Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, specifically a construction waste treatment device. Background Technology

[0002] Construction generates a large amount of waste materials, such as large pieces of waste concrete, waste bricks, marble, etc. These wastes include powder materials as well as some blocky materials, which limits the recycling and reuse of construction waste. Large hammer crushers or crushers can be used to crush the waste to the size that can be crushed by a pulverizer. Then, a stone crusher can be used to crush the waste into the gravel, sand, etc. required for construction. Finally, the mixture can be separated and recycled using screening equipment.

[0003] For example, patent application number CN202322659639.8 discloses a construction waste screening machine, including a shell with an inlet and an outlet at the top and bottom. Several screens are arranged longitudinally at intervals inside the shell, with the mesh size of the screens gradually decreasing from top to bottom. The screens are hinged to the inner wall of the shell via a rotating shaft. A rotary drive component is provided on the inner wall of the shell to drive the screens to rotate. Several discharge components are arranged vertically at intervals on the side wall of the shell. When the end of the screen away from the rotary drive component rotates downward at a certain angle, the screen connects with the discharge component, and the construction waste moves from the screen to the discharge component and is discharged from the shell, thereby reducing the probability of construction waste accumulating on the screen and increasing the screening efficiency.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of not being able to process construction waste on the first and second screening screens during the discharge process, requiring the machine to be stopped first and the discharge window opened to clean the construction waste on the first and second screening screens, the construction waste on the first and second screening screens accumulates as the machine runs, which affects the efficiency of the first and second screening screens in screening construction waste.

[0005] However, during the screening of construction waste, a large amount of dust is generated, which leaks into the surrounding environment, pollutes the air, and can be inhaled by operators, posing a threat to their health. Utility Model Content

This device solves the problem that a large amount of dust is generated during the screening process of construction waste, causing the dust to leak into the surrounding environment, pollute the air, and be inhaled by operators, thus harming their health.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a construction waste treatment device, comprising a screening machine, a discharge port, and a feeding hopper. The bottom of the feeding hopper is fixedly connected to the left side of the top of the screening machine, and the feeding hopper is connected to the screening machine. The discharge port is located at the top and bottom of the left side of the screening machine. A water pump is fixedly connected to the right side of the screening machine. A water inlet is fixedly connected to the top of the right side of the inner wall of the screening machine. An atomizing nozzle is threadedly connected to the left side of the water inlet. The output end of the water pump is connected to the water inlet. A filter plate is provided at the bottom of the right side of the inner wall of the screening machine. Anti-clogging mechanisms are fixedly connected to the front and rear sides of the top of the filter plate. Limiting components are fixedly connected to the front and rear sides of the top of the right side of the filter plate.

[0008] In a preferred embodiment of this invention, the anti-clogging mechanism includes a transmission rod, the bottom of which is fixedly connected to the front and rear sides of the top of the filter plate. Scraper strips are provided on both sides of the left side of the filter plate, the right side of which contacts the left side of the filter plate. The front and rear sides of the scraper strips are fixedly connected to the bottom of the front and rear right sides of the inner wall of the screening machine. A spring is fixedly connected to the right side of the bottom of the filter plate, and several springs are provided and are evenly distributed.

[0009] In a preferred embodiment of this utility model, the limiting component includes a limiting block. The left side of the limiting block is fixedly connected to the front and rear sides of the top right side of the filter plate. Limiting grooves are provided at the bottom of the front and rear sides of the right side of the inner wall of the screening machine. The inner wall of the limiting groove is slidably connected to the surface of the limiting block.

[0010] As a preferred embodiment of this utility model, a rubber sealing strip is fixedly connected to the left side of the bottom of the filter plate, and the bottom of the rubber sealing strip is fixedly connected to the right side of the bottom of the inner wall of the screening machine.

[0011] As a preferred embodiment of this utility model, rubber sealing plates are fixedly connected to both the front and rear sides of the top right side of the filter plate, and the right side of the rubber sealing plate is movably connected to the right side of the inner wall of the screening machine.

[0012] As a preferred embodiment of this utility model, a cleaning port is provided at the bottom of the front side of the screening machine, and a sealing plate is movably connected inside the cleaning port. The sealing plate is fixedly connected to the screening machine by bolts.

[0013] As a preferred embodiment of this utility model, the inner wall of the cleaning port is provided with a sealing groove, and a sealing ring is embedded inside the sealing groove, and the sealing ring is sleeved on the surface of the sealing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a water pump, draws out the water stored in the lowest space inside the screening machine and transmits it through the water inlet to the atomizing nozzle for spraying. The atomizing nozzle sprays out a large amount of water mist, which adsorbs the large amount of dust generated during the screening process. This solves the problem that a large amount of dust is generated during the screening of construction waste, causing the dust to leak into the surrounding environment, pollute the air, and be inhaled by the operators, posing a health hazard. This achieves the effect of auxiliary dust removal.

[0016] 2. This utility model, by setting an anti-clogging mechanism, utilizes the spring force to lift the filter plate during use, causing the transmission rod at the top of the filter plate to contact the screening plate inside the screening machine. As the screening machine starts and vibrates the screening plate inside, the screening machine simultaneously drives the transmission rod to vibrate continuously, causing the filter plate to shake. The spring further increases the shaking frequency during this process. This shaking dislodges impurities from the filter plate, preventing clogging and ensuring efficient water pumping. Simultaneously, the shaking of the filter plate creates relative movement with the scraper, causing the scraper to continuously scrape the left side of the filter plate, further enhancing the anti-clogging effect.

[0017] 3. By setting a limiting component, the filter plate will drive the limiting block to shake synchronously during the shaking process. At this time, the limiting block and the limiting groove can be used to limit the filter plate in front, back, left and right, so as to avoid the filter plate shaking in a chaotic direction and thus the anti-clogging effect is not good.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, the present invention provides a construction waste treatment device, including a screening machine 1, a discharge port 2 and a feeding hopper 3. The bottom of the feeding hopper 3 is fixedly connected to the left side of the top of the screening machine 1, and the feeding hopper 3 is connected to the screening machine 1. The discharge port 2 is opened at the top and bottom of the left side of the screening machine 1. A water pump 4 is fixedly connected to the right side of the screening machine 1. A water inlet 5 is fixedly connected to the top of the right side of the inner wall of the screening machine 1. An atomizing nozzle 6 is threadedly connected to the left side of the water inlet 5. The output end of the water pump 4 is connected to the water inlet 5. A filter plate 7 is provided at the bottom of the right side of the inner wall of the screening machine 1. Anti-blocking mechanisms 8 are fixedly connected to the front and rear sides of the top of the filter plate 7. Limiting components 9 are fixedly connected to the front and rear sides of the top of the right side of the filter plate 7.

[0025] refer to Figure 4 The anti-clogging mechanism 8 includes a transmission rod 81. The bottom of the transmission rod 81 is fixedly connected to the front and rear sides of the top of the filter plate 7. Scraper strips 82 are provided on both sides of the left side of the filter plate 7. The right side of the scraper strips 82 is in contact with the left side of the filter plate 7. The front and rear sides of the scraper strips 82 are fixedly connected to the bottom of the front and rear right sides of the inner wall of the screening machine 1. A spring 83 is fixedly connected to the right side of the bottom of the filter plate 7. Several springs 83 are provided and are evenly distributed.

[0026] As a technical optimization of this utility model, by setting an anti-clogging mechanism 8, during the use of the filter plate 7, the elastic force of the spring 83 can lift the filter plate 7 upward, so that the transmission rod 81 at the top of the filter plate 7 contacts the screening plate inside the screening machine 1. During the screening process, the screening machine 1 drives the screening plate inside the screening machine 1 to vibrate and screen. The screening machine 1 will synchronously drive the transmission rod 81 to vibrate continuously, so that the filter plate 7 will shake continuously. During the shaking process, the spring 83 can also increase the shaking frequency of the filter plate 7. The shaking of the filter plate 7 can shake off the impurities filtered on the filter plate 7, avoiding the filter plate 7 from clogging and affecting the water pump 4 pumping efficiency. At the same time, the shaking of the filter plate 7 will generate relative movement with the scraper 82, so that the scraper 82 will continuously scrape the left side of the filter plate 7, further improving the anti-clogging effect.

[0027] refer to Figure 4 The limiting component 9 includes a limiting block 91. The left side of the limiting block 91 is fixedly connected to the front and rear sides of the top right side of the filter plate 7. Limiting grooves 92 are opened at the bottom of the front and rear sides of the right side of the inner wall of the screening machine 1. The inner wall of the limiting groove 92 is slidably connected to the surface of the limiting block 91.

[0028] As a technical optimization of this utility model, by setting a limiting component 9, during the shaking process of the filter plate 7, the filter plate 7 will synchronously drive the limiting block 91 to shake. At this time, the sliding cooperation between the limiting block 91 and the limiting groove 92 can limit the filter plate 7 in the front, back, left and right directions, so as to avoid the filter plate 7 from being confused in direction during the shaking process, resulting in poor anti-clogging effect.

[0029] refer to Figure 4 A rubber sealing strip 10 is fixedly connected to the left side of the bottom of the filter plate 7, and the bottom of the rubber sealing strip 10 is fixedly connected to the right side of the bottom of the inner wall of the screening machine 1.

[0030] As a technical optimization of this utility model, by setting a rubber sealing strip 10, during the process of the filter plate 7 continuously shaking to prevent clogging, the rubber sealing strip 10 can seal the gap between the filter plate 7 and the bottom of the inner wall of the screening machine 1, thereby avoiding the situation where there is a gap between the filter plate 7 and the bottom of the inner wall of the screening machine 1, which would lead to poor filtration effect.

[0031] refer to Figure 4 A rubber sealing plate 11 is fixedly connected to both the front and rear sides of the top right side of the filter plate 7, and the right side of the rubber sealing plate 11 is movably connected to the right side of the inner wall of the screening machine 1.

[0032] As a technical optimization of this utility model, by setting a rubber sealing plate 11, the rubber sealing plate 11 can be driven to shake up and down synchronously during the continuous up and down shaking of the filter plate 7. At this time, the rubber sealing plate 11 can seal the limiting groove 92 that was originally leaked when the filter plate 7 was shaking, so as to prevent particles in the sewage from entering the limiting groove 92 and affecting the sliding cooperation between the limiting groove 92 and the limiting block 91.

[0033] Referring to Figure 2, a cleaning port 12 is provided at the bottom of the front of the screening machine 1. A sealing plate 13 is movably connected inside the cleaning port 12. The sealing plate 13 is fixedly connected to the screening machine 1 by bolts.

[0034] As a technical optimization of this utility model, by setting up a cleaning port 12 and a sealing plate 13, when a large amount of filter material exists in the water storage space at the bottom inside the screening machine 1 after long-term use, the user can loosen the bolts on the sealing plate 13 and remove the sealing plate 13 to allow the cleaning port 12 to leak out, so that the user can clean out the large amount of filter material.

[0035] refer to Figure 2 The inner wall of the cleaning port 12 is provided with a sealing groove 14, and a sealing ring 15 is embedded inside the sealing groove 14. The sealing ring 15 is sleeved on the surface of the sealing plate 13.

[0036] As a technical optimization of this utility model, by setting a sealing groove 14 and a sealing ring 15, when the user inserts the sealing plate 13 into the cleaning port 12 and connects it to the screening machine 1 with bolts, the sealing plate 13 will simultaneously drive the sealing ring 15 to be embedded into the interior of the sealing groove 14. The cooperation between the sealing ring 15 and the sealing groove 14 can improve the sealing effect of the sealing plate 13 after installation and prevent water leakage.

[0037] The working principle and usage process of this utility model are as follows: Before use, water is stored in the lowest space inside the screening machine 1. During the process of the screening machine 1 vibrating and screening construction waste, the water pump 4 is started, which draws out the water stored in the lowest space inside the screening machine 1 and transmits it through the water inlet 5 to the atomizing nozzle 6 for spraying. The atomizing nozzle 6 sprays a large amount of water mist into the interior of the screening machine 1, so that the large amount of dust generated during screening is adsorbed by the water mist, thereby preventing the dust from floating in the air and achieving the effect of dust removal. This can be done when the user needs it. When cleaning the screening plates inside the screening machine 1, the atomizing nozzle 6 can be rotated to separate it from the water inlet 5, and the high-pressure nozzle can be connected to the water inlet 5. This allows for cleaning of the inside of the screening machine 1 using the high-pressure nozzle. The wastewater from cleaning or dust removal flows back to the lowest space inside the screening machine 1 for recycling. When this wastewater is pumped out by the water pump 4, it passes through the filter plate 7 to filter out larger particles, ensuring that the sprayed water is clean enough and does not contaminate the inside of the screening machine 1. During operation, the spring force of spring 83 lifts the filter plate 7 upwards, causing the transmission rod 81 at the top of the filter plate 7 to contact the screening plate inside the screening machine 1. This activates the screening machine 1, causing the screening plate inside to vibrate and perform screening. Simultaneously, the screening machine 1 drives the transmission rod 81 to vibrate continuously, causing the filter plate 7 to shake continuously. The spring 83 further increases the shaking frequency during this process, effectively shaking off the impurities filtered from the filter plate 7. To prevent the filter plate 7 from becoming clogged and thus affecting the pumping efficiency of the water pump 4, the vibration of the filter plate 7 will cause relative movement with the scraper 82, causing the scraper 82 to continuously scrape the left side of the filter plate 7, further improving the anti-clogging effect. During the vibration of the filter plate 7, the filter plate 7 will simultaneously drive the limiting block 91 to vibrate. At this time, the sliding cooperation between the limiting block 91 and the limiting groove 92 can limit the filter plate 7 in all directions, preventing the filter plate 7 from becoming chaotic during vibration and thus resulting in poor anti-clogging effect.

[0038] In summary, this construction waste treatment device, by setting up a water pump 4, draws water stored in the lowest space inside the screening machine 1 and transmits it through the water inlet 5 to the atomizing nozzle 6 for spraying. The atomizing nozzle 6 sprays a large amount of water mist, which adsorbs the large amount of dust generated during the screening process of the screening machine 1. This solves the problem that a large amount of dust is generated during the screening of construction waste, which leads to the leakage of dust into the surrounding environment, polluting the air, and being inhaled by operators, causing harm to their health.
