Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automatic dosing device for wastewater treatment. Background Technology
[0002] Wastewater treatment refers to the treatment of wastewater through physical, chemical, and biological methods to purify water quality, reduce pollution, and potentially achieve wastewater recycling and reuse. Wastewater treatment is widely used in construction, agriculture, transportation, and many other fields, aiming to bring wastewater up to the required quality for discharge into a water body or for reuse. The main methods of wastewater treatment include physical treatment, chemical treatment, and biological treatment. Physical treatment removes insoluble pollutants and suspended solids from wastewater through mechanical or physical barriers. Chemical treatment removes or transforms harmful substances in wastewater through chemical reactions caused by the addition of chemical substances. Biological treatment utilizes the metabolic activity of microorganisms to convert organic pollutants into harmless substances.
[0003] In the wastewater treatment process, the dosing of chemicals is usually done by the staff themselves. However, the staff need to repeatedly add the powder during the treatment process to ensure that the amount of powder added does not exceed the acceptable error range. The whole process is time-consuming and labor-intensive, resulting in a heavy workload for the staff. Utility Model Content
[0004] To achieve the above objectives, this utility model proposes an automatic dosing device for sewage treatment.
[0005] The technical solution of this utility model is implemented as follows: An automatic dosing device for sewage treatment includes a treatment box, a dosing mechanism on the treatment box, a fixed box fixedly connected to the top of the treatment box, a connecting box fixedly connected to one side of the fixed box, a dosing port on the top of the connecting box, a first motor fixedly connected to the bottom of the connecting box, an electric telescopic rod fixedly connected to the top of the fixed box, a vacuum cleaner fixedly connected to one end of the fixed box, a storage box slidably connected to the bottom of the vacuum cleaner, a suction tube fixedly connected to the top of the vacuum cleaner, a second motor fixedly connected to the other end of the fixed box, a spiral auger rotatably connected inside the connecting box, a baffle fixedly connected inside the fixed box, a dust suction cover fixedly connected to the bottom of the electric telescopic rod, a cavity inside the fixed box, a first rotating rod rotatably connected inside the cavity of the fixed box, a connecting block fixedly connected to the outer surface of the first rotating rod, and a measuring scale fixedly connected to one side of the connecting block.
[0006] Preferably, the first motor is fixedly connected to the spiral auger, the fixed box has a through hole and the spiral auger is located therein, the through hole on the fixed box is connected to the cavity on the fixed box, and the spiral auger is rotatably connected to the fixed box.
[0007] Preferably, the straw is retractable.
[0008] Preferably, one side of the baffle is an inclined surface, and the baffle is located below the connection between the upper cavity of the fixed box and the upper through hole of the fixed box.
[0009] Preferably, the cavity on the fixed box is convex, the second motor is fixedly connected to the first rotating rod, one side of the measuring scale is inclined, and a pressure sensor is inside the measuring scale.
[0010] Preferably, the processing box is equipped with a stirring mechanism, a third motor is fixedly connected to the top of the processing box, a second rotating rod is fixedly connected to the bottom of the third motor, and a stirring rod is fixedly connected to the outer surface of the second rotating rod.
[0011] Preferably, a feed pipe is fixedly connected to the top of the processing box, a discharge pipe is fixedly connected to the bottom of the processing box, and a support leg is fixedly connected to the bottom of the processing box.
[0012] Preferably, the top of the processing box is provided with a feeding port, which is connected to the cavity on the upper part of the fixed box.
[0013] This utility model has the following beneficial effects:
[0014] 1. This automatic dosing device for wastewater treatment uses a first motor to drive a spiral auger, which in turn conveys the powdered chemicals into the cavity of a fixed tank. The powder then slides down the inclined surface of a baffle onto a measuring scale. When the pressure sensor inside the measuring scale detects that the powder has accumulated to a set amount, it sends a signal to stop the spiral auger from conveying the powder. Then, a second motor drives a first rotating rod to rotate, which in turn rotates the connecting block and the measuring scale. The powdered chemicals on the measuring scale slide down as it rotates, falling into the wastewater inside the treatment tank through the feeding port. This eliminates the need for manual dosing, allowing for automatic and quantitative dosing, thus reducing the workload of the staff.
[0015] 2. In this wastewater treatment automatic dosing device, even when the spiral auger stops conveying the powder, some powder may still slip onto the measuring scale, potentially exceeding the set tolerance for powder quantity. At this point, the pressure sensor sends a signal to activate the electric telescopic rod and vacuum cleaner. The electric telescopic rod extends downwards to touch the powder and then stops. The vacuum cleaner then uses its suction pipe to remove the powder from under the dust hood until the powder on the measuring scale is reduced to within the set tolerance range. This ensures that the dosage is always within the acceptable tolerance range. Attached Figure Description

[0026] Furthermore, the first motor 204 is fixedly connected to the spiral auger 210, the fixed box 201 has a through hole, and the spiral auger 210 is located in the hole. The through hole on the fixed box 201 is connected to the cavity 213 on the fixed box 201, and the spiral auger 210 is rotatably connected to the fixed box 201.
[0027] By adopting the above technical solution, the first motor 204 drives the spiral auger 210 to rotate, and the spiral auger 210 conveys the medicine powder through the through hole on the fixed box 201 into the cavity 213 on the fixed box 201.
[0028] Furthermore, straw 208 is retractable.
[0029] By adopting the above technical solution, the straw 208 is made telescopic, which allows the straw 208 to extend its distance and avoids the straw 208 being too short during movement.
[0030] Furthermore, one side of the baffle 211 is inclined, and the baffle 211 is located below the connection between the upper cavity 213 of the fixed box 201 and the upper through hole of the fixed box 201.
[0031] By adopting the above technical solution, the powder in the cavity 213 of the fixed box 201 can slide down the inclined surface of the baffle 211.
[0032] Furthermore, the cavity 213 on the fixed box 201 is convex, the second motor 209 is fixedly connected to the first rotating rod 215, one side of the measuring scale 214 is inclined, and the measuring scale 214 contains a pressure sensor.
[0033] By adopting the above technical solution, the measuring scale 214 is located in the middle of the upper and lower spaces of the cavity 213 in the fixed box 201, so that the powder only slides onto the measuring scale 214. One side of the measuring scale 214 is inclined, which facilitates the second motor 209 to drive the measuring scale 214 to rotate through the first rotating rod 215.

[0038] Furthermore, a feeding port 7 is provided on the top of the processing box 1, and the feeding port 7 on the processing box 1 is connected to the cavity 213 on the fixed box 201.
[0039] By adopting the above technical solution, the powder in the cavity 213 of the fixed box 201 can be sent into the treatment box 1 through the feeding port 7 on the treatment box 1 to mix with the sewage.
[0040] Working principle: The powder is poured into the connecting box 202 through the inlet 203. This starts the first motor 204, which drives the spiral auger 210 to rotate. The spiral auger 210 then conveys the powder into the cavity 213 on the fixed box 201. After reaching the cavity 213, the powder slides down the inclined surface of the baffle 211 onto the measuring scale 214. When the pressure sensor inside the measuring scale 214 detects that the powder has accumulated to a set amount, the pressure sensor... The signal is sent out to stop the first motor 204 from rotating, so that the spiral auger 210 stops conveying the powder. However, after the spiral auger 210 stops conveying, some powder will still slip onto the measuring scale 214, which may cause the powder on the measuring scale 214 to exceed the set allowable error for the amount of powder. At this time, the pressure sensor sends out a signal to activate the electric telescopic rod 205 and the vacuum cleaner 206. The electric telescopic rod 205 will extend the suction hood 212 downwards until it touches the powder and then stops. The vacuum cleaner 206 then uses the suction pipe 208 to... The vacuum cleaner 206 sucks up the powder under the dust cover 212, controlling the suction power to prevent the powder from being sucked up too quickly. The vacuum cleaner 206 then transports the sucked-up powder to the storage box 207 for storage, making it easy to reuse. Once the powder on the measuring scale 214 has decreased to a level that can be tolerated by the set powder amount, the vacuum cleaner 206 stops sucking up, the electric telescopic rod 205 resets the dust cover 212, and the pressure sensor sends a signal to activate the second motor 209, which then drives the first motor... When the first rotating rod 215 rotates, it drives the connecting block 216 and the measuring scale 214 to rotate. The powder on the measuring scale 214 slides down as the measuring scale 214 rotates. The falling powder falls into the sewage in the treatment tank 1 through the feeding port 7 on the treatment tank 1. Then, the third motor 301 is started. The third motor 301 drives the second rotating rod 302 to rotate. The second rotating rod 302 drives the stirring rod 303 to stir the powder and sewage in the treatment tank 1, so that the powder and sewage are fully mixed.
