Abstract
Description
Technical Field
[0001] This utility model relates to the field of processing equipment technology, and in particular to a pre-treatment equipment for recycled aggregates. Background Technology
[0002] Recycled aggregate refers to small-particle recycled aggregate made from fill soil that has undergone several screening and processing steps by machinery. The production process involves first using a coarse jaw crusher to break the fill soil into smaller particles, then using a screening machine to remove unqualified products, and simultaneously using a cleaning device to clean the particles. The coarse jaw crusher, screening machine, and cleaning device used in this process can all be considered as recycled aggregate pretreatment equipment.
[0003] Chinese Patent CN220697380U discloses a pre-treatment device for recycled aggregates, including a screening and processing device with a U-shaped outer shell. Multiple metal rings are arranged sequentially inside the U-shaped outer shell. The inner walls of the metal rings are connected to inner metal rings via roller bearings. A screening frame assembly A is located in front of every two inner metal rings, and a screening frame assembly B is located behind every two inner metal rings. A transmission shaft is located on the inner side of each inner metal ring, and a first connecting rod penetrating all the inner metal rings is located at the top, bottom, front, and back of the transmission shaft. This invention improves the convenience of the equipment by dividing the original screening frame into multiple screening frame assemblies A and B. If a particular screening frame assembly A or B deforms due to impact from stones, it can be replaced individually.
[0004] Because construction waste has a complex composition, recycled aggregates are often mixed with various types of construction waste. If these construction wastes are added to the pretreatment equipment at the same time as the recycled aggregates, it will result in low slag discharge efficiency of the pretreatment equipment, affecting the quality of the recycled aggregates. At the same time, it will cause wear and damage to the pretreatment equipment during operation, reducing its stability and affecting production efficiency and the output of recycled aggregates.

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0026] Example 1
[0027] like Figure 1 - Figure 5As shown, the present invention proposes a pretreatment device for recycled aggregate, comprising: a screening frame a1, an installation component 2, and an insertion plate 3; the screening frame a1 is connected to installation blocks a101 at both ends and to screening frame b102 respectively; the screening frame a1 and screening frame b102 are connected to form an outer shell for processing recycled aggregate; the outer shell is internally connected to connectors and rotating components; the connectors include outer shell plates 103 connected to both sides of the inner wall of the outer shell, the outer shell plates 103 are connected to vertical plates 104 at both ends, the vertical plates 104 are connected to inner shell plates 105, and the distance between the outer shell plates 103 and the inner shell plates 105 forms an insertion support cavity; the insertion support cavity is movably connected to the insertion plate 3, the inner wall of the insertion plate 3 is connected to an adsorption plate 301 and handles 302 are connected to both ends respectively; the installation component 2 is connected to the periphery of the screening frame a1 and the screening frame b102. By using adsorption plates 301 to adsorb metal waste in the recycled aggregate, and then removing it, the recycled aggregate is screened by starting a rotating screen. This avoids construction metal waste from affecting the recycled aggregate and the treatment effect, improves the slag discharge efficiency of the pretreatment equipment, improves the quality of the recycled aggregate, and at the same time avoids wear and damage to the pretreatment equipment during operation, improves the stability of use, and increases production efficiency and the output of recycled aggregate.
[0028] To further explain, screening frames a1 and b102 have identical structures, both featuring multiple elongated screening openings. Mounting block a101 has mounting holes a and b, which are opposite each other and located on mounting block b, which is connected to screening frame b102. Screening frames a1 and b102 are connected by aligning mounting holes a and b, and then threaded through mounting holes a and b with a nut to install and engage them.
[0029] To further explain, extension blocks 106 are connected to both ends of the inner shell plate 105. The extension blocks 106 are provided with through holes for installation with the mating plate 3. Screws are used to thread the mating plate 3 through the through holes, thereby increasing the stability of the mating plate 3 when it is installed and used.
[0030] Further explanation: The rotating component includes support rods 107 connected to both ends of the vertical plate 104. Support rods 107 are connected to splicing rods 108, and one end of the splicing rod 108 is connected to a motor 109. The driving end of the motor 109 is connected to a rotating shaft 110. A connecting plate is connected to the periphery of the rotating shaft 110, and the connecting plate is connected to a support ring 111. The other end of the splicing rod 108 is connected to a bearing seat, and the bearing seat rotatably connects to one end of the rotating shaft 110. When the motor 109 is started, it causes the rotating shaft 110 to rotate. The rotating shaft 110 rotates the connecting plate, which in turn drives the support ring 111. The support ring 111 is connected to the interior of the outer shell via the support rods 107, achieving the rotation of the outer shell for pre-screening of recycled aggregates.
[0031] Example 2
[0032] like Figure 4 As shown, the present invention proposes a pretreatment device for recycled aggregates. Based on the above embodiments, this embodiment also details the specific components of the installation component 2 and their assembly method.
[0033] Further explanation: Mounting assembly 2 includes a clamping plate a201 connected to mounting block a101 and mounting block b. Clamping plate a201 is connected to clamping plate b202. Clamping plate b202 is hollow inside, with insertion rods 203 connected to both ends. Insertion rods 203 are movably connected to insertion slots, which are located inside both ends of clamping plate a201. Clamping plates a201 and b202 have a U-shaped structure, which facilitates the clamping and installation of mounting blocks a101 and b, and increases the stability of the connection between screening frame a1 and screening frame b102.
[0034] To further explain, clamping plate b202 is movably connected to mounting block a101 and mounting block b, and is secured by a bolt that passes through clamping plate b202, mounting hole a, and mounting hole b, and is rotated and fixed by a nut thread. Clamping plate b202 and clamping plate a201 are installed in the same way. The two ends of insertion rod 203 are detachably connected to clamping plate b202 and clamping plate a201 by tightening bolts. When clamping plate a201 and clamping plate b202 are installed, clamping plate b202 drives insertion rod 203 into insertion slot, and then the applicable length is adjusted according to the connection of the outer shell components, which facilitates the use of additional screening frame a1 and screening frame b102 components.
[0035] The working principle of this utility model is as follows: When using the recycled aggregate pretreatment equipment, firstly, the mounting blocks a101 and b102 of the screening frame a1 and screening frame b102 are connected through the mounting assembly 2, so that the shell of the pretreatment equipment is connected. The screening frame a1 and screening frame b102 both drive the shell plate 103. The shell plate 103 is connected to the inner shell plate 105 through the vertical plate 104, so that the insertion support cavity is connected and formed inside the shell. The operating handle 302 is used to insert the insertion plate 3 into the insertion support cavity, and then the recycled aggregate is added into the shell cavity. The insertion plate 3 internally drives the adsorption plate 301, which magnetically attracts the building metal waste in the recycled aggregate to the insertion plate 3. Then, the insertion plate 3 is removed from the insertion support cavity, and the adsorbed metal material is cleaned off. When there is a lot of building waste in the recycled aggregate, the insertion plate 3 is repeatedly operated to connect and adsorb the building metal waste. After the building metal connection of the recycled aggregate is cleaned, the insertion plate 3 is finally disassembled from the shell. Then, the shell is rotated by the rotating part to achieve the pretreatment of the recycled aggregate.
[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
