Description

Technical Field

[0001] This application relates to the field of concrete recycling, and more specifically, to a device for recycling concrete waste from mines. Background Technology

[0002] Mining concrete waste recycling equipment is a specialized system for processing waste concrete generated during mining and related engineering projects. It typically uses core processes such as crushing and screening to break down concrete blocks into reusable coarse and fine aggregates, providing recycled building materials for construction, infrastructure, and other fields, thus meeting the needs of green mining construction.

[0003] In response, Chinese patent application number 202322189703.0 discloses a concrete waste recycling device, relating to the field of concrete recycling technology. The device includes a collection chamber and a crushing chamber, with the crushing chamber mounted on top of the collection chamber. This concrete waste recycling device, through the coordinated use of a screening plate, a vibrating motor, an electric push rod, and a push plate, allows the waste material crushed by the crushing roller to fall onto the screening plate. The vibrating motor at the bottom of the screening plate operates, causing the screening plate to shake and screen the crushed waste. Waste material meeting recycling requirements falls into the inner side of the collection chamber, while larger pieces that cannot be screened are discharged through the end of the screening plate. The screened waste accumulates in the collection chamber. After complete waste recycling, the electric push rod operates, pushing the push plate to slide within the collection chamber, discharging the accumulated waste through a second output port. This allows the concrete waste recycling device to differentiate the crushed waste, ensuring the quality of waste recycling.

[0004] The above solution has the following shortcomings: When in use, by setting a vibrating screen plate at the bottom, the crushed waste can be separated after vibration, which improves the recycling quality. However, because the waste will accumulate in layers when it falls, the vibration method has a small range of motion, and some small particles of waste will remain in the interlayer and cannot be separated. Therefore, it needs to be improved. Utility Model Content

[0005] To overcome the above deficiencies, this application provides a mining concrete waste recycling device.

[0006] This application provides a mining concrete waste recycling device, including a movable base and a first support and a second support fixed to its top. A crushing box is fixedly installed on the top of the first support, and a separation box is fixedly installed on the top of the second support. The crushing box and the separation box are connected to each other, and a rotatable screening barrel is provided inside the separation box.

[0007] In one specific implementation, the screening barrel is designed with openings at both ends, and a turntable is provided on the surface of one end of the screening barrel, and the other side of the turntable is rotatably connected to the inner wall of the separation box, wherein the other end of the screening barrel is provided with a perforated connecting plate.

[0008] In the above process, the openings at both ends of the screening barrel allow for the feeding of crushed waste material and the discharge of coarse aggregate.

[0009] In one specific implementation, the surface of the screening barrel is designed with a hollowed-out shape, and a screen is fixed to the hollowed-out surface.

[0010] In the above process, the crushed waste material tumbles inside the drum, and the fine aggregate that meets the particle size requirements falls through the mesh of the screen into the bottom of the separation box, thus achieving the screening of coarse and fine aggregates.

[0011] In one specific implementation, the crushing box is provided with a feed inlet at the top and a guide hopper at the bottom, wherein a guide pipe is provided between the guide hopper and the separation box, and one end of the guide pipe extends into the opening of the screening barrel near the turntable.

[0012] In the above process, it is convenient to transport the crushed waste material into the screening tank.

[0013] In one specific implementation, the feed tube extends into the screening barrel and has a bushing on one end surface, wherein the bushing rotates within the screening barrel and the inner wall of its adjacent opening.

[0014] In the above process, the bushing extending from one end of the guide pipe into the screening barrel can rotate on the inner wall of the adjacent opening of the screening barrel. This does not affect the normal rotation and screening action of the screening barrel, but also seals and limits the connection between the guide pipe and the screening barrel, preventing waste from leaking out from the gap between them. At the same time, it reduces frictional wear between the guide pipe and the screening barrel, and extends the service life of the components.

[0015] In one specific implementation, a connecting bracket is fixedly connected to the surface of the feed tube, wherein a mounting plate is provided on the side wall of the connecting bracket, and a vibration motor is fixed to the surface of the mounting plate.

[0016] In the above process, the high-frequency vibration generated by the vibrating motor makes the crushed waste in the feed pipe less likely to accumulate and block, ensuring that the waste can be smoothly transported to the screening bucket and ensuring the continuity of material transmission.

[0017] In one specific implementation, a discharge box is fixedly connected to the side of the separation box away from the feed pipe, wherein the diameter of the discharge box is the same as that of the perforated connecting plate.

[0018] In the above process, it is easy to guide the coarse aggregate into the feeding box, realize the directional collection of coarse aggregate, and avoid mixing with fine aggregate.

[0019] In one specific implementation, a cylinder is fixed to the outer end of the feeding box, and a telescopic rod is provided on one side of the cylinder. The telescopic rod extends into the feeding box, and a flipping motor is fixed to the telescopic end of the telescopic rod. A baffle is fixed to the output end of the flipping motor. The diameter of the baffle is the same as the diameter of the perforated connecting plate, and the baffle is attached to one side of the perforated connecting plate.

[0020] In the above process, the extension and retraction of the telescopic rod drives the tilting motor and the baffle to move, so as to achieve the contact or separation of the baffle and the perforated connecting plate. When in contact, the baffle seals the perforated connecting plate to ensure that the waste in the screening barrel is fully screened. After screening, the telescopic rod retracts to drive the baffle to detach, and at the same time the tilting motor drives the baffle to rotate, which can help drive the screening barrel to rotate so that the coarse aggregate enters the feeding box.

[0021] In one specific implementation, the side of the baffle away from the tilting motor is provided with a connecting pin that matches the perforated connecting plate, wherein the connecting pin is inserted into the perforated connecting plate and the length of the connecting pin is greater than the length of the feeding box.

[0022] In the above process, when the baffle is driven to rotate by the flip motor, the connecting pin can drive the perforated connecting plate and the screening barrel to rotate, and perform flip screening.

[0023] In one specific implementation, the bottom of the separation box is provided with a fine aggregate discharge port, and the bottom of the feeding box is provided with a coarse aggregate discharge port.

[0024] In the above process, coarse and fine aggregates are completely separated during recycling through two independent discharge outlets, which facilitates subsequent separate processing and improves the recycling rate of waste materials.

[0025] Compared with the prior art, the beneficial effects of this application are as follows: the rotatable screening bucket allows the waste material to tumble 360°, which, combined with the baffle sealing and the flipping motor drive, reduces the residue of small particles in the interlayer, achieves efficient separation of coarse and fine aggregates, ensures recycling quality, the guide pipe is equipped with a vibration motor to prevent blockage, and the bushing at the connection not only seals against leakage but also reduces friction, avoiding downtime, reducing losses, and improving the operating efficiency and stability of the device.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Please see Figure 1-8 This application provides a mining concrete waste recycling device, including a movable base 1 made of thickened steel plate welded together and equipped with wear-resistant casters at the bottom. The casters are equipped with a braking locking mechanism, which facilitates the flexible transfer and fixation of the device in the mining operation site. A first bracket 11 and a second bracket 12 are symmetrically fixed to the top of the base 1 by bolts. Both are frame structures made of square tube welded together. A horizontal load-bearing plate is welded to the top of the brackets to fix the crushing box 2 and the separation box 4 respectively, ensuring the stability and impact resistance of the overall support structure.

[0031] The crushing box 2 is fixedly installed on the top of the first support 11 by bolts. The box is equipped with intermeshing crushing toothed rollers, which can crush large pieces of mining concrete waste to a preset particle size. The top of the crushing box 2 is equipped with a flared feed port, and the bottom is welded with a funnel-shaped guide hopper 3. The discharge port of the guide hopper 3 is connected to one end of the guide pipe 31 by a flange. The guide pipe 31 is made of seamless steel pipe, and the outside of the pipe body is welded with reinforcing ribs. Its other end extends into the opening of the screening barrel 44 near the turntable. The length of the extension section is about 1 / 6 of the total length of the screening barrel 44, ensuring that the crushed waste can fall accurately into the screening barrel 44 and avoid spillage during the transmission process.

[0032] A copper bushing is nested on one end of the feed pipe 31 that extends into the screening barrel 44. The outer circumference of the bushing is precision-polished, which not only does not hinder the normal rotation of the screening barrel 44, but also allows the sliding friction of the bushing to replace the direct contact between the feed pipe 31 and the screening barrel 44, reducing component wear. At the same time, a sealing ring is provided between the bushing and the inner wall of the opening of the screening barrel 44, which can effectively prevent crushed waste from leaking out from the gap between them, ensuring the cleanliness of the separation box 4. A connecting bracket 32 ​​is welded to the middle surface of the feed pipe 31. The connecting bracket 32 ​​is formed by stamping steel plate, and a horizontal mounting plate 33 is welded to the side wall. The mounting plate 33 has a waist-shaped mounting hole on its surface. The vibration motor 34 is fixed to the mounting hole by bolts. The vibrating motor 34 is covered with a dustproof cover. The high-frequency vibration generated during operation is transmitted to the feed pipe 31 through the mounting plate 33 and the connecting bracket 32, so that the crushed waste in the pipe is in a state of slight vibration, avoiding blockage of the feed pipe 31 due to waste agglomeration, and ensuring the continuity of material transmission.

[0033] The top of the second support 12 is fixedly installed with a separation box 4 by bolts. The side of the separation box 4 away from the guide pipe 31 is fixedly connected with a feeding box 41 by bolts. The diameter of its feed end is exactly the same as the diameter of the perforated connecting plate 46, ensuring that all the coarse aggregate after screening can enter the feeding box 41 and avoid mixing with the fine aggregate. A flange is welded to the outer end of the feeding box 41. The cylinder 5 is fixed to the flange by bolts. The cylinder body of the cylinder 5 is wrapped with a dust cover to prevent dust in mining operations from entering the cylinder and affecting its extension and contraction performance.

[0034] A telescopic rod 51 is provided on one side of the cylinder 5. The telescopic rod 51 penetrates the side wall of the feeding box 41 and extends into the interior. A sealing guide sleeve is provided at the penetration point to ensure that the telescopic rod 51 can extend and retract flexibly while preventing dust leakage. The telescopic end of the telescopic rod 51 is fixed to a tilting motor 52 by a coupling. The tilting motor 52 is equipped with a waterproof and dustproof shell to adapt to the humid and dusty working environment of the mine. The output end of the tilting motor 52 is fixed to a baffle 53 by a key connection. The baffle 53 is a circular steel plate with a rubber sealing gasket attached to its surface. Its diameter is the same as that of the perforated connecting plate 46. In its natural state, the baffle 53 is tightly fitted to one side of the perforated connecting plate 46 by the rubber sealing gasket, thereby sealing the end of the screening barrel 44. A series of connecting pins 54 are welded to the side of the baffle 53 away from the flipping motor 52. The connecting pins 54 are cylindrical with hard chrome plating. Their diameter matches the hole diameter of the perforated connecting plate 46, and their length is about 5cm longer than the length of the feeding box 41. When the baffle 53 is attached to or not attached to the perforated connecting plate 46, the connecting pins 54 are inserted into the hole of the perforated connecting plate 46 to enhance the stability of the connection between the two.

[0035] The crushing box 2 and the separation box 4 are interconnected via a feed pipe 31. The separation box 4 contains a rotatable screening barrel 44, a cylindrical structure open at both ends, made of rolled stainless steel mesh. The barrel surface is perforated, and a detachable screen 45 is bolted to the perforations. The screen 45 can be selected with different mesh sizes according to recycling needs, facilitating subsequent replacement and maintenance. A circular turntable is welded to one end of the screening barrel 44. The central shaft of the turntable is rotatably connected to the inner wall of the separation box 4 via a bearing. A dust cover is provided on the outside of the bearing to ensure smooth rotation of the screening barrel 44 by the turntable. A perforated connecting plate 46 is welded to the other end of the screening barrel 44. Multiple circular holes are evenly distributed on the surface of the connecting plate to facilitate the smooth discharge of coarse aggregate.

[0036] The bottom of the separation box 4 is provided with an inclined fine aggregate discharge port 43, and the bottom of the feeding box 41 is provided with a vertically downward coarse aggregate discharge port 42. The coarse and fine aggregates are completely separated through independent discharge paths, thereby improving the recycling rate of mine concrete waste.

[0037] The working principle of this mining concrete waste recycling device is as follows: When the device is in operation, it is first moved to the working position and fixed by the wear-resistant universal wheels with a braking locking mechanism at the bottom of the base 1. Mining concrete waste is fed into the flared inlet at the top of the crushing box 2. After being crushed to a preset particle size by the intermeshing crushing rollers inside the box, it falls into the bottom funnel-shaped guide hopper 3. Then, it is conveyed through the flange-connected guide pipe 31 to the opening near the turntable end of the screening barrel 44. The copper bushing at the extended end of the guide pipe 31 rotates within the opening of the screening barrel 44, without affecting the normal rotation of the screening barrel 44 and preventing waste leakage. Simultaneously, the vibration motor 34 drives the guide pipe 31 to vibrate at high frequency through the connecting bracket 32 ​​and mounting plate 33, preventing the waste inside the pipe from accumulating and clogging. After crushing... After the waste material enters the screening barrel 44 inside the separation box 4, the screening barrel 44 rotates smoothly through the central shaft of the turntable at one end. The detachable screen 45 at the hollow part of the barrel screens the waste material. Fine aggregate that meets the particle size falls through the screen 45 into the bottom of the separation box 4 and is discharged through the inclined fine aggregate discharge port 43. The coarse aggregate remaining after screening stays in the screening barrel 44. At this time, the cylinder 5 drives the telescopic rod 51 to extend and retract, driving the tilting motor 52 and the baffle 53 to move. The baffle 53 is attached to the perforated connecting plate 46 through the surface rubber sealing gasket. The tilting motor 52 drives the baffle 53 to rotate the screening barrel 44, pushing the coarse aggregate to the feeding box 41, and finally discharged from the vertical coarse aggregate discharge port 42, realizing the crushing of mining concrete waste and the separation and recycling of coarse and fine aggregates.

[0038] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
