Description

Technical Field

[0001] The invention relates to the technical field of microbial pollution control, and in particular to an environmentally friendly microbial sewage treatment device. Background Art

[0002] Porous suspended ball biological filler is a new type of microbial carrier, which is commonly used in microbial treatment of sewage. It is generally a spherical structure with a hollow surface. The fillers are installed inside the sphere and then suspended in water or on the water surface using its material properties, allowing the sewage to react with the filler and quickly generate microorganisms.

[0003] As proposed in the background technology of a Chinese patent on a salvage claw for a suspended ball biological filler, the suspended ball biological filler immersed in sewage needs to be manually recovered, and the interference between the spherical shape of the suspended ball and the sewage environment will increase the difficulty of salvage, and further, it will affect the replacement or filling efficiency of the filler in the suspended matter. Summary of the invention

[0004] The invention provides an environmentally friendly microbial sewage treatment device, which can quickly separate the suspended balls from the sewage and open the filling port to quickly and efficiently replace the filler inside the suspender.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An environmentally friendly microbial sewage treatment device comprises a floating stator that can be immersed in a sewage pool, a swing arm is rotatably mounted on the floating stator, a suspension ball is fixedly mounted on the free end of the swing arm, a filling port is opened on the outer wall of the suspension ball, a hemispherical expansion cover is rotatably mounted on the outer wall of the suspension ball, and the expansion cover covers the suspension ball but does not block the hollow part of the suspension ball;

[0007] The suspended ball has two spatial staying states:

[0008] In the first stop state, when the suspension ball contacts the sewage, the expansion cover blocks the filling port but does not interfere with the contact between other hollow parts of the suspension ball and the sewage;

[0009] In the second stay state, when the suspension ball rotates to be separated from the sewage, the expansion cover releases the blockage of the filling port, and after the rotation, the opening direction or position of the filling port is not sufficient to allow the internal filler to escape.

[0010] Optionally, the suspended ball includes a positioning body and an open body, both of which are hemispherical, and both are provided with hollow grooves, the loading port is opened on the arc end surface of the open body, the loading port has a perpendicular bisector L, and the positioning body and the open body have a common diameter R, and the perpendicular bisector L coincides with the common diameter R.

[0011] Optionally, flanges are installed on the outer walls of the ends of the opposite surfaces of the positioning body and the open body. The flanges are adhesively fixed together by glue. The two flanges are combined into a common part. Two symmetrically arranged notches are formed in the common part. A pin shaft is fixedly installed on the inner wall of the notch. A bush sleeving the outer wall of the pin shaft is fixedly installed on the outer wall of the expansion cover. The rotation axis Z of the bush and the expansion cover is perpendicular to and intersects the common diameter R at the center of the floating ball.

[0012] Optionally, a positioning rod is fixedly installed on the inner wall of the positioning body. An assembly rod is sleeved on the outer wall of the positioning rod. A spike part is arranged at the end of the assembly rod. The axis I of the assembly rod coincides with the common diameter R.

[0013] Optionally, there is an interference fit relationship between the inner wall of the assembly rod and the inner wall of the positioning rod.

[0014] Optionally, an internal thread is formed on the inner wall of the assembly rod, and an external thread is formed on the outer wall of the positioning rod. There is a spiral fit relationship between the internal thread and the external thread.

[0015] Optionally, two bearing seats are fixedly installed at the free end of the swing arm. The two bearing seats correspond to and are fixed to the two pin shafts one by one. An assembly shaft also penetrates and rotates on the outer wall of the bearing seat. One end of the assembly shaft is fixedly connected to the bush. A gear is fixedly installed at the end of one of the assembly shafts. An arc-shaped rack is fixedly installed on the top of the floating stator. When the swing arm rotates, the gear can be meshed with the arc-shaped rack. A reset device for assisting the expansion cover to reset and restricting the expansion cover to stay in the first stop state without external force is also included.

[0016] Optionally, the reset device includes a spring seat fixedly installed on the other assembly shaft. A torsion spring is fixedly installed between the outer wall of the bearing seat and the outer wall of the spring seat. The torsion spring is sleeved on the outer wall of the assembly shaft. When the floating ball is in the first stop state, the torsion spring makes the expansion cover continuously block the loading port.

[0017] Optionally, a rocker arm is fixedly installed at the end of the swing arm away from the floating ball. The intersection point of the swing arm and the rocker arm is the rotation point. An orifice plate is slidably installed on the inner wall of the floating stator. An electric telescopic rod for controlling the up and down displacement of the orifice plate is fixedly installed on the inner top of the floating stator. The bottom of the orifice plate abuts against the end of the rocker arm. When the orifice plate moves downward, the rocker arm and the floating device can be rotated.

[0018] Optionally, multiple layers of gradually shrinking through holes are formed on the outer wall of the expansion cover. The diameters of the through holes are all smaller than the loading port.

[0019] The present invention provides an environmentally friendly microbial sewage treatment device. By restricting the rotation of the floating balls, they can not only float on the water surface, but also be submerged below the sewage liquid level, and can be separated from the sewage. When separated from the sewage surface, the expansion cover can also release the restriction on the filling port, facilitating the staff to quickly and efficiently replace, wash or retrieve the fillers inside the floating balls through the filling port. When the floating balls are submerged or floating, the expansion cover will not interfere with the floating balls, enabling them to normally generate microorganisms, treat sewage, and adsorb suspended substances.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] 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.

[0030] See also Figures 1 to 8 The present invention provides an environmentally friendly microbial sewage treatment device, comprising a floating stator 11 that can be immersed in a sewage pool, a swing arm 14 is rotatably mounted on the floating stator 11, a suspension ball is fixedly mounted on the free end of the swing arm 14, a filling port 3 is opened on the outer wall of the suspension ball, a hemispherical expansion cover 4 is rotatably mounted on the outer wall of the suspension ball, and the expansion cover 4 covers the suspension ball but does not block the hollow part of the suspension ball.

[0031] The suspended ball has two spatial stay states:

[0032] In the first stay state, when the suspension ball contacts the sewage, the expansion cover 4 blocks the filling port 3 but does not interfere with the contact between other hollow parts of the suspension ball and the sewage.

[0033] In the second stay state, when the suspension ball rotates to be separated from the sewage, the expansion cover 4 releases the blockage of the filling port 3, and the opening direction or position of the filling port 3 after rotation is not sufficient to allow the internal filler to escape.

[0034] In order to facilitate the collection or salvage of the suspended ball, its rotation is restricted so that it can be suspended on the water surface, immersed below the sewage surface, and separated from the sewage. When separated from the sewage surface, the expansion cover 4 can also release the restriction on the filling port 3, so that the staff can quickly and efficiently replace, rinse or salvage the filler inside the suspended ball through the filling port 3. When the suspended ball is immersed or floating, the expansion cover 4 will not interfere with the suspended ball, so that it can normally produce microorganisms and treat sewage and adsorb suspended matter.

[0035] In one of the preferred embodiments, the suspension ball includes a positioning body 1 and an open body 2. Both the positioning body 1 and the open body 2 are hemispherical, and both the positioning body 1 and the open body 2 are provided with hollow grooves. The filling port 3 is provided on the arc end surface of the open body 2. The filling port 3 has a midline L. There is a common diameter R between the positioning body 1 and the open body 2. The midline L coincides with the common diameter R. Please refer to Figure 1 , Figures 4 to 8 ,in Figure 1The positioning body 1 and the open body 2 shown are symmetrically distributed left and right. Due to the coincidence of the vertical bisector L and the common diameter R, the loading port 3 is opened on the far left or far right. Therefore, when the swing arm 14 rotates upward, the opening of the loading port 3 can also rotate upward to prevent the filling inside the suspension ball from escaping.

[0036] Based on the suspension ball embodiment, flange portions are installed on the outer end walls of the opposite faces of the positioning body 1 and the open body 2. The flange portions are adhesively fixed together with glue. The two flange portions are combined into a common part, and two symmetrically arranged notches 6 are formed in the common part. A pin shaft 7 is fixedly installed on the inner wall of the notch 6. A bushing sleeving the outer wall of the pin shaft 7 is fixedly installed on the outer wall of the extension cover 4. The rotation axis Z of the bushing and the extension cover 4 is perpendicular to the common diameter R and intersects at the center of the suspension ball. Please refer to Figures 4 to 8 , this embodiment shows how the extension cover 4 forms a rotational connection relationship with the positioning body 1 and the open body 2, and defines the rotation axis of the extension cover 4. Specifically, in this embodiment, through the fitting of the two flange portions and their relatively large areas, the positioning body 1 and the open body 2 can be fixed by gluing, so that the positioning body 1 and the open body 2 can form a relatively scientific and reasonable sphere, which is convenient for the extension cover 4 to cover and be rotatably installed on the outer wall of the suspension ball.

[0037] Based on the suspension ball embodiment, a positioning rod 16 is fixedly installed on the inner wall of the positioning body 1. An assembly rod 17 is sleeved on the outer wall of the positioning rod 16. A spike portion is provided at the end of the assembly rod 17. The axis I of the assembly rod 17 coincides with the common diameter R. By providing the assembly rod 17, the filling can be punctured and installed on the outer wall of the assembly rod 17, which can not only fix and limit the filling, but also, due to the coincidence of the axis I of the assembly rod 17 and the R of the common diameter, enable the spike portion of the assembly rod 17 to face the loading port 3, facilitating the subsequent process of taking out or replacing the filling and also preventing the filling from escaping.

[0038] The following presents two ways to limit the assembly rod 17.

[0039] First, there is an interference fit relationship between the inner wall of the assembly rod 17 and the inner wall of the positioning rod 16. The positioning rod 16 can be a cylinder, and the inner wall of the assembly rod 17 has an interference portion, so that an interference fit can be generated when the assembly rod 17 and the positioning rod 16 are inserted.

[0040] Second, an internal thread is provided on the inner wall of the assembly rod 17, and an external thread is provided on the outer wall of the positioning rod 16. There is a screw thread fit relationship between the internal thread and the external thread.

[0041] Further, two bearing seats 5 are fixedly installed at the free end of the swing arm 14. The two bearing seats 5 correspond to and are fixed to the two pin shafts 7 one by one. An assembly shaft 20 also penetrates and rotates on the outer wall of the bearing seat 5. One end of the assembly shaft 20 is fixedly connected to a bushing. A gear 8 is fixedly installed at the end of one of the assembly shafts 20. An arc-shaped rack 9 is fixedly installed at the top of the floating stator 11. When the swing arm 14 rotates, the gear 8 can be meshed with the arc-shaped rack 9. There is also a reset device for assisting the expansion cover 4 to reset and restricting the expansion cover 4 from staying in the first stop state without external force. Please refer to Figures 4 to 8 , through the cooperation between the gear 8 and the arc-shaped rack 9, when the suspension ball rotates from the first stop state to the second stop state, the expansion cover 4 can rotate relative to the suspension ball, so that the expansion cover 4 releases the blockage of the loading port 3, facilitating the staff to clean, replace or rinse the filler inside the suspension ball. On the contrary, during the process of the suspension ball changing from the second stop state to the first stop state, the cooperation between the arc-shaped rack 9 and the gear 8 will cause the expansion cover 4 to block the loading port 3 again. However, by setting the reset device, the expansion cover 4 can effectively maintain the blocking state during the process or in the first stop state.

[0042] Further, please refer to Figure 8 , the reset device includes a spring seat 18 fixedly installed on the other assembly shaft 20. A torsion spring 19 is fixedly installed between the outer wall of the bearing seat 5 and the outer wall of the spring seat 18. The torsion spring 19 is sleeved on the outer wall of the assembly shaft 20. When the suspension ball is in the first stop state, the torsion spring 19 makes the expansion cover 4 continuously block the loading port 3.

[0043] In a more preferred embodiment, a rocker arm 15 is fixedly installed at the end of the swing arm 14 away from the suspension ball. The intersection point of the swing arm 14 and the rocker arm 15 is the rotation point. A hole plate 13 is slidably installed on the inner wall of the floating stator 11. An electric telescopic rod 12 for controlling the up and down displacement of the hole plate 13 is fixedly installed at the inner top of the floating stator 11. The bottom of the hole plate 13 abuts against the end of the rocker arm 15. When the hole plate 13 moves downward, the rocker arm 15 and the suspension device can be rotated. Please refer to Figures 1 to 3 , by setting the up and down displacement of the hole plate 13, when it moves downward, the swing arm 14 can be rotated upward. When the restriction on the rocker arm 15 is released when it moves upward, the swing arm 14 can return to the first stop state under the action of the gravity of the suspension ball, so that the hole plate 13 can form an abutment against the rocker arm 15 again.

[0044] Even further, please refer to Figure 6 , a multi-layered gradually shrinking through hole is opened on the outer wall of the expansion cover 4, and the caliber of the through hole is smaller than that of the loading port 3.

[0045] With the above structure or components, the floating ball can be quickly separated from the sewage, and at the same time, the filling port 3 is opened to facilitate the quick replacement of the filler inside the floating device.

[0046] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be processed without doubt according to the existing technical common sense. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
