Description

Technical Field

[0001] The utility model relates to the technical field of papermaking, in particular to an automatic slurry concentration regulating device. Background Art

[0002] During the storage process, the pulp slurry's concentration changes due to evaporation of water. When the slurry is used, it is necessary to add water or materials to adjust the concentration before entering the next process flow. Since the secondary concentration adjustment takes a certain amount of time, the factory will mix the pulp in the slurry pool before using it, take samples and measure the concentration, and then adjust the concentration.

[0003] In the daily adjustment process of the existing slurry adjustment concentration adjustment device, it is necessary to stir the slurry and the newly added raw materials to speed up the slurry concentration adjustment process. However, when using the traditional multi-stirring rod stirring frame for stirring, the overall slurry is stirred too violently, and the slurry is easy to splash and adhere to the cavity wall and cover of the adjustment tank, which not only causes slurry waste but also brings trouble to subsequent cleaning.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The utility model provides a technical solution: a slurry concentration automatic adjustment device, comprising an adjustment tank 1, a cover plate 2 arranged on the adjustment tank 1 and a concentration monitoring component arranged in the inner cavity of the adjustment tank 1, a feed pipe 3 and a water inlet pipe 4 are respectively arranged on the cover plate 2, a drive motor 5 is fixedly connected to the cover plate 2, an intermediate shaft 6 is fixedly connected to the output shaft end of the drive motor 5, a scraper rod 7 is fixedly connected to the intermediate shaft 6, a circulating pump 13 is arranged outside the adjustment tank 1, and the inlet and outlet ends of the circulating pump 13 are connected to the adjustment tank 1 through a first material pipe 14 and a second material pipe 15 respectively, and a discharge pipe 11 is arranged on the lower end surface of the adjustment tank 1.

[0024] The utility model, by providing an intermediate shaft 6 and a scraper rod 7, can be driven by a driving motor 5 to enable the scraper rod 7 to scrape off the slurry adhered to the tank cavity wall; by providing a circulating pump 13, a first material pipe 14 and a second material pipe 15, the slurry in the regulating tank 1 can circulate under the action of the circulating pump 13, and at the same time, under the action of the scraper rod 7, the slurry in the flowing state can be stirred, thereby further accelerating the slurry concentration adjustment process.

[0025] Reference Figure 3 As shown, the concentration monitoring assembly includes a plurality of monitoring probes 10 arranged in the inner cavity of the regulating tank 1, an open slot 51 matching the monitoring probe 10 is arranged on the scraper rod 7, and a solenoid valve electrically connected to the monitoring probe 10 is arranged on the feed pipe 3 and the water inlet pipe 4. When the monitoring probe 10 detects that the concentration in the regulating tank 1 is not the predetermined concentration, the signal can be transmitted to the solenoid valve on the feed pipe 3 or the water inlet pipe 4, so as to quantitatively introduce water or raw materials into the regulating tank 1, thereby facilitating the subsequent stirring and mixing adjustment of the slurry concentration in the regulating tank 1; due to the arrangement of the open slot 51 matching the monitoring probe 10, the monitoring probe 10 can be fully extended into the inner cavity of the regulating tank 1 during the installation process, and during the sealing process, it is only necessary to seal the through hole or slot on the mounting base of the monitoring probe 10 and the cavity wall of the regulating tank 1, which greatly simplifies the sealing process of the entire sealing tank.

[0026] Reference Figure 2 and 4As shown, when the monitoring probe 10 needs to be disassembled and replaced on a daily basis, the monitoring probe 10 can be disassembled as a whole by simply removing the mounting plate 9 in the mounting groove 8, effectively reducing the time required for daily maintenance and replacement of the monitoring probe 10. The outer surface of the regulating tank 1 body is provided with a mounting groove 8, and a mounting plate 9 is detachably installed in the mounting groove 8, and the monitoring probe 10 is detachably installed on the mounting plate 9.

[0027] The first material pipe 14 is arranged at the lower part of the regulating tank 1 , and the second material pipe 15 is arranged at the upper part of the regulating tank 1 . The first material pipe 14 is communicated with the inlet end of the circulation pump 13 , and the second material pipe 15 is communicated with the outlet end of the circulation pump 13 .

[0028] Reference Figure 3 and 4 As shown, the first material pipe 14 penetrates deep into the inner cavity of the regulating tank 1 and contacts the bottom of the cavity of the regulating tank 1, and the lower part of the scraper rod 7 is provided with a chamfered part matching the first material pipe 14. Since the first material pipe 14 and the second material pipe 15 are connected up and down and arranged at the upper and lower parts of the regulating tank 1, respectively, it can ensure that the circulation pump 13 can circulate the slurry in the regulating tank 1 thoroughly. At the same time, it effectively avoids the situation that the slurry in the lower part of the inner cavity of the regulating tank 1 cannot be circulated and sucked due to the limitation of the installation of the first material pipe 14.

[0029] An extension plate 12 is provided on the regulating tank 1 , and a circulation pump 13 is fixedly connected to the extension plate 12 .
