Description
Technical Field
[0001] The invention relates to the technical field of bulk cement storage and transportation, in particular to an air bag cement box. Background Art
[0002] The existing equipment for storing and transporting bulk cement cannot adapt well to the narrow space underground in mines, so bagged cement is widely used in underground construction projects, which easily causes dust pollution and occupational diseases. Manual handling of bagged cement hinders the mechanization of mining concrete technology and restricts the development of automation and intelligent technology in the storage and transportation of shotcreting and grouting materials in mines.
[0003] Existing equipment for bulk cement storage and transportation includes cement towers, cement silos, and cement tankers. Cement towers and cement silos are large in size and tonnage (30 tons to 500 tons) and are only used in fixed locations on large construction sites. They cannot be moved and are unable to meet the needs of small construction sites and small underground spaces. In addition, the cement silo has a separate conical hopper at the bottom and requires additional facilities such as a discharge valve, vibrator, and material delivery pipe to achieve cement transportation. The operation and use process is complex. Although cement tankers are easy to move, they are still large in size and tonnage (8-30 tons) and still cannot meet the transportation and use requirements of underground mine spaces. Although some companies have developed small cement tankers and put them into experimental use in mines, cement tankers are pressure vessels with high manufacturing and use costs. In addition, compressed air is required to squeeze the material when removing it, which can easily cause dust to fly. Therefore, to address the above problems, a small mobile cement storage container with an airbag cement box is proposed. The storage tonnage is 0.5-2 tons to solve the storage and transportation problems of bulk cement in underground mines and small ground construction sites. Summary of the Invention
[0004] The purpose of the present invention is to provide an airbag cement box to solve the problem of the lack of cement storage containers with low cost, reasonable size, easy mobility and simple operation in existing mines, and to solve the problem that bagged cement is easily affected by moisture and deteriorated in mines, and that manual labor pollutes the air and is prone to silicosis. The invention provides key supporting technologies for automated and intelligent delivery for the storage, preparation and transportation of mine shotcreting and grouting materials.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] An airbag cement box comprises a cement box body and a discharge port. The discharge port is provided at the bottom of a box wall on one side of the cement box body, an air nozzle mounting hole is provided on the box wall of the cement box body, an airbag fixing bracket is fixedly connected to the inner side of the box wall of the cement box body, an airbag body is fixedly connected to the inner side of the box wall of the cement box body, an air nozzle for air inlet and outlet is fixedly connected to one side of the airbag body, and a box cover is provided at the upper end of the cement box body.
[0007] Preferably, a cavity is formed inside the airbag body. The inside of the airbag body communicates with the inside of one end of the air nozzle. The outside of the air nozzle is inserted and fixed inside the air nozzle mounting hole. There are two airbag bodies, and the number of air nozzles, air nozzle mounting holes and airbag bodies is the same. One side of the airbag body is inclined at 45°. The airbag fixing bracket is fixed in the cement box body at an inclination of 45°.
[0008] Preferably, the inside of the discharge port communicates with the inside of the V-shaped groove of the airbag hopper. The lower end of the discharge port is flush with the bottom of the V-shaped groove of the airbag hopper. The discharge port is located at the lower end of the box wall of the cement box body.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] In the present invention, through the arranged airbag body, airbag fixing bracket, fixing bolt, air nozzle, discharge port and cement box body, the device has a small volume and a high utilization rate of the effectively loaded space. When taking out the cement in the cement box, the airbag body is inflated through the air delivery hose and the air needle, so that the airbag body deforms to form a V-shaped groove of the airbag hopper inside the cement box. It can not only quickly take out the cement in the cement storage tank, improve the working speed and reduce manual operation, but also disassemble and replace the airbag body. The cement box is sealed through the box cover. The present invention is a cement storage container with a brand-new concept, low cost, reasonable shape, convenient movement and simple operation, which can realize the mechanized transportation of bulk cement in the narrow space of the mine and provide a technical foundation guarantee for mechanized and automated construction of concrete and grouting underground the mine.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-5 , the present invention provides a technical solution:
[0019] An airbag cement box includes a cement box body 1 and a discharge port 2. A discharge port 2 is provided at the bottom of one side wall of the cement box body 1. An air nozzle mounting hole 3 is provided on the wall of the cement box body 1. An airbag fixing bracket 6 is fixedly connected to the inner side of the wall of the cement box body 1, and an airbag body 8 is fixedly connected to the inner side of the airbag fixing bracket 6. An air nozzle 7 for inlet and outlet of air is fixedly connected to one side of the airbag body 8. A box cover 4 is provided at the upper end of the cement box body 1.
[0020] The inner side of the airbag body 8 is provided with a cavity, and the inner side of the airbag body 8 is communicated with the inner side of one end of the air nozzle 7. The outer side of the air nozzle 7 is inserted and fixed inside the air nozzle mounting hole 3. The number of the airbag bodies 8 is two, and the numbers of the air nozzles 7, the air nozzle mounting holes 3 and the airbag bodies 8 are the same. One side of the airbag body 8 is inclined at 45°. The airbag fixing bracket 6 is fixed in the cement box body 1 at an inclination of 45°, which is convenient for inflating the inside of the airbag body 8 through the air nozzle 7. The inner side of the discharge port 2 is communicated with the V-shaped groove 5 of the airbag hopper. The inner side of the discharge port 2 is communicated with the inner side of the V-shaped groove 5 of the airbag hopper. The lower end of the discharge port 2 is flush with the bottom of the V-shaped groove 5 of the airbag hopper. The discharge port 2 is located at the lower end of the wall of the cement box body 1, which is convenient for pumping cement.
[0021] Workflow: A bulk cement tower is set up in the industrial square on the ground of the mine. The airbag cement box is filled on the ground of the mine and transported through open-top containers, flatbed trucks and monorail cranes. When filling, first remove the upper cover 4 of the cement box body 1, use a special filling cover with sealing, exhaust and dust removal functions configured by the filling equipment to seal the cement box body 1, and use a plug, end cover or connecting hose device to block the discharge port 2. Insert an air needle into the air nozzle 7 to deflate the airbag body 8, start the filling equipment, and use the compressed air continuously filled in the cement tower to transport the bulk cement into the cement box body 1 through a pipeline. The filled cement squeezes out the air in the airbag body 8 by gravity. The airbag cement box is moved to the construction site by mine transportation equipment. Open the seal of the discharge port 2, insert the auger feeder into the discharge port 2 to extract cement. When about half of the cement in the cement box body 1 is extracted, insert an air needle connected to a compressed air delivery hose into the air nozzle 7. Compressed air enters the airbag body 8 through the air nozzle 7, and the airbag body 8 expands to form an airbag hopper V-shaped groove 5 at the bottom of the cement box, squeezing the cement at the bottom of the cement box into the airbag hopper V-shaped groove 5 to facilitate the auger feeder to extract all the cement in the box. When it is necessary to maintain or replace the airbag body 8, remove all the fixing bolts. After all the fixing bolts are far away from the reserved screw holes and the internal convex screw grooves, the airbag fixing bracket 6 and the airbag body 8 can be disassembled. The flexible air nozzle 7 and the air nozzle mounting hole 3 are connected by buckling, which is convenient for quick installation and disassembly, and then the airbag body 8 and the airbag fixing bracket 6 can be taken out.
[0022] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
