Description

Technical Field

[0001] This utility model is an anti-clogging feeding device for potassium carbonate conveying pipelines. Background Technology

[0002] Potassium carbonate (chemical formula: K₂CO₃), as an important inorganic chemical raw material, is widely used in glass manufacturing, fertilizer production, food processing, and the pharmaceutical industry. Its physical form is usually a white crystalline powder with a density of approximately 2.428 g / cm³ and a melting point of 891℃. Potassium carbonate is readily soluble in water, and its aqueous solution is strongly alkaline, but it is insoluble in organic solvents such as ethanol, acetone, and ether. Notably, potassium carbonate has strong hygroscopic properties; when exposed to air, it readily absorbs moisture and carbon dioxide, gradually converting into potassium bicarbonate (KHCO₃). This characteristic is particularly prominent during its storage and transportation, becoming a key factor affecting the flowability of the material.

[0003] In modern chemical production, the transport of potassium carbonate largely relies on automated systems. Common mechanical conveying devices include conveyor belts, screw feeders, pneumatic conveying systems, and robotic arms. These devices are connected to reactors, silos, or packaging systems via pipelines to achieve continuous or intermittent material transport. However, due to the hygroscopic and agglomerating properties of potassium carbonate, it is prone to forming solidified lumps during pipeline transport due to humidity, temperature changes, or compaction, leading to partial or complete blockages in the pipelines. This blockage not only affects production efficiency and the accuracy of material metering but can also cause a series of problems such as system downtime, increased energy consumption, and equipment wear.

[0004] Currently, the most common approach to dealing with pipe blockages is still manual intervention. On-site operators need to conduct regular inspections and restore pipe flow through methods such as tapping, vibration, or disassembly. While this method is simple and direct, it has the following significant drawbacks: First, it is labor-intensive, especially in large production systems where pipes are widely distributed, making it difficult to cover all critical areas manually. Second, the response is not timely, as blockages often occur during system operation, making real-time monitoring and handling difficult through manual inspections. Third, the tapping force and frequency are difficult to standardize, potentially leading to pipe damage or uneven results.

[0005] Although some anti-clogging devices exist in existing technologies, such as mechanical vibrators and pneumatic arch-breaking devices, most of these devices are complex in structure, inconvenient to install, or unable to adapt to the characteristics of potassium carbonate materials, especially under conditions of large humidity fluctuations and easy adhesion. In addition, most devices lack intelligent control functions and cannot automatically adjust operating parameters according to the material state and conveying conditions, still requiring manual operation and adjustment based on experience.

[0006] Therefore, for the conveying process of materials such as potassium carbonate that are easily hygroscopic and prone to caking, there is an urgent need to develop a new type of anti-clogging feeding device that is simple in structure, flexible in installation, automatically controllable, and highly adaptable, so as to effectively prevent and promptly deal with pipeline blockage problems, and improve the system's automation level and operational reliability. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for preventing blockage of the conveying pipeline for potassium carbonate conveying.

[0008] A device for preventing blockage in a potassium carbonate conveying pipeline includes a pneumatic air hammer and a control system. The control system controls the air hammer to strike a predetermined position on the conveying pipeline at a predetermined frequency according to a preset program. The air hammer is connected to the conveying pipeline through an installation structure.

[0009] The installation structure includes a support frame, which includes a support column. The upper end of the support column is connected to one end of a support channel steel, and the other end of the support channel steel is connected to one end of a support rod. The other end of the support rod is connected to the middle section of the support column. A limiting sleeve is provided on the upper surface of the support channel steel. The limiting sleeve is a U-shaped bent piece. The outer sides of both ends of the limiting sleeve are threaded. The two ends of the limiting sleeve pass through the through holes on the upper surface of the support channel steel and are locked with nuts. A pneumatic air hammer is fixed between the limiting sleeve and the support channel steel.

[0010] Preferably, the pneumatic air hammer includes a cylinder body and a magnetic piston. The cylinder body has a chamber, and a base plate is provided in the middle section of the chamber. A through hole is provided at the center of the base plate. One end of the chamber is connected to an air compressor through an air pipe.
