Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a clean air chamber splicing sealing structure. Background Art

[0002] The main structure of a dust collector consists of an upper clean air chamber and a lower dust chamber. As the dust-laden air flows from the dust chamber to the clean air chamber, dust particles are filtered by the filter structure, achieving the dust removal goal. Generally, the size of a dust collector increases with the processing capacity. Larger dust collectors are more difficult to transport and assemble. Therefore, the conventional practice is to design the dust collector as a separate unit, with the clean air chamber and dust chamber assembled from several structural components. Due to the high negative pressure within the clean air chamber, a high sealing requirement is required. Therefore, sealing the joints at the clean air chamber joints is a critical step in the clean air chamber assembly process. Currently, sealant is applied to the joint surfaces. After assembly, the pressure applied by bolts and other means spreads the sealant and forms a seal. This approach can affect the uniformity of the sealant application and the uniformity of the joints after compaction, resulting in residual air leakage gaps. This is especially difficult to ensure a complete seal after the sealant cures and shrinks. Therefore, it is necessary to improve the splicing sealing means. Utility Model Content

[0019] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0020] Example 1: Figure 1 and Figure 2 As shown, the clean air chamber splicing sealing structure is arranged at the joint 11 of the two splicing bodies 1 of the clean air chamber, including a sealing colloid 2 arranged in the joint 11, that is, the joint 11 of this embodiment is also applied with sealant to form a seal. Its construction is a well-known technology in the art and will not be repeated here.

[0021] The inner walls of the two joined bodies 1 are jointly provided with a sealing body 3 for sealing the inner perimeter of the joint 11. A sealing fixing structure 4 is provided between the sealing body 3 and the two joined bodies 1. The sealing body 3 forms a secondary seal at the inner perimeter of the joint 11, which, together with the sealing colloid 2, enhances the sealing effect. Furthermore, the sealing body 3 is located within the clean air chamber, minimizing the impact of the external environment and facilitating a long-term sealing effect. The terms "inner perimeter," "inner side," and "inner wall" used in this embodiment are defined as the inner space of the clean air chamber, which is the space opposite the outer space, to clearly illustrate the structural principle.

[0022] The repairing body 3 of this embodiment includes a repairing cloth 31 covering the inner periphery of the joint 11. The repairing cloth 31 can be made of a flexible material such as rubber or polyurethane, without limitation. To ensure the sealing effect of the repairing cloth 31, the repairing fixing structure 4 of this embodiment includes repairing press-fitting grooves 41 fixedly disposed on the inner walls of the two joint bodies 1. The repairing cloth 31 is bent into the two repairing press-fitting grooves 41, and each of the repairing press-fitting grooves 41 is equipped with a repairing pressure strip 42.

[0023] The repairing cloth 31 is pressed into the corresponding repairing pressing groove 41 by the repairing pressure strip 42 to fix the repairing cloth 31. The structure is simple and easy to construct. Moreover, this pressure strip pressing and fixing method is less affected by the position error of the repairing pressing groove 41, which is conducive to reducing manufacturing process requirements and reducing production costs.

[0024] The notch of the resealing and pressing groove 41 described in this embodiment faces inward. The resealing and pressing groove 41 can be formed by using C-shaped steel or sheet metal processing to form a grooved structure. The grooved structure is preferably fully welded to the inner wall of the corresponding spliced ​​body 1. Since the clean air chamber joint may be an annular seam 11, the grooved structure should also be designed in an annular shape. Preferably, the notch of the resealing and pressing groove 41 is configured to be tapered to improve the reliability of the resealing pressure strip 42 in pressing the resealing cloth 31. This tapering can be achieved by bending the groove edge at the notch of the groove structure, or by directly narrowing the resealing and pressing groove 41 from the bottom to the notch. This is not limited to this, and this embodiment only illustrates the former.

[0025] During construction, sealant is first applied to the joining surfaces of the two joined bodies 1, and the two joined bodies 1 are joined. The sealant is then spread using the force of the bolts in the joining connection, thereby forming the sealant body 2. After joining, the sealing cloth 31 is placed over the inner periphery of the joint 11, and the two sealing strips 42 are used to press-fit the two sides of the sealing cloth 31 into the corresponding sealing press-fitting grooves 41, completing the installation of the inner sealing cloth 31.

[0026] Example 2: Figure 3 As shown, this embodiment differs from the first embodiment in that the two sealing and pressing grooves 41 are arranged with their openings facing away from each other. This creates more friction between the sealing cloth 31 and the grooved structure after the sealing strips 42 compress the sealing cloth 31. This, combined with the pressure of the sealing strips 42, creates a combined force, further improving the securement of the sealing cloth 31. The sealing and pressing grooves 41 of this embodiment can also be formed by fabricating a grooved structure using C-shaped steel or sheet metal processing, or directly welded to the inner wall of the assembly 1 using angle steel. This embodiment only illustrates the latter. The narrowing of the grooves of the sealing and pressing grooves 41 is achieved in this embodiment by welding angle steel at an angle, so that the sealing and pressing grooves 41 gradually narrow from the bottom to the opening. Of course, when using C-shaped steel or other similar grooved structures, bending the groove edges can also be used. These equivalent variations are within the scope of protection.

[0027] Example 3: Figure 4 As shown, this embodiment differs from the first embodiment in that the repairing body 3 includes a repairing strip 32 disposed on the inner periphery of the joint 11. The repairing fixing structure 4 includes a repairing pressing body 43 fixedly disposed on the inner wall of one of the splicing bodies 1, and a repairing installation groove 44 opened toward the repairing pressing body 43 is fixedly disposed on the inner wall of the other splicing body 1. The repairing strip 32 is squeezed into the repairing installation groove 44 and pressed against the repairing pressing body 43.

[0028] After the said repairing seal installation groove 44 is squeezed and installed with the said repairing seal strip 32, it is pressed on the said repairing seal pressing body 43. The elastic deformation of the said repairing seal strip 32 after pressing is used to form a surface seal between it and both the repairing seal installation groove 44 and the repairing seal pressing body 43, and the two-layer sealing effect is good. The said repairing seal pressing body 43 can adopt a structure with a pressing surface of the repairing seal body 3, such as square steel, angle steel or steel plate, which is also fully welded and fixed on the inner wall of the corresponding splicing body 1. The said repairing seal installation groove 44 can be generated by a grooved structure made of C-shaped steel or sheet metal processing, and the grooved structure is also preferably fully welded and fixed on the corresponding splicing body 1. As for the splicing part of the clean air chamber, which may be an annular joint 11, the said repairing seal pressing body 43 and the grooved structure should also be set as an annular structure.

[0029] During construction, the repair strip 32 is pre-installed in the repair installation groove 44. Then, sealant is applied to the joint surface of the two splicing bodies 1. The two splicing bodies 1 are spliced ​​together, and the force of the splicing bolts causes the sealant to spread, forming the sealing body 2. The force of the splicing bolts causes the inner repair strip 32 to naturally press against the repair pressing body 43, forming a surface seal.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
