Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology, specifically to an ultrasonic cleaning device with a wastewater filtration and treatment mechanism. Background Technology

[0002] Ultrasonic cleaning utilizes the cavitation, acceleration, and direct flow effects of ultrasound waves in liquids to directly and indirectly act on the liquid and contaminants, thereby dispersing, emulsifying, and peeling off the contaminant layer to achieve the cleaning purpose. Currently, cavitation and direct flow effects are more commonly used in ultrasonic cleaning machines.

[0003] Ultrasonic cleaning involves placing the object to be cleaned into the cleaning tank of the ultrasonic cleaning equipment, adding a suitable cleaning solution, and then using an ultrasonic generator to clean the object. After cleaning, the wastewater remaining after cleaning needs to be discharged through a drain pipe. Since the wastewater may contain dirt that has detached from the cleaned object, or fragments generated during the cleaning process (such as fragments from broken Erlenmeyer flasks or bottle caps from liquid chromatography vials), these hard residues can easily clog the drain pipe, and direct discharge can cause environmental pollution. Therefore, these residues need to be collected.

[0004] For example, Chinese patent document CN217090644U discloses an ultrasonic cleaner with a residue collection function, comprising: an ultrasonic cleaner housing; a sink located on one side of the top of the ultrasonic cleaner housing; a drain pipe fixedly installed on one side of the outer surface of the ultrasonic cleaner housing, one end of the drain pipe extending into the interior of the sink, and a branch pipe fixedly connected to the bottom of the outer surface of the drain pipe; and a filter element fixedly installed on the inner surface of the drain pipe. The ultrasonic cleaner with residue collection function provided by this utility model, by installing a filter element inside the drain pipe and connecting a branch pipe to the outside of the drain pipe on one side of the filter element, allows the filter element to filter out food residue from the water, which then enters the collector through the branch pipe, thus collecting the food residue. Once the food residue enters the collector, it cannot flow out again, preventing food residue from clogging the drain pipe and avoiding food waste.

[0005] The technical solution described in the aforementioned patent involves installing inclined filter elements on the drain pipe section. However, this method has the problem that the filter elements are difficult to clean after they become clogged, and it is also troublesome to clean the residue that has been filtered out. Summary of the Invention

[0006] The purpose of this invention is to provide an ultrasonic cleaning device with a wastewater filtration and treatment mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An ultrasonic cleaning device with a wastewater filtration treatment mechanism includes a cleaning tank and a drain pipe disposed at the bottom of the cleaning tank. A filter device is coaxially and detachably inserted into the inlet of the drain pipe, and an annular gap is left between the outer periphery of the filter device and the inner surface of the drain pipe.

[0009] The filtration device includes a reducing pipe, a bottom pipe, a limiting ring, a base plate, a rotating rod, and a cleaning brush;

[0010] The reducing pipe includes at least one set of positive conical mesh and inverted conical mesh, wherein the positive conical mesh and the inverted conical mesh are coaxially and fixedly connected.

[0011] The bottom tube is coaxially fixed to the bottom end of the reducing tube;

[0012] The limiting ring seals the top of the gap, allowing wastewater in the cleaning pool to flow into the drain pipe through the reducing pipe and the gap;

[0013] The base plate is integrally formed and disposed at the bottom end of the base tube;

[0014] The cleaning brush is disposed inside the gap, and its bristles are in contact with the outer circumferential surface of the reducing pipe. The top of the cleaning brush is circumferentially slidably connected to the limiting ring.

[0015] Part of the rotating rod is coaxial with the reducing tube, and the bottom of the part of the rotating rod that is coaxial with the reducing tube passes through the center of the base plate and is fixedly connected to the cleaning brush through a bend.

[0016] A guide block is fixedly installed on the bottom surface of the base plate. When the rotating rod drives the cleaning brush to rotate around the variable diameter tube, the rotating rod can slide over the lower surface of the guide block, causing the variable diameter tube to generate vertical extension and contraction vibration.

[0017] Preferably, the positive cone mesh and the inverted cone mesh are coaxially fixedly connected by a C-ring.

[0018] Preferably, the lower surface of the guide block includes a plane and an inclined plane;

[0019] One end of the inclined surface is connected to the lower surface of the base plate, and the other end of the inclined surface is connected to the plane.

[0020] There is a vertical distance between the plane and the lower surface of the base plate.

[0021] Preferably, a drop groove is provided on the plane.

[0022] Preferably, the bent portion of the rotating rod includes a fixedly connected horizontal bar and a third vertical bar;

[0023] The crossbar can slide along the inclined plane to the plane when rotated;

[0024] The third vertical rod is fixedly connected to the cleaning brush.

[0025] Preferably, the cleaning brush includes a brush base, a straight plate, and a spring plate;

[0026] The bristles are embedded in the surface of the straight plate;

[0027] The straight plate is connected to the groove on the side of the brush holder by the spring sheet, and the edge of the straight plate does not contact the inner circumferential surface of the groove.

[0028] Preferably, a top tube is coaxially fixed to the top end of the variable diameter tube, and the top end of the top tube is coaxially fixedly connected to the limiting ring.

[0029] Preferably, an external threaded cylinder is fixed to the lower surface of the limiting ring, and the external threaded cylinder is threadedly connected to the drain pipe;

[0030] The inner circumferential surface of the external threaded cylinder is fixed with an annular slide rail, and the top end of the cleaning brush is fixed with a slider that is slidably connected to the annular slide rail.

[0031] Preferably, the rotating rod includes a first vertical rod and a second vertical rod fixedly connected by studs;

[0032] A handle ring is fixed to the top of the first vertical rod;

[0033] The outer surface of the second vertical rod is provided with a vertically extending keyway;

[0034] The outer side of the second vertical rod is provided with a sliding sleeve, and a number of scrapers are fixed on the outer circumferential surface of the sliding sleeve. The inner circumferential surface of the sliding sleeve is provided with a positioning key that matches the keyway.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] In this invention, when the crossbar slides along the inclined plane to the flat surface, it exerts a vertically upward squeezing force on the reducing tube. This squeezing force causes the C-ring to elastically contract, changing the inclination angle of the circumferential surfaces of the positive and negative conical meshes. During this process, the bristles push out some of the residue adhering to the inner circumferential surface of the reducing tube, achieving the purpose of cleaning the inner circumferential surface of the reducing tube. Moreover, because the inclination angle of the circumferential surfaces of the positive and negative conical meshes changes, the bristles can more easily penetrate into the mesh openings of the positive and negative conical meshes, further facilitating the removal of residue from the inner circumferential surface of the reducing tube. Furthermore, since the edge of the straight plate does not contact the inner circumferential surface of the groove, and the straight plate is connected to the groove on the side of the brush holder by a spring plate, the cleaning brush rotates together with the crossbar during the process... During the process, the position and tilt angle of the straight plate and its bristles will adapt, which is more conducive to the bristles penetrating into the mesh of the positive and negative conical mesh, significantly enhancing the removal effect on the inner circumference of the variable diameter pipe. As the crossbar slides on the plane, it will pass through multiple return grooves. Each time the crossbar passes through a return groove, the positive and negative conical mesh will vibrate slightly due to the release of its own elasticity by the C-ring. This vibration is combined with the bristles. When the crossbar has completely slid across the plane, the elasticity accumulated on the C-ring will be completely released, causing the base plate to directly impact the crossbar, resulting in strong vibration of the positive and negative conical mesh. This allows the residue to fall off the inner circumference of the positive and negative conical mesh more quickly and thoroughly, making the removal of residue easier. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-11 The present invention provides a technical solution:

[0051] An ultrasonic cleaning device with a wastewater filtration and treatment mechanism includes a cleaning tank 1 and a drain pipe 11 installed at the bottom of the cleaning tank 1. The cleaning tank 1 is used to hold the object to be cleaned and the cleaning liquid. The cleaning liquid (wastewater) left after cleaning is discharged through the drain pipe 11. The above is the prior art and will not be described in detail here.

[0052] In order to filter the wastewater entering the drain pipe 11 and remove the residues in the wastewater, the present invention provides a filter device at the inlet of the drain pipe 11. The specific structure and principle of the filter device are described in detail below.

[0053] The filter device is coaxially and detachably inserted into the inlet of the drain pipe 11, and an annular gap is left between the outer periphery of the filter device and the inner surface of the drain pipe 11. Specifically, the diameter of the filter device is smaller than the inner diameter of the drain pipe 11, so that when the filter device is inserted into the drain pipe 11, an annular gap will be formed between the filter device and the inside of the drain pipe 11. Its basic working principle is: after the wastewater is filtered by the filter device, it enters the annular gap, and then enters the inside of the drain pipe 11 through the gap, and finally is discharged from the outlet of the drain pipe 11. During this process, the residues in the wastewater will accumulate inside the filter device.

[0054] The filter device includes a reducing pipe 2, a bottom pipe 3, a limiting ring 5, a base plate 6, a rotating rod 7, and a cleaning brush 8, specifically:

[0055] The reducing pipe 2 includes at least one set of positive conical mesh 21 and inverted conical mesh 22, which are coaxially and fixedly connected. The specific number of sets of positive conical mesh 21 and inverted conical mesh 22 is not specifically limited here; in this embodiment, for example... Figure 3 , Figure 5 and Figure 6 As shown, there are three sets of positive conical mesh 21 and inverted conical mesh 22. Furthermore, the positive conical mesh 21 and inverted conical mesh 22 are coaxially fixedly connected by C-rings 23. As can be seen from the figure, the C-rings 23 do not have mesh holes. Its main function is to achieve an elastic connection between the positive conical mesh 21 and inverted conical mesh 22, so that the C-rings 23 can elastically contract after the positive conical mesh 21 and inverted conical mesh 22 are compressed in the axial direction.

[0056] The bottom pipe 3 is coaxially fixed to the bottom end of the reducing pipe 2; the bottom plate 6 is integrally formed and set at the bottom end of the bottom pipe 3. As can be seen from the figure, there are no filter holes on the bottom pipe 3 and the bottom plate 6. The bottom pipe 3 and the bottom plate 6 cooperate to form a collection bucket for collecting residues in wastewater; the top pipe 4 is coaxially fixed to the top of the reducing pipe 2, and the top of the top pipe 4 is coaxially fixed to the limiting ring 5.

[0057] The limiting ring 5 is sealed at the top of the gap, allowing wastewater in the cleaning tank 1 to flow into the drain pipe 11 through the reducer 2 and the gap. Specifically, the outer diameter of the limiting ring 5 is greater than or equal to the outer diameter of the drain pipe 11. When the filter device is inserted into the drain pipe 11 and penetrates a certain distance, the limiting ring 5 will directly cover the top surface of the drain pipe 11, thus sealing the top of the gap and preventing wastewater from flowing directly into the drain pipe 11 through the top of the gap. In actual use, a corresponding rubber gasket can also be set at the contact position between the limiting ring 5 and the drain pipe 11 to improve the actual sealing performance. With this setting, the wastewater can only enter the interior of the filter device first, and then enter the interior of the gap after being filtered by the positive cone mesh 21 and the inverted cone mesh 22. Then, it flows into the drain pipe 11 from the gap and is discharged. The specific connection between the limiting ring 5 and the drain pipe 11 is as follows: an external threaded cylinder 51 is fixed on the lower surface of the limiting ring 5, and the external threaded cylinder 51 is threadedly connected to the drain pipe 11.

[0058] The cleaning brush 8 is positioned inside the gap, with its bristles 82 in contact with the outer circumferential surface of the reducing pipe 2. The top of the cleaning brush 8 is circumferentially slidably connected to the limiting ring 5. The connection between the cleaning brush 8 and the external threaded cylinder 51 is as follows: an annular slide rail 52 is fixed to the inner circumferential surface of the external threaded cylinder 51, and a slider 53 is fixed to the top of the cleaning brush 8 and slidably connected to the annular slide rail 52. Here, the annular slide rail 52 is coaxially set with the limiting ring 5. Specifically, the cleaning brush 8 can rotate around the outer circumferential surface of the reducing pipe 2, thereby using its bristles 82 to brush away the residue adhering to the inner circumferential surface of the reducing pipe 2 from the outside to the inside. The principle is that the diameter of the bristles 82 is smaller than the mesh openings on the positive cone mesh 21 and the inverted cone mesh 22, so that the bristles 82 can partially penetrate into the interior of the reducing pipe 2 during rotation, thereby pushing out the residue adhering to the inner circumferential surface of the reducing pipe 2.

[0059] Part of the rotating rod 7 is coaxial with the reducing pipe 2, and the bottom of the part of the rotating rod 7 that is coaxial with the reducing pipe 2 (that is, the part of the rotating rod 7 mentioned above) passes through the center of the base plate 6 and is fixedly connected to the cleaning brush 8 through the bending part; by rotating the rotating rod 7, the cleaning brush 8 can be driven to rotate around the outer circumference of the reducing pipe 2.

[0060] A guide block 10 is fixedly installed on the bottom surface of the base plate 6. When the rotating rod 7 drives the cleaning brush 8 to rotate around the variable diameter tube 2, the rotating rod 7 can slide over the lower surface of the guide block 10, causing the variable diameter tube 2 to generate vertical extension and contraction vibration. The number of guide blocks 10 is not specifically limited here. For example, as shown in the figure, the number of guide blocks 10 can be set to four, and the four guide blocks 10 are arranged equidistantly around the center of the base plate 6.

[0061] Furthermore, the lower surface of the guide block 10 includes a plane 101 and an inclined plane 102; one end of the inclined plane 102 is connected to the lower surface of the base plate 6, and the other end of the inclined plane 102 is connected to the plane 101; there is a vertical distance between the plane 101 and the lower surface of the base plate 6, and a return groove 103 is provided on the plane 101. The setting of the return groove 103 allows the crossbar 73 to generate a slight vibration during the sliding process on the plane 101, which is conducive to shaking off the residues adhering to the inner surface of the reducer 2.

[0062] The bent portion of the rotating rod 7 includes a horizontal rod 73 and a third vertical rod 74 that are fixedly connected; the horizontal rod 73 can slide along the inclined plane 102 to the plane 101 when rotating; the third vertical rod 74 is fixedly connected to the cleaning brush 8.

[0063] The rotating rod 7 includes a first vertical rod 71 and a second vertical rod 72 fixedly connected by a stud. The first vertical rod 71 and the second vertical rod 72 are connected by a stud, and the helical direction of the stud needs to maintain the following state with the rotation direction of the horizontal rod 73: when the horizontal rod 73 is rotated, the first vertical rod 71 and the second vertical rod 72 will gradually tighten, thereby avoiding the first vertical rod 71 and the second vertical rod 72 from loosening and separating when the horizontal rod 73 is rotated; a handle ring 75 is fixed to the top of the first vertical rod 71; a vertically extending keyway 721 is opened on the outer surface of the second vertical rod 72; a sliding sleeve 91 is slidably sleeved on the outer side of the second vertical rod 72, and a number of scrapers 9 are fixed on the outer circumferential surface of the sliding sleeve 91. A positioning key 92 adapted to the keyway 721 is provided on the inner circumferential surface of the sliding sleeve 91; wherein, the scraper 9 can rotate with the second vertical rod 72 in the cooperation of the keyway 721 and the positioning key 92, which is conducive to scraping the residue deposited on the bottom plate 6.

[0064] The cleaning brush 8 includes a brush base 81, a straight plate 83, and a spring plate 84; the bristles 82 are embedded in the surface of the straight plate 83; the straight plate 83 is connected to the groove 811 opened on the side of the brush base 81 through the spring plate 84, and the edge of the straight plate 83 does not contact the inner circumferential surface of the groove 811, so that the bristles 82 can move in all directions during the rotation of the cleaning brush 8, which makes it easier to push out the residues adhering to the inner surface of the reducing pipe 2.

[0065] The basic working principle of the above scheme is as follows: First, the entire filter device is tightened and installed at the inlet of the drain pipe 11 using the external threaded cylinder 51; then, the object to be cleaned and the cleaning liquid are placed into the cleaning tank 1, and the ultrasonic cleaning equipment is started to clean the object. After cleaning, the cleaned object is taken out, and then the valve of the drain pipe 11 is opened to drain the water. At this time, the filter device will collect the residue in the wastewater. The specific filtration process is as follows: The wastewater first enters the interior of the reducer 2 through the inlet at the top of the top pipe 4, and after being filtered by the positive cone mesh 21 and the inverted cone mesh 22 that make up the reducer 2, it flows into the drain pipe 11 through the gap and through the drain outlet of the drain pipe 11. During the discharge process, the residues in the wastewater will increasingly adsorb or adhere to the inner circumferential surfaces of the positive cone mesh 21 and the inverted cone mesh 22, causing a decrease in the filtration efficiency of the reducer 2, or even complete blockage of the reducer 2. At this time, the first vertical rod 71, the second vertical rod 72, the horizontal rod 73, and the third vertical rod 74 are directly turned by using the handle ring 75, causing the first vertical rod 71 and the second vertical rod 72 to rotate around their own axes, which in turn drives the horizontal rod 73 and the third vertical rod 74 to rotate around the axes of the first vertical rod 71 and the second vertical rod 72. On the one hand, the rotation of the horizontal rod 73 will cause it to slide along the inclined plane 102 onto the plane 101. Since the top of the cleaning brush 8 is connected to the annular slide rail 52 and the slider 53, the cleaning brush 8 is connected to the plane 101. The limiting ring 5 is slidably connected, so the vertical positions of the cleaning brush 8 and the third vertical rod 74 remain unchanged. That is, the vertical position of the horizontal rod 73 (the horizontal rod 73 and the third vertical rod 74 are fixedly connected) remains unchanged. Therefore, when the horizontal rod 73 slides along the inclined plane 102 to the plane 101, the horizontal rod 73 will exert a vertically upward squeezing force on the reducing pipe 2. This squeezing force will cause the C-ring 23 to elastically contract, and the inclination angle of the circumferential surfaces of the positive cone mesh 21 and the inverted cone mesh 22 will change. During this process, the bristles 82 will push out some of the residue adhering to the inner circumferential surface of the reducing pipe 2, thereby achieving the purpose of cleaning the inner circumferential surface of the reducing pipe 2. Moreover, due to the inclination angle of the circumferential surfaces of the positive cone mesh 21 and the inverted cone mesh 22, the reducing pipe 2 will elastically contract. The change in the angle of inclination makes it easier for the bristles 82 to penetrate the mesh openings on the positive conical mesh 21 and the inverted conical mesh 22, which is more conducive to ejecting the residue on the inner circumferential surface of the variable diameter tube 2. Furthermore, since the edge of the straight plate 83 does not contact the inner circumferential surface of the groove 811, and the straight plate 83 is connected to the groove 811 on the side of the brush holder 81 by the spring plate 84, the position, inclination angle, etc. of the straight plate 83 and the bristles 82 on it will change adaptively during the rotation of the cleaning brush 8 along with the crossbar 73. This is more conducive to the bristles 82 penetrating the mesh openings on the positive conical mesh 21 and the inverted conical mesh 22, which significantly enhances the ejection effect of the residue on the inner circumferential surface of the variable diameter tube 2.As the crossbar 73 slides on the plane 101, it passes through multiple return grooves 103. Each time the crossbar 73 passes through a groove 103, the conical mesh 21 and the inverted conical mesh 22 vibrate slightly due to the release of elasticity from the C-ring 23. This vibration, combined with the bristles 82, allows residue to fall off the inner circumference of the conical mesh 21 and the inverted conical mesh 22 more quickly and thoroughly. When the crossbar 73 has completely slid across the plane 101, the elasticity accumulated on the C-ring 23 is completely released, causing the base plate 6 to directly impact the crossbar 73. This causes a strong vibration in the conical mesh 21 and the inverted conical mesh 22, allowing residue to fall off the inner circumference of the conical mesh 21 and the inverted conical mesh 22 more quickly and thoroughly.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
