Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, in particular to a heating device used for melting a compound fertilizer anti-caking agent. Background Art

[0002] The compound fertilizer anti-caking agent is a solid material. When used, it needs to be heated and sprayed on the fertilizer through the spray device in the wrapping machine to form an anti-caking layer on the surface of the compound fertilizer to prevent the fertilizer from caking. The traditional process is to lift the anti-caking agent into the oven through an electric hoist, and carry out the mass transfer and heat exchange reaction of the oil agent under the action of the steam coil in the oven. However, since the mass transfer reaction is affected by the contact area and mass transfer effect of the three phases of gas, liquid and solid, two ovens need to be set up for each production line, and the length of each oven is about 4 meters. In summary, the existing anti-caking agent heating system has the following defects: 1. Due to the low efficiency of the three phases of gas, liquid and solid, not only the heating and melting efficiency of the anti-caking agent is low, but also the energy consumption cost of producing steam will be directly increased; 2. Large hoisting equipment is required, and safety risks are prone to occur during the hoisting process of the anti-caking agent. 3. The above equipment occupies a large area. Utility Model Content

[0013] A heating device for melting anti-caking agents for compound fertilizers made in accordance with the above scheme overcomes the problems of reverse transportation and hoisting required in traditional technologies by setting up an open-and-close induction unit, thereby increasing the safety of the anti-caking agent melting process. When the anti-caking agent for compound fertilizer needs to be further heated by melting, the oil barrel containing the anti-caking agent is placed between the first electromagnetic inductor shell and the second electromagnetic inductor shell and heated directly by electromagnetic means.

The utility model is mainly used for heating and melting compound fertilizer anti-caking agent, which is different from the steam heating method used in the traditional technology. Instead, the anti-caking agent oil barrel 2 is used as a container, and the first electromagnetic induction shell 6 and the second electromagnetic induction shell 7 that can be opened and closed are provided to facilitate the placement of the anti-caking agent oil barrel 2, reduce the equipment footprint and save energy consumption; the first electromagnetic induction shell 6 and the second electromagnetic induction shell 7 are provided with induction coils, which can be directly purchased on the market, and their structures are not repeated; after the electric energy passes through the induction coils, a magnetic field is formed, and the alternating magnetic lines of force in the magnetic field pass through the magnetic conductive anti-caking agent Eddy currents are generated in the anti-caking agent oil barrel 2, causing the anti-caking agent oil barrel 2 to heat up at high speed, and heat is exchanged with the oil in the barrel through heat conduction. During the working process, the 380V, 50 / 60Hz alternating current is rectified into direct current through the rectifier circuit, and then the direct current is converted into voltages of different frequencies through the control circuit. The current flowing through the coil will produce a changing alternating magnetic field. The alternating magnetic lines of force in the magnetic field will generate eddy currents in the magnetic conductive anti-caking agent oil barrel 2, causing the anti-caking agent oil barrel 2 to heat up at high speed, and heat is exchanged with the oil in the anti-caking agent oil barrel 2 through heat conduction. A temperature sensing device can be set in the sensor, and the power is automatically cut off after reaching the set temperature, and the heating ends. The utility model realizes the conversion of electrical energy and magnetic energy through electromagnetic induction magnetic heating, reduces the heating cost of the anti-caking agent oil, improves the melting efficiency of the anti-caking agent, and avoids unnecessary waste of electrical energy.
