Description

A filter for cement batching

Technical Field

The utility model relates to the technical field of cement filters, in particular to a filter for cement batching.

Background Art

The cement batching filter is a device used for material screening and filtering in the cement production process. It is usually used in the raw material batching system on the cement production line to screen, remove impurities and filter the raw materials. Its main function is to ensure the quality and stability of the raw materials in the cement production process. The working principle of the cement batching filter is to grade, screen and filter the raw materials through the action of the screen and filter. It can adjust the aperture and shape of the screen and filter according to different requirements and processes to achieve the required screening and filtering effect. The cement batching filter plays an important role in the cement production process. It can improve the quality and stability of raw materials, reduce the content of impurities and bad particles in production, and ensure the quality of cement products.

CN211963212U is an air sampling device for environmental detection, comprising a filter housing, a feed cylinder and a discharge cylinder respectively fixedly mounted on the top and bottom of the filter housing; a cement mixture is transported to the interior of the filter housing through the feed cylinder, and the cement mixture entering the interior of the filter housing is filtered under the action of the first filter cylinder. The cement mixture after the first filtration reaches the second filter cylinder for secondary filtration under the action of gravity, so that the cement mixture is filtered more thoroughly. When the filtration is completed, the drive motor can be started to drive the screw to rotate, and the movable plate can be moved inside the first filter cylinder under the guidance of the nut and the slide groove, so as to clean the impurities adhered to the interior of the first filter cylinder, and the cleaned impurities fall onto the movable plate, and move to the top of the feed cylinder with the movable plate, so as to facilitate the cleaning personnel to clean.

However, when the existing cement filter is in use, the material is directly poured in, and different materials are easily blocked in the feed bin when being filtered, resulting in the internal filtering speed being affected when the filtering material is added, and the filtered material is easy to remain inside the machine, making the subsequent cleaning of the machine difficult.

Therefore, we urgently need a more reliable cement batching filter.

Since the feed bin is bucket-shaped, the bottom diameter is small, so the length of stirring rod two 204 is smaller than the length of stirring rod one 203.

The vibration device includes a fixed block 403, a fixed column 404, a spring 405, a limit plate 406 and a movable block 407. A round hole is provided on the top of the fixed column 404. The upper surface of the movable block 407 is movably connected to the bottom of the filter screen. The upper surface of the limit plate 406 is fixedly connected to the bottom of the movable block 407. A groove is provided inside the fixed column 404. A spring 405 is arranged inside the groove. One end of the spring 405 is fixedly connected to the bottom of the groove, and the other end of the spring 405 is fixedly connected to the bottom of the limit plate 406. The limit plate inside the vibration mechanism squeezes the spring up and down, so that the filter screens 1 and 2 move up and down, vibrating the impurities stuck in the filter holes to prevent the accumulation of impurities.

A groove is provided inside the connecting block 2, and a driving mechanism is arranged inside the groove, which includes a connecting block 2 6, a large gear 601, a small gear 602 and a motor 603.

The large gear 601 rotates, and the connecting block 2 6 at the center of the large gear 601 drives the stirring shaft 205 to rotate, and the stirring rod 1 203 and the stirring rod 2 204 start working to stir the material to prevent large pieces of material from blocking the discharge port. After the material falls, it passes through the filter screen 401, and the filtered impurities remain on the filter screen 401, and are shaken off by the vibration mechanism at the bottom of the filter screen.

The limit plate 406 inside the vibration mechanism squeezes the spring 405 up and down, so that the filter screen 1 401 and the filter screen 2 402 move up and down, vibrating the impurities stuck in the filter holes to prevent the impurities from accumulating. The spring 405 inside the vibration device has a rebound force when it is squeezed to the limit, and the impurities on the filter screen can be shaken off by this rebound force. After two layers of filtration, the material enters the collection box 3, and the electric push rod 5 drives the cleaning plate 502 to move forward and backward, and the material in the collection box 3 is pushed out through the discharge port 301.
