[0001] The utility model relates to the technical field of separation screens, in particular to an inner spiral double-drum separation screen. Background Art

[0002] The separation screen is an important equipment commonly used in salt production. It mainly plays the role of material separation. However, in the process of separating salt and brine, a large amount of separated brine will splash out when encountering strong winds. In addition, the original multi-layer separation screen has a complex structure and high cost. It is also bulky and has high maintenance costs. Therefore, we propose an internal spiral double-drum separation screen. Utility Model Content

[0003] The purpose of the utility model is to provide an internal spiral double-drum separation screen, which has the advantages of improving the separation efficiency of salt and brine while avoiding splashing of the brine after separation due to strong winds, and has the advantages of simple structure, low cost and maintenance cost. It solves the problem that in the process of separating salt and brine, a large amount of separated brine will splash when strong winds are encountered in the current separation screen, and the original multi-layer separation screen has a relatively complex structure, high cost, and is bulky and has high maintenance costs.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an internal spiral double-drum separation screen, comprising a column, a feed pipe and a screening drum, two screening drums are fixedly installed on the upper surface of the column, two chute pipes are fixedly connected to the outer surface of the feed pipe, and the two chute pipes are respectively fixedly connected to one end of the two screening drums, a spiral screen is provided inside the two screening drums, a discharge pipe is fixedly connected to the end of the two screening drums facing away from the chute, a drainage port is provided on the lower surface of the two screening drums, and a sieve plate is fixedly installed inside the drainage port, a water collecting trough is fixedly installed on the lower surface of the two screening drums below the two sieve plates, and the two water collecting troughs are connected by a connecting pipe at one end close to the discharge pipe, and a drainage pipe is fixedly connected to the outer surface of the connecting pipe.

[0005] Preferably, a fixing seat is fixedly installed on the lower surface of the column, and mounting holes are provided on the upper surface of the fixing seat near the four corners.

[0006] Preferably, the angle between the screening drum and the horizontal plane is 15°<a<60°.

[0007] Preferably, a transmission shaft is rotatably installed inside the two screening drums, and the two spiral screens are respectively welded to the outer surfaces of the two transmission shafts.

[0008] Preferably, the outer surfaces of the two transmission shafts are fixedly sleeved with synchronous wheels, and the two synchronous wheels are connected by a synchronous belt transmission, and the two synchronous wheels and the synchronous belt are both located inside the transmission box.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] 1. The utility model achieves the effect of improving the separation efficiency of salt and brine while avoiding splashing of brine after separation due to strong winds by arranging a screening cylinder, a feed pipe, a chute, a spiral screen, a column, a water collection tank, a connecting pipe, a drain pipe and a discharge pipe. At the same time, the utility model has the effect of simple structure, low cost and maintenance cost. Salt and brine enter the screening cylinder through the feed pipe and the chute, and flow in a spiral under the action of the spiral screen. At the same time, the separated brine passes through the screen plate and flows into the water collection tank. The brine collected in the water collection tank is discharged through the connecting pipe and the drain pipe, and the separated salt is discharged through the discharge pipe. The entire separation process is in a closed state, so brine splashing due to strong winds will not occur. Compared with the original multi-layer separation screen, the structure is simpler, and the cost and maintenance cost are also lower.

[0011] 2. The utility model achieves the effect of preventing blockage inside the screening drum and facilitating the flow of salt and brine inside the screening drum by arranging a transmission shaft, a transmission box and a rotating motor. The rotating motor drives the transmission shaft to rotate, which assists in driving the spiral screen inside the screening drum to rotate, thereby forcing the salt inside the screening drum to flow and scraping off the salt adhering to the inner wall of the screening drum, thereby preventing blockage inside the screening drum and facilitating the flow of salt and brine inside the screening drum.

[0018] Example 1

[0019] like Figures 1-4 As shown, the utility model proposes an internal spiral double-drum separation screen, including a column 2, a feed pipe 3 and a screening drum 5. The lower surface of the column 2 is fixedly installed with a fixing seat 1. The upper surface of the fixing seat 1 is provided with mounting holes near the four corners. The fixing seat 1 can be fixed to the use position after the bolts pass through the mounting holes. Two screening drums 5 are fixedly installed on the upper surface of the column 2. Two chute pipes 4 are fixedly connected to the outer surface of the feed pipe 3, and the two chute pipes 4 are respectively fixedly connected to one end of the two screening drums 5. The angle a between the screening drum 5 and the horizontal plane is 15°-60°, so the salt and water are fed from the feed pipe 3 and the After the chute 4 enters the interior of the screening drum 5, it can flow inside the screening drum 5 under the action of gravity. A spiral screen 12 is provided inside the two screening drums 5. The ends of the two screening drums 5 facing away from the chute 4 are fixedly connected to the discharge pipe 9. The lower surfaces of the two screening drums 5 are provided with a drainage port 15, and a sieve plate 16 is fixedly installed inside the drainage port 15. A water collecting trough 6 is fixedly installed at a position below the two sieve plates 16 on the lower surfaces of the two screening drums 5, and the two water collecting troughs 6 are connected by a connecting pipe 11 at one end close to the discharge pipe 9. The outer surface of the connecting pipe 11 is fixedly connected to the drainage pipe 10.

[0020] When the present invention is in use, salt and brine enter the interior of the screening drum 5 through the feed pipe 3 and the chute 4, and flow under the action of gravity. Under the action of the spiral screen 12, the spiral flow is carried out, and the separated brine passes through the sieve plate 16 and flows into the water collecting tank 6. The brine collected in the water collecting tank 6 is discharged through the connecting pipe 11 and the drain pipe 10, and the separated salt is discharged through the discharge pipe 9. The entire separation process is in a closed state, and brine splashing will not occur due to strong winds. Compared with the original multi-layer separation screen, the structure is simpler, and the cost and maintenance cost are also lower.

A rotating motor 8 is fixedly installed on the outer surface of the transmission box 7. The end of the output shaft of the rotating motor 8 and the end of the transmission shaft 13 are fixedly connected. The outer surfaces of the two transmission shafts 13 are fixedly sleeved with synchronous wheels 14, and the two synchronous wheels 14 are connected by a synchronous belt transmission. The two synchronous wheels 14 and the synchronous belt are both located inside the transmission box 7. The rotating motor 8 drives one of the transmission shafts 13 to rotate, and the two transmission shafts 13 are synchronously transmitted through the synchronous wheel 14 and the synchronous belt.

[0023] In this embodiment, the rotating motor 8 drives the transmission shaft 13 to rotate, which assists in driving the spiral screen 12 inside the screening drum 5 to rotate, thereby forcing the salt inside the screening drum 5 to flow, and at the same time scraping off the salt adhering to the inner wall of the screening drum 5, thereby preventing blockage inside the screening drum 5 and facilitating the flow of salt and brine inside the screening drum 5.
