Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive production equipment, specifically to an online drying device for emulsion explosive rolls. Background Technology

[0002] In the production process of emulsion explosives, the emulsion explosives are cooled in a water bath after being filled, and then dried before being transported to the packaging process. In the existing technology, because some water is carried on the conveyor line when it is sent from the water bath, a long conveyor line is usually set up and multiple fans are fixed above the conveyor line. Even so, the drying effect is not very good and the whole drying process is slow. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an online drying device for emulsion explosive rolls with reasonable structural design and good drying effect.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An online drying device for emulsion explosive rolls includes a dewatering conveyor line and an air-drying conveyor line. The air-drying conveyor line comprises an inclined chute and a horizontal conveyor. The discharge end of the dewatering conveyor line is connected to the high end of the inclined chute, and the low end of the inclined chute is connected to the feed end of the horizontal conveyor. A first blower mechanism is fixedly connected above the inclined chute, and a second blower mechanism is fixedly connected above the horizontal conveyor. The emulsion explosive rolls, cooled in a water bath, are dewatered via the dewatering conveyor line, then rolled and absorbed water via the inclined chute, and finally air-dried by the horizontal conveyor.

[0006] Furthermore, the drain conveyor line includes a frame, a mesh conveyor belt, and a downward blower mechanism. The mesh conveyor belt is inclined upward from the feed end to the discharge end. Multiple baffles are fixedly connected at equal intervals on the outer surface of the mesh conveyor belt, and the baffles extend along the width direction of the mesh conveyor belt. A downward blower mechanism is fixedly connected on the frame and above the mesh conveyor belt.

[0007] Furthermore, the downward blowing mechanism includes multiple air supply pipes, a distribution pipe, a blower, and a mounting bracket. The mounting bracket is fixedly connected to the frame, and the air supply pipes and distribution pipes are fixedly connected to the mounting bracket. All air supply pipes are closed at one end and fixedly connected to the same distribution pipe at the other end. The distribution pipe is closed at both ends and connected to all air supply pipes. Multiple air outlets are fixedly connected to the bottom of each air supply pipe. The distribution pipe is finally connected to and communicates with the air outlet of the blower.

[0008] Furthermore, the inclined slide includes a stainless steel mesh slide, baffles on both sides of the width direction of the mesh slide, and an absorbent pad laid on the inner surface of the mesh slide.

[0009] Furthermore, both ends of the absorbent pad are pressed against the inner surface of the mesh slide with fixing clips. Correspondingly, grooves for accommodating the fixing clips are formed on the mesh slide so that the upper surface of the fixing clips does not protrude above the top of the grooves, thus avoiding affecting the downward movement of the emulsion explosive roll. One end of each fixing clip is rotatably connected to the baffle or the mesh slide.

[0010] Furthermore, the first blower mechanism includes an inverted U-shaped hood and an air inlet pipe, wherein the air inlet pipe is connected to the top of the inverted U-shaped hood, and an air curtain machine or a windproof rubber curtain is fixedly connected to the inner top of the two open sides of the inverted U-shaped hood.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a desiccant conveyor line before air drying. The downward blowing mechanism of the desiccant conveyor line, in conjunction with the mesh conveyor belt, facilitates the removal of moisture from the emulsion explosive roll, saving time for subsequent air drying. The inclined slide, in conjunction with the first blowing mechanism, allows the emulsion explosive roll to roll down the inclined slide while the absorbent pad absorbs moisture from its surface. The airflow further dries the surface of the explosive roll, while simultaneously drying the absorbent pad. Finally, the second blowing mechanism on the horizontal conveyor effectively ensures the drying effect of the explosive roll. Compared to existing technologies, this invention significantly shortens the conveyor line length and drying time. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings. Any parts not detailed below are based on existing technology in the field.

[0022] like Figure 1-7 As shown, the present invention provides an online drying device for emulsion explosive rolls, comprising a dewatering conveyor line and an air-drying conveyor line.

[0023] The drain conveyor line includes a frame 1, a perforated conveyor belt 2, and a downward blowing mechanism 3. The perforated conveyor belt 2 is inclined upwards from the feed end to the discharge end. Vertically arranged baffles are fixedly connected to both sides of the frame 1 along the width direction of the perforated conveyor belt 2. Similar to existing technology, the perforated conveyor belt 2 forms a ring conveyor belt after passing around the active roller and the passive roller rotatably connected to the frame 1. The active roller is coaxially connected to the output shaft of the servo motor. Multiple baffle strips 4 are fixedly connected at equal intervals on the outer surface of the mesh conveyor belt 2. The baffle strips 4 extend along the width direction of the mesh conveyor belt 2. As needed, each baffle strip 4 can be provided with a drainage hole that penetrates its bottom upper and lower sides (the inclination direction of the drainage hole is parallel to the inclination direction of the mesh conveyor belt 2). A return water tank with the same inclination can be fixedly connected on the frame and below the mesh conveyor belt 2. The water drained from the mesh conveyor belt 2 falls into the return water tank and then flows into the water bath. The lower end of the mesh conveyor belt 2 and the lower end of the return water tank are both located in the water bath. A downward blower mechanism 3 is fixedly connected on the frame 1 and above the mesh conveyor belt 2. The downward blowing mechanism 3 includes multiple air supply pipes 3.1, a distribution pipe 3.2, a blower 3.3, and a mounting frame 3.4. The mounting frame 3.4 consists of a mounting plate and four rectangularly distributed support legs. The bottom of the four support legs is fixedly connected to the frame 1, and the mounting plate is fixed to the top of the four support legs. The mounting plate is also inclined parallel to the mesh conveyor belt 2. The multiple air supply pipes 3.1 and one distribution pipe 3.2 are fixedly connected to the bottom of the mounting plate. All the air supply pipes 3.1 are evenly and side by side along the width of the mesh conveyor belt 2. The air supply pipes 3.1 are inclined longitudinally. The lower end of the air supply pipe is closed, and the upper end is fixedly connected to the same horizontally arranged distribution pipe 3.2. Multiple vertically extending air outlets 3.11 are fixedly connected to the bottom of each air supply pipe 3.1. The two ends of the distribution pipe 3.2 are closed and connected to all the air supply pipes 3.1. The distribution pipe 3.2 is threadedly connected to the air outlet of the blower through a corrugated pipe. A blower supplies ambient temperature air to multiple air supply pipes 3.1, thereby promoting the drainage of water carried by the explosive rolls downwards. Depending on actual needs, the downward blowing mechanism 3 can be installed only on a section of the mesh conveyor belt 2 near the discharge end; if conditions permit, it can of course be installed on multiple sections of the mesh conveyor belt 2.

[0024] The air-drying conveyor line includes an inclined slide 5 and a horizontal conveyor 6. The discharge end of the mesh conveyor belt 2 of the dewatering conveyor line is connected to the high end of the inclined slide 5, and the low end of the inclined slide 5 is connected to the feed end of the horizontal conveyor 6. The horizontal conveyor 6 is a conventional belt conveyor.

[0025] The inclined slide 5 includes a stainless steel mesh slide 5.1 (with several water passage holes), baffles 5.2 on both sides of the width of the mesh slide 5.1 (both the high and low ends of the mesh slide extend beyond the baffles 5.2), and an absorbent pad 5.3 laid on the inner surface of the mesh slide. The mesh slide 5.1 is supported on the ground by multiple support columns. The inner surface of the mesh slide 5.1 is smooth. On the high and low sides of the inner surface of the mesh slide 5.1, there are downwardly recessed grooves for accommodating the fixing clips 5.4. The depth of the grooves is such that the upper surface of the fixing clip does not exceed the top of the groove, so as not to affect the downward movement of the emulsion explosive roll. The two fixing clips 5.4 are rotatably connected to the high and low ends of one of the baffles 5.2 in the conventional direction. Each fixing clip 5.4 is a conventional spring clip structure, except that the clip used to clamp the absorbent pad is a thin sheet structure. The two fixing clips are used to clamp the two ends of the absorbent pad 5.3. This structure facilitates the replacement of the absorbent pad. The absorbent pad uses a standard absorbent material.

[0026] A first blower mechanism 7 is fixedly connected above the inclined slide 5. The first blower mechanism 7 includes an inverted U-shaped hood 7.1 and an air inlet pipe 7.2. The bottom ends of the inverted U-shaped hood 7.1 can be directly fixedly connected to the top of the baffle plates on both sides of the inclined slide 5, or can be directly supported on the ground by an independent support frame (but the bottom ends of the hood 7.1 must be in contact with the top of the baffle plates on both sides). An air curtain machine 7.3 is fixedly connected to the inner top of the high-end side and the inner top of the low-end side of the inverted U-shaped hood 7.1, and the air outlet of the air curtain machine is vertically downward (a windproof plastic curtain can also be hung in a conventional manner, but a very small gap must be ensured between the bottom of the windproof plastic curtain and the upper surface of the water-absorbing pad on the inclined slide). An air inlet pipe 7.2 is fixedly connected to the center of the top of the inverted U-shaped hood 7.1. The air inlet pipe 7.2 passes through the inner and outer sides of the top of the inverted U-shaped hood, and the other end of the air inlet pipe 7.2 is connected to a pipe, blower or other conventional pressurized air source in a conventional manner.

[0027] A second blower mechanism 8 is fixedly connected above the horizontal conveyor 6. The second blower mechanism 8 is a blower commonly used in the prior art for drying emulsion explosives, including a gantry frame and multiple blowers fixed at the bottom of the gantry frame.

[0028] During use, after the emulsified explosive has cooled in the water bath, it is conveyed obliquely upward by the draining conveyor line. The water it carries is drained downward through the mesh of the mesh conveyor belt. With the assistance of the downward blower mechanism, the water is further separated from the explosive roll. The explosive roll discharged from the discharge end of the draining conveyor line falls onto the inclined slide 5. As the emulsified explosive roll roll rolls downward, the water on its surface is absorbed by the water-absorbing pad. With the help of the first blower mechanism, the emulsified explosive roll roll is dried while the water-absorbing pad is dried. Finally, the emulsified explosive roll roll falls onto the conveyor belt of the horizontal conveyor and is finally dried by the second blower mechanism. The drying effect is good.
