Abstract

The invention relates to a self-washing dust-free material water tank device. This device is used for the sedimentation of all kinds of road sweepers and the water washing and separation of dust and airflow to achieve dust-free discharge. The device consists of an airtight box body welded by a group of sheet metal parts. The tail is provided with a garbage dump opening and is tightly sealed with an openable and closable rear cover. The two parts of the water tank realize the integration of the water tank and the need for a separate water tank, further reducing the center of gravity of the vehicle. The dustbin is equipped with a shelf, a rotatable dustbin sealing plate, and a water outlet sealing plate. During work, water is added to a certain height above the bottom of the water inlet sealing plate. Under the action of negative pressure, the air flow passes through the bottom edge of the nozzle sealing plate, washes and removes dust with water, and is drawn out of the vehicle by the dust suction fan for discharge. The device realizes dust-free discharge, avoids the secondary dust pollution caused by the limited dust suppression effect of conventional spraying, and does not need continuous water spraying by water pumps during operation.

Description

A self-cleaning dust-free material water tank device

Technical field

The invention relates to a material water tank device used for garbage settlement collection and airflow water washing and dust removal of various road sweepers. The road sweeper is a special vehicle used for sanitation sweeping and cleaning operations.

Background technique

When the road sweeper is working, the fan installation system operates to provide the vacuum negative pressure airflow required for the absorption and lifting of ground garbage. This device is located between the fan installation system and the suction nozzle device, and is used for garbage settlement collection and airflow dust removal. After the work is completed, the device is tipped over, and the garbage and sewage contained in it are poured into the specified place. The conventional method is that the negative pressure airflow carries garbage and dust into the material box device, and the airflow in the larger cavity of the material box device decelerates to make the garbage settle at the bottom of the material box. The water mist removes the dust in the airflow, and then discharges to the outside of the vehicle through the fan system. At this time, a special water tank is used to store water, and the water is supplied to the water nozzle through the water pump to continuously spray and remove dust. However, the dust removal effect of water spray is limited, which often causes secondary pollution of the air discharge. At the same time, part of the water mist enters the fan with the air flow, causing stagnant water and corrosion. Therefore, it is necessary to completely remove the dust in the airflow in the hopper to improve the performance of the road sweeper.

Contents of the invention

In order to meet the requirements of the background technology and overcome the shortcomings and deficiencies of the background technology, the present invention provides a self-cleaning dust-free material water tank device. The material tank and the water tank of the device are integrated. The inside of the device is washed with water to remove dust, so as to realize the dust-free discharge of the airflow. When working, it is only necessary to add water to the specified height once in the device, and there is no need to continuously supply water to the device.

The technical solution of the present invention is: a self-cleaning dust-free material water tank device, including a shell 1, a hinged support 2, a hinged support 2 3, a dustbin sealing plate 4, a mesh plate 5, and an outlet pipe of a dust suction nozzle 6.

Part, the front part is the air outlet channel and accommodates the dust and sewage at the same time, and the rear part is welded with a mesh plate 5 to allow the solid waste to settle in the middle of the garbage bin. Rotate around the hinged support one 2, the dustbin sealing plate 4 is fixed on the frame plate 14 through the hinged support two 3 and can rotate around the hinged support two 3, during work, the garbage can sealing plate 4 and the nozzle sealing plate 13 The self-weight is close to the frame plate 14 for separation. When the material water tank device is lifted and dumped, the garbage bin sealing plate 4 and the nozzle sealing plate 13 are rotated and separated from the frame plate 14 by gravity, which is convenient for washing and sewage outflow. The outlet pipe 6 runs through the bottom plate 10 of the water tank and the bottom plate 11 of the dustbin, and the ground garbage enters the dustbin through the outlet pipe 6 of the suction nozzle. At a certain height from the bottom of the nozzle sealing plate 13, the feature is that: after the solid waste and dust from the suction nozzle enter the dustbin through the outlet pipe 6 of the dust suction nozzle, the solid waste will settle in the middle of the dustbin under the action of the screen plate 5 Immersed in the water at the bottom of the garbage bin, the dust passes through the screen plate 5 with the airflow, and under the negative pressure of the airflow, the water level in the air outlet channel on the front side of the shelf plate 14 and the nozzle sealing plate 13 rises, and the water level in the rear garbage bin drops to a height lower than the nozzle When sealing plate 13 bottoms, the dusty airflow in the dustbin crosses the nozzle sealing plate 13 bottoms and enters the water in the air outlet channel, the dust in the airflow is washed and settled in the water, and the clean and dust-free airflow emerges from the water surface and passes through the water. The mesh of the air duct bottom plate 16 is connected to the dust suction fan at the opening of the air duct bottom plate 16 to discharge the dust-free air. After the garbage and sewage in the garbage bin are dumped, the water stored in the water tank separated by the dust bin bottom plate 11 is pumped by the water pump. Into the dustbin, after the water level is higher than the certain height of the nozzle sealing plate 13 bottoms, you can start another working stroke.

The top of the shelf board 14 is inclined at an angle to the left.

The bottom edge of the dustbin sealing plate 4 is flush with the dustbin bottom plate 11 .

The bottom edge of the nozzle sealing plate 13 is higher than the dustbin bottom plate 11 by a height.

The invention has the following beneficial effects: the self-washing dust-free material water tank device uses water washing and dedusting to remove dust in the airflow during operation, and avoids secondary pollution of airflow discharge. When the device is working, it only needs to add water to a certain height once by the water pump. , no need for water pump to continuously supply water to spray dust, and the material box and water tank are integrated structure, no need for a separate water tank to store water.
