Filtering device for royal jelly processing

Abstract

The utility model provides a filtering device for royal jelly processing, which solves the problems that the continuously added royal jelly applies pressure to a filter screen to cause local elastic deformation of the filter screen, so that a gap between a concave area of the filter screen and a scraper blade is increased, the scraping and sweeping effect of partial area is invalid, filter residues cannot be effectively scraped off to block the filter screen, and the service life of the filter screen is prolonged. The filtering efficiency of the royal jelly is influenced. The corrugated pipe coupling is arranged between the output shaft of the driving motor used for driving the arc-shaped scraping plate and the driving shaft, and the corrugated pipe coupling is pre-compressed during initial installation, so that the arc-shaped scraping plate is pressed to abut against the first filter screen, and when the first filter screen is concave downwards, the corrugated pipe coupling axially stretches out and draws back to compensate displacement; the arc-shaped scraping plate is always attached to the surface of the first filter screen, the situation that a gap between the concave area of the first filter screen and the arc-shaped scraping plate is increased, consequently, the scraping and sweeping effect of part of the area is invalid is avoided, and therefore the situation that filter residues cannot be effectively scraped, the first filter screen is blocked, and the royal jelly filtering efficiency is affected is avoided.

Description

Technical Field

[0001] This utility model relates to the field of royal jelly processing technology, and in particular to a filtration device for royal jelly processing. Background Technology

[0002] Royal jelly is a secretion from the pharyngeal glands of young worker bees that raise larvae in the hive. It is the food that supplies larvae that will become queen bees and is also the queen bee's lifelong food. It has high nutritional value. During the processing of royal jelly, a filtration device is needed to remove impurities such as beeswax and larval residue.

[0003] Existing filtration devices typically employ flat scrapers with fixed gaps. For example, Chinese Utility Model Patent Publication No. 202120672237.X discloses a royal jelly production device. This device features a rotating scraping assembly inside the coarse and fine filtration tank, using scrapers to remove impurities from the filter screen. This patent uses a rigid shaft system to connect the flat scraper, a design based on the assumption of an absolutely flat filter screen. However, in actual operation, the continuously added royal jelly applies pressure to the filter screen, causing localized elastic deformation. The rigid connection between the drive shaft and the scraper cannot compensate for the increased gap between the filter screen and the scraper caused by the elastic deformation. This results in the scraping action failing in some areas, preventing the effective removal of filter residue and clogging the filter screen, thus affecting the filtration efficiency of the royal jelly. Utility Model Content

[0004] To address the problem in the prior art where the continuous addition of royal jelly exerts pressure on the filter screen, causing localized elastic deformation, which leads to an increase in the gap between the concave area of ​​the filter screen and the scraper, resulting in the failure of the scraping action in some areas, the inability to effectively remove filter residue, and thus clogging the filter screen and affecting the filtration efficiency of royal jelly, this utility model proposes a filtration device for royal jelly processing.

[0005] The technical solution of this utility model is: a filtration device for processing royal jelly, including a filter tank, the upper half of which is a tubular structure that is open from top to bottom, the lower half of which is a conical structure with a horizontal diameter that gradually decreases from top to bottom, and a discharge pipe that is fixedly connected to and connected to the bottom end of the filter tank.

[0006] Multiple downward-extending support legs are fixedly provided on the outer circumference of the filter tank. A U-shaped frame facing downwards is fixedly provided at the top of the filter tank. A drive motor is fixedly provided above the top of the U-shaped frame. The output shaft of the drive motor passes through the U-shaped frame and is fixedly provided with a drive shaft. An arc-shaped scraper is fixedly provided at the bottom of the drive shaft along the radial direction of the filter tank. A first filter screen is provided horizontally inside the filter tank. The arc-shaped scraper abuts against the upper surface of the first filter screen. A bellows coupling is provided between the output shaft of the drive motor and the drive shaft.

[0007] Preferably, the bellows coupling includes two half-couplings spaced apart vertically and a metal bellows fixed in the middle. The output shaft of the drive motor passes through the upper half-coupling, and the top end of the drive shaft passes through the lower half-coupling.

[0008] Each half-coupling has two threaded holes arranged radially. The two threaded holes are arranged perpendicularly to each other in the horizontal direction. A screw is threaded through the threaded hole, and the end of the screw passes through the threaded hole and abuts against the output shaft or drive shaft of the drive motor.

[0009] Preferably, the filter tank is provided with a sleeve that is open at both ends and can move up and down. The first filter screen is fixed at the bottom of the sleeve, and the top of the sleeve passes through the filter tank and is fixed with a lifting ring that extends horizontally outward. The lifting ring presses against the filter tank.

[0010] Preferably, a limiting ring is fixedly provided at the bottom of the upper half of the filter tank, and a second filter screen is provided at the top of the limiting ring, the mesh size of the second filter screen being smaller than that of the first filter screen.

[0011] Preferably, a vibration motor is fixedly installed on the lower half of the outer wall of the filter tank.

[0012] Preferably, a spring support is provided between the top of the support leg and the filter tank. The spring support includes a fixed base fixed to the filter tank and a high-stiffness spring fixed to its bottom. The bottom end of the high-stiffness spring is fixed to the top of the support leg.

[0013] Advantages of this invention: This invention uses a bellows coupling between the output shaft of the drive motor that drives the arc-shaped scraper and the drive shaft. During initial installation, the bellows coupling is pre-compressed, causing the arc-shaped scraper to press against the first filter screen. As the first filter screen is recessed, the bellows coupling axially expands and contracts to compensate for the displacement, ensuring that the arc-shaped scraper always stays in contact with the surface of the first filter screen. This prevents the gap between the recessed area of ​​the first filter screen and the arc-shaped scraper from increasing, which could lead to the failure of the scraping action in some areas. This avoids the filter residue from being unable to be effectively scraped away, thus preventing blockage of the first filter screen and affecting the filtration efficiency of royal jelly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A filtration device for royal jelly processing, such as Figure 1-5 As shown, the filter includes a filter tank 1. The upper half of the filter tank 1 is a tubular structure that is open from top to bottom, and the lower half of the filter tank 1 is a conical structure with a gradually decreasing horizontal diameter from top to bottom, so as to concentrate the filtered royal jelly. The bottom end of the filter tank 1 is fixedly connected to and connected to a discharge pipe 2, which is used to discharge the royal jelly concentrated at the bottom of the filter tank 1.

[0023] Multiple downward-extending support legs 3 are fixedly provided on the outer circumferential surface of the filter tank 1. A U-shaped frame 4 facing downward is fixedly provided at the top of the filter tank 1. A drive motor 5 is fixedly provided above the top of the U-shaped frame 4. The output shaft of the drive motor 5 passes through the U-shaped frame 4 and is fixedly provided with a drive shaft 6. An arc-shaped scraper 7 is fixedly provided at the bottom of the drive shaft 6 along the radial direction of the filter tank 1. The bottom of the arc-shaped scraper 7 is arc-shaped. A first filter screen 8 is provided horizontally inside the filter tank 1. The arc-shaped scraper 7 abuts against the upper surface of the first filter screen 8.

[0024] A bellows coupling 9 is provided between the output shaft of the drive motor 5 and the drive shaft 6. The bellows coupling 9 has high elasticity in the vertical direction. During initial installation, the bellows coupling 9 is pre-compressed so that the arc-shaped scraper 7 presses against the first filter screen 8. When the first filter screen 8 is concave, the bellows coupling 9 expands and contracts axially to compensate for the displacement, so that the arc-shaped scraper 7 always stays in contact with the surface of the first filter screen 8. This avoids the gap between the concave area of ​​the first filter screen 8 and the arc-shaped scraper 7 from increasing, which would cause the scraping effect in some areas to fail. This prevents the filter residue from being effectively scraped away and clogging the first filter screen 8, thus affecting the filtration efficiency of royal jelly.

[0025] The bellows coupling 9 includes two half-couplings 901 spaced apart vertically and a metal bellows 902 fixed in the middle. The output shaft of the drive motor 5 passes through the upper half-coupling 901, and the top end of the drive shaft 6 passes through the lower half-coupling 901. Each half-coupling 901 has two threaded holes arranged radially thereon. The two threaded holes are perpendicular to each other in the horizontal direction. A screw 903 is threaded through the threaded hole. The end of the screw 903 passes through the threaded hole and abuts against the output shaft of the drive motor 5 or the drive shaft 6 to fix the output shaft of the drive motor 5 and the drive shaft 6 in the same axial direction. By loosening the lower screw 903, the drive shaft 6 can be adjusted up and down in the axial direction to pre-compress the bellows coupling 9. At the same time, the height of the arc scraper 7 can be adjusted up and down according to the installation position of the first filter screen 8.

[0026] The filter tank 1 is equipped with a sleeve 10 that is open at both ends and can move up and down. The first filter screen 8 is fixedly installed at the bottom of the sleeve 10. The top end of the sleeve 10 passes through the filter tank 1 and is fixedly provided with a lifting ring 11 that extends horizontally outward. The lifting ring 11 presses against the filter tank 1 to restrict and fix the position of the sleeve 10 and the first filter screen 8. At the same time, it is convenient to remove the sleeve 10 with the first filter screen 8 from the filter tank 1, so as to facilitate the cleaning of the first filter screen 8 after filtering royal jelly for a long time.

[0027] A limiting ring 12 is fixedly provided at the bottom of the upper half of the filter tank 1. A second filter screen 13 is provided at the top of the limiting ring 12. The mesh size of the second filter screen 13 is smaller than that of the first filter screen 8, so as to perform fine filtration on the royal jelly after the initial filtration. No additional equipment is needed for fine filtration, which further improves the overall filtration efficiency. The second filter screen 13 has less filter residue to filter, so no cleaning mechanism is needed. A fixing ring is provided at the edge of the second filter screen 13 to fix the second filter screen 13, so as to facilitate the removal of the second filter screen 13 for cleaning.

[0028] A vibration motor 14 is fixedly installed on the lower half of the outer wall of the filter tank 1. The vibration motor 14 uses the centrifugal force generated by the high-speed rotation of the shaft and eccentric block to generate the excitation force, thereby driving the filter tank 1 to vibrate, improving the efficiency of royal jelly passing through the first filter screen 8 and the second filter screen 13, thereby improving the filtration efficiency, and at the same time avoiding clogging during the royal jelly filtration process.

[0029] A spring support 15 is provided between the top of the support leg 3 and the filter tank 1. The spring support 15 includes a fixed base 151 fixed on the filter tank 1 and a high-stiffness spring 152 fixed at its bottom. The bottom end of the high-stiffness spring 152 is fixed at the top of the support leg 3. The spring support 15 can increase the overall vibration amplitude of the filter tank 1, further improve the vibration effect generated by the vibration motor 14, and thus further improve the filtration efficiency, while reducing the vibration amplitude of the support leg 3.

[0030] Working principle: When the drive shaft 6 with the arc-shaped scraper 7 is installed on the bellows coupling 9, the bellows coupling 9 is pre-compressed so that the arc-shaped scraper 7 abuts against the first filter screen 8. Then, the screw 903 is tightened to fix the drive shaft 6. During the filtration process, royal jelly is continuously added into the sleeve 10 of the filter tank 1. When the filter screen is partially concave due to the pressure of the royal jelly, the bellows coupling 9 extends axially to compensate for the displacement, ensuring that the arc-shaped scraper 7 is fully in contact with the first filter screen 8. At the same time, the royal jelly intercepts the filter residue through the first filter screen 8. Then, the initial royal jelly filtrate falls to the second filter screen 13, which traps tiny wax particles. The royal jelly that has undergone two stages of filtration is then discharged through the discharge pipe 2.

[0031] During maintenance, lift the lifting ring 11 of the sleeve 10 to remove the first filter screen 8 for cleaning at once, and then remove the second filter screen 13 upwards for cleaning.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
