Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cleaning, in particular to an ultrasonic cleaning device with a wastewater filtering and processing mechanism. Background Art

[0002] Ultrasonic cleaning uses the cavitation effect, acceleration effect and straight flow effect of ultrasound in liquid to directly and indirectly affect liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning. Among the ultrasonic cleaning machines currently used, cavitation and straight flow effects are more widely used.

[0003] The method of ultrasonic cleaning is to place the object to be cleaned in the cleaning tank of the ultrasonic cleaning equipment, add appropriate cleaning liquid into the cleaning tank, and then cooperate with the ultrasonic generating unit to clean the object to be cleaned. After the cleaning is completed, the wastewater left after the cleaning liquid is cleaned needs to be discharged through the drain pipe. Since there may be dirt that falls off from the object to be cleaned in the wastewater, or fragments of the object to be cleaned that are broken during the cleaning process (such as fragments caused by the breakage of the triangular flask during the cleaning process or the bottle cap of a small liquid phase bottle), this part of the hard residue is easy to cause the drain pipe to be blocked, and directly discharging it is also easy to cause environmental pollution and other problems, so these residues need to be collected.

[0004] For example, a Chinese patent document with the announcement number CN217090644U discloses an ultrasonic cleaning machine with a residue collection function, comprising: an ultrasonic cleaning machine housing; a dishwashing tank, the dishwashing tank is opened on one side of the top of the ultrasonic cleaning machine housing; a drain pipe, the drain pipe is fixedly installed on one side of the outer surface of the ultrasonic cleaning machine housing, one end of the drain pipe extends to the inside of the dishwashing tank, and a branch pipe is fixedly connected to the bottom of the outer surface of the drain pipe; a filter, the filter is fixedly installed on the inner surface of the drain pipe. The ultrasonic cleaning machine with a residue collection function provided by the utility model, by installing a filter in the drain pipe, and connecting a branch pipe outside the drain pipe on one side of the filter, the filter can filter food residues in the water, and enter the collector through the branch pipe, so that the food residues are collected, and the food residues cannot flow out after entering the collector, so as to avoid the food residues from clogging the drain pipe and also avoid food waste.

[0005] The technical solution described in the above patent is to set an inclined filter on the pipe section of the drainage pipe, but the problem with this method is that it is difficult to clean the filter after it is blocked, and it is troublesome to clean the filtered residue.

[0016] A guide block is fixedly arranged on the bottom surface of the bottom plate. When the rotating rod drives the cleaning brush to rotate around the reducer, the rotating rod can slide over the lower surface of the guide block to cause the reducer to generate vertical telescopic vibration.

[0017] Preferably, the forward cone cylinder net and the inverted cone cylinder net are coaxially fixedly connected via a C-shaped ring.

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

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

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

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

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] When the cross bar of the present invention slides along the inclined surface to the plane, the cross bar will generate a vertical upward extrusion force on the reducer, and the extrusion force will cause the C-shaped ring to elastically contract, and the inclination angles of the circumferences of the positive cone cylinder net and the inverted cone cylinder net will change. In this process, the bristles will push out a part of the residues adhering to the inner circumference of the reducer, so as to achieve the purpose of cleaning the inner circumference of the reducer. Moreover, since the inclination angles of the circumferences of the positive cone cylinder net and the inverted cone cylinder net are changed, the bristles can more easily penetrate into the inside of the mesh holes on the positive cone cylinder net and the inverted cone cylinder net, which is more conducive to pushing out the residues on the inner circumference of the reducer. Furthermore, since the edge of the straight plate does not contact the inner circumference of the groove, and the straight plate is connected to the groove opened on the side of the brush seat by a spring sheet, during the process of the cleaning brush rotating together with the cross bar. In the process, the position, inclination angle, etc. of the straight plate and the bristles thereon will produce adaptive changes, which is more conducive to the bristles penetrating into the mesh holes on the positive cone cylinder net and the inverted cone cylinder net, and significantly enhances the ejection effect of the residue on the inner circumference of the reducer; when the cross bar slides on the plane, the cross bar will pass through multiple return grooves, and each time the cross bar passes through a return groove, the positive cone cylinder net and the inverted cone cylinder net will produce a small vibration due to the C-shaped ring releasing its own elastic force, and the vibration cooperates with the bristles; and when the cross bar completely slides across the plane, the elastic force gathered on the C-shaped ring will be completely released, so that the bottom plate directly hits the cross bar, causing the positive cone cylinder net and the inverted cone cylinder net to vibrate strongly, so that the residue can fall off from the inner circumference of the positive cone cylinder net and the inverted cone cylinder net more quickly and thoroughly, and the difficulty of cleaning the residue is low.

DETAILED DESCRIPTION

[0049] 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.

[0050] See also Figure 1-Figure 11 , the present invention provides a technical solution:

[0051] An ultrasonic cleaning device with a wastewater filtering and processing mechanism comprises a cleaning pool 1 and a drain pipe 11 arranged at the bottom of the cleaning pool 1. The cleaning pool 1 is used to hold objects to be cleaned and cleaning liquid. The cleaning liquid (wastewater) left after cleaning is completed is discharged through the drain pipe 11. The above is the prior art and will not be repeated here.

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

[0053] The filter device is coaxially and detachably plugged into the water 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 plugged into the drain pipe 11, an annular gap is formed between the filter device and the drain pipe 11; its basic working principle is: wastewater enters the annular gap after being filtered by the filter device, and then enters the drain pipe 11 from the gap, and is finally discharged from the water outlet of the drain pipe 11. In this process, residues in the wastewater will gather inside the filter device.

[0054] The filtering device comprises a reducing pipe 2, a bottom pipe 3, a limiting ring 5, a bottom plate 6, a rotating rod 7 and a cleaning brush 8. Specifically:

[0055] The reducer 2 includes at least one group of positive cone cylinder nets 21 and inverted cone cylinder nets 22, and the positive cone cylinder nets 21 and the inverted cone cylinder nets 22 are coaxially fixedly connected; the specific number of groups of the positive cone cylinder nets 21 and the inverted cone cylinder nets 22 is not specifically limited here. In this embodiment, Figure 3 , Figure 5 and Figure 6 As shown, there are three groups of positive cone cylinder nets 21 and inverted cone cylinder nets 22. Furthermore, the positive cone cylinder nets 21 and the inverted cone cylinder nets 22 are coaxially fixedly connected by a C-shaped ring 23. It can be seen from the figure that no mesh is set on the C-shaped ring 23, and its main function is to achieve elastic connection between the positive cone cylinder nets 21 and the inverted cone cylinder nets 22, so that the C-shaped ring 23 can elastically shrink after the positive cone cylinder nets 21 and the inverted cone cylinder nets 22 are squeezed in the axial direction.

[0056] The bottom tube 3 is coaxially fixed to the bottom end of the reducer 2; the bottom plate 6 is integrally formed and arranged at the bottom end of the bottom tube 3. As can be seen from the figure, no filter holes are arranged on the bottom tube 3 and the bottom plate 6. The bottom tube 3 and the bottom plate 6 cooperate to form a collecting bucket for collecting residues in wastewater; the top end of the reducer 2 is coaxially fixed with a top tube 4, and the top end of the top tube 4 is coaxially fixedly connected with the limit ring 5.

[0057] The limiting ring 5 is sealed at the top of the gap, so that the waste water in the cleaning pool 1 flows 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 to achieve the blocking of the top of the gap to prevent the waste water from flowing directly into the drain pipe 11 through the top of the gap. In actual use, a corresponding rubber gasket can also be provided at the contact position between the limiting ring 5 and the drain pipe 11 to improve the actual sealing performance; after such a setting, the waste water can only enter the interior of the filtering device first, and then enter the interior of the gap after being filtered by the positive cone net 21 and the inverted cone net 22, and then flow into the interior of the drain pipe 11 from the gap and be discharged; the specific connection method between the limiting ring 5 and the drain pipe 11 is: 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 arranged inside the gap, and its bristles 82 are in contact with the outer circumferential surface of the reducer 2, and the top of the cleaning brush 8 is circumferentially slidably connected to the limiting ring 5; the connection method of the cleaning brush 8 and the external threaded tube 51 is: an annular slide rail 52 is fixed to the inner circumferential surface of the external threaded tube 51, and a slider 53 slidably connected to the annular slide rail 52 is fixed to the top of the cleaning brush 8, and the annular slide rail 52 here is coaxially arranged with the limiting ring 5; specifically, the cleaning brush 8 can rotate around the outer circumferential surface of the reducer 2, so that the bristles 82 thereon can be used to brush off the residues adhering to the inner circumferential surface of the reducer 2 from the outside to the inside, and the principle is that the diameter of the bristles 82 is smaller than the mesh holes on the positive cone net 21 and the inverted cone net 22, so that the bristles 82 can partially penetrate into the interior of the reducer 2 during rotation, thereby ejecting the residues adhering to the inner circumferential surface of the reducer 2.

[0059] Part of the rotating rod 7 is coaxial with the reducer 2, and the bottom of the part of the rotating rod 7 coaxial with the reducer 2 (that is, the above-mentioned part of the rotating rod 7) passes through the center of the bottom 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 reducer 2.

[0060] A guide block 10 is fixedly provided on the bottom surface of the base plate 6. When the rotating rod 7 drives the cleaning brush 8 to rotate around the reducer 2, the rotating rod 7 can slide over the lower surface of the guide block 10, causing the reducer 2 to produce vertical telescopic 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 surface 102; one end of the inclined surface 102 is connected to the lower surface of the base plate 6, and the other end of the inclined surface 102 is connected to the plane 101; there is a distance between the plane 101 and the lower surface of the base plate 6 in the vertical direction, and a return groove 103 is provided on the plane 101. The setting of the return groove 103 allows the cross bar 73 to further generate slight vibrations 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 cross bar 73 and a third vertical bar 74 which are fixedly connected; the cross bar 73 can slide along the inclined surface 102 to the plane 101 when rotating; the third vertical bar 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 screw thread direction of the stud and the rotation direction of the cross rod 73 need to maintain the following state: when the cross rod 73 is rotated, the first vertical rod 71 and the second vertical rod 72 will gradually tighten, so as to avoid the first vertical rod 71 and the second vertical rod 72 from loosening and separating when the cross rod 73 is rotated; a handle ring 75 is fixed to the top of the first vertical rod 71; a vertically extending key groove 721 is provided on the outer surface of the second vertical rod 72; a sliding sleeve 91 is provided on the outer sliding sleeve of the second vertical rod 72, and a plurality of scrapers 9 are fixed on the outer peripheral surface of the sliding sleeve 91, and a positioning key 92 matched with the key groove 721 is provided on the inner peripheral surface of the sliding sleeve 91; wherein, the scraper 9 can rotate with the second vertical rod 72 in cooperation with the key groove 721 and the positioning key 92, so as to scrape the residue deposited on the bottom plate 6.

[0064] The cleaning brush 8 includes a brush holder 81, a straight plate 83 and a spring sheet 84; the bristles 82 are planted on the surface of the straight plate 83; the straight plate 83 is connected to a groove 811 opened on the side of the brush holder 81 through the spring sheet 84, and the edge of the straight plate 83 does not contact the inner circumference of the groove 811, so that the bristles 82 can move in all directions during the rotation of the cleaning brush 8, so as to facilitate the ejection of residues adhering to the inner surface of the reducer 2.

[0065] The basic working principle of the above scheme is: first, use the external threaded cylinder 51 to tighten the entire filtering device and install it at the water inlet position of the drain pipe 11; then the objects to be cleaned and the cleaning liquid can be placed in the cleaning tank 1, and the ultrasonic cleaning equipment is started to clean the objects to be cleaned. After the cleaning is completed, the cleaned objects are fished out, and then the valve of the drain pipe 11 is opened to drain the water. At this time, the filtering device will collect the residues in the wastewater. The specific filtering process is as follows: the wastewater first enters the interior of the reducer 2 through the water inlet at the top of the top pipe 4, and then flows into the drain pipe 11 through the gap after being filtered by the positive cone cylinder net 21 and the inverted cone cylinder net 22 that constitute the reducer 2, and then flows into the drain pipe 11 through the gap, and passes through the drain outlet of the drain pipe 11 The filter element 73 is a filter element which is used to filter the filter element 21 and filter 22. The filter element 73 is a filter element which is used to filter the filter element 21 and filter 22. The filter element 73 is a filter element which is used to filter the filter element 21 and filter 22. The limiting ring 5 is slidably connected, so the vertical position of the cleaning brush 8 and the third vertical rod 74 will remain unchanged, that is, the vertical position of the cross bar 73 (the cross bar 73 and the third vertical rod 74 are fixedly connected) will remain unchanged, so that when the cross bar 73 slides along the inclined surface 102 to the plane 101, the cross bar 73 will produce a vertical upward extrusion force on the reducer 2, and the extrusion force will cause the C-shaped ring 23 to elastically contract, and the inclination angle of the circumference of the positive cone net 21 and the inverted cone net 22 will change. In this process, the bristles 82 will push out a part of the residue adhering to the inner circumference of the reducer 2, so as to achieve the purpose of cleaning the inner circumference of the reducer 2. In addition, due to the inclination angle of the circumference of the positive cone net 21 and the inverted cone net 22 The change in the bevel angle makes it easier for the bristles 82 to penetrate into the mesh holes on the positive cone cylinder net 21 and the inverted cone cylinder net 22, which is more conducive to ejecting the residues on the inner circumference of the reducer 2; further, since the edge of the straight plate 83 does not contact the inner circumference of the groove 811, and the straight plate 83 is connected to the groove 811 opened on the side of the brush holder 81 through the spring sheet 84, the position, inclination angle, etc. of the straight plate 83 and the bristles 82 thereon will change adaptively during the rotation of the cleaning brush 8 following the cross bar 73, which is more conducive to the bristles 82 penetrating into the mesh holes on the positive cone cylinder net 21 and the inverted cone cylinder net 22, and significantly enhancing the ejection effect of the residues on the inner circumference of the reducer 2;When the cross bar 73 slides on the plane 101, the cross bar 73 will pass through a plurality of return grooves 103. Each time the cross bar 73 passes through a return groove 103, the positive cone cylinder net 21 and the inverted cone cylinder net 22 will generate a small vibration due to the release of the elastic force of the C-shaped ring 23. The vibration cooperates with the bristles 82 to make the residue fall off from the inner circumference of the positive cone cylinder net 21 and the inverted cone cylinder net 22 more quickly and thoroughly. When the cross bar 73 completely slides over the plane 101, the elastic force gathered on the C-shaped ring 23 will be completely released, so that the bottom plate 6 directly hits the cross bar 73, so that the positive cone cylinder net 21 and the inverted cone cylinder net 22 generate strong vibrations, so that the residue can fall off from the inner circumference of the positive cone cylinder net 21 and the inverted cone cylinder net 22 more quickly and thoroughly.

[0066] 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.
