Detailed Description
As figure 1, a solid-liquid separation system of aquaculture wastewater ammonia nitrogen treatment system, including barrel 10 and the auger 20 of setting in the barrel, the barrel is fixed to be set up, the barrel slope sets up, auger place axle 21 is connected with the motor, the barrel is from the bottom to the top, the internal diameter grow gradually, feed inlet 11 on the barrel sets up the top position in the auger bottom, delivery port 12 on the barrel sets up the below position in the auger bottom, discharge gate 13 on the barrel sets up the top position at the auger.
In the patent document of application publication No. CN111977902a, waste water waste enters the opening 401 of the drum 4 in batches due to the presence of the blades 302. The present invention is an alternative to the solid-liquid separation system of patent document application publication No. CN111977902A, whereby waste water waste is also fed into the feed inlet 11 in batches.
A batch of waste water flows into the barrel 10 along the inlet 11 and waste water flows down the barrel. Referring to fig. 2, the waste water can flow down along the cylinder to the water outlet 12, and the waste material stays at different positions of the cylinder, specifically, the inner diameter of the cylinder is gradually increased from the bottom to the top, the gap between the inner side wall of the top of the cylinder and the packing auger 20 is larger, so that the waste material with larger shape can be blocked, and the gap between the inner side wall of the bottom of the cylinder and the packing auger is smaller, so that the waste material with smaller shape can be blocked. Under the drive of the motor, the auger 20 rotates to drive the waste materials to move upwards along the cylinder body. If the waste material in the barrel 10 does not accumulate to a certain amount, the waste material that moves upwards along the barrel falls back because of the gap between the packing auger and the inner side wall of the barrel is enlarged, and the waste material and the waste water with small shapes can be turned out from the waste material with large shapes in the process. The waste in the cylinder is accumulated to a certain amount, as shown in fig. 3 and 4, the waste below pushes the waste above to move upwards along the cylinder, and the waste reaching the top of the auger falls into the discharge port 13 and is discharged out of the cylinder 10. A material receiving container 50 is arranged below the discharge port.
The gap between the bottom of the packing auger 20 and the inner side wall of the cylinder 10 is the smallest, namely the gap between the edge of the bottommost part of the packing auger 20 and the inner side wall of the cylinder 10 is the smallest in all gaps between the packing auger and the inner side wall of the cylinder. The gap between the top of the packing auger and the inner side wall of the cylinder body is the largest, namely the gap between the edge of the top of the packing auger 20 and the inner side wall of the cylinder body 10 is the largest in all gaps between the packing auger and the inner side wall of the cylinder body. Between the maximum and minimum clearance, the clearance between auger and the barrel inside wall changes gradually.
The inlet is provided with a valve, which may alternatively be identical to and act in synchronism with the vane 302 of patent publication No. CN111977902A, which also opens the inlet 11 in a rotary manner when the vane opens the header 201 in a rotary manner. As the vanes 302 close the header 201 in a rotating manner, the valve also closes the feed port 11 in a rotating manner.
As an alternative to the valve, the valve takes the form of a valve plate, which is arranged inside the feed opening 11, as shown in fig. 1, i.e. the valve plate is located inside the cylinder 10. One side of the valve plate is hinged with one side of the feeding hole, one side of the feeding hole hinged with the valve plate is a lower part of the feeding hole, the other side of the valve plate can be abutted against the other side of the feeding hole (substantially, one side of the valve plate can be abutted against the inner side wall of the barrel body at the position of the feeding hole), and one side of the feeding hole abutted against the valve plate is a high part of the feeding hole. The hinged part of the valve plate 30 and the feed inlet 11 is provided with a torsion spring for resetting. In practical operation, a batch of waste water enters the feed inlet 11, washes open the valve plate 30, enters the cylinder 10, and then the valve plate 30 is closed under the action of the torsion spring. Because the waste material passively moves from bottom to top along the cylinder, and the side of the feed inlet hinged with the valve plate is the lower part of the feed inlet, the waste material moving upwards cannot open the valve plate, and only the valve plate is closed more tightly, as shown in figure 3.
Alternatively, the inlet 11 of the cylinder 10 is arranged in the middle of the packing auger 20, in which the packing auger 20 has a large distance from the inner side wall of the cylinder, and the valve plate 30 has a space opened into the cylinder, as shown in fig. 1 and 2.
As an improvement, as shown in figure 1, a plurality of small packing augers 40 are arranged between the packing auger 20 and the side wall of the cylinder body 10. The small packing auger is positioned at a larger gap between the packing auger 20 and the inner side wall of the cylinder body. The auger drives the waste material to move upwards along the cylinder, the waste material comes to the small auger 40, the auger 20 acts on the waste material, the waste material acts on the small auger, and the small auger is driven, so that the waste material can smoothly move upwards along the cylinder, as shown in fig. 3 and 4.
The bottom end of the small packing auger 40 is lower than the feed inlet 11, and the top end of the small packing auger is higher than the feed inlet. Without the small auger 40, the waste material is transported upward until a certain amount of waste material has accumulated between the auger 20 and the inner side wall of the barrel 10, and thus the accumulated waste material may block the feed port 11, making the valve plate 30 impossible to open. For this purpose, the small auger 40 is positioned so that the waste accumulated to the level of the feed opening can be transported upwards by the small auger.
Referring to fig. 1, the small packing auger 40 includes a plurality of groups, a plurality of small packing augers of any group of small packing augers are circumferentially distributed along the central line of the cylinder 10, and a plurality of groups of small packing augers are axially distributed along the central line of the cylinder. For example, the number of small augers 40 is two, the first set being located at the feed inlet 11, and the second set being located higher than and in engagement with the first set to ensure that the waste material is continuously conveyed upwards. The second set of small augers is larger in size than the first set, since the clearance between the auger 20 and the barrel 10 is larger the further up. The feed inlet 11 is located between two adjacent small packing augers in the first group of small packing augers.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
