Description

Technical Field

[0001] The utility model relates to the technical field of aeration equipment, in particular to an aerator with adjustable angle. Background Art

[0002] Aeration refers to the process of forcibly transferring and dispersing gas (usually oxygen in the air) into a liquid, with the aim of obtaining sufficient dissolved oxygen. In addition, aeration also serves to prevent the suspension in the pool from sinking and to enhance the contact between the organic matter in the pool, microorganisms, and dissolved oxygen. Thus, it ensures that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. The aeration process often appears in the biochemical treatment processes of industrial sewage such as textile, printing and dyeing, paper making, and chemical industries, as well as urban domestic sewage, and various aquaculture fields and salt production fields. Since dissolved oxygen is required in biochemical sewage treatment, corresponding aerators are needed to achieve aeration, and there are a wide variety of aerators at home and abroad.

Specific embodiments

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] See Figure 1 、 Figure 2 and Figure 3 The present utility model provides an angle-adjustable aerator. The angle-adjustable aerator includes an intake main pipe 1, and a plurality of intake branch pipes 2 are provided at the tail thereof. Air is supplied into the interior of the intake main pipe 1 through an air supply mechanism and then aeration is carried out through the intake branch pipes 2; a connecting tee 3 connecting the two intake branch pipes 2, and an aeration head 5 is rotatably connected to the free end of the connecting tee 3. The aeration head 5 is connected to the intake branch pipe 2 through the connecting tee 3 to ensure the air supply effect of the intake branch pipe 2 on the aeration head 5 and ensure the aeration process of the aeration head 5. A plugging member is provided at the free end of the connecting tee 3 to prevent blockage of the connecting tee 3 through the plugging member. When the connecting tee 3 is not connected to the aeration head 5, the connecting tee 3 is in a plugged state to prevent gas from leaking from the connecting tee 3. The plugging member plugs the free end of the connecting tee 3 before installing the aeration head 5. When the aeration head 5 is connected to the connecting tee 3, the aeration head 5 is in communication with the interior of the intake branch pipe 2, so as to achieve the connection effect between the aeration head 5 and the connecting tee 3.

[0021] See Figure 3 and Figure 4, preferably, the plugging member of the present utility model is a ball 8. The inner part of the free end of the connecting tee 3 is provided with a sliding hole, and a spherical groove 32 is provided at the bottom of the sliding hole. The ball 8 cooperates with the spherical groove 32 to seal the sliding hole, ensuring that the sealing effect of the free end of the connecting tee 3 can be controlled by the position of the ball 8. A limiting flange is provided at the bottom of the free end of the connecting tee 3, and a thrust spring 7 is provided between the limiting flange and the ball 8. The ball 8 is pressed into the interior of the spherical groove 32 under the action of the thrust spring 7, and the thrust spring 7 provides the fitting sealing force of the ball 8 against the spherical groove 32, ensuring that the on-off state of the free end of the connecting tee 3 is controlled by the ball 8.

[0022] See Figure 5 , in addition, an intermediate sleeve 6 is inserted into the interior of the sliding hole of the present utility model. One end of the intermediate sleeve 6 located inside the sliding hole is provided with an abutting necking 64 for pushing the ball 8 to slide. By abutting the abutting necking 64 against the ball 8, the ball 8 is pushed to slide inside the sliding hole, so that after the intermediate sleeve 6 is installed, the free end of the connecting tee 3 can be in a communicating state. An air vent hole 63 is provided between the abutting necking 64 and the intermediate sleeve 6. After the intermediate sleeve 6 is inserted in place, the air vent hole 63 communicates with the interior of the intake branch pipe 2, so that air is supplied to the interior of the intermediate sleeve 6 through the intake branch pipe 2.

[0023] Furthermore, in combination with Figures 1 to 5 , one end of the intermediate sleeve 6 of the present utility model located outside the sliding hole is provided with a threaded portion 61. A screw sleeve 4 is provided outside the intermediate sleeve 6. One end of the screw sleeve 4 is screwed onto the threaded portion. The aeration head 5 is screwed onto the other end of the screw sleeve 4. By screwing the screw sleeve 4 onto the threaded portion, the connection relationship between the screw sleeve 4 and the intermediate sleeve 6 is ensured, and further the connection of the aeration head 5 is realized. Vertical grooves 33 and transverse grooves 31 connected to the ends of the vertical grooves 33 are provided on the inner wall of the sliding hole. Protrusions 62 corresponding to the vertical grooves 33 and the transverse grooves 31 are provided on the outer wall of the intermediate sleeve 6. When installing the intermediate sleeve 6, first insert the intermediate sleeve 6 into the vertical groove 33, and then after inserting in place, rotate by a certain angle to make the protrusion 62 snap into the interior of the transverse groove 31 to complete the installation of the intermediate sleeve 6. When installing the screw sleeve 4, the tightening direction of the screw sleeve 4 is the same as the rotation direction of the intermediate sleeve 6 when it is inserted into the transverse groove 31. Therefore, after the screw sleeve 4 is tightened, the protrusion 62 and the transverse groove 31 can be pressed tighter. When the inclination angle of the aeration head 5 needs to be adjusted, rotating the aeration head 5 will not drive the screw sleeve 4 to rotate, realizing the adjustment of the angle of the screw sleeve 4.

[0024] In summary, the present utility model provides an aerator with adjustable angle, including: a main air inlet pipe, at the tail of which there are several air inlet branch pipes, and air is supplied to the inside of the main air inlet pipe through an air supply mechanism and then through the air inlet branch pipes for aeration effect; a connecting tee connecting the two air inlet branch pipes, the free end of the connecting tee is rotatably connected with an aeration head, and the aeration head is connected with the air inlet branch pipe through the connecting tee to ensure the air supply effect of the air inlet branch pipe on the aeration head and ensure the aeration process of the aeration head. A blocking member is provided at the free end of the connecting tee to prevent blockage of the connecting tee. When the connecting tee is not connected with the aeration head, the connecting tee can be in a blocked state to prevent gas leakage from the connecting tee. The blocking member blocks the free end of the connecting tee before installing the aeration head. When the aeration head is connected to the connecting tee, the aeration head is communicated with the inside of the air inlet branch pipe, so as to realize the connection effect between the aeration head and the connecting tee. In summary, the technical effect produced by the present utility model is to provide a disc-type aeration device, and by setting a coil structure and a rotatable aeration head on the coil, it is ensured that the angle of the aeration head can be adjusted, and thus the aeration angle can be adjusted.
