Description

The invention relates to beekeeping and can be used for melting apiary wax.

Steam wax furnaces are known, where the heating of wax raw materials occurs during mixing with water or a steam-water mixture. In this case, the wax melted by the wet method contains a lot of water, so it is further pressed. But at the same time, Merva (a by-product) contains a significant amount of wax (20 ... 50%,), which is extracted from waste only by centrifugation. The waste obtained with this method is sent for extraction to extract residual wax. In this regard, the search for a less costly method that provides the maximum extraction of wax from wax materials with minimal energy costs, is an urgent task.

There is a wax refinery with sources of infrared rays, containing a housing, inside of which a baking sheet for wax materials and a wax collector installed underneath are placed. In the hiding frame and on the lower surface of the pan placed infrared electric heaters (patent No. 2223642) [1].

The closest analogue is VTP-17 steam wax refinery [2].

An object of the invention is to develop an installation using microwave energy, which provides the intensification of the heat treatment process of apiary wax at reduced energy costs.

The specified technical result is achieved in that the microwave installation for refining apiary wax contains a cylindrical screen housing with inlet and outlet nozzles, inside of which a perforated cylindrical resonator chamber in the form of a drum of non-ferromagnetic material rotating in a vertical plane is coaxially mounted. Moreover, one of its base is made of dielectric material and serves as a door where an opening is provided for the grinding mechanism of the top. Parallel to this dielectric door, there is a common door of non-ferromagnetic material, where a chopper-top and a microwave generator unit are mounted so that the emitter is directed towards the drum. Between the resonator chamber and the screen housing, in the lower part of the installation, there is a tubular heating element.

Figure 1 shows a diagram of a microwave installation for refining apiary wax: 1 - screen housing; 2 - resonator chamber - drum; 3 - a door made of dielectric material; 4 - a common door of non-ferromagnetic material; 5 - chopper-top; 6 - microwave generator unit with emitter; 7 - heating element; 8 - output pipe; 9 - inlet pipe; 10 - wax raw materials; 11 - crushed wax raw materials; 12 - melted wax raw materials.

A microwave installation for refining apiary wax of continuous action (FIG. 1) contains a cylindrical screen housing 1. Inside it is a cylindrical resonator chamber 2 coaxially arranged in the form of a perforated drum of non-ferromagnetic material, with the ability to rotate in a vertical plane. To do this, a drive shaft is mounted in the base of the drum, and the second base is a dielectric door 3, which has an opening for the grinding mechanism (a set of knives and gratings) of the top 5. Parallel to this door is a common door 4 of non-ferromagnetic material, into which the microwave generator unit 6 is mounted so that the emitter is directed towards the drum. The grinding mechanism of the top 5 is docked with the hole on the dielectric door 3, and the feeding screw and the drive of the top 5 are located outside the door 3. In the gap between the drum 2 and the screen housing 1, there is a heating element 7 in the lower part of the installation. The screen housing contains an outlet 8 and input 9 nozzles. The initial wax raw material 10 is loaded into the receiving pipe of the grinder; the crushed wax raw material 11 enters the cavity 2. The melted wax raw material 12 flows through the perforation of the resonator chamber 2.

The process of heat treatment of apiary wax is as follows. Wax raw material 12, freed from the frames and wires, is loaded into the receiving hopper of the grinder-top 5. Using an electric drive, the grinder-top 5 is turned on, the microwave generator unit 6 is turned on at the same time, and the valve on the inlet pipe 9 is opened. After that, the steam-water mixture enters through the perforation drum 2. The crushed wax raw material 11 enters the resonator chamber 2 and is moistened. After the accumulation of partial liquid in the drum 2, a tubular heating element 7 is included, which heats the steam-water mixture and partially melted wax that has leaked through the perforation of the drum. The crushed moistened apiary raw materials in the resonator chamber undergo endogenous heating due to the polarization currents of water dipoles under the influence of the microwave electromagnetic field and conductive heating from the hot surface of the drum. The microwave energy flux energy is directed into the resonator chamber 2 through the dielectric door 3. The drum made of ferromagnetic material is heated by melted wax 12. The melted wax is centrifuged through the perforation of the drum and continues to be heated by a tubular electric heater 7 (TEN). Such additional heating eliminates the solidification of the melted wax outside the cavity 2, and the outlet pipe 8 does not clog. The process of flushing occurs in flow mode, so the speed of unloading of finished products through the outlet pipe 8 is regulated by a valve. The melted wax 12 due to centrifugal force during the rotation of the drum (resonator chamber 2) seeps through the perforation. The steam-water mixture is fed continuously through the valve 9 into the screen housing 1. The rate of endogenous heating of the crushed raw materials due to the steam-water mixture increases sharply, and the quality and color of the finished product improve. After the accumulation of a certain precipitate (dead) in the resonator chamber, the installation should be turned off, open both doors 3.4 and clean the perforated resonator chamber 2 from solid sediment.

So, the proposed microwave wax refinery provides:

- loading pre-crushed wax raw materials into a perforated resonator chamber;

- supply of steam-water mixture into the resonator chamber;

- heating of raw materials due to the electromagnetic field of the microwave range and electric heater (TEN);

- centrifugation of molten wax;

- discharge of molten wax;

- unloading solid sediment from a perforated drum.
