Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaning, in particular to a vacuum cleaning material separation pretreatment device. Background Art

[0002] Vacuum cleaning utilizes a high vacuum to achieve cleaning and dust removal. Unlike manual sweeping, vacuum cleaning eliminates the dust created by manual sweeping and eliminates the need for subsequent water rinsing and wastewater treatment, eliminating the risk of secondary pollution. Vacuum cleaning devices are available in two types: fixed and mobile. Mobile vacuum cleaners include vacuum cleaners and vacuum trucks. Vacuum cleaners are suitable for home use, while vacuum trucks are used in industry. Vacuum trucks are powered by an internal combustion engine mounted on a vehicle chassis, resulting in higher costs but greater flexibility. Fixed vacuum cleaning devices offer high capacity, low operating costs, and minimal maintenance.

[0003] Whether it's a mobile or fixed vacuum cleaner, a pre-treatment device is installed before the dust collector, which performs the primary dust removal function. This pre-treatment device treats incoming particles, dust, and liquids before the treated dust-laden gas enters the subsequent dust collector. Existing pre-treatment devices can only handle sweeping air streams containing either liquid or large solid particles, and are ineffective when cleaning air streams containing both large solid particles and liquid. Utility Model Content

[0004] To this end, the present invention proposes a vacuum cleaning material separation pretreatment device to improve the problems existing in the above prior art.

[0005] The technical solution of the utility model is as follows:

[0006] A vacuum cleaning material separation pretreatment device comprises an air inlet at the front, an exhaust port at the rear and a filter box in the middle, wherein the air inlet and the exhaust port are located axially of the filter box; a large particle collection hopper, a liquid collection hopper and a dust collection hopper are provided at the bottom of the filter box from front to back, a filter screen is provided at the boundary between the large particle collection hopper and the liquid collection hopper inside the filter box, a downwardly inclined liquid baffle is provided above the liquid collection hopper, a half-height first baffle is provided at the boundary between the liquid collection hopper and the dust collection hopper, the liquid baffle and the first baffle form an upward-turning air flow channel, a second baffle is provided above the dust collection hopper, the second baffle divides the space above the dust collection hopper into a filter cartridge chamber below and a clean air chamber above, and the clean air chamber is connected to the exhaust port.

[0007] As a preferred embodiment, the second baffle includes three turning sections, including a first vertical section located at the upper part, a second vertical section located at the lower part, and a horizontal section located in the middle part. The first vertical section is located above the first baffle and forms a gap between the first baffle. The horizontal section has a through hole and a filter cartridge cover concentric with the through hole is provided on its lower surface. A filter cartridge is embedded and connected to the bottom of the filter cartridge cover.

[0008] As a preferred embodiment, a plug valve is provided at the bottom end of the large particle collection hopper, a first flap valve is provided at the bottom end of the liquid collection hopper, and a second flap valve is provided at the bottom end of the dust collection hopper.

[0009] As a preferred embodiment, a filter slot is provided inside the filter box at the boundary between the large particle collection hopper and the dust collection hopper, the filter includes an outer frame and a wire mesh in the center, the outer frame cooperates with the filter slot, the shell of the filter box has a socket above the filter slot, a filter slot cover is inserted into the socket, and a handle is provided on the filter slot cover.

[0010] As a preferred embodiment, the shell of the filter box is provided with a filter cartridge replacement port on its side above the dust collection hopper, and a detachable maintenance cover is provided outside the filter cartridge replacement port, and a handle is provided on the maintenance cover.

[0011] As a preferred embodiment, sealing rings are provided between the filter cartridge cover and the filter cartridge, between the filter screen slot cover and its insertion hole, and between the filter cartridge removal port and the maintenance cover.

[0012] The working principle and beneficial effects of the utility model are as follows:

[0013] The vacuum cleaning material separation pretreatment device provided by the utility model has pipes connected to both the air inlet and the exhaust port. Airflow enters the air inlet, where large solid particles are blocked by the filter and fall into the large particle collection hopper. After removing the large solid particles, the airflow strikes a liquid baffle, where liquid droplets in the airflow converge and flow down to the liquid collection hopper. After the liquid is removed, the airflow turns upward and enters the filter cartridge chamber through a horizontal gap. After the filter cartridge filters the dust, it flows into the clean air chamber and finally flows out of the exhaust port. To replace the old filter, or to replace it with a filter of a different mesh size, the filter slot cover can be opened, the old filter can be removed, the new filter can be inserted, and the cover can be replaced to complete the filter replacement. Similarly, to replace the old filter cartridge with a new one, or to replace a filter cartridge made of a different material, the maintenance cover can be opened, the filter cartridge can be rotated and removed, the old filter cartridge can be removed, the new filter cartridge can be inserted, and the maintenance cover can be replaced. To clean the waste in the large particle collection hopper, liquid collection hopper, and dust collection hopper, the corresponding valves can be operated to complete the operation.
