Description

Technical Field

[0001] This utility model relates to the field of positive pressure conveying technology, specifically a positive pressure conveying device with self-cleaning function. Background Technology

[0002] Positive pressure conveying is a material conveying method that uses compressed air as a power source. Its working principle involves a fan at the front end of the conveying system introducing compressed air into the pipeline. The pressure difference between the beginning and end of the pipeline causes the air to flow within the pipeline, thus moving the material. Positive pressure conveying devices are core material conveying equipment in fields such as chemical engineering, building materials, grain processing, and pharmaceutical production. They are mainly used for the efficient transfer of powdered and granular materials (such as chemical raw material powders, cement granules, grain granules, and pharmaceutical intermediate powders). However, current positive pressure conveying devices lack self-cleaning capabilities, requiring the pipeline to be disassembled and cleaned after use, which is very inconvenient. Therefore, we propose a positive pressure conveying device with a self-cleaning function. Utility Model Content

[0003] The purpose of this invention is to provide a positive pressure conveying device with a self-cleaning function, which solves the problem that current positive pressure conveying devices do not have a self-cleaning function, resulting in the need to disassemble the pipes for cleaning after use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positive pressure conveying device with self-cleaning function, comprising a base plate, a storage box fixedly connected to the right end of the top of the base plate via a bracket, a conveying box fixedly connected to the middle end of the top of the base plate via a bracket, a Roots blower fixedly connected to the rear left end of the top of the base plate, a conveying pipe provided on the left side of the storage box, the air outlet of the Roots blower fixedly connected to the conveying pipe via a pipe, a guide pipe fixedly connected to the bottom of the conveying box, the bottom of the guide pipe fixedly connected to the conveying pipe, a high-pressure blower fixedly connected to the left end of the top of the base plate, the air outlet of the high-pressure blower fixedly connected to the conveying pipe, a spiral air outlet provided at the air outlet of the high-pressure blower, and a spiral guide extension plate provided on the inner wall of the elbow of the conveying pipe.

[0005] Preferably, the feed pipe includes a stainless steel layer, a nano-zirconia ceramic liner layer, and a honeycomb micro-concave structure layer, wherein the stainless steel layer is located outside the nano-zirconia ceramic liner layer, and the nano-zirconia ceramic liner layer is located outside the honeycomb micro-concave structure layer.

[0006] Preferably, the outlet of the high-pressure blower is provided with a third valve, and the outlet of the Roots blower is provided with a first valve.

[0007] Preferably, the inner cavity of the feed pipe is provided with a second valve, the top of the storage box is provided with a bag filter, and the spiral guide extension plate has an axial angle of 30 degrees with the feed pipe.

[0008] Preferably, the bottom plate has fixing blocks fixedly connected to both the front and rear ends on the left and right sides, and bolts are provided on the fixing blocks.

[0009] Preferably, a toolbox is fixedly connected to the top of the base plate, and the inner cavity of the toolbox is provided with a partition.

[0010] Preferably, a PLC controller is fixedly connected to the top of the base plate, and the output terminal of the PLC controller is electrically connected to the input terminal of the high-pressure blower and the Roots blower.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model's Roots blower provides a stable positive pressure airflow, achieving efficient material conveying through the conveying pipe. The guide pipe at the bottom of the conveying box, in conjunction with the second valve, can precisely control the material feed rate, preventing overfeeding and blockage. The high-pressure blower at the top left of the base plate blows out spiral airflow through the spiral outlet, which, together with the spiral guide extension plate on the inner wall of the conveying pipe bend, forms a rotating airflow that can quickly flush away residual material on the inner wall of the pipe and at the bend, completing cleaning without disassembling the pipe. The bag filter at the top of the storage box can filter dust generated during the conveying process, preventing dust emissions from polluting the environment and ensuring workshop air quality and worker health. The first valve, second valve, and third valve control the on / off of the Roots blower, guide pipe, and high-pressure blower, respectively, enabling rapid switching between conveying and cleaning modes, and flexible operation.

[0012] 2. The material conveying pipe of this utility model adopts a three-layer composite structure. The outer stainless steel layer ensures the structural strength, the middle nano-zirconia ceramic inner lining layer has excellent wear resistance and corrosion resistance, and can resist the wear of hard materials and the erosion of corrosive materials. The inner honeycomb micro-concave structure layer reduces the contact area between the material and the inner wall of the pipe, and reduces the probability of adhesion. Attached Figure Description
