Description

Technical Field

[0001] This utility model relates to the field of construction waste crushing technology, specifically to a crushing device for energy-saving and environmentally friendly construction. Background Technology

[0002] Building energy conservation refers to minimizing energy consumption during the production of building materials, construction of buildings and structures, and their use, while meeting the same needs or achieving the same purpose. Construction often generates large amounts of waste or building debris, necessitating the use of shredders to crush these materials. A search revealed existing technology (Publication No.: CN202122177697.8) for a building energy-saving and environmentally friendly shredding device. The document describes that "this building energy-saving and environmentally friendly shredding device, equipped with an inlet pipe, an outlet pipe, and an atomizing nozzle, allows the user to utilize the flange..." The plate serves as a connector, allowing the water inlet pipe and corresponding dust suppressant pump to be installed into the equipment, facilitating the introduction of the dust suppressant. On the other hand, the water inlet pipe allows the dust suppressant to be added into the interior of the guide plate. The guide plate is then uniformly welded with an outlet pipe at the end near the bottom of the crushing chamber's feed inlet, and an atomizing nozzle is threadedly connected to the end of the outlet pipe. This allows the dust suppressant to be sprayed evenly near the feed inlet, improving the dust suppression effect and achieving environmental benefits. Furthermore, the threaded installation structure facilitates the disassembly and maintenance of the atomizing nozzle. However, in existing technologies, the nozzle needs to continuously spray water to suppress dust during continuous crushing, leading to excessive water consumption in the crushing device and easy clogging of the nozzle. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a pulverizing device for building energy conservation and environmental protection is provided to solve the problem that in existing technologies, the nozzle needs to continuously spray water to suppress dust during continuous pulverization, resulting in excessive water consumption and easy clogging of the nozzle.

[0004] To achieve the above objectives, a pulverizing device for building energy conservation and environmental protection is provided, comprising: a waste pulverizer body, a feed bin fixed to the upper end face of the waste pulverizer body, and a bin cover hinged to the upper surface of the feed bin. The inner wall of the waste crusher is equipped with a primary crushing roller mechanism and a secondary crushing roller mechanism. A dust conveyor is embedded and fixed in the right side wall of the waste crusher. A motor is fixed on the right end face of the dust conveyor. A drive shaft is connected to the left side of the motor. An impeller and a spiral blade are installed on the shaft surface of the drive shaft. The lower end of the dust conveyor is connected to a dust suppression water tank through a water immersion pipe. The upper end face of the dust suppression water tank is connected to the groove on the surface of the bin cover through a vent pipe.

[0005] Furthermore, a conveyor belt is installed inside the waste crusher, with a two-stage crushing roller mechanism distributed at the upper left end of the conveyor belt and a dust conveyor distributed at the upper right end.

[0006] Furthermore, a secondary crushing roller mechanism is provided at the lower end of the primary crushing roller mechanism, and a discharge port is opened on the lower end face of the waste crusher body; and the discharge port is located at the lower right end of the conveyor belt.

[0007] Furthermore, a brush roller is installed at the upper left end of the discharge port, and a discharge cover plate is connected to the lower end of the discharge port through a discharge hose. A material blocking plate is inserted into the inner side of the discharge cover plate.

[0008] Furthermore, a dust suppression water tank is supported on the right side of the waste crusher body, and a dust outlet pipe is connected to the lower end of the dust suppression water tank. A valve is installed on the surface of the dust outlet pipe.

[0009] Furthermore, the dust suppression water tank has a water inlet on its upper surface; and the surface of the water inlet is sealed with a rubber plug, and an immersion pipe is inserted into the inside of the dust suppression water tank.

[0010] Furthermore, the left side of the drive shaft is connected to the inner wall of the waste crusher via a sealed bearing, and the impeller and spiral blades are located at the left port and inner wall of the dust conveyor, respectively.

[0011] The beneficial effects of this utility model are as follows: The energy-saving and environmentally friendly pulverizing device for buildings utilizes an impeller and spiral blades installed on the inner shaft surface of a dust conveyor. The rotating impeller and spiral blades transport the dust gas generated during pulverization into the water in the dust suppression tank, allowing the high-speed flowing dust gas to fully settle into the water. The cleaned gas flows back into the pulverizer body, achieving a pulverizing device with anti-clogging dust suppression function. This effectively reduces the water consumption during the pulverizing and dust suppression process, thus saving water and protecting the environment. It also helps prevent dust gas from clogging pipes or nozzles, reducing malfunctions caused by blockages, ensuring stable operation of the pulverizing device for dust suppression, and improving the overall operating efficiency of the pulverizing device.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a pulverizing device for building energy conservation and environmental protection, including: a waste pulverizer body 1, a feed bin 2 fixed to the upper end face of the waste pulverizer body 1, and a bin cover 21 hinged to the upper surface of the feed bin 2. The inner wall of the waste crusher body 1 is equipped with a primary crushing roller mechanism 6 and a secondary crushing roller mechanism 61. A dust conveyor 3 is embedded and fixed in the right wall of the waste crusher body 1. A motor 31 is fixed on the right end face of the dust conveyor 3. A drive shaft 32 is connected to the left side of the motor 31. An impeller 33 and a spiral blade 34 are installed on the shaft surface of the drive shaft 32. The lower end of the dust conveyor 3 is connected to a dust suppression water tank 4 through a water immersion pipe 42. The upper end face of the dust suppression water tank 4 is connected to the groove on the surface of the bin cover 21 through a vent pipe 22.

[0018] First, construction waste is poured into the waste crusher body 1 through the feed hopper 2. After being crushed by the primary crushing roller mechanism 6 and the secondary crushing roller mechanism 61, the waste falls onto the conveyor belt 11 and is then conveyed to the right by the conveyor belt 11 and discharged into the collection frame through the discharge cover plate 5. During the crushing process, the motor 31 drives the impeller 33 and the spiral blades 34 on the transmission shaft 32 to rotate. The rotating impeller 33 transports the dust generated in the waste crusher body 1 to the dust conveyor 3. The spiral blades 34 then immerse the dust entering the dust conveyor 3 into the dust suppression water tank 4 through the immersion pipe 42, causing the dust to settle at the bottom of the water. The gas flows back into the waste crusher body 1 through the vent pipe 22, effectively reducing the water consumption during the crushing and dust suppression process. This has the functions of saving water and protecting the environment, and helps prevent dust and gas from clogging pipes or nozzles and other devices, reducing the failure of devices caused by blockage, and ensuring the stable operation of the dust suppression treatment of the crushing device.

[0019] In this embodiment, a conveyor belt 11 is installed inside the waste crusher body 1. A secondary crushing roller mechanism 61 is distributed at the upper left end of the conveyor belt 11, and a dust conveyor 3 is distributed at the upper right end. The secondary crushing roller mechanism 61 is provided at the lower end of the primary crushing roller mechanism 6, and a discharge port 13 is opened on the lower end face of the waste crusher body 1; and the discharge port 13 is located at the lower right end of the conveyor belt 11.

[0020] As a preferred embodiment, the secondary crushing roller mechanism 61 is an existing crushing mechanism, mainly composed of a pair of crushing rollers, a rotating shaft, a belt, a drive wheel, and a motor, which crushes the waste material entering between the rollers. The conveyor belt 11 facilitates the transport of the crushed waste material to the right, reducing the flow of dust and gas to the discharge port 13.

[0021] In this embodiment, a brush roller 12 is installed at the upper left end of the discharge port 13, and a discharge cover plate 5 is connected to the lower end of the discharge port 13 through a discharge hose 51. A material blocking plate 52 is inserted into the inner side of the discharge cover plate 5.

[0022] In a preferred embodiment, the brush roller 12 cleans the waste material remaining on the conveyor belt 11. The discharge cover plate 5 is pressed down and adheres to the surface of the collection frame to prevent dust raised during the feeding process from flowing to the outside. The baffle plate 52 controls the falling of waste material in the discharge hose 51.

[0023] In this embodiment, a dust suppression water tank 4 is supported on the right side of the waste crusher body 1. A dust outlet pipe 41 is connected to the lower end of the dust suppression water tank 4, and a valve is installed on the surface of the dust outlet pipe 41. A water inlet 43 is provided on the upper surface of the dust suppression water tank 4; and a rubber plug is used to seal the surface of the water inlet 43. An immersion pipe 42 is inserted into the inside of the dust suppression water tank 4.

[0024] As a preferred embodiment, the dust outlet pipe 41 at the lower end of the dust suppression water tank 4 facilitates the discharge of dust particles that have settled to the bottom of the water. The water inlet 43 facilitates the replenishment of water into the dust suppression water tank 4. The immersion pipe 42 facilitates the immersion of high-speed rotating dust gas into the water, allowing the dust gas to fully contact the water and settle.

[0025] In this embodiment, the left side of the drive shaft 32 is connected to the inner wall of the waste crusher body 1 through a sealed bearing, and the impeller 33 and the spiral blade 34 are located at the left port and the inner wall of the dust conveyor 3, respectively.

[0026] In a preferred embodiment, the drive shaft 32 drives the impeller 33 and the spiral blades 34 to rotate. The impeller 33 first transports the dust gas generated in the waste crusher body 1 to the dust conveyor 3, and then moves to the right through the spiral blades 34 and enters the immersion pipe 42. In this process, the spiral blades 34 can also transport the dust particles accumulated in the dust conveyor 3 to the immersion pipe 42, thereby achieving the effect of preventing blockage. This helps to reduce the failure of the device caused by blockage, ensures the stable operation of the dust suppression treatment of the crushing device, and improves the overall operating efficiency of the crushing device.

[0027] This utility model of a pulverizing device for building energy conservation and environmental protection effectively solves the problem in existing technologies where continuous water spraying during pulverization leads to excessive water consumption and easy clogging of the nozzles. It achieves a pulverizing device with anti-clogging dust suppression function, effectively reducing water consumption during the pulverization and dust suppression process. This results in water conservation and environmental protection, preventing dust and gas from clogging pipes or nozzles, reducing malfunctions caused by blockages, ensuring stable operation of the dust suppression process, and improving the overall operating efficiency of the pulverizing device. It is suitable for pulverizing devices used in building energy conservation and environmental protection.
