Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal atomization equipment, in particular to a preheating atomization device. Background Art

[0002] The centrifugal atomizer generally uses a high-speed motor to drive the gearbox, which is transmitted to the main shaft after speed change. The atomizer disk is installed at the lower end of the main shaft. The material enters the distributor from the top to the bottom of the feed pipe. The distributor evenly distributes the liquid into the atomizer disk for centrifugal atomization to obtain a product with smaller particles. There is a discharge hole on the side of the atomizer disk. The material moves outward under the centrifugal action and sprays outward at the discharge hole to achieve atomization. A high-speed rotating motor is installed in the atomizer, and the atomizer disk is driven to rotate through the transmission shaft to atomize the material. Lubricating oil lubrication is required at the transmission shaft. In cold areas, when the atomizer is started by a cold machine, the ambient temperature is low, the lubricating oil is thick, the fluidity is poor, the oil pump cannot absorb oil, and the atomizer cannot work normally. When the lubricating oil temperature is too high, the lubricating oil will lose its lubricating effect, because the lubricating oil will accelerate oxidation at high temperature, causing the oil to deteriorate, which is manifested as darker color and increased viscosity. Acidic substances will also be produced during the oxidation process, which can corrode metal parts. In addition, high temperatures may cause the decomposition or failure of additives in lubricating oil, including anti-wear agents, rust inhibitors and corrosion inhibitors, which will reduce the overall performance of the lubricating oil. Under high temperature conditions, lubricating oil may form carbon deposits and sludge, which will not only clog the filter, but also increase the wear of mechanical parts and shorten the service life of the equipment.

[0003] Technical problems to be solved by utility models

[0004] In view of the technical problem that when the existing atomizer starts a cold machine, when the ambient temperature is low, the lubricating oil is thick and has poor fluidity, the oil pump cannot absorb oil, and the atomizer cannot work normally, the utility model provides a preheating atomization device, which can heat the lubricating oil at a constant temperature and has a balanced heating effect, effectively solving the problem of thick lubricating oil, poor fluidity, and the inability to start the cold machine.

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the utility model is:

[0007] A preheating atomization device comprises an oil tank, to which a heater and a temperature sensor are sealed and connected, the heater and the temperature sensor are both connected to a controller, the side wall of the oil tank is an inclined surface, the heater is provided with a heating resistance wire whose length matches the length of the side wall, and the heater is installed inside along the direction of the inclined surface.

The temperature measuring sensor is installed at the top of the fuel tank by means of a mounting sleeve and a threaded connection, which is convenient for installation and maintenance.

[0017] Optionally, the heat conducting rod is made of stainless steel material.

Uniform heating can reduce the situation of local overheating or unheated areas, improve the starting efficiency and operating efficiency of the atomizing device. By uniformly heating the lubricating oil, the fluidity of the lubricating oil can be improved, making it easier to start the cold machine.

[0021] Optionally, the heating resistance wire is made of stainless - steel material.

[0033] The mounting sleeve is provided with a groove for accommodating a sealing ring 704, and the sealing ring 704 is arranged in the groove. The groove is an annular groove, and the diameter of the sealing ring 704 is larger than the width of the groove of the annular groove, so that the sealing ring 704 can be extruded to improve the sealing performance.

[0034] The groove is arranged at the bottom of the mounting sleeve, and the sealing ring 704 is an axial seal. The sealing ring 704 is located between the mounting sleeve and the fuel tank 7, and is mainly squeezed by the thread fastening force of the mounting sleeve and gravity to improve the sealing performance.

[0038] Working principle:

[0039] The temperature sensor 701 monitors the temperature of the lubricating oil in the fuel tank 7 in real time and sends the data to the controller.
