[0002] Chemical wastewater treatment refers to the process of treating wastewater generated during chemical plant production to meet discharge standards or for recycling. Chemical wastewater treatment involves multiple stages and methods aimed at removing pollutants, including suspended particles, fine fibers, grease, suspended solids, and toxic and harmful substances such as recalcitrant organic matter. The treatment process includes pretreatment, biological treatment, and advanced treatment steps to ensure that the wastewater meets national discharge standards or higher standards for recycling. Aeration devices are required in chemical wastewater treatment, thus necessitating a circulating aeration device for chemical wastewater treatment to meet the needs of users.

[0003] Most circulating aeration devices for chemical wastewater treatment on the market require disassembly and maintenance for long-term use. This makes it inconvenient for operators to operate the device and increases their workload. Utility Model Content

[0029] Example 1: Refer to Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a circulating aeration device for chemical wastewater treatment. It can solve the problem that most circulating aeration devices for chemical wastewater treatment on the market need to be disassembled and maintained for a long time. When the operator disassembles and installs the aeration device, it is inconvenient for the operator to operate and increases the labor intensity of the operator. It includes a wastewater tank body 1, which includes a base 101. The base 101 is installed at the bottom of the inside of the wastewater tank body 1. An aeration pipe 102 is provided at the top of the base 101. A connecting pipe 103 is installed on the outer wall of the aeration pipe 102. An aeration nozzle 104 is installed at the top of the aeration pipe 102. An external connecting pipe 105 is installed on the outer wall of the aeration pipe 102.

[0030] The installation and disassembly mechanism 2 includes a fixed base 201, which is installed on the top of the base 101. A first mounting base 202 is installed on the top of the fixed base 201, and a second mounting base 203 is hinged to the top of the first mounting base 202. A first mounting plate 204 is installed on the end of the second mounting base 203 away from the first mounting base 202, and a limit component 205 is installed inside the first mounting plate 204. A second mounting plate 206 is installed on the end of the first mounting base 202 away from the second mounting base 203, and a limit hole 2063 is opened inside the second mounting plate 206. The first mounting base 202 and the second mounting base 203 are the same size and structure, and the first mounting base 202 and the second mounting base 203 are semi-circular in shape.

[0031] The limiting component 205 includes a mounting sleeve 2051, which is installed inside the first mounting plate 204. One end of the mounting sleeve 2051 has a through hole 2052. The inner wall of the mounting sleeve 2051 is equipped with a mounting bracket 2053. A conical toothed disc 2054 is rotatably mounted inside the mounting bracket 2053 via ball bearings. The conical toothed disc 2054 has a threaded hole 2055 inside, and a threaded rod 2056 is threadedly connected inside the threaded hole 2055. A sliding rod 2057 is installed on the inner wall of the mounting sleeve 2051, and a sliding sleeve 2058 is sleeved on the outer wall of the sliding rod 2057. The outer wall of the sliding sleeve 2058 is fixedly connected to the outer wall of the threaded rod 2056.

[0032] The top of the mounting sleeve 2051 is rotatably mounted with a rotating shaft body 2059 via a bearing, and a bevel gear 2061 is mounted at the bottom of the rotating shaft body 2059. The bevel gear 2061 meshes with the bevel gear disk 2054. The top of the rotating shaft body 2059 is mounted with a turntable body 2060, and the outer wall of the turntable body 2060 is provided with anti-slip texture. The mounting sleeve 2051 and the limiting hole 2063 cooperate with each other.

[0033] The specific working principle is as follows: When the aeration pipe 102 needs to be installed, firstly, the second mounting base 203 is rotated to open the first mounting base 202, and the aeration pipe 102 is placed inside the first mounting base 202. Then, rotating the second mounting base 203 causes the limiting component 205 to engage with the limiting hole 2063, and rotating the second mounting base 203 causes the limiting component 205 to engage with the through hole 2063. Then, rotating the turntable body 2060 causes the rotating shaft body 2059 to rotate, and the bevel gear 2061 meshes with the bevel gear disc 2054. The bevel gear 2061 rotates to drive the bevel gear disk 2054 to rotate simultaneously. It is threadedly connected to the threaded rod 2056 through the threaded hole 2055 and through the cooperation of the sliding rod 2057 and the sliding sleeve 2058. The rotation of the bevel gear disk 2054 drives the threaded rod 2056 to slide inside the threaded hole 2055 through the sliding rod 2057 and the sliding sleeve 2058. This allows the threaded rod 2056 to slide and cooperate with the bottom end of the second mounting plate 206, thereby facilitating the operator to install and remove the aeration pipe 102 through the first mounting seat 202 and the second mounting seat 203.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
