Description

Technical Field

[0001] This utility model relates to the technical field of bag expanders for inorganic powders, specifically to a flexible ring-type bag expander for inorganic powders. Background Technology

[0002] Currently, the bag clamping and pressing devices in the inorganic powder industry tighten the bags from the side, leaving gaps on both sides of the belt after clamping, which cannot completely seal the bag. During the feeding process, the positive pressure inside the bag causes material to overflow from the un-clamped gaps, generating dust. Furthermore, the bag opening needs to be held down by hand during clamping until it is fully tightened, posing a safety hazard. Therefore, a flexible ring-type bag expander for inorganic powders is proposed. This expander uses a flexible expansion structure to ensure the bag opening fits snugly against the outer wall of the discharge structure, preventing dust generation during discharge. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a flexible ring-type bag expander for inorganic powders. The flexible expansion structure allows the bag opening to fit snugly against the outer wall of the discharge structure to avoid dust generation during discharge.

[0004] The technical solution adopted by this utility model to solve its technical problem is a flexible ring-type bag expander for inorganic powder, including a pneumatic butterfly valve, a material pipe, a bearing ring, a support ring and a bag body. Small electric push rods and small air pumps are respectively installed on both sides of the bearing ring through brackets and bolts.

[0005] An air bladder is adhered to the inner wall of the support ring, and an air nozzle is inserted through an opening on one side of the support ring. An exhaust pipe is inserted through an opening on another side of the support ring away from the air nozzle.

[0006] By adopting the above technical solution, a small electric push rod and a small air pump are fixed by a bearing ring, and the air bag is glued to the outside of the material tube by the support ring.

[0007] Place the bag opening around the material pipe and inside the air bladder. Turn on the small air pump to inflate the air bladder through the air delivery hose and air nozzle to ensure that the bag opening is tightly against the outside of the material pipe to avoid dust generation during material discharge. After bagging, turn on the solenoid valve to discharge the gas in the air bladder through the exhaust pipe so that the bag can be detached.

[0008] Meanwhile, a small electric push rod can be used to drive the lifting frame, which in turn drives the support ring and airbag to be raised and lowered around the material tube, so as to make adjustments according to the different depths of the bag, making the adjustment convenient.

[0009] Specifically, a connecting flange A is provided on the outer periphery of the bottom end of the pneumatic butterfly valve, and a connecting flange B is provided on the outer periphery of the top end of the material pipe. The pneumatic butterfly valve and the material pipe are connected and fixed through connecting flange A and connecting flange B.

[0010] By adopting the above technical solution, connecting flange A and connecting flange B are used to facilitate the connection and fixation of the pneumatic butterfly valve and the material pipe.

[0011] Specifically, a bearing ring is fixed through the top of the material tube, and a support ring is located at the bottom of the bearing ring on the outer periphery of the material tube.

[0012] By adopting the above technical solution, a small electric push rod and a small air pump are fixed by using a bearing ring.

[0013] Specifically, a lifting frame is installed on the other side of the support ring, and the drive end of the small electric push rod is connected to the lifting frame.

[0014] By adopting the above technical solution, the support ring is used to bond the airbag to the outside of the material tube.

[0015] Specifically, one end of the air nozzle and the exhaust pipe are both connected to the airbag, and a flexible air supply hose is connected between the small air pump and the air nozzle. The air outlet of the small air pump is connected to the flexible air supply hose.

[0016] By adopting the above technical solution, a small air pump is turned on to inflate the air bag through the air delivery hose and air nozzle, so as to keep the bag opening tightly attached to the outside of the material pipe and avoid dust problems during material discharge.

[0017] Specifically, the exhaust pipe opening is connected to a solenoid valve, and the opening of the bag body is located between the outer periphery of the material pipe and the air bladder.

[0018] By adopting the above technical solution, after the bag is filled, the solenoid valve is opened to release the gas in the airbag through the exhaust pipe, so that the bag can be detached.

[0019] The beneficial effects of this utility model are:

[0020] (1) The flexible ring-type bag expander for inorganic powder described in this utility model is to put the bag opening around the material pipe and inside the air bladder. A small air pump is turned on to inflate the air bladder through the air delivery hose and air nozzle so as to make the bag opening close to the outside of the material pipe to avoid dust problems when discharging. After the bag is filled, the solenoid valve is turned on to discharge the gas in the air bladder through the exhaust pipe so that the bag can be removed.

[0021] (2) The flexible ring-type bag expander for inorganic powder described in this utility model uses a small electric push rod to drive the lifting frame to move the support ring and air bladder around the material tube for adjustment, so as to make adjustments according to different bag depths and making adjustment convenient.
