Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing equipment, in particular to an automatic walking type flushing device for a filter. Background Art

[0002] Lithium is a key mineral resource among all types of minerals, playing an increasingly crucial role in the development of human civilization. With the explosive growth of the new energy vehicle industry, lithium-based products are gradually becoming the mainstream raw material for new energy batteries. Industry insiders predict that demand for lithium will continue to outstrip supply over the next 10 years. Lithium ore is ground in a ball mill, slurried, and then heated in a hot wash tank. The mixed slurry is then subjected to solid-liquid separation using a vacuum belt filter. The remaining solids are then further slurried with water to produce a concentrate slurry. To ensure the required slurry mass fraction during leaching, concentration is typically performed before leaching. Both the leached slurry and the slurry after chemical precipitation require solid-liquid separation to meet the requirements of subsequent operations. This solid-liquid separation separates the solids from the liquid in the slurry. The separated solids form a filter cake or underflow, which can also be sold as a product.

[0003] A belt vacuum filter uses a circulating filter cloth or screen as a medium, positioning the slurry horizontally above the filter medium. The negative pressure and gravity provided by the vacuum equipment enable rapid and continuous separation of solids and liquids. It continuously performs automated operations such as filtration, washing, dehydration, unloading, and filter cloth regeneration, offering high production efficiency, excellent washing results, and flexible and easy operation and maintenance. After a period of use, the filter cloth requires cleaning to prevent clogging. This can be accomplished by using a high-pressure nozzle to clean the belt and filter cloth, preventing clogging that could affect the normal operation of the device.

[0004] Most existing filter cloth cleaning devices use high-pressure water flushing, but most of the existing high-pressure water flushing is fixed in a fixed position, which is not convenient for position adjustment according to the flushing situation, resulting in poor flushing conditions in some positions. Over time, the water permeability of the filter cloth becomes worse and worse, which has a certain impact on the subsequent use of the filter cloth. Utility Model Content

[0005] In view of the shortcomings of existing filter cloth cleaning devices, most of which use fixed-position high-pressure water flushing, which is inconvenient to adjust the position according to the flushing situation, the applicant provides a rationally structured automatic walking flushing device for the filter, which can realize filter cloth flushing with a movable and timed high-pressure water gun plate, thereby improving the cleaning efficiency.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A filter automatic walking flushing device includes a mounting gantry, which is arranged on one side of the belt filter. The mounting gantry includes a first crossbeam and a second crossbeam arranged in parallel laterally. A first slider is provided on the upper surface of the first crossbeam, a track is provided on the upper surface of the first crossbeam, a lead screw is provided above the track along the length direction, the first slider is provided on the lead screw, and the lead screw is driven by a corresponding first motor to drive the first slider to move horizontally and linearly, a flushing mechanism is provided above the first slider, a second slider is provided on the upper surface of the second crossbeam, a supporting mechanism is provided on the second slider, and the supporting mechanism and the water pipe cooperate with each other to move.

[0008] As a further improvement of the above technical solution:

[0009] The first crossbeam is located at the first layer where the door frame is installed, and the second crossbeam is located at the second layer where the door frame is installed.

[0010] A second motor is provided at one end of the second beam. The second motor adopts a linear drive motor. The output end of the second motor is connected to the side surface of the second slider through a connecting shaft. The second motor drives the second slider to perform horizontal linear motion in the slideway.

[0011] The first motor and the second motor are electrically connected to the PLC control system. The PLC control system controls the position of the flushing mechanism driven by the first motor and feedback controls the position of the supporting mechanism driven by the second motor.

[0012] The supporting mechanism comprises a base and two spaced-apart limiting pulleys on the base. The water pipe passes through the two spaced-apart limiting pulleys of the supporting mechanism and is limited therein.

[0013] A water tank is provided on the lower surface of the second cross beam, a water outlet of the water tank is connected to a water pipe, and the water tank is connected to a high-pressure water pump.

[0014] The flushing mechanism includes a water gun plate and a mounting side plate. The bottom of the mounting side plate is mounted on the first sliding block. The mounting side plate is located on both sides of one end of the water gun plate and is pivotally connected with the water gun plate.

[0015] The interior of the water gun plate includes a collecting channel, a water inlet pipe and a water outlet hole. The inlet of the water inlet pipe is connected to the external water pipe. The water inlet pipe is connected to the collecting channel inside the water gun plate. Several water outlet holes are arranged in a row on the internal bottom plate of the collecting channel.

[0016] The water outlet hole extends downward through the water gun plate to form a water spray hole, and the filter cloth of the belt filter is sprayed and cleaned through the water spray hole.

[0017] A corresponding buffer baffle is provided on the side of the water outlet, and the buffer baffle is located vertically in the direction of the water outlet toward the water inlet pipe to buffer and block the water flow.

[0018] The beneficial effects of the utility model are as follows:

[0019] This utility model improves upon the existing fixed-position high-pressure water guns with a movable, timed high-pressure water gun plate for filter cloth flushing, significantly improving cleaning efficiency, effectively protecting the filter cloth, and conserving water resources. By equipping the high-pressure water gun plate with an automated travel mechanism and other supporting measures, this utility model significantly prevents and reduces blockage of the filter cloth in the belt filter, achieving a more optimized effect. The utility model incorporates a water pipe support mechanism, which eliminates the drawbacks of pipe drag and entanglement caused by the movement of the high-pressure water gun plate, which in turn occupies the working space of the belt filter.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] The present invention is described more fully below with reference to the accompanying drawings, which illustrate various aspects of the present invention. The present invention may be implemented in various forms and should not be construed as limited to the various aspects of the present invention presented in this implementation section. Unless otherwise defined, all terms used herein (including industry terms) have the same meanings as commonly understood by persons of ordinary skill in the art to which the present invention pertains.

[0027] Various aspects of the present invention will be described below with reference to the accompanying drawings, which are schematic illustrations of idealized configurations of the present invention. As such, variations in the shapes of these illustrations are to be expected, for example, as a result of manufacturing techniques and / or tolerances. The various aspects of the present invention shown in the drawings may not necessarily be drawn to scale. Furthermore, some of the drawings have been simplified for the sake of clarity. Consequently, the drawings may not depict all of the various components of a given apparatus (e.g., device) or method. Therefore, the components shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the components and are not intended to limit the scope of the present invention.

[0028] Reference Figures 1 to 4 As shown, the automatic walking flushing device for the filter described in the utility model includes a mounting gantry 1, which is arranged on one side of the belt filter and arranged along the length direction of the filter cloth of the belt filter. The mounting gantry 1 includes a first crossbeam 2 and a second crossbeam 3 arranged in parallel with each other. The first crossbeam 2 is located on the first layer of the mounting gantry 1, and the second crossbeam 3 is located on the second layer of the mounting gantry 1. A first slider 4 is provided on the upper surface of the first crossbeam 2, and a track is provided on the upper surface of the first crossbeam 2. A lead screw is provided above the track along the length direction. The first slider 4 is provided on the lead screw, and the lead screw is driven by a corresponding first motor to drive the first slider 4 to move horizontally and linearly. A flushing mechanism 5 is provided above the first slider 4. The flushing mechanism 5 can spray water onto the surface of the filter cloth to clean the filter cloth of the belt filter.

[0029] A second slider 6 is mounted on the upper surface of the second crossbeam 3. A slideway is provided on the upper surface of the second crossbeam 3. The second slider 6 is positioned within the slideway, and a supporting mechanism 7 is provided on the second slider 6. A second motor is mounted at one end of the second crossbeam 3. This second motor is a linear drive motor, and its output end is connected to the corresponding side surface of the second slider 6 via a coupling shaft. The second motor drives the second slider 6 to perform horizontal linear motion within the slideway.

[0030] The supporting mechanism 7 includes a base and two limiting pulleys 8 arranged in pairs on the base. Preferably, the two limiting pulleys 8 are located at the same horizontal height. A water tank 9 is provided on the lower surface of the second crossbeam 3. The water source is stored in the water tank 9. The water outlet of the water tank 9 is connected to the water pipe 10. When the extended end of the water pipe 10 reaches the supporting mechanism 7, it passes between the two limiting pulleys 8 of the supporting mechanism 7. The water pipe 10 is limited therein by the two limiting pulleys 8. The water pipe 10 is pulled as the supporting mechanism 7 moves horizontally and moves with the supporting mechanism 7. The extended end of the water pipe 10 finally reaches the flushing mechanism 5 and is interconnected with the flushing mechanism 5 to supply water to the flushing mechanism 5. The water tank 9 is connected to a high-pressure water pump. When the high-pressure water pump injects water into the water tank 9, the water flow in the water pipe 10 generates high pressure, so that the flushing mechanism 5 forms a high-pressure water gun plate 11.

[0031] The first and second motors are both electrically connected to a PLC control system. The PLC control system controls the position of the flushing mechanism 5 driven by the first motor and provides feedback control over the position of the support mechanism 7 driven by the second motor, ensuring that the water pipe 10 remains approximately taut as the support mechanism 7 moves. The PLC control system allows for positioning and movement of the first motor, including control over the start time and duration of movement. The first motor, in conjunction with the first slider 4, and the second motor, in conjunction with the second slider 6, form an automatic travel mechanism for the high-pressure water gun plate 11, enabling automatic travel control of the high-pressure water gun plate 11.

[0032] The flushing mechanism 5 includes a water gun plate 11 and a mounting side plate 12. The bottom of the mounting side plate 12 is mounted on the first slider 4. The mounting side plate 12 is located on both sides of one end of the water gun plate 11. It is pivotally connected to the water gun plate 11 through a screw and a knob. The water gun plate 11 can be tightened or loosened by the knob, thereby adjusting and fixing the angle of the water gun plate 11.

[0033] The interior of the lance plate 11 includes a collecting channel 13, an inlet pipe 14, a water outlet 15, and a buffer baffle 16. The inlet pipe 14 is located inside the lance plate 11, near the end where the lance plate 11 mates with the mounting side plate 12. The inlet of the water inlet pipe 14 is interconnected with the external water pipe 10. The water inlet pipe 14 is interconnected with the collecting channel 13 inside the lance plate 11. The collecting channel 13 is the main area inside the lance plate 11. The collecting channel 13 is a rectangular chamber used to collect water. The inner bottom plate of the collecting channel 13 is provided with a number of water outlets 15 arranged in a row. The water outlets 15 extend downward through the lance plate 11 to form spray holes, which spray and clean the filter cloth of the belt filter. A corresponding buffer baffle 16 is provided on the side of the water outlet 15. The buffer baffle 16 is located perpendicular to the water outlet 15 in the direction toward the inlet pipe 14, buffering and blocking the water flow reaching the water outlet 15.

[0034] During implementation, the present invention is initially positioned on one side of the belt filter, extending along the length of the filter cloth. A first slider 4 is mounted on the upper surface of the first crossbeam 2, and a flushing mechanism 5 is positioned above the first slider 4. When the flushing mechanism 5 needs to be moved, the PLC control system positions and moves the first motor according to operating instructions. The first motor then drives the first slider 4 and flushing mechanism 5 in a horizontal, linear motion. The flushing mechanism 5 sprays water onto the filter cloth surface, cleaning it.

[0035] A second slider 6 is mounted on the upper surface of the second crossbeam 3, and a support mechanism 7 is mounted on the second slider 6. The support mechanism 7 includes two spaced-apart limiting pulleys 8, between which the water pipe 10 is restrained. The water pipe 10 is pulled along with the horizontal linear movement of the support mechanism 7, moving with it. While the first motor drives the first slider 4 and the flushing mechanism 5 to move horizontally and linearly, the PLC control system controls the position of the flushing mechanism 5 driven by the first motor, and provides feedback control over the position of the support mechanism 7 driven by the second motor, ensuring that the water pipe 10 remains approximately taut as the support mechanism 7 moves.

[0036] The utility model significantly reduces and prevents the filter cloth of the belt filter from clogging by configuring the high-pressure water gun plate 11 with an automatic travel device and other supporting measures, achieving a more optimized effect. The utility model is provided with a support mechanism 7 for the water pipe 10, which can solve the problem of the water pipe 10 being dragged and entangled during the movement of the high-pressure water gun plate 11, thereby occupying the working space of the belt filter.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. 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.
