Description

Technical Field

[0001] The present application relates to the field of flotation machines, and in particular to a high-efficiency energy-saving single-tank flotation machine. Background Art

[0002] The single-tank flotation machine is an important equipment for flotation process with only one tank. It is suitable for the separation of non-ferrous metals and non-metallic materials. The single-tank flotation machine is driven by an electric motor to rotate the impeller, which generates a centrifugal effect to form a negative pressure. On the one hand, it inhales sufficient air to mix with the slurry, and on the other hand, it stirs the slurry and mixes the drugs. At the same time, it refines the foam, so that the minerals adhere to the foam, float to the surface of the slurry and form mineralized foam. The useful foam is scraped out by the scraper.

[0003] The scraped foam is collected in a foam collection box. A single-slot flotation machine is usually provided with a pallet for supporting the foam collection box. The pallet is connected to the base of the single-slot flotation machine by a support rod. The support rod is rotatably connected to the base. The pallet and the foam collection box can be moved to the foam collection position or away from the collection position by rotating the support rod to facilitate the removal and placement of the foam collection box.

[0004] With regard to the above-mentioned related technologies, the slurry in the flotation machine is continuously consumed, and the staff needs to constantly observe the slurry remaining in the flotation machine and replenish the slurry in time when the slurry is insufficient to maintain the continuation of the flotation work, which requires continuous use of a certain amount of manpower and has a high cost of use. Utility Model Content

[0008] The sensing module includes a liquid level meter, which is used to detect the liquid level in the flotation box and output a sensing signal;

[0009] A comparison module, the comparison module is electrically connected to the sensing module, and the comparison module is used to receive the sensing signal of the sensing module. When the comparison module receives the sensing signal, the voltage value corresponding to the sensing signal is compared with a preset voltage value. If the voltage value of the sensing signal is less than the preset voltage value, the comparison module outputs a start signal. The preset voltage value corresponds to the voltage value corresponding to the minimum liquid level height that enables the flotation work to proceed normally.

[0010] The control module is electrically connected to the comparison module. The control module is used to receive a start signal from the comparison module. When the control module receives the start signal, it outputs a control signal, and the control signal controls the solenoid valve to open.

[0011] By adopting the above technical solution, the liquid level meter of the sensing module detects the liquid level height of the slurry in the flotation box and outputs a sensing signal, the comparison module receives the sensing signal, and the comparison module compares the voltage value of the received sensing signal with the preset voltage value. The preset voltage value corresponds to the voltage value corresponding to the minimum liquid level height that can enable the flotation work to proceed normally. If the voltage value corresponding to the sensing signal is less than the preset voltage value, a start signal is output, and the control module receives the start signal and outputs a control signal. The control signal controls the solenoid valve to open, so that raw materials can be automatically added to the flotation box when the slurry is insufficient, thereby realizing automatic addition of slurry.

[0012] Optionally, a conversion block is rotatably connected to the base and the rotation axis of the conversion block is vertically arranged, at least two support rods are connected to the side of the conversion block, and the support rods are provided with a support plate for supporting the foam collection box, and the path of the support plate moving with the support rods passes through the foam discharge position of the flotation box.

[0013] By adopting the above technical solution, when filling foam into the foam collection box, the empty foam collection box is placed on other supporting plates in advance. When one foam collection box is full, the conversion block can be directly rotated, and the support rod and the supporting plate rotate accordingly, so that the full foam collection box is moved out of the foam collection position, and the empty foam collection box is aligned with the foam discharge position to continue collecting foam. The steps of replacing the foam collection box are simple and quick, which helps to reduce the time taken to replace the foam collection box and improve the replacement efficiency of the foam collection box.

[0014] Optionally, a conversion motor for driving the conversion block to rotate is provided on the base.

[0015] By adopting the above technical solution, the conversion motor drives the conversion block to rotate to achieve the switching of the foam collection box. The machine replaces manual labor, which helps to save labor.

[0017] By adopting the above technical solution, when collecting foam, the foam collection box needs to be moved to the position facing the foam discharge position, otherwise it will cause the foam to spill and be wasted. A positioning block is set. When the support plate contacts the positioning block, under the action of the guide slope, the positioning block is squeezed and then slides into the positioning groove, and the support plate can continue to move. When the support plate moves to a position aligned with the foam discharge position, the positioning block is aligned with the card slot, and the positioning block enters the card slot under the drive of the first elastic member to fix the position of the support plate. It is convenient to quickly locate the position of the support plate and the foam collection box, which helps to improve efficiency.

[0018] Optionally, the slot is arranged through a pallet, and a movable plate for supporting the foam collection box is provided on the upper surface of the pallet, and a plurality of second elastic members for supporting are connected between the movable plate and the pallet. A push rod for ejecting the positioning block from the slot is provided on the side of the movable plate close to the pallet. When the empty foam collection box is placed on the movable plate, the push rod is located outside the slot, and when the foam collection box is full, the push rod is embedded in the slot.

[0019] By adopting the above technical solution, when filling the foam collection box, the overall mass of the foam collection box gradually increases, the movable plate is pressed down, and the push rod moves with the movable plate. After the foam collection box is full, the push rod is embedded in the embedded card slot and the fixed block is pushed out of the card slot, and the support plate is released from the limit and can continue to move. It is convenient to release the limit of the support plate in time after the foam collection box is full and switch to an empty foam collection box to continue filling.

[0020] Optionally, the upper surface of the movable plate is provided with an anti-skid pad for increasing the friction between the movable plate and the foam collection box.

[0022] Optionally, the discharging mechanism includes a discharging motor and a scraper. The discharging motor is arranged on the frame and the length direction of the output shaft of the discharging motor is arranged perpendicular to the foam discharging direction. The output shaft of the discharging motor is vertically connected to a transmission rod, and the transmission rod is connected to a cross bar arranged parallel to the output shaft of the discharging motor, and the scraper is rotatably connected to the cross bar.

[0023] By adopting the above technical solution, the discharging motor drives the transmission rod to rotate, and the transmission rod drives the cross bar to rotate in the vertical direction around the output shaft of the discharging motor, thereby driving the scraper to change its height periodically and reciprocate in the horizontal direction at the same time to scrape out the foam and realize automatic discharging.

[0024] Optionally, the flotation box can be detachably connected to the frame.

After filling one foam collection box, directly turn the conversion block to move the full foam collection box out of the foam collection position, and at the same time align the empty foam collection box with the foam discharge position to continue collecting foam. The process of replacing the foam collection box is simple and quick, which helps to reduce the time taken to replace the foam collection box and improve the replacement efficiency of the foam collection box;

[0028] 2. When collecting foam, the foam collection box needs to be moved to a position directly opposite the foam discharge position. It takes a certain amount of time to align the position of the foam collection box. A positioning block is set. When the pallet moves to a position aligned with the foam discharge position, the positioning block is aligned with the slot. The positioning block enters the slot under the drive of the first elastic member to lock the position of the pallet, which helps to quickly locate the pallet and the foam collection box.

[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0035] The embodiment of the present application discloses a high-efficiency energy-saving single-tank flotation machine.

A liquid level gauge 211 for detecting the liquid level in the flotation box 21 is provided on the flotation box 21. When the slurry is insufficient, raw materials can be automatically added to the flotation box 21 to realize automatic addition of slurry.

[0037] Reference Figure 1 and Figure 3 , a detection and control circuit is provided on the rack 2, and the detection and control circuit includes a sensing module 4, a comparison module 5 and a control module 6:

[0038] The sensing module 4 includes a liquid level meter 211, which is installed on the flotation box 21, detects the liquid level of the slurry in the flotation box 21, and outputs a sensing signal;

[0047] A solenoid valve 241, one end of the solenoid valve 241 is electrically connected to an end of the normally open switch KA1-1 of the relay away from the resistor R2;

[0048] The resistor R3 has one end electrically connected to one end of the electromagnetic valve 241 away from the normally open switch KA1 - 1 of the relay, and the other end of the resistor R3 is grounded.

[0049] Reference Figure 1 and Figure 3 The liquid level meter 211 of the sensing module 4 detects the liquid level of the slurry in the flotation box 21 and outputs a sensing signal. The comparison module 5 receives the sensing signal and compares the voltage value of the received sensing signal with a preset voltage value. The preset voltage value corresponds to the voltage value corresponding to the minimum liquid level that enables the flotation to work normally. If the voltage value corresponding to the sensing signal is less than the preset voltage value, a start signal is output. The control module 6 receives the start signal and outputs a control signal. The control signal controls the solenoid valve 241 to open. When the slurry is insufficient, the solenoid valve 241 can be automatically opened in time to add raw materials to the flotation box 21.

[0050] Reference Figure 2When replacing the foam collection box, it is necessary to rotate the support rod 71 to move the support plate 72 out of the collection position. After replacing the empty foam collection box, rotate the support rod 71 to move the support plate 72 and the empty foam collection box to the collection position to continue collecting foam. The steps of replacing the foam collection box are relatively cumbersome. The base 1 is rotatably connected with a conversion block 7, and at least two support rods 71 ​​are connected along the circumference of the conversion block 7. A support plate 72 is provided at one end of the support rod 71 away from the conversion block 7. The path of the support plate 72 moving with the support rod 71 passes through the foam discharge position of the flotation box 21. When filling the foam into the foam collection box, the empty foam collection box is placed on other support plates 72 in advance. When one foam collection box is filled, the conversion block 7 can be directly rotated to switch to the empty foam collection box to continue collecting foam. The steps are simple and quick, which helps to reduce the time taken to replace the foam collection box and improve the replacement efficiency of the foam collection box.

[0051] Reference Figure 4 A conversion motor 8 is installed on the base 1, and the output shaft of the conversion motor 8 is coaxially fixedly connected with the driving wheel. A driven gear is coaxially fixedly connected to the conversion block 7. The driving wheel is connected with a plurality of elastic paddles for driving the driven gear to rotate. The conversion motor 8 drives the conversion block 7 to rotate to realize the switching of the foam collection box. The machine replaces manual labor, which helps to save labor.

[0052] Reference Figure 2 and Figure 4 When collecting foam, the foam collection box needs to be moved to the position facing the foam discharge position, otherwise the risk of foam spilling and wasting will increase, and the position correction of the foam collection box takes a certain amount of time. A positioning groove 11 is provided on the upper surface of the base 1, and a positioning block 12 is vertically slidably connected in the positioning groove 11. A first elastic member 13 is connected between the bottom wall of the positioning groove 11 and the positioning block 12. The first elastic member 13 is a spring. The positioning block 12 is provided with a guide slope 121 for avoiding the passage of the support plate 72. When the support plate 72 contacts the positioning block 12, under the action of the guide slope 121, the positioning block 12 is squeezed and then slides into the positioning groove 11, and the support plate 72 can continue to move. The support plate 72 is provided with a slot 721 adapted to the positioning block 12. When the support plate 72 moves to a position aligned with the foam discharge position, the positioning block 12 is aligned with the slot 721. The positioning block 12 enters the slot 721 under the drive of the first elastic member 13, thereby locking the position of the support plate 72. This facilitates and quickly locates the positions of the support plate 72 and the foam collection box, which helps to improve efficiency.

[0053] Reference Figure 2, the slot 721 runs through the upper and lower ends of the support plate 72, and the upper surface of the support plate 72 is vertically slidably connected with a movable plate 722, which is used to contact and support the foam collection box. A plurality of second elastic members 723 are connected between the movable plate 722 and the support plate 72, and the second elastic members 723 are springs. A push rod 724 is connected to the side of the movable plate 722 close to the support plate 72. When the empty foam collection box is placed on the movable plate 722, the push rod 724 is located outside the slot 721. When the foam is filled into the foam collection box, the overall mass of the foam collection box gradually increases, the movable plate 722 slides down, and the push rod 724 moves with the movable plate 722. After the foam collection box is full, the push rod 724 is embedded in the embedded slot 721 and the fixed block is pushed out of the slot 721, and the support plate 72 is released from the limit and can continue to move. It is convenient to timely release the limit of the support plate 72 after the foam collection box is full and switch to the empty foam collection box to continue filling.

[0054] Reference Figure 2 The foam collection box needs to move horizontally with the movable plate 722. The upper surface of the movable plate 722 is provided with an anti-skid pad 725. The anti-skid pad 725 is made of soft rubber, which helps to increase the friction coefficient between the foam collection box and the foam collection box, so that the foam collection box can move more stably with the movable plate 722.

[0055] Reference Figure 1 The discharging mechanism 3 includes a discharging motor 31 and a scraper 32. The discharging motor 31 is arranged on the frame 2 and the length direction of the output shaft of the discharging motor 31 is perpendicular to the foam discharging direction. The output shaft of the discharging motor 31 is vertically connected with a transmission rod 311. The discharging motor 31 mobilizes the transmission rod 311 to rotate. The transmission rod 311 is connected with a cross bar 312 arranged parallel to the output shaft of the discharging motor 31. The transmission rod 311 drives the cross bar 312 to rotate around the output shaft of the discharging motor 31 in the vertical direction. The cross bar 312 is rotatably connected to the scraper 32. The cross bar 312 drives the height of the scraper 32 to change periodically, and at the same time reciprocates in the horizontal direction to scrape out the foam, thereby realizing automatic discharging.

[0056] Reference Figure 1 The slag accumulated in the flotation box 21 needs to be cleaned regularly. The flotation box 21 can be detachably connected to the frame 2, which is convenient for quickly removing the flotation tank and cleaning it, which helps to improve the cleaning efficiency of the flotation tank.

[0057] The implementation principle of a high-efficiency energy-saving single-tank flotation machine in the embodiment of the present application is as follows: the liquid level meter 211 of the sensing module 4 detects the liquid level height of the slurry in the flotation box 21 and outputs a sensing signal, the comparison module 5 receives the sensing signal, and the comparison module 5 compares the voltage value of the received sensing signal with a preset voltage value. The preset voltage value corresponds to the voltage value corresponding to the minimum liquid level height that can enable the flotation work to proceed normally. If the voltage value corresponding to the sensing signal is less than the preset voltage value, a start signal is output, and the control module 6 receives the start signal and outputs a control signal. The control signal controls the solenoid valve 241 to open, so that raw materials can be automatically added to the flotation box 21 when the slurry is insufficient, thereby realizing automatic addition of slurry.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
