Description

Technical Field

[0001] This utility model relates to the field of construction waste sand making technology, specifically a dry sand making device for the resource utilization of construction waste. Background Technology

[0002] Utility model application CN202221792743.3 discloses a dry sand-making device for the resource utilization of construction waste. By installing a dust suppression cylinder on the right side of the discharge hopper, with multiple levels of dust-proof netting of varying mesh sizes inside, dust is blown into the dust suppression cylinder by fan blades and undergoes layer-by-layer filtration to achieve final dust suppression. This reduces secondary pollution to the environment caused by dust generated during construction waste crushing and improves the working environment for construction waste sand making.

[0003] The aforementioned device filters dust through a dustproof net. After prolonged use, dust and impurities can easily accumulate on the dustproof net, causing blockage of the filter holes and affecting the filtration effect. Manual cleaning of the dustproof net is required, which is time-consuming, labor-intensive, and physically demanding. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a dry sand-making device for the resource utilization of construction waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dry sand-making device for the resource utilization of construction waste includes:

[0007] Construction waste sand making machine;

[0008] Feed hopper, used for feeding construction waste;

[0009] The negative pressure exhaust duct is connected to three connecting pipes, which are respectively connected to the feed hopper, the crushing chamber of the construction waste sand making machine and the discharge port of the construction waste sand making machine.

[0010] A dust suppression component is used to treat dust. The dust suppression component is located on one side of the construction waste sand making machine, and the negative pressure exhaust pipe is connected to the dust suppression component.

[0011] Dust is filtered by dust suppression components to prevent environmental pollution, protect the health of staff, and ensure the normal operation of equipment.

[0012] Furthermore, the dust suppression assembly includes a dust suppression cylinder with a fixed base installed at the bottom. The end of the negative pressure exhaust pipe is connected to one side below the dust suppression cylinder. Three fixed rings are installed on the inner wall of the dust suppression cylinder, and three dustproof nets are provided inside the dust suppression cylinder. The three dustproof nets are respectively located above the three fixed rings. Vibration springs are connected between the fixed rings and the dustproof nets. A bracket is fixedly installed at the rear end of the dust suppression cylinder, and an electrostatic generator is installed on the bracket. The electrostatic generator is connected to the three dustproof nets respectively.

[0013] Furthermore, the dust suppression assembly also includes an arc-shaped connecting plate, which is fixedly connected to the bottom of the dustproof net. A rotating rod is rotatably connected inside the dust suppression cylinder via a bearing seat. Three rotating rods are provided and are respectively located below the three dustproof nets. An eccentric wheel is fixedly connected to each rotating rod, and the eccentric wheel is located below the arc-shaped connecting plate. One end of the rotating rod extends through the dust suppression cylinder. A drive sprocket is fixedly connected to the middle rotating rod, and driven sprockets are fixedly connected to the upper and lower rotating rods. The driven sprockets are connected to the drive sprocket via a chain. A rotating handle is fixedly connected to the middle rotating rod.

[0014] Furthermore, the dust collection cylinder is equipped with a guide plate, and a dust discharge pipe is connected to one side of the dust collection cylinder, with a valve on the dust discharge pipe.

[0015] The dust falls onto the guide plate, which causes the dust to slide towards the ash discharge pipe. The valve is then opened, and the dust in the dust collection cylinder is discharged through the ash discharge pipe.

[0016] Furthermore, the dustproof net is circular and fits against the inner wall of the dust collection cylinder. The three dustproof nets are arranged from top to bottom, and the mesh count of the three dustproof nets increases sequentially from bottom to top.

[0017] Furthermore, a reinforcing rod is fixedly connected to the side wall of the dust collection cylinder, and one end of the reinforcing rod is fixedly connected to the negative pressure exhaust pipe.

[0018] By reinforcing the connecting rods to support and fix the negative pressure exhaust duct, bending deformation of the duct is prevented, thus improving its service life.

[0019] Compared with existing technologies, this technical solution has the following beneficial effects:

[0020] 1. Dust is filtered through three dust screens from bottom to top. The mesh count of the three dust screens increases from bottom to top. The higher the mesh count, the finer the mesh, and the smaller the particles that can be blocked. An electrostatic generator generates static electricity on the three dust screens, which attracts the dust to the screens. Through the three layers of dust screen filtration, dust pollution is prevented, improving the working environment, protecting the health of the staff, and avoiding interference with the normal operation of the equipment.

[0021] 2. The eccentric wheel rotates and contacts the bottom of the arc-shaped connecting plate, which lifts the dust screen upwards. The vibration spring causes the dust screen to vibrate up and down, shaking off the dust covering it. This prevents dust from clogging the filter holes and affecting the filtration effect, making it easier to clean the dust screen and reducing manual labor intensity. Attached Figure Description

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] This utility model provides, for example Figure 1-4 The dry sand making device for the resource utilization of construction waste shown includes:

[0030] Construction waste sand making machine 1;

[0031] Feed hopper 2 is used for feeding construction waste;

[0032] The negative pressure exhaust pipe 3 is connected to three connecting pipes 4, which are respectively connected to the feed hopper 2, the crushing chamber of the construction waste sand making machine 1 and the discharge port of the construction waste sand making machine 1.

[0033] Dust suppression component 5 is used to treat dust. Dust suppression component 5 is located on one side of construction waste sand making machine 1. Negative pressure exhaust pipe 3 is connected to dust suppression component 5.

[0034] Construction waste is poured into the construction waste sand making machine 1 through the feed hopper 2. The construction waste sand making machine 1 processes the construction waste into sand. At the same time, the negative pressure exhaust pipe 3 starts to work, generating negative pressure in the negative pressure exhaust pipe 3. The negative pressure is drawn into the negative pressure exhaust pipe 3 through the connecting pipe 4 from the feed hopper 2, the crushing chamber of the construction waste sand making machine 1 and the discharge port of the construction waste sand making machine 1. The dust is transported to the dust suppression component 5 through the negative pressure exhaust pipe 3. The dust suppression component 5 filters the dust to prevent dust from causing environmental pollution, to avoid affecting the health of the staff and to avoid affecting the normal operation of the equipment.

[0035] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2The dust collection assembly 5 includes a dust collection cylinder 6, a fixed base 7 installed at the bottom of the dust collection cylinder 6, the end of the negative pressure exhaust pipe 3 connected to one side below the dust collection cylinder 6, three fixed rings 8 installed on the inner wall of the dust collection cylinder 6, three dustproof nets 9 provided inside the dust collection cylinder 6, the three dustproof nets 9 are respectively located above the three fixed rings 8, a vibration spring 10 is connected between the fixed rings 8 and the dustproof nets 9, a bracket 11 is fixedly installed at the rear end of the dust collection cylinder 6, an electrostatic generator 12 is installed on the bracket 11, the electrostatic generator 12 is respectively connected to the three dustproof nets 9, the dustproof nets 9 are circular and fit against the inner wall of the dust collection cylinder 6, the three dustproof nets 9 are arranged from top to bottom, and the mesh number of the three dustproof nets 9 increases sequentially from bottom to top.

[0036] Dust generated during the operation of the construction waste sand making machine 1 is transported to the dust settling cylinder 6 through the connecting pipe 4 and the negative pressure exhaust pipe 3. The dust floats upward in the dust settling cylinder 6 and passes through three dustproof nets 9 from bottom to top. The mesh count of the three dustproof nets 9 increases from bottom to top. The higher the mesh count of the dustproof net 9, the finer the mesh and the smaller the particles it can block. At the same time, the electrostatic generator 12 starts working, generating static electricity on the three dustproof nets 9. The static electricity attracts the dust to the dustproof nets 9. After being filtered layer by layer by the three dustproof nets 9, dust pollution is avoided, the working environment is improved, the health of the staff is protected, and the normal operation of the equipment is prevented.

[0037] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The dust suppression assembly 5 also includes an arc-shaped connecting plate 13, which is fixedly connected to the bottom of the dustproof net 9. A rotating rod 14 is rotatably connected inside the dust suppression cylinder 6 via a bearing seat. There are three rotating rods 14, each located below one of the three dustproof nets 9. An eccentric wheel 15 is fixedly connected to the rotating rod 14, which is located below the arc-shaped connecting plate 13. One end of the rotating rod 14 extends through the dust suppression cylinder 6. A drive sprocket 16 is fixedly connected to the middle rotating rod 14. Driven sprockets 17 are fixedly connected to the upper and lower rotating rods 14. The driven sprockets 17 are connected to the drive sprocket 16 via a chain 18. A rotating handle 19 is fixedly connected to the middle rotating rod 14.

[0038] When it is necessary to clean the dust on the dustproof net 9, the operator rotates the middle rotating rod 14 by turning the handle 19. The middle rotating rod 14 drives the upper and lower rotating rods 14 to rotate through the driving sprocket 16, chain 18 and driven sprocket 17. The three rotating rods 14 simultaneously drive the eccentric wheel 15 to rotate. The eccentric wheel 15 rotates and contacts the bottom of the arc-shaped connecting plate 13. The arc-shaped connecting plate 13 lifts the dustproof net 9 upward. The vibration spring 10 makes the dustproof net 9 vibrate up and down. The vibration shakes off the dust covering the dustproof net 9, avoiding the dust from clogging the filter holes of the dustproof net 9 and affecting the filtration effect. This makes it easier to clean the dust on the dustproof net 9 and reduces the intensity of manual labor.

[0039] Refer to the instruction manual appendix Figure 1 The dust collection cylinder 6 is equipped with a guide inclined plate 20, and a dust discharge pipe 21 is connected to one side of the dust collection cylinder 6. A valve 22 is installed on the dust discharge pipe 21.

[0040] The mesh count of the three dust screens 9 increases sequentially from bottom to top. The filter holes of the lower dust screen 9 are larger than those of the upper dust screen 9. Dust and impurities on the upper dust screen 9 can pass through the lower dust screen 9 and fall onto the guide plate 20. The guide plate 20 causes the dust to slide towards the ash discharge pipe 21. The valve 22 is opened, and the dust in the dust collection cylinder 6 is discharged through the ash discharge pipe 21.

[0041] Refer to the instruction manual appendix Figure 4 A reinforcing rod 23 is fixedly connected to the side wall of the dust collection cylinder 6, and one end of the reinforcing rod 23 is fixedly connected to the negative pressure exhaust pipe 3.

[0042] By reinforcing the connecting rod 23 to support and fix the negative pressure exhaust pipe 3, bending deformation of the negative pressure exhaust pipe 3 is avoided, thus improving its service life.
