Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a pulp concentration detection device, including a pulp tank 1. Support legs 2 are evenly and fixedly arranged at the bottom of the pulp tank 1 to support the pulp tank 1. Feed ports 3 communicating with the inside of the pulp tank 1 are symmetrically arranged at the top of the pulp tank 1. A cover plate 4 is arranged at the top of the feed port 3 to prevent dust from entering the pulp tank 1 and affecting the detection result. A motor 5 is fixedly arranged at the center of the top of the pulp tank 1. The output shaft of the motor 5 passes downward through the pulp tank 1 and is fixedly provided with a first rotating shaft 6. A plurality of stirring rods 7 are evenly and fixedly arranged on the outer periphery of the first rotating shaft 6, and the stirring rods 7 stir the pulp.

[0019] A detection box 14 is fixedly arranged at the bottom of the pulp tank 1. A blanking port communicating with the detection box 14 is opened on the pulp tank 1, and the blanking port is circular. A second sector plate 12 is horizontally and fixedly arranged in the blanking port. A hollow fixed shaft 9 is fixedly sleeved at the bottom of the first rotating shaft 6. A one-way bearing 10 is fixedly sleeved in the hollow fixed shaft 9. A second rotating shaft 13 is fixedly sleeved in the one-way bearing 10. A first sector plate 11 is fixedly sleeved on the second rotating shaft 13. The first sector plate 11 is located in the blanking port and is rotationally and sealingly fitted with the inner wall of the blanking port, and the first sector plate 11 is rotationally and sealingly fitted with the second sector plate 12 to close or open the pulp tank 1.

[0020] A detection component for detecting the pulp concentration in the detection box 14 is arranged on the pulp tank 1. The detection component includes a concentration detector 17. The concentration detector 17 is fixedly arranged on the pulp tank 1. One end of the concentration detector 17 is connected with a detection line 18. The other end of the detection line 18 passes through the detection box 14 and extends into the detection box 14. A pulp outlet 16 communicating with the inside of the detection box 14 is arranged at the bottom of the detection box 14. A control valve 15 is arranged on the pulp outlet 16.

[0021] Inside the pulp tank 1, flow guiding plates 8 are symmetrically and fixedly arranged. The flow guiding plates 8 are inclined and do not hinder the rotation of the stirring rod 7, facilitating the pulp to flow into the detection tank 14 through the feeding port at the bottom of the pulp tank 1.

[0022] The working principle of a pulp concentration detection device provided by the present utility model is as follows:

[0023] In the initial state, the first sector plate 11 and the second sector plate 12 are in sealing fit to prevent the pulp from flowing into the detection tank 14.

[0024] When detecting the concentration of the pulp, the pulp is injected into the pulp tank 1 through the pulp inlet 3. After the injection is completed, the cover plate 4 is covered on the pulp inlet 3. The motor 5 is started, and the motor 5 drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the stirring rod 7 to rotate, and the stirring rod 7 stirs the pulp and prevents the pulp from solidifying. When the first rotating shaft 6 rotates, it does not drive the second rotating shaft 13 to rotate. Thus, the first sector plate 11 and the second sector plate 12 are in sealing fit to prevent the pulp from flowing into the detection tank 14 when the pulp is stirred, enabling the pulp to stay in the pulp tank 1 for a longer time and being stirred more fully.

[0025] When the stirring rod 7 stirs the pulp in the pulp tank 1 evenly, at this time, the output shaft of the motor 5 rotates in the reverse direction, and the motor 5 drives the first rotating shaft 6 to rotate in the reverse direction. At this time, the first rotating shaft 6 drives the second rotating shaft 13 to rotate through the one-way bearing 10, and the second rotating shaft 13 drives the first sector plate 11 to rotate. When the notch of the first sector plate 11 rotates to correspond to the notch of the second sector plate 12, the motor 5 stops working. At this time, the pulp in the pulp tank 1 flows into the detection tank 14 through the notches of the first sector plate 11, the second sector plate 12.

[0026] It is also possible to make the motor 5 continue to rotate. The motor 5 drives the first rotating shaft 6 and the second rotating shaft 13 to rotate continuously, so that the pulp in the pulp tank 1 intermittently flows into the detection tank 14. At the same time, the first rotating shaft 6 drives the stirring rod 7 to stir the pulp, further preventing the pulp from solidifying or stratifying.

[0027] Then, through the combined use of the concentration detector 17 and the detection line 18, the concentration of the pulp in the detection tank 14 is detected. After the detection is completed, the control valve 15 is controlled to open so that the pulp in the detection tank 14 is discharged through the pulp outlet 16.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
