Description

Technical Field

[0001] This utility model relates to the field of salad dressing processing technology, and in particular to a salad dressing raw material filtering device. Background Technology

[0002] Chinese Patent Publication No. CN220424690U discloses a salad dressing filtration and extraction device, including a stirring device, an auxiliary device, a control panel, a stirring rod, a filtration structure, and a support frame. This utility model, by setting an auxiliary device at the lower end of the stirring device, with a filter screen inside that works in conjunction with the stirring rod, can quickly remove impurities, while also greatly improving filtration efficiency and reducing working time.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: The device mainly relies on the gravity of the salad dressing ingredients for filtration. Since the salad dressing ingredients are sticky, they are easy to accumulate on the surface of the filter screen. Moreover, during natural filtration, the material passes through the filter screen only by its own gravity, resulting in a slow filtration rate. Especially when dealing with high-viscosity salad dressings, the filter screen is prone to clogging and filtration interruption. Secondly, although the stirring component can agitate the material, it is also easy for air bubbles to be generated and mixed into the material, further hindering filtration. Utility Model Content

[0004] The technical problem to be solved by this invention is that existing technologies rely solely on gravity for natural filtration, which can easily reduce the filtration rate for viscous materials like salad dressing ingredients. Therefore, we propose a salad dressing ingredient filtration device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a salad dressing raw material filtering device, comprising a filter cylinder, supports equidistantly fixed on the outer side of the filter cylinder, a filter plate fixed at the bottom inside the filter cylinder, an end cap covering the top of the filter cylinder, a feed pipe provided on one side of the filter cylinder, guide rods penetrating both sides of the end cap, and a pressure plate connected to the bottom of the guide rods, the outer diameter of the pressure plate matching the inner diameter of the filter cylinder, a sealing ring provided on the contact surface between the pressure plate and the filter cylinder, the bottom end face of the pressure plate being conical, the curvature of the bottom end face of the pressure plate matching the curvature of the end face of the filter plate, and the end cap... A rotating tube runs through the center. A self-rotating assembly connects the top of the end cap to the rotating tube. A connecting plate is fitted onto the top of the rotating tube. An electric telescopic rod is fixed to one side of the bottom of the connecting plate. The bottom of the electric telescopic rod is fixedly connected to the inside of the end cap. The bottom of the rotating tube passes through the center of the pressure plate and is connected to a flow guide cap. A retaining ring is fixed to the outside of the rotating tube. The bottom of the retaining ring abuts against the top of the pressure plate. An inclined tube is connected to one side of the flow guide cap. The top of the inclined tube is attached to the bottom of the pressure plate. Nozzles A and B are equidistantly arranged on the inclined tube. Nozzle C is arranged at the end of the inclined tube away from the flow guide cap.

[0006] Preferably, the filter cartridge is transparent, the distance between the feed pipe and the end cap is smaller than the distance between the feed pipe and the filter plate, and the pressure plate is located above the feed pipe in the initial state.

[0007] Preferably, the end cap is screwed onto the top of the filter cylinder by threads, and the filter plate is installed at a height of 1 cm from the bottom of the filter cylinder.

[0008] Preferably, the top end of the rotating tube is rotatably connected to the shaft tube located inside the connecting plate, and a quick connector is installed at the top end of the shaft tube, and the rotating tube and the pressure plate are rotatably connected.

[0009] Preferably, the self-rotating assembly includes a fixing ring fixed to the top of the end cap, the fixing ring being sleeved on the outside of the rotating tube, a fixing slider being fixed on the inner wall of the fixing ring, a spiral groove being formed on the outer wall of the rotating tube, the outer side of the fixing slider being in contact with the inner wall of the spiral groove, and the distribution length of the spiral groove being equal to the distance between the pressure plate and the filter plate in the initial state.

[0010] Preferably, nozzles A and B are spaced apart in the inclined tube, with the spray direction of nozzle A inclined to the bottom end face of the pressure plate, the spray direction of nozzle B perpendicular to the top end face of the filter plate, and the spray direction of nozzle C perpendicular to the inner wall of the filter cylinder.

[0011] Preferably, a magnetic ring is embedded inside the pressure plate near the inner wall of the filter cylinder, and a magnetic block is embedded on the side of the inclined tube near the pressure plate, with the magnetic block positioned directly opposite the magnetic ring, and the magnetic block and the magnetic ring attracting each other.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, an electric telescopic rod drives the pressure plate to rise and fall, creating a pressurized environment with the sealing ring. This significantly accelerates the passage of viscous salad dressing ingredients through the filter plate, solving the problem of slow natural filtration. The self-rotating component drives the rotating tube and the inclined tube to rotate synchronously. Combined with the design of the pressure plate's conical surface and the inclined tube fitting together, it reduces the adhesion of ingredients at the bottom of the pressure plate, minimizing material waste. The attraction of the magnetic ring and magnetic block further ensures the fit between the inclined tube and the pressure plate, enhancing the scraping effect. After filtration, a quick connector connects to a water source, and multi-directional nozzles can separately rinse the bottom of the pressure plate, the filter plate, and the inner wall of the filter cylinder, ensuring thorough cleaning. The transparent filter cylinder facilitates observation of the material quantity, while the threaded end cap and detachable parts improve maintenance convenience. The overall device balances filtration efficiency, material utilization, and cleanliness, significantly improving the quality and efficiency of salad dressing ingredient filtration.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figures 1-2As shown, this utility model provides a technical solution: a salad dressing raw material filtering device, including a filter cylinder 1, with supports 3 fixed at equal intervals on the outer side of the filter cylinder 1. The supports are fixed to the outer wall of the filter cylinder by welding or bolts. The bottom of the supports is provided with an anti-slip pad to ensure that the device is stable and does not shift when placed. A filter plate 10 is fixed to the bottom of the filter cylinder 1. The edge of the filter plate is tightly fitted to the inner wall of the filter cylinder. The two are sealed with sealant or welding to prevent unfiltered salad dressing raw material from leaking through the gaps. The filter plate is horizontally set to ensure uniform filtration area. The top of the filter cylinder 1 is covered with an end cap 2. The connection surface between the end cap and the top of the filter cylinder is provided with a sealing gasket to enhance the overall sealing performance and prevent air leakage during pressurized filtration. A feed pipe 4 is provided on one side of the filter cylinder 1. The feed pipe is inclined and connected to the side wall of the filter cylinder. The inner side of the feed pipe opening is rounded to reduce resistance and residue when introducing salad dressing ingredients. Guide rods 91 are inserted through both sides of the end cap 2. A linear bearing is installed between the guide rod and the through hole of the end cap to ensure smooth and unobstructed movement of the guide rod. The bottom end of the guide rod 91 is connected to the pressure plate 9. The guide rod and the pressure plate are fixed by threads or welding to ensure that the pressure plate is evenly stressed and does not tilt when it is raised or lowered. The outer diameter of the pressure plate 9 is matched with the inner diameter of the filter cylinder 1. A sealing ring is provided on the contact surface between the pressure plate 9 and the filter cylinder 1. The sealing ring is made of food-grade rubber and fits tightly against the inner wall of the filter cylinder to prevent air leakage from the gap between the pressure plate and the cylinder wall during pressurization. The bottom end face of the pressure plate 9 is conical and the curvature of the bottom end face of the pressure plate 9 is close to the inner wall of the filter cylinder. The end face curvature of the filter plate 10 is adjusted to ensure uniform material compression when the pressure plate descends; a rotating tube 7 passes through the center of the end cover 2, and a sealed bearing is provided between the rotating tube and the end cover to ensure both sealing and smooth rotation; a self-rotating component 8 is connected between the top of the end cover 2 and the rotating tube 7, and the self-rotating component is fixed to the top of the end cover by a bracket to limit the rotation trajectory of the rotating tube; a connecting plate 6 is fitted onto the top of the rotating tube 7, and the rotating tube and the shaft tube inside the connecting plate are rotatably connected by a bearing; an electric telescopic rod 5 is fixed to one side of the bottom end of the connecting plate 6, and the electric telescopic rod is fixed to the connecting plate and the end cover by bolts to ensure stable power transmission; the bottom end of the electric telescopic rod 5 is fixedly connected to the inside of the end cover 2, and the bottom end of the rotating tube 7 passes through the center of the pressure plate 9 and is connected to the end cover 2. A flow guide cap tube 73 is provided, and the rotating tube is connected to the flow guide cap tube by welding or threaded sealing. A retaining ring 72 is fixed to the outside of the rotating tube 7 by welding, which forms a vertical limit on the pressure plate. The bottom end of the retaining ring 72 abuts against the top end of the pressure plate 9. One side of the flow guide cap tube 73 is connected to an inclined tube 74, which is connected to the flow guide cap tube by thread for easy disassembly and replacement. The top end of the inclined tube 74 is attached to the bottom end of the pressure plate 9. Spray nozzles A75 and B76 are equidistantly arranged on the inclined tube 74. The spray nozzles are connected to the inclined tube by thread for easy maintenance and cleaning. A spray nozzle C77 is provided at the end of the inclined tube 74 away from the flow guide cap tube 73. Spray nozzles A75, B76 and C77 are all unidirectional spray nozzles to ensure that the fluid is sprayed out in one direction without backflow.

[0023] By shortening the electric telescopic rod 5, the pressure plate 9 moves closer to the filter plate 10, compressing the air space above the salad dressing ingredients. This creates a downward squeezing effect, promoting the salad dressing ingredients to be discharged from the filter holes of the filter plate 10. This reduces the stickiness of the salad dressing ingredients on the filter plate 10 under natural filtration, increasing the filtration rate. The self-rotating component 8 enables the nozzle A75 to rotate during the lifting process, thereby reducing the adhesion of salad dressing ingredients to the bottom of the pressure plate 9 and minimizing waste.

[0024] Reference Figure 2 As shown in this embodiment: the filter cylinder 1 is transparent, the distance between the feed pipe 4 and the end cap 2 is smaller than the distance between the feed pipe 4 and the filter plate 10, and the pressure plate 9 is located above the feed pipe 4 in the initial state to prevent the pressure plate 9 from obstructing the salad dressing raw materials from entering the interior of the filter cylinder 1.

[0025] The transparent material of filter cartridge 1 is used to facilitate observation of the amount of salad dressing ingredients being introduced, thus preventing spillage.

[0026] Reference Figure 2 As shown, the end cap 2 is screwed onto the top of the filter cylinder 1 by threads, and the filter plate 10 is installed 1cm from the bottom of the filter cylinder 1 to prevent the salad dressing ingredients from splashing outwards during filtration.

[0027] The threaded design facilitates the disassembly of the end cover 2, thereby enabling regular inspection and maintenance of the internal components.

[0028] Reference Figure 1 As shown, the top end of the rotating tube 7 is rotatably connected to the shaft tube located inside the connecting plate 6. A quick connector 71 is installed at the top end of the shaft tube, and the rotating tube 7 and the pressure plate 9 are rotatably connected.

[0029] The shaft tube and quick connector 71 are used to facilitate quick connection to external water pipes, so that after filtration, water pipes can be directly connected for rinsing, while not hindering the rotation of the rotating tube 7 during lifting and lowering.

[0030] Reference Figure 2 , Figure 3 As shown, a self-rotating component 8 is provided at the center of the top of the end cap 2. The self-rotating component 8 includes a fixing ring 81 fixed to the top of the end cap 2. The fixing ring 81 is sleeved on the outside of the rotating tube 7. A fixing slider 82 is fixed on the inner wall of the fixing ring 81. A spiral groove 83 is opened on the outer wall of the rotating tube 7. The outer side of the fixing slider 82 and the inner wall of the spiral groove 83 are in contact. The distribution length of the spiral groove 83 is equal to the distance between the pressure plate 9 and the filter plate 10 in the initial state.

[0031] By utilizing the sliding of the fixed slider 82 inside the spiral groove 83, the rotating tube 7 can automatically generate a rotational action when it is raised and lowered, thereby causing the inclined tube 74 to rotate along the bottom end of the pressure plate 9. The rotational action can, on the one hand, scrape the sticky salad dressing ingredients to reduce adhesion, and on the other hand, facilitate the subsequent rotational rinsing action.

[0032] Reference Figure 4 , Figure 5 As shown, nozzles A75 and B76 are spaced apart in the inclined tube 74. The spray direction of nozzle A75 is inclined to the bottom end face of the pressure plate 9, the spray direction of nozzle B76 is perpendicular to the top end face of the filter plate 10, and the spray direction of nozzle C77 is perpendicular to the inner wall of the filter cylinder 1.

[0033] The nozzle A75 can be used to rotate and rinse the bottom surface of the pressure plate 9 during the rotation of the inclined tube 74, and to impact the residual salad dressing ingredients at an angle to reduce secondary adhesion. At the same time, the nozzle B76 can be used to directly rinse the filter plate 10 below, and the nozzle C77 can be used to rinse the inner wall of the filter cylinder 1.

[0034] Reference Figure 5 As shown, a magnetic ring 742 is embedded inside the pressure plate 9 near the inner wall of the filter cylinder 1, and a magnetic block 741 is embedded on the side of the inclined tube 74 near the pressure plate 9. The magnetic block 741 is positioned directly opposite the magnetic ring 742, and the magnetic block 741 and the magnetic ring 742 attract each other.

[0035] The attraction between the magnetic ring 742 and the magnetic block 741 is used to improve the fit between the distal end of the inclined tube 74 and the bottom end face of the pressure plate 9. This allows the inclined tube 74 to scrape the salad dressing ingredients when rotating, while avoiding grooving on the bottom end face of the pressure plate 9 and improving the flatness and smoothness of the bottom end face of the pressure plate 9.

[0036] Working principle: The receiving device is placed directly below the filter cylinder 1. The salad dressing raw material is introduced into the filter cylinder 1 through the feed pipe 4. Since the salad dressing raw material has a certain viscosity, its filtration rate is slow under natural flow. Therefore, during filtration, the electric telescopic rod 5 is activated to shorten, which causes the connecting plate 6 to drive the rotating tube 7 to descend, thereby causing the pressure plate 9 to descend. The pressure plate 9 compresses the air space above the salad dressing raw material, thereby forcing the salad dressing raw material to pass through the filter plate 10 faster. Since the fixed slider 82 is always located inside the spiral groove 83 during the descent of the rotating tube 7, and the position of the fixed slider 82 is fixed, the rotating tube 7 rotates, thereby driving the inclined tube 74 to rotate. This avoids the salad dressing raw material sticking to the bottom surface of the pressure plate 9 when it comes into contact with the bottom surface of the pressure plate 9 during the subsequent pressurization process.

[0037] After filtration is complete, connect the external water pipe to the rotating pipe 7 via quick connector 71, and restart the electric telescopic rod 5 to rotate the inclined pipe 74 again. The water flow will then pass from the rotating pipe 7 through the guide cap pipe 73 and the inclined pipe 74, and be discharged from the nozzles A75, B76 and C77 respectively. This will achieve the rinsing effect on the bottom surface of the pressure plate 9, the top of the filter plate 10 and the inner wall of the filter cylinder 1, thereby reducing the cleaning impact. Alternatively, the end cap 2 can be unscrewed to disassemble the end cap 2 and the filter cylinder 1 for a thorough cleaning.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
