Description

Technical Field

[0001] The utility model relates to a conveyor, in particular to the structure of a feeding device for magnesium chloride. Background Art

[0002] The transportation of solid materials is an important unit operation in chemical production, and it is necessary to ensure efficiency and maintain the quality of materials. Traditional equipment for conveying solid materials includes: ① belt conveyor, which uses belt rollers or chains to drive materials; ② pneumatic conveyor, which uses closed pipes to use gas as power to transport materials; ③ bucket conveyor, which uses a circulating hopper to lift upward; ④ gravity conveyor, which relies on the material's own gravity to unload from top to bottom; ⑤ screw conveyor, which uses spiral blades to move materials horizontally or obliquely.

[0003] The reserves of magnesium chloride resources in the Chaerhan Salt Lake in Qinghai are about 4 billion tons, which can be used as inorganic raw materials for chemical, metallurgical, building materials, pharmaceutical and other industries. During production, a feeding device is needed to transport magnesium chloride from the storage yard to the packaging and processing equipment. The existing feeding device is a combination of a screw conveyor and a belt conveyor. The screw conveyor transports magnesium chloride to the belt conveyor over a long distance or at an angle, and then the belt of the belt conveyor is used to transport magnesium chloride to the feeding port of the packaging and processing equipment.

[0004] However, since magnesium chloride is a granular material that easily absorbs water and hardens, magnesium chloride clumps easily accumulate and clog the end of the screw conveyor, and cannot be transported to the belt. Utility Model Content

[0005] The utility model aims to solve the problem that the magnesium chloride is easy to agglomerate and accumulate, and is blocked when the existing feeding device for conveying magnesium chloride is used, and cannot be conveyed to the belt.

[0006] To achieve the above purpose, the utility model provides a feeding device for conveying magnesium chloride, comprising: a shell 13, a conical hopper 2, a plurality of feeding augers 12, a conveying augers 11, and a belt conveyor.

[0007] The shell 13 is a cube, with an upper side opened to form a material passing port 130 . The conical hopper 2 is wide at the top and narrow at the bottom, and is installed on the upper side of the material passing port 130 .

[0008] Each feeding auger 12 is arranged in parallel in the shell 13, one end of which is rotatably connected to the side wall of the shell 13 through a first bearing 122, and the other end passes through the side wall on the opposite side to be connected to the driving shaft of the first driving motor 121 arranged outside the shell 13.

[0009] The side of the housing 13 away from the first drive motor 121 bulges downward to form a pipe installation portion 133 , on which the second drive motor 111 is disposed. An end away from the second drive motor 111 extends outward to form a downward discharge port 14 .

[0010] The inner space of the pipeline installation part 133 serves as a conveying passage 131 , and a conveying auger 11 is installed therein.

[0011] The conveying auger 11 is located below the feeding auger 12 and is perpendicular to the feeding auger 12. One end of the conveying auger 11 is rotatably connected to the front side of the conveying channel 131 through the second bearing 112, and the other end is connected to the driving shaft of the second driving motor 111 through the second coupling.

[0012] The belt conveyor is located directly below the discharge port 14 .

[0013] Therefore, the staff turns on the first drive motor 121 and each second drive motor 111 and then operates the forklift to produce magnesium chloride from the material pile to the conical hopper 2.

[0014] The magnesium chloride will fall by gravity and enter the shell 13. After that, the magnesium chloride entering the shell 13 is pushed to the right by the feeding auger 12, falls into the conveying channel 131 at the right end of the shell 13, and is then pushed forward by the conveying auger 11, discharged from the discharge port 14 at the front end of the conveying channel 131 onto the belt of the belt conveyor, and is further transported by the belt to the magnesium chloride dissolution tank for subsequent processing.

[0015] Because during the simultaneous operation of the three feeding augers 12 and the conveying augers 11, the friction between the magnesium chloride and the spiral blades will lift the magnesium chloride, and then the magnesium chloride will fall by gravity, so that the magnesium chloride will be subjected to shear force and extrusion force at the same time, and the magnesium chloride lumps will be continuously crushed, which can prevent the magnesium chloride material from getting damp and hardening, and avoid the situation where the agglomerated magnesium chloride accumulates above the belt and cannot be transported to the belt.

[0016] Preferably, a grid plate for filtering is installed at the feed inlet of the conical hopper 2. The grid plate 21 can filter out impurities such as plastic bags and wooden wedges in the magnesium chloride.

[0017] Preferably, the side of the conical hopper 2 is provided with reinforcing ribs 22 for reinforcement. Therefore, the conical hopper 2 can be prevented from being deformed by the pressure applied by the magnesium chloride.

[0018] Preferably, the discharge end of the belt conveyor is connected to the magnesium chloride dissolving tank. The non-agglomerated magnesium chloride crushed by the feeding device can be dissolved more quickly, which can improve the dissolution efficiency.

[0019] Preferably, the first drive motor 121 and the second drive motor 111 are variable frequency motors connected to a PLC control system or a DCS remote control system. Therefore, the staff can control the rotation speed of the first drive motor 121 and the second drive motor 111 according to the actual situation of the magnesium chloride delivery amount, that is, the variable frequency speed regulation can be performed according to the size of the material delivery amount, which can further prevent the material from accumulating in the housing 13 or the delivery channel 131.

[0023] The following takes a feeding device equipped with three feeding augers to transport magnesium chloride from a stockpile to a dissolving tank as an example, and describes an embodiment of the utility model in detail in conjunction with the accompanying drawings. The following description is a concretization of the claims of the utility model.

[0024] Figure 1 The structure of the feeding device for conveying magnesium chloride is shown, as Figure 1 As shown, the feeding device for conveying magnesium chloride comprises: a housing 13, a conical hopper 2, three feeding augers 12, a conveying augers 11, and a belt conveyor (not shown in the figure).

[0025] like Figure 1 As shown, the housing 13 is a cube. Figure 3 The housing 13 is shown along Figure 1 The structure seen in the direction of arrow a, combined with Figure 3 The upper side of the shell 13 is opened to form a material passing port 130 .

[0026] like Figure 1 , 3 As shown, the shell 13 is a cube, the upper side of which is open to form a material passing port 130 , and the conical hopper 2 is wide at the top and narrow at the bottom, and is installed on the upper side of the material passing port 130 .

[0027] Each feeding auger 12 is arranged in parallel in the shell 13, one end of which is rotatably connected to the side wall of the shell 13 through a first bearing 122, and the other end passes through the side wall on the opposite side to be connected to the driving shaft of the first driving motor 121 arranged outside the shell 13.

[0028] The side of the housing 13 away from the first drive motor 121 bulges downward to form a pipe installation portion 133 , on which the second drive motor 111 is disposed. An end away from the second drive motor 111 extends outward to form a downward discharge port 14 .

[0029] The belt conveyor is located directly below the discharge port 14 (not shown in the figure), and the discharge end of the belt conveyor is connected to the magnesium chloride dissolving tank (not shown in the figure).

[0030] like Figure 1 As shown at the top, the conical hopper 2 is a quadrangular pyramid-shaped cylinder mounted on the discharge port 14 and narrowing downward.

[0031] The upper end of the conical hopper 2 is opened to form a feed port for feeding, and is provided with a grid plate 21 for filtering, which can filter out impurities mixed in the magnesium chloride, such as plastic bags, wooden wedges, etc., and can also break up larger magnesium chloride lumps.

[0032] The side of the conical hopper 2 is provided with reinforcing ribs 22 for reinforcement. Figure 1 As shown, in this embodiment, the reinforcing ribs 22 are made of angle steel and are laterally arranged along the side of the conical hopper 2 to prevent the conical hopper 2 from being deformed by the pressure exerted by magnesium chloride.

[0033] Combination Figure 1 and Figure 3 It can be seen that the lower part of the conical hopper 2 is open and communicated with the feeding port 130 on the upper side of the shell 13 , that is, the magnesium chloride entering the conical hopper 2 enters the shell 13 through the feeding port 130 after being filtered by the grid plate 21 .

[0034] Figure 2 is along Figure 1 The sectional view taken along line AA in FIG. 1 shows the internal structure of the housing. Figure 2 As shown, three feeding augers 12 are arranged in the housing 13, and a conveying augers 11 are arranged in the conveying channel 131. The structures of the conveying augers 11 and the feeding augers 12 are basically the same, and both are composed of spiral blades and a shaft body.

[0035] See also Figure 2 On the lower side, three first drive motors 121 are located on the left side outside the housing 13. One end of each feeding auger 12 is rotatably connected to the right side wall of the housing 13 through a first bearing 122, and the other end is connected to the drive shaft of the first drive motor 121 through a first coupling. The center lines of each feeding auger 12 are parallel to each other, and the distance between them is equal.

[0036] See also Figure 2On the right side, the conveying auger 11 is arranged in the conveying channel 131, and the driving shaft of the second driving motor 111 is arranged outside and behind the conveying channel 131. One end of the conveying auger 11 is rotatably connected to the front side of the conveying channel 131 through the second bearing 112, and the other end is connected to the driving shaft of the second driving motor 111 through the second coupling. The center line of the conveying auger 11 is perpendicular to the center line of the feeding auger 12.

[0037] Combination Figure 3 It can be seen from the positional relationship between the first drive motor 121 and the second drive motor 111 that the conveying auger 11 is located below the feeding auger 12 .

[0038] The first drive motor 121 and each second drive motor 111 are variable frequency motors, which are connected to a PLC control system or a DCS remote control system (not shown in the figure).

[0039] The method of using the feeding device is:

[0040] First, the staff turns on the first drive motor 121 and each second drive motor 111 , and then operates the forklift to move the magnesium chloride from the stockpile to the conical hopper 2 .

[0041] After the magnesium chloride is filtered out of impurities such as plastic bags and wooden wedges by the grid plate 21 and decomposed into small pieces, it is gathered by the conical hopper 2 and evenly enters the shell 13 through the feed port 130 .

[0042] Afterwards, the magnesium chloride entering the shell 13 is pushed to the right by the feeding auger 12, falls into the conveying channel 131 at the right end of the shell 13, and is then pushed forward by the conveying auger 11, discharged from the discharge port 14 at the front end of the conveying channel 131 onto the belt of the belt conveyor, and is further transported by the belt to the magnesium chloride dissolution tank for subsequent processing.

[0043] When the three feeding augers 12 and the conveying augers 11 are running simultaneously, the friction between the magnesium chloride and the spiral blades will lift the magnesium chloride up, and then the magnesium chloride will fall down by gravity, so that the magnesium chloride will be subjected to shear force and extrusion force at the same time, and the magnesium chloride lumps will be continuously crushed, thereby preventing the magnesium chloride material from getting damp and hardening, and preventing the agglomerated magnesium chloride from accumulating above the belt and being unable to be transported to the belt.

[0044] During the use of the feeding device, the staff can control the rotation speed of the first drive motor 121 and the second drive motor 111 according to the actual situation of the magnesium chloride conveying amount, that is, the variable frequency speed can be adjusted according to the size of the material conveying amount, which can further prevent the material from accumulating in the shell 13 or the conveying channel 131.

[0045] In summary, the utility model utilizes a plurality of mutually parallel feeding augers 12 and a vertical conveying augers 11 to convey magnesium chloride, and continuously crushes magnesium chloride agglomerates, thereby preventing the magnesium chloride material from being damp and hardened and being unable to be conveyed to the belt.
