Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, in particular to a kiln feeding device. Background Art

[0002] Manual feeding is the most traditional way of feeding the kiln, and workers generally manually load the raw materials into the kiln. Commonly used raw materials include white charcoal, defoaming agent, asphalt, etc. Manual feeding has the following advantages: 1. Strong flexibility: Manual feeding is suitable for small production scenarios because it does not require special equipment and can be fed quickly. In addition, manual feeding can be adjusted according to actual needs, and it is very flexible. 2. Low cost: Manual feeding does not require expensive equipment and maintenance costs, which can reduce production costs. However, manual feeding also has some disadvantages: 1. Low production efficiency: Manual feeding requires a lot of manpower, which will reduce production efficiency and restrict production scale. 2. Improper operation of workers: Since the kiln is a high-temperature production equipment, improper feeding by workers may cause safety accidents such as fire.

[0003] Automatic feeding is a feeding method that has emerged in recent years with the development of industrial automation trends. Raw materials are fed into the kiln through automated equipment. Commonly used automatic feeding equipment includes lifting machinery, conveyor belts, ejectors, etc. Automatic feeding has the following advantages: 1. Improve production efficiency: Automatic feeding equipment can replace a large amount of manpower to complete tedious and repetitive feeding operations, thereby improving production efficiency. 2. Improve production quality: Automatic feeding equipment has high precision and good repeatability, which can ensure the stability and accuracy of raw material feeding. However, automatic feeding also has some disadvantages: 1. High equipment maintenance cost: Automatic feeding requires expensive equipment, and poor equipment will cause production stagnation or even accidents. 2. Inflexible: Automatic feeding is suitable for large-scale production scenarios and does not have the flexibility of manual feeding. At present, automatic feeders for liquid materials such as defoamers can only complete the feeding process once, which is difficult to ensure that the liquid is fully utilized and generally lacks distribution uniformity. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the automatic feeder for liquid materials such as defoaming agents can only complete the feeding process once, which makes it difficult to ensure that the liquid is fully utilized and generally lacks distribution uniformity.

[0005] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:

[0008] Preferably, a heat insulation layer is provided outside the furnace body.

[0009] Preferably, the diameter of the lower section of the furnace body is larger than the diameter of the middle section, and the top surface of the upper section of the furnace body is a conical surface.

[0010] Preferably, the conical surface is provided with a plurality of linear grooves extending radially along the conical surface, and the ends of the linear grooves are located at the lower side of the output tube.

[0011] Preferably, the stirring shaft of the impeller is arranged horizontally, and the stirring shaft forms an angle of 10 to 15 degrees with the horizontal plane.

[0015] In the structure of the utility model, the liquid tank is the source or temporary storage container of the liquid. The preheating tank preheats the liquid before feeding. The filter plays a preliminary filtering role, which helps to reduce the impurities in the liquid. The kiln is a calcining device, and its furnace body is a calcining space. The liquid that is not fully utilized may accumulate at the bottom of the furnace body. Under the action of the reflux pump, it is led out through the reflux pipe, and then returned to the middle section of the furnace body through the liquid inlet pipe, and ejected from the distributor. The scattered fluid is reused here, ensuring the utilization rate. The motor drives the impeller to rotate in the lower section of the furnace body, which plays a role in moving the liquid at the bottom of the furnace body to keep it in a relatively homogenized state. The baffle plays a role in blocking and disturbing the flow in this process. The smoke generated by calcination runs upward and is filtered by the filter screen to remove impurities. The input pipe can be used to feed the furnace body for the first time. The output pipe transports the smoke to the exhaust pipe for further discharge. The heat exchanger plays a role in recovering waste heat from the smoke in this process.

[0016] The utility model discloses a kiln feeding device. This technical innovation designs a dual-channel feeding path and adds a recycling mechanism for liquid materials, thereby improving the utilization rate of materials while fully ensuring the feeding efficiency. The utility model has a reasonable structure and is easy to carry out technical transformation on the basis of the current vertical kiln structure. BRIEF DESCRIPTION OF THE DRAWINGS
