DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a solid material loading platform for chemical production provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the connection structure of the storage hopper, discharge pipe, dredging rod and other components shown; Figure 3 It is a schematic diagram of the connection structure of the storage hopper, the longitudinal through hole, the transverse through hole, the discharge pipe, the second sealing cover, the dredging rod and other components; Figure 4 It is a schematic diagram of the connection structure of the storage hopper, longitudinal through hole, transverse through hole, discharge pipe, flexible curtain, dredging rod and other components. The solid material loading platform for chemical production includes: a hanging platform 1, a storage hopper 2, a hanging scale 3 and at least three supporting legs 4;

[0022] There are at least three supporting legs 4, and four are used as an example in this embodiment. The hanging platform 1 is fixedly connected to the top of the four supporting legs 4 to form a stable supporting structure. A hook 15 is fixedly connected at the center position below the hanging platform 1, and the hanging scale 3 is hung on the hook 15. The storage hopper 2 is hung on the hook 301 of the hanging scale 3 through the iron chain 5, so that the hanging scale 3 can weigh the storage hopper 2 in real time, and then the loading amount can be accurately controlled during the loading process through the reading of the hanging scale 3. In order to improve the force stability of the supporting structure, the hanging scale 3 is hung at the center position below the hanging platform 1. The discharge port 201 of the storage hopper 2 is provided with a first sealing cover 18, and the first sealing cover 18 is threadedly connected to the storage hopper 2; when charging the storage hopper 2, the first sealing cover 18 is covered; when loading, the first sealing cover 18 can be opened.

[0023] A support rod 6 is fixedly connected inside the storage hopper 2, and one end of the support rod 6 is fixedly connected to the inner wall of the storage hopper 2; the other end of the support rod 6 is rotatably connected to a dredging rod 8 through a universal ball joint 7. One end of the dredging rod 8 extends out of the discharge port 201 of the storage hopper 2. When the discharge port 201 of the storage hopper 2 is blocked, the operator holds the dredging rod 8 with one end exposed at the discharge port 201 of the storage hopper 2, and rotates the dredging rod 8 to stir the blocked material at the discharge port 201 of the storage hopper 2, thereby clearing the blockage.

[0024] In some other implementations of this embodiment, a plurality of conical dredging teeth 21 are fixedly connected to the dredging rod, and the plurality of dredging teeth 21 are arranged in a row along the axis of the dredging rod. The dredging teeth 21 can increase the contact area between the dredging rod 8 and the solid material, thereby increasing the stirring range of the dredging rod 8 and improving the dredging efficiency.

[0025] In some other embodiments of the present embodiment, the discharge port 201 end of the storage hopper 2 is fixedly connected with a discharge pipe 9 for guiding the material, and the material in the storage hopper 2 is poured out from the discharge pipe 9. Taking the cylindrical discharge pipe 9 as an example, the discharge pipe 9 is provided with longitudinal through holes 10 along the axial direction and transverse through holes 11 along the circumferential direction that are staggered with each other. The dredging rod 8 is L-shaped, one end of the L-shaped dredging rod 8 is rotatably connected to the support rod 6 through a universal ball joint 7, and the other end of the L-shaped dredging rod 8 extends from the longitudinal through hole 10 or the transverse through hole 11, and the end of the dredging rod 8 extending from the discharge port 201 can move within the area specified by the longitudinal through hole 10 and the transverse through hole 11 to achieve the dredging operation. By setting the discharge pipe 9 to guide the solid material, it is possible to avoid the end of the dredging rod 8 extending from the discharge port 201 from being contaminated with solid material. When the operator holds the end of the dredging rod 8 extending from the discharge port 201, it will not be contaminated with solid material, which is conducive to reducing the risk of use. Especially when the solid material is a corrosive material, providing the discharge pipe 9 can effectively protect the operator's hands.

[0026] In some other implementations of the present embodiment, an external thread 19 is provided on the outer peripheral surface of the discharge pipe 9; the discharge pipe 9 is equipped with a second sealing cover 20, the second sealing cover 20 includes a threaded portion 2001 which is sleeved on the discharge pipe 9 by engaging with the external thread 19 and a dredging rod accommodating portion 2002 for accommodating the portion of the dredging rod 8 extending out of the discharge port 201; a dredging rod insertion hole 2003 is provided on the second sealing cover 20, the dredging rod insertion part 2003 is located on the threaded portion 2001, and the remaining portion of the dredging rod insertion hole 2003 is located on the dredging rod accommodating portion 2002; the second sealing cover 20 is put on the discharge pipe 9 in a way that the dredging rod insertion hole 2003 is opposite to the dredging rod 8, and the second sealing cover 20 is rotated until the threaded portion 2001 is threadedly connected to the discharge pipe 9, so that the outlet of the discharge pipe 9 can be sealed.

[0027] In some other implementations of this embodiment, one end of the dredging rod 8 extending out of the discharge port 201 of the storage hopper 2 is fixedly connected to a ball handle 14, which is convenient for the operator to hold the dredging rod 8 tightly when dredging the blockage. The ball handle 14 is made of a flexible resin material, and a friction protrusion strip 17 is fixedly connected to the outer surface of the ball handle 14 to increase the friction force of holding the ball handle 14.

[0028] In some other implementations of this embodiment, the storage hopper 2 is provided with an observation window 12 for observing the remaining amount of the material. The observation window 12 can be made of organic glass. The observation window 12 is provided with a scale line 16 for reminding to add material. When the remaining amount of material in the storage hopper 2 reaches the scale line 16, it is urgent to add material to the storage hopper 2.

[0029] In some other implementations of this embodiment, a flexible curtain 13 is provided on both the longitudinal through hole 10 and the transverse through hole 11 to prevent the solid powder from overflowing. The flexible curtain 13 can be a flexible plastic curtain made of polyurethane material. The flexible curtain 13 is fixedly connected to one side of the longitudinal through hole 10, and the flexible curtain 13 covers the longitudinal through hole 10; similarly, the flexible curtain 13 covering the longitudinal through hole 10 is fixedly connected to one side of the longitudinal through hole 10. The working principle of the flexible curtain 13 is explained by taking the dredging rod 8 extending through the longitudinal through hole 10 as an example. The flexible curtain 13 on the longitudinal through hole 10 is lifted up, and the closer to the dredging rod 8, the greater the degree of lifting; at this time, although the flexible curtain 13 cannot completely prevent the leakage of solid materials, it still has a certain function of preventing the leakage of solid materials; at this time, the flexible curtain 13 covering the longitudinal through hole 10 can completely prevent the solid materials from leaking from the longitudinal through hole 10. Therefore, the provision of the flexible barrier curtain 13 can effectively reduce the leakage of solid materials from the longitudinal through hole 10 and the transverse through hole 11 to the end of the dredging rod 8 extending from the discharge port 201, further improving the operator's safety.

[0030] The working principle of the solid material feeding platform for chemical production provided by the utility model is as follows:

[0031] The hanging scale 3 weighs the storage hopper 2 in real time. For one-time feeding, the reading of the hanging scale 3 is sufficient; for batch feeding, the feeding amount of the batch can be controlled according to the difference between the previous reading and the next reading.

[0032] Compared with the related art, the solid material loading platform for chemical production provided by the utility model has the following beneficial effects:

[0033] The utility model provides a solid material feeding platform for chemical production, which is composed of a hanging platform 1, at least three supporting legs 4 and a hanging scale 3 hanging below the platform to form a weighing mechanism; by hanging the storage hopper 2 on the hanging scale 3, the storage hopper 2 is weighed in real time, thereby realizing accurate control of the feeding amount. By limiting the hanging scale 3 to be hung at the center position below the platform, the force stability of the supporting structure can be improved. When the discharge port 201 of the storage hopper 2 is blocked, the operator holds the unblocking rod 8 exposed at one end of the discharge port 201 of the storage hopper 2, and rotates the unblocking rod 8 to stir the blocked material at the discharge port 201 of the storage hopper 2, thereby unblocking the blockage.
