Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and in particular to a dust-free crushing device for construction waste. Background Art

[0002] Construction equipment refers to various equipment systems installed in buildings to meet the needs of life, production, safety, etc. The dust-free crushing device can be used as a special construction equipment to handle construction waste, improve the resource utilization rate of construction waste, and reduce environmental pollution. At the same time, construction equipment can also cooperate with the dust-free crushing device during the construction process to jointly achieve green treatment of construction waste.

[0003] In the patent document with the published announcement number CN219187057U, a dust-free crushing device for construction waste is provided, which belongs to the field of construction equipment. The dust-free crushing device for construction waste is provided with a crushing tank and an adsorption tank. The crushing tank and the adsorption tank are connected by a connecting pipe. The connecting pipe is arranged on the top of the crushing tank and the adsorption tank. A pump body and a control valve are arranged on the connecting pipe. Construction waste enters the crushing tank from the feed inlet and is crushed in the crushing tank. The dust generated by the crushing is sucked into the adsorption tank by the connecting pipe. Water enters the adsorption tank for dust reduction. The dust settles in the adsorption tank. After sedimentation, the water is recovered from the water recovery pipe, and the sludge is recovered from the sludge recovery pipe. The water recovered by the water recovery pipe can be recycled as water for dust reduction. While achieving the purpose of dust reduction, the water for dust reduction can be recycled. The construction waste crushing operation of the crushing tank and the adsorption tank, and the dust adsorption operation in the adsorption tank are carried out in a closed space, and no dust will be generated.

[0004] The dust generated by the crushing of the above-mentioned device is sucked into the adsorption tank through the connecting pipe, and then dust reduction is achieved by spraying water on the dust floating inside the adsorption tank. After sedimentation, the water is recovered from the water recovery pipe, and the dust is recovered from the sludge recovery pipe. After the implementation of this device, a certain amount of water needs to be sprayed. The water can only be reused after sedimentation and purification, and it is still difficult to ensure the quality of the sedimentation water after sedimentation. When cleaning the precipitated sludge, it can only be flushed out by a large amount of liquid water, which causes a certain waste of water resources and increases the treatment cost.

An inlet 203 is provided on the upper side of the upper protective shell 201, and a feeding mechanism 1 is installed at the inlet 203. A transmission mechanism 8 is installed on the side of the upper shell mechanism 2 away from the feeding mechanism 1. Except for the position of the inlet 203, the inner wall of the upper protective shell 201 is evenly surrounded and fixedly connected with a crushing block 202. An upper discharge port 204 is provided on the lower side of the upper protective shell 201, and an upper discharge mechanism is installed at the upper discharge port 204. 4.

An upper ring plate 603 is fixedly connected to the contact position between the lower protective shell 601 and the upper protective shell 201. A sieve plate 604 is installed in the middle of the upper ring plate 603. A plurality of holes that are interconnected and neatly arranged are provided on the upper and lower surfaces of the sieve plate 604. A supporting leg 7 is fixedly connected to the bottom of the lower protective shell 601.

[0027] Reference Figure 1-3The feeding mechanism 1 includes two feeding side plates 101, which are installed on the side of the upper protective shell 201 close to the feeding port 203. A socket 102 is opened in the middle of the feeding side plate 101, and a plug rod 104 is slidably connected inside the socket 102. A first baffle 103 is limited in the middle of the two feeding side plates 101, and the lower end of the first baffle 103 is movably connected to the lower end of the feeding port 203. First, guide the construction waste into the upper protective shell 201 along the first baffle 103. At this time, the first baffle 103 plays a bearing and guiding role. The two feeding side plates 101 are parallel to the plate body of the first baffle 103 through their bottoms, and play a limiting and supporting role on both sides of the first baffle 103. After the construction waste is transported, push the first baffle 103 to block the feeding port 203, and push the insertion rod 104 to pass through the sockets 102 on the two feeding side plates 101. At this time, the back of the insertion rod 104 is against the back of the first baffle 103, thereby realizing the feeding operation.

[0028] Reference Figure 1-3 The striking mechanism 3 includes a motor 301, which is mounted on the upper surface of the upper protective shell 201. The output end of the motor 301 is fixedly connected to a transmission rod 302, which penetrates through the upper surface of the upper protective shell 201 and is fixedly connected to a plurality of evenly arranged striking plates 303 on the rear side. When the construction waste conveying operation is completed, the motor 301 is started, the motor 301 drives the transmission rod 302 to rotate, and the transmission rod 302 drives the striking plate 303 to rotate. The striking plate 303 continuously stirs and strikes the construction waste during the rotation process, crushing the construction waste into a smaller volume, so that it can pass through the screen plate 604 and fall into the lower protective shell 601, and the construction waste that cannot be crushed is retained above the screen plate 604, thereby achieving the crushing operation.

[0029] Reference Figure 1-3 The upper discharging mechanism 4 includes an upper plate frame 401, which is installed at the upper discharging port 204. The upper plate frame 401 is a prism frame with front and rear openings. The upper end of the upper plate frame 401 is plugged with a second baffle 402.

The second baffle 402 is slidably connected to the inner wall of the upper plate frame 401. After the construction waste is crushed, there will be components such as steel wire and aluminum plate that are not easy to be crushed located above the sieve plate 604. The second baffle 402 is dragged upward, and the second baffle 402 slides along the inner side of the upper plate frame 401, so that the bottom of the second baffle 402 is pulled out from the slot 403. The dragging continues, so that the interior of the upper protective shell 201 is exposed to the upper discharging port 204, and the garbage above the sieve plate 604 is cleaned up through the upper discharging port 204, that is, the garbage above the sieve plate 604 is processed.

[0030] Reference Figure 1-3The lower discharging mechanism 5 includes a lower plate frame 501, which is installed at the lower discharging port 602. The upper plate frame 401 is a prism frame with front and rear openings. The upper end of the lower plate frame 501 is hinged with a third baffle 502, and a fixing opening 503 is provided in the middle of the lower end of the third baffle 502. The fixing opening 503 is rectangular. The front face of the lower end of the lower plate frame 501 is rotatably connected to the corresponding position of the fixing opening 503, and a rectangular mechanism is provided at the front end of the fixing bolt 504. After the garbage above the sieve plate 604 is cleaned, the fixing bolt 504 is rotated so that the rectangular mechanism at the front end of the fixing bolt 504 is horizontally aligned with the fixing opening 503, and the third baffle 502 can be opened to clean the garbage below the sieve plate 604.

[0031] Reference Figure 1-3 The transmission mechanism 8 includes a dust extraction pipe 801, which passes through the upper end of the upper protective shell 201. A protective cage is installed at one end of the dust extraction pipe 801 close to the upper protective shell 201, and an electric fan 802 is installed at one end of the dust extraction pipe 801 away from the upper protective shell 201. A transmission pipe 803 is installed at the bottom of the electric fan 802. The lower end of the transmission pipe 803 is plugged into a dust removal mechanism 9. The dust removal mechanism 9 includes a dust removal cylinder 901. A support leg 902 is provided at the lower end of the dust removal cylinder 901. A filter cloth 903 is installed inside the dust removal cylinder 901. The filter cloth 903 is fixed around the lower end of the transmission pipe 803. The lower end of the transmission pipe 803 passes through the filter cloth 903 and is plugged into the dust removal cylinder 901. The dust removal cylinder 901 is filled with liquid water. During the operation of the striking mechanism 3 and the cleaning of the garbage after crushing, the electric fan 802 has been sucking dust from the inside of the upper protective shell 201. The dust suction principle is the same as that of a vacuum cleaner. The electric fan 802 drives the airflow to move into the dust suction pipe 801, and the transmission mechanism 8 transports the dust to the inside of the dust removal mechanism 9. The dust removal cylinder 901 in the dust removal mechanism 9 carries a large amount of liquid water. The gas containing dust is transported into the water and moves upward in the form of bubbles. After being filtered by the filter cloth 903, the gas is squeezed out of the filter cloth 903, and the solid dust remains on the lower surface of the filter cloth 903, and falls to the bottom of the dust removal cylinder 901 after being rinsed by the stirred water, thereby realizing the transmission and collection of dust.

[0032] Working principle: First, guide the construction waste into the upper protective shell 201 along the first baffle 103. At this time, the first baffle 103 plays a bearing and guiding role. The two feeding side plates 101 play a limiting and supporting role on both sides of the first baffle 103 through their bottoms parallel to the plate body of the first baffle 103. After the construction waste is transported, push the first baffle 103 to block the feed port 203, and push the insertion rod 104 to pass through the sockets 102 on the two feeding side plates 101. At this time, the back of the insertion rod 104 is against the back of the first baffle 103, thereby realizing the feeding operation. When the construction waste transportation operation is completed, start the motor 301, the motor 301 drives the transmission rod 302 to rotate, and the transmission rod 302 drives the striking plate 303 to rotate. The striking plate 303 continuously stirs and strikes the construction waste during the rotation process, and crushes the construction waste into a smaller volume, so that it can pass through the screen plate 604 and fall into the lower protective shell 601. The construction waste that cannot be crushed is retained above the screen plate 604, thereby realizing the crushing operation;

[0033] After the construction waste is crushed, there will be components such as steel wire and aluminum plates that are not easy to be crushed located above the sieve plate 604. Drag the second baffle plate 402 upward, and the second baffle plate 402 slides along the inner side of the upper plate frame 401, so that the bottom of the second baffle plate 402 is pulled out from the inside of the slot 403. Continue to drag, so that the inside of the upper protective shell 201 is exposed at the upper discharge port 204, and the garbage above the sieve plate 604 is cleaned up through the upper discharge port 204, that is, the garbage above the sieve plate 604 is processed. After the garbage above the sieve plate 604 is cleaned up, turn the fixing bolt 504 so that the rectangular mechanism at the front end of the fixing bolt 504 is horizontally aligned with the fixing port 503, and then the third baffle plate 502 can be opened, thereby realizing the cleaning of the garbage below the sieve plate 604;

[0034] During the operation of the striking mechanism 3 and the cleaning of the garbage after crushing, the electric fan 802 has been sucking dust from the inside of the upper protective shell 201. The dust suction principle is the same as that of a vacuum cleaner. The electric fan 802 drives the airflow to move into the dust suction pipe 801, and the transmission mechanism 8 transports the dust to the inside of the dust removal mechanism 9. The dust removal cylinder 901 in the dust removal mechanism 9 carries a large amount of liquid water. The gas containing dust is transported into the water and moves upward in the form of bubbles. After being filtered by the filter cloth 903, the gas is squeezed out of the filter cloth 903, and the solid dust remains on the lower surface of the filter cloth 903, and falls to the bottom of the dust removal cylinder 901 after being rinsed by the stirred water, thereby realizing the transmission and collection of dust.
