Description

Technical Field

[0001] This invention relates to the field of waste soil treatment technology, and more specifically, to a device for treating construction waste soil. Background Technology

[0002] During civil construction, most of the construction waste soil is usually transported to waste disposal sites for storage or landfilled in the open sea. This not only incurs high disposal costs, but also has a serious impact on soil quality, air quality, and water quality due to long-term stockpiling, and poses safety hazards. It has always been a rather thorny problem.

[0003] Preliminary testing and evaluation of construction waste materials in the laboratory is beneficial for understanding their composition and for the scientific and rational allocation and reuse of these materials. Because construction waste materials vary in size, laboratory testing requires pulverizing the materials and then sieving them multiple times to obtain powder that meets experimental requirements. Currently, there is no integrated processing equipment for construction waste materials on the market. Pulverizing requires a pulverizer, and sieving requires different precision sieving equipment, making the experimental operation complex, requiring a large amount of equipment, and necessitating multiple material transfers. This process is prone to sample contamination, which can affect the performance evaluation of construction waste materials and compromise the accuracy of the experiments. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a construction waste soil treatment device. This device has a series of functions such as crushing, coarse screening, fine screening, and drying. Construction waste soil materials can meet the experimental preparation requirements in one go. This device can greatly reduce the difficulty of experimental operation and effectively reduce the occurrence of sample contamination. Through this device, dry experimental material powder that meets the fineness requirements can be obtained efficiently, which is conducive to improving the accuracy of detection experiments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction waste treatment device includes a main body and an electric heating drying chamber. The main body is provided with a feed inlet. From top to bottom, a crushing roller assembly, a coarse screening mechanism, a fine screening mechanism, and an output mechanism are installed inside the main body. Two electric heating drying chambers are respectively installed on both sides of the main body. Two fine powder discharge ports are opened on the bottom side wall of the main body. The two fine powder discharge ports are respectively set to correspond to the two electric heating drying chambers. The fine powder discharge ports connect the main body and the electric heating drying chambers. The output mechanism extends into the electric heating drying chamber through the fine powder discharge ports.

[0007] Furthermore, the coarse screening mechanism includes a screen cylinder, a support frame, and a screen cylinder motor. The screen cylinder is rotatably mounted on two supports, which are fixedly connected to the inner wall of the main housing. A transmission gear is fixedly connected to one end of the screen cylinder, and a drive gear is connected to the output end of the screen cylinder motor. The drive gear meshes with the transmission gear. A collection hopper is installed between the crushing roller assembly and the coarse screening mechanism. The collection hopper is vertically connected, and the outer wall of the screen cylinder covers and closes the lower opening of the collection hopper. The outer wall of the screen cylinder maintains dynamic contact with the lower opening of the collection hopper, and several screening holes are opened on the outer wall of the screen cylinder.

[0008] Furthermore, the fine screening mechanism includes a screen plate and a vibrator. A guide seat is installed between the fine screening mechanism and the coarse screening mechanism. The guide seat has a discharge port. The screen plate is installed in the discharge port. The screen plate is connected to the vibrator. A spring and a telescopic rod are connected and installed below the screen plate. The spring and the telescopic rod are installed vertically.

[0009] Furthermore, the output mechanism includes a discharge plate, two discharge plates are arranged symmetrically, the discharge plates are installed at an angle, the high point of the discharge plate extends to the position directly below the sieve plate, and the low point of the discharge plate extends into the electric heating drying oven after passing through the fine powder discharge port. A discharge conveyor belt is installed on the discharge plate.

[0010] Furthermore, a comber is installed between the feed inlet and the crushing roller assembly. The comber includes a horizontal shaft and combing plates. The horizontal shaft is fixedly connected to the main housing. Two combing plates are symmetrically connected to the horizontal shaft, forming a V-shaped structure. The opening of the V-shaped structure is located directly below the feed inlet, and the tip of the V-shaped structure faces the centerline of the crushing roller assembly. Each combing plate has several material passage holes.

[0011] Furthermore, the comb plate is flipped and connected to the horizontal shaft. The comber also includes two opening and closing drive components, which are respectively set to correspond to the two comb plates. The opening and closing drive components include a push cylinder frame and an opening and closing push cylinder. The push cylinder frame is fixedly installed in the main housing. The tail end of the opening and closing push cylinder is hinged to the push cylinder frame. The piston rod end of the opening and closing push cylinder is connected to the comb plate.

[0012] Furthermore, two side baffles are connected between the two comb plates, and a storage space is formed by the two comb plates and the two side baffles surrounding each other. The two opening and closing push cylinders extend and retract synchronously, which can drive the two comb plates to rotate synchronously, so that the size of the storage space can change. Several comb needles are fixedly connected to the side of the comb plate facing the storage space.

[0013] Furthermore, the main housing includes a crushing and processing housing, a coarse screening and processing housing, a fine screening and processing housing, and connecting bolts. The crushing and processing housing, the coarse screening and processing housing, and the fine screening and processing housing are assembled sequentially from top to bottom and connected by connecting bolts. The crushing roller assembly is installed inside the crushing and processing housing. The coarse screening mechanism is installed on the top of the coarse screening and processing housing. The fine screening mechanism and the output mechanism are installed inside the fine screening and processing housing. Two symmetrically arranged dust removal devices are connected and installed on the side wall of the crushing and processing housing.

[0014] Furthermore, several shock-absorbing pads are installed at the bottom of the fine screening processing box.

[0015] The beneficial effects of this invention are:

[0016] 1. This invention uses a pulverizing roller assembly to achieve the pulverizing effect of construction waste soil, and employs a coarse sieve and a fine sieve mechanism to perform two-stage screening of the pulverized material to obtain sample material that meets the fineness requirements. The sample material is then dried using an electric heating drying oven. This invention has a series of functions including pulverizing, coarse sieve, fine sieve, and drying, and can prepare construction waste soil powder in one step. The application of this invention can greatly reduce the difficulty of experimental operation, effectively reduce the occurrence of sample contamination, and help improve the accuracy of detection experiments.

[0017] 2. The present invention is designed with a comber, which has an opening and closing function and can form a compression pretreatment effect on the incoming construction waste soil material, so that the particle diameter of the construction waste soil material falling from the comber is significantly reduced. The comber can effectively reduce the working pressure of the crushing roller group and improve the crushing efficiency and crushing quality of the crushing roller group.

[0018] 3. The main body of the present invention adopts a three-layer split structure design, and the disassembly of each functional box is convenient, which is conducive to the cleaning and maintenance of the internal mechanism. Attached Figure Description

Detailed Implementation

[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] like Figures 1-6The illustrated construction waste treatment device includes a main housing 1 and an electric heating drying chamber 6. The main housing 1 has a feed inlet 11 for feeding construction waste material samples. Inside the main housing 1, from top to bottom, are a crushing roller assembly 2, a coarse screening mechanism 3, a fine screening mechanism 4, and an output mechanism 5. The crushing roller assembly 2 includes two symmetrically arranged crushing rollers with crushing teeth to crush hard materials. The crushing roller assembly 2 is driven by a motor. The crushing roller assembly 2 is existing technology and will not be described in detail here. In this invention, the crushing roller assembly 2 functions to crush construction waste. The purpose of the soil sample is to address the issue that, even after pulverizing, the construction waste soil sample still contains particles of varying sizes. Directly using this sample for testing could affect the accuracy of the results. Therefore, this invention also includes a coarse sieve mechanism 3 and a fine sieve mechanism 4 to screen the pulverized sample. These two mechanisms provide two screening processes, ensuring that the final powder of the construction waste soil sample meets the experimental requirements in terms of particle size. The construction waste soil sample powder is output through an output mechanism 5, and two electrically heated drying ovens 6 are installed in the main chamber. On both sides of the main body 1, two fine powder outlets 12 are opened on the bottom side wall. The two fine powder outlets 12 are respectively set to correspond to two electric heating drying ovens 6. The fine powder outlets 12 connect the main body 1 and the electric heating drying ovens 6. The output mechanism 5 extends into the electric heating drying oven 6 through the fine powder outlets 12. During the experiment, the construction waste soil material sample input cannot be completely dry. Therefore, the sample powder obtained also contains a certain amount of moisture. The output mechanism 5 can input the finally obtained sample powder into the electric heating drying oven 6 for drying to finally obtain dry sample powder. This facilitates subsequent testing operations. The electric drying oven 6 is a conventional drying device on the market, and its structure will not be described in detail here. The final dried powder is taken out from the electric drying oven 6. The present invention has a reasonable structural layout and has a series of functions such as crushing, coarse sieving, fine sieving, and drying. Construction waste soil material powder can be prepared in one go. The application of the present invention can greatly reduce the difficulty of experimental operation. Since the construction waste soil material does not need to be transferred back and forth between multiple devices, it can effectively reduce the occurrence of sample contamination and help improve the accuracy of testing experiments.

[0028] like Figure 2 and Figure 5As shown, the coarse screening mechanism 3 includes a screen cylinder 31, a support 32, and a screen cylinder motor 34. The screen cylinder 31 is rotatably mounted on two supports 32, which are fixedly connected to the inner wall of the main housing 1. A transmission gear 33 is fixedly connected to one end of the screen cylinder 31. The screen cylinder motor 34 is fixedly installed inside the main housing 1, and a drive gear 35 is connected to the output end of the screen cylinder motor 34. The drive gear 35 meshes with the transmission gear 33. After the screen cylinder motor 34 starts, it drives the screen cylinder 31 to rotate through the meshing relationship between the drive gear 35 and the transmission gear 33. A collection hopper 21 is installed between the crushing roller group 2 and the coarse screening mechanism 3. The collection hopper 21 is vertically connected and has the function of collecting and outputting the crushed material. The collection hopper 21 has a large upper opening and a small lower opening. The material crushed by the crushing roller group 2 falls down the wall of the collection hopper 21. The outer wall of the screen cylinder 31 covers and closes the lower opening of the collection hopper 21, so that the crushed material can continue to fall. The material must pass through the screen cylinder 31, which achieves a screening effect. Since the screen cylinder 31 rotates, its outer wall and the lower opening of the collecting hopper 21 maintain dynamic contact. This seals the lower opening of the collecting hopper 21 without affecting its free rotation. All crushed materials must pass through the screen cylinder 31. Several screening holes 311 are provided on the outer wall of the screen cylinder 31. These holes screen the material, allowing only particles that meet the size requirements of the screening holes 311 to pass through and continue falling. Because the screening holes 311 have relatively large diameters, they provide a coarse screening effect. Designing the screen cylinder 31 to rotate helps prevent clogging. Since the screen cylinder 31 rotates, all screening holes 311 on the cylinder wall can be fully utilized. Furthermore, during the rotation of the screen cylinder 31, the collecting hopper 21 can scrape away blockages on the cylinder wall, keeping the screening holes 311 unobstructed.

[0029] like Figure 2 As shown, the fine screening mechanism 4 includes a screen plate 41 and a vibrator 42. A guide seat 45 is installed between the fine screening mechanism 4 and the coarse screening mechanism 3. The guide seat 45 is used to collect the powder after coarse screening. The guide seat 45 has a discharge port 451. The powder after coarse screening falls down the wall of the guide seat 45 and is output from the discharge port 451. The screen plate 41 is installed in the discharge port 451. The screen plate 41 is movably installed and is connected to the vibrator 42. The vibrator 42 drives the screen plate 41 to vibrate up and down in the discharge port 451. Using common equipment available on the market, this is existing technology and will not be described in detail here. The size of the screen plate 41 matches the material discharge port 451. The mesh size of the holes on the screen plate 41 is smaller than the screening holes 311 on the screen cylinder 31. All the coarse powder output from the material discharge port 451 passes through the fine screening process of the screen plate 41. A spring 43 and a telescopic rod 44 are connected and installed below the screen plate 41. The spring 43 and the telescopic rod 44 are installed vertically. The spring 43 can improve the vibration elasticity of the screen plate 41, and the telescopic rod 44 plays the role of guiding the movement of the screen plate 41, so that the screen plate 41 can achieve vertical lifting and vibration.

[0030] like Figure 2 and Figure 6 As shown, the output mechanism 5 includes two discharge plates 51 arranged symmetrically. The discharge plates 51 are installed at an angle, with the high point of the discharge plate 51 extending directly below the sieve plate 41. The fine powder sieved from the sieve plate 41 falls precisely at the high point of the discharge plate 51 and then falls naturally down the discharge plate 51. The low point of the discharge plate 51 extends into the electric drying oven 6 after passing through the fine powder discharge port 12. To improve the smoothness of powder discharge, a discharge conveyor belt 52 is installed on the discharge plate 51. The fine powder sieved from the sieve plate 41 falls precisely on the discharge conveyor belt 52 and is then carried by the discharge conveyor belt 52 into the electric drying oven 6. The electric drying oven 6 can dry the powder. The final experimental powder is taken out from the electric drying oven 6. The powder has undergone two screenings, and the fineness of the powder meets the experimental requirements. After being dried in the electric drying oven 6, the powder is in a dry powder state and can be directly used in the testing experiment.

[0031] Because construction waste materials have complex compositions and varying particle sizes, directly pouring them into the crushing roller assembly 2 for crushing will not yield ideal results, and the amount of fine powder meeting experimental requirements will be relatively small. Therefore, if... Figure 2 As shown, a comber 7 is installed between the feed inlet 11 and the crushing roller assembly 2. The comber 7 can pre-comb the construction waste material poured into the equipment to improve the crushing effect of the crushing roller assembly 2. The comber 7 includes a horizontal shaft 71 and combing plates 72. The horizontal shaft 71 is fixedly connected inside the main housing 1. The two combing plates 72 are symmetrically connected to the horizontal shaft 71, forming a V-shaped structure. The opening of the V-shaped structure is located directly below the feed inlet 11, which is exactly where the construction waste poured into the equipment from the feed inlet 11 is received. The waste soil material has a V-shaped structure with its tip aligned with the centerline of the crushing roller assembly 2 (i.e., the central area of ​​the crushing roller assembly 2). Each comb plate 72 has several material passage holes 721. The poured-in construction waste soil material is stored within the V-shaped structure formed by the comb plate 72. Slag particles smaller than the diameter of the material passage holes 721 can pass directly through the material passage holes 721 and fall down. The falling position is located in the central area of ​​the crushing roller assembly 2 (i.e., the meshing position of the two crushing rollers), achieving rapid and thorough crushing. Figure 2 As shown, in this invention, the comb plate 72 and the horizontal shaft 71 are connected by a flip connection. The comber 7 also includes two opening and closing drive assemblies 75, which are respectively set to correspond to the two comb plates 72. The opening and closing drive assembly 75 includes a push cylinder frame 751 and an opening and closing push cylinder 752. The push cylinder frame 751 is fixedly installed in the main housing 1. The tail end of the opening and closing push cylinder 752 is hinged to the push cylinder frame 751. The piston rod end of the opening and closing push cylinder 752 is connected to the comb plate 72. The opening and closing push cylinder 752 can drive the corresponding comb plate 72 to flip through the extension and retraction of the piston rod. Figure 3As shown, two side baffles 73 are connected between the two comb plates 72. A storage space 74 is formed by the two comb plates 72 and the two side baffles 73 surrounding each other. The storage space 74 can hold the poured construction waste material. The side baffles 73 act as lateral barriers, preventing the waste from overflowing from the sides when the comb plates 72 move. Simultaneously, the side baffles 73 are expandable and do not affect the flipping movement of the comb plates 72. The piston rods of the two opening and closing push cylinders 752 extend and retract synchronously, causing the two comb plates 72 to flip synchronously, thus creating changes in the size of the storage space 74 (e.g., ...). Figure 4 As shown, the construction waste material in the storage space 74 can be shaken, causing waste particles smaller than the diameter of the through hole 721 to be quickly screened off. The change in the size of the storage space 74 can also compress large pieces of construction waste material, breaking them into smaller particles that fall. However, this effect is not very obvious. Therefore, in this invention, the comb plate 72 is designed with several comb needles 722 fixedly connected to the side of the plate facing the storage space 74. Utilizing the flipping motion of the comb plate 72 and the changing effect of the storage space 74, the comb needles 722 can continuously insert or withdraw from the waste particles, effectively breaking large pieces of waste particles into smaller pieces that fall. The design of the comber 7 can play a preliminary treatment role for the poured material. Since the waste particles input from the comber 7 are significantly smaller, the workload of the subsequent crushing roller group 2 is significantly reduced, which can improve the crushing quality of the crushing roller group 2, making the crushed waste finer and producing more fine powder that meets the experimental requirements.

[0032] like Figure 2 As shown, the main housing 1 includes a crushing and processing housing 15, a coarse screening and processing housing 16, a fine screening and processing housing 17, and connecting bolts 18. The crushing and processing housing 15, coarse screening and processing housing 16, and fine screening and processing housing 17 are assembled sequentially from top to bottom and connected by connecting bolts 18. The crushing roller assembly 2 is installed inside the crushing and processing housing 15. The coarse screening mechanism 3 is installed on the top of the coarse screening and processing housing 16. The fine screening mechanism 4 and the output mechanism 5 are installed inside the fine screening and processing housing 17. This invention divides the main housing 1 into three parts: the crushing and processing housing 15, the coarse screening and processing housing 16, and the fine screening and processing housing 17. Each of the three processing housings has a movable door, allowing for... The three processing chambers can be easily disassembled and combined. They are also designed to facilitate cleaning and maintenance of the components inside the main chamber 1 after the experiment. Two symmetrically arranged dust removal devices 13 are connected and installed on the side wall of the crushing and processing chamber 15. During the crushing operation, dust will fly around. If it is not removed, the dust will fill the crushing and processing chamber 15. There is a risk of overflow when the movable door of the crushing and processing chamber 15 is opened. Therefore, the dust removal device 13 is designed to remove dust in real time. The dust removal device 13 can be a commonly used negative pressure dust removal device on the market. This is existing technology, and its structure and principle will not be described in detail here.

[0033] like Figure 1 and Figure 2 As shown, several shock-absorbing pads 14 are installed at the bottom of the fine screening processing box 17. During the operation of this invention, there will be vibration. The shock-absorbing pads 14 can reduce the vibration of the equipment. The shock-absorbing pads 14 are purchased from existing products on the market. The shock-absorbing pads 14 have shock absorption and height adjustment functions.

[0034] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
