Description

Technical Field

[0001] The invention relates to the technical field of paint film processing, and in particular to a portable and universal paint film processing device. Background Art

[0002] The paint film is an insoluble soft organic substance, usually composed of additives in the lubricating oil, oxidation products, fuel combustion products, etc. When the steam turbine and generator of a thermal power plant are running, the paint film in the lubricating oil will gradually accumulate, which will harm the normal operation of the equipment.

[0003] The following are some of the hazards of paint film:

[0004] 1. Reduced lubrication performance: The paint film will cover the surface of the lubricant, preventing the lubricant from contacting the metal surface, thereby reducing the lubrication performance. This will lead to increased friction between equipment parts, increased wear, and may even cause equipment failure.

[0005] 2. Affecting the heat dissipation effect: The paint film will form a heat-insulating layer on the surface of the equipment, which will affect the heat dissipation effect of the equipment. This will cause the temperature of the equipment to rise, accelerate the oxidation and deterioration of the lubricating oil, and further reduce the lubrication performance.

[0006] 3. Blocked bearings: Paint film will accumulate in the bearings, causing the bearing gap to be blocked. This will hinder the rotation of the bearings, increase the impurity content in the lubricating oil, and further aggravate the wear and failure of the equipment.

[0007] 4. Corrosion of equipment parts: Organic acids and other corrosive substances in the paint film will corrode equipment parts, causing damage to equipment parts and shortening their lifespan.

[0008] In order to reduce the harm of varnish, it is usually necessary to take two measures, adsorption and filtration, to remove varnish and other impurities in the lubricating oil.

[0009] Commonly used filtration methods include mechanical filtration, centrifugal filtration, electrostatic filtration, etc. These filtration methods can effectively remove paint and other impurities in lubricating oil, improve the quality and performance of lubricating oil, and extend the service life of equipment.

[0010] The commonly used adsorption method is to use specific adsorption paper to absorb pollutants such as paint film in the lubricating oil, gradually reduce the index of pollutants in the oil, and achieve the purpose of normal use.

[0011] In lubricating oil and insulating oil, soft pollutant paint films can have adverse effects on the normal operation of equipment. In order to remove these paint films, filter elements or adsorption units are required for filtration or adsorption. However, the technical indicators of filter elements or adsorption units on the market are not standardized, the rules are not unified, and the filter models are varied, which brings great difficulties to users' selection and use. Therefore, it is of great significance to develop a portable and universal adapter device for lubricating oil insulating paint film treatment filter elements or adsorption units.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] Reference Figure 1 A portable and universal paint film treatment device is connected in series in the oil circuit, does not require a built-in oil circuit, and uses the paint pressure difference for automatic filtering; the paint film treatment device specifically includes a filter 1, a filter cartridge 2, a filter plate 3, paint film adsorption particles 4, an oil inlet pipeline 5, a monitoring mechanism 6, a pre-filter 7, an oil inlet connector 8, an oil outlet connector 9, a drain pipeline 10, a drain valve 11, a lifting steam pump 12, a motor 13, an oil outlet pipeline 14, a lifting rod 15, a rotating rod 16 and a paint film filter paper 17.

[0044] Reference Figure 1 The filter 1 is a cylindrical structure as a whole, and its top is connected to the oil inlet pipeline 5, wherein the end of the oil inlet pipeline 5 penetrates from the top of the filter 1, and can introduce the paint into the filter cartridge 2 arranged inside the filter 1 for paint treatment. Removable covers are arranged above and below the filter 1 for subsequent removal of the filter cartridge 2 for cleaning and other work.

[0045] Reference Figure 3 The filter cartridge 2 is the core part of the device and is used to filter the paint film. The filter cartridge 2 can be removed from the inside of the filter 1 for easy replacement and maintenance. A filter plate 3 is provided inside the filter cartridge 2, and sieve holes are provided on the filter plate 3. A number of paint film adsorption particles 4 for filtering the paint film are provided in the filter cartridge 2. The specific number of paint film adsorption particles 4 to be used depends on the actual filtering requirements of the paint film, and is not limited in this application. The color of the paint film adsorption particles 4 after treatment will become heavier or black, and then the filter cartridge 2 is removed from the filter 1, and the internal paint film adsorption particles 4 are taken out for replacement.

[0046] It should be noted that the diameter of the sieve holes on the filter plate 3 needs to be smaller than the diameter of the paint film adsorption particles 4. Specifically, the diameter of the paint film adsorption particles 4 is 2 mm, and the diameter of the sieve holes is 1.5 mm.

[0047] Alternatively, the diameter of the paint film adsorption particles 4 is 2.2 mm, and the diameter of the sieve holes is 1.7 mm.

[0048] Furthermore, the paint film adsorption particles 4 can be made of FLUITEC resin material, which has high efficiency in filtering paint films and is harmless; specific FLUITEC resin adsorption technology: This technology uses special resins to selectively adsorb and absorb paint film precursors from the running oil based on their special chemical properties (slightly polar, similar to carboxylic acid). This technology can continuously remove dissolved paint film precursors from the running oil, reduce the concentration of paint film precursors, and maintain a low concentration of dissolved paint film precursors in the running oil without any effect on the healthy components of the lubrication.

[0049] Reference Figure 1 A motor 13 is provided below the filter 1 for driving the filter cartridge 2 to rotate and lift, and for preventing the internal sieve holes from being blocked. The output end of the motor 13 is connected to the filter cartridge 2 through the filter 1 via a rotating rod 16; when the paint film adsorption particles 4 purify the paint film inside the filter cartridge 2, in order to ensure that each paint film adsorption particle 4 can fully treat the paint film, the motor 13 can be controlled to work, and the motor 13 drives the filter cartridge 2 to rotate via the rotating rod 16, so that the paint film adsorption particles 4 perform centrifugal motion inside the filter cartridge 2, and because their diameter is larger than the diameter of the sieve holes on the filter cartridge 2, the paint film adsorption particles 4 will not be stuck in the sieve holes when rotating inside the filter cartridge 2, and the paint film adsorption particles 4 fully contact the paint film during this process, thereby achieving the effect of purifying the paint film.

[0050] The motor 13 of the present application can not only improve the purification efficiency when the paint film is rotating, but also can achieve the effect of cleaning the filter cartridge 2 in combination with a cleaning agent after the work is completed. Specifically, the cleaning agent can be poured into the inside of the filter cartridge 2, and then the motor 13 drives the filter cartridge 2 to rotate through the rotating rod 16. At this time, the cleaning agent performs centrifugal motion inside the filter cartridge 2, so that it fully contacts the inner wall of the filter cartridge 2, thereby achieving the effect of cleaning the filter cartridge 2.

[0051] In order to ensure that the paint film adsorbed particles 4 in the filter cartridge 2 are convenient to remove, the present application also provides a lifting steam pump 12 for driving the filter cartridge 2 to move upward under the filter 1. Two groups of lifting steam pumps 12 are provided, which are respectively located on both sides of the motor 13, wherein the output end of each lifting steam pump 12 is connected to a lifting rod 15, and the lifting rod 15 can pass through the filter 1 to push the filter cartridge 2 to move up and down. When the lifting steam pump 12 rises through the lifting rod 15 to contact the filter cartridge 2, and then continues to rise until the filter cartridge 2 is pushed out of the filter 1, the filter cartridge 2 can be replaced or the internal paint film adsorbed particles 4 can be replaced; it should be noted that the connection position of the rotating rod 16 of the motor 13 and the filter cartridge 2 is detachable and not fixed, so as to ensure that the upward movement of the filter cartridge 2 is not affected by the rotating rod 16 of the motor, and when the filter cartridge 2 moves down to be engaged with the rotating rod 16, the motor 13 can control the rotation of the filter cartridge 2; a corresponding sliding clamp can be provided on the inner wall of the filter 1 to make it slide in contact with the outer wall of the filter cartridge 2, and will not affect the rotation of the filter cartridge 2, thereby ensuring that the filter cartridge 2 does not rotate crooked.

[0052] Reference Figure 1 The filter 1 is connected to the oil inlet pipeline 5 at the top and the oil outlet pipeline 14 at the bottom;

[0053] In order to ensure that the present application can be connected to different types of oil filtering and processing equipment to provide universality, the present application sets an oil inlet joint 8 with an adjustable pipe diameter size at the interface of the oil inlet pipeline 5 of the filter 1 for connecting to the external oil circuit. Similarly, an oil outlet joint 9 with an adjustable pipe diameter size is set at the interface of the oil outlet pipeline 14 of the filter 1 for connecting to the external oil circuit. The oil inlet joint 8 has the same structure as the oil outlet joint 9. Ball valve 1 and ball valve 2 are respectively set on the oil inlet pipeline 5 and the oil outlet pipeline 14 and on one side of the corresponding universal joint to control the flow rate of oil inlet and oil outlet, wherein ball valve 1 and ball valve 2 are both connected to the industrial computer.

[0054] Furthermore, a pre-filter 7 and a monitoring mechanism 6 for monitoring the paint are provided on the oil inlet pipeline 5 and between the filter 1 and the oil inlet connector 8. The monitoring mechanism 6 includes a pressure probe, a flow probe and an oil temperature probe. The pressure probe, the flow probe and the oil temperature probe are all connected to the industrial computer. The pressure probe, the flow probe and the oil temperature probe are respectively used to detect the pressure, flow and oil temperature of the paint in the oil inlet pipeline 5, and transmit the monitored data to the industrial computer.

[0055] Reference Figure 1 A drainage pipe 10 is also connected to the bottom of the filter 1. The drainage pipe 10 is used to discharge the cleaning water after the filter cartridge 2 is cleaned. A drainage valve 11 is also provided on the drainage pipe 10. The drainage valve 11 can also be connected to the industrial computer; Figure 7 The motor 13 can also be connected to the industrial computer. The motor 13, ball valve 1, ball valve 2 and drain valve 11 are connected to the industrial computer through the IO relay. The pressure probe, flow probe and oil temperature probe are used to detect the pressure, flow and oil temperature of the paint in the oil inlet pipeline 5 respectively, and transmit the monitored data to the industrial computer, which can then be used to control the motor 13, ball valve 1, ball valve 2 and drain valve 11.

[0056] When in use, the oil inlet connector 8 and the oil outlet connector 9 of the present application are respectively connected to the existing paint oil circuit, without the need for external power. In this process, the paint film treatment can be performed on the oil circuit in use. First, the paint enters the oil inlet pipeline 5 through the oil inlet connector 8, is first pre-filtered by the pre-filter 7, and then enters the filter cartridge 2 in the filter 1 after passing through the pressure probe, flow probe and oil temperature probe. In this process, the pressure probe, flow probe and oil temperature probe are respectively used to detect the pressure, flow and oil temperature of the paint in the oil inlet pipeline 5, and the monitoring The measured data is transmitted to the industrial computer; then, under the action of the motor 13, the paint entering the filter cartridge 2 and a number of paint film adsorption particles 4 perform centrifugal motion in the filter cartridge 2. During this process, a number of paint film adsorption particles 4 fully treat the paint film, and the paint after the paint film treatment can flow out from the oil outlet pipeline 14. It should be noted that a valve can be set at the bottom of the filter cartridge 2, which can be controlled by the industrial computer. After opening, the paint can flow out and enter the oil outlet pipeline 14 and flow back into the paint oil circuit. The present application is reasonably designed, simple to operate, and convenient and lightweight.

[0057] Example 2

[0058] Reference Figure 4 and Figure 5 The rest is the same as above, and the difference from Example 1 is that in this embodiment, the paint film adsorption particles 4 are replaced with paint film filter paper 17, and a paint film filter paper 17 for filtering the paint film is provided in the filter cartridge 2 and at the rear side of the filter plate 3; or the filter plate 3 is placed horizontally, and the paint film filter paper 17 is placed under the filter plate 13, so that the paint first passes through the filter plate 3 and then enters the paint film filter paper 17 for filtration.

[0059] Example 3

[0060] Reference Figure 2 The rest is the same as above, and the difference from Example 1 is that in this embodiment, the paint film adsorption particles 4 and the paint film filter paper 17 are used simultaneously, and a paint film filter paper 17 for filtering the paint film is provided inside the filter cartridge 2 and at the rear side of the filter plate 3, and a number of paint film adsorption particles 14 are scattered inside the filter cartridge 2. When the filter cartridge 2 rotates, the paint film is filtered by the paint film by the number of paint film adsorption particles 4 and the paint film filter paper 17 simultaneously.
