[0006] In use, the positioning tube is inserted into the receiving port of the reaction kettle, the positioning tube is attached to the inner wall of the receiving port, and the positioning ring on the outer wall of the positioning tube is blocked on the receiving port to position the positioning tube and prevent it from falling into the reaction kettle.The solid material packaging bag is placed on the grid plate through the opening of the dust shielding bag, the hanging rope on the solid material packaging bag is connected to the lifting hook of the electric hoist, and the dust shielding bag is closed.The electric hoist lifts the solid material packaging bag, the solid material packaging bag rises and separates from the grid plate, and the solid material in the packaging bag falls into the receiving port from the opening of the packaging bag.During the falling process of the solid material, the dust is blocked by the sealing ring and falls back, and the dust shielding bag further blocks the dust, reducing the dust dispersion during solid feeding and the impact on the health of operators.The open solid material packaging bag is placed on the grid plate and lifted by the electric hoist, realizing portable operation of solid feeding.

[0007] The material of the dust shielding bag is anti-static material to avoid the occurrence of fire caused by static electricity.

[0008] The dust shielding bag fixing ring comprises a clamping ring, a push rod and a supporting rod are arranged on the inner wall of the clamping ring, the push rod is rotationally connected to the clamping ring through a push rod pivot, the supporting rod is rotationally connected to the clamping ring through a supporting rod pivot, the supporting rod is rotationally connected to the push rod through a clamping ring pivot, and a clamping ring gap is arranged between the push rod pivot and the supporting rod pivot. The push rod rotates around the push rod pivot to move the push rod towards or away from the supporting rod pivot; when the push rod moves away from the supporting rod pivot, the push rod pivot and the supporting rod pivot move towards each other (the clamping ring gap is reduced), the diameter of the clamping ring is reduced, and thus the dust shielding bag fixing ring can be moved into or out of the fixing ring limiting groove; when the push rod moves towards the supporting rod pivot, the push rod pivot and the supporting rod pivot move away from each other (the clamping ring gap is increased), the diameter of the clamping ring is increased, and thus the dust shielding bag fixing ring can be clamped into the fixing ring limiting groove to fix and connect the solid material packaging bag in the fixing ring limiting groove.

[0009] When the dust shielding bag fixing ring is fixed and connected in the fixing ring limiting groove, the included angle between the push rod and the shaft rod is greater than 190 degrees, and the included angle is an included angle towards the clamping ring gap. The included angle between the push rod and the shaft rod is greater than 190 degrees, and the push rod can be automatically locked.

[0010] The head of the feeding pipe is a horn pipe, and the grid plate is arranged in the horn pipe. The horn pipe can increase the inner diameter of the feeding pipe, and the solid material packaging bag can be conveniently put into the feeding pipe.

[0011] The positioning ring is provided with a bolt clamping groove, and the bolt at the material receiving port of the reaction kettle is clamped into the bolt clamping groove, so that the positioning ring is tightly connected at the material receiving port.

[0012] The detachable dust shielding bag fixing ring can easily disassemble and assemble the dust shielding bag, so that the dust shielding bag can be replaced.

[0013] The utility model can reduce the dust emission during feeding, reduce the influence of dust on the health of operators, and also reduce the workload of operators. BRIEF DESCRIPTION OF DRAWINGS
