During the initial filtration, as the volume of wastewater increases, impurities accumulate on the filter screen, inevitably clogging the filter holes. If the filter screen is removed and cleaned each time, the filtration process must be stopped, resulting in low efficiency. Utility Model Content

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] like Figures 1 to 5 As shown, this utility model provides a wastewater purification device for condiment production, including a shell 1, a filtration mechanism 2, an equalization tank 3, an adsorption tank 4, and a drain outlet 5. In this embodiment, the shell 1 supports the filtration mechanism 2, the equalization tank 3, the adsorption tank 4, and the drain outlet 5. Specifically, the shell 1 is a vertical rectangular box made of 304 stainless steel to enhance its corrosion resistance. Condiment production wastewater often contains large particles (1mm-5mm in diameter) such as soybean residue and chili peels. Traditional screens are prone to clogging and require manual cleaning, necessitating timely removal of screen residue. In this embodiment, the filtration mechanism 2 is located at the top of the shell 1, the equalization tank 3 is located below the filtration mechanism 2, and the adsorption tank 4 is located below and to the side of the equalization tank 3 and connected via a pipeline. The drain outlet 5 is located at the bottom of the shell 1 for discharging the final purified water.

[0024] like Figure 2 and Figure 3As shown: The filtration mechanism 2 includes a filter cake chamber 21 and a cake storage chamber 22. The two chambers are separated by a vertical partition 23, which is 50mm lower than the top surface of the shell 1. The residue is conveyed to the cake storage chamber 22 via a conveying mechanism. At the bottom of both the filter cake chamber 21 and the cake storage chamber 22, a filter screen 25 with a 2mm pore size and made of 316L stainless steel woven mesh is installed. This screen is used to filter smaller particles of residue. In this embodiment of the utility model, the conveying mechanism 24 includes the following parts: a transmission belt 241: inclined (30° angle), with filter holes 246 (1mm diameter) evenly opened on the surface, and scrapers 245 (30mm height) arranged at equal intervals are fixed thereon; a first roller 242 and a second roller 243: respectively bearing connected to the two side walls of the housing 1, the first roller 242 is located at the bottom of the filter cake chamber 21, and the second roller 243 is located at the top of the cake storage chamber 22; a first motor 244: drives the first roller 242 through a coupling, and drives the transmission belt 241 to circulate at a speed of 0.2m / s.

[0025] Working process of filter mechanism 2:

[0026] After the wastewater enters the filter cake chamber 21, large suspended particles (such as soybean residue and chili peel) are pushed to the slag storage chamber 22 by the scraper 245. At the same time, the wastewater flows into the equalization tank 3 below after being filtered twice by the filter holes 246 and the filter screen 25. The residue in the slag storage chamber 22 is periodically discharged through the slag discharge port 6 (the slag discharge port 6 is sealed by a bolt-fixed sealing plate).

[0027] like Figure 3 As shown, the regulating tank 3 includes a settling tank 31 and an oil separator 32: the two tanks are arranged adjacent to each other, and the volume of the settling tank 31 is three times that of the oil separator 32. Specifically, the oil scraping mechanism includes: an oil scraping belt 33: horizontally wound around two oil scraping rollers 34, made of oil-resistant rubber; arc-shaped oil plates 36: equidistantly fixed on the surface of the oil scraping belt 33 (200mm spacing), with a plate height of 40mm, forming a semi-circular arc; a second motor 35: driving the oil scraping rollers 34, causing the oil scraping belt 33 to move at a speed of 0.1m / s; a heating mechanism 38: located at the top of the oil separator 32, a coil-type steam heater, maintaining the tank temperature at 35±2℃; and an oil drain port 37: located at the bottom of the oil separator 32 in a conical hopper, equipped with a pneumatic valve.

[0028] Work process:

[0029] The filtered wastewater remains in settling tank 31 for 2 hours, and the floating oil is scraped into oil separator 32 by arc-shaped oil plate 36. Heating mechanism 38 prevents grease from solidifying, and the separated grease is discharged through oil outlet 37. The lower layer of clean water is pumped into adsorption tank 4 through pipeline.

[0030] like Figure 2 and Figure 3As shown: An adsorption mechanism 41 is provided inside the adsorption tank 4. The adsorption mechanism 41 includes three sets of transverse slots 411 and activated carbon adsorption plates 412. The slots 411 are welded to the inner wall of the adsorption tank 4. The three sets of slots 411 are evenly spaced. The dimensions of the adsorption plates 412 are 800mm×500mm×50mm, filled with granular activated carbon (particle size 2mm~4mm), and inserted into the slots 411 through the replacement port 413.

[0031] The replacement port 413 is located on the side wall of the housing 1 and its size matches that of the adsorption plate 412. One end of the pressure plate 414 is hinged to the housing 1, and the other end is tightened with a sealing gasket (made of fluororubber) by a quick-release bolt to ensure no leakage.

[0032] Work process:

[0033] When wastewater flows through the adsorption plate 412, residual organic matter is adsorbed by activated carbon, and the purified water is discharged from the drain outlet 5. When the adsorption is saturated, the pressure plate 414 can be opened to replace the adsorption plate 412.

[0034] This utility model device features dual filtration (filter holes 246 + filter screen 25) to remove >95% of suspended solids (SS) (particle size ≥1mm). It also boasts a high grease separation rate; through the arc-shaped oil plate 36 and the heating mechanism 38, the grease removal rate reaches over 90%.

[0035] After adsorption by activated carbon, the COD of the effluent is reduced to below 50 mg / L, which meets the Class III standard of the Integrated Wastewater Discharge Standard (GB8978~1996).

[0036] Furthermore, the housing 1 can be made of fiberglass instead of stainless steel. The adsorption plate 412 can be replaced with a zeolite adsorption plate or a resin adsorption plate. Parameter adjustment range: the pore size of the filter screen 25 can be adjusted between 1 and 3 mm. The oil scraper belt 33 operates at a speed ranging from 0.05 to 0.3 m / s.

[0037] Extended Implementation Example:

[0038] An ultraviolet disinfection module (not shown in the figure) can be added before the drain outlet 5. An aeration device can be added to the equalization tank 3 to enhance water quality homogenization.

[0039] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
