An oily wastewater pretreatment device that facilitates chemical dosing

Abstract

This utility model relates to the field of wastewater technology and discloses a pretreatment device for oily wastewater that facilitates drug dosing. The device includes: a cylindrical body; a switching section located inside the cylindrical body; and a metering section located at the top of the cylindrical body. The drug is placed inside a storage tank and then transported downwards through a conveying pipe into the metering cylinder. A second motor drives two metering plates to rotate. When metering plate one no longer obstructs the bottom of the metering cylinder, the drug inside the cylinder falls, thus achieving a metered drug output. As metering plates one and two rotate, when metering plate one obstructs the bottom of the metering cylinder, metering plate two does not obstruct the bottom of the conveying pipe, allowing the drug to be transported into the metering cylinder. By adjusting the height of metering plate two, the sliding cylinder slides upwards under the transmission of an "L"-shaped connecting rod, achieving adjustable metering transmission.

Description

Technical Field

[0001] This utility model relates to the field of wastewater technology, specifically to a pretreatment device for oily wastewater that is easy to administer chemicals. Background Technology

[0002] Oily wastewater refers to wastewater containing grease (including mineral oil, animal and vegetable oils, etc.). It is a common industrial wastewater or domestic sewage generated during the production and operation of many industries such as oil extraction, processing, transportation, machinery manufacturing, food processing, and catering services.

[0003] In the dosing stage, traditional equipment is inconvenient for continuous pretreatment of wastewater. It often stops the wastewater transmission and then weighs and adds the chemicals, resulting in intermittent wastewater discharge. In addition, too much or too little chemicals will have an adverse effect on the wastewater treatment effect. Too much chemicals will not only waste chemicals and increase treatment costs, but may also cause secondary pollution to the environment. Too little chemicals will not be able to effectively remove oil and impurities from the wastewater, resulting in the treated wastewater failing to meet the discharge standards. Utility Model Content

[0025] Example 1:

[0026] Given that existing technologies often rely on traditional devices that are inconvenient for continuous wastewater pretreatment, requiring the wastewater flow to be stopped before the chemicals are weighed and added, resulting in intermittent wastewater discharge, this invention provides a preferred embodiment of an oily wastewater pretreatment device that facilitates chemical dosing. Figure 1-5 As shown: An oily wastewater pretreatment device for easy dosing includes: a cylinder 1; a switching part 2 disposed inside the cylinder 1; a metering part 3 disposed at the top of the cylinder 1; and a bottom leg 4 fixedly connected to the bottom of the cylinder 1.

[0028] A limiting frame 215 is fixedly connected to the top of the rotating disk 214. A collection box 216 is slidably connected between the limiting frame 215 and the cylinder 1. The collection boxes 216 are equidistantly arranged around the circumference. A transmission port is opened on the outer wall of the rotating disk 214. The transmission ports are symmetrically arranged. An electric valve 217 is slidably connected to the inner wall of the transmission port.

[0029] Furthermore, in this embodiment, the collection box 216 is slidably mounted on the top of the rotating disk 214 along the inner wall of the cylinder 1 and the inner wall of the limiting frame 215, so that the transmission port is aligned with the feed pipe 211 and the discharge pipe 212. The drive motor 218 causes the rotating disk 214 to rotate only 90 degrees each time. When the feed pipe 211 is aligned with the transmission port, the electric valve 217 opens the transmission port. When the discharge pipe 212 is aligned with the transmission port, the electric valve 217 opens the transmission port, so that sewage continuously enters the interior of the collection box 216. Subsequently, the rotation of the collection box 216 facilitates the mixing of sewage and medicine inside the collection box 216.

[0030] Example 2:

[0031] Based on Embodiment 1, a preferred embodiment of the oily wastewater pretreatment device for easy dosing provided by this utility model is as follows: Figure 1-5 As shown: The quantitative part 3 includes: an electric telescopic frame 311, which is fixedly connected to the top of the cylinder 1; a fixed frame 314, which is fixedly connected to the top of the cylinder 1; a motor 315, which is fixedly connected to the top of the cylinder 1; and a feed hopper 323, which is connected to the top of the cylinder 1.

[0032] The top of the electric telescopic frame 311 is fixedly connected to a storage box 312. The bottom of the storage box 312 is provided with a discharge port. The bottom of the discharge port is connected to a conveying pipe 313. One end of the fixed frame 314 is fixedly connected to a metering cylinder 320, which is compatible with the feeding hopper 323.

[0033] The output end of motor 2 315 is fixedly connected to metering plate 1 316. The top of metering plate 1 316 is fixedly connected to telescopic column 1 317. The telescopic end of telescopic column 1 317 is fixedly connected to metering plate 2 318. Metering plate 2 318 is adapted to conveying pipe 313. An annular groove is opened at the bottom of metering plate 2 318. Telescopic column 2 319 is set between metering plate 2 318 and storage box 312. The telescopic end of telescopic column 2 319 is rotatably connected to the top of metering plate 2 318. The other end of telescopic column 2 319 is fixedly connected to one side of storage box 312 through connecting seat.

[0034] The top of the metering cylinder 320 is provided with a sliding groove, and a sliding cylinder 321 is slidably connected inside the sliding groove. An "L"-shaped connecting rod 322 is fixedly connected to the outer wall of the sliding cylinder 321, and the other end of the "L"-shaped connecting rod 322 is slidably connected to the annular groove.

[0035] Furthermore, in this embodiment, the medicine is placed inside the storage box 312, and then the medicine is transferred downward from the conveying pipe 313 to the inside of the metering cylinder 320. The second driving motor 315 drives the first metering plate 316 and the second metering plate 318 to rotate. When the first metering plate 316 no longer obstructs the bottom of the metering cylinder 320, the medicine inside the metering cylinder 320 falls, thereby achieving the purpose of metered output of medicine. As the first metering plate 316 and the second metering plate 318 rotate, when the first metering plate 316 obstructs the bottom of the metering cylinder 320, the second metering plate 318 does not obstruct the bottom of the conveying pipe 313, thereby achieving the purpose of transferring medicine into the inside of the metering cylinder 320. By adjusting the height of the second metering plate 318, the sliding cylinder 321 slides upward under the transmission of the "L"-shaped connecting rod 322, thereby achieving the purpose of adjusting the medicine capacity inside the metering cylinder 320, thus achieving the purpose of adjustable metered transmission.

[0036] In use, firstly, the collection box 216 is slidably mounted on top of the rotating disk 214 along the inner wall of the cylinder 1 and the inner wall of the limiting frame 215, so that the transmission port is aligned with the feed pipe 211 and the discharge pipe 212. The drive motor 218 is then used to rotate the rotating disk 214 only 90 degrees at a time. When the feed pipe 211 is aligned with the transmission port, the electric valve 217 is opened to open the transmission port. When the discharge pipe 212 is aligned with the transmission port, the electric valve 217 is opened to open the transmission port, thus allowing wastewater to continuously enter the collection box 216. The subsequent rotation of the collection box 216 also facilitates the mixing of wastewater and medicine inside the collection box 216. Secondly, the medicine is placed inside the storage tank 312, and then the medicine is transferred downwards from the conveying pipe 313 to the inside of the metering cylinder 320. The second driving motor 315 drives the first metering plate 316 and the second metering plate 318 to rotate. When the first metering plate 316 no longer obstructs the bottom of the metering cylinder 320, the medicine inside the metering cylinder 320 falls, thereby achieving the purpose of metered output of medicine. As the first metering plate 316 and the second metering plate 318 rotate, when the first metering plate 316 obstructs the bottom of the metering cylinder 320, the second metering plate 318 does not obstruct the bottom of the conveying pipe 313, thereby achieving the purpose of transferring medicine into the metering cylinder 320. By adjusting the height of the second metering plate 318, the sliding cylinder 321 slides upward under the transmission of the "L"-shaped connecting rod 322, thereby achieving the purpose of adjusting the medicine capacity inside the metering cylinder 320, thus achieving the purpose of adjustable metered transmission.
