Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.

As shown in fig. 1 to 7, a cloth bag connecting and fixing structure for a cloth bag dust collector with an easily replaceable cloth bag comprises a cloth bag framework 1 and a filtering cloth bag 2, and further comprises an installation ring plate 3 and a movable clamping ring plate 4, wherein the installation ring plate 3 is fixed at the port of the cloth bag framework 1, the installation ring plate 3 and the movable clamping ring plate 4 are connected together in an assembling and disassembling mode and are circumferentially rotated and limited with each other, the filtering cloth bag 2 is fixed between the installation ring plate 3 and the movable clamping ring plate 4, and the replacement of the filtering cloth bag 2 is realized by the disassembly and the assembly of the installation ring plate 3 and the movable clamping ring plate 4;

the circumference lateral wall of installation ring board 3, activity block ring board 4 corresponds on be equipped with first screw thread installation chimb 31, second screw thread installation chimb 41, installs back together at installation ring board 3, activity block ring board 4, and first screw thread installation chimb 31, second screw thread installation chimb 41 make up into can with the dust remover in the complete screw thread installation chimb of the complete threaded connection of screw thread mounting groove. When the dust remover is used, the complete thread installation convex edge formed by the first thread installation convex edge 31 and the second thread installation convex edge 41 is installed on the dust remover body 9 through the thread, and the first thread installation convex edge 31, the second thread installation convex edge 41 and the dust remover body 9 are in threaded connection, so that the vertical displacement of the dust remover during vibration dust removal of the dust remover can be effectively prevented, and the structural stability of the dust remover is greatly improved. In addition, the first thread installation convex edge 31 and the second thread installation convex edge 41 which correspond to the installation ring plate 3 and the movable clamping ring plate 4 are in thread fit on the dust remover body 9, and due to the self-adaptive fastening fit effect of the thread and the thread, the clamping degree between the installation ring plate 3 and the movable clamping ring plate 4 is tighter, and the clamping stability between the installation ring plate 3 and the movable clamping ring plate 4 is further enhanced.

As a further improvement of the invention, the bottom of the mounting ring plate 3 and the upper end face of the movable clamping ring plate 4 are correspondingly provided with a first annular groove 32 and a second annular groove 42 which are matched with the size of the port of the filter cloth bag 2 so as to clamp and fix the filter cloth bag 2.

As a further improvement of the present invention, the groove cross section of the first annular groove 32 is a semicircular structure, and the groove cross section of the second annular groove 42 is a sector structure with a central angle corresponding to 90 °. First annular groove 32 and second annular groove 42 have constituteed the fixed ring groove that can will filter sack 2 upper end department fixed together, and through fixed ring groove's block, filter sack 2 can firmly be blocked between installation crown plate 3, activity block crown plate 4, has strengthened the stability of filtering sack 2 greatly, can not take place to drop.

As a further improvement of the invention, the left side and the right side of the mounting ring plate 3 are symmetrically provided with connecting holes 5 which penetrate through the upper part and the lower part, the upper end surface of the movable clamping ring plate 4 is correspondingly provided with a connecting rod 6 which penetrates through the connecting holes 5, and the upper end part of the connecting rod 6 which penetrates through the connecting holes 5 is provided with a fixed clamping block 7 which can rotate horizontally. According to the invention, by changing the rotation state of the fixed clamping block 7, the stability of the installation ring plate 3 and the movable clamping ring plate 4 in connection is ensured, and the installation ring plate 3 and the movable clamping ring plate 4 can be quickly installed and separated.

As a further improvement of the present invention, a first semicircular side plate 33 is disposed on the left side of the bottom of the mounting ring plate 3, a second semicircular side plate 43 is disposed on the right side of the upper end surface of the movable engaging ring plate 4, the first threaded mounting flange 31 and the second threaded mounting flange 41 are correspondingly disposed on the first semicircular side plate 33 and the second semicircular side plate 43, and the mounting ring plate 3 and the movable engaging ring plate 4 are engaged with each other in a vertically-adaptive manner.

As a further improvement of the invention, the upper end surface of the mounting ring plate 3 is also provided with a lifting handle 8 which can be flatly placed in a rotating way. The lifting handle 8 plays a role of rotating the handle to realize the installation and separation of the dust remover and the dust remover body 9 on one hand, and plays a role of lifting on the other hand, so that the dust remover can be lifted out of the dust remover body 9.

As shown in figure 1, in the state of the fixed connection of the present invention, when the filter cloth bag 2 needs to be replaced, the lifting handle 8 is lifted to be vertical, then the lifting handle 8 is rotated to separate the present invention from the dust collector body 9, then the fixed clamping blocks 7 distributed along the left and right direction are rotated 90 degrees to make the fixed clamping blocks 7 flush with the connection holes 5 up and down, then the movable clamping ring plate 4 is separated from the bottom of the mounting ring plate 3 to make the damaged filter cloth bag 2 separated from the fixed annular clamping groove formed by the first annular groove 32 and the second annular groove 42 and pulled out from the cloth bag framework 1, then the new filter cloth bag 2 is sleeved on the cloth bag framework 1 again, the port of the new filter cloth bag 2 is clamped in the first annular groove 32, then the movable clamping ring plate 4 is attached to the bottom of the mounting ring plate 3 again, and the connection rod 6 is required to be connected to the bottom of the filter cloth bag 2 again in the attaching process, The fixed fixture block 7 penetrates through the connecting hole 5, so that the first threaded mounting flange 31 on the outer side wall of the mounting ring plate 3 and the second threaded mounting flange 41 on the outer side wall of the movable clamping ring plate 4 can form a complete threaded mounting flange, then the fixed fixture block 7 is rotated again, so that the mounting ring plate 3 and the movable clamping ring plate 4 are clamped together, and finally the invention of the filter cloth bag 2 which is replaced by a new one is screwed into the dust remover body 9 by lifting the handle 8 again.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
