Description
Technical Field
[0001] The utility model relates to the technical field of material mixing, in particular to a material mixing device with a feeding hopper. Background Art
[0002] The mixing device is a commonly used chemical production device, which can be used as a batching kettle or a reaction kettle. Figure 1A As shown, the mixing device includes a mixing container 1, an opening 2, a feeding cover 3 and an environmental protection pipe 4. The interior of the mixing container 1 contains the original material A (such as base oil), and the interior of the mixing device 1 is provided with a stirrer (omitted and not shown). The opening 2 is located at the top of the mixing container 1, and the production staff can add new materials B (such as stone powder, rubber powder, tackifier, etc.) through the opening 2. The original material A and the new material B are stirred and mixed by the stirrer and react, and the smoke / gas waste that may be generated during the reaction is discharged through the environmental protection pipe 4.
[0003] When the newly added material B contains water, after the newly added material B contacts the original material at high temperature, the water in the material B will be quickly heated and evaporated into water vapor, which will rise to the top of the mixing container together with the oil smoke and the newly added material powder, and then flow to the entrance of the environmental protection pipe in an advection manner. If it encounters an opening during the advection process, it will overflow from the opening.
[0004] like Figure 1B As shown, when the production staff opens the feeding cover 3 and feeds the material into the interior through the opening 2, a large amount of "smoke-water vapor-dust" mixture C overflows from the opening. Figure 1C As shown, even if the charging cover 3 is covered, the mixture C is easy to overflow from the gap between the charging cover 3 and the opening 2. The overflowed "smoke-water vapor-dust" mixture permeates the production workshop, seriously affecting the health of workers and environmental hygiene. Utility Model Content

[0032] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0033] The mixing device 01 with a feeding hopper in the embodiment of the utility model is as follows Figure 2 As shown, it includes a mixing container 10, an opening 20, a feeding cover 30, an environmental protection pipeline 40 and a feeding hopper 50. The pipe wall of the environmental protection pipeline 40 is arranged above the mixing container 10, and the entrance of the environmental protection pipeline 40 is arranged at the top of the mixing container 10; the opening 20 is arranged at the top of the mixing container 10. The feeding hopper 50 can be arranged at the opening 20 in a coverable manner, and when the feeding hopper 50 covers the opening 20, the lower opening of the feeding hopper 50 is lower than the top of the mixing container 10. The feeding cover 30 can be arranged above the feeding hopper 50 in a coverable manner to play a sealing role.
[0034] The mixing device 01 with a feeding hopper may also include a stirring paddle and a stirring drive device (both are omitted and not shown in the figure), wherein the stirring paddle is usually arranged inside the mixing container 10 and the stirring drive device is usually arranged outside the mixing container 10.
[0035] The working process of the mixing device with a feeding hopper in the embodiment of the utility model is as follows: Figure 2 As shown, after the newly added material B is put into the mixing container 10, it is mixed and reacted with the original material A. During the reaction, the "smoke-water vapor-dust" mixture C is discharged through the environmental protection pipe 40. Since the position of the lower opening of the feeding hopper 50 is lower than the top of the mixing container 10, it means that when the feeding hopper 50 covers the opening 20, the position of the lower opening of the feeding hopper 50 is also lower than the position of the entrance of the environmental protection pipe 40. Therefore, the "smoke-water vapor-dust" mixture C in the mixing container 10 can only rise to the top of the mixing container 10, and then can only flow horizontally to the environmental protection pipe 40 and then be discharged, thereby greatly reducing or eliminating the "smoke-water vapor-dust" mixture C from the lower opening of the feeding hopper 50 to the outside of the mixing container 10, thereby improving the sanitation of the working environment and protecting the health of workers.
[0036] In order to facilitate feeding, the upper opening area of the feeding hopper 50 can be set to be larger than the lower opening area of the feeding hopper 50, so that the newly added material B can be gathered and fall into the center of the mixing container 10, so that the stirring blades can stir the various materials more quickly and evenly. Figure 3 As shown, the feeding hopper 50 includes four side walls S1 to S4, three of which are perpendicular to the horizontal plane, and the other side wall S4 is oblique to the horizontal plane.
[0037] To enable those skilled in the art to better understand, FIG. 4A to FIG. 7 The structural details of the feeding hopper in the mixing device according to the embodiment of the utility model are shown.
[0038] like FIG. 4A to FIG. 4D As shown, the hopper 50 may include an upper hopper portion 501 and a lower hopper portion 502. FIG. 4A to FIG. 4D and Figure 5 As shown, the upper opening of the upper part 501 of the feeding hopper is a feeding inlet 5011, and the lower end of the upper part 501 of the feeding hopper is provided with an upper flange 5012. FIG. 4A to FIG. 4D and Figure 6 As shown, a lower flange 5021 is provided at the upper end of the lower part 502 of the hopper, and the lower opening of the lower part 502 of the hopper is a feeding outlet 5022. The lower flange 5021 and the upper flange 5012 are of the same shape, and the two are used to cooperate with each other for flange connection, and the flange connection has the advantages of mature technology and good fastness. The vertical projection of the upper flange 5012 and the lower flange 5021 can be set to cover the opening 20. Under this design, after the upper flange 5012 and the lower flange 5021 are connected to form a flange combination, the upper part 501 of the hopper and the lower part 502 of the hopper are connected to form an integral hopper 50, and then the flange combination is directly placed on the opening 20 of the top plane of the mixing container 10 to realize that the hopper 50 covers the opening 20, which has the advantages of convenient installation.
[0039] In order to reduce the scattering of the newly added material B during feeding, the vertical projection of the feeding inlet 5011 can be set to cover the vertical projections of the upper flange 5012 and the lower flange 5021. In this way, the probability of the newly added material B falling into the difficult-to-clean locations such as the gaps of the flange fasteners is reduced, reducing the difficulty of maintenance and cleaning.
[0040] In order to facilitate the destruction of the packaging bag of the newly added material when feeding, the feeding hopper 50 may also include at least one bag breaking component located inside the feeding hopper 50. FIG. 4A to FIG. 4D and Figure 7 As shown, the bag breaking component may specifically be a conical cross knife 503 .
[0041] In order to prevent the bag breaking component and the packaging bag from falling into the mixing container 10, the feeding hopper 50 may further include: an anti-falling component arranged below the bag breaking component. FIG. 4A to FIG. 4D and Figure 7 As shown, the anti-falling component can specifically be a flat anti-falling grille 504.
[0042] The bag breaking component and the anti-falling component can be fixedly connected (such as welding) or non-fixedly connected (such as snap-on connection), and their specific forms can also be flexibly designed, and technicians in this field can choose according to the installation site conditions.
[0043] like FIG. 4A to FIG. 4D and Figure 6As shown, a plurality of lugs 5023 may be further provided on the inner side of the upper opening of the lower part 502 of the hopper. The plurality of lugs 5023 are used to support the anti-falling grid 504 on the one hand, and are convenient for users to grasp and lift the lower part 502 of the hopper on the other hand.
[0044] The specific use process of the mixing device with a feeding hopper in this embodiment can be referred to FIG. 8A to FIG. 8F .
[0045] Fig. 8A As shown, in the initial state, the top of the mixing container 10 has an extended environmental protection pipe 40, and the opening 20 at the top of the mixing container 10 is open.
[0046] like Figure 8B As shown, the lower part 502 of the feeding hopper is first installed at the position of the opening 20, and the feeding outlet 5022 is located below the entrance of the environmental protection pipeline 40; then the upper part 501 of the feeding hopper is installed on the lower part 502 of the feeding hopper.
[0047] like Figure 8C As shown, the anti-falling grid 504 is erected on a plurality of lugs 5023 of the lower portion 502 of the feeding hopper, and then the conical cross blade 503 is placed on the anti-falling grid 504 .
[0048] After the above assembly is completed, the feeding work begins, and the newly added material bag is placed on the cone cross knife 503. After the newly added material bag is pierced by the cone cross knife 503, the newly added material flows out and falls into the mixing container 10, and the work is repeated until the feeding is completed. At this time, the working state of the mixing device is as follows: Fig.8D As shown, the mixture C does not overflow from the opening 20 .
[0049] After the feeding is completed, the mixed material usually needs to continue to react. At this time, the combination of the cone cross knife 503 and the anti-falling grid 504 can be disassembled first, and then the upper part of the feeding hopper 501 is disassembled, and finally the feeding cover 30 is covered. At this time, the device is as follows Fig. 8E shown.
[0050] Finally, the working state of the mixing device is as follows Figure 8F As shown, the mixture C will not overflow from the gap between the feeding cover 30 and the opening 20 .
[0051] The above specific implementations do not constitute a limitation on the protection scope of the present utility model. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
