DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0023] This embodiment provides a filtering device for the chemical industry, such as Figure 1-5 As shown, the filtering device includes a bag filter body 1 and a liquid inlet 2 arranged on the outside of the bag filter body 1, a liquid discharge port 3 is installed at the lower end of the bag filter body 1, a sealing top cover 4 is provided at the upper end of the bag filter body 1, and a filter bag 6 is provided inside the bag filter body 1;
[0024] A filtering mechanism 5 is provided inside the bag filter body 1;
[0025] The filtering mechanism 5 includes a limiting ring 52 installed inside the bag filter body 1, a perforated shaping cylinder 51 is provided on the inner side of the limiting ring 52, a fixing ring 53 is installed on the upper end of the perforated shaping cylinder 51, and a mounting ring 61 for overlapping with the fixing ring 53 is fixedly installed on the filter bag 6. A positioning bracket 7 is installed inside the bag filter body 1, and an electric vibrator 71 for connecting with the lower end of the perforated shaping cylinder 51 is provided on the upper end of the positioning bracket 7. Several groups of positioning holes 62 are opened on the mounting ring 61.
[0026] Specifically, the through-hole shaping cylinder 51 is a stainless steel structure with a cylindrical shape and an array of liquid-permeable holes. This structure is used to position the filter bag 6, which can not only provide shaping for the filter bag 6 but also avoid wrinkles in the filter bag 6 during vibration. The mounting ring 61 installed on the filter bag 6 has a positioning hole 62. When the filter bag 6 is installed on the fixing ring 53, multiple pins can be used to ensure that the filter bag 6 will not detach during the up and down vibration. The positioning bracket 7 is composed of multiple racks and plays a role in installing and positioning the electric vibrator 71. The use of multiple racks will not affect the normal drainage of the drain port 3.
[0027] A movable ring 57 is sleeved on the outside of the perforated shaping cylinder 51, and a movable groove 521 for the longitudinal movement of the movable ring 57 is opened on the limiting ring 52. There are several telescopic rods 54 in a circular array on the limiting ring 52, and the end of the telescopic rod 54 away from the limiting ring 52 is fixedly connected to the fixed ring 53.
[0028] More specifically, the movable ring 57 installed on the perforated shaping cylinder 51 cooperates with the movable groove 521 opened in the limiting ring 52, so that there will be no tilting during the up and down movement of vibration, and it can prevent liquid leakage. The telescopic rod 54 between the fixed ring 53 and the limiting ring 52 and the spring 55 mounted on the telescopic rod 54 can reduce the intensity of vibration and provide protection for the filter bag 6.
[0029] Several groups of springs 55 for sleeved on the telescopic rod 54 are provided between the fixing ring 53 and the limiting ring 52 , and a sealing gasket 56 is fixedly mounted on the limiting ring 52 .
[0030] It should be noted that the sealing gasket 56 plays a role in sealing and preventing liquid leakage when the through-hole shaping cylinder 51 moves up and down.
[0031] During use, a perforated shaping cylinder 51 is designed inside the bag filter body 1 to shape and position the filter bag 6. The movable groove 521 opened by the limiting ring 52 cooperates with the movable ring 57 installed on the outer wall of the perforated shaping cylinder 51. When the electric vibrator 71 on the positioning bracket 7 is started, the perforated shaping cylinder 51 will be driven to move up and down. At the same time, the perforated shaping cylinder 51 will vibrate up and down synchronously with the filter bag 6. During the high-frequency vibration process, impurities attached to the filter holes of the filter bag 6 will float to avoid clumping and clogging of the filter holes. In this way, the filter bag 6 can be taken out and cleaned in a short period of time without pausing the equipment, thereby improving the filtration efficiency of impurities in the liquid.
