Description

TECHNICAL FIELD

[0001] The utility model belongs to filter technical field, specifically a kind of novel candle filter. BACKGROUND

[0002] Rapeseed oil is commonly known as vegetable oil, also known as rapeseed oil, canola oil, and mustard seed oil. It is a kind of edible oil extracted from rapeseed. During the production of rapeseed oil, solid-liquid separation is achieved by squeezing rapeseed. Impurities exist in the squeezed rapeseed oil, and therefore, filtration and separation of rapeseed oil are required.

[0003] During the filtration of rapeseed oil, a candle filter is usually used. Multiple filter elements are arranged in the cylinder of the filter. When rapeseed oil passes through the filter elements, the filtrate becomes clear, meeting the production requirements of rapeseed oil.

[0004] During the filtration of rapeseed oil, solid substances in the liquid gradually accumulate on the surface of the filter element. When these solid substances reach a certain thickness, a so-called "filter cake layer" is formed. Generally, air is blown into the filter element to blow off the "filter cake layer" through the filter holes on the filter element. However, when the "filter cake layer" is thick, this operation may not effectively clean the surface of the filter element. Therefore, a novel candle filter is proposed to solve the above problems. SUMMARY

[0005] To make up for the shortcomings of the prior art and solve at least one technical problem raised in the background, the utility model provides a novel candle filter.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] The specific embodiments are given below.

[0025] Please refer to Figures 1-4 The utility model provides a novel candle type filter, including rack 1 and setting on rack 1 filter cartridge 2, be provided with control panel on rack 1, and control panel and electric element in the device carry out electric connection, filter cartridge 2 is made of stainless steel material, improve filter cartridge 2 service life, the lower part of filter cartridge 2 is provided with electric control cover plate 3, and it is convenient to discharge and handle the " filter cake layer" that filter piece outside falls off, the lower part of filter cartridge 2 side is provided with oil inlet pipe 4, and it is convenient to carry out external connection and carry out the oil tank that filters, so that the rapeseed oil that is filtered is discharged to filter cartridge 2 in pressure, the inside of filter cartridge 2 is provided with candle type filter mechanism, and the impurity in the rapeseed oil is filtered, and candle type filter mechanism includes the multiple filter pieces that are evenly set in filter cartridge 2, and filter piece is made of stainless steel material, and the upper part of multiple filter pieces is provided with annular connecting pipe 5, and annular connecting pipe 5 is provided with shunt pipe 6, and the cleaning mechanism is set up on candle type filter mechanism, and the " filter cake layer" on the surface of filter core falls off, and the upper part of filter cartridge 2 is provided with cartridge cover 7, and cartridge cover 7 is provided with motor 8, and the output end of motor 8 is connected with cleaning mechanism, and the cleaning mechanism is driven.

[0026] Further, as shown in Figure 1 And Figure 3 The outer end of shunt pipe 6 is provided with two interfaces, the horizontal interface is oil outlet 9, and the vertical interface is air pipe 10. Electromagnetic valves are arranged on oil outlet 9 and air pipe 10. A tank for collecting filtered rapeseed oil is connected to oil outlet 9. Air source is connected to air pipe 10 to blow air into inner cavity pipe 11. The "filter cake layer" is blown off through the oil filter hole 13 on the outer cavity pipe 12.

[0027] Further, as shown inFigure 4 As shown, the filter element includes an inner cavity tube 11 connected to an annular connecting pipe 5, and an outer cavity tube 12 is provided outside the inner cavity tube 11. The lower part of the inner cavity tube 11 does not contact the outer cavity tube 12. Multiple oil filter holes 13 are evenly arranged on the side wall of the outer cavity tube 12. The inner cavity tube 11 and the outer cavity tube 12 are integrally formed. By pressurizing and supplying oil to the filter cylinder 2, the rapeseed oil on the outside of the filter element enters the interior of the outer cavity tube 12 through the oil filter holes 13 on the outer cavity tube 12, thereby extracting the filtered rapeseed oil through the inner cavity tube 11.

[0028] Furthermore, such as Figure 4 As shown, multiple support plates 14 are evenly arranged between the inner cavity tube 11 and the outer cavity tube 12. The support plates 14 are provided with through grooves 15 to improve the integrity of the filter element and thus improve the pressure resistance of the filter element.

[0029] Furthermore, such as Figure 2 As shown, the cleaning mechanism includes a rotating rod 16 connected to the output end of the motor 8. A support plate 17 is threaded onto the rotating rod 16. Multiple grooves 18 are evenly distributed on the support plate 17, and the multiple grooves 18 correspond to multiple filter elements. An annular scraper 19 is provided on the inner side of the groove 18. The corresponding annular scraper 19 is in contact with the outer cavity tube 12. The lower outer side of the annular scraper 19 is curved. Multiple blades 20 are evenly distributed around the bottom of the annular scraper 19 to remove and clean the "filter cake layer" on the surface of the filter element.

[0030] Furthermore, such as Figure 1 As shown, a pressure gauge 21 is installed on the cylinder cover 7 to monitor the pressure inside the filter cylinder.

[0031] Working principle: When filtering the squeezed rapeseed oil, the oil inlet pipe 4 below the filter cylinder 2 is connected to the oil tank to be filtered, and the oil outlet 9 is connected to the tank for collecting the filtered rapeseed oil. An external air source is connected to the air pipe 10 to pressurize and discharge the rapeseed oil to be filtered into the filter cylinder 2.

[0032] The rapeseed oil is filtered through the structure of the candle filter mechanism. During operation, the solenoid valve on the oil outlet 9 is opened and the solenoid valve on the air pipe 10 is closed, so that the rapeseed oil is continuously poured into the filter cylinder 2. The rapeseed oil is pressurized and passes through the filter holes on the outer cavity tube 12, flows down from the outer cavity tube 12 to the bottom, and then passes up through the inner cavity tube 11 to the annular connecting pipe, and is discharged from the oil outlet 9 of the diversion tube 6.

[0033] The filtered rapeseed oil impurities accumulate to a certain thickness on the filter element surface, forming a "filter cake layer." When cleaning the "filter cake layer," the solenoid valve on the oil drain port 9 is closed, and the solenoid valve on the air pipe port 10 is opened. The gas forces the rapeseed oil in the filter into the external oil tank. Then, the gas continues to be discharged, blowing air into the inner cavity pipe 11. Through the oil filter holes 13 on the outer cavity pipe 12, the "filter cake layer" is back-blown off. Combined with the structural design of the cleaning mechanism, the "filter cake layer" on the filter element surface is cleaned. The filter cake layer is effectively cleaned by the operation of motor 8, which causes the rotating rod 16 to rotate. At this time, the support plate 17 moves on the rotating rod 16, and the annular scraper 19 on the plate groove 18 moves on the outer cavity tube 12. The lower outer side of the annular scraper 19 is curved, which continuously pushes the filter cake layer outward. The multiple blades 20 at the bottom of the annular scraper 19 can break through the thicker filter cake layer, so that the filter cake layer can be removed. Then, the control 2 electrically controlled cover 3 opens to discharge impurities.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
