Description

Technical Field

[0001] This utility model relates to the field of recycled aggregate processing technology in construction, and more specifically, to a recycled aggregate processing equipment for concrete preparation. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials (such as cement), aggregates (sand, stone, etc.), water, and admixtures in a certain proportion, followed by stirring, molding, and curing. It is widely used in construction, bridges, roads, and other engineering fields. When preparing concrete, it is essential to ensure a reasonable aggregate ratio and low impurity content to guarantee the concrete's strength, durability, and other properties. Traditional aggregates rely on natural sand and gravel, which faces problems such as resource shortages and ecological damage. Therefore, the application of recycled aggregates has become an important trend.

[0003] Recycled aggregates are aggregates produced from waste concrete, construction waste, and other raw materials through processes such as crushing, screening, and washing. They can replace some natural aggregates in concrete preparation. The use of recycled aggregates can effectively reduce construction waste landfill and conserve natural resources.

[0004] In existing recycled aggregate processing technologies, crushed stone aggregates are typically pre-screened using magnetic separators to adsorb and separate metallic materials, such as reinforcing bars, nails, and screws. However, in practice, some metallic materials remain attached to or contained within concrete fragments after crushing, such as concrete fragments containing a small piece of binding wire. Existing magnetic separators lack the attraction to overcome the gravity of these fragments, preventing their adsorption and screening. Directly using concrete fragments containing metallic materials as recycled aggregate poses a significant safety hazard to buildings. Utility Model Content

[0005] The present invention provides a recycled aggregate processing equipment for concrete preparation. The problem to be solved is that existing magnetic separators have difficulty separating concrete fragments containing metal materials when screening recycled aggregates. As a result, recycled aggregates mixed with such concrete fragments will pose a great safety hazard to buildings in actual use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a recycled aggregate processing equipment for concrete preparation, comprising: a cleaning mechanism, the cleaning mechanism including a vibrating trough, a vibrating motor being provided on the vibrating trough for driving the vibrating trough to generate vibration, and the output end of the vibrating trough being inclined downward.

[0007] A screening mechanism is provided on the vibrating trough. The screening mechanism includes a screening trough, which is movably installed inside the vibrating trough. The output end of the screening trough is inclined downward. Several cleaning pipes are provided on the vibrating trough along the length of the screening trough. The cleaning pipes are located above the screening trough. A magnetic suction plate is provided on one side of the vibrating trough. An inclined plate and a horizontal plate are provided at the bottom of the screening trough. The inclined plate is located on the side closer to the magnetic suction plate.

[0008] In a preferred embodiment, a sorting mechanism is provided at the output end of the screening tank. The sorting mechanism includes a vortex sorting cylinder fixedly installed at the bottom of the screening tank. A drive assembly is provided on one side of the screening tank, and the output end of the drive assembly is fixedly connected to the vortex sorting cylinder.

[0009] In a preferred embodiment, a baffle is provided at the bottom of the screening tank, and the baffle is located on the opposite side of the output end of the vibrating tank and the eddy current separator.

[0010] In a preferred embodiment, spring seats are provided at the four bottom corners of the vibration groove, and a frame is provided at the bottom of the spring seats.

[0011] In a preferred embodiment, a plurality of spring rods are provided on the bottom inner wall of the vibrating trough, and the spring rods are slidably connected to the screening trough.

[0012] In a preferred embodiment, a flow divider is provided at the output end of the screening tank, and the flow divider is located at the junction area of ​​the inclined plate and the horizontal plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model is designed to simultaneously move a screening trough up and down within the vibrating trough while it vibrates, and is combined with an inclined plate and a magnetic suction plate corresponding to the position of the inclined plate. By using the buoyancy of water and the attraction of the magnetic suction plate, concrete fragments containing ferromagnetic metal waste such as iron wire can be screened out.

[0015] Furthermore, since the screening tank causes the concrete fragments moving on its surface to be repeatedly immersed in the water layer in the vibrating tank, and with the continuous spraying and rinsing from the cleaning pipe, the combination of the two cleaning methods can more thoroughly clean the sludge and other impurities attached to the concrete fragments, thereby significantly improving the quality of the recycled aggregate product.

[0016] Furthermore, by using an eddy current separator, concrete fragments containing non-ferromagnetic metals can be further separated from pure concrete fragments, thereby further improving the purity of the concrete fragments and increasing resource recycling efficiency.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] The concrete fragments in this invention are 5 to 10 mm in diameter. In concrete fragments containing ferromagnetic metal waste such as iron wire, most of the metal waste is completely encased, while a small portion of the metal waste is exposed. Therefore, traditional magnetic adsorption devices cannot directly adsorb them.

[0026] Example 1

[0027] Refer to the instruction manual appendix Figures 1 to 6 This utility model proposes a recycled aggregate processing equipment for concrete preparation to solve the problem that the magnetic suction equipment on the existing screening device is difficult to screen out concrete fragments containing ferromagnetic metal waste such as iron wire; it includes: a cleaning mechanism 2, the cleaning mechanism 2 includes a vibration tank 21, a vibration motor 22 is provided on the vibration tank 21 to drive the vibration tank 21 to generate vibration, and the output end of the vibration tank 21 is inclined downward.

[0028] It should be noted that recycled aggregate can be fed from the input end of the vibrating trough 21 via a conveyor belt or other conveying device (not shown in the attached diagram), and the length of the vibrating trough 21 can be adjusted according to actual conditions to meet screening requirements.

[0029] A screening mechanism 3 is provided on the vibrating trough 21. The screening mechanism 3 includes a screening trough 31, which is movably disposed in the vibrating trough 21. The output end of the screening trough 31 is inclined downward. Several cleaning pipes 25 are provided on the vibrating trough 21 along the length of the screening trough 31. The cleaning pipes 25 are located above the screening trough 31. A magnetic suction plate 24 is provided on one side of the vibrating trough 21. An inclined plate 34 and a horizontal plate 35 are provided at the bottom of the screening trough 31. The inclined plate 34 is located on the side close to the magnetic suction plate 24.

[0030] It should be noted that the screening tank 31 is similar to the vibration tank 21, and its size can be adjusted according to the actual situation. The cleaning pipe 25 is connected to a water supply device, such as a water pump, which is a mature technology well known to those in the art and will not be described in detail in this embodiment. Several spray pipes are provided on the cleaning pipe 25, and the openings of the spray pipes face the inclined plate 34 and the horizontal plate 35 for continuous rinsing of concrete fragments.

[0031] Furthermore, the continuous spraying of water from the cleaning pipe 25 will accumulate a certain depth of water flow in the vibration tank 21, for example, a water depth of 10cm. The water flow will continuously be discharged from the output end of the vibration tank 21, but will always maintain a certain depth of water layer at the bottom of the vibration tank 21.

[0032] Furthermore, the magnetic suction plate 24 is an electromagnet module, the size and quantity of which can be adjusted according to the actual situation, and the magnetic suction plate 24 is arranged along the length of the screening groove 31.

[0033] In this embodiment, the specific implementation scenario is as follows: starting the vibration motor 22 will drive the vibration tank 21 to vibrate continuously. At the same time, the cleaning pipe 25 will continuously wash the concrete fragments in the screening tank 31. While vibrating with the vibration tank 21, the screening tank 31 will move up and down along the length of the spring rod 32. When the screening tank 31 moves down to the bottom water layer of the vibration tank 21, the buoyancy of the water will cause the concrete fragments to float to a certain height. At this time, the concrete fragments containing ferromagnetic metal waste such as iron wire will float towards the magnetic suction plate 24 due to the magnetism generated by the magnetic suction plate 24. The process is repeated continuously as the concrete fragments move along the length of the screening tank 31. Concrete fragments that do not contain ferromagnetic metal waste such as iron wire will not stay on the inclined plate 34 due to gravity and because they cannot be attracted by the magnetic plate 24. As a result, they are gradually guided to the horizontal plate 35. Finally, concrete fragments containing ferromagnetic metal waste such as iron wire and concrete fragments that do not contain ferromagnetic metal waste will be diverted by the diversion plate 33 at the output end of the screening tank 31 and guided to different collection devices (not shown in the figure), thereby completing the screening of concrete fragments containing ferromagnetic metal waste such as iron wire.

[0034] Furthermore, since the screening tank 31 causes the concrete fragments moving on its surface to be repeatedly immersed in the water layer in the vibrating tank 21, and with the continuous spraying and rinsing from the cleaning pipe 25, the combination of the two cleaning methods can more thoroughly clean the sludge and other impurities attached to the concrete fragments, thereby significantly improving the quality of the recycled aggregate product.

[0035] Example 2

[0036] Based on Example 1, refer to the appendix of the specification. Figures 1 to 6 This utility model provides an eddy current separation device to screen out concrete fragments containing non-ferromagnetic metallic impurities. For example, some concrete fragments containing copper or aluminum wires cannot be attracted by the magnetic plate 24 and will therefore be mixed in with the pure concrete fragments. If these concrete fragments containing non-ferromagnetic metallic impurities are not screened out, it will not only affect the quality of subsequent construction, but also cause a great waste of resources.

[0037] The output end of the screening tank 31 is provided with a sorting mechanism 4. The sorting mechanism 4 includes a vortex sorting cylinder 42 fixedly installed at the bottom of the screening tank 31. A drive assembly 41 is provided on one side of the screening tank 31. The output end of the drive assembly 41 is fixedly connected to the vortex sorting cylinder 42.

[0038] It should be noted that the drive component 41 is a motor used to drive the eddy current sorting cylinder 42. The eddy current sorting cylinder 42 contains an electromagnetic coil. The drive component 41 causes the electromagnetic coil to generate an eddy current effect, that is, to generate a rotating magnetic field near the eddy current sorting cylinder 42. When a conductor such as copper or aluminum enters the rotating magnetic field, a closed eddy current will be induced inside the conductor. The magnetic field generated by the eddy current is opposite to the original magnetic field, causing the conductor to be subjected to a repulsive force, namely the "Lorentz force," which causes its trajectory to deviate from the non-conductive material. This is a well-known and mature technology in the art, and will not be described in detail in this embodiment.

[0039] Furthermore, due to the arrangement of the sorting mechanism 4, when concrete fragments containing non-ferromagnetic metals such as aluminum and copper and pure concrete fragments are about to be discharged from the output end of the screening tank 31, the concrete fragments containing non-ferromagnetic metals will be ejected from the material flow due to eddy current repulsion force and fall into a specific collection device (not shown in the attached figure).

[0040] A baffle 26 is provided at the bottom of the screening tank 31. The baffle 26 is located on the opposite side of the output end of the vibration tank 21 and the eddy current separator 42.

[0041] It should be noted that the baffle 26 is used to prevent sewage from entering the collection device.

[0042] A spring seat 23 is provided at each of the four corners of the bottom of the vibration groove 21, and a frame 1 is provided at the bottom of the spring seat 23.

[0043] It should be noted that a spring is provided on the spring seat 23, and its size and specifications can be adjusted according to the actual situation.

[0044] Several spring rods 32 are provided on the bottom inner wall of the vibration trough 21, and the spring rods 32 are slidably connected to the screening trough 31.

[0045] It should be noted that a spring is installed on the spring rod 32, and its size and specifications can be adjusted according to the actual situation.

[0046] A flow divider plate 33 is provided at the output end of the screening tank 31. The flow divider plate 33 is located at the junction area of ​​the inclined plate 34 and the horizontal plate 35.

[0047] It should be noted that the installation position and size of the diverter plate 33 can be adjusted according to the actual situation. This is a mature technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0048] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
