Description

Technical Field

[0001] The invention belongs to the technical field of energy-saving and environmentally friendly equipment, and in particular relates to a computer motherboard recycling device. Background Art

[0002] The motherboard contains a variety of metals such as copper, aluminum, gold, silver, etc., as well as recyclable materials such as plastics. Through recycling, these resources can be reused to reduce the demand for natural resource mining. In the recycling of computer motherboards, the computer motherboards need to be crushed and ground. Computer motherboards are composed of a variety of materials, including metals (such as copper, aluminum, gold, silver, etc.), plastics, ceramics, etc. Crushing and grinding can separate these different materials for subsequent recycling.

[0003] Different computer motherboards are made of different materials and have different hardnesses. However, the feed speed and crushing power of the equipment used to crush computer motherboards are fixed. When the hardness of the motherboard is relatively high, a relatively fast feed speed will lead to incomplete crushing and equipment overload, and a relatively small crushing power will affect the completeness of the crushing of the computer motherboard. Conversely, when the hardness of the motherboard is relatively low, a too slow feed speed will affect the crushing power, and an excessively large crushing power will cause problems with additional equipment load.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the recycling box, crushing components and automatic control mechanism, the motherboard can be roughly crushed first, and then finer crushing can be carried out to ensure the quality and efficiency of crushing. The crushing power can be adjusted based on the hardness of the motherboard. The greater the hardness of the motherboard, the higher the crushing power, thereby ensuring that sufficient crushing force can be provided to ensure the completeness of the motherboard crushing.

[0014] 2. Through the feed bending mechanism, the mainboard can be fed quickly and bent before being crushed. Bending the mainboard can generate certain stress between different material layers in the mainboard, making it easier to separate during the crushing process, thereby improving the overall crushing effect of the mainboard and making the crushed particles finer and more uniform. In addition, the hardness of the mainboard can be synchronously detected and fed back during the bending process, and the feed speed can be automatically adjusted based on the hardness of the mainboard. The greater the hardness of the mainboard, the lower the feed speed, thereby ensuring that the cutter can fully crush the mainboard and avoiding incomplete crushing of the mainboard or equipment overload due to excessive feeding.

[0015] 3. Through the waste gas treatment mechanism, heating mechanism, filtering mechanism and automatic control mechanism, the waste gas emitted from the mainboard can be treated during the crushing of the mainboard, and the harmful substances therein can be removed to avoid the problem that the waste gas emission causes harm to the environment and human health. The waste gas treatment speed can be automatically adjusted based on the processing speed of the mainboard recycling. The faster the mainboard recycling processing speed is, the more waste gas escapes per unit time, and the faster the waste gas treatment speed is. The waste gas can be heated during the waste gas treatment, so that the volatile substances in the mainboard are easier to separate from the waste gas, which is convenient for better treatment of harmful substances. The heating temperature is automatically adjusted based on the waste gas treatment speed. The faster the waste gas treatment speed is, the higher the heating temperature is, so that the waste gas can be completely heated in place, so that the treatment quality of the waste gas is better. After the treated waste gas is heated, the crushed mainboard can be dried, so that the moisture in the mainboard crushing material is removed, and the adhesion between the crushed particles is reduced, so that the material can be separated more smoothly in the subsequent separation and processing equipment, thereby improving the separation quality.

[0016] 4. Through the set warning mechanism, the service life of the activated carbon adsorption component in the filtering mechanism can be automatically calculated, and the staff can be automatically reminded to replace it after the threshold of the service life of the activated carbon adsorption component is reached, ensuring the effective treatment of the waste gas generated during the motherboard crushing process, and the triggering time of the warning mechanism can be automatically corrected based on the waste gas treatment speed. The faster the waste gas treatment speed, the higher the degree of filtering work of the activated carbon adsorption component, shortening the triggering interval of the warning mechanism, making the replacement of the activated carbon adsorption component more timely.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figure 1-Figure 8 As shown, a computer motherboard recycling device includes a recycling box 1 and also includes: The crushing assembly 2 is installed inside the recycling box 1.

[0021] The feed bending mechanism 3 is installed at the top feed port of the recycling box 1. The feed bending mechanism 3 includes two support brackets 31 which are symmetrically fixed on the upper end of the recycling box 1.

A feed conveyor belt 38 is provided on one side of the support bracket 31, which can be bent before the main board is crushed. Bending the main board can generate a certain stress between different material layers in the main board, which makes it easier to separate during the crushing process, thereby improving the overall crushing effect of the main board and making the crushed particles finer and more uniform.

[0022] The waste gas treatment mechanism 4 is fixedly connected to the side wall of the recycling box 1. The waste gas treatment mechanism 4 includes a plurality of exhaust heads 41 which are arranged in a ring-shaped distribution and fixedly inserted in the upper side wall of the recycling box 1. The lower side wall of the recycling box 1 is evenly fixedly inserted with a plurality of drying heads 42. The outer ends of the plurality of exhaust heads 41 are fixedly connected to the same exhaust shell 43. The outer ends of the plurality of drying heads 42 are fixedly connected to the same drying shell 44. A circulation pipe 45 is fixedly connected between the exhaust shell 43 and the drying shell 44.

A heating mechanism 6 and a filtering mechanism 7 are also installed on the circulation pipe 45. A warning mechanism 8 is also fixedly installed on the outer wall of the recycling box 1. The waste gas emitted from the main board can be treated in the process of crushing the main board to remove harmful substances therein, thereby avoiding the problem of waste gas emission causing harm to the environment and human health.

[0023] The heating mechanism 6 includes a heating shell 61, in which a plurality of electric heating rods 62 are fixedly installed, which can heat the exhaust gas during the exhaust gas treatment process, thereby making it easier to separate the volatile substances in the mainboard from the exhaust gas, thereby facilitating better treatment of harmful substances.

[0024] The filter mechanism 7 comprises a filter shell 71, in which an activated carbon adsorption component 72 is installed, which can efficiently process the exhaust gas and prevent the harmful substances in the exhaust gas from escaping and causing harm to the human body and the environment.

[0025] The warning mechanism 8 includes a warning shell 81, in which a reciprocating screw 82 is rotatably connected, a servo motor 83 for driving the reciprocating screw 82 to rotate is fixedly installed on the outer wall of the warning shell 81, a movable plate 84 is threadedly sleeved on the rod wall of the reciprocating screw 82, a warning switch 85 arranged opposite to the movable plate 84 is fixedly installed on one side of the inner wall of the warning shell 81, an alarm 86 is fixedly installed on the outer wall of the warning shell 81, a limit slider is fixedly installed on one side of the movable plate 84, and a limit slide groove matching the limit slider is provided on the inner wall of the warning shell 81, which can automatically calculate the service life of the activated carbon adsorption component 72 in the filtering mechanism 7, and automatically remind the staff to replace it after reaching the threshold of the service life of the activated carbon adsorption component 72, thereby ensuring effective treatment of the exhaust gas generated during the mainboard crushing process.

[0026] The automatic regulating mechanism 5 is fixedly mounted on the outer wall of the recycling box 1 and is electrically connected to the feeding bending mechanism 3. The automatic regulating mechanism 5 includes a regulating shell 51. An adjusting screw 52 is rotatably connected to one side of the inner wall of the regulating shell 51. An adjusting motor 53 for driving the adjusting screw 52 to rotate is fixedly mounted on the outer wall of the regulating shell 51. A first feedback resistor rod 54 and a second feedback resistor rod 55 arranged in parallel with the adjusting screw 52 are fixedly mounted on the inner wall of the regulating shell 51. An adjusting seat 56 is threadedly sleeved on the rod wall of the adjusting screw 52. A sleeve hole sleeved outside the first feedback resistor rod 54 and the second feedback resistor rod 55 is opened on the surface of the adjusting seat 56. A first feedback conductive contact piece 57 and a second feedback conductive contact piece 58 that are respectively in electrical contact with the first feedback resistor rod 54 and the second feedback resistor rod 55 are fixedly mounted on the inner wall of the corresponding sleeve hole of the adjusting seat 56. A plurality of regulating switches 59 are also fixedly mounted at equal intervals on the inner wall of the regulating shell 51. A pressing round head 510 corresponding to the position of the regulating switch 59 is fixedly mounted on one side of the regulating seat 56.

[0027] The PLC controller 9 is fixedly mounted on the outer wall of the recovery box 1 and is electrically connected to the crushing assembly 2, the feed bending mechanism 3, the waste gas treatment mechanism 4 and the automatic control mechanism 5 respectively.

[0028] The operating principle of the present invention is described as follows: the computer motherboard to be recycled is conveyed to the support frame 31 by the feed conveyor belt 38, and is stopped by the stopper 32 to limit the position, so that the computer motherboard is stably placed on the support frame 31, and the PLC controller 9 controls the electric push rod 34 to push the pressure plate 35 and the bending plate 36 downward, thereby bending the motherboard, and the bending force of the bending plate 36 on the motherboard is fed back to the pressure detection plate 37. The greater the hardness of the motherboard, the greater the pressure sensed by the pressure detection plate 37, and the pressure detection plate 37 feeds back the detected pressure signal to the PLC controller 9; The PLC controller 9 controls the action of the regulating motor 53 based on the pressure signal fed back by the pressure detection plate 37. The greater the hardness of the main board, the greater the detection pressure signal of the pressure detection plate 37, and thus the PLC controller 9 controls the regulating motor 53 to rotate for a longer time, and the regulating motor 53 drives the regulating screw 52 to rotate. Through the threaded sleeve effect of the regulating screw 52 and the regulating seat 56, the regulating seat 56 drives the first feedback conductive contact piece 57, the second feedback conductive contact piece 58 and the pressing round head 510 to move synchronously, and thus the first feedback conductive contact piece 57 on the first feedback resistor rod 54 and the second feedback conductive contact piece 58 on the second feedback resistor rod 55 slide longer, so that the resistance value of the first feedback resistor rod 54 is larger, the resistance value of the second feedback resistor rod 55 is smaller, and the pressing round head 510 can act on the regulating switch 59 at the lower side; The first feedback conductive contact piece 57 and the first feedback resistor rod 54 are connected in series to the power supply circuit of the electric roller pressing assembly 21. The greater the hardness of the main board, the greater the access resistance of the first feedback resistor rod 54, which in turn makes the working speed of the electric roller pressing assembly 21 slower, thereby reducing the feeding speed. The second feedback conductive contact piece 58 and the second feedback resistor rod 55 are connected in series to the power supply circuit of the bidirectional drive assembly 24. The greater the hardness of the main board, the smaller the access resistance of the second feedback resistor rod 55, which in turn makes the power of the bidirectional drive assembly 24 driving the crushing rod 22 and the crushing blade 23 to crush greater, thereby ensuring the complete crushing of the main board; When the motherboard is crushed, the PLC controller 9 controls the circulation pump 46 to work, and the circulation pump 46 cooperates with the circulation pipe 45 to provide negative pressure suction force in the exhaust head 41, and transports air to the crushing position of the motherboard to dry the crushed motherboard. The electric heating rod 62 in the heating shell 61 can heat the absorbed exhaust gas, so that the volatile substances in the exhaust gas can be volatilized better. The exhaust gas then enters the filter shell 71, and after being adsorbed by the activated carbon adsorption component 72 in the filter shell 71, hot air is ejected through the drying head 42 to dry the crushed motherboard. When the adjustment switch 59 on the lower side is pressed and triggered as the hardness of the main board increases, the PLC controller 9 controls the circulation pump 46 to work at a slower power. Because the feeding speed is slow when the hardness of the main board is large, the amount of the main board crushed per unit time is small, so that the amount of waste gas in the main board is small, and a small air circulation can be used to process the waste gas, saving energy. The first feedback conductive contact 57 and the first feedback resistor rod 54 are also connected in series to the power supply circuit of the electric heating rod 62. When the hardness of the main board is large, the access resistance of the first feedback resistor rod 54 is large, and the power supply current of the electric heating rod 62 is small, and thus the heating temperature is low, which is suitable for heating the waste gas when less waste gas is processed, saving energy. When performing waste gas treatment, the PLC controller 9 controls the servo motor 83 to work synchronously, and the servo motor 83 drives the reciprocating screw 82 to rotate. The threaded sleeve of the reciprocating screw 82 and the movable plate 84 enables the movable plate 84 to move in the warning shell 81 until the movable plate 84 presses on the warning switch 85. The warning switch 85 controls the alarm 86 to sound, thereby reminding the staff that the activated carbon adsorption component 72 in the filter shell 71 needs to be replaced, and the first feedback conductive contact piece 57 and the first feedback resistor rod 54 are also connected in series to the power supply circuit of the servo motor 83. When the hardness of the main board is greater, the access resistance of the first feedback resistor rod 54 is greater, and the speed of the servo motor 83 is slower. Because the waste gas treatment speed is low at this time, the adsorption degree of the activated carbon adsorption component 72 is reduced, so that the service life of the activated carbon adsorption component 72 is prolonged, and the service life of the activated carbon adsorption component 72 can be calculated more accurately, avoiding the problem of waste of resources caused by too frequent replacement and the problem of untimely replacement affecting the quality of waste gas treatment.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
