Abstract

The utility model belongs to the technical field of chemical barrels, and is particularly a chemical barrel for the production of expandable polystyrene, comprising a barrel body and a leakproof component. The leakproof component is arranged in an internal cavity at the upper port of the barrel body. The sealing ring arranged at the edge of the sealing plate of the leakproof component does not conflict with the inner wall of the barrel body in the initial state. The sealing plate is slidably connected to a connecting rod arranged on a mounting frame and conflicts with the lower end of a reset spring. The mounting frame is fixedly connected to the inner wall at the barrel mouth. The lower end of the connecting rod is rotatably connected to a conflict seat, and the lower part of the conflict seat is fixedly connected to a gravity ball through a connecting rod. The utility model installs a leakproof component at the barrel mouth of the barrel body. When the barrel body is tilted, the plug body structure formed by the combination of the plug plate and the plug ring conflicts with the barrel wall, effectively blocking the barrel mouth, thereby preventing the chemical raw materials in the barrel body from leaking out. At the same time, after the barrel body is straightened, the plug body structure is reset to cancel the blockage of the barrel mouth. The structure is simple and easy to use.

Description

Technical Field

[0001] The utility model relates to the technical field of chemical barrels, in particular to a chemical barrel for the production of expandable polystyrene. Background Art

[0002] Expandable polystyrene (PS) includes ordinary expandable polystyrene, expanded expandable polystyrene (EPS), high impact expandable polystyrene (HIPS) and syndiotactic expandable polystyrene (SPS). Ordinary expandable polystyrene resin is non-toxic, odorless, colorless transparent particles, glass-like brittle materials, and its products have extremely high transparency, light transmittance of more than 90%, good electrical insulation performance, easy coloring, good processing fluidity, good rigidity and good chemical corrosion resistance. The disadvantages of ordinary expandable polystyrene are brittleness, low impact strength, easy stress cracking, poor heat resistance and inability to resist boiling water.

[0003] In the production process of expandable polystyrene, the blanks and scraps are placed in chemical barrels to facilitate the quick and flexible transportation of the blanks and scraps. However, when the chemical barrels are used to hold the blanks and scraps, there is unused chemical liquid inside after the chemical barrels are opened. If the chemical barrels are accidentally knocked over, the chemical liquid will overflow from the discharge port of the chemical barrels. If the overflowed chemical liquid is not handled in time, it will not only pollute the environment but also cause great difficulty in cleaning, which is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model proposes: a chemical barrel for expandable polystyrene production, including a barrel body 1 and a leak-proof component 3, the leak-proof component 3 is arranged in the internal cavity at the upper end of the barrel body 1, so that when the barrel body 1 is tipped over, the barrel mouth is sealed by the leak-proof component 3, thereby effectively preventing chemical raw materials from leaking out of the barrel mouth, and effectively storing chemical raw materials. The sealing ring 302 arranged at the edge of the sealing plate 301 of the leak-proof component 3 does not conflict with the inner wall of the barrel body 1 in the initial state, the sealing plate 301 is slidably connected to the connecting rod 303 arranged on the mounting frame 304, and conflicts with the lower end of the reset spring 305, the mounting frame 304 is fixedly connected to the inner wall at the barrel mouth, the lower end of the connecting rod 303 is rotatably connected to the conflict seat 306, and the conflict seat 3 06 is fixedly connected to the lower part with a gravity ball 308 through a connecting rod 307. When tipping, the gravity ball 308 rotates at the lower end of the connecting rod 303 through the connecting rod 307 with the abutment seat 306 under the action of gravity. During the rotation, the abutment seat 306 pushes the blocking plate 301 to slide on the connecting rod 303, and the blocking plate 301 with the blocking ring 302 tightly contacts the inner wall of the barrel mouth, stably blocking the part to prevent chemical raw materials from leaking from the barrel body 1. At the same time, the return spring 305 mounted on the connecting rod 303 is compressed during the sliding process of the blocking plate 301, so that after the tipped barrel body 1 is reset, when the abutment seat 306 cancels the push on the blocking plate 301, the return spring 305 pushes the blocking plate 301 to slide and reset on the connecting rod 303, canceling the blockage of the barrel mouth.

[0023] like Figure 2As shown, in some embodiments, a sliding sleeve 3011 integrally arranged at the middle part of the sealing plate 301 is slidably connected to the rod body of the connecting rod 303, so as to improve the sliding stability of the sealing plate 301 on the connecting rod 303, ensure smooth adjustment of the position of the sealing plate 301, and achieve sealing at the barrel mouth. Sealing rings are arranged on the inner wall of the sliding sleeve 301 at equal intervals, and the sealing rings slide against the connecting rod 303 to seal the gap between the two, thereby preventing chemical raw materials from leaking from this part and improving the stability of the sealing.

[0024] like Figure 2 and Figure 3 As shown, in some embodiments, the plug-in lip plate integrally arranged at the edge of the sealing plate 301 is plugged into the connecting groove 3021 provided on the sealing ring 302, so that the sealing ring 302 can be stably installed on the sealing plate 301, so that the two can be stably used together, and at the same time, a soft sealing ring is formed at the edge of the sealing plate 301, so that it contacts the inner wall at the barrel mouth, thereby achieving stable and effective sealing of this part, and effectively preventing the barrel body 1 from tipping over and leaking chemical raw materials. The outer side surface of the sealing ring 302 is arranged as an arc-shaped contact surface 3022, and a deformation cavity 3023 is opened near the contact surface 3022 inside the sealing ring 302, so that after the sealing ring 302 contacts the inner wall of the barrel mouth, under the action of extrusion, the contact surface 3022 is deformed under the action of the deformation cavity 3023, thereby expanding the contact surface between the sealing ring 302 and the inner wall of the barrel body 1, and improving the stability of the plugging.

[0025] like Figure 2 As shown, in some embodiments, the upper end of the connecting rod 303 is fixedly inserted into the connecting seat 3041 provided at the middle part of the mounting frame 304, and an anti-dropping pin is inserted at the connecting part of the connecting rod 303 and the connecting seat 3041, so as to facilitate the upper end of the connecting rod 303 to be stably connected to the mounting frame 304, ensure the stable cooperation of the two, and provide a stable track for the blocking plate 301 to slide up and down, and the lower end of the connecting rod 303 is rotatably connected to the deflection groove 3061 provided on the abutment seat 306 through the rotating shaft, so as to facilitate the smooth rotation of the abutment seat 306 at the lower end of the connecting rod 303, and push the blocking plate 301 against it during the rotation process, so that the blocking plate 301 slides on the connecting rod 303, and the position debugging operation is completed;

[0026] The lower end of the connecting rod 303 is connected to the eccentric position of the disc-shaped abutment seat 306 to form an eccentric wheel structure. In the initial state, the edge of the abutment seat 306 has the smallest abutment displacement on the blocking plate 301, and the abutment seat 306 rotates 90 degrees. The pushing displacement of the blocking plate 301 is the largest, and the distance between the blocking ring 302 at the edge of the blocking plate 301 and the inner wall of the barrel body 1 is less than the maximum displacement that the blocking plate 301 can be pushed, thereby ensuring that the abutment seat 306 can push the blocking plate 301 with the blocking ring 302 to fit tightly to the inner wall of the barrel body 1, and block the barrel mouth of the barrel body 1, thereby preventing the chemical raw materials inside from leaking out when the barrel body 1 is tipped over. The reset spring 305 mounted on the connecting rod 303 is supported between the blocking plate 301 and the mounting frame 304, so that the abutment seat 306 can push the blocking plate 301 to fit tightly to the inner wall of the barrel body 1 with the blocking ring 302, and block the barrel mouth of the barrel body 1, thereby preventing the chemical raw materials inside from leaking out when the barrel body 1 is tipped over. The reset spring 305 mounted on the connecting rod 303 is supported between the blocking plate 301 and the mounting frame 304, so that the reset spring 305 can push the blocking plate 301 to fit tightly to the inner wall of the barrel body 1 with the blocking ring 302, and block the barrel mouth of the barrel body 1, and prevent the chemical raw materials inside from leaking out when the barrel body 1 is tipped over. 1 slides while compressing the return spring 305, and then after the abutment seat 306 is reset, the return spring 305 can push the blocking plate 301 to reset, canceling the blockage of the barrel mouth of the barrel body 1, and the connecting rod 303 is located on the rod body of the upper part of the blocking plate 301 and is plugged with a limit pin 309. When it is necessary to dump the chemical raw materials in the barrel body 1, the barrel cover 2 is opened, and the limit pin 309 is plugged into the limit hole provided on the connecting rod 303, and the blocking plate 301 is limited and fixed to prevent the blocking plate 301 from sliding to block the barrel mouth when the chemical raw materials are dumped, thereby ensuring stable use.

[0027] like Figure 1 As shown, in some embodiments, a barrel cover 2 is threadedly connected to the upper barrel opening of the barrel body 1 to facilitate sealing the barrel opening of the barrel body 1 and thus stably storing chemical raw materials.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
