Obviously, the following description of the structure of the drawings is only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained without creative labor. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application.

[0023] Embodiment:

[0024] At present, the overflow port of the magnetic separator tank is arranged at the tank bottom. Whenever the overflow flow needs to be adjusted, the pump and the machine need to be stopped, and then the overflow adjustment can be performed. In this way, not only time and effort are wasted, but also the mineral washing and processing is temporarily suspended during the pump and machine stop, which greatly affects the efficiency of mineral washing and processing. Therefore, we design a device which is convenient to operate and can adjust the overflow flow of the magnetic separator without stopping the pump and the machine. The specific scheme is as follows:

[0025] As Figure 1As shown, the embodiment provides a magnetic separator overflow adjusting device, including support assembly 1, the front end of support assembly 1 is vertically installed with rotatable rotating shaft mechanism 2, the bottom of support assembly 1 is installed with adjusting disc 4, and the top of support assembly 1 is installed with operation unit 3, wherein, support assembly 1 is installed on the groove of the magnetic separator tank, and plays a supporting role for the whole overflow adjusting mechanism, and the cooperation of operation unit 3 and rotating shaft mechanism 2 can make the user rotate rotating shaft mechanism 2 through operation unit 3, so that rotating shaft mechanism 2 drives adjusting disc 4 at the bottom to rotate, thereby adjusting the water flow of the overflow port at the bottom of the magnetic separator tank according to the rotation angle of adjusting disc 4, thereby playing an overflow adjusting effect, the whole device has simple structure and low cost, the whole overflow adjusting operation is above the tank, and the operation process does not need to stop the pump and machine, which can effectively shorten the overflow adjusting time of the magnetic separator under the premise of not affecting the mineral washing and processing efficiency, and is very practical.

[0026] As Figures 2-3 shown, in order to further improve the practicability of the device during use, the support assembly 1 thereof includes a mounting right-angle plate 101, the tail end of the mounting right-angle plate 101 is provided with a mounting hole 102, the inner side of the mounting hole 102 is provided with a mounting bolt 103 for fixing and mounting the mounting right-angle plate 101 and the groove of the magnetic separator tank together, the inner side of the corner of the mounting right-angle plate 101 is welded with a triangular reinforcing plate to improve the compression and deformation resistance of the whole mounting right-angle plate 101, and meanwhile, the middle part of the front end of the mounting right-angle plate 101 is provided with a slot 104, the inner side of the slot 104 is slidably inserted with a telescopic plate 106, and the front end of the telescopic plate 106 is vertically fixed with a sleeve 109 penetrating through both ends of the sleeve 109, wherein, the middle part of the slot 104 is provided with upper and lower limit slot holes 105 penetrating through the slot 104 along the extension direction of the slot 104, and the middle part of the tail end of the telescopic plate 106 is provided with a anti-dropping pin 107 matched with the limit slot hole 105; the tail end plate body of the telescopic plate 106 is screwed with a locking bolt 108, and the cooperation of the telescopic plate 106, the slot 104 and the locking bolt 108 can make the horizontal position of the rotating shaft mechanism 2 of the device in the magnetic separator tank adjustable, which facilitates the installation personnel to adjust the position of the overflow adjusting mechanism in the magnetic separator tank according to the actual situation, and it should be noted that the screw hole needs to be drilled in the groove of the magnetic separator tank and corresponds to the overflow outlet at the bottom of the tank in the transverse position during the installation of the support assembly 1.

[0027] As Figures 2-4As shown, in order to improve the adaptability of the entire device when the magnetic separator tank is installed at different depths, the rotating shaft mechanism 2 adopts a telescopic structure design as a whole, specifically: the rotating shaft mechanism 2 includes a sleeve 201 inserted and penetrating the sleeve 109, and the sleeve 201 is rotatably installed between the sleeve 109, and at the same time, the sleeve 201 is externally located at both ends of the sleeve 109. A positioning ring is installed at each position to prevent the sleeve 201 from sliding up and down inside the sleeve 109, so that the sleeve 201 can only make horizontal circular motion inside the sleeve 109 and cannot move up and down inside the sleeve 109. At the same time, the bottom of the sleeve 201 is inserted with a plug rod 202, and the bottom end of the plug rod 202 is integrally formed with a plug 203 connected with the adjusting disc 4, wherein the pipe wall of the sleeve 201 is provided with a positioning slot hole 208, the top end of the plug rod 202 is provided with a slot 204, and the slot 204 is inserted with a positioning pin 205; and the top end of the plug rod 202 is located outside the slot 204 and is screwed with a positioning nut 206; the upper half of the sleeve 201 is sealed by a sealing plug 209, and the sealing plug 209 and the top end of the plug rod 202 are provided with a spring 207, and the sealing plug 209 and the upper half of the sleeve 201 are threadedly assembled.

[0028] In the above design, the cooperation between the plug rod 202 and the sleeve 201 through the positioning pin 205 and the positioning slot hole 208 makes the plug rod 202 only move up and down in the sleeve 201 and cannot rotate horizontally, so that the operator can rotate the sleeve 201 to drive the plug rod 202 to rotate, and the plug rod 202 and the sleeve 201 can still maintain the telescopic property during this process. With the cooperation of the spring 207 and the sealing plug 209, the plug rod 202 can be continuously pushed downward, the friction between the bottom of the plug rod 202 and the bottom of the magnetic separator tank is enhanced, and the self-adapting telescopic rotating shaft mechanism 2 makes the device can adapt to different depths of the tank. It needs to be further explained that the inside of the upper half of the sleeve 201 is provided with a thread to facilitate the installation personnel to adjust the position of the sealing plug 209 inside the sleeve 201 from the top end of the sleeve 201, so as to adjust the pushing force of the spring 207 on the plug rod 202.

[0029] In order to facilitate the operator to adjust the overflow flow above the magnetic separator tank, the operating unit 3 includes an operating handle 301 sleeved on the top end of the sleeve 201, and a key groove is formed between the operating handle 301 and the sleeve 201. The key pin 302 is inserted into the key groove to position the operating handle 301, avoiding the rotation of the operating handle 301 outside the sleeve 201.

[0030] In order to be able to cooperate with the rotating shaft mechanism 2 to realize the plugging and adjusting of the overflow drainage of the magnetic separator water tank bottom, realize the flow adjustment, the adjusting disc 4 comprises a plugging disc body 401, a vertical and matched sleeve head 402 is welded on one side of the top of the plugging disc body 401 and cooperates with the plug 203 at the bottom of the inserting rod 202, the sleeve head 402 is sleeved outside the plug 203, the sleeve head 402 and the plug 203 are assembled together through the fixing bolt 403 which transversely penetrates the sleeve head 402 and the plug 203, at the same time, the outer edge of the bottom of the plugging disc body 401 is designed as a 45-degree inclined surface, so that a structure similar to a knife edge is formed on the outer edge of the plugging disc body 401, which can clean the particles on the moving path during the rotation of the plugging disc body 401, and ensure that the bottom of the plugging disc body 401 can effectively contact the tank bottom of the magnetic separator water tank.

[0031] In order to facilitate the operator to more intuitively know the rotation angle of the bottom adjusting disc 4, an angle deflection reference line can be arranged on the outer edge of the sleeve 109 and the outside of the top of the sleeve pipe 201, and it should be further pointed out that: since the square plug 203 and the matched sleeve head 402 are used between the inserting rod 202 and the adjusting disc 4, and are fixedly installed through the fixing bolt 403, and the inserting rod 202 and the sleeve pipe 201 can only move, therefore, the rotation angle of the sleeve pipe 201 can feedback the rotation angle of the adjusting disc 4, and the operator can completely know the deflection angle of the rotating disc by observing the rotation angle of the sleeve pipe 201.

[0032] Finally, it should be pointed out that: the above only describes the preferred embodiments of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
