Description

Technical Field

[0001] This utility model relates to the field of wastewater reuse technology, specifically a skid-mounted air flotation wastewater reuse device for paint booths. Background Technology

[0002] Paint booth wastewater is commonly found in industries such as automotive, furniture, and machinery manufacturing. It primarily originates from the circulation within the water curtain cabinets of the paint booth and contains a large amount of paint mist particles and recalcitrant organic matter, making it difficult to treat. Furthermore, the wastewater from paint booths varies between different companies due to differences in their processes, paints, and additives. To reduce water waste and environmental pollution, effective treatment and reuse of paint booth wastewater are necessary. Skid-mounted air flotation wastewater reuse systems are one such solution. These systems are integrated and modular wastewater treatment equipment, with key components mounted on a robust chassis made of angle steel or I-beams, forming a mobile and quickly installable integrated unit.

[0003] In the coagulation tank of an air flotation wastewater recovery device, colloids and fine suspended solids agglomerate into flocs that float on the surface. A belt pulley system drives a chain wheel system, which in turn moves a scraper to move the suspended solids from the top of the coagulation tank into a sedimentation tank. However, the scraper cannot remove the sludge accumulated on the inner walls of the sedimentation tank. Long-term accumulation leads to deterioration of the flocculation effect and turbulent water flow. Therefore, a skid-mounted air flotation wastewater reuse device for paint booths is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a skid-mounted air flotation wastewater reuse device for paint booths, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a skid-mounted air flotation wastewater reuse device for paint booths, comprising:

[0006] An air flotation device, comprising a tank body, a coagulation tank, a pulley assembly, a roller, a chain wheel assembly, and a support plate. The coagulation tank is located in the middle of the tank body. The base of the pulley assembly is fixed to one side of the upper end of the tank body. One side of the roller is rotatably connected to one end of the pulley assembly. The base of the chain wheel assembly is fixed to both sides of the upper end of the tank body. The support plate is fixed to the chain of the chain wheel assembly.

[0007] An anti-stacking assembly includes a fixed plate, a support tube, a spring, a support column, an opening, a limiting block, and a hard scraper. The fixed plate is fixed to both ends of one side of the support plate. One end of the support tube is movably connected to the lower end of the side of the fixed plate. One end of the spring is fixed inside the support tube. The support column is inserted into the support tube and fixed to the other end of the spring. The opening is made on the side of the support tube. One end of the limiting block is fixed to the side of the support column, and the other end is inserted into the opening. The hard scraper is fixed to the other end of the support column away from the spring.

[0008] Furthermore, the anti-accumulation assembly also includes a mounting plate and a reinforcing plate. One side of the mounting plate is fixed to the side of the fixing plate and is fixed to the side of the support plate by screws. The reinforcing plate is fixed between the fixing plate and the mounting plate.

[0009] Furthermore, the air flotation device also includes a soft scraper, which is fixed to the lower side of the support plate by screws.

[0010] Furthermore, the lower end of the hard scraper is flush with the lower end of the soft scraper and is lower than the side opening of the coagulation tank.

[0011] Furthermore, the mounting plate is fixed to the upper side of the soft scraper, and one end of the hard scraper is attached to the inner side wall of the pool.

[0012] Furthermore, it also includes an anti-collision component, which includes a bearing and a torsion spring. The outer ring of the bearing is fixed to the lower side of the fixed plate, and one end of the support tube is fixed in the inner ring of the bearing. The torsion spring is sleeved on the outside of the support tube, with one end fixed to the fixed plate and the other end fixed to the support tube.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes an anti-accumulation component. A chain drives a support plate to move, which in turn moves a soft scraper to scrape suspended solids into the sedimentation tank. Simultaneously, the support plate moves a fixed plate, which in turn moves a support pipe. A spring inside the support pipe pushes a support column, which in turn moves a limiting block within an opening. This pushes a hard scraper on the support column against the inner wall of the tank. As the support plate moves, the hard scraper scrapes down the dirt from the inner wall of the tank. This design prevents dirt accumulation on the inner wall of the tank, ensures flocculation, and avoids water flow turbulence. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 As shown, this utility model is a skid-mounted air flotation wastewater reuse device for a paint booth, comprising:

[0025] The air flotation device includes a tank body 10, a coagulation tank 11, a pulley assembly 12, a roller 13, a chain wheel assembly 14, and a support plate 15. The coagulation tank 11 is located in the middle of the tank body 10. The base of the pulley assembly 12 is fixed to one side of the upper end of the tank body 10. One side of the roller 13 is rotatably connected to one end of the pulley assembly 12. The base of the chain wheel assembly 14 is fixed to both sides of the upper end of the tank body 10. The support plate 15 is fixed to the chain of the chain wheel assembly 14.

[0026] The mounting plate 21 is fixed to the upper side of the soft scraper 16, and one end of the hard scraper 28 is attached to the inner wall of the pool body 10.

[0027] The tank 10 is used for wastewater treatment and includes an equalization tank, a primary sedimentation tank, a coagulation tank 11, a sedimentation tank, a collection tank, a product water tank, and a sludge tank. Wastewater in the collection tank is pumped into the equalization tank, where a dosing device adjusts the water quality and quantity. After being pumped and metered, the wastewater is introduced into the primary sedimentation tank. The sludge at the bottom of the primary sedimentation tank is pumped into the sludge tank, and the liquid at the top flows by gravity into the coagulation tank 11. The dosing device administers chemicals to the coagulation tank 11 to cause colloids and fine suspended solids to coagulate into flocs, which then flow by gravity into the sedimentation tank. The sludge at the bottom of the sedimentation tank is pumped into the sludge tank, and the supernatant flows by gravity into the collection tank. The air flotation machine lifts the clear liquid from the collection tank, and the dosing device administers chemicals to form scum that flows into the sludge tank. The clear water flows by gravity into the product water tank and returns to the water seal tank. The motor drives the pulleys of the belt pulley group 12 to rotate, which in turn drives the roller 13 to rotate. The roller 13 drives the gears in the chain wheel group 14 to rotate, which in turn drives the chain to rotate, thereby moving the support plate 15 and simultaneously moving the soft scraper 16 to scrape the suspended solids into the sedimentation tank.

[0028] The anti-stacking assembly includes a fixed plate 20, a support tube 23, a spring 24, a support column 25, an opening 26, a limiting block 27, and a hard scraper 28. The fixed plate 20 is fixed to both ends of one side of the support plate 15. One end of the support tube 23 is movably connected to the lower end of the side of the fixed plate 20. One end of the spring 24 is fixed to the inside of the support tube 23. The support column 25 is inserted into the support tube 23 and fixed to the other end of the spring 24. The opening 26 is opened on the side of the support tube 23. One end of the limiting block 27 is fixed to the side of the support column 25, and the other end is inserted into the opening 26. The hard scraper 28 is fixed to the other end of the support column 25 away from the spring 24.

[0029] The anti-accumulation assembly also includes a mounting plate 21 and a reinforcing plate 22. One side of the mounting plate 21 is fixed to the side of the fixing plate 20 and is fixed to the side of the support plate 15 by screws. The reinforcing plate 22 is fixed between the fixing plate 20 and the mounting plate 21.

[0030] The air flotation device also includes a soft scraper 16, which is fixed to the lower side of the support plate 15 by screws;

[0031] The lower end of the hard scraper 28 is flush with the lower end of the soft scraper 16 and is lower than the side opening of the coagulation tank 11.

[0032] The fixing plate 20 provides support, the mounting plate 21 connects the fixing plate 20 to the support plate 15, the reinforcing plate 22 provides reinforcement, the support tube 23 provides support, the spring 24 has a telescopic function, the support column 25 provides connection, the opening 26 and the limiting block 27 provide limiting to prevent the support column 25 from rotating axially around the support tube 23, and the hard scraper 28 is used to scrape the dirt from the inner wall of the pool 10.

[0033] Working principle:

[0034] The fixing plate 20 is fixed to the support plate 15 by the mounting plate 21 and screws. The chain drives the support plate 15 to move, which in turn drives the soft scraper 16 to move, scraping the suspended solids into the sedimentation tank. At the same time, the support plate 15 drives the fixing plate 20 to move, and the fixing plate 20 drives the support tube 23 to move. The spring 24 in the support tube 23 pushes the support column 25, and at the same time drives the limit block 27 to move in the opening 26, pushing the hard scraper 28 on the support column 25 towards the inner wall of the tank body 10. As the support plate 15 moves, the hard scraper 28 scrapes the dirt off the inner wall of the tank body 10.

[0035] This step prevents the accumulation of dirt on the inner wall of the pool 10, ensures the flocculation effect, and avoids water flow turbulence.

[0036] Please see Figure 2-3 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The anti-collision assembly includes a bearing 30 and a torsion spring 32. The outer ring of the bearing 30 is fixed to the lower side of the fixed plate 20, and one end of the support tube 23 is fixed in the inner ring of the bearing 30. The torsion spring 32 is sleeved on the outside of the support tube 23, and one end is fixed to the fixed plate 20 and the other end is fixed to the support tube 23.

[0038] The anti-collision assembly also includes a fixing plate 31, which is fixed to the other end of the support tube 23 away from the fixing plate 20, and one end of the torsion spring 32 is fixed to the fixing plate 31.

[0039] The bearing 30 facilitates the rotation of the support tube 23, the fixed plate 31 serves as a connection, and the torsion spring 32 has a reset function.

[0040] Working principle:

[0041] As the support plate 15 moves, it drives the anti-accumulation component to move. When the support plate 15 and the soft scraper 16 move to the sedimentation tank opening, the soft scraper 16 scrapes the suspended solids into the sedimentation tank, while the hard scraper 28 is blocked by the tank opening. As the support plate 15 moves, the hard scraper 28 drives the support column 25 and the support pipe 23 to rotate around the bearing 30. After the hard scraper 28 moves past the sedimentation tank opening, it rotates in the opposite direction to return to its original position under the action of the torsion spring 32.

[0042] This step prevents the hard scraper 28 from being damaged when it hits the opening of the sedimentation tank.
