Biological packing assembly

Abstract

This utility model discloses a biological packing assembly, including an upper bearing, a lower bearing, a rotating shaft, and multiple packing module assemblies. The upper and lower bearings are respectively fitted onto the upper and lower ends of the rotating shaft. The multiple packing module assemblies are evenly distributed around the axis of the rotating shaft. Each packing module assembly includes multiple packing modules, which are arranged in the same vertical row. The packing modules are cuboid in shape and vertically arranged. The first end of the packing module is connected to the side wall of the rotating shaft. Each packing module assembly contains biological packing. In this application, the static packing in the prior art is replaced with a rotatable mechanical structure. The packing is driven to rotate by water flow, which enhances the gas-liquid-solid three-phase contact. The rotation of the biological packing assembly generates centrifugal force, which promotes biofilm renewal and pollutant diffusion. Furthermore, the shear force during rotation can automatically peel off the aging biofilm, reducing the risk of clogging.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a biological packing assembly. Background Technology

[0002] Biological packing components are key components used in environmental protection projects such as water treatment and waste gas treatment. They are mainly used to provide a carrier for microorganisms to attach and grow, so as to promote the biodegradation of pollutants.

[0003] The existing bio-filler assemblies have the following problems:

[0004] 1. Because the biological packing components in existing technologies are fixed, the effects of biofilm renewal and pollutant diffusion are not good;

[0005] 2. Furthermore, when treating high-concentration organic wastewater, the wastewater may clog the biological packing components.

[0006] Therefore, it is necessary to develop a biological filler component to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to design a biological packing component to solve the above-mentioned problems.

[0008] This utility model achieves the above objectives through the following technical solutions:

[0009] Biological packing assembly, including:

[0010] Upper bearing; the upper bearing is fixedly installed at the top of the water flow channel;

[0011] Lower bearing; the lower bearing is fixedly installed at the bottom of the water flow channel;

[0012] The shaft is vertically oriented, with upper and lower bearings respectively fitted onto its upper and lower ends.

[0013] Multiple packing module components; multiple packing module components are evenly distributed around the axis of the rotating shaft. Each packing module component includes multiple packing modules. The multiple packing modules in each packing module component are arranged in the same vertical row. The packing modules are rectangular in shape and vertically arranged. The first end of the packing module is connected to the side wall of the rotating shaft. Each packing module component is equipped with biological packing.

[0014] Specifically, the packing module includes a mounting frame, a first packing block, a second packing block, and a third packing block. The mounting frame is a hollow cuboid frame structure. The first end of the mounting frame is connected to the side wall of the rotating shaft, and the second end of the mounting frame is provided with an installation port. Water inlets are provided on both sides of the mounting frame. The first, second, and third packing blocks are arranged horizontally side by side. The second packing block is located between the first and third packing blocks. The first and third packing blocks are located near the water inlets on both sides. The first, second, and third packing blocks are installed inside the mounting frame through the installation port. Honeycomb-shaped biological packing is provided inside the first, second, and third packing blocks, and the honeycomb-shaped openings of the honeycomb-shaped biological packing are arranged horizontally.

[0015] Specifically, the honeycomb openings of the first and third packing blocks are the same size, while the honeycomb opening of the second packing block is smaller than that of the first and third packing blocks.

[0016] Specifically, three sliding grooves are arranged side by side at the top and bottom of the mounting frame. Correspondingly, sliders are provided at the top and bottom of the first packing block, the second packing block, and the third packing block. The top sliders of the first packing block, the second packing block, and the third packing block are slidably placed in the three sliding grooves at the top of the mounting frame, and the bottom sliders of the first packing block, the second packing block, and the third packing block are slidably placed in the three sliding grooves at the bottom of the mounting frame.

[0017] Furthermore, the filler module also includes a bonding plate, the first end of which is connected to the first end of the mounting bracket, and the second end of which is formed into an arc-shaped surface with the same diameter as the diameter of the rotating shaft. The second end of the mounting plate is bonded to the side wall of the rotating shaft.

The first end of the mounting plate is installed at the bottom center of the arc-shaped surface, and the second end of the mounting plate is inserted into the mounting groove.

[0019] Specifically, the packing module also includes a screw and a nut. The mounting plate has first fixing holes horizontally arranged above and below. Correspondingly, second fixing holes are opened above and below the rotating shaft. The first end of the second fixing hole is the first mounting hole, and the second end of the second fixing hole is the second mounting hole. After the screw passes through the second fixing hole and the first fixing hole, it is threaded with the nut. The head of the screw is placed in the first mounting hole, and the nut is placed in the second mounting hole.

[0020] The beneficial effects of this utility model are as follows:

[0021] In this application, the static packing material in the prior art is replaced with a rotatable mechanical structure. The packing material is driven to rotate by water flow, which enhances the gas-liquid-solid three-phase contact. When the biological packing material component rotates, it generates centrifugal force, which promotes biofilm renewal and pollutant diffusion. Furthermore, during the rotation process, shear force can automatically peel off the aging biofilm, reducing the risk of clogging. Attached Figure Description

[0034] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 and 2 As shown, the biological packing assembly includes:

[0036] Upper bearing 3; Upper bearing 3 is fixedly installed at the top of the water flow channel;

[0037] Lower bearing 4; Lower bearing 4 is fixedly installed at the bottom of the water flow channel;

[0038] Rotating shaft 1; Rotating shaft 1 is vertically arranged, with upper bearing 3 and lower bearing 4 respectively fitted onto the upper and lower ends of rotating shaft 1;

[0039] Four packing modules 2 are evenly distributed around the axis of the rotating shaft 1. Each packing module 2 includes four packing modules 2, which are arranged in the same vertical row. The packing modules 2 are rectangular in shape and are vertically arranged. The first end of the packing module 2 is connected to the side wall of the rotating shaft 1. Each packing module 2 contains biological packing.

[0040] like Figure 4 and 5 As shown, the packing module 2 includes a mounting frame 5, a first packing block 6, a second packing block 7, and a third packing block 8. The mounting frame 5 is a hollow cuboid frame structure. The first end of the mounting frame 5 is connected to the side wall of the rotating shaft 1. The second end of the mounting frame 5 is provided with an installation port 18. Water inlets 19 are provided on both sides of the mounting frame 5. The first packing block 6, the second packing block 7, and the third packing block 8 are arranged horizontally side by side. The second packing block 7 is located between the first packing block 6 and the third packing block 8. The first packing block 6 and the third packing block 8 are respectively located near the water inlets 19 on both sides. The first packing block 6, the second packing block 7, and the third packing block 8 are installed in the mounting frame 5 through the installation port 18. Honeycomb-shaped biological packing is provided in the first packing block 6, the second packing block 7, and the third packing block 8. The honeycomb-shaped openings of the honeycomb-shaped biological packing are arranged horizontally.

[0041] In some embodiments, the honeycomb openings of the first packing block 6 and the third packing block 8 are of the same size, while the honeycomb openings of the second packing block 7 are smaller than those of the first packing block 6 and the third packing block 8. This smaller honeycomb opening in the second packing block 7 allows the second packing block 7, the first packing block 6, and the third packing block 8 to adapt to the growth needs of different microbial communities. In this embodiment, the outer first packing block 6 and the third packing block 8 are suitable for rapidly growing heterotrophic bacteria, while the micropores of the inner second packing block 7 enrich the micropores for slowly growing nitrifying bacteria.

[0042] like Figure 4 and 5 As shown, three sliding grooves 9 are arranged side by side at the top and bottom of the mounting frame 5. Correspondingly, sliders 10 are provided at the top and bottom of the first packing block 6, the second packing block 7, and the third packing block 8. The top sliders 10 of the first packing block 6, the second packing block 7, and the third packing block 8 are slidably placed in the three sliding grooves 9 at the top of the mounting frame 5, and the bottom sliders 10 of the first packing block 6, the second packing block 7, and the third packing block 8 are slidably placed in the three sliding grooves 9 at the bottom of the mounting frame 5. During operation, the first packing block 6, the second packing block 7, and the third packing block 8 slide into the sliding grooves 9 of the mounting opening 18 of the mounting frame 5 until they reach the bottom of the sliding grooves 9 to complete the installation of the first packing block 6, the second packing block 7, and the third packing block 8. Similarly, the disassembly is performed in the reverse direction.

[0043] like Figure 3 and 5As shown, the filler module 2 also includes a bonding plate 17. The first end of the mounting plate 13 is connected to the first end of the mounting bracket 5, and the second end of the mounting plate 13 is formed into an arc-shaped surface with the same diameter as the diameter of the rotating shaft 1. The second end of the mounting plate 13 is bonded to the side wall of the rotating shaft 1. The bonding plate 17 can ensure that the end of the mounting bracket 5 is tightly bonded to the side wall of the rotating shaft 1, making the mounting bracket 5 stable and less prone to shaking.

[0044] like Figure 3 As shown, the filler module 2 also includes a mounting plate 13, and a mounting groove 11 is provided on the side wall of the rotating shaft 1. The first end of the mounting plate 13 is installed at the bottom center of the arc surface, and the second end of the mounting plate 13 is inserted into the mounting groove 11.

[0045] like Figure 3 As shown, the packing module 2 also includes a screw 15 and a nut 16. First fixing holes are horizontally arranged above and below the mounting plate 13. Correspondingly, second fixing holes 20 are formed above and below the rotating shaft 1. The outer side of the first end of the second fixing hole 20 is a first mounting hole 12, and the outer side of the second end of the second fixing hole 20 is a second mounting hole 14. The screw 15 passes through the second fixing hole 20 and the first fixing hole and then engages with the nut 16 threadedly. The head of the screw 15 is placed inside the first mounting hole 12, and the nut 16 is placed inside the second mounting hole 14. During operation, the mounting plate 13 is inserted into the mounting groove 11, and then the screw 15 is inserted from one side of the first mounting hole 12. The screw 15 passes through part of the second fixing hole 20, the first fixing hole, and another part of the second fixing hole 20 before exiting through the second mounting hole 14. A nut is placed in the second mounting hole 14 and engages with the screw 15 threadedly, thereby locking the mounting position of the mounting plate 13.

[0046] Working principle: During operation, sewage flows towards one side of the biological packing module 2, flushing the packing module 2. At the same time, sewage enters the first packing block 6, the second packing block 7, and the third packing block 8 through the honeycomb openings. The first packing block 6, the second packing block 7, and the third packing block 8 create a stable attachment environment for microorganisms (such as bacteria and fungi), forming a biofilm, thereby enhancing the decomposition efficiency of organic matter in sewage. Meanwhile, the water flow drives the four packing modules 2 and the rotating shaft 1 to rotate. The rotation of the biological packing module generates centrifugal force, promoting biofilm renewal and pollutant diffusion. Furthermore, during the rotation, shear force can automatically peel off the aging biofilm, reducing the risk of clogging.

[0047] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
