Description

Technical Field

[0001] The utility model belongs to the technical field of air locks, and particularly relates to a cleaning type air lock. Background Art

[0002] An air lock is a device widely used in industrial equipment to control the flow of materials. It is commonly found in pneumatic conveying systems and powder and granular material processing equipment. It is mainly responsible for preventing material backflow when the system stops working, and regulating and releasing materials when working. An air lock usually includes a rotating impeller with blades and a corresponding sealing structure to ensure that the material can only flow in a specified direction. A cleaning-type air lock is designed on the basis of a traditional air lock to be easy to disassemble and clean, so that users can regularly perform internal cleaning and maintenance to remove accumulated dust, particulate matter and other debris, maintain the working efficiency of the air lock and extend its service life. Existing cleaning-type air locks use external tools to remove bolts to disassemble the air lock for cleaning, which makes it more troublesome for personnel to disassemble.

[0003] For example, the utility model with announcement number CN207090527U discloses a cleaning type air lock, in which a threaded side cover is hinged to the outer shell at the side through four joint pages, and two upper and lower locking grooves are respectively processed on both sides of the threaded side cover, and four fastening bolts are hinged to the front side of the outer shell at the corresponding positions of the locking grooves, and the fastening bolts are respectively threadedly assembled with knurled nuts. In the present patent scheme, the threaded side cover is disassembled by disassembling the fastening bolts, thereby realizing the cleaning of the inside of the air lock. The removal of the bolts requires tools and time, and the operation is relatively complicated, especially when operating in a small space. If the operation is improper or the force is too great, it may cause damage to the bolts or other components, increasing the safety risk and the maintenance cost, especially when the air locks are disassembled and cleaned in batches, which makes the cleaning workload large.

The output shaft rotates to drive the rectangular frame on the rotating column to rotate, so that the rectangular block inside it drives the impeller to rotate, which can quickly release the material and discharge it from the discharge pipe.

[0010] Secondly, by pulling the pull plate, the rectangular plate on the frame plate moves upward, driving the locking column at the lower end of the rectangular plate to leave the interior of the locking hole. At this time, the spring is in a compressed state, and then the sliding cover plate is pulled out to the left through the handle, driving the impeller to leave the interior of the box.

The quick disassembly and assembly mechanism can quickly realize the disassembly and installation of the air lock to realize the cleaning of the interior. The operation is relatively simple and does not require the use of tools, which reduces the tediousness of the disassembly process. Especially when the air locks are disassembled and cleaned in batches, the cleaning workload is relatively small.

[0011] Thirdly, when a person pulls the pull plate, the protective protrusion can enhance the friction between the person's hand and the pull plate, thus preventing the person's hand from slipping.

[0012] Fourthly, the sealing strip can increase the sealing performance between the sliding cover plate and the left end of the box body, thereby preventing dust from entering the interior of the air lock. BRIEF DESCRIPTION OF THE DRAWINGS
