Description

Technical Field

[0001] This application relates to the field of refractory material production technology, and in particular to a closed feeding device that facilitates dust removal. Background Technology

[0002] Refractory materials are now defined as any material whose physical and chemical properties allow it to be used in high-temperature environments. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate industry, power industry, and other industrial fields. In the refractory material mixing and production process, to ensure production efficiency, feeding equipment is needed to transport the raw materials to the mixing equipment.

[0003] Currently, the refractory material production feeding equipment used in small factories mainly consists of a conveyor frame, a conveyor belt-type conveying mechanism installed on the conveyor frame, and movable support legs installed at the bottom of the conveyor frame. When using this type of feeding equipment, it is first moved to the refractory material mixing equipment, and the discharge port of the feeding equipment is located above the inlet of the refractory material mixing equipment. Then, the refractory material raw materials are directly put onto the conveyor belt on the conveyor mechanism so that the refractory material raw materials are fed into the mixing equipment while the conveyor belt is moving.

[0004] While existing refractory material production feeding equipment can feed refractory raw materials into the mixing equipment, the open structure of the feeding equipment's upper part and the feeding end, along with the gap between the feeding equipment's discharge port and the mixing equipment's inlet, results in a large amount of dust being scattered during the feeding process. This makes the surrounding environment of the equipment quite dirty and messy, and also makes it difficult to easily remove dust during the feeding process. Summary of the Invention

The screw sleeve is connected to the bottom end of the screw. The guide rod is installed on the side of the bottom end of the discharge hopper opposite to the screw.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of the refractory material production and feeding equipment currently used in small factories will be introduced first.

[0025] Currently, the refractory material production feeding equipment used in small factories mainly consists of a conveyor frame, a conveyor belt-type conveying mechanism installed on the conveyor frame, and movable support legs installed at the bottom of the conveyor frame. When using this type of feeding equipment, it is first moved to the refractory material mixing equipment, and the discharge port of the feeding equipment is located above the inlet of the refractory material mixing equipment. Then, the refractory material raw materials are directly put onto the conveyor belt on the conveyor mechanism so that the refractory material raw materials are fed into the mixing equipment while the conveyor belt is moving.

[0026] Please see Figures 1-4 This application discloses a closed-type feeding device for easy dust removal, comprising a conveyor frame 2, a driven roller 10 mounted on one side of the upper end of the conveyor frame 2, and a driving roller 12 mounted on the conveyor frame 2 below the driven roller 10. A conveyor belt 11 is fitted around the outer sides of the driving roller 12 and the driven roller 10. A motor 6 is mounted on the outer side of the conveyor frame 2 directly opposite the driving roller 12. A sealing cover 9 is mounted on the upper side of the conveyor frame 2, and a feeding hopper 7 is mounted at the inlet of the sealing cover 9. A feeding shielding assembly 14 is mounted on the feeding hopper 7, comprising a shielding brush 141, an opening and closing plate 142, a return spring 143, and an arc-shaped sliding rod 144. There are two opening and closing plates 142, symmetrically mounted on both sides of the upper part of the feeding hopper 7. Two arc-shaped sliding rods 144 are symmetrically mounted at the bottom end of each opening and closing plate 142. A return spring 143 is installed on the lower side of the arc-shaped slide bar 144 outside the bottom of the 142. The shielding brush 141 is installed on both sides of the feed inlet of the feed hopper 7. A discharge hopper 1 is installed at the discharge outlet of the sealing cover 9. A discharge shielding mechanism 13 is installed on the lower side of the discharge hopper 1. The discharge shielding mechanism 13 includes a second motor 131, a screw 132, a guide rod 133, a telescopic cover 134, a guide sleeve 135, a screw sleeve 136, and a linkage frame 137. The telescopic cover 134 is installed in the middle of the bottom end of the discharge hopper 1. The linkage frame 137 is connected to the bottom end of the telescopic cover 134. The second motor 131 is installed on the protruding edge of the bottom periphery of the discharge hopper 1. The screw 132 is connected to the power output end of the second motor 131. The screw sleeve 136 is connected to the bottom end of the screw 132. The guide rod 133 is installed on the side of the bottom end of the discharge hopper 1 opposite to the screw 132. The guide sleeve 135 is connected to the bottom end of the guide rod 133.

[0027] Specifically, when adding raw materials to the refractory material mixing equipment, the conveyor frame 2 is first moved to one side of the mixing equipment, with the lower side of the discharge hopper 1 facing the feed inlet of the mixing equipment. Then, under the action of motor 131, the screw 132 rotates, so that after the screw 132 rotates, the linkage frame 137 moves down under the guidance of the threaded drive and the guide rod 133. After the linkage frame 137 moves down, it will drive the telescopic cover 134 to extend until the linkage frame 137 contacts the upper part of the mixing equipment, so as to achieve the blocking between the discharge hopper 1 and the feed inlet of the mixing equipment. Then, the refractory material raw material bag is put into the feed hopper 7, using the bag The weight of the refractory material opens the hinged plate 142, allowing for convenient addition of refractory material raw materials to the conveyor belt 11. During the addition process, the hinged plate 142 contacts the refractory material raw material bag. At this time, most of the space between the hinged plates 142 is blocked by the raw material bag. A small amount of dust that drifts out from the gap between the refractory material raw material bag and the other two side walls of the feed hopper 7 will be blocked and collected by the shielding brush 141. The refractory material entering the conveyor belt 11 will fall directly into the refractory material mixing equipment through the unfolded telescopic cover 134 after being conveyed to the discharge hopper 1, thereby realizing the feeding of refractory material raw materials into the mixing equipment.

[0028] Please see Figure 1 and Figure 2 The top center of the sealing cover 9 is also connected to a dust suction pipe 8, and the feed hopper 7 and discharge hopper 1 are all welded to the sealing cover 9.

[0029] As one implementation method, the suction pipe 8 is connected to an external dust removal device, which can clean up the dust that is scattered while feeding materials. The welding fixing method makes the installation of the feed hopper 7 and the discharge hopper 1 more secure.

[0030] Please see Figure 2 and Figure 4 The opening and closing plate 142 is connected to the feed hopper 7 by a hinge, and the arc-shaped slide rod 144 is welded to the opening and closing plate 142. The arc-shaped slide rod 144 slides in cooperation with the side wall of the feed hopper 7.

[0031] As one implementation method, the hinge connection installation method can ensure that the opening and closing plate 142 can rotate conveniently relative to the side wall of the feed hopper 7. After the opening and closing plate 142 is closed, it can seal the opening of the feed hopper 7 and prevent dust from drifting out of the upper space of the conveyor belt 11.

[0032] Please see Figure 2 and Figure 4 The rotation center of the arc-shaped slide bar 144 coincides with the rotation center of the connecting hinge on the opening and closing plate 142.

[0033] In one implementation, the rotation center of the arc-shaped slide bar 144 is made to coincide with the rotation center of the connecting hinge on the opening and closing plate 142, which can ensure that the arc-shaped slide bar 144 can slide easily along the side wall of the feed hopper 7 when the opening and closing plate 142 rotates.

[0034] Please see Figure 2 and Figure 4 The arc-shaped slide bar 144 passes through the reset spring 143. One end of the reset spring 143 is welded to the opening and closing plate 142, and the other end of the reset spring 143 is welded to the side wall of the feed hopper 7.

[0035] In one implementation, the reset spring 143 can automatically rotate and reset the opening and closing plate 142 during the feeding process to close and block the opening of the feed hopper 7.

[0036] Please see Figures 1-3 The telescopic cover 134 is bonded to the discharge hopper 1 and the linkage frame 137. The second motor 131 is bolted to the discharge hopper 1 and connected to the screw 132 by a coupling.

[0037] In one implementation, the telescopic cover 134 is mainly used to cover the space between the discharge hopper 1 and the feed inlet of the mixing equipment, and the motor 131 is mainly used to provide power to the screw 132.

[0038] Please see Figure 1 and Figure 3 The screw 132 is threadedly connected to the screw sleeve 136, and the bottom end of the screw sleeve 136 is welded to the linkage frame 137.

[0039] In one implementation, after the screw 132 rotates under the action of the motor 131, the linkage block will move down conveniently under the action of threaded transmission.

[0040] Please see Figure 3 The top end of the guide rod 133 is bolted to the discharge hopper 1, the bottom end of the guide rod 133 is slidably fitted with the guide sleeve 135, and the bottom end of the guide sleeve 135 is welded to the linkage frame 137.

[0041] As one implementation method, the guide rod 133 and the guide sleeve 135 cooperate to ensure the stable lifting and lowering adjustment of the linkage frame 137 under the action of the screw 132.

[0042] Please see Figure 1 and Figure 2 Two support legs 1 3 are symmetrically installed on one side of the bottom end of the conveyor frame 2, and two support legs 2 5 are symmetrically installed on the other side of the bottom end of the conveyor frame 2. Both support legs 1 3 and support legs 2 5 are equipped with brakeable casters 4 at their bottom ends.

[0043] As one implementation method, support legs 3 and 5 can ensure the stable placement of the conveyor frame 2, while casters 4 can ensure the convenient movement of the entire equipment.

[0044] The specific working principle is as follows: When adding raw materials to the refractory material mixing equipment, the conveyor frame 2 is first moved to one side of the mixing equipment, and the lower side of the discharge hopper 1 is directly facing the feed inlet of the mixing equipment. Then, under the action of motor 131, the screw 132 is rotated so that after the screw 132 rotates, the linkage frame 137 moves down under the guidance of the threaded drive and the guide rod 133. After the linkage frame 137 moves down, it will drive the telescopic cover 134 to extend until the linkage frame 137 is in contact with the upper part of the mixing equipment, so as to achieve the blocking between the discharge hopper 1 and the feed inlet of the mixing equipment. Then, the dust suction pipe 8 is connected to the external dust removal equipment, and the refractory material raw material bag is put into the feed hopper 7. The weight of the bagged refractory material opens the opening plate 142, so as to facilitate the addition of refractory material raw materials to the conveyor belt 11. During the addition process, the opening plate 142... When the refractory material comes into contact with the raw material bag, most of the space opened between the opening and closing plates 142 is blocked by the raw material bag. The small amount of dust that drifts out from the gap between the raw material bag and the other two side walls of the feed hopper 7 will be blocked and collected by the shielding brush 141. The refractory material entering the conveyor belt 11 will fall directly into the refractory material mixing equipment through the unfolded telescopic cover 134 after being transported to the discharge hopper 1, thereby realizing the feeding of refractory material raw materials into the mixing equipment. Under the action of this feeding equipment, the refractory material raw materials are in a relatively sealed space from the time they are put into the feeding equipment to the time they are added to the mixing equipment. This effectively reduces the large amount of dust drifting during the feeding process, ensuring a clean environment around the equipment and facilitating the quick cleaning of dust drifting during the feeding process.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
