Technical Field

[0001] The invention relates to the technical field of ore dressing equipment, in particular to a lepidolite vacuum belt filter weighing system. Background Art

[0002] Lithium is an important mineral resource and plays an increasingly important role in the development of human civilization. Although lithium is called a "rare metal", its abundance in the earth's crust is as high as 0.0065%, which is much larger than the reserves of common metals such as copper, lead, and zinc. There are more than 150 known lithium-containing minerals, including spodumene, lepidolite, and petalite, and the main raw material for extracting lithium from ore is spodumene. The lithium content in seawater is not small, with a total reserve of up to 100 million tons, but the concentration is too low to be extracted. Today, with the "explosive" growth of the new energy vehicle industry, related products with lithium as the core are gradually developing into the mainstream raw materials for new energy batteries. According to industry insiders, the demand for lithium in the next 10 years will continue to be in short supply.

[0003] The vacuum belt filter uses a circulating filter cloth or filter screen as the medium, arranges the slurry horizontally on the filter medium, and uses the negative pressure and gravity provided by the vacuum equipment to quickly and continuously separate the solid and liquid. The vacuum belt filter has the advantages of simple structure, high dehydration efficiency, large processing capacity, low energy consumption, low noise, high degree of automation, continuous operation, and easy maintenance, and is widely used in the mineral processing industry. The vacuum belt filter usually uses a belt conveyor installed with an electronic belt scale for transportation and weighing, which increases the investment cost and the weighing accuracy is insufficient.

[0004] The existing electronic weighing and measuring scales can only meet the needs of equipment with a smaller width under dynamic conditions, and have large requirements for installation space. In addition, the electronic belt scale installed on the existing vacuum belt filter through modification will cause changes in the results of the original filter, bringing about labor costs for the modification and expenses caused by structural changes. Therefore, there are still great problems with applicability. Summary of the invention

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] Reference Figures 1 to 5As shown, the lithium mica vacuum belt filter weighing system of the present invention is provided with a circulating filter cloth 2 on the frame 1 of the filter, and the filter cloth 2 is supported by a plurality of rollers 3 on the frame 1. The filter cloth 2 has a horizontal section with a horizontal surface, and the lower surface of the filter cloth 2 in the horizontal section forms a driving match with the adhesive tape, so that the entire filter cloth 2 is circulated. The adhesive tape is wound on two driving wheels and driven by the driving wheels to transmit, and the adhesive tape drives the filter cloth 2 above to circulate. The slurry is fed from one end of the horizontal section surface of the filter cloth 2 by an external discharge device, and then carried forward by the filter cloth 2. During the slurry transmission process, the slurry on the filter cloth 2 is dehydrated and dried by a vacuum device, and finally a lithium mica mineral product that can be shipped is produced.

[0032] The present invention provides a floating balance frame composed of a roller support 4, a roller mounting seat 5, a weighing mechanism 6 and at least two rollers 3 on the discharge end of the frame 1, and uses the floating balance frame to weigh the slurry above the filter cloth 2. Two weighing mechanisms 6 are provided on the frame 1 on both sides of the filter cloth 2, the bottom of the weighing mechanism 6 is installed on the frame 1, the top of the weighing mechanism 6 is correspondingly connected to the roller support 4, and the two ends of each roller support 4 are respectively connected to the two weighing mechanisms 6. The roller support 4 is provided on the frame 1 on both sides of the filter cloth 2 through the weighing mechanism 6, the roller 3 is provided at the bottom of the filter cloth 2, and the two ends of the roller 3 are correspondingly installed on the roller support 4 on both sides of the filter cloth 2.

[0033] A roller mounting seat 5 is provided on the lower surface of the roller bracket 4 in the length direction. The number of the roller mounting seats 5 corresponds to the number of rollers 3 in the floating balancing frame. Both ends of each roller 3 are rotatably connected to the roller mounting seats 5 on both sides. Preferably, the ends of the rollers 3 are rotatably connected to the roller mounting seats 5 via a bearing structure.

[0034] The weighing mechanism 6 includes a module top plate 7, a support column 8, a weighing sensor 9, a limit column 10, a module bottom plate 11 and a balance support frame 12. The support column 8, the weighing sensor 9, the limit column 10 and the balance support frame 12 are arranged between the module top plate 7 and the module bottom plate 11. The module bottom plate 11 is installed on the frame 1, the weighing sensor 9 is installed above the module bottom plate 11, and the top of the weighing sensor 9 is provided with a support column 8, which is movably connected to the module top plate 7 upward. Preferably, the support column 8 adopts a cylindrical structure, and the top of the support column 8 is movably connected to the module top plate 7 through a universal joint. The balance support frame 12 adopts a U-shaped frame opened to both sides, and the top of the balance support frame 12 is fixedly connected to the bottom of the module top plate 7. The weighing sensor 9 extends into the interior of the balance support frame 12 so that the support column 8 is movably connected to the upper module top plate 7. A through hole is opened at the bottom of the balance support frame 12, and a limiting column 10 is arranged in the bottom through hole of the balance support frame 12. The limiting column 10 is vertically arranged on the module bottom plate 11. The top of the limiting column 10 has a nut, and the bottom is fixedly arranged on the module bottom plate 11. The balance support frame 12 is sleeved on the limiting column 10 and is limited by the limiting column 10.

[0035] The roller bracket 4 is a U-shaped slat, a threaded hole is provided on the roller bracket 4, a through hole is provided on the module top plate 7, the threaded hole of the roller bracket 4 and the through hole of the module top plate 7 correspond to each other, and the roller bracket 4 and the module top plate 7 are fixedly connected by fasteners. Preferably, a through hole is arranged at each of the four corners of the module top plate 7, and the four corners are fixedly connected to the roller bracket 4.

[0036] The present invention is also provided with a speed sensor corresponding to the driving wheel, and the speed sensor can measure the rotation speed of the driving wheel. The present invention also includes an integrator, which is connected to the weighing sensor 9 and the speed sensor of the weighing mechanism 6 by electrical signals, and the weight value measured by the weighing sensor 9 and the rotation speed of the driving wheel measured by the speed sensor are transmitted to the integrator, and the integrator performs calculations and measurements to obtain the weight of the material transmitted on the filter.

[0037] When the present invention is implemented, a floating balance frame is added to the frame 1 of the vacuum belt filter. The floating balance frame is installed by using the roller 3 structure of the filter equipment itself. A weighing mechanism 6 is installed on both sides of the filter cloth 2 at the discharge end of the original floating balance frame equipment. The weighing mechanism 6 is equipped with a weighing sensor 9. The weighing mechanism 6 is connected to the weighing mechanism 6 through the roller bracket 4 and the roller mounting seat 5 to form an integral weighing floating bridge structure. Since the two rollers 3 are only installed on the roller bracket 4 through the roller mounting seat 5, the roller bracket 4 is connected to the weighing mechanism 6 and the roller bracket 4 is supported by the weighing mechanism 6. The weight borne on the rollers 3 is finally carried by the weighing mechanism 6 and can be measured. The entire structure composed of the roller bracket 4, the roller mounting seat 5, and the weighing mechanism 6 floats freely like a floating bridge, and the influence of various interferences or structural internal stresses is minimized. The roller bracket 4 fully and accurately transmits the weight of the material on the filter cloth 2 to the weighing sensor 9 to complete high-precision measurement. Since the four weighing sensors 9 are arranged below the roller bracket 4 and constitute four supporting angles of the weighing system, the filter has the characteristics of strong anti-eccentric load capability and wide adaptability to the vacuum belt filter.

[0038] The present invention utilizes the working principle of an electronic belt scale and realizes the integrated measurement function through the synergistic effect of a weighing sensor 9 and a speed sensor. When the material passes through the weighing bridge module, the roller 3 with a metering function detects the weight of the material on the filter cloth 2 and transmits it to the weighing sensor 9 to complete high-precision metering. At the same time, the speed sensor directly measures the speed of the driving wheel roller mounting seat 5 of the frame 1, which can effectively ensure the accuracy of the measurement.

[0039] Embodiment 2:

[0040] Since the filter cloth of the vacuum belt filter has a certain degree of ductility, the filter cloth will have a certain length difference due to the ductility after being used for a long time. The length difference of the filter cloth cannot be monitored during the calculation process of the integrator, which will affect the change of measurement accuracy. It is necessary to recalibrate after running for a period of time to restore the weighing accuracy. For this reason, the present invention provides an improved embodiment 2 as follows.

[0041] like Figure 6 As shown, in addition to having all the components of embodiment 1, the present embodiment differs from the embodiment in that the roller bracket 4 and the weighing mechanism 6 of the present invention are connected by fastening bolts, and an adjusting knob 13 is sleeved on the screw rod of the fastening bolt between the roller bracket 4 and the weighing mechanism 6. The adjusting knob 13 adopts a circular ring structure, and a through threaded hole is opened in the center of the adjusting knob 13. The threaded hole of the adjusting knob 13 cooperates with the screw rod of the fastening bolt between the roller bracket 4 and the weighing mechanism 6. The outer periphery of the adjusting knob 13 is provided with an array of anti-slip grooves to facilitate the rotation adjustment operation of the adjusting knob 13.

[0042] By providing an adjusting knob 13 on the screw of the fastening bolt between the roller bracket 4 and the weighing mechanism 6, the distance between the roller bracket 4 and the weighing mechanism 6 can be adjusted, thereby achieving adjustment of the height and level of each roller bracket 4. When the filter cloth 2 has a certain length difference due to its ductility, the error caused by the length difference of the filter cloth 2 due to its ductility can be reduced by adjusting the adjusting knob 13, so that the present invention is in a good use state, the occurrence of errors is reduced, and the accuracy of weighing measurement is improved.

[0043] Embodiment 3:

[0044] For a weighing system, its accuracy is crucial to serve as an accurate measuring tool. In order to ensure the accuracy of the weighing results, the weighing system must be placed horizontally as much as possible. This is because horizontal placement can effectively avoid errors caused by changes in gravity components and ensure the accuracy of the weighing results. If it cannot be placed horizontally, it will not only cause deviations in the weighing results, but may also affect the service life of the instrument and cause measurement errors. The present invention is a device with a large weighing coverage area. In order to improve the accuracy of the present invention, the present invention provides an improved embodiment 3 as follows.

[0045] like Figures 7 to 10 As shown, in addition to all the components of Example 1, this embodiment further has the following technical features: The roller mounting seat 5 provided on the lower surface in the length direction of the roller support 4 is fastened and connected by a round head bolt 14, which is composed of a rod with a thread and a spherical head. The rod of the round head bolt 14 passes upward through the through hole on the roller mounting seat 5 and is connected with the threaded hole on the roller support 4, and the spherical head of the round head bolt 14 abuts against the through hole of the roller mounting seat 5. The spherical head of the round head bolt 14 contacts the through hole of the roller mounting seat 5, so that the adverse effect on the horizontal state caused by the fit between the planes between the fastener and the roller mounting seat 5 can be avoided.

[0046] A bubble level 15 is provided on the outer side surface in the length direction of the roller bracket 4, and the horizontal state of the roller bracket 4 can be displayed by the bubble level 15. The bubble level 15 includes a long sealed cavity and a filling liquid in the cavity, and the filling liquid has a bubble. Whether the roller bracket 4 is in a horizontal state can be judged by whether the bubble is located at the center in the length direction of the bubble level 15, so as to make adjustments and corrections to ensure that the roller bracket 4 is in a horizontal state, thereby improving the accuracy of the weighing measurement of the present invention.

[0047] In order to ensure that the roller supports 4 on both sides of the filter cloth 2 in the present invention are in a horizontal plane state, the present invention also includes a light transmitter 16 and a light receiver 17, which are arranged above the roller supports 4, and the bottoms of the light transmitter 16 and the light receiver 17 extend into the roller supports 4, and the light transmitter 16 and the light receiver 17 can be removed when not in use. The light transmitter 16 and the light receiver 17 are arranged correspondingly, and the light receiver 17 receives the light emitted by the corresponding light transmitter 16 and displays the information whether it is received. The light transmitter 16 and the light receiver 17 are arranged on the roller supports 4 on one side, and the corresponding light receiver 17 and the light transmitter 16 are arranged on the roller supports 4 on the other side. Through the two sets of mutually coordinated light transmitters 16 and light receivers 17, it can be seen whether the roller supports 4 on both sides of the filter cloth 2 are in a horizontal plane state, so as to make adjustments and corrections, thereby improving the accuracy of the weighing measurement of the present invention.

[0048] In order to ensure that the weighing mechanism 6 in the present invention is installed in a horizontal state on the frame 1, the present invention also includes a circular level 18 arranged on the upper surface of the module base plate 11 of the weighing mechanism 6. The circular level 18 includes a circular sealed cavity and a filling liquid located in the cavity. The filling liquid has a bubble. Whether the weighing mechanism 6 is in a horizontal state is determined by whether the bubble is located at the circular center of the circular level 18, so that adjustments and corrections can be made to improve the accuracy of the weighing measurement of the present invention.

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
