Description

[Detailed Description of the Invention] [Technical Field 21 The present invention relates to a filter for filtering out solid substances in fuel oil, and the present invention relates to a filter for filtering out solid substances in fuel oil, in which the filtered solid substances are continuously filtered out on a patented filter surface. [Conventional technology and its problems] With the deterioration of the fuel situation, large diesel engines are forced to burn poor-quality oil, and this As a result, the fuel filter is inevitably contaminated with #IO before using inferior oil.
All Seki Miramicrons are made smaller by about 5 to 10 microns. 0 When unfavorable fuel is passed through a fine-sized sieve, the sieve will inevitably become clogged, and in extreme cases, 5~
Complete occlusion occurs within 10 minutes.

For this reason, it is a well-known fact that automatic cleaning techniques have already been introduced and put into practical use. , etc.

(B) requires the installation of a simple ultrasonic generator, which requires a large amount of capital investment.

(b) is the filter σ) secondary (It!l blows out 'I
Accumulation of solid matter due to accumulated fuel occurs on the primary side, and it is necessary to remove and dispose of it, and it is only possible to clean areas where fuel oil can easily pass through.

(c) Several filters are required for continuous operation since the fuel oil must be discharged once during cleaning.

[Objective of the Invention] The object of the present invention is to continuously and uniformly suck the solid matter filtered out onto the filter ml and to absorb the solid matter evenly over the entire surface of the filter. An object of the present invention is to provide a fuel oil filter that can be removed from the filter surface.

[Key points of the invention]

In order to achieve the above-mentioned object, the present invention provides a cylindrical filter for filtering out solid substances in fuel oil, and an opening in a wall surface arranged on a central axis of the filter. a hollow suction rod having a suction rod; and a box-shaped scraper extending from the suction rod so that its end surface contacts the filter surface and having a suction [1] on the end surface. As the suction rod rotates, the scraper rotates, scraping off the solid matter filtered onto the filter surface with its end face, and sucking the solid matter into the scraper from the suction port on the end face, and further scraping off the solid matter filtered onto the filter surface. [Example of the invention] Hereinafter, the present invention will be described. Fig. 1 shows an example of the fuel oil filter according to the present invention being used in a ship's fuel oil management system, and Fig. 2 shows an example of a scraper used in the filter according to the present invention. Give an example.

In FIG. 1, the present invention includes a cylindrical filter 1, a hollow suction rod 2 disposed on the central axis of the filter 1, and an end face 3 of the suction rod 2 in contact with +Ki of the filter 1. It is equipped with a scraper 4 formed in an elongated manner, and fuel oil such as C heavy oil is introduced in the direction of the arrow, filtered through the filter 1, and taken out from the outlet 116 in the direction of the arrow.

In the filter described in 11a, the filter 1/-=bar 4 is constructed as shown in FIG. That is, in FIG. 2, reference numeral 2 denotes a suction rod, which is rotatably mounted on the central axis of the cylindrical filter 1 shown in FIG. 8 is a hollow portion of the suction rod 2. The scraper 4 extends from the suction rod 2 so as to come in contact with the filter 1, and is formed into a box shape, and has a large number of suction ports 9, 9. ...9 is tilted,
The holes will be drilled in 1m rows. 10 is the inside of the box-shaped scraper 4 as in FIG.

In such a filter of the present invention, the suction rod 2 is rotated by the driving force (l) of the motor 1, and along with this rotation, the scraper 4 is rotated fL. As the solid matter is scraped off, the solid matter is sucked into the interior 10 of the scraper 4 through a number of suction ports 9, 9, . 2 507 into the hollow part 8, and is continuously removed by bending the discharge 1'' 14.

In such a filter of the present invention, the suction 1'' 9a or the end W2B
Filter 1
The solid matter filtered out on the filter is sucked continuously and evenly over the entire surface of the filter, so that the solid matter on the filter is completely removed.

11 is a casing, 12 is a cap. When the filter of the present invention is used for fuel oil backing/stem as shown in the first diagram, the solid matter discharged from tJF outlet 1/I bends the conduit and connects to the booster. By the suction force of the pump 10, it is introduced into the homogenizer 17 and pulverized. The pulverized solid material passes through the conduit 15 and passes through the pipe L provided in the cap 12.
118 is returned to the inside of the filter 19, where it is mixed with C heavy oil from population 5. 020 is a power source, 21,
22 are Ju-Yu, respectively.

In FIG. 1, the motors 13, 21, 22 are driven by the power supply 20 and respectively rotate the suction rod 2 and operate the booster pump Hi, as well as the homogenizer I7.
is also in operation.

In such a system as shown in FIG. 1, heavy oil C from the inlet 5 is filtered by the filter 1, guided from the outlet IJ 6 to the engine or storage tank (not shown), and filtered solid solids are deposited on the filter 1. The material is scraped off by the scraper 4, and the suction ports 9, 9. 9 is sucked into the scraper by the suction force of the booster pump 16, and further passed through the open lower and hollow part 8 to the discharge port 4 and is pulverized by the homogenizer 17, and then from person 1] 18 It is returned to the inside 19 of the filter. Since this operation is performed automatically and continuously, it is suitable as a fuel oil management system. In addition, in FIG. 1, 23. U is a pressure cutter, 5 is a pressure alarm, 26 is a pressure controller, and 27 is a valve.If the pressure in the system increases due to filter 1 clogging, etc., and a danger occurs, the pressure course will be changed. , 24 indicate this pressure and are alarmed by a pressure alarm, and further, the pressure controller 26 is actuated to open the valve 27 to guide the C heavy oil in the interior 19 of the filter to the conduit 5 through the line. Prevent danger.

〔Effect of the invention〕

As described above, in the filter of the present invention, the suction ports on the end face of the scraper are arranged in parallel at an angle, so that the solidified matter filtered onto the filter is continuously and evenly sucked over the entire surface of the filter. It can be completely removed from surfaces, making it particularly suitable as a filter for fuel oil management systems on ships, etc., making it an extremely useful invention for practical use.
