Description

Technical Field

[0001] The invention relates to the technical field of kaolin filter cake crushing, in particular to a kaolin cake crushing machine suitable for online flow operation. Background Art

[0002] Kaolin is a non-metallic mineral, a type of clay and claystone primarily composed of clay minerals from the kaolinite family. Kaolin possesses excellent physical and chemical properties, including plasticity and fire resistance. Consequently, kaolin has a wide range of uses, primarily in papermaking, ceramics, and refractory materials, as well as in coatings, rubber fillers, enamels, and white cement raw materials. Smaller amounts are used in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, pesticides, pharmaceuticals, textiles, petroleum, chemicals, building materials, and defense industries.

[0003] Kaolin mining is relatively common. During the mining process, the crushing of kaolin ore can be roughly divided into wet grinding and dry grinding according to the different crushing equipment. This application is related to wet grinding. After wet grinding, the kaolin ore is crushed into slurry. The slurry is dehydrated and formed into kaolin filter cake after being filtered. The kaolin filter cake requires a crushing process before it can enter the subsequent pulping tank for better sedimentation treatment. However, there is currently no crushing equipment that can be used in conjunction with the filter press in the crushing of kaolin filter cake. Moreover, the current kaolin filter cake crushing equipment has poor performance. Kaolin itself is sticky. After passing through the filter press, a certain amount of water is added, and the kaolin filter cake becomes even stickier. There is a difference between the crushing of kaolin filter cake and kaolin ore. The particle size and hardness of kaolin filter cake are smaller than those of kaolin ore, but its viscosity is significantly higher than that of kaolin ore. Moreover, its obvious viscosity will cause many crushing equipment to fail to operate normally, either by sticking to the crushing trough in large quantities or blocking the discharge port, etc.

[0004] Existing kaolin crushing, such as CN202021247829.9, patent name: Kaolin crushing production and batching system, adopts a multi-step crushing process for kaolin crushing, which is suitable for direct crushing of mined kaolin ore and is not suitable for the aforementioned filter press, that is, the crushing object is not kaolin filter cake.

[0005] For example, CN202121146769.6, the patent name: A crusher for kaolin ore, is also aimed at direct crushing of kaolin ore, which is not suitable for the aforementioned filter press, that is, the crushing object is not kaolin filter cake.

[0006] For example, CN201721739511.0, patent name: A crushing device for kaolin ore dressing with complete discharge, is also aimed at the direct crushing of kaolin ore. Although the improved design of its discharge port can solve the problem of filtering and discharging internal dust, it will eventually be blocked when used to crush the kaolin filter cake.

[0007] At present, the closest prior art in the patent system may be CN202121945233.0, a kaolin mud cake roller crushing device, but this patent also seems to ignore the hidden dangers caused by the obvious stickiness of the kaolin filter cake. It adopts the design of upper feeding and lower discharging, and uses a closed crushing trough on the crushing roller. Moreover, the design of the crushing roller makes the kaolin filter cake easier to adhere and easier to get stuck. The material scraped off from the crushing roller by the scraper plate will gradually accumulate in the space enclosed by the scraper plate, the side wall of the crushing trough and the crushing roller. If it is not cleaned in time, it will also get stuck. The crushing rollers are driven by gears, and the gears are arranged inside the crushing trough, which will inevitably cause kaolin adhesion. Moreover, the gears are driving components, and the lubricating oil on the gears will also cause kaolin pollution.

[0008] Therefore, a new kaolin cake crusher suitable for online flow operation is needed. Summary of the Invention

[0028] like Figures 1 to 5As shown, a kaolin cake crushing machine suitable for online assembly line operation includes a base, a power source 5, a transmission shaft and a cake crushing mechanism 9. The power source 5, the transmission mechanism 6 and the cake crushing mechanism 9 are installed on the base. The kaolin cake crushing machine includes two sets of cake crushing mechanisms 9, two power sources 5 and two transmission shafts. A single power source 5 drives a single set of cake crushing mechanisms 9 through a single transmission mechanism 6. The transmission mechanism 6 includes a transmission shaft, a reducer, a bearing seat, etc. The bearing seat is arranged on one side of the side frame, and the bearing seat and the cake crushing mechanism 9 are respectively arranged on both sides of the side frame. The side frame is a flat plate design, which can play a certain isolation role for kaolin and prevent kaolin from contacting the bearing seat. The cake crushing mechanism 9 includes a cake crushing shaft 11 and a cake crushing gear 12. Multiple cake crushing gears 12 are arranged at intervals along the length direction of the cake crushing shaft 11. One cake crushing gear 12 on another set of cake crushing mechanism 9 is embedded between two adjacent cake crushing gears 12 on a single set of cake crushing mechanism 9, and the embedded cake crushing gear 12 does not contact the outer circumference of the cake crushing shaft 11 for installing the two adjacent cake crushing gears 12; the kaolin cake crushing machine also includes a scraping structure 7 and an auxiliary cutting piece 8. The scraping structure 7 is arranged between the two adjacent cake crushing gears 12 of the single set of cake crushing mechanism 9. The scraping structure 7 is used to scrape the outer circumference of the cake crushing shaft 11 in the single set of cake crushing mechanism 9. The scraping structure 7 and the other set of cake crushing mechanism 9 are respectively arranged on both sides of the scraped cake crushing mechanism 9, and the auxiliary cutting piece 8 is installed on the scraping structure 7. The auxiliary cutting piece 8 assists in cutting off the kaolin filter cake. Designed specifically for kaolin filter cakes, it prevents equipment jamming caused by kaolin filter cake sticking to the crushing trough and crushing rollers during the crushing process. Discharge is smoother, and the equipment operates normally longer. A discharge port is provided on the base, the length and width of which match those of the cake crushing mechanism 9. To explain the matching, the sum of the widths of the two sets of cake crushing mechanisms 9 installed side by side is approximately equal to the width of the discharge port, and the length of the cake crushing mechanism 9 is approximately equal to the length of the discharge port. Material is fed from vertically above the cake crushing mechanism 9, and after being crushed by the cake crushing mechanism 9 and the auxiliary cutting element 8, it is discharged into the pulping tank through the discharge port and / or the gap between two adjacent scraping structures 7. In actual operation, the kaolin cake crusher of this application is installed directly below the filter press, and the pulping tank is located directly below the kaolin cake crusher. Before the filter press begins unloading, the kaolin cake crusher of this application begins operation a certain amount of time in advance. When the filter press begins unloading, each plate pull causes a piece of filter cake to fall. The filter cake falls directly onto the kaolin cake crusher, where it is immediately sheared and broken down. The broken-down kaolin fragments fall directly into the slurry tank below. This ensures a continuous process where the material is immediately broken down upon arrival and then stirred and dissolved into a slurry. The filter press, cake crusher, and slurry tank operate simultaneously in a continuous flow.In the technology of this invention, the crushing tank can actually be said to be omitted. However, to prevent the kaolin filter cake from entering the next process without being crushed, a scraper structure 7 is installed on the base. Specifically, the support end 14 of the scraper structure 7 provides a barrier. The spacing between two adjacent scraper structures 7 is less than the thickness of a single kaolin filter cake to further prevent it. A further barrier is to raise the height of the mounting end 13 of the scraper structure 7 higher than the top of the cake crushing mechanism 9. From these three aspects, a comprehensive defense line is set up in two axial dimensions and one vertical dimension to prevent the direct "escape" of the kaolin filter cake. The power source 5 is a motor or other equipment.

[0029] The scraper structure 7 includes a mounting end 13, a support end 14, and a scraper end 15. The mounting end 13 and scraper end 15 are connected at both ends of the support end 14. The mounting end 13 is used to secure the scraper structure 7. The scraper end 15 acts on the outer circumference of the crushing shaft 11 in the biscuit crushing mechanism 9, extending below the horizontal cross-section of the biscuit crushing shaft 11 passing through the axis. The mounting end 13 is located at a height higher than the top of the biscuit crushing mechanism 9. Multiple parallel and spaced scraper structures 7 are installed on the outer sides of the two sets of biscuit crushing mechanisms 9, with the spacing between adjacent scraper structures less than the thickness of a single kaolin filter cake. The scraper structure 7 not only removes kaolin adhering to the outer circumference of the biscuit crushing shaft 11 between two adjacent biscuit crushing gears 12 (specifically, this is achieved through the scraper end 15), but also scrapes and cleans the sides of the biscuit crushing gears 12 (specifically, this is achieved through the support end 14). The design that the scraping end 15 extends into the horizontal section below the axis of the biscuit crushing shaft 11 ensures that the scraped material will directly enter the bottom of the biscuit crusher under the action of gravity and will not participate in the operation process of other components of the biscuit crusher.

[0030] An auxiliary cutting piece 8 is welded to the mounting end 13 and the supporting end 14 of the scraper structure 7. The extension length of the auxiliary cutting piece 8 on the supporting end 14 does not exceed the horizontal cross-section of the cake-crushing shaft 11 through the axis. The auxiliary cutting piece 8 is arranged perpendicular to the scraper structure 7. The auxiliary cutting piece 8 has three functions. The first is to perform a simple auxiliary cutting and crushing of the kaolin filter cake between the cake-crushing mechanism 9 and the scraper structure 7; the second is to prevent the kaolin filter cake from directly contacting the surface of the scraper structure 7, thereby reducing adhesion to the surface of the scraper structure 7 to a certain extent; and the third is to prevent deformation of the scraper structure 7. After all, the scraper end 15 of the scraper structure 7 needs to exert a certain degree of force during the scraping process.

[0031] A gap D is provided between the scraping end 15 and the outer circumference of the biscuit-crushing shaft 11, and the gap D is greater than 5 mm and less than 25 mm. Such a spacing is set to ensure the scraping effect of the scraping end 15 on the outer circumference of the biscuit-crushing shaft 11.

[0032] The biscuit gear 12 includes a gear plate 16, an external gear part 17 and an internal gear part 18. There are two gear plates 16, and the gear plate 16 is provided with an inner hollow circle and outer circumferential teeth. The two gear plates 16 are arranged in parallel, and the internal gear part 18 is welded on the inner hollow circle of the two gear plates 16. A limiting groove 22 is provided on the inner side of the circumference of the internal gear part 18, and a limiting boss is provided on the outer circumference of the biscuit shaft 11. The limiting groove 22 is connected to the limiting boss, and the external gear part 17 is welded on the outer circumferential teeth of the two gear plates 16. The external gear part 17 changes with the tooth shape of the outer circumferential teeth. There are multiple external gear parts 17, and the multiple external gear parts 17 are connected in sequence. One outer circumferential tooth on the gear plate 16 corresponds to one external gear part 17. First, the hollow structure of the biscuit crushing gear 12 reduces its manufacturing cost. Second, the retaining groove 22 of the biscuit crushing gear 12 prevents the biscuit crushing shaft 11 from idling relative to the biscuit crushing gear 12. Third, the kaolin filter cake itself does not require high crushing requirements, so this structure of the biscuit crushing gear 12 fully meets these requirements. The outer gear 17 changes with the tooth profile of the outer circumferential teeth, while the inner gear 18 is a hollow cylinder. The outer gear 17 and the inner gear 18 are designed to completely seal the space between the two gear plates 16, preventing kaolin from entering the internal cavity of the biscuit crushing gear 12.

[0033] A crushing end 21 extends from one end of the outer gear member 17. The outer circumferential teeth include a first side 19 and a second side 20. The first side 19 is shorter than the second side 20, and the crushing end 21 is located on a straight extension of the first side 19. The two sets of biscuit crushing mechanisms 9 rotate relative to each other and have identical structures. There is no size difference between the biscuit crushing gears 12.

[0034] The base includes a basic chassis 1 and a mounting frame, which are respectively arranged in the length direction of the base. The basic chassis 1 is a planar structure, and a power source 5 and a transmission shaft are installed on the basic chassis 1. The mounting frame includes a chassis, a side frame and a mounting bar 4. The chassis is composed of two parallel steel bars, and a side frame is vertically connected to each end of the length of the steel bar. A cake crushing mechanism 9 is installed on the two side frames, and the mounting bar 4 is connected between the two side frames. The scraping structure 7 is fixedly connected to the mounting bar 4.

[0035] The kaolin cake crushing machine further includes an auxiliary frame 10, which is mounted on the base. There are two auxiliary frames 10, one on each side of the base in the width direction, and two sets of cake crushing mechanisms 9 are mounted between the two auxiliary frames 10. The fundamental function of the auxiliary frame 10 is to solve the matching problem with the filter press. The width of the filter press is fixed. In order to achieve streamlined operation, the auxiliary frame 10 is to match the existing width of the filter press, rather than changing the structure of the filter press on the basis of this application.

[0036] The spacing between two adjacent cake-breaking gears 12 on a single set of the cake-breaking mechanism 9 is smaller than the thickness of the kaolin filter cake, so as to prevent the kaolin filter cake from falling between the two adjacent cake-breaking gears 12, where it would be easily stuck.

[0037] There is a spacing L between the width sides of the scraping structure 7 and the adjacent biscuit gears 12, and the spacing L is greater than 2mm and less than 15mm. Such a spacing is set to ensure the scraping effect of the support end 14 on the side of the biscuit gear 12.
