Description

Technical Field

[0001] This utility model relates to the field of waste metal and waste liquid treatment technology, and in particular to a collection and cleaning device. Background Technology

[0002] During the recycling, dismantling, crushing, cleaning, and machining of scrap metal, a large amount of complex waste liquid is generated. This waste liquid is typically mixed with solid particles such as metal shavings and silt, as well as various oily substances such as lubricating oil, cutting fluid, and cleaning agents, forming a complex three-phase mixture of solid, liquid, and oil. Direct discharge without treatment will severely pollute soil and water bodies. Therefore, the efficient collection and deep cleaning of waste metal waste liquid to achieve resource recovery and environmental protection is an inevitable requirement for the green development of the metal recycling industry.

[0003] A search revealed that patent CN223221122U discloses a metal waste liquid collection and cleaning device, which can sequentially filter and collect particulate matter in metal waste liquid from large to small through large-pore filter plates, small-pore filter plates, and polymer microporous filter screen plates.

[0004] However, the aforementioned device has the following drawbacks: it focuses solely on solid-liquid separation, completely ignoring the most harmful, most valuable for recycling, and most difficult-to-treat component of waste metal wastewater—oil. The lack of integrated oil-water separation structures (such as oil separation, demulsification, and coalescence) results in the outlet still being oily wastewater, failing to meet environmental emission or reuse requirements, significantly diminishing the device's value. Furthermore, when faced with wastewater containing oil and viscous impurities, the first layer of the multi-layer flat plate filter quickly becomes caked with oil and sludge, forming a dense filter cake. The backflushing gas below has little effect on this paste-like substance. Therefore, further improvements are needed. To this end, we propose a collection and cleaning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a collection and cleaning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a collection and cleaning device, including a base frame, a box body fixed on the upper surface of the base frame, and a circular hole opened in the top wall of the box body, and an annular plate rotatably connected inside the circular hole via a bearing, a detachable solid-liquid separation component fixed inside the annular plate, and the solid-liquid separation component including a mesh cylinder penetrating inside the annular plate, a horizontal flap fixed on the top of the annular plate, a motor for driving the flap to rotate fixed on the upper surface of the box body, an aeration component fixedly installed inside the base frame and at the bottom of the box body, and a drain pipe and an oil drain pipe fixed at the bottom end of the side wall of the box body, with the drain pipe located below the oil drain pipe.

[0007] Furthermore, a top plate is fixed to the top of the mesh cylinder, the top plate is located on the upper surface of the flip plate, and an installation hole is opened on the side of the top plate. A screw is fixed to the upper surface of the flip plate, the screw passes through the installation hole and the top surface of the screw is threaded with an internal thread cap, and handles are fixed on both sides of the top of the mesh cylinder.

[0008] Furthermore, a support ring is fixed to the top of the inner wall of the mesh cylinder, and a top cover is rotatably connected to the top of the mesh cylinder via a hinge. The side of the top cover away from the hinge is magnetically attracted and fixed to the support ring.

[0009] Furthermore, the outer wall of the flap is fixed with several protruding teeth, and the output end of the motor is fixed with a gear, which meshes with the protruding teeth.

[0010] Furthermore, the aeration assembly includes an air pump fixed inside the base frame, an air supply pipe fixedly connected to the air outlet of the air pump, the other end of the air supply pipe extending into the interior of the housing, and several nozzles fixed at one end of the air supply pipe inside the housing.

[0011] Furthermore, several inclined plates are fixed inside the housing and above the nozzle.

[0012] Furthermore, valves are fixedly installed in the middle of both the drain pipe and the oil drain pipe.

[0013] The beneficial effects of this utility model are:

[0014] In use, this invention first drives the solid-liquid separation component to rotate at high speed via a motor, throwing the water and oil in the waste metal to the bottom of the tank. Then, the aeration component aerates the oil-water mixture, generating tiny bubbles. These bubbles forcefully impact the oil droplets, achieving air flotation and demulsification, causing the emulsified oil to destabilize, adhere to the bubbles, and float to the surface. The floating oil-air complex and free oil further coalesce on the inclined plate surface, forming large oil droplets, which then accelerate to float to the oil collection tank, thus achieving oil-water separation. This device not only achieves efficient solid-liquid separation but also oil-water separation, greatly improving the waste liquid treatment effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a collection and cleaning device is disclosed, comprising a base frame 1, a box 2 fixed on the upper surface of the base frame 1, and a circular hole on the top wall of the box 2, wherein an annular plate 3 is rotatably connected to the inside of the circular hole via a bearing, a detachable solid-liquid separation component 4 is fixed inside the annular plate 3, and the solid-liquid separation component 4 includes a mesh cylinder 41 penetrating the inside of the annular plate 3, a horizontal flap 5 is fixed on the top of the annular plate 3, a motor 8 for driving the flap 5 to rotate is fixed on the upper surface of the box 2, an aeration component 9 is fixedly installed inside the base frame 1 and at the bottom of the box 2, and a drain pipe 11 and an oil drain pipe 12 are fixed at the bottom end of the side wall of the box 2, with the drain pipe 11 located below the oil drain pipe 12.

[0023] A top plate 42 is fixed at the top of the mesh cylinder 41. The top plate 42 is located on the upper surface of the flip plate 5, and an installation hole 43 is opened on the side of the top plate 42. A screw 6 is fixed on the upper surface of the flip plate 5. The screw 6 passes through the installation hole 43 and has an internal thread cap 7 threaded on its top surface. Handles 44 are fixed on both sides of the top of the mesh cylinder 41.

[0024] The internal thread cap 7 is screwed onto the surface of the screw rod 6, and the internal thread cap 7 is used to press and fix the top plate 42, so that the annular plate 3 and the mesh cylinder 41 are connected into an integral structure. When it is necessary to clean the solid waste metal inside the mesh cylinder 41, the internal thread cap 7 is unscrewed, and the top plate 42 is lifted by the handle 44, so that the mesh cylinder 41 can be taken out from the inside of the annular plate 3, making it convenient to pour out the waste metal inside the mesh cylinder 41.

[0025] A support ring 45 is fixed to the top of the inner wall of the mesh cylinder 41. A top cover 46 is rotatably connected to the top of the mesh cylinder 41 via a hinge. The side of the top cover 46 away from the hinge is magnetically attracted and fixed to the support ring 45.

[0026] The support ring 45 can support the top cover 46. Rotating the top cover 46 allows waste metal and oil-water mixture to be poured into the mesh cylinder 41.

[0027] Several protruding teeth 51 are fixed on the outer wall of the flap 5, and a gear 81 is fixed on the output end of the motor 8. The gear 81 meshes with the protruding teeth 51.

[0028] Under the meshing transmission of gear 81 and convex tooth 51, the starting motor 8 can drive the flap 5 to rotate, thereby driving the top plate 42 and the mesh cylinder 41 to rotate through the flap 5. Under the action of centrifugal force, the oil-water mixture is thrown out and enters the bottom of the box 2.

[0029] The aeration assembly 9 includes an air pump 91 fixed inside the base frame 1. An air supply pipe 92 is fixedly connected to the air outlet of the air pump 91. The other end of the air supply pipe 92 extends into the interior of the housing 2. Several nozzles 93 are fixed to one end of the air supply pipe 92 inside the housing 2.

[0030] Several inclined plates 10 are fixed inside the housing 2 and above the nozzle 93.

[0031] After the air pump 91 is started, air is delivered through the air pipe 92 and finally discharged from the nozzle 93, forming tiny bubbles. These bubbles forcefully impact the oil droplets, achieving air flotation and demulsification, causing the emulsified oil to destabilize, adhere to the bubbles and float. The floating oil-air complex and free oil further coalesce on the surface of the inclined plate 10, forming large oil droplets, which accelerate to float to the oil collection tank, thereby achieving oil-water separation.

[0032] Valves are fixedly installed in the middle of both drain pipe 11 and oil drain pipe 12.

[0033] After the oil-water separation is completed, first open the valve on the drain pipe 11 to drain the lower layer of water. When the lower layer of oil is lower than the oil drain pipe 12, close the valve on the drain pipe 11 and open the valve on the oil drain pipe 12 to drain the upper layer of oil. After the oil is drained, open the valve on the drain pipe 11 again to drain the remaining water.

[0034] Working principle: First, open the top cover 46 and pour the oily waste metal material to be processed into the screen cylinder 41 of the solid-liquid separation component 4, then close the top cover 46. Start the motor 8, which, through the gear 81 at its output end, meshes with the convex teeth 51 on the outer side of the flap 5, driving the flap 5 and the annular plate 3 fixed on it, along with the screen cylinder 41, to rotate at high speed. Under the action of strong centrifugal force, the oil and water mixture adhering to the surface of the solid waste metal is thrown out of the screen cylinder 41 and enters the bottom of the tank 2, achieving preliminary solid-liquid separation.

[0035] After solid-liquid separation is completed, the air pump 91 of the aeration component 9 is activated. Air is delivered through the air supply pipe 92 to multiple nozzles 93 at the bottom of the tank 2, forming a large number of tiny bubbles that escape upwards. During their ascent, these bubbles powerfully impact and agitate the oil-water mixture at the bottom of the tank 2, achieving air flotation and demulsification, causing the fine emulsified oil droplets to destabilize and adhere to the bubble surface. The bubbles carry the oil droplets as they continue to rise. When they pass through multiple inclined plates 10 fixedly installed in the middle of the tank 2, the oil-air complex and free oil collide and coalesce on the surface of the inclined plates 10, forming larger oil droplet clusters, thereby accelerating the upward movement.

[0036] Finally, the coalesced large oil droplets rise to the top of the tank 2, forming a continuous oil layer. After processing, first open the valve on the drain pipe 11 located at the lower side wall of the tank 2 to drain the clear water separated from the lower layer. When the oil-water interface drops below the opening of the oil drain pipe 12, close the valve on the drain pipe 11 and open the valve on the oil drain pipe 12 located above the drain pipe 11 to drain the waste oil collected in the upper layer. After draining the oil, the valve on the drain pipe 11 can be opened again to empty the remaining liquid in the tank. The solid waste metal trapped in the mesh cylinder 41 can be removed from the tank by unscrewing the internal thread cap 7 and using the handle 44 after processing for cleaning.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
