Description

Technical Field

[0001] The present invention belongs to the technical field of wet powder making for building ceramics, and particularly relates to an efficient wet production equipment for wet powder making of building ceramics. Background Art

[0002] The dry powder making process is a powder making technology in the production of building ceramics. Its process summary is: raw material crushing, batching, fine grinding, sieving, over-wetting granulation, screening, aging, dry pressing forming, and sintering.

[0003] Currently, in the building ceramic industry in our country, there are generally two powder making processes. One is the dry powder making process, and the other is the wet powder making process. Now, the wet powder making process is widely used in the industry. Due to problems such as high energy consumption, high pollution, and high emissions in the wet powder making process, as well as the practical problem of continuously burning coal in the powder making link and the urgent need for technological upgrading of the powder making process. In the building ceramic industry, the dry powder making process has the advantages of low energy consumption, low emissions, and no pollution compared with the wet powder making process. However, it has technical bottlenecks in terms of unstable output and quality in the over-wetting granulation process of dry powder making. In dry powder making production, there is an easy phenomenon of large cracks and breakages in products, resulting in the inability to widely promote the dry powder making process technology in the building ceramic industry.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. Embodiment

[0021] Refer to Figures 1 to 10As shown in the figure, this embodiment provides an efficient wetting production equipment for building ceramic wetting and powder making, including a hoist 1. The outlet of the hoist 1 is communicated with a powder storage bin 2. A number of powder supply and dispersion components 3 are communicated at the bottom of the powder storage bin 2. The number of powder supply and dispersion components 3 is communicated with the top of a wetting tower body 4. The fine water mist component 320 built in the wetting tower body 4 is communicated with a water supply system 5. A constant pressure dust removal chamber 6 is fixedly connected to the bottom of the wetting tower body 4. The constant pressure dust removal chamber 6 is communicated with a dust collector 7 through a negative pressure pipe. The discharge port of the dust collector 7 is communicated with the air chute 101 of the hoist 1. A lock air discharging cone 604 is installed at the bottom of the wetting tower body 4. A first conveyor 8 is arranged at the discharge port of the lock air discharging cone 604. The output end of the first conveyor 8 is connected to a drum screen device 9. A second conveyor 10 is arranged at the output port of the drum screen device 9. The output end of the second conveyor 10 is communicated with a number of powder awakening bins 11. A third conveyor 12 is arranged at the bottom of the powder awakening bin 11. The output end of the third conveyor 12 is cooperatively connected with a fourth conveyor 13.

[0022] The powder material enters the powder storage bin 2 through the elevator 1. The discharge port of the elevator 1 is hermetically connected directly to the powder storage bin 2. The lifting capacity of the elevator 1 is designed to exceed 20% of the wetting output of the wetting tower body 4 in this embodiment. Upper and lower level gauges 201 are installed on the circumferential 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 powder production capacity of the wetting tower body 4. A high-density PE anti-sticking plate can be optionally pasted on the inner surface of the powder storage bin 2. The powder storage bin 2 is supported by four support columns. A number of powder supply and dispersion components 3 connected to the bottom of the powder storage bin 2 can evenly disperse the powder material into the wetting tower body 4. In this embodiment, the number of powder supply and dispersion components 3 is preferably 3, 4, 5, or 6. When facing a production line with a large required powder production volume, a large amount of powder material can be evenly dispersed by increasing the powder supply and dispersion components 3. When the required powder production volume of the production line is small, the powder supply and dispersion components 3 can be reduced for adaptation. Similarly, when facing different powder production volume requirements, the water volume supplied by the water supply system 5 is also adjusted correspondingly (increase the water supply volume for a large required powder production volume, and reduce the water supply volume for a small required powder production volume). Before the tap water enters the water supply system 5, it needs to be preheated to 40°C to 60°C by the hot water boiler 501, and the water temperature is increased to 50°C in this embodiment. Specifically, five production levels are formulated according to the system powder production volume, and the hourly wetting powder production volume is divided into: 20 tons, 30 tons, 40 tons, 50 tons, and 60 tons, and the corresponding diameters of the wetting tower body 4 are: 3m, 4m, 4.5m, 5m, and 5.5m. The constant pressure dust removal chamber 6 at the bottom of the wetting tower body 4 can accurately separate the powder material that does not meet the wetting standard, and make it re-enter the elevator 1 through the dust collector 7 to form a powder production closed loop, so as to achieve more standardized, automated, and intelligent production on the premise of reducing manual intervention. The powder material that meets the wetting standard is sent to the roller screen device 9 through the first conveyor 8 for screening of the powder particle size. The second conveyor 10 sends the powder material with qualified size to the proofing bin 11. In this embodiment, the powder material is sent to the proofing bin 11 for proofing for 24 hours. If tap water at normal temperature (10°C to 25°C) is used, it needs to be proofed for 36 hours to 48 hours. During the proofing process, the moisture in the powder material realizes further uniform distribution of moisture in the powder material through natural penetration and diffusion, reducing or avoiding problems such as uneven shrinkage, cracking, or deformation of the powder material caused by uneven moisture distribution in the subsequent forming process. In this way, the physical and chemical properties of the powder material can be improved before the forming process, the 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.One third conveyor 12 is arranged at the bottom of each dough proofing bin 11. The powdered materials after dough proofing fall onto the third conveyor 12 through the outlet at the bottom of the dough proofing bin 11. Then, the third conveyor 12 uniformly introduces the powdered materials onto the fourth conveyor 13 for subsequent forming processes. The main body of the dough proofing bin 11 is square, and one of the bottom surfaces extends vertically downward from one surface of the main body. The other three surfaces can be set as inclined surfaces according to the required powder output to form the outlet of the dough proofing bin 11. By adjusting the number of powder supply dispersion components 3, the water supply volume of the water supply system 5, the dust removal power of the dust collector 7, and the diameter of the wetting tower body 4, a feasible solution can be formulated for production lines with different powder production requirements. This pre-solves and paves the way for the problems of different demand quantities encountered in the subsequent promotion of dry wet powder making technology.

[0023] For a further optimized solution, the powder supply dispersion component 3 includes a cloth feeding assembly. The cloth feeding assembly is communicated with the powder storage bin 2. The bottom of the cloth feeding assembly is communicated with a cylindrical diffuser. The cylindrical diffuser is communicated with the wetting top plate 401 of the wetting tower body 4. The output end of the blower 303 is communicated with an air delivery pipe 304. The air delivery pipe 304 is divided into a horizontal section and a vertical section. The horizontal section horizontally extends into the cylindrical diffuser and extends to the center of the cylindrical diffuser. One end of the vertical section is communicated with the horizontal section, and the other end of the vertical section extends downward below the wetting top plate 401. A plurality of punching plates 310 are fixedly connected to the bottom ends of a plurality of vertical sections together. The vertical section is successively provided with a first air outlet hole group 3041, a second air outlet hole group 3042, and a third air outlet hole group 3044 from top to bottom. A plurality of air guiding inclined pipes 3043 are arranged between the second air outlet hole group 3042 and the third air outlet hole group 3044. The plurality of air guiding inclined pipes 3043 are communicated with the vertical section.

[0024] The fabric component is composed of a conical hopper 301, a feeder 302, and a conical cylinder 305. The top of the conical hopper 301 is fixedly connected to the powder storage bin 2. The bottom of the conical hopper 301 is adaptively connected to the feeder 302 with a gap. The top of the conical cylinder 305 is connected and detachably connected to the discharge port of the feeder 302. The bottom of the conical cylinder 305 is connected and detachably or fixedly connected to the top of the cylindrical diffuser. Among them, the feeder 302 is preferably a rotary feeder. The bottom opening of the conical cylinder 305 is reduced by about 20% compared to the top opening. The conical cylinder 305 is preferably a square conical cylinder 305. In this way, when the feeder 302 is rotating and feeding materials, the square conical cylinder 305 can cause damping of the powder at the reduced opening to avoid rapid falling, so as to form a stable and continuous powder supply. The bottom of the cylindrical diffuser is connected to the wetting top plate 401 at the top of the wetting tower body 4, facilitating further dispersion and wetting of the powder in a timely manner after dispersion. The edge of the perforated plate 310 is about 500 mm away from the inner wall of the wetting tower body 4, and both the punching diameter and the hole spacing are about 20 mm. When there are several air ducts 304, a shared blower 303 can be used for the branch ducts, or several blowers 303 can be equipped according to the actual situation to correspond one by one with several air ducts 304. Among them, the blower 303 is preferably installed on 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 the rapid dispersion of the material after the rotary feeder drops the material in the horizontal section. The length of the vertical section extending downward into the wetting tower body 4 is about 500 mm, and the bottom end of the vertical section is closed. The positions of the first air outlet hole group 3041, the second air outlet hole group 3042, and the air guiding inclined tube 3043 on the vertical section are at the same distance from the connection of the air duct 304. The opening diameter and the diameter of the air duct 304 are both about 10 mm. A circular hole group with a diameter of 10 mm is drilled at the bottom of the vertical section in the wetting tower body 4, and the number of rows in the vertical direction of the hole group is 2 - 4 rows. This can achieve a good powder dispersion effect and provide better conditions for the subsequent wetting of the powder.

[0025] In a further optimized solution, the horizontal height of the bottom ends of several air guiding inclined tubes 3043 is flush with the top of the opening of the uppermost part of the third air outlet hole group 3044.

[0026] The air guiding inclined tube 3043 is arranged obliquely downward. The holes opened on the vertical section can fully disperse the nearby powder. The powder farther away from the vertical section will be further dispersed by the wind led out by the air guiding inclined tube 3043. At the same time, it is also beneficial for the powder to be blown down when passing through the perforated plate 310, so as to avoid the accumulation of materials on the perforated plate 310 farther away from the vertical section.

[0027] In a further optimized solution, the air guiding inclined tubes 3043 are distributed in an umbrella shape.

[0028] The air guide inclined pipe 3043 is distributed in an umbrella shape, which can also disperse and blow down the powder within a relatively far circumferential range of each vertical section. The included angle between the air guide inclined pipe 3043 and the air delivery pipe 304 of the vertical section is 45° - 60°, which can achieve the effect of powder dissipation in the largest range and prevent powder accumulation.

[0029] In a further optimized solution, a support pull rod 3205 is fixedly connected to the bottom of the punching plate 310. A number of pull rings are fixedly connected to the support pull rod 3205, and the number of pull rings is vertically distributed on the support pull rod 3205. 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 detachable parts, 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.

[0030] The top of the support pull rod 3205 is fixedly connected to the bottom of the punching plate 310. The pull rings on the support pull rod 3205 are installed at intervals up and down. The number of pull rings is adjusted according to the amount of powder to be wetted and milled. In this embodiment, two pull rings are set. Both the upper fine water mist assembly 3201 and the lower fine water mist assembly 3203 include a number of water distribution branch pipes. Within the distance from the 200 mm position at the top end to the 300 mm position at the end of the water distribution branch pipe, spray nozzle seats are welded at intervals of about 200 mm. At each installation point, two spray nozzle seats are installed at an included angle of 120 degrees in the downward direction of the cross-section of the water distribution pipe. Each spray nozzle seat can be installed with one spray nozzle or 2 - 3 spray nozzles according to the water volume requirement. The number of spray nozzles is calculated according to the single-nozzle water spray volume and the water content of about 9% in the wetted and milled powder. At the same time, the number of water distribution branch pipes is calculated according to the diameter of the wetting tower. The water distribution branch pipes are respectively hung on the upper pull ring 3206 and the lower pull ring 3207 through the hooks at the top ends. The water distribution branch pipes form an included angle of about 25°C with the tower wall upward in the wetting tower, realizing a double-layer umbrella-shaped spray unit. Such an angle can quickly make the powder slide down when it falls on the water distribution branch pipes, preventing the phenomenon of powder accumulation. The bottom ends of the water distribution branch pipes extend out of the tower body through the openings of the wetting tower body 4 and are detachably connected to the fixing parts fixed on the tower body, and the fixing parts are used to fix the water distribution branch pipes.

[0031] In a further optimized solution, the water supply system 5 includes a connecting hose 3202. Both the upper fine water mist assembly 3201 and the lower fine water mist assembly 3203 are 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.

[0032] The water distribution branch pipe is connected to the water supply loop pipe 3204 through a high-pressure resistant hose 3202 and a high-pressure resistant valve, so that subsequent removal and maintenance of a single water distribution branch pipe can be realized. Compared with workers entering the wetting tower for maintenance, the maintenance time and cost are saved. The water supply system 5 provides a high-pressure water source with a particle size less than 0.2 mm for the water supply pipe.

[0033] In a further optimized solution, the constant-pressure dust removal chamber 6 includes a negative-pressure ring bin 601. A material discharge port 605 is provided in the middle of the negative-pressure ring bin 601. The bottom of the outer ring surface of the wetting tower body 4 is adapted to the material discharge port 605. A negative-pressure bin outlet 602 is provided on the outer ring surface of the negative-pressure ring bin 601. The negative-pressure bin outlet 602 is detachably connected to a negative-pressure pipe. A wind-lock material discharge cone 604 is fixedly connected to the bottom of the outer ring surface of the negative-pressure ring bin 601. The first conveyor 8 is located below the bottom outlet of the wind-lock material discharge cone 604.

[0034] Due to the increase in the exhaust gas volume in the wetting tower body 4 caused by powder supply from multiple powder supply and dispersion components 3, the wind-lock material discharge cone 604 and the dust collector 7 need to cooperate to re-place the powders that are not wetted or have insufficient wetting degree into the elevator 1. The dust collector 7 is directly placed above the air chute 101 of the elevator 1 to achieve rapid powder reflux. The negative-pressure ring bin 601 is fixedly connected to the lower conical opening of the wetting tower body 4 by welding. Taking the center position at the bottom end of the welding contact point as the air outlet, a sealing plate is welded on the inclined surface of the material discharge port 605 formed at the position where the corresponding surface descends by 1 / 2. A perforated plate is welded between the lower conical opening of the wetting cylinder and the material discharge port 605. A number of negative-pressure bin inlets 603 are provided on the perforated plate. The aperture of the negative-pressure bin inlet 603 is about 200 mm, and the hole pitch is about 100 mm. At the same time, a wind-lock material discharge cone 604 is designed downward at this horizontal plane. The lower conical diameter of the wind-lock material discharge cone 604 is about 200 mm smaller than the lower conical diameter of the wetting tower, so that air can be prevented from entering the negative-pressure ring bin 601 during material falling, which affects the effect of screening powders.

[0035] In a further optimized solution, the central axis of the material discharge port 605 is located on the side of the central axis of the negative-pressure ring bin 601 away from the negative-pressure bin outlet 602.

[0036] The space of the negative pressure annular bin 601 near the outlet 602 of the negative pressure bin is larger than that of the negative pressure annular bin 601 far from the outlet 602 of the negative pressure bin. In this embodiment, the negative pressure annular bin 601 expands about 500 mm unilaterally around the horizontal plane of the lower conical opening of the wetting tower body 4. In this way, the negative pressure values at the negative pressure bin inlets 603 on the negative pressure annular bin 601 can be made approximately the same, achieving a uniform and effective screening effect for the powder materials. An on-line moisture infrared detector is installed at a position on the air-lock discharging cone 604 close to the conveying direction of the first conveyor 8. The on-line moisture infrared detector is used to control the moisture content error of the powder materials within 0.3%. By quantitatively supplying powder and adjusting the water supply pressure, the moisture content of the wetted powder materials is ensured. Through the cooperation among the upper and lower level gauges 201 of the powder storage bin 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 automatic control system is achieved. If the working conditions of multiple powder supply units are additionally monitored online during shutdown, in production practice, wet powder production can also be achieved through manual operation without using the on-line moisture infrared detector.

[0037] For a further optimized solution, a waking bin group is composed of multiple waking bins 11. The waking bin 11 includes a cylinder body and a discharging cone. The cylinder body and the discharging cone are communicated and fixedly connected.

[0038] The number and storage capacity of the waking bins 11 are determined with reference to ensuring that the powder materials are fully aged, and then the capacity and number are formulated according to the supply required for subsequent production to form a waking bin group. The cylinder body is used to provide an aging space for the powder materials, and the discharging cone is used to discharge the aged powder materials outside the bin.

[0039] For a further optimized solution, the cylinder body is a circular bin or a square bin, and the discharging cone is a square cone. One surface of the discharging cone in contact with the vertical direction of the cylinder body is arranged in a straight line.

[0040] The cylinder body is selected as a circular bin and / or a square bin according to the site planning and actual requirements. The discharging cone at the bottom of the bin body is mainly square. In this embodiment, the cylinder body is a square bin, and the discharging cone is a square discharging cone. One surface of the discharging cone in the same direction as the vertical direction of the cylinder body is arranged vertically in a straight line. This helps the powder materials in the cylinder body to be discharged. A vibrator is detachably installed on any surface of the discharging cone. The vibrator can prevent material jamming in the discharging cone or the cylinder body, ensuring the normal operation of the equipment.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0042] The embodiments described above are only for describing the preferred mode of the present invention, rather than limiting the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
