Description

Technical Field

[0001] The present invention relates to the technical field of concrete post-processing, in particular to a concrete waste processing device. Background Art

[0002] During the production of tubular piles, the extrusion molding process generates a large amount of concrete waste, primarily consisting of uncured concrete residue, slurry from equipment washing, and debris from mold cleaning. This waste originates primarily from three sources: First, approximately 5%-8% of uncured concrete remains on the mold walls during the extrusion molding process; and second, the high-water content slurry mixture generated during equipment cleaning. Currently, the industry's approach to handling this waste is relatively crude, with direct landfill or open-air dumping common practices. This not only results in significant resource waste but also creates numerous environmental issues. According to statistics, every 1,000 meters of tubular piles produced generates approximately 2-3 tons of concrete waste, containing 30%-50% recycled aggregate and incompletely hydrated cement. Direct disposal results in an annual loss of over 2 million tons of construction material resources. Furthermore, the alkaline substances in this waste can alter the soil pH through leachate, while the fine particulate matter can easily form dust pollution, posing long-term risks to the surrounding ecological environment.

[0003] In view of the above-mentioned defects, the designer has actively carried out research and innovation in order to create a concrete waste treatment device to make it more valuable for industrial use. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a concrete waste treatment device.

[0005] A concrete waste processing device of the present invention includes a base fixedly installed on a foundation, a waste trough is installed on the base through a bracket, a rotatable rotating barrel is arranged in the waste trough, the outer ring of the rotating barrel is a plurality of ribs arranged at intervals, and there are gaps between the ribs. One end of the rotating barrel is a feeding part, and the bottom of the waste trough is provided with an inclined discharging part. The rotating barrel is located above the waste trough, and the discharging part classifies and discharges the mud, sand and gravel in the concrete waste.

[0006] This concrete waste processing device puts concrete waste into a rotating barrel through a feeding part. The base provides stable support, and the bracket fixes the waste trough and carries the rotating barrel. When the rotating barrel is driven to rotate, the ribs arranged at intervals on its outer ring screen the waste through the gaps. The inclined discharge part at the bottom of the waste trough guides the separated mud and gravel to different outlets according to the difference in material particle size, thereby realizing automatic classification and recycling of waste.

[0007] Furthermore, the feeding part includes a guide plate fixed to the top end of the bracket, and the lower end of the guide plate extends into the rotating barrel.

[0008] The concrete waste slides into the rotating barrel through the guide plate fixed on the top of the bracket, and the lower end of the guide plate extends into the rotating barrel to ensure the accurate introduction of the material.

[0009] Furthermore, the rotating barrel has an inwardly bent retaining ring at one end close to the guide plate, and a separating ring is provided in the middle of the rotating barrel. The spacing between the ribs on both sides of the separating ring is different, and the spacing between the ribs on the side close to the guide plate is smaller than the spacing between the ribs on the other side.

[0010] When concrete waste is introduced into the rotating barrel through the guide plate, the baffle ring prevents the material from splashing. During the rotation of the rotating barrel, the separation ring divides it into two working areas. The ribs on the side close to the guide plate have a smaller spacing to achieve fine material screening, while the ribs on the other side have a larger spacing to separate coarse materials. Finally, the materials are discharged in stages through the inclined discharge part at the bottom of the waste trough.

[0011] Furthermore, a rotating shaft is installed in the middle of the rotating barrel through a connecting rod, and both ends of the rotating shaft are fixed to the bracket through bearing seats and bearings. A driving motor is installed on one side of the bracket, and the driving motor drives the rotating shaft at one end of the rotating barrel to rotate through a pulley belt.

[0012] The driving motor drives the rotating shaft to rotate through the pulley belt, and the rotating shaft drives the rotating barrel to rotate through the connecting rod. The two ends of the rotating shaft are supported by bearing seats and bearings fixed on the bracket. During the rotation process, the rotating barrel realizes waste classification through ribs with different spacing.

[0013] Furthermore, a water pump is installed on the base, and the water pump transports the cleaning water from the water pipe to the spray pipe. There are multiple spray heads under the spray pipe, and the spray heads are evenly distributed between the separation ring and the retaining ring.

[0014] The water pump on the base transports cleaning water to the spray pipe through the water pipe. Multiple spray heads below the spray pipe are evenly distributed between the separation ring and the retaining ring to spray and clean the material in the rotating barrel. At the same time, the rotating barrel rotates driven by the drive motor, so that the material is fully separated during the cleaning process, and finally the graded discharge is completed through the inclined discharge part at the bottom of the waste trough.

[0015] Furthermore, a plurality of support rods are fixed to the top end of the bracket, and the other ends of the support rods are fixedly connected to the spray pipes.

[0016] The bracket fixes the spray pipe through the support rod, and the water pump supplies water to the spray pipe through the water pipe. The spray head cleans the material in the rotating barrel. At the same time, the driving motor drives the rotating barrel to rotate to separate the materials, and finally discharges them through the waste trough.

[0017] Furthermore, the unloading part includes an inclined plate fixedly connected to the rear plate of the waste trough, and the surface of the inclined plate is divided into a mud and sand unloading plate, a gravel unloading plate 1 and a gravel unloading plate 2 by a plurality of vertical plates. The mud and sand unloading plate is located below the rotating barrel between the dividing ring and the retaining ring, the gravel unloading plate 1 is located below the other side of the rotating barrel, and the gravel unloading plate 2 is located at the rear side of the tail end of the rotating barrel.

[0018] The inclined plate is fixed on the rear plate of the waste trough, and its surface is divided into a sediment discharge plate, a gravel discharge plate 1 and a gravel discharge plate 2, which respectively receive the fine material, coarse material and residual material discharged from different positions of the rotating barrel to achieve automatic graded unloading.

[0019] Furthermore, a vibration plate is installed on the lower side of the sediment unloading plate through a hinge, a motor mounting plate is fixed above the vertical plate of the vibration plate, a vibration motor is installed on the motor mounting plate, a pull rod is installed between the motor mounting plate and the panel of the waste trough, the end opening of the sediment unloading plate is connected to the feed port of the screw feeder, and a plurality of through slots are opened on the vibration plate, and the through slots are covered with a filter.

[0020] The vibration plate is installed on the lower side of the sediment unloading plate through a hinge. The motor mounting plate is fixed above the vertical plate of the vibration plate and the vibration motor is installed. The motor mounting plate and the waste trough panel are connected by a pull rod. The end of the sediment unloading plate is opened to connect to the feed port of the screw feeder. A through groove with a filter is provided on the surface of the vibration plate to realize material screening and transportation.

[0021] Furthermore, the pull rod is hollow, and the front end of the pull rod has a telescopic rod inserted into the pull rod, the tail end of the telescopic rod has a raised retaining ring, and a tension spring is installed between the retaining ring and the pull rod. The tail end of the telescopic rod is movably connected to the raised mounting block on the motor mounting plate through the shaft, and the rear end of the pull rod is movably connected to the raised mounting block on the waste trough panel through the shaft.

[0022] The pull rod has a hollow structure, with the front end inserted into the telescopic rod. A retaining ring is provided at the tail end of the telescopic rod and connected to the pull rod through a tension spring. The tail end of the telescopic rod is movably connected to the mounting block of the motor mounting plate through an axis, and the rear end of the pull rod is movably connected to the mounting block of the waste trough panel through an axis, thereby realizing elastic buffering and angle adjustment functions.

[0023] Furthermore, there is a water tank fixed on the base just below the vibration plate, and a partition plate is provided in the middle of the water tank to separate the water tank into a sedimentation tank and a water tank. The height of the partition plate is lower than the height of the side wall of the water tank, and the water inlet pipe of the water pump extends into the water tank.

[0024] A water tank fixed on the base is set just below the vibration plate. The water tank is divided into a sedimentation tank and a water tank by a partition plate. The height of the partition plate is lower than the side wall of the water tank to form an overflow channel. The water pump inlet pipe extends to the water tank to realize circulating water supply, forming a water supply system with sedimentation function.

[0025] By means of the above solution, the present invention has at least the following advantages: 1. Efficient graded recycling: Through the differential spacing design of the spacing ribs on the outer ring of the rotating barrel and the partitioning of the separation ring, combined with the mud and sand discharge plate, gravel discharge plate 1 and gravel discharge plate 2 at the inclined discharge part at the bottom of the waste chute, the automatic grading, screening and precise discharge of aggregates (mud, gravel) of different particle sizes in concrete waste are achieved, significantly improving the separation efficiency of recyclable aggregates.

[0026] 2. Resource recycling: During the rotary barrel screening process, the spray pipe and spray head spray and clean the material, effectively separating the aggregates attached to the cement slurry, recovering the incompletely hydrated cement and aggregates to the greatest extent, greatly reducing the waste of raw materials, and solving the problem of annual resource loss of more than 2 million tons caused by traditional landfill.

[0027] 3. Environmental pollution prevention and control: The secondary screening of the filter screen of the vibration plate and the sedimentation tank-water tank grading design realize the wastewater sedimentation purification and recycling. At the same time, the separated fine particles are collected centrally to eliminate the ecological environment risks of waste leachate changing the soil pH value and dust pollution.

[0028] 4. Structural collaborative optimization: The vibration plate adapts to the vibration load and adjusts the angle through an elastic buffer mechanism composed of a pull rod, a telescopic rod and a tension spring; the screw feeder directly connects to the screened sediment and cooperates with the circulating water supply system of the water tank to form a compact and efficient waste treatment closed loop, reducing operation and maintenance costs and improving device stability.

DETAILED DESCRIPTION

[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0034] See also Figure 1 The concrete waste enters the rotating barrel 3 through the feeding part. The base 1 provides stable support. The bracket 4 fixes the waste trough 2 and carries the rotating barrel 3. When the rotating barrel 3 is driven to rotate, the ribs arranged at intervals on its outer ring screen the waste through the gaps. The inclined discharge part at the bottom of the waste trough 2 guides the separated mud and gravel to different outlets according to the difference in material particle size. The waste is automatically graded through the gaps between the ribs of the rotating barrel 3. The inclined design of the discharge part ensures efficient separation of mud and gravel. The overall structure is compact and the processing efficiency is high, effectively solving the problem of resource waste caused by traditional waste landfill.

[0035] See also Figure 1 On the right side, the concrete waste slides into the rotating barrel 3 through the guide plate 5 fixed on the top of the bracket 4. The lower end of the guide plate 5 extends into the rotating barrel 3 to ensure accurate guidance of the material. The precise cooperation between the guide plate 5 and the rotating barrel 3 realizes the directional transportation of the waste, avoids material splashing and deviation, improves the feeding accuracy and efficiency, and simplifies the feeding structure design.

[0036] See also Figure 1 When concrete waste is introduced into the rotating barrel 3 through the guide plate 5, the baffle ring 6 prevents material from splashing. During the rotation of the rotating barrel 3, the separator ring 7 divides it into two working areas. The rib spacing on the side close to the guide plate 5 is smaller to achieve fine material screening, and the rib spacing on the other side is larger to separate coarse materials. The baffle ring 6 ensures stable feeding, and the separator ring 7 cooperates with the differentiated rib spacing to achieve simultaneous and efficient grading of coarse and fine aggregates, significantly improving the waste processing accuracy and production capacity.

[0037] See also Figure 1The driving motor 8 drives the rotating shaft 9 to rotate through the pulley belt transmission. The rotating shaft 9 runs stably on the bracket 4 through the bearing seat and bearing, and drives the rotating barrel 3 to perform screening operations through the connecting rod. The bearing seat support structure ensures the long-term and reliable rotation of the rotating shaft 9. The overall power transmission is efficient and maintenance is simple, which significantly improves the service life and operation stability of the equipment.

[0038] See also Figure 1-Figure 3 After the water pump 10 is started from the base 1, the cleaning water is transported to the spray pipe 12 through the water pipe 11, and a fan-shaped water curtain is formed through the spray heads 13 evenly distributed between the separation ring 7 and the retaining ring 6, which dynamically flushes the rotating material. After flushing, the mud and gravel can be separated.

[0039] The multiple support rods 14 on the top of the bracket 4 form a spatial truss structure, which is rigidly fixed to the bracket 4 and the spray pipe 12 through flange connections at both ends, providing support for the spray pipe 12.

[0040] See also Figure 2 and Figure 4 The inclined plate 15 is separated by vertical plates to form three functional areas: the sediment discharge plate 16, the first gravel discharge plate 17, and the second gravel discharge plate 18. These areas correspond to the discharge ports at different locations of the rotating barrel 3. When the equipment is in operation, the screened fine-grained material falls between the separation ring 7 and the retaining ring 6 onto the sediment discharge plate 16. Medium-sized aggregate enters the first gravel discharge plate 17 from the side of the rotating barrel, and large-sized aggregate is guided from the rear end to the second gravel discharge plate 18. This structural design achieves precise material diversion through physical partitioning. The different inclination angles of each discharge plate ensure smooth discharge. The entire system is rigidly connected to the rear plate of the waste chute 2 to ensure operational stability.

[0041] See also Figure 4 The sediment mixture slides from the sediment discharge plate 16 to the vibration plate 19 connected by a hinge below. The vibration motor 21 drives the vibration plate 19 to generate high-frequency vibration through the motor mounting plate 20. The pull rod 22 maintains the stability of the system. During the vibration process, fine particles are screened for the second time through the through groove covered with the filter screen. The purified material finally enters the screw feeder 23 through the end opening to complete the transportation. The hinge installation method of the vibration plate 19 is convenient for maintenance and inspection. The seamless connection between vibration screening and spiral conveying ensures the continuity of processing. The multi-layer filter screen design improves the separation efficiency of fine particles. The overall structure achieves dynamic balance through the pull rod 22, which effectively reduces the equipment operation noise and wear.

[0042] When the vibration motor 21 is running, the vibration generated is transmitted to the telescopic rod 24 through the motor mounting plate 20. The telescopic rod 24 slides axially in the inner cavity of the pull rod 22. The retaining ring at its tail end and the tension spring 25 between the pull rod 22 form an elastic buffer. The two ends are connected through a movable shaft and are flexibly linked with the motor mounting plate 20 and the waste trough 2 panel respectively. The socket structure of the hollow pull rod 22 and the telescopic rod 24 realizes three-dimensional shock absorption, and the elastic deformation of the tension spring 25 effectively absorbs vibration impact.

[0043] The sewage generated during the screening process of the vibrating plate 19 falls directly into the water tank 26 fixed on the base 1 below. The water tank is divided into a sedimentation tank 27 and a water tank 28 by a partition plate 29. Since the height of the partition plate 29 is lower than the side wall of the water tank, the clean water after sedimentation can overflow into the water tank 28. The water pump 10 pumps water from the water tank 28 through the water inlet pipe to realize the recycling of water resources.

[0044] The working principle of the present invention is as follows: When the concrete waste processing device is working, the collected waste is circulated from the right guide plate 5 and input into the rotating barrel 3. The rotating barrel 3 starts to rotate under the drive motor 8. At the same time, the water pump 10 transports the water in the water tank 28 to the spray pipe 12, and the water is evenly sprayed on the right side of the rotating barrel 3 by the spray head 13. After the rotation and flushing, the mud and gravel particles are separated. At the same time, the small particles of gravel fall from the small gap between the ribs on the right side of the rotating barrel 3 and are discharged along the mud and sand discharge plate 16. The silt and small-particle gravel slide down to the vibrating plate 19, and after being vibrated at the vibrating plate 19, they slowly slide down to the feed port of the screw feeder 23, and the silt and small-particle gravel are transported to the rear-end aggregate. At the same time, the water in the silt slurry drips from the filter screen at the groove of the vibrating plate 19 into the sedimentation tank 27. The water at this time is relatively turbid and contains a certain amount of silt. After sedimentation, the precipitated water overflows from the partition plate 29 into the water tank 28, which is convenient for the water pump 10 to take, thereby realizing water circulation.

[0045] The stones of middle size slowly move to the left side of the rotating barrel 3 and fall onto the stone unloading plate 17 on the left side of the rotating barrel 3. The stones of middle size are discharged through the stone unloading plate 17 for collection.

[0046] The larger stones cannot be sieved on the left side of the rotating barrel 3 and are finally discharged from the tail end of the rotating barrel 3 and slide onto the stone discharge plate 2 18 , through which the larger stones are discharged and collected.

[0047] After a certain period of use, the mud material in the sedimentation box 27 becomes more and more, and it is necessary to stop the machine and perform manual cleaning.

[0048] The water tank 28 can be connected to a water source through a water inlet pipe. The water source is tap water, which is used to supplement the consumed water.
