Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to the drawings, fig. 1 is a schematic cross-sectional view along a transverse direction of a showerhead, and fig. 2 is a schematic cross-sectional view of another embodiment. Melt-blown non-woven fabrics processing machine with thermoelectric generation module, including nozzle assembly 1, set up connect cloth machine assembly 2 in nozzle assembly 1 below, nozzle assembly 1 is rectangular shape, and one row of orifice is being arranged to its bottom, can spout fused high molecular polymer and high temperature hot gas flow simultaneously in this orifice, and one row of polymer fiber of 1 spun of during operation nozzle assembly forms and spouts a working face.

The nozzle assembly 1 is characterized in that a thermoelectric generation module 4 is fixedly mounted on the side face of the nozzle assembly 1, the thermoelectric generation module 4 comprises a high-temperature end heat-conducting fin 41, a low-temperature end heat-conducting fin 42 and a thermoelectric generation fin 43 clamped between the high-temperature end heat-conducting fin 41 and the low-temperature end heat-conducting fin 42, a connecting plate 5 is arranged at the upper end of one of the high-temperature end heat-conducting fin 41 and the low-temperature end heat-conducting fin 42, and the connecting plate 5 is fixedly connected to the side wall of the nozzle assembly 1 through bolts. The larger the temperature difference between the high and low temperature ends of the thermoelectric generation piece 43 is, the more electric energy is output, the heat of the high temperature end is consumed to convert the electric energy into electric energy, and the purpose of cooling the high temperature end is achieved while outputting the electric energy. The high-temperature end heat-conducting fin 41 faces the spinning working face of the nozzle assembly 1, when the temperature of the spinning working face is higher than the ambient temperature, the heat near the spinning working face can be converted into electric energy, the temperature near the spinning working face below the nozzle is rapidly reduced, and the output electric energy can be used for working of electric appliances such as fans, indicator lights and motors.
As shown in fig. 1 and 2, the connecting plate 5 is a section bar with an L-shaped cross section, the upper end of the connecting plate 5 is attached to the side wall of the nozzle assembly 1, and the lower end of the connecting plate is in a folded angle shape and can be attached to the corner of the lower end of the nozzle assembly 1. As shown in fig. 1, the utility model discloses a first embodiment, a plurality of low temperature end conducting strips 42 that set up side by side of lower extreme fixedly connected with of connecting plate 5 have the clearance between the two adjacent low temperature end conducting strips 42, and the laminating of low temperature end of thermoelectric generation piece 43 is on the inside wall of low temperature end conducting strip 42, and the laminating of high temperature end conducting strip 41 is in the high temperature end of thermoelectric generation piece 43 again, also is promptly the thermoelectric generation piece 43 inner. The thermoelectric generation sheet 43, the low-temperature end heat-conducting sheet 42 and the high-temperature end heat-conducting sheet 41 can be bonded together through heat-conducting glue or connected together through fastening bolts or connected together through buckles, the area size of each group of conductor refrigeration sheets 43 and the area size of the high-temperature end heat-conducting sheet 41 are matched with that of each low-temperature end heat-conducting sheet 42, each semiconductor refrigeration unit is arranged in a row, and a certain gap is formed between two adjacent semiconductor refrigeration units, as shown in fig. 3 and 4. The gap allows air on the cold side and air on the hot side of the semiconductor refrigeration unit to flow through each other. Therefore, the air flow flowing at high speed when the nozzle assembly 1 works can be neutralized to form negative pressure on a working surface, and the polymer fibers sprayed downwards are prevented from being disturbed by the negative pressure. In addition, when the temperature difference power generation module 4 works in this embodiment, the heat at the high temperature end of the thermoelectric power generation sheet 43 inevitably transfers to the low temperature end heat conduction sheet 42 and raises the temperature thereof, the low temperature end heat conduction sheet 42 transfers the heat to the connection plate 5 connected with the low temperature end heat conduction sheet 42 into a whole, the nozzle assembly 1, the connection plate 5 and the low temperature end heat conduction sheet 42 are connected together, the heat dissipation area is enlarged, the temperature of the nozzle assembly 1 and the temperature of the low temperature end heat conduction sheet 42 can be kept constant relatively, and the working state of the thermoelectric power generation sheet 43 is stable.
As shown in fig. 2, according to another embodiment of the present invention, the connecting plate 5 is a section bar with an L-shaped cross section, the upper end of the connecting plate 5 is attached to the sidewall of the nozzle assembly 1 through the heat insulation pad 6, the lower end of the connecting plate is fixedly connected to a plurality of high temperature end heat conduction fins 41 arranged side by side, and a gap is formed between two adjacent high temperature end heat conduction fins 41. The thermoelectric generation sheet 43 and the low-temperature-end heat conduction sheet 42 are sequentially adhered and fixed to the outer side wall of the high-temperature-end heat conduction sheet 41. The thermal insulating pad 6 prevents heat from the nozzle assembly 1 from being transferred to the connecting plate 5.
As a further improvement of the present invention, the high temperature end heat conducting strip 41 and the low temperature end heat conducting strip 42 are provided with heat dissipating fins on the surface thereof away from the thermoelectric generation piece 43. The heat dissipation fins on the high-temperature-end heat conduction fin 41 are arranged on the inner side surface of the high-temperature-end heat conduction fin, and the heat dissipation fins increase the surface area of the high-temperature-end heat conduction fin 41 and are beneficial to quickly absorbing heat in air; the heat dissipation fins on the low-temperature-end heat conduction fin 42 are arranged on the outer side surface thereof, and the surface area of the low-temperature-end heat conduction fin 42 is increased, so that heat dissipation is facilitated. In order to further improve the heat dissipation effect, as shown in fig. 2 and 3, a heat dissipation fan 7 is mounted on the heat dissipation fins on the outer side surface of the low-temperature-end heat conduction fin 42, a power end of the heat dissipation fan 7 is connected to an output end of the thermoelectric generation fin 43, and the heat dissipation fan 7 is powered by the electric energy output by the thermoelectric generation fin 43.
As a further improvement of the utility model, the thermoelectric generation module 4 has two sets, and the symmetry sets up in the both sides of nozzle assembly 1. The distance from the upper end of the high-temperature end heat-conducting fin 41 to the central axis of the spraying hole of the nozzle assembly 1 is smaller than the distance from the lower end of the high-temperature end heat-conducting fin 41 to the central axis of the spraying hole of the nozzle assembly 1. Thus, the two groups of thermoelectric generation modules 4 are symmetrically and obliquely arranged on two sides of the nozzle assembly 1, and a trapezoidal channel with a small upper part and a large lower part is formed below the nozzle assembly 1. The high-temperature airflow and the polymer fiber ejected by the nozzle assembly 1 have high initial speeds and are less influenced by the disturbance of external airflow, and the amplitude of the left-right swing of the polymer fiber is small when the polymer fiber descends; however, as the height is reduced, the descending speed of the high-temperature airflow and the polymer fibers is reduced under the action of air resistance, the influence of disturbance of the external airflow is larger and larger, the amplitude of the left-right swing when the polymer fibers descend is larger and larger, and a relatively wide descending channel is required. The upper end space of the trapezoidal channel is narrow, so that the high-temperature end heat-conducting fin 41 can be close to the spinning working surface as much as possible, the heat radiation efficiency is improved, and the heat of the polymer fiber is transferred to the high-temperature end heat-conducting fin 41 as soon as possible; the lower end of the trapezoidal channel is relatively spacious, so that the polymer fiber can swing left and right when descending, and the polymer fiber can be prevented from being adhered to the high-temperature-end heat-conducting fin 41.
In operation, a row of polymer fibers is formed from the downward discharge of the nozzle assembly 1 as indicated by arrow a in fig. 2, forming a spinning face. The high-temperature air flow sprayed from the nozzle assembly 1 entrains the polymer fibers and sprays the polymer fibers onto the fabric connecting net 3, and the polymer fibers fall onto the bearing surface of the fabric connecting net 3 and are bonded together to form a non-woven fabric. As shown by the arrow C in the figure, part of the high-temperature air flow passes through the receiving surface of the cloth receiving net 3 and enters the lower part of the receiving surface, and the high-temperature air at the position can be sucked and discharged by a draught fan. Another part of the high-temperature air flow ejected from the nozzle assembly 1 is reflected by the web 3 or the nonwoven fabric and then discharged toward both the front and rear ends in accordance with the operation of the web 3, as indicated by an arrow D, E. Therefore, high-temperature airflow sprayed out of the nozzle 1 can be rapidly discharged, the high-temperature airflow is prevented from being retained on a machine table, and the cooling efficiency of the polymer fibers is further improved.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
