Description

Technical Field

[0001] The present application relates to the field of cosmetic production equipment, and in particular to a production raw material filtering structure. Background Art

[0002] Cosmetics are preparations (except soap) used on the human body to beautify, preserve or change one's appearance (for example, for performance), or preparations used to clean, dye, wipe, correct or protect the skin, hair, nails, eyes or teeth. At present, in the production of cosmetics, an indispensable process is to filter the cosmetics and raw materials. The quality of the filtration process directly affects the purity and product quality of the cosmetics.

[0003] For example, a cosmetic raw material filtering device disclosed in publication number CN214597603U has the following deficiencies in actual use:

[0004] When the above device filters the raw materials, the scraping device is tilted, which will cause a shielding effect and cause the raw materials to enter the filter residue collection box, resulting in waste of raw materials. At the same time, the above device uses a rectangular filter plate scraping device, which limits the cleaning area of ​​the filter screen and reduces the cleaning effect of the filter screen. Utility Model Content

[0005] In order to improve the problem of low cleaning effect of the filter screen, the present application provides a production raw material filtering structure.

[0006] A production raw material filtering structure provided in this application adopts the following technical solution:

[0007] A production raw material filtering structure comprises a barrel body and a cover plate detachably fixed to the upper end of the barrel body, wherein a filter screen for filtering is fixed in the middle of the inner cavity of the barrel body;

[0008] The scraping mechanism includes a scraping frame abutting against the upper end of the filter screen, guide slopes are provided on the opposite sides of both ends of the scraping frame, and accommodating grooves for storing impurities are provided at both ends of the scraping frame. Rubber wheels are rotatably provided at both ends of the scraping frame, and the two rubber wheels roll on the upper end of the fixed circular frame of the filter screen.

[0009] By adopting the above technical solution, the setting of the guide slope can make the impurities on the filter screen fall into the accommodating groove, which has the effect of cutting and scraping, making it easier to clean the filter screen.

[0010] Preferably, the scraping mechanism further comprises an auger rotatably arranged in a receiving groove inside the scraping frame, and a rotating shaft in the middle of the auger movably penetrates the scraping frame and is fixed to the rubber wheel;

[0011] A space for storing impurities is reserved between an end of the auger away from the rubber wheel and the inner wall of the accommodating groove.

[0012] By adopting the above technical solution, the friction between the rubber wheel and the filter screen is large, so the auger can be driven to rotate and the impurities inside the receiving tank are gathered to one end.

[0013] Preferably, a transmission shaft is fixed to the middle of the upper end of the scraping frame, and the transmission shaft is located at the upper end of the scraping mechanism and is fixed with a cone box for collecting impurities. The two accommodating grooves are located in the end space on one side of the auger and are provided with a conduit fixedly passing through the scraping frame.

[0014] By adopting the above technical solution, the cone box can collect impurities and then clean them uniformly. At the same time, a pipe can be inserted into the bottom of the cone box to use an external extraction device to extract impurities inside the cone box, eliminating the step of replacing the cone box.

[0015] Preferably, the upper ends of the two conduits movably penetrate the two sides of the lower end of the cone box and are clamped and limited, and the outer diameters of the two conduits at the ends of the inner cavity of the cone box are smaller than the outer diameters of the lower ends of the conduits.

[0016] By adopting the above technical solution, the cone box is fixed to the conduit by clamping, so that the cone box is easy to install and disassemble.

[0017] Preferably, a negative pressure pump is fixed to the top of the inner cavity of the cone box, the air suction port of the negative pressure pump is located inside the cone box, and the discharge end of the negative pressure pump is fixed with an exhaust elbow penetrating the upper end of the fixed cone box.

[0018] By adopting the above technical solution, the provision of the negative pressure pump can enable the catheter to draw the impurities inside the receiving groove into the cone box for collection to facilitate later cleaning.

[0019] Preferably, a motor is fixedly provided in the middle of the upper end of the cover plate, and the output shaft of the motor movably passes through the cover plate and is fixedly connected to the upper end of the transmission shaft.

[0020] By adopting the above technical solution, the motor can provide a rotational driving force to the scraping frame.

[0021] Preferably, a current collecting slip ring fixed to the cone box is sleeved on the upper end of the transmission shaft, and the fixed end of the current collecting slip ring is fixed to the lower end of the cover plate.

[0022] By adopting the above technical solution, the collector slip ring can ensure that the negative pressure pump can be powered on and work normally when it rotates.

[0023] Preferably, the axis of the transmission shaft coincides with the central axis of the filter screen.

[0024] By adopting the above technical solution, the coincidence of the central axis can avoid the deviation of the scraping frame during rotation and cause interference with the inner wall of the barrel.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Use the scraping mechanism to scrape and clean the impurities on the upper end of the filter. The scraping frame covers the filtering surface of the filter to improve the cleaning effect and also improve the filtering effect of the filter;

[0027] 2. With the help of the negative pressure pump and the cone box, the collected impurities can be stored centrally, so that the scraping mechanism can work continuously and improve the cleaning effect of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1 —5 further describes this application in detail.

[0037] The embodiment of the present application discloses a production raw material filtering structure.

[0038] Example 1

[0039] Reference Figure 1A production raw material filtering structure comprises a barrel body 1 and a cover plate 2 fixed to the upper end of the barrel body 1 by bolts, a feed pipe connected to the inner cavity of the barrel body 1 and used for feeding is provided on one side of the upper end of the cover plate 2, a discharge pipe connected to the inner cavity of the barrel body 1 and used for discharging is fixed at the bottom of the barrel body 1, a valve body for controlling the on-off of the discharge pipe is provided on the surface of the discharge pipe, a plurality of fixing feet are fixed at the lower end of the barrel body 1, the middle part of the upper end of the cover plate 2 is fixed to the mounting end of the motor 3 by bolts, the output shaft of the motor 3 movably passes through the cover plate 2, and the end of the output shaft of the motor 3 is detachably connected to the upper end of the transmission shaft 8 by threads The central axis of the transmission shaft 8 coincides with the central axis of the filter screen 4, so that the scraping frame 51 rotates more smoothly. A collector slip ring 10 is fixed on the upper end of the transmission shaft 8. The rotating end of the collector slip ring 10 is fixed to the upper end of the cone box 6 by screws. The fixed end of the collector slip ring 10 is fixed to the lower end of the cover plate 2. The connecting wire of the fixed end of the collector slip ring 10 passes through the cover plate 2 and is connected to the external power supply. The wire of the movable end of the collector slip ring 10 is fixed to the wiring segment of the negative pressure pump 7. The middle part of the inner cavity of the barrel body 1 is fixed to the outer mounting frame of the filter screen 4. The filter screen 4 is used to filter the raw materials.

[0040] Through the above-mentioned arrangement, the feed pipe can be connected to the pipeline of the external raw material supply device, thereby realizing real-time pipeline raw material transportation. At the same time, the motor 3 is energized to work, and the output shaft of the motor 3 will drive the cone box 6 and the scraping mechanism 5 to rotate, thereby scraping and collecting the impurities on the upper end of the filter screen 4. The collected impurities will eventually enter the inside of the cone box 6 for storage and unified dumping later. At the same time, the filter screen 4 can filter the raw materials. The solid matter remains at the upper end of the filter screen 4, and the liquid flows to the bottom of the barrel 1 and is discharged from the discharge pipe, so that the filtered raw materials enter the next process.

[0041] Reference Figure 2-4The scraping mechanism 5 includes a scraping frame 51 abutting against the upper end of the filter screen 4. The scraping frame 51 can slide on the upper end surface of the filter screen 4. The two ends of the scraping frame 51 are provided with inclined guide slopes 53 on the opposite sides. One end of the guide slope 53 extends to the contact surface of the scraping frame 51 and the filter screen 4, so that solid impurities can enter the receiving groove 55 along the guide slope 53 to achieve scraping and collection. The two ends of the scraping frame 51 are provided with semicircular receiving grooves 55 for storing impurities. The two receiving grooves 55 are not connected to each other. The scraping mechanism 5 also includes a rotating device set on The scraper frame 51 has an auger 52 in the internal accommodating groove 55, and the shape of the auger 52 matches the semicircular shape of the lower end of the accommodating groove 55. The rotating shaft in the middle of the auger 52 movably passes through the scraper frame 51, and the end of the rotating shaft in the middle of the auger 52 is fixed to the middle of the rubber wheel 54. The two rubber wheels 54 roll on the upper end of the fixed circular frame of the filter screen 4. The rubber wheel 54 is elastic and can be deformed under force to increase the friction with the fixed circular frame of the filter screen 4. A space for storing impurities is left between one end of the auger 52 away from the rubber wheel 54 and one end of the inner wall of the accommodating groove 55 away from the rubber wheel 54.

[0042] Through the above arrangement, when the scraper frame 51 rotates on the upper end of the filter screen 4, the impurities on the upper end of the filter screen 4 will accumulate on the surface of the guide slope 53. As the impurities accumulate too much, the impurities will be pushed to move on the guide slope 53 and fall into the receiving groove 55. At this time, the two rubber wheels 54 rotate on the circular frame of the filter screen 4 and then drive the two augers 52 to rotate through the rotating shaft. The two augers 52 rotate to push the impurities to move into the receiving groove 55 in the direction of the transmission shaft 8 and accumulate, thereby achieving the collection effect.

[0043] Reference Figure 2 The middle part of the upper end of the scraping frame 51 is fixed to the lower end of the circular transmission shaft 8, and the longitudinal axis of the middle part of the upper end of the scraping frame 51 coincides with the longitudinal axis of the transmission shaft 8. The transmission shaft 8 is located at the upper end of the scraping mechanism 5 and is interspersed with a cone box 6 fixed therethrough. The upper end of the cone box 6 is arranged as an inclined surface to prevent the raw materials from accumulating at the upper end of the cone box 6 when entering, and the cone box 6 is used to collect impurities. Two receiving grooves 55 are arranged in the end space on one side of the auger 52, and a conduit 9 is arranged therein. The middle part of the conduit 9 is fixedly passed through the side wall of the scraping frame 51, and the lower end of the conduit 9 is located at the bottom of the receiving groove 55 and leaves a gap for absorbing impurities. The upper end of the conduit 9 extends upward to a certain distance in the inner cavity of the cone box 6 to prevent impurities from re-entering the receiving groove 55 through the conduit 9.

[0044] Through the above arrangement, the output shaft of the motor 3 drives the transmission shaft 8 to rotate and then drives the cone box 6 and the scraper frame 51 to rotate. At the same time, the impurities accumulated inside the accommodating groove 55 are sucked by the conduit 9 and discharged into the interior of the cone 6 for collection. However, after the filtering device structure works, the user can remove the cone box 6 for collection.

[0045] Reference Figure 2 , 5 The upper ends of the two catheters 9 movably penetrate the two sides of the lower end of the cone box 6. The lower end of the cone box 6 is provided with two insertion holes corresponding to the catheters 9. The diameter of the insertion holes is smaller than the diameter of the middle part of the catheter 9, so that the cone box 6 can be fixed on the upper part of the catheter 9 when inserted. The outer diameter of the two catheters 9 at the ends of the inner cavity of the cone box 6 is smaller than the outer diameter of the lower end of the catheter 9. The smaller diameter of the upper end of the catheter 9 is convenient for insertion into the insertion hole of the cone box 6.

[0046] Through the above arrangement, when the inside of the cone box 6 is full, the user only needs to disassemble the cover plate 2 and the barrel body 1, and then unscrew the upper end threads of the output shaft of the motor 3 and the transmission shaft 8 for disassembly. After that, the user can pull the cone box 6 upward from the surface of the transmission shaft 8 to take out the cone box 6, and reinstall the new cone box 6.

[0047] It should be noted that an internal thread is provided at the upper end of the transmission shaft 8, and an external thread is provided on the end surface of the output shaft of the motor 3 to achieve threaded fixation. At the same time, when the motor 3 drives the transmission shaft 8 to rotate, the connection between the transmission shaft 8 and the output shaft of the motor 3 will be tightened.

[0048] Reference Figure 2 , 3 The top of the inner cavity of the cone box 6 is fixed to the fixed end of the negative pressure pump 7 by bolts. The air suction port of the negative pressure pump 7 is located at the upper part of the inner cavity of the cone box 6, and the discharge end of the negative pressure pump 7 is fixed with an exhaust elbow 11. One end of the exhaust elbow 11 penetrates and is fixed to the upper end of the cone box 6, and the air inlet end faces downward (such as Figure 3 shown).

[0049] Through the above arrangement, the negative pressure pump 7 is powered on and works, and the negative pressure pump 7 draws out the air inside the conical box 6 to realize a negative pressure state, and then absorbs the air inside the barrel body 1 through the conduit 9, and then sucks the impurities inside the receiving groove 55 into the conical box 6 through the conduit 9 for accumulation, and the negative pressure pump 7 discharges the air back into the barrel body 1 to realize circulation.

[0050] The implementation principle of a production raw material filtering structure in the embodiment of the present application is:

[0051] After the device is installed at the designated position, the raw material enters the barrel 1 through the feed pipe and is filtered through the filter screen 4. At the same time, the motor 3 drives the transmission shaft 8 to rotate, thereby driving the scraping frame 51 to rotate, and the rubber wheel 54 drives the auger 52 to rotate, and the auger 52 collects the impurities inside the receiving groove 55 to one end;

[0052] Subsequently, the collector slip ring 10 supplies power to the negative pressure pump 7, which reduces the air pressure in the cone box 6, thereby allowing the conduit 9 to absorb the impurities accumulated inside the receiving groove 55 and transfer the impurities inside the receiving groove 55 to the cone box 6, so that the scraping frame 51 can continuously scrape the impurities on the upper end of the filter screen 4.

[0053] In summary, the scraping frame 51 provided in the device can cover and scrape the filter screen 4 in all directions, effectively increasing the cleaning area of ​​the filter screen 4, improving the filtering effect of the filter screen 4, and not causing waste of raw materials.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
