The device consists of a main and additional intake pipe 1, which is a heating and intake pipe, a unit of the device, it produces heating and absorption of a viscous oil product that is drained from the tanks. The intake pipe is made of an elastic (flexible) material with plasticity and depending on the aggressiveness of the pumped product. Intake pipelines must be resistant to acids and alkalis, have heat resistance, strength,

Must be reinforced with cord, whether with wire or other materials.

In order to accelerate the discharge of viscous products from tanks, it is necessary to ensure flowability by heating the product - for this purpose, spiral pipe holes are made in the walls of pipelines 1 along the entire line of the coil 2, in which the coolant circulates - steam or water, maybe the same liquid (product) preheated outside the tank. In the lower part of the pipeline there is an intake pipe 3, the coil heater in it is made three-row - of three rows of spirals. The intake pipe itself can have not only three, but also one or more rows of spirals, which together with the heater spiral make up a single coil formed in its body - in its walls. The upper part of the pipelines ends with a thread, and its end has two holes - the beginning and end of the coil.

The pipe thread for strength can be metallized or made of metal and poured into the pipe 1. The pipe 1 is worn on the nozzle 4, which serves to connect it to a drain pipe into which the container is unloaded. In the end part of the nozzle 4 there are two threaded holes, into which the fittings 5 are screwed on, tubes b with flanges are welded to the nozzle 4 on the back of the threaded holes, with which the coolant is supplied and removed to heat the pipe, for fixing the nozzle 4 there is a flange 7. Pipe 1 the nut 8 is pressed against the nozzle 4 by means of handles 9, for fixing the nut 8 on the nozzle 4 there is a flange 10. When installing pipelines, the inlet and outlet openings of the coil are mounted on the fittings 5 and the nuts 8 are screwed.

Pipelines 1 can be electrically heated when, instead of a coil heater for the heat carrier, an electric coil 11 is inserted into their walls, the ends of which exit to the box 12. The nozzle 4 of the pipe 11 with a flange 7 is attached to the expansion chamber 13 of the drain pipe. The expansion chamber 13 has two flanges 14 to which two nozzles 4 are attached. Flanges 14 are equipped with indicators 15 for the presence of liquid in the nozzle for monitoring the discharge. A pipe 16 is connected to the chamber 13 to fill the pipe outlet of the drain pipe with the same draining liquid to create a siphon when the device operates without a pump, i.e. no forced suction of oil from the tank.

The operation of a device for heating and draining viscous products from a container is carried out as follows;

After installing the tank (tank)

for unloading, one pipeline is first lowered into the tank, then, when it is laid, the second one is lowered; they are lowered through the neck with a hoist. If the fluid is viscous or consistent, and the pipelines are not immersed, then open the valve of the pipe connected to the device tube 6, and steam or hot water is supplied through the nozzle 5 of the nozzle 4 to the pipeline heater, which after heat transfer

5 exits the coil heater through a branch pipe 6 (the other end of the heater). A heater heats the liquid or product in the container, which becomes less viscous, and the pipe easily immerses 0 s in the container. Touching the bottom of the tank, each pipeline under its own weight with continuous heating of the contents of the tank is laid on its bottom. Since the coolant constantly flows through the enamel heater, the corresponding pipeline easily moves along the bottom of the tank to one end wall, heating along the way to a viscous oil product. Coolant inlet and outlet

0, the coil heater is produced by tubes b, so that the constant circulation of the heat carrier is effected. When the first pipeline is laid, an additional pipeline is lowered and laid in the same way, moving it to the other end wall of the tank. When draining containers with non-flammable products, electrically heated pipelines are used, which simplifies the operation of the device and draining

0 in general, since the supply of coolant (steam, hot water) is not required, but only the connection of two drives to box 12. The voltage is connected from the 36 volt network through box 12, and all subsequent operations are carried out as with pipelines. Unloading of tanks (tanks) through the upper neck is carried out by a pump or by gravity, pre-filling the device and the drain pipe to which

0 it is connected, through a pipe 16, heated with the same liquid to ensure that the pump or gravity trap siphon contents of the tank (tank). In the manufacture of pipelines in their body (walls)

5, a flexible tube or flexible tape heaters may be infused.

Together with the drain through the device, the lower drain device can be opened and the drain is made through the lower drain hole of the tank container, since

Since the product in the tank (tank) is heated by the outer walls of the heater pipelines, it drains easily and quickly, thereby increasing the drainage capacity. Drain performance can be controlled both by an automatic controller, the actuator of which can be installed on the coolant supply, and the sensor on one of the pipelines immersed in the product, or by replacing the coolant with a more calorific one, as well as by increasing heat transfer, i.e. coolant circulation rates in the coil. The device can be used to accelerate the filling of containers (tanks) with viscous products - for this the device is lowered into the container from which the filling or dispensing of viscous oil products is made, the pump is turned on, and the heated product is easily and quickly pumped out or squeezed out of the container by pressure of the heat carrier. The use of a device for draining and filling containers improves the technical and economic conditions of the loading and unloading process when pumping, draining and filling containers (tanks) with viscous products, since the device has a high efficiency, expressed in the quick and complete draining of containers (tanks) In addition, it allows a mixed discharge of the tank (tank) through the neck - the upper loading and lower drain holes, i.e. increase discharge capacity, and this reduces the time the tank capacity is under discharge. 4When draining the product, its quality does not deteriorate, since there is no flooding of the product with steam condensate. The device can be used for draining and filling viscous products that previously had not been merged with existing devices, since they were mixed and dissolved in condensate,

The device provides a saving of heat carrier, since it returns heat carrier to regeneration, i.e. additional heating for reuse in heating. The device heats only that part of the product that 5 immediately removes from the tank (tank) and heat is not transferred through the walls of the tank (tank), especially in winter. The device provides the ability to control the rate of heating and draining of the product, which leads to savings in heat carrier and increase the efficiency of draining. The device produces proportional heating of the product using the amount of heat necessary to ensure

5 optimal fluidity of the product.

The device provides high efficiency for draining and filling containers (tanks), provides efficient heating of the product, creating savings in heat carrier

0 with a simultaneous increase in discharge performance, reduces downtime of tanks (tanks) under unloading and loading (discharge and filling), maintains the quality of the product being drained, and ensures the discharge of any products.
