Description

Technical Field

[0001] The utility model belongs to the technical field of dry-type filter cabinets, and in particular relates to a quick-detachable dry-type filter cabinet. Background Art

[0002] The dry filter is an exhaust gas pre-treatment device that filters out dust particles and water mist particles in the exhaust gas flow. The filter cabinet consists of an equipment housing, a quick-opening operation door, a bag filter, bolt fasteners, a differential pressure measuring instrument, etc. The exhaust gas containing dust particles and water mist particles enters through the air inlet, and after being filtered by a single-stage or multi-stage air filter, the clean exhaust gas flow is discharged from the air outlet.

[0003] After a certain period of operation, a thick layer of dust will gradually accumulate on the surface of the bag filter. The deposition of dust not only affects the filtration efficiency, but also significantly increases the pressure difference at both ends of the filter, thus affecting the smooth operation of the entire system. In order to restore the normal performance of the equipment and ensure the cleanliness of the production environment, regular manual replacement and deep cleaning work become particularly critical.

[0004] However, the current bolt fastening method faces many inconveniences when performing filter disassembly and assembly operations. First, the process of tightening and loosening the bolts one by one is cumbersome and time-consuming, which increases the labor intensity of maintenance personnel; second, since filters are often installed in relatively compact or difficult-to-reach spaces, the space limitations of disassembly and assembly operations further increase the difficulty of operation, and may even prolong downtime and affect production efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a quick-release dry filter cabinet, which aims to solve the many inconveniences faced by the current bolt fastening method when performing filter disassembly and assembly operations. First, the process of tightening and loosening the bolts one by one is cumbersome and time-consuming, which increases the labor intensity of maintenance personnel; secondly, since the filter is often installed in a relatively compact or difficult-to-reach space, the space limitation of the disassembly and assembly operation further increases the difficulty of operation, and may even prolong downtime and affect production efficiency.

[0006] To achieve the above object, the utility model provides the following technical solutions: a quick-detachable dry filter cabinet, comprising a shell, one side of which is provided with three quick-opening doors, an installation panel is installed inside the shell, a bag filter is installed in the inner cavity of the installation panel, and inner grooves are provided on the outer walls on both sides of the inner cavity of the installation panel;

[0007] A compression spring is installed in the inner groove, a pull rod is movably sleeved inside the compression spring, one end of the pull rod is connected to a nut, a pull ring is installed at the other end of the pull rod, and a cross bar is movably installed through the outer wall of the pull rod at one end close to the pull ring.

[0008] In order to allow one end of the pull rod to be located inside the inner groove and easily detached, as a preferred quick-detachable dry filter cabinet of the utility model, one end of the pull rod is integrally designed with a threaded head, and the threaded head is threadedly connected to the nut.

[0009] In order to ensure that the compression spring and the nut will not fall out of the inner groove, as a preferred quick-detachable dry filter cabinet of the utility model, the inner diameter of the opening end of the inner groove is smaller than the maximum diameter of the compression spring and the nut, and the inner wall of the opening end of the inner groove is in active contact with the outer wall of the pull rod.

[0010] In order to enable the cross bar to squeeze and fix the bag filter in the inner cavity of the installation panel, as a preferred embodiment of the utility model, a quick-detachable dry filter cabinet has one end of the cross bar movably contacting with the outer wall of the bag filter.

[0011] In order to enable the pull rod to squeeze the cross bar onto the outer wall of the bag filter under the restoring action of the compression spring, a quick-detachable dry filter cabinet is preferably provided with a circular limiting pad on the outer wall of one end of the pull rod close to the pull ring, and the pull rod is squeezed onto the outer wall of the cross bar through the circular limiting pad.

[0012] In order to prevent the nut from rotating synchronously with the pull rod when the pull rod rotates, as a preferred quick-detachable dry filter cabinet of the utility model, a limit strip is fixedly installed on the inner walls on both sides of the horizontal center dividing line of the inner groove, and the through grooves on both sides of the nut are movably connected to a limit strip.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] A compression spring is installed on the back of the installation panel of this solution, and the compression spring is connected to the bag filter fixing code on the front through a pull rod. The reverse force generated by the compression spring forces the cross bar to fix the bag filter on the installation panel. When removing the bag filter, pull the pull ring on the pull rod to release the compression structure of the cross bar on the bag filter, making the removal of the bag filter very simple.

[0022] 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.

[0023] See also Figure 1-5 The utility model provides the following technical solutions: a quick-detachable dry filter cabinet, comprising a shell 1, three quick-open doors 2 are installed on one side of the shell 1, a mounting panel 3 is installed inside the shell 1, a bag filter 4 is installed in the inner cavity of the mounting panel 3, and inner grooves 5 are opened on the outer walls on both sides of the inner cavity of the mounting panel 3;

[0024] A compression spring 6 is installed in the inner groove 5, and a pull rod 7 is movably sleeved inside the compression spring 6. One end of the pull rod 7 is connected to the nut 8, and a pull ring 9 is installed at the other end of the pull rod 7. A cross bar 10 is also movably installed on the outer wall of the end of the pull rod 7 close to the pull ring 9.

[0025] Preferably: one end of the pull rod 7 is integrally designed with a thread head 701, the thread head 701 is threadedly connected with the nut 8, the inner diameter of the open end of the inner groove 5 is smaller than the maximum diameter of the compression spring 6 and the nut 8, and the inner wall of the open end of the inner groove 5 is in active contact with the outer wall of the pull rod 7. One end of the cross bar 10 is in active contact with the outer wall of the bag filter 4. A circular limit pad is provided on the outer wall of the pull rod 7 near the pull ring 9, and the pull rod 7 is squeezed on the outer wall of the cross bar 10 through the circular limit pad.

[0026] During specific use, the pull rod 7 will form a threaded locking structure with the nut 8 through the threaded head 701. When the compression spring 6 is reset, the nut 8 will be pushed toward one side of the inner groove 5. When the nut 8 moves, it will drive the pull rod 7 to move toward the inside of the inner groove 5. As a result, one end of the pull rod 7 can squeeze and fix the cross bar 10 on the outer wall of one side of the bag filter 4.

[0027] Preferably, a limiting strip 11 is fixedly mounted on the inner walls on both sides of the transverse center dividing line of the inner groove 5 , and the through grooves on both sides of the nut 8 are movably connected to a limiting strip 11 .

[0028] During specific use, the angle of the pull rod 7 in the inner groove 5 is adjusted, and the nut 8 at one end of the pull rod 7 is pressed against one end of the two limit strips 11. As the pull rod 7 is adjusted, one end of the nut 8 will also rotate on the outer wall of one end of the two limit strips 11. When the through groove on the nut 8 is aligned with the corresponding limit strip 11, the nut 8 is further pushed into the inner groove 5 through the pull rod 7. When the nut 8 is stuck between the two limit strips 11, rotating the pull rod 7 can make the pull rod 7 move independently into the inner groove 5. This will also reduce the distance between the nut 8 and the inner groove 5, thereby increasing the extrusion force on the compression spring 6. In this way, the reverse force of the compression spring 6 on the pull rod 7 during use will also increase. Therefore, the extrusion strength of the pull rod 7 on the cross bar 10 can be adjusted through this structure during use to improve the firmness of the bag filter 4 during installation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
