Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and in particular to a belt filter press with good filter belt cleaning effect. Background Technology

[0002] In current mineral mining and processing, filter presses, as key equipment, play a crucial role in the efficient separation of solids and liquids from mineral slurry. Belt filter presses, in particular, are widely used in mineral processing due to their advantages such as strong continuous operation capability and large throughput. However, in actual production, a significant problem is the design deficiency in the filter belt cleaning process of existing belt filter presses:

[0003] 1. The cleaning locations of the filter belt are not arranged reasonably enough, often failing to fully cover all key areas of the filter belt, resulting in some areas having a lot of residual slurry and impurities;

[0004] 2. Most current cleaning institutions adopt static cleaning methods, that is, the cleaning brush or nozzle is fixed and the cleaning process is completed by the movement of the filter belt. This static cleaning method is not only inefficient, but also has limited cleaning effect and is difficult to completely remove stubborn stains on the filter belt.

[0005] Over time, these unremoved stains accumulate and eventually cause mud to stick to the idler rollers. Mud buildup on the rollers not only increases the equipment's operating resistance and reduces efficiency, but also affects the flatness of the filter belt, thus impacting the filtration effect. Specifically, this manifests as higher solid moisture content after filtration, reduced liquid recovery efficiency, and may even lead to equipment malfunctions and increased maintenance costs.

[0024] Reference Figure 1-3 A belt filter press with good filter belt cleaning effect includes a frame 1. An upper filter belt 2 and a lower filter belt 3 are installed on the frame 1 for mutual cooperation. A filter gap is formed between the upper filter belt 2 and the lower filter belt 3 for filter pressing the slurry. One end of the filter gap is set as the feed end, and the other end of the filter gap is set as the discharge end 4. The frame 1, as the supporting structure of the entire equipment, is made of high-strength materials to ensure the stability and durability of the equipment. The upper filter belt 2 and the lower filter belt 3 are used to cooperate to filter the slurry and achieve solid-liquid separation. The setting of the feed end and the discharge end 4 allows the slurry to smoothly enter the filter gap and be discharged from the discharge end 4 after the filter pressing is completed.

[0025] In order to support and guide the movement of the upper filter belt 2 and the lower filter belt 3, support rollers, transmission rollers, correction rollers, tension rollers and drive rollers are also installed on the frame 1 for cooperating with the upper filter belt 2 and the lower filter belt 3. A drive motor for driving the drive roller to rotate is also installed on the frame 1.

[0026] In order to effectively remove the dewatered filter cake so that the filter belt can be used in the next filter press cycle, a scraper 5 is also installed on the frame 1 at the discharge end 4 to cooperate with the upper filter belt 2 and the lower filter belt 3.

[0027] To better ensure the smooth operation of the upper filter belt 2 and the lower filter belt 3, an upper idler roller 6 is installed on the frame 1 above the upper filter belt 2 to cooperate with the upper filter belt 2, and a lower idler roller 7 is installed on the frame 1 below the lower filter belt 3 to cooperate with the lower filter belt 3. An upper cleaning mechanism 8 for cleaning the upper filter belt 2 is installed on the frame 1 between the upper idler roller 6 and the discharge end 4, and a lower cleaning mechanism 9 for cleaning the lower filter belt 3 is installed on the frame 1 between the lower idler roller 7 and the discharge end 4. The upper cleaning mechanism 8 and the lower cleaning mechanism 9 are used to clean the upper filter belt 2 and the lower filter belt 3 before they come into contact with the upper idler roller 6 and the lower idler roller 7, so as to effectively solve the problem of mud sticking to the upper idler roller 6 and the lower idler roller 7, and at the same time help to extend the service life of the upper filter belt 2 and the lower filter belt 3.

[0028] Specifically:

[0029] Both the upper cleaning mechanism 8 and the lower cleaning mechanism 9 include a fixed bracket 10 fixedly installed on the frame 1. An adjusting bracket 13 is installed on the fixed bracket 10 via an adjusting screw 11. A cleaning pipe 14 and a cleaning power device for driving the cleaning pipe 14 to swing are rotatably installed on the adjusting bracket 13. One end of the cleaning pipe 14 is set as a closed end, and the other end of the cleaning pipe 14 is connected to a cleaning water supply pipe via a rotary joint 16. Several cleaning holes 15 are also provided on the cleaning pipe 14. The fixed bracket 10 serves as a basic support, while the adjustable bracket 13 is installed via adjusting screws 11 and can be adjusted up and down as needed to adjust the position of the cleaning pipe 14, facilitating better cleaning of residues on the filter belt. Preferably, the adjusting screws 11 are vertically inserted into the fixed bracket 10, and the fixed bracket 10 has openings that mate with the adjusting screws 11. Locking nuts 12 are screwed onto the adjusting screws 11 on both the upper and lower sides of the openings. The adjustable bracket 13 is installed in the lower middle part of the adjusting screws 11, and their height can be adjusted by pulling up or down the adjusting screws 11. The locking nuts 12 are used to lock the adjusting screws 11 after the adjustment operation is completed, ensuring their reliability and stability. More preferably, there are two adjusting screws 11.

[0030] The driving device is used to drive the cleaning pipe 14 to swing back and forth to achieve dynamic cleaning of the filter belt, ensuring the uniformity and effectiveness of the cleaning. Preferably, the cleaning pipe 14 is mounted on the adjusting bracket 13 through bearings and bearing seats. The cleaning power device is a geared motor, and the motor shaft of the geared motor is connected to the cleaning pipe 14 for transmission.

[0031] In actual use, the cleaning holes 15 are arranged in 2-3 rows, and the 2-3 rows of cleaning holes 15 are staggered on the cleaning pipe 14 to ensure the uniformity and comprehensiveness of cleaning.

[0032] The actual usage process of this belt filter press is as follows:

[0033] The slurry to be processed is pumped or flows by gravity into the filter press gap through the feed end;

[0034] The slurry first passes through a relatively wide distribution zone, where most of the free water is initially separated due to gravity.

[0035] As the slurry enters the wedge zone and the pressing zone, the filter belt gradually narrows, the material is compressed, and water is further squeezed out. The pressing zone is usually equipped with rollers or other mechanical devices to increase the pressure on the material, thereby achieving more efficient dewatering.

[0036] At the discharge end 4: the scraper 5 works with the filter belt to peel the filter cake, which has been pressed and washed, off the filter belt. The peeled filter cake is then collected and processed by a collection device.

[0037] After the filter press process is completed, some slurry and water will remain on the filter belt. At this time, the cleaning mechanism will begin to clean the filter belt, specifically as follows:

[0038] The cleaning pipe 14 of the cleaning mechanism swings under the drive of the geared motor, and sprays cleaning water through the cleaning hole 15. The cleaning water is evenly sprayed on the upper filter belt 2 to wash away the residue.

[0039] The working principle of the lower cleaning mechanism 9 is the same as that of the upper cleaning mechanism 8, except that it is for cleaning the lower filter belt 3.

[0040] Secondly, the distance between the cleaning pipe 14 and the filter belt can be adjusted by adjusting the screw 11 and the locking nut 12 to better clean the filter belt.

[0041] In summary, this belt filter press is a highly efficient and flexible solid-liquid separation device. Its ingenious structural design not only ensures the smooth progress of the filtration process but also greatly improves the cleaning effect of the filter belt, effectively solving common problems such as mud sticking to the idler rollers. It is particularly suitable for slurry treatment in mining, chemical, and environmental protection fields.
