Description

Technical Field

[0001] This utility model relates to the field of circulating mixer technology, specifically a float-type circulating mixer. Background Technology

[0002] In order to improve water quality and enhance the self-purification capacity of water bodies, wastewater treatment technology has been widely used, and the float-type circulating mixer, as a highly efficient water treatment device, has emerged as a result.

[0003] The float-type circulating mixer can float on the water surface, making it convenient for workers to install and maintain. The float-type circulating mixer can also use a motor to drive the composite impeller to rotate at high speed, which creates negative pressure on the back of the composite impeller. Under the combined action of negative pressure and positive pressure generated by the blower, air is sheared, stirred and dissolved in the water, increasing the oxygen content in the water, thereby promoting the growth and reproduction of microorganisms in the water and accelerating the degradation of pollutants.

[0004] Some existing float-type circulating mixers have excellent mixing capabilities and can purify and repair water. However, most of them use bolts to install the motor on the mounting bracket on the float. Over time, the bolts will rust, making it difficult and inefficient to disassemble and repair the motor. This wastes a lot of time for the staff and causes unnecessary trouble. Furthermore, the staff cannot perform maintenance work if they forget to bring their tools, which is a significant limitation. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a float-type circulating mixer to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a float-type circulating mixer, comprising a linkage shaft, a motor mounted on the top end of the linkage shaft, a reducer mounted on the bottom end of the linkage shaft, a rotating shaft mounted on the bottom end of the reducer, a compound impeller mounted on the bottom end of the rotating shaft, a float mounted on the outside of the motor, and portable mounting components symmetrically mounted on both sides of the float. Each portable mounting component includes a limiting sleeve, two limiting sleeves are engaged on both sides of the float, and two limiting slots are formed through both sides of the limiting sleeves. A long locking block is installed in the limiting slot. One end of the long locking block is engaged with a limiting slot. A square sliding hole is opened on one side of the long locking block. A slider is slidably arranged in the square sliding hole. A tension spring is connected to the bottom of the square sliding hole. The top of the tension spring is connected to the slider. A fixed shaft is fixedly installed on the top side of the slider. A limiting block is movably installed on the outside of the fixed shaft. The limiting block is engaged with another limiting slot. A square limiting plate is also fixedly installed on the outside of the fixed shaft. The square limiting plate is located above and in contact with the limiting block.

[0007] By adopting the above technical solution, a limiting sleeve is used to limit the vertical movement of the pontoon connection, and a limiting slot and a long locking block are used to limit the horizontal and forward / backward movement of the pontoon connection, thereby completely fixing the two pontoons in place. A square sliding hole, a slider, a tension spring, a fixed shaft, a limiting block, a handle, and a square limiting plate are used to limit the limiting sleeve and the long locking block. Specifically, the long locking block is inserted into the limiting slot on the bottom side of the limiting sleeve, passing through the pontoon connection until the bottom end of the long locking block is engaged in the limiting slot on the bottom side of the limiting sleeve. At this point, pulling the handle moves the slider, fixed shaft, limiting block, and square limiting plate upwards until the bottom side of the limiting block is flush with the top of the limiting sleeve. With the sides flush, rotate the limiting block. Under the constraint of the square limiting plate, the limiting block can only rotate and cannot slide up or down. Rotate the limiting block 90 degrees and slowly release the pull on the handle. Under the tension of the spring, the limiting block will slowly descend until it engages in the limiting slot on the top side of the limiting sleeve plate, thus locking the limiting sleeve plate and the long locking block. Using portable installation components simplifies the installation and disassembly of the motor and float, improving efficiency and reducing the time spent by workers. This saves workers a lot of trouble, and the entire process requires no tools; disassembly and installation can be completed manually, making it very convenient.

[0008] The present invention is further configured such that multiple elongated limiting holes are provided on the four sides of the square sliding hole, and multiple elongated protrusions that cooperate with the elongated limiting holes are provided on the four sides of the slider.

[0009] By adopting the above technical solution, the use of elongated limiting holes and elongated protrusions enhances the sliding limiting effect on the slider, making the slider slide more smoothly within the square sliding hole.

[0010] The present invention is further configured such that the float is composed of two snap-fit ​​floats, one side of the snap-fit ​​float is provided with two parallel clamping plates and a motor clamping groove, one side of the clamping plate is provided with a through mounting hole, and the long strip locking block passes through the mounting hole.

[0011] By adopting the above technical solution, the use of a clamping plate allows the two snap-fit ​​floats to form a front and rear limit when they are assembled and snapped together.

[0012] The present invention is further configured such that a plurality of limiting protrusions and a motor limiting plate are fixedly provided on one side of the motor slot, an annular plate is fixedly installed on the outer side of the motor, a card hole adapted to the annular plate is opened on one side of the motor slot, and a temperature guiding plate is provided on one side of the carding float.

[0013] By adopting the above technical solution, the motor is completely fixed and limited using an annular plate, motor slot, limiting protrusion, motor limiting plate and locking hole. The motor slot provides support for the motor, the motor limiting plate limits the upper and lower movement of the motor, the limiting protrusion further strengthens the limiting of the motor, and the annular plate and locking hole completely fix the motor.

[0014] The present invention is further configured such that the annular plate contacts the limiting protrusion and the motor limiting plate, and the temperature-conducting plate contacts the annular plate through the through hole.

[0015] By adopting the above technical solution, the heat generated by the motor can be transferred to the heat-conducting plate through the limiting protrusion, the motor limiting plate and the annular plate. The heat-conducting plate then introduces the heat into the water to achieve a stronger heat dissipation effect on the motor.

[0016] The present invention is further provided that a handle is installed at the top end of the fixed shaft.

[0017] By adopting the above technical solution, it is easier for staff to apply force to the fixed shaft, thereby easily moving the limit block upwards, and then rotating it to lock or unlock the portable installation component.

[0018] The present invention is further configured such that the annular plate, the limiting protrusion, the motor limiting plate and the temperature conducting plate are all made of aluminum alloy with good thermal conductivity.

[0019] By adopting the above technical solution, the heat generated by the motor can be better transferred into the water through the heat conduction plate, thereby further enhancing the heat dissipation of the motor.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model achieves left-right and front-back limiting at the connection point of the pontoons by setting a limiting slot and a long locking block, thereby completely limiting and fixing the two pontoons. Furthermore, by stretching the limiting slot, rotating it 90 degrees, and then lowering it, the long locking block itself is locked. This utility model simplifies the installation and disassembly between the motor and the pontoons by using the above-mentioned components, improves the efficiency of installation and disassembly, reduces the time spent by workers on installation and disassembly, saves workers a lot of trouble, and requires no tools at all. The disassembly and installation work can be completed manually, which is very convenient.

[0022] 2. This utility model, by setting an annular plate, a limiting protrusion, a motor limiting plate, and a temperature-conducting plate, allows the heat generated by the motor to be transferred to the temperature-conducting plate through the limiting protrusion, the motor limiting plate, and the annular plate. The temperature-conducting plate then guides the heat into the water, thereby achieving an enhanced heat dissipation effect for the motor. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1

[0035] A type of float-type circulating mixer, such as Figure 1 - Figure 8As shown, the system includes a linkage shaft 1, a motor 2 connected to the top of the linkage shaft 1, a reducer 3 connected to the bottom of the linkage shaft 1, a rotating shaft 4 connected to the bottom of the reducer 3, a compound impeller 7 connected to the bottom of the rotating shaft 4, and a float 5 mounted on the outside of the motor 2. The float 5 is composed of two snap-fit ​​floats 51. One side of each snap-fit ​​float 51 has two parallel clamping plates 52 and a motor slot 53. One side of each clamping plate 52 has a through-hole 54. Portable mounting components 6 are symmetrically mounted on both sides of the float 5. Each portable mounting component 6 includes a limiting sleeve 61. Two limiting sleeves 61 are snapped onto both sides of the float 5, and two limiting sleeves 61 have through-holes on both sides. Two locking slots 62 are equipped with elongated locking blocks 63, which pass through mounting holes 54. One end of each elongated locking block 63 is engaged with one of the locking slots 62. A square sliding hole 64 is provided on one side of each elongated locking block 63, and a slider 65 is slidably mounted within the square sliding hole 64. A tension spring 66 is connected to the bottom of the square sliding hole 64, and the top of the tension spring 66 is connected to the slider 65. A fixed shaft 67 is fixedly mounted on the top side of the slider 65. A limiting block 68 is movably mounted on the outer side of the fixed shaft 67, and the limiting block 68 is engaged with another locking slot 62. A handle 69 is installed on the top of the fixed shaft 67, making it easier for workers to operate the fixed shaft 67. The force is applied, which easily moves the limiting block 68 upward, and then it can be rotated to lock or unlock the portable installation component 6. A square limiting plate 610 is also fixedly installed on the outside of the fixed shaft 67. The square limiting plate 610 is located above and in contact with the limiting block 68. The clamping plate 52 allows the two snap-fit ​​floats 51 to form a front and rear limit when they are assembled and snapped together. The limiting sleeve 61 provides the upper and lower limit for the two snap-fit ​​floats 51. The limiting slot 62, the long locking block 63, and the mounting hole 54 provide the left and right limit for the two snap-fit ​​floats 51, thus completely limiting and fixing the two snap-fit ​​floats 51. The square sliding hole 64 provides the limit. The system comprises a slider 65, a tension spring 66, a fixed shaft 67, a limiting block 68, a handle 69, and a square limiting plate 610. This allows the limiting sleeve 61 and the long locking block 63 to be positioned. Specifically, the long locking block 63 is inserted into the limiting slot 62 on the bottom side of the limiting sleeve 61, passing through the mounting holes 54 on both plates 52 until its bottom end is engaged in the limiting slot 62 on the bottom side of the limiting sleeve 61. Pulling the handle 69 then moves the slider 65, fixed shaft 67, limiting block 68, and square limiting plate 610 upwards until the bottom side of the limiting block 68 is flush with the top side of the limiting sleeve 61. At this point, rotating the limiting block 68, which can only rotate and cannot slide up or down due to the limiting effect of the square limiting plate 610, allows it to continue rotating.Rotate the limiting block 68 ninety degrees and slowly release the tension on the handle 69. Under the tension of the tension spring 66, the limiting block 68 will slowly descend until it engages with the limiting slot 62 on the top side of the limiting sleeve 61, thus locking the limiting sleeve 61 and the long locking block 63. The portable installation component 6 simplifies the installation and disassembly between the motor 2 and the float 5, improving installation and disassembly efficiency and reducing the time spent by workers on installation and disassembly. This design saves workers a lot of trouble, and the entire disassembly and installation can be completed manually without any tools, making it very convenient. The square sliding hole 64 has multiple elongated limiting holes 611 on its four sides, and the slider 65 has multiple elongated protrusions 612 on its four sides that mate with the elongated limiting holes 611. The elongated limiting holes 611 and the elongated protrusions 612 enhance the sliding limiting effect on the slider 65, making the slider 65 slide more smoothly within the square sliding hole 64.

[0036] Please see Figure 2 - Figure 4 The motor slot 53 has multiple limiting protrusions 55 and a motor limiting plate 56 fixedly provided on one side. An annular plate 21 is fixedly installed on the outer side of the motor 2. A locking hole 57 adapted to the annular plate 21 is provided on one side of the motor slot 53. A temperature-conducting plate 58 is provided on one side of the hook-and-hold float 51. The annular plate 21 contacts the limiting protrusions 55 and the motor limiting plate 56. The temperature-conducting plate 58 passes through the locking hole 57 and contacts the annular plate 21. By providing the annular plate 21, motor slot 53, limiting protrusions 55, motor limiting plate 56, and locking hole 57, the motor 2 is completely limited and fixed. The motor slot 53 provides support for the motor 2, and the motor limiting plate 56... The upper and lower limits of motor 2 are now defined. The limiting protrusion 55 is used to further strengthen the limiting of motor 2. The annular plate 21 and the locking hole 57 completely fix motor 2. The heat generated by motor 2 can be transferred to the heat-conducting plate 58 through the limiting protrusion 55, motor limiting locking plate 56 and annular plate 21. The heat-conducting plate 58 then introduces the heat into the water to achieve a better heat dissipation effect for motor 2. The annular plate 21, limiting protrusion 55, motor limiting locking plate 56 and heat-conducting plate 58 are all made of aluminum alloy with good thermal conductivity, so that the heat generated by motor 2 can be better introduced into the water through the heat-conducting plate 58 to further enhance the heat dissipation of motor 2.

[0037] Example 2

[0038] A type of float-type circulating mixer, such as Figure 7As shown, the technical solution and parts of this embodiment are basically the same as those of Embodiment 1. The technically similar parts will not be described again here. The difference is that the two clamping plates 52 can be arranged crosswise on one side of the annular plate 21. By arranging the clamping plates 52 crosswise instead of parallel, the two clamping floats 51 can play a role in limiting the upper and lower positions when they are clamped, thereby strengthening the connection between the two clamping floats 51.

[0039] Example 3

[0040] A type of float-type circulating mixer, such as Figure 7 and Figure 8 As shown, the technical solution and components of this embodiment are basically the same as those of Embodiment 1. The technically identical parts will not be repeated here. The difference lies in that a slot 59 is provided on one side of the card plate 52, and two symmetrical slots 510 are provided on the top side of the card plate 52. A card block 613 is engaged in the slot 59. A circular sliding hole 614 is provided on the top side of the card block 613. A sliding rod 615 is slidably disposed within the circular sliding hole 614. A square sliding hole 64 is connected to the bottom of the circular sliding hole 614, and the top of the square sliding hole 64 is connected to the sliding rod 615. The connection is achieved by fixing a buckle 616 on the outer side of the slide rod 615. Simply pull the buckle 616 so that the height of the bottom side of the buckle 616 is flush with the height of the top side of the slot 510, and then snap the locking block 613 into the slot 59. Release the buckle 616, and the buckle 616 will be locked to the square limiting plate 610 under the pull of the square sliding hole 64 and driven by the slide rod 615. This embodiment makes the installation and disassembly between the motor 2 and the float 5 faster and more convenient, and further simplifies the locking and unlocking process of the portable installation component 6.

[0041] The working principle of this utility model is as follows: When the device needs to be installed and used, the motor 2, linkage shaft 1, reducer 3, rotating shaft 4, and compound impeller 7 have already been installed in advance. At this time, it is only necessary to align the clamping plates 52 on the two clamping floats 51 with each other, align the motor 2 with the motor clamping groove 53 on the clamping float 51, and align the annular plate 21 with the clamping hole 57 on the motor clamping groove 53, thereby completing the initial connection between the motor 2 and the float 5. Then, the two limiting sleeves 61 are clamped to both sides of the float 5 formed by the connection of the two clamping floats 51, and then a long strip locking block 63 is placed from one of the limiting sleeves. Insert the limiting slot 62 on the bottom side of the sleeve 61, and then pass through the mounting holes 54 on the two locking plates 52 in sequence until the bottom end of the long locking block 63 is engaged in the limiting slot 62 on the bottom side of the limiting sleeve 61. At this time, pull the handle 69 to move the slider 65, the fixed shaft 67, the limiting block 68 and the square limiting plate 610 upward until the bottom side of the limiting block 68 is flush with the top side of the limiting sleeve 61. At this time, rotate the limiting block 68. Under the limiting action of the square limiting plate 610, the limiting block 68 can only rotate and cannot slide up and down. Rotate the limiting block 68 ninety degrees and slowly release it. When the handle 69 is pulled, the limiting block 68 will slowly descend under the tension of the tension spring 66 until it engages with the limiting slot 62 on the top side of the limiting sleeve 61. At this point, the pontoon 5 is locked on one side. The other side is operated in the same way, thus completely completing the installation between the motor 2 and the pontoon 5. At this time, the motor slot 53 will provide support for the motor 2, the motor limiting plate 56 will limit the upper and lower movement of the motor 2, the limiting protrusion 55 will strengthen the limiting of the motor 2, and the annular plate 21 and the locking hole 57 will completely fix the motor 2 in place. When the motor 2 is in motion... When the motor 2 is rotating, the heat generated will be transferred to the temperature conducting plate 58 through the limiting protrusion 55, the motor limiting plate 56 and the annular plate 21. The temperature conducting plate 58 will then conduct the heat into the water to enhance the heat dissipation of the motor 2. When disassembly is required for maintenance or repair, simply pull the handle 69 again to move the limiting block 68 upward, then rotate the limiting block 68 ninety degrees to release the limiting block 68 and unlock the portable installation component 6. Then remove the long lock block 63 and the limiting sleeve 61, and then pull the two snap-fit ​​floats 51 to the sides to complete the disassembly of the device.
