Abstract: A mattress centrifugal dehydration device which includes a frame body, a dehydration assembly, and a second driving structure. The dehydration assembly has a dehydration rack, a stop member, and a first driving structure. The dehydration rack is rotatably arranged on the frame body, and a loading member of a mattress is arranged on the dehydration rack, and the loading member has a loading surface. The stop member is arranged above the loading member, the stop member has a stop surface, and an accommodating space of the mattress is formed between the stop surface and the loading surface; the first driving structure is arranged on the dehydration rack and acts on the stop member to drive it to be close to or away from the loading member so as to reduce or enlarge the accommodating space.

Abstract: The present invention discloses a mattress cleaning device including a conveying assembly, a first brush roller set, a second brush roller set, and a third brush roller set. Multiple groups of the conveying assemblies are arranged horizontally at intervals to form a conveying channel, and multiple alternate spaces are formed between the multiple groups of the conveying assemblies. The first brush roller set includes at least two movable brush roller rotatably arranged in multiple alternate spaces, and the moving brush rollers can move up and down relative to the conveying assembly in a direction perpendicular to the conveying channel so as to clean the front face and the rear face, and the lower face of a mattress. The second brush roller set is rotatably arranged above the conveying assembly to clean the upper end face of the mattress.

Abstract: A catalyst for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction as well as a preparation method and use thereof are provided. The catalyst includes a zero-valent iron and phosphorus co-modified carbon material which includes a carbon material as a carrier, a zero-valent iron supported onto the carrier and serving as an active component, and a phosphate functional group formed on the surface of the carbon material. The preparation method includes: co-modifying a carbon material using a ferric salt and organic phosphorus to obtain the catalyst for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction. The present application further provides a method for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction.
