Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas dust removal, and specifically relates to a cleaning device and an industrial waste gas dust removal device. Background Art

[0002] In the existing industrial waste gas treatment process, solid impurities such as dust in the industrial waste gas are generally first filtered out, and then the harmful substances in the industrial waste gas are purified. By separate treatment, the industrial waste gas can be treated more fully. However, when removing dust from the industrial waste gas, the existing technology mostly uses bag dust collectors to remove the dust. However, when the dust and other solid impurities intercepted in the bags of the bag dust collector are large, it is necessary to stop the machine to clean the dust and other solid impurities intercepted in the bags, which is not convenient for ensuring the dust removal efficiency of the industrial waste gas. In view of this, a cleaning device that can automatically clean dust and other solid impurities is proposed to reduce the cleaning frequency and improve the dust removal efficiency of the industrial waste gas.

[0005] In order to facilitate the collection of scraped dust and other solid impurities, the lower end of the lower connecting cylinder is further connected to a water tank, and the lower end of one side of the water tank is connected to a drain pipe.

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0018] Example 1:

[0019] Reference Figure 1-Figure 3 , the cleaning device includes: a rotating rod 6; a dust removal mechanism, the dust removal mechanism includes an upper connecting tube 1, a lower connecting tube 2, a filter cloth 3 and an annular connecting shell 4, the filter cloth 3 is fixedly connected between the upper connecting tube 1 and the lower connecting tube 2, the annular connecting shell 4 is sleeved on the outside of the filter cloth 3, and is fixedly connected to the upper connecting tube 1 and the lower connecting tube 2, one side of the annular connecting shell 4 is connected to the exhaust pipe, the rotating rod 6 is rotatably connected to the cavity formed by the upper connecting tube 1, the lower connecting tube 2 and the filter cloth 3; the fan blade group 601 is fixedly connected to the upper end of the rotating rod 6; the scraper 602 is fixedly connected to the rotating rod 6 at equidistant intervals around the circumference through the fixed rod, and the scraper 602 slides against the inner wall of the filter cloth 3.

[0020] When the industrial waste gas is subjected to dust removal treatment, the upper connecting tube 1 is first sealed and connected with the external waste gas conveying pipeline. After the connection is completed, the industrial waste gas can be transported into the dust removal mechanism, and then the dust and other solid impurities in the industrial waste gas will be intercepted by the filter cloth 3 and retained in the cavity formed by the upper connecting tube 1, the lower connecting tube 2 and the filter cloth 3. The industrial waste gas after dust removal will pass through the filter cloth 3 and be discharged to the next process through the exhaust pipe of the annular connecting shell 4 for purification treatment. When the industrial waste gas is transported to the cavity formed by the upper connecting tube 1, the lower connecting tube 2 and the filter cloth 3, the fan blade group 601 will drive the rotating rod 6 to rotate under the blowing of the industrial waste gas, and then the rotating rod 6 will drive the scraper 602 to rotate through the fixed rod, and then the scraper 6 02 can scrape off the dust and other solid impurities intercepted on the filter cloth 3, so as to avoid too much dust and other solid impurities adhering to the filter cloth 3, blocking the filter holes and affecting the passage of industrial waste gas, and effectively ensuring the smooth passage of industrial waste gas through the filter cloth 3 after filtering out the dust and other solid impurities. Through the setting of the fan blade group 601, when the industrial waste gas is transported in the cavity formed by the upper connecting tube 1, the lower connecting tube 2 and the filter cloth 3, the airflow generated by the industrial waste gas can be used to drive the scraper 602 to rotate, thereby completing the cleaning of the dust and other solid impurities on the filter cloth 3 without adding an additional power source, and the speed of rotation of the scraper 602 can change with the flow rate of the industrial waste gas, effectively ensuring the cleaning effect of the dust and other solid impurities on the filter cloth 3.

[0021] Example 2:

[0022] Reference Figure 1-Figure 3, the cleaning device is basically the same as that of Example 1, and further: the lower end of the lower connecting tube 2 is connected to the water tank 5, and the lower end of one side of the water tank 5 is connected to a drain pipe. By connecting the water tank 5 at the lower end of the lower connecting tube 2, when the scraper 602 scrapes off the dust and other solid impurities on the filter cloth 3, the dust and other solid impurities will enter the water in the water tank 5 downward under the blowing of the exhaust gas, thereby adsorbing the dust and other solid impurities, and preventing the dust and other solid impurities from floating in the cavity formed by the upper connecting tube 1, the lower connecting tube 2 and the filter cloth 3 after being scraped, and then adhering to the filter cloth 3 again, further reducing the frequency of manual cleaning.

[0023] The lower end of the rotating rod 6 extends downward into the water tank 5. The rotating rod 6 is fixedly connected to a plurality of rows of stirring rods 603 at a position inside the water tank 5. When the rotating rod 6 drives the scraper 602 to scrape off the dust and other solid impurities on the filter cloth 3, it can also drive the stirring rod 603 to stir in the water, so that the dust and other solid impurities can be mixed in the water, avoiding the precipitation of dust and other solid impurities, which affects the subsequent cleaning efficiency of dust and other solid impurities.

[0024] Sockets are symmetrically provided on the upper ends of both sides of the water tank 5, and sealing plates 501 are connected to both sides of the water tank 5 through the sockets. An arc-shaped groove is provided on the sealing plate 501 near the rotating rod 6 for use with the rotating rod 6. When there is a lot of dust and other solid impurities mixed in the water, the sewage needs to be discharged and replaced with clean water. At this time, the sealing plate 501 can be pushed into the water tank 5 to isolate the lower connecting tube 2 from the water tank 5, and then the sewage in the water tank 5 can be replaced. When the water replacement operation is completed, the sealing plate 501 can be opened to connect the lower connecting tube 2 with the water tank 5 to continue to adsorb solid impurities such as dust. Through the setting of the sealing plate 501, the discharge of solid impurities such as dust can be completed without stopping the machine, which effectively ensures the dust removal efficiency of industrial waste gas.

[0025] The water tank 5 is a transparent water tank. By making the water tank 5 transparent, when solid impurities such as dust enter the water in the water tank 5, it is possible to judge whether the water needs to be replaced by observing the degree of dirtiness of the water, which provides convenience for the staff.

[0026] Example 3:

[0027] Reference Figure 1-Figure 3 The industrial waste gas dust removal device adopts a cleaning device. When the industrial waste gas is subjected to dust removal treatment, by adopting the cleaning device, when the dust and other solid impurities in the waste gas are cleaned, the continuity of the waste gas dust removal can be guaranteed, and there is no need for the staff to shut down the device to clean the filter cloth 3, which effectively improves the efficiency of the waste gas dust removal.

[0028] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
