Description

Technical Field

[0001] This invention relates to the field of solid waste treatment, and more specifically, to a laser-controlled municipal solid waste crushing device. Background Technology

[0002] Household waste crushing equipment is mainly used to physically crush various types of household waste, such as waste paper, plastic bottles, old furniture, and electronic products, to reduce the volume of waste, facilitate transportation and further processing. Through this equipment, waste reduction, resource recovery and harmlessness can be achieved, waste treatment efficiency can be improved and environmental pollution can be reduced.

[0003] The main crushing structure of a municipal solid waste crushing device is generally two crushing rollers that rotate in opposite directions. The crushing rollers crush the municipal solid waste by squeezing it with their interlocking teeth. However, municipal solid waste contains some waste textiles, which, after being crushed, form tough filamentous waste that may become entangled on the crushing roller shaft. This requires manual cleaning and removal at regular intervals, which is not only time-consuming and labor-intensive, increasing the labor intensity of workers, but also detrimental to the continuous and stable operation of the equipment and reduces its efficiency.

[0004] Laser cleaning technology utilizes the characteristics of lasers to focus a laser beam and instantly generate high temperatures. The surface of an object absorbs the laser energy and heats up rapidly, thus loosening the dirt from the surface. As the temperature rises, the dirt evaporates or ablates, achieving the purpose of removing foreign objects. Furthermore, lasers can process surfaces of various materials and shapes, including metals, non-metals, and complex structural components, depending on the matching of their output energy, making them widely applicable. In view of this, the inventors propose a laser-controlled municipal solid waste crushing device to address the problem of removing attached waste in municipal solid waste crushing devices.

[0041] like Figures 1 to 7 As shown, this embodiment of the invention provides a laser-controlled municipal solid waste crushing device. The device body 100 includes a support leg 101, a housing 102 disposed on the support leg 101, a funnel 103 disposed on the housing 102, and a light source 104 disposed on the funnel 103. The light source 104 includes a first fixed frame 104a disposed on the funnel 103, and a first laser irradiation lamp 104b disposed on the first fixed frame 104a. The device also includes a crushing assembly 200, including a first crushing component 202 and a second crushing component 203 disposed on the funnel 103. The laser light from the light source 104 can pass through the gap between the first crushing component 202 and the second crushing component 203. A laser trigger 201 is disposed on the first crushing component 202.

[0042] The end of the light source 104 is flush with the end of the funnel 103, which allows the light source of the light source 104 to cover the gap between the first crushing part 202 and the second crushing part 203, thereby improving the efficiency of the light source 104 in cutting the waste. The first laser irradiation lamps 104b are arranged in a crisscross pattern, which allows the first laser irradiation lamps 104b to expand the range of the rope-like object wrapped around the first crushing part 202 and the second crushing part 203. This also facilitates the rotation of the first crushing part 202 and the second crushing part 203 towards each other, and makes it easier for the waste to fall into the funnel 103 from the gap between the first crushing part 202 and the second crushing part 203.

[0043] like Figures 3 to 6 As shown, both the first crushing component 202 and the second crushing component 203 include a rotating shaft 202b disposed on the inner wall of the funnel 103. A plurality of moving blades 202a are disposed on the rotating shaft 202b, and a plurality of stationary blades 202c, which can intersect with the moving blades 202a, are disposed on the inner wall of the funnel 103. The laser trigger component 201 includes a first rotating rod 201a disposed at the end of the rotating shaft 202b. A connecting block 201b is disposed on the first rotating rod 201a, and a first sliding groove 201c is formed in the connecting block 201b. The second slide groove 201e is connected to the groove 201c. A second contact head 201i is provided on the inner wall of the end of the first slide groove 201c. A first contact head 201d is slidably sleeved in the first slide groove 201c and passes through the second slide groove 201e. A spring 201g is provided on the first contact head 201d. A limiting hole 201b-1 is opened on the connecting block 201b and is connected to the first slide groove 201c. A slide rod 201h is provided on the first contact head 201d and is slidably sleeved in the limiting hole 201b-1.

[0044] The inner wall of the funnel 103 is provided with a number of stationary blades 202c that can be intersected with the moving blades 202a. This helps to prevent waste from falling into the gaps in the inner wall of the funnel 103 when the moving blades 202a and the stationary blades 202c are on the same horizontal line, thereby improving the crushing efficiency of the first crushing component 202 and the second crushing component 203. The first laser irradiation lamp 104b will emit a laser only when the first contact head 201d comes into contact with the second contact head 201i.

[0045] like Figures 5 to 6 As shown, the end of the spring 201g away from the second contact head 201i is fixedly connected to the inner wall of the end of the second slide groove 201e. The end of the first contact head 201d away from the second contact head 201i is provided with an impact head 201f. A nut is provided on the slide rod 201h. The distance between the inner walls of the limiting holes 201b-1 gradually decreases from end B to end A. An accommodating space is provided inside the housing 102. A receiving component 300 fixedly connected to the bottom end of the funnel 103 is provided in the accommodating space.

[0046] A nut is provided on the slide rod 201h to facilitate the limiting of the first contact head 201d. The distance between the inner walls of the limiting holes 201b-1 gradually decreases from end B to end A, so that when the first crushing part 202 rotates under the drive of the motor, the centrifugal force is used to make the first contact head 201d slide away from the second contact head 201i. In order to increase the resistance of the sliding of the first contact head 201d, the time for the slide rod 201h to slide to end A is increased.

[0047] like Figures 7 to 10 As shown, the receiving component 300 includes a receiving shell 303 disposed at the bottom of the funnel 103, a cleaning component 302 disposed on the receiving shell 303, and a driving component 301 disposed on the cleaning component 302. The driving component 301 includes a second rotating rod 301c, and a fixing cap 301a is disposed at the end of the second rotating rod 301c. A plurality of force-bearing plates 301d are disposed on the fixing cap 301a and evenly arranged around the axis of the fixing cap 301a. A plurality of resistance-increasing blocks 301b are disposed on the striking side of the force-bearing plates 301d. The cleaning component 302 includes a fixing sleeve 302a disposed on the second rotating rod 301c. A plurality of receiving plates 302b are disposed on the fixing sleeve 302a and evenly arranged around the axis of the fixing sleeve 302a.

[0048] The fixed cap 301a is provided with several force-bearing plates 301d evenly arranged around the axis of the fixed cap 301a, which improves the efficiency of the impact head 201f hitting the force-bearing plates 301d to drive the fixed cap 301a and the second rotating rod 301c to rotate. The fixed sleeve 302a is provided with several receiving plates 302b evenly arranged around the axis of the fixed sleeve 302a, which improves the efficiency of the waste falling from the gap between the first crushing part 202 and the second crushing part 203 onto the receiving plates 302b.

[0049] like Figures 7 to 13 As shown, the end of the receiving plate 302b does not abut against the moving blade 202a. The receiving side of the receiving plate 302b is arc-shaped. A shaking sieve assembly 400 is provided inside the housing 102. The shaking sieve assembly 400 includes a stirring element 401. The stirring element 401 includes a second fixing frame 401a provided on the housing 102. A second laser irradiation lamp 401b and a stirring rod 401c are provided on the second fixing frame 401a. Several protrusions are provided on the inner wall of the housing 303. The receiving plate 302b... The end can abut against the inner wall of the housing 303. The housing 102 is also provided with a screening component 402 and a transport component 403. The screening component 402 includes a coarse screen 402a and a fine screen 402b provided on the housing 102. The gap between the top of the housing 303 and the first crushing component 202 and the second crushing component 203 is on the same straight line. The transport component 403 includes a first conveyor belt 403a, a second conveyor belt 403b and a third conveyor belt 403c provided on the housing 102.

[0050] The end of the receiving plate 302b does not contact the moving blade 202a, thus avoiding increasing the obstruction between the receiving plate 302b and the moving blade 202a and reducing the efficiency of the receiving plate 302b in receiving waste. Several protrusions are provided on the inner wall of the receiving shell 303, so that the receiving plate 302b contacts the inner wall of the receiving shell 303 when rotating, causing the receiving shell 303 to vibrate. The top of the receiving shell 303 and the gap between the first crushing member 202 and the second crushing member 203 are on the same straight line, improving the efficiency of waste falling.

[0051] The working process provided by the technical solution of this invention is as follows;

[0052] By setting up a light source 104 and a laser trigger 201, when the operator starts the main body 100 of the device, the first crushing part 202 and the second crushing part 203 rotate towards each other under the drive of the motor. After the garbage is poured into the funnel 103, it is crushed by the mutual squeezing of the first crushing part 202 and the second crushing part 203, and then falls into the gap between the first crushing part 202 and the second crushing part 203. At this time, the light source 104 is activated. At this time, due to the centrifugal force generated by the rotation of the first crushing part 202, the first contact head 201d does not collide with the second contact head 201i. Therefore, the light source 104 is in a standby state and will not emit laser light. When the first crusher 202 and the second crusher 203 are entangled in a rope and cannot rotate, the first contact head 201d slides towards the second contact head 201i under the deformation and reset of the spring 201g until the first contact head 201d abuts against the second contact head 201i. This triggers the laser of the light source 104 to irradiate the first crusher 202 and the second crusher 203 in the interval direction, causing the rope to break. This continues until the first crusher 202 and the second crusher 203 can continue to rotate. The advantage of this setting is that it not only avoids the rope from getting entangled on the rotating shaft, eliminating the need for manual cleaning at regular intervals and reducing the labor intensity of workers, but also improves the operating efficiency of the equipment.

[0053] By setting up the receiving component 300, due to the high temperature characteristics of the laser, when it irradiates the rope-like object, it may reach the ignition point and cause the waste to burn. Therefore, when the rope-like object is broken by the laser, as the first crushing part 202 and the second crushing part 203 continue to rotate from slow to fast, the combustible waste falls from the first crushing part 202 and the second crushing part 203 under the pressure of the crushing part 202 and the second crushing part 203 onto the receiving plate 302b, causing the receiving plate 302b to rotate around the axis of the fixed sleeve 302a. When the receiving plate 302b that has received the waste rotates into the receiving shell 303, another receiving plate 302b will take over the position of the previous receiving plate 302b until the receiving plate 302b that has received the waste rotates to the port of the receiving shell 303 and is limited by the protrusion at the port of the receiving shell 303, and the replacement The receiving plate 302b covers the top of the receiving shell 303, creating an oxygen-deficient environment inside the receiving shell 303 to achieve a fire extinguishing effect. Simultaneously, due to the low speed and inertia of the first crushing component 202 and the second crushing component 203 when they begin to rotate again, the centrifugal force on the laser trigger component 201 is relatively small. This centrifugal force continues until it exceeds the elastic force of the spring 201g, causing the spring 201g to undergo elastic deformation. The first contact head 201d then slides away from the second contact head 201i, disconnecting the electrical connection between the first contact head 201d and the second contact head 201i. Since the distance between the inner walls of the limiting holes 201b-1 gradually decreases from end B to end A, the sliding friction of the first contact head 201d increases, thereby extending the first contact... The sliding time of the head 201d extends the time of the impact head 201f impacting the force plate 301d, thereby extending the rotation time of the receiving plate 302b, and further extending the extinguishing time of the flame inside the receiving shell 303, improving the efficiency of flame extinguishing. As the rotation speed of the first crushing part 202 and the second crushing part 203 increases, after the slide rod 201h abuts against end A of the limiting hole 201b-1, the impact head 201f can impact the force plate 301d, thereby causing the force plate 301d to rotate around the axis of the fixing cap 301a, which in turn causes the receiving plate 302b to rotate around the axis of the fixing sleeve 302a. This causes the receiving plate 302b covering the top of the receiving shell 303 to rotate, pushing the garbage inside the receiving shell 303 out, while simultaneously blocking the receiving shell 303. The receiving plate 302b at the end slides over the protrusion, causing the receiving shell 303 to vibrate, further causing the waste inside the receiving shell 303 to slide out. At this time, waste continues to fall from the gap between the first crushing part 202 and the second crushing part 203 onto the receiving plate 302b. Since the subsequent waste does not require laser irradiation, there is no need for fire extinguishing. After falling into the receiving shell 303, the receiving plate 302b quickly pushes the waste from the receiving shell 303 onto the second fixed frame 401a under the action of the laser trigger 201, and it is stirred by the stirring rod 401c to prevent the waste from clogging. If the rope-like object becomes entangled in the stirring rod 401c, the second laser irradiation lamp 401b is activated to burn the rope-like object. The stirring rod 401c is equipped with a second laser trigger 201.A second receiving component 300 is installed below the second fixed frame 401a. The actions of the first laser trigger 201 and the receiving component 300 are repeated until the waste falls out of the second receiving shell 303 and is screened on the coarse screen 402a below. Waste that passes through the coarse screen 402a falls onto the fine screen 402b, while waste that does not pass through the coarse screen 402a slides down onto the third conveyor belt 403c and is transported out of the shell 102. Waste that passes through the fine screen 402b falls onto the first conveyor belt 403a and is transported out of the shell 102, while waste that does not pass through the fine screen 402b slides down onto the second conveyor belt 403b and is transported out of the shell 102. This arrangement not only avoids the waste being irradiated by the first laser irradiation lamp 104b, thus preventing flames and increasing safety risks, but also allows the waste to be segmented and transported to the next process, alleviating congestion within the shell 102 and improving the crushing efficiency of the main body 100 of the device.
