Description

Technical Field

[0001] The utility model relates to the technical field of pulping, in particular to a pulping device. Background Art

[0029] See also Figure 1 and Figure 2 The pulping equipment 10 in the preferred embodiment of the utility model includes a mixing module 100 , a dispersion module 200 and a conveying pipe 300 .

[0030] The mixing module 100 is used to perform the operation of mixing powder and liquid materials and prepare primary slurry; the primary slurry prepared by the mixing module 100 can be transported to the dispersion module 200 through the delivery pipe 300; the dispersion module 200 is used to perform dispersion operations on the primary slurry until a slurry with parameters such as viscosity and particle size that meet the requirements is obtained.

[0031] The mixing module 100 includes a pulping machine 110, a first delivery pump 120, a first cooler 130 and a first circulation tank 140. The outlet of the first circulation tank 140 is connected to the inlet of the first delivery pump 120, the outlet of the first delivery pump 120 is connected to the inlet of the first cooler 130, the outlet of the first cooler 130 is connected to the inlet of the pulping machine 110, and the outlet of the pulping machine 110 is connected to the inlet of the first circulation tank 140. Liquid material can be input through the first circulation tank 140, and powder can be added through the pulping machine 110; driven by the first delivery pump 120, the liquid material in the first circulation tank 140 can enter the pulping machine 110 through the first cooler 130, and be mixed with the powder under the action of the pulping machine 110. Moreover, driven by the first delivery pump 120, the mixture of powder and liquid material can circulate along the route of the slurry mixer 110, the first circulation tank 140, the first cooler 130 and the slurry mixer 110 until the solid content and the uniformity of mixing in the mixture reach the expected level, and the primary slurry can be obtained.

[0032] The dispersion module 200 includes a disperser 210, a second delivery pump 220, a second cooler 230, a second circulation tank 240, and a third circulation tank 250. The outlets of the second circulation tank 240 and the third circulation tank 250 are both connected to the inlet of the second delivery pump 220, the outlet of the second delivery pump 220 is connected to the inlet of the second cooler 230, the outlet of the second cooler 230 is connected to the inlet of the disperser 210, and the outlet of the disperser 210 is connected to the inlet of the second circulation tank 240 and the third circulation tank 250.

[0033] The mixing module 100 is connected to the inlet of the second circulation tank 240 through the delivery pipe 300. Specifically, the two ends of the delivery pipe 300 in this embodiment are respectively connected to the outlet of the first cooler 130 and the inlet of the second circulation tank 240. It can be seen that the primary slurry prepared by the mixing module 100 can be transported from the first cooler 130 to the second circulation tank 240 through the delivery pipe 300, and stored in the second circulation tank 240. Obviously, in other embodiments, the end of the delivery pipe 300 away from the second circulation tank 240 can also be connected to the first circulation tank 140 or other components in the mixing module 100.

[0034] Driven by the second delivery pump 220, the primary slurry stored in the second circulation tank 240 enters the disperser 210 through the second cooler 230, and the disperser 210 performs a dispersion operation on the primary slurry. Moreover, after the primary slurry is dispersed for the first time by the disperser 210, it returns to the second circulation tank 240 and the third circulation tank 250, and can enter the disperser 210 again for dispersion under the drive of the second delivery pump 220. Optionally, the primary slurry in the dispersion module 200 can be circulated along the path of the second circulation tank 240-disperser 210-third circulation tank 250-disperser 210-second circulation tank 240. In this way, after multiple cycles, the primary slurry can be dispersed multiple times by the disperser 210 and meet the dispersion requirements to form a finished slurry.

[0035] Furthermore, during the process of the dispersion module 200 dispersing the primary slurry, the mixing module 100 can simultaneously perform the operation of mixing the powder material with the liquid material, thereby preparing a new primary slurry. In this way, the efficiency of the pulping device 10 can be significantly improved.

[0036] In addition, the pulping machine 110 and the first circulation tank 140 are arranged in a first direction, and the first delivery pump 120 and the first cooler 130 are located between the pulping machine 110 and the first circulation tank 140. The first direction refers to Figure 1 Thus, the pipelines between the pulping machine 110, the first circulation tank 140, the first delivery pump 120 and the first cooler 130 are generally arranged along the first direction.

[0037] In this embodiment, the inlet and outlet of the first circulation tank 140 are located at the top and bottom respectively, the inlet and outlet of the first cooler 130 are located at the bottom and top respectively, and the inlet and outlet of the pulping machine 110 are both located at the top.

[0038] like Figure 2 As shown, the inlet and outlet of the first circulation tank 140 are located at the upper end and the lower end respectively; the first cooler 130 is a vertical cooler, and its inlet and outlet are located at the lower end and the upper end respectively; the inlet and outlet of the pulping machine 110 are both located at the upper end. It can be seen that the height difference between the outlet of the first circulation tank 140 and the inlet of the first cooler 130 is small, the height difference between the outlet of the first cooler 130 and the inlet of the pulping machine 110 is small, and the height difference between the outlet of the pulping machine 110 and the inlet of the first circulation tank 140 is also small. Therefore, the length of the pipeline between the pulping machine 110, the first circulation tank 140, the first delivery pump 120 and the first cooler 130 can be effectively shortened and the number of elbows required for the pipeline turning can be reduced, which helps to reduce the processing cost and assembly difficulty, and simplifies the structure of the mixing module 100.

[0039] More specifically, in this embodiment, the outlet of the first circulation tank 140 is connected to the inlet of the first delivery pump 120 through the first pipeline 101, the outlet of the first delivery pump 120 is directly connected to the inlet of the first cooler 130, the outlet of the first cooler 130 is connected to the inlet of the pulping machine 110 through the second pipeline 102, and the outlet of the pulping machine 110 is connected to the inlet of the first circulation tank 140 through the third pipeline 103. Directly connecting the outlet of the first delivery pump 120 to the inlet of the first cooler 130 does not require pipeline communication, which can reduce the number of pipelines, thereby further simplifying the structure of the mixing module 100.

[0040] For further information, please also refer to Figure 3 In this embodiment, the first delivery pump 120 and the first cooler 130 are at least partially stacked in the vertical direction, the inlet of the first cooler 130 is located at the bottom and is arranged downward, and the outlet of the first delivery pump 120 is arranged upward and opposite to the inlet of the first cooler 130. By stacking the first delivery pump 120 and the first cooler 130, the three-dimensional space can be effectively utilized to reduce the floor space of the mixing module 100. At the same time, it is convenient to directly connect the outlet of the first delivery pump 120 with the inlet of the first cooler 130.

[0041] Also, please refer again to Figure 1 and Figure 2In this embodiment, a discharge control valve 150 is connected to the side of the first pipe 101. The discharge control valve 150 is connected to the first pipe 101 and can be opened or closed. In the normal pulping process, the discharge control valve 150 remains closed; when the mixing module 100 is cleaned after the pulping is completed, the discharge control valve 150 is opened, and the residual slurry in the mixing module 100 can be discharged from the discharge control valve 150 through the first pipe 101. Moreover, since the first pipe 101 is approximately located at the lowest point of the mixing module 100, the discharge control valve 150 is arranged in the first pipe 101 to facilitate the residual slurry to flow out under the action of gravity.

[0042] Furthermore, the dispersion module 200 and the mixing module 100 are arranged along a second direction perpendicular to the first direction. The second direction refers to Figure 1 It can be seen that the dispersion module 200 and the mixing module 100 are independent of each other and only the first cooler 120 is connected to the second circulation tank 240 through the delivery pipe 300, so the internal pipes of the mixing module 100 and the dispersion module 200 do not cross and do not interfere with each other.

[0043] Moreover, the second circulation tank 240 and the third circulation tank 250 are arranged along the second direction and are spaced apart from the disperser 210 along the first direction, and the second delivery pump 220 and the second cooler 230 are located between the disperser 210 and the second circulation tank and the third circulation tank 250. Similarly, the pipelines between the disperser 210, the second circulation tank 240, the third circulation tank 250, the second delivery pump 220, and the second cooler 230 are also arranged roughly along the first direction. Moreover, the pipeline between the second circulation tank 240 and the third circulation tank 250 is arranged roughly along the second direction.

[0044] As can be seen from the above, the internal pipes of the mixing module 100 and the dispersion module 200 are distributed in a horizontal and vertical manner, so the pipe layout of the pulping equipment 10 is simple and the structure is relatively simple, which brings convenience to the disassembly, maintenance, cleaning and transportation of the equipment. After the pipe layout of the pulping equipment 10 is optimized, the resistance along the way of the slurry in the pipe can also be reduced, thereby improving the pulping capacity. Moreover, since the pipe layout is simpler, the amount of slurry remaining in the pipe is reduced, and less slurry will be wasted during the equipment cleaning process, thereby improving the utilization rate of the material.

[0045] In this embodiment, the inlet and outlet of the second circulation tank 240 and the third circulation tank 250 are respectively located at the top and bottom, the inlet and outlet of the second cooler 230 are respectively located at the bottom and top, and the inlet and outlet of the disperser 210 are both located at the top.

[0046] like Figure 2As shown, the inlet and outlet of the second circulation tank 240 are respectively located at the upper end and the lower end, and the inlet and outlet of the third circulation tank 250 are also respectively located at the upper end and the lower end; the second cooler 230 adopts a vertical cooler, and its inlet and outlet are respectively located at the lower end and the upper end; the inlet and outlet of the disperser 210 are both located at the upper end. It can be seen that the outlet of the second circulation tank 240 and the third circulation tank 250 has a small height difference with the inlet of the second cooler 230, the outlet of the second cooler 230 has a small height difference with the inlet of the disperser 210, and the outlet of the disperser 210 has a small height difference with the inlet of the second circulation tank 240 and the third circulation tank 250. Therefore, the length of the pipeline between the disperser 210, the second circulation tank 240, the third circulation tank 250, the second delivery pump 220, and the second cooler 230 can be effectively shortened and the number of elbows required for the pipeline to turn can be reduced, thereby helping to reduce processing costs and assembly difficulty, and further simplifying the structure of the dispersion module 200.

[0047] Specifically, in the present embodiment, the outlets of the second circulation tank 240 and the third circulation tank 250 are connected to the fourth branch pipe 201 and the fifth branch pipe 202 respectively, the fourth branch pipe 201 and the fifth branch pipe 202 are connected to the inlet of the second delivery pump 220 through the sixth main pipe 203, the outlet of the second delivery pump 220 is directly connected to the inlet of the second cooler 230, the outlet of the second cooler 230 is connected to the inlet of the disperser 210 through the seventh pipe 204, the outlet of the disperser 210 is connected to the eighth main pipe 205, and the eighth main pipe 205 is connected to the inlets of the second circulation tank 240 and the third circulation tank 250 through the ninth branch pipe 206 and the tenth branch pipe 207 respectively.

[0048] The outlet of the second delivery pump 220 is directly connected to the inlet of the second cooler 230, and there is no need to use pipelines to communicate, which can reduce the number of pipelines, thereby further simplifying the structure of the dispersion module 200. In addition, the four branch pipes 201 and the fifth branch pipe 202 cooperate with the sixth main pipe 203 to form a T-shaped pipeline layout, and the slurry flowing to the second cooler 230 is also collected by the sixth main pipe 203; and the ninth branch pipe 206 and the tenth branch pipe 207 cooperate with the eight main pipes 205 to form a T-shaped pipeline layout, and the slurry flowing from the disperser 210 into the second circulation tank 240 and the third circulation tank 250 can be collected through the eight main pipes 205. It can be seen that the internal pipeline layout of the dispersion module 200 is more reasonable and the line is simpler.

[0049] For further information, please refer again to Figure 3In this embodiment, the second delivery pump 220 and the second cooler 230 are at least partially stacked in the vertical direction, the inlet of the second cooler 230 is located at the bottom and is arranged downward, and the outlet of the second delivery pump 220 is arranged upward and opposite to the inlet of the second cooler 230. By stacking the second delivery pump 220 and the second cooler 230, the three-dimensional space can be effectively utilized to reduce the floor space of the dispersion module 200. At the same time, it is convenient to directly connect the outlet of the second delivery pump 220 with the inlet of the second cooler 230.

[0050] In this embodiment, a slurry mixing feed control valve 160 is provided between the outlet of the first cooler 130 and the inlet of the slurry mixing machine 110 , and a dispersed feed control valve 260 is provided between the outlet of the second cooler 230 and the inlet of the disperser 210 .

[0051] Specifically, the combined slurry feed control valve 160 can be arranged at the outlet of the first cooler 130, and the dispersed feed control valve 260 can be arranged at the outlet of the second cooler 230. It can be seen that the slurry flow direction can be controlled by controlling the opening and closing of the combined slurry feed control valve 160 and the dispersed feed control valve 260, which is easy to operate and can effectively avoid the occurrence of misoperation.

[0052] Please also read Figure 4 In this embodiment, the first cooler 130 is detachably connected to the first delivery pump 120, the pulping machine 110 and the delivery pipe 300, and the second cooler 230 is detachably connected to the second delivery pump 220 and the disperser 210. The pulping equipment 10 has a simplified state in which the first cooler 130 and the second cooler 230 are removed. During the slurry preparation process, the first cooler 130 and the second cooler 230 can be removed under the condition of low heat generation to simplify the structure of the mixing module 100 and the dispersion module 200 and shorten the pipeline length, thereby reducing the resistance of the slurry in the mixing module 100 and the dispersion module 200 and improving the circulation efficiency.

[0053] Furthermore, the pulping device 10 further includes a first connecting pipe 170 and a second connecting pipe 270, and when the pulping device 10 is switched to the simplified state, the three interfaces of the first connecting pipe 170 are respectively connected to the outlet of the first delivery pump 120, the inlet of the pulping machine 110 and the delivery pipe 300. The two interfaces of the second connecting pipe 270 are respectively connected to the outlet of the second delivery pump 220 and the inlet of the disperser 210.

[0054] When the pulping equipment 10 is switched to the simplified state, the inlet of the pulping machine 110 is connected to the outlet of the first delivery pump 120 through the first connecting pipe 170, and the delivery pipe 300 is connected to the first connecting pipe 170; the inlet of the disperser 210 is connected to the outlet of the second delivery pump 220 through the second connecting pipe 270.

[0055] Furthermore, in this embodiment, a first rolling assembly 131 is provided at the bottom of the first cooler 130, and a second rolling assembly 231 is provided at the bottom of the second cooler 230. The first rolling assembly 131 and the second rolling assembly 231 have the same structure, and may be a roller, a universal wheel, etc., so that the first cooler 130 and the second cooler 230 can be easily pushed apart when the first cooler 130 and the second cooler 230 are disassembled.

[0056] In the above pulping equipment 10, the mixing module 100 and the dispersing module 200 are arranged along the second direction, and the two are independent of each other and are only connected through the conveying pipe 300, so the internal pipes of the mixing module 100 and the dispersing module 200 do not cross and do not interfere with each other. Furthermore, the pipes between the pulping machine 110, the first circulation tank 140, the first delivery pump 120 and the first cooler 130 are all arranged roughly along the first direction. Similarly, the pipes between the disperser 210, the second circulation tank 240, the third circulation tank 250, the second delivery pump 220, and the second cooler 230 are also arranged roughly along the first direction. Moreover, the pipes between the second circulation tank 240 and the third circulation tank 250 are arranged roughly along the second direction. It can be seen that the internal pipes of the mixing module 100 and the dispersing module 200 are distributed in a horizontal and vertical manner, so the pipe layout of the above pulping equipment 10 is simple and the structure is relatively simple.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
