Description
Technical Field
[0001] The utility model relates to the technical field of filling equipment, in particular to a positive pressure cover for filling equipment. Background Art
[0002] In the field of filling, the filling of products such as carbonated beverages and fruit granule drinks has relatively high requirements for a sterile production environment. Therefore, a relatively sealed positive pressure cover is often used to cover the filling equipment. The design of the positive pressure cover aims to keep the air pressure inside the cover higher than the external environment, thereby preventing pollutants (such as microorganisms, dust, and impurities) in the external air from entering the cover and ensuring the hygiene and safety of the products. The positive pressure cover continuously conveys filtered clean air into the cover to make the air pressure inside the cover higher than the external environment. Usually, a filter is arranged at the top of the cover to filter the air. However, when the filter is arranged at the top of the cover, the overall height of the positive pressure cover is increased, and it is easy for the positive pressure cover to be restricted by the height of the production workshop and unable to be put into use.
[0003] Therefore, it is urgent to propose a positive pressure cover for filling equipment to solve the above technical problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a positive pressure cover for filling equipment, which can reduce the overall height of the positive pressure cover.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and cannot be construed as a limitation on the present utility model.
[0036] As Figures 1 to 4 shown, the positive pressure cover for a filling device provided in this embodiment includes a cover body 1 and a filter support 2.
[0037] The cover body 1 is covered outside the filling equipment. The cover body 1 includes a top frame 11 and a side frame 12 which are connected to each other. A top plate 13 is connected to the top frame 11 and the top plate 13 covers the top frame 11. Part of the side frame 12 is connected with a side plate 14 and the side plate 14 covers part of the side frame 12. The filter bracket 2 is connected to the remaining part of the side frame 12 and is located outside the side frame 12. The filter 3 is installed on the top of the filter bracket 2. The inside of the filter bracket 2 is communicated with the inside of the cover body 1. The gas processed by the filter 3 sequentially passes through the output end of the filter 3 and the inside of the filter bracket 2 and then enters the inside of the cover body 1. The top surface of the filter 3 is lower than the top surface of the top plate 13. The top plate 13, the side plate 14 and the filter bracket 2 provide a relatively sealed environment for the inside of the cover body 1.
[0038] Among them, the bottom of the side frame 12 is connected to the ground or workbench surface where the filling equipment is arranged, which can be specifically determined according to the actual situation. The top frame 11 and the side frame 12 can be connected to each other by welding or by bolts, screws, etc., and no specific limitation is made here.
[0039] For the positive pressure cover for the filling equipment provided in this embodiment, the filter 3 is arranged on the outer side of the cover body 1 through the filter bracket 2, and the top surface of the filter 3 is lower than the top surface of the top plate 13, that is: the highest height of the positive pressure cover in this embodiment is the height of the cover body 1, avoiding the problem that the overall height increases due to the filter 3 being arranged on the top of the cover body 1, and effectively reducing the overall height of the positive pressure cover. At the same time, since the filter 3 is arranged on the outer side of the cover body 1, the installation position height of the filter 3 is also reduced, thereby reducing the operation difficulty and operation cost of maintaining or replacing the filter 3.
[0040] As Figure 1 shown, in some embodiments, the filter brackets 2 are arranged in a plurality, and the plurality of filter brackets 2 are arranged at intervals along the circumferential direction of the cover body 1. The filters 3 are arranged in one-to-one correspondence with the filter brackets 2.
[0041] Through such an arrangement, the plurality of filters 3 can convey gas into the cover body 1 at different positions of the cover body 1, which is beneficial to improving the uniformity of the gas distribution inside the cover body 1, and further keeping the air pressure inside the cover body 1 uniform and stable.
[0042] Further, as Figure 4 shown, the filter bracket 2 includes a horizontally extending section 21 and a vertically extending section 22. The filter 3 is installed on the top of the vertically extending section 22. The horizontally extending section 21 is connected to the side frame 12. The bottom wall 211 of the horizontally extending section 21 is inclined. Along the vertical direction, the end of the bottom wall 211 far from the side frame 12 is higher than the end of the bottom wall 211 close to the side frame 12. That is: from the end far from the side frame 12 to the end close to the side frame 12, the bottom wall 211 is in a downhill shape.
[0043] With such a setting, the inclined bottom wall 211 helps to guide the gas discharged from the output end of the filter 3 to flow more smoothly into the interior of the cover body 1, reducing the stagnation of the gas inside the filter bracket 2 and being beneficial to improving the air intake efficiency inside the cover body 1.
[0044] As Figure 2 and Figure 3 shown, in some embodiments, the top frame 11 includes a plurality of first sub-frames 111, and the plurality of first sub-frames 111 are spliced together to form the top frame 11. With such a setting, compared with the integral setting of the top frame 11, the splicing method of the plurality of first sub-frames 111 is more convenient for transportation and installation.
[0045] Optionally, the plurality of first sub-frames 111 are connected to each other by first fasteners. Among them, the first fasteners can be bolts, screws, etc., and no specific limitation is made here.
[0046] In this embodiment, the top frame 11 is formed by splicing 3 first sub-frames 111. In other embodiments, the number of the first sub-frames 111 can also be greater than 3, and it can be determined according to the actual situation specifically.
[0047] Furthermore, a plurality of top plates 13 are provided, and the plurality of top plates 13 are arranged in one-to-one correspondence with the plurality of first sub-frames 111, and the top plates 13 are welded to the first sub-frames 111. By setting the top plates 13 separately, it is beneficial to reduce the difficulty of welding the top plates 13, thereby improving the assembly efficiency.
[0048] As Figure 2 and Figure 3 shown, in some embodiments, the side frame 12 includes a plurality of second sub-frames 121, and the plurality of second sub-frames 121 are spliced together to form the side frame 12.
[0049] Exemplarily, the cover body 1 in this embodiment is generally a cuboid, and the side frames 12 are distributed on the four sides of the cuboid. Therefore, setting the side frame 12 to be formed by splicing a plurality of second sub-frames 121 is not only convenient for processing and manufacturing, but also more convenient for transportation and installation.
[0050] Optionally, the plurality of second sub-frames 121 are connected to each other by second fasteners. Among them, the second fasteners can be bolts, screws, etc., and no specific limitation is made here.
[0051] In this embodiment, the side frame 12 is formed by splicing 8 second sub-frames 121. In other embodiments, the number of the second sub-frames 121 can also be set to other values, and it can be determined according to the actual situation specifically.
[0052] Furthermore, a plurality of side plates 14 are provided, and the plurality of side plates 14 are arranged in one-to-one correspondence with the plurality of second sub-frames 121. The side plates 14 are welded to the second sub-frames 121. By providing the side plates 14 separately, it is beneficial to reduce the difficulty of welding the side plates 14, thereby improving the assembly efficiency.
[0053] Optionally, when the top plate 13 is welded to the first sub-frame 111 and when the side plate 14 is welded to the second sub-frame 121, intermittent welding is used, that is, welding is performed at regular intervals and the welds are not continuous. In this way, while ensuring the structural strength, heat deformation and stress concentration generated during the welding process can be reduced.
[0054] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
