Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the present invention comprises a hollow silo 6, a storage hopper 13 and a silo 10, and the silo 6 and the storage silo 10 communicate with each other through a transport pipe 8 provided with a first rotary valve 4, and the storage hopper 13 is connected to the hopper 10. The bins 10 are communicated through the second rotary valve 12, and there is a feeding pipe 20 connected to the packaging bag under the bin 10, and a gas pipe 2 connected to the atmosphere is connected to the transportation pipe 8, and the gas pipe 2 is located behind the first rotary valve 4 . An air filter 1 is also connected to the air pipe 2 . A dust collector 14 is connected between the vacuum generator 16 and the storage material. The feeding pipe 20 is also connected with a butterfly valve 18 .

[0014] Principle of the present invention is as follows:

Abstract

The invention discloses a pneumatic conveying device, comprising a hollow silo, a storage hopper and a stock bin, wherein the silo and the stock bin are communicated by a conveying pipe provided with a first rotary valve; the storage hopper and the stock bin are communicated by a second rotary valve; a feeding pipe which is communicated with a packaging bag is also arranged below the stock bin. The pneumatic conveying device is characterized in that an air pipe which is communicated with the atmosphere is also connected with the conveying pipe; the air pipe is located behind the first rotary valve. The pneumatic conveying device with the structure is low in conveying speed; the wear of the conveying pipe is reduced; the conveying pipe is prevented from being blocked; electrostatic charges can be effectively reduced; the explosion of materials is avoided.

Description

technical field [0001] The invention relates to a material conveying device, which belongs to the field of packaging and transportation. Background technique [0002] The transportation of products before packaging is an important process of product production. Many industries such as chemical industry, petroleum, grain, food, and medicine are involved in product transportation, and according to the different forms of products, there are also many types of packaging involved. With the progress of mechanization, the current packaging and transportation technology has been scaled up. However, there are also some problems in the prior art, especially when transporting granular and powdery materials over long distances, there are often problems such as material accumulation, wear and tear of conveying pipes, and explosion of powdery materials under the influence of static charges. Contents of the invention [0003] The technical problem to be solved by the present invention i...
