Description

Technical Field

[0001] The utility model relates to the technical field of chemical production equipment, in particular to a safety protection device for the production of pyridine chlorobromide. Background Art

[0002] Pyridine chlorobromide is an organic salt compound, which is formed by the combination of pyridine molecules and chlorobromate ions. When it is used in chemical production, the raw materials in the raw material tank need to be packaged into raw material barrels. Pyridine is a flammable, volatile and irritating organic compound. Chlorobromic acid is a strong acid with strong corrosiveness and severe irritation to the skin, eyes and respiratory tract. In the prior art, protective clothing and gas masks need to be worn for packaging.

[0003] During the filling process, pyridine and chlorobromic acid will continue to evaporate and overflow from the filling port. Although protective clothing is worn, being in a high-concentration harmful gas environment for a long time will greatly reduce the service life of the gas mask filter box. Once the gas mask filter box fails during use, the employee's life will be in danger. At the same time, the possibility of harmful gases spreading outward is increased. In addition, during the filling process, due to wearing protective clothing and gas masks, it is very easy to cause solvent splashing or raw material filling to overflow from the chemical barrel, corroding the ground or other production equipment. Therefore, a chlorobromic acid pyridine production safety protection device is needed to solve the above problems. Utility Model Content

[0008] As a preferred safety protection device for the production of pyridine chlorobromide of the utility model, a sealing ring is arranged on the top of the inner end surface of the sealing cover, and the sealing ring is a hollow annular rubber ring.

[0009] As a preferred safety protection device for the production of pyridine chlorobromide of the utility model, the bottom of the airflow channel is higher than the lower end surface of the guide funnel.

[0010] As a preferred safety protection device for the production of pyridine chlorobromide of the utility model, the sealing buoy includes a float, a connecting rod and a sealing plug, the float is located at the bottom of the connecting rod, the sealing plug is located at the top of the connecting rod, and the diameter of the sealing plug is equal to the inner diameter of the airflow channel, the outer end surface of the guide funnel is provided with a sliding hole, and the connecting rod passes through the sliding hole and is slidably connected to the guide funnel.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model cooperates with the purification mechanism and the guide mechanism to form negative pressure to draw the volatile harmful gas into the purification box through the air flow channel for purification, thereby reducing the risk of operators being exposed to harmful gas environments and improving operational safety.

DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 4 A safety protection device for the production of pyridine chlorobromide, comprising a raw material barrel 1 and a trolley 4, wherein a feeding port 101 is arranged at the upper end of the raw material barrel 1, a flow guide mechanism 2 is arranged in the feeding port 101, and a purification mechanism 3 is arranged on the trolley 4;

[0023] The flow guide mechanism 2 includes a flow guide funnel 210, a locking bolt 220 and a sealing buoy 230. The flow guide funnel 210 is inserted into the feeding port 101 and is slidably connected to the raw material barrel 1. An air flow channel 212 is provided on the outer end face of the side wall of the flow guide funnel 210. An exhaust port 213 is provided on the top of the air flow channel 212. The exhaust port 213 is connected to the purification mechanism 3 through a rubber tube. The sealing buoy 230 is located at the bottom of the air flow channel 212.

[0024] Furthermore, a sealing cover 211 is disposed on the outer end surface of the diversion funnel 210 , a screw hole 215 is disposed on the side surface of the sealing cover 211 , and a locking bolt 220 is inserted into the screw hole 215 and threadedly connected with the sealing cover 211 .

[0025] The locking bolt 220 is tightened to squeeze the outer end surface of the feeding port 101, thereby fixing the diversion funnel 210 and the sealing cover 211, and can adapt to raw material barrels 1 of different calibers within a certain range, thereby improving the application range of the equipment.

[0026] Furthermore, a sealing ring 216 is provided on the top of the inner end surface of the sealing cover 211 , and the sealing ring 216 is a hollow annular rubber ring.

[0027] When the sealing cover 211 is pressed downward, the sealing ring 216 covers the edge of the feeding port 101. At this time, tightening the tightening bolt can keep the diversion funnel 210 and the raw material barrel 1 sealed to prevent the raw material from leaking from the gap between the diversion funnel 210 and the feeding port 101.

[0028] Furthermore, the bottom of the airflow channel 212 is higher than the lower end surface of the guide funnel 210 .

[0029] Avoid excessive air pressure in the air flow channel 212, which would cause the raw materials flowing down the guide funnel 210 to be sucked into the purifier and corrode the purifier.

[0030] Furthermore, the sealing buoy 230 includes a float 231, a connecting rod 232 and a sealing plug 233. The float 231 is located at the bottom of the connecting rod 232, the sealing plug 233 is located at the top of the connecting rod 232, and the diameter of the sealing plug 233 is equal to the inner diameter of the airflow channel 212. The outer end surface of the guide funnel 210 is provided with a sliding hole 214, and the connecting rod 232 passes through the sliding hole 214 and is slidably connected to the guide funnel 210.

[0031] When the solution in the raw material barrel 1 is almost full, the float 231 floats upward under the buoyancy of the raw material solution, gradually approaches the air flow channel 212, and is sucked into the air flow channel 212 by suction to block the air flow channel 212. The excess solution in the funnel can no longer flow into the raw material barrel 1 under the action of air pressure. At this time, the locking bolt 220 is loosened so that the air in the raw material barrel 1 can be discharged from the diversion funnel 210. Since the connecting rod 232 has a certain length, there is still a certain capacity in the raw material barrel 1, so that the remaining raw materials in the diversion funnel 210 can be discharged into the raw material barrel 1.

[0032] Furthermore, the purification mechanism 3 includes a purification box 301 , an air filter 302 and a blower 303 . The air filter 302 is installed in the purification box 301 . The purification box 301 and the blower 303 are fixedly installed on the trolley 4 . The blower 303 is connected to the purification box 301 .

[0033] The blower 303 draws air to form a negative pressure at the bottom of the air flow channel 212, so that the volatile harmful substances are sucked into the purification box 301 and discharged after purification. Moreover, since the raw material barrel 1 is in a negative pressure state, the raw materials can flow into the raw material barrel 1 quickly, which greatly improves the packaging speed.

[0034] Furthermore, a slide groove 304 is provided on the front end surface of the purification box 301 , and the air filter element 302 is inserted into the slide groove 304 and is slidably connected with the purification box 301 .

[0035] The sliding connection structure allows the air filter element 302 to be quickly disassembled and installed, greatly improving the convenience of equipment maintenance.

[0036] When the device is in use, the guide funnel 210 is inserted into the feeding port 101 of the raw material barrel 1, and the relative positions of the locking bolt 220 and the sealing cover 211 are adjusted to make it fit with the outer end surface of the feeding port 101, and the guide funnel 210 is pressed downward to ensure that the sealing ring 216 on the inner end surface of the sealing cover 211 is tightly wrapped around the edge of the feeding port 101, and then the locking bolt 220 is tightened to ensure that the guide funnel 210 and the raw material barrel 1 form a sealed connection, and the blower 303 is turned on and started to work. The blower 303 starts to draw air, and a negative pressure is formed in the guide funnel 210 through the air flow channel 212, so that the volatile harmful gas is sucked into the purification box 301, and chlorobromic acid or pyridine raw materials are poured into the guide funnel 210. The pressure state helps the raw materials to flow into the raw material barrel 1 quickly and smoothly, thereby improving the packaging efficiency. As the liquid level rises, the float 231 in the sealing float 230 rises accordingly under the action of buoyancy. When the liquid level is close to being full, the float 231 is sucked into the air flow channel 212 and blocks the channel to prevent the raw materials from continuing to flow in. Due to the blockage of the air flow channel 212, the blower 303 will make an abnormal sound. Stop loading in time and shut down the blower 303. Short-term blockage of the air duct will not cause damage to the blower 303. Loosen the locking bolt 220 to discharge the air in the raw material barrel 1 so that the remaining raw materials can be smoothly introduced. After the liquid level stabilizes, remove the guide funnel 210, clean up any remaining raw materials, and properly store or replace the air filter element 302 for next use.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
