Description

Technical Field

[0001] The invention relates to the technical field of construction waste treatment, and in particular to a device for classifying and treating construction waste materials. Background Art

[0002] Construction waste, also known as building garbage, is solid waste generated during the construction, maintenance and demolition of buildings. It mainly includes waste concrete blocks, waste bricks and tiles, waste wood, waste metals, waste plastics and other components. The waste concrete blocks and waste bricks and tiles in the construction waste can be crushed to obtain recycled aggregates, but these recycled aggregates often contain impurities such as soil and dust. They need to be cleaned by processing equipment to remove impurities in the recycled aggregates, improve their cleanliness and quality, so that they can be better used in the production of recycled concrete, recycled bricks and other building materials, and reduce pollution to the environment.

[0003] At present, in the treatment of construction waste materials, impeller sand washing machines are usually used for classification and treatment. The impeller sand washing machine drives the water flow through the rotation of the impeller to stir and wash the construction waste in the hopper, thereby removing the soil, impurities, etc. in the waste. In addition, during the rotation of the impeller, the vibration motor installed on the outer shell of the sand washing machine can further improve the treatment efficiency and quality of the waste materials. However, since the sand and gravel have a certain surface roughness, there are many tiny pores and pits on its surface. When the sand and gravel come into contact with water, due to the surface tension of water, water molecules will form a thin water film in these tiny pores and pits, so that a certain amount of water is adsorbed on the surface of the sand and gravel. Simple vibration cannot effectively eliminate the moisture contained in the construction waste in the hopper. This moisture will increase the mud content of the sand and gravel, thereby affecting the particle grading and fineness modulus of the sand and gravel. At the same time, in order to ensure the cleaning effect, more water is needed, which will lead to a waste of water resources.

[0004] Therefore, it is necessary to provide a device for classifying and processing construction waste materials to solve the above problems. Summary of the invention

[0007] As a further improvement of the above scheme, the reset mechanism includes a fixed plate uniformly fixedly connected to the water washing wheel, a plurality of the fixed plates are fixedly connected to a limiting rod each other, the outer sides of the limiting rods are slidably connected to a movable plate, the movable plate is fixedly connected to the connecting plate, a spring is fixedly connected between the movable plate and the fixed plate, and the spring is sleeved on the outer side of the limiting rod.

[0008] As a further improvement of the above solution, the pushing mechanism includes a driving shaft rotatably connected to the top of the sand washing tank through a clamp, the outer side of the driving shaft is symmetrically fixedly connected with a mounting sleeve, and the outer side of the mounting sleeve is evenly fixedly connected with an actuating plate.

[0009] As a further improvement of the above scheme, the support assembly also includes a fixing rod rotatably connected to the inside of support sleeve 1 and support sleeve 2, and one end of the fixing rod close to support sleeve 1 is fixedly connected to a fixing block, and the fixing block is fixedly connected to the support seat.

[0010] As a further improvement of the above scheme, the drainage component includes a sealing sleeve symmetrically fixedly connected to the sand washing tank, the interiors of the two sealing sleeves are rotatably connected to the same fixed shaft, and the outer side of the fixed shaft is evenly fixedly connected to the drainage plate.

[0011] As a further improvement of the above scheme, the anti-blocking component includes a mounting plate symmetrically fixedly connected to the bottom of the fixing rod, the bottom of the mounting plate is fixedly connected to a sealing plate, the interiors of the two sealing plates are rotatably connected to the same mounting shaft, and a telescopic mechanism is arranged on the outer side of the mounting shaft.

[0012] As a further improvement of the above scheme, the telescopic mechanism includes a fixed sleeve evenly fixedly connected to the outside of the mounting shaft, a telescopic plate is slidably connected inside the fixed sleeve, and a second spring is symmetrically fixedly connected between the telescopic plate and the inner wall of the fixed sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The washing wheel, the sand-scooping inclined plate and the cylindrical screen plate work together to form a hopper structure. During operation, the rotating hopper structure can drive the water flow to fully stir and wash the construction waste inside the hopper structure, and remove the soil and impurities in the waste. At the same time, the pushing mechanism at the bottom of the sand-scooping inclined plate can push the corresponding sand-scooping inclined plate to squeeze the construction waste in the hopper structure, so as to further remove the moisture between the construction waste in the hopper and improve the cleanliness and dryness of the waste. After the squeezing operation is completed, the sand-scooping inclined plate will automatically return to its original position. At this time, under the action of the existing vibration motor, the construction waste can be dispersed, which can not only ensure that the moisture in the construction waste is removed to the greatest extent, but also enable the construction waste to be stably discharged after rotating to the appropriate position, avoiding blockage problems, thereby improving the efficiency and reliability of the entire processing process. In addition, through the operation of squeezing and screening water, the demand for water resources in the subsequent processing process can be reduced, and the waste of water resources can be reduced; 2. During the rotation of the cylindrical screen plate, it can not only drive the construction waste to screen the moisture, but also rely on the friction between it and the telescopic mechanism to cause the telescopic mechanism to rotate around the installation axis as the central axis. During the rotation, as the space formed by the telescopic mechanism through the sealing plate and the cylindrical screen plate gradually decreases, it will compress the internal water flow, causing the water to flow out of the sieve holes of the cylindrical screen plate, thereby cleaning the sieve holes of the cylindrical screen plate, effectively avoiding the situation where the waste blocks the sieve holes, thereby ensuring that the subsequent treatment of the moisture in the waste can be carried out smoothly; 3. The toothed disc drives the fixed shaft to rotate by meshing with gear 2. The rotating fixed shaft drives the guide plate to push the waste material entering the sand washing tank toward the bottom of the sand washing component, thereby avoiding the accumulation of materials at the feed end of the sand washing tank and improving the uniformity of the distribution of materials at the bottom of the sand washing component. At the same time, it can also prevent the hopper structure in the sand washing component from being loaded with too little waste material when rotating. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figures 1 to 6 As shown, the present invention provides an embodiment: A device for classifying and processing construction waste materials comprises a sand washing tank 1, and further comprises: The support assembly 2 includes a support seat 21 symmetrically fixedly connected to the top of the sand washing tank 1, and the two support seats 21 are rotatably connected to the inside of the support sleeve 1 221 and the support sleeve 2 222; The sand washing assembly 3 is rotatably mounted between the two support seats 21. The sand washing assembly 3 includes symmetrically arranged water washing wheels 31. The two water washing wheels 31 are respectively fixedly connected to the outer side walls of the support sleeve 1 221 and the support sleeve 2 222. A sand-scooping inclined plate 32 is evenly slidably connected between the two water washing wheels 31. A connecting plate 34 is fixedly connected to the outer side wall of the sand-scooping inclined plate 32. A sand retaining plate 33 is fixedly connected to the outer side wall of the connecting plate 34. A reset mechanism 35 is symmetrically arranged on the side away from the two water washing wheels 31. A toothed disc 36 is fixedly connected to the end of the support sleeve 222 away from the water washing wheel 31. A pushing mechanism 37 is arranged on the top of the sand washing tank 1. A cylindrical screen plate 38 is fixedly connected between the two water washing wheels 31. A scraper bar 39 is fixedly connected to the end of the sand-scooping inclined plate 32 close to the cylindrical screen plate 38; The drainage component 4 is rotatably installed inside the sand washing tank 1 to push the sand and gravel to prevent the sand and gravel from piling up; The anti-clogging component 5 is arranged inside the cylindrical sieve plate tube 38 and is used to clean the sand and gravel in the sieve holes on the cylindrical sieve plate tube 38.

[0021] When the embodiment of the present invention is actually applied, the conveying equipment puts the construction waste materials into the sand washing pool 1. First, the support seat 21 of the support assembly 2 and the support sleeve 1 221 and the support sleeve 2 222 provide a stable support and rotation base for the sand washing assembly 3. The water washing wheel 31 in the sand washing assembly 3 rotates to drive the sand-sweeping inclined plate 32 to move. The sand retaining plate 33 on the sand-sweeping inclined plate 32 prevents sand and gravel from splashing. At the same time, the connecting plate 34 ensures the connection stability between the sand-sweeping inclined plate 32 and the sand retaining plate 33. When it is necessary to squeeze and dehydrate the construction waste, the pushing mechanism 37 pushes the sand-sweeping inclined plate 32 to squeeze the construction waste in the hopper, remove the moisture between the waste, and improve the cleanliness and dryness of the waste. After the extrusion is completed, the sand-sweeping inclined plate 32 is reset under the action of the reset mechanism 35. At this time, the cylindrical screen plate barrel 38 rotates driven by the water washing wheel 31 to screen the moisture of the construction waste, and the scraper bar 39 prevents the sand and gravel from adhering to the cylindrical screen plate barrel 38; The drainage component 4 rotates inside the sand washing tank 1, pushing the waste material entering the sand washing tank 1 to move toward the bottom of the sand washing component 3, avoiding the accumulation of materials at the feeding end of the sand washing tank 1, improving the uniformity of the distribution of materials at the bottom of the sand washing component 3, and preventing the situation where too little waste material is loaded when the hopper structure in the sand washing component 3 rotates; The anti-clogging component 5 cooperates with the anti-clogging component 5 to clean the sand and gravel in the sieve holes of the cylindrical sieve plate tube 38 to prevent the waste from clogging the sieve holes and affecting the subsequent treatment of moisture in the waste.

[0022] like Figure 3 and Figure 5 As shown, the reset mechanism 35 includes a fixed plate 352 uniformly fixedly connected to the washing wheel 31, a plurality of fixed plates 352 are fixedly connected to a limiting rod 353, the outer side of the limiting rod 353 is slidably connected with a movable plate 351, the movable plate 351 is fixedly connected to the connecting plate 34, a spring 354 is fixedly connected between the movable plate 351 and the fixed plate 352, and the spring 354 is sleeved on the outer side of the limiting rod 353.

[0023] In actual application of the embodiment of the present invention, when the pushing mechanism 37 pushes the sand-scooping inclined plate 32 to extrude the construction waste, the movable plate 351 slides along the limiting rod 353 and compresses the spring 1 354. When the force of the pushing mechanism 37 disappears, the spring 1 354 releases the elastic potential energy and pushes the movable plate 351 to slide in the opposite direction along the limiting rod 353, thereby driving the connecting plate 34 and the sand-scooping inclined plate 32 to reset. The limiting rod 353 ensures that the movement direction of the movable plate 351 is stable to prevent deviation, thereby ensuring that the sand-scooping inclined plate 32 accurately returns to the initial position after completing the extrusion operation, preparing for the next extrusion and screening operation, and ensuring the continuity and stability of the entire processing process.

[0024] like Figure 7 , Figure 8 and Fig. 9As shown, the pushing mechanism 37 includes a driving shaft 372 rotatably connected to the top of the sand washing tank 1 through a clamp 375, a mounting sleeve 373 is symmetrically fixedly connected to the outer side of the driving shaft 372, an actuating plate 374 is evenly fixedly connected to the outer side of the mounting sleeve 373, and a gear 1 371 is fixedly connected to the outer side of the driving shaft 372, and the gear 1 371 and the toothed disc 36 are meshed with each other.

[0025] In actual application of the embodiment of the present invention, the gear 1 371 and the toothed disc 36 are meshed with each other. When the sand washing assembly 3 is running, the rotation of the toothed disc 36 drives the gear 1 371 to rotate, thereby rotating the driving shaft 372. As the driving shaft 372 rotates, the cam mounting sleeve 373 fixed on the outside thereof rotates synchronously. The actuating plates 374 evenly distributed on the outside of the cam mounting sleeve 373 periodically contact the sand-scooping inclined plate 32 during the rotation process. When the actuating plates 374 contact the sand-scooping inclined plate 32, a pushing effect is generated on the sand-scooping inclined plate 32, prompting the sand-scooping inclined plate 32 to accelerate the rotation along the rotation direction of the water washing wheel 31, thereby squeezing the construction waste in the hopper. The drive shaft 372 is rotatably connected to the top of the sand washing tank 1 through the clamp 375, which ensures the stability and reliability of the drive shaft 372 during operation and prevents the drive shaft 372 from shaking or deflecting during rotation.

[0026] like Figure 3 , Figure 4 , Figure 6 and Fig.11 As shown, the support assembly 2 also includes a fixing rod 23 rotatably connected to the inside of the support sleeve 1 221 and the support sleeve 2 222 , and one end of the fixing rod 23 close to the support sleeve 1 221 is fixedly connected to a fixing block 24 , and the fixing block 24 is fixedly connected to the support seat 21 .

[0027] In actual application of the embodiment of the present invention, the fixing rod 23 is fixedly mounted on the support seat 21 through the fixing block 24, and is rotatably connected to the support sleeve 1 221 and the support sleeve 2 222, so that the anti-clogging component 5 can be supported and installed in the sand washing component 3 without affecting the rotation of the sand washing component 3.

[0028] like Figure 8 and Fig. 9 As shown, the drainage component 4 includes a sealing sleeve 44 symmetrically fixedly connected to the sand washing tank 1, the interiors of the two sealing sleeves 44 are rotatably connected to the same fixed shaft 42, the outer side of the fixed shaft 42 is evenly fixedly connected to a drainage plate 43, the outer side of the fixed shaft 42 is fixedly connected to a gear 2 41, and the gear 2 41 and the toothed disc 36 are meshed with each other.

[0029] In actual application, when the toothed disc 36 in the sand washing assembly 3 rotates, the gear 2 41 meshes with the toothed disc 36, thereby driving the fixed shaft 42 to rotate in the sealing sleeve 44, and the guide plate 43 evenly fixed on the outside of the fixed shaft 42 rotates synchronously. After the construction waste materials enter the sand washing tank 1, the rotating guide plate 43 can effectively push the sand and gravel and other materials to move toward the bottom of the sand washing assembly 3, avoiding the accumulation of materials at the feeding end of the sand washing tank 1, ensuring that the materials are more evenly distributed at the bottom of the sand washing assembly 3, and also preventing the hopper structure in the sand washing assembly 3 from being loaded with too little waste when rotating, thereby improving the efficiency and stability of the entire processing process; Among them, the setting of the sealing sleeve 44 ensures that the rotation of the fixed shaft 42 is carried out in a relatively sealed environment, reducing the impact of external impurities on the rotating mechanism, and also preventing water and fine sand from entering the rotating part during the sand washing process, reducing the wear and failure risk of the equipment.

[0030] like Figure 4 , Figure 8 , Fig.10 and Fig.11 As shown, the anti-blocking component 5 includes a mounting plate 53 symmetrically fixedly connected to the bottom of the fixing rod 23, and a sealing plate 52 is fixedly connected to the bottom of the mounting plate 53. The insides of the two sealing plates 52 are rotatably connected to the same mounting shaft 51, and a telescopic mechanism 54 is arranged on the outside of the mounting shaft 51.

[0031] When the embodiment of the present invention is actually applied, the mounting plate 53 is firmly fixed at the bottom of the fixing rod 23, providing a stable support for the sealing plate 52. The sealing plate 52 can effectively prevent water and fine sand from entering the rotating part of the mounting shaft 51 during the sand washing process, thereby ensuring the normal operation of the mounting shaft 51. When the cylindrical screen plate barrel 38 rotates, the telescopic mechanism 54 arranged on the outside of the mounting shaft 51 can drive the telescopic mechanism 54 to rotate with the mounting shaft 51 as the central axis through the friction between the telescopic mechanism 54 and the cylindrical screen plate barrel 38. During the rotation process, as the space formed between the telescopic mechanism 54 and the cylindrical screen plate barrel 38 is reduced, the internal water flow will be compressed to flow out from the sieve holes of the cylindrical screen plate barrel 38, thereby realizing the cleaning of the sieve holes of the cylindrical screen plate barrel 38, avoiding the sieve holes from being blocked by waste materials, ensuring the normal performance of the screening function of the cylindrical screen plate barrel 38, and improving the treatment efficiency of the water in the waste materials. At the same time, the anti-clogging component 5 works in coordination with the sand washing component 3, the supporting component 2 and the dredging component 4 to jointly constitute an efficient and stable system for sorting and processing construction waste materials.

[0032] like Fig.12 As shown, the telescopic mechanism 54 includes a fixed sleeve 541 evenly fixedly connected to the outside of the installation shaft 51, a telescopic plate 542 is slidably connected inside the fixed sleeve 541, and a spring 543 is symmetrically fixedly connected between the telescopic plate 542 and the inner wall of the fixed sleeve 541.

[0033] When the embodiment of the present invention is actually applied, the fixed sleeve 541 evenly fixed on the outside of the installation shaft 51 provides an installation basis for the telescopic plate 542. When the cylindrical sieve plate barrel 38 rotates and generates friction with the telescopic mechanism 54, the telescopic plate 542 will slide inside the fixed sleeve 541 under the action of friction. At this time, when the telescopic plate 542 is squeezed by the cylindrical sieve plate barrel 38, the spring 2 543 is compressed to store elastic potential energy. When the squeezing force disappears, the spring 2 543 releases the elastic potential energy to push the telescopic plate 542 to reset, so that the telescopic mechanism 54 can flexibly adapt to the rotation state and pressure changes of the cylindrical sieve plate barrel 38, and effectively realize the cleaning of the sieve holes of the cylindrical sieve plate barrel 38. In addition, during the cleaning process, the sliding of the telescopic plate 542 and the elastic action of the spring 2 543 can ensure that the cleaning force is moderate, which will not cause damage to the cylindrical sieve plate barrel 38 and can effectively remove the waste material blocking the sieve holes.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
