Description

Technical Field

[0002] Cementitious sand and gravel concrete is a new type of building material formed by mixing cement, sand, gravel and a coagulant. Its main characteristics are adding a cementitious material to the concrete, making it have better strength and seismic resistance, and at the same time improving the durability, waterproofness and durability of the concrete, with the characteristics of high strength, good durability, strong seismic performance, good heat preservation performance and easy operation.

[0003] Traditional devices for preparing cementitious sand and gravel usually consist of a concrete mixer, a feeding system, a batching system, a control system, a storage and conveying device. The overall structure is complex and requires interval setting, resulting in the inability to prepare cementitious sand and gravel on the construction site. It is necessary to use a mixing truck to transport back and forth between the construction site and the preparation plant, increasing the transportation and use costs. Moreover, when mixing cementitious sand and gravel, it is usually stirred in one direction by a mixing tank, and the stirring effect is poor, and phenomena such as "undercooked materials" and "powder packets" are likely to occur, affecting the quality of cementitious sand and gravel.

[0080] The pressure data between the pressing block 94 and the spring 96 is detected by the pressure sensor 503, the data of the pressure sensor 503 and the touch screen 92 is received by the PLC controller 97, and the opening and closing of the solenoid valve 501 and the second motor 302 are controlled by the PLC controller 97 by using the relay 98.

[0081] In one embodiment, when the total amount of cemented gravel is greater than the capacity of the batching cylinder 301, the total amount of cemented gravel can be split and calculated according to the capacity of the batching cylinder 301, so as to convey the cemented gravel raw materials to the mixing tank 104 and the inner mixing tank 704 in batches by using the method of multiple conveyances.

[0082] When the present invention is in operation: The silo skid 101 and the mixing skid 102 are respectively transported and fixed at the construction site, and then the movable conveying pipe 401 is connected to one side of the tank cover 601 by means of the connecting piece 403 to complete the assembly between the silo skid 101 and the mixing skid 102, so as to complete the preparation work of cemented gravel at the construction site.

[0083] After the skid-mounted cemented gravel preparation device is assembled, the movable material guiding pipe 201 drives the connecting head 202 to insert into the cemented gravel raw material, and then the output shaft of the first motor 203 drives the first flexible auger 204 to rotate. The rotating first flexible auger 204 uses the connecting head 202 and the material guiding pipe 201 to push the cemented gravel raw material into the interior of the raw material bin 103 for storage, so as to store different cemented gravel raw materials in multiple raw material bins 103 respectively.

[0084] When it is necessary to prepare cemented gravel, the amount of cemented gravel to be prepared each time is input into the PLC controller 97 according to the actual needs by using the touch screen 92, and then the PLC controller 97 calculates the amount of each raw material according to the total amount of cemented gravel. Among them, cement accounts for 10-15% of the total amount of cemented gravel, sand accounts for 25-40% of the total amount of cemented gravel, gravel accounts for 30-50% of the total amount of cemented gravel, and water accounts for 10-15% of the total amount of cemented gravel; then the PLC controller 97 uses the relay 98 to start the solenoid valve 501 to work in sequence according to the calculation result. The working solenoid valve 501 opens the bottom of the raw material bin 103, so as to inject the cemented gravel raw material stored in the raw material bin 103 into the interior of the batching cylinder 301 by means of the corrugated pipe 502. Then, under the action of pressure, the batching cylinder 301 drives the pressing block 94 to move by means of the pipe sleeve 93. The moving pressing block 94 drives the pressure sensor 503 to squeeze the spring 96, and then the pressure sensor 503 detects the pressure data between the pressing block 94 and the spring 96 and feeds back the detection result to the PLC controller 97. Then the PLC controller 97 calculates the amount of raw material entering the batching cylinder 301 according to the initial detection result and the feedback detection result of the pressure sensor 503. When the data detected by the pressure sensor 503 reaches the usage standard of the cemented gravel raw material, the PLC controller 97 uses the relay 98 to start a solenoid valve 501 to close the bottom of one raw material bin 103 and start another solenoid valve 501 to open the bottom of another raw material bin 103, so as to sequentially add cement, sand, gravel and water into the batching cylinder 301 in a quantitative manner to complete the raw material proportioning operation.

[0085] After the raw material ratio is completed, the PLC controller 97 uses the relay 98 to start the second motor 302 to work. The working second motor 302 drives the auger column 303 to rotate. The rotating auger column 303 pushes the raw materials in the batching cylinder 301 into the conveying pipe 401. Then, the auger column 303 drives the second flexible auger 402 to rotate. The rotating second flexible auger 402 pushes the raw materials in the conveying pipe 401 into the inside of the mixing tank 104 and the inner mixing tank 704.

[0086] After the raw material transportation is completed, the conveying pipe 401 is removed from the tank cover 601 by using the connecting piece 403. Then, the third motor 701 is started to drive the central shaft 702 and the first bevel gear 762 to rotate. The rotating first bevel gear 762 drives the third bevel gear 764 to rotate by using the second bevel gear 763. The rotating third bevel gear 764 drives the inner mixing tank 704 to rotate in the mixing tank 104. The rotating inner mixing tank 704 drives the mixing blades 705 to reversely stir the cemented gravel. At the same time, the rotating central shaft 702 drives the mixing frame 703 to rotate forward in the inner mixing tank 704, so as to use the moving mixing frame 703 to forwardly stir the cemented gravel raw materials. Thus, the mixing operation of the cemented gravel raw materials can be quickly completed by means of two-way stirring, the stirring effect and efficiency are improved, and the appearance of the phenomena of "undercooked materials" and "powder packets" is reduced.

[0087] When the cemented gravel raw materials are mixed in the inner mixing tank 704, the limit on the tank cover 601 is released by rotating the locking member 602, so as to move the tank cover 601 to open one end of the mixing tank 104. Then, the piston rod of the hydraulic cylinder 801 is pushed to drive the connecting pipe 802 to move. The moving connecting pipe 802 provides a thrust for the bottom side of the mixing tank 104. Then, in cooperation with the central collar 803, the mixing tank 104 is integrally tilted towards the direction of the tank cover 601, so as to pour out the mixed cemented gravel from the inner mixing tank 704 and complete the discharging operation.

[0088] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
