Description

Technical Field:

[0001] 1. This invention relates to the field of machinery manufacturing, and its invention name is a double-sweeping disk hollow direct suction dust-free cleaning vehicle, which is an invention that solves the problems of low efficiency and high pollution during the operation of existing cleaning vehicles. Technical Background:

[0002] 2. The double-sweeping disk hollow direct suction dust-free cleaning vehicle may seem to have similar functions to ordinary cleaning vehicles in terms of technology, but the technical principle of this invention is completely different from traditional technologies. When the sweeping disk of the old technology works, the sweeping disk rotates rapidly without being enclosed, and the centrifugal force and positive pressure cause dust to fly everywhere. Only a very small part enters the suction port, and most of it is lifted up, polluting the air. To solve this design problem: 1. It is necessary to solve that the sweeping disk should work in a negative pressure environment; 2. Send the swept dust and garbage into a closed dustbin under negative pressure; 3. Separate the inhaled dust and garbage, collect the dust in the dustbin bag filter, and finally send the fine dust into the spray box for water mist purification and discharge clean air. Summary of the Invention:

[0003] 3. To create a negative pressure working environment around the sweeping disk, according to this requirement, a vacuum pipe with strong suction is connected to the center of the sweeping disk and fixed on the pipe orifice. A metal shell is configured outside the sweeping disk to enclose the upper and side parts of the sweeping disk, leaving only the brush part at the bottom unenclosed. 2. For garbage and dust collection, a high-power induced draft fan sucks the garbage into the dustbin. For garbage and dust separation, the garbage is left in the dustbin, and the dust is filtered out through the isolation wire mesh at the top, leaving coarse garbage. 3. The dust is filtered through a bag filter, and a part of the coarse ash is collected in the dust collector chamber. 4. The fine dust is purified through water mist spraying, and clean air is discharged from the rear of the spray box. 5. The power supply for the induced draft fan, sweeping disk motor, and spray water pump can be driven by a 10-kilowatt three-phase generator set through a clutch installed on the transmission shaft as needed.

[0004] The invention is realized as follows:

[0005] 4. The double-sweeping disk hollow direct suction cleaning vehicle is equipped with a compliant ordinary light truck, which is a medium-sized cleaning vehicle configuration.

The drawer panel fits the designed arc of the side of the box body (see Figure (Appended Figure 4 Figure No. 38)), and the fastening lock device is shown in (Appended Figure 1Figure 8), install a layer of galvanized wire mesh 260mm below the top of the trash can (attached Figure 2 Figure 13) is used for garbage filtering. The wire mesh is made of 30 angle steel. The frame size is 995mm*2190mm. It can be divided into two pieces to make the wire mesh. The holes are about 10mm. Two 200mm diameter garbage inlets are installed at the front of the garbage collection box. The position is 50mm below the internal filter and installed sideways. See (Attachment) Figure 1 Figure 7), the diameter of the garbage transport pipe is 200mm and a downward guide plate is installed inside the inlet (see (Attachment) Figure 2 Figure 21), two openable covers are made on the top of the trash can to facilitate maintenance and cleaning.

The dimensions of the water mist spray box are as follows: length 1000mm, width 2200mm, height 1600mm (see attached Figure 5 ), 3mm stainless steel plate reinforcement is welded to the outside of the box with carbon steel angle steel, the internal spray partition guide plate spray pipe is made of stainless steel, the partition is made of 1mm stainless steel partition with 30*30 grid holes with a diameter of 5mm, and the partition is installed 300mm below the top (attached Figure 2 Figure 17) The guide pipe is basically sealed 500mm down (attached Figure 2 Figure 16), spray box air inlet guide pipe and induced draft fan outlet pipe (attached Figure 1 Figure 10) Connect the nylon pipe with a diameter of 200mm, and make a muddy water collection and drainage in the lower part of the spray box (attached Figure 5 Figure 39) The sedimentation layer, at the lowest point, is equipped with two 50 ball valves for drainage. The size of the partition is 600mm in height, 994mm in length, and 2194mm in width. It is installed 200mm from the bottom plate and is fully welded to the box body. Under the middle partition is a water storage tank for spraying water (attachedFigure 5 Figure 40), 100mm below the middle partition, install 4 rows of sediment filter devices to reuse the water source, and the spray nozzle is installed below the upper partition (see (Attachment) Figure 2 Figure 18) The nozzles are arranged in a staggered pattern with a spacing of 200mm*200mm. The nozzle connecting pipe has a total diameter of DN25 and the branch pipe of the stainless steel pipe is DN15. Two AC motor water pumps are installed.

[0008] 7. The worm wheel induced draft fan of the sweeper is installed at the front end (attached Figure 1 Figure 2), the power comes from the car engine drive shaft with a clutch (attached Figure 2 Figure 19) guide wheel and a 10 kW three-phase AC generator (attached Figure 2 The power generated by Figure 20 is used for the induced draft fan sweeping disc water pump.

The sweeping disc is divided into a fixed part and a rotating part. The outer diameter of the inner sleeve of the fixed part is 200mm (attached). Figure 3 Figure 32) Motor installation (attached) Figure 3 Figure 29) on the gearbox cover (attached Figure 3 Figure 33), the gearbox cover is welded to the inner sleeve, and two large-diameter thin bearings are installed at both ends of the outer sleeve (see Appendix Figure 3 Figure 31) with an outer diameter of 250mm and an inner diameter of 200mm, install it into the outer sleeve and install the retaining ring 2mm below the bearing to fix the bearing and slide it down. Figure 3 Figure 30) has a flange welded to the lower end (attached Figure 3 Figure 35) is connected to the sweep plate flange, and the gear box lower cover and the side shield are welded together. The gap between the lower cover and the bottom inner sleeve is 2mm (attached Figure 3 Figure 26) To avoid friction when the outer sleeve rotates, install 4 brushes on the sweeping disc (see Figure 3 Figure 37), the two top sealing covers for the sweeping disc are made of 1.5mm thin molded (attached Figure 3 Figure 27) Install the trumpet-shaped sealing ring on the side (attached Figure 3 Figure 28) is about 150mm away from the bottom of the brush, and the double sweeping disc is retracted (attached Figure 1 Figure 6) When the electric push rod is rotated and lowered, the sweeping disc forms a high negative pressure state under the suction of the induced draft fan. The garbage and dust are sucked into the pipeline from the gaps between the rotating brushes and sent into the dust collector room of the garbage bin and then into the spray box for purification into dust-free and pollution-free environmentally friendly air.
