Problems solved by technology

[0003] Bucket elevators are widely used to transport various materials, and a large amount of dust will be generated during the transportation process. When the dust reaches a certain concentration in the outside world, it is easy to be heated and catch fire, causing great harm and poor sealing. Powder leakage, air leakage and other problems, which are prone to spontaneous combustion and explosion, seriously affect safe production, and seriously pollute the environment

Embodiment 1

[0033] Embodiment 1: During the lifting and transportation of materials, low-pressure nitrogen is filled into the nitrogen interface in the bottom shell 2, so that the nitrogen pressure in the shell is higher than the external air pressure, thereby effectively preventing external air from entering the bottom Inside the shell 2, at the same time, low-pressure nitrogen is filled into the nitrogen interface of the intermediate shell 3, so that the material inside the conveying channel is isolated from the air, and the nitrogen acts as a protective gas, thus effectively avoiding possible powder and air leakage , which also ensures the safety of the material during the conveying process, and by filling the nitrogen interface of the head shell 4 with low-pressure nitrogen, the nitrogen is filled in the head shell 4, thereby isolating the outside air from entering from the discharge port into the head housing 4.

Embodiment 2

[0035]Embodiment 2: During the lifting and transportation of materials, a vacuum generating device is installed on one side of the casing 1. Since a sealing layer 6 is provided between the sealing cover plate 5 and the casing 1, the sealing layer 6 is filled in the Between the sealing cover plate 5 and the shell 1, the sealing layer 6 is a high-strength graphite composite plate gasket, the joint between the intermediate shell 3 and the bottom shell 2 is sealed and connected with the sealing cover plate 5 and the sealing layer 6, the intermediate shell 3 and the The junction of the head shell 4 is sealed with a sealing cover plate 5 and a sealing layer 6. The inside of the shell is a sealed vacuum space, and the material can be transported in a vacuum state, thereby effectively avoiding powder leakage and air leakage, thereby ensuring The safety of materials during transportation.

Embodiment 3

[0037] Embodiment 3: In the process of material lifting and transportation, the sealing cover 5 used is a half-enclosed or fully-enclosing folding plate, only a small amount of screws are required to be fixed on the housing 1, and the joint of the sealing cover 5 A sealing layer is filled between the place and the housing 1, so that the sealing performance between the sealing cover plate 5 and the housing 1 is better, which not only reduces the use of screws, but also further enhances the airtightness of the housing 1.

[0038] The material is filled into the tail shell at the hopper, and the material is vertically conveyed to a high place by the hopper belt moving up and down. During the working process, the joint between the middle shell 3 and the head shell 4 is sealed and installed with a sealing cover plate 5 and a sealing layer 6, and the outside of the joint between the middle shell 3 and the head shell 4 is a 90-degree rounded structure , the inner side of the joint be...

Abstract

The invention discloses a bucket type airtight elevator which comprises a shell. The shell includes a bottom shell, a middle shell and a head shell. The shell is fixedly arranged on the ground throughfoundation bolts distributed on the periphery of the bottom shell. Sealing cover plates are arranged on the outer side of the shell and are fixedly installed on the shell through screws. The two endsof the sealing cover plates are of 90-degree rounded-corner arc structures. The middles of the sealing cover plates are in a horizontal state. The sealing cover plates are fixedly connected through abolt, a sealing layer is arranged among the sealing plates and the shell, and the part among the sealing cover plates and the shell is filled with the sealing layer. By means of the bucket type airtight elevator, a sealing structure is adopted, the sealing performance of materials in the conveying process is ensured, contact between the materials and air in the elevator is effectively prevented,powder leakage and gas leakage are avoided, safety of the material in the conveying process is ensured, and it can be ensured that the materials safely and reliably run for a long time in specified environment conditions.

Description

technical field [0001] The invention relates to the field of airtight elevators, in particular to a bucket-type airtight elevator. Background technique [0002] As a vertical conveying equipment, the bucket elevator has the advantages of large lifting height, stable lifting and small footprint. It is widely used in grain, feed and seed processing enterprises. It uses the connection between the hopper belt and the drive shaft of the head Friction torque is used to lift and transport materials. [0003] Bucket elevators are widely used to transport various materials, and a large amount of dust will be generated during the transportation process. When the dust reaches a certain concentration in the outside world, it is easy to be heated and caught fire, causing great harm and poor sealing. Powder leakage, air leakage and other problems, which are prone to spontaneous combustion and explosion, seriously affect safe production, and seriously pollute the environment. Contents o...
