Description

Technical Field

[0001] This application relates to the field of furniture manufacturing, and in particular to an environmentally friendly furniture waste screening device. Background Technology

[0002] In furniture production, a lot of wood is used. Some of this wood is for single use. Workers usually pile up some waste wood in a corner of the factory for later centralized processing. In some small factories, piling up a large amount of waste wood not only takes up space, but also the fine wood chips have a high recycling value. If they are piled up together and left unattended, it will result in a waste of resources. Furthermore, dry wood chips piled together are flammable and can easily cause a fire if exposed to an open flame, posing a safety hazard. Utility Model Content

[0003] To address the issues that piling up large amounts of waste wood not only occupies space, but also that fine wood chips have high recycling value and would lead to resource waste if left unattended, and that dry wood chips piled together are flammable and could easily cause a fire if exposed to an open flame, posing a safety hazard, this application provides an environmentally friendly waste screening device for furniture.

[0004] The environmentally friendly furniture waste screening device provided in this application adopts the following technical solution:

[0005] An environmentally friendly furniture waste screening device includes a rectangular frame, with a hopper embedded inside the rectangular frame. The hopper contains an inclined secondary screen. Springs are located at the four corners of the bottom surface of the secondary screen. A rectangular plate is located on the bottom surface of each spring. A base frame is located on the bottom surface of the rectangular frame. Two connecting plates are located on the side wall of the rectangular frame opposite to the base frame. A water pipe passes between the two connecting plates. A branch pipe is located on the outer wall of the water pipe, and a spray head is located at the free end of the branch pipe.

[0006] Preferably, one end of each of the two water pipes passes through a connecting plate and extends outward to connect to an inlet pipe. The branch pipes are provided in multiples and are distributed horizontally at equal intervals.

[0007] Preferably, the top surface of the rectangular frame is provided with two upright plates at both ends, and the height of the two upright plates on the left is higher than the height of the two upright plates on the right.

[0008] Preferably, support rods are provided on the opposite side walls of the four upright plates, and a vibrating screen is provided between the four support rods. The output end of the vibrating screen is connected to a primary discharge trough.

[0009] Preferably, a discharge port is provided through one side of the outer wall of the hopper, the discharge port is connected to a secondary discharge trough, the secondary discharge trough corresponds to the inclined lower end of the secondary screen, and a box is provided below the hopper.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. The vibrating screen performs primary screening of wood chips. Wood chips larger than the mesh size of the primary screen are discharged from the primary discharge chute through the output end of the vibrating screen for centralized processing. Wood chips smaller than the mesh size of the primary screen fall onto the secondary screen in the hopper for further screening. Due to the elasticity of the four springs, the secondary screen vibrates up and down in the hopper as the wood chips fall onto it. After primary screening, wood chips larger than the mesh size of the secondary screen are discharged from the secondary discharge chute through the discharge port for centralized processing. Wood chips smaller than the mesh size of the secondary screen fall into the box through the output end of the hopper for centralized processing. The primary and secondary screens separate wood chips of different sizes for separate collection and processing, facilitating secondary processing by subsequent workers and reducing resource waste.

[0012] 2. Water from the outside can be delivered into the water pipe through the inlet pipe, and then the water in the water pipe is delivered into each branch pipe. Finally, the water is sprayed out through the spray head. The water sprayed out by the spray head can wet the dust generated during the operation of the device, effectively preventing the dust from being stirred up, making it highly practical.

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses an environmentally friendly furniture waste screening device, referring to... Figure 1 and Figure 3The system includes a rectangular frame 3, with a hopper 1 fixedly embedded inside. A secondary screen 2, inclined in shape, is movably mounted inside the hopper 1. Springs 13 are fixedly mounted at the four corners of the bottom surface of the secondary screen 2. A rectangular plate 14 is fixedly mounted on the bottom surface of each spring 13, and the rectangular plate 14 is fixedly connected to the inner wall of the hopper 1. A discharge port is provided through one side of the outer wall of the hopper 1, and a secondary discharge trough 11 is fixedly connected to the discharge port. The secondary discharge trough 11 corresponds to the inclined lower end of the secondary screen 2. A box 12 is movably mounted below the hopper 1. Two upright plates 8 are fixedly mounted at both ends of the top surface of the rectangular frame 3, with the height of the two upright plates 8 on the left being higher than the height of the two upright plates 8 on the right. Support rods 7 are fixedly mounted on the opposite side walls of the four upright plates 8. A vibrating screen 6 is fixedly mounted between the four support rods 7. A primary discharge trough 5 is fixedly connected to the output end of the vibrating screen 6. The mesh diameter of the primary screen on the vibrating screen 6 is larger than that of the secondary screen. The wood chips are initially screened by the vibration of the primary screen 6 through the mesh diameter of the vibrating screen 6. Wood chips larger than the mesh size of the primary screen are discharged from the primary discharge chute 5 through the output end of the vibrating screen 6 for centralized processing. Wood chips smaller than the mesh size of the primary screen fall onto the secondary screen 2 in the hopper 1 for further screening. Due to the elasticity of the four springs 13, the wood chips falling onto the secondary screen 2 cause the secondary screen 2 to vibrate up and down in the hopper 1. After primary screening, wood chips larger than the mesh size of the secondary screen 2 are discharged from the discharge port through the secondary discharge chute 11 for centralized processing. Wood chips smaller than the mesh size of the secondary screen 2 fall into the box 12 through the output end of the hopper 1 for centralized processing. The wood chips of different sizes are screened by the primary screen and the secondary screen 2 and then collected and processed separately, which facilitates the secondary processing of the wood chips by the subsequent staff and reduces the waste of resources.

[0019] Reference Figures 1-2 A base frame 4 is fixedly installed on the bottom surface of the rectangular frame 3. Two connecting plates are fixedly installed on the side wall opposite to the base frame 4 of the rectangular frame 3. A water pipe 10 is fixedly inserted between the two connecting plates. A branch pipe is fixedly installed on the outer wall of the water pipe 10. A spray head 9 is fixedly installed at the free end of the branch pipe. One end of each of the two water pipes 10 passes through the connecting plate and extends outward and is fixedly connected to the water inlet pipe. There are multiple branch pipes, which are horizontally and equidistantly distributed. The water source outside can be transported into the water pipe 10 through the water inlet pipe. Then the water source in the water pipe 10 is transported into each branch pipe and finally sprayed out through the spray head 9. The water sprayed by the spray head 9 can wet the dust generated during the operation of the device, effectively preventing the dust from being stirred up, which is highly practical.

[0020] The implementation principle of the environmentally friendly furniture waste screening device in this application embodiment is as follows: During use, the wood chips are initially screened by the vibration of the primary screen 6. Wood chips with a volume larger than the mesh size of the primary screen are discharged from the primary discharge chute 5 through the output end of the vibrating screen 6 for centralized processing. Wood chips with a volume smaller than the mesh size of the primary screen fall onto the secondary screen 2 in the hopper 1 for further screening. Due to the elasticity of the four springs 13, the wood chips falling onto the secondary screen 2 cause the secondary screen 2 to vibrate up and down within the hopper 1. After primary screening, wood chips with a volume larger than the mesh size of the secondary screen 2 are discharged through the discharge port into the secondary discharge trough 11 for centralized processing. Wood chips with a volume smaller than the mesh size of the secondary screen 2 fall into the box 12 through the output end of the hopper 1 for centralized processing. At the same time, external water can be transported into the water pipe 10 through the water inlet pipe. Then, the water in the water pipe 10 is transported into each branch pipe and finally sprayed out through the spray head 9. The water sprayed through the spray head 9 can wet the dust generated during the operation of the device, effectively preventing the dust from being stirred up.
