Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a small sewage treatment device. Background Art

[0002] Water resources are an important resource for our survival. With the continuous development of science and technology at this stage, there is a lot of sewage and dirty water. In order to save water consumption and facilitate users, small sewage treatment devices are often used. However, the existing sewage treatment devices still have certain defects, such as:

[0003] For example, a small sewage treatment device with publication number CN214829340U includes a vertical container, in which a baffle for buffering sewage and making the sewage form a slow flow is installed, and a porous foam plastic partition for preventing air from dissolving into the water body below and making the area below an anoxic environment, the porous foam plastic partition is located above the baffle; an aeration mechanism is provided in the area above the porous foam plastic partition; the vertical container is provided with a water inlet in the area below the baffle, and the vertical container is provided with a water outlet in the area above the porous foam plastic partition.

[0004] The above-mentioned small-scale sewage treatment device can reuse sewage through the vertical distribution of anaerobic zone, anoxic zone and aerobic zone. However, before the sewage enters the device, it needs to be filtered. After a long time of filtration, impurities may accumulate on the filter. After accumulation, the filter needs to be manually moved to clean the filter, which is relatively cumbersome. At the same time, when purifying sewage, it is necessary to cooperate with corresponding chemical agents for purification treatment. As for the addition of chemical agents, it is difficult to grasp the amount of chemical agents that need to be added manually, which easily leads to waste of resources. Utility Model Content

[0006] To achieve the above object, the utility model provides the following technical solution: a small sewage treatment device, comprising a water inlet penetratingly installed on the left side of the upper end of a shell, a driving motor fixedly installed at the center of the upper end of the shell, and a stirring rod fixedly installed at the output end of the driving motor, and a water outlet valve port is arranged at the bottom of the shell;

[0008] A rotating impact plate is rotatably installed inside the shell, and an automatic dosing mechanism is arranged behind the rotating impact plate, and the automatic dosing mechanism drives the rotating impact plate to rotate through the entry of sewage.

[0009] Furthermore, the stirring rod forms a rotating structure with the shell through a driving motor, and a guide plate is fixedly installed at the bottom of the shell, and the inner side of the guide plate is inclined.

[0010] Furthermore, the anti-blocking mechanism is provided with a rotating disc, and the second gear is installed through the bottom of the rotating disc, and a round rod is fixedly installed on the upper end of the rotating disc, and a groove push rod is nested on the surface of the round rod, the left side of the groove push rod is installed through the water inlet, and a return spring is fixedly installed inside the left side of the groove push rod, and a cleaning brush is fixedly installed on the lower end of the return spring, and a filter is nested inside the water inlet.

[0011] Furthermore, the connection mode between the round rod and the groove push rod is a sliding connection, and the shape of the groove push rod is an "I" shape, and the connection mode between the groove push rod and the water inlet is a sliding connection.

[0012] Furthermore, the cleaning brush forms an elastic structure through a return spring and a groove push rod, and the lower end of the cleaning brush fits the surface of the filter screen, and the connection between the filter screen and the water inlet is a sliding connection.

[0013] Furthermore, the automatic dosing mechanism is provided with a rotating impact plate, and a traction rope is wound around the rear of the rotating impact plate, and a baffle is fixedly installed on the lower end of the traction rope, and the baffle is nested and installed inside the dosing pipe, the left side of the dosing pipe passes through the installation shell, and a one-way valve is fixedly installed inside the right side of the dosing pipe.

[0014] Furthermore, the rotating impact plate has three surface transverse plates, and a fixed baffle is provided at the lower right side of the rotating impact plate, and the front end of the fixed baffle is fixedly installed on the inner wall of the shell, and the fixed baffle is provided between the surface transverse plates of the rotating impact plate.

[0015] Furthermore, the rotating impact plate forms a traction structure with the baffle through a traction rope, and the baffle is connected to the drug delivery pipe by a sliding connection, and a medicine box is fixedly installed on the upper left end of the drug delivery pipe, and the right side bolt of the medicine box is installed on the left side of the shell.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. A stirring rod is arranged inside the shell. The arrangement of the stirring rod can ensure that the sewage and the chemical agent are fully mixed after the chemical agent is added, so that the chemical agent can fully exert its effect, improve the speed of sewage treatment, and ensure the effect of sewage treatment;

[0018] Furthermore, the bottom of the stirring rod is provided with four horizontal bars, which can improve the stirring efficiency, make the mixing speed of the chemical agent and the sewage faster, and reduce the time required for mixing, thereby reducing the time consumed for sewage treatment and saving time;

[0019] Furthermore, the groove push rod can be driven to move back and forth while stirring, and the reciprocating movement of the groove push rod can make the cleaning brush move back and forth on the surface of the filter screen, thereby preventing impurities inside the sewage from accumulating on the surface of the filter screen when the sewage is added, thereby avoiding affecting the efficiency of the filter screen in filtering sewage. Manual dredging is not required, which can increase the service life of the filter screen and reduce the number of times the staff disassembles the filter screen for cleaning, thereby providing convenience for the staff and reducing the workload.

[0020] 2. When adding sewage, the impact force of the sewage drives the rotating impact plate to rotate. When the rotating impact plate rotates to the left side of the fixed stop rod, it is blocked. The sewage impacting the rotating impact plate at this time will not drive the rotating impact plate to rotate. It can automatically limit the position, thereby improving the practicality of the device;

[0021] Furthermore, the rotation of the rotating impact plate can pull the baffle up, so that the baffle can connect the drug delivery pipe, so that the chemical agent inside the medicine box can pass through the drug delivery pipe into the shell, and be mixed with the sewage for purification. When the sewage stops being added, the rotating impact plate is reversed and reset by the gravity of the baffle. At this time, the baffle is re-embedded in the drug delivery pipe, and the injection of chemicals can be automatically stopped, thus achieving the effect of automatic drug delivery. There is no need for manual drug delivery, and at the same time, it avoids the problem of manual drug delivery metering, saves resource consumption, and avoids the waste of resources caused by excessive addition of chemicals.
