TECHNICAL FIELD

[0001] The present application relates to the technical field of dust removal equipment, in particular to a V-shaped filter core and a dust removal equipment. BACKGROUND

[0002] The filter core is a key component in the dust removal equipment and is widely used in industrial production. With the increasing demand for air quality, various types of filter cores have emerged to improve filtering efficiency and reduce maintenance costs.

[0003] However, the traditional filter core is usually vertically arranged, which has the advantages of simple structure and low cost, but has many disadvantages in practical application. For example, the vertically arranged filter core has a small filtering area per unit volume, resulting in slow air passing speed and low filtering efficiency. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a V-shaped filter core to solve the problem of low filtering efficiency caused by small filtering area due to the vertical arrangement of the current filter core.

[0005] A V-shaped filter core comprises:

[0006] A support shell is hollow inside and penetrates through both ends in the width direction, and the support shell comprises a top plate and a bottom plate, wherein the length of the top plate in the width direction is greater than the length of the bottom plate in the width direction.

[0007] Two filter layer structures are arranged at one end of the support shell in the width direction, and the two filter layer structures are arranged obliquely.

[0008] Two outer frames are fixed at one end of the support shell, and the outer frames can limit the filter layer structures.

[0009] By adopting the above technical solution, the support shell is uniquely designed, and the length difference between the top plate and the bottom plate makes the overall filter core V-shaped. Compared with the vertically arranged filter core, the V-shaped structure significantly increases the side area of the filter core, providing more filtering and releasing space. In the same space, the V-shaped filter core can accommodate more filter layer structures, or the airflow can have more sufficient contact with the filter layer structure when passing through the filter core, thereby effectively improving the filtering efficiency.

[0010] In one embodiment, the support shell further comprises two oppositely arranged side plates, each of which is connected to the top plate and the bottom plate, the top plate, the bottom plate and the side plates are integrally formed, the side plates are provided with a plurality of inwardly recessed grooves, the grooves are trapezoidal and gradually increase in size from the bottom plate to the top plate.

[0011] By adopting the technical scheme, the top plate, the bottom plate and the side plate of the support shell are integrally formed, the stability and the strength of the overall structure are enhanced, the plurality of trapezoidal grooves are arranged on the side plate and sequentially increase from the bottom plate to the top plate, and the support shell is cleverly thinned at key positions.

[0012] In one of the embodiments, the side plate inner wall is provided with a step corresponding to the groove, the step is provided with abutting faces at both ends in the width direction, and both ends of the filter layer structure abut against the abutting faces and the outer frame respectively.

[0013] By adopting the technical scheme, the filter layer structure is effectively prevented from loosening and separating due to factors such as air flow impact and vibration during use, the stability and continuity of the filtering effect are ensured, and the filter layer structure is ensured to be always in a stable working position, thereby continuously and efficiently filtering pollutants in the air and providing reliable filtering protection for the dust removal equipment.

[0014] In one of the embodiments, the length of the outer frame upper end in the width direction is less than the length of the lower end in the width direction, the bottom plate is fixedly connected with the lower end by screwing, the outer shell comprises a blocking strip, the blocking strip is arranged around the inner side of the outer frame and extends inwardly, and the blocking strip and the abutting faces jointly abut against the filter layer structure corresponding thereto.

[0015] By adopting the technical scheme, the difference in the width of the upper end and the lower end of the outer frame, combined with the screwing connection between the bottom plate and the lower end of the outer frame, makes the connection between the outer frame and the support shell more stable. The blocking strip around the inner side of the outer frame and the abutting faces of the side plate jointly abut against the filter layer structure from both ends, thereby strengthening the fixing effect of the filter layer structure and preventing the filter layer from moving or loosening during filtering, and ensuring that the filter core can maintain good filtering performance under complex working conditions.

[0016] In one of the embodiments, the outer peripheral wall surface of the support shell is provided with a first clamping part, the inner peripheral wall surface of the outer frame is provided with a second clamping part, and the first clamping part and the second clamping part are fixedly connected.

[0017] By adopting the technical scheme, the first clamping part of the outer peripheral wall surface of the support shell and the second clamping part of the inner peripheral wall surface of the outer frame are matched with each other, thereby providing a convenient and firm connection mode for the support shell and the outer frame. This connection mode not only facilitates quick positioning and fixing during production and assembly, but also can withstand external forces such as air flow impact and vibration during long-term use of the filter core, thereby ensuring that the outer frame and the support shell are always tightly connected, maintaining the stability of the overall structure of the filter core, and further ensuring that the filtering effect is not affected.

[0018] In one of the embodiments, the first clamping part is a clamping block, and the clamping block is provided with a wedge surface at one end thereof facing the outer frame corresponding thereto; and the second clamping part is a clamping groove, and the clamping block is clamped and fixed with the clamping groove.

[0019] By using the above technical solution, the wedge surface design makes the clamping block more smooth when inserted into the clamping groove, and can be automatically guided and tightly clamped, thereby enhancing the reliability of the clamping. At the same time, this design also facilitates the separation of the clamping block and the clamping groove when the filter element needs to be disassembled for maintenance or replacement, and takes into account the convenience of installation and the firmness of connection.

[0021] By using the above technical solution, the top plate is provided with an air inlet, so that the airflow can be concentrated into the filter element. The filter layer structure is in a "Z" shape and is stacked in a vertical direction, which greatly increases the surface area of the filter layer and improves the contact area with the airflow, thereby improving the filtering efficiency. The filter holes on the filter layer structure are designed according to the filtering requirements, which can accurately intercept dust and impurities of different particle sizes, further optimizing the filtering effect and meeting the requirements of efficient dust removal and purification of air.

[0022] In one of the embodiments, the outer frame is provided with a plurality of positioning ear frames at the lower end thereof in the vertical direction, the positioning ear frames extend away from the support shell, each of the positioning ear frames comprises a plurality of positioning grooves recessed downward, and the positioning grooves can position and fix the V-shaped filter element.

[0023] By using the above technical solution, the staff can quickly align through the positioning grooves and the corresponding protrusions or positioning structures in the dust removal equipment, realize accurate installation of the filter element, save installation time, and improve installation efficiency. At the same time, this positioning method also enhances the stability of the filter element after installation, ensures that the filter element will not displace during the operation of the equipment, and ensures the reliability of the filtering effect.

[0025] By using the above technical solution, the support shell is filled with active carbon, HEPA, or ceramic filter materials, which gives the V-shaped filter element multiple filtering functions. The combination of multiple filter materials enables the filter element to meet different air purification requirements and improves the comprehensive performance of the dust removal equipment.

[0026] The embodiment also provides a dust removal equipment comprising a box body and the V-shaped filter element, and the V-shaped filter element is arranged in the box body.

[0027] By adopting the above technical solution, the V-shaped filter element is applied to the dust removal equipment, and the high-efficiency filtering performance of the V-shaped filter element is fully utilized. The unique structure and multiple filtering functions of the V-shaped filter element can significantly improve the removal capacity of dust, impurities, harmful gases and other pollutants in the air of the dust removal equipment, and provide a cleaner and healthier air environment for users.

[0028] In summary, the present application at least includes one beneficial effect:

[0029] 1. By the unique design of the support shell, the length difference between the top plate and the bottom plate makes the filter element overall V-shaped.

DETAILED DESCRIPTION

[0037] The following will be described in detail below in combination with the accompanying drawings. Figs. 1-4 The V-shaped filter core provided in the present application will be described in further detail.

[0038] Example 1

[0039] Please refer to Figs. 1-4 The V-shaped filter core 1 provided in the embodiment of the present application includes a support shell 11, a filter layer structure 12, and an outer frame 13.

[0040] As Figs. 1-2 shown, the support shell 11 is hollow inside and penetrates through both ends in the width direction, and the support shell 11 includes a top plate 111 and a bottom plate 112, and the length of the top plate 111 in the width direction is greater than the length of the bottom plate 112 in the width direction. Specifically, the support shell 11 is composed of the top plate 111, the bottom plate 112, and two side plates 113. The top plate 111, the bottom plate 112, and the side plates 113 are integrally injection molded, which enhances the overall strength and stability. The side plates 113 are provided with a plurality of inwardly recessed grooves 114, and the grooves 114 are all trapezoidal and gradually increase in size from the bottom plate 112 to the top plate 111. This design makes the support shell 11 thinner, which is easier to demold and reduces production costs. At the same time, the edges of the grooves 114 in the height direction are parallel to the edges of the side plates 113, so that the support shell 11 looks like a "V" shape from the side.

[0041] The outer surface of the support shell 11 can be coated with an anti-static coating. This coating can form a stable charge distribution in the air, effectively reducing the deposition of dust and other particulate matter, thereby reducing the frequency of cleaning and maintenance. At the same time, the anti-static coating also has certain antibacterial and mildew-proof functions, which helps to maintain the sanitary state of the filter core.

[0042] As Fig. 3As shown, the filter layer structure 12 is provided with two and is arranged at one end of the support shell 11 along the width direction, the support shell 11 can surround the filter layer structure 12, and the two filter layer structures 12 are also arranged obliquely; the top plate 111 is provided with an air inlet 115, air enters the inside of the filter core through the air inlet 115, and is discharged after being filtered by the filter layer structure 12. The filter layer structure 12 is arranged in a "Z" shape and stacked along the vertical direction, which increases the contact area with air. At the same time, the filter layer structure 12 is provided with filter holes, so that the filter layer structure 12 can filter dust in the air, make the filtered air flow out of the filter core, and improve the filtering efficiency. The material of the filter layer structure 12 can be a porous ceramic material. This material has high mechanical strength and chemical stability, and can work normally in high temperature and high pressure environments. The porous ceramic material also has good air permeability and moisture absorption, and is suitable for filtering operations in humid environments; the filter layer structure 12 can also use a new type of nanofiber material. This material has a higher specific surface area and stronger adsorption capacity, which can significantly improve the filtering effect without increasing the thickness of the filter layer. At the same time, the nanofiber material also has good temperature resistance and corrosion resistance, and is suitable for various harsh working environments.

[0043] The inner wall surface of the side plate 113 is protruded to form a step 116, and the two ends of the step 116 along the width direction form abutting surfaces 117. One end of the filter layer structure 12 abuts against the corresponding abutting surface 117, so that the filter layer structure 12 is inclined and there is space between the two steps 116.

[0044] In addition, the support shell 11 can also be filled with activated carbon, HEPA or ceramic and the like filtering material or a combination of one or more to enhance the filtering performance of the filter core. The filtering material is filled between the corresponding two steps 116 and the filter layer structure 12, and the amount of filtering material can be selected according to the actual situation. When the dust in the air is easy to clean, the filtering material can not be filled or partially filled in the support shell 11. At this time, the air can be directly filtered by the filter layer structure 12, or can be sequentially filtered by the filtering material and the filter layer structure 12 to achieve multi-layer filtering; when there is more dust in the air, the filtering material can completely fill the inside of the support shell 11, so that the air is first filtered in the filtering material and then filtered by the filter layer structure 12. This design not only improves the functional diversity of the filter core, but also can select appropriate filtering materials according to different application scenarios to meet diversified filtering needs.

[0045] As Fig. 4As shown, the outer frame 13 is provided with two and is fixed with the support shell 11 along the width direction of both ends, the outer frame 13 can limit the filter layer structure 12, prevent the filter layer structure 12 from leaving the support shell 11. The length of the upper end of the outer frame 13 along the width direction is less than the length of the lower end along the width direction, and the filter core as a whole is V-shaped from the side. The inner side of the outer frame 13 is also provided with a blocking strip 131, which surrounds the inner side of the outer frame 13 and extends inward, and the blocking strip 131 can abut the outer end of the filter layer structure 12 corresponding to it, thereby making the filter layer structure 12 fixed in the support shell 11.

[0046] The outer circumferential wall surface of the support shell 11 is provided with a first clamping portion 118, and the inner circumferential wall surface of the outer frame 13 is provided with a second clamping portion 132, and the first clamping portion 118 and the second clamping portion 132 cooperate to fix, which ensures the close fixing between the outer frame 13 and the support shell 11. Specifically, the first clamping portion 118 is a clamping block, and the clamping block towards one end of the corresponding outer frame 13 is a wedge surface, and the second clamping portion 132 is a clamping groove, when the two outer frames 13 respectively approach one end of the support shell 11, the outer frame 13 slides through the wedge surface of the clamping block and then makes the clamping block extend into the clamping groove, realizing the fixing of the outer frame 13 and the support shell 11. The two ends of the support shell 11 along the width direction can also be provided with a first positioning portion 119, and the side of the blocking strip 131 facing the support shell 11 is provided with a second positioning portion 133, and the first positioning portion 119 and the second positioning portion 133 cooperate to position, which ensures the accuracy of the outer frame 13 and the support shell 11 during installation. In addition, after the support shell 11 and the outer frame 13 are fixed, the edge can also be sealed by pouring glue, preventing the air entering the support shell 11 from the air inlet 115 from being unfiltered. The lower end of the outer frame 13 can also be fixed by screwing with the bottom plate 112, ensuring the firmness of the connection.

[0047] The lower end of the outer frame 13 can be provided with a plurality of positioning lugs 134, the positioning lugs 134 extend away from the support shell 11 and are arranged at intervals, and a plurality of positioning grooves 135 are provided on each positioning lug 134. These positioning grooves 135 can not only be used for preliminary positioning of the dust removal equipment, but also can facilitate subsequent fixing operation, improve installation efficiency and accuracy.

[0048] The embodiment also provides a dust removal equipment, which comprises a box body and a V-shaped filter core 1, the box body is provided with a fan and an air duct, and the V-shaped filter core 1 is arranged in the air duct. When the fan is started, the external air can enter the air inlet 115 of the filter core through the air duct, then flow out through the filter layer structure 12 on both sides after being filtered and purified inside the support shell 11, and then flow out of the box body through the air duct, realizing the filtration of the air.

[0049] The implementation principle of the embodiment is that: by integrally forming the support shell 11 into a "V" shape, the filter layer structure 12 is arranged in the support shell 11 in an inclined manner and is abutted and fixed by the outer frame 13, so that the filtering area in a unit volume is increased, and the filtering efficiency is significantly improved. The application of the filtering material in the support shell 11 and the filter layer structure 12 further improves the filtering effect of the filter element, and is suitable for various high requirement air purification environments. By additionally arranging the positioning ear frame 134 at the lower end of the outer frame 13, the quick positioning and fixing of the filter element and the dust removal equipment are realized, the installation efficiency is greatly improved, and a V-shaped filter element 1 with simple structure, convenient assembly and installation is provided.

[0050] The above are preferred embodiments of the present application, but do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
