Description

Technical Field

[0001] The invention relates to the technical field of particle composite filling, in particular to an automatic filling device for a filter element. Background Art

[0002] The filter element is an important part of the water purifier. As a consumable, it needs to be replaced frequently. The filter element has various forms according to different situations, such as cotton thread type, exchange resin type, activated carbon type, etc. Among them, the activated carbon type is the most used. Generally speaking, there is a hollow cavity in the middle of the filter element filled with activated carbon particles to allow water to flow through. Due to the characteristics of the activated carbon particles themselves, they need to be filled and pressed during the filling process to make them tightly filled, but the current filling method is not effective and cannot achieve a compacting effect. It is easy to collapse during use, causing water to directly invade the hollow cavity, reducing the filtering effect of the filter element.

[0003] In addition, there is currently a method of filling the filter element using multiple hoses, which can improve efficiency compared to traditional manual filling. However, when the activated carbon particles enter the filter element from the material box, they will pass through the hoses. The discharge of the activated carbon particles in the hoses is greatly hindered, which in turn makes the flow rate of the activated carbon particles slower, resulting in the activated carbon particles not being able to keep up with the filling speed, thereby reducing the filling efficiency of the activated carbon particles; and because the activated carbon particles flow in multiple discharge hoses, the pressure in the hoses is inconsistent, resulting in uneven filling of the activated carbon particles into the water purification filter element, which easily affects the quality of the filter element, thereby increasing the number of defective filter elements during production; and when cleaning the device, multiple hoses need to be removed, and after cleaning, multiple hoses need to be installed one by one, which makes cleaning more cumbersome.

[0004] Therefore, we proposed an automatic filling equipment for filter elements. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic filling device for filter elements to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic filling device for a filter element, comprising a bracket, the bracket comprising a bottom plate, the upper side wall of the bottom plate is fixedly connected to a plurality of support rods, the support rods are provided with a first support plate and a second support plate in sequence from bottom to top, the lower side wall of the second support plate is fixedly connected to a switch mechanism, the upper side of the switch mechanism is connected to a material pipe, the upper end of the material pipe extends to the upper side of the second support plate and is connected to the feeding mechanism, the lower side of the switch mechanism is fixedly connected to a docking block, and the side walls of the switch mechanism and the docking block are both provided with a plurality of through holes;

[0007] The lower side of the first support plate is fixedly connected to a first driving mechanism, the output shaft of the first driving mechanism passes through the side wall of the first support plate and is fixedly connected to a lifting plate, the upper side of the lifting plate is fixedly connected to a base through a plurality of first bolts, and the lower side of the base is fixedly connected to a vibration mechanism.

[0008] Preferably, the switch mechanism includes a fixing frame, the four corners of which are fixedly connected to the lower side wall of the second support plate by second bolts, the lower side of the fixing frame is sequentially connected to a cover plate and a thickening ring, and the thickening ring is fixedly connected to a docking block, a turntable is rotatably connected between the cover plate, the thickening ring and the docking block, a lever is fixedly connected to the side wall of the turntable, the outer end of the lever is connected to the output shaft of the second driving mechanism through a waist-shaped hole, and the second driving mechanism is fixedly connected to the lower side wall of the second support plate.

[0009] Preferably, elastic pads are provided on the outer side wall of the first bolt and on both sides of the base, and elastic pads are also provided on the outer side wall of the second bolt and on both sides of the fixing frame.

[0010] Preferably, an annular groove is formed on the lower side of the docking block, a guide protrusion is provided at the center of the docking block and in the annular groove, and a positioning frame is fixedly connected to the center position of the upper side of the base.

[0011] Preferably, a plurality of guide pillars are fixedly connected to the upper side surface of the first support plate, a bushing is slidably sleeved on the outer side wall of the guide pillar, and the bushing is fixedly connected to the lifting plate.

[0012] Preferably, a limiting plate is connected to the periphery of the side wall of the docking block.

[0013] Preferably, a plurality of clamping blocks are sleeved on the outer side wall of the support rod, and the clamping blocks are fixedly connected to the side walls of the first support plate and the second support plate.

[0014] Preferably, the feeding mechanism comprises a material box and a lower hopper, the bottom end of the lower hopper is movably inserted into the material pipe, and the material box is mounted on the third support plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention guides the activated carbon particles inside the material box to the inside of the feed pipe through the lower hopper, and when the activated carbon particles inside the material pipe reach the height of the lower end of the lower hopper, the activated carbon particles are automatically stopped from being guided due to the interaction force of the particle accumulation, so that the height of the activated carbon particles in the material pipe is always level with the lower end of the lower hopper, so the pressure inside the material pipe is the same, and because the through holes are all on the bottom side wall of the material pipe, the pressure on each through hole comes from the pressure of the activated carbon particles inside the material pipe, so that the pressure of each through hole is the same, thereby ensuring that the flow rate of the activated carbon particles in each through hole is uniform;

[0016] In addition, the vibration mechanism can fill the activated carbon particles tightly, and then make the activated carbon particles filled into the filter element uniform, thereby improving the production processing quality; when the activated carbon particles in the material pipe are filled into the filter element, the activated carbon particles directly enter the filter element from the inside of the through hole, which greatly reduces the resistance of the activated carbon particles during flow, ensures the flow speed of the activated carbon particles, and then increases the efficiency of filling the activated carbon particles; because the material pipe has no contact with the lower hopper, when cleaning the material pipe, the material pipe can be directly removed to clean the material pipe, making the cleaning work simple and convenient;

[0017] In addition, the limit plate and positioning frame can make the placement process smoother, and the docking block can completely match the structure of the filter element. Even if there is a slight deviation during placement, it will still be corrected by the guide protrusion during the filling process, thereby completing the filling process smoothly.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-12 The present invention provides a technical solution: an automatic filling device for a filter element, comprising a bracket 1, wherein the bracket 1 comprises a bottom plate 101, and a plurality of support rods 102 are fixedly connected to the upper side wall of the bottom plate 101, and a first support plate 103 and a second support plate 104 are arranged on the support rod 102 from bottom to top in sequence, and the support rod 102 is a steel pipe with a smooth surface, which plays a supporting role for the first support plate 103 and the second support plate 104, and a switch mechanism 2 is fixedly connected to the lower side wall of the second support plate 104, and the switch mechanism 2 plays a role in cutting off and conducting the flow of activated carbon particles. When the switch mechanism 2 is opened, the activated carbon particles flow downward to fill the filling cavity, and when the switch mechanism 2 is closed, the activated carbon particles stop flowing downward, and a material pipe 3 is connected to the upper side of the switch mechanism 2, and the upper end of the material pipe 3 extends to the upper side of the second support plate 104 and is connected to the feeding mechanism.

[0033] The feeding mechanism can be directly input through an external material pump, or it can be a set material box 4, etc. Specifically, in order to ensure the stability of feeding, the feeding mechanism includes a material box 4 and a lower hopper 5, the bottom end of the lower hopper 5 is movably inserted in the material pipe 3, and the material box 4 is installed on the third support plate 105, and the third support plate 105 is also installed on the support rod 102. A mounting plate is fixedly welded to the upper end of the lower hopper 5. When the lower hopper 5 is installed, the mounting plate is attached to the side wall of the discharge port of the material box 4 and is fixed circumferentially with screws, so that the lower hopper 5 is connected to the discharge port of the material box 4 and sealed. The lower end of the lower hopper 5 extends to the interior of the material pipe 3. According to actual conditions, the lower end of the lower hopper 5 extends to the interior of the material pipe 3 to a depth of about 4-5 cm, and the lower hopper 5 has no contact with the material pipe 3. When the lower hopper 5 guides the activated carbon particles inside the material box 4 to the interior of the material pipe 3, when the activated carbon particles inside the material pipe 3 reach the lower port part of the lower hopper 5 (that is, the activated carbon particles inside the material pipe 3 are at the same height as the lower end of the lower hopper 5), the lower port part of the lower hopper 5 will be blocked by the activated carbon particles inside the material pipe 3, so that the activated carbon particles inside the lower hopper 5 The carbon particles automatically stop flowing downward. When the activated carbon particles in the material pipe 3 are filled into the filling cavity, the height of the activated carbon particles in the material pipe 3 drops and is lower than the height of the lower end of the lower hopper 5. At this time, the activated carbon particles in the lower hopper 5 flow downward to automatically fill the activated carbon particles in the material pipe 3. A docking block 6 is fixedly connected to the lower side of the switch mechanism 2. A plurality of through holes 8 are provided on the side walls of the switch mechanism 2 and the docking block 6 (if the material pipe 3 is provided with a bottom, the bottom of the material pipe 3 must also be provided with a plurality of corresponding through holes 8. If the bottom of the material pipe 3 has no bottom wall, it is not necessary). The activated carbon particles in the material pipe 3 flow into the filling cavity through the through holes 8. The through holes 8 (not limited to circular) are arranged in a circular array, so that the activated carbon particles in the filling cavity are filled more evenly.

[0034] The lower side of the first support plate 103 is fixedly connected with a first driving mechanism 9. Specifically, the first driving mechanism 9 can be a cylinder. The output shaft of the first driving mechanism 9 passes through the side wall of the first support plate 103 and is fixedly connected with a lifting plate 10. The upper side of the lifting plate 10 is fixedly connected with a base 12 through a plurality of first bolts 11. The output shaft of the first driving mechanism 9 can slide upward against the lifting plate 10 and the base 12, so that the upper end of the filter element is pushed into the annular groove 7 of the docking block 6, so that the through hole 8 is connected with the filling cavity of the filter element (such as Figure 8 As shown in FIG. 1 ), after the filling is completed, the output shaft of the first driving mechanism 9 pulls the lifting plate 10 and the base 12 to slide downward, and the filled filter element can be removed at this time. The lower side of the base 12 is fixedly connected with a vibration mechanism 13. Specifically, as shown in FIG. Figure 3The vibration mechanism 13 shown can adopt a polarization motor with an eccentric block. When the vibration mechanism 13 is started, the eccentric block on the output shaft of the polarization motor will rotate, thereby generating vibration. At this time, the base 12, the filter element and the material pipe 3 will all vibrate, thereby accelerating the activated carbon particles inside the material pipe 3 to quickly flow into the filling cavity.

[0035] What’s more important is that vibration can gradually compact the activated carbon particles inside the filling cavity, improve the uniformity of the filling effect, and then ensure the filtering effect of the filter element.

[0036] In addition, a positioning frame 14 is fixedly connected to the center position of the upper side of the base 12. The positioning frame 14 is a device for vertically placing the filter element, and elastic hoops are fixed around the positioning frame 14. After the filter element is placed on the positioning frame 14, the bottom is clamped by the elastic hoop, which can ensure that the filter element will not fall over, thereby ensuring the stability of the filling process.

[0037] Specifically, the switch mechanism 2 includes a fixing frame 201, the four corners of which are fixedly connected to the lower side wall of the second support plate 104 by second bolts 15, the lower side of the fixing frame 201 is sequentially connected with a cover plate 202 and a thickened ring 203, and the thickened ring 203 is fixedly connected to the docking block 6, the fixing frame 201, the cover plate 202, the thickened ring 203, and the docking block 6 are sequentially connected in series and fixed together by screws, and a turntable 204 is rotatably connected between the cover plate 202, the thickened ring 203 and the docking block 6, and a channel is opened on the turntable 204 that can completely overlap with the through hole 8 on the docking block 6. When the turntable 204 rotates, the channel on the turntable 204 will overlap and interlace with the through hole 8, thereby realizing the flow on and off of the activated carbon particles. In this state, a lever 205 is fixedly connected to the side wall of the turntable 204, and the outer end of the lever 205 is connected to the output shaft of the second drive mechanism 207 (the second drive mechanism 207 can specifically be a double-rod telescopic cylinder to prevent spinning) through a waist-shaped hole 206. The waist-shaped hole 206 is opened on the side wall of the lever 205, and the column rod fixed on the output shaft of the second drive mechanism 207 is sleeved inside the waist-shaped hole 206. When the output shaft of the second drive mechanism 207 is extended or retracted, the column rod slides inside the waist-shaped hole 206, and then the rotation of the lever 205 can be controlled. At this time, the lever 205 rotates with the turntable 204 to realize the flow of activated carbon particles. The second drive mechanism 207 is fixedly connected to the lower side wall of the second support plate 104.

[0038] Specifically, elastic pads 16 are provided on the outer wall of the first bolt 11 and on both sides of the base 12, and elastic pads 16 are also provided on the outer wall of the second bolt 15 and on both sides of the fixing frame 201. The elastic pads 16 are made of silicone material and have a certain elasticity, which can ensure that when the vibration mechanism 13 is started, the base 12, the filter element and the material pipe 3 can all vibrate, and ensure that the filter element and the docking block 6 can maintain a tight connection during the vibration process.

[0039] Specifically, the lower side of the docking block 6 is provided with an annular groove 7, and the center of the docking block 6 and the annular groove 7 are provided with a guide protrusion, such as Figure 8 As shown, the lower port of the annular groove 7 is relatively large, and the side wall of the annular groove 7 is provided with a guide protrusion to form a guide slope. Therefore, when there is a certain deviation in the placement of the filter element, the filter element slides upward, and the upper side wall of the filter element will slide along the slope surface of the annular groove 7. Finally, the filter element will be accurately snapped into the standard position of the annular groove 7 (different sizes of filter elements only need to replace the corresponding different docking blocks 6). At this time, the through hole 8 will be connected to the filling cavity.

[0040] In addition, when the operation of filling activated carbon particles is completed and the switch mechanism 2 is closed, a part of the activated carbon particles will remain inside the through hole 8 on the docking block 6. In order to effectively and reasonably deal with the activated carbon particles remaining in the through hole 8 on the docking block 6, the volume occupied by the guide protrusion inside the annular groove 7 is the same as the volume of the activated carbon particles remaining in the through hole 8. When the filter element is clamped into the annular groove 7, the guide protrusion is in the filter element, occupying part of the space in the filling cavity of the filter element. Therefore, when the filling task is completed, the space occupied by the guide protrusion in the filling cavity has not been filled. When the filter element slides downward, the guide protrusion will move out of the filling cavity. At this time, the activated carbon particles remaining in the through hole 8 just fall into the interior of the filling cavity (filling the space in the filling cavity originally occupied by the guide protrusion), which not only ensures that the filling cavity is filled in place, but also does not cause the phenomenon of wasting activated carbon particles.

[0041] Specifically, a plurality of guide pillars 17 are fixedly connected to the upper side surface of the first support plate 103, and a bushing 18 is slidably sleeved on the outer side wall of the guide pillar 17. The bushing 18 is fixedly connected to the lifting plate 10, and the bushing 18 has a certain length. The lifting plate 10 slides on the guide pillar 17 through the plurality of bushings 18, thereby ensuring the vertical lifting of the lifting plate 10 and preventing the lifting plate 10 from deflecting when sliding.

[0042] Specifically, the side wall of the docking block 6 is connected to the limiting plate 19. When the filter element is placed vertically on the positioning frame 14, the upper side wall of the filter element fits with the side wall of the limiting plate 19. At this time, the position is in place, and then the workers can directly feel whether the placement of the filter element is accurate, thereby improving efficiency.

[0043] Specifically, a plurality of clamping blocks 20 are sleeved on the outer wall of the support rod 102, and the clamping blocks 20 are fixedly connected to the side walls of the first support plate 103 and the second support plate 104. The clamping blocks 20 are fixed to the first support plate 103 and the second support plate 104 by screws, and a notch is opened on one side of the hole of the clamping block 20 for sleeved support rod 102, and a screw is engaged at the notch. By rotating the screw forward to reduce the gap of the notch, the diameter of the hole of the clamping block 20 sleeved support rod 102 is reduced, and the inner wall of the hole will be tightly clamped on the support rod 102. On the side wall of the support rod 102, the first support plate 103 and the second support plate 104 are fixed on the support rod 102. When the screw is rotated in the opposite direction, the gap of the notch becomes larger, causing the diameter of the hole of the clamping block 20 that is sleeved on the support rod 102 to become larger, and there is a gap between the hole and the side wall of the support rod 102. At this time, the first support plate 103 and the second support plate 104 can be slid on the support rod 102, and the distance between the first support plate 103 and the second support plate 104 can be adjusted to fill filter elements of different lengths, thereby making the application of the device more extensive.

[0044] Working principle: A controller and a start button are arranged outside the device. The controller is electrically connected to the first drive mechanism 9, the vibration mechanism 13, and the second drive mechanism 207, thereby controlling the operation time of each component. The start button is electrically connected to the external power supply and the controller to control the entire on-off. The circuit control diagram is shown in FIG. Fig.12 shown.

[0045] After pressing the start button, the controller controls the first drive mechanism 9, the vibration mechanism 13 and the second drive mechanism 207 to work, and controls the working time of the first drive mechanism 9, the vibration mechanism 13 and the second drive mechanism 207 (the working time is pre-edited). After working for a certain period of time, the controller controls the first drive mechanism 9, the vibration mechanism 13 and the second drive mechanism 207 to stop resetting. The controller and the start button currently have publicly used technical solutions, and their structures and principles are not the technical features of the present invention, so they are not described in detail. For example, the chip model of the controller can use STM32 or Siemens S7 series PLC controller;

[0046] The specific example usage process is: put the filter element to be installed vertically on the positioning frame 14, and then press the start button. At this time, the controller controls the first drive mechanism 9 to start, so that the output shaft of the first drive mechanism 9 pushes the lifting plate 10 and the base 12 to slide upward, so that the upper end of the filter element is pushed into the annular groove 7 of the docking block 6, so that the through hole 8 is connected with the filling chamber of the filter element (the rising process is about 0.5s), and then the controller controls the second drive mechanism 207 and the vibration mechanism 13 to start, and the output shaft of the second drive mechanism 207 rotates the turntable 204, and then opens the switch mechanism 2. At this time, the activated carbon particles inside the material tube 3 will flow into the filling chamber. The vibration mechanism 13 generates vibration when it starts, which speeds up the speed of the activated carbon particles flowing into the filling chamber, and The filled activated carbon particles are also vibrated and compacted. When the activated carbon particles inside the material pipe 3 are reduced, the lower hopper 5 will automatically introduce the activated carbon particles inside the material box 4 into the material pipe 3, so as to replenish the activated carbon particles inside the material pipe 3. When filling the activated carbon particles into the filling chamber, the filling time can be adjusted according to the actual situation and input into the controller. For example, a 40cm long filter element can be filled in about 10 seconds. After that, the controller controls the switch mechanism 2 to close and controls the vibration mechanism 13 to stop working. Then the controller controls the first drive mechanism 9 so that the output shaft of the first drive mechanism 9 pulls the lifting plate 10 and the base 12 to slide downward. At this time, the filled filter element is removed, and then the next filter element is filled with activated carbon particles according to the above steps.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
