Description

Technical Field

[0001] The utility model relates to the field of cement processing equipment, in particular to a cement processing dust removal device. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly bind materials such as sand and stone together. For a long time, it has been widely used as an important cementitious material in civil engineering, water conservancy, national defense and other projects. In the old days, cement was also called "cement".

[0003] Cement is divided into general-purpose cement and special cement according to its use and performance. General-purpose cement mainly refers to silicate cement, ordinary silicate cement, slag silicate cement, pozzolanic silicate cement, fly ash silicate cement and composite silicate cement. Special cement has special properties or uses, such as G-grade oil well cement, fast-hardening silicate cement, road silicate cement, aluminate cement, sulphoaluminate cement, etc.

[0004] When processing cement, the raw materials need to be ground, screened, and stirred, etc., which will inevitably produce a large amount of dust. In order to ensure the health of operators, dust removal work is required. When the dust removal device is in use, the outside of the filter element is contaminated with dust, which reduces the air passing efficiency, thus reducing the filtration efficiency and requiring manual disassembly and cleaning, which reduces the practicality of the dust removal device. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

When the air pump is started in use, the air pump draws out the air inside the filter element, so that a negative pressure is formed inside the filter element, so that the outside air is sucked into the filter through the suction pipe, and then filtered by the filter element, and then discharged through the quality pipe, the dust is filtered and attached to the outside of the filter element, the electric push rod is started, and the electric push rod drives the cleaning ring to move downward, scrapes off the dust attached to the outside of the filter element, and the dust falls into the collection box and is stored, thereby ensuring the filtering effect of the filter element when it is used for a long time.

[0007] Preferably, the starting mechanism includes a support plate, an impeller, a turntable, a slot body, a spring, a trigger switch and a trigger ball, the support plate is fixed at the top position of the top cover, the impeller is movably mounted on the support plate, the turntable is fixed at the center position of the impeller, the slot body is opened inside the turntable, the spring is fixed on the inner wall of the slot body, the trigger ball is fixed on the spring, and the trigger switch is embedded and fixed on the inner wall of the slot body. When in use, air is discharged through the vertical pipe, and the impact force drives the impeller to rotate, so that the turntable rotates, and the centrifugal force causes the trigger ball to stretch the spring to contact the trigger switch. At this time, the electric push rod is in a closed state. As the filter element is blocked and the air flow is not smooth, the impact force of the air discharged from the vertical pipe is reduced, the impeller speed is reduced, and the centrifugal force of the trigger ball becomes smaller, so that the spring resets and drives the trigger ball away from the trigger switch, so that the electric push rod is started, and when the air fluidity becomes stronger, the electric push rod is closed at this time, thereby achieving the effect of automatic cleaning.

[0008] Preferably, the inner side of the cleaning ring is tightly attached to the outer side wall of the filter element.

[0009] Preferably, the vertical tube extends to the outside of the top cover.

[0010] Preferably, the impeller is located above the vertical tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model is in use, the air pump is started, and the air pump draws out the air inside the filter element, so that negative pressure is formed inside the filter element, so that the outside air is sucked into the filter through the suction pipe, and then filtered by the filter element, and then discharged through the quality pipe. The dust is filtered and attached to the outside of the filter element. The electric push rod is started, and the electric push rod drives the cleaning ring to move downward, scraping off the dust attached to the outside of the filter element.

[0014] 2. When the utility model is in use, air is discharged through the vertical pipe, and the impact force drives the impeller to rotate, so that the turntable rotates, and the centrifugal force causes the trigger ball to stretch the spring to contact the trigger switch. At this time, the electric push rod is in a closed state. As the filter element is blocked, the air flow is not smooth, the impact force of the air discharged from the vertical pipe is reduced, the impeller speed is reduced, and the centrifugal force of the trigger ball becomes smaller, so that the spring resets and drives the trigger ball away from the trigger switch. In this way, the electric push rod is started. When the air fluidity becomes stronger, the electric push rod is closed, thus achieving the effect of automatic cleaning.

As the filter element 14 is blocked, the air flow is not smooth, the impact force of the air discharged from the vertical pipe 9 is reduced, the speed of the impeller 7 is reduced, and the centrifugal force of the trigger ball 12 becomes smaller, so that the spring 13 is reset and drives the trigger ball 12 away from the trigger switch 11. In this way, the electric push rod 17 is started. When the air flow becomes stronger, the electric push rod 17 is closed, so as to achieve the effect of automatic cleaning.
