Description

Technical Field

[0001] The invention relates to the technical field of construction waste treatment, and in particular to a construction solid waste treatment device. Background Art

[0002] With the acceleration of industrialization and urbanization, the amount of construction solid waste is increasing. Traditional landfill or stacking methods occupy land and pollute the environment. Hammer-type solid waste crushers, as common equipment for processing solid waste such as concrete, bricks and tiles, are widely used in the field of resource recycling of various types of construction solid waste. However, hammer-type solid waste crushers usually adopt a single shaft design, relying on a shaft to drive the breaker to rotate at high speed to achieve the crushing of construction solid waste.

[0003] When a large amount of construction solid waste quickly enters the crushing chamber, the single rotating shaft design cannot effectively disperse and process the construction solid waste load, causing the crusher to easily become blocked. Blockage not only reduces the processing efficiency of the equipment, but may also cause equipment overload and damage, increase maintenance costs and downtime, and affect the resource utilization of construction solid waste. Summary of the invention

[0007] A hollow gear is fixed on the shell, the hollow gear is meshed with the gear, and a screening component is fixed on the discharge port.

[0008] The axis of the first mounting bracket is parallel to the axis of the breaker hammer.

[0009] As a preferred technical solution of the present invention, a cavity is provided in the breaker hammer, and a plurality of impact blocks are placed in the cavity.

[0010] Wherein, on the cross section perpendicular to the axis of the breaker, the outer edge of the cavity is a regular polygon.

[0011] As a preferred technical solution of the present invention, the crushing component includes two crushing hammers, and the support rod is located between the two crushing hammers.

[0012] As a preferred technical solution of the present invention, the outer edge of the cavity is a square or an equilateral triangle.

[0013] As a preferred technical solution of the present invention, a feeding frame is extended outwardly from the feeding port.

[0014] As a preferred technical solution of the present invention, the screening assembly includes a positioning rod, on which a plurality of sliding arc plates are installed, an elastic member is installed between two adjacent arc plates, and both ends of the positioning rod are installed with position-adjustable positioning members.

[0018] As a preferred technical solution of the present invention, the number of crushing components is three.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. In the construction solid waste treatment device exemplified in the present invention, on the one hand, the crushing assembly rotates around the axis of the first mounting frame while the crushing assembly rotates on its own, and multiple crushing assemblies form staggered movement paths in the inner cavity of the shell, thereby increasing the movement of the construction solid waste in the inner cavity of the shell, and the construction solid waste can temporarily stay in the crushing gap, effectively dispersing the crushing load, reducing the risk of blockage, and improving the resource utilization efficiency of the construction solid waste; on the other hand, after the breaker hammer collides with the construction solid waste, the impact received by the breaker hammer causes the breaker hammer and the support rod to move in the opposite direction of the rotation direction, and the impact block collides with the other corner of the cavity, and the impact block reduces the momentum of the breaker hammer, so that the support rod returns to a stable state as soon as possible, thereby increasing the number of collisions between the breaker hammer and the construction solid waste, and improving the crushing efficiency of the equipment for the construction solid waste; on the other hand, after the impact block collides with the inner wall of the cavity, the centrifugal force received by the impact block causes the breaker hammer to rotate, so that the wear of the breaker hammer is uniform at all locations.

[0020] 2. In the construction solid waste treatment device of the example of the present invention, a plurality of sliding arc plates are installed on the positioning rod, and an elastic member is installed between two adjacent arc plates. The positions of the two positioning members on the positioning rod are adjusted, thereby adjusting the distance between the two adjacent arc plates, thereby realizing the adjustment of the screening size of the crushed construction solid waste.

[0021] 3. In the construction solid waste treatment device exemplified in the present invention, the friction between the breaker hammer and the construction solid waste causes the breaker hammer to rotate during the process of crushing the construction solid waste, thereby changing the contact position between the breaker hammer and the construction solid waste, making the wear of the breaker hammer uniform, increasing the service life of the breaker hammer, and reducing the workload of the staff in replacing the breaker hammer.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Embodiment 1: See also Figure 1-7 The present embodiment discloses a construction solid waste treatment device, including a shell 4, a feed port 8 is provided on the top side of the shell 4, a discharge port 7 is provided on the bottom side of the shell 4, a first mounting port and a second mounting port are provided on the outer side of the shell 4, a rotating circular first mounting frame 3 is installed on the first mounting port, a rotating circular second mounting frame 9 is installed on the second mounting port, the axis of the first mounting frame 3 coincides with the axis of the second mounting frame 9, and at least two crushing components 5 are arranged at equal angles around the axis of the first mounting frame 3 between the first mounting frame 3 and the second mounting frame 9.

[0026] The crushing assembly 5 includes a rotating shaft 51, and both ends of the rotating shaft 51 are connected to the first mounting frame 3 and the second mounting frame 9 respectively through bearings. A gear 52 is coaxially fixed to one end of the rotating shaft 51. A plurality of crushing components are installed on the outer side of the rotating shaft 51. The crushing components include a bracket rod 53, one end of the bracket rod 53 is connected to the rotating shaft 51 through a pin shaft or a hinge seat, and a circular breaker 54 is installed on the other end of the bracket rod 53 through a pin shaft or a bearing.

[0027] A hollow gear 2 is fixed on the housing 4 , the hollow gear 2 is meshed with the gear 52 , and a screening assembly 6 is fixed on the discharge port 7 .

[0028] The inner cavity of the shell 4 is circular, and the axis of the inner cavity of the shell 4, the axis of the first mounting bracket 3 and the axis of the breaker 54 are parallel.

[0029] Preferably, the number of the crushing assemblies 5 is three.

[0030] Preferably, the screening component 6 is an arc-shaped screening plate with a plurality of screening holes.

[0031] The working process and principle of this embodiment are: The staff makes the power output shaft of the external motor and the first mounting frame 3 coaxially fixedly connected through the coupling, and the staff makes the external motor drive the first mounting frame 3 to rotate, the hollow gear 2 and the gear 52 are meshed, and the first mounting frame 3 drives the crushing assembly 5 to rotate. The crushing assembly 5 rotates around the axis of the first mounting frame 3 and the crushing assembly 5 rotates on its own. Multiple crushing assemblies 5 form staggered movement paths in the inner cavity of the shell 4, increasing the movement of construction solid waste in the inner cavity of the shell 4, and the construction solid waste can temporarily stay in the crushing gap, effectively dispersing the crushing load and reducing the risk of blockage.

[0032] The breaker hammer 54 is rotatable on the support rod 53. During the process of crushing the construction solid waste by the breaker hammer 54, the friction between the breaker hammer 54 and the construction solid waste causes the breaker hammer 54 to rotate, thereby changing the contact position between the breaker hammer 54 and the construction solid waste, making the wear of the breaker hammer 54 uniform at all locations, increasing the service life of the breaker hammer 54, and reducing the workload of the staff in replacing the breaker hammer 54.

[0033] Furthermore, a feed frame is extended outward from the feed port 8, and the feed frame blocks the construction solid waste splashed out from the feed port 8, thereby improving the safety of the construction solid waste treatment device.

[0034] Embodiment 2: like Figure 6 As shown, this embodiment discloses a construction solid waste treatment device, and its structure is substantially the same as that of the first embodiment, except that a cavity 55 is provided in the breaker hammer 54 of this embodiment, and a plurality of impact blocks 56 are placed in the cavity 55 .

[0035] In a cross section perpendicular to the axis of the breaker 54, the outer edge of the cavity 55 is a regular polygon.

[0036] The working process and principle of this embodiment are: When the breaker hammer 54 does not hit the construction solid waste, the impact block 56 is farthest from the rotating shaft 51, and the impact block 56 is located at a corner of the cavity 55. After the breaker hammer 54 collides with the construction solid waste, the impact on the breaker hammer 54 causes the breaker hammer 54 and the support rod 53 to move in the opposite direction of the rotation direction, and then the impact block 56 collides with the other corner of the cavity 55. The impact block 56 reduces the momentum of the breaker hammer 54, allowing the support rod 53 to return to a stable state as soon as possible, increasing the number of collisions between the impact block 56 and the construction solid waste, and improving the crushing efficiency of the equipment for construction solid waste.

[0037] Furthermore, after the impact block 56 collides with the inner wall of the cavity 55 , the centrifugal force exerted on the impact block 56 causes the breaker hammer 54 to rotate, so that the wear of all parts of the breaker hammer 54 is uniform, and the impact block 56 improves the accuracy of the rotation of the breaker hammer 54 .

[0038] Furthermore, the outer edge of the cavity 55 is a square or an equilateral triangle.

[0039] Furthermore, the ratio of the mass of the impact block 56 in the cavity 55 to the mass of the breaker 54 is 1.0:1.0-2.0, and the impact block 56 and the breaker 54 are both made of metal.

[0040] Embodiment three: like Figure 5 As shown, this embodiment discloses a construction solid waste treatment device, and its structure is substantially the same as that of the second embodiment, except that the crushing component of this embodiment includes two crushing hammers 54, and the support rod 53 is located between the two crushing hammers 54. The two crushing hammers 54 allow the centrifugal force exerted on the crushing component to pass through the support rod 53, thereby improving the safety of the crushing component during operation.

[0042] Furthermore, the elastic member 63 is an elastic rubber tube or a spring, and the positioning member is a clamp, a pin or a bolt.

[0043] The working process and principle of this embodiment are: The staff adjusts the positions of the two positioning rods 62, thereby adjusting the distance between two adjacent arc-shaped plates 61, so as to adjust the screening size of the construction solid waste after crushing.

[0044] Furthermore, the crushing component includes two crushing hammers 54, and the support rod 53 is located between the two crushing hammers 54. During the rotation of the crushing component, the two crushing hammers 54 partially overlap with one of the arc plates 61, and the crushing hammers 54 hit the construction solid waste stuck between two adjacent arc plates 61, thereby improving the screening efficiency of the screening component 6 for construction solid waste.

[0045] Embodiment five: like Figure 2 , Figure 7 As shown, this embodiment discloses a construction solid waste treatment device, and its structure is substantially the same as that of the first embodiment, except that the screening assembly 6 of this embodiment includes a positioning rod 62 , on which a plurality of parallel arc plates 61 are fixed.

[0046] The working process and principle of this embodiment are: The crushed construction solid waste falls through the gap between adjacent arc-shaped plates 61, thereby achieving the screening of the construction solid waste.

[0047] Embodiment six: like Figure 1 , Figure 4 As shown, this embodiment discloses a construction solid waste treatment device, the structure of which is substantially the same as that of the first embodiment, except that this embodiment further includes a drive frame 1, and one end of each rotating shaft 51 is rotatably connected to the drive frame 1.
