Description

Technical Field

[0001] The utility model relates to the technical field of flotation machines, in particular to an assembling and mounting bracket for impeller blades of a flotation machine. Background Art

[0002] Flotation machines, also known as floatation concentrators, are essential equipment for the flotation process. Their working principle relies on an electric motor driving the impeller, creating a centrifugal force that generates negative pressure. This action draws in sufficient air to mix with the slurry, while also stirring the slurry and reagents. This process also refines the foam, causing mineral particles to adhere to the bubbles and float to the slurry surface, forming a mineralized foam layer and ultimately achieving mineral separation.

[0003] The impeller of the flotation machine is generally installed at the bottom of the flotation box through a bracket. During use, mud will inevitably adhere to the upper surface of the impeller. If it is not cleaned in time, the mud attached to the upper surface of the impeller will dry. The dried mud has strong adhesion, and workers need to enter the flotation box to clean it, which is inconvenient to use. Summary of the Invention

[0004] The purpose of the utility model is to provide a flotation machine impeller blade assembly and installation bracket to solve the problem in the prior art that workers need to enter the flotation box to clean the impeller.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solution: a flotation machine impeller blade assembly mounting bracket, comprising an assembly bracket, a bearing fixedly mounted on the assembly bracket, a mounting shaft fixedly mounted in the bearing, an impeller body fixedly mounted on the lower end of the mounting shaft, a blade body fixedly mounted on the impeller body, a cleaning mechanism fixedly mounted on the assembly bracket, the cleaning mechanism comprising a telescopic guide rod movably mounted on the assembly bracket, a spring seat fixedly mounted on the telescopic guide rod, a return spring sleeved on the telescopic guide rod, an armature block fixedly mounted on the upper end of the telescopic guide rod, an electromagnet provided above the armature block, a cleaning scraper fixedly mounted on the lower end of the telescopic guide rod, a control mechanism connected to the assembly bracket, the control mechanism comprising a toggle switch fixedly mounted on the assembly bracket, a connecting shaft movably mounted on the toggle lever of the toggle switch, a toggle piece fixedly mounted on the connecting shaft, a torsion spring sleeved on the connecting shaft, a toggle block fixedly mounted on the mounting shaft, the torsion spring providing torsion to the connecting shaft so that the toggle block is aligned with the toggle lever on the toggle switch.

[0006] Preferably, a connecting bracket is fixedly mounted on the cleaning scraper, a connecting sleeve is provided in the middle of the connecting bracket, and the telescopic guide rod can drive the cleaning scraper to move up and down.

[0007] Preferably, a movable slot is provided on the assembly bracket, and the telescopic guide rod is movably mounted on the assembly bracket through the movable slot.

[0008] Preferably, one end of the return spring is connected to the spring seat, and the other end of the return spring is connected to the bottom of the movable groove. The cleaning scraper is movably installed under the assembly bracket through a telescopic guide rod, and the connecting bracket is movably installed on the outside of the mounting shaft through a connecting sleeve. The return spring provides elastic force for the spring seat, so that the spring seat has a tendency to move downward.

[0009] Preferably, a positioning sleeve is provided on the toggle block, and the toggle block is fixed on the mounting shaft through the positioning sleeve, and the mounting shaft can rotate in the positioning sleeve.

[0010] Preferably, the toggle switch is connected to the power line of the electromagnet, and the toggle switch and the toggle block are on the same horizontal plane. After the power of the electromagnet is turned on, it will adsorb the armature block.

[0011] Preferably, the toggle block is movably mounted on the toggle lever of the toggle switch via a connecting shaft, one end of the torsion spring is fixed on the connecting shaft, and the other end of the torsion spring is fixed on the toggle lever of the toggle switch, and the toggle switch can control whether the electromagnet is started.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this application, after the power supply of the electromagnet is disconnected, the armature block will be released. After the armature block is released, the return spring will push the spring seat to move downward, thereby causing the telescopic guide rod to move downward. The downward moving telescopic guide rod will drive the cleaning scraper to contact the upper surface of the impeller body, thereby cleaning the solidified mud on the upper surface of the impeller body when the impeller body rotates counterclockwise, which is convenient for users to use.

[0014] 2. In this application, the motor can drive the mounting shaft to rotate in different directions. When the mounting shaft rotates clockwise, it will drive the toggle block on the positioning sleeve to rotate clockwise, and move the lever on the toggle switch to one side, thereby turning on the power supply of the electromagnet. After the mounting shaft rotates counterclockwise, it will drive the toggle block on the positioning sleeve to rotate counterclockwise, and move the lever on the toggle switch to the other side, thereby disconnecting the power supply of the electromagnet, making it easier for users to control the cleaning scraper operation.

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution for an assembly and mounting bracket for an impeller blade of a flotation machine, comprising an assembly bracket 3, a bearing 4 fixedly mounted on the assembly bracket 3, a mounting shaft 5 fixedly mounted inside the bearing 4, an impeller body 1 fixedly mounted on the lower end of the mounting shaft 5, a blade body 2 fixedly mounted on the impeller body 1, a cleaning mechanism 6 fixedly mounted on the assembly bracket 3, and a control mechanism 7 connected to the assembly bracket 3. The cleaning mechanism 6 cooperates with the control mechanism 7 to clean the solidified mud on the upper surface of the impeller body 1 when the impeller body 1 rotates counterclockwise.

[0023] like Figure 2 and Figure 3 As shown, the cleaning mechanism 6 includes a telescopic guide rod 602 movably mounted on the assembly bracket 3, a spring seat 605 is fixedly mounted on the telescopic guide rod 602, a return spring 606 is sleeved on the telescopic guide rod 602, an armature block 607 is fixedly mounted on the upper end of the telescopic guide rod 602, an electromagnet 608 is provided above the armature block 607, a cleaning scraper 601 is fixedly mounted on the lower end of the telescopic guide rod 602, a connecting bracket 604 is fixedly mounted on the cleaning scraper 601, and a connecting sleeve 603 is provided in the middle position of the connecting bracket 604.

[0024] Specifically, after the power supply of the electromagnet 608 is disconnected, it will release the armature block 607. After the armature block 607 is released, the return spring 606 will push the spring seat 605 to move downward, thereby causing the telescopic guide rod 602 to move downward. The downward moving telescopic guide rod 602 will drive the cleaning scraper 601 to contact the upper surface of the impeller body 1, thereby cleaning the solidified mud on the upper surface of the impeller body 1 when the impeller body 1 rotates counterclockwise.

[0025] like Figure 2 Figure 4 and Figure 5 As shown, the control mechanism 7 includes a toggle switch 701 fixedly mounted on the assembly bracket 3, a connecting shaft 702 movably mounted on the toggle lever of the toggle switch 701, a toggle piece 703 fixedly mounted on the connecting shaft 702, a toggle spring 706 sleeved on the connecting shaft 702, a toggle block 704 fixedly mounted on the mounting shaft 5, a positioning sleeve 705 provided on the toggle block 704, the toggle block 704 is fixed to the mounting shaft 5 through the positioning sleeve 705, the toggle switch 701 is connected to the power line of the electromagnet 608, one end of the torsion spring 706 is fixed on the connecting shaft 702, and the other end of the torsion spring 706 is fixed on the toggle lever of the toggle switch 701.

[0026] Specifically, the motor can drive the mounting shaft 5 to rotate in different directions. When the mounting shaft 5 rotates clockwise, it will drive the toggle block 704 on the positioning sleeve 705 to rotate clockwise, and move the toggle lever on the toggle switch 701 to one side, thereby turning on the power of the electromagnet 608. After the mounting shaft 5 rotates counterclockwise, it will drive the toggle block 704 on the positioning sleeve 705 to rotate counterclockwise, and move the toggle lever on the toggle switch 701 to the other side, thereby disconnecting the power of the electromagnet 608, making it easier for the user to control the operation of the cleaning scraper 601.

[0027] Working principle: When in use, the motor can be used to drive the mounting shaft 5 to rotate clockwise. After the mounting shaft 5 rotates clockwise, it will drive the blade body 2 on the impeller body 1 to rotate, thereby stirring the mud in the flotation machine, and when the mounting shaft 5 rotates clockwise, it will drive the toggle block 704 on the positioning sleeve 705 to rotate clockwise. When the toggle block 704 rotates clockwise, the toggle lever on the toggle switch 701 will be toggled to one side, thereby turning on the power supply of the electromagnet 608, so that the electromagnet 608 attracts the armature block 607. At the same time, the motor can be used to drive the mounting shaft 5 to rotate counterclockwise. After the mounting shaft 5 rotates counterclockwise, it will drive the toggle block 704 on the positioning sleeve 705 to rotate counterclockwise. When the toggle block 704 rotates counterclockwise, the toggle lever on the toggle switch 701 will be toggled to the other side, thereby When the power supply of the electromagnet 608 is disconnected, the armature block 607 will be released. Since one end of the return spring 606 is connected to the spring seat 605, and the other end of the return spring 606 is connected to the bottom of the movable groove, the cleaning scraper 601 is movably installed under the assembly bracket 3 through the telescopic guide rod 602. Therefore, after the armature block 607 is released, the return spring 606 will push the spring seat 605 to move downward. After the spring seat 605 moves downward, the telescopic guide rod 602 will move downward. The downward moving telescopic guide rod 602 will drive the cleaning scraper 601 to contact the upper surface of the impeller body 1. When the cleaning scraper 601 contacts the upper surface of the impeller body 1, the mounting shaft 5 will drive the impeller body 1 to rotate counterclockwise, so as to clean the solidified mud on the upper surface of the impeller body 1.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
