Automatic hydraulic molding machine for pulverized coal

Abstract

The invention provides an automatic hydraulic molding machine for pulverized coal. The machine mainly comprises a frame, a molding mechanism, a feeding mechanism, a pushing mechanism, a hydraulic control system and an electrical control system, wherein the pushing mechanism is arranged on one side of the frame; the molding mechanism is arranged on the upper part of the pushing mechanism through apillar; the feeding mechanism is arranged on the frame; and the feeding mechanism mainly comprises a feeding cylinder, a storage hopper, a feeding cart, a conveying plate and a feeding belt, the storage hopper is arranged on the frame through a mounting bracket, the feeding belt is arranged at the opening of the upper end of the storage hopper, the feeding cart is arranged on the lower side of the storage hopper, and the feeding cart is connected with the feeding cylinder. The device optimally integrates the feeding mechanism, the molding mechanism and the pushing mechanism, and is cooperatedwith constant material feeding and discharging molded blocks to ensure that the whole production process does not require staff on duty, thus the device has the advantages of high automation degree, good production continuity performance and high production efficiency improved by over 2 times, and can be widely applied to industrial production.

Description

[0001] technical field [0002] The invention relates to the field of pulverized coal molding machinery, in particular to a pulverized coal automatic hydraulic molding machine. Background technique [0003] In recent years, the state has vigorously advocated and promoted energy-saving, carbon-saving, and non-polluting production models. The new environmentally friendly coke ovens and coal gangue brick-fired ovens are becoming more and more perfect, which can alleviate the shortage of energy and raw materials that restricts economic development to the greatest extent. However, there is currently a lack of dedicated rapid powder material pressing and molding equipment. The process of "manual feeding-friction press molding-manual return" is generally used in production. The production efficiency is low and personal safety accidents occur frequently. Due to the friction press The forming pressure is affected by human operation, which is often far from the marked tonnage. The com...

Problems solved by technology

However, there is currently a lack of dedicated rapid powder material pressing and molding equipment. The process of "manual feeding-friction press molding-manual return" is generally used in production. The production efficiency is low and personal safety accidents occur frequently. Due to the friction press The forming pressure is affected by human operation, which is often far from the marked tonnage. The compactness of the pressed profile cannot meet the requirements of environmental protection coking and coal gangue brick making. The pulverized coal forming machines sold on the market mainly include the following types: 1. Extrusion-type briquette machine, the publication number is CN1063074, which has a simple structure and small volume, but the production efficiency of this mechanical product is low, and the degree of automation is not high

2. Small continuous extrusion mobile briquette machine, whose publication number is CN86217812. This kind of mechanical product is relatively material-saving, low-noise and easy to use, but it still cannot be popularized and used due to its low degree of automation. 3. Powder Coal hydraulic automatic forming machine, whose publication number is CN2182332, is characterized in that hydraulic control elements control oil cylinders to act sequentially to extrude pulverized coal, but due to the imperfect design of its feeding mechanism and forming mechanism, the product forming performance is poor , The production continuity is not high and the structure is complex, so it cannot be used in industrial production. Due to the above factors, it is necessary to provide a pulverized coal automatic molding machine with a high degree of automation and low price
