[Prior art]
Conventionally, this type of cleaning apparatus has been used for cleaning objects to be cleaned such as food, plastic pellets, electrical parts, and machine parts. The basic principle of such cleaning is that pressurized gas is supplied to the gas discharge part via the gas supply path, and the gas released from the gas adheres to the object to be cleaned by stirring or vibrating the liquid or the object to be cleaned. It removes or dissolves various types of dirt. At that time, in order to efficiently stir the object to be cleaned, it is desirable that the object to be cleaned does not fall below the gas discharge part. Therefore, the cleaning tank is usually separated from a wire mesh or the like through which the object to be cleaned does not pass. It was partitioned up and down by a plate, and a gas discharge part was arranged on the lower side.

In the conventional apparatus as described above, the gas discharge part (including the gas supply path) is generally composed of a plurality of pipes, and the pipes are generally fixed so as not to be detached from the cleaning tank.
[0005]
On the other hand, in the cleaning apparatus as described above, dirt or the like from the object to be cleaned tends to adhere to the inner wall or piping of the cleaning tank by use, and this dirt sometimes detaches and reattaches to the object to be cleaned. In addition, adhesion of the above-mentioned dirt or the like may promote the propagation of microorganisms. In order to solve these problems, the conventional cleaning apparatus needs to periodically clean the inner wall of the cleaning tank.
[0006]
[Problems to be solved by the invention]
However, in the above-described conventional apparatus, when removing the separation plate and washing the washing tank or the like, a plurality of pipes constituting the gas discharge unit become an obstacle, and even if a washing brush or a washing jet water flow is used, It was difficult to perform sufficient cleaning on the inner wall of the cleaning tank located on the lower side of the pipe. In addition, the cleaning of the pipe itself that constitutes the gas discharge portion is also complicated because the surface area is large, and it is particularly difficult to clean the back side of the pipe. For this reason, in the conventional cleaning device, it is necessary to use a cleaning tool corresponding to the cleaning part for cleaning work of the device itself or to spend a lot of time for cleaning.
[0007]
Accordingly, an object of the present invention is to provide a cleaning apparatus in which the gas discharge part can be easily removed and the inner wall of the cleaning tank can be cleaned easily and in a short time.
