Description

Technical Field

[0001] The present invention relates to the technical field of filter presses, and specifically, it is a quick-opening circular plate diaphragm filter press. Background Art

[0002] The quick-opening circular plate diaphragm filter press is a highly efficient and highly automated solid-liquid separation device, mainly used in the filtration processes of industries such as sludge dewatering, mining, chemical engineering, and food. Its core features lie in the "quick-opening" design and the "diaphragm pressing" function, significantly improving the filtration efficiency and the moisture content of the filter cake.

[0003] During the filtration process of different materials, their characteristics such as particle size, concentration, and viscosity are different. It is difficult for the prior art to adjust the aperture size of the drainage holes and the discharge speed of the filtrate, resulting in an unsmooth filtration process, reducing the filtration efficiency, and it is difficult to reduce the probability of blockage for some drain pipes during use.

[0004] Finally: When the existing quick-opening circular plate diaphragm filter press realizes quick opening through a chain, during the filtration process, the filter plate group may be unevenly pressed, increasing the leakage caused by uneven pressure during the filtration process. It is difficult to complete all the filtration in one single press.

[0022] Embodiment 1:

[0023] Please refer to Figures 1 to 3 , a quick-opening circular plate diaphragm filter press of the present invention includes a mounting frame 1. A pressing seat 2 is slidably connected inside the mounting frame 1. A filter pressing and drainage mechanism 3 is slidably connected inside the mounting frame 1. A first connecting block 4 is fixedly connected to the left end of the filter pressing and drainage mechanism 3. A mounting shell 5 is fixedly connected to the front end of the mounting frame 1. A quick-opening mechanism 6 is fixedly connected to the right front end of the mounting shell 5. A transmission member 7 is provided on the right side of the mounting frame 1. A control mechanism 8 is fixedly connected to the right rear end of the mounting shell 5. The filter pressing and drainage mechanism 3 is arranged on the left side of the mounting frame 1. The control mechanism 8 is electrically connected to the transmission member 7.

[0024] The filter pressing and drainage mechanism 3 includes a circular plate diaphragm 31. The circular plate diaphragm 31 is slidably connected inside the mounting frame 1. Two sealed pressing chambers 32 are provided inside the circular plate diaphragm 31. The pressing chambers 32 are connected to both sides of the pressing holes 33. The pressing chambers 32 are convenient for conveying liquid.

[0025] A pressing joint 34 is provided below the outer wall of the pressing hole 33, and a rubber sealing ring 35 is fixedly connected to the upper part of the pressing hole 33. A ceramic coating 36 is sprayed inside the rubber sealing ring 35, and a silicone coating 37 is sprayed inside the ceramic coating 36. The silicone coating 37 is convenient for effectively protecting the outer surface of the airbag 38.

[0026] An airbag 38 is fixedly connected inside the organic silicon coating 37. The rubber sealing ring 35, the ceramic coating 36, the organic silicon coating 37 and the front end of the airbag 38 are all provided with connecting holes 39.

[0027] The connecting hole 39 is connected to an external gas conveying device, and a sealing ring is provided at the connection between the connecting hole 39 and the external gas conveying device. The interior of the pressing hole 33 is conical.

[0028] The working principle of a quick-opening circular plate diaphragm filter press based on the first embodiment is: First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation; Second, the staff transports the material into the filter press through external equipment. When the filter press is full of material, the filter press starts to work. The filter press uses the pressure of the transmission member 7 to separate the solid and the liquid, so that the liquid is transported to the pressing hole 33 through the pressing chamber 32, and then transported to the outside through the pressing hole 33. The conical setting of the pressing hole 33 is used to prevent blockage. Third, when the aperture of the pressing hole 33 needs to be adjusted, the staff connects the external gas delivery device to the connecting hole 39, thereby delivering the external gas to the airbag 38 through the external gas delivery device, and adjusting the aperture of the pressing hole 33 by inflating the airbag 38. During the use of the airbag 38, the good corrosion resistance and wear resistance of the silicone coating 37 are firstly used to effectively protect the outer surface of the airbag 38, and the high hardness and wear resistance of the ceramic coating 36 are used to further improve the wear resistance of the airbag 38 to form a second layer of protective film. Finally, the rubber sealing ring 35 is installed at the connection between the airbag 38 and the connecting hole 39 to fill the small gap between the two to a certain extent, thereby reducing the possibility of gas leakage.

[0029] Embodiment 2:

[0030] See also Figure 4 Compared with the first embodiment, the quick-opening circular plate diaphragm filter press of the present invention further includes: a quick-opening mechanism 6, the quick-opening mechanism 6 includes a motor 61, the right front end of the mounting shell 5 is fixedly connected with the motor 61, the left end of the output shaft of the motor 61 is fixedly connected with a multi-stage screw 62, and the front end of the mounting shell 5 is fixedly connected with a limiting rod 63, which facilitates the limiting movement of the protrusion 67.

[0031] The multi - stage screw 62 penetrates through the sleeve 64 and is threadedly connected to its interior. A first electromagnetic block 65 is fixedly connected to the outer wall of the sleeve 64. The outer wall of the first electromagnetic block 65 is magnetically adsorbed to the sliding groove 66. The sliding groove 66 is provided on the right side of the convex block 67. The top of the convex block 67 is fixedly connected to a detection mechanism 68. The convex block 67 facilitates the installation and fixation of the detection mechanism 68.

[0032] A sliding block 69 is fixedly connected to the back of the convex block 67. The back of the sliding block 69 is slidably connected to the sliding groove plate 610. Five groups of second electromagnetic blocks 611 are equidistantly arranged in the sliding groove plate 610. The multi - stage screw 62 is rotatably connected to the rear end inside the installation shell 5. The second electromagnetic blocks 611 facilitate driving the sliding block 69 to move.

[0033] The first electromagnetic block 65 is electrically connected to an external current output device. The outer wall of the first electromagnetic block 65 is slidably connected to the sliding groove 66. The limiting rod 63 penetrates through the convex block 67 and is slidably connected to its interior. The second electromagnetic blocks 611 are electrically connected to an external current output device. The second electromagnetic blocks 611 are magnetically adsorbed to the sliding block 69. There are twenty - four groups of first connection blocks 4, and three groups of sliding groove plates 610 are equidistantly arranged at the front ends of the twenty - four groups of first connection blocks 4.

[0034] In this embodiment: First, when it is necessary to pull the circular plate diaphragm 31 at one time, start the motor 61. The motor 61 drives the multi - stage screw 62 to rotate. The multi - stage screw 62 drives the three convex blocks 67 to move leftward through the sleeve 64 and in cooperation with the limiting rod 63. The three convex blocks 67 drive the three sliding blocks 69 to move leftward. The three sliding blocks 69 drive the three sliding groove plates 610 to move leftward through magnetic adsorption with the second electromagnetic blocks 611. The three sliding groove plates 610 drive multiple circular plate diaphragms 31 to be pulled at one time through the first connection blocks 4, reducing the uneven pressure on the circular plate diaphragm 31 and the leakage caused by uneven pressure during the pressure filtration process when the quick - opening type is realized through a chain in the prior art. Second, when it is necessary to adjust the position of the convex block 67, drive the five second electromagnetic blocks 611 to work through an external current output device and stop the first electromagnetic block 65 from working, so that the sliding block 69 moves in the sliding groove plate 610 under the influence of magnetic adsorption of the five second electromagnetic blocks 611. The sliding block 69 drives the convex block 67 to move, and the convex block 67 drives the sliding groove 66 to move. At this time, the outer wall of the first electromagnetic block 65 slides with the sliding groove 66. When the position of the convex block 67 is adjusted, drive the first electromagnetic block 65 to work through an external current output device, so that the first electromagnetic block 65 fixes the moving position of the convex block 67, thereby adjusting the pressure of the circular plate diaphragm 31 according to the specific characteristics of the material.

[0035] Embodiment Three:

[0036] Please refer to Figures 5 to 6, a quick-opening circular plate diaphragm filter press of the present invention. Compared with the first embodiment, this embodiment further includes: a detection mechanism 68. The detection mechanism 68 includes a second connection block 681. The top of the convex block 67 is fixedly connected to the second connection block 681. The left rear end of the second connection block 681 is fixedly connected to an infrared ranging sensor 682. The second connection block 681 facilitates the installation and fixation of the infrared ranging sensor 682.

[0037] The left rear end of the second connection block 681 is fixedly connected to a connecting rod 683. The left end of the connecting rod 683 is fixedly connected to a filter plate 684. The left front end of the second connection block 681 is fixedly connected to an electric spring 685. Resistance strain gauges 686 are adhesively connected to the electric spring 685 in the directions of the spring wire axis of the electric spring 685 at ±45°. The second connection block 681 facilitates driving the electric spring 685 to perform stretching or contracting movements.

[0038] The electric spring 685 is electrically connected to an external power supply device. There are two groups of connecting rods 683, and the two groups of connecting rods 683 are respectively arranged on the front and rear sides of the infrared ranging sensor 682. The infrared ranging sensor 682 is electrically connected to an external display screen.

[0039] In this embodiment: When the convex block 67 moves, the convex block 67 synchronously drives the second connection block 681 to move. The infrared ranging sensor 682 is started, and the stray light in the ambient light is filtered out through the filter plate 684, so that the infrared ranging sensor 682 detects the distance between the two second connection blocks 681, thereby detecting the distance between the two convex blocks 67, and sending an electrical signal to the external display screen. Then, the electric spring 685 is powered on by the external power supply device. The electric spring 685 performs a contracting or stretching movement as the convex block 67 moves, and generates a stress field around it. This stress field will affect the resistance value of the resistance strain gauge 686. Then, the resistance strain element inside the resistance strain gauge 686 is deformed under the action of the stress, so that the user calculates the length change of the electric spring 685 through the resistance value of the resistance strain gauge 686, and re-detects the distance between the two convex blocks 67 through the length change of the electric spring 685. The distance between the two convex blocks 67 is judged through the two detection results, preventing the gap between the convex blocks 67 from being inappropriate and reducing the wear of the circular plate diaphragm 31 and other components.

[0040] The present invention provides a quick-opening circular plate diaphragm filter press through improvement. A filter pressing and draining mechanism 3 is provided. By the conical setting of the pressing holes 33, blockage prevention is achieved, and the aperture of the pressing holes 33 is adjusted by inflating the airbag 38. A quick-opening mechanism 6 is provided. The multi-segment screw 62 drives multiple groups of circular plate diaphragm plates 31 for a one-time pulling, reducing the uneven pressure on the circular plate diaphragm plates 31 when the quick-opening is achieved through a chain in the prior art and the leakage caused by uneven pressure during the filter pressing process. At the same time, by adjusting the position of the convex blocks 67, according to the specific characteristics of the material, the pressure of the circular plate diaphragm plates 31 is adjusted. A detection mechanism 68 is provided. The distance between two groups of convex blocks 67 is detected once by the infrared distance sensor 682, and then the distance between the two groups of convex blocks 67 is detected twice through the cooperation of the electric spring 685 and the resistance strain gauge 686. The distance between the two groups of convex blocks 67 is judged through the two detection results to prevent the inappropriate gap between the convex blocks 67 and reduce the wear of the circular plate diaphragm plates 31 and other components.
