Water circulating type temperature-adjustable dust cap

Abstract

The invention provides a water circulating type temperature-adjustable dust cap which comprises a cap body, a semiconductor temperature adjusting module, a ventilator, a ventilation cavity, a dust filtering cover and a water circulation heat exchanger, wherein the first end face and the second end face of the semiconductor temperature adjusting module arranged on the cap body are communicated with the interior and the exterior of the cap body respectively; the ventilator is located inside the cap body; the ventilation cavity is located inside the cap body, the first end face of the semiconductor temperature adjusting module and an air inlet of the ventilator form a part of the inner wall of the ventilation cavity, and an air outlet of the ventilator forms a part of the outer wall of the ventilation cavity; the dust filtering cover is arranged on the outer wall of the cap body, and the interior of the dust filtering cover is communicated with the ventilation cavity through though holes in the cap body; the water circulation heat exchanger makes contact with the second end face of the semiconductor temperature adjusting module and conducts heat exchange. When the dust cap is used, air flow containing dust outside is filtered through the dust filtering cover, then enters the ventilation cavity, then flows through the first end face of the semiconductor temperature adjusting module to conduct heat exchange, the air flow generated after heat exchange is conducted flows through the air inlet of the ventilator and then discharged into the cap body outside the ventilation cavity through the air outlet of the ventilator. The dust cap can provide clean air, appropriate temperature and convenient communication environment for people wearing the dust cap.

Description

technical field [0001] The invention relates to the field of production of protective equipment, in particular to a temperature-adjustable dustproof cap. Background technique [0002] In material production (such as the production of cement, ceramics, building materials, refractory materials, glass, etc.), material processing (such as crushing, drilling, grinding, polishing, cutting, etc.), mining, blasting, battery production, furniture production, chemical industry , painting, sand blasting, textiles, agriculture (such as grain harvesting, grain storage, etc.), screening and mixing transportation of crushed materials, foundry industry (such as sand mixing, sand mixing, molding, and casting boxing, sand cleaning, etc.), construction Dust pollution is more serious in industries such as decoration, wall chiseling, painting, grinding, etc., railway road construction (such as tunnel digging, paving, etc.), so dust caps have become an essential production protective equipment fo...

Problems solved by technology

[0004] However, in the actual production process, although the existing dust cap can effectively protect the operator from inhaling dust and debris from the outside, because the external temperature is often high during the production process, the air in the closed dust cap The temperature will become very high. In addition, the carbon dioxide exhaled by the operator is not easy to discharge, which makes the inside of the existing dust cap extremely stuffy and the air circulation is not smooth, which seriously affects the health of the operator and production experience.

[0005] In addition, since the inside of the dust cap needs to be closed, and the working environment using the dust cap is often noisy, it is difficult for the operator wearing the dust cap to communicate with the outside world (such as calling)

This communication obstacle will also bring inconvenience to production and bring safety hazards to operators
