DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Reference Manual Attached Figure 1 and Figure 2 As shown, a recycling device for building decoration waste includes: Box body 1, the bottom end of box body 1 is installed on the bottom plate through a column; The vibration screening mechanism 2 includes a first filter plate 3 movably connected to the inner wall of the box body 1, and both ends of the outer wall of the first filter plate 3 are installed with side plates 5 fixed on the vibration motor 4. The bottom of the first filter plate 3 is installed on the bottom plate through an elastic airbag 6, and one end of the first filter plate 3 is in contact with the inner wall of the box body 1, and the other end is movably connected to the sealing plate 7; The working principle of the vibration motor 4 is based on the adjustable eccentric blocks installed at both ends of the rotor shaft. When the vibration motor 4 rotates, the centrifugal force generated by these eccentric blocks forms an exciting force, thereby causing the vibration motor 4 to vibrate. This vibration can make the motor move up and down to achieve material screening, and cooperate with the tilt setting of the first filter plate 3 to achieve the conveying of construction waste.

[0023] The bottom of the vibration screening mechanism 2 is supported and connected to the second spring 41, and is movably connected to the inner wall of the box body 1. A gap is formed between the upper side plate 5 of the vibration motor 4 and the side wall of the box body 1. In this way, the vibration screening mechanism 2 can avoid interference between structural parts when it is moving, thereby ensuring the stability of the mechanism's operation. In addition, the sealing plate 7 at one end of the side plate 5 can not only protect against construction waste, but also provide a movable space for the up and down movement of the side plate 5, thereby preventing the side plate 5 from deviating from its position during movement.

[0024] A vibration screening mechanism 2 is provided, and construction waste enters the first filter plate 3 of the box body 1 through the conical material guide port 42. At this time, the vibration motor 4 is started, and cooperates with the second spring 41 to drive the first filter plate 3 and the side plate 5 to vibrate up and down, so that the debris in the metal parts can be discharged through the filter holes. In this way, the metal parts and the debris can be initially vibrated and separated by the action of vibration screening, thereby improving the separation effect, thereby improving the recycling quality of decorative waste, ensuring that resources can be effectively recycled, and being beneficial to environmental protection.

[0025] refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 , lifting and screening mechanism 8, the lifting and screening mechanism 8 includes an air inlet pipe 9 and an air outlet pipe 10 placed at both ends of the elastic airbag 6, a one-way valve 11 adapted thereto is installed on the air inlet pipe 9, one end of the air outlet pipe 10 extends to a three-way pipe 12, and both ends of the air outlets on the three-way pipe 12 are connected to the lifting assembly 13; Among them, the lifting assembly 13 includes a pushing block 14 placed on the inner wall of the slide groove, the top of the pushing block 14 is connected to the second filter plate 16 through a fixing rod 15, and the pushing block 14 and the bottom end of the inner wall of the box body 1 are connected through a first spring 17, and the second filter plate 16 is in contact with and fits with a third filter plate 18 fixed on the inner wall of the box body 1 along the garbage transmission direction, and one end of the second filter plate 16 fits with the opening on the sealing plate 7.

[0026] Specifically, the first filter plate 3 , the second filter plate 16 and the third filter plate 18 are all arranged to be tilted downward in the same direction. The second filter plate 16 is connected to an inclined groove 19 along the height direction of the third filter plate 18 . The inclined groove 19 is provided with a limiting portion 20 that is in contact with the second filter plate 18 .

[0027] The specific working principle of the lifting and screening mechanism 8 is as follows: During the downward movement of the elastic airbag 6 under the force, the gas in the elastic airbag 6 is pushed to the three-way pipe 12 through the outlet pipe 10, and then the gas is transported to the push block 14 through the gas ports at both ends of the three-way pipe 12. Since there is a sealed cavity between the push block 14 and the inner wall of the box body 1, when it is affected by external gas, the pressure increases, and the push block 14 moves the second filter plate 16 upward through the fixing rod 15. The second filter plates 16 are arranged at intervals, and a third filter plate 18 is arranged between the two. With the help of the air collection of the elastic airbag 6 and The elastic restoring force of the first spring 17 can move the second filter plate 16 in the opposite direction, so that the second filter plate 16 can move up and down. During the movement, the metal parts in the construction waste can be lifted and screened. At the same time, when the second filter plate 16 moves, one end moves along the inclined groove 19, and the other end extends along the inner wall slide groove of the box body 1 to move, which can effectively play a role in guiding the activity. Moreover, the limiting part 20 on the inclined groove 19 can also play a corresponding resistance and support role, giving the second filter plate 16 corresponding support force when it moves.

[0028] A lifting and screening mechanism 8 is provided. When the vibrating screening mechanism 2 moves up and down, it can drive the elastic airbag 6 to extend and retract. A one-way valve 11 is provided on the air inlet pipe 9 to prevent gas leakage. In this way, under the flow of gas, the second filter plate 16 connected to the push block 14 can move up and down, and cooperate with the third filter plate 18 fixedly provided on the inner wall of the box body 1 to further lift and screen the slag on the metal parts. In addition, the vibration source of the vibration motor 4 is used to realize the up and down movement, and there is no need to set up an additional power source, which saves resources and improves the stability of the device.

[0029] In addition, the one-way valve 11 arranged on the air inlet pipe 9 can prevent the gas from being discharged from the air inlet pipe 9 during the downward pressure of the elastic airbag 6, thereby causing only part of the gas to flow into the sealed cavity formed by the push block 14, resulting in a situation where the pressure is too low and the push block 14 cannot be driven to move normally.

[0030] refer to Figure 3 , Figure 4 , Figure 8 and Fig. 9 A recycling device for building decoration waste also includes a spreading and cleaning mechanism 21, which includes a driving motor 22 placed on the box body 1. The output shaft of the driving motor 22 passes through the box body 1 and extends to the first transmission wheel 23 and the screw shaft 24 in sequence. The screw shaft 24 is spirally driven with a first screw nut fixed on the cross beam 25. The extension sections on both sides of the bottom end of the cross beam 25 are connected to the sealing plate 7 by plugging. As the driving motor 22 is started, the first screw nut drives the sealing plate 7 to open or close at the opening.

[0031] The first transmission wheel 23 and the second transmission wheel 26 on the inner wall of the box body 1 are connected through a conveyor belt 27. The outer wall of the first bevel gear 28 on the second transmission wheel 26 is meshed with a second bevel gear 30 fixed on the reciprocating screw 29. The reciprocating screw 29 is spirally driven with a second screw nut installed on a slider 31. Both ends of the slider 31 are connected to the spread plate 32 through bending rods. The spread plate 32 and the third filter plate 16 are connected through a partition 33 fixed on the side wall of the box body 1.

[0032] After the drive motor 22 is started, it can not only control the up and down movement of the movable sealing plate 7, but also drive the work of the spreading cleaning mechanism 21. During the movement of the sealing plate 7, the opening can be opened, so that the construction waste after vibration screening can enter the lifting and screening mechanism 8 for secondary screening. Moreover, after the drive motor 22 is started, it can drive the rotation of the first transmission wheel 23. Through the transmission connection setting of the conveyor belt 27, the first bevel gear 28 on the second transmission wheel 26 can be driven to rotate. With the help of the meshing transmission between the gears, the reversing adjustment can be realized and the reciprocating screw 29 on the second bevel gear 30 can be driven to rotate. In this way, under the action of the spiral transmission, the slider 31 can move back and forth in the horizontal direction.

[0033] The partition plate 33 between the spreading plate 32 and the third filter plate 18 is provided to serve as a transition guide, and the partition plate 33 itself is also inclined, so that the metal parts after vibration screening can slide smoothly onto the dewatering plate 39. At the same time, a certain height difference is formed between the spreading plate 32 and the dewatering plate 39, which can facilitate the spreading of the screened metal parts and prevent the accumulation of construction waste at a certain location, which is not conducive to effective cleaning.

[0034] When the slider 31 drives the fan-shaped nozzle 36 on the movable plate 34 to move back and forth, in order to ensure the normal movement of the fan-shaped nozzle 36, a corrugated hose 35 is provided. Due to the elastic expansion and contraction function of the corrugated hose 35 itself, the normal spraying and cleaning of the fan-shaped nozzle 36 can be prevented from being affected when the movable plate 34 moves, and one end of the corrugated hose 35 can be connected to the fan-shaped nozzle 36 by a threaded connection, which can facilitate the rapid installation of the structural parts and facilitate the operation of personnel. As for other bolt connections and positioning pin locking and fixing methods, the present invention does not describe them in detail, which are conventional technical means for those skilled in the art.

[0035] Specifically, a movable plate 34 is connected to the bottom of the slider 31, and a fan-shaped nozzle 36 connected to the corrugated hose 35 is installed on the movable plate 34. One end of the corrugated hose 35 is connected to a water tank 38 placed on the box body 1 through a pump body 37. A dehydration plate 39 placed on the inner wall of the box body 1 is provided below the fan-shaped nozzle 36. The dehydration plate 39 is provided with equidistantly distributed dehydration grooves 40, and the dehydration plate 39 is a movable pull-out design. A strip groove connected to the dehydration plate 39 is provided in the length direction of the inner wall of the box body 1. The filter hole on the first filter plate 3 has a diameter of 1-3 cm, and a limiting groove connected to the side plate 5 is provided in the height direction of the inner wall of the box body 1. The limiting groove on the inner wall of the box body 1 also provides a movable space for the movement of the side plate 5, and can prevent it from leaving the moving track. At the same time, the filter hole on the first filter plate 3 can effectively guide the debris into the collection box.

[0036] A spreading and cleaning mechanism 21 is provided. After the driving motor 22 is started, it can drive the rotation of the screw shaft 24 and, through the action of the spiral transmission, enable the closing plate 7 to move up and down, so that the opening on the closing plate 7 can be opened or closed, and then the construction waste after vibration screening can be introduced into the lifting and screening mechanism 8. At the same time, when the closing plate 7 moves up and down, the second transmission wheel 26 on the conveyor belt 27 is rotated by means of the mechanical rotation, and then the vertical rotation force is converted into horizontal rotation force through the meshing transmission between the gears and drives the rotation of the reciprocating screw 29. Under the action of the spiral transmission, the spreading plate 32 moves back and forth, and the construction waste on the dewatering plate 39 can be spread out, and the spraying mechanism can perform back and forth water spraying work, so that the metal parts can be cleaned, so as to facilitate direct recycling in the subsequent sequence, and the pull-out movable design of the dewatering plate 39 can effectively facilitate personnel operation and improve work efficiency.

[0037] refer to Figure 3 and Figure 5 The bottom end of the first filter plate 3 is connected to a bracket placed on the bottom plate through a second spring 41, and a conical material guide port 42 placed on the outer wall of the box body 1 is provided above the first filter plate 3. The vibration motor 4 is symmetrically arranged relative to the center of the first filter plate 3. A gap is provided between the side plate 5 and the side wall of the box body 1, and a vibration cavity is formed between the side plate 5, the sealing plate 7, the first filter plate 3 and the inner wall of the box body 1. A collection box placed on the inner wall of the box body 1 is detachably installed directly below the first filter plate 3.

[0038] The collection box on the inner wall of the box body 1 can be used to collect the debris after vibration screening in the construction waste, so as to facilitate its centralized processing in the subsequent sequence. Moreover, the structural parts on the vibration screening mechanism 2 can be fixedly connected by splicing installation. On the one hand, it is convenient for installation and disassembly. On the other hand, the product can be quickly repaired and replaced in case of damage, and the operation is simple.

[0039] The dewatering groove 40 on the dewatering plate 39 can help to drain the cleaned water, thereby helping to drain the metal parts. By extension, a fan assembly can be adaptively added to the slider 31, so that when the slider 31 moves, the fan assembly can perform uniform air-drying operations, which is beneficial to the air-drying of the metal parts and can quickly help the water evaporate. At the same time, the conveyor belt 27 arranged between the first transmission wheel 23 and the second transmission wheel 26 can play a role in power transmission, supplement the adjustment of the transmission distance, and effectively transmit the power to the second transmission wheel 26.
