Detailed Description
In the description of the present invention, it should be understood that the terms "left", "right", "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
In order to facilitate the technical solution disclosed in the present invention to be fully understood by those skilled in the art, the following detailed description is made in conjunction with the specific embodiments, and fig. 1 shows a schematic structural diagram of a first embodiment of the thermoplastic extrusion molding brace cooling and conveying device of the present invention, which mainly comprises a conveyor 1, a housing 2, a cold water supply device 3, and an air exhaust device 4. The conveyor 1 includes a frame 11 and an idler 12. The carrier rollers 12 are used for supporting the top bracing piece, are provided in a plurality, are fixed on the frame 11 in a linear arrangement manner, and can freely rotate around the central axis of the carrier rollers. The housing 2 is removably secured to the frame 11 and the idler 12 is disposed within its interior. The cold water supply device 3 includes a water pump 32 and an atomizing sprinkler head 33. In the process of cold treatment of the pulling strip, the atomized water spray heads 33 are continuously supplied with cooling water by the water pump 32, the number of the atomized water spray heads is multiple, the atomized water spray heads are arranged in the inner cavity of the housing 2 and are uniformly distributed right above the carrier roller 12. The air extractor 4 is communicated with the inner cavity of the housing 2. Through adopting above-mentioned technical scheme to set up, carrying out the in-process that cold treatment was carried out to the brace, air exhaust device 4 lasts work in order to form certain negative pressure at housing 2 inner chamber to in time extract the produced vapor of brace in cooling process housing 2 inner chamber and sulfuration gas, thereby avoid it to give off to workshop inside and influence the appearance of operational environment condition.
It should be noted that the left and right side walls of the housing 2 are respectively provided with an inlet and an outlet for guiding the pulling strip in and out. However, in order to obtain a good application effect, it is preferable to seal the inner cavity of the housing 2 as much as possible to better facilitate the formation of negative pressure and improve the discharge thoroughness of the vapor and the sulfide gas in the cold treatment.
It is known that, although the technical solution can effectively ensure that the environment in the workshop is free from the pollution of water vapor and sulfuration gas, the direct discharge can cause pollution and harm to the outdoor atmosphere environment (particularly sulfuration gas), for this reason, fig. 2 shows a schematic structural diagram of a second embodiment of the thermoplastic extrusion molding brace cooling and conveying device of the present invention, which is different from the first embodiment in that: a purification device 5 is additionally provided, which is arranged downstream of the suction device 4. The purging device 5 comprises a chamber 51 and a purging assembly 52. The number of the purge elements 52 is at least 2, and the purge elements are fixed in the chamber 51 and sequentially spaced along the gas flowing direction.
Generally, the cleaning assembly 52 is required to be cleaned or replaced for a certain period of time to ensure the treatment efficiency of the water vapor and the sulfuration gas, and therefore, the cleaning assembly 52 includes a cleaning body 521 and a fixing bracket 522. The fixing bracket 522 is detachably fixed in the chamber 51. The cleaning body 521 includes at least one moisture filter plate made of a desiccant and a sulfuration gas filter plate made of graphite. The moisture filter panel corresponds exactly to the air inlet of the chamber 51 (as shown in fig. 3). The purifying body 521 is supported by the fixing bracket 522, so that when the purifying effect of the purifying assembly 52 is lower than a standard value, the whole replacement is convenient.

Wherein the purifying body 521 is placed on and fixed to the annular support plate 5221. The coupling flange 5222 is formed by extending upwardly around the periphery of the annular support plate 5221. A plurality of countersunk through holes are pre-bored, evenly distributed, around the circumference of the coupling flange 5222 to facilitate coupling with the chamber 51 by means of screws (as shown in fig. 4).

The thermoplastic extrusion molding brace cooling conveying device is additionally provided with a detection device 6 and a controller 7. The detection device 6 is arranged at the gas outlet of the chamber 51 and used for detecting the content of sulfide in the mixed gas in real time, feeding back the detection data to the controller 7 in time for data processing, comparing the detection data with a preset standard value of the controller 7, and correspondingly controlling the limit number to the variable frequency motor so as to adjust the flow speed of the gas in the chamber. Therefore, the working power of the air extracting device 4 is automatically controlled and adjusted according to actual detection data, so that the processing capacity of the air extracting device is matched with the generating speed of the sulfide gas in the cold processing process, the sulfide content of the gas discharged to the atmosphere outside a workshop meets the environmental detection standard, the high-power idling time of the air extracting device 4 is effectively reduced, and the utilization rate of electric energy is improved.
Fig. 6 shows a schematic structural diagram of a fourth embodiment of the cooling and conveying device for thermoplastic extrusion molding brace of the present invention, which is different from the above three embodiments in that: a cooling device 8 is additionally provided to further increase the cooling speed and the cooling processing capacity of the brace. The air-conditioning apparatus 8 is mainly constituted by a fan assembly 81 and an air distribution plate 82. The air distribution plate 82 is in communication with a fan 81 assembly, which is disposed directly above the idler 12 to facilitate continuous cooling of the brace.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
