Description

Technical Field

[0001] The utility model relates to the field of gypsum mortar production, in particular to a dust removal device for gypsum mortar production. Background Technique

[0002] A large amount of dust will be generated during the production of gypsum mortar. At present, most of them use pulse dust collectors for dust removal. The pulse dust collector is a new type of high-efficiency pulse dust collector improved on the basis of the bag dust collector. It combines the advantages of various pulse jet dust collectors with chamber reverse blowing, overcomes the disadvantages of insufficient chamber cleaning intensity and uneven air inlet and outlet distribution, and expands the application range. When the dust-containing gas enters the dust collector from the air inlet, it first encounters the inclined plate and baffle in the middle of the air inlet and outlet, and the air flow turns and flows into the ash hopper. At the same time, the air flow speed slows down. Due to inertia, the coarse particulate dust in the gas directly flows into the ash hopper, playing a role of pre-dust collection. The air flow entering the ash hopper then turns upward and passes through the filter bag equipped with a metal skeleton inside, and the dust is trapped on the outer surface of the filter bag. The purified gas enters the clean chamber at the upper part of the filter bag chamber and is collected and discharged from the air outlet.

[0003] After retrieval, the Chinese patent publication number is CN216677475U, which discloses a dust removal device for a dry-mixed mortar production line. The patent sets a primary dust removal device for preliminary treatment of the air with dust, and sets a secondary dust removal device for secondary treatment of the air with dust. The dust removal channel is connected to the secondary dust removal device, so that the air in the dust removal channel enters the secondary dust removal device, and the filtration effect of the dust removal component is improved by setting multiple stages of dust removal.

[0004] However, the position of the filter cartridge in the above patent is fixed, resulting in uneven dust filtration on the filter cartridges close to the air inlet and far from the air inlet. When there is more dust on the filter cartridge close to the air inlet, it needs to be cleaned, and the cleaning cycle is short, affecting the filtration efficiency. Content of the Utility Model

[0024] The present utility model will be further described below with reference to the drawings:

[0025] As Figures 1-5 shown, a dust removal device for gypsum mortar production includes a dust removal cylinder 1. The inner bottom wall of the dust removal cylinder 1 is a cone with the tip facing downwards. A dust discharge port is opened on the inner bottom wall of the dust removal cylinder 1. An air inlet pipe 101 is welded to one side of the dust removal cylinder 1, and an air outlet pipe 102 is welded to one side of the dust removal cylinder 1. The air outlet pipe 102 is located above the air inlet pipe 101. A support 2 is fixedly connected to the bottom of the dust removal cylinder 1 to support the dust removal cylinder 1. A maintenance door is provided on one side of the dust removal cylinder 1.

[0026] A dust removal mechanism is arranged inside the dust removal cylinder 1. The dust removal mechanism includes a mounting plate 301 rotatably connected to the inner wall of the dust removal cylinder 1. The air inlet pipe 101 is located below the mounting plate 301, and the air outlet pipe 102 is located above the mounting plate 301. A plurality of circumferentially arranged connecting pipes 302 are rotatably connected inside the mounting plate 301. A filter bag frame is fixedly connected to the bottom of the connecting pipe 302, and a filter bag 303 is fixedly connected to the outside of the filter bag frame.

[0027] A dust discharge mechanism is arranged at the bottom of the dust removal cylinder 1. The dust discharge mechanism includes a dust discharge pipe 504 welded to the bottom of the dust removal cylinder 1. A control valve is arranged inside the dust discharge pipe 504. The dust discharge pipe 504 is communicated with the dust discharge port. A dust collection box 505 is placed on the ground below the dust removal cylinder 1. The dust discharge pipe 504 extends into the dust collection box 505. An installation groove is opened in the wall of the dust removal cylinder 1. A stepping motor 501 is bolted in the installation groove. The output end of the stepping motor 501 is connected to a rotating shaft 502 through a coupling. A plurality of paddles 503 are fixedly connected to the rotating shaft 502. The paddles 503 are located inside the dust discharge port. When discharging dust, the stepping motor 501 is started. The stepping motor 501 drives the rotating shaft 502 to drive the paddles 503 to rotate, so as to stir the dust in the dust discharge port and prevent the dust discharge port from being blocked.

[0028] A driving mechanism is arranged inside the dust removal cylinder 1. The driving mechanism includes a revolution component and a rotation component. The revolution component is used to drive the mounting plate 301 to rotate. The revolution component includes a rotary motor 304 bolted to the top of the dust removal cylinder 1. The output end of the rotary motor 304 is fixedly connected with a gear 305. The inner top wall of the dust removal cylinder 1 is rotatably connected with a toothed ring 306. The gear 305 is internally meshed with the toothed ring 306. The bottom of the toothed ring 306 is fixedly connected with a plurality of connecting rods 307. The mounting plate 301 is fixedly connected to the bottom of the connecting rods 307. When the rotary motor 304 is started, the rotary motor 304 drives the gear 305 to rotate. The gear 305 meshes with the toothed ring 306, thereby driving the toothed ring 306 to rotate. The toothed ring 306 drives the connecting rods 307 to drive the mounting plate 301 to rotate, so that the filter bag 303 revolves.

[0029] The rotation component is used to drive the connecting pipe 302 to rotate. The rotation component includes a friction ring 308 fixedly connected to the inner wall of the dust removal cylinder 1. The outer wall of the connecting pipe 302 is fixedly connected with a friction wheel 309. The friction wheel 309 abuts against the friction ring 308. When the connecting pipe 302 revolves, it will drive the friction wheel 309 to rotate. When the friction wheel 309 revolves, it drives the connecting pipe 302 to rotate under the action of the friction force provided by the friction ring 308. The connecting pipe 302 drives the filter bag 303 to rotate.

[0030] A pulse cleaning mechanism is arranged above the connecting pipe 302. The pulse cleaning mechanism includes a hydraulic cylinder 403 fixedly connected to the top of the mounting plate 301. The top of the hydraulic cylinder 403 is fixedly connected with a mounting frame 404. A cavity is formed inside the mounting frame 404. The bottom of the mounting frame 404 is fixedly connected with a plurality of pulse pipes 405. An electromagnetic pulse valve is arranged inside the pulse pipes 405. The pulse pipes 405 communicate with the cavity inside the mounting frame 404. The pulse pipes 405 are located directly above the connecting pipe 302. The top of the dust removal cylinder 1 is fixedly connected with a pulse air pump 401. The air outlet of the pulse air pump 401 is connected with a telescopic pipe 402. The telescopic pipe 402 communicates with the cavity inside the mounting frame 404. The telescopic pipe 402 is rotatably connected with the mounting frame 404. When the filter bag 303 needs to be cleaned, the mounting frame 404 is driven by controlling the hydraulic cylinder 403 to drive the pulse pipes 405 to move downward, so that the pulse pipes 405 extend into the connecting pipe 302, which is convenient for the gas ejected from the pulse pipes 405 to quickly gather inside the filter bag 303 and improve the efficiency of backwashing and cleaning.

[0031] Working principle: When in use, the gas with dust enters the dust removal cylinder 1 through the air inlet pipe 101. The dust is filtered on the filter bag 303, and the purified gas enters the cavity above the mounting plate 301 through the connecting pipe 302, and then is discharged through the air outlet pipe 102. When dust removal is carried out, the rotation motor 304 is started. The rotation motor 304 drives the gear 305 to rotate. The gear 305 meshes with the toothed ring 306, thereby driving the toothed ring 306 to rotate. The toothed ring 306 drives the connecting rod 307 to drive the mounting plate 301 to rotate, so that the filter bag 303 rotates around a circle. While the connecting pipe 302 rotates around a circle, it will drive the friction wheel 309 to rotate. During the process of the friction wheel 309 rotating around a circle, under the action of the frictional force provided by the friction ring 308, it drives the connecting pipe 302 to rotate on its own axis. The connecting pipe 302 drives the filter bag 303 to rotate on its own axis, so that the utilization rates of multiple filter bags 303 are the same, the cleaning cycle is extended, and the dust removal efficiency is improved. When it is necessary to clean the filter bag 303, the hydraulic cylinder 403 is controlled to make the mounting frame 404 drive the pulse pipe 405 to move downward, so that the pulse pipe 405 extends into the connecting pipe 302. Then, the pulse air pump 401 is started. The gas ejected by the pulse air pump 401 enters the cavity opened inside the mounting frame 404 through the telescopic pipe 402, and then is sprayed into the connecting pipe 302 through the pulse pipe 405, and then is sprayed into the filter bag 303 by the connecting pipe 302 to perform backflushing on the dust filtered outside the filter bag 303, so that the dust falls into the dust collection box 505 through the ash discharge pipe 504. When backflushing, the stepping motor 501 is started. The stepping motor 501 drives the rotating shaft 502 to drive the dial 503 to rotate, and stirs the dust in the ash discharge port to prevent the ash discharge port from being blocked.

[0032] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
