Sponge blowing device and system for cleaning inner wall of pipe

Abstract

The invention discloses a sponge blowing device and system for cleaning the inner wall of a pipe. The sponge blowing device comprises at least two blowing mechanism assemblies, and each blowing mechanism assembly comprises a blowing body, a blowing nozzle, a negative pressure mechanism and a gas conveying mechanism, wherein the blowing body is provided with a blowing cavity and a first cleaning block inlet communicating with a blowing cavity; the blowing nozzle is connected with the blowing body, and a negative pressure opening is formed in the blowing nozzle; the negative pressure mechanism is connected with the negative pressure opening so as to generate negative pressure for conveying a cleaning block at the first cleaning block inlet to the blowing nozzle; and the gas conveying mechanism comprises a push rod, a gas channel is formed in the push rod, a gas outlet is formed in one end of the push rod, the push rod can move in the axis direction of the push rod, so that the push rod entering the blowing cavity can move to the other end of the blowing cavity to be in sealed connection with the blowing nozzle, and compressed gas conveyed by the gas channel is used for blowing the cleaning block to penetrate through a to-be-cleaned pipeline opposite to the blowing nozzle.

Description

technical field [0001] The invention belongs to the technical field of cleaning devices, and in particular relates to a sponge blowing device and system for cleaning the inner wall of pipes. Background technique [0002] In the process of metal material pipe processing, when the pipe is cold rolled, it is often necessary to pour lubricating liquid into the inner wall of the pipe. After high-speed rolling and deformation, oil stains and metal chips will be formed on the inner wall of the pipe, which needs to be degreased or pickled. deal with. After the treatment, there will be a certain amount of oily wastewater, metal shavings, and acid-containing wastewater on the inner wall of the pipe, which does not meet the cleaning requirements. In order to ensure the cleanliness of the inner surface of the pipe, the sponge block is generally inserted into one end of the pipe by manual means, and then the air is used to clean it. Blow out and reciprocate several times until the inner...

Problems solved by technology

After the treatment, there will be a certain amount of oily wastewater, metal shavings, and acid-containing wastewater on the inner wall of the pipe, which does not meet the cleaning requirements. In order to ensure the cleanliness of the inner surface of the pipe, the sponge block is generally inserted into one end of the pipe by manual means, and then the air is used to clean it. Blow out and reciprocate several times until the inner wall of the pipe is blown clean

And for small-sized pipes (outer diameter ≤ Φ10mm), when manually processing, the sponge block is screwed into the pipe by hand. If you don’t pay attention, your fingers are easily scratched by the end surface of the pipe, so the production efficiency is low, time-consuming and labor-intensive. , and the production process is not standardized
