Technical Field

[0001] This utility model relates to the field of confectionery processing, specifically a filtration device. Background Technology

[0002] In confectionery production, raw liquids (such as syrup) need to be filtered to remove undissolved particles, foreign matter, or caramelized impurities.

[0003] Chinese Patent Application No. CN202122181078.6 discloses a rotary candy raw material filtration device. A top plate is fixedly connected to the top of the filter cylinder, and a bottom plate is fixedly connected to the bottom of the filter cylinder. A vertical pipe is connected to the top of the top plate, and the top end of the vertical pipe penetrates the housing and extends to the top of the housing. A motor is fixedly connected to one side of the top of the housing, and bevel gears are fixedly connected to the output end of the motor and the surface of the vertical pipe. An annular plate is provided on the surface of the filter cylinder, and horizontal bars are fixedly connected to both sides of the annular plate. A fixing plate is fixedly connected to one end of each horizontal bar, and sliding plates are fixedly connected to both sides of the inner wall of the housing. A vertical bar is fixedly connected to the top of the fixing plate, and the top end of the vertical bar penetrates the housing and extends to the top of the housing. This rotary filtration method, under the action of centrifugal force, allows the candy raw materials to be filtered while in motion, preventing them from accumulating and improving the filtration effect.

[0004] However, most existing filter devices for candy processing suffer from filter mesh clogging during use. Most filter devices cannot detect clogging in time and often require observation of the clogging situation before taking action. Therefore, a new filter device is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, most existing candy processing filtration devices experience filter mesh clogging during use. Furthermore, most filtration devices require observation of the clogging situation before taking timely action, resulting in insufficient timeliness. This invention proposes a new filtration device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a filtration device, including a filter cylinder; a heating component is connected to the outside of the filter cylinder, a first filter component is connected to the inside of the filter cylinder, and a second filter component is connected to the lower end of the filter cylinder.

[0007] The filter assembly includes a cover plate threaded to the upper end of the filter cylinder. A drive motor is fixedly connected to the upper end of the cover plate, and a drive shaft is fixedly connected to the output end of the drive motor. Spiral guide vanes are fixedly connected to the outside of the drive shaft, and a sleeve is installed at the lower end of the drive shaft. Flanges are fixedly connected to the outside of both the sleeve and the drive shaft. The upper and lower flanges are detachably connected by locking bolts. A limit plate is slidably connected to the sleeve, and a locking block is fixedly connected to the outside of the limit plate. A groove adapted to the locking block is formed on the inner wall of the sleeve. The filter cylinder is slidably engaged with the slide groove. A spring is fixedly connected to the upper end of the limiting plate, and the other end of the spring is fixedly connected to the sleeve. A movable rod is fixedly connected to the lower end of the limiting plate. The movable rod passes through the sleeve and is slidably connected to the sleeve. Multiple scrapers are fixedly connected to the outside of the movable rod. The scrapers slide against the outer wall of the sleeve. Multiple positioning plates are fixedly connected to the inner wall of the filter cylinder. Positioning posts are fixedly connected to the upper ends of the multiple positioning plates. The external part of the drive shaft is movably disposed on the filter screen. A central hole is opened in the center of the filter screen. Multiple positioning grooves are opened at the lower end of the filter screen.

[0008] By setting up filter component one, in the initial state, the upper end of the scraper is tightly attached to the lower surface of the filter screen. When candy ingredients such as syrup enter the filter cylinder for filtration, the syrup flows forward, and the scraper moves downward under fluid pressure. By selecting a suitable spring, the scraper stretches after being pressed, maintaining a small gap between the scraper and the filter screen, so as not to affect the normal filtration effect of the filter screen. When blockage occurs, the pressure on the scraper decreases, the spring rebounds, and the scraper is driven upward to reset, allowing the scraper to adhere to the filter screen. The drive motor drives the transmission shaft to rotate, ultimately rotating the scraper to scrape away the blockage in the filter screen from all directions. This method can handle blockages without penetrating the filter screen, and can react immediately and deal with blockages in a timely manner.

[0009] Preferably, the outer surface of the movable rod is coated with an anti-stick coating, the diameters of the drive shaft and flange are both smaller than the diameter of the central hole, the drive shaft and flange both penetrate the central hole, and the diameter of the sleeve is larger than the diameter of the central hole.

[0010] By coating the outer surface of the movable rod with an anti-stick coating, such as a Teflon coating, the syrup will not stick to the surface of the movable rod when it moves up and down, thus preventing the syrup from being carried into the sleeve.

[0011] Preferably, the positioning post is movably inserted into the inside of the positioning groove, and the positioning post is adapted to the positioning groove.

[0012] Preferably, the drive shaft is rotatably connected to the cover plate, and the locking bolt is threadedly connected to the flange.

[0013] Preferably, the upper end of the cover plate is fixedly connected to a feed pipe, and the upper end of the feed pipe is threadedly connected to a sealing cap.

[0014] Preferably, the second filter assembly includes a discharge pipe, which is fixedly connected to the lower end of the filter cylinder. A filter is connected to the lower end of the discharge pipe. Both the filter and the discharge pipe are fixedly connected to a flange. The upper and lower flanges are detachably connected by a locking bolt, which is threaded to the flange.

[0015] Preferably, the inner wall of the filter is threaded with a permanent magnet grid, the upper end of the permanent magnet grid is connected to a handle, the lower end of the filter is fixedly connected to a connecting pipe, and the outer pipe of the connecting pipe is connected to a discharge valve.

[0016] Preferably, the heating assembly includes a heating jacket, which is fixedly connected to the outside of the filter cartridge. An electric heating plate is fixedly connected inside the heating jacket. A temperature sensor is fixedly embedded in the inner wall of the heating jacket, and a temperature controller is fixedly connected to the front end of the heating jacket.

[0017] The advantages of this utility model are:

[0018] 1. This utility model, by setting up a filter component, initially places the upper end of the scraper tightly against the lower surface of the filter screen. When candy ingredients such as syrup enter the filter cylinder for filtration, the syrup flows forward, and the scraper moves downward under fluid pressure. By selecting a suitable spring, the scraper stretches after being pressed, maintaining a small gap between the scraper and the filter screen, thus not affecting the normal filtration effect of the filter screen. When blockage occurs, the pressure on the scraper decreases, the spring rebounds, and the scraper returns upward, allowing the scraper to adhere to the filter screen. The drive motor drives the transmission shaft to rotate, ultimately rotating the scraper to scrape away the blockage in the filter screen from all directions. This method does not require penetrating the filter screen to remove blockages and can react immediately when blockage occurs, promptly addressing the blockage. In addition, the transmission shaft drives the spiral guide plate to rotate, which forces the syrup to pass through the filter screen in a vortex form, preventing local crystallization of the syrup on the filter screen surface and evenly dispersing the fluid pressure.

[0019] 2. This utility model coats the outer surface of the movable rod with an anti-stick coating, which can be a Teflon coating, so that the surface of the movable rod will not stick to syrup when it moves up and down, thus preventing the syrup from being carried into the sleeve.

[0031] 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 scope of protection of the present utility model.

[0032] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0033] This application discloses a filtering device. (Refer to...) Figure 1 and Figure 2 A filtration device includes a filter cylinder 1; a heating component 2 is connected to the outside of the filter cylinder 1, a filter component 3 is connected to the inside of the filter cylinder 1, and a filter component 4 is connected to the lower end of the filter cylinder 1.

[0034] The filter assembly 3 includes a cover plate 301, which is threaded to the upper end of the filter cartridge 1. A drive motor 302 is fixedly connected to the upper end of the cover plate 301. A drive shaft 303 is fixedly connected to the output end of the drive motor 302. A spiral guide vane 304 is fixedly connected to the outside of the drive shaft 303. A sleeve 305 is installed at the lower end of the drive shaft 303. Flanges 306 are fixedly connected to the outside of both the sleeve 305 and the drive shaft 303. The upper and lower flanges 306 are detachably connected by locking bolts 307. A limiting piece 308 is slidably connected to the sleeve 305. A locking block 309 is fixedly connected to the outside of the limiting piece 308. A sliding groove adapted to the locking block 309 is opened on the inner wall of the sleeve 305. 9 is slidably engaged with the slide groove. A spring 310 is fixedly connected to the upper end of the limiting piece 308. The other end of the spring 310 is fixedly connected to the sleeve 305. A movable rod 311 is fixedly connected to the lower end of the limiting piece 308. The movable rod 311 passes through the sleeve 305 and is slidably connected to the sleeve 305. Multiple scrapers 312 are fixedly connected to the outside of the movable rod 311. The scrapers 312 slide against the outer wall of the sleeve 305. Multiple positioning plates 313 are fixedly connected to the inner wall of the filter cylinder 1. Positioning posts 314 are fixedly connected to the upper ends of the multiple positioning plates 313. The external part of the drive shaft 303 is movably disposed on the filter screen 315. A central hole 316 is opened in the center of the filter screen 315. Multiple positioning grooves 317 are opened at the lower end of the filter screen 315.

[0035] By setting up filter assembly 3, in the initial state, the upper end of scraper 312 is tightly attached to the lower surface of filter screen 315. When candy raw materials such as syrup enter the filter cylinder 1 for filtration, the syrup flows forward, and scraper 312 moves downward under fluid pressure. A suitable spring 310 is selected so that scraper 312, after being compressed, drives spring 310 to stretch, maintaining a small gap between scraper 312 and filter screen 315, thus not affecting the normal filtration effect of filter screen 315. When blockage occurs, the pressure on scraper 312 decreases, spring 310 rebounds, and scraper 312 returns to its original position, allowing scraper 312 to adhere to filter screen 315. The drive motor 302 then drives the transmission shaft 303 to rotate, ultimately rotating scraper 312 to scrape away blockages from all directions on filter screen 315. This method does not require... The filter screen 315 is designed to react immediately to blockages and address them promptly. Furthermore, the drive shaft 303 rotates the spiral guide plate, which forces the syrup through the filter screen 315 in a vortex manner, preventing localized crystallization on the filter screen surface and evenly distributing fluid pressure. When installing the filter screen 315, first pass the drive shaft 303 through the central hole 316, then secure the two flanges 306 with locking bolts 307. Next, place the filter screen 315 on the positioning plate 313 from top to bottom, inserting the positioning pin 314 into the positioning hole. Finally, tighten the cover plate 301. After tightening, the sleeve 305 and scraper 312 fit snugly against the bottom of the filter screen 315. The positioning hole and positioning pin 314 position and restrict the filter screen 315, preventing it from moving freely.

[0036] Reference Figures 1-6 The outer surface of the movable rod 311 is coated with an anti-stick coating. The diameters of the drive shaft 303 and flange 306 are both smaller than the diameter of the central hole 316. The drive shaft 303 and flange 306 both penetrate the central hole 316. The diameter of the sleeve 305 is larger than the diameter of the central hole 316.

[0037] By coating the outer surface of the movable rod 311 with an anti-stick coating, such as a Teflon coating, the surface of the movable rod 311 will not be covered with syrup when it moves up and down, thus preventing the syrup from being carried into the sleeve 305.

[0038] Reference Figures 1-6 The positioning post 314 is movably inserted into the positioning groove 317, and the positioning post 314 is adapted to the positioning groove 317.

[0039] Reference Figures 1-6 The drive shaft 303 is rotatably connected to the cover plate 301, and the locking bolt 307 is threadedly connected to the flange 306.

[0040] Reference Figure 1The upper end of the cover plate 301 is fixedly connected to the feed pipe 318, and the upper end of the feed pipe 318 is threadedly connected to the sealing cap 319.

[0041] By unscrewing the sealing cap 319, raw materials such as syrup for candy processing can be added into the filter cylinder 1 through the feed pipe 318.

[0042] Reference Figure 1 , Figure 7 and Figure 8 The filter assembly 4 includes a discharge pipe 401, which is fixedly connected to the lower end of the filter cylinder 1. The lower end of the discharge pipe 401 is connected to a filter 402. Both the filter 402 and the discharge pipe 401 are fixedly connected to a flange 403. The upper and lower flanges 403 are detachably connected by locking bolts 404, which are threadedly connected to the flanges 403.

[0043] Reference Figure 1 , Figure 7 and Figure 8 The inner wall of filter 402 is threaded with a permanent magnet grid 405. The upper end of the permanent magnet grid 405 is connected to a handle 406. The lower end of filter 402 is fixedly connected to a connecting pipe 407. The external pipe of the connecting pipe 407 is connected to a discharge valve 408.

[0044] By setting up filter assembly 2 4, flange 2 403 and locking bolt 2 404, the filter 402 with the diameter of discharge pipe 401 can be easily installed and disassembled, and the filter 402 can be easily removed for cleaning. The permanent magnet grid 405 can adsorb and filter some magnetic metal impurities in the syrup due to mechanical wear and other reasons. By opening the discharge valve 408, the filtered candy raw materials can be discharged.

[0045] Reference Figure 1 and Figure 9 The heating assembly 2 includes a heating sleeve 201, which is fixedly connected to the outside of the filter cartridge 1. An electric heating plate 202 is fixedly connected inside the heating sleeve 201. A temperature sensor 203 is fixedly embedded in the inner wall of the heating sleeve 201. A temperature controller 204 is fixedly connected to the front end of the heating sleeve 201.

[0046] By setting up heating component 2, temperature sensor 203 monitors the temperature of heating jacket 201 and heating cylinder and transmits the signal to temperature controller 204. The operator can then use temperature controller 204 to control the heating temperature of electric heating plate 202 which is electrically connected to it. Electric heating plate 202 can be heated when powered on.

[0047] Working principle: First, install the filter screen 315. First, pass the drive shaft 303 through the center hole 316, then fix the two flanges 306 with locking bolts 307. Then, place the filter screen 315 on the positioning plate 313 from top to bottom, and insert the positioning pin 314 into the positioning hole. Finally, tighten the cover plate 301. After tightening, the sleeve 305 and scraper 312 fit perfectly with the bottom of the filter screen 315. The positioning hole and positioning pin 314 can position and restrict the filter screen 315 to prevent it from moving freely.

[0048] Unscrew the sealing cap 319, and you can add raw materials such as syrup for candy processing into the filter cylinder 1 through the feed pipe 318. Drive motor 302 drives transmission shaft 303 and spiral guide plate to rotate. The spiral guide plate can force the syrup to pass through the filter screen 315 in the form of vortex, prevent the syrup from crystallizing locally on the surface of the filter screen, and evenly disperse the fluid pressure.

[0049] Temperature sensor 203 monitors the temperature of heating jacket 201 and heating cylinder and transmits the signal to temperature controller 204. The operator can then use temperature controller 204 to control the heating temperature of electric heating plate 202 which is electrically connected to it. Electric heating plate 202 can heat candy raw materials when powered on.

[0050] When candy ingredients such as syrup enter the filter cylinder 1 for filtration, the syrup flows forward, and the scraper 312 moves downward under fluid pressure. A suitable spring 310 is selected so that the scraper 312 stretches the spring 310 after being pressed, and the scraper 312 and the filter screen 315 maintain a small gap, so as not to affect the normal filtration effect of the filter screen 315. When blockage occurs, the pressure on the scraper 312 decreases, the spring 310 rebounds, and the scraper 312 is driven to return to its original position, so that the scraper 312 fits against the filter screen 315. The drive motor 302 drives the transmission shaft 303 to rotate, and finally drives the scraper 312 to rotate, scraping the blockage of the filter screen 315 from all directions. This method does not require penetrating the blockage of the filter screen 315, and can react immediately when blockage occurs, and deal with the blockage in time.

[0051] Finally, the permanent magnet grid 405 can adsorb and filter some magnetic metal impurities in the syrup due to mechanical wear and other reasons. By opening the discharge valve 408, the filtered candy raw materials can be discharged.

[0052] 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.
