Description

Technical Field

[0001] This application relates to the technical field of bulk cement carriers, and particularly to a bulk cement ship tank fluidization device. Background Art

[0002] A bulk cement carrier is a specialized bulk cargo ship for transporting cement. It is a specialized bulk cargo ship. Since the bulk cement carrier transports bulk cement, to prevent cement caking and scattering, the hatch cover should be watertight. Specialized cement conveying equipment is installed on the cement carrier, and a dust collection chamber or an air filter is installed on the hatch cover. When unloading (conveying) cement from the tank of a bulk cement carrier, fluidized conveying is adopted. Air is filled into the tank from the sealed bottom (usually in several ways), and the cement powder is fluidized under the agitation of the air flow; after the pressure in the tank reaches a certain level, the discharge valve (usually in several ways) is opened, and the material is suspended in the air and "blown" out (conveyed); as the material decreases and the pressure in the tank decreases, at this time, the flow area of the discharge port is reduced (closing a certain discharge path) to maintain the pressure in the tank until the unloading is completed.

[0003] However, when the bulk cement ship tank is in use, bulk cement is stored inside the tank. When the cement is fluidized and conveyed from the bulk cement ship tank, the bulk cement stacked at the bottom of the bulk cement ship tank is not easily conveyed out, and the cement is prone to caking after being stored in the bulk cement ship tank for a long time, resulting in inconvenient fluidization of the cement and affecting the conveying of the cement.

[0004] Therefore, there is an urgent need for a bulk cement ship tank fluidization device to solve the problem that the cement stacked plate body is not easily fluidized and conveyed. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, this application provides a bulk cement ship tank fluidization device, which has the advantage of facilitating the conveying of cement and solves the problem that the cement stacked plate body is not easily fluidized and conveyed.

[0006] To achieve the above object, this application provides the following technical solution: A bulk cement ship tank fluidization device includes a bulk cement ship body, a storage tank, an air booster pump, a connecting pipe, a connection port, and an air outlet pipe. The storage tank is welded to the middle position at the top of the bulk cement ship body. The air booster pump is installed on the top of the bulk cement ship body. The connection port is arranged at the top of the storage tank. The air booster pump is communicated with a group of connection ports installed at the top of the storage tank through the connecting pipe. Sealing covers are installed on the top of the two groups of connection ports. One end of the air outlet pipe is communicated with the top of the connection port. A stirring mechanism is arranged inside the storage tank, and a communicating mechanism is arranged inside the air outlet pipe;

[0007] The stirring mechanism includes a driving motor, a support rod, a connecting sleeve, a first connecting rod, a pushing plate, a support frame and a filter screen. The driving motor is installed on the side of the storage tank away from the air booster pump. One end of the support rod is fixedly connected to the output end of the driving motor, and the other end of the support rod is rotatably connected to the inner side of the storage tank. Five groups of the connecting sleeves are fixedly connected to the outer surface of the support rod by screws. One end of the first connecting rod is welded to the outer surface of the connecting sleeve, and the other end of the first connecting rod is welded to the inner side of the pushing plate. The outer surface of the pushing plate is slidably connected to the inner surface of the storage tank. Several groups of the support frames are welded to the symmetric positions on the outer surface of the first connecting rod, and the filter screen is arranged in the slot inside the support frame.

[0008] When the cement is fluidized and output inside the storage tank, the first connecting rod stirs the cement when rotating, and the pushing plate pushes the cement stacked at the bottom of the storage tank upward. At the same time, when the support frame drives the filter screen to rotate, the filter screen crushes and filters the cement on the plate body, so that the agglomerated cement is turned into powder again, which is convenient for the fluidized transportation of the cement.

[0009] Preferably, the outer side of the pushing plate is an arc surface.

[0010] When the pushing plate rotates, it pushes the cement stacked at the bottom of the storage tank upward, which is convenient for the fluidized output of the cement.

[0011] Preferably, several groups of the support frames and the filter screen are evenly distributed inside the storage tank.

[0012] Preferably, the connecting mechanism includes a spherical cylinder, a connecting ball, a second connecting rod and a pushing disc. The spherical cylinder is welded to the plate body outside the air outlet pipe. The outer surface of the connecting ball is rotatably connected to the inner surface of the spherical cylinder. One end of the second connecting rod is welded to the outer surface of the connecting ball, and the other end of the second connecting rod is fixedly connected to the inner side of the pushing disc by screws. The outer surface of the second connecting rod is rotatably connected to the plate body outside the spherical cylinder, and a communicating hole is opened in the inner side of the pushing disc.

[0013] Preferably, a gasket is bonded to the other end of the air outlet pipe, and a bolt is threadedly connected to the plate body outside the other end of the air outlet pipe, and the bolt penetrates through the gasket.

[0014] Preferably, a slot adapted to the gasket is opened in the plate body outside the other end of the air outlet pipe.

[0015] In summary, the present application includes at least one of the following beneficial effects:

[0016] 1. For this bulk cement ship tank fluidization device, when the cement is fluidized and output inside the storage tank, as the support rod rotates, it drives the first connecting rod to rotate through the connecting sleeve. When the first connecting rod rotates, it stirs the cement. The push plate pushes the cement stacked at the bottom of the storage tank upward. At the same time, when the support frame drives the filter screen to rotate, the filter screen crushes and filters the cement on the plate body, making the caked cement turn back into powder, facilitating the fluidization and output of the cement, and enabling the better use of the bulk cement ship tank fluidization device.

[0017] 2. For this bulk cement ship tank fluidization device, when the fluidized cement is transported through the air outlet pipe, the angle of the connecting ball can be adjusted. When the connecting ball drives the communication hole to rotate to the vertical direction, the fluidized cement can be conveniently output from the air outlet pipe. When the connecting ball drives the communication hole to rotate to the horizontal direction, the connecting ball can conveniently seal the air outlet pipe, so that the fluidized cement can be hermetically stored inside the storage tank, allowing the cement to be continuously pressurized and fluidized inside the storage tank, improving the conveying efficiency of the cement.

[0024] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0025] Please refer to Figures 1-5 , a fluidization device for a bulk cement ship tank, comprising a bulk cement ship body 1, a storage tank 2, an air booster pump 3, a connecting pipe 4, a connecting port 5 and an air outlet pipe 7. The storage tank 2 is welded to the middle position at the top of the bulk cement ship body 1, and cement is stored in the storage tank 2. The air booster pump 3 is installed at the top of the bulk cement ship body 1, the connecting port 5 is arranged at the top of the storage tank 2, and the air booster pump 3 is communicated with a group of connecting ports 5 installed at the top of the storage tank 2 through the connecting pipe 4. The air booster pump 3 passes gas into the interior of the storage tank 2 through the connecting pipe 4 and the connecting port 5, thereby increasing the air pressure inside the storage tank 2, so that the cement inside the storage tank 2 can be fluidized and transported when discharged. Sealing covers 6 are installed on the tops of the two groups of connecting ports 5, and the sealing covers 6 seal the two groups of connecting ports 5. When the sealing covers 6 are opened, pipelines for increasing the fluidization output of cement or boosting equipment can be added to improve the working efficiency of the fluidization device. One end of the air outlet pipe 7 is communicated with the top of the connecting port 5, and the fluidized cement is transported through the air outlet pipe 7. A stirring mechanism is arranged inside the storage tank 2, and a communicating mechanism is arranged inside the air outlet pipe 7.

[0026] Specifically, the stirring mechanism includes a driving motor 111, a support rod 112, a connecting sleeve 113, a first connecting rod 114, a push plate 115, a support frame 116 and a filter screen 117. The driving motor 111 is installed on the side of the storage tank 2 away from the air booster pump 3. One end of the support rod 112 is fixedly connected to the output end of the driving motor 111, and the other end of the support rod 112 is rotatably connected to the inside of the storage tank 2. Five groups of connecting sleeves 113 are fixedly connected to the outer surface of the support rod 112 by screws. One end of the first connecting rod 114 is welded to the outer surface of the connecting sleeve 113, and the other end of the first connecting rod 114 is welded to the inside of the push plate 115. The outer surface of the push plate 115 is slidably connected to the inner surface of the storage tank 2. The outer surface of the push plate 115 is an arc surface. A number of support frames 116 are welded to the symmetric positions on the outer surface of the first connecting rod 114. The filter screen 117 is arranged in the slots inside the support frames 116. A number of support frames 116 and the filter screen 117 are evenly distributed inside the storage tank 2.

[0027] Through the above technical solution, when cement is stored inside the storage tank 2, the driving motor 111 is started. The driving motor 111 drives the support rod 112 to rotate. When the support rod 112 rotates, it drives the first connecting rod 114 to rotate through the connecting sleeve 113. When the first connecting rod 114 rotates, it stirs the cement. The first connecting rod 114 drives the push plate 115 and the support frame 116 to rotate. When the push plate 115 rotates, it pushes the cement stacked at the bottom of the storage tank 2 upward. At the same time, when the support frame 116 drives the filter screen 117 to rotate, the filter screen 117 crushes and filters the cement in the form of plates, so that the caked cement is turned into powder again, facilitating the fluidization output of cement and enabling the fluidization device of the bulk cement ship tank to be used better.

[0028] Specifically, the connecting mechanism includes a spherical cylinder 211, a connecting ball 212, a second connecting rod 213 and a push plate 214. The spherical cylinder 211 is welded to the plate body outside the air outlet pipe 7. The outer surface of the connecting ball 212 is rotatably connected to the inner surface of the spherical cylinder 211. One end of the second connecting rod 213 is welded to the outer surface of the connecting ball 212, and the other end of the second connecting rod 213 is fixedly connected to the inner side of the push plate 214 by screws. The outer surface of the second connecting rod 213 is rotatably connected to the plate body outside the spherical cylinder 211. A communicating hole 215 is formed in the inner side of the push plate 214. A gasket 216 is bonded to the other end of the air outlet pipe 7. A bolt 217 is threadedly connected to the plate body outside the other end of the air outlet pipe 7. The bolt 217 penetrates through the gasket 216, and a notch adapted to the gasket 216 is formed in the plate body outside the other end of the air outlet pipe 7.

[0029] Through the above technical solution, when the cement stored inside the air booster pump 3 is fluidized and conveyed through the air outlet pipe 7, the staff member pushes the push plate 214. The push plate 214 drives the connecting ball 212 to rotate through the second connecting rod 213, thereby changing the angle of the connecting ball 212. When the connecting ball 212 drives the communicating hole 215 to rotate to the vertical direction, the fluidized cement can be conveniently output from the air outlet pipe 7. When the connecting ball 212 drives the communicating hole 215 to rotate to the horizontal direction, the connecting ball 212 can conveniently seal the air outlet pipe 7, so that the fluidized cement can be hermetically stored inside the storage tank 2, enabling the cement to be continuously pressurized and fluidized inside the storage tank 2, and improving the conveying efficiency of the cement; the bolt 217 fixes the pipe connecting the air outlet pipe 7. The gasket 216 is located between the pipe connecting the air outlet pipe 7 and the air outlet pipe 7, improving the sealing performance of the air outlet pipe 7 and preventing cement leakage.

[0030] During use, when the cement is fluidized and output inside the storage tank 2, the first connecting rod 114 rotates to stir the cement, and the push plate 115 pushes the cement stacked at the bottom of the storage tank 2 upward. At the same time, when the support frame 116 drives the filter net 117 to rotate, the filter net 117 crushes and filters the cement on the plate body, so that the agglomerated cement is turned into powder again, facilitating the fluidized conveying of the cement.

[0031] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
