Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a wastewater diversion and purification device. Background Technology

[0002] In the field of wastewater treatment, with the rapid development of industrialization and urbanization, wastewater discharge is increasing daily, and the demand for wastewater purification and treatment is becoming increasingly urgent. Efficient wastewater treatment technologies can effectively reduce the harm of pollutants to the environment, protect water resources, and are of great significance for maintaining ecological balance and promoting sustainable development. A good wastewater treatment system can reduce the content of harmful substances in wastewater, ensuring it meets discharge standards before being released, thus avoiding pollution of soil and water bodies. It also helps improve the recycling rate of water resources and alleviate the pressure of water scarcity.

[0003] In traditional wastewater treatment methods, a single sewage pipe is typically used to transport wastewater into the wastewater treatment tank. This method is relatively simple to operate, the pipe laying is relatively easy, and the cost is relatively low. However, once the wastewater enters the tank through a single pipe, the concentration at the inlet remains consistently high. The wastewater needs a considerable amount of time to diffuse naturally and reach all areas of the tank, thus failing to reach the microorganisms and achieve purification. This makes the entire wastewater treatment process inefficient and unable to meet the ever-increasing demand for wastewater treatment. Utility Model Content

[0004] In order to enable the wastewater entering the wastewater tank to be quickly distributed to different areas of the wastewater tank and improve the purification efficiency, this application provides a wastewater diversion and purification device.

[0005] The wastewater diversion and purification device provided in this application adopts the following technical solution:

[0006] A wastewater diversion and purification device includes a wastewater tank, a mounting frame, a main inlet pipe, and branch inlet pipes. The mounting frame is connected to the upper end of the wastewater tank, and the main inlet pipe is connected to the mounting frame. One end of the main inlet pipe is used to connect to an external wastewater pump. The upper end of each branch inlet pipe is connected to the main inlet pipe, and the lower end of each branch inlet pipe extends into the wastewater tank. Several branch inlet pipes are provided and are evenly distributed in the wastewater tank.

[0007] By adopting the above technical solution, multiple inlet branch pipes are evenly distributed in the sewage tank, which first transports the sewage to various parts of the sewage tank, reducing the time required for the sewage to spread to various parts of the sewage tank, so that the sewage can come into full contact with microorganisms as soon as possible to react and improve the purification efficiency of the equipment.

[0008] Preferably, it further includes a lateral movement component, wherein the mounting frame is slidably connected to the sewage tank, the sliding direction of the mounting frame is horizontal, the lateral movement component is connected to the sewage tank, and the lateral movement component is used to drive the mounting frame to slide.

[0009] By adopting the above technical solution, a transverse component is set up to drive the mounting frame to slide, thereby moving the main inlet pipe and the branch inlet pipe. This changes the position of the sewage entering the sewage tank from the pipe, and the sewage in the sewage tank is disturbed through the branch inlet pipe, which accelerates the diffusion of sewage and improves the purification efficiency of the equipment.

[0010] Preferably, the system also includes rollers. The upper end of the sewage tank is provided with guide grooves. There are two guide grooves, which are distributed at intervals along the sliding direction perpendicular to the mounting frame. The rollers are connected to the mounting frame and are embedded in the guide grooves. There are a plurality of rollers, which are divided into two groups. The two groups of rollers correspond to two guide grooves, and the rollers in the same group are distributed at intervals along the sliding direction of the mounting frame.

[0011] By adopting the above technical solution and setting rollers, the sliding friction between the mounting frame and the sewage tank is transformed into rolling friction, reducing the friction between the mounting frame and the sewage tank. The rollers slide and are embedded in the guide groove, guiding the slider of the mounting frame, improving the smoothness of the mounting frame's sliding, and improving the reliability of the equipment.

[0013] By adopting the above technical solution, the rotary drive component drives the agitator to rotate, which accelerates the diffusion of sewage from the outlet of the inlet branch pipe to the outer periphery and improves the purification efficiency of the equipment.

[0014] Preferably, the rotary drive assembly includes a gear, a rack, a first driving pulley, a first driven pulley, a first belt body, a second pulley, and a second belt body. The gear is rotatably connected to the mounting frame, and the rotation axis of the gear is parallel to the rotation axis of the agitator. The rack is connected to the sewage tank and meshes with the gear. The first driving pulley is coaxially connected to the gear, and the first driven pulley is coaxially connected to any one of the agitators. The first belt body is sleeved on the outer circumference of the first driving pulley and the first driven pulley. The number of second pulleys is the same as the number of agitators and corresponds one-to-one. The second pulleys are coaxially connected to the agitators, and the second belt body is sleeved on the outer circumference of all the second pulleys.

[0015] By adopting the above technical solution, while the mounting frame slides, it drives the gear to slide. The gear meshes with the rack, drives the gear to rotate, drives the first driving pulley to rotate, drives the first driven pulley to rotate through the first belt, drives the agitator to rotate, drives the second pulley to rotate, drives all the second pulleys to rotate through the second belt, drives all the agitators to rotate, thus realizing the simultaneous movement of the mounting frame and the rotation of the agitator, improving the automation level of the equipment.

[0016] Preferably, the stirring paddle includes a sleeve and blades, the sleeve is coaxially rotatably connected to the outer periphery of the liquid inlet branch pipe, and the blades are connected to the outer periphery of the sleeve, and the blades are spiral in shape.

[0017] By adopting the above technical solution, the blades are spiral-shaped, which realizes the vertical disturbance of sewage in the sewage tank by the stirring paddle, so as to achieve full contact between sewage and microorganisms and improve the purification efficiency of the equipment.

The fixed pipe is fixedly connected to the upper end of the sewage tank, the connecting ring pipe is connected to the mounting frame, one end of the movable pipe is connected to the connecting ring pipe, and the other end of the movable pipe is slidably embedded in the fixed pipe. The outer wall of the movable pipe is in contact with the inner wall of the fixed pipe. The upper end of the liquid inlet branch pipe is connected to the connecting ring pipe, and a plurality of the liquid inlet branch pipes are distributed at intervals along the circumference of the connecting ring pipe.

[0019] By adopting the above technical solution, the main inlet pipe consists of a connecting ring pipe, a moving pipe, and a fixed pipe. The fixed pipe is connected to the external sewage pump and is fixedly connected to the sewage tank, which reduces the possibility of the connection with the sewage pump becoming loose due to the movement of the fixed pipe and improves the reliability of the equipment.

The pressure gauge is connected to the drain pipe and is used to detect the pressure inside the drain pipe. The pressure gauge is used to send a signal to the processor, and the processor is used to receive the signal and control the buzzer to operate.

[0023] By adopting the above technical solution, when a blockage occurs in the main inlet pipe or the branch inlet pipe, the pressure in the main inlet pipe increases, which in turn increases the pressure in the drain pipe. The pressure gauge detects the pressure in the drain pipe and sends a signal to the processor. The processor determines that the pressure is higher than the preset range, controls the buzzer to sound an alarm, and reminds the staff to inspect the equipment, thereby improving the service life of the equipment.

[0026] 2. A horizontal movement component is installed to drive the mounting bracket to slide, thereby moving the main inlet pipe and the branch inlet pipe. This changes the position of the sewage entering the sewage tank from the pipe and disturbs the sewage in the sewage tank through the branch inlet pipe, accelerating the diffusion of sewage and improving the purification efficiency of the equipment.

[0027] 3. As the mounting frame slides, it drives the gear to slide as well. The gear meshes with the rack, driving the gear to rotate. This drives the first driving pulley to rotate, which in turn drives the first driven pulley to rotate via the first belt. This drives the agitator to rotate, which in turn drives the second pulley to rotate. This drives all the second pulleys to rotate via the second belt, which in turn drives all the agitators to rotate. This allows the mounting frame to move while simultaneously driving the agitator to rotate, thus improving the automation level of the equipment. Attached Figure Description
