[0022] Specifically, please refer to Figures 1 to 4 Figure 1 This is a schematic diagram of the overall cross-sectional structure of a feeding device for desulfurized gypsum provided in an embodiment of the present application. Figure 2 for Figure 1 A magnified view at point A. Figure 3 This is a schematic diagram of the overall front view of the feeding device for desulfurized gypsum provided in an embodiment of the present application in another state. Figure 4A schematic diagram of the local structure of the baffle provided in the embodiment of the present application. The feeding device 100 applied to desulfurized gypsum includes a storage hopper 110 and a weighing belt conveyor 120 arranged below the storage hopper 110. The desulfurized gypsum is stored in the storage hopper 110. Usually, a hoist is arranged on one side of the storage hopper 110 to transport the desulfurized gypsum and store it in the storage hopper 110. During use, the desulfurized gypsum is fed from the storage hopper 110 to the weighing belt conveyor 120, and the weighing belt conveyor 120 further transports the desulfurized gypsum to the corresponding equipment. A feeding bin 130 is arranged at the bottom of the storage hopper 110, and the feeding bin 130 is used to transport the desulfurized gypsum in the storage hopper 110 to the weighing belt conveyor 120. An electromagnetic gate valve 140 is provided between the feeding bin 130 and the storage hopper 110. The electromagnetic gate valve 140 is used to control the communication state between the storage hopper 110 and the main body of the feeding bin 130. When the electromagnetic gate valve 140 is opened, the desulfurized gypsum in the storage hopper 110 will fall into the main body of the feeding bin 130. The feeding bin 130 includes a bin body 131. A first rotating shaft 132 is provided at the middle of the bottom end of the bin body 131. One side of the first rotating shaft 132 is connected to the bottom of the bin body 131 through a guide plate 133 sealing cover. The other side of the first rotating shaft 132 forms a discharge port 134. Through the above arrangement, the discharge port 134 is located at a half side position of the lower end of the feeding bin 130 body. In order to make the discharge process smoother, the guide plate 133 can be tilted. A material baffle plate 135 is rotatably provided on the first rotating shaft 132, and the first rotating shaft 132 is rotatably connected to the middle part of the material baffle plate 135. When the equipment is in a stopped state, under the action of the counterweight component 150, the material baffle plate 135 is pulled downward by the counterweight component 150, and one end of the material baffle plate 135 located at the discharge port 134 will tilt upward and block the discharge port 134 to prevent dust in the bin body 131 from spilling out. One end of the baffle plate 135 located below the discharge port 134 is coaxially connected to a rotating drum 136a through a second rotating shaft 136, and the bottom of the rotating drum 136a protrudes below the baffle plate 135. When the electromagnetic gate valve 140 is opened, the desulfurized gypsum in the storage hopper 110 will fall into the feeding bin 130, and the desulfurized gypsum will fall above the baffle plate 135 after being drained by the drainage plate 133. When a certain amount of desulfurized gypsum accumulates above the baffle plate 135, the baffle plate 135 will turn downward along the first rotating shaft 132 and remain tilted (such as Figure 3), the drum 136a is in contact with the weighing belt conveyor 120. After the weighing belt conveyor 120 is turned on, the drum 136a rotates with the weighing belt conveyor 120 to reduce the friction on the contact surface. The desulfurized gypsum will further fall onto the weighing belt conveyor 120 through the drainage of the baffle plate 135. The baffle plate 135 is located at one end of the drainage plate 133 and is provided with a counterweight component 150. The counterweight component 150 provides a certain pulling force for the end of the baffle plate 135, so that the baffle plate 135 can automatically flip upward under certain working conditions and re-block the discharge port 134 (such as Figure 1 , Figure 2 A vibration motor 137 matching the baffle plate 135 is provided at the bottom of the guide plate 133. When the baffle plate 135 is turned over, the vibration end of the vibration motor 137 will contact the baffle plate 135, so that the vibration motor 137 drives the baffle plate 135 to vibrate, which is convenient for material dropping.

[0023] As can be seen from the above, in the embodiment of the present application, by setting a feeding bin 130 at the bottom of the storage hopper 110, and setting a baffle plate 135 at the bottom of the feeding bin 130, and setting a first rotating shaft 132 at the top of the baffle plate 135 to hinge the baffle plate 135 at the bottom of the feeding bin 130, so that after the material falling on the baffle plate 135 reaches a certain weight, the baffle plate 135 can rotate along the first rotating shaft 132 by itself and contact the weighing belt conveyor 120 through the rotating drum 136a. At this time, the desulfurized gypsum slowly falls on the weighing belt conveyor 120 under the guidance of the baffle plate 135 in an inclined state, which will greatly reduce the dust phenomenon caused by the free fall of the desulfurized gypsum. In the embodiment of the present application, by setting the rotating drum 136a, the contact between the baffle plate 135 and the weighing belt conveyor 120 is changed from sliding friction to rolling friction, thereby greatly reducing friction and avoiding belt conveyor wear. The present application also provides a counterweight block 152 so that when the material above the baffle plate 135 is reduced, the baffle plate 135 can flip upward and reset to block the feed opening 134 again under the action of the counterweight block 152 to prevent the dust in the bin body 131 from escaping to the outside.

[0024] In some embodiments, a wear pad 135a is disposed on one side of the top of the baffle plate 135, and the wear pad 135a corresponds to the vibration motor 137. In the embodiment of the present application, through the above arrangement, when the baffle plate 135 tilts and flips, the wear between the baffle plate 135 and the vibration motor can be avoided.

[0025] In some embodiments, a flange component 160 is included, and the flange component 160 includes a first flange connected to the bottom of the storage hopper 110 and a second flange connected to the top of the feeding bin 130, and the first flange and the second flange are connected by a flange. In the embodiment of the present application, through the above arrangement, it is convenient to connect the storage hopper 110 and the feeding bin 130 as a whole, and it is easy to disassemble, and it is convenient to replace and clean.

[0026] In some embodiments, the end of the material blocking plate 135 close to the rotating drum 136a forms an arc-shaped abutment end 135a. In the embodiment of the present application, through the above arrangement, the arc-shaped abutment end 135a can prevent the material blocking plate 135 from contacting the weighing belt conveyor 120 and further causing wear when the material blocking plate 135 tilts downward.

[0027] In some embodiments, the counterweight component 150 includes an installation box 151 disposed at the bottom of the baffle plate 135, the bottom wall of the installation box 151 gradually tilts upward from the feed port 134 to the guide plate 133 and forms an opening, a counterweight block 152 is disposed in the installation box 151, and the opening is used to place the counterweight block 152. In the embodiment of the present application, the material and quality of the counterweight block 152 can be selected and adjusted according to actual conditions. Through the above arrangement, the operator can conveniently place or take out the counterweight block 152 from the opening by holding the counterweight block 152 in the installation box 151, and because the installation box 151 has a certain inclination angle, the installation block can be prevented from sliding outward.

[0028] In some embodiments, there are multiple installation boxes 151, and multiple installation boxes 151 are arranged at equal intervals at the bottom of the baffle plate 135. In the embodiment of the present application, through the above arrangement, multiple counterweight blocks 152 can be prevented at the same time, and the adjustment of the weight of the counterweight component 150 will be more convenient and precise.

[0029] In some embodiments, an anti-drop protrusion 153 is provided on one side of the inner bottom wall of the installation box 151 near the opening. In the embodiment of the present application, through the above arrangement, since the counterweight 152 itself is affected by gravity, its bottom will always be in contact with the inner bottom wall of the installation box 151, and the anti-drop protrusion 153 can further prevent the counterweight 152 from sliding out along the opening under the influence of the vibration motor 137.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
