[0025] Example
[0026] The detachable multi-stage filter bag structure provided in this embodiment, as shown in Figures 1-4, includes an installation box 1. A sealing cover 2 is provided on the top of the installation box 1. A filter bag grading installation mechanism 6 is provided inside the installation box 1 and below the sealing cover 2. A first threaded connector 5 is connected to the top of the sealing cover 2, and a second threaded connector 7 is connected to the bottom of the installation box 1. The installation box 1 and the sealing cover 2 are used to install the filter bag grading installation mechanism 6. The first threaded connector 5 and the second threaded connector 7 are used to connect the whole to an external object conveying pipeline, so that the object is sent into the installation box 1 and filtered by the filter bag grading installation mechanism 6. The filter bag grading installation mechanism 6 enables multi-stage installation of filter bags, thereby achieving multiple filtrations of the object and increasing the filtration effect. At the same time, the sealing cover 2 is convenient to remove from the installation box 1, so that the filter bag grading installation mechanism 6 can be removed and the filter bags installed inside the filter bag grading installation mechanism 6 can be removed.
[0027] The filter bag grading and installation mechanism 6 includes a first barrier ring 608 fixedly installed inside the cavity of the installation housing 1, a second barrier ring 606 fixedly installed inside the installation housing 1 and below the first barrier ring 608, a second mounting base plate 602 disposed on the top of the second barrier ring 606, a first mounting base plate 601 disposed on the top of the first barrier ring 608, and evenly distributed connecting pipe heads 603 communicating between the bottom of the first mounting base plate 601 and the second mounting base plate 602. The area of the first mounting base plate 601 is larger than the area of the second mounting base plate 602, and the area of the second barrier ring 606 is larger than the area of the first barrier ring 606. The area of the first mounting plate 602 is such that by setting the area of the second barrier ring 606 to be larger than the area of the first barrier ring 608, and by setting the area of the first mounting plate 601 to be larger than the area of the second mounting plate 602, it is convenient to allow the second mounting plate 602 to penetrate to the bottom of the first barrier ring 608. At the same time, it allows the second mounting plate 602 to contact the second barrier ring 606 to achieve a seal. The arrangement of the first mounting plate 601 and the second mounting plate 602 is used to install the connecting pipe head 603. The arrangement of the connecting pipe head 603 is used to install the dust collection bag to facilitate subsequent filtration of objects.
[0028] Four connecting rods 604 are fixedly installed at the bottom of the sealing cover 2. The bottom of the connecting rods 604 passes through the first mounting base plate 601 and is fixedly connected to the top of the second mounting base plate 602. The first bolt 4 is used to fix the first mounting base plate 601 and the second mounting base plate 602 relative to the bottom of the sealing cover 2. At the same time, the first mounting base plate 601 and the second mounting base plate 602 can be removed from the inside of the mounting box 1 through the sealing cover 2, so as to replace the filter bag sleeved on the outside of the connecting pipe head 603.
[0029] A second rubber sealing ring 607 is fixedly installed on the top of the first barrier ring 608. The top of the second rubber sealing ring 607 contacts the bottom of the first mounting base 601. The second rubber sealing ring 607 increases the seal between the first mounting base 601 and the first barrier ring 608, allowing objects to be discharged through the connecting pipe head 603 inside the first mounting base 601 and thus achieve filtration through the filter bag.
[0030] The top of the second barrier ring 606 is provided with a third rubber sealing ring 609. The top of the third rubber sealing ring 609 contacts the bottom of the second mounting base plate 602. The third rubber sealing ring 609 is provided to increase the seal between the second mounting base plate 602 and the second barrier ring 606, thereby enabling the object to be discharged through the connecting pipe head 603 inside the second mounting base plate 602 to achieve filtration.
[0031] The sealing cover 2 has a groove 8 inside, and four second bolts 9 are inserted inside the groove 8. The bottom of the second bolts 9 penetrates into the interior of the mounting box 1 and is connected to the mounting box 1 by threads. The groove 8 is used to accommodate the second bolts 9, and the second bolts 9 are used to fix the sealing cover 2 relative to the mounting box 1. At the same time, by removing the second bolts 9, the sealing cover 2 and the filter bag grading installation mechanism 6 can be removed to replace the filter bag.
[0032] The installation housing 1 is equipped with a first rubber sealing ring 605. The top of the first rubber sealing ring 605 contacts the bottom of the sealing cover 2. The first rubber sealing ring 605 is used to increase the seal between the sealing cover 2 and the installation housing 1, and to prevent substances from leaking out through the installation housing 1 and the sealing cover 2.
[0033] Mounting brackets 3 are fixedly installed on both sides of the mounting box 1. Two first bolts 4 are interspersed inside the mounting brackets 3. The mounting brackets 3 and the first bolts 4 are used to install and fix the mounting box 1.
[0034] In use, this device is suitable for filtering liquids or gases. In actual use, first, according to the desired location, install the mounting housing 1 to the required position using the mounting bracket 3 and the first bolt 4. After installation, connect the gas or liquid guide pipe and discharge pipe to the first threaded connector 5 and the second threaded connector 7, respectively. After connection, the liquid or gas to be filtered is sent into the interior of the mounting housing 1. After entering the interior of the mounting housing 1, the liquid or gas is located at the top of the first mounting base 601, and is discharged through the connecting pipe 603 inside the first mounting base 601. It is then filtered through the filter bag located at the bottom of the connecting pipe 603. After filtration, it is further filtered through the second mounting base 602 and the connecting pipe 603 and filter bag at the bottom of the second mounting base 602. The second threaded connector 7 is discharged. When the filter bag needs to be replaced, the sealing cover 2 is pulled out from the top of the mounting box 1 by unscrewing the second bolt 9. Then, the first mounting base plate 601 and the second mounting base plate 602 installed at the bottom of the sealing cover 2 are taken out. The filter screen sleeved on the outside of the connecting pipe head 603 is removed, and a new filter screen is sleeved on the outside of the connecting pipe head 603 and tied. The first mounting base plate 601 and the second mounting base plate 602 are inserted into the interior of the mounting box 1 and contact the first blocking ring 608 and the second blocking ring 606. The sealing cover 2 is fixed to the top of the mounting box 1 by the second bolt 9. Since this solution can filter liquids or gases, the filter bag is not specifically disclosed in this utility model. The specific model of the filter bag can be replaced according to the specific use.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
