Method for cleaning inner wall of casing, material thickness detection device, cleaning equipment and concrete mixer

Abstract

The invention discloses a method for cleaning the inner wall of a machine shell. The method comprises the steps that the machine shell is provided with a device for detecting the thickness of adhered materials through ultrasonic signals; the real-time values of the thickness of the materials adhered to the inner wall of the machine shell are detected through the device; the real-time values are compared with a preset value, and a cleaning device is started up to clean the inner wall of the machine shell when the real-time values are larger than the preset value. The invention further provides a device used for detecting the thickness of concrete; the device comprises a plurality of sending probes (2), a receiving probe (3) and a host system, wherein the sending probes (2) are distributed on the outer walls of the machine shell and used for sending the ultrasonic signals, and the receiving probe (3) is arranged in a cavity of the machine shell and used for periodically receiving the ultrasonic signals. The invention further discloses cleaning equipment with the devices. The invention further discloses a concrete mixer with the cleaning equipment. In this way, the automated degree of cleaning operation of the concrete mixer can be improved, the workload of workers is reduced, and potential safety hazards are effectively eliminated.

Description

technical field [0001] The invention relates to engineering machinery, in particular to a method for cleaning the inner wall of a casing, a material thickness detection device, cleaning equipment and a concrete mixer. Background technique [0002] Concrete mixer is the key equipment for producing concrete. During the production process of the concrete mixer, it is necessary to continuously add solid materials and liquid agents to the casing. The mixture of solid material dust and liquid agent gradually adheres to the inner wall of the casing to form attachments. In addition, during the mixing process, concrete materials will also be thrown to the inner wall of the casing to form attachments. If these attachments on the inner wall of the casing are not cleaned in time, they will agglomerate about 2 hours after unloading, resulting in a reduction in the effective volume of the mixer, affecting production efficiency, and in severe cases, causing the motor to burn out.

Problems solved by technology

Although the structure of this kind of cleaning equipment is relatively simple, the start and stop time of cleaning is completely controlled by humans, resulting in greater uncertainty in the cleaning procedure.

Once the cleaning procedure is not carried out in time, it will cause the cleaning nozzle to be blocked by concrete, and it is necessary to manually clean the nozzle of the high-pressure water cleaning device

This cleanup is a lot of work and a safety hazard
