Description

Technical Field

[0001] The invention belongs to the technical field of wet pulverizing of building ceramics, and in particular relates to high-efficiency wet pulverizing production equipment for building ceramics. Background Art

[0002] The dry powder making process is a powder making technology used in the production of building ceramics. Its process is summarized as follows: raw material crushing, batching, fine grinding, screening, wet granulation, screening, aging, dry pressing and sintering.

[0003] At present, there are two common powder making processes in my country's building ceramics industry, one is dry powder making and the other is wet powder making. Wet powder making is now widely used in the industry. Due to the problems of high energy consumption, high pollution, high emission and energy conservation and emission reduction in wet powder making, there is also the reality that continuous coal burning in the powder making process urgently needs to upgrade the powder making process technology. In the building ceramics industry, dry powder making has the advantages of low energy consumption, low emission and no pollution compared with wet powder making. However, its wet granulation process has the technical bottleneck of unstable output and quality. In the dry powder production, the product is prone to cracks and large damage, which has led to the inability to widely promote dry powder making technology in the building ceramics industry.

[0004] Wetting pulverizing is an upgraded technology of the existing dry pulverizing. In the existing wetted pulverizing technology equipment, a turntable is used to guide the material at the bottom of the wetting tower, which will result in high failure rate and low output. At the same time, there is also a problem of low material discharge in the discharge stage. Even if the discharge amount is increased, the dispersion will be uneven, resulting in poor wetting effect in the later wetted pulverizing link. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0031] Reference Figures 1 to 10 As shown, this embodiment provides an efficient wetting production equipment for building ceramics wet powder making, including an elevator 1, the outlet of the elevator 1 is connected to the powder storage bin 2, the bottom of the powder storage bin 2 is connected to a plurality of powder supply and dispersion components 3, the plurality of powder supply and dispersion components 3 are connected to the top of the wetting tower body 4, the fine water mist component 320 built into the wetting tower body 4 is connected to the water supply system 5, the bottom of the wetting tower body 4 is fixed with a constant pressure dust removal chamber 6, the constant pressure dust removal chamber 6 is connected to the dust collector 7 through a negative pressure pipe, and the discharge port of the dust collector 7 is connected to the dust collector 7. It is connected to the air flow channel 101 of the elevator 1, and a wind-locking discharge cone 604 is installed at the bottom of the wetting tower body 4. The discharge port of the wind-locking discharge cone 604 is equipped with a first conveyor 8. The output end of the first conveyor 8 is connected to the drum screen device 9. The output port of the drum screen device 9 is provided with a second conveyor 10. The output end of the second conveyor 10 is connected to several powder awakening bins 11. A third conveyor 12 is provided at the bottom of the powder awakening bin 11. The output end of the third conveyor 12 is cooperatively connected with the fourth conveyor 13.

[0032] The powder enters the powder storage bin 2 through the elevator 1. The discharge port of the elevator 1 is directly connected to the powder storage bin 2 in a sealed manner. In this embodiment, the lifting capacity of the elevator 1 is designed to exceed 20% of the wetting output of the wetting tower 4. Upper and lower material level meters 201 are installed on the annular surface of the powder storage bin 2 to provide information reference for the automatic feeding of the elevator 1. The powder storage capacity of the powder storage bin 2 is preferably 1.2 to 1.5 times the hourly wetting and powder production output of the wetting tower 4. A high-density PE anti-sticking sheet can be optionally attached to the inner surface of the powder storage bin 2 as needed. The powder storage bin 2 is supported by four support columns. Several powder supply and dispersion components 3 connected to the bottom of the powder storage bin 2 can evenly disperse the powder into the wetting tower 4. In this embodiment, the design of the powder supply and dispersion components 3 is preferably 3, 4, 5, or 6. When facing a production line with a large amount of powder production, the powder supply and dispersion components 3 can be added to achieve uniform dispersion of a large amount of powder. When the production line with a smaller amount of powder production is required, the powder supply and dispersion components 3 can be reduced to adapt. Similarly, to meet varying milling capacity requirements, the water volume supplied by the water supply system 5 is adjusted accordingly (increasing the water supply for larger milling volumes and decreasing it for smaller milling volumes). Before entering the water supply system 5, tap water is preheated to a temperature of 40°C to 60°C by a hot water boiler 501, increasing it to 50°C in this embodiment. Five production levels are specifically established based on the system's milling capacity: 20 tons, 30 tons, 40 tons, 50 tons, and 60 tons per hour of wetted milling capacity. These correspond to wetting tower 4 diameters of 3m, 4m, 4.5m, 5m, and 5.5m. A constant-pressure dust removal chamber 6 at the bottom of the wetting tower 4 precisely separates powder that doesn't meet wettability standards, allowing it to pass through a dust collector 7 and re-enter the elevator 1, completing a closed milling cycle. This reduces manual intervention while achieving more standardized, automated, and intelligent production. The powder that meets the wetting standard is sent to the drum screen device 9 through the first conveyor 8 for powder particle size screening, and the second conveyor 10 sends the powder of qualified size to the powder awakening bin 11. In this embodiment, the powder is sent to the powder awakening bin 11 for awakening for 24 hours. If tap water at room temperature (10℃~25℃) is used, it will take 36 hours to 48 hours to awaken. During the awakening process, the moisture in the powder is further evenly distributed in the powder through natural infiltration and diffusion, reducing or avoiding the problem of uneven shrinkage, cracking or deformation of the powder due to uneven moisture distribution in the subsequent forming process. In this way, the physical and chemical properties of the powder can be improved before the forming process, internal stress can be released, the stability and green body quality in the subsequent forming process can be improved, and the quality of the final product can be enhanced.A third conveyor 12 is provided at the bottom of each powder awakening bin 11. The awakened powder falls onto the third conveyor 12 through the outlet at the bottom of the powder awakening bin 11. The third conveyor 12 then guides the powder uniformly onto the fourth conveyor 13 for subsequent forming processes. The main body of the powder awakening bin 11 is square, with a surface at the bottom extending vertically downward from a surface of the main body. The other three surfaces can be inclined to form the outlet of the powder awakening bin 11 according to the required powder output. By adjusting the number of powder supply and dispersion components 3, the water supply of the water supply system 5, the dust removal power of the dust collector 7, and the diameter of the wetting tower 4, it is possible to formulate a feasible plan for production lines with different powder production requirements. This provides a preliminary solution and paves the way for the problem of different demand quantities encountered in the subsequent promotion of dry wet powder production technology.

[0033] Further optimization scheme, the powder supply and dispersion component 3 includes a cloth component, the cloth component is connected to the powder storage bin 2, the bottom of the cloth component is connected to a cylindrical diffuser, the cylindrical diffuser is connected to the wetting top plate 401 of the wetting tower body 4, the output end of the blower 303 is connected to an air duct 304, the air duct 304 is divided into a horizontal section and a vertical section, the horizontal section extends horizontally into the cylindrical diffuser and extends to the center of the cylindrical diffuser, one end of the vertical section is connected to the horizontal section The other end of the longitudinal section extends downward to below the wetting top plate 401, and the bottom ends of several longitudinal sections are fixedly connected with a punching plate 310. The longitudinal section is provided with a first air outlet group 3041, a second air outlet group 3042, and a third air outlet group 3044 from top to bottom, and a number of inclined air guide pipes 3043 are arranged between the second air outlet group 3042 and the third air outlet group 3044. The several inclined air guide pipes 3043 are connected to the longitudinal section.

[0034] The material distribution assembly consists of a sub-cone 301, a feeder 302, and a conical tube 305. The top of the sub-cone 301 is fixedly connected to the powder storage bin 2, and the bottom of the sub-cone 301 is gap-fitted with the feeder 302. The top of the conical tube 305 is connected to the discharge port of the feeder 302 and is detachably connected. The bottom of the conical tube 305 is connected to the top of the cylindrical disperser and is detachably connected or fixedly connected. The feeder 302 is preferably a rotary feeder. The bottom of the conical tube 305 is approximately 20% smaller than the top opening. The conical tube 305 is preferably a square cone 305. This allows the square cone 305 to dampen the powder at the conical tube 305 when the feeder 302 rotates to prevent it from falling rapidly, thereby forming a stable and continuous powder supply. The bottom of the cylindrical disperser is connected to the wetting top plate 401 at the top of the wetting tower 4, facilitating further dispersion and wetting of the powder after it is dispersed. The edge of the perforated plate 310 is approximately 500 mm from the inner wall of the wetting tower body 4, and the perforated diameter and hole spacing are both approximately 20 mm. When there are multiple air ducts 304, a single blower 303 can be shared by using branch pipes, or multiple blowers 303 can be configured to correspond to the multiple air ducts 304, depending on the actual situation. The blowers 303 are preferably installed at the top of the wetting tower body 4. The horizontal section of the air duct 304 forms a cross with the transmission direction of the rotary feeder, facilitating rapid dispersal of the material from the rotary feeder in the horizontal section. The vertical section extends downward to the interior of the wetting tower body 4 for approximately 500 mm and is sealed at its bottom. The first and second air outlet hole groups 3041, 3042, and inclined air guide tubes 3043 on the vertical section are positioned at the same distance from the connection point with the air delivery tube 304. The diameters of these openings and the diameter of the air delivery tube 304 are both approximately 10 mm. A group of annular holes with a diameter of 10 mm is drilled at the bottom of the vertical section within the wetting tower body 4. The holes are arranged in two to four vertical rows. This ensures a good powder dispersion effect and provides better conditions for subsequent wetting of the powder.

[0035] According to a further optimization scheme, the bottom ends of the plurality of inclined air guide tubes 3043 are flush with the top of the uppermost opening of the third air outlet group 3044 .

[0036] The inclined air guide pipe 3043 is arranged in an oblique downward direction. The holes opened on the longitudinal section can fully disperse the powder nearby. The powder farther away from the longitudinal section will be further dispersed by the wind drawn out by the inclined air guide pipe 3043. At the same time, it is also beneficial for the powder to be blown down by the wind when passing through the punching plate 310, thereby avoiding the accumulation of material on the punching plate 310 farther away from the longitudinal section.

[0037] According to a further optimization scheme, the wind guide inclined ducts 3043 are distributed in an umbrella shape.

[0038] The inclined air guide pipes 3043 are distributed in an umbrella shape, which can disperse and blow down the powder in the farther circumferential range of each longitudinal section. The angle between the inclined air guide pipes 3043 and the air supply pipe 304 of the longitudinal section is 45° to 60°, which can achieve the maximum range of powder dispersion and prevention of powder accumulation.

[0039] A further optimized solution is provided, in which a support rod 3205 is fixedly connected to the bottom of the punching plate 310, and a plurality of pull rings are fixedly connected to the support rod 3205. The plurality of pull rings are vertically distributed on the support rod 3205, and the upper pull ring is hung with an upper fine water mist assembly 3201 through a hook, and the lower pull ring is hung with a lower fine water mist assembly 3203 through a hook. Both the upper fine water mist assembly 3201 and the lower fine water mist assembly 3203 are detachably connected to the outside of the wetting tower body 4 through a disassembly part, and both the upper fine water mist assembly 3201 and the lower fine water mist assembly 3203 are connected to the water supply system 5.

[0040] The top of the support rod 3205 is fixedly connected to the bottom of the punching plate 310. The pull rings on the support rod 3205 are installed at upper and lower intervals. The number of pull rings is adjusted according to the amount of wetting and powdering required. In this embodiment, two pull rings are set. The upper fine water mist component 3201 and the lower fine water mist component 3203 both include a number of water branch pipes. The nozzle seats are welded at intervals of about 200mm from the top 200mm position to the end 300mm position of the water branch pipe. The nozzle seats at each installation point are at an angle of 120 degrees, downward in the cross section of the water branch pipe. Two nozzle holders are installed in the direction of the tower. Each nozzle holder can be equipped with one nozzle or 2-3 nozzles depending on the water demand. The number of spray nozzles is calculated based on the water spray volume of each nozzle and the moisture content of the wet powder production, which is approximately 9%. The number of water branch pipes is also calculated based on the diameter of the wetting tower. The water branch pipes are hung on the upper pull ring 3206 and the lower pull ring 3207 respectively through the hooks at the top. The water branch pipes form an angle of approximately 25° with the tower wall within the wetting tower, forming a double-layer umbrella-shaped spray unit. This angle allows the powder to slide down quickly when it falls on the water branch pipe, preventing powder accumulation. The bottom end of the water branch pipe extends outside the tower body through the opening of the wetting tower body 4 and is detachably connected to the fixing fixture fixed to the tower body. The fixing fixture is used to fix the water branch pipe.

[0041] To further optimize the solution, the water supply system 5 includes a connecting hose 3202, and the upper fine water mist component 3201 and the lower fine water mist component 3203 are both connected to the water supply ring pipe 3204 through the connecting hose 3202, and the water supply ring pipe 3204 is connected to the water supply machine system through a pipeline.

[0042] The branch water pipes are connected to the water supply ring pipe 3204 via high-pressure hoses 3202 and valves. This allows for subsequent removal and maintenance of individual branch water pipes, saving time and costs compared to requiring workers to enter the wetting tower for maintenance. The water supply system 5 provides the water supply pipes with a high-pressure water source with a particle size of less than 0.2 mm.

[0043] Further optimization plan, the constant pressure dust removal chamber 6 includes a negative pressure ring silo 601, a discharge port 605 is opened in the middle of the negative pressure ring silo 601, the bottom of the outer ring surface of the wetting tower body 4 is adapted to the discharge port 605, and a negative pressure silo outlet 602 is opened on the outer ring surface of the negative pressure ring silo 601. The negative pressure silo outlet 602 is detachably connected to the negative pressure pipe, and a wind-locking discharge cone 604 is fixed to the bottom of the outer ring surface of the negative pressure ring silo 601. The first conveyor 8 is located below the bottom outlet of the wind-locking discharge cone 604.

[0044] Because the powder supply from multiple powder dispersing components 3 increases the exhaust volume within the wetting tower 4, the air-locking discharge cone 604 is required to cooperate with the dust collector 7 to return the unwetted or insufficiently wetted powder to the elevator 1. The dust collector 7 is placed directly above the air flow trough 101 of the elevator 1 to achieve rapid recirculation of the powder. The negative pressure ring silo 601 is fixedly connected to the lower cone of the wetting tower body 4 by welding, and the center position of the bottom end of the welding contact point is the air outlet. The discharge port 605 formed by the 1 / 2 drop of the corresponding surface is welded on the inclined surface of the sealing plate, and a hole plate is welded between the lower cone of the wetting cylinder and the discharge port 605. Several negative pressure silo inlets 603 are opened on the hole plate. The aperture of the negative pressure silo inlet 603 is about 200mm, and the hole spacing is about 100mm. At the same time, a wind-locking discharge cone 604 is designed downward on this horizontal plane. The lower cone diameter of the wind-locking discharge cone 604 is about 200mm smaller than the lower cone diameter of the wetting tower. In this way, air can be prevented from entering the negative pressure ring silo 601 during discharge and affecting the effect of screening powder.

[0045] According to a further optimization scheme, the central axis of the discharge port 605 is located on the side of the central axis of the negative pressure ring silo 601 away from the negative pressure silo outlet 602.

[0046] The space of the negative pressure ring silo 601 near the negative pressure silo outlet 602 is larger than the space of the negative pressure ring silo 601 away from the negative pressure silo outlet 602. In this embodiment, the negative pressure ring silo 601 is expanded by about 500mm on one side around the horizontal plane of the lower cone of the wetting tower body 4. In this way, the negative pressure values of the negative pressure silo inlet 603 on the negative pressure ring silo 601 can be close to the same, achieving a uniform and effective powder screening effect. An online moisture infrared detector is installed on the air-locking discharge cone 604 near the conveying direction of the first conveyor 8. The online moisture infrared detector is used to control the moisture content of the powder within an error of 0.3%. By quantitatively supplying powder and adjusting the water supply pressure, the moisture content of the wetted powder is guaranteed. Through the cooperation between the upper and lower material level meters 201 of the powder storage silo 2, the variable frequency rotary feeder motor, the water supply system 5, the rotary feeder indicator, and the dust removal power of the dust collector 7, an automated control system is realized. If online shutdown monitoring is installed for the operation status of multiple powder supply units at the same time, in production practice, wet powder production can be achieved by manual operation without using an online moisture infrared detector.

[0047] A further optimized solution is to form a powder awakening bin group with multiple powder awakening bins 11. The powder awakening bin 11 includes a cylinder and a discharge cone. The cylinder and the discharge cone are interconnected and fixedly connected.

[0048] The number and storage capacity of the powder awakening bins 11 are based on the requirement that the powder materials be fully aged, and then the capacity and number are determined according to the supply required for subsequent production to form a powder awakening bin group. The cylinder is used to provide an aging space for the powder materials, and the discharge cone is used to guide the aged powder materials out of the bin.

[0049] According to a further optimization scheme, the cylinder is a circular bin or a square bin, the discharge cone is a square cone, and one surface of the discharge cone is arranged in a straight line with the surface in contact with the cylinder in the vertical direction.

[0050] The cylinder is selected as a circular warehouse and / or a square warehouse according to the site planning and actual needs. The discharge cone at the bottom of the warehouse is mainly square. The cylinder in this embodiment is a square warehouse, and the discharge cone is a square discharge cone. One surface of the discharge cone is aligned with the surface perpendicular to the cylinder and is arranged in a vertical line. This helps to discharge the powder in the cylinder. A vibrator can be removed from any surface of the discharge cone. The vibrator can prevent material jamming in the discharge cone or the cylinder, thereby ensuring the normal operation of the equipment.
