Description

Technical Field

[0001] This invention relates to the field of construction waste treatment technology, and in particular to a high-efficiency waste treatment device for construction projects. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines and devices. During the construction process, a lot of construction waste containing reinforced concrete is often generated. The construction waste left over from construction is processed by crushing and reuse to facilitate the production of aggregates of various specifications and standards during reuse.

[0003] For example, in the prior art, there is a construction waste processing device disclosed in CN118874627A. This invention crushes large bricks containing tie bars, nails, etc., into powder after they are placed in a crushing and cutting device, thus completing the processing of waste. However, this device is difficult to target the crushing of construction waste of different sizes during the crushing process, and the construction waste often contains a lot of moisture before processing, which leads to inefficient crushing and adhesion during the crushing process.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a high-efficiency construction waste treatment device. It utilizes a vibrating screen conveyor mechanism to screen and move construction waste simultaneously. During the movement of the construction waste, a fan and heating pipes are used for drying, preventing excessive internal moisture from hindering subsequent crushing. After screening, the construction waste moves into the crushing and feeding assembly, allowing for targeted crushing of construction waste of different specifications. The crushed bone meal is then fed into the assembly, thus achieving an integrated effect of screening, drying, conveying, crushing, and discharging, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency waste treatment device for construction projects, comprising a treatment box, a fixed base for fixing the treatment box, a conveyor belt rotatably connected inside the fixed base, a feed inlet on one side of the treatment box corresponding to the top of the conveyor belt, and a vibrating screen conveying mechanism installed inside the treatment box corresponding to the feed inlet, a crushing and feeding assembly installed inside the treatment box on one side of the vibrating screen conveying mechanism, several fans fixed on the top layer inside the treatment box corresponding to the position above the vibrating screen conveying mechanism, and a heating pipe fixed on the top layer inside the treatment box corresponding to the position above the fans.

[0007] Furthermore, the vibrating screen conveying mechanism includes a support frame disposed inside the processing box. A second screen plate, a first screen plate, and a support plate are sequentially fixed inside the fixed base from top to bottom. Several fixed sleeve rods are equidistantly fixed at the bottom of the support frame. A lifting rod is slidably connected inside each fixed sleeve rod. An eccentric shaft is rotatably connected to the bottom of the lifting rod, extending through and to the outside of the fixed sleeve rod. Rotary discs are fixed to both ends of the eccentric shaft. One end of each rotary disc is fixed with a rotating shaft rotatably connected inside the processing box. A first synchronous pulley is fixed to the front end of one of the rotating shafts, extending through and to the outside of the processing box. A first synchronous belt is rotatably connected between each adjacent first synchronous pulley. A first motor is fixed to the front end of one of the first synchronous belts.

[0008] Furthermore, several fixing blocks are symmetrically and equidistantly fixed at the front and rear ends of the support frame, and a groove is provided inside the processing box at the position corresponding to the spring. Two springs are symmetrically fixed inside the groove at the upper and lower ends of the fixing blocks.

[0009] Furthermore, the crushing and feeding assembly includes three crushing chambers located inside the processing box at the side positions corresponding to the vibrating screen conveying mechanism. The interiors of the three crushing chambers are rotatably connected from top to bottom to two first crushing rollers, two third crushing rollers, and two second crushing rollers, and augers are rotatably connected to the bottom layer of the interior of each crushing chamber at the positions below the first, third, and second crushing rollers.

[0010] Furthermore, gears are fitted and fixed to the outer rear end of the first, third, and second crushing rollers within the crushing chamber, and the front and rear ends of one of the first, third, and second crushing rollers extend to the outside of the processing box and are respectively fixed with a second synchronous wheel and a third synchronous wheel.

[0011] Furthermore, a second synchronous belt is rotatably connected between each adjacent second synchronous pulley, and a second motor is fixed to the front end of one of the second synchronous pulleys.

[0012] Furthermore, the front end of the auger extends through and to the outside of the processing box, and a discharge port is fixed at the front end of the processing box corresponding to the position of the auger. A fourth synchronous pulley is fixed at the rear end of the auger extending through and to the outside of the processing box. The third synchronous pulley and the fourth synchronous pulley are rotatably connected by a third synchronous belt.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. The present invention is provided with a vibrating screen conveying mechanism. The first motor, together with the first synchronous belt and the first synchronous pulley, drives the rotating shaft to rotate. The rotation of the rotating shaft, together with the rotating disk and the eccentric shaft, drives the lifting rod to rise and fall in a cycle, thereby creating a lifting effect of a certain frequency on the fixed sleeve rod. The support frame is lifted and supported by the spring to vibrate. With the vibration, the first screen plate and the second screen plate screen the construction waste according to a certain size specification, so as to facilitate subsequent crushing. At the same time, with the vibration of the support frame, the construction waste moves accordingly. With the help of the heating pipe and the fan, the damp construction waste is dried, which makes it easier to crush in the subsequent process and improves the overall crushing effect.

[0015] 2. In this invention, a crushing and feeding assembly is provided inside the processing box at the position corresponding to the side of the vibrating screen conveying mechanism. The second motor, in conjunction with the second synchronous belt and the second synchronous wheel, drives the three crushing rollers to rotate. At the same time, gears are used to drive all the crushing rollers to rotate. The three crushing rollers are suitable for three different specifications of construction waste, so as to better crush the construction waste and avoid the situation where the crushing effect of construction waste is poor due to mismatch of specifications. At the same time, when the three crushing rollers rotate, they work with the third synchronous wheel and the third synchronous belt to drive the three augers to rotate, thereby forming a feeding effect on the crushed construction waste.

[0016] In summary, the vibrating screen conveyor mechanism screens and moves construction waste simultaneously. During the movement of the construction waste, a fan and heating pipe are used to dry it, preventing excessive moisture inside the construction waste from hindering subsequent crushing. After screening, the construction waste moves into the crushing and feeding assembly, where construction waste of different specifications is crushed in a targeted manner, and the crushed bone meal is fed into the assembly. This achieves an integrated effect of screening, drying, conveying, crushing, and discharging. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: This example addresses the problem that most existing construction waste treatment devices process all types of construction waste together, making it difficult to screen different types of construction waste and hindering subsequent crushing and recycling.

[0028] like Figure 1-6As shown, a high-efficiency waste treatment device for construction projects includes a treatment box 1, a fixed base 3 for the treatment box 1, a conveyor belt 2 rotatably connected inside the fixed base 3, and a built-in power source for driving the conveyor belt 2 installed inside the fixed base 3. A feed inlet 32 ​​is provided on one side of the treatment box 1 at the top position of the conveyor belt 2, and a vibrating screen conveying mechanism 13 is installed inside the treatment box 1 at the position corresponding to the feed inlet 32. The vibrating screen conveying mechanism 13 includes a support frame 33 set inside the treatment box 1. A second screen plate 20, a first screen plate 19 and a support plate 18 are fixed inside the fixed base 3 from top to bottom. The second screen plate 20, the first screen plate 19 and the support plate 18 are all inclined at an angle to the horizontal direction. Thus, when the second screen plate 20, the first screen plate 19 and the support plate 18 vibrate, they will drive the construction waste to move. At the same time, the screen hole size inside the second screen plate 20 is larger than the screen hole size inside the first screen plate 19.

[0029] Several fixed sleeve rods 23 are fixed at equal intervals at the bottom of the support frame 33. A lifting rod 22 is slidably connected inside the fixed sleeve rod 23. The bottom of the lifting rod 22 passes through and extends to the outside of the fixed sleeve rod 23 and is rotatably connected to an eccentric shaft 24. A rotating disk 21 is fixed at both the front and rear ends of the eccentric shaft 24. A rotating disk 21 is fixed at one end of the rotating disk 21 and is rotatably connected to a rotating shaft 15 inside the processing box 1. A first synchronous pulley 6 is fixed at the front end of one of the rotating shafts 15, which passes through and extends to the outside of the processing box 1. A first synchronous belt 5 is rotatably connected between each adjacent first synchronous pulley 6. A first motor 4 is fixed at the front end of one of the first synchronous belts 5.

[0030] Several fixing blocks 16 are symmetrically and equidistantly fixed at the front and rear ends of the support frame 33. A groove 34 is provided inside the processing box 1 at the position corresponding to the spring 17. Two springs 17 are symmetrically fixed inside the groove 34 at the upper and lower ends of the fixing blocks 16. The support frame 33 is supported by the springs 17. When the support frame 33 is subjected to external force, it will vibrate to a certain extent. Several fans 12 are fixed at the position above the vibrating screen conveying mechanism 13 inside the top layer of the processing box 1. A heating pipe 11 is fixed at the position above the fans 12 inside the top layer of the processing box 1.

[0031] Construction waste is placed on the upper surface of the conveyor belt 2 and transported to the processing box 1. The construction waste falls into the vibrating screen conveyor mechanism 13. The first motor 4 is started, and the first synchronous belt 5 and the first synchronous wheel 6 drive the rotating shaft 15 to rotate. The rotation of the rotating shaft 15, together with the rotating disk 21, drives the eccentric shaft 24 to rotate. The rotation of the eccentric shaft 24 drives the lifting rod 22 to rise and fall, thereby creating a lifting effect of a certain frequency on the fixed sleeve rod 23. The fixed sleeve rod 23 is lifted by the lifting rod 22 and supported by the spring 17 to form a continuous vibrating screen effect. The construction waste is separated into certain sizes by the second screen plate 20 and the first screen plate 19 and moves continuously with the vibration. At the same time, during the movement, the heating pipe 11 and the fan 12 are started to dry the damp construction waste to avoid excessive moisture inside the construction waste.

[0032] Example 2: This example addresses the problem in existing construction waste treatment devices where, during the crushing process, different sizes of construction waste cannot be completely crushed using the same crushing roller, resulting in insufficient crushing of some waste and affecting the overall recycling process.

[0033] like Figure 7-8 As shown, the embodiment is a high-efficiency waste treatment device for construction engineering. It also has a crushing and feeding assembly 14 installed inside the treatment box 1 on one side of the vibrating screen conveying mechanism 13. The crushing and feeding assembly 14 includes three crushing chambers 35 opened inside the treatment box 1 at the position corresponding to the side of the vibrating screen conveying mechanism 13. The three crushing chambers 35 are rotatably connected from top to bottom to two first crushing rollers 25, two third crushing rollers 28 and two second crushing rollers 26. The first crushing rollers 25 are suitable for crushing large-sized construction waste, the third crushing rollers 28 are used for crushing medium-sized construction waste, and the second crushing rollers 26 are suitable for crushing small-sized construction waste. In this way, construction waste of different sizes can be crushed more thoroughly. And the bottom of the interior of the crushing chamber 35 is rotatably connected to the auger 27 at the position below the first crushing rollers 25, the third crushing rollers 28 and the second crushing rollers 26. The bottom of the interior of the crushing chamber 35 has a circular structure similar to the auger 27.

[0034] Gears 31 are fitted and fixed inside the crushing chamber 35 on the outer rear end of the first crushing roller 25, the third crushing roller 28, and the second crushing roller 26. The gears 31 drive the two first crushing rollers 25, the two third crushing rollers 28, and the two second crushing rollers 26 to rotate relative to each other, forming a crushing effect. The front and rear ends of one of the first crushing rollers 25, the third crushing roller 28, and the second crushing roller 26 are all connected to the outside of the processing box 1 and a second synchronous wheel 10 and a third synchronous wheel 29 are fixed respectively. A second synchronous belt 9 is rotatably connected between each adjacent second synchronous wheel 10. A second motor 8 is fixed to the front end of one of the second synchronous wheels 10.

[0035] The front end of the auger 27 extends through and to the outside of the processing box 1. The front end of the processing box 1 is fixed with a discharge port 7 corresponding to the position of the auger 27. The rear end of the auger 27 extends through and to the outside of the processing box 1 and is fixed with a fourth synchronous wheel 36. The third synchronous wheel 29 and the fourth synchronous wheel 36 are connected by a third synchronous belt 30.

[0036] After the screened construction waste enters the crushing chamber 35, the second motor 8 is started, and the second synchronous belt 9 and the second synchronous pulley 10 drive one of the first crushing rollers 25, the third crushing roller 28 and the second crushing roller 26 to rotate. The gear 31 drives the other first crushing roller 25, the third crushing roller 28 and the second crushing roller 26 to rotate, thereby crushing construction waste of different specifications. The crushed construction waste falls into the bottom layer of the crushing chamber 35.

[0037] While the first crushing roller 25, the third crushing roller 28 and the second crushing roller 26 rotate, they work in conjunction with the third synchronous wheel 29, the fourth synchronous wheel 36 and the third synchronous belt 30 to drive the auger 27 to rotate, thereby creating a feeding effect on the crushed construction waste, thus forming an integrated construction waste treatment operation.

[0038] The working process and principle of this invention are as follows:

[0039] Step 1: Place the construction waste on the upper surface of the conveyor belt 2 and transport it to the processing box 1. The construction waste falls into the vibrating screen conveyor mechanism 13. Start the first motor 4, which works with the first synchronous belt 5 and the first synchronous wheel 6 to drive the rotating shaft 15 to rotate. The rotation of the rotating shaft 15, together with the rotating disk 21, drives the eccentric shaft 24 to rotate. The rotation of the eccentric shaft 24 drives the lifting rod 22 to rise and fall, thereby creating a lifting effect on the fixed sleeve rod 23 at a certain frequency. The fixed sleeve rod 23 is lifted by the lifting rod 22 and supported by the spring 17 to form a continuous vibrating screen effect. The construction waste is separated into certain sizes by the second screen plate 20 and the first screen plate 19 and moves continuously with the vibration. At the same time, during the movement, the heating pipe 11 and the fan 12 are started to dry the damp construction waste to avoid excessive moisture inside the construction waste.

[0040] Step 2: After the screened construction waste enters the crushing chamber 35, the second motor 8 is started, and the second synchronous belt 9 and the second synchronous pulley 10 drive one of the first crushing rollers 25, the third crushing roller 28 and the second crushing roller 26 to rotate. The gear 31 drives the other first crushing roller 25, the third crushing roller 28 and the second crushing roller 26 to rotate, thereby crushing construction waste of different specifications. The crushed construction waste falls into the bottom layer of the crushing chamber 35.

[0041] While the first crushing roller 25, the third crushing roller 28 and the second crushing roller 26 rotate, they work in conjunction with the third synchronous wheel 29, the fourth synchronous wheel 36 and the third synchronous belt 30 to drive the auger 27 to rotate, thereby creating a feeding effect on the crushed construction waste, thus forming an integrated construction waste treatment operation.

[0042] In summary, the construction waste is transported to the processing box 1 by the conveyor belts 2, and the construction waste is screened by the vibrating screen conveyor mechanism 13 to achieve the desired size and transport effect. The construction waste is dried by the heating pipe 11 and the fan 12, which fully prepares the construction waste for subsequent crushing. Then, the crushing and feeding assembly 14 is used to crush the construction waste of different sizes accordingly to avoid poor crushing effect and facilitate subsequent recycling.

[0043] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
