Description

Technical Field

[0001] This utility model relates to the field of recycled concrete technology, specifically to a sand and gravel separation device for processing recycled concrete. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing, washing, and grading waste concrete blocks, mixing them with aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel, and then adding cement and water. Recycled concrete aggregates refer to waste concrete blocks, brick slag, and other materials that have been crushed, washed, and graded. In the process of reusing aggregates, separation devices are needed. The aggregate separation device is mainly used to separate sand and stone mixed together. It can separate the smaller sand particles from the larger stone particles for subsequent processing and use.

[0003] Traditional sand and gravel separation devices, while capable of separating sand and gravel, have some shortcomings. For example, the aperture of their separation screens is relatively fixed, and they can only screen a single specification. Therefore, it is difficult to adjust the screening specification according to actual needs, which will cause certain limitations in use. Therefore, in order to address the above problems, a sand and gravel separation device for processing recycled concrete is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a device for separating sand and gravel in the process of recycled concrete. The aperture of its separating screen is relatively flexible and can screen various specifications. Therefore, the screening specifications can be adjusted according to actual needs, so as not to cause limitations in use, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for separating aggregates from recycled concrete includes a pair of symmetrically arranged support bases. A separation cylinder is fixedly connected between the support bases. A feed chute is fixedly connected and communicates with the top center of the separation cylinder. A drive motor is fixedly connected to the outer wall of one of the support bases. A drive shaft is fixedly connected to the output end of the drive motor. The end of the drive shaft away from the drive motor extends into the separation cylinder and is rotatably connected to the inner wall of the separation cylinder. Multiple sets of stirring blades are arranged and fixedly connected at equal intervals on the drive shaft. Multiple sets of separation screen holes are arranged at equal intervals at the bottom of the separation cylinder. Multiple sets of sealing baffles are provided at the bottom of the separation cylinder. Multiple sealing components are provided on the top of the sealing baffles.

[0007] Preferably, each group of separation screen holes consists of three rows, with the aperture of the three rows of separation screen holes distributed in a progressive manner from large to small. Each group has three sealing strips, which correspond to the positions of the separation screen holes in each row. The number of sealing components on each sealing strip is the same as the number of separation screen holes in each row, and their specifications match.

[0008] Preferably, the sealing assembly includes a connecting post fixedly connected to the top of the sealing strip, a connecting seat is provided above the connecting post, a rubber clip is fixedly connected to the top of the connecting seat, and positioning springs are symmetrically and fixedly connected to the bottom of the connecting seat.

[0009] Preferably, the top of the connecting column is symmetrically provided with positioning slots, the positioning slots and the positioning spring are positioned correspondingly and matched in specifications, and the outer side of the connecting seat is rotatably connected with a rotating sleeve.

[0010] Preferably, the bottom of the inner wall of the rotating sleeve is provided with an internal thread, and the top of the outer wall of the connecting column is fixedly connected with an external thread, wherein the internal thread and the external thread are configured to match each other in terms of specifications.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the support base provides good support and structural stability for the separation cylinder, while the separation cylinder provides separation space for sand and gravel. The feed chute guides the sand and gravel into the separation cylinder, and the drive motor, transmission shaft, and stirring blades agitate the sand and gravel entering the separation cylinder. This not only prevents the sand and gravel from clumping but also improves their fluidity within the separation cylinder, thereby increasing the separation efficiency. The separation screen holes allow for screening, enabling smaller sand particles to pass through and be discharged from the separation cylinder, while larger stones are blocked and retained within the separation cylinder for subsequent processing and use. The sealing strips and sealing components can block the separation screen holes, and multiple screening specifications can be achieved by opening and closing different sizes of separation screen holes. Therefore, the screening specifications can be adjusted according to actual needs, thus avoiding limitations in use. Attached Figure Description

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A device for separating aggregates from recycled concrete includes a pair of symmetrically arranged support bases 1, a separation cylinder 2 fixedly connected between the support bases 1, a feed chute 3 fixedly connected and connected to the top center of the separation cylinder 2, a drive motor 4 fixedly connected to the outer wall of one support base 1, a drive shaft 5 fixedly connected to the output end of the drive motor 4, the end of the drive shaft 5 away from the drive motor 4 extending into the separation cylinder 2 and rotatably connected to the inner wall of the separation cylinder 2, multiple sets of stirring blades 6 arranged and fixedly connected at equal intervals on the drive shaft 5, multiple sets of separation screen holes 7 arranged at equal intervals at the bottom of the separation cylinder 2, multiple sets of sealing baffles 8 provided at the bottom of the separation cylinder 2, and multiple sealing components 9 provided at the top of the sealing baffles 8.

[0025] Each set of separation screen holes 7 consists of three rows, with the hole diameters of the three rows of separation screen holes 7 arranged in a progressive manner from large to small. Each set of sealing strips 8 consists of three strips, corresponding to the positions of each row of separation screen holes 7. The number of sealing components 9 on each sealing strip 8 is the same as the number of separation screen holes 7 in each row, and their specifications match. The sealing strips 8 and sealing components 9 can seal and unseal the separation screen holes 7 according to actual needs. The sealing component 9 includes a connecting post 901 fixedly connected to the top of the sealing strip 8, a connecting seat 902 above the connecting post 901, a rubber clamp 903 fixedly connected to the top of the connecting seat 902, and positioning springs 9 symmetrically and fixedly connected to the bottom of the connecting seat 902. 04. The top of the connecting column 901 is symmetrically provided with positioning slots 905. The positioning slots 905 and the positioning spring 904 are positioned and matched in specifications. The outer side of the connecting seat 902 is rotatably connected with a rotating sleeve 906. The bottom of the inner wall of the rotating sleeve 906 is provided with an internal thread 907. The top of the outer wall of the connecting column 901 is fixedly connected with an external thread 908. The internal thread 907 and the external thread 908 are matched in specifications. The sealing component 9 can block the separation screen hole 7 and can achieve multi-specification screening by releasing the separation screen hole 7 of different specifications. Therefore, the screening specifications can be adjusted according to actual needs, so as not to cause limitations in use.

[0026] Workflow: First, power on all electrical appliances and connect them to external controllers. Under normal conditions, all separation screen holes 7 are blocked by the corresponding sealing components 9 on the sealing baffles 8. During sand and gravel separation, sand and gravel are first introduced into the separation cylinder 2 between the support bases 1 through the feed chute 3. Then, according to the actual separation requirements, the sealing components 9 blocking the separation screen holes 7 of the corresponding specifications are pulled out through the sealing baffles 8. The pulled-out sealing components 9 will unblock the separation screen holes 7 of this specification, thus enabling sand and gravel separation using the separation screen holes 7 of this specification. For example, when the smallest specification separation is required, simply pull out the sealing components 9 inserted in the row with the smallest hole diameter in each group of separation screen holes 7 through the sealing baffles 8. At this time, the remaining two rows in each group will be unblocked. The separation screen holes 7 are still blocked by the corresponding specification of the sealing component 9. The separation cylinder 2 can only separate through the smallest diameter separation screen hole 7. The separation of other specifications is the same. After the separation screen hole 7 of the appropriate specification is unblocked, the drive motor 4 is started. The drive motor 4 will drive the transmission shaft 5 and the stirring blades 6 on it to rotate. The stirring blades 6 will stir the sand and gravel, which can not only prevent the sand and gravel from agglomerating, but also improve the flowability of the sand and gravel in the separation cylinder 2, thereby improving the separation efficiency of sand and gravel. The unblocked separation screen hole 7 can screen the sand and gravel, allowing the smaller sand particles to pass through and be discharged from the separation cylinder 2 for collection, while blocking the larger stone particles and keeping them in the separation cylinder 2. Finally, the separation can be opened. The cylinder cover on the front wall of cylinder 2 guides the stone inside out. The sealing strip 8 is made of rubber or other materials with a certain deformation capacity. During sealing, the sealing strip 8 is first placed below the separating cylinder 2, and the sealing components 9 on it are inserted one by one into the corresponding size of the separating screen holes 7. The rubber clamps 903 in the sealing components 9 will deform due to compression when passing through the separating screen holes 7. When the connecting column 901 is fully inserted into the separating screen hole 7, the rubber clamps 903 are also fully inserted into the separating cylinder 2. At this time, the squeezing pressure of the separating screen hole 7 on the rubber clamps 903 disappears, and the rubber clamps 903 will spring back and thus be locked in the separating screen hole 7. It can be removed by simply pulling it out with force. Because the rubber clamps 903 have a flexible structure, when it To facilitate replacement in case of damage, the rubber clamp 903 is first placed above the connecting post 901 during installation. The positioning spring 904 at the bottom of the connecting seat 902 is then lowered and inserted into the positioning slot 905 for positioning, aligning the connecting seat 902 and the rotating sleeve 906 with the connecting post 901. When the connecting seat 902 moves down until the rotating sleeve 906 contacts the external thread 908, it will be obstructed and unable to move further. At this point, rotating the rotating sleeve 906 causes it to rotate downwards through the engagement of the internal thread 907 and the external thread 908, simultaneously lowering the positioning spring 904. As the rotating sleeve 906 rotates downwards, the connecting seat 902, due to the positioning of the positioning spring 904, will not rotate with the rotating sleeve 906, but will only move downwards synchronously.The connecting seat 902 is ultimately threadedly connected to the connecting post 901 via the rotating sleeve 906, internal thread 907, and external thread 908; disassembly follows the same procedure.
