Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal atomization equipment, and particularly relates to a split-type atomization device. Background Art

[0002] Generally, a centrifugal atomizer uses a high-speed motor to drive a gearbox, which is transmitted to the main shaft after speed change. The atomization disk is installed at the lower end of the main shaft. Materials enter the distributor from the feed pipe from top to bottom. The distributor evenly distributes the liquid material into the atomization disk for centrifugal atomization to obtain a product with smaller particles. There are discharge holes on the side of the atomization disk. The material moves outward under the action of centrifugal force and sprays outward through the discharge holes to achieve atomization. Some centrifugal atomizers work in cooperation with equipment such as high-temperature and high-pressure drying towers. The surface of equipment similar to the drying tower has a high temperature. The centrifugal atomizer is generally arranged in the center of the top of the tower, and the material is atomized downward from the top of the drying tower. This leads to two problems: 1. The surface temperature of the drying tower is very high. The cooling lubricating oil of the atomizer will lose its cooling effect and lubricating effect at high temperatures. The lubricating oil will accelerate oxidation at high temperatures, resulting in deterioration of the oil quality, manifested as a darker color, an increase in viscosity, etc. Acidic substances will also be generated during the oxidation process, and these substances can corrode metal components. High temperatures may cause the additives in the lubricating oil to decompose or fail, including anti-wear agents, rust inhibitors, and preservatives, etc., which will reduce the overall performance of the lubricating oil. Under high-temperature conditions, the lubricating oil may form carbon deposits and sludge. These deposits will not only clog the filter but also may exacerbate the wear of mechanical components. The base oil is the main component of the lubricating oil and also the carrier of the additives. If the base oil deteriorates due to high temperatures, then even if the additives still exist, they cannot play their due roles. At extremely high temperatures, part of the lubricating oil may evaporate, resulting in a reduction in the oil volume. 2. Since the centrifugal atomizer is located at the top of the extremely high-temperature drying tower, the maintenance and repair of the centrifugal atomizer equipment require the drying tower equipment to be shut down, and maintenance personnel can only climb to the top of the tower for maintenance after it cools down, which wastes time and reduces work efficiency. And the top of some drying towers has a sunken structure, making it very inconvenient for maintenance personnel to carry out maintenance and repair. Content of the Utility Model

[0003] Technical Problem to be Solved by the Utility Model

[0004] Aiming at the technical problems that the lubricating oil of the existing centrifugal atomizer for high-temperature high towers fails due to excessive temperature, and it is difficult to maintain and repair with high maintenance costs, the utility model provides a split-type atomization device, which can weaken the influence of high temperature on the lubricating oil of the centrifugal atomizer, and is more convenient for maintenance and repair. For the split part of the atomization device, when the temperature is not high, it does not need to stop the machine for repair, and the split part can be directly maintained and repaired.

[0005] Technical Solution

[0006] To solve the above problems, the technical solution provided by the present utility model is as follows:

[0007] A split-type atomization device includes an atomizer with a lubrication structure containing lubricating oil; an external oil pump mechanism, which is separately arranged from the atomizer and is arranged on an operating platform. It includes an oil pump, an oil tank, a condenser and pipelines. The oil pump is connected to the oil tank. A cooling coil is provided in the condenser. The cooling coil is provided with an oil inlet and an oil outlet and is connected to the oil tank. A circulating coolant is filled outside the cooling coil. The oil inlet is connected to the lubrication structure through a pipeline.

[0008] The external oil pump mechanism is separately arranged from the atomizer and includes an oil pump, an oil tank, a condenser and pipelines. The oil pump mechanism is separated from the atomizer body and can be maintained independently. The atomizer is equipped with a high-speed rotating motor and needs to be lubricated and cooled through the lubrication structure. The cooling coil is arranged in the condenser and is used to cool the lubricating oil. The circulating coolant circulates outside the cooling coil, absorbs the heat in the lubricating oil and reduces the temperature of the lubricating oil. The cooled lubricating oil is transported to the lubrication structure of the atomizer through a pipeline. The oil pump mechanism is arranged on the operating platform, which is convenient for maintenance personnel to approach. When the temperature of the separated part is not high, maintenance can be carried out directly without waiting for the entire drying tower to cool down.

[0009] Optionally, a pressure transmitter is connected to the oil inlet of the condenser.

[0010] By monitoring the pressure of the lubricating oil before it enters the cooling coil, it can be ensured that the lubricating oil can flow smoothly into the cooling system. If the pressure of the lubricating oil is abnormal (too high or too low), the pressure transmitter can issue an alarm in time to prompt the operator that there may be blockage or other problems. By monitoring the pressure change of the lubricating oil, it can be predicted when maintenance is required, such as cleaning the filter or replacing the lubricating oil.

[0011] Optionally, the condenser is provided with a liquid outlet and a liquid inlet. The liquid outlet and the liquid inlet are connected to a coolant tank, and the coolant tank is connected to a water pump.

[0012] The coolant tank stores the coolant, and the water pump is used to pump the coolant from the coolant tank into the cooling coil of the condenser. The coolant enters the condenser through the liquid inlet from the coolant tank. The coolant flows out of the cooling coil and returns to the coolant tank through the liquid outlet.

[0013] Optionally, the liquid inlet is located below and the liquid outlet is located above.

[0014] Coolant enters from the bottom of the coolant tank. At this time, the coolant temperature is relatively low and the density is relatively high. The cooled coolant is discharged from the top of the coolant tank. At this time, the coolant temperature is relatively high and the density is relatively low. And the liquid inlet from the bottom can naturally fill the entire condenser, and there will be no situation where the coolant is discharged without absorbing much heat.

[0015] Optionally, the cooling coil is spiral.

[0016] The spiral design increases the surface area of the cooling coil, which means there are more opportunities for heat exchange, thus improving the cooling efficiency. The spiral structure helps to guide the coolant to flow along the pipe wall, reduces the occurrence of turbulence, improves the laminar flow effect of the fluid, and is beneficial to heat exchange.

[0017] Optionally, the cooling coil is made of a metal material with high thermal conductivity.

[0018] The metal material can quickly transfer the heat in the lubricating oil to the coolant.

[0019] Optionally, a bracket is provided below the pipeline.

[0020] In high-temperature or low-temperature environments, the bracket can provide a certain heat insulation effect, reduce heat transfer, and protect the pipeline from the influence of temperature changes. The bracket makes the pipeline easier to access, facilitating daily inspection and maintenance.

[0021] Optionally, the external oil pump mechanism is arranged on the bracket.

[0022] The bracket can provide a stable support for the oil pump mechanism to ensure its stability during operation. The bracket can provide a certain heat insulation effect, reduce heat transfer, and protect the external oil pump mechanism from the influence of temperature changes.

[0023] Beneficial effects

[0024] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0025] In the technical solution provided by the present utility model, the atomizer includes a lubricating structure with lubricating oil; an external oil pump mechanism, which is separately arranged from the atomizer, is arranged on the operation platform, and includes an oil pump, an oil tank, a condenser and a pipeline. The oil pump is connected to the oil tank. The condenser is provided with a cooling coil. The cooling coil is provided with an oil inlet and an oil outlet and is connected to the oil tank. The outside of the cooling coil is filled with circulating coolant. The oil inlet is connected to the lubricating structure through the pipeline. It can weaken the influence of high temperature on the lubricating oil of the centrifugal atomizer, and is more convenient for maintenance and repair. For the separated parts of the atomizing device, when the temperature is not high, it is not necessary to stop the machine for repair, and the separated parts can be directly maintained and repaired.

[0031] Embodiment

[0032] Combined with the attached Figure 1 , a split atomization device includes an atomizer 1, an external oil pump 202 mechanism 2, a pipeline 3, a bracket 4, and an operation platform 5. The split atomization device is located at the top of a drying tower 6. The center of the top of the drying tower 6 is a sunken structure. The atomizer 1 includes a lubricating structure with lubricating oil. The atomizer 1 is equipped with a high-speed rotating motor and needs to be lubricated and cooled through the lubricating structure. The atomizer 1 is located in the sunken structure, which is inconvenient for maintenance and repair. The external oil pump 202 mechanism 2 is placed on the operation platform 5, which is convenient for maintenance and repair. And the external oil pump 202 mechanism 2 is arranged on a bracket 209. The bracket 209 is made of high-strength metal materials such as carbon steel and stainless steel to ensure sufficient load-bearing capacity and durability. The bracket 209 is installed on the operation platform 5 by means of welding, bolt fixation, etc. In some cases, the bracket 209 can be designed to be height-adjustable to facilitate the operation of maintenance personnel.

[0033] Combined with the attached Figure 2, the external oil pump 202 mechanism 2 is separately arranged from the atomizer 1. The external oil pump 202 mechanism 2 includes an oil pump 202, a fuel tank 208, a condenser 203 and a pipeline 3. The oil pump 202 is connected to the fuel tank 208. A cooling coil 20301 is provided inside the condenser 203. The cooling coil 20301 is provided with an oil inlet 204 and an oil outlet 205 and is connected to the fuel tank 208. A circulating coolant is filled outside the cooling coil 20301. The oil inlet 204 is connected to the lubrication structure through the pipeline 3. The condenser 203 is provided with a liquid outlet 206 and a liquid inlet 207. The liquid outlet 206 and the liquid inlet 207 are connected to a coolant tank, and the coolant tank is connected to a water pump. The liquid inlet 207 is located below, and the liquid outlet 206 is located above.

[0034] A bracket 4 is provided below the pipeline 3. The bracket 4 is inserted on the slope of the sunken structure to provide stable support, ensuring that the pipeline 3 will not be displaced or damaged when subjected to external forces (such as vibration, weight, etc.). And in high-temperature or low-temperature environments, the bracket 4 provides a certain heat insulation effect, reducing heat transfer and protecting the pipeline 3 from the influence of the high-temperature drying tower 6.

[0035] The working principle in the external oil pump 202 mechanism 2 is as follows: Lubricating oil circulation: The oil pump 202 pumps the lubricating oil from the fuel tank 208 into the cooling coil 20301. Heat exchange: Inside the cooling coil 20301, the lubricating oil exchanges heat with the external coolant, and the coolant absorbs the heat in the lubricating oil. Coolant circulation: The coolant enters from the liquid inlet 207 of the cooling coil 20301, flows out from the liquid outlet 206 after heat exchange, and returns to the coolant tank. Lubricating oil delivery: The cooled lubricating oil is delivered to the lubrication structure of the atomizer 1 through the pipeline 3 to ensure the normal operation of the atomizer 1. Coolant circulation system: The coolant tank is connected to a water pump, and the water pump pumps the coolant into the cooling coil 20301 to circulate and maintain the cooling effect.

[0036] A pressure transmitter 201 is connected to the oil inlet 204 of the condenser 203. The working principle of the pressure transmitter 201 is as follows: Pressure conversion: The pressure transmitter 201 converts the pressure signal of the lubricating oil into an electrical signal (such as a 4-20 mA current signal); Signal transmission: The signal is transmitted to the control system or monitoring instrument through a cable; Data reading: The control system or monitoring instrument can read and display the pressure data for the operator to monitor. By monitoring the pressure change of the lubricating oil, preventive maintenance measures can be taken before problems occur to avoid unexpected shutdowns. When problems occur in the system, the cause of the problem can be diagnosed by analyzing the pressure data of the lubricating oil. Long-term monitoring of the pressure of the lubricating oil helps to optimize the performance of the cooling system and ensure that the atomizer 1 operates in the best state.

[0037] Combined with the attached Figure 3, the cooling coil 20301 is spiral. The cooling coil 20301 is made of a metal material with high thermal conductivity. Copper, aluminum, or stainless steel can be used. Copper is a commonly used high-thermal-conductivity material with excellent thermal conductivity. Aluminum is also a material with good thermal conductivity, and it is lighter in weight. Although the thermal conductivity of stainless steel is not as good as that of copper or aluminum, it has good corrosion resistance and is suitable for certain special application scenarios.

[0038] The above has schematically described the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
