Description

Technical Field

[0001] This application relates to the field of steel processing, and more specifically, to a cleaning device and waste steel processing equipment. Background Technology

[0002] During the use of steel, some unused scraps are often generated. Due to limitations in size and shape, these scraps are often difficult to reuse. At the same time, some scrap steel has no value for use, so it is necessary to recycle these steels.

[0003] For example, Chinese utility model patent application number CN201921948896.0 discloses a waste steel recycling and processing device, which introduces external water into the cleaning tank through the water inlet pipe, and uses the stirring structure in the cleaning tank to agitate the crushed steel, thereby cleaning it. After draining, the external hot air is introduced into the cleaning tank by the fan and the electric heating block in the drying chamber to dry the steel, thereby improving the cleaning effect.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] 1. The above solution only designs water inlet and outlet pipes to draw water into the cleaning tank and drain water. It lacks a water circulation and filtration structure, making it difficult to reuse the discharged water, which indirectly increases the cost of cleaning scrap steel.

[0006] 2. In the above scheme, when the scrap steel is dried in the washing tank, the scrap steel still needs to be manually removed from the washing tank because no auxiliary unloading structure is designed, which increases the labor cost of the washing device. Utility Model Content

[0007] To overcome the above deficiencies, this application provides a cleaning device and a waste steel processing equipment. Through the design of water circulation components and discharge components, this application can not only recycle water resources, but also quickly unload the dried waste steel, thereby indirectly reducing the operating cost of the cleaning device.

[0008] This application provides a cleaning device, including a cleaning tank and a feeding hopper located on top of it, as well as a water circulation component and a discharge component:

[0009] The water circulation component includes a water tank whose top is connected to the bottom of the cleaning tank, an inlet pipe connecting the bottom of the water tank to the top of the cleaning tank, a pump body on the inlet pipe, and a filter in the middle of the water tank.

[0010] The bottom of the cleaning tank of the discharge component is open to the outside. The discharge component includes a sealing plate that is hinged to the bottom of the cleaning tank. An electric telescopic rod is provided on the outside of the cleaning tank. The movable end of the electric telescopic rod is connected to the sealing plate.

[0011] Preferably, a drain pipe is connected between the bottom of the cleaning tank and the top of the water tank, and a gate valve is installed on the drain pipe.

[0012] Preferably, the filter element includes a filter screen and a fixing plate connected to its outer end. A pull-out opening is provided on the side wall of the water tank. The filter screen moves into the water tank through the pull-out opening. A pair of pads for supporting the frame of the filter screen are fixed on the inner wall of the water tank opposite to the pull-out opening. The fixing plate is provided with locking bolts for movably fixing the filter screen to the outer wall of the water tank.

[0013] Preferably, a sealing rubber gasket is adhered to the periphery of the upper surface of the sealing plate and is movably attached to the bottom of the cleaning tank.

[0014] Preferably, the bottom of the cleaning tank is provided with a stirring component;

[0015] The stirring component includes a servo motor A mounted on the outer wall of the cleaning tank. The output end of the servo motor A is provided with a ball screw pair. The outer wall of the ball screw pair is provided with a screw nut. The outer wall of the screw nut is connected to a connecting block. The bottom of the connecting block is provided with an inclined plate. The bottom of the inclined plate is connected with stirring rods at equal intervals. A sliding rod is fixed on the inclined plate. A slide rail adapted to the sliding rod is opened laterally at the top of the cleaning tank.

[0016] This application also provides a waste steel processing equipment, including the above-mentioned cleaning device, and the feeding hopper is provided with a crushing component;

[0017] The crushing component includes a servo motor B installed on the top of the washing tank. The output end of the servo motor B is connected to a gear A. The inner cavity of the feeding hopper is laterally rotatably connected to two meshing crushing rollers. Both crushing rollers extend to the outside of the feeding hopper and are connected to meshing gears B. Gear A meshes with one of the gears B.

[0018] The waste steel processing equipment also includes a drying component;

[0019] The drying component includes a U-shaped air duct surrounding the upper part of the outer wall of the cleaning chamber. Air inlet pipes are equidistantly connected to the U-shaped air duct and are connected to the interior of the cleaning chamber. A main air duct is also connected to the U-shaped air duct. The bottom end of the main air duct is connected to an exhaust fan fixed to the outer wall of the cleaning chamber. The air inlet end of the exhaust fan is connected to a drying chamber, and an electric heating plate is installed in the drying chamber.

[0020] Preferably, the dryer has air inlets equidistantly spaced on its outer side.

[0021] Beneficial effects: This application provides a cleaning device and scrap steel processing equipment. Scrap steel is fed into the cleaning tank through a feeding hopper. The pump body is turned on to introduce clean water from the water tank into the cleaning tank through the inlet pipe, assisting in the cleaning of the scrap steel. After cleaning, the electric telescopic rod is activated to control the sealing plate to rotate around its hinge point with the bottom of the cleaning tank, so that the sealing plate no longer seals the bottom of the cleaning tank. At this time, the cleaned scrap steel in the cleaning tank will fall from its open bottom into the external receiving frame by its own weight. Thus, this application can not only recycle water resources, but also quickly unload the dried scrap steel, indirectly reducing the operating cost of the cleaning device. Attached Figure Description

Detailed Implementation

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] Please see Figures 1-4 , Figure 7 This application provides a cleaning device, including a cleaning tank 1 and a feeding hopper 2 disposed on top thereon, and also includes a water circulation component 6 and a discharge component 5:

[0037] The water circulation component 6 includes a water tank 63 whose top is connected to the bottom of the cleaning tank 1. A water inlet pipe 65 is connected between the bottom of the water tank 63 and the top of the cleaning tank 1. A pump body 66 is provided on the water inlet pipe 65, and a filter element 64 is provided in the middle of the water tank 63.

[0038] The bottom of the discharge component 5 and the cleaning box 1 are open to the outside. The discharge component 5 includes a sealing plate 52 that is hinged to the bottom of the cleaning box 1. An electric telescopic rod 51 is provided on the outside of the cleaning box 1. The movable end of the electric telescopic rod 51 is connected to the sealing plate 52.

[0039] In this embodiment, scrap steel is fed into the cleaning tank 1 through the feeding hopper 2. The pump 66 is activated to introduce clean water from the water tank 63 into the cleaning tank 1 through the inlet pipe 65, assisting in the cleaning of the scrap steel. After cleaning, the electric telescopic rod 51 is activated to control the sealing plate 52 to rotate around its hinge point with the bottom of the cleaning tank 1, so that the sealing plate 52 no longer seals the bottom of the cleaning tank 1. At this time, the cleaned scrap steel in the cleaning tank 1 will fall from its open bottom into the external receiving frame by its own weight. This allows the present application not only to recycle water resources but also to quickly unload the dried scrap steel, indirectly reducing the operating cost of the cleaning device.

[0040] It should also be noted that L-shaped support legs are fixed at the four outer corners of the bottom of the cleaning tank 1, and the external receiving frame for receiving materials can be placed between the four L-shaped support legs.

[0041] Please see Figure 7 A drain pipe 61 connects the bottom of the cleaning tank 1 and the top of the water tank 63, and a gate valve 62 is installed on the drain pipe 61. Specifically, the gate valve 62 can be used to control the drain pipe 61 to discharge the water from the cleaning tank 1 after cleaning the scrap steel.

[0042] Please see Figures 7-9 The filter element 64 includes a filter screen 641 and a fixing plate 642 connected to its outer end. A pull-out opening 631 is provided on the side wall of the water tank 63. The filter screen 641 moves into the water tank 63 through the pull-out opening 631. Pairs of pads 67 for supporting the frame of the filter screen 641 are fixed on the inner wall of the water tank 63 opposite to the pull-out opening 631. The fixing plate 642 is provided with locking bolts 643 for movably fixing it to the outer wall of the water tank 63. Specifically, wastewater discharged from the drain pipe 61 enters the water tank 63 from the top and can be reused after being treated by the filter screen 641. When the filter screen 641 is severely clogged and needs replacement, the locking bolts 643 are loosened, and the fixing plate 642 is pulled out from the pull-out opening 631 for cleaning or replacement.

[0043] Please see Figure 4 A sealing rubber gasket 53 is attached to the periphery of the upper surface of the sealing plate 52 and is movable and tightly attached to the bottom of the cleaning tank 1. Specifically, the sealing function of the sealing rubber gasket 53 can reduce the probability of water in the cleaning tank 1 overflowing from the gap between it and the sealing plate 52.

[0044] Please see Figures 3-5 The bottom of the cleaning tank 1 is equipped with a stirring component 4;

[0045] The stirring component 4 includes a servo motor A41 mounted on the outer wall of the cleaning tank 1. A ball screw assembly 42 is located at the output end of the servo motor A41. A screw nut 43 is located on the outer wall of the ball screw assembly 42. A connecting block 44 is connected to the outer wall of the screw nut 43. An inclined plate 45 is located at the bottom of the connecting block 44. Stirring rods 47 are equidistantly connected to the bottom of the inclined plate 45. A sliding rod 46 is fixed on the inclined plate 45. A slide rail 11, adapted to the sliding rod 46, is horizontally opened at the top of the cleaning tank 1. Specifically, starting the servo motor A41 controls the ball screw assembly 42 to rotate, causing the screw nut 43 to reciprocate left and right along the ball screw assembly 42 with the assistance of the sliding rod 46 and the slide rail 11. This drives the stirring rod 47 at the bottom of the inclined plate 45 to stir the scrap steel in the cleaning tank 1, effectively removing the substances adhering to the steel blocks and facilitating the recycling of the steel.

[0046] Please see Figure 1 , Figure 2 and Figure 6 This application also provides a waste steel processing equipment, including the above-mentioned cleaning device, and the feeding hopper 2 is provided with a crushing component 3;

[0047] The crushing component 3 includes a servo motor B31 mounted on the top of the washing tank 1. The output end of the servo motor B31 is connected to a gear A32. Two meshing crushing rollers 33 are laterally rotatably connected to the inner cavity of the feeding hopper 2. Both crushing rollers 33 extend outside the feeding hopper 2 and are each connected to a meshing gear B34. Gear A32 meshes with one of the gears B34. Specifically, starting the servo motor B31 controls the rotation of gear A32, indirectly driving the meshing gear B34 to rotate. This causes the two crushing rollers 33 to rotate in opposite directions, allowing the blades on the crushing rollers 33 to crush the scrap steel entering the feeding hopper 2, facilitating subsequent steel processing and improving steel processing efficiency.

[0048] Please see Figures 1-3 , Figure 10 and Figure 11 The waste steel processing equipment also includes a drying component 7;

[0049] The drying component 7 includes a U-shaped air duct 71 surrounding the upper part of the outer wall of the cleaning chamber 1. Air inlet pipes 72 are equidistantly connected to the U-shaped air duct 71 and extend into the interior of the cleaning chamber 1. A main air duct 73 is also connected to the U-shaped air duct 71. An exhaust fan 74, fixed to the outer wall of the cleaning chamber 1, is connected to the bottom end of the main air duct 73. The air inlet of the exhaust fan 74 is connected to a drying chamber 75, where an electric heating plate 76 is installed. Specifically, the electric heating plate 76 and the exhaust fan 74 are activated sequentially. The electric heating plate 76 heats the external air introduced into the main air duct 73 by the exhaust fan 74. The heated air then passes through the U-shaped air duct 71 and the air inlet pipes 72 into the cleaning chamber 1. Compared to the single air inlet structure in the above-mentioned scheme, this application can introduce hot air into the cleaning chamber 1 from more directions, resulting in faster air delivery efficiency and accelerating the temperature rise process inside the cleaning chamber 1, which is more conducive to the drying of scrap steel.

[0050] The drying chamber 75 has air inlets at equal intervals on its outer side. Outside air can enter the drying chamber 75 through the air inlets for heating treatment.

[0051] When this application is used:

[0052] Scrap steel is fed into the washing tank 1 through the feeding hopper 2. Activating the servo motor B31 controls the rotation of gear A32, indirectly driving the meshing gear B34 to rotate. This causes the two crushing rollers 33 to rotate in opposite directions, allowing the blades on the crushing rollers 33 to crush the scrap steel entering the feeding hopper 2, facilitating subsequent steel processing and improving processing efficiency. The pump body 66 is activated to introduce clean water from the water tank 63 into the washing tank 1 through the inlet pipe 65. Activating the servo motor A41 controls the rotation of the ball screw assembly 42, causing the screw nut 43 to move back and forth along the ball screw assembly 42 with the assistance of the slide rod 46 and the slide rail 11. This drives the stirring rod 47 at the bottom of the inclined plate 45 to agitate the scrap steel in the washing tank 1, effectively removing adhering substances from the steel blocks and facilitating steel recycling. The wastewater after cleaning is discharged from the drain pipe 61 and can be reused after being treated by the filter screen 641. At this time, the electric heating plate 76 and the exhaust fan 74 are activated in sequence. The electric heating plate 76 heats the outside air introduced into the main air duct 73 by the exhaust fan 74. The heated air then enters the cleaning chamber 1 through the U-shaped air duct 71 and the air inlet pipe 72 in sequence, allowing hot air to be introduced into the cleaning chamber 1 from more directions, thereby accelerating the temperature rise process inside the cleaning chamber 1 and making it more conducive to the drying of scrap steel. After drying, the electric telescopic rod 51 is activated to control the sealing plate 52 to rotate around its hinge point with the bottom of the cleaning chamber 1, so that the sealing plate 52 no longer seals the bottom of the cleaning chamber 1. At this time, the cleaned scrap steel in the cleaning chamber 1 will fall into the external receiving frame from its open bottom by its own weight.

[0053] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
