Description

Technical Field

[0001] The utility model relates to the technical field of aeration heads, in particular to a sewage treatment swing-type aeration head. Background Art

[0002] Aeration is a means of strongly contacting air with water, aiming to dissolve oxygen in the air into the water, or expel unnecessary gases and volatile substances in the water into the air; in other words, it is a means of promoting mass transfer between gas and liquid. It also has some other important functions, such as mixing and stirring. Oxygen in the air is transferred to the water through aeration, and the oxygen undergoes mass transfer from the gas phase to the liquid phase.

[0003] The Chinese utility model patent with the application number CN202320650474.5 in the prior art relates to an aeration head for water treatment, including a cover body, an aeration membrane, a connection groove, a sealing ring, a pressing sleeve, a connection head, etc., which solves the defect in the prior art that the service life of the aeration head is easily reduced due to the long-term immersion of the aeration head in the liquid.

[0004] However, in actual use, the air outlet position and direction of the aeration head of the above device are fixed, so the scope of its action is fixed, and the sewage aeration treatment effect on the side and lower side of the aeration head is poor. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a sewage treatment swing-type aeration head that completes the aeration operation of sewage through an aeration device, increases the action range of the aeration head, drives the aeration head on the aeration device to swing through a swing device, increases the effective action range of the aeration head, limits the floating height of the swing device through a limit device to prevent the swing device from floating too high and damaging the aeration device, and controls the up and down movement of the swing device through a drive device, improving the practicability of the device.

[0006] A sewage treatment swing-type aeration head of the utility model; includes an aeration device, a swing device, a limit device and a drive device. The swing device is connected to the aeration device, the limit device is installed on the swing device, and the drive device is connected to the aeration device; the aeration operation of sewage is completed through the aeration device, and the action range of the aeration head is increased. The aeration head on the aeration device is driven to swing through the swing device, increasing the effective action range of the aeration head. The floating height of the swing device is limited through the limit device to prevent the swing device from floating too high and damaging the aeration device. The up and down movement of the swing device is controlled through the drive device, improving the practicability of the device.

[0007] Preferably, the aeration device includes an air delivery pipe, fixed clamps, connectors, hoses, and an aeration head body. Multiple groups of fixed clamps are sleeved on the air delivery pipe. Multiple groups of connectors are evenly arranged on the upper end surface of the air delivery pipe. The output end of the connector is connected to the input end of the aeration head body through a hose. The height and position of the air delivery pipe are fixed by the fixed clamps. Air is delivered to multiple groups of aeration head bodies through the air delivery pipe. Due to the characteristics of the hose itself, the aeration head body can swing freely during the aeration process, thereby increasing the effective action range of the aeration head body and improving the practicability of the device.

[0008] Preferably, the swinging device includes a lifting plate, a first limiting optical rod, a lifting ring, and a cross reinforcing rib. The lifting plate is located above the air delivery pipe. Multiple groups of lifting rings are arranged on the lifting plate corresponding to the positions of multiple groups of hoses. A first limiting optical rod is vertically connected to the upper end surface of the fixed clamp. Circular limiting holes are arranged on the lifting plate corresponding to the positions of the first limiting optical rods. The first limiting optical rod passes through the circular limiting holes on the lifting plate. The hoses pass through the lifting rings on the lifting plate. A group of cross reinforcing ribs is arranged between every two groups of lifting rings on the lifting plate. The overall strength of the lifting plate is increased by multiple groups of cross reinforcing ribs on the lifting plate, preventing the lifting plate from deforming under its own stress. The lifting rings move up and down with the lifting plate, driving the aeration head body to rise during the upward movement, so that the action position and direction of the aeration head body are fixed. When the lifting rings follow the lifting plate to fall, the aeration head body is released, enabling the aeration head body to swing by itself to increase the effective action range of the aeration head body. The up and down movement process of the lifting plate is limited by the first limiting optical rod, improving the practicability of the device.

[0009] Preferably, a wear-resistant metal wire is wound around the hose. By winding the wear-resistant metal wire around the hose, the situation of damage to the hose's own structure caused by friction between the lifting ring and the hose during the lifting and lowering process of the lifting plate is reduced, improving the practicability of the device.

[0010] Preferably, the limiting device includes a limiting sleeve, a rubber protection pad, and a fastening bolt. The limiting sleeve is sleeved on the upper part of the first limiting optical rod. A rubber protection pad is arranged on the lower end surface of the limiting sleeve. A fastening bolt is installed on the side of the limiting sleeve. The rising height of the lifting plate is limited by adjusting the limiting sleeve, preventing the lifting plate from rising too high and damaging the aeration head body. The effective action position of the limiting sleeve is fixed by rotating the fastening bolt. The rubber protection pad reduces the scratches caused by the direct collision between the lifting plate and the limiting sleeve during the rising process of the lifting plate, improving the practicability of the device.

[0011] Preferably, the driving device includes an airbag, a first waterproof solenoid valve, and a second waterproof solenoid valve. A set of airbags are respectively connected to the left and rear parts of the upper end surface of the lifting plate. The input end of the airbag is connected to the air supply pipe through a hose. The second waterproof solenoid valve is installed on the input end of the airbag. The output end of the airbag is located at the upper part of the airbag, and the first waterproof solenoid valve is installed on the output end of the airbag. By inflating the airbag through the air supply pipe, the buoyancy of the airbag is increased, driving the lifting plate to float upward, and then fixing the action position and direction of multiple aeration head bodies. Opening the first waterproof solenoid valve and closing the second waterproof solenoid valve releases the air in the airbag, causing the airbag and the lifting plate to fall and release multiple aeration head bodies, enabling the multiple aeration head bodies to swing by themselves, improving the practicability of the device.

[0012] Preferably, it further includes a second limit optical rod and a limit collar. The limit collar is sleeved on the middle part of the side surface of the airbag. A set of second limit optical rods are respectively fixed on the ground on the front and rear sides of the air supply pipe. Both groups of second limit optical rods pass through the limit collar. By passing the two groups of second limit optical rods through the limit collar, the position of the airbag is fixed, preventing the airbag from swinging with the water flow when not inflated inside, improving the practicability of the device.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The aeration operation of sewage is completed through the aeration device, and the action range of the aeration head is increased. The aeration head on the aeration device is driven to swing by the swinging device, increasing the effective action range of the aeration head. The floating height of the swinging device is limited by the limiting device to prevent the swinging device from floating too high and damaging the aeration device. The driving device controls the up and down movement of the swinging device, improving the practicability of the device. Description of the Drawings
