During processing, metal debris tends to splash around and may be scattered on the surface of the machine, aisles, and other places. Traditional methods of collecting metal debris are usually limited to processing machines. For metal debris in other locations such as aisles, direct sweeping is often adopted, which is not convenient for reasonable classification and collection of debris, so as to carry out recycling metallurgy, or process it into other metal parts and civilian appliances to achieve effective reuse of resources.

[0004] In view of this, the present invention provides a metal debris collecting and cleaning device. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the metal debris collection and cleaning device, the debris is transported to the inside of the collection box by the conveying component, and the metal debris entering the collection box is crushed by the crushing component, so that larger fragments are broken into small pieces, which facilitates the block debris to be stacked more closely together, reduces the required storage space, improves space utilization, and is easier to load and unload and carry during transportation.

[0017] 2. In the metal debris collection and cleaning device, the debris entering the collection box is classified and collected by the sub-screening component. The powder debris is blown to the particle board by the wind of the sub-screening component, while the block debris is directly filtered between the collection box and the two particle boards;

[0018] And when the wind blows the screening component, it drives the blade of the crushing component to flip, so that the crushing component can not only crush the debris, but also pick up the large debris that has not been filtered out for secondary crushing, so as to avoid blockage of the screening component.

[0036] Example

[0037] See also Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide a metal debris collection and cleaning device, including a base 1, a chassis 11 and a collection box 12 are fixedly connected to the top of the base 1, a support plate 120 is fixedly connected to the inside of the collection box 12 near the top, a particle board 122 is fixedly connected to the end of the collection box 12, particle boards 121 are fixedly connected to both sides of the collection box 12, and a bracket 2 is fixedly connected to the top of the collection box 12 near the particle board 121;

[0038] A screening assembly 14 is fixedly connected between the collecting box 12 and the inside of the chassis 11, a crushing assembly 13 is movably connected between the support plate 120 and the inside of the collecting box 12, and a conveying assembly 15 is movably connected between the bracket 2 and the inside of the chassis 11;

[0039] The crushing assembly 13 is used to crush larger metal debris, and the screening assembly 14 is used to classify and collect the powder and fragments in the metal debris, and at the same time drive the crushing assembly 13 to flip and pick up the fragments that are not completely crushed for secondary crushing, and increase the collision frequency between the debris and the crushing assembly 13;

[0040] The improvement of this embodiment is that the debris is transported to the inside of the collection box 12 through the conveying component 15, and the metal debris entering the collection box 12 is crushed by the crushing component 13, so that larger fragments are broken into small pieces, which facilitates the block debris to be stacked more tightly together, reduces the required storage space, improves space utilization, and is easier to load and unload and carry during transportation.

[0041] Through the wind blowing of the screening component 14, the debris entering the collecting box 12 is classified and collected, and the powdered debris is blown to the particle board 122, while the block debris is directly filtered between the collecting box 12 and the two particle boards 121; and while the wind blowing of the screening component 14, the blade 131 of the crushing component 13 is driven to flip, so that the crushing component 13 can not only crush the debris, but also pick up the large pieces of debris that have not been filtered out for secondary crushing, so as to avoid the clogging of the screening component 14. At the same time, the blown debris collides between the crushing component 13 and the collecting box 12, making it easier to be acted on by the crushing tool, thereby improving the uniformity and efficiency of the crushing.

[0042] First, the specific structure of the crushing assembly 13 is disclosed. The crushing assembly 13 includes a rotating rod 130, which is movably connected to the inside of the support plate 120. Two belt pulleys 132 are movably connected to the inside of the support plate 120. A belt 133 is movably connected between the two belt pulleys 132, and one of the belt pulleys 132 is fixedly connected to the top of the rotating rod 130; the rotating rod 130 passes through the outer wall of the support plate 120 and is fixedly connected to two shaft rods 134, and the outer wall of the shaft rod 134 is movably connected to a blade 131;

[0043] See also Figure 2 , Figure 3 and Figure 6As shown, one of the belt pulleys 132 is driven to rotate by the motor output shaft, and under the action of this driving force, the belt 133 rotates accordingly and drives the other belt pulley 132 to rotate together; then, the belt pulley 132 further drives the rotating rod 130 to rotate. When the rotating rod 130 rotates, it drives the shaft 134 and the blade 131 to rotate with the rotating rod 130 as the center, so that the blade 131 crushes the metal debris entering the collection box 12; the original large debris is broken into multiple small pieces, so that the block debris can be stacked more tightly together. This state not only reduces the required storage space and greatly improves the space utilization rate, but also during the transportation process, these small pieces of debris are easier to load and unload and carry, which brings great convenience to the subsequent processing and transportation of the metal debris.

[0044] Next, the specific structure of the sub-screening assembly 14 is disclosed. The sub-screening assembly 14 includes an axial flow fan 140, which is fixedly connected between the end of the collection box 12 and the inside of the chassis 11, and the end of the axial flow fan 140 is fixedly connected to an electric heating network 143, and the other end of the collection box 12 is fixedly connected to a filter 142, and the inside of the collection box 12 is fixedly connected to a sieve plate 141 between the electric heating network 143 and the filter 142;

[0045] See also Figure 2 , Figure 3 and Figure 5 As shown, the crushed metal debris is finely screened by the screen plate 141, wherein small pieces of metal debris can pass through the screen plate 141 and enter the area between the collecting box 12 and the bottom of the screen plate 141 and the two particle plates 121; at this time, the axial flow fan 140 starts to rotate and blow air, as shown in FIG. Figure 2 In the blowing direction indicated by the hollow arrow, under the continuous action of wind force, the metal debris entering the collection box 12 will be blown toward the particle board 122 along with the gas flow; at this time, the filter 142 intercepts the block debris in the metal debris blowing toward the particle board 122, while the powder particles in the metal debris are blown toward the particle board 122 along with the air flow, thereby being separated from the block debris in the metal debris; after the metal debris is classified and collected in this way, more efficient recycling treatment can be adopted for the powder debris and the block debris respectively;

[0046] Moreover, when the axial flow fan 140 blows, since the blade 131 is located at a position slightly above the wind force of the axial flow fan 140, the wind force felt by the blade 131 shows a trend of gradually weakening from bottom to top; this wind force distribution can exert a clockwise rotation force on the blade 131, prompting the blade 131 to turn over on the outer wall of the shaft 134; in this way, when the blade 131 rotates to perform the crushing work, the larger fragments blocked on the top of the screen plate 141 can be lifted upward, and then the blocked fragments can be crushed for the second time under the continuous rotation of the blade 131, which greatly improves the crushing accuracy;

[0047] At the same time, a timer is installed in the power control circuit of the axial flow fan 140 motor, and the output end of the timer is connected to the power supply circuit of the axial flow fan 140 motor (live wire L and neutral wire N), which can control the on and off of the live wire, set the power-on time T1 and the power-off time T2, and the timer clock circuit counts. When T1 is reached, the control circuit triggers the output end to close, and the motor is powered on to drive the fan to blow air; after the power is turned on, the clock continues to count, and at this time T2, the output end is disconnected, the motor is powered off, and the fan stops. This cycle realizes intermittent fan blowing; through the intermittent blowing state of the axial flow fan 140, it is convenient for metal debris to cycle back and forth between the crushing and separation states, and avoids the continuous output of wind power affecting the screening of large and small fragments;

[0048] The working principle of the timer is known to those skilled in the art. The timer is a device that can perform on-off control according to a preset time interval. It is usually composed of a clock circuit, a control circuit and an output circuit. The clock circuit generates an accurate time reference, and the control circuit determines the on-off state of the output circuit according to a preset time parameter.

[0049] When the electric heating network 143 is powered on, heat is generated. At this time, when the axial flow fan 140 blows air through the electric heating network 143, the air is heated and blows out hot air to dry the wet metal scraps inside the collection box 12, and can preheat the metal scraps to volatilize or melt some low melting point impurities, which is convenient for resource recovery and reuse;

[0050] The working principle of the axial flow fan 140 is known to those skilled in the art. When the motor is powered on, it drives the impeller to rotate. The impeller is usually propeller-shaped and has multiple blades. When the impeller rotates, the blades generate axial thrust on the air, causing the air to flow along the axial direction of the impeller, just like a propeller pushing a ship forward. Under the action of the axial flow fan 140, the air is sucked in from one end of the fan, and after being accelerated and pushed by the impeller, it is blown out from the other end of the fan at a certain speed and pressure.

[0051] The working principle of the electric heating network 143 is known to those skilled in the art. If the electric current is passed through a resistor and heat is generated, that is, Joule's law (Q = I 2 Rt); when current passes through the electric heating network 143, due to the resistance of the material, the electrical energy is converted into thermal energy, and the free electrons in the metal wire move in a directional manner under the action of the electric field, collide with the metal atoms, and convert the electrical energy into the thermal motion energy of the metal atoms, thereby increasing the temperature of the metal wire;

[0052] The blade 131 is made of aluminum alloy. Since aluminum alloy has good thermal conductivity, the specially treated aluminum alloy tool can balance the hot air temperature to a certain extent and transfer the heat of the hot air in the axial fan 140 more evenly. At the same time, the aluminum alloy has high strength and can withstand the force of metal debris crushing.

[0053] Finally, the specific structure of the transmission component 15 is disclosed. The transmission component 15 includes two rotating shafts 152, which are movably connected to the bracket 2 and the inside of the chassis 11 respectively. A conveyor belt 150 is movably connected between the outer walls of the two rotating shafts 152. The conveyor belt 150 is located directly above the support plate 120, and a plurality of protrusions 151 are fixedly connected to the surface of the conveyor belt 150.

[0054] See also Figure 2 , Figure 3 and Figure 7 As shown, one of the rotating shafts 152 is driven to rotate by the motor output shaft, and under the rotation of the rotating shaft 152, the conveyor belt 150 starts to rotate, so that the conveyor belt 150 can transport the debris on its surface, so that the metal debris enters the collection box 12; at the same time, the multiple protrusions 151 distributed on the conveyor belt 150 support the processing process of the metal product, and facilitate the processed debris to fall into the gaps between the multiple protrusions 151, thereby reducing the sliding force of the debris on the conveyor belt 150; in this way, the powder flying caused by the sliding friction of the metal debris when the conveyor belt 150 is in operation can be reduced;

[0055] Among them, the bump 151 is made of natural rubber. Due to its own characteristics of good elasticity and wear resistance, the bump 151 can buffer the impact force in the metal product processing process to a certain extent, and provide stable and reliable support for the metal product; at the same time, the good wear resistance ensures that the bump 151 is not easy to wear during long-term use, thereby extending its service life; moreover, the natural rubber material of the bump 151 also facilitates the metal product to move smoothly along the movement trajectory of the conveyor belt 150, and the metal product will not be stuck or damaged during the transmission process due to the material being too hard, which provides great convenience for the processing and transportation of metal products.

[0056] Since metal scraps usually contain particles of different sizes, the powdered part of the powdered part is easily affected by factors such as airflow during movement and dumping and is scattered in the air, which not only pollutes the surrounding environment and affects the air quality, but also may bring potential harm to the health of operators. In order to effectively prevent the powder from flying when the metal scraps enter the collection box 12, a plurality of spray guns 21 are fixedly connected to the top of the bracket 2, a water pipe 22 is fixedly connected between the plurality of spray guns 21, and a water pump 23 is fixedly connected to the end of the water pipe 22;

[0057] The water pump 23 starts working, and its powerful power generates a certain pressure. Under the impetus of this pressure, the water in the water pump 23 flows rapidly along the water pipe 22, and the pressurized water is stably delivered to the spray gun 21. The spray gun 21 is designed with a narrow channel and a special nozzle structure. When the high-pressure water flows through the nozzle of the spray gun 21, the cross-sectional area of ​​the nozzle suddenly decreases significantly. According to the Bernoulli principle, the speed of the water flow will increase sharply in an instant, and at the same time, the pressure will be significantly reduced. The high-speed flowing water will interact strongly with the surrounding air. Its powerful kinetic energy draws the air into the water flow. Under this entrainment, the water is torn into extremely fine water droplets, which then form water mist and are ejected from the spray gun 21. In this way, when the metal products being processed are treated, dust can be effectively reduced, and the flying of powder can be avoided to a great extent. Moreover, after the water mist contacts the powder fragments in the metal fragments, the powder fragments have a certain weight, so that when the powder fragments enter the collection box 12, the pollution of the surrounding environment caused by the flying of the powder fragments can be effectively avoided, and the potential harm to the health of the operators is also reduced.

[0058] In summary, the working principle of this solution is as follows:

[0059] First, the water pump 23 generates a certain pressure when it works, which causes the water in the water pump 23 to flow along the water pipe 22. The water pipe 22 delivers the pressurized water to the spray gun 21, which converts the water into water mist and sprays it out to reduce dust on the metal product being processed. This effectively prevents the powder from flying, and increases the weight of the powder in the metal debris to prevent it from floating when entering the collection box 12.

[0060] Secondly, the motor output shaft drives one of the rotating shafts 152 to rotate, thereby driving the conveyor belt 150 to transport the debris on its surface, so that the metal debris can smoothly enter the collection box 12; at the same time, the multiple protrusions 151 on the conveyor belt 150 can support the processing of metal products while reducing the flying of powder caused by the sliding friction of metal debris when the conveyor belt 150 is in operation;

[0061] Furthermore, the motor output shaft drives one of the belt pulleys 132 to rotate, so that the belt 133 rotates and drives the other belt pulley 132 to rotate, and the belt pulley 132 drives the rotating rod 130 to rotate, and the rotating rod 130 drives the shaft 134 and the blade 131 to rotate with the rotating rod 130 as the center, so as to crush the metal debris entering the collection box 12 and turn large debris into multiple small pieces;

[0062] Subsequently, the crushed metal scraps are screened by the sieve plate 141, and small pieces of metal scraps are allowed to pass through the sieve plate 141 and enter between the collection box 12 and the bottom of the sieve plate 141 and the two scrap plates 121; at the same time, the electric heating network 143 is energized to generate heat, and when the axial flow fan 140 blows air through the electric heating network 143, the air is heated and blows out hot air, drying the wet metal scraps inside the collection box 12 and preheating the metal scraps;

[0063] In addition, the axial flow fan 140 is in an intermittent blowing state, which facilitates the metal debris to cycle between the crushing and separation states, and avoids the continuous output of wind force affecting the screening of large and small debris; under the wind force of the axial flow fan 140, the metal debris entering the collection box 12 is blown toward the particle board 122 with the gas flow, and the filter 142 intercepts the block debris in the metal debris blown toward the particle board 122, while the powder particles are blown toward the particle board 122 with the air flow, and are separated from the block debris, so as to realize the classified collection of metal debris;

[0064] Moreover, when the axial flow fan 140 blows, it can generate a clockwise rotation force on the blade 131, causing the blade 131 to flip over on the outer wall of the shaft 134, so that while the blade 131 rotates and crushes, the larger fragments blocked on the top of the screen plate 141 can be moved upward, and then the blocked fragments can be crushed for the second time under the rotation of the blade 131, thereby improving the crushing accuracy.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention.
