Description

Technical Field

[0001] This utility model relates to the technical field of industrial wastewater treatment equipment, specifically to a leather production wastewater treatment equipment. Background Technology

[0002] With the rapid development of the leather industry in recent years, leather wastewater has become one of the important sources of pollution. The wastewater generated in the leather production process mainly comes from the pre-tanning section (including soaking and fleshing, hair removal and liming, deliming and softening, and chemical processes), the tanning section (including pickling and tanning processes), and the finishing section (including retanning, neutralization, dyeing, and fatliquoring processes).

[0003] Existing wastewater treatment equipment for leather production filters impurities in the water during the initial treatment stage using filter plates. However, during the filtration process, impurities accumulate on the filter plates, causing the mesh to become clogged, which slows down the water flow and ultimately prevents the filtration process from continuing normally.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0005] This utility model proposes a wastewater treatment device for leather production, which solves the problem in existing leather production wastewater treatment devices that, during the initial treatment of wastewater, use filter plates to filter impurities in the water. However, during the filtration process, impurities accumulate on the filter plates, causing mesh blockage and thus slowing down the water flow.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figures 1-4 As shown, this embodiment proposes a wastewater treatment device for leather production, including...

[0032] A pair of filter layers 3, both of which are disposed inside the outer casing 1;

[0033] The flushing and scraping assembly 5 is disposed inside the housing 1;

[0034] A pair of suction and collection devices 4 and a collection component 6 are provided. The suction and collection devices 4 are both disposed on the outer surface of the housing 1, and the collection component 6 is disposed on the top of the housing 1.

[0035] The rinsing and scraping assembly 5 includes a pair of pipes 5-1, which are respectively connected to the two ends inside the housing 1. Several rinsing nozzles 5-2 are provided on the surface of the pipes 5-1. A water inlet pipe 5-3 is provided on the side surface of the housing 1, which is connected to the pipes 5-1. A drive shaft 5-4 is provided on the side surface of the housing 1. The drive shaft 5-4 is rotated by a motor. A pair of drive gears 5-5 are provided on the drive shaft 5-4. A pair of inner shafts 5-6 are rotatably connected inside the housing 1. A driven gear 5-7 is provided at one end of the inner shaft 5-6. The driven gear 5-7 meshes with the drive gear 5-5. Both ends of the inner shaft 5-6 are fixed with elastic telescopic rods 5-8. A scraper 5-9 is connected to the output end of the elastic telescopic rods 5-8.

[0036] In this embodiment, a rinsing and scraping assembly 5 is designed to improve the cleaning effect of the filter layer 3. Two pairs of pipes 5-1 are provided inside the outer shell 1. The pipes 5-1 are located on one side of the filter layer 3. Multiple rinsing nozzles 5-2 are provided on the pipes 5-1. A water inlet pipe 5-3 is installed on the outside and connected to the pipes 5-1. A water supply device can be connected to rinse the filter layer 3 through the rinsing nozzles 5-2. Two inner shafts 5-6 are also rotatably connected inside. The outer end of the inner shaft 5-6 is provided with a driven gear 5-7. A drive shaft 5-4 controlled by a motor is installed on the outer surface of the outer shell 1. Two drive gears 5-5 are provided on the drive shaft 5-4 and mesh with the driven gears 5-7. The inner shaft 5-6 can be rotated by the drive shaft 5-4. Both ends of the inner shaft 5-6 are provided with elastic telescopic rods 5-8 and a scraper 5-9 is connected to the output end. When the inner rods rotate, the scraper 5-9 can clean the surface of the filter layer 3 and drive it upward. During the scraping process, the elasticity of the elastic telescopic rods 5-8 can be used to push and extend the rods to maintain a close fit.

[0037] Furthermore, the collection component 6 includes a fixed base 6-1, which is disposed on the outer surface of the housing 1. A pair of telescopic cylinders 6-2 are disposed on the fixed base 6-1. The output end of the telescopic cylinders 6-2 is connected to a top frame. The bottom of the top frame is connected to a collection pipe 6-45-1. Several suction holes 6-5 are opened on the side surface of the collection pipe 6-45-1. The collection pipe 6-45-1 is connected to the output end of the suction collection device 4.

[0038] In this embodiment, in order to achieve the effect of collecting and cleaning small filter materials, a collection component 6 is designed. A fixed base 6-1 is provided on the outer surface of the housing 1 and two telescopic cylinders 6-2 are installed. The output end of the telescopic cylinder 6-2 is connected to a top frame. The bottom of the top frame is provided with two collection pipes 6-45-1 and connected to the suction collection device 4. The surface of the collection pipes 6-45-1 is provided with suction holes 6-5, which can generate suction force to suck up the scraped filter materials.

[0039] Furthermore, both filter layers 3 have a curved transition structure, and scrapers 5-9 are in contact with the surface of filter layer 3.

[0040] In this embodiment, the curved transition structure, in conjunction with the scraper 5-9, allows the filtered material to be concentrated and cleaned to the top.

[0041] Furthermore, a baffle 7 is provided on the surface of the scraper 5-9, and the baffle 7 is at a 90° angle to the scraper 5-9.

[0042] In this embodiment, by providing a baffle 7, the filter material can be blocked on the surface of the scraper 5-9, preventing it from sliding and falling off.

[0043] Furthermore, both the drive gear 5-5 and the driven gear 5-7 are bevel gears.

[0044] In this embodiment, a bevel gear structure is used to achieve the effect of simultaneously controlling the rotation of two inner shafts 5-6.

[0045] Furthermore, the rinsing nozzle 5-2 has a certain tilt angle, and the angle of the rinsing nozzle 5-2 is close to the curvature of the surface of the filter layer 3.

[0046] In this embodiment, by using an inclined angle in conjunction with the mist spraying method of the rinsing nozzle 5-2, the entire position of the filter layer 3 can be fully covered, ensuring the rinsing effect.

[0047] In the wastewater treatment process, inlet and outlet pipes 2 are used to circulate wastewater, and two filter layers 3 are used to filter wastewater. The two filter layers 3 have different densities, and the filtered foreign matter is retained on the surface of the filter layer 3. When cleaning is required, first open the inlet pipe 5-3 and rinse the filter layer 3 through the flushing nozzle 5-2. Then start the drive shaft 5-4 to control the two inner shafts 5-6 to rotate synchronously. During the rotation, the scraper 5-9 cleans the surface of the filter layer 3. After cleaning, it stops at the top of the outer shell 1. Then start the telescopic cylinder 6-2 to control the collection pipe 6-45-1 to descend and start the suction collection device 4. The filtered matter can be cleaned through the suction hole 6-5.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
