Description

Technical Field

[0001] This utility model relates to the field of pipe valve unblocking technology, and in particular to a device for unblocking bottom valves and pressurizing pipelines. Background Technology

[0002] Chemical processing plants frequently use equipment such as mixing tanks, reaction vessels, and storage tanks, especially in the powder manufacturing industry, which involves various equipment for storing liquid slurries. The bottom valves of this equipment are highly prone to clogging. A bottom valve typically consists of a valve body, valve cover, valve disc, sealing ring, and gasket, and has a check valve function, ensuring that liquid flows in only one direction in the pipeline, effectively preventing backflow. However, unclogging a bottom valve, while seemingly simple, is actually time-consuming and labor-intensive, resulting in a significant waste of production labor and reduced production efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a device for unblocking bottom valves and cleaning pipes with pressurized gas. This device unblocks the bottom valves and pipes without causing pollution to the bottom valves and pipes, and saves manpower.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dredging bottom valve cleaning pipeline pressurization device, including a tank, a bottom valve, a discharge pipe, and a guide pipe; the bottom of the tank is provided with a bottom valve, the bottom of the bottom valve is connected to the discharge pipe, and the bottom side wall of the discharge pipe is connected to the guide pipe; the middle side wall of the discharge pipe is connected to one end of an air inlet pipe, the other end of the air inlet pipe is connected to an air source, and an air valve is provided on the air inlet pipe; a rotating shaft is provided inside the discharge pipe at the connection with the air inlet pipe, the two ends of the rotating shaft are connected to the shaft seats on the inner wall of the discharge pipe, and baffles are connected to both sides of the rotating shaft; a motor is installed on the outer wall of the discharge pipe, and the output shaft of the motor is connected to the rotating shaft inside the discharge pipe; the motor can drive the rotating shaft to rotate precisely, so that the baffles can remain vertical and tilt left and right inside the discharge pipe.

[0005] The air valve is an electrically controlled air valve. Opening the air valve allows high-pressure gas to be injected into the lower feed pipe for unblocking and cleaning.

[0006] The bottom end of the feeding pipe is provided with a drain port, and a sealing plug is movably connected to the drain port; during normal feeding, the sealing plug is tightly installed at the drain port; when cleaning the inner wall of the feeding pipe, the sealing plug can be opened so that the cleaned material can be discharged from the drain port.

[0007] The discharge pipe is a square pipe, and the baffle is a square plate. The size of the baffle is adapted to the size of the discharge pipe. When the baffle is tilted, it can completely fit and contact the inner wall of the discharge pipe, thereby ensuring the cleaning effect.

[0008] The beneficial effects of this utility model are: the pressurized device for unblocking bottom valves and cleaning pipes has a rotatable baffle installed inside the discharge pipe. When the baffle is in a vertical state inside the discharge pipe, it does not affect the normal discharge of materials. When the baffle is in a tilted state to the left or right inside the discharge pipe, high-pressure gas is injected into the air inlet pipe to purge and clean the bottom valve and the discharge pipe. Unblocking and cleaning by pressurized gas will not contaminate the bottom valve and the pipe, saving manpower. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] Reference Figure 1-4This embodiment provides a pressurized device for unblocking bottom valves and cleaning pipes, including a tank 1, a bottom valve 2, a discharge pipe 3, and a guide pipe 4; the bottom of the tank 1 is provided with a bottom valve 2, the bottom of the bottom valve 2 is connected to the discharge pipe 3, and the bottom side wall of the discharge pipe 3 is connected to the guide pipe 4; the middle right side wall of the discharge pipe 3 is connected to one end of an air inlet pipe 5, the other end of the air inlet pipe 5 is connected to an air source, and an air valve 6 is provided on the air inlet pipe 5; a rotating shaft 7 is provided inside the discharge pipe 3 at the connection with the air inlet pipe 5, the two ends of the rotating shaft 7 are connected to the bearing seats on the inner wall of the discharge pipe 3, and baffles 8 are connected to both sides of the rotating shaft 7; a motor 9 is installed on the outer wall of the discharge pipe 3, and the output shaft of the motor 9 is connected to the rotating shaft 7 inside the discharge pipe 3.

[0017] In this embodiment, the air valve 6 is preferably an electrically controlled air valve. Normally, the air valve 6 is in the closed state when feeding material. Opening the air valve 6 can inject high-pressure gas into the feed pipe 3 for unblocking and cleaning.

[0018] In this embodiment, in order to facilitate the discharge of the cleaned material, the bottom end of the feed pipe 3 is provided with a drain port, and a sealing plug 10 is movably connected to the drain port; during normal feeding, the sealing plug 10 is tightly installed at the drain port; when cleaning the inner wall of the feed pipe, the sealing plug 10 can be opened so that the cleaned material can be discharged from the drain port.

[0019] In this embodiment, in order to ensure the sealing performance when the baffle 8 contacts the discharge pipe 3, the discharge pipe 3 is preferably a square pipe and the baffle 8 is preferably a square plate. The shape and size of the baffle 8 are adapted to the internal size of the discharge pipe 3. When the baffle 8 is tilted, it can completely fit and contact the inner wall of the discharge pipe 3, thereby ensuring the effect of unblocking and cleaning.

[0020] Reference Figure 2 , Figure 2 The arrows indicate the direction of material descent. During normal feeding, the baffle 8 is in a vertical position and will not affect the material descent. The material falls to the bottom of the feeding pipe 3 and then enters the guide pipe 4 for transfer.

[0021] Reference Figure 3 , Figure 3 The arrows in the diagram indicate the direction of high-pressure gas flow. When unblocking the bottom valve 2, the angle of the baffle 8 is adjusted by the motor 9 so that the top of the baffle 8 contacts the inner wall on the left side of the feed pipe 3 and the bottom of the baffle 8 contacts the inner wall on the right side of the feed pipe 3. The gas valve 6 is then opened, and the high-pressure gas enters the bottom valve 2 upwards to purge it. After unblocking the bottom valve 2, the gas enters the kettle cover 1, thus unblocking the bottom valve 2.

[0022] Reference Figure 4 , Figure 4The arrows in the diagram indicate the direction of high-pressure gas flow. After the bottom valve 2 is cleared, the angle of the baffle 8 is adjusted by the motor 9 so that the top of the baffle 8 contacts the inner wall on the right side of the discharge pipe 3 and the bottom of the baffle 8 contacts the inner wall on the left side of the discharge pipe 3. The air valve 6 is opened, and the high-pressure gas enters the discharge pipe 3 downwards for purging. At the same time, the sealing plug 10 is opened, and the purged material, water, etc. are discharged from the drain outlet.
