Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of calcium silicate board production equipment, in particular to an automatic pulp flow equipment for calcium silicate board production. BACKGROUND

[0002] Calcium silicate board is a new generation of "green" building materials, which has excellent environmental protection function on the basis of excellent moisture-proof and fire-proof performance; calcium silicate board is a new type of building material formed by using silicon powder and calcium powder material as the main base material, natural wood fiber as the reinforcing material, and other auxiliary materials through pulp flow forming, and then curing at high temperature and high pressure.

[0003] During the forming process of calcium silicate board, a stirrer and a partition are installed in the pulp flow box of the board making machine. When the slurry reaches a certain liquid level in the pulp flow box, it naturally flows onto the felt through the horizontal and inclined pulp distribution plates to form a primary layer. The primary layer is forced to dehydrate through multiple vacuum boxes and is wound onto a forming cylinder. After reaching the required thickness, the wet blank is removed from the forming cylinder and processed into various shaped products through multiple processes.

[0004] Due to the high concentration of the mixture of plant fibers, siliceous materials (such as quartz powder, fly ash, and diatomite), and calcareous materials (such as lime and cement), and the relatively poor stirring capacity of the pulp flow box, and the lack of a mixed ash stabilizing device, it is easy to cause uneven concentration and unstable flow rate of the mixed slurry ejected from the weir, and the agglomeration of plant fibers leads to slurry flocculation, which in turn causes uneven thickness of the board, affecting the quality of the finished calcium silicate board.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 10 As shown, the automated headstock production equipment for calcium silicate board manufacturing of the present invention includes a headstock box 1. A headstock distribution pipe 2 is installed at one end of the headstock box 1, and an upper lip plate 131 and a lower lip plate 132 are installed at the other end of the headstock box 1. The upper lip plate 131 and the lower lip plate 132 form a headstock outlet. The upper lip plate 131 is movably installed on the headstock box 1 by bolts.

[0038] The headbox 1 is equipped with a first baffle 111 and a second baffle 121. The first baffle 111 and the second baffle 121 divide the headbox 1 into a stabilizing tank 11, an overflow tank 12 and a headbox 13. A leveling roller 15 is installed in the stabilizing tank 11 and the overflow tank 12, and an agitating roller 14 is installed in the headbox 13.

[0039] The lower end of the first baffle 111 is provided with a connecting slot 112. The slurry sent into the stabilizing tank 11 by the slurry distribution pipe 2 enters the overflow tank 12 through the connecting slot 112. The slurry in the overflow tank 12 overflows from the upper end of the second baffle 121 into the slurry flow tank 13. The slurry in the slurry flow tank 13 is discharged from the slurry outlet.

[0040] A baffle plate is installed in the slurry stabilization tank 11, and the slurry discharged from the slurry distribution pipe 2 impacts the surface of the baffle plate obliquely upward.

[0041] The upper end of the baffle plate is located below the liquid surface of the slurry in the slurry stabilization tank 11, the lower end of the baffle plate is located above the connecting groove 112, the slurry outlet 22 on the slurry distribution pipe 2 is located above the lower end of the baffle plate, and the upper end of the baffle plate is equipped with uniformly distributed metal teeth 34.

[0042] In the process of manufacturing calcium silicate board, the pulp flow equipment and the forming equipment are matched with each other, the pulp discharged from the pulp flow equipment is laid on the felt belt of the forming equipment, and the wet board blank is formed after dehydration;

[0043] Meanwhile, when the pulp flow equipment is used, the pulp stored in the high storage tank is sent into the pulp distribution pipe 2 in the headbox 1 through the feeding pipe 21, so that the pulp is sprayed from the pulp outlet 22 of the pulp distribution pipe 2 into the headbox 1, and after the pulp enters the headbox 1, the pulp is stirred by the stirring roller 14 and the pulp uniformizing roller 15, so that the pulp is mixed uniformly and the stratification of the pulp is avoided;

[0044] Meanwhile, since the pulp is discharged from the pulp flow port to the felt belt of the forming equipment after sequentially passing through the pulp stabilizing groove 11, the overflow groove 12 and the pulp flow groove 13, the pulp sent from the high storage tank at a high speed and with a large impact force will flow into the pulp stabilizing groove 11, so that the impact force and the fluctuation of the pulp are buffered and stabilized by the pulp stabilizing groove 11, and the flow rate of the pulp is stabilized;

[0045] Meanwhile, in the process of stirring, storing and conveying in the pipeline, and rapidly flowing into the headbox 1, the pulp is easy to generate bubbles or foams, the blocking plate is installed in the pulp stabilizing groove 11, so that the area where the pulp enters the pulp stabilizing groove 11 is relatively separated, when the pulp enters the headbox 1 from the pulp outlet 22 of the pulp distribution pipe 2, the pulp flows and impacts in an obliquely upward direction, so that the pulp is blocked and guided by the blocking plate, and the pulp flows upward, in this process, the bubbles and foams existing in the pulp gradually float upward and float on the surface of the pulp in the pulp stabilizing groove 11, at this time, the pulp stabilizing groove 11 and the overflow groove 12 are connected to each other through the connecting groove 112, so that after the impact force of the initial spraying of the pulp from which the bubbles and foams are separated is weakened, the pulp flows downward beyond the blocking plate, until the pulp enters the overflow groove 12 from the connecting groove 112, so that the bubbles or foams existing in the pulp do not cause the air cavity in the board blank or the unevenness of the surface of the board blank after the pulp is coated on the felt belt, and the quality of the formed board is affected;

[0046] Meanwhile, since the upper end of the blocking plate is provided with the metal teeth 34 which are uniformly distributed, when the pulp flows upward under the blocking and guiding of the blocking plate, the metal teeth 34 interfere with and destroy the bubbles or foams existing in the pulp, so that the bubbles or foams are reduced, and the pulp is prevented from overflowing from the headbox 1 due to the accumulation of too many bubbles or foams on the surface of the pulp stabilizing groove 11 after the pulp flow equipment is operated for a long time, so that the normal operation of the pulp flow equipment is affected and the factory environment and equipment are polluted;

[0047] Meanwhile, after the slurry enters the overflow tank 12, the liquid level of the slurry will gradually rise until the slurry enters the headbox 13 after passing through the second baffle 121, in the process, the slurry is further buffered and stabilized by the overflow tank 12, reducing the turbulent flow in the slurry, and avoiding fluctuations in the slurry, stabilizing the flow rate of the slurry, allowing the slurry to be evenly coated onto the felt belt, improving the quality of the calcium silicate plate blank;

[0048] Meanwhile, after the slurry from the upper end of the second baffle 121 overflows into the headbox 13, the slurry will be coated onto the felt belt from the headbox opening formed by the upper lip plate 131 and the lower lip plate 132, by adjusting the relative position of the upper lip plate 131 in the headbox 1, changing the distance between the upper lip plate 131 and the lower lip plate 132, so as to change the amount of coated slurry, adjust the thickness of the prepared plate blank.

[0049] As an embodiment of the present application, a through hole 33 is formed in the baffle plate, and a vibrator 312 is installed on the side of the baffle plate away from the pulp distribution pipe 2; the baffle plate is installed on the inner wall of the pulp stabilizing tank 11 through an elastic frame 311;

[0050] After the slurry is sprayed from the pulp outlet 22 on the pulp distribution pipe 2, it will impact on the baffle plate, as the baffle plate has a through hole 33, when the slurry contacts the baffle plate, the slurry is separated and homogenized by the through hole 33, improving the uniformity of the slurry, making the concentration of the slurry uniform, ensuring that the subsequent prepared calcium silicate plate blank has good quality, at the same time, as the baffle plate is installed with a vibrator 312 and the baffle plate is installed through an elastic frame 311, when the vibrator 312 starts to operate, it will drive the baffle plate to vibrate synchronously, and then the slurry contacting the surface of the baffle plate will be affected by the vibration, prompting the slurry near the baffle plate to be fully stirred and mixed, making the slurry mixed uniformly and impacting and dispersing the possible flocs or agglomerates in the slurry, ensuring that the slurry is uniform and the concentration is uniform, avoiding that the subsequent prepared calcium silicate plate has uneven thickness or poor quality.

[0051] As an embodiment of the present application, the baffle plate comprises a first layer plate 3 and a second layer plate 31, the first layer plate 3 is located between the second layer plate 31 and the pulp distribution pipe 2;

[0052] The through hole 33 is located on the first layer plate 3, and the vibrator 312 is located on the second layer plate 31;

[0053] The second layer plate 31 is installed with a vibration rod 32, and the vibration rod 32 is inserted into the through hole 33;

[0054] Through the limitation of the installation position between the first layer plate 3 and the second layer plate 31, the slurry sprayed in the cloth slurry pipe 2 will impact on the first layer plate 3, and part of the slurry will also pass through the through hole 33 on the first layer plate 3 to disperse and uniformly distribute the slurry, so that the concentration distribution of the slurry is uniform, and the uneven concentration of the slurry does not affect the subsequent calcium silicate board blank quality;

[0055] Meanwhile, the vibrator 312 is installed on the second layer plate 31, so that the second layer plate 31 and the vibration rod 32 on the second layer plate 31 vibrate, improving the vibration mixing effect of the slurry, making the concentration of the slurry uniform, and through the vibration rod 32 inserted into the through hole 33, the slurry near the through hole 33 is vibrated, mixed and stirred, promoting the mixing and uniformity of the slurry, improving the uniformity of the slurry concentration, and through vibration, the bubbles or foams existing in the slurry are relatively separated, the bubbles or foams are floated to the surface, and the flocs existing in the slurry are vibrated and dispersed, so that the concentration distribution of the slurry is uniform;

[0056] Meanwhile, due to the gap between the first layer plate 3 and the second layer plate 31, after the slurry impacts on the first layer plate 3, the slurry passing through the through hole 33 on the first layer plate 3 will enter between the first layer plate 3 and the second layer plate 31, so as to be stirred and mixed after contacting the vibration rod 32, further promoting the mixing and uniformity of the slurry, so that the concentration of the slurry is uniform.

[0057] As an embodiment of the present application, the second layer plate 31 and the vertical plane form an angle, and the distance between the second layer plate 31 and the first layer plate 3 gradually increases from bottom to top.

[0058] After the slurry passes through the through hole 33 and enters between the first layer plate 3 and the second layer plate 31, the slurry will contact the inclined second layer plate 31, so that the part of the slurry is guided and drained by the second layer plate 31, so that the part of the slurry also flows upward, avoiding the downward flow of the slurry, the bubbles or foams or flocs remaining in the slurry, causing the bubbles, foams and the like to enter the headbox 1 and the subsequent board blank, affecting the board blank quality of the calcium silicate board.

[0059] As an embodiment of the present application, the vibration rod 32 is elastic, the diameter of the vibration rod 32 is smaller than the diameter of the through hole 33, the end of the vibration rod 32 is provided with a contact arc plate 321, and the contact arc plate 321 and the inner wall of the through hole 33 are in contact with each other.

[0060] Due to the fibers in the slurry, during the process of the slurry passing through the through hole 33, the long fibers in the slurry are easy to hang on the edge of the through hole 33, affecting the normal use of the through hole 33 or causing the through hole 33 to be blocked, and at the same time, due to the vibration rod 32 being inserted into the through hole 33, the contact arc plate 321 is installed at the end of the vibration rod 32, so that when the vibration rod 32 vibrates, the contact arc plate 321 is driven to stir and scrape the inner wall and edge of the through hole 33, so that the long fibers attached to the edge of the through hole 33 are cleaned down, and the fibers and fiber flocs are re-dispersed and mixed under the action of slurry impact and vibration, improving the uniformity of the slurry.

[0061] As an embodiment of the present application, the contact arc plate 321 is rotatably installed on the vibration rod 32.

[0062] Due to the contact arc plate 321 being rotatably installed on the vibration rod 32, the vibration of the vibration rod 32 will cause the contact arc plate 321 to continuously contact different positions on the through hole 33, cooperate with the impact of the slurry and the force change when contacting the through hole 33, promote the contact arc plate 321 to rotate relative to the vibration rod 32, and enable the contact arc plate 321 to contact and clean each place on the circumference of the through hole 33, ensuring that the slurry can pass through the through hole 33 smoothly, avoiding the through hole 33 from being blocked, and at the same time, the structure and volume of the contact arc plate 321 can be simplified, avoiding the contact arc plate 321 being relatively large and affecting the passing of the slurry from the through hole 33.

[0063] As an embodiment of the present application, the second baffle 121 is provided with guide vanes 122, the guide vanes 122 are arrayed on the second baffle 121, the guide vanes 122 are installed on the mounting plate 123, and the mounting plate 123 is fixed on the side wall of the headbox 1 by bolts.

[0064] The slurry entering the overflow tank 12 will overflow from the upper end of the second baffle 121 and enter the flow tank 13, by installing the guide vanes 122 on the upper end of the second baffle 121, the slurry will be guided and restricted by the guide vanes 122 during the overflow process, preventing the possible transverse flow trend in the flow direction during the slurry flow, ensuring that the slurry flowing into the flow tank 13 has stable flow rate and flows stably, reducing the fluctuation of the slurry flow or the instability of the flow rate, ensuring the uniformity of the slurry concentration, and at the same time, due to the guide vanes 122 being installed on the second baffle 121 and arrayed, by adjusting the gap between the guide vanes 122, the possible flocs in the slurry overflowing can be blocked, avoiding the flocs entering the flow tank 13 and finally being laid on the felt belt, so that the existing flocs are blocked and re-dispersed by multiple interception and dispersion impact, ensuring the uniformity of the slurry and the uniformity of the concentration, and improving the quality of the calcium silicate board blank.

[0065] As an embodiment of the present application, the flow slurry device is used in cooperation with a forming device, and a felt belt for carrying slurry is installed on the forming device;

[0066] The lower lip plate 132 is provided with an elastic sheet 133 between the lower lip plate 132 and the felt belt, and the elastic sheet 133 is obliquely installed, and the oblique direction of the elastic sheet 133 is towards the moving direction of the felt belt;

[0067] After the slurry is discharged from the flow slurry port, the slurry falls on the moving felt belt of the forming device, and the slurry is laid on the felt belt, and there is a gap between the lower lip plate 132 and the felt belt, and the gap is blocked by the elastic sheet 133, so that the slurry laid at the flow slurry port is smoothly and fully laid on the felt belt, and the situation that the slurry flows reversely or overflows from the felt belt is avoided in the case that the slurry is relatively thin or the speed of the felt belt is relatively slow, and the quality of the calcium silicate board blank is ensured to be good.

[0068] The specific working process is as follows:

[0069] When the flow slurry device is used, the slurry stored in the high-position storage tank is sent into the distribution pipe 2 in the flow slurry box 1 through the feeding pipe 21, so that the slurry is sprayed from the slurry outlet 22 of the distribution pipe 2 into the flow slurry box 1;

[0070] The slurry sequentially passes through the slurry stabilizing groove 11, the overflow groove 12 and the flow slurry groove 13, and is then discharged from the flow slurry port to the felt belt of the forming device;

[0071] The blocking plate is installed in the slurry stabilizing groove 11, so that the area where the slurry enters the slurry stabilizing groove 11 is relatively separated, and when the slurry enters the flow slurry box 1 from the slurry outlet 22 of the distribution pipe 2, the slurry flows and impacts in an obliquely upward direction, so that the slurry is blocked and guided by the blocking plate, and the slurry flows upward, and in this process, the bubbles and foams existing in the slurry gradually float upward and float on the surface of the slurry in the slurry stabilizing groove 11, and at this time, after the impact force of the slurry in the initial spraying is weakened, the slurry separated from the bubbles and foams flows downward through the blocking plate and enters the overflow groove 12 from the connecting groove 112;

[0072] Since the upper end of the blocking plate is provided with uniformly distributed metal teeth 34, when the slurry flows upward under the blocking and guiding of the blocking plate, the metal teeth 34 interfere with and destroy the bubbles or foams existing in the slurry, and the bubbles or foams are reduced;

[0073] After the slurry enters the overflow groove 12, the liquid level of the slurry gradually rises, and the slurry enters the flow slurry groove 13 after passing through the second blocking plate 121;

[0074] After the slurry overflows from the upper end of the second baffle 121 into the headbox 13, the slurry will be coated onto the felt belt from the headbox opening formed by the upper lip plate 131 and the lower lip plate 132. By adjusting the relative position of the upper lip plate 131 in the headbox 1, changing the distance between the upper lip plate 131 and the lower lip plate 132, and changing the amount of slurry coated;

[0075] After the slurry is sprayed from the slurry outlet 22 on the headbox pipe 2, the slurry is separated and homogenized by the through hole 33 after the slurry contacts the baffle. At the same time, since the vibrator 312 is installed on the baffle and the baffle is installed by the elastic frame 311, when the vibrator 312 starts to operate, it will drive the baffle to vibrate synchronously, so that the slurry on the surface of the baffle will be affected by the vibration, and the slurry near the baffle will be fully stirred and mixed;

[0076] By limiting the installation position between the first layer plate 3 and the second layer plate 31, the slurry sprayed from the headbox pipe 2 will impact on the first layer plate 3, and part of the slurry will also pass through the through hole 33 on the first layer plate 3 to disperse and uniform the slurry;

[0077] At the same time, the vibrator 312 is installed on the second layer plate 31, so that the second layer plate 31 and the vibration rod 32 on the second layer plate 31 vibrate, improving the vibration mixing effect of the slurry. At the same time, the vibration rod 32 inserted into the through hole 33 vibrates the slurry near the through hole 33, and the vibration also promotes the relative separation of the bubbles or foams existing in the slurry, promotes the bubbles or foams to float to the surface, and also disperses the possible flocs by vibration;

[0078] At the same time, since there is a gap between the first layer plate 3 and the second layer plate 31, after the slurry impacts on the first layer plate 3, the slurry passing through the through hole 33 on the first layer plate 3 will enter between the first layer plate 3 and the second layer plate 31, so as to be stirred and mixed after contacting the vibration rod 32, further promoting the mixing and uniformity of the slurry;

[0079] After the slurry passes through the through hole 33 and enters between the first layer plate 3 and the second layer plate 31, the slurry will contact the inclined second layer plate 31, so that this part of the slurry is guided and drained by the second layer plate 31, so that this part of the slurry also flows upward, avoiding the downward flow of the slurry, the bubbles or foams or flocs remaining in the slurry, causing bubbles, foams, etc. to enter the headbox 1 and the subsequent slabs;

[0080] Meanwhile, since the vibration rod 32 is inserted into the through hole 33, the contact arc plate 321 is installed at the end of the vibration rod 32, so that when the vibration rod 32 vibrates, the contact arc plate 321 is driven to agitate and scratch the inner wall and edge of the through hole 33, so that the long fibers attached to the edge of the through hole 33 are cleaned off, and the fibers and fiber flocs are re-dispersed and mixed under the action of slurry impact and vibration.

[0081] Since the contact arc plate 321 is rotatably installed on the vibration rod 32, with the vibration of the vibration rod 32, the contact arc plate 321 will continuously contact different positions on the through hole 33, cooperate with the impact of the slurry and the force change when contacting the through hole 33, promote the rotation of the contact arc plate 321 relative to the vibration rod 32, so that the contact arc plate 321 can contact and clean each part of the through hole 33, and at the same time, the structure and volume of the contact arc plate 321 can be simplified, avoiding the relatively large contact arc plate 321 affecting the passing of the slurry from the through hole 33.

[0082] The guide vane 122 is installed at the upper end of the second baffle 121, so that the slurry will be guided and constrained by the guide vane 122 during overflow, and the transverse flow trend in the flow direction during slurry flow can be prevented, and at the same time, since the guide vane 122 is installed on the second baffle 121 and arranged in an array, by adjusting the gap between the guide vanes 122, the flocs that may exist in the slurry overflowing can be blocked.

[0083] After the slurry is discharged from the flow gap, it will fall on the moving felt belt on the forming equipment, so that the slurry is laid on the felt belt, and there will be a gap between the lower lip plate 132 and the felt belt, and the gap between the two is sealed by the elastic sheet 133, so as to ensure that the slurry laid at the flow gap is smoothly and fully laid on the felt belt.

[0084] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
