Description

Technical Field

[0001] The utility model relates to the technical field of mine minerals, in particular to an easily adjustable extrusion roller device for a vacuum filter. Background Art

[0002] The main function of the squeeze roller device is to increase the dryness of the filter cake by physical squeezing. The process applies pressure to the filter cake through the squeeze roller, so that more liquid is discharged through the filter cloth, increasing the solid content of the filter cake. This method is very suitable for processing materials that require low residual moisture, such as solids in minerals, chemical products or food processing.

[0003] The existing squeezing roller uses gravity and manual adjustment to tension the filter cloth. The tension of the filter cloth depends entirely on experience and feel, and there is no specific numerical representation. To replace the filter cloth, the manual adjustment device must be removed first, and then the squeezing roller must be lifted up by manpower. This operation is time-consuming and laborious. Therefore, a vacuum filter squeezing roller device that is easy to adjust is proposed to solve the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-Figure 3 The utility model provides an embodiment: a vacuum filter extrusion roller device that is easy to adjust, including a bracket 8, which is the main supporting structure of the entire device, made of high-strength steel, and has good load-bearing capacity and stability. The left side of the bracket 8 is fixedly connected with two cylinder fixing angle irons 2, and the bottoms of the two cylinder fixing angle irons 2 are fixedly connected with cylinders 1. The cylinder fixing angle irons 2 are made of high-quality steel, and the surface is treated with anti-corrosion, and have good corrosion resistance and mechanical strength. The two cylinder fixing angle irons 2 are respectively located at the upper and lower positions on the left side of the bracket 8, and are fixed to the bracket 8 by bolts or welding to ensure the stable installation of the cylinder.

[0020] The driving end of the cylinder 1 is fixedly connected with a slider 5. When the cylinder 1 is started, it can drive the slider 5 to move. The adjacent sides of the two sliders 5 are rotatably connected with the squeezing rollers 4. The squeezing rollers 4 are the core working parts of the device. They are made of high-strength steel and the surface is precisely processed to ensure the flatness and wear resistance during the working process. Both ends of the squeezing rollers 4 are fixedly connected with bearings. The bearings are installed on one side of the slider 5 by bolts to ensure the smooth movement of the squeezing rollers 4 under the drive of the slider 5. Limiting components are provided on both sides of the left end of the bracket 8. The limiting components include two slide grooves 3. The two slide grooves 3 are respectively arranged on both sides of the left end of the bracket 8. The outer side of the slider 5 is slidably connected to the inner wall of the slide groove 3. Through the limitation of the slide groove 3, it is ensured that the slider 5 can move up and down smoothly and accurately under the drive of the cylinder 1 to adjust the position and pressure of the squeezing roller 4.

[0021] A hand-operated valve 6 is provided on one side of the bracket 8, and the air pressure of the cylinder 1 and the moving speed of the slider 5 can be controlled by manual operation. The hand-operated valve 6 is simple and easy to use, and the operator can perform precise pressure adjustment and position control as needed. A pressure regulating valve 7 is electrically connected to one side of the hand-operated valve 6, and the working pressure of the cylinder 1 can be accurately controlled through the pressure regulating valve 7 to ensure that the squeezing roller 4 can provide appropriate pressure during the working process. The pressure regulating valve 7 adopts a high-precision regulating device and has good adjustment performance and stability.

[0022] Working principle: When the equipment needs to be used, the operator first needs to adjust the pressure regulating valve 7 to reach the appropriate air pressure. The pressure regulating valve 7 controls the working pressure of the cylinder 1 to ensure that the cylinder 1 can provide sufficient power. After adjusting the pressure, the operator turns the handle of the manual valve 6 to start the cylinder 1. At this time, the cylinder 1 starts to work and drives the slider 5 to move in the slide 3. The cylinder 1 drives the slider 5 to move up and down, and the slider 5 drives the squeeze roller 4 to slide downward. The squeeze roller 4 is mounted on the slider 5 through a bearing and keeps stable rotation during the sliding process. When the squeeze roller 4 slides downward, the filter cloth is tensioned. The operator needs to observe the tension of the filter cloth. If the filter cloth is too loose, the air pressure can be increased by adjusting the pressure regulating valve 7. After increasing the air pressure, the cylinder 1 applies a greater force, so that the slider 5 drives the squeeze roller 4 to move further downward, thereby increasing the tension of the filter cloth. After adjusting to the appropriate tension of the filter cloth, the squeeze roller 4 applies uniform pressure to the filter cloth. The operator can make real-time adjustments through the hand-operated valve 6 and the pressure regulating valve 7 to ensure the pressure is stable during the extrusion process and achieve the best filter cloth tensioning effect. After the material processing is completed, the operator controls the cylinder 1 to return to its original position through the hand-operated valve 6 again, and the slider 5 drives the extrusion roller 4 to reset and leave the filter cloth. At this time, the equipment enters the standby state and is ready for the next material processing.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
