Description

Technical Field

[0001] This utility model relates to the technical field of solution filtration equipment, specifically to a solution extraction filter. Background Technology

[0002] A solution is a uniform and stable dispersion system formed by mixing two or more substances. During the preparation of a solution, it may contain impurities, so a filter is needed to purify the prepared solution.

[0003] Chinese utility model patent application number 201721424415.7, entitled "An Extraction Filter for Beverages," discloses an extraction filter for beverages, including a fixed box. A first motor is fixedly connected to the bottom of the inner wall of the fixed box via a base. A first bevel gear is fixedly connected to the output shaft of the first motor. A second bevel gear meshes with the surface of the first bevel gear, and a rotating shaft passes through the middle of the second bevel gear. A rotating plate is fixedly connected to the top of the rotating shaft, and a second motor is fixedly connected to the top of the rotating plate. A first pulley is fixedly connected to the output shaft of the second motor, and a second pulley is connected to the surface of the first pulley via a belt drive. This extraction filter for beverages solves the problem of insufficient extraction and filtration in current extraction filters used for beverages, which may require multiple extraction and filtration processes. It intelligently controls the constant temperature required during extraction and filtration, improving beverage production efficiency, saving production costs, and ensuring beverage production quality.

[0004] In the aforementioned patent, multiple purification filter plates of different specifications are used to filter and purify the solution. Larger residues on the top filter plate are cleaned by pulling it. It is known that during the purification and filtration process, in addition to residues on the top filter plate, impurities also remain on the different layers of the internal purification filter plates. If these residues are not cleaned in time, the more residues accumulate, the more likely they are to clog the purification filter plates, thus affecting the purification and filtration of the solution. Existing filtration devices often use a drive source to rotate a cleaning brush, moving the residues on the filter device to reduce the possibility of residue accumulation and clogging. However, this method cannot directly remove the residues from the filter device. More residues will affect the speed at which the solution seeps out of the filter device, thus reducing the overall solution extraction rate. Utility Model Content

[0005] The purpose of this invention is to provide a solution extraction filter to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solution extraction filter, comprising a filter housing, an inlet provided on the filter housing, and a filter device disposed inside the filter housing; a cleaning assembly for cleaning the filter device disposed inside the filter housing, and a collection assembly for collecting impurities on the filter device disposed on one side of the filter housing; the cleaning assembly includes a rotating rod rotatably connected in the filter housing, a plurality of cleaning plates disposed on the rotating rod, the projection position of the inlet corresponding to the cleaning plates, and the impurities on the filter device being cleaned during the rotation stroke of the cleaning plates.

[0007] Furthermore, the filtration device includes an arc-shaped filter frame disposed on the filter housing, and the arc-shaped filter frame is provided with a filter screen.

[0008] Furthermore, the collection assembly includes a collection frame disposed on the filter housing, and a through groove is provided between the collection frame and the filter housing; a guide plate is disposed in the through groove, and one side of the guide plate is fixedly connected to the arc-shaped filter frame.

[0009] Furthermore, a unclogging component is elastically connected to the bottom of the arc-shaped filter frame, and a locking unit is provided inside the filter housing for limiting the use of the unclogging component. When the filter screen is clogged, the locking unit unlocks to release the unclogging component, and the unclogging component elastically fits against the filter screen.

[0010] Furthermore, the unblocking component includes an elastic telescopic rod fixedly connected to the arc-shaped filter frame, and a movable plate fixedly connected to the bottom end of the elastic telescopic rod. Multiple rubber balls are arranged on the movable plate through multiple support rods.

[0011] Furthermore, the movable plate is provided with a snap-fit ​​unit, the snap-fit ​​unit including a wedge-shaped rod slidably connected in the movable plate, and a first spring is provided between the wedge-shaped rod and the movable plate.

[0012] Furthermore, the locking unit includes a fixing block disposed on the filter box, a connecting plate slidably connected inside the fixing block, a wedge block and a second spring disposed on the connecting plate, the elastic force of the second spring driving the connecting plate to move the wedge block back; a vertical rod slidably connected to the fixing block, a connecting rod rotatably connected between one end of the vertical rod and the connecting plate, and a water receiving plate fixedly connected to the bottom end of the vertical rod.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: 1. This solution extraction filter, through the coordinated arrangement of a filter housing, inlet, filtration device, cleaning component, and collection component, effectively purifies the solution passing through the inlet by filtering the filtration device. Simultaneously, as the solution enters the filter housing, it drives the rotating rod and multiple cleaning plates to rotate. The rotation of these cleaning plates moves the filtered impurities to the collection component. This device effectively cleans the residue remaining on the filter, preventing clogging. Furthermore, this device requires no external power source to clean the filter, making it highly practical.

[0014] 2. This solution extraction filter can unclog the filter screen by setting a clearing component at the bottom of the filtration device. By setting a locking unit at the bottom of the clearing component, the locking unit moves slowly as the water flow decreases when the filter screen is blocked. When the water flow decreases to a certain amount, the locking unit separates from the snap-fit ​​unit on the clearing component, thereby allowing the elastic telescopic rod in the clearing component to restore its restoring force. This causes the rubber ball of the moving plate to rebound and collide with the filter screen, thus effectively clearing the blockage. Attached Figure Description

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0018] like Figure 1-7 The present invention discloses a solution extraction filter, comprising a filter housing 1, an inlet 2 thereon on the filter housing 1, and a filter device inside the filter housing 1; a cleaning assembly for cleaning the filter device is provided inside the filter housing 1, and a collection assembly for collecting impurities on the filter device is provided on one side of the filter housing 1; the cleaning assembly includes a rotating rod 301 rotatably connected in the filter housing, and multiple cleaning plates 302 are provided on the rotating rod 301, the projection position of the inlet 2 corresponding to the cleaning plate 302, and the multiple cleaning plates 302 cleaning impurities on the filter device during their rotation stroke.

[0019] Specifically, the system includes a filter housing 1, which is an existing structure and will not be described in detail here. The filter housing 1 has an inlet 2, which can be configured as a hopper to facilitate the introduction of the solution into the filter housing 1. A filter device is installed inside the filter housing 1, located below the inlet 2. A cleaning assembly for cleaning the filter device is also installed inside the filter housing 1. A collection assembly for collecting impurities from the filter device is located on one side of the filter housing 1. This collection assembly allows for the collection of filtered residue, preventing excessive accumulation of residue on the filter device and ensuring optimal filtration efficiency. The cleaning assembly includes a rotating connection to the filter housing. The filter box contains a rotating rod 301 with multiple cleaning plates 302 arranged in a circular array on its outer surface. The projection position of the feed inlet 2 corresponds to that of the cleaning plates 302. During the rotation of the multiple cleaning plates 302, impurities on the filter device are cleaned. After the external solution enters the filter box 1 through the feed inlet 2, it will synchronously push the cleaning plates 302 to rotate. The rotation of the cleaning plates 302 can drive the rotating rod 301 to rotate, and the rotation of the rotating rod 301 can synchronously drive the multiple cleaning plates 302 to rotate, thereby pushing the residue remaining on the filter device to the collection component for collection.

[0020] In a further embodiment of this utility model, the filtration device includes an arc-shaped filter frame 401 disposed on the filter housing 1, and the arc-shaped filter frame 401 is provided with a filter screen 402.

[0021] Preferably, the filtration device includes an arc-shaped filter frame 401 mounted on the filter housing 1. The arc-shaped filter frame 401 is composed of a vertical plate and an arc-shaped plate, wherein the center point of the arc-shaped plate needs to be consistent with the center point of the rotating rod 301. The arc-shaped filter frame 401 is provided with a filter screen 402, which is arc-shaped and is located in the arc-shaped filter frame 401, so that the cleaning plate 302 can rotate to clean the residue on the filter screen 402.

[0022] In a further embodiment of this utility model, the collection component includes a collection frame 501 disposed on the filter box 1, and a through groove is provided between the collection frame 501 and the filter box 1; a guide plate 502 is disposed in the through groove, and one side of the guide plate 502 is fixedly connected to the arc-shaped filter frame 401.

[0023] Preferably, the collection component includes a collection frame 501 disposed on the filter housing 1. The collection frame 501 is detachably fixed to one side of the filter housing 1 and is disposed on the side where multiple cleaning plates 302 rotate counterclockwise. This allows the solution in the feed inlet 2 to push the cleaning plates 302 to rotate counterclockwise, thereby moving the residue on the filter screen 402 into the collection frame 501. A through groove is provided between the collection frame 501 and the filter housing 1. A guide plate 502 is disposed in the through groove. One side of the guide plate 502 is fixedly connected to the arc-shaped filter frame 401. By providing the through groove and the guide plate 502, it is convenient to guide the residue moved by the cleaning plates 302 into the collection frame 501.

[0024] In a further embodiment of this utility model, the bottom of the arc-shaped filter frame 401 is elastically connected to a unclogging component, and the filter box 1 is provided with a locking unit for limiting the use of the unclogging component. When the filter screen 402 is blocked, the locking unit is unlocked to release the unclogging component, and the unclogging component elastically fits the filter screen 402.

[0025] Preferably, the bottom of the arc-shaped filter frame 401 is elastically connected to a unclogging component, and the filter housing 1 is provided with a locking unit for limiting the unclogging component. When the filter screen 402 is blocked, the locking unit is unlocked to release the unclogging component. The unclogging component elastically fits against the filter screen 402, and the elastic movement of the unclogging component can collide with the filter screen 402, so that the residue stuck on the filter screen 402 can be shaken, making it easier for the residue stuck on the filter screen 402 to separate from the filter screen 402, thereby achieving a certain unclogging effect.

[0026] In a further embodiment of this utility model, the unblocking component includes an elastic telescopic rod 601 fixedly connected to the arc-shaped filter frame 401. A movable plate 602 is fixedly connected to the bottom end of the elastic telescopic rod 601, and multiple rubber balls 603 are provided on the movable plate 602 through multiple support rods.

[0027] Preferably, the unblocking component includes an elastic telescopic rod 601 fixedly connected to the arc-shaped filter frame 401. A movable plate 602 is fixedly connected to the bottom end of the elastic telescopic rod 601. Multiple elastic telescopic rods 601 can be set on the arc-shaped filter frame 401 to ensure the stability of the movable plate 602 connection. Multiple rubber balls 603 are set on the movable plate 602 through multiple support rods. When the movable plate 602 is in contact with the filter screen 402, the rubber balls 603 on the top support rod will push the filter screen 402 downward. With the rotation of the cleaning plate 302, the lifted filter screen 402 can be reset. The center point of the movable plate 602 is solid, while the rest can be hollow to allow water leaking from the filter screen 402 to impact the movable plate 602 and move it downward.

[0028] In a further embodiment of the present invention, a snap-fit ​​unit is provided on the movable plate 602. The snap-fit ​​unit includes a wedge-shaped rod 701 slidably connected in the movable plate 602, and a first spring 702 is provided between the wedge-shaped rod 701 and the movable plate 602.

[0029] Preferably, the movable plate 602 is provided with a snap-fit ​​unit, which includes a wedge-shaped rod 701 slidably connected in the movable plate 602. The movable plate 602 is provided with a groove for the movement of the wedge-shaped rod 701, so that the wedge-shaped rod 701 can move in the movable plate 602. The bottom of the end of the wedge-shaped rod 701 away from the movable plate 602 is provided as an inclined surface. A first spring 702 is provided between the wedge-shaped rod 701 and the movable plate 602. The elastic force of the first spring 702 drives the wedge-shaped rod 701 to move outward.

[0030] In a further embodiment of this utility model, the locking unit includes a fixing block 801 disposed on the filter box 1. A connecting plate 802 is slidably connected inside the fixing block 801. A wedge block 807 and a second spring 803 are disposed on the connecting plate 802. The elastic force of the second spring 803 drives the connecting plate 802 to retract and move the wedge block 807. A vertical rod 804 is slidably connected on the fixing block 801. A connecting rod 805 is rotatably connected between one end of the vertical rod 804 and the connecting plate 802. A water receiving plate 806 is fixedly connected to the bottom end of the vertical rod 804.

[0031] Preferably, the locking unit includes a fixing block 801 disposed on the filter housing 1. Multiple sets of fixing blocks 801 can be provided in the locking unit, and these sets are evenly distributed at the four corners of the bottom of the moving plate 602. A connecting plate 802 is slidably connected inside the fixing block 801. A groove for the moving plate 802 is provided inside the fixing block 801. A wedge block 807 and a second spring 803 are provided on the connecting plate 802. The wedge block 807 and the second spring 803 are respectively fixed on both sides of the connecting plate 802. The elastic force of the second spring 803 drives... The connecting plate 802 drives the wedge block 807 to retract and move; a vertical rod 804 is slidably connected to the fixed block 801, and a connecting rod 805 is rotatably connected between one end of the vertical rod 804 and the connecting plate 802. A water receiving plate 806 is fixedly connected to the bottom end of the vertical rod 804. When the second spring 803 is in a free state, the wedge block 807 on the moving plate 602 will retract into the fixed block 801. The center of the water receiving plate 806 also needs to be set to be solid, and the solid area of ​​the center of the water receiving plate 806 is larger than the solid area of ​​the center of the moving plate 602.

[0032] During operation, the solution to be purified and filtered is poured into the filter box 1 through the inlet 2. The solution falls onto the filter screen 402 on the filter box 1 for filtration. When the solution enters the filter box 1, it will drive the cleaning plate 302 in the filter box 1 to rotate. The rotation of the cleaning plate 302 will drive the rotating rod 301 to rotate, so that the other cleaning plates 302 on the rotating rod 301 will rotate synchronously and make a circular motion. This will push the residue on the filter screen 402 to move until the residue moves to the guide plate 502 connected to one end of the filter screen 402. The residue will fall into the collection frame 501 for collection through the guide plate 502 and the channel. The filtered solution will pass through the filter screen 402 and fall onto the moving plate 602. Since the filter screen 402 is not clogged at this time, the water flow through the filter screen 402 is large. When the water flow is large, the impact force of the water flow is also large, which can push the moving plate 602 to move the elastic telescopic rod 601 until the moving plate 602 moves below the fixed block 801. At the same time, the water flow impacts the moving plate 602 and also impacts the water receiving plate 806 at the bottom of the moving plate 602, thereby causing the water receiving plate 806 to move. The water receiving plate 806 moves outward via the vertical rod 804 and the connecting rod 805, which can pull the connecting plate 802 in the fixed block 801 to move outward. The movement of the connecting plate 802 can drive the wedge block 807 to move to the outside of the fixed block 801. At the same time, the movement of the connecting plate 802 will also stretch the second spring 803, causing the second spring 803 to deform. After the wedge block 807 moves to the outside of the fixed block 801, it can limit the wedge rod 701 on the moving plate 602. When the filter screen 402 becomes clogged, the amount of solution filtered by the filter screen 402 will slowly decrease. At this time, the impact force of the water flow on the moving plate 602 and the water receiving plate 806 will also decrease. The restoring force of the elastic telescopic rod 601 on the moving plate 602 will drive the moving plate 602 to move and reset. When the moving plate 602 moves to the same height as the fixed block 801, the wedge rod 701 inside will be limited by the wedge block 807, so that the moving plate 602 can not move further. When the impact force on the water receiving plate 806 decreases, the second spring 8 inside the fixed block 801 will... The restoring force 03 will pull the connecting plate 802 to move. The movement of the connecting plate 802 will pull the wedge block 807 to move slowly into the interior of the fixed block 801. When the wedge block 807 moves into the interior of the fixed block 801, the restoring force of the elastic telescopic rod 601 will instantly return, causing the moving plate 602 to fit against the filter screen 402. The rubber ball 603 on the moving plate 602 will abut against the filter screen 402 and shake, causing the residue blocked in the filter screen 402 to move. This makes it easier for the cleaning plate 302 to rotate and clean away the blocked residue.
