Description

Technical field:

[0001] The invention relates to the technical field of emulsion explosive manufacturing equipment, and more specifically to a double-cooling conveying system for a latex matrix. Background technology:

[0002] Existing emulsion explosives are a kind of water phase and oil phase that have been heated. Under the action of high-speed operation and strong shear force, with the help of emulsifiers, the droplets of oxidant salt aqueous solution are evenly dispersed in the oil phase continuous medium containing porous substances such as dispersed bubbles or hollow glass microspheres, and then sensitized to form a water-in-oil emulsion explosive;

[0003] During the manufacturing process, the water phase and the oil phase need to be emulsified and stirred to form a latex matrix, which needs to be transported to subsequent equipment through a conveyor belt. Since the temperature of the latex matrix is ​​high after it is made, it needs to be sensitized subsequently. Sensitization requires that the emulsified matrix be kept below 65°C. The existing conveyor rack generally has multiple cooling fans fixed on the upper part for blowing and heat dissipation, and the cooling effect is limited, so that the temperature of the latex matrix is ​​limited during the transportation process, affecting the subsequent sensitization effect. Summary of the invention:

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a double-cooling conveying system for a latex matrix, which can cool the latex matrix by double cooling of air cooling and water cooling when it is conveyed by a conveyor steel belt, so that its temperature is greatly reduced and the temperature control effect is good.

[0049] By driving the reduction motor to operate, the conveying steel belt 12 is rotated and conveyed.

[0050] Furthermore, an adjustment support frame 50 is fixed to the top surface of the right part of the front and rear transverse beams on the upper part of the conveying frame 10, and two vertical adjustment slots are provided on the adjustment support frame 50. The adjustment block 51 is inserted into the corresponding vertical adjustment slots. The front and rear parts of the left and right sides of the adjustment block 51 are formed with extension parts. The adjustment support frame 50 on the left and right sides of the vertical adjustment slot is located between the corresponding two extension parts.

[0051] A vertical adjustment screw connection hole is formed on the top plate of the adjustment support frame 50 just above the vertical adjustment slot, and the adjustment screw 52 is screwed into the vertical adjustment screw connection hole. The bottom end of the adjustment screw 52 extends into the corresponding vertical adjustment slot and is movably connected to the top surface of the adjustment block 51. The top end of the adjustment screw 52 extends out of the top surface of the top plate of the adjustment support frame 50 and is fixed with a rotating wheel 53 and a locking nut 54 screwed thereon. The bottom surface of the locking nut 54 is pressed against the top surface of the top plate of the adjustment support frame 50. By loosening the locking nut 54 and rotating the adjustment screw 52, ​​the height position of the adjustment block 51 can be changed, and the height position adjustment of the corresponding upper transmission roller 55 can be achieved. After the adjustment is completed, the locking nut 54 can be tightened, which is very convenient.

[0052] The front and rear ends of the upper transmission roller 55 are movably connected to the two corresponding adjustment blocks 51 at the front and rear through bearings.

[0053] The upper transmission roller 55 is located above and close to the top surface of the upper belt body of the corresponding conveyor steel belt 12.

[0054] The upper transmission roller 55 is a cylindrical roller body, which plays the role of evenly spreading the latex matrix on the top surface of the upper belt body of the steel belt conveyor 12 for cooling and reducing the temperature.

By rotating the push rod of the electric push rod 22, the push rod is retracted, so that the cooling fan 21 is tilted, thereby changing the amount of air blown to the top surface of the upper belt body of the conveyor steel belt 12, thereby changing the cooling efficiency and cooling effect of the latex matrix transported by the upper belt body as needed. For example, when it is necessary to improve the cooling effect, the air outlet of the cooling fan 21 is located directly above the conveyed latex matrix to achieve comprehensive blowing. When it is necessary to reduce the cooling effect, the push rod of the electric push rod 22 is retracted to flip the cooling fan 21, reduce the amount of air blown to the latex matrix, and temporarily delay the cooling effect.

For example, when the temperature of the latex matrix is ​​high, a larger water spray volume is required, and when the temperature of the latex matrix is ​​low, a smaller water spray volume is required; and the water after the heat exchange is blocked by the transparent plastic flexible baffles 1 on both sides, enters the water receiving basin body 30, and then enters the return pipe 5 from the drainage head 2 (the water receiving basin body 30 of this embodiment is an integral one, and the cooling water spray pipe grid 40 is also a separate one , it can also be a water receiving basin body 30 formed by a plurality of branch water receiving basin bodies close to each other to form an integral whole, a branch cooling water spraying pipe grid is provided directly above each branch water receiving basin body, the water inlet pipes of all branch cooling water spraying pipe grids can be connected to the corresponding control valves, the water inlets of all control valves are connected to the branch joints of the multi-way joint through connecting pipes, the main joint of the multi-way joint can be connected to the water main 100, which can close some control valves according to cooling needs, and can achieve partial cooling without opening all of them), and then enter the return main pipe 6, and then enter the transition water storage tank 80, and then flow out from the side through hole 82 of the vertical water spraying pipe 81;

[0075] The top surface corresponding to the side through hole 82 is formed with an extension piece 83 extending obliquely outward. The side through hole 82 and the extension piece 83 allow the water flowing out of the vertical water spray pipe 81 to be dispersed. At the same time, the extension piece 83 increases the contact area, and the lower cooling fan 8 blows air to it, thereby increasing the heat exchange effect, so that the refluxed water is quickly cooled down. The cooled water enters the middle filter chamber 73 from the lower flow through hole 711. The particulate matter in the water can be in the lower part of the middle filter chamber 73, and the floating matter is filtered through the filter screen plate 79. Finally, the filtered water enters the water absorption chamber 72 through the upper flow through groove 712, and can be recycled. It can cool down the circulating water temperature and filter it, and the use effect is good.

[0076] After a certain period of use, the solid matter at the bottom of the middle filter cavity 73 can be salvaged to prevent the lower flow through hole 711 from being blocked.

[0077] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
