Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical wastewater treatment, and particularly relates to a comprehensive treatment device for wastewater in a pharmaceutical workshop. Background Art

[0002] The wastewater in the pharmaceutical industry is characterized by complex composition, high organic matter content, high toxicity, deep color, and high salt content. Especially, its biodegradability is very poor, and it is discharged intermittently, belonging to one of the difficult-to-treat industrial wastewaters. Arbitrary discharge will also cause environmental pollution and ecological damage. Usually, impurity treatment and filtration are carried out first, and then subsequent fine treatment is carried out to meet the discharge standards of GB 21904-2008 and GB21906-2008.

[0003] Regarding the treatment of pharmaceutical wastewater, after retrieval, there is a pharmaceutical wastewater treatment device with the prior art publication number CN 117361678 B. In the present invention, a two-way slag scraping mechanism is arranged above the air flotation tank. When the symmetric double-rotation lead screws rotate on the symmetric support vertical plates, at this time, two groups of front and rear symmetric lead screw sliders drive the connecting plate to move from the middle position above the air flotation tank to both left and right sides, so that when the two connecting plates move synchronously, they can drive the vertical scraper and the inclined scraper to move towards both sides of the air flotation tank, thereby facilitating the two vertical scrapers to move towards both left and right sides of the air flotation tank simultaneously to divide, scrape, and push the floating slag, and further preventing excessive floating slag from accumulating on the side of the vertical scraper, which will increase the resistance of the vertical scraper and easily cause the floating slag to accumulate in the air flotation tank. In this solution, by scraping the floating slag by moving both sides of the symmetrically arranged vertical scraper boxes, the resistance can be reduced, but there are also significant drawbacks, that is, there are omissions in the scraping area, and the floating slag in the area between the symmetric vertical scrapers will remain and not be completely removed. At the same time, floating slag will adhere to the inclined scraper and the vertical scraper. If not cleaned, it will enter the wastewater again when the scraper resets.

[0004] There are also the same drawbacks in the prior art publication number CN 220265426 U, a pharmaceutical wastewater pretreatment device. By setting a first adding pipe and a second adding pipe in the reaction chamber to add a flocculant and a coagulant aid, the particulate impurities in the wastewater can be further flocculated. By setting double-layer and staggered air outlet pipes in the contact chamber, the micro-nano bubbles produced in the air dissolver can fully contact the flocculated impurities and make them float. In the separation chamber, the floating impurities are effectively separated from the lower-layer solution by a slag scraper to achieve solid-liquid separation and facilitate subsequent waste liquid treatment. Among them, the slag scraping plate on the slag scraper will scrape the impurities and there will be a situation where the impurities adhere to the slag scraping plate. If not cleaned, it will enter the wastewater again. Summary of the Invention

[0005] The purpose of the present utility model is to overcome the deficiencies in the prior art and provide a comprehensive wastewater treatment device for a pharmaceutical workshop. The scum scraping mechanism can comprehensively scrape the scum on the surface of the wastewater, avoiding omission. At the same time, it can also wash the adhered scum on the scraper in the scum scraping mechanism through the flushing mechanism to keep it clean.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0007] A comprehensive wastewater treatment device for a pharmaceutical workshop, including a treatment tank. A scum scraping mechanism is provided inside the treatment tank, and flushing mechanisms are provided at both ends of the treatment tank. The scum scraping mechanism scrapes the scum of the wastewater in the treatment tank, and then the flushing mechanism flushes and cleans the scum scraping mechanism.

[0008] A pair of partition plates are provided inside the treatment tank to divide the treatment tank into a wastewater chamber and a collection chamber; a first cleaning port, a second cleaning port, and a first drain pipe are provided on the side wall of the treatment tank. The first drain pipe is connected to the wastewater chamber, and the second cleaning port is connected to the collection chamber. Sealing plates that cooperate with each other are provided at the first cleaning port and the second cleaning port to seal the cleaning ports; a first slide rail is provided on one side of the partition plate, and a filter screen that is slidably connected is provided on the first slide rail. The filter screen corresponds to the first cleaning port; a first installation groove is provided at the top of the partition plate, a first chute is provided on one side of the first installation groove, a baffle and a first spring are provided inside the first installation groove, a limiting block is provided on one side of the baffle, and the limiting block is arranged in the first chute. The first spring pushes the baffle to slide along the first chute; a guiding groove is provided on the side wall of the treatment tank.

[0009] The scum scraping mechanism includes a first motor, a reciprocating lead screw, and a scraper; both ends of the reciprocating lead screw are rotatably connected to the side wall of the treatment tank through shafts. The first motor is fixed on one side of the treatment tank through a motor base, and the output shaft of the first motor is connected to one end of the reciprocating lead screw through a shaft; the scraper is threadedly connected to the reciprocating lead screw; guiding shafts are provided on both sides of the scraper, and the guiding shafts are arranged in the guiding groove to facilitate the stable movement of the scraper.

[0010] The flushing mechanism includes a flushing tank, and the flushing tank is fixedly connected to the treatment tank; a first water inlet pipe is provided on one side of the flushing tank, a support frame is provided at the top of the flushing tank, and a flushing groove is provided at the bottom of the flushing tank; a top shaft is provided inside the flushing tank. One end of the top shaft is slidably connected to the flushing tank and the support frame. A limiting plate is provided on the top shaft, and the limiting plate is arranged above the flushing tank. A second spring is sleeved on one end of the top shaft, and the second spring abuts against the limiting plate and the support frame; a sealing block is provided at the other end of the top shaft, and the sealing block is used to block the flushing groove; a conical block fixedly connected is provided on one side of the sealing block.

[0011] Preferably, inclined plates are symmetrically provided at the bottom of the scraper; filter holes are provided on the inclined plates.

[0012] Preferably, through holes are provided on the conical block for water passage, avoiding a large obstruction to the water flow in the flushing groove.

[0013] The beneficial effects of the present utility model compared with the prior art are as follows:

[0014] 1) In this solution, there is a slag scraping mechanism. The first motor cooperates with the reciprocating lead screw to drive the scraper to reciprocate along the guide groove. The scraper pushes the baffle on the partition plate to move down in the first installation groove. After the scraper pushes the floating slag into the collection bin, the baffle quickly resets to prevent the waste water from continuously flowing into the collection bin. Among them, the scraper can comprehensively scrape the floating slag on the surface of the waste water through reciprocating movement to avoid omission. Further, there is an inclined plate on the baffle. During the process of the baffle scraping the floating slag, the inclined plate can not only filter water from the floating slag to reduce resistance, prevent the waste water from being disturbed and entering the collection bin, but also play a role in restricting and confining the floating slag to prevent the floating slag from leaking from the bottom of the baffle when there is a large amount of floating slag.

[0015] 2) In the flushing mechanism, there is a sealing block to close the flushing tank. When the scraper enters the collection bin, the top of the scraper will lift the conical block, and then push the top shaft and the sealing block to rise, opening the closure of the flushing tank, so that the flushing water in the flushing box can rush out and flush the floating slag adhered to the scraper and the inclined plate below, preventing the floating slag from being brought back into the waste water bin when the baffle moves and resets. After the baffle moves away, the sealing block can automatically reset under the push of the second spring to close the flushing tank and cut off the outflow of the flushing water to achieve automatic control. Further, there are several through holes on the conical block for water passage, which can reduce the blocking force of the conical block on the water flow flowing out of the flushing tank and improve the flushing effect in disguise.
