Description

Technical Field

[0001] The utility model relates to the technical field of papermaking pulping, in particular to a slurry storage tower facilitating slurry circulation. Background Technique

[0002] At present, when producing corrugated paper in the papermaking industry, the general pulping process is that the slurry after being processed by the pulping system and the coarse screening system is subjected to classification treatment. The classified slurry is divided into long fiber pulp and short fiber pulp. The short fiber pulp is sent to the slurry storage tower after passing through the low-concentration sand removal system, multi-tray concentration system and heat dispersion system, and then sent to the paper machine for pulp preparation. The processed short fiber pulp is mainly used for the surface layer of corrugated paper. The pulp pond is an auxiliary unit for storing, mixing slurry and system buffering in the papermaking process. With the development of the economic scale of papermaking and the continuous improvement of the degree of automatic control, the continuous mixing function of the pulp pond becomes more important. The structure of the pulp pond and the stirring and mixing effect directly affect the effective volume of pulp storage, floor area, investment, and the efficient, economic, safe and reliable operation of the system.

[0003] The existing slurry storage tower lacks a mixing structure inside. When the slurry stays in the slurry storage tower, the solid mixture in the slurry will accumulate at the bottom of the slurry storage tower, thus affecting the use quality of the paper slurry when taken out later. Therefore, there is an urgent need for a slurry storage tower facilitating slurry circulation. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution for a slurry storage tower facilitating slurry circulation:

[0024] A slurry storage tower facilitating slurry circulation includes an equipment base 1 and a slurry storage cylinder 2 placed above the equipment base 1. A tooth ring 3 is fixedly installed in the middle of the side wall of the slurry storage cylinder 2. A driving assembly 4 for rotating the slurry storage cylinder 2 is arranged in the middle of the upper end surface of the equipment base 1. A mixing column 5 is rotatably installed in the inner cavity of the slurry storage cylinder 2. Stirring assemblies 6 for rotating the mixing column 5 are arranged on the front and rear sides of the upper end surface of the equipment base 1. A connecting cylinder 7 is fixedly installed on the rear end surface of the slurry storage cylinder 2, and a liquid injection assembly 8 is arranged on the side wall of the connecting cylinder 7.

[0025] Furthermore, the driving assembly 4 includes vertical plates 41 fixedly installed on the left and right sides of the upper end of the equipment base 1. A gear 42 is rotatably installed in the inner cavity of the vertical plate 41. The gear 42 is meshed with the tooth ring 3. A driving motor 43 is fixedly installed on the front end surface of the vertical plate 41 on the right side through a frame. The output shaft end of the driving motor 43 is fixedly connected to the gear 42 on the right side;

[0026] The stirring assembly 6 includes a worm gear 61 fixedly installed on the side wall of the mixing column 5, and a stirring motor 62 fixedly installed on the front side of the upper end of the equipment base 1 through a frame. A worm 63 is fixedly installed at the output shaft end of the stirring motor 62, and the worm 63 is meshed and connected with the worm gear 61;

[0027] Stirring rods 51 are fixedly installed on the side wall of the mixing column 5. The stirring rods 51 are arranged in a conical shape. Stirring blades 21 are fixedly installed on the front and rear sides of the inner wall of the slurry storage barrel 2, and the stirring blades 21 on the front and rear sides are arranged in central symmetry.

[0028] It should be noted that by starting the driving motor 43, the right-side gear 42 rotates. Since the gear 42 is meshed and connected with the gear ring 3, at this time, the gear 42 will drive the gear ring 3 to make the slurry storage barrel 2 rotate clockwise. Since there are stirring blades 21 arranged in the slurry storage barrel 2, at this time, as the slurry storage barrel 2 rotates continuously, the stirring blades 21 can stir and mix the slurry in the slurry storage barrel 2 to a certain extent; synchronously start the stirring motor 62 to make the worm 63 rotate. Since the worm 63 is meshed and connected with the worm gear 61, at this time, the worm gear 61 will drive the mixing column 5 to rotate counterclockwise. Along with the rotation of the stirring rods 51 fixed on the side wall of the mixing column 5, the stirring rods 51 can break up the slurry, further improving the mixing efficiency of the entire equipment for the slurry, thereby ensuring the quality of the slurry stored in the slurry storage barrel 2.

[0029] Furthermore, the liquid injection assembly 8 includes a connecting ring 81 rotatably installed on the side wall of the connecting cylinder 7. A slurry injection pipe 82 and a liquid injection pipe 83 are fixedly installed on the side wall of the connecting ring 81. The connecting cylinder 7 is communicated with the slurry storage barrel 2. Liquid inlet holes 711 are opened on the side wall of the connecting cylinder 7, and several groups of liquid inlet holes 711 are provided in total;

[0030] Brackets 9 are rotatably installed on the side walls of both the connecting cylinder 7 and the mixing column 5. A waterproof camera 22 is fixedly installed on the inner wall of the slurry storage barrel 2, and a discharge pipe 23 is fixedly installed on the front side wall of the slurry storage barrel 2.

[0031] It should be noted that since the slurry injection pipe 82 and the liquid injection pipe 83 are fixedly installed on the side wall of the connecting ring 81, workers can input the slurry to be stored into the slurry storage barrel 2 through the slurry injection pipe 82. After that, workers can implement detection on the state of the slurry in the slurry storage barrel 2 through the waterproof camera 22. Water is injected into the connecting ring 81 through the liquid injection pipe 83. At this time, the water flow can enter the slurry storage barrel 2 through the connecting ring 81 and the connecting cylinder 7 to increase the proportion of clear water in the slurry, avoiding the slurry being too viscous and affecting the use when taken out. Through the setting of the discharge pipe 23, workers can quickly take out the slurry in the inner cavity of the slurry storage barrel 2.

[0032] Working principle:

[0033] A grouting pipe 82 and a liquid injection pipe 83 are fixedly installed on the side wall of the connecting ring 81. Workers can input the slurry to be stored into the slurry storage cylinder 2 through the grouting pipe 82. After that, workers can implement the detection of the state of the slurry in the slurry storage cylinder 2 through the waterproof camera 22;

[0034] By periodically starting the driving motor 43 to make the right gear 42 rotate. Since the gear 42 is meshed and connected with the gear ring 3, at this time, the gear 42 will drive the gear ring 3 to make the slurry storage cylinder 2 rotate clockwise. Since the stirring blades 21 are arranged in the slurry storage cylinder 2, at this time, with the continuous rotation of the slurry storage cylinder 2, the stirring blades 21 can stir and mix the slurry in the slurry storage cylinder 2 to a certain extent;

[0035] Synchronously start the stirring motor 62 to make the worm 63 rotate. Since the worm 63 is meshed and connected with the worm wheel 61, at this time, the worm wheel 61 will drive the mixing column 5 to rotate counterclockwise. Along with the rotation of the stirring rod 51 fixed on the side wall of the mixing column 5, the stirring rod 51 can break up the slurry, further improving the mixing efficiency of the whole device for the slurry, thus ensuring the quality of the slurry stored in the slurry storage cylinder 2;

[0036] When the connecting cylinder 7 rotates, workers can inject water into the connecting ring 81 through the liquid injection pipe 83. At this time, the water flow can enter the slurry storage cylinder 2 through the connecting ring 81 and the connecting cylinder 7 to increase the proportion of clear water in the slurry, avoiding the slurry from being too viscous and affecting the use when taken out. Finally, through the setting of the discharge pipe 23, workers can quickly take out the slurry in the inner cavity of the slurry storage cylinder 2.

[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than a limitation on the protection scope of the present invention. Simple modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
