Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a circulating biological contact oxidation reactor. Background Technology

[0002] With increasingly stringent environmental protection requirements, wastewater treatment has become a crucial aspect of environmental protection. Circulating biological contact oxidation reactors, as key equipment in wastewater treatment, have been widely applied in this field. Utilizing the principle of biological contact oxidation, microorganisms grow on a fixed bed to form a biofilm. Through contact between wastewater and the biofilm, pollutants in the wastewater are degraded and purified.

[0003] Currently, replacing the bed in existing circulating biological contact oxidation reactors is extremely inconvenient during maintenance. Since the bed is typically fixed inside the reactor, replacement often requires complex disassembly of multiple reactor components, resulting in cumbersome and time-consuming procedures. This not only increases maintenance costs but also leads to prolonged reactor downtime, impacting wastewater treatment efficiency. Therefore, we propose a circulating biological contact oxidation reactor. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4This invention proposes a circulating biological contact oxidation reactor, comprising a growth reaction zone 1, a transition cone zone 2 fixedly installed at the bottom of the growth reaction zone 1, a U-shaped connecting zone 3 fixedly installed at the bottom of the transition cone zone 2, a reflux zone 4 fixedly installed at the end of the U-shaped connecting zone 3 away from the transition cone zone 2, a straight channel zone 5 fixedly installed on the outer wall of the reflux zone 4, a lifting assembly 6 provided on the outer wall of the growth reaction zone 1, a mounting sieve plate 7 provided on the lifting assembly 6, a bed frame assembly 8 provided on the mounting sieve plate 7, the bed frame assembly 8 including a fixing block 81, the fixing block 81 fixedly connected to the bottom of the mounting sieve plate 7, and the inner wall of the fixing block 81 slidably connected to... There is a guide rail 82, an elastic metal sheet 83 is fixedly connected to the outer wall of the fixing block 81, a connecting plate 84 is fixedly connected to the bottom of the fixing block 81, a limit stop 85 is fixedly connected to one end of the guide rail 82, a toggle block 86 is fixedly connected to the other end of the guide rail 82, an installation plate 87 is snapped into the bottom of the installation sieve plate 7, a placement rod 88 is fixedly connected to the bottom of the installation plate 87, a bed body 89 is fixedly connected to the outer wall of the placement rod 88, and multiple sets of beds 89 are set on a set of placement rods 88. The bed body 89 serves as a carrier for biofilm attachment and growth, providing a suitable growth environment for microorganisms and facilitating the biological contact oxidation reaction.

[0028] In this invention, the end of the straight channel area 5 away from the backflow area 4 is fixedly installed on the outer wall of the growth reaction area 1. A limiting notch 821 is provided on the guide slide rail 82. The end of the elastic metal sheet 83 away from the fixing block 81 abuts against the inner wall of the limiting notch 821. The connecting plate 84 and the toggle block 86 are elastically connected by a compression spring. This structural design enables the guide slide rail 82 to be stably limited under normal conditions to prevent the mounting plate 87 from accidentally falling off, while the limiting can be easily released when adjustment is needed.

[0029] Furthermore, the lifting assembly 6 includes an electric cylinder base 61, the output end of which is fixedly connected to a lifting plate 62, and a guide lug 63 is fixedly connected to the outer wall of the growth reaction zone 1. The electric cylinder base 61 provides power for the lifting of the lifting plate 62, ensuring that the lifting process is smooth and controllable.

[0030] Furthermore, a guide rod 64 is slidably connected to the inner wall of the guide lug 63. The top of the guide rod 64 is fixedly connected to the bottom of the lifting plate 62. The guide rod 64 cooperates with the guide lug 63 to provide good guidance for the movement of the lifting plate 62, ensuring the stability and accuracy of its up and down movement.

[0031] Furthermore, a cover plate 65 is fixedly connected to the bottom of the lifting plate 62, and a connecting rod 66 is fixedly connected to the bottom of the cover plate 65. The bottom of the connecting rod 66 is fixedly connected to the top of the mounting screen plate 7, and the cover plate 65 can drive the mounting screen plate 7 to move synchronously through the connecting rod 66.

[0032] Furthermore, the bottom of the mounting screen plate 7 is provided with mounting blind holes 71, and the mounting plate 87 can be snapped into the mounting blind holes 71. There are multiple sets of mounting blind holes 71. The snap-fit ​​design of multiple sets of mounting blind holes 71 and mounting plate 87 facilitates the installation and fixation of mounting plate 87 in different positions and improves the assembly efficiency of the device.

[0033] Furthermore, a drive motor 9 is fixedly connected to the top of the reflux zone 4, and a rotating shaft 10 is fixedly connected to the output end of the drive motor 9. An agitator 11 is fixedly connected to the outer wall of the rotating shaft 10. The drive motor 9 drives the agitator 11 to rotate, so that the wastewater forms a circulation in the reactor, promotes full contact between the wastewater and the biofilm on the bed 89, and improves the reaction efficiency.

[0034] When the bed 89 needs to be replaced, the electric cylinder seat 61 is activated to move the lifting plate 62 upward, which in turn moves the cover plate 65 synchronously, separating it from the top of the growth reaction zone 1. The movement of the lifting plate 62 is guided by the guide slide rod 64. When the cover plate 65 moves upward, the connecting rod 66 moves the mounting sieve plate 7 upward, so that the bed frame assembly 8 leaves the growth reaction zone 1.

[0035] When the bed frame assembly 8 leaves the growth reaction zone 1, the elastic metal plate 83 is moved away from the limiting notch 821. Then, the actuating block 86 is pulled to move the guide rail 82, causing the limiting block 85 to leave the mounting plate 87 directly below it. At this time, the limiting state of the mounting plate 87 is released, making it easy to remove the mounting plate 87 and replace the bed 89. The operation is simple and convenient, without complicated disassembly steps, which greatly shortens the replacement time of the bed 89 and improves maintenance efficiency.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
