Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an integrated dry-wet positive and negative filtering dust collector with automatic cleaning function. Background Art

[0002] A dust collector is a device that separates dust from flue gas. As a commonly used equipment in the field of environmental dust removal, dust collectors are usually classified into multiple categories, including wet dust collectors, dry dust collectors, etc.

[0003] Wet dust collectors are typically equipped with a circulating water tank with automatic desilting. Water is pumped into the dust collector via a spray pump and then returned to the tank along with the dust slurry. After the dust slurry settles, it is cleared out of the tank by automatic desilting scrapers. This allows the water to be recycled, minimizing water consumption. The water level in the circulating water tank is automatically monitored and replenished with new water. Dry dust collectors, which typically use filter elements such as bag filters, cartridge filters, and sintered plates, are the most widely used type of dust collector.

[0004] The above two types of dust collectors can solve the dust removal problem to a certain extent. However, when the working environment is a place with a high oil content and sticky dust, the dust slurry and its filter element will affect the dust removal and filtration effect, resulting in unsatisfactory dust removal effect in such occasions. The specific technical solution needs further optimization and improvement. Utility Model Content

[0041] This embodiment is basically as shown in the attached Figure 1 -Attached Figure 11 As shown:

[0042] A dry-wet forward and reverse filtering integrated dust collector with automatic cleaning includes a box body 100 with an exhaust gas inlet 101 and a clean gas outlet 102, that is, the exhaust gas inlet 101 and the clean gas outlet 102 are respectively located on both sides of the box body 100.

[0043] The housing 100 is provided with a filter assembly 200, which includes a periodically operating filter screen 210. The gas to be dust-removed passes through the filter screen 210 and is discharged from the clean air outlet 102. The housing 100 also has a water tank 103 for cleaning the filter screen 210 in the filter assembly 200. The housing 100 also has a dust scraper assembly 300 for removing dust particles from the filter assembly 200. Preferably, the filter screen 210 is a high-efficiency sintered porous stainless steel mesh. Due to its inherent properties, the filter screen 210 is not easily clogged and has a long service life.

[0044] Specifically, the water tank 103 is located at the bottom of the box body 100 . During operation, cleaning water or detergent is added into the water tank 103 to clean the filter screen 210 accordingly.

[0045] To facilitate installation and operation of the filter 210, in this embodiment, a driving drum 220 and a driven shaft 230 are mounted on the housing 100. The filter 210 is arranged in a ring-shaped manner on the driving drum 220 and the driven shaft 230. Specifically, there are two driven shafts 230, which are located below the driving drum 220. The driving drum 220 and the two driven shafts 230 form a triangular arrangement. During operation, the wash water or detergent added to the water tank 103 submerges the driven shafts 230. The two sides of the filter 210 are also adapted to be inclined, and an air inlet buffer zone is formed in the upper area between the exhaust gas inlet 101 and the filter 210. Combined with the inclination of the filter 210, the filtration area is relatively increased, so that the gas to be dust-removed can be more evenly and fully in contact with the filter 210, and discharged to the outside of the box 100 through one side of the filter 210, the middle area surrounded by the filter 210, and the other side of the filter 210.

[0046] Preferably, the surface of the active roller 220 is wrapped with a soft wear-resistant silicone member, thereby increasing the friction of the active roller 220 and avoiding slipping between the filter screen 210 and the active roller 220 .

[0047] A reduction motor 110 is mounted on the outside of the housing 100, and a seated bearing 120 is mounted on the other side of the housing 100. The active roller 220 is mounted between the reduction motor 110 and the seated bearing 120, driving the active roller 220. The reduction motor 110 drives the active roller 220 in operation. Auxiliary controls can be used to adjust parameters such as the reduction motor 110's rotation time, frequency, and speed based on actual needs and the working environment, thereby adjusting the actual filtration motion. Adjustment bolts 121 and springs 122 are also mounted on both sides of the housing 100 to automatically tighten the filter screen 210.

[0048] To enhance dust removal and separate the housing 100 into an exhaust zone and a clean zone, the exhaust zone is defined as between the exhaust inlet 101 and the filter 210, while the clean zone is defined as between the clean outlet 102 and the filter 210. In this embodiment, seals 130 are installed between the edges of the housing 100 and the filter 210. A scraper 140 is fitted between the two seals 130 on the same side of the filter 210, with the bottom of the scraper 140 resting against the filter 210. Preferably, the scraper 140 is a soft rubber brush and the seal 130 is a sealing strip.

[0049] Furthermore, the seal 130 has a clamping notch 131, and the edge of the filter 210 is movably arranged at the clamping notch 131. This not only facilitates the connection stability of the filter 210, but also allows the filter 210 to move during operation, thereby simultaneously ensuring a relatively movable seal between the edge of the filter 210 and the seal 130.

[0050] The dust scraping assembly 300 includes a brush 310 and a scraper 320. The cleaning surface of the brush 310 contacts the filter 210. The scraper 320 is located below the active roller 220, and the blade of the scraper 320 abuts against the filter 210. Both ends of the scraper 320 are adapted to be mounted on the side walls of the housing 100. Preferably, the brush 310 is located on the side of the filter 210 near the clean air outlet 102. When the filter 210 is in motion, the brush 310 continuously cleans the filter 210, that is, scrapes off dust particles on the filter 210, thereby improving the cleanliness of the filter 210.

[0051] A mounting rib 150 is provided on the inner side of the box body 100 , and the seal 130 is connected to the mounting rib 150 using suitable screws or bolts, and both ends of the brush 310 are fixed to the mounting rib 150 using suitable screws or bolts.

[0052] Furthermore, the box body 100 has two partitions 160 , and the two partitions 160 are located on both sides of the active roller 220 . The scraper 140 is adapted to be installed on the corresponding partitions 160 .

[0053] After a long period of operation, some materials will stick to the surface of the active roller 220. The scraper 320 can be arranged to scrape the materials off the active roller 220, thereby improving the cleanliness of the active roller 220 and avoiding slippage between the active roller 220 and the filter screen 210.

[0054] Furthermore, a receiving trough 170 is provided on the box body 100, and the receiving trough 170 is located below the scraper 320. It is convenient to collect the material scraped from the active roller 220 and discharge it into the area surrounded by the filter screen 210 in an inclined manner, that is, fall into the water tank 103 at the bottom of the box body 100.

[0055] To facilitate drainage of the liquid in the water tank 103, in this embodiment, a drain valve 105 is installed on the housing 100 and communicates with the water tank 103. A sludge discharge slot 104 is provided on one side of the housing 100. Specifically, there are two drain valves 105, and the sludge discharge slots 104 are elongated.

[0056] The housing 100 is adapted to be mounted with multiple ultrasonic transducers 180. A heating element 190 is also provided on the housing 100 for heating the water tank 103. Preferably, the heating element 190 is a heating tube, and in this embodiment, there are two heating tubes. The multiple ultrasonic transducers 180 are located at the bottom of the housing 100. To facilitate monitoring the temperature of the water tank, a temperature sensor is also adapted to be mounted on the housing 100.

[0057] Furthermore, the box body 100 is detachably connected to an inspection door 106 and a detachably connected inspection cover 107; hollow inspection doors 106 are provided on both sides of the box body 100, and preferably, the inspection cover 107 is a transparent inspection cover 107 to facilitate observation of the working conditions inside.

[0058] The dust collector as a whole occupies a relatively small area, and the filter 210 can be cleaned in time, so that its operation is relatively stable, the filter 210 will not be blocked, and it is also relatively convenient to disassemble and install.

[0059] It should be noted that in the solution of this embodiment, other internal structures of the dust collector are existing technologies in this field, and the detailed structure and principle will not be explained here.

[0060] The specific principle and use process of this utility model are as follows:

[0061] When the system is in use, the reduction motor 110 is turned on to rotate. The reduction motor 110 drives the active roller 220 to rotate, thereby driving the filter 210 to run. The gas to be dust-removed passes through the front of the filter 210, passes through the middle area surrounded by the filter 210, and then passes through the back of the filter 210 to be filtered. That is, the gas to be dust-removed passes through two layers of filtration before being discharged. After that, the filter 210 is cleaned by the rotational motion, that is, the filter 210 contacts the cleaning water or detergent in the water tank 103 to remove dust particles and deposits them at the bottom of the box 100. The deposited sludge can be removed through the sludge discharge slot 104. According to actual needs and working environment, the liquid in the water tank can be heated by the heating element 190 to increase its activity, thereby improving the cleaning efficiency and effect of the liquid on the filter 210. The ultrasonic vibrator 180 can also be used and its vibration frequency can be adjusted according to different usage environments to improve the cleaning ability of the liquid in the water tank 103 and improve the cleaning efficiency.

[0062] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
