[0002] Pulping refers to the process of mixing water and solid raw materials (such as clay, cement, etc.) into slurry. The specific process is to pre-configure the ratio of water and solid raw materials, and then send a certain amount of water and solid raw materials into the pulping system for pulping. This results in the pulping system only being able to configure slurry with one water-to-solid ratio at the same time. When slurry with other water-to-solid ratios needs to be configured, the relevant equipment needs to be cleaned and reconfigured, which is time-consuming and labor-intensive, and has low work efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Combine the following Figures 1 to 7 A pulping system according to an embodiment of the present invention is described.

[0041] like Figure 1 and Figure 2 As shown, the pulping system includes a monitoring room 100 , a silo 200 , a pulping machine 300 , a pulp storage barrel 400 , an additive adding device 500 , a water tank 600 and a recovery barrel 700 .

[0042] The monitoring room 100 is used to control the operation of the silo 200, the pulping machine 300, the pulp storage barrel 400, the admixture adding device 500, the water tank 600 and the recovery barrel 700 and monitor the relevant parameters of the silo 200, the pulping machine 300, the pulp storage barrel 400, the admixture adding device 500, the water tank 600 and the recovery barrel 700, including but not limited to monitoring the raw material content in the silo 200, the content of the initial slurry in the pulping machine 300 and the pulp storage barrel 400, the amount of admixture added by the admixture adding device 500, the water level of the water tank 600, the content of the slurry recovered in the recovery barrel 700, and the grouting pressure, the slurry flow rate, the slurry density, the return slurry flow rate, the density, etc. The monitoring room 100 is also provided with power failure alarm and overload alarm functions, etc. When the pulping system fails, it can send an alarm signal in time and stop the pulping system operation.

[0043] Under the control of the monitoring room 100 , the silo 200 delivers a predetermined amount of solid raw material to the pulper 300 through the first feeding pipe 210 , and the predetermined amount of raw material and a predetermined amount of water are fully stirred and pulped in the pulper 300 to form an initial water-to-solid ratio slurry.

[0044] Under the control of the monitoring room 100 , the pulping machine 300 delivers a certain amount of initial water-to-solid ratio slurry through the second feeding pipe 220 to the slurry storage barrel 400 for storage for subsequent use.

[0045] The slurry storage barrel 400 is connected to a plurality of additive adding devices 500 through multiple independent third feeding pipes 230, so that the slurry in the slurry storage barrel 400 can be simultaneously transported to the plurality of additive adding devices 500. The additive adding device 500 is used to add the required reagents to the slurry. At the same time, each additive adding device 500 is connected to the water tank 600 through an independent water pipe. When the water-to-material ratio of the slurry in one of the additive adding devices 500 needs to be changed, the water tank 600 injects a predetermined amount of water into the corresponding additive adding device 500 under the control of the monitoring room 100 to adjust the slurry. In this embodiment, the slurry storage barrel 400 is connected to four additive adding devices 500 through four independent third feeding pipes 230. The number of additive adding devices 500 can be adjusted according to actual needs, and is not specifically limited in this application. The number of third feeding pipes 230 is consistent with the number of additive adding devices 500.

[0046] Each additive adding device 500 delivers the adjusted slurry to the corresponding external device for use through the corresponding fourth feeding pipe 240 under the control of the monitoring room 100. At the same time, each additive adding device 500 delivers the excess slurry to the recovery barrel 700 for recovery through the fifth feeding pipe 250 under the control of the monitoring room 100.

[0047] Under the control of the monitoring room 100, the recovery barrel 700 transports the recovered slurry through the sixth feeding pipe 260 to the pulping machine 300 for recycling, without discarding the slurry.

[0048] In some specific embodiments of the present invention, the silo 200, the slurry storage barrel 400, the additive adding device 500 and the recovery barrel 700 are all provided with corresponding stirring mechanisms (not shown in the figure) to prevent discharge blockage or uneven slurry stirring.

[0049] In some specific embodiments of the present invention, a discharge valve (not shown in the figure) is provided at the bottom of the silo 200, and the discharge valve is electrically connected to the monitoring room 100. The discharge valve is opened under the control of the monitoring room 100 to feed the raw materials in the silo 200 into the pulping machine 300.

[0050] In some specific embodiments of the present invention, a liquid level sensor is provided in the pulp storage barrel 400 for detecting the height of the slurry in the pulp storage barrel 400; the liquid level sensor is electrically connected to the monitoring chamber 100 to feedback the height of the slurry in the pulp storage barrel 400; when the height of the slurry in the pulp storage barrel 400 is lower than the lower limit value, the monitoring chamber 100 controls the pulping machine 300 to make pulp and transport the slurry to the pulp storage barrel 400; when the height of the slurry in the pulp storage barrel 400 is higher than the upper limit value, the monitoring chamber 100 controls the pulping machine 300 to stop making pulp; such a configuration can reduce power loss to a certain extent.

[0051] In some specific embodiments of the present invention, liquid level sensors are provided in the additive adding device 500 and the recovery barrel 700, which are used to detect the height of the slurry in the additive adding device 500 and the recovery barrel 700, respectively; the liquid level sensor is electrically connected to the monitoring room 100 to feedback the height of the slurry in the additive adding device 500 and the recovery barrel 700.

[0052] In some specific embodiments of the present invention, the water tank 600 is provided with a water outlet valve (not shown in the figure) at the water pipe connection, and the water outlet valve is electrically connected to the monitoring room 100. The water outlet valve is opened under the control of the monitoring room 100 to allow the water in the water tank 600 to enter the additive adding device 500.

[0053] like Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the third feeding pipeline 230, the fifth feeding pipeline 250 and the sixth feeding pipeline 260 are all provided with a pressure pump 270, and the monitoring room 100 controls the pressure pump 270 to work to speed up the slurry delivery speed.

[0054] like Figure 1 and Figure 2As shown, in some specific embodiments of the present invention, the second feeding pipe 220, the third feeding pipe 230, the fourth feeding pipe 240, the fifth feeding pipe 250 and the sixth feeding pipe 260 are all provided with a one-way valve 334, and the monitoring room 100 controls the one-way valve 334 to open for slurry transportation.

[0055] like Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the fifth feeding pipeline 250 can be configured as a main pipeline and multiple branch pipelines; one ends of the multiple branch pipelines are simultaneously connected to the main pipeline to form a passage, and the other ends of the multiple branch pipelines are each connected to an additive adding device 500, and a one-way valve 334 is provided on each branch pipeline.

[0056] like Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, the pulping machine 300 includes a material barrel 310, a stirring device 320 and a conveying device 330. The material barrel 310 is used to hold water and solid raw materials. After the water and the solid raw materials are mixed in the material barrel 310 to form a mixed material, they enter the stirring device 320 for stirring. When the mixed material in the material barrel 310 has not been fully stirred, the mixed material stirred by the stirring device 320 is sent to the material barrel 310 through the conveying device 330 to be remixed with the unstirred mixed material and then enter the stirring device 320 for stirring again, and the cycle is repeated until the mixed material is fully stirred to finally form an initial water-to-material ratio slurry. When the mixed material in the material barrel 310 is fully stirred, the pulping machine 300, under the control of the monitoring room 100, transports a certain amount of the initial water-to-material ratio slurry to the slurry storage barrel 400 through the conveying device 330 and the second feeding pipeline 220.

[0057] like Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, a filter screen 311 is provided at the upper opening of the material barrel 310. The filter screen 311 has a grid-like structure, which can not only screen out solid raw materials that do not meet the specified size, but also to a certain extent prevent the material stirred by the stirring device 320 from splashing when it re-enters the material barrel 310. It should be noted that the size and shape of the grid on the filter screen 311 can be selected according to actual needs and are not specifically limited in this application.

[0058] like Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, the upper portion of the material barrel 310 is a cylindrical structure, the lower portion is an inverted truncated cone structure, the upper portion and the lower portion both have a hollow cavity, and the upper and lower cavities are connected. The filter screen 311 is horizontally arranged at the upper end opening of the upper cavity of the material barrel 310.

[0059] like Figure 5 As shown, in some specific embodiments of the present invention, a plurality of separation rods 313 are provided at the position near the discharge port of the lower cavity of the material barrel 310. When feeding, the falling solid raw materials and water will touch the separation rods 313 and pre-mix, so that the solid raw materials and water form a slurry before entering the stirring device 320, so that the stirring device 320 can work smoothly. A plurality of separation rods 313 form a separation frame, and a plurality of separation rods 313 can be provided in one piece, which simplifies the installation of the separation rods 313 and the material barrel 310 and reduces the manufacturing difficulty. It should be noted that the plurality of separation rods 313 include horizontal rods in a horizontal state and vertical rods in an upright state, which can stir the mixed material in all directions from the top and bottom directions and the horizontal direction, and prevent the mixed material from flowing directly along the barrel wall of the material barrel 310 or directly from top to bottom to the discharge port of the material barrel 310.

[0060] like Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, a flow box 340 is also included. The flow box 340 has a hollow cavity structure. The flow box 340 is horizontally arranged at the outer bottom of the material barrel 310, and the cavity of the flow box 340 is connected with the discharge port of the material barrel 310 and the stirring device 320. The mixed material in the material barrel 310 enters the stirring device 320 through the flow box 340 for stirring. It should be noted that, on the one hand, the setting of the flow box 340 can conveniently improve the arrangement of the stirring device 320, avoid the small space at the bottom of the material barrel 310 hindering the installation of the stirring device 320, and at the same time, reserve enough space to facilitate the maintenance of the stirring device 320; on the other hand, the setting of the flow box 340 can also reserve pre-mixing space to avoid the defect of directly using the pipeline. When the pipeline is used directly, the diameter of the pipeline is too small, which will cause part of the solid raw materials to directly block the pipeline and affect the use. In the present application, the flow box 340 can be supported by the bracket 350 to reduce the force of the flow box 340 on the material barrel 310 and improve the stability of the connection between the flow box 340 and other components.

[0061] like Figure 3 , Figure 4 and Figure 6As shown, in some specific embodiments of the present invention, the stirring device 320 includes a first shell 321, a second shell 323, a third shell 324, a fourth shell 325 and a stirring motor 326. The first shell 321, the second shell 323, the third shell 324 and the fourth shell 325 are arranged vertically from bottom to top and are connected in sequence by bolts, the stirring motor 326 is installed at the upper end of the fourth shell 325, and the motor shaft of the stirring motor 326 is arranged vertically. The first shell 321, the second shell 323, the third shell 324 and the fourth shell 325 all have a hollow cavity structure and the cavities of the first shell 321 and the second shell 323 are connected, and a stirring mechanism 322 is arranged in the cavity of the first shell 321. The cavity of the second shell 323 is connected to the cavity of the flow box 340, so that the mixed material in the material barrel 310 flows out from the discharge port of the material barrel 310 and enters the cavity of the second shell 323 through the flow box 340, and then enters the cavity of the first shell 321 from the cavity of the second shell 323 and is stirred by the stirring mechanism 322.

[0062] Further, the stirring mechanism 322 includes a stirring shaft 3222 and a plurality of stirring blades 3221. The stirring shaft 3222 is arranged vertically, and a plurality of stirring blades 3221 are vertically evenly distributed at the lower end of the stirring shaft 3222 and fixedly connected to the lower end side wall of the stirring shaft 3222; the upper end of the stirring shaft 3222 passes through the cavities of the first shell 321, the second shell 323, the third shell 324 and the fourth shell 325 in sequence and is connected to the motor shaft of the stirring motor 326, and the stirring motor 326 drives the stirring shaft 3222 to drive the stirring blades 3221 to rotate to stir the mixed material entering the first shell 321. It should be noted that the number of stirring blades 3221 can be adjusted according to actual needs on the premise of fully stirring the mixed material, and is not specifically limited in this application. During the stirring process, the continuously flowing mixed material can be used to cool the stirring shaft 3222 to achieve self-cooling.

[0063] Specifically, the stirring mechanism 322 also includes a support plate 3223 and a connecting cylinder 3224. The support plate 3223 is horizontally arranged at the bottom end of the stirring shaft 3222. The support plate 3223 is disc-shaped as a whole, and there is a gap between its edge and the cavity of the first shell 321, so that the mixed material after stirring can be fully discharged; the support plate 3223 is fixedly connected to the bottom end of the stirring shaft 3222 by screws. The connecting cylinder 3224 is vertically arranged at the upper end of the support plate 3223, and the connecting cylinder 3224 has a hollow cavity structure. A plurality of stirring blades 3221 are vertically evenly distributed on the circumferential outer side wall of the connecting cylinder 3224 and abut against the upper end of the support plate 3223. The connecting cylinder 3224 is inserted into the stirring shaft 3222 and is interference-connected with the stirring shaft 3222 to prevent the mixed material from entering the gap between the two.

[0064] Furthermore, a plurality of notch grooves 3241 are circumferentially formed on the lower side wall of the third housing 324, and the notch grooves 3241 are used for heat dissipation. The notch grooves 3241 are arranged according to actual needs and are not specifically limited in the present application.

[0065] like Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, the conveying device 330 includes a first pipe 331, a second pipe 332 and a third pipe 333. One end of the first pipe 331 extends into the cavity of the first shell 321 so that the cavity of the first pipe 331 is connected to the cavity of the first shell 321; one end of the third pipe 333 extends into the upper cavity of the material barrel 310 so that the cavity of the third pipe 333 is connected to the cavity of the material barrel 310; the other end of the third pipe 333 is connected to the second feeding pipe 220; the two ends of the second pipe 332 are respectively connected to the first pipe 331 and the third pipe 333. Before the pulping machine 300 transports the fully and evenly stirred slurry to the slurry storage barrel 400 through the second feeding pipe 220, the mixed material stirred by the stirring mechanism 322 is sent to the material barrel 310 through the first pipe 331, the second pipe 332 and the third pipe 333 for re-stirring so that the mixed material in the material barrel 310 is stirred more fully.

[0066] Furthermore, one-way valves 334 are provided on the first pipeline 331, the second pipeline 332 and the third pipeline 333, which are used to control the connection or disconnection between the first pipeline 331, the second pipeline 332 and the third pipeline 333 and the connection or disconnection between the second pipeline 332, the third pipeline 333 and the second feeding pipeline 220. The connection port of the first pipeline 331 and the second pipeline 332 is located between the stirring device 320 and the one-way valve 334 on the first pipeline 331; the connection port of the second pipeline 332 and the third pipeline 333 is located between the two one-way valves 334 on the third pipeline 333.

[0067] When the stirring device 320 is working, that is, when the stirring mechanism 322 is working, in order to fully stir the mixed material to form a slurry with an initial water-to-material ratio, the conveying device 330 can be configured as follows: the one-way valve 334 on the first pipeline 331 is closed to prevent the mixed material from being discharged to the outside; and the one-way valve 334 on the second pipeline 332 is opened; and the one-way valve 334 on the left side (i.e., the side close to the material barrel 310) of the third pipeline 333 is opened, so that the second pipeline 332 is connected to the third pipeline 333; the one-way valve 334 on the right side (i.e., the side away from the material barrel 310) of the third pipeline 333 is closed, so that the third pipeline 333 is disconnected from the second feeding pipeline 220. According to this configuration, the first pipeline 331, the second pipeline 332 and the third pipeline 333 form a closed pipeline, so that the mixed material can be stirred by the stirring mechanism 322 repeatedly, thereby forming a slurry that is stirred evenly and fully.

[0068] When it is necessary to convey the mixed slurry to the slurry storage barrel 400, the conveying device 330 can be configured as follows: the one-way valve 334 on the first pipeline 331 is closed to prevent the mixed material from being discharged to the outside; and the one-way valve 334 on the second pipeline 332 is opened; and the one-way valve 334 on the left side (i.e., the side close to the material barrel 310) of the third pipeline 333 is closed, and the one-way valve 334 on the right side (i.e., the side away from the material barrel 310) of the third pipeline 333 is opened, so that the third pipeline 333 is connected to the second feeding pipeline 220. Such a configuration makes the pipeline connection between the pulping machine 300 and the slurry storage barrel 400 convenient for slurry conveying.

[0069] like Figure 7 As shown, in some specific embodiments of the present invention, a reflux port 3331 is provided on the side wall of one end of the third pipe 333 extending into the material barrel 310 toward the center of the material barrel 310. The reflux port 3331 is in an elongated strip shape, which can increase the cross-sectional area of ​​the outlet, so that the refluxed mixed material flows out in a wide and flat shape, and also allows the mixed material itself to flow, thereby spontaneously promoting mixing.

[0070] like Figure 5 and Figure 7 As shown, in some specific embodiments of the present invention, a plurality of separation sheets 312 are evenly distributed circumferentially on the side wall of the upper cavity of the material barrel 310, and the reflux port 3331 is located at the bottom of the separation sheet 312, so that the separation sheet 312 can block the refluxed mixed material and prevent the mixed material from splashing to the outside of the material barrel 310.

[0071] Furthermore, the length of the reflux port 3331 can be made greater than the width of the separation sheet 312, so as to increase the outflow width of the mixed material as much as possible while avoiding the mixed material from splashing outward, thereby greatly promoting the flow of the mixed material.

[0072] Furthermore, the side of the separation sheet 312 close to the center of the material barrel 310 can be set as an inclined surface, which can extend the contact length between the separation sheet 312 and the reflowing mixed material, thereby promoting the separation sheet 312 to cut the reflowing mixed material and improve the stirring effect.
