Technical Field

[0001] The utility model relates to the technical field of a texturing machine hot box, in particular to an energy-saving structure of a texturing machine hot box. Background Art

[0002] In the existing textile industry, texturing equipment (texturing machine) is one of the important components of various polyester filament production equipment. It is a kind of textile machinery that can process untwisted yarns such as polyester and nylon into elastic yarns with medium elasticity and low elasticity through false twisting. In the production process of the texturing machine, there is a step that requires heating by a hot box; during the heating process, a large amount of smoke will be generated to form waste gas. The smoke exhaust device is used to remove the waste gas in the hot box during the production process of the texturing machine, but the high-temperature waste gas will take away a lot of heat in the hot box during the exhaust process, resulting in high energy consumption. Utility Model Content

[0003] In order to solve the above technical deficiencies, the utility model provides a texturizing machine hot box energy-saving structure, which can effectively utilize the heat in the exhaust gas.

[0004] The utility model discloses an energy-saving structure of a hot box of a texturizing machine, comprising a flat hot box, wherein a plurality of parallel chambers are separated by partitions in the hot box, a heat insulation layer is arranged on the top surface of the chamber, two ends of the chamber are communicated with the outside, a hot rail is arranged in the chamber, an inwardly concave wire-passing channel is arranged on the upper end surface of the hot rail, baffles are arranged transversely at both ends of the hot box, the lower end of the baffle is flush with the upper end surface of the hot rail, the upper end of the baffle is flush with the upper end surface of the hot box, a fence is arranged on the peripheral side of the upper end surface of the hot box, a ventilation pipe is arranged at the position corresponding to each chamber in the fence, one end of the ventilation pipe passes through the fence, The other end of the ventilation pipe is connected with the corresponding chamber through a bent pipe. Ventilation holes are provided on the upper end surface of the heat box and on the end of the insulation layer away from the bent pipe corresponding to the position of each chamber. An electromagnetic heating coil is provided on the outside of the ventilation pipe, and the electromagnetic heating coil is electrically connected to a controller. A temperature sensor is provided in the bent pipe, and the temperature sensor is electrically connected to the controller. A cover plate is provided on the upper side of the enclosure, and an exhaust port is provided on the end of the cover plate away from the ventilation hole corresponding to the position of each ventilation pipe. An exhaust branch pipe is provided on the exhaust port, and the exhaust branch pipe is connected to the exhaust main pipe. An exhaust fan is provided on the exhaust main pipe.

[0005] The principle of the above technical solution is that the exhaust fan draws air, and fresh air enters the chamber of the heat box through the ventilation pipe, wherein the baffles arranged at both ends of the heat box prevent air from entering the chamber from both ends of the heat box, and the temperature sensor detects the temperature of the air entering the chamber in real time and feeds back to the controller, and the controller controls the electromagnetic heating coil to heat the ventilation pipe, thereby heating the air to a specified temperature. It should be noted here that the ventilation pipe is made of metal material, and the hot air entering the chamber heats the untwisted wire transported on the hot rail, and smoke is generated in the process of heating the untwisted wire. The high-temperature air carrying the smoke enters the enclosed space surrounded by the upper end face, the enclosure and the cover of the heat box through the ventilation hole. The high-temperature air carrying the smoke heats the ventilation pipe during the flow in the enclosed space, thereby indirectly transferring the heat to the fresh air in the ventilation pipe, thereby achieving the effect of energy saving. Finally, the air carrying the smoke enters the exhaust branch pipe, and finally converges to the exhaust main pipe. The exhaust fan is used to transport the exhaust gas carrying the smoke to the exhaust gas treatment device for environmental protection treatment.

[0006] For better heat preservation, the bottom and sides of the heat box, the outer side of the enclosure and the upper side of the cover are all provided with insulation layers.

[0007] The utility model provides an energy-saving structure of a heat box for a texturizing machine, which has the beneficial effect of effectively utilizing the heat in the exhaust gas to preheat the fresh air, and then heating the preheated fresh air to a specified temperature for heating the untwisted yarn transported on the hot rail, thereby achieving an energy-saving effect.
