Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, and in particular to an energy-saving crushing device for construction waste used in brick making. Background Technology

[0002] Energy-saving crushing equipment for brick-making construction waste is a specialized device used to crush construction waste (such as waste bricks, concrete, and tiles) while achieving energy savings during the crushing process. This type of equipment plays a vital role in the recycling and reuse of construction waste, particularly in the fields of green building and resource recycling, helping to reduce waste emissions while conserving energy.

[0003] However, existing energy-saving crushing devices for brick-making construction waste often lack effective dust suppression systems during the waste processing process. This results in the rapid dispersion of particles into the air as the waste is violently impacted and rubbed during crushing. These fine dust particles not only create dense dust smog around the equipment, causing air pollution, but also pose a serious threat to the health of workers. Long-term exposure to high concentrations of dust can easily lead to respiratory diseases, especially pneumoconiosis and bronchitis. Harmful substances in the dust can also irritate the skin, eyes, and other parts of the body, and even affect the overall health of long-term workers. In the absence of protective measures, workers may not be able to effectively avoid the harmful effects of these substances. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of the lack of effective dust suppression devices in the prior art. This leads to the problem that when construction waste is put into the crushing equipment, the particles are not only quickly dispersed into the air due to the violent collision and friction of the material during the crushing process, but also pose a serious threat to the health of the workers.

[0011] In the above technical solution, preferably, a water tank is provided on the top of the base plate, the water tank is located at the bottom of the water outlet pipe, and a pump is fixedly installed on the rear side of the water tank.

[0012] In the above technical solution, preferably, a water inlet pipe is fixedly installed on the top of the pump, and multiple nozzles are provided at the other end of the water inlet pipe. All of the multiple nozzles are fixedly installed on the top side of the inner wall of the device body.

[0013] In the above technical solution, preferably, a cover plate is slidably connected to the inside left side of the device body, four second telescopic rods are fixedly installed on the top right side of the base plate, and four second return springs are fixedly installed on the top right side of the base plate.

[0014] In the above technical solution, preferably, a tray is fixedly installed at the other end of the four second reset springs and the four second telescopic rods, and a collection box is provided on the top of the tray, the collection box being located at the bottom right side of the drainage plate.

[0015] In the above technical solution, preferably, push rods are fixedly installed on both sides of the bottom of the tray, air cylinders are movably sleeved on the outer surface of the two push rods, the two air cylinders are fixedly installed on the top of the base plate, and pistons are provided at the bottom of the two push rods.

[0016] In the above technical solution, preferably, both pistons are slidably connected inside the air cylinder, and a first air pipe is provided at the bottom of both air cylinders.

[0017] In the above technical solution, preferably, a second air pipe is provided at the other end of the two first air pipes, and a first support column is provided at the other end of the second air pipe. The outer surface of the first support column is fixedly embedded in the inner top side of the device body.

[0018] In the above technical solution, preferably, a second support column is slidably connected inside the first support column, and a third return spring is fixedly installed on the top of the second support column.

[0019] In the above technical solution, preferably, the other end of the third reset spring is fixedly installed on the top side of the inner wall of the first support column, and a pressure plate is fixedly installed at the bottom of the second support column, the pressure plate being slidably connected inside the device body.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0021] 1. In this embodiment of the invention, personnel can first slide the cover upwards, then put waste into the device body and inject clean water into the water tank on the bottom plate. Then, personnel can start the motor via the power supply system, enabling it to drive the first rotating rod on the right side through the output shaft, and the first rotating rod on the right side to drive the first rotating rod on the left side through gears, thereby driving the two crushing rollers to rotate relative to each other to crush the waste. During crushing, personnel can start the pump via the power supply system, enabling it to draw water from the water tank and inject it into the nozzle through the water inlet pipe. Water can then be sprayed onto the inside of the device body through the nozzle to reduce dust. The crushed waste falls onto the top of the guide plate through the crushing rollers and is diverted to the right by the angle of the guide plate to fall into the collection box. The sprayed water can pass through the slots on the guide plate. The water falls onto the filter plate, where it is filtered to remove impurities. The filtered water then flows back into the water tank through the outlet pipe for reuse. The filter plate and nozzle design not only evenly spray water into the equipment, suppressing dust generated during the crushing process and protecting workers' health, but also improves the working environment and reduces harmful particulate matter in the air. Furthermore, the sprayed water falls through slots on the guide plate back to the top of the filter plate and, after filtration, flows back into the water tank for reuse. This not only saves water resources but also reduces water consumption, solving the problem of the lack of effective dust suppression devices in existing technologies. Previously, when construction waste was fed into the crushing equipment, the violent collisions and friction during crushing caused particles to be rapidly dispersed into the air, posing a serious threat to workers' health.

[0022] 2. In this embodiment of the invention, when the first rotating rod on the left side rotates, it can be driven by the first synchronous pulley to the synchronous belt, and the synchronous belt drives the second rotating rod to rotate through the second synchronous pulley. The second rotating rod then drives the eccentric wheel to rotate in a circle. When the eccentric wheel reaches the top, it pushes the filter plate upwards, and the filter plate pulls the first telescopic rod and the first return spring to extend. When the eccentric wheel rotates to the bottom, the first telescopic rod and the first return spring reset, and simultaneously pull the filter plate downwards. The reciprocating rotation of the eccentric wheel drives the filter plate to reciprocate up and down, shaking off impurities from the filter plate. These impurities are then allowed to roll to the left and exit the device body through the angled movement of the filter plate. The structure of the second rotating rod and the eccentric wheel allows the filter plate to automatically shake off impurities, reducing manual intervention, improving the system's automation and efficiency, maintaining high filtration efficiency, ensuring clean water returns to the water tank, improving water recycling efficiency, and reducing resource waste.

[0023] 3. In this embodiment of the invention, when the pulverized waste falls into the collection box, it can press down on the tray by its own weight, and the tray squeezes the second telescopic rod and the second return spring to retract, thereby causing the tray to drive the collection box to descend. When the tray descends, the piston can be pushed down inside the air cylinder by the push rod. When the piston slides, it can squeeze the air inside the air cylinder, so that the air can enter the interior of the first support column through the first air pipe and the second air pipe. When the air enters the interior of the first support column, it can push the second support column down inside the first support column by air pressure, and at the same time pull the third return spring to extend. Then, when the second support column slides, it can push the pressure plate down inside the device body to squeeze the waste, so that the waste can fit more closely to the pulverizing roller. Through the setting of the air cylinder and pressure plate structure, the waste can be squeezed, making the waste fit more tightly to the pulverizing roller, which helps to improve the pulverization effect of the waste, so that the waste can be pulverized more evenly and thoroughly, optimize the waste processing efficiency, and accelerate the waste processing process.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-11This embodiment provides a technical solution: an energy-saving crushing device for brick-making construction waste, including a device body 1. Two first rotating rods 101 are movably embedded in the inner sides of the device body 1. Gears 102 are fixedly installed on the front sides of both first rotating rods 101, and the two gears 102 mesh with each other. The device also includes: crushing rollers 103 fixedly sleeved on the outer surfaces of both first rotating rods 101; a motor 104 fixedly installed on the rear side of one first rotating rod 101, with the bottom of the motor 104 fixedly installed on the rear top of the device body 1; and a first synchronous wheel 109 fixedly sleeved on the rear outer surface of the other first rotating rod 101; a diversion plate 105 fixedly embedded inside the device body 1, with multiple slots 203 inside the diversion plate 105; and a filter plate 106 movably embedded in... Inside the device body 1, first telescopic rods 107 are fixedly installed around the bottom of the filter plate 106, and first return springs 108 are fixedly installed around the bottom of the filter plate 106. The other ends of the four first return springs 108 and the four first telescopic rods 107 are fixedly installed inside the device body 1. A second rotating rod 110 is movably embedded inside the device body 1. A second synchronous wheel 111 is fixedly sleeved on the rear outer surface of the second rotating rod 110. The first synchronous wheel 109 and the second synchronous wheel 111 are connected by a synchronous belt 112. An eccentric wheel 119 is fixedly sleeved on the outer surface of the second rotating rod 110. The eccentric wheel 119 is movably connected to the bottom of the filter plate 106. A water outlet pipe 113 is fixedly installed at the bottom of the device body 1. A base plate 114 is provided at the bottom of the device body 1.

[0039] In use, personnel can first slide the cover plate 2 upwards, then put waste into the device body 1, and fill the water tank 115 on the bottom plate 114 with clean water. Then, personnel can start the motor 104 through the power supply system of the motor 104, so that when it is running, it can transmit power to the first rotating rod 101 on the right side through the output shaft, and the first rotating rod 101 on the right side can transmit power to the first rotating rod 101 on the left side through the gear 102, thereby driving the two crushing rollers 103 to rotate relative to each other to crush the waste. During crushing, personnel can start the pump 116 through the power supply system of the pump 116. During operation, the system draws water from the water tank 115 and injects it into the nozzle 118 through the water inlet pipe 117. The nozzle 118 sprays water into the interior of the device body 1 to suppress dust. The pulverized waste falls through the pulverizing roller 103 onto the top of the guide plate 105, and is then diverted to the right by the inclined angle of the guide plate 105, falling into the collection box 205. The sprayed water falls through the slots 203 on the guide plate 105 onto the filter plate 106, where it is filtered to remove impurities. The filtered water can flow back into the water tank 115 through the outlet pipe 113 for recycling. The structure of the filter plate 106 and the nozzle 118 not only allows water to be sprayed evenly into the equipment, suppressing dust generated during the crushing process, protecting the health of workers, improving the working environment, and reducing harmful particulate matter in the air, but also allows the sprayed water to fall into the top of the filter plate 106 through the slot 203 on the guide plate 105, and then flow back into the water tank 115 for recycling after filtration. This not only saves water resources but also reduces water consumption.

[0040] Please see Figures 1 to 11 In one embodiment, a water tank 115 is provided on the top of the base plate 114. The water tank 115 is located at the bottom of the water outlet pipe 113. A pump 116 is fixedly installed on the rear side of the water tank 115. The pump 116 can be started through the power supply system of the pump 116 so that it can pump out the water inside the water tank 115 when it is running.

[0041] Please see Figures 1 to 11 In one embodiment, a water inlet pipe 117 is fixedly installed on the top of the pump 116, and a plurality of nozzles 118 are provided at the other end of the water inlet pipe 117. The plurality of nozzles 118 are fixedly installed on the top side of the inner wall of the device body 1, so that water can be injected into the interior of the nozzles 118 through the water inlet pipe 117, and water can be sprayed on the interior of the device body 1 through the nozzles 118 to reduce dust.

[0042] Please see Figures 1 to 11In one embodiment, a cover plate 2 is slidably connected to the left side of the device body 1, and four second telescopic rods 201 are fixedly installed on the top right side of the base plate 114. Four second return springs 202 are fixedly installed on the top right side of the base plate 114. The second telescopic rods 201 and the second return springs 202 can be compressed by the tray 204 to retract them.

[0043] Please see Figures 1 to 11 In one embodiment, a tray 204 is fixedly installed at the other end of four second return springs 202 and four second telescopic rods 201. A collection box 205 is provided on the top of the tray 204. The collection box 205 is located at the bottom right side of the guide plate 105, so that the crushed waste can fall onto the top of the guide plate 105 through the crushing roller 103, and be guided to the right by the inclined angle of the guide plate 105 to fall into the interior of the collection box 205.

[0044] Please see Figures 1 to 11 In one embodiment, push rods 207 are fixedly installed on both sides of the bottom of the tray 204. Air cylinders 206 are movably sleeved on the outer surface of the two push rods 207. The two air cylinders 206 are fixedly installed on the top of the base plate 114. Pistons 208 are provided at the bottom of the two push rods 207. When the tray 204 is lowered, the pistons 208 can be pushed by the push rods 207 to slide downward inside the air cylinders 206.

[0045] Please see Figures 1 to 11 In one embodiment, both pistons 208 are slidably connected inside the air cylinder 206. The bottom of both air cylinders 206 is provided with a first air pipe 209, so that when the pistons 208 slide, they can squeeze the air inside the air cylinder 206, so that the air can enter the interior of the first support column 211 through the first air pipe 209 and the second air pipe 210.

[0046] Please see Figures 1 to 11 In one embodiment, a second air pipe 210 is provided at the other end of the two first air pipes 209, and a first support column 211 is provided at the other end of the second air pipe 210. The outer surface of the first support column 211 is fixedly embedded in the inner top side of the device body 1, so that when air enters the first support column 211, the second support column 212 can be pushed downward inside the first support column 211 by air pressure.

[0047] Please see Figures 1 to 11 In one embodiment, a second support column 212 is slidably connected inside the first support column 211, and a third return spring 213 is fixedly installed on the top of the second support column 212, so that the third return spring 213 can be extended by pulling the second support column 212.

[0048] Please see Figures 1 to 11 In one embodiment, the other end of the third reset spring 213 is fixedly installed on the top side of the inner wall of the first support column 211, and a pressure plate 214 is fixedly installed at the bottom of the second support column 212. The pressure plate 214 is slidably connected inside the device body 1, so that when the second support column 212 slides, it can push the pressure plate 214 to descend inside the device body 1 to squeeze the waste material, so that the waste material can fit more closely to the crushing roller 103.

[0049] Working principle: During use, personnel can first slide the cover plate 2 upwards, then put waste into the device body 1, and inject clean water into the water tank 115 on the bottom plate 114. Then, personnel can start the motor 104 through the power supply system of the motor 104. When running, the motor 104 can transmit power to the first rotating rod 101 on the right side through the output shaft, and the first rotating rod 101 on the right side can transmit power to the first rotating rod 101 on the left side through the gear 102, thereby driving the two crushing rollers 103 to rotate relative to each other to crush the waste. During crushing, personnel can start the pump 116 through the power supply system of the pump 116. This allows the system to draw water from the water tank 115 during operation and inject it into the nozzle 118 through the water inlet pipe 117. The nozzle 118 then sprays water into the interior of the device body 1 to suppress dust. The pulverized waste falls through the pulverizing roller 103 onto the top of the guide plate 105, and is then diverted to the right by the angle of the guide plate 105, falling into the collection box 205. The sprayed water falls through the slots 203 on the guide plate 105 onto the filter plate 106, where it is filtered to remove impurities. The filter plate 106 and nozzle 118 are designed to ensure that the filtered water can flow back into the water tank 115 for recycling through the outlet pipe 113. The filter plate 106 and nozzle 118 not only spray water evenly into the equipment, suppressing dust generated during the crushing process, protecting the health of workers, improving the working environment, and reducing harmful particulate matter in the air, but also allow the sprayed water to fall into the top of the filter plate 106 through the slot 203 on the guide plate 105, and then flow back into the water tank 115 for recycling after filtration. This not only saves water resources but also reduces water consumption.In use, when the first rotating rod 101 on the left rotates, it drives the timing belt 112 via the first synchronous pulley 109. The timing belt 112 then drives the second rotating rod 110 to rotate via the second synchronous pulley 111. The second rotating rod 110 then drives the eccentric wheel 119 to rotate in a circle. When the eccentric wheel 119 reaches the top, it pushes the filter plate 106 upwards, and the filter plate 106 pulls the first telescopic rod 107 and the first return spring 108 to extend. When the eccentric wheel 119 reaches the bottom, it resets the first telescopic rod 107 and the first return spring 108, and simultaneously resets them. The filter plate 106 can be lowered by pulling it down, and the eccentric wheel 119 can reciprocate to raise and lower the filter plate 106, shaking off the impurities on the filter plate 106. The impurities can roll to the left and out of the device body 1 through the inclined angle of the filter plate 106. The structure of the second rotating rod 110 and the eccentric wheel 119 allows the filter plate 106 to automatically shake off the impurities. This not only reduces manual intervention and improves the automation and efficiency of the system, but also maintains the high efficiency of the filtration process, ensuring that clean water flows back to the water tank 115, thereby improving the water recycling efficiency and reducing resource waste. In use, when the shredded waste falls into the collection box 205, it can press down on the tray 204 by its own weight. The tray 204 then compresses the second telescopic rod 201 and the second return spring 202, causing them to contract. This allows the tray 204 to lower the collection box 205. As the tray 204 descends, the push rod 207 pushes the piston 208 to slide downwards inside the air cylinder 206. When the piston 208 slides, it compresses the air inside the air cylinder 206, allowing the air to enter the first support column 211 through the first air pipe 209 and the second air pipe 210. When the first support column 211 is inside, the second support column 212 can be pushed downward inside the first support column 211 by air pressure, and at the same time, the third return spring 213 is pulled to extend. Then, when the second support column 212 slides, it can push the pressure plate 214 to descend inside the device body 1 to squeeze the waste material, so that the waste material can fit more closely to the crushing roller 103. Through the arrangement of the air cylinder 206 and the pressure plate 214, the waste material can be squeezed, making the waste material fit more tightly to the crushing roller 103, which helps to improve the crushing effect of the waste material, so that the waste material can be crushed more evenly and thoroughly, optimize the waste material processing efficiency, and accelerate the waste material processing process.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
