Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing equipment, in particular to a high-pressure flushing device for a feldspar concentrate filter. Background Art

[0002] Feldspar is widely distributed in the Earth's crust. As a rock-forming mineral with significant industrial value, it is widely used in industries such as glass, ceramics, and refractory materials. The higher its quality, the higher its application value. Feldspar accounts for approximately 70% of the total product volume and is the primary product. Due to its particle size and inherent properties, the product does not strongly flocculate with water. To ensure that the product does not "escape, bubble, drip, or leak" during transportation and does not pollute the environment, the product moisture content must be controlled below a certain level of 16%. The horizontal belt vacuum filter is a highly efficient solid-liquid separation device commonly used in mineral processing. It features horizontal vacuum filtration, countercurrent and parallel current washing, rapid dehydration, and convenient loading and unloading of filter cakes.

[0003] However, when a belt filter is running for a long time, the filter cloth tends to clog and harden, resulting in a significant decrease in filtration efficiency and a shortened service life. Currently, the existing method for removing debris from the filter cloth surface and interstices is to install a spray water pipe below the horizontal vacuum belt filter and above the filter cloth. Spray nozzles are evenly installed on the spray water pipe. The nozzles spray high-temperature cloth-washing water to wash the filter cloth to remove debris from the filter cloth surface and interstices. However, traditional spray nozzles are fixed and have a limited spray range, resulting in low cleaning efficiency for the filter cloth. Utility Model Content

[0004] In order to solve the problems of the above-mentioned existing belt filter, such as the filter cloth is easily clogged and hardened after long-term operation, which leads to a significant decrease in the filtration efficiency of the filter cloth and a shortened service life, the applicant provides a reasonable and effective high-pressure flushing device for feldspar concentrate filter. The high-pressure flushing device can flush the entire surface at the same time, increase the area flushed at the same time, achieve uniform flushing of the filter cloth on the entire surface, avoid incomplete local cleaning, and improve flushing efficiency.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A high-pressure flushing device for a feldspar concentrate filter is provided with a filter cloth of a belt filter, the filter cloth is circulated, the filter cloth has a horizontal working section, a flushing device is provided above the working section of the filter cloth, the flushing device includes a flushing box body, the flushing box body is connected to a water pump through a pipe, a water inlet channel, a uniform flow channel, a uniform flow pool and a buffer flow channel are provided in the flushing box body, the water inlet channel is provided inside the flushing box body near the long side of the flushing box body, the water inlet channel extends along the middle position of the uniform flow channel and is connected to the middle of the uniform flow channel through a pipe, the uniform flow channel is located on one side of the long side of the uniform flow pool and is connected to the uniform flow pool through a number of buffer flow channels, the buffer flow channels are arranged at intervals, the buffer flow channels are arranged at an angle to the uniform flow channel, and the direction of the buffer flow channel in the uniform flow channel is deviated from the middle position of the uniform flow channel.

[0007] As a further improvement of the above technical solution:

[0008] In the flushing box body, the uniform flow channel and the uniform flow pool are arranged in the same direction as the water inlet channel, and the uniform flow channel is located between the water inlet channel and the uniform flow pool.

[0009] The uniform flow pool is a rectangular parallelepiped structure with a cavity inside for holding liquid.

[0010] The direction of the buffer flow channel in the uniform flow channel enables the water flow to form a circuitous corner when flowing from the middle of the uniform flow channel to both ends and entering the buffer flow channel.

[0011] The winding corners gradually widen from the middle of the uniform flow channel to both ends.

[0012] The flow-evening pool is provided with longitudinal linear grooves and transverse linear grooves that intersect vertically and horizontally. The longitudinal linear grooves and transverse linear grooves are located on the inner bottom plate of the flow-evening pool, so that the cavity of the flow-evening pool forms a potential difference.

[0013] A water outlet hole is provided at the intersection of the longitudinal linear groove and the transverse linear groove.

[0014] A nozzle extends downward from the water outlet outside the flushing box, and water flows through the nozzle to flush the surface of the filter cloth.

[0015] An expansion interface is provided on the side of the flushing box body. The expansion interface is located at both ends of the flushing box body and communicates with the interior of the uniform flow channel. A round cover is provided at the outer end of the expansion interface.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model changes the original fixed single-point high-pressure flushing device into a high-pressure flushing device that can flush the entire surface at the same time, reducing the number of operators and increasing the area that can be flushed at the same time, thereby greatly improving the filtration efficiency. It is improved from an ordinary mobile single-unit high-pressure flushing machine to a fixed timed high-pressure flushing machine.

[0018] The utility model uses the entire surface of the filter cloth for cleaning, avoiding local high pressure and uneven water pressure distribution, which may cause deformation of the filter cloth and affect the filtering effect. The utility model can achieve uniform flushing of the entire surface of the filter cloth, avoiding the problem of partial incomplete cleaning and the need for repeated cleaning, and improving flushing efficiency.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] 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.

[0025] 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.

[0026] Reference Figures 1 to 3As shown, the high-pressure flushing device of the feldspar concentrate filter described in the utility model is arranged on a belt filter, which includes a filter cloth 1, a filter belt active roller 2, a filter belt driven roller 3, a filter belt 4, a cloth pressing roller 5, a transmission mechanism 6, a vacuum system 7 and a flushing device 13, wherein the filter cloth 1 is arranged in a circular manner, and the filter belt active roller 2, the filter belt driven roller 3 and the filter belt 4 constitute a filter belt driving mechanism for driving the filter cloth 1, the filter belt 4 is wound on the filter belt active roller 2 and the filter belt driven roller 3 and circulates on the filter belt active roller 2 and the filter belt driven roller 3, and the filter belt driving mechanism drives the filter cloth 1 to circulate, and a cloth pressing roller 5 is arranged above the filter cloth 1 at one end of the filter belt driving mechanism, and the cloth pressing roller 5 presses the filter cloth 1 on the filter belt driving mechanism, so that the filter cloth 1 is driven by the filter belt driving mechanism to move.

[0027] The filter cloth 1 forms a horizontal working section on the filter belt drive mechanism, and a transmission mechanism 6 is provided on the portion outside the working section of the filter cloth 1. The transmission mechanism 6 is used to keep the filter cloth 1 in a tensioned and correct transmission state so that it can be transmitted stably. Therefore, a tensioning device and a correction device are provided on the filter cloth 1 at the transmission mechanism 6 to keep the filter cloth 1 tensioned and correct the deviation.

[0028] A vacuum system 7 is installed on the working surface of the filter cloth 1. This system includes a filter cartridge 8, a drain separator tank 9, a vacuum pump 10, and a water pump 11. The filter cartridge 8 is positioned below the working surface of the filter cloth 1. The filter cartridges 8 are rectangular parallelepiped boxes, with several arranged side by side below the working surface of the filter cloth 1, closely fitting the bottom surface of the filter cloth 1. The interiors of the filter cartridges 8 are connected to the drain separator tank 9 via pipes. The vacuum pump 10 is connected to the drain separator tank 9 via an air pipe, and the water pump 11 is connected to the drain separator tank 9 via a water pipe. The vacuum pump 10 evacuates the interior of the drain separator tank 9, creating a negative vacuum pressure inside the transmission mechanism 6. When the filter cloth 1 is operating and slurry 12 is transported across the working surface, the liquid contained in the slurry 12 is extracted into the transmission mechanism 6, thereby dehydrating the slurry 12 as it is filtered through the filter cloth 1. The liquid flowing into the transmission mechanism 6 is pumped into the drainage separation tank 9 through the pipeline and is pumped by the water pump 11 as one of the water sources of the water pump 11 .

[0029] A flushing device 13 is provided above the working surface of the filter cloth 1. This device includes a flushing cartridge 14, which is connected to a water pump 11 via a pipeline. The water pump 11 delivers high-pressure water to the flushing cartridge 14. The flushing cartridge 14 is provided with a water inlet channel 15, a flow balancing channel 16, a flow balancing tank 17, and a buffer channel 18. The water inlet channel 15 is provided along the length of the flushing cartridge 14, near the long edge of the flushing cartridge 14. The flow balancing channel 16 and the flow balancing tank 17 are also provided in the flushing cartridge 14 in the same direction as the water inlet channel 15. The flow balancing channel 16 is located between the two channels. The water inlet channel 15 extends along the middle of the flow balancing channel 16 and is connected to the middle of the flow balancing channel 16 via a pipeline. The uniform flow pool 17 is a rectangular structure with a cavity for accommodating liquid inside. The uniform flow channel 16 is located on one side of the long side of the uniform flow pool 17 and is connected to the uniform flow pool 17 through a number of buffer channels 18. The buffer channels 18 are arranged at intervals and at an angle to the uniform flow channel 16. The orientation of the buffer channels 18 in the uniform flow channel 16 causes the water flow to form a circuitous corner when flowing from the middle of the uniform flow channel 16 to the two ends. That is, the orientation of the buffer channels 18 in the uniform flow channel 16 deviates from the middle position of the uniform flow channel 16, rather than tending to the middle position of the uniform flow channel 16. After the water flow in the uniform flow channel 16 is turned, it flows into the uniform flow pool 17. The circuitous corner gradually widens from the middle of the uniform flow channel 16 to the two ends.

[0030] The flow-leveling tank 17 is provided with intersecting longitudinal linear grooves 19 and transverse linear grooves 20. These grooves are located on the inner floor of the flow-leveling tank 17, creating a potential difference within the cavity of the flow-leveling tank 17. A water outlet 21 is provided at the intersection of the longitudinal linear grooves 19 and the transverse linear grooves 20. A nozzle extends downward from the flushing box 14, through which water flows to flush the surface of the filter cloth 1.

[0031] An expansion interface 22 is provided on the side of the flushing cartridge body 14. The expansion interface 22 is located at both ends of the flushing cartridge body 14 and communicates with the interior of the uniform flow channel 16. A round cover is provided at the outer end of the expansion interface 22 for closing the outer end of the expansion interface 22. When multiple flushing cartridge bodies 14 are connected to each other for use, they can be connected in parallel through the expansion interface 22 to achieve the effect of expanding the flushing area.

[0032] When the utility model is implemented, the filter belt active roller 2, the filter belt driven roller 3 and the filter belt 4 constitute a filter belt driving mechanism that drives the filter cloth 1. The filter belt 4 is wound on the filter belt active roller 2 and the filter belt driven roller 3 and the filter belt active roller 2 is driven by the motor to make the filter belt 4 rotate cyclically on the filter belt active roller 2 and the filter belt driven roller 3. The filter belt driving mechanism drives the filter cloth 1 to cyclically transmit. A cloth pressing roller 5 is provided above the filter cloth 1 at one end of the filter belt driving mechanism. The cloth pressing roller 5 presses the filter cloth 1 on the filter belt driving mechanism, so that the filter cloth 1 is driven by the filter belt driving mechanism to move. The filter box 8 and the filter cloth 1 slide together and fit tightly. When the vacuum system 7 starts working, a vacuum filtration area is formed on the working surface of the filter cloth 1. The slurry 12 is evenly distributed on the filter cloth 1 by the feeder. Under the action of vacuum, the liquid contained in the slurry 12 enters the filter box 8 through the filter cloth 1 and is extracted into the drainage separation tank 9. The mineral particles remaining on the filter cloth 1 are intercepted by the filter cloth 1, dehydrated and dried to form a filter cake.

[0033] A flushing device 13 is provided above the working section of the filter cloth 1. The flushing device 13 includes a flushing box 14. The flushing box 14 is connected to the water pump 11 through a pipeline. The water pump 11 delivers water at high pressure to the flushing box 14. After entering the flushing box 14, the water flows through the water inlet channel 15 to the uniform flow channel 16. Because the direction of the buffer flow channel 18 in the uniform flow channel 16 forms a circuitous corner, the water flows from the middle of the uniform flow channel 16 to the two ends, forming a circuitous corner. After the water turns, it flows into the uniform flow pool 17. The uniform flow pool 17 is provided with longitudinal linear grooves 19 and transverse linear grooves 20 that intersect vertically and horizontally. The longitudinal linear grooves 19 and transverse linear grooves 20 are located on the inner bottom plate of the uniform flow pool 17, forming a potential difference in the cavity of the uniform flow pool 17, and the water flow is further uniformed in the uniform flow pool 17. A water outlet 21 is formed at the intersection of the longitudinal linear groove 19 and the transverse linear groove 20. A nozzle extends downward from the water outlet 21 outside the flushing box 14, through which water flows to flush the surface of the filter cloth 1. When multiple flushing boxes 14 are connected to each other, they can be connected in parallel through an expansion interface 22 to expand the flushing area.

[0034] 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.
