Roller dryer with examination clearing port

Abstract

The invention relates to a dryer, in particular to a roller dryer with an examination clearing port, and the roller dryer comprises a roller (4), a tail part cover (2), a head part cover (5) and a power mechanism (13), wherein the head part cover (5) and the tail part cover (2) are arranged on two ends of the roller (4), the power mechanism (13) is connected with the roller (4) through a supporting wheel (8), a retainer ring (3) is arranged outside the roller (4), and the side surface of the head part cover (5) is provided with the examination clearing port (22). The roller dryer has the beneficial effects that (1) when the roller dryer needs to be examined, cleared and repaired in abnormal situations that materials are accumulated on a feeding end of the roller dryer or the feeding end is blocked or required to be examined, the abnormal situations can be directly processed from the clearing port, the operating environment of the operating personnel is good, and convenience, rapidness and time and labor conservation for processing the abnormal situations on the feeding end of the roller can be realized; meanwhile, the operating personnel can be prevented from entering the roller to pollute the materials; and (2) the abnormal situations on the feeding end can be examined and cleared without stopping the machine, and the production efficiency is high.

Description

technical field [0001] The invention relates to a dryer, in particular to a drum dryer with an inspection and cleaning port. The invention belongs to the technical field of drying for eliminating liquids from solid materials or articles. Background technique [0002] The tumble dryer is a widely used drying equipment. The main part of the tumble dryer is composed of a rotating cylinder that is slightly inclined to the horizontal line. Materials enter from the cylinder at the higher end, and come out from the cylinder at the lower end under the joint action of the rotating cylinder and gravity. At the same time, the hot air passes into the cylinder and contacts with the material to dry the material. [0003] Chinese Patent Publication No. CN201772706U discloses a drum dryer, including a drum, the ends of the drum are of different heights, the feed end of the drum is higher than the discharge end, and the horizontal line of the drum is a slightly inclined rotating drum; S...

Problems solved by technology

Its main disadvantage: the material is in natural contact with the hot air provided by the heat exchange tube, and the drying effect is average

[0004] In addition to the above deficiencies, the prior art tumble dryers also have the following defects: (1) During the process of drying materials, the tumble dryer encounters material accumulation at the feed end, material blockage, or needs maintenance, etc. In case of an abnormal situation, the operator who handles the abnormal situation must enter the drum from the discharge end of the drum. The length of the drum is generally as short as eight or nine meters and as long as tens of meters. The operator who handles the abnormal situation must pass through the drum. This long distance is required to reach the side of the feed end of the drum to deal with abnormal conditions at the feed end, and the position of the operator is limited when handling, and the operating environment is poor, so it brings great inconvenience to inspection, cleaning and other operations and maintenance. , and the operator entering the inside of the drum will also cause certain pollution to the material; (2) The existing structure makes the feed end of the drum blockage and other abnormal conditions, and when it needs to be inspected, cleaned and repaired, it must be carried out under shutdown. Seriously affect production efficiency, low production efficiency
