Description

Technical Field

[0001] This utility model relates to the field of reactor technology, specifically to a dustproof feeding port for a reactor. Background Technology A reactor is a device that reacts various raw materials of different phases under specific conditions, including time, temperature, pressure, and flow rate, to produce corresponding output materials. Almost any chemical reaction process requires a reactor, which is widely used in fields such as energy, environmental engineering, biotechnology and pharmaceuticals, materials science, metallurgy and mining, and aerospace.

[0002] Currently, to improve reactor conversion rates, the solution is to control material flow, mixing, heat and mass transfer, maintaining the most efficient process conditions, thereby improving the purity and yield of the output material. Furthermore, for solid raw materials, powder form is generally used to increase specific surface area, shorten internal diffusion distance, and accelerate reaction speed. Conventional methods for feeding powdered solid raw materials into the reactor include: manual batch feeding; mechanical feeding using equipment such as screw feeders, rotary valve feeders, and loss-in-weight feeders; pneumatic conveying; and premixing the powdered material with a reaction solvent or water before slurry feeding.

[0003] However, when powdered solid raw materials are introduced into the reactor, the powdered materials are prone to generating dust, which poses problems such as environmental damage, equipment damage, and harm to personnel health. Utility Model Content

[0004] In order to solve the technical problems existing in the background art, the present invention provides a dustproof feeding port for a reactor, which can suppress the outward diffusion of dust when powdered solid raw materials are fed into the reactor, and is more in line with the requirements of environmental protection and safety.

[0005] The technical solution adopted by this utility model is: A dustproof feeding port for a reactor includes: A variable-diameter cylinder with a smaller bottom and a larger top, wherein the lower end of the variable-diameter cylinder is provided with a...

[0006] An extension cylinder is sealed at the upper end of the variable diameter cylinder. An exhaust port is connected to the side wall of the extension cylinder. A hinge shaft and a baffle are fixedly installed on the outer wall of the extension cylinder. Inner liner cylinders are inserted at intervals inside the extension cylinder. A sealing flange is installed at the upper end of the extension cylinder.

[0007] The sealing cover on the closed flange is provided with a blind plate, and a rotating shaft is rotatably provided at the upper end of the blind plate. Rotating arms are respectively rotatably provided at both ends of the rotating shaft, and the ends of the rotating arms are sleeved on the hinge shaft.

[0008] Furthermore, the variable diameter cylinder is configured as concentric or elbow-shaped to allow the extension cylinder to be positioned with its axis in a vertical direction.

[0009] Furthermore, the extended cylindrical body is configured to be cylindrical.

[0010] Furthermore, the connecting flange is welded to the small head at the lower end of the variable diameter cylinder.

[0011] The closed flange is welded to the upper end of the variable diameter cylinder.

[0012] The lower end of the sealing flange is welded to the upper end of the connecting flange.

[0013] Furthermore, the exhaust port is connected to the feeding equipment via an induced draft fan.

[0014] Furthermore, a frustum-shaped connecting pipe is provided at the upper end of the inner lining cylinder, with the large end of the connecting pipe sealed and welded to the inner wall of the extension cylinder, and the small end of the connecting pipe sealed and welded to the upper end of the inner lining cylinder.

[0015] Furthermore, the stirring section is located away from the reactor: The hinge shafts are symmetrically arranged on both sides of the extension cylinder, and the axis of the hinge shafts is spatially perpendicular to the axis of the extension cylinder. The exhaust port is welded to the outer wall of the extension cylinder outside the inner liner cylinder, and the axis of the exhaust port is perpendicular to the plane of the axis of the extension cylinder. The lugs are welded onto the outer wall of the extension cylinder.

[0016] Furthermore, a rotating shaft seat for rotatably inserting a rotating shaft is welded to the upper end of the blind plate, and the axis of the rotating shaft is parallel to the axis of the hinge shaft and is arranged in the horizontal direction.

[0017] Furthermore, the end of the rotating arm is provided with a waist-shaped hole for the rotating sleeve hinge shaft.

[0018] The beneficial effects of the dustproof feeding port of the reactor of this utility model are as follows: 1. The variable diameter cylinder increases the diameter of the feeding port, making it easier for the feeding equipment to extend into the reactor; 2. A negative pressure is generated inside the reactor through the exhaust vent, causing dust to be drawn into the reactor through the gap between the feeding equipment and the extension cylinder; the extension cylinder is divided into inner and outer layers by the inner lining cylinder. The inner layer ensures normal feeding, while the outer layer ensures that the exhaust vent keeps the reactor under negative pressure. Attached Figure Description
