaft.

[0011] Through the above technical solution, the first motor can provide power for the rotation of the device when it is started, and the round table is used to install the second motor.

[0012] Furthermore, the upper surface of the extension rod is fixedly connected to the truncated table, the upper surface of the truncated table is fixedly connected to a second motor, the output end of the second motor is fixedly connected to the reciprocating screw, and one end of the cross rod is fixedly connected to the guide cylinder.

[0013] Through the above technical scheme, after the second motor is energized, the reciprocating screw can rotate, thereby causing the base plate and the mounting frame to move back and forth up and down, and the main sprocket to rotate, thereby causing the first sprocket to drive the stirring rod to rotate, stirring the sewage to avoid sewage stratification or sedimentation at the bottom.

[0014] Furthermore, a sleeve 1 is threadedly connected to the side surface of the reciprocating screw, the side surface of the sleeve 1 is fixedly connected to the bottom plate, the side surface of the sleeve 1 is fixedly connected to a limit plate, and the side surface of the limit plate is in contact with the limit rod.

[0015] Through the above technical solution, the limit plate and the limit rod cooperate to guide the up and down displacement of the sleeve 1, so that the sleeve 1 can produce up and down reciprocating displacement on the reciprocating screw to avoid rotating with the rotation of the reciprocating screw.

[0016] Furthermore, a connecting plate is fixedly connected to the upper surface of the base plate, a second sleeve is fixedly connected to the side surface of the connecting plate, and a side surface of the reciprocating screw is threadedly connected to the second sleeve.

[0017] Through the above technical solution, the sleeve 1, the bottom plate, the connecting plate and the sleeve 2 are connected together, so that the bidirectional screw drives the bottom plate and the connecting plate to move up and down during rotation.

[0019] Through the above technical solution, the mounting frame is used to install the frame when the receiving box is installed, and the limit block supports the lower end of the frame to limit the installation of the frame.

[0020] Furthermore, a plurality of reserved holes are penetrated through the lower surface of the receiving box, a scraper is movably connected to the side surface of the base plate, a fixed block is fixedly connected to the side surface of the scraper, a bolt is threadedly connected to the side surface of the fixed block, and the side surface of the bolt is threadedly connected to the base plate.

[0021] Through the above technical scheme, the sewage entering the receiving box can leak into the sewage regulating tank from the reserved hole. When the receiving box is removed to clean the floating foam and debris inside, the leakage of sewage can effectively reduce the overall weight. The reciprocating screw drives the scraper to move up and down during rotation, and the scraper scrapes off the debris attached to the inner wall of the sewage regulating tank.

[0022] Furthermore, a guardrail is provided on the upper surface of the base frame, and a ladder is provided on the side surface of the base frame.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) The truncated table, extension rod, cross bar, cross plate, bottom plate and mounting frame rotate synchronously, so that the sewage at different depths in the sewage regulating tank can be stirred to fully avoid stratification and sedimentation of the sewage;

[0025] (2) The bottom plate, the connecting plate and the mounting frame rotate around the center of the rotating shaft and can generate up and down displacement under the action of the second motor and the reciprocating screw. The sewage is dynamically stirred during the up and down reciprocating displacement. The scraper connected to the bottom plate can scrape off the attachments on the side inner wall of the sewage regulating tank during the up and down displacement. The reciprocating screw can rotate the main sprocket and then rotate the stirring rod to stir the sewage, so that the sewage is fully and evenly mixed.

[0026] (3) When the mounting frame moves up and down, it will drive the inclined plate of the receiving box installed on the mounting frame to continuously enter the sewage, so that the receiving box can receive the floating foam and debris above the sewage, reducing the pressure of manual cleaning.

[0038] like Figure 1-Figure 9 As shown, a sewage regulating tank stirring device of this embodiment includes a sewage regulating tank 1, in which a primary stirring device, a secondary stirring device and a receiving device are arranged.

[0039] A base frame 2 is provided on the upper surface of the sewage regulating tank 1, and a first motor 3 is fixedly connected to the upper surface of the base frame 2. The first motor 3 is electrically connected to an external power supply. It is known to those skilled in the art that the first motor 3 can drive the rotating shaft 4, the table 5 and the guide cylinder 6 to rotate after being energized. The output end of the first motor 3 is fixedly connected to the rotating shaft 4, the table 5 is fixedly connected to the side surface of the rotating shaft 4, and the guide cylinder 6 is fixedly connected to the side surface of the rotating shaft 4.

[0040] The primary stirring device includes an extension rod 7, a cross rod 8, a limit rod 13, a cross plate 14 and a bottom plate 121. The lower surface of the cross rod 8 is fixedly connected to the limit rod 13. When the first motor 3 drives the truncated table 5 and the guide cylinder 6 to rotate, it can drive the primary stirring device to rotate, so that the extension rod 7, the cross rod 8, the limit rod 13, the cross plate 14 and the bottom plate 121 stir the sewage in the sewage regulating tank 1 during rotation to avoid sewage stratification or precipitation at the bottom.

[0041] The upper surface of the extension rod 7 is fixedly connected to the truncated table 5, and the upper surface of the truncated table 5 is fixedly connected with a second motor 9. It is prior art that the second motor 9 is electrically connected to an external power supply. Those skilled in the art know that the output end of the second motor 9 is fixedly connected to the reciprocating screw 10. When the second motor 9 is started, it can drive the reciprocating screw 10 to rotate, thereby causing the sleeve 11 and the sleeve 2 16 to reciprocate up and down on the reciprocating screw 10. During the displacement, the bottom plate 121 is moved up and down to dynamically stir the sewage, so that the sewage is mixed more evenly and the sewage at the bottom can also be stirred.

[0042] One end of the cross bar 8 is fixedly connected to the guide cylinder 6, the side surface of the reciprocating screw 10 is threadedly connected with a sleeve 11, the side surface of the sleeve 11 is fixedly connected to the bottom plate 121, the side surface of the sleeve 11 is fixedly connected with a limit plate 12, the side surface of the limit plate 12 is in contact with the limit rod 13, the limit plate 12 and the limit rod 13 cooperate to guide the displacement of the sleeve 11, the upper surface of the bottom plate 121 is fixedly connected with a connecting plate 15, the side surface of the connecting plate 15 is fixedly connected with a sleeve 2 16, and the side surface of the reciprocating screw 10 is threadedly connected with the sleeve 2 16.

[0043] The secondary stirring device includes a reciprocating screw 10, a main sprocket 19 threadedly connected to the reciprocating screw 10, a chain 20 meshing with the main sprocket 19, a first sprocket 21 with the chain 20, and a connecting shaft 22 fixedly connected to the first sprocket 21 and a stirring rod 23 fixedly connected to the connecting shaft 22. When the reciprocating screw 10 rotates, the main sprocket 19 rotates, and the main sprocket 19 transmits power to the chain 20. When the chain 20 rotates, the first sprocket 21 rotates, and then the stirring rod 23 rotates, so that the stirring rod 23 stirs the sewage during rotation to make the sewage mixed more evenly.

[0044] The receiving device includes a frame 27, a receiving box 28 fixedly connected to the frame 27, and an inclined plate 30 fixedly connected to the side surface of the receiving box 28. The side surface of the sleeve 16 is fixedly connected with a mounting frame 17, and the side surface of the mounting frame 17 is fixedly connected with a limiting block 18. The side inner wall of the frame 27 contacts the mounting frame 17, and the lower surface of the frame 27 contacts the limiting block 18. A plurality of reserved holes 29 are penetrated on the lower surface of the receiving box 28. The mounting frame 17 drives the receiving box 28 to move up and down, so that the inclined plate 30 continuously enters the sewage to salvage floating foam and debris on the surface of the sewage. The floating foam and debris are collected by the receiving box 28 for easy removal and cleaning later.

[0045] The side surface of the bottom plate 121 is movably connected with a scraper 24, which moves with the displacement of the bottom plate 121, and scrapes off the debris attached to the side inner wall of the sewage regulating tank 1 during the up and down reciprocating displacement.

The side surface of the bolt 26 is threadedly connected to the bottom plate 121, and the scraper 24 and the bottom plate 121 can be connected together through the fixing block 25 and the bolt 26. A guardrail 31 is provided on the upper surface of the base frame 2, and a ladder 32 is provided on the side surface of the base frame 2. The top of the base frame 2 can be stepped on and walked by people, and the guardrail 31 protects both sides of the walking people to prevent people from falling into the sewage regulating tank 1.

[0046] The working principle of this embodiment is as follows: when it is necessary to stir the sewage in the sewage regulating tank 1, the power is turned on to start the first motor 3 so that the whole rotates inside the sewage regulating tank 1 to stir the sewage. At this time, when the second motor 9 is started, the reciprocating screw 10 rotates. During the rotation of the reciprocating screw 10, the sleeve 11 and the sleeve 2 16 are displaced up and down on the reciprocating screw 10, so that the bottom plate 121, the connecting plate 15 and the mounting frame 17 are displaced up and down, and the sewage at different depths in the sewage regulating tank 1 is stirred, and the scraper 24 is displaced up and down accordingly to scrape the impurities attached to the side inner wall of the sewage regulating tank 1, and the reciprocating screw 10 When rotating, it will drive the main sprocket 19 to rotate, and transmit power to the chain 20. The chain 20 drives the first sprocket 21 to rotate, and then the stirring rod 23 rotates to dynamically stir the sewage, so that the sewage is stirred more evenly, avoiding sewage stratification or sedimentation at the bottom. When the mounting frame 17 moves up and down, one end of the inclined plate 20 of the receiving box 28 installed on the mounting frame 17 will continuously enter the sewage, so that floating objects and debris on the surface of the sewage enter the receiving box 28. When there are too many debris and floating objects inside, the receiving box 28 can be removed to clean up the debris and floating objects inside, reducing the pressure of subsequent manual cleaning.

[0047] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
