Description

Technical Field

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

[0002] With the acceleration of industrialization and urbanization, the amount of construction solid waste generated is increasing day by day. Traditional landfill or dumping methods occupy land and pollute the environment. Hammer impact solid waste crushers are common equipment for processing solid waste such as concrete, bricks, tiles and ceramic tiles. They are widely used in the field of resource recycling of various construction solid wastes. However, hammer impact solid waste crushers usually adopt a single shaft design, relying on a single shaft to drive the crushing hammer to rotate at high speed in order to crush construction solid waste.

[0003] When a large amount of construction solid waste enters the crushing chamber rapidly, the single shaft design cannot effectively distribute and process the construction solid waste load, which makes the crusher prone to material blockage. Material blockage not only reduces the processing efficiency of the equipment, but may also lead to overload and damage of the equipment, increase maintenance costs and downtime, and affect the resource utilization of construction solid waste. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a construction solid waste treatment device in which multiple crushing components form an interlaced movement path in the inner cavity of the shell, increasing the movement of construction solid waste in the inner cavity of the shell, and construction solid waste can temporarily stay in the crushing gap, effectively dispersing the crushing load, reducing the risk of material blockage, and improving the resource utilization efficiency of construction solid waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction solid waste treatment device, comprising a shell, an inlet on the top side of the shell, an outlet on the bottom side of the shell, a first mounting port and a second mounting port on the outer side of the shell, a rotating circular first mounting frame mounted on the first mounting port, a rotating circular second mounting frame mounted on the second mounting port, and at least two crushing components arranged at equal angles around the axis of the first mounting frame between the first mounting frame and the second mounting frame.

[0006] The crushing assembly includes a rotating shaft, with its two ends rotatably connected to a first mounting bracket and a second mounting bracket, respectively. A gear is coaxially fixed to one end of the rotating shaft, and several crushing components are mounted on the outside of the rotating shaft. Each crushing component includes a support rod, with one end of the support rod rotatably connected to the rotating shaft and the other end of the support rod mounted with a rotating circular crushing hammer.

[0007] A hollow gear is fixed on the housing, and the hollow gear meshes with the gear. 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 embodiment of the present invention, the breaker hammer is provided with a cavity, and a plurality of impact blocks are placed in the cavity.

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

[0011] As a preferred embodiment 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 embodiment of the present invention, the outer edge of the cavity is a square or an equilateral triangle.

[0013] As a preferred embodiment of the present invention, the feed inlet extends outward with a feed frame.

[0014] As a preferred embodiment of the present invention, the screening assembly includes a positioning rod, on which a plurality of sliding arc-shaped plates are mounted, and an elastic element is installed between two adjacent arc-shaped plates. Both ends of the positioning rod are equipped with position-adjustable positioning elements.

[0015] In a preferred embodiment of the present invention, the elastic element is an elastic rubber tube or a spring.

[0016] As a preferred embodiment of the present invention, the screening assembly includes a positioning rod, on which a plurality of parallel arc-shaped plates are fixed.

[0017] As a preferred embodiment of the present invention, it further includes a drive frame, with one end of each rotating shaft being rotatably connected to the drive frame.

[0018] In a preferred embodiment of the present invention, the number of crushing components is three.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The construction solid waste treatment device of the present invention, on the one hand, while the crushing component rotates around the axis of the first mounting frame, the crushing component rotates on its own axis, and multiple crushing components form an interlaced motion path in the inner cavity of the shell, increasing the movement of 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 material blockage, and improving the resource utilization efficiency of construction solid waste; on the other hand, after the breaker hammer collides with the construction solid waste, the impact on the breaker hammer causes the breaker hammer and the support rod to move in the opposite direction of rotation, and the impact block collides with the other corner of the cavity, the impact block reduces the momentum of the breaker hammer, so that the support rod can quickly return to a stable state, increasing the number of impacts between the breaker hammer and the construction solid waste, and improving the crushing efficiency of the equipment for construction solid waste; furthermore, after the impact block collides with the inner wall of the cavity, the centrifugal force on the impact block causes the breaker hammer to rotate, so that the wear of the breaker hammer is uniform throughout.

[0021] 2. In the construction solid waste treatment device of the present invention, a plurality of sliding arc-shaped plates are installed on the positioning rod, and an elastic element is installed between two adjacent arc-shaped plates. By adjusting the position of two positioning elements on the positioning rod, the distance between two adjacent arc-shaped plates is adjusted, thereby realizing the adjustment of the screening size of the crushed construction solid waste.

[0022] 3. In the construction solid waste treatment device of the present invention, the friction between the breaker and the construction solid waste during the crushing process causes the breaker to rotate, changing the contact position between the breaker and the construction solid waste, so that the wear of the breaker is uniform throughout, increasing the service life of the breaker and reducing the workload of workers in replacing the breaker.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see Figure 1-7 This embodiment discloses a construction solid waste treatment device, including a shell 4. The top side of the shell 4 has a feed inlet 8, the bottom side of the shell 4 has a discharge outlet 7, and the outer side of the shell 4 has a first mounting port and a second mounting port. A rotating circular first mounting frame 3 is installed on the first mounting port, and a rotating circular second mounting frame 9 is installed on the second mounting port. The axis of the first mounting frame 3 and the axis of the second mounting frame 9 coincide. At least two crushing components 5 are provided between the first mounting frame 3 and the second mounting frame 9, which are arranged at equal angles around the axis of the first mounting frame 3.

[0034] The crushing assembly 5 includes a rotating shaft 51. Both ends of the rotating shaft 51 are connected to the first mounting bracket 3 and the second mounting bracket 9 respectively via bearings. A gear 52 is coaxially fixed at one end of the rotating shaft 51. Several crushing components are installed on the outside of the rotating shaft 51. Each crushing component includes a support rod 53. One end of the support rod 53 is connected to the rotating shaft 51 via a pin or a hinge seat. A circular breaker hammer 54 is installed at the other end of the support rod 53 via a pin or a bearing.

[0035] A hollow gear 2 is fixed on the housing 4, and the hollow gear 2 meshes with the gear 52. A screening component 6 is fixed on the discharge port 7.

[0036] The inner cavity of the housing 4 is circular, and the axis of the inner cavity of the housing 4, the axis of the first mounting bracket 3, and the axis of the breaker 54 are parallel.

[0037] Preferably, the number of crushing components 5 is three.

[0038] Preferably, the screening component 6 is an arc-shaped screen plate with a plurality of screen holes.

[0039] The working process and principle of this embodiment are as follows:

[0040] The operator fixes the power output shaft of the external motor and the first mounting frame 3 coaxially via a coupling. The operator then drives the external motor to rotate the first mounting frame 3, causing the hollow gear 2 and gear 52 to mesh. The first mounting frame 3 drives the crushing component 5 to rotate. While the crushing component 5 rotates around the axis of the first mounting frame 3, the crushing component 5 also rotates on its own axis. Multiple crushing components 5 form staggered motion paths in the inner cavity of the housing 4, increasing the movement of construction solid waste in the inner cavity of the housing 4. Furthermore, the construction solid waste can temporarily stay in the crushing gap, effectively dispersing the crushing load and reducing the risk of material blockage.

[0041] The hydraulic breaker 54 can rotate on the support rod 53. During the crushing of construction solid waste, the friction between the hydraulic breaker 54 and the construction solid waste causes the hydraulic breaker 54 to rotate, changing the contact position between the hydraulic breaker 54 and the construction solid waste, making the wear of the hydraulic breaker 54 uniform, increasing the service life of the hydraulic breaker 54, and reducing the workload of the staff in replacing the hydraulic breaker 54.

[0042] Furthermore, a feeding frame extends outward from the feed inlet 8, which blocks construction waste splashed out from the feed inlet 8, thereby improving the safety of this construction waste treatment device.

[0043] Example 2:

[0044] like Figure 6 As shown, this embodiment discloses a construction solid waste treatment device, whose structure is roughly the same as that of Embodiment 1. The difference is that the breaker hammer 54 in this embodiment is provided with a cavity 55, and a number of impact blocks 56 are placed in the cavity 55.

[0045] On a cross-section perpendicular to the axis of the hydraulic breaker 54, the outer edge of the cavity 55 is a regular polygon.

[0046] The working process and principle of this embodiment are as follows:

[0047] When the breaker 54 is not impacting the construction waste, the impact block 56 is furthest from the rotating shaft 51 and is located at one corner of the cavity 55. After the breaker 54 collides with the construction waste, the impact causes the breaker 54 and the support rod 53 to move in the opposite direction of rotation. Then the impact block 56 collides with the other corner of the cavity 55. The impact block 56 reduces the momentum of the breaker 54, allowing the support rod 53 to quickly return to a stable state, increasing the number of impacts between the impact block 56 and the construction waste, and improving the crushing efficiency of the equipment for construction waste.

[0048] Furthermore, after the impact block 56 collides with the inner wall of the cavity 55, the centrifugal force on the impact block 56 causes the breaker 54 to rotate, making the wear of the breaker 54 uniform and improving the accuracy of the rotation of the breaker 54.

[0049] Furthermore, the outer edge of cavity 55 is a square or an equilateral triangle.

[0050] Furthermore, the mass ratio of the impact block 56 to the breaker 54 inside the cavity 55 is 1.0:1.0-2.0, and both the impact block 56 and the breaker 54 are made of metal.

[0051] Example 3:

[0052] like Figure 5 As shown, this embodiment discloses a construction solid waste treatment device, whose structure is roughly the same as that of Embodiment 2. The difference is that the crushing component in 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 on the crushing component to pass through the support rod 53, thereby improving the safety of the crushing component during operation.

[0053] Example 4:

[0054] like Figure 2 , Figure 7 As shown, this embodiment discloses a construction solid waste treatment device, whose structure is roughly the same as that of Embodiment 1. The difference is that the screening component 6 in this embodiment includes a positioning rod 62, a plurality of sliding arc plates 61 are installed on the positioning rod 62, an elastic element 63 is installed between two adjacent arc plates 61, and an adjustable positioning element is installed at both ends of the positioning rod 62.

[0055] Furthermore, the elastic element 63 is an elastic rubber tube or a spring, and the positioning element is a clamp, pin, or bolt.

[0056] The working process and principle of this embodiment are as follows:

[0057] The staff adjusted the positions of the two positioning rods 62, thereby adjusting the distance between the two adjacent arc plates 61, and thus adjusting the screening size of the crushed construction solid waste.

[0058] Furthermore, the crushing component includes two breaker hammers 54, and the support rod 53 is located between the two breaker hammers 54. During the rotation of the crushing component, the two breaker hammers 54 partially overlap with one of the arc plates 61. The breaker hammers 54 strike the construction solid waste stuck between the two adjacent arc plates 61, thereby improving the screening efficiency of the screening component 6 for construction solid waste.

[0059] Example 5:

[0060] like Figure 2 , Figure 7 As shown, this embodiment discloses a construction solid waste treatment device, whose structure is roughly the same as that of Embodiment 1. The difference is that the screening component 6 in this embodiment includes a positioning rod 62, and a plurality of parallel arc-shaped plates 61 are fixed on the positioning rod 62.

[0061] The working process and principle of this embodiment are as follows:

[0062] The crushed construction waste falls through the gap between adjacent curved plates 61, thus achieving the screening of construction waste.

[0063] Example 6:

[0064] like Figure 1 , Figure 4 As shown, this embodiment discloses a construction solid waste treatment device, whose structure is roughly the same as that of Embodiment 1. The difference is that this embodiment also includes a drive frame 1, and one end of each rotating shaft 51 is rotatably connected to the drive frame 1.

[0065] The operator fixes the power output shaft of the external motor and the drive frame 1 through a coupling, and the operator drives the external motor to rotate the drive frame 1, which in turn drives the crushing component 5 to rotate. The drive frame 1 facilitates the operation of the external motor.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
