These raw materials are diverse, usually divided into two categories: organic chemical raw materials and inorganic chemical raw materials. Organic chemical raw materials such as alkanes, alkenes and their derivatives, while inorganic chemical raw materials are mainly derived from sulfur, sodium, phosphorus, potassium, calcium and other chemical minerals, as well as natural resources such as coal, oil and natural gas. Chemical raw materials are widely used in various industries, such as plastics, rubber, paint, fertilizer, medicine and cosmetics, etc. They play a key role in these industries, driving the growth and development of related markets.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a raw material storage device for chemical raw material production, including a storage tank 1, a plastic handle 2 connected to the storage tank 1, a discharge port 3 at the bottom of the storage tank 1, a sealing plug 4 inside the discharge port 3, and a discharge mechanism 5 on the storage tank 1. The discharge mechanism 5 includes a sealing cover 501 connected to the upper end of the storage tank 1 and a piston push plate 505 movably installed inside the storage tank 1. A sealing ring 507 is installed on the piston push plate 505, and an air inlet 502 is opened on the sealing plug 4. A limiting mechanism 6 is provided between the sealing cover 501 and the piston push plate 505. Through the cooperation of the discharge mechanism 5 and the limiting mechanism 6, the raw material in the storage tank 1 can be completely squeezed out, preventing the raw material from remaining in the storage tank 1 and reducing the waste of raw material.

[0022] like Figure 2 and Figure 3 As shown, the unloading mechanism 5 includes a sealing barrel cover 501 connected to the upper end of the storage barrel body 1 and a piston push plate 505 movably installed inside the storage barrel body 1. A sealing ring 507 is installed on the piston push plate 505. An air inlet 502 is opened on the sealing plug 4. A one-way valve 503 is provided in the air inlet 502. An inlet and outlet through hole 504 is opened in the middle of the sealing barrel cover 501. An installation groove 506 is opened on the side wall of the piston push plate 505. The sealing ring 507 is installed on the piston push plate 505 through the installation groove 506. The sealing barrel cover 501 is threaded and is connected to the storage barrel body 1 by the thread. A sealing strip is provided at the connection between the sealing barrel cover 501 and the storage barrel body 1.

[0023] Specifically, compressed gas can be injected into the storage tank 1 through the air inlet 502. When the piston push plate 505 is no longer restricted, the compressed gas in the storage tank 1 will begin to expand. This expansion will push the piston push plate 505 downward, thereby ensuring that the raw material in the storage tank 1 is completely squeezed out. This design can effectively prevent the raw material from remaining in the storage tank 1, thereby reducing the waste of raw material.

[0024] like Figure 2 and Figure 4 As shown, the limiting mechanism 6 includes a threaded positioning sleeve 604 fixedly installed in the middle position of the sealing barrel cover 501 and a threaded connecting sleeve 606 fixedly installed in the middle position of the piston push plate 505. A limiting screw 603 is connected inside the threaded positioning sleeve 604. The surface of the limiting screw 603 is provided with mating threads 605. A slot 602 is opened at the upper end of the limiting screw 603. A sealing end cover 601 is installed on the upper end of the threaded positioning sleeve 604. The sealing end cover 601 is provided with threads. The sealing end cover 601 is connected to the upper end of the threaded positioning sleeve 604 by threads. A sealing strip is provided at the connection between the threaded positioning sleeve 604 and the sealing end cover 601.

[0025] Specifically, after the sealing lid 501 is closed, the next step is to screw the limiting screw 603 into the threaded connecting sleeve 606. The purpose of this action is to firmly fix the piston push plate 505 under the sealing lid 501. Then, a screwdriver can be inserted into the slot 602. After the screwdriver is tightly connected to the slot 602, the limiting screw 603 can be rotated. During the rotation of the limiting screw 603, the limiting screw 603 will gradually disengage from the threaded connecting sleeve 606. Once the limiting screw 603 is completely disengaged from the threaded connecting sleeve 606, the piston push plate 505 will lose its original restriction and can move freely.

[0026] Working principle: During filling, the chemical raw materials are first poured into the storage tank 1, but not completely filled, leaving a certain space at the top. Then, the piston push plate 505 is placed at the top of the storage tank 1. After the piston push plate 505 is in place, the sealing cap 501 is closed. After closing the sealing cap 501, the limiting screw 603 is screwed into the threaded connecting sleeve 606. After the limiting screw 603 is screwed into the threaded connecting sleeve 606, the sealing end cap 601 is closed. After closing the sealing end cap 601, compressed gas is injected into the storage tank 1 through the air inlet 502. During unloading, the sealing plug 4 is opened first. Afterwards, the sealing end cover 601 can be opened. After opening the sealing end cover 601, a screwdriver can be connected to the slot 602. After the screwdriver is connected to the slot 602, the limiting screw 603 can be rotated. After rotating the limiting screw 603, it will disengage from the threaded connecting sleeve 606. After the limiting screw 603 disengages from the threaded connecting sleeve 606, the piston push plate 505 will lose its restraint. After the piston push plate 505 loses its restraint, the compressed gas in the storage tank 1 will expand, thereby pushing the piston push plate 505 downward. When the piston push plate 505 moves downward, it will completely squeeze out the raw material in the storage tank 1, preventing the raw material from remaining in the storage tank 1 and reducing the waste of raw material.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
