Description

Technical Field

[0001] The utility model belongs to the technical direction of sludge dehydration, and specifically relates to a screw stack sludge dehydrator with the function of monitoring and adjusting pH value. Background Art

[0002] The spiral stacking sludge dewatering machine, also known as the laminated spiral sludge dewatering machine, is a water treatment equipment widely used in municipal sewage treatment projects and petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industrial industries. The spiral stacking body of the dewatering machine is a filtering device formed by stacking fixed rings and movable rings on each other, and the spiral shaft runs through it. The front section is the concentration section, and the rear section is the dewatering section. The filter gap formed between the fixed ring and the movable ring and the pitch of the spiral shaft gradually decrease from the concentration section to the dewatering section. The rotation of the spiral shaft not only pushes the sludge from the concentration section to the dewatering section, but also continuously drives the movable ring to clean the filter gap to prevent blockage. After the sludge is concentrated by gravity in the concentration section, it is transported to the dewatering section. In the process of moving forward, as the filter gap and the pitch gradually become smaller, and under the blocking effect of the back pressure plate, a huge internal pressure is generated, and the volume continues to shrink, so as to achieve the purpose of full dehydration.

[0003] In the process of sludge dewatering in the prior art, the strength of the spiral blades is low, the spiral blades will be worn during the stirring process, the service life is short, and the noise is loud during operation. The pH value of the sludge cannot be adjusted, and the sludge needs to be poured out for pH value testing, which is a cumbersome operation. Utility Model Content

A first feed port 5 is provided on one side of the top of the U-shaped groove 4 to input the sludge. A second feed port 9 is provided on the other side of the top of the U-shaped groove 4 to transport an adsorbent to adjust the pH value of the sludge during the dehydration process. A lining strip 6 is detachably installed on the inner bottom surface of the U-shaped groove 4, corresponding to the position of the second feed port 9, to prevent the sludge from adhering to the dead corner and affecting the normal transportation, and at the same time, it can extend the service life of the U-shaped groove 4 and reduce the noise generated during operation. A pH value monitoring device 8 is fixedly installed on the inner wall of the first feed port 5 to detect the pH value of the sludge;

[0018] The driving device 7 is powered by an external power supply in the workshop, and the pH value monitoring device 8 is connected to the workshop work computer through a signal, which is convenient for staff to observe.

[0019] In this embodiment:

[0020] When the staff needs to dehydrate the sludge, the staff first turns on the power in the workshop. At this time, the driving device 7 starts and drives the spiral body 2 to rotate. Then the staff inputs the sludge from the first feed port 5 into the U-shaped trough 4 for stirring and dehydration. During the sludge input process, the pH value monitoring device 8 can detect the pH value of the sludge and send the data to the staff. At this time, the staff pours the adsorbent from the second feed port 9 into the U-shaped trough 4 according to the data fed back by the pH value monitoring device 8. The adsorbent can adsorb ions in the sewage, thereby reducing the ion concentration in the sewage to achieve the purpose of adjusting the pH value. After the spiral body 2 fully stirs the adsorbent and the sludge, the staff detects whether the pH value of the sludge meets the standard through the pH value monitoring device 8. If not, continue to add the adsorbent. When the pH value of the sludge meets the production requirements, the staff manually opens the built-in valve of the discharge port 1, and the dehydrated sludge will be discharged from the discharge port 1 to the collection device to wait for subsequent production processing;

[0021] By using two groups of feed ports in conjunction with the pH monitoring device 8, the pH value of the sludge can be detected while the sludge is being transported at the first feed port 5, and then the adsorbent is added from the second feed port 9. The spiral 2 can fully mix the adsorbent and the sludge to make the pH value more accurate. By using the lining strip 6 in conjunction with the sludge, it can prevent the sludge from adhering to dead corners and affecting normal transportation, thereby ensuring the transportation efficiency of the sludge.
