Description

Technical Field

[0001] This utility model relates to the field of engineering equipment, specifically to a portable pulping machine. Background Technology

[0002] In the blast furnace ironmaking process, the hot blast stove is one of the key pieces of equipment. The operating temperature in localized areas such as the ignition holes is extremely high, often exceeding 300°C. To prevent serious accidents such as burn-through caused by prolonged overheating of the furnace shell, it is necessary to periodically apply refractory slurry to these high-temperature areas to form a protective layer and extend the equipment's lifespan.

[0003] Currently, the industry generally uses traditional dedicated pulping machines for this operation. This equipment has several significant drawbacks: First, the equipment itself is very bulky, making movement and installation extremely inconvenient. Long pipelines need to be laid during operation, making preparation work cumbersome. Operating one pulping machine typically requires six to seven people working together, resulting in high labor costs and organizational difficulties. Furthermore, traditional pulping machines operate at excessively high pressures (usually 2-3 MPa). Improper operation can easily damage the refractory masonry inside the hot blast stove, posing a risk of secondary damage. Finally, this method also suffers from significant material waste. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a portable pulping machine that can effectively solve the problems mentioned in the background art.

[0005] The present invention adopts the following technical solution: a portable pulping machine, comprising a pressure tank, a pulp outlet hose, and an air source hose. The pressure tank is provided with a pulp outlet port at the top and an air inlet port at the bottom. One end of the pulp outlet hose is connected to the pulp outlet port at the top of the pressure tank, and the other end is provided with a reducing connector and a pressure relief valve for connecting to the pulp receiving equipment. One end of the air source hose is connected to the air inlet port at the bottom of the pressure tank, and the other end is provided with a third connector for connecting to an external air source.

[0006] The slurry outlet hose and the pressure tank are connected by a first connector threaded connection, and the air source hose and the pressure tank are connected by a second connector threaded connection.

[0007] The discharge hose is threadedly connected to the receiving equipment via a reducing connector.

[0008] The working pressure of the pressure tank is ≤0.5MPa.

[0009] The pressure tank is made of stainless steel or pressure-resistant engineering plastic, and the slurry outlet hose and air source hose are made of steel wire reinforced pressure-resistant rubber hose or hydraulic resin hose.

[0010] The pulping machine is a portable structure that can be carried by hand or on your back.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This device adopts a compact design with integrated pressure tank, slurry outlet hose and air source hose, uses all existing spare parts, can be reused after cleaning, saves labor, and only requires 1-2 people to operate. By controlling the working pressure to a low range of ≤0.5MPa, the safety of operation and protection of the slurry receiving equipment are improved. The components are connected by threaded joints, which makes assembly and disassembly simple, has good sealing performance and reliable connection, and ensures the sealing performance during operation, reducing the ineffective loss of materials.
