Description

Technical Field

[0001] The present invention relates to the technology of waste circuit board treatment, and specifically to an incineration conveying device for waste circuit board debris. Background Art

[0002] The circuit board contains rich precious metals, such as gold, silver, copper, etc. Its gold content is 40 to 800 times that of mined ore, and its copper content is 30 to 40 times that of mined ore. Recycling circuit boards can not only extract these precious metals, reduce resource waste, but also reduce the dependence on mineral resources, and at the same time reduce environmental pollution. Incineration is one of the main methods for treating waste circuit boards at present. Through incineration, the organic substances (such as plastics and resins) in the circuit board can be decomposed, and at the same time, the metal components can be separated. The incinerated metals can be further extracted through pyrometallurgy or hydrometallurgy to reduce resource waste and the heavy metal pollution caused to the ecological environment. When incinerating the circuit board, the circuit board waste is directly fed into the incinerator under the conveyance of the conveyor belt. This direct connection setting makes the material dropping of the circuit board waste relatively concentrated, resulting in excessive incineration pressure at the corresponding position in the incinerator, causing incomplete combustion of the waste, affecting the incineration efficiency, and bringing inconvenience to the subsequent extraction of metal components by users. Therefore, an incineration conveying device for waste circuit board debris is proposed. Summary of the Invention

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0031] Please refer to Figure 1-4 , an embodiment of the present invention provides a technical solution: including a conveyor mechanism 100 and an incinerator mechanism 200.

[0032] Specifically, the conveyor mechanism 100 includes a conveyor belt 101 for conveying circuit board waste to the incinerator, and a transition piece 102 is installed at one end of the conveyor belt 101, and a crushing piece 103 is installed inside the transition piece 102.

[0033] The incinerator mechanism 200 can incinerate circuit board waste.

[0034] Furthermore, the transition piece 102 includes a transition hopper 102a fixed to one end of the conveyor belt 101. One side of the top of the transition hopper 102a is fixedly provided with an inclined guide plate 102b, and a sorting opening 102c for small pieces of waste to pass through is provided on the guide plate 102b. And a discharge opening 102d is provided at the bottom of the transition hopper 102a, and the circuit board waste enters the incinerator through the discharge opening 102d.

[0035] A positioning groove 102e is also provided on the inner wall of the discharge opening 102d.

[0036] The crushing member 103 includes a crushing cylinder 103a fixed above the interior of the transition hopper 102a. An inlet for large circuit board waste is provided on the outer wall of the crushing cylinder 103a on the side in contact with the guiding plate 102b. An opening 103b is provided at the bottom of the crushing cylinder 103a, and the width of the opening 103b is the same as that of the sorting opening 102c, so that the crushed circuit board waste can fall automatically. A crushing roller 103c is also installed inside the crushing cylinder 103a, and a motor 103d is connected to the outside of the crushing roller 103c.

[0037] During use, the waste is transferred onto the guiding plate 102b by the conveyor belt 101. At this time, the waste with a smaller size can directly fall into the interior of the transition hopper 102a through the sorting opening 102c, while the waste with a larger size is guided by the guiding plate 102b into the crushing cylinder 103a. At this time, the motor 103d is started, and the motor 103d drives the crushing roller 103c to rotate to crush the large waste. The waste crushed to a suitable size can enter the transition hopper 102a through the opening 103b at the bottom of the crushing cylinder 103a, and then enter the incinerator through the material dropping opening 102d for incineration and recycling.

[0038] In summary, through the arrangement of the crushing member 103 and the guiding plate 102b, larger waste can be sorted and re-crushed to reduce the volume of the waste, facilitating the subsequent incineration treatment of the waste and avoiding incomplete incineration due to the excessive size of the waste.

[0039] Please refer to Figure 1-6 , the embodiment of the present invention provides a technical solution: including a transmission member 104 and a rotation member 105.

[0040] Specifically, the conveying mechanism 100 further includes a transmission member 104 located outside the crushing member 103, and a rotation member 105 is connected to the outside of the transmission member 104.

[0041] Furthermore, the transmission member 104 includes a transmission wheel 104a installed at one outer end of the crushing roller 103c. A belt 104b is arranged on the outside of the transmission wheel 104a, and the other end of the belt 104b is connected to a linkage wheel 104c. The linkage wheel 104c can rotate synchronously with the transmission wheel 104a through the belt 104b.

[0042] The rotating part 105 includes a driving rod 105a installed at the lower part of the transition bucket 102a, and a return groove 105b is left on the outer wall of the driving rod 105a. A sliding sleeve 105c is provided on the outside of the driving rod 105a, and a sliding head 105d is fixed to the inner wall of the sliding sleeve 105c. A closing plate 105e is connected to the bottom of the sliding sleeve 105c, and the closing plate 105e is located in the blanking port 102d. The closing plate 105e is engaged with the positioning groove 102e, so that the closing plate 105e can slide in the blanking port 102d. At the same time, under the setting of the positioning groove 102e, the closing plate 105e can be restricted to prevent the closing plate 105e from detaching from the blanking port 102d.

[0043] The linkage wheel 104c is installed on the driving rod 105a, so that under the transmission of the belt 104b, the driving rod 105a and the crushing roller 103c can be rotated synchronously, thereby achieving the purpose of moving the closing plate 105e on the blanking port 102d.

[0044] Preferably, the return groove 105b is arranged in a ring-shaped connection on the outer wall of the driving rod 105a, and the return groove 105b and the sliding head 105d are slidably matched, so that when the driving rod 105a rotates, the groove wall of the return groove 105b can push the sliding head 105d, so that the closing plate 105e limited by the positioning groove 102e can move inside the blanking port 102d. At the same time, under the connection setting of the return groove 105b, the closing plate 105e can reciprocate in the blanking port 102d with the continuous rotation of the driving rod 105a, so that the middle section and both ends of the blanking port 102d can be opened alternately, so that the circuit board waste can fall into the incinerator from different positions of the blanking port 102d in an orderly manner, avoiding the waste from falling in a certain position and bringing a burning burden to the incinerator, reducing the possibility of incomplete combustion of the waste, and improving the incineration efficiency.

[0045] When in use, as the motor 103d is started, the driving rod 105a rotates synchronously with the driving wheel 104a on the crushing roller 103c under the transmission of the belt 104b and the linkage wheel 104c, so that the closing plate 105e moves back and forth inside the material drop opening 102d under the cooperation of the return groove 105b and the sliding head 105d, and then the two ends and the middle section of the material drop opening 102d can be continuously opened alternately, and the circuit board waste can fall in order from different positions of the material drop opening 102d, so as to facilitate the subsequent incineration of the waste in the incinerator.

[0046] In summary, through the cooperative setting of the rotating part 105, the transmission part 104, and the crushing part 103, while the crushing part 103 performs secondary crushing on large waste materials, the rotating part 105 can operate synchronously with the crushing part 103 under the drive of the transmission part 104, so that the opening position of the blanking port 102d is always in a changing state, that is, the two ends and the middle section of the blanking port 102d can be continuously opened alternately, thereby avoiding the incomplete burning caused by the concentrated falling of waste materials, achieving the purpose of more complete burning of waste materials, and making it more convenient for users to recycle the old metals after burning the circuit board waste materials.

[0047] Please refer to Figure 1-7 , in another embodiment provided by the present invention, it includes a sorting part 106, a control groove 107, and a synchronization rod 108.

[0048] Specifically, the conveying mechanism 100 further includes sorting parts 106 installed on both sides of the bottom of the transition part 102. The two sorting parts 106 are arranged in parallel, and control grooves 107 are provided at the tops of the two sorting parts 106. At the same time, a synchronization rod 108 is installed between the two sorting parts 106.

[0049] Furthermore, the sorting part 106 includes connecting seats 106a fixed at both ends of the bottom of the transition hopper 102a. A sorting plate 106b is arranged between the two connecting seats 106a. The sorting plate 106b is in hinge cooperation with the connecting seats 106a. Thus, through the angular deflection of the sorting plate 106b, the circuit board waste materials falling through the blanking port 102d can be deflected and guided to guide the circuit board waste materials to different positions in the incinerator.

[0050] The control groove 107 is provided at the top of the sorting plate 106b. The control groove 107 includes a first inclined groove 107a. One end of the first inclined groove 107a is communicated with a second inclined groove 107b. At the same time, a control head 105f is also provided at the bottom of the closing plate 105e. The control head 105f can be in sliding cooperation with the first inclined groove 107a and the second inclined groove 107b respectively.

[0051] Preferably, the first inclined groove 107a and the second inclined groove 107b are symmetrically arranged with respect to the end point of the first inclined groove 107a, that is, the inclination directions of the first inclined groove 107a and the second inclined groove 107b are opposite. Thus, when the control head 105f moves translationally along with the closing plate 105e, the control head 105f can act on the groove wall of the first inclined groove 107a or the second inclined groove 107b. Thereby, the turning of the diverter plate 106b can be realized under the cooperation of the control head 105f and the control groove 107. And with the reverse arrangement of the first inclined groove 107a and the second inclined groove 107b, in cooperation with the reciprocating closing plate 105e, the reciprocating turning of the diverter plate 106b is realized to better achieve the diversion and guiding effect of the diverter plate 106b on the waste. At the same time, the projections of the first inclined groove 107a and the second inclined groove 107b on the top of the diverter plate 106b are both one-fourth of its perimeter. Thus, under the respective cooperation of the control head 105f with the first inclined groove 107a and the second inclined groove 107b, the diverter plate 106b can swing reciprocally by 90°, that is, the guiding angles on both sides are 45° respectively.

[0052] Furthermore, both ends of the synchronizing rod 108 are respectively hinged to two diverter plates 106b. Thus, when the diverter plate 106b with the control groove 107 at the top turns, the other diverter plate 106b can be pushed by the synchronizing rod 108 to turn synchronously, so as to ensure that the two diverter plates 106b are always in a parallel state and prevent the falling of the waste from being affected.

[0053] During use, with the horizontal movement of the closing plate 105e, the control head 105f moves in the control groove 107, so that the diverter plate 106b can swing along with the translation of the closing plate 105e, and the synchronous swinging of the two diverter plates 106b is maintained by means of the synchronizing rod 108. Thus, the waste can be guided laterally by the left and right swinging of the diverter plate 106b, so that the waste can uniformly fall from the blanking port 102d to various parts inside the incinerator, preventing the concentrated falling of the waste.

[0054] In summary, through the linkage cooperation between the control head 105f and the control groove 107, the diverter plate 106b can swing reciprocally along with the reciprocating translation of the closing plate 105e, so that the waste can also fall to both sides of the incinerator, making the waste as evenly distributed as possible inside the incinerator and preventing incomplete incineration caused by the concentrated falling of the waste. This kind of setting enables the waste to burn fully, making it more convenient for the user to recycle the residual waste metal after incineration.

[0055] Only some exemplary embodiments of the present invention have been described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
