For the oil pollution in water bodies caused by oil leakage accidents, the current treatment methods include: combustion, chemical degradation, physical filtration, adsorption materials, etc. Among them, the use of meltblown oil absorption materials has become a treatment method that has received more and more attention.

[0003] The preparation of meltblown oil-absorbing materials requires the use of three-dimensional porous non-woven materials, which use high-speed hot air flow to stretch the polymer melt stream extruded from the die spinneret hole, thereby forming ultrafine fibers and collecting them on a condensation curtain or roller, while bonding themselves to become meltblown non-woven materials.

[0004] When the raw materials are made into a polymer melt, in order to improve the melting efficiency of the raw materials, the raw materials are preheated before being added. However, in actual use, due to the large amount of raw materials inside the device, the raw materials inside the device are not heated enough, resulting in uneven heating of the raw materials during preheating, thereby affecting the preheating effect. For this reason, the utility model proposes a raw material adding device for preparing meltblown oil absorbing material to solve the above problem. Utility Model Content

[0027] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For example, see Figure 1 - Figure 7 The utility model provides a technical solution: a raw material adding device for preparing melt-blown oil-absorbing material, comprising:

[0029] A main body 1 includes an annular inner cavity 2 opened inside the side wall of the main body 1, a heating component 4 is arranged inside the annular inner cavity 2, the heating component 4 is electrically connected to an external power supply, and the heating component 4 will release a large amount of heat (such as a heating wire) inside the annular inner cavity 2 after being energized, a fixing plate 8 is fixedly connected to the outer wall of the main body 1, an air pump 9 is fixedly installed on the top of the fixing plate 8, the air pump 9 is connected to the annular inner cavity 2 through a connecting pipe, and when the air pump 9 is working, air is introduced into the annular inner cavity 2 through the connecting pipe, thereby forming a hot air flow inside the annular inner cavity 2.

[0030] An annular plate 5 is arranged inside the main body 1, and a cavity 6 is opened inside the annular plate 5. A plurality of heat-conducting pipes 7 connected with the cavity 6 are fixedly connected to the top of the annular plate 5. One end of the heat-conducting pipe 7 away from the annular plate 5 is fixedly connected to the top edge of the inner wall of the main body 1, and one end of the heat-conducting pipe 7 extends to the inside of the annular inner cavity 2 and is connected thereto, so that the hot air flow inside the annular inner cavity 2 can flow to the inside of the cavity 6 through the heat-conducting pipe 7, and at the same time, the heat in the hot air flow is conducted to the raw materials inside the main body 1 through the plurality of heat-conducting pipes 7, so that the raw materials inside the main body 1 are heated more evenly, solving the problem of insufficient heating of the inner raw materials due to excessive raw materials.

[0031] The bottom of the annular plate 5 is provided with a plurality of circular grooves 51 distributed in a circumferential array, and a blocking block 52 adapted thereto is arranged in the circular groove 51. The bottom diameter of the blocking block 52 is the same as or similar to the diameter of the circular groove 51, so that the blocking block 52 can close the notch of the circular groove 51 when it is not displaced, thereby preventing the raw material from entering the circular groove 51. The blocking block 52 is arranged in a truncated cone shape, and a spring 53 is fixedly connected to the top of the blocking block 52, and the top of the spring 53 is fixedly connected to the top of the circular groove 51. The blocking block 52 is elastically connected to the inside of the circular groove 51 through the spring 53, so that the blocking block 52 can be in the circular groove 51. The circular groove 51 moves vertically, and a plurality of through holes 54 connected with the cavity 6 are opened on the top of the circular groove 51. The hot air flow circulating in the cavity 6 enters into the circular groove 51 through the through holes 54. The circulating hot air flow forms a thrust on the elastically connected blocking block 52, thereby prompting the blocking block 52 to move downward. By setting the blocking block 52 to a table shape, the hot air flow can flow from the gap between the blocking block 52 and the circular groove 51 to the surface of the raw material in the main body when the blocking block 52 moves downward. At the same time, the thrust of the hot air circulation can block the raw material that wants to enter the circular groove 51 through the gap on the outside, thereby preventing the raw material from entering the circular groove 51 and affecting the circulation of the hot air.

[0032] In the present application, in order to improve the efficiency of the preheating treatment, the heat pipe 7 is arranged in a bent shape and multiple heat pipes 7 are distributed in a circular array. The bent heat pipe 7 increases the contact area between the heat pipe 7 and the raw material inside the main body 1, thereby improving the preheating effect. The end of the heat pipe 7 connected to the main body 1 is located above the annular heat conductive plate 3. After air is introduced into the annular inner cavity 2, the hot air flow will gradually rise. In order to facilitate the circulation of the hot air flow, the heat pipe 7 is arranged at the top of the inner wall of the annular inner cavity 2 and is located above the annular heat conductive plate 3.

[0033] In the present application, in order to improve the efficiency of preheating, an annular heat conducting plate 3 is embedded in the inner wall surface of the main body 1, and the outer wall of the annular heat conducting plate 3 is located inside the annular inner cavity 2. The annular heat conducting plate 3 absorbs the heat in the annular inner cavity 2 and conducts it to the raw material inside the main body 1, thereby improving the preheating efficiency of the raw material.

[0034] In the present application, in order to make the raw materials inside the main body 1 be heated evenly, a rotating rod 10 is arranged inside the main body 1, and the annular plate 5 is sleeved on the outer side of the rotating rod 10 so that the rotating rod 10 can rotate inside the annular plate 5, and the top of the rotating rod 10 is movably connected to the top inner wall of the main body 1 through a bearing; a driving motor 11 is fixedly installed on the top of the main body 1, and the output end of the driving motor 11 is fixedly connected to the top of the rotating rod 10. After the driving motor 11 is started, it will drive the rotating rod 10 fixedly connected to it to rotate inside the main body 1, and two vertically cross-distributed fixedly connected at the bottom end of the rotating rod 10 A cross bar 12 is located below the annular plate 5. A stirring rod 13 is fixedly connected to the top of the cross bar 12 on one side away from the rotating rod 10. The stirring rod 13 is located below the heat pipe 7. The rotating rod 10 is driven to rotate inside the main body 1 by the driving motor 11, thereby driving the cross bar 12 fixedly connected to the bottom of the rotating rod 10 to rotate inside the main body 1, thereby causing the stirring rod 13 fixedly connected to the cross bar 12 to rotate, thereby stirring the raw materials inside the main body 1. The stirred raw materials are in contact with the heat pipe 7 and the annular heat conducting plate 3, so that the raw materials are further heated evenly, thereby improving the effect of the preheating treatment.

[0035] In the present application, in order to facilitate the loading and unloading of materials by the staff, a feed port 14 is opened on one side of the upper surface of the main body 1, and the staff adds the raw materials to be preheated into the inside of the main body 1 through the feed port 14. A discharge port 15 is opened at the bottom of the main body 1, and the staff discharges the preheated raw materials through the discharge port 15 or directly sends them to the production equipment; in order to make the device more stable when used, four support rods 16 distributed in a circular array are fixedly connected to the bottom of the main body 1, and the support rods 16 support the main body 1 to ensure the stability of the device.

[0036] In actual use, the steps are as follows:

[0037] 1. The staff adds the raw materials to be preheated into the main body 1 through the feed port 14.

[0038] 2. The external power supply is electrically connected to the heating component 4 to make the heating component 4 work, and the air pump 9 is started to deliver air to the inside of the annular inner cavity 2 through the connecting pipe through the air pump 9, so that the hot air flow inside the annular inner cavity 2 is delivered to the inside of the cavity 6 through the heat conducting pipe 7;

[0039] At this time, part of the heat energy in the annular inner cavity 2 is conducted to the inside of the main body 1 through the annular heat conduction plate 3, and part of the heat flows through the heat conduction pipe 7 and the inner cavity 6 through the hot air flow, and enters the inside of the main body 1 through the through hole 54 and the gap between the circular groove 51 and the blocking block 52, thereby preheating the raw materials.

[0040] 3. At the same time, the driving motor 11 is started to drive the rotating rod 10 to rotate, thereby rotating the cross bar 12 fixedly connected thereto, thereby driving the stirring rod 13 to stir the raw materials inside the main body 1.

[0041] 4. The staff discharges the preheated raw materials through the discharge port 15 or directly delivers the raw materials to the production equipment.
