Description

Technical Field

[0001] The utility model relates to the technical field of light calcium carbonate production, in particular to a filtering device for light calcium carbonate production. Background Art

[0002] Light calcium carbonate, also known as precipitated calcium carbonate (PCC), has the chemical formula CaCO₃. It is produced using chemical processing methods. Because its sedimentation volume (2.4-2.8 mL / g) is larger than that of mechanically produced heavy calcium carbonate (1.1-1.9 mL / g), it is called light calcium carbonate. After production, light calcium carbonate undergoes dehydration, drying, pulverization, and filtration, requiring the use of filtration equipment for light calcium carbonate processing.

[0003] After searching, the utility model with Chinese patent announcement number CN207694356U discloses a stirring and filtering device for light calcium carbonate, comprising: a bracket and a tank body, the tank body is fixedly connected to the top of the bracket, a grouting port is opened on the top of the tank body, and a grouting pipe is inserted into the grouting port. This utility model allows the material to enter the filter tank through the grouting port, and then the output shaft is driven to rotate by the motor. When the output shaft rotates, the rotating column 1, the rotating column 2 and the stirring rod are driven to rotate through the connecting rod to stir the material evenly and filter it out through the filter hole. The brushes are added to the rotating column 1 and the rotating column 2 so that the material will not stick to the inner wall of the filter tank and block the filter hole, thereby greatly improving the filtering effect.

[0004] However, although the brush can clean the filter holes to a certain extent, the impurities swept away still remain in the filter tank. As the production process continues, these impurities will gradually accumulate and eventually lead to clogging of the filter holes. This clogging not only affects the filtration efficiency, but also increases the maintenance and cleaning workload of the equipment, thereby limiting production efficiency and product quality. In addition, frequent cleaning work will also increase production costs and reduce the service life of the equipment. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1-4 As shown, in this embodiment, a filtering device for producing light calcium carbonate includes:

[0023] The box body 1 is provided with a feed inlet and a discharge outlet at the top and bottom respectively;

[0024] A filter plate 2 is installed between two sides of the inner wall of the box body 1;

[0025] The mounting frame 3 is fixedly inserted into one side of the housing 1 and communicates with the housing 1. A slider 4 is slidably mounted on the housing 1. A cleaning cylinder 5 is rotatably mounted on one side of the slider 4. A cleaning brush 6 is fixedly mounted on the outer surface of the cleaning cylinder 5. A drive motor 7 for driving the cleaning cylinder 5 is fixedly mounted on the other side of the slider 4. A slide groove 11 is provided on both the housing 1 and the mounting frame 3. The slider 4 is slidably mounted between the top and bottom of the slide groove 11. Rubber strips 12 are fixedly mounted on the top and bottom of the inner wall of the slide groove 11. The diagonal portions of the slider 4 are both configured as arc surfaces.

[0026] A dust hood 8 is fixedly mounted on the cleaning cylinder 5. A dust collection assembly 9 is installed within the cleaning cylinder 5 and communicates with the dust hood 8. The dust collection assembly 9 includes a collection cylinder 91 fixedly mounted on the inner circumference of the cleaning cylinder 5. A dust pump 92 is fixedly mounted on one side of the collection cylinder 91. An L-shaped tube 93 communicates between the collection cylinder 91 and the dust hood 8. The L-shaped tube 93 prevents impurities collected in the collection cylinder 91 from rolling into the L-shaped tube 93 when the cleaning cylinder 5 is rotated, causing impurity backflow and affecting collection.

[0027] The moving component 10 is installed on the box body 1 and is used to drive the driving motor 7 to move left and right.

[0028] First, the material to be filtered enters the interior of the box body 1 through the top feed port of the box body 1. The bottom of the box body 1 is provided with a discharge port for discharging the filtered material. The filter plate 2 is installed between the two sides of the inner wall of the box body 1 to separate the materials to ensure that the materials are evenly distributed during the filtration process. The mounting frame 3 is fixed to one side of the box body 1 and is connected to the box body 1. The slider 4 is slidably installed on the box body 1 and can move along the length direction of the box body 1 in the chute 11. Rubber strips 12 are fixedly installed on the top and bottom of the inner wall of the chute 11. These rubber strips 12 can close the chute 11, but their softness does not affect the movement of the slider 4. The diagonal part of the slider 4 is designed as an arc surface, which helps the slider 4 reduce the wear on the rubber strip 12 during the sliding process.

[0029] A cleaning cylinder 5 is mounted on one side of the slider 4. A cleaning brush 6 is fixed to its outer surface and is used to clean the filter plates 2 during the filtration process to prevent material accumulation and clogging on the filter plates 2. The cleaning cylinder 5 is driven by a drive motor 7 to ensure that the cleaning brush 6 can continuously and effectively clean the filter plates 2. Slideways 11 are provided on both the housing 1 and the mounting frame 3. The slider 4 slides within these slidways, allowing the cleaning cylinder 5 to move along the length of the housing 1 for comprehensive cleaning.

[0030] Dust hood 8 is fixed to cleaning barrel 5 and communicates with dust collection assembly 9 installed within cleaning barrel 5. Dust collection assembly 9 consists of a collection barrel 91, a dust pump 92, and an L-shaped tube 93. Collection barrel 91 is fixed to the inner circumference of cleaning barrel 5, and dust pump 92 is fixed to one side of collection barrel 91. L-shaped tube 93 connects collection barrel 91 and dust hood 8. When cleaning barrel 5 is driven by drive motor 7 to rotate, thereby driving cleaning brush 6 to rotate and clean filter plate 2, dust hood 8 absorbs the cleaned impurities and collects them in collection barrel 91 via dust pump 92 for centralized processing, thereby cleaning filter plate 2 and collecting impurities.

[0031] The moving assembly 10 is mounted on the housing 1 and is used to drive the drive motor 7 and the cleaning cylinder 5 to move left and right, allowing the cleaning brush 6 to cover the entire filter plate 2, achieving all-round cleaning. Through this arrangement, the filtering device not only effectively filters the material, but also removes impurities from the filter plate 2 in real time during the filtration process, while also collecting the impurities. This prevents the cleaned impurities from accumulating on the filter plate 2, ultimately leading to poor filtration results, thereby improving filtration efficiency and the service life of the device.

[0032] like Figure 2 As shown, a lifting plate 13 is slidably inserted on the box body 1, a mounting frame 14 is fixedly installed on the top of the box body 1, an electric push rod 15 is fixedly inserted on the mounting frame 14, and the telescopic end of the electric push rod 15 is fixedly connected to the top of the lifting plate 13.

[0033] When filtering is required, the electric push rod 15 can be started to drive the lifting plate 13 to move downward, so that the chute 11 and the connecting port between the mounting frame 3 and the box body 1 can be closed to prevent the material from flowing out of the box body 1. A sealing gasket is provided on the outside of the lifting plate 13, which fits with the inner wall of the box body 1 to improve the sealing effect.

[0034] like Figure 3 As shown, a frame door 16 is provided on one side of the mounting frame 3, a closing plate 17 is inserted at one end of the collecting tube 91, and a magnet stone rod 18 is fixedly installed on one side of the closing plate 17. The closing plate 17 is precisely inserted at one end of the collecting tube 91.

[0035] After a period of cleaning and collection of impurities, the frame door 16 can be opened, and then the closing plate 17 can be pulled hard to open one end of the collecting cylinder 91, so that the impurities collected in the collecting cylinder 91 can be processed. The magnet rod 18 is used to adsorb impurities and collect iron slag when collecting impurities, so as to separate them and facilitate the subsequent processing of impurities. When the closing plate 17 is pulled again, the magnet rod 18 can be removed and the iron slag adsorbed on it can be processed at the same time.

[0036] like Figure 1As shown, the moving component 10 includes a threaded rod 101 rotatably mounted on one side of the box body 1, a moving motor 102 is fixedly mounted on one side of the mounting frame 3, the output end of the moving motor 102 is fixedly connected to one end of the threaded rod 101, and a connecting plate 103 is fixedly mounted on the bottom of the driving motor 7, which is threadedly connected to the threaded rod 101.

[0037] Starting the moving motor 102 drives the threaded rod 101 to rotate forward and reverse, thereby driving the connecting plate 103 to move left and right, and then driving the driving motor 7 to move left and right, so that the cleaning cylinder 5 connected thereto moves, thereby fully cleaning the upper surface of the filter plate 2.

[0038] The utility model provides a filtering device for the production of light calcium carbonate. The specific working principle is as follows: the material to be filtered first enters the interior of the box body 1 through the top feed port of the box body 1. After the material enters the box body 1, the filter plate 2 is installed between the two sides of the inner wall of the box body 1 to filter the material. The filtered material is discharged through the bottom discharge port of the box body 1. The filter plate 2 that has been used for a long time needs to be cleaned, and the driving motor 7 is started to drive the cleaning cylinder 5 to rotate, thereby driving the cleaning brush 6 thereon to rotate, and cleaning the impurities filtered and retained on the filter plate 2. At the same time, when the cleaning cylinder 5 rotates, the dust cover 8 will also rotate to the top of the filter plate 2, and the dust suction pump 92 is started at the same time to suck the cleaned impurities into the collection cylinder 91 through the dust cover 8, the dust cover 8 and the L-shaped tube 93. At the same time, the moving motor 102 can be started to drive the threaded rod 101 to rotate forward and reverse, thereby driving the connecting plate 103 to move left and right, and then The driving motor 7 moves left and right, so that the cleaning cylinder 5 connected thereto moves, thereby comprehensively cleaning the upper surface of the filter plate 2, preventing impurities from accumulating and clogging, and improving the filtration efficiency and service life of the equipment. After cleaning, the moving component 10 is used to drive the cleaning cylinder 5 to enter the installation frame 3 for placement, which is convenient for next use. Then the electric push rod 15 is started to drive the lifting plate 13 to move down, so that the chute 11 and the communication port between the installation frame 3 and the box body 1 can be closed to prevent materials from flowing out of the box body 1. When it is necessary to clean the impurities in the collecting cylinder 91, the frame door 16 is opened, and the closing plate 17 is pulled hard to open one end of the collecting cylinder 91, so that the impurities collected in the collecting cylinder 91 can be processed. The magnet rod 18 is used to adsorb impurities and collect iron slag when collecting impurities, so that it can be separated, which is convenient for the later impurity processing. When the closing plate 17 is pulled again, the magnet rod 18 can be moved out, and the iron slag adsorbed thereon can be processed at the same time.
