Automatic cleaning system for central calandria and control method

Abstract

The invention belongs to the technical field of central calandrias, and discloses an automatic cleaning system for a central calandria and a control method. The automatic cleaning system for the central calandria comprises a negative pressure system which is arranged in a machine room and a plurality of diagnosis and treatment dental chairs which are arranged in a diagnosis and treatment room; andthe negative pressure system is provided with a main pipeline in a communicating mode, the diagnosis and treatment dental chairs communicate with the main pipeline through pipelines, the outer end ofthe main pipeline is provided with an auxiliary pipeline in a communicating mode, and the outer end of the auxiliary pipeline communicates with automatic pipeline cleaning equipment. According to theautomatic cleaning system for the central calandria and the control method, the automatic pipeline cleaning equipment is arranged at the tail end of the main pipeline, when the number of use points is small, the automatic pipeline cleaning equipment can increase the air volume flowing into the main pipeline from the outside, and when the number of use points is large, the air volume flowing intothe main pipeline from the outside is reduced, so that it is guaranteed that air flow exists in the pipeline all the time, the constant air pressure in the pipeline is maintained, and all the sucked dirt is conveyed into negative pressure equipment of the machine room; and the attraction force of all dental chair points is kept constant by keeping the air pressure in the pipeline constant.

Description

technical field [0001] The invention belongs to the technical field of central piping, and in particular relates to an automatic cleaning system and control method for central piping. Background technique [0002] At present, each dental chair needs to be equipped with a negative pressure system during diagnosis and treatment in a dental hospital. Considering the sanitation and noise aspects, the central exhaust pipe negative pressure system is generally used now. The central piping negative pressure system refers to the installation of negative pressure equipment in the mechanical room, the underground piping work, the design of the piping to each dental chair point, and the use of one negative pressure equipment to match the suction of multiple dental chairs. The negative pressure system of the central exhaust pipe for dentistry is roughly divided into three categories: negative pressure for diagnosis and treatment, negative pressure for oral cavity external use, and nega...

AI Technical Summary

Problems solved by technology

[0007] The meaning of solving the above problems and defects is: the dirt gradually accumulates in the pipeline and solidifies, which leads to the gradual decrease of the suction force of the negative pressure on the side of the dental chair and prevents the decline in the efficiency of diagnosis and treatment.
