Description

Technical Field

[0001] The present invention relates to the technical field of filter presses, and in particular to 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 for filtration processes in industries such as sludge dewatering, mining, chemical engineering, and food. Its core features lie in the "quick-opening" design and the "diaphragm pressing" function, which significantly improve 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, reduced 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.

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.

[0031] 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 liquids.

[0032] A pressing joint 34 is provided below the outer wall of the pressing hole 33. A rubber sealing ring 35 is fixedly connected above the pressing hole 33. A ceramic coating 36 is sprayed inside the rubber sealing ring 35. An organosilicon coating 37 is sprayed inside the ceramic coating 36.

[0041] The multi-stage screw 62 passes through the sleeve 64 and is connected to its internal thread. The outer wall of the sleeve 64 is fixedly connected to the first electromagnetic block 65. The outer wall of the first electromagnetic block 65 is magnetically adsorbed to the slide groove 66. The slide groove 66 is arranged on the right side of the protrusion 67. The top of the protrusion 67 is fixedly connected to the detection mechanism 68. The protrusion 67 facilitates the installation and fixation of the detection mechanism 68.

[0042] The back of the protrusion 67 is fixedly connected with a sliding block 69, and the back of the sliding block 69 is slidably connected to the slide plate 610. Five groups of second electromagnetic blocks 611 are equidistantly arranged in the slide plate 610. The rear end of the mounting shell 5 is rotatably connected with a multi-section screw 62, and the second electromagnetic block 611 is convenient for driving the sliding block 69 to move.

[0043] The first electromagnetic block 65 is electrically connected to the external current output device, the outer wall of the first electromagnetic block 65 is slidably connected to the slide groove 66, the limit rod 63 passes through the protrusion 67 and is slidably connected to its interior, the second electromagnetic block 611 is electrically connected to the external current output device, the second electromagnetic block 611 is magnetically adsorbed to the sliding block 69, and the first connecting blocks 4 are provided with twenty-four groups, and three groups of slide groove plates 610 are equidistantly provided at the front end of the twenty-four groups of first connecting blocks 4.

[0044] In this embodiment:

[0045] 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 groups of bumps 67 to move leftward through the sleeve 64 and in cooperation with the limit rod 63. The three groups of bumps 67 drive the three groups of sliding blocks 69 to move leftward. The three groups of sliding blocks 69 drive the three groups of chute plates 610 to move leftward through magnetic adsorption with the second electromagnet 611. The three groups of chute plates 610 drive multiple circular plate diaphragms 31 to be pulled at one time through the first connecting block 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.

[0046] Second, when it is necessary to adjust the position of the bump 67, drive the five groups of second electromagnets 611 to work through an external current output device and stop the first electromagnet 65 from working, so that the sliding block 69 moves in the chute plate 610 under the influence of magnetic adsorption of the five groups of second electromagnets 611. The sliding block 69 drives the bump 67 to move, and the bump 67 drives the chute 66 to move. At this time, the outer wall of the first electromagnet 65 slides with the chute 66. When the position of the bump 67 is adjusted, drive the first electromagnet 65 to work through an external current output device, so that the first electromagnet 65 fixes the moving position of the bump 67, thereby adjusting the pressure of the circular plate diaphragm 31 according to the specific characteristics of the material.

[0047] Embodiment Three:

[0048] Please refer to Figures 5 to 6 , a quick-opening circular plate diaphragm filter press of the present invention.

[0049] The left rear end of the second connecting block 681 is fixedly connected with a connecting rod 683. The left end of the connecting rod 683 is fixedly connected with a filter 684. The left front end of the second connecting block 681 is fixedly connected with an electric spring 685. Resistance strain gauges 686 are respectively pasted and connected in the directions of the spring wire axis of the electric spring 685 at ±45°.

[0050] 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 distance sensor 682. The infrared distance sensor 682 is electrically connected to an external display screen.

[0051] In this embodiment:

[0052] When the protrusion 67 moves, the protrusion 67 synchronously drives the second connection block 681 to move, starts the infrared distance sensor 682, and filters out the stray light in the ambient light through the filter 684, so that the infrared distance sensor 682 detects the distance between the two groups of second connection blocks 681, thereby detecting the distance between the two groups of protrusions 67, and transmitting the electrical signal to the external display screen, and then the electric spring 685 is energized through the external power supply device. The electric spring 685 contracts or stretches with the movement of the protrusion 67, and generates a stress field around it. This stress field affects the resistance value of the resistance strain gauge 686, and then the resistance strain element inside the resistance strain gauge 686 is deformed by the stress, so that the user can calculate the length change of the electric spring 685 through the resistance value of the resistance strain gauge 686, and detect the distance between the two groups of protrusions 67 again through the length change of the electric spring 685. The distance between the two groups of protrusions 67 is judged by the two detection results, to prevent the protrusion 67 from having an inappropriate gap, and reduce the wear of the circular plate diaphragm plate 31 and other components.
