Description

Technical Field

[0001] The present invention relates to the technical field of waste concrete processing, and more specifically, to a comprehensive treatment device and process for converting waste concrete into building materials. Background Art

[0002] Concrete refers to a general term for engineering composite materials that bond aggregates into a whole by cementitious materials and is widely used in civil engineering. In the processing of concrete raw materials, stones need to be crushed to obtain the fine stone aggregates required for production. A relatively common method is to use a jaw crusher to crush the stones.

[0003] In the patent "CN202010402858.6", a jaw crusher for concrete production is proposed, including a frame. A first side plate is fixedly connected to the side wall of the frame. A conical channel is formed between the first side plate and the second side plate. A fixed jaw plate is fixedly connected to the side wall of the first side plate. A flywheel is rotatably connected to the side wall of the frame. The output shaft of the flywheel penetrates the outer wall of the frame and is rotatably connected to the second side plate. A moving jaw is fixedly connected to the side of the second side plate close to the fixed jaw plate through a fixing mechanism. Crushing teeth are evenly distributed on the side wall of the moving jaw. A tightening device for pressing against the second side plate is arranged on the inner wall of the frame. A turning mechanism for turning the stones in the conical channel is installed on the inner wall of the frame. In this patent, crushing teeth are evenly distributed on the side wall of the moving jaw, and the fixed jaw plate is provided with crushing teeth, which will cause the concrete near the fixed jaw plate to slide up along the outer wall of the fixed jaw plate, resulting in waste of a part of the kinetic energy. Even for some relatively smooth concrete, there will be slipping even with crushing teeth, which will also cause waste of a part of the kinetic energy.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a comprehensive treatment device and process for converting waste concrete into building materials, in order to achieve a more practical value purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a comprehensive treatment device and process for converting waste concrete into building materials to solve the above problems.

[0006] The purpose and efficacy of the portable anesthetic clinical injection device of the present invention are achieved by the following specific technical means:

[0007] A comprehensive treatment device and process for converting waste concrete into building materials, including a box body of a crushing device. A feed hopper is fixedly arranged at the upper end of the box body. A crushing assembly is installed inside the box body. A first baffle for cooperating with the crushing assembly is slidably arranged on the inner wall of the box body. A discharging device for cooperating with the crushing assembly is installed at the lower end of the box body;

[0008] The described crushing assembly includes a pressing plate. A rotating shaft is rotatably installed at the middle position of the pressing plate. A connecting rod is installed at the middle position of the rotating shaft. A turntable is hingedly arranged at the end of the connecting rod. A rotating rod is fixedly installed at the central axis position of the turntable. One end of the rotating rod is connected to the output shaft of the motor. A main shaft is fixedly installed at the lower end of the pressing plate. The main shaft penetrates through both sides of the box body and is rotatably connected thereto. Gears are respectively fixedly arranged at both ends of the main shaft. Rack teeth for cooperating with the gears are fixedly connected to both side walls of the first baffle. A crushing plate is installed on the outer wall of the pressing plate by bolts. Crushing strips are fixedly arranged on the outer wall of the crushing plate;

[0009] In practical applications, when it is necessary to crush waste concrete, the motor starts to work. The output shaft of the motor drives the rotating rod to rotate. The rotating rod drives the turntable to rotate. The turntable drives the connecting rod to move, and then drives the pressing plate to swing. Thus, the pressing plate cooperates with the first baffle to crush the waste concrete. At the same time, when the pressing plate exerts pressure, the pressing plate drives the main shaft to rotate. The main shaft drives the gear to rotate. The gear drives the rack teeth to move downward. The convex strips on the outer wall of the first baffle drive the concrete to fall. Moreover, the convex strips increase in sequence, so that it can effectively prevent the concrete from surging upward, thereby improving the crushing efficiency.

[0010] Furthermore, the discharging device includes a discharging hopper. A filter plate is fixedly arranged at the middle position of the discharging hopper. Flow guiding plates are mirror-installed on the outer walls of the discharging hopper and the filter plate. A return spring is installed between the lower end of the discharging hopper and the box body. Vibration assemblies for cooperating with the rack teeth are respectively installed on both sides of the discharging hopper. The vibration assembly includes a fixing plate fixed to the outer wall of the discharging hopper. A roller is rotatably installed at the upper end of the fixing plate;

[0011] In practical applications, when the crushed concrete falls onto the upper end of the filter plate, the crushed stones will fall to the bottom of the discharging hopper, while the steel bars and larger crushed concrete will fall along the filter plate. At the same time, when the rack teeth move up and down, the roller will roll along the outer wall of the rack teeth, so that the roller will generate vibration. The roller drives the discharging hopper to vibrate through the fixing plate, so that the crushed concrete will fall along the discharging hopper.

[0012] Furthermore, balls are rotatably arranged on the back surface of the first baffle. Multiple convex strips for cooperating with the crushing assembly are fixedly arranged on the other half of the first baffle. The convex strips increase in sequence from bottom to top. The first baffle is slidably connected to the box body. A connecting block is fixedly arranged between the first baffle and the rack teeth. A sliding groove for cooperating with the connecting block is opened on the outer wall of the box body.

[0013] Furthermore, a second baffle is fixedly arranged at the upper end of the box body at one end of the discharging hopper;

[0014] In practical applications, the second baffle is used to prevent crushed stones from falling between the box body and the feeding hopper.

[0015] Furthermore, a dust baffle is hingedly arranged at the lower end of the feeding hopper inside the box body, and a first torsion spring is installed at the hinge of the dust baffle;

[0016] In practical applications, the dust baffle is used to prevent broken dust and crushed stones from splashing outside the box body.

[0017] Furthermore, the comprehensive treatment process for recycling waste concrete building materials includes the following steps:

[0018] First step, material crushing: Put waste concrete blocks into the waste concrete block treatment device and carry out crushing treatment on the waste concrete blocks;

[0019] Second step, raw material preparation: Prepare the cement, sand and binder raw materials according to the appropriate raw material ratio for configuration treatment;

[0020] Third step, raw material mixing: The cement, sand and binder raw materials after the ratio treatment in the second step are mixed with water and placed in a mixing container for mixing treatment;

[0021] Fourth step, raw material forming: The mixed and stirred raw materials are densely formed and cured to form the required concrete.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When it is necessary to crush waste concrete, the motor starts to work. The output shaft of the motor drives the rotating rod to rotate, the rotating rod drives the turntable to rotate, the turntable drives the connecting rod to move, and then drives the pressing plate to swing. Thus, the pressing plate cooperates with the first baffle to crush the waste concrete. At the same time, when the pressing plate squeezes, the pressing plate drives the main shaft to rotate, the main shaft drives the gear to rotate, the gear drives the rack to move downward, and the convex strips on the outer wall of the first baffle drive the concrete to fall. Moreover, the convex strips increase in sequence, so as to effectively prevent the concrete from surging upward, thereby improving the crushing efficiency.

[0024] 2. When the crushed concrete falls to the upper end of the filter plate, the crushed stones will fall to the bottom of the feeding hopper, while the steel bars and larger crushed concrete fall along the filter plate. At the same time, when the rack moves up and down, the roller will roll along the outer wall of the rack, so that the roller will generate vibration. The roller drives the feeding hopper to vibrate through the fixed plate, so that the crushed concrete will fall along the feeding hopper.

[0025] Other advantages, objectives and features of the present invention will be partially reflected by the following description, and partially will be understood by those skilled in the art through the research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Embodiment:

[0039] As shown in the attached Figure 1 to the attached Figure 7 shown:

[0040] The present invention provides a comprehensive treatment device and process for recycling waste concrete building materials, including a box body 1 of a crushing device. A feed hopper 101 is fixedly arranged at the upper end of the box body 1. A crushing assembly 4 is installed inside the box body 1. A first baffle 3 used in cooperation with the crushing assembly 4 is slidably arranged on the inner wall of the box body 1. A discharging device 2 used in cooperation with the crushing assembly 4 is installed at the lower end of the box body 1;

[0041] The crushing assembly 4 includes an extrusion plate 401. A rotating shaft 402 is rotatably installed at the middle position of the extrusion plate 401. A connecting rod 403 is installed at the middle position of the rotating shaft 402. The end of the connecting rod 403 is hinged with a turntable 404. A rotating rod 405 is fixedly installed at the central axis position of the turntable 404. One end of the rotating rod 405 is connected to the output shaft of the motor. A main shaft 406 is fixedly installed at the lower end of the extrusion plate 401. The main shaft 406 penetrates through both sides of the box body 1 and is rotatably connected thereto. Gears 407 are respectively fixedly arranged at both ends of the main shaft 406. Rack bars 302 used in cooperation with the gears 407 are fixedly connected to both side walls of the first baffle 3. A crushing plate is installed on the outer wall of the extrusion plate 401 through bolts, and crushing strips are fixedly arranged on the outer wall of the crushing plate;

[0042] In actual application, when it is necessary to crush waste concrete, the motor starts to work. The output shaft of the motor drives the rotating rod 405 to rotate. The rotating rod 405 drives the turntable 404 to rotate. The turntable 404 drives the connecting rod 403 to move, and then drives the extrusion plate 401 to swing. Thus, the extrusion plate 401 cooperates with the first baffle 3 to crush the waste concrete. At the same time, when the extrusion of the extrusion plate 401 is completed, the extrusion plate 401 drives the main shaft 406 to rotate. The main shaft 406 drives the gear 407 to rotate. The gear 407 drives the rack bar 302 to move upward. As a result, the crushed stones between the extrusion plate 401 and the first baffle 3 will become loose, thereby preventing the crushed concrete from being stuck at the feeding port and being re-extruded, which may cause the concrete to be extruded into smaller pieces and result in different sizes of the crushed concrete.

[0043] Among them, the discharging device 2 includes a blanking hopper 201. A filter plate 204 is fixedly arranged at the middle position of the blanking hopper 201. Flow guide plates 205 are mirror-installed on the outer walls of the blanking hopper 201 and the filter plate 204. A return spring 206 is installed between the blanking hopper 201 and the lower end of the box body 1. Vibration components for cooperating with the rack 302 are respectively installed on both sides of the blanking hopper 201. The vibration components include a fixing plate 202 fixed to the outer wall of the blanking hopper 201, and a roller 203 is rotatably installed at the upper end of the fixing plate 202;

[0044] In practical applications, when the crushed concrete falls onto the upper end of the filter plate 204, the crushed stones will fall to the bottom of the blanking hopper 201, while the steel bars and larger crushed concrete will fall along the filter plate 204. At the same time, when the rack 302 moves up and down, the roller 203 will roll along the outer wall of the rack 302, so that the roller 203 will generate vibration. The roller 203 drives the blanking hopper 201 to vibrate through the fixing plate 202, so that the crushed concrete will fall along the blanking hopper 201.

[0045] Among them, balls are rotatably arranged on the back surface of the first baffle 3. Multiple convex strips 301 for cooperating with the crushing component 4 are fixedly arranged on the other half of the first baffle 3. The convex strips 301 increase gradually from bottom to top. The first baffle 3 is slidably connected to the box body 1. A connecting block is fixedly arranged between the first baffle 3 and the rack 302. A chute for cooperating with the connecting block is opened on the outer wall of the box body 1.

[0046] Among them, a second baffle 5 is fixedly arranged at the upper end of one end of the box body 1 inside the box body 1;

[0047] In practical applications, the second baffle 5 is used to prevent crushed stones from falling between the box body 1 and the blanking hopper 201.

[0048] Among them, a dust-proof plate 6 is hinged at the lower end of the feed hopper 101 inside the box body 1, and a first torsion spring is installed at the hinge of the dust-proof plate 6;

[0049] In practical applications, the dust-proof plate 6 is used to prevent the crushed dust and crushed stones from splashing to the outside of the box body 1.

[0050] Among them, a comprehensive treatment process for recycling waste concrete building materials includes the following steps:

[0051] The first step, material crushing: Put the waste concrete blocks into the waste concrete block treatment device and perform crushing treatment on the waste concrete blocks;

[0052] The second step, raw material preparation: Prepare the raw materials of cement, sand and binder according to the appropriate raw material ratio for configuration treatment;

[0053] Step 3: Mixing of raw materials: The cement, sand, and binder raw materials after the proportioning treatment in the second step are mixed with water and placed in a mixing container for mixing treatment.

[0054] Specific usage method and function of this embodiment:

[0055] When it is necessary to crush waste concrete, the motor starts to work. The output shaft of the motor drives the rotating rod 405 to rotate. The rotating rod 405 drives the turntable 404 to rotate. The turntable 404 drives the connecting rod 403 to move, and then drives the pressing plate 401 to swing. Thus, the pressing plate 401 cooperates with the first baffle 3 to crush the waste concrete. At the same time, when the pressing plate 401 is pressing, the pressing plate 401 drives the main shaft 406 to rotate. The main shaft 406 drives the gear 407 to rotate. The gear 407 drives the rack 302 to move downward. The convex strip 301 on the outer wall of the first baffle 3 drives the concrete to fall. Moreover, the convex strip 301 increases in sequence, so that it can effectively prevent the concrete from surging upward, thereby improving the crushing efficiency.

[0056] When the crushed concrete falls to the upper end of the filter plate 204, the crushed stones will fall to the bottom of the feeding hopper 201, while the steel bars and larger crushed concrete will fall along the filter plate 204. At the same time, when the rack 302 moves up and down, the roller 203 will roll along the outer wall of the rack 302. Thus, the roller 203 will generate vibration. The roller 203 drives the feeding hopper 201 to vibrate through the fixing plate 202. Thus, the crushed concrete will fall along the feeding hopper 201.

[0057] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
