Description

This invention relates to a technology for extracting viscous products from containers and can be used in the chemical, chemical, optical and other industries. A device for the melting of rosin is known, in which the melting and removal of the rosin block from the container occurs upon contact with the hot pipes of the melter 1. The disadvantages of this device are the large size, relatively low productivity, due to the rosin It melts only at the point of contact with fixed pipes, the surface of these contacts is limited. A device for extracting viscous products from containers is known, comprising a base, a table for containers mounted thereon. And heaters 2, which are firmly mounted with the possibility of a returnable movement, However, despite high heat exchange coefficients and the presence of circulating stirring of the liquid, the rate of transition of the frozen rosin into the liquid the state remains insufficiently high due to the fact that intensive mixing of the fluid is observed only at the heater surface and does not extend to a highly viscous layer adjacent to the solid material, which is the main thermal resistance to heat transfer to the solid material. The aim of the invention is to increase productivity by intensifying the melting process. The goal is achieved by the device for removing viscous products from containers, containing a base, a table for containers and a rack mounted on it, and heaters fixed with the possibility of reciprocating movement, equipped with a carrier mounted on the rack with a carriage divided by it with the possibility of radial movement ; the heaters are located in the carriage, and the table or carrier has the ability to rotate around a vertical axis. The device is equipped with a heating control system consisting of resistance sensors for radial displacement of heaters, temperature sensors of heaters and a control unit. Heaters in the carriage mounted in the bearing. Fig. 1 is a schematic illustration of a mouth (an arrangement for removing viscous products from containers by heating them to a liquid state with a immersion heater that moves radially, and the tank has a rotational movement around its axis; Fig. 2 is a side view the device shown in Fig. 1; in Fig. 3 the heater is rotatable around its axis; in Fig. 3 is a side view of the device shown in Fig. 3; Fig. 1 schematically shows a device in which the heater moves in a spiral; Fig. 6 is depicted with device 1. A table for containers 3, a rack k with a platform carrying the reciprocating movement 6 and a carrier 7 with a carriage 8 placed on it carrying the heater 9 are mounted on the base 1. The carriage has a radial movement mechanism, for example, a screw the transmission is kinematically connected with the reversible motor 10, and the table is a rotation mechanism 11, clamps 12 are used to strengthen and center the container on the table, and pump 13 and pipeline k are used for siphoning fluid. The mechanisms 6 and 10 for reciprocating the platform and the radial movement of the carriage are, for example, a helical gear with a reversible electric motor. The mechanism 11 of rotation of the capacitance. It is an electric motor with a gearbox, the output shaft of which is coupled to the axis of the table, which is fixed in the bearing. The carriage 8 is rigidly connected to the heater 9 and is moved along the carrier guides with the aid of a radial movement mechanism. H 9 The heater is, for example. measures, a heat-electric heater with a preferential heat release at the lower end to improve the process of immersion and heating, the Device. FIG. 3 differs from the device shown in FIG. 1, 2 in that the heater E is fully rotation around its axis. For this, the device has a bearing 15 and a collector device 16 for supplying voltage to the heater. FIG. 5 shows the variant when the heater moves in a spiral with the help of a carrier 7 having a rotation mechanism 17 and a spring mechanism 18 for imparting radial movement of the carriage 8. The spring mechanism is activated with a latch 19, In the control circuit of the device (Fig. 6) shows the heater pump 20, its vibration drive 21, the tank rotation mechanism 11, the radial movement resistance sensor 22, the heater temperature sensor 23, the control unit 2i and the actuator 25 that turns on and adjusts its voltage to the heater, as well as radial movement mechanism 10, przhimayuschego heater to the molten material. The device works as follows. The containers 3 are placed on the table 2 and with the help of clips 12 they center and fix it on it. Capacity razlukovyvayut. The heater 9 is installed opposite the hatch and heated to the desired temperature, after which it is inserted into the material, activating the drive of the reciprocating movement 6. After the heater 9 is immersed, the mechanisms 10 and 11 of the heater radially move and the container rotates into the material. When moving the heater 9 from the center to the periphery of the container and simultaneously rotating the container 3, a contact is created between the heater and the unmelted material. After all the material has been melted, the heater is brought by means of the mechanism of radial movement 10 to the center of the container 3 and by means of the mechanism of reciprocating movement 6 it rises to its original position. Melt from tank

the pump 13 is pumped out. The empty tank is replaced with a filled material, and the cycle is repeated.

The introduction of the heater into the material can be carried out by means of lifting the table. When using a pump heater, there is no need to install a special pump. -.

The operation of the device shown in FIG. 3, is similar to the operation of the device shown in FIGS. 1, 2, only the heater 9 rotates around its axis due to frictional coupling between the surface of the heater 9 and the unmelted material.

The operation of the device, when it is used to transfer the material into a liquid state and remove it from the tank 3 of the pump heaters, is regulated as follows. In the process of immersion, heat-; the bodies of the pump 20 into the material and its heating using a temperature sensor 19, for example, a thermocouple and a potentiometer, measure the temperature. Measurement data is fed to a control unit, which compares it with a predetermined value and outputs a control signal to the actuator 25, which regulates the heat release. After immersion of the Heater 20, the rotation mechanism 1 1, the radial movement mechanism 10 of the heater 20 from the center to the periphery of the tank are activated, the vibratory drive 21 of the heater and simultaneously with the help of the sensor 22 the resistance of the radial movement of the heater is measured, which outputs a control signal to the actuator 10. & LOK control 2f can carry out the radial displacement of the heater-pump and heat supply according to a specific program.

The experiments confirmed the high efficiency of conversion to liquid state and the extraction of rosin and other materials from tanks by immersion heaters, having the possibility of spiral movement relative to the material and being in contact with solid material.

material. The time of conversion of the rosin into liquid in a vessel with a diameter of мм mm and a height of 300 mm is О им im with a heater power of 2 kW and a rotational speed of the vessel tO r / min. The rosin in the cardboard drum is transferred to the liquid state and pumped out with a submersible vibration heater-pump for 140-50 minutes with a heater power of 8 kW.
