[0002] At present, in sewage treatment, the water quality of sewage is monitored, the water quality data obtained by monitoring is analyzed through intelligent analysis, and then the release device is controlled accordingly to release microbial particles to biologically treat sewage through microorganisms. The microorganisms released by existing microbial release devices are relatively concentrated, resulting in uneven distribution of microorganisms in large water surface sewage, resulting in less than ideal sewage treatment effects. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic microbial delivery device for sewage treatment, which can control the delivery distance and direction of the microbial particles, and scatter the microbial particles more evenly, which is conducive to achieving the best effect of microbial treatment, and is conducive to reducing manpower input, and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic microbial delivery device for sewage treatment, comprising a delivery device installation mechanism, the delivery device installation mechanism comprises a C-shaped support rod and a fixed frame, a fixed frame is installed on the right side of the top of the C-shaped support rod, and also includes:

[0005] A microorganism release mechanism comprises a microorganism particle bin, a partition, a rotating shaft, a release roller, a circular groove and a release motor. The microorganism particle bin is fixedly sleeved in a fixed frame. The bottom cross section of the microorganism particle bin is a semicircular mechanism. The microorganism particle bin is divided into two identical microorganism particle cavities by a partition. A feeding port corresponding to the two microorganism particle cavities is provided at the bottom of the microorganism particle bin. The bottom of each microorganism particle cavity is rotatably connected with a rotating shaft. The ends of the two rotating shafts extend to the outside of the microorganism particle bin and are fixedly connected with the output shaft of the release motor. Each release motor is installed on the microorganism particle bin through a motor seat. The rotating shaft is fixedly sleeved with the central circular hole of the release roller. The release roller cooperates with the bottom of the microorganism particle cavity, and a plurality of circular grooves are provided in an annular array on the outer circumference of the release roller.

[0006] A microorganism collection component is installed at the bottom of the microorganism particle bin;

[0007] The microbial particle throwing and delivering mechanism is installed at the bottom of the microbial collection component;

[0008] The throwing direction control mechanism is installed on the right side of the bottom end of the C-shaped support rod, and the throwing direction control mechanism is connected to the bottom of the microbial particle throwing and delivering mechanism.

[0009] The fixed frame is used to install the microbial particle bin. The two microbial particle cavities in the microbial particle bin are used to hold different microbial particles. Two different microorganisms can be added to the sewage as needed. The release motor drives the release roller to rotate at the bottom of the microbial particle cavity through the rotating shaft. The microbial particles in the microbial particle cavity enter the circular groove on the upper side of the release roller. Then, as the release roller rotates, the circular groove containing the microbial particles faces downward, and the microbial particles in the circular groove fall into the microbial collection component through the discharge port. When the release motor is not working, the microbial particles in the microbial particle cavity cannot fall, so that the different microbial particles in the two microbial particle cavities are controlled by the two release motors to fall into the microbial collection component. Both release motors use servo motors. By controlling the two release motors to rotate at different speeds, the discharge speed of the two microbial particles can be changed. The microbial particles in the microbial collection component fall into the microbial particle throwing and delivery mechanism, and the microbial particles are thrown out by the microbial particle throwing and delivery mechanism. The throwing direction control mechanism can change the direction of the microbial particle throwing and delivery mechanism to throw the microbial particles in different directions.

[0010] Furthermore, the microorganism collection component includes a collection funnel and a collection pipe, the bottom of the microorganism particle bin is fixedly connected to the collection funnel, and the bottom of the collection funnel is fixedly connected to the top of the collection pipe. The two kinds of microorganism particles falling from the two feeding ports are collected in the collection funnel, and then fall uniformly through the collection pipe, so that the two kinds of microorganism particles can be thrown out by the microorganism particle throwing and delivery mechanism.

[0011] Furthermore, the microbial particle sprinkling and delivery mechanism includes a circular ring, a delivery circular shell, a sprinkling port, a sprinkling motor, a sprinkling shaft, a mounting roller, an arc-shaped sprinkling plate and an inclined plate. A sprinkling port is opened on the right side of the delivery circular shell, and a circular ring is fixedly connected to a position of the delivery circular shell corresponding to the top of the sprinkling port. The circular ring is rotatably connected to the bottom end of the collecting pipe, and an inclined plate is fixedly connected to a position of the delivery circular shell corresponding to the bottom end of the sprinkling port. The inclined plate is tilted so that it is higher on the left and lower on the right. A sprinkling shaft is rotatably connected to the middle part of the delivery circular shell, and a mounting roller is fixedly sleeved on the middle part of the sprinkling shaft. A plurality of arc-shaped sprinkling plates are arranged in a circular array on the outer peripheral side of the mounting roller. One end of the sprinkling shaft is fixedly connected to the output shaft of the sprinkling motor, and the sprinkling motor is fixed on the outer side of the delivery circular shell. The spreading motor drives the spreading shaft and the mounting roller to rotate counterclockwise, thereby driving the arc-shaped spreading plate to rotate. The microbial particles falling from the bottom of the collecting pipe fall into the distribution round shell. The rotating arc-shaped spreading plate will generate centrifugal force on the microbial particles, causing the microbial particles to be scattered from the spreading port. The inclined plate limits the microbial particles coming out of the bottom of the spreading port, and the microbial particles scattered from the bottom of the spreading port are thrown out along the upper side of the inclined plate.

[0012] Furthermore, the throwing direction control mechanism includes a support, a vertical axis, a control motor and a motor frame. The support is fixedly connected to the right side of the bottom end of the C-shaped support rod, and the support is rotatably connected to the vertical axis. The vertical axis is arranged concentrically with the circular ring. The top of the vertical axis is fixedly connected to the bottom of the inclined plate, and the bottom of the vertical axis is fixedly connected to the output shaft of the control motor. The control motor is fixed to the C-shaped support rod through the motor frame. The motor frame is used to install the control motor. The control motor drives the vertical axis to rotate relative to the support, thereby driving the delivery shell to rotate, so that the throwing port can be directed to different directions, thereby changing the throwing direction of the microbial particles. The control motor adopts a servo motor, which can rotate forward and backward.

[0013] Furthermore, it also includes a throwing distance control mechanism, which is installed on the upper side of the inclined plate and can change the throwing distance of the microbial particles.

[0014] Furthermore, the scattering distance control mechanism includes a groove, a control shaft, a scattering guide plate and a guide plate support assembly. A groove is provided on the upper side of the inclined plate. One end of the groove close to the delivery round shell is connected to the left end of the scattering guide plate by rotation through the control shaft. The guide plate support assembly is installed on the inclined plate. The scattering guide plate can change its angle in the groove through the control shaft. The microbial particles scattered from the bottom of the scattering port fly out along the upper side of the scattering guide plate. When the angle between the scattering guide plate and the inclined plate increases, the elevation angle of the microbial particles becomes larger, which is conducive to the microbial particles flying farther, thereby changing the scattering distance of the microbial particles. After the angle of the scattering guide plate is adjusted to a suitable position, the guide plate support assembly supports the bottom of the scattering guide plate to fix the position of the scattering guide plate.

[0015] Furthermore, the deflector support assembly includes a control stud and a knob, a vertical control stud is threadedly connected to the middle of one end of the inclined plate away from the delivery round shell, a knob is fixedly connected to the bottom end of the control stud, and the top end of the control stud abuts against the lower side of the delivery deflector. The knob is used to rotate the control stud, and the threaded action of the control stud and the inclined plate can move up and down relative to the inclined plate, so that the control stud can change its height to support the bottom of the delivery deflector at different angles.

[0016] Compared with the prior art, the beneficial effects of the automatic microbial delivery device for sewage treatment are:

[0017] 1. The throwing motor drives the throwing shaft and the installation roller to rotate counterclockwise, thereby driving the arc-shaped throwing plate to rotate. The microbial particles falling from the bottom of the collecting pipe fall into the throwing round shell. The rotating arc-shaped throwing plate will generate centrifugal force on the microbial particles, so that the microbial particles are thrown out from the throwing port. The throwing guide plate can change the angle in the groove through the control shaft. When the angle between the throwing guide plate and the inclined plate becomes larger, the elevation angle of the microbial particles thrown out becomes larger, which is conducive to the microbial particles flying farther, thereby changing the throwing distance of the microbial particles;

[0018] 2. The control motor drives the vertical axis to rotate relative to the support, thereby driving the delivery round shell to rotate, so that the delivery port can be directed to different directions, thereby changing the delivery direction of the microbial particles;

[0019] 3. The distance and direction of the microbial particles can be controlled, and the microbial particles can be scattered more evenly, which is conducive to achieving the best effect of microbial control. It does not require manual placement, which is conducive to reducing manpower input. BRIEF DESCRIPTION OF THE DRAWINGS
