Description

Technical Field

[0001] This invention relates to the technical field of environmental protection equipment, and in particular to a device for treating air flotation scum in wastewater from garment factories. Background Technology

[0002] In textile and garment factories and other processing industries, a large amount of wastewater is generated due to the dyeing and washing of fabrics. This wastewater usually contains a large amount of organic matter such as fibers, dyes, and greases, which poses a significant threat to the environment. When treating these organic impurities, air flotation is usually used to separate the impurities from the wastewater to purify it. The separated impurities are then further separated from the wastewater by filter press. However, when conventional filter presses filter impurities, the impurities are characterized by high fluidity, high water content, and small particle size. As a result, the impurities tend to cover the filter screen, causing it to become clogged, affecting water flow, and thus impacting the filtration effect. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a device for treating air flotation scum in wastewater from garment factories, the specific technical solution of which is as follows:

[0004] A flotation and scum treatment device for wastewater from a garment factory includes a tank and a rotating body, wherein the rotating body is vertically located inside the tank and can rotate to treat impurities inside the tank.

[0005] The barrel body consists of a lower cone and an upper column, with a discharge channel on the column for discharging impurities after pressure filtration.

[0006] The rotating body consists of a lower vertical tube and an upper filter cylinder. A centrifugal plate is provided on the vertical tube, and multiple spiral plates for pushing impurities are provided on the filter cylinder. The top of the spiral plates is provided with a pressure ring that can slide on the filter cylinder and squeeze the impurities conveyed by the spiral plates.

[0007] Furthermore, the filter cartridge is composed of a lower first conical surface, a middle second conical surface, and an upper cylindrical surface, with the spiral plate located on the second conical surface and the pressure ring located on the cylindrical surface;

[0008] Each spiral plate has a vertical plate at its upper end, which extends to the cylindrical surface and slides through the pressure ring to guide it.

[0009] Furthermore, the filter cartridge has a mounting plate on its cylindrical surface, and the mounting plate is connected to the pressure ring by a spring. The spring has a guide post for guiding the spring, and the guide post slides through the mounting plate.

[0010] Furthermore, the centrifuge plate is arranged along the inclined direction of the cone of the barrel, and a specified distance is left between the centrifuge plate and the inner wall of the cone. The centrifuge plate is connected to the vertical pipe by a connecting rod.

[0011] Furthermore, a water collection tank is provided at the bottom of the barrel, and the bottom of the vertical pipe passes through the barrel and is inserted into the water collection tank, thereby connecting the filter cartridge to the water collection tank through the vertical pipe. The water collection tank is connected to the conical part of the barrel through a water guide pipe. A drain pipe is provided at the bottom of the water collection tank, a feed pipe is provided at the bottom of the barrel, and an air vent pipe is provided at the top of the filter cartridge.

[0012] Furthermore, a rotating ring is provided at the end of the vertical pipe inside the water collection tank, and multiple levers are inclined on the rotating ring, with the multiple levers distributed in a ring.

[0013] Furthermore, the drain pipe is an overflow pipe capable of controlling the amount of sewage stored inside the tank.

[0014] Furthermore, it also includes a motor installed on the water collection tank, a transmission wheel installed on the output end of the motor, and a transmission ring installed on the vertical pipe. The motor drives the vertical pipe to rotate through the transmission wheel and the transmission ring.

[0015] The advantages of this invention are:

[0016] By employing a method of first concentrating and then extruding to treat scum, the treatment efficiency and effect can be greatly improved. During extrusion, the scum will not be unable to withstand force due to its excessive water content and high fluidity, thus improving the extrusion effect. Furthermore, since impurities are always in a state of movement within the barrel, they will not remain on the surface of the filter cartridge and cause blockage. This allows the equipment to maintain stable operation and effectively treat scum. Attached Figure Description

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0026] like Figures 1 to 4 As shown, the present invention provides a flotation and scum treatment device for wastewater from a garment factory, comprising a barrel 1 and a rotating body 2, wherein the rotating body 2 is vertically located inside the barrel 1 and can rotate to treat impurities inside the barrel 1.

[0027] The barrel 1 is composed of a lower cone and an upper column, and the column is connected to a discharge channel 3 for discharging impurities after pressure filtration;

[0028] The rotating body 2 consists of a lower vertical tube 4 and an upper filter cylinder 5. A centrifugal plate 6 is provided on the vertical tube 4, and a plurality of spiral plates 7 for pushing impurities are provided on the filter cylinder 5. The top of the spiral plate 7 is provided with a pressure ring 8 that can slide on the filter cylinder 5 and squeeze the impurities conveyed by the spiral plate 7.

[0029] In detail, the vertical pipe 4 corresponds to the conical part of the barrel 1, and the filter cylinder 5 corresponds to the cylindrical part of the barrel 1. When treating sewage scum, the scum is introduced into the conical part of the barrel 1 and a specified amount of scum is stored in the conical part. The rotating body 2 is rotated, which drives the vertical pipe 4, filter cylinder 5, centrifugal plate 6, spiral plate 7, and pressure ring 8 to rotate synchronously. The centrifugal plate 6 agitates the scum. Since the scum contains a large amount of water, and the specific gravity of water is greater than that of scum, the water will stay near the inner wall of the cone, while impurities will be pushed towards the vicinity of the vertical pipe 4. As scum is continuously introduced, the amount of sewage in the conical part increases, and impurities float on the sewage, thereby achieving the concentration of impurities. The shape of the conical part allows the sewage to move towards the bottom of the conical part, thereby lifting the impurities and causing them to rise towards the cylindrical part. When the impurities move to the cylindrical part... Inside, the rotating spiral plate 7 scoops up impurities and conveys them upwards. The impurities move to the position of the pressure ring 8, where the pressure ring 8 exerts downward pressure on the impurities, thus squeezing and dewatering them. As the amount of impurities gradually increases, the pressure ring 8 gradually moves upwards. When the impurities reach the position of the discharge channel 3, they can be discharged through the discharge channel 3. This achieves the dual treatment effect of scum concentration and squeezing dewatering. Since the impurities are always in a moving state inside the barrel 1, they will not always remain on the surface of the filter cylinder 5 and cause blockage. This allows the equipment to maintain stable operation and treat scum. After concentration, the water content in the scum can be greatly reduced, facilitating subsequent normal squeezing and preventing the scum from being unable to withstand force due to its strong fluidity when the water content is too high, thereby improving the scum treatment effect.

[0030] Furthermore, the filter cartridge 5 is composed of a lower first conical surface, a middle second conical surface, and an upper cylindrical surface, with the spiral plate 7 located on the second conical surface and the pressure ring 8 located on the cylindrical surface;

[0031] A vertical plate 9 is provided at the upper end of each spiral plate 7. The vertical plate 9 extends to the cylindrical surface and slides through the pressure ring 8 to guide the pressure ring 8.

[0032] In detail, the first conical surface can gather impurities as they move upwards, and the second conical surface can reduce the space for impurities to move when the spiral plate 7 pushes them, thereby further improving the squeezing effect on the impurities. The vertical plate 9 can guide the pressure ring 8, so that the pressure ring 8 can move smoothly on the cylindrical surface, and the filter cylinder 5 can drive the pressure ring 8 to rotate through the vertical plate 9, so that the pressure ring 8 can rotate and discharge the impurities at its bottom into the impurity discharge channel 3.

[0033] Furthermore, the filter cartridge 5 has a mounting plate 10 on its cylindrical surface. The mounting plate 10 is connected to the pressure ring 8 by a spring 11. The spring 11 has a guide post 12 for guiding the spring 11. The guide post 12 slides through the mounting plate 10.

[0034] In detail, the spring 11 provides elastic thrust to the pressure ring 8, thereby facilitating the pressure ring 8 to squeeze impurities. The mounting plate 10 and the guide post 12 support and guide the spring 11.

[0035] Furthermore, the centrifugal plate 6 is arranged along the inclined direction of the cone of the barrel 1, and a specified distance is left between the centrifugal plate 6 and the inner wall of the cone. The centrifugal plate 6 is connected to the vertical tube 4 by a connecting rod 13.

[0036] In detail, the centrifuge plate 6 is close to the inner wall of the cone. When the vertical tube 4 rotates, the centrifuge plate 6 can agitate the sewage at a position away from the vertical tube 4. This allows the centrifuge plate 6 to act only on the sewage and not directly on the impurities, so that the impurities can be better separated from the sewage. The space between the centrifuge plate 6 and the vertical tube 4 is used to provide space for the separation of impurities and sewage, and to prevent the centrifuge plate 6 from breaking up the impurities and causing them to spread randomly.

[0037] Furthermore, a water collection tank 14 is provided at the bottom of the barrel 1, and the bottom of the vertical pipe 4 passes through the barrel 1 and is inserted into the water collection tank 14, thereby connecting the filter cartridge 5 to the water collection tank 14 through the vertical pipe 4. The water collection tank 14 is connected to the conical part of the barrel 1 through the water guide pipe 15. A drain pipe 16 is provided at the bottom of the water collection tank 14, a feed pipe 17 is provided at the bottom of the barrel 1, and a vent pipe 23 is provided at the top of the filter cartridge 5.

[0038] In detail, scum can be introduced into the barrel 1 through the feed pipe 17, and the water separated by the conical part of the barrel 1 can be discharged into the water collection tank 14 through the water guide pipe 15. The sewage collected in the filter cylinder 5 can be discharged into the water collection tank 14 through the vertical pipe 4. The sewage in the water collection tank 14 is discharged through the drain pipe 16, thereby realizing the sewage transportation work. The vent pipe 23 at the top of the filter cylinder 5 is to stabilize the air pressure inside the filter cylinder 5.

[0039] Furthermore, a rotating ring 18 is provided at the end of the vertical pipe 4 inside the water collection tank 14, and multiple deflectors 19 are inclinedly provided on the rotating ring 18, with the multiple deflectors 19 arranged in a ring.

[0040] In detail, the vertical pipe 4 will drive the rotating ring 18 and the deflector 19 to rotate synchronously. The deflector 19 will push the sewage in the water collection tank 14 that is close to the vertical pipe 4 to a position away from the vertical pipe 4, thereby reducing the water pressure at the connection between the vertical pipe 4 and the water collection tank 14 and improving the sealing performance of the vertical pipe 4 when it rotates on the water collection tank 14.

[0041] Furthermore, the drain pipe 16 is an overflow pipe capable of controlling the amount of sewage stored in the tank 1.

[0042] In detail, by using an overflow pipe, the wastewater in the conical part of the tank 1 can be kept at a specified level, so as to facilitate better concentration of scum.

[0043] Furthermore, it also includes a motor 20 installed on the water collection tank 14, a transmission wheel 21 installed on the output end of the motor 20, and a transmission ring 22 installed on the vertical pipe 4. The motor 20 drives the vertical pipe 4 to rotate through the transmission wheel 21 and the transmission ring 22.

[0044] In detail, the motor 20, the transmission wheel 21, and the transmission ring 22 provide power for the rotation of the rotating body 2.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
