Description

Technical Field

[0001] This invention relates to the field of special equipment for the production of energy-saving building materials, and in particular to a special vertical grinding equipment for the production of energy-saving ceramic slurry materials for building materials. Background Technology

[0002] Ceramic materials for construction generally require processes such as raw material preparation, powder making, molding, drying, glazing or decoration, high-temperature firing, and post-processing. Among these, the raw material preparation and powder making steps refer to the preliminary crushing and impurity removal of raw materials such as kaolin, porcelain clay, feldspar, and quartz; or the extraction of soil and mud blocks from suitable riverbed soil areas, crushing and removing impurities, and then mixing the coarse powder obtained by the above methods into a coarse powder slurry, that is, a mud mixture with different particle sizes, and then feeding it into a ball mill for grinding, so that it is ground into a finer and more uniform powder slurry, i.e., ceramic slurry, and then fed into the next molding step.

[0003] Traditional ceramic slurry ball mills use a horizontal ball mill. It consists of a horizontally positioned cylindrical mill with a central axis. The operator pours coarse slurry into the mill, adds grinding balls, seals the mill, and then uses a motor to drive it to rotate at low speed around the central axis. The coarse slurry is repeatedly impacted and ground between the grinding balls and the mill wall, thus becoming an ultrafine slurry. This process typically lasts for more than 24 hours. The operator then stops the machine, opens the mill's outlet, and discharges the ultrafine ceramic slurry. If the particle size and fineness of the slurry do not meet the requirements, it is injected into another horizontal ball mill, and the grinding process is repeated until the output slurry is suitable.

[0004] However, this horizontal grinding method requires a closed-loop rolling grinding process. After a batch, the machine will spend most of its time operating independently, no longer accepting external slurry input. Furthermore, the grinding effect needs to be assessed by exporting slurry samples after each grinding cycle, combined with experience, resulting in low reliability and a lack of intuitiveness. Due to the high material consumption, it's rare to operate a single horizontal machine; instead, dozens of horizontal grinding machines are often operated simultaneously for batch processing. Companies also need to install numerous slurry buffer tanks and slurry pools to address the storage of the large batches of ceramic slurry produced. Therefore, the production system occupies a huge area, has very slow operating efficiency, and high overall energy consumption. Summary of the Invention

[0005] The purpose of this invention is to provide a special vertical grinding equipment for the production of energy-saving ceramic slurry materials for building applications, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A vertical grinding equipment for producing energy-saving ceramic slurry materials for building applications includes: The feeding module has a coarse slurry output end; A grinding module, comprising a vertical grinding mill, the vertical grinding mill including: The grinding cylinder is set vertically as a whole. The slurry input end is located on the lower side of the grinding cylinder; The spiral lifting shaft includes a shaft with its central axis coaxial with the grinding cylinder, and lifting blades spirally arranged around the shaft. The lifting blades are used to rotate and lift the slurry at the bottom of the grinding cylinder to the upper side inside the grinding cylinder. The slurry output end is located on the upper side of the grinding cylinder and is higher than the uppermost end of the lifting blades; A spiral power unit, which is connected to the spiral lifting shaft, drives the spiral lifting shaft to rotate; Second slurry tank; The coarse slurry output end is connected to the slurry input end, and the second slurry tank is connected to the slurry output end.

[0007] The beneficial effects of this invention include: During operation, the feeding module outputs the coarse powder slurry, which has been preliminarily crushed and coarsely ground, from the coarse powder slurry output end and sends it to the grinding module. The vertical grinder in the grinding module performs vertical grinding. Specifically, the coarse powder slurry is input into the grinding cylinder from the lower side. Auxiliary grinding materials such as grinding balls are placed in the grinding cylinder in advance. The spiral lifting shaft rotates under the drive of the spiral power device, stirring, lifting, and settling the coarse powder slurry and auxiliary grinding materials together in the grinding cylinder. During this operation, the coarse particles in the coarse powder slurry are gradually ground into finer particles, and the particle size of the slurry in the cylinder changes, forming a separation phenomenon where extremely fine particles rise and larger particles sink. Under the lifting action of the lifting blades of the spiral lifting shaft, the light slurry is stirred and agitated, thus overflowing from the slurry output end as an overflow port and finally flowing into the second slurry pool. The turbid liquid with a higher specific gravity, because it cannot be agitated and overflowed, returns to settling and continues to participate in grinding until its particle size is ground into finer particles, meeting the mass conditions for being agitated, thrown out, and overflowed, and then naturally continues to be output from the slurry output end. Throughout the process, the slurry in the grinding module is dynamically input and output, without affecting the continuity of other production processes. It does not require other machines to be paused or waited for, and operators can dynamically and visually observe the fine slurry output from the slurry outlet. This makes it easier to control slurry quality compared to the closed grinding process of traditional horizontal ball mills. Because this invention uses dynamic open grinding, it reduces system machine waiting time and improves work efficiency, thus offering greater energy savings compared to traditional ceramic slurry material preparation equipment.

[0008] In some extended embodiments, the upper part of the grinding cylinder is closed by an upper cover plate, and the side of the upper cover plate is provided with a grinding ball inlet, which is obliquely facing the central axis of the grinding cylinder.

[0009] The top cover plate, which seals the upper part of the grinding cylinder, prevents the lightweight slurry, which is lifted and splashed up by the lifting and stirring action of the spiral lifting shaft, from overflowing from directly above. Instead, it directs the slurry out through the slurry output end located on the side. Besides its blocking function, this also ensures a consistent flow rate, as the amount of slurry splashed from directly above is less than the amount that overflows from the side. As the slurry in the cylinder is consumed, the feeding module continuously and dynamically feeds new coarse slurry into the cylinder from the slurry input end for further grinding. A grinding ball inlet on the side of the top cover plate allows operators to easily add grinding materials, such as high-alumina balls, into the cylinder. The grinding ball inlet is angled towards the central axis of the grinding cylinder to ensure that the added grinding material is placed into the slurry at a suitable angle, avoiding impact and collision with the cylinder wall and premature wear of the grinding material.

[0010] In some extended versions, the slurry output end is horizontally positioned.

[0011] Since it is not suitable to directly set up a negative pressure pump for suction in the extended scheme, setting the slurry output end at this angle can better match the splash overflow angle of the slurry and meet the requirement of naturally receiving the overflow of light and fine slurry.

[0012] In some extended embodiments, the inner sidewall and bottom inner wall of the grinding cylinder are both covered with rubber liners. The rubber liners serve two main purposes: firstly, they protect the inner sidewall and bottom inner wall of the grinding cylinder, preventing excessive wear and tear on the cylinder due to collisions with the grinding materials and incompletely broken hard objects in the slurry; secondly, they also provide some noise reduction.

[0013] In some extended embodiments, the vertical grinding mill further includes a first inspection port and a second inspection port. The first inspection port is opened horizontally along the axis on the lower side of the grinding cylinder. The second inspection port is opened at the slurry input end, and the opening of the second inspection port is inclined upward.

[0014] By providing a first and a second inspection port, operators can easily inspect the inside of the grinding cylinder for issues such as blockages or material shortages. Since blockages often occur at the bottom of the grinding cylinder and near the inlet for feeding coarse slurry, the first inspection port is horizontally positioned on the lower side of the grinding cylinder, and the second inspection port is angled upwards at the slurry inlet.

[0015] In some extended embodiments, the helical power unit includes: The cylinder base, which is in the shape of a vertical cylinder, is positioned above the grinding cylinder; A geared motor is located above the cylinder base, with its power output end facing downwards; A coupling assembly, disposed within the cylindrical base, connects the power output end of the geared motor to the upper end of the shaft.

[0016] In this extended design, the geared motor is actually mounted upside down on top of the grinding cylinder, saving installation space. Using the cylinder base as a support, the geared motor is connected to the upper end of the grinding cylinder, and a coupling assembly located in the cylinder base connects the power output end of the geared motor to the upper end of the shaft. This not only protects the coupling assembly and other gaps where mud and sand can easily seep in, but also transmits rotational power to the vertical spiral lifting shaft via a very short path, avoiding power loss.

[0017] In some extended embodiments, the feeding module is positioned at the front and the second slurry tank at the rear. The grinding module includes two or more vertical grinding mills connected in series from front to back. The slurry output end of the preceding vertical grinding mill is connected to the slurry input end of the following vertical grinding mill via a slurry buffer tank. The slurry input end of the vertical grinding mill at the very front of the grinding module is connected to the coarse powder slurry output end, and the slurry output end of the vertical grinding mill at the very back of the grinding module is connected to the second slurry tank.

[0018] In practical applications, even slurry selected through the lifting and splashing of vertical grinders may not meet the fine particle size requirements of ceramic raw material. Therefore, this equipment can connect multiple vertical grinders in series. When one grinder outputs slurry, it is temporarily stored in a slurry buffer tank. Then, using a pump, the slurry is transferred to the next grinder for further grinding and refinement until the final slurry meets the requirements and is then transferred to a second slurry tank for later use. This multi-stage series design results in a finer ceramic raw material, meeting the needs of different end products. Furthermore, the entire production line maintains dynamic input and output, eliminating the energy-consuming components of sealed tanks, timed stirring, and centralized delivery. The connected sub-units can be easily modified by changing the pipeline connections.

[0019] It should also be noted that the relative front and relative rear mentioned here refer to the relative front and rear based on the logical forward direction of the slurry production line, and not to the front and rear direction of each machine in the equipment on the spatial coordinates. Therefore, in the layout of the plant site, there may be bends, turns and other pipeline layouts, but logically, as the source, the feeding module is still considered to be in the relative front, and similarly, the second slurry tank is still considered to be in the relative rear.

[0020] In some extended embodiments, the feeding module includes a feeder, a horizontal ball mill, and a first slurry tank. The feeder is connected to the inlet of the horizontal ball mill via a conveyor belt, and the outlet of the horizontal ball mill is connected to the first slurry tank. The grinding module obtains slurry from the first slurry tank.

[0021] During operation, the feeder receives the mixed material from the previous process, which includes mud, gravel, etc. After crushing by the feeder, the mixed material falls onto the conveyor belt, which then feeds it into the horizontal ball mill. Grinding materials such as high-alumina balls and water are added according to production requirements for short-term coarse grinding. The resulting coarse powder slurry is output from the outlet of the horizontal ball mill and falls into the first slurry tank for temporary storage, preparing material for the subsequent vertical grinding mill. Because only one horizontal ball mill is used and only coarse grinding is performed, the time loss for the entire process is minimal, resulting in good energy-saving effects. Furthermore, it ensures that the particle size of the slurry entering the vertical grinding mill meets the standard requirements for coarse powder particle size. In addition, this extended solution allows for the modification of existing horizontal ball mill installation sites, avoiding the waste of equipment output value caused by the complete obsolescence of horizontal ball mill units.

Detailed Implementation

[0024] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

Therefore, they should not be construed as limiting this invention.

[0027] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0028] Several embodiments of the present invention are described below.

[0029] Reference Figures 1 to 2 This invention discloses a vertical grinding device for producing energy-saving ceramic slurry materials for building applications, comprising a feeding module, a grinding module, and a second slurry tank 300. The feeding module has a coarse slurry output end, which receives the conveyed soil lumps, performs a certain crushing and impurity removal process, and then outputs the coarse slurry from the coarse slurry output end. The grinding module includes a vertical grinder 100, which has a slurry input end 102 at the lower end and a slurry output end 104 at the upper end. After the coarse slurry is input into the vertical grinder 100 from the slurry input end 102, it undergoes immediate vertical stirring and grinding in the vertical grinder 100. The slurry tumbles, rises, and settles within the machine, and the soil particles and impurities are gradually crushed into ultrafine particles with a fine particle size. The relatively light part of the slurry will surge and splash in the upper part of the machine due to the lifting effect of vertical stirring, and thus be output from the slurry output end 104. These lightweight, overflowing slurries, after multiple grinding processes, can be used as the ceramic raw material and sent to the second slurry tank 300 for storage.

[0030] In some embodiments, the feeding module includes a feeder 400, which includes a hopper, a crushing device, a vibrating screen device, and a discharge port. The crushing device includes an upper jaw crushing assembly and a lower roller crushing assembly. The jaw crushing assembly has a stationary jaw and a movable jaw. The movable jaw reciprocates under the drive of an external power source, crushing the falling soil clods. The soil clods then fall downwards into the roller crushing assembly. The roller crushing assembly includes two or more rollers arranged in the same direction and rotating in opposite directions, with a fixed spacing between the rollers. Soil clods fall into the gap between the rollers and are sheared and crushed by the rollers into particles with an average particle size of about 0.5 to 3 mm. The particles fall onto the vibrating screen device located below the roller crushing assembly. The screen of the vibrating screen device vibrates, further separating the particles. Small particles of the appropriate particle size fall from the discharge port onto the conveyor belt 401 located below the feeder 400. Excessive particles are intercepted and discharged from other angles, preventing them from falling onto conveyor belt 401.

[0031] The conveyor belt 401 has a front end and a rear end. The front end of the conveyor belt 401 is relatively lower than the rear end and is located below the discharge port. It receives the initially crushed soil material and, as the conveyor belt 401 rotates, the material is continuously lifted to a higher position at the rear end before falling downwards. A horizontal ball mill 402 is installed at the material discharge position. The horizontal ball mill 402 can be a traditional horizontal mill. That is, after the required amount of crushed soil is added, grinding materials such as high-alumina balls are added, water is added, and horizontal stirring is carried out. After a set stirring time, the machine is stopped and coarse powder slurry is output. Since the subsequent grinding modules of the vertical grinding unit are used in series in this embodiment of the invention, the number and stirring time of the horizontal ball mills 402 added here do not need to work like the traditional parallel array of large horizontal ball mill units. Only a short stirring is required to output coarse powder slurry. Therefore, even if the horizontal ball mill 402 is added, it will not have a significant negative impact on the production rhythm or energy efficiency. The horizontal ball mill can pre-process and prepare the coarse slurry. The subsequent vertical grinding process requires the slurry to rise and overflow before being fed into the next stage of the series. Therefore, the initial coarse slurry has certain requirements for fineness, and the horizontal ball mill 402 can ensure this requirement is met. Alternatively, in some embodiments, a fixed mixing tank with built-in agitators and a water injection device can be directly used to mix the crushed soil particles in situ, which also meets the production requirements of the coarse slurry. After the coarse slurry is prepared, it is temporarily stored in the first slurry tank 302. The first slurry tank 302 is equipped with a static agitator for slow stirring, ensuring uniform distribution of suspended particles and preventing sedimentation and clumping.

[0032] In some embodiments, a grinding module is provided behind the feeding module, and the grinding module includes multiple vertical grinders 100 connected in series. Each vertical grinder 100 includes a grinding cylinder 101 with a central shaft, the lower end of which is mounted on a base, and the upper end of which is closed by a cover plate. That is, the grinding cylinder 101 is entirely enclosed, and slurry input and output are only completed through several pre-set openings. A slurry input end 102 is provided on the lower side of the grinding cylinder 101. This slurry input end 102 is used to receive slurry transported from the previous process. Similarly, a first inspection port 107 is provided on the lower side of the grinding cylinder 101, and a slurry output end 104 is horizontally arranged on the side wall of the grinding cylinder 101 near the top. Above the upper cover plate, a cylinder base 200 is provided. A reducer 202 is located directly above the cylinder base. A stirring motor 201 is fixedly connected to the reducer 202. The power output shaft of the stirring motor 201 is connected to the reducer 202, and the output shaft of the reducer 202 serves as the power output end of the motor device. It is connected to the spiral lifting shaft 103 via a coupling assembly located within the cylinder base 200. The spiral lifting shaft 103 is suspended entirely within the grinding cylinder 101, coaxial with its central axis. The spiral lifting shaft 103 has a shaft rod 1031 and lifting blades 1032 spirally extending around the shaft rod 1031. The lifting blades 1032 have a double-helix structure, and their rotation direction matches the output torque of the stirring motor 201. The rotation of the stirring motor 201 drives the spiral lifting shaft 103 to rotate, thereby stirring and lifting the slurry within the grinding cylinder 101 by the lifting blades 1032, causing it to surge upwards from the bottom. The lifting blades 1032 have a gap in the radial direction between themselves and the inner wall of the grinding cylinder 101. Therefore, after the slurry is lifted, it settles around the inside of the grinding cylinder 101, resulting in slurry splashing at the top of the grinding cylinder 101. Furthermore, the slurry is a complex mixed suspension; its relatively light weight and fine particle size make it prone to splashing. Therefore, in this embodiment, the slurry output end 104, located near the top of the side wall of the grinding cylinder 101, allows the relatively clear liquid that has been stirred and sorted to overflow, while the relatively turbid liquid with a larger mass settles and continues to be stirred and ground until it can be lifted and overflowed. The particle size and mass of the overflowing slurry can be controlled by adjusting the stirring speed, the amount of grinding media, and the number of vertical grinding mills 100 in the series assembly.

[0033] The structure of multiple vertical grinding mills 100 connected in series refers to connecting a series of vertical grinding mills 100 sequentially with the direction of material intake as the relative front, that is, in this embodiment, with the direction of the feeding module as the relative front, and the direction of the final ceramic slurry output as the relative rear. Of course, in order to temporarily store the slurry so that the process can be buffered and controlled to avoid congestion and uncontrollability, a slurry buffer tank 301 can be set between two adjacent vertical grinding mills 100. Specifically, if the vertical grinding mill 100 that directly receives the coarse powder slurry from the feeding module is regarded as the first machine, and the vertical grinding mill 100 connected to the first machine is regarded as the second machine, then the slurry input end 102 of the first machine is connected to the first slurry tank 302 through a pipeline. The coarse powder slurry is drawn from the first slurry tank 302 by the delivery pump 500 installed in the pipeline, and then sent into the first machine from the slurry input end 102 of the first machine. The relatively fine slurry overflowing from the slurry output end 104 of the first mill is then piped into the slurry buffer tank 301. The slurry input end 102 of the second mill is connected to the bottom of the slurry buffer tank 301 via a pipe, and then the slurry is pumped into the second mill by a separate delivery pump 500 for a second grinding and mixing. Following this principle, a series array is rationally arranged until the slurry output end 104 of the last vertical mill 100, which delivers the qualified slurry from that mill into the second slurry tank 300.

[0034] The grinding cylinder 101 of the vertical grinder 100 has an inclined grinding ball inlet 105 on top. Through this window, grinding materials, such as high-alumina balls, can be added into the grinding cylinder 101. High-alumina balls are a type of wear-resistant grinding media with high-purity alumina as the main component, which is already available in the prior art. They are placed in the horizontal ball mill 402 or the vertical grinder 100 and rotated and stirred together with the slurry. Through the collision and friction between the balls, solid particles such as clay and minerals in the slurry are efficiently crushed and evenly dispersed, ultimately forming a fine and stable ceramic slurry. High-alumina balls have high hardness, wear resistance, and strong chemical stability, which can significantly improve grinding efficiency and ensure the quality of the slurry.

[0035] In some embodiments, the grinding cylinder 101 of the vertical grinder 100 is further provided with a first inspection port 107 and a second inspection port 108. The first inspection port 107 is located at the lower part of the side wall of the grinding cylinder 101, and the second inspection port 108 is obliquely opened at the upper part of the slurry input end 102, intersecting the axis of the slurry input end 102. The lowermost end of the spiral lifting shaft 103 is suspended above the bottom plate of the grinding cylinder 101 and does not directly contact the bottom plate of the grinding cylinder 101. This is to allow the fluid to form a lifting and lowering circulation inside the cylinder. However, this also makes it easy for large particles to form sediments that are difficult to float. Therefore, when the detection instrument detects that there is too much sediment at the bottom of the grinding cylinder 101, or when a fixed schedule of maintenance is performed based on experience and sediment accumulation is found, the first inspection port 107 can be opened to clean the material inside the cylinder and inspect the wear and tear of the internal components. Similarly, the slurry input from the slurry input end 102 is often coarse powder slurry with relatively large particle size, so it is also easy to form blockages near the slurry input end 102. At this time, these blockage locations can also be cleaned and repaired through the second inspection port 108.

[0036] Unlike the vertical spiral mixers used in general mining, this embodiment of the invention is a complete set of vertical grinding equipment specifically designed for the production of ceramic slurry materials for construction. The requirements for the slurry's input and output states differ from those of ordinary crushing processes in mining. This process demands finer powder and higher purity from the slurry. Furthermore, this embodiment connects multiple vertical grinding mills 100 in series, breaking away from the conventional parallel horizontal ball mill array arrangement system structure in ceramic slurry preparation, and also differing from the usual application scenario of a single vertical spiral mixer in mining. Finally, vertical spiral mixers used in general mining often carry large-particle slurry composed of coarse stone and slag inside their drums. These particles are prone to settling and accumulating at the bottom of the drum without being lifted. Therefore, a water-assisted impact structure is required to help lift them. However, in this embodiment, the vertical grinder 100 receives a fine slurry. Even the coarse powder slurry injected into the first machine in the series has been pre-ground by the horizontal ball mill 402 and pre-settled by the first slurry tank 302. Therefore, there is no need to set up an additional water-assisted impact structure at the bottom of the drum. This saves space for setting up maintenance ports and other facilities, improving the convenience of equipment maintenance.

[0037] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described.
