Description

The utility model relates to a device for heating grease conservation lubricants and subsequent pneumatic spraying of the heated lubricant onto surfaces protected from corrosion and can be used to apply the said lubricant to the outer surfaces and, partially, the inner surfaces of elements of agricultural machines.

A known installation is OPU-80 for the preparation of thickened lubricant [1]. The installation contains a thermally insulated tank with a capacity of 80 liters with a mixing device; 3 kW heating element burners are located under the bottom of the tank; a control panel is located on the side wall.

The disadvantages of the known installation are large heat losses, since the heating element burners transfer heat to the bottom of the tank; high power consumption; The heated conservation material is dispensed by gravity.

A device for pneumatic spraying of heated viscous anti-corrosion lubricant is known (patent RU 206408 U1) [2]. The device contains a tank for a viscous anti-corrosion composition placed inside the tank with coolant. The coolant is heated using an electric heating element from a washing machine, with a voltage of 220 volts, installed in the lower part of the tank. The temperature is controlled by a temperature sensor and regulated by a PID controller.

One of the disadvantages of this installation is that it requires electricity to operate. Therefore, it is impossible to use the installation when preserving equipment in open areas without electricity.

In addition, the heating element is located at the bottom of the coolant tank, and the material tank does not have a mixing mechanism, which together does not ensure uniform heating of the lubricant in the tank.

The purpose of the utility model is to create a simple design of a device for heating a plastic conservation lubricant, reducing energy costs for heating the lubricant, and achieving more uniform heating of the lubricant.

The technical result of the claimed utility model is achieved due to the fact that the claimed device contains a coolant tank, inside of which a coil is mounted, through which exhaust gases from the exhaust gas exhaust system of an internal combustion engine of a tractor or car pass, thereby ensuring uniform heating of the coolant in the tank without using electricity.

In the tank for conservation grease there is a stirrer shaft with spiral blades installed on it; when the shaft rotates, the lubricant in the tank is mixed, and the lubricant in the tank is evenly heated.

The developed device is designed to heat a plastic conservation lubricant, while the heating of the lubricant occurs due to the passage of exhaust gases from an internal combustion engine through a coil.

In fig. 1 - device for heating plastic conservation lubricant;

in fig. 2 - its top view.

The device contains a tank for conservation greases 1 (Fig. 1), into the lower part of which a fitting 2 is screwed in for connecting a distribution hose with a spray gun. A flange is welded to the top of tank 1. Tank 1 for conservation greases is welded into coolant tank 3, in the top cover 4 of which fittings 5 are welded for filling it with coolant. The cover 7 of the tank for conservation grease 1 is secured with four wing nuts 9 (Fig. 2). In addition, the cover 7 contains a bearing assembly 6 and two fittings 8, to one of which a pneumatic line is connected to create pressure inside the tank for grease conservation lubricants 1. If the pneumatic line does not have a reducer, then instead of a plug on the second fitting 8, a pressure reducing valve can be installed to maintain the required pressure inside the tank for conservation greases 1.

Inside the coolant tank 3, a coil 10 is installed along its entire length, to the bottom of which an inlet pipe 12 is attached for connection to the engine exhaust system. In the upper part of the coil 10 there is an outlet pipe 13 for releasing gases into the atmosphere.

In the tank for conservation grease 1, a stirrer shaft 14 with spiral blades 11 installed on it is fixed. The stirrer shaft 14 rotates in the bearing unit 6, the upper part of the stirrer shaft 14 is made in the shape of a square (Fig. 2), for the possibility of attaching a screwdriver or wrench ratchets.

Coolant tank 3 is installed on stand 15.

A device for heating grease conservation lubricants operates as follows. Through fitting 5, coolant tank 3 is filled with coolant, for example waste oil.

The device is connected through the inlet pipe 12 to the exhaust gas system of the engine, which warms up to operating temperature. The exhaust gases pass through the coil 10, and thereby evenly heat the coolant in the coolant tank 3, while the grease in the tank 1 is heated, and the exhaust gases exit through the pipe 13.

The operator periodically rotates the shaft 11 in the bearing unit 6, putting a ratchet wrench or a screwdriver on its upper outer part. Blades 11 on shaft 14 mix the lubricant in tank 1, which ensures its uniform heating.

To dispense the heated plastic conservation lubricant, air is supplied to fittings 8. Under the influence of air pressure, the heated lubricant is supplied to fitting 2, from where it is subsequently fed into the spray gun and applied to the protected surfaces.

The advantages of this device are:

simplicity of design;

reducing the cost of heating conservation material through the use of engine exhaust gases;

uniform heating of the anti-corrosion preservation composition due to the use of a shaft with blades;

dispensing of conservation material can occur under pressure, also from the pneumatic system of a tractor or car;

high reliability of the device, since there are a minimum of electrical components.
