Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an aeration device for sewage treatment. Background Art

[0002] Aeration is a process of forcibly adding oxygen to sewage. By using certain methods and equipment to force air into the sewage, the sewage in the pool is brought into contact with the air and oxygenated. The liquid is stirred to accelerate the transfer of oxygen from the air to the liquid, preventing suspended objects in the pool from sinking, and strengthening the contact between organic matter in the pool and microorganisms and dissolved oxygen, thereby oxidizing and decomposing organic matter in the sewage.

[0003] At present, the aeration nozzles in the aeration equipment are usually fixedly installed at the bottom of the pool, resulting in a fixed working range of the aeration nozzles. In addition, when aerating sewage, the current aeration equipment usually simply sprays gas into the sewage through the aeration nozzles, which ultimately results in low efficiency of the entire aeration work. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of the present utility model is to provide an aeration device for sewage treatment, in which the working range of the aeration nozzle is wider during aeration work, and the water body is stirred under the rotation of the circulating screw and the aeration nozzle, which can accelerate the transfer of oxygen in the air to the liquid, thereby improving the efficiency of the aeration work.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] An aeration device for sewage treatment comprises a box body and an installation box arranged in sequence from top to bottom, the upper end of the box body is fixedly connected to a motor, the box body is provided with a plurality of connecting valve heads communicated with the interior, a rotating shaft is rotatably provided on the upper side wall of the box body, the rotating shaft is transmission-connected to the motor, a through-hole is provided on the upper side of the installation box, a rotating plate is sealingly and rotatably connected in the through-hole, a first bevel gear is fixedly provided on the lower side of the rotating plate, the lower side of the rotating shaft passes through the rotating plate and extends into the installation box to be fixedly connected to an air storage box, aeration components are provided around the air storage box, ventilation components are provided between the four aeration components and the air storage box, a ventilation member is provided between the air storage box and the box body, and a first limiter is provided between the first bevel gear and the lower side of the box body;

[0007] The aeration component includes a ventilation box, a circulation screw, a ring sleeve, a retractable hose, an aeration nozzle, a hollow hard tube, a second bevel gear and a second limiter. The ventilation box is fixedly arranged on the side of the installation box, the circulation screw is rotatably arranged on the outside of the ventilation box, the second bevel gear is rotatably arranged on the side wall of the installation box, and the second bevel gear is engaged with the first bevel gear. One end of the hollow hard tube passes through the middle of the second bevel gear and extends into the air storage box to be connected with the interior of the air storage box, and the hollow hard tube is sealed and rotatably connected to the air storage box, the installation box and the ventilation box. The hollow The hard tube is transmission connected to the second bevel gear, and the other end of the hollow hard tube passes through the installation box and the ventilation box in sequence and is transmission connected to the circulation screw, and the side of the hollow hard tube is provided with an air hole located inside the ventilation box, the annular sleeve is rotatably provided on the circulation screw, the aeration nozzle is installed on the upper end of the annular sleeve, the second limiter is provided between the annular sleeve and the installation box, one end of the retractable hose is communicated with the interior of the ventilation box, and an air duct connected to the aeration nozzle is provided inside the annular sleeve, and the other end of the retractable hose is communicated with the air duct.

[0008] Compared with the prior art, the beneficial effect of the present invention is that it is connected to the external inflation equipment through the connecting valve head on the box body, and the redundant connecting valve heads can be arranged and connected with multiple devices to fill the entire aeration tank. The number of devices used can be flexibly selected according to the size of the aeration tank, and the aeration equipment does not need to be customized according to the size of the aeration tank, which greatly reduces the workload of the early installation of the aeration tank. The box body is in a stationary state and cannot rotate or move through the restrictive effect of the external pipeline. Then, the motor is started, and the motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the air storage box to rotate. The rotation of the air storage box will simultaneously drive the four hollow hard tubes to rotate. The rotation of the hollow hard tube will drive the second bevel gear to rotate, and at the same time drive the installation box to rotate. At this time, the first bevel gear and the rotating plate are limited by the first limit piece, so the first bevel gear cannot rotate. Since the four second bevel gears are all engaged with the first bevel gear, the four second bevel gears will rotate when they are driven to rotate. At this time, since the four hollow hard tubes are respectively connected to the four second bevel gears for transmission, at this time, the hollow hard tube drives the second bevel gear to rotate. The lower four circulating screws will revolve around the rotating shaft and rotate at the same time. Since the ring sleeve on the circulating screw is restricted by the second limiter and cannot rotate, the ring sleeve will reciprocate along the direction of the circulating screw, gradually moving away from and approaching the rotating shaft, thereby driving the aeration nozzle to reciprocate, and the aeration nozzle will rotate around the rotating shaft while reciprocating. When the ring sleeve reciprocates, the retractable hose will continue to stretch and compress. When the motor is started, the gas is passed through the external inflation device. The connecting valve head is filled into the box body, and then the gas is rushed into the air storage box through the vent, and then enters the hollow hard tube through the air storage box, and then enters the vent box through the air hole of the hollow hard tube, and then enters the retractable hose into the air channel of the ring sleeve, and finally enters the aeration nozzle through the air channel and is ejected through the aeration nozzle; in this way, the working range of the aeration nozzle is wider during aeration work, and the water body is stirred under the rotation of the circulating screw rod and the aeration nozzle, which can accelerate the transfer of oxygen in the air to the liquid, thereby improving the efficiency of the aeration work.

[0009] As a preferred embodiment of the present invention, the ventilator comprises an air passage provided inside the rotating shaft, and the two openings of the air passage are respectively connected to the box body and the interior of the gas storage box;

[0010] Beneficial effect: Gas is injected into the box body through external equipment, and then the gas enters the ventilation channel through the opening of the rotating shaft on the side surface of the box body, and finally enters the gas storage box through the opening of the rotating shaft in the gas storage box, and finally enters the aeration nozzle through the hollow hard tube, the ventilation box, the retractable hose and the air channel in the ring sleeve and is ejected, thus ensuring that the aeration nozzle can also eject sufficient gas when it is in motion.

[0011] As a preferred embodiment of the present invention, the first limiting member includes two limiting rods, which are symmetrically arranged between the upper side of the first bevel gear and the lower side of the box body, and the limiting rods are sealed and pass through the rotating plate;

[0012] Beneficial effect: The connecting valve head of the box body cannot rotate or move after being connected to the external inflation equipment, so that the first bevel gear cannot rotate after the motor is started, thereby ensuring that the second bevel gear can rotate while revolving, thereby ensuring that the aeration nozzle can reciprocate close to and away from the rotating shaft while rotating.

[0013] As a preferred embodiment of the present invention, the second limiting member includes a slide rail, a slider and a blocking plate, the blocking plate is fixedly arranged on the side of the circulating screw away from the installation box, the slide rail is fixedly arranged between the installation box and the side of the blocking plate close to the installation box, the slider is slidably arranged in the slide rail, and the upper end of the slider is connected to the ring sleeve;

[0014] Beneficial effect: The slider is fixedly connected to the ring sleeve, and the slider slides in the slide rail and cannot rotate, so the ring sleeve cannot rotate. This ensures that when the circulating screw rotates, the ring sleeve can follow its thread to make reciprocating motion gradually away from and gradually approaching the rotating shaft.
