Description

Technical Field

[0001] The utility model relates to the field of flushable filters, in particular to a novel flushable filter. Background Art

[0002] The filter is an indispensable device in the gas purification device, which is used to filter out dust particles in the gas;

[0003] Most existing filters cannot be washed directly with water. During use, dust and other debris that are filtered will quickly clog them. When cleaning the filters, they need to be disassembled and assembled repeatedly, which is very inconvenient to maintain. When the filters are removed and cleaned, they will cause secondary pollution to the environment and are harmful to the health of personnel.

[0004] For example, the filters of sludge low-temperature dryers and fertilizer production lines collect dust and debris mainly consisting of sludge and fertilizer particles. These materials will be removed during the filter cleaning process, which will also cause a certain amount of resource waste.

[0005] As a filter that can be automatically cleaned without disassembling the machine, the flushable filter has been widely used in various industries. Due to its characteristic of flushing from the inside, the flushable filter usually needs to have a water collection tray at the bottom to collect the wastewater after flushing (and recycle the cleaned resources at the same time). In the filtration of thermal airflow, due to the rising factor of thermal airflow, the flushable filter is usually designed to be bottom-in and top-out, but at this time the water collection tray will block part of the inlet area, affecting the filtration efficiency of the flushable filter.

[0006] To this end, the utility model proposes a novel flushable filter, which effectively reduces the impact on the filtering efficiency caused by the water collection tray blocking the air inlet without affecting the collection of the flushed sewage. Utility Model Content

[0007] The technical solution used in the utility model is: a novel flushable filter, comprising: a frame; an air outlet is opened at the upper end of the frame, and an air inlet is opened at the lower end; a filter element is fixedly installed on the frame; the air inlet and the air outlet on the frame are connected only through the filter element;

[0008] A water collecting tray is fixedly mounted on the frame, the water collecting tray is located directly below the filter element, and the vertical projection of the water collecting tray completely covers the filter element; a flushing assembly is fixedly mounted on the frame, the flushing assembly is located directly above the filter element;

[0009] The water collecting tray is provided with at least one set of closed blocking mechanisms; each set of closed blocking mechanisms comprises: a blocking plate and a push-pull unit; a plurality of blocking plates are provided, and all are rotatably connected to the water collecting tray; the push-pull unit is fixedly connected to the water collecting tray, and a rack is fixedly installed at the output end, and the rack is slidably connected to the water collecting tray; a gear is fixedly installed on each blocking plate, and each gear is meshed with the rack;

[0010] The water collecting tray is provided with a through slot which matches with each of the blocking plates and passes through from top to bottom; the blocking plates are used to block the corresponding through slots.

[0011] Furthermore, a filter screen matching each of the through slots is fixedly mounted on the water collecting tray, and each of the filter screens is located on the upper surface of the water collecting tray and covers the corresponding through slot.

[0012] Furthermore, each of the blocking plates is sheathed with a rubber ring around it.

[0013] Furthermore, an electrostatic adsorption plate is fixedly mounted on one side of each blocking plate facing the upper end of the water collecting tray.

[0014] Furthermore, each of the blocking plates is provided with a plurality of protrusions or grooves on one side facing the upper end of the water collecting tray.

[0015] Furthermore, a secondary filter component is fixedly mounted on the frame, and the secondary filter component is located above the flushing component; the secondary filter component completely covers the air outlet of the frame and is sealed and connected to the frame.

[0016] Furthermore, a purge assembly is fixedly mounted on the frame; the purge assembly is located between the filter element and the secondary filter element.

[0017] Since the utility model adopts the above technical solution, the utility model has the following beneficial effects:

[0018] 1. The utility model uses the through grooves on the water collecting tray to make the gas move upward from bottom to top, not only through the surroundings of the water collecting tray, but also through the through grooves on the water collecting tray, thereby reducing the flow resistance of the airflow; and the through grooves on the water collecting tray prevent the airflow from only moving upwards from the surroundings of the water collecting tray, resulting in inconsistent dust adhesion around the filter and the center, thereby reducing the utilization rate of the center of the filter and shortening the service life of the filter;

[0019] 2. The utility model sets a blocking plate. When flushing the filter element, the blocking plate blocks the through groove on the water collecting tray to prevent water from flowing out of the through groove and entering the air intake pipe;

[0020] 3. The utility model also filters the airflow and absorbs the dust through the filter screen and the electrostatic adsorption plate, and after the blocking plate blocks the through slot, when the flushing component sprays water, the filter screen and the blocking plate can be flushed to wash away the dust attached thereto.

[0038] The water collecting pan 4 is provided with a through slot which matches each blocking plate 41 and passes through from top to bottom; the blocking plate 41 is used to block the corresponding through slot; during use, the airflow enters from the air inlet at the lower end of the frame 1, moves upward through the surroundings of the water collecting pan, and moves upward through the through slots on the water collecting pan 4, thereby increasing the flow area of ​​the airflow and preventing the airflow from only flowing upward from the surroundings of the water collecting pan 4, causing the utilization rate of the surroundings of the filter element 2 to be much greater than that of the center, thereby affecting the service life of the filter element 2;

[0039] After a certain period of time, when the filter element 2 needs to be flushed, the four push-pull units 43 are started, and the blocking plates 41 are driven to rotate through the racks 42 and the gears on each blocking plate 41, so that the blocking plates 41 block the through grooves on the water collecting tray 4, and then the flushing assembly 3 is started to flush the filter element 2; a drain pipe is fixedly installed at the lowest point of the water collecting tray 4, and the water sprayed by the flushing assembly 3 falls into the water collecting tray 4 and is discharged through the drain pipe;

At this time, during the process of flushing the filter element 2 by the flushing component 3, when the water flows on the water collecting tray 4, the filter screen 44 and the electrostatic adsorption plate are flushed.

[0044] Specifically, each blocking plate 41 is provided with a plurality of protrusions on one side facing the upper end of the water collecting tray 4; the arrangement of the protrusions increases the contact area between the airflow and the blocking plate 41, thereby being able to absorb more dust.
