A sewage treatment dosing device

Abstract

This utility model discloses a wastewater treatment dosing device, including a tank and a controller. A support base is fixedly connected to the top of the tank, and the controller is fixedly installed on one side of the top of the support base. A dosing tank is fixedly connected to the top of the support base, and an injection pump is installed at both ends of the dosing tank. A connecting pipe is fixedly connected to both output ends of the injection pump. In this utility model, through the support base, dosing tank, injection pump, connecting pipe, bearing seat, through hole, stirring pipe, water baffle, pipe sleeve, and belt drive assembly, the agent can be drawn from the dosing tank and then injected into the wastewater by stirring. This allows the agent to be distributed more evenly in the water and achieves the expected mixing effect for deep-seated pollutants. Secondly, the water baffle is set in the direction of rotation, which can form a negative pressure zone at adjacent through holes during stirring, thereby reducing the outlet pressure of the agent.

Description

Technical Field

[0001] This utility model relates to the field of chemical dosing devices, and in particular to a wastewater treatment chemical dosing device. Background Technology

[0002] Chemical dosing in wastewater treatment is to improve purification efficiency. Wastewater contains various pollutants, such as organic matter, suspended solids, grease, heavy metal ions, nitrogen, and phosphorus. Without chemical treatment, these pollutants are difficult to remove completely and can even cause serious environmental pollution. Therefore, wastewater treatment requires auxiliary chemical dosing. The chemicals react chemically with the wastewater, converting harmful substances into harmless ones, thus achieving better purification results.

[0003] A prior art patent (CN222556604U) discloses a wastewater treatment dosing device, comprising two slide rails respectively installed on both ends of the top surface of a wastewater tank. Each slide rail has a sliding frame on its top surface, and a support plate is fixed between the two sliding frames. A storage tank is fixedly installed in the middle of the support plate. In this invention, during dosing, a stirring motor is controlled to rotate, driving a transmission rod to rotate inside the storage tank. The rotation of the transmission rod causes a stirring blade fixedly installed at the bottom to rotate accordingly.

[0004] In actual use, the wastewater treatment agent is only sprayed on the surface of the wastewater. Due to the lack of a mixing mechanism, the agent is unevenly distributed in the water, making it difficult to achieve the expected treatment effect, especially for deep pollutants.

[0005] Therefore, improvements are proposed. Utility Model Content

[0006] This utility model is a wastewater treatment dosing device proposed to overcome the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a sewage treatment dosing device, comprising a tank and a controller, wherein a support base is fixedly connected to the top of the tank, and the controller is fixedly installed on one side of the top of the support base, a dosing tank is fixedly connected to the top of the support base, and an injection pump is installed at both ends of the dosing tank, and a connecting pipe is fixedly connected to both output ends of the injection pump.

[0008] Both ends of the pool are provided with bearing seats that penetrate into the interior, and the bearing seats are fixedly connected to the pool. A shaft tube is sealed and rotated between the two bearing seats. Multiple stirring tubes are fixedly sleeved on the outer surface of the shaft tube. Multiple through holes penetrating into the interior are opened on both sides of the outer surface of the multiple stirring tubes. Multiple water-blocking blocks are fixedly connected to both sides of the outer surface of the multiple stirring tubes, and the water-blocking blocks match the adjacent through holes.

[0009] The outer surface of the shaft tube is symmetrically sealed with two sleeves, and the sleeves are fixedly connected to the adjacent connecting tubes.

[0010] A belt drive assembly is installed at one end of the shaft tube.

[0011] Furthermore, both of the aforementioned injection pumps include servo motors, which are fixedly mounted on the top of the dispensing container. A screw is fixedly connected to the drive end of the servo motor, and a movable plate is threaded onto the outer surface of the screw. Two pistons are symmetrically fixedly connected to the bottom of the movable plate. A fixed cylinder is sealed on the outer surface of the pistons of both pistons. A three-way solenoid valve is fixedly connected to the bottom of both fixed cylinders, and the remaining two ports of the three-way solenoid valve are fixedly connected to the connecting pipe and the dispensing container, respectively. The three-way solenoid valve facilitates pipeline switching.

[0012] Furthermore, the shaft tube includes a tube body, and the tube body is rotatably connected to two bearing seats in a sealed manner. The stirring tube is fixedly connected to the tube body. The outer surface of the tube body is provided with two sets of water inlet holes that penetrate into the interior. Each set of water inlet holes has multiple holes arranged in a ring. The bearing seats provide support for the tube body, which is conducive to the installation of the tube shaft.

[0013] Furthermore, both of the aforementioned sleeves include a fixed sleeve, which is sealed and fitted onto the outer surface of the pipe body. Each set of water inlet holes is located on the inner side of the adjacent fixed sleeve. A support rod is fixedly connected between the fixed sleeve and the pool body. An installation pipe is fixedly connected to the top of the fixed sleeve, and the installation pipe is fixedly connected to the connecting pipe. The support rod provides support for the fixed sleeve, and the fixed sleeve also provides support for the pipe body, thus preventing deformation of the pipe body.

[0014] Furthermore, the belt drive assembly includes a drive motor, which is fixedly installed on one side of the pool body. A small pulley is fixedly connected to the drive end of the drive motor. A transmission belt is sleeved on the outer surface of the small pulley, and a large pulley abuts against the inner surface of the transmission belt. The large pulley is fixedly sleeved on the outer surface of the tube body. The small pulley drives the large pulley to rotate, which has a deceleration effect and increases the torque at the same time.

[0015] Furthermore, a water outlet pipe is fixedly connected to one bottom side of the outer surface of the pool body, and the water outlet pipe is used to discharge the treated sewage.

[0016] Furthermore, a liquid level sensor is fixedly connected to the bottom center of the support base for detecting the liquid level.

[0017] The beneficial effects of this utility model are:

[0018] In use, this wastewater treatment dosing device, through a support base, a dosing tank, an injection pump, a connecting pipe, a bearing seat, a through hole, a stirring pipe, a water-blocking block, a pipe sleeve, and a belt drive assembly, allows the agent to be drawn from the dosing tank and then injected into the wastewater by stirring. This ensures that the agent is distributed more evenly in the water and achieves the expected mixing effect for deep-seated pollutants. Secondly, the water-blocking block is positioned in the direction of rotation, which creates a negative pressure zone at adjacent through holes during stirring, thereby reducing the outlet pressure of the agent.

[0030] Multiple through holes 19 are provided on both sides of the outer surface of multiple stirring tubes 11, and multiple water-blocking blocks 20 are fixedly connected to both sides of the outer surface of multiple stirring tubes 11. The water-blocking blocks 20 are matched with the adjacent through holes 19. The water-blocking blocks 20 are welded to the outer surface of the stirring tubes 11 to ensure the connection strength.

[0031] Two sleeves are symmetrically sealed on the outer surface of the shaft tube, and the sleeves are fixedly connected to the adjacent connecting pipe 4.
