Description

Technical Field

[0001] The invention relates to the technical field of permeable bricks, and in particular to a method for preparing an anti-collapse permeable brick. Background Art

[0002] Permeable bricks are a type of building material with good water permeability. They are widely used in the paving of roads, squares, parks, etc. They have the functions of reducing the urban "heat island effect", alleviating rainwater discharge pressure, and improving ground water circulation.

[0003] In the prior art, when the raw materials for permeable bricks are mixed, the raw materials are not added in a certain order, resulting in that different raw materials are not fully integrated during the mixing process, especially some important components, such as cement, aggregates and other additives, are not evenly distributed, resulting in inconsistent strength, permeability and durability of the permeable bricks. In addition, the raw materials are not evenly mixed during the mixing process, resulting in an unstable pore structure, which in turn affects the permeability of the permeable bricks. If some raw materials are not completely mixed, an uneven pore structure will be formed, resulting in poor permeability in some areas, and the advantages of the permeable bricks cannot be fully utilized. Summary of the invention

[0006] Step 2: Screening: Screen out expanded perlite with a particle size diameter of 2-5 mm, polylactic acid particles with a particle size diameter of 1-4 mm, natural gravel with a particle size diameter of 5-10 mm, and polystyrene particles with a particle size diameter of 1-3 mm.

[0007] Step 3: Mixing: Select crushed aggregates with a weight ratio of 30% expanded perlite and 10% polylactic acid particles and add them to the mixing equipment for mixing. After mixing, add crushed aggregates with a weight ratio of 20% natural gravel for mixing, and finally add crushed aggregates with a weight ratio of 10% polystyrene particles for mixing. After the crushed aggregates are mixed, mix in turn with a binder with a weight ratio of 20% inorganic gelling material, a modifier with a weight ratio of 5% superplasticizer, a pigment with a weight ratio of 2% titanium dioxide, and a wetting agent with a weight ratio of 3% water.

[0008] Step 4: Molding: Pour the mixture into the permeable brick mold and fill it evenly through compression molding to ensure uniform pores in the brick body.

[0009] Step 5: Curing: demold the permeable bricks in the mold and perform curing treatment at a temperature range of 20-30°C and a humidity range of 85-95%. After curing for 7-14 days, the permeable bricks are obtained.

Since the deflection gear is engaged with the gear of the fixed ring, the fan plate is driven to deflect through the deflection gear. The spring is fixedly installed with the raw material tank and the circular ring frame respectively, and can be reset after the telescopic rod of the electric push rod is released from contact with the circular ring frame, thereby closing the fan plate.

[0026] Preferably, the mixing device also includes a mixing motor, which is fixedly mounted on the lower surface of the support frame, and a mixing frame is fixedly mounted on the output shaft of the mixing motor, and the outer surface of the mixing frame is rotatably connected to the inner wall of the groove of the mixing tank, and the outer surface of the mixing frame is rotatably connected to a circular plate with a cylindrical pin.

[0029] Through the above technical scheme, the mixing plate is rotatably connected with the mixing frame, and the mixing frame drives the mixing plate to revolve without affecting its self-rotation. When the mixing plate drives the rotating plate fixedly mounted thereon to revolve, the cylindrical pin on the rotating plate meshes with the cylindrical pin on the circular plate, thereby causing the mixing plate to rotate. The outer surfaces of the upper and lower mixing plates are rotatably connected with the synchronous belt through the synchronous wheel, so that they rotate synchronously. The mixing tank is fixedly connected with the discharge pipe with a valve, and the mixed raw materials can enter the storage frame through the discharge pipe.

[0030] The beneficial effects of the present invention are:

[0031] 1. By setting a switching device, the order of adding raw materials is switched. The switching motor drives the switching frame to rotate. The switching frame contacts the outer surface of the rotating frame. There is a square block on the outer surface of the switching frame and a cylinder under the rotating frame. When the switching frame rotates, the square block on the switching frame contacts the cylinder on the rotating frame, thereby driving the rotating frame to rotate. Circular grooves are provided on the raw material tank and the rotating frame. The raw materials in the raw material tank can enter the funnel fixedly connected with the mixing tank below through the circular groove. This solves the problem that when mixing the raw materials of the permeable bricks, the raw materials are not added in a certain order, resulting in different raw materials not being fully integrated during the mixing process, especially some important components, such as cement, aggregates and other additives, are not evenly distributed, resulting in inconsistent strength, permeability and durability of the permeable bricks.

[0032] 2. An opening and closing device is provided to drive the fan plate to open and close. After the telescopic rod of the electric push rod is extended, it contacts the cylindrical frame on the circular ring frame. The telescopic rod continues to extend to drive the circular ring frame to deflect, so as to drive the fan plate to revolve. When the fan plate revolves, it drives the deflection gear to revolve. Since the deflection gear is meshed with the gear of the fixed ring, the fan plate is deflected through the deflection gear. The spring is fixed to the raw material tank and the circular ring frame respectively. After the telescopic rod of the electric push rod is released from contact with the circular ring frame, it can be reset to close the fan plate. This solves the problem that when mixing the raw materials of the permeable bricks, the raw materials are not added in a certain order, resulting in insufficient fusion of different raw materials during the mixing process, especially some important components, such as cement, aggregates and other additives, are not evenly distributed, resulting in inconsistent strength, permeability and durability of the permeable bricks.

[0033] 3. By setting up a mixing device, the raw materials in the mixing tank are mixed, the mixing motor drives the mixing frame to rotate, the mixing frame drives the mixing plate to revolve, and the rotating plate fixedly mounted therewith revolves. Since the cylindrical pin on the rotating plate is meshed with the cylindrical pin on the circular plate, the mixing plate rotates, and the outer surfaces of the upper and lower mixing plates are connected to the synchronous belt through the synchronous wheel to make them rotate synchronously. The mixed raw materials can enter the storage frame through the discharge pipe, and the valve can regulate the flow of the mixed raw materials. The control panel on the trolley is electrically connected to the switching motor, the electric push rod, and the mixing motor to provide centralized operation and adjustment functions, which solves the problem that the raw materials are not evenly mixed during the mixing process, resulting in unstable pore structure, which in turn affects the permeability of the permeable bricks. Some raw materials are not completely mixed to form an uneven pore structure, which makes the permeability of some areas poor, and the technical problem that the advantages of the permeable bricks cannot be fully utilized.

The support plate 3 is rotatably connected to the rotating frame 31, and it is fixed without affecting its rotation, so that the rotating frame 31 can be driven to rotate by the switching frame 22.

[0058] Specifically, in order to allow the raw materials in the raw material tank 4 to enter the funnel 94 fixedly connected to the mixing tank 11 below through the circular groove 41, and mix the raw materials, the outer surface of the switching frame 22 contacts the outer surface of the rotating frame 31, the raw material tank 4 is fixedly mounted on the outer surface of the rotating frame 31, the outer surface of the raw material tank 4 is slidably connected to the inner wall of the groove of the support frame 2, and the outer surface of the raw material tank 4 and the outer surface of the rotating frame 31 are both provided with circular grooves 41, which contact the outer surface of the rotating frame 31 through the switching frame 22. The outer surface of the switching frame 22 has a square block, and there is a cylinder below the rotating frame 31.

[0059] like Figure 7-10 As shown, in order to transport the raw materials in the raw material tank 4 into the mixing tank 11, an opening and closing device is provided. The opening and closing device is located on the outer surface of the trolley 1, and transports the raw materials in the raw material tank 4 into the mixing tank 11. The opening and closing device includes a circular frame 51 and a fan plate 6. The deflection of the circular frame 51 drives the fan plate 6 to open and close.

The mixing frame 81 drives the mixing plate 9 to revolve without affecting its self-rotation. When the mixing plate 9 drives the rotating plate 91 fixedly installed therewith to revolve, the cylindrical pin on the rotating plate 91 is meshed with the cylindrical pin on the circular plate 82, thereby causing the mixing plate 9 to rotate. The outer surfaces of the upper and lower mixing plates 9 are rotatably connected to the synchronous belt 92 through the synchronous wheel, so that they rotate synchronously. The mixing tank 11 is fixedly connected to the discharge pipe 93 with a valve, and the mixed raw materials can enter the storage frame through the discharge pipe 93. The valve can regulate the flow of the mixed raw materials. The funnel 94 fixedly connected to the mixing tank 11 and the rotating frame 31 rotate to switch the raw material tank 4. The circular groove 41 opened on the two will be located above the funnel 94, so that the raw materials can pass through the funnel 94 into the mixing tank 11. At the same time, the raw material tank 4 and the funnel 94 can be made of 304 or 316 stainless steel to prevent the raw materials from sticking. The control panel 95 on the trolley 1 is electrically connected to the switching motor 21, the electric push rod 5, and the mixing motor 8, providing centralized operation and adjustment functions, so that the staff can easily control the operation of the switching motor 21, the electric push rod 5 and the mixing motor 8.

[0066] Working principle: when it is necessary to mix the crushed aggregate, the staff will add the proportioned expanded perlite, polylactic acid particles, natural gravel, and polystyrene particles into the raw material tank 4 in turn. The raw material tank 4 containing the expanded perlite is located above the funnel 94. The staff starts the electric push rod 5 through the control panel 95. The telescopic rod of the electric push rod 5 contacts the cylindrical frame on the annular frame 51 after being extended. The telescopic rod continues to extend to drive the annular frame 51 to deflect, so that the fan plate 6 rotatably connected to the annular frame 51 and the deflection gear 61 fixedly installed on the fan plate 6 revolve, and the deflection gear 61 is meshed with the gear on the fixed ring 7 fixedly installed in the raw material tank 4, thereby driving the fan plate 6 to deflect and expand it. The expanded perlite in the raw material tank 4 enters the funnel 94 through the circular groove 41 provided on the raw material tank 4 and the rotating frame 31, and enters the mixing tank 11 fixedly connected thereto through the funnel 94;

[0067] When the polylactic acid particles need to enter the mixing tank 11, after the telescopic rod of the electric push rod 5 is released from contact with the cylindrical frame on the annular frame 51, the springs 71 fixedly installed with the raw material tank 4 and the annular frame 51 respectively reset it, thereby closing the fan plate 6. At this time, the staff starts the switching motor 21 through the control panel 95 to drive the switching frame 22 to rotate. The outer surface of the switching frame 22 has a square block, and there is a cylinder under the rotating frame 31. When the switching frame 22 rotates, the square block on the switching frame 22 contacts the cylinder on the rotating frame 31, thereby driving the rotating frame 31 rotatably connected to the support plate 3 to rotate. There is a semicircular arc plate on the switching frame 22, which is in sliding contact with the arc groove on the support plate 3. The arc groove has four equal arcs, which can limit the rotation trajectory of the rotating frame 31, so that the circular groove 41 on the raw material tank 4 containing the polylactic acid particles is located above the funnel 94, and the electric push rod 5 is started to control the fan plate 6 to expand so that it passes through the funnel 94 into the mixing tank 11;

[0068] When it is necessary to mix the raw materials in the mixing tank 11, the staff starts the mixing motor 8 through the control panel 95 to drive the mixing frame 81 to rotate, driving the mixing plate 9 rotatably connected to the mixing frame 81 to revolve, and the cylindrical pins on the rotating plate 91 fixedly installed on the mixing plate 9 are meshed with the cylindrical pins of the circular plate 82 rotatably connected to the mixing frame 81, so that the mixing plate 9 rotates while revolving, and the outer surfaces of the upper and lower mixing plates 9 are connected by synchronous belts 92 that are rotatably connected by synchronous wheels, so that they rotate synchronously. After the mixing is completed, the above steps are repeated to add natural gravel and polystyrene particles in turn for mixing;

[0069] After the crushed aggregate is mixed, the staff will add the proportioned inorganic gel, superplasticizer, titanium dioxide and water into the raw material tank 4 in sequence. The raw material tank 4 containing the inorganic gel is located above the funnel 94. The above steps are repeated and mixed in sequence. After all the raw materials are mixed, they can be allowed to enter the storage frame through the discharge pipe 93 on the mixing tank 11. The valve can regulate the flow of the mixed raw materials.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
