Description

Technical Field

[0001] This invention relates to the field of building material storage equipment technology, and in particular to a moisture-proof silo for dry-mixed mortar. Background Technology

[0002] As a premixed dry powder material, the storage quality of dry-mixed mortar directly affects its workability and final strength. After preparation, dry-mixed mortar is usually stored in mobile silos and transported to the construction site for use in conjunction with construction machinery such as continuous mixing machines.

[0003] Chinese utility model patent CN220744131U discloses a moisture-proof storage tank for dry-mixed mortar. The tank includes a storage tank with an inner tank in the middle. A support frame is provided on the outer surface of the bottom of the storage tank. An electric heating tube is installed between the inner tank and the storage tank. A controller is located on one side of the storage tank, and a water absorption box is located on the top of the storage tank. A pull-out drawer is inserted into one side of the water absorption box. First, the electric heating tube heats the material inside the inner tank. Then, a motor is started to control the stirring tube frame to stir the material, improving the uniformity of heating. A hot air box is then started to inject hot air into the fixed tube and the stirring tube frame, allowing the hot air to enter the inner tank through small holes on the surface of the fixed tube and the stirring tube frame, uniformly heating the material.

[0004] Regarding the aforementioned technologies, when the fixed pipe and mixing pipe frame are in dry mortar, and no hot air is being transported within them, fine particles in the dry mortar can easily accumulate in the small holes of the fixed pipe and mixing pipe frame. When the humidity inside the moisture-proof silo is high, the dry mortar can easily solidify in the small holes of the fixed pipe and mixing pipe frame, potentially causing blockage of these small holes. Summary of the Invention

[0005] To address the problem that dry-mixed mortar can easily solidify in the small holes of the fixed pipe and mixing pipe frame when the humidity inside the moisture-proof silo is high, thus causing blockage of the small holes, this application provides a moisture-proof silo for dry-mixed mortar.

[0006] The present application provides a moisture-proof silo for dry-mixed mortar, which adopts the following technical solution: A moisture-proof silo for dry-mixed mortar includes a moisture-proof silo, a support frame fixed to the bottom end of the moisture-proof silo, an inlet / outlet pipe provided at the bottom end of the moisture-proof silo, a valve provided on the inlet / outlet pipe, an air guide pipe fixed to the inner circumferential surface of the moisture-proof silo, an air inlet pipe fixed to the outer circumferential surface of the moisture-proof silo, the air inlet pipe being connected to the air guide pipe, multiple sealing pipes fixed to the top surface of the air guide pipe, multiple openings on the outer circumferential surface of the sealing pipes, a downward-opening exhaust pipe rotatably installed inside the sealing pipes, the exhaust pipe being connected to the air guide pipe, multiple rows of air outlets on the outer circumferential surface of the exhaust pipe, and a drive mechanism provided on the moisture-proof silo for driving the exhaust pipe to rotate.

[0007] By adopting the above technical solution, when it is necessary to dry the dry mortar in the moisture-proof cylinder, the drive mechanism is activated, which drives multiple exhaust pipes to rotate simultaneously, moving the air outlets on the exhaust pipes to the openings on the sealing pipes. Then, hot air is delivered to the air guide pipe through the air inlet pipe, and the air guide pipe delivers the hot air to the exhaust pipe. The hot air in the exhaust pipe is blown out through the air outlets, thereby drying the dry mortar in the moisture-proof cylinder. After the dry mortar in the moisture-proof cylinder is dried, the drive mechanism is activated again to drive the exhaust pipe to rotate, causing the air outlets on the exhaust pipes to rotate to the inner wall of the sealing pipe. The inner wall of the sealing pipe seals the air outlets on the exhaust pipe, thereby reducing the possibility of the dry mortar in the moisture-proof cylinder clogging the air outlets.

[0008] Preferably, the top end of the exhaust duct passes through the top surface of the desiccant, the exhaust duct is rotatably connected to the desiccant, the driving mechanism includes a gear one disposed at the top end of the exhaust duct, a gear ring is rotatably disposed at the top end of the desiccant, the gear one meshes with the gear ring, and a driving member for driving the gear ring to rotate is disposed at the top end of the desiccant.

[0009] By adopting the above technical solution, the driving component is started, which drives the gear ring to rotate. The gear ring rotates, thereby causing the exhaust duct to rotate.

[0010] Preferably, the top of the moisture-proof cylinder is provided with a mounting bracket, and the driving component includes a motor one disposed on the top surface of the mounting bracket, and a gear two disposed on the output shaft of the motor one, the gear two meshing with the gear ring.

[0011] By adopting the above technical solution, motor one is started, and the output shaft of motor one drives gear two to rotate, thereby causing gear two to drive rack to rotate.

[0012] Preferably, the moisture-proof cylinder is provided with an inner silo, and multiple connecting blocks are fixed between the outer circumferential surface of the inner silo and the inner circumferential surface of the moisture-proof cylinder. A connecting pipe is fixed to the bottom end of the inner silo and is connected to the inlet and outlet pipes. A conveying pipe is provided through the inner top surface of the inner silo. A rotating shaft is rotatably installed on the inner top surface of the moisture-proof cylinder. The rotating shaft passes through the conveying pipe. A spiral blade is provided on the outer circumferential surface of the rotating shaft. A motor is fixed to the top of the moisture-proof cylinder, and the bottom end of the output shaft of the motor is fixedly connected to the bottom end of the rotating shaft.

[0013] By adopting the above technical solution, the second motor is started, the output shaft of the second motor drives the first rotating shaft to rotate, the first rotating shaft drives the first spiral blade to rotate, the first spiral blade rotates the dry mortar in the inner silo from the top of the first conveying pipe, and the dry mortar slides down from the top of the inner silo, which makes it easier to turn the dry mortar in the inner silo, and thus makes it easier for the air blown out of the exhaust pipe to dry the dry mortar.

[0014] Preferably, a second conveying pipe is fixedly installed through the inner bottom surface of the inner silo, a second rotating shaft is installed inside the second conveying pipe, the top end of the second rotating shaft passes through the top surface of the inner silo, the second rotating shaft is rotatably connected to the inner silo, a second helical blade is installed on the second rotating shaft, and a power component for driving the second rotating shaft to rotate is installed on the first rotating shaft.

[0015] By adopting the above technical solution, the dried dry-mixed mortar is piled on the inner bottom surface of the moisture-proof cylinder. When the rotating shaft rotates, the rotating shaft drives the power component, which in turn drives the rotating shaft to rotate. The rotating shaft drives the spiral blade to rotate, so that the spiral blade transports the dried dry-mixed mortar on the inner bottom surface of the moisture-proof cylinder to the inner silo during the rotation process.

[0016] Preferably, the power component includes a gear three disposed on the first rotating shaft, and a gear four disposed on the second rotating shaft, the gear meshing with the gear four.

[0017] By adopting the above technical solution, when the rotating shaft rotates, the rotating shaft rotates and drives the gear three to rotate, the gear three drives the gear four to rotate, thereby causing the gear four to drive the rotating shaft two to rotate.

[0018] Preferably, the top of the inner silo is conical.

[0019] By adopting the above technical solution, the top of the inner silo is set as a cone shape, which makes it easier for the rotating shaft to drive the spiral blade to rotate, so that when the spiral blade rotates out the dry mortar, the dry mortar can slide down along the top of the inner silo.

[0020] Preferably, a protective box is fixed to the inner top surface of the moisture-proof cylinder, the first rotating shaft and the second rotating shaft pass through the protective box, the first rotating shaft and the second rotating shaft are rotatably connected to the protective box respectively, and the third gear and the fourth gear are located inside the protective box.

[0021] By adopting the above technical solution, a protective box is set on the inner top surface of the moisture-proof cylinder, so that gears three and four are placed inside the protective box. The protective box protects gears three and four, thereby reducing the entry of dry-mixed mortar into the teeth of gears three and four, and thus improving the service life of gears three and four.

[0022] Preferably, a humidity sensor is installed inside the inner silo, and a controller is installed on the desiccant. The output terminal of the humidity sensor is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the control terminals of motor one and motor two, respectively.

[0023] By adopting the above technical solution, a humidity sensor is installed inside the moisture-proof cylinder to detect the humidity of the dry-mixed mortar inside the cylinder in real time and transmit the detected humidity signal to the controller. The controller compares the received humidity signal with the set humidity signal. When the humidity signal received by the controller is greater than the set humidity signal, the controller controls motor one and motor two to start. The output shaft of motor one drives gear two to rotate, gear two drives rack to rotate, rack drives gear one to rotate, gear one drives exhaust duct to rotate, and exhaust duct outlet rotates to the opening. At the same time, the output shaft of motor two drives rotating shaft one to rotate, rotating shaft one drives spiral blade one to rotate, and spiral blade one rotates the dry-mixed mortar in the inner cylinder to dry it.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to dry the dry mortar in the moisture-proof cylinder, start the drive mechanism. The drive mechanism drives multiple exhaust pipes to rotate simultaneously, so that the air outlets on the exhaust pipes move to the openings on the sealing pipes. Then, hot air is delivered to the air guide pipe through the air inlet pipe, and the air guide pipe delivers the hot air to the exhaust pipe. The hot air in the exhaust pipe is blown out through the air outlets, so that the hot air blown out of the air outlets dries the dry mortar in the moisture-proof cylinder. After the dry mortar in the moisture-proof cylinder is dried, start the drive mechanism again to drive the exhaust pipe to rotate, so that the air outlets on the exhaust pipes rotate to the inner wall of the sealing pipe, so that the inner wall of the sealing pipe seals the air outlets on the exhaust pipe, thereby reducing the possibility of the dry mortar in the moisture-proof cylinder clogging the air outlets. 2. Start motor two. The output shaft of motor two drives rotating shaft one to rotate. Rotating shaft one drives spiral blade one to rotate. Spiral blade one rotates the dry mortar in the inner silo from the top of conveying pipe one. The dry mortar slides down from the top of the inner silo, which makes it easier to turn the dry mortar in the inner silo, and thus makes it easier for the air blown out of the exhaust pipe to dry the dry mortar. 3. The dried dry mortar accumulates on the inner bottom surface of the moisture-proof cylinder. When the rotating shaft rotates, the rotating shaft drives the power component, which in turn drives the rotating shaft to rotate. The rotating shaft drives the spiral blade to rotate, thereby allowing the spiral blade to transport the dried dry mortar on the inner bottom surface of the moisture-proof cylinder to the inner silo during the rotation process.

[0034] Reference Figure 2 and Figure 4 The moisture-proof cylinder 1 contains an inner chamber 3. The outer circumference of the inner chamber 3 is spaced apart from the inner circumference of the moisture-proof cylinder 1. The top of the inner chamber 3 is conical. Multiple connecting blocks 31, each with a pointed top, are fixed between the outer circumference of the inner chamber 3 and the inner circumference of the moisture-proof cylinder 1. A connecting pipe 32 is fixed to the bottom of the inner chamber 3, and is connected to the inlet / outlet pipe 12. A conveying pipe 33 is fixedly installed through the top surface of the inner chamber 3.

Gears 3 43 and 44 are located inside the protective box 45.

[0036] Reference Figure 1 and Figure 4 A humidity sensor 5 for detecting the humidity of dry-mixed mortar is fixed inside the inner silo 3. A controller 51 is fixed on the outer circumference of the moisture-proof cylinder 1. The output end of the humidity sensor 5 is electrically connected to the input end of the controller 51. The output end of the controller 51 is electrically connected to the control ends of motor 1 28 and motor 2 36 respectively.

[0037] The implementation principle of a moisture-proof silo for dry-mixed mortar in this embodiment is as follows: A humidity sensor 5 is installed inside the inner silo 3 to monitor the humidity of the dry-mixed mortar inside the inner silo 3 in real time and transmit the detected humidity signal to the controller 51. The controller 51 compares the received humidity signal with a set humidity signal. When the humidity signal received by the controller 51 is greater than the set humidity signal, the controller 51 controls the motor 1 28 and the motor 2 36 to start. The output shaft of the motor 1 28 drives the gear 2 29 to rotate, the gear 2 29 drives the rack to rotate, the rack drives the gear 1 25 to rotate, and the gear 1 25 drives the exhaust duct 23 to rotate, so that the air outlet on the exhaust duct 23 rotates to the opening 221 on the sealing pipe 22, so that the air inlet duct 21 delivers hot air to the air guide duct 2. The air duct 2 delivers hot air to the exhaust duct 23, causing the hot air to be blown out from the air outlet 24 on the exhaust duct 23. At the same time, the output shaft of the second motor 36 drives the rotating shaft 34 to rotate, which in turn drives the spiral blade 35 to rotate. The spiral blade 35 causes the dry mortar in the inner silo 3 to be spiraled out from the top of the conveying pipe 33, allowing the dry mortar to slide down the top of the inner silo 3 and around its perimeter. This allows the hot air blown out of the exhaust duct 23 to dry the dry mortar. When the rotating shaft 34 rotates, it drives the gear 43 to rotate, which in turn drives the gear 44 to rotate. The gear 44 then drives the rotating shaft 41 to rotate, which in turn drives the spiral blade 42 to rotate. This allows the spiral blade 42 to rotate and transport the dry mortar dried at the bottom of the moisture-proof cylinder 1 into the inner silo 3. After the dry mortar in the moisture-proof silo is dried, start motor 28. The output shaft of motor 28 drives gear 29 to rotate. Gear 29 drives rack to rotate. Rack drives gear 25 to rotate. Gear 25 drives exhaust pipe 23 to rotate. This moves the air outlet 24 on exhaust pipe 23 to the inner wall of sealing pipe 22, sealing the air outlet 24 and reducing the possibility of dry mortar clogging the air outlet 24.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
