Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0041] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0042] Example: A disc concentrator, see attached document. Figure 1 -Appendix Figure 7 The system includes a concentration plate 1, a concentration mechanism 5, a conditioning tank 2, a conditioning mechanism 6, and a rotating shaft 3. The concentration plate 1 is a hollow disc with one end of its axis tilted to one side relative to the vertical direction. The concentration mechanism is installed inside the concentration plate 1 to separate sludge from water. The conditioning tank 2 is fixedly connected to the top of the concentration plate 1 and is coaxial with it. The conditioning mechanism 6 is used to condition the water mixed with sludge that enters the conditioning tank 2. The rotating shaft 3 is rotatably connected to the conditioning tank 2 and the concentration plate 1 and is coaxial with the concentration plate 1. The rotating shaft 3 provides power to the conditioning mechanism 6 and the concentration mechanism 5 by rotating.

[0043] By setting the rotating shaft 3, power can be provided to both the concentration mechanism 5 and the preparation mechanism 6 at the same time, reducing the number of power mechanism settings and integrating the concentration plate 1 and the preparation container 2 together, thus reducing the space occupied.

[0044] Specifically, the thickening mechanism 5 includes a filter plate 51, a scraper 52, a sludge discharge pipe 53, and a water discharge pipe 54. The filter plate 51 is a circular plate, and the filter plate 51 is coaxially arranged with the thickening plate 1. The inclined top of the filter plate 51 is provided with a sludge discharge hole 511 that penetrates the filter plate 51. The scraper 52 is fixedly connected to the outside of the rotating shaft 3 and scrapes the sludge from the inclined bottom of the filter plate 51 to the sludge discharge hole 511 by following the rotation of the rotating shaft 3. The bottom of the filter plate 51 is fixedly connected to a vertically arranged sludge discharge pipe 53, which is connected to the sludge discharge hole 511. The bottom of the sludge discharge pipe 53 extends downward to the thickening plate 1 to send the sludge sent out of the sludge discharge hole 511 out of the thickening plate 1. The water discharge pipe 54 is fixedly connected to the inclined bottom of the thickening plate 1 and is vertically arranged. The water discharge pipe 54 is used to send out the water filtered by the filter plate 51.

[0045] After the sludge enters the filter plate 51, the water will pass through the filter plate 51 and enter the area below the filter plate 51, then collect at the outlet pipe 54 and be sent out. The sludge, under the action of the scraper 52, is scraped upward and enters the sludge outlet hole 511, and then is sent out through the sludge outlet pipe 53.

[0046] Specifically, the scraper 52 is configured as an arc-shaped plate, and the arc-shaped protrusion of the scraper 52 is configured to be on the side opposite to the rotation direction of the scraper 52.

[0047] Specifically, the concentration mechanism 5 includes a spray pipe 55, which is located at the bottom of the filter plate 51. The spray pipe 55 is used to spray clean water onto the filter plate 51. The spray pipe 55 is located adjacent to the sludge outlet pipe 53. When the scraper 52 rotates, it first passes through the sludge outlet hole 511 and then through the spray pipe 55.

[0048] Specifically, the conditioning mechanism 6 includes a conditioning disc 61, a mixing plate 62, and mixing rods 63. The conditioning disc 61 is disposed inside the conditioning tank 2 and is coaxially arranged with the conditioning tank 2. The inclined top end of the conditioning disc 61 is provided with a discharge hole 611 penetrating the conditioning disc 61, and the inclined bottom end of the conditioning disc 61 is provided with a plurality of auxiliary holes 612 penetrating the conditioning disc 61. The mixing plate 62 is fixedly connected to the outside of the rotating shaft 3 and contacts the top of the conditioning disc 61. The mixing plate 62 is used to push the sludge to move on the conditioning disc 61. The top of the mixing plate 62 is provided with a plurality of spray holes 621 for spraying chemical agents outward. The mixing rods 63 are fixedly connected to the outside of the rotating shaft 3 and are provided in multiples. The multiple mixing rods 63 are arranged around the rotating shaft 3 and are located below the conditioning disc 61.

[0049] After the sludge enters the conditioning tank 2, it first falls onto the conditioning plate 61. The mixing plate 62 pushes the sludge to move on the conditioning plate 61 and sprays chemical agents upward during the movement, so that the chemical agents can fall evenly into the sludge. The mixing plate 62 initially mixes the sludge and chemical agents. During the mixing process, the sludge enters the mixing rod 63 through the discharge hole 611 or the auxiliary hole 612 and is finally mixed by the mixing rod 63.

[0050] Specifically, the mixing plate 62 is configured as an arc-shaped plate, with the protruding side of the arc-shaped plate located on the side opposite to the rotation direction of the mixing plate 62.

[0051] Specifically, a drug inlet pipe is rotatably connected to the top of the rotating shaft 3, and a drug inlet hole communicating with the spray hole 621 is provided on the rotating shaft 3 and the mixing plate 62. The drug inlet hole is connected to the drug inlet pipe.

[0052] Specifically, the conditioning mechanism 6 also includes a mixing hopper 64, which is fixedly connected to the inner wall of the conditioning tank 2 and located between the conditioning plate 61 and the mixing rod 63; the small diameter end of the mixing hopper 64 is located at the bottom of the mixing hopper 64 and the small diameter end of the mixing hopper 64 is provided with a through hole for sludge to pass through.

[0053] With the mixing hopper 64 in place, the sludge falls from the conditioning plate 61 and gradually moves from the mixing hopper 64 to the through hole, achieving a re-mixing of the sludge and chemical agents during the movement process.

[0054] Specifically, a number of blocking rings 65 are fixedly connected to the inner wall of the mixing hopper 64, and each blocking ring 65 is provided with a number of clearance grooves 651 for sludge to pass through.

[0055] This embodiment also includes a temporary storage tank 4, a discharge pipe 41, a first connecting pipe 43, an inlet pipe 42, a second connecting pipe 44, and a feed pipe 21. The temporary storage tank 4 has two parallel temporary storage chambers 40. The discharge pipe 41 is fixedly connected to the bottom of the conditioning tank 2 on its downward-sloping side to discharge the mixed sludge from the conditioning tank 2. Two first connecting pipes 43 are fixedly connected to the end of the discharge pipe 41 away from the conditioning tank 2, and the two first connecting pipes 43 are respectively connected to the two temporary storage chambers 40. Valves are provided on the connecting pipe 43; the liquid inlet pipe 42 is fixedly connected to the top of the downward-sloping side of the concentration plate 1, and the liquid inlet pipe 42 is used to send the sludge in the temporary storage chamber 40 into the concentration plate 1; two second connecting pipes 44 are fixedly connected to the end of the liquid inlet pipe 42 away from the concentration plate 1, and the ends of the second connecting pipes 44 away from the liquid inlet pipe 42 are respectively connected to the two temporary storage chambers 40, and valves are provided on the two second connecting pipes 44; the feed pipe 21 is fixedly connected to the downward-sloping end of the top of the conditioning tank 2.

[0056] With the two temporary storage chambers 40, when one temporary storage chamber 40 is used to inject sludge into the concentration plate 1, the other temporary storage chamber 40 can receive the sludge after the conditioning tank 2 has finished conditioning, so as to realize the simultaneous operation of conditioning and concentration.
