Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a wastewater biological treatment reactor for environmental protection. Background Technology

[0002] A wastewater biological treatment reactor is a device used for wastewater treatment. It uses biological processes to convert organic pollutants in wastewater into harmless substances. Common types of bioreactors include anaerobic reactors, aerobic reactors, and membrane bioreactors. Aerobic reactors usually require the injection of a large amount of oxygen into the water to achieve a suitable oxygen concentration for the proliferation of aerobic decomposing bacteria. In actual use, existing aerobic bioreactors usually require a stirring device to ensure that the oxygen injected from the air and the water are fully mixed. Since stirring and oxygen injection are mostly two independently operating devices, the operating cost of the device is relatively high.

[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a wastewater biological treatment reactor for environmental protection, in order to achieve a more practical value. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wastewater biological treatment reactor for environmental protection, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a wastewater biological treatment reactor for environmental protection, comprising an aeration tank, a main air pipe 1 disposed above the aeration tank, an air pump connected to one end of the main air pipe 1, multiple sets of jet stirring components uniformly and rotatably installed at the bottom of the main air pipe 1, a support block 2 fixedly installed at the lower inner side of the aeration tank, the jet stirring components including a branch air pipe 2, the branch air pipe 2 rotatably extending into the main air pipe 1, the bottom end of the branch air pipe 2 rotatably connected to the support block 2, multiple hollow stirring blades uniformly installed on the side wall of the branch air pipe 2, interconnected air channels provided between the branch air pipe 2 and the hollow stirring blades, and a number of jet nozzles uniformly arranged on one side of the hollow stirring blades.

[0006] Furthermore, the hollow stirring blades on the two adjacent sets of jet stirring components are symmetrically arranged. By making the rotation directions of the two sets of jet stirring components opposite, the stirring and mixing effect on the wastewater in the aeration tank is improved, thereby fully increasing the oxygen content in the wastewater.

[0007] Furthermore, the hollow stirring blade and the second branch pipe are detachably connected by connecting bolts. The connection between the hollow stirring blade and the second branch pipe can be disassembled by connecting bolts so that workers can clean or replace the damaged or blocked hollow stirring blade.

[0008] Furthermore, the jet nozzle is configured to tilt downwards, so that the jet nozzle faces the bottom of the aeration tank. When the jet nozzle emits air, the gas can continuously impact the bottom of the aeration tank, causing the sediment at the bottom of the aeration tank to be stirred up and thus fully purified by the aerobic bacteria in the water.

[0009] Furthermore, a sealing gasket is provided between the main air tube and the bronchus tube, and the sealing gasket is fixedly connected to the inner wall of the main air tube. The sealing gasket improves the sealing performance of the connection between the main air tube and the bronchus tube, preventing gas from leaking from the connection gap between the main air tube and the bronchus tube.

[0010] Furthermore, a support block 1 is fixedly installed on the upper inner side of the aeration tank, and the two branch pipes rotatably pass through the support block 1. The rotational stability of the two branch pipes is improved by the support block 1, thereby ensuring the long-term stable operation of the device.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model is equipped with a support block, a branch pipe, a hollow stirring blade, a jet nozzle, an air pump, and a main air pipe. In use, the hollow stirring blade is driven by gas to rotate, which can stir the wastewater inside the aeration tank. This allows the oxygen in the injected gas to be fully mixed with the wastewater, thereby saving the operating cost of the device and greatly improving its practicality.

[0013] 2. By setting the nozzle of the device to be tilted downwards, the gas emitted from the nozzle can continuously impact the bottom of the aeration tank, thereby moving the sediment at the bottom of the aeration tank and allowing it to be fully purified by aerobic bacteria in the water, which greatly improves the practicality of the device.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example 1: Please refer to Figure 1-4 This utility model provides an environmentally friendly wastewater biological treatment reactor, comprising an aeration tank 100, a main air pipe 102 disposed above the aeration tank 100, an air pump 101 connected to one end of the main air pipe 102, and multiple sets of jet stirring components 105 evenly rotatably mounted at the bottom of the main air pipe 102. A support block 122 is fixedly installed on the lower inner side of the aeration tank 100. The jet stirring components 105 include branch air pipes 111, which rotatably extend into the main air pipe 102. The bottom end of the branch air pipes 111 is rotatably connected to the support block 122. Multiple hollow stirring blades 112 are evenly mounted on the side wall of the branch air pipes 111. An interconnected air passage is provided between the branch air pipes 111 and the hollow stirring blades 112. A number of jet nozzles 113 are evenly arranged on one side of the hollow stirring blades 112.

[0020] Working principle: During use, wastewater is injected into the aeration tank 100, and then air is drawn from the outside through the air pump 101. The air is introduced into the branch pipe 111 through the main air pipe 102. The gas in the branch pipe 111 is transported to the hollow stirring blade 112 through the connecting air passage and discharged through the jet nozzle 113 on the side of the hollow stirring blade 112. The discharged gas will come into contact with the wastewater in the aeration tank 100, thereby increasing the oxygen content in the water. Secondly, when the gas is discharged from the jet nozzle 113, the discharged gas will push the hollow stirring blade 112, thereby driving the branch pipe 111 to rotate. At this time, the hollow stirring blade 112 will stir the wastewater in the aeration tank 100, so that the wastewater can come into full contact with the gas. In addition, the downward tilted jet nozzle 113 will blow away the particles deposited at the bottom of the inner side of the aeration tank 100.

[0021] Example 2:

[0022] The difference between Embodiment 2 and Embodiment 1 is that: the hollow stirring blades 112 on the two adjacent sets of jet stirring components 105 are symmetrically arranged; the hollow stirring blades 112 and the branch pipe 2 111 are detachably connected by connecting bolts 121; the jet port 113 is set to be inclined downwards; a sealing gasket 120 is interference-fitted between the main air pipe 102 and the branch pipe 2 111; the sealing gasket 120 is fixedly connected to the inner wall of the main air pipe 102; a support block 110 is fixedly installed on the upper inner side of the aeration tank 100; and the branch pipes 2 111 all rotatably penetrate through it. When in use, the hollow stirring blades 112 on the two sets of jet stirring components 105 are symmetrical, and the jet nozzles 113 on the hollow stirring blades 112 are also symmetrical. Therefore, the gas will drive the two sets of jet stirring components 105 to rotate in opposite directions to improve the stirring effect on the wastewater inside the aeration tank 100. The connection between the hollow stirring blades 112 and the support block 110 is disassembled by connecting bolts 121, and the sealing gasket 120 is used to improve the sealing of the connection between the branch pipe 111 and the main pipe 102.

[0023] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
