Bottom charging vacuum cleaning machine

Abstract

The invention relates to a bottom charging vacuum cleaning machine comprising a machine body, a lifting and charging mechanism, a cleaning chamber, an alkaline liquid storage tank, a clear water storage tank, a vacuum pump assembly and a spraying assembly. The bottom charging vacuum cleaning machine is characterized in that the whole cleaning chamber is of a cylindrical structure, and the top and a sealing door of a sealing bottom are shaped like semicircular convex surfaces; the spraying assembly is arranged inside the cleaning chamber and is composed of a water inlet pipeline, shunting pipelines and nozzles, wherein the water inlet pipeline passes through the top of the cleaning chamber, one end of the water inlet pipeline is connected with two paths of external pipelines through rotating heads, the other end of the water inlet pipeline extends into the cleaning chamber and is connected with the two right-angled shunting pipelines through shunting accessories, the two right-angled shunting pipelines and a single flow channel arranged on the sealing bottom are uniformly provided with the plurality of nozzles, and thus, a square spraying structure is formed together; and the tail end of a drain pipe is connected with a recovery tank, the bottom of the recovery tank is connected with a water drain valve, and the tail end of an exhaust pipe is connected with the vacuum pump assembly. The bottom charging vacuum cleaning machine has the characteristics of no deformation, high sealing performance, liquid discharging thoroughness, oil-water separation, residue blockage avoidance, switching convenience and the like.

Description

technical field [0001] The invention relates to a vacuum cleaning machine, in particular to a bottom-loading vacuum cleaning machine. It belongs to the technical field of workpiece cleaning equipment. Background technique [0002] refer to Figure 11 , Figure 12 , the prior art vacuum cleaner for workpiece cleaning has the following disadvantages: [0003] (1) Due to the corner position of the cleaning chamber, the overall structure has different resistance to pressure, and it is easy to deform under the condition of uneven pressure. The sealing surface of the cleaning chamber is also square, and the radius from the center to the four axes is different, and the force is uneven, and the sealing surface is prone to water and air leakage due to deformation. The cleaning chamber needs to provide a larger volume to accommodate workpieces of the same volume, which is not conducive to water injection or rapid vacuuming. [0004] (2) When the workpiece is sent from the bottom t...
