Description

Technical Field

[0001] This utility model relates to the field of concrete recycling technology, and in particular to a concrete sand and gravel separation device. Background Technology

[0002] In the recycling of waste concrete, the concrete is first crushed and then screened to separate sand and gravel of different sizes. Existing separation devices lack dust control capabilities, generating significant amounts of dust during screening. This dust disperses into the surrounding air, causing pollution. Therefore, there is an urgent need to develop a concrete sand and gravel separation device that facilitates screening and significantly reduces dust dispersion into the surrounding air through a triple process of dust isolation, dust suppression, and dust filtration. This would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a concrete sand and gravel separation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A concrete aggregate separation device includes a screening box, a box door, a dust collection mechanism, a dust suppression mechanism, a first screen, and a second screen. The top of the screening box has a feed inlet, and an end cap is detachably connected to the feed inlet via threads. The box door is rotatably connected to the screening box via a hinge. Both the first and second screens are fixed inside the screening box, with the first screen positioned above the second screen. Isolation covers are fixed to both the first and second screens, and a vibration motor is installed inside each isolation cover. The dust suppression mechanism includes a water pump, a diversion pipe, and atomizing nozzles. The water pump is fixed to the outside of the screening box, its inlet is connected to an external water source via a pipe, and its outlet is connected to two diversion pipes via pipes. The diversion pipes are fixed inside the screening box, and multiple atomizing nozzles are installed on each diversion pipe. The dust collection mechanism is installed on and connected to the side of the screening box.

[0006] Preferably, a first magnetic strip is fixed to one side of the box door, and a second magnetic strip for attracting the first magnetic strip is fixed to one side of the screening box, with the opposite magnetic poles of the first and second magnetic strips arranged opposite to each other.

[0007] Preferably, the mesh size of the first screen is larger than that of the second screen.

[0008] Preferably, the dust collection mechanism includes: a suction pump, a suction pipe, a filter box, a side plate, and dust filters. The suction pump and the filter box are both fixed to the side of the screening box. The air inlet of the suction pump is connected to the suction pipe, which is inserted into the screening box. The air outlet of the suction pump is inserted into the filter box. The side plate is detachably installed on the side of the filter box by bolts, and multiple dust filters inserted into the filter box are fixed on the side plate.

[0009] Preferably, the bottom of the filter box is provided with an air outlet.

[0010] The beneficial effects of this utility model are as follows: When using this concrete aggregate separation device, the crushed concrete is added through the feed inlet. Then, the end cover is closed and the box door is shut, forming a relatively enclosed area inside the screening box. This reduces dust dispersion during screening. A vibrating motor is started to vibrate the first and second screens, screening aggregates of different sizes. Simultaneously, a water pump delivers water to the distribution pipe, and atomizing nozzles spray water mist to settle the dust in the screening box. After screening, a suction pump is started to transport the remaining dust in the screening box to the filter box, where it is filtered multiple times through multiple dust filters. The filtered air is discharged through the air outlet, reducing dust pollution to the outside environment. Finally, the box door is opened to remove the screened concrete aggregates. In summary, this utility model facilitates concrete aggregate screening, and through the triple action of dust isolation, dust suppression, and dust filtration, it greatly reduces dust dispersion into the surrounding air, thus reducing air pollution.

[0021] See Figures 1-6In this embodiment of the present invention, a concrete aggregate separation device includes a screening box 1, a box door 2, a dust collection mechanism 4, a dust suppression mechanism 5, a first screen 6, and a second screen 7. The top of the screening box 1 is provided with a feed inlet 101, and an end cap 102 is detachably connected to the feed inlet 101 via threads. The box door 2 is rotatably connected to the screening box 1 via a hinge. A first magnetic strip 201 is fixed to one side of the box door 2, and a second magnetic strip 3 for attracting the first magnetic strip 201 is fixed to one side of the screening box 1. The first magnetic strip 201 and the second magnetic strip 3... The magnetic poles of opposite polarities are arranged oppositely. The first screen 6 and the second screen 7 are both fixed inside the screening box 1, with the first screen 6 positioned above the second screen 7. The mesh size of the first screen 6 is larger than that of the second screen 7. The first screen 6 and the second screen 7 separate concrete aggregates of different sizes. Each of the first screen 6 and the second screen 7 is fixed with an isolation cover 8. A vibrating motor 9 is installed inside each isolation cover 8. The wires of the vibrating motor 9 (not shown in the figure) extend to the outside of the screening box 1. The isolation cover 8 isolates the vibrating motor 9, reducing the impact of magnetic fields. To prevent contact with dust and water mist, the dust suppression mechanism 5 includes a water pump 501, a diversion pipe 502, and an atomizing nozzle 503. The water pump 501 is fixed to the outside of the screening box 1. The inlet of the water pump 501 is connected to an external water source through a pipe, and the outlet of the water pump 501 is connected to two diversion pipes 502 through pipes. The diversion pipes 502 are fixed inside the screening box 1, and each diversion pipe 502 is equipped with multiple atomizing nozzles 503. The dust collection mechanism 4 is installed on and connected to the side of the screening box 1. The dust collection mechanism 4 includes a suction pump 401, a suction nozzle 502, and a suction nozzle 503. Air pipe 402, filter box 403, side plate 404 and dust filter 405, suction pump 401 and filter box 403 are all fixed to the side of screening box 1.

[0023] Working principle: When using this concrete sand and gravel separation device, the crushed concrete is added through the feed inlet 101. Then, the end cover 102 is closed and the box door 2 is shut, thus forming a relatively closed area inside the screening box 1, reducing dust dispersion during screening. The vibration motor 9 is started to vibrate the first screen 6 and the second screen 7, screening sand and gravel aggregates of different sizes under the action of vibration. At the same time, water is pumped by the water pump 501 to the diversion pipe 502, and the atomizing nozzle 503 sprays water mist to settle the dust in the screening box 1. After screening, the suction pump 401 is started to transport the remaining dust in the screening box 1 to the filter box 403. The dust is filtered multiple times through multiple dust filters 405. The filtered air is discharged from the air outlet 4031, thereby reducing dust pollution to the outside world. Finally, the screened concrete sand and gravel aggregates can be removed by opening the box door 2.
